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 SDUs in the form of a bitmap when configuring the PDCP status report for reporting a reception status of the PDCP SDU to another party in the PDCP layer in the LTE system.

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 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 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 translation: 基于RACH前导码的特性，执行移动终端和网络之间的随机接入过程。 如果RACH前导码被网络明确地通知，则监视下行链路信道，直到根据从网络接收到的无线电资源分配信息来指示新的传输。 如果RACH前导码没有被网络明确发出信号，则启动争用解决定时器，并监视下行链路信道直到争用解决定时器到期。 以更有效的方式监视下行链路信道，导致功率消耗的有效降低。
