Claim of US Patent No. 10,925,020

1. A method for synchronization in a base station, comprising:transmitting a first radio signal on first frequency-domain resources in a first time window; and
transmitting a first signaling;
wherein a center frequency of the first frequency-domain resources is a first frequency; the first frequency-domain resources include X subcarrier(s); the X is a positive integer; a carrier to which the first frequency-domain resources belong is a first carrier; a frequency band to which the first carrier belongs is a first frequency band, a center frequency of the first carrier is a second frequency; an interval between the first frequency and the second frequency in frequency domain is a first frequency interval; the first frequency interval is related to a subcarrier spacing of the X subcarrier(s); the first radio signal is used to determine at least one of a location of the first time window in time domain or the first frequency; the first radio signal is broadcast; or the first radio signal is multicast; the first signaling is used to determine a feature ID of a transmitter of the first radio signal in the first carrier; the first frequency interval belongs to a target frequency interval set the target frequency interval set includes a positive integer number of frequency interval(s); a subcarrier spacing of the X subcarrier(s) and a location of the first frequency band in frequency domain are used to determine the target frequency interval set out of Y frequency interval sets; and the Y is a positive integer.
