CDMAセルラシステムにおけるマクロ/マイクロセル統合に関する検討

概要

The optimizing CDMA cellular system should account for both maximizing the capacity which implied a small cell size and minimizing the network control associated with handover. We consider the system architecture with two tiers of cells, microcell and macrocell. The low-mobility users, e.g. pedestrians, allow to operate in microcell environment while the high-mobility users, e.g. users in moving car or bus, must operate in macrocell layer in order to keep the network control low. One of the major challenges arises from the objective of serving both low- and high-mobility user populations within an integraded system(microcell/macrocell). The concept of distributed antenna, recently, was chosen to replace the large macrocell antenna with a set of many microcell antennas. In this report we studied the performance of the system in which the macrocell antenna is replaced by a microcell group set.
