Scheduling in a Communication Network

A scheduler for allocating communication resources to terminals that are operating in a communication network comprising a plurality of cells, the scheduler comprising a macro-scheduler configured to, for the plurality of cells, allocate the communication resources available to each cell between the terminals in that cell using a first scheduling algorithm and a micro-scheduler configured to allocate the communication resources available to one of the cells between the terminals in that cell using: (i) the macro-scheduler's allocation of communication resources between those terminals; and (ii) a second scheduling algorithm.
