Method and device for inter-cluster cooperative communication in mobile communication system

A method for operating a base station in a mobile communication system, the method comprising:

• transmitting, to a central unit, information regarding channels of a sector of the base station and at least one sector in at least one neighboring cluster;
• receiving, from the central unit, information on a blank pattern;
• and
• performing a scheduling based on the blank pattern,
• wherein the blank pattern is determined based on the information regarding the channels and information regarding a change in an utility of the at least one sector of the base station due to a transition of the sector from a blank state into a non-blank state,
• wherein the utility is determined based on a ratio of a current data rate to an average data rate.

A central unit in a communication system, the central unit comprising:

• an interface unit configured to:
• receive first information regarding channels of a sector in a serving cluster and at least one sector in at least one neighboring cluster, and
• receive second information regarding a change in an utility of the at least one sector due to a transition of the sector in the serving cluster base station from a blank state into a non-blank state;
• and
• a controller configured to:
• determine a blank pattern of the sector in the serving cluster based on the first information and the second information,
• wherein the utility is determined based on a ratio of a current data rate to an average data rate.

A base station in a mobile communication system, the base station comprising:

• a transmitter configured to transmit, to a central unit, information regarding channels of a sector of the base station and at least one sector in at least one neighboring cluster;
• a receiver configured to receive, from the central unit, information on a blank pattern;
• and
• a scheduler configured to perform a scheduling based on the blank pattern,
• wherein the blank pattern is determined based on the information regarding the channels and information regarding a change in an utility of the at least one sector due to a transition of the sector of the base station from a blank state into a non-blank state,
• wherein the utility is determined based on a ratio of a current data rate to an average data rate.
