This paper focuses on a transitional scenario such that FDD channels in existing system inducing large downlink traffic is successively replaced by TDD channels in order to cope with the increased downlink traffic. Since the existing FDD channels are replaced by TDD channels, no additional channels and no overall system update are required in this scenario. In other words, the proposed scenario is suitable to those who employ the current FDD based 3G standard, e.g. WCDMA and CDMA2000. Investment cost may be small because transition from FDD to TDD channels would be done by only minimum modification. Performance of the proposed adaptive duplex method is evaluated and compared with a system homogenously occupied by FDD.
