摘要： Time synchronization in a wireless communication system comprises transmitting a synchronization frame from a transmitter to a receiver over a wireless communication medium. The synchronization frame includes a timestamp indicating the transmitter local time when a symbol at a predefined position of the synchronization frame is placed on the wireless communication medium for transmission. The synchronization frame is received at the receiver which determines a receiving time comprising the receiver local time when said symbol of the synchronization frame was received at the physical layer of the receiver. Time synchronizing is performed by determining a difference between said timestamp and said receiving time, and adjusting the receiver local time based on said difference to time synchronize the receiver with the transmitter.

摘要： A method and system for data communication in a wireless network is provided. A wireless transmitter transmits a locality check message from a wireless transmitter to a wireless receiver over a wireless communication medium. Upon receiving a locality check response message from the wireless receiver, the wireless transmitter marks the locality check response message as valid even if it arrives after an original locality check time period since transmission of the locality check message, but before the end of an adjusted locality check time period. The adjusted locality check time period comprises said original locality check time period adjusted by delays in processing layers at the transmitter and wireless communication medium access delays in data communication between the wireless transmitter and the wireless receiver.

摘要： A method and system for transmission of video information is provided. A transmitting wireless station performs chroma partitioning of pixels in a video frame into different partitions. The chroma partitioning includes separating luminance (Y) information from chrominance information (CB and CR) of each pixel in a set of spatially correlated pixels. The luminance (Y) information are placed into different partitions. The different partitions into different packets and transmitted over a wireless communication medium to a receiving wireless station. The video information is selectively adapted to a lower data transmission rate with reduced quality degradation by dropping less important partitions.
