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： Communication of stereoscopic three dimensional (3D) video information. One embodiment comprises wireless communication of stereoscopic 3D video information including an uncompressed first eye view video frame and a corresponding stereoscopic uncompressed second eye view video frame, from a transmitting wireless station to a receiving wireless station. In one embodiment, a set of pixels in an uncompressed first eye view video frame is transmitted over a wireless communication medium. Pixel information in a set of pixels in an uncompressed second eye view video frame corresponding to the first eye view set of pixels is reduced to generate a reduced set of pixels. The reduced set of pixels is transmitted over the wireless communication medium. At the receiving wireless station, an uncompressed second eye view video set of pixels is reconstructed based on said first eye view set of pixels and said reduced set of pixels.

摘要： A method and system for wireless data communication for peer wireless stations in a network is provided. A pair of peer wireless stations perform discovery on a predefined wireless communication channel to discover each other. Upon peer wireless stations successfully discovering one another, a wireless communication channel is selected to setup a connection between the peer wireless stations for data communication on the selected wireless communication channel. The peer wireless stations then perform connection setup and data communication over the selected wireless channel. In one implementation, the network comprises a wireless local area network (WLAN) for ad-hoc Independent Basic Service Set (IBSS) peer-to-peer communication. Further, the peer wireless stations conduct millimeter wave (mmWave) directional data transmissions between the peer wireless stations on the selected wireless data communication channel.

摘要： A system and method for efficiently communicating messages over a low-rate channel between multiple devices in a system for wireless communication of uncompressed video is disclosed. The method includes various control bits in a beacon control field of a beacon frame to improve the efficiency of the beacon processing, thereby reducing beacon processing time and size of the beacon frame itself. The transmitting device can use one or more of the various control bits to indicate whether there are changes in various MAC payload information fields. The receiving station can use one or more of the control bits to eliminate the need to parse one or more MAC payload information fields whose values have not changed from the previous beacon frame.
