Abstract: Disclosed are methods for service discovery in a wireless personal area communication network. A method for service discovery, performed in a terminal, the method comprises performing a passive scan for searching a specific service based on whether to receive a frame including a specific service identifier; and, when it fails to search the specific service, performing an active scan which broadcasts a service discovery request command frame for searching the specific service. Thus, service discovery may be efficiently performed by reducing the operation complexity of the terminal and minimizing the power consumption of the terminal needed for service discovery, without support of a upper layer.

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.
