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-sub-frame’), and reports, to a terminal within a cell coverage, that the set relay-rx-subframe is a Multicast Broadcast Single Frequency Network (MBSFN) sub-frame, so that a legacy terminal may be provided with services in a wireless communication system using the relay.

Claims

1. A method for data relay in a relay station, comprising:

obtaining information about a relay reception subframe;

signaling to a terminal that the relay reception subframe is an MBSFN (Multicast Broadcast Single Frequency Network) subframe; and

receiving data from a base station during the relay reception subframe,

wherein the relay reception subframe includes a first period for transmitting a reference signal or a control signal to the terminal and a second period for receiving data by the relay station from the base station.

2. The method of claim 1, wherein the relay reception subframe is set by the base station.

3. The method of claim 1, wherein the relay reception subframe is set by the relay station or by cooperation between the base station and the relay station.

4. The method of claim 1, wherein the relay station transmits 1) no reference signal or no control signal, 2) one reference signal or one control signal, or 3) two reference signal or two control signal to the terminal during the first period.

5. A method for data transmission in a base station, comprising:

setting a relay reception subframe for transmission from base station to relay station;

transmitting information about the relay reception subframe to a relay station; and

transmitting data to the relay station during the relay reception subframe,

wherein the relay reception subframe is configured as an MBSFN (Multicast Broadcast Single Frequency Network) subframe,

wherein the relay reception subframe includes a first period for relay transmission and a second period for relay reception,

wherein the reference signal or the control signal is transmitted from the relay station to terminal during the first period and data is transmitted from the base station to the relay station and the data is received by the relay station during the second period.

6. The method of claim 5, wherein the relay reception subframe includes a first period for relay transmission and a second period for relay reception.

7. A method for data reception in a terminal, comprising:

receiving data from a relay station; and

receiving a reference signal or a control signal from the relay station during a relay reception subframe configured as an MBSFN (Multicast Broadcast Single Frequency Network) subframe,

wherein the relay reception subframe includes a first period for relay transmission and a second period for relay reception,

wherein the reference signal or the control signal is received from the relay station during the first period and data is transmitted from the base station to the relay station and the data is received by the relay station during the second period.

8. The method of claim 7, wherein the terminal receives 1) no reference signal or no control signal, 2) one reference signal or one control signal, or 3) two reference signal or two control signal from the relay station during the first period.

9. The method of claim 7, wherein the relay reception subframe is configured by a base station.
