Embodiment Construction

[0023] As mentioned in the background, in the prior art, when Wi-Fi shares a single antenna with other wireless technologies, there are deficiencies, which still need to be improved.

[0024] The inventors of the present application have found through research that in the prior art, when Wi-Fi shares a single antenna with other wireless technologies (for example, LTE technology), there are two schemes for stopping Wi-Fi transmission: Suspension mode and Abort mode. Both the suspend mode and the suspend mode are about to end when the Wi-Fi time slice is about to end, by issuing a command to Wi-Fi (for example, suspend command or suspend command) to stop Wi-Fi transmission, and can enter suspend mode or Abort mode.

[0025] Afterwards, the Wi-Fi may retransmit data by issuing a cancel suspend command or a cancel suspend command to the Wi-Fi. In the suspend mode and suspend mode, after the Wi-Fi transmission is stopped, the related status of the Wi-Fi transmission is also clear...

Abstract

A data transmission method and device, a storage medium, and a terminal of a multi-radio radio system, wherein the multi-radio system multiplexes the same radio frequency component to transmit Wi-Fi data and non-Wi-Fi data, and is used to transmit the Wi-Fi In the Wi-Fi time slice of the data, multiple data packets of Wi-Fi data are transmitted by allocating multiple TxOP periods, the method includes: when allocating the TxOP period, judging whether the TxOP period to be allocated exceeds the Wi-Fi period Fi time slice; if it exceeds, then adjust the TxOP cycle, so that the adjusted TxOP cycle does not exceed the Wi-Fi time slice. Through the technical solution of the invention, it is beneficial for multiple radio frequency systems to share a single antenna, so as to realize the coexistence of different radio frequency systems.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data transmission method and device, a storage medium, and a terminal of a multi-radio frequency system. Background technique [0002] In the current market, in order to reduce costs and save power consumption, the Wireless Fidelity (Wi-Fi) radio frequency system (Wi-Fi for short) and the Long Term Evolution (LTE) radio frequency system (LTE for short) on the same terminal LTE for short) usually share a single antenna to transmit Wi-Fi data and LTE data. When the shared single antenna is used, a Time Division Duplex (TDD for short, also known as Time Division Duplex) mechanism is generally used to allocate different time slices for Wi-Fi and LTE, so that Wi-Fi and LTE can operate on their respective Send and receive data within the time slice. [0003] In the TDD mechanism, the air interface time occupied by data packets transmitted by Wi-Fi may be very short o...
