Abstract:

Aiming at multi-carrier system, a utility-based radio resource scheduling method, named as Multi-carrier gradient scheduling algorithm with minimum/maximum rate constraints (GMR) is proposed. As an extension of GMR, it can be used in beyond tree generation (3G) wireless communication system for multiuser scheduling. Analysis and simulation results show that the algorithm can provide soft quality of service (QoS) guarantee with good performance and low complexity.

Key words: beyond three generation wireless system, multi-carrier system, scheduling algorithm, utility function, soft quality of service
