Claim of US Patent No. 9,955,489

1. A method of allocating a resource in a small cell system, the method comprising:performing a base station selection for each user and resource allocation that maximize a signal-to-noise-plus-interference ratio (SINR) by using a signal-to-noise ratio (SNR) feedbacked from a user terminal;
broadcasting base station selection for each user and resource allocation information; and
sharing a user terminal data necessary for all small cell base stations by using the resource allocation information and performing a downlink data transmission cooperatively,
wherein performing a base station selection for each user and a resource allocation comprises allocating a first user terminal to a first resource block in a first small cell base station which has a maximum SINR value among resource blocks, and removing slots of the first resource block of a second small cell base station of a second user terminal and a third user terminal, and the first resource block of a third small cell base station, when the first to a third resource blocks exist between the first to the third user terminals, and between the first to the third small cell base stations.
