Abstract
The embodiments relate to a wireless communications apparatus configured to operate as one of a source node, a relay node or a destination node in a network comprising a plurality of source nodes, relay nodes and destination nodes configured to support dual-hop communication using one of said relay nodes to intercede between one of said source nodes and one of said destination nodes, and a method for selecting a relay node. The wireless apparatus is configured to collect channel characteristics between the intended source node and each relay node, and between each relay node and the intended destination node, and select a relay node for relaying a signal emitted by the intended source node by determining a mode of operation for performing the selection on the basis of collected channel characteristics. The wireless communication apparatus is further configured to change the mode of operation to a different one if the channel characteristics change. The mode of operation of performing the relay node selection is one of a first mode and a second mode. In the first mode; the relay node is selected on the basis of said channel characteristics between the intended source node and each relay node and in the second mode; the relay is selected on the basis of said channel characteristics between each relay node and the intended destination node.
