Abstract:
1. A method for receiving control information in a wireless communication system, the method comprising: receiving a first modulation sequence in a first orthogonal frequency division multiplexing (OFDM) symbol; receiving a second modulation sequence in a second OFDM symbol; and receiving a third modulation sequence in a third OFDM symbol, wherein the first modulation sequence is generated by modulating a signal field on a first binary phase shift keying (BPSK) constellation, wherein the second modulation sequence is generated by modulating a first Very High Throughput-Signal (VHT-SIG) field on the first BPSK constellation; wherein the third modulation sequence is generated by modulating a second VHT-SIG field on a second BPSK constellation, wherein the second BSPK constellation is rotated by 90° counter-clockwise relative to the first BPSK constellation, and wherein the first OFDM symbol is contiguous with the second OFDM symbol and the second OFDM symbol is contiguous with the third OFDM symbol.
