技术领域Technical field
本发明涉及无线通信领域，尤其涉及随机接入信号的发送和接收方法、网络设备和用户设备。The present invention relates to the field of wireless communications, and in particular, to methods for transmitting and receiving random access signals, network equipment and user equipment.
背景技术Background technique
在无线蜂窝通信系统中，随机接入承担着UE(User Equipement，用户设备)与基站之间建立上行通信连接的关键一步。在UE与基站建立上行通信连接过程中，首先取得下行同步。UE通过下行公共信道获取系统信息，例如带宽，帧结构参数，系统帧编号，随机接入信道(RACH，Random Access Channel)信息。在LTE(Long Term Evolut ion，长期演进)网络中，基站通过SIB2(System Informat ion Block2，系统信息块2)将RACH信息通知给UE。然后，UE借助随机接入信道，向基站发送前导信号，前导信号中包含有用于区分不同UE的序列。最后，基站检测序列，识别UE并且完成UE与基站的上行同步。In wireless cellular communication systems, random access is a key step in establishing an uplink communication connection between a UE (User Equipment) and a base station. During the process of establishing an uplink communication connection between the UE and the base station, downlink synchronization is first obtained. The UE obtains system information through the downlink public channel, such as bandwidth, frame structure parameters, system frame number, and random access channel (RACH, Random Access Channel) information. In an LTE (Long Term Evolution, Long Term Evolution) network, the base station notifies the UE of RACH information through SIB2 (System Information Block2). Then, the UE uses the random access channel to send a preamble signal to the base station. The preamble signal contains a sequence used to distinguish different UEs. Finally, the base station detects the sequence, identifies the UE and completes the uplink synchronization between the UE and the base station.
现有LTE中通过RACH传输的随机接入前导(Preamble)的结构如图1所示，其包括CP(Cycl icPrefix，循环前缀)、序列和GT(Guard Time，保护时间)。现有的LTE标准为Preamble定义了五种格式，各个格式的主要参数如表1所示。The structure of the random access preamble (Preamble) transmitted through RACH in existing LTE is shown in Figure 1, which includes CP (CyclicPrefix, cyclic prefix), sequence and GT (Guard Time, guard time). The existing LTE standard defines five formats for Preamble, and the main parameters of each format are shown in Table 1.
表1LTE前导格式及其主要参数表Table 1 LTE preamble format and its main parameters
从上面可以看出，在现有LTE标准中随机接入前导占用时间太长，而且可用于随机接入前导的序列的数量有限，故容易出现多个UE同时使用相同序列进行随机接入的情况，导致比较高的冲突概率。As can be seen from the above, in the existing LTE standard, the random access preamble takes too long, and the number of sequences that can be used for the random access preamble is limited, so it is easy for multiple UEs to use the same sequence for random access at the same time. , leading to a relatively high probability of conflict.

Different UEs can generate preambles with different resource patterns. Therefore, during the random access process, the network device can be made to perform random access according to the random access signal. The UE is identified by the resource pattern contained in the access signal. In addition, since the resource pattern in the implementation of the present invention specifies the resource occupancy of the random access preamble in at least one dimension of the three-dimensional resources (frequency resources, time resources and sequence resources), for a specific preamble, in There are many choices for the resource positions that can be occupied in each dimension of resources. By combining the resource positions in different dimensions, there can be a lot of resource patterns. Each resource pattern can be used to generate a random access preamble. Therefore, in the embodiment of the present invention, there are many choices when generating the random access preamble, which reduces the probability of collision when multiple UEs in the same cell perform random access at the same time.

In this embodiment, the pattern set may be stored in the UE in advance, or may be notified to the UE by the network device. In this embodiment, the two resource patterns are different, which may refer to the type of resource pattern (for example, time hopping pattern, frequency hopping pattern), or may refer to the same type due to different resources occupied by each preamble or sub-preamble. The resulting patterns are different, for example, hopping pattern 1 specifies that the sub-preamble is sent on sub-band 1, sub-band 3, and sub-band 4, and hopping pattern 2 specifies that the sub-preamble is sent on sub-band 1, sub-band 2, and sub-band 4.

A sub-preamble is sent within the duration, and the UE's transmit beam scanning information includes the transmit beams that need to be scanned and the scanning time of each transmit beam. Correspondingly, step S300 may specifically include: sending the random access signal according to the scanning time of the transmit beam of the UE.

Accordingly, step S100 may specifically include: determining the resource pattern according to the structural information of the RACH, where the resource pattern is specifically used to specify the resources occupied by the preamble in the RACH.

The resource pattern is determined based on at least two of the channel conditions.
图4A示出了一种可能的RACH的结构，该图中的RACH包含F个子带，各个子带的带宽可以相同，不同子带上用于发送一个前导的时间长度也可以相同。在一个RACH的时间长度内，一个随机接入信号包括F个子带上的所有前导，子带i(i＝1，2，…F)上有Ni个前导，子带i上第j个前导包含Kij个子前导(j＝1，2，…Ni)。不同子带上的前导的数目Ni可以相同，同一个子带上用于发送各个前导的时间长度可以相同也可以不相同，不同前导所包含的子前导的数目Kij可以相同也可以不同。Figure 4A shows a possible RACH structure. The RACH in this figure includes F subbands. The bandwidth of each subband can be the same, and the length of time used to send a preamble on different subbands can also be the same. Within the time length of a RACH, a random access signal includes all preambles on F subbands. There are Ni preambles on subband i (i=1, 2,...F), and the jth preamble on subband i contains Kij sub-preambles (j=1, 2,...Ni). The number Ni of preambles on different subbands may be the same, the length of time used to send each preamble on the same subband may be the same or different, and the number Kij of subpreambles included in different preambles may be the same or different.
图4B示出了另一种可能的RACH的结构，该图中的RACH也包含F个子带，但是各个子带的宽度可以不同，不同子带上用于发送一个前导的时间长度可以不同。在一个RACH的时间长度内，一个随机接入信号包括F个子带上的所有前导，子带i上有Ni个前导，子带i上第j个前导包含Kij个子前导(j＝1，2，…Ni)。不同子带上的前导的数目Ni可以不同，一个子带上用于发送各个前导的时间长度可以相同也可以不同，不同前导所包含的子前导的数目Kij可以相同也可以不同。在另一实施例中，在图4B所示RACH的结构中，任意两个子带的子带宽度相同，但是两个子带上用于发送一个前导的时间长度不同；或者是任意两个子带的子带宽度不相同、但是两个子带上用于发送一个前导的时间长度相同。Figure 4B shows another possible RACH structure. The RACH in this figure also includes F subbands, but the width of each subband can be different, and the length of time used to send a preamble on different subbands can be different. Within the length of time of a RACH, a random access signal includes all preambles on F subbands. There areNi preambles on subband i. The jth preamble on subband i contains Kij sub-preambles (j=1, 2,...Ni). The number Ni of preambles on different subbands may be different, the length of time used to send each preamble on a subband may be the same or different, and the number Kij of subpreambles included in different preambles may be the same or different. In another embodiment, in the RACH structure shown in Figure 4B, the sub-band widths of any two sub-bands are the same, but the time lengths used to send a preamble on the two sub-bands are different; or the sub-band widths of any two sub-bands are different. The band widths are not the same, but the length of time used to send a preamble is the same on both subbands.
如图4A和图4B所示，随机接入信号包含多个前导，此时，步骤S100中确定的资源图案具体为所有的前导指定了所占用的资源。例如，为每个前导指定所使用的子带，发送时间，该前导所采用的序列中的至少一个。As shown in Figure 4A and Figure 4B, the random access signal includes multiple preambles. At this time, the resource pattern determined in step S100 specifically specifies the resources occupied by all the preambles. For example, for each preamble, specify the subband used, the time of transmission, and at least one of the sequences used by the preamble.
在图4A和图4B中，子带i上第j个前导包含Kij个子前导(j＝1，2，…Ni)，子前导的具体结构如图5所示。在一个实施例中子前导可以只包括序列，如图5所示的结构8。在另外的实施例中，除了包括序列外，子前导还可以包括GT1、GT2和CP中的至少一个。GT1、GT2为保护时间，不传送数据，可用于波束切换或者保护后续通信。CP为循环前缀(Cycl ic Prefix)。序列可以是具有良好自相关和互相关的任意序列，例如Zadoff-Chu序列，m序列等。GT1、CP、序列、以及GT2的时间长度可以是网络设备指定，或者UE根据来自网络设备的信令决定，或者UE自我决定。RACH可以由频域上的F个子带、各个子带上的一个或者多个前导和/或子前导、以及形成子前导的序列集共同来表示。In Figures 4A and 4B, the j-th preamble on sub-band i includes Kij sub-preambles (j=1, 2,...Ni). The specific structure of the sub-preambles is shown in Figure 5. In one embodiment, the sub-preamble may only include sequences, such as structure 8 shown in Figure 5 . In other embodiments, in addition to the sequence, the sub-preamble may also include at least one of GT1, GT2, and CP. GT1 and GT2 are guard times, do not transmit data, and can be used for beam switching or protecting subsequent communications. CP is Cyclic Prefix. The sequence can be any sequence with good autocorrelation and cross-correlation, such as Zadoff-Chu sequence, m-sequence, etc. The time lengths of GT1, CP, sequence, and GT2 may be specified by the network device, or determined by the UE according to signaling from the network device, or determined by the UE itself. RACH may be collectively represented by F subbands in the frequency domain, one or more preambles and/or subpreambles on each subband, and a sequence set forming the subpreamble.
位于各个子带、时间上的前导或者子前导，使用的波形参数(例如，子载波间隔、CP长度、保护间隔)可以完全不相同，也可以部分相同，也可以完全相同。前导的结构(例如，包含子前导、或者不包含子前导)、子前导的序列可以由网络设备指定，或者由UE决定。The preamble or sub-preamble located in each sub-band and time may use waveform parameters (for example, sub-carrier spacing, CP length, guard interval) that are completely different, partially the same, or completely identical. The structure of the preamble (for example, including a sub-preamble or not including a sub-preamble) and the sequence of the sub-preamble may be specified by the network device or determined by the UE.
图6示出了单子带的前导的七种可能的结构：前导1、前导2、前导3、前导4、前导5、前导6和前导7。在本实施例，前导1中仅有一个子前导，也就是其自身。前导2包括一个CP、一个GT2和K2个序列，其中CP位于前导2的起始位置，GT2位于前导2的终止位置。前导2可以被认为是由具有图5所示的结构6、结构7和结构8的子前导构成。前导3包括位于每个序列之前的CP，位于最后一个序列之后的GT2，和K3个序列，其可以被认为是由具有图5所示的结构6和结构2的子前导构成。前导4包括K4个序列，以及位于每个序列之前的CP，该前导4可以被认为是由具有图5所示结构6的子前导构成。前导5包括位于K5个序列，位于每个序列之前的CP，和位于每个序列之后的GT2构成，该前导5可以被认为是由具有图5所示的结构2的子前导构成。前导6包括位于第一个序列之前的GT1和CP，位于最后一个序列之前的CP，位于最后一个序列之后的GT2，和K6个序列，该前导6可以被认为是由具有图5所示的结构2和结构3的子前导组成。前导7包括位于第一个序列之前的GT1和CP，位于第一个序列之后的GT2，位于最后一个序列之前的CP、位于最后一个序列之后的GT2，和K7个序列，该前导7可以被看成是由具有图5所示的结构1和结构2的子前导构成。每个前导中的序列，如前文所描述的，可以根据跳时-序列图案来选取。在不同的前导结构实例中，序列个数、序列长度可以完全不相同，也可以部分相同，也可以完全相同。在同一个前导结构中，各个序列可以完全不相同，也可以部分相同，也可以完全相同。Figure 6 shows seven possible structures of the preamble of a single subband: preamble1, preamble2, preamble3, preamble4, preamble5, preamble6 and preamble7. In this embodiment, there is only one sub-preamble in Preamble 1, which is itself. Leading 2 includes a CP, a GT2 and K2 sequences, where CP is located at the starting position of Leading 2 and GT2 is located at the ending position of Leading 2. Preamble 2 can be considered to be composed of sub-preambles having structure 6, structure 7 and structure 8 shown in Figure 5. Preamble 3 includes CP before each sequence, GT2 after the last sequence, and K3 sequences, which can be considered to be composed of sub-preambles with structure 6 and structure 2 shown in Figure 5. The preamble 4 includes K4 sequences, and the CP located before each sequence. The preamble 4 can be considered to be composed of sub-preambles with the structure 6 shown in Figure 5.

The leading 7 includes GT1 and CP before the first sequence, GT2 after the first sequence, CP before the last sequence, GT2 after the last sequence, and K7 sequences, which can be seen It is composed of sub-preambles having structure 1 and structure 2 shown in Figure 5. The sequences in each preamble can be selected based on the time-hopping-sequence pattern as described previously. In different leading structure instances, the number of sequences and sequence lengths may be completely different, partially the same, or completely identical. In the same leader structure, each sequence can be completely different, partially the same, or completely identical.
图7A示出了单子带的随机接入信号的前导所对应的一种跳时图案，在该图案中，至少有一个可用于发送子前导的时间资源(例如，时间t2)未被用来发送任何子前导。在本发明实施中，附图中虚线框表示其所在位置未被用来发送任何前导或者子前导。根据图7A所示的跳时图案生成的随机接入信号的前导包括7个子前导，分别占用了除时间t2以外所有时间(时间t1，t3，t4，t5，t6，t7，t8)的子前导，各个子前导所采用的序列相同。在其它的实施中，各个子前导所采用的序列可以部分相同，也可以完全不同。前导中各个子前导所占用的时间资源的位置形成了一个独特的资源图案，可以被用来标识一个特定的前导或者UE。在其它的实施例中，即使有另外一个前导的子前导所占用的时间资源和图7A中的完全一样，但是，只要子前导所采用的序列不同，也能起到标识一个特定的前导或者UE的作用。UE在进行随机接入时，可以发送包含具有图7A所示资源图案的前导的上行随机接入信号，利用图7A所述的资源结构标识UE。如果改变图7A中不发送任何子前导的时间所在的位置或者不发送任何子前导的发送时间的数量，就得到了另一个前导。Figure 7A shows a time hopping pattern corresponding to the preamble of a single sub-band random access signal. In this pattern, at least one time resource (for example, time t2) available for transmitting the sub-preamble is not used for transmission. any subpreamble. In the implementation of the present invention, the dotted box in the drawing indicates that its location is not used to send any preamble or sub-preamble. The preamble of the random access signal generated according to the time hopping pattern shown in Figure 7A includes 7 sub-preambles, which occupy all times (times t1, t3, t4, t5, t6, t7, t8) except time t2. , the sequence used by each sub-preamble is the same. In other implementations, the sequences used by each sub-preamble may be partially the same or completely different. The position of the time resources occupied by each sub-preamble in the preamble forms a unique resource pattern, which can be used to identify a specific preamble or UE. In other embodiments, even if there is another preamble whose sub-preamble occupies exactly the same time resources as in Figure 7A, as long as the sequence used by the sub-preamble is different, it can still identify a specific preamble or UE. role. When performing random access, the UE may send an uplink random access signal including a preamble with the resource pattern shown in Figure 7A, and use the resource structure described in Figure 7A to identify the UE. If the position of the time when no sub-preamble is sent or the number of the time when no sub-preamble is sent is changed in Figure 7A, another preamble is obtained.

In this pattern, there is a sub-preamble in each time resource, and the sequence used by each sub-preamble is a sequence selected from the sequence set corresponding to the position of the time resource occupied by the sub-preamble. The sequences taken at each time can be exactly the same, partially the same, or completely different.
图7C示出了单子带的随机接入信号的前导所对应的另一种资源图案：跳时-序列图案。在该图案中，在至少一个可用于发送子前导的时间资源内不发送任何子前导，其它的时间资源上的子前导所携带的序列是根据其所在的位置从序列集中选取的。Figure 7C shows another resource pattern corresponding to the preamble of a single subband random access signal: a time-hopping sequence pattern. In this pattern, no sub-preamble is sent within at least one time resource that can be used to send the sub-preamble, and the sequences carried by the sub-preambles on other time resources are selected from the sequence set according to their positions.
图8A示出了多子带的随机接入信号的前导所使用的另一种资源图案：跳频图案。在该图案中，至少有一个子带上不发送任何子前导，例如，图8A所示的子带f2。如图8A所示，在该结构中其它所有子带上的子前导都占用同一时间资源，各个子前导所采用的序列相同。在其它的实施例中，一个特定的前导中的每一个子前导所采用的序列与该前导的跳频图案相关联，也可以部分相同，也可以完全不同。Figure 8A shows another resource pattern used by the preamble of a multi-subband random access signal: a frequency hopping pattern. In this pattern, no sub-preamble is sent on at least one sub-band, for example, sub-band f2 shown in Figure 8A. As shown in Figure 8A, in this structure, the sub-preambles on all other sub-bands occupy the same time resources, and the sequences used by each sub-preamble are the same. In other embodiments, the sequence used by each sub-preamble in a specific preamble is associated with the frequency hopping pattern of the preamble, and may be partially the same or completely different.
图8B示出了多子带的随机接入信号的前导所使用的另一种资源图案：跳序列图案。在该资源图案中，每个子带上均有一个子前导，每个子带上的子前导所采用的序列均是根据其所在频带从序列集中选择的，这些序列由前导的跳序列图案指定。Figure 8B shows another resource pattern used by the preamble of a multi-subband random access signal: a hopping sequence pattern. In this resource pattern, there is a sub-preamble on each sub-band, and the sequences used by the sub-preamble on each sub-band are selected from the sequence set according to the frequency band in which they are located. These sequences are specified by the hopping sequence pattern of the preamble.
图8C示出了多子带的随机接入信号的前导所使用的又一种资源图案：跳频-序列图案。在该图案中，至少有一个子带(例如子带f2)不用于发送任何子前导，其它子带均用于发送子前导，且每个子前导所采用的序列与其对应的子带相关，例如，采用序列k的子前导只能在子带fk上发送。FIG. 8C shows yet another resource pattern used by the preamble of a multi-subband random access signal: a frequency hopping-sequence pattern. In this pattern, at least one subband (such as subband f2) is not used to send any sub-preamble, other sub-bands are used to send sub-preambles, and the sequence used by each sub-preamble is related to its corresponding sub-band, for example, A subpreamble with sequence k can only be sent on subband fk.
图8D示出了多子带的随机接入信号的前导所使用的又一种资源图案：跳时-频图案。在该图案中，在至少一个子带上有至少一个可用于发送子前导的时间资源未发送任何子前导(例如子带f1的发送时间t2)。在该图案中，只是使用了特定发送时间和特定的子带发送子前导，各个子前导所采用的序列相同。在其它实施例中，各个子前导所采用的序列可以不同。每一个子前导(或者其采用的序列)与包含该子前导的前导的跳时-频图案相关联，不同子前导对应的跳时-频图案可以完全相同，也可以部分相同，也可以完全不同。Figure 8D shows another resource pattern used by the preamble of a multi-subband random access signal: a time-frequency pattern. In this pattern, there is at least one time resource available for transmitting a sub-preamble on at least one sub-band without transmitting any sub-preamble (for example, the transmission time t2 of sub-band f1). In this pattern, only a specific transmission time and a specific subband are used to transmit the sub-preamble, and the sequence used by each sub-preamble is the same. In other embodiments, the sequences adopted by each sub-preamble may be different. Each sub-preamble (or the sequence it adopts) is associated with the time-hopping-frequency pattern of the preamble containing the sub-preamble. The time-hopping-frequency patterns corresponding to different sub-preambles can be exactly the same, partially the same, or completely different. .
图8E示出了多子带的随机接入信号的前导所使用的再一种资源图案：跳时-频-序列图案。在该结构中，在至少一个子带上有至少一个可用于发送子前导的时间资源上未发送任何子前导(例如子带f1的时间t2)，每个子前导所采用的序列和其所在的子带位置和时间资源所在的位置相关。Figure 8E shows yet another resource pattern used by the preamble of a multi-subband random access signal: a time-hopping-frequency-sequence pattern. In this structure, no sub-preamble is sent on at least one time resource available for sending a sub-preamble on at least one sub-band (for example, time t2 of sub-band f1), the sequence used by each sub-preamble and the sub-preamble in which it is located. The location and time resources are related to the location.
多子带接入信号的前导还可以具有不同的波形参数。如图9A所示，在不同子带上的前导具有相同的子带带宽和相同的前导时间长度下，不同子带内子载波的间隔不同，各个子前导的长度随着子载波间隔的倍增而倍减。如图9B所示，在不同子带上的前导具有相同的前导序列长度和相同的前导时间时间长度下，子带宽度随着子载波间隔倍增而倍增。The preambles of multi-subband access signals can also have different waveform parameters. As shown in Figure 9A, when the preambles on different subbands have the same subband bandwidth and the same preamble time length, the intervals between subcarriers in different subbands are different, and the length of each subpreamble doubles as the subcarrier interval increases. reduce. As shown in Figure 9B, when the preambles on different subbands have the same preamble sequence length and the same preamble time length, the subband width doubles as the subcarrier spacing doubles.
本发明实施例提供的发送随机接入信号的方法可以应用于UE与网络设备建立上行通信。图10A示出了UE与网络设备(具体为网络设备)建立上行通信的过程，该流程包括：The method for sending a random access signal provided by the embodiment of the present invention can be applied to establish uplink communication between a UE and a network device. Figure 10A shows the process of establishing uplink communication between a UE and a network device (specifically, a network device). The process includes:
步骤S401，网络设备发送下行系统信息。下行系统信息可以包括如下信息中的任意一种或者多种：RACH的结构，RACH所在的时间位置及时间长度、RACH所在的频率位置及载波数量、RACH包含的前导/子前导个数，前导的跳动图案的集合信息(例如，集合的编号)，RACH内的网络设备的用于接收通过RACH传输的随机接入信号的各个接收波束的ID以及扫描时间、扫描频率，前导格式，网络设备的波束的一致性信息，时间提前量等等。在另外的实施例中，下行系统信息可以包括上述信息的索引(index)。波束的一致性信息是指同一个对象的发送波束和接收波束是否对应，即，只要知道特定对象的发送波束，就可以推导出接收波束，反之亦然。Step S401: The network device sends downlink system information. Downlink system information may include any one or more of the following information: the structure of RACH, the time location and time length of RACH, the frequency location and number of carriers of RACH, the number of preambles/sub-preambles included in RACH, the number of preambles Set information of the beat pattern (e.g., number of the set), ID of each receive beam used by the network device within the RACH to receive the random access signal transmitted through the RACH, as well as scan time, scan frequency, preamble format, beam of the network device Consistency information, time advance, etc. In another embodiment, the downlink system information may include an index of the above information. The consistency information of the beam refers to whether the transmit beam and the receive beam of the same object correspond. That is, as long as the transmit beam of a specific object is known, the receive beam can be deduced, and vice versa.
步骤S402，UE与网络设备执行下行同步。在下行同步后，UE可以获取RACH的时间资源、频率资源等信息。UE在该步骤中，还可以获取下行通信中的UE的最佳接收波束的ID、网络设备的最佳发送波束的ID。UE根据已有的信息，从网络设备指定的跳动图案的集合中选择一个跳动图案，然后根据跳动图案生成随机接入信号。在该步骤中，UE可以采用图3所示实施例提供的方法发送随机接入信号。Step S402: The UE and the network device perform downlink synchronization. After downlink synchronization, the UE can obtain RACH time resources, frequency resources and other information. In this step, the UE may also obtain the ID of the best receiving beam of the UE and the ID of the best transmitting beam of the network device in downlink communication. The UE selects a hopping pattern from the set of hopping patterns specified by the network device based on existing information, and then generates a random access signal based on the hopping pattern. In this step, the UE may use the method provided by the embodiment shown in Figure 3 to send a random access signal.
步骤S403，UE与网络设备分别完成随机接入信号的发送和接收。Step S403: The UE and the network device respectively complete sending and receiving random access signals.
步骤S404，网络设备发送随机接入响应，UE在收到随机接入响应后发送可以包含UE身份信息等的上行信息，网络设备再发送下行信息供UE进行冲突检测，最后完成随机接入过程。Step S404: The network device sends a random access response. After receiving the random access response, the UE sends uplink information that may include UE identity information, etc. The network device then sends downlink information for the UE to perform conflict detection, and finally completes the random access process.
步骤S405，建立上行通信连接。Step S405: Establish an uplink communication connection.
在另一实施例中，在步骤S402中，选择的跳动图案与网络设备的发送波束ID之间有一一对应关系，即，特定的跳动图案可以标识网络设备的发送波束ID。相应地，在步骤S403中，网络设备还可以根据跳动图案得到网络设备发送波束ID。In another embodiment, in step S402, there is a one-to-one correspondence between the selected jitter pattern and the transmission beam ID of the network device, that is, a specific jitter pattern can identify the transmission beam ID of the network device. Correspondingly, in step S403, the network device can also obtain the network device transmission beam ID according to the jitter pattern.
在另一实施例中，在步骤S402中，生成的随机接入信号中包含网络设备的发送波束信息。相应地，在步骤S403中，网络设备还可以检测到网络设备的发送波束信息。在步骤S403中，网络设备对接收信号进行检测，检测跳动图案，并得到接收跳动图案对应的前导的网络设备的最佳接收波束的ID。在步骤S404中，网络设备还可以向UE发送信息。例如，网络设备还可以把检测的跳动图案通知UE，UE根据网络设备检测结果获知UE的最佳上行发送波束信息。再例如，把步骤S403中网络设备的最佳接收波束的ID通知UE。再例如，网络设备分配上行通信资源给UE，解决多个UE的随机接入冲突等。In another embodiment, in step S402, the generated random access signal includes the transmission beam information of the network device. Correspondingly, in step S403, the network device may also detect the transmission beam information of the network device. In step S403, the network device detects the received signal, detects the jitter pattern, and obtains the ID of the best receiving beam of the network device that receives the preamble corresponding to the jitter pattern. In step S404, the network device may also send information to the UE. For example, the network device can also notify the UE of the detected jitter pattern, and the UE can learn the best uplink transmission beam information of the UE based on the detection results of the network device. For another example, the UE is notified of the ID of the best receiving beam of the network device in step S403. For another example, the network device allocates uplink communication resources to UEs to resolve random access conflicts of multiple UEs.
图10B示出了随机接入的一信令流程，该信令流程包括：Figure 10B shows a signaling process for random access. The signaling process includes:
步骤S406，网络设备发送下行系统信息。下行系统信息可以包括网络设备的用于接收在RACH上传输的随机接入信号的接收波束信息和跳动图案的集合信息。下行系统信息中还可以包括，RACH在网络设备进行接收波束扫描时所呈现出的结构。Step S406: The network device sends downlink system information. The downlink system information may include set information of reception beam information and jitter patterns of the network device used to receive random access signals transmitted on the RACH. The downlink system information may also include the structure of the RACH when the network device performs receive beam scanning.
步骤S407，UE根据网络设备的用于接收随机接入信号的接收波束信息和UE的用于发送随机接入信号的发送波束信息选择跳动图案，根据选择的跳动图案生成随机接入信号，并将该随机接入信号发送给网络设备。在该步骤中，UE可以采用图3所示实施例提供的方法发送随机接入信号。Step S407: The UE selects a jumping pattern based on the receiving beam information of the network device for receiving random access signals and the UE's transmitting beam information for transmitting random access signals, generates a random access signal based on the selected jumping pattern, and generates a random access signal. The random access signal is sent to the network device. In this step, the UE may use the method provided by the embodiment shown in Figure 3 to send a random access signal.
步骤S408，网络设备检测接收到的随机接入信号的跳动图案，根据检测到的跳动图案，为发送上述随机接入信号的UE分配用于上行通信的通信资源。Step S408: The network device detects the jitter pattern of the received random access signal, and allocates communication resources for uplink communication to the UE that sends the random access signal based on the detected jitter pattern.
图10B所示的信令流程可适用于但不限于如下场景下的随机接入：在上行接入过程中需要进行波束扫描，但已经明确了需要扫描的由网络设备的接收波束和UE的发送波束构成的波束对的情况下的随机接入；UE的发送波束和网络设备的接收波束都不需要进行波束扫描的情况下的随机接入。The signaling process shown in Figure 10B can be applied to, but is not limited to, random access in the following scenarios: beam scanning is required during the uplink access process, but the receiving beams of the network device and the transmitting beams of the UE that need to be scanned have been clarified. Random access in the case of beam pairs formed by beams; random access in the case where neither the UE's transmit beam nor the network device's receive beam needs to perform beam scanning.
图10C示出了随机接入的又一信令流程，该流程包括：Figure 10C shows another signaling process of random access, which includes:
步骤S409，网络设备发送下行系统信息。下行系统信息可以包括网络设备的用于接收在RACH上传输的随机接入信号的接收波束信息和跳动图案的集合信息。下行系统信息中还可以包括，RACH在网络设备进行接收波束扫描时所呈现出的结构。Step S409: The network device sends downlink system information. The downlink system information may include set information of reception beam information and jitter patterns of the network device used to receive random access signals transmitted on the RACH. The downlink system information may also include the structure of the RACH when the network device performs receive beam scanning.
步骤S410，UE选择需要用于发送随机接入信号的发送波束，根据选择的发送波束和网络设备的用于接收在RACH上传输的随机接入信号的接收波束信息，选择跳动图案，根据选择的跳动图案生成随机接入信号，并将该随机接入信号发送给网络设备。在本步骤中，可以选择一个跳动图案，也可以选择两个或者两个以上的跳动图案，本发明实施例不做限制。在该步骤中，UE可以采用图3所示实施例提供的方法发送随机接入信号。Step S410: The UE selects a transmit beam that needs to be used to transmit a random access signal, and selects a jumping pattern based on the selected transmit beam and the receive beam information of the network device used to receive the random access signal transmitted on the RACH. The bounce pattern generates a random access signal and sends the random access signal to the network device. In this step, one jumping pattern can be selected, or two or more jumping patterns can be selected, which is not limited by the embodiment of the present invention. In this step, the UE may use the method provided by the embodiment shown in Figure 3 to send a random access signal.
步骤S411，网络设备根据检测到的跳动图案，确定网络设备的最佳接收波束，为UE分配上行资源。Step S411: The network device determines the best receiving beam of the network device based on the detected jitter pattern, and allocates uplink resources to the UE.
图10C所述的信令流程适用于UE已知用于发送随机接入信号的最佳发送波束的情况下的随机接入。The signaling process described in Figure 10C is applicable to random access in the case where the UE knows the best transmission beam for transmitting the random access signal.
图10D示出了随机接入的又一信令流程，该流程包括：Figure 10D shows another signaling process of random access, which includes:
步骤S412，网络设备发送下行系统信息。下行系统信息可以包括网络设备的用于接收在RACH上传输的随机接入信号的接收波束信息和跳动图案的集合信息。下行系统信息中还可以包括，RACH在网络设备进行接收波束扫描时所呈现出的结构。Step S412: The network device sends downlink system information. The downlink system information may include set information of reception beam information and jitter patterns of the network device used to receive random access signals transmitted on the RACH. The downlink system information may also include the structure of the RACH when the network device performs receive beam scanning.
步骤S413，UE根据下行系统信息中获知网络设备的用于接收随机接入信号的接收波束，根据网络设备的用于接收在RACH上传输的随机接入信号的接收波束选择跳动图案，根据选择的跳动图案生成随机接入信号，并将该随机接入信号发送给网络设备。在本步骤中，可以选择一个跳动图案，也可以选择两个或者两个以上的跳动图案，本发明实施例不做限制。在本步骤中，UE可以采用图3所示实施例提供的方法发送随机接入信号。Step S413: The UE learns the receiving beam of the network device for receiving the random access signal from the downlink system information, selects the jumping pattern according to the receiving beam of the network device for receiving the random access signal transmitted on the RACH, and selects the beating pattern according to the selected The bounce pattern generates a random access signal and sends the random access signal to the network device. In this step, one jumping pattern can be selected, or two or more jumping patterns can be selected, which is not limited by the embodiment of the present invention. In this step, the UE may use the method provided by the embodiment shown in Figure 3 to send a random access signal.
步骤S414，网络设备根据检测到的跳动图案，确定UE的最佳发送波束，并为UE分配上行资源。Step S414: The network device determines the optimal transmission beam of the UE based on the detected jitter pattern, and allocates uplink resources to the UE.
图10D所示的信令流程可适用于在UE知道网络设备的最佳接收波束的情况下的随机接入。The signaling process shown in Figure 10D may be applicable to random access in the case where the UE knows the best receiving beam of the network device.
图10E示出了随机接入的又一信令流程，该流程包括：Figure 10E shows another signaling process of random access, which includes:
步骤S415，网络设备发送下行系统信息。下行系统信息可以包括网络设备的用于接收在RACH上传输的随机接入信号的接收波束信息和跳动图案的集合信息。下行系统信息中还可以包括，RACH在网络设备进行接收波束扫描时所呈现出的结构。Step S415: The network device sends downlink system information. The downlink system information may include set information of reception beam information and jitter patterns of the network device used to receive random access signals transmitted on the RACH. The downlink system information may also include the structure of the RACH when the network device performs receive beam scanning.
步骤S416，UE根据下行系统信息中获知网络设备的用于接收在RACH上传输的随机接入信号的接收波束，根据网络设备的用于接收在RACH上传输的随机接入信号的接收波束选择跳动图案，根据选择的跳动图案生成随机接入信号，并将该随机接入信号发送给网络设备。在本步骤中，可以选择一个跳动图案，也可以选择两个或者两个以上的跳动图案，本发明实施例不做限制。在本步骤中，UE可以采用图3所示实施例提供的方法发送随机接入信号。Step S416: The UE learns from the downlink system information the receiving beam of the network device used to receive the random access signal transmitted on the RACH, and selects the jump according to the receiving beam of the network device used to receive the random access signal transmitted on the RACH. pattern, generate a random access signal according to the selected beating pattern, and send the random access signal to the network device. In this step, one jumping pattern can be selected, or two or more jumping patterns can be selected, which is not limited by the embodiment of the present invention. In this step, the UE may use the method provided by the embodiment shown in Figure 3 to send a random access signal.
步骤S417，网络设备根据检测到的跳动图案，确定网络设备的最佳接收波束和UE的最佳发送波束，并且分配上行资源。Step S417: The network device determines the optimal receiving beam of the network device and the optimal transmitting beam of the UE based on the detected jitter pattern, and allocates uplink resources.
图10E所示的信令流程可适用于UE不知道其用于发送随机接入信号的发送波束和网络设备的接收波束的情况下的随机接入。The signaling process shown in Figure 10E may be applicable to random access in the case where the UE does not know the transmit beam it uses to transmit the random access signal and the receive beam of the network device.
用于一个RACH的资源包括时间、频率、序列三个维度的资源。基于这些资源，可以将跳动图案划分成多个互相没有交集的结合。在UE发送随机接入信号之前，网络设备将跳动图案的集合划分信息和/或可供UE选择的跳动图案的结合的信息通知UE。通知方式可以是用信令直接指示，也可以是通过特殊的下行信号设计，隐式指定(例如，可以采取类似于LTE中识别不同帧结构的方法)。划分跳动图案时，可以根据UE对RACH的需求来进行。例如根据UE与网络设备之间的距离，是否需要进行波束扫描。The resources used for a RACH include resources in three dimensions: time, frequency, and sequence. Based on these resources, the beating pattern can be divided into multiple combinations that do not overlap with each other. Before the UE sends a random access signal, the network device notifies the UE of the set division information of the hopping patterns and/or the combination information of the hopping patterns that can be selected by the UE. The notification method can be directly indicated by signaling, or it can be specified implicitly through special downlink signal design (for example, a method similar to the method used to identify different frame structures in LTE can be adopted). When dividing the beating pattern, it can be done according to the UE's requirements for RACH. For example, depending on the distance between the UE and the network device, whether beam scanning is required.
图11示出了一个单子带RACH的结构一个示例。在本实施例中，RACH只有一个子带，该子带的频域宽度为72个子载波，子载波间隔是60KHz；在RACH的时长内UE发送有4个前导，每个前导的时长等于两个子前导的时长。各个前导之间在时间上可以连续，也可以不连续，但是互相不交叠。Figure 11 shows an example of the structure of a single subband RACH. In this embodiment, RACH has only one subband, the frequency domain width of this subband is 72 subcarriers, and the subcarrier spacing is 60KHz; within the duration of RACH, the UE sends 4 preambles, and the duration of each preamble is equal to two subcarriers. The length of the leader. Each leader can be continuous or discontinuous in time, but it does not overlap with each other.
针对在图11所示结构的RACH上传输的随机接入信号，网络设备在进行接收波束扫描时对其进行接收所呈现出的RACH的结构如图12所示。在本实施例中，网络设备在两个接收波束上进行扫描，在每个接收波束上均接收到两个前导。For the random access signal transmitted on the RACH with the structure shown in Figure 11, the structure of the RACH presented by the network device when receiving the received beam scan is as shown in Figure 12. In this embodiment, the network device scans on two receive beams and receives two preambles on each receive beam.
在一个实施例中，在生成具有图11所示结构的信号时，UE可以从是图13A、图13B和图13C所示跳动图案中选择任意一种来用于生成和发送前导。In one embodiment, when generating a signal with the structure shown in Figure 11, the UE can select any one of the hopping patterns shown in Figure 13A, Figure 13B and Figure 13C for generating and sending the preamble.
图13A所示的跳动图案1～3可以用于只在一个接收波束中发送前导，图13B和图13C所示的跳动图案4～10可以用于在多个接收波束内发送前导。The hopping patterns 1 to 3 shown in FIG. 13A can be used to transmit the preamble in only one receive beam, and the hopping patterns 4 to 10 shown in FIGS. 13B and 13C can be used to transmit the preamble in multiple receive beams.
图13A可以适用于已确定UE的最佳发送波束和网络设备的最佳接收波束的场景，UE可以采用该图中所示的图案生成前导，用来发送调度请求，切换请求等。由于不需要进行波束扫描，图13A中所示结构的图案指定了较少的子前导，从而可以占用较少的开销。Figure 13A can be applied to a scenario where the best transmit beam of the UE and the best receive beam of the network device have been determined. The UE can use the pattern shown in the figure to generate a preamble to send scheduling requests, handover requests, etc. Since beam scanning is not required, the pattern of the structure shown in Figure 13A specifies fewer sub-preambles and thus can occupy less overhead.
图13B和图13C可以适用于没有确定UE的最佳发送波束和/或网络设备的接收波束的场景，UE可以采用该图所示的图案生成前导，以在随机接入过程中支持波束扫描。例如，UE在进行第一次上行同步UE时，或者UE与网络设备之间的上行链路发生链路中断(l inkfai lure)时，UE和网络设备就需要进行波束扫描以确定UE的最佳发送波束和网络设备的最佳接收波束，此时就可以采用图13B和图13C所示图案中任意一种跳动图案来生成前导，该前导可以被用来确定UE的最佳发送波束和网络设备的最佳接收波束。Figures 13B and 13C can be applied to scenarios where the optimal transmit beam of the UE and/or the receive beam of the network device has not been determined. The UE can generate a preamble using the pattern shown in the figure to support beam scanning during the random access process. For example, when the UE synchronizes the UE for the first time in uplink, or when the uplink between the UE and the network device is interrupted (linkfai lure), the UE and the network device need to perform beam scanning to determine the best position of the UE. At this time, any of the beating patterns shown in Figure 13B and Figure 13C can be used to generate a preamble. This preamble can be used to determine the best transmission beam and network equipment for the UE. the best receiving beam.
在本发明实施中，可以考虑在由于在随机接入的过程中同时完成对UE的发送波束和/或接收波束的扫描，此时UE在选择跳动图案时，需要确保每个波束的扫描时间内至少有一个子前导或者前导。In the implementation of the present invention, it can be considered that since the scanning of the transmit beam and/or the receive beam of the UE is completed simultaneously during the random access process, the UE needs to ensure the scanning time of each beam when selecting the jumping pattern. There is at least one sub-leader or leader.
在图13A和图13B所示的跳动图案中，跳动图案1和跳动图案4常适用于无线链路状况好的UE(如距离网络设备近)，跳动图案2和跳动图案5常适用于无线链路状况一般的UE(如距离网络设备适中)，跳动图案3和跳动图案6常适用于无线链路状况比较差(如距离网络设备远)、或者前一次随机接入失败的用户。In the bounce patterns shown in Figure 13A and Figure 13B, bounce patterns 1 and 4 are often suitable for UEs with good wireless link conditions (such as being close to the network device), and bounce patterns 2 and 5 are often suitable for wireless links. For UEs with average wireless link conditions (such as being moderately far from the network device), Bounce Pattern 3 and Bounce Pattern 6 are often suitable for users with poor wireless link conditions (such as being far away from the network device), or users whose previous random access failed.
在另外的实施例中，图13A中的跳动图案2和跳动图案3也可以被用来支持UE的发送波束扫描。例如在跳动图案2(UE2)中，在时间t1沿着UE的第一个发送波束的方向发送序列2；在时间t2沿着UE的第二个发送波束方向发送序列3。再例如跳动图案3(UE3)中，在时间t1～t2沿着UE的第一个发送波束方向发送序列4和序列5；在时间t5～t6沿着UE的第二个发送波束方向发送序列6和序列7。如果网络设备已经确定了最佳的接收波束，在网络设备在该最佳的接收波束方向接收信号。如果网络设备没有确定最佳的接收波束，假如网络设备的接收波束有两个，则网络设备按照图13A所示的波束扫描结构来接收信号。在本发明实施例中，子前导的结构如图5所示，CP实际上也是一种序列，GT是不发送数据的保护时间，因此，子前导实际上也可被认为是序列的一种，在图13A到图18C中出现的序列均是指子前导。In other embodiments, the hopping pattern 2 and the hopping pattern 3 in FIG. 13A can also be used to support the UE's transmit beam scanning. For example, in hop pattern 2 (UE2), sequence 2 is sent along the direction of the first transmit beam of the UE at time t1; sequence 3 is sent along the direction of the second transmit beam of the UE at time t2. For another example, in hopping pattern 3 (UE3), sequence 4 and sequence 5 are sent along the first transmit beam direction of the UE at time t1 to t2; sequence 6 is sent along the second transmit beam direction of the UE at time t5 to t6. and sequence 7. If the network device has determined the best receiving beam, the network device receives the signal in the direction of the best receiving beam. If the network device does not determine the best receiving beam, and if the network device has two receiving beams, the network device receives the signal according to the beam scanning structure shown in Figure 13A. In the embodiment of the present invention, the structure of the sub-preamble is shown in Figure 5. CP is actually a kind of sequence, and GT is the guard time for not sending data. Therefore, the sub-preamble can actually be considered as a kind of sequence. The sequences appearing in Figures 13A to 18C are all sub-preambles.
在另外的实施例中，图13B中的跳动图案5和跳动图案6也可以被用来支持UE的发送波束扫描。例如跳动图案5(UE5)中，在时间t1和t3沿着UE的第一个发送波束的方向发送序列10和序列12；在时间t2和t4沿着UE的第二个发送波束的方向发送序列11和序列13。再例如跳动图案6(UE6)中，在时间t1～t4沿着UE的第一个发送波束的方向发送序列14-17；在时间t5～t8沿着UE的第二个发送波束的方向发送序列18-21。再例如跳动图案6(UE6)中，在时间t1,t3,t5,t7沿着UE的第一个发送波束方向发送序列14,16,18,和19；在时间t2,t4,t6,t8沿着UE的第二个发送波束方向发送序列15,17,19,和21。In other embodiments, the hopping pattern 5 and the hopping pattern 6 in FIG. 13B can also be used to support the UE's transmit beam scanning. For example, in hop pattern 5 (UE5), sequence 10 and sequence 12 are sent along the direction of the UE's first transmit beam at times t1 and t3; sequences are sent along the direction of the UE's second transmit beam at times t2 and t4. 11 and sequence 13. For another example, in hopping pattern 6 (UE6), sequences 14-17 are sent along the direction of the UE's first transmission beam at times t1 to t4; sequences 14-17 are sent along the direction of the UE's second transmission beam at times t5 to t8. 18-21. For another example, in jumping pattern 6 (UE6), sequences 14, 16, 18, and 19 are sent along the first transmit beam direction of the UE at times t1, t3, t5, and t7; at times t2, t4, t6, and t8, Sequences 15, 17, 19, and 21 are sent in the direction of the UE's second transmit beam.
在图13C中，一个UE可以采用两个跳动图案生成两个前导以进行随机接入。例如，可以在第一发送波束上发送根据跳动图案7生成的前导，可以在第二发送波束发送根据跳动图案8生成的前导。又例如，可以在第一发送波束上发送根据跳动图案9生成的前导，可以在第二发送波束发送根据跳动图案10生成的前导。在另一个实施中，UE可以在同一个发送波束上发送根据跳动图案7生成的前导和根据跳动图案8生成的前导，该发送方式可以增强网络设备成功检测到UE发送的前导的概率。In Figure 13C, one UE can use two hopping patterns to generate two preambles for random access. For example, the preamble generated based on the jitter pattern 7 may be transmitted on the first transmission beam, and the preamble generated based on the jitter pattern 8 may be transmitted on the second transmission beam. For another example, the preamble generated according to the jitter pattern 9 may be transmitted on the first transmission beam, and the preamble generated according to the jitter pattern 10 may be transmitted on the second transmission beam. In another implementation, the UE may send the preamble generated according to the hopping pattern 7 and the preamble generated according to the hopping pattern 8 on the same transmission beam. This sending method may enhance the probability that the network device successfully detects the preamble sent by the UE.
在上述实施例中，各个UE使用的跳动图案，可以是由网络设备指定，也可以是UE与网络设备预先约定的，还可以是由UE在网络设备指定的范围内根据某个规则选择(例如随机选择，或者根据接收信号能量选择)。网络设备知道UE所有可能采用的跳动图案的信息。In the above embodiments, the beating pattern used by each UE may be specified by the network device, or may be pre-agreed between the UE and the network device, or may be selected by the UE according to a certain rule within the range specified by the network device (for example, Randomly selected, or selected based on received signal energy). The network device knows information about all possible bounce patterns used by the UE.
在进行网络设备的接收波束扫描的情况下，当采用图13A、图13B和图13C所示跳动图案中任意一种生成图11所示结构的信号时，网络设备收到的信号的结构如图12所示，其收到的四个前导分别位于两个波束内。网络设备在各个波束内，对接收到的各个前导信号检测，分别检测其中的序列。In the case of receiving beam scanning of the network device, when any one of the jumping patterns shown in Figure 13A, Figure 13B and Figure 13C is used to generate a signal with the structure shown in Figure 11, the structure of the signal received by the network device is as shown in As shown in Figure 12, the four preambles it received are located in two beams respectively. The network equipment detects each received preamble signal in each beam and detects the sequence therein.
假设图13A的3个UE同时发送前，网络设备对接收到的前导进行检测时可能出现的一种序列检测结果为：Assume that before the three UEs in Figure 13A transmit at the same time, a sequence detection result that may occur when the network device detects the received preamble is:
1)在t1接收的前导信号中，分别检测出序列1，序列2，序列4；1) In the preamble signal received by t1, sequence 1, sequence 2, and sequence 4 are respectively detected;
2)在t2接收的前导信号中，检测出序列3，序列5；2) In the preamble signal received at t2, sequence 3 and sequence 5 are detected;
3)在t5接收的前导信号中，检测出序列6；3) In the preamble signal received at t5, sequence 6 is detected;
4)在t6接收的前导信号中，检测出序列7；4) In the preamble signal received by t6, sequence 7 is detected;
5)其它时间未检测出发送序列。5) No transmission sequence is detected at other times.
在进行以上序列检测时，序列2～3，或者序列4～7可以进行联合检测。根据以上检测结果，网络设备根据图13A所示跳动图案，可以判断出有三个UE发送了前导。When performing the above sequence detection, sequences 2 to 3 or sequences 4 to 7 can be jointly detected. Based on the above detection results, the network device can determine that three UEs have sent preambles based on the jumping pattern shown in Figure 13A.
以序列2和序列3的联合检测为例，对本发明实施例的联合检测进行说明：Taking the joint detection of sequence 2 and sequence 3 as an example, the joint detection according to the embodiment of the present invention will be described:
1)网络设备在时间t1内的接收信号中检测序列2，得到信号y2；在时间t2内的接收信号中检测序列3，得到信号y3；1) The network device detects sequence 2 in the received signal at time t1 and obtains signal y2; detects sequence 3 in the received signal at time t2 and obtains signal y3;
2)将y2和y3的能量合并，与预设的门限值比较，如果大于门限值，则认为发送了序列2和序列3。2) Combine the energy of y2 and y3 and compare it with the preset threshold value. If it is greater than the threshold value, it is considered that sequence 2 and sequence 3 have been sent.
进一步的，本发明实施例中的每个跳动图案指定了用于子前导的至少一个特征序列，该特征序列只会出现在一个特定的跳动图案中，不会出现在其它跳动图案中，因此，网络设备只要检测到该特征序列，就可以认为有UE采用了该特征序列标识的唯一跳动图案发送前导。例如，在图13A中，序列1是跳动图案1的特征序列，序列2和序列3是跳动图案2的特征序列，序列6和序列7是跳动图案3的特征序列。Furthermore, each beat pattern in the embodiment of the present invention specifies at least one feature sequence for the sub-preamble. This feature sequence will only appear in a specific beat pattern and will not appear in other beat patterns. Therefore, As long as the network device detects the characteristic sequence, it can consider that a UE has used the unique beating pattern identified by the characteristic sequence to send a preamble. For example, in FIG. 13A , sequence 1 is the characteristic sequence of the beating pattern 1 , sequence 2 and sequence 3 are the characteristic sequences of the beating pattern 2 , and sequence 6 and sequence 7 are the characteristic sequences of the beating pattern 3 .
进一步的，在本发明实施例中，网络设备知道各个UE发送时可能采取的跳动图案。因此，网络设备在接收检测的时候：Furthermore, in this embodiment of the present invention, the network device knows the possible beating patterns adopted by each UE when transmitting. Therefore, when a network device receives a detection:
1)在t1位置检测到序列1时，就判断出UE在发送前导信号时采取了跳动图案11) When sequence 1 is detected at the t1 position, it is judged that the UE adopts jumping pattern 1 when sending the preamble signal.
2)在t1位置检测到序列2和在t2位置检测到序列3，就认为有UE采用了跳动图案2来发送前导信号；2) If sequence 2 is detected at the t1 position and sequence 3 is detected at the t2 position, it is considered that a UE uses the jumping pattern 2 to send the preamble signal;
3)在t1和t2位置分别检测到序列4和序列5，并且在t5和t6位置分别检测到序列6和7，就认为有UE采用了跳动图案3来发送前导信号。3) If sequence 4 and sequence 5 are detected at positions t1 and t2 respectively, and sequences 6 and 7 are detected at positions t5 and t6 respectively, it is considered that a UE has used hop pattern 3 to send the preamble signal.
4)总共检测出三个跳动图案，可以认为有三个UE发送了波束。4) A total of three beating patterns are detected, and it can be considered that three UEs have sent beams.
假设图13B中3个UE都在同时发送了前导，并且每个UE只有一个发送波束的情况下，网络设备对接收到的前导信号进行检测时可能出现的一种序列检测结果为：Assuming that the three UEs in Figure 13B all send preambles at the same time, and each UE has only one transmission beam, a sequence detection result that may occur when the network device detects the received preamble signal is:
1)在t3接收的前导信号中，检测出序列9，序列12，序列16；1) In the preamble signal received at t3, sequence 9, sequence 12, and sequence 16 are detected;
2)在t4接收的前导信号中，分别检测出序列13，序列17；2) In the preamble signal received at t4, sequence 13 and sequence 17 are respectively detected;
3)在t7接收的前导信号中，检测出序列20；3) In the preamble signal received at t7, sequence 20 is detected;
4)在t8接收的前导信号中，检测出序列21；4) In the preamble signal received by t8, sequence 21 is detected;
5)其它时间未检测出发送序列。5) No transmission sequence is detected at other times.
以上序列检测时，序列12～13，或者序列16～17、序列20～21可以进行联合检测。根据以上检测结果，以及网络设备根据图13B所示图案，网络设备可以判断出有三个UE发送了前导信号。由于上述被检测出的序列都是位于时间t3、t4、t7、和t8处的序列，而在其他时间上检测到序列，且由图11可知，时间t3、t4、t7、和t8对应的是网络设备的接收波束2的扫描时间，故根据上述检测结果可以知道网络设备的最佳接收波束是接收波束2。When detecting the above sequences, sequences 12 to 13, or sequences 16 to 17, and sequences 20 to 21 can be jointly detected. Based on the above detection results and the network device according to the pattern shown in Figure 13B, the network device can determine that three UEs have sent preamble signals. Since the above detected sequences are all sequences located at times t3, t4, t7, and t8, and sequences are detected at other times, and as shown in Figure 11, times t3, t4, t7, and t8 correspond to The scanning time of the network device's receiving beam 2, so based on the above detection results, it can be known that the best receiving beam of the network device is the receiving beam 2.
假设图13C中2个UE同时发送前导，并且每个UE的跳动图案分别沿不同的发送波束方向的情况下(跳动图案7和跳动图案9对应发送波束1，跳动图案8和跳动图案10对应发送波束2)，网络设备对接收到的前导信号进行检测时可能出现的一种序列检测结果为：Assume that two UEs in Figure 13C send preambles at the same time, and the beating patterns of each UE are along different transmit beam directions (beat patterns 7 and 9 correspond to transmit beam 1, and beat patterns 8 and 10 correspond to transmit beams). Beam 2), a sequence detection result that may occur when the network device detects the received preamble signal is:
1)在t1接收的前导信号中，分别检测出序列26；1) In the preamble signal received by t1, sequence 26 is detected respectively;
2)在t3接收的前导信号中，检测出序列23；2) In the preamble signal received at t3, sequence 23 is detected;
3)在t5接收的前导信号中，检测出序列28；3) In the preamble signal received at t5, sequence 28 is detected;
4)其它时间未检测出发送序列。4) The sending sequence is not detected at other times.
以上序列检测时，序列26和序列28可以进行联合检测。网络检测设备根据以上检测结果，以及图13C所示的跳动图案，网络设备可以判断出有两个UE发送了前导，发送序列23的UE的最佳发送波束为发送波束1、网络设备的最佳接收波束是2；发送序列26和序列28的UE最佳发送波束为1、网络设备的最佳接收波束是接收波束2。When detecting the above sequences, sequence 26 and sequence 28 can be jointly detected. Based on the above detection results and the beating pattern shown in Figure 13C, the network detection device can determine that two UEs have sent preambles, and the best sending beam of the UE sending sequence 23 is sending beam 1. The best sending beam of the network device The receiving beam is 2; the optimal transmitting beam of the UE that transmits sequence 26 and sequence 28 is 1, and the optimal receiving beam of the network device is receiving beam 2.
图14A、图14B和图14C示出了跳动图案的另外一些实例，这些跳动图案和网络设备的接收波束有关。具体地，这些跳动图案可以与RACH在网络设备进行接收波束扫描时所呈现出的结构有关。Figures 14A, 14B, and 14C illustrate additional examples of jitter patterns associated with receive beams of network devices. Specifically, these beating patterns may be related to the structure presented by the RACH when the network device performs receiving beam scanning.
UE获取网络设备的接收波束的扫描信息，然后选择跳动图案。The UE obtains the scanning information of the receiving beam of the network device, and then selects the beating pattern.
同一波束在其各个扫描时间内接收到的信号对应同一种跳动图案，不同接收波束接收到的信号可以对应完全相同的跳动图案。例如图14A所示，跳动图案1～3被用于只在网络设备的一个接收波束对应的扫描时间中发送前导；图14B和图14C所示，跳动图案4～15被用于在网络设备的多个接收波束对应的扫描时间内发送前导。The signals received by the same beam in each scanning time correspond to the same beating pattern, and the signals received by different receiving beams can correspond to the exact same beating pattern. For example, as shown in Figure 14A, bounce patterns 1 to 3 are used to send preambles only in the scanning time corresponding to one receiving beam of the network device; as shown in Figure 14B and 14C, bounce patterns 4 to 15 are used to send preambles in the scanning time of the network device. Preambles are sent within the scanning time corresponding to multiple receive beams.
图14A所示的跳动图案可以适用于已经确定发送、接收波束的UE的场景，UE可以采用该图中所示的图案生成前导，用来发送调度请求，切换请求等作用。The jumping pattern shown in Figure 14A can be applied to the scenario where the UE has determined to send and receive beams. The UE can use the pattern shown in the figure to generate a preamble, which is used to send scheduling requests, handover requests and other functions.
图14B和图14C可以适用于没有确定UE的最佳发送波束或者网络设备的接收波束的场景，UE可以采用该图所示的图案生成前导，以在随机接入过程中支持波束扫描。例如，UE在进行第一次上行同步UE时，或者UE与网络设备之间的上行链路发生链路中断(l inkfai lure)时，UE和网络设备就需要进行波束扫描以确定UE的最佳发送波束和网络设备的最佳接收波束，此时就可以采用图14B和图14C所示图案中任意一种跳动图案来生成前导，该前导可以被用来确定UE的最佳发送波束和网络设备的最佳接收波束。Figures 14B and 14C can be applied to scenarios where the optimal transmit beam of the UE or the receive beam of the network device has not been determined. The UE can generate a preamble using the pattern shown in the figure to support beam scanning during the random access process. For example, when the UE synchronizes the UE for the first time in uplink, or when the uplink between the UE and the network device is interrupted (linkfai lure), the UE and the network device need to perform beam scanning to determine the best position of the UE. At this time, any of the beating patterns shown in Figure 14B and Figure 14C can be used to generate a preamble. This preamble can be used to determine the best transmission beam and network equipment for the UE. the best receiving beam.
在图14A和图14B所示的跳动图案中，跳动图案1、跳动图案4、以及跳动图案5常适用于无线链路状况好的用户(如距离网络设备近)，跳动图案2、跳动图案6、以及跳动图案7常适用于无线链路状况一般的用户(如距离网络设备适中)，跳动图案3、跳动图案8、以及跳动图案9常适用于无线链路状况比较差(如距离网络设备远)、或者前一次随机接入失败的用户。Among the bounce patterns shown in Figure 14A and Figure 14B, bounce pattern 1, bounce pattern 4, and bounce pattern 5 are often suitable for users with good wireless link conditions (such as those who are close to the network device). Bounce pattern 2, bounce pattern 6 , and Bounce Pattern 7 are often suitable for users with average wireless link conditions (such as moderate distance from network devices). Bounce Pattern 3, Bounce Pattern 8, and Bounce Pattern 9 are often suitable for users with poor wireless link conditions (such as far from network devices). ), or users who failed in the previous random access.
在另外的实施例中，图14A所示的跳动图案2和跳动图案3也可以被用来支持UE的发送波束扫描。例如UE2中，在时间t1沿着第一个发送波束方向发送序列2；在时间t2沿着第二个发送波束方向发送序列3。再例如UE3中，在时间t1～t2沿着第一个发送波束方向发送序列4和序列5；在时间t5～t6沿着第二个发送波束方向发送序列6和序列7。In other embodiments, the hopping pattern 2 and the hopping pattern 3 shown in FIG. 14A may also be used to support the UE's transmit beam scanning. For example, in UE2, sequence 2 is sent along the first transmit beam direction at time t1; sequence 3 is sent along the second transmit beam direction at time t2. For another example, UE3 transmits sequence 4 and sequence 5 along the first transmission beam direction at time t1 to t2; and transmits sequence 6 and sequence 7 along the second transmission beam direction at time t5 to t6.
在另外的实施例中，图14B所示的跳动图案6-9也可以被用来支持UE的发送波束扫描。例如UE5的跳动图案6和7，在时间t1和t3沿着第一个发送波束方向发送序列10和序列12；在时间t2和t4沿着第二个发送波束方向发送序列11和序列13。再例如UE6的跳动图案8和9，在时间t1～t4沿着第一个发送波束方向发送序列14-17；在时间t5～t6沿着第二个发送波束方向发送序列18-21。再例如跳动图案6(UE6)中，在时间t1,t3,t5,t7沿着第一个发送波束方向发送序列14,16,18,和29；在时间t2,t4,t6,t8沿着第二个发送波束方向发送序列15,17,19和21。In other embodiments, the jumping patterns 6-9 shown in Figure 14B can also be used to support the UE's transmit beam scanning. For example, the hopping patterns 6 and 7 of UE5 send sequence 10 and sequence 12 along the first transmit beam direction at times t1 and t3; and transmit sequence 11 and sequence 13 along the second transmit beam direction at times t2 and t4. For another example, the hopping patterns 8 and 9 of UE6 send sequences 14-17 along the first transmit beam direction at times t1 to t4; and transmit sequences 18-21 along the second transmit beam direction at times t5 to t6. For another example, in beating pattern 6 (UE6), sequences 14, 16, 18, and 29 are transmitted along the first transmit beam direction at times t1, t3, t5, and t7; at times t2, t4, t6, and t8, sequences 14, 16, 18, and 29 are transmitted along the The two transmit beam directions transmit sequences 15, 17, 19 and 21.
在另外的实施例中，图14C所示的跳动图案中，一个UE可以采用两个跳动图案生成两个前导以进行随机接入。例如UE7可以在第一发送波束上发送根据跳动图案8和10生成的前导，可以在第二发送波束发送根据跳动图案9和11生成的前导。又例如，UE8可以在第一发送波束上发送根据跳动图案12和14生成的前导，可以在第二发送波束发送根据跳动图案13和15生成的前导。在另一个实施中，UE可以在同一个发送波束上发送根据跳动图案8-11生成的前导和根据跳动图案8生成的前导，该发送方式可以增强网络设备成功检测到UE发送的前导的概率。In other embodiments, in the hopping pattern shown in Figure 14C, a UE may use two hopping patterns to generate two preambles for random access. For example, UE7 may send preambles generated based on the hopping patterns 8 and 10 on the first transmission beam, and may send preambles generated based on the hopping patterns 9 and 11 on the second transmission beam. For another example, UE8 may send the preamble generated according to the beating patterns 12 and 14 on the first sending beam, and may send the preamble generated according to the beating patterns 13 and 15 on the second sending beam. In another implementation, the UE may send the preamble generated according to the hopping pattern 8-11 and the preamble generated according to the hopping pattern 8 on the same transmission beam. This sending method may enhance the probability that the network device successfully detects the preamble sent by the UE.
在网络设备的接收波束需要扫描的情况下，当采用图14A、图14B和图14C所示跳动图案中任意一种生成图11所示结构的信号时，网络设备收到的信号的结构如图12所示，其收到的四个前导分别位于在两个波束方向所接收到的信号中。网络设备在各个波束方向，对接收到的各个前导进行检测，分别检测其中的序列。When the receiving beam of the network device needs to be scanned, when any one of the jumping patterns shown in Figure 14A, Figure 14B and Figure 14C is used to generate the signal with the structure shown in Figure 11, the structure of the signal received by the network device is as shown in Figure 11 As shown in Figure 12, the four preambles it received are located in the signals received in the two beam directions. The network equipment detects each received preamble in each beam direction and detects the sequences in it respectively.
图14A所示的3个UE都同时发送前导，网络设备对接收到的前导进行检测时可能出现的一种序列检测结果为：The three UEs shown in Figure 14A all send preambles at the same time. When the network device detects the received preambles, a possible sequence detection result is:
1)在t1接收的前导信号中，分别检测出序列1，序列2，序列4；1) In the preamble signal received by t1, sequence 1, sequence 2, and sequence 4 are respectively detected;
2)在t2接收的前导信号中，检测出序列3，序列5；2) In the preamble signal received at t2, sequence 3 and sequence 5 are detected;
3)在t5接收的前导信号中，检测出序列6；3) In the preamble signal received at t5, sequence 6 is detected;
4)在t6接收的前导信号中，检测出序列7；4) In the preamble signal received by t6, sequence 7 is detected;
5)其它时间未检测出发送序列。5) No transmission sequence is detected at other times.
以上序列检测时，序列2～3，或者序列4～7可以进行联合检测。网络设备根据以上检测结果，和图14A所示的跳动图案，网络设备可以判断出有三个UE发送了前导。When detecting the above sequences, sequences 2 to 3 or sequences 4 to 7 can be jointly detected. Based on the above detection results and the beating pattern shown in Figure 14A, the network device can determine that three UEs have sent preambles.
图14B所示的3个UE同时发送前导，并且每个UE只有一个发送波束方向的情况下，网络设备对接收到的前导信号进行检测时可能出现的一种序列检测结果为：In the case where three UEs send preambles at the same time as shown in Figure 14B, and each UE has only one transmission beam direction, a sequence detection result that may occur when the network device detects the received preamble signal is:
1)在t3接收的前导信号中，检测出序列9，序列12，序列16；1) In the preamble signal received at t3, sequence 9, sequence 12, and sequence 16 are detected;
2)在t4接收的前导信号中，分别检测出序列13，序列17；2) In the preamble signal received at t4, sequence 13 and sequence 17 are respectively detected;
3)在t7接收的前导信号中，检测出序列20；3) In the preamble signal received at t7, sequence 20 is detected;
4)在t8接收的前导信号中，检测出序列21。4) In the preamble signal received at t8, sequence 21 is detected.
5)其它时间未检测出发送序列。5) No transmission sequence is detected at other times.
注意以上序列检测时，序列12～13，或者序列16～17、序列20～21可以进行联合检测。网络设备根据以上检测结果，图14B所示跳动图案，可以判断出有三个UE发送了前导，最佳接收波束都是2。Note that when detecting the above sequences, sequences 12 to 13, or sequences 16 to 17, and sequences 20 to 21 can be jointly detected. Based on the above detection results and the beating pattern shown in Figure 14B, the network equipment can determine that three UEs have sent preambles, and the best receiving beams are all 2.
图14C中2个UE同时发送前导，并且根据不同的跳动图案生成的前导分别沿不同的发送波束方向发送的情况下(跳动图案8，跳动图案10，跳动图案12，跳动图案14对应发送波束1，跳动图案9，跳动图案11，跳动图案13，跳动图案15对应发送波束2)，网络设备对接收到的前导信号进行检测时可能出现的一种序列检测结果为：In Figure 14C, two UEs send preambles at the same time, and the preambles generated according to different beating patterns are sent in different transmit beam directions (beat pattern 8, beat pattern 10, beat pattern 12, and beat pattern 14 correspond to transmit beam 1 , Bounce pattern 9, Bounce pattern 11, Bounce pattern 13, Bounce pattern 15 correspond to the transmission beam 2), a sequence detection result that may occur when the network device detects the received preamble signal is:
1)在t1接收的前导信号中，分别检测出序列26；1) In the preamble signal received by t1, sequence 26 is detected respectively;
2)在t3接收的前导信号中，检测出序列23；2) In the preamble signal received at t3, sequence 23 is detected;
3)在t5接收的前导信号中，检测出序列28；3) In the preamble signal received at t5, sequence 28 is detected;
4)其它时间未检测出发送序列。4) The sending sequence is not detected at other times.
以上序列检测时，序列26和序列28可以进行联合检测。网络设备根据以上检测结果，以及图14C所示跳动图案，网络设备可以判断出有两个UE发送了前导，发送序列23的UE的最佳发送波束为1、最佳接收波束是2；发送序列26和序列28的UE的最佳发送波束为1、最佳接收波束是2。When detecting the above sequences, sequence 26 and sequence 28 can be jointly detected. Based on the above detection results and the beating pattern shown in Figure 14C, the network device can determine that two UEs have sent preambles. The best sending beam of the UE sending sequence 23 is 1 and the best receiving beam is 2; the sending sequence 26 and 28, the best transmit beam of the UE is 1 and the best receive beam is 2.
图15示出了一个多子带RACH的结构一个示例。在本实施例中，RACH有两个子带，每个子带的频域宽度为72个子载波，子载波间隔是60KHz；在RACH的时长内UE发送有4个前导，这4个前导分布两个子带上，每个子带上有两个前导，每个前导的时长等于两个子前导的时长。各个前导之间在时间上可以连续，也可以不连续，但是互相不交叠。Figure 15 shows an example of the structure of a multi-subband RACH. In this embodiment, RACH has two sub-bands, the frequency domain width of each sub-band is 72 sub-carriers, and the sub-carrier spacing is 60 KHz; within the duration of RACH, the UE sends 4 preambles, and these 4 preambles are distributed in two sub-bands On, each sub-band has two preambles, and the duration of each preamble is equal to the duration of the two sub-preambles. Each leader can be continuous or discontinuous in time, but it does not overlap with each other.
针对图15所示结构的信号，网络设备在进行接收波束扫描时接收到的信号的结构如图16所示。在本实施例中，网络设备在两个接收波束上进行扫描，在每个接收波束的一个扫描时间内上均接收到位于两个子带上的前导。For the signal with the structure shown in Figure 15, the structure of the signal received by the network device when scanning the receiving beam is as shown in Figure 16. In this embodiment, the network device scans on two receiving beams, and receives preambles located on two sub-bands within one scanning time of each receiving beam.
UE根据接收到的下行指示信息，选择跳动图案。例如图17A所示，跳动图案1～2被用于只在一个接收波束方向发送前导；图17B所示，跳动图案3～4被用于在多个接收波束内发送前导；图17C所示，跳动图案5～6被用于在多个发送波束、接收波束内发送前导。The UE selects the jitter pattern according to the received downlink indication information. For example, as shown in Figure 17A, the jumping patterns 1 to 2 are used to send preambles in only one receiving beam direction; as shown in Figure 17B, the jumping patterns 3 to 4 are used to send preambles in multiple receiving beams; as shown in Figure 17C, Bounce patterns 5 to 6 are used to transmit preambles in multiple transmit beams and receive beams.
图17A可以适用于已经确定UE的最佳发送波束、网络设备的最佳接收波束场景，UE可以采用该图中所示的图案生成前导，用来发送调度请求，切换请求等。Figure 17A can be applied to a scenario where the best transmit beam of the UE and the best receive beam of the network device have been determined. The UE can use the pattern shown in the figure to generate a preamble to send scheduling requests, handover requests, etc.
图17B和图17C可以适用于没有确定UE的最佳发送波束和/或网络设备的最佳接收波束的场景，UE可以采用该图所示的图案生成前导，以在随机接入过程中支持波束扫描。例如，UE在进行第一次上行同步UE时，或者UE与网络设备之间的上行链路发生链路中断(link fai lure)时，UE和网络设备就需要进行波束扫描以确定UE的最佳发送波束和网络设备的最佳接收波束，此时就可以采用图17B和图17C所示图案中任意一种跳动图案来生成前导，该前导可以被用来确定UE的最佳发送波束和网络设备的最佳接收波束。Figures 17B and 17C can be applied to scenarios where the best transmit beam of the UE and/or the best receive beam of the network device has not been determined. The UE can generate a preamble using the pattern shown in this figure to support the beam during the random access process. scanning. For example, when the UE performs uplink synchronization for the first time, or when a link failure occurs in the uplink between the UE and the network device, the UE and the network device need to perform beam scanning to determine the best path for the UE. At this time, any of the beating patterns shown in Figure 17B and Figure 17C can be used to generate a preamble. This preamble can be used to determine the best transmission beam and network equipment for the UE. the best receiving beam.
在另外的实施例中，图17A所示的跳动图案2也可以被用来支持UE的发送波束扫描。例如跳动图案2(UE2)中，在时间t1沿着第一个发送波束方向发送序列2；在时间t2沿着第二个发送波束方向发送序列3。In other embodiments, the jumping pattern 2 shown in FIG. 17A can also be used to support the UE's transmit beam scanning. For example, in hopping pattern 2 (UE2), sequence 2 is sent along the first transmit beam direction at time t1; sequence 3 is sent along the second transmit beam direction at time t2.
在另外的实施例中，图17B所示的跳动图案3和跳动图案4也可以被用来支持UE的发送波束扫描。例如跳动图案3(UE3)中，在时间t1和t3沿着第一个发送波束方向发送序列4和序列6；在时间t2和t4沿着第二个发送波束方向发送序列5和序列7。In other embodiments, the hopping pattern 3 and the hopping pattern 4 shown in FIG. 17B may also be used to support the UE's transmit beam scanning. For example, in beating pattern 3 (UE3), sequence 4 and sequence 6 are sent along the first transmit beam direction at times t1 and t3; sequence 5 and sequence 7 are sent along the second transmit beam direction at times t2 and t4.
在另外的实施例中，图17C所示的两个跳动图案可以被一个UE采用来生成前导信号以进行随机接入。例如在发送波束方向1上发送根据跳动图案5生成的前导，在发送波束方向上发送根据跳动图案6生成的前导；或者在同一个发送波束方向上发送根据跳动图案5和跳动图案6生成的前导。In other embodiments, the two hopping patterns shown in Figure 17C can be adopted by a UE to generate a preamble signal for random access. For example, the preamble generated according to the beat pattern 5 is sent in the transmit beam direction 1, and the preamble generated according to the beat pattern 6 is sent in the transmit beam direction; or the preamble generated according to the beat pattern 5 and 6 is sent in the same transmit beam direction. .
在网络设备的接收波束需要扫描的情况下，针对根据图17A、图17B、图17C所示的跳动图案生成的随机接入信号，网络设备接收到的2个前导，4个子前导信号，分别位于在两个接收波束方向接收到的信号中。在每个接收波束方向，均收到两个子前导(或者前导)。在各个波束内，对接收到的各个前导进行检测，分别检测其中的序列。When the receiving beam of the network device needs to be scanned, for the random access signal generated according to the beating pattern shown in Figure 17A, Figure 17B, and Figure 17C, the two preambles and four sub-preamble signals received by the network device are located respectively. in the received signals in both receive beam directions. In each receive beam direction, two sub-preambles (or preambles) are received. In each beam, each received preamble is detected, and the sequences therein are detected respectively.
图17A的2个UE分别按照图示跳动图案发送前导，网络设备对接收到的前导进行检测时可能出现的一种序列检测结果为：The two UEs in Figure 17A respectively send preambles according to the jumping pattern shown in the figure. When the network device detects the received preambles, a possible sequence detection result is:
1)在t1接收的前导信号中，分别检测出序列1，序列2；1) In the preamble signal received by t1, sequence 1 and sequence 2 are detected respectively;
2)在t2接收的前导信号中，检测出序列3；2) In the preamble signal received by t2, sequence 3 is detected;
3)其它时间未检测出发送序列。3) The sending sequence is not detected at other times.
以上序列检测时，序列2和序列3可以进行联合检测。网络设备根据以上检测结果，以及图17A所示的跳动图案，网络设备可以判断出有两个UE发送了前导，最佳接收波束为1。When detecting the above sequences, sequence 2 and sequence 3 can be jointly detected. Based on the above detection results and the beating pattern shown in Figure 17A, the network device can determine that two UEs have sent preambles, and the best receiving beam is 1.
图17B中2个UE分别按照图示跳动图案发送前导信号，并且每个UE只有一个发送波束方向的情况下，网络设备对接收到的前导信号进行检测时可能出现的一种序列检测结果为：In Figure 17B, two UEs respectively transmit preamble signals according to the illustrated jumping pattern, and each UE has only one transmission beam direction. When the network device detects the received preamble signal, a possible sequence detection result is:

以上序列检测时，序列4～5，或者序列10～11、序列14～15可以进行联合检测。网络设备根据以上检测结果，以及图17B所示的跳动图案，网络设备可以判断出有三个UE发送了前导，序列4～5的最佳接收波束分别是接收波束1，序列10～11，序列14～15的最佳接收波束是接收波束2。When detecting the above sequences, sequences 4 to 5, or sequences 10 to 11, and sequences 14 to 15 can be jointly detected. Based on the above detection results and the beating pattern shown in Figure 17B, the network device can determine that three UEs have sent preambles. The best receiving beams for sequences 4 to 5 are receiving beam 1, sequences 10 to 11, and sequence 14 respectively. The best receive beam for ~15 is receive beam 2.
图17C中1个UE按照图示跳动图案发送前导，并且根据两个跳动图案生成的前导被分别沿不同的发送波束方向发送的情况下(跳动图案5对应发送波束1，跳动图案6对应发送波束2)，网络设备对接收到的前导信号进行检测时可能出现的一种序列检测结果为：In Figure 17C, one UE sends a preamble according to the illustrated hopping pattern, and the preambles generated according to the two hopping patterns are sent in different transmit beam directions (bounce pattern 5 corresponds to transmit beam 1, and hopping pattern 6 corresponds to transmit beam 2), a sequence detection result that may occur when the network device detects the received preamble signal is:
1)在t2接收的前导信号中，检测出序列20和序列22；1) In the preamble signal received at t2, sequence 20 and sequence 22 are detected;
2)其它时间未检测出发送序列。2) The sending sequence is not detected at other times.
注意以上序列检测时，序列20和序列22可以进行联合检测。网络设备根据以上检测结果，以及图17B所示的跳动图案，网络设备可以判断出有1个UE发送了前导，序列20和序列22的UE最佳发送波束为2、最佳接收波束是1。Note that during the above sequence detection, sequence 20 and sequence 22 can be jointly detected. Based on the above detection results and the beating pattern shown in Figure 17B, the network device can determine that one UE has sent a preamble. The best sending beam for the UE in sequence 20 and sequence 22 is 2, and the best receiving beam is 1.
图18A、图18B和图18C示出了跳动图案的另外一些实例，这些跳动图案和网络设备的接收波束有关。具体地，这些跳动图案可以与RACH在网络设备进行接收波束扫描时所呈现出的结构有关。Figures 18A, 18B, and 18C illustrate additional examples of jitter patterns associated with receive beams of network devices. Specifically, these beating patterns may be related to the structure presented by the RACH when the network device performs receiving beam scanning.

图18B和图18C可以适用于没有确定UE的最佳发送波束和/或网络设备的接收波束的场景，UE可以采用该图所示的图案生成前导，以在随机接入过程中支持波束扫描。例如，UE在进行第一次上行同步UE时，或者UE与网络设备之间的上行链路发生链路中断(l inkfai lure)时，UE和网络设备就需要进行波束扫描以确定UE的最佳发送波束和网络设备的最佳接收波束，此时就可以采用图18B和图18C所示图案中任意一种跳动图案来生成前导，该前导可以被用来确定UE的最佳发送波束和网络设备的最佳接收波束。Figures 18B and 18C can be applied to scenarios where the optimal transmit beam of the UE and/or the receive beam of the network device has not been determined. The UE can generate a preamble using the pattern shown in the figure to support beam scanning during the random access process. For example, when the UE synchronizes the UE for the first time in uplink, or when the uplink between the UE and the network device is interrupted (linkfai lure), the UE and the network device need to perform beam scanning to determine the best position of the UE. At this time, any of the beating patterns shown in Figure 18B and Figure 18C can be used to generate a preamble. This preamble can be used to determine the best transmission beam and network equipment for the UE. the best receiving beam.
在另外的实施例中，图18A所示的跳动图案2也可以被用来支持UE的发送波束扫描。例如跳动图案2(UE2)中，在时间t1沿着第一个发送波束方向发送序列2；时间t2沿着第二个发送波束方向发送序列3。In other embodiments, the jumping pattern 2 shown in FIG. 18A can also be used to support the UE's transmit beam scanning.

在另外的实施例中，在图18B所示的跳动图案3和跳动图案4也可以被用来支持UE的发送波束扫描。例如跳动图案3(UE3)中，在时间t1和t3沿着第一个发送波束方向发送序列4和序列6；在时间t2和t4沿着第二个发送波束方向发送序列5和序列7。In other embodiments, the hopping pattern 3 and the hopping pattern 4 shown in FIG. 18B may also be used to support the UE's transmit beam scanning. For example, in beating pattern 3 (UE3), sequence 4 and sequence 6 are sent along the first transmit beam direction at times t1 and t3; sequence 5 and sequence 7 are sent along the second transmit beam direction at times t2 and t4.

For example, the preamble signals generated according to the beating patterns 7 and 8 are sent in the transmitting beam direction 1, and the preamble signals generated according to the beating patterns 9 and 10 are sent in the transmitting beam direction 2; or the preamble signals generated according to the beating patterns 7-10 are sent in the same transmitting beam direction.

In each receive beam direction, there are 2 received sub-preambles. In each beam, each received sub-preamble is detected, and the sequences therein are detected respectively.
图18A的2个UE分别按照图示的跳动图案发送前导信号，网络设备对接收到的前导信号进行检测时可能出现的一种序列检测结果为：The two UEs in Figure 18A respectively send preamble signals according to the beating pattern shown in the figure. When the network device detects the received preamble signal, a possible sequence detection result is:
1)在t1接收的前导中，分别检测出序列1，序列2；1) In the preamble received by t1, sequence 1 and sequence 2 are detected respectively;
2)在t2接收的前导中，检测出序列3；2) In the preamble received by t2, sequence 3 is detected;
3)其它时间未检测出发送序列。3) The sending sequence is not detected at other times.
以上序列检测时，序列2和序列3可以进行联合检测。网络设备根据以上检测结果，以及图18A所示的跳动图案，可以判断出有两个UE发送了前导，最佳接收波束为1。When detecting the above sequences, sequence 2 and sequence 3 can be jointly detected. Based on the above detection results and the beating pattern shown in Figure 18A, the network device can determine that two UEs have sent preambles, and the best receiving beam is 1.
图18B中2个UE分别按照图示跳动图案发送前导，并且每个UE只有一个发送波束方向的情况下，网络设备对接收到的前导进行检测时可能出现的一种序列检测结果为：In Figure 18B, two UEs respectively send preambles according to the hopping pattern shown in the figure, and each UE has only one transmission beam direction. When the network device detects the received preamble, a possible sequence detection result is:
1)在t1接收的前导中，检测出序列4；1) In the preamble received by t1, sequence 4 is detected;
2)在t2接收的前导中，检测出序列5；2) In the preamble received by t2, sequence 5 is detected;
3)在t3接收的前导中，检测出序列10，序列14；3) In the preamble received by t3, sequence 10 and sequence 14 are detected;
4)在t4接收的前导中，检测出序列11，序列15。4) In the preamble received at t4, sequence 11 and sequence 15 are detected.
以上序列检测时，序列4～5，或者序列10～11、序列14～15可以进行联合检测。网络设备根据以上检测结果，以及图18B所示的跳动图案，判断出有三个UE发送了前导，序列4～5的最佳接收波束分别是接收波束1，序列10～11，序列14～15的最佳接收波束是接收波束2。When detecting the above sequences, sequences 4 to 5, or sequences 10 to 11, and sequences 14 to 15 can be jointly detected. Based on the above detection results and the beating pattern shown in Figure 18B, the network equipment determines that three UEs have sent preambles. The best receiving beams for sequences 4 to 5 are receiving beams 1, 10 to 11, and 14 to 15 respectively. The best receive beam is receive beam 2.
图18C中1个UE按照图示跳动图案发送前导，并且两个跳动图案被同一个UE采用分别沿不同的发送波束方向发送前导的情况下(跳动图案7和跳动图案8对应发送波束1，跳动图案9和跳动图案10对应发送波束2)，可能的一种序列检测结果为：In Figure 18C, a UE sends a preamble according to the illustrated hopping pattern, and two hopping patterns are used by the same UE to send the preamble along different transmission beam directions (beating pattern 7 and hopping pattern 8 correspond to transmitting beam 1, jumping pattern Pattern 9 and beating pattern 10 correspond to transmitting beam 2). A possible sequence detection result is:
1)在t2接收的前导信号中，检测出序列20和序列22；1) In the preamble signal received at t2, sequence 20 and sequence 22 are detected;
2)其它时间未检测出发送序列。2) The sending sequence is not detected at other times.
以上序列检测时，序列20和序列22可以进行联合检测。根据以上检测结果，以及网络设备关于跳动图案的先验信息，网络设备可以判断出有1个UE发送了前导，序列20和序列22的UE最佳发送波束为2、网络设备的最佳接收波束是1。When detecting the above sequences, sequence 20 and sequence 22 can be jointly detected. Based on the above detection results and the network equipment’s prior information about the beating pattern, the network equipment can determine that 1 UE has sent the preamble, and the optimal sending beam of the UE in sequence 20 and sequence 22 is 2, and the optimal receiving beam of the network equipment is it's 1.
