TLDR
For wireless cellular communication systems, one seeks a simple effective means of power control of signals associated with randomly dispersed users that are reusing a single channel in different cells, and the authors demonstrate exponentially fast convergence to these settings whenever power settings exist for which all users meet the rho requirement.Abstract:
For wireless cellular communication systems, one seeks a simple effective means of power control of signals associated with randomly dispersed users that are reusing a single channel in different cells. By effecting the lowest interference environment, in meeting a required minimum signal-to-interference ratio of rho per user, channel reuse is maximized. Distributed procedures for doing this are of special interest, since the centrally administered alternative requires added infrastructure, latency, and network vulnerability. Successful distributed powering entails guiding the evolution of the transmitted power level of each of the signals, using only focal measurements, so that eventually all users meet the rho requirement. The local per channel power measurements include that of the intended signal as well as the undesired interference from other users (plus receiver noise). For a certain simple distributed type of algorithm, whenever power settings exist for which all users meet the rho requirement, the authors demonstrate exponentially fast convergence to these settings. >read more

Optimality of Treating Interference as Noise: A Combinatorial Perspective
Xinping Yi,Giuseppe Caire +1 more
TL;DR: In this paper, the problem of determining the generalized degrees of freedom (GDoF) region achievable by treating interference as Gaussian noise (TIN) derived by Geng et al. from a combinatorial optimization perspective was reformulated for single-antenna Gaussian interference channels, and a low-complexity GDoF-based distributed link scheduling and power control mechanism was proposed.

Adaptive cell sectorization for CDMA systems
Cem U. Saraydar,Aylin Yener +1 more
TL;DR: It is observed that, with adaptive sectorization, where the sector boundaries are determined in response to users' locations, received and transmit power savings are achieved, and the number of users served by the system is increased compared to uniform sectorization of the cell.

Distributed Learning Policies for Power Allocation in Multiple Access Channels
TL;DR: This work analyzes the power allocation problem for orthogonal multiple access channels by means of a non-cooperative potential game in which each user distributes his power over the channels available to him and finds that users still converge to equilibrium.
