1. A method for indicating a time difference between a Physical Uplink Control Channel (PUCCH) and a Physical Downlink Shared Channel (PDSCH), comprising:
transmitting the PDSCH to a User Equipment (UE);
determining whether a PDSCH-to-HARQ-timing-indicator field indicates the time difference between the PDSCH and the PUCCH used to feed back HARQ-ACK, to obtain an indication result;
generating an index value of the PDSCH-to-HARQ-timing-indicator field in downlink control information based on the indication result; and
indicating to the UE the index value of the PDSCH-to-HARQ-timing-indicator field in the downlink control information;
wherein the PDSCH-to-HARQ-timing-indicator field not indicating the time difference between the PDSCH and the PUCCH used to feed back HARQ-ACK makes the UE wait for subsequent explicit indication information for performing a HARQ-ACK feedback to the PDSCH received by the UE.
