Abstract: Embodiments of the present disclosure relate to methods, devices, and medium for communication. A method of communication comprises in accordance with a determination that a condition for performing a configuration for a primary secondary cell (PScell) of a secondary cell group (SCG) of a second network device is met, determining, at a terminal device served by a first network device, whether the SCG of the second network device is deactivated. The method further comprises in accordance with a determination that the SCG is deactivated, transmitting a third message to the second network device of the SCG, the third message indicating that the configuration for the PScell has been completed by the terminal device.

Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable media for communication. A first network device receives a first paging message from a second network device in a RAN, the first paging message comprising information on a MT-SDT for a terminal device, and determines, based on the information, whether the MT-SDT is performed for the terminal device. If the MT-SDT is performed for the terminal device, the first network device transmits, to the terminal device, a second paging message comprising an indication indicating that the MT-SDT is performed for the terminal device. In this way, the MT-SDT procedure can be triggered.

Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable media for communication. A terminal device receives a set of configurations for a set of candidate cells. The terminal device determines a reference configuration, and applies, based on the reference configuration, a configuration for a candidate cell in the set of configurations. In this way, a delta configuration may be supported for subsequent conditional cell change or L1/L2 based mobility.

Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable media for communication. The method comprises if first uplink data from at least one radio bearer not supporting a transmission in an inactive state arrives during a transmission of second uplink data in the inactive state, a terminal device generates an indication indicating the arriving of the first uplink data and transmits the indication to a network device. In this way, the transmission in the inactive state can be ensured to be finished in an efficiency way.

Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable media for communication. A network device transmits, to a terminal device, a configuration regarding a storing of information concerning a change of a primary cell of a secondary node, the network device being the secondary node or a master node. Based on the configuration, the terminal device stores the information concerning the change of the primary cell of the secondary node. In this way, a very flexible reporting of the change of the primary cell of the secondary node can be achieved.

Abstract: Example embodiments of the present disclosure relate to UP transmission for a device in an inactive mode. A first network device transmits data received from a terminal device in an inactive mode via a connection established for the terminal device between the first network device and the second network device to a second network device, and transmits, to the second network device, a first indication indicating a termination of a data transmission related with the terminal device if a first condition is met. Through this solution, the connection established for the terminal device in the inactive mode between the first network device and the second network device to a second network device may be terminated suitable.

Abstract: Embodiments of the present disclosure relate to methods, devices, and medium for communication. A method of communication comprises determining, at a terminal device served by a first network device, that uplink transmission is to be performed with a second network device serving the terminal device. The method further comprises transmitting, to the first network device, a request to activate a cell group of the second network device, the request comprising characteristic information concerning the uplink transmission.
