Method and device for multi-hop sidelink communication in shared cot

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

• receiving sharing information from a second UE;
• receiving first sidelink (SL) transmission from a third UE within a channel occupancy time (COT) that is shared based on the sharing information;
• and
• transmitting a second SL transmission in the COT based on the sharing information,
• wherein the sharing information includes at least one of a source identifier (ID), a destination ID, a remaining COT duration, frequency domain information of a resource block (RB) set(s) of a COT, a channel access priority class (CAPC), an additional ID, or an associated cast type.

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

• at least one processor,
• wherein the at least one processor causes the first UE to:
• receive occupancy time (COT) sharing information from a second UE;
• receive first sidelink (SL) transmission for a third UE within a channel occupancy time (COT) that is shared based on the sharing information;
• transmit a second SL transmission in the COT based on the sharing information,
• wherein the sharing information includes at least one of a source identifier (ID), a destination ID, a remaining COT duration, frequency domain information of a resource block (RB) set(s) of a COT, a channel access priority class (CAPC), an additional ID, or an associated cast type.
