A Resource Allocation Scheme for QoS Provision in Multi-beam Mobile Satellite Communication Systems

To develop large capacity high quality mobile satellite communication systems in the future, a multi-beam that can cope with extremely high levels of frequency reuse must be used. We describe a novel resource allocation scheme that enables systems to contend with ever-changing user distribution and inter-beam interference conditions. The proposed scheme simultaneously controls various kinds of radio resources, such as transmission power, frequency bandwidth, and modulation parameters. It adapts them to each user depending on the radio propagation environment. Our performance evaluations demonstrate that the scheme can satisfactorily allocate multi-beam satellite resources to greatly increase communication capacity and still improve the communication quality, thus ensuring QoS under various user distribution and traffic conditions.
