Supports both FDD (frequency division duplex) and TDD (time division duplex).

In each 5MHz cell, it can accommodate at least 200 dynamic users.

The one-way transmission delay of the user plane is less than 5ms, and the transition time of the control plane from sleep state to active state is less than 50ms.
