摘要:
Disclosed is a method for maintaining uplink timing synchronization by a User Equipment (UE) in a mobile communication system, without uplink transmission of a preamble from a UE or without transmission of uplink timing difference information from an Evolved Node B (E-NB) to solve the inefficient use problem of radio resources, occurring due to periodic transmission of uplink signaling and downlink signaling during maintenance of the uplink timing synchronization, and a UE apparatus for the same.

摘要:
A method and apparatus for transmitting a packet in a mobile communication system. A transmitting side allocates a short sequence number for an initial transmission packet using some bits among bits of a predetermined length for expressing a sequence number of the packet, and sets a first flag indicating use of the short sequence number. The transmitting side inserts the short sequence number and the first flag into the packet, and transmits the packet to a receiving side.
摘要:
A method for performing a Discontinuous Reception (DRX) operation by a connected mode User Equipment (UE) in a mobile communication system. The method includes waking up at a wake-up timing, and determining whether an incoming data indication is received from a Node B; reestablishing uplink synchronization upon receipt of the incoming data indication; and waking up after sleeping for a time from the incoming data indication reception timing, receiving a transmission resource allocation message from the Node B, and receiving downlink data over allocated transmission resources.
摘要:
A method for controlling a rate of a voice service in a mobile communication system supporting the voice service via a packet network. The method includes the steps of receiving a control message at a terminal from a radio network controller (RNC); if the control message indicates control of a downlink rate, determining a downlink rate according to the control message; setting a Change Mode Request (CMR) field of an uplink Voice over Internet Protocol (VoIP) packet according to the downlink rate, and transmitting the uplink VoIP packet from the terminal to the RNC; if the received control message indicates control of an uplink rate, determining an uplink rate according to the control message; and generating an uplink VoIP packet including uplink voice data generated according to the determined uplink rate and frame type (FT) information indicating the determined uplink rate, and transmitting the uplink VoIP packet from the terminal to the RNC.
摘要:
Disclosed is an apparatus and a method for radio connection setup in a mobile communication system. In the method, a UE reports mobility information to a network, and the network performs according to the mobility information of the UE. Therefore, it is possible to reduce complexity of the UE and reduce the waste in power consumption thereof, and reduce the signaling overhead of the network, thereby achieving efficient use of resources.
摘要:
A method and apparatus for establishing an RRC connection are provided, in which a UE compares the strength of a signal received from a serving cell with a threshold, upon receipt of a request for RRC connection establishment, transmits an RRC connection request message to a RAN, measures the strengths of signals from neighbor cells during a first time period and monitors a downlink channel of the serving cell to receive a response message for the RRC connection request message during a second time period, if the signal strength of the serving cell is less than the threshold, and receives the response message from the RAN on the downlink channel.

摘要:
A method and apparatus for transmitting and receiving CQI in a wireless communication system are provided, in which when a UE transitions from a continuous reception state to a DRX state, CQI report resources are reallocated to the UE according to a CQI report resource reallocation rule agreed between the UE and an E-RAN, which obviates the need for signaling information about allocated new CQI report resources.
