Description

[0003] In new radio (NR) systems, if a terminal device lacks prior information, it can perform a blind search across the entire network based on its supported operating frequency bands and the synchronization signal (SS) / physical broadcast channel (PBCH) block (SSB) specified by the protocol. After finding a frequency band with strong signal energy, it performs downlink synchronization and then receives system messages from network devices to obtain necessary configuration information.

[0082] To facilitate a clear description of the technical solutions of the embodiments of the present application, some of the terms and technologies involved in the embodiments of the present application are briefly introduced below:

[0083] 1. AIoT

[0084] AIoT aims to provide a low-power, low-complexity, and low-cost IoT solution. Within the Third Generation Partnership Project (3GPP) standards framework, it is a lower-capability standard than narrowband IoT (NB-IoT). Within non-3GPP frameworks, it targets the radio frequency identification (RFID) market, offering comparable yet superior technical solutions.

[0085] The demand for AIoT is to address scenarios not covered by current 3GPP technologies, such as the following three scenarios:

[0086] 1) Extreme environmental conditions, such as high pressure, extremely high / low temperature, and humid environment;

[0087] 2) Strong demands for one or more of ultra-low complexity, very small device size / form factor (e.g., millimeter thickness), maintenance-free (e.g., no need for traditional battery replacement of the device), and longer life cycle;

[0088] 3) Device scenarios where traditional battery drive is not suitable.

[0089] AIoT is also an IoT service that aims to provide AIoT devices with features such as low power consumption and low complexity, very small size, and a longer lifecycle. AIoT devices are powered by energy harvesting and can be battery-free or have limited energy storage capabilities (i.e., using capacitors). They can communicate with other devices without traditional power supplies and / or avoid human intervention for charging or replacement.

[0090] Typically, IoT devices that support ambient power do not have traditional batteries. Instead, the devices themselves use energy harvested from radio waves or any other form of energy available in the specific use case. For example, in some scenarios, AIoT devices can harvest energy from radio waves, which may originate from the 5G NR network entity or the terminal device. In other scenarios, IoT devices that support ambient power can harvest energy from solar energy, light, motion / vibration, heat, pressure, or any other source of energy.

[0091] AIoT devices can be divided into the following three types:

[0092] Type 1: This type of AIoT device has no energy storage capability, no independent signal generation / amplification, and can use backscatter transmission;

[0093] Type 2: This type of AIoT device has energy storage capabilities, does not generate independent signals, and can participate in backscatter transmission. The stored energy can be used to amplify the backscatter signal.

[0094] Type 3: This type of AIoT device has energy storage capabilities and generates independent signals.

[0095] 2. Inventory

[0096] Inventory management refers to the process by which a second device identifies a first device and obtains its identity (ID). This process can be applied in a variety of scenarios, such as logistics management or warehouse management. It can be particularly effective in scenarios with a large number of devices, saving significant manpower and resources while enabling quick and accurate inventory counts.

[0097] 3. RFID technology

[0098] RFID technology is a contactless automatic identification technology that enables contactless two-way data communication between network devices and terminal devices through wireless radio frequency. Network devices (such as readers) can use wireless radio frequency to read and write terminal devices (such as tags), thereby achieving the purpose of target identification and data exchange.

[0099] 4. Other terms

[0100] In the embodiments of the present application, terms such as "first" and "second" are used to distinguish between identical or similar items with substantially the same functions and effects. For example, the first information and the second information are merely used to distinguish different information and do not limit their order. Those skilled in the art will understand that terms such as "first" and "second" do not limit the quantity or execution order, and that terms such as "first" and "second" do not necessarily define differences.

[0101] It should be noted that in the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this application as "exemplary" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0102] In the embodiments of the present application, "at least one" refers to one or more, and "more" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: the existence of A alone, the existence of A and B at the same time, and the existence of B alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following items" or similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b, or c can represent: a, b, c, ab, ac, bc, or abc, where a, b, c can be single or multiple.

[0103] In order to better understand the communication method provided in the embodiment of the present application, the communication system architecture of the embodiment of the present application is first described below.

The tag may be an electronic tag, a smart tag, a radio frequency tag, a transponder or a data carrier, etc., and is usually composed of a coupling element and a chip. Each tag may have a unique electronic code. In some scenarios, the tag can be attached to an object to identify the object. The terminal may be a user equipment (UE), wherein the UE includes a handheld device, a vehicle-mounted device, a wearable device or a computing device with wireless communication capabilities. Exemplarily, the UE may be a mobile phone, a tablet computer or a computer with wireless transceiver capabilities. The terminal device may also be a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in unmanned driving, a wireless terminal in telemedicine, a wireless terminal in a smart grid, a wireless terminal in a smart city, a wireless terminal in a smart home, etc. In the embodiment of the present application, the device for realizing the function of the terminal may be a terminal; it may also be a device that can support the terminal to realize the function, such as a chip system, which may be installed in the terminal.

[0107] The second device involved in the embodiments of the present application can be a reader, a readout device, a scanner, a reader, a communicator, or a reader / writer, or the second device can also be an access network (RAN) device in a mobile communication system, which is mainly responsible for wireless resource management, QoS management, data compression and encryption on the air interface side. For example: a base station NodeB, an evolved base station eNodeB, a base station in a 5G mobile communication system or a new generation wireless (NR) communication system, a base station in a future mobile communication system, a macro base station, a micro base station, a pico base station, and a femto base station, etc.; or the second device can also be an intermediate node, which is located between the first device and the access network device, and the intermediate node can be a relay, an integrated access and backhaul (IAB) node, a UE, a repeater, etc.

[0108] Based on the communication system architecture shown in Figure 1A, an embodiment of the present application provides another communication system architecture diagram, as shown in Figure 1B. The communication system includes a base station and an AIoT device. The base station can provide energy to the AIoT device and wake up the AIoT device by sending an excitation signal; the AIoT device after energy storage can receive subsequent messages sent by the base station, and can also send messages to the base station.

[0109] It should be noted that the number of first devices (such as AIoT devices) in the above communication system architecture is only an example. The number of first devices can also be other values. This application does not limit the number of first devices in the communication system.

[0110] The technical solutions provided in the embodiments of the present application can be applied to the long term evolution (LTE) architecture, and can also be applied to the universal mobile telecommunications system (UMTS) terrestrial radio access network (UTRAN) architecture, or the global system for mobile communication (GSM) / enhanced data rate for GSM evolution (EDGE) system radio access network (GSM EDGE radio access network, GERAN) architecture. In addition, the technical solutions provided in the embodiments of the present application can also be applied to any other wireless communication system with similar structure and function, such as a public land mobile network (PLMN) system, a 5G communication system or a communication system after 5G, etc., and the embodiments of the present application do not impose any restrictions on this.

[0111] Wireless communication between communication devices may include: wireless communication between network devices and terminal devices, wireless communication between network devices and network devices, and wireless communication between terminal devices. In the embodiments of the present application, the term "wireless communication" may also be referred to as "communication", and the term "communication" may also be described as "data transmission", "information transmission" or "transmission". Those skilled in the art may apply the technical solutions provided in the embodiments of the present application to wireless communication between network devices and terminal devices, such as wireless communication between access network devices and terminal devices.

[0112] In related technologies, for devices with weaker capabilities, such as AIoT devices, they may only support one or a limited number of frequency bands and find it difficult to monitor multiple frequency bands at the same time, which will make it difficult for the devices to obtain messages sent by other devices.

[0113] To address the above technical issues, embodiments of the present application provide a communication method. The main inventive concept is as follows: A first device can communicate with a second device by receiving a first message and a second message sent by a second device, or by receiving a second message sent by the second device based on the second message. That is, based on the first message and / or the second message, the first device can correctly receive other messages sent by the second device.

[0114] The technical solutions shown in this application are described in detail below through specific embodiments. It should be noted that the following embodiments can exist independently or in combination with each other. For the same or similar content, such as the explanation of terms or nouns, and the explanation of steps, etc., different embodiments can refer to each other and will not be repeated.

[0116] S201. A second device sends a first message to a first device, where the first message is used to motivate the first device.

[0118] The second device may send the first message by broadcasting.

[0119] The first message may be referred to as a motivational message.

[0120] The first device can store energy by receiving the first message.

[0121] Stimulating the first device is equivalent to waking up the first device, that is, the first message can provide energy for the first device to wake up the first device, so that the first device can subsequently receive a message sent by the second device or send a message to the second device.

[0122] The first message may be carried in downlink control information (DCI), a media access control (MAC) control element (CE), or a master information block (MIB).

[0134] The indication information may be an information element (IE) in a system message.

[0135] Illustratively, the indication information may be initialinventory ENUMERATED{true,false}, or initialinventory ENUMERATED{true}, or initialinventory ENUMERATED{1,0}, or initialinventory ENUMERATED{0} in a system message.

[0139] The type of the third message may be inventory signaling, positioning signaling, sensor-related signaling, or command signaling.

[0140] Among them, positioning signaling is used to indicate location information reporting, positioning service-related signaling and ranging; sensor-related signaling can be used to indicate sensor-related reporting and / or sensor-related parameter modification; command signaling can be used to command device activation or deactivation, or command adjustment of asset status.

[0141] The RNTI associated with the third message can be used to scramble the third message. If the third message is configured for a first device, only the first device can decrypt the third message using the RNTI. If the third message is broadcast, any first device receiving the third message can decrypt the third message using the RNTI.

[0142] In a possible implementation, the third message may be used to motivate the first device and / or for synchronization.

[0143] When the third message is used to provide energy to the first device, the third message may be referred to as an incentive message.

[0144] The third message is used for synchronization, which may refer to determining the time domain reception position of subsequent messages with the reception time of the third message as the starting point and a predefined or configured time length as the interval.

[0145] The unit of duration can be expressed in frames, subframes, absolute time or timer.

[0146] The unit of duration can be predefined.

[0147] In a possible implementation, the third message may be used to instruct the first device to perform an inventory.

[0148] In this implementation, the third message may be a control signaling. For example, the third message may be called an inventory signaling.

[0149] 3) Frequency domain related information supported by the second device.

[0150] The frequency domain related information supported by the second device may also be referred to as the AIoT frequency domain related information supported by the second device.

[0151] In a possible implementation, the frequency domain related information supported by the second device may include a frequency range supported by the second device or a recommended frequency list.

[0152] The recommended frequency list may include multiple recommended frequencies. The frequencies in the recommended frequency list are also frequencies supported by the second device.

[0153] Multiple frequencies in the recommended frequency list may be arranged according to priority.

[0154] For example, as shown in Table 1, multiple frequencies in the recommended frequency list can be arranged in order of priority, that is, the priority of frequency 1 is higher than the priority of frequency 2, the priority of frequency 2 is higher than the priority of frequency 3, the priority of frequency 3 is higher than the priority of frequency 4, the priority of frequency 4 is higher than the priority of frequency 5, and the priority of frequency 5 is higher than the priority of frequency 6.

[0155] Table 1

[0156] As another example, as shown in Table 2, multiple frequencies in the recommended frequency list can be arranged in order of priority, that is, the priority of frequency 6 is lower than the priority of frequency 5, the priority of frequency 5 is lower than the priority of frequency 4, the priority of frequency 4 is lower than the priority of frequency 3, the priority of frequency 3 is lower than the priority of frequency 2, and the priority of frequency 2 is lower than the priority of frequency 1.

[0157] Table 2

[0158] It should be noted that the frequency recommendation list is only one form of expression of the frequencies recommended by the second device, and this application does not limit the form of expression of the frequencies recommended by the second device. For example, the frequencies recommended by the second device can also be expressed in the form of a data set. Specifically, the frequency recommendation list in Table 1 can also be expressed in the form of {frequency 1, frequency 2, frequency 3, frequency 4, frequency 5, frequency 6}, and the frequency recommendation list in Table 2 can also be expressed in the form of {frequency 6, frequency 5, frequency 4, frequency 3, frequency 2, frequency 1}.

[0159] In one possible implementation, the frequency-related information may directly include the specific frequency recommended by the second device (ie, a specific frequency list), and may also include an index corresponding to the frequency recommended by the second device. The first device may determine the specific frequency based on the index.

[0160] In a possible implementation, when the frequency-related information only includes a frequency range supported by the second device, the frequencies in the frequency range supported by the second device may be arranged according to priority.

[0161] Illustratively, the frequencies in the frequency range supported by the second device may be arranged in order of priority, that is, the frequency with the highest priority is arranged first, and the frequency with the lowest priority is arranged last.

[0162] As another example, the frequencies in the frequency range supported by the second device may be arranged in order of priority, that is, the frequency with the lowest priority is arranged first, and the frequency with the highest priority is arranged last.

[0163] In this manner, the arrangement order of the frequencies in the frequency range supported by the second device implicitly indicates the priority of the frequencies.

[0164] In another possible implementation, when the frequency-related information includes not only the frequency range supported by the second device, the frequency-related information may also include the priority of each frequency in the frequency range supported by the second device, that is, in this way, the frequency-related information may directly indicate the priority of each frequency in the frequency range supported by the second device.

[0165] In this manner, the frequencies in the frequency range supported by the second device may be arranged according to priority or may not be arranged according to priority.

[0166] In a possible implementation, the priority of each frequency may be determined according to the congestion level of the frequency.

[0167] In a possible implementation, the frequency-related information may directly include a specific frequency range supported by the second device, and may also include an index corresponding to the frequency range supported by the second device. The first device may determine the specific frequency range according to the index.

[0168] 4) Community related information

[0169] In a possible implementation, the cell-related information may include a period of the second message and / or cell access indication information, wherein the cell access indication information indicates whether the cell prohibits the first device from accessing.

[0170] In a possible implementation manner, the cell-related information may further include at least one of the following: a cell index, a public land mobile network (PLMN) index list, a tracking area code, or an area code list.

[0171] In a possible implementation, the second message may also be used to motivate the first device.

[0172] S203. The first device communicates with the second device based on the second message.

[0173] Exemplarily, the first device may communicate with the second device in the following ways:

[0174] (1) The second message includes indication information

[0175] The first device may send a confirmation message to the second device based on the indication information, and the confirmation message may include a related identifier of the first device.

[0176] The relevant identifier of the first device may be RN16, electronic product code (EPC), UE identification (dentification, ID), cell-radio network temporary identifier (c-RNTI), international mobile subscriber identity (IMSI), etc.

[0177] In a possible implementation, the first device may send a confirmation message to the second device at the first moment.

[0178] The duration between the first moment and the moment of receiving the second message is less than or equal to the first duration, and the first duration is predefined or carried by the indication information.

[0179] For example, as shown in FIG3A , the second device may first send a first message to the first device to stimulate the first device; then the second device sends a second message to the first device, and the second message carries indication information, instructing the first device that initially enters the cell coverage to take an inventory; after receiving the second message, the first device sends a confirmation message to the second device at a first moment, and the confirmation message includes the relevant identifier of the first device, and the duration T1 between the first moment and the moment of receiving the second message is less than or equal to the first duration.

[0180] The second device can determine the first devices already in its coverage based on the received confirmation information, so as to accurately manage the first devices in its coverage.

[0181] (2) The second message includes the configuration information of the third message

[0182] The first device may determine a receiving location of the third message based on the configuration information of the third message, and receive the third message at the receiving location.

[0183] For example, as shown in Figure 3B, taking the third message as the incentive message, the second device can first send a first message to the first device to motivate the first device; then the second device sends a second message to the first device, and the second message carries the configuration information of the third message; after receiving the second message, the first device takes the receiving time of the second message as the starting point, and uses the predefined duration T2 or the duration carried in the configuration information as the interval to determine the receiving position of the incentive message, and receives the incentive message at the receiving position of the incentive message.

[0184] As another example, as shown in Figure 3C, taking the third message as inventory signaling as an example, the second device can first send a first message to the first device to stimulate the first device; then the second device sends a second message to the first device, and the second message carries the configuration information of the third message; after receiving the second message, the first device receives the inventory signaling based on the time domain position in the configuration information of the third message, and the inventory signaling may include the device type or device ID required for inventory; when the inventory signaling includes the device type required for inventory, the first device can send RN16 to the second device if the type of the first device receiving the inventory signaling belongs to the device type required for inventory; when the inventory signaling includes the device ID, the first device can send RN16 to the second device only if the ID of the first device receiving the inventory signaling is the same as the device ID.

[0185] How the first device receives subsequent signaling is determined through the mapping relationship from the first message to the second message to the third message.

[0186] (3) The second message includes the instruction information and the configuration information of the third message

[0187] For example, as shown in Figure 3D, taking the third message as the incentive message, the second device can first send a first message to the first device to encourage the first device; then the second device sends a second message to the first device, and the second message carries indication information and configuration information of the third message, and the indication information indicates to reply to the confirmation message within the first time length; after receiving the second message, the first device takes the receiving time of the second message as the starting point, and the time length T2 predefined or carried in the configuration information as the interval to determine the receiving position of the incentive message, and receives the incentive message at the receiving position of the incentive message; after receiving the incentive message, the first device can send a confirmation message to the second device, and the confirmation message includes the relevant identification of the first device, and the time length T1 between the sending time of the confirmation message and the receiving time of the second message is less than or equal to the first time length.

[0188] (4) The second message includes information related to the frequencies supported by the second device

[0189] The first device can determine a first frequency based on frequency-related information supported by the second device, where the first frequency is a frequency in a frequency range supported by the second device, or the first frequency is a frequency in a recommended frequency list; the first device can receive or send messages on the first frequency.

[0190] Exemplarily, when the frequency-related information includes a frequency range supported by the second device, the first frequency may be the frequency with the highest priority in the frequency range supported by the second device; when the frequency-related information includes a recommended frequency list, the first frequency may be the frequency with the highest priority in the recommended frequency list.

[0191] (5) The second message includes indication information and frequency related information supported by the second device

[0198] When the cell-related information includes a period of the second message, after receiving the second message, the first device determines a receiving position for a subsequent second message based on the period of the second message, and receives the subsequent second message at the receiving position for the subsequent second message.

[0199] When the cell-related information includes cell access indication information, if the cell access indication information indicates that the cell prohibits the first device from accessing, the first device can select other cells for communication; if the cell access indication information indicates that the cell allows the first device to access, the first device can select the cell for communication.

[0200] When the cell-related information includes the period of the second message and the cell access indication information, after the first device receives the second message, if the cell access indication information indicates that the cell allows the first device to access, the first device can determine the receiving position of the subsequent second message based on the period of the second message, and receive the subsequent second message at the receiving position of the subsequent second message.

[0205] (11) The second message includes frequency-related information and cell indication-related information supported by the second device

[0215] In the embodiment shown in FIG2 , the first device is stimulated by the first message so that the first device can receive a subsequent second message, and the first device can communicate with the second device through the second message.

[0216] FIG4 is a sixth flow chart of a communication method according to an embodiment of the present application. As shown in FIG4 , the communication method includes:

[0217] S401: A second device sends a first message to a first device, where the first message is used to stimulate the first device and for synchronization.

[0218] In other words, the first device receives the first message sent by the second device.

[0219] The second device may send the first message by broadcasting.

[0220] The first message may be referred to as a motivational message.

[0221] The first message may provide energy for the first device to stimulate (wake up) the first device, so that the first device can subsequently receive a message sent by the second device or send a message to the second device.

[0222] The first device can store energy by receiving the first message.

[0223] The use of the first message for synchronization may refer to determining the time domain reception position of the second message with the reception time of the first message as the starting point and with a predefined or configured time length as the interval.

[0224] The unit of duration can be expressed in frames, subframes, absolute time or timer.

[0225] The unit of duration can be predefined.

[0226] In one possible implementation, the first message may carry at least one second duration, at least one second duration corresponds one-to-one to at least one second message, and each second duration is the duration between the reception time of the corresponding second message and the reception time of the first message.

[0227] Multiple first messages may be used to indicate the time domain position of the same second message, one first message may be used to indicate the time domain position of the first second message, or one first message may be used to indicate the time domain positions of multiple second messages.

[0228] Exemplarily, the first message may use a predefined code to represent the size of the second duration carried by the first message.

[0229] In this embodiment, the first device may be a passive AIoT device.

[0230] S402: The second device sends a second message to the first device.

[0231] It should be noted that the execution process of S402 can refer to the execution process of S202, which will not be repeated here. The only thing that needs to be noted is that the time domain position of the second message can be determined based on the first message.

[0232] S403: The first device communicates with the second device based on the second message.

[0233] It should be noted that the execution process of S403 can refer to the execution process of S203, and will not be repeated here.

[0234] Based on the embodiment shown in FIG4 , the communication method of the present application will be described in detail below in conjunction with FIG5 .

[0235] FIG5 is a flow chart of the communication method provided in an embodiment of the present application. As shown in FIG5 , the communication method includes:

[0236] S501: A second device sends a first message to a first device, where the first message is used to stimulate the first device and for synchronization.

[0237] It should be noted that the execution process of S501 can refer to the execution process of S401 and will not be repeated here.

[0238] S502. The first device determines the time domain position of the second message based on the reception time of the first message and the second duration.

[0239] The second duration may be predefined or carried in the first message.

[0240] If multiple first messages are used to indicate the time domain position of the same second message, the time domain position of the second message may be determined by the following example.

[0241] For example, as shown in FIG6A , three first messages are used to indicate the time domain position of one second message. If the receiving time of the first first message is 0ms, the second time length it carries is 6ms; the receiving time of the second first message is 2ms, the second time length it carries is 4ms; the receiving time of the third first message is 4ms, and the second time length it carries is 2ms; then the time domain position of the second message can be determined to be 6ms through the three first messages.

[0242] If one first message is used to indicate the time domain positions of multiple second messages, the time domain positions of the second messages may be determined by the following example.

[0243] For example, as shown in Figure 6B, one first message is used to indicate the time domain positions of three second messages. If the first message carries three time lengths: 6ms, 12ms, and 18ms, and the receiving time of the first message is 0ms, it can be determined that the time domain position of the first second message is 6ms, the time domain position of the second second message is 12ms, and the time domain position of the third second message is 18ms.

[0244] S503: The second device sends a second message, and the first device receives the second message at a time domain location.

The first message also indicates the receiving location of the second message, allowing the first device to receive the second message at the correct location. The first device can then communicate with the second device through the second message. In other words, the mapping relationship from the first message to the second message to the subsequent messages allows the first device to correctly receive the message sent by the second device.

[0260] S803: The second device sends a second message, and the first device receives the second message at a time domain location.

[0261] S804: The first device communicates with the second device based on the second message.

[0262] It should be noted that the execution process of S802 to S804 can refer to the execution process of S502 to S504, and will not be repeated here.

[0263] In the embodiment shown in Figure 8, the first message can indicate the receiving location of the second message, allowing the first device to receive the second message at the correct location. The first device can then communicate with the second device through the second message. In other words, through the mapping relationship from the first message to the second message to subsequent messages, the first device can correctly receive the message sent by the second device.
