Abstract [en]

We study the transmission power control in a cellular network where users mobility results  in a time varying gain matrix. A framework for evaluating the channel quality is specified,  and an asymptotic representation of the link gain evolution in time is obtained. Then, a  variant of a standard Distributed Constrained Power Control (DCPC) which copes with  user mobility is derived. These two power controls, as well as constant­received power and  constant­transmitted power controls are compared with respect to their outage probabilities  in a Manhattan­like microcellular system. The comparison reveals that the classical DCPC  algorithm has an outage probability close to one, unless some counter­measures are taken.  The time variant algorithm however, copes well with users mobility and provides a close to  an optimal scale up factor for the Signal to Interference Ratio (SIR) target. Furthermore, the  time variant algorithm provides a substantial improvement in spectrum utilization compared  to the other algorithms above.
