The present invention provides an apparatus and method for MBS reception with duplicate data packets. In an example, a UE establishes a protocol stack with a PTM branch and a PTP branch, receives duplicate data packets from the PTM branch and the PTP branch, and processes the duplicate data packets from the PTM and PTP branches at a duplicate protocol layer. The MBS data packets are duplicated at a corresponding duplicate protocol layer of a network node. The UE duplicate protocol layer may be a PDCP layer, an RLC layer, or a PHY layer. When the RLC SN is different in PTM, the RLC layer includes a PTM RLC entity and a PTP RLC entity. The UE duplicate protocol layer merges received data packets and / or discards duplicate data packets from the PTM branch and the PTP branch. By utilizing the present invention, MBS transmission and reception can be performed reliably.
