Method and apparatus for transmitting receipt acknowledgement in wireless communication system

摘要

The present invention discloses a method for transmitting a reception acknowledgement response in a wireless communication system. The method includes receiving an enhanced physical downlink control channel (EPDCCH), determining a physical uplink control channel (PUCCH) resource based on a lowest one of enhanced control channel element (ECCE) indexes configuring the EPDCCH and a HARQ-ACK resource offset (ARO), and transmitting a reception acknowledgement response through the PUCCH resource. When a reception acknowledgement response related to two or more subframes is transmitted in a subframe for transmission of the reception acknowledgement response, a set of possible values for the ARO includes a first ARO value to shift a PUCCH resource of a specific subframe to a PUCCH resource region for at least one subframe prior to the specific subframe. The first ARO value provides a different shift amount depending on a group having the specific subframe among groups related to the two or more subframes.

1. A method for transmitting a reception acknowledgement response by a user equipment in a wireless communication system, comprising:
receiving an enhanced physical downlink control channel (EPDCCH); and transmitting, through a physical uplink control channel (PUCCH) resource, a reception acknowledgement response for one or more downlink subframes, wherein the PUCCH resource is determined based on a hybrid acknowledgement request-acknowledgement (HARQ-ACK) acknowledgement resource offset (ARO) and a lowest enhanced control channel element (ECCE) index, wherein, when the reception acknowledgement response is related to two or more of the one or more downlink subframes and is to be transmitted in a single subframe, a set of possible values for the HARQ-ACK ARO comprises a first ARO value which shifts a PUCCH resource of a second or later subframe of the two or more downlink subframes to a PUCCH resource corresponding to downlink subframe that is located at least one downlink subframe prior to the second or later subframe, and wherein the first ARO value shifts the PUCCH resource depending on which downlink subframe group the second or later subframe belongs to among downlink subframe groups.
