Abstract: A system for scheduling wireless data transmissions divides a band allocated to the mobile service carrier into two overlapping bands. Then each user equipment (UE) of a plurality of UEs that connects to the ground-based network of the mobile service carrier is assigned to one of the two overlapping bands. The system allocates at a given scheduling time, physical resource blocks (PRBs) to UEs up to a maximum number of PRBs available for the particular overlapping frequency band to which the UE is assigned based on a metric for the UE that is a ratio of a downlink channel quality indicator for the UE to the average data rate of the UE at the given time, giving higher priority for PRB allocation to UEs that have a larger metric than other UEs of the plurality of UEs.

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.

Abstract: Methods and systems for scaling energy consumption in wireless network infrastructure, while retaining the ability to quickly scale when load changes. This end is accomplished by using containerized (or virtualized) applications to implement 5G core Network Functions, and utilizing network redundancy/geo-redundancy or a multihoming transport protocol for communication between these containerized (or virtualized) applications and other 5G system elements such as the network functions of the Radio Access Nodes (RANs) or the network functions of 5G Core. In particular, one or more core Network Functions (NFs) are instantiated as containerized applications executing on one or more virtualized hosts in a cloud-native orchestration environment. The containers are selectively activated or deactivated based on a demand for utilization of the associated NF. Because elements of the 5G RAN, 5G Core and one or more NFs are connected to one another via a protocol that supports network redundancy and/or geo-redundancy and/or multihoming, endpoint addressing need not be reconfigured when demand on the NFs changes.

Abstract: Methods, devices, and systems for network slicing are provided. In one example, a method includes: selecting a first network slice and a second network slice both pertaining to a common data network, designating a first traffic flow to the first network slice and a second traffic flow to the second network slice, generating a first network slice profile including a first network identifier and first mapping information, generating a second network slice profile including a second network identifier and second mapping information, assigning the first network slice profile to the first traffic flow and the second network slice profile to the second traffic flow, and separating the first traffic flow from the second traffic flow on a user plane function (UPF) instance, based on the assigned first network slice profile and the second network slice profile.

Abstract: Various arrangements for performing grant-free uplink transmissions are presented herein. A user equipment (UE) can determine data that is to be transmitted using a grant-free uplink transmission to a base station of a cellular network. Three or more grant-free transmission blocks may be selected by the UE. The same data payload may be transmitted on each grant-free transmission block. The first grant-free transmission block can indicate the end of a chain of linked grant-free transmissions and have a pointer that references the second grant-free transmission block. The second grant-free transmission can include pointers that refer to the first grant-free transmission block and a third grant-free transmission block.

Abstract: An example system and method may manage interference to facilitate the coexistence of terrestrial and non-terrestrial wireless networks. An example system may determine frequency bands assigned to adjacent satellites or satellite services and determine an interference characteristic of the frequency bands used by the adjacent satellites. The system may select a frequency band for use by a reference satellite in a reference geographic region based on the frequency bands assigned to the adjacent satellites. In some instances, the system may instruct the reference satellite to use the selected frequency band for communication with a wireless client device in the reference geographic region.

Abstract: Embodiments are directed towards systems and methods for selecting, in a Fifth Generation (5G) cellular telecommunication network, a User Plane Function (UPF) of a plurality of UPFs on which to anchor a Protocol Data Unit (PDU) session of a new user equipment (UE) newly appearing on the cellular telecommunication network. The selection is based on: a location of the new UE; a plurality of current loads for each UPF of the plurality of UPFs; a predicted UE load of the new UE based on network data analytics; and predicted UPF loads of the plurality of UPFs as a function of time considering the predicted UE load based on network data analytics from the Network Data Analytics Function. In the UPF selection, the Session Management Function (SMF) gives higher priority to shorter term predicted loads than longer term predicted loads.

Abstract: 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.
