Claim 3:
4. The communication device according to claim 3, wherein setting the value of the first disregard bits sequence to the sequence comprising at least one ‘0’ bit comprises:
setting the first disregard bits sequence of a multi-user (MU) PPDU to one of the sequences in the set {‘00101’, ‘00110’, ‘01001’, ‘01111’, ‘10011’, ‘10101’, ‘11000’, ‘10110’}; or
setting the first disregard bits sequence of a trigger-based (TB) PPDU for a first U-SIG symbol to one of the sequences in the set {‘010010’, ‘010011’, ‘010100’, ‘010101’, ‘011100’, ‘011101’, ‘011110’, ‘011111’, ‘100101’, ‘100010’, ‘110100’, ‘111000’, ‘111001’}; or
setting the first disregard bits sequence of a TB PPDU for a second U-SIG symbol to one of the sequences in the set {‘01001’, ‘01101’, ‘01111’, ‘11010’, ‘11011’, ‘11101’, ‘11110’, ‘11111’}; or
setting a single global value of the first disregard bits sequence within the first U-SIG symbol for different bandwidth (BW) values for a TB PPDU, and the first disregard bits sequence is set as ‘011110’ in binary; or
setting a single global value of the first disregard bits in the second U-SIG symbol for different bandwidth values for a TB PPDU, and the first disregard bits sequence is set as ‘01001’ or ‘11110’ in binary.
