[0151] FIG1A is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure. As shown in FIG1A , the method provided in the embodiment of the present disclosure can be applied to a communication system 100, which may include a first device 101 and a second device 102. It should be noted that the communication system 100 may also include other devices, and the present disclosure does not limit the devices included in the communication system 100.

[0152] In some embodiments, the first device 101 includes, for example, a device in the field of the Internet of Things. Optionally, the first device 101 is an Ambient-IoT (Environmental Internet of Things) device. In some embodiments, the Ambient-IoT is a type of Internet of Things. In some embodiments, the complexity of the first device 101 is low. Optionally, the Ambient-IoT device may not be provided with a battery, and may be excited and powered by an electromagnetic signal received by the Ambient-IoT device. Optionally, the Ambient-IoT device may be provided with a battery with a small amount of electrical storage function, which does not need to be powered by a power supply, but obtains energy from the outside world. For example, energy is obtained by obtaining external electromagnetic waves, thermal energy, kinetic energy, etc.

[0153] In some embodiments, the Ambient-IoT devices are of different types, and different types have different power acquisition methods or storage capabilities. The following describes different types of Ambient-IoT devices:

[0154] Type 1: Device A: Incapable of independent signal generation or amplification. In one possible implementation, device A operates in a backscattering mode. In another possible implementation, device A has no energy storage capability, or, in other words, no battery.

[0155] The second type: Device B: has energy storage capabilities but cannot independently generate signals. For example, Device B uses backscattering. In addition, Device B can use the stored energy to amplify the reflected signal.

[0156] The third type: Device C: has energy storage capabilities and can independently generate signals. Optionally, Device C has an RF module that actively sends signals.

[0157] Of the three device types mentioned above, device C has the strongest capabilities and the highest terminal cost. Device C has the weakest capabilities and the lowest terminal cost. Furthermore, since devices A and B can only operate in backscatter mode and cannot actively transmit signals, their supported terminal coverage is smaller. However, the power consumption of device A / B in this mode is much lower than that of device C.

[0158] In some embodiments, the first device 101 communicates using backscatter communication technology, a key technology in the Internet of Things. Backscatter communication utilizes the principle of RF signal backscattering to create an extremely low-power modulation and transmission technology. In backscatter communication, a device receives an RF signal, and its internal circuitry modulates the incoming electromagnetic wave using methods such as load impedance modulation to transmit the information. The modulated electromagnetic wave carrying the information is then transmitted. Various methods can be used to modulate information, including ASK, FSK, and PSK.

[0159] Alternatively, for devices using backscattering, the general process is as follows: the network sends a downlink command to the device, which then responds to the network or performs the corresponding operation. However, while the device is transmitting data, it needs a CW node to provide electromagnetic waves for reflection.

[0160] In some embodiments, devices using backscattering require a continuous wave (CW) energy source (CW node) to provide electromagnetic waves for reflection while transmitting data. CW waves typically have a constant amplitude. The CW node can be a separate node or a base station or intermediate node (e.g., a UE) communicating with the device.

[0161] The frequency of the electromagnetic wave reflected by the device can be exactly the same as the CW frequency, or there can be some offset. The offset size depends on the hardware characteristics of the device. The offset can be a fixed value, or if the device hardware supports it, it can support multiple fixed values, or it can be a dynamically adjustable value.

[0162] For devices using backscattering, the general process is as follows: the network sends a downlink command to the device, which then responds to the network or performs the corresponding operation. However, while the device is transmitting data, it needs a CW node to provide electromagnetic waves for reflection.

[0163] In some embodiments, one possible approach to frequency resource utilization in ambient IoT is to divide the available spectrum into multiple subchannels. Each subchannel occupies a fixed bandwidth, and the subchannels are orthogonal in the frequency domain. A device can be instructed by the network to use one or more of these subchannels for data transmission, or it can select one or more subchannels for data transmission using an algorithm.

[0164] For devices using backscattering, their antennas operate over a wide bandwidth, such as tens of MHz. If a CW node transmits CWs at multiple frequencies within the device's operating bandwidth, the device will receive CWs at these frequencies and backscatter them. This means the device cannot reflect only the CWs for a specific subchannel.

[0165] In this sense, which uplink sub-channel the device can use for uplink transmission actually depends on the frequency and offset capabilities of the CW.

[0217] Step S2106: The first device receives the third information sent by the second device.

[0218] It should be noted that if the third information is not received within the second time period, the second information is resent. In the embodiment of the present disclosure, if the first device does not receive the third information within the second time period, it means that the second device has not fed back the third information, or an error occurred during the transmission of the third information.

[0228] It should be noted that the embodiments of the present disclosure involve a first time period and a third time period. In some embodiments, the transmission power of the first device in the third time period is greater than the transmission power in the first time period.

[0229] In some embodiments, the second device controls the transmission power of the CW node in the third time period to be greater than the transmission power in the first time period, thereby the transmission power of the first device performing backscattering in the second time period is higher than the transmission power in the first time period.

[0321] FIG6 is a flow chart of a connection method according to an embodiment of the present disclosure. As shown in FIG6 , the embodiment of the present disclosure relates to a connection method, and the method includes:

[0322] Step S6101: A network node sends first information / signal on one or more operating frequencies supported by the network node.

[0323] In some embodiments, the first information / signal is used for a device to access the network.

[0324] In some embodiments, the network node used for ambient IoT device access may be a base station / terminal / intermediate node, etc.

[0325] In some embodiments, the first information / signal may be:

[0326] (1) A reference signal containing a network node ID. For example, a signal consisting of a preamble and a network node ID

[0327] (2) A first instruction including a network node ID, wherein the first instruction is used to instruct a device that has not yet connected to the network to initiate an access process.

[0328] The network node ID here can be, for example, a cell ID, a UE ID, or an intermediate node ID. If it is sent by an intermediate node, it can include both the intermediate node ID and the cell ID, or it can include only the intermediate node ID or only the cell ID.

[0329] In some embodiments, multiple operating frequencies for ambient IoT may be defined in the protocol. Network nodes may support multiple of these operating frequencies defined in the protocol. However, due to low cost and complexity, devices may only support one or a few fixed operating frequencies. The operating frequencies supported by a device are determined at device production. The operating frequency determined at device production must be one of the multiple operating frequencies defined in the protocol for ambient IoT.

[0330] In some embodiments, at each operating frequency point, the network node periodically sends the first information / signal. The period may be defined by the protocol. The periods at different operating frequencies may be the same or different. Alternatively, the network node may flexibly adjust the period. For example, based on the load at the operating frequency point, when the workload is heavy, the network node may send the first information / signal at a sparse period, and when the workload is light, the network node may send the first information / signal at a dense period.

[0331] In step S6102, after receiving the first information / signal at a certain working frequency, the device sends a second signal to the network node in a first time period. The second signal is used to initiate network access.

[0332] In some embodiments, the second signal includes a Device ID.

[0333] In some embodiments, the second signal may also include device capability information. Of course, the base station may also obtain device capability information from the core network after receiving the device ID, including whether the device supports timing, energy storage capability, energy harvesting capability, etc.

[0334] In some embodiments, the second signal may be sent repeatedly to enhance coverage.

[0335] In some embodiments, the first time period may be defined by a protocol (eg, there is a fixed first time interval from the end moment of the first information / signal), and the transmission of the CW needs to be ensured within the first time period.

[0336] Step S6103: After receiving the second signal, the network node provides feedback to the device, where the feedback information carries information indicating the device ID.

[0337] In some embodiments, if a device receives feedback from the network corresponding to the device, it indicates that the device has accessed the cell. After the device accesses the cell, the base station can perform some cell-specific configuration for the device (such as a cell-specific UE ID, an ID related to the scheduling order, and dedicated periodic resources).

[0338] In some embodiments, if the device does not receive feedback within the specified time period, it may resend the second signal during a second time period. The second time period is also defined by the protocol (e.g., a fixed second time interval from the end of the first information / signal), and CW transmission must be guaranteed during the second time period.

[0339] In step S6104, the network node may also inform the core network that the device has joined or left the network.

[0340] It should be noted that there are many ways to enable a device to leave a cell.

[0341] (1) The network node proactively initiates the process of a device leaving the cell. For example, if the network node learns from the core network / operation center that a device is leaving or the network node wishes the device to leave the cell, the network node may send a third message to the device, notifying the device of its departure from the network. Correspondingly, the base station may also delete the device's related information.

[0342] (2) If the network node sends information to the device N times but receives no response, the network node determines that the device is no longer in the coverage area and considers that the device has left the cell. N can be a value defined by the protocol or configured by the network.

[0343] (3) If the device does not receive any information / signal from the cell within a certain period of time, such as the first information / message mentioned above, the device considers that it has left the cell.

[0344] (4) The device monitors the first information / signal of another cell and before accessing the other cell, the device sends a notification of leaving the cell to the original base station.

[0345] (5) After the device connects to a new network node, the new network node can report the device's access to the cell to the core network. The core network can then notify the original network node that the device has left. (This assumes that the Ambient IoT network is not continuous. After the device leaves the cell, it may take some time to connect to the new cell.)

[0346] In the embodiments of the present disclosure, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations of other embodiments.

All units or modules of the above devices can be realized in the form of software called by the processor, or in the form of hardware circuits, or in part by the form of software called by the processor, and the rest by hardware circuits.

In addition, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), a tensor processing unit (TPU), a deep learning processing unit (DPU), etc.
