Description

通信波束选择方法、装置及终端 技术领域
本公开涉及通信领域，具体而言，涉及一种通信波束选择方法、装置及终端。
背景技术
天线作为辐射或接收无线电波的部件而应用于任何一个无线电系统之中，其作用是将发射机送来的高频电流(或导波)有效地转换为无线电波并传送到特定的空间区域；或者将特定的空间区域发送过来的无线电波有效地转换为高频电流而进入接收机。前者称为发射天线，后者称为接收天线，这取决于无线电系统的功能要求。
天线波束方向图是用来描述由天线所辐射出的能量与空间中任意位置的相互关系，藉由方向图可以得知由天线所辐射出来的电磁波在空间中每一个位置的相对强度或绝对强度。毫无疑问，手机天线的水平方向图要求是全向的，实际上手机天线的波束方向图并不重要，主要是在手机的使用过程中，此时手机天线的辐射特性与单天线的辐射特性是不相同的。手机天线的方向图只要求水平面近似为全向即可。
然而随着无线电技术的不断进步，各种各样的无线电业务大量涌现，而无线电业务所依托的频谱资源是有限的，面对人们对带宽需求的不断增加，传统的商业通信使用的300MHz～3GHz之间频谱资源出现了极为紧张的局面，已经无法满足未来无线通信的需求。
在未来5G无线通信中，将会采用更高的载波频率进行通信，比如28GHz、45GHz等等，这种高频信道具有自由传播损耗较大，容易被氧气吸收，受雨衰影响大等缺点，严重影响了高频通信系统的覆盖性能，与LTE系统相比，相同的覆盖区域可以获得的SINR比不同，前者比后者存在至少20dB的SINR下降，为了保证高频通信与LTE系统覆盖范围内具有近似的SINR，需要保证高频通信的天线增益。由于高频通信对应的载波频率具有更短的波长，所以可以保证单位面积上能容纳更多的天线元素，而更多的天线元素意味着可以采用波束赋形的方法来提高天线增益，从而保证高频通信的覆盖性能。
采用波束赋形的方法后，发射端可以将发射能量集中在某一方向上，而在其它方向上能量很小或者没有，也就是说，每个波束具有自身的方向性，每个波束只能覆盖到一定方向上的终端，发射端即基站需要发射多个波束才能完成全方位覆盖。当基站为某一方向上的终端发送下行信息时，将采用相应的波束承载，并且在接收端即终端需要进行接收端的波束赋形，实现定向接收，进而提高接收天线增益。通信双方通过初始的波束训练过程实现了收发波束的对准，初始波束训练过程是个相对漫长的过程，要得到最佳的波束训练效果，需要遍历所有收发波束对，以找到性能最优的收发波束方向作为通信波束。
但通信过程中，由于终端的移动，收发波束将会出现变化，典型的如由于终端的旋转，原上行优选发射波束及下行优选接收波束将发生变化，如果终端仍然采用原上行优选发射 波束向基站发送上行数据，基站将无法收到，相对应的，终端通过下行优选接收波束也无法接收到基站的下行数据。如果无法快速的发现相关变化，并识别出新的优选收发波束，将可能导致业务中断，严重影响终端在高频通信中的通信质量。
针对相关技术中终端移动导致通信质量差的问题，目前还没有有效地解决方案。

下面结合本公开可选实施例进行详细说明。
在本公开可选实施例中，上述天线以终端中的天线为例，以下将上述天线代称为终端。本公开可选实施例提供了一种终端中通信波束的选择方法以实现高频通信，在本方法中，当终端发生旋转或移动导致通信波束(例如：上行优选发射波束及下行优先接收波束)发生变化时，终端根据自身旋转角度的计算，主动选择旋转后相对最优的上行优选发射波束及下行优选接收波束，从而保证当前终端的通信质量，避免重新进行初始的波束训练，进而避免业务的中断。
在本可选实施例中，检测到终端旋转后，根据终端的旋转角度，主动选择旋转后最优 的上行发射波束以及下行接收波束，使终端和基站的高频通信质量得以保持。
在本可选实施例中，在当前已经完成初始波束训练后，建立了良好的通信链路的情况下，得到通信波束集合，并记录当前终端的上行优选波束以及下行优选波束作为参考基准点。若在通信过程中，终端发生了角度方向的移动，则迅速计算出终端偏离的角度和方向。根据用户偏离的角度和方向的值，在通信波束集合中，根据先前记录的上行优选波束以及下行优选波束参考基准点，和当前用户偏离的角度和方向，选择新的上行优选波束以及下行优选波束。同时更新此上行优选波束以及下行优选波束为新的参考基准点。
在本可选实施例中，还公开了一种终端中通信波束选择的装置以实现高频通信，该装置包括：角度方向计算模块，最优波束选择模块，其中，
角度方向计算模块，用于计算当前的角度和方向以及终端旋转后偏离的角度方向；其中，角度方向计算模块依据于加速度，陀螺仪等传感器，但不限于加速度，陀螺仪传感器。可以是任何能获取到方向信息的模块。
最优波束选择模块，用于根据终端旋转的角度和方向，计算出天线的调整方向，进而选择最优的上行发射波束以及最优的下行接收波束。
当终端与基站建立通信后，若终端发生移动，导致天线的角度方向变化，信道质量变差，则终端根据终端移动的角度和方向变化，自动调整上行发射波束以及下行接收波束，完成天线波束的切换，保证通信质量。
图8是根据本公开可选实施例的通信波束选择方法的示意图，如图8所示，终端UE通过初始优选训练，选择了当前最优的上行发送波束，建立了通信链路，在通信过程中，UE发生了移动，导致当前的上行发送波束已经不再是最优的上行发送波束，进而根据终端移动的方向，角度，切换到临近的上行发送波束，此时临近的上行发送波束为最优波束。UE通过新的最优上行发送波束进行上行数据的发送。
图9是根据本公开可选实施例的通信波束选择的示意图一，如图9所示，基站和UE通过初试优选训练，已经选择了第二个通信波束(如图9中阴影所示)为优选的上行发送波束，建立了当前的通信链路。图10是根据本公开可选实施例的通信波束选择的示意图二，如图10所示，当终端发生移动后，原来的第二个上行发送波束已经不再是最优的上行发送波束，它和基站的下行波束已经不再匹配为最优了，此时，第三个上行发送波束(如图10中阴影所示)与基站侧的下行波束更为匹配，因此UE选择第三个上行发送波束进行上行数据的发送，与当前的下行波束成为最优匹配，以保证通信质量不下降。
在本可选实施例中，当终端发生旋转，导致上行优选发射波束及下行优先接收波束发生变化时，终端根据自身旋转角度的计算，主动选择旋转后相对最优的上行优选发射波束及下行优选接收波束，从而保证当前终端的通信质量，避免重新进行初始的波束训练，进而避免业务的中断。
