Abstract: Systems and techniques for coordinating wireless local area networking communication. An access point capable of OFDMA communication transmits to one or more stations capable of synchronous communication. Each communication frame transmitted on the uplink or downlink includes information, such as OFDM header information, Morming legacy stations not to transmit during the OFDMA transmission. The header information may be a legacy header prepended by the access point for downlink transmission, or a portion of a legacy header prepended by each of a plurality of stations for uplink transmission, with the portions being concatenated into a complete header during a simultaneous transmission. Alternatively, the header information may be a header transmitted by a designated group leader during a simultaneous transmission.
