Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If repeated transmission in the time domain is used to improve network coverage performance, then coverage performance is improved, but spectrum resource utilization decreases and additional delay is introduced
Solution Approach 1:
The patent combines multiple DMRS from different slots or repeated transmissions into a joint channel estimation process. By merging the reference signals across multiple time instances, the system achieves better channel estimation accuracy without requiring additional repeated transmissions, thus improving coverage performance while maintaining spectrum resource utilization.
Solution Approach 2:
The patent performs channel estimation using DMRS bundling across slots or repeated transmissions before actual data transmission. This preliminary channel estimation allows the system to compensate for channel variations in advance, improving coverage performance without introducing additional delay during the data transmission phase.
2Measurement precision
If joint channel estimation using DMRS bundling across slots or repeated transmissions is performed to improve channel estimation accuracy, then channel estimation accuracy is improved, but power consistency and phase continuity become challenging to maintain
Solution Approach 1:
The patent introduces configuration information that allows dynamic adjustment of DMRS bundling parameters such as time range, frequency range, and resource indicators. By changing these parameters based on channel conditions, the system can maintain power consistency and phase continuity while achieving accurate channel estimation across slots or repeated transmissions.
Solution Approach 2:
The patent enables dynamic configuration of joint channel estimation parameters through network device control. The configuration information can be adjusted in real-time to maintain power consistency and phase continuity requirements, allowing the system to adapt to changing channel conditions while preserving the reliability needed for accurate channel estimation.
