DYNAMIC CCA FOR INCREASING SYSTEM THROUGHPUT OF A WLAN NETWORK

摘要

The present invention relates generally to wireless networking, and more particularly to methods and apparatuses for providing increased system throughput of next generation WLAN devices without impacting the throughput of legacy devices. According to certain aspects of the invention, some embodiments allow a controller to set the energy level for an STA to use to determine whether the medium is busy or not. According to certain other aspects of the invention, some embodiments allow an STA to set the energy level individually of the controller but considering the received energy levels from neighbor AP's in the network. According to further other aspects of the invention, some embodiments allow an STA to set the energy level individually by taking into consideration of the load and percentage of legacy devices in the BSS and OBSSs of the network.

主权项

1. A method for increasing throughput of wireless devices and systems in a WLAN network including legacy wireless devices, comprising:
receiving, at a wireless device in the WLAN, Clear Channel Assessment (CCA) threshold related information from an associated Access Point (AP), wherein the associated AP is an AP with which the wireless device is associated; receiving, at the wireless device, CCA threshold related information from a neighbor AP, wherein the neighbor AP is an AP with which the wireless is not associated; setting the CCA threshold of the wireless device based on the received CCA threshold information from both the associated AP and the neighbor AP.
