Method and apparatus for transmitting interference information

A method for transmitting, by an eNB, information for interference cancellation of a UE (referred to as a neighboring UE) served by a neighboring eNB, the method comprising:

• transmitting primary control information indicating data for at least one serving UE;
• and
• transmitting assistance control information for interference cancellation,
• wherein the assistance control information includes at least one of CCE indices, an aggregation level and a DCI format of a control channel on which the primary control information is transmitted and CRC bits for the control channel,
• wherein the assistance control information includes sub-assistance control information on neighboring UEs simultaneously scheduled by the eNB.

A UE configured to receive information for interference cancellation, comprising:

• a radio frequency (RF) unit;
• and
• a processor,
• wherein the processor is configured to receive assistance control information for removing interference data from a neighboring eNB and to receive primary control information indicating the interference data using the assistance control information,
• wherein the assistance control information includes at least one of CCE indices, an aggregation level and a DCI format of a control channel on which the primary control information is transmitted and CRC bits for the control channel,
• wherein the assistance control information includes sub-assistance control information on neighboring UEs simultaneously scheduled by the neighboring eNB.

An eNB configured to transmit information for interference cancellation of a UE (referred to as a neighboring UE) served by a neighboring eNB, comprising:

• an RF unit;
• and
• A processor,
• wherein the processor is configured to transmit primary control information indicating data for at least one serving UE and to transmit assistance control information for interference cancellation,
• wherein the assistance control information includes at least one of CCE indices, an aggregation level and a DCI format of a control channel on which the primary control information is transmitted and CRC bits regarding the control channel,
• wherein the assistance control information includes sub-assistance control information about neighboring UEs simultaneously scheduled by the eNB.
