Abstract

Broadcast and multicast (BM) systems have not been reliable in the wireless local area networks. Higher bandwidth and more reliable BM transmissions are necessitated by video and audio applications. A class of BM reliable frames is transmitted at a higher rate. The access point performs some rudimentary collision avoidance to enhance reliability, and individual stations are given the ability to send feedback to the access point regarding the quality of the transmission.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]Under 35 U.S.C. 119, this application claims priority to, and the benefit of; U.S. Provisional Patent Application entitled, “Reliable Broadcast / Multicast (RBM),” having Ser. No. 60 / 906,331, filed on Mar. 12, 2007, which is incorporated by reference in its entirety.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present disclosure generally relates to wireless communications and more particularly relates to systems and methods for improving the reliability of multicast / broadcast traffic from an access point.[0004]2. Background Information[0005]Among other things, FIG. 1 illustrates a typical network configuration for communicating data between stations via an access point in a wireless local area network (WLAN) or 802.11-based network. As illustrated in the non-limiting example of FIG. 1, a network 140 may be coupled to access point 130. In some embodiments, the network 140 may be the Internet, for example. Access point ...
