1. A system comprising:
one or more processors;
a memory; and
one or more components stored in the memory and executable by the one or more processors to perform operations comprising:
identifying a cell, from a plurality of cells that includes a first cell associated with a first bandwidth and a second cell associated with a second bandwidth, to use as a primary cell (PCell) for carrier aggregation (CA) in a fifth generation (5G) network;
using the cell as the PCell for a user equipment (UE);
generating predicted network conditions by predicting network conditions of the 5G network;
determining whether to switch the PCell to a different one of the plurality of cells based, at least in part, on the predicted network conditions of the 5G network; and
switching the PCell to the different one of the plurality of cells.
