Method for transmitting and receiving uplink data by using PUR in wireless communication system, and device for same

A terminal configured to transmit uplink data using a preconfigured uplink resource (PUR) in a wireless communication system, the terminal comprising:

• a transmitter configured to transmit a radio signal;
• a receiver configured to receive a radio signal;
• and
• a processor configured to perform operations comprising:
• receiving in a radio resource control (RRC) connected state, from a base station, configuration information for transmitting the uplink data using the PUR in an RRC idle state, wherein the configuration information includes first information regarding a timing advance (TA) validity timer and second information regarding a reference signal received power (RSRP) level;
• transitioning from the RRC connected state to the RRC idle state;
• and
• transmitting, to the base station, the uplink data using the PUR based on the configuration information in the RRC idle state,
• wherein, based on i) the TA validity timer not being expired and ii) a RSRP measurement value being greater than or equal to the RSRP level, a TA for transmitting the uplink data using the PUR is determined to be valid, and
• wherein there is only one hybrid automatic repeat request (HARQ) process for transmitting the uplink data using the PUR.
