1. In a wireless communication system that employs a layered radio interface protocol, an apparatus comprising:
- a radio resource control (RRC) layer;
a medium access control (MAC) layer; and
a radio link control (RLC) layer comprising at least three data transmission mode entities, the at least three data transmission mode entities including;
a transparent mode RLC entity adapted to control the transmission of data units between the RRC layer and the MAC layer by segmenting and reassembling data units that have no headers;
an unacknowledged mode RLC entity adapted to control the transmission of data units between the RRC layer and the MAC layer by framing and deframing data units and detect and discard data units that contain an error; and
an acknowledged mode RLC entity adapted to control the flow of data units between the RRC layer and the MAC layer by framing and deframing data units and by error correction.

Abstract
Radio protocol for a next generation mobile communication system is disclosed including a radio link control layer for connecting to an upper layer through a service access point provided in advance and for connecting to a lower layer through a plurality of logic channels provided in advance. The radio link control layer includes at least one radio link control entity for transmission/reception of data to/from up-link or down-link according to a form of a data transmission mode.

13. In a wireless communication system that employs a layered radio interface protocol that includes a radio resource control (RRC) layer, a medium access control (MAC) layer, a radio link control (RLC) layer, a method of transferring data units from the RRC layer to the MAC layer, the method comprising:
-
receiving a service data unit from the RRC layer at one of at least three transmission mode entities in the RLC layer; processing the service data unit, where processing includes one of; segmenting the service data unit into a plurality of protocol data units, using a transparent mode RLC (RLC-T) entity if the service data unit has no header, segmenting the service data unit into a plurality of protocol data units and framing the protocol data units, using an unacknowledged mode RLC (RLC-UNACK) entity, and segmenting the service data unit into a plurality of protocol data, framing the protocol data units and correcting a protocol data unit that contains an error, using an acknowledged mode RLC (RLC-ACK) entity, and; transferring a plurality of protocol data units from the one transmission mode entity in the RLC layer to the MAC layer through one of a plurality of service access points associate with the MAC layer. - View Dependent Claims (14, 15, 16, 17, 18, 19)
