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.

Multiple concurrent bandwidth parts for a base station of a cellular network

Various arrangements for using multiple grant-free transmission configurations are presented. A cellular network may assign multiple grant-free transmission configurations to a user equipment (UE). The UE may schedule and transmit the same data using at least two separate grant-free transmission configurations.

Replicated grant-free transmissions utilizing multiple configurations

A first cellular network may connect user equipment (UE) with a data network using a first anchor point. The first cellular network may transition the UE from the first anchor point to a second anchor point. Following the transitioning, the first 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 first cellular network. The UE may be locked to the converged anchor point while the UE is communicating with a second cellular network.

Various systems and methods for scheduling data transmissions from a base station to user equipment (UE) are presented. Channel quality indicator values that correspond to multiple UE may be determined for multiple carrier components of a cellular network's carrier aggregation. A scheduling matrix may be created that includes instantaneous data transfer rates for the UE. Elements within the scheduling matrix may be normalized by modifying instantaneous data transmission rates using average data transmission rates. Scheduling decisions for data transfers may be made for the UE based on the normalized scheduling matrix.

Downlink scheduling across a cellular carrier aggregation

Various arrangements for performing grant-free uplink transmissions are presented herein. A user equipment (UE) can determine data that is to be transmitted using a grant-free uplink transmission to a base station of a cellular network. Three or more grant-free transmission blocks may be selected by the UE. The same data payload may be transmitted on each grant-free transmission block. The first grant-free transmission block can indicate the end of a chain of linked grant-free transmissions and have a pointer that references the second grant-free transmission block. The second grant-free transmission can include pointers that refer to the first grant-free transmission block and a third grant-free transmission block.

Robust grant-free transmissions

Systems and methods manage data traffic by converging a mobile network operator (MNO) core network with a multiple-system operator (MSO) core network (e.g., a Hybrid-Mobile Virtual Network Operator (H-MVNO) core network). The system architecture includes one or more standards-based inter-network interfaces (e.g., as defined by Third Generation Partnership Project (3GPP) standards) established between the MSO core network and the MNO core network and/or a dedicated core to provide a data signal pathway between the MNO core network and the MSO core network. As such, a user equipment (UE) receives data services through the H-MVNO core network via the standards-based inter-network interface when the UE is connected to a radio access network (RAN) for the MNO core network. Various configurations provide data services for single-subscriber identity module (SIM) UEs and dual-SIM UEs. Voice/message services are provided by a voice/message core.

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.

Various arrangements are presented for using an estimated timing advance for user equipment communications. A location of an instance of user equipment may be determined. An estimated distance between the user equipment and a communication satellite may be determined using the determined location of the user equipment and an estimated satellite location. An estimated timing offset using the calculated estimated distance may be determined. An uplink data frame may be transmitted by the user equipment to the satellite such that a timing of transmission of the uplink data frame is based on the calculated estimated timing offset.

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.

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

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.

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.

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.
