METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING DATA IN A WIRELESS COMMUNICATION SYSTEM

摘要

PURPOSE: A method and an apparatus are provided to decode so that UE[User Equipment]receives data accurately by transmitting information about a wireless resource used for transmitting data in a wireless communication system in which CoMP[Coordinated Multi-Point transmission/reception]method is used to UE, and efficiently utilize time and frequency resources. CONSTITUTION: A method in which UE receives data in a wireless communication system using a CoMP method includes a process receiving DCI[Downlink Control Information]including CoMP control information; a process determining the start location of the data channel of wireless resource based on the start location information of a data channel used in each of multiple cells included in CoMP control information; and a process receiving data from multiple cells in the determined start location. [Reference numerals] (800) Receiving DCI using PDCCH or E-PDCCH; (810) Including CFI in the DCI?; (820) CoMP related control information = '00' ?; (830) Using a PDSCH starting position value directed by the CoMP related control information; (840) Using the PDSCH starting position value designated by CFI; (AA,CC) No; (BB,DD) Yes;
