Abstract

The present invention discloses systems and methodologies that facilitate coordinating and conducting transmissions to multiple stations in a wireless communication system during a single transmission opportunity. A holder of a transmission opportunity can communicate a request-to-send message or a self-addressed clear-to-send message to one or more stations to establish the transmission opportunity. Subsequently, data transmissions with respective stations can be initiated by transmitting request-to-send messages to the respective stations. At each receiving station, the source address of a received request-to-send message is compared to the address of the holder of the transmission opportunity. If the addresses match for a given request-to-send message, the receiving station transmits aclear-to-send message to the holder of the transmission opportunity in response to the request-to-send message.

Description

[0001] cross reference [0002] This application claims priority to US Provisional Patent Application No. 60 / 866,038, filed November 15, 2006, entitled "TRANSMIAAIONS TO MULTIPLE STATIONS INWIRELESS COMMUNICATION SYSTEMS," which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates generally to wireless communications, and more particularly to techniques for initiating and performing transmissions to multiple devices in a wireless communications system. Background technique [0004] Wireless communication systems, such as wireless local area networks (WLANs), are widely deployed to provide various communication services; for example, voice, video, packet data, broadcast and messaging services can be provided via such wireless communication systems. These systems may be multiple-access systems capable of supporting communication with multiple terminals by sharing the available system resources. Examples of such multiple-...
