SOFT-WINDOWING CHANNEL ESTIMATION
First Claim
Patent Images
1. A method for wireless communications by a user equipment (UE), comprising:
- determining, based on a cyclic prefix (CP) length of a channel, a timing window for sampling reference signals transmitted on the channel;
determining a set of weights to apply to samples obtained within the determined timing window, wherein each weight corresponds to a sample obtained within the determined window; and
estimating the channel by applying the weights to the corresponding samples.

Abstract
Certain aspects of the present disclosure relate to techniques for estimating a channel using soft-windowing. A user equipment (UE) may determine, based on a cyclic prefix (CP) length of a channel, a timing window for sampling reference signals transmitted on the channel, determine a set of weights to apply to samples obtained within the determined timing window, wherein each weight corresponds to a sample obtained within the determined window, and estimate the channel by applying the weights to the samples.
