Method and apparatus to dynamically select UE processing capabilities based on channel impulse response estimates
Abstract:
A method, an apparatus, and a computer program product for wireless communication are provided in connection with dynamic selection of a UE receiver. In one example, a communications device is equipped to obtain one or more channel impulse response (CIR) estimates, generate a delay spread metric value that characterizes a multipath delay spread of a channel based on the obtained one or more CIR estimates, and select a receiver option with a first power consumption value, for use by the UE, from a plurality receiver options with different optimal power consumption values, based on the generated delay spread metric value. In an aspect, a comparatively more complex receiver option may be selected when the channel is rich in multipath. In another aspect, a comparatively less complex receiver option may be selected when the channel exhibits flat fading.
