为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
在目前的多时隙传输机制中，根据一个时隙中的数据信道(例如，PDSCH或PUSCH)的资源大小计算传输块大小，并在多个时隙中的数据信道的资源位置重复传输该大小的传输块。若在该多个时隙中的一个或多个时隙中的该数据信道的资源包含其他高优先级用途的资源时，该一个或多个时隙中的重复传输将被取消。这样计算传输块大小、以及取消传输的方式，将导致无法达到预期的传输可靠性。
本申请提出当传输块在多个时域符号组中重复传输时，由于通信双方一般对通信资源的优先级能够预先达成共识，因此，可以确定在该多个时域符号组中实际可以用于传输该传输块的数据信道的资源大小。根据实际能够传输该传输块的数据信道的资源大小计算传输块的大小，在一个时域符号组中包含高优先级的资源的情况下，在除高优先级以外的能够传输该传输块的数据信道资源(即作为实际传输传输块的数据信道资源)上传输该传输块。这使得传输块大小与数据信道资源大小的比例保持在一定 值，能够避免现有技术中因取消重复传输中的某一次或多次传输而造成的可靠性下降的情况。能够达到重复传输的预期效果，增加覆盖范围、提高传输块传输的可靠性。
下面结合附图详细说明本申请实施例提供的传输块大小的确定方法。
需要说明的是，本申请提供的传输块大小的确定方法可以由终端设备执行也可以由网络设备执行。可以是网络设备与终端设备进行通信时，网络设备和终端设备通过该方法确定传输块的大小，也可以是两个终端设备进行通信时，通过该方法确定传输块的大小。下面以终端设备确定传输块的大小为例进行说明，但本申请不限于此。
图2是本申请实施例提供的传输块大小的确定方法的一个示意性流程图。
S210，终端设备确定第一传输块在J个时域符号组中重复传输，该J个时域符号组中的每个时域符号组包括L个时域符号。
一种实施方式中，网络设备可以为终端设备配置第一传输块的重复次数J，在该配置重复次数J生效后，网络设备通过指示信息通知终端设备调度或授权的用于传输第一传输块的第一数据信道，终端设备可以根据该配置的或指示的重复次数J确定该第一传输块重复传输J次。
例如，网络设备可以通过无线资源控制(radio resource control，RRC)消息为终端设备配置调度第一数据信道时该第一数据信道的重复次数。该第一数据信道可以是上行数据信道(例如，PUSCH)或下行数据信道(例如PUSCH)。例如，该第一数据信道为PUSCH，该RRC消息中包括PUSCH聚合因子信元，该PUSCH聚合因子信元用于配置网络设备授权终端设备用于发送第一传输块的PUSCH的重复次数J。该PUSCH聚合因子信元可以写作PUSCH-AggregationFactor，但本申请不限于此。当终端设备接收到该RRC消息中的PUSCH-AggregationFactor信元且该信元生效后，终端设备接收到来自网络设备的上行授权(UL-grant)DCI，该DCI用于指示网络设备授权的、用于终端设备发送上行传输块(即第一传输块的一个示例)的PUSCH的时频资源。终端设备可以根据RRC消息确定该上行传输块重复传输J次，以及可以根据该DCI指示的PUSCH的时频资源，确定每个用于承载重复传输的该上行数据块的PUSCH的时频资源。
一个示例中，该上行授权DCI指示一个时间单元中的PUSCH的时频资源，以及该上行授权DCI指示传输该传输块的第一个时间单元，终端设备根据重复次数J，确定该上行传输块在以该第一个时间单元为起始的连续的J个时间单元中的该PUSCH的时频资源上重复传输。也就是说，该J个时域符号组为该J个时间单元中的时域符号组(即DCI指示的PUSCH的时频资源包含的时域符号的个数)，该J个时域符号组中的一个时域符号组为一个时间单元中的时域符号组。
例如，每个时间单元包括14个符号，网络设备可以通过RRC消息配置重复次数J为3。在该RRC消息生效后，终端设备接收到来自网络设备的DCI，该DCI指示授权的PUSCH的时频资源在时域上为一个时间单元中的符号3至符号8共6个符号(即L为6)，频域上为多个资源块，且该DCI还指示传输该第一传输块的起始时间单元为时间单元n。如图3所示，终端设备接收到该DCI后，可以确定在连续的3个时间单元(即时间单元n、时间单元n+1和时间单元n+2)中的每个时间单元中的符号3至符号8中传输第一传输块。也就是说，终端设备确定第一传输块在3个时域符号组中重复传输3次，该3个时域符号组分别为时间单元n、时间单元n+1和时间单元n+2中的符号3至符号8，即该3个时域符号组中的每个时域符号组包括6个时域符号。但本申请不限于此。
可选地，该时间单元可以是时隙、子帧或帧。
另一个示例中，该上行授权DCI指示授权的一个PUSCH的时频资源，一个PUSCH的时频资源包括时域连续的L个时域符号。终端设备确定在连续的J个时域符号组中 重复传输该第一传输块。
例如，网络设备可以通过RRC消息配置重复次数J为4。在该RRC消息生效后，终端设备接收到来自网络设备的DCI，该DCI指示授权的第一个PUSCH的时频资源在时域上符号3开始的连续3个符号。终端设备可以确定在连续的4个时域符号组中重复传输该第一传输块，每个时域符号组包括3个时域符号，且该连续的4个时域符号组的第一个时域符号组(即符号组0)为符号3开始的连续3个符号组。则终端设备可以确定该连续的4个符号组中的符号组1、符号组2和符号组3中包含的时域符号分别为符号6至符号8、符号9至符号11和符号12至符号14，但本申请不限于此。
以上以上行传输块重复传输为例进行了说明，该第一传输块还可以是下行传输块。例如网络设备可以通过RRC消息为终端设备配置下行数据信道(例如PDSCH)的重复传输次数，如该RRC消息中可以包括PDSCH聚合因子信元，用于配置网络设备调度的、用于承载网络设备向终端设备发送的下行传输块(即第一传输块的另一个示例)的PDSCH的重复次数J。该PDSCH聚合因子信元可以写作PDSCH-AggregationFactor，但本申请不限于此。终端设备接收到该RRC信令后，根据PDSCH-AggregationFactor信元确定网络设备向该终端设备发送的下行传输块将被重复发送J次。在该PDSCH-AggregationFactor信元生效后，终端设备接收到来自网络设备的、调度用于承载下行传输块的PDSCH的DCI，该DCI指示调度的PDSCH的时频资源包括L个时域符号，终端设备可以确定J个时域符号组用于网络设备重复发送该下行传输块，每个时域符号组包括L个时域符号，接收该J个时域符号组，确定该下行传输块的大小，解调解码该J个时域符号组得到该下行传输块，但本申请不限于此。具体确定该J个时域符号组的方式与上述对上行传输块重复传输的方式类似，具体实施中可以参考上述描述，为了简要，在此不再赘述。
可选地，网络设备还可以通过DCI指示PDSCH或PUSCH的重复次数，或者传输块的重复传输次数。
例如，网络设备可以在授权PUSCH的DCI中指示该PUSCH的重复次数，或者在调度PDSCH的DCI中指示该PDSCH的重复次数等，但本申请不限于此。
终端设备在S210中确定第一传输块在J个时域符号组中重复传输后，由于该J个时域符号组中可能包括用于传输更高优先级信号的资源，或者包括传输方向与该第一数据信道的传输方向不同的资源，使得该J个时域符号组中实际传输第一传输块的资源可能小于该J个时域符号组包含的资源。
例如图3示例中，终端设备在S210中确定用于重复传输第一传输块的3个时域符号组。由于网络设备和终端设备一般对通信资源的优先级能够预先达成共识，例如资源的上行和下行配置等，若第一传输块为上行传输块，而该3个时域符号组中的第2个时域符号组(即时间单元n+1)中包括2个下行符号，例如符号7、符号8为下行符号，那么该2个下行符号不能用于网络设备传输上行传输块，也就是说，该2个下行符号不能作为第一数据信道(即上行数据信道)的资源。因此，终端设备实际能够传输该第一传输块的资源将小于该J个时域符号组包含的资源。
再例如图4示例中，终端设备在210中确定用于重复传输第一传输块的4个时域符号组。第一传输块为上行传输块，若时域符号组1中的符号7、符号8，以及符号组2中的符号9为下行符号，则该符号7、8、9不能用于传输上行传输块，因此终端设备实际能够传输第一传输块的资源将小于J个时域符号组包含的资源。
为了保证传输块重复传输的可靠性，终端设备可以在S220中根据该J个时域符号组中实际包含第一数据信道的资源的个数，确定第一传输块的大小。

例如，网络设备通过RRC消息预先配置网络设备向终端设备发送的用于承载下行传输块的PDSCH的重复次数为3次(即J＝3)。即第一传输块为下行传输块，第一数据信道为PDSCH。其中，可以规定在配置重复次数J的情况下，J个时域符号组为连续的J个时间单元中的时域符号组。在该RRC消息生效后，网络设备向终端设备发送一个第一DCI，该第一DCI用于指示一个时间单元中的PDSCH的时频资源。例如，该第一DCI包括第一指示信息，该第一指示信息用于指示该PDSCH的时频资源在时域上包括起始符号为符号3的连续6个时域符号，即L＝6。以及，该第一DCI还指示该PDSCH的起始时间单元为时间单元n。终端设备可以根据RRC消息确定该PDSCH的重复次数为3次，例如在以时间单元n为起始时间单元的连续的3个时间单元的符号3至符号8的6个时域符号上发送该第一传输块。例如图5所示，根据DCI的指示以及重复次数可以确定该3个时域符号组分别为时间单元n、时间单元n+1和时间单元n+2中的符号3至符号8的6个时域符号。
然而，在时间单元n+1中符号6至符号14为上行时域符号，其中，符号6、7、8不能用于传输该下行传输块，也就是说，该符号6、7、8不能作为PDSCH的时域资源。因此，终端设备确定在该时间单元n+1中包含PDSCH的时域符号的个数为符号3至符号5共3个符号。也就是说，该3个时域符号组中的第二个时域符号组(即时域符号组1)包含PDSCH的时域符号个数为3个。该3个时域符号组中的第一个时域符号组(即时域符号组0)和第三个时域符号组(即时域符号组2)包含PDSCH的时域符号个数均为6个。因此，该3个时域符号组中每个时域符号组中包含PDSCH的时域符号的个数的均值为

Figure PCTCN2020136213-appb-000041
码率R、调制结束Q和传输层数v，确定所述第一传输块的中间量N info，其中，该N info满足：
N info＝N RE·R·Q·v。
4、终端设备根据该中间量N info，确定第一传输块的大小。
终端设备可以对该中间量N info进行量化和/或取整后，得到该第一传输块的大小。
该步骤与前一实施方式中根据该中间量N info，确定第一传输块的大小的实施方式相同，可以参考前一实施方式中的介绍，为了简要，在此不再赘述。
终端设备确定第一传输块的大小后，若第一传输块为下行传输块，第一数据信道为下行数据信道，终端设备对该J个时域符号组中实际包含第一数据信道的资源上的第一数据信道进行解调、解码等处理后，得到第一传输块。或者，若第一传输块为上行传输块，第一数据信道为上行数据信道，终端设备确定该J个时域符号组中实际包含第一数据信道的资源，并对第一传输块进行编码、调制等处理后，承载该J个时域符号组中中第一数据信道的资源上发送给网络设备。
例如图5示例中，终端设备确定3个时域符号组中实际包含第一数据信道的资源为时间单元n、时间单元n+2中的符号3至符号8，以及时间单元n+1中的符号3至符号5。也就是说，第一传输块在时间单元n中的符号3至符号8中的第一数据信道的资源上传输了一次，以及在时间单元n+1中的符号3至符号5中的第一数据信道的资源上传输了一次、时间单元n+2中的符号3至符号8中的第一数据信道的资源上传输了一次，共传输了3次。终端设备接收到的包含第一数据信道的资源后，进行解调、解码等处理后得到第一传输块，但申请不限于此。
根据上述方案，根据网络设备分配的资源中实际能够传输该传输块的数据信道的资源大小计算传输块的大小，在一个时域符号组中包含高优先级的资源的情况下，在除高优先级以外的能够传输该传输块的数据信道资源(即作为实际传输传输块的数据信道资源)上传输该传输块。这使得传输块大小与数据信道资源大小的比例保持在一定值，能够避免现有技术中因取消重复传输中的某一次或多次传输而造成的可靠性下降的情况。能够达到重复传输的预期效果，增加覆盖范围、提高传输块传输的可靠性。可选地，可以根据多个符号组中每个符号组包含的实际用于传输该传输块的符号资源的均值，或者，每个符号组中每个资源块中包含的实际用于传输该传输块的资源元素 的均值，计算实际传输传输块的数据信道资源，能够减小传输块大小的复杂度，提高工作效率。
