具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
图1是根据本公开的实施例示出的一种波束配置请求方法的示意流程图。本实施例所示的波束配置请求方法可以适用于终端，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等电子设备。所述终端可以作为用户设备与基站通信，所述基站包括但不限于4G基站、5G基站、6G基站。在一个实施例中，所述基站可以是后续任一实施例所述的波束配置请求方法所适用的基站。
如图1所示，所述波束配置请求方法可以包括以下步骤：
在步骤S101中，响应于确定所述终端进入省电状态，向基站发送省电指示。
其中，所述省电指示用于请求所述基站减少为所述终端配置的候选波束的数量。
在一个实施例中，为了在波束失败后实现快速恢复，基站可以为终端配置候选波束集合，其中包括有若干候选波束。终端不仅可以对当前服务波束进行测量，还可 以对该候选波束集合中的候选波束进行测量。后续，若终端检测到当前服务波束故障，则可以根据测量结果在候选波束中选择波束来替代故障的波束，从而实现快速波束恢复。
在一个实施例中，终端为了减少功耗，可以在确定进入省电状态的情况下，向基站发送省电指示。基站在接收到该省电指示后，可以减少为该终端配置的候选波束的数量。
在一个实施例中，基站在接收到省电指示后，可以先确定当前为该终端配置的候选波束集合中候选波束的数量，然后为该终端配置更新后的候选波束集合，并且该更新后的候选波束集合中候选波束的数量少于更新前的数量。
例如更新前的候选波束集合A中候选波束的数量为n，更新后的候选波束集合B中候选波束的数量为m，m可以小于n，m和n为正整数。
其中，可选的，基站可以通过无线资源控制RRC信令中的candidateBeamRSList参数来配置候选波束集合。可选的，该候选波束集合中最多可包含64个候选波束。
根据图1所示的实施例，终端可以对基站重配置的候选波束进行测量，相较于发送省电指示之前配置的候选波束，重配置的候选波束数量减少，从而减少了终端所需要测量的候选波束的数量，减少了终端功耗。
在一个实施例中，基站在接收到省电指示后，可以确定终端的位置，然后针对更新前的候选波束集合，预测其中每个候选波束在该位置的信号强度，并根据预测的信号强度(例如由大到小)对更新前的候选波束集合中的波束进行排序，进而在确定更新后的候选波束集合时，可以根据排序确定。
例如更新后的候选波束集合B中的m个候选波束，可以是候选波束集合A中n个候选波束排序后的前m个波束。据此，有利于确保更新后的候选波束集合中的候选波束，相对于终端的信号强度加大，以便确保终端的通信质量。
在一个实施例中，终端可以根据多种方法来判断是否进行省电状态，下面结合图2和图3来介绍两个具体实施例。
图2是根据本公开的实施例示出的一种波束配置请求方法的示意流程图。如图2所示，所述方法还包括：
在步骤S201中，响应于接收到的下行波束的信号强度大于预设强度，确定所 述终端进入省电状态。
在一个实施例中，终端对当前服务的下行波束进行测量，若该下行波束的信号强度大于预设强度，则确定自身进入省电状态。
其中，可选的，预设强度可以是终端自身确定的，或者也可以是终端根据基站指示所确定的。
需要说明的是，终端在接收到的下行波束的信号强度较大时，可以确定当前服务波束的信号质量较好，出现故障的概率较低，因而终端需要使用候选波束的概率较低；同时，根据当前服务波束的信号质量较好，可以推测，候选波束中，每个候选波束的可用概率也越高，也就是说，终端能从较少的候选波束中确定出可以替代当前服务波束的候选波束。由此，终端为了节约功耗，可以向基站发送省电指示，以请求基站减少配置的候选波束的数量。
在一个实施例中，终端还可以根据上述下行波束的强度，来向基站请求对应的候选波束的数量。
在一个实施例中，终端可以确定与所述信号强度相关联的目标数量，可选的，终端可以向基站发送该目标数量，例如可以将目标数量携带在省电指示中。可选的，该省电指示可以用于请求所述基站将为所述终端配置的候选波束的数量减少至不超过所述目标数量。
在一个实施例中，终端可以预先设置信号强度与目标数量的关联关系，然后根据该关联关系确定当前下行波束对应的目标数量。终端可以将该目标数量发送给基站，基站在接收到终端发送的目标数量后，可以为终端重新配置候选波束，并确定该重配置的候选波束的数量。在一个实施例中，基站可以为终端配置不超过该目标数量的候选波束。
在一个实施例中，基站在接收到省电指示后，可以根据从当前已配置的候选波束中，选择出不大于目标数量的候选波束，然后将选择出的候选波束配置给终端。其中，可选的，基站在选择目标数量的候选波束时，可以根据候选波束的信号强度来确定，例如可以按照信号强度从大到小选择不大于目标数量的候选波束。
在一个实施例中，基站在根据信号强度确定目标数量时，可以确定目标数量与所述信号强度反相关，即信号强度越大，目标数量越少。
举例来说，终端可以预设多个信号强度区间，且每个信号强度区间对应一个目 标数量。如表1所示，表1示例性示出了信号强度与目标数量的对应关系。
信号强度 目标数量
不大于X /
大于X且不大于Y A
大于Y且不大于Z B
大于Z C
表1
如表1所示，定义了4个信号强度区间，其中，X可以为图2所示实施例中的预设强度。也就是说，当信号强度不大于该预设强度X时，终端不会进入省电状态，因而终端不会通过目标数量来限制基站所配置的候选波束的数量。
当终端接收到的下行波束的信号强度大于X且不大于Y时，终端可以确定目标数量为A。从而，基站为终端重新配置的候选波束的数量不超过A。举例来说，A可以为30，则基站为终端重新配置的候选波束的数量不超过30，例如可以按照信号强度从大到小，选择不大于30个(例如20个、30个等)的候选波束。
与上述方法类似，当终端接收到的下行波束的信号强度大于Y且不大于Z时，终端可以确定目标数量为B，从而请求基站为重新配置的候选波束的数量不超过B；当终端接收到的下行波束的信号强度大于Z时，终端可以确定目标数量为C，从而请求基站为重新配置的候选波束的数量不超过C。
其中，上述目标数量A>B>C。
需要说明的是，表1所示实施例只是示例性说明，终端还可以采用其他方法来确定信号强度与目标数量的关联关系，一般只要满足目标数量与所述信号强度反相关即可，这里不再赘述。
至此，完成了图2所示的实施例。根据图2所示的实施例，终端可以根据信号强度来确定是否进入省电状态。在信号强度较弱的情况下，当前服务波束故障率高，且候选波束的可用率低，因而可以配置相对较多的候选波束，以保障快速波束恢复可以被正常使用；在信号强度较强的情况下，当前服务波束故障率低，且候选波束的可用率高，因而可以配置数量相对较少的候选波束，以更好地节约功耗。
图3是根据本公开的实施例示出的一种波束配置请求方法的示意流程图。如图 3所示，所述方法还包括：
在步骤S301中，响应于所述终端的剩余电量小于预设电量，确定所述终端进入省电状态。
在一个实施例中，终端可以判断自身的电量，若电量小于预设电量，则确定自身进入省电状态。
在一个实施例中，所述电量可以是占总电量的比例。例如预设电量可以是40％，则终端判断自身电量小于40％时，确定进入省电状态。
在一个实施例中，终端可以确定剩余电量与目标数量的关联关系，根据自身电量确定目标数量后，向基站发送该目标数量后，请求基站将为所述终端配置的候选波束的数量减少至不超过所述目标数量。可选的，终端在确定目标数量时，可以确定目标数量与剩余电量成正相关，即终端剩余电量越少，所确定的目标数量越少，以更好的节约终端功耗。这里，确定关联关系的具体方法可以参考图2所示实施例中信号强度与目标数量的关联关系，这里不再赘述。
需要说明的是，减少候选波束的数量，可能会导致终端的通信质量下降。举例来说，可能导致终端在检测到当前服务波束故障时，无法及时切换到候选波束。在一个实施例中，当剩余电量小于预设电量时，终端可以请求用户指示是否向基站请求减少配置的候选波束，并提示用户若减少候选波束可能导致性能下降等问题。基于此，终端可以根据用户配置来确定是否向基站请求减少配置的候选波束。
至此，完成了图3所示的实施例。根据图3所示的实施例，终端可以根据自身电量来确定是否进入省电状态。在剩余电量较多的情况下，终端优先保障功能实现，则可以配置相对较多的候选波束，以保障快速波束恢复可以被正常使用；在剩余电量较小的情况下，终端优先节约功耗，则可以配置相对较少的候选波束。
需要说明的是，上述实施例只是示例性说明，终端还可以通过其他方法来确定是否进入省电状态，例如可以根据用户配置，当用户指示进入省电状态时，进入省电状态；或者终端也可以将图2实施例中的信号强度与图3实施例中的剩余电量结合起来，例如当信号强度大于预设强度且剩余电量小于预设电量时，确定终端进入省电状态等，这里不再赘述。
在一个实施例中，终端在进入省电状态后，还可以根据当前配置的候选波束的数量，来确定是否向基站发送省电指示。在一个实施例中，所述响应于确定所述终端 进入省电状态，向基站发送省电指示包括：响应于确定所述终端进入省电状态，且所述基站为所述终端配置的候选波束的数量大于预设阈值，向基站发送省电指示。
举例来说，终端可以预先设置一个数量阈值，当终端进入省电状态后，若判断当前已配置的候选侯波束数量大于该预设阈值，则向基站发送省电指示。
在一个实施例中，该预设阈值通常大于终端预设的与信号强度相关联的目标数量。例如目标数量如表1所示，则该预设阈值的数量可以大于A。基于此，终端在进入省电状态后，可以在已配置的候选波束的数量大于该预设阈值时，请求基站减少候选波束；在已配置的候选波束的数量不大于该预设阈值时，无需请求基站减少候选波束。
在一个实施例中，终端在进入省电状态后，还可以根据当前配置的候选波束的数量是否超过当前性能对应的目标数量，其中，当前性能对应的目标数量，可以为：信号强度和/或剩余电量对应的目标数量。若超过该目标数量，则终端请求基站减少候选波束，若未超过该目标数量，则终端无需请求基站减少候选波束。
在一个实施例中，终端在离开省电状态后，还可以向基站发送结束指示，下面结合图4来进行介绍。
图4是根据本公开的实施例示出的另一种波束配置请求方法的示意流程图。如图4所示，所述方法还包括：
在步骤S401中，响应于确定所述终端离开省电状态，向基站发送结束指示。
其中，所述结束指示用于请求所述基站将为所述终端配置的候选波束的数量，恢复至接收到所述省电指示之前为所述终端配置的候选波束的数量。
在一个实施例中，终端离开省电状态的方法可以与进入省电状态的方法相对应，例如，终端在接收到的下行波束的信号强度不大于预设强度，或者终端在剩余电量不小于预设电量时，可以确定离开省电状态。
在一个实施例中，终端在离开省电状态后，可以向基站发送结束指示。基站在接收到该结束指示后，可以重新为终端配置候选波束。在一个实施例中，该重配置的候选波束的数量，恢复至接收到省电指示之前所配置的候选波束的数量。在另一个实施例中，基站可以根据终端的情况重新确定候选波束，且不会对候选波束的数量进行限制。当然，若采用RRC信令中的candidateBeamRSList参数来配置候选波束，则最多配置64个候选波束。
至此，完成了图4所示的实施例。根据图4所示的实施例，终端可以在离开省电状态后，及时向基站撤销对候选波束的数量限制，以保障后续快速波束恢复的正常实现。
图5是根据本公开的实施例示出的一种波束配置方法的示意流程图。本实施例所示的波束配置方法可以适用于基站，所述基站包括但不限于4G基站、5G基站、6G基站。所述基站可以与作为用户设备的终端进行通信，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等电子设备。在一个实施例中，所述终端可以是上述任一实施例所述波束配置请求方法所适用的终端。
如图5所示，所述波束配置方法可以包括以下步骤：
在步骤S501中，响应于接收到终端发送的省电指示，减少为所述终端配置的候选波束的数量。
在一个实施例中，终端在进入省电状态后，可以向基站发送省电指示。基站在接收到该省电指示后，可以先确定当前为该终端配置的候选波束的数量，然后为该终端重新配置候选波束，并且该重新配置的候选波束少于之前配置的候选波束。
例如，基站可以通过无线资源控制RRC信令中的candidateBeamRSList参数来配置候选波束集合，且重新配置后的候选波束集合中的候选波束数量，少于更新前的数量。
根据图5所示的实施例，基站可以减少为终端配置的候选波束，使得终端减少需要测量的候选波束的数量，从而减少了终端功耗。
在一个实施例中，终端还可以通过省电指示来明确指示候选波束的数量。在一个实施例中，所述省电指示还包括目标数量；所述减少为所述终端配置的候选波束的数量，包括：将为所述终端配置的候选波束的数量减少至不超过所述目标数量。
基站在接收到该目标数量后，可以确定为该终端配置数量不超过该目标数量的候选波束。例如，基站可以根据从当前已配置的候选波束中，选择出不大于目标数量的候选波束，然后将选择出的候选波束配置给终端。
图6是根据本公开的实施例示出的另一种波束配置方法的示意流程图。如图6所示，所述方法还包括：
在步骤S601中，响应于接收到终端发送的结束指示，将为所述终端配置的候 选波束的数量，恢复至接收到所述省电指示之前为所述终端配置的候选波束的数量。
在一个实施例中，终端在离开省电状态后，可以向基站发送结束指示。基站在接收到该结束指示后，可以重新为终端配置候选波束，且该配置的候选波束的数量可以恢复到在接收到省电指示之前所配置的候选波束的数量。
根据图6所示的实施例，基站可以在终端离开省电状态后，及时将候选波束的数量恢复到非省电状态，以保障后续快速波束恢复的正常实现。

下面说明一个波束配置请求方法的具体实施例，可以应用于基站，该方法包括：

下面结合特定的技术细节，说明根据本发明的一种波束配置方法、以及波束配置请求方法。基站通过配置参考信号强度门限值判断终端是否进入省电状态，如果UE满足条件进入省电状态，则UE上报indication，基站收到后，减少配置的候选波束资源集数目，从而减少UE对候选波束的测量，进而省电。
具体包括以下步骤：
第1步：当前网络通过参数candidateBeamRSList为终端UE配置候选波束集，共m个波束；
第2步：网络通过配置不同的参考信号强度门限值(门限值x、y和z，且门限值x<y<z)来判断终端UE是否进入省电状态；
第3步：如果当前服务的下行波束的信号强度大于配置的门限值，则判定终端UE可以进入省电状态，此时网络将配置的候选波束集合中参考信号数目设置为对应个数(数值a、b和c，分别对应门限值x、y和z且数值m>a>b>c)，然后终端UE按照Rel-15/16TS38.133中定义的波束测量行为进行测量；
第4步：一旦终端UE不满足省电状态的条件时，则基站按照原本规则更新candidateBeamRSList，终端UE按照Rel-15/16TS38.133中定义的波束测量行为进行测量。
根据上述步骤，可以实现：当终端UE满足省电状态下的条件时，终端UE可以减少候选波束的测量以达到省电的效果。
