    Abstract: A method includes transmitting packets of first and second traffic subflows via a first radio bearer to a second device; detecting that further packets of the second traffic subflow are to be transmitted via a second radio bearer to the second device; and transmitting a packet data unit via the first radio bearer to the second device, wherein the packet data unit includes an indication of a switch of the second traffic flow. Another method includes receiving from a first device packets of first and second traffic subflows via a first radio bearer; receiving from the first device a packet data unit including an indication that further packets of the second traffic subflow are to be received via a second radio bearer; establishing the second radio bearer between a second device and the first device; and receiving the further packets of the second traffic flow via the second radio bearer.

    Abstract: In accordance with the example embodiments of the invention there is at least a method and apparatus to perform determining, by a device of a communication network, that at least one PDCP PDU of a PDCP sublayer is duplicated for transmission over at least one logical channel; signaling to an RLC sublayer an indication of the at least one PDCP PDU that is duplicated; and based on the signaling, controlling duplication of the at least one PDCP PDU for transmission over the at least one logical channel. Further, there is at least a method and apparatus to perform receiving, at a device of a communication network, an indication through a received signaling indicating that at least one PDCP PDU of a PDCP sublayer is to be duplicated; determining to duplicate the at least one PDCP PDU; duplicating the at least one PDCP PDU based on the determination; and transmitting the duplicated PDCP PDU over at least one logical channel.

    Abstract: Methods and apparatus, including computer program products, are provided for mobility between networks. In some example embodiments, there may be provided a method. The method may include receiving, at a source base station, a single end marker indication for a flow associated with a user equipment being handed over to a target base station; determining, by the source base station and in response to the received single end marker indication, at least one bearer mapped to the flow; generating for each determined bearer, at least one end of marker indication; and sending, over a forwarding path from the source base station to the target base station, the generated at least one end of marker indication. Related systems, methods, and articles of manufacture are also described.

    Abstract: It is provided a method comprising: checking if an indication indicates that a target cell is configured to store concurrently first and second configurations of a terminal, wherein the first configuration is based on a first conditional handover request, and the second configuration data set is based on a second conditional handover request; monitoring if the source cell intends performing a radio reconfiguration of the terminal after the source cell configured the terminal for the first conditional handover; canceling the first conditional handover if the source cell intends performing the radio reconfiguration and the indication does not indicate the concurrently storing; instructing the source cell to request the second conditional handover from the target cell if the source cell intends performing the radio reconfiguration and the indication indicates the concurrently storing.

    Abstract: An apparatus is configured to transmit at least one first random access request by using a first preamble to a first handover target cell or to a first beam provided by a serving cell. If the first random access request is responded, the apparatus carries out a synchronization to the first handover target cell or to the first beam provided by the serving cell. If the first random access request is not responded, the apparatus transmits at least one second random access request by using at least one second preamble to at least one second handover target cell or to at least one second beam provided by the serving cell. The apparatus stores information on not-responded first or second random access requests or resources not used for random access requests, wherein the information comprises preambles used. The apparatus transmits, after being synchronized, the stored information to either the first handover target cell, the at least one second handover target cell or the serving cell for being used in random access resource allocation.
