METHOD OF RECEIVING DATA FROM BASE STATION AT RELAY NODE IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREOF

摘要

A method used by a relay node for receiving a relay node specific downlink physical shared channel from a base station in a multiple antennae wireless communication system is disclosed. More specifically, the method includes the steps of demodulating a relay node specific downlink physical control channel (R-PDCCH) by using a relay node specific reference signal; and, in case a specific downlink information is detected from the demodulated relay node specific downlink physical control channel, of demodulating the relay node specific downlink physical shared channel, under an assumption that the relay node specific downlink physical shared channel is transmitted through a single antenna port by using a predetermined antenna port and scrambling identifier (ID). Herein, the specific downlink control information may correspond to a downlink control information designating a Fallback Mode. And, the predetermined antenna port and scrambling ID may respectively correspond to antenna port 7 and scrambling ID 0.
