MAC DATA SERVICE ENHANCEMENTS |
摘要 |
Wireless video transmissions over a MAC layer employ various techniques to improve throughput which may negatively impact latency, such as Block-ACK and data aggregation. To improve latency while continuing to improve throughput, data packets are fenced according to application layer specifications and then transmitted. For video data, Block-ACK sequences and aggregation sequences are terminated at the end of video frames or video slices. For data aggregation, a physical layer data packet concludes at the end of a video frame or slice. The application layer can indicate to the MAC layer when such packet fencing is to occur. In use with 802.11n transmission a data flag may be used by the MAC layer to facilitate fencing. |
