20080212460 | ROBUST TRANSMISSION SCHEME FOR WIRELESS NETWORKS - Systems and methods are described that facilitate assigning a predefined manner in which interfering transmissions may be fully or partially orthogonalized, as well as transmission time periods during which the orthogonalization protocol(s) may be employed. Depending on interference conditions, flexible resource reuse may be implemented to mitigate interference without unduly taxing resources. The subject of the innovation may be employed in, for instance, an ad hoc or unplanned/semi-planned wireless communication environment. | 09-04-2008 |
20090022173 | CONTROL INDICATIONS FOR SLOTTED WIRELESS COMMUNICATION - Multiple control indications are transmitted within timeslots defined for a slotted communication system. For example, a wireless node may transmit a control indication at a beginning of a timeslot and at an end of a timeslot. A control indication may comprise a resource utilization message that a node generates in an attempt reduce inference at the node that is caused by transmissions by neighboring nodes. A node also may synchronize to a received timeslot of another node based on the position of one or more control indications within the timeslot. Here, each control indication may include information that indicates the position of the control indication within the timeslot. | 01-22-2009 |
20090034458 | METHOD FOR SCHEDULING ORTHOGONALLY OVER MULTIPLE HOPS - Apparatus and method for providing a relay between uplink and downlink nodes. The relay is provided by simultaneously communicating with the uplink and downlink nodes on a common channel. | 02-05-2009 |
20090036138 | METHOD FOR SCHEDULING ORTHOGONALLY OVER MULTIPLE HOPS - Apparatus and method for supporting wireless downlink and uplink connections. In the downlink direction, an apparatus receives from the downlink node a request to communicate using an allocation of radio resources specified by the downlink node, and transmits to the downlink node a grant to communicate using at least a portion of the specified allocation of radio resources. In the uplink direction, the apparatus sends a request to a downlink node to communicate using a specified allocation of radio resources, and receives from the downlink node a grant to communicate using at least a portion of the specified allocation of radio resources | 02-05-2009 |
20090067369 | ROUTING IN A MESH NETWORK - Apparatus and method for associating with any one of a plurality of access points in a mesh network including estimating a plurality of metrics for the access points, the estimated metrics being related to throughputs provided by the access points, and selecting one of the access points to associate with based on the metrics and a plurality of backhaul metrics for the access points, the backhaul metrics being related to backhaul throughputs for the access points. The backhaul metrics may be advertised by the access points. | 03-12-2009 |
20110045776 | METHOD AND APPARATUS FOR DETECTING OFDM SIGNALS IN THE PRESENCE OF FREQUENCY ORTHOGONAL OFDM INTERFERERS - Certain aspects of the present disclosure relate to techniques and apparatus for detecting Orthogonal Frequency Division Multiplexing (OFDM) signals in the presence of frequency orthogonal OFDM interferers. | 02-24-2011 |
20120294258 | UTILITY MAXIMIZATION SCHEDULER FOR BROADBAND WIRELESS COMMUNICATION SYSTEMS - Certain aspects of the present disclosure relate to a technique of designing a Media Access Control (MAC) scheduler for uplink communication in high rate wireless data systems, such as Long Term Evolution (LTE) wireless communication systems. | 11-22-2012 |
20150215959 | DETERMINING A TRANSMIT PARAMETER FOR WIRELESS COMMUNICATION - A wireless media access control supports asynchronous communication and overlapping transmissions. Here, a wireless node may determine whether to request or schedule a transmission based on control messages it receives from neighboring nodes. In some implementations a scheduled transmission may be divided up into several segments so that a transmitting node may receive and transmit control messages between segments. In some implementations a monitoring period is defined after a scheduled transmission period to enable the transmitting node to acquire control information that may otherwise have been transmitted during the scheduled transmission period. In some implementations data and control information are transmitted over different frequency division multiplexed channels to enable concurrent transmission of the data and control information. | 07-30-2015 |
