Abstract: In a wireless communication system, a user equipment, already configured with a first medium access control (MAC) entity for a master cell group (MCG) associated with a master base station, capable of configuring a secondary cell group (SCG) associated with a secondary base station based on a radio resource control (RRC) message received from the master base station. The user equipment can configure a second MAC entity for the newly configured SCG. Through a second RRC message from the master base station, the user equipment can then add a new SCG cell to the SCG, where the second MAC entity is commonly configured for one or more secondary SCG cells belonging to the SCG.

Abstract: In the present invention, the transmitting device attaches a sequence number (SN) for each of service data unit (SDU) elements to generate a protocol data unit (PDU) containing the SDU elements. Each of the SDU elements is a SDU or SDU segment. The PDU includes the SDU elements and respective SNs for the SDU elements. The PDU includes an indicator for each of the SDU elements, and the indicator indicating whether a corresponding SDU element is a SDU or SDU segment.
