The embodiment of the invention provides a method and device for determining time domain resources, a storage medium and a system. The method comprises the following steps: receiving allocation information of to-be-scheduled time domain resources sent by network equipment, wherein the to-be-scheduled time domain resources comprise time domain resources to be subjected to channel transmission; based on a set determination rule, determining a corresponding time domain position for the to-be-scheduled time domain resources according to the uplink and downlink time domain resource configuration information and the allocation information; and performing channel transmission with the network equipment according to the time domain position corresponding to the to-be-scheduled time domain resources through the to-be-scheduled time domain resources. According to the invention, when the terminal performs channel transmission, the situation that the terminal cannot transmit the channel in a shorttime period due to conflict with the time domain configuration information is avoided, the signaling overhead of the terminal and the base station during channel transmission is saved, and the falsedetection probability rise caused by repeatedly sending the control signaling is also avoided.
