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

Among them, the first type of self-interfering signal may be harmonic or intermodulation interference generated by one or several transmitted signals of the communication system. For example, it may be harmonic or intermodulation interference generated by one or several transmitted signals of a cellular communication system.

The second type of self-interference signal comes from the interference between different wireless communication modules inside the terminal device, for example, the interference between WiFi signals and cellular signals.

The third type of self-interference signal mainly originates from the electromagnetic waves generated by some active electronic devices inside the terminal equipment. For example, electromagnetic waves generated by electronic devices such as the display screen of the terminal device, the memory reading device of the terminal device, the camera and the electric motor of the terminal device. The frequency range of the electromagnetic wave may be tens of MHz to hundreds of MHz. When its harmonic falls on the cellular frequency band or its harmonic intermodulates with the transmitted signal of the cellular frequency band, the electromagnetic wave will produce the reception of the cellular frequency band interference.

Among them, the third type of self-interference mainly has two characteristics: (1) The third type of self-interference comes from whether certain devices inside the terminal equipment are used. For example, for self-interference from the display screen, if the display screen is not turned on, there is no self-interference. As another example, the self-interference generated by the electric motor only exists when the electric motor is running. (2) The frequency of the third type of self-interference is relatively fixed, and the bandwidth is generally narrow.

For the third type of interference, the third type of interference only exists when certain devices inside the terminal equipment are running. However, whether these devices start running depends on the user behavior of the terminal device and the working behavior of the terminal device itself, and these behaviors are not visible to the network side.

In view of this, an embodiment of the present application proposes a method of self-interference reporting. In this method, the terminal device can report to the network device the self-interference generated by the operation of the electronic device inside the terminal device, so that the network device can be based on the terminal The reporting of the device performs reasonable scheduling on the terminal device to avoid interference with downlink reception, thereby improving communication performance.

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

FIG. 2 is a schematic flowchart of a communication method 200 according to an embodiment of the present application. The method 200 may be executed by a terminal device, and may include at least part of the following content.

In 210, the terminal device sends first information to the network device, where the first information is used to indicate that the terminal device currently has self-interference, where the self-interference is generated by the operation of electronic devices inside the terminal device.

FIG. 3 is a schematic flowchart of a communication method 300 according to an embodiment of the present application. The method 300 may be performed by a network device, and may include at least part of the following content.

In 310, the network device receives first information sent by the terminal device, where the first information is used to indicate that the terminal device currently has self-interference, where the self-interference is generated by the operation of electronic devices inside the terminal device.

The communication method of the embodiment of the present application will be further described below with reference to FIGS. 2 and 3. It should be understood that the embodiments are mostly described from the perspective of the terminal device. It can be understood that the terminal device receives from the network device, which means that the network device has sent.

In the embodiments of the present application, the self-interference generated by the operation of the electronic devices in 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, and the self-interference caused by the operation of the electronic devices At this time, there may be a received downlink signal, or there may be no received downlink signal.

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

The display screen of the terminal equipment;

Memory reading and writing device of terminal equipment;

The camera of the terminal device;

Electric motor for terminal equipment.

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 may also be used to indicate at least one of the following (1)-(5)

(1) Duration of 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, and some electronic devices, the terminal device can not predict the running time.

For example, for self-interference caused by memory read and write, since memory read and write is controlled by the operating system, it is easier for the terminal device to obtain the duration of memory read and write, so that the terminal device can report 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.

It should be understood that for the third type of interference, the duration of self-interference may be in the order of seconds.

(2) Types of electronic devices that generate 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, such as the self-interference generated by the display screen. It is also the self-interference caused by the memory reading device or the electric motor, so that the network equipment can determine the interference frequency, interference bandwidth, and interference intensity of the self-interference according to the type of the electronic device.

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 reports the existence of self-interference to the network side, it can report the type of the electronic device to the network side, so that the network device can determine the interference frequency, interference bandwidth, and interference intensity of self-interference according to the type of the electronic device .

(3) Interference frequency of self-interference

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

(4) Self-interference interference bandwidth

Similar to the interference frequency above, the interference bandwidth here may 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.

(5) Self-interference interference intensity

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.

For example, if the interference intensity of self-interference is greater than or equal to the interference intensity threshold, the network device may determine to avoid self-interference; if the interference intensity of self-interference is less than the interference intensity threshold, the network device may determine not to avoid the self-interference.

The terminal device may carry at least one of the above (1)-(5) 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 currently exists) , The duration of self-interference, the interference intensity of self-interference, etc.), the various types of information can be carried in the same signaling or in different signaling.

It should be noted that the self-interference generated by different electronic devices inside the terminal device may vary in frequency, bandwidth, intensity, or duration. For example, the self-interference frequency of the display screen may be 900M and 1.8G, and the self-interference frequency of the memory reading device may be 1G.

Optionally, in the embodiment of the present application, the terminal device sends the first information to the network device. As an example, the terminal device may send the first information to the network device when determining that self-interference occurs.

For example, when certain electronic devices inside the terminal device, such as an electric motor, start to work, the terminal device can determine that the electromagnetic waves generated by the electronic device will cause self-interference to the downstream reception signal of the terminal device. The network device sends the first information.

As another example, if the terminal device has self-interference in the process of establishing a connection with the network device, during the process of establishing the connection between the terminal device and the network device, the terminal device may send the first information to the network device.

Alternatively, the terminal device may send the first information to the network device as soon as possible after establishing a connection with the network device.

Among them, the self-interference already exists in the process of establishing connection between the terminal device and the network device, which can be understood as: when the self-interference occurs, the terminal device has not established a formal wireless link connection with the network device, and the terminal device and the network device are established During the connection, self-interference continues; or, during the connection between the terminal device and the network device, self-interference occurs.

Optionally, the terminal device may carry the first information in any uplink message sent.

Exemplarily, when the terminal device sends the first information in the process of establishing a connection with the network device, the terminal device may send the first message to the network device through message 1 (Msg1) or message 3 (Msg3). That is, the terminal device may send the first message to the network device through Msg1 or 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, the terminal device may send the first information to the network device through a connection reestablishment message.

For another example, after establishing a connection with the network device, the terminal device may send the first message to the network device through physical layer signaling, RRC signaling, or MAC signaling.

Regarding the signaling type used by the terminal device to send the first information, optionally, the network device may pre-configure the signaling type used by the terminal device to send the first information, and then send the configuration information to the terminal device, where the configuration information may include the terminal The signaling type used by the device to send the first information. After receiving the configuration information, the terminal device may determine the signaling type used to send the first information.

Among them, the configuration information can be carried in downlink control information (Downlink Control Information, DCI), radio resource control (Radio Resource Control, RRC) or signaling media access control (Media Access Control, MAC) signaling.

In the process of the network device determining the signaling type used by the terminal device to send the first information, as an example, the network device may determine the signaling type used by the terminal device to send the first information according to whether there is downlink scheduling at the current time.

If the terminal device has downlink scheduling at the current moment, the network device may determine that the signaling type carrying the first information is physical layer signaling.

It should be understood that once self-interference occurs, it will cause interference to the downlink received signal, so the sooner the network device knows that the self-interference has been generated, the better the network device can use the scheduling method to avoid the self-interference. Therefore, the terminal device may use physical layer signaling to send the first information to the network device with the best effect.

Specifically, the first information may be carried in the physical uplink control channel (Physical Uplink Control Channel, PUCCH) or the physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) uplink control information (Uplink Control Information (UCI)) (when When PUSCH is available).

For PUCCH, the network device may configure the terminal device with a PUCCH resource specifically used to send the first information. When the terminal device sends the first information to the network device, it may send the first information on the configured resource by using the determined PUCCH format.

Among them, the content carried by the first information is different, and the PUCCH format may be different.

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

If the terminal device does not have downlink scheduling at the current moment, the terminal device may use RRC signaling/MAC signaling to send the first information to the network device. In this way, physical layer resources can be saved.

Optionally, 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.

Optionally, in the embodiment of the present application, when reporting the presence of self-interference to the network device, the terminal device may simultaneously report to the network device the type of electronic device that generates self-interference, the interference frequency of self-interference, the interference bandwidth of self-interference, and the self-interference bandwidth. At least one of the interference intensity of interference and the duration of self-interference.

For example, inserting an information bit in the PUCCH or UCI used to indicate the presence of self-interference indicates the interference frequency of self-interference, or adding a corresponding field to the RRC or MAC signaling indicating the presence of self-interference to indicate the interference frequency of self-interference.

For the third type of interference, the network side does not know when the self-interference disappears. Therefore, the method in the embodiment of the present application may further include: the terminal device sends second information to the network device, where the second information is used to indicate self-interference disappear. After the network device receives the second information, it is determined that the self-interference disappears, so that scheduling can be performed on the previously interfered resource.

Optionally, the terminal device may send the second information to the network device when it is determined that the self-interference disappears.

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 second information to the network device.

Optionally, in the embodiment of the present application, the second information may be carried in physical layer signaling (for example, UCI in PUCCH or PUSCH), and of course, the second information may also be carried in RRC signaling/MAC signaling .

It should be understood that when self-interference disappears, the sooner the network device knows the better, so that the network device can schedule on the previously interfered resource, in this case, the second information can be carried in physical layer signaling; when When the second information is carried in RRC signaling/MAC signaling, physical layer resources can be saved.

Optionally, in the embodiment of the present application, if the first information is used to indicate the type of electronic device that generates self-interference, the terminal device may also send third information to the network device, where the third information is used to indicate the terminal device The type of device that can generate self-interference in, and at least one of interference frequency, interference bandwidth, interference intensity, and interference duration corresponding to the type of device that can generate self-interference.

The at least one of interference frequency, interference bandwidth, interference intensity and interference duration corresponding to the type of device that can generate self-interference mentioned above can be understood as: At least one of the frequency, bandwidth, intensity, and duration of the interference. For example, the type of device that can generate self-interference is the display screen, and the interference frequency generated by the display screen is 900M, then the corresponding interference frequency of the display screen is 900M.

Specifically, the terminal device may first report to the network device which electronic device types may cause self-interference, and at the same time, the terminal device may report to the network device the interference frequency, interference bandwidth, interference intensity and interference duration corresponding to the device type capable of generating self-interference At least one of time. Then, when the self-interference is reported, only the type of the electronic device can be reported, so that the network device can determine at least one of interference frequency, interference bandwidth, interference intensity, and interference duration according to the type of the electronic device.

In this way, it is possible to save the signaling or resource overhead caused by the terminal device reporting to the network device the existence of various characteristics of self-interference, such as interference frequency, interference bandwidth, and interference intensity.

Optionally, the terminal device may send the third information to the network device after accessing the network. At this time, self-interference may not have occurred. That is, the terminal device may send the third information to the network device before self-interference occurs.

Optionally, the correspondence between the type of device that can generate self-interference and at least one of interference frequency, interference bandwidth, interference intensity, and interference duration may be preset on the terminal device.

For example, since self-interference is generated by electronic devices inside the terminal equipment, the interference frequency, interference bandwidth, interference intensity, and interference duration can be obtained through tests in advance. For example, it is tested during the terminal device design or production process, so that the correspondence between the type of device that can generate self-interference and at least one of interference frequency, interference bandwidth, interference intensity and interference duration is preset on the terminal device .

Optionally, in the embodiment of the present application, before the terminal device sends the first information to the network device, the terminal device may also send the fourth information to the network device when it knows that self-interference operated by the electronic device is about to occur, where, The fourth information is used to predict to the network equipment that self-interference will occur in the terminal equipment.

Specifically, for the terminal device, the terminal device can predict the actual generation 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).

For 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 be predicted 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.

Optionally, the fourth information may be used to indicate the interval between the generation time of self-interference and the transmission time of the fourth 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 fourth information, that is, how long after the transmission of the specific fourth information will There will be self-interference.

Of course, in the embodiment of the present application, the terminal device may send the fourth information to the network device at a specific time before the occurrence of self-interference, for example, sending the fourth 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 fourth information.

Optionally, the method according to the embodiment of the present application may further include: the terminal device determines that when the self-interference occurs, the self-interference cannot be predicted to the network device in advance by the first duration.

At this time, self-interference can be caused by memory read and write. 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.

Among them, there may be a first duration of the prediction, that is, if the current time and the time when the self-interference will occur is less than the first duration, the prediction of the self-interference will no longer be performed.

The first duration mentioned above may be preset on the terminal device, or may be configured by the network device. Specifically, the network device may send indication information to the terminal device, where the indication information is used to indicate the first duration.

Optionally, in the embodiment of the present application, different service types correspond to different first durations.

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 types of services, such as terminals supporting Internet of Vehicles (V2X) and 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 embodiment of the present application, the network device may notify the terminal device in the form of general signaling (for example, broadcast signaling) or dedicated signaling (RRC signaling), when the terminal device cannot predict a certain self by at least Xms in advance When interfering, 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 terminal device may select the method for predicting self-interference according to the interval between the time when the self-interference is learned (that is, the time when the fourth 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.

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

It should be understood that some self-interference occurs unpredictably or in a short time in advance, then the terminal device may not send the above fourth information to the network device. For example, for self-interference caused by memory read and write, since the memory read and write is often initiated by the operating system, rather than completely triggered by user behavior, the terminal device cannot predict the self-interference caused by memory read and write.

In the embodiment of the present application, the terminal device may report the self-interference generated by the operation of the electronic device inside the terminal device to the network device, so that the network device may perform reasonable scheduling on the terminal device based on the report of the terminal device to avoid interference with downlink reception , Which can improve communication performance.
