[0049] Figure 2 shows a block diagram of another wireless communication system applicable to embodiments of this application. The wireless communication system includes an AIoT device 21, a terminal 22, and a network-side device 23.

[0052] It should be noted that Figure 2 exemplarily illustrates a network-side device, a terminal, and an AIoT device. Optionally, the wireless communication system may include at least two network-side devices, and the coverage area of ​​each network-side device may include other numbers of terminals and AIoT devices. This application embodiment does not limit this.

[0053] To facilitate a better understanding of the embodiments of this application, relevant knowledge of AIoT will be explained.

[0054] Environmental IoT is an IoT business consisting of a massive number of devices. The AIoT devices that support this business are characterized by ultra-low complexity, ultra-low cost, and ultra-low power consumption. They can power themselves through energy harvesting and have no batteries or only limited energy storage capacity (e.g., using a capacitor).

[0055] In wireless communication systems, AIoT devices typically use energy harvested from radio waves, which may come from network devices (such as base stations) or UEs.

[0056] In some scenarios, AIoT devices can be devices with the following characteristics:

[0057] 1. Peak power consumption is approximately 1μW, and it has energy storage capabilities. This AIoT device does not have uplink or downlink signal amplification functions. The uplink transmission of this AIoT device is based on backscattering from an externally provided carrier source (such as the aforementioned radio waves).

[0058] 2. Peak power consumption is less than or equal to several hundred μW, and it has energy storage capabilities. This AIoT device supports uplink and / or downlink signal amplification functions. The uplink transmission of this AIoT device can be generated directly by the device itself, or it can be achieved through backscattering from an externally provided carrier source.

[0059] 3. Active device, which has energy storage, active radio frequency components for transmission, and is capable of generating signals independently.

[0060] Consider deploying AIoT devices using the following topology:

[0061] Topology 1:

[0062] Figure 3 is a schematic diagram of a deployment scenario for an AIoT device provided in an embodiment of this application. As shown in Figure 3, the AIoT base station (BS) and the base station of the communication system coexist at the same location. The base station acts as a carrier source, and the base station excites the AIoT device to perform backscattering, i.e., to transmit uplink data to the base station, through the downlink carrier.

[0063] Topology 2:

[0064] Figure 4A is a schematic diagram of another deployment scenario of AIoT device provided in an embodiment of this application. As shown in Figure 4A, the AIoT BS and the base station coexist at the same location, with the terminal acting as an intermediate node. The base station controls the terminal through air interface signaling, and the terminal excites the AIoT device to perform backscattering, i.e., uplink transmission to the terminal, through downlink carrier excitation. The terminal then forwards the uplink transmission of the AIoT device to the base station through the air interface.

[0065] Topology 3:

[0066] Figure 4B is a schematic diagram of another deployment scenario of an AIoT device provided in an embodiment of this application. As shown in Figure 4B, the terminal acts as a carrier source, and the terminal excites the AIoT device to perform backscattering through the downlink carrier, that is, to perform uplink transmission to the terminal.

[0067] The main business types of AIoT devices include: inventory, issuing commands, etc.

[0068] Inventory is the most basic and important business of AIoT. Inventory allows the network to know the coverage area of ​​a specific AIoT device's reader / registrant through the reader or register.

[0069] After an AIoT device is identified by the network, the AIoT server can issue commands to the device via the 3GPP network, specifically including:

[0070] Based on the aforementioned AIoT services, the possible data transmission models, or service types, or data types for AIoT devices may include:

[0071] Device-originated (DO) and device-terminated (DT) data are used to indicate that the data stream originates from or is transmitted to an AIoT device. For data streams originating from AIoT devices (DO data), further classification is possible: Device-originated-autonomous (DO-A) and Device-originated–device-terminated-triggered (DO-DTT) data, which is triggered by the network.

[0072] DO-A stands for Device Autonomous Data Transmission, which involves connecting a large number of various sensors that collect and proactively report information about the environment, the device, and the organisms when necessary.

[0073] DO-DTT means that data transmission is initiated by the device after being triggered by the network. Examples include asset identification, status reporting, and tracking. These are all downlink-triggered reports, and the reader collects data from the tag by triggering an inventory procedure. Since the data is generated / initiated within the AIoT device, this service should be considered as a DO service initiated by the tag after a command sent by the reader.

[0074] To facilitate a better understanding of the embodiments of this application, the problems solved and the solutions proposed in this application will be explained.

[0075] As mentioned above, how to configure resources for AIoT devices to enable communication between AIoT devices and environmental IoT readers is a technical problem that this application urgently needs to solve.

[0076] To address the aforementioned technical issues, embodiments of this application propose determining the environmental IoT transmission resource configuration for messages transmitted from the AIoT device to the environmental IoT reader based on the service characteristics of the target environmental IoT service associated with the AIoT device. The message is associated with the target environmental IoT service, and communication between the AIoT device and the environmental IoT reader is achieved based on the resource configuration.

[0077] The environmental IoT communication method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0078] Figure 5 is an interactive flowchart of an environmental IoT communication method provided in an embodiment of this application. This method can be executed by an environmental IoT device, i.e., an AIoT device, and an environmental IoT reader. The environmental IoT device can be AIoT device 11 in Figure 1, AIoT device 21 in Figure 2, or AIoT devices in Figures 3, 4A, and 4B, but is not limited to these. The environmental IoT reader can be an access network device included in network-side device 12 in Figure 1, an access network device included in network-side device 23 in Figure 2, a base station in Figure 3, or a terminal in Figures 4A and 4B, but is not limited to these. The environmental IoT reader can also be referred to as a backscattering device, etc., and this embodiment of the application does not limit this. As shown in Figure 5, the method may include:

[0079] S510: The environmental IoT reader sends a first message to the environmental IoT device; wherein, the first message includes: a first environmental IoT transmission resource configuration; the first environmental IoT transmission resource configuration is determined based on the service characteristics of the target environmental IoT service;

[0080] S520: The environmental IoT device sends a second message to the environmental IoT reader based on the first environmental IoT transmission resource configuration.

[0081] It should be understood that the target environment IoT business is any business associated with environmental IoT devices.

[0082] In some possible implementations, the business characteristics of the target environment IoT service include at least one of the following: business type; business cycle; expected latency of the business response message; expected size of the business response message; wherein, the business response message is the response message corresponding to the business request message used by the environment IoT server to request the target environment IoT service.

[0083] In some implementations, the business type is any of the following: DO-A type; DO-DTT type; DT type.

[0084] In some implementations, the business cycle refers to how often a target environment IoT business is performed. For example, the environment IoT server initiates a write operation every 30 seconds. The environment IoT device initiates a sensor data reporting operation every 10 seconds.

[0085] It should be understood that if the target environmental IoT service is of type DT or DO-DTT, then the target environmental IoT service can be a service initiated by the environmental IoT server. For example, the target environmental IoT service can be an inventory service or a command service (read service or write service) initiated by the environmental IoT server. In this case, the aforementioned first message can be obtained by the environmental IoT reader based on a service request message from the environmental IoT server, which is used to trigger the target environmental IoT service. Accordingly, the environmental IoT device can generate a response message to the first message, i.e., the second message, and send the second message to the environmental IoT reader. Further, the environmental IoT reader can generate a service response message based on the second message and send the service response message to the environmental IoT server.

[0086] In some implementations, the expected latency of the business response message can be the expected latency of the business response message reception time relative to the business request message sending time, but it is not limited to this.

[0087] In some implementations, the expected size of the service response message can be the expected number of bits contained in the service response message, but it is not limited to this. The expected size of the service response message can also be referred to as the expected length of the service response message, and this application embodiment does not impose any limitation on this.

[0088] In some implementations, if the target environment IoT service includes reading services, the first message includes the starting position of the data being read and the size of the data being read, and the second message includes the data being read from the environmental IoT device.

[0089] In some implementations, if the target environment IoT service includes write operations, the first message includes the written data, and the second message includes an acknowledgment (ACK) or a non-acknowledgment (NAK), where ACK indicates that the data was written successfully, and NAK indicates that the data was written unsuccessfully.

[0090] It should be understood that if the target environment IoT service is of type DO-A, it means that the service is initiated autonomously by the environmental IoT device. In this case, there may be no service response message. Based on this, the target environment IoT service may not include: the expected latency of the service response message; and the expected size of the service response message.

[0091] In other possible implementations, the business type of the target environment IoT business is any of the following: inventory, etc.

[0092] In some implementations, the first environmental IoT transmission resource configuration may refer to the environmental IoT transmission resource configuration of messages transmitted from the AIoT device to the environmental IoT reader, or the first environmental IoT transmission resource configuration may be used to transmit messages from the AIoT device to the environmental IoT reader. For example, the first environmental IoT transmission resource configuration may be used to transmit a second message.

[0093] In some possible implementations, the first environment IoT transmission resource configuration includes at least one of the following: time domain resource configuration; frequency domain resource configuration; code domain resource configuration.

[0094] In some implementations, the time-domain resource configuration included in the first environment IoT transmission resource configuration can be an absolute time-domain resource configuration, such as a protocol-predefined time-domain location indication, or a relative time-domain resource configuration, such as a time offset relative to the reception time of the first message.

[0095] In some implementations, the frequency domain resource configuration included in the first environment IoT transmission resource configuration can be an absolute frequency domain resource configuration, such as a frequency domain position indication predefined by the protocol, or a relative frequency domain resource configuration, such as a frequency domain offset relative to the receiving frequency position of the first message.

[0096] In some possible implementations, the code domain resource configuration included in the first environment IoT transmission resource configuration can be an absolute code domain resource configuration, such as a code domain position indication predefined by the protocol, or a relative code domain resource configuration, such as a code domain offset relative to the received codeword / text of the first message.

[0097] In some implementations, the environmental IoT reader is a terminal or an access network device. For example, in the wireless communication system shown in Figure 1 and the deployment scenario of the AIoT device shown in Figure 3, the environmental IoT reader is an access network device, such as a base station; in the wireless communication system shown in Figure 2 and the deployment scenarios of the AIoT devices shown in Figures 4A and 4B, the environmental IoT reader is a terminal. Based on this, in the wireless communication system shown in Figure 1 and the deployment scenario of the AIoT device shown in Figure 3, the access network device, such as a base station, can determine the first environmental IoT transmission resource configuration based on the service characteristics of the target environmental IoT service. In the wireless communication system shown in Figure 2 and the deployment scenario of the AIoT device shown in Figure 4A, the terminal or access network device can determine the first environmental IoT transmission resource configuration based on the service characteristics of the target environmental IoT service. In the deployment scenario of the AIoT device shown in Figure 4B, the terminal can determine the first environmental IoT transmission resource configuration based on the service characteristics of the target environmental IoT service. Whether the terminal or the access network device determines the first environmental IoT transmission resource configuration, it can use any of the following implementation methods, but is not limited to them:

[0098] In some possible implementations, it is assumed that the service characteristics of the target environment's IoT service include: the expected latency of the service response message. The smaller this expected latency, the smaller the time offset of the time-domain resource configuration included in the first environment's IoT transmission resource configuration relative to the reception time of the first message. Specifically, there is a mapping relationship between the expected latency of the service response message and the time offset of the time-domain resource configuration included in the first environment's IoT transmission resource configuration relative to the reception time of the first message.

[0099] In some possible implementations, it is assumed that the service characteristics of the target environment's IoT service include: the expected size of the service response message; the larger the expected size, the larger the resource size included in the first environment's IoT transmission resource configuration. Specifically, the expected size of the service response message is mapped to the time offset of the time-domain resource configuration included in the first environment's IoT transmission resource configuration relative to the reception time of the first message.

[0100] In some implementation methods, assuming the business characteristics of the target environment's IoT service include: business type, then the expected latency of the business response message corresponding to that business type can be determined. The smaller the expected latency, the smaller the time offset of the time-domain resource configuration included in the first environment's IoT transmission resource configuration relative to the reception time of the first message. There is a mapping relationship between the business type of the target environment's IoT service and the expected latency of the business response message.

[0101] In some implementation methods, assuming the business characteristics of the target environment's IoT services include: business type, then the expected size of the business response message corresponding to that business type can be determined. The larger the expected size, the larger the resource size included in the first environment's IoT transmission resource configuration. There is a mapping relationship between the business type of the target environment's IoT services and the expected size of the business response message.

[0102] In some implementation methods, assuming the business characteristics of the target environment's IoT service include a business cycle, the expected latency of the business response message corresponding to that business cycle can be determined. The smaller the expected latency, the smaller the time offset of the time-domain resource configuration included in the first environment's IoT transmission resource configuration relative to the reception time of the first message. There is a mapping relationship between the business cycle of the target environment's IoT service and the expected latency of the business response message.

[0103] In some possible implementations, assuming that the business characteristics of the target environment IoT service include at least two of the following: business type; business cycle; expected latency of the business response message; and expected size of the business response message, then the one with the highest priority among the at least two can be selected, and the time offset of the time domain resource configuration included in the first environment IoT transmission resource configuration relative to the reception time of the first message can be determined based on the one with the highest priority.

[0104] For example, suppose the business characteristics of the IoT service in the target environment include: the expected latency of the service response message and the expected size of the service response message. Suppose that the priority of the expected latency of the service response message is higher than the priority of the expected size of the service response message. Based on this, if the expected latency is larger, the time offset of the time domain resource configuration included in the IoT transmission resource configuration of the first environment relative to the reception time of the first message will be larger.

[0105] It should be understood that if the environmental IoT reader is a terminal, then the terminal has both an air interface with the access network device and an AIoT interface with the environmental IoT device. Based on this, when the environmental IoT reader is a terminal, the first environmental IoT transmission resource configuration can be determined by the terminal based on the service characteristics and the terminal's air interface resource configuration.

[0106] In some possible implementations, if the terminal's AIoT interface and air interface are allowed to work simultaneously, then the first environment IoT transmission resource configuration can be a common resource configuration based on the resource configuration determined by the business characteristics and the air interface resource configuration.

[0107] In some implementations, if the terminal's AIoT interface and air interface are not allowed to work simultaneously, and the resource configuration determined based on the service characteristics includes part or all of the terminal's air interface resource configuration, then the first environment IoT transmission resource configuration is the configuration other than the terminal's air interface resource configuration in the resource configuration determined based on the service characteristics.

[0108] In some implementations, if the terminal's AIoT interface and air interface are allowed to work simultaneously, and the resource configuration determined based on the service characteristics does not include the terminal's air interface resource configuration, then the first environment IoT transmission resource configuration is the resource configuration determined based on the service characteristics.

[0109] In some implementations, where the environmental IoT reader is a terminal, the first environmental IoT transmission resource configuration is determined by the access network device in response to a first environmental IoT resource configuration request from the terminal. This first environmental IoT resource configuration request includes the aforementioned service characteristics. The access network device may be the serving base station of the terminal.

[0110] It should be understood that the first environment IoT resource configuration request is used to request the configuration of the first environment IoT resources.

[0111] The following example illustrates the IoT communication method in the deployment scenario corresponding to Figure 3.

[0116] It should be understood that the explanation of the target environment IoT business and the business characteristics of the business can be found above, and will not be repeated in the embodiments of this application.

[0117] S620: The base station determines the configuration of IoT transmission resources in the first environment based on the service characteristics of IoT services in the target environment;

The specific form of the first environment IoT transmission resource configuration can also be an AIoT Radio Resource Control (RRC) SDU, such as an AIoT RRC message.

[0121] S640: The AIoT device sends a second message to the base station based on the configuration of IoT transmission resources in the first environment.

[0131] It should be understood that the explanation of the configuration of IoT transmission resources in the first environment can be found above, and will not be repeated in this application embodiment.

[0132] In some implementations, the terminal can determine the IoT transmission resource configuration of the first environment based on service characteristics and the terminal's air interface resource configuration.

[0133] In some implementations, if the terminal's AIoT interface and air interface are allowed to operate simultaneously, then the first-environment IoT transmission resource configuration can be a common resource configuration based on service characteristics and air interface resource configuration. For example, the first-environment IoT transmission resource configuration can be allocated within the uplink (UL) grant already obtained by the terminal.

[0134] In some implementations, if the terminal's AIoT interface and air interface are not allowed to operate simultaneously, and the resource configuration determined based on the service characteristics includes part or all of the terminal's air interface resource configuration, then the first environment IoT transmission resource configuration is the configuration other than the terminal's air interface resource configuration in the resource configuration determined based on the service characteristics. For example, the first environment IoT transmission resource configuration needs to avoid the downlink (DL) assignment already obtained by the terminal.

[0135] In some implementations, if the terminal's AIoT interface and air interface are allowed to work simultaneously, and the resource configuration determined based on the service characteristics does not include the terminal's air interface resource configuration, then the first environment IoT transmission resource configuration is the resource configuration determined based on the service characteristics.

[0136] S740: The terminal sends a first message to the AIoT device; wherein, the first message includes: first environment IoT transmission resource configuration;

[0137] In some possible implementations, the specific form of the first environment IoT transmission resource configuration can be an AIoT MAC SDU, such as an AIoT MAC CE, or an AIoT RRC SDU, such as an AIoT RRC message.

[0138] In some implementations, the first message can be transmitted on a UL grant, DL assignment, or randomly selected resource that the terminal has already obtained.

[0139] S750: The AIoT device sends a second message to the terminal based on the configuration of IoT transmission resources in the first environment.

[0140] It should be understood that the explanation of the second message can be found above, and will not be repeated in this embodiment.

[0142] S770: The base station sends a service response message to the AIoT server.

[0143] It should be understood that the explanation of the service response message can be found above, and this application embodiment will not repeat it.

[0144] The following example illustrates the IoT communication method in the deployment scenario corresponding to Figure 4A.

[0145] Example 3, Figure 8 is an interactive flowchart of another environmental IoT communication method provided in an embodiment of this application. As shown in Figure 8, the method may include:

[0146] S810: The AIoT server sends a service request message to the base station; the service request message includes: the service characteristics of the IoT service in the target environment;

[0147] It should be understood that the explanations of the business request message, the target environment IoT business, and the business characteristics of the target environment IoT business can be found above, and will not be repeated in this application embodiment.

[0148] S820: The base station sends the service request message to the terminal;

[0149] S830: The terminal sends a first environment IoT resource configuration request to the base station; wherein, the first environment IoT resource configuration request includes: the service characteristics of the target environment IoT service;

[0150] In some implementations, the first environment IoT resource configuration request is used to request the configuration of first environment IoT resources.

[0151] In some implementations, the first environment IoT resource configuration request is used to request first environment IoT environment IoT resource configuration and third environment IoT environment IoT resource configuration, wherein the third environment IoT environment IoT resource configuration is used to transmit messages from the terminal to the AIoT device.

[0152] It should be noted that the third environment IoT resource configuration and the first environment IoT resource configuration can be requested through the same or different environment IoT resource configuration requests. In this example, the third environment IoT resource configuration and the first environment IoT resource configuration are requested through the same environment IoT resource configuration request.

[0153] S840: The base station determines the IoT transmission resource configuration for the first environment and the IoT transmission resource configuration for the third environment based on the service characteristics of IoT services in the target environment.

[0154] S850: The base station sends the first environment IoT transmission resource configuration and the third environment IoT transmission resource configuration to the terminal;

[0155] S860: The terminal sends a first message to the AIoT device; wherein, the first message includes: first environment IoT transmission resource configuration;

[0156] S870: The AIoT device sends a second message to the terminal based on the configuration of IoT transmission resources in the first environment.

[0157] It should be understood that the explanation of the second message can be found above, and will not be repeated in this embodiment.

[0158] In some implementations, the first environment IoT transmission resource configuration is relative to the environment IoT transmission resource configuration of the first message, i.e., the third environment IoT transmission resource configuration. For example, the time domain resource configuration included in the first environment IoT transmission resource configuration is the time offset relative to the reception time of the first message.

[0159] S880: The terminal sends a service response message to the base station.

[0160] S890: The base station sends a service response message to the AIoT server.

[0161] It should be understood that the explanation of the service response message can be found above, and this application embodiment will not repeat it.

[0162] In this embodiment, the environmental IoT transmission resource configuration of messages transmitted from the AIoT device to the environmental IoT reader can be determined based on the service characteristics of the target environmental IoT service associated with the AIoT device, and then communication between the AIoT device and the environmental IoT reader can be realized based on the resource configuration.

[0163] Figure 9 is an interactive flowchart of another environmental IoT communication method provided in this application embodiment. This method can be executed by an environmental IoT device, i.e., an AIoT device, and an environmental IoT reader. The environmental IoT device can be AIoT device 11 in Figure 1, AIoT device 21 in Figure 2, or AIoT devices in Figures 3, 4A, and 4B, but is not limited to these. The environmental IoT reader can be an access network device included in network-side device 12 in Figure 1, an access network device included in network-side device 23 in Figure 2, a base station in Figure 3, or a terminal in Figures 4A and 4B, but is not limited to these. The environmental IoT reader can also be referred to as a backscattering device, etc., and this application embodiment does not limit this. As shown in Figure 9, the method may include:

[0164] S910: The environmental IoT reader sends a first message to the environmental IoT device; wherein, the first message includes: a first environmental IoT transmission resource configuration; the first environmental IoT transmission resource configuration is determined based on the service characteristics of the target environmental IoT service;

[0165] S920: The environmental IoT device sends a second message to the environmental IoT reader based on the first environmental IoT transmission resource configuration;

[0166] It should be understood that the explanation of S910 can be found in the explanation of S510, and will not be repeated in this embodiment. The explanation of S920 can be found in the explanation of S520, and will not be repeated in this embodiment.

[0167] It should be noted that the embodiments of this application do not restrict the order of S920 with S930, S940, S950, S960, S970 and S980 respectively. For example, S930-S980 can be executed before S920, or S930-S970 can be executed before S920.

[0168] S930: The environmental IoT device determines the first data volume corresponding to the first environmental IoT transmission resource configuration;

[0169] In some possible implementations, there is a mapping relationship between the configuration of environmental IoT transmission resources and the amount of data. This application embodiment does not limit this mapping relationship.

[0170] Furthermore, the environmental IoT device can determine the first data volume corresponding to the first environmental IoT transmission resource configuration based on this mapping relationship and the first environmental IoT transmission resource configuration.

[0171] S940: If the first data volume is less than the second data volume, where the second data volume is the data volume from the environmental IoT device to the environmental IoT reader corresponding to the target environmental IoT service, then the environmental IoT device generates a second environmental IoT resource configuration request; wherein, the second environmental IoT resource configuration request is used to request the second environmental IoT transmission resource configuration.

[0172] It should be understood that the second data volume refers to the total data volume of all transmitted messages from the environmental IoT device to the environmental IoT reader corresponding to the target environmental IoT service. If the first data volume is less than the second data volume, it indicates that the first environmental IoT transmission resource configuration cannot meet the data transmission needs from the environmental IoT device to the environmental IoT reader. Based on this, the environmental IoT device can request a second environmental IoT transmission resource configuration through the second environmental IoT resource configuration. This second environmental IoT transmission resource configuration is used to transmit all messages from the environmental IoT device to the environmental IoT reader except for those transmitted through the first environmental IoT transmission resource configuration. For example, this second environmental IoT transmission resource configuration is used to transmit the fifth message, which will be mentioned below.

[0173] In some implementations, the target environment IoT service includes a specific service, or there exists a specific target environment IoT service, such as an inventory service, a read service, or a write service.

[0174] In some possible implementations, if the target environment IoT business includes a type of business, then the above-mentioned second environment IoT resource configuration request is unique.

[0175] In some implementations, the target environment IoT services include N types of services, or in other words, there are N types of target environment IoT services; where N is an integer greater than 1. For example, these include DO-A type services and DO-DTT type services, etc.

[0176] In some implementations, if the target environment's IoT services include N types of services, then each of the N types of services corresponds to a second environment IoT resource configuration request. For example, assuming there are DO-A and DO-DTT type services, then these two types of services each correspond to a second environment IoT resource configuration request.

[0177] In some possible implementations, the second environment IoT resource configuration request corresponding to each type of service includes at least one of the following:

[0178] The business type of this type of business;

[0179] The amount of data from environmental IoT devices to environmental IoT readers corresponds to this type of business;

[0180] This type of service corresponds to the transmission latency requirements from environmental IoT devices to environmental IoT readers.

[0181] In some implementations, if the target environment's IoT services include N types of services, then each of the N types of services corresponds to one second-environment IoT resource configuration request. For example, assuming there are DO-A and DO-DTT type services, then these two types of services correspond to one second-environment IoT resource configuration request.

[0182] In some possible implementations, if the target environment IoT services include N types of services, then a second environment IoT resource configuration request corresponding to these N types of services includes at least one of the following:

[0183] Each of the N types of business is a specific business type.

[0184] The amount of data from environmental IoT devices to environmental IoT readers corresponds to each of the N types of services;

[0185] The transmission latency requirements from environmental IoT devices to environmental IoT readers correspond to N types of services.

[0186] In this context, the second environment IoT resource configuration request can be understood as consisting of N sub-requests, each corresponding to a type of service, and each sub-request includes at least one of the following:

[0187] The business type of this type of business;

[0188] The amount of data from environmental IoT devices to environmental IoT readers corresponds to this type of business;

[0189] This type of service corresponds to the transmission latency requirements from environmental IoT devices to environmental IoT readers.

[0190] S950: The environmental IoT device sends a third message to the environmental IoT reader; wherein the third message includes a second environmental IoT resource configuration request;

[0191] S960: The environmental IoT reader responds to a second environmental IoT resource configuration request to determine the second environmental IoT transmission resource configuration;

[0192] Scenario 1: If the target environment IoT service includes a type of service, then there exists a second environment IoT transmission resource configuration, which includes at least one of the following: time domain resource configuration; frequency domain resource configuration; code domain resource configuration.

[0193] In the following situation:

[0194] In some implementations, the time-domain resource configuration included in the second environment IoT transmission resource configuration can be an absolute time-domain resource configuration, such as a protocol-predefined time-domain location indication, or a relative time-domain resource configuration, such as a time offset relative to the reception time of the first message.

[0195] In some implementations, the frequency domain resource configuration included in the second environment IoT transmission resource configuration can be an absolute frequency domain resource configuration, such as a frequency domain position indication predefined by the protocol, or a relative frequency domain resource configuration, such as a frequency domain offset relative to the receiving frequency domain position of the first message.

[0196] In some implementations, the code domain resource configuration included in the second environment IoT transmission resource configuration can be an absolute code domain resource configuration, such as a code domain position indication predefined by the protocol, or a relative code domain resource configuration, such as a code domain offset relative to the received codeword / text of the first message.

[0197] In some implementations, the environmental IoT reader is a terminal or an access network device. For example, in the wireless communication system shown in Figure 1 and in the AIoT device deployment scenario shown in Figure 3, the environmental IoT reader is an access network device, such as a base station; in the wireless communication system shown in Figure 2 and in the AIoT device deployment scenarios shown in Figures 4A and 4B, the environmental IoT reader is a terminal. Based on this, in the wireless communication system shown in Figure 1 and in the AIoT device deployment scenario shown in Figure 3, the access network device, such as a base station, can respond to a second environmental IoT resource configuration request to determine the second environmental IoT transmission resource configuration. In the wireless communication system shown in Figure 2 and in the AIoT device deployment scenarios shown in Figures 4A and 4B, the terminal or access network device can respond to a second environmental IoT resource configuration request to determine the second environmental IoT transmission resource configuration. In the AIoT device deployment scenario shown in Figure 4B, the terminal can respond to a second environmental IoT resource configuration request to determine the second environmental IoT transmission resource configuration. Whether the terminal or the access network device determines the second environmental IoT transmission resource configuration, it can use any of the following implementations, but is not limited to:

[0198] In some implementations, it is assumed that the second environmental IoT resource configuration request includes: the amount of data from the environmental IoT device to the environmental IoT reader corresponding to this type of service. The larger the data amount, the larger the time offset of the time-domain resource configuration included in the second environmental IoT transmission resource configuration relative to the reception time of the first message. There is a mapping relationship between this data amount and the time offset of the time-domain resource configuration included in the second environmental IoT transmission resource configuration relative to the reception time of the first message.

[0199] In some implementations, it is assumed that the second environmental IoT resource configuration request includes: the transmission latency requirement from the environmental IoT device to the environmental IoT reader corresponding to this type of service. The lower the transmission latency requirement, the greater the time offset of the time-domain resource configuration included in the second environmental IoT transmission resource configuration relative to the reception time of the first message. There is a mapping relationship between the transmission latency requirement and the time offset.

[0200] In some implementations, assuming the second environmental IoT resource configuration request includes the service type of the service, the amount of data from the environmental IoT device to the environmental IoT reader corresponding to that service type can be determined. The larger the data amount, the greater the time offset of the time-domain resource configuration included in the second environmental IoT transmission resource configuration relative to the reception time of the first message. There is a mapping relationship between the service type and the data amount.

[0201] In some implementations, assuming the second environmental IoT resource configuration request includes the service type of that type of service, the transmission latency requirement from the environmental IoT device to the environmental IoT reader corresponding to that type of service can be determined. The lower the transmission latency requirement, the greater the time offset of the time-domain resource configuration included in the second environmental IoT transmission resource configuration relative to the reception time of the first message. There is a mapping relationship between the service type and the transmission latency requirement.

[0202] In some implementations, if the second environmental IoT resource configuration request includes at least two of the following: the service type of the service; the amount of data from the environmental IoT device to the environmental IoT reader corresponding to the service type; and the transmission latency requirement from the environmental IoT device to the environmental IoT reader corresponding to the service type, then the highest priority of the at least two items can be selected, and the time offset of the time domain resource configuration included in the second environmental IoT transmission resource configuration relative to the reception time of the first message can be determined based on the highest priority item.

[0203] For example, suppose the business characteristics of the target environment IoT service include: the amount of data from the environmental IoT device to the environmental IoT reader corresponding to this type of service; the transmission latency requirement from the environmental IoT device to the environmental IoT reader corresponding to this type of service. Suppose that the transmission latency requirement has a higher priority. Based on this, if the transmission latency requirement is lower, the time offset of the time domain resource configuration included in the second environmental IoT transmission resource configuration relative to the reception time of the first message will be greater.

[0204] It should be noted that the methods for determining the frequency domain resource configuration and code domain resource configuration included in the second environment IoT transmission resource configuration are similar to the methods for determining the time domain resource configuration, and will not be repeated in the embodiments of this application.

[0205] Scenario 2: If the target environment IoT service includes N types of services, where N is an integer greater than 1, then there are M second environment IoT transmission resource configurations, where M is a positive integer. Each second environment IoT transmission resource configuration includes at least one of the following: time domain resource configuration; frequency domain resource configuration; code domain resource configuration.

[0206] In scenario two:

[0207] In some implementations, the time-domain resource configuration included in the second environment IoT transmission resource configuration can be an absolute time-domain resource configuration, such as a protocol-predefined time-domain location indication, or a relative time-domain resource configuration, such as a time offset relative to the reception time of the first message.

[0208] In some implementations, the frequency domain resource configuration included in the second environment IoT transmission resource configuration can be an absolute frequency domain resource configuration, such as a frequency domain position indication predefined by the protocol, or a relative frequency domain resource configuration, such as a frequency domain offset relative to the receiving frequency position of the first message.

[0209] In some implementations, the code domain resource configuration included in the second environment IoT transmission resource configuration can be an absolute code domain resource configuration, such as a code domain position indication predefined by the protocol, or a relative code domain resource configuration, such as a code domain offset relative to the received codeword / text of the first message.

[0210] In some implementations, the environmental IoT reader is a terminal or an access network device. For example, in the wireless communication system shown in Figure 1 and the AIoT device deployment scenario shown in Figure 3, the environmental IoT reader is an access network device, such as a base station; in the wireless communication system shown in Figure 2 and the AIoT device deployment scenarios shown in Figures 4A and 4B, the environmental IoT reader is a terminal. Based on this, in the wireless communication system shown in Figure 1 and the AIoT device deployment scenario shown in Figure 3, the access network device, such as a base station, can respond to a second environmental IoT resource configuration request to determine the second environmental IoT transmission resource configuration. In the wireless communication system shown in Figure 2 and the AIoT device deployment scenario shown in Figure 4A, the terminal or access network device can respond to a second environmental IoT resource configuration request to determine the second environmental IoT transmission resource configuration. In the AIoT device deployment scenario shown in Figure 4B, the terminal can determine the first environmental IoT transmission resource configuration based on the service characteristics of the target environmental IoT service. Whether the terminal or the access network device determines the second environmental IoT transmission resource configuration, it can use any of the following implementation methods, but is not limited to them:

[0211] In some implementation methods, the environmental IoT reader can determine the second environmental IoT transmission resource configuration based on the second environmental IoT transmission resource configuration request. If there are N types of services corresponding to N second environmental IoT transmission resource configuration requests, then one second environmental IoT transmission resource configuration can be determined based on each request, and the determination method can refer to the method described in Case 1 above. If there are N types of services corresponding to one second environmental IoT transmission resource configuration request, and as mentioned above, this one request is relative to N sub-requests, then one second environmental IoT transmission resource configuration can be determined based on each sub-request, and the determination method can refer to the method described in Case 1 above. In this implementation method, M = N, and there is a one-to-one correspondence between the N types of services and the M second environmental IoT transmission resource configurations.

[0212] In some implementations, the environmental IoT reader provides Q second environmental IoT transmission resource configurations to the environmental IoT device, where Q is an integer greater than 1. The environmental IoT device can determine the corresponding second environmental IoT transmission resource configuration for each type of service based on the Q second environmental IoT transmission resource configurations. Specifically, the environmental IoT device can determine the second environmental IoT transmission resource configuration based on a second environmental IoT transmission resource configuration request. If there are N types of services corresponding to N second environmental IoT transmission resource configuration requests, then one second environmental IoT transmission resource configuration can be determined based on each request, and the determination method can refer to the determination method in Case 1 above. If there are N types of services corresponding to one second environmental IoT transmission resource configuration request, as mentioned above, this one request is relative to N sub-requests, then one second environmental IoT transmission resource configuration can be determined based on each sub-request, and the determination method can refer to the determination method in Case 1 above. In this implementation, M = N, and there is a one-to-one correspondence between the N types of services and the M second environmental IoT transmission resource configurations.

[0213] In some implementations, N service types correspond to one second environmental IoT transmission resource configuration. That is, the environmental IoT reader provides a second environmental IoT transmission resource configuration to the environmental IoT device, and can allocate resources for each service type through the first and / or second indications carried in the fourth message below. In this implementation, M=1, and N service types correspond to one second environmental IoT transmission resource configuration.

[0214] In some possible implementations, the fourth message may also include at least one of the following: a first instruction and a second instruction;

[0215] The first indication is used to indicate the types of services that are allowed to be transmitted in the second environment IoT transmission resource configuration; the second indication is used to indicate the priority of the service types allowed to be transmitted in the second environment IoT transmission resource configuration when there are multiple service types. For example, the first indication is used to indicate whether DO-DTT and / or DO-A type service transmission is allowed; the second indication is used to indicate the transmission priority when multiple service types coexist, for example, DT > DO-DTT > DO-A.

[0216] S970: The environmental IoT reader sends a fourth message to the environmental IoT device; wherein, the fourth message includes the second environmental IoT transmission resource configuration;

[0217] S980: The environmental IoT device sends a fifth message to the environmental IoT reader based on the second environmental IoT transmission resource configuration.

[0218] In some feasible implementations, where there is a one-to-one correspondence between N types of services and M second environmental IoT transmission resource configurations, the environmental IoT device can send the fifth message corresponding to each type of service to the environmental IoT reader based on the second environmental IoT transmission resource configuration corresponding to each type of service.

[0219] In some possible implementations, where N types of services correspond to one second environmental IoT transmission resource configuration, the environmental IoT device can allocate transmission resources for some or all of the N types of services based on at least one of the first and second instructions and the second environmental IoT transmission resource configuration; the environmental IoT device sends the fifth message corresponding to some or all of the N types of services to the environmental IoT reader through the transmission resources.

[0220] For example, assuming that the second environmental IoT transmission resource configuration allows the transmission of DT services and DO-A services, and the priority of DT services is higher than that of DO-A services, the environmental IoT device can prioritize allocating transmission resources to DT services. If there are still remaining transmission resources, then the remaining transmission resources will be allocated to DO-A services. Based on this, the environmental IoT device sends the fifth message corresponding to the DT service to the environmental IoT reader through the transmission resources corresponding to the DT service, and sends the fifth message corresponding to the DO-A service to the environmental IoT reader through the transmission resources corresponding to the DO-A service.

[0221] It should be noted that the technical solutions constituted by S930 to S980 in Figure 9 can be combined with the structural solutions constituted by S910 to S920, or they can be decoupled from each other. The embodiments of this application do not impose any limitations on this. The technical solutions constituted by S930 to S980 are illustrated below through several examples.

[0222] Example 4, Figure 10 is an interaction flowchart of another environmental IoT communication method provided in the embodiments of this application. As shown in Figure 10, the method may include:

[0223] S1010: The base station sends a sixth message to the AIoT device; the sixth message includes: the fourth environment IoT environment IoT resource configuration;

[0224] It should be noted that the sixth message can be the first message mentioned above, and correspondingly, the fourth environmental IoT resource configuration can be the first environmental IoT resource configuration mentioned above. Of course, the sixth message may not be the first message mentioned above, and correspondingly, the fourth environmental IoT resource configuration may not be the first environmental IoT resource configuration mentioned above.

[0225] S1020: The AIoT device determines the third data volume corresponding to the IoT transmission resource configuration in the fourth environment;

[0226] S1030: If the third data volume is less than the second data volume, where the second data volume is the data volume from the environmental IoT device to the environmental IoT reader corresponding to the target environmental IoT service, then the AIoT device generates a second environmental IoT resource configuration request; wherein, the second environmental IoT resource configuration request is used to request the configuration of the second environmental IoT transmission resources.

[0227] In some possible implementations, if the target environment IoT services include N types of services, then each of the N types of services corresponds to a second environment IoT resource configuration request.

[0228] In some possible implementations, the second environment IoT resource configuration request corresponding to each type of service includes at least one of the following:

[0229] The business type of this type of business; for example, DT type, DO-DTT type, or DO-A type;

[0230] The amount of data from environmental IoT devices to environmental IoT readers corresponds to this type of business;
