Description

波束赋型报告传输方法、通信节点及计算机可读存储介质 技术领域
本公开涉及通信技术领域，具体涉及一种波束赋型报告传输方法，一种通信节点，以及一种计算机可读存储介质。
背景技术
随着无线局域网(Wireless Local Area Network，简称WLAN)技术的发展，无线局域网性能不断的提高，对传输的可靠性的要求也在不断提高，并且要求能够支持边缘用户。在无线局域网中，常见设备为接入点(Access Point，简称AP)以及非接入站点(non-AP Station)，其中接入点是指无线局域网用户端接入网络的设备，非接入站点又简称为站点(Station，简称STA)，是指无线局域网用户端设备。AP建立一个基本服务集(Basic Service Set，简称BSS)，STA通过扫描认证关联过程与AP关联，并与AP通信，或者STA通过AP与其他STA通信。在相关技术中，STA只能与一个AP关联，STA会对自己与相关联的AP之间的信道进行信道质量测量，并将测量结果反馈给关联的AP，AP再根据得到的测量结果进行波束赋型操作向STA发送数据。
为了提高传输效率，以及提高AP与其覆盖的边缘STA之间传输可靠性，在新一代的无线局域网中，支持多AP操作，即支持多个AP之间通过联合或者是协作等方式进行信息传输。在支持多AP操作的网络中，需要一种获取STA与多个AP之间的波束赋型结果或信道质量测量结果的机制，但在相关技术中还未包含有完善的获取机制。

在另一些实施方式中，第一接入点或者站点给一个或多个接入点发送信道测量PPDU分配了RU，每个接入点用于发送信道测量PPDU的RU索引分别为i(＝0，1，...N)；站点在与这一个或多个接入点进行波束赋型或信道测量后，向第一接入点发送波束赋型报告，其中携带的第二通信节点标识比特图中比特位i(＝0，1，...N)映射到使用RU索引为i的RU发送信道测量PPDU的接入点，当第二通信节点标识比特图中比特位j(＝0，1，...N)设置为特定值，例如设置为1，表示所述波束赋型报告中包含其与使用RU索引为j的RU发送信道测量PPDU的接入点之间的波束赋型结果/信道质量测量结果。例如，接入点i使用RU i的RU发送信道测量 PPDU，那么站点在发送的波束赋型报告中包含其与接入点i之间的波束赋型结果或信道质量测量结果时，将第二通信节点标识比特图中的比特位i的值设置为1。第一接入点在接收到该波束赋型报告时，根据第二通信节点标识比特图中的比特位i设置为1，获知其中包含目标站点与接入点i之间的波束赋型结果/信道质量测量结果，并根据比特位i在比特图中设置为1中比特位的位置获取到对应的波束赋型结果/信道质量测量结果。
在另一些实施方式中，波束赋型报告中还可以携带所承载的波束赋型结果的数目N，即用于指示该波束赋型报告中包含STA与N个AP之间的波束赋型结果或信道质量测量结果。
基于相同的技术构思，本公开实施例还提供一种计算机可读存储介质，其上存储有计算机程序，所述计算机程序被处理器执行时，所述处理器执行如上所述的波束赋型报告传输的方法。
