START SYMBOL DETERMINATION METHOD OF A PHYSICAL DOWNLINK SHARED CHANNEL OF AN EXTENSION CARRIER BETWEEN HETEROGENEOUS NETWORKS AND A MOBILE COMMUNICATION SYSTEM THEREOF FOR DETERMINING A LOCATION FOR A START SYMBOL OF THE PHYSICAL DOWNLINK SHARED CHANNEL OF THE EXTENSION CARRIER IN A HETEROGENEOUS NETWORK BY CONSIDERING A START SYMBOL OF A PHYSICAL DOWNLINK SHARED CHANNEL OF A BACKWARD COMPATIBLE COMPONENT CARRIER IN OTHER NETWORKS

摘要

PURPOSE: A start symbol determination method of a PDSCH(Physical Downlink Shared CHannel) of an EC(Extension Carrier) between heterogeneous networks and a mobile communication system thereof are provided to increase frequency use efficiency and to reduce interference for a PDCCH(Physical Downlink Control CHannel).;CONSTITUTION: A management server(70) manages configuration information and management of subminiature base stations(11-15,21-23,31-33) and macro base stations(10,20,30). The management server performs functions of an SON(Self Organizing and optimizing Network) server(50) and an MME(Mobility Management Entity)(60). The SON server performs installation and optimization of the subminiature base stations and the macro base stations. The SON server provides a basic parameter or data necessary for each base station. The MME manages portability of a terminal(40).;COPYRIGHT KIPO 2013;[Reference numerals] (50) SON server; (70) Management server(O&M); (AA) IP network; (BB) Inter-RAT(WCDMA, CDMA, GSM, etc.)
