Abstract: When a terminal switches from a downlink subframe to an adjacent uplink subframe, generating a first guard period, where that the terminal does not process any signal in the first guard period is defined, that is, the terminal neither receives downlink data nor sends an uplink signal in the first guard period, and therefore uncertainty of a terminal behavior during a downlink-to-uplink switching process of the terminal is avoided, and successful sending of the uplink subframe can be ensured; and when the terminal switches from an uplink subframe to a downlink subframe, generating a second guard period, where the second guard period overlaps the uplink subframe or the downlink subframe, and that the terminal does not process any signal in the second guard period is defined, and therefore uncertainty of a terminal behavior during an uplink-to-downlink switching process of the terminal is avoided.
