<第一实施例>
图1示出了根据本申请的一个实施例的用于无线通信的电子设备100的功能模块框图，如图1所示，电子设备100包括：确定单元101，被配置为确定发生物理层波束管理事件；以及执行单元102，被配置为执行UE发起的波束管理过程。
其中，确定单元101和执行单元102可以由一个或多个处理电路实现，该处理电路例如可以实现为芯片、处理器。并且，应该理解，图1中所示的电子设备中的各个功能单元仅是根据其所实现的具体功能而划分的逻辑模块，而不是用于限制具体的实现方式。这同样适用于随后要描述的其他电子设备的示例。
电子设备100例如可以设置在UE侧或者可通信地连接到UE。这里，还应指出，电子设备100可以以芯片级来实现，或者也可以以设备级来实现。例如，电子设备100可以工作为UE本身，并且还可以包括诸如存储器、收发器(图中未示出)等外部设备。存储器可以用于存储用户设备实现各种功能需要执行的程序和相关数据信息。收发器可以包括一个或多个通信接口以支持与不同设备(例如，基站、其他UE等等)间的通信，这里不具体限制收发器的实现形式。
例如，确定单元101可以基于UE对参考信号的测量来确定发生了物理层(L1)波束管理(beam management，BM)事件。具体地，确 定单元101可以在UE所测量的参考信号的质量下降到预定程度以下或者相当于先前的测量值下降了预定数值(比如9dB或12dB等)时，确定发生了物理层BM事件。
或者，确定单元101也可以利用UE上的传感器来检测到UE的移动或朝向的变化，初步确定之前的波束可能不再适用，从而确定发生物理层BM事件。
在确定单元101确定发生物理层BM事件的情况下，执行单元102执行UE发起的波束管理过程。在本公开中，UE发起的也可以被称为UE触发的或UE初始化的，这些表述均代表了类似的含义，即UE在波束管理过程中起到主动的作用。
示例性地，UE发起的波束管理过程包括如下中的任意一个或多个：UE发起的波束扫描，UE发起的波束上报，UE发起的波束激活，UE发起的波束选择。下面将分别描述UE发起的各个波束管理过程的示例。
UE发起的波束扫描
在UE发起的波束扫描的情况下，UE通过主动请求网络侧执行或允许执行非周期波束扫描，来寻找合适的下行或上行发射波束。本公开中的网络侧例如为基站。例如，执行单元102可以通过上行控制信息(Uplink Control Information，UCI)或MAC CE来请求网络侧触发UE发起的波束扫描。UCI可以包含在物理上行控制信道(Physical Uplink Control Channel，PUCCH)或物理上行共享信道(Physical Uplink Shared Channel，PUSCH)中。MAC CE可以包含在PUSCH中。
执行单元102可以通过UCI或MAC CE来请求网络侧触发UE发起的下行波束扫描。在执行单元102通过UCI包括用于触发下行波束扫描的信息的情况下，该UCI包括指示激活状态的CSI-AperiodicTriggerState的信息，即，该UCI指向一个激活状态的CSI-AperiodicTriggerState的非周期CSI-RS资源集合。该CSI-AperiodicTriggerState例如是由UE建议的。随后，网络侧通过下行控制信息(Downlink Control Information，DCI)来触发该非周期的CSI-RS波束扫描。
在执行单元102通过MAC CE包括用于触发下行波束扫描的信息的情况下，该MAC CE可以包括指示激活状态的或非激活状态的CSI-AperiodicTriggerState的信息。即，该MAC CE可以指向一个激活 状态的CSI-AperiodicTriggerState的非周期CSI-RS资源集合，也可以指向一个非激活状态的CSI-AperiodicTriggerState的非周期CSI-RS资源集合。在MAC CE所指向的CSI-AperiodicTriggerState处于非激活状态的情况下，网络侧将该CSI-AperiodicTriggerState激活并且认为UE也已经将该CSI-AperiodicTriggerState激活。随后，网络侧通过DCI来触发该非周期的CSI-RS波束扫描。在MAC CE所指向的CSI-AperiodicTriggerState处于激活状态的情况下，网络侧通过DCI来触发该非周期的CSI-RS波束扫描。
其中，在CSI-RS资源集合的参数Repetition为打开(ON)的时候，表示将在空间上重复传输CSI-RS资源，其目的是为了使UE找到合适的接收波束，即，UE进行接收波束扫描。在这种情况下，UE可以不向网络侧报告自己找到的合适的波束。
相反，在CSI-RS资源集合的参数Repetition为关闭(OFF)的时候，表示该资源集合中的CSI-RS资源使用不同的发射波束，其目的是为了找到合适的下行发射波束。在这种情况下，UE需要向网络侧上报所找到的合适的波束。
为了便于理解，图2示出了UE发起的下行波束扫描的过程的示例的示意图。首先，UE检测到发生物理层BM事件，然后通过UCI或MAC CE来请求网络侧触发非周期CSI-RS波束扫描，其中，UCI或MAC CE中包括UE推荐的CSI-AperiodicTriggerState的信息。接着，网络侧通过DCI来动态触发非周期CSI-RS波束扫描，该非周期CSI-RS波束扫描将基于上述CSI-AperiodicTriggerState所指向的非周期CSI-RS资源集合。图2中的两个虚线框分别代表CSI-RS资源集合的参数Repetition为打开或关闭时的两种情形，在必要的情况下，例如，在Repetition为关闭的情况下，UE向网络侧上报所找到的合适的波束的信息。
另一方面，执行单元102可以通过UCI或MAC CE来请求网络侧触发UE发起的上行波束扫描。例如，在UE发现自己的探测参考信号(Sounding Reference Signal，SRS)的发射波束可能不再适用的情况下，UE可以发起基于SRS的上行波束扫描过程。具体地，UCI或MAC CE可以包括aperiodicSRS-ResourceTrigger参数作为用于触发上行波束扫描的信息。
由于SRS的扫描波束是由UE来发送的，而一般而言UE无法自行决定是否占用上行资源来发送SRS，因此该过程需要网络侧进行确认，即，网络侧指示是否同意UE发送该非周期SRS。相应地，执行单元102还被配置为从网络侧获取网络侧对于上行波束扫描的确认。
图3示出了UE发起的上行波束扫描的过程的示例的示意图。首先，UE检测到发生物理层BM事件，然后通过UCI或MAC CE来请求网络侧触发非周期SRS波束扫描，其中，UCI或MAC CE中包括UE推荐的aperiodicSRS-ResourceTrigger的信息。接着，网络侧通过DCI来动态确认UE推荐的非周期SRS波束扫描，UE接收到该确认后执行非周期SRS波束扫描。然后，网络侧基于扫描结果对上行波束进行更新。
应该理解，以上描述的UE发起的波束扫描的过程和信令仅是示例性的，而非限制性的，在实际应用中可以根据具体需求进行适应性的修改。
UE发起的波束上报
在该情况下，执行单元102可以被配置为对UE接收到的参考信号进行测量，并基于测量结果执行UE发起的波束上报。
参考信号可以包括以下中的任意一个或多个：同步信号块(Synchronization Signal Block，SSB)、信道状态信息参考信号(CSI-RS)、解调参考信号(Demodulation Reference Signal，DMRS)。
其中，SSB和CSI-RS可以被认为是基于主动式的波束扫描的。这是因为，在NR***中，基站触发的主动式波束扫描和上报过程往往是在对UE进行PDSCH传输之前的，即，波束扫描过程是为后续的控制信道和数据信道的传输来服务的(可以称之为prior PDSCH的测量和上报)。
而DMRS可以被认为是基于被动式的波束检测的。这是因为，当UE完成了下行控制信道和下行数据信道的检测时，UE也完成了对该信道的DMRS的测量。因此，在执行UE发起的波束上报的情况下，也可以基于DMRS的测量结果进行上报。应该理解，基于DMRS的测量结果上报不仅可以应用于根据本公开的UE发起的上报的情形，也可以应用于网络侧发起的上报的情形。
对于控制信道而言，UE可以对每一个控制资源集合(Control Resource Set，CORESET)的一个或两个波束方向的DMRS进行测量。对于数据信道而言，UE可以最多对8个传输配置指示(Transmission Configuration Indicator，TCI)状态所指示的波束方向的DMRS进行测量，当然每次PDSCH传输往往对应着一个或两个TCI状态，如图4和图5所示。需要说明的是，只有当两个TRP对UE进行传输时，才会使用两个TCI状态；在一个TRP对UE进行传输时，只使用一个TCI状态。
UE可以测量DMRS的物理层参考信号接收功率(L1-RSRP)或物理层信干噪比(L1-SINR)。例如，DMRS的L1-RSRP被定义为在PDSCH或PDCCH情况下所考虑的频率带宽内承载被配置用于PDSCH或PDCCH的DMRS的天线端口的资源单元的功率贡献(单位为W)上的线性平均。DMRS的L1-SINR被定义为承载DMRS的资源单元的功率贡献(单位为W)上的线性平均除以噪声和干扰功率贡献(单位为W)的线性平均。如果DMRS的L1-SINR用于具有专用干扰测量资源的L1-SINR报告，则可以在由高层指示的资源上测量干扰和噪声。否则，可以在相同的频率带宽内在承载DMRS的资源单元上测量干扰和噪声。
此外，UE在对参考信号对应的波束的RSRP进行测量之后，可以通过计算该波束的发送功率与RSRP之间的差来获得波束功率的衰减量，从而确定信道质量的优劣。例如，波束功率的衰减量越小，则相应波束在该信道中的质量就越好。因此，为了公平地比较各个波束的性能，UE需要知道各个波束的发送功率。
例如，SSB的发送功率由网络侧通过无线资源控制(RRC)信令配置给UE，CSI-RS的功率由网络侧通过CSI-RS/SSB的功率比值通知UE，且DMRS的功率由网络侧通过DMRS/CSI-RS的功率比值通知UE。相应的信令如图6所示。
其中，powerControlOffset表示以dB为单位的PDSCH资源单元相对于NZP CSI-RS资源单元的功率偏移值，即DMRS/CSI-RS的功率比值。powerControlOffsetSS表示以dB为单位的NZP CSI-RS资源单元相对于辅同步信号(SSS)资源单元的功率偏移值，即CSI-RS/SSB的功率比值。
基于此，在UE执行了对DMRS对应的波束的测量之后，可以与基于CSI-RS和基于SSB的波束测量结果进行比较。例如，UE可以测量下行波束A的DM-RSRP，下行波束B的SS-RSRP和下行波束C的CSI-RSRP，并进行比较。
在UE测量的参考信号包括DMRS的情况下，执行单元102被配置为上报如下之一：与DMRS对应的TCI状态标识(ID)；与DMRS对应的TCI状态中包括的CSI-RS或SSB的ID。
由于DMRS本身没有资源ID，因此UE可以借助于与该DMRS对应的TCI状态相关的信息。
图7A示出了上报与DMRS对应的TCI状态中包括的CSI-RS或SSB的ID的一个示例。其中，第一栏是信道状态信息(CSI)报告编号，第二栏是CSI字段。每个CSI报告中可以包括一个或多个条目，最多例如为4个，图7A示出了这种情况。在图7A的示例中，上报与DMRS相关联的TCI状态中的CSI-RS资源指示(CSI-RS Resource Indicator，CRI)或SSB资源指示(SSB Resource Indicator，SSBRI)，以及对应的DMRS的RSRP。其中，第一个DMRS的RSRP为测量的RSRP的绝对值DM-RSRP#1，其他DMRS的RSRP为相对于该DM-RSRP#1的差分值。
图7B示出了上报与DMRS对应的TCI状态ID的一个示例。与图7A类似，第一栏是CSI报告编号，第二栏是CSI字段。每个CSI报告中可以包括一个或多个条目，最多例如为4个，图7B示出了这种情况。在图7B的示例中，上报与DMRS相关联的TCI状态ID以及对应的DMRS的RSRP。其中，第一个DMRS的RSRP为测量的RSRP的绝对值DM-RSRP#1，其他DMRS的RSRP为相对于该DM-RSRP#1的差分值。这样可以更加明确地指示UE更适合的TCI状态。在UE的上报内容可以作为UE自动激活或自动选择的波束的情况下，TCI状态是更直接的选项。
以上的示例给出了UE上报4个波束的情形，网络侧可以从4个波束中选择1个或2个来使用，但是这并不是限制性的。UE也可以仅上报1个波束(例如，对应于单TRP)或2个(例如，对应于多TRP)波束，这时网络侧不需要选择，而是可以直接使用上报的波束。
UE发起的波束激活或波束选择
由于UE发起的波束激活和波束选择具有相似的特性，因此一起进行描述。例如，对于波束变化相对静态的控制信道或信号，NR***往往使用波束激活的概念；对于波束变化相对动态的数据信道，NR***往往使用波束选择的概念，即从多个激活的波束中选择一个最合适的波束来使用。
另外，虽然这里对UE发起的波束激活或波束选择进行了单独的描述，但是，UE发起的波束上报和波束激活或选择可以是同一个过程，即UE在上报的过程中就将某些上报的波束进行激活，或者将UE的选择告知NW。即，两者可以是共同的信令过程，也可以是独立的信令过程。这都不是限制性的。
执行单元102被配置为在UE发起的波束激活或UE发起的波束选择中向网络侧发送UE建议的波束的信息。即，UE可以向网络侧推荐哪些上行或下行波束应该被激活或选择。例如，执行单元102可以通过UCI或MAC CE来进行发送。
此外，执行单元102还可以从网络侧获取指示UE从中进行建议的波束的范围的信息，即，网络侧提前设定一个范围，执行单元102在该范围内建议可以激活或选择的波束。
以下行波束的激活和选择为例，例如，网络侧提前配置了波束#1、波束#3、波束#5和波束#8这四个波束，UE将只能从这四个波束中来激活或选择一个或多个波束。通过将UE自主选择或激活的波束限定在网络侧配置或者指定的范围内，可以缩小UE上报的波束的范围，从而减少UE上行的信令开销。
另外，执行单元102可以通过MAC CE来接收网络侧对于范围调整的信息。即，在网络侧配置的波束范围发生变化时，网络侧可以通过MAC CE来调整该范围，例如，网络侧向UE发送如下MAC CE：其中包含波束#2、波束#4、波束#5和波束#9，这样可以覆盖之前配置的一组波束，从而动态地调整了UE自主波束激活和选择的范围。
示例性地，所发送的UE建议的波束的信息可以包括能够用于上行波束和下行波束两者的统一TCI状态。这里，UE激活或选择的Rel.17统一TCI状态，有别于传统的Rel.15/16中定义的TCI状态。首先，统 一TCI状态不但可以服务于下行传输，也可以服务于上行传输，甚至一个统一TCI状态可以同时服务于上行和下行传输。从功能性的角度来说，Rel.15/16TCI状态和Rel.17统一TCI状态，为NR***提供了不同的功能。
或者，上行波束的信息包括TCI状态，下行波束的信息包括空间关系信息(spatial relation information，SRI)。
下面分别针对下行信道和信号与上行信道和信号来描述UE发起的波束激活或选择的示例。
对于下行信道和信号，例如，对于PDCCH，UE可以为每一个CORESET激活1个TCI状态(对于单TRP)或2个TCI状态(对多TRP)，因为PDCCH的波束变化频率较PDSCH的波束慢，可以仅使用UE发起的波束激活；对于每个BWP的PDSCH，UE可以自主激活8个或者更多(比如16个)TCI状态，当UE对适合的波束比较确信时，UE也可以选择1个TCI状态(对于单TRP)或2个TCI状态(对多TRP)，即，可以使用UE发起的波束激活或波束选择；对于周期、半静态以及非周期的CSI-RS资源，UE可以为每一个CSI-RS资源激活或选择一个合适的TCI状态。
对于上行信道和信号，例如，对于上行的PUCCH资源，UE可以激活1个TCI状态(对于单TRP)或2个TCI状态(对多TRP)，或者1个SRI(对于单TRP)或2个SRI(对多TRP)；对于每个BWP的PUSCH，UE可以激活8个或者更多(比如16个)TCI状态，当UE对适合的波束比较确信时，UE也可以选择1个TCI状态(对于单TRP)或2个TCI状态(对多TRP)即，可以使用UE发起的波束激活或波束选择；对于上行的周期性的、半静态的以及非周期的SRS资源，UE可以为每一个SRS资源激活或选择一个合适的TCI状态或SRI。
另外，当UE被配置了多个分量载波、即采用载波聚合时，有些分量载波(component carrier，CC)可以使用相同的波束对进行通信。即，当UE激活或选择一个波束时，比如某一个特定的TCI状态，该TCI状态所包含的CSI-RS或SSB除了在当前的服务小区的CC上适用外，在其他的小区的CC上也同样适用，因此可以进行跨CC的UE发起的波束激活或波束选择。
具体地，执行单元102还可以被配置为从网络侧接收分量载波的列表，UE建议的波束适用于列表中的各个分量载波。即，能够适用建议的波束的多个CC是网络侧通过一个CC列表提前配置的。
网络侧对于UE发起的波束激活或波束选择，可以进行反馈，也可以不进行反馈，下面将参照图8至图10分别描述相关信令的三种示意性示例。如前所述，执行单元102可以通过UCI或MAC CE来发送UE建议的波束的信息。
如图8所示，UE从网络侧接收针对该发送的确认(ACK)或未确认(NACK)消息。即，网络侧通过DCI来发送关于承载UCI或MAC CE的PUSCH的隐式的ACK或NACK。在该示例中，执行单元102在从网络侧接收到ACK消息的情况下，确定网络侧正确接收并认可UE建议的波束。即，ACK表示网络侧正确接收到PUSCH并且认可(或确认)PUSCH所承载的UCI或MAC CE的内容、即波束激活或选择的信息。在这种情况下，经过一段时间(可以以符号为单位或者以ms为单位来测量)后，所建议的波束生效。反之，如果执行单元102从网络侧接收到NACK消息，则说明网络侧没有正确接收到PUSCH或者不认可UE建议的波束，在这种情况下，所建议的波束不能生效。
作为另一个示例，如图9所示，在网络侧正确接收PUSCH的情况下，通过DCI发送隐式的ACK，并且网络侧将使用另外发送的DCI来指示UCI或MAC CE中的UE激活或选择的波束得到了网络侧的确认。如果UE在预定时间窗口(即，图中所标出的一段时间)内没有收到该另外发送的DCI，则认为其激活或选择的波束没有得到网络侧的认可，即，UE自主激活或选择的波束无效，仍然使用旧的波束。反之，如果UE在预定时间窗口内收到该另外发送的DCI，则认为其激活或选择的波束得到了网络侧的认可，从而在预定时间窗口之后，所建议的波束生效。在该示例中，执行单元102被配置为在从网络侧接收到ACK消息并且在预定时间窗口内接收到另外的指示认可的DCI的情况下，确定网络侧正确接收并认可UE建议的波束。
作为又一个示例，如图10所示，在网络侧正确接收PUSCH的情况下，通过DCI发送隐式的ACK，如果网络侧认可UE建议的波束，则接下来网络侧在预定时间窗口内保持静默，经过一段时间后，UE建议的波束生效；而如果网络侧不认可UE建议的波束，则通过另外的DCI来改 写UE建议的波束(图10中所示的情形)，经过一段时间后，网络侧改写的波束生效。在该示例中，执行单元102在从网络侧接收到ACK消息并且在预定时间窗口内未接收到另外的DCI的情况下，确定网络侧正确接收并认可UE建议的波束。这样可以减小信令开销，同时保证网络侧和UE对于激活或选择波束的理解在相同的时刻保持一致。
此外，执行单元102还可以被配置为从网络侧接收是否启用UE发起的波束管理功能的指示，例如，执行单元102可以经由RRC信令来接收该指示。执行单元102还可以从网络侧接收要启用哪些UE发起的波束管理功能的指示以及/或者相关的参数。例如，执行单元102可以从网络侧接收如下中的一个或多个：启用UE发起的波束激活或波束选择的指示、针对哪些信道或信号启用UE发起的波束激活或波束选择、UE可以激活或选择多少个上行或下行波束，等等。应该注意，这仅是一个示例，网络侧可以根据需要对UE发起的波束管理功能进行具体配置。
综上所述，根据本实施例的电子设备100通过采用UE发起的波束管理过程，能够响应于物理层波束事件的发生进行波束管理，从而减少波束管理过程带来的时延，提高通信质量。
<第二实施例>
图11示出了根据本申请的一个实施例的用于无线通信的电子设备200的功能模块框图，如图11所示，电子设备200包括：收发单元201，被配置为接收UE发起的波束管理过程中的指示信息；以及执行单元202，被配置为响应于指示信息执行波束管理操作。
其中，收发单元201和执行单元202可以由一个或多个处理电路实现，该处理电路例如可以实现为芯片、处理器。并且，应该理解，图11中所示的电子设备中的各个功能单元仅是根据其所实现的具体功能而划分的逻辑模块，而不是用于限制具体的实现方式。
电子设备200例如可以设置在网络侧或者可通信地连接到网络侧。本申请中所述的网络侧可以是基站比如gNB、eNB、TRP、接入点(Access Point,AP)等。这里，还应指出，电子设备200可以以芯片级来实现，或者也可以以设备级来实现。例如，电子设备200可以工作为网络侧本身，并且还可以包括诸如存储器、收发器(未示出)等外部设备。存储 器可以用于存储网络侧实现各种功能需要执行的程序和相关数据信息。收发器可以包括一个或多个通信接口以支持与不同设备(例如，UE、其他基站等等)间的通信，这里不具体限制收发器的实现形式。
根据本实施例的电子设备通过接收来自UE的有关波束管理的指示信息，支持UE发起的波束管理。在下文中，与第一实施例中相同或相应的内容不再重复阐述，可以参照第一实施例中所述。
在一个示例中，指示信息包括波束扫描触发信息，收发单元201可以经由UCI或MAC CE从UE接收波束扫描触发信息。例如，UE在检测到物理层BM事件时，认为需要进行非周期的波束扫描，将向网络侧发送波束扫描触发信息。
波束扫描触发信息可以包括用于触发下行波束扫描的信息，在该信息经由UCI接收的情况下，包括指示激活状态的CSI-AperiodicTriggerState的信息，在该信息经由MAC CE接收的情况下，包括指示激活状态或非激活状态的CSI-AperiodicTriggerState的信息。CSI-AperiodicTriggerState指向一个非周期CSI-RS资源集合。
相应地，执行单元202在接收到指示激活状态的CSI-AperiodicTriggerState的下行波束扫描信息的情况下，根据该CSI-AperiodicTriggerState触发非周期的CSI-RS波束扫描，如图2所示，执行单元202可以通过DCI来进行动态触发。执行单元202在接收到指示非激活状态的CSI-AperiodicTriggerState的下行波束扫描信息的情况下，激活相应的CSI-AperiodicTriggerState并触发非周期的CSI-RS波束扫描。在这种情况下，执行单元202认为UE也已经激活该CSI-AperiodicTriggerState。类似地，执行单元202可以通过DCI来进行动态触发。
仍然参照图2，当CSI-AperiodicTriggerState所指向的CSI-RS资源集合的Repetition参数为打开(ON)的时候，在空间上重复传输CSI-RS以便使UE找到合适的接收波束，即，UE进行接收波束扫描。在这种情况下，UE可以不向网络侧报告自己找到的合适的波束。相反，在CSI-RS资源集合的参数Repetition为关闭(OFF)的时候，表示该资源集合中的CSI-RS资源使用不同的发射波束，其目的是为了找到合适的下行发射波束。在这种情况下，UE需要向网络侧上报所找到的合适的波束，收 发单元201执行相应的接收。
此外，波束扫描触发信息可以包括用于触发上行波束扫描的信息，该信息可以包括aperiodicSRS-ResourceTrigger，执行单元202响应于该信息向UE发送确认消息，以允许UE发送非周期SRS，如图3所示。在完成SRS波束扫描后，执行单元202对上行波束进行更新。
在另一个示例中，指示信息可以包括UE上报的参考信号测量结果。如第一实施例中所述，在UE执行基于DMRS的被动式的波束检测的情况下，该参考信号测量结果可以包括以下之一：与DMRS对应的TCI状态ID，与DMRS对应的TCI状态中包括的CSI-RS或SSB的ID。由于DMRS本身没有资源ID，因此UE在上报时可以借用TCI状态ID或者CSI-RS或SSB的ID。此外，指示信息中还可以包括对应的DMRS的RSRP。具体示例可以参见图7A和图7B，在此不再重复。
在另一个示例中，指示信息可以包括用于波束激活或波束选择的UE建议的波束的信息。如前所述，对于波束变化相对静态的控制信道或信号，NR***往往使用波束激活的概念；对于波束变化相对动态的数据信道，NR***往往使用波束选择的概念，即从多个激活的波束中选择一个最合适的波束来使用。
UE例如基于测量等向网络侧推荐哪些上行或下行波束应该被激活或选择，并将其信息包括在指示信息中提供给网络侧。例如，收发单元201可以通过UCI或MAC CE从UE接收建议的波束的信息。
此外，收发单元201还可以向UE发送指示UE从中进行建议的波束的范围的信息，即，网络侧提前设定一个范围，UE在该范围内建议可以激活或选择的波束。通过将UE自主选择或激活的波束限定在网络侧配置或者指定的范围内，可以缩小UE上报的波束的范围，从而减少UE上行的的信令开销。另外，收发单元201还可以通过MAC CE向UE发送对于该范围的调整的信息，以动态地调整UE自主波束激活和选择的范围。
例如，UE建议的波束的信息可以包括能够用于上行波束和下行波束两者的统一TCI状态。或者，上行波束的信息包括TCI状态，下行波束的信息包括SRI。
收发单元201在接收到来自UE的建议的波束的信息后，针对该接 收发送ACK或NACK消息。
在图8的示例中，在网络侧正确接收并认可UE建议的波束的情况下，收发单元201向UE发送ACK消息。即，ACK表示网络侧正确接收到PUSCH并且认可(或确认)PUSCH所承载的UCI或MAC CE的内容、即波束激活或选择的信息。在这种情况下，经过一段时间(可以以符号为单位或者以ms为单位来测量)后，UE所建议的波束生效。反之，NACK表示网络侧没有正确接收到PUSCH或者不认可UE建议的波束，在这种情况下，UE所建议的波束不能生效。
在图9的示例中，在网络侧正确接收并认可UE建议的波束的情况下，收发单元201向UE发送ACK消息并在预定时间窗口内发送另外的指示认可的DCI。即，ACK消息表示网络侧正确接收了PUSCH，另外发送的DCI表示网络侧认可UE建议的波束。如果网络侧不认可UE建议的波束，则不发送另外的DCI，UE在预定时间窗口内没有收到该另外发送的DCI，则获知其激活或选择的波束没有得到网络侧的认可，即，UE自主激活或选择的波束无效，仍然使用旧的波束。反之，网络侧认可UE建议的波束，则在预定时间窗口内发送另外的DCI，UE收到后则获知其激活或选择的波束得到了网络侧的认可，从而在预定时间窗口之后，所建议的波束波束生效。
在图10的示例中，在网络侧正确接收但是不认可UE建议的波束的情况下，收发单元201向UE发送ACK消息并在预定时间窗口内发送另外的包括网络侧改写的波束的信息的DCI。即，网络侧在正常的情况下不对建议的波束进行确认。如果网络侧认可UE建议的波束，则接下来在预定时间窗口内保持静默，经过一段时间后，UE建议的波束生效；而如果网络侧不认可UE建议的波束，则通过另外的DCI来改写UE建议的波束(图10中所示的情形)，经过一段时间后，网络侧改写的波束生效。
另外，当UE被配置了多个分量载波、即采用载波聚合时，有些分量载波(component carrier，CC)可以使用相同的波束对进行通信。即，当UE激活或选择一个波束时，比如某一个特定的TCI状态，该TCI状态所包含的CSI-RS或SSB除了在当前的服务小区的CC上适用外，在其他的小区的CC上也同样适用，因此可以进行跨CC的UE发起的波束激活或波束选择。
具体地，收发单元201还可以被配置向UE发送分量载波的列表，UE建议的波束适用于列表中的各个分量载波。即，网络侧为UE提前配置能够适用建议的波束的多个CC。
此外，收发单元201还可以被配置为向UE发送是否启用UE发起的波束管理的功能的指示，例如，收发单元201可以经由RRC信令来发送该指示。收发单元201还可以向UE发送要启用哪些UE发起的波束管理功能的指示以及/或者相关的参数。例如，收发单元201可以向UE发送如下中的一个或多个：启用UE发起的波束激活或波束选择的指示、针对哪些信道或信号启用UE发起的波束激活或波束选择、UE可以激活或选择多少个上行或下行波束，等等。应该注意，这仅是一个示例，网络侧可以根据需要对UE发起的波束管理功能进行具体配置。
综上所述，根据本实施例的电子设备200通过支持UE发起的波束管理过程，能够使得UE响应于物理层波束事件的发生进行波束管理，从而减少波束管理过程带来的时延，提高通信质量。
