Claim Text:
1. A method, comprising: obtaining a downlink power control value including determining a maximum downlink transmitting power which device-to-device (D2D) user equipment (UE) may use on at least one cellular shared downlink resource; obtaining an uplink power control value including determining a maximum uplink transmitting power which device-to-device (D2D) user equipment (UE) may use on at least one cellular shared uplink resource; measuring a first link quality for reusing the at least one cellular shared downlink resource based at least in part on the downlink power control value; measuring a second link quality for reusing the at least one cellular shared uplink resource based at least in part on the uplink power control value; and determining a suitable device-to-device (D2D) mode for a first one of the device-to-device (D2D) user equipment (UE) to establish a first device-to-device (D2D) connection based at least in part on the first link quality, the second link quality, the downlink power control value and the uplink power control value; wherein determining the suitable D2D mode comprises selecting from among at least one dedicated mode and at least one shared mode, and each cellular shared downlink resource and each cellular shared uplink resource is a resource that may be shared among at least two D2D UEs and at least one cellular UE.
