Title:
DATA TRANSMISSION METHOD, AND DEVICE AND SYSTEM RELATED THERETO
Document Type and Number:
WIPO Patent Application WO/2019/184574
Kind Code:
A1
Abstract:
A data transmission method, and a device and system related thereto. The method comprises: a network device transmitting a synchronization signal/physical broadcast channel (SS/PBCH) block after a listen before talk (LBT) process, an actual time position at which the SS/PBCH block is transmitted being a preset time position in a synchronization signal burst set window corresponding to the SS/PBCH block, the synchronization signal burst set window comprising a plurality of preset time positions corresponding to each of one or more SS/PBCH blocks. The above solution enables a network device to transmit SS/PBCH blocks at multiple possible positions after an LBT process succeeds, thereby increasing the probability of successfully transmitting the SS/PBCH blocks at preset time positions.
