11 . A method for information transmission, applied to an access point (AP), the method comprising:
receiving a block ACK message (BA) frame, wherein the BA frame is determined by a station (STA) based on a number of a plurality of data frames transmitted continuously, wherein the data frames are a plurality of data frames sent via a single connection or a plurality of data frames sent via a plurality of connections, wherein the BA frame at least comprises feedback information with a size greater than 256 bits, wherein the feedback information is a bitmap indicating a receiving status of the data frames and one bit in the bitmap corresponds to one data frame, and the BA frame further comprises at least one of transmission connection information, traffic identifier (TID) information or STA information of data frames failing to be received,
wherein the method further comprises:
sending a BA request comprising first indication information in response to the number of the data frames transmitted being greater than or equal to a number threshold, and
wherein receiving the BA frame, comprises:
receiving the BA frame at least comprising the feedback information with the size greater than 256 bits sent by the STA according to the received BA request comprising the first indication information indicating the feedback information with the size greater than 256 bits.
