Abstract: Improved systems and techniques for communication in an environment in which muting of resources is used to avoid interference between cells. If a cell, represented by a macro eNB for example, is muting resources, those resources can be made available, under appropriate conditions, to user devices, such as UEs, engaging in device to device communication. Allocation of muted resources to D2D UEs can be based on meeting of conditions, such as that the D2D UEs be outside of a specified proximity to a cell, such as a small cell, using the resources, or that the D2D UEs transmit at less than a specified power. The UEs may take measurements to determine if the conditions are met and report the measurements to their base stations, which then determine whether to allocate the muted resources and configure the UEs with resource allocation information.
