LOW POWER WAKE-UP SIGNAL WITH TWO PARTS IN TIME DOMAIN - A simplified explanation of the abstract

This abstract first appeared for US patent application 18465698 titled 'LOW POWER WAKE-UP SIGNAL WITH TWO PARTS IN TIME DOMAIN

Simplified Explanation

Abstract

Various embodiments provide techniques for a low power wake-up signal (LP-WUS) with two parts. The LP-WUS is received by a wake-up receiver of a user equipment (UE) and used to trigger a main receiver of the UE to wake up or enter a higher power state. The first part indicates the presence and/or other characteristics of the second part. The first and second parts are transmitted in one or more symbols, slots, or time resource units.

Explanation

  • The patent application describes a method for using a low power wake-up signal (LP-WUS) to wake up a main receiver in a user equipment (UE).
  • The LP-WUS consists of two parts, with the first part indicating the presence and characteristics of the second part.
  • The LP-WUS is received by a wake-up receiver in the UE, which then triggers the main receiver to wake up or enter a higher power state.
  • The first and second parts of the LP-WUS are transmitted in one or more symbols, slots, or time resource units.

Potential Applications

  • This technology can be applied in various wireless communication systems, such as cellular networks, IoT devices, and wireless sensor networks.
  • It can be used to efficiently wake up specific devices or receivers in a network, reducing overall power consumption.
  • LP-WUS can enable energy-efficient communication in battery-powered devices, extending their battery life.

Problems Solved

  • Traditional wake-up signals often require high power consumption, which is not suitable for battery-powered devices.
  • Existing wake-up techniques may lack the ability to indicate the presence and characteristics of the main signal, leading to inefficient power usage.
  • This technology solves these problems by providing a low power wake-up signal with two parts, allowing for efficient triggering of main receivers.

Benefits

  • The LP-WUS enables energy-efficient communication by minimizing power consumption during idle periods.
  • It allows for targeted wake-up of specific devices or receivers, reducing unnecessary power usage.
  • By indicating the presence and characteristics of the main signal, the LP-WUS optimizes power usage and improves overall system efficiency.


Original Abstract Submitted

Various embodiments herein provide techniques for a low power wake-up signal (LP-WUS) with two parts. The LP-WUS may be received by a wake-up receiver of a user equipment (UE) and used to trigger a main receiver of the UE to wake up (e.g., turn on or enter a higher power state). The first part may be used to indicate the presence and/or other characteristics of the second part. The first and second parts may each be transmitted in one or more symbols, slots, or time resource units. Other embodiments may be described and claimed.
