Channel information assisted reuse partitioning-a distributed dynamic channel assignment algorithm based on reuse partitioning

Abstract

A new practical algorithm is proposed for dynamic assignment (DCA) for microcellular systems. The algorithm, called channel information assisted reuse partitioning (CIRP), employs information on assigned number versus signal level measured at each base station. The information is utilized to assign a new channel, and is updated in each assignment process in a distributed manner. Simulation results show that CIRP successfully realizes the reuse partitioning and achieves rapid search and higher spectral efficiency as compared with a DCA algorithm without using the information. The spectral efficiency of about 2.8/spl sim/3.8 times as higher as that of the fixed assignment (FCA) or random assignment (RCA) strategies is achieved by CIRP. >
