Adaptive primary component carrier switching in massive MIMO based on beamforming calibration status

Methods, systems, and media for improving pairing of user equipment (UE) in a Massive multiple-input multiple-output (MIMO) system using carrier aggregation are provided. Component carriers (CC) used for communication with UEs in the network may undergo routine beamforming calibration checks to determine if the CCs are calibrated. If a CC fails calibration, then UEs that communicate with the CC as their primary component carrier (PCC) may not be receiving the high data throughput typically experienced through the PCC. In response to determining that a CC fails calibration, a computing device may pair UEs with another CC as their PCC until the original CC passes a calibration check. The computing device may determine which CC to pair to the UEs based on uplink capacity, bandwidth, or a passed calibration check.
