Abstract: An electronic device is disclosed. The electronic device supporting a low power wide area network (LPWAN) includes a communication circuit to make communication with a base station, a processor electrically connected with the communication circuit, and a memory electrically connected with the processor. The memory may include instructions that, when executed, cause the processor to establish a radio link with the base station by using the communication circuit, to transmit, to the base station, a first message requesting a random access by using the communication circuit, to receive a second message replying to the first message from the base station by using the communication circuit, when a timer is running for uplink transmission timing, and to update an existing timing advance value for the uplink transmission timing, based on a timing advance value included in the second message.
