Meningkatkan lebar jalur secara berterusan untuk meningkatkan kapasiti adalah tidak praktikal kerana kekurangan ketersediaan spektrum. Mujurlah, berdasarkan ciri-ciri rangkaian selular multihop (MCN), skim penggunaan semula frekuensi padat baharu telah dicadangkan untuk menyediakan kecekapan penggunaan spektrum yang lebih tinggi dan kapasiti yang lebih besar tanpa meningkatkan kos pada rangkaian. Stesen pangkalan (BS) dan stesen geganti (RS) boleh menghantar serentak pada frekuensi yang sama mengikut skema penggunaan semula frekuensi padat. Walau bagaimanapun, dalam situasi ini, stesen mudah alih (MS) berhampiran sempadan liputan akan mengalami gangguan yang serius dan kualiti trafiknya tidak dapat dijamin. Untuk mengurangkan gangguan sambil mengekalkan kecekapan penggunaan spektrum tinggi, makalah ini memperkenalkan skim penggunaan semula frekuensi pecahan (FFR) ke dalam rangkaian selular multihop, di mana prinsip skema FFR dan ciri konfigurasi sumber frekuensi diterangkan, kemudian penghantaran (Tx ) penggunaan kuasa BS dan RS dianalisis. Skim yang dicadangkan boleh memenuhi keperluan beban trafik yang tinggi dalam sistem selular masa hadapan dan memaksimumkan faedah dengan mengurangkan penggunaan kuasa Tx. Keputusan berangka menunjukkan bahawa FFR yang dicadangkan dalam penggunaan semula frekuensi padat mencapai kebarangkalian liputan sel yang lebih tinggi dan kapasiti yang lebih besar berkenaan dengan skim konvensional.

Abstract: Continuously increasing the bandwidth to enhance the capacity is impractical because of the scarcity of spectrum availability. Fortunately, on the basis of the characteristics of the multihop cellular networks (MCNs), a new compact frequency reuse scheme has been proposed to provide higher spectrum utilization efficiency and larger capacity without increasing the cost on network. Base stations (BSs) and relay stations (RSs) could transmit simultaneously on the same frequency according to the compact frequency reuse scheme. In this situation, however, mobile stations (MSs) near the coverage boundary will suffer serious interference and their traffic quality can hardly be guaranteed. In order to mitigate the interference while maintaining high spectrum utilization efficiency, this paper introduces a fractional frequency reuse (FFR) scheme into multihop cellular networks, in which the principle of FFR scheme and characteristics of frequency resources configurations are described, then the transmission (Tx) power consumption of BS and RSs is analyzed. The proposed scheme can both meet the requirement of high traffic load in future cellular system and maximize the benefit by reducing the Tx power consumption. Numerical results demonstrate that the proposed FFR in compact frequency reuse achieves higher cell coverage probability and larger capacity with respect to the conventional schemes.
