Method and apparatus for transmitting control information

摘要

A method and apparatus for transmitting uplink control information in an FDD wireless communication system, in which a plurality of cells are arranged, are provided. The method includes: receiving one or more PDCCH signals and one or more PDSCH signals corresponding to the PDCCH signals in downlink subframe N; generating ACK/NACK information on the basis of the result of the acknowledgement of receipt of at least the one or more PDSCH signals; and transmitting the ACK/NACK information through a PUCCH. If a predetermined condition is satisfied, at least one of the PDCCH signals includes information indicating a DAI value, and if the predetermined condition is not satisfied, at least one of the PDCCH signals includes information indicating a value of a PUCCH resource for the ACK/NACK information. The information indicating the DAI value and the information indicating the value of the PUCCH resource are provided in the same field.

1. A method for transmitting an uplink signal from a communication device consisting of a plurality of cells in a frequency division duplex (FDD) wireless communication system, the method comprising the steps of:
receiving one or more physical downlink control channel (PDCCH) signals and one or more physical downlink shared channel (PDSCH) signals corresponding to the PDCCH signals in a downlink subframe N; generating acknowledgement/negative acknowledgement (ACK/NACK) information on the basis of the result of receipt of at least the one or more PDSCH signals; and transmitting the ACK/NACK information through a PUCCH in an uplink subframe N+k where k is a positive integer, wherein, if a predetermined condition is satisfied, at least one of the one or more PDCCH signals includes information indicating a downlink assignment index (DAI) value, wherein, if the predetermined condition is not satisfied, at least one of the one or more PDCCH signals includes information indicating a value of a PUCCH resource for the ACK/NACK information, wherein the predetermined condition includes that the uplink subframe N+k is a subframe for channel state information (CSI) transmission or for scheduling request (SR) transmission, and wherein information indicating the DAI value and the information indicating the value of the PUCCH resource are provided through same field.
