APPARATUS AND METHOD FOR TRANSMITTING CHANNEL STATE INFORMATION IN WIRELESS COMMUNICATION SYSTEM

摘要

The present invention relates to an apparatus and method for transmitting channel state information in a wireless communication system. This specification discloses a UE including: a reception unit for receiving coordination mode activation information indicating an ICIC mode to restrict a measurement of a channel state, and receiving CSI request information requesting aperiodic transmission of the CSI, a UE configuration control unit for switching a state of the UE to the ICIC mode based on the coordination mode activation information and for configuring one or more serving cells in the UE, a measurement unit for measuring a channel state for a subset in an activated serving cell from among the configured one or more serving cells based on the CSI request information, an information generation unit for generating CSI regarding the measured channel state, and a transmission unit for transmitting the generated CSI to the BS.
