Problems solved by technology

A high density of APs (also commonly referred to as communication controllers, controllers, etc.) and stations (also commonly referred to as users, subscribers, terminals, etc.) tends to make WLANs less efficient, especially since a low density of APs and stations is assumed when designing the original WLAN
As an example of inefficiency, currently used enhanced distributed channel access (EDCA) based media access control (MAC) schemes generally fail in environments with high AP and site densities. work effectively

Embodiment Construction

[0027] The operation of the present example embodiment and its structure are discussed in detail below. It should be appreciated, however, that the present disclosure provides many applicable inventive concepts that can be implemented in a wide variety of specific contexts. The specific embodiments discussed are merely illustrative of specific structures of the invention and specific ways for operating the invention, and do not limit the scope of the invention.

[0028] The present invention will be described with reference to example embodiments in the specific context of a communications system that uses response messages to indicate readiness for transmission reception. The present invention is applicable to standard-compliant communication systems, such as those compliant with technical standards such as Third Generation Partnership Project (3GPP), IEEE 802.11, and non-compliant communication systems that use response messages to indicate reception of transmission readines...

Abstract

A method for communicating in a wireless system includes receiving a trigger frame including a paging bitmap and resource allocation information indicating a location of a resource pool for transmitting a packet, and Figure determines whether the station is allowed to transmit the packet. If the station is allowed to transmit the packet, the method further includes: determining a location of a network resource in the resource pool based on an identifier of the station, and transmitting the packet at the location of the network resource .

Description

[0001] This application claims U.S. Nonprovisional Patent Application No. 14 / 478,756, filed September 5, 2014, entitled "System and Method for OFDMA PS-Poll Transmission" and earlier U.S. Provisional Patent Application No. 61 / 877,726, filed September 13, 2013, entitled "System and Method for OFDMA PS-Poll Transmission" Claiming priority, the contents of these two earlier applications are incorporated herein by reference. technical field [0002] The present invention relates to digital communications and, in particular embodiments, to orthogonal frequency division multiple access (OFDMA) PS-poll transmissions. Background technique [0003] The number of devices using Wireless Local Area Network (WLAN) continues to grow dramatically. WLANs enable users to connect to high-speed services without being tethered to a wired connection. WLAN is a wireless communication system based on IEEE 802.11 series technical standards. Generally, as the number of devices using the WLAN incr...
