Power Control and Radio Resource Management in Wireless Multimedia Personal Communication Systems

The scarce radio spectrum imposes hard limitations on designing cellular radio systems. To provide high-capacity communication services, powerful methods for sharing the radio spectrum in the most efficient way are required. In practice, all sharing methods introduce some form of interference, which is proportional to the transmitter powers. For voice services, transmitter power control has shown to be an essential technique that can improve performance by balancing the signal and interference powers. As the demand for wireless data increases, resource allocation for providing diverse quality of service (QoS) requirements is of interest. Since the characteristics of such services differ from voice services, new transmission schemes need to be investigated. In this project we focus on power controlled transmission schemes that should be able to conserve energy as well as supporting the QoS needed. To support delay insensitive non-real time data service, data rates need to be controlled. Therefore, joint control of transmitter powers and data rates is considered as well as schemes for transmission scheduling.

The international research partner is KTH. The project is funded by the Academy of Finland and Vinnova (EXITE program).
