The system receives orbital information for at least one satellite of a non-terrestrial network. The orbital information includes the location and velocity of the at least one satellite. The system determines a location of a wireless device and the wireless device's location relative to the at least one satellite. The system calculates a connectivity window based on the relative location. The connectivity window is a time period at the location of the wireless device during which the wireless device receives a signal from the at least one satellite to perform a network connection with the non-terrestrial network. The system connects the wireless device to the non-terrestrial network when the connectivity window of the at least one satellite is open. The system prevents the wireless device from searching for a network connection to the non-terrestrial network when the wireless device is outside the connectivity window of the at least one satellite.

Various systems, methods, and devices relate to determining a delay associated with a device; calculating a guard time based at least in part on the delay; and scheduling a wireless resource to include a downlink interval, an uplink interval, and the guard time between the downlink interval and the uplink interval. By calculating the guard time based at least in part on the delay associated with the device, spectrum efficiency can be enhanced, and latency can be reduced.

Systems and methods to enhance spectrum efficiency and to reduce latency by using dynamic guard time selection in wireless systems

A base station can select orthogonal frequency-division multiplexing (OFDM) numerologies that define subcarrier spacing values based on attributes associated with one or more services that a user equipment (UE) is using. The base station can use the selected OFDM numerologies for transmission associated with the services. When the UE is using multiple services simultaneously, the base station can select the same or different OFDM numerologies for the multiple services.

Dynamic numerology based on services

Systems, methods, and apparatuses may comprise a Radio Access Network (RAN) node for performing RAN-layer network slicing. The system may comprise a User Equipment (UE) in communication with the RAN node to provide the UE access to a core network (e.g., a 3rd Generation Partnership Project (3GPP) 5G network). The core network may comprise one or more Network Functions (NF) including an Access and Mobility Management Function (AMF) for facilitating communications between the RAN node and other NFs. By sending one or more RAN node messages and/or AMF messages, the system may perform RAN-layer slicing to register the UE with a network slice, establish a PDU session for the UE with the network slice, and/or provide a service to the UE with the network slice. In some instances, RAN-layer network slicing may be performed for multiple, specific use cases to meet UE service requirements.

Network slicing with a radio access network node

A location for application processing is selected based on latency measurements associated with a mobile network. Instead of performing application processing at a predetermined location within a network, the application processing for an application is located within the network based on latencies measured within the network as well as other considerations. For instance, the determination of the location within the network can be based on latency measurements, target latency specifications of an application, the availability of computing resources at a location, and the like. A latency aware routing controller selects one or more locations to perform application processing. The locations may include computing resources located at or near the wireless base station (BS), between the base station and other locations within the network, at the core network, at the Internet, and/or at other locations to provide applications with the computing resources to perform the application processing.

Network latency aware mobile edge computing routing

A first access node of a first wireless access network receives, via a first entry node of the first network, a service-request message from a terminal registered with the first network. The first access node requests first network-capacity information associated with the first wireless access network from the first entry node, and second network-capacity information associated with a second wireless access network from a second access node of the second network. The first access node selects a target access network based on the service-request message and the first and second network-capacity information. The first access node, in response to a selection of the first wireless access network, sends a service-reply message to the first entry node. The first access node, in response to a selection of the second wireless access network, triggers a handover of the terminal to the second wireless access network.

Triggering terminal handover after session-request message

Techniques for detecting and/or mitigating interference in a wireless network are discussed herein. An environment may include a base station in communication with one or more user equipment (UE) and one or more microwave backhaul transceivers. In some examples, the base station may and transceivers may communicate using frequencies in the same band (e.g., a millimeter frequency band). A geometry of devices in an environment can be determined. Further, interference can be detected based on a flexible portion of a transmission or a source identifier that can be included in a transmission. In some examples, the microwave backhaul transceivers may communicate via a same or similar millimeter frequency resources. Wireless resource(s) can be selected or otherwise determined for one or more components of the network to mitigate interference in the network.

Mitigating interference between base stations and microwave backhaul transceivers

A computing system may utilize interfering signals of two or more wireless devices for improving communications involving the two or more wireless devices. These techniques and architectures may allow for improved spectral efficiency that enables a relatively large number of wireless devices to communicate among one another via receivers that share overlapping or adjacent frequencies. Such utilization of interfering signals may help solve a general problem involving, for example, co-channel interference (CCI) arising from densely deployed relatively small wireless communication cells for increasing communication throughput.

Increasing wireless spectral efficiency by leveraging interfering signals

A communication cell may receive a request to establish a communication session for delivery to a core network of carrier network, the request originating from a user device connected to the communication cell. A lookup table stored in the communication cell is populated with an association of a session identifier assigned to the communication session and a caller identifier of the user device. The request is placed into an uplink buffer portion of the communication cell that is set aside for the user device. The request is encoded into one or more physical resource blocks reserved for the communication cell by a macrocell, the physical resource blocks being a part of a wireless in-band backhaul between the communication cell and the macrocell. The one or more physical resource blocks that include the request from the communication cell are then transmitted to the macrocell for delivery to the core network.
