Abstract

A technique for multiple receiver aggregation that allows for multiple immediate responses of acknowledgements or block acknowledgements. The technique uses a spoofed network allocation vector (NAV) (124) implemented within an aggregate's PLCP header (112) to protect the aggregate and all of the immediate responses from multiple receivers. The immediate responses are scheduled, the information indicating the scheduled offset time and granted transmission duration for response of each receiver being included in the physical sublayer data unit (PSDU) headers within the aggregate.
