具体实施方式
以下将描述本申请实施例，本申请实施例并且不限制权利要求书的保护范围和适用性。本领域技术人员可以在不脱离本申请实施例范围的情况下对本申请涉及的元件的功能和部署进行适应性更改，或酌情省略、替代或添加各种过程或组件。
首先，对本申请实施例涉及的一些概念进行阐述。
1、基于码本的上行传输模式
终端设备支持两种上行传输模式，不同的上行传输模式，所对应的上行传输方法不同。该两种上行传输模式分别是基于码本的上行传输模式(codebook based UL transmission scheme，CB)和基于非码本的上行传输模式(non-codebook based UL transmission scheme，NCB)，简称为CB模式和NCB模式。
其中，网络设备可通过RRC信令配置终端设备的上行传输模式。例如，当终端设备收到RRC信令中上行链路传输配置(ulTxConfig)＝‘码本(Codebook)’，即表示终端设备的上行传输模式被配置为基于码本的上行传输模式；当终端设备收到RRC信令中(ulTxConfig)＝‘非码本(NonCodebook)’，即表示终端设备的上行传输模式被配置为基于非码本的上行传输模式。
以下结合图1、表1和表2对CB模式下的上行传输方法进行阐述。请参阅图1，图1是一种CB模式的上行传输方法的示意图。如图1所示，该上行传输方法可包括以下步骤(1)至步骤(3)：
(1)终端设备发送探测参考信号(sounding reference signal,SRS)，如图1所示的SRS1和SRS2；
其中，与高层参数“codeBook”相关的SRS资源集合有多个SRS资源(resource)，则终端设备可根据该SRS资源集合发送多个SRS；若该SRS资源集合中仅有一个SRS资源，则终端设备可发送一个SRS。
(2)网络设备根据SRS，测量获得上行信道状态；根据上行信道状态选择合适的 PUSCH的预编码矩阵和秩(rank)数；网络设备根据选择的预编码矩阵和rank数，向终端设备发送下行控制信息(downlink control information,DCI)，该DCI中携带以下参数：探测参考信号资源指示(SRS resource indicator，SRI)域和传输预编码矩阵指示(Transmission precoding matrix indicator，TPMI)域；
SRI域用于指示一个SRS resource。SRI域所指示的该SRS resource是终端设备发送SRS所使用的N SRS个SRS resource中的其中一个。相应的，该SRI所占的比特数可等于
Figure PCTCN2021101087-appb-000013
例如，如图1所示，终端设备使用2个SRS resource分别发送SRS1和SRS2，则该SRI所占的比特数可等于1，即1比特，以向终端设备指示该2个SRS resource中的其中一个。终端设备根据SRI所指示的SRS resource的端口数，发送PUSCH。也就是说，终端设备传输PUSCH的端口数等于该SRI所指示的SRS resource的端口数。可选的，该SRI用于指示N SRS个SRS resource中其中一个SRSresource的索引index。
可选的，上述与高层参数“codeBook”相关的SRS资源集合中仅有一个SRS资源，则DCI中可不包括该SRI信息，终端设备可直接利用该SRS资源集合中该SRS资源的端口数作为传输PUSCH的端口数。
TPMI域用于指示PUSCH的预编码矩阵。其中，终端设备确定TPMI域对应的TPMI所指示的预编码矩阵时，还需根据上述所述的SRI和该TPMI域对应的传输秩指示(Transmission rank indicator，TRI)确定一个TPMI表，如表2所示，从该TPMI表中，读取TPMI所指示的预编码矩阵。也就是说，PUSCH的预编码矩阵是从上行码本中选择的，该上行码本的维度是根据上述SRI所指示的SRS resource的端口数和TRI指示的rank数确定的。其中，TRI指示的rank数也可称为PUSCH传输的层(layer)数。
其中，TPMI域也可称为预编码信息和层数(precoding information and number of layers)域，为便于阐述，下文以TPMI域为例进行相关阐述。
(3)终端设备根据DCI中携带的SRI域和TPMI域，确定PUSCH的预编码矩阵(precoder)及PUSCH的实际传输rank数，以发送PUSCH。
终端设备根据TPMI域确定预编码矩阵之前，还需根据终端设备被配置的传输最大秩数(maxRank)和SRI域指示的SRS resource的端口数，确定预编码指示信息表，如表1所示。表1是“不需要传输预编码矩阵，且天线端口数为2，传输最大秩数为2的预编码信息和层数”(precoding information and number of layers，for 2 antenna ports if tranform precoder is disabled and maxRank＝2)表。表1可简称为预编码信息表、预编码指示信息表、传输预编码矩阵指示(Transmission precoding matrix indicator，TPMI)信息表，或“预编码信息和层数”(precoding information and number of layers)表。终端设备被配置的传输maxRank，是由网络设备通过无线资源管理(radio resource control,RRC)信令为终端设备配置的。天线端口数(antenna ports)等于SRI域指示的SRS resource的端口数。如图1所示，该DCI中SRI域等于2，表示SRI域指示的SRS resource的端口数为2，即天线端口数等于2。
其中，表1中比特映射的索引(Bit field mapped to index)可简称为TPMI域的值。码本子集(codebookSubset)类型是终端设备被配置的。codebookSubset所属的矩阵相干类型包括非相干(non coherent)、部分相干和非相干(partial and non coherent)、全部和部分相干和非相干(fully and partial and non coherent)。如表1所示，DCI中的TPMI域需要4 个比特来指示各种可能的预编码信息和层数，该预编码信息可为TPMI。
表1
Figure PCTCN2021101087-appb-000014
进一步的，假设终端设备支持的码本子集为“全部和部分相干和非相干(fully and partial and non coherent)”，则可确定表1中的一列；进而基于DCI中TPMI域的值，如图1所示，网络设备发送的TPMI域映射的index等于5，则可从该表1中读取预编码指示信息为“1layer，TPMI＝4”。即TRI(PUSCH传输的实际rank数)等于1，预编码指示信息指示的一个预编码矩阵指示TPMI等于4。
进一步的，终端设备根据SRI域和该TRI，确定如表2所示的传输预编码矩阵指示(TPMI)表。从表1中读取的TPMI的值对应表2中TPMI index。
表2
Figure PCTCN2021101087-appb-000015
该表2也可称为预编码指示表、预编码矩阵指示(precoding matrix indicator，PMI)表或预编码矩阵表。基于从表1中读取的TPMI＝4，可从表2中读取该TPMI＝4对应的预编码矩阵是
Figure PCTCN2021101087-appb-000016
故如图1所示，终端设备可基于该预编码矩阵
Figure PCTCN2021101087-appb-000017
传输PUSCH。
可选的，若终端设备根据SRI域和TRI，确定如表3所示的传输预编码矩阵指示(TPMI)表，即SRI域指示的端口数等于2，从表1读取的TRI等于2，可获得如表3所示的传输预编码矩阵指示(TPMI)表。
表3
Figure PCTCN2021101087-appb-000018
该表3也可称为预编码指示表、预编码矩阵指示(precoding matrix indicator，PMI)表或预编码矩阵表。假设从表1中读取的TPMI＝2，则可从表3中读取该TPMI＝2对应的预编码矩阵是
Figure PCTCN2021101087-appb-000019
终端设备可基于该预编码矩阵
Figure PCTCN2021101087-appb-000020
传输PUSCH。
可见，终端设备接收网络设备发送的预编码指示信息后，还需根据终端设备被配置的传输最大秩数和SRI指示的端口数，确定预编码指示信息表；进而，可根据接收的预编码指示信息(即TPMI域的值)从该预编码指示信息表中读取预编码指示(即TPMI的值)和TRI；然后，终端设备利用该TRI和SRI指示的端口数，确定一个预编码指示表；从而，从该预编码指示表中读取TPMI的值对应的预编码矩阵。也就是说，图1所示的上行传输方法中，预编码指示信息是DCI中的TPMI域；该预编码指示信息所指示的预编码指示是该TPMI域的值对应的TPMI。
2、基于非码本的上行传输方法
NCB模式的上行传输方法与上述CB模式的上行传输方法不同，NCB模式中预编码指示是由DCI中的SRI域后获得的。以下结合图2、表4对NCB模式下的上行传输方法进行阐述。请参阅图2，图2是一种NCB模式的上行传输方法的示意图。如图2所示，该上行传输方法从图2中从左到右可包括以下步骤(1)至步骤(4)：
(1)网络设备给终端设备发送信道状态信息参考信号(channel state information reference signal，CSI-RS)；
其中，终端设备被配置为NCB模式，则网络设备可发送CSI-RS。
(2)终端设备收到CSI-RS后测量得到下行信道质量；根据信道互易性和该下行信道质量计算得到上行信道质量；并根据上行信道质量设计多个上行候选预编码矩阵(candidate precoders)，发送多个SRS，其中，每个SRS对应一个预编码矩阵。如图2所示，终端设备分别发送SRS1至SRS4；
其中，CSI-RS与SRS resource之间存在关联关系。例如，多个CSI-RS与多个SRS resource关联，如CSI-RS 1与SRS resource 1至SRS resource 4关联；或者，CSI-RS 1与SRS resource 1、SRS resource 2关联，CSI-RS 2与SRS resource 3、SRS resource 4关联。
或者，CSI-RS与SRS resource set之间存在关联关系。例如，CSI-RS 1与来自SRS resource set 1的SRS resource 1至SRS resource 4关联，CSI-RS 2与来自SRS resource set 2的SRS resource 1至SRS resource 4关联。这样，终端设备可根据CSI-RS后测量得到下行信道质量，获得预编码矩阵后，通过不同的SRS resource发送使用这些预编码矩阵的SRS。因此，终端设备发送的每个SRS对应一个预编码矩阵。
(3)网络设备根据接收到的多个SRS，选择其中接收效果好的SRS对应的precoder， 通过DCI下发给终端设备；
(4)终端设备接收DCI，根据DCI中的SRI域选择对应的precoder和rank数，用以发送PUSCH。
其中，DCI中的SRI(SRS resource indicator)域用于指示网络设备选择的上行预编码矩阵对应的SRS resource的index；该SRI域对应的SRS resource的index的个数表示终端设备传输PUSCH的实际rank数，也可理解为传输层(layer)数。
另外，终端设备根据DCI中的SRI(SRS resource indicator)域确定网络设备选择的上行预编码矩阵对应的SRS resource的index之前，还需根据终端设备被配置的传输最大秩(L_max)数确定预编码指示信息表。该预编码指示信息表也可称为基于非码本的PUSCH传输且L_max的SRI指示表，简称为SRI信息表。
如表4所示，终端设备根据被配置的传输L_max＝3，确定如表4所示的SRI信息表。其中，SRI域的值对应比特位映射的索引。终端设备还需根据终端设备发送SRS resource的个数N SRS，选择表4中的一列。例如，该N SRS＝4，终端设备可从表4中确定最右边一列。进而，若SRI域的值等于8，则终端设备可从表4中读取对应的SRI分别是1,3。从而，终端设备可确定PUSCH的预编码矩阵是SRS resource的索引分别是1和3对应的预编码矩阵，如图2所示。进而，终端设备可利用SRS1和SRS3对应的预编码矩阵发送PUSCH，另外，该SRI域对应的SRS resource的index个数是2，故PUSCH的传输实际秩数等于2。
表4
Figure PCTCN2021101087-appb-000021
可见，终端设备接收网络设备发送的预编码指示信息(SRI域的值)之前，还需根据 终端设备被配置的传输最大秩数，确定预编码指示信息表；进而，还需根据终端设备发送SRS resource的个数N SRS，选择预编码指示信息表中的其中一列；从而，可根据接收的预编码指示信息(即SRI域的值)从该预编码指示信息表的该列中读取预编码指示(即SRI)，进而根据SRI的值的个数确定TRI，以及SRI指示的预编码矩阵作为PUSCH传输的预编码矩阵。也就是说，图2所示的上行传输方法中，预编码指示信息是DCI中的SRI域的值；该预编码指示信息所指示的预编码指示是该SRI域的值对应的SRI。
其中，需要注意的是，CB模式中网络设备确定SRI域所需的比特数时，采用的“N SRS”是终端设备被RRC信令配置的SRS resource的个数；NCB模式中终端设备确定SRI域指示的SRI时，采用的“N SRS”是终端设备发送SRS resource的个数。
可见，无论是CB模式，还是NCB模式，终端设备均需接收预编码指示信息，进而确定PUSCH传输的预编码矩阵。不同的是，CB模式中预编码指示信息为DCI中的TPMI域，NCB模式中预编码指示信息为DCI中的SRI域。相应的，CB模式中的预编码指示是TPMI，NCB模式中的预编码指示是SRI。可选的，如上文所述，也可以称为预编码矩阵指示信息、或传输预编码矩阵指示信息、或预编码信息和层数信息等；相应的，预编码指示可称为预编码矩阵指示、或传输预编码矩阵指示等，为便于阐述，下文以预编码指示信息、预编码指示为例进行阐述。
本申请中，预编码指示信息用于指示M个预编码指示，该M大于或等于1。对于CB模式，预编码指示信息是DCI中的TPMI域的值，相应的，预编码指示信息所指示的M个预编码指示是该TPMI域的值所对应的M个TPMI，每个TPMI指示一个上行预编码矩阵。其中，TPMI也可称为预编码、预编码矩阵。对于NCB模式，预编码指示信息是DCI中的SRI域的值，相应的，该M个预编码指示是该SRI域的值所对应的M个SRI，每个SRI指示一个预编码矩阵。可以理解，SRI域仅为示例，本申请的指示可以通过其他已有域的复用或新增域实现。下文以SRI域为例进行描述。
3、上行频域复用(Frequency Domain Multiplexing，FDM)模式
为了改善PUSCH传输的可靠性，可利用信道在不同域的分集特性和低相关特性进行传输，例如，利用信道的频域分集特性的上行频域复用(Frequency Domain Multiplexing，FDM)模式。该上行FDM模式中，多个频域资源中至少两个频域资源对应不同的预编码矩阵。
请参阅图3(a)，图3(a)是一种上行FDM的通信示意图。如图3(a)所示，假设在两个传输接收点(transmition reception point,TRP)场景中，终端设备传输一个PUSCH，即该PUSCH使用1个冗余版本(Redundancy Version，RV)0。该PUSCH分别在多个子带(subband,SB)上使用不同的预编码矩阵传输。例如，子带数量为2，分别是SB1、SB2；多个信道独立进行信道估计确定上行传输预编码矩阵，如预编码矩阵P1是基于信道[H1]获得的；预编码矩阵P2是基于信道[H2]获得的；终端设备可根据判决条件，如最大信干噪比(Signal to interference and noise ratio)，确定预编码矩阵与子带的对应关系，如在SB1上使用预编码矩阵P1，在SB2上使用预编码矩阵P2。
相应的，如图3(a)所示，TRP1和TRP2分别在全带宽(如SB1和SB2)上接收PUSCH：
TRP1的接收信号分别是：
y1＝[H1][P1]x，y2＝[H1][P2]x；其中，y1是SB1上的接收信号，[P1]是SB1上的预编码矩阵；y2是SB2上的接收信号，[P2]是SB2上的预编码矩阵；x是终端设备的发送信号；[H1]是终端设备与TRP1之间的信道；
TRP2的接收信号分别是：
y3＝[H2][P1]x，y4＝[H2][P2]x；其中，y3是SB1上的接收信号，[P1]是SB1上的预编码矩阵；y4是SB2上的接收信号，[P2]是SB2上的预编码矩阵；x是终端设备的发送信号；[H2]是终端设备与TRP2之间的信道。
进一步的，TRP1将接收信号y1和y2进行联合解调，获得软信息(soft information)1；TRP2将接收信号y3和y4进行联合解调，获得软信息(soft information)2。两个软信息进行合并解码，获得解码后的比特。
可见，图3(a)所示的多站协作的上行FDM模式可获得频选预编码增益和软信息合并增益，从而改善了传输的可靠性。其中，频选预编码增益是指利用不同频域资源关联不同的预编码矩阵，利用频域分集特性，改善传输的可靠性。
4、时域资源聚合(slot aggregation)传输模式
该时域资源聚合传输模式，利用了信道的时域分集特性，通过重复传输PUSCH，以改善PUSCH的可靠性。例如，将相同的数据在多个时域资源上重复发送。由于网络设备会在多个时域资源上接收同一个传输块(transmission block,TB)的同一版本或不同版本的数据，进行合并处理，故能够提升PUSCH传输的鲁棒性。
具体的，假设网络设备调度终端设备在N个时域资源上分别发送N个PUSCH，该N个PUSCH携带同一个传输块TB的同一版本或不同版本的数据。其中，该N个时域资源均使用时域位置最靠前的第一个时域资源的配置信息，如DMRS端口、预编码矩阵和PUSCH的时域资源配置。其中，PUSCH的时域资源配置用于指示PUSCH在每个时域资源中的哪些符号上传输。
其中，网络设备可通过RRC信令通知终端设备是否为时域资源聚合传输模式，如通过RRC信令的上行聚合因子(aggregation-factor-UL)。该aggregation-factor-UL的取值范围为{1,2,3,4}，其中，2、4、8代表连续的2个时域资源、4个时域资源或8个时域资源聚合发送PUSCH，而1代表不进行时域资源聚合传输模式。当该aggregation-factor-UL等于1时，终端设备不采用时域资源聚合传输方法；当该aggregation-factor-UL大于1时，终端设备采用时域资源聚合传输模式。另外，该时域资源聚合传输模式可支持秩数为1的PUSCH传输。
以一个时域资源为一个时隙为例，请参阅图4，图4是一种时隙聚合传输模式的示意图。如图4所示，假设aggregation-factor-UL等于4，该4个时隙(slot)发送相同的数据TB0。由于聚合的4个slot只有第一个slot有对应的DCI，故该4个slot均使用slot0内DCI的配置信息，该配置信息包括预编码信息，如预编码矩阵指示和TRI。也就是说，该时隙聚合传输模式下，无论是CB模式，还是NCB模式，该4个slot均使用相同的预编码矩阵分别传输TB0。
5、频域资源、时域资源
通信系统中的资源，从频率上看被划分为若干个子载波，该若干个子载波可划分为不同粒度大小的频域资源，每个频域资源有对应的序号。例如，一个频域资源可以是一个或多个资源块(resource block，RB)，一个或多个子载波，一个或多个子带(subband,SB)，一个资源块(resource block,RB)，或一个资源块组(resource block group,RBG)等。其中，一个RB中包含的子载波的数量为12个。
其中，用于传输PUSCH的N个频域资源是被调度的PUSCH所占的频域资源范围。该N个频域资源的位置、数量等可通过频域资源配置(frequency domain resource allocation，FDRA)字段指示。具体指示方式例如，该字段可以采用位图bitmap的方式，将整个系统带宽或者部分带宽BWP以预定义的频域资源的粒度划分，一个频域资源对应bitmap中的一个比特，bitmap中的某个比特置0表明相应频域资源未被调度，bitmap中的某个比特置1表明相应频域资源被调度。再例如，该FDRA字段还可指示调度数据所占的频域资源的起始位置和所占的频域资源数量。
通信系统中的资源，从时间上看被划分为若干个符号，如若干个正交频分复用多址(Orthogonal Frequency Division Multiple，OFDM)符号，该若干个符号可划分为不同粒度大小的时域资源。例如，一个时域资源可以是一个或多个无线帧，一个或多个子帧，一个或多个时隙，一个或多个微时隙(mini slot)，一个或多个正交频分复用(orthogonal frequency division multiplexing，OFDM)符号，一个或多个离散傅里叶变换扩频的正交频分复用(discrete fourier transform spread spectrum orthogonal frequency division multiplexing，DFT-S-OFDM)符号等，也可以是多个帧或子帧构成的时间窗口，例如系统信息(system information，SI)窗口。
其中，用于传输PUSCH的S个时域资源是被调度的PUSCH所占的时域资源范围。该S个时域资源的位置、数量以及PUSCH在每个时域资源中的哪些符号上传输等可通过时域资源配置(time domain resource allocation，TDRA)字段指示。具体指示方式例如，以一个时域资源为一个时隙为例，该字段指示调度PUSCH所占的时隙或者子帧的位置，可以是以DCI检测时隙或者子帧为基准的相对位置，或者以系统定义的一个时隙或者子帧为基准的绝对位置。
6、联合接收(joint reception，JT)模式
利用信道的空域分集特性的联合接收(joint reception，JT)模式可通过增加接收孔径，改善传输的可靠性。
请参阅图3(b)，图3(b)是一种JT的通信场景示意图。如图3(b)所示，假设两个TRP协作场景中，终端设备传输一个PUSCH，即该PUSCH使用1个冗余版本(Redundancy Version，RV)0。该PUSCH使用一个宽带的预编码矩阵P，即该预编码矩阵P是基于[H1；H2]获得的。其中，[H1]是终端设备与TRP1之间的信道；[H2]是终端设备与TRP2之间的信道。也就是说，该预编码矩阵P是对多个信道进行联合信道估计获得的，等效于增加接收孔径，即由一个信道接收孔径Nrx增加到两个信道的接收空间2Nrx。
相应的，TRP1和TRP2联合接收该PUSCH的接收信号y＝[H1；H2]Px，其中，x是终 端设备发送PUSCH对应的发送信号。进而，接收信号y经过解调获得soft information 1，该soft information 1经过解码获得解码后的比特。
可见，JT模式中，多个TRP联合接收，相当于增加了接收孔径，进而使得信道估计更加精确，优化了信道对应的预编码矩阵，从而改善传输的可靠性。
为了更好的理解本申请实施例公开的上行传输方法，其次对本申请实施例适用的通信系统进行描述。
本申请实施例可应用于如图3(a)或图3(b)所示的通信系统，该通信系统是以TRP1、TPR2和终端设备为例的，本申请实施例所述的上行传输方法也可应用于包括一个TRP和一个终端设备的通信系统，也就是说，本申请实施例并不限定所应用的通信系统中网络设备、终端设备的数量。
本申请实施例中，预编码指示信息主要以携带于一个下行控制信息中为例进行阐述的。可选的，该预编码指示信息分别指示的M个预编码指示可由多个下行控制信息分别指示，从而使得终端设备获得M个预编码指示。需要说明的是，无论该预编码指示信息携带于一个下行控制信息中，还是携带于两个下行控制信息中，均可以采用本申请实施例所述的M个预编码指示与N个频域资源之间关联关系的各实施方式。
本申请实施例可应用于独立组网，即未来网络中部署的新的基站、回程链路以及核心网等通信系统中，也可应用非独立组网等各种通信系统中。
例如，本申请实施例可用于第五代(5th generation，5G)系统，也可以称为新空口(new radio，NR)系统，或者第六代(6th generation，6G)系统或未来的其他通信系统；或者还可用于设备到设备(device to device，D2D)系统，机器到机器(machine to machine，M2M)系统、长期演进(long term evolution,LTE)系统等等。
本申请实施例中，网络设备可为具有无线收发功能的设备或可设置于该设备的芯片，该网络设备包括但不限于：演进型节点B(evolved node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、网络设备控制器(base station controller，BSC)、网络设备收发台(base transceiver station，BTS)、家庭网络设备(例如，home evolved Node B，或home Node B，HNB)、基带单元(baseband unit，BBU)，无线保真(wireless fidelity，WIFI)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission and reception point，TRP或者transmission point，TP)等；还可以为5G、6G甚至7G系统中使用的设备，如NR系统中的gNB，或传输点(TRP或TP)，5G系统中的网络设备的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点，如基带单元(BBU)，或，分布式单元(DU，distributed unit)，或微微网络设备(Picocell)，或毫微微网络设备(Femtocell)，或，车联网(vehicle to everything，V2X)或者智能驾驶场景中的路侧单元(road side unit，RSU)。
本申请实施例中，终端设备可包括但不限于：用户设备(user equipment，UE)、接入终端设备、用户单元、用户站、移动站、移动台、远方站、远程终端设备、移动设备、用户终端设备、用户代理或用户装置等。再比如，终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强 现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端、前述的V2X车联网中的无线终端或无线终端类型的RSU等等。在一些部署中，gNB可以包括集中式单元(centralized unit，CU)和分布式单元(distributed unit，DU)。gNB还可以包括有源天线单元(active antenna unit，AAU)。CU实现gNB的部分功能，DU实现gNB的部分功能。比如，CU负责处理非实时协议和服务，实现无线资源控制(radio resource control，RRC)，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能。DU负责处理物理层协议和实时服务，实现无线链路控制(radio link control，RLC)层、介质接入控制(medium access control，MAC)层和物理(physical，PHY)层的功能。AAU实现部分物理层处理功能、射频处理及有源天线的相关功能。由于RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令，也可以认为是由DU发送的，或者，由DU和AAU发送的。可以理解的是，网络设备可以为包括CU节点、DU节点、AAU节点中一项或多项的设备。此外，可以将CU划分为接入网(radio access network，RAN)中的网络设备，也可以将CU划分为核心网(core network，CN)中的网络设备，本申请对此不做限定。
可以理解的是，本申请实施例描述的通信系统是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着系统架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
本申请实施例中，JT模式也可以结合FDM模式获得频选增益，进一步改善传输的可靠性。可见，无论是NCB模式，还是CB模式，终端设备均需确定预编码矩阵。然而，对于上行FDM联合JT模式，或上行FDM模式等PUSCH传输增强的模式中，终端设备需要确定的是多个频域资源的预编码矩阵，因此，如何确定多个频域资源的预编码矩阵以获得频选增益是一个亟待解决的问题。
另外，时域资源聚合传输模式中，若信道条件在聚合的多个时域资源内发生了变化，或终端设备发生了移动，则多个时域资源采用DCI配置的一个预编码矩阵传输PUSCH时，会导致解调性能下降，进而无法保证终端设备的上行传输性能。因此，针对该情况如何改善传输性能也是一个亟待解决的问题。
本申请提供一种上行传输方法，该方法中，终端设备接收的预编码指示信息，可指示M个预编码矩阵指示，每个预编码矩阵指示与N个频域资源中的一个或多个频域资源关联；该N个频域资源用于传输PUSCH，所述M大于或等于1，且小于或等于所述N；所述N大于或等于2；进而，终端设备可根据该预编码指示信息确定N个频域资源的预编码矩阵。由于该N个频域资源中至少两个频域资源分别关联不同的预编码矩阵，故可获得PUSCH传输的频选增益。
另外，本申请还提供一种上行传输方法，该方法中，终端设备接收的预编码指示信息， 可包括T个预编码矩阵指示，每个预编码矩阵指示与S个时域资源中的一个或多个时域资源关联；该S个时域资源用于传输PUSCH，所述T大于或等于1，且小于或等于所述S；所述S大于或等于2；进而，终端设备可根据该预编码指示信息确定S个时域资源的预编码矩阵，由于该S个时域资源中至少两个时域资源分别关联不同的预编码矩阵，故有利于保证时域资源聚合模式下终端设备的上行传输性能。
以下分别结合附图对本申请所述的上行传输方法进行阐述。
请参阅图5，图5是本申请实施例提供的一种上行传输方法的流程示意图。如图5所示，该上行传输方法包括但不限于以下步骤：
S101、网络设备生成预编码指示信息，该预编码指示信息用于指示M个预编码指示；每个预编码指示与N个频域资源中的一个或多个频域资源关联；所述N个频域资源用于传输物理上行共享信道PUSCH；所述M大于或等于1，且小于或等于所述N；所述N大于或等于2；
S102、网络设备发送该预编码指示信息；
S103、终端设备接收该预编码指示信息，并根据该预编码指示信息确定N个频域资源的预编码矩阵。
其中，对于CB模式，该预编码指示信息可以为上文所述的DCI中TPMI域；预编码指示信息用于指示M个预编码指示，一个预编码指示可为DCI中TPMI域中的值对应的一个TPMI。对于NCB模式，该预编码指示信息可以为上文所述的DCI中的SRI域；预编码指示信息中的每个预编码指示，可为DCI中SRI域中的值对应的一个SRI。
本申请实施例中，每个预编码指示与N个频域资源中的一个或多个频域资源关联，具体的关联方式包括但不限于以下实施方式1.1至实施方式1.3。也就是说，实施方式1.1至实施方式1.3从预编码指示信息用于指示一个、两个或N个预编码指示分别阐述预编码指示与频域资源之间的关联关系，或频域资源的预编码矩阵的相关内容。
实施方式1.1预编码指示信息用于指示一个预编码指示。
一种情况，该预编码指示与N个频域资源中的第奇数个频域资源关联，该N个频域资源中的第偶数个频域资源的预编码矩阵是利用预定义规则对该预编码指示所指示的预编码矩阵进行变换获得的。
也就是说，M等于1，如上述表1所示，DCI中TPMI域的值对应的行中包括一个TPMI，该TPMI与N个频域资源中的第奇数个频域资源关联；该N个频域资源中的第偶数个频域资源的预编码矩阵是利用预定义规则对该TPMI所指示的预编码矩阵进行变换获得的。
如图6所示，假设用于传输PUSCH的N个频域资源是2个SB，分别是SB1和SB2；TPMI域的值对应的一个TPMI所指示的预编码矩阵为PMx，则该2个SB按照子带的序号从小到大排列(当然也可以从大到小排列)为：SB1、SB2，即第一个SB是SB1，第二SB是SB2，则该TPMI与SB1关联，即SB1的预编码矩阵为PMx；SB2的预编码矩阵是PMx利用预定义规则变换获得的PMy。
如图7所示，假设用于传输PUSCH的N个频域资源是4个SB，分别是SB1至SB4；TPMI域的值对应的一个TPMI所指示的预编码矩阵为PMx，则该4个SB按照子带的序号从小到大排列(当然也可以从大到小排列)依次是：SB1、SB2、SB3、SB4，相应的，第 奇数个SB是SB1，SB3；第偶数个SB是SB2、SB4。那么，如图7所示，该TPMI与SB1，SB3关联，即SB1，SB3的预编码矩阵为PMx；SB2、SB4的预编码矩阵是PMx利用预定义规则变换获得的PMy。
可选的，该预编码指示与N个频域资源中的第偶数个频域资源关联，该N个频域资源中的第奇数个频域资源是利用预定义规则对该预编码指示所指示的预编码矩阵进行变换获得的。其中，该N个频域资源可按照频域资源的序号进行排列。
可选的，该情况描述为：该预编码指示与N个频域资源中的一个多个频域资源之间的关联关系呈梳齿状(comb)，该预编码指示所指示的预编码矩阵以预定义规则变换获得的预编码矩阵与该N个频域资源中的一个多个频域资源之间的关联关系也呈梳齿状(comb)，且该预编码指示所关联的频域资源与该预编码矩阵所关联的频域资源分别是不同的频域资源(也就是说，两个梳齿状的起始位置不同)。其中，两个梳齿状的起始位置、梳齿密度、梳齿偏移量可分别预定义或信令配置。
举例来说，如图7所示，该预编码指示与4个频域资源中的一个多个频域资源之间的关联关系呈梳齿状，即该预编码指示所指示的预编码矩阵PMx与4个频域资源中的一个多个频域资源之间的关联关系呈梳齿状。该梳齿状的起始位置是SB1，梳齿密度是1个SB，梳齿偏移量是1个SB；相应地，预编码矩阵PMx以预定义规则变换获得的PMy与4个频域资源中的一个多个频域资源之间的关联关系呈梳齿状，该梳齿状的起始位置是SB2，梳齿密度是1个SB，梳齿偏移量是1个SB，从而可获得如图7所示的预编码矩阵与SB之间的梳齿状关联关系。
再例如，如图8所示，用于传输PUSCH的8个频域资源以序号从小到大排列(当然也可以从大到小排列)依次为：SB1、SB2、SB3、SB4、SB5、SB6、SB7、SB8。该预编码指示与该8个频域资源中的一个多个频域资源之间的关联关系呈梳齿状，即该预编码指示所指示的预编码矩阵PMx与8个频域资源中的一个多个频域资源之间的关联关系呈梳齿状，该梳齿状的起始位置是SB1，梳齿密度是2个SB，梳齿偏移量是2个SB；相应地，预编码矩阵PMx以预定义规则变换获得的PMy与8个频域资源中的一个多个频域资源之间的关联关系呈梳齿状，该梳齿状的起始位置是SB3，梳齿密度是2个SB，梳齿偏移量是1个SB，从而可获得如图8所示的预编码矩阵与SB之间的梳齿状关联关系。
可选的，上述阐述的关联关系呈梳齿状，可理解为N个频域资源分别关联的预编码矩阵呈梳齿状。
另一种情况，该预编码指示与所述N个频域资源中的前
Figure PCTCN2021101087-appb-000022
个频域资源关联；所述N个频域资源中的后
Figure PCTCN2021101087-appb-000023
个频域资源的预编码矩阵是利用预定义规则对所述预编码指示所指示的预编码矩阵进行变换获得的。其中，
Figure PCTCN2021101087-appb-000024
表示针对N/2向上取整；
Figure PCTCN2021101087-appb-000025
表示针对N/2向下取整。
也就是说，M等于1，如上述表1所示，DCI中TPMI域的值对应的行中包括一个TPMI， 该TPMI与N个频域资源中的前
Figure PCTCN2021101087-appb-000026
个频域资源关联；该N个频域资源中的后
Figure PCTCN2021101087-appb-000027
个频域资源的预编码矩阵是利用预定义规则对该TPMI所指示的预编码矩阵进行变换获得的。
可选的，该情况可描述为：该预编码指示、利用预定义规则对预编码指示所指示的预编码矩阵进行变换获得的预编码矩阵分别与所述N个频域资源之间的关联关系呈一半-一半(half-half)状。或者，该预编码指示所指示的预编码矩阵PMx、利用预定义规则对预编码指示所指示的预编码矩阵进行变换获得的预编码矩阵PMy，该两个预编码矩阵分别关联的频域资源呈一半-一半(half-half)状。
例如，假设用于传输PUSCH的N个频域资源是2个SB，分别是SB1和SB2；TPMI域的值对应的一个TPMI所指示的预编码矩阵为PMx，则该2个SB按照子带的序号从小到大排列(当然也可以从大到小排列)为：SB1、SB2，即第一个SB是SB1，第二SB是SB2，则该TPMI与SB1关联，即SB1的预编码矩阵为PMx；SB2的预编码矩阵是PMx利用预定义规则变换获得的PMy，如图6所示。
如图9所示，假设用于传输PUSCH的N个频域资源是4个SB，分别是SB1至SB4；TPMI域的值对应的一个TPMI所指示的预编码矩阵为PMx，则该4个SB按照子带的序号从小到大排列(当然也可以从大到小排列)依次是：SB1、SB2、SB3、SB4，相应的，前2个SB是SB1，SB2；后2个SB是SB3、SB4。那么，如图8所示，该TPMI与SB1，SB2关联，即SB1，SB2的预编码矩阵为PMx；SB3、SB4的预编码矩阵是PMx利用预定义规则变换获得的PMy。
其中，该实施方式中的预定义规则可包括但不限于：1)对预编码指示所指示的预编码矩阵的相位旋转；2)对预编码指示所指示的预编码矩阵中不同端口或部分端口对应的矩阵数值进行相位旋转；3)对预编码指示所指示的预编码矩阵叠加特定的矩阵。例如，PMy是PMx的不同端口或部分端口对应的矩阵数值分别与(i，-1，-j)中其中一个数值相乘后获得的。
可见，实施方式1.1中在多个频域资源中至少两个频域资源关联不同的预编码矩阵的情况下，预编码指示信息仍可采用类似于表1所示的预编码指示信息表，其中的预编码指示信息的值对应的索引范围可不变，故终端设备根据该预编码指示信息采用该实施方式1.1确定多个预编码矩阵，能够获得频选增益的同时，避免了预编码指示信息所需的开销增加。
实施方式1.2预编码指示信息用于指示两个预编码指示
也就是说，M等于2，所述预编码指示信息用于指示第一预编码指示和第二预编码指示；
一种情况，所述第一预编码指示与所述N个频域资源中的第奇数个频域资源关联；所述第二预编码指示与所述N个频域资源中的第偶数个频域资源关联。
可选的，该情况描述为：第一预编码指示与N个频域资源中的一个多个频域资源之间的关联关系呈梳齿状(comb)，第二预编码指示与该N个频域资源中的一个多个频域资源之间的关联关系也呈梳齿状(comb)，且该预编码指示所关联的频域资源与该预编码矩阵所关联的频域资源分别是不同的频域资源(也就是说，两个梳齿状的起始位置不同)。其 中，两个梳齿状分别的起始位置、梳齿密度、梳齿偏移量可预定义或信令配置。
可选的，上述阐述的关联关系呈梳齿状，可理解为N个频域资源所关联的第一预编码矩阵指示的预编码矩阵呈梳齿状；N个频域资源所关联第二预编码矩阵指示的预编码矩阵呈梳齿状。或者，第一预编码矩阵指示的预编码矩阵所关联的频域资源在该N个频域资源中呈梳齿状；第二预编码矩阵指示的预编码矩阵所关联的频域资源在该N个频域资源中呈梳齿状。
另一种情况，所述第一预编码指示与所述N个频域资源中的前
Figure PCTCN2021101087-appb-000028
个频域资源关联；所述第二预编码指示与所述N个频域资源中的后
Figure PCTCN2021101087-appb-000029
个频域资源关联。
可选的，该情况描述为：第一预编码指示、第二预编码指示分别与所述N个频域资源之间的关联关系呈一半-一半(half-half)状。或者，第一预编码指示所指示的预编码矩阵PMx、第二预编码指示所指示的预编码矩阵PMy分别关联的频域资源呈一半-一半(half-half)状。
也就是说，该两种情况与上述实施方式1.1的不同之处在于，预编码指示信息中可包括2个预编码指示，即PMx是第一预编码指示所指示的预编码矩阵，PMy是第二预编码指示所指示的预编码矩阵。
例如，终端设备根据被配置的传输最大秩数和SRI域指示的SRS resource的端口数，确定如表5所示的预编码指示信息表。该表5中增加了索引x对应的预编码指示，索引x对应两个TPMI。可选，该索引x对应的描述为：1layer：TPMI＝a，b；或者，1layer：TPMI＝a，TPMI＝b；或者，1layer：TPMI＝a，1layer：TPMI＝b。其中，PUSCH传输的实际秩数以一个数值来表示，或者是每个TPMI的层数之和。
表5所示的“比特域映射到索引”(Bit field mapped to index)x对应的条目是在目前的预编码指示信息表中增加的，以指示PUSCH传输增强下的预编码指示，即该条目可指示两个预编码指示。其中，x的值可为各保留字段对应的索引。
可选的，可协议预定义PUSCH传输增强的预编码指示信息表，即采用不同于目前的非PUSCH传输增强的预编码指示信息表，而是新的PUSCH传输增强的预编码指示信息表中各条目均指示两个TPMI的值。
表5
Figure PCTCN2021101087-appb-000030
Figure PCTCN2021101087-appb-000031
例如，用于传输PUSCH的4个SB，按照序号从小到大(当然也可以从大到小排列)依次为：SB1、SB2、SB3、SB4，DCI中TPMI域的值为x，该x对应的TPMI分别是TPMI a，TPMI b，则基于上述实施方式1.2阐述的情况一，可获得的关联关系为：
SB1-TPMI a，SB2-TPMI b，SB3-TPMI a，SB4-TPMI b，或
SB1-TPMI b，SB2-TPMI a，SB3-TPMI b，SB4-TPMI a。
基于上述实施方式1.2阐述的情况而，可获得的关联关系为：
SB1-TPMI a，SB2-TPMI a，SB3-TPMI b，SB4-TPMI b，或
SB1-TPMI b，SB2-TPMI b，SB3-TPMI a，SB4-TPMI a。
进一步的，终端设备根据表5中的TRI和SRI域指示的SRS resource端口数，确定预编码指示表。假设TPMI域的值x在表5中对应的条目是TRI＝1，以及SRI域指示的SRS resource端口数等于4，确定的预编码指示表如表6所示；进而，终端设备可根据TPMI a、TPMI b从表6中读取对应的预编码矩阵。其中，TPMI a、TPMI b为TPMI索引index列中的索引。
表6
Figure PCTCN2021101087-appb-000032
Figure PCTCN2021101087-appb-000033
可见，实施方式1.2中在多个频域资源中至少两个频域资源关联不同的预编码矩阵的情况下，预编码指示信息可采用在目前的预编码指示信息表中增加条目，所增加的条目指示PUSCH传输增强下的预编码指示，即这些条目可包括两个预编码指示。或者，该实施方式中可针对PUSCH传输增强，预定义新的预编码指示信息表，该预编码指示信息表中每个条目可包括两个预编码指示。从而有利于获得频选增益的同时，相对降低终端设备的处理复杂度。
实施方式1.3M等于N，所述预编码指示信息用于指示N个预编码指示。
也就是说，该实施方式中，终端设备可从预编码指示信息表中读取预编码指示信息所指示的N个预编码指示，一个预编码指示关联一个频域资源，从而可获得N个频域资源的预编码矩阵。
可选的，该N个预编码指示可根据N个频域资源的序号大小顺序依次与该N个频域资源关联。
举例来说，假设用于传输PUSCH的N个频域资源是2个SB，分别是SB1和SB2；预编码指示信息用于指示两个预编码指示，分别是TPM1和TPMI2，则可获知SB1与TPMI1关联，SB2与TPMI2关联；或者，SB2与TPMI1关联，SB1与TPMI2关联。
假设用于传输PUSCH的N个频域资源是4个SB，分别是SB1、SB2、SB3、SB4；相应的，预编码指示信息用于指示四个预编码指示，分别是TPM1、TPMI2、TPMI3、TPMI4，则可获知SB1与TPMI1关联，SB2与TPMI2关联，SB3与TPMI3关联，SB4与TPMI4关联；或者，SB4与TPMI1关联，SB3与TPMI2关联，SB2与TPMI3关联，SB1与TPMI4关联。
也就是说，上述实施方式1.1、实施方式1.2中，预编码指示信息表中预编码指示信息对应的预编码指示的个数与用于传输PUSCH的频域资源的个数无关。而该实施方式1.3中，预编码指示信息表中预编码指示信息对应的预编码指示的个数等于用于传输PUSCH的频域资源的个数。例如，如表5中，N等于2时，x对应两个TPMI；若N等于4，则表5中x需要对应4个TPMI，从而分别与4个频域资源关联。
可见，该实施方式中，终端设备可直接根据预编码指示信息所指示的N个预编码指示，获得N个频域资源的预编码矩阵，从而使得PUSCH传输获得频选增益的同时，降低终端设备的处理复杂度。
另外，上述实施方式1.1至实施方式1.3中，DCI中携带一个预编码指示信息，即可获得M个预编码指示，以确定N个频域资源的预编码矩阵。也就是说，DCI中可携带一个预编码指示信息，基于该预编码指示信息即可从预编码指示信息表中获得对应的1个、2个、N个预编码指示。与DCI中需要携带多个预编码指示信息，每个预编码指示信息所指示的一个预编码指示关联一个频域资源，即DCI中需要携带表1中两个index的值才能获得两 个预编码指示的方式相比，上述实施方式1.1至实施方式1.3所述的方法能够降低下行控制信息的开销。
另外，实施方式1.1、实施方式1.2通过预定义规则的方式获得部分频域资源的预编码矩阵，与实施方式1.3直接获得每个频域资源的预编码矩阵的方式相比，可在不增加信令开销的情况下，尽可能的保证性能。
一种可选的实施方式中，M个预编码指示分别指示的预编码矩阵属于同一种码本子集类型；或者，
所述M个预编码指示分别指示的预编码矩阵属于所述终端设备的最大相干能力所对应的预编码矩阵；或者，
所述M个预编码指示分别指示的预编码矩阵属于同一种码本子集类型且属于所述终端设备的最大相干能力所对应的预编码矩阵；或者，
所述M个预编码指示分别指示的预编码矩阵属于预定义的码本子集类型。
也就是说，该实施方式限定了预编码指示信息表中每个索引所需指示的TPMI的个数。例如，上述表6中，TPMI index为0至3的预编码矩阵中只有一个非零值，TPMI index为0至3的预编码矩阵所属的矩阵相干类型为非相干；TPMI index为4至7，以及8至11的预编码矩阵中有两个非零值，TPMI index为4至11的预编码矩阵所属的矩阵相干类型为部分相干；TPMI index为12至27的预编码矩阵中全部为非零值，TPMI index为12至27的预编码矩阵所属的矩阵相干类型为全部相干。因此，该实施方式限制M个预编码指示分别指示的预编码矩阵的矩阵相干类型，预编码指示所需的比特数能够指示表6中的部分预编码矩阵即可，进而，预编码指示信息表中预编码指示信息所需的比特数也相对减少，从而有利于降低信令开销。
例如，以上述实施方式1.2为例，预编码指示信息用于指示两个预编码指示，对于表6的所有预编码矩阵来说，该预编码指示信息需要对应的可能的组合数为
Figure PCTCN2021101087-appb-000034
若采用该实施方式，限定该两个预编码指示分别指示的预编码矩阵的矩阵相干类型为非相干，则该预编码指示信息需要对应的可能的组合数为
Figure PCTCN2021101087-appb-000035
可见，该实施方式能够大大降低预编码指示信息所需的比特数，从而降低DCI的开销。
该实施方式中，网络设备可通过RRC信令为终端设备配置码本子集(codebookSubset)的矩阵相干类型，即上述所述的M个预编码指示分别指示的预编码矩阵所属的矩阵相干类型。
若codebookSubset等于fullyAndPartialAndNonCoherent，表示终端设备需要从所有的矩阵相干类型的预编码矩阵中确定M个预编码指示分别对应的预编码矩阵。例如，codebookSubset等于partialAndNonCoherent，则终端设备从表6所示的部分预编码矩阵，如TPMI index为0至11对应的预编码矩阵中，确定M个预编码指示分别对应的预编码矩阵。
若codebookSubset等于partialAndNonCoherent，表示终端设备需要从矩阵相干类型为部分相干和非相干的预编码矩阵中确定M个预编码指示分别对应的预编码矩阵。例如，codebookSubset等于partialAndNonCoherent，则终端设备从表6所示的部分预编码矩阵， 如TPMI index为0至11对应的预编码矩阵中，确定M个预编码指示分别对应的预编码矩阵。
若codebookSubset等于NonCoherent，表示终端设备需要从矩阵相干类型为非相干的预编码矩阵中确定M个预编码指示分别对应的预编码矩阵。例如，codebookSubset等于NonCoherent，则终端设备从表6所示的部分预编码矩阵，如TPMI index为0至3对应的预编码矩阵中，确定M个预编码指示分别对应的预编码矩阵。
上述实施方式1.1至实施方式1.3主要以CB模式为例进行阐述的，可选的，上述实施方式1.3至实施方式1.3所述的实施方式也可应用于NCB模式。其中，预编码指示信息用于指示M个预编码指示，每个预编码指示与N个频域资源中的一个或多个频域资源关联，该关联关系在NCB模式中有两种解读规则：
解读规则2.1，该关联关系是一个layer上N个频域资源与M个预编码指示的关联关系，故若终端设备传输PUSCH的rank数大于1，则需包括每个layer上N个频域资源与M个预编码指示的关联关系，即SRI域的值对应的条目中应包括各layer上的M个预编码指示。
解读规则2.2，该关联关系是N个频域资源与M个预编码指示的关联关系，终端设备传输PUSCH的rank数由网络设备通过其他参数指示给终端设备。
以下将上述两种解读规则和上述三种实施方式相结合，阐述NCB模式下确定N个频域资源的预编码矩阵的实施方式，该实施方式包括但不限于以下实施方式3.1至实施方式3.3。
实施方式3.1预编码指示信息用于指示一个预编码指示。
基于解读规则2.1，预编码指示信息所指示的预编码指示为SRI；该SRI所指示的SRS resource使用的预编码矩阵是一个layer上N个频域资源中的一个或多个频域资源的预编码矩阵，即该SRI与一个layer上N个频域资源中的一个或多个频域资源关联。
也就是说，预编码指示信息所指示的该预编码指示是SRI域的值对应的条目中一个layer上的SRI，每个layer对应一个SRI，该条目包括的SRI的个数为终端设备传输PUSCH的实际rank数。
例如，终端设备根据被配置的最大传输rank数、N SRS以及DCI中的SRI域的值，从类似于表4中确定的条目中包括SRI 0、SRI 1，则表示终端设备传输PUSCH的实际rank数等于2，以及：
layer 1对应的SRI 0与layer 1上N个频域资源中第奇数个频域资源、第二偶数个频域资源、前

Figure PCTCN2021101087-appb-000037

Figure PCTCN2021101087-appb-000039
个频域资源的预编码矩阵；相应的，预编码矩阵PMx以预定义规则变换获得的预编码矩阵PMy1是layer 1上该N个频域资源中的其他频域资源的预编码矩 阵；
layer 2对应的SRI 1与layer 2上N个频域资源中第奇数个频域资源、第二偶数个频域资源、前

个频域资源、或后
Figure PCTCN2021101087-appb-000043
个频域资源的预编码矩阵；相应的，预编码矩阵PMx2以预定义规则变换获得的预编码矩阵PMy2是layer 2上该N个频域资源中的其他频域资源的预编码矩阵。
基于解读规则2.2，预编码指示信息所指示的预编码指示为SRI；该SRI所指示的SRS resource使用的预编码矩阵是N个频域资源中的一个或多个频域资源的预编码矩阵，即该SRI与N个频域资源中的一个或多个频域资源关联。也就是说，预编码指示信息所指示的该预编码指示是SRI域的值对应的条目中包括一个SRI。
例如，终端设备根据被配置的最大传输rank数、N SRS以及DCI中的SRI域的值，从类似于表4中确定的条目中包括SRI 0，则表示SRI 0与N个频域资源中第奇数个频域资源、第二偶数个频域资源、前

Figure PCTCN2021101087-appb-000045

Figure PCTCN2021101087-appb-000047
个频域资源的预编码矩阵；相应的，预编码矩阵PMx以预定义规则变换获得的预编码矩阵PMy1是该N个频域资源中的其他频域资源的预编码矩阵。
可选的，上述关联关系也可描述为呈梳齿状(comb)，梳齿状的起始位置、梳齿密度、梳齿偏移量可预定义或信令配置。上述关联关系呈一半-一半(half-half)状。相关描述可参见上述实施方式1.1，例如，图6至图9所示的关联模式，此处不再详述。
实施方式3.2预编码指示信息用于指示两个预编码指示。
基于解读规则2.1，预编码指示信息所指示的两个预编码指示为第一SRI和第二SRI；该两个SRI分别指示的预编码矩阵与一个layer上N个频域资源的预编码矩阵，即该两个SRI与一个layer上N个频域资源关联。
也就是说，预编码指示信息所指示的两个预编码指示是SRI域的值对应的条目中一个 layer上的SRI，每个layer对应两个SRI，该条目包括的SRI的个数除以2等于终端设备传输PUSCH的实际rank数。
例如，终端设备根据被配置的最大传输rank数、终端设备发送SRS resource的个数N SRS确定如表7所示的预编码指示信息表。表7中，x、y、z的取值小于对应列的N SRS。
表7
Figure PCTCN2021101087-appb-000048
假设终端设备配置的N SRS等于2，DCI中SRI域的值等于2，以及N等于2，则可从表7中确定一行的条目是0、1、x、y，简称为SRI0、SRI1、SRIx和SRIy，基于解读规则2.1和该实施方式3.2可知，终端设备实际传输的rank数等于2，且可获得如下表8所示的关联关系：

SB 1 SRI0 SRIx
SB 2 SRI1 SRIy
或可获得如下表9所示的关联关系：
表9
  Layer 0 Layer 1
SB 1 SRI0 SRI1
SB 2 SRIx SRIy
可选的，终端设备解读条目SRI0、SRI1、SRIx和SRIy时，若预定义先确定每个layer上N个频域资源关联的SRI，再确定每个layer中每个频域资源关联的SRI，即前两个SRI是一个layer 0中两个SB关联的SRI，后两个SRI是与layer 1中两个SB关联的SRI，进而针对每个layer，确定每个SB关联的SRI，可获得如表8所示的关联关系。
可选的，终端设备解读条目SRI0、SRI1、SRIx和SRIy时，若预定义先确定每个频域资源上两个layer关联的SRI，再确定每个频域资源中每个layer关联的SRI，即前两个SRI是SB1中两个layer关联的SRI，后两个SRI是与SB2中两个layer关联的SRI，进而针对每个SB，确定每个SB关联的SRI，可获得如表9所示的关联关系。
例如，用于传输PUSCH的N个频域资源为SB1至SB4，基于SRI域的值确定的条目是SRI0、SRI1、SRIx和SRIy；若预定义先确定每个layer上4个频域资源关联的SRI，再确定每个layer中每个频域资源关联的SRI，其中，每个layer上的SRI与4个频域资源之间的关联关系是comb状或half-half状，则可获得如表10所示的关联关系，或表11所示的关联关系：

基于解读规则2.2，预编码指示信息所指示的两个预编码指示为第一SRI和第二SRI；该两个SRI分别指示的预编码矩阵分别是N个频域资源的预编码矩阵，即该两个SRI与N个频域资源关联。
例如，假设终端设备配置的N SRS等于2，DCI中SRI域的值等于0，以及N等于2，则可从表7中确定一行的条目是0、x，简称为SRI0、SRIx，基于解读规则2.2和该实施方式3.2可获得如下表14或表15所示的关联关系：
表14
SB 1 SRI0

可选的，上述关联关系也可描述为呈梳齿状(comb)，梳齿状的起始位置、梳齿密度、梳齿偏移量可预定义或信令配置。上述关联关系呈一半-一半(half-half)状。相关描述可参见上述实施方式1.2，此处不再详述。
例如，用于传输PUSCH的N个频域资源为SB1至SB4，基于SRI域的值确定的条目是0、x，简称为SRI0、SRIx；若每个SRI与N个频域资源之间的关联关系是comb状或 half-half状，则可获得如表16所示的关联关系，或表17所示的关联关系，或表18所示的关联关系，或表19所示的关联关系：

实施方式3.3预编码指示信息中包括N个预编码指示。
基于解读规则2.1，预编码指示信息所指示的N个预编码指示分别指示的预编码矩阵是一个layer上N个频域资源的预编码矩阵，即该N个SRI与一个layer上N个频域资源关联。
也就是说，预编码指示信息所指示的N个预编码指示是SRI域的值对应的条目中一个layer上的SRI，每个layer对应N个SRI，该条目包括的SRI的个数除以N等于终端设备传输PUSCH的实际rank数。
例如，假设终端设备配置的N SRS等于3，DCI中SRI域的值等于6，以及N等于3，则可从表7中确定一行的条目是0,1,2,x,y,z，简称为SRI0、SRI1、SRI2、SRIx、SRIy和SRIz，基于解读规则2.1和该实施方式3.3可知，终端设备实际传输的rank数等于2，且预定义先确定每个layer上N个频域资源关联的SRI，再确定每个layer中每个频域资源关联的SRI，可获得如下表20所示的关联关系：
表20
  Layer 0 Layer 1
SB 1 SRI0 SRIx
SB 2 SRI1 SRIy
SB 3 SRI2 SRIz
若预定义先确定每个频域资源上两个layer关联的SRI，再确定每个频域资源中每个layer关联的SRI，则可获得如下表21所示的关联关系：
表21
  Layer 0 Layer 1
SB 1 SRI0 SRI1

可选的，上述针对上行FDM模式，CB模式或NCB模式的上行传输方法进行了阐述。另外，该上行传输方法还可应用于联合接收的通信场景，即用于传输PUSCH的N个频域资源中至少两个频域资源关联不同的预编码矩阵，如通过上述实施方式1.1至实施方式1.3所示的CB模式确定N个频域资源的预编码矩阵，或通过上述实施方式3.1至实施方式3.2所示的NCB模式确定N个频域资源的预编码矩阵，从而使得上行传输过程中不仅能够获得频选增益，还能够增加接收孔径，改善传输性能。
另外，本申请还提供一种上行传输方法，该上行传输方法可应用于时域资源聚合传输模式，该方法包括：终端设备接收的预编码指示信息，可包括T个预编码矩阵指示，每个预编码矩阵指示与S个时域资源中的一个或多个时域资源关联；该S个时域资源用于传输PUSCH，所述T大于或等于1，且小于或等于所述S；所述S大于或等于2；进而，终端设备可根据该预编码指示信息确定S个时域资源的预编码矩阵，由于该S个时域资源中至少两个时域资源分别关联不同的预编码矩阵，故有利于保证时域资源聚合模式下终端设备的上行传输性能。
请参阅图10，图10是本申请实施例提供的又一种上行传输方法的通信示意图。如图10所示，终端设备在时间单元t1上发送的信号x1是PUSCH的RV0版本的数据；终端设备在时间单元t2上发送的信号x2是PUSCH的RV1版本的数据。终端设备在时间单元t1，采用预编码矩阵P1发送x1；终端设备在时间单元t2，采用预编码矩阵P2发送x2；其中，预编码矩阵P1和预编码矩阵P2分别是基于信道[H1]和信道[H2]获得的。信道[H1]和信道[H2]分别是采用独立信道估计获得的。
相应的，如图10所示，TRP1的接收信号：
t1：y1＝H1P1x1；
t2：y2＝H1P2x2；
TRP2的接收信号：
t1：y3＝H2P1x1；
t2：y4＝H2P2x2；
接收信号y1至接收信号y4经过分别解调可得到四个软信息：Soft info 1至Soft info 4，该四个软信息使用不同的RV版本，故经过合并解码，获得解码比特(Decodedbits)。
其中，时间单元t1和时间单元t2可为时隙或微时隙等，本申请不做限定。
可见，在时域资源聚合模式，终端设备在不同的时间单元采用不同的预编码矩阵，使得上行传输不仅能够获得软信息合并增益，还有利于改善传输性能。
该上行传输方法中，预编码指示信息用于指示T个预编码矩阵指示，每个预编码矩阵指示与S个时域资源中的一个或多个时域资源关联中，T个预编码矩阵指示与S个时域资源之间的关联关系可能的实施方式，与上述CB模式下的各实施方式相似，以及与上述NCB模式下的各实施方式也相似，不同之处在于将上述各实施方式中的频域资源替换为时域资源，此处不再详述。
