1. A communication method, comprising:
receiving first Downlink Control Information (DCI) and second DCI within a time unit n, the first DCI scheduling a first Physical Downlink Shared Channel (PDSCH), the second DCI scheduling a second PDSCH, the first DCI containing first indication information indicating a timing of an uplink feedback resource corresponding to the first PDSCH, and the second DCI containing second indication information indicating that a timing of an uplink feedback resource corresponding to the second PDSCH is to be determined; and
determining, when the first PDSCH and the second PDSCH belong to a same PDSCH group, the timing of the uplink feedback resource corresponding to the second PDSCH based on a Counter Downlink Allocation Indicator (C-DAI) in the first DCI and a C-DAI in the second DCI,
wherein said determining the timing of the uplink feedback resource corresponding to the second PDSCH based on the C-DAI in the first DCI and the C-DAI in the second DCI comprises:
determining, when the C-DAI in the first DCI is located before the C-DAI in the second DCI, the timing of the uplink feedback resource corresponding to the second PDSCH by detecting a third DCI, the third DCI indicating the timing of the uplink feedback resource corresponding to the PDSCH group to which the second PDSCH belongs; or
determining, when the C-DAI in the first DCI is located after the C-DAI in the second DCI, the timing of the uplink feedback resource corresponding to the second PDSCH to be same as the timing of the uplink feedback resource corresponding to the first PDSCH.
