Claim Text:
1. A method for receiving data in a wireless local area network, performed by a receiver, the method comprising: receiving a signal field that is mapped onto a first binary phase shift keying (BPSK) constellation; receiving a first Very High Throughput Signal (VHT-SIG) field that is mapped onto the first BPSK constellation; and receiving a second VHT-SIG field that is mapped onto 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 VHT-SIG field includes an indicator indicating Single User-Multiple Input Multiple Output (SU-MIMO) transmission or multi user-MIMO (MU-MIMO) transmission, and the second VHT-SIG field includes a cyclic redundancy check (CRC) for the first and second VHT-SIG fields.
