Claim of US Patent No. 11,071,098


1. A method for wireless communication, comprising:receiving at least one grant of communication resources that schedules a plurality of data channels and a plurality of demodulation reference signals (DMRSs), each data channel including one or more DMRSs of the plurality of DMRSs, wherein the plurality of data channels includes at least a first data channel having a first mapping type and a second data channel having a second mapping type;
determining that DMRS sharing between channels of different mapping types associated with the plurality of DMRSs is used;
determining a parameter of each DMRS based at least in part on a DMRS pattern configuration, the DMRS pattern configuration indicating that a first parameter of at least one DMRS of the first data channel is associated with a second parameter of at least one other DMRS of the second data channel based at least in part on determining that the DMRS sharing is used; and
communicating the plurality of DMRSs based at least in part on determining the parameter of each DMRS using the DMRS pattern configuration.
