Abstract

A method of operating a node of a communications network comprises the node requesting a user equipment unit to prepare a measurement report concerning a measurement object. The measurement report includes (a) a measurement result for the measurement object as measured from a current serving cell and a measurement result for the measurement object as measured from a neighbor cell; and (b) additional measurement reporting including measurements that are available at the user equipment unit from multiple serving carriers. The method further comprises the node configuring the user equipment unit to ensure that the user equipment unit includes a reference signal received power (RSRP) value for the measurement result for the measurement object as measured from the neighbor cell.
