Average environmental channel estimation

An apparatus for wireless communications at a user equipment (UE), comprising:

• a processor,
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive, over a time period, a plurality of signals at the UE;
• estimate a Doppler spread for each subset of a plurality of subsets of the time period based at least in part on a first measurement of the plurality of signals;
• estimate, for each of the plurality of subsets of the time period, a power delay profile comprising an estimate of received powers over a corresponding subset of the time period based at least in part on a second measurement of the plurality of signals;
• combine the Doppler spreads over the time period and the power delay profiles over the time period;
• and
• determine one or more communication parameters based at least in part on the combined Doppler spreads and the combined power delay profiles.
