UTRA-TDD performance in a pico-cell deployment

This paper illustrates the performance of the high chip rate UTRA-TDD system deployed in an indoor office type environment. User terminals (or UEs) are distributed randomly within an office building that is served by 10 TDD base stations (BSs). Most terminals will generate 12.2kbit/s traffic but a small proportion of these generate 64kbit/s and 144kbit/s traffic. The results obtained by Monte Carlo simulation methods show (a) range of the served terminals, (b) path loss distributions for the served terminals, (c) inter-cell and intra-cell interference distributions, (d) capacity supported per base station and (e) coverage plots demonstrating the probability of outage at each office location. The TDD UL supports more capacity than the DL per radio resource.
