Engineering Contradiction Analysis
1Reliability
If beam indication information is introduced to indicate whether the same or different beams are adopted for N signals, then signal transmission performance is improved, but device complexity increases
Solution Approach 1:
The network device performs preliminary beam indication by sending beam indication information to the terminal device before actual signal transmission. This preliminary action allows the terminal device to determine whether to use the same or different beams for receiving N signals in advance, optimizing signal transmission performance without adding complex real-time decision-making mechanisms during transmission.
Solution Approach 2:
The patent implements a feedback mechanism where the terminal device sends first indication information back to the network device after receiving beam indication information. This feedback loop enables the network device to understand which beam configuration (same or different beams) the terminal device selected, allowing for optimized subsequent transmissions and improving overall signal transmission performance.
2Measurement precision
If the terminal device adopts different beams to receive N signals, then signal detection performance is improved, but device complexity increases
Solution Approach 1:
The patent enables dynamic beam selection at the terminal device. Based on the received beam indication information, the terminal device dynamically determines whether to use the same beam or different beams for receiving N signals. This dynamic approach allows the system to adapt to varying channel conditions and signal requirements, improving signal detection performance while managing device complexity through algorithmic decision-making rather than hardware complexity.
