Patent ID: 8780824

Claim:
A high-throughput (HT) wideband communication unit comprising a physical layer (PHY) and a media-access control (MAC) layer capable of sending a physical service data unit (PSDU) to the PHY for transmission by the PHY, wherein the PHY is capable of transmitting a physical protocol data unit (PPDU) that includes the PSDU over up to four channels or more, wherein a channel of the up to four channels or more includes a primary channel and a secondary channel in non-contiguous portions of a spectrum and each channel is capable of transmitting orthogonal frequency division multiplexed (OFDM) symbols over a plurality of subcarriers of a wireless wideband communication, the PPDU having a frame structure including: a field indicating a bit loading per subcarrier to transmit the PPDU; a field indicating number of octets in the PSDU; and a signal field including length and rate information.
