20090109892 | HARQ SUPPORTED CLIENT RELAY PROTOCOL - Briefly, in accordance with one or more embodiments, in a HARQ supported client relaying wireless network, if the intended client subscriber station is able to decode the transmission from the base station, an allocated data zone otherwise allocated for relay transmission and acknowledgment zones in the uplink subframe can be used by another client station for uplink transmission. If the intended client subscriber station cannot decode the transmission from the base station but the relay station can, the relay station may use the allocated data zone in the uplink subframe in which to transmit a relay transmission, along with acknowledgment transmissions in the acknowledgment zones. If the relay station also cannot decode the base station transmission, the other client station may use the allocated data otherwise allocated for relay transmission and acknowledgment zones for uplink transmission. | 04-30-2009 |

20090245159 | System and method for node-clustering and multi-hop routing in wideband wireless ad-hoc networks - An ad-hoc network system for computing a proposed number of node-clusters that enable a relative threshold data rate. The ad-hoc network system includes a source terminal, a destination terminal, a plurality of relay terminals, and a cluster determination engine. The source terminal sends a network communication to a destination terminal via a plurality of relay terminals. The cluster determination engine computes a threshold data rate, C, for a number of hops, N, based on a transmission power constraint. The cluster determination engine determines a proposed route for the wireless communication from the source terminal to the destination terminal according to the threshold data rate, C. | 10-01-2009 |
20090247086 | Reducing co-channel interference - A base station may transmit at varied power levels. Subscriber stations receiving the power levels can transmit noise information back to the base station. As a result, co-channel interference can be determined from the varied power transmissions, either in the base station or in the subscriber station. In addition, in some embodiments, the transmissions may include different phases so that the phase of the co-channel interference may be determined as well. | 10-01-2009 |
20090262678 | COOPERATIVE COMMUNICATIONS TECHNIQUES - Techniques are disclosed involving communications between source and destination devices. Such communications may involve multiple cooperating devices that retransmit (e.g., simultaneously retransmit) transmissions sent by a source device. Thus, the delivery of transmissions from source devices to destination devices may involve two or more “hops” (e.g., a first “hop” comprising an initial transmission, and a second “hop” comprising two or more relay transmissions). | 10-22-2009 |
20100008331 | BANDWIDTH ALLOCATION BASE STATION AND METHOD FOR ALLOCATING UPLINK BANDWIDTH USING SDMA - Embodiments of a base station and methods for allocating uplink bandwidth using SDMA are generally described herein. In some embodiments, uplink bandwidth request messages are received on a bandwidth request contention channel from one or more subscriber stations. The uplink bandwidth request messages are generated by the subscriber stations by modulating pilot subcarriers of a randomly selected disjoint pilot pattern with a randomly selected orthogonal sequence. The base station allocates uplink bandwidth to the subscriber stations when the uplink bandwidth request messages are successfully detected and decoded. The base station uses an SDMA technique to determine channel responses based on the orthogonal sequences to detect and decode the uplink bandwidth request messages. | 01-14-2010 |
