Abstract: A method of performing a random access channel (RACH) procedure between a mobile terminal and a network includes the steps of detecting whether a random access response (RAR) is received from the network within a certain time period, the RAR including information about a random access channel (RACH) preamble transmitted to the network; and if the RAR is not received within the certain time period or if the information about the transmitted RACH preamble included in the RAR does not match the transmitted RACH preamble, performing a first procedure to detect failures in the RACH procedure; and if the RAR is received within the certain time period and if the information about the transmitted RACH preamble included in the RAR matches the transmitted RACH preamble, performing a second procedure to detect failures in the RACH procedure.

Abstract: With respect to generating and sending a MAC PDU by using the radio resources allocated to the mobile terminal, the level of priority between the buffer status report (BSR) and the established logical channels are defined such that the data of each logical channel and buffer status report can be more effectively, efficiently and quickly transmitted.

Abstract: Disclosed is a radio (wireless) communication system providing a radio communication service and a terminal, and more particularly, to a method of delivering a continuously and/or consecutively received Packet Data Convergence Protocol (PDCP) Service Data units (SDUs) to an upper layer immediately if a PDCP entity receives the PDCP SDUs during a process of a RLC re-establishment within an Evolved Universal Mobile Telecommunications System (E-UMTS) that has evolved from a Universal Mobile Telecommunications System (UMTS) or a Long Term Evolution (LTE) system.

Abstract: A method of moving a receiving window in a wireless mobile communication system, wherein the AM RLC of the transmitting side sends information of the last discarded SDU regardless of continuity of the discarded SDUs. The AM RLC of the receiving side checks whether all SDUs from the start point of the receiving window up to the last discarded SDU are successfully received, delivers the SDUs that are successfully received to an upper layer, and discard only those SDUs that are not successfully received.

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.
