Abstract
A method and apparatus for transmitting feedback information is provided for use in a Cooperative Multi-Point downlink transmission of multiple base stations efficiently. An interference measurement method of a base station in a mobile communication system, the method comprising: allocating at least one Interference Measurement Resource (IMR) to a terminal; transmitting the allocated IMR to the terminal; and receiving at least one channel status information from the terminal; wherein allocating at least one IMR comprises allocating at least one IMR for the terminal overlapped to other IMR for the other terminal.
Claims12
An interference measurement method of a base station in a mobile communication system, the method comprising:
- transmitting by the base station first information for a first interference measurement resource (IMR) having a randomized pattern and second information for a second IMR having a non-randomized pattern to a terminal;
- transmitting a resource block (RB) including the first IMR and the second IMR to the terminal;
- and
- receiving at least one channel status information from the terminal, wherein the at least one channel status information is generated using an interference measured by the terminal based on the first IMR and second IMR.
An interference measurement method of a terminal in a mobile communication system, the method comprising:
- receiving by the terminal first information for a first interference measurement resource (IMR) having a randomized pattern and second information for a second IMR having a non-randomized pattern, set from a base station;
- receiving a resource block (RB) including the first IMR and the second IMR from the base station;
- measuring an interference based on the first IMR and the second IMR;
- and
- transmitting at least one channel status information to the base station, wherein the at least one channel status information is generated using the measured interference.
A base station of a mobile communication system, the base station comprises:
- a transceiver configured to transmit and receive signals to and from a terminal;
- and
- a control unit configured to:
- control the transceiver to transmit first information for a first interference measurement resource (IMR) having a randomized pattern and second information for a second IMR having a non-randomized pattern to the terminal,
- control the transceiver to transmit a resource block (RB) including the first IMR and the second IMR to the terminal, and
- control the transceiver to receive at least one channel status information from the terminal, wherein the at least one channel status information is generated using an interference measured by the terminal based on the first IMR and second IMR.
A terminal of a mobile communication system, the terminal comprising:
- a transceiver configured to transmit and receive signals to and from a base station;
- and
- a control unit configured to:
- control the transceiver to receive first information for a first interference measurement resource (IMR) having a randomized pattern and second information for a second IMR having a non-randomized pattern, from the base station,
- control the transceiver to receive a resource block (RB) including the first IMR and the second IMR from the base station,
- measure an interference based on the first IMR and the second IMR, and
- control the transceiver to transmit at least one channel status information to the base station, wherein the at least one channel status information is generated using the measured interference.
