Abstract: A method, an apparatus, and a computer program product for wireless communication are provided for using power control to reduce potential interference to a macro eNB by a UE engaged in D2D communications. An eNB may be operable to generate a fractional power control parameter based on a macro eNB power saturation value and broadcast the factional power control parameter. A UE may be equipped to receive the factional power control parameter and determine whether the fractional power control parameter plus a path loss value between the UE and the macro eNB is less than a maximum power used for the D2D communications. The UE may reduce the maximum transmit power used for D2D communications when the fractional power control parameter plus a path loss value between the UE and the macro eNB is less than a maximum power used for the D2D communications.

Abstract: A wireless communications device supporting peer-to-peer communications acquires peer-to-peer communications resources for an extended period of time. In some embodiments, a base station assigns the resources to the device, while in other embodiments, the device reserves, e.g., self-assigns peer-to-peer communications resources for an extended period of time. The wireless communications device decides that it will not be using an acquired peer-to-peer communications resources, e.g., a particular acquired peer-to-peer traffic segment. The wireless communications device transmits a resource availability indicator indicating that it will not be using the particular peer-to-peer communications resource. Another wireless communications device, which detects the resource availability indicator, may use the peer-to-peer communications resource which is not be used by the device to which it is assigned.

Abstract: A method, an apparatus, and a computer program product for supporting RLC layer handover between WAN supported D2D communications and direct D2D communications. In one example, a first UE may be operable to transmit a WAN handover request including a peer identifier and a cell identifier associated with a second UE to an eNB, where the first UE and the second UE are engaged in direct D2D communications. The eNB may be equipped to communicate the WAN handover request to a second eNB associated with the second UE and receive a RLC parameter indicating a last successful reception by the second UE. The eNB may transmit the RLC parameter to the first UE. The first UE may be equipped to determine a subsequent content item based on the received RLC parameter and may transmit the subsequent content item to the second UE via the eNB.

The first UE may determine a subset of resources to use for D2D communications with a second UE based on one or more D2D resource determination schemes, and may signal the determined subset to the first eNB. The first eNB may receive the subset of resources and transmit a control signal indicating that the subset of resources has been allocated for D2D communications.
