Method for controling transmission power using environmental factor

A transmission power control method using an environment parameter for reducing the waste of the unnecessary transmission power while controlling inter cell interference is provided to control transmission power in multiple cell environment and reduce interference between cells. One or more cells exists in one base station(BS). A base station having one or more cell is arranged as a plurality of multi-cell. A serving cell provides a communication service to a user terminal. A non-serving cell is around the serving cell. A plurality of base stations is variously arranged in wireless telecommunications system. The shape and range of cell are variously changed. Signal is transmitted from the terminal to the base station of the serving cell.
