Method for transmitting uplink control information, user equipment, method for receiving uplink control information, and base station

A user equipment for transmitting an uplink signal in a wireless communication system, the user equipment comprising:

• a radio frequency (RF) unit;
• and
• a processor configured to control the RF unit,
• wherein the processor is further configured to:
• control the RF unit to receive an enhanced physical downlink control channel (EPDCCH),
• control the RF unit to receive a physical downlink shared channel (PDSCH) based on the EPDCCH, and
• control the RF unit to transmit acknowledgement/negative acknowledgement (ACK/NACK) information corresponding to the PDSCH using a physical uplink control channel (PUCCH) resource, and
• wherein the PUCCH resource is determined based on an index of an EPDCCH allocation unit included in the EPDCCH and on an index of an antenna port used for the EPDCCH.

A method for receiving an uplink signal by a base station in a wireless communication system, the method comprising:

• transmitting an enhanced physical control channel (EPDCCH) to a user equipment;
• transmitting a physical downlink shared channel (PDSCH) based on the EPDCCH;
• and
• receiving acknowledgement/negative acknowledgement (ACK/NACK) information corresponding to the PDSCH from the user equipment using a physical uplink control channel (PUCCH) resource,
• wherein the PUCCH resource is determined based on an index of an EPDCCH allocation unit included in the EPDCCH and on an index of an antenna port used for the EPDCCH.

A base station for receiving an uplink signal in a wireless communication system, the base station comprising:

• a radio frequency (RF) unit;
• and
• a processor configured to control the RF unit,
• wherein the processor is further configured to:
• control the RF unit to transmit an enhanced physical downlink control channel (PDCCH) to a user equipment,
• control the RF unit to transmit a physical downlink shared channel (PDSCH) based on the EPDCCH, and
• control the RF unit to receive acknowledgement/negative acknowledgement (ACK/NACK) information corresponding to the PDSCH from the user equipment using a physical uplink control channel (PUCCH) resource, and
• wherein the PUCCH resource is determined based on an index of an EPDCCH allocation unit included in the EPDCCH and on an index of an antenna port used for the EPDCCH.
