    Abstract: The present invention is about conditional handover (CHO) in telecommunications networks, and a main point is to pass the responsibility to a target Master Node for triggering the UE to rapid access to Primary Secondary Cell after applying target Primary Cell configuration during a CHO-NR-DC handover. The target MN decides whether to wait further to execute CPC. If measurements are hopeful, completion of execution of the primary secondary cell for dual connectivity is postponed, and L3 measurement results are inspected from the UE. There are three variants, when the target MN requests the UE to access the target Secondary Node; namely RRC-based access target SN trigger, PDCCH-order-based variant and DL MCE-based variant.

    Abstract: In accordance with an example embodiment of the present disclosure an apparatus that is caused to receive, at a central unit, CU, a first indication of a random access, RA, attempt associated with a first user equipment, the first indication comprising a RA preamble ID, RAPID; a RA radio network temporary identifier, RA-RNTI; and an identifier of a target cell; to start a collision detection timer responsive to receiving the first indication; and to determine a preamble collision related to timing advance, TA, acquisition in a Layer1/Layer2 triggered mobility procedure, responsive to receiving, at the CU, during the collision detection timer is running, a second indication of an RA attempt associated with a second user equipment, the second indication comprising the same RAPID, RA-RNTI and identifier of the target cell as the first indication.

    CPC classification number: H04W36/0058 ,  H04W36/0061

    Abstract: A method includes receiving via a serving cell that is associated with a first distributed unit of the network node, a list of conflicting physical cell identities and a request to provide an indication of whether a measured cell is intra-distributed unit or inter-distributed unit with respect to the serving cell; determining a physical cell group identifier of the serving cell; determining, by the user equipment, a physical cell group identifier of the measured cell; comparing the physical cell group identifier of the measured cell to the physical cell group identifier of the serving cell, to determine whether: the measured cell is intra-distributed unit with respect to the serving cell, or the measured cell is inter-distributed unit with respect to the serving cell; and sending a layer 1 measurement report including information indicating whether the measured cell is intra-distributed unit or inter-distributed unit with respect to the serving cell.

    Abstract: An apparatus comprising means for sending a response to the first target master node based on the received first request in response to receiving a first secondary node addition request for the user equipment from a first target master node, means for sending a response to the second target master node based on the received second request in response to receiving a second secondary node addition request from a second target master node for the same user equipment; and means for enabling, in response to receiving a physical uplink shared channel message from the user equipment, decoding of the physical uplink shared channel message received from the user equipment based on a first target master node key associated with the first target master node in case no information is available whether user equipment accessed first or second target master node, and, if decoding with the first key not successful, decoding based on a second target master node key associated with the second target master node.

    Abstract: Systems, methods, apparatuses, and computer program products for uplink switch to source cell in dual active protocol stack handover. A method may include receiving a handover command. The method may also include identifying a maximum permissible exposure event at a user equipment before or after reception of the handover command. The method may further include delaying an uplink switch to a target network element from a source network element due to the maximum permissible exposure event, or switching back to the source network element. According to certain example embodiments, delaying the uplink switch may include setting an event trigger to switch to the target network element. In addition, the method may include informing the target network element about the maximum permissible exposure event, and about the delay in the uplink switch.
