Chapter 5: Power Control and Resource Allocation

Learning Objectives

• Formulate the max-min fairness power control problem and solve it via bisection and linear feasibility
• Derive the proportional fairness solution and its connection to the Nash bargaining problem
• Understand why weighted sum-rate maximization is NP-hard and apply successive convex approximation
• Implement heuristic power control schemes including fractional power control and max-min via fixed-point iteration
• Apply the Bjornson-Hoydis-Sanguinetti framework for power control under imperfect CSI
