Abstract
A method and apparatus for transmitting control information is provided for use in detection of interference an signal in a wireless communication system. An interference control method of a base station of a mobile communication system includes scheduling data to be transmitted to a terminal and transmitting control information including data channel information on the scheduled data and interference signal information to the terminal.
Claims12
A method by a base station of a mobile communication system, the method comprising:
- identifying downlink control information including first information related to scheduling data, second information on a second reference signal of a cell associated with the base station being quasi co-located with a first reference signal of an interference signal, and third information on a scrambling sequence of the first reference signal of the interference signal;
- and
- transmitting, to a terminal, the identified downlink control information,
- wherein the first reference signal of the interference signal comprises a demodulation reference signal (DMRS) of the interference signal, and
- wherein the second reference signal of the cell associated with the base station further comprises at least one of a channel status information reference signal (CSI-RS) and a cell-specific reference signal (CRS).

A method by a terminal in a wireless communication system, the method comprising:
- receiving, from a base station, downlink control information including first information related to scheduling data, second information on a second reference signal of a cell associated with the base station being quasi co-located with a first reference signal of an interference signal, and third information on a scrambling sequence of the first reference signal of the interference signal;
- and
- receiving, from the base station, the data based on the downlink control information,
- wherein the first reference signal of the interference signal comprises a demodulation reference signal (DMRS) of the interference signal, and
- wherein the second reference signal of the cell associated with the base station further comprises at least one of a channel status information reference signal (CSI-RS) and a cell-specific reference signal (CRS).

A base station in a mobile communication system, the base station comprising:
- a transceiver configured to transmit and receive at least one signal;
- and
- a controller coupled with the transceiver and configured to:
- identify downlink control information including first information related to scheduling data, second information on a second reference signal of a cell associated with the base station being quasi co-located with a first reference signal of an interference signal, and third information on a scrambling sequence of the first reference signal of the interference signal, and
- transmit, to the terminal, the identified downlink control information,
- wherein the first reference signal of the interference signal comprises a demodulation reference signal (DMRS) of an interference signal, and
- wherein the second reference signal of the cell associated with the base station further comprises at least one of a channel status information reference signal (CSI-RS) and a cell-specific reference signal (CRS).
