    摘要: Provided are a method and a device for executing a hybrid automatic repeat request (HARQ) of a terminal in a time division duplex (TDD)-based wireless communication system. The method comprises the steps of: receiving an uplink grant for a first subframe of a second serving cell through a first serving cell; transmitting uplink data in the first subframe on the basis of the uplink grant; receiving an acknowledgement/not-acknowledgement (ACK/NACK) for the uplink data through the first serving cell; and, when the ACK/NACK signal is a NACK, transmitting a retransmission data for the uplink data in a second subframe of the second serving cell.

    摘要: 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.

    摘要: The present invention relates to a method for a terminal, in which a plurality of serving cells is established, to transmit uplink control information in a wireless communication system. The method comprises the following steps: receiving at least one physical downlink control channel (PDCCH) in a first subframe via a first serving cell from among the plurality of serving cells in a first subframe; receiving at least one physical downlink shared channel (PDSCH) via at least one serving cell from among the plurality of serving cells in the first subframe based on said at least on PDCCH; and transmitting, in a second subframe, an acknowledgement/non-acknowledgement (ACK/NACK) which indicates whether or not a decoding for said at least one PDSCH has succeeded. The ACK/NACK is transmitted using a first resource through only the first serving cell, and transmitted using a second resource in the second subframe if said at least one PDSCH is received through two or more serving cells from among the plurality of serving cells. The first resource is dynamically allocated through the PDCCH which schedules the first serving cell, and the second resource is designated in advance.
