Detailed ways

The technical solutions in the embodiments of the present application will be clearly described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art fall within the protection scope of this application.

The terms "first", "second" and the like in the description and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It is to be understood that the data so used are interchangeable under appropriate circumstances so that the embodiments of the present application can be practiced in sequences other than those illustrated or described herein, and distinguish between "first", "second", etc. The objects are usually of one type, and the number of objects is not limited. For example, the first object may be one or more than one. In addition, "and/or" in the description and claims indicates at least one of the connected objects, and the character "/" generally indicates that the associated objects are in an "or" relationship.

The data transmission method and apparatus, electronic device, readable storage medium, and chip provided by the embodiments of the present application are described in detail below with reference to FIGS. 1 to 10 through specific embodiments and application scenarios thereof.

This embodiment provides a data transmission method, as shown in FIG. 1 , including:

Step S102: when the camera transmits data using the first interface protocol, determine whether the working mode of the communication antenna is a time division duplex mode;

Step S104 : when the working mode of the communication antenna is the time division duplex mode, adjust the working state of the camera in the transmission time slot of the communication antenna.

The data transmission method provided in this embodiment mainly adjusts the working state of the camera according to the working mode of the communication antenna when the camera needs to transmit data with the outside, so that the communication of the antenna can be interfered with the data of the camera. The transmission is staggered, so that the communication ability and the shooting transmission ability are greatly taken into account. Specifically, the data transmission protocol of the camera is first judged. In the case of the first interface protocol, the transmission rate is fast, but the anti-interference ability is weak. When the camera works with the first interface protocol, it will continuously Sending and receiving data to the outside, if the communication antenna also sends data during this process, it will have a negative effect on the data collection of the camera and affect the normal use. Similarly, the operation of the camera will also interfere with the communication effect of the communication antenna. . At this time, consideration of the communication parameters of the communication antenna will be introduced, mainly the working mode and the time slot state. According to the specific working mode and time slot state of the communication antenna, the working state of the camera can be adjusted in a targeted manner, thereby improving the anti-interference ability of the camera during data transmission. Power consumption is also greatly improved.

Among them, the time division duplex mode is the TDD mode, the transceiver shares a radio frequency point, and the uplink and downlink use different time slots for communication. Among them, for the uplink and downlink conversion period with a period of 5ms, the uplink and downlink ratios of the time slots of the TDD frame structure include: 3:2, 2:3, 1:4, 5:5, and for the uplink and downlink conversion period with a period of 10ms During the period, the uplink and downlink ratios of the time slots of the TDD frame structure include: 3:7, 2:8, and 1:9.

It can be understood that the first interface protocol is the C-PHY protocol, which has 9 lines. Compared with the 10 lines of the D-PHY protocol, the number of lines will be reduced. In a space with limited volume, such as a mobile phone will have great advantages. In addition, the power consumption of the C-PHY protocol is also less than that of the D-PHY protocol.

Those skilled in the art can understand that the C-PHY bus is 3Trio, that is, 9 lines, and the D-PHY bus is 4lane, that is, 10 lines. The transmission capacity of C-PHY is 1.71 times that of D-PHY, which is easier to meet high pixel The need for data transmission with high frame rate cameras. C-PHY adopts single-ended transmission line, D-PHY adopts differential transmission line, and C-PHY has weak anti-interference ability. C-PHY noise immunity is worse than D-PHY.

For example, for a camera with 40M or 48M pixels, the transmission bandwidth of D-PHY cannot be satisfied, and only the interface protocol of C-PHY can be used.

This application is precisely by staggering the camera MIPI C-PHY transmission and RF TX (transmission) time to maximize the user experience while ensuring the camera function.

Optionally, as shown in FIG. 2 , adjusting the working state of the camera in the sending time slot of the communication antenna includes:

Step S1042: Control the camera to stop working in the transmission time slot of the communication antenna.

When the communication antenna is in the sending time slot, in order to reduce the mutual interference between the camera and the communication antenna, the camera can be restricted to stop working, that is, the camera is not activated to take pictures or videos.

By using the characteristics of the frame time slot of TDD, the transmission of C-PHY can be staggered from the TX time slot of TDD when the camera is working, such as taking pictures or video, thereby reducing the interference to the data transmission of the camera.

In a specific embodiment, in the TDD system, if the data is sent within the time slot of the sending time slot, there will be mutual interference between the transmission of the camera and the communication of the antenna. At this time, the camera can be directly controlled when sending the time slot Stop transmission, that is, control the corresponding drive strength to 0, thereby reducing mutual interference and ensuring the communication quality of the antenna.

Optionally, as shown in FIG. 3 , adjusting the working state of the camera in the transmission time slot of the communication antenna includes:

Step S1044: Adjust the driving strength of the camera according to the radio frequency transmission power of the communication antenna in the transmission time slot of the communication antenna.

In another solution, when the communication antenna is in the sending time slot, in order to reduce the mutual interference between the camera and the communication antenna, the method of dynamically adjusting the driving strength of the camera is adopted to avoid it. Specifically, according to the actual power of the communication antenna, the data transmission of the camera is adjusted, that is, the corresponding driving strength is adjusted, so as to improve the anti-interference ability of the camera data transmission. The power level of the communication antenna can be adjusted flexibly, so as to save power consumption as much as possible.

It can be understood that the driving strength is the working power of the camera, and the adjustment of the driving strength is usually by adjusting the driving voltage of the source terminal. When the load is constant, it can be understood that the corresponding power P=U2/R increases, which is the working power of the camera. .

The driving capability of camera MIPI is generally controlled by AP. The driving capability of MIPI CLK/DATA at the AP side generally refers to adjusting the VOD voltage amplitude of the signal. There are two ways to adjust VOD. The first way is to adjust the VREG voltage. Piezoresistor.

Specifically, for the driving voltage of the communication antenna, the range from the minimum value min to the maximum value max can be divided into four gears, the first gear is a<P≤max, and the second gear is b<P≤ a, the third gear is c<P≤b, and the fourth gear is min<P≤c. When the power of the communication antenna is in the first gear, the driving strength of the camera can be controlled to be 0.54V; when the power of the communication antenna is in the second gear, the driving strength of the camera can be controlled to be 0.5V; When the power is in the third gear, the driving strength of the camera can be controlled to be 0.46V; when the power of the communication antenna is in the fourth gear, the driving strength of the camera can be controlled to be 0.42V.

Optionally, as shown in FIG. 4 , the camera includes a buffer, and the data transmission method further includes:

Step S106: storing the data information of the camera in the buffer in the transmission time slot of the communication antenna;

Step S108 : controlling the camera to transmit the data information in the buffer in the receiving time slot of the communication antenna.

A buffer can be added in the camera. Under the TDD system, the data information originally prepared to be sent out in the sending time slot will be temporarily stored in the buffer until it is the receiving time slot. The pre-stored data information in the device is transmitted, so as to avoid the interference between the transmission time slot and the antenna communication.

Optionally, when the camera transmits data using the first interface protocol, while adjusting the working state of the camera in the sending time slot of the communication antenna, the method further includes:

Reduce the shooting frame rate and/or shooting pixels of the camera; and/or increase the data transmission speed of the camera; and/or reduce the uplink ratio in the frame structure in the time division duplex mode.

On the basis of any of the above embodiments, in order to ensure the normal transmission of data, one of the following three methods can be selected, or a combination of multiple methods can be used at the same time: one is to reduce the camera pixel by reducing the camera frame rate. In other words, this method reduces the total data transmission amount during data transmission, so as to reduce the transmission time and ensure the basic video transmission; the second is to increase the transmission rate, reduce the transmission time, and ensure the normal transmission of data; the third is to further adjust the TDD frame structure based on the characteristics of the time slot of the TDD frame The UL:DL is changed from 2:3 to 1:4, reducing the number of TDD TX (transmission) frames, thereby increasing the MIPI transmission time and ensuring the normal transmission of data.

It should be understood that the chip mentioned in the embodiments of the present application may also be referred to as a system-on-chip, a system-on-chip, a system-on-a-chip, or a system-on-a-chip, or the like.

The present application also provides a specific data transmission method, as shown in FIG. 9 , including: step S202: starting the C-PHY camera; step S204: obtaining the terminal RF working standard; step S206: judging whether the current RF working standard is TDD If yes, go to step S208: obtain the terminal RF time slot status, otherwise go back to step S204; step S210: judge whether the time slot state is a TX time slot; if so, go to step S212: control the C-PHY to suspend transmission, Otherwise, go back to step S208.

When the user enables the MIPI CPHY camera, the terminal obtains the current working frequency band system. When it detects that the current working frequency band is the TDD standard, the 5G NR TDD standard frequency bands N78 and N41 are arranged near the camera. Using the TDD frame time slot feature, the MIPI CPHY transmission and the TDD TX (transmission) time slot are staggered in the photo or video scene, so as to avoid RF TX (transmission) radiation from interfering with MIPI CPHY transmission.

By adding a data buffer module in the camera module, when the RF is in the TX (transmit) time slot, data transmission is suspended, and when the RF is in the RX (receive) time slot, data transmission is resumed.

In a video call scenario:

①The total amount of data transmission can be reduced by further reducing the frame rate of the camera and reducing the pixels of the camera under the condition of ensuring the normal video call function.

②It can further improve the MIPI transmission rate, reduce the transmission time, and ensure the normal transmission of data.

③Based on the characteristics of TDD frame time slots, the TDD frame structure can be further adjusted by adjusting the uplink and downlink ratios, such as changing the uplink and downlink ratios from DL:UL from 3:2 to 4:1, reducing TDD TX (transmission) frames Quantity, thereby increasing the mipi transmission time and ensuring the normal data transmission is completed.

The present application also provides another specific data transmission method, as shown in FIG. 10 , including: step S302: starting the C-PHY camera; step S304: obtaining the terminal RF working standard; step S306: judging whether the current RF working standard is TDD standard; if yes, go to step S308: obtain the terminal RF time slot status, otherwise go back to step S304; step S310: judge whether the time slot state is a TX time slot; if so, go to step S312: obtain the terminal RF power, according to C-PHY mapping relationship between driving strength and power, adjust the driving strength of MIPI, otherwise return to step S308.

Combined with the characteristics of the TDD frame structure, considering that only the RF TX (transmission) scenario causes interference to MIPI CPHY, when the terminal detects that the RF is working in the TX (transmission) time slot, it can improve the anti-interference ability of MIPI CPHY by enhancing the driving strength of MIPI CPHY . When the terminal operates in the RX (receive) slot, MIPI CPHY restores the default drive strength. This method can save the power consumption of the whole machine to the greatest extent while solving the radio frequency interference MIPI CPHY.

In order to save the power consumption of the whole machine to the greatest extent, the terminal can find out the corresponding anti-RF power interference ability under different mipi driving strengths in advance, and establish a mapping table between different CPHY driving strengths and RF power. As shown in the table below:

MIPI CPHY drive strength RF power level 8mA a<P≤max 6mA b<P≤a 4mA c<P≤b 2mA min＜P≤c

When the RF works in the TX (transmit) time slot, the terminal looks up the table mapping table to adjust the CPHY drive strength to the corresponding gear according to the current RF power, thereby preventing RF TX (transmit) power radiation from interfering with MIPI CPHY transmission. When the RF works in the RX (receive) time slot, MIPI reduces the drive strength to the default state, thereby saving the power consumption of the whole machine.

The above two implementations can effectively solve the problem of camera function failure caused by the RF working scene interfering with MIPI CPHY data transmission. Using the TDD frame structure characteristics, the camera work stability is improved and the power consumption of the whole machine is saved to the maximum extent.
