1. A communication device for transmitting a physical layer protocol data unit, PPDU, to one or more receiving devices, wherein the communication device comprises:
a processor configured to:
receive a trigger frame in a first PPDU;
obtain a sequence of disregard bits of a universal signal, U-SIG, field in the first PPDU, wherein the sequence of disregard bits comprises at least one bit set to 0; and
copy the sequence of disregard bits into the U-SIG field of a second PPDU; and
a transmitter configured to transmit the second PPDU, wherein the second PPDU comprises the sequence of disregard bits.
