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: Spectrum and radio resources associated with a 5G radio unit (RU) of a host network are dynamically allocated amongst one or more guest networks. A provisioning plane receives inputs from a guest network operator that identifies desired times, locations and/or frequency bands for desired network coverage. The provisioning plane responsively identifies bandwidth allocations that meet the requested parameters for exclusive use by the guest network. User equipment (UE) associated with each guest network maintains time and frequency synchronization with the host network, but otherwise limits its communications to the frequency bands allocated to the guest network. By dynamically obtaining physical radio and spectrum resources from a host provider and by scaling backend network capabilities using cloud resources, guest networks for any number of different purposes can be quickly deployed or modified as desired.

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.

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.

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 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 GF transmissions that comprise: a data payload and a first pointer at the first GF resource block; and the data payload and a second pointer at the second GF resource block. The first pointer may refer to the second GF resource block, while the second pointer may refer to the first GP resource block.

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 to be 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 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.
