Abstract

This document discloses a solution for scheduling resources in a network using split frequency domain scheduling and time domain scheduling. According to an embodiment, a method for a frequency-domain scheduler comprises: receiving, by the frequency-domain scheduler from a first time domain scheduler employing a first scheduling policy to schedule time domain resources, a first scheduling request comprising a first priority indicator; receiving, by the frequency-domain scheduler from a second time domain scheduler employing a second scheduling policy different from the first scheduling policy, a second scheduling request comprising a second priority indicator provided on the same scale as the first priority indicator; and scheduling, by the frequency-domain scheduler, frequency domain resources to the first time domain scheduler and the second time domain scheduler on the basis of the first priority indicator and the second priority indicator.
