1. A method for operating a first user equipment (UE), the method comprising:
determining a first minimum frequency guard band value for use between frequency resources associated with downlink communications between the first UE and a base station, and frequency resources associated with uplink communications between a second UE and the base station;
transmitting to the base station an indication of the first minimum frequency guard band value; and
receiving from the base station a downlink bandwidth part (BWP) allocation for the first UE accommodating the first minimum frequency guard band value;
receiving from the base station a group common downlink control information (GC-DCI) message indicating a change of downlink BWP allocation for the first UE and a change of uplink BWP allocation for the second UE, wherein the changed allocations accommodate the first minimum frequency guard band value; and
in response to determining that a repetition occasion of a downlink transmission from the base station falls within a minimum switching delay associated with the change of downlink BWP allocation, dropping all subsequent repetitions of the downlink transmission.
