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:

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

receiving resource allocation information from the base station through a physical downlink control channel (PDCCH); and

receiving a predetermined resource block indicated by the resource allocation information among logically contiguous second VRBs in a backhaul subframe,

wherein the logically contiguous second VRBs are re-indexed with valid index numbers in the backhaul subframe only when excluding the one or more first VRBs from an entirety of VRBs,

wherein the logically contiguous second VRBs correspond to a physical downlink shared channel (PDSCH).

2. 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 configured to receive, from the base station, information on one or more first virtual resource blocks (VRBs) allocated for a relay, to receive resource allocation information from the base station through a physical downlink control channel (PDCCH), and to receive a predetermined resource block indicated by the resource allocation information among logically contiguous second VRBs in a backhaul subframe,

wherein the logically contiguous second VRBs are re-indexed with valid index numbers in the backhaul subframe only when excluding the one or more first VRBs from an entirety of VRBs,

wherein the logically contiguous second VRBs correspond to a physical downlink shared channel (PDSCH).
