TDD slot format selection service
A method, a device, and a non-transitory storage medium are described in which a TDD slot format selection service is provided. The service may calculate a distance between a radio access network device and an end device and use the distance to select a TDD configuration for the end device. The service may use other criteria to select the TDD configuration such as downlink or uplink ratios and/or interference value pertaining to a neighboring radio access network device. The service may also include scheduling of traffic adjustments based on a determined traffic bias associated with the end device and slot format symbols.
