Claim 4:
5. A method of transmitting data in a wireless network, the method comprising:
mapping first data into a first field including a first symbol that is mapped onto a first binary phase shift keying (BPSK) constellation;
mapping second data into a second field including a second symbol and a third symbol immediately after the second symbol, the second symbol being mapped onto the first BPSK constellation, and the third symbol being mapped onto a second BPSK constellation and rotated by 90° counter-clockwise relative to the second symbol, wherein the second symbol includes an indicator indicating a Single User-Multiple Input Multiple Output (SU-MIMO) PPDU or a multi user-MIMO (MU-MIMO) PPDU, and the third symbol includes a cyclic redundancy check (CRC) for the second symbol and at least a portion of the third symbol; and
transmitting the first and second fields and a training field immediately after the second field.
