Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the LTE system, there is a challenge in configuring an unlicensed cell to provide efficient service to user equipment due to spectrum resource shortages and increased mobile data traffic, which affects network capacity and data transmission efficiency.
Innovation Solution
A method for user equipment to receive measurement configurations from a base station, including trigger conditions, average signal strength, and signal strength-related time ratios, to report measurement results when certain thresholds are met, allowing the base station to determine channel quality and configure the unlicensed spectrum cell for service provision. Additionally, the method involves controlling a DRX timer to identify PDCCH-subframes and optimize data transmission in unlicensed spectrum cells.

1Productivity
If unlicensed spectrum cells are configured to provide service to UE, then network capacity and data transmission efficiency are improved, but channel quality assessment and service reliability become difficult to guarantee
Solution Approach 1:
The patent replaces traditional mechanical timing mechanisms with a timer-based DRX (Discontinuous Reception) mechanism that operates through standardized timing relationships. The timer is configured with specific durations and triggers based on PDCCH subframe detections, replacing ad-hoc timing decisions with a systematic, reproducible timing structure that ensures reliable operation across different unlicensed spectrum cells.
Solution Approach 2:
The patent dynamically adjusts timer configuration parameters based on detected PDCCH subframe patterns. When PDCCH subframes are detected in specific subframes, the timer duration and triggering conditions are modified to match the actual service provision patterns of the unlicensed cell, thereby adapting the timing mechanism to varying channel conditions and service requirements while maintaining reliability.
2Measurement precision
If measurement reporting is implemented for unlicensed spectrum cells, then channel quality assessment capability is improved, but measurement configuration complexity and signaling overhead increase
Solution Approach 1:
The patent creates a universal measurement reporting framework that handles multiple measurement types (signal strength, signal quality, channel resource quality) through a single unified configuration structure. The same measurement configuration template can be applied to different unlicensed spectrum cells regardless of their specific characteristics, reducing configuration complexity while maintaining comprehensive channel quality assessment capabilities across diverse scenarios.

AI summary
The present application discloses a measurement result reporting method, a method for controlling a discontinuous reception (DRX) timer to count, an apparatus, and user equipment. The measurement result reporting method includes: receiving, by user equipment, a measurement configuration of an unlicensed spectrum cell sent by a base station, where the measurement configuration includes a trigger condition, an average signal strength, and a signal strength related time ratio; and sending, by the user equipment, a measurement result of the average signal strength and the signal strength related time ratio to the base station when at least one of the average signal strength or the signal strength related time ratio satisfies the trigger condition.
