Measurement Report Offset Mapping for Neighbor Cell Sorting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In SAE/LTE networks, terminals face challenges in effectively reporting measurement values from adjacent cells using multiple access technologies, as the limited reporting space and differing value ranges across technologies make it difficult to determine which cells to report, especially when the number of cells meeting the criterion exceeds the allowed reporting capacity.
Innovation Solution
A method and device that map a 3-bit measurement report offset to a 6-bit value, using a 6-bit reported value mapping manner, to calculate a sorting value for sorting measured values during measurement reports, allowing for effective reporting of adjacent cells across various access technologies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the terminal reports measurement values of adjacent cells using multiple access technologies, then the reporting capacity is increased, but the reporting space is limited and cannot accommodate all cells meeting the criterion
Solution Approach 1:
The patent applies parameter changes by converting the 3-bit reported value offset to a 6-bit reported value through mapping. This parameter transformation enables consistent sorting across different access technologies (UTRAN and E-UTRAN) by unifying the value range representation, allowing the terminal to properly rank and select cells when the number of qualifying cells exceeds the reporting space limit.
2Measurement precision
If the terminal uses 3-bit reported value for E-UTRAN cells and 6-bit reported value for other RAT cells, then the reporting precision is maintained, but the sorting becomes inconsistent and the terminal cannot determine which cells to report
Solution Approach 1:
The patent transforms the 3-bit reported value offset into a 6-bit reported value through a defined mapping relationship. This parameter change ensures that all access technologies use a unified 6-bit value representation for sorting purposes, making the sorting process consistent and enabling the terminal to correctly identify which cells to report when exceeding the space limit.
Solution Approach 2:
The patent introduces a mapping relationship as an intermediary between the 3-bit and 6-bit reported value systems. This mapping acts as a mediator that converts the 3-bit offset into a comparable 6-bit value, allowing consistent sorting across different access technologies without losing the precision information embedded in the original 3-bit representation.
3Reliability
If the terminal reports the best cell for each RAT mode, then the reporting effectiveness is improved, but the terminal still cannot determine which cells to report when the number of qualifying cells exceeds the allowed number
Solution Approach 1:
The patent applies parameter changes by converting the 3-bit reported value offset to a 6-bit reported value. This transformation provides a unified sorting mechanism across all access technologies, enabling the terminal to consistently determine which cells to report when the number of qualifying cells exceeds the allowed reporting space, thereby improving reporting effectiveness while managing selection complexity.

AI summary
Embodiments of the present invention provide a method and a device for reporting a measurement report of an adjacent cell. The method includes: receiving a measurement report offset in a form of a 3-bit reported value delivered by a network; and mapping the measurement report offset to a mapping value in a form of a 6-bit reported value by using a 6-bit reported value mapping manner, and using the mapping value as a measurement report threshold used when sorting measured values. According to the embodiment of the present invention, the measurement report offset in a form of a 3-bit reported value is mapped to a mapping value in a form of a 6-bit reported value, and the mapping value is used as a measurement report threshold when sorting measured values during reporting of a measurement report. In this way, a sorting value required during reporting of the measurement report can be obtained, thereby effectively reporting a measurement report of an adjacent cell.
