Abstract

The present invention relates to a method for allocating a relay backhaul resource in a wireless communication system and to an apparatus for same. In detail, the present invention provides a signal-receiving method in which a terminal receives a signal in a wireless communication system, and to an apparatus for same, wherein the method comprises a step of receiving, from a base station, information on one or more first resource blocks (RB) allocated for a relay, a step of receiving resource allocation information through a control channel from the base station, and a step of receiving a predetermined resource block indicated by the resource allocation information among logically continuous second resource blocks. The second resource blocks are logically continuous when excluding said one or more first resource blocks from the entirety of the resource block.

Claims

1. A method for receiving a signal in a user equipment of a wireless communication system, the method comprising the steps of:

receiving, from a base station, information on one or more first resource blocks (RB) allocated for a relay;

receiving resource allocation information from the base station through a control channel; and

receiving a predetermined resource block indicated by the resource allocation information among logically contiguous second resource blocks,

wherein the second resource blocks are logically contiguous when excluding said one or more first resource blocks from the entirety of the resource blocks.

2. The method according to claim 1, wherein the resource blocks include virtual resource blocks (VRBs).

3. The method according to claim 1, wherein the control channel includes a physical downlink control channel (PDCCH).

4. The method according to claim 1, wherein the logically contiguous second resource blocks exist on a backhaul subframe.

5. The method according to claim 1, wherein the logically contiguous second resource blocks correspond to a physical downlink shared channel (PDSCH).

6. A user equipment comprising:

a radio frequency (RF) unit configured to transmit and receive a radio signal to and from a base station; and

a processor receiving, from a base station, information on one or more first resource blocks (RB) allocated for a relay, receiving resource allocation information from the base station through a control channel, and receiving a predetermined resource block indicated by the resource allocation information among logically contiguous second resource blocks,

wherein the second resource blocks are logically contiguous when excluding said one or more first resource blocks from the entirety of the resource blocks.

7. The user equipment according to claim 6, wherein the resource blocks include virtual resource blocks (VRBs).

8. The user equipment according to claim 6, wherein the control channel includes a physical downlink control channel (PDCCH).

9. The user equipment according to claim 6, wherein the logically contiguous second resource blocks exist on a backhaul subframe.

10. The user equipment according to claim 6, wherein the logically contiguous second resource blocks correspond to a physical downlink shared channel (PDSCH).
