Abstract

A station (STA) may receive, in a trigger frame in a multi-user wireless local area network (WLAN), control information for one or more sub-bands of a bandwidth available for overlapping basic service set (OBSS) spatial reuse (OBSS SR) and a transmission power parameter for the one or more sub-bands. The STA may generate a physical (PHY) layer preamble including a signal field that includes an indication of the one or more sub-bands for SR and a power threshold for the SR.
