Differential Cell Measurement Reporting to Reduce Wireless Overhead
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently reporting cell measurements due to high overhead, which can impact throughput and increase latency, especially as network complexity and densification lead to an increased number of reported cell measurements.
Innovation Solution
Implementing differential cell measurement reporting, where a first cell measurement is reported, and one or more differential cell measurement values are reported relative to the first cell measurement value, reducing overhead by indicating quantities of cell measurements associated with different differential values using bitmaps, tables, and compression/truncation techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional cell measurement reporting is used, then complete cell measurement information is provided, but reporting overhead increases and latency increases
Solution Approach 1:
The patent changes the parameter representation from absolute cell measurement values to differential values relative to a reference cell measurement. This parameter transformation reduces the number of bits required to represent each measurement, thereby reducing reporting overhead while preserving the essential measurement information through differential encoding.
Solution Approach 2:
The patent extracts and reports only the differential portion of cell measurement values rather than transmitting complete absolute values for all measurements. By separating the reference measurement from the differential adjustments, the system reduces the total information volume that needs to be transmitted while maintaining measurement accuracy.
2Loss of information
If traditional cell measurement reporting is used, then complete cell measurement information is provided, but throughput decreases due to increased overhead
Solution Approach 1:
By transforming cell measurement parameters from absolute to differential representation, the patent reduces the bit width required for each measurement report. This parameter change decreases the total payload size, thereby increasing the proportion of useful data transmission and improving overall system throughput.
3Loss of information
If traditional cell measurement reporting is used, then all cell measurements are reported, but latency increases due to larger report size
Solution Approach 1:
The patent applies parameter transformation by encoding cell measurements as differential values relative to a reference, which reduces the number of bits required per measurement. This compact representation decreases the total report size, enabling faster transmission and reducing reporting latency while maintaining complete measurement information.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may report a first quantity of cell measurements associated with a first differential value and a second quantity of cell measurements associated with a second differential value. Notably, reporting the quantity of cell measurements associated with a given differential value differs from reporting a single differential cell measurement value by reference to the index identifying the given differential value. For example, the quantity of cell measurements may indicate how many cell measurements are associated with the given differential value, whereas reporting the single differential cell measurement value by reference to the index may indicate that a single cell measurement value is associated with the given differential cell measurement value.
