In cellular systems a large reuse distance reduces co-channel interference while a small reuse distance increases bandwidth allocated to each cell. The optimal reuse distance is chosen to balance these two factors. Instead of applying a fixed reuse distance to the entire system, in this paper we study the effect of adaptive channel reuse based on channel strength. Assuming the traditional single base station transmission, adaptive channel reuse under different propagation models, with or without fading, is analyzed for the Wyner linear cellular model. A new approach where base stations collaborate in transmission is also considered. We observe that adjacent base cooperation does not show much advantage over traditional single base transmission under intracell orthogonal schemes and AWGN channel models. In order to fully exploit the benefit of base station cooperation, more sophisticated transmission schemes need to be investigated.
