Abstract: A detection method and apparatus, a terminal, and a storage medium are provided. The method includes that: a decoding parameter in a process that a decoder of a Narrowband Physical Downlink Control Channel (NPDCCH) decodes Downlink Control Information (DCI), a comparison parameter obtained by comparing an encoding result obtained by reversely encoding the decoded DCI by an encoder of the NPDCCH with the DCI before decoding, and a Signal-to-Noise Ratio (SNR) of the DCI are acquired; in a case where the decoding parameter, the comparison parameter and the SNR satisfy a first valid condition, a data transmission repetition number and a search space length of the NPDCCH are acquired; and in a case where the search space length matches the number of subframes corresponding to the data transmission repetition number, it is determined that the DCI is valid.
