Downlink control information size adjustment based on unified transmission configuration indicator state

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

• transmitting, to a user equipment (UE), a first control message including a mapping of at least one transmission configuration indicator codepoint to two transmission configuration indicator states;
• transmitting, to the UE, downlink control information message that schedules an uplink shared channel transmission, the downlink control information message including a first set of fields specifying configuration information for a first set of repetitions of the uplink shared channel transmission and an additional second set of fields specifying configuration information for a second set of repetitions of the uplink shared channel transmission, the additional second set of fields included in the downlink control information message based at least in part on the first control message including the mapping;
• and
• receiving, from the UE, the uplink shared channel transmission in accordance with the downlink control information message.

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

• a processor;
• memory in electronic communication with the processor;
• and
• instructions stored in the memory, wherein the instructions are executable by the processor to:
• receive a first control message including a mapping of at least one transmission configuration indicator codepoint to two transmission configuration indicator states;
• receive a downlink control information message that schedules an uplink shared channel transmission, the downlink control information message including a first set of fields specifying configuration information for a first set of repetitions of the uplink shared channel transmission and an additional second set of fields specifying configuration information for a second set of repetitions of the uplink shared channel transmission, the additional second set of fields included in the downlink control information message based at least in part on the first control message including the mapping;
• and
• transmit the uplink shared channel transmission in accordance with the downlink control information message.
