A full-duplex transmission control method, comprising: obtaining, by a user equipment, a first time resource unit (Step 101); if the user equipment obtains, from the first time resource unit, a comprised scheduling grant information indicating a full-duplex transmission, correcting, by the user equipment according to a power offset obtained by the user equipment, a first uplink transmission power used for a half-duplex transmission, to obtain a second uplink transmission power used for the full-duplex transmission (Step 102); and a transmitting, by the user equipment, an uplink signal in the first time resource unit or a second time resource unit according to the second uplink transmission power, wherein the second time resource unit is a time resource unit that is after the first time resource unit in terms of time (Step 103), wherein the first and second time resource units each comprise a subframe, a frame, a timeslot, and an orthogonal frequency division multiplexing OFDM symbol; characterized in that the obtaining, by a user equipment, a first time resource unit comprises: detecting, by the user equipment in the first time resource unit, whether there is an uplink feedback information corresponding to a downlink data information transmission in a fifth time resource unit that is before the first time resource unit, and detecting, in the first time resource unit or a fourth time resource unit that is before the first time resource unit, whether there is a downlink scheduling information indicating to perform transmission in the first time resource unit or the second time resource unit, wherein the fourth time resource unit and the fifth time resource unit are two different time resource units; and if the uplink feedback information corresponding to the downlink data information transmission in the fifth time resource unit is detected in the first time resource unit, a quantity of time resource units between the first time resource unit and the fifth time resource unit meets a preconfigured difference value, and the downlink scheduling information is detected in the first time resource unit or the fourth time resource unit, determining that the first time resource unit comprises scheduling information indicating the full-duplex transmission; or if the uplink feedback information is not detected in the first time resource unit, a quantity of time resource units between the first time resource unit and the fifth time resource unit does not meet a preconfigured difference value, or the downlink scheduling information is not detected in the first time resource unit or the fourth time resource unit, determining that the first time resource unit does not comprise information about the full-duplex transmission. obtaining, by a user equipment, a first time resource unit (Step 101); if the user equipment obtains, from the first time resource unit, a comprised scheduling grant information indicating a full-duplex transmission, correcting, by the user equipment according to a power offset obtained by the user equipment, a first uplink transmission power used for a half-duplex transmission, to obtain a second uplink transmission power used for the full-duplex transmission (Step 102);
