Adaptive RSRP Encoding Scheme for Wireless Beam Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, certain RSRP values may not be transmitted due to limitations in existing encoding schemes, which affect the accuracy and efficiency of beam management and data transmission.
Innovation Solution
A method and apparatus for determining and using multiple encoding schemes for RSRP transmission based on the difference between reference signal received power values, where a first encoding scheme is used for differences less than or equal to a threshold and a second encoding scheme with higher resolution is used for greater differences, involving the use of data structures with beam indicators and differential values.

Engineering Contradiction Analysis
1Measurement precision
If a single encoding scheme is used for RSRP transmission, then the device complexity is reduced, but certain RSRP values cannot be transmitted accurately
Solution Approach 1:
The patent applies dynamics by making the encoding scheme selectable and adaptable based on the RSRP difference value. The system dynamically chooses between first and second encoding schemes depending on whether the RSRP difference exceeds a threshold, allowing the encoding mechanism to adjust its behavior to match the specific transmission requirements rather than using a fixed approach.
Solution Approach 2:
The patent changes the encoding parameter (encoding scheme selection) based on the RSRP difference value. When the difference between RSRP values exceeds a threshold, the system switches to a different encoding scheme that can accommodate larger variations, thereby expanding the representable RSRP value range without increasing fundamental system complexity.
2Productivity
If a first encoding scheme is used for small RSRP differences, then transmission efficiency is improved, but RSRP values with large differences cannot be reported accurately
Solution Approach 1:
The system dynamically selects the appropriate encoding scheme based on the RSRP difference magnitude. For small differences within the threshold, the first encoding scheme maintains efficiency. When differences exceed the threshold, the system transitions to the second encoding scheme, ensuring that beam management operations maintain both efficiency and accuracy across varying signal conditions.
Solution Approach 2:
The encoding parameter is changed based on the RSRP difference value. The system monitors the difference between RSRP values and adjusts the encoding scheme accordingly, switching from a compact first scheme to a more capable second scheme when the difference exceeds the threshold, thereby preserving measurement precision across the full range of possible RSRP variations.
3Measurement precision
If RSRP values are encoded with high resolution, then measurement precision is improved, but the quantity of data transmitted increases
Solution Approach 1:
The patent segments the RSRP reporting into two cases based on the difference threshold. For small differences (first case), a compact encoding is used that transmits fewer bits. For large differences (second case), a different encoding structure is employed. This segmentation allows the system to optimize data volume for each scenario while maintaining the necessary precision for accurate beam management.
Solution Approach 2:
The data representation parameter is changed based on the RSRP difference magnitude. When differences are small, the system uses an encoding that requires fewer bits, reducing data transmission volume. When differences are large, the system switches to an encoding scheme that can represent the larger range with appropriate precision, balancing data volume and measurement accuracy dynamically.

AI summary
Apparatuses, methods, and systems are disclosed for determining an encoding scheme for RSRP transmission. One method includes determining multiple reference signal received power (“RSRP”) values. Each RSRP value of the multiple RSRP values corresponds to a beam measurement. The method includes determining a difference between a first RSRP value of the multiple RSRP values and a second RSRP value of the multiple RSRP values. The method also includes, in response to the difference being less than or equal to a predetermined threshold, transmitting information indicating the second RSRP value using a first encoding scheme. The method includes, in response to the difference being greater than the predetermined threshold, transmitting the information indicating the second RSRP value using a second encoding scheme. The first encoding scheme is different from the second encoding scheme.
