Abstract: Methods and apparatus that facilitate handover related measurements and decision making in a communications system including user equipment (UE) devices, a macro base station and femto base stations (femtocells) are described. In some embodiments a UE device transmits pilots along with identification information using UE device selected transmission resources from a set of recurring UE pilot transmission resources dedicated by a macro base station for UE pilot signal and related device information transmission purposes. Femto base stations measure the UE transmitted pilot signals and report the signal strength measurement results and corresponding device identifiers to a handoff decision control entity, e.g., an eNodeB or control node, which makes handover decisions. By relying on UE transmitted pilots measured by multiple base stations, e.g., femto base stations, the need for femto cells to transmit pilots can be reduced while well informed UE handoff decisions still being possible.

Abstract: Methods, systems, and devices are described that provide for D2D synchronization. The methods, systems, and/or devices may include tools and techniques that provide for synchronizing a mobile device based on detection of a reliability alarm. A reliability alarm may be used between mobile devices, which is transmitted and/or received on specific D2D resources. Since the resources are reserved for the reliability alarm, a mobile device which was previously isolated from network synchronization will be able to receive the reliability alarm that a reliable synchronization signal is close when it moves within range of a reliable device. Once a reliability alarm is received the mobile device may free other resources to allow it to receive synchronization signals from the reliable devices. The mobile device may then synchronize with the network based on the received synchronization signals and transmit its own reliability alarm for subsequent isolated devices to use.

Abstract: Methods and apparatus for controlling interference with regard to important control signals, e.g., synchronization signals and broadcast channel signals, are described. A configurable base station monitors for and receives signals from other base stations in its local vicinity and determines the implemented frame timings corresponding to the other deployed base stations. If possible, the configurable base station selects to use a frame timing offset which is different from the frame timing offsets being used by the other base stations. In some embodiments, symbol level and subframe level synchronization are maintained between the base stations; however, frame level synchronization may, and sometimes does vary. Different adjacent base stations may, and sometimes do, intentionally offset their frame boundaries by multiples of a subframe.
