A new practical algorithm is proposed for dynamic channel assignment (DCA) for microcellular systems. The algorithm, called “channel information assisted reuse partitioning (CIRP),” employs information on assigned channel 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 channel search and higher spectral efficiency as compared with a DCA algorithm without using the channel information. The spectral efficiency of about 2.8~3.8 times as higher as that of the fixed channel assignment (FCA) or random channel assignment (RCA) strategies is achieved by CIRP
