Abstract:
1. A method, comprising: selecting, at an access point device, a group of two or more transceivers from a plurality of transceivers for simultaneous transmission of respective data to the access point device, wherein the group of transceivers is selected so that respective power levels of signals received, at the access point device, from any two transceivers in the group of transceivers differ by no more than a predetermined amount; generating, at the access point device, a first data unit having a first physical layer (PHY) preamble, wherein the first data unit indicates which of the plurality of transceivers belong to the group of transceivers; transmitting the first data unit to each transceiver in the group of transceivers; and generating, at the access point device, a second data unit having a second PHY preamble, wherein the second data unit includes information indicative of at least one of (i) an identifier of the group of transceivers, (ii) a time at which the group of transceivers is to transmit the respective data to the access point device, (iii) an assignment of streams to each transceiver in the group of transceivers, and (iv) an MCS to be used by each transceiver in the group of transceivers; transmitting the second data unit to each transceiver in the group of transceivers; and receiving, at the access point device, the respective data from each transceiver in the group of transceivers simultaneously via a shared wireless communication channel, wherein the respective data is transmitted responsive to the second data unit.
