1. An apparatus for wireless communication, the apparatus comprising:
a receiver; and
a transmitter configured to transmit a first transmission during a first time slot and to transmit a second transmission during a second time slot that is after the first time slot, wherein the first transmission includes first data and a first demodulation reference signal (DMRS) associated with the first data, wherein the second transmission includes second data and a second DMRS associated with the second data, and wherein one or more of the first transmission or the second transmission further includes an indication of whether a joint channel estimation operation is to be performed based on the first DMRS and the second DMRS, wherein the indication includes a first DMRS group identifier, and wherein the joint channel estimation operation is to be performed based on one or more DMRS associated with the first DMRS group identifier.
