Method for transmitting signal using plurality of antenna ports and transmission end apparatus for same

Abstract

A method for transmitting a signal by using a plurality of antenna ports and a transmission end apparatus for same are disclosed. A method for a transmission end, which supports signal transmission through the plurality of antenna ports, transmitting the signal using the plurality of antenna ports, according to the present invention, comprises the following steps: transmitting a control channel to a reception end through a first antenna using a first resource domain; and transmitting a data channel to the reception end through the plurality of antenna ports including first antenna port using a second resource domain, wherein the second resource domain and the first resource domain have identical time domains but different frequency domains, and wherein from the time and frequency domains that belong to the first resource domain, the data channel is not transmitted through at least one antenna port from the antenna ports excluding the first antenna port.

1 . A method for receiving signals using a plurality of antenna ports by a reception end in a wireless communication system, the method comprising:
 receiving a control channel, by the reception end, through only a first antenna port among the plurality of antenna ports in a first slot of a first resource region having a respective first and second slot from a transmission end, wherein the control channel indicates a second resource region to be used for transmission of data channel, the second resource region having a respective first and second slot; and   receiving the data channel, by the reception end, through the plurality of antenna port,   wherein, when a portion of the second resource region is overlapped with the first resource region, the reception end receives only the control channel through the first antenna in the first slot of the first resource region.   
     
     
         2 . The method according to  claim 1 , wherein the control channel is an Advanced-Physical Downlink Control Channel (A-PDCCH) or a Relay Physical Downlink Control Channel (R-PDCCH), and the data channel is a Physical Downlink Shared Channel (PDS CH). 
     
     
         3 . The method according to  claim 2 , wherein the transmission end is a base station (BS) and the reception end is a user equipment (UE) or a relay node (RN). 
     
     
         4 . The method according to  claim 1 , wherein:
 an antenna port index of the first antenna port is set to 7, and an antenna port indexes of the plurality of the antenna ports include 7, 8, 9 and 10.   
     
     
         5 . The method according to  claim 1 , wherein the first resource region corresponds to a Resource Block (RB) pair and the second resource region corresponds to at least one RB pair. 
     
     
         6 . The method according to  claim 1 , wherein the data channel is transmitted though the plurality of antenna ports in the second slot of the first resource region and in a first slot and a second slot of a region which is not overlapped with the first resource region within the second region. 
     
     
         7 . A reception end for receiving signals using a plurality of antenna ports in a wireless communication system, the reception end comprising:
 a receiver configured to: receive a control channel, by the reception end, through only a first antenna port among the plurality of antenna ports in a first slot of a first resource region having a respective first and second slot from a transmission end, wherein the control channel indicates a second resource region to be used for transmission of a data channel, the second resource region having a respective first and second slot, and   receive the data channel, by the reception end, through the plurality of antenna port,   wherein, when a portion of the second resource region is overlapped with the first resource region, the reception end receives only the control channel through the first antenna in the first slot of the first resource region.   
     
     
         8 . The reception end according  claim 7 , wherein the control channel is an Advanced-Physical Downlink Control Channel (A-PDCCH) or a Relay Physical Downlink Control Channel (R-PDCCH), and the data channel is a Physical Downlink Shared Channel (PDSCH). 
     
     
         9 . The reception end according  claim 8 , wherein the transmission end is a base station (BS) and the reception end is a user equipment (UE) or a relay node (RN). 
     
     
         10 . The reception end according  claim 7 , wherein:
 an antenna port index of the first antenna port is set to 7, and an antenna port indexes of the plurality of the antenna ports include 7, 8, 9 and 10.   
     
     
         11 . The reception end according  claim 7 , wherein the first resource region corresponds to a Resource Block (RB) pair and the second resource region corresponds to at least one RB pair. 
     
     
         12 . The reception end according to  claim 7 , wherein the data channel is transmitted though the plurality of antenna ports in the second slot of the first resource region and in a first slot and a second slot of a region which is not overlapped with the first resource region within the second region.
