1. A radio base station comprising: a first interface for receiving downlink data packets from a core network; a second interface for transmitting data packets to user entities; a processor further comprising: a scheduler; a first memory partition comprising for storing, parameter data pertaining to a first subset of allocated priority queues; a second memory partition for storing parameter data pertaining to a second subset of allocated priority queues, whereby the processor is configured to transfer parameter data between the first memory partition and second memory partitions partition, and vice versa; whereby parameter data for priority queues having no data packets in corresponding buffers is prioritized for being transferred to the first memory partition, parameter data for priority queues having data packets in corresponding buffers is prioritized for being transferred to the second memory partition, the processor configured to perform scheduling based on a selection of priority queues whose parameter data is residing in the second memory partition.
