Methods, systems, and devices for wireless communication are described. In some systems, a user equipment (UE) may support multiple communications schemes, including a time division multiplexing (TDM) scheme, a frequency division multiplexing (FDM) scheme, a spatial division multiplexing (SDM) scheme, and a single transmission/reception point (sTRP) scheme. The UE may receive control signaling that indicates the multiple communications schemes and downlink control information (DCI) that schedules an uplink data message. The DCI may indicate one or more sounding reference signal (SRS) resource sets associated with the uplink data message. The UE may transmit the uplink data message in accordance with a switching arrangement for switching between the communications schemes. The switching arrangement may be indicated for the uplink data message by one or more of the control signaling, the DCI, or the one or more SRS resource sets.
