Taking the communication system 100 shown in FIG. 1 as an example, the communication device may include a network device 110 and a terminal device 120 with a communication function, and the network device 110 and the terminal device 120 may be the specific devices described above, which will not be repeated here.

It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and/or" in this article is just an association relationship that describes an associated object, which means that there can be three kinds of relationships, for example, A and/or B, which can mean: A exists alone, A and B exist at the same time, exist alone B these three cases. In addition, the character "/" in this article generally indicates that the related objects before and after are in an "or" relationship.

For wireless terminals used for cellular communications, the signals generated or transmitted inside the terminal equipment will cause self-interference to the simultaneously received downlink signals. Among them, the internally generated or transmitted signal can be called a self-interference signal.

According to the source of the self-interference signal, the self-interference signal can be divided into the following three categories.

The first type of self-interference signal may be a harmonic or intermodulation interference signal generated by one or several uplink transmission signals of the cellular system.

The second type of self-interference signal comes from the interference between different wireless communication modules inside the mobile phone. Among them, the interference between wireless fidelity (WiFi) signal and cellular signal is more obvious.

The third type of self-interference signal mainly originates from the electromagnetic waves generated by some active electronic devices inside the terminal equipment. This type of self-interference signal mainly originates from the electromagnetic wave generated by the terminal's display screen, the terminal's memory reading operation, the terminal's camera and electric motor and other devices. The frequency of this type of electromagnetic wave is roughly in the range of tens of MHz to hundreds of MHz. When its harmonic falls on the cellular band, or its harmonic intermodulates with the transmission of the cellular band, it will interfere with the reception of the cellular band.

The third type of self-interference signal differs from the first two types of interference signals in that such self-interference signals originate from whether certain components are used. For example, for the self-interference signal from the display screen, if the display screen is not turned on, the self-interference signal does not exist. The self-interference signal generated by the electric motor only exists when it is turned on. Another characteristic of this type of self-interfering signal is that the interference frequency is relatively fixed, and its bandwidth is generally relatively narrow.

The following provides a method of how to handle the third self-interference signal. In this method, the self-interference generated by the operation of the internal electronic device can be predicted to the network device, so that the terminal device can reasonably make the terminal device based on the prediction of the terminal device. Scheduling to avoid interference with downlink reception, which can improve communication performance.

In addition, the interference bandwidth of self-interference generated by internal electronic devices is relatively narrow. When the network equipment learns that self-interference is generated, it can easily avoid the interference bandwidth of self-interference.

FIG. 2 is a schematic flowchart of a wireless communication method 200 according to an embodiment of the present application. The method 200 includes at least part of the following content.

In 210, the terminal device sends first information to the network device, and the first information is used to predict to the network device that self-interference will occur inside the terminal device, where the self-interference is caused by the terminal device. Of electronic devices.

Correspondingly, in the method 300 shown in FIG. 3, in 310, the network device receives first information sent by the terminal device, and the first information is used to predict to the network device that self-interference will occur inside the terminal device , Where the self-interference is caused by the operation of electronic devices inside the terminal equipment.

Specifically, for self-interference caused by the operation of electronic devices inside the terminal equipment, such self-interference will exist when the electronic devices are operated. Whether these electronic devices start to operate depends on the user behavior of the terminal equipment and the working behavior of the terminal equipment itself. For the network side, these behaviors are relatively unpredictable, but for the terminal equipment, the terminal equipment is predictable or Learned earlier than the actual time of self-interference.

For example, for self-interference caused by the screen, the terminal device can predict the occurrence of self-interference in advance through user behavior. For example, when the user uses the program of timed reminder or alarm clock, the terminal device can know in advance when the screen will turn on (because the reminder and alarm clock function of the terminal device will be accompanied by the function of screen activation).

As another example, when the user activates the screen by using a button or a touch screen, there will be a short interval from the user's action to the actual screen activation, such as 0.1s. This short interval is actually known by the terminal device.

As another example, interference from the camera, from the user opening the camera interface of the application to the actual opening of the camera, there will generally be a short delay, and this delay is controlled by the specific software implementation of the terminal.

Although these delays are very short, such as the above-mentioned delay of the screen or camera being activated, such as 0.1s, for cellular communication systems, if the system can get forecasts dozens of ms in advance, network equipment can already avoid The downlink frequency is scheduled for the interfered frequency. Therefore, if the terminal can predict the upcoming self-interference to the network equipment in advance, it will be very beneficial for the terminal and the system to be protected from interference.

Therefore, in the embodiment of the present application, the terminal device may send the first information to the network device when it is determined that the terminal device will generate self-interference, so as to preset the network device that the terminal device will generate self-interference.

It should be understood that in the embodiments of the present application, the self-interference generated by the operation of electronic devices inside the terminal equipment may be understood as the self-interference signals generated by the operation of the electronic devices. These self-interference signals will interfere with the downlink signals received by the terminal equipment at the same time. When self-interference occurs during operation, there may or may not be received downlink signals.

Optionally, in the embodiment of the present application, the electronic device that generates the self-interference includes at least one of the following:

The display screen of the terminal device;

A memory read-write device of the terminal device;

The camera of the terminal device;

The electric motor of the terminal device.

Of course, in the embodiments of the present application, the electronic devices that generate self-interference may also include other electronic devices, which are not specifically limited in the embodiments of the present application.

Optionally, in the embodiment of the present application, the first information is also used to indicate at least one of the following (1) to (6).

(1) The duration of the self-interference

Specifically, for some electronic devices, the terminal device can predict the running time of the electronic device, that is, the terminal device can predict the duration of self-interference, and thus the terminal device can report the duration of self-interference to the network device Then, the network device may perform reasonable scheduling on the terminal device based on the duration, for example, it may avoid downlink scheduling on the terminal device within the duration.

Among them, the terminal device can predict the running time of some electronic devices, while some electronic devices, the terminal device cannot predict the running time.

For example, for self-interference caused by memory read and write, since the memory read and write is controlled by the operating system, the terminal device is relatively easy to obtain the duration of memory read and write, so that the terminal device can predict the duration of its self-interference to the network device . However, for the running time of the screen or the camera, which cannot be predicted by the terminal device, the duration of the self-interference may not be included in the first information at this time.

(2) The interval between the generation time of the self-interference and the transmission time of the first information

Specifically, since the terminal device predicts to the network device that the terminal device will generate self-interference, and when the specific time occurs, it can be further notified to the network device. In this case, the network device can further accurately know the self-interference. Occurrence time, so as to achieve more reasonable scheduling of terminal equipment. The notification method of when the self-interference occurs may be implemented by notifying the interval between the generation time of the self-interference and the transmission time of the first information, that is, how long after the specific first information is transmitted There will be self-interference.

Of course, in the embodiment of the present application, the terminal device may send the first information to the network device at a specific time before the occurrence of self-interference, for example, sending the first information to the network device 50 ms before the occurrence of self-interference, then The network device may learn that self-interference will occur 50 ms after receiving the first information.

(3) The type of electronic device that produces the self-interference

Specifically, due to different types of electronic devices, the frequency, bandwidth, and/or intensity of self-interference may be different, and the terminal device may report the type of the electronic device that generates the self-interference to the network device, so that the network device may be based on the electronic device The type of self-interference determines the interference frequency, interference bandwidth and interference intensity.

Among them, the interference frequency, interference type and interference intensity generated by various electronic devices may be preset on the network side, or may be reported by the terminal device to the network side. Specifically, the terminal device may first report it to the network device Types of internal electronic devices that can generate self-interference, as well as the interference frequency, interference bandwidth, and/or interference intensity of self-interference generated by various types of electronic devices. Therefore, when the terminal device determines that self-interference is about to occur, it can report the type of the electronic device to the network side when predicting the self-interference to the network side, so that the network device can judge the self-interference according to the type of the electronic device. Interference frequency, interference bandwidth and interference intensity, etc.

(4) The interference frequency of the self-interference

The self-interference signal generated by the operation of the electronic device can generate the following three types of interference to the downlink received signal: intermodulation (IM) interference, harmonic interference, and harmonic intermodulation interference.

For intermodulation interference, the frequency of a certain order intermodulation signal of self-interference signal 1 (which can be generated by the operation of the electronic device) and self-interference signal 2 (which can be generated by the operation of the electronic device or an upstream transmission signal) The frequency of a downlink signal of a carrier F1 overlaps or partially overlaps. Then self-interference signal 1 and self-interference signal 2 constitute intermodulation interference to the downlink signal of carrier 1.

For example, memory read and write will generate a signal of about 1G, and a 3.5G cellular transmission signal will generate a second-order intermodulation signal, which will interfere with the 2.6G cellular reception signal. Then when the memory read and write self-interference signal is generated, the terminal The interference frequency that the device can report to the network device is 1G.

For harmonic interference, the multiple of the frequency of the self-interfering signal 1 (which can be generated by the operation of the electronic device) overlaps or partially overlaps with the frequency of the downlink signal of a carrier 1, then the downlink of the self-interfering signal 1 to the carrier 1 The signal constitutes harmonic interference.

For example, the display screen will generate a signal with a frequency of about 450M. The second harmonic 900M and the fourth harmonic 1.8G will interfere with the reception of the cellular frequency band. Then when the screen self-interference occurs, the terminal can report to the network equipment. The interference frequencies are 900M and 1.8G.

For harmonic intermodulation interference, the frequency multiplier of a carrier 1 overlaps or partially overlaps with the frequency of the self-interference signal 1 (and its adjacent frequencies), then the carrier self-interference signal 1 to the downlink signal of carrier 1 constitutes a harmonic Intermodulation interference. At this time, the terminal device may report the frequency of the self-interference signal to the network side.

(5) The interference bandwidth of the self-interference

Similar to the interference frequency above, the interference bandwidth here can be the bandwidth of the self-interference signal itself or the harmonic bandwidth of the self-interference signal.

The terminal device reports the interference bandwidth of self-interference to the network device, so that the network device can avoid scheduling the terminal device within the bandwidth range.

(6) The interference intensity of the self-interference

The terminal device can report the interference intensity of self-interference to the network device, so that the network device can determine whether to avoid the self-interference and perform downlink scheduling on the terminal device based on the interference intensity.

The terminal device may carry at least one of the above (1)-(6) in the first information. It should be understood that, in the embodiment of the present application, the first information may include various types of information (for example, information that self-interference will occur , Duration, interference strength, etc.), the various information can be carried in different signaling.

Optionally, in the embodiment of the present application, the terminal device may determine whether to make a forecast to the network device and/or determine the time to send the first information when it knows that self-interference operated by the electronic device will occur.

For example, some self-interference can be predicted by the terminal, but the time that the terminal device can predict in advance is short. For example, the terminal device's self-interference caused by the reading and writing of the memory, the operating system of the terminal device can be delayed for a short time (such as 1 ~ 5ms) to execute (longer delay time will cause a decrease in user experience, which is not a relatively Good choice), this delay time is the time that the terminal equipment may predict in advance. However, for network equipment, the prediction of self-interference a few ms in advance may not be very useful, so the terminal equipment may not predict to the network equipment that the self-interference will occur.

As another example, for the operation of awakening the screen or camera triggered by the terminal application timer, the terminal device can know when such interference occurs a long time in advance. But for the network equipment, it is meaningless to know that some interference will occur too early in advance, and the terminal equipment can postpone the prediction of the self-interference to the network equipment.

Among them, there may be a predicted maximum threshold and/or a minimum threshold, that is, if the time between the current time and self-interference is less than the minimum threshold, the self-interference forecast will no longer be performed, if the current time and If the time interval when the self-interference will occur is greater than the maximum threshold, the prediction can be postponed to the maximum threshold.

The above-mentioned maximum threshold value and/or minimum threshold value may be preset on the terminal device, or may be configured by the network device.

Specifically, the network device may send second information to the terminal device, where the second information indicates a maximum threshold value and/or a minimum threshold value of the interval, where the interval is the generation time of the self-interference and the The interval between the transmission times of the first information. The terminal device receives the second information sent by the network device; based on the maximum threshold value and/or the minimum threshold value, the terminal device optionally determines the sending time of the first information, and/or To determine the type of electronic device corresponding to the self-interference that needs to be predicted.

Optionally, in the embodiments of the present application, different service types correspond to different maximum thresholds and/or minimum thresholds.

The service types in the embodiments of the present application may include a highly reliable and low-latency (Ultra-Reliable Low Latency Communications (URLLC)) service and an enhanced mobile broadband (Enhance Mobile Broadband (eMBB)) service. In addition to the eMBB and URLLC services mentioned above, there may actually be terminals that support more business types, such as terminals that support Internet of Vehicles (Vehicle to to Anything, V 2X), Industrial Internet of Things (Industrial Internet of Things, IIoT) services, At this time, the service types of the embodiments of the present application may include V2X services and IIoT services.

Optionally, in the embodiments of the present application, different service types may correspond to different scheduling periods and/or reliability requirements.

Optionally, in the embodiment of the present application, the network device may notify the terminal device in the form of general signaling (eg, broadcast signaling) or dedicated signaling (radio resource control (Radio Resource Control, RRC) signaling) when When the terminal device cannot predict a certain self-interference at least Xms in advance, there is no need to predict the self-interference. When general signaling is used, the Xms may be the same for all terminal devices, and when dedicated signaling is used, the Xms of different terminal devices may be different.

For example, for terminal devices using eMBB services, X = 20 ms, and for terminal devices using URLLC services, X = 5 ms. This is because the network equipment has different scheduling periods and reliability requirements for different services. For eMBB, only 5ms forecast in advance does not help the network equipment avoid interference (the scheduling of network equipment may be 10 to 20ms before the actual downlink transmission occurs). Made). But for the URLLC service, the delay, especially reliability, is very high. Predicting interference 5ms in advance can already help network equipment avoid interference.

The network device may also notify the terminal device in the form of general signaling (for example, broadcast signaling) or dedicated signaling (RRC signaling). The terminal device does not need to predict a certain self-interference to the network device in advance by more than Yms. For example: Y=200ms. That is to say, only when the interference is about to occur within 50ms, the terminal device needs to report to the network side.

Optionally, in the embodiment of the present application, the above-mentioned first information may be carried in physical layer signaling (for example, in a physical uplink control channel (Physical Uplink Control Channel, PUCCH) or in a physical uplink shared channel (Physical Uplink Shared Channel) , PUSCH) carries uplink control information (Uplink Control Information, UCI)), or Media Access Control (MAC)/RRC signaling may also be used.

Optionally, in the embodiment of the present application, the resource carrying the first information may be determined according to the type of the electronic device that generates the self-interference.

The network device may send the fifth information to the terminal device to indicate the correspondence between the type of the electronic device that generates the self-interference and the resource that carries the first information, and then the terminal device may determine to bear the first according to the fifth information Information resources.

Specifically, if reporting through PUCCH, the network device may pre-configure different PUCCH resources for different types of electronic devices, so that the network device can determine the type of electronic device that has self-interference according to the PUCCH resource carrying the first information. The specific content carried by the PUCCH may be at least one of (1)-(6) above.

Optionally, in the embodiment of the present application, the terminal device may select the method for predicting the self-interference according to the interval between the time when the self-interference is learned (that is, the time when the first information can be sent) and the time when the self-interference time occurs. Signalling.

For example, for self-interference occurring within 50 ms, physical layer signaling is used for reporting; for self-interference occurring within 50 ms to 200 ms, MAC or RRC signaling may be used for reporting. This is due to the use of physical layer signaling for self-interference that occurs within a short period of time, which can be reported to the network as soon as possible, which helps network equipment to use reasonable scheduling to avoid interference; and for interference that occurs over a relatively long time, use MAC /RRC signaling helps save physical layer resources.

The correspondence between the above interval and the signaling used for prediction can be preset on the terminal device, and based on this correspondence, the terminal device can determine which type of signaling is used for self-interference prediction.

Alternatively, the network device may send third information to the terminal device, where the third information indicates the correspondence between the interval and the signaling type, where the interval is the generation time of the self-interference and the transmission time of the first information After receiving the third information, the terminal device may determine the signaling type of the signaling carrying the first information based on the third information.

Optionally, in the embodiment of the present application, the terminal device may send fourth information to the network device, where the fourth information is used to indicate that the terminal device can predict the type of the corresponding self-interfering electronic device.

Specifically, the terminal device can first send to the network device which self-interference generated by the electronic device can be predicted, wherein, at the same time, the terminal device can send to the network device the interference frequency, interference bandwidth, and interference corresponding to the electronic device that can predict the corresponding self-interference At least one of the time interval of the intensity, the first information and the self-interference to occur, and the duration of the interference. Then, in the prediction of self-interference, only the type of electronic device can be reported, so that the network device can determine the interference frequency, interference bandwidth, interference intensity, first information and the time interval of self-interference that will occur according to the type of electronic device And at least one of interference duration.

Specifically, among the various self-interferences caused by the internal electronic devices of the terminal mentioned above, some of the terminal equipment may be predicted in advance, such as interference caused by the screen and the camera, but some may be that the terminal equipment cannot be predicted in advance Yes, even if it can be predicted in advance, but the advance time is short, the terminal device can judge whether the length of the advance prediction is greater than or equal to the minimum threshold value, and if greater than or equal to, it can be determined that the forecast can be made.

Then, the terminal device may first listen to the signaling of the network device about the minimum threshold value, and then report to the network device which types of self-interference the terminal can predict based on the setting of the network device about the minimum threshold value.

Optionally, in the embodiments of the present application, under different service types, the types of corresponding self-interfering electronic devices can be predicted to be different.

For example, in the above example, X=20ms for the eMBB service, and X=5ms for the URLLC service. The self-interference caused by a terminal device to the screen and camera can be predicted at least 20ms in advance, and the interference caused by memory read and write can only be predicted in advance by 5ms. Then this terminal will report to the network equipment that it can predict the interference caused by the screen and camera to the eMBB service, and that the URLLC service can predict the interference caused by the screen, camera and memory read and write.

The fourth information in the embodiment of the present application may be carried in RRC or MAC signaling.

Optionally, in the embodiment of the present application, even if the terminal device has sent the first information to predict to the network device that the electronic device inside the terminal device will generate self-interference, the terminal device still generates the self-interference when the self-interference occurs. The sixth information may be sent to the network device, where the sixth information is used to indicate that the terminal device currently has the self-interference. Then, the network device may schedule the terminal device according to the sixth information.

Specifically, even if the terminal device predicts the occurrence of self-interference to the network device, but the interference may not occur, when the actual occurrence occurs, the network device may be indicated that there is currently self-interference, which may enable the network device to grasp the information of self-interference More clearly. Of course, the terminal device may also notify the network device that the predicted self-interference has not occurred when the predicted self-interference has not occurred, and may not need to report to the network device when it occurs.

Optionally, when the self-interference stops, the terminal device may send information to the network device to indicate that the self-interference stops, so that the network device does not need to avoid downlink scheduling on the interference frequency band.

For example, when an electronic device that generates self-interference, such as a camera or a display screen, stops operating, the self-interference generated by the electronic device also disappears. At this time, the terminal device may send information indicating that the self-interference stops to the network device.

It should be understood that some occurrences of self-interference are unpredictable or have a shorter time in advance, so the terminal device may not send the first information to the network device, and may send the sixth information when it is determined that self-interference occurs.

In this case, even if the occurrence of self-interference is not predicted in advance, but the duration of the self-interference is predictable by the terminal device, the terminal device may indicate the duration of the self-interference in the sixth information.

Specifically, the terminal device may report the time when the interference occurs to the network when reporting the occurrence of interference, for example, inserting an information bit in the PUCCH or UCI indicating that there is currently self-interference to indicate the duration of self-interference, or A corresponding field is added to the RRC/MAC signaling indicating that there is currently self-interference to indicate the duration of self-interference.

Alternatively, the duration of self-interference may be in different signaling than the information indicating that there is currently self-interference. For example, you can first predict the duration of one or some kinds of self-interference to the network equipment, and notify the network equipment when self-interference occurs when self-interference occurs.

When self-interference occurs, the terminal device needs to report the occurrence of self-interference to the network device, and the following methods may be adopted.

Once self-interference occurs, it will interfere with the downlink received signal, so the sooner the network device knows that the self-interference has been generated, the better, so that the network device can avoid self-interference by using a scheduling method. Similarly, when self-interference disappears, the faster the network device knows, the better, so that the network device can schedule on the previously interfered resource. Therefore, the reporting of interference can use the signaling of the physical layer (L1), specifically PUCCH or UCI (when there is PUSCH).

For PUCCH, the network device can configure the terminal with a PUCCH resource specifically used to report interference. When interference occurs/disappears, the terminal can send a report to the network on the configured resource using the appropriate PUCCH format, including the above Information: Occurrence/disappearance of interference, frequency of interference and type of interference, etc.

For UCI in PUSCH, the terminal device may multiplex the data channel to send the first information.

Of course, in addition to physical layer signaling, MAC or RRC signaling can also be used to report upwards. This has the advantage of saving physical layer resources. For example, the network device can configure whether the terminal uses physical layer signaling or MAC or RRC signaling to report interference according to the current downlink scheduling. If there is no downlink scheduling currently, the network device can configure the terminal device to use MAC or RRC for the above reporting; if there is currently downlink scheduling, the network device can configure the terminal device to use the physical layer signaling for the above reporting.

Optionally, the method used by the terminal to report self-interference can be achieved through the specific configuration of the network device. Specifically, the network device may pre-configure the signaling type used by the terminal device to report self-interference, and then send configuration information to the terminal device, where the configuration information may include the signaling type used by the terminal device to report self-interference.

Among them, the configuration information may be carried in downlink control information (Downlink Control Information, DCI), RRC or MAC signaling.

Alternatively, the terminal device may select the signaling used to send the first information according to the duration of self-interference and/or the interference intensity of self-interference.

For example, if the duration of self-interference is greater than or equal to the duration threshold, the terminal device may use physical layer signaling to send the first information; if the duration of the self-interference is smaller than the duration threshold, the terminal device may use RRC or MAC signaling to send The first message.

For another example, if the interference intensity of self-interference is greater than or equal to the interference intensity threshold, the terminal device may use physical layer signaling to send the first information; if the duration of the self-interference is less than the interference intensity threshold, the terminal device may use RRC or MAC signaling Send the first message.

It should be understood that any upstream message sent by the terminal device reports self-interference to the network device.

Since these interferences are caused by the internal components of the terminal starting to operate, such as the display screen and the electric motor, or the camera, once the interference is generated, the duration may be relatively long (at least in seconds), so when the interference occurs It may not have established a formal wireless link (RRC connection) with the network equipment. At this time, when such interference occurs before the RRC connection is established, and such interference continues during the establishment of the RRC connection, the terminal needs to report to the network device as soon as the RRC connection is established, or as soon as possible after the establishment.

For example, the terminal device may report the presence of interference to the network through message 1 (Msg1) or message 3 (Msg3) during the random access process. In this way, the terminal device can report the current self-interference to the network device at the fastest speed.

For another example, after the RRC connection is established, the terminal device may report to the network through the above physical layer/MAC/RRC signaling.

For another example, the terminal device may report to the network device through the connection reestablishment message.

The terminal device can indicate to the network device which electronic devices' duration of self-interference is predictable.

For example, for the interference caused by memory read and write, since the memory read and write is controlled by the operating system, it is easier for the terminal to obtain the duration of memory read and write. In this way, the terminal can report to the network equipment which duration of the self-interference of the electronic device can be predicted by the terminal, and which self-interference of the electronic device cannot be predicted by the terminal.

And, as mentioned above, it is possible to indicate to the network equipment which occurrences of self-interference of electronic devices can be predicted. The two kinds of indications (indicating the duration of self-interference of electronic devices can be predicted and the indication of the occurrence of self-interference of electronic devices can be predicted) can be carried by the same signaling or by different signaling Bearer.

Alternatively, the terminal device may send signaling separately for different types of electronic devices. For example, the terminal device can send a signaling to the network device indicating that the occurrence of self-interference from memory read and write is unpredictable, but its duration can be predicted; and send another signaling to indicate the self-interference from the screen The occurrence of interference can be predicted, but the duration cannot be predicted. Of course, the combination of these two signaling functions is realized by one function.
