Integrated dynamic channel assignment and power control in TDMAmobile wireless communication systems

摘要

With the evolution of analog mobile wireless communicationsnsystems into digital second- and third-generation systems, there isngrowing interest in finding more efficient ways of managing thenavailable resources, in particular radio spectrum and power. In thencontext of time division multiple access (TDMA) systems, this interestnhas led to the development of a variety of dynamic channel assignmentn(DCA) and power control (PC) algorithms. Despite the intense activity innboth the DCA and the PC arenas and some proposals for combined DCA withnPC, not enough work has been devoted to effectively integrating them. Innthis paper, the integration of DCA and PC is investigated and a familynof integrated algorithms is presented. These algorithms, fullyndistributed and cost adaptive, achieve capacity levels significantlynhigher than those of a system with only DCA or PC. With respect to ansystem without any DCA or PC, several-fold capacity increases arenobtained. Furthermore, these capacity levels are attained with usernmobility included in the analysis
