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: 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). The DRX operation employs an active time in which the mobile terminal monitors the PDCCH, and the active time includes a time while: (i) an on-duration timer or a DRX Inactivity timer or a DRX retransmission timer or a contention resolution timer is operating, (ii) a scheduling request procedure is pending, (iii) an uplink grant for a retransmission can occur, or (iv) the PDCCH indicating a new transmission addressed to a Cell-Radio Network Temporary Identifier (C-RNTI) of the mobile terminal has not yet been received after successful reception of the random access response.

Abstract: A random access procedure between a mobile terminal and a network is performed based upon the characteristics of a RACH preamble. If the RACH preamble was explicitly signaled by the network, a downlink channel is monitored until a new transmission is indicated according to radio resource allocation information received from the network. If the RACH preamble was not explicitly signaled by the network, a contention resolution timer is started and the downlink channel is monitored until the contention resolution timer expires. Such monitoring of downlink channels in a more efficient manner, results in effective reduction in power consumption.

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.
