Adaptive radio resource management in F/TDMA cellular networks using smart antennas
Christian Hartmann, Jörg Eberspächer · European Transactions on Telecommunications · 2001
Abstract In this paper we discuss different Radio Resource Management (RRM) strategies for smart antenna cellular networks. The focus is on adaptive strategies which combine spatial channel reuse within the cell with dynamic inter—cell channel allocation. In particular, three different SDMA channel allocation strategies are described and compared in terms of complexity as well as traffic capacity. The comparison is done by means of system simulations of a multi—cellular environment. We show that with a growing degree of freedom the RRM strategies yield better results in terms of traffic capacity while the number of handoffs per call increases and the complexity grows.
