How carrier aggregation combines multiple component carriers to boost 5G throughput, with intra-band and inter-band CA explained.

What this article will cover

  • What carrier aggregation (CA) is and the problem it solves
  • Primary cell (PCell) and secondary cell (SCell) concepts
  • Intra-band contiguous, intra-band non-contiguous, and inter-band CA
  • How CA increases peak throughput
  • CA in 5G NR vs LTE-A
