1. A method comprising:
establishing, by a user equipment (UE), an indirect connection with a source gNB through a sidelink relay path in a new radio (NR) wireless network, wherein the sidelink relay path has at least one serving relay UE connecting with the UE through a serving sidelink;
receiving a measurement configuration including a frequency list for measurement from the source gNB, wherein the frequency list including a list of one or more Uu direct links and one or more PC5 sidelinks;
sending a measurement report upon detecting a predefined path switching triggering event based on the received measurement configuration;
receiving a path switching message from the source gNB indicating to switch from the sidelink relay path to a target direct Uu link; and
performing a path switching with service continuity by establishing a connection with the target direct Uu link based on the path switching message.
