1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
transmitting, to a base station, capability information associated with a carrier aggregation, wherein the capability information includes first information indicating a first maximum number of a component carrier (CC) associated with a physical downlink control channel (PDCCH) monitoring;
receiving, from the base station, configuration information associated with downlink control information (DCI) formats;
executing a first step of a DCI size alignment, wherein the first step comprises aligning a size of a DCI format 0-x for an uplink scheduling with a size of a DCI format 1-x for a downlink scheduling, in case that a total number of different DCI sizes configured to monitor is more than four or a total number of different DCI sizes with a cell-radio network temporary identifier (C-RNTI) configured to monitor is more than three; and
executing a second step of the DCI size alignment, wherein the second step comprises aligning a size of a DCI format 0-1 for the uplink scheduling with a size of a DCI format 1-1 for the downlink scheduling, in case that, after the first step, a total number of different DCI sizes configured to monitor is more than four or a total number of different DCI sizes with a cell-radio network temporary identifier (C-RNTI) configured to monitor is more than three,
wherein the DCI format 0-x is different from the DCI format 0-1 and the DCI format 1-x is different from the DCI format 1-1.
