Abstract
In a synchronized, cellular radio telecommunications system that employs frequency hopping, system performance can be significantly improved by more fully exploiting interference diversity, while maintaining frequency diversity, which is already associated with frequency hopping techniques. In order to more fully exploit interference diversity, each cell belonging to a group of synchronized cells in the cellular radio telecommunications system is allocated a common, reference frequency hopping sequence. However, the various mobile stations operating in any one of these cells is allocated a different frequency offset hopping sequence.
