Abstract
The invention provides multi-user communication in a MU Uplink transmission opportunity in case of a multi-BSS environment of a wireless network. Resource units with AID=0 or 2045 are available for stations to transmit data to addressee virtual access points (VAPs) other than the VAP having initiated the TXOP. The initiating VAP receiving frames from the resources forwards them to the appropriate addressee VAPs within the same physical AP. Responses may be provided by the addressee VAPs directly to the stations or via the initiating VAP or the representative VAP. This approach increases the opportunities for the stations to access the medium in case of multiple BSSs. Better usage of the MU Uplink OFDMA transmission is also made.
