AI Technical Summary
Current wireless communications networks face challenges in efficiently supporting a diverse range of devices with varying data traffic profiles and requirements, such as high data rate applications, low latency, and high reliability, leading to inefficient power consumption and battery life issues in communications devices.
Implementing a low-power receiver and a main receiver in communications devices, with the method involving monitoring for a wake-up signal (WUS) within a predefined time window to trigger the main receiver to monitor for downlink channels during discontinuous reception (DRX) occasions, optimizing power usage based on actual network activity.
This approach enhances power saving in communications devices by reducing unnecessary receiver activation, thereby extending battery life and improving energy efficiency, especially for devices with low latency and reliability demands.
