多点协作传输技术大致可分为相干传输(Coherent Joint Transmission，CJT)和非相干传输(InCoherent Joint Transmission，NCJT)两种。所谓CJT是指每个数据流会通过加权向量映射到参与协作的m-TRP/Panel上。CJT相当于把多个子阵拼接称为一个更高维度的虚拟阵列，以获得更高的赋形或预编码增益。
图1给出了三个TRPs通过CJT为UE服务的场景，UE到各TRP的信道分别表示为H 1、H 2和H 3。在计算该UE的预编码可以把这个信道组合在一块视为一个更高维度的信道即

为了更好的理解本申请实施例公开的一种TRP或TRP组的相位因子和幅度因子发送/接收方法，下面首先对本申请实施例适用的通信系统进行描述。
请参见图1a，图1a为本申请实施例提供的一种通信系统的架构示意图。该通信系统可包括但不限于一个网络设备和一个终端设备，图1a所示的设备数量和形态仅用于举例并不构成对本申请实施例的限定，实际应用中可以包括两个或两个以上的网络设备，两个或两个以上的终端设备。图1a所示的通信系统以包括一个网络设备101和一个终端设备102为例。
需要说明的是，本申请实施例的技术方案可以应用于各种通信系统。例如：长期演进(long term evolution，LTE)系统、第五代(5th generation，5G)移动通信系统、5G新空口(new radio，NR)系统，或者其他未来的新型移动通信系统等。还需要说明的是，本申请实施例中的侧链路还可以称为侧行链路或直通链路。

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。
