1. A user equipment (UE) for wireless communication, comprising:
one or more memories; and
one or more processors operatively coupled to the one or more memories and individually or collectively configured to cause the UE to:
receive, from a base station, information indicating that demodulation reference signal (DMRS) time domain bundling is enabled;
determine a time domain bundling configuration based at least in part on the information indicating that the DMRS time domain bundling is enabled, wherein the time domain bundling configuration includes a dynamic configuration based at least in part on a field in a current PDCCH monitoring occasion that indicates whether a DMRS in a next PDCCH monitoring occasion is bundled with a DMRS in the current PDCCH monitoring occasion; and
perform channel estimation based at least in part on DMRSs received in different physical downlink control channel (PDCCH) monitoring occasions based at least in part on the time domain bundling configuration.
