With the popularization of Internet of Things devices, infrared technology, as a wireless communication method, is increasingly being used in Internet of Things devices to achieve real-time perception of the environment and data collection. Infrared technology is a remote sensing technology that does not require contact or contact. It uses infrared radiation emitted or reflected by the object itself to transmit information. In the Internet of Things environment, infrared devices can detect and analyze factors such as temperature, humidity, and light in the surrounding environment in real time, thereby providing users with real-time environmental data and intelligent control services. Infrared Internet of Things devices have the advantages of easy installation, low cost, high stability, and strong anti-electromagnetic interference ability.

[0036] To facilitate understanding of the technical solutions provided by the embodiments of the present application, a brief introduction to the related technologies of the present application is first given. The brief introduction is as follows:

[0037] 1. Beam:

[0038] With the development of the fifth generation (5G) mobile communication system, the spectrum used has gradually evolved to the high frequency band. Due to the physical transmission characteristics, the free space transmission loss and penetration loss in the high frequency band will be significantly higher than that in the low frequency band. In order to make up for the above disadvantages, the transmitter or receiver of the network equipment or terminal concentrates the energy in a narrow range through the antenna array to form a special directional transmission or reception effect, that is, a beam, which is similar to the beam formed by a flashlight converging light in one direction. Sending and receiving signals in the form of beams can effectively counteract the signal attenuation caused by losses and effectively increase the transmission distance of the signal, thereby effectively improving network coverage and user experience rate.

[0039] The beam can be a wide beam, a narrow beam or other types of beams. Among them, a wide beam refers to concentrating limited transmission energy in a wider direction to take into account the transmission distance and coverage width of the beam. A narrow beam refers to concentrating limited transmission energy in a narrower direction to further increase the transmission distance of the beam. The technology for forming the beam can be beamforming technology or other technologies. The beamforming technology can specifically be digital beamforming technology, analog beamforming technology or hybrid digital / analog beamforming technology.

[0040] Beams generally correspond to resources. For example, when performing beam measurement, the network device measures different beams through different resources, and the terminal feeds back the measured resource quality, so that the network device can know the quality of the corresponding beam. During data transmission, the beam can also be indicated by its corresponding resource. For example, the network device indicates a transmission configuration indication-state through the transmission configuration index (TCI) field in the downlink control information (DCI), and the terminal determines the beam corresponding to the reference resource based on the reference resource contained in the TCI-state.

[0041] In the communication protocol, the beam can be specifically characterized as a digital beam, an analog beam, a spatial domain filter, a spatial filter, a spatial parameter, TCI, a TCI-state, etc. The beam used to send a signal can be called a transmission beam (or Tx beam), a spatial domain transmission filter, a spatial transmission filter, a spatial domain transmission parameter, a spatial transmission parameter, etc. The beam used to receive a signal can be called a reception beam (or Rx beam), a spatial domain reception filter, a spatial reception filter, a spatial domain reception parameter, a spatial reception parameter, etc.

[0042] It can be understood that the embodiments of the present application are uniformly described using beams, but beams can be replaced by other equivalent concepts and are not limited to the concepts mentioned above.

[0043] 2. Resources:

[0044] In the communication protocol, reference signals are configured in the form of resources. Network equipment will configure each reference signal to the terminal in the form of resources. A resource is a configuration information unit, which usually includes parameters related to a reference signal, such as the time-frequency resource location of the reference signal, the number of ports, the time domain type (periodic / semi-static / aperiodic), etc.

[0045] The resources may be uplink signal resources or downlink signal resources. Uplink signals include but are not limited to sounding reference signals (SRS) and demodulation reference signals (DMRS). Downlink signals may include but are not limited to channel state information reference signals (CSI-RS), cell specific reference signals (CS-RS), user equipment specific reference signals (US-RS), demodulation reference signals (DMRS), and synchronization system / physical broadcast channel blocks (SS / PBCH block). SS / PBCH block may be referred to as synchronization signal block (SSB).

[0046] Resources can be configured through radio resource control (RRC) messages. In terms of configuration structure, a resource is a data structure, including relevant parameters of its corresponding uplink / downlink signal. For example, the type of uplink / downlink signal, the resource element carrying the uplink / downlink signal, the transmission time and period of the uplink / downlink signal, the number of ports used to send the uplink / downlink signal, etc. Each resource of the uplink / downlink signal has a unique identifier to identify the resource of the downlink signal. It can be understood that the identifier of the resource can also be referred to as the identifier of the resource, and the embodiments of the present application do not impose any restrictions on this.

[0047] 3. Antenna panel:

[0048] The antenna panel may refer to the antenna panel of a network device or the antenna panel of a terminal. An antenna panel generally has one or more antennas, which are arranged into an antenna array to perform beamforming to form a simulated beam. The antenna array can generate simulated beams pointing in different directions. In other words, multiple simulated beams can be formed on each antenna panel, and beam measurement can be used to determine which simulated beam is best for the antenna panel. In the embodiments of the present application, unless otherwise specified, the antenna panel refers to the antenna panel of the terminal.

[0049] In the communication protocol, the antenna panel may be represented by a panel, a panel index, etc., or the antenna panel may be implicitly represented by other means. For example, the antenna panel may also be characterized by an antenna port (such as a CSI-RS port, an SRS port, a DMRS port, a phase-tracking reference signal (PTRS) port, a cell reference signal (CRS) port, a tracking reference signal (TRS) port, or an SSB port, etc.) or an antenna port group, etc., or by resources (such as CSI-RS resources, SRS resources, DMRS resources, PTRS resources, CRS resources, TRS resources, SSB resources, etc.) or a resource group, or by a channel (such as a physical uplink control channel (PUCCH), a physical uplink shared channel (PUSCH), a physical random access channel (PRACH), a PDSCH, a physical downlink control channel (PDCCH), or a physical broadcast channel (PDCCH). channel, PBCH), etc.), can also be characterized by beams, such as quasi-co-location (QCL), TCI-state, spatial relationship, or a certain identifier configured in QCL, TCI-state, spatial relationship, can also be characterized by beam groups, such as QCL groups, TCI-state groups, or spatial relationship groups, etc., can also be characterized by a terminal capability parameter set reported by the terminal (there is a corresponding relationship between the terminal capability parameter set and the antenna panel). A terminal capability parameter set includes the relevant terminal capabilities corresponding to an antenna panel. For example, it includes the maximum number of transmission layers, the maximum number of SRS ports, and the maximum transmission power corresponding to an antenna panel. That is to say, the antenna panel mentioned in the embodiment of the present application can also be replaced by the above content.

[0050] The terminal can be equipped with multiple antenna panels. These antenna panels can be distributed in different positions and facing different directions, which can ensure that no matter which direction the terminal faces, at least one antenna panel is facing the network device and can transmit data with the network device.

Figure 1 Schematic diagram of a communication system architecture applicable to the IoT device anti-interference method provided in the embodiment of the present application Figure 1 .

[0058] like Figure 1 As shown, the communication system may include: a terminal and a network device.

[0059] The above-mentioned terminal may be a terminal with transceiver functions, or a chip or chip system that can be set in the terminal. The terminal may also be called user equipment (UE), access terminal, subscriber unit, user station, mobile station (MS), mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device.

Alternatively, the terminal may also be customer-premises equipment (CPE).

[0060] In the embodiment of the present application, the specific form of the terminal may be an Internet of Things device, the Internet of Things device is provided with a first antenna panel, the beam direction of the first antenna panel points to the infrared detection direction of the Internet of Things device. In addition, the Internet of Things device is also provided with a second antenna panel, the beam direction of the second antenna panel is opposite to the infrared detection direction of the Internet of Things device.

[0061] The above-mentioned network equipment may be an access network (AN) equipment, or may be referred to as a radio access network (RAN) equipment. RAN equipment may provide access functions for the terminal, and is responsible for functions such as radio resource management, quality of service (QoS) management, data compression and encryption on the air interface side.

Alternatively, the RAN device may also include an access point (AP) in a wireless fidelity (WiFi) system, a wireless relay node, a wireless backhaul node, various forms of macro base stations, micro base stations (also called small stations), relay stations, access points, wearable devices, vehicle-mounted devices, etc. Alternatively, the RAN device may also include a next-generation mobile communication system, such as a 6G access network device, such as a 6G base station, or in the next-generation mobile communication system, the network device may also have other naming methods, which are all covered within the protection scope of the embodiments of the present application, and the present application does not make any limitation on this.

[0062] For example, Figure 2 Schematic diagram of the process of the anti-interference method of the Internet of Things device provided in the embodiment of the present application Figure 1 The method can be applied to the communication between the network device and the terminal in the above communication system, and the specific form of the terminal can be an Internet of Things device.

[0063] like Figure 2 As shown, the process of the anti-interference method of the IoT device is as follows:

[0064] S201, the Internet of Things device determines the channel quality of the first channel through the beam of the first antenna panel.

[0065] The first channel is a channel pointing in the infrared detection direction of the IoT device.

[0066] For example, the IoT device can receive the first downlink signal from the network device through the receiving beam of the first antenna panel. The network device is a network device to which the IoT device is connected, and can be understood as an access network device. The IoT device can determine the channel quality of the first channel based on the first downlink signal, such as the channel quality indicator (CQI), which indicates the quality of the first channel, and its value range is 0 to 31. When the CQI value is 0, the channel quality is the worst; when the CQI value is 31, the channel quality is the best.

[0067] Optionally, the receiving beam includes M receiving beams pointing to different directions, where M is greater than 1. Then, the IoT device can receive the first downlink signals from the network device respectively through the M receiving beams of the first antenna panel, and there are a total of M first downlink signals, and the M receiving beams correspond one-to-one to the M first downlink signals. The IoT device determines the channel quality of each of the M first channels based on the M first downlink signals, and the M first downlink signals correspond one-to-one to the M first channels.

[0068] For example, Figure 3 As shown, the M receiving beams include receiving beam #1, receiving beam #2, receiving beam #3, receiving beam #4, and receiving beam #5. The IoT device first uses receiving beam #1 to receive the first downlink signal in the order of the beam numbers from small to large to measure the channel quality of the first channel #1, and then uses receiving beam #2 to receive the first downlink signal to measure the channel quality of the first channel #2, and so on, until receiving beam #5 is used to receive the first downlink signal to measure the channel quality of the first channel #5. In this case, the CQI of the first channel #1 is 24, the CQI of the first channel #2 is 5, the CQI of the first channel #3 is 13, the CQI of the first channel #4 is 16, and the CQI of the first channel #5 is 6.

[0069] It can be understood that the channels and beams described in the embodiments of the present application can be in a one-to-one correspondence, and different channels correspond to different beams. For details, please refer to the relevant introduction of the "beam" above.

[0070] It can also be understood that if the channel quality of the first channel corresponding to a certain receiving beam is not good, it means that the channel quality in the spatial direction pointed by the receiving beam is relatively poor, and there may be signal interference.

[0071] S202: If the channel quality of the first channel is less than the first channel quality threshold, the IoT device increases the detection power of the infrared detection.

[0072] Among them, if the channel qualities of K first channels among the M first channels are less than the first channel quality threshold, the IoT device increases the detection power of infrared detection according to the angle between the K receiving beams corresponding to the K first channels among the M receiving beams and the infrared detection direction of the IoT device, where K is an integer ranging from 1 to M. For example, the IoT device can determine the first target receiving beam with the largest angle with the infrared detection direction of the IoT device among the K receiving beams; the IoT device increases the detection power of infrared detection according to the angle between the first target receiving beam and the infrared detection direction of the IoT device. For example, the IoT device can adjust the amplification factor of its own amplification circuit to enhance both the infrared signal and the interference, so that the interference can be better filtered out later, and the infrared signal is also large enough. Among them, the larger the angle between the first target receiving beam and the infrared detection direction of the IoT device, the greater the increase in the detection power of infrared detection.

[0073] That is to say, if the signal interference source is in front of the infrared detection party, its propagation direction is the same as the infrared radiation direction, and it is not easy to cause interference. However, if the signal interference source is in front of the infrared detection party, its scattering and diffraction are more likely to cause electromagnetic radiation interference to the infrared detection circuit. Therefore, the Internet of Things device needs to determine the size of the interference based on the angle between the receiving beam and the infrared detection direction of the Internet of Things device. Of course, the above methods are some exemplary implementation methods of the embodiments of the present application. For example, the Internet of Things device can also determine the beam direction. As long as the channel quality of the first channel is less than the first channel quality threshold, it is considered that interference exists.

[0074] For example, still Figure 3 As shown, the first channel quality threshold is CQI=10, and the IoT device determines that the CQI of the first channel #2 is 5, which is less than the first channel quality threshold, and the CQI of the first channel #5 is 6, which is less than the first channel quality threshold. Since the angle between the receiving beam #2 corresponding to the first channel #2 and the infrared detection direction is larger, the IoT device increases the detection power of the infrared detection according to the CQI of the first channel #2.

[0075] In summary, since the channel quality of different receiving beams can reflect the interference received by the wireless signal in space, the IoT device can detect whether there is electromagnetic interference in space by measuring the channel quality through different receiving beams. Therefore, it can increase the detection power in the presence of electromagnetic interference to counteract the interference.

[0076] Optionally, if the channel quality of the first channel is greater than or equal to a first channel quality threshold, the method further includes:

[0077] Step 1: The IoT device determines the channel quality of the second channel through the beam of the second antenna panel, where the second channel is a channel in the direction of the beam pointing to the second antenna panel.

[0078] When there are reflectors, such as buildings and trees, in the opposite direction of the infrared detection direction of the IoT device, the electromagnetic interference propagating in the opposite direction of the infrared detection direction (referred to as forward propagation) may be reflected by the reflector and offset with the electromagnetic interference propagating forward. At this time, the channel quality of the first channel is still good. To avoid this situation, the IoT device can use the second antenna panel for detection.

[0079] For example, the IoT device receives a second downlink signal from the network device through a receiving beam of the second antenna panel; the IoT device determines the channel quality of the second channel based on the second downlink signal.

[0080] Furthermore, the receiving beam of the second antenna panel includes N receiving beams pointing to different directions, where N is greater than 1. In this case, the IoT device can receive the second downlink signal from the network device through the N receiving beams of the second antenna panel, respectively, for a total of N second downlink signals, and the N receiving beams correspond one-to-one to the N downlink signals. In this way, the IoT device determines the channel quality of each of the N second channels, such as CQI, based on the N second downlink signals, and the N downlink signals correspond one-to-one to the N first channels.

[0081] For example, Figure 4 As shown, the N receiving beams include receiving beam #A, receiving beam #B, receiving beam #C, receiving beam #D, and receiving beam #E. The IoT device first uses receiving beam #A to receive the second downlink signal in the order of the beam numbers from small to large to measure the channel quality of the second channel #1, and then uses receiving beam #B to receive the second downlink signal to measure the channel quality of the second channel #2, and so on, until receiving beam #E is used to receive the second downlink signal to measure the channel quality of the second channel #5. In this case, the CQI of the second channel #1 is 5, the CQI of the second channel #2 is 25, the CQI of the second channel #3 is 6, the CQI of the second channel #4 is 16, and the CQI of the second channel #5 is 16.

[0082] Step 2: If the channel quality of the second channel is greater than the second channel quality threshold, the IoT device increases the detection power of the infrared detection, and the second channel quality threshold is less than the first channel quality threshold.

[0083] If the channel qualities of J second channels among the N second channels are greater than the second channel quality threshold, the Internet of Things device increases the detection power of infrared detection according to the angle between J receiving beams among the N receiving beams corresponding to the J first channels and the infrared detection direction of the Internet of Things device, where K is an integer from 1 to M; wherein the Internet of Things device increases the detection power of infrared detection according to the angle between J receiving beams among the N receiving beams corresponding to the J first channels and the infrared detection direction of the Internet of Things device, including: the Internet of Things device determines, from the J receiving beams, a second target receiving beam having the smallest angle with the infrared detection direction of the Internet of Things device; the Internet of Things device increases the detection power of infrared detection according to the angle between the second target receiving beam and the infrared detection direction of the Internet of Things device, and the smaller the angle between the second target receiving beam and the infrared detection direction of the Internet of Things device, the greater the increase in the detection power of infrared detection.

[0084] That is to say, if the signal interference source is placed directly behind the infrared detection, its propagation direction is opposite to the infrared radiation direction, and it can directly cause electromagnetic radiation interference to the infrared detection circuit. Therefore, the IoT device needs to determine the size of the interference based on the angle between the receiving beam and the infrared detection direction of the IoT device. Of course, the above methods are some exemplary implementation methods of the embodiments of the present application. For example, the IoT device can also determine the beam direction. As long as the channel quality of the first channel is less than the first channel quality threshold, it is considered that interference exists.

[0085] For example, still Figure 4 As shown, the second channel quality threshold is CQI=8, the CQI of the second channel #1 is 5, which is less than the second channel quality threshold, and the CQI of the second channel #3 is 6, which is less than the second channel quality threshold. Since the angle between the receiving beam #C corresponding to the second channel #3 and the infrared detection direction is smaller, the IoT device increases the detection power of the infrared detection according to the CQI of the second channel #3.
