Claim 0:
1. A method for wireless communication by a base station (BS), comprising:
receiving one or more uplink signals from at least one user equipment (UE);
estimating a Doppler shift associated with the one or more uplink signals;
determining a density of reference signals (RSs) within a slot for the at least one UE based, at least in part, on the estimated Doppler shift associated with the one or more uplink signals, wherein, based on one or more Doppler shift thresholds, the density of the RSs is different for different carrier frequencies of the one or more uplink signals; and
transmitting information to the at least one UE indicating an allocation of RS resources for the UE, wherein the allocation of the RS resources is based on the density of the RSs for the at least one UE.
