摘要： International Mobile Telecommunications (IMT) Advanced technology, also known as 4th Generation (4G) targets to support up to 100 MHz BW. LTE currently supports single carrier bandwidths of up to 20 MHz. The present application describes a multi-carrier approach in which some embodiments of the invention provide a simple solution of aggregating multiple single carrier bandwidths to obtain a wider bandwidth (>20 MHz). Such an approach may extend Long Term Evolution (LTE) bandwidth to greater than that provided by a single carrier, yet maintain full backward compatibility with technologies that predate 4G technology and utilize smaller, single carrier bandwidths. More generally, embodiments of the invention can apply to other communication standards than only LTE.

摘要： A method selects a path for forwarding a data packet in a wireless communication system. A system capacity versus delay impact curve is calculated for a direct path to mobile station. The direct path has a capacity cost based on communication quality of a direct link between a base station and the mobile station. This curve is shifted by a predetermined time corresponding to an additional delay over a relay path to produce a projected capacity curve for the relay path having a second capacity cost determined according to a combined measure of signal quality of multiple links in the relay path. The second capacity cost is multiplied by a capacity cost ratio to produce a relay capacity curve. The direct path or the relay path is selected based on a comparison of the system capacity versus delay impact curve and the relay capacity curve according to a QoS requirement.

摘要： Systems and methods for providing distributed Automatic Repeat Request (ARQ) in a wireless communication system are described herein. In one embodiment, a relay station interconnects a base station of the wireless communication system and one or more mobile stations. A first ARQ process is performed for a first connection between the base station and the relay station. A separate second ARQ process is performed for a second connection between the relay station and a mobile station. In this manner, rather than having end-to-end ARQ between the base station and the mobile station, a distributed ARQ process is provided.

摘要： Systems and methods of performing power control in combination with AMC are provided. AMC is performed on the basis of an AMC parameter such as CINR. Once the AMC is set to a highest available AMC for transmission to a given receiver, if the CINR indicates that the highest AMC could be transmitted with less transmit power, the power is reduced. For receivers that are not receiving the highest available AMC for that receiver, they may have their transmit power increased.
