Description

用于多发送接收节点的传输配置指示状态指示方法及装置、计算机可读存储介质
本申请要求2022年1月7日提交中国专利局、申请号为202210017817.4、发明名称为“用于多发送接收节点的传输配置指示状态指示方法及装置、计算机可读存储介质”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及通信技术领域，具体地涉及一种用于多发送接收节点的传输配置指示状态指示方法及装置、计算机可读存储介质。
背景技术
基于第三代合作伙伴计划(3rd Generation Partnership Project，简称3GPP)新空口(New Radio，简称NR，也可称为新无线)协议，基站和终端通过波束训练过程来确定最优的收发波束，从而利用最优收发波束来提升上下行信号的传输可靠性。在波束训练和上报过程中，终端会保存每个上报的发送波束对应的接收波束。在波束指示方面，基站向终端指示发送波束，终端根据指示的发送波束确定对应的接收波束。
在实际部署环境中，上下行数据信道、控制信道和部分参考信号通常采用相同方向的收发波束进行通信。因此，在NR系统协议17(Release 17，简称Rel-17)版本的标准化过程中，针对多输入多输出(Multiple-Input Multiple-Output，简称MIMO)技术进行进一步增强的方式之一是引入统一的波束配置框架，实现统一指示上下行控制信道、数据信道和参考信号采用相同方向的收发波束。

具体实施方式
如背景技术所言，如何对波束指示方式进行增强，从而使得终端能够确定基站所指示的波束具体对应多TRP中哪一个TRP下的上下行控制信道、数据信道和参考信号，是目前协议亟需解决的问题。
为解决上述技术问题，在基站侧，本发明实施例提供一种用于多发送接收节点的传输配置指示状态指示方法，包括：发送配置信息，所述配置信息包括多个候选传输配置指示TCI状态；发送状态指示信息以指示目标TCI状态，所述目标TCI状态选取自所述多个候选TCI 状态，之前/同时，发送关联关系指示信息以至少指示所述目标TCI状态对应的发送接收节点TRP。
本实施方案提供一种适用于多TRP场景的波束指示方式，使得基站能够在波束指示过程中将对应的TRP也指示给终端，从而确保终端能够从多个TRP中合理确定正确的TRP进行数据传输。
为使本发明的上述目的、特征和有益效果能够更为明显易懂，下面结合附图对本发明的具体实施例做详细的说明。
图1是本发明实施例的第一种用于多发送接收节点的传输配置指示状态指示方法的流程图。
本实施方案可以应用于多TRP场景，如应用于支持多TRP传输的基站和终端之间的波束指示场景。在本实施方案中，可以通过传输配置指示(Transmission Configuration Indication，简称TCI)状态(简称TCI状态)指示波束，如指示数据传输时的发送波束。
在具体实施中，下述步骤S101～步骤S102所提供的传输配置指示状态指示方法可以由网络设备中的具有信息指示功能的芯片执行，也可以由网络设备中的基带芯片执行。例如，网络设备可以包括基站。
具体地，参考图1，本实施例所述用于多TRP的TCI状态指示方法可以包括如下步骤：
步骤S101，发送配置信息，所述配置信息包括多个候选传输配置指示TCI状态；
步骤S102，发送状态指示信息以指示目标TCI状态，所述目标TCI状态选取自所述多个候选TCI状态，之前/同时，发送关联关系指示信息以至少指示所述目标TCI状态对应的发送接收节点TRP。
进一步，多个候选TCI状态与多个TRP之间可以存在关联关系。例如，候选TCI状态与TRP可以是一一对应的。又例如，多个候选TCI状态可以对应同一TRP。
在一个具体实施中，步骤S102中，发送关联关系指示信息的动作可以是在发送状态指示信息之前执行的。例如，配置信息可以包括关联关系指示信息，从而基站可以在向终端配置多个候选TCI状态的同时一并指示对应的TRP。
具体地，关联关系指示信息可以包括：每一候选TCI状态与多个TRP之间的关联关系。
例如，关联关系指示信息可以包括每一候选TCI状态的标识与TRP索引之间的关联关系。
又例如，关联关系指示信息可以包括各候选TCI状态关联的物理小区标识(Physical Cell Identify，简称PCI)与服务小区的PCI的比较结果与多个TRP之间的关联关系。以多TRP的数量为两个(分别记作第一TRP和第二TRP)为例，关联关系指示信息中指示的内容可以例如是：若候选TCI状态中包含的参考信号(Reference Signal，简称RS)是同步信号块(Synchronization Signal/Physical Broadcast Channel Block，简称SS/PBCH BLOCK，也即，SSB)或者该参考信号的准共址(quasi co-located，简称QCL)源参考信号是SSB，且前述SSB关联的PCI与服务小区的PCI不同，则该候选TCI状态对应第一TRP；否则，该候选TCI状态对应第二TRP。其中，服务小区可以是预配置的，如终端接入基站后就可以获得服务小区的PCI。
在本具体实施中，通过配置信息中携带的关联关系指示信息，每一候选TCI状态都能关联到对应的TRP。
在一个具体实施中，步骤S102中，发送关联关系指示信息的动作可以是在发送状态指示信息之前执行的。例如，步骤S101之后，步骤S102之前，本具体实施还可以包括步骤：发送激活信息，所述激活信息包括一个或多个激活TCI状态，所述激活TCI状态选取自所述多个候选TCI状态，所述目标TCI状态选取自所述一个或多个激活TCI状态。
具体地，基站可以从配置给终端的所有候选TCI状态中挑选一个或多个候选TCI状态进行激活，终端需要跟踪这些激活TCI状态对应的波束的信号质量，并维护相应的接收波束。然后，基站会从所有激活TCI状态中实际激活一个用于实际的信号传输，该实际激活的激活TCI状态即为所述目标TCI状态。
进一步，所述激活信息还包括所述关联关系指示信息。所述关联关系指示信息可以包括一个或多个激活TCI状态与多个TRP的关联关系。
例如，关联关系指示信息可以包括每一激活TCI状态的标识与TRP索引之间的关联关系。
在本具体实施中，在激活配置给终端的一个或多个候选TCI状态的同时，基站可以将被激活的候选TCI状态对应的TRP指示给终端。由此，基站可以更灵活的进行TRP配置，例如，每次激活同一候选TCI状态时可以关联不同的TRP。
在一个具体实施中，步骤S102中，发送关联关系指示信息动作可以是在发送状态指示信息的同时一并执行的。例如，关联关系指示信息可以通过状态指示信息发送。
具体地，关联关系指示信息可以包括目标TCI状态对应的TRP。相应的，状态指示信息可以关联所述目标TCI状态对应的TRP。
例如，状态指示信息可以指示目标TCI状态的标识并通过物理下行控制信道(Physical Downlink Control Channel，简称PDCCH)承载，所述PDCCH还关联目标TCI状态对应的TRP索引。
由此，基站可以更灵活地进行TRP配置，如每次激活同一目标TCI状态时可以关联不同的TRP。进一步，基站在最终指示目标TCI状态时针对性地指示该TCI状态对应的TRP，使得终端在接收到状态指示信息后既能准确获知该目标TCI状态应用于对应TRP的上下行控制信道、数据信道和参考信号。
在一个具体实施中，在步骤S102之后，还可以执行步骤：目标TCI状态对应的TRP根据目标TCI状态发送上下行控制信道、数据信道和参考信号。具体地，目标TCI状态对应的TRP可以包括所述基站。
由上，在基站侧，本实施方案提供一种适用于多TRP场景的波束指示方式，使得基站能够在波束指示过程中将对应的TRP也指示给终端，从而确保终端能够从多个TRP中合理确定正确的TRP进行数据传输。

在第一个典型的应用场景中，参考图5，UE51和基站52可以分别执行上述图3和图1所示方法以进行多TRP场景下的波束指示。在本应用场景中，通过TCI状态指示波束，基站52即为最终激活的目标TCI状态对应的TRP，假设共支持两个TRP(分别记作第一TRP和第二TRP)。
具体地，参考图5，基站52可以执行操作s501，以向UE51配置多个候选TCI状态，并指示每一候选TCI状态关联的TRP。
例如，在操作s501中，基站52可以在发送给UE51的配置信息中直接携带每个候选TCI状态的标识和TRP索引之间的关联关系。
又例如，在操作s501中，基站52可以在发送给UE51的配置信息中指示，若候选TCI状态中包含的RS是SSB(或该RS的QCL源RS是SSB)，且该SSB关联的PCI不同于UE51的服务小区的PCI，则该候选TCI状态对应第一TRP；否则，该候选TCI状态对应第二TRP。
接下来，基站52可以执行操作s502，以向UE51激活之前配置的所述多个候选TCI状态中的一个或多个。也即，通过激活信息向UE51指示一个或多个激活TCI状态。
响应于接收到配置信息和激活信息，UE51可以执行操作s503，以根据前述基站52指示的关联关系确定各激活TCI状态对应的TRP。

例如，在操作s602中，基站62可以在发送给UE61的激活信息中直接携带每个激活TCI状态的标识和TRP索引之间的关联关系。
响应于接收到激活信息，UE61可以执行操作s603，以根据前述基站62指示的关联关系确定各激活TCI状态对应的TRP。
然后，基站62可以执行操作s604，以通过状态指示信息向UE61指示实际使用的目标TCI状态。
响应于接收到状态指示信息，UE61可以执行操作s605，以从之前执行操作s603的结果中确定目标TCI状态应用于对应TRP的上下行控制信道、数据信道和参考信号。
相应的，后续基站62可以根据目标TCI状态发送上下行控制信道、数据信道和参考信号，而UE61同样可以接收目标TCI状态对应的TRP发送的上下行控制信道、数据信道和参考信号。
在一个变化例中，操作s603可以被省略，也就是说，UE61可以仅在接收到目标TCI状态后，再根据操作s602获取的关联关系确定目标TCI状态对应的TRP。
在第三个典型的应用场景中，参考图7，UE71和基站72可以分别执行上述图3和图1所示方法以进行多TRP场景下的波束指示。在本应用场景中，通过TCI状态指示波束，基站72即为最终激活的目标TCI状态对应的TRP。
具体地，参考图7，基站72可以执行操作s701，以向UE71配置多个候选TCI状态。
接下来，基站72可以执行操作s702，以向UE71激活之前配置的所述多个候选TCI状态中的一个或多个。
然后，基站72可以执行操作s703，以通过状态指示信息向UE71指示实际使用的目标TCI状态，并指示目标TCI状态对应的TPR。
例如，在操作s703中，基站72可以将发送给UE71的状态指示信息关联TRP索引以实现关联关系的指示。
响应于接收到状态指示信息，UE51可以执行操作s704，以根据状态指示信息确定目标TCI状态应用于对应TRP的上下行控制信道、数据信道和参考信号。
相应的，后续基站72可以根据目标TCI状态发送上下行控制信道、数据信道和参考信号，而UE71同样可以接收目标TCI状态对应的TRP发送的上下行控制信道、数据信道和参考信号。
