The method includes: sending, by a network device, at least one handover command corresponding to a plurality of target network devices to a terminal device. The at least one handover command corresponding to the plurality of target network devices includes a first handover command, and the first handover command includes configuration information of a first target network device among the plurality of target network devices, so that the terminal device starts a first access timer corresponding to the first target network device in response to that the terminal device determines to establish a connection with the first target network device. The terminal device establishes a connection with the first target network device according to the first access timer.

One method may include transmitting a first signal instructing a user equipment (UE) to transition a state of a secondary cell associated with the UE; determining an allocation of resources for the UE to communicate with the secondary cell; and transmitting a second signal including an indication of an active bandwidth part (BWP) used for the allocation of resources based on the determining. The active BWP and the first signal may indicate the transition of the state of the secondary cell.

A method performed by a master node (MN) serving a wireless device with a secondary node (SN) in dual connectivity (DC) in a wireless communication system, the method including: transmitting, to the wireless device, a conditional primary serving cell (PSCell) mobility command for a first cell in the SN; transmitting, to the SN, a message requesting a modification of the conditional PSCell mobility command for the first cell, the message including an identity (ID) of the wireless device, a target cell ID of the first cell for which the conditional PSCell mobility is to be modified, and an indication to modify the conditional PSCell mobility command for the first cell; receiving, from the SN, an acknowledgement (ACK) message for modification of the conditional PSCell mobility command for the first cell; and transmitting, to the wireless device, information related to modification of the conditional PSCell mobility command for the first cell.
