Provided are time domain resource determination and detection methods and apparatuses, a storage medium and an electronic device. The method includes determining a time domain resource allocation pattern set. The time domain resource allocation pattern set includes at least one of a time domain resource allocation pattern set corresponding to a combination of a first subcarrier spacing (SCS) and a second SCS, where the first SCS is an SCS of a first channel signal, and the second SCS is an SCS of a second channel signal; a time domain resource allocation pattern set indicated by downlink control information (DCI) signaling; or a time domain resource allocation pattern set corresponding to a slot type. A time domain resource allocation pattern in the time domain resource allocation pattern set is used to indicate symbols occupied by the second channel signal.
