SINR and average per‐user data rate with different quantization mechanisms for channel norm. (a) The CDF of global channel norm and SINR for two feedback mechanisms under 10‐dB cell‐edge SNR, where the result of ‘Perfect Norm’, ‘Global 6 bit’, and ‘Per‐cell 18 bit’ overlap with each other. (b) The average data rates achieved using the perfect and quantized global channel norms, under both 0‐ and 10‐dB cell‐edge SNR.
