Abstract
In wireless communications, a station associated with a first wireless network may perform early detection of a high-efficiency (HE) frame for spatial reuse (SR). The station may determine a received power of a legacy preamble of the HE frame when the frame is associated with a second wireless network. The station may reduce the received power by a predetermined value. The station may initiate an SR transmission, when the reduced power is less than an overlapping basic service set (OBSS) packet detection level. The station may obtain an SR parameter associated with a second station, where the SR parameter is based on a transmission power level and an interference level at the second station, and initiate an SR transmission, based on the SR parameter and the reduced power. Other methods, apparatus, and computer-readable media are also disclosed.
