UE Activity Alignment for XR Traffic Power Savings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional UE data transmission systems experience power drain due to periodic activity and inactivity periods, particularly with XR traffic that requires synchronized data flows across multiple periods, leading to high battery consumption and inefficient resource utilization.
Innovation Solution
User equipment (UE) assists in aligning data transmission activity by determining resource adjustments and generating alignment parameters to synchronize data transmission, reducing the number of active periods through network resource aggregation and delay strategies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data transmission is performed periodically across multiple periods to support XR traffic flows, then synchronization between traffic flows is improved, but power consumption increases due to frequent active periods
Solution Approach 1:
The patent combines multiple periodic transmission periods into a single aggregated transmission period. Multiple transport blocks that would traditionally be transmitted across separate periodic intervals are merged into one consolidated transmission, reducing the number of active periods while maintaining synchronization. This is achieved through the UE reporting activity alignment parameters that indicate readiness to aggregate transmissions.
Solution Approach 2:
The UE performs preliminary actions by monitoring multiple traffic flows and determining when they are synchronized and ready for aggregated transmission. The UE proactively reports activity alignment parameters to the network before aggregation occurs, allowing the network to prepare for consolidated resource allocation. This preliminary synchronization check ensures that when aggregation happens, all necessary data is ready, maintaining reliability while reducing power consumption.
2Use of energy by moving object
If network resources are aggregated within fewer active periods, then power consumption is reduced, but resource allocation complexity increases
Solution Approach 1:
The UE acts as an intermediary that simplifies the aggregation process for the network. Instead of the network directly managing complex synchronization and aggregation of multiple traffic flows, the UE monitors the flows, determines alignment opportunities, and reports activity alignment parameters to the network. This intermediary role offloads complexity from the network while enabling efficient resource aggregation that reduces power consumption.
Solution Approach 2:
The system implements feedback mechanisms where the UE continuously monitors traffic flow synchronization status and reports activity alignment parameters back to the network. This feedback loop allows the network to dynamically adjust resource aggregation based on actual synchronization conditions, simplifying resource allocation decisions while maintaining power efficiency. The feedback ensures that aggregation only occurs when appropriate, balancing complexity and energy savings.
3Productivity
If multiple transport blocks are used for data transmission, then data throughput is improved, but battery consumption increases due to spread-out transmission scheduling
Solution Approach 1:
The patent merges multiple transport blocks that would traditionally be transmitted across separate periodic intervals into a single aggregated transmission event. This consolidation maintains the total data throughput by transmitting all necessary transport blocks together, while significantly reducing battery consumption by eliminating the need for the UE to activate its transmitter multiple times across different periods. The activity alignment parameters enable this merging by indicating when multiple flows are ready for simultaneous transmission.

Methods, systems, and apparatuses for synchronizing data transmission activity by user equipment (UE). In one aspect, the method comprises determining, by the UE and based on current usage of resources, that alignment of subsequent usage of resources is to be adjusted, generating, by the UE, data that indicates a plurality of activity alignment parameters that are to be adjusted in order to cause the adjusted alignment of subsequent usage of resources, encoding, by the UE, the generated data for transmission to a base station, and transmitting, by the UE, the encoded data to the base station.
