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 22):
An apparatus, comprising:\n a wireless network interface device having one or more integrated circuit (IC) devices, the wireless network interface device associated with a first communication device, wherein the wireless network interface device includes a media access control layer (MAC) processing unit implemented on the one or more IC devices, the MAC processing unit configured to determine an assignment of a first orthogonal frequency division multiplex (OFDM) tone block within a wireless local area network (WLAN) communication channel to the first communication device for an uplink orthogonal frequency division multiple access (OFDMA) transmission, wherein:\n the first OFDM tone block spans a first frequency bandwidth less than or equal to 10 MHz, and \n the first OFDM tone block is within a subchannel that spans a second frequency bandwidth of 20 MHz; and \n wherein the wireless network interface device further includes a physical layer (PHY) processing unit implemented on the one or more IC devices and coupled to the MAC processing unit, the PHY processing unit configured to generate a first PHY data unit for transmission on the WLAN communication channel using data tones and pilot tones within the first OFDM tone block, including:\n generating a preamble portion of the first PHY data unit, the preamble portion including a legacy signal field spanning the second frequency bandwidth, and \n generating a data portion of the first PHY data unit, the data portion including data modulated to the first OFDM tone block, the data portion of the first PHY data unit spanning the first frequency bandwidth; \n wherein the PHY processing unit is further configured to transmit the first PHY data unit simultaneously with a transmission of a second PHY data unit in the WLAN communication channel by a second communication device as part of the uplink OFDMA transmission, wherein a preamble portion of the second PHY data unit spans the subchannel, and wherein a data portion of the second PHY data unit spans a bandwidth of a second OFDM tone block within the subchannel.
