Abstract

The present invention relates to a data transmission/receiving method and apparatus in a relay communication system. In particular, the data transmission/receiving method through a backhaul link between a base station and a relay node in a relay communication system comprises: composing a backhaul subframe including a control signal transmission period to which a control signal is allocated and a backhaul signal transmission period to which a backhaul signal is allocated and then allocating the backhaul signal; transmitting configuration information about the backhaul subframe, the information containing symbol position or size data of the backhaul signal transmission period, to the relay node through an upper layer signal; and transmitting the backhaul signal having been allocated through the backhaul subframe to the relay node.

Claims

1. A signal reception method in a wireless communication system, the method comprising:

receiving control information via a second type control channel which is distinguished from a first type control channel, wherein a resource region of the first type control channel is determined by PCFICH (Physical Control Format Indicator Channel);

wherein a starting point of a resource region of the second type control channel is determined by higher-layer signaled information, and

wherein the higher-layer signaled information is commonly used for determining a starting point of a resource region of a data channel.

2. The method of claim 1, wherein the resource region of the data channel is indicated by the second type control channel.

3. The method of claim 1, wherein each starting point of the resource region of the second type control channel and the resource region of the data channel is a first OFDM symbol of each resource region.

4. The method of claim 1, wherein the data channel is a PDSCH (Physical Downlink Shared Channel).

5. A device for use in a wireless communication system, the device comprising:

a transceiver; and

a processor configured to receive control information via a second type control channel which is distinguished from a first type control channel, wherein a resource region of the first type control channel is determined by PCFICH (Physical Control Format Indicator Channel);

wherein a starting point of a resource region of the second type control channel is determined by higher-layer signaled information, and

wherein the higher-layer signaled information is commonly used for determining a starting point of a resource region of a data channel.

6. The device of claim 5, wherein the resource region of the data channel is indicated by the second type control channel.

7. The device of claim 5, wherein each starting point of the resource region of the second type control channel and the resource region of the data channel is a first OFDM symbol of each resource region.

8. The device of claim 5, wherein the data channel is a PDSCH (Physical Downlink Shared Channel).
