Abstract:
A communication device assigns i) a first orthogonal frequency division multiplex (OFDM) tone block for a communication channel to a first communication device, and ii) a second OFDM tone block to a second communication device. The first OFDM tone block and the second OFDM block each span less than or equal to 10 MHz, and are both within a subchannel that spans a 20 MHz. The communication device generates an orthogonal frequency division multiple access (OFDMA) physical layer (PHY) data unit for transmission in the communication channel. The OFDMA PHY data unit is generated to include: a legacy preamble portion having legacy signal field that spans the subchannel; and a data portion that includes i) first data for the first communication device modulated to the first OFDM tone block, and second data for the second communication device modulated to the second OFDM tone block.

Claim (Index 1):
A method, comprising:\n assigning, at a communication device, a plurality of different orthogonal frequency division multiplex (OFDM) tone blocks for a wireless local area network (WLAN) communication channel to a plurality of communication devices, including assigning a first OFDM tone block to a first communication device, and assigning a second OFDM tone block to a second communication device, wherein:\n the first OFDM tone block spans a first frequency bandwidth less than or equal to 10 MHz, \n the first OFDM tone block is within a subchannel that spans a frequency bandwidth of 20 MHz, \n the second OFDM tone block spans a second frequency bandwidth less than or equal to 10 MHz, and \n the second OFDM tone block is within the subchannel; and \n generating, at the communication device, an orthogonal frequency division multiple access (OFDMA) physical layer (PHY) data unit for transmission in the WLAN communication channel, including:\n generating a PHY preamble portion of the OFDMA PHY data unit that spans at least the subchannel, the PHY preamble portion including a legacy preamble portion that spans at least the subchannel, wherein the legacy preamble portion includes a legacy signal field that spans the subchannel, and \n generating a data portion of the OFDMA PHY data unit, the data portion including respective independent data for the plurality of devices modulated to respective OFDM tone blocks, including i) first data for the first communication device modulated to the first OFDM tone block within the subchannel, and second data for the second communication device modulated to the second OFDM tone block within the subchannel.
