Data transmission method and device for multiple radio frequency systems, storage medium and terminal

A data transmission device for multiple radio frequency systems, wherein the multiple radio frequency systems multiplex a shared radio frequency component to transmit Wi-Fi data and non-Wi-Fi data, during a Wi-Fi time slice for transmitting the Wi-Fi data, a plurality of Transmission Opportunity Periods (TxOPs) are allocated to transmit a plurality of data packets of the Wi-Fi data, and the device comprises:

• a first determining circuitry configured to:
• during allocation of each of the plurality of TxOPs, determine whether the TxOP exceeds the Wi-Fi time slice;
• a first adjusting circuitry configured to:
• based on the TxOP exceeding the Wi-Fi time slice, adjust the TxOP to make the adjusted TxOP do not exceed the Wi-Fi time slice;
• a second determining circuitry configured to determine whether transmission of a current data packet can be completed within the adjusted TxOP;
• an allocating circuitry configured to:
• based on that the transmission of the current data packet can be completed within the adjusted TxOP, allocate the adjusted TxOP and transmit the current data packet, and based on that the transmission of the current data packet cannot be completed within the adjusted TxOP, not allocate the adjusted TxOP;
• and
• a first generating circuitry configured to:
• based on that the transmission of the current data packet can be completed within the adjusted TxOP, generate a non-zero CSMA backoff count value using a CSMA backoff counter after the adjusted TxOP expires.
