1. A method for a UE-to-UE relay, comprising:
the UE-to-UE relay establishes a first PC5 Radio Resource Control (RRC) connection with a first remote User Equipment (UE) and establishes a second PC5 RRC connection with a second remote UE to support communication between the first remote UE and the second remote UE via the UE-to-UE relay;
the UE-to-UE relay transmits a Sidelink UE Information message to a network node to request sidelink transmission resource, wherein the Sidelink UE Information message includes an identity (ID) of the first remote UE, a destination ID of the second remote UE, and an ID of a Sidelink (SL) Data Radio Bearer (DRB); and
the UE-to-UE relay receives a RRC Reconfiguration message from the network node, wherein the RRC Reconfiguration message includes the ID of the first remote UE, the ID of the SL DRB, and a configuration of a second PC5 Radio Link Control (RLC) channel.
