Claim 13:
14. A non-transitory computer readable medium storing a program used for transmitting an uplink Orthogonal Frequency Division Multiple Access (OFDMA) physical layer convergence protocol data unit (PPDU) in a bandwidth of plurality of fundamental channels, wherein the OFDMA PPDU comprises a data portion and a common signaling portion, and the common signaling portion comprises a legacy preamble and a high efficient signal part A (HE-SIG-A), and the program, when executed by at least one processor, causes a computing device to perform following operations:
sending the common signaling portion of the uplink OFDMA PPDU only on multiple fundamental channels, wherein an allocated frequency resource unit (RU) for the data portion of the uplink OFDMAPPDU is located across the multiple fundamental channels of the plurality of fundamental channels and the bandwidth comprises at least one fundamental channel other than the multiple fundamental channels; and
sending the data portion of the uplink OFDMA PPDU on the RU.
