Abstract: Systems and methods for controlling uplink power in a non-terrestrial network (NTN). An NTN station transmits a reference signal at a first time having a defined transmission power and the reference signal is received by non-terrestrial user equipment. The user equipment evaluates the reference signal and determines a first downlink loss of the reference signal by calculating a difference between a measured power level of the received reference signal and the defined transmission power. The NTN station transmits a communication signal at a second time and is received by the user equipment, which estimates a second downlink loss of the communication signal based on the first downlink loss and a power level of the communication signal. A first uplink loss is estimated based on the second downlink loss, and the user equipment adjusts a transmission power of its transmitter based on the first uplink loss.

Abstract: Various arrangements for transitioning the bandwidth allocation of a base station are presented. Four bandwidth parts may be defined for communication with the base station. At a given time, two of these bandwidth parts may be actively used for communication by different UE for communication with the base station. In response to network traffic, a determination to adjust a bandwidth allocation may be made. A series of transitions may be performed to migrate from the first two of these bandwidth parts to the second two of the bandwidth parts such that interference does not occur.

Abstract: Various arrangements for improving cell coverage are presented. A cellular network can define a first bandwidth part and a second bandwidth part to be implemented concurrently by a base station of the cellular network. The first bandwidth part and the second bandwidth part do not overlap and may be separated by a guard band. The first bandwidth part can have a greater bandwidth and greater sub-carrier spacing than the second bandwidth part. The cellular network can determine a first set of user equipment to use the first bandwidth part for communication with the base station and a second set of user equipment to use the second bandwidth part for communication with the base station. Communication with the first set of user equipment using the first bandwidth part and the second set of user equipment using the second bandwidth part may be performed.

Abstract: Arrangements involving a multi-tenant network management system are presented. A first virtual wireless network can be operated as part of a wireless network. The first virtual wireless network can be mapped to a first set of operating level-of-service parameters. A second virtual wireless network can also be operated as part of the wireless network on behalf of a third entity. The second virtual wireless network can be mapped to a second set of level-of-service operating parameters. A traffic monitoring system may be present that monitors and compiles traffic-related statistics for the first virtual wireless network and the second virtual wireless network separately. A virtual network management system can use a machine learning arrangement to determine how to modify properties of the first virtual wireless network to satisfy the first set of level-of-service operating parameters.

Abstract: Sequential migration of network functions between old or legacy vendors and new vendors in a 5G telephone network is enabled without disruption to end-users. Network functions are migrated between control planes of network slices. A first network slice A is associated with a legacy vendor having a first set of network functions, and a second network slice B is associated with a new vendor having a second set of network functions. A gradual staged transfer of network functions originally contained in the control plane of the network slice A is migrated to the control plane of network slice B. The gradual transfer is a migration of network functions in a set of multiple stages to create the subset of the network functions in the control plane of slice B.

Abstract: 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.

Abstract: Various systems and methods for cellular network slice management are presented. A cloud-based application may be determined to be authorized to manage a cellular network slice utilized by the cloud-based application for communication with user equipment. A request can be received from the cloud-based application to modify the cellular network slice from the cloud-based application. In response to the request, a parameter of the cellular network slice may be modified. The cellular network can then use the modified slice for communication with user equipment for the cloud-based application.

Abstract: Various arrangements for performing intelligent cellular channel management are presented herein. A physical cellular communication channel may be established between a user equipment (UE) and a cellular network for sending a short message service (SMS) message in response to a cellular service request from the UE. One or more characteristics of the UE, the SMS message, or both may be analyzed. A duration of time for which the physical cellular communication channel is kept active may be based on the analyzed one or more characteristics. A channel maintenance instruction may be transmitted to keep the physical cellular communication channel active based on a cellular network messaging controller determining to adjust the duration of time for which the physical cellular communication channel is kept active.

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.
