SPATIAL REUSE (SR) FOR OFDMA TRANSMISSIONS IN WLAN SYSTEMS

Abstract:

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for spatial reuse in a wireless network. In an example method, a first wireless device detects an overlapping basic service set (OBSS) packet received from a second wireless device in an OBSS, decodes one or more signal fields of the OBSS packet, determines that the OBSS packet is a transmission in which one or more resource unit (RUs) are unallocated, and performs a spatial reuse (SR) transmission to one or more first stations using a number of the unallocated RUs.
