Doctoral dissertation: Enhanced cellular networks by inter-user communication
19.01.2012
M.Sc. Chia-Hao Yu's doctoral dissertation examines inter-user communication in cellular networks. Inter-user communication refers to a situation where a mobile phone does not connect to a base station, but uses other nearby mobile phones when the user attempts to make a call or upload data to other user. Yu's research resulted in methods that can help to find the most cooperative mobile phones nearby. He also developed methods that help mobile phones to share frequency resources in an efficient way.
Wireless data transfer is developing towards seamless coverage with increasingly high data transfer rates. However, the situation is challenging due to the limited transmit powers and congested radio spectrum. Inter-user data transfer can improve the coverage of the service and create a more uniform service quality by allowing cooperation between cellular phones in certain areas. The direct transfer of data between mobile phones would also enable a more efficient use of frequency resources when advanced radio resource management methods are being used.
M.Sc. Chia-Hao Yu's doctoral dissertation "Radio Resource Management for Cellular Networks Enhanced by Inter-User Communication" will be publicly examined at 12 noon on 27 January 2012 at the Aalto University School of Electrical Engineering in lecture hall S1 (Otakaari 5 A, Espoo).
