摘要： A backhaul link is established between a base station and a relay that assists the base station in communicating with a mobile device over an access link established between the relay and the mobile device. The channel response of the backhaul link is determined by estimating first and second parts of the backhaul link channel response, the second part changing faster than the first part. The first part of the backhaul link channel response is estimated by calculating an average of the backhaul link channel response over a predetermined period at the relay and the second part is estimated by calculating variation in the backhaul link channel response over the predetermined period at the relay. Quantized versions of the first and second parts of the backhaul link channel response are transmitted from the relay to the base station over the backhaul link.

摘要： A method of allocating radio resources to communication links of a wireless communication system based on status parameters of each of the links, the communication system having a plurality of network nodes, a plurality of relays associated with the network nodes, and a terminal accessing the communication system. A first radio resource allocation may be determined by balancing the performance of a relay-to-network-node communication link of each relay against the performance of a corresponding terminal-to-relay communication link. A second allocation may be determined by balancing the performance of the relay-to-network-node communication link of each relay against the performance of a terminal-to-network-node communication link. A final allocation may be determined by calculating a weighted average value of the first and second allocations.
