Abstract
The deferral mechanism described herein may improve medium reuse in a wireless network with transmit power imbalances. For example, in one embodiment, an apparatus employing the deferral mechanism described herein may comprise a receiver to sense a data unit transmitted on a medium associated with the wireless network, wherein the data unit may comprise information indicating a transmit power associated therewith. Furthermore, the apparatus may comprise one or more processors to initiate a transmission on the medium associated with the wireless network if the apparatus is not an intended receiver of the sensed data unit, the transmit power associated with the data unit exceeds a transmit power associated with the apparatus, and a received power associated with the data unit does not equal or exceed a clear channel assessment threshold plus a difference between the transmit power associated with the data unit and the transmit power associated with the apparatus.
