摘要: The invention discloses a transmit frame format for realizing an OFDMA technology in wireless local area network, and corresponding transceiving method device. By correcting the of signaling field A existing protocol, RBALLO is added to field, so as indicate mapping relation between subcarrier user. sending terminal fills distribution information resource block A, B are sent according protocol standard, data forms on all links through precoding after independently accomplishing basic baseband signal processing. receiving reads value filed demodulating B. demodulated indication filed. device allow system dispatch multiple users, obviously improve throughput rate system, reduce access time delay users.
