A Two-Step Scheduler for Dynamically Sharing Wireless Channel Resources among Operators

Sharing wireless channel resources among cellular network operators saves costs by efficiently utilizing hardware and spectrum. We introduce a practical scheduler that (i) allocates time slots among operators in a round robin manner and (ii) allocates resources to the users of each operator. This two-step approach guarantees the agreed resource shares while allowing each operator to execute its own multi-user scheduling policy. Our simulation results demonstrate an insignificant increase in delay at high spectral efficiency and fairness.
