1Area of stationary object
If the network device sends multiple different beams to enhance signal coverage, then the signal coverage is improved, but it becomes difficult to determine and indicate the optimal beam to the UE
Solution Approach 1:
The network device sends multiple beams and receives feedback from the UE about which beam is best received. The UE measures the quality of multiple received beams and reports back to the network device, enabling the network to identify the optimal beam for subsequent communication based on actual channel conditions
Solution Approach 2:
The UE autonomously determines the best beam from multiple received beams based on its own measurements of signal quality. The UE performs self-evaluation of different beam qualities and selects the optimal beam without requiring complex network-side determination, simplifying the overall system complexity
2Reliability
If the network device indicates the best beam to the UE, then the communication quality is ensured, but the beam indication process adds system complexity
Solution Approach 1:
The patent uses reference signals as an intermediary to facilitate beam indication. The network device transmits reference signals through different beams, and the UE measures these reference signals to determine beam quality. This intermediary mechanism enables reliable beam selection while keeping the indication process manageable
Solution Approach 2:
The patent changes the parameter representation of beam information by using reference signal measurements and quality metrics instead of direct beam identification. This parameter transformation simplifies the beam indication process while maintaining communication quality through quantitative assessment of beam performance
