... 25 on the presented insights could be considered in the future. The proposed uplink interference characterization can also be used to analyze systems like massive MIMO, where it plays a crucial role [30]. Performance analysis for decoupled association incorporating the cost of possible architectural changes [20] could also be one area of future investigation. ACKNOWLEDGMENT The authors appreciate hel...

...INTRODUCTION Large-scale multiple-input multiple-output (MIMO) or ‘‘massive MIMO’’, a new technique that employs hundreds or even thousands of antennas at base station (BS) to simultaneously serve multiple users, has been widely investigated for its numerous merits, such as high spectrum and energy efficiency, high spatial resolution, and simple transceiver design [1]....
