Method for transmitting signal using plurality of antenna ports and transmission end apparatus for same
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.
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;
monitoring the first channel in a first resource region which does not overlap a second resource region of a plurality of resource regions within a data region of a subframe according to the configuration information, and
receiving a downlink data channel corresponding to the first channel,
wherein the second resource region is used by the BS for transmitting a second channel to the terminal,
wherein the second channel is periodically transmitted, and
wherein each of the plurality of resource regions corresponds to a resource block (RB).
2. The method according to claim 1 , wherein the first channel includes a physical downlink control channel (PDCCH).
3. 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).
4. The method according to claim 1 , wherein the configuration information is transmitted through radio resource control (RRC) signaling, medium access control (MAC) signaling, or physical (PHY) layer signaling.
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 terminal comprising:
a receiver; and
a processor that controls the receiver;
wherein the processor receives, from a base station (BS), configuration information for a first channel, monitors the first channel in a first resource region which does not overlap a second resource region of a plurality of resource regions within a data region of a subframe according to the configuration information, and receives a downlink data channel corresponding to the first channel,
wherein the second resource region is used by the BS for transmitting a second channel to the terminal,
wherein the second channel is periodically transmitted, and
wherein each of the plurality of resource regions corresponds to a resource block (RB).
8. The terminal according to claim 7 , wherein the first channel includes a physical downlink control channel (PDCCH).
9. 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).
10. The terminal according to claim 7 , wherein the configuration information is transmitted through radio resource control (RRC) signaling, medium access control (MAC) signaling, or physical (PHY) layer signaling.
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 further receives the first channel as a result of the monitoring.
