TLDR
A new algorithm is proposed which gives an improvement in DFC algorithm such that it optimizes the transmission sum rate and reduces the number of outage users at the same time, and guarantees minimum acceptable SINR for all users in a feasible state.Abstract:
The well-known distributed power control algorithm with temporary removal and feasibility check (DFC) improves outage probability but it is not able to improve and maximize the system throughput simultaneously. In this paper, we have proposed a new algorithm which gives an improvement in DFC algorithm such that it optimizes the transmission sum rate and reduces the number of outage users at the same time. Also, the proposed algorithm guarantees minimum acceptable SINR for all users in a feasible state. Simulation results show that the proposed algorithm significantly improves system throughput, as compared with DFC and TPC with the same outage probability.read more

A simple distributed autonomous power control algorithm and its convergence
Gerard J. Foschini,Z. Miljanic +1 more
TL;DR: 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.

Pareto and Energy-Efficient Distributed Power Control With Feasibility Check in Wireless Networks
TL;DR: DFC significantly outperforms the existing schemes in addressing the gradual removal problem in terms of convergence, outage probability, and power consumption and shows that when target-SIRs are the same for all users, DFC minimizes the outage probability.

TL;DR: This work presents a distributed power control scheme with gradual soft removal, by which either TPC or OPC (opportunistic power control) is used, depending on whether the ratio of interference-to-path-gain is below or above a threshold that is chosen by each user in a distributed manner.
