Signaling is provided by PUCCH-Spatialrelationinfo. When the spatial relationship table has only one entry, the entry takes effect directly.

Description

波束指示方法、装置和系统 技术领域
本发明涉及通信领域，特别涉及一种波束指示方法、装置和系统。
背景技术
为了增强通信系统在高频段的吞吐量和覆盖，在载波频率大于6GHz的情况下，新无线(NR)系统引入了波束管理机制。
对于下行而言，数据信道(PDSCH)的波束指示机制如下：网络设备通过高层信令配置传输配置指示状态(Transmission Configuration Indication State，TCI state)。TCI中的每个状态对应一个或者多个下行参考信号，用于确定天线端口的准定位同步(QCL，quasi co-located)。
当某个控制资源集合(CORESET)的TCI-PresentInDCI字段被设为“使能”，则终端设备认为在该CORESET上的下行控制信息(DCI)存在TCI区域。与此同时，如果调度间隔(Scheduling Offset)大于预先设定的阈值Threshold-Sched-Offset，终端设备根据TCI区域所指示的TCI-States来确定天线端口的准定位同步。
当某个CORESET的TCI-PresentInDCI字段被设为“去使能”，或是由DCI format1_0调度PDSCH，则终端设备认为在该CORESET上的DCI不存在TCI区域。与此同时，如果调度间隔(Scheduling Offset)大于预先设定的阈值Threshold-Sched-Offset，终端设备接收PDSCH的TCI状态与CORESET所应用的TCI状态相同。
针对以上所有情景，如果调度间隔(Scheduling Offset)小于预先设定的阈值Threshold-Sched-Offset时，终端设备接收PDSCH的TCI状态与最近时隙最小编号的CORESET所使用的TCI状态相同。
对于上行数据信道(PUSCH)而言，其波束指示机制如下：对于被DCI format 0_0调度的PUSCH，终端设备根据当前小区被激活的BWP上最小编号PUCCH资源的空间关系发送PUSCH。对于被DCI format 0_1调度的PUSCH，终端设备根据DCI中参考信号资源指示(SRI)区域所指示的探测参考信号(SRS)的空间关系发送PUSCH。
对于上行控制信道(PUCCH)而言，其波束指示机制如下：在特定的RRC信令配置了PUCCH资源之后，所有PUCCH资源的空间关系将由一个空间关系表所指示， 该表的每个条目由高层信令PUCCH-Spatialrelationinfo所提供。当该空间关系表仅有一个条目时，该条目直接生效。当该空间关系表包含多个条目的时候，每一个PUCCH资源，通过媒体接入控制单元(MAC-CE)信令激活其中的一个条目。
此外，在NR系统中也引入了半持续调度的机制。半持续调度(SPS)是指网络设备半静态配置无线资源，并将该无线资源周期性地分配给某个特定终端设备。这种调度方式的好处是，可以节省控制信令(PDCCH)的开销。在最新的无线系统演进中(Release 15)，半持续调度的功能被进一步增强。以下分别从上行和下行两个方面介绍现有的半持续调度的机制。
对于下行链路而言，仅有数据信道(PDSCH)可以被配置为半持续调度。网络设备(gNB)通过无线资源控制(RRC)信令配置半持续调度的周期、混合自动重传请求(HARQ)进程数以及HARQ所使用的PUCCH资源。当下行半持续调度配置完成后，不能立即使用，必须使用小区调度无线网络临时标识(CS-RNTI)加扰的DCI激活。当半持续调度结束时，必须使用CS-RNTI加扰的DCI去激活。
对于上行链路而言，对数据信道(PUSCH)以及信道状态信息反馈(CSI Report)都可以配置为半持续调度。
对于承载PUSCH的上行链路，SPS可以分为两种：Type 1 PUSCH transmissions with a configured grant(Type 1)和Type 2 PUSCH transmissions with a configured grant(Type 2)。Type 1是指该上行调度的资源仅由RRC信令配置，配置的信息包括频率资源信息、时间资源信息、周期信息、SRI等。Type1的传输不需要DCI激活，在RRC配置完成后开始传输。Type 2是指该上行调度的一部分信息由RRC配置，配置完成后，该调度不能立即执行，必须使用CS-RNTI加扰的DCI激活。当该上行调度结束时，必须使用CS-RNTI加扰的DCI去激活。
对于承载信道状态信息反馈的上行链路，SPS可以分为三种：基于PUCCH的半持续CSI上报；基于PUSCH的半持续CSI上报；基于PUCCH的周期性CSI上报。其中，基于PUCCH的半持续CSI上报在RRC配置完成之后，需要使用MAC-CE信令激活、去激活；基于PUSCH的半持续CSI上报在RRC配置完成之后，需要使用半静态调度-信道状态信息-无线网络临时标识(SP-CSI-RNTI)加扰的DCI激活、去激活；基于PUCCH的周期性CSI上报在RRC配置完成之后直接生效。
应该注意，上面对技术背景的介绍只是为了方便对本发明的技术方案进行清楚、 完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本发明的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
发明人发现，当网络设备为终端设备配置了上述半持续调度之后，对半持续调度的波束指示是模糊的。
如图1所示，半持续调度的波束指示可以分为三大类场景。每种场景对半持续调度的激活方式有所不同，分别是DCI(CS-RNTI或者SP-CSI-RNTI)，MAC-CE和RRC。对于每个场景而言，激活信令触发之后的第一次传输(记为#1)可以基于现有的波束指示方式来确定。然而，在相应的第一次传输之后，到下一次激活或去激活信令之前，终端设备不清楚用哪个波束上传或接收。

实施例1
本实施例提供了一种波束指示方法，该方法应用于终端设备。图3是本实施例的波束指示方法的示意图，请参照图3，该方法包括：
步骤301：终端设备接收激活信令，所述激活信令激活至少一个传输(transmission)；
步骤302：所述终端设备根据以下理解对所述至少一个传输进行发送或接收：在接收到去激活信令或者下一次激活信令之前，所述激活信令所激活的所有传输，使用相同的空域滤波器或者传输假设，或者使用通过动态解读所述激活信令而确定的各自的空域滤波器或者传输假设。
在本实施例中，上述激活信令可以是CS-RNTI加扰的DCI，也可以是SP-CSI-RNTI加扰的DCI，还可以是MAC-CE，或者是RRC信令，但本实施例并不以此作为限制，根据通信标准的进展，该激活信令也可以是其他信令。
在本实施例中，上述至少一个传输可以是半持续调度的下行传输，例如PDSCH；也可以是半持续调度的上行传输，例如Type1 PUSCH transmission、Type2 PUSCH transmission、基于PUSCH的半持续CSI上报、基于PUCCH的半持续CSI上报；还可以是基于上行传输的周期性CSI，例如基于PUCCH的周期性CSI上报。然而，本实施例并不以此作为限制，上述至少一个传输还可以是其他类型的上行传输或者下行传输。
在本实施例中，使用相同的空域滤波器或者传输假设是指：上述激活信令所激活的所有传输都依据相同的空域滤波器或者参考信号；或者，在激活信令和该激活信令所激活的第一个传输之间的调度距离大于预先设定的阈值的情况下，上述激活信令所激活的所有传输中第一个传输依据该激活信令所指示的空域滤波器或者参考信号，除第一个传输以外的所有传输都依据与第一个传输相同的空域滤波器或者参考信号；或者，在激活信令和该激活信令所激活的第一个传输之间的调度距离小于预先设定的阈值的情况下，该预先设定的阈值之后的第一个传输依据上述激活信令所指示的空域滤 波器或者参考信号，该预先设定的阈值之后的、除第一个传输以外的所有传输都依据与第一个传输相同的空域滤波器或者参考信号。这里，预先设定的阈值在现有标准中被称为threshold-Sched-Offset，关于其设定的方式和原则与现有标准相同，此处不再赘述。
在本实施例中，使用通过动态解读所述激活信令而确定的各自的空域滤波器或者传输假设是指：上述激活信令所激活的每个传输各自依据该激活信令在预定时刻的解读而确定的空域滤波器或者参考信号。这里，对每个传输来说，其各自的预定时刻是一定的，本实施例对各个传输各自的预定时刻的设定方式不作限制。
下面结合不同的实施方式(场景)对本实施例的波束指示方法进行说明。
实施方式1：
在本实施方式中，上述至少一个传输为半持续调度的下行传输，激活信令为被CS-RNTI加扰的DCI，该DCI不包含TCI区域，并且，激活信令和该激活信令所激活的第一个传输之间的调度距离(也即背景技术所描述的调度间隔)大于预先设定的阈值Threshold-Sched-Offset，则终端设备可以根据下面任意一种理解接收该半持续调度的下行传输：
理解一：被上述DCI激活的第一个传输的TCI状态与承载该DCI的资源控制集合(CORESET)所应用的TCI状态相同，被上述DCI激活的除第一个传输以外的其他传输依据与第一个传输相同的、用于确定天线端口准定位同步的参考信号；
理解二：被上述DCI激活的每个传输的TCI状态和一个CORESET在最近时隙中所应用的TCI状态相同，如果承载上述DCI的CORESET存在，则该一个CORESET是指承载上述DCI的CORESET；如果承载上述DCI的CORESET不存在，则该一个CORESET是指，处于与上述DCI同小区的被激活的载波带宽(BWP)上编号最小的CORESET。
下面以半持续调度的下行传输为PDSCH为例对本实施方式进行说明。
在本实施方式中，在下行传输中，当网络设备通过高层信令(如RRC信令)完成了半持续调度参数的配置以后，半持续调度的PDSCH被CS-RNTI加扰的DCI激活。此时，DCI不包含TCI区域，或者可以理解为该DCI满足以下条件，即这个DCI的格式是1_0或者传输该DCI的CORESET的高层参数TCI-PresentInDCI被设为“去使能”。如果该DCI和被它激活的第一个半持续调度的PDSCH的调度距离大于 Threshold-Sched-Offset。则以下的波束指示方法可以用于被该DCI激活的半持续调度的PDSCH：
方法1：被该DCI激活的第一个PDSCH的TCI状态与承载该DCI的CORESET所应用的TCI状态相同。在被下一个(与上述DCI同小区的)被CS-RNTI加扰的DCI重激活/去激活之前，被该DCI激活的之后的PDSCH的、和被该DCI激活的第一个PDSCH(为了确定天线端口准定位同步)所使用的参考信号是相同的。在该方法1中，所有确定PDSCH天线端口准定位同步的参考信号在DCI重新激活/去激活之前是相同的，由此降低了系统复杂度。
方法2：在被下一个(与上述DCI同小区的)被CS-RNTI加扰的DCI重激活/去激活之前，终端设备认为每个被该DCI激活的PDSCH的TCI状态会和一个CORESET在最近时隙中所应用的TCI状态相同。这个CORESET是指，如果承载激活信令的CORESET存在，它是承载激活指令(CS-RNTI加扰的DCI)的CORESET；如果上述承载激活信令的CORESET不存在，则它是指处于(与上述DCI同小区的)被激活的BWP上编号最小的CORESET。在该方法2中，每个确定PDSCH天线端口准定位同步的参考信号都可以动态地跟随CORESET的TCI状态所关联的参考信号。在波束方向时常发生变化的场景下，无需多次使用DCI重激活来更改波束指示，减少了DCI的开销。
实施方式2：
在本实施方式中，上述至少一个传输为半持续调度的下行传输，激活信令为被CS-RNTI加扰的DCI，该DCI不包含TCI区域，激活信令和该激活信令所激活的第一个传输之间的调度距离小于预先设定的阈值Threshold-Sched-Offset，则该终端设备可以根据下面任意一种理解接收该半持续调度的下行传输：
理解一：对于被上述DCI激活的传输，在上述预先设定的阈值之前的传输的TCI状态与最近时隙的(与上述DCI同小区的)被激活的BWP上编号最小的CORESET的TCI状态相同，在上述预先设定的阈值之后的第一个传输的TCI状态与承载该DCI的CORESET的TCI状态相同，在上述预先设定的阈值之后的除第一个传输以外的其他传输依据与第一个传输相同的、用于确定天线端口准定位同步的参考信号；
理解二：对于被上述DCI激活的传输，在上述预先设定的阈值之前的传输的TCI状态与最近时隙的(与上述DCI同小区的)被激活的BWP上编号最小的CORESET 的TCI状态相同，在上述预先设定的阈值之后的传输的TCI状态和一个CORESET在最近时隙中的TCI状态相同，该一个CORESET是指，如果承载该DCI的CORESET存在，它是指承载上述DCI的CORESET；或者，如果承载该DCI的CORESET不存在，则上述一个CORESET是指，处于与上述DCI同小区的被激活的BWP上编号最小的CORESET；
理解三：被上述DCI激活的每个传输的TCI状态和最近时隙与上述DCI同小区的被激活的BWP中编号最小CORESET的TCI状态相同。
下面以半持续调度的下行传输为PDSCH为例对本实施方式进行说明。
在本实施方式中，在下行传输中，当网络设备通过高层信令(如RRC信令)完成了半持续调度参数的配置以后，半持续调度的PDSCH被CS-RNTI加扰的DCI激活。此时，DCI不包含TCI区域，或者可以理解为该DCI满足以下条件，即这个DCI的格式是1_0或者传输该DCI的CORESET的RRC参数TCI-PresentInDCI被设为“去使能”。如果该DCI和被它激活的第一个半持续调度的PDSCH的调度距离小于Threshold-Sched-Offset。则如下的波束指示方法可以用于被该DCI激活的半持续调度的PDSCH：
方法1：终端设备认为：每个(被该DCI激活的)在Threshold-Sched-Offset之前的PDSCH的TCI状态与最近时隙的(与上述DCI同小区的)被激活的BWP上编号最小CORESET的TCI状态相同。被该DCI激活的第一个超过Threshold-Sched-Offset的PDSCH的TCI状态与承载该DCI的CORESET的TCI状态相同。在被下一个(与上述DCI同小区的)被CS-RNTI加扰的DCI重激活/去激活之前，被该DCI激活的第一个超过Threshold-Sched-Offset的PDSCH和之后的PDSCH(为了确定天线端口准定位同步)所使用的参考信号是相同的。在该方法1中，所有确定PDSCH天线端口准定位同步的参考信号在Threshold-Sched-Offset之后并且在DCI重新激活/去激活之前都是相同的，由此降低了系统复杂度。
方法2：终端设备认为：每个(被该DCI激活的)在Threshold-Sched-Offset之前的PDSCH的TCI状态与最近时隙的(与上述DCI同小区的)激活的BWP上编号最小CORESET的TCI状态相同。在被下一个(与上述DCI同小区的)被CS-RNTI加扰的DCI重激活/去激活之前，每个被该DCI激活的超过Threshold-Sched-Offset的PDSCH的TCI状态会和一个CORESET在最近时隙中的TCI状态相同。这个 CORESET是指，如果承载激活信令的CORESET存在，它是承载激活指令(被CS-RNTI加扰的DCI)的CORESET；如果承载激活信令的CORESET不存在，则它是指处于(与上述DCI同小区的)被激活的BWP上编号最小的CORESET。在方法2中，所有确定PDSCH天线端口准定位同步的参考信号在Threshold-Sched-Offset之后并且在DCI重新激活/去激活之前可以动态地跟随控制信道的TCI状态。在波束方向时常发生变化的场景，无需多次使用DCI重激活来更改波束指示，减少了DCI的开销。
方法3：终端设备认为：在被下一个(与上述DCI同小区的)被CS-RNTI加扰的DCI重激活/去激活之前，每个被该DCI激活的PDSCH的TCI状态会和最近时隙(与上述DCI同小区的)被激活的BWP中编号最小CORESET的TCI状态相同。在方法3中，终端设备依据默认的随接收时间动态变化的参考信号接收PDSCH。在波束方向时常发生变化的场景，无需多次使用DCI重激活来更改波束指示，减少了DCI的开销。
实施方式3：
在本实施方式中，上述至少一个传输为半持续调度的下行传输，激活信令为被CS-RNTI加扰的DCI，该DCI包含TCI区域，激活信令和该激活信令所激活的第一个传输之间的调度距离大于预先设定的阈值Threshold-Sched-Offset，则终端设备可以根据下面任意一种理解接收该半持续调度的下行传输：
理解一：被上述DCI激活的第一个传输的TCI状态由该DCI的TCI区域所指示的、在与接收第一个传输相同的BWP上的TCI-state中的TCI状态决定，被上述DCI激活的除第一个传输以外的其他传输依据与第一个传输相同的、用于确定天线端口准定位同步的参考信号；
理解二：被上述DCI激活的每个传输的TCI状态与根据该DCI的TCI区域所指示的、在与接收该传输相同的BWP上的最近时隙的TCI-state相同。
下面以半持续调度的下行传输为PDSCH为例对本实施方式进行说明。
在本实施方式中，在下行传输中，在网络设备通过高层信令(如RRC信令)完成了半持续调度参数的配置以后，该半持续调度的PDSCH被CS-RNTI加扰的DCI激活。此时，DCI包含TCI区域，或者可以理解为该DCI满足以下条件，即这个DCI的格式是1_1且传输该DCI的CORESET的RRC参数TCI-PresentInDCI被设为“使 能”。如果该DCI和它激活的第一个半持续调度的PDSCH的调度距离大于Threshold-Sched-Offset。则以下的波束指示方法可以用于被该DCI激活的半持续调度的PDSCH：
方法1：被该DCI激活的第一个PDSCH的TCI状态由该DCI的TCI区域所指示的(在与接收该PDSCH相同的BWP上的)TCI-state中的TCI状态决定。在被下一个(与上述DCI同小区的)被CS-RNTI加扰的DCI重激活/去激活之前，被该DCI激活的之后的PDSCH和被该DCI激活的第一个PDSCH(为了确定天线端口准定位同步)所使用的参考信号是相同的。在方法1中，所有确定PDSCH天线端口准定位同步的参考信号在DCI重新激活之前是相同的，由此降低了系统复杂度。
方法2：在被下一个(与上述DCI同小区的)被CS-RNTI加扰的DCI重激活/去激活之前，对于每个被该DCI激活的PDSCH而言，终端设备的TCI状态与根据该DCI的TCI区域所指示的(在与接收该PDSCH相同的BWP上的)最近时隙的TCI-state相同。也就是说，该TCI-state有两个条件，条件1，与接收PDSCH的BWP相同，条件2，在最近时隙(in the latest slot)。在方法2中，每个确定PDSCH天线端口准定位同步的参考信号都可以动态地跟随TCI-state所表示的TCI状态动态改变。在波束方向时常发生变化的场景无需再次使用DCI重新激活，减少了DCI的开销。
实施方式4：
在本实施方式中，上述至少一个传输为半持续调度的下行传输，激活信令为被CS-RNTI加扰的DCI，该DCI包含TCI区域，激活信令和该激活信令所激活的第一个传输之间的调度距离小于预先设定的阈值Threshold-Sched-Offset，则终端设备可以根据下面任意一种理解接收该半持续调度的下行传输：
理解一：对于被上述DCI激活的传输，在上述预先设定的阈值之前的传输的TCI状态与最近时隙的(与上述DCI同小区的)被激活的BWP上编号最小的CORESET的TCI状态相同，在上述预先设定的阈值之后的第一个传输的TCI状态由上述DCI的TCI区域所指示的、在与接收第一个传输相同的BWP上的TCI-state所决定，在上述预先设定的阈值之后的除第一个传输以外的其他传输依据与第一传输相同的、用于确定天线端口准定位同步的参考信号；
理解二：对于被上述DCI激活的传输，在上述预先设定的阈值之前的传输的TCI状态与最近时隙的(与上述DCI同小区的)被激活的BWP上编号最小的CORESET 的TCI状态相同，在上述预先设定的阈值之后的每个传输的TCI状态由上述DCI的TCI区域所指示的、在与接收所述第一个传输相同的BWP上的TCI-state所决定；
理解三：被上述DCI激活的每个传输的TCI状态和最近时隙与该DCI同小区的被激活的BWP中编号最小CORESET的TCI状态相同。
下面以半持续调度的下行传输为PDSCH为例对本实施方式进行说明。
在本实施方式中，在下行传输中，在网络设备通过高层信令(如RRC信令)完成了半持续调度参数的配置以后，该半持续调度的PDSCH被CS-RNTI加扰的DCI激活。此时，DCI包含TCI区域，或者可以理解为该DCI满足以下条件，即这个DCI的格式是1_1且传输该DCI的CORESET的RRC参数TCI-PresentInDCI被设为“使能”。如果该DCI和它激活的第一个半持续调度的PDSCH的调度距离小于Threshold-Sched-Offset。则以下的波束指示方法可以用于被该DCI激活的半持续调度的PDSCH：
方法1：终端设备假设每个(被该DCI激活的)在Threshold-Sched-Offset之前的PDSCH的TCI状态与最近时隙的(与上述DCI同小区的)被激活的BWP上编号最小CORESET的TCI状态相同。被该DCI激活的第一个超过Threshold-Sched-Offset的PDSCH的TCI状态由该DCI的TCI区域所指示的(在与接收该PDSCH相同的BWP上的)TCI-state所决定。在被下一个(与上述DCI同小区的)被CS-RNTI加扰的DCI重激活/去激活之前，被该DCI激活的第一个超过Threshold-Sched-Offset的PDSCH和之后的PDSCH(为了确定天线端口准定位同步)所使用的参考信号是相同的。在方法1中，所有确定PDSCH天线端口准定位同步的参考信号在Threshold-Sched-Offset之后并且在DCI重新激活之前都是相同的，由此降低了系统复杂度。
方法2：终端设备假设每个(被该DCI激活的)在Threshold-Sched-Offset之前的PDSCH的TCI状态与最近时隙的(与上述DCI同小区的)被激活的BWP上编号最小CORESET的TCI状态相同。在被下一个(与上述DCI同小区的)被CS-RNTI加扰的DCI重激活/去激活之前，终端设备认为每个被该DCI激活的超过Threshold-Sched-Offset的PDSCH的TCI状态由该DCI的TCI区域所指示的(在与接收该PDSCH相同的BWP上的)最近时隙的TCI-state所决定。在方法2中，所有确定PDSCH天线端口准定位同步的参考信号在Threshold-Sched-Offset之后并且在DCI 重新激活之前可以动态地跟随控制信道的TCI状态。在波束方向时常发生变化的场景，无需多次使用DCI重激活来更改波束指示，减少了DCI的开销。
方法3：在被下一个(与上述DCI同小区的)被CS-RNTI加扰的DCI重激活/去激活之前，终端设备认为每个被该DCI激活的PDSCH的TCI状态会和最近时隙(与上述DCI同小区的)被激活的BWP中编号最小CORESET的TCI状态相同。在方法3中，终端设备依据默认的随接收时间动态变化的参考信号接收PDSCH。在波束方向时常发生变化的场景，无需多次使用DCI重激活来更改波束指示，减少了DCI的开销。
实施方式5：
在本实施方式中，上述至少一个传输为半持续调度的上行传输，激活信令为RRC信令，并且，上述传输为类型1的上行传输，则终端设备可以根据下面任意一种理解发送该半持续调度的上行传输：
理解一：根据上述RRC信令中rrc-ConfiguredUplinkGrant中的srs-ResourceIndicator确定被该RRC信令激活的第一个传输的空间关系，被该RRC信令激活的除第一个传输以外的其他传输所依据的表示空间关系的参考信号与第一个传输所依据的表示空间关系的参考信号相同；
理解二：根据上述RRC信令中rrc-ConfiguredUplinkGrant中的srs-ResourceIndicator确定被该RRC信令激活的第一个传输的空间关系，被该RRC信令激活的除第一个传输以外的其他传输所使用的空域滤波器与第一个传输所使用的空域滤波器相同；
理解三：被上述RRC信令激活的每个传输的空间关系根据该RRC信令中rrc-ConfiguredUplinkGrant中的srs-ResourceIndicator指示SRS资源的最近时隙的空间关系确定。
下面以半持续调度的上行传输为Type1 PUSCH transmission(简称为PUSCH#1)为例对本实施方式进行说明。
在本实施方式中，在上行传输中，在网络设备通过高层信令(如RRC信令)完成了半持续调度参数的配置以后，该RRC信令同时激活了半持续调度的Type1PUSCH transmission，也即Type 1 PUSCH transmissions开始传输。则以下的波束指示方法可以用于该PUSCH#1：
方法1：终端设备根据rrc-ConfiguredUplinkGrant中的srs-ResourceIndicator确定被激活的第一个PUSCH#1的空间关系。在rrc-ConfiguredUplinkGrant被重配置之前，发送之后的(被激活的)PUSCH#1所依据的表示空间关系的参考信号与发送第一个(被激活的)PUSCH#1所依据的表示空间关系的参考信号相同。在方法1中，发送PUSCH#1所依据的参考信号在rrc-ConfiguredUplinkGrant被重配置之前始终不变，降低了系统复杂度。
方法2：终端设备根据rrc-ConfiguredUplinkGrant中的srs-ResourceIndicator确定被激活的第一个PUSCH#1的空间关系。在rrc-ConfiguredUplinkGrant被重配置之前，发送第一个(被激活的)PUSCH#1的空域滤波器与发送之后的(被激活的)PUSCH#1的空域滤波器相同。在方法2中，发送PUSCH#1的空域滤波器在rrc-ConfiguredUplinkGrant被重配置之前始终不变，降低了系统复杂度。
方法3：在rrc-ConfiguredUplinkGrant被重配置之前，每个被激活的PUSCH#1的空间关系将基于srs-ResourceIndicator指示SRS资源的最近时隙的空间关系确定。在方法3中，发送PUSCH#1的空域滤波器跟随srs-ResourceIndicator所指示的SRS资源的空间关系动态改变，在波束方向时常发生变化的场景无需RRC信令重新配置，减少了DCI的开销。
在本实施方式的一个变型例中，还可以在rrc-ConfiguredUplinkGrant中增加一个配置条目(也称为信元)，例如SRI-Present，通过该配置条目来指示srs-ResourceIndicator是否存在，例如，当该配置条目设为“使能”时，srs-ResourceIndicator将出现在rrc-ConfiguredUplinkGrant中，终端设备可以根据前述理解发送该半持续调度的Type1 PUSCH transmission；当该配置条目设为“去使能”时，rrc-ConfiguredUplinkGrant中将没有srs-ResourceIndicator，终端设备可以根据下面任意一种理解发送该半持续调度的上行传输：
理解一：被上述RRC信令激活的第一个传输的空间关系根据与该上行传输属于同小区的被激活的BWP中最小编号的上行控制信道的空间方向确定，被上述RRC信令激活的除第一个传输以外的其他传输所依据的表示空间关系的参考信号与第一个传输所依据的表示空间关系的参考信号相同；
理解二：被上述RRC信令激活的第一个传输的空间关系根据与该上行传输属于同小区的被激活的BWP中最小编号的上行控制信道的空间方向确定，被上述RRC 信令激活的除第一个传输以外的其他传输所使用的空域滤波器与第一个传输所使用的空域滤波器相同；
理解三：被上述RRC信令激活的每个传输的空间关系与根据与该上行传输属于同小区的被激活的BWP中最小编号的上行控制信道的最近时隙的空间关系相同。
也就是说，在该变型例中，当上述配置条目被设为去使能时，以下的波束指示方法可以用于该PUSCH#1：
方法1：终端设备根据在激活的BWP中最小编号的PUCCH(与PUSCH#1传输同小区)的空间方向(如果存在的话)来确定被激活的第一个PUSCH#1的空间关系。如果PUCCH资源还没有被专用的RRC配置，该PUSCH#1将跟随PUCCH在专用RRC配置之前的空间方向，即与Msg 3的空间方向相同。在rrc-ConfiguredUplinkGrant被重配置之前，发送之后的(被激活的)PUSCH#1所依据的表示空间关系的参考信号与发送第一个(被激活的)PUSCH#1所依据的表示空间关系的参考信号相同。在方法1中，Type 1 PUSCH transmission的空间关系可以与PUCCH相同，同时传输PUSCH所依据的表示空间方向的参考信号在rrc-ConfiguredUplinkGrant被重配置之前始终不变，降低了系统复杂度。
方法2：终端设备根据在(与PUSCH#1传输同小区的)激活的BWP中最小编号的PUCCH的空间方向(如果存在的话)来确定被激活的第一个PUSCH#1的空间关系。如果PUCCH资源还没有被专用的RRC配置，该PUSCH#1将跟随PUCCH在专用RRC配置之前的空间方向，即与Msg 3的空间方向相同。在rrc-ConfiguredUplinkGrant被重配置之前，之后的被激活的PUSCH#1的空域滤波器将与第一个被激活的PUSCH#1的空域滤波器相同。在方法2中，Type 1 PUSCH transmission的空间关系可以与PUCCH相同，同时传输PUSCH所使用的空域滤波器在rrc-ConfiguredUplinkGrant被重配置之前始终不变，降低了系统复杂度。
方法3：在rrc-ConfiguredUplinkGrant被重配置之前，每个被激活的PUSCH的空间关系将基于(与PUSCH#1传输同小区的)被激活的BWP中最小编号的PUCCH的最近时隙的空间关系(如果存在的话)。如果PUCCH资源还没有被专用的RRC配置，发送该PUSCH#1的空域滤波器将与Msg 3的空域滤波器相同。在方法3中，Type 1 PUSCH transmission的空间关系可以被配置为与PUCCH相同，从而能够在波束方向经常发生变化的场景中，无需多次使用RRC重配置，减少了信令开销。
在本实施方式的另一个变型例中，还可以利用srs-ResourceIndicator中的一个字段来指示SRI是否存在，当根据上述字段的值确定SRI不存在时，终端设备可以根据前一变型例中的任意一种理解发送该半持续调度的上行传输。例如，将srs-ResourceIndicator中的一个codepoint，如“1111”等同为SRI不存在，当srs-ResourceIndicator设为“1111”时，前一变型例中的波束指示方法可以用于该PUSCH#1。
实施方式6：

理解三：被上述DCI激活的每个传输的空间关系与根据与该DCI属于同小区的BWP中最小编号的上行控制信道的最近时隙的空间关系相同。
下面以半持续调度的上行传输为Type 2 PUSCH transmission(简称为PUSCH#2)为例对本实施方式进行说明。
在本实施方式中，在上行传输中，在网络设备通过高层信令(如RRC信令)完成了半持续调度参数的配置以后，Type 2 PUSCH transmissions被CS-RNTI加扰的DCI format 0_0激活。则以下的波束指示方法可以用于该PUSCH#2：
方法1：终端设备根据在被激活的BWP中最小编号的PUCCH(与上述DCI同小区)的空间方向(如果存在的话)来确定被激活的第一个PUSCH#2的空间关系。如果PUCCH资源还没有被专用的RRC配置，该PUSCH#2将跟随PUCCH在专用RRC配置之前的空间方向，即与Msg 3的空间方向相同。在被(与上述DCI同小区 的)CS-RNTI加扰的DCI format 0_0重激活之前，发送之后的(被激活的)PUSCH#2所依据的表示空间关系的参考信号与发送第一个(被激活的)PUSCH#2所依据的表示空间关系的参考信号相同。在方法1中，发送PUSCH#2所依据的参考信号在DCI重激活之前始终不变，降低了系统复杂度。

方法3：在被(与上述DCI同小区的)CS-RNTI加扰的DCI format 0_0重激活之前，每个被激活的PUSCH#2的空间关系将基于激活的BWP中最小编号的PUCCH(与上述DCI同小区)的最近时隙的空间关系(如果存在的话)确定。如果PUCCH资源还没有被专用的RRC配置，发送该PUSCH#2的空域滤波器将与Msg 3的空域滤波器相同。在方法3中，PUSCH#2的空间关系与PUCCH相同，从而能够在波束方向经常发生变化的场景中完成动态波束切换，无需多次使用RRC重配置，减少了信令开销。

在本实施方式中，在网络设备通过高层信令(如RRC信令)完成了半持续调度参数的配置以后，对于基于PUCCH的半持续CSI上报，被MAC-CE信令激活。终端设备从原BWP(称为第一BWP)切换到其他BWP，这时原先被激活的半持续PUCCH(也即，承载半持续CSI上报的PUCCH)的传输暂停。当终端设备从其他BWP切换回原BWP时，该半持续PUCCH的传输将恢复。则以下的波束指示方法可以用于被该MAC-CE信令激活的、在终端设备切换回原BWP后恢复的、承载半持续CSI上报的PUCCH：
方法1：终端设备根据RRC配置的空间关系发送激活后的第一个PUCCH。在被MAC-CE信令重激活之前，发送第一个(被激活)的PUCCH所依据的表示空间关系的参考信号和发送之后的(被激活的)PUCCH所依据的表示空间关系的参考信号相同。在方法1中，发送PUCCH所依据的表示空间关系的参考信号在MAC-CE重激活之前始终不变，降低了系统复杂度。
方法2：终端设备根据RRC配置的空间关系发送激活后的第一个PUCCH。在被MAC-CE信令重激活之前，发送第一个(被激活的)PUCCH的空域滤波器与发送之后的(被激活的)PUCCH的空域滤波器相同。在方法2中，发送PUCCH的空域滤波器在MAC-CE重激活之前始终不变，降低了系统复杂度。
方法3：在MAC-CE信令重激活之前，每个被激活的PUCCH的空间关系将依据最近时隙的被激活的空间关系确定。如果该空间关系没有被激活，则根据预先设定的行为，如根据所配置的空间关系表中的第一个条目确定。在方法3中，发送PUCCH所依据的表示空间关系的参考信号会根据MAC-CE信令或是默认指示(依据所配置的空间关系表中的第一个条目)动态变化，从而能够在波束方向经常发生变化的场景中完成动态波束切换，无需多次MAC-CE重激活，减少了信令开销。
方法4：终端设备根据在原BWP上(暂停之前)最近一次发送该半持续PUCCH所依据的表示空间关系的参考信号发送所述第一个PUCCH。在被MAC-CE信令重激活之前，发送所述第一个PUCCH所依据的表示空间关系的参考信号和发送之后的PUCCH所依据的表示空间关系的参考信号相同。在方法4中，在终端设备切换回原BWP后，发送PUCCH所依据的表示空间关系的参考信号与切换前相同。保证了PUCCH的传输方向在BWP切换过程中的一致性。
方法5：终端设备根据在原BWP上(暂停之前)最近一次发送该半持续PUCCH所依据的表示空间关系的参考信号发送激活后的第一个PUCCH。在被MAC-CE信令重激活之前，发送所述第一个PUCCH的空域滤波器与发送之后的PUCCH的空域滤波器相同。在方法5中，在终端设备切换回原BWP后，发送PUCCH所使用的空域滤波器与切换前相同。保证了PUCCH传输方向在BWP切换过程中的一致性。
实施方式11：
在本实施方式中，上述至少一个传输为基于上行传输的周期性CSI上报，激活信令为RRC信令，则终端设备可以根据下面任意一种理解发送该上行传输：
理解一：被上述RRC信令激活的第一个传输根据RRC配置的控制信道的空间关系发送，被上述RRC信令激活的除第一个传输以外的其他传输所依据的表示空间关系的参考信号与第一个传输所依据的表示空间关系的参考信号相同；
理解二：被上述RRC信令激活的第一个传输根据RRC配置的控制信道的空间关系发送，被上述RRC信令激活的除第一个传输以外的其他传输所使用的空域滤波器与第一个传输所使用的空域滤波器相同；
理解三：被上述RRC信令激活的每个传输的空间关系与相关联的控制信道最近时隙的被应用的空间关系相同。
下面以基于上行传输的周期性CSI上报为基于PUCCH的周期性CSI上报为例对本实施方式进行说明。
在本实施方式中，在网络设备通过高层信令(如RRC信令)完成了调度参数的配置以后，RRC信令激活了基于PUCCH的周期性CSI上报，也即，对于基于PUCCH的周期性CSI上报开始。则以下的波束指示方法可以用于该PUCCH：
方法1：终端设备根据RRC配置的空间关系发送激活后的第一个PUCCH。在被相应的RRC信令重配置之前，发送第一个(被激活的)PUCCH所依据的表示空间关系的参考信号和发送之后的(被激活的)PUCCH所依据的表示空间关系的参考信号相同。在方法1中，发送PUCCH所依据的表示空间关系的参考信号在相应的RRC信令重配置之前始终不变，降低了系统复杂度。
方法2：终端设备根据RRC配置的空间关系发送激活后的第一个PUCCH。在被相应的RRC信令重配置之前，发送第一个(被激活的)PUCCH的空域滤波器与发送之后的(被激活的)PUCCH的空域滤波器相同。在方法2中，发送PUCCH的空域滤波器在相应的RRC信令重配置之前始终不变，降低了系统复杂度。
方法3：在相应的RRC信令重配置之前，每个被激活的PUCCH的空间关系根据相关联的控制信道最近时隙的被应用的空间关系确定。如果该空间关系没有被激活，则根据预先设定的行为，如根据所配置的空间关系表中的第一条目确定。在方法3中，发送PUCCH所依据的表示空间关系的参考信号会根据MAC-CE信令或是默认指示(依据所配置的空间关系的第一条目)动态变化，从而能够在波束方向经常发生变化的场景中完成动态波束切换，无需多次使用相应的RRC信令重配置，减少了信令开销。
在以上实施方式1-11中，仅从终端设备的角度对波束指示方法进行了说明，然而，终端设备和网络设备对波束指示的理解是一致的。
以上结合具体的实施方式(场景)对本实施例的波束指示方法进行了说明，本实施例并不以此作为限制，本实施例的波束指示方法还可以应用于其他场景，例如，激活信令是除DCI、MAC-CE、RRC以外的其他信令，再例如，被激活的传输是除半持续调度的下行传输、半持续调度的上行传输、基于上行传输的CSI以外的其他传输。并且，以上场景也可以根据具体的实施情况进行各种组合。
通过本实施例的方法，对于半持续调度或者周期性调度的传输，在激活信令和去激活信令或下一次激活信令之间，终端设备可以使用相同的空域滤波器或者传输假设，或者使用通过动态解读所述激活信令而确定的各自的空域滤波器或者传输假设，进行发送或接收，解决了在上述区间的波束指示模糊的问题。
