Abstract:
1. A method of ranking-based scheduling of multiple users on a shared communication channel of a serving base station in a wireless communication system, wherein said users are divided into a number of traffic classes, wherein each traffic class is associated with a predetermined target bandwidth share, and wherein the relation between the target bandwidth shares of different traffic classes are expressed as target bandwidth share ratios, said method comprising: determining, for each user of a given traffic class, measured bandwidth share ratios with respect to an average rate of users of each of a number of other traffic classes; determining, for each user, a priority rank based on an achievable bit rate of the user according to a reported channel quality and a quality of service component representing compliance of the measured bandwidth share ratios to the target bandwidth share ratios; selecting a subset of said users among those users having the highest priority ranks; and allocating transmission resources of said base station to the selected subset of said users for transmission of user data on the shared communication channel.
