Abstract: A method for determining a working frequency point includes: each measurement period and each frequency point to be measured in each measurement period are acquired; whether a present moment is a first scheduling slice of a present measurement period is judged; if YES, frequency point switching and measurement are sequentially performed to obtain a Received Signal Strength Indication (RSSI) value of each frequency point to be measured in the present measurement period, frequency point switching back to a present working frequency point is performed, and the judging is re-executed until an RSSI value of each frequency point to be measured in each measurement period is measured; if NO, the judging is re-executed; and a working frequency point is redetermined according to a relationship between the RSSI value of each frequency point to be measured in each measurement period and an interference value of the present working frequency point.

Abstract: Provided is a synchronization method, which includes: a first device periodically sends a first PSS sequence and first PDSCH control information at frequency points F1 to FN in sequence, where the first PSS sequence and the first PDSCH control information are used for a second device to detect the first PSS sequence and detect the first PDSCH control information; the first device receives signals at frequency points f1 to fM in sequence and detects a second PSS sequence; when the second PSS sequence is detected, the first device obtains second half-frame synchronization information and detects second PDSCH control information according to the second half-frame synchronization information; and when the second PDSCH control information is detected, the first device obtains second frame synchronization information and enters a synchronization state. Also provided are a synchronization device, a synchronization system, and a computer-readable storage medium.
