Abstract

The present invention relates to an apparatus and a method for transiting uplink control information for a terminal which transits downlink control information through downlink control information introduced to a data region and receives this information. The present invention relates to a method for mapping an uplink control channel resource for the uplink HARQ ACK / NACK feedback of a terminal to the downlink data channel through the downlink scheduling information transited through the downlink control channel, and a terminal thereof. [Reference numerals] (S1010) Transiting downlink; (S1020) Transiting uplink

Description

technical field [0001] The present disclosure relates to transmitting control information at a transmission / reception point and to mapping uplink control channel resources at a user terminal. In particular, the present disclosure relates to an uplink channel of a user equipment for transmitting downlink control information through a newly adopted (or defined) downlink control channel in a data region and transmitting the downlink control information. Methods and apparatus for controlling information. Also, the present disclosure relates to a method and apparatus for performing Physical Uplink Control Channel (PUCCH) resource mapping for uplink HARQ-ACK / NACK feedback of a user equipment. Herein, the user equipment may perform uplink HARQ-ACK / NACK feedback in response to a downlink data channel allocated according to downlink scheduling information transmitted through such a new downlink control channel. Background technique [0002] Wireless communication systems have been ...
