“…In the past decade, the adaptive antennas have been proposed to improve the spectrum efficiency and provide a new approach to the next-generation networks, which have been considered as one of most important technologies in the wireless communications [15][16][17][18]. By adopting the basestation adaptive antenna technology [19][20][21], intelligent cell with adaptive array antennas was proposed [22][23][24]. On the one hand, the beam can be split or the multibeam method can be adopted to reduce the influence caused by the radio propagation environment, which leads to the improved channel quality and the enhanced system capacity.…”

Different from the traditional configuration of hierarchical cellular, we introduce the joint base-station multi-antenna multi-beam and channel assignment scheme for hierarchical cellular in this paper. The proposed scheme is based on multi-beam base-station antenna splitting in the elevation-radiating plane, and a dynamic channel allocation scheme by combining the adaptive antenna technologies. Simulation results show that the proposed configuration of the hierarchical cellular can enhance the spectral efficiency remarkably.

9-1. Hatchobori 2Chome, Chuo-ku. Tokyo, 104-0032 Japan Abstracf-This paper studies a downlink antenna weight control method of adaptive array antenna at the base station in FDDIW-CDMA systems based on the location information of both the direction of arrival (DOA) and the distance between base station and mobile unit. We introduce a power weight function added to transmitter power according lo the distance from BS in order to improve CIR of users far from BS laking a multi-cell system environment into account. And we clarify that our proposed method is very efleetive to increase the user's capacity in the downlink far a multi-cell system.
