A wireless communication method, applied to a wireless communications system in which a macro cell corresponding to a macro base station comprises a small cell corresponding to a pico base station , wherein the macro base station and the pico base station use a same carrier to respectively communicate with user equipment served by the macro base station and user equipment served by the pico base station, and the method comprises: sending (S101), by the macro base station, a signal in a first downlink timeslot used by the macro base station; receiving (S102), by the macro base station, a signal in a first uplink timeslot used by the macro base station; and skipping sending and receiving, by the macro base station, a signal in an idle timeslot used by the macro base station; wherein, the method further comprises: performing (S301), by the pico base station, one or more of signal sending or signal reception in the first full-duplex timeslot used by the pico base station, wherein the full-duplex communication permits the pico base station to perform simultaneous sending and reception operations on a same radio channel; sending (S302), by the pico base station, a signal in the first downlink timeslot used by the pico base station; and receiving (S303), by the pico base station, a signal in the first uplink timeslot used by the pico base station; wherein a starting point and an ending point of an idle timeslot used by the macro base station are aligned with those of the first full-duplex timeslot used by the pico base station, a starting point of a first downlink timeslot used by the macro base station is aligned with that of the first downlink timeslot used by the pico base station, and a starting point and an ending point of a first uplink timeslot used by the macro base station are aligned with those of the first uplink timeslot used by the pico base station. sending (S101), by the macro base station, a signal in a first downlink timeslot used by the macro base station; receiving (S102), by the macro base station, a signal in a first uplink timeslot used by the macro base station; and skipping sending and receiving, by the macro base station, a signal in an idle timeslot used by the macro base station; wherein, the method further comprises: performing (S301), by the pico base station, one or more of signal sending or signal reception in the first full-duplex timeslot used by the pico base station, wherein the full-duplex communication permits the pico base station to perform simultaneous sending and reception operations on a same radio channel; sending (S302), by the pico base station, a signal in the first downlink timeslot used by the pico base station; and receiving (S303), by the pico base station, a signal in the first uplink timeslot used by the pico base station; wherein performing (S301), by the pico base station, one or more of signal sending or signal reception in the first full-duplex timeslot used by the pico base station, wherein the full-duplex communication permits the pico base station to perform simultaneous sending and reception operations on a same radio channel; sending (S302), by the pico base station, a signal in the first downlink timeslot used by the pico base station; and receiving (S303), by the pico base station, a signal in the first uplink timeslot used by the pico base station; wherein a starting point and an ending point of an idle timeslot used by the macro base station are aligned with those of the first full-duplex timeslot used by the pico base station, a starting point of a first downlink timeslot used by the macro base station is aligned with that of the first downlink timeslot used by the pico base station, and a starting point and an ending point of a first uplink timeslot used by the macro base station are aligned with those of the first uplink timeslot used by the pico base station. <EOS>
