Method and device for allocating resource for sidelink signal in wireless communication system

A base station in a wireless communication system, the base station comprising:

• at least one processor;
• and
• at least one computer memory operably connected to the at least one processor and configured to store instructions that, when executed, cause the at least one processor to perform operations comprising:
• transmitting a signal for allocating resources for a sidelink signal to a first user equipment (UE);
• receiving information on a number of one or more pieces of hybrid automatic repeat request (HARQ) non-acknowledgement (NACK) feedback for the sidelink signal from the first UE;
• and
• transmitting information for allocating resources for a next sidelink signal to the first UE,
• wherein a number of the resources for the next sidelink signal is determined based on the information on the number of the one or more pieces of HARQ NACK feedback for the sidelink signal.

A computer-readable storage medium configured to store at least one computer program including instructions that, when executed by at least one processor, cause the at least one processor to perform operations for a user equipment (UE), the operations comprising:

• transmitting a signal for allocating resources for a sidelink signal to a first user equipment (UE);
• receiving information on a number of one or more pieces of hybrid automatic repeat request (HARQ) non-acknowledgement (NACK) feedback for the sidelink signal from the first UE;
• and
• transmitting information for allocating resources for a next sidelink signal to the first UE,
• wherein a number of the resources for the next sidelink signal is determined based on the information on the number of the one or more pieces of HARQ NACK feedback for the sidelink signal.

A method of transmitting a signal by a first user equipment (UE) in a wireless communication system, the method comprising:

• transmitting a sidelink signal to a second UE;
• receiving one or more pieces of hybrid automatic repeat request (HARQ) non-acknowledgement (NACK) feedback for the sidelink signal from the second UE;
• transmitting information on a number of the one or more pieces of HARQ NACK feedback to a base station;
• and
• receiving information for allocating resources for a next sidelink signal from the base station,
• wherein a number of the resources for the next sidelink signal is determined based on the information on the number of the one or more pieces of HARQ NACK feedback.

A first user equipment (UE) in a wireless communication system, the first UE comprising:

• at least one processor;
• and
• at least one computer memory operably connected to the at least one processor and configured to store instructions that, when executed, cause the at least one processor to perform operations comprising:
• transmitting a sidelink signal to a second UE;
• receiving one or more pieces of hybrid automatic repeat request (HARQ) non-acknowledgement (NACK) feedback for the sidelink signal from the second UE;
• transmitting information on a number of the one or more pieces of HARQ NACK feedback to a base station;
• and
• receiving information for allocating resources for a next sidelink signal from the base station,
• wherein a number of the resources for the next sidelink signal is determined based on the information on the number of the one or more pieces of HARQ NACK feedback.
