20080218413 | MILLIMETER-WAVE COMMUNICATION STATIONS WITH DIRECTIONAL ANTENNAS AND METHODS FOR FAST LINK RECOVERY - 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. | 09-11-2008 |
20090232116 | MECHANISM TO AVOID INTERFERENCE AND IMPROVE CHANNEL EFFICIENCY IN MMWAVE WPANS - 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. | 09-17-2009 |
20090233554 | Mitigation of internetwork interference - 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. | 09-17-2009 |
20090233635 | Discovering neighbors in wireless personal area networks - A neighbor discovery protocol enables a network coordinator to provide time periods during which different classes of devices produce training sequences. The coordinator can transmit information about these time periods in a plurality of different directions so that in-range devices with directional antenna systems receive the communication. The coordinator can also compile interference reports during the neighbor discovery period and thereafter. These reports may be useful in determining whether or not spatial reuse is appropriate between two particular nodes in a given link, in a particular direction. | 09-17-2009 |
20100157952 | Dynamic CTA adjustment across superframes in a wireless network - In a wireless communications network, various embodiments of the invention provide a technique for requesting an extension or truncation of the previously assigned channel time allocation (CTA), and extending that extension or truncation across multiple superframes without having to make further requests. The request may be made by transmitting an Information Element (IE) that indicates how many superframes the request applies to. | 06-24-2010 |
20100321402 | DISPLAY UPDATE FOR A WIRELESS DISPLAY DEVICE - Embodiments of partial update for a wireless display device include providing an update information message identifying a location of the partial update and the changed image data. A display source identifies changes in image data stored in a frame buffer, generates an update information message to identify the location of the changed image data and to provide the changed image data. A display sink receives the update information message and merges the changed image data with image data stored in a local frame buffer. | 12-23-2010 |

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. | 01-17-2013 |
20130179929 | WIRELESS VIDEO CLOCK SYNCHRONIZATION TO ENABLE POWER SAVING - In a wireless video system, the clock rate for wirelessly transmitting the video data from the transmitting device should be identical to the clock rate for receiving the video data at the receiving device. But the two devices have separate clocks, whose frequencies may drift apart over time, leading the video buffer to be over run or under run. Clock synchronizing messages to prevent this may be sent at short intervals when clock synchronization is first being acquired, and at larger intervals after clock synchronization has already been achieved and is merely being maintained. | 07-11-2013 |
20130314386 | DISPLAY UPDATE FOR A WIRELESS DISPLAY DEVICE - Embodiments of partial update for a wireless display device include providing an update information message identifying a location of the partial update and the changed image data. A display source identifies changes in image data stored in a frame buffer, generates an update information message to identify the location of the changed image data and to provide the changed image data. A display sink receives the update information message and merges the changed image data with image data stored in a local frame buffer. | 11-28-2013 |
