Group cells and slide handover mode

Abstract

For the third generation systems' low frequency efficiency and small system capacity, there should be greatly changed in physical techniques in fourth generation mobile communication systems while many advanced techniques suited for high bit rate, high frequency efficiency and large dynamic range, such as JT, STC, MIMO, OFDMA, distributed antenna, are taken into considerations. But besides physical techniques, basic network layer techniques, e.g., the constructions of cellular and the modes of handover, must be broken through in the fourth generation mobile communication systems. The group cell structure proposed in WTI is a novel cellular construction method, which is fit well for these new advanced physical techniques. And slide handover is also novel handover mode emphasized in this paper. According to the current research, the slide handover could improve the system capacity dynamically.
