From: Fairness, power allocation, and CSI quantization in block fading multiuser systems
The throughput versus the transmission power T under long-term fairness constraint, γ 1 = γ 2  = 0.3. Short-term power constraint, N = 2 users with fading coefficients μ1 = 1,μ2 = 2. With a long-term fairness constraint, no transmission is allowed at low SNRs, as the users’ individual throughput constraints (23.II) are not satisfied. Increasing the power, there is a threshold above which data transmission is possible since the users’ individual throughput constraints are satisfied.
