WIRELESS COMMUNICATION SYSTEM USING MULTIPLE TRANSMISSION AND RECEPTION POINT

摘要

PURPOSE: A wireless communication system using multiple transmission and reception points is provided to offer a physical channel transmission method and a reference signal transmission method for downlink communication using a plurality of transmission and reception points. CONSTITUTION: A wideband transmission and reception point(130) includes a wide transmission area(131) which is wider than one or more narrowband transmission and reception points(150). The wideband transmission and reception point and the one or more narrowband transmission and reception points creates a downlink transmission signal using physical cell ID(Identification). The wideband transmission and reception point uses high transmission power. The narrowband transmission and reception point uses power which is lower than the wideband transmission and reception band.
