Dynamic configuration of dmrs

A method for wireless communication by a user equipment (UE), comprising:

• transmitting one or more uplink signals to a base station (BS);
• receiving, from the B S, information indicating an allocation of reference signal (RS) resources for the UE, wherein the allocation of the RS resources is based, at least in part, on a Doppler shift associated with the one or more uplink signals;
• and
• at least one of transmitting or receiving one or more RSs based on the allocation of the RS resources.

An apparatus for wireless communication by a base station (BS), comprising:

• at least one processor configured to:
• receive one or more uplink signals from at least one user equipment (UP;
• estimate a Doppler shift associated with the one or more uplink signals;
• determine 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;
• and
• transmit 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;
• and
• a memory coupled with the at least one processor.
