A first base station receives, from a second base station, a message comprising at least one parameter of a first cell of the second base station. The at least one parameter indicates that the first cell supports at least one vehicle-to-everything (V2X) service. A handover decision for a wireless device is made. The first base station sends, to the second base station, a handover request for the wireless device based on the handover decision and the message.

A gateway station switching method and apparatus. When quality of a link from a terminal device to a source gateway station through a satellite is poor, the source gateway station sends third indication information to a target gateway station, so that the target gateway station feeds back second channel quality to the source gateway station, that is, quality of a link from the terminal device to the target gateway station through the satellite. The source gateway station determines, based on the second channel quality and first channel quality that represents the quality of the link from the terminal device to the source gateway station through the satellite, whether to switch the terminal device to the target gateway station.

This disclosure relates to techniques for performing consecutive conditional handovers. A cellular base station may provide conditional handover information for multiple conditional handovers to a wireless device. The conditional handover information may include information for performing a conditional handover from a cell provided by the cellular base station to at least one cell, and information for performing a conditional handover from one or more of those cells to at least one cell. The wireless device may perform multiple consecutive conditional handovers using the conditional handover information.

A method performed by a wireless device (18) comprises receiving (250), from a master node (12A) for multi-connectivity operation, a configuration message (20) which includes a master configuration (28) and one or more conditional PSCell configurations (22). The method also comprises transmitting (260) a first message (26) in response to the configuration message (20). The first message (26) indicates acknowledgement of receipt, applying of, and/or understanding of the master configuration (28). The method also comprises, after transmitting (260) the first message (26), when the condition for applying the PSCell configuration (22) of at least one of the one or more conditional PSCell configurations (22) is fulfilled, transmitting (270), to the master node (12A), a second message (30) that includes an indication (24) indicating application by the wireless device (18) of the PSCell configuration (22) of at least one of the one or more PSCell configurations (22).

An SN (100C) includes a transmitting unit (110b) that transmits, to an MN (100A) to which a terminal (200) is connected, a first message including configuration information of a cell formed by the SN (100C), and a control unit (140b) that determines to delete the configuration information of the cell according to a state of the cell. The transmitting unit (110b) transmits, to the MN (100A), a second message instructing deletion of the configuration information of the cell.

A wireless terminal comprises receiver circuitry and processor circuitry. The receiver circuitry is configured to receive a message. The message comprises one or more conditional handover configurations; at least one indication; and, at least one triggering condition; each of the one or more conditional handover configurations comprising at least one identity of a candidate target cell, the at least one indication indicating whether or not the message is provided as full configuration. The processor circuitry is configured to: store the one or more conditional handover configurations and the at least one indication; perform a handover to a target cell; and determine validity of the one or more conditional handover configurations based on the indication upon or after performing the handover.

Example aspects include a method, apparatus, and computer-readable medium for network-triggered reestablishment by a network node of a wireless communication network, comprising transmitting, to a user equipment (UE) in a connected state with a first central unit (CU), an indication to perform a radio resource control (RRC) reestablishment procedure with a second CU. The indication comprises a reestablishment cell identifier. The aspects further include performing the RRC reestablishment procedure with the UE to transfer the UE from the first CU to the second CU using the reestablishment cell identifier.

Provided are a method of performing cell reselection and a device supporting the method. According to one embodiment of the present disclosure, the method includes: starting data transmission or data reception while the UE is in radio resource control (RRC) idle state or RRC inactive state; applying an offset value to a serving cell for cell reselection; performing cell reselection based on the applied offset value, during the data transmission or data reception; and stopping applying the offset value to the serving cell, when the data transmission or data reception is succeeded.

A wireless transmit/receive unit (WTRU) is configured to determine a frequency location of a reduced frequency bandwidth within a full system frequency bandwidth for an uplink transmission. The reduced frequency bandwidth is based on a received MTC physical downlink control channel. The WTRU is configured to determine a frequency location of an uplink resource in a first subframe based on at least one of a subframe number of the first subframe, a transmission repetition number associated with the first subframe, or a coverage enhancement level of the WTRU. The WTRU is configured to send a physical uplink control channel (PUCCH) transmission in the uplink resource in the first subframe in a same frequency location in both slots of the first subframe. A format of the PUCCH transmission is limited to a subset of PUCCH formats available for a WTRU operating in the full system frequency bandwidth.

Provided is a method performed by a user equipment (UE) in a wireless communication system. The method includes: receiving, from a source base station, a first radio resource control (RRC) reconfiguration message including configuration information indicating reconfiguration with sync, identification information of a bearer, and dual active protocol stack (DAPS) configuration information indicating that the bearer is configured as a DAPS bearer; reconfiguring a packet data convergence protocol (PDCP) entity of the UE with respect to the bearer; switching uplink data transmission from the source base station to a target base station; and releasing the source base station.
