Abstract
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.
Claims8
A method for receiving control information through an enhanced physical downlink control channel (EPDCCH), by a user equipment (UE) in a wireless communication system, the method comprising:
- performing blind decoding of a resource region comprising one or more EPDCCH candidates;
- and
- receiving control information through the one or more EPDCCH candidates,
- wherein the resource region is determined according to whether a primary synchronization signal (PSS), a secondary synchronization signal (SSS) or a physical broadcast channel (PBCH) is transmitted in a subframe,
- wherein when the PSS, the SSS, and the PBCH are all transmitted in the subframe, the resource region is determined as a first resource region excluding 6resource blocks (RBs) from subframes that are located at a center part of a first slot and a second slot of the subframe, and
- wherein when the PSS and the SSS are transmitted in the subframe and the PBCH is not transmitted in the subframe, the resource region is determined as a second resource region excluding 6 RBs from the subframes that are located at a center part of the first slot of the subframe.
A method for transmitting control information through an enhanced physical downlink control channel (EPDCCH), by a base station (BS) in a wireless communication system, the method comprising:
- transmitting control information through a resource region comprising one or more EPDCCH candidates,
- wherein the resource region is determined according to whether a primary synchronization signal (PSS), a secondary synchronization signal (SSS) or a physical broadcast channel (PBCH) is transmitted in a subframe,
- wherein when the PSS, the SSS, and the PBCH are all transmitted in the subframe, the resource region is determined as a first resource region excluding 6resource blocks (RBs) from subframes that are located at a center part of a first slot and a second slot of the subframe, and
- wherein when the PSS and the SSS are transmitted in the subframe and the PBCH is not transmitted in the subframe, the resource region is determined as a second resource region excluding 6 RBs from the subframes that are located at a center part of the first slot of the subframe.
A user equipment (UE) device operating in a wireless communication system, the UE comprising:
- a reception module configured to receive information;
- and
- a processor configured to:
- perform blind decoding of a resource region comprising one or more enhanced physical downlink control channel (EPDCCH) candidates;
- and
- control the reception module to receive control information through the one or more EPDCCH candidates,
- wherein the resource region is determined according to whether a primary synchronization signal (PSS), a secondary synchronization signal (SSS) or a physical broadcast channel (PBCH) is transmitted in a subframe,
- wherein when the PSS, the SSS, and the PBCH are all transmitted in the subframe, the resource region is determined as a first resource region excluding 6resource blocks (RBs) from the subframes that are located at a center part of a first slot and a second slot of the subframe, and
- wherein when the PSS and the SSS are transmitted in the subframe and the PBCH is not transmitted in the subframe, the resource region is determined as a second resource region excluding 6 RBs from the subframes that are located at a center part of the first slot of the subframe.
A base station (BS) operating in a wireless communication system, the BS comprising:
- a transmission module configured to transmit information;
- and
- a processor configured to control the transmission module to transmit control information through a resource region comprising one or more enhanced physical downlink control channel (EPDCCH) candidates,
- wherein the resource region is determined according to whether a primary synchronization signal (PSS), a secondary synchronization signal (SSS) or a physical broadcast channel (PBCH) is transmitted in a subframe,
- wherein when the PSS, the SSS, and the PBCH are all transmitted in the subframe, the resource region is determined as a first resource region excluding 6resource blocks (RBs) from subframes that are located at a center part of a first slot and a second slot of the subframe, and
- wherein when the PSS and the SSS are transmitted in the subframe and the PBCH is not transmitted in the subframe, the resource region is determined as a second resource region excluding 6 RBs from the subframes that are located at a center part of the first slot of the subframe.
