具体实施方式
为了能够更加详尽地了解本申请实施例的特点和技术内容，下面结合附图对本申请实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本申请实施例。
NTN采用卫星通信的方式向地面用户提供通信服务。与地面蜂窝网通信相比，卫星通信具有很多独特的优点。首先，卫星通信不受用户地域的限制，例如一般的陆地通信不能覆盖海洋、高山、或沙漠等无法搭设通信设备或由于人口稀少而不做通信覆盖的区域；而对于卫星通信来说，由于一颗卫星即可以覆盖较大面积的地面，并且卫星可以围绕地球做轨道运动，因此理论上地球上每一个角落都可以被卫星通信覆盖。其次，卫星通信有较高的社会价值。卫星通信在边远山区、贫穷落后的国家或地区都可以以较低的成本覆盖到，从而使这些地区的人们享受到先进的语音通信和移动互联网技术，有利于缩小与发达地区的数字鸿沟，促进这些地区的发展。再次，卫星通信距离远，且通信距离增大并不会明显增加通讯的成本；最后，卫星通信的稳定性高，不受自然灾害的限制。
通信卫星按照轨道高度的不同分为LEO卫星、中地球轨道(Medium-Earth Orbit，MEO)卫星、地球同步轨道(Geostationary Earth Orbit，GEO)卫星、和高椭圆轨道(High Elliptical Orbit，HEO)卫星等。下面分别对LEO和GEO进行简要说明。
LEO的轨道高度范围为500km至1500km，相应轨道周期约为1.5小时至2小时。终端设备之间单跳通信的信号传播延迟一般小于20ms。最大卫星可视时间20分钟。信号传播距离短，链路损耗少，对终端设备的发射功率要求不高。
GEO的轨道高度为35786km，围绕地球旋转周期为24小时。终端设备之间单跳通信的信号传播延迟一般为250ms。为了保证卫星的覆盖以及提升整个卫星通信系统的系统容量，卫星采用多波束覆盖地面，一颗卫星可以形成几十甚至数百个波束来覆盖地面；一个卫星波束可以覆盖直径几十至上百公里的地面区域。
在新无线(New Radio，NR)系统中，网络设备可以为终端设备配置DRX功能。使终端设备非连续地监听物理下行控制信道(Physical Downlink Control Channel，PDCCH)，进而达到终端设备省电的目的。每个媒体接入控制(Medium Access Control，MAC)实体有一个DRX配置；DRX的配置参数包括：
1)DRX持续定时器(DRX-onDuration Timer)，在一个DRX周期(Cycle)的开始终端设备醒 来的持续时间。
2)DRX时隙偏移(DRX-SlotOffset)，终端设备启动DRX-onDuration Timer的时延。
3)DRX去激活定时器(DRX-InactivityTimer)，当终端设备收到一个指示上行初传或者下行初传的PDCCH后，终端设备继续监听PDCCH的持续时间。
4)DRX下行重传定时器(DRX-RetransmissionTimerDL):终端设备监听指示下行重传调度的PDCCH的最长持续时间。除广播混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)进程之外的每个下行HARQ进程对应一个DRX–RetransmissionTimerDL。
5)DRX上行重传定时器(DRX-RetransmissionTimerUL):终端设备监听指示上行重传调度的PDCCH的最长持续时间。每个上行HARQ进程对应一个DRX-RetransmissionTimerUL。
6)DRX长周期起始偏移(DRX-LongCycleStartOffset)：用于配置长DTX周期(Long DRX cycle)，以及Long DRX cycle和短DRX周期(Short DRX Cycle)开始的子帧偏移。
7)DRX短周期(DRX-ShortCycle):为可选配置。
8)DRX短周期定时器(DRX-ShortCycleTimer):终端设备处于Short DRX cycle(并且没有接收到任何PDCCH)的持续时间，为可选配置。
9)DRX-HARQ-RTT-TimerDL:终端设备期望接收到指示下行调度的PDCCH需要的最少等待时间，除广播HARQ进程之外的每个下行HARQ进程对应一个DRX-HARQ-RTT-TimerDL；
10)DRX-HARQ-RTT-TimerUL:终端设备期望接收到指示上行调度的PDCCH需要的最少等待时间，每个上行HARQ进程对应一个drx-HARQ-RTT-TimerUL。
如果终端设备配置了DRX，则终端设备需要在DRX Active Time监听PDCCH。DRX Active Time包括如下几种情况：
1)下述5个定时器中的任何一个定时器正在运行：DRX-onDurationTimer、DRX-InactivityTimer、DRX–RetransmissionTimerDL、DRX-RetransmissionTimerUL以及ra-ContentionResolutionTimer。
2)在PUCCH上发送了调度请求(Scheduling Request，SR)并处于待处理(pending)状态。
3)在基于竞争的随机接入过程中，终端设备在成功接收到随机接入响应后还没有接收到小区无线网络临时标识(Cell Radio Network Temporary Identifier，C-RNTI)加扰的PDCCH指示的一次初始传输。
终端设备的DRX周期示意图，如图1所示，终端设备根据当前处于短DRX周期(Short DRX Cycle)或长DRX周期(Long DRX Cycle)，来决定启动drx-onDurationTimer的时间，具体规定如下：
1)如果终端设备当前处于Short DRX Cycle，并且当前子帧满足[(SFN×10)+subframe number]modulo(drx-ShortCycle)＝(drx-StartOffset)modulo(drx-ShortCycle)；或者
2)如果终端设备当前处于Long DRX Cycle，并且当前子帧满足[(SFN×10)+subframe number]modulo(drx-LongCycle)＝drx-StartOffset:
则在当前子帧开始的drx-SlotOffset个slot之后的时刻启动drx-onDurationTimer。
相关技术中，长DRX周期是默认配置的，短DRX周期是可选的配置；对于配置了短DRX周期的终端设备，长DRX周期与短DRX周期之间存在如下转换方式：
当满足以下任何一个条件时，终端设备使用短DRX周期：drx-InactivityTimer超时和终端设备接收到一个DRX Command MAC CE。
当满足以下任何一个条件时，终端设备使用长DRX周期：drx-ShortCycleTimer超时和终端设备接收到一个long DRX command MAC CE。
在NR系统中，为了支持多波束操作，NR系统采用了波束管理机制，用于初始接入、控制信道和数据信道等。
对于PDCCH，网络设备可以为终端设备在每个服务小区配置最多12个控制资源集(Control Resource Set)，同时为每个Control Resource Set配置一组传输配置指示(Transmission Configuration Indicator，TCI)状态(state)指示MAC CE指示终端设备激活一个Control Resource Set中的一个TCI state。PDCCH TCI state指示MAC CE的格式示意图，可以如图2所示，至少包括服务小区(Serving Cell，SC)标识(Identify，ID)、TCI state ID和CORESET ID。
终端设备在网络设备配置的PDCCH搜索空间上监听PDCCH。网络设备可终端设备的每个下行带宽部分(DownLink BandWidth Part，DL BWP)配置最多10个PDCCH搜索空间，每个PDCCH搜索空间对应一个Control Resource Set。终端设备在搜索空间对应的Control Resource Set的激活TCI state上接收PDCCH。
对于PDSCH使用的TCI state，可以通过调度该PDSCH传输的PDCCH指示。
终端设备通过PUCCH进行周期CSI上报；网络设备可以通过RRC信令为PUCCH配置一组空间关系，一组空间关系在同一个时刻只能有其中的一个空间关系处于激活状态。网络设备使用PUCCH空间关系激活去激活MAC CE指示终端设备激活一个PUCCH资源的其中一个空间关系。PUCCH空间关系激活去激活MAC CE的格式示意图，如图3所示，至少可以包括SC ID、BWP ID以及PUCCH资源ID。
相关技术中，对于配置了DRX的终端设备，终端设备只能在DRX active time进行周期CSI上报，网络设备也只能在DRX active time发送与波束管理相关的指示信息。
对于地面蜂窝网络，终端设备的移动性不高、波束变化较慢；而对于NTN中的非GEO场景，如LEO场景，由于卫星相对于地面高速移动，使得终端设备具有频繁切换波束的需求。如果终端设备在一段时间内都处于DRX inactive time，一方面，终端设备无法上报CSI，从而使网络设备无法获取终端设备在各波束方向上的信道状态；另一方面，网络设备在DRX inactive time也无法发送波束更新指示。
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、非授权频段上的NR(NR-based access to unlicensed spectrum，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)，以及车辆间(vehicle to vehicle，V2V)通信等，本申请实施例也可以应用于这些通信系统。

在一些实施例中，所述第一时间不包括DRX激活期。
在一些实施例中，所述第一时间可以包括：DRX去激活期和/或CSI测量上报激活期。
在一些实施例中，在所述第一时间包括所述DRX去激活期的情况下，所述终端设备在所述DRX去激活期进行CSI测量和/或CSI上报。
在另一些实施例中，在所述第一时间包括CSI测量上报激活期的情况下，所述终端设备在所述CSI测量上报激活期进行CSI测量和/或CSI上报。在该场景下，本申请实施例所述的波束管理方法还可以包括：
步骤S200，终端设备接收网络设备配置的第一定时器。
在一些实施例中，所述网络设备通过RRC信令或系统消息向所述终端设备配置第一定时器。
在一些实施例中，所述第一定时器运行的时间为所述CSI测量上报激活期；也可以理解为，所述第一定时器的运行期为所述CSI测量上报激活期。在所述CSI测量上报激活期，所述终端设备可以进行CSI测量和/或CSI上报。
针对第一定时器，在一些可选实施方式中，所述第一定时器的启动周期为短DRX周期，所述 第一定时器的启动时刻与DRX持续定时器的启动时刻相同。所述第一定时器的时长可以等于DRX持续定时器的时长，或者，所述第一定时器的时长由网络设备配置。所述第一定时器的启动状态可以与DRX持续定时器的启动状态无关，或者所述第一定时器的启动状态也可以与DRX持续定时器的启动状态相关。
其中，所述第一定时器的启动状态与DRX持续定时器的启动状态无关是指以short DRX cycle为周期，周期性的启动所述第一定时器。所述第一定时器的启动状态与DRX持续定时器的启动状态相关可以包括：若所述DRX持续定时器启动，则所述第一定时器不启动；或者，若所述DRX持续定时器不启动，则所述第一定时器启动。举例来说，以短DRX周期为例，在每个短DRX周期对应的drx-onDurationTimer的启动时刻点(无论当前终端设备是处于short DRX cycle还是Long DRX cycle)，如果终端设备不启动drx-onDurationTimer，则终端设备启动第一定时器；如果终端设备启动drx-onDurationTimer，则终端设备不启动第一定时器。
所述第一定时器启动，可以理解为所述第一定时器的状态为启动状态，且由终端设备启动所述第一定时器。所述第一定时器不启动，可以理解为所述第一定时器的状态为不启动状态或不运行状态，且终端设备不启动所述第一定时器。
针对第一定时器，在另一些可选实施方式中，所述第一定时器的启动周期和/或所述第一定时器的时长可以由网络设备配置。
在一些实施例中，本申请实施例提供的波束管理方法还可以包括：
步骤S202，终端设备接收PUCCH空间关系激活去激活准则。
在一些实施例中，所述终端设备接收网络设备发送的PUCCH空间关系激活去激活准则，所述PUCCH空间关系激活去激活准则用于终端设备激活和/或去激活PUCCH空间关系，以实现波束管理。可选地，所述PUCCH空间关系激活去激活准则可以携带于RRC信令中或系统消息中。
在一些实施例中，所述PUCCH空间关系激活去激活准则也可以以指示信息的形式体现，如终端设备接收网络设备发送的指示信息，所述指示信息用于终端设备确定PUCCH空间关系激活去激活准则。
在一些实施例中，所述PUCCH空间关系激活去激活准则可以包括：在所述第一时间，若当前激活的PUCCH空间关系对应的CSI测量结果小于第一阈值、且存在至少一个空间关系对应的CSI测量结果大于第二阈值，则CSI测量结果中最大值对应的空间关系为激活的PUCCH空间关系。其中，所述第一阈值和所述第二阈值均可以由网络设备配置，或者由协议约定；所述第一阈值小于所述第二阈值。因此，所述第一阈值和第二阈值可以用于终端设备在DRX去激活期，进行CSI上报时确定用于所述CSI上报的激活的PUCCH空间关系。
在一些实施例中，所述第一阈值可以为第一参考信号接收功率(Reference Signal Received Power，RSRP)阈值，所述第二阈值可以为RSRP阈值；相应的，所述CSI测量结果可以为RSRP。
在一些实施例中，本申请实施例提供的波束管理方法还可以包括：

针对终端设备进行CSI上报所使用的PUCCH，在一些实施例中，若终端设备处于DRX激活期，且终端设备接收到PUCCH空间关系激活去激活MAC CE，则终端设备基于所述PUCCH空间关系激活去激活MAC CE指示确定PUCCH对应的空间关系。否则，终端设备维持当前的PUCCH空间关系不变。
针对终端设备进行CSI上报所使用的PUCCH，在另一些实施例中，若终端设备处于DRX去激活期，若所述终端设备在当前激活的PUCCH空间关系对应的CSI测量结果小于第一RSRP阈值、且存在至少一个空间关系对应的CSI测量结果大于第二RSRP阈值，则所述终端设备将所述CSI测量结果中最大值对应的空间关系作为激活的PUCCH的空间关系；否则，所述终端设备保持所述当前激活的PUCCH空间关系。所述第一RSRP阈值小于所述第二RSRP阈值。
步骤S404，在终端设备由DRX去激活期进入DRX激活期的情况下，终端设备监听PDCCH。
在一些实施例中，终端设备由DRX去激活期进入DRX激活期可以是终端设备在DRX去激活期发送了调度请求(Scheduling Request，SR)并处于等待(pending)状态；终端设备由DRX去激活期进入DRX激活期也可以是终端设备启动了DRX持续定时器。
针对终端设备监听PDCCH，如果终端设备在最近一次DRX inactive time改变了所述第一周期CSI上报的激活的PUCCH空间关系，则终端设备在一个默认的PDCCH搜索空间使用与所述激活的 PUCCH空间相同或相关的SSB或者CSI-RS作为所述默认的PDCCH搜索空间对应的ControlResourceSet激活的TCI state监听PDCCH。所述默认的PDCCH搜索空间可以由网络配置，所述默认的PDCCH搜索空间对应的ControlResourceSet没有配置TCI state列表。

在一些实施例中，终端设备基于上述两种方式监听PDCCH的过程中，若所述终端设备接收到针对服务小区的至少一个ControlResourceSet的PDCCH TCI state指示MAC CE，则终端设备在当前激活的下行BWP对应的除默认的PDCCH搜索空间以外的PDCCH搜索空间上使用该PDCCH搜索空间对应的ControlResourceSet的激活TCI state监听PDCCH。
在另一些实施例中，终端设备基于上述两种方式监听PDCCH的过程中，网络设备为终端设备配置第一时长，如果终端设备在所述第一时长内没有收到针对该服务小区的至少一个ControlResourceSet的PDCCH TCI state指示MAC CE，则在达到所述第一时长后，终端设备在当前激活的下行BWP对应的除默认的PDCCH搜索空间以外的PDCCH搜索空间上使用该PDCCH搜索空间对应的ControlResourceSet的激活TCI state监听PDCCH。
下面基于图8所示的终端设备监听PDCCH的一种可选示意图，对图7所示的波束管理方法进行详细说明。
若网络设备配置第一周期CSI上报配置，所述第一周期CSI上报配置所使用的PUCCH对应的空间关系列表为SSB1、SSB2、SSB3和SSB4。网络设备在一个DL BWP上配置一个PDCCH搜索空间1，所述PDCCH搜索空间1的ControlResourceSet对应的TCI state列表为SSB1、SSB 2、SSB3和SSB4。以短DRX周期为例，在第一DRX周期，终端接收到PDCCH TCI state指示MAC CE指示激活SSB1，则终端设备在DRX激活期在SSB1上监听PDCCH，UE接收到PUCCH空间关系激活去激活MAC CE指示激活空间关系SSB1，则UE在SSB1上传输PUCCH。并且，在第一DRX周期内的DRX去激活期，终端设备仍旧在SSB1上传输PUCCH。在第二DRX周期，在DRX激活期，终端在接收到PDCCH TCI state指示MAC CE之前，终端设备在PDCCH搜索空间1的控制资源集对应的SSB1、SSB2、SSB3和SSB4上监听PDCCH；终端在接收到PDCCH TCI state指示MAC CE指示激活SSB2之后，终端设备在PDCCH搜索空间1的控制资源集对应的SSB2上监听PDCCH。终端在激活期内没有接收到PUCCH空间关系激活去激活MAC CE，则终端设备在激活的PUCCH空间关系SSB2上传输PUCCH。在第二DRX周期内的DRX去激活期，终端设备根据CSI测量结果(如测量结果小于第一RSRP阈值、且大于第二RSRP阈值)将CSI测量结果中RSRP最高的空间关系SSB3作为激活的PUCCH空间关系，并在SSB3上传输PUCCH。在第三DRX周期，由于在第二DRX周期，终端设备改变了激活的PUCCH空间关系，因此在DRX激活期，终端设备在与默认的PDCCH搜索空间的控制资源集对应的空间关系对应的SSB3上监听PDCCH、以及传输PUCCH；当终端接收到PDCCH TCI state指示MAC CE指示激活SSB3，终端设备在PDCCH搜索空间1的控制资源集对应的空间关系对应的SSB3上监听PDCCH。在第三DRX周期的DRX去激活期，终端设备在SSB3上传输PUCCH。
下面针对第一时间为CSI测量上报激活期的情况，本申请实施例中波束管理方法的一种详细处理流程，如图9所示，包括以下步骤：

在一些实施例中，所述测量配置信息携带于RRC信令中。
在一些实施例中，所述测量配置信息可以包括下述中的至少一种参数：DRX相关参数、CSI测量上报相关参数和PDCCH搜索空间相关参数；其中，

c.终端设备可以在CSI测量上报激活期基于所述第一周期CSI上报配置进行第一周期CSI上报时，终端设备可以基于网络设备配置的PUCCH空间关系切换准及CSI测量结果改变用于所述第一周期CSI上报的激活的PUCCH空间关系。
3)对于所述第一周期CSI上报配置对应的PUCCH资源，网络设备配置第一RSRP阈值和第二RSRP阈值，所述第一RSRP阈值和第二RSRP阈值用于终端设备在DRXinactive time，基于所述第一周期CSI上报配置进行第一周期CSI上报时改变用于所述第一周期CSI上报的激活的PUCCH空间关系。所述第一RSRP阈值小于第二RSRP阈值。
4)对于每个下行BWP，配置至少一个PDCCH搜索空间。
5)配置第一定时器，当所述第一定时器正在运行时，终端设备处于CSI测量上报激活期。
针对第一定时器，在一些可选实施方式中，所述第一定时器的启动周期为短DRX周期，所述第一定时器的启动时刻与DRX持续定时器的启动时刻相同。所述第一定时器的时长可以等于DRX持续定时器的时长，或者，所述第一定时器的时长由网络设备配置。所述第一定时器的启动状态可以与DRX持续定时器的启动状态无关，或者所述第一定时器的启动状态也可以与DRX持续定时器的启动状态相关。其中，所述第一定时器的启动状态与DRX持续定时器的启动状态相关可以包括：若所述DRX持续定时器启动，则所述第一定时器不启动；或者，若所述DRX持续定时器不启动，则所述第一定时器启动。所述第一定时器启动，可以理解为所述第一定时器的状态为启动状态，且由终端设备启动所述第一定时器。所述第一定时器不启动，可以理解为所述第一定时器的状态为不启动状态或不运行状态，且终端设备不启动所述第一定时器。举例来说，以短DRX周期为例，在每个短DRX周期对应的drx-onDurationTimer的启动时刻点(无论当前终端设备是处于short DRX cycle还是Long DRX cycle)，如果终端设备不启动drx-onDurationTimer，则终端设备启动第一定时器；如果终端设备启动drx-onDurationTimer，则终端设备不启动第一定时器。
所述第一定时器启动，可以理解为所述第一定时器的状态为启动状态，且由终端设备启动所述第一定时器。所述第一定时器不启动，可以理解为所述第一定时器的状态为不启动状态或不运行状态，且终端设备不启动所述第一定时器。
针对第一定时器，在另一些可选实施方式中，所述第一定时器的启动周期和/或所述第一定时器的时长可以由网络设备配置。
步骤S502，终端设备在CSI测量上报激活期，在第一周期CSI上报配置对应的CSI测量时机执行CSI测量。

步骤S503，终端设备基于所述第一周期CSI上报配置，在DRX激活期和CSI测量上报激活期利用所述第一周期CSI上报配置对应的PUCCH进行CSI上报。
针对终端设备进行CSI上报所使用的PUCCH，在一些实施例中，若终端设备处于DRX激活期，且终端设备接收到PUCCH空间关系激活去激活MAC CE，则终端设备基于所述PUCCH空间关系激活去激活MAC CE指示确定PUCCH对应的空间关系。否则，终端设备维持当前的PUCCH空间关系不变。
针对终端设备进行CSI上报所使用的PUCCH，在另一些实施例中，若终端设备处于CSI测量上报激活期，若所述终端设备在当前激活的PUCCH空间关系对应的CSI测量结果小于第一RSRP阈值、且存在至少一个空间关系对应的CSI测量结果大于第二RSRP阈值，则所述终端设备将所述CSI测量结果中最大值对应的空间关系作为激活的PUCCH的空间关系；否则，所述终端设备保持所述当前激活的PUCCH空间关系。所述第一RSRP阈值小于所述第二RSRP阈值。
步骤S504，在终端设备由DRX去激活期进入DRX激活期的情况下，终端设备监听PDCCH。
在一些实施例中，终端设备由DRX去激活期进入DRX激活期可以是终端设备在DRX去激活期发送了SR并处于pending状态；终端设备由DRX去激活期进入DRX激活期也可以是终端设备激动了DRX持续定时器。
针对终端设备监听PDCCH，如果终端设备在最近一次DRX inactive time改变了所述第一周期CSI上报的激活的PUCCH空间关系，则终端设备在一个默认的PDCCH搜索空间使用与所述激活的PUCCH空间相同或相关的SSB或者CSI-RS作为所述默认的PDCCH搜索空间对应的ControlResourceSet激活的TCI state监听PDCCH。所述默认的PDCCH搜索空间可以由网络配置，所述默认的PDCCH搜索空间对应的ControlResourceSet没有配置TCI state列表。
针对终端设备监听PDCCH，如果终端设备在最近一次DRX inactive time没有改变所述第一周期CSI上报的激活的PUCCH空间关系，则终端设备在当前激活的下行BWP对应的除默认的PDCCH搜索空间以外的PDCCH搜索空间上使用该PDCCH搜索空间对应的ControlResourceSet的所有TCI state监听PDCCH。
在一些实施例中，终端设备基于上述两种方式监听PDCCH的过程中，若所述终端设备接收到针对服务小区的至少一个ControlResourceSet的PDCCH TCI state指示MAC CE，则终端设备在当前激活的下行BWP对应的除默认的PDCCH搜索空间以外的PDCCH搜索空间上使用该PDCCH搜索空间对应的ControlResourceSet的激活TCI state监听PDCCH。
在另一些实施例中，终端设备基于上述两种方式监听PDCCH的过程中，网络设备为终端设备配置第一时长，如果终端设备在所述第一时长内没有收到针对该服务小区的至少一个ControlResourceSet的PDCCH TCI state指示MAC CE，则在达到所述第一时长后，终端设备在当前激活的下行BWP对应的除默认的PDCCH搜索空间以外的PDCCH搜索空间上使用该PDCCH搜索空间对应的ControlResourceSet的激活TCI state监听PDCCH。
下面基于图10所示的终端设备监听PDCCH的另一种可选示意图，对图9所示的波束管理方法进行详细说明。
若网络设备配置第一周期CSI上报配置，所述第一周期CSI上报配置所使用的PUCCH对应的空间关系列表为SSB1、SSB2、SSB3和SSB4。网络设备在一个DL BWP上配置一个PDCCH搜索空间1，所述PDCCH搜索空间1的ControlResourceSet对应的TCI state列表为SSB1、SSB 2、SSB3和SSB4。以长DRX周期为例，在第一DRX周期，在第一DRX周期，PUCCH空间关系激活去激活MAC CE指示激活空间关系SSB1，则终端设备在SSB1上传输PUCCH。并且，在第一DRX周期内的DRX去激活期，终端设备仍旧在SSB1上传输PUCCH。在第二DRX周期，由于在上一个非DRX激活期，未改变激活的PUCCH空间关系，则在DRX激活期，终端设备在PDCCH搜索空间1的控制资源集对应的SSB1、SSB2、SSB3和SSB4上监听PDCCH；当终端接收到PDCCH TCI state指示MAC CE指示激活SSB2，则终端设备在PDCCH搜索空间1的控制资源集对应的SSB2上监听PDCCH。终端设备在激活的空间关系SSB2上传输PUCCH。在第二DRX周期内的第一个CSI测量上报激活期，终端设备在SSB1上传输PUCCH，在第二DRX周期内的第二个CSI测量上报激活期，终端设备基于SCI测量结果将激活的PUCCH空间关系更改为SSB3，则终端设备在SSB3上传输PUCCH，在第二DRX周期内的第三个CSI测量上报激活期，终端设备在SSB3上传输PUCCH。在第三DRX周期，由于在上一个非DRX激活期，改变了激活的PUCCH空间关系，则在DRX激活期，终端设备在默认的PDCCH搜索空间的控制资源集对应的SSB3(PDCCH搜索空间1的控制资源集的激活TCI state)上监听PDCCH，当终端接收到PDCCH TCI state指示MAC CE指示激活SSB3，终端设备在PDCCH搜索空间1的控制资源集对应的SSB3上监听PDCCH。
本申请各实施例中，终端设备在DRX非激活期或者CSI测量上报激活期等非DRX激活期进行CSI测量和/或CSI上报；由于DRX非激活期或CSI测量上报激活期持续额时间较DRX激活期的时间更长，因此终端设备具有更多的CSI测量和/或CSI上报机会；使得在终端设备具有频繁切换波束需求的场景，如LEO场景，终端设备能够及时的向网络设备上报不同波束方向上的信道状态，网络设备也能够在除DRX激活期以外的时间具有更多机会向终端设备发送与波束相关的指示信息，以便进行有效的波束管理。
应理解，在本申请的各种实施例中，上述各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定。
