Abstract: It is provided a method comprising monitoring if a source cell intends performing a radio reconfiguration of a terminal configured with a conditional handover from the source cell to a target cell; determining a determined category among plural predetermined categories; wherein the radio reconfiguration is associated to the determined category; for each category a respective predetermined sequence of one or more operations is defined; the respective predetermined of one of the categories is different from the respective predetermined sequence of another one of the categories; and the method further comprises inhibiting the performing of the radio reconfiguration of the terminal unless the predetermined sequence of one or more operations of the determined category is performed along with the performing of the radio reconfiguration if the source cell intends performing the radio reconfiguration of the terminal.

Abstract: There is provided an apparatus that includes at least one processor and at least one memory storing instructions. The instructions, when executed by the at least one processor, cause the apparatus at least to, receive a list of features of radio resource control (RRC) configuration, where the list is provided by a target secondary node (target SN) of a conditional handover (CHO) procedure, and where the list indicates, for each feature of the list of features of RRC configuration, whether a change in the respective feature requires cancellation or re-initialization of CHO; and, during the CHO procedure, based on information regarding a secondary cell group (SCG) reconfiguration for a source secondary node (source SN), compare the information with the list to determine whether the SCG reconfiguration requires cancellation or re-initialization of the CHO procedure.

Abstract: This specification describes a method comprising responding to a detection of a variation in at least one measured characteristic of a reference signal transmitted from an access point to a portable device by triggering participation by the portable device in vehicle-to-portable device communications. In some examples, the triggering of the participation in the vehicle-to-portable device communications in response to the detection of the variation in the at least one measured characteristic of the reference signal may be performed only if it has been determined that a location of the portable device satisfies a predetermined condition.

Abstract: Methods and apparatus, including computer program products, are provided for conditional handovers. In some example embodiments, there may be provided a method including sending, by a first node serving a user equipment, a message to a second node, the message including an indication of whether a conditional cell change is prohibited at the second node; and receiving, by the first node, an acknowledgment in response to the message.

Abstract: An apparatus includes circuitry configured to: initiate a conditional handover preparation for a conditional handover to change communication access for a user equipment from a source node to a target node; receive a cost from the target node following the conditional handover preparation; receive a cause indicating a trigger for sending the cost, an indication of a type of the cost, and a range for the cost, where the cause characterizes a value of the cost to indicate the type of the cost; the cost being based on resource utilization of the target node, the resource utilization being related to providing communication access for the user equipment following the conditional handover preparation; and adjust a policy related to an initiation of a subsequent conditional handover preparation for the user equipment to the target node, the policy adjusted based on the cost to enhance the resource utilization of the target node.

Abstract: Embodiments of the present disclosure relate to for handover. In response to reception of a request for handover of a second device from a third device to a first device, the first device transmit to the third device an indication that a radio bearer for the second device is to be changed from a split bearer terminated in a fourth device to a Master Cell Group bearer terminated in the first device, the second device being in dual connectivity with the third and fourth devices. The first device receives from the third device a transmission status of data associated with the radio bearer.

Abstract: A method may include receiving, by a secondary node of a third radio access technology (RAT) that is operating as a secondary node for an inter-radio access technology (inter-RAT) dual connectivity connection with a user device from a master node of a first RAT that is operating as a master node for the inter-RAT dual connectivity connection with the user device, a release request including a forward without sequence number indication that instructs the secondary node of the third RAT to forward, without sequence numbers, data for the dual connectivity connection to a target node of a second RAT, wherein the second RAT is different than the first RAT; and forwarding, by the secondary node of the third RAT towards the target node of the second RAT, via a data forwarding path that omits the master node of the first RAT, data without sequence numbers to the target node.
