I. INTRODUCTION
The rapid growth of wireless networks and services,
accelerated by the third-generation mobile a m -
munication system (in shon hereafter, 3G system)
research, is ushering in the era of the fourth-generation
mobile communication system. Wireless Communication
systems are evolving to meet the ultimate goal, to
allow ‘anywhere, anyime, anything, by anyone’ communication
customized to a particular subsaiber’s
preferences, location, and social behavior. To reach this
gcal, much effort is still undenvay.
From 1997, the 3G standards have teen primarily
driven by two international standardization organiralions
- 3GPP (Third Generation Partnership Project)
and 3GPPZ [I-31. The 3GPP and 3GPP2 have made
cwrdination and harmonization efforts aiming af a
global MT-2000 system. The 3GPP developed a standard
based on WCDMA (wideband code division multiple
access) and GSM-MAP, while the 3GPP2 established
a standard bared on cdma2000 and ANSI
(AmericanNational Standards Institute) - 41.
Although the 3G system is designed to support
data rates up to ZMbps, it is hard to provide such a
speed to every single user in each cell. Also, highly
demanded is the unified provision of various kinds of
services including the ones provided by systems such
POTS (plain old telephone system), LAN (local area
network), xDSL (digital subscriber line, x: S (symmetric),
A (asymmetric), V (very high-speed), H (highspeed)),
and 3G systems [4,5].
In order to acwmmcdate new needs of the subscribers,
a great many efforts on a new wireless system
(hereafter, we call it 4G system) are being made in
many countries and organizations including J a m
U.S.4 and ETSI (European Telecommunication Standards
Institute).
In this paper, we propose terminal implementation
technology. The focus of the paper is to define and
identify what the mobile terminal will be in the 4G
system.
