Rate cumulative distribution function for FUE 1 (blue) and FUE 2 (red) when 2-bit mode 1 is applied with different beamforming methods (no SP scheduling implemented). Interference scenario: ${\stackrel{¯}{\gamma }}_{1\to 1}=15$ dB (good signal), ${\stackrel{¯}{\gamma }}_{1\to 2}=0$ dB (weak interference), ${\stackrel{¯}{\gamma }}_{2\to 1}=15$ dB (strong interference), and ${\stackrel{¯}{\gamma }}_{2\to 2}=20$ dB (excellent signal). All cases: P _N used as reference power. Solid: No TBF. Dashed: 2-bit mode 1 (FAP 1 ego/FAP 2 ego). Dashed-dotted: 2-bit mode 1 (FAP 1 ego/FAP 2 alt). Dotted: ∞-bit mode 1 (FAP 1 ego/FAP 2 alt).
