具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
可以理解，本申请所使用的术语“第一”、“第二”等可在本文中用于描述各种概念，但除非特别说明，这些概念不受这些术语限制。这些术语仅用于将一个概念与另一个概念区分。
首先，对本申请实施例中涉及的名词进行简单介绍：
下行波束管理：在NR(New Radio，新空口)中，网络设备可以采用模拟波束来传输PDSCH(Physical Downlink Shared Channel，物理下行共享信道)。在进行模拟波束赋形之前，网络设备需要通过下行波束管理过程来确定所用的波束，下行波束管理可以基于CSI-RS(Channel State Information Reference signal，信道状态信息参考信号)或者SSB进行。
在一种可能实现方式中，网络设备发送用于波束管理的多个SSB或者多个CSI-RS资源，终端基于这些SSB或CSI-RS资源进行测量，选择接收质量最好的预设数量的SSB或者CSI-RS资源，并将该预设数量的SSB索引或CSI-RS资源索引以及对应的RSRP(Reference Signal Receiving Power，参考信号接收功率)上报给网络设备。
其中，SSB为服务小区的SSB，终端需要基于网络设备配置的SSB索引集合进行服务小区SSB的测量和上报。网络设备根据终端的上报得到一个最优的SSB或CSI-RS资源，将其所用的发送波束确定为下行传输所用的发送波束，从而采用该发送波束传输下行控制信道或者数据信道。网络设备在传输下行控制信道或数据信道之前，会通过TCI(Transmission Configuration indication，传输配置指示)状态将对应的QCL(Quasi Co location，准共址)参考信号指示给终端，从而终端可以采用之前接收该QCL参考信号所用的接收波束，来接收对应的下行控制信道或数据信道。下面以SSB为例对下行波束管理进行说明，则基于SSB的波束管理过程如图1所示，网络设备向终端发送N个SSB，终端根据接收SSB的质量选择资源，向网络设备发送SSB索引信息或接收功率，网络设备向终端发送TCI状态，再通过TCI状态对应的QCL的发送波束发送PDCCH(Physical Downlink Control Channel，物理下行控制信道)、 PDSCH或CSI-RS。
下行传输的QCL指示：在NR系统中，网络设备可以为每个下行参考信号或下行信道配置对应的TCI状态，用于指示目标下行参考信号或目标下行信道对应的QCL参考信号，从而终端基于该QCL参考信号进行目标下行参考信号或目标下行信道的接收。
其中，一个TCI状态可以包含如下配置：
TCI状态标识，用于指示一个TCI状态；
QCL信息1；
QCL信息2。
其中，一个QCL信息包括：
QCL类型配置信息，可以是QCL type A，QCL typeB，QCL typeC或QCL typeD中的任一个；
QCL参考信号配置信息，包括参考信号所在的小区标识，BWP(Band Width Part，带宽部分)标识以及参考信号的标识。其中，参考信号的标识可以为CSI-RS资源标识或SSB索引。
其中，QCL信息1和QCL信息2中，至少一个QCL信息的QCL类型必须为typeA，typeB，typeC中的一个，另一个QCL信息的QCL类型必须为QCL type D。
其中，不同QCL类型配置的定义如下：
“QCL-TypeA”':{多普勒频移，多普勒扩展，平均延迟，延迟扩展}；
“QCL-TypeB”:{多普勒频移，多普勒扩展}；
“QCL-TypeC”:{多普勒频移，平均延迟}；
“QCL-TypeD”:{空间接收参数}。
如果网络设备通过TCI状态配置目标下行信号的QCL参考信号为SSB或CSI-RS资源，且QCL类型配置为typeA，typeB或typeC，则终端可以假设目标下行信号与SSB或CSI-RS资源的目标大尺度参数是相同的，从而采用相同的接收参数进行接收，目标大尺度参数通过QCL类型配置来确定。另外，如果网络设备通过TCI状态配置目标下行信号的QCL参考信号为SSB或CSI-RS资源，且QCL类型配置为typeD，则终端可以采用与接收SSB或CSI-RS资源相同的接收波束，来接收目标下行信号，即此时终端可以根据TCI状态来确定目标下行信号的接收波束。
其中，目标下行信号与对应的QCL参考信号在网络设备中由同一个TRP或者同一个panel或者相同的波束来发送。如果两个下行信号的传输TRP或传输panel或发送波束不同，网络设备会配置不同的TCI状态。
对于下行控制信道，TCI状态可以采用RRC信令或者RRC信令和MAC信令的方式来指示。对于下行数据信道，可用的TCI状态集合通过RRC信令来指示，并通过MAC层信令来激活其中部分TCI状态，通过DCI中的TCI状态指示域从激活的TCI状态中指示一个或两个TCI状态，该一个或两个TCI状态用于DCI调度PDSCH。对于CSI-RS，可以通过高层信令直接配置CSI-RS的QCL参考信号，该信号可以是一个SSB或者另一个CSI-RS。
上行波束管理：在NR中，对于每个PUCCH资源，在RRC信令中配置多个空间相关信息(PUCCH-spatialrelationinfo)，再通过MAC层信令从中指示当前所用的PUCCH-spatialrelationinfo。其中，每个PUCCH-spatialrelationinfo中包含一个用于确定PUCCH的发送波束的参考信号，并且还可以包含对应PUCCH的功率控制参数。
其中，该参考信号可以是SRS或CSI-RS或服务小区的SSB。如果该参考信号是CSI-RS或SSB，则终端将该CSI-RS或SSB的接收波束作为PUCCH的发送波束，如果该参考信号是SRS，则终端将该SRS的发送波束作为PUCCH的发送波束。
对于每个SRS资源，也可以通过RRC信令配置对应的空间相关信息，其中包含一个用于确定SRS的发送波束的参考信号。
其中，该参考信号可以是SRS或CSI-RS或服务小区的SSB。如果该参考信号是CSI-RS或SSB，则终端将该CSI-RS或SSB的接收波束作为PUCCH的发送波束，如果该参考信号是SRS，则终端将该SRS的发送波束作为PUCCH的发送波束。
如果该SRS资源是用于定位的SRS资源，则空间相关信息中的SSB可以是来自邻小区的SSB。如下面所示，在SRS的空间相关信息中，用于确定SRS的发送波束的参考信号可以是来自服务小区的信号，也可以是来自邻小区的SSB，还可以是下行的定位参考信号。当该参考信号是邻小区的SSB时，网络设备需要在该空间相关信息中进一步指示该SSB的PCID，SSB索引和资源信息，终端根据这些配置就可以进行邻小区SSB的检测。其中，每个SRS资源的空间相关信息中都需要包含这些信息。
下行非相干传输：例如，如图2所示，在下行非相干传输中，多个TRP可以在相同的物理资源上采用不同的控制信道独立调度一个终端的多个PDSCH传输，也可以采用同一个控制信道调度不同TRP 的传输。对于采用多个PDCCH调度的下行传输，所调度的PDSCH可以在相同的时隙或不同的时隙传输。终端需要支持同时接收来自不同TRP的PDCCH和PDSCH。其中，两个TRP可以是同一个小区的不同TRP，也可以是两个不同的物理小区。
上行非相干传输：例如，如图3所示，在上行非相干传输中，不同TRP同样可以独立调度同一个终端的PUSCH传输。不同PUSCH传输可以配置独立的传输参数，例如波束、预编码矩阵、层数等。所调度的PUSCH传输可以在同样的时隙或不同的时隙传输。不同TRP传输的PUSCH可以基于多个DCI进行调度，这些DCI可以通过不同的共复位来承载。其中，协作的两个TRP也可以是两个不同的物理小区。
图4示出了本申请一个示例性实施例提供的通信系统的框图，该通信系统可以包括：接入网12和终端13。
接入网12中包括若干个网络设备120。网络设备120可以是基站，基站是一种部署在接入网中用以为终端提供无线通信功能的装置。基站可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同，例如在LTE系统中，称为eNodeB或者eNB；在5G NR-U系统中，称为gNodeB或者gNB。随着通信技术的演进，“基站”这一描述可能会变化。为方便本申请实施例中，上述为终端13提供无线通信功能的装置统称为接入网设备。
终端13可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备，以及各种形式的用户设备，移动台(Mobile Station，MS)，终端(terminal device)等等。为方便描述，上面提到的设备统称为终端。接入网设备120与终端13之间通过某种空口技术互相通信，例如Uu接口。
本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)系统、先进的长期演进(Advanced long term evolution，LTE-A)系统、新无线(New Radio，NR)系统、NR系统的演进系统、非授权频段上的LTE(LTE-based access to unlicensed spectrum，LTE-U)系统、NR-U系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统、无线局域网(Wireless Local Area Networks，WLAN)、无线保真(Wireless Fidelity，WiFi)、下一代通信系统或其他通信系统等。
通常来说，传统的通信系统支持的连接数有限，也易于实现，然而，随着通信技术的发展，移动通信系统将不仅支持传统的通信，还将支持例如，设备到设备(Device to Device，D2D)通信，机器到机器(Machine to Machine，M2M)通信，机器类型通信(Machine Type Communication，MTC)，车辆间(Vehicle to Vehicle，V2V)通信以及车联网(Vehicle to everything，V2X)系统等。本申请实施例也可以应用于这些通信系统。

本申请实施例提供的方法，通过第一信号的空间相关信息的配置信息中的小区指示信息能够指示该 第一SSB是属于服务小区还是属于邻小区，信令开销低，并且还能够根据第一索引信息确定该第一SSB，基于该第一SSB就能够确定第一信号的发送波束，无需再重复配置邻小区的信息，进一步减小了信令开销。
并且，第一SSB的小区指示信息的比特位仅为1比特，或者通过小区指示信息为空或不为空来指示第一SSB属于服务小区还是邻小区，进一步减小了信令开销。
并且，终端能够根据邻小区配置信息，从邻小区SSB中确定第一SSB，通过邻小区配置信息能够统一配置邻小区中的SSB，无需为每个SSB单独进行配置，减小了信令开销。
图11示出了本申请一个示例性实施例提供的SSB确定方法的流程图。参见图11，该方法包括：
步骤1110、网络设备向终端发送用于CSI测量的SSB集合的第四配置信息。
步骤1120、终端接收网络设备发送的用于CSI测量的SSB集合的第四配置信息。
其中，该第四配置信息中包括第一SSB的小区指示信息和第一索引信息。

Figure PCTCN2020107936-appb-000006
其中，ssb-configuration-r17用于配置第一SSB的参数，包括第一SSB的小区指示信息PhysicalCell和第一索引信息SSB-Index。其中，未配置PhysicalCell时，表示第一SSB为服务小区的SSB；配置PhysicalCell时，表示第一SSB为邻小区的SSB。
可选地，若网络设备为SSB集合配置共用的一个小区指示信息，则用于指示第四配置信息的RRC信令可以为：
Figure PCTCN2020107936-appb-000007
其中，在SSB集合的配置信息(CSI-SSB-ResourceSet)中包括第一SSB的小区指示信息(PhysicalCell)和第一索引信息(csi-SSB-ResourceList)，其中小区指示信息用于指示该SSB集合内的所有SSB。第一索引信息csi-SSB-ResourceList用于指示一组SSB索引。
步骤1130、终端根据第四配置信息中的小区指示信息和第一索引信息，确定第一SSB。
其中步骤1130的过程与上述步骤530的过程类似，在此不再赘述。
步骤1140、终端基于第一SSB进行CSI的测量，确定CSI中包括的第二索引信息和信道质量信息，进行CSI的上报。
其中，第二索引信息为第二SSB在SSB集合中的索引信息，信道质量信息为第二SSB对应的RSRP信息或SINR信息。
可选地，第一SSB为第四配置信息指示的用于CSI测量的SSB集合时，终端对第一SSB集合中的SSB进行RSRP或SINR测量，并将该SSB集合中RSRP或SINR最高的SSB的SSB索引和RSRP或SINR信息通过CSI上报给网络设备。
可选地，该CSI中还包括小区上报信息，该小区上报信息用于指示第二SSB属于服务小区的SSB还是邻小区的SSB。
可选地，终端接收网络设备发送的用于CSI测量的第一SSB集合和第二SSB集合。该第一SSB集合包括服务小区的SSB，该第二SSB集合包括邻小区的SSB。换句话说，两个SSB集合配置中的小区指示信息的内容不同。终端对该第一SSB集合中的SSB和第二SSB集合中的SSB进行测量，将其中RSRP或SINR最高的SSB对应的小区(即小区上报信息)，该SSB的SSB索引(即第二索引信息) 和RSRP(SINR)信息(即信道质量信息)通过CSI上报给网络设备。
若终端从第一SSB集合或第二SSB集合确定第二SSB后，则终端能够确定第二SSB是属于第一SSB集合还是属于第二SSB集合，进而能够确定第二SSB是服务小区的SSB还是邻小区的SSB。
本申请实施例提供的方法，通过用于CSI测量的SSB集合的配置信息中的小区指示信息能够指示该第一SSB是属于服务小区还是属于邻小区，信令开销低，并且还能够根据第一索引信息确定该第一SSB，基于该第一SSB进行CSI上报，无需再重复配置邻小区的信息，进一步减小了信令开销。同时，由于一个SSB集合通常来自同一个物理小区，可以通过配置共同的小区指示信息进一步降低开销。由于非相干传输中只有一个邻小区，只需要配置一个公共的邻小区配置信息，从而只要很低的信令开销就可以支持对邻小区的SSB进行RSRP/SINR的测量和上报，从而支持基于邻小区SSB的波束管理。
