A method of improved total radio resource usage in a wireless communication system in which relay user equipments, UEs, are used for communication between remote UEs and a base station, wherein the total radio resource usage refers to links between relay UEs and remote UEs and links between relay UEs and the base station, the method performed at a remote UE comprising: determining a first link quality, the first link quality indicating a link quality of a first link between a first potential relay UE and the remote UE; determining a second link quality, the second link quality indicating a link quality of a second link between the first potential relay UE and a first base station; determining a third link quality, the third link quality indicating a link quality of a third link between a second potential relay UE and the remote UE; determining a fourth link quality, the fourth link quality indicating a link quality of a fourth link between the second potential relay UE and a second base station; weighting each of the first, second, third and fourth link quality, wherein more weight is given to the first link quality than the second link quality and wherein more weight is given to the third link quality than the fourth link quality; ranking the first potential relay UE relative to the second potential relay UE, the ranking of each of the first potential relay UE and the second potential relay UE being based on a combination of the weighted first link quality, the weighted second link quality, the weighted third link quality and the weighted fourth link quality; and selecting one of the first potential relay UE and the second potential relay UE for a relay connection based on the highest ranking of the first potential relay UE and the second potential relay UE. determining a first link quality, the first link quality indicating a link quality of a first link between a first potential relay UE and the remote UE; determining a second link quality, the second link quality indicating a link quality of a second link between the first potential relay UE and a first base station; determining a third link quality, the third link quality indicating a link quality of a third link between a second potential relay UE and the remote UE; determining a fourth link quality, the fourth link quality indicating a link quality of a fourth link between the second potential relay UE and a second base station; weighting each of the first, second, third and fourth link quality, wherein more weight is given to the first link quality than the second link quality and wherein more weight is given to the third link quality than the fourth link quality; ranking the first potential relay UE relative to the second potential relay UE, the ranking of each of the first potential relay UE and the second potential relay UE being based on a combination of the weighted first link quality, the weighted second link quality, the weighted third link quality and the weighted fourth link quality; and selecting one of the first potential relay UE and the second potential relay UE for a relay connection based on the highest ranking of the first potential relay UE and the second potential relay UE.
