METHODS AND APPARATUS TO PROVIDE FAIRNESS FOR WIRELESS LOCAL AREA NETWORKS THAT USE EXTENDED PHYSICAL LAYER PROTECTION MECHANISMS

摘要

Methods and apparatus to provide fairness for wireless local area networks that use extended physical layer (a.k.a. PHY) protection mechanisms are disclosed. A disclosed example method comprises choosing a length field value (530) for a frame header (520) such that, when a transmit operation is ended (544), a legacy wireless station and a non-legacy wireless station of a wireless local area network are able to start contending for a wireless medium at substantially a same instant (555), and sending a frame (522) across the wireless medium that includes the frame header.
