Test Resource Block Allocation for Wireless Transmission Parameter Evaluation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for testing transmission parameter values in wireless communication systems, such as antenna tilts, during operational mode lack accuracy and do not effectively evaluate settings with minimal impact on service quality, as they rely on simulations that may not reflect real-world conditions or changes in the environment.
Innovation Solution
A method where a radio network node allocates a test resource block to perform test transmissions with varying transmission parameter values, allowing for real-time evaluation of these values during operational mode, using available time and frequency resources divided into resource blocks, and obtaining performance data to assess the impact on radio quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If simulations are used to evaluate transmission parameter values, then testing can be performed during operational mode, but the accuracy of the evaluation is reduced because simulations may not reflect real-world conditions
Solution Approach 1:
The patent creates a test resource block that is a copy of the normal resource block structure, allowing test transmissions to be performed in parallel with normal operations. This copying approach enables real-world testing while maintaining the operational mode, resolving the contradiction between testing capability and measurement accuracy.
Solution Approach 2:
The patent segments the available radio resources into normal resource blocks for regular communication and test resource blocks for evaluation purposes. By dividing the resource space, the system can perform accurate real-world measurements without interfering with normal operations, thus improving both testing reliability and measurement precision.
2Measurement precision
If transmission parameter values are tested in real environment, then measurement accuracy is improved, but service quality may be impacted
Solution Approach 1:
The patent divides the radio resources into separate test resource blocks and normal resource blocks. By segmenting the spectrum and time resources, the system can perform accurate real-world measurements in test blocks without affecting service quality in normal blocks, thus resolving the contradiction between measurement accuracy and service quality impact.
Solution Approach 2:
The patent applies local quality by creating dedicated test resource blocks with specific characteristics (different from normal blocks) that are localized in the time-frequency resource space. This allows the test transmissions to have different properties (for measurement purposes) without degrading the quality of normal service transmissions.
3Productivity
If test transmissions are performed using available resources, then system capacity is utilized, but transmission parameter testing is limited by resource constraints
Solution Approach 1:
The patent makes the test resource block universal by allowing it to carry both test transmissions for parameter evaluation and normal communications. This multi-functionality enables the system to maximize resource utilization while maintaining the ability to test various transmission parameter values, resolving the contradiction between productivity and adaptability.
