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.

Abstract: In response to a request from a source cell, a target cell allocates resources for a user equipment (UE) to establish a connection with that target cell. The target cell sends to the source cell a) a set of RRC parameters that identify the allocated resources and b) an indication of a validity time the set of RRC parameters are valid for establishing the connection. The source cell sends the UE an autonomous user equipment mobility (AUM) configuration (including the set of RRC parameters) and an indication of a validity time during which the AUM configuration remains valid for establishing the connection with the target cell associated with that AUM configuration. The UE stores the AUM configuration and the validity time in its local memory, and utilizes the AUM configuration to establish a connection with the target cell only if the validity time is not expired.
