1. A communication method performed by a communication device, the communication method comprising:
- transmitting, by the communication device, a first message to a terminal, the first message indicating that a first subframe is an MBSFN (Multicast Broadcast Single Frequency Network) subframe;
transmitting, by the communication device, a reference signal to the terminal during a first time period of the first subframe; and
receiving, by the communication device, a first data signal comprising first data from a base station during a second time period of the first subframe,wherein the communication device transmits no reference signal to the terminal during the second time period.

Abstract
Disclosed are a data transmission/reception apparatus and method of a wireless communication system using a relay. The data transmission/reception apparatus of the relay sets a relay reception subframe (hereinafter, referred to as ‘relay-rx-subframe’), and reports, to a terminal within a cell coverage, that the set relay-rx-subframe is a Multicast Broadcast Single Frequency Network (MBSFN) subframe, so that a legacy terminal may be provided with services in a wireless communication system using the relay.

19. A method of receiving data by a terminal, comprising:
-
receiving, by the terminal, data from a relay station; receiving, by the terminal, a reference signal from the relay station during a first time period of a first subframe; determining whether the first subframe is an MBSFN (Multicast Broadcast Single Frequency Network) subframe; and disregarding remaining signals from the relay station during a second time period of the first subframe if it is determined that the first subframe is the MBSFN subframe, wherein a first data signal comprising first data is transmitted from a base station to the relay station during the second time period of the first subframe, and the terminal receives no reference signal from the relay station during the second time period. - View Dependent Claims (20, 21, 22, 23, 24, 25)
