Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0037] The data transmission method, apparatus, passive device, electronic device and storage medium provided in the embodiments of the present application are described in detail below with reference to specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0038] The data transmission method may be applied to a terminal, and may be specifically executed by hardware or software in the terminal.

[0039] The terminal includes, but is not limited to, a portable communication device such as a mobile phone or tablet computer having a touch-sensitive surface (e.g., a touch screen display and / or a touch pad). It should also be understood that, in some embodiments, the terminal may not be a portable communication device, but a desktop computer having a touch-sensitive surface (e.g., a touch screen display and / or a touch pad).

[0040] In the following embodiments, a terminal including a display and a touch-sensitive surface is described. However, it should be understood that the terminal may include one or more other physical user interface devices such as a physical keyboard, a mouse, and a joystick.

[0041] The data transmission method provided in the embodiment of the present application can be executed by an electronic device or a functional module or functional entity in the electronic device that can implement the data transmission method. The electronic devices mentioned in the embodiment of the present application include but are not limited to mobile phones, tablets, computers, cameras and wearable devices. The data transmission method provided in the embodiment of the present application is described below using an electronic device as an example of the execution subject.

[0042] The present application provides a data transmission method, which is applied to a target passive device, wherein the target passive device is used to receive a first data packet sent by a target base station. In some embodiments, the data transmission method is applicable to a 3GPP standard Ambient IoT scenario.

[0043] like Figure 1 As shown, the data transmission method includes: step 110 and step 120.

[0044] Step 110: When the decoding operation on the first data packet fails, obtain a decoding failure count.

[0045] In actual implementation, the first data packet may be any data packet sent by the target base station to the target passive device. The target passive device may be any device that does not require energy from a second device and relies on itself to obtain energy from the surrounding environment.

[0046] In some embodiments, the target passive device may receive a first data packet sent by the target base station, and perform a decoding operation on the first data packet. If the decoding operation on the first data packet fails, a decoding failure count is obtained.

[0047] In some embodiments, the target passive device may request the target base station to send a next data packet if the decoding operation on the first data packet is successful.

[0048] In actual implementation, the decoding failure count may be a cumulative value of the number of times that the target passive device fails to perform a decoding operation on the current first data packet.

[0049] Step 120: When the decoding failure count is greater than or equal to the first threshold, send a data retransmission request to the target base station, so that the target base station retransmits the first data packet based on the data retransmission request.

[0050] In actual implementation, the first threshold may be a preset value. In some embodiments, the first threshold may be a value determined based on information about the current first data packet, such as the size of the first data packet, and the value may be positively correlated with the size of the first data packet. In some embodiments, the first threshold may be a value determined based on the energy state of the target passive device, and the value may be positively correlated with the energy state of the target passive device.

[0051] In some embodiments, the target passive device may determine a first threshold. For example, the target passive device determines the first threshold to be 5, and when the decoding failure count is 6, that is, the decoding failure count is greater than or equal to the first threshold, the target passive device sends a data retransmission request to the target base station, so that the target base station retransmits the first data packet based on the data retransmission request.

[0052] In some embodiments, the data retransmission request may be a negative-acknowledgment (NACK) feedback.

[0053] In some embodiments, the target passive device may decode the first data packet again if the decoding failure count is less than a first threshold.

[0054] In some embodiments, after receiving the data retransmission request sent by the target passive device, the target base station can obtain the number of retransmissions for the first data packet, and send the next data packet if the number of retransmissions is greater than the target number of retransmissions; correspondingly, if the number of retransmissions is less than the target number of retransmissions, the first data packet is retransmitted.

[0055] According to the data transmission method of an embodiment of the present application, when a decoding operation fails on a first data packet, a decoding failure count is obtained; when the decoding failure count is greater than or equal to a first threshold, a data retransmission request is sent to a target base station, so that the target base station retransmits the first data packet based on the data retransmission request; when the decoding failure count for decoding the first data packet is greater than or equal to the first threshold, the target base station is requested to retransmit the first data packet, thereby avoiding sending a retransmission request to the target base station for each decoding failure, resulting in frequent feedback operations, so as to reduce the energy consumption of the target passive device.

[0056] In some embodiments, when a decoding operation on the first data packet fails, before obtaining a decoding failure count, the target passive device may obtain backscatter signal strength; the backscatter signal strength represents the energy used by the target passive device for communication; and the first threshold is determined based on the backscatter signal strength.

[0057] In actual implementation, the backscatter signal strength (Received Signal Strength Indication, RSSI) may be an energy intensity value of information interaction between the target passive device and the surrounding environment at the current moment.

[0058] In some embodiments, the storage capacitor voltage and / or environmental harvested energy data of the target passive device may be obtained, and the backscattered signal strength may be obtained based on the storage capacitor voltage and / or environmental harvested energy data.

[0059] In some embodiments, the target passive device may determine the first threshold based on the magnitude of the backscatter signal strength.

[0060] According to the data transmission method of an embodiment of the present application, the target passive device obtains the backscatter signal strength and determines a first threshold based on the backscatter signal strength, so as to dynamically adjust the first threshold based on the energy state of the target passive device. This ensures the reliability of data transmission under different energy states and reduces the risk of link interruption. In the event that a decoding operation fails on the first data packet, a decoding failure count is obtained; if the decoding failure count is greater than or equal to the first threshold, a data retransmission request is sent to the target base station, so that the target base station retransmits the first data packet based on the data retransmission request. If the decoding failure count for decoding the first data packet is greater than or equal to the first threshold, the target base station is requested to retransmit the first data packet, thereby avoiding sending a retransmission request to the target base station for each decoding failure, which results in frequent feedback operations, thereby reducing the energy consumption of the target passive device.

[0061] In some embodiments, the first threshold can be determined to be a first value when the backscatter signal strength is greater than or equal to the target signal strength; when the backscatter signal strength is less than the target signal strength, the first threshold can be determined to be a second value; the second value is less than the first value.

[0062] In actual implementation, the first value and the second value may be any theoretically feasible values. For example, the first value and the second value may be positive integers, and the second value may be smaller than the first value.

[0063] In actual implementation, the target signal strength may be a preset strength value.

[0064] In some embodiments, the target passive device may obtain backscattered signal strength, and when the backscattered signal strength is greater than or equal to the target signal strength, the first threshold is determined to be a first value. For example, if the backscattered signal strength value obtained by the target passive device is 600, and the target signal strength is 500, that is, the backscattered signal strength is greater than or equal to the target signal strength, the first threshold is determined to be the first value, for example, 5. If the backscattered signal strength value obtained by the target passive device is 200, and the target signal strength is 500, that is, the backscattered signal strength is less than or equal to the target signal strength, the first threshold is determined to be a second value, for example, 3.

[0065] According to the data transmission method of an embodiment of the present application, the target passive device obtains the backscatter signal strength and determines a first threshold based on the backscatter signal strength, so as to dynamically adjust the first threshold based on the energy state of the target passive device. This ensures the reliability of data transmission under different energy states and reduces the risk of link interruption. In the event that a decoding operation fails on the first data packet, a decoding failure count is obtained; if the decoding failure count is greater than or equal to the first threshold, a data retransmission request is sent to the target base station, so that the target base station retransmits the first data packet based on the data retransmission request. If the decoding failure count for decoding the first data packet is greater than or equal to the first threshold, the target base station is requested to retransmit the first data packet, thereby avoiding sending a retransmission request to the target base station for each decoding failure, which results in frequent feedback operations, thereby reducing the energy consumption of the target passive device.

[0066] In some embodiments, if the decoding operation on the first data packet fails, the decoding failure count is increased by one.

[0067] In actual implementation, when determining that the decoding operation is performed on the first data packet for the first time, the target passive device determines the decoding failure count to be 0 and performs the decoding operation on the first data packet.

[0068] In some embodiments, when the decoding operation on the first data packet fails, the decoding failure count is increased by one. For example, if the original decoding failure count is 2, when the decoding operation on the first data packet fails, the decoding failure count is determined to be 3.

[0069] According to the data transmission method of an embodiment of the present application, when a decoding operation fails on a first data packet, a decoding failure count is obtained; when the decoding failure count is greater than or equal to a first threshold, a data retransmission request is sent to a target base station, so that the target base station retransmits the first data packet based on the data retransmission request; when the decoding failure count for decoding the first data packet is greater than or equal to the first threshold, the target base station is requested to retransmit the first data packet, thereby avoiding sending a retransmission request to the target base station for each decoding failure, resulting in frequent feedback operations, so as to reduce the energy consumption of the target passive device.

[0070] In some embodiments, a decoding operation may be performed on the first data packet; if the decoding operation is successful, data successful reception information is sent to the target base station, so that the target base station sends the next data packet.

[0071] In some embodiments, the target device may decode the first data packet based on any theoretically feasible decoding technology. For example, the target passive device may decode the first data packet based on channel coding technology, real-time transport protocol, or any other theoretically feasible decoding technology.

[0072] In actual implementation, the data successful reception information may include an acknowledgment character (ACK) for indicating to the target base station that the first data packet has been successfully received.

[0073] In some embodiments, the target passive device may send data successful reception information to the target base station if the decoding operation is successful, so that the target base station sends the next data packet, for example, the target base station sends the second data packet.

[0074] According to the data transmission method of an embodiment of the present application, when a decoding operation fails on a first data packet, a decoding failure count is obtained; when the decoding failure count is greater than or equal to a first threshold, a data retransmission request is sent to a target base station, so that the target base station retransmits the first data packet based on the data retransmission request; when the decoding failure count for decoding the first data packet is greater than or equal to the first threshold, the target base station is requested to retransmit the first data packet, thereby avoiding sending a retransmission request to the target base station for each decoding failure, resulting in frequent feedback operations, so as to reduce the energy consumption of the target passive device.

[0075] In order to better understand the data transmission method provided in the embodiments of the present application, further explanation is given below. It should be understood that the discussion below is only exemplary.

[0076] This application provides a data transmission method, the specific steps can be as follows Figure 2 As shown:

[0077] Step 210: Decode the first data packet; if the decoding operation is successful, send data successful reception information to the target base station so that the target base station sends the next data packet.

[0078] In some embodiments, the target device may decode the first data packet based on any theoretically feasible decoding technology. For example, the target passive device may decode the first data packet based on channel coding technology, real-time transport protocol, or any other theoretically feasible decoding technology.

[0079] In actual implementation, the data successful reception information may include an acknowledgment character (ACK) for indicating to the target base station that the first data packet has been successfully received.

[0080] In some embodiments, the target passive device may send data successful reception information to the target base station if the decoding operation is successful, so that the target base station sends the next data packet, for example, the target base station sends the second data packet.

[0081] Step 220: The target passive device may obtain backscatter signal strength; the backscatter signal strength represents the energy used by the target passive device for communication.

[0082] In actual implementation, the backscatter signal strength may be an energy intensity value of information interaction between the target passive device and the surrounding environment at the current moment.

[0083] In some embodiments, the storage capacitor voltage and / or environmental harvested energy data of the target passive device may be obtained, and the backscattered signal strength may be obtained based on the storage capacitor voltage and / or environmental harvested energy data.

[0084] In some embodiments, the target passive device may determine the first threshold based on the magnitude of the backscatter signal strength.

[0085] Step 230: When the backscatter signal strength is greater than or equal to the target signal strength, determine the first threshold to be a first value; when the backscatter signal strength is less than the target signal strength, determine the first threshold to be a second value; the second value is less than the first value.

[0086] In actual implementation, the first value and the second value may be any theoretically feasible values. For example, the first value and the second value may be positive integers, and the second value may be smaller than the first value.

[0087] In actual implementation, the target signal strength may be a preset strength value.

[0088] In some embodiments, the target passive device may obtain backscattered signal strength, and when the backscattered signal strength is greater than or equal to the target signal strength, the first threshold is determined to be a first value. For example, if the backscattered signal strength value obtained by the target passive device is 600, and the target signal strength is 500, that is, the backscattered signal strength is greater than or equal to the target signal strength, the first threshold is determined to be the first value, for example, 5. If the backscattered signal strength value obtained by the target passive device is 200, and the target signal strength is 500, that is, the backscattered signal strength is less than or equal to the target signal strength, the first threshold is determined to be a second value, for example, 3.

[0089] Step 240: When the decoding operation on the first data packet fails, obtain a decoding failure count.

[0090] In actual implementation, the first data packet may be any data packet sent by the target base station to the target passive device. The target passive device may be any device that does not require energy from a second device and relies on itself to obtain energy from the surrounding environment.

[0091] In some embodiments, the target passive device may receive a first data packet sent by the target base station, and perform a decoding operation on the first data packet. If the decoding operation on the first data packet fails, a decoding failure count is obtained.

[0092] In some embodiments, the target passive device may request the target base station to send a next data packet if the decoding operation on the first data packet is successful.

[0093] In actual implementation, the decoding failure count may be a cumulative value of the number of times that the target passive device fails to perform a decoding operation on the current first data packet.

[0094] In some embodiments, if the decoding operation on the first data packet fails, the decoding failure count is increased by one.

[0095] In actual implementation, when determining that the decoding operation is performed on the first data packet for the first time, the target passive device determines the decoding failure count to be 0 and performs the decoding operation on the first data packet.

[0096] In some embodiments, when the decoding operation on the first data packet fails, the decoding failure count is increased by one. For example, if the original decoding failure count is 2, when the decoding operation on the first data packet fails, the decoding failure count is determined to be 3.

[0097] Step 250: When the decoding failure count is greater than or equal to the first threshold, send a data retransmission request to the target base station, so that the target base station retransmits the first data packet based on the data retransmission request.

[0098] In some embodiments, as Figure 3 As shown, the target passive device may determine whether the decoding failure count is greater than or equal to a first threshold.

[0099] In actual implementation, the first threshold may be a preset value. In some embodiments, the first threshold may be a value determined based on information about the current first data packet, such as the size of the first data packet, and the value may be positively correlated with the size of the first data packet. In some embodiments, the first threshold may be a value determined based on the energy state of the target passive device, and the value may be positively correlated with the energy state of the target passive device.

[0100] In some embodiments, the target passive device may determine a first threshold. For example, the target passive device determines the first threshold to be 5, and when the decoding failure count is 6, that is, the decoding failure count is greater than or equal to the first threshold, the target passive device sends a data retransmission request to the target base station, so that the target base station retransmits the first data packet based on the data retransmission request.

[0101] In some embodiments, the data retransmission request may be a negative-acknowledgment (NACK) feedback.

[0102] In some embodiments, the target passive device may decode the first data packet again if the decoding failure count is less than a first threshold.

[0103] In some embodiments, after receiving the data retransmission request sent by the target passive device, the target base station can obtain the number of retransmissions for the first data packet, and send the next data packet if the number of retransmissions is greater than the target number of retransmissions; correspondingly, if the number of retransmissions is less than the target number of retransmissions, the first data packet is retransmitted.

[0104] According to the data transmission method of the embodiment of the present application, a single ACK feedback mechanism that feeds back an ACK to the target base station only when the decoding operation of the first data packet is successful reduces the line signaling overhead of the target passive device, reduces the energy consumption of the target passive device, and extends the service life of the device. In the case of a failure in decoding the first data packet, a decoding failure count is obtained; when the decoding failure count is greater than or equal to a first threshold, a data retransmission request is sent to the target base station, so that the target base station retransmits the first data packet based on the data retransmission request. When the decoding failure count of decoding the first data packet is greater than or equal to the first threshold, the target base station is requested to retransmit the first data packet, thereby avoiding sending a retransmission request to the target base station every time a decoding failure occurs, resulting in frequent feedback operations, thereby reducing the energy consumption of the target passive device and being more in line with the performance characteristics of the passive device.

[0109] According to the data transmission device of an embodiment of the present application, when a decoding operation fails on a first data packet, a decoding failure count is obtained; when the decoding failure count is greater than or equal to a first threshold, a data retransmission request is sent to a target base station, so that the target base station retransmits the first data packet based on the data retransmission request; when the decoding failure count for decoding the first data packet is greater than or equal to the first threshold, the target base station is requested to retransmit the first data packet, thereby avoiding sending a retransmission request to the target base station for each decoding failure, resulting in frequent feedback operations, so as to reduce the energy consumption of the target passive device.
