Solution Overview
Problem
The inefficiency in setting parameters for simulating a base station in mobile terminal testing devices, particularly in determining Transport Block Size (TBS) and code rate, leads to a cumbersome testing process that reduces test efficiency.
Innovation Solution
A mobile terminal testing device with a control unit that automatically searches for and presents the Modulation and Coding Scheme (MCS) settings that satisfy predetermined conditions, including a code rate of equal to or less than a standard value and maximum Transport Block Size (TBS), using a table-based method to reduce user burden and enhance testing efficiency.

Engineering Contradiction Analysis
1Reliability
If parameters for simulating a base station are manually adjusted to achieve desired TBS and code rate, then communication performance can be optimized, but the testing process becomes cumbersome and test efficiency decreases
Solution Approach 1:
The control unit automatically searches for and determines MCS set values that satisfy predetermined conditions (code rate ≤ standard value and maximum TBS) without requiring manual parameter adjustment. The system performs self-optimization by automatically selecting appropriate MCS values based on the simulated base station parameters, thereby maintaining communication performance while significantly improving test efficiency.
Solution Approach 2:
The system automatically changes MCS parameters based on predetermined conditions and search criteria. The control unit searches through possible MCS values and selects those that satisfy the code rate constraint and maximize TBS, dynamically adjusting parameters without manual intervention while maintaining optimal communication performance.
2Reliability
If multiple parameters are adjusted to achieve desired TBS and code rate, then communication standards can be satisfied, but the complexity of parameter setting increases
Solution Approach 1:
The control unit extracts and focuses on the key constraint conditions (code rate ≤ standard value and maximum TBS) from the complex parameter space. By isolating these critical constraints, the system automatically searches for MCS values that satisfy the standards without requiring manual adjustment of multiple interdependent parameters, thereby reducing setting complexity while ensuring standard compliance.
Solution Approach 2:
The system implements a feedback mechanism where the control unit evaluates each potential MCS value against the predetermined conditions (code rate constraint and TBS maximization). This iterative evaluation process provides feedback that guides the automatic selection of compliant MCS values, simplifying the parameter setting process while ensuring standard compliance.
