Apparatus for avoiding dynamic inter-cell interference and method thereof

A method of performing a scheduling in a base station considering an inter-cell interference link formed in accordance with a dynamic scheduling in a mobile communication system, the method comprising:

• transmitting a first step scheduling signal including a user equipment specifying information for specifying a specific user equipment and a contention number information to the specific user equipment;
• and
• transmitting a second step scheduling signal including a resource assignment information on a uplink signal reception or a downlink signal transmission by considering whether a silencing signal for requesting not to perform a resource assignment in a corresponding scheduling stage is received from at least one user equipment including the specific user equipment,
• wherein the silencing signal is received by a base station in a base station list having an inter-cell interference link managed by a user equipment indicated by the user equipment specifying information in the first step scheduling signal of the base station and base stations except a base station having transmitted the contention number information having a highest priority in the corresponding scheduling stage among base stations to which the user equipment indicated by the user equipment specifying information belongs thereto.

A user equipment, which transmits and receives signals by considering an inter-cell interference link formed in accordance with a dynamic scheduling in a mobile communication system, comprising:

• a receiving module receiving a first step scheduling signal including a user equipment specifying information and a contention number information and a second step scheduling signal including a resource assignment information on an uplink signal transmission or a downlink signal reception at least one base station;
• a transmitting module transmitting a silencing signal for requesting not to perform a resource assignment in a corresponding scheduling stage to a specific base station;
• and
• a processor, if the user equipment specifying information in the first step scheduling signal indicates the user equipment, controlling the receiving module and the transmitting module to transmit the silencing signal to base stations in a base station list having an inter-cell interference link applying interference over a predetermined level to the user equipment for a prescribed period and base stations having the user equipment belong thereto except a base station having transmitted the contention number information having a highest priority.

A base station, which performs a scheduling by considering an inter-cell interference link formed in accordance with a dynamic scheduling in a mobile communication system, comprising:

• a transmitting module transmitting a first step scheduling signal including a user equipment specifying information for specifying a specific user equipment and a contention number information and a second step scheduling signal including a resource assignment information on a uplink signal reception or a downlink signal transmission to the specific user equipment;
• a receiving module receiving a silencing signal for requesting not to perform a resource assignment in a corresponding scheduling stage from at least one user equipment including the specific user equipment;
• and
• a processor configured to control the transmitting module to transmit the second step scheduling signal by considering whether the receiving module receives the silencing signal from the at least one user equipment including the specific user equipment,
• wherein the silencing signal is received by a base station in a base station list having an inter-cell interference link managed by a user equipment indicated by the user equipment specifying information in the first step scheduling signal of the base station and base stations except a base station having transmitted the contention number information having a highest priority in the corresponding scheduling stage among base stations to which the user equipment indicated by the user equipment specifying information belongs thereto.
