Abstract: A mobile terminal performs a random access procedure with a network that includes transmitting to the network a random access preamble directly allocated to the mobile terminal by the network and receiving a random access response from the network in response to transmission of the random access preamble. The terminal performs a discontinuous reception (DRX) operation that controls how the mobile terminal monitors a physical downlink control channel (PDCCH).

Abstract: A random access channel (RACH) procedure includes a mobile terminal receiving from a network a message that indicates a RACH preamble for the mobile terminal. The terminal transmits the RACH preamble to the network and then receives a RACH response from the network. The terminal monitors a downlink channel according to a discontinuous reception (DRX) active time for radio resource allocation information for a data transmission by the terminal. The DRX active time specifies a time until the radio resource allocation information for the data transmission is indicated.

Abstract: A random access procedure between a mobile terminal and a network is performed based upon the characteristics of a RACH preamble transmitted by the terminal. A first type of random access preamble is selectable by the terminal from a set of random access preambles, and a second type of random access preamble is directly allocated to the terminal by the network. The network responds with a random access response. The terminal performs a discontinuous reception (DRX) operation that allows it to monitor a downlink control channel discontinuously. The DRX operation includes an active time period during which the terminal monitors the control channel after successful reception of the random access response for the second type of random access preamble until a transmission from the network addressed to a Cell-Radio Network Temporary Identifier (C-RNTI) associated with the terminal is 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.

Abstract: A status report transmission of the PDCP layer for a PDCP status report can reduce radio resources by transmitting the reception success or failure of a series of PDCP service data units (SDUs) in the form of a bitmap when configuring the PDCP status report for reporting a reception status of PDCP SDUs to another party in the PDCP layer. A PDCP control packet data unit (PDU) is generated to communicate a status report for one or more PDCP SDUs transmitted from a transmitting node. The PDCP control PDU includes a data/control (D/C) bit field to indicate the PDCP control PDU is a control PDU, a control PDU type field to indicate a type of corresponding control information, a sequence number field to indicate a first missing PDCP SDU, and a bitmap field for a variable length bitmap. A specific bit in the variable length bitmap indicates whether a corresponding one of the one or more PDCP SDUs has been successfully been received. The PDCP control PDU is transmitted to the transmitting node.
