SCHEDULING IN CELLULAR COMMUNICATION SYSTEMS

摘要

A method for scheduling enhanced uplink traffic in a cell in a cellular communication system comprises estimating of a rise-over-thermal measure for the cell. A momentary total load in the cell is computed based on the estimated rise-over-thermal measure. A load headroom is determined from at least a maximum allowed load and the momentary load. Future enhanced uplink traffic is scheduled in dependence of the determined load headroom. A degree of underutilization of enhanced uplink traffic grants in the cell is established. The scheduling comprises overbooking of enhanced uplink traffic in dependence on the established underutilization degree. A network node comprises corresponding functionalities.

1. A method for scheduling enhanced uplink traffic in a cell in a cellular communication system, comprising the steps of:
estimating a rise-over-thermal measure for said cell; computing a momentary total load in said cell based on said estimated rise-over-thermal measure; determining a load headroom from at least a maximum allowed load and said momentary load; scheduling future enhanced uplink traffic in dependence of said determined load headroom; and establishing a degree of underutilization of enhanced uplink traffic grants in said cell; wherein said step of scheduling comprises overbooking of enhanced uplink traffic in dependence on said established underutilization degree; wherein the method steps are performed by a network node.
