1. A method of triggering a packet data convergence protocol (PDCP) status report performed by a user equipment (UE), the method comprising:
receiving, from a network, a Data Radio Bearer (DRB) configuration for configuring a DRB that is associated with a first PDCP entity of the UE;
receiving, from the network, a Multicast Broadcast Service Radio Bearer (MRB) configuration for configuring an MRB that is associated with a second PDCP entity of the UE;
triggering, by the first PDCP entity, a first PDCP status report based on a first configuration of the first PDCP entity;
receiving, from the network, an information element (IE) indicating that the second PDCP entity is configured to trigger a second PDCP status report; and
triggering, by the second PDCP entity, the second PDCP status report upon receiving, from the network, the IE and a first Radio Resource Control (RRC) reconfiguration message for a second configuration of the second PDCP entity, wherein:
the first RRC reconfiguration message is used for reconfiguring the second PDCP entity and indicates at least one of PDCP entity re-establishment and PDCP data recovery of the second PDCP entity.
