RADIO BASE STATION APPARATUS, MOBILE TERMINAL APPARATUS, RADIO COMMUNICATION METHOD AND RADIO COMMUNICATION SYSTEM

摘要

The present invention is designated to improve received quality in a mobile terminal apparatus when coordinated multiple-point transmission (CoMP)-in particular, DCS-CoMP-is adopted. With the radio communication method of the present invention, when dynamic cell selection-type coordinated multiple-point transmission is adopted, a radio base station apparatus increases transmission power in radio resources to transmit to a mobile terminal apparatus, transmits the increased transmission power to the mobile terminal apparatus as transmission power information and performs dynamic cell selection-type coordinated multiple-point transmission at the increased transmission power.
