具体实施方式
图1为本申请实施例提供的应用场景的结构示意图，如图1所示，可以包括：网络设备和终端。采用天线阵列对信号波束赋型，能够实现精准窄波束对用户数据提供服务，从而可以获得更远的覆盖距离，并减少信号干扰。因此，在5G高频通信中，在网络设备和终端侧都采用波束成形的方式进行信号发送和接收。当通过波束成形的方式进行信号发送和接收时，就涉及到了波束管理。本申请实施例中，在网络设备侧波束方向固定时，对终端侧的波束进行优化配置，以满足不同的业务场景需求，提高通信链路的稳定性。
以下，对本申请中的部分用语进行解释说明，以便于本领域技术人员理解：
网络设备：又称为无线接入网(Radio Access Network，RAN)设备，是一种将终端接入到无线网络的设备，可以是长期演进(Long Term Evolution，LTE)中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者中继站或接入点，或者5G网络中的基站，如发送和接收点(Transmission and Reception Point，TRP)、控制器，在此并不限定。
终端：可以是无线终端也可以是有线终端，无线终端可以是指一种具有无线收发功能的设备，可以部署在陆地上，包括室内或室外、手持或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。终端可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(Virtual Reality，VR)终端、增强现实(Augmented Reality，AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等，在此不作限定。可以理解的是，本申请实施例中，终端也可以称为用户设备(user equipment，UE)。
波束管理：是毫米波的协议基本特性，在TR38.802中，波束管理的关键过程被定义：获取和维护上下行数据发送和接收波束集合的L1/L2过程，包括波束确定，波束测量，波束扫描和波束上报。1)波束确定是指信号发送接收点(Transmitting Receiving pair，TRP)或用户设备(user equipment，UE)选择合适的发送接收波束的过程。UE端的需求为：UE在接收到网侧的毫米波波束后进行对齐过程，包括下行波束和上行波束选择，最终选择最优波束，UE需要满足波束互易性。2)波束测量是指UE从网侧接收到的赋形信号，信号内包括波束的信息，UE端的需求为：可正确测量网络的波束成形的信号，可正确上报波束测量信号，可根据测量结果执行波束管理的其他动作。3)波束扫描指在一个空间区域内，波束在一定时间间隔内以预定的方式发送和/或接收。UE端的需求为：UE可以在一定时间内对波束进行扫描，并将扫描结果正确处理。4)波束上报指UE基于波束测量上报赋形信号的信息。UE端的需求为：UE可在不同状态下根据网侧要求上报测量信息，并在网侧回应后作出相应的动作。
现有技术中，一般会在UE端设置两个天线阵列，每个阵列分别打出一个波束，且设置两个波束的极化方式不同，两个波束的波束方向相同。这种设置方式没有考虑具 体的业务场景、信道条件和基站调度情况，实现形式单一。由于两个波束的波束方向总是一样的，因此，当其中一个方向的波束接收失败时，另外一个波束也会同时失败，从而不利于链路的稳定性和鲁棒性。另外，现有技术中没有考虑到信道的极化特征，比如：在某些场景下，垂直极化比水平极化的波束对应参考信号接收功率(Reference Signal Receiving Power，RSRP)高很多(或反之)，这时候信号差的极化方式很难正常工作。现有技术中也没有考虑基站调度信息rank和信道质量指示CQI的值、如果网络和信道确定的rank是单流的，那同时打出2个波束也没有必要。综上可知，现有技术的实现形式单一，没有考虑基站调度信息、信道质量等对波束配置的要求，从而使得波束配置与具体业务场景不适配，影响整个通信链路的稳定性。
针对现有技术中存在的问题，本申请综合考虑了业务场景，通过确定基站调度信息rank，以及确定波达角度功率谱；根据波达角度功率谱确定峰值信息；根据峰值信息，确定符合功率条件的波束方向；根据预设的筛选条件，从符合功率条件的波束方向中选择出至少一个待选波束方向；根据基站调度信息rank、信道质量指示CQI的值、波达角功率谱，从待选波束方向中确定终端的目标波束方向。从而使得终端侧的波束配置方式更加灵活，能够满足不同的业务场景需求，提高通信链路的稳定性。
图2为本申请一实施例提供的波束配置方法的流程示意图，如图2所示，本实施例可以包括：
步骤S101、确定基站调度信息rank，以及确定波达角度功率谱。
本实施例中，终端侧可以直接从基站侧获取到基站调度信息rank。由于基站的调度信息是预先配置好的，因此，终端侧也可以通过查询基站的配置参数来获取基站调度信息rank。
本实施例中，终端侧可以在P1阶段和/或P3阶段的波束扫描时获取波达角度功率谱。具体地，以P3阶段(P3阶段时，网络设备的波束固定不变)为例进行详细说明。图3为本申请实施例提供的波达角度功率谱的获取原理示意图，如图3所示，在一预设时段内，网络设备侧的波束方向固定，在该预设时段内，控制终端侧按照预设角度间隔调整波束的方向。然后在每个波束方向上记录接收到的参考信号的功率，得到终端的波达角功率谱。具体地，
本实施例中，终端还可以通过非相干的信道估计获取波达角度功率谱。具体地，由于波达角度功率与信道信号衰落成相关关系，因此可以根据信道信号情况估算出波达角功率谱。
步骤S102、根据波达角度功率谱确定峰值信息。
本实施例中，可以通过步骤S101获取的波达角度功率谱提取出对应的峰值信息，峰值信息可以包括：各个峰值功率、最大峰值功率，以及相邻峰值功率之间的角度距离。
具体地，图4为本申请实施例提供的一场景下的波达角度功率谱的示意图；如图4所示，在直射场景(Line of Sight，LoS)和强反射场景下，各个峰值功率之间的功率值相差较大，峰值功率之间的角度距离较小。图5为本申请实施例提供的另一场景下的波达角度功率谱的示意图；如图5所示，在复杂反射，散射和遮挡场景下，各个峰值功率之间的功率值相差较小，各个峰值之间的角度距离较大。参见图4、图5， 可以从波达角度功率谱中直接提取出各个峰值功率、最大峰值功率，以及相邻峰值功率之间的角度距离。
步骤S103、根据峰值信息，确定符合功率条件的波束方向。
本实施例中，基于波达角功率谱获取峰值信息，然后根据峰值信息，找出所有符合功率条件的峰值功率对应的角度，根据该角度确定波束方向。
本实施例中，峰值信息可以包括：各个峰值功率、最大峰值功率，以及相邻峰值功率之间的角度距离。可选地，功率条件包括：
1)满足峰值功率大于基站下发给终端的RRC高层参数RACH-ConfigCommon中的rsrp-ThresholdSSB；
2)峰值功率与最大峰值功率的差值的绝对值小于等于第一预设阈值；
3)相邻峰值功率之间的角度距离大于终端的波束宽度的峰值功率所对应的波束方向。
需要说明的是，本实施例对第一预设阈值的具体取值不予限定。在不同的应用场景或者业务需求下，可以调整第一预设阈值的大小。本实施例中，可以设置第一预设阈值为10dB。
具体地，参见图4、图5，在图4中有一个符合所有功率条件的峰值功率，在图5中存在两个符合所有功率条件的峰值功率。记录下符合所有功率条件的峰值功率的波束方向。
步骤S104、根据预设的筛选条件，从符合功率条件的波束方向中选择出至少一个待选波束方向。
本实施例中，可以根据终端支持的波束能力，从符合功率条件的波束方向中选择出至少一个待选波束方向。
可选地，根据终端同时支持的波束数目上限值、符合功率条件的波束数目，确定待选波束的数目；其中，待选波束的数目为终端同时支持的波束数目上限值和符合功率条件的波束数目中的最小值；根据待选波束的数目，按照功率从高到底的顺序，从符合功率条件的波束方向中选择出待选波束方向。
具体地，假设符合功率条件的峰值功率数目为B，终端能够同时支持的最大波束数目是X，则令A＝min(X,B)，其中，A为待选波束的数目。
步骤S105、根据基站调度信息rank、信道质量指示(Channel State Indicator，CQI)的值、波达角功率谱，从待选波束方向中确定终端的目标波束方向。
本实施例中，可以在选择目标波束方向时，综合考虑基站调度信息rank、信道质量指示CQI的值。例如，根据基站调度信息rank、信道质量指示CQI的值确定选择的待选波束数量，然后基于波达角功率谱，从按照功率从高到低的顺序选择相应数目的待选波束方向作为终端的目标波束方向。
本实施例中，基于网络设备(基站)侧的调取情况和信道质量，来灵活第选择波束数量，从而可以选择最佳的通道数，降低传输功耗。
本实施例，通过确定基站调度信息rank，以及确定波达角度功率谱；根据峰值信息，确定符合功率条件的波束方向；根据预设的筛选条件，从符合功率条件的波束方向中选择出至少一个待选波束方向；根据基站调度信息rank、信道质量指示CQI的值、 波达角功率谱，从待选波束方向中确定终端的目标波束方向。从而使得终端侧的波束配置方式更加灵活，能够满足不同的业务场景需求，提高通信链路的稳定性。
在一可能的实施例中，在步骤S105之后，还可以根据水平极化和垂直极化的功率关系，确定目标波束方向上的极化方式。
本实施例中，在目标波束方向上，分别按照水平极化方式和垂直极化方式来接收基站发送的参考信号，然后依据参考信号的功率大小决定使用的极化方式。
可选地，在目标波束方向上分别采用垂直极化和水平极化方式接收基站发送的参考信号；获取垂直极化方向上参考信号的接收功率RSRP_{V}和水平极化方向上参考信号的接收功率RSRP{H}；根据max(RSRP_{H},RSRP_{V})，确定目标波束方向的极化方式。若垂直极化方式下接收功率更大，则将目标波束方向的极化方式设置为垂直极化。若水平极化方式下接收功率更大，则将目标波束方向的极化方式设置为水平极化。
示例性的，图6为本申请提供的波束配置方法的综合流程示意图，如图6所示，可以包括：
步骤1：获取波达角度功率谱。
步骤2：根据波达角度功率谱，确定符合功率条件的波束方向。
本实施例中，根据终端同时支持的波束数目上限值、符合功率条件的波束数目，确定待选波束的数目；其中，待选波束的数目为终端同时支持的波束数目上限值和符合功率条件的波束数目中的最小值；根据待选波束的数目，按照功率从高到底的顺序，从符合功率条件的波束方向中选择出待选波束方向。
步骤3：判断基站调度信息rank是否为1，且信道质量指示CQI的值是否大于15；若基站调度信息rank为1，且信道质量指示CQI的值是否大于15，则执行步骤4；否则执行步骤7。
步骤4：选择功率最强的待选波束方向作为目标波束方向。
步骤5：在目标波束方向上分别用垂直极化和水平极化方式接收基站发送的参考信号。
步骤6：选择参考信号强度大的极化方式作为目标波束方向上的极化方式，结束流程。
步骤7：判断符合功率条件的波束方向的数量是否大于1，若等于1，则执行步骤8；若大于1，则执行步骤10。
步骤8：判断垂直极化和水平极化方式接收基站发送的参考信号之差的绝对值是否大于或等于10dB；若否，则执行步骤11；若是，则执行步骤9。
步骤9：在目标波束方向上设置第一波束和第二波束；其中，第一波束方向和第二波束方向相同，且第一波束方向和第二波束方向的极化方式不同；向基站上报rank的值为1，并在基站调度信息rank的值为1时，选择第一波束方向或者第二波束方向中的任一个波束方向作为目标波束方向；在目标波束方向上分别用垂直极化和水平极化方式接收基站发送的参考信号，选择参考信号强度大的极化方式作为目标波束方向上的极化方式，结束流程。
步骤10、将所有待选波束方向作为目标波束方向，在每个目标波束方向上分别采用垂直极化和水平极化方式接收基站发送的参考信号，选择参考信号强度大的极化方 式作为目标波束方向上的极化方式，结束流程。
步骤11、在目标波束方向上设置第一波束和第二波束；其中，第一波束方向和第二波束方向相同；当第一波束方向的极化方式垂直极化时，设置第二波束方向的极化方式为水平极化；当第一波束方向的极化方式为水平极化时，设置第二波束方向的极化方式为垂直极化。
需要说明的是，在步骤3中，本实施例设置信道质量指示CQI的值的判别标准为15，在实际应用中，可以根据具体的应用场景设置不同的值。在步骤8中，本实施例设置了判断垂直极化和水平极化方式接收基站发送的参考信号之差的绝对值为10dB，在实际应用中，可以根据具体的应用场景设置不同的值。本实施例不限定具体参数的数值设置。
本实施例中，通过对波束方向和波束的极化方式的灵活配置，可以降低功耗，提高UE传输速率；以及降低链路和波束失败的概率。通过考虑网络调度情况和信道质量，来区分波束数量，可以灵活选择通道数目，降低功耗。当采用两个波束的时候，可以根据信道质量，采用不同方向的波束，从而有效降低波束故障恢复失败的概率，特别是在UE运动的情况下。当采用两个波束的时候，由于根据信道质量，采用了灵活的极化配置，因此可以提高UE的传输速率，增大流数。
本实施例，通过确定基站调度信息rank，以及确定波达角度功率谱；根据波达角度功率谱确定峰值信息；根据峰值信息，确定符合功率条件的波束方向；根据预设的筛选条件，从符合功率条件的波束方向中选择出至少一个待选波束方向；根据基站调度信息rank、信道质量指示CQI的值、波达角功率谱，从待选波束方向中确定终端的目标波束方向。从而使得终端侧的波束配置方式更加灵活，能够满足不同的业务场景需求，提高通信链路的稳定性。

步骤S205、若基站调度信息rank的值为1，且信道质量指示CQI的值大于第二预设阈值时，则选择功率最强的待选波束方向作为目标波束方向。
本实施例中，当基站为调度单流，且信号质量指示CQI的值大于第二预设阈值，则基于选择功率最强的待选波束方向作为目标波束方向。这是由于当基站为调度单流，且信号质量较佳时，本身通信链路的稳定性就很好，此时选择功率最强的待选波束方向即可稳定地接收到基站发送的信号。
需要说明的是，本实施例对第二预设阈值的具体取值不予限定。在不同的应用场 景或者业务需求下，可以调整第二预设阈值的大小。本实施例中，可以设置第二预设阈值为15。

在一种可能的实施方式中，若RSRP_{V}和RSRP{H}的差值的绝对值大于第三预设阈值，则在目标波束方向上设置第一波束和第二波束；其中，第一波束方向和第二波 束方向相同，且第一波束方向和第二波束方向的极化方式不同；向基站上报rank的值为1，并在基站调度信息rank的值为1时，选择第一波束方向或者第二波束方向中的任一个波束方向作为目标波束方向；根据max(RSRP_{H},RSRP_{V})，确定目标波束方向的极化方式。若垂直极化方式下接收功率更大，则将目标波束方向的极化方式设置为垂直极化。若水平极化方式下接收功率更大，则将目标波束方向的极化方式设置为水平极化。
