The present disclosure provides a method of a terminal supporting a multicast/broadcast service (MBS) in a wireless communication system. The method may comprise the steps of: receiving, from a base station, a radio resource control (RRC) message indicating to switch from a multicast service (point-to-multicast (PTM)) to a unicast service (point-to-point (PTP)); and initializing at least one window parameter on the basis of received packet data convergence protocol (PDCP) data.
