摘要： A system and method for discovering and tracking communication directions is disclosed herein. In one embodiment, communication directions for two devices with asymmetric antenna systems are discovered. In one embodiment, a contention access period (CAP) is partitioned into an association CAP and a regular CAP, either of which may be further partitioned into sub-CAPs corresponding to different reception directions. In one embodiment, an association request command is transmitted by a device at different association sub-CAPs to train a transmission direction of the device. In one embodiment, further training is performed to find the best communication directions, as collisions may occur when association request commands are transmitted at different association sub-CAPs.

摘要： A system and method of performing a beam discovery between a device and a plurality of other devices in a wireless network is disclosed. Sector training sequences to a plurality of other devices are transmitted via a transmit directional antenna having a set of transmit sectors. A plurality of feedback messages are received from the plurality of other devices, where the plurality of feedback messages are indicative of optimum transmit sectors that have been determined at the other devices based at least in part on the sector training sequences. Beam training sequences are transmitted to the plurality of other devices via the transmit directional antenna. A plurality of feedback message indicative of optimum transmit beam directions within the optimum transmit sectors are received from the plurality of other devices.

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 wireless communication in a TV band white space spectrum is provided. A wireless master device keeps track of available wireless communication channels in a white space spectrum. The master device performs an enablement process for enabling a corresponding client device to transmit on a wireless channel. During the enablement process, the master device allows the client device to select a wireless channel for communication from among: a specific operating wireless channel, a subset of the available wireless channels, and all available wireless channels.
