Method and apparatus for transceiving control information in a wireless communication system
An embodiment of the present invention relates to a method in which a terminal receives control information in a wireless communication system, said method comprising: a step of performing blind decoding in at least one portion of a resource region except the time unit indicated by a physical control format indicator channel (PCFICH) on a subframe, said at least one portion of the resource region is determined by whether a synchronizing signal or system information is transmitted or not.
1. A method for receiving control information of a user equipment (UE) in a wireless communication system, the method comprising:
performing blind decoding for the control information in a part of a first resource region other than a time unit indicated by a physical control format indicator channel (PCFICH) on a subframe,
wherein the part of the first resource region is decided according to whether or not a synchronous signal or system information is transmitted,
wherein if the subframe is used as a specific subframe on which at least one of the synchronous signal or the system information is transmitted, a frequency domain on which the synchronous signal or the system information is transmitted is not contained in the part of the first resource region.
2. The method according to claim 1 , wherein the synchronous signal includes a primary synchronous signal and a secondary synchronous signal, and the system information is transmitted on a physical broadcast channel (PBCH).
3. The method according to claim 1 , wherein the frequency domain corresponds to 6 resource blocks (6 RBs) located at a center part of an entire frequency bandwidth.
4. The method according to claim 1 , wherein a second resource region on which a reference signal is transmitted is not contained in the part of the first resource region.
5. The method according to claim 4 , wherein the reference signal (RS) is any one of a cell-specific reference signal (RS) or channel status information reference signal (CSI-RS).
6. A method for transmitting control information of a base station (BS) in a wireless communication system, the method comprising:
transmitting downlink control information in a part of a first resource region other than a time unit indicated by a physical control format indicator channel (PCFICH) on a subframe,
wherein the part of the first resource region is decided according to whether or not a synchronous signal or system information is transmitted,
wherein if the subframe is used as a specific subframe on which at least one of the synchronous signal or the system information is transmitted, a frequency domain on which the synchronous signal or the system information is transmitted is not contained in the part of the first resource region.
7. The method according to claim 6 , wherein the synchronous signal includes a primary synchronous signal and a secondary synchronous signal, and the system information is transmitted on a physical broadcast channel (PBCH).
8. The method according to claim 6 , wherein the frequency domain corresponds to 6 resource blocks (6 RBs) located at a center part of an entire frequency bandwidth.
9. The method according to claim 6 , wherein a second resource region on which a reference signal is transmitted is not contained in the part of the first resource region.
10. The method according to claim 9 , wherein the reference signal (RS) is any one of a cell-specific reference signal (RS) or channel status information reference signal (CSI-RS).
11. A user equipment (UE) device for use in a wireless communication system comprising:
a transmission (Tx) module; and
a processor,
wherein the processor performs blind decoding for a control information in a part of a first resource region other than a time unit indicated by a physical control format indicator channel (PCFICH) on a subframe,
wherein the part of the first resource region is decided according to whether or not a synchronous signal or system information is transmitted,
wherein if the subframe is used as a specific subframe on which at least one of the synchronous signal or the system information is transmitted, a frequency domain on which the synchronous signal or the system information is transmitted is not contained in the part of the first resource region.
12. A base station (BS) device for use in a wireless communication system comprising:
a reception (Rx) module; and
a processor,
wherein the processor transmits downlink control information in a part of a first resource region other than a time unit indicated by a physical control format indicator channel (PCFICH) on a subframe,
wherein the part of the first resource region is decided according to whether or not a synchronous signal or system information is transmitted,
wherein if the subframe is used as a specific subframe on which at least one of the synchronous signal or the system information is transmitted, a frequency domain on which the synchronous signal or the system information is transmitted is not contained in the part of the first resource region.
