[0004] A-IoT devices have limited communication capabilities, and their random access process needs to be triggered by a reader. When there are a large number of A-IoT devices that need to access, multiple A-IoT devices may respond to the reader to device (R2D) signal sent by the reader at the same time, resulting in collision. Therefore, in each random access period, multiple access rounds may be needed to enable A-IoT devices that have failed to access to continue to attempt access in subsequent rounds.

[0005] However, A-IoT devices that have completed access repeatedly attempt access, thereby affecting the access of other A-IoT devices that have not successfully accessed. SUMMARY

[0101] For the purpose of clearly describing the technical solutions of the embodiments of the present disclosure, the following briefly introduces some terms and technologies involved in the embodiments of the present disclosure:

[0102] 1. A-IoT device

[0103] An A-IoT device has no or limited energy storage capability, and can obtain energy from the environment through wind, light, pressure, wireless signals and other means, and has the characteristics of low power consumption, low cost and low complexity.

[0104] The 3rd generation partnership project (3GPP) divides A-IoT devices into the following three categories according to whether the A-IoT devices have energy storage capability and independent signal generation capability:

[0105] Type A, the A-IoT device of this type has energy storage capability and no independent signal generation capability, and can perform signal transmission through backscatter.

[0106] Type B, the A-IoT device of this type has energy storage capability and no independent signal generation capability, and can perform signal transmission through backscatter, and the stored energy can be used to amplify the power of the backscatter signal.

[0107] Type C, the A-IoT device of this type has energy storage capability and independent signal generation capability, and can use radio frequency devices for signal transmission.

[0108] 2. Backscatter communication

[0109] A backscatter communication system is composed of an excitation signal source and a signal reflection device, and is generally composed of a reader and a reflection tag. The reader can generate an excitation signal, and the reflection tag is composed of a device that can reflect a radio frequency signal. The reader sends a radio frequency signal (which can be referred to as an excitation signal) to the reflection tag, and the excitation signal forms a reflected echo, i.e., a backscatter signal, after reaching the surface of the reflection tag antenna. By changing the load impedance of the reflection tag antenna, the tag can control the amplitude, waveform, frequency, etc. of the backscatter signal, thereby modulating information into the backscatter signal. The reader receives and reads the backscatter signal from the reflection tag, and thus obtains the information transmitted by the reflection tag.

[0110] The relationship between the backscattering signal and the excitation signal can satisfy the following formula: S out = S in × Γ i

[0111] Wherein, S out is the backscattering signal, S in is the excitation signal, and Γ i is the reflection coefficient. When the reflection coefficient is a first reflection coefficient, the energy of the excitation signal is completely absorbed by the tag antenna; when the reflection coefficient is a second reflection coefficient, the excitation signal is completely reflected; and when the reflection coefficient is a third reflection coefficient, the excitation signal is partially absorbed and partially reflected.

[0112] 3, Receiver architecture of A-IoT device

[0113] For the A-IoT device, since its receiver structure is extremely simple and only includes the receiver components shown in FIG. 1A, FIG. 1B or FIG. 1C, the A-IoT device cannot complete the reception and processing of various configuration parameters (such as random access configuration parameters and paging configuration parameters).

[0114] 4, Relay technology

[0115] The base station configures the relay transmission resource, and the relay further schedules the data transmission between the relay itself and the terminal; for the repeater network, the repeater directly receives the signal of the base station for direct amplification and forwarding. Examples:

[0116] (1) The relay adopts time division duplex (TDD) spectrum and must comply with strict TDD subframe configuration and its time slot timing relationship; (2) The main role of the relay is to improve the system capacity, especially the performance of the terminal at the edge of the cell; (3) The relay includes L1 relay, L2 relay and L3 relay, wherein the L1 relay is an amplification relay, which is similar to the traditional repeater function and realizes amplification and forwarding of physical signals; the L2 relay is a decoding relay, which realizes signal forwarding on the basis of decoding the signal, and the L2 relay has the function of partial resource allocation; the L3 relay has a complete network protocol layer, that is, it can realize the full function of the base station.

[0117] 5, Integrated access and backhaul (IAB) technology

[0118] In 5G technology, new types of network nodes are considered to increase the flexibility of network deployment for mobile operators. For example, IAB is introduced in 3GPP Release 16 and enhanced in Release 17 as a new type of network node that does not require a wired backhaul. Another type of network node is a radio frequency (RF) repeater, which simply amplifies and forwards the received RF signals. RF repeaters have been widely deployed in 2G, 3G, and 4G to supplement the coverage provided by regular full-stack cells.

[0119] For example, 5G IAB technology is shown in FIG. 2. By uniformly designing the control channels, data channels, and access procedures of access links and backhaul links, access and backhaul links are multiplexed in time, frequency, and spatial domains, mainly to improve the coverage performance of new radio (NR).

[0120] For example, (1) To support TDD systems and some potential functions that require network synchronization, time synchronization between IAB nodes is necessary, and at least symbol-level synchronization is maintained between IAB nodes; (2) Downlink (DL) IAB node transmissions (i.e., transmissions from an IAB node to an IAB child node served by the IAB node on a backhaul link and transmissions from an IAB node to a terminal served by the IAB node on an access link) should be scheduled by the IAB node itself. Uplink (UL) IAB transmissions (transmissions from an IAB node to its IAB parent node or IAB donor node on a backhaul link) should be scheduled by the IAB parent node or IAB donor node.

[0121] 6、Network controlled repeater (NCR)

[0122] As shown in FIG. 3, an NCR includes an NCR mobile termination (MT) and an NCR forwarding. Among them, the NCR-MT is defined as a functional entity that communicates with a network device via a control link to achieve control information exchange. The control link is based on the NR Uu interface. The NCR forwarding is defined as a functional entity that performs amplification and forwarding of UL / DL RF signals between a network device and a terminal via a backhaul link and an access link. The NCR controls the behavior of the NCR forwarding according to the control information received from the network device. In addition, at least one carrier of the NCR-MT should work in the frequency band of the NCR forwarding.

[0123] 7、Other terms

[0124] The term "and / or" in the embodiments of the present disclosure describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B can represent the following three cases: A exists alone, A and B exist together, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after it.

[0125] The term "at least one" in the embodiments of the present disclosure means one or more, "more" means two or more, and other quantifiers are similar. For example, at least one of a, b, or c can mean a, b, c, a-b, a-c, b-c, or a-b-c, where a, b, and c can be single or multiple.

[0126] The terms "first", "second", and the like in the embodiments of the present disclosure are only used for description and distinction of the described objects, and do not have order difference, nor represent special limitation of the number of objects in the embodiments of the present disclosure, and cannot constitute any limitation on the embodiments of the present disclosure. The description of "first dynamic signaling" and "second dynamic signaling" is only used to distinguish different dynamic signaling, and does not represent the difference in size, priority or importance of the two dynamic signaling.

[0127] In order to better understand the method provided by the embodiments of the present disclosure, the application scenario of the embodiments of the present disclosure will be described first.

[0128] FIG. 4 is a schematic diagram of an application scenario provided by the embodiments of the present disclosure, as shown in FIG. 4, including a network device, an intermediate node, and an A-IoT device. The intermediate node can send A-IoT device data or signals to the A-IoT device; the A-IoT device receives the A-IoT device data or signals sent by the intermediate node and sends corresponding response signals; the intermediate node can receive the response signals sent by the A-IoT device; and the network device and the intermediate node can communicate through a Uu interface.

[0129] The intermediate node can be a repeater, an integrated access and backhaul (IAB) node, a terminal, etc. with A-IoT communication capability.

[0130] It should be noted that the above application scenario and the number of devices in the application scenario are only examples, for example, the number of A-IoT devices can also be other values, and the present disclosure does not limit the number of devices in the application scenario.

[0131] The technical solutions provided by the embodiments of the present disclosure can be applied to various systems. For example, the applicable systems can be a long term evolution (LTE) system, an LTE frequency division duplex (FDD) system, an LTE time division duplex (TDD) system, a long term evolution advanced (LTE-A) system, a universal mobile system (UMTS), a worldwide interoperability for microwave access (WiMAX) system, a 5G NR system and its evolution communication system, a 6G (sixth generation mobile communication technology) system, and the like. The various systems can include terminals and network devices. The system can also include a core network part, such as an evolved packet system (EPC), a 5G core network (5GC), and the like.

[0132] The network device related to the embodiments of the present disclosure can be a base station, which can include a plurality of cells serving terminals. According to different application occasions, the base station can also be called an access point, or can be a device in an access network that communicates with wireless terminals through one or more sectors over an air interface, or other names. The network device can be used to exchange received air frames and Internet Protocol (IP) packets as a router between the wireless terminal and the rest of the access network, which can include an Internet Protocol (IP) communication network. The network device can also coordinate the management of the properties of the air interface. For example, the network device related to the embodiments of the present disclosure can be an evolved network device (eNB or e-NodeB) in a long term evolution (LTE) system, a 5G base station (gNB) in a 5G network architecture (next generation system), and the like, and can also be a home evolved node B (HeNB), a relay node, a femto, a pico, a network test device, and the like, which are not limited in the embodiments of the present disclosure. In some network structures, the network device can include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit can also be arranged geographically apart.

[0133] The terminal involved in the embodiments of the present disclosure can refer to a device that provides voice and / or data connectivity to a user, a handheld device with wireless connection function, or other processing devices connected to a wireless modem, etc. In different systems, the name of the terminal can also be different, for example, in the 5G system or the 6G system, the terminal can be called user equipment (UE). The wireless terminal can be a USB storage device, other personal computer memory devices and a dongle, and can also communicate with one or more core networks (CN) through a radio access network (RAN), and the wireless terminal can be a mobile terminal, such as a mobile phone (or called "cellular" phone) and a computer with a mobile terminal, for example, it can be a portable, pocket, handheld, built-in computer or vehicle-mounted mobile device, which exchanges voice and / or data with a radio access network. For example, personal communication service (PCS) phones, cordless phones, session initiated protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), personal computers, tablet computers, machine-type communication (MTC) terminals and the like. The wireless terminal can also be called a system, a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, a user device, and a wireless access device and a router / modem that meet the limitations of the present definition, etc. The embodiments of the present disclosure are not limited.

[0134] In the related art, a network device can directly schedule a terminal to perform data transmission. Unlike traditional LTE and NR interactive terminals, an A-IoT device is a response device based on backscattering / generating signals. The response signal from the A-IoT device depends on the excitation signal and the push notification from the network device or an intermediate node. The network device or the terminal as an intermediate node can send an "interrogation" signal to the A-IoT device. The A-IoT device will respond to the interrogation signal based on the preconfigured / preprogrammed functions of the carrier.

[0135] For A-IoT devices, if the above forwarding scheme, IAB scheme or NCR scheme is directly applied to an A-IoT network, the following problems exist:

[0136] (1) A-IoT devices are energy-constrained and cannot handle complex transmissions and longer transmissions, and cannot maintain synchronization with the network device. (2) When the terminal is an intermediate node, how does the network device schedule the terminal as an intermediate node to ensure that the random access and data transmission between the terminal and the A-IoT device are completely controlled by the network device, and the terminal does not perform resource allocation and transmission link parameter determination; and how to design the control signaling of the network device to schedule the transmission of the terminal and the A-IoT device.

[0137] Embodiments of the present disclosure provide a communication method and device and a storage medium. A first device can communicate with an Internet of Things device based on transmission resources and / or configuration information configured by a network device and a core network device, or the first device can communicate with the Internet of Things device based on transmission resources and / or configuration information configured by itself. The method and device are based on the same application concept. Since the principles of solving problems are similar, the implementation of the device and the method can be mutually referred to, and the repeated parts will not be described again.

[0157] (5) Time parameter.

[0158] The time parameter can include a first time unit and / or a second time unit.

[0160] The second time unit is a time unit at which the IoT device sends information and / or data.

[0161] In the embodiments of the present disclosure, the time unit can include at least one of a symbol, a slot, a subframe, or a radio frame.

[0162] The transmission resource is described in detail below.

[0163] The transmission resource can be predefined or configured in advance to the first device by a network device through radio resource control (RRC) signaling.

[0164] The network device can configure multiple transmission resources in advance for the first device through RRC signaling, and then indicate the first device to transmit information and / or data with the IoT device on one of the multiple transmission resources through indication information.

[0165] The network device can also configure one transmission resource in advance for the first device through RRC signaling, and then activate the transmission resource through indication information (for example, the first information included in the PDCCH only includes indication information), so that the first device can transmit information and / or data with the IoT device on the transmission resource.

[0166] In a possible implementation, the transmission resource can include a first resource and / or a second resource, wherein the second resource can be a resource used by the first device to send information to the Internet of Things device; and the third resource can be a resource used by the first device to receive information sent by the Internet of Things device.

[0167] The first resource can include at least one of a time domain resource, a frequency domain resource, or a space domain resource.

[0171] The downlink spectrum resource can be a resource used by the network device to send information to the first device.

[0172] The flexible spectrum resource can include the uplink spectrum resource and / or the downlink spectrum resource.

[0173] For example, the first resource can be a physical downlink shared channel (PDSCH) resource or a physical uplink shared channel (PUSCH) resource; and the second resource can be a PDSCH resource or a PUSCH resource.

[0174] The PDSCH resource can be a resource used to transmit a PDSCH, and the PUSCH resource can be a resource used to transmit a PUSCH.

[0175] In a possible implementation, the first device can configure the first information by itself, or receive the first information from other devices (for example, a network device or a core network device). For example, the first information can be carried in first dynamic signaling, RRC signaling, a data channel, or core network signaling. The first dynamic signaling includes at least one of the following: first downlink control information (DCI), first media access control-control element (MAC CE), and a physical downlink control channel (PDCCH). The data channel includes a PDSCH.

[0177] In the embodiments of the present disclosure, the uplink data can refer to data sent by the first device to the network device, and the downlink data can refer to data sent by the network device to the first device.

[0178] When the first information only includes indication information, the first DCI can be defined as signaling that does not need scheduling configuration information.

[0179] The first DCI can be a predefined DCI, or can be multiplexed with a DCI in an existing protocol, for example, an NR DCI.

[0181] For example, when the first information only includes configuration information, the first information can be carried in a PDSCH; when the first information only includes indication information, the first information can be carried in first DCI, first MAC CE, or a PDCCH.

[0182] For another example, when the first information only includes indication information, and the indication information indicates the first resource, the first information can be carried in DCI1; when the first information only includes indication information, and the indication information indicates the second resource, the first information can be carried in DCI2.

[0183] In another example, when the first information only includes the indication information and the indication information indicates the first resource, the first information can be carried in the MAC CE 1; when the first information only includes the indication information and the indication information indicates the second resource, the first information can be carried in the MAC CE 2.

[0184] In another example, when the first information only includes the indication information and the indication information indicates the first resource, the first information can be carried in the DCI 1; when the first information only includes the indication information and the indication information indicates the second resource, the first information can be carried in the MAC CE 1. Alternatively, when the first information only includes the indication information and the indication information indicates the first resource, the first information can be carried in the MAC CE 1; when the first information only includes the indication information and the indication information indicates the second resource, the first information can be carried in the DCI 1.

[0187] When the first information includes the indication information, the first device can communicate with the Internet of Things device on the transmission resource indicated by the indication information.

[0188] In an example, when the transmission resource indicated by the indication information is the first resource, the first device can send information to the Internet of Things device on the first resource. When the transmission resource indicated by the indication information is the second resource, the first device can receive information sent by the Internet of Things device on the second resource. When the transmission resource indicated by the indication information is the first resource and the second resource, the first device can send information to the Internet of Things device on the first resource, and receive information sent by the Internet of Things device on the second resource.

[0189] When the first information includes the configuration information and the indication information, the transmission resource indicated by the indication information can belong to the channel resource included in the configuration information. When the first device communicates with the Internet of Things device on the transmission resource indicated by the indication information, the channel parameter included in the configuration information can also be used.
