[0042] In embodiments of the present invention, the term "and / or" describes the association relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0043] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0044] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0045] The embodiments of the present application provide a communication method and apparatus for enabling network devices and IoT devices to communicate via a relay device.

[0046] Among them, the method and the device are based on the same application concept. Since the principles of solving problems by the method and the device are similar, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0047] The technical solutions provided in the embodiments of the present application can be applicable to a variety of systems. For example, applicable systems may be long term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, long term evolution advanced (LTE-A) systems, universal mobile telecommunication systems (UMTS), worldwide interoperability for microwave access (WiMAX) systems, 5G new radio (NR) systems and their evolved communication systems, etc. These various systems may include terminal devices and network devices. The system may also include a core network part, such as an evolved packet system (EPS), a 5G system (5GS), etc.

[0048] Figure 1 This is a schematic diagram of the structure of a communication system provided in an embodiment of the present application. Figure 1 As shown, the communication system includes: network equipment, relay equipment, and Internet of Things equipment.

[0049] The network device involved in the embodiments of the present application may be a base station, which may include multiple cells providing services to the terminal. Depending on the specific application scenario, the base station may also be called an access point, or may be a device in the access network that communicates with the wireless terminal device through one or more sectors on the air interface, or other names. The network device may be used to interchange received air frames with Internet Protocol (IP) packets, acting as a router between the wireless terminal device and the rest of the access network, wherein the rest of the access network may include an Internet Protocol (IP) communication network. The network device may also coordinate the attribute management of the air interface. For example, the network device involved in the embodiments of the present application may be an evolutionary network device (eNB or e-NodeB) in a long term evolution (LTE) system, a 5G base station (gNB) in a next generation system, etc., or a home evolved Node B (HeNB), a relay node, a femto, a pico base station (pico), a network test device, etc., which is not limited in the embodiments of the present application. In some network structures, network devices may include centralized unit (CU) nodes and distributed unit (DU) nodes, and the centralized unit and the distributed unit may also be arranged geographically separately.

[0050] The relay equipment involved in the embodiments of the present application may be a repeater, a repeater, an integrated access and backhaul node (IAB), etc. Among them, the repeater is a simple relay technology that directly amplifies and forwards the radio frequency signal and cannot distinguish between signals, interference and noise, so it is only used to improve the coverage range. The repeater has baseband signal processing capabilities, which can not only amplify the signal, but also suppress interference and noise, or, if the repeater is an LTE repeater, the repeater can be regarded as an independent base station. In IAB technology, there are two types: IAB master node (IAB-donor) and IAB node. The IAB master node is equivalent to the host base station, which is connected to the core network through a wired manner and performs centralized resource, topology and routing management for the IAB topology; the IAB-node is a micro station, deployed in areas that are not covered by the macro station, and does not require optical fiber or microwave for backhaul, but directly backhauls through 5G millimeter waves.

[0051] In one possible implementation, the relay device may be a terminal device, which may be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connection capabilities, or other processing devices connected to a wireless modem. In different systems, the name of the terminal device may also be different. For example, in a 5G system, the terminal device may be called a user equipment (UE). A wireless terminal device may be a USB storage device, other personal computer memory devices, and a dongle. It may also communicate with one or more core networks (CN) via a radio access network (RAN). A wireless terminal device may be a mobile terminal device, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal device. For example, it may be a portable, pocket-sized, handheld, computer-built-in, or vehicle-mounted mobile device that 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) terminal devices, etc. Wireless terminal devices may also be referred to as systems, subscriber units, subscriber stations, mobile stations, mobile stations, remote stations, access points, remote terminal devices, access terminals, user terminals, user agents, user devices, and wireless access points and routers / modems that meet the limitations of this definition, but are not limited in the embodiments of the present application.

[0052] The IoT devices involved in the embodiments of the present application may be Ambient Internet of Things (A-IoT) devices, or may be any other type of IoT devices. A-IoT devices are low-end IoT devices with low complexity, low cost, and low power consumption. Among them, A-IoT devices are divided into three types of devices, Device A, Device B, and Device C, based on whether they have energy storage capabilities and independent signal generation capabilities. Device A type A-IoT devices have no energy storage capabilities, no independent signal generation capabilities, and transmit signals through backscattering; Device B type A-IoT devices have energy storage capabilities, no independent signal generation capabilities, and transmit signals through backscattering, and the stored energy can be used to amplify the power of the backscattered signal; Device C type A-IoT devices have energy storage capabilities, have independent signal generation capabilities, and use radio frequency devices for signal transmission. The IoT devices involved in the embodiments of the present application may be any of the above-mentioned A-IoT devices, and are not limited in the embodiments of the present application.

[0053] exist Figure 1 In the system architecture shown, A-IoT devices have low power consumption, low complexity, and no or limited power supply. Therefore, their communication range may be limited in some scenarios. To increase the communication range of A-IoT devices, consider using relay devices to assist in A-IoT data transmission, thereby extending the communication range of A-IoT devices.

[0054] Specifically, an A-IoT device can transmit data to a relay device, which then relays the data or other data including the data to the network device. Alternatively, a network device can transmit data to a relay device, which then relays the data to the A-IoT device, thereby increasing the communication range of the A-IoT device.

[0055] However, there is currently no Figure 1 The system structure shown includes solutions for data content, data structure, transmission resource configuration method and other related contents during the data transmission process.

[0056] In view of this, the present application provides a communication method, which improves the specific process and specific configuration of network devices and IoT devices communicating through relay devices by providing multiple implementation methods of transmission resources and / or carried content of multiple information exchanged between network devices and IoT devices when communicating through relay devices, thereby realizing the function of network devices and IoT devices communicating through relay devices and improving the communication distance of IoT devices.

[0057] The following is based on Figure 1 The following scenarios are used to describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems through specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0058] Figure 2 This is a flow chart of a communication method provided in an embodiment of the present application. Figure 2 As shown, the method includes:

[0059] S201: The network device sends third information to the relay device.

[0060] Correspondingly, the relay device receives the third information sent by the network device.

[0061] The third information is used to instruct the relay device to send the second information to the IoT device, and the second information is used to instruct the IoT device to send the first information to the relay device.

[0062] In one possible implementation, the third information may indicate the transmission resources for the second information and / or the content carried by the second information. For example, if the third information indicates the transmission resources for the second information, the third information may indicate the configuration of at least one of the time domain resources, frequency domain resources, spatial domain resources, code domain resources, modulation parameters, and sequences used by the relay device to transmit the second information. If the third information indicates the content carried by the second information, the third information may indicate that the second information transmitted by the relay device carries instruction information required to instruct the IoT device to perform random access, or indicates that the second information carries query request information for the network device to query information about the IoT device, or indicates that the second information carries perception information collection instruction information for the network device to collect perception information of the IoT device. In this implementation, the transmission resources for the first information and / or the content carried by the first information may be determined by the IoT device based on the second information, or may be determined by the IoT device itself, or may be predefined by the protocol. Accordingly, the second information may indicate the transmission resources for the first information and / or the content carried by the first information, or may be used solely to trigger the IoT device to transmit the first information to the relay device.

[0063] In another possible implementation, the third information may indicate the transmission resources of the second information and / or the content carried by the second information, as well as the transmission resources of the first information and / or the content carried by the first information. For example, the third information may indicate the configuration of at least one of the time domain resources, frequency domain resources, spatial domain resources, and code domain resources used by the relay device to send the second information, and may indicate that the second information carries the transmission resources of the first information and / or the content carried by the first information, so that after receiving the second information, the IoT device can determine the transmission resources used to send the first information and / or the content carried by the first information based on the second information.

[0064] In another possible implementation, the third information is used only to trigger the relay device to send the second information to the IoT device. In this implementation, the transmission resources of the second information and / or the content carried by the second information can be determined by the relay device itself or predefined by the protocol. Accordingly, the second information can indicate the transmission resources of the first information and / or the content carried by the first information, or it can be used only to trigger the IoT device to send the first information to the relay device.

[0065] S202: The relay device sends second information to the IoT device.

[0066] Correspondingly, the IoT device receives the second information sent by the relay device.

[0067] The second information is used to instruct the Internet of Things device to send the first information to the relay device.

[0068] The signal carrying the first information can be a backscattered signal of the signal carrying the second information. That is, the signal carrying the first information transmitted by the IoT device is a backscattered signal generated based on the signal carrying the second information. Alternatively, the first information is generated by the IoT device itself, and the second information is used only to trigger the IoT device to transmit the first information to the relay device.

[0069] Optionally, the second information may also indicate the transmission resources of the first information, and / or the content carried by the first information. For example, if the second information can indicate the transmission resources of the first information, the second information may indicate the configuration of at least one of the time domain resources, frequency domain resources, spatial domain resources, code domain resources, modulation parameters, and sequences used by the IoT device to send the first information. If the second information can indicate the content carried by the first information, the second information may indicate that the first information sent by the IoT device carries relevant information of the random access process of the IoT device, or indicates that the first information carries query response information of the IoT device in response to the query request information of the network device, or indicates that the first information carries the perception information required to be reported by the IoT device in response to the perception information collection indication information of the network device, etc.

[0070] In the above steps S201 to S202, only the content of the transmission link in which the network device is the transmitter and the IoT device is the receiver is described. Optionally, the communication method can also include the content of the reception link in which the IoT device is the transmitter and the network device is the receiver, as shown in the following steps S203 to S204.

[0071] S203. The IoT device sends first information to the relay device.

[0072] Correspondingly, the relay device receives the first information sent by the IoT device.

[0073] The first information is response information to the second information. For example, when the second information indicates that the first information sent by the IoT device carries relevant information about the random access process of the IoT device, the first information carries relevant information about the random access process of the IoT device; when the second information indicates that the first information carries query response information of the IoT device in response to the query request information of the network device, the first information carries the query response information; when the second information indicates that the first information carries the perception information required to be reported by the IoT device in response to the perception information collection indication information of the network device, the first information carries the corresponding perception information obtained by the IoT device, etc.

[0074] The signal carrying the first information may be a backscattered signal of the signal carrying the second information. That is, the signal carrying the first information transmitted by the IoT device is a backscattered signal generated based on the signal carrying the second information. Alternatively, the first information is generated by the IoT device itself, and the IoT device transmits the first information to the relay device in response to a trigger from the second information.

[0075] Optionally, the transmission resources of the first information and / or the content carried by the first information may be indicated by the second information. For example, the second information may carry the transmission resources of the first information and / or the content carried by the first information. The transmission resources of the first information and / or the content carried by the first information may be obtained by the relay device based on third information received from the network device, may be determined by the relay device itself, or may be predefined by the protocol.

[0076] Optionally, the transmission resource of the first information and / or the content carried by the first information may be predefined by the protocol or determined by the IoT device itself. If the transmission resource of the first information and / or the content carried by the first information are determined by the IoT device itself, the IoT device may determine the transmission resource of the first information and / or the content carried by the first information by calculating the parameters carried by the second information.

[0077] S204: The relay device sends fourth information to the network device.

[0078] Correspondingly, the network device receives the fourth information sent by the relay device.

[0079] The fourth information includes the content carried by the first information, and is used by the relay device to forward the content carried by the first information to the network device.

[0080] The signal carrying the fourth information can be a backscattered signal of the signal carrying the third information. That is, the signal carrying the fourth information transmitted by the relay device is a backscattered signal generated based on the signal carrying the third information received by the relay device from the network device. Alternatively, the fourth information is generated by the relay device itself, and the IoT device transmits the fourth information to the network in response to a trigger of the third information and / or the first information.

[0081] Optionally, the transmission resource of the fourth information may be determined based on the third information, or may be predefined by a protocol.

[0082] When the transmission resource of the fourth information is determined based on the third information, the third information may include content indicating the transmission resource of the fourth information, for example, it may include a configuration indicating at least one of the time domain resources, frequency domain resources, spatial domain resources, code domain resources, modulation parameters, and sequence used to transmit the fourth information. For example, the third information may include the configuration of the transmission resource of the fourth information; or the third information may include parameters for calculating the transmission resource of the fourth information, and the relay device may calculate the transmission resource configuration of the fourth information based on the parameters.

[0083] The communication method provided in the embodiment of the present application improves the specific process and specific configuration of communication between network devices and Internet of Things devices through relay devices by providing multiple implementation methods of the transmission resources and / or carried content of the first information, second information, third information, and fourth information involved in communication between network devices and Internet of Things devices through relay devices, thereby realizing the function of network devices and Internet of Things devices communicating through relay devices and improving the communication distance of Internet of Things devices.

[0084] The resource configuration and / or carried content of the first information, second information, third information, and fourth information mentioned above are introduced in detail below.

[0085] First, let’s introduce the first and second information:

[0086] The first information is information sent by the IoT device to the relay device, and the second information is information sent by the relay device to the IoT device. The first information can be a response to the second information, that is, after the relay device sends the second information to the IoT device, the IoT device responds to the second information by sending the first information to the relay device.

[0087] The link for transmitting the first information and the second information is the first transmission link between the relay device and the IoT device. On the first transmission link, the first information and the second information can be transmitted by a waveform based on any one of modulations such as On-Off Keying (OOK), Frequency Shift Keying (FSK), Phase Shift Keying (PSK), Orthogonal Frequency-Division Multiplexing (OFDM), etc. For example, the first information and the second information can be transmitted by an OOK waveform based on OFDM modulation, an FSK waveform based on OFDM modulation, a PSK waveform based on OFDM modulation, an OOK waveform based on OFDM single carrier modulation, etc. Among them, the waveforms for transmitting the first information and the second information can be the same or different. For example, the first information can be transmitted by the first waveform, and the second information can be transmitted by the second waveform. For example, the first information can be transmitted by an OOK modulated waveform, and the second information can be transmitted by an FSK modulated waveform, etc.

[0088] Furthermore, the OOK waveform can be seen as one of the implementation methods of ASK, that is, using ON-OFF to identify information bit 0 and information bit 1; further, 4 amplitudes can be used to identify bit00, bit01, bit11, and bit 10 respectively.

[0089] Furthermore, based on the FSK waveform, frequency 1 can be used to identify bit 0, and frequency 2 can be used to identify bit 1; further, four frequencies can be used to identify bit 00, bit 01, bit 10, and bit 11 respectively.

[0090] Furthermore, based on the PSK waveform, phase 1 can be used to identify bit 0, and phase 2 can be used to identify bit 1; further, four phases can be used to identify bit 00, bit 01, bit 10, and bit 11 respectively.

[0091] The OOK waveform based on OFDM modulation can be to modulate the information through OFDM first and then perform OOK modulation; the waveforms of FSK and PSK based on OFDM modulation have similar principles and will not be repeated here.

[0092] The resource configuration and / or carried content of the first information may be predefined by the protocol, or determined based on the resource configuration information and / or carried content of the first information indicated in the second information (for example, the second information includes the resource configuration information and / or carried content of the first information, or includes information indicating the resource configuration information and / or carried content of the first information), or may be calculated by the IoT device based on the first target parameter.

[0093] When the resource configuration and / or content carried by the first information is determined based on the resource configuration information and / or content carried by the first information indicated in the second information, the resource configuration information and / or content carried by the first information may be indicated by the third information sent by the network device to the relay device. The relay device generates or obtains the second information indicating the resource configuration and / or content carried by the first information based on the resource configuration information and / or content carried by the first information indicated by the third information, and indicates the resource configuration of the first information through the second information. For example, after receiving the third information, the relay device can demodulate and decode the third information to obtain the resource configuration information and / or content carried by the first information, and indicate the resource configuration information and / or content carried by the first information to the IoT device through the second information; or, after receiving the third information, the relay device can directly forward the third information according to the signal format of the information carried by the relay node. The forwarded third information is the second information that carries the resource configuration information and / or content carried by the first information.

[0094] When the resource configuration and / or content carried in the first information is calculated based on the first target parameter, the first target parameter may be included in the second information or preset in the IoT device. For example, the first target parameter may be determined based on an identifier of the IoT device and a mapping relationship between the identifier and the resource configuration information and / or content carried in the first information.

[0095] The resource configuration and / or carried content of the second information may be predefined by the protocol (for example, pre-agreed by the network device and the relay device, or pre-configured by the core network, etc.), or determined based on the resource configuration information and / or carried content of the second information indicated in the third information (for example, the third information includes the resource configuration information and / or carried content of the second information, or includes information indicating the resource configuration information and / or carried content of the second information), or may be calculated by the relay device based on the second target parameter.

[0096] When the resource configuration and / or carried content of the second information is determined based on the resource configuration information and / or carried content of the second information indicated in the third information, the resource configuration information and / or carried content of the second information may be included in the third information sent by the network device to the relay device, or the information indicating the resource configuration information of the second information and / or carried content may be included in the third information sent by the network device to the relay device.

[0097] When the resource configuration and / or carried content of the second information is calculated based on the second target parameter, the second target parameter may be included in the third information or preset in the relay device. For example, the second target parameter may be determined based on an identifier of the relay device and a mapping relationship between the identifier and the resource configuration and / or carried content of the second information.

[0098] Optionally, the resource configuration of the second information may be based on network device scheduling. In this implementation, the resource configuration of the second information may be determined based on the scheduling of the data channel of the network device, for example, the second information may be transmitted on the resources of the control channel; the resource configuration of the second information may also be determined based on the scheduling of the signal of the network device, for example, the second information may be transmitted through the resources of the reference signal, etc. In this case, the resource configuration of the second information may be dynamically allocated by the network device, or allocated by semi-persistent transmission, or may also be allocated by periodic transmission, etc. For example, the network device may dynamically allocate the resource configuration of the second information through L1 signaling or L2 signaling carried by at least one of the physical uplink control channel (PUCCH), physical downlink control channel (PDCCH), physical uplink shared channel (PUSCH), and physical downlink shared channel (PDSCH) of the network device. For another example, the network device may configure the resource configuration of the second information through semi-persistent transmission and trigger the sending of the second signal through the physical downlink control channel.

[0099] Among them, the content carried in the second information may include at least one of the following: excitation signal, energy collection signal, energy storage information, information collection indication information, reference signal sending indication information, synchronization information, timing information, grouping information, function classification information, application scenario information, priority information, access parameter configuration and / or information, paging parameter configuration and / or information, base station information, Internet of Things device information, Internet of Things device grouping information, activation / deactivation signaling, threshold for Internet of Things device reflection or transmission signal, ACK confirmation information, modulation method, coding method, data packet size, data packet transmission time, reflection coefficient, etc.

[0100] Optionally, the first information may be response information to the second information, or forwarded second information, or forwarded third information. The content carried in the first information may include at least one of the following: IoT device information and parameters, ACK confirmation information, and data / information / signals sent by the IoT device. The IoT device information and parameters may include an IoT device identifier and a group identifier of the IoT device; the data / information / signals sent by the IoT device may include uplink transmission data sent by the IoT device (e.g., sensor data sensed by the IoT device's sensors, reference signals sent by the IoT device, and other information transmitted by the IoT device).

[0101] The third and fourth information are introduced below:

[0102] The third information is information sent by the network device to the relay device, and the fourth information is information sent by the relay device to the network device. The fourth information can be a response to the third information, can be the same as the first information, or can be a response to the second information. Optionally, the signal carrying the fourth information can be a backscattered signal of the signal carrying the third information, or can be a signal sent directly from the relay device to the network device. It should be understood that the backscattered signal of the signal carrying the third information can be the same as the backscattered signal of the signal carrying the second information, or can be a different signal.

[0103] The link for transmitting the third information and the fourth information is a second transmission link between the network device and the relay device. On this second transmission link, the third information and the fourth information can be transmitted via an OFDM-based waveform or an OFDM-based single-carrier waveform. For example, the third information and the fourth information can be transmitted via an OFDM-based waveform or an OFDM-based single-carrier waveform; alternatively, the third information can be transmitted via an OFDM-based waveform, and the fourth information can be transmitted via an OFDM-based single-carrier waveform; alternatively, the fourth information can be transmitted via an OFDM-based waveform, and the third information can be transmitted via an OFDM-based single-carrier waveform.

[0104] Exemplarily, the network device may transmit the third information on an Xn interface (e.g., an X2 interface), or transmit the third information on a Uu interface. The physical layer signal carrying the third information may be, for example, at least one of a data signal, a control signal, and a reference signal. The signaling carrying the third information may be, for example, at least one of radio resource control signaling (RRC), media access control signaling (MAC), physical layer signaling, a broadcast message, and a reference signal. The physical layer channel carrying the third information may be, for example, at least one of a PDCCH, a PDSCH, a broadcast channel, and a channel where a reference signal is located.

[0105] Exemplarily, the network device may receive the fourth information on an Xn interface (e.g., an X2 interface), or receive a physical layer channel carrying the fourth information on a Uu interface. The physical layer channel carrying the fourth information may be, for example, at least one of a PUCCH, a PUSCH, and an uplink reference channel.

[0106] Optionally, the resource configuration and / or carried content of the fourth information may be predefined by the protocol, or determined based on the resource configuration information and / or carried content of the fourth information indicated in the third information, or may be calculated by the relay device based on the third target parameter.

[0107] When the resource configuration and / or carried content of the fourth information is determined based on the resource configuration information and / or carried content of the fourth information indicated in the third information, the resource configuration information and / or carried content of the fourth information may be determined based on the resource configuration information and / or carried content of the fourth information included in the third information, or may be determined based on the resource configuration information and / or carried content of the fourth information indicated in the third information.

[0108] When the resource configuration and / or carried content of the fourth information is calculated based on the third target parameter, the third target parameter may be included in the third information or preset in the relay device. The third target parameter may be used to obtain at least one of the resource configuration and / or carried content of the first information, the resource configuration and / or carried content of the second information, and the resource configuration and / or carried content of the fourth information by calculation. Exemplarily, the third target parameter may be determined based on the identifier of the relay device and the mapping relationship between the identifier and the resource configuration information and / or carried content of the fourth information.

[0109] Optionally, the resource configuration of the fourth information may be based on network device scheduling. The method of the network device scheduling the resource configuration of the fourth information is the same as the method of the network device scheduling the resource configuration of the second information, which will not be repeated here.
