This book is an outgrowth of the pioneering development work done by InterDigital Com-
munication Corporation in 3rd Generation tdd WCDMA Technology. Many engineers
and managers were involved in this development, which spanned a wide range of tech-
nology areas, including system architecture, radio interface, radio modem design, radio
resource management and hardware/software implementation. In addition, tdd WCDMA
technology had many direct and indirect contributors across the globe in the context of
the development of the 3GPP tdd WCDMA Standard.
