具体实施方式
下文中将结合附图对本申请的实施例进行说明。
通常的，基站可以根据用户设备(User Equipment，UE)的发送天线的能力确定天线端口数，调度UE发送信道探测参考信号(Sounding Reference Signal，SRS)，SRS用于测量上行信道，也叫信道探测。基站在得到信道测量结果后，根据信道测量结果为后续的上行传输确定多输入多输出(Multiple-Input Multiple-Output，MIMO)参数(包括层数、预编码等)，随后为UE的上行传输指定一个确定的预编码矩阵，即传输预编码矩阵指示(Transmitted Precoding Matrix Indicator，TPMI)。UE使用指定的预编码矩阵对所传输的数据进行预编码，发送给基站。
在新无线接入技术(New Radio Access Technology，NR)系统中，以MIMO多天线方式发送上行传输时，可以分为基于码本的(codebook based)传输和非基于码本的(non codebook based)传输两种。码本(codebook)是预先定义的一组码字，包括至少一个码字(codeword)。每个码字是一个矩阵，用于发送端(UE)多端口的预编码。因此，码字也叫预编码矩阵。码字矩阵的每行代表一个天线端口(antenna port)，每列代表一层(MIMO layer)。例如，表1是基于2个天线端口1层的码本。
表1：使用两个天线端口进行单层传输的预编码矩阵W
Figure PCTCN2020104758-appb-000001
从表1中可以看出，码本中包括6个码字，每个码字是两行一列。码字用TPMI标识。
基站还可以为UE配置SRS资源集合(SRS resource set)，SRS resource set中包括至少一个SRS资源(SRS resource)。SRS resource set的用途可以是以下之一：波束管理、天线切换、码本、非码本。其中，基站调度UE发送用途为码本和非码本的SRS resource set中的SRS resource用于基站测量上行信道，也叫信道探测。基站根据信道探测的结果为后续的上行传输确定传输参数。基站用用途为码本的SRS resource set调度基于码本的上行传输，用用途为非码本的SRS resource set调度非基于码本的上行传输。
基站可能为UE配置不同的SRS资源，UE在不同的SRS资源上发送不同的SRS，那么基站需要为上行传输指示SRS资源指示(SRI，SRS resource indicator)。不同的SRS资源对应不同的发送波束资源(组)，不同的天线面板(panel)(组)，或是对应不同的天线端口的预编码方式。
对于基于码本的传输，基站根据测量的信道在预定义的码本中选择合适的预编码信息(即码字)，用TPMI指示给UE。
对于非基于码本的传输，基站不需要指示TPMI给UE，但是如果UE使用了多天线端口，UE可以自己确定传输的预编码信息。
以上行传输为物理上行共享信道(Physical uplink shared channel，PUSCH)传输为例，基站调度PUSCH传输时，使用物理层控制信令下行控制信息(Downlink Control Information，DCI)的SRI域指示SRS resource set中的一个或多个SRS resource用作PUSCH传输的发送参数参考。例如，UE使用基站指示的SRS resource相同的发送滤波器参数发送调度的PUSCH传输。
对基于码本的PUSCH传输，DCI中的SRI域的比特长度取决于SRS resource set中的SRS resource个数。例如，当SRS resource set中的SRS resource个数为2时，SRI域只需要1比特。
根据SRS resource支持的端口(port)数，DCI还要用预编码信息和层数(Precoding information and number of layers)域指示PUSCH传输的MIMO参数(如MIMO层数、预编码矩阵)。

下面，对本申请提供的传输方法、装置及其技术效果进行描述。
图1为一实施例提供的一种传输方法的流程示意图，如图1所示，本实施例提供的方法适用于发送端，发送端可以为第一通信节点(如终端、或UE)。该方法包括如下步骤。
S110、确定第一通信节点的传输模式。
在一实施例中，确定第一通信节点的传输模式的方法可以包括下述两种方法中的任意一种：
方法一：第一通信节点向第二通信节点(如基站、或网络侧、或节点B(nodeB))上报第一通信节点的能力，并自行确定第一通信节点的传输模式。
方法二：第一通信节点向第二通信节点上报第一通信节点的能力，第二通信节点根据第一通信节点的能力为第一通信节点配置传输模式，并向第一通信节点发送传输模式。
传输模式包括第一模式和第二模式中的至少一项。
在一实施例中，当传输模式为第一模式时，第一通信节点包括以下特性中的至少之一：
第一通信节点将传输的一层在多于X个端口上发送，其中，X由第一通信节点的相干能力确定。当第一通信节点的传输相干特性为非相干(例如pusch-TransCoherence参数为nonCoherent)时，X＝1；和/或，当第一通信节点的传输相干特性为部分相干(例如pusch-TransCoherence参数为partialCoherent)时，X＝2；
第一通信节点使用没有相干性的至少两个端口发送传输的一层。当第一通信节点使用没有相干性的至少两个端口发送传输的一层时，至少两个端口之间的相位差是随机的；或者，当使用超出了第一通信节点的相干能力的TPMI时，允许第一通信节点改变天线端口的相位；
配置给第一模式的第一通信节点的用途为码本的SRS资源集合中的所有SRS资源支持相同的SRS端口数量。
在一实施例中，当传输模式为第二模式时，第一通信节点包括以下特性中的至少之一：
当第一通信节点支持传输在小于配置端口数的端口上发送时，或传输使用的TPMI所对应的预编码矩阵中存在全0行时，或传输使用的TPMI所对应的预编码矩阵中存在零功率端口时，每个端口的功率由第一通信节点的功率能力确定；配置给第二模式的第一通信节点的用途为码本的SRS资源集合中的不同SRS资源支持的不同的SRS端口数量的个数大于或等于1。
SRS资源集合中的不同SRS资源支持的不同的SRS端口数量的个数大于或等于1，即SRS资源集合中的不同SRS资源可以配置不同的SRS端口数量。例如，SRS资源集合中包含3个SRS资源，3个SRS资源的端口数量分别为4、2、1，那么不同的SRS端口数量为3；又如SRS资源集合中包含4个SRS资源，4个SRS资源的端口数量分别为4、1、4、1，那么不同的SRS端口数量为2。
S120、根据传输模式确定码本和发送功率比例中的至少一项。
在一实施例中，当传输模式为第一模式时，根据传输模式确定码本的方法可以包括：

支持满功率状态的传输具有以下特征中的至少之一：
层数为1；
TPMI为保留值；
传输占用与传输相关的SRS资源配置的所有端口发送；传输相关的SRS资源是指调度传输的控制信息(DCI)中包含的SRS资源指示(SRI)所对应的SRS资源。SRS资源都被配置了SRS端口数量，用于MIMO信道测量(sounding)。传输占用与传输相关的SRS资源配置的所有端口发送，是指传输相关的SRS资源配置的所有端口的功率都不为0；
传输在所有非零功率的端口上具有相同的功率；即，第一通信节点使用传输相关的SRS资源配置的所有端口发送传输，各端口具有相同的功率；
传输的预编码在所有非零功率的端口上具有相同的模值；
传输的预编码在所有非零功率的端口上的相位取决于第一通信节点；
传输的预编码取决于第一通信节点。
在一实施例中，满功率状态在调度传输的控制信息中的满功率状态指示域或预编码信息和层数域中指示。
满功率状态在调度传输的控制信息中的满功率状态域指示，是指调度传输的控制信息(DCI)中存在一个域，用于指示满功率状态的开关。例如，取值为1表示打开，取值为0表示关闭。满功率状态在调度传输的控制信息中的预编码信息和层数域指示，是指调度传输的控制信息(DCI)中的预编码信息和层数域中存在一个状态(是预编码信息和层数域对应的域的取值与预编码信息和层数的关系表中的一个状态，也可以称为一个编码点(code point)，或一个项(entry))。例如，codebookSubset参数为nonCoherent的预编码信息和层数域取值为0到11的层数和预编码信息如表2所示，取值为12到15是保留取值，该实施方式中，取值为12表示满功率状态。当控制信息(DCI)中指示codebookSubset参数为nonCoherent时的预编码信息和层数域取值为12，则表示开启该满功率状态。
在一实施例中，扩展TPMI集合具有以下特征中的至少之一：
扩展TPMI集合为codebookSubset参数为fullyAndPartialAndNonCoherent的TPMI集合的全集；扩展TPMI集合为codebookSubset参数为fullyAndPartialAndNonCoherent的TPMI集合的子集；扩展TPMI集合的预编码矩阵的端口之间具有随机的相位差。

上述举例，还可以采用的一种方式是，扩大表4的应用范围，即让表4适用于最大rank(秩)为3、或4。

X1、X2、X3、X4、X5、X6、X7、X8、X9、X10、X11的取值取决于第一通信节点的能力，或为预定义取值。
在一实施例中，SRS资源集合中的所有SRS资源分为X个SRS分组，其中，X为正整数，SRS分组包含的SRS资源由SRS资源编号确定。
SRS资源编号为偶数和奇数的SRS资源分别属于不同的SRS分组；或者，根据SRS资源编号顺序，依次为每个SRS分组分配所需数量的SRS资源；或者，根据SRS资源编号顺序，轮流为每个SRS分组分配SRS资源直到分配完毕。

根据SRS资源编号顺序，依次为每个SRS分组分配所需数量的SRS资源。 假设SRS分组0和SRS分组1的SRS资源数量相同，都为2，则SRS资源编号为0、1的SRS资源属于SRS分组0，SRS资源编号为2、3的SRS资源属于SRS分组1。SRS分组0和SRS分组1的SRS资源数量也可以不同，假设SRS分组0的SRS资源数量为1，SRS分组1的SRS资源数量为3，则SRS资源编号为0的SRS资源属于SRS分组0，SRS资源编号为1、2、3的SRS资源属于SRS分组1。SRS分组的SRS资源数量(也叫，SRS分组所需的SRS资源数量)由第二通信节点配置或指示，或由预定义信息确定。
根据SRS资源编号顺序，轮流为每个SRS分组分配SRS资源直到分配完毕。即，SRS资源编号0分配给SRS分组0，SRS资源编号1分配给SRS分组1，SRS资源编号2分配给SRS分组0，SRS资源编号3分配给SRS分组1。

下面罗列一些示例性实施方式，用于说明本申请实施例提供的传输方法。
在第一个示例性实施方式中，为支持基于码本的PUSCH的满功率传输，RRC配置的参数SRS resource set可以支持配置不同port数量的多个SRS resource。UE需要获得DCI中的SRI值，根据该SRI的SRS resource所支持的端口数才能确定预编码信息和层数域的大小。但是预编码信息和层数域的大小最好根据RRC的信息获得，而不是根据同一DCI中的其他域确定。因此，预编码信息和层数域的大小由SRS resource set中的SRS resource的port数量中的最大port数确定。
当指示的SRI的对应的SRS resource的port数小于最大port数时，预编码信息和层数域实际需要的bit数也可能比较小，此时，预编码信息和层数域中除实际需要的比特(bit)数(即必要指示比特)外的多余的bit是实际需要的bit数的重复，如此，可以提高接收鲁棒性。
或者，当指示的SRI的对应的SRS resource的port数小于最大port数时，
预编码信息和层数域实际需要的bit数也可能比较小，此时，预编码信息和层数域中除实际需要的bit数(即必要指示比特)外的多余的bit设置为预定义的值，如此，预定义的值可以用于接收校验。
例如，SRS resource set支持3个SRS resource，在DCI中分别用SRI 0、SRI1和SRI 2表示。其中，SRI 0的SRS resource支持4port，SRI 1的SRS resource支持2port，SRI 2的SRS resource支持1port。那么DCI中的预编码信息和层数域的大小按照SRS resource set中的SRS resource的port数量中的最大port数，即4port确定。可以参见表2和表3。
假设当UE的最大rank数为2并且codebookSubset参数为nonCoherent，则预编码信息和层数域的大小是4bit。图4为一实施例提供的一种DCI和预编码信息和层数域的对应关系图。如图4所示，当DCI中指示SRI 0时，预编码信息和层数域有12个有效的指示，4bit都是有效的比特，分别用b_x，b_x+1，b_x+2，b_x+3指示4个比特。当DCI中指示SRI 1时，预编码信息和层数域有3个有效的指示，见表4，预编码信息和层数域的大小是2bit。即比特b_x，b_x+1是实际需要的比特，比特b_x+2，b_x+3是多余的比特，b_x+2和b_x+3可以承载与比特b_x和b_x+1相同的内容；或者，多余的两个bit设置为预定义的值，例如，比特b_x+2和b_x+3设置为比特“00”。当DCI中指示SRI 2时，由于只有1bit，因此，预编码信息和层数域不需要指示TPMI和层数，预编码信息和层数域实际需要的比特数为0，此时，比特b_x，b_x+1，b_x+2，b_x+3设置为 比特“0000”。
在第二个示例性实施方式中，为支持基于码本的PUSCH的满功率传输，RRC配置的参数SRS resource set可以支持配置不同port数量的多个SRS resource。UE需要获得DCI中的SRI值，根据该SRI的SRS resource所支持的端口数才能确定预编码信息和层数域的大小。但是，预编码信息和层数域的大小最好根据RRC的信息获得，而不是根据同一DCI中的其他域确定。在上述第一个示例性实施方式中，预编码信息和层数域的大小由SRS resource set中的SRS resource的port数量中的最大port数确定。此处提出另外一种方式，将SRI信息分为两部分，分别承载于DCI中的两个域中。如下：
将SRI信息分为两部分：第一部分指示SRS的分组，称为第一SRS信息，第二部分是指SRS分组内SRS资源的编号，称为第二SRS信息。第一SRI信息与空间关系、面板、波束中的至少一项相关联；第二SRI信息与预编码信息和层数联合指示。
DCI中包括指示第一SRI信息的域，以及第二SRI信息与预编码信息和层数联合指示的信息域。
例如，SRS resource set支持6个SRS resource，这6个SRS resource分为2组，第1组为SRI 0-0、SRI 0-1和SRI 0-2，支持的port数分别为4、2、1。第2组为SRI 1-0、SRI 1-1和SRI 1-2，支持的port数分别为4、2、1。由于SRS resource set中包含2组SRS resource，DCI中包括1比特指示第一SRI信息的域。0表示第1组，1表示第2组。
第二SRI信息是指第一SRI信息指示的SRI分组内SRI的编号，该信息与预编码信息和层数联合指示。根据“第二SRI信息与预编码信息和层数联合指示的信息域”获得第二SRI信息的天线端口数，根据天线端口数确定SRI分组内的SRI的编号。如下表12所示，当第一SRI信息为1，“第二SRI信息与预编码信息和层数联合指示的信息域”的值为4 antenna port时，则对应SRI 1-0；当第一SRI信息为0，“第二SRI信息与预编码信息和层数联合指示的信息域”的值为1 antenna port时，则对应SRI 0-2。
表12：最多4端口天线的天线端口数、预编码信息和层数(传输预编码非使能且maxrank＝2或3或4)

Figure PCTCN2020104758-appb-000016
将SRI信息分为两部分指示的优点在于节省了DCI指示SRI的开销。在上述第一个示例性实施方式中，SRI如果在一个域中指示，则需要3比特，分到两个域中，则第一SRI信息需要1比特，额外的第二SRI信息指示只给预编码信 息和层数域增加了1比特，或者不增加额外的比特。最大天线端口数为4，最大rank为2、3、4的情况下，对codebookSubset参数为fullyAndPartialAndNonCoherent和partialAndNonCoherent的UE，增加了1比特，对codebookSubset参数为nonCoherent的UE，没有增加比特。相当于SRI信息在DCI中只需要1比特或2比特的开销，相比于3比特的开销节省了1到2比特。对于1 antenna port和1layer的情况，没有多天线，因此没有TPMI用于指示预编码。
对最大天线端口数为4，最大rank为1的情况下，如下表13所示，对codebookSubset参数为nonCoherent和partialAndNonCoherent的UE，没有增加比特，对codebookSubset参数为fullyAndPartialAndNonCoherent的UE，增加了1比特。

maxRank＝2，maxRank＝3还可以独立设置表格，减小开销。
参考表12可知，表12是对maxRank＝2 or 3 or 4的情况，根据需要，该表也可以分为3张表，分别对应maxRank＝2，maxRank＝3和maxRank＝4。maxRank＝2，maxRank＝3的预编码信息和层数信息取值是maxRank＝4的预编码信息和层数信息取值的子集。这样maxRank＝2，maxRank＝3的预编码信息和层数域的比特数可能小于maxRank＝4的预编码信息和层数域的比特数。
例如，SRS resource set支持4个SRS resource，这4个SRS resource分为2组，第1组为SRI 0-0、SRI 0-1，支持的port数分别为2、1。第2组为SRI 1-0、SRI 1-1，支持的port数分别为2、1。由于SRS resource set中包含2组SRS resource，DCI中包括1比特指示第一SRI信息的域。0表示第1组，1表示第2组。
第二SRI信息是指第一SRI信息指示的SRI分组内SRI的编号，该信息与预编码信息和层数联合指示。根据“第二SRI信息与预编码信息和层数联合指示的信息域”获得第二SRI信息的天线端口数，根据天线端口数确定SRI分组内的SRI的编号。
将SRI信息分为两部分指示的优点在于节省了DCI指示SRI的开销。上述的4个SRS resource的SRI如果在一个域中指示，则需要2比特，分到两个域中，则第一SRI信息需要1比特，额外的第二SRI信息指示只给预编码信息和层数域增加了1比特，或者不增加额外的比特。参见表14，最大天线端口数为2，最大rank为2的情况下，没有增加比特。相当于SRI信息在DCI中只需要1比特或2比特的开销，相比于2比特的开销在一些情况下节省了1比特。需要注意的是，对于1 antenna port和1 layer的情况，没有多天线，因此没有TPMI用于指示预编码。

相关技术中，基于码本的PUSCH传输使用多天线端口发送时，每个天线端口只能使用最大1/N的最大发送功率，N为UE支持的最大天线端口数量。当TPMI对应的预编码矩阵中有天线端口在所有层上都是0元素时，表示该PUSCH传输在这些天线端口上无功率。其他天线端口的功率之和不能达到UE的最大发送功率。例如，表1的TPMI 0指示的预编码矩阵
Figure PCTCN2020104758-appb-000021
由于一个天线端口是0，所以只支持发送一半的功率。随着技术的发展，器件成本越来越低，单个天线端口支持满功率也成为可能。
另外，相关技术中，如表2到表5所示，当codebookSubset参数为fullyAndPartialAndNonCoherent时支持为UE指示TPMI的全集，而当codebookSubset参数为partialAndNonCoherent和NonCoherent时，为UE指示的TPMI只支持部分TPMI集合。其原因是避免不具有coherent能力的天线端口同时传输。例如，对具有2天线端口的non coherent能力的UE，发送1层传输时，只能使用天线端口选择的预编码矩阵，如
Figure PCTCN2020104758-appb-000022
而不能使用2天线端口的预编码矩阵，如
Figure PCTCN2020104758-appb-000023
从而导致发送1层的传输时，无法使用2个天线端口，从而无法达到满功率。
为解决上述问题，本申请从两个方面对相关技术进行改进：
第一模式：对codebookSubset参数为partialAndNonCoherent和NonCoherent的UE可支持的TPMI集合进行扩展。
第二模式：基站为UE配置至少一个SRS resource set，SRS resource set包括至少一个SRS resource。当多于1个SRS resource时，SRS resource支持的port数可以不同。支持按TPMI确定UE能达到的功率能力。
例如，UE支持最大4天线端口，基站为UE配置1个用途为码本的SRS resource set，其中包括3个SRS resource。3个SRS resource支持的port数分别为4、2、1。其中2port和1port的SRS resource支持的port数比最大port数4小，所以这两个SRS resource可能是虚拟的port，即多个物理天线链路(chain)形成一个port，也可能UE决定只使用部分物理天线链路发送2port和1port的上行传输，总之，物理天线链路对基站是透明的。所以UE需要告知基站其在各个port数量的SRS resource的不同的TPMI的功率能力。
在第三个示例性实施方式中，对第一模式，本申请支持以下之一的扩展方式：
方式1：对codebookSubset参数为partialAndNonCoherentnonCoherent的UE，支持的TPMI集合扩展为codebookSubset参数为fullyAndPartialAndNonCoherent的TPMI集合的全集。
对于codebookSubset参数为partialAndNonCoherent和nonCoherent的UE，新扩充的TPMI的预编码矩阵超出了UE的coherent能力，因此，基站不要求UE能以TPMI对应的预编码矩阵所要求的天线端口的相位差发送上行传输。对于超过UE的coherent能力的TPMI的预编码矩阵，UE可能会改变天线端口的相位差。
方式2：对codebookSubset参数为partialAndNonCoherent和nonCoherent的UE，支持的TPMI集合扩展为codebookSubset参数为fullyAndPartialAndNonCoherent的TPMI集合的子集。如表16、17、18、19所示。

对天线端口数为4的情况，codebookSubset参数为nonCoherent的UE，预编码信息和层数域需要扩展，包括以下至少之一：
1 layer:TPMI＝4；1 layer:TPMI＝8；1 layer:TPMI＝12；2 layers:TPMI＝6；2 layers:TPMI＝14；3 layers:TPMI＝1；3 layers:TPMI＝3；4 layers:TPMI＝1；4 layers:TPMI＝3。

扩展的预编码信息和层数信息与预编码信息和层数域的取值的对应关系可以有多种实现方式。如表16、17所示。
表16是对maxRank＝2 or 3 or 4的情况，根据需要，该表也可以分为3张表，分别对应maxRank＝2，maxRank＝3，maxRank＝4。maxRank＝2，maxRank ＝3的预编码信息和层数信息取值是maxRank＝4的预编码信息和层数信息取值的子集。这样maxRank＝2，maxRank＝3的预编码信息和层数域的比特数可能小于maxRank＝4的预编码信息和层数域的比特数。
对天线端口数为2的情况，codebookSubset参数为nonCoherent的UE，预编码信息和层数域需要扩展，包括以下至少之一：
1 layer:TPMI＝2；2 layer:TPMI＝1。
扩展的预编码信息和层数信息与预编码信息和层数域的取值的对应关系可以有多种实现方式。如表18、19所示。
方式3：对codebookSubset参数为partialAndNonCoherent和nonCoherent的UE，支持的TPMI集合扩展为支持新的TPMI集合。新的TPMI集合主要针对不具有coherent能力的port间的相位差是任意相位差，或UE确定的相位差的情况，如表20、21、22、23、24和25所示。

其中，α，β，γ是恒模复数。
在使用这些新的TPMI的情况下，码本集合的扩展TPMI的取值也要更新：
对天线端口数为4的情况，codebookSubset参数为nonCoherent的UE，预编码信息和层数域需要扩展，包括以下至少之一：
1 layer:TPMI＝28；1 layer:TPMI＝29；1 layer:TPMI＝30(见表21或22)；2 layers:TPMI＝22(见表24)；3 layers:TPMI＝7(见表25)。
对天线端口数为4的情况，codebookSubset参数为partialAndNonCoherent的UE，预编码信息和层数域需要扩展，包括以下至少之一：
1 layer:TPMI＝31；1 layer:TPMI＝32；1 layer:TPMI＝33；1 layer:TPMI＝34(见表21或22)；1 layer:TPMI＝35；1 layer:TPMI＝36；1 layer:TPMI＝37；1 layer:TPMI＝38(见表21)。
对天线端口数为2的情况，codebookSubset参数为nonCoherent的UE，预 编码信息和层数域需要扩展，包括以下至少之一：
1 layers:TPMI＝5(见表20)。
在第四个示例性实施方式中，是基于TPMI(组)/天线端口上报功率能力的设计。
对第二模式，支持按TPMI确定能达到的功率能力。
UE针对不同的port数，分别上报其支持的TPMI的功率能力。
假定不扩展UE支持的TPMI集合，即UE支持的TPMI见表2-5所示，则UE上报其支持所有TPMI的可以达到的功率能力。
在一实施例中，UE针对不同的port数，分别上报其支持的TPMI集合中预编码矩阵存在全零port的TPMI的功率能力。
假定不扩展UE支持的TPMI集合，即UE支持的TPMI见表2-5所示，UE针对不同的port数，分别上报其支持的TPMI集合中预编码矩阵存在全零port的TPMI的功率能力。
预编码矩阵存在全零port的TPMI是指，该TPMI对应的预编码矩阵存在元素全为0的行。预编码矩阵的行与天线端口一一对应，元素全为0的行，即对应一个预编码元素全为0的天线端口，也叫零功率天线端口。如表1中的TPMI0对应的预编码矩阵
Figure PCTCN2020104758-appb-000037
的第2行即为全0，UE应该为该TPMI上报其支持的功率能力。又如表8中的TPMI 0对应的预编码矩阵
Figure PCTCN2020104758-appb-000038
的第3、4行为全0，UE应该为该TPMI上报其支持的功率能力。
在一实施例中，天线端口数为4时，存在全零port的TPMI包括以下至少之一：
1 layer:TPMI＝0、1、...11；2 layers:TPMI＝0、1、2、3、4、5；3 layers:TPMI＝0。
天线端口数为2时，存在全零port的TPMI包括以下至少之一：
1 layer:TPMI＝0、1。
在一实施例中，根据UE的coherent能力，仅支持non coherent能力或partial coherent能力的UE上报其支持的TPMI的功率能力。
在一实施例中，根据UE的coherent能力，仅支持non coherent能力或partial  coherent能力的UE针对不同的port数，分别上报其支持的TPMI集合中预编码矩阵存在全零port的TPMI的功率能力。
在一实施例中，所有coherent能力的UE针对不同的port数，分别上报其支持的TPMI集合中预编码矩阵存在全零port的TPMI的功率能力。
在一实施例中，支持第二模式的UE针对不同的port数，分别上报其支持的TPMI集合中预编码矩阵存在全零port的TPMI的功率能力。
上报TPMI的功率能力可以为：是否能达到UE的最大发送功率，或TPMI的支持的最大功率等级。支持的最大功率等级是指TPMI所支持的最大功率与UE的最大发送功率的比值，如1，1/2，1/4。
除了上述基于TPMI上报功率能力，UE还可以基于天线端口上报功率能力。
天线端口的功率能力可以与TPMI的功率能力相同，即是否能达到UE的最大发送功率，或天线端口支持的最大功率等级。支持的最大功率等级是指天线端口独立支持的最大功率与UE的最大发送功率的比值，如1，1/2，1/4。
对于支持4个天线端口的UE，天线端口编号为0、1、2、3，分别上报4个天线端口独立支持的功率能力。例如，天线端口0支持的最大功率等级为1，天线端口1支持的最大功率等级为1/2，天线端口2、3支持的最大功率等级都为1/4。则每个天线端口需要2比特，4个天线端口需要8比特。如果天线端口的功率能力用是否能达到UE的最大发送功率表达，则每个天线端口需要1比特，只有天线端口0能达到UE的最大发送功率，其余天线端口都不能达到，这样4个天线端口需要4比特。
对于支持2个天线端口的UE，天线端口编号为0、1，分别上报2个天线端口独立支持的功率能力。例如，天线端口0支持的最大功率等级为1，天线端口1支持的最大功率等级为1/2。则每个天线端口需要2比特，2个天线端口需要4比特。如果天线端口的功率能力用是否能达到UE的最大发送功率表达，则每个天线端口需要1比特，只有天线端口0能达到UE的最大发送功率，天线端口1达不到，这样2个天线端口需要2比特。
在一实施例中，考虑实际UE的多PA(parameter)参数(UE专用参数)部署的特点，可以优化需要上报功率的TPMI的组合。
全零(0)port也叫做零port、或零功率port。
本文所述的port(端口)可以包括以下之一：天线端口、参考信号端口、SRS端口、DMRS(解调参考信号)端口。
考虑实际应用中的PA的限制，可以优化TPMI支持满功率(full power)的 方式。
PA的限制可以是：如果只有部分天线端口支持满功率，那么能支持满功率的部分天线端口是天线端口编号较小的，或者按预先定义的天线端口顺序比较靠前的。
对于支持4个天线端口的UE，天线端口编号为0、1、2、3，可能支持以下满功率方式：
1、仅编号为0的天线端口支持满功率；2、仅编号为0和1的天线端口独立支持满功率；3、仅编号为0和2的天线端口独立支持满功率；4、4个天线端口都独立支持满功率。
UE上报以上之一的功率能力信息给基站，则基站根据这些功率能力信息得到TPMI的功率能力，确定对UE的传输使用的预编码矩阵。
4天线端口需要指示以上4种方式之一，需要2比特。
2天线端口需要指示以下2种方式之一，需要1比特：
1、仅编号为0的天线端口支持满功率；2、编号为0和1的天线端口独立支持满功率。
在一实施例中，UE也可以只报单层的单个天线端口为非零功率的TPMI的功率能力。对于有多个天线端口的非零功率的TPMI，以及多层的TPMI，其支持的最大功率由单层的单个天线端口为非零功率的TPMI的功率能力确定。
例如，对4端口，仅报1层的TPMI为0～3的最大功率。假设TPMI 0和TPMI 1支持UE的最大发送功率，TPMI 2和TPMI 3支持的最大功率为1/4的UE的最大发送功率。那么，表7中的TPMI 4
Figure PCTCN2020104758-appb-000039
可以支持的最大功率为3/2倍的UE的最大发送功率，考虑到最大发送功率不超过UE的最大发送功率，所以表7中的TPMI 4可以支持的最大功率为1倍的UE的最大发送功率。对于多层的TPMI也是类似，如表8中的TPMI 0，即矩阵为
Figure PCTCN2020104758-appb-000040
支持的最大功率为1倍的UE的最大发送功率。
上述端口支持满功率的方式也可以用于支持TPMI的满功率方式。例如，对于支持4个天线端口的UE，可能支持以下满功率方式：
1、4天线端口1层的TPMI 0支持满功率；2、4天线端口1层的TPMI 0和 TPMI 1支持满功率；3、4天线端口1层的TPMI 0和2都支持满功率；4、4天线端口1层的TPMI 0到3都支持满功率。
UE上报以上之一的功率能力信息给基站，则基站根据这些功率能力信息得到TPMI的功率能力，确定对UE的传输使用的预编码矩阵。
4天线端口需要指示以上4种方式之一，需要2比特。
2天线端口需要指示以下2种方式之一，需要1比特：
1、2天线端口1层的TPMI 0支持满功率；2、2天线端口1层的TPMI 0和TPMI 1支持满功率。
在第五个示例性实施方式中，描述了SRS资源集合配置的限制。
对所述第一通信节点，所述SRS资源集合中的SRS资源具有以下特征的至少之一：
SRS分组的数量不超过预定义值X1；例如，X1＝2。
SRS资源集合中的SRS资源所关联的空间关系数量不超过预定义值X2；例如，X2＝2。
SRS资源集合中的SRS资源所关联的面板数量不超过预定义值X3；
SRS资源集合中的SRS资源所关联的端口数量中不同端口数量的个数不超过预定义值X4；例如，X4＝2。对最大2port：对非相干的UE，SRS资源集合包括两个SRS资源，分别配置1port和2port；对相干的UE，SRS资源集合包括1个SRS资源，配置2port。对最大4port：对非相干的UE，SRS资源集合包括两个SRS资源，分别配置1port和2port；对部分相干的UE，SRS资源集合包括两个SRS资源，分别配置2port和4port；对相干的UE，SRS资源集合包括1个SRS资源，配置4port。
SRS资源集合中的SRS资源的数量不超过预定义值X5；
