Abstract
A method and apparatus for communication in a network of WLAN overlapping basic service set (OBSS) are disclosed. A station or an access point may indicate its interference reporting and inter-BSS coordination capabilities in a message. At least one of quality of service (QoS) settings, transmission opportunity (TXOP), restricted access window (RAW) or beacon subinterval schedules, or traffic indication map (TIM) or uplink access window assignment may be coordinated. The station may receive a request for interference measurements on the basic service set (BSS) of the station or neighboring BSSs that the station can overhear. The station may transmit an interference measurement report to an access point. The coordination may be performed based on the interference measurement report. Furthermore, STAs may transmit channel or sector preferences to APs and receive channel or sector assignments.
