1. A base station, comprising:
a transceiver; and
a processing system configured to:
determine a first preparation time for a first radio frequency (RF) carrier;
determine a second preparation time for a second RF carrier;
determine a maximum preparation time for at least one uplink transmission based on the first preparation time and the second preparation time; and
transmit, via the transceiver, a grant for the at least one uplink transmission to a user equipment (UE) based on the maximum preparation time, the grant indicating resources for the at least one uplink transmission on the first RF carrier, on the second RF carrier, or on each of the first RF carrier and the second RF carrier.
