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.

Abstract: Systems, methods, apparatuses, and computer program products for survival time dependent flexible handover execution are provided. One method may include providing, by a network node, at least one handover execution condition to at least one user equipment. The at least one handover execution condition may include one or more delta values with respect to one or more actual handover execution conditions to allow for early and/or late execution of a handover by the at least one user equipment. The method may also include indicating, to the at least one user equipment, a transfer interval and/or a survival time information for which the at least one handover execution condition is taken into account.

Abstract: Method, apparatuses, and computer program products provide means for monitoring time sources for nodes of a network and providing timing resiliency solutions. An example method includes: establishing time synchronization within a network comprising a plurality of nodes using a time source; receiving an indication regarding at least one of degradation or failure of the time source for at least one node; receiving an indication regarding at least recovery of the time source for the at least one node; and determining, within the network, an action to be taken to upon failure at the at least one node in response to the at least one of the degradation or the failure of the time source for the at least one node, where the action to be taken comprises instructing the at least one node to leverage either hold over functionality or a backup time source.

Abstract: Systems, methods, apparatuses, and computer program products for supporting precision timing protocol (PTP) based time sensitive network (TSN) applications are provided. One method includes configuring, by a network node, a user equipment connection and user contexts for an industrial automation and control (IAC) system or configuring at least one time synchronized radio bearer for a user equipment. The method may also include determining synchronization configuration on the at least one time synchronized radio bearer for the industrial automation and control (IAC) system, and distributing the synchronization configuration periodically or on a need basis to one or more serving network nodes for the industrial automation and control (IAC) system.

Abstract: A network node may determine a congestion level of a random access channel; and may transmit, to one or more energy constrained user equipments, at least one barring parameter, wherein the at least one barring parameter may be based, at least partially, on the determined congestion level and an energy constraint of the one or more user equipments. An energy constrained user equipment may receive a system information block comprising a barring factor and a back-off time; may determine whether to transmit a preamble for a random access procedure based, at least partially, on the barring factor and a maximum number of preamble transmission attempts; may transmit the preamble based on a determination to do so, or may wait for the back-off time based on a determination to not do so.

Abstract: Various techniques are provided for a method including broadcasting, by a network node, a discontinuous reception (DRX) switch message indicating a user equipment (UE) is to switch from a first DRX cycle to a second DRX cycle and determining, by the network node, whether to send a paging message to the UE using one of the first DRX cycle or the second DRX cycle. The method can further include determining, by the network node, that the network node is in a reduced resource state.
