1. A method for detecting a downlink transmission, comprising:
receiving configuration information of the downlink transmission sent by a base station, wherein the configuration information comprises time-frequency position information of the target signal;
detecting, by a user equipment (UE), a target signal of a downlink transmission within a first detection period based on the time-frequency position information, wherein the target signal comprises at least one of following signals: a downlink demodulation reference signal, a synchronization signal, or a tracking reference signal;
determining, by the UE, whether a detection result satisfies a predetermined adjustment condition in response to detecting no target signal; and
extending, by the UE, the first detection period currently used by a physical downlink control channel to a predetermined second detection period in response to determining that the detection result satisfies the predetermined adjustment condition.
