Abstract

The present invention relates to wireless communication, and more particularly, to a method for transmitting a signal using a plurality of antenna ports and a transmission end apparatus for same. According to a method for a transmission end transmitting the signal in a multi-input multi-output (MIMO) wireless communication system of the present invention, a step of transmitting instruction information on a first channel transmission method to a reception end, and a step of transmitting the first channel to the reception end using a resource region are comprised, wherein the first channel is either an advanced-physical downlink control channel (A-PDCCH) or a relay-physical downlink control channel (R-PDCCH), the first channel is not transmitted when at least a portion of the resource region overlaps with a resource region used for transmitting a second channel, and wherein the second channel can be periodically transmitted using a predetermined portion of the resource region.

Claims

1. A method for receiving a signal by a terminal in a wireless communication system, the method comprising:

receiving, from a base station (BS), configuration information for a first channel; and

monitoring the first channel in a first resource region of a plurality of resource regions within a data region of a subframe according to the configuration information,

wherein the first channel is an Advanced-Physical Downlink Control Channel (A-PDCCH),

wherein the first resource region is a resource region within the data region of the subframe which does not overlap a second resource region within the data region of the subframe, the second resource region being used by the BS for transmitting a second channel to the terminal, and

wherein the second channel is periodically transmitted.

2. The method according to claim 1, wherein the second channel includes at least one of a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS), and a Physical Broadcast Channel (PBCH).

3. The method according to claim 1, wherein the configuration information is transmitted through RRC (radio resource control) signaling, MAC (medium access control) signaling, or physical (PHY) layer signaling.

4. The method according to claim 1, wherein each of the plurality of resource regions corresponds to a resource block (RB).

5. The method according to claim 1, wherein the BS is an evolved Node B (eNodeB) and the terminal is a user equipment (UE) or relay node (RN).

6. The method according to claim 1, further comprising:

receiving the first channel as a result of the monitoring.

7. A terminal configured to receive a signal in a wireless communication system, the method comprising:

a reception module configured to receive, from a base station (BS), configuration information for a first channel; and

a processor configured to monitor the first channel in a first resource region of a plurality of resource regions within a data region of a subframe according to the configuration information,

wherein the first channel is an Advanced-Physical Downlink Control Channel (A-PDCCH),

wherein the first resource region is a resource region within the data region of the subframe which does not overlap a second resource region within the data region of the subframe, the second resource region being used by the BS for transmitting a second channel to the terminal, and

wherein the second channel is periodically transmitted.

8. The terminal according to claim 7, wherein the second channel includes at least one of a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS), and a Physical Broadcast Channel (PBCH).

9. The terminal according to claim 7, wherein the configuration information is transmitted through RRC (radio resource control) signaling, MAC (medium access control) signaling, or physical (PHY) layer signaling.

10. The terminal according to claim 7, wherein each of the plurality of resource regions corresponds to a resource block (RB).

11. The terminal according to claim 7, wherein the BS is an evolved Node B (eNodeB) and the terminal is a user equipment (UE) or relay node (RN).

12. The terminal according to claim 7, wherein the processor is further configured to receive the first channel as a result of the monitoring.
