Multi-user multiple-input multiple-output theory predicts many fold capacity gains by leveraging many antennas on wireless base stations to serve multiple clients simultaneously through multi-User BeamForming (MUBF). However, realizing a base station with a large number antennas is nontrivial, and has yet to be achieved in the real-world. The authors present the design, realization, and evaluation of Argos, the first reported base station architecture that is capable of serving many terminals simultaneously through MUBF with a large number of antennas. Designed for extreme flexibility and scalability, Argos exploits hierarchical and modular design principles, properly partitions baseband processing, and holistically considers realtime requirements of MUBF.
