Method and apparatus for enhanced control channel-based operation in wireless communication system

摘要

The present invention relates to a wireless communication system, and more specifically, to a method and an apparatus for enhanced-control channel-based operation. A method for a terminal for transmitting confirmation response information in a wireless communication system according to one embodiment of the present invention comprises a step for transmitting confirmation response information for a downlink data channel by means of an uplink control channel resource, wherein an index for the uplink control channel resource can be determined on the basis of a delegate antenna port of a downlink control channel derived from the identifier of the terminal.

主权项

1. A method of transmitting acknowledgement/negative-acknowledgement (ACK/NACK) by a user equipment (UE) in a wireless communication system, the method comprising:
receiving an Enhanced Physical Downlink Control Channel (EPDCCH); receiving a downlink (DL) data channel based on the EPDCCH; and transmitting ACK/NACK to the DL data channel using an uplink (UL) control channel resource, wherein the UL control channel resource is determined based on n*+k+NoffsetPUCCH; n* is a value corresponding to a lowest ECCE index used to the EPDCCH; k is a value corresponding to an index of the antenna port used for the EPDCCH; and NoffsetPUCCH is a specific offset value indicating a starting offset of the UL control channel resource via higher layer signaling.
