请参考图1，其示出了本公开实施例提供的一种无线通信系统的结构示意图。如图1所示，无线通信系统是基于蜂窝移动通信技术的通信系统，该无线通信系统可以包括：若干个用户设备110以及若干个基站120。
其中，用户设备110可以是指向用户提供语音和/或数据连通性的设备。用户设备110可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，用户设备110可以是物联网用户设备，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网用户设备的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，站(Station，STA)、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程用户设备(remote terminal)、接入用户设备(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户设备(user equipment)。或者，用户设备110也可以是无人飞行器的设备。或者，用户设备110也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线用户设备。或者，用户设备110也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
基站120可以是无线通信系统中的网络侧设备。其中，该无线通信系统可以是第四代移动通信技术(the 4th generation mobile communication，4G)系统，又称长期演进(Long Term Evolution， LTE)系统；或者，该无线通信系统也可以是5G系统，又称新空口系统或5G NR系统。或者，该无线通信系统也可以是5G系统的再下一代系统。其中，5G系统中的接入网可以称为新一代无线接入网(New Generation-Radio Access Network，NG-RAN)。
其中，基站120可以是4G系统中采用的演进型基站(eNB)。或者，基站120也可以是5G系统中采用集中分布式架构的基站(gNB)。当基站120采用集中分布式架构时，通常包括集中单元(central unit，CU)和至少两个分布单元(distributed unit，DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体接入控制(Medium Access Control，MAC)层的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本公开实施例对基站120的具体实现方式不加以限定。
基站120和用户设备110之间可以通过无线空口建立无线连接。在不同的实施方式中，该无线空口是基于第四代移动通信网络技术(4G)标准的无线空口；或者，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口；或者，该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
在一些实施例中，用户设备110之间还可以建立E2E(End to End，端到端)连接。比如车联网通信(vehicle to everything，V2X)中的车对车(vehicle to vehicle，V2V)通信、车对路边设备(vehicle to Infrastructure，V2I)通信和车对人(vehicle to pedestrian，V2P)通信等场景。
这里，上述用户设备可认为是下面实施例的终端设备。
在一些实施例中，上述无线通信系统还可以包含网络管理设备130。
若干个基站120分别与网络管理设备130相连。其中，网络管理设备130可以是无线通信系统中的核心网设备，比如，该网络管理设备130可以是演进的数据分组核心网(Evolved Packet Core，EPC)中的移动性管理实体(Mobility Management Entity，MME)。或者，该网络管理设备也可以是其它的核心网设备，比如服务网关(Serving GateWay，SGW)、公用数据网网关(Public Data Network GateWay，PGW)、策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)或者归属签约用户服务器(Home Subscriber Server，HSS)等。对于网络管理设备130的实现形态，本公开实施例不做限定。
为了便于本领域内技术人员理解，本公开实施例列举了多个实施方式以对本公开实施例的技术方案进行清晰地说明。当然，本领域内技术人员可以理解，本公开实施例提供的多个实施例，可以被单独执行，也可以与本公开实施例中其他实施例的方法结合后一起被执行，还可以单独或结合后与其他相关技术中的一些方法一起被执行；本公开实施例并不对此作出限定。
对辅小区的激活可以分为对已知辅小区的激活和对未知辅小区的激活。
当终端在辅小区激活前在协议约定的一段时间内向网络上报过辅小区的测量信息，且在协议约定的小区识别时间内该辅小区是可检测到的，则认为该辅小区是已知的。另外对于FR2的辅小区，额外要求在辅小区激活过程中的传输配置指示符(Transmission Configuration Indication，TCI)激活是基于终端上报的SSB或CSI-RS index确定。
否则认为辅小区是未知的。
如图2为针对未知辅小区的激活时序图。如图3为针对已知辅小区的激活时序图。如图2和图3所示，所示，无论针对未知辅小区还是已知辅小区，均需要进行激活命令处理以及时频同步等步骤。而针对未知辅小区还需要进行自动增益控制(AGC)，小区搜索，L1-RSRP测量等额外的步骤。
可以基于SSB执行辅小区激活，但是SSB测量受限于测量定时配置(Measurement Timing Configuration，SMTC)，一般周期时间比较长(一般的网络部署中，SMTC周期为20ms，40ms,或80ms)，特别是对于FR2未知辅小区激活来说，如图4所示，UE还需要进行接收波束扫描(RX beam sweeping)(例如，扫描8个方向的波束)执行L1-RSRP来确定最佳波束，造成辅小区激活时延较大。
因此，在辅小区激活过程中，提高辅小区激活效率，缩减辅小区激活过程的时延，是亟待解决的问题。
如图5所示，本公开实施例提供一种波束扫描方法，包括：
步骤501：至少根据服务小区的信号测量结果，确定辅小区激活过程中进行接收波束扫描的波束数量。
本公开实施例可以应用于但不限于移动通信系统中的手机终端等UE。
本公开实施例可以应用于但不限于基于SSB等参考信号执行辅小区激活的场景。
服务小区可以包括以下至少一项：主小区，激活的辅小区，待激活的辅小区。
在一个可能的实现方式中，辅小区激活包括：未知小区激活或已知小区激活。
在一个可能的实现方式中，测量波束可以是属于服务小区的波束。UE可以基于服务小区的参考信号资源进行无线信号测量，并确定信号测量结果。
在一个可能的实现方式中，信号测量结果可以是对SSB等参考信号进行无线信号测量得到的结果。
在一个可能的实现方式中，信号测量结果可以包括：信号强度、信号信噪比等。
UE的所处的位置和/或UE的运动状态(如，移动速度等)均能影响信号测量结果。因此，信号测量结果可以反应UE所处的位置和/或UE的运动状态。而UE所处的位置和/或UE的运动状态可以影响UE在辅小区激活过程需要进行接收波束扫描的波束数量。
在一个可能的实现方式中，UE可以基于信号强度等测量结果确定UE距离基站的位置。
在一个可能的实现方式中，UE可以基于信号强度等测量结果的变化情况确定UE距离基站的运动状态(如，移动速度等)。
示例性的，如果信号测量结果反应UE移动速度低于速度阈值，那么可以确定UE在使用辅小区过程中，跨越的波束数量较少，那么可以选择扫描较少数量的波束。相反，如果信号测量结果反应UE移动速度高于速度阈值，那么可以确定UE在使用辅小区过程中，跨越的波束数量较多，那么可以选择扫描较多数量的波束。
在一个可能的实现方式中，响应于UE接收到激活辅小区命令，至少根据服务小区的信号测量结果，确定辅小区激活过程中进行接收波束扫描的波束数量。
如此，UE可以基于信号测量结果，调整辅小区激活过程中进行接收波束扫描的波束数量。不再必须对全部波束进行接收波束扫描来确定最佳波束，从而减少了辅小区激活时延，提高了激活效率以及提高接收波束扫描的灵活性。
在一个实施例中，所述信号测量结果，包括：L3测量结果。
在一个可能的实施方式中，L3测量结果可以是由L1测量结果经过L1滤波得到的。
采用L3测量可以用于对无线资源管理的决策。
在一个实施例中，所述L3测量结果，包括：L3-参考信号接收功率。
L3-参考信号接收功率可以直接反应接收信号的强度，利于对UE位置和/或UE运动状态的评估。
在一个实施例中，所述接收波束扫描关联于所述辅小区激活过程中进行的以下至少一项：
自动增益控制AGC；
小区搜索；
L1参考信号接收功率测量；
时频同步。
UE在辅小区激活过程中，以下至少一项自动增益控制AGC；小区搜索；L1参考信号接收功率测量需要进行接收波束扫描，即测量多个接收波束。
UE可以在根据信号测量结果，确定的波束数量的波束中进行自动增益控制AGC、小区搜索、L1参考信号接收功率测量和/或时频同步。相对于采用固定数量的波束数量，接收波束扫描更灵活。
在一个可能的实现方式，UE可以在进行AGC、小区搜索、L1参考信号接收功率测量和时频同步任一项之前均单独确定波束数量，进而在确定的波束数量的波束内进行AGC、小区搜索、L1参考信号接收功率测量或时频同步。
如图6所示，本公开实施例提供一种波束扫描方法，包括：
步骤601：根据所述信号测量结果所在的测量结果阈值范围，确定进行所述接收波束扫描的所述波束数量；其中，不同所述信号测量结果阈值范围对应的所述波束数量相同或不同。
信号测量结果如果表征信号质量较好，那么待激活辅小区的波束的传输质量均能符合传输需求的几率较大，UE可以减少尝试的扫描波束数量。因此，信号测量结果如果表征信号质量较好，确定的扫描波束数量较少。
信号测量结果如果表征信号质量较差，那么待激活辅小区的波束的传输质量均能符合传输需求的几率较小，UE可以增加扫描尝试的波束数量。因此，信号测量结果如果表征信号质量较差，确定的扫描波束数量较多。
在一个可能的实现方式中，测量结果阈值范围可以由通信协议规定。
在一个可能的实现方式中，测量结果阈值范围可以由网络侧设备指示的。
在一个可能的实现方式中，不同测量结果阈值范围对应的波束数量可以由通信协议约定和/或网络侧设备指示。
在一个可能的实现方式中，测量结果阈值范围可以是采用信号测量结果阈值指示的。
测量结果阈值范围可以由通信协议约定/网络侧设备配置，测量结果阈值范围可以由多个不同的信号测量结果阈值如S1，S2，S3(S1＞S2＞S3)划分，不同的测量结果阈值范围对应于不同的扫描波束数量。例如：测量结果阈值范围＞S1对应于波束数量N1，测量结果阈值范围为S1～S2对应于波束数量N2，测量结果阈值范围S2～S3对应于波束数量N3，其中，N3＞N2＞N1。
在一个可能是实现方式中，响应于所述信号测量结果大于预定信号测量结果阈值，基于1个波束进行辅小区激活。即信号测量结果较优的情况下，可以只基于一个波束进行辅小区激活。
根据信号测量结果所在的测量结果阈值范围，确定的进行接收波束扫描的波束数量必然小于或等于相关技术中进行波束扫描的波束总数，因此，通过采用本实施例方法，可以减少进行接收波束扫描的波束数量，减少辅小区激活的时延。同时，通过设置多个不同的阈值，避免相关技术中对固定数量的波束进行扫描，可以达到灵活控制扫描波束数量的效果，使得能够通过调整阈值来根据实际需求来提高接收波束扫描的灵活性。
如图7所示，本公开实施例提供一种波束扫描方法，包括：
步骤701：根据两次测量分别得到的所述信号测量结果之间的差异值，确定进行所述接收波束扫描的所述波束数量。
这里，两次测量分别得到的所述信号测量结果可以是在进行的N次测量的信号测量结果中根据预定确定的，其中，N为大于或等于2的正整数。例如，可以选择最优信号测量结果和最差信号测量结果。
两次信号测量结果之间的差异值如果较小，说明UE移动速度较少，UE切换波束的时间间隔较长，较少的待激活辅小区波束可以满足传输需求，UE可以减少尝试的扫描波束数量。
两次信号测量结果之间的差异值如果较大，说明UE移动速度较块，UE切换波束的时间间隔较短，需要较多的待激活辅小区波束才能满足传输需求，UE可以增加尝试的波束数量。
通过信号测量结果之间的差异值可以确定UE的运动状态(如位置变化，移动速度等)，UE在辅小区激活过程中可以选择与运动状态匹配的波束数量进行接收波束扫描。不再必须对全部波束进行接收波束扫描来确定最佳波束，从而减少了辅小区激活时延，提高了激活效率以及提高接收波束扫描的灵活性。
如图8所示，本公开实施例提供一种波束扫描方法，包括：
步骤801：根据两次测量分别得到的所述信号测量结果之间的差异值，确定进行所述接收波束扫描的所述波束数量；
步骤802：根据所述差异值所在的差异值范围，确定进行所述接收波束扫描的所述波束数量；其中，不同所述差异值范围对应的所述波束数量相同或不同。
这里，步骤801的具体实施方式与步骤701相似，该步骤具体方案参见图7的步骤701，在此不再赘述。
在一个可能的实现方式中，差异值范围可以由通信协议规定。
在一个可能的实现方式中，差异值范围可以由网络侧设备指示的。
在一个可能的实现方式中，不同差异值范围对应的波束数量可以由通信协议约定和/或网络侧设备指示。
在一个可能的实现方式中，差异值范围可以是采用差异值阈值指示的。
差异值范围可以由通信协议约定/网络侧设备配置，差异值范围可以由多个不同的差异值阈值如S1，S2，S3(S1＞S2＞S3)划分，不同的差异值范围对应于不同的波束数量。例如：差异值范围<S3对应于波束数量N1，差异值范围S2～S3对应于波束数量N2，差异值范围S1～S2对应于波束数量N3，其中，N3＞N2＞N1。
在一个可能是实现方式中，响应于所述差异值小于预定最小差异值阈值，基于1个波束进行所述辅小区激活。即UE移动性较低的情况下，可以只基于一个波束进行辅小区激活。
根据所述差异值所在的差异值范围，确定的进行接收波束扫描的波束数量必然小于或等于相关技术中进行波束扫描的波束总数，因此，通过采用本实施例方法，可以减少进行接收波束扫描的波束数量，减少辅小区激活的时延。同时，通过设置多个不同的差异值范围，避免相关技术中对固定数量的波束进行扫描，可以达到灵活控制扫描波束数量的效果，使得能够通过调整阈值来根据实际需求来提高接收波束扫描的灵活性。
在一个实施例中，所述至少根据服务小区的信号测量结果，确定辅小区激活过程中进行接收波束扫描的波束数量，包括：
至少根据在所述服务小区中待激活辅小区测量得到的所述信号测量结果，确定所述待激活辅小区在所述辅小区激活过程中进行所述接收波束扫描的所述波束数量。
针对特定的辅小区，可以根据该辅小区的信号测量结果，确定该辅小区在激活过程中进行接收波束扫描的波束数量。
在一个可能的实现方式中，UE接收网络对未激活辅小区A的激活命令，UE根据辅小区A的信号测量结果所在的测量结果阈值范围，确定对辅小区A激活过程中进行接收波束扫描的波束数量。
在一个可能的实现方式中，UE接收网络对未激活辅小区A的激活命令，UE根据两次测量分别得到的辅小区A的信号测量结果之间的差异值，确定对辅小区A激活过程中进行接收波束扫描的波束数量。
在一个实施例中，所述至少根据服务小区的信号测量结果，确定辅小区激活过程中进行接收波束扫描的波束数量，包括：
根据设定时长内在所述服务小区测量得到的所述信号测量结果，确定辅小区激活过程中进行接收波束扫描的波束数量。
在一个可能的实现方式中，设定时长可以由通信协议规定。
在一个可能的实现方式中，设定时长可以由网络侧设备指示的。
在一个可能的实现方式中，信号测量结果之间的差异值，可以是设定时长内测得的多个信号测量结果之间的差异值。
在一个可能的实现方式中，UE根据设定时长内两次测量分别得到的信号测量结果之间的差异值 所在的差异值范围，确定进行所述接收波束扫描的所述波束数量。
UE可以按照预定的时长间隔在设定时长内和/或设定时长外进行无线信号测量。设定时长内可以进行多次测量，如进行N次测量，N为大于或等于2的正整数。可以取其中两次测量分别得到的信号测量结果之间的差异值。可以取设定时长内预定的两个信号测量结果之间的差异值。例如，可以是当前测得的信号测量结果，与设定时长内历史最优信号测量结果之间的差异值；或者可以是当前测得的信号测量结果，与设定时长内历史最差信号测量结果之间的差异值。
示例性的，在设定时长内，持续比较测得的信号测量结果，比较在该设定时长内的最大测量结果与最小测量结果之间的差异值，判断所在阈值范围。
在一个可能的实现方式中，UE根据设定时长内信号测量结果所在的测量结果阈值范围，确定进行所述接收波束扫描的所述波束数量。
在一个可能的实现方式中，响应于设定时长内测量得到三个以上的测量结果，可以基于当前测量结果与最优信号测量结果的差异值，确定辅小区激活过程中进行接收波束扫描的波束数量。这里，测量结果可以是在不同时刻内对同一信号进行测量得到的。例如，测量结果可以是在不同时刻内对同一测量波束的SSB信号进行测量得到的。
在设定时长内确定一个差异值，可以减少测量的乒乓效应，即减少信号测量结果的来回变换对差异值的影响。
在一个实施例中，所述测量结果是针对一个或多个测量波束进行测量得到的。
基站可以采用波束赋形技术等生成不同的波束，UE可以针对不同的波束进行测量。
在一个可能的实现方式中，响应于UE对多个测量波束进行测量，UE可以根据对多个测量波束分别测量得到的测量结果的统计值，确定辅小区激活过程中进行接收波束扫描的波束数量。
这里，测量结果的统计值可以包括但不限于以下一项：最高值；平均值；加权统计值。
在一个实施例中，所述测量波束是基于以下之一确定的：
通信协议；
网络侧的指示信息。
为了进一步解释本公开任意实施例，以下提供两个具体实施例。
示例一、
在一个可能的实现方式中，UE根据设定时长内两次测量分别得到的信号测量结果之间的差异值所在的差异值范围，确定进行接收波束扫描的所述波束数量。
这里，接收波束扫描可以针对于自动增益控制AGC；小区搜索；L1参考信号接收功率测量等激活步骤分别进行。
例如，相关技术中UE需要对8个波束进行接收波束扫描。采用本公开实施例的方法，UE可以在小区搜索之前确定设定时长内两次测量分别得到的信号测量结果之间的差异值，如果该差异值所在的差异值范围对应的波束数量为6，那么UE可以在6个波束内进行小区搜索，从而减少进行小区搜素的负载和时延。相似的，UE可以在L1参考信号接收功率测量之前确定设定时长内两次测量分 别得到的信号测量结果之间的差异值，如果该差异值所在的差异值范围对应的波束数量为8，那么UE可以在8个波束内进行L1参考信号接收功率测量。
以此类推，采用本公开实施例的方法，确定进行接收波束扫描的所述波束数量必然小于或等于相关技术中UE需要进行接收波束扫描的所述波束数量，从而可以减少进行行接收波束扫描的时延。同时，通过设置多个不同的差异值范围，避免相关技术中对固定数量的波束进行扫描，可以达到灵活控制扫描波束数量的效果，使得能够通过调整阈值来根据实际需求来提高接收波束扫描的灵活性。
示例二、
一种减少终端辅小区激活时延的方式
引入一种判断准则：在一段时间T内，判断特定波束beam的L3测量结果的变化值是否小于特定阈值S。
(S -Refence–S -measure)<S
其中：
S -Refence为参考值，S -measure为测量值；
“一段时间”的限制是可选的，若包括“一段时间”，该值可以由协议约定，也可以是网络可配的；
“特定beam”可以是协议约定/网络可配的一个或多个beam，该特定beam是UE当前服务小区的beam；
“L3测量结果”可以为L3-RSRP结果；
“特定阈值”可以由协议约定/网络可配的，可以是多个不同的门限值S1，S2，S3(S1＞S2＞S3)
UE评估该准则，若满足准则，则UE在后续辅小区激活过程中可以减少RX beam sweeping的个数，对应不同的门限值，波束扫描的个数可以减少为N1，N2，N3(N1＞N2＞N3)
UE可以在接收到激活辅小区命令之后执行准则的判断。
