[0130] A-IoT is a new IoT technology. Compared with traditional IoT technology, a significant feature is that A-IoT terminals in the network

[0131] A-IoT UEs (also known as A-IoT devices or A-IoT tags) are available in large numbers, 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 in warehouses, eliminating the cost of battery configuration and replacement.

[0132] 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.

[0133] To reduce the complexity of A-IoT devices, they typically only support simple transmit and receive 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). This solution addresses the issue of measuring the channel status of A-IoT devices in the network.

[0134] To address the above issues, the present disclosure proposes a communication method based on the ambient Internet of Things, which can obtain the channel state of the A-IoT device by receiving the uplink signal transmitted by the A-IoT device based on backscattering and measuring the uplink signal, wherein the RRM measurement value includes RSRP, RSRQ and / or RSSI, etc., so that the network can manage the A-IoT device based on the above RRM measurement value.

[0135] 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.

[0136] 1. As an excitation signal, it is generally a continuous wave (CW) function and is only used by Devices A and B. A-IoT devices can achieve uplink transmission through backscatter CW. In this patent, CW refers to the excitation signal.

[0137] 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.

[0138] 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.

[0139] 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.

[0140] 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.

[0141] Specifically, the method is as follows.

[0142] Figure 2 is an interactive diagram of a communication method based on the ambient IoT according to an embodiment of the present disclosure. As shown in Figure 2, 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 first device 101 and an A-IoT device 102. The method includes:

[0143] Step 2101: The network device sends first information to the first device.

[0144] In some embodiments, the first information may be used to indicate that RRM measurements are to be performed on an A-IoT device or a group of A-IoT devices. Optionally, the first information may also be used to indicate other information.

[0145] In some embodiments, the network device may allocate time-frequency domain resources specifically for performing RRM measurements on an A-IoT device or a group of A-IoT devices, and the first device may perform RRM measurements on the time-frequency domain resources; or the first device may determine on its own which time-frequency domain resources to perform RRM measurements on (for example, when the first device is a network device, the first device has the ability to determine time-frequency domain resources).

[0146] In some embodiments, the first information includes at least one of the following:

[0147] 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;

[0149] 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.

[0150] In the solution of the present disclosure, continuous wave and excitation 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 can be interchangeable.

[0151] 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.

[0164] In some embodiments, when the first information indicates an identifier of an A-IoT device or an A-IoT device group, the first device can determine the A-IoT device or A-IoT device group to be found through the above identifier.

[0165] In some embodiments, when the first information indicates power control information of the UR signal backscattered by the A-IoT device, the first 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 backscattered transmission power of the A-IoT device, or 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 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.

[0166] 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.

[0167] 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 the parameter information. For example, the first device may calculate relevant parameters such as the modulation mode and information volume of the UR based on the parameter information.

[0168] In some embodiments, the uplink information carried by the UR signal may be, in addition to the identifier of the A-IoT device and the identifier of the A-IoT device group, 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.

[0169] In some embodiments, the first 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.

[0170] 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.

[0171] In some embodiments, the first device may perform the function of a network device, that is, the first device may act as a network device and determine the first information by itself.

[0172] In some embodiments, the first device may be a device, or the first device may be a device including a plurality of devices capable of receiving an uplink signal UR based on backscattering of an A-IoT device and performing RRM measurement on the uplink signal UR.

[0173] In some embodiments, this step is optional. When the first device can serve as a network device, the first device may not receive the first information sent by the network device.

[0174] Step 2102: The first device sends first information to the second device.

[0175] In some embodiments, the second device may be configured to send an excitation signal CW to an A-IoT device or a group of A-IoT devices, that is, the second device may have the capability of transmitting CW.

[0176] In some embodiments, the first device can act as the second device to send an excitation signal CW to an A-IoT device or an A-IoT device group. At this time, the first device has the ability to receive UR, perform RRM measurement on UR, and send an excitation signal CW to the A-IoT device or the A-IoT device group.

[0177] In some embodiments, the second device may be determined by a network device, and when the first device may serve as a network device, the second device may be determined by the first device.

[0178] In some embodiments, when a second device is used to transmit a CW excitation signal to an A-IoT device or group of A-IoT devices, the first device may transmit first information to the second device. The first information may indicate relevant parameters for the second device to transmit the CW, such as at least one of the CW time-frequency resources, CW transmission beam information, and CW transmission power control information. The second device may transmit the CW signal in accordance with the instructions in the first information.

[0179] In some embodiments, the second device may be a single device, or may include multiple devices that send an excitation signal CW to an A-IoT device or an A-IoT device group.

[0180] In some embodiments, when the first device can transmit a CW signal as the second device, this step is optional.

[0181] Step 2103: The first device sends the first information to the third device.

[0182] In some embodiments, the third device can be used to send a downlink transmission DT signal to the A-IoT device or the A-IoT device group, that is, the third device has the ability to transmit downlink information to the A-IoT device or the A-IoT device group.

[0183] In some embodiments, the first device can act as a third device to send a downlink transmission DT signal to an A-IoT device or an A-IoT device group, and has the ability to receive UR, perform RRM measurements on UR, and send a downlink transmission DT signal to the A-IoT device or an A-IoT device group.

[0184] In some embodiments, the third device may be determined by a network device, and when the first device can serve as a network device, the third device may be determined by the first device.

[0185] In some embodiments, when a third device is used to send a downlink transmission DT signal to an A-IoT device or an A-IoT device group, the first device may send first information to the third device. In this case, the first information may indicate relevant parameters for the third device when sending the downlink transmission DT signal, such as at least one of the DT time-frequency resources, DT transmission beam information, DT transmission power, and parameter information for controlling uplink transmission of the A-IoT device or A-IoT device group.

The CW signal is used to enable the A-IoT device or A-IoT device group to transmit the first signal based on backscattering, and the DT signal is used to trigger the A-IoT device or A-IoT device group to transmit the first signal. That is, after receiving the DT signal, the A-IoT device or A-IoT device group can perform uplink transmission. In this context, after receiving the CW signal, the A-IoT device or A-IoT device group can backscatter the CW signal to achieve uplink transmission.

[0191] In some embodiments, 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; and sends a DT signal to the A-IoT device or A-IoT device group on the time-frequency resources of the DT according to the transmission beam information of the DT and the transmission power control information of the DT.

[0193] In some embodiments, this step is an optional step. In some optional implementations, other devices (second device, third device) may send DT and / or CW signals to the A-IoT device or A-IoT device group.

[0194] Step 2105: The third device sends a DT signal to the A-IoT device.

[0195] In some embodiments, the DT signal can be used to trigger an A-IoT device or a group of A-IoT devices to send a first signal. That is, the DT signal can be used to trigger an A-IoT device to perform uplink transmission.

[0196] In some embodiments, optionally, the A-IoT device may not need to receive a DT signal before performing uplink transmission. The A-IoT device may perform uplink transmission on its own, and in this case, the third device may not send a DT signal to the A-IoT device.

[0197] In some embodiments, it is not necessarily the third device that sends the DT signal to the A-IoT device. The first device or the second device may also send the DT signal to the A-IoT device to trigger it.

[0198] In some embodiments, the A-IoT device can determine parameter information used to control the uplink transmission of the A-IoT device or the A-IoT device group by receiving a DT signal sent by a third device, and the third device is used to send a downlink transmission DT signal to the A-IoT device or the A-IoT device group.

[0205] 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.

[0206] In some embodiments, the A-IoT device or the A-IoT device group may adjust the parameters of the backscattered uplink signal according to the above parameter information.

[0207] In some embodiments, the third device is not necessarily the one that sends parameter information to the A-IoT device. The first device or the second device may also send parameter information to the A-IoT device.

[0208] In some embodiments, when the first device can act as a third device to send a DT signal to the A-IoT device, this step is optional.

[0209] Step 2106: The second device sends a CW signal to the A-IoT device.

[0210] In some embodiments, the CW signal may be used to enable an A-IoT device or a group of A-IoT devices to transmit a first signal based on backscatter.

[0211] In some embodiments, the A-IoT device may backscatter the CW signal and adjust the backscattered signal to obtain an uplink UR signal.

[0212] In some embodiments, it is not necessarily the second device that sends the CW signal to the A-IoT device. The first device or the third device may also send the CW signal to the A-IoT device to enable the A-IoT device or the A-IoT device group to send the first signal based on backscattering.

[0213] In some embodiments, when the first device can act as the second device to send a CW signal to the A-IoT device, this step is optional.

[0214] Step 2107: The A-IoT device or the A-IoT device group sends a first signal to the first device.

[0215] In some embodiments, the first signal is an uplink UR signal sent by the A-IoT device or A-IoT device group based on backscattering or actively sent, that is, the first signal can also be actively sent by the A-IoT device to the first device.

[0216] In some embodiments, the first signal is triggered by the A-IoT device or the A-IoT device group receiving a DT signal, and / or the first signal is backscattered by the A-IoT device or the A-IoT device group based on a CW signal, wherein the DT signal and / or the CW signal is sent by any one of the first device, the second device, and the third device to the A-IoT device or the A-IoT device group.

[0217] Step 2108: The first device performs radio resource management (RRM) measurement on the first signal to obtain a measurement value of the measurement quantity.

[0218] In some embodiments, the measurement value may be used to indicate the channel quality between the first device and the A-IoT device or group of A-IoT devices.

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

[0220] Reference signal received power RSRP;

[0221] Reference signal received quality RSRQ;

[0222] Received signal strength indication RSSI;

[0223] Signal to Interference and Noise Ratio SINR;

[0224] Bit error rate BER;

[0225] Block error rate BLER.

[0226] Step 2109: The first device sends the measured value of the measurement quantity to the network device.

[0227] In some embodiments, the first device may report the measured value of the measurement quantity to the network device, so that the network device can determine the channel quality between the first device and the A-IoT device or the A-IoT device group based on the measured value of the measurement quantity.

[0228] In some embodiments, when an A-IoT device transmits an uplink UR signal based on backscatter, the power of the UR signal transmitted uplink by the A-IoT device is related to the power of the CW signal. In this case, the measured value can also reflect the CW transmission quality, that is, the measured value can reflect both the uplink and downlink performance of the A-IoT device. For example, if the A-IoT device successfully reflects the uplink UR signal, it can be determined that the A-IoT device has received the downlink DT signal, and the uplink channel is less problematic.

[0229] In some embodiments, this step is optional, and the first device may not report the measured value of the measured quantity to the network device. In this case, the first device can act as a network device, that is, the first device can autonomously determine the channel quality between the first device and the A-IoT device or the A-IoT device group.

[0230] In the above embodiment, when the first device can serve as the second device, the third device and the network device, in other words, when the first device has all the capabilities of the second device, the third device and the network device, such as functions such as transmitting ES, DW and / or DT, the first device can adjust the parameters of ES, DW and / or DT according to the measurement values ​​of RRM.

[0231] The positioning measurement method involved in the embodiment of the present disclosure may include at least one of steps 2101 to 2109.

[0356] The following is an exemplary introduction to the above method.

[0357] The method shown in the embodiment of the present disclosure relates to a RRM method applicable to A-IoT devices.

[0358] A key application of A-IoT technology is the inventory and monitoring of large quantities of items or materials. The number of A-IoT terminal devices is enormous. To reduce the complexity of A-IoT devices, they may only support simple transmission and reception operations. However, they may not support processing operations such as radio resource management (RRM) measurements. RRM-related measurements can include reference signal received power (RSRP), reference signal received quality (RSRQ), or received signal strength indicator (RSSI). Therefore, if A-IoT devices are unable to perform RRM-related measurements, measuring the channel status of A-IoT devices in the network is a challenge that needs to be addressed.

[0359] 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.

[0360] 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.

[0361] 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.

[0362] 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.

[0363] 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.

[0364] 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.

[0365] In order to measure the channel status of the A-IoT device and perform wireless resource management, this example proposes that the first device transmits an excitation signal to the A-IoT device, the second device receives the uplink signal transmitted by the A-IoT device based on backscattering, and performs RRM measurement on the A-IoT device based on the reflected uplink signal, and the measurement content includes RSRP, RSRQ, RSSI or SINR, etc. The above-mentioned RRM measurement may also refer to the bit error rate or block error rate of the A-IoT transmission calculated based on RSRP, RSRQ, RSSI or SINR, etc. The RRM measurement value is directly related to the reception performance of the uplink signal of the A-IoT device, indicating whether the excitation signal can support the A-IoT device for uplink transmission, and because the A-IoT device can perform backscattering of the excitation signal, which means that the reception strength of the excitation signal exceeds a certain threshold, the RRM measurement value can simultaneously indicate the performance of the uplink and downlink transmission of the A-IoT network device.

[0366] The following two examples illustrate the RRM measurement method.

[0367] Example 1

[0368] This method can allocate corresponding time-frequency domain resources specifically for RRM measurement. The time-frequency domain resources are used for RRM measurement of A-IoT devices. The specific flow chart of this method is shown in Figure 8.

[0369] Step 1: The network device determines the first, second, and third devices for measuring RRM information for the A-IoT device. After determining the first, second, and third devices, the network device can send control information for downlink transmission, stimulation, and uplink reception used for RRM measurement to the first, second, and third devices.

[0370] In some embodiments, the first device, the second device, and the third device can be used to transmit incentives, receive backscatter-based uplink transmissions from A-IoT devices, and transmit downlink information to the A-IoT devices, respectively. The control information for downlink transmission, incentives, and uplink reception can be specifically used to instruct RRM measurements on A-IoT devices, or can be used for other purposes.

[0371] In some embodiments, the first device, the second device, and the third device may be the same or different devices. The network device may be the first device, the second device, and the third device, or the network device may be different devices. The first device may be a single device, or the first device may include multiple devices that transmit excitations. The second device may be a single device, or the second device may include multiple devices that receive uplink transmissions based on backscatter from the A-IoT device. The third device may be a single device, or the third device may include multiple devices that simultaneously transmit downlink signals to the A-IoT device.

[0372] In some embodiments, the control information of the stimulus may be configured by the network device or may be dynamically indicated by the network device. The control information of the stimulus may include, but is not limited to, at least one of the following:

[0373] 1.CW time and frequency resources.

[0374] 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.

[0375] 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.

[0376] 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:

[0377] 1. UR time-frequency resources. For example, the backscatter channel of the A-IoT device can be one or more channels.

[0378] 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.

[0379] 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:

[0380] 1.DT’s time and frequency resources.

[0381] 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.

[0382] 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.

[0383] In some embodiments, the DT may include one or more of the following parameters for controlling uplink transmission of the A-IoT device.

[0384] 1. Indicate one, a group, or all A-IoT devices.

[0385] 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.

[0386] 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.

[0387] 4. The start time and / or length of the uplink signal transmitted by the A-IoT device based on backscatter.

[0388] 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.

[0389] 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.

[0390] Step 2: The third device sends downlink information to the A-IoT device, triggering uplink transmission of the A-IoT device. The downlink information includes but is not limited to one or more of the following information.

[0391] 1. Indicate one, a group, or all A-IoT devices.

[0392] 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 gain factor of the reflection amplifier for type B A-IoT devices. Alternatively, the A-IoT device can operate at maximum backscatter power. Specifically, for type B A-IoT devices, this information can instruct the A-IoT device to disable the reflection amplifier or set the gain factor of the A-IoT device to 1.

[0393] 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.

[0394] 4. The start time and / or length of the uplink signal transmitted by the A-IoT device based on backscatter.

[0395] 5. Uplink information transmitted by the A-IoT device based on backscatter. This 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 and the sequence is the same for a group of A-IoT devices. The sequence can be specifically used to discover or adjust devices that support ES, DT, CW, or UR functions.

[0396] Step 3: The first device may set the transmission power and beam of the CW according to the received downlink information, and transmit the CW on the indicated time-frequency resources.

[0397] Step 4: The A-IoT device performs uplink transmission based on backscatter. 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 the uplink information.

[0398] Step 5: The second device receives the uplink signal transmitted by the A-IoT device based on backscatter, performs RRM measurements on the uplink signal, and obtains RRM measurement information about the A-IoT device, which it reports to the network. The second device can also directly process the RRM measurement values. For example, if the second device also transmits functions such as ES, DW, and / or DT, the second device can adjust the ES, DW, and / or DT parameters based on the RRM measurement values.

[0399] In the solution proposed in Example 1, when only one A-IoT device is instructed to reflect a CW, the measured RRM information indicates the channel status of that single A-IoT device. When only a group or all A-IoT devices are instructed to reflect a CW, the measured RRM information indicates the combined channel status of the group or all A-IoT devices. While this combined channel status doesn't reflect the precise channel status of each A-IoT device, it helps quickly detect whether a large number of A-IoT devices are within coverage.

[0400] Example 2

[0401] This method does not require the allocation of corresponding time-frequency domain resources for RRM measurement. The specific flow chart of this method is shown in FIG9 .

[0402] This method can perform RRM measurements on A-IoT devices while they are transmitting uplink information based on backscatter. This method also requires a first device, a second device, and a third device. The first device, second device, and third device are respectively used to transmit CWs, receive URs from A-IoT devices based on backscatter, and transmit downlink information to the A-IoT devices.

[0403] In some embodiments, the first device, the second device, and the third device may be the same or 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. The second device may be a receiving device that receives uplink information from A-IoT devices, or may be a device dedicated to RRM measurements.

[0404] Step 1: The third device sets the DT's transmission power and beam, and sends downlink information to the A-IoT device on the DT's time-frequency resources, triggering the A-IoT device's uplink transmission. The downlink information can also be used to control the A-IoT device's uplink transmission reception performance. The downlink information includes, but is not limited to, one or more of the following information:

[0405] 1. Indicate one, a group, or all A-IoT devices.

[0406] 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 gain factor of the reflection amplifier for Type B A-IoT devices. Alternatively, the A-IoT device can operate at maximum backscatter power. Specifically, for Type B A-IoT devices, this information can instruct the A-IoT device to disable the reflection amplifier or set the gain factor to 1.

[0407] 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.

[0408] 4. The start time and / or length of the uplink signal transmitted by the A-IoT device based on backscatter.

[0409] 5. Uplink information transmitted by the A-IoT device based on backscatter. The uplink information can be a unique identifier of the A-IoT device, a group identifier of the A-IoT device, or a configured or dynamically indicated sequence. The sequence can also be predefined. The sequence of different A-IoT devices can be different, or the sequence 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.

[0410] Step 2: The first device sets the transmission power and beam of the CW and transmits the CW on the CW time-frequency resources.

[0411] Step 3: The A-IoT device performs uplink transmission based on backscatter. 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 the uplink information.

[0412] Step 4: The second device receives the uplink signal transmitted by the A-IoT device based on backscatter, performs RRM measurements on the uplink signal, and obtains RRM measurement information about the A-IoT device, which can be reported to the network. The second device can also directly process the RRM measurement value.

[0413] In the solution proposed in Example 2, when only one A-IoT device is instructed to reflect CW uplink transmission information, the measured RRM information indicates the channel status of a single A-IoT device. When only a group or all A-IoT devices are instructed to reflect CW uplink transmission information, the measured RRM information indicates the superimposed channel status of the group or all A-IoT devices. Although the superimposed channel status cannot reflect the precise channel status of each A-IoT device, it is helpful for quickly discovering whether there are a large number of A-IoT devices within the coverage area.

[0414] In summary, the above embodiments of the present solution trigger the uplink transmission of the A-IoT device through two methods, receive the uplink signal backscattered by the A-IoT device, and process the uplink signal, so as to realize the RRM measurement of the A-IoT device, indicate the performance of the uplink and downlink transmission of the A-IoT device, and facilitate better determination of the transmission quality of the A-IoT device.
