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.

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.
