Dynamic 5G network slicing to maximize spectrum utilization

One or more hardware-based non-transitory computer-readable memory devices storing computer-executable instructions which, upon execution by one or more processor disposed in a computing device, cause the computing device to:

• provide a channel state information (CSI) prediction model to predict CSI for user equipment (UE) connecting to a 5G (fifth generation) network over an air interface that is established between the UE and a radio unit (RU), in which the 5G network comprises a plurality of slices;
• use the predicted CSI to identify physical radio resources to allocate to a slice among the plurality to transmit data from the RU to the UE, in which the physical radio resources comprise a combination of a radio channel subcarrier selected from among a plurality of different subcarriers and a time slot in radio frames selected from among a plurality of different time slots;
• and
• schedule data transmissions for the slice using the identified physical radio resources based on the predicted CSI to maximize throughput for the slice over the air interface.

A computing device, comprising:

• at least one processor;
• and
• at least one hardware-based non-transitory computer-readable storage device having computer-executable instructions stored thereon which, when executed by the least one processor, cause the computing device to
• dynamically operate a radio access network (RAN) in a 5G (fifth generation) network by collecting channel state information (CSI) data in response to changing conditions on the 5G network applicable to current data transmissions over slices of an air interface established between user equipment (UE) and a radio unit (RU) in the 5G network, in which the 5G network comprises a plurality of slices that are respectively associated with the slices of the air interface;
• use the collected CSI data to generate predicted CSI for future data transmissions over the slices of the air interface;
• select a combination of subcarrier and time slot for each of the future data transmissions using the predicted CSI;
• and
• schedule the future data transmissions on the slices of the air interface using the selected combination of subcarrier and time slot.
