Abstract: Disclosed are methods and apparatuses for relaying messages in LPWAN. An operation method of a terminal may comprise transmitting a first join request message to a base station without IQ inversion; when a number of failed transmissions of the first join request message is greater than or equal to a preconfigured threshold, transmitting an IQ-inverted second join request message to a relay; and receiving a join response message from the relay that is a response to the second join request message. Accordingly, the performance of the communication system can be improved.
