MOBILE COMMUNICATION SYSTEM, BASE STATION AND COMMUNICATION CONTROL METHOD
First Claim
1. A mobile communication system in which a plurality of base stations included in a CoMP cooperating set allocate a same communication resource to a user terminal to perform communication, whereineach of the plurality of base stations comprisesa notification unit that notifies another base station included in the CoMP cooperating set of a communication resource of allocation candidate for the user terminal in the base station itself;
- a receiver that receives a notification of a communication resource of allocation candidate for the user terminal in the other base station included in the CoMP cooperating set from the other base station; and
a disabling unit that performs setting to disable allocation of a communication resource of allocation candidate, depending on a reception state of the receiver.

Abstract
In a mobile communication system in which a plurality of base stations included in a CoMP cooperating set allocate a same communication resource to a user terminal to perform a communication, each of the plurality of base stations comprises a notification unit that notifies another base station included in the CoMP cooperating set of a communication resource of allocation candidate for the user terminal in the base station itself; a receiver that receives a notification of a communication resource of allocation candidate for the user terminal in another base station included in the CoMP cooperating set from the other base station; and a disabling unit that performs setting to disable allocation of a communication resource of allocation candidate, depending on a reception state of the receiver.

4. A base station included in a plurality of base stations forming a CoMP cooperating set in a mobile communication system in which the plurality of base stations perform communication with a user terminal by allocating a same communication resource to the user terminal, comprising:
-
a notification unit that notifies another base station included in the CoMP cooperating set of a communication resource of allocation candidate for the user terminal in the base station itself; a receiver that receives a notification of the communication resource of allocation candidate for the user terminal in the other base station included in the CoMP cooperating set from the other base station; and a disabling unit that performs setting to disable allocation of a communication resource of allocation candidate, depending on a reception state of the receiver.

5. A communication control method in a mobile communication system in which a plurality of base stations included in a CoMP cooperating set perform communication with a user terminal by allocating a same communication resource to the user terminal, the method comprising:
-
in each of the plurality of base stations, a step A of notifying another base station included in the CoMP cooperating set of a communication resource of allocation candidate for the user terminal in the base station itself; a step B of receiving a notification of a communication resource of allocation candidate for the user terminal in the other base station included in the CoMP cooperating set from the other base station; and a step C of disabling allocation of a communication resource of allocation candidate, depending on a reception state at the step B.
