Controlling a reference signal pattern based on doppler parameters

A base station for wireless communication, comprising:

• at least one processor;
• a transceiver communicatively coupled to the at least one processor;
• and
• a memory communicatively coupled to the at least one processor,
• wherein the at least one processor is configured to:
• transmit first control information indicating an initial demodulation reference signal (DMRS) pattern;
• communicate with a user equipment (UE) utilizing a carrier configured according to the initial DMRS pattern;
• transmit second control information indicating a subsequent DMRS pattern that is selected based on whether one or more Doppler parameters corresponding to the carrier exceed a high Doppler threshold, the subsequent DMRS pattern being different than the initial DMRS pattern;
• and
• communicate with the UE utilizing the carrier configured according to the subsequent DMRS pattern.

A method of wireless communication operable at a user equipment (UE), the method comprising:

• receiving first control information indicating an initial demodulation reference signal (DMRS) pattern;
• communicating with a base station utilizing a carrier configured according to the initial DMRS pattern;
• receiving second control information indicating a subsequent DMRS pattern that is selected based on whether one or more Doppler parameters corresponding to the carrier exceed a high Doppler threshold, the subsequent DMRS pattern being different than the initial DMRS pattern;
• and
• communicating with the base station utilizing the carrier configured according to the subsequent DMRS pattern.
