Abstract
When a transmitter transmits a first Timing Offset Indication iDentifier (TOID) of a plurality of TOIDs representing timing offset of a frame, the transmitter determines a first codeword corresponding to the first TOID of a plurality of codewords representing a subcarrier. The transmitter allocates a busy tone to a first subcarrier that the first codeword represents. The transmitter transmits the busy tone.
