Patent ID: 10298365

Abstract:
An orthogonal frequency division multiple access (OFDMA) frame includes a 256 tone payload. The 256 tone payload may consist of either 234 data tones when the payload is carried in a downlink transmission. The 256 tone payload may consist of 216 data tones when the payload is carried in an uplink transmission. In addition, the OFDMA frame may include one or more resource units (RUs). Each of the one or more RUs may consist of either an integer multiple of 26 data tones or an integer multiple of 24 data tones and 2 pilot tones. Another embodiment OFDMA frame comprises a symbol-based RU (SRU) that may include an integer multiple of 2 pilots tones and either an integer multiple of 24 data tones or an integer multiple of 26 data tones.
