如图1所示，本发明实施例提供一种取消上行传输的方法100，该方法可以由终端设备执行，包括如下步骤：As shown in FIG. 1, an embodiment of the present invention provides a method 100 for canceling uplink transmission, which can be executed by a terminal device, and includes the following steps:
S110：接收上行传输取消指令。S110: Receive an uplink transmission cancel instruction.
如前所述，该实施例可以应用在eMBB业务和URLLC业务共享同一个资源池的场景下，如果网络设备将URLLC传输调度到已分配给eMBB传输的频域资源，网络设备可以在eMBB业务的终端设备传输之前，向eMBB业务的终端设备发送上行传输取消指令(UpLinkCancellation Indication，UL CI)，若终端设备接收到来自网络设备的上述UL CI，即可执行S120。As mentioned above, this embodiment can be applied in the scenario where the eMBB service and the URLLC service share the same resource pool. If the network device schedules the URLLC transmission to the frequency domain resource allocated to the eMBB transmission, the network device can Before transmission, the terminal device sends an uplink cancellation instruction (UpLinkCancellation Indication, UL CI) to the terminal device of the eMBB service, and if the terminal device receives the above UL CI from the network device, it can execute S120.
S120：若所述上行传输取消指令中包括频域指示信息，根据所述频域指示信息，确定取消上行传输的目标频域资源。S120: If the uplink transmission cancellation instruction includes frequency domain indication information, determine a target frequency domain resource for canceling uplink transmission according to the frequency domain indication information.
上述UL CI中可以包括有频域指示信息，当然也可以不包括(频域指示信息)，终端设备在接收UL CI之前，通常是可以确定(如高层信令配置或协议规定的)UL CI中是否包括有频域指示信息。The above UL CI may include frequency domain indication information, of course, may not include (frequency domain indication information). Before receiving the UL CI, the terminal device can usually determine (as specified in the high-level signaling configuration or protocol) the UL CI Whether to include frequency domain indication information.
上述频域指示信息，可以是用来指示待暂停或待取消上行传输的目标频域资源。该处提到的目标频域资源，可以为一确定的参考频域区域(Reference Frequencyregion)；也可以是上述参考频域区域中的一个或多个频带子集。The above frequency domain indication information may be used to indicate target frequency domain resources to be suspended or to be canceled for uplink transmission. The target frequency domain resource mentioned here may be a determined reference frequency domain region (Reference Frequency region); it may also be one or more frequency band subsets in the above reference frequency domain region.
上述参考频域区域，可以是根据来自于网络设备的高层信令确定得到；或者是在协议中约定。在一种具体的实施方式中，所述参考频域区域默认为终端设备当前激活的上行带宽部分(BandWidth Part，BWP)；在另一种具体的实施方式中，所述参考频域区域为所述网络设备通过高层信令配置的频域带宽，该处配置的频域带宽，可以是上述当前激活的上行BWP，也可以是当前激活的上行BWP中的部分带宽。The above-mentioned reference frequency domain area may be determined according to high-level signaling from the network device; or it may be stipulated in a protocol. In a specific implementation manner, the reference frequency domain area defaults to the uplink bandwidth part (BandWidth Part, BWP) currently activated by the terminal device; in another specific implementation manner, the reference frequency domain area is the The frequency domain bandwidth configured by the network device through high-level signaling, the frequency domain bandwidth configured here may be the above-mentioned currently activated uplink BWP, or part of the bandwidth in the currently activated uplink BWP.
通过本发明实施例提供的取消上行传输的方法，终端设备在接收到上行传输取消指令时，若所述上行传输取消指令中包括频域指示信息，终端设备根据所述频域指示信息即可确定取消上行传输的目标频域资源，提高了系统的资源调度效率。Through the method for canceling uplink transmission provided by the embodiment of the present invention, when a terminal device receives an uplink transmission cancel instruction, if the uplink transmission cancel instruction includes frequency domain indication information, the terminal device can determine the frequency domain indication information according to the frequency domain indication information The resource scheduling efficiency of the system is improved by canceling the target frequency domain resources of the uplink transmission.
当然，在确定出目标频域资源之后，终端设备还可以暂停或取消在所述目标频域资源上的上行传输，从而实现了URLLC业务的低时延和高可靠性要求。Certainly, after the target frequency domain resource is determined, the terminal device may also suspend or cancel the uplink transmission on the target frequency domain resource, thereby realizing the low delay and high reliability requirements of the URLLC service.
上述提到，UL CI中的频域指示信息可以用来指示参考频域区域的一个或多个频带子集，即目标频域资源，其中，这些频带子集可以是对参考频域区域进行分段得到，例如，参考频域区域的带宽为400MHz-500MHz，被分为10个相等的频带子集，第一个频带子集为400MHz-410MHz；第二个频带子集为410MHz-420MHz；……；第十个频带子集为490MHz-500MHz。As mentioned above, the frequency domain indication information in the UL CI can be used to indicate one or more frequency band subsets of the reference frequency domain area, that is, target frequency domain resources, where these frequency band subsets can be used to divide the reference frequency domain area The section obtains, for example, the bandwidth of the reference frequency domain area is 400MHz-500MHz, which is divided into 10 equal frequency band subsets, the first frequency band subset is 400MHz-410MHz; the second frequency band subset is 410MHz-420MHz;… ...; the tenth frequency band subset is 490MHz-500MHz.
每个频带子集的大小、或者是频带子集的数量，均可以是根据自于网络设备的高层信令确定。每个频带子集的大小、或者是频带子集的数量，反映了频域资源指示的粒度。The size of each frequency band subset, or the number of frequency band subsets, may be determined according to high-layer signaling from the network device. The size of each frequency band subset, or the number of frequency band subsets, reflects the granularity of frequency domain resource indication.
对于UL CI中的频域指示信息指示一个或多个频带子集的方式，可以有如下几种实施方式：For the manner in which the frequency domain indication information in the UL CI indicates one or more frequency band subsets, there are several implementation manners as follows:
实施方式一，采用位图指示的方式指示频带子集。Embodiment 1: A bitmap indication is used to indicate the frequency band subset.
例如，参考频域区域被分割为M(M为大于1的正整数)个频带子集，这样，UL CI中的指示信息可以具体为M比特的位图，根据上述位图来指示出一个或多个频带子集，即目标频域资源。当M＝1时，UL CI中可以不包括频域指示信息(后续介绍)。For example, the reference frequency domain area is divided into M (M is a positive integer greater than 1) frequency band subsets. In this way, the indication information in the UL CI can be specifically an M-bit bitmap, and one or Multiple frequency band subsets, that is, target frequency domain resources. When M=1, the UL CI may not include frequency domain indication information (described later).
该处的M比特的位图可以用来指示参考频域区域的单个频带子集；或，可以用来指示参考频域区域的多个连续的频带子集；或，可以用来指示参考频域区域的多个不连续的频带子集。The M-bit bitmap here can be used to indicate a single frequency band subset of the reference frequency domain region; or, can be used to indicate multiple contiguous frequency band subsets of the reference frequency domain region; or, can be used to indicate the reference frequency domain Multiple discrete subsets of frequency bands for a region.
利用位图指示目标频域资源的方式，配置方便，指示方式灵活，可以按照灵活地指示一个或多个频带子集。The method of indicating the target frequency domain resource by using the bitmap is convenient for configuration and flexible for indicating, and can flexibly indicate one or more frequency band subsets.
实施方式二，采用单个索引指示的方式指示频带子集，例如，参考频域区域被分割为M(M为大于1的正整数)个频带子集，每一个频带子集均配置有索引，这样，UL CI中的指示信息可以具体用于指示频带子集的索引。当M＝1时，UL CI中可以不包括频域指示信息(后续介绍)。Embodiment 2: A single index is used to indicate a frequency band subset. For example, the reference frequency domain area is divided into M (M is a positive integer greater than 1) frequency band subsets, and each frequency band subset is configured with an index. , the indication information in the UL CI may be specifically used to indicate the index of the frequency band subset. When M=1, the UL CI may not include frequency domain indication information (described later).
该实施方式可以用来指示所述参考频域区域的单个频带子集，对于每一个频带子集，UL CI中可以包括有ceil(log2 M)比特的频域指示信息，公式ceil()表示返回大于或等于括号内数值的最小整数。This embodiment can be used to indicate a single frequency band subset of the reference frequency domain area. For each frequency band subset, UL CI can include frequency domain indication information of ceil(log2 M) bits, and the formula ceil() expresses Returns the smallest integer greater than or equal to the value in parentheses.
实施方式三，采用索引和连续的频带子集的数量的方式指示频带子集，例如，参考频域区域被分割为M(M为大于1的正整数)个频带子集，每一个频带子集均配置有索引，这样，UL CI中的频域指示信息可以具体用于指示多个连续的频带子集中的起始频带子集的索引和所述多个连续的频带子集的数量，此时，目标频域资源为上述多个连续的频带子集。Embodiment 3, the frequency band subsets are indicated by index and the number of consecutive frequency band subsets, for example, the reference frequency domain area is divided into M (M is a positive integer greater than 1) frequency band subsets, each frequency band subset Each is configured with an index, so that the frequency domain indication information in the UL CI can be specifically used to indicate the index of the starting frequency band subset in the multiple continuous frequency band subsets and the number of the multiple continuous frequency band subsets, at this time , the target frequency domain resources are the above-mentioned multiple consecutive frequency band subsets.
该实施方式中，UL CI中可以包括有比特的频域指示信息，分别用来指示多个连续的频带子集中的起始频带子集的索引和所述多个连续的频带子集的数量。In this embodiment, the UL CI may include The bit frequency domain indication information is used to respectively indicate the index of the starting frequency band subset among the multiple consecutive frequency band subsets and the number of the multiple consecutive frequency band subsets.
采用实施方式三的目标频域资源指示方法，因频域指示信息的数据量较小，能够节约信令开销。By adopting the target frequency domain resource indication method of Embodiment 3, since the data amount of the frequency domain indication information is small, signaling overhead can be saved.
上述几个实施例介绍的取消上行传输的方法中，接收到的UL CI中包括有频域指示信息，当然接收到的UL CI中还可以不包括(频域指示信息)。In the methods for canceling uplink transmission introduced in the above embodiments, the received UL CI includes frequency domain indication information, and of course the received UL CI may not include (frequency domain indication information).
如图2所示，本发明另一实施例提供一种取消上行传输的方法200，该方法可以由终端设备执行，应用在接收到的UL CI中不包括有频域指示信息的场景下，包括如下步骤：As shown in FIG. 2 , another embodiment of the present invention provides a method 200 for canceling uplink transmission, which can be executed by a terminal device, and is applied in a scenario where the received UL CI does not include frequency domain indication information, including Follow the steps below:
S210：接收上行传输取消指令。S210: Receive an uplink transmission cancel instruction.
该步骤的公开不足之处参见S110。For the shortcomings disclosed in this step, please refer to S110.
S220：若所述上行传输取消指令中不包括频域指示信息，将参考频域区域确定为取消上行传输的目标频域资源。S220: If the uplink transmission cancellation instruction does not include frequency domain indication information, determine a reference frequency domain region as a target frequency domain resource for canceling uplink transmission.
其中，所述参考频域区域为网络设备通过高层信令配置的频域带宽，或，所述参考频域区域为终端设备基于协议确定的频域带宽。Wherein, the reference frequency domain area is a frequency domain bandwidth configured by the network device through high-level signaling, or, the reference frequency domain area is a frequency domain bandwidth determined by the terminal device based on a protocol.
具体地，该处的参考频域区域可以是当前激活的上行BWP；也可以是当前激活的上行BWP中的部分带宽。Specifically, the reference frequency domain area here may be the currently activated uplink BWP; it may also be a part of bandwidth in the currently activated uplink BWP.
终端设备在接收上行传输取消指令时，可以直接将参考频域区域确定为取消上行传输的目标频域资源。When receiving the uplink transmission cancellation instruction, the terminal device may directly determine the reference frequency domain area as the target frequency domain resource for canceling the uplink transmission.
将参考频域区域确定为取消上行传输的目标频域资源之后，还可以暂停或取消在所述目标频域资源上的上行传输。After the reference frequency domain area is determined as the target frequency domain resource for canceling the uplink transmission, the uplink transmission on the target frequency domain resource may also be suspended or cancelled.
上述几个实施例详细介绍了需要取消上行传输的目标频域资源，在实际应用中，在确定出目标频域资源之后，还可以取消上行传输的目标时间区域，根据所述目标时间区域和所述目标频域资源，确定需要取消上行传输的目标时频资源。这样，上述几个实施例提到的暂停或取消在所述目标频域资源上的上行传输，具体可以是暂停或取消在所述目标时频资源上的上行传输。The above-mentioned embodiments have introduced in detail that the target frequency domain resource for uplink transmission needs to be canceled. In practical applications, after the target frequency domain resource is determined, the target time zone for uplink transmission can also be canceled. According to the target time zone and the determined The above target frequency domain resource is used to determine the target time frequency resource for which uplink transmission needs to be canceled. In this way, the suspension or cancellation of the uplink transmission on the target frequency domain resource mentioned in the above several embodiments may specifically suspend or cancel the uplink transmission on the target time-frequency resource.
以下实施例列出了一种取消上行传输的方法300，可以与上述几个方法实施例结合，用于确定出取消上行传输的目标时间区域，如图3所示，包括如下步骤：The following embodiment lists a method 300 for canceling uplink transmission, which can be combined with the above-mentioned several method embodiments to determine the target time zone for canceling uplink transmission, as shown in FIG. 3 , including the following steps:
S310：在接收到上行传输取消指令时，确定第一起始时刻，所述第一起始时刻为参考时间区域的起始时刻。S310: When an uplink transmission cancel instruction is received, determine a first start time, where the first start time is a start time of a reference time zone.
参考时间区域(reference time region)可以是预先设定的用于确定取消上行传输的参考时域资源。参考时间区域通常由第一起始时刻和总长度来确定，下文会结合具体的实施例对确定第一起始时刻和总长度的方式进行说明。The reference time region (reference time region) may be a preset reference time domain resource used for determining to cancel the uplink transmission. The reference time zone is generally determined by the first starting moment and the total length, and the manner of determining the first starting moment and the total length will be described below in conjunction with specific embodiments.
在S310中，具体可以基于上行传输取消指令的接收时刻和预设时间间隔，确定所述第一起始时刻。更为具体的，可以将从所述上行传输取消指令的接收时刻开始经过所述预设时间间隔之后的第一个时隙或第一个符号，确定为所述第一起始时刻。In S310, specifically, the first starting moment may be determined based on the receiving moment of the uplink transmission cancel instruction and a preset time interval. More specifically, the first time slot or the first symbol after the preset time interval elapses from the moment of receiving the uplink transmission cancel instruction may be determined as the first start moment.
UL CI的接收时刻可以是接收携带所述UL CI的下行控制信道(PDCCH)的时隙(slot)，或者UL CI的接收时刻可以是UE接收携带所述UL CI的PDCCH的最后一个时间符号(symbol)，以下简称符号。The receiving moment of the UL CI may be the time slot (slot) for receiving the downlink control channel (PDCCH) carrying the UL CI, or the receiving moment of the UL CI may be the last time symbol ( symbol), hereinafter referred to as symbol.
其中，预设时间间隔可以基于下列方式中的一种来确定：第一种方式，基于所述上行传输取消指令中包含的用于指示所述预设时间间隔的信息，确定所述预设时间间隔；第二种方式，基于用于配置所述预设时间间隔的高层信令(例如，无线资源控制(RadioResource Control，RRC))，确定所述预设时间间隔；第三种方式，基于第一预设值确定所述预设时间间隔，等等。Wherein, the preset time interval may be determined based on one of the following methods: the first method is to determine the preset time based on the information used to indicate the preset time interval included in the uplink transmission cancel instruction interval; the second method is to determine the preset time interval based on high-level signaling (for example, radio resource control (RadioResource Control, RRC)) used to configure the preset time interval; the third method is based on the first A preset value determines the preset time interval, and so on.
对于第一种方式而言，UE可以基于UL CI中指示的时延(offset)来确定上述预设时间间隔，该时延也可以等于K3，K3是相对于UL CI的接收时刻的时长，K3的单位可以是时隙(slot)或符号(symbol)。K3的具体长度与子载波间隔(subcarrier spacing，SCS)有关。可以预先由网络设备通过RRC在UE中配置一个K3集合，并在UL CI中指示K3的实际取值。For the first method, the UE can determine the above preset time interval based on the delay (offset) indicated in the UL CI, and the delay can also be equal to K3, K3 is the duration relative to the receiving moment of the UL CI, K3 The unit of can be slot (slot) or symbol (symbol). The specific length of K3 is related to subcarrier spacing (subcarrier spacing, SCS). A network device may configure a K3 set in UE through RRC in advance, and indicate the actual value of K3 in UL CI.
可选地，如果UL CI是发送给一组UE的，UL CI中指示的K3的长度需要保证收到该UL CI的各UE均有足够的取消时间(cancellation time)，该取消时间可以理解为是UE取消上行传输的处理时间。Optionally, if the UL CI is sent to a group of UEs, the length of K3 indicated in the UL CI needs to ensure that each UE receiving the UL CI has enough cancellation time (cancellation time), and the cancellation time can be understood as is the processing time for the UE to cancel the uplink transmission.
并且，在第一种方式中，可以将从UL CI的接收时刻开始经过K3之后的第一个时隙的边界(boundary)或第一个符号，确定为上述第一起始时刻。Moreover, in the first manner, the boundary (boundary) or the first symbol of the first time slot after K3 from the receiving moment of the UL CI may be determined as the above-mentioned first starting moment.
具体来说，在给定的SCS下，第一起始时刻可以是从UL CI的接收时刻开始经过K3时隙或符号之后的第一个时隙的边界(boundary)。Specifically, under a given SCS, the first starting moment may be the boundary of the first time slot after the K3 time slot or symbol passes from the receiving time of the UL CI.
例如，假设UL CI指示K3＝1个时隙，参考时间区域的总长度为X个时隙，UE在时隙n接收到UL CI，则UE可以将时隙n+1结束的时刻作为第一起始时刻，相应的，将时隙n+1之后开始的X个时隙确定为参考时间区域。For example, assuming that the UL CI indicates K3=1 time slots, the total length of the reference time zone is X time slots, and the UE receives the UL CI in time slot n, then the UE can take the end time of time slot n+1 as the first Correspondingly, the X time slots starting after time slot n+1 are determined as the reference time zone.
又如，假设UL CI指示K3＝7个符号，参考时间区域的总长度为X个时隙，UE在时隙n的符号i(i为一个时隙内符号的编号，i<7,i＝0～13)接收到UL CI，则UE可以将时隙n+1结束的时刻作为第一起始时刻，相应的，将时隙n+1之后开始的X个时隙确定为参考时间区域。As another example, assume that the UL CI indicates K3=7 symbols, the total length of the reference time zone is X time slots, and the symbol i of the UE in time slot n (i is the number of symbols in a time slot, i<7, i= 0-13) After receiving the UL CI, the UE may use the end time slot n+1 as the first start time, and correspondingly determine the X time slots starting after the time slot n+1 as the reference time region.
再如，假设UL CI指示K3＝14个符号，参考时间区域的总长度为X个时隙，UE在时隙n的符号i(i＝0～13)接收到UL CI，则UE可以将时隙n+2结束的时刻作为第一起始时刻，相应的，将时隙n+2之后开始的X个时隙确定为参考时间区域。For another example, assuming that the UL CI indicates K3=14 symbols, the total length of the reference time zone is X time slots, and the UE receives the UL CI at the symbol i (i=0~13) of the time slot n, then the UE can set the time The moment when slot n+2 ends is used as the first starting moment, and correspondingly, X time slots starting after time slot n+2 are determined as the reference time zone.
或者，在给定的SCS下，第一起始时刻可以是从UL CI的接收时刻开始经过K3时隙或符号之后的第一个符号。Or, under a given SCS, the first starting moment may be the first symbol after the K3 time slot or symbol elapses from the receiving moment of the UL CI.
例如，假设UL CI指示K3＝7个符号，参考时间区域的总长度为X个时隙，UE在时隙n的符号i(i<7，i＝0～13)接收到UL CI，则UE可以将时隙n的符号i再加7个符号之后的第一个符号确定为第一起始时刻，相应的，将时隙n的符号i+7个符号之后开始的X个时隙确定为参考时间区域。For example, assuming that the UL CI indicates K3=7 symbols, the total length of the reference time zone is X slots, and the UE receives the UL CI at the symbol i (i<7, i=0~13) of the slot n, then the UE The first symbol after the symbol i of time slot n plus 7 symbols can be determined as the first starting moment, and correspondingly, the X time slots after the symbol i+7 symbols of time slot n can be determined as the reference time zone.
再如，假设UL CI指示K3＝14个符号，参考时间区域的总长度为X个时隙，UE在时隙n的符号i(i＝0～13)接收到UL CI，则UE可以将时隙n+1的符号i之后的第一个符号确定为第一起始时刻，相应的，将时隙n+1的符号i之后开始的X个时隙确定为参考时间区域。For another example, assuming that the UL CI indicates K3=14 symbols, the total length of the reference time zone is X time slots, and the UE receives the UL CI at the symbol i (i=0~13) of the time slot n, then the UE can set the time The first symbol after symbol i of slot n+1 is determined as the first starting moment, and correspondingly, X time slots starting after symbol i of time slot n+1 are determined as the reference time zone.
又如，假设UL CI指示K3＝14个符号，参考时间区域的总长度为Y个符号，UE在时隙n的符号i(i＝0～13)接收到UL CI，则UE可以将时隙n+1的符号i之后的第一个符号确定为第一起始时刻，相应的，将时隙n+1的符号i之后开始的Y个符号确定为参考时间区域。As another example, assuming that the UL CI indicates K3=14 symbols, the total length of the reference time zone is Y symbols, and the UE receives the UL CI at the symbol i (i=0~13) of the time slot n, the UE can assign the time slot The first symbol after symbol i of n+1 is determined as the first start moment, and correspondingly, Y symbols starting after symbol i of time slot n+1 are determined as the reference time zone.
对于第二种方式而言，UE可以基于高层信令(例如RRC)配置的参考时延(reference offset)来确定上述预设时间间隔，该参考时延也可以是相对于UL CI的接收时刻的时长，参考时延的单位可以是时隙(slot)或符号(symbol)。参考时延的具体长度与子载波间隔(subcarrier spacing，SCS)有关。For the second method, the UE can determine the above-mentioned preset time interval based on the reference delay (reference offset) configured by high-level signaling (such as RRC), and the reference delay can also be relative to the receiving moment of the UL CI Duration, the unit of the reference delay can be a slot (slot) or a symbol (symbol). The specific length of the reference delay is related to subcarrier spacing (subcarrier spacing, SCS).
可选地，如果UL CI是发送给一组UE的，则高层信令(例如RRC)配置的参考时延的长度需要保证收到该UL CI的各UE均有足够的取消时间，该取消时间可以理解为是取消上行传输的处理时间。Optionally, if the UL CI is sent to a group of UEs, the length of the reference delay configured by high-layer signaling (such as RRC) needs to ensure that each UE receiving the UL CI has enough cancellation time, and the cancellation time It can be understood as the processing time for canceling uplink transmission.
进一步地，网络设备可以选择将UL CI发送给一组处理能力相同的UE，例如发送给一组最小取消时间长度相同，以及上行定时提前(timing advance，TA)的值相同的UE，这样高层信令可以向该组中的各UE配置相同的参考时延，这对网络设备来说更为简单易行。如果网络设备将UL CI发送给一组处理能力不同的UE(例如TA不同的一组UE)，则网络设备在向该组中的各UE配置参考时延时，需要考虑该组UE中TA的值最大的UE也有足够的取消时间。Further, the network device may choose to send the UL CI to a group of UEs with the same processing capability, for example, to a group of UEs with the same minimum cancellation time length and the same uplink timing advance (timing advance, TA) value, so that high-level information Therefore, the same reference delay can be configured for each UE in the group, which is simpler and easier for network devices. If the network device sends the UL CI to a group of UEs with different processing capabilities (for example, a group of UEs with different TAs), the network device needs to consider the TAs in the group of UEs when configuring the reference time delay for each UE in the group. The UE with the largest value also has enough cancellation time.
下面对TA进行简要的介绍。在小区内，由于不同UE所处的位置可能不同，距离基站的距离也可能各不相同。因此，基站与UE之间的信号会经历不同的传输时延。为了保证基站在接收来自不同UE的上行信号时保持定时是对齐的，UE需要在发送上行信号时，基于下行定时增加一个偏移，该偏移值即为TA值，通常由基站来配置。基站通过TA可以控制不同UE的上行传输提前量。对于距离基站较近的UE，传输时延较小，可配置较小的TA；对于距离基站较远的UE，所经历的传输时延较大，需要配置较大的TA。A brief introduction to TA is given below. In a cell, since different UEs may have different locations, the distances from the base station may also be different. Therefore, signals between the base station and the UE experience different transmission delays. In order to ensure that the base station keeps the timing aligned when receiving uplink signals from different UEs, the UE needs to add an offset based on the downlink timing when sending uplink signals. The offset value is the TA value, which is usually configured by the base station. The base station can control the uplink transmission advances of different UEs through the TA. For a UE that is closer to the base station, the transmission delay is small, and a smaller TA can be configured; for a UE that is farther from the base station, the transmission delay experienced is greater, and a larger TA needs to be configured.
在第二种方式中，可以将从UL CI的接收时刻开始经过参考时延之后的第一个时隙的边界或第一个符号，确定为上述第一起始时刻。In the second manner, the boundary of the first time slot or the first symbol after the reference time delay from the receiving moment of the UL CI may be determined as the above-mentioned first starting moment.
具体来说，在给定的SCS下，可以将从UL CI的接收时刻开始经过参考时延之后的第一个时隙的边界，确定为上述第一起始时刻。Specifically, under a given SCS, the boundary of the first time slot after the reference time delay from the receiving time of the UL CI may be determined as the above-mentioned first starting time.
例如，假设RRC配置的参考时延为1个时隙，参考时间区域的总长度为X个时隙，UE在时隙n接收到UL CI，则UE可以将时隙n+1结束的时刻作为第一起始时刻，相应的，将时隙n+1之后开始的X个时隙确定为参考时间区域。For example, assuming that the reference delay configured by RRC is 1 time slot, the total length of the reference time zone is X time slots, and the UE receives UL CI in time slot n, then the UE can use the end time of time slot n+1 as Correspondingly, at the first starting moment, the X time slots starting after the time slot n+1 are determined as the reference time zone.
又如，假设RRC配置的参考时延为7个符号，参考时间区域的总长度为X个时隙，UE在时隙n的符号i(i<7，i＝0～13)接收到UL CI，则UE可以将时隙n+1结束的时刻作为第一起始时刻，相应的，将时隙n+1之后开始的X个时隙确定为参考时间区域。As another example, assume that the reference delay configured by RRC is 7 symbols, and the total length of the reference time zone is X slots, and the UE receives UL CI at symbol i (i<7, i=0~13) of slot n , then the UE may use the time when the time slot n+1 ends as the first starting time, and correspondingly, determine the X time slots starting after the time slot n+1 as the reference time region.
再如，假设RRC配置的参考时延为14个符号，参考时间区域的总长度为X个时隙，UE在时隙n的符号i(i＝0～13)接收到UL CI，则UE可以将时隙n+2结束的时刻作为第一起始时刻，相应的，将时隙n+2之后开始的X个时隙确定为参考时间区域。For another example, assuming that the reference delay configured by RRC is 14 symbols, the total length of the reference time zone is X slots, and the UE receives UL CI at symbol i (i=0~13) of slot n, then the UE can The time when time slot n+2 ends is taken as the first start time, and correspondingly, X time slots starting after time slot n+2 are determined as the reference time zone.
或者，在给定的SCS下，第一起始时刻可以是从UL CI的接收时刻开始经过参考时延之后的第一个符号。Or, under a given SCS, the first starting moment may be the first symbol after a reference time delay from the receiving moment of the UL CI.
例如，假设RRC配置的参考时延为7个符号，参考时间区域的总长度为X个时隙，UE在时隙n的符号i(i<7，i＝0～13)接收到UL CI，则UE可以将时隙n的符号i再加7个符号之后的第一个符号确定为第一起始时刻，相应的，将时隙n的符号i再加7个符号之后开始的X个时隙确定为参考时间区域。For example, assuming that the reference delay configured by RRC is 7 symbols, the total length of the reference time zone is X slots, and the UE receives UL CI at symbol i (i<7, i=0~13) of slot n, Then the UE can determine the first symbol after the symbol i of the time slot n plus 7 symbols as the first start time, and correspondingly, add the symbol i of the time slot n plus 7 symbols to start X time slots Determined as the reference time zone.
再如，假设RRC配置的参考时延为14个符号，参考时间区域的总长度为X个时隙，UE在时隙n的符号i(i＝0～13)接收到UL CI，则UE可以将时隙n+1的符号i之后的第一个符号确定为第一起始时刻，相应的，将时隙n+1的符号i之后开始的X个时隙确定为参考时间区域。For another example, assuming that the reference delay configured by RRC is 14 symbols, the total length of the reference time zone is X slots, and the UE receives UL CI at symbol i (i=0~13) of slot n, then the UE can The first symbol after symbol i of time slot n+1 is determined as the first starting moment, and correspondingly, X time slots starting after symbol i of time slot n+1 are determined as the reference time zone.
又如，假设RRC配置的参考时延为14个符号，参考时间区域的总长度为Y个符号，UE在时隙n的符号i(i＝0～13)接收到UL CI，则UE可以将时隙n+1的符号i之后的第一个符号确定为第一起始时刻，相应的，将时隙n+1的符号i之后开始的Y个符号确定为参考时间区域。As another example, assuming that the reference delay configured by RRC is 14 symbols, the total length of the reference time zone is Y symbols, and the UE receives UL CI at symbol i (i=0~13) of time slot n, then the UE can set The first symbol after symbol i of time slot n+1 is determined as the first starting moment, and correspondingly, Y symbols starting after symbol i of time slot n+1 are determined as the reference time zone.
对于第三种方式而言，UE可以基于设定的最小取消时间(minimum cancellationtime)确定上述预设时间间隔，也即第一预设值可以为最小取消时间。最小取消时间，可以理解为是UE能够取消上行传输所需的最短处理时间，它的大小与UE的能力和SCS有关，一般而言，UE的能力越强，最小取消时间越短，反之，最小取消时间越长。最小取消时间的单位为时隙或符号。For the third manner, the UE may determine the above preset time interval based on a set minimum cancellation time (minimum cancellation time), that is, the first preset value may be the minimum cancellation time. The minimum cancellation time can be understood as the minimum processing time required for the UE to cancel the uplink transmission. Its size is related to the capability of the UE and the SCS. Generally speaking, the stronger the capability of the UE, the shorter the minimum cancellation time. Conversely, the minimum The longer it takes to cancel. The unit of minimum cancel time is slot or symbol.
最小取消时间既可以是协议预定的，也可以是网络设备给UE配置的。一般情况下，最小取消时间中不包括TA。The minimum cancellation time may be predetermined by the protocol, or configured by the network equipment for the UE. Generally, TA is not included in the minimum cancellation time.
当第一预设值为最小取消时间时，第三种方式具体可以包括：根据上行定时提前的值和所述最小取消时间，确定所述预设时间间隔。更为具体的，可以将上行定时提前的值和所述最小取消时间的和(minimum cancellation time+TA)，确定为上述预设时间间隔。并且，可以将从UL CI的接收时刻开始经过最小取消时间+TA之后的第一个时隙的边界或第一个符号，确定为上述第一起始时刻。When the first preset value is the minimum cancellation time, the third manner may specifically include: determining the preset time interval according to the uplink timing advance value and the minimum cancellation time. More specifically, the sum of the uplink timing advance value and the minimum cancellation time (minimum cancellation time+TA) may be determined as the aforementioned preset time interval. Also, the boundary of the first time slot or the first symbol after the minimum cancellation time+TA elapses from the receiving moment of the UL CI may be determined as the above-mentioned first starting moment.
在上述确定预设时间间隔的第三种方式中，TA值可以是UE专有的TA值(UE-specific TA)；TA值也可以是UE所在用户组(UE group)中所有UE的TA值中的最大值，且该最大值可以通过RRC的配置得到；TA值还可以是一个设定的参考TA(reference TA)值，例如可配置的最大的TA值。In the third way of determining the preset time interval above, the TA value can be a UE-specific TA value (UE-specific TA); the TA value can also be the TA value of all UEs in the user group (UE group) where the UE belongs , and the maximum value can be obtained through RRC configuration; the TA value can also be a set reference TA (reference TA) value, such as a configurable maximum TA value.
具体来说，在给定的SCS下，可以将从UL CI的接收时刻开始经过最小取消时间+TA之后的第一个时隙的边界，确定为上述第一起始时刻。Specifically, under a given SCS, the boundary of the first time slot after the minimum cancellation time + TA elapses from the receiving moment of the UL CI may be determined as the above-mentioned first starting moment.
例如，假设最小取消时间等于10个符号，参考时间区域的总长度为X个时隙，TA为4个符号，最小取消时间+TA＝14个符号，UE在时隙n的符号i＝7(i＝7～13)接收到UL CI，则UE可以将时隙n+2结束的时刻作为第一起始时刻，相应的，将时隙n+2之后开始的X个时隙确定为参考时间区域。For example, assuming that the minimum cancellation time is equal to 10 symbols, the total length of the reference time zone is X time slots, TA is 4 symbols, the minimum cancellation time+TA=14 symbols, and the symbol i=7( i=7~13) After receiving UL CI, the UE can use the time when slot n+2 ends as the first starting time, and correspondingly, determine the X slots starting after slot n+2 as the reference time zone .
或者，在给定的SCS下，可以将从UL CI的接收时刻开始经过最小取消时间+TA之后的第一个符号，确定为上述第一起始时刻。Alternatively, under a given SCS, the first symbol after the minimum cancellation time+TA elapses from the receiving moment of the UL CI may be determined as the above-mentioned first starting moment.
例如，假设最小取消时间等于10个符号，参考时间区域的总长度为X个时隙，TA为4个符号，最小取消时间+TA＝14个符号，UE在时隙n的符号i(i＝0～13)接收到UL CI，则UE可以将时隙n+m的符号j之后的第一个符号作为第一起始时刻，相应的，将时隙n+m的符号j之后开始的X个时隙确定为参考时间区域。其中，m＝floor((i+最小取消时间+TA)/14)，j＝mod(i+最小取消时间+TA，14)，函数floor表示向下取整，函数mod()表示取余数。For example, assuming that the minimum cancellation time is equal to 10 symbols, the total length of the reference time zone is X slots, TA is 4 symbols, the minimum cancellation time+TA=14 symbols, and the symbol i (i= 0~13) After receiving the UL CI, the UE can use the first symbol after the symbol j of the slot n+m as the first start time, and correspondingly, the X symbols starting after the symbol j of the slot n+m A time slot is determined as a reference time zone. Among them, m=floor((i+minimum cancellation time+TA)/14), j=mod(i+minimum cancellation time+TA, 14), the function floor means rounding down, and the function mod() means taking the remainder.
或者，在给定的SCS下，当TA具体为group-specific TA(UE组专属TA)时，可以将从UL CI的接收时刻开始经过最小取消时间+UE组专属TA之后的第一个时隙的边界或第一个符号，确定为上述第一起始时刻。Or, under a given SCS, when the TA is specifically a group-specific TA (UE group-specific TA), the first time slot after the minimum cancellation time + the UE group-specific TA can be set from the receiving moment of the UL CI The boundary of , or the first symbol, is determined as the above-mentioned first starting moment.
具体而言，当多个UE配置了检测同一个UL CI时，TA可以为网络设备配置的UE组专属TA，且该UE组专属TA能够使同一个UE组内所有的UE具备足够的取消时间(cancellationtime)。例如，UE组专属TA可以为该UE组内所有UE的TA值中的最大值。Specifically, when multiple UEs are configured to detect the same UL CI, the TA can be a UE group-specific TA configured by the network device, and the UE group-specific TA can enable all UEs in the same UE group to have sufficient cancellation time (cancellation time). For example, the UE group-specific TA may be the maximum value among TA values of all UEs in the UE group.
或者，在给定的SCS下，当TA具体为参考TA(reference TA)时，可以将从UL CI的接收时刻开始经过最小取消时间+参考TA之后的第一个时隙的边界或第一个符号，确定为上述第一起始时刻。Or, under a given SCS, when the TA is specifically a reference TA (reference TA), the boundary of the first time slot or the first symbol, determined as the above-mentioned first starting moment.
具体而言，当多个UE配置了检测同一个UL CI时，TA可以为网络设备配置的参考TA，且该参考TA能够使同一个UE组内所有的UE具备足够的取消时间(cancellation time)。例如，参考TA可以为可配置的TA值中的最大值。Specifically, when multiple UEs are configured to detect the same UL CI, the TA can be a reference TA configured by the network device, and the reference TA can enable all UEs in the same UE group to have sufficient cancellation time (cancellation time) . For example, the reference TA may be the maximum value among configurable TA values.
S320：基于所述第一起始时刻，确定取消上行传输的目标时间区域。S320: Based on the first starting moment, determine a target time zone for canceling uplink transmission.
目标时间区域，可以理解为是欲取消上行传输的时间区域，目标时间区域通常位于S310中所述的参考时间区域之内。The target time zone can be understood as the time zone where the uplink transmission is to be canceled, and the target time zone is usually located within the reference time zone described in S310.
可选地，在S320中确定出目标时间区域之后，本发明实施例提供的一种取消上行传输的方法还可以包括：暂停或取消在所述目标时间区域上的上行传输。当然，在实际应用中，如果UL CI的接收时刻与目标时间区域之间没有足够的取消时间(cancellationtime)，则UE可以忽略该UL CI，一般情况下，取消时间＝最小取消时间+TA，TA为UE当前由网络指示或配置的TA。Optionally, after the target time zone is determined in S320, the method for canceling uplink transmission provided by the embodiment of the present invention may further include: suspending or canceling uplink transmission in the target time zone. Of course, in practical applications, if there is not enough cancellation time (cancellation time) between the receiving moment of the UL CI and the target time zone, the UE can ignore the UL CI. In general, cancellation time = minimum cancellation time + TA, TA It is the TA currently indicated or configured by the network for the UE.
下面对S320的可能的几种具体实施方式进行说明。Several possible specific implementation manners of S320 are described below.
在第一种实施方式中，在步骤S320之前，本发明实施例提供的一种取消上行传输的方法还可以包括：确定所述参考时间区域的总长度。相应的，上述步骤S320具体可以包括：基于所述总长度和所述第一起始时刻，确定所述目标时间区域。In the first implementation manner, before step S320, the method for canceling uplink transmission provided by the embodiment of the present invention may further include: determining the total length of the reference time zone. Correspondingly, the above step S320 may specifically include: determining the target time zone based on the total length and the first starting moment.
示例性地，参考时间区域的总长度可以基于下列方式中的一种来确定：Exemplarily, the total length of the reference time zone may be determined based on one of the following methods:
一是，基于用于配置所述总长度的高层信令(例如RRC)，确定所述总长度。总长度L的单位可以是时隙或符号，L的取值与上行(Uplink，UL)带宽部分(bandwidth part，BWP)的数值配置(numerology)有关，如果总长度L的单位为时隙，则L的取值可以是1、2、4、5等，如果总长度L的单位为符号，L的取值可以为7、14、28符号等。One is to determine the total length based on high layer signaling (for example, RRC) used to configure the total length. The unit of the total length L can be a time slot or a symbol, and the value of L is related to the numerical configuration (numerology) of the uplink (Uplink, UL) bandwidth part (bandwidth part, BWP). If the unit of the total length L is a time slot, then The value of L can be 1, 2, 4, 5, etc. If the unit of the total length L is a symbol, the value of L can be 7, 14, 28 symbols, etc.
二是，基于所述上行传输取消指令的检测周期(monitoring periodicity)确定所述总长度。如果UL CI的检测周期为X个时隙或Y个符号，那么参考时间区域的总长度也可以为X个时隙或Y个符号。UL CI的检测周期的取值可以是7个符号、1个时隙、2个时隙，等等。The second is to determine the total length based on a monitoring period of the uplink transmission cancel command. If the detection period of the UL CI is X slots or Y symbols, the total length of the reference time region may also be X slots or Y symbols. The value of the detection period of the UL CI may be 7 symbols, 1 time slot, 2 time slots, and so on.
三是，基于第二预设值确定所述总长度，也即参考时间区域的长度可以是固定值，例如1个时隙。Third, the total length is determined based on a second preset value, that is, the length of the reference time region may be a fixed value, such as 1 time slot.
更为具体的，在S320中，可以将从所述第一起始时刻开始经过所述总长度的时间区域，确定为所述目标时间区域，也即将所述参考时间区域确定为所述目标时间区域。More specifically, in S320, the time zone that passes through the total length from the first starting moment may be determined as the target time zone, that is, the reference time zone is determined as the target time zone .
例如，假设已知参考时间区域的起始时刻(第一起始时刻)和总长度，且UL CI中不包括取消上行传输的目标起始时刻信息和目标长度信息，也即ULCI不指示参考时间区域内的cancelled slot/symbol(s)，则UE可以将参考时间区域确定为取消上行传输的目标时间区域，并取消目标时间区域上的上行传输。For example, assume that the start time (first start time) and total length of the reference time zone are known, and the UL CI does not include the target start time information and target length information for canceling uplink transmission, that is, the ULCI does not indicate the reference time zone canceled slot/symbol(s), the UE may determine the reference time zone as the target time zone for canceling the uplink transmission, and cancel the uplink transmission in the target time zone.
具体如图4所示，假设UE根据UL CI的指示确定出K3＝1个时隙，参考时间区域的总长度为1个时隙，UE在时隙n接收到UL CI(图4中的12)，则UE可以确定出第一起始时刻t1为从时隙n开始经过K3之后的第一个时隙的起始时刻(边界)，参考时间区域为时隙n+1(图4中的21)，UE可以取消在参考时间区域21(时隙n+1)上的上行eMBB业务传输。Specifically as shown in FIG. 4 , assuming that the UE determines that K3=1 time slot according to the indication of the UL CI, the total length of the reference time region is 1 time slot, and the UE receives the UL CI in time slot n (12 in FIG. 4 ), then the UE can determine that the first starting moment t1 is the starting moment (boundary) of the first time slot after passing through K3 from time slot n, and the reference time area is time slot n+1 (21 in FIG. 4 ), the UE may cancel the uplink eMBB service transmission in the reference time zone 21 (time slot n+1).
在具体实现时，网络设备可以通过RRC信令预先在UE中配置(configured)一个如下表1所示的K3集合，UL CI指示该表中的一个编号(index)，UE通过该编号查询表1就可以确定出具体的K3值。需要说明的是，网络设备通过UL CI指示K3时，要考虑UE的能力。In specific implementation, the network device can pre-configure (configured) a K3 set in the UE through RRC signaling as shown in Table 1 below. The UL CI indicates an index in the table, and the UE queries Table 1 through the index. The specific K3 value can be determined. It should be noted that when the network device indicates K3 through the UL CI, the capability of the UE should be considered.
表1Table 1

再如图5所示，假设UE根据UL CI的指示确定出K3＝14个符号，参考时间区域的总长度为Y个符号，UE在时隙n的符号i(i＝0～13)接收到UL CI(图5中的12)，则UE可以确定出第一起始时刻t1为从时隙n开始经过K3之后的第一个符号，参考时间区域为时隙n+1的符号i开始的Y个符号(图5中的21)，UE可以取消在参考时间区域21上的上行eMBB业务传输(图5中填充图样为附图标记23所指的部分)。As shown in Figure 5 again, suppose the UE determines K3=14 symbols according to the indication of the UL CI, the total length of the reference time zone is Y symbols, and the UE receives the UL CI (12 in Figure 5), the UE can determine that the first starting time t1 is the first symbol after K3 from time slot n, and the reference time zone is Y starting from symbol i of time slot n+1 symbol (21 in FIG. 5), the UE may cancel the uplink eMBB service transmission on the reference time zone 21 (the filling pattern in FIG. 5 is the part indicated by reference numeral 23).

表2Table 2
在第二种实施方式中，在步骤S320之前，本发明实施例提供的一种取消上行传输的方法还可以包括：确定所述参考时间区域的总长度。相应的，上述步骤S320具体可以包括：基于所述总长度和所述第一起始时刻，确定所述目标时间区域。并且，UL CI中包括用于指示取消上行传输的时域资源的目标起始时刻信息，则本发明实施例提供的一种取消上行传输的方法还可以包括：基于所述第一起始时刻和所述目标起始时刻信息，确定取消上行传输的第二起始时刻。第二起始时刻是相对于第一起始时刻而言的，通常情况下，第二起始时刻晚于或等于上述第一起始时刻。In the second implementation manner, before step S320, the method for canceling uplink transmission provided by the embodiment of the present invention may further include: determining the total length of the reference time zone. Correspondingly, the above step S320 may specifically include: determining the target time zone based on the total length and the first starting moment. In addition, the UL CI includes target start time information for indicating the time domain resources for canceling the uplink transmission, then a method for canceling the uplink transmission provided by the embodiment of the present invention may further include: based on the first start time and the The target start time information is used to determine the second start time for canceling the uplink transmission. The second starting moment is relative to the first starting moment, and generally, the second starting moment is later than or equal to the above-mentioned first starting moment.
相应的，上述基于所述总长度和所述第一起始时刻，确定所述目标时间区域，具体可以包括：基于所述总长度和所述第一起始时刻确定所述参考时间区域的结束时刻；将从所述第二起始时刻开始至所述结束时刻之间的时间区域，确定为所述目标时间区域。Correspondingly, the above-mentioned determining the target time zone based on the total length and the first start time may specifically include: determining the end time of the reference time zone based on the total length and the first start time; A time zone from the second start time to the end time is determined as the target time zone.
例如，假设已知参考时间区域的起始时刻(第一起始时刻)和总长度，ULCI对取消上行传输的目标起始时刻信息(第二起始时刻)做出进一步地指示，也即UL CI指示参考时间区域内的cancelled slot/symbol(s)，则UE可以从第二起始时刻开始至参考时间区域的结束时刻之间的时间区域确定为目标时间区域，并取消目标时间区域上的上行传输。For example, assuming that the start time (first start time) and total length of the reference time zone are known, the ULCI further indicates the target start time information (second start time) for canceling uplink transmission, that is, the UL CI Indicate the canceled slot/symbol(s) in the reference time zone, then the UE can determine the time zone between the second start time and the end time of the reference time zone as the target time zone, and cancel the uplink on the target time zone transmission.
具体而言，UL CI可以用一个比特区域(bit-field)指示第二起始时刻(startingsymbol)，该比特区域的大小(Bit-field size)可以为：Bit-field size＝ceil(log2(Nsymbol*X/Nbundle_size))，其中，X表示参考时间区域的总时隙数，Nsymbol表示一个时隙内的符号数；Nbundle_size表示子区域的大小(或者符号组合的大小(symbol bundle size))，也可以称为子区域的符号数，Nbundle_size可以理解为是子区域的粒度，下文会对子区域(或者符号组合)进行单独说明，此处暂不赘述。Specifically, the UL CI may use a bit field (bit-field) to indicate the second starting moment (starting symbol), and the size of the bit field (Bit-field size) may be: Bit-field size=ceil(log2(Nsymbol *X/Nbundle_size )), where X represents the total number of time slots in the reference time zone, Nsymbol represents the number of symbols in a time slot; Nbundle_size represents the size of the sub-region (or the size of the symbol bundle (symbol bundle size )), can also be referred to as the number of symbols in a sub-region, and Nbundle_size can be understood as the granularity of a sub-region. The sub-region (or combination of symbols) will be described separately below, and will not be described here.
如图6所示，假设UE根据UL CI的指示确定出K3＝1个时隙，参考时间区域的总长度为1个时隙(X＝1)，UE在时隙n接收到UL CI(图6中的12)，则UE可以确定出第一起始时刻t1为从时隙n开始经过K3之后的第一个时隙的边界，参考时间区域为时隙n+1(图6中的21)。并且，假设UL CI进一步指示第二起始时刻t2为第一起始时刻t1之后的第5个符号(startingsymbol为5)，UL CI中用于指示t1的比特区域的大小为：Bit-field size＝ceil(log2(Nsymbol))，子区域的粒度为1个符号。则UE可以将时隙n+1中的符号5至符号13之间的时间区域确定为目标时间区域，并取消在时隙n+1中的符号5至符号13之间的时间区域上的上行eMBB业务传输(图6中填充图样为附图标记23所指的部分)。As shown in Figure 6, assuming that the UE determines K3 = 1 time slot according to the indication of the UL CI, the total length of the reference time region is 1 time slot (X = 1), and the UE receives the UL CI in the time slot n (Fig. 6 in 12), then the UE can determine that the first starting time t1 is the boundary of the first time slot after passing through K3 from time slot n, and the reference time area is time slot n+1 (21 in Figure 6) . And, assuming that the UL CI further indicates that the second starting time t2 is the fifth symbol after the first starting time t1 (startingsymbol is 5), the size of the bit field used to indicate t1 in the UL CI is: Bit-field size= ceil(log2(Nsymbol )), the granularity of the subregion is 1 symbol. Then the UE may determine the time zone between symbol 5 and symbol 13 in slot n+1 as the target time zone, and cancel the uplink in the time zone between symbol 5 and symbol 13 in slot n+1 eMBB service transmission (the filling pattern in FIG. 6 is the part indicated by reference numeral 23 ).
再如图7所示，假设UE根据UL CI的指示确定出K3＝1个时隙，参考时间区域的总长度为1个时隙(X＝1)，UE在时隙n接收到UL CI(图7中的12)，则UE可以确定出第一起始时刻t1为从时隙n开始经过K3之后的第一个时隙的边界，参考时间区域为时隙n+1(图7中的21)。并且，假设UL CI进一步指示第二起始时刻t2为第一起始时刻t1之后的第4个符号(starting symbol为4)，UL CI中用于指示t1的比特区域的大小为：Bit-field size＝ceil(log2(Nsymbol/2))，子区域的粒度为2个符号。则UE可以将时隙n+1中的符号4至符号13之间的时间区域确定为目标时间区域，并取消在时隙n+1中的符号4至符号13之间的时间区域上的上行eMBB业务传输(图7中填充图样为23的部分)。As shown in FIG. 7 , assuming that the UE determines K3=1 time slot according to the indication of the UL CI, the total length of the reference time region is 1 time slot (X=1), and the UE receives the UL CI in the time slot n ( 12) in FIG. 7 , then the UE can determine that the first starting time t1 is the boundary of the first time slot after passing through K3 from time slot n, and the reference time area is time slot n+1 (21 in FIG. 7 ). And, assuming that the UL CI further indicates that the second start time t2 is the fourth symbol after the first start time t1 (starting symbol is 4), the size of the bit area used to indicate t1 in the UL CI is: Bit-field size =ceil(log2(Nsymbol /2)), the granularity of the sub-region is 2 symbols. Then the UE may determine the time zone between symbol 4 and symbol 13 in slot n+1 as the target time zone, and cancel the uplink in the time zone between symbol 4 and symbol 13 in slot n+1 eMBB service transmission (the part filled with pattern 23 in FIG. 7 ).
再如图8所示，假设UE根据最小取消时间(tmin＝10个符号)和TA(2个符号)确定出预设时间间隔为12个符号，参考时间区域的总长度为1个时隙(X＝1)，UE在时隙n的第1个符号接收到UL CI(图8中的12)，则UE可以确定出第一起始时刻t1为从时隙n的第1个符号开始经过12个符号之后的第一个时隙的边界，参考时间区域为时隙n+1(图8中的21)。并且，假设UL CI进一步指示第二起始时刻t2为第一起始时刻t1之后的第4个符号(starting symbol为4)，UL CI中用于指示t1的比特区域的大小为：Bit-field size＝ceil(log2(Nsymbol/2))，子区域的粒度为2个符号。则UE可以将时隙n+1中的符号4至符号13之间的时间区域确定为目标时间区域，并取消在时隙n+1中的符号4至符号13之间的时间区域上的上行eMBB业务传输(图8中填充图样为附图标记23所指的部分)。As shown in Figure 8, assume that the UE determines that the preset time interval is 12 symbols according to the minimum cancellation time (tmin = 10 symbols) and TA (2 symbols), and the total length of the reference time region is 1 time slot (X=1), the UE receives the UL CI (12 in Figure 8) at the first symbol of slot n, then the UE can determine that the first starting time t1 is passed from the first symbol of slot n The boundary of the first time slot after 12 symbols, the reference time zone is time slot n+1 (21 in FIG. 8 ). And, assuming that the UL CI further indicates that the second start time t2 is the fourth symbol after the first start time t1 (starting symbol is 4), the size of the bit area used to indicate t1 in the UL CI is: Bit-field size =ceil(log2(Nsymbol /2)), the granularity of the sub-region is 2 symbols. Then the UE may determine the time zone between symbol 4 and symbol 13 in slot n+1 as the target time zone, and cancel the uplink in the time zone between symbol 4 and symbol 13 in slot n+1 eMBB service transmission (the filling pattern in FIG. 8 is the part indicated by reference numeral 23 ).
再如图9所示，假设UE根据最小取消时间(tmin＝10个符号)和TA(2个符号)确定出预设时间间隔为12个符号，参考时间区域的总长度为Y个符号，UE在时隙n的第1个符号接收到UL CI(图9中的12)，则UE可以确定出第一起始时刻t1为从时隙n的第1个符号开始经过12个符号之后的第1个符号，参考时间区域为第一起始时刻t1开始的Y个符号(图9中的21)。并且，假设UL CI进一步指示第二起始时刻t2为第一起始时刻t1之后的第5个符号(startingsymbol为5)，UL CI中用于指示t1的比特区域的大小为：Bit-field size＝ceil(log2(Y/2))，子区域的粒度为2个符号。则UE可以将第一起始时刻t1之后的第5个符号至第一起始时刻t1之后的第Y个符号之间的时间区域确定为目标时间区域，并取消在目标时间区域上的上行eMBB业务传输(图9中填充图样为附图标记23所指的部分)。As shown in FIG. 9 again, assuming that the UE determines that the preset time interval is 12 symbols according to the minimum cancellation time (tmin = 10 symbols) and TA (2 symbols), and the total length of the reference time zone is Y symbols, When the UE receives the UL CI (12 in Figure 9) at the first symbol of slot n, the UE can determine that the first starting time t1 is the first symbol after 12 symbols from the first symbol of slot n 1 symbol, and the reference time zone is Y symbols starting from the first start time t1 (21 in FIG. 9 ). And, assuming that the UL CI further indicates that the second starting time t2 is the fifth symbol after the first starting time t1 (startingsymbol is 5), the size of the bit field used to indicate t1 in the UL CI is: Bit-field size= ceil(log2(Y/2)), the granularity of subregions is 2 symbols. Then the UE can determine the time zone between the 5th symbol after the first start time t1 and the Y-th symbol after the first start time t1 as the target time zone, and cancel the uplink eMBB service transmission in the target time zone (The filling pattern in FIG. 9 is the part indicated by reference numeral 23).
在第三种实施方式中，在步骤S320之前，本发明实施例提供的一种取消上行传输的方法还可以包括：确定所述参考时间区域的总长度。相应的，上述步骤S320具体可以包括：基于所述总长度和所述第一起始时刻，确定所述目标时间区域。并且，UL CI中包括用于指示取消上行传输的时域资源的目标起始时刻信息和目标长度信息(cancelled slot/symbol)，则本发明实施例提供的一种取消上行传输的方法还可以包括：基于所述第一起始时刻和所述目标起始时刻信息，确定取消上行传输的第二起始时刻；基于所述目标长度信息，确定取消上行传输的目标长度。第二起始时刻是相对于第一起始时刻而言的，通常情况下，第二起始时刻晚于或等于上述第一起始时刻。In the third implementation manner, before step S320, the method for canceling uplink transmission provided by the embodiment of the present invention may further include: determining the total length of the reference time zone. Correspondingly, the above step S320 may specifically include: determining the target time zone based on the total length and the first starting moment. In addition, the UL CI includes target start time information and target length information (cancelled slot/symbol) used to indicate the time-domain resource for canceling uplink transmission, then a method for canceling uplink transmission provided by the embodiment of the present invention may further include : Determine a second start time for canceling uplink transmission based on the first start time and the target start time information; determine a target length for canceling uplink transmission based on the target length information. The second starting moment is relative to the first starting moment, and generally, the second starting moment is later than or equal to the above-mentioned first starting moment.
相应的，上述步骤S320具体可以包括：将从所述第二起始时刻开始经过所述目标长度的时间区域，确定为所述目标时间区域，并暂停或取消在目标时间区域上的上行eMBB业务传输。通常情况下，依照该方式确定的目标时间区域位于上述参考时间区域内。Correspondingly, the above-mentioned step S320 may specifically include: determining the time zone passing the target length from the second starting moment as the target time zone, and suspending or canceling the uplink eMBB service in the target time zone transmission. Usually, the target time zone determined in this manner is located within the aforementioned reference time zone.
具体而言，UL CI可以用一个比特区域(bit-field)指示第二起始时刻和目标长度(start and length indicator，SLIV)，目标长度不超过参考区域的总长度，该比特区域的大小(Bit-field size)可以为：Bit-field size＝ceil(log2(Nsymbol*X/Nbundle_size)*(Nsymbol*X/Nbundle_size+1)/2)，其中，X表示参考时间区域的总时隙数，Nsymbol表示一个时隙内的符号数；Nbundle_size表示子区域的大小(或者符号组合的大小(symbol bundle size))，也可以称为子区域的符号数，Nbundle_size可以理解为是子区域的粒度，下文会对子区域(或者符号组合)进行单独说明，此处暂不赘述。Specifically, the UL CI may use a bit field (bit-field) to indicate the second start moment and a target length (start and length indicator, SLIV), the target length does not exceed the total length of the reference field, and the size of the bit field ( Bit-field size) can be: Bit-field size=ceil(log2(Nsymbol *X/Nbundle_size )*(Nsymbol *X/Nbundle_size +1)/2), where X represents the total The number of time slots, Nsymbol represents the number of symbols in a time slot; Nbundle_size represents the size of the sub-region (or the size of the symbol bundle size (symbol bundle size)), which can also be called the number of symbols in the sub-region, Nbundle_size can be understood as is the granularity of the sub-area, and the sub-area (or combination of symbols) will be described separately below, and will not be described here.
如图10所示，假设UE根据UL CI的指示确定出K3＝1个时隙，参考时间区域的总长度为1个时隙(X＝1)，UE在时隙n接收到UL CI(图10中的12)，UE将从时隙n开始经过K3之后的第一个时隙的边界确定为第一起始时刻t1，将时隙n+1确定为参考时间区域(图10中的21)。并且，假设UL CI进一步指示第二起始时刻t2为第一起始时刻t1之后的第5个符号(starting symbol为5)，目标长度T为3个符号，UL CI中用于指示t1和T的比特区域的大小为：Bit-field＝ceil(log2(Nsymbol*(Nsymbol+1)/2))，子区域的粒度为1个符号。则UE可以将时隙n+1中的符号5至符号8之间的时间区域确定为目标时间区域，并取消在时隙n+1中的符号5至符号8之间的时间区域上的上行eMBB业务传输(图10中填充图样为附图标记23所指的部分)。As shown in Figure 10, assuming that the UE determines K3 = 1 time slot according to the indication of the UL CI, the total length of the reference time region is 1 time slot (X = 1), and the UE receives the UL CI in the time slot n (Fig. 12) in 10, the UE determines the boundary of the first time slot after K3 from time slot n as the first starting time t1, and determines time slot n+1 as the reference time area (21 in Figure 10) . And, assuming that the UL CI further indicates that the second starting moment t2 is the fifth symbol (starting symbol is 5) after the first starting moment t1, and the target length T is 3 symbols, the UL CI used to indicate t1 and T The size of the bit field is: Bit-field=ceil(log2(Nsymbol *(Nsymbol +1)/2)), and the granularity of the sub-field is 1 symbol. Then the UE may determine the time zone between symbol 5 and symbol 8 in slot n+1 as the target time zone, and cancel the uplink in the time zone between symbol 5 and symbol 8 in slot n+1 eMBB service transmission (the filling pattern in FIG. 10 is the part indicated by reference numeral 23).
再如图11所示，假设UE根据UL CI的指示确定出K3＝1个时隙，参考时间区域的总长度为1个时隙(X＝1)，UE在时隙n接收到UL CI(图11中的12)，UE将从时隙n开始经过K3之后的第一个时隙的边界确定为第一起始时刻t1，将时隙n+1确定为参考时间区域(图11中的21)。并且，假设UL CI进一步指示第二起始时刻t2为第一起始时刻t1之后的第4个符号(starting symbol为4)，目标长度T为5个符号，UL CI中用于指示t1和T的比特区域的大小为：Bit-field＝ceil(log2(Nsymbol/2*(Nsymbol+1)/2))，子区域的粒度为2个符号。则UE可以将时隙n+1中的符号4至符号9之间的时间区域确定为目标时间区域，并取消在时隙n+1中的符号4至符号9之间的时间区域上的上行eMBB业务传输(图11中填充图样为附图标记23所指的部分)。As shown in FIG. 11 , assuming that the UE determines K3=1 time slot according to the indication of the UL CI, the total length of the reference time region is 1 time slot (X=1), and the UE receives the UL CI in the time slot n ( 12) in FIG. 11, the UE determines the boundary of the first time slot after K3 from time slot n as the first starting time t1, and determines time slot n+1 as the reference time area (21 in FIG. 11 ). And, assuming that the UL CI further indicates that the second starting moment t2 is the fourth symbol (starting symbol is 4) after the first starting moment t1, and the target length T is 5 symbols, the UL CI used to indicate t1 and T The size of the bit field is: Bit-field=ceil(log2(Nsymbol /2*(Nsymbol +1)/2)), and the granularity of the sub-field is 2 symbols. Then the UE may determine the time zone between symbol 4 and symbol 9 in slot n+1 as the target time zone, and cancel the uplink in the time zone between symbol 4 and symbol 9 in slot n+1 eMBB service transmission (the filling pattern in FIG. 11 is the part indicated by reference numeral 23).
再如图12所示，假设UE根据最小取消时间(tmin＝10个符号)和TA(TA＝2个符号)确定出预设时间间隔为12个符号，参考时间区域的总长度为1个时隙(X＝1)，UE在时隙n的第1个符号接收到UL CI(图12中的12)，则UE可以确定出第一起始时刻t1为从时隙n的第1个符号开始经过12个符号之后的第一个时隙的边界，参考时间区域为时隙n+1(图12中的21)。并且，假设UL CI进一步指示第二起始时刻t2为第一起始时刻t1之后的第4个符号(startingsymbol为4)，目标长度T为5个符号，UL CI中用于指示t1和T的比特区域的大小为：Bit-field＝ceil(log2(Nsymbol/2*(Nsymbol+1)/2))，子区域的粒度为2个符号。则UE可以将时隙n+1中的符号4至符号9之间的时间区域确定为目标时间区域，并取消在时隙n+1中的符号4至符号9之间的时间区域上的上行eMBB业务传输(图12中填充图样为附图标记23所指的部分)。As shown in Fig. 12, assume that the UE determines that the preset time interval is 12 symbols according to the minimum cancellation time (tmin = 10 symbols) and TA (TA = 2 symbols), and the total length of the reference time zone is 1 time slot (X=1), the UE receives the UL CI (12 in Figure 12) at the first symbol of time slot n, then the UE can determine that the first starting time t1 is from the first symbol of time slot n The boundary of the first time slot after 12 symbols has passed, and the reference time zone is time slot n+1 (21 in FIG. 12 ). And, assuming that the UL CI further indicates that the second starting moment t2 is the fourth symbol (startingsymbol is 4) after the first starting moment t1, and the target length T is 5 symbols, the bits used to indicate t1 and T in the UL CI The size of the area is: Bit-field=ceil(log2(Nsymbol /2*(Nsymbol +1)/2)), and the granularity of the sub-area is 2 symbols. Then the UE may determine the time zone between symbol 4 and symbol 9 in slot n+1 as the target time zone, and cancel the uplink in the time zone between symbol 4 and symbol 9 in slot n+1 eMBB service transmission (the filling pattern in FIG. 12 is the part indicated by reference numeral 23).
再如图13所示，假设UE根据最小取消时间(tmin＝10个符号)和TA(TA＝2个符号)确定出预设时间间隔为12个符号，参考时间区域的总长度为Y个符号，UE在时隙n的第1个符号接收到UL CI(图13中的12)，则UE可以确定出第一起始时刻t1为从时隙n的第1个符号开始经过12个符号之后的第一个符号，参考时间区域为第一起始时刻t1开始的Y个符号(图13中的21)。并且，假设UL CI进一步指示第二起始时刻t2为第一起始时刻t1之后的第5个符号(starting symbol为4)，目标长度T为6(duration＝6)个符号，UL CI中用于指示t1和T的比特区域的大小为：Bit-field＝ceil(log2(Y/2*(Y+1)/2))，子区域的粒度为2个符号。则UE可以将第一起始时刻t1之后的第5个符号至第一起始时刻t1之后的第11个符号之间的时间区域确定为目标时间区域，并取消该目标时间区域上的上行eMBB业务传输(图13中填充图样为附图标记23所指的部分)。As shown in Figure 13, assume that the UE determines that the preset time interval is 12 symbols according to the minimum cancellation time (tmin = 10 symbols) and TA (TA = 2 symbols), and the total length of the reference time zone is Y symbol, the UE receives the UL CI (12 in Figure 13) in the first symbol of slot n, then the UE can determine that the first starting time t1 is after 12 symbols from the first symbol of slot n The first symbol of , the reference time zone is Y symbols starting from the first starting time t1 (21 in FIG. 13 ). And, assuming that the UL CI further indicates that the second start time t2 is the fifth symbol (starting symbol is 4) after the first start time t1, and the target length T is 6 (duration=6) symbols, the UL CI is used for The size of the bit field indicating t1 and T is: Bit-field=ceil(log2(Y/2*(Y+1)/2)), and the granularity of the sub-field is 2 symbols. Then the UE may determine the time zone between the 5th symbol after the first start time t1 and the 11th symbol after the first start time t1 as the target time zone, and cancel the uplink eMBB service transmission in the target time zone (The filling pattern in FIG. 13 is the part indicated by reference numeral 23).
本发明实施例提供的一种取消上行传输的方法，可以在接收到上行传输取消指令时，确定出参考时间区域的起始时刻，并根据参考时间区域的起始时刻确定出目标时间区域，进而暂停或取消在目标时间区域上的上行传输。因此，可以使终端设备明确需要取消的上行传输的具体时域资源，提高了系统的资源调度效率。A method for canceling uplink transmission provided by an embodiment of the present invention can determine the starting time of the reference time zone when receiving the uplink transmission canceling instruction, and determine the target time zone according to the starting time of the reference time zone, and then Pause or cancel upstream transmissions on the target time zone. Therefore, it is possible for the terminal device to specify the specific time-domain resource of the uplink transmission that needs to be canceled, thereby improving the resource scheduling efficiency of the system.
在本发明的又一实施例中，取消上行传输资源的方法可以包括：在接收到上行传输取消指令(UL CI)时，根据所述上行传输取消指令中指示的时延(offset)，确定取消上行传输的时隙；根据所述上行传输取消指令中指示的要取消上行传输的起始符号，以及所述取消上行传输的时隙，确定取消上行传输的目标时间区域。也即，不设定参考时间区域(或者说隐含设定参考时间区域)，UL CI中指示时延和实际要取消的时隙或符号(cancelledslot/symbol(s))。In yet another embodiment of the present invention, the method for canceling uplink transmission resources may include: when receiving an uplink transmission cancellation instruction (UL CI), determining to cancel the resource according to the delay (offset) indicated in the uplink transmission cancellation instruction A time slot for uplink transmission: determine a target time zone for canceling uplink transmission according to the start symbol for which uplink transmission is to be canceled indicated in the uplink transmission cancellation instruction and the time slot for canceling uplink transmission. That is, the reference time zone is not set (or the reference time zone is implicitly set), and the UL CI indicates the time delay and actually canceled time slots or symbols (cancelled slot/symbol(s)).
其中，根据所述上行传输取消指令中指示的时延(offset)，确定取消上行传输的时隙，包括：将从所述上行传输取消指令的接收时刻开始经过所述时延之后的第一个符号所在的时隙，确定为取消上行传输的时隙。Wherein, according to the time delay (offset) indicated in the uplink transmission cancellation instruction, determining the time slot for canceling the uplink transmission includes: starting from the receiving moment of the uplink transmission cancellation instruction and passing the first time slot after the time delay The time slot where the symbol is located is determined as the time slot for canceling uplink transmission.
具体而言，可以预先通过RRC在UE中配置一个K3时延的集合(见上文中的表1)，ULCI指示具体的K3值，UE根据UL CI的接收时刻和K3确定要取消的符号所在的时隙，然后从所指示的起始符号开始，取消该时隙上的上行传输。Specifically, a set of K3 delays can be configured in the UE through RRC in advance (see Table 1 above), ULCI indicates the specific K3 value, and the UE determines the location of the symbol to be canceled according to the receiving time of the UL CI and K3 time slot, and then, starting from the indicated start symbol, cancel the uplink transmission on that time slot.
具体如图14所示，假设UE在时隙n的符号i接收到UL CI(图14中的12)，且UL CI指示了K3的具体值，UE根据UL CI的接收时刻和K3确定出取消上行传输的时隙为时隙n+1。并且，假设UL CI进一步指示要取消上行传输的起始符号为4(starting symbol为4)，则可以将时隙n+1中的符号4至时隙n+1的最后一个符号之间的时间区域确定为目标时间区域，并取消在时隙n+1中的符号4至时隙n+1的最后一个之间的时间区域上的上行eMBB业务传输(图14中填充图样为附图标记23所指的部分)。Specifically as shown in Figure 14, assuming that the UE receives the UL CI (12 in Figure 14) at the symbol i of the time slot n, and the UL CI indicates the specific value of K3, the UE determines the cancellation according to the receiving time of the UL CI and K3 The time slot for uplink transmission is time slot n+1. And, assuming that the UL CI further indicates that the starting symbol to cancel uplink transmission is 4 (starting symbol is 4), the time between symbol 4 in slot n+1 and the last symbol of slot n+1 can be The area is determined as the target time area, and the uplink eMBB service transmission on the time area between symbol 4 in slot n+1 and the last one of slot n+1 is canceled (the filling pattern in FIG. 14 is reference numeral 23 refers to the part).
再比如，假设UL CI中用一个比特区域(Bit-field)指示相对于UL CI的接收时刻的要取消上行传输的符号(cancelled symbol(s))中的起始符号(starting symbol)，且网络设备预先通过RRC配置的比特区域的大小为：Bit-field size＝ceil(log2(max_total_symbol_num/Nbundle_size))，其中，Nbundle_size表示符号组合的大小(symbol bundle size)，由RRC配置UL CI能指示的最远的起始符号，该配置也决定了比特区域的大小；max_total_symbol_num，表示RRC隐式配置或默认的参考时间区域的总符号数。UE接收到UL CI之后，根据比特区域中的指示确定要取消上行传输的起始符号所在的时隙，然后从所示指示的起始符号开始，取消该时隙上的上行传输。For another example, assume that a bit field (Bit-field) is used in the UL CI to indicate the starting symbol (cancelled symbol(s)) in the symbol (cancelled symbol(s)) relative to the receiving moment of the UL CI, and the network The size of the bit area configured by the device in advance through RRC is: Bit-field size=ceil(log2(max_total_symbol_num/Nbundle_size )), where Nbundle_size represents the size of the symbol bundle (symbol bundle size), which can be indicated by the UL CI configured by RRC This configuration also determines the size of the bit area; max_total_symbol_num indicates the total number of symbols in the RRC implicit configuration or default reference time area. After receiving the UL CI, the UE determines the time slot where the start symbol of the uplink transmission is to be canceled according to the indication in the bit area, and then cancels the uplink transmission on the time slot starting from the indicated start symbol.
又比如，假设UL CI中用一个比特区域(Bit-field)指示相对于UL CI的接收时刻的要取消上行传输的符号(cancelled symbol(s))中的起始符号(starting symbol)和目标长度(duration)，也即UL CI指示SLIV，且网络设备预先通过RRC配置的比特区域的大小为：Bit-field size＝ceil(log2(max_total_symbol_num/Nbundle_size)*(max_total_symbol_num/Nbundle_size)+1)/2)，其中，Nbundle_size表示符号组合的大小(symbol bundlesize)，由RRC配置UL CI能指示的最远的起始符号，该配置也决定了比特区域的大小。UE接收到UL CI之后，根据UL CI的比特区域中所指示的SLIV确定要取消上行传输的起始符号和目标长度，然后从所示指示的起始符号开始，取消在目标长度的时域资源上的上行传输。For another example, assume that a bit field (Bit-field) is used in the UL CI to indicate the starting symbol (cancelled symbol(s)) and the target length of the symbol (cancelled symbol(s)) to be canceled relative to the receiving moment of the UL CI (duration), that is, the UL CI indicates SLIV, and the size of the bit field configured by the network device in advance through RRC is: Bit-field size=ceil(log2(max_total_symbol_num/Nbundle_size )*(max_total_symbol_num/Nbundle_size )+1)/ 2), wherein, Nbundle_size represents the size of the symbol bundle (symbol bundle size), and the farthest starting symbol that can be indicated by the UL CI is configured by RRC, and this configuration also determines the size of the bit area. After receiving the UL CI, the UE determines the start symbol and target length of the uplink transmission to be canceled according to the SLIV indicated in the bit area of the UL CI, and then cancels the time domain resources at the target length starting from the indicated start symbol uplink transmission.
下面对上文中述及的子区域(或者符号组合)进行说明。The subregions (or combinations of symbols) mentioned above will be described below.
可选地，本发明任一实施例提供的一种取消上相传输的方法还可以包括：基于用于划分所述参考时间区域的高层信令(例如RRC)，将所述参考时间区域划分为预设长度的多个子区域，或者将一个时隙划分为预设长度的多个子区域，以减小UL CI中的比特区域的大小，从而节省传输资源。Optionally, a method for canceling upper-phase transmission provided by any embodiment of the present invention may further include: dividing the reference time region into Multiple sub-regions with a preset length, or divide a time slot into multiple sub-regions with a preset length, so as to reduce the size of the bit region in the UL CI, thereby saving transmission resources.
其中，所述预设长度大于或等于一个时间符号；所述目标起始时刻信息用于指示取消上行传输的时域资源中包括的子区域中的起始子区域，所述目标长度信息用于指示取消上行传输的时域资源中包括的子区域的数量。Wherein, the preset length is greater than or equal to one time symbol; the target start time information is used to indicate the start sub-region in the sub-regions included in the time-domain resource for canceling uplink transmission, and the target length information is used to Indicates the number of sub-regions included in the time-domain resource for which uplink transmission is canceled.
举例来说，假设一个时隙有14个符号，当子区域的大小等于1个符号时，UL CI需要4个比特(能指示0～15)才能实现对时隙中所有符号的指示；当子区域的大小等于2个符号时(2个符号的组合)，该时隙包括7个子区域，UL CI需要3个比特(能指示0～7)就能实现对该时隙中所有子区域的指示，因此，对时隙中或参考时间区域中的符号进行组合，可以减少UL CI中的比特区域的大小，能够节省UL CI占用的传输资源。For example, assuming that there are 14 symbols in a time slot, when the size of the sub-region is equal to 1 symbol, UL CI needs 4 bits (can indicate 0-15) to realize the indication of all symbols in the time slot; When the size of the area is equal to 2 symbols (combination of 2 symbols), the time slot includes 7 sub-areas, and UL CI needs 3 bits (can indicate 0~7) to realize the indication of all sub-areas in the time slot , therefore, combining the symbols in the time slot or in the reference time region can reduce the size of the bit region in the UL CI and save the transmission resources occupied by the UL CI.
在具体实现时，子区域的大小(或符号组合的大小)可以由网络设备通过RRC进行配置。During specific implementation, the size of the sub-area (or the size of the symbol combination) can be configured by the network device through RRC.
例如，如图15所示，假设UE在时隙n接收到UL CI(图15中的12)，参考时间区域的总长度为2个时隙，且UL CI指示了K3＝1个时隙，UE将从时隙n开始经过K3之后的第一个时隙的边界确定为第一起始时刻t1，将时隙n+1和时隙n+2确定为参考时间区域，以及，UL CI指示的子区域的粒度为2个符号。并且，参考频域资源(Reference frequency region)为ULBWP，参考频域资源分为4个频带子集，UL CI用2比特指示具体要取消的频带子集，作为目标频域资源。以及，UL CI进一步指示要取消上行传输的起始符号为5(starting symbol为5)，UL指示要取消上行传输的目标频域资源为第一个频带子集；则UE确定可以取消的频域资源为，在时隙n+1的第5个符号至时隙n+2的第14个符号上，与目标频域资源重叠的频域资源(图15中填充图样为附图标记23所指的部分)。在图15中t表示时间，f表示频率。For example, as shown in Figure 15, assuming that the UE receives the UL CI (12 in Figure 15) at time slot n, the total length of the reference time region is 2 time slots, and the UL CI indicates K3=1 time slot, The UE determines the boundary of the first time slot after K3 from time slot n as the first start time t1, determines time slot n+1 and time slot n+2 as the reference time area, and the UL CI indicates The granularity of subregions is 2 symbols. In addition, the reference frequency domain resource (Reference frequency region) is ULBWP, and the reference frequency domain resource is divided into 4 frequency band subsets, and the UL CI uses 2 bits to indicate the specific frequency band subset to be canceled as the target frequency domain resource. And, the UL CI further indicates that the starting symbol to cancel the uplink transmission is 5 (starting symbol is 5), and the UL indicates that the target frequency domain resource to cancel the uplink transmission is the first frequency band subset; then the UE determines the frequency domain that can be canceled The resource is, on the 5th symbol of time slot n+1 to the 14th symbol of time slot n+2, a frequency domain resource overlapping with the target frequency domain resource (the filling pattern in FIG. 15 is indicated by reference numeral 23 part). In FIG. 15 t represents time and f represents frequency.
