Abstract
A method and an apparatus for feeding back channel state information (CSI) of user equipment (UE) in a communication system are disclosed. The method comprises the steps of: receiving, from a base station, configuration information related to a plurality of CSI reports; identifying the setting of the plurality of CSI reports corresponding to a plurality of measurement resources, on the basis of the configuration information; generating a first CSI report corresponding to a first measurement resource and a second CSI report corresponding to a second measurement resource when the plurality of CSI reports are set; and transmitting the first CSI report and the second. CSI report to the base station.

A method of transmitting channel state information (CSI) by a user equipment (UE) in a communication system, the method comprising:
- receiving, from a base station (BS), configuration information via radio resource control (RRC) signaling, the configuration information comprising information indicating whether CSI feedback based on further enhancements to coordinated multipoint (feCoMP) is enabled;
- generating at least one CSI based on the CSI feedback based on feCoMP, in response to the information indicating that the CSI feedback based on feCoMP is enabled;
- and
- transmitting the generated CSI to the BS.
A user equipment (UE) that transmits channel state information (CSI) in a communication system, the UE comprising:
- a transceiver configured to receive, from a base station (BS), configuration information via radio resource control (RRC) signaling, the configuration information comprising information indicating whether CSI feedback based on further enhancements to coordinated multipoint (feCoMP) is enabled;
- and
- a processor configured to generate at least one CSI based on the CSI feedback based on feCoMP, in response to the information indicating that the CSI feedback based on feCoMP is enabled.
A method of receiving channel state information (CSI) by a base station (BS) in a communication system, the method comprising:
- transmitting, to a user equipment (UE), configuration information via radio resource control (RRC) signaling, the configuration information comprising information indicating whether CSI feedback based on further enhancements to coordinated multipoint (feCoMP) is enabled;
- receiving at least one CSI from the UE based on the CSI feedback based on feCoMP, in response to the information indicating that the CSI feedback based on feCoMP is enabled;
- and
- processing the at least one CSI based on the configuration information.
A base station (BS) that receives channel state information (CSI) in a communication system, the BS comprising:
- a transceiver configured to transmit, to a user equipment (UE), configuration information via radio resource control (RRC) signaling, the configuration information comprising information indicating whether CSI feedback based on further enhancements to coordinated multipoint (feCoMP) is enabled, and receive at least one CSI from the UE based on the CSI feedback based on feCoMP, in response to the information indicating that the CSI feedback based on feCoMP is enabled;
- and
- a processor configured to process at least one CSI based on the configuration information.
