Embodiment Construction

[0018] The making and using of the presently preferred embodiments are discussed in detail below. It should be appreciated, however, that the present invention provides many applicable inventive concepts that can be embodied in a wide variety of specific contexts. The specific embodiments discussed are merely illustrative of specific ways to make and use the invention, and do not limit the scope of the invention.

[0019] High Efficiency WLAN (HEW) has the potential to offer improved area throughput and cell edge performance, cooperation rather than coexistence between adjacent Basic Service Sets (BSSs), and spectral efficiency for enhanced Quality of Service / Quality of Experience (QoS / QoE) The use of modulation, such as Orthogonal Frequency Division Multiple Access (OFDMA) and its associated scheduler.

[0020] Disclosed herein are systems and methods for transmitting data in a wireless network comprising a frame having a hybrid frame format, the frame having a first portion...

Abstract

The present invention provides system and method embodiments for efficient wireless communication. In an embodiment, a method in a network element for transmitting frames of two different Fast Fourier Transform (FFT) sizes includes generating a frame comprising an OFDM of two different FFT sizes ( OFDM) symbol, wherein the frame includes a first portion and a second portion, wherein the first portion includes a first FFT size and the second portion includes a second FFT size; and transmitting the frame during a single transmission opportunity.

Description

[0001] Priority Claims and Cross References [0002] The present invention requires the following provisional filing of Application No. 61 / 903,134 filed on November 12, 2013 entitled "System and Method for High Efficiency Wireless Local Area Network Communications" , the content of which is incorporated herein by reference. technical field [0003] The present invention relates to systems and methods for wireless communications, and in particular embodiments, to systems and methods for efficient wireless local area network communications. Background technique [0004] In 2013, the Institute of Electrical and Electronics Engineers (IEEE) formed the IEEE 802.11 High Efficiency Wireless Local Area Network (WLAN) (HEW) Study Group in order to enhance the efficiency and performance of WLAN deployments. The HEW research group considers improving spectral efficiency to enhance system throughput / area in high density scenarios of access points (APs) and / or stations (STAs). However,...
