  • Patent number: 8634842
    Abstract: 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.
