Abstract
The present invention relates to a wireless communication system. And, a method of transmitting and receiving channel status information on a multi-cell operation in a wireless communication system and apparatus for the same are disclosed. The present invention may include determining a report type of channel status information on multi-cell operation and transmitting/receiving the channel status information corresponding to the determined channel status information report type via uplink data channel.
Claims15
A method of transmitting CSI (channel status information) at a user equipment in a wireless communication system, the method comprising:
- determining at least one CSI report type for the CSI used for multi-cell operation;
- and
- transmitting the CSI corresponding to one of the at least one CSI report type to a base station via uplink data channel.
The method of claim 10, wherein each of the 1st cell set and the 2nd cell set comprises at least one cell among a serving cell and at least one coordinating cell joining the multi-cell operation.
A method of receiving CSI (channel status information) at a base station in a wireless communication system, the method comprising:
- determining at least one CSI report type for the CSI used for multi-cell operation;
- and
- receiving the CSI corresponding to one of the at least one CSI report type from a user equipment via uplink data channel.
A user equipment for transmitting CSI (channel status information) in a wireless communication system, the user equipment comprising:
- a receiving module receiving a downlink signal from a base station;
- a transmitting module transmitting an uplink signal to the base station;
- and
- a processor controlling the user equipment including the receiving module and the transmitting module,
- wherein the processor is configured to:
- determine at least one CSI report type for the CSI used for multi-cell operation;
- transmit the CSI corresponding to one of the at least one CSI report type to the base station via uplink data channel using the transmitting module.
A base station for receiving CSI (channel status information) in a wireless communication system, the base station comprising:
- a receiving module receiving an uplink signal from a user equipment;
- a transmitting module transmitting a downlink signal to the user equipment;
- and
- a processor controlling the base station including the receiving module and the transmitting module,
- wherein the processor is configured to:
- determine at least one CSI report type for the CSI used for multi-cell operation;
- receive the CSI corresponding to one of the at least one CSI report type from the user equipment via uplink data channel using the receiving module.
