Abstract  Abstract

Methods, systems, and devices for wireless communications are described in which user equipment (UE) may provide a capability indication to one or multiple transmission reception points (TRPs) that indicates whether the UE is capable of performing Doppler pre-compensation. One or more of the TRPs may transmit configuration information to the UE to configure Doppler pre-compensation for subsequent communications. The UE may indicate that multiple Doppler shifts for a single communication with multiple TRPs is supported, or that a single Doppler shift or no Doppler shift is supported. The UE, when Doppler pre-compensation is supported and configured, may estimate one or more Doppler metrics (e.g., a Doppler shift, a maximum Doppler spread, or both) for one or multiple TRPs based on one or more reference signals from the TRPs, and may transmit one or more uplink communications based on the estimated Doppler metrics.
