Abstract

A unified channel contention scheme is proposed such that spatial reuse can be enabled by a wireless station (101) when a basic service set, hereinafter BSS, color of a received signal cannot be resolved. If the detected frame is an intra-BSS frame, then the STA should not contend the channel for the PPDU duration. If the detected frame is an inter-BSS frame, then the wireless station (101) uses OBSS Packet Detection level as a clear channel assessment level, hereinafter CCA level, for channel contention. Furthermore, when BSS color cannot be resolved, channel contention schemes for WiFi signal and non-WiFi signal are differentiated. If the received signal is detected as WiFi signal, then the wireless station (101) uses WiFi-SIG Detection level as the CCA level for channel contention. If the received signal is detected as non-WiFi signal, then the wireless station (101) uses Non-WiFi-SIG Detection level as the CCA level for channel contention.
