Overview: The 3rd Generation Partnership Project (3GPP) is a standardization body for 3G mobile radio systems known as the Universal Mobile Telecommunication System (UMTS). The 3GPP recommends using Wideband Code Division Multiple Access (WCDMA) for UTRA FDD and Time Division Code Division Multiple Access (TD-CDMA) for UTRA TDD. In addition, the 3GPP also recommends the Time Division Synchronous Code Division Multiple Access (TD-SCDMA) for TDD applications. This white paper describes the basic characteristics of the UTRA TDD and UTRA FDD modes, as specified by the 3GPP. It also highlights the differences and commonalities between the two modes.
