Asymmetric Traffic Accommodation Using Dowlink Multihop Transmission in CDMA/FDD Cellular Systems

Abstract (in Japanese) (See Japanese page) 
(in English) The asymmetric traffic between uplink and downlink over recent mobile communication systems has been becoming conspicuous because of providing new communication services.
This paper proposes a novel CDMA/FDD cellular packet communication system using a multihop transmission technique to accommodate asymmetric traffic efficiently for the FDD based cellular systems.
The proposed system exploits the multihop transmission for downlink packet transmissions which require the large transmission power at their single-hop transmissions in order to increase the downlink capacity.
In these multihop transmissions, the uplink band is used for the transmissions from relay stations to destination mobile stations, and this leads more capacity enhancement in the dwonlink communications.
The proposed system is evaluated by computer simulation and the results show that the proposed system can achieve better system performance than the convetinal CDMA/FDD system.
