Abstract: A predetermined number of cyclic shift values are defined for a demodulation of uplink data. An available portion of the cyclic shift values from among the cyclic shift values is transmitted to user equipment. Control information for uplink data is transmitted to the user equipment via a physical control channel. The control information includes information indicating one cyclic shift value for generating a reference signal from among the portion of the cyclic shift values. The user equipment transmits the uplink data based on the control information and a reference signal for a demodulation of the uplink data.

Abstract: 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.
