User equipment (UE) in a cellular communication system is capable of both high data rate uses such as streaming video and low data rate uses such as voice. UE in accordance with the disclosure camps on to a cell with a narrow bandwidth downlink when its data rate requirements are low, rather than a cell with a wide bandwidth download. Since the computational burden of processing the narrow bandwidth downlink signals is less than that for processing the wide bandwidth downlink signals, a power reduction in the UE is realized from the reduced computational load. A normal handover between cells with wide and narrow bandwidth downlinks can be used. Alternatively, a single cell can dynamically change its downlink bandwidth resulting in a reduced computational load and reduced power consumption in the UE.
