[0039] figure 1 It shows a schematic diagram of the HARQ configuration and feedback process in the prior art. At present, the base station first schedules a fixed data resource for transmitting confirmation information through the Physical Downlink Control Channel (PDCCH), and then the base station is in the downlink The physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) transmits data, and the ACK or NACK corresponding to the data transmitted by the PDSCH is in the fixed physical uplink control channel (Physical Uplink Control Channel, PUCCH) or physical uplink shared channel. (Physical Uplink Shared Channel, PUSCH). When the UE decodes the wrong data, the UE sends detailed NACK information to the base station. And in the LTE system, in order to avoid collision or overlap with system information, Multimedia Broadcast Multicast Service Single Frequency Network (MBSFN) subframes and other transmissions, data retransmission may occur at any time. And any ...
