本申请实施例中的终端设备102是用户侧的一种用于接收或发射信号的实体，如手机。终端设备也可以称为终端设备(terminal)、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端设备(mobile terminal，MT)等。终端设备可以是具备通信功能的汽车、智能汽车、手机(mobile phone)、穿戴式设备、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)中的无线终端设备、无人驾驶(self-driving)中的无线终端设备、远程手术(remote medical surgery)中的无线终端设备、智能电网(smart grid)中的无线终端设备、运输安全(transportation safety)中的无线终端设备、智慧城市(smart city)中的无线终端设备、智慧家庭(smart home)中的无线终端设备等等。本申请的实施例对终端设备所采用的具体技术和具体设备形态不做限定。
在无线通信中，物理上行共享信道(Physical Uplink Shared Channel，PUSCH)的多天线预编码支持两种不同的模式配置，一种是基于码本的传输，一种是基于非码本的传输。NR中基于码本的PUSCH传输中，终端需要配置最多一个SRS资源集合用于基于码本的上行传输，SRS资源集可配置多个SRS资源，网络侧会指示终端对应该SRS资源集合的SRS资源指示信号SRI(Sounding Resource Indicator，SRI)，通过SRI指示选择SRS资源，同样基站基于上行CSI的测量最后由网络决定终端实际传输使用的预编码矩阵TPMI和传输层数RI并通知终端。终端在接下来的上行传输中的数据需要使用网络侧指定的PMI和RI进行预编码，同时对于预编码后的数据按照SRI指示的SRS资源对应的空间滤波器SpatialRelationInfo映射到相应的天线端口上。不同的SRS对应不同的空间滤波器，因此终端经过预编码的数据需要经过SRI指示的SRS所使用的空间滤波器进行滤波。通过这种方式可以支持上行数据从单层到满秩的传输，在目前版本的NR系统中，上行最大支持到4层的数据传输。

表5为采用4天线端口单层传输所使用的码字，预编码信息TPMI和传输层数(rankindication，RI)，本表格针对使用CP-OFDM波形的情况，不使能DFTs-OFDM预编码且传输层数RI为1层的情况。本表格中W为矩阵，按TPMI指数的递增顺序从左到右排序，矩阵中j为负数，每个矩阵前乘的1/2为 矩阵的归一化系数。
传输层数等于信道矩阵的秩，即能够独立并行传输的数据流。层数是通过RI来进行秩指示，由终端设备告知网络侧设备能够支持的最大上行PUSCH传输层数。支持的RI受限于发送天线数，如果发送天线最多为两天线，那么秩的最大值为2。
不是所有的终端都可以将各天线端口校准至可以相干传输，因此上行传输的码本设计需要考虑终端的天线相干传输能力。

下面结合附图对本申请所提供的支持8Tx的基于码本的PUSCH传输的预编码指示方法及其装置进行详细地介绍。
请参见图2，图2是本申请实施例提供的一种支持8Tx的基于码本的PUSCH传输的预编码指示方法的流程示意图。所述方法由网络侧设备执行。如图2所示，该方法可以包括但不限于如下步骤：
步骤S201：确定用于终端设备的至少一个功能同为“码本”的探测参考信号SRS资源集合，其中，每个所述SRS资源集合包括多个SRS资源，且所述多个SRS资源构成用于上行信道探测的对应8个SRS天线端口的SRS资源组。
本申请实施例中，终端设备进行的PUSCH传输为基于码本的上行传输，网络侧设备可以为终端配置多个SRS资源供终端设备选择。终端根据网络侧设备发送的SRS资源的配置信息，进行相应的SRS的发送。网络侧设备根据接收到的SRS，向终端设备发送SRI、TPMI和传输秩指示(Transmitted Rank Indication，TRI)信息。根据SRI，终端可以确定基站选择的SRS资源，从而确定上行传输使用与该SRS资源对应的SRS传输相同的天线和天线端口，即对应的空间滤波(模拟波束)。通过对应于该SRI的SRS资源的TPMI和TRI信息，终端可以进一步确定出上行PUSCH传输的预编码和传输层数。
为了支持基于码本的8层PUSCH传输，网络侧设备为终端设备确定至少一个功能同为“码本”的探测参考信号SRS资源集合，在这种配置下，终端设备在选取传输PUSCH所用的资源时，可以选择从多个对应8端口的SRS资源组中进行选择，并且不同的SRS资源组对应终端发送的不同的空间滤波。不同的SR资源组可以配置不同资源类型，一个SRS资源组对应一个SRS资源集合，其中所包含的SRS资源类型应该相同，具体可以是周期的SRS资源，半持续的SRS资源，或者非周期的SRS资源，，用于适配不同的基站调度需求。
步骤S202：向所述终端设备发送SRS资源指示SRI，其中，所述SRI用于指示所述至少一个SRS资源集合之中的一个SRS资源集合用于PUSCH发送所使用的空间滤波。
本申请实施例中，基于码本的PUSCH传输中，网络侧设备需要配置多个SRS资源集合用于基于码本的上行传输，每个SRS资源集合可配置多个SRS资源。然后网络侧设备会向终端设备反馈SRI，通过SRI指示选择的SRS资源集合。终端在接下来的上行传输中的数据需要使用网络侧指定的PMI和RI进行预编码，同时对于预编码后的数据按照SRI指示的SRS资源集合对应的空间滤波器SpatialRelationInfo映射到相应的天线端口上。不同的SRS资源集合会使用不同的空间滤波器传输，因此终端经过预编码的数据需要经过SRI指示的SRS资源集合所使用的空间滤波器进行滤波。
通过实施本申请实施例，可以通过网络侧设备确定至少一个功能同为“码本”的探测参考信号SRS资源集合，并通过SRI指示终端设备进行PUSCH发送使用的包含多个SRS资源的SRS资源组，用于实现8个SRS端口情况下对基于码本的PUSCH发送的支持，通过使用现有的SRS资源组合来实现8端口SRS功能，避免了重新定义新的8端口SRI映射表，降低了标准化工作的难度和工作量。
请参见图3，图3是本申请实施例提供的一种支持8Tx的基于码本的PUSCH传输的预编码指示方法的流程示意图。所述方法由网络侧设备执行。如图3所示，该方法可以包括但不限于如下步骤：
步骤S301：获取所述终端设备发送的所述终端设备的能力信息，其中，根据所述终端设备的能力信息确定所述至少一个SRS资源集合。
本申请实施例中，终端设备通过向网络侧设备上报所述终端设备的能力信息，来供网络侧设备参考，以为终端设备配置符合终端设备能力信息的SRS资源集合。
可选的，所述终端设备的能力信息为终端设备中天线进行相干传输的能力，包括全相干、部分相干或非相干。
本申请实施例中，定义了三种终端设备的天线相干传输能力：
全相干(Full Coherent)：终端所有的天线都可以相干传输；
部分相干(Partial coherent)：终端同一相干传输对内的天线可以相干传输，相干传输对之间不能相干传输。
非相干(Non-coherent)：终端没有天线可以进行相干传输。
可选的，所述多个SRS资源之中包括以下之中的一项或多项：
单端口SRS资源；
2端口SRS资源；
4端口SRS资源。
本申请实施例中，现有的SRS资源定义包括以上三种端口数量，通过对包含不同端口数量的SRS资源进行组合，以组成8端口的SRS资源来支持终端8Tx基于码本的PUSCH传输。避免了重新定义8端口SRS，可以更为灵活的配置SRS资源。
可选的，所述多个SRS资源包括以下之中的任一项：
两个4端口SRS资源构成的组合；
一个4端口SRS资源和两个2端口SRS资源构成的组合；
四个2端口SRS资源构成的组合；
八个单端口SRS资源构成的组合。
本申请实施例中，对于构成8端口SRS的可能SRS资源组合，包括：
组合1：1个4端口SRS资源+1个4端口SRS资源；
组合2：1个4端口SRS资源+1个2端口SRS资源+1个2端口SRS资源；
组合3：1个2端口SRS资源+1个2端口SRS资源+1个2端口SRS资源+1个2端口SRS资源；
组合4：8个单端口的SRS资源组合。
通过以上组合可以利用现有的SRS资源类型组合以构成8端口的SRS。
在一种可能的实施例中，终端设备中的天线为全相干的，那么可以配置任意SRS资源组合。
在一种可能的实施例中，终端设备中的天线不是都为全相干的包括2几种情况：
如果8天线中每4个天线为相干天线分组，2组天线之间为非相干的情况，则对应部分相关的天线配置，则可以对应优先配置为2个4端口SRS资源用于构成一个8端口SRS资源组；
同理，如果每2个天线为相关天线分组，且4个天线组之间为非相干的情况，每个天线组内是相干的，则同样对应部分相关的天线配置，则可以配置为4个2端口的SRS资源用于构成一个8端口SRS资源组。
请参见图4，图4是本申请实施例提供的一种支持8Tx的基于码本的PUSCH传输的预编码指示方法的流程示意图。所述方法由网络侧设备执行。如图4所示，该方法可以包括但不限于如下步骤：
步骤S401：向所述终端设备发送SRI表格，其中，所述SRI表格之中包括SRI与所述SRS资源集合的对应关系，且所述SRI的SRI指示域的比特数由N SRS决定，其中，所述N SRS为对应配置给所述终端设备的SRS资源集合数目。
本申请实施例中网络侧设备通过SRI指示的时候可以直接指示对应配置下的SRI表格里的索引，终端通过查表得到对应指示的是哪一个SRS资源集合。
在一种可能的实施例中，网络侧设备为终端设备配置了两个SRS资源集合，即N SRS＝2，其中的第一SRS资源集合中SRS资源组合的类型为组合1，其中包含两个4端口SRS资源；第二SRS资源集合中SRS资源组合的类型为组合2，其中包含1个4端口SRS资源和两个2端口SRS资源。那么网络侧设备需要通过两个SRI来为终端设备配置这两个SRS资源集合，由于对应到所述SRI的SRI指示域的比特数由N SRS决定，所以终端设备可以根据这两个SRI查找N SRS＝2对应的SRI表格，即上述表1。SRI表格-为预定义的表格，其中包括SRI索引与所述SRS资源集合中的SRS资源的对应关系，在本实施例中，SRI索引为0时对应第一SRS资源集合中配置的SRS资源组，SRI索引为1时对应第二SRS资源集合中配置的SRS资源组。

可选的，所述SRI指示域的比特数由N SRS决定，其中，所述N SRS为对应配置给所述终端设备的SRS 资源集合数目。
可选的，所述多个SRS参考信号集合配置为以下之中的任意一种：

在一种可能的实施例中，网络侧设备为终端设备配置了三个SRS资源集合，即N SRS＝3，其中的第一SRS资源集合中SRS资源组合的类型为组合1，其中包含两个4端口SRS资源；第二SRS资源集合中SRS资源组合的类型为组合2，其中包含1个4端口SRS资源和两个2端口SRS资源；第三SRS资源集合中SRS资源组合的类型为组合3，其中包含4个2端口SRS资源。那么网络侧设备需要通过三个SRI来为终端设备配置这两个SRS资源集合，由于对应到所述SRI的SRI指示域的比特数由N SRS决定，所以终端设备可以根据这三个SRI查找N SRS＝3对应的SRI表格，即上述表2。SRI表格为预定义的表格，其中包括SRI索引与所述SRS资源集合中的SRS资源的对应关系，在本实施例中，SRI索引为0时对应第一SRS资源集合中配置的SRS资源组，SRI索引为1时对应第二SRS资源集合中配置的SRS资源组，SRI索引为2时对应第三SRS资源集合中配置的SRS资源组。
在一种可能的实施例中，网络侧设备为终端设备配置了两个SRS资源集合，即N SRS＝2，其中的第一SRS资源集合中SRS资源组合的类型为组合3，其中包含四个2端口SRS资源；第二SRS资源集合中SRS资源组合的类型为组合4，其中包含8个单端口SRS资源。那么网络侧设备需要通过两个SRI来为终端设备配置这两个SRS资源集合，网络侧设备对第一SRS资源集合和第二SRS资源集合分别进行编号，所述编号即为所述位图信息。终端设备在接收到所述位图信息后，根据自身天线的相干传输能力和位图信息在预先配置好的表格中查找对应的TPMI和RI，如果所述终端设备有4天线端口，且传输层数为1，所述表格即为上述表4，表4为4天线端口的终端设备对应的TPMI和RI，如果为终端设备中的天线都可以相干传输，即天线全相干，且针对第一SRS资源集合分配给终端设备的位图信息为0，则在表4中对应的TPMI＝0，然后在对应的4天线单层传输的码本(也即上述表5)中查询TPMI＝0对应的SRS资源，即可获取网络侧设备为终端设备配置的第一SRS资源集合中的各个SRS资源。
请参见图6，图6是本申请实施例提供的一种支持8Tx的基于码本的PUSCH传输的预编码指示方法的流程示意图。所述方法由终端设备执行。如图6所示，该方法可以包括但不限于如下步骤：

本申请实施例中，基于码本的PUSCH传输中，网络侧设备需要配置多个SRS资源集合用于基于码本的上行传输，每个SRS资源集合可配置多个SRS资源。然后网络侧设备会向终端设备反馈SRI，通过SRI指示选择的SRS资源集合。终端在接下来的上行传输中的数据需要使用网络侧指定的PMI和RI进行预编码，同时对于预编码后的数据按照SRI指示的SRS资源集合对应的空间滤波器Spatial Filter映射到相应的天线端口上。不同的SRS资源集合会使用不同的空间滤波器传输，因此终端经过预编码的数据需要经过SRI指示的SRS资源集合所使用的空间滤波器进行滤波。
通过实施本申请实施例，可以通过网络侧设备确定至少一个功能同为“码本”的探测参考信号SRS资源集合，并通过SRI指示终端设备进行PUSCH发送使用的包含多个SRS资源的SRS资源组，用于实现8个SRS端口情况下对基于码本的PUSCH发送的支持，通过使用现有的SRS资源组合来实现8端口SRS功能，避免了重新定义新的8端口SRI映射表，降低了标准化工作的难度和工作量。
