An apparatus and method perform Transmit Power Control and Dynamic Frequency Selection (TPC/DFS) during a movement of a Base Station (BS). A network environment around the mobile BS is modeled. Based on the modeling result, a TPC/DFS operation scheme that is most suitable to the mobile BS is selected.

Apparatus and method for transmission power control and dynamic frequency selection during movement of base station

An apparatus and method for power control of a mobile BS of variable backbone capacity. The method includes determining a link state and capacity of a backbone of the BS, and determining a link state and service capacity between the BS and a mobile communication terminal. The method also includes, if the capacity of the backbone is less than the service capacity, setting the backbone capacity similar to the service capacity by lowering a transmit power of the BS by a predefined value.

Apparatus and method for power control of mobile base station of variable backbone capacity
