As shown in fig. 2, the embodiment of the present application provides a signal transmission method, which can be applied to the electronic device 100 shown in fig. 1, and the electronic device can include an Application (AP) processor, a radio frequency chip, and other chips. The method comprises the following steps:

s201: the application processor controls the radio frequency chip to transmit the radio frequency signal in a first time slot in a first wireless frame.

Illustratively, the electronic device may further include a baseband processing chip. Alternatively, it can be described that the other chips described above further include a baseband processing chip. In the above S201, the application processing chip may specifically send a radio frequency control signal to the baseband processing chip, and after receiving the radio frequency control signal, the baseband processing chip may control the radio frequency chip to transmit a radio frequency signal in a first time slot of a first radio frame.

S202: and the application processor controls any two components including the application processor and other chips to transmit internal signals in a second time slot in the first wireless frame, wherein the first time slot and the second time slot are not overlapped. The internal signals include data signals and/or control signals and the like transmitted between any two components. In a specific application, the rf chip may be a chip for wireless communication, such as a chip for 2G communication. The other chips may include one or more of peripheral chips of the electronic device (for example, chips corresponding to peripherals such as a camera and a display screen of the electronic device), a WIFI radio frequency chip, a bluetooth radio frequency chip, and the like, without limitation.

For example, as shown in fig. 3, in a Time Division Multiple Access (TDMA) system, each time slot (time) is 577us, each radio frame includes 8 time slots, and each radio frame duration 577us × 8 is 4.616 ms. The first 577us of each radio frame may be used for transmission of radio frequency signals and the last 4.039ms of each radio frame may be used for transmission of internal signals. Alternatively, it can be described as: each wireless frame comprises 8 time slots which are sequenced according to the time sequence, namely the time slot 0 to the time slot 7, wherein the time slot 0 is used for transmitting radio frequency signals, and the time slot 1 to the time slot 7 are used for transmitting internal signals. Here, the time slot 0 may correspond to the first time slot in the process of fig. 2, and the time slots 1 to 7 may correspond to the second time slot in the process of fig. 2.

For the flow shown in fig. 2, a specific embodiment is provided: and carrying out hardware test on the internal data line of the electronic equipment, and finding out an interfered source interfered by the radio frequency signal. The maximum transmission power level of the radio frequency signal which can normally work by the interfered source is confirmed through debugging and testing, and the maximum transmission power level of the radio frequency signal can be used as a starting threshold of an interference isolation program, wherein the starting threshold of the interference isolation program can also be called a preset threshold. When the transmission power level of the radio frequency signal exceeds the set maximum transmission power level, the method shown in the flow of fig. 2 is performed, i.e., the steps of S201 and S202 are performed. Otherwise, the radio frequency signal and the internal signal inside the electronic device are transmitted according to the existing mode.

As can be seen from the above description, the duration of the second time slot in the first radio frame is limited. For example, in the example of fig. 3 described above, the duration of the second slot is 4.039 ms. Therefore, in the embodiment of the present application, the application processor needs to calculate whether the internal signal to be currently transmitted needs to be transmitted in multiple times. Alternatively, it can be described as: the application processor needs to calculate whether the current internal signal to be transmitted can be completely transmitted in a second time slot (for example, 4.039ms) of one wireless frame, and if the current internal signal to be transmitted cannot be completely transmitted in the second time slot of one wireless frame, the current internal signal to be transmitted needs to be carried in the second time slot of different wireless frames for transmission for multiple times. For example, the application processor may split the data to be currently transmitted into N data blocks, and the application processor transmits the N data blocks in N second time slots respectively corresponding to N radio frames including the first radio frame. The specific treatment process can be as follows:

the application processor acquires the data volume and the transmission rate of the signal to be transmitted between any two components; the application processor determines a first time length required by the transmission of the signal according to the data volume and the transmission rate of the signal to be transmitted; for example, the first time length is the data amount/transmission rate of the signal to be transmitted; if the duration corresponding to the second time slot in the first wireless frame is greater than or equal to the first time slot, it may be considered that the transmission of the current signal may be completed in the first wireless frame, and it is sufficient to directly transmit the current signal to be transmitted in the second time slot in the first wireless frame. For example, still following the example of fig. 3, it can be seen that the duration of the second time slot is 4.039ms, and if the first duration for transmitting the signal is less than or equal to 4.039ms, the internal signal to be transmitted may be directly transmitted in the first radio frame. Setting the components for data transmission between any two components as a first component and a second component, and if the first time length for transmitting the internal signals is more than 4.039ms, controlling the first component to cut the internal signals to be transmitted into N data blocks by the application processor. And the application processor controls the first component to sequentially transmit N data blocks to the second component in N second time slots respectively corresponding to N wireless frames including the first wireless frame. Optionally, the application processor may allocate identifiers for the N data blocks respectively; the application processor may further control the first component to sequentially transmit the N data blocks to the second component in N second time slots corresponding to the N radio frames, respectively, according to the identification sequence. Further, the application processor may check the N data blocks according to the identification order. For example, the application processor may control the second component to splice the received N data blocks in the identified order to form spliced data. The application processor checks the spliced data. For example, the application processor may determine whether the data volume of the concatenated data and the data volume of the original data are the same, and if so, the verification may be considered successful; otherwise, the check is deemed to have failed. Finally, if the check fails, the application processor controls the first component to retransmit the original data, or may be described as the application processor controlling the first component to re-perform the above-described operation of dividing the internal signal into a plurality of data blocks.

As can be seen from the above description, in the embodiment of the present application, the transmission of the high-power transmission signal and the internal signal in the electronic device can be isolated, so as to avoid the interference of the high-power transmission signal on the internal data transmission of the electronic device.

The peripheral B can be a liquid crystal display screen of the electronic equipment, and the peripheral B chip can be a chip inside the liquid crystal display screen and the like.

The AP processor can send radio frequency control signaling to the baseband processing chip, and the baseband processing chip can respectively send synchronous signals to the radio frequency chip and the AP processor when receiving the radio frequency control command. After receiving the synchronization signal, the radio frequency chip periodically transmits a radio frequency signal in the first 577us of each radio frame according to a preset mode. After receiving the synchronization signal, the AP processor controls any two chips including the "AP processor, the chip of the peripheral a, and the chip of the peripheral B" to transmit an internal signal in the last 4.039ms of each wireless frame, where the internal signal may be an internal data signal between any two components, or an internal control signal, and the like, and is not limited. It should be noted that, in the example shown in fig. 4, the peripheral a chip transmits a data signal to the AP processor, and the AP processor transmits a data signal to the peripheral B chip. Data transmission between the peripheral A chip and the AP processor and data transmission between the AP processor and the peripheral B chip can be performed in parallel within the last 4.039ms of each wireless frame, or time-sharing transmission and the like, without limitation.

Optionally, the baseband processing chip may send information such as radio frequency power level to the AP processor, in addition to sending the synchronization signal to the AP processor. After receiving the radio frequency power level, the AP processor can compare the radio frequency power level with a starting threshold of an isolation interference program; and if the radio frequency power level is greater than or equal to the starting threshold, the process of sending the radio frequency signal in the first 577us of each radio frame and transmitting the internal signal in the last 4.039ms of each radio frame is started again. Otherwise, according to the existing method, the radio frequency signal and the internal signal of the electronic device are transmitted.

It should be noted that, in the example shown in fig. 4, it is described as an example that the baseband processing chip transmits the synchronization signal to the AP processor, and then the AP processor controls to transmit the internal signal between any two elements within the last 4.039ms of each radio frame. In an embodiment, the baseband processing chip may directly send the synchronization signal to a signal sending end inside the electronic device, for example, a peripheral a chip, and then the signal sending end of the electronic device directly transmits the internal signal in the second time slot of each wireless frame.

The application processor may partition the data into N data blocks and add an identification to each data block: an. Each data block is transmitted sequentially within the radio frequency gap. And n-1 is performed for each data transmission until the transmission is finished when n-0.
