| 20090232063 | Arrangements for association and re-association in a wireless network - A method is disclosed for associating network devices to a network. The method can include receiving a beacon from a source by an antenna array, allocating resources to beamform and beamforming after receiving at least a portion of the beacon. The beamforming can be accomplished prior to completion of an association request and prior to receipt of an acceptance signal in response to the association request. Accordingly directional transmissions can be utilized transmit at least part of an association request and to transmit an acceptance signal corresponding to the association request. | 09-17-2009 |
| 20090232103 | Apparatus and method adapted for directional bandwidth reservation with fixed announcement slot in wireless networks - An embodiment of the present invention provides an apparatus, comprising a transceiver operable in a wireless personal area network, wherein the transceiver is configured to communicate with a coordinator and at least one receiver and wherein the transceiver and the coordinator use a directional reservation of free channel time blocks using contention-based slots, by selecting uniformly at random contention slots by the transceiver and transmitting a bandwidth reservation request message specifying the requested reservation period using directional transmission pointed towards the coordinator. | 09-17-2009 |
| 20090232104 | Techniques enabling dynamic bandwidth reservation in a wireless personal area network - An embodiment of the present invention provides a method, comprising dynamically reserving free channel time blocks for directional transmissions in a wireless personal area network (WPAN) by a transceiver communicating with a Coordinator and the Coordinator allocating a part or a whole of unreserved channel time blocks for a directional link during a handshake with the transceiver. | 09-17-2009 |
| 20090232105 | MECHANISM TO AVOID INTERFERENCE AND IMPROVE COMMUNICATION LATENCY IN MMWAVE WPANS - Briefly, a mechanism to avoid interference and improve channel efficiency in mmWave Wireless Personal Area Networks (WPANs) is disclosed. In particular, interference information during various time periods is tracked and used to optimize transmission scheduling. Further, a mechanism is provided to improve communication latency by distributing responsibility for coordination of slots amongst multiple transmitting devices. | 09-17-2009 |
| 20090233549 | Techniques for MMWAVE WPAN communications with high-directional steerable antennas combining omni-directional transmissions with beamforming training - An embodiment of the present invention provides a method for communicating in a millimeter wave (MMWAVE) wireless personal area network (WPAN) system using a reliable low-rate omni-directional communications mode implemented as TX-RX space scanning using directional antennas; and using a high-rate directional communications mode with beamformed directional antennas. | 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 |
