A method performed by user equipment is a method of an RRC connection re-establishment procedure performed by user equipment (UE), and includes the following steps: triggering or initiating, by the UE, an RRC connection re-establishment procedure; during initiation of the RRC connection re-establishment procedure, starting, by the UE, a timer T, and performing cell selection or relay selection; and in the case that the UE has selected a suitable cell or the UE has selected a suitable relay, stopping, by the UE, T, wherein the suitable cell is a cell of which a measured value or a level value meets a cell selection rule, and the suitable relay is a relay of which a measured value or a level value meets a relay selection rule.

Method performed by user equipment, and user equipment

A method performed by a user equipment (UE) is provided. The method detects a failure in a master cell group (MCG) transmission. The method, after determining that the UE is configured with a resume timer, transmits a message to a base station (BS). The message includes information related to the failure. The method also starts the resume timer upon sending the message to the BS, and triggers a radio resource control (RRC) connection re-establishment procedure when the resume timer expires.

Control method of user equipment and user equipment

A method performed by a base station (BS) is provided. The method receives, from a user equipment (UE), a message indicating that the UE is capable of performing a conditional handover. The method then transmits, to the UE, a set of one or more conditional handover configurations. Each conditional handover configuration in the set of conditional handover configurations includes information associated with a corresponding candidate cell, and a handover condition comprising a measurement event based on a signal quality of at least one of a serving cell and the corresponding candidate cell.

Method and device for conditional handover

The radio link failure reporting method comprises: user equipment (UE) detecting a radio link failure (RLF) of a master cell group (MCG); the UE initiating a fast MCG link recovery procedure to recover a connection to a network side; the UE transmitting a radio link failure report to the network side, wherein the radio link failure report comprises first fast MCG link recovery information, and the first fast MCG link recovery information is used to indicate that the UE has attempted a fast MCG link recovery function based on the fast MCG link recovery procedure after a radio link corresponding to the radio link failure report fails.

Radio link failure reporting method and user equipment

The present application provides a method executed by a user equipment, comprising: receiving a first system information (SI) message, wherein the first system information (SI) message comprises type information related to a system information block (SIB) and scheduling information of a second system information (SI) message to which the type of the SIB belongs, and the scheduling information comprises a time when the second SI message appears and indication information indicating whether the second SI message is broadcast; and if the indication information indicates that the second SI message is not broadcast, sending an SI request message, and receiving a needed system information block (SIB) according to the scheduling information in the received first SI message. The present application further provides a corresponding user equipment and base station. By means of the present invention, unnecessary overheads are avoided and system resources are saved while meeting the demand of a UE acquiring information.
