1Area of stationary object
If multiple transmission beams are used to expand network coverage, then coverage area is improved, but signal synchronization becomes more difficult due to overlapping beams from different cells
Solution Approach 1:
The patent applies parameter changes by adjusting the power levels of synchronization signal blocks transmitted through different beams. The network dynamically configures power offsets for SS blocks in different beams, allowing the receiver to normalize and compare signal strengths across overlapping beams from different cells, thereby resolving synchronization issues while maintaining expanded coverage
Solution Approach 2:
The patent implements feedback mechanisms where the receiver measures and reports reference signal received power (RSRP) for different synchronization signal blocks, and the network uses this feedback to optimize beam power configuration. This closed-loop approach enables continuous improvement of synchronization reliability across the expanded network coverage area
2Adaptability or versatility
If different power levels are used for multiple synchronization signal blocks, then beam coverage optimization is improved, but signal interference increases
Solution Approach 1:
The patent applies local quality by assigning different power levels to synchronization signal blocks based on their specific beam directions and coverage requirements. Each beam can be configured with customized power offsets to optimize its coverage area while minimizing interference in overlapping regions, creating locally optimized signal characteristics rather than uniform transmission
Solution Approach 2:
The patent implements preliminary action by pre-configuring power offset values for different synchronization signal blocks before transmission. The network calculates and signals these power offsets to user equipment in advance, enabling the receiver to properly normalize and compare signal strengths from multiple beams, thereby reducing interference effects during signal measurement and selection
3Measurement precision
If power information is transmitted through multiple signaling channels, then power level control precision is improved, but system complexity increases
Solution Approach 1:
The patent applies universality by designing a multi-functional signaling approach where power offset information for synchronization signal blocks is conveyed through multiple existing signaling channels (system information blocks and RRC signaling). This allows a single power configuration mechanism to serve multiple purposes: beam management, handover decisions, and interference coordination, thereby achieving precise power control without proportionally increasing system complexity
