Method and apparatus to dynamically select UE processing capabilities based on channel impulse response estimates

An apparatus for communication, comprising:

• means for obtaining, by a user equipment (UE), one or more channel impulse response (CIR) estimates;
• means for generating a delay spread metric value that characterizes a multipath delay spread of a channel based on the obtained one or more CIR estimates;
• means for 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 output of a receiver;
• means for selecting a receiver option with a first power consumption value, for use by the UE, from the plurality of receiver options based on a comparison of the generated delay spread metric value with a set of thresholds related to the plurality of receiver options;
• and
• means for maintaining the UE at the selected receiver option for a number of time slots prior to determining whether to select a different receiver option from a first set of receiver options based on a comparison of the delay spread metric value with a set of thresholds related to the first set of receiver options, wherein the first set of receiver options is limited to receiver options from the plurality of receiver options that are adjacent to the selected receiver option within the order of performance.
