Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The NR-light terminal faces challenges in meeting diverse application scenario requirements for communication systems, such as high rates and low delays, while maintaining reduced complexity and cost.
Innovation Solution
The terminal reports a capability parameter set to the network device, which determines a capability parameter subset matching the business requirements and sends corresponding schedule information, allowing the terminal to perform communication efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the terminal supports diverse application scenarios with different service requirements, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The terminal capability parameters are segmented into multiple independent parameters (e.g., maximum subcarrier spacing, maximum symbol length, processing capability parameters) that can be selectively reported and configured. This allows the system to activate only the necessary segments for each application scenario, improving adaptability while controlling complexity.
Solution Approach 2:
The terminal capability configuration is made dynamic through the network device's ability to determine and send appropriate capability parameter subsets based on current service requirements. The terminal can adapt its operational parameters dynamically according to the scheduled service type, rather than maintaining fixed high-complexity capabilities for all scenarios.
2Productivity
If the terminal is configured to meet high rate and low delay requirements, then the productivity is improved, but the device complexity increases
Solution Approach 1:
High productivity capabilities (such as large subcarrier spacing for high rate, short symbol length for low delay) are applied locally only when and where needed, as determined by the network device based on service requirements. The terminal maintains the capability to support these parameters but only activates them for specific services, achieving high productivity for critical applications while avoiding the complexity of permanently configuring all high-performance features.
3Adaptability or versatility
If the terminal reports all capability parameters, then the adaptability is improved, but the loss of information increases due to excessive reporting overhead
Solution Approach 1:
The network device extracts only the necessary capability parameters from the terminal's full capability set based on current service requirements. Instead of the terminal reporting all capability parameters universally, the system takes out and processes only the relevant subset (e.g., only processing capability parameters for URLLC services, only bandwidth parameters for eMBB services), reducing information overhead while maintaining adaptability for the specific scenario.
Data Source
AI summary
A communication method and apparatus. The communication method includes reporting a capability parameter set, in which the capability parameter set represents information on a capability supported by the terminal; and receiving first schedule information sent by a network device, in which the first schedule information includes second schedule information corresponding to a capability parameter subset, and the capability parameter subset includes a capability parameter matching a business requirement of the terminal in the capability parameter set.
