Engineering Contradiction Analysis
1Productivity
If reference signals are multiplexed using multiple OAM modes, then data transmission rate is improved, but receiver complexity increases
Solution Approach 1:
The reference signals are segmented into different OAM modes (first OAM mode and second OAM mode), with each mode carrying reference signals for specific resource blocks. This segmentation allows the receiver to process different OAM modes separately, reducing overall receiver complexity while maintaining high data transmission rates through parallel processing of multiple modes.
Solution Approach 2:
The patent introduces OAM mode as an additional dimension for reference signal multiplexing, beyond traditional time and frequency domains. By allocating reference signals to different OAM modes, the system achieves higher transmission rates without proportionally increasing receiver complexity, as the OAM dimension provides orthogonal separation that simplifies signal processing.
2Measurement precision
If reference signals are allocated on specific resources using predetermined sequences, then resource allocation accuracy is improved, but system complexity increases
Solution Approach 1:
The patent establishes predetermined sequences for allocating reference signals to different OAM modes and resource blocks before actual transmission. This preliminary allocation scheme enables the receiver to accurately determine which resources carry reference signals for which OAM modes, improving resource allocation accuracy while avoiding the need for complex real-time allocation decisions.
3Productivity
If synchronization signal blocks are transmitted using OAM modes, then spectrum efficiency is improved, but transmission complexity increases
Solution Approach 1:
The patent makes the OAM mode allocation mechanism universal, where the same predetermined sequence and resource allocation principles apply to both reference signals and synchronization signal blocks. This multi-functionality allows the system to achieve high spectrum efficiency for synchronization transmissions without creating separate complex transmission procedures, as the existing OAM framework handles both signal types.
