Abstract This paper introduces a channel assignment problem in mixed cellular telephone networks consisting of both dynamic and fixed base stations. In mixed networks radio channels have to be allocated to the fixed stations in such a way that enough freedom is left for dynamic transmitters. We discuss some possibilities of evaluating fixed assignment plans and propose two optimization criteria, which form a generalization of list coloring and $T$-coloring problems. We give a complete analysis of the computational complexity of these criteria in the case when the dynamic part of the network can be modeled as a graph with bounded treewidth or as a graph whose every connected component is complete or almost complete.
