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 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).
