In this paper, we consider the throughput performance in relay-aided multi-cell orthogonal frequency division multiple access (OFDMA) system, when mobile user (MS) is uniformly distributed and relay station (RS) is located at some typical positions, such as dRS = 0:5 and dRS = 0:85, where dRS is the ratio between the distance from RS to base station (BS) and the cell radius. Although cooperative diversity...
Mobile cellular networks are now largely deployed, and mobile customers are used to place and to receive calls at any location. The network coverage is continuous, but radio conditions met by users are not homogeneous. Thus, data rate is varying according to user mobility. In this paper, we propose to discriminate terminals by their radio conditions in order to select which data has to be sent. More...
This paper presents the architecture and functional model of cooperative radio resource management (Co-RRM) for the efficient integration of different radio access technologies. The cooperative management mechanism and procedure is designed and the policy-based network resource allocation algorithm is introduced to keep mobile users always best connected. In order to optimize the resource utilization,...
