1. A method of wireless communication performed by an apparatus, the method comprising:
determining to transmit uplink (UL) data in a set of symbols within a subframe;
determining one or more symbols within the set of symbols in which downlink (DL) demodulation reference signals (DMRS) can be received by the apparatus;
determining to align a transmission of UL DMRS with reception of the DL DMRS such that the UL DMRS is transmitted in at least one symbol of the one or more symbols;
receiving, from a base station (BS) in a first set of symbols of the subframe, a first subset of DMRS in a first subset of a physical downlink shared channel (PDSCH), wherein the first set of symbols is non-overlapping in time with an uplink (UL) transmission from the apparatus; and
communicating, with the BS in the set of symbols, the UL data in a physical uplink shared channel (PUSCH) including the UL DMRS in the at least one symbol.
