Abstract

        This paper deals with the intertwined problems of feasibility,
power allocation and call admission control on the basis of the
signal-to-interference-ratio in multi-cell CDMA networks.
Positively homogeneous in-cell interference functions are introduced.
Under this general concept optimum power allocations
are determined by first solving in-cell interference
problems with fixed background noise, and subsequently a
small system of linear coupling equations.
This approach simultaneously clarifies the existence of some power
allocation such that minimum SIR requirements are fulfilled.
The decomposition is also utilized for designing
a decentralized admission control algorithm. Finally, guidelines
are given on how required parameters may be estimated in existing
network structures.
