[0049] Before introducing the technical solutions of the present application, the related technologies involved in the present application are introduced and explained. The following related technologies can be combined with the technical solutions of the embodiments of the present application in any way, and all belong to the protection scope of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.
[0050] 1. Zero-power communication technology principle
[0051] In recent years, the application of zero-power devices is more and more widely. The zero-power Internet of Things can also be called Ambient power enabled IoT, Ambient IoT for short, and is also called passive IoT in some technical literature. Ambient IoT device means an IoT device that uses various environmental energies (such as wireless radio frequency energy, light energy, solar energy, thermal energy, mechanical energy, and various environmental energies) to drive itself. Such a device can have no energy storage capability, or can have very limited energy storage capability (such as using a capacitor with a capacity of several tens of uF). Compared with existing IoT devices, Ambient IoT devices have many advantages such as no conventional battery, maintenance-free, small size, low complexity, low cost, long service life, and the like.
[0052] Zero-power communication adopts energy harvesting and backscattering communication technology. A zero-power communication network is composed of network devices and zero-power devices, as shown in FIG. 2. The network device is used to send wireless power supply signals, downlink communication signals to the zero-power device, and receive backscattering signals of the zero-power device. A basic zero-power device includes an energy harvesting module, a backscattering communication module, and a low-power computing module. In addition, the zero-power device can also have a memory or a sensor for storing some basic information (such as article identification) or obtaining environmental temperature, environmental humidity, and other sensor data.
[0053] The key technologies of zero-power communication mainly include radio frequency energy harvesting and backscattering communication.
[0054] 1.1. Radio frequency energy harvesting (RF Power Harvesting)
[0055] As shown in FIG. 3, the radio frequency energy harvesting module is based on the principle of electromagnetic induction to realize the collection of space electromagnetic wave energy, and then obtain the energy required to drive the zero-power device to work, for example, to drive the low-power demodulation and modulation module, sensor, and memory reading, and the like. Therefore, the zero-power device does not need a traditional battery.
[0056] 1.2. Backscattering communication (Back Scattering)
[0057] As shown in FIG. 4, the zero-power communication terminal receives the wireless signal transmitted by the network, modulates the wireless signal, loads the information to be transmitted, and radiates the modulated signal from the antenna. This information transmission process is called backscatter communication. Backscatter and load modulation are inseparable. Load modulation adjusts and controls the circuit parameters of the oscillation loop of the zero-power device according to the beat of the data stream, so that the size of the impedance of the electronic tag changes, thereby completing the modulation process. Load modulation technology mainly includes resistance load modulation and capacitance load modulation. In resistance load modulation, a resistance is connected in parallel with the load, and the resistance is turned on or off based on the control of the binary data stream, as shown in FIG. 5. The on-off of the resistance will cause the change of the circuit voltage, so as to realize amplitude shift keying (ASK) modulation, that is, the modulation and transmission of the signal are realized by adjusting the amplitude of the backscatter signal of the zero-power device. Similarly, in capacitance load modulation, the on-off of the capacitance can realize the change of the circuit resonance frequency, and realize frequency shift keying (FSK) modulation, that is, the modulation and transmission of the signal are realized by adjusting the working frequency of the backscatter signal of the zero-power device.
[0058] As can be seen, the zero-power device modulates the incoming signal by means of load modulation to realize the backscatter communication process. Therefore, the zero-power device has the following advantages:
[0059] (1) The terminal does not actively transmit signals, so it does not need complex radio frequency links such as PA (Power Amplifier), radio frequency filters, etc.
[0060] (2) The terminal does not need to actively generate high-frequency signals, so it does not need a high-frequency crystal oscillator;
[0061] (3) With backscatter communication, the terminal signal transmission does not consume the terminal's own energy.
[0062] 1.3. Application scenarios of zero-power communication
[0063] Due to the significant advantages of zero cost, zero power consumption, small size, etc., zero-power communication can be widely used in various industries, such as logistics, intelligent warehousing, smart agriculture, energy and power, industrial internet, etc. for vertical industries; it can also be applied to personal applications such as smart wearable, smart home, etc.
[0064] 1.4. Classification of zero-power devices
[0065] Based on the energy source and usage of the zero-power device, the zero-power device can be classified as follows:
[0066] (1) Passive zero-power device
[0067] The zero-power device does not need to be internally provided with a battery. When the zero-power device approaches a network device (such as a reader of an RFID (Radio Frequency Identification) system), the zero-power device is in the near field formed by the antenna radiation of the network device. Therefore, the antenna of the zero-power device generates an induced current through electromagnetic induction, and the induced current drives the low-power chip circuit of the zero-power device. The zero-power device realizes demodulation of a forward link signal (downlink, a link from the network device to the zero-power device) and signal modulation of a backward link (uplink, a link from the zero-power device to the network device). For a backscatter link, the zero-power device uses a backscatter implementation to transmit signals.
[0068] As can be seen, the passive zero-power device does not need to be internally provided with a battery to drive, and is a truly zero-power device.
[0069] The passive zero-power device does not need a battery, and the radio frequency circuit and the baseband circuit are very simple, for example, do not need LNA (Low Noise Amplifier), PA, crystal oscillator, ADC (Analog-to-Digital Converter), and other devices, and therefore has many advantages such as small size, light weight, very low price, and long service life.
[0070] (2) Semi-passive zero-power device
[0071] The semi-passive zero-power device itself does not install a conventional battery, but can use an RF (Radio Frequency) energy harvesting module to harvest radio wave energy, or use a solar energy, light energy, thermal energy, kinetic energy harvesting module to harvest energy, and store the harvested energy in an energy storage unit (such as a capacitor). After the energy storage unit obtains energy, it can drive the low-power chip circuit of the zero-power device. The zero-power device realizes demodulation of a forward link signal and signal modulation of a backward link. For a backscatter link, the zero-power device uses a backscatter implementation to transmit signals.
[0072] As can be seen, the semi-passive zero-power device does not need to be internally provided with a battery to drive, and although energy stored in the capacitor is used in work, the energy is derived from radio energy harvested by the energy harvesting module, and therefore is also a truly zero-power device.
[0073] The semi-passive zero-power device inherits many advantages of the passive zero-power device, and therefore has many advantages such as small size, light weight, very low price, and long service life.
[0074] (3) Active zero-power device
[0075] Some zero-power devices used in some scenarios can also be active zero-power devices, which can be built-in with a battery (a conventional battery, such as a dry battery, a rechargeable lithium battery, etc.). The battery is used to drive the low-power chip circuit of the zero-power device. The battery is used to drive the low-power chip circuit of the zero-power device. The work of demodulating the forward link signal and modulating the backward link signal is realized. However, for the backscatter link, the zero-power device uses the backscatter implementation mode to transmit signals. Therefore, the zero-power of this type of terminal mainly reflects that the signal transmission of the reverse link does not require the power of the terminal itself, but uses the backscatter mode. Although the active zero-power device uses a battery, due to the use of ultra-low power communication technology, the power consumption is very low, so the working life of the battery can be greatly improved compared with the prior art.
[0076] The active zero-power device is built-in with a battery to supply power to the RFID chip to increase the read-write distance of the tag and improve the reliability of communication. Therefore, it can be applied in some scenarios with relatively high requirements on communication distance, reading delay, etc.
[0077] Classification of zero-power devices based on transmitter types.
[0078] As known, the service type of the zero-power Internet of Things will also be mainly based on the industry service. Therefore, according to the way in which the zero-power terminal transmits data, the following types can be divided:
[0079] (1) Zero-power device based on backscatter
[0080] This type of zero-power device uses the backscatter mode to transmit uplink data as described above. This type of device does not have an active transmitter for active transmission, but only has a backscatter transmitter. Therefore, when the terminal transmits data, the network device needs to provide a carrier, and the terminal device performs backscatter based on the carrier to realize data transmission.
[0081] (2) Zero-power device based on active transmitter
[0082] This type of zero-power device uses an active transmitter with active transmission capability to transmit uplink data, so that the active transmitter of the zero-power device can transmit data without the need for the network device to provide a carrier when transmitting data. The active transmitter suitable for the zero-power device can be, for example, an ultra-low-power ASK transmitter, an ultra-low-power FSK transmitter, etc. Based on the current implementation, the overall power consumption of this type of transmitter can be reduced to 400-600 uw when transmitting a 100 uw signal.
[0083] (3) Zero-power device with both backscatter and active transmitter
[0084] Such terminals can support both backscattering and active transmitters. The terminals can determine which type of uplink signal transmission to use, backscattering or active transmitter, based on different situations (e.g., the situation of power, available environmental energy), or based on the scheduling of network equipment.
[0085] 2. Cellular passive IoT
[0086] Cellular IoT is booming, and 3GPP (3rd Generation Partnership Project) has standardized NB-IoT (Narrow Band Internet of Things), MTC (Machine Type Communication), RedCap (Reduced Capability), and other IoT technologies, but there are still many IoT communication needs in scenarios that cannot be met using existing technologies, for example:
[0087] (1) Strict communication environment
[0088] Some IoT scenarios may face extreme environments such as high temperature, extremely low temperature, high humidity, high pressure, high radiation, or high-speed motion. For example, ultra-high voltage substations, high-speed train track monitoring, high-cold environment monitoring, industrial production lines, etc. In these scenarios, due to the working environment limitations of conventional power supplies, existing IoT terminals will not be able to work. In addition, extreme working environments are also not conducive to the maintenance of IoT, such as replacing batteries.
[0089] (2) Extremely small terminal form factor requirements
[0090] Some IoT communication scenarios, such as food traceability, commodity circulation, and smart wearables, require terminals to have extremely small sizes to facilitate their use in these scenarios. For example, IoT terminals for commodity management in the circulation link are usually in the form of electronic tags, embedded in commodity packaging in a very small form. For another example, lightweight wearable devices can meet user needs while improving user experience.
[0091] (3) Extremely low-cost IoT communication needs
[0092] Many IoT communication scenarios require the cost of IoT terminals to be low enough to enhance the competitiveness relative to other alternative technologies. For example, in logistics or warehouse scenarios, in order to facilitate the management of a large number of circulating goods, an IoT terminal can be attached to each good, so as to complete the precise management of the entire logistics process and cycle through the communication between the terminal and the logistics network. These scenarios require the price of the IoT terminal to be competitive enough.
[0093] Therefore, in order to cover these unmet IoT communication needs, there is a need to develop ultra-low-cost, extremely small, battery-free or maintenance-free IoT in cellular networks, and zero-power IoT can exactly meet this demand.
[0094] Based on the discussion of Ambient IoT application scenarios by 3GPP, Ambient IoT can be used in at least the following four scenarios:
[0095] (1) object identification, such as logistics, production line product management, and supply chain management;
[0096] (2) environmental monitoring, such as temperature, humidity, and harmful gas monitoring of working and natural environments;
[0097] (3) positioning, such as indoor positioning, intelligent search for objects, and production line object positioning;
[0098] (4) intelligent control, such as intelligent control of various appliances in smart homes (turning on / off air conditioners, adjusting temperature), and intelligent control of various facilities in agricultural greenhouses (automatic irrigation, fertilization).
[0099] 3GPP discussed and passed the research project of A-IoT, which contains at least the following two types of A-IoT devices:
[0100] The first type of A-IoT device: ~1 uW peak power consumption, which has energy storage, an initial sampling frequency offset of 10X ppm, no uplink and downlink power amplifier, and transmits uplink transmission by backscattering an external carrier. Exemplarily, the range of X is 4 to 5, i.e., [4, 5].
[0101] The second type of A-IoT device: peak power consumption less than a few hundred uW, which has energy storage, an initial sampling frequency offset of 10X ppm, and can be configured with uplink and / or downlink power amplifiers, and can transmit uplink transmission by actively emitting an uplink generated inside the A-IoT device or by backscattering an external carrier. Exemplarily, the range of X is 4 to 5, i.e., [4, 5].
[0102] A-IoT mainly considers the following two deployment scenarios / topologies, which correspond to the diagram shown in FIG. 6:
[0103] (1) D1T1 (Deployment scenario 1 with Topology 1): BS Ambient IoT device, the base station and the A-IoT device directly perform bidirectional signaling and / or data communication. Among them, the base station sending to the A-IoT device and the base station receiving the A-IoT device can be two different base stations.
[0104] (2) D2T2 (Deployment scenario 2 with Topology 2): BS intermediate node Ambient IoT device, the A-IoT device and the intermediate node perform bidirectional communication, and the intermediate node can relay signaling and / or data between the BS and the A-IoT device. In the SID discussion stage, the intermediate node is finally determined as a UE (User Equipment) under network control, and the intermediate node is located indoors.
[0105] Currently, two types of services are mainly considered in the A-IoT research project, one is DT (Device-terminated) and the other is DO-DTT (Device-originated-device-terminated triggered). DT mainly refers to executing a specific action by A-IoT terminal through downlink command, for example, in the smart home scenario, the A-IoT device is instructed to "turn on the air conditioner", and the A-IoT device performs the corresponding operation. DO-DTT mainly refers to triggering the A-IoT device to report information through downlink command, typical scenarios are warehouse inventory or sensor sensing, for example, triggering a number of zero-power tags to report ID or sensor data through triggering information.
[0106] The deployment scenario 1 in FIG. 6 can be further refined into sub-figures 1-1 to 1-4 in FIG. 7. Specifically, in sub-figure 1-1, Reader to Device (R2D) transmission is from Reader 1 to Device, and Device to Reader (D2R) transmission is from Device to Reader 2, i.e., the sender of R2D transmission and the receiver of D2R transmission are not the same Reader. When Device performs D2R transmission, Reader 1 provides the carrier wave (CW) for backscattering for Device to complete the D2R transmission. In sub-figure 1-2, R2D transmission is from Reader to Device, and D2R transmission is from Device to Reader, i.e., the sender of R2D transmission and the receiver of D2R transmission are the same Reader. When Device performs D2R transmission, the Reader can provide the carrier wave for backscattering for Device to complete the D2R transmission. In sub-figure 1-3, R2D transmission is from Reader to Device, and D2R transmission is from Device to Reader, i.e., the sender of R2D transmission and the receiver of D2R transmission are the same Reader. Unlike sub-figure 1-2, when Device performs D2R transmission, a dedicated carrier wave node (CWN) provides the carrier wave for backscattering for Device to complete the D2R transmission. In sub-figure 1-4, R2D transmission is from Reader to Device, and D2R transmission is from Device to Reader, i.e., the sender of R2D transmission and the receiver of D2R transmission are the same Reader. In this scenario, since Device uses active transmission rather than backscattering, there is no need to provide the carrier wave. It can be understood that in sub-figures 1-1 to 1-4, the Reader is a base station.
[0107] Similarly, the deployment scenario 2 in FIG. 6 can be further refined into sub-figures 2-1 to 2-4 in FIG. 7. Specifically, in sub-figure 2-1, R2D transmission is from Reader 1 to Device, and D2R transmission is from Device to Reader 2, i.e., the sending end of R2D transmission and the receiving end of D2R transmission are not the same Reader. When Device performs D2R transmission, Reader 1 provides the carrier for backscattering for Device to complete D2R transmission. In addition, Reader 1 and Reader 2 are controlled by the network, i.e., Reader 1 and Reader 2 perform uplink and downlink transmission with the base station. In sub-figure 2-2, R2D transmission is from Reader to Device, and D2R transmission is from Device to Reader, i.e., the sending end of R2D transmission and the receiving end of D2R transmission are the same Reader. When Device performs D2R transmission, the Reader can provide the carrier for backscattering for Device to complete D2R transmission. In addition, the Reader is controlled by the network, i.e., the Reader performs uplink and downlink transmission with the base station. In sub-figure 2-3, R2D transmission is from Reader to Device, and D2R transmission is from Device to Reader, i.e., the sending end of R2D transmission and the receiving end of D2R transmission are the same Reader. Different from sub-figure 2-2, when Device performs D2R transmission, a dedicated CWN provides the carrier for backscattering for Device to complete D2R transmission. In addition, the Reader is controlled by the network, i.e., the Reader performs uplink and downlink transmission with the base station, and the CWN is controlled by the BS (Base Station) or the Reader, i.e., the CWN performs signaling interaction with the base station or the Reader. In sub-figure 2-4, R2D transmission is from Reader to Device, and D2R transmission is from Device to Reader, i.e., the sending end of R2D transmission and the receiving end of D2R transmission are the same Reader. In this scenario, since Device adopts active transmission instead of backscattering, there is no need to provide the carrier. It can be understood that in sub-figures 2-1 to 2-4, the Reader is an intermediate node.
[0108] 3. Coexistence of A-IoT system and NR system
[0109] For the A-IoT system, coexistence with the existing NR system also needs to be considered during deployment. Specifically, the following three cases can be divided:
[0110] Case 1: In the above D1T1 scenario, R2D can employ DL (Downlink) spectrum, and D2R can employ UL (Uplink) spectrum.
[0111] Case 2: In the above D1T1 scenario, R2D can employ DL spectrum, and D2R can employ DL spectrum.
[0112] Case 3: In the above D2T2 scenario, R2D can employ UL spectrum, and D2R can employ UL spectrum.
[0113] For Case 1, the interference analysis is shown in FIG. 8. In FIG. 8, the sub-figures 1-1 to 1-4 in FIG. 7 are further divided into A and B cases. In A, the interference between R2D transmission and NR Uu transmission is analyzed, and in B, the interference between D2R transmission and NR Uu transmission is analyzed. Specifically, as shown in sub-figures 1-1-A to 1-4-A in FIG. 8, since R2D transmission employs DL spectrum, there is interference between R2D transmission and NR DL transmission. That is, the downlink transmission from the BS to the NR UE can cause interference to the reception of R2D, and meanwhile, the R2D transmission can also cause interference to the reception of NR DL. As shown in sub-figures 1-1-B to 1-4-B in FIG. 8, since D2R transmission employs UL spectrum, there is interference between D2R transmission and NR UL transmission. That is, the uplink transmission from the NR UE to the BS can cause interference to the reception of D2R, and meanwhile, the D2R transmission can also cause interference to the reception of NR UL.
[0114] For Case 2, the interference analysis is shown in FIG. 9. In FIG. 9, the sub-figures 1-1 to 1-4 in FIG. 7 are further divided into A and B cases. In A, the interference between R2D transmission and NR Uu transmission is analyzed, and in B, the interference between D2R transmission and NR Uu transmission is analyzed. Specifically, as shown in sub-figures 1-1-A to 1-4-A in FIG. 9, since R2D transmission employs DL spectrum, there is interference between R2D transmission and NR DL transmission. That is, the downlink transmission from the BS to the NR UE can cause interference to the reception of R2D, and meanwhile, the R2D transmission can also cause interference to the reception of NR DL. As shown in sub-figures 1-1-B to 1-4-B in FIG. 9, since D2R transmission employs DL spectrum, there is interference between D2R transmission and NR DL transmission. That is, the downlink transmission from the BS to the NR UE can cause interference to the reception of D2R, and meanwhile, the D2R transmission can also cause interference to the reception of NR DL.
[0115] For Case 3, the interference analysis is shown in FIG. 10. In FIG. 10, the sub-figures 2-1 to 2-4 in FIG. 7 are further divided into A and B cases. In A, the interference between R2D transmission and NR Uu transmission is analyzed, and in B, the interference between D2R transmission and NR Uu transmission is analyzed. Specifically, as shown in sub-figures 2-1-A to 2-4-A in FIG. 10, there is interference between R2D transmission and NR UL transmission due to the UL spectrum adopted by R2D transmission. That is, the uplink transmission from NR UE to BS can cause interference to the reception of R2D, and the R2D transmission can also cause interference to the reception of NR UL. As shown in sub-figures 2-1-B to 2-4-B in FIG. 10, there is interference between D2R transmission and NR UL transmission due to the UL spectrum adopted by D2R transmission. That is, the uplink transmission from NR UE to BS can cause interference to the reception of D2R, and the D2R transmission can also cause interference to the reception of NR UL.
[0116] 4. Frame structure of R2D and D2R transmission
[0117] R2D transmission, i.e., Reader-to-Device transmission, also referred to as A-IoT downlink transmission, can correspond to the base station-to-A-IoT device transmission in the deployment scenario 1 in FIG. 7, or the intermediate node-to-A-IoT device transmission in the deployment scenario 2 in FIG. 7. D2R transmission, i.e., Device-to-Reader transmission, also referred to as A-IoT uplink transmission, can correspond to the A-IoT device-to-base station transmission in the deployment scenario 1 in FIG. 7, or the A-IoT device-to-intermediate node transmission in the deployment scenario 2 in FIG. 7.
[0118] The current standard designs the frame structure of R2D transmission and D2R transmission as shown in subgraph 1 and subgraph 2 of FIG. 11 respectively. The common point of the above two structures is that a preamble is designed before PRDCH (Physical Reader to Device Channel) and PDRCH (Physical Device to Reader Channel). The preamble can be used for timing calibration, can be used for indicating the starting position of transmission, and can also be used for indicating simple control information. The PRDCH can be used to carry data from the Reader to the Device, or can be used to carry control information from the Reader to the Device, for example, including physical layer control information (such as ACI (A-IoT Control Information)) and / or high layer control information (such as MAC-CE (Medium Access Control Control Element)). Similarly, the PDRCH can be used to carry data from the Device to the Reader, or can be used to carry control information from the Device to the Reader, for example, including physical layer control information (such as ACI) and / or high layer control information (such as MAC-CE). Optionally, in addition to the preamble, the R2D transmission and the D2R transmission can also support midamble and postamble. For example, the midamble is inserted in the transmission of PRDCH or PDRCH. For example, the postamble is inserted after the end of the transmission of PRDCH or PDRCH.
[0119] FIGS. 8, 9 and 10 respectively analyze the interference between R2D or D2R transmission and NR UL or NR DL transmission when the NR Uu system and the A-IoT system are deployed simultaneously. The present application mainly aims at the interference problem in FIG. 10, and designs a mechanism for the first communication device to report transmission conflict, so as to solve the above inter-system interference problem from the perspective of avoiding transmission conflict.
[0120] Please refer to FIG. 12, which shows a flowchart of the information reporting method provided by an embodiment of the present application. The method can be applied to the network architecture shown in FIGS. 1 and 6. The method can include the following step 1210.
[0121] At step 1210, the first communication device sends first information to the second communication device based on the first signal and / or the second signal, the first signal comprising a signal in the A-IoT system, the second signal comprising a signal in the cellular communication system, the first information being used to indicate a transmission conflict between the first signal and the second signal.
[0122] Correspondingly, the second communication device receives the first information sent by the first communication device based on the first signal and / or the second signal.
[0123] In some embodiments, the signal in the A-IoT system refers to an A-IoT signal for data transmission and interaction in the ambient Internet of Things, which carries information such as data exchange, instruction issuance, and state reporting between Internet of Things devices. Exemplarily, the signal in the A-IoT system can include a signal for R2D transmission in the A-IoT system, a signal for D2R transmission in the A-IoT system, and a carrier signal. In some embodiments, the signal in the cellular communication system refers to a wireless signal for realizing mobile phone communication, data transmission, and Internet access under a cellular network architecture. The cellular communication system in the present application mainly takes the NR system as an example, but it is not limited to other types of cellular communication systems, such as LTE, B5G, 6G, etc. Exemplarily, the signal in the cellular communication system can include an NR signal, such as a signal for NR UL transmission and a signal for NR DL transmission.
[0124] In some embodiments, when the A-IoT system and the cellular communication system coexist, due to the fact that the signal in the A-IoT system and the signal in the cellular communication system can be transmitted in the same frequency spectrum range or time window, etc., there is a transmission conflict between the first signal and the second signal, thereby causing a problem of signal transmission quality decline. In the present application, the transmission conflict between the first signal and the second signal can be a conflict between R2D transmission and / or D2R transmission included in the A-IoT system and NR UL transmission included in the cellular communication system.
[0125] In some embodiments, due to the backscattering of the A-IoT device, the D2R transmission and the carrier transmission of the A-IoT can be performed at the same time. Therefore, in the present application, the conflict resolution mechanism between the D2R transmission and the NR UL transmission is also applicable to the conflict between the carrier transmission and the NR UL transmission.
[0126] The first communication device is configured to monitor transmission collision between the first signal and the second signal. When the first communication device determines that there is transmission collision between the first signal and the second signal, the first communication device is configured to timely send the first information to the second communication device, so that the second communication device can take appropriate measures based on the first information, such as instructing to retransmit the first signal or the second signal, thereby effectively reducing transmission collision between the A-IoT system and the cellular communication system and ensuring effective transmission of signals.
[0127] In summary, the technical scheme provided by the embodiments of the present application can flexibly determine transmission collision between the first signal and the second signal based on the first signal and / or the second signal, thereby effectively reducing transmission collision between the A-IoT system and the cellular communication system.
[0128] The following describes a specific implementation of the first communication device sending the first information to the second communication device based on the first signal and / or the second signal.
[0129] (1) The first signal includes a signal of R2D transmission in the A-IoT system
[0130] When the first signal includes a signal of R2D transmission in the A-IoT system, the second signal can be an NR UL signal. The specific implementation of sending the first information can be determined in the following two ways.
[0131] Method 1: After sending the signal of R2D transmission, if the first communication device does not receive D2R transmission corresponding to the R2D transmission, the first communication device sends the first information to the second communication device; or after sending the signal of R2D transmission, if the number of times that the first communication device does not receive D2R transmission corresponding to the R2D transmission is greater than or equal to a first threshold, the first communication device sends the first information to the second communication device.
[0132] In some embodiments, in the DO-DTT scenario, the A-IoT device can be triggered to report information by a downlink command. Specifically, the downlink command can be sent through R2D transmission, and the information reporting of the A-IoT device can be sent through D2R transmission. For example, the R2D transmission can be a query or query repeat instruction, and the D2R transmission can be RN16, where RN16 refers to a random sequence of length 16. For another example, the R2D transmission can be a response based on RN16, for example, a Reader sends a Response of RN16 to a Device after successfully receiving the RN16, and the D2R transmission can be an EPC (Electronic Product Code). In some embodiments, in the DT scenario, the Reader can trigger the Device to perform a corresponding operation through a downlink command. The Device sends feedback information to the Reader after successfully receiving the command or successfully performing the corresponding operation, and the feedback information is used to indicate whether the command is successfully received or the corresponding operation is successfully performed. For example, the R2D transmission can be a Command, and the D2R transmission can be a feedback of the Command, for example, used to indicate whether the Command is successfully received or successfully performed.
[0133] In some embodiments, after sending the signal of the R2D transmission, if the D2R transmission corresponding to the R2D transmission is not received within a preset time, the first communication device determines that the R2D transmission can be interfered by the NR UL transmission, and sends the first information to the second communication device. The preset time can be configured by the network, preconfigured, predefined by the standard, or determined by the first communication device.
[0134] In some embodiments, the first threshold value can be configured by the network, pre-configured, predefined by a standard, or dependent on the implementation of the first communication device, which is not limited in the present application. The first threshold value can be M, where M is a positive integer. The case that the number of times that the second communication device fails to receive the D2R transmission corresponding to the R2D transmission is greater than or equal to the first threshold value can include at least one of the following: among the last N R2D transmissions, there are M times that the corresponding D2R response is not received, where N is a positive integer greater than or equal to M; within a predetermined time window, there are M times that the corresponding D2R response is not received for the R2D transmission, where the predetermined time window refers to a preset time period; the number of times that the D2R response is not received is accumulated, and when the set first threshold value M is reached, it is determined that the R2D transmission is interfered by the NR UL transmission at this time. When the accumulated number of times reaches the first threshold value M, the first communication device sends the first information to the second communication device, and the number of times that the D2R response is not received is cleared to start counting again. The value of N and the length of the preset time period can be configured by the network, pre-configured, predefined by a standard, or dependent on the implementation of the first communication device, which is not limited in the present application.
[0135] The above method can timely and accurately determine that the R2D transmission is interfered by the NR UL transmission by monitoring the D2R transmission corresponding to the R2D transmission that is not received and determining that the number of times that the D2R response is not received reaches the first threshold value M, so that the second communication device can timely reschedule the R2D transmission or the NR UL transmission, thereby optimizing the transmission performance of the system.
[0136] In some embodiments, the signal of the R2D transmission is sent by a first read-write device, the first communication device is a second read-write device, and the second communication device is a network device, such as a base station. The second read-write device is different from the first read-write device. After the first read-write device sends the signal of the R2D transmission, the second read-write device sends the first information to the second communication device in the case that the second read-write device fails to receive the D2R transmission corresponding to the R2D transmission. In some embodiments, after the first read-write device sends the signal of the R2D transmission, the second read-write device sends the first information to the second communication device in the case that the number of times that the second read-write device fails to receive the D2R transmission corresponding to the R2D transmission is greater than or equal to the first threshold value. The first read-write device and the second read-write device can be intermediate nodes, and the second read-write device reporting the first information to the base station can also be understood as reporting through the NR UL.
[0137] In some embodiments, the signal of the R2D transmission is sent by the first read-write device, the first communication device is the first read-write device, and the second communication device is a network device, such as a base station. After sending the signal of the R2D transmission, the first read-write device sends the first information to the second communication device in the case that no D2R transmission corresponding to the R2D transmission is received. In some embodiments, after sending the signal of the R2D transmission, the first read-write device sends the first information to the second communication device in the case that the number of times that no D2R transmission corresponding to the R2D transmission is received is greater than or equal to a first threshold. The first read-write device described above can be an intermediate node, and the reporting of the first information by the first read-write device to the base station can be understood as reporting through NR UL.
[0138] Exemplarily, as shown in subgraph 2-1-A in FIG. 10, the first read-write device is Reader 1, and the second read-write device is Reader 2, that is, the sending end of the R2D transmission and the receiving end of the D2R transmission are not the same Reader. After sending the signal of the R2D transmission, Reader 1 sends the first information to the base station in the case that no D2R transmission corresponding to the R2D transmission is received by Reader 2. Exemplarily, after sending the signal of the R2D transmission, Reader 1 sends the first information to the base station in the case that the number of times that no D2R transmission corresponding to the R2D transmission is received by Reader 2 is greater than or equal to a first threshold.
[0139] Exemplarily, as shown in subgraph 2-2-A to subgraph 2-4-A in FIG. 10, the first read-write device is Reader, that is, the sending end of the R2D transmission and the receiving end of the D2R transmission are the same Reader. After sending the signal of the R2D transmission, the Reader sends the first information to the base station in the case that no D2R transmission corresponding to the R2D transmission is received by the Reader. Exemplarily, after sending the signal of the R2D transmission, the Reader sends the first information to the base station in the case that the number of times that no D2R transmission corresponding to the R2D transmission is received by the Reader is greater than or equal to a first threshold.
[0140] The method described above can flexibly determine the communication device that reports the first information. Specifically, when the sending end of the R2D transmission and the receiving end of the D2R transmission are the same Reader, the reporting of the first information is performed by the Reader; when the sending end of the R2D transmission and the receiving end of the D2R transmission are not the same Reader, the receiving end of the D2R transmission reports the first information to the second communication device when it is determined that the R2D transmission is interfered by the NR UL transmission. In this way, the first information can be timely and accurately transmitted to the second communication device in different scenarios, so that the interference problem can be more effectively handled.
[0141] The first information has at least one of the following functions: for rescheduling the transmission of the first signal, or rescheduling the transmission of the second signal; for indicating a transmission conflict; for determining the transmission resource corresponding to the first signal; for determining the transmission resource corresponding to the second signal. In some embodiments, the first information is for rescheduling the R2D transmission, or rescheduling the NR UL transmission.
[0142] In some embodiments, the first information is for determining the transmission resource corresponding to each of the first signal and / or the second signal. The transmission resource can include a time domain resource and / or a frequency domain resource. The time domain resource refers to a transmission resource that is divided and managed in time, and can be a time slot, a symbol, a frame, a subframe, etc. The frequency domain resource refers to a frequency range used for data transmission, and can be a subcarrier, a PRB (Physical Resource Block), etc. Illustratively, the first information can include time domain resource information of the transmitted R2D transmission, such as a time slot corresponding to the R2D transmission; the first information can include frequency domain resource information of the transmitted R2D transmission, such as a PRB corresponding to the R2D transmission.
[0143] In some embodiments, the first information is request scheduling information or conflict indication information. Illustratively, the first information includes a first bit, which is used to indicate whether to reschedule the R2D transmission or the NR UL transmission. When the first bit is used to indicate rescheduling the R2D transmission or the NR UL transmission, the specific way of scheduling the R2D transmission or the NR UL transmission and the detailed content of the scheduling depend on the implementation of the network device. In some embodiments, the first information includes transmission resource information of the R2D transmission that has been transmitted and for which no corresponding D2R transmission has been received, and can include time domain resource information or time-frequency resource information, such as a time slot or a time period corresponding to the R2D transmission that has been transmitted and for which no corresponding D2R transmission has been received. Illustratively, the second communication device determines the time of the conflict according to the transmission resource information included in the first information, such as determining the time of the conflict according to the reported time slot or time period, so as to reschedule the R2D transmission or the NR UL transmission that conflicts in the time period.
[0144] The above method can indicate the transmission conflict, resource requirement and scheduling request through the first information, so that the base station can accurately determine and schedule the transmission resource, reschedule the R2D transmission and the NR UL transmission, and ensure the efficiency and reliability of network transmission.
[0145] Method 2: In a case where the signal of the R2D transmission and the second signal satisfy a first condition, the first communication device sends first information to the second communication device.
[0146] In some embodiments, the first condition comprises at least one of: the signal of the R2D transmission and the second signal exist time domain and / or frequency domain overlap; the measurement result corresponding to the signal of the R2D transmission is greater than or equal to a second threshold; the measurement result corresponding to the second signal is greater than or equal to a third threshold; the difference or ratio between the first measurement result and the second measurement result is greater than or equal to a fourth threshold, the first measurement result being the larger one of the measurement result corresponding to the signal of the R2D transmission and the measurement result corresponding to the second signal, and the second measurement result being the smaller one of the measurement result corresponding to the signal of the R2D transmission and the measurement result corresponding to the second signal.
[0147] (a1) the signal of the R2D transmission and the second signal exist time domain and / or frequency domain overlap
[0148] The signal of the R2D transmission and the second signal exist time domain and / or frequency domain overlap means that the signal of the R2D transmission and the second signal have the same resource occupation area in time and / or frequency. That is, the signal of the R2D transmission and the second signal have intersection in transmission time period and / or frequency range, which will cause signal interference or resource competition.
[0149] In some embodiments, determining the time domain and / or frequency domain resource locations of the signal of the R2D transmission and the second signal respectively can comprise the following. For example, the first communication device can obtain the time domain and / or frequency domain resource locations of the NR UL transmission through resource indication information in DCI (Downlink Control Information) or UCI (Uplink Control Information). For example, the first communication device can determine the time domain and / or frequency domain resource locations of the NR UL transmission through measuring pilot signals such as DMRS (Demodulation Reference Signal) or SRS (Sounding Reference Signal). For example, by detecting the time slot or PRB of the pilot signal, it is determined that there is an NR UL signal in the time slot or PRB. For example, the first communication device can obtain the time domain and / or frequency domain resource locations of the R2D transmission through resource indication information in the control information in the ACI or PRDCH. For example, the first communication device can obtain the time domain and / or frequency domain resource locations of the R2D transmission through detecting a preamble. For example, by detecting the preamble, the starting time domain and / or frequency domain location and the transmission length of the R2D transmission are obtained. Specifically, the preamble can comprise a delimiter. Different forms of the delimiter can indicate the starting time domain and / or frequency domain location of the R2D transmission. For example, the different forms of the delimiter can be a continuous low level or a continuous high level or a high-low level switching or a low-high level switching. When the first communication device detects the delimiter in the above forms, it can determine the starting time domain and / or frequency domain location of the R2D transmission. For the transmission length of the R2D transmission, it can be obtained according to the corresponding relationship between the preamble and the transmission length. The first communication device is a Reader or a carrier node. For more information about the Reader and the carrier node, please refer to the following content.
[0150] (b1) the measurement result corresponding to the signal of the R2D transmission is greater than or equal to a second threshold
[0151] In some embodiments, the measurement result corresponding to the signal of the R2D transmission is related to at least one of the following: a measurement result of a preamble corresponding to the R2D transmission; a measurement result of a midamble corresponding to the R2D transmission; a measurement result of a postamble corresponding to the R2D transmission; a measurement result of a first channel corresponding to the R2D transmission; a measurement result on a time domain resource corresponding to the R2D transmission.
[0152] Specifically, when determining the measurement result corresponding to the signal of the R2D transmission, the measurement result can involve the performance of a specific part (preamble, midamble and postamble) in the signal of the R2D transmission. The preamble is located at the beginning of the R2D transmission and can be used to help the receiving end to synchronize and obtain the starting point of the transmission, and can represent the quality and intensity of the signal at the beginning of the transmission. The midamble refers to a specific signal inserted in the middle part of the R2D transmission, which can represent the quality of the signal at the middle of the transmission. The postamble is located at the end of the R2D transmission, which can represent the state of the signal at the end of the transmission, so as to understand the final effect of the whole transmission process. According to the measurement results of different parts, information about the quality and intensity of the signal at different transmission stages can be provided, thereby helping to more comprehensively evaluate the overall performance of the R2D transmission.
[0153] The first channel is the PRDCH, and the measurement result of the first channel can be the measured received power of the PRDCH. The measurement result on the time domain resource corresponding to the R2D transmission refers to the received power, signal-to-noise ratio or other related indicators obtained by measuring the R2D transmission signal or all signals (for example, including R2D signals and / or NR UL signals) on the time domain resource corresponding to the R2D transmission, which is used to represent the signal intensity of the R2D transmission signal or all signals on the time domain resource. Illustratively, the measurement result on the time domain resource corresponding to the R2D transmission can be the received power on the time domain resource occupied by the R2D transmission, for example, the average received power.
[0154] The second threshold value can be set as a reference value of the signal intensity of the R2D transmission, and the signal intensity can include the measured received power. In some embodiments, if the signal intensity of the R2D transmission is higher than the second threshold value, it indicates that the signal intensity of the R2D transmission is too high, that is, the signal of the R2D transmission can cause interference to the NR UL transmission signal. It can be understood that the greater the signal intensity of the R2D transmission, the more serious the interference to the NR UL transmission. In other embodiments, if the received power of the time domain resource corresponding to the R2D transmission is higher than the second threshold value, it indicates that there can be a transmission signal of the NR UL in addition to the R2D transmission, that is, the transmission signal of the NR UL and the signal of the R2D transmission can interfere with each other.
[0155] (c1) the measurement result corresponding to the second signal is greater than or equal to a third threshold value
[0156] In some embodiments, the measurement corresponding to the second signal is related to at least one of: a measurement of a pilot signal corresponding to the second signal; a measurement within a time domain unit corresponding to the second signal. Illustratively, the second signal comprises a NR UL signal. Illustratively, the pilot signal can be a measurement of a pilot signal corresponding to the NR UL signal. Illustratively, the pilot signal can be a DMRS or a SRS, and the measurement of the pilot signal can be a RSRP (Reference Signal Receiving Power). Illustratively, the time domain unit can be a slot, and the measurement within the time domain unit can be a RSSI (Received Signal Strength Indication) within a slot corresponding to the NR UL signal.
[0157] The third threshold value can be set as a reference value of a signal strength corresponding to the second signal. In some embodiments, the signal strength can comprise the RSRP measured above. If the signal strength of the NR UL transmission is higher than the second threshold value, it indicates that the signal strength of the NR UL transmission is too high, i.e. the signal of the NR UL transmission can interfere with the R2D transmission signal. It can be understood that the greater the signal strength of the NR UL transmission, the more serious the interference to the R2D transmission. In other embodiments, the signal strength can comprise the RSSI measured above. If the RSSI measured within a slot corresponding to the NR UL is greater than the second threshold value, it indicates that there can be A-IoT transmission signals in the slot, i.e. there can be mutual interference between the NR UL transmission signal and the A-IoT transmission signal.
[0158] (d1) the difference or ratio between the first measurement and the second measurement is greater than or equal to a fourth threshold value
[0159] The difference or ratio between the first measurement result and the second measurement result is used to represent the difference in signal strength between the R2D transmission signal and the second signal, which can be expressed as the first measurement result minus the second measurement result or the first measurement result divided by the second measurement result. The fourth threshold value mentioned above refers to a threshold value of the difference in signal strength, which is used to determine whether the difference in signal strength between the R2D transmission signal and the second signal is significant. Exemplarily, assuming that the measurement result corresponding to the R2D transmission signal is greater than the measurement result corresponding to the second signal, the difference or ratio between the first measurement result and the second measurement result can be the received power of the R2D transmission signal minus or divided by the RSRP of the NR UL. It can be understood that the greater the difference or ratio between the first measurement result and the second measurement result, the more significant the difference in signal strength between the R2D transmission signal and the second signal. When the difference or ratio between the first measurement result and the second measurement result is greater than the fourth threshold value, it can be considered that the first measurement result is greater at this time, and when the first measurement result is the measurement result corresponding to the R2D transmission signal, the R2D transmission signal can interfere with the NR UL transmission signal at this time; when the first measurement result is the measurement result corresponding to the second signal, the NR UL transmission signal can interfere with the R2D transmission signal at this time.
[0160] In some embodiments, the condition d1 mentioned above can also be that the difference or ratio between the first measurement result and the second measurement result after adding noise is greater than or equal to the fourth threshold value, where the second measurement result after adding noise is the sum of the first noise and the second measurement result. Exemplarily, the first noise can be N0, and the difference or ratio between the first measurement result and the second measurement result after adding noise can be expressed as the first measurement result minus (the second measurement result + N0) or the first measurement result divided by (the second measurement result + N0). Since the SINR represents the ratio of signal strength to noise plus interference, the ratio between the first measurement result and the second measurement result after adding noise (the first measurement result divided by (the second measurement result + N0)) can be regarded as the SINR measured by the first communication device, that is, the condition d1 mentioned above can also include that the SINR measured by the first communication device is greater than or equal to the fourth threshold value.
[0161] The second threshold value, the third threshold value and the fourth threshold value mentioned above can be configured by the network, can be preconfigured, can be predefined by the standard, or can depend on the implementation of the first communication device, and the present application does not limit this.
[0162] The method mentioned above can timely and accurately determine whether the R2D transmission interferes with the NR UL transmission through the first condition.
[0163] In some embodiments, the signal of the R2D transmission is sent by the first read-write device, the first communication device is a second read-write device, and the second communication device is a network device, such as a base station. The second read-write device is different from the first read-write device. In a case where the signal of the R2D transmission and the second signal satisfy the first condition, the second read-write device sends the first information to the second communication device. The second read-write device can be an intermediate node, and the reporting of the first information by the second read-write device to the base station can be understood as reporting through NR UL.
[0164] In some embodiments, the signal of the R2D transmission is sent by the first read-write device, the first communication device is a carrier node, and the second communication device is a network device, such as a base station. In a case where the signal of the R2D transmission and the second signal satisfy the first condition, the carrier node sends the first information to the second communication device. The carrier node can be a base station or a terminal device. When the carrier node is a base station, the reporting of the first information by the carrier node to the base station can be understood as an interaction between base stations, such as reporting by a small base station to a macro base station, or reporting by a base station acting as a Reader to a base station performing NR transmission. When the carrier node is a terminal device, the reporting of the first information by the carrier node to the base station can be understood as reporting through NR UL.
[0165] For example, as shown in subgraph 2-1-A of FIG. 10, the first read-write device is Reader 1, and the second read-write device is Reader 2, i.e., the sending end of the R2D transmission and the receiving end of the D2R transmission are not the same Reader. Reader 1 sends the signal of the R2D transmission, and Reader 2 is not used for transmission. In a case where the signal of the R2D transmission and the second signal satisfy the first condition, Reader 2 sends the first information to the base station.
[0166] For example, as shown in subgraph 2-3-A of FIG. 10, the first read-write device is a Reader, and the Reader sends the signal of the R2D transmission. In this case, the carrier node is not used for transmission. In a case where the signal of the R2D transmission and the second signal satisfy the first condition, the carrier node sends the first information to the base station. For related content of the first information, please refer to the description of the above method 1.
[0167] The above method can flexibly determine the communication device that reports the first information. This ensures that the first information can be timely and accurately delivered to the second communication device in different scenarios, thereby more effectively handling interference problems.
[0168] The first condition can include any one of a1, b1, c1, and d1, the first condition can include a1 and b1, the first condition can include a1 and c1, and the first condition can include a1 and d1. The present application does not limit this. Exemplarily, the first condition includes a1 and c1. As shown in subgraph 2-1-A of FIG. 10, the first communication device is Reader 2. Since the measurement result corresponding to the second signal, i.e., the NR UL transmission signal, is greater than or equal to the third threshold value, Reader 2 considers that the NR UL transmission has a large interference on the R2D transmission, and then reports the first information. Optionally, the first information includes 1-bit scheduling request information. After receiving the first information, the base station re-schedules the R2D transmission or re-schedules the NR UL transmission. Optionally, the first information includes time domain position information of the R2D transmission sent by Reader 1 and overlapping in time domain with the NR UL. For example, the time domain position information is one or more time slots or one or more time ranges. After receiving the time slot or time range reported by the base station, the base station can determine the time slot or time range in which the transmission conflict occurs, and then re-schedule the R2D transmission or re-schedule the NR UL transmission. Optionally, the first information includes time domain position information of the NR UL transmission overlapping in time domain with the R2D transmission, for example, one or more time slots. After receiving the first information, the base station can determine the time slot in which the transmission conflict occurs, and then re-schedule the R2D transmission or re-schedule the NR UL transmission.
[0169] Exemplarily, the first condition includes a1 and c1. As shown in subgraph 2-3-A of FIG. 10, the first communication device is a carrier node. Since the measurement result corresponding to the second signal, i.e., the NR UL transmission signal, is greater than or equal to the third threshold value, the carrier node considers that the NR UL transmission has a large interference on the R2D transmission, and then reports the first information.
[0170] The above method can indicate the transmission conflict, resource requirement, and scheduling request through the first information, so that the base station can accurately determine and schedule the transmission resource, re-schedule the R2D transmission and the NR UL transmission, and ensure the efficiency and reliability of the network transmission.
[0171] (2) The first signal includes a signal of D2R transmission in an A-IoT system
[0172] In some embodiments, the second signal can be an NR UL signal. In a case where the signal of the D2R transmission and the second signal satisfy a second condition, the first communication device sends first information to the second communication device.
[0173] In some embodiments, the second condition comprises at least one of: the D2R-transmitted signal and the second signal exist time-domain and / or frequency-domain overlap; a measurement result corresponding to the D2R-transmitted signal is greater than or equal to a fifth threshold; a measurement result corresponding to the second signal is greater than or equal to a sixth threshold; a difference or a ratio between a third measurement result and a fourth measurement result is greater than or equal to a seventh threshold, the third measurement result being a larger one of the measurement result corresponding to the D2R-transmitted signal and the measurement result corresponding to the second signal, and the fourth measurement result being a smaller one of the measurement result corresponding to the D2R-transmitted signal and the measurement result corresponding to the second signal.
[0174] (a2) the D2R-transmitted signal and the second signal exist time-domain and / or frequency-domain overlap
[0175] The D2R-transmitted signal and the second signal exist time-domain and / or frequency-domain overlap means that the D2R-transmitted signal and the second signal have the same resource occupation area in time and / or frequency. That is, the D2R-transmitted signal and the second signal exist intersection in transmission time period and / or frequency range, which will cause signal interference or resource competition.
[0176] In some embodiments, determining the time-domain and / or frequency-domain resource location of the D2R-transmitted signal and the second signal respectively can comprise the following manners. Exemplarily, the first communication device can obtain the time-domain and / or frequency-domain resource location of the NR UL transmission through resource indication information in DCI or UCI. Exemplarily, the first communication device can determine the time-domain and / or frequency-domain resource location of the NR UL transmission through measuring pilot signals such as DMRS or SRS. For example, by detecting the time slot or PRB of the pilot signal, it is determined that there is an NR UL signal in the time slot or PRB. Exemplarily, the first communication device can obtain the time-domain and / or frequency-domain resource location of the D2R transmission through resource indication information in the control information in the ACI or PDRCH or PRDCH. Exemplarily, the first communication device can obtain the time-domain and / or frequency-domain resource location of the D2R transmission through detecting preamble. For example, by detecting the preamble, the starting time-domain and / or frequency-domain location and the transmission length of the D2R transmission are obtained. Similarly, the preamble can indicate the starting time-domain and / or frequency-domain location of the D2R transmission through different forms of delimiter. Exemplarily, the different forms of delimiter can be continuous low level or continuous high level or high-low level switching or low-high level switching, and when the first communication device detects the delimiter in the above forms, the starting time-domain and / or frequency-domain location of the D2R transmission can be determined. For the transmission length of the D2R transmission, it can be obtained according to the corresponding relationship between the preamble and the transmission length. The above first communication device is a Reader, and more information about the Reader can be found in the following content.
[0177] (b2) the measurement result corresponding to the signal of the D2R transmission is greater than or equal to a fifth threshold value
[0178] In some embodiments, the measurement result corresponding to the signal of the D2R transmission is related to at least one of: a measurement result of a preamble corresponding to the D2R transmission; a measurement result of a midamble corresponding to the D2R transmission; a measurement result of a postamble corresponding to the D2R transmission; a measurement result of a second channel corresponding to the D2R transmission; a measurement result on a time domain resource corresponding to the D2R transmission.
[0179] Specifically, when determining the measurement result corresponding to the signal of the D2R transmission, the measurement result relates to the performance of a specific part (preamble, midamble and postamble) in the signal of the D2R transmission. For related content of the preamble, midamble and postamble, please refer to the related content in b1 above.
[0180] The second channel is the PDRCH, and the measurement result of the second channel can be the measured received power of the PDRCH. The measurement result on the time domain resource corresponding to the D2R transmission refers to the received power, signal-to-noise ratio or other related indicators obtained by measuring the D2R transmission signal or all signals (for example, including the D2R signal and / or the NR UL signal) on the time domain resource corresponding to the D2R transmission, which is used to represent the signal strength of the D2R transmission signal or all signals on the time domain resource. Exemplarily, the measurement result on the time domain resource corresponding to the D2R transmission can be the received power on the time domain resource occupied by the D2R transmission, for example, the average received power.
[0181] The fifth threshold value can be set as a reference value of the signal strength corresponding to the D2R transmission, and the signal strength can include the measured received power. In some embodiments, if the signal strength of the D2R transmission is higher than the fifth threshold value, it indicates that the signal strength of the D2R transmission is too high, that is, the signal of the D2R transmission can cause interference to the NR UL transmission signal. It can be understood that the greater the signal strength of the D2R transmission, the more serious the interference to the NR UL transmission. In other embodiments, if the received power of the time domain resource corresponding to the D2R transmission is higher than the fifth threshold value, it indicates that there can be a transmission signal of the NR UL in addition to the D2R transmission, that is, the transmission signal of the NR UL and the signal of the D2R transmission can interfere with each other.
[0182] (c2) the measurement result corresponding to the second signal is greater than or equal to a sixth threshold value
[0183] In some embodiments, the measurement result corresponding to the second signal is related to at least one of: a measurement result of a pilot signal corresponding to the second signal; a measurement result within a time domain unit corresponding to the second signal. For related content, please refer to the related content in c1 above.
[0184] (d2) a difference or a ratio between the third measurement result and the fourth measurement result is greater than or equal to a seventh threshold value
[0185] The difference or the ratio between the third measurement result and the fourth measurement result is used to represent the difference of signal strength between the signal of the D2R transmission and the second signal, which can be expressed as the third measurement result minus the fourth measurement result or the third measurement result divided by the fourth measurement result. The above-mentioned seventh threshold value refers to a threshold value of the difference of signal strength, which is used to determine whether the difference of signal strength between the signal of the D2R transmission and the second signal is significant. Exemplarily, assuming that the measurement result corresponding to the signal of the D2R transmission is greater than the measurement result corresponding to the second signal, the difference or the ratio between the third measurement result and the fourth measurement result can be the received power of the D2R transmission minus or divided by the RSRP of the NR UL. It can be understood that the greater the difference or the ratio between the third measurement result and the fourth measurement result, the more significant the difference of signal strength between the signal of the D2R transmission and the second signal. When the difference or the ratio between the third measurement result and the fourth measurement result is greater than the seventh threshold value, it can be considered that the third measurement result is greater at this time, and when the third measurement result is the measurement result corresponding to the signal of the D2R transmission, the signal of the D2R transmission can interfere with the NR UL transmission signal at this time; when the third measurement result is the measurement result corresponding to the second signal, the signal of the NR UL transmission can interfere with the signal of the D2R transmission at this time.
[0186] In some embodiments, the above-mentioned condition d2 can also be that a difference or a ratio between the third measurement result and a noise-added fourth measurement result is greater than or equal to a seventh threshold value, wherein the noise-added fourth measurement result is a sum of the second noise and the fourth measurement result. Exemplarily, the second noise can be N1, and the difference or the ratio between the third measurement result and the sum of the fourth measurement result and the second noise can be expressed as the third measurement result minus (the fourth measurement result+N1) or the third measurement result divided by (the fourth measurement result+N1). Similarly, the ratio between the third measurement result and the noise-added fourth measurement result (the third measurement result / (the fourth measurement result+N1)) can be regarded as the SINR measured by the first communication device, that is, the above-mentioned condition d2 can also include that the SINR measured by the first communication device is greater than or equal to the seventh threshold value.
[0187] The above-mentioned fifth threshold value, the sixth threshold value and the seventh threshold value can be configured by the network, can be preconfigured, can be predefined by the standard, or can depend on the implementation of the first communication device, which is not limited in the present application.
[0188] The above-mentioned method can timely and accurately determine whether the D2R transmission interferes with the NR UL transmission through the second condition.
[0189] In some embodiments, the D2R-transmitted signal is transmitted by the first A-IoT device, and the first communication device is a read-write device receiving the D2R-transmitted signal. The second communication device is a network device, such as a base station. In the case where the D2R-transmitted signal and the second signal satisfy the second condition, the read-write device receiving the D2R-transmitted signal transmits first information to the second communication device. Where the read-write device receiving the D2R-transmitted signal is an intermediate node, the read-write device reporting the first information to the base station can be understood as reporting through NR UL.
[0190] Exemplarily, as shown in subgraphs 2-1-B to 2-4-B in FIG. 10, the Device, i.e., the first A-IoT device, receives the D2R-transmitted signal from Reader 2 (corresponding to subgraph 2-1-B) or Reader (corresponding to subgraphs 2-2-B to 2-4-B). The first A-IoT device transmits the D2R-transmitted signal. For subgraph 2-1-B, Reader 2 is in a receiving state at this time, and for subgraphs 2-2-B to 2-4-B, Reader is in a receiving state at this time. When Reader 2 or Reader determines that the D2R-transmitted signal and the second signal satisfy the second condition, first information is transmitted to the second communication device.
[0191] In some embodiments, the first information is used to reschedule the D2R transmission or reschedule the NR UL transmission. In some embodiments, the first information is also used to indicate the transmission conflict. The first information can include time domain resource information of the transmitted D2R transmission, such as a time slot or a time period corresponding to the D2R transmission; the first information can include frequency domain resource information of the transmitted D2R transmission, such as a PRB corresponding to the D2R transmission. In some embodiments, the first information can also include time domain resource information and / or frequency domain resource information of the NR UL transmission, for example, can include a time slot or a PRB corresponding to the NR UL transmission.
[0192] In some embodiments, the first information is request scheduling information or conflict indication information. Exemplarily, the first information includes a first bit, which is used to indicate whether to reschedule the D2R transmission or reschedule the NR UL transmission. When the first bit is used to indicate rescheduling the D2R transmission or the NR UL transmission, the specific way of scheduling the D2R transmission or the NR UL transmission and the detailed content of the scheduling depend on the implementation of the network device. Exemplarily, the second communication device determines the time of the conflict according to the time domain resource information and / or the frequency domain resource information included in the first information, such as the second communication device determines the time of the conflict according to the reported time slot or time period, so as to reschedule the D2R transmission or the NR UL transmission that has a conflict in the time period. For more information about the first information, please refer to the description of the above-mentioned manner 1.
[0193] The second condition can include any one of a2, b2, c2, d2, the second condition can include a2 and b2, the second condition can include a2 and c2, and the second condition can include a2 and d2. The present application does not limit this. Exemplarily, the second condition includes a2 and c2. As shown in subgraph 2-1-B of FIG. 10, the first communication device is Reader 2. Since the measurement result corresponding to the second signal, i.e., the NR UL transmission signal, is greater than or equal to the sixth threshold value, Reader 2 considers that the NR UL transmission has great interference on the D2R transmission, and then reports the first information. Similarly, as shown in subgraphs 2-2-B to 2-4-B of FIG. 10, the first communication device is Reader. Since the measurement result corresponding to the second signal, i.e., the NR UL transmission signal, is greater than or equal to the sixth threshold value, Reader considers that the NR UL transmission has great interference on the D2R transmission, and then reports the first information. Optionally, the first information contains 1-bit request scheduling information. After the base station receives the first information, the base station reschedules the D2R transmission or reschedules the NR UL transmission. Optionally, the first information contains the time domain position information of the D2R transmission sent by the Device (i.e., the first A-IoT device) and having time domain overlap with the NR UL. For example, the time domain position information is one or more time slots or one or more time ranges. After the base station receives the time slot or the time range, the base station can determine the time slot or the time period in which the transmission conflict occurs according to the reported time slot or time range, and then reschedule the D2R transmission or reschedule the NR UL transmission. Optionally, the first information contains the time domain position information of the NR UL transmission having time domain overlap with the D2R transmission, for example, one or more time slots. After the base station receives the first information, the base station can determine the time slot in which the transmission conflict occurs according to the reported time slot, and then reschedule the D2R transmission or reschedule the NR UL transmission.
