Abstract:
Provided are a method and apparatus for transmitting channel status information (CSI) of a user equipment (UE) in a carrier aggregation system. The method includes: receiving an uplink grant including a CSI request field from a base station (BS); and transmitting aperiodic CSI for a first serving cell, a first serving cell set or a second serving cell set according to a bit value of the CSI request field to the BS via the first serving cell.
