Description

OAM波束传输方法、装置、用户设备及存储介质 技术领域
本公开涉及通信技术领域，尤其涉及一种OAM波束传输方法、装置、用户设备及存储介质。
背景技术
为了解决频谱资源短缺的问题，通常会利用UCA(Uniform circular array，均匀圆形相控天线阵列)来建立OAM(Orbital angular momentum，轨道角动量)通信系统。其中，在OAM通信系统中，不同模态的OAM波束会对应不同的发散角，不同发散角对应的最优接收半径不同，因此，当利用一个接收阵列接收多个不同发散角下的OAM波束时，会影响到OAM波束的接收质量。
相关技术中，方法一、通常会在收发端均设置UCA，其中，接收阵列与发送阵列一一对应，每个接收阵列的接收半径用于作为某一发散角对应的最优接收半径来接收该发散角下的OAM波束；方法二、通常会在发送端设置发送UCA，接收端设置一个接收阵列，基于不同OAM模态对发送UCA进行优化，实现不同OAM模式下相同发散角发送。
但是，方法一中当传输距离发生改变时，OAM波束的发散角会改变，则会影响到OAM波束的接收质量。方法二无法控制发散角在径向方向上的变化，也会影响到OAM波束的接收质量。
发明内容

综上所述，在本公开实施例提供的OAM波束传输方法之中，发送端会向接收端发送RS，然后接收该接收端基于RS反馈的信息，发送端基于接收到的信息确定发送端对应的权向量，并基于权向量调整待发送OAM信号的发散角得到调整后的OAM波束，之后，向接收端发送调整后的OAM波束。由此可知，本公开实施例中发送端在基于待发送的OAM信号发送OAM波束前，会根据接收端反馈的信息确定权向量，再基于权向量调整待发送OAM信号的发散角得到调整后的OAM波束，以使得调整后的OAM波束中能量最强的圆环匹配于接收端的接收阵列。从而，即使收发端处于移动场景，或者，发送端发送不同模态的OAM信号时，发送端每次发送的OAM波束中能量最强的圆环均会匹配于接收端的接收阵列，则确保了OAM波束的接收质量。
此外，本公开实施例之中，会通过给不同半径的发送阵列乘不同的加权系数来调整发送端发送的OAM波束的发散角，则可以确保调整后的OAM波束的发散角在径向方向上变化，从而进一步确保了OAM波束的接收质量，有效解决了共轴、移动场景下因模态及收发天线阵列的距离变化造成的OAM波束传输性能下降问题，提高了OAM波束的传输性能。
