Claim:
1. A method for simultaneous communication in a wireless local area network that includes a first communication device and a plurality of second communication devices, the method comprising: forming an orthogonal frequency division multiple access (OFDMA) group that includes two or more second communication devices of the plurality of second devices; allocating, at the first communication device, respective sub-channel blocks to the two or more second communication devices, including providing, from the first communication device to the two or more second communication devices, indications of the respective sub-channel blocks allocated to the two or more second communication devices; and performing, at the first communication device, one of (i) transmitting a physical layer (PHY) data unit to the two or more second communication devices or (ii) receiving a physical layer (PHY) from the two or more second communication devices, wherein the PHY data unit includes respective orthogonal frequency division multiplexing (OFDM) data units transmitted using respective sub-channel blocks allocated to the two or more second communication devices.
