Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in efficiently performing downlink reception and transmission in cellular mobile communications, particularly in scenarios requiring enhanced Mobile BroadBand (eMBB), massive Machine Type Communication (mMTC), and Ultra Reliable and Low Latency Communication (URLLC).
Innovation Solution
The implementation of a terminal device and communication method that utilizes specific radio parameters, including subcarrier spacing, OFDM symbols, and beam management to optimize downlink reception and transmission processes, such as through the use of reference and actual subcarrier spacing, synchronization signals, and beam pairing for efficient communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple communication scenarios (eMBB, mMTC, URLLC) are supported in a single technology framework, then versatility is improved, but system complexity increases
Solution Approach 1:
The patent implements a universal downlink reception framework that handles multiple communication scenarios (eMBB, mMTC, URLLC) through a single technology framework. The base station and terminal use unified procedures for receiving downlink control information and data across different scenarios, eliminating the need for separate processing paths for each scenario type.
Solution Approach 2:
The patent employs parameter changes by configuring different downlink control information parameters (such as search space configurations, resource allocation parameters, and timing parameters) to accommodate different communication scenarios. This allows the system to adapt to various scenario requirements by modifying parameters rather than changing the fundamental system architecture.
2Productivity
If downlink reception efficiency is improved through optimized radio parameters, then productivity is improved, but device complexity increases
Solution Approach 1:
The patent applies preliminary action by having the base station configure downlink control information parameters in advance through higher-layer signaling. The terminal device receives and stores these configurations before actual downlink reception occurs, allowing efficient processing during data transmission without real-time calculation overhead.
Solution Approach 2:
The patent introduces configuration messages as an intermediary layer between the base station and terminal device. These configuration messages carry pre-defined parameters that mediate the complex interaction between different communication scenarios and terminal capabilities, simplifying the terminal's processing burden while maintaining high reception efficiency.
