Systems, methods, and devices can be utilized to schedule at least one Hybrid Automatic Repeat Request (HARQ) transmission and at least one HARQ feedback message in the same Physical Resource Block (PRB). A HARQ transmission can be scheduled in a mini-slot of the PRB. Accordingly, latencies associated with transmitting and receiving the PRB can be reduced, while the high reliability of HARQ can be retained. Implementations can be applied to 5G technologies such as Ultra Reliable Low Latency Communications (URLLCs) and enhanced Mobile BroadBand (eMBB), as well as other low-latency communications. A method can include determining a location of a device; selecting, based at least in part on the location of the device, a mini-slot size; scheduling, in one or more mini-slots having the mini-slot size in a PRB, a HARQ transmission; and transmitting, to the device, the HARQ transmission in the one or more mini-slots of the PRB.

Scheduling HARQ transmissions in mini-slots

A slice manager associated with a network access point of a telecommunication network can manage combinations of network slices and bandwidth parts for user equipment (UE). The bandwidth parts can have independently set numerologies, such as subcarrier spacing values. The UE can be configured to use one or more active bandwidth parts at a time, such that the slice manager can instruct the UE to use multiple active bandwidth parts simultaneously with respect to the same network slice or multiple network slices.

Bandwidth part configuration for network slicing

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

A real-time slice manager at a base station of a telecommunication network can manage radio resources allocated to network slices. The real-time slice manager can receive input factors associated with one or more network slices, including loading information, latency information, radio conditions, and other input factors. If the real-time slice manager determines that a network slice is not meeting a goal, such as a goal defined in a Service Level Agreement (SLA), the real-time slice manager can locally adjust radio resources allocated to one or more network slices, and/or treatment of network slices in a transport link or core network, to increase the likelihood that the network slice will meet the goal. The real-time slice manager can thus dynamically manage network slices at the base station to efficiently use available radio resources, manage network functions in the core network and/or transport link, and meet goals for the network slices.

Base station radio resource management for network slices

A latency manager at a base station in a radio access network (RAN) can be configured to dynamically determine an end-to-end latency associated with an end-to-end connection for a UE that extends through the RAN, a transport network, and a core network. The latency manager can also dynamically determine whether the end-to-end latency meets an end-to-end latency goal associated with the end-to-end connection. If the end-to-end latency does not meet the end-to-end latency goal, the latency manager can cause the base station to dynamically adjust radio resources to lower a RAN latency associated with the end-to-end connection. Lowering the RAN latency can cause the overall end-to-end latency to be lowered and to meet the end-to-end latency goal. In some examples, the latency manager may also request that the transport network and/or the core network take actions to reduce latencies to reduce the end-to-end latency to meet the end-to-end latency goal.

Base station management of end-to-end network latency

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.

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 telecommunications network may adjust service (e.g., data rate) to UE devices within an adjustable zone (AZ) that includes at least two types of coverage (e.g., 4G and 5G), depending on services being utilized by the UE devices and current network conditions of the telecommunications network. When a UE device enters the AZ, the services utilized by the UE device are determined. For instance, if the UE device is moving within the AZ, and the LTE is congested, the data rate for the device may be reduced. If the LTE network is not in a heavy loaded condition and the UE device is utilizing an Enhanced Mobile Broadband (EMBB) service, the AZ can be reduced or disabled. Further, the device data rate can be reduced for different services in the AZ to keep more devices in NR coverage.

Service-based data rate control to enhance network performance

Systems, methods, and devices can be utilized to schedule at least one Hybrid Automatic Repeat Request (HARQ) transmission and at least one HARQ feedback message in the same Physical Resource Block (PRB). A HARQ transmission can be scheduled in a mini-slot of the PRB. Accordingly, latencies associated with transmitting and receiving the PRB can be reduced, while the high reliability of HARQ can be retained. Implementations can be applied to 5G technologies such as Ultra Reliable Low Latency Communications (URLLCs) and enhanced Mobile BroadBand (eMBB), as well as other low-latency communications. A method can include detecting a fading condition of a device; scheduling, in one or more mini-slots of a PRB, a HARQ transmission based at least in part on the fading condition; and transmitting, to the device, the HARQ transmission in the one or more mini-slots of the PRB.
