Abstract: A user equipment that has performed a random access procedure with respect to a base station may determine a DCI size to be monitored based on DCI size alignment and the base station may determine a DCI size to be used based on the DCI size alignment. The DCI size alignment may include aligning the size of a legacy UL DCI format and the size of a legacy DL DCI format after aligning the size of a new UL DCI format and the size of a new DL UCI format. Each of the new UL DCI format and the legacy UL DCI format is a DCI format used to schedule a physical uplink shared channel (PUSCH), and each of the new DL DCI format and the legacy DL DCI format is a DCI format used to schedule a physical downlink shared channel (PDSCH).
