The cumulative distribution function of weighted sum rate. This includes weighted sum rates with full-channel selection (labeled as full channel), dominant channel paths-based selection (labeled as dom-path-channel), dominant angles and amplitudes-based selection (labeled as dom-angle-amp), zero-measurement selection (labeled as zero-measurement) and uniformly random user selection (labeled as random), respectively, where a 64-antenna base-station selects \(K = 8\) users out of \(N = 100\) users for downlink beamforming based on measured channels
