Abstract (en)
[origin: WO2015195460A1] Embodiments of a high-efficiency (HE) communication station and method for HE communication in a wireless network are generally described herein. The HE communication station may communicate 4x longer-duration OFDM symbols on channel resources in accordance with an OFDMA technique. The channel resources may comprise one or more resource allocation units with each resource allocation unit having a predetermined number of data subcarriers. The station may also configure the resource allocation units in accordance with one of a plurality of subcarrier allocations for one of a plurality of interleaver configurations. The station may process the longer-duration OFDM symbols with a 512-point fast-Fourier Transform (FFT) for communication over a 40 MHz channel bandwidth comprising a 40 MHz resource allocation unit, and with a 1024-point FFT for communication over an 80 MHz channel bandwidth comprising either two 40 MHz resource allocation units or one 80 MHz resource allocation unit.
