Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0161] A-IoT is a new IoT technology. Compared to traditional IoT technologies, a notable feature is the massive number of A-IoT terminals (A-IoT UEs, also known as A-IoT devices or A-IoT tags) in the network, enabling large-scale inventory and monitoring of items. To further conserve power and reduce device complexity, a key feature of new A-IoT devices is the ability to harvest energy from the environment for communication. A-IoT devices have broad application prospects, including equipment identification and sensors for warehouse storage, eliminating the cost of battery configuration and replacement.

[0162] Compared to NB-IoT terminals, A-IoT terminals have a simpler structure and lower hardware and maintenance costs. The entire device can be equipped with or without a power supply. In current discussions, A-IoT devices can be categorized into three types: Type A, Type B, and Type C. Type A devices do not support energy storage or only support a small amount of energy storage. They primarily operate based on backscatter, exhibiting the lowest complexity and consuming very little power. For example, Type A devices need to receive wireless signals to generate energy to activate their internal receive processing modules. Type B devices support energy storage and operate based on backscatter. Their complexity and power consumption are higher than those of Type A devices, but still relatively low. The energy storage capacity of Type B devices is still relatively limited. Type C devices support energy storage and operate based on active transmission. That is, Type C devices can amplify and transmit information through power amplifiers. Type C devices generally require more energy storage to support active transmission.

[0163] To reduce the complexity of A-IoT devices, they typically only support simple transmission and reception operations. A-IoT devices may not support Radio Resource Management (RRM) measurements such as Reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ), or Received Signal Strength Indication (RSSI). The solution primarily addresses the problem of determining the channel status of an A-IoT device in the network and selecting the appropriate device to communicate with it.

[0164] In response to the above problems, the present disclosure proposes a communication method based on the environmental Internet of Things. This method can determine whether the uplink information of the A-IoT device is correctly received by receiving the uplink signal transmitted by the A-IoT device based on backscattering, and can measure the uplink signal transmitted by the A-IoT device and determine the device suitable for communicating with the A-IoT device based on the measurement value.

[0165] To implement the above method and support data transmission between A-IoT devices, the communication system needs to support the following functions. A device in the communication system can support one or more of the following functions.

[0166] 1. As an excitation signal, this is typically a continuous wave (CW) function, used only by Devices A and B. A-IoT devices can achieve uplink transmission via backscatter CW. In the embodiments of this disclosure, continuous wave and excitation have the same meaning and can be used interchangeably.

[0167] 2. Serves as an Energy Source (ES). This function can be used for device types B and C. CW is actually a type of ES; A-IoT devices can receive CW and store energy. For device type A, because its supported energy storage capabilities are very limited, ES signals other than CW can be omitted. Alternatively, ES signals can be used for device type A.

[0168] 3. Downlink Transmission (DT) function, that is, the device can send indication information to the A-IoT device, thereby triggering the uplink transmission of the A-IoT device.

[0169] 4. Uplink Reception (UR) function, that is, the devices in the communication system can receive uplink information backscattered by A-IoT devices, or receive uplink information actively transmitted by A-IoT devices.

[0170] For example, the device that performs the above functions may be a terminal, a repeater, a relay or a base station, etc. A device may only support one of the above functions, or a device may also support multiple functions at the same time, or a device may support all of the above functions.

[0171] Specifically, the method is as follows.

[0172] FIG2 is an interactive diagram illustrating a communication method based on the ambient IoT according to an embodiment of the present disclosure. As shown in FIG2 , the present disclosure embodiment relates to a communication method based on the ambient IoT, which is used in a communication system 100. The communication system 100 may include a network device 101, a first device 102, and an A-IoT device 103. The method includes:

[0173] Step 2101: The network device determines a set of candidate devices.

[0174] In some embodiments, the candidate device set includes at least one candidate device, and the candidate device can be used to communicate with the A-IoT device.

[0175] In some embodiments, the location of the A-IoT device may be variable, and the device that can assist the A-IoT device in communicating, that is, the alternative device, may also be mobile.

[0176] In some embodiments, to enable communication with an A-IoT device, the candidate device must typically function as at least one of an excitation (CW) source, an energy source (ES), a downlink transmission (DT), and an uplink reception (UR). A single candidate device may also function as all of the aforementioned functions.

[0177] In this solution, excitation and continuous wave both refer to the same signal. The excitation signal can be a continuous wave, but is not limited to this. It can also be other signals used to enable A-IoT devices and A-IoT device groups to send uplink signals based on backscattering. The names of excitation and continuous wave are interchangeable.

[0178] In some embodiments, the candidate device may be a terminal, a repeater, a relay, a base station, or the like.

[0179] In some embodiments, determining the candidate device set may include any of the following:

[0180] Determine the set of candidate devices based on Operation Administration and Maintenance (OAM);

[0181] Based on second information received from at least one alternative device, a set of alternative devices is determined, where the second information is used to indicate device capabilities, and the device capabilities include at least one of supporting energy source ES function, supporting DT function, supporting CW function, and supporting UR function.

[0182] In the above embodiment, the network device can receive capability information reported by the alternative device to determine the alternative device. That is, when a device has at least one capability required to communicate with the A-IoT device, the device can actively report its own capability information. The network device can use it as an alternative device and subsequently make further judgments on the device to determine whether the device can be used to communicate with the A-IoT device.

[0183] In some embodiments, the network device may also obtain the capability information of the device through other means. For example, the network device may notify some devices to report capability information.

[0184] Step 2102: The network device sends third information to at least one candidate device.

[0185] In some embodiments, the network device may send third information to at least one alternative device under a first condition, where the first condition is that the at least one alternative device is in an idle state (RRC_IDLE) or a deactivated state (RRC_INACTIVE), and the third information is used to trigger the at least one alternative device to enter a connected state (RRC_CONNECTED).

[0186] In some embodiments, the candidate device may be the first device, the second device, or the third device, that is, the network device may send the third information to at least one of the first device, the second device, or the third device.

[0187] In some embodiments, the third information may be a paging message.

[0188] In some embodiments, when the device is a terminal device, the network device may select a device in a connected state as a candidate device.

[0189] In some embodiments, the third information is further used to indicate at least one of the following:

[0190] The alternative device supporting the ES function enters the connected state;

[0191] The alternative device supporting the DT function enters the connected state;

[0192] The alternative device supporting the CW function enters the connected state;

[0193] The candidate device supporting the UR function enters the connected state.

[0194] In the above embodiment, when the third information indicates any of the above items, the third information can be used to indicate that only terminals that support the ES, DT, CW or UR function will respond to the third information to enter the connected state.

[0195] In some embodiments, the network device may also select a terminal in an idle state or a deactivated state as a candidate device. In this case, it is necessary to configure the Radio Access Network Notification Area (RAN Notification Area) for the terminal. For example, when the network device obtains that a certain terminal device supports ES, DT, CW or UR functions, the network device releases the terminal into the deactivated state. When configuring the radio access network notification area for the terminal, a list of cells within the coverage of the ambient Internet of Things (ambient IOT) can be configured as the radio access network notification area of ​​the device. At this time, the network device can use the configured terminal device as a candidate device.

[0196] In some embodiments, this step is optional, and the network device may not instruct the candidate device to enter the connected state.

[0197] Step 2103: The network device determines a target candidate device.

[0198] In some embodiments, a network device may determine a target candidate device based on a set of candidate devices. The target candidate device includes at least one of a first device, a second device, and a third device. The first device may be configured to receive an UR signal transmitted uplink by an A-IoT device or group of A-IoT devices, the second device may be configured to send an excitation CW signal to the A-IoT device or group of A-IoT devices, and the third device may be configured to send a downlink DT signal to the A-IoT device or group of A-IoT devices. That is, the network device may determine, from the candidate devices, the first, second, and third devices that perform CW, UR, and DT functions in communication with the A-IoT device as target candidate devices.

[0199] In other words, the target candidate device is the device that the network device is "interested in". The network device comprehensively believes that the target candidate device is more suitable as a device for communicating with the A-IoT device. Therefore, it is necessary to further judge whether the target candidate device can realize the uplink and downlink transmission of the A-IoT device and whether it can meet the performance requirements.

[0200] In some embodiments, the name of the target candidate device may also be “alternative device”, “candidate device”, etc., which is not limited in the present disclosure.

[0201] In some embodiments, the network device may determine multiple groups of target candidate devices, each of which includes a first device, a second device, and a third device, or each of which may include at least one device that has all the functions of the first, second, and third devices. The network device may make a comprehensive determination based on the results of uplink information and / or RRM measurement values ​​of the multiple groups of target candidate devices.

[0202] In some embodiments, the first device, the second device, and the third device may be the same or different devices. That is, receiving the UR, transmitting the CW, and transmitting the DT may be performed independently by three devices or by a single device. For example, if the first device has all of the above functions, it can transmit the DT and CW and receive the UR. In this case, the first device serves as both the second device and the third device.

[0203] In some embodiments, the network device may be the first, second, or third device currently configured for A-IoT transmission, or the network device may be a different device that is independent of the first, second, or third device.

[0204] In some embodiments, the first device may be a single device, or may include multiple devices that receive backscatter-based uplink transmissions (UR) from an A-IoT device. The second device may be a single device, or may include multiple devices that transmit CWs. The third device may be a single device, or may include multiple devices that simultaneously transmit downlink signals (DT) to the A-IoT device.

[0205] In some embodiments, the first device may include a receiving device currently configured to receive uplink signals transmitted via backscatter transmission, and / or one or more candidate devices in a set of candidate devices. The third device may be a device currently configured to transmit downlink signals DT, or may include a candidate device in the set of candidate devices. That is, the first device and the third device may include multiple devices, and the multiple devices may include both devices that have been configured to implement corresponding functions and newly determined devices from the set of candidate devices.

[0206] In some embodiments, the target candidate device is at least one of the following:

[0207] One or more devices in a candidate device set;

[0208] One or more devices configured to transmit a CW signal to an A-IoT device or group of A-IoT devices;

[0209] One or more devices configured to send ES signals to an A-IoT device or group of A-IoT devices;

[0210] One or more devices configured to send DT signals to an A-IoT device or group of A-IoT devices;

[0211] One or more devices configured to receive UR ​​signals backscattered or actively transmitted by an A-IoT device or group of A-IoT devices;

[0212] One or more devices in the candidate device set, and one or more devices that have been configured to send a CW signal to the A-IoT device or group of A-IoT devices;

[0213] One or more devices in the candidate device set, and one or more devices that have been configured to send ES signals to the A-IoT device or group of A-IoT devices;

[0214] One or more devices in the candidate device set, and one or more devices that have been configured to send DT signals to the A-IoT device or group of A-IoT devices;

[0215] One or more devices in the candidate device set, and one or more devices that have been configured to receive UR ​​signals backscattered or actively sent by an A-IoT device or an A-IoT device group.

[0216] Step 2104: The network device sends first information to the target candidate device.

[0217] In some embodiments, the target candidate device may be the first device, the second device, or the third device, that is, the network device may send the first information to at least one of the first device, the second device, or the third device.

[0218] In some embodiments, the first information is used to instruct to perform RRM measurements on an A-IoT device or a group of A-IoT devices.

[0219] In some embodiments, the first information may include at least one of the following:

[0220] CW information, where the CW information includes at least one of CW time-frequency resources, CW transmission beam information, and CW transmission power control information;

[0221] UR information, where the UR information includes at least one of UR time-frequency resources and UR transmission beam information;

[0222] DT information, DT information includes at least one of DT's time-frequency resources, DT's transmission beam information, DT's transmission power, and parameter information used to control uplink transmission of an A-IoT device or A-IoT device group.

[0223] In some embodiments, when the first information indicates the transmission beam information of the CW, the first information may indicate that the CW is directionally transmitted; or the Quasi Co-Location (QCL) information of the CW may be configured by the Radio Resource Control (RRC) layer, or may be obtained implicitly through other methods; or the CW may be omnidirectionally transmitted.

[0224] In some embodiments, when the first information indicates transmission power control information of the CW, the first information may indicate that the transmission power of the CW may be configured using RRC signaling, or may be predefined; or, the first information may indicate that the CW is transmitted using the maximum transmission power of the first device.

[0225] In some embodiments, the first information may indicate the time-frequency resources of the UR, that is, the first information may indicate the channel backscattered by the A-IoT device. For example, the channel backscattered by the A-IoT device may be one or more channels.

[0226] In some embodiments, when the first information indicates the transmission beam information of the UR, the first information may indicate that the UR is directionally transmitting; or the QCL information of the UR may be configured by the unlimited resource control layer RRC, or may be implicitly obtained by other methods; or the UR may be omnidirectionally transmitting.

[0227] In some embodiments, when the first information indicates the transmission beam information of the DT, the first information may indicate that the DT is directionally transmitting; or the QCL information of the DT may be configured by RRC, or may be implicitly obtained through other methods; or the DT may be omnidirectionally transmitting.

[0228] In some embodiments, when the first information indicates the transmission power information of the DT, the first information may indicate that the DT transmission power is configured using RRC signaling or predefined; or, the first information may indicate that the DT transmits using the maximum transmission power of the third device.

[0229] In some embodiments, the parameter information includes at least one of the following:

[0230] Identification of A-IoT devices;

[0231] Identification of the A-IoT device group;

[0232] Power control information of the UR signal backscattered by the A-IoT device;

[0233] A-IoT device backscatter channel;

[0234] The start time and / or duration of the UR signal backscattered by the A-IoT device;

[0235] The UR signal carries uplink information, where the uplink information includes at least one of an identifier of the A-IoT device and an identifier of the A-IoT device group.

[0236] In some embodiments, when the first information indicates an identifier of an A-IoT device or an A-IoT device group, the target candidate device can determine the A-IoT device or A-IoT device group to be found through the above identifier.

[0237] In some embodiments, when the first information indicates power control information of the UR signal backscattered by the A-IoT device, the target candidate device can determine the signal power backscattered by the A-IoT device by receiving the first information. For example, the first information can control the transmission power of the backscattered signal of the A-IoT device, or can control the amplification factor of the reflection amplifier of the A-IoT device type B, etc. through the power control information of the UR signal backscattered by the A-IoT device. In some optional embodiments, the first information can instruct the A-IoT device to operate with the maximum backscatter power. In particular, for A-IoT device type B, the parameter information can be an instruction to turn off the reflection amplifier, or to set its amplification factor to 1.

[0238] In some embodiments, when the first information indicates the backscattered channel of the A-IoT device, the backscattered channel may be a specified channel, or the parameter information may indicate that the A-IoT device may randomly select the backscattered channel, or the parameter information may indicate that the A-IoT device may implicitly calculate the backscattered channel based on other parameters.

[0239] In some embodiments, the first information may indicate the start time and / or duration of the UR signal backscattered by the A-IoT device. The first terminal may determine the start time and / or duration of the UR signal backscattered by the A-IoT device based on this parameter information. For example, the target candidate device may calculate relevant parameters such as the modulation mode and information volume of the UR based on this parameter.

[0240] In some embodiments, the uplink information carried by the UR signal may include not only the identifier of the A-IoT device and the identifier of the A-IoT device group, but also a configured or dynamically indicated sequence. The sequence may also be predefined. The sequences of different A-IoT devices may be different, or the sequences of a group of A-IoT devices may be the same. The sequence may be dedicated to discovering or adjusting devices that support ES, DT, CW, or UR functions. The uplink information may also include a common identifier or sequence for a group of A-IoT devices, as well as an identifier or sequence specific to each A-IoT device.

[0241] In some embodiments, the target candidate device can determine the specific device performing the uplink transmission by receiving the uplink information carried by the UR and according to the identifier of the A-IoT device or the identifier or sequence of the A-IoT device group in the uplink information.

[0242] In some embodiments, the transmission beam information of CW, UR and / or DT may all be directionally transmitted, or may all be omnidirectionally transmitted, or different methods may be used to process the beam directions for different signals.

[0243] In some embodiments, the network device may configure a set of parameters for the target alternative device through the first information, and the above set of parameters may include parameter values ​​of various parameters of the CW, UR and DT functions; or, the network device may also determine multiple sets of parameters for the target alternative device through the first information, wherein each set of parameters includes parameter values ​​of various parameters of the CW, UR and DT functions.

[0244] In step 2105a, the first device determines the transmission beam information of the DT, the transmission power control information of the DT, and the time-frequency resources of the DT based on the first information.

[0245] In some embodiments, the first device may be a target candidate device, that is, the first device may receive the first information, and the first information may be used to indicate the transmission parameters of the DT. In this case, the first device has the capability of downlink transmission of the DT.

[0246] In some embodiments, this step is an optional step. When the A-IoT device can perform uplink transmission autonomously, or when other devices can downlink DT to the A-IoT device, the first device may not determine the transmission beam information of DT, the transmission power control information of DT, and the time-frequency resources of DT.

[0247] Step 2105b: The third device determines the transmission beam information of the DT, the transmission power control information of the DT, and the time-frequency resources of the DT based on the first information.

[0248] In some embodiments, the third device is a device used to send a downlink transmission DT signal to an ambient Internet of Things A-IoT device or an A-IoT device group. At the same time, the third device can also be a target alternative device. At this time, the third device can determine the transmission beam information of the DT, the transmission power control information of the DT, and the time and frequency resources of the DT.

[0249] In some embodiments, this step is optional. When the other device has the DT function, the other device can send a DT signal to the A-IOT device, that is, the other device has the function of a third device, and this step can be omitted. Alternatively, when the third device is not the target candidate device, this step can be omitted.

[0250] Step 2106a: The first device sends a DT signal to the A-IoT device or the A-IoT device group.

[0251] In some embodiments, the first device can send a DT signal to an A-IoT device or an A-IoT device group on the DT's time-frequency resources based on the DT's transmission beam information and the DT's transmission power control information to achieve communication with the A-IoT device.

[0252] In some embodiments, the DT signal can be used to trigger an A-IoT device to perform uplink transmission.

[0253] In some embodiments, this step is optional. When the A-IoT device can perform uplink transmission autonomously, or when other devices can downlink DT to the A-IoT device, the first device may not send a DT signal to the A-IoT device or the A-IoT device group.

[0254] Step 2106b: The third device sends a DT signal to the A-IoT device or the A-IoT device group.

[0255] In some embodiments, the third device is a device used to send a downlink transmission DT signal to an A-IoT device or an A-IoT device group. At the same time, the third device can also be a target alternative device. In this case, the third device can send a DT signal to the A-IoT device or the A-IoT device group.

[0256] In some embodiments, this step is optional. When the other device has the DT function, the other device can send a DT signal to the A-IOT device, that is, the other device has the function of a third device, and this step can be omitted. Alternatively, when the third device is not the target candidate device, this step can be omitted.

[0257] Step 2107a: The first device determines the transmission beam information of the CW, the transmission power control information of the CW, and the time-frequency resources of the CW based on the first information.

[0258] In some embodiments, the first device may be a target candidate device, that is, the first device may receive the first information, and the first information may be used to indicate the transmission parameters of the CW. In this case, the first device has the capability of serving as an excitation CW.

[0259] In some embodiments, the second device may determine the CW transmission beam information, the CW transmission power control information, and the CW time-frequency resources based on the first information. In this case, the first device and the second device are independent of each other.

[0260] In some embodiments, this step is an optional step. When the A-IoT device can actively send an uplink signal, or when other devices can send an excitation CW signal to the A-IoT device, the first device may not determine the CW transmission beam information, CW transmission power control information, and CW time-frequency resources.

[0261] Step 2107b: The second device determines the transmission beam information of the CW, the transmission power control information of the CW, and the time-frequency resources of the CW based on the first information.

[0262] In some embodiments, the second device is a device for sending an excitation CW signal to an ambient Internet of Things (A-IoT) device or an A-IoT device group, and the CW signal is used to enable the A-IoT device or the A-IoT device group to send an uplink UR signal to the first device based on backscattering.

[0263] In some embodiments, the second device may be a target candidate device. In this case, the second device may determine the transmission beam information of the CW, the transmission power control information of the CW, and the time-frequency resources of the CW based on the first information.

[0264] In some embodiments, this step is optional. When the other device has CW functionality, the other device can send a CW signal to the A-IOT device, meaning that the other device has the functionality of the second device, and this step can be omitted. Alternatively, when the second device is not the target candidate device, this step can be omitted.

[0265] Step 2108a: The first device sends a CW signal to the A-IoT device or the A-IoT device group.

[0266] In some embodiments, the first device can send a CW signal to the A-IoT device or A-IoT device group on the CW time-frequency resources based on the CW transmission beam information and CW transmission power control information to achieve communication with the A-IoT device.

[0267] In some embodiments, this step is an optional step. When the A-IoT device can actively send an uplink signal, or when other devices can send an excitation CW signal to the A-IoT device, the first terminal may not send a CW signal to the A-IoT device or the A-IoT device group.

[0268] Step 2108b: The second device sends a CW signal to the A-IoT device or the A-IoT device group.

[0269] In some embodiments, the second device is a device used to send an excitation CW signal to an ambient Internet of Things (A-IoT) device or an A-IoT device group. At the same time, the second device can also be a target candidate device. In this case, the second device can send a CW signal to the A-IoT device or an A-IoT device group.

[0270] In some embodiments, this step is optional. When the other device has CW functionality, the other device can send a CW signal to the A-IOT device, meaning that the other device has the functionality of the second device, and this step can be omitted. Alternatively, when the second device is not the target candidate device, this step can be omitted.

[0271] Step 2109: The A-IoT device or A-IoT device group sends a first signal to the first device based on backscattering or actively.

[0272] In some embodiments, the A-IoT device or the A-IoT device group may backscatter the received CW signal or may actively send the first signal to the first device to achieve uplink transmission.

[0273] In some embodiments, the A-IoT device may adjust the transmission power of the backscattered uplink signal according to the received downlink information, and perform backscatter transmission of the uplink information.

[0274] Step 2110: The first device performs radio resource management (RRM) measurement on the first signal to obtain a measurement result.

[0275] In some embodiments, the first device may receive the uplink signal backscattered by the A-IoT device and perform RRM measurement, and report the uplink information reception result and / or RRM measurement value of the A-IoT device to the network device.

[0276] In some embodiments, the first device may also perform processing directly based on the RRM measurement value.

[0277] Step 2111: The first device sends a measurement result and / or a reception result to the network device.

[0278] In some embodiments, the first device may send measurement results to the network device. The measurement results may be used to assist the network device in determining a target device suitable for communicating with an A-IoT device or group of A-IoT devices. Specifically, based on the measurement results, the network device may determine whether the candidate device is suitable for transmitting ES signals, CWs, downlink information (DT) to the A-IoT device, and / or for receiving uplink signals from the A-IoT device.

[0279] In some embodiments, the measurement result is a result of a radio resource management RRM measurement performed by the first device on the first signal, and the first signal is an uplink UR signal sent by an ambient Internet of Things A-IoT device or an A-IoT device group to the first device based on backscatter or actively.

[0280] In some embodiments, the first device can send the reception result to the network device. In other words, the first device can report the reception status of the first signal to the network device, such as whether the first device correctly receives the first signal, that is, whether the first device correctly receives the UR signal.

[0281] In some embodiments, when the uplink signal backscattered by the A-IoT device is distributed across multiple channels, the first device can determine whether it can correctly receive the uplink information of the A-IoT device on each of the multiple channels and perform RRM measurements on each of the multiple channels. In this case, the network device can receive measurement results obtained by multiple first devices for the same first signal.

[0282] In some embodiments, the measurement results may include at least one of the following:

[0283] Reference signal received power RSRP;

[0284] Reference signal received quality RSRQ;

[0285] Received signal strength indication RSSI;

[0286] Signal to Interference and Noise Ratio SINR;

[0287] Bit error rate BER;

[0288] Block error rate BLER.

[0289] Step 2112: The network device determines the target device.

[0290] In some embodiments, the network device may determine a target device based on the measurement results, where the target device is suitable for communicating with the A-IoT device or group of A-IoT devices.

[0291] In some embodiments, the target device is one or more devices in the target candidate device, the target candidate device is one or more devices in the candidate device set, and the candidate device set includes at least one candidate device.

[0292] In some embodiments, at least one candidate device, the target candidate device, and the target device each include at least one of the following:

[0293] A first device is configured to receive an uplink UR signal sent by an A-IoT device or an A-IoT device group;

[0294] A second device is configured to send an excitation CW signal to an A-IoT device or a group of A-IoT devices;

[0295] The third device is used to send a downlink transmission DT signal to the A-IoT device or A-IoT device group.

[0296] In some embodiments, the network device can determine, based on the measurement results, whether the target alternative device and / or the device that has been configured to communicate with the A-IoT device or the A-IoT device group is suitable for sending at least one of the ES signal, CW signal, and DT signal to the A-IoT device or the A-IoT device group, and / or whether it is suitable for receiving the UR signal sent by the A-IoT device or the A-IoT device group, thereby determining the target device.

[0297] In some embodiments, the network device may determine one or more target candidate devices and / or devices configured to communicate with the A-IoT device or A-IoT device group as target devices based on the measurement results when the second condition is met.

[0298] In the above embodiment, the second condition is at least one of the following:

[0299] There is a first device that can correctly receive a UR signal sent by an A-IoT device or a group of A-IoT devices, and / or a measurement result is greater than or equal to a preset value;

[0300] There are multiple first devices, and the multiple first devices jointly receive the UR signal sent by the A-IoT device or the A-IoT device group to meet the receiving performance. The multiple first devices correctly receive the UR signal sent by the A-IoT device or the A-IoT device group, and / or the measurement result is greater than or equal to the preset value.

[0301] In the above embodiment, the first device is the target candidate device. In this case, there may be one or more first devices that receive the UR signal sent by the A-IoT device or the A-IoT device group. The network device can judge whether the first device is suitable for performing the above UR ​​function by integrating the reception conditions of one or more first devices. Optionally, when the first device can serve as at least one of the second device and the third device (in other words, the first device has the UR function, the DT function, and the CW function), it can be judged whether the first device is suitable for performing the above ES, DT, CW, or UR function based on the reception conditions and / or measurement results of multiple first devices.

[0302] In the above embodiment, the second device can be used as a target candidate device. In this case, there may be one or more second devices that send an excitation CW signal to the A-IoT device or A-IoT device group. The network device can judge whether the second device is suitable for performing the above CW function by integrating the transmission conditions of one or more second devices. Optionally, when the second device can serve as at least one of the first device and the third device (in other words, the second device has a UR function, a DT function, and a CW function), it can be judged whether the second device is suitable for performing the above ES, DT, CW, or UR function based on the transmission conditions and / or measurement results of multiple second devices.

[0303] In the above embodiment, the third device can be used as a target alternative device. At this time, there may be one or more third devices that transmit DT signals to the A-IoT device or A-IoT device group. The network device can judge whether the third device is suitable for performing the above DT function by integrating the transmission conditions of one or more third devices. Optionally, when the third device can be used as at least one of the first device and the second device (in other words, the third device has a UR function, a DT function, and a CW function), it can be judged whether the third device is suitable for performing the above ES, DT, CW or UR function based on the transmission conditions and / or measurement results of multiple third devices. In the above example, the target alternative device may include at least one of the first device, the second device, and the third device, that is, there are one or more first devices, second devices, and third devices. The network device can determine whether one or more first devices, second devices, and third devices are suitable for performing the above ES, DT, CW or UR functions based on the measurement results and / or reception or transmission conditions of each device.

[0304] In the above embodiment, the network device can configure a set of parameters for the first device, including parameter values ​​of various parameters of the CW, UR and DT functions. At this time, the network device can determine whether the first device can be used to support the transmission of the A-IoT device under this set of parameter values ​​based on the measurement value.

[0305] In the above embodiment, the network device can configure multiple sets of parameters for the first device, each set of parameters includes parameter values ​​of various parameters of the CW, UR and DT functions. At this time, the first device can perform a communication and RRM measurement for each set of parameter values ​​to obtain a measurement value. The network device can determine whether the first device can be used to support the transmission of the A-IoT device under multiple sets of parameter values ​​based on the measurement value, and can compare the reception conditions under multiple sets of parameter values ​​to select parameter values ​​with better transmission effect.

[0306] In some embodiments, when the first device can function as a network device, the first device can communicate with the A-IoT device using a set of parameter values, where the set of parameter values ​​includes parameter values ​​for each parameter of the CW, UR, and DT functions. The first device can determine, based on measurement results, whether the first device can be used to support transmission of the A-IoT device under the set of parameter values. In some embodiments, the target device can be used to:

[0307] Sending a CW signal to an A-IoT device or a group of A-IoT devices;

[0308] Sending an ES signal to an A-IoT device or a group of A-IoT devices;

[0309] Sending a DT signal to an A-IoT device or a group of A-IoT devices;

[0310] Receive UR ​​signals backscattered or actively sent by an A-IoT device or A-IoT device group.

[0311] In some embodiments, when there is only one A-IoT device performing uplink transmission, a target device that performs ES, DT, CW, or UR functions applicable to the A-IoT device can be determined.

[0312] In some embodiments, there may be multiple A-IoT devices (e.g., an A-IoT device group) performing uplink transmission. If the uplink information of multiple A-IoT devices is consistent, such as the same group identifier or sequence, the backscattered uplink signals of multiple A-IoT devices are superimposed and enhanced, which is conducive to the network device to quickly discover devices that can support the ES, DT, CW or UR functions of a group or all A-IoT devices, and can quickly determine multiple devices suitable for communicating with A-IoT devices. For example, when a group or all A-IoT devices are close to each other, the device that performs ES, DT, CW or UR functions applicable to one of the A-IoT devices may also be applicable to multiple other devices that are close to each other. Therefore, after determining the corresponding target device for an A-IoT device, the device may also be applicable to other A-IoT devices that are performing uplink transmission at the same time.

[0313] In some embodiments, different A-IoT devices or different groups of A-IoT devices may be far away from each other, and the devices suitable for performing ES, DT, CW or UR functions may be different.

[0314] The positioning measurement method involved in the embodiments of the present disclosure may include at least one of steps 2101 to 2112.

[0511] The following is an exemplary introduction to the above method.

[0512] The method shown in the embodiment of the present disclosure relates to a method for discovering auxiliary devices for A-IoT transmission.

[0513] An important application of A-IoT technology is the inventory and monitoring of large-scale items or materials. At this time, the number of A-IoT terminal devices is very large. In order to reduce the complexity of A-IoT devices, A-IoT devices can only support simple transmission and reception operations. However, A-IoT devices may not support processing operations such as related measurements of radio resource management (RRM). The related measurement values ​​of RRM can be reference signal received power (RSRP), reference signal received quality (RSRQ) or received signal strength indication (RSSI). Therefore, when the A-IoT device is unable to perform RRM-related measurements, how to measure the channel status of the A-IoT device in the network and how to determine the device suitable for communicating with the A-IoT device are the problems that this solution needs to solve.

[0514] To support data transmission between A-IoT devices, the transmission network needs to support the following four functions. The network can include multiple devices, each of which can support one or more of the following functions.

[0515] 1. As an excitation CW function, it is only used for device type A and device type B. A-IoT devices can achieve uplink transmission through backscatter CW.

[0516] 2. Serves as an Energy Source (ES). This function can be used for device types B and C. CW is actually a type of ES; A-IoT devices can receive CW and store energy. For device type A, because its supported energy storage capabilities are very limited, ES signals other than CW can be omitted. Alternatively, ES signals can be used for device type A.

[0517] 3. Downlink transmission DT function, for example, sending indication information to the A-IoT device to trigger the uplink transmission of the A-IoT device.

[0518] 4. Uplink reception (UR) function, which means that it can receive uplink information backscattered by A-IoT devices, or can receive uplink information actively transmitted by A-IoT devices.

[0519] The devices that perform the above four functions may be terminals, transponders, relays, or base stations, among others. A device in a transmission network may support only one of the above functions. Alternatively, a device may support multiple or all of the above functions simultaneously.

[0520] Since A-IoT devices only support simple transmission and reception operations, A-IoT devices may not support related measurements of radio resource management (RRM). A network that supports A-IoT devices needs to discover and adjust devices that support A-IoT device communications and perform the above-mentioned ES, DT, CW or UR functions. In order to support effective uplink and downlink communications of A-IoT devices, the method proposed in this solution needs to perform RRM measurements on A-IoT devices, determine their corresponding channel states, and determine one or more devices that assist A-IoT device communications based on the channel states of the A-IoT devices to support the above-mentioned ES, DT, CW or UR functions. Among them, the location of the A-IoT device may be variable, and the device that can assist the A-IoT device communications may be mobile.

[0521] For alternative devices used to perform the above-mentioned ES, DT, CW or UR functions, one or more alternative devices can be used to transmit downlink information to the A-IoT device. For example, one or more alternative devices can be used to transmit an excitation signal (CW) to the A-IoT device, and / or one or more alternative devices can be used to receive the uplink signal transmitted by the A-IoT device based on backscattering. According to the reception of the uplink signal, it can be determined whether the corresponding alternative device can correctly receive the uplink information of the A-IoT device, and the measurement quantity reflecting the channel state of the A-IoT device can be obtained by measuring the above-mentioned uplink signal. The measurement quantity can be an RRM measurement of the uplink signal of the A-IoT device. RRM measurements can include reference signal received power (RSRP), reference signal received quality (RSRQ) or received signal strength indication (RSSI) or signal to interference and noise ratio (SINR), etc. RRM measurement can also refer to the bit error rate (BER) or block error rate (BLER) of the A-IoT transmission calculated based on RSRP, RSRQ, RSSI or SINR, etc.

[0522] Whether the above-mentioned alternative device can correctly receive the uplink information of the A-IoT device can directly reflect whether the A-IoT device can communicate normally with the device that performs the CW, UR and DT functions (i.e., the alternative device). RRM measurement can more accurately indicate the channel status of the A-IoT device. The RRM measurement value is directly related to the reception performance of the uplink signal of the A-IoT device, which indicates whether the CW can support the uplink transmission of the A-IoT device, and because the A-IoT device can perform backscattering of the CW, it means that the reception strength of the CW exceeds a certain threshold. For example, the RRM measurement value can simultaneously indicate the performance of the uplink and downlink transmission of the A-IoT device.

[0523] In summary, RRM measurements can indicate whether a candidate device is suitable for CW transmission. Furthermore, RRM measurements can indicate whether a candidate device is suitable for transmitting ES signals and transmitting downlink information (DT) to A-IoT devices. For a candidate device performing UR functions, even if the candidate device is not used for CW, temporary CW transmission can still be enabled to determine whether the candidate device is suitable for UR functions.

[0524] The following example specifically illustrates a method for discovering auxiliary devices for A-IoT transmission. FIG9 shows a schematic diagram of the specific flow of the example.

[0525] Step 1: The network device determines a set of candidate devices for ES, DT, CW, or UR functions. The set of candidate devices includes one or more candidate devices, which can be used for the same or different ES, DT, CW, or UR functions.

[0526] Specifically, the network device can determine a set of alternative devices based on OAM, or the network device can determine a set of alternative devices based on the capabilities of the device. For example, the network device can receive capability indication information that supports becoming an ES, DT, CW or UR function, and determine the alternative devices based on the capability indication information. For example, the network side device can obtain the capability information of the device through the capability report or notification of the device. If the device is a terminal, the network side can select the terminal in the RRC_CONNECTED state as an alternative device. Optionally, the network side device can trigger the terminal to enter the RRC_CONNECTED state and become an alternative device through a paging message. Furthermore, the above-mentioned paging message can carry indication information to indicate that only terminals that support becoming an ES, DT, CW or UR function will respond to paging and enter the RRC_CONNECTED state.

[0527] Alternatively, the network can select a terminal in the RRC_IDLE or RRC_INACTIVE state as a candidate device. For example, if the network knows that the terminal supports ES, DT, CW, or UR functions, it releases the terminal into the RRC_INACTIVE state and configures the RAN (RAN Notification Area). The cell list corresponding to the ambient IoT coverage area can be configured as the RAN. In this case, the network device can select the RRC_INACTIVE UE as a candidate device.

[0528] Step 2: The network device selects the first, second, and third devices that can communicate with the A-IoT device and perform the CW, UR, and DT functions. Specifically, the first device is used to transmit the CW to the A-IoT device (i.e., the second device mentioned above); the second device is used to receive the uplink signal UR transmitted by the A-IoT device based on backscatter (i.e., the first device mentioned above); and the third device is used to transmit the downlink information DT to the A-IoT device.

[0529] When discovering and adjusting devices that support A-IoT device communication, the following situations can be considered depending on whether a device in the candidate device set is used as the first device:

[0530] 1. The first device is one or more candidate devices in a set of candidate devices.

[0531] 2. The first device is one or more devices that are currently configured to transmit CWs.

[0532] 3. The first device is one or more devices that are currently configured to transmit ES signals.

[0533] 4. The first device is one or more devices that are currently configured to transmit a downlink signal DT to the A-IoT device.

[0534] 5. The first device is one or more devices currently configured to receive the uplink signal UR backscattered by the A-IoT device.

[0535] 6. The first device includes one or more candidate devices in the candidate device set, and one or more devices currently configured to transmit CWs.

[0536] 7. The first device includes one or more candidate devices in the candidate device set, and one or more devices currently configured to transmit ES signals.

[0537] 8. The first device includes one or more candidate devices in the candidate device set, and one or more devices currently configured to transmit a downlink signal DT to the A-IoT device.

[0538] 9. The first device includes one or more candidate devices in the candidate device set, and one or more devices currently configured to receive the uplink signal UR backscattered by the A-IoT device.

[0539] In some embodiments, the second device may include a receiving device currently configured to receive an uplink signal of a backscatter transmission, and / or one or more alternative devices in a set of alternative devices. The third device may be a device currently configured to transmit a downlink signal DT, or may include a third alternative device in the set of alternative devices.

[0540] The first, second, and third devices described above may be the same or different devices. The network device may be the first, second, or third device currently configured for A-IoT transmission, or the network devices may be different devices. The first device may be a single device, or may include multiple devices that transmit CWs. The second device may be a single device, or may include multiple devices that receive backscatter-based uplink transmissions (URs) from A-IoT devices. The third device may be a single device, or may include multiple devices that simultaneously transmit downlink signals (DTs) to A-IoT devices.

[0541] Step 3: The network device determines and transmits control information of CW, UR and DT to the first device, the second device and the third device.

[0542] The control information of the CW may include but is not limited to at least one of the following:

[0543] 1.CW time and frequency resources.

[0544] 2. CW transmission beam information. For example, the CW can be directional transmission. Alternatively, the CW Quasi Co-Location (QCL) information can be configured by the Radio Resource Control (RRC) layer or can be implicitly obtained through other methods. Alternatively, the CW can also be omnidirectional transmission.

[0545] 3. CW transmission power control information. For example, the CW transmission power can be configured using RRC signaling or predefined. Alternatively, the CW can be transmitted using the maximum transmission power of the first device.

[0546] In some embodiments, the control information of the UR may be configured by the network device or may be dynamically indicated by the network device. The control information of the UR includes but is not limited to at least one of the following information:

[0547] 1. UR time-frequency resources. For example, the backscatter channel of the A-IoT device can be one or more channels.

[0548] 2. UR transmission beam information. For example, the UR may be directional. Alternatively, the UR's QCL information may be configured by RRC or implicitly obtained through other methods. Alternatively, the UR may be omnidirectional.

[0549] In some embodiments, the control information of the DT may be configured by the network device or may be dynamically indicated by the network device. The control information of the DT includes but is not limited to one or more of the following information:

[0550] 1.DT’s time and frequency resources.

[0551] 2. DT transmission beam information. DT can be directional. Alternatively, DT's QCL information can be configured by RRC or implicitly obtained through other methods. Alternatively, DT can be omnidirectional.

[0552] 3. DT transmission power. The DT transmission power can be configured using RRC signaling or predefined. Alternatively, the CW can be transmitted using the maximum transmission power of the third device.

[0553] In some embodiments, the DT may include one or more of the following parameters for controlling uplink transmission of the A-IoT device.

[0554] 1. Indicate one, a group, or all A-IoT devices.

[0555] 2. Power control information for the uplink signal backscattered by the A-IoT device. For example, this information controls the transmission power of the backscattered signal from the A-IoT device, or the amplification factor of the reflective amplifier for type B A-IoT devices. Alternatively, the A-IoT device can operate at maximum backscattered power. Specifically, for type B A-IoT devices, this information can indicate that the reflective amplifier of the A-IoT device is disabled, or that the amplification factor of the A-IoT device is set to 1.

[0556] 3. The backscatter channel of the A-IoT device. The backscatter channel can be a specified channel, or it can indicate that the A-IoT device can randomly select a backscatter channel, or it can indicate that the A-IoT device implicitly calculates the backscatter channel based on other parameters.

[0557] 4. The start time and / or length of the uplink signal transmitted by the A-IoT device based on backscatter.

[0558] 5. Uplink information transmitted by the A-IoT device based on backscatter. The uplink information can be the unique identifier of the A-IoT device, the group identifier of the A-IoT device, or a configured or dynamically indicated sequence. The sequence can also be predefined. The sequences of different A-IoT devices can be different, or the sequences of a group of A-IoT devices can be the same. The sequence can be dedicated to discovering or adjusting devices that support ES, DT, CW or UR functions. The uplink information can also include a common identifier or sequence for a group of A-IoT devices, as well as an identifier or sequence specific to each A-IoT device.

[0559] In the above embodiments, CW, UR and / or DT may all be directional, or all be omnidirectional, or different methods may be used to process the beam directions.

[0560] Step 4: The first, second, and third devices communicate with the A-IoT device according to the control information in step 3, receive the uplink signal backscattered by the A-IoT device and perform RRM measurements, and report the reception results and / or RRM measurement values ​​to the network device.

[0561] Specifically, the third device can send downlink information to the A-IoT device according to the received control information, triggering the uplink transmission of the A-IoT device. The first device can set the transmission power and beam of the CW according to the received control information, transmit the CW on the indicated time-frequency resources, and the A-IoT device can perform uplink transmission based on the backscattered CW. The A-IoT device can adjust the transmission power of the backscattered uplink signal according to the received downlink information, and perform backscatter transmission of uplink information. The second device can receive the backscattered uplink signal of the A-IoT device and perform RRM measurement, and report the uplink information reception result and / or RRM measurement value of the A-IoT device to the network device. The second device can also process directly according to the RRM measurement value.

[0562] Step 5: The network device determines whether the alternative device and / or the currently configured communication device for receiving the A-IoT device is suitable for transmitting ES signals, CW, downlink information DT to the A-IoT device, and / or whether it is suitable for receiving uplink signals of the A-IoT device.

[0563] 1) For the first candidate device in the candidate device set used as the first device, one of the following methods may be used:

[0564] When at least one second device correctly receives uplink information from the A-IoT device and / or the RRM measurement value is higher than a preset threshold, the first candidate device may be configured to perform one or more of the following functions:

[0565] 1. The first candidate device can be used to transmit CW. Accordingly, at least one second device is a receiving device for receiving the backscattered uplink signal of the A-IoT device.

[0566] 2. The first alternative device can be used to transmit ES signals.

[0567] 3. The first candidate device may be used to transmit downlink information DT to the A-IoT device.

[0568] 4. The first candidate device may be used to receive the backscattered uplink signal UR of the A-IoT device.

[0569] If multiple or all second devices can meet the required reception performance when performing joint reception, the first candidate device can be used to perform one or more of the following functions:

[0570] 1. The first candidate device can be used to transmit CW. Accordingly, multiple or all second devices are receiving devices that receive backscattered uplink signals from A-IoT devices.

[0571] 2. The first alternative device can be used to transmit ES signals.

[0572] 3. The first candidate device may be used to transmit downlink information DT to the A-IoT device.

[0573] 4. The first candidate device may be used to receive the backscattered uplink signal UR of the A-IoT device.

[0574] 2) For the second candidate device in the candidate device set used as the second device, one of the following methods may be used:

[0575] When the second candidate device correctly receives the uplink information of the A-IoT device and / or the RRM measurement value is higher than a preset threshold, the second candidate device may be configured to perform one or more of the following functions:

[0576] 1. The second candidate device can be used to receive the backscattered uplink signal UR from the A-IoT device. In this case, the first device is the device that transmits CW.

[0577] 2. A second alternative device may be used to transmit CW.

[0578] 3. A second alternative device may be used to transmit ES signals.

[0579] 4. The second candidate device may be used to transmit downlink information DT to the A-IoT device.

[0580] If multiple or all second devices including the second candidate device can meet the required reception performance when performing joint reception, the second candidate device may be used to perform one or more of the following functions:

[0581] 1. The second candidate device can be used to jointly receive the backscattered uplink signal of the A-IoT device. In this case, the first device is the device that transmits CW.

[0582] 2. A second alternative device may be used to transmit CW.

[0583] 3. A second alternative device may be used to transmit ES signals.

[0584] 4. The second candidate device may be used to transmit downlink information DT to the A-IoT device.

[0585] 3) For the third candidate device in the candidate device set used as the third device, one of the following methods may be used:

[0586] When at least one second device correctly receives the uplink information of the A-IoT device and / or the RRM measurement value is higher than a preset threshold, or if multiple or all second devices can meet the required reception performance when performing joint reception, the third alternative device can be used to perform one or more of the following functions:

[0587] 1. The third candidate device can be used to transmit downlink information DT to the A-IoT device.

[0588] 2. The third alternative device can be used to transmit ES signals.

[0589] 3. A third alternative device may be used to transmit CW.

[0590] 4. The third candidate device may be used to receive the backscattered uplink signal UR of the A-IoT device.

[0591] When at least one second device correctly receives the uplink information of the A-IoT device and / or the RRM measurement value is higher than the preset threshold, or when multiple or all second devices can meet the required reception performance when performing joint reception,

[0592] The device currently configured to transmit CWs, acting as the first device, is still suitable for transmitting CWs;

[0593] A device currently configured to transmit downlink information to an A-IoT device, used as a third device, is still suitable for transmitting CWs;

[0594] For device X, which is currently configured to receive uplink information backscattered by an A-IoT device and serves as a second device, when device X can correctly receive the uplink information of the A-IoT device and / or the RRM measurement value is higher than a preset threshold, or if multiple or all second devices including device X can meet the required reception performance when performing joint reception, device X is still suitable for receiving the uplink information backscattered by the A-IoT device.

[0595] Using the above example, when the uplink signal backscattered by the A-IoT device is distributed on multiple channels, in step four, the second device can determine whether it can correctly receive the uplink information of the A-IoT device on multiple channels, perform RRM measurements on each channel, and report the uplink information reception results and / or RRM measurement values ​​of the A-IoT device to the network device.

[0596] Using the above example, the network device can select one or more groups of devices, each group of devices including a first device, a second device, and a third device, thereby integrating the results of receiving the uplink information backscattered by the A-IoT device and / or the RRM measurement values ​​of the multiple groups of devices to determine whether the alternative device is suitable for performing the above-mentioned ES, DT, CW or UR functions. For a group of first devices, second devices, and third devices, in step 2, the network device can determine a set of parameters, including parameter values ​​of each parameter of the above-mentioned CW, UR, and DT functions, to determine whether the alternative devices for the first, second, and third devices can be used to support the transmission of the A-IoT device under this set of parameter values. Alternatively, the network device can determine multiple sets of parameters, each set of parameters including parameter values ​​of each parameter of the above-mentioned CW, UR, and DT functions, so that multiple sets of parameters can be tried to determine whether the alternative devices for the first, second, and third devices can be used to support the transmission of the A-IoT device, as well as a more optimal set or sets of parameters.

[0597] Using the above example, when a candidate device is used for only one of the first, second, or third devices, the method in step 5 can be used to determine whether the candidate device performs the ES, DT, CW, or UR function. When a candidate device is used for multiple of the first, second, and third devices, the method in step 5 can be used to comprehensively determine whether the candidate device performs the ES, DT, CW, or UR function.

[0598] Using the above example, when only one A-IoT device is indicated for backscattering, the device that performs the ES, DT, CW, or UR function applicable to the one A-IoT device can be determined. When a group or all A-IoT devices are indicated for backscattering, assuming that the uplink information of a group of A-IoT devices, such as the group identifier or sequence, is the same, the uplink signals backscattered by the group of A-IoT devices are superimposed and enhanced, which is conducive to quickly discovering the device that performs the ES, DT, CW, or UR function that supports a group or all A-IoT devices. For example, a group or all A-IoT devices may be relatively close, so the applicable device that performs the ES, DT, CW, or UR function is the same. Using this method, the device that performs the ES, DT, CW, or UR function may be different for different A-IoT devices or different groups of A-IoT devices.

[0599] In summary, the above embodiments of the present solution, by determining an alternative device and using the alternative device to communicate with the A-IoT device, obtain the uplink transmission signal of the A-IoT device, and measure the above uplink signal, it is possible to determine the device suitable for communicating with the A-IoT device based on the uplink signal.
