Abstract  Abstract

The invention relates to a wireless communication system and further relating to method and device used for transmission/receive uplink control information of link. According to one embodiment of the invention for a terminal in a wireless communication system transmits a confirmation response information method comprising: determining a PUCCH (Physical Uplink Control Channel) format and resource of step wherein in response to downlink transmission comprising a downlink frame of M (M is more than or equal to 1) of downlink subframe set to transmit the confirmation response information and in one uplink subframe using PUCCH format and resource to transmit an acknowledgement response information. Here more than one serving cells are configured to the terminal and the more than one serving cells can include one PCell and at least one SCell. in the determination step when a downlink subframe set there is no SPS (semi-persistent scheduling) release PDCCH (physical downlink control channel). and when through with a PDSCH (Physical Downlink Shared Channel) of detection of PDCCH corresponding to DAI (downlink assignment index) value of 1 indicated can through the PUCCH format 1a/1b is used and in the step of transmitting using the PUCCH format 1a/1b to transmit an acknowledgement response information exists in the downlink subframe set.

The present invention relates to a wireless communication system and more specifically to a method and a device for transmitting/receiving uplink control information. The method for a terminal to transmit confirmation response information in a wireless communication system according to one embodiment of the present invention comprises: a step for determining a PUCCH (physical uplink control channel) format and resource in which confirmation response information is transmitted in response to a downlink transmission in a downlink sub-frame set including M(M?1)downlink sub-frame; and a step for transmitting the confirmation response information using the PUCCH format and resource in one uplink sub-frame. Here one excess serving cell is set to a terminal and the one excess serving cell can include one PCell and at least one SCell. In the determining step the confirmation response information can be transmitted by determining to use a PUCCH format 1a/1b and using the PUCCH format 1a/1b in the transmitting step when a SPS (semi-persistent scheduling) releasing PDCCH (physical downlink control channel) does not exist in the downlink sub-frame set and one PDSCH (physical downlink shared channel) which is indicated through the detection of a corresponding PDCCH having a DAI (downlink assignment index) value of one exists in the downlink sub-frame set.
