AI Technical Summary
Existing IoT communication technologies suffer from labor-intensive operations, time-consuming and expensive RFID deployment, and high maintenance costs and high power consumption of NB-IoT and mMTC technologies, resulting in high equipment prices and security risks.
The synchronization method employs an intermediate node user equipment (UE) between the base station and the IoT device to perform synchronization. By sending synchronization signals and preamble sequences, frequency and time synchronization is achieved, and control signaling is used to instruct carrier transmission, thereby optimizing the communication of IoT downlink and uplink.
It enables low-complexity, low-cost IoT device synchronization, reduces device maintenance costs, improves communication performance and reliability, supports long-term battery-free operation, and is suitable for densely deployed IoT devices.
