OFDMA Indication and Communication in WLANs

摘要

This disclosure relates to orthogonal frequency division multiple access (OFDMA) communication in wireless local area networks (WLANs). According to some embodiments, an indication may be transmitted to receiving devices that a first frame is an OFDMA frame. Channel information indicating allocation of bandwidth portions of the first frame to respective receiving devices may also be transmitted to the receiving devices. The first frame may be transmitted to the receiving devices, including transmitting data to each respective receiving device on the bandwidth portion(s) allocated to the respective receiving device.

主权项

1. A wireless device, comprising:
an antenna; a radio operably coupled to the antenna; and a processing element operably coupled to the radio; wherein the antenna, radio, and processing element are configured to:
transmit first information to a plurality of receiving devices over a wireless local area network (WLAN) indicating that a first frame comprises an orthogonal frequency division multiple access (OFDMA) frame;transmit channel information corresponding to the first frame to each respective receiving device of the plurality of receiving devices, wherein the channel information associated with each respective receiving device indicates a bandwidth allocation to the respective receiving device for the first frame; andtransmit the first frame, comprising transmitting data to each of the plurality of receiving devices according to the indicated bandwidth allocations.
