1. A transmitting wireless communication device in a wireless communication network, comprising:
a transceiver;
a memory; and
a processor coupled to the transceiver and the memory, wherein the processor and the memory are configured to:
transmit a demodulation reference signal (DMRS) bundling indication to a receiving device, the DMRS bundling indication indicating a first capability of the transmitting wireless communication device to support DMRS bundling for channel estimation across two or more slots;
transmit a phase continuity indication indicating a second capability of the transmitting wireless communication device to maintain phase continuity between the two or more slots, wherein the phase continuity indication indicates that the transmitting wireless communication device is capable of maintaining the phase continuity based on the two or more slots being non-consecutive slots; and
transmit a respective set of DMRSs within each of the two or more slots to the receiving device during a DMRS bundling window based on the transmitting wireless communication device and the receiving device each supporting DMRS bundling and the phase continuity indication.
