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, the first radio signal is a Primary Synchronization Signal (PSS), the first radio signal is generated by a pseudo-random sequence; and
transmitting a first signaling, the first signaling is carried by Secondary Synchronization Signal (SSS);
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 transmission bandwidth of the first carrier is variable, the first carrier includes transmission frequency-domain resources and guard frequency-domain resources; 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, the first frequency band is a Time Division Duplexing (TDD) frequency band; 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), which means that the first frequency interval is linearly 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 cell 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, a subcarrier spacing of the X subcarrier(s) is one of 15 kHz, 30 kHz, 120 kHz, 240 kHz or 480 kHz; and the Y is a positive integer; the first frequency domain resources are contiguous in the frequency domain, the first time window includes W consecutive OFDM symbols in time domain, W being a positive integer.
