1. A system for multi-user (MU) multiple-input multiple-output (MIMO) pairing, the system comprising:
one or more antenna arrays comprising one or more antenna elements; and
one or more processors associated with the one or more antenna arrays, the one or more processors configured to execute operations comprising:
identifying a user device candidate for a user device pairing;
determining whether a combined spectral efficiency for the user device candidate is greater than an individual spectral efficiency associated with a first beam provided by the one or more antenna arrays and greater than another individual spectral efficiency for a second beam provided by the one or more antenna arrays; and
based on determining that the combined spectral efficiency is greater than the individual spectral efficiencies, pairing the user device candidate with another user device for sharing a resource via the combined spectral efficiency.
