Physical shared channel reference signal bundling

A method for wireless communication at a base station, comprising:

• determining, for a user equipment (UE), a demodulation reference signal bundling configuration for one or more physical shared channels;
• transmitting, to the UE, an indication of the demodulation reference signal bundling configuration;
• receiving, from the UE based at least in part on transmitting the indication, an indication of a UE capability for demodulation reference signal bundling for the one or more physical shared channels;
• and
• transmitting, to the UE based at least in part on receiving the indication of the UE capability, downlink control information.

An apparatus for wireless communication 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, from a base station, an indication of a demodulation reference signal bundling configuration for one or more physical shared channels;
• transmit, to the base station based at least in part on receiving the indication, an indication of a UE capability for demodulation reference signal bundling for the one or more physical shared channels;
• receive, from the base station based at least in part on transmitting the indication of the UE capability, downlink control information;
• determine, based at least in part on the downlink control information, whether to alter a parameter associated with or more physical shared channel symbols associated with the one or more physical shared channels;
• and
• transmit, to the base station based at least in part on determining whether to alter the parameter, one or more bundled demodulation reference signals associated with the one or more physical shared channel symbols.
