其中，终端11可以是指向用户提供语音和/或数据连通性的设备。终端11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，终端11可以是物联网终端，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网终端的计算机，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、远程终端(remote terminal)、接入终端(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户终端(user equipment， UE)。或者，终端11也可以是无人飞行器的设备。或者，终端11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通信设备。或者，终端11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。

其中，基站12可以是4G系统中采用的演进型基站(eNB)。或者，基站12也可以是5G系统中采用集中分布式架构的基站(gNB)。当基站12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、媒体访问控制(Media 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12的具体实现方式不加以限定。
基站12和终端11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，终端11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V2V(vehicle to vehicle，车对车)通信、V2I(vehicle to Infrastructure，车对路边设备)通信和V2P(vehicle to pedestrian，车对人)通信等场景。

本公开实施例涉及的执行主体包括但不限于：蜂窝移动通信系统中的手机终端，以及网络侧设备，如基站等接入网设备，以及核心网等。
相关技术中波束管理的基本组成可以包括如下几个方面：
一、波束扫描：不同方向的波束以时分复用的方式在特定区域实现覆盖，每个波束携带信道状态信息参考信号(CSI-RS，Channel State Information-Reference Signal)等参考信号，经过波束扫描，UE可获得不同方向的波束所携带的参考信号。
二、波束测量：UE测量接收波束所携带的参考信号，并通过计算参考信号的信号质量获取该方向的波束质量。
三、波束上报：UE报告波束所携带参考信号的测量信息，测量信息应至少包括测量质量和波束指示信息。
四、波束确定：基站和UE选择发送/接收波束。例如，在连接态下， 基站应根据UE的反馈信息确定发送波束，并向用户指示该波束。
上述波束管理过程中，基站配置波束测量周期后循环进入如下波束测量过程：首先，基站根据用户的接入波束，确定UE大致方向，并根据UE的方向确定待测波束对集合，以及UE所需上报的下行波束数量L。然后基站为待测波束对集合配置CSI-RS，并将CSI-RS的配置信息通知UE。基站发送CSI-RS，UE则根据配置信息进行CSI-RS测量，并将最好的L个下行波束测量结果反馈到基站。最后基站综合考虑负载、波束测量结果等因素确定下行波束并指示给UE。
一方面，基站依据UE接入波束确定UE位置，由于波束定位误差大，基站获取到的UE当前位置不精确，故而基站需要扩大测量范围保证所选波束的质量。这将导致UE测量大量竞争力不匹配的波束对，造成较大的UE开销。
另一方面，业务到达时，基站调用先前测量所定的最优波束传输业务，并不考虑测量到业务调度间隔内的UE的移动性，可能会造成业务传输的质量较低。
如何，减少待测波束的数量，减小UE测量负载，以及业务到达是基站能选择当前最有波束进行业务传输，提高业务传输质量，是亟待解决的问题。
如图2所示，本示例性实施例提供一种波束确定方法，可以被蜂窝移动通信系统的基站执行，包括：
步骤201：基于通感信号在目标UE反射的回波信号，确定目标UE的感知信息；
步骤202：基于所述目标UE的感知信息，确定所述目标UE的待测波束。
UE可以是蜂窝移动通信系统中的手机等终端。UE可以用于接收感知 信息的通信设备。UE也可以发射感知信息。目标UE是基站需要确定与其进行通信的波束的UE。网络可以包括但不限于接入网、和/或核心网等。待测波束是采用波束赋形后得到的具有指向性的波束。待测波束可以包括下行波束。由于下行波束和上行波束具有一一对应关系，因此待测波束也可以是下行波束和上行波束组成的波束对。
在一种可能的实现方式中，该目标UE反射的回波信号，是目标UE基于通感信号在目标UE反射的回波信号，也可以是目标UE基于基站发送的其他信号反射的回波信号，其原理相通不再赘述。通感信号(通信感知信号)可以是蜂窝移动通信系统中，同时用于数据通信和环境感知的信号。通感信号可以是由基站发射，回波信号可以是通感信号在UE反射回基站的信号。通感信号，包括毫米波信号、或太赫兹信号等。
通感信号在UE反射的回波信号，可以包括但不限于：通感信号在持有UE的用户反射的回波信号、通感信号在设置有UE的设备反射的回波信号等。通感信号也可以是其他通信设备发送的，如通感信号也可以是其他基站或UE发射的。基站可以基于其他通信设备发送的通感信号在UE上发射的回波信号，确定UE的感知信息。
如图3所示，基站等可以采用具有发射天线阵的发射面板发射通感信号，采用具有接收天线阵的接收面板接收回波信号。通感信号可以是连续的突发信号，以进行连续的感知。
在一个实施例中，所述通感信号包括：承载同步信号块SSB的信号。
通感信号的发射端，如基站的发射面板等，可以发射SSB突发集(SSB Burst Set)。由回波信号的接收端，如基站的接收面板进行连续接收。SSB突发集中的SSB信号(承载SSB的信号)之间可以间隔预定时长，以减少已发射SSB信号的回波信号对当前发射的SSB信号的影响。
例如，可以在前一个SSB信号的回波信号被接收后，再发射后一个SSB 信号，以减小前一个SSB信号的回波信号与后一个SSB信号的干扰(例如旁瓣干扰)等。
在一个实施例中，所述感知信息包括至少以下之一：
方位信息；
距离信息；
速度信息。
这里，方位信息可以是UE相对基站等参照物的相对方位信息，也可以是地理位置方位信息。方位信息可以包括，UE相对基站的方位角等。示例性的，可以根据从接收天线面板上相邻天线阵元接收的回波信号的相位差确定方位信息。
距离信息可以是UE相对基站等参照物的相对方位信息。示例性的，可以根据基站发射通感信号到接收回波信号的信号飞行时间等确定基站与UE之间的距离。
速度信息，可以基于多个时间点UE的距离和方位来确定。
在一个实施例中，可以但不限于采用感知模型、机器学习模型等，基于通感信号和接收到的通感回波信号确定感知信息。
在一个实施例中，如图4所示，其中所述通感信号可以为承载SSB的信号；基站确定感知信息的具体步骤包括：
步骤401：基站接收目标UE反射的SSB信号的回波信号。
步骤402：基站对反射后接收到的调制符号矩阵进行逐元素复除得到矢量矩阵。
一种实施例中，SSB以窄波束的形式通过基站发射面板发射，并在遇到用户时反射回来；基站通过接收面板捕获回波信号，并在回波信号中提取所述的感知信息。进一步的，基站基于回波信号确定调制符号矩阵。
如图5所示，步骤402具体包含如下两个步骤：
步骤4021：基站接收到SSB经过物体反射后得到的接收调制符号矩阵。
示例性的，接收调制符号矩阵(D Rx) μ,n可以采用表达式(1)表示：
Figure PCTCN2022083441-appb-000001
其中，A(μ,n)表示复振幅因子，(D Tx) μ,n表示发送的调制符号矩阵，
Figure PCTCN2022083441-appb-000002
表示反射符号的距离对接收调制符号的影响，
Figure PCTCN2022083441-appb-000003
表示多普勒对接收调制符号的影响，μ表示OFDM符号索引，n表示子载波索引。
由于目标UE可能是处于运动状态，因此其可以被视为运动物体，从而通过步骤4021确定该SSB经过在运动状态下的目标UE反射后得到的接收调制符号矩阵。
步骤4022：基站对接收调制符号矩阵进行逐元素复除得到矢量矩阵。
示例性的，矢量矩阵可以采用表达式(2)表示：
Figure PCTCN2022083441-appb-000004
反射符号的距离对接收调制符号的影响k R(n)可以采用表达式(3)表示：
Figure PCTCN2022083441-appb-000005
其中，Δf表示子载波间隔，R表示用户与基站间的距离，c 0表示光速，j表示复数。
多普勒对接收调制符号的影响k D(μ)可以采用表达式(4)表示：
Figure PCTCN2022083441-appb-000006
其中，T OFDM表示OFDM符号持续时间，v rel表示用户的速度，f c表示载波频率；其中j表示复数。
步骤403：基站对矢量矩阵的每一行进行离散傅立叶变换。
步骤404：基站对步骤403得到的矩阵的每一列进行逆离散傅立叶变换。
步骤405：基站基于步骤404得到的表示距离和多普勒的矩阵，分离出用户的距离息和速度信息。
步骤406：基站从接收天线面板上相邻天线阵元接收的信号的相位差中分离出用户的方位角信息。
示例性的，相邻天线阵元接收的信号之间的相位差为：
Figure PCTCN2022083441-appb-000007
其中，β＝2π/λ表示相位传播因子，λ表示波长，θ k表示第k个信号源的方向，d表示相邻天线阵元之间的距离。
如此，通过通感信号确定目标UE的位置信息，由于通感信号相较波束定位具有更高的定位精度，因此，基站可以选择更少的待测波束供UE进行波束测量，如此，从而降低UE的测量开销。
在一个实施例中，所述基于通感信号在目标UE反射的回波信号，确定目标UE的感知信息，包括：
所述基于通感信号在候选UE反射的回波信号，确定候选UE的感知信息，其中，所述候选UE包括所述目标UE；
基于候选UE的感知信息，和所述目标UE的预估位置信息，确定所述候选UE中所述目标UE的感知信息。
采用通信感知信号对UE进行感知，利用的是通感信号的回波特性。当存在多个UE(即候选UE)时，通过通感信号无法从多个UE中识别目标UE。
这里，可以将目标UE的预估位置信息与候选UE的感知信息进行对比，将差异值小于或等于对比阈值的候选UE确定为目标UE；或者，可以将多个候选UE的感知信息中与目标UE的预估位置信息差异值最小的一个候选UE确定为目标UE，并将该候选UE的感知信息确定为目标UE的感知信息。
例如，可以对比目标UE预测的距离信息和速度信息，与多个候选UE 的距离信息和速度信息进行比较，将距离信息和速度信息差异最小的一个候选UE确定为目标UE，并将该候选UE的感知信息确定为目标UE的感知信息。
目标UE的预估位置信息，可以是基站基于以下的任一种方式确定的：目标UE的接入波束和目标UE上报的无线信号测量结果确定的、目标UE上报的预估位置信息、以及在之前的感知过程中确定并预存在基站内的位置信息。
如此，基站可以确定目标UE对应的感知信息。在选择待测波束时，基站可以基于较为精确的目标UE的感知信息，缩小选择范围，减少缺乏竞争力的待测波束的数量，选择更少的待测波束供UE进行波束测量，如此，从而降低UE的测量开销。
在一个实施例中，所述目标UE的预估位置信息，是基于所述目标UE的接入波束和所述目标UE上报的第一信号测量结果确定的；
或者，
所述目标UE的预估位置信息，是预存在基站内的。
示例性的，如图6所示，基于候选UE的感知信息，和所述目标UE的预估位置信息，确定所述候选UE中所述目标UE的感知信息的具体步骤包括：
步骤601，基站通过通信感知技术确定信号覆盖范围内一个或多个UE的地理位置和移动速度。
可以理解的，基站并不确定UE与地理位置以及移动速度之间的对应关系。
步骤602，基站通过UE的接入波束和上报的无线信号第一测量结果预估UE的位置。
其中，无线信号第一测量结果可以示例性的为信道状态信息参考信号 接收功率(CSI-RSRP，Channel State Information Reference Signal Received Power)。
具体的，如图7所示，以CSI-RSRP为例，基站通过接入波束和CSI-RSRP预估UE位置的具体步骤包括：
步骤6021，基站根据UE的接入波束预估UE所处方位；
示例性的，该UE所处方位可以为角度(方位角)。
步骤6022，基站根据UE所处方位、CSI-RSRP、CSI-RSRP变化幅度和/或存储的UE空间区域信息，预估UE的位置参数；
其中，预估UE的位置参数，可以为UE的预估位置和移动速度，还可以包括其他参数。
步骤603，基站将UE的预估位置和移动速度与已确定的用户具体位置和移动速度进行对应。
步骤604，建立UE与感知信息的对应关系。
进一步的，基站可以维持并调整该UE与感知信息的对应关系；例如，在后续的感知过程中，或在后续的波束配置过程，调整该UE与感知信息的对应关系。
在本公开实施例中，已确定的用户具体位置和移动速度，是指基站通过通信感知技术确定的UE的位置和移动速度；既可以是前一次确定的用户具体位置和移动速度或前几次确定的用户具体位置和移动速度，也可以是历史上所有确定的用户具体位置和移动速度。
目标UE的预估位置信息，可以是基站基于目标UE的接入波束和上报的无线信号测量结果确定的，也可以是目标UE上报的，还可以是在之前的感知过程中确定的。
图8所示，本示例性实施例提供一种波束确定方法，可以被蜂窝移动通信系统的基站执行，包括：
步骤801：向所述目标UE发送所述待测波束的测量配置信息，其中，所述测量配置信息用于指示至少以下之一：
所述待测波束；
对所述待测波束的测量信号进行测量的测量周期；
所述待测波束的测量信号的配置参数；
UE上报第二测量结果的所述待测波束的数量，其中，所述第二测量结果是所述目标UE针对所述待测波束的测量信号进行测量得到的。
步骤801可以单独实施，也可以与本公开的任意一个实施例结合实施，例如与步骤201和步骤202一起被实施，在此不再赘述。
基站确定待测波束后，可以通过测量配置信息向UE指示测量配置。
测量配置信息通过待测波束的唯一指示标识指示待测波束。例如，测量配置信息可以包括：待测波束的波束(标识)ID。基站指示的待测波束可以是下行波束，也可以是波束对。
测量信号可以包括但不限于信道状态信息参考信号(CSI-RSRP，Channel State Information Reference Signal)、跟踪参考信号(TRS，Tracking Reference Signal)等。
测量信号的配置参数可以包括测量信号的传输资源等，如频域资源、时域资源、时频域资源。UE可以基于配置参数接收测量信号进行测量。UE可以基于可以向上报M个待测波束的第二测量结果，其中，M为大于或等于1的正整数。测量配置信息可以指示上报第二测量结果的所述待测波束的数量M。
在一个实施例中，所述向所述目标UE发送所述待测波束的测量配置信息，包括：
响应于所述测量配置信息的数据量大于数据量阈值，发送携带所述测量配置信息的无线资源控制RRC消息；
或
响应于所述测量配置信息的数据量小于数据量阈值，发送携带所述测量配置信息的下行控制信息DCI和/或媒体访问控制单元MAC CE。
其中，若所述测量配置信息的数据量等于数据量阈值，可以采用上述的两种方式中的任一种，在此并不限定。
由于基站可以基于目标UE对应的感知信息确定待测波束，因此相对相关技术中基站基于接入波束确定待测波束，基站可以缩小待测波束的范围，进而减少测量配置信息的数据量。
基站可以基于测量配置信息的数据量确定携带测量配置信息的信令。
其中，数据量阈值可以基于DCI和/或MAC CE的数据承载能力确定，当测量配置信息的数据量小于或等于数据量阈值时，将测量配置信息携带在DCI和/或MAC CE中发送给UE，相对RRC消息，通过DCI和/或MAC CE携带测量配置信息可以减少UE信令开销。
当测量配置信息的数据量大于数据量阈值时，可以采用RRC消息携带测量配置信息，以满足测量配置信息的传输需求。
在一个实施例中，所述基于通感信号在目标UE反射的回波信号，确定目标UE的感知信息，包括：
按感知周期，基于所述通感信号在所述目标UE反射的所述回波信号，确定所述目标UE的感知信息，其中，一个所述感知周期包括N个所述测量周期，其中，N为大于或等于1的正整数。
如图9所示，基站以感知周期为时间间隔，循环执行感知任务。在一个感知周期中，基站根据的感知信息指导多次波束测量，且波束测量以测量周期为时间间隔在1个感知周期内循环执行。
一个感知周期中，基站通过发送通感信号，如SSB突发集，来执行感知任务获取用户的感知信息，如：方位角、距离和速度等信息。基站根据 感知信息完成测量配置后，向测量配置信息发送给UE，以测量周期为时间间隔发送周期性测量信号，CSI-RS以支持周期性的波束测量，并在测量结束后发送DCI指示用户下行波束。
在一个实施例中，所述方法还包括：
在所述感知周期内，基于所述感知信息确定所述目标UE的位置变化；
基于所述目标UE的位置变化，确定更新所述测量配置信息的配置更新信息；
向所述目标UE发送所述配置更新信息。
其中，可以通过DCI或MAC CE发送所述配置更新信息。
如图9和图10所示，感知周期内，基站确定目标UE的感知信息后，基站会向目标UE发送测量配置信息，包括周期性CSI-RS，上传波束个数L以及测量周期等信息。基站可以基于测量配置信息的数据量确定携带测量配置信息的信令。测量配置信息可以由RRC消息携带。
如图10所示，在后续测量周期中，基站可以基于目标UE的感知信息预测目标UE的位置变化。例如，基站基于当前时刻距离获取感知信息的时刻的时间间隔，以感知信息中UE的距离、方位以及速度等，预测当前时刻UE的位置变化情况，进而基于当前时刻目标UE的位置确定需要目标UE进行测量的待测波束，并采用配置更新信息更新测量配置信息。配置更新信息可以是测量配置信息，也可以是其他专用信息。基站可以采用DCI和/或MAC CE携带配置更新信息，以减小信令开销。
在一个实施例中，当配置更新信息的数据量大于阈值时，可以采用RRC消息携带。
图11所示，本示例性实施例提供一种波束确定方法，可以被蜂窝移动通信系统的基站执行，包括：
步骤1101：接收所述目标UE基于所述测量配置信息对所述待测波束 的测量信号进行测量的第二测量结果；
步骤1102：基于所述第二测量结果从所述待测波束中确定所述目标UE的第一下行波束；
步骤1103：向所述目标UE发送指示所述第一下行波束的指示信息。
步骤1101～1103可以单独实施，也可以与本公开的其他实施例一起结合实施。例如，步骤1101～1103可以结合步骤201和步骤202一起被实施；或步骤1101～1103可以结合步骤801一起被实施。
UE基于测量配置信息，对待测波束的测量信号进行测量，得到各待测波束的第二测量结果。UE可以基于测量配置信息的要求，选择一定数量待测波束的第二测量结果发送给基站，例如，UE挑选质量最好的一定数量个下行波束组成下行候选波束集并上报基站，上报内容包括下行波束的第二测量结果，如：CSI-RS资源指示(CRI，CSI-RS Resource Indicator)和层-1参考信号接收功率(L1-RSRP，Layer-1 Reference Signal Received Power)等。
基站根据UE上报的第二测量结果确定第一下行波束，并指示用户。基站可以通过DCI携带第一下行波束的指示信息。
图12所示，本示例性实施例提供一种波束确定方法，可以被蜂窝移动通信系统的基站执行，包括以下至少之一：
步骤1201a：基于所述目标UE的感知信息，和当前时刻与向所述目标UE指示所述第一下行波束的时刻之间的间隔时间信息，确定的所述目标UE的第二下行波束；
步骤1201b：基于所述目标UE的感知信息，确定当前时刻所述目标UE所处的位置；基于当前时刻所述目标UE所处的位置的历史波束，确定的所述目标UE的第二下行波束。
确定第一下行波束之后，由于UE发生了移动或是其他变化，此时第一 下行波束不一定适用。因此本公开实施例中，需要确定当前时刻适用的第二下行波束。其中，可以周期性的重新确定第二下行波束，也可以基于其他触发条件发起确定第二下行波束。基站基于当前时刻距离基站指示第一下行波束的时刻之间的间隔时间，以感知信息中UE的参数，预测当前时刻UE所处的波束，将该波束确定为第二波束，并向UE进行指示，用于传输当前时刻的业务。其中，感知信息中UE的参数可以为：距离、方位以及速度等。
基站可以预先存储不同位置对应的波束。基站基于当前时刻距离基站指示第一下行波束的时刻之间的间隔时间，以感知信息中UE的参数，预测当前时刻UE所处的位置，并基于基站预先存储的该位置对应的第二波束向UE指示。
基站可以采用DCI指示第二下行波束。
如此，基站可以选择最优波束用于业务传输，从而提升波束管理性能。
以下结合上述任意实施例提供一个具体示例：
如图13所述，本实施例提供一种波束确定方法，该方法包括如下步骤：
步骤1301，基站配置感知周期和SSB突发集。
在一种可能的实现方式中，步骤1301包含如下两个步骤：

步骤1303，基站根据感知信息为用户确定待测可选波束对集合、下行候选波束个数以及测量周期，并配置周期性CSI-RS。
在一种可能的实现方式中，步骤1303包含如下三个步骤：
步骤13031，基站根据步骤202获取的用户所在位置的角度、速度等信息选择用户可以测量且具有相似竞争力的波束对集合，并为用户配置需要上报的下行波束个数和测量周期。
步骤13032，基站根据301中配置的待测可选波束对集合配置用于波束测量的周期性CSI-RS。
步骤13033，基站通过RRC/DCI/MAC CE向用户更新波束测量的配置消息，包括下行候选波束个数L，周期性CSI-RS配置信息和测量周期等。

步骤13043，用户根据13042的计算结果挑选质量最好的L个下行波束组成下行候选波束集并上报基站，上报内容包括下行波束的CRI和L1-RSRP。
步骤1305，基站根据用户上报的反馈测量结果确定下行波束，并指示 用户。
在一种可能的实现方式中，步骤1305包含如下两个步骤：
步骤13051，基站根据用户的反馈结果结合感知信息确定下行波束。
步骤13052，基站通过DCI将下行波束指示用户。
如图14所述，本实施例提供一种波束确定方法，该方法包括如下步骤：
步骤1401，基站根据用户感知数据和历史数据等信息从下行候选波束集中匹配最优波束。
在一种可能的实现方式中，步骤1401包含如下三个步骤：
步骤14011，网络侧通知基站，用户的业务数据即将到达。
