Abstract

Systems and methods for radio resource allocation across multiple resource dimensions are disclosed. In some embodiments, a method of operation of a network node in a wireless communications network to allocate one or more radio resources to two or more traffic partitions includes obtaining radio resource allocation policies for the two or more traffic partitions; obtaining radio resource usage for the two or more traffic partitions across multiple resource dimensions; and allocating the radio resources to the two or more traffic partitions based on the radio resource usage of the two or more traffic partitions across the multiple resource dimensions and the radio resource allocation policies for the two or more traffic partitions. In this way, the radio resource allocation policies may be enforced across multiple resource dimensions of the wireless communications network.
