Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a communication method and device, and a computer-readable storage medium. Background Art

[0002] Ambient Internet of Things (A-IoT) refers to IoT devices that obtain energy from the environment and then use this energy for wireless communication, so it can also be understood as a passive IoT. Traditional A-IoT technologies include RFID (Radio Frequency Identification). The basic principle of RFID is to use backscattering to complete energy conversion and communication. RFID systems generally include readers and radio frequency electronic tags. The reader sends electromagnetic waves of a certain frequency outward through its antenna; when the electronic tag enters the working range of the transmitting antenna, an induced current is generated inside it and it is activated, so the information stored in it is sent out through the internal antenna; the sending process is to load modulate the received electromagnetic waves; the antenna of the reader receives the carrier signal from the electronic tag and transmits it to the reader.

[0003] Traditional RFID has some drawbacks (such as short transmission distance), and the limited reading range of several meters usually requires hand-held scanning, which leads to labor-intensive and time-consuming operations, or RFID entrances / doors lead to expensive deployment. In addition, the lack of interference management schemes leads to serious interference and capacity issues between RFID readers, especially in dense deployment. These drawbacks make it difficult for RFID to support large-scale networks with seamless coverage.

[0004] In order to solve the defects of traditional passive devices, passive IoT based on cellular networks has been proposed and is in the process of standardization. Currently, 4 topologies are considered in the cellular passive IoT solution (such as Figures 1 to 5 As shown), wherein the third topology structure 3 further includes two topologies 3-1 and 3-2.

[0005] For topology 3-1, the base station instructs the intermediate / auxiliary node to activate the A-IOT device (also known as a passive IoT terminal), and the activated A-IOT device sends data to the base station. However, the existing protocol standard does not specify the specific processing logic of the communicating parties, especially how the intermediate node should activate the A-IOT device, which may lead to the failure of A-IOT device activation and affect the communication reliability and communication effect.

[0038] Compared with the prior art, the technical solution of the embodiment of the present invention has the following beneficial effects:

[0039] On the intermediate node side, an embodiment of the present invention provides a communication method, including: receiving indication information, where the indication information is at least used to indicate device transmission information of one or more first devices; and sending a first instruction to at least one of the one or more first devices.

[0040] Compared with the prior art, which does not clearly define the specific processing logic of the communicating parties in the topological structure of the auxiliary node configuration in the environmental Internet of Things scenario, this embodiment ensures that the intermediate node can correctly activate the first device (for example, the environmental Internet of Things device) by carrying the indication information of the device transmission information, thereby improving the communication reliability. Furthermore, the indication information is at least used to indicate the device transmission information of one or more first devices, so that the base station can activate one or more environmental Internet of Things devices at one time through the intermediate node, thereby improving the communication efficiency and the communication effect.

[0041] Further, if the device type of the first device is the first type, the first instruction is sent, and a carrier signal is sent in a first manner in one or more working frequency domains of the first device according to the device transmission information; if the device type of the first device is the second type, the first instruction is sent.

[0042] Compared with the prior art, which has not considered the differences in activation methods for different device types, this embodiment indicates the device transmission information of the first device to the intermediate node, so that the intermediate node can learn the device type of the first device, and then determine the appropriate activation method according to the different device types to ensure the successful activation of the first device. Specifically, when performing the activation operation, the intermediate node determines whether it is necessary to send a radio frequency carrier for power supply according to the device type, thereby enabling the environmental Internet of Things device to send data while fully considering the device types of different environmental Internet of Things devices.

[0043] On the base station side, an embodiment of the present invention also provides a communication method, including: sending indication information, wherein the indication information is at least used to indicate device transmission information of one or more first devices; receiving data sent by at least one first device among the one or more first devices, wherein the first device is activated based on a first instruction, and the first instruction is received from an intermediate node.

[0061] As mentioned in the background technology, cellular passive IoT solutions currently consider four topologies: Topology 1, reference Figure 1 , the base station is directly connected to the A-IOT device, the A-IOT device sends data directly to the base station (also called A-IOT data, AmbientIoT data), and the base station sends signaling directly to the A-IOT device; topology 2, reference Figure 2 , the base station is connected to the A-IOT device through an intermediate node, where there is no direct connection between the base station and the A-IOT device; topology 3, reference Figure 3 and Figure 4 , the base station is connected to the A-IOT device through the intermediate node, and there is a connection between the base station and the A-IOT device; topology 4, reference Figure 5 , a terminal (eg, User Equipment (UE)) is directly connected to an A-IOT device. The connection method between the base station and the intermediate node may be, for example, a User to Network interface Universal (Uu).

[0062] The intermediate node in topology 2 has two-way transmission with the base station and the A-IOT device. In contrast, the intermediate node in topology 3 has one-way transmission with the base station and the A-IOT device, which helps to simplify the complexity and power consumption of the intermediate node. In this topology, the intermediate node can also be called an assisting node. In some embodiments, the intermediate node can be, for example, a repeater, a small base station, and a mobile terminal such as a mobile phone.

[0063] For topology 3, there are two types:

[0064] 1) Topology 3-1, reference Figure 3 , the base station instructs the intermediate node to activate the A-IOT device, the intermediate node activates the A-IOT device, and the A-IOT device sends data to the base station after being activated. The intermediate node in this topology is used to send activation information, configuration information, etc. After sending the aforementioned information to the A-IOT device, the intermediate node can feedback the information sending status to the base station.

[0065] 2) Topology 3-2, reference Figure 4, the base station triggers the A-IOT device to send data, the data sent by the A-IOT device is received by the intermediate node, and the intermediate node forwards the received data of the A-IOT device to the base station. The intermediate node in this topology is used for data forwarding and amplification.

[0066] For ambient IoT devices (hereinafter referred to as A-IOT devices), three types of devices (also known as passive IoT terminal types based on cellular networks) have been basically determined at this stage, namely Type A, Type B and Type C. Among them, Type A is similar to RFID and completes communication through backscattering. Type A does not have energy storage capabilities and does not have independent signal generation. Type B also completes communication based on backscattering. Similarly, Type B A-IOT devices do not have independent signal generation. Unlike Type A, Type B A-IOT devices have energy storage capabilities, and the stored energy can be used to amplify the reflected signal. Type C has energy storage capabilities and independent signal generation, that is, it has active RF components. In other words, Type A is a backscattering terminal without energy storage, Type B is a backscattering terminal with energy storage, and Type C is a terminal that actively sends signals with energy storage. Type C can be charged by RF energy.

[0067] In summary, A-IOT devices of types A, B and C may have different modulation and coding methods. For example, type A / B uses amplitude shift keying (ASK) or frequency shift keying (FSK), while type C uses other higher-order modulation and coding methods (such as orthogonal frequency division multiplexing (OFDM)).

[0068] After analysis, the inventors of the present application found that for topology structure 3-1, the prior art did not consider how the intermediate node should activate the A-IOT device, which resulted in the existing base station being very likely to fail to activate the A-IOT device through the intermediate node, or only being able to activate one A-IOT device at a time, affecting communication reliability and communication effects.

[0069] For example, for A-IOT devices of different device types, if the same activation method is used for all of them, if a power supply RF carrier is sent during activation, then resources will be wasted for type C A-IOT devices; if no power supply RF carrier is sent during activation, then type A and B A-IOT devices will not be successfully activated.

[0070] In addition, the prior art also does not consider how the intermediate node should forward the base station information to the A-IOT device, which may cause the information transfer to be lost / incomplete, and also affect the communication reliability and communication effect.

[0071] To solve at least one of the above technical problems, this embodiment provides a communication method, including: receiving indication information, wherein the indication information is at least used to instruct one or more first devices to transmit information; and sending a first instruction to at least one of the one or more first devices.

[0072] By adopting this implementation, the indication information carrying the device transmission information ensures that the intermediate node can correctly activate the first device (for example, A-IOT device), thereby improving the communication reliability. Furthermore, the indication information is at least used to indicate the device transmission information of one or more first devices, so that the base station can activate one or more A-IOT devices at one time through the intermediate node, thereby improving the communication efficiency and the communication effect.

[0073] The base station in the embodiment of the present application may generally refer to a network device, which is a device that provides wireless communication functions for a user terminal, and may also be referred to as an access network device, a radio access network (RAN) device, or an access network element, etc. Among them, the network device may support at least one wireless communication technology, such as LTE, NR, etc. For example, the network device includes, but is not limited to: a next generation base station (generation nodeB, gNB) in the fifth generation mobile communication system (5th-generation, 5G), an evolved node B (evolved node B, eNB), a radio network controller (radio network controller, RNC), a node B (node ​​B, NB), a base station controller (base station controller, BSC), a base transceiver station (base transceiver station, BTS), a home base station (for example, home evolved nodeB, or home node B, HNB), a baseband unit (baseband unit, BBU), a transmitting and receiving point (transmitting and receiving point, TRP), a transmitting point (transmitting point, TP), a mobile switching center, etc. The network device may also be a wireless controller, a centralized unit (CU), and / or a distributed unit (DU) in a cloud radio access network (CRAN) scenario, or the access network device may be a relay station, an access point, a vehicle-mounted device, a terminal device, a wearable device, and a network device in future mobile communications or a network device in a future evolved PLMN. In some embodiments, the network device may also be a device having a wireless communication function for a user terminal, such as a chip system. For example, the chip system may include a chip and may also include other discrete devices.

[0074] The terminal in the embodiment of the present application is a device with a wireless communication function, which can be called a user, a user terminal, a terminal device, a mobile station (MS), a mobile terminal (MT), an access terminal device, a vehicle-mounted terminal device, an industrial control terminal device, a user equipment (UE for short), a UE unit, a UE station, a mobile station, a remote station, a remote terminal device, a mobile device, a UE terminal device, a wireless communication device, a UE agent or a UE device, etc. The user terminal can be fixed or mobile. It should be noted that the user terminal can support at least one wireless communication technology, such as Long Term Evolution (LTE for short), new radio (NR), etc. For example, the user terminal may be a mobile phone, a tablet computer (pad), a desktop computer, a laptop computer, an all-in-one computer, a vehicle-mounted terminal, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in self driving, a wireless terminal in remote medical surgery, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a wearable device, a terminal device in a future mobile communication network, or a terminal device in a future evolved public mobile land network (PLMN), etc. In some embodiments of the present application, the user terminal may also be a device with a transceiver function, such as a chip system, wherein the chip system may include a chip and may also include other discrete devices.

[0075] The intermediate node in the embodiment of the present application may include any of the aforementioned network devices, and may also include any of the aforementioned terminals.

[0076] The A-IOT devices of the embodiments of the present application may include the aforementioned type A, type B, and type C A-IOT devices.

[0077] In order to make the above-mentioned objects, features and beneficial effects of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0078] Figure 6 It is a flow chart of a communication method according to the first embodiment of the present invention.

[0079] This implementation scheme can be applied to environmental IoT scenarios, specifically, it can be applied to adopting Figure 3 The topology structure of the auxiliary node configured as shown (hereinafter referred to as topology structure 3-1) is used for the application scenario of A-IOT communication.

[0080] In a specific implementation, the communication method provided in the following steps S601 to S602 may be executed by a chip with communication functions in the intermediate node, or may be executed by a baseband chip in the intermediate node.

[0081] Specifically, refer to Figure 6 The communication method described in this embodiment may include the following steps:

[0082] Step S601, receiving indication information, where the indication information is at least used to indicate device transmission information of one or more first devices;

[0083] Step S602: Send a first instruction to at least one of the one or more first devices.

[0084] More specifically, the first device may include an A-IOT device.

[0085] Further, the first instruction may be used to instruct the first device to send A-IOT data to the base station.

[0086] In some embodiments, in step S601, the intermediate node may receive indication information through a Uu port.

[0087] In a specific implementation, the device transmission information of the first device may include at least one of the following: frame structure, device type, device identification, encoding method, receiving frequency domain, working frequency domain, activation time, and data to be sent.

[0088] Specifically, the device transmission information may include device information of the first device, where the device information is used to describe information about the first device itself, such as a device identifier, a device type, and the like.

[0089] The device identification may be used to uniquely identify the first device.

[0090] The device type may include a first type and / or a second type, wherein the first type includes at least one of type A, type B in the first working mode, and type C in the second working mode, and the second type includes at least one of type B in the third working mode and type C in the fourth working mode. Specifically, the first and second working modes are low power modes; the third and fourth working modes are high power modes.

[0091] The first device can report its own energy status to the base station so that the base station can accurately know the device type of the first device. For example, the first device can actively report its current power status every time it sends data to the base station. If the reported value 0 indicates low power mode, the base station will instruct the intermediate node to supply power to the first device during the next interaction. The range of low power and high power can be defined by preset values ​​or by the terminal.

[0092] In response to receiving the indication information, the intermediate node can accurately obtain the device type of the first device, such as whether the first device is type A, type B, or type C, and can further obtain the power status of type B and type C first devices.

[0093] Furthermore, the device transmission information may include data transmission information of the first device, which is used to describe the transmission information when the first device receives / sends A-IOT data / signaling, for example, encoding mode, frame structure, receiving frequency domain, working frequency domain, etc.

[0094] The coding mode may be a modulation coding mode for receiving and sending data / signals by the first device, and may specifically include a first mode and / or a second mode, wherein the first mode may be, for example, an ASK mode, and the second mode may be, for example, an OFDM mode; or the first mode may be, for example, an OOK mode, and the second mode may be, for example, an ASK mode. Through the indicated coding mode, the intermediate node may determine the device type of the first device.

[0095] The frame structure may be a frame / timing structure of the first instruction. First devices of different device types correspond to different frame structures, and the intermediate node may determine the device type of the first device by indicating the frame structure.

[0096] For the first device of the first type, the device transmission information may indicate that an activation frame / timing structure A is sent at frequency X, and an activation frame / timing structure B is sent at frequency Y. Frequency X is used for power supply, and frequency Y is used for data transmission (including data to be sent and A-IOT data) and backscattering.

[0097] Alternatively, for the first device of the first type, different frame structures and waveforms may be sent at frequency point X in a time-division multiplexing (TDM) manner.

[0098] For the first device of the second type, the activation frame / timing structure B may be sent only at frequency Y.

[0099] The receiving frequency domain may be the frequency point at which the intermediate node sends the first instruction to the first device, corresponding to the downlink carrier of the first device. Further, the downlink carrier and the working carrier (corresponding to the uplink carrier of the first device) may be inconsistent in time domain and / or frequency domain.

[0100] The working frequency domain may be a frequency point at which the first device sends A-IOT data to the base station, corresponding to the uplink carrier of the first device. For the first type of first device, charging is performed first in the working frequency domain before sending data. A single first device may correspond to one or more working frequency domains.

[0101] For the first device of the first type, the intermediate node may send a radio frequency carrier to supply energy on carrier X. In some embodiments, a single subdivided device type (e.g., type A, type B in the first working mode, type C in the second working mode) may supply energy at multiple frequencies. In some embodiments, different subdivided device types may supply energy at different frequencies. This helps to avoid message collisions.

[0102] For the first device of the second type, the intermediate node may indicate that the operating frequency is carrier X.

[0103] Furthermore, the device transmission information may also include data that the base station needs to send to the first device through the intermediate node, that is, the data to be sent.

[0104] Furthermore, the device transmission information may also include activation information of the intermediate node activating the first device, such as the activation time. The activation time may include a first duration (denoted as delay1), and the intermediate node starts sending the first instruction after the first duration has passed since receiving the indication information to activate the first device. The unit of the first duration may be a time unit, and the time unit may be a communication granularity in the time domain between a terminal device (e.g., a first device, an intermediate node) and a network device (e.g., a base station). For example, the time unit may be a time slot, a mini-slot (i.e., a duration unit shorter than a time slot), a subframe, a symbol, a frame, an absolute time in seconds / microseconds / milliseconds, etc. In some embodiments, if the time unit of the first duration is a time slot, the value of the first duration may be zero.

[0105] In some embodiments, if the indication information is used to indicate device transmission information of multiple first devices, the parameters (e.g., frame structure, device type, device identification, encoding method, receiving frequency domain, working frequency domain, activation time and / or data to be sent) included in the device transmission information may correspond to the multiple first devices one by one. That is, each first device is indicated with a set of parameters accordingly.

[0106] Alternatively, at least a portion of the plurality of first devices may be indicated with the same set of parameters.

[0107] In a specific implementation, the indication information may be carried by dynamic control signaling. For example, at least a portion of the indication information may be carried by downlink control information (DCI). For another example, at least a portion of the indication information may be carried by a physical downlink shared channel (PDSCH).

[0108] In some embodiments, the starting time domain position for sending the first instruction to one or more first devices may be separated from the time unit where the DCI is located by a first time length.

[0109] Specifically, if the data for activating the first device (such as the device transmission information indicated by the indication information) are all carried in the DCI, the intermediate node starts sending the first instruction n time slots / symbols / microseconds after the time slot where the DCI is located, where n is the first time length.

[0110] In some embodiments, the time unit where the start time domain position of sending the first instruction to the one or more first devices and the end time domain position of the PDSCH are located may be separated by a first time length.

[0111] Specifically, if the data for activating the first device is included in the PDSCH, the intermediate node starts to send the first instruction n time slots / symbols / microseconds after the end time slot of the PDSCH, where n is the first time length.

[0112] For example, if the DCI indicates that part or all of the indication information is carried by PDSCH, it can be determined that data transmission is included, and the starting reference position of the first duration is the end position of PDSCH. If it is determined that data transmission is not included, the starting reference position of the first duration is the position where the DCI is received.

[0113] In a variation, the indication information may be carried by semi-static scheduling information. For example, all parameters in the device transmission information may be semi-statically configured, and the base station receives the A-IOT data sent by the first device every 10 ms.

[0114] In one variation, the indication information may be carried jointly by dynamic control signaling and semi-static scheduling information. For example, the transmission frequency may be semi-statically configured by RRC signaling, and combined with other parameters in the device transmission information indicated by the base station obtained through DCI, the intermediate node may correctly activate the first device.

[0115] In a specific implementation, step S602 may include the steps of: if the device type of the first device is the first type, sending a first instruction, and sending a carrier signal in a first manner in one or more working frequency domains of the first device according to the device transmission information; if the device type of the first device is the second type, sending the first instruction.

[0116] Specifically, for a first device of the first type, it is necessary to supply power to the first device and send a first instruction to the first device.

[0117] Furthermore, for the first device of the second type, since this type of terminal does not need to provide a backscatter source carrier, there is no need to send a carrier signal in the first manner in one or more working frequency domains of this type of terminal, but the first instruction can be directly sent.

[0118] In some embodiments, the first instruction and the carrier signal may be in different time periods in a fixed frame structure, or may be two independent signals.

[0119] In some embodiments, sending the carrier signal in the first manner may include maintaining a high level for a fixed period of time.

[0120] In a specific implementation, in step S602, the intermediate node may send the first instruction to all first devices indicated by the indication information respectively.

[0121] In a variation, in step S602, the intermediate node may send a first instruction to at least a portion of the multiple first devices indicated by the indication information, so as to selectively activate the first device.

[0122] For example, the intermediate node may select the first device to be activated or not activated according to the device type.

[0123] For another example, the intermediate node can select to activate or not activate the first device according to the device identifier. Taking the factory environment detection application scenario as an example, the intermediate node can pre-store the data collection type corresponding to each device identifier. Assuming that multiple first devices of the same device type in Factory E include two types of smoke alarms and temperature and humidity sensors, which collect smoke data and temperature and humidity data respectively, the intermediate node can distinguish whether it is the smoke alarm or the temperature and humidity sensor that needs to be activated this time by the device identifier.

[0124] Further, after step S602, the communication method of this embodiment may further include the step of reporting selection information, wherein the selection information is used to indicate the selection of at least one first device to send the first instruction. Thus, the base station can know which first devices will send data to be received by itself.

[0125] From the above, on the intermediate node side, this embodiment ensures that the intermediate node can correctly activate the first device (for example, A-IOT device) by carrying the indication information of the device transmission information, thereby improving the communication reliability. Furthermore, the indication information is at least used to indicate the device transmission information of one or more first devices, so that the base station can activate one or more A-IOT devices at one time through the intermediate node, thereby improving the communication efficiency and the communication effect.

[0126] Furthermore, by indicating the device transmission information of the first device to the intermediate node, the intermediate node can learn the device type of the first device, and then determine the appropriate activation method according to the different device types to ensure successful activation of the first device. Specifically, when performing the activation operation, the intermediate node determines whether it is necessary to send a radio frequency carrier for power supply according to the device type, thereby fully considering the device types of different A-IOT devices to enable the A-IOT device to send data.

Figure 6 The relevant description of the illustrated embodiment will not be repeated here.

[0138] In a specific implementation, if the device type of the first device is the first type, the intermediate node sends the first instruction and sends a carrier signal in a first manner in one or more working frequency domains of the first device according to the device transmission information; if the device type of the first device is the second type, the first instruction is sent.

[0141] In a specific implementation, the indication information is carried by dynamic control signaling or semi-static scheduling information, and / or the indication information is carried jointly by dynamic control signaling and semi-static scheduling information.

[0142] In a specific implementation, the indication information is carried in downlink control information, and the starting time domain position for sending the first instruction is separated from the time unit where the downlink control information is located by a first time length.

[0143] In a specific implementation, at least a portion of the indication information is carried in a physical downlink shared channel, and a time unit where a start time domain position of sending the first instruction is located and an end time domain position of the physical downlink shared channel are located is separated by a first time length.

[0144] In a specific implementation, after step S802, the communication method of this embodiment may further include the step of: receiving selection information, wherein the selection information is used to instruct the intermediate node to select the at least one first device to send the first instruction. Thus, the base station can obtain the first device that is actually activated among the one or more first devices indicated to the intermediate node.

[0145] In a specific implementation, the first device includes an A-IOT device.

[0146] From the above, on the base station side, this embodiment enables the base station to instruct the intermediate node to correctly activate the first device (for example, A-IOT device) through the indication information carrying the device transmission information, thereby improving the communication reliability. Furthermore, the indication information is at least used to indicate the device transmission information of one or more first devices, so that the base station can activate one or more A-IOT devices at one time through the intermediate node, thereby improving the communication efficiency and the communication effect.

[0147] Furthermore, the base station using this implementation indicates the device type of each first device by sending indication information to the intermediate node, ensuring that the intermediate node can accurately know the device type of the A-IOT device to be activated, and then determine the appropriate activation method according to different device types. In this way, communication efficiency can be improved and communication effects can be improved.

[0148] Furthermore, the indication information includes device types of multiple first devices, and the multiple device types are at least partially different. Therefore, by adopting this embodiment, the base station can activate A-IOT devices of multiple device types at one time through the intermediate node.

[0149] Fig. 9 FIG. 9 is a schematic diagram of the structure of a communication device 9 according to a fourth embodiment of the present invention. A person skilled in the art will appreciate that the communication device 9 described in this embodiment can be used to implement the above Figure 8 The method and technical solution described in the embodiments.

[0150] Specifically, refer to Fig. 9The communication device 9 described in this embodiment may include: a sending module 91, used to send indication information, wherein the indication information is at least used to indicate device transmission information of one or more first devices; a receiving module 92, used to receive data sent by at least one first device among the one or more first devices, wherein the first device is activated based on a first instruction, and the first instruction is received from an intermediate node.

[0151] For more information about the working principle and working mode of the communication device 9, please refer to the above Figure 8 The relevant description in will not be repeated here.

[0153] Fig.10 It is a flow chart of a communication method according to the fifth embodiment of the present invention.

[0154] This implementation scheme can be applied to A-IOT scenarios, and can be applied to the following scenarios: Figure 3 The topology structure 3-1 shown is an application scenario for A-IOT communication.

[0155] In a specific implementation, the communication method provided in the following steps S1001 to S1002 may be executed by a chip with a communication function in the first device, or may be executed by a baseband chip in the first device. The first device may be, for example, an A-IOT device.

[0156] Specifically, refer to Fig.10 The communication method described in this embodiment may include the following steps:

[0157] Step S1001: receiving a first instruction sent by an intermediate node, where the first instruction is sent in response to indication information sent by a base station, where the indication information is at least used to instruct device transmission information of one or more first devices;

[0158] Step S1002: Send data to the base station.

[0159] Those skilled in the art will appreciate that step S1001 can be regarded as the same as the above Figure 6 The execution steps corresponding to step S602 in the embodiment shown in the figure are complementary to each other in terms of specific implementation principles and logic. Figure 8The execution steps corresponding to step S802 in the embodiment shown in the figure are complementary to each other in terms of specific implementation principles and logic. Figure 6 and Figure 8 The relevant description of the illustrated embodiment will not be repeated here.

[0160] In a specific implementation, the receiving of the first instruction sent by the intermediate node includes: if the device type of the first device is the first type, receiving the first instruction sent by the intermediate node, and receiving a carrier signal in a first manner in one or more working frequency domains of the first device; if the device type of the first device is the second type, receiving the first instruction sent by the intermediate node.

[0161] Specifically, for the first device of the first type, it is necessary to receive a carrier signal in a first manner in one or more working frequency domains for charging. For the first device of the second type, since it has energy storage capability and is currently in a high power mode, it does not need to receive a carrier signal in the working frequency domain, but can obtain energy from its own preset energy storage module.

[0162] In a specific implementation, the first type includes at least one of type A, type B in the first working mode, and type C in the second working mode; and / or the second type includes at least one of type B in the third working mode and type C in the fourth working mode.

[0163] In a specific implementation, the device transmission information of the first device includes at least one of the following: frame structure, device type, device identification, encoding method, receiving frequency domain, working frequency domain, activation time, and data to be sent.

[0164] In a specific implementation, the indication information is carried by dynamic control signaling or semi-static scheduling information, and / or the indication information is carried jointly by dynamic control signaling and semi-static scheduling information.

[0165] In a specific implementation, the indication information is carried in downlink control information, and the start time domain position for receiving the first instruction is separated from the time unit where the downlink control information is located by a first time length.

[0166] In a specific implementation, at least a portion of the indication information is carried in a physical downlink shared channel, and a time unit where a start time domain position of receiving the first instruction and an end time domain position of the physical downlink shared channel are located is separated by a first time length.

[0167] From the above, on the first device side, this implementation ensures that the first device can be correctly activated by the intermediate node to successfully send data to the base station by carrying indication information carrying device transmission information, thereby improving communication reliability.

[0168] Furthermore, the first device using this embodiment can determine a suitable energy supply path according to its own device type, such as obtaining energy from an intermediate node or a preset energy storage module to be successfully activated, and send data to the base station with reliable energy supply support.

[0169] Fig.11 FIG. 1 is a schematic diagram of the structure of a communication device 11 according to the sixth embodiment of the present invention. A person skilled in the art will appreciate that the communication device 11 described in this embodiment can be used to implement the above Fig.10 The method and technical solution described in the embodiments.

[0170] Specifically, refer to Fig.11 The communication device 11 described in this embodiment may include: a receiving module 111, used to receive a first instruction sent by an intermediate node, the first instruction is sent in response to an indication information sent by a base station, and the indication information is at least used to indicate device transmission information of one or more first devices; a sending module 112, used to send data to the base station.

[0171] For more information about the working principle and working mode of the communication device 11, please refer to the above Fig.10 The relevant description in will not be repeated here.

[0172] In a specific implementation, the above-mentioned communication device 11 may correspond to a chip with a communication function in the first device, or to a chip with a data processing function, such as a system-on-a-chip (SOC), a baseband chip, etc.; or to a chip module in the first device that includes a chip with a communication function; or to a chip module with a chip with a data processing function, or to the first device.

[0173] In a specific implementation, each module / unit included in each device or product described in the above embodiments may be a software module / unit or a hardware module / unit, or may be partly a software module / unit and partly a hardware module / unit.

[0174] For example, for each device or product applied to or integrated in a chip, each module / unit contained therein may be implemented in the form of hardware such as circuits, or at least some of the modules / units may be implemented in the form of software programs, which run on a processor integrated inside the chip, and the remaining (if any) modules / units may be implemented in the form of hardware such as circuits; for each device or product applied to or integrated in a chip module, each module / unit contained therein may be implemented in the form of hardware such as circuits, and different modules / units may be located in the same component (such as a chip, circuit module, etc.) or different components of the chip module, or at least some of the modules / units may be implemented in the form of software programs. The element can be implemented in the form of a software program, which runs on a processor integrated inside the chip module, and the remaining (if any) modules / units can be implemented in the form of hardware such as circuits; for various devices and products applied to or integrated in the terminal, the various modules / units contained therein can be implemented in the form of hardware such as circuits, and different modules / units can be located in the same component (for example, chip, circuit module, etc.) or in different components in the terminal, or, at least some modules / units can be implemented in the form of a software program, which runs on a processor integrated inside the terminal, and the remaining (if any) modules / units can be implemented in the form of hardware such as circuits.

[0175] In a typical application scenario, refer to Fig.12 , the base station sends the indication information to the intermediate node at time t1. The intermediate node starts sending the first instruction to the A-IOT device at time t2 according to the activation time indicated by the indication information.

[0176] Specifically, the activation time may be indicated by a first duration. The first duration may be determined according to a decoding time of the intermediate node decoding indication information.

[0177] For example, if at least part of the indication information is included in PDSCH, the starting reference position of the first duration is the end position of PDSCH. For another example, if all the indication information is included in DCI, the starting reference position of the first duration is the time slot where DCI is located.

[0178] Further, from time t2 to t4, the intermediate node activates the A-IOT device and sends data to the A-IoT device.

[0179] For the intermediate node side, according to the device type of the A-IOT device, the intermediate node sends data to the A-IOT device at time t2 to t4. The sent data may include the data to be sent indicated by the indication information, and may also include the content that the intermediate node requires the A-IOT device to execute.

[0180] If the indication information indicates that the A-IOT device is of the first type and indicates that its operating frequency domain is X, the intermediate node sends a radio frequency carrier signal at the X frequency point and sends a first instruction in the receiving frequency domain indicated by the indication information.

[0181] If the indication information indicates that the A-IOT device is of the second type and indicates that its operating frequency is X, the intermediate node sends the first instruction at the receiving frequency indicated by the indication information. In this example, the intermediate node does not need to send the radio frequency carrier at the X frequency.

[0182] The RF carrier signal is used to enable the transmission of A-IoT. If it is the first type, it needs an external RF carrier to enable backscattering to send data. For the second type, it has its own transmission capability, so there is no need for external backscattering to enable data transmission.

[0183] For the A-IOT device side, according to the type of the device itself, the A-IOT device receives a carrier signal in a first manner at the working frequency point from t2 to t4 for charging, and / or receives and decodes a first instruction.

[0184] Furthermore, after time t4, the intermediate node successfully enables the A-IOT device, and the activated A-IOT device sends data to the base station from time t4 to t5. Accordingly, time t4 to t5 can be recorded as the sending window of the A-IOT device. The base station receives the data sent by the A-IOT device within the sending window.

[0185] In a typical application scenario, it is assumed that the indication information indicates the device transmission information of an A-IOT device, or the indication information indicates the device transmission of multiple A-IOT devices and the intermediate node selectively activates one of the A-IOT devices. Fig.12 and Fig.13 The intermediate node receives DCI on the downlink carrier of the Uu port in time slot n (corresponding to time t1), and the indication information carried in the DCI instructs the intermediate node to send data in the downlink carrier of the A-IoT device in time slot m (in the time period from t2 to t3) in the indicated coding manner.

[0186] If the device type of the indicated A-IoT device is the first type, and / or the encoding method is the first method (for example, the A-IOT device is in low power mode of type A or B, and the encoding method is ASK), the intermediate node starts sending an unmodulated or specially modulated RF carrier on the uplink carrier X in time slot z (in the time period from t2 to t3) to provide a backscattered source carrier for the A-IoT device).

[0187] If the device type of the indicated A-IoT device is the second type, and / or the encoding method is the second method (for example, the A-IOT device is type C and the encoding method is OFDM), the intermediate node does not need to send an unmodulated or specially modulated RF carrier on the uplink carrier X starting at time slot z, because such A-IOT devices do not need to provide a backscatter source carrier.

[0188] It should be noted that the time slot z and the time slot m may be located in the same time unit or in different time units.

[0189] In a typical application scenario, it is assumed that the indication information indicates device transmission information of multiple A-IOT devices, or the indication information indicates device transmission of multiple A-IOT devices and the intermediate node selectively activates at least two of the A-IOT devices. Fig.12 and Fig.14 , the intermediate node receives DCI on the downlink carrier of the Uu port in time slot n, and the DCI indicates that part or all of the indication information is carried by PDSCH, then the intermediate node receives the indication information carried by PDSCH in time slot m (corresponding to time t1). After a delay of the first duration after the end position of PDSCH, data is sent in coding mode 1 on downlink carrier 1 of the A-IoT device in time slot z, and data is sent in coding mode 2 on downlink carrier 2 of the A-IoT device in time slot z.

[0190] If the device type of the indicated A-IoT device includes the first type and / or the encoding method is the first method (for example, the A-IOT device is type A, type B or C in low power mode, and the encoding method is ASK), the intermediate node starts sending an unmodulated or specially modulated RF carrier on the uplink carrier X in time slot y' (in the time period from t2 to t3) to provide a backscattered source carrier for the first type of A-IOT device among the indicated multiple A-IoT devices.

[0191] If the device type of all indicated A-IoT devices is the second type and / or the encoding method is the second method (for example, the A-IOT device is type B or C in high power mode, and the encoding method is OFDM), then the intermediate node does not need to send an unmodulated or specially modulated RF carrier on the uplink carrier X starting at time slot y', because such A-IOT devices do not need to provide a backscatter source carrier).

[0192] In this application scenario, the first duration may be smaller than the delay of message 3 (Msg3).

[0193] It should be noted that the time slot z and the time slot y' may be located in the same time unit or in different time units.

[0194] In some embodiments, type A and type B in low power mode may correspond to different uplink carriers X. Accordingly, the intermediate node starts sending carrier signals in the first mode corresponding to the A-IOT device of each subdivided device type at the uplink carrier X corresponding to each subdivided device type at time slot y'.

[0195] In some embodiments, the timing, frequency, encoding method, etc. of sending the first instruction by the intermediate node to the first devices of different device types can be determined by the base station using the same or different configurations and indicated through indication information.

[0196] The embodiment of the present invention further provides a computer-readable storage medium, which is a non-volatile storage medium or a non-transitory storage medium, on which a computer program is stored, and when the computer program is executed by a processor, the steps of the communication method provided in any of the above embodiments are executed. Preferably, the storage medium may include a computer-readable storage medium such as a non-volatile memory or a non-transitory memory. The storage medium may include a ROM, a RAM, a magnetic disk or an optical disk, etc.
