A new cell structure for distributed wireless communication system without inter-cell interference

Distributed wireless communication system (DWCS) is one of the candidate architectures for future mobile communication system. In this paper, based on the TDD DWCS, a new cell structure is proposed with universal frequency reuse. In the proposed structure, the cells are divided into 2 groups, and when one group is in the uplink period, the other transmits the downlink data. All the base station share the whole frequency spectrum. By use of the advantage of the distributed processors, the inter-cell interference in the uplink of a cell can be perfectly removed. As to the downlink, the inter-cell interference can also be avoided by proper resource allocation among mobile users. With universal frequency reuse and without the inter-cell interference, simulation results show that DWCS with the proposed structure has an extremely high capacity
