B3G Mobile Communication System
Abstract:This article introduces the visions and developments of Beyond 3G (B3G) mobile communications systems in Wireless Technology Innovation (WTI) Lab, BUPT. All IP System structure, radio transmission design, cell structure, radio resource management and demonstration system implementation are covered. The concept of group cell and the architecture of distributed antennas are introduced. The radio link transmission design presented in this article includes the radio frame structure, multiple access scheme, and promising key techniques. Link-level simulations prove the advantages of the design. The radio resource management strategies are introduced to optimize the system performance. The B3G TDD demonstration system developed in WTI is also shown to evaluate the B3G TDD design.
Keywords: Beyond 3G, Mobile Communication System, Group Cell, Radio Resource Management
