    摘要: The present invention provides a method and apparatus for transmitting UCI (uplink control information) by user equipment in a carrier aggregation system. According to the method, the user equipment transmits UCI through a PUSCH (physical uplink shared channel) of a primary cell in a subframe that has PUSCH transmission of the primary cell; and if the subframe that does not have the PUSCH transmission of the primary cell has PUSCH transmission of at least one secondary cell, the user equipment transmits the UCI through the PUSCH of one of the at least one secondary cell. In this case, more than one serving cell is set up in the user equipment; simultaneous transmission of PUSCH and PUCCH (physical uplink control channel), with PUSCH being a data channel and PUCCH being a control channel, is not set up in the serving cells; and each of the serving cells includes the primary cell and the at least one secondary cell.

    摘要: A method and device for transmitting acknowledgement/non-acknowledgement (ACK/NACK) by User Equipment (UE) for which a plurality of serving cells has been configured in a wireless communication system operating in Time Division Duplex (TDD). The method includes: configuring a plurality of serving cells; receiving a codeword through at least one of the plurality of configured serving cells; and transmitting ACK/NACK information indicative of reception acknowledgement for the codeword. Here, if the UE receives the codeword through only a first serving cell of the plurality of configured serving cells, the UE transmits the ACK/NACK information according to a first transmission scheme, and the first transmission scheme is a scheme for sending ACK/NACK when the UE receives only one configured serving cell.

    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.
