Aperiodic ZP CSI-RS resource set determination and configuration methods and devices, a storage medium, a user equipment, and a network end. The determination method comprises: receiving a PDCCH, and the PDCCH scheduling K time slots for transmitting a PDSCH; extracting from the PDCCH a preset number of bits of indication information of an aperiodic ZP CSI-RS resource set; extracting ┌log2 J┐ bits from the indication information, and determining a selected aperiodic ZP CSI-RS resource set according to an extraction result; and determining, according to a comparison result between the number of bits of the indication information and ┌log2 J┐, the position of a ZP CSI-RS resource indicated by the selected aperiodic ZP CSI-RS resource set in the K time slots. The solution of the invention enables UE to accurately determine a selected aperiodic ZP CSI-RS resource, thereby improving the accuracy of decoding.
