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

Adaptive closed-loop power control with quantized feedback and loop filtering
TL;DR: A new power control scheme is proposed which has several novel features: it uses an adaptive optimal quantizer at the receiver for transmitting discrete feedback information and an adaptive quantization scaler/restorer followed by a loop filter at the transmitter.

Cooperative Precoding with Limited Feedback for MIMO Interference Channels
Kaibin Huang,Rui Zhang +1 more
TL;DR: In this article, the authors considered finite-rate CSI feedback from receivers to their interfering transmitters in the two-user multiple-input-multiple-output (MIMO) interference channel, called cooperative feedback, and proposed a systematic method for designing transceivers comprising linear precoders and equalizers.
