Downlink dimensioning for the HSDPA standard
Dan Avidor, Sayandev Mukherjee · 2003
We present an analytic derivation of downlink dimensioning for a wireless network employing the "high speed downlink packet access" (HSDPA) standard, currently being developed by the 3/sup rd/ Generation Partnership Project (3GPP) as part of the next stage in the evolution of the WCDMA standard (see Frenger, P. et al., "Performance Comparison of HARQ with Chase Combining and Incremental Redundancy for HSDPA", http://www.3gpp.org; Moulsley, T. J., 3G Mobile Commun. Technologies, IEE Conf. Publication No. 477, 2001). We determine the maximum possible cell radius such that the probability of outage, P/sub out/, at the cell's "worst" location does not exceed a preset value under full load conditions. The results are presented in the form of curves obtained by numerical integration of integral expressions. The results can be used, for instance, to find the increase in cell radius achievable by a certain reduction in the value of the signal-to-interference-plus-noise ratio (SINR) threshold used to define outage.
