Coordinated transmission methods, communication devices, access point devices and communication system

Abstract

The embodiments of the present disclosure relate to coordinated transmission methods, communication devices, access point devices and a communication system. A coordinated transmission method is applied to a first device, and comprises: under a first link, receiving a first radio frame, wherein the first radio frame identifies a restricted target wake time service period (rTWT SP), the rTWT SP comprises a first rTWT SP of a first basic service set (BSS) where the first device is located, and / or a second rTWT SP of a second BSS, and the second BSS and the first BSS are located in a same overlapping basic service set (OBSS); and, before start of the rTWT SP, or before start of the second rTWT SP, terminating a transmission operation of the first device on the first link, so as to avoid causing OBSS interference to low-latency services transmitted within the second rTWT SP. Thus, the present disclosure implements coordinated transmission in multi-AP coordination scenarios.
