A method of UE includes receiving a radio resource control (RRC) message for configuring bandwidth parts (BWPs) of a serving cell, receiving a physical downlink control channel (PDCCH) indicating activation of a first BWP, performing a BWP switching to the first BWP indicated by the PDCCH, and starting a first downlink BWP timer associated with the first BWP. A UE includes a transceiver, and at least one controller coupled with the transceiver, the at least one controller configured to receive an RRC message for configuring BWPs of a serving cell, receive a PDCCH indicating activation of a first BWP, perform a BWP switching to the first BWP indicated by the PDCCH, and start a first downlink BWP timer associated with the first BWP.

This disclosure provides systems, methods, apparatuses and computer-readable medium for wireless communication. In some aspects, a user equipment (UE) may receive, from a first base station (BS) associated with a fifth generation New Radio (5G NR) radio access technology (RAT), a command of mobility from the 5G NR RAT to a second RAT. The UE may determine that the command of mobility is for voice fallback. The UE may transmit, to a second BS associated with the second RAT and based at least in part on determining that the command of mobility is for voice fallback, a radio resource control (RRC) connection request communication for attempting to communicatively connect with the second BS for voice fallback.

Systems, methods, and instrumentalities are disclosed for network slice selection and/or reselection. A WTRU may receive updated assistance information for network slice selection and/or reselection. The WTRU may apply local policies to determine when to use the updated assistance information to access a network slice. The WTRU may determine whether to contact an existing network slice function or a new network slice function to establish a connection to a network slice. Based on the determination, the WTRU may transmit different information to the network. The network slice selection and/or reselection may be initiated by a WTRU or by a network.

Provided are an address coordination method and device, a base station, a session management function (SMF) network element and a storage medium. In a handover process of a terminal from a source base station side to a target base station side, a UPF split state of a PDU session of the terminal may be determined and data transmission tunnel address coordination may be implemented, thereby enhancing flexibility of split control of the PDU session in the handover process of the terminal, preventing the target base station side from executing PDU session resource modify/modification indication and other processes again to perform the data transmission tunnel address coordination after the terminal completes the handover. Resource admission control efficiency of the target base station side can be improved, so that the PDU session enters a reasonable state of UPF split or UPF non-split, and signaling resources can be saved.

A first network device may receive a notification over a network; in response to the notification, cause a virtualized operating system (OS) and a hypervisor of the first network device to obtain state units from one or more of first hardware components and virtual components; create a context state transfer package (CSTP) based on the state units; and forward the CSTP from the first network device to a second network device over the network. The second network device may receive the CSTP from the first network device; unpack the CSTP to obtain the state units; and put, at the second network device, second hardware components and virtual components of the second network device in a same state as the first hardware components and virtual components when the state units were obtained at the first network device.

The present disclosure relates to a communication technique for fusing a 5G communication system with IoT technology to support a higher data rate than a 4G system, and a system thereof. The present disclosure can be applied to intelligent services (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, healthcare, digital education, retail, security and safety related services, etc.) on the basis of 5G communication technology and IoT-related technology. According to one embodiment of the present disclosure, provided is a method of a first server in a wireless communication system. The method of the first server is characterized by comprising the steps of: receiving first information on whether a relocation procedure of an application context can be started from at least one of a terminal and an application server; confirming second information related to the relocation procedure of the application context on the basis of the first information; transmitting the second information to the terminal and the application server; and when it is confirmed that the relocation procedure of the application context is being performed, transmitting an indicator indicating that the relocation procedure of the application context is in progress to the terminal and the application server.

Disclosed are a slice processing method and apparatus, a storage medium, and a processor. The method includes: obtaining, by a first network side device, a first handover request sent from a source base station, and determining a handover behavior based on slice information.

Methods, systems, and devices for inter-donor topology adaptation in integrated access and backhaul (IAB) networks are described. An example method for wireless communication includes transmitting, by a source donor, a first message comprising an indication that a migrating IAB node is configured to perform an inter-donor switching operation, and receiving a second message comprising feedback information, wherein the source donor is communicatively coupled to the migrating IAB node and a plurality of nodes that are downstream from the migrating IAB node.
