Abstract: A method of sending status information (STATUS PDU) in which a receiving side reports a data received state to a transmitting side in a mobile telecommunication system. A receiving side radio link control (RLC) entity considers an available radio resource to construct a status PDU fit to a size of the available radio resource and then sends the constructed status PDU to a transmitting side RLC entity, thereby avoiding a deadlock situation of RLC protocols.

Abstract: A method for transmitting downlink data to a mobile terminal is disclosed. The mobile terminal receives a particular common H-RNTI (HS-DSCH Radio Network Identifier) via an HS-SCCH (High Speed-Shared Control Channel) associated with an HS-DSCH (High Speed-Downlink Shared Channel), recognizes whether a header of a MAC (Medium Access Control) PDU (Packet Data Unit) transmitted by the HS-DSCH includes a terminal-exclusive identifier, acquires the terminal-exclusive identifier, and processes the MAC PDU as its own if the acquired terminal-exclusive identifier is intended for the terminal itself.

Abstract: An apparatus and method for performing procedures (protocols) of a PDCP (Packet Data Convergence Protocol) layer and an RLC (radio layer in an E-UMTS (Evolved Universal Mobile Telecommunications System) which has evolved from UMTS, among radio protocols of a mobile communication system. The PDCP layer performs ciphering on data (i.e., PDCP SDU) received from an upper layer, generates an indicator discriminating ciphered data and non-ciphered data (i.e., an ROHC feedback packet directly generated by the PDCP layer), and transmits the same to a lower layer (i.e., MAC layer). A PDCP SN (Sequence Number) is defined as an algorithm for ciphering the data in the PDCP layer to perform ciphering in the PDCP layer.

Abstract: In a wireless mobile communications system, a method for controlling a radio resource allocation is provided. A network transmits access control information to a terminal such that a request for the radio resource allocation which will be transmitted from the terminal can be controlled. The terminal selectively transmits the request for the radio resource allocation based on the received information, thus a transmission of an unnecessary request for the radio resource can be minimized, thereby preventing a waste of the radio resource.
