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: Systems and methods of scheduling bit rates for first-class traffic for a first and second class session for a device; honoring for the device each first class session with the bit rate equal to a session aggregate maximum bit rate (AMBR) by a scheduler by assigning a threshold for an aggregate bit rate for traffic for each first-class session; if a total of the aggregate bit rate of traffic for each first class session is below the threshold assigned, then assigning each first class session the session AMBR for first-class session traffic for the device; if the total of the aggregate bit rate of traffic for each first class session is above the threshold assigned, then proportionality scheduling packets of the traffic for the first class session of the device to limit the aggregate rate of the first-class traffic below the threshold.

Abstract: Various arrangement of compound cellular networks that accommodate multiple cellular communication protocols are presented. A compound cellular network may connect user equipment (UE) with a data network using a first anchor point. The compound cellular network may transition the UE from the first anchor point to a second anchor point. Following the transitioning, the compound 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 compound cellular network. The UE may be locked to the converged anchor point while the UE is communicating with a second cellular network that communicates using the second cellular communication protocol.

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 using multiple grant-free transmission configurations are presented. A cellular network may assign multiple grant-free transmission configurations to an instance of user equipment. The cellular network may receive a set of data according to the first grant-free transmission configuration and a replication of the set of data according to the second grant-free transmission configuration.

Abstract: Various arrangements for performing uplink grant-free transmissions are presented herein. An instance of user equipment (UE) may determine data that is to be transmitted using a grant-free (GF) uplink transmission to a base station of a cellular network. The UE may select a first GF resource block and a second GF resource block. The UE may transmit a GF transmission that comprises a data payload and a first pointer at the first GF resource block. The first pointer may refer to the second GF resource block.

Abstract: Various arrangements for compensating for Doppler shift on a non-terrestrial orthogonal frequency division multiplex (OFDM) network are presented. An absolute location of the UE instance may be determined. A relative velocity of the UE instance with respect to a satellite of the non-terrestrial OFDM network may be determined. A frequency delta due to Doppler shift may be determined. A transmission frequency at which an uplink OFDM symbol is to be transmitted to the satellite of the non-terrestrial OFDM network may be determined using the frequency delta.

Abstract: A method and apparatus for prediction-based non-terrestrial network beam configuration and switching are provided. A base station determines a bandwidth part configuration for a user equipment, which includes a plurality of bandwidth parts respectively corresponding to a plurality of geographic areas. The base station configures the user equipment with the bandwidth part configuration and determines a position or movement of the user equipment in a first geographic area corresponding to a first bandwidth part. The base station determines, based on the position or movement, whether a criterion for reconfiguring the bandwidth part configuration is met. In response to determining that the criterion is met, the base station reconfigures the bandwidth part configuration of the user equipment while the user equipment is positioned in the first geographic area. The reconfiguration includes modifying the plurality of bandwidth parts to include a second bandwidth part corresponding to a second geographic area.

Abstract: A system and method for managing interference between different enterprises operating over the same spectrum. The system includes a central unit of a first enterprise associated with a first cell site; a central unit of a second enterprise associated with a second cell site; and an interface for connecting the central unit of the first enterprise to the central unit of the second enterprise and configured to transmit load information; wherein a central unit of either enterprise is configured to share load information without requiring a standard form between each enterprise via the interface to minimize interference between each enterprise when both enterprises are operating in the same spectrum and an overlapping coverage region between each cell site.
