Abstract
The present invention relates to a wireless communication system. More specifically, a method for enabling a terminal to receive control information in a wireless communications system according to the present invention includes the steps of: constituting PCell and SCell; and monitoring a plurality of expected channels in a search space to receive the control information from a sub-frame #n in SCell, wherein if the sub-frame #n is included in a particular sub-frame set, the search space includes CSS, or if the sub-frame #n is not included in the particular sub-frame set, the search space includes only USS.
Claims10
A method for receiving, by a User Equipment (UE), control information in a wireless communication system, comprising:
- configuring a primary cell (PCell) and a secondary cell (SCell);
- and monitoring a plurality of control channel candidates within a search space for receiving the control information in subframe #n in the SCell,
- wherein, when the subframe #n is included in a specific subframe set, the search space includes a common search space (CSS) of the SCell, and a process of monitoring control channel candidates with a downlink control information (DCI) format 1C is skipped from a CSS of the PCell in subframe #n,
- wherein, when the subframe #n is not included in the specific subframe set, the search space includes only a user-specific search space (USS),
- wherein the DCI format 1C is used for Physical Downlink Shared Channel (PDSCH) compact scheduling or Multimedia Control Channel (MCCH) change notification.
A User Equipment (UE) configured to receive control information in a wireless communication system, comprising:
- a radio frequency (RF) unit;
- and a processor,
- wherein the processor is configured to configure a primary cell (PCell) and a secondary cell (SCell) and to monitor a plurality of control channel candidates within a search space for receiving the control information in subframe #n in the SCell,
- wherein, when the subframe #n is included in a specific subframe set, the search space includes a common search space (CSS) of the SCell, and a process of monitoring control channel candidates with a downlink control information (DCI) format 1C is skipped from a CSS of the PCell in subframe #n,
- wherein, when the subframe #n is not included in the specific subframe set, the search space includes only a user-specific search space (USS),
- wherein the DCI format 1C is used for Physical Downlink Shared Channel (PDSCH) compact scheduling or Multimedia Control Channel (MCCH) change notification.
