Abstract The increasing demand for capacity in order to provide high data rate multimedia services in wireless environments necessitates enhanced radio transmission techniques and network protocol functionality. Such techniques have to be added to already existing mobile cellular networks, e.g. as provided by EDGE. For 3rd generation UMTS networks based on WCDMA, the High Speed Downlink Packet Access (HSDPA) is being introduced to meet this demand and improve spectral efficiency. This technique is based on well-known Link Adaptation (LA) by using various modulation and coding schemes and with this realizing several different data rates for downlink transmission. Moreover, fast scheduling techniques are introduced to enable efficient and flexible sharing of the radio resources among different users and services. This paper gives a detailed overview of the iintegration of HSDPA in UMTS networks and provides a performance evaluation with respect to a multi-cellular environment with various types of applications. The question whether LA mechanisms are beneficial in a WCDMA system is discussed and advice to the network dimensioning is given.
