WebFeb 15, 2024 · Source: Lin et al. 2024, fig. 1. In 4G/LTE, UE s support the maximum possible bandwidth of 20MHz. In 5G, transmission can go up to 400MHz per carrier. It's impractical to expect every UE to support such a high bandwidth. Therefore by design, it's possible for a 5G UE to communicate on a bandwidth smaller than the cell's channel bandwidth.
