Abstract: A method comprises receiving a handover request from a source BS, the handover request comprising a request for a handover of a UE involved in at least two QoS flows using a first MRB with the source BS, wherein the apparatus is using at least a second MRB for other UEs; starting to buffer packets for the UE; receiving a subsequent message comprising, for each of the at least two QoS flows, a CN SN of a first packet not transmitted by the source BS for that QoS flow; identifying a second packet with the highest protocol entity SN according to a protocol entity transmission order of the second MRB among packets which the source BS has delivered to the UE using the first MRB and the apparatus has transmitted to the other UEs using the second MRB; and transmitting a message configuring the UE to use the second MRB.

Abstract: Systems, methods, apparatuses, and computer program products for conditional handover (CHO) execution with network slice service continuity prioritization are provided. A radio resource control (RRC) reconfiguration message sent by a source radio access network (RAN) node to the user equipment (UE) may include, for each CHO configuration, an associated network slice-related priority index. The UE may take this index into account when selecting a suitable cell during CHO recovery. Additionally, or alternatively, the RRC reconfiguration message sent by a source RAN node may include, for each CHO configuration, an associated network slice support information of the candidate target cell. The message may also include network slice remapping information for any network slice associated with one of the candidate target cells. Using the above network slice-related information received from the network, the UE can prioritize the cell to select during CHO recovery in case more than one suitable cell is available.

Abstract: A reconfiguration message is received at user equipment in a communication system from a disaggregated base station with which the user equipment has a current security context established. The reconfiguration message comprises an instruction to compute a new security context based on a security domain counter value, wherein the security domain counter value represents a given security domain from a plurality of security domains supported by the disaggregated base station. The new security context is computed at the user equipment for the given security domain based on the security domain counter value. A set of security keys are derived from the new security context at the user equipment.

Abstract: Systems, methods, apparatuses, and computer program products for determining random access channel (RACH) resources or parameters based on network slice-based resource allocation classes (RACs) may be provided. A mapping between network slices and a set of RACs may be determined by a core network (CN). The CN may send this mapping to the UE. The UE may select RACH resources or parameters for a network slice. The radio access network (RAN) may determine a mapping between the RACs and the RACH resources or parameters. The UE may determine the corresponding RACH resources or parameters to be used for a RAC.
