1. A method for wireless communication at a user equipment (UE), comprising:
transmitting one or more messages indicating a capability of the UE to support reception of demodulation reference signals and time drift reference signals according to one or more signaling patterns;
receiving, based at least in part on the capability of the UE, one or more control messages indicating a first signaling pattern for one or more demodulation reference signals via a set of transmission time intervals, the first signaling pattern corresponding to a first allocation periodicity for the one or more demodulation reference signals, and indicating a second signaling pattern for one or more time drift reference signals via the set of transmission time intervals, the second signaling pattern corresponding to a second allocation periodicity for the one or more time drift reference signals that is associated with the first allocation periodicity, wherein the first signaling pattern corresponds to the second signaling pattern; and
receiving a downlink shared channel, the one or more demodulation reference signals, and the time drift reference signals via the set of transmission time intervals, the downlink shared channel multiplexed with the one or more demodulation reference signals according to the first signaling pattern and multiplexed with the one or more time drift reference signals according to the second signaling pattern.
