1Productivity

If multiple sets of cell selection and reselection parameters are configured and transmitted to terminals, then communication transmission efficiency and data transmission rate are improved, but device complexity and signaling overhead increase

Engineering Contradiction:

Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The cell selection and reselection parameters are segmented into multiple distinct sets, each tailored to specific terminal capability characteristics. The base station configures different parameter sets based on terminal categories (e.g., high-capability terminals vs. legacy terminals), allowing differentiated optimization without requiring a single complex universal parameter set. This segmentation enables efficient matching between terminal capabilities and parameter configurations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention applies parameter changes by dynamically adjusting cell selection and reselection parameters based on terminal capability information. The base station modifies parameters such as measurement thresholds, reselection offsets, and frequency priorities according to the specific capabilities of terminals, thereby optimizing communication efficiency for different terminal types while managing configuration complexity through capability-based parameter adaptation.

Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The invention extracts and transmits only the necessary parameter sets to terminals based on their capability matching. Instead of transmitting all possible parameter sets, the base station identifies the most appropriate parameter set for each terminal's capabilities and transmits only that specific set, thereby reducing signaling overhead while maintaining high data transmission rates. This selective extraction approach minimizes redundant information transfer.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The base station performs preliminary matching between terminal capability information and available parameter sets before transmission. By pre-configuring multiple parameter sets and establishing correspondence relationships with terminal capabilities in advance, the base station can quickly identify and transmit the appropriate parameter set without extensive real-time signaling, thereby reducing overall signaling overhead while ensuring optimal data transmission performance.
