Abstract
Methods, systems, and devices for wireless communications are described that support demodulation reference signal (DMRS) multiplexing scheme selection for uplink transmission. A user equipment (UE) may monitor for a parameter from a base station indicating which DMRS scheme to use. In some cases, the base station may transmit a radio resource control (RRC) parameter indicating a first DMRS scheme to the UE. The UE may select the first DMRS scheme based on receiving the RRC parameter from the base station or based on a default DMRS scheme. The UE may transmit a transmission based on the first DMRS scheme.
