摘要： A method and system for device discovery in a wireless network is provided. The device discovery involves directionally transmitting a data unit from a transmitting station over a channel in different directions to emulate omni-directional transmission, receiving the data unit transmissions from different directions at a receiving station, determining the quality of the transmissions received from the different directions, and detecting location information for the transmitting station relative to the receiving station based on the highest quality transmission among the transmissions received from the different directions. Further, if a channel has sufficient bandwidth to satisfy direct link communication between two stations, then during a direct link set-up stage, the two stations conduct a probing message exchange using omni-direction transmission, and upon successful probing, obtain communication link status information and set proper communication configurations for the two stations based on the communication link status information.

摘要： A system and method for performing medium access control in a system for wireless communication of uncompressed video is disclosed. In one aspect, the method includes communicating a control initiation request message during a contention based period of a superframe period. The control initiation request message contains information allowing a device coordinator to determine a reserved time slot for communication of the requested message exchange. The requested message exchange is then performed in a non-contentious environment, thereby limiting collisions of contention based messages. The control initiation procedure and subsequent message exchanges take place on a low-rate channel. Transmission on the low-rate channel is time division duplexed with a high-rate channel, where transmission at any one time can take place on either the high-rate or the low-rate channel.

摘要： Wireless communication between a first transmitter and a first receiver for a new transmission is established on the same wireless data channel used for ongoing transmission between a second transmitter and a second receiver. This is achieved by determining if the second receiver can receive signals from the first transmitter, and determining if the first receiver can receive signals from the second transmitter. If the second receiver cannot receive signals from the first transmitter, and the first receiver cannot receive signals from the second transmitter, then a new transmission is performed from the first transmitter to the first receiver by spatial reuse of the wireless data channel at least partially concurrently with the ongoing transmission on the data channel.

摘要： A method of efficient scheduling for portable devices communicating with a coordinator over a network is disclosed. The method includes: listening for beacons broadcasted by a coordinator; assigning, by the coordinator, a single contiguous time block (CTB) for portable devices during a superframe defined by consecutive beacons; scheduling a single wake period of one of the portable devices, which overlaps inclusively with consecutive beacons and the single CTB; and minimizing duration of the single wake period of the portable device. The single CTB may be arranged next to one of the consecutive beacons. The method may further comprise assigning, by the coordinator, a single random access time block (RATB) for the one of the portable devices so as to overlap with the single wake period. The RATB may be arranged next to one of consecutive beacons. The CTB may be arranged next to the RATB. The CTB may be arranged next to one of the consecutive beacons.
