Method and device for performing LTE sidelink transmission on basis of timing offset in NR V2X

A first device configured to perform sidelink communication, the first device comprising:

• at least one memory storing instructions;
• at least one transceiver;
• and
• at least one processor connected to the at least one memory and the at least one transceiver, wherein the at least one processor executes the instructions to:
• transmit, to a base station, user equipment (UE) capability information of the first device, wherein the UE capability information includes a first timing offset related to a minimum delay;
• receive, from the base station, a radio resource control (RRC) message related to the UE capability information, wherein the RRC message includes first timing offset candidate values related to Long Term Evolution (LTE) sidelink transmission;
• and
• perform the LTE sidelink transmission to a second device, based on the first timing offset candidate values which are configured by the RRC message.

An apparatus configured to control a first user equipment (UE), the apparatus comprising:

• at least one processor;
• and
• at least one memory connected to the at least one processor and storing instructions, wherein the at least one processor executes the instructions to:
• transmit, to a base station, UE capability information of the first UE, wherein the UE capability information includes a first timing offset related to a minimum delay;
• receive, from the base station, a radio resource control (RRC) message related to the UE capability information, wherein the RRC message includes first timing offset candidate values related to Long Term Evolution (LTE) sidelink transmission;
• and
• perform the LTE sidelink transmission to a second UE, based on the first timing offset candidate values which are configured by the RRC message.
