Method for efficient utilization of radio resources for transmission of video streams in wireless communications system

摘要

The invention provides a wireless communications system. In one embodiment, the wireless communications system comprises a coordinating communications device, a source communications device, and a sink communications device. The coordinating communications device transmits a predetermined bits sequence at the beginning of a radio frame at a rate of a first fixed interval. The source communications device receives frames of a streaming session, detects a duration and first starting time of a frame, and wherein forwards information about the duration and the first starting time of one or more of the frames to the coordinating communications device. The coordinating communications device then determines the duration of a second fixed interval and second starting time in accordance with a predetermined rule based on the information received from the source communications device. The coordinating communications device then transmits the predetermined bits sequence at the second starting time of a radio frame at a rate of the second fixed interval, and the source communications device forwards the frames to a sink communications device.
