Abstract:

We apply dynamic slot allocation with power-shaping to TDMA-based (pure or hybrid) mobile radio systems. We show that this technique, originally proposed by the Authors for fixed broadband wireless access systems, where interference is mitigated by the use of highly directional antennas, is able to increase the capacity even in full frequency reuse cellular systems with omnidirectional antennas. By using a set of power profiles, suitably defined here for hexagonal cells with three sectors, that limit (or shape) the power transmitted in each slot of the frame, this allocation technique partially organizes the intercell and intersector interference in the available slots and makes it partially predictable. This allows an efficient use of radio resources, when the base stations assign radio resources in an uncoordinated fashion without the need of centralized strategies requiring heavy signaling load.
