Abstract: An operation method of a first terminal may comprise: configuring a Uu access link with a base station, and receiving a first message from the base station, the first message including a relay RNTI for identifying the first terminal, a node address of the base station, and a RAP entity ID for identifying a RAP entity configured for the first terminal; configuring a relay link with a second terminal when communication with the base station is disconnected; requesting link switching by transmitting to the base station a second message via the second terminal, the second message including the relay RNTI, node address, and RAP entity ID; and receiving a response to the second message from the base station via the second terminal, and switching a link with the base station from the Uu access link to the relay link.

Abstract: An operation method of a first terminal in a communication system may comprise: receiving a link establishment request message from a second terminal; transmitting, to the second terminal, a link establishment response message including a node address of a first base station in response to the link establishment request message; and receiving a link establishment completion message from the second terminal.

Abstract: An operation method of a first communication node connected to a first hub in a communication network may comprise measuring signal qualities for a first radio signal received from the first hub and a second radio signal received from a second hub adjacent to the first hub; calculating a difference in the signal qualities for the first radio signal and the second radio signal; comparing the calculated difference with a plurality of predetermined threshold values for handover of the first communication node; and performing a handover-related procedure indicated by one of the plurality of predetermined threshold values based on a result of the comparison.

Abstract: Disclosed is a method for transmitting data between a terminal and a base station. The method includes: being assigned a scheduling request identifier (SRID) through a connection with the base station, in the terminal; configuring a scheduling request (SR) message and transmitting the scheduling request message to the base station when uplink traffic is generated, in the terminal; assigning an uplink resource based on the scheduling request message, in the base station; and transmitting data using the uplink resource, in the terminal.
