1. A system for improving pairing of user equipment to a primary component carrier in a Massive multiple-input multiple-output (MIMO) network, the system comprising:
one or more base stations having a plurality of nodes communicating with a first user equipment and a second user equipment via a plurality of component carriers, wherein the plurality of nodes comprises at least a first node communicating via a first component carrier, a second node communicating via a second component carrier, and a third node communicating via a third component carrier; and
a computing device in communication with the one or more base stations, wherein the computing device:
determines that the first user equipment and the second user equipment are paired to the first node of the plurality of nodes, the first node communicating via the first component carrier as a primary component carrier for the first user equipment and the second user equipment;
performs a first calibration check on the first node communicating via the first component carrier, wherein the first calibration check determines whether there is a break in uplink or downlink reciprocity;
in response to the first node communicating via the first component carrier failing the first calibration check, pairs the first user equipment with the second node communicating via the second component carrier as a primary component carrier to the first user equipment; and
in response to each of (i) the first node communicating via the first component carrier failing the first calibration check and (ii) an uplink capacity of the third node communicating via the third component carrier being greater than an uplink capacity of the second node communicating via the second component carrier, pairs the second user equipment with the third node communicating via the third component carrier as a primary component carrier to the second user equipment.
