Dynamic subframe setting method for wireless communication system, and device for same

A user equipment in a wireless communication system, comprising:

• a wireless communication module configured to transmit and receive a signal to and from a base station;
• and
• a processor configured to:
• process the signal,
• control the wireless communication module to transmit an uplink signal in a first subframe and receive a downlink signal in a second subframe,
• control the wireless communication module to receive an indicator indicating a change of a usage of the first subframe to a downlink signal reception on a physical control channel from the base station, and
• control the wireless communication module to receive downlink signals in the first and second subframes, if the usage of the first subframe is changed to the downlink signal reception, and wherein:
• in the transmitting of the uplink signal in the first subframe and the receiving of the downlink signal in the second subframe, a guard period is interposed between the first and second subframes,
• in the receiving of the downlink signals in the first and second subframes, the guard period is positioned at a start of the first subframe and the first and second subframes are contiguous, and wherein, in the receiving of the downlink signals in the first and second subframes, the user equipment does not perform measurement for Radio Resource Management (RRM) in the first subframe.
