  • Publication number: 20240397576
    Abstract: The application provides a wireless communication method and a wireless communication device. A part of payload is pre-fetched from a host to a data buffer under a store-and-forward mode before transmission begins. When data transmission begins, the part of the payload pre-fetched in the data buffer is transmitted to an antenna. A remaining part of the payload is fetched to the data buffer under a cut-through mode for payload transmission, wherein the remaining part of the payload is sent from the data buffer to the antenna for radiation.
