用于在蜂窝无线电通信系统中报告信道状态的方法和装置
Abstract:
公开了用于在蜂窝无线电通信系统中报告信道状态的方法和装置。在支持应用FDD方案的分量载波和应用TDD方案的分量载波的载波聚合的通信系统中，基站识别TDD主小区的TDD上行链路‑下行链路配置，并且根据该TDD上行链路‑下行链路配置来配置FDD辅小区的CSI传输时段。终端根据基站所指示的CSI配置时段在TDD主小区的特定子帧中传输FDD辅小区的CSI。
Abstract(English):

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.
