Innovation Solution
A method for reporting terminal processing capabilities, including determining and sending information about three processing capabilities (first, second, and third capabilities) to network devices, allowing network devices to configure appropriate processing capabilities for eRedCap terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If existing wireless communication standards are used, then terminal processing capabilities are fixed and standardized, but terminal costs cannot be reduced through processing time relaxation
Solution Approach 1:
The terminal processing capability is segmented into multiple discrete levels (first, second, and third processing capabilities), each with distinct processing time characteristics. This segmentation allows the system to select appropriate capability levels based on terminal requirements, enabling cost reduction through relaxed processing times while maintaining adaptability through multiple capability options.
Solution Approach 2:
The terminal processing capability is made dynamic through the capability indication mechanism. The terminal can indicate its supported processing capability level to the network device, allowing the system to adaptively adjust processing time requirements based on the terminal's actual capabilities. This dynamic adaptation enables cost optimization without sacrificing necessary adaptability.
2Ease of manufacture
If processing time is relaxed for eRedCap terminals, then terminal costs are reduced, but existing standards lack effective means to support and configure these relaxed capabilities
Solution Approach 1:
The capability indication mechanism serves multiple functions: it identifies terminal types (eRedCap vs. conventional), indicates supported processing capability levels, and enables network-side configuration decisions. This multi-functionality reduces the need for separate signaling mechanisms, thereby avoiding increased device complexity while supporting relaxed processing times for cost reduction.
Solution Approach 2:
The invention changes the processing time parameter from a fixed standard value to a variable that can be adjusted based on terminal capability indications. By introducing capability levels with different processing time characteristics (first, second, third capabilities), the system can optimize terminal costs through parameter relaxation while maintaining manageable configuration complexity through standardized indication procedures.
3Adaptability or versatility
If multiple processing capability levels are defined, then adaptability to different terminal requirements is improved, but system complexity increases
Solution Approach 1:
The terminal indicates its processing capability level partially - only the highest supported capability level needs to be indicated rather than all supported levels. This partial action approach maintains high adaptability (supporting multiple capability levels) while reducing system complexity (simpler indication and management procedures).

AI summary
A method for reporting a terminal processing capability, a data processing method, and apparatuses are applicable to a new radio (NR) system. The reporting method for reporting a terminal processing capability includes: determining the terminal processing capability supported by the terminal; and sending information indicating the terminal processing capability supported by the terminal to a network device. The terminal is an enhanced reduced capability (eRedCap) terminal; and the terminal processing capability includes at least one of a first processing capability, a second processing capability or a third processing capability, wherein the first processing capability is lower than the second processing capability, and the third processing capability is lower than the first processing capability.
