1. A method of transmitting uplink data using a preconfigured uplink resource (PUR) in a wireless communication system, the method performed by a terminal and 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.
