Embodiment Construction

[0053] FIG. 1 is a functional flowchart 105 of a wireless access point adjusting frame parameters suitable for concurrent interference transmission and reception of a frame based on channel state changes according to the present invention. In a wireless architecture, frame parameters (hereinafter also referred to as coding aggressiveness) affect a major aspect of concurrent interference transmission and reception, namely the ability of a receiver to handle two or more concurrent transmissions. Another aspect that can be affected by changing frame parameters is the change in payload length. Such a receiver is part of the wireless access point and in some cases also part of the wireless end device.

[0054] By changing the coding aggressiveness so that the access point can process only one transmission, two transmissions, or multiple transmissions, the wireless access point can optimize its performance in response to dynamically changing channel conditions, including performance...

Abstract

A wireless network infrastructure that adapts frame parameters of concurrent interfering receptions in response to the dynamically varying channel conditions. The channel conditions are determined by number of associated wireless end point devices within a cell, their capabilities, anticipated bandwidth usage, QOS (Quality Of Service) demands, priority of service and idle states, cell overlap interferences, near-far interferences and noises. The wireless network infrastructure contains a wireless access point within the cell that assigns a mode to a frame or sub-frame and adapts to channel conditions by varying mode durations and payload lengths. The modes include single transmission mode, plurality of partial concurrent interfering transmission modes and full concurrent interfering transmission mode. These modes allow single as well as concurrent interfering transmissions and receptions of varying payload lengths.

Description

technical field [0001] The invention relates to a wireless communication system, in particular to a wireless access point in a packet switching network. Background technique [0002] Today, wireless access points are widely used because they can provide mobile computing devices with wireless access to the backbone network in wireless local area networks in public and private places. A wireless local area network includes wireless access points that can provide wireless routing services to multiple mobile wireless terminal devices. The most outstanding backbone network is the Internet (Internet), and the other is the intranet (Intranet). Consequently, wireless access points today provide wireless access to the Internet in many public places such as hotels, airports, public buildings and homes. [0003] Examples of terminal wireless devices include personal or laptop computers, servers, set-top boxes, and handheld data / communication devices. Often multiple wireless access p...
