A method and apparatus for small data transmission without a path switch procedure in a wireless communication system is provided. A new gNB, which is a radio access network (RAN) node to which a wireless device attempts a connection resume procedure while in an inactive state, receives an anchor kept indication and/or a small data indication from a last serving gNB. The anchor kept indication indicates that the last serving gNB keeps a user equipment (UE) context and/or a UE-associated NG connection with the core network. The small data indication indicates not relocating a UE context from the last serving gNB to the new gNB.
