Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing technologies face a challenge of high power consumption in user equipment (UE) during data transmission in a non RRC-CONNECT state.
Innovation Solution
A data transmission method and device that allow the UE to transmit signals on specifically configured uplink channel resources, including single subcarrier signals, multi-subcarrier signals, or random access signals, to reduce power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If UE transmits data in non RRC-CONNECT state using existing methods, then data transmission can be performed, but power consumption becomes excessively high
Solution Approach 1:
The patent segments the uplink channel resources into multiple types (first type for data transmission, second type for non-contention-based random access, third type for contention-based random access). This segmentation allows the UE to select appropriate resources for different transmission scenarios, avoiding unnecessary power consumption while maintaining data transmission capability.
Solution Approach 2:
The patent introduces dynamic selection mechanisms where the UE can choose from multiple uplink channel resource types based on current transmission needs. The UE dynamically determines which resource type to use (first, second, or third type) depending on the specific data transmission requirements, optimizing power consumption while maintaining productivity.
2Adaptability or versatility
If UE uses multiple uplink channel resource types, then transmission flexibility is improved, but device complexity increases
Solution Approach 1:
The patent makes the UE capable of using multiple uplink channel resource types (first type for data transmission, second type for non-contention-based random access, third type for contention-based random access). This multi-functionality allows a single UE to handle different transmission scenarios flexibly, improving adaptability while the standardized resource types help manage complexity.
Solution Approach 2:
The patent uses parameter changes in resource configuration, where the base station provides configuration information that includes parameters for different uplink channel resource types. The UE adjusts its transmission parameters based on these configurations, enabling flexible adaptation to different scenarios while following standardized parameter sets that manage complexity.
