Abstract: Embodiments of the present disclosure relate to device, method, apparatus and computer readable storage medium of serving cell change procedure utilizing the multiple candidate target cells. The method comprises receiving, from a second device, configuration information associated with a serving cell change procedure of the first device, the configuration information indicating at least a first candidate cell managed by a third device and a second candidate cell managed by a fourth device available for the serving cell change procedure; performing, during the serving cell change procedure, a first random access procedure to access the first candidate cell and a second random access procedure to access the second candidate cell; and accessing to a target cell determined from the first candidate cell and the second candidate cell after the serving cell change procedure is completed. In this way, the interruption time corresponding to CHO or CPC procedure when multiple candidates are available can be reduced.

Abstract: A UE receives configuration from a source cell for conditional handover for target cell(s). At least one of the target cell(s) also supports DAPS handover. The UE determines that either a RLF or HOF has occurred. The UE selects one of the target cell(s) for a handover, and performs a process for handover to the selected target cell. A UE receives individual handover commands and corresponding configuration for conditional handover for target cell(s) and an indication to use DAPS handover if possible in response to a handover. The UE determined condition(s) for handover to one of the target cell(s) have triggered, wherein the one target cell supports DAPS handover. The UE performs, based on the indication to use DAPS handover if possible in response to a handover, handover by the user equipment to the one target cell without releasing the source cell while accessing the one target cell.

Abstract: A method comprising transmitting a configuration of a default time period, wherein the default time period is for allowing a terminal device to consider a request for leaving an active network connection to a first network as accepted by the first network if the first network does not send a response within that the default period, to the terminal device, receiving a first message, from the terminal device, indicating a request to leave the active network connection, determining an overriding condition that overrides the default time period for leaving the active network condition and transmitting, to the terminal device, a second message comprising the overriding condition.

Abstract: Systems, methods, apparatuses, and computer program products for data transmission with stateless routing are provided. Certain embodiments may include a radio resource control (RRC)-less or RRC-based mechanism for short data transmission (SDT) in an RRC inactive state, where the mechanism may be performed without storing or establishing a UE context in a distributed unit (DU), for a UE served by a single CU-user plane (UP). Certain embodiments may include a RRC-less mechanism for SDT in an RRC inactive state, where the authentication of the user equipment (UE) may be performed at the UP using UP integrity protection (IP) in a CU-UP. Certain embodiments may include a RRC-based mechanism for SDT in an RRC inactive state, where the authentication of the UE may be performed at the UP using UP IP in a CU-UP and/or at the CP using CP IP in a CU-CP.

Abstract: Techniques of preserving UE and network resources while performing a paging procedure during cell congestion includes a network node informing a UE if the cell to which the UE is attempting to access is too congested to serve the UE. When a gNB, serving a cell, receives a paging request for the gNB to serve a UE, the gNB first performs a pro-active admission control operation to determine whether there are sufficient resources to serve the UE. When there is too much congestion, the gNB may not admit the UE to the cell and sends RAN raging with a paging flag indicating that the gNB will not serve the UE. The UE in response does not trigger a service request, but rather sends an ACK paging over RRC to the gNB, which in turn notifies the AMF of non-service and that the UE is present.
