Orthogonal frequency division multiple access (OFDMA) and duplication signaling within wireless communications

摘要

Communications are supported between wireless communication devices using OFDMA signaling and duplicate processing. An OFDMA frame, which includes first data intended for a first recipient device and second data intended for a second recipient device, is transmitted via a first sub-channel, and a duplicate of the OFDMA frame is transmitted via a second sub-channel. In some instances, additional duplicates of the OFDMA frame are transmitted via additional sub-channels. The OFDMA frame may be generated based on a first frequency and then down-clocked to a second frequency that corresponds to a bandwidth of one of the sub-channels. A wireless communication device configured to perform such operations may be compliant with one or more IEEE 802.11 communication standards, protocols, and/or recommended practices and may also be backward compatible with prior versions of IEEE 802.11. Different numbers of sub-channels and sub-channels of different bandwidths may be used to different times.

1. A wireless communication device comprising:
a processor configured to generate an orthogonal frequency division multiple access (OFDMA) frame that includes first data for a first other wireless communication device mapped to a first one or more sub-carriers and second data for a second other wireless communication device mapped to a second one or more sub-carriers; and a communication interface configured to transmit the OFDMA frame via a first sub-channel or channel of a frequency band and a duplicate of the OFDMA frame via a second sub-channel or channel of the frequency band to the first and second other wireless communication devices.
