Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication technologies use a single RSRP threshold for all UEs, disregarding varying antenna configurations, leading to inaccurate retransmission decisions for UEs with different measurement errors, affecting signal coverage performance.
Innovation Solution
Determine distinct parameter thresholds for UEs with different antenna configurations based on their measurement accuracy and error, ensuring accurate signal quality assessment and operation alignment with their specific configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the same RSRP threshold is configured for all UEs, then the device complexity is reduced, but the measurement precision deteriorates for UEs with different antenna configurations
Solution Approach 1:
The patent applies local quality by configuring different RSRP thresholds for different UE antenna configurations. Specifically, UEs with 1RX antenna configuration are assigned a first RSRP threshold, while UEs with 2RX antenna configuration are assigned a second RSRP threshold. This allows each UE type to have a threshold optimized for its specific measurement characteristics, thereby improving measurement precision without significantly increasing system complexity.
2Ease of operation
If the same RSRP threshold is configured for all UEs, then the ease of operation is improved, but the reliability deteriorates for UEs with large measurement errors
Solution Approach 1:
The patent improves retransmission decision reliability by applying local quality through UE-specific threshold configuration. UEs with 1RX antenna configuration (which have larger measurement errors) use a first RSRP threshold, while UEs with 2RX antenna configuration (which have smaller measurement errors) use a second RSRP threshold. This ensures that each UE type makes retransmission decisions based on thresholds appropriate to its measurement accuracy, thereby improving overall reliability.
3Measurement precision
If distinct parameter thresholds are determined for UEs with different antenna configurations, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The patent applies parameter changes by modifying the RSRP threshold parameter based on UE antenna configuration. The network device determines different threshold values (first RSRP threshold for 1RX UEs, second RSRP threshold for 2RX UEs) and configures them accordingly. This parameter differentiation improves measurement precision while keeping the complexity manageable through systematic threshold assignment rules.

AI summary
A threshold determination method is provided. The method includes: determining a numerical value corresponding to a user equipment (UE); determining a parameter threshold of the UE based on the numerical value; and performing a corresponding operation based on a size relationship between a first measurement value corresponding to a reference signal and the parameter threshold.
