Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face poor communication quality due to inadequate synchronization of transmission parameters with beam switching, leading to delayed and inefficient parameter updates.
Innovation Solution
The method involves encoding and sending multiple sets of transmission parameters, including beam and quasi-co-location indications, and using a selection indication to dynamically switch parameters during beam changes, ensuring data transmission quality by keeping parameter updates aligned with beam switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If transmission parameters are updated separately from beam switching, then parameter update flexibility is maintained, but communication quality deteriorates due to parameter desynchronization
Solution Approach 1:
The patent combines beam switching and transmission parameter updates into a unified process. When beam switching occurs, the terminal device simultaneously updates transmission parameters associated with the new beam, ensuring synchronization between beam configuration and parameter configuration. This merging eliminates the desynchronization issue while maintaining manageable complexity through integrated handling.
Solution Approach 2:
The patent pre-configures multiple sets of transmission parameters corresponding to different beams before beam switching occurs. The terminal device stores these parameter sets in advance, so when beam switching is triggered, the appropriate parameters are already prepared and can be immediately applied without delay or separate update procedures, ensuring seamless synchronization.
2Reliability
If multiple sets of transmission parameters are configured for different beams, then communication quality during beam switching is improved, but signaling overhead increases
Solution Approach 1:
The patent segments transmission parameters into beam-specific groups, where each beam has its own associated parameter set. This segmentation allows the system to only activate and transmit parameters relevant to the currently active beam, reducing the amount of signaling overhead while maintaining comprehensive parameter coverage for multiple beams. The terminal device stores multiple parameter sets but only processes the active one, minimizing redundant information transmission.
3Productivity
If transmission parameters are updated dynamically during beam switching, then data transmission continuity is maintained, but parameter update timing precision becomes critical
Solution Approach 1:
The patent prepares transmission parameters in advance for each beam before switching occurs. The terminal device pre-configures parameter sets corresponding to different beams and stores them ready for immediate application. When beam switching is triggered, the pre-prepared parameters are instantly applied without requiring precise real-time synchronization, thereby maintaining data transmission continuity while reducing the criticality of timing precision.
