Engineering Contradiction Analysis
1Reliability
If multiple antenna panels are used for transmitting synchronization signal blocks, then coverage and reliability are improved, but device complexity increases
Solution Approach 1:
The transmitting device divides synchronization signal blocks across multiple antenna panels, with each panel transmitting a separate synchronization signal block. The receiving device similarly uses multiple antenna panels to receive these signals independently, then combines them to improve reliability. This segmentation allows the system to achieve diversity gain and coverage extension without requiring complex beamforming coordination between panels.
2Area of stationary object
If multiple antenna panels are used for transmitting synchronization signal blocks, then coverage area is expanded, but signal strength determination becomes more difficult
Solution Approach 1:
The receiving device measures the signal strength of each received synchronization signal block from different antenna panels and uses this feedback information to determine the strongest signal source. The system compares signal strength metrics (such as RSRP) across multiple received blocks and selects the corresponding transmitting device for synchronization, ensuring accurate measurement despite multiple transmission sources.
3Productivity
If multiple antenna panels are used for synchronization signal block transmission, then synchronization efficiency is improved, but the lack of standardized methods increases implementation difficulty
Solution Approach 1:
The patent establishes a universal method applicable to all devices using multiple antenna panels for synchronization signal block transmission. The standardized procedure allows any compliant device to transmit and receive synchronization signals using multiple panels according to the same rules, enabling interoperability and simplifying implementation across different manufacturers and device types despite the inherent complexity of multi-panel configurations.

AI summary
A synchronization signal block transmission method, a device and a storage medium thereof are provided. The method includes that a first device including n antenna panels uses k antennal panels of the n antenna panels for receiving a synchronization signal block sent by at least one antenna panel of at least one second device, where n is an integer greater than or equal to 2. Additionally, in accordance with signal strength of each synchronization signal block received by each of the k antenna panels, the first device determines, from the at least one second device, a target second device for carrying out synchronization.
