For ease of understanding, terms involved in this embodiment of the present application are firstly introduced below in conjunction with FIG. 2 to FIG. 4 .

Receiver Sensitivity

Receiving sensitivity is used to characterize the minimum average received signal strength that terminal equipment can receive correctly. Generally, the higher the receiving sensitivity of a terminal device is, the lower the minimum received signal strength supported by the terminal device is. The lower the receiving sensitivity of the terminal device is, the higher the minimum received signal strength supported by the terminal device is.

In some cases, the terminal equipment will be affected by factors such as interference (for example, harmonic interference and/or intermodulation interference) or noise, which will affect the receiving sensitivity of the terminal equipment, causing the receiving sensitivity of the terminal equipment to a certain extent This phenomenon is called "receive sensitivity rollback".

Harmonic interference and intermodulation interference

In a communication system (for example, NR system), there are many situations that cause sensitivity back-off, especially when a terminal device works in a frequency band combination scenario, many frequency band combinations will interfere with each other, causing the receiving sensitivity of the terminal device to back off. For example, in scenarios such as UMTS terrestrial radio access network-new radio dual connection (EUTRA-NR dual connection, EN-DC), dual connection (dual connection, DC) or inter-band carrier aggregation (carrier aggregation, CA), the terminal The device will cause the receiving sensitivity to fall back due to harmonic interference or intermodulation interference.

In some cases, the harmonic interference and intermodulation interference in terminal equipment mainly come from the nonlinearity of RF front-end devices. Nonlinear devices can be divided into two categories: passive devices and active devices. Among them, nonlinear passive devices include filters, duplexers, etc. Nonlinear active devices include switches, power amplifiers (power amplifier, PA) and so on. Generally, the harmonics and intermodulation interference generated by passive devices are generally weaker than those of active devices, and PA is the main nonlinear source in active devices.

When the input of the nonlinear device is a monotone signal cos(ωt), the output signal of the nonlinear device will contain higher harmonic components such as 2ωt and 3ωt. If these high-frequency harmonic components fall into the receiving frequency band of the terminal equipment, harmonic interference will be generated. The above-mentioned harmonic interference mostly occurs in scenarios where low-frequency transmission and high-frequency reception are performed simultaneously.

In addition, when the input signal of the nonlinear device contains multiple frequency components, the output signal of the nonlinear device will contain various order intermodulation products of the above multiple frequency components. Assuming that the input signal of the nonlinear device contains two frequency components: cos(ω ₁ t) and cos(ω ₂ t), then the output of the nonlinear device will contain second-order intermodulation products (ω ₁ ±ω ₂ ), three order intermodulation products (2ω ₁ ±ω ₂ ,ω ₁ ±2ω ₂ ), etc. If the above-mentioned intermodulation products fall into the receiving frequency band of the terminal equipment, intermodulation interference will be caused. This kind of intermodulation interference mostly occurs in scenarios where high and low frequencies are transmitted simultaneously, or in scenarios where external signals are poured back into the transmission link of the terminal device. The following will introduce the harmonic interference and intermodulation interference generated between the frequency band B3 and the frequency band n77 in conjunction with FIG. 2 as an example.

Fig. 2 is a schematic diagram of harmonic interference and intermodulation interference generated between frequency band B3 and frequency band n77. Referring to Figure 2, it is assumed that the terminal device supports communication under the frequency band combination, the frequency band combination includes frequency band B3 and frequency band n77, wherein the frequency range corresponding to the transmission frequency band of frequency band B3 is 1710MHz to 1785MHz, and the frequency range corresponding to the reception frequency band of frequency band B3 is 1805MHz to 1880MHz, the corresponding frequency range of frequency band n77 is 3300MHz to 4200MHz.

On the one hand, the terminal device sends the first signal (for example, an uplink signal) on the frequency band B3 and occupies the frequency band from 1710MHz to 1785MHz. After the first signal is output by the nonlinear device of the terminal device, the second harmonic generated by the output signal The frequency range corresponding to the component is 3420HMz to 3570MHz, which just falls into the frequency domain range of the frequency band n77, and will cause harmonic interference to the signal (eg, downlink signal) received by the terminal equipment through the frequency band n77.

On the other hand, the terminal device sends a second signal (for example, an uplink signal) on the frequency band n77, and the output signal of the second signal after passing through the nonlinear device will contain second-order intermodulation products, and the second-order intermodulation The frequency range of the product is 1515MHz to 2490MHz, which just includes the frequency range corresponding to the frequency band B3. Therefore, the above-mentioned second-order intermodulation product will cause intermodulation interference to received signals (such as downlink signals) on the frequency band B3.

In other cases, the above-mentioned harmonic interference and intermodulation interference may also be caused by leakage between links inside the terminal equipment. The following describes the causes of harmonic interference and intermodulation interference in conjunction with Figure 3 .

Fig. 3 is a schematic diagram of the structure of a terminal device. The terminal device shown in FIG. 3 includes a transmission chain 310 of frequency band B3 and a transmission chain 320 of frequency band n77. On the one hand, when the signal is conducted in the transmission chain in the terminal device, it will cause interference to other paths. For example, interference (eg, second harmonics) generated when a signal is transmitted through transmit link 310 may affect signals in transmit link 320 . On the other hand, the interference generated in the printed circuit board (printed circuit board, PCB) where the transmitting branch 310 is located will directly leak into the transmitting link 320 of the terminal device through the PCB leakage path 330, and cause interference to the transmitting link 320. interference.

Generally, for the interference generated during signal conduction, it is possible to suppress harmonic interference and intermodulation interference by adding a filter to the transmission link. As for the interference generated through the PCB leakage path 330, it is necessary to isolate the PCB, or adjust the layout of the PCB in the terminal device to avoid it. However, this usually depends on the design of the terminal equipment, and the ultimate suppression of interference will vary greatly for different terminal equipment.

Based on the above introduction, it can be seen that harmonic interference and intermodulation interference will seriously affect the receiving sensitivity of terminal equipment. In some cases, the second harmonic interference and second-order intermodulation products may cause the receiving sensitivity of the terminal equipment to drop by tens of decibels, resulting in a significant reduction in the downlink receiving coverage of the terminal equipment. FIG. 4 shows a schematic diagram of changes in downlink receiving coverage of a terminal device. Referring to Figure 4, in the absence of harmonic interference and intermodulation interference, the receiving coverage of the terminal equipment is originally the range 410, but in the presence of harmonic interference and intermodulation interference, the terminal equipment will shrink from the range 410 to range 420.

At present, in order to avoid that the sensitivity of the terminal device falls back greatly under some frequency band combinations, the network device cannot communicate with the terminal device. The maximum sensitivity degradation (MSD) corresponding to different frequency band combinations is defined in the standard to represent the maximum value of the receiving sensitivity degradation of terminal equipment in the corresponding frequency band combination. In this way, before configuring the first frequency band combination for the terminal device, the network device can first determine the MSD corresponding to the defined first frequency band combination in the standard, and judge whether to configure the first frequency band for the terminal device based on the MSD corresponding to the first frequency band combination combination. That is to say, the MSD represents the maximum value of the receiving sensitivity rollback of the terminal equipment allowed by the standard for the frequency band combination with interference.

Simultaneous sending and receiving capability

The above simultaneous transceiving capability is used to indicate that the terminal device can receive signals through another frequency band of the frequency band combination when transmitting signals through one frequency band of the frequency band combination. For example, frequency band combination 1 includes frequency band A and frequency band B, and the above-mentioned simultaneous sending and receiving capability means that the terminal device can also receive signals through frequency band B while transmitting signals through frequency band A. The following describes the simultaneous sending and receiving capability of the terminal device by taking frequency band combination 1 including frequency band A and frequency band B as an example with reference to FIG. 5 and FIG. 6 .

Referring to Figure 5, assuming that the terminal device transmits an uplink signal through the transmission frequency band of frequency band A, the frequency range of the harmonic generated by the signal is at least partially overlapped with the frequency range corresponding to frequency band B, then the uplink signal may be affected by The downlink signal received by the terminal device through the frequency band B is affected, causing the receiving sensitivity of the terminal device to receive the downlink signal through the frequency band B to drop greatly. In this case, the terminal equipment does not support simultaneous transmit and receive capability in Band Combination 1.

Referring to Figure 6, it is assumed that the terminal device transmits signal A and signal B through frequency band A and frequency band B at the same time, and the frequency range corresponding to the intermodulation product generated by signal A and signal B overlaps partially or completely with the frequency range of the receiving frequency band of frequency band A . Then, the intermodulation product will interfere with the signal received through the receiving frequency band of the frequency band A, resulting in a large fallback in the receiving sensitivity of the terminal device under the receiving frequency band of the frequency band A. In this case, the terminal equipment does not support simultaneous transmit and receive capability in Band Combination 1.

It should be noted that, in addition to the scenarios shown in FIG. 5 and FIG. 6 , there are other scenarios that may cause the terminal device to fail to support the simultaneous sending and receiving capability under the combination of frequency bands. For example, if the interval between two frequency bands in the frequency band combination is too small, the transmission and reception of signals in one frequency band will interfere with the transmission and reception of signals in the other frequency band, and the terminal equipment cannot support the simultaneous transmission and reception capability under this frequency band combination. .

At present, in order to prevent the network device from configuring an inappropriate frequency band combination for the terminal device, interference will be generated when the terminal device simultaneously transmits and receives signals on the configured frequency band combination, resulting in the inability to transmit and receive signals correctly. The protocol stipulates that the terminal device can inform the network device whether the terminal device supports the simultaneous transceiving capability on the frequency band combination by sending or not sending the simultaneous transceiving capability (simultaneousRxTx) to the network device. In some implementation manners, if the terminal device sends the foregoing simultaneous transceiving capability to the network device, the network device considers that the terminal device supports the simultaneous transceiving capability under the combination of frequency bands. In some other implementation manners, if the terminal device does not send the simultaneous sending and receiving capability to the network device, the network device may consider that the terminal device does not support the simultaneous sending and receiving capability under the frequency band combination.

As mentioned above, in the traditional technology, in order to avoid interference caused by the terminal equipment under the combination of frequency bands, resulting in a large fallback of the receiving sensitivity of the terminal equipment, the network equipment will be based on the protocol before configuring the first frequency band combination for the terminal equipment. The MSD corresponding to each frequency band combination is predefined, the MSD corresponding to the first frequency band combination is determined, and based on the MSD corresponding to the first frequency band combination, it is determined whether to configure the first frequency band combination for the terminal device. In some cases, if the network device determines that the MSD corresponding to the first frequency band combination is relatively large, the network device will not configure the first frequency band combination for the terminal device. In other cases, if the network device considers that the MSD corresponding to the first frequency band combination can be tolerated, the network device configures the first frequency band combination for the terminal device.

However, the scheme in which the network device determines whether to configure the first frequency band combination for the terminal device based on the MSD corresponding to each predefined frequency band combination will cause the frequency band combination corresponding to a higher MSD in the protocol to always be unusable.

In some cases, for a terminal device with high receiving sensitivity, even if it works in a frequency band combination corresponding to a high MSD, the terminal device has undergone a large sensitivity back-off, and the remaining receiving sensitivity of the terminal device is still relatively high . Then this kind of terminal equipment can actually use frequency band combination to communicate. However, based on the frequency band combination configuration mechanism described above, the network device will not configure the frequency band combination corresponding to the MSD for the terminal device at all, which leads to the fact that the frequency band combination corresponding to a higher MSD in the protocol cannot be used.

In other cases, based on the principles of harmonic interference and intermodulation interference introduced above, it can be seen that the anti-interference capabilities of terminal devices vary greatly. Even if they work in the same combined frequency band, the actual Receive sensitivity back-off is also different. For a terminal device with high anti-interference ability, the actual receiving sensitivity fallback of the terminal device may be smaller than the MSD corresponding to the frequency band combination in the protocol. In this case, the terminal device can actually use the frequency band combination to communication. However, based on the frequency band combination configuration mechanism introduced above, the network device will not configure the frequency band combination corresponding to the MSD for the terminal device at all, which also leads to the fact that the frequency band combination corresponding to a higher MSD in the protocol cannot be used.

In order to avoid the above problems, the embodiment of the present application provides a communication method, the terminal device can send the actual interference strength of the terminal device under the first frequency band combination to the network device through the first indication information, so that the network device can to determine whether to configure the first frequency band combination for the terminal device, so as to improve the utilization rate of the frequency band combination in the communication system. The following describes the communication method in the embodiment of the present application with reference to FIG. 7 .

FIG. 7 is a flowchart of a communication method according to an embodiment of the present application. The method shown in FIG. 7 includes steps S710 to S720.

In step S710, the terminal device sends first indication information to the network device.

The first indication information is used to indicate the actual interference intensity of the terminal device under the first frequency band combination. Wherein, the first frequency band combination may include multiple frequency bands. For example, frequency band B3 and frequency band n77 referred to above may be included.

In some implementation manners, the foregoing actual interference strength may be represented by interference power. In other implementation manners, the foregoing actual interference intensity may be represented by an actual MSD of the terminal device under the first frequency band combination. Under the first frequency band combination, the higher the actual MSD of the terminal device is, the higher the actual interference intensity received by the terminal device is. Under the first frequency band combination, the lower the actual MSD of the terminal device is, the lower the actual interference intensity received by the terminal device is. In other implementation manners, the foregoing actual interference intensity may be represented by receiving sensitivity of the terminal device. Under the first frequency band combination, the higher the actual receiving sensitivity of the terminal device is, the lower the actual interference intensity received by the terminal device is. Under the first frequency band combination, the lower the actual receiving sensitivity of the terminal device is, the higher the actual interference intensity received by the terminal device is. Of course, other parameters may also be used in the embodiment of the present disclosure to represent the actual interference intensity. For example, it may be represented by an actual receiving sensitivity backoff value of the terminal device.

In addition, in some implementation manners, the above first indication information may be carried in radio resource control (Radio Resource Control, RRC) signaling. Of course, in the embodiment of the present application, the above-mentioned first indication information may also be carried in dedicated signaling, which is not specifically introduced in the embodiment of the present application.

In step S720, the network device determines whether to configure the first frequency band combination for the terminal device based on the first indication information. In other words, the network device determines whether to configure the first frequency band combination for the terminal device based on the actual interference intensity.

The above configuration of the first frequency band combination for the terminal device can be understood as configuring resources (including frequency domain resources, time domain resources and/or space resources) in each frequency band in the first frequency band combination for the terminal device, so that the terminal device can pass through the first frequency band Combination for communication.

In some implementation manners, the network device may determine whether to configure the first frequency band combination for the terminal device based on the magnitude between the actual interference intensity and the interference intensity threshold. In some other implementation manners, the network device may also directly determine whether to configure the first frequency band combination for the terminal device based on the actual interference intensity. The specific manner in which the network device in this embodiment of the present application determines whether to configure the first frequency band combination for the terminal device is not limited.

In this embodiment of the present application, the terminal device can send the actual interference intensity of the terminal device under the first frequency band combination to the network device through the first indication information, so that the network device can determine whether to configure the terminal device based on the actual interference intensity. The first frequency band combination is used to improve the utilization rate of the frequency band combination in the communication system. In the traditional solution, the network device determines whether to configure the first frequency band combination for the terminal device based on the MSD corresponding to each frequency band combination defined in advance, so that the frequency band combination corresponding to a higher MSD in the protocol cannot be used all the time.

Usually, sending the actual interference intensity from the terminal device to the network device will occupy more bits in the first indication information, resulting in a large overhead for transmitting the first indication information. Therefore, in order to reduce the overhead of transmitting the first indication information, the terminal device can be configured to send the comparison result between the actual interference intensity and the first preset value to the network device, and use the comparison result to indicate the actual interference of the terminal device to the network device strength.

That is, the above method further includes: the terminal device compares the actual interference intensity with the first preset value to obtain a comparison result; the terminal device generates first indication information, and the first indication information indicates the actual interference intensity based on the comparison result.

The above-mentioned first preset value is a value corresponding to the parameter representing the actual interference intensity. For example, when the actual interference intensity is represented by the actual MSD of the terminal device, the above-mentioned first preset value may be the MSD threshold. For another example, when the actual interference intensity is represented by the actual receiving sensitivity of the terminal device, the first preset value may be a receiving sensitivity threshold.

In some implementations, the above-mentioned first preset value can also be a level threshold of the interference intensity level, so that the terminal device can determine the interference intensity level where the actual interference intensity is based on the size between the actual interference intensity and the level threshold , and directly send the interference intensity level of the actual interference intensity to the network device, so that the network device determines whether to configure the first frequency band combination for the terminal device based on the interference intensity level of the actual interference intensity.

In some implementation manners, the terminal device may carry an identifier of an interference intensity level at which the actual interference intensity is located in the first indication information, so as to indicate the actual interference intensity of the terminal device.

It should be noted that the above-mentioned interference intensity level may include multiple levels, and the level thresholds corresponding to different levels in the multiple levels may be different. At this time, the level threshold corresponding to the above-mentioned first preset value may be one of the multiple level thresholds. one. For example, the above multiple levels include 3 levels, namely level 1, level 2 and level 3, wherein the interference intensity in level 1 is lower than that in level 2, and the interference intensity in level 2 is lower than that in level 3 Interference strength. In addition, the level threshold between level 1 and level 2 is level threshold 1, and the level threshold between level 2 and level 3 is level threshold 2. In this case, the above-mentioned first preset value may be level threshold 1, and of course, the above-mentioned first preset value may also be level threshold 2.

Certainly, the above-mentioned interference intensity level may also include only two interference intensity levels, then the level threshold corresponding to the above-mentioned first preset value may be a level threshold between the above-mentioned two interference intensity levels. For example, the above-mentioned interference intensity level includes two levels of high interference intensity and low interference intensity. In this case, the above-mentioned first preset value may be a level threshold between high interference intensity and low interference intensity.

In addition, the division manner of the foregoing interference intensity levels may correspond to the representation manner of the actual interference intensity. For example, the actual interference intensity is represented by an actual MSD, and the above interference intensity level may be an MSD level. For another example, the actual interference intensity is represented by actual receiving sensitivity, and the above interference intensity level may be the receiving sensitivity level.

For ease of understanding, the following will take the actual interference intensity through the actual MSD or actual receiving sensitivity as an example to introduce three ways for the terminal device to report the actual interference intensity to the network device in the embodiment of the present application.

Mode 1, the actual interference intensity is represented by the actual MSD, and the first preset value is the level threshold corresponding to the MSD level.

Assume that the MSD level includes 3 MSD levels, namely MSD level 1, MSD level 2 and MSD level 3, wherein the interference intensity in MSD level 1 is lower than that in MSD level 2, and the interference intensity in MSD level 2 is lower than Interference intensity in MSD class 3. That is to say, the MSD value in MSD level 1 is smaller than the MSD value in MSD level 2, and the MSD value in MSD level 2 is lower than the MSD value in MSD level 3. In addition, the level threshold between MSD level 1 and MSD level 2 is MSD level threshold 1, and the level threshold between MSD level 2 and MSD level 3 is MSD level threshold 2.

Correspondingly, the terminal device can compare the actual MSD with the above MSD level threshold, so as to determine the MSD level corresponding to the actual MSD. If the actual MSD is less than the level threshold 1, the MSD level corresponding to the actual MSD is MSD level 1. At this time, the terminal device may indicate to the network device that the MSD level corresponding to the actual MSD is MSD level 1 through the first indication information. If the actual MSD is greater than the MSD level threshold 1, and the actual MSD is less than the MSD level threshold 2, then the MSD level corresponding to the actual MSD is MSD level 2. At this time, the terminal device can indicate the MSD corresponding to the actual MSD to the network device through the first indication information The rating is MSD Class 2. If the actual MSD is greater than the MSD level threshold 2, then the MSD level corresponding to the actual MSD is MSD level 3. At this time, the terminal device may indicate to the network device that the MSD level corresponding to the actual MSD is MSD level 3 through the first indication information.

It should be noted that the above-mentioned MSD level threshold can be a positive integer, for example, the value of the above-mentioned MSD level threshold 1 can be 3dB, the value of the above-mentioned MSD level threshold 2 can be 6dB, and the value of the above-mentioned MSD level threshold 3 can be 9dB.

Assume that MSD levels include 2 MSD levels, namely MSD level 1 and MSD level 2. Among them, MSD level 1 corresponds to low interference intensity, and MSD level 2 corresponds to high interference intensity. That is, the MSD value in MSD class 1 is smaller than the MSD value in MSD class 2. In addition, the level threshold between MSD level 1 and MSD level 2 is MSD level threshold 1.

Correspondingly, the terminal device can compare the actual MSD with the above MSD level threshold, so as to determine the MSD level corresponding to the actual MSD. If the actual MSD is lower than the MSD level threshold, then the actual MSD corresponds to MSD level 1, indicating that the actual interference intensity of the terminal device is low interference intensity. If the actual MSD is higher than the MSD level threshold, the actual MSD corresponds to MSD level 2, indicating that the actual interference intensity of the terminal device is high interference intensity.

Then, the terminal device may indicate to the network device the level corresponding to the above-mentioned actual MSD through the above-mentioned first indication information. In some implementation manners, the terminal device may carry one of {low interference intensity indication, high interference intensity indication} in the first indication information to indicate the actual interference intensity. In other implementation manners, the network device may default the terminal device to be at low interference intensity, and when the terminal device determines that the actual interference intensity is high interference intensity (corresponding to MSD level 2), the terminal device may send the first indication information to the network device to The actual interference intensity is indicated. In this case, the first indication information may carry a low interference intensity indication. In other implementation manners, the network device may default the terminal device to be in a high interference intensity, and when the terminal device determines that the actual interference intensity is low interference intensity (corresponding to MSD level 1), the terminal device may send the first indication information to the network device to The actual interference intensity is indicated. At this time, the high interference intensity indication may be carried in the first indication information.

In this embodiment of the present application, the foregoing level threshold may be preconfigured or predefined. For example, the above grade threshold may be pre-configured by the network device. For another example, the above level threshold may also be predefined by a protocol.

If different class thresholds are configured for each terminal device, the complexity of configuring class thresholds will be increased to a certain extent. Therefore, in order to reduce the complexity of configuring the class threshold, in some implementation manners, the same class threshold may be configured for terminal devices belonging to the same cell. Of course, if the complexity of configuring the class threshold is not considered, different class thresholds may also be configured for terminal devices belonging to the same cell.

In some other implementation manners, it is assumed that the terminal device supports multiple frequency band combinations, and the multiple frequency band combinations include the foregoing first frequency band combination. In order to reduce the complexity of configuring the level threshold, the same level threshold may also be configured for different frequency band combinations in multiple frequency band combinations. Of course, if the complexity of configuring the level threshold is not considered, different level thresholds may also be configured for different frequency band combinations among the multiple frequency band combinations.

In some other implementation manners, it is assumed that the first frequency band combination includes multiple carrier combinations. In order to reduce the complexity of configuring the class threshold, the same class threshold may be configured for different carrier combinations in multiple carrier combinations. Of course, if the complexity of configuring the level thresholds is not considered, different level thresholds may also be configured for different carrier combinations among multiple carrier combinations.

Method 2: The actual interference intensity is represented by the actual receiving sensitivity, and the first preset value is a sensitivity reference value.

In some implementation manners, in order to make the solution of the present application compatible with existing communication protocols, the aforementioned sensitivity reference value may be a reference sensitivity corresponding to a frequency band defined in the communication protocol. For example, the existing communication protocol stipulates that the reference sensitivity corresponding to the frequency band B is -94dB. Certainly, if the solution of the present application is not considered to be compatible with the existing communication protocol, the above sensitivity reference value can also be redefined.

Correspondingly, the terminal device may determine the difference between the actual receiving sensitivity and the sensitivity reference value, and send the above difference to the network device through the first indication information. In some implementation manners, the above difference may be obtained by subtracting a sensitivity reference value from the actual receiving sensitivity. In some other implementation manners, the above difference may also be obtained by subtracting the actual receiving sensitivity from the sensitivity reference value.

Assume that the first frequency band combination includes frequency band A and frequency band B. The agreement stipulates that the reference sensitivity corresponding to frequency band B is -94dB, so the first preset value is -94dB. In the case that frequency band A interferes with frequency band B, the actual receiving sensitivity of the terminal equipment is -90dB. At this time, the above-mentioned difference is -4dB.

Assume that the first frequency band combination includes frequency band A and frequency band B. The agreement stipulates that the reference sensitivity corresponding to frequency band B is -94dB, so the first preset value is -94dB. When frequency band A interferes with frequency band B, the actual receiving sensitivity of the terminal equipment is -98dB. At this time, the above-mentioned difference is +4dB.

In some implementation manners, the terminal device may directly send the above difference to the network device. In some other implementation manners, the terminal device may also send the interval in which the difference is located to the network device through the first indication information. That is to say, the terminal device selects the interval where the difference is located from the multiple preset intervals, carries the identifier corresponding to the interval in the first indication information, and sends it to the network device. Correspondingly, the network device may determine the interval to which the difference value belongs based on the identifier in the first indication information, and determine whether to configure the first frequency band combination for the terminal device based on the interval.

It is assumed that Table 1 shows the correspondence between multiple preset intervals and interval identifiers in the embodiment of the present application. See Table 1, the above multiple preset intervals include {X<-6dB}, {-6dB≤X<-3dB}, {-3dB≤X<0dB}, {0dB≤X<3dB}, {3dB≤X< 6dB}, {X≥6dB}, where the identifier corresponding to the interval {X<-6dB} is "Delta_Refsens_0". The identifier corresponding to the interval {-6dB≤X<-3dB} is "Delta_Refsens_1". The identifier corresponding to the interval {-3dB≤X<0dB} is "Delta_Refsens_2". The identifier corresponding to the interval {0dB≤X<3dB} is "Delta_Refsens_3". The identifier corresponding to the interval {3dB≤X<6dB} is "Delta_Refsens_4". The identifier corresponding to the interval {X≥6dB} is "Delta_Refsens_5".

Table 1

区间标识Interval ID	灵敏度差值Sensitivity difference
Delta_Refsens_0Delta_Refsens_0	X<-6dBX<-6dB
Delta_Refsens_1Delta_Refsens_1	-6dB≤X<-3dB-6dB≤X<-3dB
Delta_Refsens_2Delta_Refsens_2	-3dB≤X<0dB-3dB≤X<0dB
Delta_Refsens_3Delta_Refsens_3	0dB≤X<3dB0dB≤X<3dB
Delta_Refsens_4Delta_Refsens_4	3dB≤X<6dB3dB≤X<6dB
Delta_Refsens_5Delta_Refsens_5	X≥6dBX≥6dB

Therefore, when the above difference is -4dB, the difference belongs to the interval {-6dB≤X<-3dB}, and the corresponding interval identifier is "Delta_Refsens_1", then the terminal device can carry "Delta_Refsens_1" in the first indication information, to indicate the interval in which the difference lies. When the above difference is 4dB, the difference belongs to the interval {3dB≤X<6dB}, and the corresponding interval is identified as "Delta_Refsens_4", then the terminal device can carry "Delta_Refsens_4" in the first indication information to indicate the location of the difference interval.

In some other implementation manners, the terminal device may also determine to send a high sensitivity indication or a low sensitivity indication to the network device based on the above-mentioned magnitude between the actual receiving sensitivity and the sensitivity reference value. For example, when the actual receiving sensitivity is higher than the sensitivity reference value, the terminal device may send first indication information to the network device, the first indication information carrying a high sensitivity indication, at this time, the network device may configure the first frequency band combination for the terminal device. For another example, when the actual receiving sensitivity is lower than the sensitivity reference value, the terminal device may send first indication information to the network device, the first indication information carrying a low sensitivity indication, at this time, the network device may not configure the first frequency band for the terminal device combination.

Of course, in order to reduce the overhead of transmitting the first indication information, the network device can also default the terminal device to be at high sensitivity. When the actual receiving sensitivity is lower than the sensitivity reference value, the terminal device can use the first indication information to instruct the network device to send low sensitivity instruct. Conversely, the network device may default the terminal device to be at low sensitivity, and when the actual receiving sensitivity is higher than the sensitivity reference value, the terminal device may use the first indication information to instruct the network device to send a high sensitivity indication.

Mode 3: The actual interference intensity is represented by the actual receiving sensitivity, and the first preset value may be determined based on the reference sensitivity and the second sensitivity threshold.

As mentioned above, in order to make the solution of the present application compatible with the existing communication protocol, it is desired to use the reference sensitivity corresponding to the frequency band defined in the communication protocol to determine the first preset value. However, in some cases, the above definition of reference sensitivity is not suitable for the solution of the embodiment of the present application. Therefore, in the embodiment of the present application, the reference sensitivity may be adjusted through the second sensitivity threshold.

It should be noted that the foregoing second sensitivity threshold may be preconfigured or predefined. In some implementation manners, the foregoing second sensitivity threshold may be preconfigured by the network device. In some other implementation manners, the foregoing second sensitivity threshold may also be predefined by a protocol.

Assume that the first frequency band combination includes frequency band A and frequency band B. The agreement stipulates that the reference sensitivity S corresponding to frequency band B is -94dB. And the second sensitivity threshold Y configured by the network device for the terminal device is 6 dB. In this case, the first preset value is X=S+Y=-94dB+6dB=-88dB. In the case that frequency band A interferes with frequency band B, the actual receiving sensitivity of the terminal equipment is -90dB. At this time, the difference between the actual receiving sensitivity and the first preset value is -2dB.

It should be noted that the method for the terminal device to report the above-mentioned difference can refer to the introduction in the above method 2, that is, the terminal device can directly report the above-mentioned difference to the network device, and the terminal device can also report the interval to which the above-mentioned difference belongs to the network device , the terminal device may also send the foregoing high-sensitivity indication and/or low-sensitivity indication to the network device. For the sake of brevity, details are not repeated here.

It should also be noted that the above second sensitivity threshold may be a positive value or a negative value, which is not limited in this embodiment of the present application.

Of course, for the setting method of the above-mentioned second sensitivity threshold, refer to the above-mentioned setting method of the level threshold. In some implementation manners, the same second sensitivity threshold may be configured for terminal devices belonging to the same cell. Of course, different second sensitivity thresholds may also be configured for terminal devices belonging to the same cell.

In some other implementation manners, assuming that the terminal device supports multiple frequency band combinations, and the multiple frequency band combinations include the above-mentioned first frequency band combination, at this time, the same second sensitivity threshold may be configured for different frequency band combinations in the multiple frequency band combinations . Of course, different second sensitivity thresholds may also be configured for different frequency band combinations among the multiple frequency band combinations.

In some other implementation manners, it is assumed that the first frequency band combination includes multiple carrier combinations. In order to reduce the complexity of configuring the second sensitivity threshold, the same second sensitivity threshold may be configured for different carrier combinations in multiple carrier combinations. Certainly, different second sensitivity thresholds may also be configured for different carrier combinations among multiple carrier combinations.

As introduced above, in some known solutions, the terminal device sends capability information to the network device to indicate whether the terminal device supports simultaneous sending and receiving capability under the first frequency band combination. Correspondingly, the network device is only in a passive receiving position. No matter what the actual interference intensity of the terminal device is, the network device can only determine whether to configure the simultaneous sending and receiving capability under the first frequency band combination for the terminal device based on the capability information reported by the terminal device. In some cases, even if the actual interference intensity of the terminal device in the first frequency band combination is not high, the terminal device will inform the network device that it does not support the simultaneous sending and receiving capability in the first frequency band combination. At this time, the network device can only avoid Sending data to the terminal device through the first frequency band combination and receiving data sent by the terminal device through the first frequency band combination within the same period of time greatly increases the complexity of network device scheduling.

In order to avoid the above problems, this application also provides a communication method, that is, the network device can configure the first preset value for the terminal device to control the terminal device to judge based on the comparison result between the actual interference intensity and the first preset value Whether to report capability information.

That is to say, the terminal device receives the first configuration information sent by the network device, and the first configuration information is used to configure the first preset value corresponding to the first frequency band combination; the terminal device compares the actual interference intensity under the first frequency band combination with the first The preset value is compared to obtain a comparison result; based on the comparison result, the terminal device determines whether to send the first capability information to the network device, and the first capability information indicates that the terminal device has the ability to transmit and receive simultaneously under the first frequency band combination.

In some implementation manners, when the above comparison result indicates that the actual interference intensity is low, the terminal device may send capability information to the network device to inform the terminal device of its ability to support simultaneous sending and receiving under the first frequency band combination. Correspondingly, the network device can perform scheduling for the terminal device based on the capability information reported by the terminal device. Of course, in some other implementation manners, when the above comparison result indicates that the actual interference intensity is low, the network device may ignore the above capability information, and directly assume that the terminal device supports the simultaneous sending and receiving capability under the first frequency band combination.

In some other implementation manners, when the above comparison result indicates that the actual interference intensity is low, the terminal device may selectively send capability information to the network device to inform the terminal device of its ability to support simultaneous sending and receiving under the first frequency band combination. That is to say, in this case, the terminal device may choose to send the above capability information to the network device, or the terminal device may also choose not to send the above capability information to the network device.

It should be noted that when the actual interference intensity is represented by an actual MSD, the comparison result indicates that the actual interference intensity is relatively low, which can be understood as that the actual MSD is lower than the first preset value. When the actual interference intensity is represented by the actual receiving sensitivity, the comparison result indicates that the actual interference intensity is relatively low, which can be understood as that the actual receiving sensitivity is higher than the first preset value.

In some implementation manners, when the above comparison result indicates that the actual interference intensity is relatively high, the terminal device may not send capability information to the network device. Correspondingly, the network device may perform scheduling for the terminal device based on the fact that the terminal device does not support the simultaneous sending and receiving capability under the first frequency band combination. Of course, in some other implementation manners, when the comparison result indicates that the actual interference intensity is relatively high, the network device may directly assume that the terminal device does not support simultaneous sending and receiving capabilities under the first frequency band combination, regardless of whether the terminal device sends capability information.

In some other implementation manners, when the above comparison result indicates that the actual interference intensity is relatively high, the terminal device may selectively send capability information to the network device to inform the terminal device of its ability to support simultaneous sending and receiving under the first frequency band combination. That is to say, in this case, the terminal device may choose to send the above capability information to the network device, or the terminal device may also choose not to send the above capability information to the network device.

It should be noted that when the actual interference intensity is represented by an actual MSD, the comparison result indicates that the actual interference intensity is relatively high, which can be understood as that the actual MSD is higher than the first preset value. When the actual interference intensity is represented by the actual receiving sensitivity, the comparison result indicates that the actual interference intensity is relatively high, which can be understood as that the actual receiving sensitivity is lower than the first preset value.

In the above-mentioned known technologies, the terminal device will send capability information to the network device to indicate whether to support the simultaneous sending and receiving capability under the first frequency band combination, and the capability information is for multiple frequency bands or multiple frequency bands in the first frequency band combination For each carrier, it will also increase the complexity of network equipment scheduling to a certain extent.

Because in some cases, the interference between the frequency bands is usually caused by the transmitted signal through the frequency band A to the received signal through the frequency band B. If the other way around, transmitting a signal via band B does not interfere with receiving a signal via band A. However, the above capability information is only for the first frequency band combination, so even if the transmission signal is transmitted through the frequency band B, it will not interfere with the signal received through the frequency band A. The network equipment can only schedule the terminal equipment based on the fact that the terminal equipment does not support simultaneous transmission and reception capabilities in the first frequency band, which increases the complexity of network equipment scheduling.

Therefore, in order to avoid the above problems, the terminal device may also send the interference occurrence frequency band and the interfered frequency band in the first frequency band combination to the network device. For example, in the situation shown in FIG. 5 , the terminal device may send to the network device the transmitting frequency band whose interference frequency band is frequency band A, and the interfered frequency band is frequency band B. For another example, in the situation shown in FIG. 6 , the terminal device may send to the network device that the interfering frequency band includes the transmitting frequency band of frequency band A and the frequency band B, and the interfered frequency band is the receiving frequency band of frequency band A.

In some implementation manners, the terminal device may send the interference frequency band and the interfered frequency band through RRC signaling.
