What is DRX?

DRX typically refers to Discontinuous Reception. It's a power-saving technique used in wireless communication technologies like 4G LTE and 5G NR. By allowing the mobile device's receiver to be active only during specific periods and sleep during others, DRX significantly reduces battery consumption. The network configures the device with parameters that dictate when to wake up and listen for control signals or data transmissions. It's most commonly used in mobile devices to extend battery life, especially when the device is in an idle or semi-active state.
