Dynamic network resource slice partition size adjustment is provided herein. A method can include partitioning resources enabled via a communication network among network slices of the communication network, the network slices comprising an expandable network slice and a contractable network slice, obtaining a resource usage value for the expandable network slice, the resource usage value indicating a first proportion of the resources enabled via the communication network being used by the expandable network slice, and in response to the resource usage value being greater than a threshold, reallocating a portion of the resources enabled via the communication network from the contractable network slice to the expandable network slice, the portion of the resources being defined based on a function of a ratio of the first proportion to a second proportion of the resources enabled via the communication network being used by the contractable network slice.

Embodiments herein provide a wireless communication system for managing a network slice congestion. The wireless communication system includes a User Equipment (UE), operably coupled to a core network. The UE is configured to transmit a first NAS signaling message to the core network, wherein the first NAS signaling message comprises a specific network slide identity. The core network i configured to detect the network slice congestion in the wireless communication system. Further, the core network is configured to indicate the network slice congestion using a second NAS signaling message to the User Equipment (UE), wherein the second NAS signaling message comprising a reject cause value and a back off timer for the requested network slice identity.

Methods, systems, and computer readable media for network slice selection function (NSSF) recovery. A method includes creating, at an NSSF, subscriptions for a number of access and mobility management functions (AMFs) and storing availability information for each AMF. The method includes determining, at the NSSF, that the NSSF failed to process at least one service update message from at least one of the AMFs, and in response, sending a notification request message to each of the AMFs, the notification request message requesting each AMF to update availability information for the AMF. The method includes receiving, at the NSSF, updated availability information from each of the AMFs. The method includes distributing, at the NSSF, the updated availability information to each of the AMFs.

A user equipment (UE) may transmit, using a first radio access technology (RAT), a service request message including information associated with at least one UE service. Based on the transmitted service request message, a message with information to setup a bearer for a second RAT, wherein the second RAT is a different RAT than the first RAT. The UE may receive multimedia data using the second RAT and simultaneously receive data using the first RAT.

Technologies for systems, methods and computer-readable storage media for solving complex distributed congestion in a 5G network by using traffic engineering data to redirect sessions. Specifically, involving anchoring a network node to a User Plane (UP) entity based on traffic engineering data and subscribing to traffic engineering data associated with requested parameters to push particular policies and/or select alternate application functions to correct congestion.

Technologies for providing out-of-order network packet management and selective data flow splitting include a computing device. The computing device includes circuitry to identify a service data flow associated with a set of packets to be sent to a recipient computing device. The circuitry is also to determine a target quality of service for the service data flow, determine, as a function of the target quality of service, one or more radio links on which to send the packets, including determining whether to split the service data flow over multiple radio links, and send the packets through the determined one or more radio links.

A method for congestion mitigation via admission control in a shared-backhaul telecommunications network is disclosed, comprising: assessing a congestion state in a multi-node radio access network having a shared backhaul connection, the congestion state based on congestion of the shared backhaul connection; retrieving an admission control policy based on the congestion state of the shared backhaul connection; performing a policy action of the admission control policy at a first base station acting as a gateway for the multi-node radio access network with respect to the shared backhaul connection; and sending the admission control policy to other nodes in the multi-node radio access network, thereby causing the other nodes to perform the policy action, wherein the policy action is denying a request from a user equipment to attach to the radio access network.

Embodiments of this application provide a contention window management method applied to an unlicensed band. The method includes sending, by a sending device, one or more data packets to one or more receiving devices in one reference time unit or a plurality of reference time units, where the one or more data packets occupy a first bandwidth. The method further includes receiving, by the sending device from the one or more receiving devices, a hybrid automatic repeat request HARQ or HARQs for the one or more data packets. The sending device determines a contention window (CW) size of a second bandwidth with reference to the HARQ or HARQs. The CW update based on HARQ feedback improves communication efficiency.

Various solutions for single network slice selection assistance information (S-NSSAI) based congestion control with respect to user equipment and network apparatus in mobile communications are described. An apparatus may receive a message with a back-off timer from the network node. The apparatus may determine whether an S-NSSAI of a protocol data unit (PDU) session is provided by the network node. The apparatus may start the back-off timer and associate the back-off timer with the S-NSSAI of the PDU session in an event that the S-NSSAI is provided by the network node.

An access point (AP) may be configured by processing circuitry to operate as a coordinator AP for performing BSS channel level coordination. The coordinator AP is configured to assign non-overlapping channels to one or more coordinated APs of overlapping BSSs to schedule time-sensitive traffic to help ensure bounded latency, jitter and reliability per BSS. In some embodiments, the AP may be configured for performing transmission level coordination and may initiate a coordinated transmission opportunity (TXOP) for resource assignment to control contention access among managed BSSs. To perform the BSS channel level coordination, the coordinator AP is configured to encode a multi-AP trigger frame (M-TF) to initiate the coordinated TXOP. The M-TF may be encoded to include a time-sensitive operation IE indicating how each STA is to access the channel within the coordinated TXOP.
