Abstract: 
This paper considers a multi-cell millimeter-wave (mmWave) massive multiple-input multiple-output (MIMO) system with mixed ADCs and hybrid beamforming architecture, in which antenna selection is applied to achieve intelligent assignment of high-resolution and low-resolution ADCs. Both exact and approximate closed-form expressions for the uplink achievable rate are derived in the case of maximum- ratio combining reception. The impacts on the achievable rate of user transmit power, number of radio frequency chains at base station, ratio of high-resolution ADCs, number of propagation paths, and quantization bits are analyzed. It is shown that the user transmit power can be scaled down inversely proportional to the number of antennas at a base station. We propose an efficient power allocation scheme by solving a complementary geometric programming problem. In addition, the energy efficiency is investigated and an optimal tradeoff between the achievable rate and power consumption is discussed. Our results will provide a useful reference for the study of mixed-ADC multi-cell mmWave massive MIMO systems with antenna selection.
