Techniques for retransmission with component carrier switching configuration

A method for wireless communications at a user equipment (UE), comprising:

• receiving, from a base station, a hybrid automatic repeat request (HARQ) retransmission request including a HARQ retransmission offset value indicating a slot of an uplink transmission to be retransmitted, wherein the HARQ retransmission offset value indicates, based at least in part on whether switching component carriers (CCs) is permitted, the slot according to either a first numerology of a first CC or a second numerology of a second CC;
• and
• transmitting, to the base station based on the HARQ retransmission offset value, a retransmission of the uplink transmission in the slot.
