Title:
CHANNEL SWITCHING FOR C-OFDMA TRANSMISSION IN MULTI-AP SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/141211
Kind Code:
A1
Abstract:
The present invention relates to a method performed by a shared AP in a wireless LAN system, the method comprising the steps of: allocating a first channel to first and second stations (STAs), wherein the shared AP is associated with the first and second STAs; receiving, from a sharing AP, an allocation of a second channel for transmission of coordinated orthogonal frequency division multiplexing access (C-OFDMA); and transmitting a channel switching signal that requests channel switching from the first channel to the second channel, wherein the channel switching signal is only transmitted to the first STA participating in the C-OFDMA, but not to the second STA not participating in the C-OFDMA.
