Enhanced resource unit allocation schemes for ofdma transmission in wlan

A wireless communication device comprising:

• a processor that causes the wireless communication device to allocate a first resource unit (RU) and a second RU to a receive station for an Orthogonal frequency-division multiple access (OFDMA) transmission;
• and
• a transceiver, configured to:
• setting a common field of preamble of a Physical Layer Convergence Protocol (PLCP) protocol data unit (PPDU) to indicate multiple RU allocation to the receive station;
• encode data associated with the first RU and encode data associated with the second RU using a Low Density Parity Check (LDPC) encoder;
• and
• transmit the PPDU in the OFDMA transmission, wherein the PPDU comprises the data associated with the first RU and the data associated with the second RU.

A method of wireless communication, the method comprising:

• allocating a first resource unit (RU) and a second RU for an Orthogonal frequency-division multiple access (OFDMA) transmission;
• setting a common field of preamble of a Physical Layer Convergence Protocol (PLCP) protocol data unit (PPDU) to indicate multiple RU allocation to the receive station;
• performing LDPC tone mapping on data associated with the first RU and data associated with the second RU using an LDPC tone mapper;
• and
• transmit the PPDU in the OFDMA transmission, wherein the PPDU comprises the data associated with the first RU and the data associated with the second RU.
