METHOD AND APPARATUS FOR TRANSMITTING CONTROL INFORMATION IN WIRELESS COMMUNICATION SYSTEM

摘要

A method and apparatus for transmitting control information in a wireless communication system which can support carrier aggregation (CA) are provided. In the method for transmitting control information from a terminal to at least one base station, the terminal receives at least one of a Physical Downlink Control Channel (PDCCH) and a Physical Downlink Shared Channel (PDSCH) from the at least one base station through at least one serving cell configured in the terminal and transmits control information associated with reception of the PDCCH or reception of a PDSCH indicated by the PDCCH to the at least one base station, wherein each of the at least one base station uses a different uplink and downlink configuration (UL-DL configuration) and a uplink-downlink (UL-DL) configuration used in the at least one serving cell can be changed based on a timing determined according to a preset condition.
