Description

一种多点协作传输方法、装置及存储介质 技术领域
本公开涉及通信技术领域，尤其涉及一种多点协作传输方法、装置及存储介质。
背景技术
随着通信技术的发展，为了改善边缘覆盖，为服务区内各用户提供均衡的服务质量，例如，改善小区边缘用户的信号接收强度，提高边缘用户体验，并提高系统频谱效率。当网络设备(例如基站)有多个传输接收点(Transmission Reception Point，TRP)时，可以使用多个TRP(Muplti-TRP,mTRP)/多面板(PANEL)为终端提供服务。并且，为了在服务区内提供更为均衡的服务质量，引入多点协作传输(Coordinated Multiple Point transmission，CoMP)技术。
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(Non-Coherent 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相当于将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。
相关技术中，针对非相干传输，支持网络设备为终端配置多个TRP以及相关的SRS资源，终端基于网络设备配置的TRP以及SRS资源选择相应的SRS资源进行多点协作传输。但是对于相干传输，目前对于网络设备如何配置TRP以及终端如何就那些TRP的选择上报，还没有明确方案。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。
本公开实施例预编码指示方法可以应用于图1所示的无线通信系统中。参阅图1所示，该无线通信系统中包括网络设备和终端。终端通过无线资源与网络设备相连接，并进行数据传输。
可以理解的是，图1所示的无线通信系统仅是进行示意性说明，无线通信系统中还可以包括其他网络设备，例如还可以包括核心网设备、无线中继设备和无线回传设备等，在图1中未画出。本公开实施例对该无线通信系统中包括网络设备数量和终端数量不做限定。
进一步可以理解的是，本公开实施例无线通信系统，是一种提供无线通信功能的网络。无线通信系统可以采用不同的通信技术，例如码分多址(code division multiple access,CDMA)、宽带码分多址(wideband code division multiple access，WCDMA)、时分多址(time division multiple access，TDMA)、频分多址(frequency division multiple access，FDMA)、正交频分多址(orthogonal frequency-division multiple access，OFDMA)、单载波频分多址(single Carrier FDMA，SC-FDMA)、载波侦听多路访问/冲突避免(Carrier Sense Multiple Access with Collision Avoidance)。根据不同网络的容量、速率、时延等因素可以将网络分为2G(英文：generation)网络、3G网络、4G网络或者未来演进网络，如5G网络，5G网络也可称为是新无线网络(New Radio，NR)。为了方便描述，本公开有时会将无线通信网络简称为网络。
进一步的，本公开中涉及的网络设备也可以称为无线接入网设备。该无线接入网设备可以是：基站、演进型基站(evolved node B，基站)、家庭基站、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 point，TP)或者发送接收点(transmission and reception point，TRP)等，还可以为NR系统中的gNB，或者，还可以是构成基站的组件或一部分设备等。应理解，本公开的实施例中，对网络设备所采用的具体技术和具体设备形态不做限定。在本公开中，网络设备可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域(小区)内的终端进行通信。此外，当为车联网(V2X)通信系统时，网络设备还可以是车载设备。
进一步的，本公开中涉及的终端，也可以称为终端设备、用户设备(User Equipment，UE)、移动台(Mobile Station，MS)、移动终端(Mobile Terminal，MT)等，是一种向用 户提供语音和/或数据连通性的设备，例如，终端可以是具有无线连接功能的手持式设备、车载设备等。目前，一些终端的举例为：智能手机(Mobile Phone)、客户前置设备(Customer Premise Equipment，CPE)，口袋计算机(Pocket Personal Computer，PPC)、掌上电脑、个人数字助理(Personal Digital Assistant，PDA)、笔记本电脑、平板电脑、可穿戴设备、或者车载设备等。此外，当为车联网(V2X)通信系统时，终端设备还可以是车载设备。应理解，本公开实施例对终端所采用的具体技术和具体设备形态不做限定。
相关技术中，网络设备(例如基站)有多个TRP时，能够使用M-TRP/多面板为终端提供服务，且引入CoMP技术，以实现网络设备能够在服务区内提供更为均衡的服务质量。
不同于单点传输如单个TRP或面板(Pannel)，多点协作传输是指多个TRP(Muplti-TRP,mTRP)/panel为一个用户提供数据服务。其中，每个TRP的天线阵可以被分为若干相对独立的天线面板，因此整个阵面的形态和端口数都可以随部署场景与业务需求进行灵活的调整。而天线面板或TRP之间也可以由光纤连接，进行更为灵活的分布式部署。在毫米波波段，随着波长的减小，人体或车辆等障碍物所产生的阻挡效应将更为显著。在这种情况下，从保障链路连接鲁棒性的角度出发，可以利用多个TRP或面板之间的协作，从多个角度的多个波束进行传输/接收，从而降低阻挡效应带来的不利影响。
根据发送信号流到多个TRP/panel上的映射关系，多点协作传输技术可以分为相干传输(Coherent Joint Transmission，CJT)和非相干传输(Non-Coherent Joint Transmission，NCJT)两种。其中，相干传输时，每个数据流会通过加权向量映射到参与协作的多个TRP/panel之上。而非相干传输时，每个数据流只映射到部分的TRP/panel上。其中，相干传输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2示出了本公开一示例性实施例中多个TRP通过相干传输为终端服务的场景示意图。图2中，以三个TRPs通过相干传输为终端提供数据服务的场景为例进行说明，但并不引以为限。图2中，终端到各TRP的信道分别表示为H 1、H 2和H 3。在计算终端的下行数据传输预编码时，可以将各TRP映射的信道组合在一块，视为一个更高维度的信道。即
Figure PCTCN2022112120-appb-000001
然后根据组合后的信道H计算终端的下行数据传输预编码。
相关技术中，支持调度终端从多个panel面向多个TRP基于码本的下行数据传输。
其中，多个TRP进行相干传输时可以采用以下可选的码本结构用于计算用户的下行数据传输预编码。

其中，相干传输对于传输点之间的同步以及回程链路的传输能力有着更高的要求，因而对现实部署条件中的很多非理想因素较为敏感。
本公开实施例提供一种多点协作传输方法，在该方法中，多个TRP或TRP组通过相干传输为终端提供数据服务时，通过网络设备配置执行相干协作传输的多个TRP或TRP组的多点协作传输配置信息，并由终端基于网络设备配置的多点协作传输配置信息，在网络设备配置的多个TRP或TRP组中选择部分或全部进行相干传输。终端将选择的用于相干传输的TRP或TRP组上报给网络设备，以便网络设备确定终端选择的用于相干传输的TRP或TRP组。
