Abstract

本发明实施例提供一种信道测量的方法和装置，涉及通信领域，能够解决UL信道测量过程中AP可能无法接收到STA发送的信道探测消息和UL信道测量执行过程时间开销大的问题。其方法为：AP发送信道测量通知消息，信道测量通知消息包括STA指示和待测量信道指示；AP接收M个STA发送的信道探测信号，M个需测量信道的STA分为W个分组，且同一分组里的N个STA在V个待测量的子信道中的同一子信道上同时发送信道探测信号，信道探测信号包含多个子载波，且每Ng个连续子载波为一组子载波，每个分组里的每个STA在每组子载波中占用位置固定的一个子载波，且同一分组里的N个STA在同一组子载波中占用的子载波互不相同。本发明实施例用于窄带或宽带信道测量。
