Description

重复传输数据信道的方法和设备 技术领域
本申请实施例涉及通信领域，具体涉及一种重复传输数据信道的方法和设备。
背景技术
在新无线(New Radio，NR)系统中，网络设备可以配置终端设备采用多时隙重复传输，提升传输覆盖。在数据信道进行编码映射时，首先需要确定数据信道对应的传输块大小(Transport Block Size，TBS)，在相关技术中，确定数据信道对应的TBS只考虑一个时隙中的正交频分复用(Orthogonal frequency-division multiplexing，OFDM)符号分配，当多时隙重复传输需要适应灵活的时隙配比时，基于此方式确定TBS可能会导致确定的TBS过大或者过小，并且在覆盖受限的情况下，为了获得特定比特速率，需要分配较多的物理资源块(physical resource block，PRB)，降低了资源利用率。
发明内容
本申请提供了一种重复传输数据信道的方法和设备，有利于提升资源利用率。
第一方面，提供了一种重复传输数据信道的方法，包括：根据第一重复时隙因子和/或重复传输所述数据信道的时隙中的时域符号数，确定所述数据信道对应的传输块大小；根据所述数据信道对应的传输块大小对所述数据信道进行编码，得到编码后的信息比特；将所述编码后的信息比特映射到多个时隙上。
第二方面，提供了一种重复传输数据信道的设备，用于执行上述第一方面或其各实现方式中的方法。具体地，该设备包括用于执行上述第一方面或其各实现方式中的方法的功能模块。
第三方面，提供了一种重复传输数据信道的设备，包括处理器和存储器。该存储器用于存储计算机程序，该处理器用于调用并运行该存储器中存储的计算机程序，执行上述第一方面或其各实现方式中的方法。
第四方面，提供了一种芯片，用于实现上述第一方面其各实现方式中的方法。
具体地，该芯片包括：处理器，用于从存储器中调用并运行计算机程序，使得安装有该装置的设备执行如上述第一方面或其各实现方式中的方法。
第五方面，提供了一种计算机可读存储介质，用于存储计算机程序，该计算机程序使得计算机执行上述第一方面或其各实现方式中的方法。
第六方面，提供了一种计算机程序产品，包括计算机程序指令，所述计算机程序指令使得计算机执行上述第一方面或其各实现方式中的方法。
第七方面，提供了一种计算机程序，当其在计算机上运行时，使得计算机执行上述第一方面或其各实现方式中的方法。
通过上述技术方案，在配置第二时隙重复因子的情况下，根据第一重复时隙因子和/ 或实际用于重复传输数据信道的时隙中的时域符号数确定TBS，相当于考虑多个时隙中的时域符号分配计算TBS，能够提升计算得到的TBS的大小，进一步地，为了获得相同的比特速率，只需分配较少数量的PRB，从而能够提升资源利用率。

在NR系统，可以通过上下行的聚合因子(Aggregation factor)来进行多时隙(slot)的PUSCH和PDSCH传输。终端设备通过多slot重复传输，可以提高单次传输的覆盖。
由于Aggregation factor是半静态配置的，重复进行一个PUSCH/PDSCH传输时总是在每个slot里面采用相同的解调参考信号(Demodulation Reference Signal，DMRS)时域结构。
NR系统支持灵活的时隙配比，一个时隙可以有部分上行时域符号和部分时域符号，物理上行控制信道(Physical Uplink Control Channel，PUCCH)和物理上行共享信道(Physical Uplink Shared Channel，PUSCH)只在上行时域符号中传输，物理下行控制信道(Physical Downlink Control Channel，PDCCH)和物理下行共享信道(Physical Downlink Shared Channel，PDSCH)只在上行时域符号中传输。以PUSCH的传输为例，要实现多时隙重复传输，传输PUSCH的时隙中的可用符号的起始位置和数量都要满足PUSCH的资源配置，否则，终端设备忽略在该时隙上的重复传输。
图2示出了一种多时隙重复传输的示意图。如图2所示，由于时隙1和时隙2中的符号配置基本为下行时域符号，上行时域符号的数量不满足传输需求，因此，终端设备忽略在该时隙1和时隙2上的传输，而只在时隙0和时隙3上进行重复传输，因此，在配置终端设备进行四次重复传输的情况下，终端设备实际上只进行了两次重复传输。
在进行多时隙重复传输时，需要首先确定数据信道对应的传输块大小(Transport Block Size，TBS)，在相关技术中，确定TBS只考虑一个时隙中的OFDM符号分配，这种设计要求每个slot中的OFDM符号完全一样。
当多时隙重复传输需要适应灵活的时隙配比时，基于此方式确定TBS可能会导致确定的TBS过大或者过小。并且在覆盖受限的情况下，为了获得特定比特速率，需要分配较多的物理资源块(physical resource block，PRB)，降低了资源利用率。因此，如何确定多时隙重复传输中的TBS大小以提升资源利用率是一项急需解决的问题。
为便于理解本申请实施例的技术方案，以下通过具体实施例详述本申请的技术方案。以上相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。本申请实施例包括以下内容中的至少部分内容。
图3是根据本申请实施例的重复传输数据信道的方法300的示意性流程图，该方法300可以由图1所示的通信系统中的终端设备或网络设备执行，以下，以终端设备为执行主体描述本申请实施例，网络设备的行为类似，为了简洁，这里不再赘述。
如图3所示，该方法300包括如下内容：
S310，根据第一重复时隙因子和/或重复传输所述数据信道的时隙中的时域符号数，确定所述数据信道对应的传输块大小；
S320，根据所述数据信道对应的传输块大小对所述数据信道进行编码，得到编码后的信息比特；
S330，将所述编码后的信息比特映射到多个时隙上。
应理解，本申请实施例可以适用于确定数据信道的TBS，或者也可以适用于确定其他信道的TBS，例如控制信道等，本申请对此不作限定。
可选地，在一些实施例中，所述数据信道可以为上行数据信道，例如物理上行共享信道(Physical Uplink Shared channel，PUSCH)，或者也可以为下行数据信道，例如物理下行共享信道(Physical Downlink Shared Channel，PDSCH)。
可选地，在一些实施例中，时域符号可以指OFDM符号，时域符号数可以指OFDM符号数。
在本申请一些实施例中，终端设备可以在被配置第二重复时隙因子的情况下，根据第一重复时隙因子和/或重复传输所述数据信道的时隙中的时域符号数确定所述数据信道的TBS，所述第二重复时隙因子用于指示重复传输数据信道的时隙数。
可选地，所述第二重复时隙因子可以是网络设备配置的。例如，网络设备可以通过无线资源控制(Radio Resource Control，RRC)信令配置该第二重复时隙因子，或者也可以通过其他信令配置该第二重复时隙因子，本申请对此不作限定。

例如，所述第一重复时隙因子为所述第二重复时隙因子乘以第一系数，其中，所述第一系数为小于等于1的正数。
可选地，在一些实施例中，所述第一重复时隙因子是网络设备配置的。
例如，网络设备可以通过RRC信令，下行控制信息DCI等下行消息或信令配置该第一重复时隙因子。
可选地，在一些实施例中，所述第一重复时隙因子根据实际重复传输所述数据信道的时隙数确定。例如，在图2示例中，第二重复时隙因子为4，实现用于多时隙传输的时隙数为2，则该第一重复时隙因子可以为2。
可选地，在一些实施例中，所述S310可以包括：
根据所述第一重复时隙因子和调度参数，确定所述数据信道对应的传输块大小。
在一些实施例中，所述调度参数包括以下中的至少一项：

以下，结合具体实施例，说明根据所述第一重复时隙因子和所述调度参数，确定信息比特的中间数的实现方式。
实施例一
所述终端设备可以根据如下公式(1)，确定所述信息比特的中间数N info：
N info＝N RE·R·Q m·υ·X             公式(1)
其中，所述N RE表示目标RE数，所述R表示码率，所述Q m表示调制阶数，所述υ表示传输层数，所述X表示所述第一重复时隙因子。
在该实施例一中，所述目标RE数N RE可以根据如下公式(2)确定：

其中，所述N表示第一参考RE数阈值，N' RE表示一个时隙中的参考可用RE数，所述n PRB表示网络设备分配的RB个数，min表示取最小值。
可选地，所述第一参考RE数阈值可以为156，或者也可以为其他数值，本申请对此不作限定。
在一些实施例中，一个时隙中的参考可用RE数N' RE可以采用如下公式(3)确定：
Figure PCTCN2020141059-appb-000001
其中，
Figure PCTCN2020141059-appb-000002
表示每个RB上的子载波个数，
Figure PCTCN2020141059-appb-000003
表示每个时隙中的时域符号个数，
Figure PCTCN2020141059-appb-000004
表示每个RB中解调参考信号DMRS所占RE个数，
Figure PCTCN2020141059-appb-000005
表示开销RE数。
可选地，在一些实施例中，
Figure PCTCN2020141059-appb-000006
可以在DCI所承载的调度信息中获取。
可选地，在一些实施例中，
Figure PCTCN2020141059-appb-000007
可以是网络设备配置的，或者固定值。
可选地，在一些实施例中，X为大于1的正整数，即第一重复时隙因子为正整数。
因此，在该实施例一中，根据公式(1)计算数据信道对应的TBS，相当于考虑多个时隙中的OFDM符号分配计算TBS，能够提升计算得到的TBS的大小，进一步地，为 了获得相同的比特速率，只需分配较少数量的PRB，从而能够提升资源利用率。
实施例二
所述根据所述第一重复时隙因子和调度参数，确定所述信息比特的中间数，包括：
根据所述第一重复时隙因子X，确定目标RE数N RE；
根据所述目标RE数和调度参数，确定所述信息比特的中间数。
在一些实施例中，所述根据所述第一重复时隙因子，确定目标RE数N RE，包括：
根据所述第一重复时隙因子X和一个时隙中的参考可用RE数N' RE，确定所述目标RE数N RE。
作为一个实现方式，所述终端设备可以根据公式(4)确定所述目标RE数N RE：
N RE＝X·min(N,N' RE)·n PRB        公式(4)
其中，所述X表示所述第一重复时隙因子，所述N表示第一参考RE数阈值，所述n PRB表示网络设备分配的资源块RB个数，N' RE表示一个时隙内的参考可用RE数。
可选地，所述第一参考RE数阈值可以为156，或者也可以为其他数值，本申请对此不作限定。
可选地，在一些实施例中，终端设备可以根据上述公式(3)，确定所述一个时隙内的参考可用RE数N' RE。
进一步地，所述终端设备可以根据公式(5)确定所述信息比特的中间数N info：
N info＝N RE·R·Q m·υ        公式(5)
其中，所述N RE表示根据公式(4)确定的目标RE数，所述R表示码率，所述Q m表示调制阶数，所述υ表示传输层数。
因此，在该实现方式中，根据公式(4)计算目标RE数N RE，即根据第一重复时隙因子计算目标RE数，相当于考虑多个时隙中的OFDM符号分配计算TBS，能够提升计算得到的TBS的大小，进一步地，为了获得相同的比特速率，只需分配较少数量的PRB，从而能够提升资源利用率。
在另一些实施例中，所述根据所述第一重复时隙因子，确定目标RE数N RE，包括：
所述终端设备可以根据所述第一重复时隙因子和重复传输所述数据信道的时隙中的时域符号数，确定重复传输所述数据信道的时隙上的参考可用RE数；
根据重复传输所述数据信道的时隙上的参考可用RE数，确定所述目标RE数。
在本申请一些实施例中，重复传输所述数据信道的时隙中的时域符号数可以指实际传输数据信道的时隙中的可用时域符号数，或者，实际传输数据信道的时隙中的实际用于传输数据信道的时域符号数。
在本申请实施例中，考虑实际用于重复传输数据信道的时隙中的时域符号数确定TBS，能够根据灵活时隙结构动态确定用于传输数据信道的时域符号数，有利于克服相关技术中根据单个时隙中的时域符号数确定TBS，导致计算的TBS过大或过小的问题。并且由于考虑了多个时隙中的时域符号数确定TBS，能够提升计算得到的TBS的大小，进一步地，为了获得相同的比特速率，只需分配较少数量的PRB，从而能够提升资源利 用率。
并且，考虑实际传输数据信道的时隙中的时域符号数确定TBS，能够更准确的应用于灵活时隙结构下的数据信道的自适应重复传输，更好地解决了数据信道的覆盖不足问题。
作为一个实现方式，终端设备根据如下公式(6)确定重复传输所述数据信道的时隙上的参考可用RE数N″ RE：
Figure PCTCN2020141059-appb-000008
其中，所述X表示所述第一重复时隙因子，
Figure PCTCN2020141059-appb-000009
表示每个RB上的子载波个数，
Figure PCTCN2020141059-appb-000010
表示重复传输所述数据信道的第i个时隙中的时域符号数，
Figure PCTCN2020141059-appb-000011
表示在重复传输所述数据信道的第i个时隙中的每个RB中DMRS所占RE个数，
Figure PCTCN2020141059-appb-000012
表示开销RE数。
在该实现方式中，该N″ RE与前述实施例的N' RE的确定方式不同，该N″ RE考虑了实际传输数据信道的时隙上的时域符号数以及DMRS数，考虑实际重复传输数据信道的时隙的DMRS和数据(payload)的OFDM符号的折算问题，采用此方式计算的参考可用RE数更为准确。
因此，在本申请实施例中，计算传输块大小时，根据帧结构的时隙配置和第二重复时隙因子确定实际重复传输数据信道所用到的RE资源数量，有利于保证合理的资源分配和码率等编码参数。
进一步地，在一些实施例中，根据公式(7)确定所述目标RE数N RE：
N RE＝min(N',N″ RE)·n PRB      公式(7)
其中，所述N'表示第二参考RE数阈值，n PRB表示网络设备分配的RB个数，N″ RE表示重复传输所述数据信道的时隙上的参考可用RE数，该N″ RE为根据公式(6)确定。
可选地，在一些实施例中，所述第二参考RE数阈值可以为156，或者156*X。
也就是说，可以根据如下公式(8)或公式(9)确定所述目标RE数N RE。
N RE＝min(156·X,N' RE)·n PRB        公式(8)
N RE＝min(156,N' RE)·n PRB        公式(9)
进一步地，所述终端设备可以将公式(7)代入公式(5)得到所述信息比特的中间数N info。
基于上述实施例，可以确定所述信息比特的中间数N info。
进一步地，在一些实施例中，所述终端设备可以对所述信息比特的中间数进行量化和取整处理，确定所述数据信道对应的传输块大小。
例如，将传输块大小列表中不小于所述信息比特的中间数，并且与所述信息比特的中间数的差值最小的传输块大小确定为所述数据信道对应的传输块大小。
作为一个示例，传输块大小TBS列表如表1所示，若根据前述实施例确定的所述信息比特的中间数为101.9，则查表找到一个不小于101.9并且与该101.9最接近的TBS，即104作为数据信道的TBS。
