Description

Technical Field

[0001] The present application relates to the technical field of Internet of Things, and in particular to a communication method and storage medium of an Internet of Things system. Background Art

[0002] The main communication objects involved in the traditional 5G cellular network communication system include base stations (gNB) and user terminals (UE), while in passive IoT communication, three other communication objects are introduced: devices, readers, and carrier nodes. Among them, the reader sends an R2D (Reader-to-Device) signal to the device, and the device sends a D2R (Device-to-Reader) signal to the reader. Or after the reader sends an R2D signal to the device, the carrier node sends a carrier to the device, and the device uses the carrier sent from the carrier node to backscatter the carrier echo signal (D2R signal) to the reader. The device is a newly defined communication unit in passive IoT communication, and the reader and carrier node can be the base station and user terminal in the traditional 5G cellular network.

[0003] In the prior art, carrier nodes usually continuously send out carriers to ensure that the device can send D2R signals after acquiring the carrier. When the carrier node is not a base station, the disadvantage of the prior art is that the load of the carrier node increases and the efficiency decreases; and when there are multiple carrier nodes in the IoT system, and they all send out their own carriers, conflicts will occur between carriers and between carriers and other signals (D2R signals, R2D signals, and 5G signals transmitted between user terminals and base stations, etc.).

[0148] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0149] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the term "and / or" in this article is only a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article, unless otherwise specified, generally indicates that the associated objects before and after are in an "or" relationship.

[0150] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0151] In recent years, with the evolution of Internet of Things (IoT) device communications in cellular network communication systems, access to more "devices" has become a new demand. In order to adapt to more application scenarios, new requirements include the compression of device size, the reduction of complexity, and the reduction of power consumption. However, there is a problem that a large number of IoT devices cannot be effectively managed and it is difficult to effectively supply electricity. 3GPP (3rd Generation Partnership Project) has proposed a new AIoT (Ambient IoT) technology. AIoT is called passive IoT. Compared with existing IoT technologies, it can achieve more device connections and provide lower complexity and low power consumption than current low-power communication technologies (such as narrowband IoT NB-IoT and machine type communication eMTC). For Release 19 version of AIoT communication technology, 3GPP's RAN1 working group is currently mainly studying the characteristics of three types of AIoT devices, as shown in Table 1:

[0152] Table 1

[0153]

[0154] The main communication objects involved in the traditional 5G cellular network communication system include base stations (gNB) and user terminals (UE), while AIoT communication introduces three other communication objects:

[0155] Device: Device refers to AIoT devices. The devices in this application refer to two types of AIoT devices: Device 1 and / or Device 2a.

[0156] Reader: The reader is used to receive D2R signals sent by the device, and the reader can also send R2D signals to the device. The reader can be a base station or a user terminal. Therefore, when the reader is a base station, it can receive D2R signals sent by the device and communicate with other user terminals; when the reader is a user terminal, it can receive D2R signals sent by the device and communicate with other base stations and other user terminals.

[0157] Carrier Wave Node (CWN): The carrier wave node sends a carrier wave to the device. After the device obtains the carrier wave from the carrier wave node, it backscatters the carrier wave echo signal to the reader. The carrier wave echo signal is the D2R signal. The carrier wave node can be a base station or a user terminal.

[0158] It should be pointed out that since the readers and carrier nodes mentioned above can be base stations or user terminals, readers and carrier nodes can be integrated with existing entities in the IoT system. For example, an IoT system contains three entities: base stations, terminals (built-in readers and carrier nodes), and devices. Alternatively, readers and carrier nodes can be independent entities. For example, an IoT system contains five entities: base stations, user terminals, devices, readers, and carrier nodes.

[0159] The RAN1 working group of 3GPP defines the communication messages between readers and devices. Specifically, the message sent by the reader to the device is called the R2D (Reader-to-Device) signal, and the physical channel used is the PRDCH (Physical Reader-to-Device Channel); the signal sent by the device to the reader is called the D2R (Device-to-Reader) signal, and the physical channel used is the PDRCH (Physical Device-to-Reader Channel). After the reader sends the R2D signal to the device, the device obtains the carrier sent by the carrier node and sends the D2R signal to the reader through backscattering. The carrier can be a single-tone sinusoidal signal.

[0160] When the carrier node is not a base station, it is necessary to define when and how the carrier node sends the carrier. The existing technology is that the carrier node continuously sends the carrier to the outside to ensure that the device can respond to the corresponding R2D signal after obtaining the carrier, that is, send the D2R signal. The disadvantage of the existing technology is that the load of the carrier node becomes larger and the efficiency is reduced; and when there are multiple carrier nodes in the Internet of Things system, and they all send their own carriers to the outside, it will also cause conflicts and mutual influence between the carriers, and between the carriers and other signals (D2R signals, R2D signals, and 5G signals transmitted between user terminals and base stations, etc.). Therefore, when the carrier node is not a base station, it is necessary to manage the behavior of the carrier node sending the carrier.

[0161] This application proposes a communication method for an Internet of Things system, see Figure 1 As shown, the method is applied to a first Internet of Things system, which includes: a carrier node, a device, a reader, and a control base station; the reader is a user terminal; the control base station is used to manage the process of the carrier node sending the target carrier; the method includes:

[0162] S10: The carrier node sends carrier node attribute information to the control base station.

[0163] In some embodiments, the carrier node attribute information may include: whether the carrier node participates in external communication, and external communication refers to NR (New Radio) communication with other base stations and other user terminals. In the case where the carrier node does not participate in external communication, it is considered that the carrier node can always send the target carrier to the outside; at this time, there is no need to distinguish whether the carrier node is a user terminal or a base station. In the case where the carrier node participates in external communication, it is considered that the carrier node cannot always send the target carrier to the outside; at this time, it is necessary to further distinguish whether the carrier node is a user terminal or a base station, so as to adopt different methods to manage the carrier node.

[0164] In some embodiments, the carrier node attribute information may further include: the type of the carrier node, and the type of the carrier node includes: a base station and a user terminal.

[0165] S11: The control base station receives the carrier node attribute information, and compares the carrier node attribute information with a plurality of preset results, wherein the plurality of preset results include a first result, a second result, and a third result; when the carrier node attribute information is equal to the first result, first carrier parameter configuration information is sent to the reader and the carrier node respectively; wherein the first carrier parameter configuration information includes: target carrier power and target carrier frequency.

[0166] In some embodiments, the first result includes: the carrier node does not participate in external communication; the second result includes: the carrier node participates in external communication and the type of the carrier node is a user terminal; the third result includes: the carrier node participates in external communication and the type of the carrier node is a base station.

[0167] When the carrier node attribute information satisfies the condition that "the carrier node does not participate in external communication", the control base station sends the first carrier parameter configuration information to the reader and the carrier node respectively. If the carrier node is a base station, the control base station sends the first carrier parameter configuration information to the carrier node through the X2 interface. If the carrier node is a user terminal, the control base station sends the first carrier parameter configuration information to the carrier node through RRC signaling (Radio Resource Control).

[0168] S12: The carrier node receives and uses the first carrier parameter configuration information to generate and send a target carrier.

Therefore, after acquiring the first carrier parameter configuration information, the reader can use the R2D signal to send the first carrier parameter configuration information to the device.

[0174] In some embodiments, the target information includes a device ID. The device will receive multiple carriers of different powers and frequencies at the same time. The power amplitude of the carrier (e.g., the maximum power value) can be determined by detecting the envelope amplitude of the carrier, that is, detecting the peaks and troughs of the carrier. Therefore, after receiving the first carrier parameter configuration information (target carrier power, target carrier frequency), the device can filter out the target carrier from multiple carriers and receive the target carrier by detecting whether the envelope amplitude meets the characteristics of the target carrier power and / or whether the frequency is equal to the target carrier frequency; backscatter the target carrier to obtain the echo of the target carrier, load the target information onto the echo of the target carrier to obtain the target signal, which is the D2R signal, and send the target signal to the reader.

[0293] In some embodiments, the integrated user terminal determines whether to send the target carrier within the activation validity period. If necessary, the target carrier is generated and sent using the first carrier parameter configuration information.

[0294] In some embodiments, if the integrated user terminal first determines that the target carrier does not need to be sent within the activation validity period, after waiting for a certain period of time, the integrated user terminal again determines whether the target carrier needs to be sent within the activation validity period.

The carrier transmission request is recorded as CWTR (Carrier Wave Transmission Request). Using uplink communication resources can ensure that the integrated user terminal periodically sends CWTR to the control base station.

[0326] S117: The integrated user terminal receives and processes the target signal.

[0327] Based on the above embodiment, the timing of sending the target carrier is determined by the integrated user terminal. When the integrated user terminal has the need to send the target carrier, it can independently send the target carrier instead of sending the CWTR to the control base station.
