A METHOD AND A NETWORK NODE FOR IMPROVING RADIO RESOURCE UTILIZATION IN A WIRELESS COMMUNICATION NETWORK

摘要

Disclosed is a method performed by a network node (120) in a wireless communication network (100), for improving radio resource utilization of wireless radio resources provided by the network node. The method comprises obtaining, for each of a plurality of mobile stations (101, 102, 103) wirelessly connected to the network node (120), a channel quality describing a quality of a radio channel connecting the one of the plurality of mobile stations to the network node, a channel bandwidth of the radio channel connecting the one of the plurality of mobile stations to the network node, and a measure of an amount of data to communicate between the one of the plurality of mobile stations and the network node. The method further comprises determining a communication time need for each of the plurality of mobile stations based on the obtained channel quality, the obtained channel bandwidth and the obtained measure of amount of data to communicate for each respective mobile station, grouping the plurality of mobile stations into one or more subgroups based on their respective determined communication time need, and allocating transmission time to each of the one or more subgroups based on the determined time need.
