Abstract: In one embodiment, a method includes identifying a plurality of wireless devices associated with the wireless network apparatus, identifying a subset of the plurality of wireless devices based on whether the wireless devices in the subset have a probability above a threshold to yield to each other via a clear channel assessment (CCA) and whether the wireless network apparatus can decode uplink signals simultaneously transmitted by the wireless devices in the subset over a common uplink resource, assigning the subset to an uplink resource, separating each wireless device in the subset to each of a plurality of groups, and transmitting, for each group, a steered downlink message indicating the assigned uplink resource for each wireless device in the group, wherein the wireless devices in each group are assigned to different uplink resources.
