Abstract: A method for transmitting channel status information of a user equipment (UE) in a wireless communication system. The UE reports first channel information to a base station periodically; and reports second channel information to the base station periodically. The first channel information and the second channel information are pieces of information combined to indicate one precoding matrix. The second channel information reported in a specific subframe is calculated based on last reported first channel information. A channel quality indicator (CQI) reported in the specific subframe is calculated based on one precoding matrix indicated by the last reported first channel information and the second channel information reported in the specific subframe.

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. 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.

Abstract: Provided are a method for a terminal transmitting uplink control information (UCI) through a physical uplink control channel (PUCCH) in a wireless communication system, and a terminal using the method. A transmission power to be applied to the uplink control channel is determined on the basis of a value subordinate to a PUCCH format, and at least one type of UCI is transmitted from the physical uplink control channel by using the transmission power that is determined, wherein when the PUCCH format is PUCCH format 3, and the at least one type of UCI includes acknowledgement/negative-acknowledgement(ACK/NACK) and periodic channel state information (CSI), the value subordinate to the PUCCH format is determined on the basis of the number of bits of the ACK/NACK and the number of bits of the periodic CSI.
