    Abstract: The present invention provided a method and apparatus for reporting a channel quality in a wireless communication system. 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 and a device for transmitting an acknowledgement/not-acknowledgement (ACK/NACK) of a terminal which is set with a plurality of serving cells. The method comprises the steps of: receiving data in a subframe n of a second serving cell; and transmitting an ACK/NACK signal for the data in a subframe n+kSCC(n) of a first serving cell connected to the subframe n of the second serving cell, wherein the first serving cell is a primary cell for the terminal to execute an initial connection establishment procedure or a connection reestablishment procedure, and uses a frequency division duplex (FDD) wireless frame, the second serving cell is a secondary cell allocated to the terminal in addition to the primary cell, and uses a time division duplex (TDD) wireless frame, and the kSCC(n) is a previously determined value.

    Abstract: A method of controlling an uplink transmission in a wireless communications system, and a user equipment therefore are discussed. The method according to one embodiment includes configuring the user equipment with multiple component carriers; receiving first configuration information for allocating one or more component carrier sets; receiving second configuration information for periodically transmitting an uplink signal; receiving control information for configuring states of component carriers, by which a downlink component carrier and an uplink component carrier are controlled to be in a same state; and performing a procedure for periodically transmitting the uplink signal on an uplink component carrier in use of the first configuration information, the second configuration information and the control information. When the uplink component carrier is in the active state, a transmission of the uplink signal is performed. When the uplink component carrier is in the non-active state, the transmission of the uplink signal is skipped.
