摘要： Briefly, a mechanism to avoid interference and improve channel efficiency in mmWave Wireless Personal Area Networks (WPANs) is disclosed. According to an embodiment of the present invention, neighbor devices can identify whether a certain high rate channel is being used or not through a communication on another channel, and thus avoidance actions may be taken by neighbor devices even if they do not receive signals from the high rate channel.

摘要： When a device in one wireless network receives interfering transmissions from an overlapping neighboring network, the neighboring network may be notified of the interference so that non-interfering schedules can be worked out. In one embodiment, the device receiving the interference may broadcast its own communications schedule. Device(s) in the interfering network may pick up that schedule, and pass it on to their controller, which can rearrange its own network schedule to be non-interfering. In another embodiment, the device receiving the interference may notify its own network controller with the pertinent information, and that controller may contact the controller of the interfering network to coordinate non-interfering schedules.

摘要： Embodiments of millimeter-wave communication stations with directional antennas and methods for fast link recovery are generally described herein. Other embodiments may be described and claimed. In some embodiments, a transmitting station retransmits a packet in an adjacent direction when an acknowledgement is not received from a receiving station after a number of retransmission attempts. In other embodiments, a receiving station changes its reception to an adjacent direction when a packet is not received from a transmitting station after a number of missed reservations.
