Cross Link Interference (CLI) within a wireless network is mitigated by characterizing a communication path that introduces the CLI on an uplink resource. Mitigation is achieved by receiving, from a neighboring device, information related to a downlink resource scheduling decision. The neighboring device then delays its downlink resource transmission. Transmissions received on an uplink resource may then be corrected.

Cross link interference mitigation for full duplex wireless systems

Embodiments provide novel approaches to handling network slice groups in access stratum and non-access stratum communications in a cellular communication network. Novel slice identification schema can support group-level identification of groups of network slices without individually listing the network slices. Some embodiments implement a slice identifier that supports wildcard slice/service type (SST) options and/or wildcard slice differentiator (SD) options to support wildcard-enabled slice groups. Some embodiments enable use of such wildcard-enabled slice groups in context of unified access control. Some embodiments introduce a novel criteria type to unified access control to expressly support flexible slice grouping.

An apparatus comprises a memory and a processor communicatively coupled to one another. The memory may be configured to store one or more directories comprising access to multiple tenant profiles and one or more network access commands configured to provide access to one or more entitlements. Each tenant profile of the tenant profiles are associated with one or more services. The processor may be configured to receive a request to access at least one service. The request comprises an application function identifier (AFID) comprising a tenant ID that references a tenant profile of the tenant profiles, a department ID that references multiple entitlements associated with the tenant profile, and an API ID that references a service associated with the entitlements. Further, the processor may be configured to generate a report comprising multiple network access commands configured to enable access to the service in accordance with the entitlements.

System and method to map hierarchical multi-tenant access to services

Technologies for efficient handover in 5G networks are disclosed. An example method includes responsive to detecting that a user device is located in a geographic area with overlapping 5G coverage from a first gNB and a second gNB and that the user device is moving away from the first gNB's coverage toward the second gNB's coverage, determining to perform a light inter-gNB handover of the user device, and causing execution of the light inter-gNB handover by at least causing a physical switch from a physical CU-CP of the first gNB to a physical CU-CP of the second gNB, a logical switch from a logical CU-UP of the first gNB to a logical CU-UP of the second gNB, a logical switch from a logical DU of the first gNB to a logical DU of the second gBN, and a logical switch from a logical RU of the first gNB to a logical RU of the second gBN, wherein the logical switches are performed without transfer of context data associated with the user device.

Efficient handover in 5G networks

Data center architectures for providing Network Functions (NFs) in telecommunications networks are disclosed. A 5G or 6G wireless service provider with an existing 5G or 6G core network in one or more clouds can add several NFs in another cloud to optimize certain service(s). These NFs may already exist in the core, but for different services. A 4G Long Term Evolution (LTE) customer could also incrementally migrate to a public cloud rather than migrating all NFs at once.

Disclosed is a method performed by a UE device that routes traffic to a 5G Core Network. The method includes receiving a first ATSSS rule including first traffic descriptor information and first steering mode information that identifies a first 3GPP access network operated by a first MNO, and a second ATSSS rule including second traffic descriptor information and second steering mode information that identifies a second 3GPP access network operated by the first MNO or a second MNO; transmitting a first type of traffic corresponding to the first traffic descriptor information included in the first ATSSS rule to the first 3GPP access network operated by the first MNO; and transmitting the first type of traffic or a second type of traffic corresponding to the second traffic descriptor information included in the second ATSSS rule to the second 3GPP access network operated by the first MNO or the second MNO.

The UE may schedule and transmit the same data using at least two separate grant-free transmission configurations.

Embodiments are directed towards systems and methods for user plane function (UPF) and network slice load balancing within a 5G network. Example embodiments include systems and methods for load balancing based on current UPF load and thresholds that depend on UPF capacity; UPF load balancing using predicted throughput of new UE on the network based on network data analytics; UPF load balancing based on special considerations for low latency traffic; UPF load balancing supporting multiple slices, maintaining several load-thresholds for each UPF and each slice depending on the UPF and network slice capacity; and UPF load balancing using predicted central processing unit (CPU) utilization and/or predicted memory utilization of new UE on the network based on network data analytics.

A first cellular network may connect user equipment (UE) with a data network using a first anchor point. The first cellular network may transition the UE from the first anchor point to a second anchor point. Following the transitioning, the first cellular network may connect the UE with the data network using the second anchor point. The UE may then be transitioned from the second anchor point to a converged anchor point of the first cellular network. The UE may be locked to the converged anchor point while the UE is communicating with a second cellular network.

Various systems and methods for scheduling data transmissions from a base station to user equipment (UE) are presented. Channel quality indicator values that correspond to multiple UE may be determined for multiple carrier components of a cellular network's carrier aggregation. A scheduling matrix may be created that includes instantaneous data transfer rates for the UE. Elements within the scheduling matrix may be normalized by modifying instantaneous data transmission rates using average data transmission rates. Scheduling decisions for data transfers may be made for the UE based on the normalized scheduling matrix.

Various arrangements are presented for managing anchor point movement on a cellular network. A user equipment (UE) can be connected with the Internet via a first anchor point (e.g., user plane function) of the cellular network. A network data analytics function (NWDAF) within a core of the cellular network can analyze one or more characteristics of the piece of UE. Based on the analysis, a second anchor point is selected and the piece of UE is connected with the selected second anchor point such that the piece of UE accesses the Internet via the second anchor point.
