1. A method for a first UE (User Equipment) to report UE sidelink capability information to a network node, comprising:
establishing a unicast link with a second UE;
transmitting a first sidelink capability information of the first UE to the second UE over the unicast link established with the second UE after the unicast link has been established, wherein the first sidelink capability information includes a first parameter of a first Radio Link Control (RLC) configuration supported by the first UE;
receiving a second sidelink capability information of the second UE from the second UE over the unicast link established with the second UE after the unicast link has been established, wherein the second sidelink capability information includes a second parameter of a second RLC configuration supported by the second UE;
transmitting the first sidelink capability information including the first parameter of the first RLC configuration supported by the first UE and the second sidelink capability information including the second parameter of the second RLC configuration supported by the second UE to the network node;
receiving a second message from the network node, wherein the second message includes a SLRB (Sidelink Radio Bearer) configuration used for sidelink communication with the second UE and the SLRB configuration includes RLC parameters used on a SLRB; and
transmitting an Access Stratum (AS) configuration including the RLC parameters used on the SLRB to the second UE and establishing the SLRB for sidelink transmission from the first UE to the second UE based on the RLC parameters used on the SLRB.
