1. A method performed by a station (STA), the method comprising:
receiving, from an access point (AP), a trigger frame that solicits a Uplink Orthogonal Frequency-Divisional Multiple Access (UL OFDMA) transmission from the STA, wherein the trigger frame indicates a plurality of sub-bands and a plurality of power thresholds associated with the plurality of sub-bands, wherein the plurality of sub-bands are available for overlapping basic service set (OBSS) spatial reuse (OBSS SR) by one or more OBSS STAs; and
in response to the trigger frame, transmitting a physical (PHY) layer preamble that includes a signal field indicating the plurality of sub-bands and associated power thresholds indicated by the trigger frame, that are available for OBSS SR by the one or more OBSS STAs.
