Low-Power Wake Up Radio Operation in Wireless Communication - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240196328 titled 'Low-Power Wake Up Radio Operation in Wireless Communication

Simplified Explanation: The patent application describes a system where a user equipment (UE) can switch between different radio states with a base station, enabling power-saving modes while still maintaining communication.

• The UE receives parameters from the base station for setting up a Wakeup Radio (WUR) state, which allows the UE to use a low-power radio for certain operations.
• The UE then enters the WUR state, where it can monitor signals, measure reference signals, and implement a discontinuous reception cycle for efficient signal monitoring.

Key Features and Innovation:

• Configuration of a Wakeup Radio (WUR) state for power-saving operations.
• Transition between main radio (MR) and WUR states based on parameters received from the base station.
• Monitoring, measuring, and implementing signal reception strategies in the WUR state.

Potential Applications: The technology can be applied in various wireless communication systems where power efficiency is crucial, such as IoT devices, mobile phones, and smart sensors.

Problems Solved: The technology addresses the need for power-saving modes in wireless communication devices without compromising on signal monitoring and reception capabilities.

Benefits:

• Extended battery life for devices.
• Efficient use of radio resources.
• Seamless transition between different radio states.

Commercial Applications: The technology can be utilized in IoT devices, mobile phones, smart home systems, and industrial automation for improved power efficiency and communication reliability.

Prior Art: Prior research in the field of power-saving modes in wireless communication devices and techniques for optimizing radio resource control states can provide valuable insights into the development of this technology.

Frequently Updated Research: Ongoing research in low-power communication protocols, energy-efficient wireless networks, and optimization algorithms for radio resource management can contribute to the advancement of this technology.

Questions about the Technology: 1. How does the configuration of Wakeup Radio (WUR) state contribute to power efficiency in wireless communication devices? 2. What are the potential challenges in implementing and optimizing the transition between main radio (MR) and WUR states in user equipment (UE)?

Original Abstract Submitted

a user equipment (ue) is configured to enter a radio resource control (rrc) state with a base station wherein network operations are performed using a main radio (mr), receive a first set of parameters from the base station for wakeup radio (wur) state operation wherein the ue enables a wur and powers down the mr to an off or deep sleep state, the first set of parameters including a parameter enabling the wur state operation and a configuration of wur reference signaling (wur-rs), receive a second set of parameters from the base station for wur setup and a wur signal (wur-s) configuration and enter the wur state from the rrc state, wherein, while in the wur state, the ue performs uses the wur including at least one of monitoring for the wur-s, measuring the wur-rs, or implementing a wur discontinuous reception (drx) cycle for wur-s and wur-rs signal monitoring.
