In order to cope with rapid increase of mobile communication demands in recent days, it is required for transmission link systems to have much higher capacity as well as more efficient traffic handling capability. Also economical equipment design and high reliability hava become important factors in constructing the network infrastructure. This paper describes basic design policy for DoCoMo's transmission networks, outline of new radio-relay systems and multiplexing equipment, and requirements for link systems toward the introduction of IMT-2000 in the near future.
