Abstract
Dynamic channel assignment adapting both to traffic variations and to changing mobile locations is investigated for 1-D cellular radio systems. In order to adapt the channel assignment to the mobile locations, the cells are divided into subcells. The special properties of 1-D systems together with a simple propagation model are used to find the subcell configuration that minimizes the reuse distance. To transform this shorter reuse distance to increased capacity it is essential that the channel assignment algorithm can adapt to traffic variations between the subcells. This is obtained by using a slightly modified version of a previously proposed maximum-packing algorithm. Numerical results indicate that a channel assignment algorithm adaptive both to call traffic variations and to changing mobile locations may double the capacity compared to fixed channel assignment.Keywords
