18. A network side device for determining a reference subframe, comprising:
a processor;
a hardware memory, which is connected with the processor via a bus interface and is configured to store program and data used for the processor;
a transceiver, which is configured to communicate with other devices through transmission media,
when the processor calls and executes the program and data stored in the hardware memory, the network side device realizes the following steps:
determining at least two downlink CSI measurement subframe sets configured for a User Equipment (UE);
determining that the downlink CSI measurement subframe set meets a predetermined condition, wherein the predetermined condition is set as: there is no downlink Aperiodic CSI (A-CSI) reference subframe within a range [subframe n−k1, subframe n−k2] which belongs to the downlink CSI measurement subframe set, a subframe n being an uplink subframe for transmitting A-CSI by the UE, the subframe n−k1 being a downlink subframe for transmitting A-CSI triggering signaling, where k1 and k2 being each a positive integer, and where k1≥k2; and
with respect to one of the at least two downlink CSI measurement subframe sets, determining a serial number of a downlink A-CSI reference subframe in the downlink CSI measurement subframe set in accordance with a predetermined rule, and determining the downlink A-CSI reference subframe in accordance with the determined serial number of the downlink A-CSI reference subframe.
