1. A method for wireless communications, the method comprising:
determining a set of demodulation reference signal (DM-RS) configuration information, each DM-RS configuration information corresponding to a respective carrier segment of a set of carrier segments, wherein each respective carrier segment is used for transmitting a respective physical data shared channel (PDSCH) transmission, and wherein each respective DM-RS configuration information indicates one or more DM-RS parameters that are used to determine a respective DM-RS structure for each respective carrier segment, and wherein the respective DM-RS structure for each respective carrier segment comprises a different mapping of one or more DM-RSs to physical resources associated with a corresponding PDSCH; and
transmitting a PDSCH transmission in at least one carrier segment of the set of carrier segments, wherein the transmitted PDSCH transmission comprises the one or more DM-RSs that are in accordance with the respective DM-RS structure for the at least one carrier segment.
