Abstract: In a method of scheduling transmission services over a high speed packet access communication link such as a HSDPA and/or a HSUPA link a list of queues is created for transmission services to be provided over the link. The queues, which include both Real Time and Non Real Time queues, are allotted respective service priorities based e.g. on a channel quality indicator and/or a Quality of Service indicator to produce an ordered list of queues based on the service priorities. The link resources needed for serving at least one set of queues having higher priorities in the ordered list are estimated and a check is made. If these resources are available, the set of queues having higher priorities in the ordered list are served. If the resources required are not available, at least one queue is removed from the ordered list of queues.
