A logical channel data packet transmission method for a user equipment (UE) is provided. The UE includes a processor configured to perform the following instructions. A packet data control protocol (PDCP) packet data unit (PDU) is duplicated to generate a first PDCP PDU and a second PDCP PDU in a PDCP entity. The first PDCP PDU is transmitted to a first radio link control (RLC) bearer. The second PDCP PDU is transmitted to a second RLC bearer. A first RLC PDU is generated in response to the first PDCP PDU in the first RLC bearer. A second RLC PDU is generated in response to the PDCP PDU in the second RLC bearer. The first RLC PDU and the second RLC PDU are received in a medium access control (MAC) entity associated to the first and second RLC bearers.
