Claim 10:
11. A method in a base station, the method comprising:
transmitting, to a radio terminal, downlink control information (DCI) including a first field for indicating frequency domain resources allocated to the radio terminal and a second field for indicating time domain resources allocated to the radio terminal;
changing the size of the second field for indicating the time domain resources based on at least one of:
subcarrier spacing of Synchronisation Signals/Physical Broadcast Channel (SS/PBCH) blocks associated with a cell in which the base station communicates with the radio terminal;
a time domain transmission pattern of the SS/PBCH blocks;
a frequency range to which the SS/PBCH blocks belong; or
a number of reference signals used for measuring a quality of multiple beams transmitted in the cell; and

reducing a size of the first field as a size of the second field increases.
