1. A method, performed by a terminal supporting carrier aggregation, of monitoring a physical downlink control channel (PDCCH), the method comprising:
receiving, in at least one of a plurality of cells, configuration information including a low power mode indicator that controls monitoring of a PDCCH, in at least one of a plurality of cells and a table including indexes of Y(≤X) cells among a total of X cells;
based on the configuration information, determining whether the low power mode indicator is detected, in at least one cell for which the configuration information is received; and
based on a result of the determining and information about a cell associated with the low power mode indicator, controlling the monitoring of the PDCCH, in a cell associated with the low power mode indicator from among the plurality of cells,
wherein the table is indicated in bits of ceil(log 2(Y)) through L1 signaling.
