A method of obtaining Hybrid Automatic Repeat reQuest, HARQ, feedback in 5G cellular communication system, which is applied in first equipment, the method comprising: configuring short Transmission Time Interval, TTI, scheduling information into a first target long TTI according to service requirements, wherein the short TTI scheduling information includes at least location information, length information, quantity information and location information of HARQ feedback resource of a short TTI, the HARQ feedback resource of the short TTI is configured to send HARQ feedback of the short TTI to the first equipment from second equipment, and the location information is to indicate a long TTI which is to be scheduled with the short TTI; sending the short TTI scheduling information to the second equipment through the first target long TTI; scheduling short TTIs in a second target long TTI according to the short TTI scheduling information, and sending a data packet in each of the scheduled short TTIs within the second target long TTI to the second equipment; and receiving HARQ feedback from the second equipment, wherein the HARQ feedback corresponds to the data packet in each of the scheduled short TTIs within the second target long TTI which is sequentially obtained by the second equipment; characterized in that, wherein configuring the location information of HARQ feedback resource of a short TTI in the first target long TTI comprises: configuring a HARQ feedback resource of each short TTI to be immediately adjacent to a tail of the short TTI; or when a long TTI has redundant resources after the short TTIs are scheduled in the long TTI, assigning a last one of the one or more short TTIs a HARQ feedback resource originally configured for the long TTI. configuring short Transmission Time Interval, TTI, scheduling information into a first target long TTI according to service requirements, wherein the short TTI scheduling information includes at least location information, length information, quantity information and location information of HARQ feedback resource of a short TTI, the HARQ feedback resource of the short TTI is configured to send HARQ feedback of the short TTI to the first equipment from second equipment, and the location information is to indicate a long TTI which is to be scheduled with the short TTI; sending the short TTI scheduling information to the second equipment through the first target long TTI; scheduling short TTIs in a second target long TTI according to the short TTI scheduling information, and sending a data packet in each of the scheduled short TTIs within the second target long TTI to the second equipment; and receiving HARQ feedback from the second equipment, wherein the HARQ feedback corresponds to the data packet in each of the scheduled short TTIs within the second target long TTI which is sequentially obtained by the second equipment; characterized in that, wherein configuring the location information of HARQ feedback resource of a short TTI in the first target long TTI comprises: configuring a HARQ feedback resource of each short TTI to be immediately adjacent to a tail of the short TTI; or when a long TTI has redundant resources after the short TTIs are scheduled in the long TTI, assigning a last one of the one or more short TTIs a HARQ feedback resource originally configured for the long TTI. configuring a HARQ feedback resource of each short TTI to be immediately adjacent to a tail of the short TTI; or when a long TTI has redundant resources after the short TTIs are scheduled in the long TTI, assigning a last one of the one or more short TTIs a HARQ feedback resource originally configured for the long TTI.
