Claim:
1. A method, comprising: measuring, at a first communication device, respective receive power levels of signals transmitted by second communication devices in a plurality of second communication devices; selecting, at a first communication device, a group of two or more second communication devices from the plurality of second communication devices for simultaneous transmission of respective data to the first communication device, wherein the group is selected i) so that respective measured receive power levels of the signals from any two second communication devices in the group differ by no more than a predetermined amount, and ii) without instructing any second communication device in the group to adjust a transmit signal power level; generating, at the first communication device, a communication frame that includes information indicative of the group and at least one of (i) a time at which the group of transceivers is to simultaneously transmit respective data to the access point device, (ii) an assignment of streams to each second communication device in the group, and (iii) a respective modulation and coding scheme (MCS) to be used by each second communication device in the group; transmitting, with the first communication device, the communication frame to prompt the group to simultaneously transmit respective data to the first communication device; and receiving, at the first communication device, the respective data from each second communication device in the group simultaneously via a shared wireless communication channel, wherein the respective data is transmitted responsive to the communication frame.
