具体实施方式
这里将详细地对示例性具体实施方式执行说明，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。以下示例性具体实施方式中所描述的实施方式并不代表与本申请的具体实施方式相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本申请的一些方面相一致的方法和装置的例子。基于本申请中的具体实施方式，本领域技术人员在没有做出创造性劳动前提下获得的所有其他具体实施方式，都属于本申请的保护范围。
用户终端可以使用多个上行波束来进行上行传输，和/或使用多个下行波束来进行下行的接收。在通信系统中，为了避免直接描述物理概念上的波束，可以采用空间域发送滤波器，或者空间域接收滤波器来描述终端侧的波束。
图1为本申请以下具体实施方式可能应用的通信系统的系统架构。该系统架构包括：基站A，用户终端B。
基站A为指示用户终端B进行上行传输时，可以通过基站A的网络配置 多个SRS(Sounding Reference Signal，信道探测参考信号)资源，用户终端B可以使用不同的空间域发送滤波器传输不同的SRS资源对应的信号，网络通过测量SRS信号，可知道哪个空间域发送滤波器进行传输的效果最好。也可以当用户终端B侧存在波束对应性时，网络获取向用户终端B传输时效果最好的下行传输波束，再根据波束对应性获取对应于下行传输波束的空间域发送滤波器。
因此，当基站A指示用户终端B使用哪个空间域发送滤波器(或者哪个上行波束)进行传输时，可以通过指示信号的标识来间接指示信号的标识对应的空间域发送滤波器。包括：SRS资源标识，同步信号块(SS/PBCH block，SSB)索引，CSI-RS(Channel state information reference signal，信道状态信息参考信号)资源标识，SRS资源标识中可包含SRS资源所在的上行宽带部分标识对应的信息。
对于动态调度的PUSCH(Physical Uplink Shared Channel，物理上行共享信道)，如果基站A的网络只配置了一个用来指示空间域发送滤波器的SRS资源，则用户终端B根据网络配置信息，例如对应的RRC(Radio Resource Control，无线资源控制)信令，确定使用的空间域发送滤波器。如果网络配置了多个用来指示空间域发送滤波器的SRS资源，则用户终端B根据DCI(Downlink control information，下行控制信息)信息所指示的SRS资源，来确定使用的空间域发送滤波器。对于半持续调度的PUSCH，如果RRC参数configuredGrantConfig(准许配置)中包含参数rrc-ConfiguredUplinkGrant(RRC上行准许配置)，用户终端B根据RRC参数中指示的SRS资源标识，确定使用的空间域发送滤波器，如果RRC参数configuredGrantConfig中不包含参数rrc-ConfiguredUplinkGrant，用户终端B根据DCI信息指示的SRS资源，确定使用的空间域发送滤波器。
对于SRS传输，通过配置SRS的空间关系信息，其中空间关系信息中可以指示RRC参数参加SRS资源标识或SSB(Synchronization Signal Block，Synchronization signal/PBCH block，同步信号块)索引或CSI-RS(Channel state information reference signal，信道状态信息参考信号)资源标识的信令格式，SRS资源标识中可包含SRS资源所在的上行宽带部分标识对应的信 息。从而根据信号的标识指示对应的空间域发送滤波器。
对于PUCCH(Physical Uplink Control Channel，物理上行控制信道)传输，通过配置PUCCH的空间信息关系，其中空间信息关系中可以通过RRC参数指示SRS资源标识或SSB索引或CSI-RS(Channel state information reference signal，信道状态信息参考信号)资源标识，SRS资源标识中可包含SRS资源所在的上行宽带部分标识对应的信息。从而根据SRS资源的标识、或SSB索引、或CSI-RS资源标识指示对应的空间域发送滤波器。
针对PUCCH，如果网络只配置了一个PUCCH的空间关系信息(例如，配置了一个PUCCH-SpatialRelationInfo(PUCCH空间关系信息))，则所有的PUCCH资源都根据该空间关系信息确定使用的空间域发送滤波器。网络配置了多个PUCCH空间关系信息，则每个PUCCH资源都根据网络的进一步指示/配置/激活信息(例如媒体接入控制单元)指示的空间关系信息，来确定使用的空间域发送滤波器
网络侧配置空间关系信息会为系统提供最大的灵活性，但同时也会为系统带来较大的信令开销。因此为节省信令开销，网络侧可以不配置空间关系信息。但是，在现有的确定空间域发送滤波器的方法中，网络侧未配置空间关系信息时无法确定上行传输的空间域发送滤波器。本申请以下具体实施方式将详细描述如何在基站A未配置空间关系信息时，确定上行传输的空间域发送滤波器。
在本系统架构中，该示例通信系统可以是全球移动通信系统(Global System for Mobile communications，GSM)，码分多址(Code Division Multiple Access，CDMA)系统，时分多址(Time Division Multiple Access，TDMA)系统，宽带码分多址(Wideband Code Division Multiple Access Wireless，WCDMA)，频分多址(Frequency Division Multiple Addressing，FDMA)系统，正交频分多址(Orthogonal Frequency-Division Multiple Access，OFDMA)系统,单载波FDMA(SC-FDMA)系统，通用分组无线业务(General Packet Radio Service，GPRS)系统，LTE(Long Term Evolution，长期演进)系统，5G(5th-Generation，第五代移动通信技术)NR(NR Radio Access，新无线接入)系统以及其他此类通信系统。该示例通信系统具体包括网络 侧设备和终端，终端接入网络侧设备提供的移动通信网络时，终端与网络侧设备之间可以通过无线链路通信连接，该通信连接方式可以是单连接方式或者双连接方式或者多连接方式，但通信连接方式为单连接方式时，网络侧设备可以是LTE基站或者NR基站(又称为gNB基站)，当通信方式为双连接方式时(具体可以通过载波聚合CA技术实现，或者多个网络侧设备实现)，且终端连接多个网络侧设备时，该多个网络侧设备可以是主基站MCG和辅基站SCG，基站之间通过回程链路backhaul进行数据回传，主基站可以是LTE基站，辅基站可以是LTE基站，或者，主基站可以是NR基站，辅基站可以是LTE基站，或者，主基站可以是NR基站，辅基站可以是NR基站。本申请具体实施方式所描述的接收侧RLC实体可以是终端或终端中的软件(如协议栈)和/或硬件(如调制解调器)，同样的，发送侧RLC实体可以是网络侧设备或网络侧设备中的软件(如协议栈)和/或硬件(如调制解调器)。
本申请具体实施方式中，名词“网络”和“系统”经常交替使用，本领域技术人员可以理解其含义。
本申请具体实施方式所涉及到的用户终端可以包括各种具有无限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(User Equipment，UE)，移动台(Mobile Station，MS)，终端设备(terminal device)等等。为方便描述，上面提到的设备统称为终端。
另外，本文中术语“系统”和“网络”在本文中常被可互换使用。本文
中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
应理解，在本申请具体实施方式中，“与A相应的B”表示B与A相关联，根据A可以确定B。但还应理解，根据A确定B并不意味着仅仅根据A确定B，还可以根据A和/或其它信息确定B。
图2是根据本申请具体实施方式的一种确定空间域发送滤波器的方法的流程图。如图2所示，该确定空间域发送滤波器的方法应用于用户终端，其可以包括以下步骤：
在步骤110中，根据网络侧配置的传输配置指示状态TCI-State和/或配置信息和/或传输状况，确定传输资源的空间域发送滤波器。
其中，UE在进行信号接收时，为了提高接收性能，可以利用数据传输所对应的传输环境的特性来改进接收算法。例如可以利用信道的统计特性来优化信道估计器的设计和参数。数据传输所对应的传输环境的特性通过QCL(Quasi Co-Location，准共址)信息来表示。
下行传输如果来自不同的TRP(Transmission and Reception Point，接收点)或panel(天线面板)或波束，则数据传输对应所对应的传输环境的特性可能也会有变化，因此网络侧在传输下行信道(包括下行控制信道和下行数据信道)或下行信号，会通过TCI-State(Transmission Configuration Indication-State，传输配置指示状态)将对应的QCL信息指示给UE。
TCI-State可以包含以下配置：TCI-State的标识，用于标识TCI-State，QCL信息1，QCL信息2(可选)。
QCL信息可以包含以下信息：QCL类型配置，可以包括QCL type(类型)A，QCL typeB，QCL typeC，QCL typeD中的一个。还可以包括QCL参考信号配置，包括参考信号所在的小区标识，带宽部分标识，以及参考信号的标识(可以是CSI-RS资源标识或SSB索引)。如果QCL信息1和QCL信息2都配置了，则至少一个QCL信息的QCL类型为typeA，typeB，typeC中的一个，另一个QCL信息的QCL类型为QCL typeD。
如果网络侧通过TCI-State配置的下行信道或下行信号的QCL参考信号为参考CSI-RS资源，或者参考SSB，且QCL类型配置为typeA或typeB或typeC，则UE可以假设下行信号与参考SSB或参考CSI-RS资源的大尺度参数相同，该大尺度参数通过QCL类型配置来确定。
如果网络侧通过TCI-State配置的下行信道或下行信号的QCL参考信号为参考CSI-RS资源，或者参考SSB，且QCL类型配置为typeD，则UE可以采用与接收参考SSB或参考CSI-RS资源，即参考信号相同的接收波束，来接收 下行信号。下行信道(或下行信号)与它的参考SSB或参考CSI-RS资源在网络侧由同一个TRP或者同一个panel或者相同的波束来传输。如果两个下行信号或下行信道的传输TRP或传输panel或传输波束不同，通常会配置不同的TCI-State。
对于下行控制信道，可以通过RRC信令或者RRC信令和MAC(Media Access Control，媒体接入控制)层信令的方式来指示激活TCI-State。
对于下行数据信道，可用的TCI-State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-State，最后通过DCI中的TCI-State指示域从激活的TCI-State中指示一个或两个TCI-State，用于DCI调度的PDSCH(Physical Downlink Shared Channel，物理下行共享信道)。两个TCI-State的情况针对于多个TRP的场景。
空间域发送滤波器为进行上行传输的空间域滤波器。根据网络侧配置的传输配置指示状态TCI-State中包含的信息，确定传输资源的空间域发送滤波器。配置信息和传输状况可以不包含空间关系信息。配置信息为该UE确定空间域发送滤波器的之前，UE配置的信号信息，包括：进行传输(发送和/或接收)资源的空间域发送滤波器信息，进行传输的信号的信息等。传输状况为UE之前进行传输的状态信息，包括：最近一次PUSCH传输的空间域发送滤波器，最近一次PUCCH传输的空间域发送滤波器等。根据UE的配置信息和/或传输状况，确定进行上行传输的空间域发送滤波器。从而不依赖于空间关系信息，确定空间域发送滤波器的。
此具体实施方式实现了根据网络侧配置的传输配置指示状态TCI-State和/或配置信息和/或传输状况，确定传输资源的空间域发送滤波器，解决无法不依赖于空间关系信息确定空间域发送滤波器的技术问题。
在一个示例性具体实施方式中，资源包括未配置对应的空间关系信息的资源。从而可以不依赖于空间关系信息，确定传输资源的空间域发送滤波器。
图3是本申请一种实施方式的一种确定空间域发送滤波器的的方法的 流程图。如图3所示，该步骤110包括：
则上述图2对应的具体实施方式中的步骤110在一个实施例的具体流程包括步骤111，步骤112，步骤113，步骤114，步骤115，步骤116，步骤117和步骤118。
在步骤111中，根据控制资源集CORESET对应的TCI-State中准共址QCL信息的类型typeD对应的参考信号，确定传输资源的空间域发送滤波器。
其中，CORESET(控制资源集)为新无线(NR)系统中的资源单位，CORESET可以配置有对应的TCI-State，TCI-State中包含有QCL信息的typeD。根据typeD对应参考信号，确定传输资源的空间域发送滤波器。
该CORESET可以为带宽部分中配置的标识最小的CORESET，通过采用相对固定的方式，降低UE对波束变化的跟踪或记录的操作，减少UE处理的复杂度；该CORESET也可以为带宽部分中配标识大于0中标识最小的CORESET，从而排除UE初始接入时就已经有的CORESET。
该CORESET还可以为调度载波中标识最小的CORESET，该调度载波用于传输下行控制信息(DCI)调度信息。通过采用相对固定的方式，降低UE对波束变化的跟踪或记录的操作，减少UE处理的复杂度；该CORESET还可以为调度载波中标识大于0中标识最小的CORESET，从而排除UE初始接入时就已经有的CORESET。
该TCI-State为该CORESET对应的激活的TCI-State，该激活的TCI-State可以是该CORESET对应的唯一一个TCI-State，也可以是该CORESET对应的多个TCI-State中，被媒体接入控制单元(MAC CE)信令激活了的某个TCI-State。
当该CORESET中对应的多个TCI-State未收到MAC CE信令进行激活时，即该CORESET不存在对应的激活的TCI-State，此时该TCI-State为CORESET对应的标识最小的TCI-State。
CORESET对应的TCI-State中QCL信息的typeD对应的参考信号包括信道状态信息参考信号(CSI-RS)和/或同步信号块，当参考信号为CSI-RS和/或SSB时，根据CORESET对应的TCI-State中QCL信息的typeD对应的参考信号，确定传输资源的空间域发送滤波器与接收参考信号的空间域滤波器相 同。
此具体实施方式的具体实现中，UE可以为不依赖于上行波束扫描的波束对应性的UE。
在步骤112中，根据最近一次物理上行共享信道PUSCH传输确定传输资源的空间域发送滤波器，空间域发送滤波器与最近一次PUSCH传输使用的空间域滤波器相同。
其中，UE根据最近的一次PUSCH传输来确定传输资源的空间域发送滤波器，该空间域发送滤波器与最近一次PUSCH传输使用的空间域滤波器相同，从而当部分SRS资源配置空间关系信息，并且用来支持上行PUSCH传输时，充分利用上行波束动态指示来更新其他上行波束指示，采用相同的空间域滤波器作为空间域发送滤波器，增加系统灵活性，提高系统性能。
此具体实施方式的具体实现中，UE可以为依赖于上行波束扫描的波束对应性的UE。
