Spatial reuse transmissions in wireless local area networks (WLANs)

摘要

A first communication device in a first wireless network determines a transmit power for transmitting a first packet during a spatial reuse opportunity corresponding to a transmission in a second wireless network. Determining the transmit power includes using a spatial reuse parameter, indicative of an acceptable interference level in the second wireless network, included in a second packet transmitted by a second communication device in the second wireless network. The first communication device generates the first packet to include information to indicate to a third communication device, that is an intended receiver of the first packet, to not transmit an acknowledgment of the first packet according to a normal acknowledgment procedure during the spatial reuse opportunity. The first communication device transmits the first packet at the determined transmit power, and receives the acknowledgement from the third communication device, the acknowledgement having not been transmitted according to the normal acknowledgment procedure.
