Abstract
Embodiments of the present disclosure relate to methods and apparatuses for path switch in a wireless communication system. According to some embodiments of the disclosure, a method may include: establishing, at a first user equipment (UE), a radio resource control (RRC) connection with abase station (BS) via a second UE, wherein a PC5 RRC connection between the first UE and the second UE has been established and an RRC connection between the second UE and the BS has been established; receiving an RRC reconfiguration message including a path switching indication from the BS, wherein the path switching indication indicates a switch to a target cell of the BS using a Uu interface; in response to the path switch indication, performing a random access (RA) with the BS; and in response to accessing a target cell, transmitting an RRC reconfiguration complete message to the BS. Furthermore, the second UE may receive an indication from the BS to release the first UE. The second UE may forward the buffered data from the first UE to the BS after receiving the release indication.
