The HE communication station may communicate 4× 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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"High-efficiency (HE) communication station and method for communicating longer duration OFDM symbols within 40 MHz and 80 MHz bandwidth","description":"Embodiments of a high-efficiency (HE) communication station and method for HE communication in a wireless network are generally described herein.
