Abstract

A method and apparatus for performing uplink / downlink (UL / DL) transmission in a flexible subframe are provided. The method includes receiving downlink transmission configuration information in a flexible subframe that is different from configuration information of a subframe that has a fixed duplexing direction; detecting downlink control information transmitted by a base station in the flexible subframe; receiving downlink data corresponding to the downlink control information; and reporting Hybrid Automatic Repeat reQuest ACKnowledgment (HARQ-ACK) for the downlink data and downlink Channel State Indication (CSI) information to the base station.
