1. A method of transmitting downlink control information (DCI) by a base station (BS) in a wireless communication system, the method comprising:
performing DCI size alignment to adjust DCI sizes of DCI formats to be monitored by a user equipment (UE); and
transmitting at least one DCI based on the DCI size alignment,
wherein performing the DCI size alignment comprises:
aligning a size of a new uplink (UL) DCI format and a size of a new downlink (DL) DCI format with a first DCI size; and
aligning a size of a legacy UL DCI format and a size of a legacy DL DCI format with a second DCI size, based on i) aligning the size of the new UL DCI format and the size of the new DL DCI format with the first DCI size and ii) a total number of different DCI sizes to be monitored by the UE exceeding a predetermined number for a cell,
wherein 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
wherein 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).
