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 transmitting a signal by a base station (BS) in a wireless communication system, the method comprising:

transmitting configuration information for a first channel to a terminal; and

transmitting the first channel to the terminal 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 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,

wherein the first channel is an Advanced-Physical Downlink Control Channel (A-PDCCH), 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), or a Broadcast Channel (BCH).

3. The method according to claim 1, wherein the indication information is transmitted through RRC signaling, MAC layer signaling, or physical (PHY) layer signaling.

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

5. The method according to claim 1, wherein the first channel is transmitted in a subframe except a subframe in which the second channel is transmitted.

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

7. A base station (BS) for transmitting a signal in a wireless communication system, comprising:

a transmitter; and

a processor operatively connected to the transmitter and configured to

transmit configuration information for a first channel to a terminal, and

transmit the first channel to the terminal 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 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,

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

wherein the second channel is periodically transmitted.

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

9. The BS according to claim 7, wherein the first channel is transmitted in a subframe except a subframe in which the second channel is transmitted.

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