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, by the macro base station, a signal in a first downlink timeslot used by the macro base station; receiving, 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, 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, by the pico base station, a signal in the first downlink timeslot used by the pico base station; and receiving, 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, by the macro base station, a signal in a first downlink timeslot used by the macro base station; receiving, 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, 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, by the pico base station, a signal in the first downlink timeslot used by the pico base station; and receiving, by the pico base station, a signal in the first uplink timeslot used by the pico base station; wherein performing, 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, by the pico base station, a signal in the first downlink timeslot used by the pico base station; and receiving, 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.
