Demodulation reference signal configuration for uplink messages

A method for wireless communications at a network entity, comprising:

• transmitting control signaling indicating a demodulation reference signal configuration for an uplink message, wherein the control signaling further indicates that a user equipment (UE) is to refrain from including demodulation reference signals in at least a first portion of the uplink message based at least in part on the demodulation reference signal configuration;
• receiving the uplink message without the demodulation reference signals in at least the first portion of the uplink message in accordance with the demodulation reference signal configuration;
• and
• decoding the uplink message based at least in part on the demodulation reference signal configuration.

An apparatus for wireless communications at a user equipment (UE), comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive control signaling indicating a demodulation reference signal configuration for an uplink message, wherein the control signaling further indicates that the UE is to refrain from including demodulation reference signals in at least a first portion of the uplink message based at least in part on the demodulation reference signal configuration;
• encode the uplink message without the demodulation reference signals in at least the first portion of the uplink message in accordance with the demodulation reference signal configuration;
• and
• transmit the uplink message based at least in part on encoding the uplink message.
