技术领域Technical Field
本申请涉及无线通信领域，尤其涉及一种信号传输方法及装置。The present application relates to the field of wireless communications, and in particular to a signal transmission method and device.
背景技术Background technique
第五代(5th Generation，5G)通信系统中，准共址(Quasi-Co-Location，QCL)可以用来辅助描述接收侧设备的波束赋形及接收流程。具体地，该QCL可以指示一些空间特性参数，如出发角相关参数、到达角相关参数等。其中出发角相关参数可以包括：水平向出发角(Azimuth angle of Departure，AoD)、垂直向出发角(Zenith angle of Departure，ZoD)、水平向出发角角度扩展(Azimuth angle spread of Departure，ASD)、垂直向出发角角度扩展(Zenith angle spread of Departure，ZSD)等。到达角相关参数可以包括：水平向到达角(Azimuth angle of Arrival，AoA)、垂直向到达角(Zenith angle of Arrival，ZoA)、水平向到达角角度扩展(Azimuth angle spread of Arrival，ASA)，垂直向到达角角度扩展(Zenith angle spread of Arrival，ZSA)等。这些空间特性参数描述了参考信号天线端口间的空间信道特性，以辅助接收侧设备的波束赋形或接收处理过程。可选地，QCL还可以包括除上述参数外的其他参数，如信道传输时延、天线增益以及多普勒参数等的指示信息。In the fifth generation (5G) communication system, Quasi-Co-Location (QCL) can be used to assist in describing the beamforming and receiving process of the receiving side device. Specifically, the QCL can indicate some spatial characteristic parameters, such as departure angle related parameters, arrival angle related parameters, etc. The departure angle related parameters may include: horizontal departure angle (Azimuth angle of Departure, AoD), vertical departure angle (Zenith angle of Departure, ZoD), horizontal departure angle spread (Azimuth angle spread of Departure, ASD), vertical departure angle spread (Zenith angle spread of Departure, ZSD), etc. The arrival angle related parameters may include: horizontal arrival angle (Azimuth angle of Arrival, AoA), vertical arrival angle (Zenith angle of Arrival, ZoA), horizontal arrival angle spread (Azimuth angle spread of Arrival, ASA), vertical arrival angle spread (Zenith angle spread of Arrival, ZSA), etc. These spatial characteristic parameters describe the spatial channel characteristics between the reference signal antenna ports to assist the beamforming or receiving processing process of the receiving side device. Optionally, QCL may also include other parameters in addition to the above parameters, such as indication information of channel transmission delay, antenna gain, and Doppler parameters.
现有技术中，终端假定网络设备周期性发送的任意两个同步信号(synchronization signal，SS)或物理广播信道(physical broadcast channel，PBCH)簇内有相同索引号的两个SS/PBCH块对应的天线端口是满足QCL假设的、而位于一个SS/PBCH内不同索引号的两个SS/PBCH块对应的天线端口不满足QCL假设。对于不同索引号的两个SS/PBCH块对应的天线端口也满足QCL假设的情况，需要基站对终端进行指示，但是目前只能指示均匀重复的情况，即一个SS/PBCH簇中，每组SS/PBCH块个数相同，同一组的SS/PBCH块满足QCL假设。In the prior art, the terminal assumes that the antenna ports corresponding to two SS/PBCH blocks with the same index number in any two synchronization signals (synchronization signal, SS) or physical broadcast channel (physical broadcast channel, PBCH) clusters periodically sent by the network device meet the QCL assumption, while the antenna ports corresponding to two SS/PBCH blocks with different index numbers in one SS/PBCH do not meet the QCL assumption. For the case where the antenna ports corresponding to two SS/PBCH blocks with different index numbers also meet the QCL assumption, the base station needs to indicate the terminal, but currently it can only indicate the case of uniform repetition, that is, in one SS/PBCH cluster, the number of SS/PBCH blocks in each group is the same, and the SS/PBCH blocks in the same group meet the QCL assumption.
采用现有的指示方式，由于只能指示均匀重复的情况，会对多波束传输及实现造成限制。The existing indication method can only indicate uniformly repeated situations, which will limit the multi-beam transmission and implementation.

本申请针对目前指示方式会限制多波束(beam)传输和实现的问题，提出一种新的信号传输方法。The present application proposes a new signal transmission method to address the problem that the current indication method may limit multi-beam transmission and implementation.
图2为本申请一实施例提供的信号传输方法流程示意图，如图2所示，该方法包括：FIG. 2 is a flow chart of a signal transmission method provided by an embodiment of the present application. As shown in FIG. 2 , the method includes:
S201、网络设备确定第一指示信息，该第一指示信息用于指示N个公共信号块采用第i种传输方式。S201. A network device determines first indication information, where the first indication information is used to indicate that N common signal blocks adopt an i-th transmission mode.
其中，第i种传输方式中，所述N个公共信号块包括Ri个公共信号块组，Ri个公共信号块组中有至少一组包括Pi个公共信号块、以及至少一组包括Ki个公共信号块，同一组的公共信号块满足准共址QCL假设，N和i为大于0的整数，Ri、Ki、Pi为大于0、小于或等于N的整数。Among them, in the i-th transmission mode, the N common signal blocks include Ri common signal block groups, among the Ri common signal block groups, at least one group includes Pi common signal blocks, and at least one group includes Ki common signal blocks, the common signal blocks in the same group satisfy the quasi-co-site QCL assumption, N and i are integers greater than 0, and Ri , Ki , and Pi are integers greater than 0 and less than or equal to N.
可选地，同一组的公共信号块的发射波束和/或接收波束方向相同。Optionally, the transmission beam and/or reception beam directions of the common signal blocks of the same group are the same.
可选地，这里的QCL假设可以包括空间相关性参数，多普勒参数，时延扩展参数，天线增益参数等中的至少一个。其中，空间相关性参数可以包括出发角度扩展，到达角度扩展，出发角，到达角等中的至少一个。Optionally, the QCL assumption here may include at least one of a spatial correlation parameter, a Doppler parameter, a delay spread parameter, an antenna gain parameter, etc. The spatial correlation parameter may include at least one of a departure angle spread, an arrival angle spread, a departure angle, an arrival angle, etc.
S202、网络设备向终端发送该第一指示信息。S202: The network device sends the first indication information to the terminal.
网络设备和终端可以预先约定好多种传输方式，由网络设备发送第一指示信息来指示当前需要使用的传输方式。可选地，可以在第一指示信息中携带第i种传输方式的标识，这个标识可以是第i种传输方式在所有传输方式中的编号、名称、一个或多个比特位表示的值等；也可以通过第一指示隐式指示第i种传输方式的标识，在此不作限制。The network device and the terminal may pre-agree on multiple transmission modes, and the network device sends the first indication information to indicate the transmission mode currently to be used. Optionally, the first indication information may carry an identifier of the i-th transmission mode, which may be the number, name, or value represented by one or more bits of the i-th transmission mode among all transmission modes; the identifier of the i-th transmission mode may also be implicitly indicated by the first indication, which is not limited here.
可选地，这里的传输方式可以为网络设备发送公共信号块的传输图样或QCL假设图样，如，公共信号块进行传输的重复图样等，或公共信号块传输时的QCL假设图样等。Optionally, the transmission mode here may be that the network device sends a transmission pattern or a QCL assumption pattern of a common signal block, such as a repeated pattern for transmitting a common signal block, or a QCL assumption pattern for transmitting a common signal block.
不同的传输方式中，N个公共信号块包括的公共信号块组数可能不一样，各组包括的公共信号块数量也能不同。In different transmission modes, the number of common signal block groups included in the N common signal blocks may be different, and the number of common signal blocks included in each group may also be different.
可选地，Ri个公共信号块组所包含的公共信号块个数可以不全相同。即可以区别于均匀重复的方式，更为灵活的给N个公共信号块分组。以奇数个公共信号块为例，假设有7个公共信号块，如果采用均匀重复的方式，只能包括1组或7组公共信号块，而如果采用本申请的指示方式，可以支持将N个公共信号块分成包括1、2、3、4、5、6、7等任意数量公共信号块的公共信号块组。Optionally, the number of common signal blocks included in the Ri common signal block groups may not be all the same. That is, it is possible to group the N common signal blocks more flexibly, different from the uniform repetition method. Taking an odd number of common signal blocks as an example, assuming that there are 7 common signal blocks, if the uniform repetition method is adopted, only 1 group or 7 groups of common signal blocks can be included, while if the indication method of the present application is adopted, it can support the division of the N common signal blocks into common signal block groups including 1, 2, 3, 4, 5, 6, 7, etc., any number of common signal blocks.
S203、终端根据该第一指示信息接收网络设备传输的信息。S203: The terminal receives information transmitted by the network device according to the first indication information.
终端收到第一指示信息后，就可以获知网络设备要采用哪种传输方式来传输信息，也就可以知道其中哪些公共信息块满足准共址假设。进而终端根据该第一指示信息接收网络设备传输的信息。After receiving the first indication information, the terminal can know which transmission mode the network device will use to transmit information, and also know which common information blocks meet the quasi-co-location assumption. Then, the terminal receives the information transmitted by the network device according to the first indication information.
本申请中，网络设备确定第一指示信息，该第一指示信息用于指示N个公共信号块采用第i种传输方式，第i种传输方式中，所述N个公共信号块包括Ri个公共信号块组，Ri个公共信号块组中有至少一组包括Pi个公共信号块、以及至少一组包括Ki个公共信号块，同一组的公共信号块满足准共址QCL假设，N和i为大于0的整数，Ri、Ki、Pi为大于0、小于或等于N的整数，进而网络设备向终端发送该第一指示信息，终端收到第一指示信息后，根据该第一指示信息接收网络设备传输的信息。实现了公共信号块的分组更为灵活，每组所包含的公共信息块个数也更为灵活，以更好地支持多波束传输与实现。In the present application, the network device determines the first indication information, which is used to indicate that N common signal blocks adopt the i-th transmission mode. In the i-th transmission mode, the N common signal blocks include Ri common signal block groups, and at least one group of the Ri common signal block groups includes Pi common signal blocks, and at least one group includes Ki common signal blocks. The common signal blocks of the same group meet the quasi-co-location QCL assumption, N and i are integers greater than 0, Ri , Ki , and Pi are integers greater than 0 and less than or equal to N, and then the network device sends the first indication information to the terminal. After receiving the first indication information, the terminal receives the information transmitted by the network device according to the first indication information. The grouping of common signal blocks is more flexible, and the number of common information blocks contained in each group is also more flexible, so as to better support multi-beam transmission and implementation.
一种实现方式中，第i种传输方式中的Ki不等于Pi。预先设定好的传输方式可以有多种，在多种传输方式中，有至少一种传输方式中存在两组公共信号块组中包含的公共信号块个数不同。当然，这里不排除，在多种传输方式中，有至少一种传输方式中存在两组公共信号块组中包含的公共信号块个数相同。同样不排除，Ri等于1的情况，即N个公共信号块间是满足QCL假设的。In one implementation,Ki in the i-th transmission mode is not equal toPi . There may be multiple pre-set transmission modes, and in at least one of the multiple transmission modes, there are two groups of common signal blocks with different numbers of common signal blocks. Of course, it is not excluded that in at least one of the multiple transmission modes, there are two groups of common signal blocks with the same number of common signal blocks. It is also not excluded thatRi is equal to 1, that is, the QCL assumption is satisfied between the N common signal blocks.
需要说明的是，当i的取值不同时，Ki的取值可以相同或不同。当i的取值不同时，Pi的取值可以相同或不同。且当i的取值不同时，Ri的取值可以相同或不同。It should be noted that when the value of i is different, the value of Ki can be the same or different. When the value of i is different, the value of Pi can be the same or different. And when the value of i is different, the value of Ri can be the same or different.
可选地，在上述实施例的基础上Ri等于Pi等于N％Ki。即上述N个公共信号块包括个公共信号块组，个公共信号块组中有至少一组包括N％Ki个公共信号块、以及至少一组包括Ki个公共信号块。其中，表示对“N/Ki”向上取整，“/”为除号，“％”为求模，N％Ki表示N/Ki的余数。按照这种方式对N个公共信号块进行合理的划分，且任意两组中公共信号块的数量可以相等、也可以不相等，不存在局限性。Optionally, based on the above embodiment, Ri is equal to Pi is equal to N%Ki . That is, the above N common signal blocks include Common signal block groups, Among the common signal block groups, at least one group includes N%Ki common signal blocks, and at least one group includes Ki common signal blocks. Indicates that "N/Ki " is rounded up, "/" is a division sign, "%" is a modulus, and N%Ki represents the remainder of N/Ki . In this way, the N common signal blocks are reasonably divided, and the number of common signal blocks in any two groups can be equal or unequal, without any limitation.
进一步地，Ri个公共信号块组中有至少一组包括Pi个公共信号块、以及至少一组包括Ki个公共信号块可以具体为：个公共信号块组中有一组包括N％Ki个公共信号块、其他组中每组包括Ki个公共信号块。Further, among the Ri common signal block groups, at least one group includes Pi common signal blocks, and at least one group includes Ki common signal blocks may be specifically: There is one group of common signal blocks including N%Ki common signal blocks, and the others Each of the groups includesKi common signal blocks.
更具体地，还可以预先确定好哪一组包括Ki个公共信号块，例如可以是组中的第一组或最后一组包括N％Ki个公共信号块，其他组都包括Ki个公共信号块，但也不以此为限，可以指定其中一组包括N％Ki个公共信号块。More specifically, it can also be predetermined which group includes Ki common signal blocks, for example The first or last group in the group includes N%Ki common signal blocks, and the other groups include Ki common signal blocks, but this is not limited to it, and one of the groups can be specified to include N%Ki common signal blocks.
终端收到第一指示信息后，就可以确定分为几组，各组包括几个公共信号块。一般地，会先确定Ki，根据Ki进一步推断其他参数。After receiving the first indication information, the terminal can determine how many groups to divide into, each group including how many common signal blocks. Generally, Ki is determined first, and other parameters are further inferred based on Ki .
可选地，预先规定的传输方式可以以表1的形式存储在网络设备和终端中，以共包括8种传输方式为例，如表1所示：Optionally, the predefined transmission mode may be stored in the network device and the terminal in the form of Table 1, taking a total of 8 transmission modes as an example, as shown in Table 1:
表1Table 1
可选地，预先规定的传输方式还可以以表2的形式存储在网络设备和终端中，以共包括8种传输方式为例，如表2所示：Optionally, the predefined transmission mode may also be stored in the network device and the terminal in the form of Table 2, taking a total of 8 transmission modes as an example, as shown in Table 2:
表2Table 2
表1、表2中以3个比特位作为传输方式标识为例，第一指示信息包括传输方式标识，但不以此为限。In Table 1 and Table 2, 3 bits are used as the transmission mode identifier as an example, and the first indication information includes the transmission mode identifier, but is not limited to this.
图3为本申请一实施例提供的信号传输方法中公共信号块传输方式示意图。图3每行公共信号块中同花色阴影的公共信号块表示同一组的公共信号块，同一组的公共信号块均满足QCL假设。如图3所示，以N＝8为例，有如下几种传输方式：FIG3 is a schematic diagram of a common signal block transmission method in a signal transmission method provided by an embodiment of the present application. Common signal blocks with the same color shade in each row of common signal blocks in FIG3 represent common signal blocks of the same group, and the common signal blocks of the same group all meet the QCL assumption. As shown in FIG3, taking N=8 as an example, there are the following transmission methods:
1)第一行示例中，一组包括8个公共信号块，即Ki＝8，N％Ki＝0，因此8个公共信号块就分为1组，这1组8个公共信号块均满足QCL假设。1) In the first row of examples, a group includes 8 common signal blocks, that is,Ki = 8, N%Ki = 0, Therefore, the 8 common signal blocks are divided into 1 group, and the 8 common signal blocks in this group all meet the QCL assumption.

7)第七行示例中，Ki＝2，N％Ki＝0，即8个公共信号块分为4组，这4组都包括2个公共信号块。7) In the seventh row example,Ki = 2, N%Ki = 0, That is, the 8 common signal blocks are divided into 4 groups, and the 4 groups each include 2 common signal blocks.

另外，公共信号块的个数可以为偶数也可以为奇数。以N＝7为例，有如下几种传输方式：In addition, the number of common signal blocks can be an even number or an odd number. Taking N=7 as an example, there are several transmission modes as follows:
1)Ki＝7，N％Ki＝0，因此7个公共信号块就分为1组，这1组7个公共信号块均满足QCL假设。1)Ki = 7, N%Ki = 0, Therefore, the 7 common signal blocks are divided into 1 group, and the 7 common signal blocks in this group all meet the QCL assumption.

可选地，也可以有其他的分组方式，例如个公共信号块组中有一组包括Ki个公共信号块、其他组中每组包括N％Ki个公共信号块等，本申请不做限制。Alternatively, there may be other grouping methods, such as There is one group of common signal blocks including Ki common signal blocks, and the other Each group in the group includes N%Ki common signal blocks, etc., which is not limited in this application.
或者，可以直接规定每组包括几个公共信号块。可以适用于公共信号块较少的情况，但在此不作限制。Alternatively, it may be directly specified that each group includes several common signal blocks, which may be applicable to a situation where there are fewer common signal blocks, but is not limited here.

1)第一行示例中，一组包括4个公共信号块，Ki＝4，N％Ki＝0，因此4个公共信号块就分为1组。1) In the first row example, a group includes 4 common signal blocks,Ki = 4, N%Ki = 0, Therefore, the four common signal blocks are divided into one group.
2)第二行示例中，Ki＝3，N％Ki＝1，即4个公共信号块分为2组，一组包括3个公共信号块，另一组包括1个公共信号块。2) In the second row example,Ki = 3, N%Ki = 1, That is, the four common signal blocks are divided into two groups, one group includes three common signal blocks, and the other group includes one common signal block.
3)第三行示例中，Ki＝2，满足降序，4个公共信号块分为3组，第一组包括2个公共信号块，另两组包括1个公共信号块。3) In the third row example,Ki = 2, which satisfies the descending order. The four common signal blocks are divided into three groups. The first group includes two common signal blocks, and the other two groups include one common signal block.
4)第四行示例中，Ki＝2，N％Ki＝2，即4个公共信号块分为2组，一组包括2个公共信号块，另一组也包括2个公共信号块。4) In the fourth row example,Ki = 2, N%Ki = 2, That is, the four common signal blocks are divided into two groups, one group includes two common signal blocks, and the other group also includes two common signal blocks.
5)第五行示例中，Ki＝4，N％Ki＝0，即4个公共信号块分为4组，这4组都包括1个公共信号块。5) In the fifth row example,Ki = 4, N%Ki = 0, That is, the four common signal blocks are divided into four groups, and each of the four groups includes one common signal block.
当载频频段较高(大于预设阈值)时，N的可能取值也较大，为减少指示开销，一种可选的方法可以是，采用两级或多级指示的方式，即，在不同的载频频段假设下将N个公共信号块分为Y组，每组各包括X个公共信号块，N＝X*Y。其中，X、Y为大于或等于1的整数。When the carrier frequency band is high (greater than a preset threshold), the possible value of N is also large. To reduce the indication overhead, an optional method may be to use a two-level or multi-level indication method, that is, to divide the N common signal blocks into Y groups under different carrier frequency band assumptions, each group includes X common signal blocks, N = X * Y. Wherein, X and Y are integers greater than or equal to 1.
此时，第一指示信息由Y组的组指示信息域和每组内X个公共信号块的指示信息域组成，其中，位于Y组中不同组内的第j个公共信号块间是满足QCL假设的，而每组内的X个公共信号块间的QCL假设信息根据上述第一指示信息中每组内X个公共信号块的指示信息域字段来获得。其中，每组内的X个公共信号块间的QCL假设信息的指示方法可以为本申请方案中的任意一种。j为大于0且小于或等于X的整数。At this time, the first indication information is composed of a group indication information field of Y groups and an indication information field of X common signal blocks in each group, wherein the j-th common signal blocks in different groups in the Y group satisfy the QCL assumption, and the QCL assumption information between the X common signal blocks in each group is obtained according to the indication information field of the X common signal blocks in each group in the first indication information. The indication method of the QCL assumption information between the X common signal blocks in each group can be any one of the schemes of the present application. j is an integer greater than 0 and less than or equal to X.
进一步地，在上述实施例的基础上，网络设备还可以确定第二指示信息，并向终端发送该第二指示信息。其中，网络设备向终端发送第二指示信息，可以是：网络设备可以通过系统信息中的域字段向终端发送第二指示信息，或者通过RRC向终端发送第二指示信息。Further, based on the above embodiment, the network device may also determine second indication information and send the second indication information to the terminal. The network device sending the second indication information to the terminal may be: the network device may send the second indication information to the terminal through a domain field in the system information, or send the second indication information to the terminal through RRC.
该第二指示信息用于指示M个公共信号块中的N个公共信号块。其中，M为大于或等于N的整数。The second indication information is used to indicate N common signal blocks among the M common signal blocks, where M is an integer greater than or equal to N.
可选地，上述公共信号块的最大个数可以根据载频频段的不同而不同。如，当载频频段小于或等于3千兆赫兹(GHz)时，公共信号块的最大个数为4，当载频频段大于3GHz、小于或等于6GHz时，公共信号块的最大个数为8，而当载频频段大于6GHz时，N个公共信号块的最大个数为64。上述N为大于0、且小于或等于上述公共信号块的最大个数的整数。Optionally, the maximum number of the common signal blocks may vary according to the carrier frequency band. For example, when the carrier frequency band is less than or equal to 3 gigahertz (GHz), the maximum number of common signal blocks is 4, when the carrier frequency band is greater than 3 GHz and less than or equal to 6 GHz, the maximum number of common signal blocks is 8, and when the carrier frequency band is greater than 6 GHz, the maximum number of N common signal blocks is 64. The above N is an integer greater than 0 and less than or equal to the above maximum number of common signal blocks.
相应地，M可以是网络设备可能发送的公共信号块的总个数，M根据载频频段的不同而不同，如，当载频频段小于或等于3GHz时，M为4，当载频频段大于3GHz、小于或等于6GHz时，M为8，而当载频频段大于6GHz时，M为64。Correspondingly, M can be the total number of common signal blocks that the network device may send, and M varies according to the carrier frequency band. For example, when the carrier frequency band is less than or equal to 3 GHz, M is 4; when the carrier frequency band is greater than 3 GHz and less than or equal to 6 GHz, M is 8; and when the carrier frequency band is greater than 6 GHz, M is 64.
但实际传输过程中，可能只发送其中部分公共信号块。通过第二指示信息，网络设备可以标识出M个公共信号块中的实际传输的N个公共信号块。However, in the actual transmission process, only some of the common signal blocks may be sent. Through the second indication information, the network device can identify the N common signal blocks that are actually transmitted among the M common signal blocks.
可选地，第二指示信息用于指示实际传输信号时使用的公共信号块。上述N个公共信号块是网络设备实际传输信号时使用的公共信号块。或上述N个公共信号块也可以是网络设备可能发送的公共信号块的总个数。Optionally, the second indication information is used to indicate the common signal blocks used when actually transmitting the signal. The above-mentioned N common signal blocks are the common signal blocks used when the network device actually transmits the signal. Or the above-mentioned N common signal blocks may also be the total number of common signal blocks that the network device may send.
一种实施方式中，网络设备根据第二指示信息确定第一指示信息的比特数。这种实施方式中，先确定第二指示信息，进而第一指示信息依赖于第二指示信息。第二指示信息中可以由多个比特位来指示，每个比特位对应一个公共信号块，以指示M个可能的公共信号块中的每一个公共信号块是否是实际传输所用的公共信号块。In one implementation, the network device determines the number of bits of the first indication information according to the second indication information. In this implementation, the second indication information is first determined, and then the first indication information depends on the second indication information. The second indication information may be indicated by a plurality of bits, each bit corresponding to a common signal block, to indicate whether each of the M possible common signal blocks is a common signal block used for actual transmission.
具体地，第一指示信息的比特数可以随着第二指示信息所指示的公共信号块个数N的大小而调整，例如当第二指示信息指示的公共信号块个数N较大时，第一指示信息需要较多的比特位指示，第一指示信息的比特数也将较大，而如果当第二指示信息指示的公共信号块个数N较小时，则第一指示信息的比特数也相应减少。Specifically, the number of bits of the first indication information can be adjusted according to the size of the number N of common signal blocks indicated by the second indication information. For example, when the number N of common signal blocks indicated by the second indication information is larger, the first indication information requires more bits to indicate, and the number of bits of the first indication information will also be larger. If the number N of common signal blocks indicated by the second indication information is smaller, the number of bits of the first indication information will also be reduced accordingly.
举例说明，对于8个公共信号块有8种传输方式，4个公共信号块有5种传输方式，需要3个比特位指示。如果只有3个公共信号块时，可以只需要2个比特位指示，无需浪费更多的比特位。For example, there are 8 transmission modes for 8 common signal blocks and 5 transmission modes for 4 common signal blocks, which require 3 bits to indicate. If there are only 3 common signal blocks, only 2 bits are required to indicate, without wasting more bits.
本实施方式中，网络设备先向终端发送第二指示信息，终端收到第二指示信息后，根据第二指示信息所指示的N个公共信号块，也可以确定出后续第一指示信息中有几个比特位来指示传输方式。In this implementation, the network device first sends the second indication information to the terminal. After receiving the second indication information, the terminal can also determine how many bits in the subsequent first indication information are used to indicate the transmission mode based on the N common signal blocks indicated by the second indication information.
另一种实施方式中，网络设备根据第一指示信息确定第二指示信息的比特数。In another implementation, the network device determines the number of bits of the second indication information according to the first indication information.
这种实施方式中，网络设备可以在第一指示信息的基础上再指示公共信号块，以节省第二指示信息的比特位。In this implementation manner, the network device may indicate the common signal block based on the first indication information to save bits of the second indication information.
可选地，网络设备先确定第一指示信息要指示的第i种传输方式，然后根据第i种传输方式确定第二指示信息。由于网络设备先发送了第一指示信息，终端已经根据第一指示信息获知了N个公共信号块包括Ri个公共信号块组，Ri个公共信号块组中有至少一组包括Pi个公共信号块、以及至少一组包括Ki个公共信号块这些信息。那么第二指示信息中可以每个比特位指示一个公共信号块组，相比于每个比特位指示一个公共信号块要节约比特位。Optionally, the network device first determines the i-th transmission mode to be indicated by the first indication information, and then determines the second indication information according to the i-th transmission mode. Since the network device first sends the first indication information, the terminal has learned from the first indication information that the N common signal blocks include Ri common signal block groups, at least one group of the Ri common signal block groups includes Pi common signal blocks, and at least one group includes Ki common signal blocks. Then, each bit in the second indication information can indicate a common signal block group, which saves bits compared to indicating one common signal block per bit.
在上述实施例的基础上，上述公共信号块可以包括：SS、PBCH中至少一个。可以记为SS/PBCH block。Based on the above embodiment, the above common signal block may include: at least one of SS and PBCH, which may be recorded as SS/PBCH block.
在长期演进(long term evolution，LTE)网络中，终端通过检测每一个小区的主同步信号(Primary Synchronization，PSS)和辅同步信号(Secondary Synchronization，SSS)，与小区在时间和频率上获得同步。终端在检测到同步信号后的初始接入过程中，终端进一步解码物理广播信道(Physical Broadcasting Channel，PBCH)获得关键系统信息，该关键信息主要包括主信息块(Master Information Blocks，MIB)和系统信息块(SystemInformation Blocks，SIB)。在LTE中，PBCH在每个子帧内，时域上占用4个符号，频域上占用6个资源块(Resource Block，RB)，在前两个符号上，PBCH的传输带宽内共有8个资源元素(Resource Element，RE)上映射参考信号，其中，该参考信号一般为小区特定导频信号(Cell-specific reference signals，CRS)，终端利用CRS对PBCH进行信道估计，并根据此信道估计结果完成对PBCH的解码。这里的符号指的是OFDM符号，是PBCH映射和传输的一个时间粒度。In the long term evolution (LTE) network, the terminal obtains synchronization with the cell in time and frequency by detecting the primary synchronization signal (PSS) and secondary synchronization signal (SSS) of each cell. During the initial access process after the terminal detects the synchronization signal, the terminal further decodes the physical broadcast channel (PBCH) to obtain key system information, which mainly includes the master information block (MIB) and the system information block (SIB). In LTE, PBCH occupies 4 symbols in the time domain and 6 resource blocks (RB) in the frequency domain in each subframe. In the first two symbols, a reference signal is mapped on a total of 8 resource elements (RE) within the transmission bandwidth of PBCH. Among them, the reference signal is generally a cell-specific reference signal (CRS). The terminal uses CRS to perform channel estimation on PBCH and completes the decoding of PBCH based on this channel estimation result. The symbol here refers to the OFDM symbol, which is a time granularity for PBCH mapping and transmission.
在5G NR中，则重新定义了PBCH的结构以及所采用的参考信号。在5G NR中，PBCH在时域上占用两个符号，在频域上PBCH的传输带宽由288个资源元素组成。对应24个RB，并且PBCH的两个符号上，在PBCH的传输带宽内均映射有参考信号。在5G NR中广播信道的数据解调或信道估计所采用的参考信号为解调参考信号(Demodulation Reference Signal，DMRS)。在5G NR中还定义了同步信号/物理广播信道块(Synchronous Signal/PhysicalBroadcast Channel block，SS/PBCH block)的概念，对于包括5G NR中的PSS，SSS和PBCH的一个SS/PBCH block，PBCH占用频域上的288个资源元素，或占用24个RB，PSS和SSS则分别占用与广播信道传输相邻的两个符号上，广播信道带宽内的中间127个资源元素，或中间的12个RB，即PSS占用与广播信道相邻的一个符号上广播信道带宽内的中间127个资源元素，而SSS占用与广播信道相邻的另一个符号上广播信道带宽内的中间127个资源元素。In 5G NR, the structure of PBCH and the reference signals used are redefined. In 5G NR, PBCH occupies two symbols in the time domain, and the transmission bandwidth of PBCH in the frequency domain consists of 288 resource elements. Corresponding to 24 RBs, and reference signals are mapped on both symbols of PBCH within the transmission bandwidth of PBCH. The reference signal used for data demodulation or channel estimation of the broadcast channel in 5G NR is the demodulation reference signal (DMRS). The concept of Synchronous Signal/Physical Broadcast Channel block (SS/PBCH block) is also defined in 5G NR. For an SS/PBCH block including PSS, SSS and PBCH in 5G NR, PBCH occupies 288 resource elements in the frequency domain, or 24 RBs, and PSS and SSS occupy the middle 127 resource elements or the middle 12 RBs in the broadcast channel bandwidth of two symbols adjacent to the broadcast channel transmission, that is, PSS occupies the middle 127 resource elements in the broadcast channel bandwidth of a symbol adjacent to the broadcast channel, and SSS occupies the middle 127 resource elements in the broadcast channel bandwidth of another symbol adjacent to the broadcast channel.
进一步地，网络设备向终端发送第一指示信息，也可以有多种不同的方式：Furthermore, the network device may send the first indication information to the terminal in a variety of different ways:
可选地，网络设备通过系统信息向终端发送第一指示信息。即第一指示信息携带在系统信息中。Optionally, the network device sends the first indication information to the terminal via system information, that is, the first indication information is carried in the system information.
或者，网络设备通过PBCH消息向所述终端发送所述第一指示信息。即第一指示信息携带在PBCH消息中。Alternatively, the network device sends the first indication information to the terminal via a PBCH message, that is, the first indication information is carried in the PBCH message.
或者，网络设备通过高层无线资源控制信令(radio resource control，RRC)向所述终端发送所述第一指示信息。即第一指示信息携带在RRC中。Alternatively, the network device sends the first indication information to the terminal via a high-level radio resource control signaling (radio resource control, RRC), that is, the first indication information is carried in the RRC.
第一指示信息在这些信息中占一个或多个比特位。The first indication information occupies one or more bits in the information.
可选地，网络设备还可以通过PBCH的公共信号块时序索引字段向终端发送第一指示信息。Optionally, the network device may also send the first indication information to the terminal via the common signal block timing index field of the PBCH.
需要说明的是，PBCH的负载(payload)中存在一个3比特的公共信号块时序索引字段(例如SS block time index)。这3比特的公共信号块时序索引字段在低频场景下是空闲的，而公共信号块满足准共址假设(等价于SS/PBCH block重复传输的机制)更适用于低频场景。因此第一指示信息可以利用PBCH中此3比特的公共信号块时序索引字段来携带，这样可以更好地节省信令开销。It should be noted that there is a 3-bit common signal block timing index field (such as SS block time index) in the PBCH payload. This 3-bit common signal block timing index field is idle in low-frequency scenarios, and the common signal block satisfies the quasi-co-location assumption (equivalent to the mechanism of repeated transmission of SS/PBCH block) and is more suitable for low-frequency scenarios. Therefore, the first indication information can be carried using this 3-bit common signal block timing index field in PBCH, which can better save signaling overhead.
可选地，在第一载频频段时，网络设备向终端发送第一指示信息可以是：网络设备通过系统信息中携带第二指示信息的域字段向终端发送第一指示信息。Optionally, in the first carrier frequency band, the network device sending the first indication information to the terminal may be: the network device sends the first indication information to the terminal via a domain field carrying the second indication information in the system information.
第一载频频段大于预设阈值。该预设阈值可以为6GHz，但不以此为限。The first carrier frequency band is greater than a preset threshold, which may be 6 GHz, but is not limited thereto.
这种实施方式中，网络设备通过携带第二指示信息的域字段隐式指示了第一指示信息。In this implementation manner, the network device implicitly indicates the first indication information by carrying the domain field of the second indication information.
具体地，一种方式中：第二指示信息可以由公共信号块组的指示比特位图和每个公共信号块组内的公共信号块指示比特位图组成。其中，M个公共信号块分为A组，每组包括B个公共信号块，M＝A*B，A、B为大于或等于1的整数。公共信号块组的指示比特位图用于指示A个公共信号块组中哪些为实际传输的公共信号块组，而每个公共信号块组内的公共信号块的指示比特位图用于指示B个公共信号块中哪些为实际传输的公共信号块。在上述第二指示信息的指示方法中，公共信号块组的指示比特位图指示的A个公共信号块组中不同组内的第j个公共信号块间默认是满足QCL假设的，而每个公共信号块组内的公共信号块的指示比特位图指示的每组内的B个公共信号块间默认是不满足QCL假设的。或公共信号块组的指示比特位图指示的A个公共信号块组中不同组内的第j个公共信号块间默认是不满足QCL假设的，而每个公共信号块组内的公共信号块的指示比特位图指示的每个公共信号块组内的B个公共信号块间默认是满足QCL假设的。这里，j为小于或等于B的正整数。Specifically, in one method: the second indication information may be composed of an indication bit map of a common signal block group and an indication bit map of a common signal block in each common signal block group. Among them, M common signal blocks are divided into A groups, each group includes B common signal blocks, M=A*B, A and B are integers greater than or equal to 1. The indication bit map of the common signal block group is used to indicate which of the A common signal block groups are common signal block groups actually transmitted, and the indication bit map of the common signal blocks in each common signal block group is used to indicate which of the B common signal blocks are common signal blocks actually transmitted. In the indication method of the second indication information mentioned above, the j-th common signal blocks in different groups of the A common signal block groups indicated by the indication bit map of the common signal block group meet the QCL assumption by default, while the B common signal blocks in each group indicated by the indication bit map of the common signal blocks in each common signal block group do not meet the QCL assumption by default. Or the j-th common signal blocks in different groups of A common signal block groups indicated by the indication bitmap of the common signal block group do not meet the QCL assumption by default, while the B common signal blocks in each common signal block group indicated by the indication bitmap of the common signal blocks in each common signal block group meet the QCL assumption by default. Here, j is a positive integer less than or equal to B.
另一种方式中：第二指示信息由公共信号块组的指示比特位图和每个公共信号块组内的公共信号块的指示比特图组成，其中，M个公共信号块分为A组，每组包括B个公共信号块，M＝A*B，A、B为大于或等于1的整数。公共信号块组的指示比特位图用于指示A个公共信号块组中哪些为实际传输的公共信号块组，而每组内的公共信号块的指示比特用于指示B个公共信号块中实际传输的公共信号块的个数Q。在第二指示信息的指示方法中，公共信号块组的指示比特位图指示的A个公共信号块组中不同组内的第j个公共信号块间默认是满足QCL假设的，而每个公共信号块组内的公共信号块的指示比特指示的每个公共信号块组内的B个公共信号块间默认是不满足QCL假设的。或公共信号块组的指示比特位图指示的A个公共信号块组中不同组内的第j个公共信号块间默认是不满足QCL假设的，而每个公共信号块组内的公共信号块的指示比特指示的每组内的Q个公共信号块间默认是满足QCL假设的。这里，j，Q为小于或等于B的正整数。In another way: the second indication information is composed of an indication bitmap of a common signal block group and an indication bitmap of a common signal block in each common signal block group, wherein M common signal blocks are divided into A groups, each group includes B common signal blocks, M=A*B, and A and B are integers greater than or equal to 1. The indication bitmap of the common signal block group is used to indicate which common signal block groups are actually transmitted among the A common signal block groups, and the indication bits of the common signal blocks in each group are used to indicate the number Q of common signal blocks actually transmitted among the B common signal blocks. In the indication method of the second indication information, the j-th common signal blocks in different groups of the A common signal block groups indicated by the indication bitmap of the common signal block group meet the QCL assumption by default, while the B common signal blocks in each common signal block group indicated by the indication bits of the common signal blocks in each common signal block group do not meet the QCL assumption by default. Or the j-th common signal blocks in different groups of A common signal block groups indicated by the indication bit map of the common signal block group do not meet the QCL assumption by default, while the Q common signal blocks in each group indicated by the indication bit of the common signal block in each common signal block group meet the QCL assumption by default. Here, j, Q are positive integers less than or equal to B.
可选地，第二指示信息可以由网络设备通过终端特定的RRC信令通知给终端。此终端特定的RRC信令可以为比特位图的形式，比特图中以1标识实际传输的公共信号块，0标识未传输的公共信号块。如：1010000，表示的意思为8个公共信号块中第一个公共信号块和第三个公共信号块为实际传输的公共信号块，而其他公共信号块为未传输的公共信号块。该第二指示信息的通知方法适用于所有载频频段，包括6GHz以下的载频频段和6GHz以上的载频频段。Optionally, the second indication information can be notified to the terminal by the network device through terminal-specific RRC signaling. This terminal-specific RRC signaling can be in the form of a bit map, in which 1 identifies the common signal block that is actually transmitted, and 0 identifies the common signal block that is not transmitted. For example: 1010000, which means that the first common signal block and the third common signal block among the 8 common signal blocks are the common signal blocks that are actually transmitted, and the other common signal blocks are the common signal blocks that are not transmitted. The notification method of the second indication information is applicable to all carrier frequency bands, including carrier frequency bands below 6 GHz and carrier frequency bands above 6 GHz.
另一种实施方式中，当载频频段较高时，如在载频频段大于6GHz时，网络设备通过系统信息向终端发送第二指示信息。具体可以将第二指示信息携带在系统信息的域字段。In another implementation, when the carrier frequency band is high, such as when the carrier frequency band is greater than 6 GHz, the network device sends the second indication information to the terminal via system information. Specifically, the second indication information can be carried in a domain field of the system information.
这里的系统信息可以为，剩余最小系统信息(Remaining Minimum SystemInformation，RMSI)，其他系统信息(Other System Information，OSI)，或其他类型的系统信息中的任意一种，这里不做具体限定。The system information here may be any one of remaining minimum system information (Remaining Minimum System Information, RMSI), other system information (Other System Information, OSI), or other types of system information, which is not specifically limited here.
更进一步地，当载频频段较高时，网络设备既可以通过终端特定的RRC信令采用比特位图的形式通知给终端，也可以由网络设备通过系统信息通知给终端设备，对于RRC连接态的终端来说，由于RRC信令的方式更精准和容易获取，因此，网络设备可只基于终端特定的RRC信令来携带和传输第二指示信息，而系统信息中预留携带的第二指示信息的域字段可用来携带第一指示信息。此实施方式，也可减少和最小化网络设备指示的信令比特数。Furthermore, when the carrier frequency band is high, the network device can notify the terminal in the form of a bitmap through terminal-specific RRC signaling, or the network device can notify the terminal device through system information. For terminals in RRC connection state, since the RRC signaling method is more accurate and easy to obtain, the network device can only carry and transmit the second indication information based on the terminal-specific RRC signaling, and the domain field reserved for carrying the second indication information in the system information can be used to carry the first indication information. This implementation method can also reduce and minimize the number of signaling bits indicated by the network device.
本申请还提供一种信号传输方法，该方法中，网络设备确定第三指示信息，通过物理广播信道的公共信号块时序索引字段向终端发送所述第三指示信息。终端收到第三指示信息后，根据第三指示信息接收网络设备发送的信息。The present application also provides a signal transmission method, in which a network device determines third indication information and sends the third indication information to a terminal through a common signal block timing index field of a physical broadcast channel. After receiving the third indication information, the terminal receives information sent by the network device according to the third indication information.
其中，该第三指示信息用于指示N个公共信号块采用第i种传输方式，其中，所述第i种传输方式中，所述N个公共信号块包括Ri个公共信号块组，同一组的公共信号块满足准共址QCL假设，N和i为大于0的整数，Ri为大于0、小于或等于N的整数。Among them, the third indication information is used to indicate that N common signal blocks adopt the i-th transmission mode, wherein in the i-th transmission mode, the N common signal blocks include Ri common signal block groups, and the common signal blocks in the same group satisfy the quasi-co-site QCL assumption, N and i are integers greater than 0, and Ri is an integer greater than 0 and less than or equal to N.
需要说明的是，PBCH的负载(payload)中存在一个3比特的公共信号块时序索引字段(例如SS block time index)。这3比特的公共信号块时序索引字段在低频场景下是空闲的，而公共信号块满足准共址假设(等价于SS/PBCH block重复传输的机制)更适用于低频场景。因此第一指示信息可以利用PBCH中此3比特的公共信号块时序索引字段来携带，这样可以更好地节省信令开销。It should be noted that there is a 3-bit common signal block timing index field (such as SS block time index) in the PBCH payload. This 3-bit common signal block timing index field is idle in low-frequency scenarios, and the common signal block satisfies the quasi-co-location assumption (equivalent to the mechanism of repeated transmission of SS/PBCH block) and is more suitable for low-frequency scenarios. Therefore, the first indication information can be carried using this 3-bit common signal block timing index field in PBCH, which can better save signaling overhead.
本申请还提供一种信号传输方法，该方法中，网络设备确定第四指示信息，在第一载频频段时通过系统信息中的域字段向终端发送所述第四指示信息。终端收到第四指示信息后，根据第四指示信息接收网络设备发送的信息。The present application also provides a signal transmission method, in which the network device determines fourth indication information, and sends the fourth indication information to the terminal through a domain field in the system information in the first carrier frequency band. After receiving the fourth indication information, the terminal receives information sent by the network device according to the fourth indication information.
第四指示信息用于指示N个公共信号块采用第i种传输方式，其中，所述第i种传输方式中，所述N个公共信号块包括Ri个公共信号块组，同一组的公共信号块满足准共址QCL假设，N和i为大于0的整数，Ri为大于0、小于或等于N的整数。The fourth indication information is used to indicate that N common signal blocks adopt the i-th transmission mode, wherein in the i-th transmission mode, the N common signal blocks include Ri common signal block groups, the common signal blocks in the same group satisfy the quasi-co-site QCL assumption, N and i are integers greater than 0, and Ri is an integer greater than 0 and less than or equal to N.
本实施例中，网络设备通过携带第二指示信息的域字段隐式指示了第四指示信息。当载频频段较高时，如在载频频段大于6GHz时，网络设备通过系统信息的域字段向终端发送上述第二指示信息并隐式指示第四指示信息。具体可以参见前述实施例网络设备通过携带第二指示信息的域字段隐式指示第一指示信息的内容，在此不再赘述。In this embodiment, the network device implicitly indicates the fourth indication information by carrying the domain field of the second indication information. When the carrier frequency band is high, such as when the carrier frequency band is greater than 6GHz, the network device sends the second indication information to the terminal through the domain field of the system information and implicitly indicates the fourth indication information. For details, please refer to the aforementioned embodiment in which the network device implicitly indicates the content of the first indication information by carrying the domain field of the second indication information, which will not be repeated here.
本实施例也可减少和最小化网络设备指示的信令比特数。This embodiment can also reduce and minimize the number of signaling bits indicated by the network device.
上述实施例中，上述公共信号块可以包括：SS、PBCH中至少一个。可以记为SS/PBCHblock。In the above embodiment, the above common signal block may include: at least one of SS and PBCH, which may be recorded as SS/PBCHblock.
