Wake Up Signal Pool for Wireless Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently waking up multiple user equipment (UEs) without causing interruptions in beam communications, which leads to increased power and processing consumption.
Innovation Solution
The implementation of a wake-up signal (WUS) pool that includes contiguous candidate time resources allows a base station to transmit a WUS to multiple UEs within a shared pool, eliminating the need for multiple interruptions and beam switches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a base station transmits individual wake-up signals to multiple user equipment separately, then each user equipment can be reliably woken up, but the base station experiences increased interruptions and beam switches leading to higher power and processing consumption
Solution Approach 1:
The patent combines multiple individual wake-up signals into a single pooled resource structure where multiple user equipments share a common wake-up signal opportunity. Instead of transmitting separate signals to each UE, the base station creates a WUS pool that multiple UEs can monitor together, reducing the number of transmissions and beam switches required while maintaining reliable wake-up delivery to all targeted UEs.
Solution Approach 2:
The wake-up signal pool serves multiple user equipments simultaneously with a single signal structure. The pooled WUS resource performs the universal function of waking up any UE within the pool, eliminating the need for dedicated individual signaling and reducing overall base station power consumption while maintaining reliability for each UE.
2Reliability
If a base station transmits individual wake-up signals to multiple user equipment separately, then each user equipment can be reliably woken up, but the system experiences increased signaling resource consumption
Solution Approach 1:
The patent merges multiple individual wake-up signal transmissions into a single pooled signaling structure. By combining the signaling resources into one WUS pool that serves multiple UEs, the system reduces the total quantity of signaling resources consumed while maintaining the reliability needed to wake up each individual UE within the pool.
3Reliability
If a base station transmits individual wake-up signals to multiple user equipment separately, then each user equipment can be reliably woken up, but the system experiences increased processing consumption
Solution Approach 1:
The patent combines multiple individual wake-up signal processing operations into a single pooled processing structure. The base station processes one WUS pool transmission instead of multiple individual signals, reducing processing complexity and computational overhead while maintaining the ability to reliably wake up multiple UEs through the shared pool resource.
4Reliability
If a base station transmits individual wake-up signals to multiple user equipment separately, then each user equipment can be reliably woken up, but the system experiences increased interruptions in beam communications
Solution Approach 1:
The patent merges multiple separate wake-up signal transmissions into a single pooled transmission opportunity. This consolidation reduces the number of interruptions required in beam communications, as the base station performs fewer beam switches and transmissions while still maintaining reliable wake-up delivery to all targeted user equipments within the pool.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may monitor a subset of time resources in a wake up signal (WUS) pool, wherein the WUS pool includes contiguous candidate time resources for receiving a WUS. The UE may detect the WUS based at least in part on monitoring the subset of time resources. Numerous other aspects are provided.
