A terminal receives an uplink grant from a base station via one of a plurality of downlink component carriers (CCs). The uplink grant includes a channel quality indicator (CQI) request for instructing uplink allocation and CQI reporting. The terminal reports the CQI of the downlink CC being linked to the base station. The downlink CC being linked is one of the plurality of downlink CCs, which is linked to the uplink CC for which the uplink allocation is scheduled.id='REI-00001' id='REI-00002' date='20180911' A method and an apparatus for reporting channel quality are discussed. The method according to an embodiment includes receiving, by a terminal configured with a plurality of downlink component carriers (CCs), control information from a base station, the control information including an uplink allocation and a CQI request, the control information including a carrier indicator field (CIF) indicating an uplink CC in which the uplink allocation is scheduled; and transmitting, by the terminal to the base station, the CQI through an uplink CC. The CQI request indicates one of: a triggering of CQI reporting for one downlink CC linked to the uplink CC, indicated by the CIF, among the plurality of downlink CCs; and a triggering of CQI reporting for a first group of downlink CCs among the plurality of downlink CCs. id='REI-00002'
