For the planning and deployment of the 3.5G enhancement of UMTS, the High Speed Downlink Packet Access, mobile telecommunication providers need to estimate the signal-to-interference-ratio of the HSDPA users. Although the received signal power is easy to calculate due the channel adaptive principle of HSDPA, the received interference includes the signal powers of the power controlled dedicated channel users and is therefore more challenging. Our contribution is a semi-analytical method to calculate the spatial distribution of the received interference. The method considers the interference generated in the own cell and in the surrounding cells including the load dependent interference coming from the dedicated channel users.
