The present disclosure may provide a method of operating a terminal operating based on a plurality of networks in a wireless communication system. Herein, the method of operating the terminal may include: establishing a connection to a first network; receiving a paging message from a second network; transmitting, to the first network, a message for indicating temporary suspension of data communication with the first network; and transitioning to the second network. Herein, the message for indicating the temporary suspension of data communication with the first network may include paging-related information of the first network, and when the terminal receives a paging message from the first network after transitioning to the second network, the terminal may determine whether or not to transition to the first network.

Method and apparatus for transitioning between networks in a wireless communication system

The present disclosure relates to a method for operating a terminal and a base station in a wireless communication system and an apparatus for supporting the same. In an embodiment of the present disclosure, a method for operating a user equipment (UE) in a wireless communication system may include, performing communication through a link established between the UE and another UE; transmitting a first message for requesting an update of an identifier of the link; receiving a second message for responding to the first message; and reestablishing a packet data convergence protocol (PDCP) entity of the UE based on the update of the identifier.

Method and device for controlling configuration related to sidelink communication in wireless communication system

A user equipment (UE) receives a timing advance medium access control (MAC) control element. The UE applies a timing advance command of the timing advance MAC control element and to start or restart a time alignment timer. The UE releases physical uplink control channel (PUCCH) resources and releases any assignment sounding reference signal (SRS) resources, when the time alignment timer expires. The UE flushes hybrid automatic request (HARQ) buffers, when the time alignment timer expires or is stopped.

A method for performing random access in a wireless communication system is provided. The method includes transmitting a preamble for random access in uplink, receiving a random access response message including back-off information as a response to the preamble, and performing back-off using the back-off information when the random access has failed.

Method for signaling back-off information in random access

A mobile communication technology, and, more particularly, a method for efficiently transmitting data stored in a message 3 (Msg3) buffer and a user equipment for the same is disclosed. The method of transmitting data by a user equipment in uplink includes receiving an uplink (UP) Grant signal from a base station on a specific message, determining whether there is data stored in a message 3 (Msg3) buffer when receiving the UL Grant signal on the specific message, determining whether the specific message is a random access response message, and transmitting the data stored in the Msg3 buffer to the base station using the UL Grant signal received on the specific message, if there is data stored in the Msg3 buffer when receiving the UL Grant signal on the specific message and the specific message is the random access response message.

Data transmission method and user equipment for the same

A PDCP status report can be transmitted with reduced 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. A PDCP control packet data unit (PDU) is generated to communicate a status report to a transmitting node for one or more PDCP SDUs transmitted from the 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 bit in the variable length bitmap indicates whether a corresponding one of the one or more PDCP SDUs has been successfully been received.

Transmitting and receiving a PDCP layer status report in a mobile telecommunications system

A method for a user equipment (UE) to generate a transmission is provided. In this method, a UE starts a time alignment timer when a time alignment command is received. The UE receives an uplink grant; and generates an initial transmission or a retransmission according to the uplink grant only when the time alignment timer is running upon receiving the uplink grant. In addition, the uplink grant is received through a Physical Downlink Control Channel (PDCCH) indicated by a Cell Radio Network Temporary Identifier (C-RNTI) of the UE.

Method for transmitting and receiving signals in consideration of time alignment timer and user equipment for the same

In a wireless mobile communications system, a method of transmitting and receiving radio access information that allows a faster and an efficient way of establishing a radio connection between a terminal and a target base station while performing a handover for the terminal to a cell of the target base station. The network transmits in advance, the radio access information and the like, to the terminal so that the terminal can be connected with the target cell in a faster manner which minimizes the total time for the handover process.

Method of transmitting and receiving radio access information in a wireless mobile communications system

The present invention provides a method of receiving a timing advance command by a user equipment in a wireless communication system. A terminal receives information on a time advance group from a base station, and also receives the tuning advance command corresponding to the time advance group from the base station.
