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.

First claim

What is claimed is:

1. A method of communications, comprising:
obtaining, by a user equipment (UE), one or more channel impulse response (CIR) estimates;
generating a delay spread metric value that characterizes a multipath delay spread of a channel based on the obtained one or more (CIR) estimates;
ordering a plurality of receiver options with different optimal power consumption values in increasing order of performance that is based on a signal-to-noise ratio (SNR) at an out…
