[0001] The present application claims priority to the Chinese patent application No. 202411101358.3, filed on August 9, 2024, and entitled "Resource indication method, terminal device, network device, communication apparatus and medium", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication technology, in particular to a resource indication method, a terminal device, a network device, a communication apparatus and a medium. BACKGROUND

[0003] In the field of wireless communication, more and more "things" are connected to each other through the Internet of Things (IoT) to improve production efficiency and improve the comfort of life. In order to further reduce the size, complexity and power consumption of Internet of Things devices, hundreds of billions or even trillions of Internet of Things devices can be deployed for various applications. Based on the Internet of Things scenario, Ambient-IoT (A-IoT) will become the main source of the trillion-level Internet of Things connection scenario.

[0004] At present, the identification of terminal devices mainly relies on bar codes and radio frequency identification (RFID), and since the coverage distance is only about 10 meters, it is difficult to support the use demand of the future trillion-level scale. The 3rd Generation Partnership Project (3GPP) is discussing the development of Ambient-IoT technology based on cellular communication, which can reduce costs by using existing large-scale cellular infrastructure and can also improve the coverage of Ambient-IoT by using cellular communication.

[0005] In a real network environment, there are multiple types of terminal devices, and how to allocate resources is a problem to be solved in the field. SUMMARY

[0006] The present application provides a resource indication method, a terminal device, a network device, a communication apparatus and a medium, which aims to allocate resources to terminal devices with or without Ambient-IoT capability and carrier capability.

[0007] In order to achieve the above purpose, the present application provides the following technical solutions:

[0008] The first aspect of the present application provides a resource indication method applied to a terminal device, the method comprising:

[0009] The first information is sent to a network device, and the first information is used to report whether the terminal device has an environmental Internet of Things capability and whether the terminal device has a carrier wave (CW) generation capability.

[0010] The first control information is received from the network device, wherein,

[0011] The terminal device has the environmental Internet of Things capability, and the first control information is used to indicate a first resource, and the first resource is used for communication between the terminal device and an environmental Internet of Things device.

[0012] The terminal device has the carrier wave generation capability, and the first control information is further used to indicate a second resource, and the second resource is used for the terminal device to send an excitation signal to the environmental Internet of Things device.

[0013] The first resource and the second resource are different resources.

[0014] In the above scheme, the network device determines that the terminal device has the environmental Internet of Things capability, and the network device can allocate the first resource, and the first resource is used for communication between the terminal device and the environmental Internet of Things device. The network device determines that the terminal device has the carrier wave generation capability, and the network device can allocate the second resource, and the second resource is used for the terminal device to send the excitation signal to the environmental Internet of Things device. The first resource and the second resource allocated by the network device are different resources, so that the network device can control the terminal device according to the allocated first resource and the second resource, and perform efficient allocation of resources for the environmental Internet of Things capability and resources for the carrier wave generation capability, and improve the resource utilization rate of the terminal device.

[0015] In a possible implementation manner of the first aspect of the present application, the first information is sent in a static, semi-static, or dynamic manner. In the above scheme, the terminal device and the network device are configured with a communication connection, and the terminal device has multiple ways to send the first information. The first information can be sent in a static, semi-static, or dynamic manner, as long as the network device can receive the first information.

[0016] In a possible implementation manner of the first aspect of the present application, the first information is sent in a static manner, including: sending first radio resource control (RRC) signaling, and the first RRC signaling is used to carry the first information.

[0017] Alternatively,

[0018] The first information is sent in a semi-static manner, including: sending a first medium access control (MAC) control element (CE), and the first MAC CE is used to carry the first information.

[0019] Or,

[0020] The first information is sent in a dynamic manner, including: sending first uplink control information (UCI) used to carry the first information.

[0021] In the above scheme, the terminal device can send the first information to the network device by using RRC signaling, or MAC CE, or UCI, and the network device can receive the RRC signaling, or MAC CE, or UCI to obtain the first information. In actual application scenarios, other signaling or messages can also be used to send the first information to the network device, and the above-mentioned signaling or messages are only possible implementation manners, and are not a limitation on the embodiments of the present application.

[0022] In a possible implementation manner of the first aspect of the present application, the first control information is received in a static, or semi-static, or dynamic manner. In the above scheme, the terminal device and the network device are configured with a communication connection, and the network device has multiple ways to send the first control information, as long as the terminal device can receive the first control information.

[0023] In a possible implementation manner of the first aspect of the present application, the first control information is received in a static manner, including: receiving second radio resource control (RRC) signaling used to carry the first control information.

[0024] Or,

[0025] The first control information is received in a semi-static manner, including: receiving a second medium access control control element (MAC CE) used to carry the first control information.

[0026] Or,

[0027] The first control information is received in a dynamic manner, including: receiving downlink control information (DCI) used to carry the first control information.

[0028] In the above scheme, the network device interacts with the terminal device, and the network device can send the first control information to the terminal device by using RRC signaling, or MAC CE, or DCI. Correspondingly, the terminal device can receive the RRC signaling, or MAC CE, or DCI to obtain the first control information.

[0029] In a possible implementation of the first aspect of the application, the first resource and the second resource have a mapping relationship. In the above solution, when the terminal device has the environmental Internet of Things capability and the capability of generating a carrier, the network device can allocate the first resource and the second resource to the terminal device. In order to improve the resource utilization, the first resource and the second resource have a mapping relationship, that is, the first resource and the second resource have a special corresponding or mapping type. For example, the first resource and the second resource have a frequency division multiplexing relationship, or the first resource and the second resource can be mapped together in an interleaved manner. For example, when the first resource and the second resource partially overlap or completely overlap in the frequency domain, they are time division multiplexed in the time domain. For another example, the first resource and the second resource can use the same resource in the time domain, but use different frequency domain resources in the frequency domain. Therefore, the first resource and the second resource do not produce strong interference in self-checking, and the resource utilization can be improved.

[0030] In a possible implementation of the first aspect of the application, the first resource includes a resource for communication between the reader and the environmental Internet of Things device, and a resource for communication between the environmental Internet of Things device and the reader.

[0031] The second resource and the resource for communication between the reader and the environmental Internet of Things device are mapped in an interleaved manner, and the second resource and the resource for communication between the environmental Internet of Things device and the reader are the same resource.

[0032] In the above solution, the resource for communication between the reader and the environmental Internet of Things device represents a resource for the reader to send data to the environmental Internet device, and the resource for communication between the environmental Internet of Things device and the reader represents a resource for the environmental Internet of Things device to send to the reader. The second resource and the resource for communication between the reader and the environmental Internet of Things device are mapped in an interleaved manner, and the second resource and the resource for communication between the environmental Internet of Things device and the reader are the same resource. Through the interleaved mapping of the first resource and the second resource, the utilization of the resource allocated by the network device to the terminal device can be improved.

[0033] In a possible implementation of the first aspect of the application, the second resource includes an uplink frequency domain resource or a downlink frequency domain resource of frequency division duplex (FDD). In the above solution, the second resource allocated by the network device can be an uplink frequency domain resource of frequency division duplex or a downlink frequency domain resource of frequency division duplex. Therefore, when the terminal device has the capability of generating a CW, it can use the uplink frequency band or the downlink frequency band of frequency division duplex to send an excitation signal to the environmental Internet of Things device.

[0034] In a possible implementation of the first aspect of the application, the first control information is used to indicate that the resource mapping type corresponding to the second resource is continuous resource mapping or non-continuous resource mapping.

[0133] The Internet of Things (IoT) can be classified into high-speed, medium-speed and low-speed IoT according to the transmission rate of nodes. Among them, the low-speed IoT can support hundreds of billions of connections, and the connection scale of medium-speed and high-speed IoT is much lower than that of low-speed IoT. On the basis of the above three types of IoT scenarios, Ambient-IoT (A-IoT) will become the main source of hundreds of billions of IoT connection scenarios, and Ambient-IoT can also be called passive IoT, simply called passive IoT. The main application scenarios of passive IoT system are illustrated by examples:

[0134] Passive IoT can be specifically applied to industrial sensor networks. Industrial sensor networks are mainly applied in industrial production processes, such as temperature and humidity monitoring, vibration monitoring, and production line monitoring, so as to realize industrial automation and intelligent management. Taking rail measurement as an example, by deploying zero-power sensing devices under the rail, the rail pressure, temperature and other information can be monitored and collected. In addition, related devices can also be deployed in extreme environments such as high and low temperature, mobile or rotating parts, high vibration conditions, and high humidity, where batteries cannot last long.

[0135] Passive IoT can be specifically applied to logistics and warehouse scenarios. With the continuous growth of the logistics industry, the pressure on enterprise warehousing and labor costs is increasing. Digital management of logistics packages can not only further improve logistics and warehouse management efficiency, but also save high labor costs. Passive IoT can realize zero-power communication, and zero-power communication can be used for logistics information acquisition and logistics whole-process management by attaching a communication terminal identifier to the surface of the package or the packaging of goods, making warehouse operations more simple and efficient.

[0136] Passive IoT can be specifically applied to smart wearable scenarios. Smart wearable products are personal consumer terminals with potential for large-scale application after mobile phones. Various wearable devices have achieved wireless connection. According to the functional positioning of different products, health monitoring, motion monitoring, mobile sensing, mobile positioning and other multi-scenario applications can be realized. Passive IoT can realize zero-power communication, and the goal of zero-power communication technology is to ultimately break free from battery constraints, achieve longer battery life, more convenient energy supply and better user experience.

[0137] Passive IoT can be specifically applied to medical and health scenarios. Portable medical devices can meet the needs of consumers for home health services, but due to the special nature of medical monitoring devices (especially human implantable devices), the problems of battery life and power carrying have limited the expansion of their application scenarios to a large extent. Through zero-power IoT technology, very low power consumption can be achieved; at the same time, without a battery, the device size can be reduced, which is conducive to realizing flexible folding and not worrying about liquid immersion, which will help real-time monitoring of medical device data and efficient digital management of health status.

[0138] Passive IoT can be applied to smart home scenarios. In the field of smart home, zero-power communication technology can be applied to get rid of complex wiring, enable independent control of each terminal, and achieve long-lasting online without human energy intervention.

[0139] Next, the wireless radio frequency identification (RFID) technology in the industry is described. RFID is an automatic identification technology that performs non-contact bidirectional data communication through wireless radio frequency and reads and writes a recording medium (such as an electronic tag or a radio frequency card) through wireless radio frequency, thereby achieving the purpose of identifying targets and data exchange.

[0140] However, this RFID technology has a coverage distance of only about 10 meters (m), and therefore, it is difficult to support the use demand of hundreds of billions of scale in the future. The 3rd Generation Partnership Project (3GPP) is discussing the formulation of passive IoT technology based on cellular communication, which can reduce costs by using existing large-scale cellular infrastructure and can also use cellular communication to improve the coverage range of passive IoT, such as interference management, mobility management, and other technologies.

[0141] The device types of the environmental IoT device are introduced as follows:

[0142] Device 1: The peak power consumption is about 1 micro-watt, has energy storage, and the initial sampling frequency offset (SFO) is up to 10 X ppm, and there is neither downlink nor uplink amplifier in the device. The uplink transmission of the device is backscattered on the externally provided carrier.

[0143] Device 2a: The peak power consumption is not more than a few hundred micro-watts, has energy storage, and the initial sampling frequency offset (SFO) is up to 10 X ppm, and there is a downlink and / or uplink amplifier in the device. The uplink transmission of the device is backscattered on the externally provided carrier.

[0144] Device 2b: The peak power consumption is not more than a few hundred micro-watts, has energy storage, and the initial sampling frequency offset (SFO) is up to 10 X ppm, and there is a downlink and / or uplink amplifier in the device. The uplink transmission of the device is backscattered on the externally provided carrier.

[0145] Representative uses of environmental IoT devices are as follows: rUC1 represents indoor inventory, rUC2 represents indoor sensors, rUC3 represents indoor positioning, and rUC4 represents indoor command.

[0146] In order to make the technical solutions of the present application clearer and easier to understand, the frequency domain resource indication method of the embodiments of the present application will be introduced below in conjunction with the drawings. The embodiments of the present application are applicable to the data transmission process in a wireless communication scenario. In the embodiments of the present application, the resource indication between a terminal device and a network device is taken as an example, such as the resource indication between a single terminal device and a network device, or the resource indication between multiple terminal devices and a network device. The resource indication between the terminal device and the network device described above is only an example, and the embodiments of the present application can be applied to the data transmission between terminal devices, or the data transmission between network devices, or the data transmission between two network elements in a wireless communication network.

[0147] Different devices have different requirements for resource allocation, and how to allocate resources is a problem to be solved in the art. Referring to FIG. 3, an interactive process diagram between a terminal device and a network device is provided in the embodiments of the present application. In addition to interacting with the network device, the terminal device can also interact with an environmental IoT device, for example, the terminal device can be an intermediate terminal device.

[0148] The resource indication method provided by the embodiments of the present application mainly includes the following steps:

[0149] 301. The terminal device sends first information to the network device.

[0150] The first information is used to report whether the terminal device has environmental IoT capability and whether the terminal device has the ability to generate a carrier CW.

[0151] In the embodiments of the present application, the terminal device can report the capability information of the terminal device to the network device, so that the network device parses the capability information of the terminal device to determine the capability of the terminal device. The first information is used to report the capability information of the terminal device to the network device, and the first information can also be referred to as first reporting information, first reporting request, or first message, or first indication, etc. Specifically, the capability of the terminal device can include whether the terminal device has the environmental Internet of Things capability, for example, the terminal device has the environmental Internet of Things capability or not is indicated by different values carried in the first information. For example, the capability of the terminal device can include whether the terminal device has the capability of generating a carrier wave (CW), for example, whether the terminal device has the capability of generating a carrier wave (CW) is indicated by different values carried in the first information. In addition, the first information can also indicate whether the terminal device has the environmental Internet of Things capability and whether the terminal device has the capability of generating a carrier wave (CW).

[0152] In some embodiments of the present application, a communication connection is configured between the terminal device and the network device, and the terminal device has multiple ways to send the first information, as long as the network device can receive the first information. Specifically, the first information is sent in a static, semi-static, or dynamic manner. The terminal device can send the first information in a static manner, for example, the terminal device sends the first information when accessing the network device. The terminal device can also send the first information in a semi-static manner, for example, the terminal device sends the first information to the network device when the channel environment changes. The terminal device can also send the first information in a dynamic manner, for example, the terminal device sends the first information to the network device multiple times, so that the network device can obtain the latest first information.

[0153] Further, in some embodiments of the present application, the first information is sent in a static manner, including: the terminal device sends first radio resource control (RRC) signaling, and the first radio resource control (RRC) signaling is used to carry the first information.

[0154] Or,

[0155] The first information is sent in a semi-static manner, including: the terminal device sends a first media access control control element (MAC CE), and the first media access control control element (MAC CE) is used to carry the first information.

[0156] Or,

[0157] The first information is sent in a dynamic manner, including: the terminal device sending first uplink control information (UCI), the first uplink control information UCI being used to carry the first information.

[0158] In the embodiments of the present application, the terminal device can send the first information to the network device by using RRC signaling, or MAC CE, or UCI, and the network device can receive the RRC signaling, or MAC CE, or UCI to obtain the first information. In actual application scenarios, other signaling or messages can also be used to send the first information to the network device, and the above-mentioned signaling or messages are only some possible implementation manners, and do not limit the embodiments of the present application.

[0159] In some embodiments of the present application, the first information further includes a unique identifier (ID) of the terminal device and a proximity result, and the proximity result includes information of an environmental Internet of Things device adjacent to the terminal device.

[0160] For example, the unique identifier of the terminal device can be the identifier of a reader.

[0161] The terminal device can also report the proximity result to the network device, the proximity result including information of an environmental Internet of Things device adjacent to the terminal device, and the network device can determine the information of the environmental Internet of Things adjacent to the terminal device according to the proximity result, for example, the proximity result includes: the identifier ID of the environmental Internet of Things device close to the terminal device, or the number of environmental Internet of Things devices, etc.

[0162] 311、The network device receives the first information from the terminal device.

[0163] The first information is used to report whether the terminal device has environmental Internet of Things capability and whether the terminal device has the capability to generate a carrier.

[0164] Specifically, the capability of the terminal device can include whether the terminal device has environmental Internet of Things capability, for example, different values carried by the first information are used to indicate whether the terminal device has environmental Internet of Things capability. For another example, the capability of the terminal device can include whether the terminal device has the capability to generate a CW, for example, different values carried by the first information are used to indicate whether the terminal device has the capability to generate a CW. In addition, the first information can also indicate whether the terminal device has environmental Internet of Things capability and whether the terminal device has the capability to generate a carrier CW. The network device can determine whether the terminal device has environmental Internet of Things capability and whether the terminal device has the capability to generate a carrier CW by analyzing the first information.

[0165] In some embodiments of the present application, the first information is received in a static manner, including: receiving, by the network device, first radio resource control (RRC) signaling, the first RRC signaling being used to carry the first information;

[0166] Alternatively,

[0167] The first information is received in a semi-static manner, including: receiving, by the network device, a first medium access control (MAC) control element (CE), the first MAC CE being used to carry the first information;

[0168] Alternatively,

[0169] The first information is received in a dynamic manner, including: receiving, by the network device, first uplink control information (UCI), the first UCI being used to carry the first information.

[0170] Specifically, the network device interacts with the terminal device, and the terminal device can send the first information to the network device by using RRC signaling, or a MAC CE, or UCI. Correspondingly, the network device can receive the RRC signaling, or the MAC CE, or the UCI to obtain the first information.

[0171] 312. The network device sends first control information to the terminal device.

[0172] The terminal device has an environmental Internet of Things capability, and the first control information is used to indicate a first resource, the first resource being used for communication between the terminal device and an environmental Internet of Things device.

[0173] The terminal device has a carrier generation capability, and the first control information is further used to indicate a second resource, the second resource being used for the terminal device to send an excitation signal to the environmental Internet of Things device.

[0174] The first resource and the second resource are different resources.

[0175] Specifically, after receiving the first information from the terminal device, the network device parses the first information, and can determine whether the terminal device has the environmental Internet of Things capability and whether the terminal device has the capability of generating a carrier CW. For example, the terminal device has the environmental Internet of Things capability, and the network device can allocate resources for the terminal device to communicate with the environmental Internet of Things device. The terminal device does not have the environmental Internet of Things capability, and the network device does not need to allocate resources for the terminal device to communicate with the environmental Internet of Things device. For another example, the terminal device has the capability of generating a carrier, and the network device can allocate resources for the terminal device to send an excitation signal to the environmental Internet of Things device. The terminal device does not have the capability of generating a carrier, and the network device does not need to allocate resources for the terminal device to send an excitation signal to the environmental Internet of Things device. In addition, when the terminal device has the environmental Internet of Things capability and has the capability of generating a carrier, the network device needs to allocate corresponding resources according to the environmental Internet of Things capability and the capability of generating a carrier of the terminal device. In the embodiment of the present application, the resources allocated by the network device for the terminal device can be time domain resources and / or frequency domain resources.

[0176] For example, the network device determines whether the UE has an A-IoT function and has the capability of generating a CW according to the first information. Therefore, the network device can effectively identify the intermediate UE that supports the A-IoT function and has a CW inside, and can efficiently allocate resources to the intermediate UE. The resources can include time domain resources, frequency domain resources, and time-frequency domain resources of the CW.

[0177] Specifically, the network device determines that the terminal device has the environmental Internet of Things capability, and the network device can allocate first resources for the terminal device to communicate with the environmental Internet of Things device. The network device determines that the terminal device has the capability of generating a carrier, and the network device can allocate second resources for the terminal device to send an excitation signal to the environmental Internet of Things device. The first resources and the second resources allocated by the network device are different resources, so that the network device can control the terminal device according to the allocated first resources and second resources, and efficiently allocate resources for the environmental Internet of Things capability and resources for the capability of generating a carrier.

[0178] In the embodiment of the present application, after the network device determines the resources to be allocated, the network device generates first control information to indicate the resources allocated by the network device, and sends the first control information to the terminal device, so that the terminal device receives the first control information and obtains the resources allocated by the network device by parsing the first control information.

[0179] In some embodiments of the present application, a communication connection is configured between the terminal device and the network device, and the network device transmits the first control information in various ways as long as the terminal device can receive the first control information. Specifically, the first control information is transmitted in a static, semi-static, or dynamic manner.

[0180] In some embodiments of the present application, the first control information is transmitted in a static manner, including that the network device transmits second radio resource control (RRC) signaling, and the second RRC signaling is used to carry the first control information.

[0181] Alternatively,

[0182] The first control information is transmitted in a semi-static manner, including that the network device transmits a second medium access control (MAC) control element (CE), and the second MAC CE is used to carry the first control information.

[0183] Alternatively,

[0184] The first control information is transmitted in a dynamic manner, including that the network device transmits downlink control information (DCI), and the DCI is used to carry the first control information.

[0185] In the embodiments of the present application, the network device can transmit the first control information to the network device by using RRC signaling, or MAC CE, or DCI, and the terminal device can receive the RRC signaling, or MAC CE, or DCI to obtain the first control information. In actual application scenarios, other signaling or messages can also be used to transmit the first control information to the terminal device, and the above-mentioned signaling or messages are only some possible implementation manners, and do not limit the embodiments of the present application.

[0186] In some embodiments of the present application, the resource allocated by the network device can be a time domain resource, the first resource includes a first continuous resource, and the second resource includes a second continuous resource.

[0187] The first continuous resource and the second continuous resource are different continuous resources.

[0188] In the embodiments of the present application, the network device can allocate the first continuous resource, and the network device indicates the first starting symbol and the allocated symbol length by the first control information. The network device can allocate the second continuous resource, and the network device indicates the second starting symbol and the allocated symbol length by the first control information. The first continuous resource and the second continuous resource are different continuous resources, so as to further improve the resource utilization rate.

[0189] In some embodiments of the present application, the first resource includes: a resource for the reader to communicate with the environmental Internet of Things device, and a resource for the environmental Internet of Things device to communicate with the reader;

[0190] The second resource and the resource for the reader to communicate with the environmental Internet of Things device are mapped in an interleaved manner, and the second resource and the resource for the environmental Internet of Things device to communicate with the reader are the same resource.

[0191] The resource for the reader to communicate with the environmental Internet of Things device represents a resource for the reader to send data to the environmental Internet of Things device, and the resource for the environmental Internet of Things device to communicate with the reader represents a resource for the environmental Internet of Things device to send to the reader. The second resource and the resource for the reader to communicate with the environmental Internet of Things device are mapped in an interleaved manner, and the second resource and the resource for the environmental Internet of Things device to communicate with the reader are the same resource. Through the interleaved mapping of the first resource and the second resource, the utilization rate of the network device allocating resources for the terminal device can be improved.

[0192] In some embodiments of the present application, the first resource and the second resource have a mapping relationship.

[0193] When the terminal device has environmental Internet of Things capability and has the ability to generate a carrier, the network device can allocate the first resource and the second resource to the terminal device. In order to improve the utilization rate of resources, the first resource and the second resource have a mapping relationship, that is, the first resource and the second resource have a special corresponding or mapping type. For example, the first resource and the second resource have a frequency division multiplexing relationship, or the first resource and the second resource can be mapped together in an interleaved manner. For example, when the first resource and the second resource partially or completely overlap in the frequency domain, they are time division multiplexed in the time domain. For another example, the first resource and the second resource can use the same resource in the time domain, but use different frequency domain resources in the frequency domain, so that the first resource and the second resource do not produce strong interference in self-checking, and the utilization rate of resources can be improved.

[0194] In some embodiments of the present application, the second resource allocated by the network device can be a frequency domain resource, and the second resource includes: an uplink frequency domain resource or a downlink frequency domain resource of frequency division duplexing (FDD).

[0195] The second resource allocated by the network device can be an uplink frequency domain resource or a downlink frequency domain resource of frequency division duplexing, so when the terminal device has the ability to generate a CW, it can use the uplink frequency band or the downlink frequency band of frequency division duplexing to send an excitation signal to the environmental Internet of Things device.

[0196] Further, in some embodiments of the present application, the first control information is used to indicate that the resource mapping type corresponding to the second resource is continuous resource mapping or non-continuous resource mapping.

[0197] In the embodiments of the present application, the mapping type of the second resource configured by the network device can be continuous resource mapping or non-continuous resource mapping, and the specific application scenario is determined. The first control information is used to indicate that the resource mapping type corresponding to the second resource is continuous resource mapping or non-continuous resource mapping, so as to realize flexible configuration for the second resource.

[0198] In some embodiments of the present application, the first control information is also used to indicate the frequency band deployment mode of the terminal device.

[0199] In some embodiments of the present application, the network device can also configure the frequency band used by the terminal device having the CW generation capability, and indicate the frequency band deployment mode of the terminal device through the first control information.

[0200] Specifically, the network device can configure the frequency band deployment mode of the terminal device as an in-band mode, a guard band mode, or an independent frequency band mode.

[0201] In the in-band mode, the terminal device having the CW generation capability needs to coexist with the terminal device of the NR system. The network device configures the second resource, which can be used by the terminal device to send the excitation signal to the environmental IoT device. The terminal device determines the corresponding second resource according to that the frequency band deployment mode is the in-band mode.

[0202] In addition, the network device can configure the frequency band deployment mode of the terminal device as a guard band mode, that is, the network device can configure the guard band of the terminal device in the NR system for the second resource. The terminal device can send the excitation signal to the environmental IoT device in the guard band.

[0203] In addition, the network device can configure the frequency band deployment mode of the terminal device as an independent frequency band mode, that is, the network device can allocate an independent frequency band completely different from the resource of the terminal device of the NR system for the terminal device having the CW generation capability. The network device can send the excitation signal to the environmental IoT device in the independent frequency band.

[0204] In some embodiments of the present application, the first control information is also used to indicate whether the terminal device has frequency hopping capability and the corresponding offset.

[0205] The network device determines that the terminal device has the capability of generating a carrier CW, and the network device can further determine whether the terminal device needs frequency hopping. When it is determined that the terminal device needs frequency hopping, an offset corresponding to the frequency hopping is acquired. The network device determines that the first control information indicates whether the terminal device has the frequency hopping capability and the corresponding offset, so that the terminal device performs the frequency hopping operation according to the first control information.

[0206] In some embodiments of the present application, the resource allocated by the network device can be a time domain resource. The first control information is further used to indicate that the second resource is a periodically configured time domain resource, or a semi-persistently configured time domain resource, or a non-periodically configured time domain resource.

[0207] The network device can configure the second resource in a periodic manner, or in a semi-persistent manner, or in a non-periodic manner. The embodiments of the present application do not limit the manner in which the network device configures the second resource, and the specific manner can be determined in combination with the application scenario.

[0208] 302. The terminal device receives the first control information from the network device.

[0209] Specifically, the network device sends the first control information to the terminal device, so that the terminal device receives the first control information and acquires the resource allocated by the network device by analyzing the first control information. The terminal device has the environmental Internet of Things capability, and determines the first resource according to the first control information. The first resource is used for communication between the terminal device and the environmental Internet of Things device. The terminal device has the capability of generating a carrier CW, and determines the second resource according to the first control information. The second resource is used for the terminal device to send an excitation signal to the environmental Internet of Things device. In the embodiments of the present application, when the terminal device has both the environmental Internet of Things capability and the capability of generating a carrier, the terminal device can acquire the first resource and the second resource, which are different resources. The specific configuration of the first resource and the second resource is not limited in the embodiments of the present application.

[0210] In some embodiments of the present application, the first control information is received in a static manner, including: the terminal device receives second radio resource control (RRC) signaling, and the second RRC signaling is used to carry the first control information.

[0211] Alternatively,

[0212] The first control information is received in a semi-static manner, including: the terminal device receives a second medium access control (MAC) control element (CE), and the second MAC CE is used to carry the first control information.

[0213] Alternatively,

[0214] The first control information is received in a dynamic manner, including: the terminal device receives downlink control information DCI, and the downlink control information DCI is used to carry the first control information.

[0215] Specifically, the network device interacts with the terminal device, and the network device can send the first control information to the terminal device by using RRC signaling, or MAC CE, or DCI. Correspondingly, the terminal device can receive the RRC signaling, or the MAC CE, or the DCI to obtain the first control information.

[0216] In some embodiments of the present application, the resource indication method provided by the embodiments of the present application further includes:

[0217] A1, the terminal device sends second information to the network device, and the second information is used to indicate the size of data stored or buffered by the terminal device;

[0218] A2, the network device receives the second information from the terminal device, and the second information is used to indicate the size of data stored or buffered by the terminal device;

[0220] A4, the terminal device receives the second control information from the network device, and the second control information is used to indicate the third resource, and the third resource is used to send data to the network device.

[0221] The terminal device can store or buffer a certain amount of data, and the data is used for the terminal device to report to the network device. For example, the terminal device interacts with the environmental Internet of Things device, the terminal device stores or buffers the data generated in the interaction process, for example, the data can be Inventory, Command, Sensors, Positioning use case data, and the terminal device needs to report the data to the network device. The terminal device first sends second information to the network device, and the second information indicates the size of the data stored or buffered by the terminal device. The network device receives the second information and can determine the size of the data. Then, the network device allocates a third resource, and the third resource can be used for the terminal device to report the data. The network device sends second control information, and the second control information indicates the third resource. After the terminal device receives the second control information, the terminal device parses the second control information to determine the third resource. The terminal device sends the data stored or buffered by the terminal device according to the third resource, so as to complete the reporting of the data from the terminal device to the network device.

[0222] For example, the third resource and the first resource, the second resource can be different resources. In order to improve the resource utilization, there is a mapping relationship between the first resource and the third resource, which will be described in detail in the foregoing example of the mapping relationship between the first resource and the second resource. There is a mapping relationship between the second resource and the third resource, which will be described in detail in the foregoing example of the mapping relationship between the first resource and the second resource.

[0223] In some embodiments of the application, the first control information is also used to indicate a fourth resource, and the fourth resource is used for the terminal device to report the first result to the network device, and the first result includes an intermediate result or a final result obtained by the terminal device in communication with the environmental Internet of Things device.

[0224] The terminal device obtains the first result, and the first result includes an intermediate result or a final result obtained by the terminal device in communication with the environmental Internet of Things device. The first control information sent by the network device is also used for the fourth resource, and the fourth resource is used for communication between the terminal device and the network device. Specifically, the fourth resource is used for the terminal device to report the first result to the network device. For example, the terminal device communicates with the environmental Internet of Things device to obtain the result of the Inventory / Command / Sensors / Positioning use case. The result reporting can be for a specific environmental Internet of Things device, or for multiple environmental Internet of Things devices under a terminal device service, or for a result after one round of aggregation, or for a result after multiple rounds of aggregation, which is not limited here.

[0225] In the embodiments of the application, the first control information can indicate the fourth resource, so that the network device can control the terminal device according to the allocated fourth resource, and the terminal device can use the fourth resource to send the first result, thereby improving the resource utilization of the terminal device.

[0226] For example, the fourth resource and the first resource, the second resource can be different resources. In order to improve the resource utilization, there is a mapping relationship between the first resource and the third resource, which will be described in detail in the foregoing example of the mapping relationship between the first resource and the second resource. There is a mapping relationship between the second resource and the third resource, which will be described in detail in the foregoing example of the mapping relationship between the first resource and the second resource.

[0227] For example, in addition to indicating the first resource and the second resource, the first control information can also indicate the fourth resource. The first resource is used for the intermediate UE to communicate with the A-IOT device, the second resource is used for the intermediate UE to send the excitation signal, and the fourth resource is used for the UE to communicate with the network device. The embodiments of the application can solve the uplink / downlink UL / DL coexistence interference problem with the NR UE. Specifically, the first control information can be efficiently controlled and indicated through different levels of air interface signaling, such as using layer 1 or layer 2 or layer 3 signaling to send the first control information.

[0228] In some embodiments of the present application, the resource indication method provided by the embodiments of the present application further comprises:

[0229] The terminal device sends the first result to the network device in a periodic, semi-persistent, or aperiodic manner according to the fourth resource.

[0230] The network device receives the first result from the terminal device in a periodic, semi-persistent, or aperiodic manner according to the fourth resource.

[0231] The terminal device can send the first result in a periodic, semi-persistent, or aperiodic manner. The embodiments of the present application do not limit the manner in which the terminal device sends the first result, and the specific manner can be determined in combination with the application scenario.

[0237] Further, in some embodiments of the present application, the network device receives the first result from the terminal device in a periodic manner, comprising: the network device receives third radio resource control RRC signaling, and the third radio resource control RRC signaling is used to carry the first result.

In actual application scenarios, other signaling or messages can also be used to send the first result to the network device, and the above-mentioned signaling or messages are only possible implementation manners, and do not limit the embodiments of the present application.

[0243] As can be known from the foregoing examples, in the embodiments of the present application, the network device determines that the terminal device has the environmental Internet of Things capability, and the network device can allocate the first resource, which is used for communication between the terminal device and the environmental Internet of Things device. The network device determines that the terminal device has the capability of generating a carrier, and the network device can allocate the second resource, which is used for the terminal device to send an excitation signal to the environmental Internet of Things device. The first resource and the second resource allocated by the network device are different resources, so that the network device can control the terminal device according to the allocated first resource and second resource, and perform efficient allocation of resources for the environmental Internet of Things capability and resources for the capability of generating a carrier, thereby improving the resource utilization rate of the terminal device.

[0244] Specifically, the embodiments of the present application provide the following technical solutions to solve the problem of resource allocation of devices with different capabilities.

[0245] In view of the problems existing in the above-mentioned scenarios or in order to realize the above-mentioned scenarios, the main technical solutions of the embodiments of the present application are introduced in combination with the text and figures.

[0246] As shown in FIG. 4, a topology structure of a communication system in an A-IoT scenario is provided in the embodiments of the present application, taking a network device as a base station (BS) and a terminal device as a user equipment (UE) as an example. The BS can communicate with UE1, UE2 and UE3. UE1, UE2 and UE3 are intermediate UEs.

[0247] In the A-IoT, for the intermediate UEs of the topology structure, the BS controls the intermediate UEs to initiate R2D / D2R transmission. The control method for the intermediate UEs in the A-IoT scenario is proposed in the embodiments of the present application, to solve the problem of BS controlling the intermediate UEs, and to perform efficient allocation of time-frequency domain and external excitation resources.

[0248] The intermediate UE has the ability to integrate and process information / distribute resources as a convergence node, which is more efficient and has less signaling overhead on the Uu air interface. The intermediate UE has the ability to distribute R2D / D2R transmission time-frequency resources as a reader device, and the intermediate UE can initiate R2D / D2R transmission on the specified resource configuration according to the resource indication of the BS. In addition, the intermediate UE can aggregate the results of one or more rounds of inventory / command and then report them, reducing signaling overhead.

[0249] First, an example is given from the whole: the BS controls multiple intermediate UEs, and the BS coordinates / controls the time-frequency resources of multiple intermediate UEs, which needs to consider resource sharing and coexistence with traditional NR UL or DL UEs. The BS configures or allocates or indicates time-frequency resources for each UE reader through the Uu air interface, and the BS configures the control or data resources of R2D and D2R, and then the terminal device (UE reader) with environmental Internet of Things capability can directly initiate R2D transmission and control or schedule R2D / D2R communication.

[0250] The initial time-frequency resource configuration can be controlled and scheduled semi-statically through RRC or MAC CE signaling, and when the network load or traffic demand changes, the time-frequency resources can be dynamically controlled and scheduled through Group DCI signaling.

[0251] In the embodiments of the present application, new or enhanced RRC or MAC CE or Group DCI can be used to support semi-static and dynamic configuration of the following functions. First, the UE needs to report its capability to the gNB, and the gNB indicates the UE supporting A-IoT function and whether the UE has a CW device inside according to the reporting result. The UE supporting A-IoT function can provide A-IoT services as an intermediate UE, and the UE having a CW device inside means that the UE has the ability to generate a CW.

[0252] The gNB allocates or indicates appropriate time-frequency resources for the selected intermediate UE, and then the intermediate UE initiates R2D / D2R transmission. The resource configuration can be indicated to the intermediate UE by the gNB through layer 1 (L1) or layer 2 (L2) or layer 3 (L3) signaling. Among them, L1 is dynamic resource allocation, and L2 and L3 are static or semi-static resource allocation. The initial resource configuration can be controlled or scheduled semi-statically, for example, through RRC or MAC CE signaling; when the network load or traffic demand changes, dynamic resource control or scheduling can be used, for example, through Group DCI signaling.

[0253] As shown in FIG. 5, the embodiment of the present application provides a schematic diagram of semi-statically configuring resources of a network device, for example, semi-statically configuring resources of a gNB. Taking the interaction between the kth UE and the gNB as an example, the process mainly includes the following steps.

[0254] S01, the UE reports the capability of the UE to the gNB, and the capability of the UE includes: supporting A-IoT function, and whether the UE has a CW device inside.

[0255] S02, the gNB configures the time domain resource pool and the frequency domain resource pool for the UE with AIoT function in the cell according to the UE capability reporting result.

[0256] S03, the gNB sends RRC or MAC CE to the CW device.

[0257] If the UE k has no CW device inside, the gNB instructs the external CW device to configure the carrier excitation or the carrier for energy harvesting EH.

[0258] S04, the gNB performs initial time domain resource allocation and frequency domain resource allocation for the UE k .

[0259] The gNB uses the semi-static resource allocation mode, and the resource allocation remains unchanged within a certain time, but can be periodically adjusted as needed. For example, the length of the time can be 20 ms.

[0260] The gNB distinguishes the following two resource allocation modes: the gNB allocates resources to the intermediate UE; and the intermediate UE can autonomously select resources in the resource pool.

[0261] The gNB can allocate resources for the UE by RRC or MAC CE indication.

[0262] The resources allocated by the gNB can include time domain resources and frequency domain resources.

[0263] First, the time domain resource allocation is explained. The gNB can configure the time domain resource pool, and the gNB uses the bitmap to determine the starting symbol and length of the time slot.

[0264] For example, the RRC can define the time domain resource by indicating the starting symbol and the length of the allocated symbol. For example, the RRC signaling contains the starting symbol index and the symbol length.

[0265] The RRC can use the time domain resource allocation to indicate the resource allocation. The time domain resource allocation can contain multiple configurations of time domain resource allocation, and the base station can select a specific configuration by index. Each configuration item includes the starting symbol, the symbol length, and other related parameters.

[0266] Next, the frequency domain resource allocation is explained. The gNB can configure a frequency domain resource pool, and configure the frequency domain resource for a bandwidth part (BWP). A bitmap is used to indicate the allocation, and the resource block (RB) index information is a bitmap.

[0267] The RRC can indicate the frequency domain resource using a resource indication value (RIV), which indicates the starting resource block and the number of allocated resource blocks.

[0268] For example, RIV = N_RB x (S-1) + L-1;

[0269] Where N_RB is the total number of resource blocks in the system bandwidth, S is the starting resource block index, and L is the number of allocated resource blocks.

[0270] The RRC can predefine some frequency domain resource allocation configurations, and indicate the specific resource allocation through a configuration index. This way can reduce signaling overhead and improve resource allocation flexibility.

[0271] The RRC can use a frequency domain resource allocation table to indicate resource allocation. The frequency domain resource allocation table can contain multiple frequency domain resource allocation configurations, and the base station can select a specific configuration through an index.

[0272] S05, the gNB indicates the time domain resource and the frequency domain resource through RRC or MAC CE.

[0273] S06, UE with AIoT function k Make proximity judgment, UE with CW device inside k Configure carrier excitation, prepare to initiate R2D / D2R transmission according to the time-frequency domain resource indicated or allocated by the gNB.

[0274] S07, within the configured time-frequency resource, the UE k Initiate R2D transmission.

[0275] S08, if the UE has a CW device inside, within the configured time-frequency resource, the UE k Transmit CW excitation.

[0276] S09, if the UE has no CW device inside, within the configured time-frequency resource, the CW device transmits CW excitation.

[0277] S10, within the configured time-frequency resource, the UE k Initiate D2R transmission.

[0278] S11, the UE k Report one or more rounds of results through RRC / MAC CE.

[0279] For example, the result can include: the result of Inventory / Command / Sensors / Positioning, which contains Reader ID / Device ID / proximity determination result.

[0280] As shown in FIG. 6, the embodiment of the present application provides a schematic diagram of dynamic configuration of resources of a network device, for example, dynamic configuration of resources of a gNB. Taking the interaction of the kth UE with the gNB as an example, the main process includes the following steps:

[0281] S21, the UE reports the capability of the UE to the gNB, and the capability of the UE includes: supporting A-IoT function, and whether the UE has a CW device inside.

[0282] S22, the gNB configures the time domain resource pool and the frequency domain resource pool for the UE with AIoT function in the cell according to the UE capability reporting result.

[0283] S23, the gNB sends group DCI or DCI to the CW device.

[0284] If the UE k If there is no CW device inside, the gNB instructs the external CW device to configure the carrier excitation or configure the carrier for EH.

[0285] S24, the gNB dynamically adjusts or instructs the time-frequency resource according to the initial configuration and / or the result reported in the previous round or multiple rounds, or releases the current AIoT resource pool / configures a new resource pool according to other service requirements.

[0286] Among them, the gNB adopts the dynamic configuration of resources, and the resource allocation is dynamically adjusted according to the network status. It is suitable for the scene with high network load and large change.

[0287] The gNB can allocate resources for the UE through group DCI or DCI.

[0288] The resource allocated by the gNB can include: time domain resource allocation and frequency domain resource allocation.

[0289] First, the time domain resource allocation is explained. The gNB can configure the time domain resource pool, and the gNB uses Bitmap to determine the starting symbol and length of the time slot.

[0290] Optionally, the gNB defines the time domain resource by indicating the starting symbol and the length of the allocated symbol. For example, the base station can indicate that the resource allocation starts from the 0th symbol and lasts for 13 symbols.

[0291] Next, the frequency domain resource allocation is explained. The gNB can configure a frequency domain resource pool, configure the frequency domain resource for the bandwidth part (BWP), and indicate the allocation by using a bitmap. The RB index information is a bitmap.

[0292] Optionally, the RRC can use the RIV to indicate the starting resource block and the number of allocated resource blocks by using a value. For example, the device 2b can allocate a larger granularity of frequency domain resource.

[0293] The RIV = N_RB x (S-1) + L-1, where N_RB is the total number of resource blocks in the system bandwidth, S is the starting resource block index, and L is the number of allocated resource blocks.

[0294] S25, the gNB indicates the time domain resource and the frequency domain resource by group DCI or DCI.

[0295] S26, the UE with AIoT function k judges the proximity, and the UE has a CW inside k configures the carrier excitation, and prepares to initiate the R2D or D2R transmission according to the time-frequency domain resource indicated or allocated by the gNB.

[0296] S27, the UE k initiates the R2D transmission.

[0297] S28, if the UE has a CW inside, the UE k transmits the CW excitation.

[0298] S29, if the UE has no CW inside, the CW device transmits the CW excitation in the configured time-frequency resource.

[0299] S30, the UE k initiates the D2R transmission.

[0300] S31, reports one or more rounds of results by group UCI or ACK or NACK.

[0301] Next, the specific process of allocating the time domain resource and the frequency domain resource for the UE by the gNB in the above process is illustrated.

[0302] First, the downlink transmission process is explained from the perspective of the BS. The BS controls or indicates the mapping mode of the CW, the frequency domain, and the time domain of the intermediate UE with A-IoT capability and the CW device inside by semi-static or dynamic configuration of the resource.

[0303] The BS controls or indicates the frequency domain resource of the intermediate UE for R2D or D2R transmission, and the frequency domain resource of the CW for transmitting the excitation signal by using the following mapping modes:

[0304] Type 1: CW employs continuous frequency domain resource mapping, where CW and R2D or D2R employ different continuous frequency domain resources, and the starting RB is indicated, as well as the available RB resource pool.

[0305] Type 2: CW employs interleaved mapping, where CW is interleaved with the frequency domain resources used for R2D transmission, and the frequency domain resources of CW can be reused for D2R, and the starting RB is indicated, as well as the available RB resource pool.

[0306] Without limitation, interleaved mapping can be used for continuous frequency domain resources, or non-continuous frequency domain resources.

[0307] The BS indicates whether the CW transmitted by the intermediate UE is in the uplink frequency band of FDD or in the downlink frequency band of FDD, and indicates the mapping type, which can include continuous frequency domain mapping or non-continuous frequency domain mapping.

[0308] The BS indicates which deployment method is used for the CW transmitted by the intermediate UE and R2D or D2R transmission: 1) in-band; 2) guard band; 3) independent frequency band.

[0309] The BS indicates whether the CW transmitted by the intermediate UE has frequency hopping capability, and if it has frequency hopping capability, further indicates the frequency hopping offset.

[0310] The BS controls or indicates the time domain resources used by the intermediate UE for R2D or D2R transmission, and the time domain resources of the CW used for transmission of the excitation signal, using the following mapping methods:

[0311] Type A: CW employs continuous time domain resource mapping, where CW and R2D or D2R employ different time slots or symbols, and the starting time slot or symbol is indicated, as well as the duration.

[0312] Type B: CW employs non-continuous interleaved mapping, where CW is interleaved with the time domain resources used for R2D transmission, and the time domain resources of CW can be reused for D2R, and the starting time slot or symbol is indicated, as well as the duration.

[0313] The BS indicates whether the CW transmitted by the intermediate UE is periodically configured, or semi-persistently configured, or non-periodically configured.

[0314] In some embodiments of the present application, the intermediate UE reports to the BS on demand to request configuration of a time-domain resource pool (or a frequency-domain resource pool) of aperiodic trigger transmission CW, which is bound to a D2R representative use case (inventory / command / sensor / positioning), and the parameter is configured by high-layer RRC signaling. If the parameter is configured by the high layer, the intermediate UE is triggered by DCI to transmit the CW excitation signal in the configured time slot.

[0315] Next, the uplink transmission process is described from the perspective of the UE. The intermediate UE reports to the BS on demand the results of the inventory / command / sensor / positioning use case. The reporting can be for a specific A-IoT device or for multiple A-IoT devices under the service of an intermediate UE. The results can be after one round of aggregation or after multiple rounds of aggregation.

[0316] The BS configures a specific time slot period or semi-persistent for the intermediate UE to report the results.

[0317] Alternatively, the intermediate UE triggers aperiodic reporting on demand for separate aggregated results of different use cases, for example, using RRC, UCI, ACK, or NACK. For NACK results, the intermediate UE initiates one or more retransmissions in the configured time-frequency resources. If it still fails, the intermediate UE charges the failed A-IoT, for example, by using CW excitation or R2D transmission to charge it. Alternatively, the intermediate UE requests new or unoccupied time-frequency resources from the BS to reinitiate the command.

[0318] As shown in FIG. 7, the A-IoT frequency-domain resource pool provided by the embodiments of the present application is described.

[0319] The BS needs to configure frequency-domain resources for the intermediate UE, which can be allocated using a bitmap. The RB index information is a bitmap.

[0320] The BS needs to predefine or preconfigure the frequency-domain resource pool and indicate the resource pool through signaling and indicate which frequency-domain resources can be used for R2D transmission and which frequency-domain resources can be used for D2R transmission.

[0321] The frequency-domain resources can specifically include: the starting position of the frequency domain, the bandwidth, the frequency-domain resources of R2D transmission (starting position, bandwidth, and occupied RB number), the frequency-domain resources of D2R transmission (starting position, bandwidth, and occupied RB number), and configuration or indication of the allowed frequency shift amount or range.

[0322] Different bandwidth configurations correspond to different frequency resource pools and are bound to device types. The occupied bandwidth configured by the BS includes two guard bands and a communication band, which can be used for R2D transmission and D2R transmission.

[0323] For example: the occupied bandwidth of device 1 is 180 kHz bandwidth, and device 2b can have multiple bandwidth configurations, which can be configured according to different use cases (Inventory / Command / Sensors / Positioning).

[0324] The subcarrier spacing can be 15 kHz, and the bandwidth can be 180 kHz, 360 kHz, 1.08 MHz, or the subcarrier spacing can be 30 kHz, and the bandwidth can be 360 kHz, 720 kHz, 2.16 MHz.

[0325] D2R needs to distinguish between single sideband (SSB) or double sideband modulation (DSB) transmission, and the corresponding subcarrier and bandwidth configurations are different.

[0326] Specifically, in the A-IoT time domain resource pool, if the NR frame and the A-IoT frame multiplex the same frequency resource, the NR frame and the A-IoT frame need to be distinguished in the time domain. It can be configured as a periodic, semi-persistent or aperiodic frame or slot configuration through L3 or L2 or L1 signaling, and the position of the slot starting symbol and the symbol length can be determined by a bitmap.

[0327] As shown in FIG. 8a, when a semi-persistent frame slot configuration is used, in the initial stage, the gNB allocates a set of time domain resources to the intermediate UE. These resources remain unchanged in the next multiple scheduling periods. The intermediate UE uses these pre-allocated time domain resources for A-IoT control or data transmission in each scheduling period to reduce the signaling overhead of resource request and allocation before each transmission. If the business demand changes, the network can dynamically adjust or release these resources.

[0328] Determine the periodic time interval of time domain allocation, for example, resource allocation is performed every 20 ms.

[0329] Specify the time domain resources allocated in each scheduling period. A subframe contains multiple slots, and each slot can be further divided into multiple symbols.

[0330] Specify the length of time for which the resource allocation remains unchanged, for example, the resource allocation can remain unchanged for the next 10 scheduling periods.

[0331] As shown in FIG. 8b, in a non-periodic frame or time slot configuration, the intermediate UE sends an A-IoT transmission scheduling request to the BS according to actual needs; the base station dynamically allocates time domain resources according to current network load and service demand; the intermediate UE performs A-IoT control or data transmission in the received time domain resources; and the intermediate UE sends feedback information to the BS after completing one or more A-IoT transmissions, reporting the transmission status.

[0332] In some embodiments of the present application, a communication device is also provided, which includes a terminal device, and the terminal device includes:

[0333] a sending module configured to send first information to a network device, the first information being used to report whether the terminal device has an environmental Internet of Things capability and whether the terminal device has a capability of generating a carrier;
