Abstract

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 Time Variant distributed constrained Power Control (TVPC) which copes with user mobility is derived. The algorithm is compared to a classical Distributed Constrained Power Control (DCPC), as well as to a constant-received power control and constant-transmitted power. The comparison reveals that the classical DCPC exhibits an outage probability close to one, unless some counter-measures are taken. The TVPC 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.
