1. A method for allocating time domain resources, applied to a base station, the method comprising:
transmitting downlink control information, DCI, signaling by the base station, the DCI signaling being configured to indicate a time domain resource used by a terminal to perform physical uplink shared channel (PUSCH) transmission, the time domain resource comprising two or more slots, or two or more mini-slots, or both two or more slots and two or more mini-slots;
wherein the DCI signaling is further configured to indicate a starting symbol, or an ending symbol, or both the starting symbol and the ending symbol of the time domain resource; the starting symbol being configured to indicate a starting symbol of the PUSCH transmission performed by the terminal, and the ending symbol being configured to indicate an ending symbol of the PUSCH transmission performed by the terminal;
the DCI signaling comprises at least one of one starting symbol of the time domain resource or one ending symbol of the time domain resource, wherein the one starting symbol is configured to indicate the starting symbol of each of the two or more slots; and the one ending symbol is configured to indicate the ending symbol of each of the two or more slots; or
the DCI signaling comprises one starting symbol of the time domain resource and one symbol number, wherein the one starting symbol is configured to indicate the starting symbol of a first one of the two or more mini-slots, and the one symbol number is configured to indicate the number of symbols included in each of the two or more mini-slots and the starting symbol of an Sth mini-slot is adjacent to the ending symbol of a (S−1)th mini-slot, where S is an integer greater than 1,
wherein in response to the time domain resource being two or more slots, a scheduling mode of the time domain resource is scheduling based on each slot, a stopping position of a listen before talk (LBT) monitoring is before a starting symbol of a last slot of the two or more slots, and in response to the time domain resource being two or more mini-slots, a scheduling mode of the time domain resource is scheduling based on each mini-slot, a stopping position of the LBT monitoring is a starting symbol of a last mini-slot of the two or more mini-slots.
