Abstract: The technology of this application relates to an optical-electrical co-package structure including a carrier circuit board, an optical-electrical conversion module, a package circuit board, and an electrical chip. The package circuit board and the optical-electrical conversion module are respectively located on a first side surface and a second side surface that are opposite to each other of the carrier circuit board. The electrical chip is disposed on the package circuit board, and the optical-electrical conversion module is separated from the package circuit board, to significantly reduce a size of the package circuit board, reduce processing difficulty and costs of the package circuit board, and reduce a loss of a high-speed signal transmission link. In addition, the carrier circuit board is provided with a first conductive via, and the package circuit board is electrically connected to the optical-electrical conversion module to reduce inter-board traces on a connection link between the optical-electrical conversion module and the package circuit board.

Abstract: A data retransmission method is provided herein. The method includes sending a data frame to an electronic device and receiving an acknowledgement frame from the electronic device within a transmission opportunity duration, where the acknowledgement frame includes first acknowledgement information; and when the first acknowledgement information indicates that at least a part of data in the data frame needs to be retransmitted and further indicates a retransmission period required to complete the retransmission, retransmitting information related to the at least the part of the data to the electronic device in the retransmission period.
