DETAILED DESCRIPTION

The technical solutions in embodiments of the present disclosure will be clearly and completely described in the following with reference to the accompanying drawings in the embodiments.

The technical solutions of embodiments of the present disclosure can be applied to short-range wireless communication. When the sending end device approaches the antenna of the receiving end device, the non-contact point-to-point data transmission and communication between the sending end device and the receiving end device can be realized. Meanwhile, high speed data wireless transmission can be realized based on a high carrier frequency (e.g., 60 GHz).

The short-range wireless communication method will be illustrated inFIG. 1.

As illustrated inFIG. 1, the short-range wireless communication system100includes the sending end device110and the receiving end device120. The sending end device110and the receiving end device120can realize non-contact high-speed data transmission. In some embodiments, an extremely high frequency (EHF) antenna is packaged in an integrated circuit (IC) chip of the sending end device110, and thus, the sending end device110can implement high-speed wireless data transmission (e.g., a transmission speed up to 6 GB/s) based on a high carrier frequency (e.g., 60 GHz). In some embodiments, the EHF antenna can also be packaged in the IC chip of the receiving end device120, so that two-way communication between the sending end device110and the receiving end device120can be implemented. In some embodiments, wireless data transmission between the sending end device110and the receiving end device120can be realized by using electromagnetic signals.

It should be understood that the short-range wireless communication based on high carrier frequency has advantages of low power consumption, small size, fast transmission rate, and non-contact transmission, and can also realize the function of the plug-and-play module, which can greatly improve the signal integrity and support implementations of more flexible system, reduce standby power consumption, increase bandwidth amplitude and improve the data transmission security, and can also be compatible with supporting high-speed video signal.

At present, in the short-range wireless communication based on high carrier frequency, the communication connection between the sending end device and the receiving end device may be interrupted at any time due to accident or artificial reasons, thereby interrupting the file data being transmitted, and the file data needs to be retransmitted after connection is restored, which not only wastes resources but also affects the user experience.

In order to solve the above technical problem, embodiments of the present disclosure provide a data transmission method, which can realize the breakpoint continuous transmission between the sending end device and the receiving end device in the short-distance wireless communication based on high carrier frequency.

The technical solutions in the present disclosure will be illustrated in the accompanying drawings.

FIG. 2is a schematic flowchart of a data transmission method200according to embodiments of the present disclosure. The method200is applied to the short-range wireless communication system100illustrated inFIG. 1, in the process of the sending end device sending data to be transmitted to the receiving end device. The method200includes at least some of the followings.

At block S210, after short-range wireless communication interrupted between the sending end device and the receiving end device is restored, the sending end device queries recorded transmission information, in which the transmission information is used to indicate a data block, transmission of which is not completed, in the data to be transmitted.

It should be understood that, the high carrier frequency may be a carrier frequency capable of realizing high speed wireless data transmission. The high carrier frequency may be an explicit carrier frequency, or may be a carrier frequency band, for example, 30 GHz to 300 GHz, which is not specifically limited in embodiments of the present disclosure.

Preferably, the high carrier frequency is 60 GHz.

In some embodiments, the sending end device includes an IC chip internally packaged with an EHF antenna.

For example, the sending end device includes an independent transmission chip. For example, the independent transmission chip is the IC chip internally packaged with the EHF antenna. The transmission power of the independent transmission chip may be a high frequency of 60 GHz, thereby realizing the high-speed (e.g., 6 GB/s) data transmission between the sending end device and the receiving end device.

In detail, the sending end device queries the recorded transmission information according to the recording table, in which the recording table includes a data block, transmission of which is not completed, in the data to be transmitted and/or a data block that has been completely transmitted in the data to be transmitted.

For example, the sending end device can query the recording table with respect to the receiving end device, or the sending end device can query the recording table corresponding to the identifier of the receiving end device. In this case, the recording table records only the transmission information that the sending end device sends the data to be transmitted to the receiving end device, such that the transmission information recorded can be queried.

For another example, the sending end device can query all the recording tables currently saved, further determine the recording table of the receiving end device, and query the transmission information recorded in the recording table.

It should be understood that, in the process of transmitting the data to be transmitted, the sending end device establishes the recording table corresponding to the identifier of the receiving end device. Every time the sending end device completes sending one data block to the receiving end device, the recording table records that the transmission of the corresponding data block is completed. Therefore, the transmission information can timely reflect the transmission circumstances of the data blocks in the data to be transmitted.

In some embodiments, when the data to be transmitted includes at least one data block, transmission of which is not completed, the sending end device saves the recording table. When the transmission of all the data blocks in the data to be transmitted are completed, the sending end device stops saving the recording table. Therefore, the overhead caused by saving the recording table can be reduced.

It should be understood that the transmission information recorded in the recording table may be the transmission information corresponding to the indexes of the data blocks, or may be the transmission information corresponding to the identifiers of the data blocks, or may be the transmission information corresponding to the numbers of the data blocks, which is not limited in the embodiments of the present disclosure.

For example, in the recording table illustrated in Table 1, the sending end device divides the data to be transmitted into 7 data blocks, the indexes 1-7 respectively being corresponding to 7 data blocks. After the sending end device transmits the data block 1, the data block 2, and the data block 3, the short-range wireless communication connection between the sending end device and the receiving end device is interrupted due to the positional offset or the artificial movement, the transmission of the data to be transmitted is interrupted, and the sending end device saves the recording table. After the short-range wireless communication connection between the sending end device and the receiving end device is restored, the sending end device queries the recording table, thereby determining that the data block 4, the data block 5, the data block 6, and the data block 7 need to be continuously transmitted.

For another example, in the recording table illustrated in Table 2, the sending end device divides the data to be transmitted into 7 data blocks, and the indexes 1-7 being corresponding to 7 data blocks respectively, and the sending end device discards the recording table after transmitting all 7 data blocks.

It should be noted that when the sending end device sends the data to be transmitted to the receiving end device, the sending end device or the receiving end device disconnects the short-range wireless communication connection between the sending end device and the receiving end device due to the positional offset or the artificial cause, and thus the sending end device interrupts the transmission of the data to be transmitted.

Preferably, the data to be transmitted is big data, for example, the number of bits occupied by the transmission data is greater than 20 GB.

In some embodiments, after the short-range wireless communication connection between the sending end device and the receiving end device is established, the sending end device and the receiving end device send the respective unique device identifier to each other, and respectively save the unique device identifier of the opposite end.

Alternatively, the unique identifier may be a media access control (MAC) address, or a combination of the MAC address plus a filed such as a device name, or the like.

It should be noted that, in embodiments of the present disclosure, after determining the data to be transmitted, the sending end device may divide the data to be transmitted into several data blocks. For example, the sending end device may divide the data to be transmitted into several data blocks according to the transmission rate of the sending end device and the transmission rate of the receiving end device, and the transmission duration of each data block is less than or equal to the preset duration. For example, the preset duration may be 1 s. For example, if the wireless transmission rate of the sending end device and/or the receiving end device is 6 G bits per second, then each data block should be less than or equal to 6 G bits.

For example, the sending end device can determine its own transmission rate based on the characteristics of the transmission chip and the wireless communication protocol employed. The sending end device can determine the transmission rate of the receiving end device based on the adopted wireless communication protocol.

It should be understood that the sending end device can divide the data to be transmitted into a plurality of data blocks evenly, and can also randomly divide the data to be transmitted into a plurality of data blocks, which is not limited in the embodiments of the present disclosure.

In some embodiments, before the sending end device queries the recorded transmission information, the sending end device determines that there is data to be transmitted, transmission of which is interrupted, between the sending end device and the receiving end device.

In some embodiments, the sending end device may determine whether there is transmission information corresponding to the identifier of the receiving end device, thus determining whether there is data to be transmitted, transmission of which is interrupted, between the sending end device and the receiving end device.

For example, if the sending end device determines that there is transmission information corresponding to the identifier of the receiving end device, the sending end device determines that there is data to be transmitted, transmission of which is interrupted, between the sending end device and the receiving end device. If the sending end device determines that there is no transmission information corresponding to the identifier of the receiving end device, the sending end device determines that there is no data to be transmitted, transmission of which is interrupted, between the sending end device and the receiving end device.

In some embodiments, the sending end device may also directly determine whether there is data to be transmitted, transmission of which is interrupted, between the sending end device and the receiving end device. For example, the sending end device receives the feedback message fed back by the receiving end device indicating that the receiving end device fails to receive the data to be transmitted, and the sending end device determines that there is data to be transmitted, transmission of which is interrupted, between the receiving end device and the sending end device. For another example, when the sending end device fails to send the data to be transmitted, the sending end device may generate indication information indicating that the data to be transmitted is not successfully transmitted, so that the sending end device may determine, according to the indication information, that there is data to be transmitted, transmission of which is interrupted, between the sending end device and the receiving end device.

At block S220, the sending end device sends the data block, transmission of which is not completed, in the data to be transmitted to the receiving end device.

It should be noted that the receiving end device may save the data block a received before the short-range wireless communication is interrupted, and after the short-range wireless communication is restored, the receiving end device receives the data block b, in this case, the receiving end device can merge the data block a with the data block b, to obtain the complete data to be transmitted.

It should also be noted that after the short-range wireless communication that is interrupted between the sending end device and the receiving end device is restored, the risk of being interrupted may also be faced. Therefore, after the short-range wireless communication is restored, the sending end device also needs to update the recording table in real time, that is, every time the sending end device completes sending one data block to the receiving end device, the recording table records that the transmission of the corresponding data block is completed.

In some embodiments, the sending end device is a wireless charging base, and the sending end device wirelessly charges the receiving end device in the process of performing short-range wireless communication between the sending end device and the receiving end device.

It should be understood that the wireless charging is mainly implemented by magnetic coupling (or electromagnetic induction), magnetic resonance or radio waves. Currently, mainstream wireless charging standards include the QI standard, the power matters alliance (PMA) standard, and the alliance for wireless power (A4WP) standard. Both the QI standard and the PMA standard adopt magnetic coupling for wireless charging. The A4WP standard adopts magnetic resonance for wireless charging.

In some embodiments, as illustrated inFIG. 3, the wireless charging base210establishes short-range wireless communication with the receiving end device220, and meanwhile the wireless charging base210wirelessly charges the receiving end device220. After the interrupted short-range wireless communication between the wireless charging base210and the receiving end device220is restored, breakpoint continuous transmission can be realized between the wireless charging base210and the receiving end device220, and the electronic device230can provide data for the wireless charging base210. The receiving end device220may be a device having a wireless charging and wireless transmission function, such as a mobile phone and a tablet, and the electronic device230may be a device having data processing and transmission function, such as a computer.

In some embodiments, as illustrated inFIG. 3, the electronic device230can also serve as a power supply device of the wireless charging base210, and can simultaneously provide power and data to the wireless charging base210via the external interface a.

In some embodiments, as illustrated inFIG. 3, an adapter240can serve as a power supply device for the wireless charging base210, and can provide power to the wireless charging base210via the external interface b.

It should be understood that the external interface a and the external interface b may be the same interface or different interfaces.

In detail, as illustrated inFIG. 3, the power supply device is coupled to the wireless charging base210via the external interface, and the wireless charging base210converts the output current of the power supply device into an electromagnetic signal (or electromagnetic wave) through the internal wireless transmitting circuit211for transmission. For example, the wireless transmitting circuit211can convert an output current of the power supply device into an alternating current, and convert the alternating current into the electromagnetic signal through a transmitting coil or a transmitting antenna (not shown). The receiving end device220can receive the electromagnetic signal transmitted by the wireless transmitting circuit211through the wireless receiving circuit221and convert the electromagnetic signal into an output current of the wireless receiving circuit221. For example, the wireless receiving circuit221can convert the electromagnetic signal transmitted by the wireless transmitting circuit211into an alternating current through a receiving coil or a receiving antenna (not shown), and perform operations such as rectification and/or filtering on the alternating current to convert the alternating current into an output voltage and an output current of the wireless receiving circuit221. The output voltage and the output current of the wireless receiving circuit221can be used to charge the receiving end device220(the battery of the receiving end device220).

Meanwhile, the electronic device230can transmit the data to be transmitted to the wireless charging base210through the external interface a, and the first communication control unit213in the wireless charging base210controls the first wireless transmission chip212to transmit the data to be transmitted to the receiving end device220, and the receiving end device220can control the second wireless transmission chip222to receive data to be transmitted through the second communication control unit223. The first communication control unit213may include, for example, a micro control unit (MCU) that can generally control the wireless charging process, the wireless data transmission process, and the communication process of the wireless charging base210. The second communication control unit223may be, for example, a central processing unit (CPU) that can generally control the wireless charging process, the wireless data transmission process, and the communication process of the receiving end device220. The first transmission chip212and the second transmission chip222may be, for example, an IC chip in which an EHF antenna is internally packaged, and its transmission power may be a high frequency of 60 GHz.

It should be noted that, as illustrated inFIG. 3, after the short-range wireless communication that is interrupted between the wireless charging base210and the receiving end device220is restored, the wireless charging base210can query the recorded transmission information through the first communication control unit213, and transmit data blocks, transmission of which is not completed, in the data to be transmitted to the receiving end device220.

It should be understood that the wireless charging base210may include a read only memory and/or a random access memory having a specific storage function, so that the transmission information can be recorded.

In the embodiment illustrated inFIG. 3, the receiving end device220can also control the second wireless transmission chip222to transmit data to the wireless charging base210through the second communication control unit223. In other words, short-range wireless communication between the wireless charging base210and the receiving end device220can be two-way communication.

Therefore, in the data transmission method of the embodiments of the present disclosure, after the short-range wireless communication that is interrupted between the sending end device and the receiving end device is restored, the sending end device queries the recorded transmission information and continuous sending the data block, transmission of which is not completed, in the data to be transmitted, such that breakpoint continuous transmission can be realized between the sending end device and the receiving end device.
