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 arrangements for compensating for Doppler shift on a non-terrestrial orthogonal frequency division multiplex (OFDM) network are presented. A received frequency of a downlink satellite message received from a satellite may be determined. A downlink frequency delta between an expected frequency of the downlink satellite message and the received frequency of the downlink satellite message can be calculated. An uplink frequency delta based on the calculated downlink frequency delta may be calculated. An uplink transmission frequency at which an uplink OFDM symbol is transmitted may be calculated based on the calculated uplink frequency delta.

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: Various arrangements for using different air interfaces on adjacent frequency channels for side-link communications are presented. A first side-link channel may be split into a first bandwidth portion and the second bandwidth portion, in which the first bandwidth portion of the first side-link channel is directly adjacent to the second side-link channel. A first subcarrier spacing may be assigned to the first bandwidth portion of the first side-link channel. The second side-link channel may also use the first subcarrier spacing. A second subcarrier spacing may be assigned to the second bandwidth portion of the first side-link channel that differs from the first subcarrier spacing.

Abstract: Various arrangements for spectrum sharing among a terrestrial network and a non-terrestrial network are presented herein. A first bandwidth part having a first frequency range for may be assigned use for communication between one or more UE of a plurality of UE and a terrestrial cellular network when a high signal strength is present. A second bandwidth part having a second frequency range may be assigned for use for communication between one or more UE of the plurality of UE and the terrestrial cellular network when a low signal strength is present. A third bandwidth part having a third frequency range can be assigned for use for communication between one or more UE of the plurality of UE and a non-terrestrial network. The third bandwidth part can overlap with the first bandwidth part but not the second bandwidth part.

Abstract: A method and apparatus for non-terrestrial network beam switching is provided. A non-terrestrial network base station includes a transmitter configured to transmit downlink data to user equipment and a receiver configured to receive uplink data from the user equipment. A channel bandwidth of the non-terrestrial network base station is divided into a plurality of bandwidth parts respectively corresponding to a plurality of geographic areas, and each bandwidth part is respectively associated with a satellite beam. When the user equipment is located in a first geographic area, the transmitter transmits the downlink data to the user equipment over a corresponding first bandwidth part. After the user equipment transitions from the first geographic area to a second geographic area, the transmitter transmits the downlink data to the user equipment over a corresponding second bandwidth part of the plurality of bandwidth parts.

Abstract: A new radio base station establishes a first and a second component carrier in carrier aggregation. The first and second component carrier overlap each other. The base station transmits signaling and control information exclusively on the first component carrier. The base station transmits data packets on the first component carrier and on a non-overlapping portion of the second component carrier.

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 using multiple air interfaces on a frequency channel for side-link communications are presented. A first indication of a first time-window of a first resource pool may be transmitted by a first air interface system. A second indication of a second time-window of a second resource pool may be transmitted by a second air interface system. Side-link communications may be performed using the first air interface during only the first time-window of the first resource pool. Side-link communications may be performed using the second air interface during only the second time-window of the second resource pool.
