Claim:
1. A method, comprising: commanding each of a first user equipment (UE) and a second UE to perform a channel measurement, wherein the first UE and the second UE are in a cell of an enhanced Node B (eNB); determining, based on the channel measurements, a first plurality of spectrum efficiencies associated with a direct communication mode and a second plurality of spectrum efficiencies associated with a second communication mode; determining, based on the first plurality of spectrum efficiencies, a first cost of the direct communication mode; determining, based on the second plurality of spectrum efficiencies, a second cost of the second communication mode; comparing the first cost of the direct communication mode with the second cost of the second communication mode; selecting the direct communication mode for a communication between the first UE and the second UE in response to determining that the first cost is smaller than the second cost; and providing information to facilitate direct communication between the first UE and the second UE to the first UE and the second UE.
