Radio Network Node Paging Signal Carrier Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The coexistence of Rel-15 WUS and Rel-16 UE-group WUS in wireless communication networks leads to unnecessary UE wake-ups, as current systems cannot separately configure paging for different types of UEs, resulting in increased power consumption and reduced battery life.
Innovation Solution
Configuring separate carriers for Rel-15 WUS and Rel-16 UE-group WUS, allowing for frequency multiplexing and enabling the network to page UEs with different releases simultaneously, thereby reducing false paging and improving power management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If separate carriers are configured for Rel-15 WUS and Rel-16 UE-group WUS, then false paging is reduced and power consumption is lowered, but device complexity and network configuration complexity increase
Solution Approach 1:
The patent segments the paging signal transmission by allocating different carriers for Rel-15 WUS and Rel-16 UE-group WUS. This segmentation allows the network to separately configure and manage paging for different UE types, enabling targeted paging that reduces false wake-ups and power consumption while maintaining backward compatibility.
Solution Approach 2:
The patent introduces frequency domain separation by using different carriers (frequency resources) for different WUS types. This dimensional separation in the frequency domain enables simultaneous support for both Rel-15 and Rel-16 paging mechanisms without interference, resolving the contradiction between reduced power consumption and increased configuration complexity.
2Adaptability or versatility
If separate carriers are configured for different UE types, then coexistence of Rel-15 and Rel-16 UEs is improved, but network resource allocation complexity increases
Solution Approach 1:
The patent segments network resources by assigning specific carriers to specific UE types (Rel-15 vs. Rel-16). This resource segmentation enables independent optimization and configuration for each UE type, improving coexistence capability while allowing the network to manage complexity through structured resource allocation.
Solution Approach 2:
The patent creates a universal paging framework where multiple WUS types can coexist on different carriers. This multi-functional approach allows the network to serve both legacy and advanced UE types simultaneously, enhancing adaptability while maintaining a unified paging architecture that manages resource allocation complexity.

AI summary
Embodiments relate to e.g. a method performed by radio network node (12) for paging a UE (10) in a wireless communication network. The UE (10) transmits a paging signal on a carrier to the UE (10), wherein the carrier is associated with a second paging signal for a second type of UEs. A first number of carriers are configured for a first paging signal of a first type of UEs and a second number of carriers are configured for the second paging signal of the second type of UEs, wherein the first paging signal comprises a first wake-up signal, WUS, and wherein the second paging signal comprises a group wake up signal, WUS, for a group of UEs of the second type of UEs.
