Depending on the source of the self-interference signal, the self-interference can be divided into three categories:

The first type of self-interference signal may be, among other things, 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 signals originate from interference between different wireless communication modules within the terminal device, e.g. between WiFi signals and cellular signals.

The third type of self-interference signals mainly originate from electromagnetic waves generated by some active electronics inside the terminal equipment. For example, electromagnetic waves generated by electronic devices such as a display screen of a terminal device, a memory reading device of the terminal device, a camera of the terminal device, and an electric motor. The frequency range of the electromagnetic wave can be tens to hundreds of MHz, and when the harmonic wave falls on the cellular frequency band or intermodulation is generated between the harmonic wave and a transmitting signal of the cellular frequency band, the electromagnetic wave can interfere with the receiving of the cellular frequency band.

The third type of self-interference has two main characteristics: (1) The third type of self-interference originates from whether certain devices inside the terminal equipment are used. For example, for self-interference from a display screen, if the display screen is not open, the self-interference is not present. As another example, self-interference generated by the electric motor is only present when the electric motor is running. (2) The frequencies generated by the third type of self-interference are relatively fixed, and the bandwidths are generally relatively narrow.

For the third type of interference, the third type of interference exists only when certain devices inside the terminal device are operating. Whether these devices start to operate or not, however, depends on the user behavior of the terminal device and the working behavior of the terminal device itself, which is not visible to the network side.

In view of this, the embodiment of the application proposes a method for reporting self-interference, in which a terminal device may report self-interference generated by operation of an electronic device inside the terminal device to a network device, so that the network device may reasonably schedule the terminal device based on reporting of the terminal device, so as to avoid interference of downlink reception, and thus may improve communication performance.

And the self-interference bandwidth generated by the internal electronic device is usually relatively narrow, so that the network equipment can relatively easily avoid the self-interference bandwidth when knowing the self-interference.

Fig. 2 is a schematic flow chart of a communication method 200 according to an embodiment of the present application. The method 200 may be performed by a terminal device and may include at least some of the following.

In 210, the terminal device sends first information to the network device, the first information indicating that the terminal device currently has self-interference, wherein the self-interference is generated by operation of electronic components inside the terminal device.

Fig. 3 is a schematic flow chart 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 some of the following.

In 310, the network device receives first information sent by the terminal device, the first information being used to indicate that the terminal device currently has self-interference, wherein the self-interference is generated by operation of electronics within the terminal device.

The communication method according to the embodiment of the present application will be further described below with reference to fig. 2 and 3. It should be understood that in the embodiment, from the terminal device side angle description, it is understood that the terminal device receives from the network device, meaning that the network device has transmitted.

In this embodiment, the self-interference generated by the operation of the electronic device in the terminal device may be understood as a self-interference signal generated by the operation of the electronic device, and these self-interference signals will generate interference to the downlink signal received by the terminal device at the same time, where the received downlink signal may or may not exist when the self-interference is generated by the operation of the electronic device.

In an embodiment of the present application, the electronic device generating self-interference includes at least one of:

A display screen of the terminal device;

memory read-write device of terminal equipment;

a camera of the terminal device;

an electric motor of the terminal device.

Of course, in the embodiment of the present application, the electronic device that generates the self-interference may further include other electronic devices, which is not specifically limited in the embodiment of the present application.

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 may predict the operation duration of the electronic device, that is, the terminal device may predict the duration of self-interference, so that the terminal device may report the duration of self-interference to the network device, and the network device may reasonably schedule the terminal device based on the duration, for example, may avoid downlink scheduling of the terminal device during the duration.

The terminal equipment can predict the operation time of some electronic devices, and the terminal equipment can not predict the operation time of some electronic devices.

For example, for self-interference generated by memory read-write, since the memory read-write is controlled by the operating system, the terminal device can easily obtain the duration of the memory read-write, so that the terminal device can report the duration of the self-interference to the network device. However, for the run time of the screen or camera, the terminal device cannot predict, and in this case the duration of the self-interference may not be included in the first information.

It should be appreciated that for a third type of interference, the duration of the self-interference may be on the order of seconds.

(2) Self-interference generating electronic device type

Specifically, since the frequencies, bandwidths and/or intensities of the self-interference may be different due to different electronic device types, the terminal device may report the type of the electronic device that generates the self-interference, such as the self-interference generated by the display screen or the self-interference generated by the memory reading device or the electric motor, to the network device, so that the network device may determine the interference frequency, the interference bandwidth, the interference intensity, and the like of the self-interference according to the type of the electronic device.

The interference frequency, the interference type and the interference intensity of the self-interference generated by various electronic devices can be preset on the network side, or can be reported to the network side by the terminal equipment, specifically, the terminal equipment can report the type of the electronic devices capable of generating the self-interference in the terminal equipment to the network equipment, and the interference frequency, the interference bandwidth and/or the interference intensity of the self-interference generated by the electronic devices of various types. When the terminal equipment reports the self-interference to the network side, the type of the electronic device can be reported to the network side, so that the network equipment can judge the interference frequency, the interference bandwidth, the interference intensity and the like of the 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 may generate the following three types of interference to the downstream received signal: intermodulation (IM) interference, harmonic (Harmonic) interference, and Harmonic Intermodulation (Harmonic Mixing) interference.

For intermodulation interference, the frequencies of the intermodulation signals of a certain order, which are self-interfering signal 1 (which may be generated by the operation of the electronic device) and self-interfering signal 2 (which may be generated by the operation of the electronic device or as an uplink transmit signal), overlap or partially overlap with the downlink signal frequency of a certain carrier F1. The self-interference signal 1 and the self-interference signal 2 constitute intermodulation interference to the downlink signal of carrier 1.

For example, the memory read-write will generate a signal about 1G, and the 3.5G cellular transmission signal will generate a 2-order intermodulation signal, and interfere with the 2.6G cellular reception signal, so when the self-interference signal of the memory read-write is generated, the interference frequency that the terminal device can report to the network device is 1G.

For harmonic interference, the frequency multiplication of the frequency of the self-interference signal 1 (which may be generated by the operation of an electronic device) overlaps or partially overlaps with the frequency of the downlink signal of a certain carrier 1, so that the self-interference signal 1 forms harmonic interference to the downlink signal of the carrier 1.

For example, the display screen may generate a signal with a frequency of about 450M, and the 2 nd harmonic 900M and the 4 th harmonic 1.8G may interfere with the reception of the cellular band, so that when the self-interference of the screen is generated, the terminal may report to the network device that the interference frequency is 900M and 1.8G.

For harmonic intermodulation interference, the frequency multiplication of a certain carrier 1 overlaps or partially overlaps the frequency of the self-interference signal 1 (and the adjacent frequency thereof), so that the downlink signal of the carrier 1 by the carrier self-interference signal 1 forms the harmonic intermodulation interference. At this time, the terminal device may report the frequency of the self-interference signal to the network side.

(4) Interference bandwidth for self-interference

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

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

(5) Interference strength of self-interference

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

For example, if the interference strength of the self-interference is greater than or equal to the interference strength threshold, the network device may determine to avoid the self-interference; if the interference strength of the self-interference is less than the interference strength 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, and it should be understood that in this embodiment of the present application, the first information may include multiple information (for example, information that there is self-interference currently, duration of self-interference, interference strength of self-interference, etc.), where the multiple information may be carried in the same signaling or may be carried 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 frequency at which the display screen produces self-interference may be 900M and 1.8G, and the frequency at which the memory read device produces self-interference may be 1G.

In the embodiment of the present application, the terminal device sends the first information to the network device, which may include: the terminal device may send the first information to the network device upon determining that the self-interference is generated.

For example, when some electronic device, such as an electric motor, inside the terminal device starts to operate, the terminal device may determine that electromagnetic waves generated by the electronic device may cause self-interference to a downlink reception signal of the terminal device, and at this time, the terminal device may send the first information to the network device.

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

The self-interference exists in the process of establishing connection between the terminal equipment and the network equipment, and can be understood as follows: when the self-interference is generated, the terminal equipment does not establish formal wireless link connection with the network equipment, and the self-interference is still continuous in the process of establishing connection between the terminal equipment and the network equipment; or, self-interference is generated in the process of establishing connection between the terminal equipment and the network equipment.

In an embodiment, the terminal device may carry the first information in any uplink message sent.

Illustratively, when the terminal device transmits the first information in the process of establishing a connection with the network device, the terminal device may transmit the first message to the network device through message 1 (Msg 1) or message 3 (Msg 3). I.e. the terminal device may send a first message to the network device during random access via Msg1 or Msg 3.

In this way, the terminal device can report to the network device that there is self-interference currently at the fastest speed.

Further exemplary, the terminal device may send the first information to the network device through a connection reestablishment message.

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

Regarding the signaling type employed by the terminal device to send the first information, in an embodiment, the network device may pre-configure the signaling type employed by the terminal device to send the first information, and then send configuration information to the terminal device, where the configuration information may include the signaling type employed by the terminal device to send the first information. After receiving the configuration information, the terminal device may determine a signaling type used for sending the first information.

The configuration information may be carried in downlink control information (Downlink Control Information, DCI), radio resource control (Radio Resource Control, RRC) or signaling medium access control (Media Access Control, MAC) signaling, among others.

In the process that the network device determines the signaling type adopted by the terminal device to send the first information, as an example, the network device may determine the signaling type adopted by the terminal device to send the first information according to whether downlink scheduling exists at the current time.

If the terminal equipment has downlink scheduling at the current moment, the network equipment can determine that the signaling type bearing the first information is physical layer signaling.

It should be appreciated that since the self-interference, once generated, will interfere with the downlink received signal, the faster the network device knows that the self-interference has been generated, so that the network device can avoid the self-interference by adopting a scheduling method. Therefore, the best effect is that the terminal device can send the first information to the network device using physical layer signaling.

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

For PUCCH, the network device may configure PUCCH resources dedicated to transmitting the first information for the terminal device. When the terminal device transmits the first information to the network device, the first information may be transmitted on the configured resources using the determined PUCCH format (format).

Wherein, the content of the first information bearer is different, and the PUCCH formats may be different.

For UCI in PUSCH, the terminal device may multiplex the data channel for transmission of the first information.

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

In an embodiment, the terminal device may select signaling to be used for transmitting the first information according to the duration of the self-interference and/or the interference strength of the self-interference.

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

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

In the embodiment of the present application, when the terminal device reports that self-interference exists to the network device, at least one of an electronic device type generating self-interference, an interference frequency of self-interference, an interference bandwidth of self-interference, an interference strength of self-interference, and a duration of self-interference may be reported to the network device at the same time.

For example, inserting information bits in PUCCH or UCI for indicating that self-interference currently exists indicates an interference frequency of self-interference, or adding a corresponding domain to RRC or MAC signaling indicating that self-interference currently exists indicates an interference frequency of self-interference.

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

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

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

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 will be appreciated that the faster the network device knows the better when self-interference disappears, so that the network device can schedule on previously interfered resources, in which case the second information can be carried in physical layer signaling; when the second information is carried in the RRC signaling/MAC signaling, physical layer resources can be saved.

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

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

Specifically, the terminal device may report to the network device which electronic device types may generate self-interference, and at the same time, the terminal device may report to the network device at least one of an interference frequency, an interference bandwidth, an interference strength, and an interference duration corresponding to the device types capable of generating self-interference. When the self-interference is reported later, only the type of the electronic device can be reported, so that the network equipment can judge at least one of interference frequency, interference bandwidth, interference intensity and interference duration according to the type of the electronic device.

Thus, the signaling or resource cost caused by the characteristics of self-interference such as interference frequency, interference bandwidth, interference intensity and the like, which are reported to the network equipment by the terminal equipment, can be saved.

In an embodiment, the terminal device may send the third information to the network device after accessing the network. At this time, self-interference may not yet occur. That is, the terminal device may transmit the third information to the network device before the self-interference is generated.

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

For example, since self-interference is generated by electronics inside the terminal device, interference frequency, interference bandwidth, interference strength, interference duration, etc. can be obtained through testing in advance. For example, it is tested during the design or production of the terminal device, so that the correspondence between the device type, which can generate the interference, and at least one of the interference frequency, the interference bandwidth, the interference strength and the interference duration is predefined at the terminal device.

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 fourth information to the network device when it is known that self-interference running by the electronic device is about to occur, where the fourth information is used to predict, to the network device, that self-interference is about to occur inside the terminal device.

In particular, for the terminal device, the terminal device may predict the actual generation time of the self-interference.

For example, for self-interference generated by a screen, a terminal device may predict the occurrence of self-interference in advance by user behavior. For example, when the user uses a program for timing a reminder or an alarm clock, the terminal device can know in advance when the screen will be turned on (because both the reminder and alarm functions of the terminal device are accompanied by functions of screen activation).

For another example, when the user activates the screen by means of a key or touch screen, there may be a short interval, such as 0.1s, from the time the user's action occurs until the actual screen is activated, which is actually known to the terminal device.

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

These delays, while short, such as the screen or camera delays mentioned above, are activated, such as 0.1s, for cellular communication systems, network devices can already avoid scheduling downstream transmissions on the interfered frequency if the system can be predicted several tens of ms in advance. It would be highly advantageous for terminals and systems to be immune to interference if the terminals could predict the impending self-interference to the network device in advance.

In an embodiment, the fourth information may be used to indicate an interval between a generation time of the self-interference and a transmission time of the fourth information.

Specifically, since the terminal device predicts that self-interference will occur in the terminal device to the network device, and specifically when the self-interference occurs, the network device can further notify the network device, in this case, the network device can further accurately know the occurrence time of the self-interference, thereby realizing more reasonable scheduling of the terminal device. The notification of when the self-interference is generated may be implemented by notifying an 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 fourth information, the self-interference will exist.

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 self-interference occurs, for example, the fourth information is sent to the network device at a time 50ms from before the self-interference occurs, and then the network device may learn that the self-interference will occur at a time 50ms after the fourth information is received.

The method of the embodiment of the application can further comprise the following steps: the terminal device determines that the self-interference cannot be predicted to the network device in advance for the first duration when the self-interference is generated.

At this time, the self-interference may be caused by memory read-write. For example, the terminal device may delay the execution of the memory read/write by the operating system of the terminal device for a relatively short time (e.g., 1-5 ms) (a longer delay may reduce the user experience, and thus is not a good choice), and this delay may be the time that the terminal device may forecast in advance. But the prediction of self-interference several ms in advance may not be of great use to the network device, whereby the terminal device may not predict to the network device that this self-interference is about to occur.

Wherein, there may be a first duration of the forecast, that is, if the current time and the time when the self-interference is about to occur are less than the first duration, the forecast of the self-interference is not performed any more.

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 time length.

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

The traffic types in embodiments of the present application may include high reliability low latency (Ultra-Reliable Low latency Communications, URLLC) traffic and enhanced mobile broadband (Enhance Mobile Broadband, eMBB) traffic. In addition to the above mentioned eMBB and URLLC services, there may actually be terminals supporting more service types, such as terminals supporting internet of vehicles (Vehicle to anything, V2X), industrial internet of things (Industrial Internet of Things, IIoT) services, where the service types of embodiments of the present application may include V2X services and IIoT services.

In the embodiment of the application, the network device may notify the terminal device in the form of general signaling (e.g., broadcast signaling) or dedicated signaling (RRC signaling), and when the terminal device cannot predict a self-interference at least in advance of Xms, the self-interference does not need to be predicted. This Xms may be the same for all terminal devices when general signaling is used and different terminal devices when dedicated signaling is used.

For example, for a terminal device using the eMBB service, x=20 ms, and for a terminal device using the URLLC service, x=5 ms. This is because the scheduling period and reliability requirements of the network devices for different services are different, and for an eMBB, just advancing the 5ms forecast does not help the network devices avoid interference (scheduling of the network devices may be done 10-20 ms before the actual downlink transmission occurs). But for URLLC traffic, the delay, especially the reliability, requirements are high, and the 5 ms-ahead predictive interference can help the network device avoid interference.

The network device may also inform the terminal device in the form of general signaling (e.g. broadcast signaling) or dedicated signaling (RRC signaling), the terminal device does not need to predict to the network device that some self-interference will occur more than Yms a time in advance, such as: y=200 ms. That is, the terminal device needs to report to the network side only when interference is about to occur within 50 ms.

In the embodiment of the present application, the terminal device may select signaling used for predicting the self-interference according to an interval between a time at which the self-interference will occur (i.e., a time at which the above fourth information may be transmitted) and a time at which the self-interference occurs.

For example, for self-interference occurring within 50ms, physical layer signaling reporting is employed; for self-interference to occur within 50 ms-200 ms, MAC or RRC signaling reporting may be employed. The self-interference generated in a short time is reported to the network as soon as possible by adopting physical layer signaling, so that the network equipment is helped to avoid the interference by adopting reasonable scheduling; and for the interference occurring in a relatively long time, the MAC/RRC signaling is adopted, so that the physical layer resource is saved.

Or, the network device may send fifth information to the terminal device, where the fifth information indicates a correspondence between an interval and a signaling type, and the interval is an interval between a generation time of self-interference and a transmission time of the fourth information; after receiving the fifth information, the terminal device may determine a signaling type of signaling carrying the fourth information based on the fifth information.

It will be appreciated that some self-interference may occur unpredictably or in a short period of time, and the terminal device may not send the fourth information to the network device. For example, for self-interference generated by memory read-write, since memory read-write is often initiated by an operating system, but not completely triggered by user behavior, the self-interference generated by memory read-write cannot be predicted by the terminal device.

According to the method and the device for scheduling the downlink receiving, the terminal equipment can report the self-interference generated by the operation of the electronic devices in the terminal equipment to the network equipment, so that the network equipment can reasonably schedule the terminal equipment based on the report of the terminal equipment, the downlink receiving is prevented from being interfered, and the communication performance can be improved.
