Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power control schemes for sparse data transmission in URLLC traffic face measurement errors due to outdated TPC commands and fail to achieve power efficiency and interference control in scenarios with frequent data transmission.
Innovation Solution
A method is introduced to determine whether a first transmit power control configuration is outdated, and a second configuration is set using a close loop or open loop power control scheme, with the option to switch between them based on timer expiration or network indications, ensuring accurate power control for current uplink transmissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If TPC command accumulation is enabled for frequent data transmission, then transmit power control efficiency is improved, but measurement precision deteriorates due to outdated TPC commands in sparse transmission scenarios
Solution Approach 1:
The patent applies dynamics by making the power control configuration adaptive rather than static. The network device dynamically selects between accumulation-enabled and accumulation-disabled configurations based on current transmission conditions. When data transmission is frequent, accumulation is enabled for high efficiency; when transmission is sparse, accumulation is disabled to maintain measurement precision. This dynamic adaptation resolves the contradiction between efficiency and precision.
Solution Approach 2:
The patent changes the parameter of TPC command accumulation status between two states (enabled/disabled) based on transmission characteristics. By switching this parameter according to whether data transmission is frequent or sparse, the system achieves both high power control efficiency during frequent transmission and accurate measurement during sparse transmission, resolving the technical contradiction.
2Measurement precision
If TPC command accumulation is disabled for sparse data transmission, then measurement precision is maintained, but transmit power control efficiency deteriorates in scenarios with frequent data transmission
Solution Approach 1:
The system dynamically adjusts the accumulation status based on transmission frequency. For sparse transmissions, accumulation is disabled to maintain precision; for frequent transmissions, accumulation is enabled to improve efficiency. This dynamic behavior allows the system to optimize for the appropriate metric based on current conditions.
Solution Approach 2:
The accumulation-enabled parameter is changed based on transmission characteristics. When transmission is sparse, the parameter is set to disabled for precision; when transmission is frequent, the parameter is set to enabled for efficiency. This parameter switching resolves the contradiction between precision and efficiency.
3Device complexity
If a single power control configuration is used for all transmission scenarios, then device complexity is reduced, but adaptability deteriorates due to inability to handle both frequent and sparse transmissions optimally
Solution Approach 1:
The patent implements multi-functionality by creating a power control system that can operate in two modes (accumulation-enabled and accumulation-disabled) within a single configuration framework. The same power control mechanism serves both frequent transmission scenarios (with accumulation for efficiency) and sparse transmission scenarios (without accumulation for precision), making the system universally applicable to different transmission patterns without requiring separate systems.
Solution Approach 2:
The system dynamically adapts its configuration based on transmission characteristics. Rather than using a fixed single configuration, the system adjusts between accumulation-enabled and accumulation-disabled modes according to whether transmission is frequent or sparse. This dynamic adaptability allows the system to handle diverse scenarios optimally while maintaining a unified configuration structure.
