We previously proposed a next generation cellular system for IMT-2000based on the Wideband DS-CDMA with TDD scheme(W-CDMA/TDD)and have evaluatedits performance by computer simulation, laboratory and field experiment. With the W-CDMA/TDD, because of its correlation between the downlink and the uplink, transmission and reception spacediversity(SD)at a base station and open-loop transmit power control(TPC)canbe simply realized. This paper reports performance of laboratory and fieldexperiments using a developed testbed. The results shows it has been confirmed that transmission and reception SDand open-loop TPC have sufficient performance under a field environment as well as laboratory environment.
