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: 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 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: 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 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 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.
