NR Zone-Based Signaling for Low-Latency Multicast Throughput
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communications systems face challenges in providing robust signaling for high throughput and low latency applications, particularly in supporting extended reality (XR) applications that require high data rates with tight delay budgets, while maximizing cell efficiencies and efficiently managing resources for UEs in common geographic areas.
Innovation Solution
The implementation of zone-based signaling in New Radio (NR) systems, where a base station partitions a geographic area into zones and maps channel transmission parts to these zones, allowing UEs to identify and select the appropriate channel transmission parts for communication, enabling efficient multicast or broadcast signals to multiple UEs in a common zone.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wireless signaling is used, then system simplicity is maintained, but communication reliability and throughput for high data rate applications deteriorate
Solution Approach 1:
The patent segments the geographic service area into multiple zones and divides channel transmission parts into separate groups, each associated with specific zones. This segmentation allows UEs to selectively receive only the channel transmission parts relevant to their location, improving communication reliability for high data rate applications while managing signaling complexity through structured organization.
Solution Approach 2:
The patent applies local quality by providing different channel transmission parts to different zones based on local UE requirements. Each zone receives customized channel transmission parts optimized for its specific geographic area and UE density, enhancing communication reliability locally while the overall system maintains manageable complexity through this distributed approach.
2Productivity
If more channel transmission parts are provided to support high throughput, then data rate increases, but resource usage efficiency deteriorates
Solution Approach 1:
The patent enables UEs to discard channel transmission parts that are not relevant to their zone, avoiding unnecessary processing and resource consumption. By recovering and processing only the essential channel transmission parts associated with their specific zones, UEs achieve high data rates while improving overall resource usage efficiency and reducing energy waste.
Solution Approach 2:
The patent implements partial action by providing more channel transmission parts than traditionally needed (excessive action) to ensure high throughput requirements are met, while UEs selectively process only the necessary portions (partial action) based on their zone associations. This approach achieves high data rates without proportionally increasing resource consumption across the entire system.
3Adaptability or versatility
If zone-based partitioning is implemented, then resource management efficiency improves, but system complexity increases
Solution Approach 1:
The patent applies universality by creating a multi-functional zone-based framework that simultaneously achieves multiple objectives: geographic area management, UE association tracking, channel transmission part distribution, and resource allocation optimization. This universal approach improves resource management efficiency across diverse scenarios while the standardized multi-functional structure helps manage system complexity through consolidation.
4Loss of time
If selective channel transmission part reception is enabled, then latency is reduced, but processing complexity at UE increases
Solution Approach 1:
The patent implements preliminary action by pre-associating channel transmission parts with specific zones before transmission. UEs can immediately identify and select the relevant channel transmission parts for their zone without requiring complex real-time analysis, thereby reducing latency while the pre-established associations simplify the UE processing requirements.
Data Source
AI summary
Methods, systems, and devices for wireless communications are described. According to one or more aspects, a device, such as a user equipment (UE), may receive a signal including one or more channel transmission parts associated with one or more zones. The UE may identify, based on receiving the signal, at least one zone of the one or more zones that is associated with the UE. Additionally or alternatively, the UE may identify multiple zones of the one or more zones that are associated with the UE. The UE may select a channel transmission part of the one or more channel transmission parts based on receiving the signal and the identified zone associated with the UE. The UE may decode the one or more selected channel transmission parts, and may communicate based on the decoded channel transmission part or the decoded channel transmission parts.
