Capacity and Coverage Analyses for Group Cell with Weighted Transmission Power Allocation Scheme
采用发送功率加权分配策略的群小区架构容量与覆盖分析

With the increasing demand for high data rate and high quality of mobile telecommunication services, and the deeply research on multi-antenna techniques, the cellular concept and network topology for future mobile communication systems are necessarily researched. This paper introduces the generalized distributed cellular architecture-group cell, which is suitable for advanced physical techniques and solves the problem of smaller cells caused by higher frequency carrier. The concept and the structure of the group cell are described and slide handover strategy based on the group cell is introduced as well. The system performance of capacity and coverage with downlink weighted transmission power allocation scheme are focused both in theory and numerical simulation. Compared to traditional cellular structure, the simulation results verify that group cell architecture can improve the system capacity and enlarge the coverage area.
