Communications methods and apparatus that facilitate handover decisions and related measurements
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.
