Abstract:
1. A communication unit for use in a wireless communication network in which a transmitting unit is arranged for wireless communication with at least one receiving unit, said network further comprising at least a first relay node of a first multi-hop communication path being arranged to receive a signal from the transmitting unit and forward it to the receiving unit, and a second relay node of a second multi-hop communication path being arranged to receive a signal from the transmitting unit and forward it to the receiving unit, said communication unit comprising a hardware processor and a transceiver, said communication unit configured to: identify at least a first communication path and a second communication path, respectively between the transmitting unit and the receiving unit; calculate, by the hardware processor, at least a first capacity of the first communication path and a second capacity of the second communication path, respectively, said first capacity and second capacity representing long-term capacities of the first and second communication paths respectively, said long term capacities calculated based on a mean value and a variance of channel statistics and a number of transmitting antennas; and communicate, by the transceiver, information related to the capacities of the communications paths to at least one other communication unit in the network provided for comparing the first and second capacities and selecting a relaying scheme between relaying schemes based on the first and second capacities, at least one of the relaying schemes involving cooperative relaying between said first and second relay node.
