Abstract

This paper examines the use of intelligently deployed fixed relays to improve the performance of a UTRA-TDD 3G system. In this study, the benefits of intelligent relaying in the form of enhanced capacity and/or coverage and reduced RF emissions relative to a traditional cellular network are quantified. Simulations are carried out in a microcellular environment using propagation data from a site-specific model and an optimisation algorithm to determine the locations of base stations (BSs) and relay nodes in the system. A system level simulation of a UTRA-TDD W-CDMA system is used to quantify the benefits of the relayed over the non-relayed system. Results show significant improvements in capacity, spectrum efficiency and reductions in mean terminal transmit power in the relayed system over conventional cellular BS-only operation. The effects of different code allocation strategies for the relay nodes is also investigated, revealing that benefits in relaying will only be realised if relay nodes are allocated their own pool of spreading codes
