Provided in embodiments of the present invention are a half-duplex frequency-division duplex communication method, a base station, and a terminal, comprising: when a terminal is switching from a downlink subframe over to an adjacent uplink subframe, a first guard time is generated, by defining that the terminal does not process any signal in the first guard time, that is, the terminal neither receives downlink data nor transmits uplink signal in the first guard time, uncertainty about terminal behaviors is prevented while the terminal is in the process of switching from a downlink to an uplink, and successful transmission of the uplink subframe can be ensured; when the terminal is switching from an uplink subframe to a downlink subframe, a second guard time is generated, the second guard time overlaps either the uplink subframe or the downlink subframe, by defining that the terminal does not process any signal in the second guard time, uncertainty about terminal behaviors is prevented while the terminal is in the process of switching from the uplink over to the downlink. By providing new definitions to terminal behaviors, the embodiments of the present invention allow normal transmission and reception of data to be ensured for a network and a terminal. |
