               1. A method for retransmission feedback, performed by a request end, comprising: 
            generating a request frame for establishing a retransmission feedback mechanism; 
                sending the request frame; 
                receiving a response frame returned based on the request frame and for establishing the retransmission feedback, wherein the response frame comprises first configuration information for performing retransmission feedback, 
                wherein the request frame comprises second configuration information for requesting data frame transmission, 
                  wherein the response frame further comprises third configuration information generated based on the second configuration information, 
                  wherein the third configuration information comprises at least one of: 
                second type information of the data frame, wherein the second type information is used to indicate the data frame is a single data frame or a continuous data frame, 
                    second frequency band information of the data frame, or 
                    second beam information of the data frame; and 
                  sending the data frame according to the third configuration information, 
              wherein when the second type information indicates that the data frame is a continuous data frame, the third configuration information further comprises second quantity information of sub-data frames included in the continuous data frame; the second quantity information is determined according to a number of sub-data frames included in the continuous data frame which is requested by the request frame, and 
                  wherein sending the data frame according to the third configuration information comprises: 
                sending sub-data frames of a quantity indicated by the second quantity information.
