1. A method for wireless communication at a user equipment (UE), comprising:
estimating a first Doppler shift associated with a first transmission reception point and a second Doppler shift associated with a second transmission reception point;
receiving a Doppler pre-compensation indication that indicates that one or more of a first communication from the first transmission reception point or a second communication from the second transmission reception point is Doppler pre-compensated based at least in part on the first Doppler shift or the second Doppler shift;
selecting, based at least in part on the Doppler pre-compensation indication, a first transmission configuration indicator state for the first communication and a second transmission configuration indicator state for the second communication; and
receiving the first communication based at least in part on the first transmission configuration indicator state and the second communication based at least in part on the second transmission configuration indicator state.
