Light L1 Measurement Report for Wireless UE
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies in reporting layer 1 (L1) measurement reports, leading to increased overhead and resource consumption, especially when channel conditions remain static.
Innovation Solution
The method involves a user equipment (UE) performing measurements of reference signals and transmitting a light L1 measurement report when certain conditions are met, such as measurements being within a specified tolerance of previous reports. This report omits or contains different information compared to a normal L1 measurement report, reducing payload and overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a normal L1 measurement report is transmitted every time measurements are performed, then measurement accuracy and network responsiveness are maintained, but overhead and resource consumption increase significantly
Solution Approach 1:
The patent applies dynamics by switching between two types of measurement reports (normal and light reports) based on channel condition changes. The system dynamically adjusts the reporting mode: using normal reports when channel conditions change significantly and light reports when conditions remain stable, thereby optimizing the balance between measurement accuracy and resource consumption.
Solution Approach 2:
The patent changes the parameter of report content by introducing a light L1 measurement report that includes only essential information (such as reference signal index and measurement value) compared to the full normal report. This parameter change allows the system to reduce overhead while maintaining sufficient accuracy for network optimization.
2Productivity
If full L1 measurement reports are transmitted continuously, then network optimization is maintained, but latency increases due to processing and transmission overhead
Solution Approach 1:
The patent extracts only the most critical information from full L1 measurement reports to create light reports. By taking out and transmitting only essential parameters (reference signal index, measurement value) rather than complete report structures, the system reduces transmission time and processing overhead while maintaining network optimization capability.
3Measurement precision
If measurement reports include all available information, then measurement precision is maximized, but device complexity and processing requirements increase
Solution Approach 1:
The patent segments measurement reports into two distinct types: normal reports containing full information for significant channel changes and light reports containing minimal information for stable conditions. This segmentation allows the system to process reports with appropriate complexity levels matched to actual network needs, reducing overall processing burden while maintaining precision when required.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may perform a measurement of one or more reference signals associated with a layer 1 (L1) measurement report. The UE may transmit a light L1 measurement report associated with the measurement of the one or more reference signals based at least in part on the measurement of the one or more reference signals satisfying one or more light L1 measurement report conditions, wherein the light L1 measurement report is based at least in part on a previously transmitted normal L1 measurement report, and wherein the light L1 measurement report at least one of: omits at least some information that was transmitted in the previously transmitted normal L1 measurement report, or contains different information than the previously transmitted normal L1 measurement report. Numerous other aspects are described.
