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
statically allocating a respective primary sub-channel block to each of the two or more second communication devices, wherein the respective statically allocated primary sub-channel blocks remain allocated to the second communication devices for transmission of at least two PHY data units, anddynamically allocating at least some of remaining sub-channel blocks, that are not allocated as primary sub-channel blocks to the two or more second communication devices, among the two or more second communication devices, wherein the at least some of the remaining sub-channel blocks are dynamically allocated for transmission of each of the at least two PHY data units; 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. |
