Operation method of target relay ue associated with end-to-end bearer configuration in ue-to-ue relay in wireless communication system

A target remote User Equipment (UE) related to a UE-to-UE relay in a wireless communication system, the target remote UE comprising:

• at least one processor;
• and
• at least one computer memory operatively connected to the at least one processor and storing instructions enabling the at least one processor to perform operations when executed, the operations comprising:
• receiving a configuration related to an end-to-end bearer configuration from a source remote UE through a relay UE;
• and
• establishing an end-to-end connection with the source remote UE,
• wherein the configuration related to the end-to-end bearer configuration includes information related to an establishment of an SL connection between the relay UE and the source remote UE in connection with the end-to-end bearer configuration and
• wherein based on the information related to the establishment of the SL connection between the relay UE and the source remote UE and the configuration related to the end-to-end bearer configuration between the target remote UE and the source remote UE, the target remote UE establishes an SL connection with the relay UE.

A processing device in a wireless communication system, the processing device comprising:

• at least one processor;
• and
• at least one memory operatively connected to the at least one processor and storing at least one instruction enabling the at least one processor to perform operations when executed, the operations comprising:
• receiving a configuration related to an end-to-end bearer configuration from a source remote UE through a relay UE;
• and
• establishing an end-to-end connection with the source remote UE,
• wherein the configuration related to the end-to-end bearer configuration includes information related to an establishment of an SL connection between the relay UE and the source remote UE in connection with the end-to-end bearer configuration and
• wherein based on the information related to the establishment of the SL connection between the relay UE and the source remote UE and the configuration related to the end-to-end bearer configuration between the target remote UE and the source remote UE, the target remote UE establishes an SL connection with the relay UE.

A non-volatile computer-readable storage medium storing at least one computer program storing at least one computer program including an instruction enabling the at least one processor to perform operations for a relay UE when executed,

• the operations comprising:
• receiving a configuration related to an end-to-end bearer configuration from a source remote UE through a relay UE;
• and
• establishing an end-to-end connection with the source remote UE,
• wherein the configuration related to the end-to-end bearer configuration includes information related to an establishment of an SL connection between the relay UE and the source remote UE in connection with the end-to-end bearer configuration and
• wherein based on the information related to the establishment of the SL connection between the relay UE and the source remote UE and the configuration related to the end-to-end bearer configuration between the target remote UE and the source remote UE, the target remote UE establishes an SL connection with the relay UE.
