Communications methods and apparatus for allocation of resources and handover related measurements
Methods and apparatus for allocation of resources for handover related measurements in a communications system including user equipment (UE) devices, a macro base station and small base stations (e.g., femtocells) are described. Some embodiments are well suited for systems where the number of femtocells may equal or outnumber the number of UE devices. In some embodiments a macro base station allocates periodic communications resources for transmission of pilots by UEs or femtocells. The macro base station configures either femtocells or active UEs to transmit pilots using the allocated communications resources based on the relative number of femtocells to active UEs in the coverage area of the macro base station, devices which are lower in number transmitting the pilots. Transmitters (UE devices or femtocells) transmit pilots along with identification information using the allocated resource(s) and receivers measure the pilot signals. The pilot signal measurements may be used to make handover decisions.
