具体实施方式
下面结合本申请实施例中的附图对本申请实施例进行描述。
如图1所示，图1是本申请实施例提供的一种通信系统100的架构示意图。该通信系统100可以包括网络设备110和终端设备101～终端设备106。应理解，可以应用本申请实施例的方法的通信系统100中可以包括更多或更少的网络设备或终端设备。网络设备或终端设备可以是硬件，也可以是从功能上划分的软件或者以上二者的结合。网络设备与终端设备之间可以通过其他设备或网元通信。在该通信系统100中，网络设备110可以向终端设备101～终端设备106发送下行数据。当然，终端设备101～终端设备106也可以向网络设备110发送上行数据。终端设备101～终端设备106可以是蜂窝电话、智能电话、便携式电脑、手持通信设备、手持计算设备、卫星无线电装置、全球定位系统、掌上电脑(personal digital assistant，PDA)和/或用于在无线通信系统100上通信的任意其它适合设备等等。网络设备110可以为接入点(access point，AP)、节点B、演进型节点(environment bureau，eNB)或5G基站(next generation base station，gNB)，指在空中接口上通过一个或多个扇区与无线终端进行通信的接入网络中的设备。通信系统100可以采用公共陆地移动网络(public land mobile network，PLMN)、设备到设备(device-to-device，D2D)网络、机器到机器(machine to machine，M2M)网络、物联网(internet of things，IoT)或者其他网 络。此外，终端设备104～终端设备106也可以组成一个通信系统。在该通信系统中，终端设备105可以发送下行数据给终端设备104或终端设备106。在本申请实施例中的方法可以应用于图1所示的通信系统100中。
由于mmWave波长短、频率高，具有强衰减、易受雨衰和大气吸收的影响，因此移动性和覆盖具有很大的挑战。为了能够较好的获得发射增益和接收增益，mmWave利用窄波束进行发射和接收，这样可以较好的提高覆盖和移动性。但是，这种波束必须保证接收波束和发射波束的主瓣方向对齐才能够获得最优的增益。如图2所示，图2是本申请实施例提供的一种波束对齐的示意图。如果选择左侧的波束对，主瓣方向未对其，影响接收和发射性能。而如果选取右侧的波束对，主瓣方向可以对其，因此可以获得最优的接收增益和发射增益。
对于基站来讲，由于天线阵子较多，且天线面积较大，可以做到各个方向的波束发射增益和接收增益较均衡。而UE的天线阵子较小，且天线面板较小，各个方向的波束无法做到均衡。例如，图3(A)和图3(B)是本申请实施例提供的一种5*5天线阵列因子增益的顶面和侧面图，每个方向5扇区，总共25扇区。从图3(A)和图3(B)可以看出，法线波束(也即垂直于天线面板的波束)的方向有效全向辐射功率(effective isotropic radiated power，EIRP)性能最优，四周的波束EIRP呈下降趋势，从图3(C)也可以看出中间的法线波束EIRP，四周的波束组件降低。
在目前的技术方案中，可以针对一个发射波束，对所有的接收波束进行一次测量扫描，重复上述过程，针对其他每个发射波束，对所有的接收波束进行一次测量扫描，将测量值最优的接收波束和发射波束的波束对作为最优波束对。但是，这种方案无法保证每次使用的是UE最佳的接收波束与发射波束构成最优波束对。
如图4所示，图4是本申请实施例提供的一种波束对齐方法的流程示意图。本申请实施例中的步骤至少包括：
S401，在当前位置处通过多个接收波束接收网络设备发送的发射波束，并确定所述多个接收波束中每个接收波束的参考信号接收功率(reference signal receiving power，RSRP)。
具体的，针对网络设备的每个发射波束，在当前位置对所有的接收波束进行测量扫描，并确定每个接收波束的RSRP。
S402，根据所述RSRP，从所述多个接收波束中选取最优接收波束。
具体的，可以从所述多个接收波束中选取所述RSRP最大的接收波束作为所述最优接收波束。此时，终端设备使用该RSRP最大的接收波束与网络设备的发射波束构成最优波束对。
S403，根据所述最优接收波束，确定终端设备使用法线波束与所述发射波束对齐所需要的旋转角度和旋转方向。
具体的，终端设备可以确定所述法线波束与所述最优接收波束的相对位置；根据所述相对位置，确定所述终端设备使用所述法线波束与所述发射波束对齐所需要的所述旋转角度和所述旋转方向。也即从法线波束的位置旋转到最优接收波束的位置所需要的旋转角度和旋转方向。其中，所述法线波束为垂直于所述网络设备的天线面板的波束。
S404，根据所述旋转角度和所述旋转方向，调整所述终端设备的位置，在调整后的位置处使用所述法线波束构成与所述发射波束的最优波束对。
具体的，可以按照旋转方向和旋转角度调整所述终端设备方向和角度，进而起到调整终端设备中的天线的辐射方向和辐射角度的作用。在调整到所述旋转角度和所述旋转方向所指示的位置处时停止旋转终端设备。此时，终端设备可以使用法线波束与发射波束对齐形成最优波束对。
可选的，终端设备可以显示所述旋转角度和所述旋转方向，这样用户可以按照显示的旋转角度和旋转方向来旋转所述终端设备。示例性的，可以在终端设备的通知栏显示旋转角度和旋转方向，也可以在终端设备的显示界面的中间位置显示旋转角度和旋转方向。也可以通过提示框(例如气泡)显示旋转角度和所述旋转方向。需要说明的是，也可以通过其他方式显示旋转角度和旋转方向，此处显示方式并不限定。
例如，如图5所示，图5是本申请实施例提供的一种信息显示的示意图。在终端设备的通知栏显示->(40)，表示向右旋转40度，使得终端设备可以使用法线波束与发射波束构成最优波束对。需要说明的是，终端设备也可以向左、向前或向右任何一个方向旋转，旋转角度也可以是任何一个角度。
可选的，可以在显示所述旋转角度和所述旋转方向的时长超过预设阈值时，停止显示所述旋转角度和所述旋转方向。其中，预设阈值可以30秒或1分钟，此处并不限定。
可选的，当所述终端设备调整到所述旋转角度和所述旋转方向所指示的位置处时，终端设备显示提示信息，所述提示信息用于提示用户完成调整所述终端设备的位置。此时用户查看到提示信息时，可以停止旋转终端设备的位置，使得终端设备可以使用法线波束与发射波束构成最优波束对。
例如，如图6所示，图6是本申请实施例提供的一种波束的示意图。图6中的左边表示终端设备可以使用的接收波束的ID。其中，0号波束为法线波束(bore sight direction/peak direction)，在当前位置使用的76号波束与基站的发射波束构成最优波束对。因此，可以旋转两个波束(76号波束和0号波束)之间相对应角度，将0号波束旋转到76号波束的位置，使得UE使用0号波束与基站的发射波束构成最优波束对。该0号波束旋转到76号波束的旋转角度，即为UE需要旋转的角度。
在本申请实施例中，在当前位置处通过多个接收波束接收网络设备发送的发射波束，并根据每个接收波束的RSRP，从多个接收波束中选取最优接收波束；根据最优接收波束，确定终端设备使用法线波束与发射波束对齐所需要的旋转角度和旋转方向；根据旋转角度和旋转方向，调整终端设备的位置，在调整后的位置处使用法线波束与发射波束的构成最优波束对。通过确定从法线波束的位置旋转到最优接收波束的位置所需要的旋转角度和旋转方向，使得终端设备在调整位置后可以使用法线波束与发射波束构成最优波束对。从而不仅提高终端设备的发射增益或接收增益，而且提高了毫米波的覆盖和移动性。
