Abstract:
1. A method for wireless local area network, the method comprising, generating a Very High Throughput Signal A (VHT-SIG-A) field; generating a VHT Signal B (VHT-SIG-B) field; and transmitting the VHT-SIG-A field and the VHT-SIG-B field over an operating band to at least one receiver, a bandwidth of the operating band being a multiple of 20 MHz, wherein the VHT-SIG-A field is repeatedly transmitted over each 20 MHz bandwidth of the operating band in more than one orthogonal frequency division multiplexing (OFDM) symbol, wherein the VHT-SIG-B field is transmitted over the entire bandwidth of the operating band in one OFDM symbol, wherein generating the VHT-SIG-B field includes repeating a SIG-B a predetermined number of times in accordance with the bandwidth of the operating band, wherein the SIG-B includes bit information, wherein the predetermined number of times increases as the bandwidth of the operating band increases, wherein the bit information includes information specific to each receiver, wherein the VHT-SIG-B field includes a plurality of SIG-Bs each of which is transmitted via a corresponding stream, and the plurality of SIG-Bs is obtained by repeating the SIG-B the predetermined number of times in accordance with the bandwidth of the operating band, and wherein a number of the least one stream is determined based on a number of transmit antennas.
