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.

Abstract translation: 公开了一种WLAN重叠基本业务集（OBSS）网络中的通信方法和装置。 站或接入点可以在消息中指示其干扰报告和BSS间协调能力。 可以协调服务质量（QoS）设置，传输机会（TXOP），受限访问窗口（RAW）或信标子区间调度或业务指示映射（TIM）或上行链路接入窗口分配中的至少一个。 该站可以接收对该站可以听到的站或相邻BSS的基本业务集（BSS）的干扰测量请求。 该站可以向接入点发送干扰测量报告。 可以基于干扰测量报告来执行协调。 此外，STA可以向AP发送信道或扇区偏好并且接收信道或扇区分配。
