Title: METHOD AND APPARATUS FOR REPORTING CHANNEL STATUS IN CELLULAR RADIO COMMUNICATION SYSTEM
Abstract:
A method and an apparatus for reporting channel status in a cellular radio communication system are disclosed. In a communication system supporting a carrier aggregation of a component carrier to which an FDD scheme is applied and a component carrier to which a TDD scheme is applied, a base station identifies a TDD uplink-downlink configuration of a TDD primary cell, and configures a CSI transmission period of an FDD secondary cell according to the TDD uplink-downlink configuration. A terminal transmits a CSI of the FDD secondary cell in a specific sub-frame of the TDD primary cell according to a CSI configuration period indicated by the base station.
