Scheduling in a communication network

Communication resources are allocated to terminals operating in a communication network comprising a plurality of cells. A macro-scheduler allocates 201, for the plurality of cells, the communication resources available to each cell between the terminals in that cell using a first scheduling algorithm. A micro-scheduler allocates 203 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. The macro-scheduler may designate an allocation of communication resources to a terminal as mandatory or suggested such that the micro-scheduler always implements an allocation designated as mandatory and optionally implements an allocation designated as suggested. The implementation of a suggested allocation may be in dependence on the second scheduling algorithm and may not be implemented if the micro-scheduler determines that not implementing it is likely to increase performance across the one of the cells.
