下面对本申请实施例提供的能力信息上报方法、装置及终端中涉及的一些概念和/或术语做一下解释说明。
基于码本的物理上行共享信道(Physical Uplink Shared Channel，PUSCH)传输模式：
网络侧为用户设备UE(也可以称为终端)配置用于基于码本传输的上行探测参考信号(Sounding Reference Signal，SRS资源集，每个SRS资源集包含至少一个SRS资源。UE根据配置的至少一个SRS资源发送SRS，从而网络侧通过接收UE发送的SRS来获得UE期望的上行信道，并基于此来确定UE基于PUSCH传输的波束、预编码矩阵、调制和编码方案(Modulation and coding scheme，MCS)等，并通过调度PUSCH的下行控制信息(Downlink Control Information，DCI)来通知UE。
然后，UE接收调度PUSCH的DCI，并基于DCI中指示的传输预编码矩阵索引(Transmitted Precoding Matrix Index，TPMI)域从一个预定义的码本中选择一个用于所调度PUSCH传输的预编码矩阵。UE会根据所指示的TPMI 对上行数据进行预编码后映射到对应的PUSCH资源上进行传输。其中，DCI中指示的TPMI的指示示例如下表1所示。
表1:4个天线端口的预编码信息和层数，当变换预编码器(transform precoder)被禁用时，最大的秩(Rank)＝2或3。
基于非码本的PUSCH传输模式：
网络侧为UE配置用于基于非码本传输的SRS资源集，每SRS资源集包含至少一个SRS资源。首先UE在网络侧配置的非零功率(Non-Zero Power，NZP)信道状态信息(Channel State Information，CSI)-参考信号(Reference Signal)资源上检测网络侧发送的NZP CSI-RS(非零功率信道状态信息-参考信号)，来获得下行信道状态信息。根据信道互易性，该下行信道信息可以近似等效为上行信道信息。UE根据上行信道信息来计算候选的用于上行传输的预编码矩阵，并基于候选的预编码矩阵中的预编码矩阵对SRS进行预编码并发送，网络侧根据测量预编码后的SRS来进一步确定PUSCH传输所使用的预编码矩阵，并通过调度PUSCH的DCI来通知UE。
具体的，网络侧可以基于DCI的SRS资源指示(SRS resource indicator，SRI)域，从一个预定义SRI索引表中选择一个SRS资源索引对应的一个子集，即SRI组来通知UE PUSCH的预编码采用的预编码矩阵，指示示例如下表2。

例如，在上述(1)中，终端的每个相干天线端口组中的天线端口的个数可以为：1、2、4个、6或8。
例如，在上述(2)中，如图4所示，假设终端包括8个天线端口，这8个天线端口的天线端口标识分别为：1000、1001、1002、1003、1004、1005、1006和1007，其中，如图4中的(a)所示，终端的相干天线端口组中的天线端口标识的组合可以包括以下至少部分组合：组合1{1000，1004，1001，1005}、组合2{1002，1006，1003，1007}、组合3{1001，1005，1002，1006}；或者，如图4中的(b)所示，终端的相干天线端口组中的天线端口标识的组合可以包括以下至少部分组合：组合4{1000，1004，1001，1005}、组合5{1000，1004，1002，1006}、组合6{1002，1006，1003，1007}和组合7{1001，1005，1003，1007}。

可以理解，当终端的相干天线端口组中的天线端口的个数为2、4、6或8时，表示终端的2个、4个、6个或8个天线端口为一组相干天线端口。
可选地，对于支持8天线传输的终端来说，2个天线端口、4个天线端口和6个天线端口为一组相干天线端口也可以描述为部分相干；8个天线端口为一组相干天线端口也可以描述为全相干。

可选地，本申请实施例中，对于2个天线端口为一组相干天线端口的预编码矩阵，该预编码矩阵的一列中最大只有四个元素非零。
可以理解，本申请实施例中，网络侧设备根据终端上报的能力(例如天线相干能力信息)配置满足该能力的终端的上行传输的预编码。
可选地，本申请实施例中，上述(1)和(2)均可以指示终端支持的每组相干天线端口中的天线端口的个数。
可选地，本申请实施例中，若终端上报支持4个天线端口为一组相干天线端口，则表示：终端同时支持2个天线端口为一组相干天线端口，或者终端同时支持所有天线端口都非相干；
若终端上报支持6个天线端口为一组相干天线端口，则表示：终端同时支持2个和/或4个天线端口为一组相干天线端口，或者终端同时支持所有天线端口都非相干；
若终端上报支持8个天线端口为一组相干天线端口，则表示：终端同时支持2个天线端口、4个天线端口和6个天线端口中至少之一为一组相干天线端口，或者终端同时支持所有天线端口都非相干。
需要说明的是，本申请实施例中的天线端口非相干可以理解为这些天线端口间都不(或不需要)做校准。
可选地，本申请实施例中，上述分组方式可以包括以下至少一项：2个天线端口为一组相干天线端口；4个天线端口为一组相干天线端口。
可选地，本申请实施例中，上述分组方式可以包括以下至少一项：2个天线端口为一组相干天线端口；4个天线端口为一组相干天线端口、6个天线端口为一组相干天线端口、8个天线端口为一组相干天线端口。
可选地，本申请实施例中，若终端支持6天线传输，则上述分组方式可以包括以下至少一项：
1)、将6个天线端口分为3组相干天线端口，其中，每组相干天线端口中包括2个天线端口。
2)、将6个天线端口分为2组相干天线端口，其中，1组相干天线端口中包括2个天线端口，另1组相干天线端口中包括4个天线端口。
上述1)和2)中的分组方式也可以描述为部分相干。
若终端支持8天线传输，则上述分组方式可以包括以下至少一项：
1)、将8个天线端口分为2组相干天线端口，其中，每组天线端口中包括4个天线端口。
2)、将8个天线端口分为4组相干天线端口，其中，每组相干天线端口中包括2个天线端口。
3)、将8个天线端口分3组相干天线端口，其中，2组相干天线端口中分别包括2个天线端口，1组相干天线端口中包括4个天线端口。
上述1)、2)和3)中的分组方式也可以描述为部分相干。
需要说明的是，每组相干天线端口中的天线端口的天线端口标识可以为连续的，也可以为不连续的。
示例性地，以每组相干天线端口中的天线端口的天线端口标识连续，且8个天线端口分为3组相干天线端口为例，假设8个天线端口按照天线端口标识依次增大的顺序排列，那么：
1)、前4个天线端口为第一组相干天线端口，第5个天线端口和第6个天线端口为第二组相干天线端口，第7 个天线端口和第8个天线端口为第三组相干天线端口；即4+2+2。或者，
2)、前2个天线端口为第一组相干天线端口，第3个天线端口至第6个天线端口为第二组相干天线端口，第7个天线端口和第8个天线端口为第三组相干天线端口；即2+4+2。或者，
3)、前2个天线端口为第一组相干天线端口，第3个天线端口和第4个天线端口为第二组相干天线端口，第5个天线端口至第8个天线端口为第三组相干天线端口；即2+2+4。
可选地，本申请实施例中，上述两组天线端口相干类型中的每组天线端口相干类型可以包括以下至少一项：完全相干、部分相干、非相干。
本申请实施例中，若一组天线端口相干类型为完全相干，则表示该组天线端口中的所有天线端口之间的相干性满足预设相干条件，例如该组天线端口中的所有天线端口之间的相关程度均大于或等于预设相关程度值；若一组天线端口相干类型为部分相干，则表示该组天线端口中的部分天线端口之间的相干性满足预设相干条件，例如该组天线端口中的部分天线端口之间的相关程度均大于或等于预设相关程度值；若一组天线端口相干类型为非相干，则表示该组天线端口中的所有天线端口之间的相干性不满足预设相干条件，例如该组天线端口中的所有天线端口之间的相关程度均小于预设相关程度值。
可选地，上述两组天线端口相干类型可以包括以下任一项：
{完全相干，完全相干}；
{部分相干，部分相干}；
{非相干，非相干}；
{全部相干、部分相干和非相干，全部相干、部分相干、非相干}；
{部分相干和非相干，部分相干和非相干}；
{全部相干和部分相干、非相干，部分相干和非相干}；
{部分相干和非相干，全相干、部分相干和非相干}。
二、终端能力信息中至少包括满功率传输能力信息
可选地，上述满功率传输能力信息可以包括以下至少一项：SRS资源配置的天线端口数量的候选集合、支持终端满功率传输的预编码矩阵组。
需要说明的是，本申请实施例中，终端中的每个天线/天线端口对应的功率放大装置可能是非理想的。当终端中的每个天线/天线端口对应的功率放大装置可能是非理想的时，终端可以认为多个天线端口同时发送时，可以达到终端的满功率。从而终端可以上报多个支持低于该满功率的天线端口同时发射的预编码矩阵，以表明终端将上行数据预编码并采用这些天线端口的达到最大发射功率同时发送，可以使得终端的总发射功率达到终端的满功率，即可以实现满功率发送。
具体而言，终端采用候选集合中每个数量的天线端口同时发射/传输时，终端均可以实现满功率传输。终端采用支持终端满功率传输的预编码矩阵组中的每个预编码矩阵中的非零发射功率对应的天线端口同时发送/传输时，终端均可以实现满功率传输。
需要说明的是，本申请实施例中的预编码矩阵的每行均对应终端的一个天线端口。
可选地，本申请实施例中，上述候选集合中包括多个天线端口数量，终端上报包括该候选集合的终端能力信息之后，网络侧设备可以基于该候选集合中的至少部分天线端口数量为终端的SRS资源配置天线端口。
可选地，本申请实施例中，上述候选集合包括以下a至h中的至少一项：
a，{1，6}；
b，{1，2，6}；
c，{1，4，6}；
d，{1，2，4，6}；
e，{1，8}；
f，{1，2，8}；
g，{1，4，8}；
h，{1，2，4，8}。
可选的，对于支持6天线传输的终端来说，可以上报a，b，c，d中的任一项；对于支持8天线传输的终端来说可以上报e，f，g，h中的任何一项。
可选地，本申请实施例中，终端包括多个SRS资源，网络侧设备为每个SRS资源配置的天线端口数量可以为候选集合中一个数量。
网络侧设备可以为不同SRS资源配置候选集合中不同数量的天线端口；或者，网络设备可以为不同SRS资源配置候选集合中相同数量的天线端口，具体可以根据实际使用需求确定。
例如，当网络侧给终端配置了两个SRS资源，一个SRS资源配置8个天线端口，另外一个SRS资源配置为4个天线端口。若终端的8个天线端口采用非相干预编码不能达到满功率发送，则当网络侧设备指示了调度该4个天线端口的SRS资源来传输PUSCH时，终端可以通过天线虚拟化等技术，对终端的8根天线(例如8个天线的天线端口)进行虚拟化，例如两根天线对应一个SRS资源(即采用2个天线端口同时发送一个SRS资源)，来实现满功率发送。
又例如，假设候选集合包括上述的b：{1，2，6}，那么：若终端包括2个SRS资源，分别为SRS资源1、SRS资源2，则：
1)、网络侧设备可以为SRS资源1配置1个天线端口，且为SRS资源2配置2个天线端口；即不同SRS资源配置候选集合中不同数量的天线端口。或者，
2)、网络侧设备可以为SRS资源1配置2个天线端口，且为SRS资源2配置2个天线端口，即不同SRS资源配置候选集合中相同数量的天线端口。
可选地，本申请实施例中，网络侧设备可以为不同SRS资源配置相同的天线端口或不同的天线端口。
可以理解，本申请实施例中，对于支持终端满功率传输的预编码矩阵，终端采用该预编码矩阵对上行数据进行预编码，并将预编码后的上行数据映射到网络侧配置的上行信道(例如PUSCH)资源上进行传输时，该预编码后的上行数据的传输功率可以达到满功率。
可选地，本申请实施例中，上述支持终端满功率传输的预编码矩阵组可以包括以下至少一项：
i)第一预编码矩阵组，第一预编码矩阵组可以包括：在终端支持6天线传输、且支持2个天线端口为一组相干天线端口时采用的预编码矩阵，第一预编码矩阵组中的预编码矩阵满足：非零发射功率对应的天线端口相同。
可选地，本申请实施例中，第一预编码矩阵组中的预编码矩阵可以包括以下至少一项：
可选地，本申请实施例中，第一预编码矩阵组中的预编码矩阵可以包括以下至少一项：
可选地，本申请实施例中，第一预编码矩阵组中的预编码矩阵可以包括以下至少一项：
需要说明的是，上述支持终端满功率传输的预编码矩阵组中可以包括一个或多个第一预编码矩阵组。
ii)第二预编码矩阵组，第二预编码矩阵组可以包括：在终端支持6天线传输、且支持4个天线端口为一组相 干天线端口时采用的预编码矩阵，第二预编码矩阵组中的预编码矩阵满足：非零发射功率对应的天线端口相同。

iii)第三预编码矩阵组，第三预编码矩阵组包括：在终端支持8天线传输、且支持2个天线端口为一组相干天线端口时采用的预编码矩阵，第三预编码矩阵组中的预编码矩阵满足：非零发射功率对应的天线端口相同。
可选地，本申请实施例中，第三预编码矩阵组中的预编码矩阵可以包括以下至少一项：
可选地，本申请实施例中，第三预编码矩阵组中的预编码矩阵可以包括以下至少一项：
可选地，本申请实施例中，第三预编码矩阵组中的预编码矩阵可以包括以下至少一项：
可选地，本申请实施例中，第三预编码矩阵组中的预编码矩阵可以包括以下至少一项：
需要说明的是，上述支持终端满功率传输的预编码矩阵组中可以包括一个或多个第一预编码矩阵组。
iiii)第四预编码矩阵组，第四预编码矩阵组包括：在终端支持8天线传输、且支持4个天线端口为一组相干天线端口时采用的预编码矩阵，第四预编码矩阵组中的预编码矩阵满足：非零发射功率对应的天线端口相同。
需要说明的是，第四预编码矩阵组的数量可以为一个，也可以为多个。
可选地，本申请实施例中，第四预编码矩阵组中的预编码矩阵可以包括以下至少一项：
可选地，本申请实施例中，第四预编码矩阵组中的预编码矩阵可以包括以下至少一项：
可选地，本申请实施例中，第四预编码矩阵组中的预编码矩阵可以包括以下至少一项：
需要说明的是，本申请实施例提到的每个预编码矩阵都可以乘以一个归一化系数。
可以理解，本申请实施例中，终端支持6天线传输，上述预编码矩阵组可以包括上述i和ii中至少一项；终端支持8天线传输，上述预编码矩阵组可以包括上述iii和iiii中至少一项。
下面结合具体示例对本申请实施例提供的能力上报方法进行示例性地说明。
示例性地，对于支持8天线传输地终端，每个天线对应的功率放大装置可能是非理想的，例如，每个天线对应的输出功率最大是20dBm，而终端的满功率发送是23dBm,这种情况下，终端认为两个天线端口同时发送时可以达到23dBm,从而可以上报两个支持20dBm发送功率的天线端口都同时发射的预编码矩阵：例如下述的矩阵1和矩阵2。
其中，矩阵1中一列元素中每个元素对应一个天线端口，从矩阵1可以看出，第1个天线端口和第5个天线端口对应的元素的模为1，说明终端采用矩阵1对上行数据进行预编码后，这两个天线端口均是达到最大发射功率即20dBm，且同时发送，这种情况下总功率达到23dBm，即实现了满功率发送。
矩阵2为两流矩阵，每一列对应一个流(即数据流)，矩阵2在第一列的第一个元素非零，表示第一流数据通过第1个天线端口发送，矩阵2的第二列的第五个元素非零，表示第二流数据通过第五个天线端口发送，这样两流数据的发射功率之和也能达到满功率。
可以理解，矩阵1和矩阵2中非零发射功率的天线端口是相同的，均为第1个天线端口和第5个天线端口。
矩阵1：矩阵2：
又示例性地，对于支持8天线传输的终端，终端能够实现4个天线端口相干，且4个天线端口同时发送上行数据才能达到满功率传输，终端会上报4个天线同时发送的预编码矩阵：例如下述的矩阵1和矩阵2。
其中，从矩阵3可以看出，终端的第1个、第2个、第4个和第5个天线端口对应的预编码元素非零，表示这四个天线端口同时发送时，发射功率之和能达到满功率。
矩阵4为一个4流矩阵，每列对应一个流，从矩阵4可以看出，终端的天线端口之间非相干，且能够同个4个天线端口发送4流数据来实现同时发送，达到满功率。
矩阵3：矩阵4：
三、终端能力信息中至少包括天线端口与PT-RS端口间的关联关系信息

可选地，本申请实施例中，第一天线端口组和第二天线端口组可以为以下任一项：相干天线端口组、非相干天线端口组。
可选地，本申请实施例中，第一PT-RS端口和第二PT-RS端口可以为PT-RS端口(port)0或PT-RS端口1，且第一PT-RS端口与第二PT-RS端口不同。
下面对本申请实施例提供的能力信息上报方法进行示例性地说明。
示例性地，假设终端包括8个天线端口，且该8个天线端口的天线端口标识分别为：1000、1001、1002、1003、1004、1005、1006和1007，第一天线端口组为：{1000，1001，1004，1005}，第二天线端口组{1002，1003，1006，1007}，那么：
第一天线端口组可以共享PT-RS port0，第二天线端口组可以共享PT-RS端口1；或者，第一天线端口组的子集可以共享PT-RS port0，第二天线端口组的子集可以共享PT-RS端口1。
又示例性地，假设终端包括6个天线端口，且该6个天线端口的天线端口标识分别为：1000、1001、1002、1003、1004和1005，第一天线端口组为：{1000，1003，1001，1004}，第二天线端口组{1002，1005}，那么：第一天线端口组可以共享PT-RS端口0，第二天线端口可以共享PT-RS端口1；或者，第一天线端口组的子集可以共享PT-RS端口0，第二天线端口组的子集可以共享PT-RS端口1。
可选地，本申请实施例中，上述终端能力信息可以包括多组能力信息，每组能力信息对应终端的一个目标对象。
可选地，本申请实施例中，目标对象可以包括以下至少一项：天线面板，传输配置指示(Transmission Configuration Indicator，TCI)状态、波束信息、SRS资源。

需要说明的是，本申请实施例中，每个信息项可以包括以下任一项：信息项1、信息项2、信息项3。
其中，信息项1对应上述天线相干能力信息，信息项2对应上述满功率传输能力信息，信息项3对应上述天线端口与PT-RS端口间的关联关系信息。
