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.

摘要： The embodiments of the present invention relate to methods and apparatuses (600, 700) for coordinating interference in a telecommunications LTE based system. According to exemplary embodiments, an apparatus acting as a macro radio base station (eNB) (600) is configured to decide on what radio resources to schedule to its UEs and further decide on what resources to leave unutilized. Information on the decided resources is further transmitted in an interference coordinate signalling message, to at least one relay node (RN) (700) via at least one layer (1) control channel. The interference coordination signalling message will assist the RN (700) to make its own scheduling decision based on the information in the signalling message.
