Abstract:
1. A method for reporting channel state information (CSI) at a User Equipment (UE) in a wireless communication system, the method comprising: configuring a CSI report set including a first serving cell and a second serving cell, wherein each serving cell comprises a plurality of independently configured subframe subsets; receiving, in a predetermined subframe, a physical downlink control channel (PDCCH) signal requesting an aperiodic CSI report on the CSI report set; and transmitting a physical uplink shared channel (PUSCH) signal including first CSI on the corresponding subframe subset in the first serving cell and second CSI on the corresponding subframe subset in the second serving cell, wherein, if the PDCCH signal includes a 1-bit subframe subset indicator, at least one of the first CSI and the second CSI is calculated based on a subframe subset indicated by the subframe subset indicator.
