In order to facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following related technologies can be optionally combined with the technical solutions of the embodiments of the present application, and they all belong to the embodiments of the present application. protected range.

signal modulation

In wireless communications, signal modulation is used to move the spectrum of the signal. That is, as shown in Figure 2, the input signal f1 and the modulated carrier f0 are nonlinearly operated through a mixer to generate the sum/difference frequency signal of the two signals, from which The required high-order frequency signal f2 is screened out, as shown in Figure 3, completing the spectrum shift from low frequency to high frequency. The frequency relationship is f2=f1+f0, where f1 is the input low-frequency signal, f2 is the output high-frequency signal, and f0 is the modulated carrier wave.

For a broadband signal, its center frequency point is called the position of the DC (Direct Current, DC) carrier (it can also be called the LO position, that is, the local oscillator frequency position), as shown in f0 in Figure 2.

In actual implementation, as shown in Figure 4, the baseband integrated circuit (Baseband Integrated Circuit, BBIC) outputs the baseband signal, and the baseband signal is input to the radio frequency transceiver, that is, the radio frequency integrated circuit (Radio Frequency Integrated Circuit, RFIC). RFIC is based on The DC carrier, f0, modulates the baseband signal to obtain a radio frequency signal. The radio frequency signal generated by the RFIC is further amplified by the power amplifier (Power Amplifier, PA) and output to the antenna. The antenna radiates the amplified radio frequency signal into the air.

f0 is also called the position of the DC carrier, which is the frequency position of the local oscillator of the terminal device.

Reporting of DC carrier position

As shown in Figure 4, part of the DC carrier wave of the terminal equipment leaks into the transmission link during the signal modulation process, and is amplified by the PA and transmitted into the air. When the DC carrier is located in channel 501 as shown in Figure 5, channel 501 is an interfered channel. The leaked DC carrier is strong and will cause a reduction in the received signal signal-to-noise ratio (SINR) if received by the base station. Therefore, the position of the DC carrier of the terminal device needs to be reported to the base station, and the base station removes the leaked signal according to the specific position of the DC carrier to improve the signal-to-noise ratio of the received signal.

In reporting the location of DC carriers, the reporting is different for different frequency bands:

Frequency Range (FR)1 (frequency band below 7.125GHz) usually refers to), if the position of the DC carrier is within the frequency range of the transmitted signal, the terminal device reports the position of the DC carrier to the base station, and when the DC carrier If the position is not within the frequency range of its transmitted signal, the position of the DC carrier will not be reported;

For FR2 (also known as the millimeter wave band, usually the frequency band above 24GHz), if the position of the DC carrier is within the frequency range of its transmitted signal, or within the frequency range of its received signal, the specific DC carrier position needs to be reported to the base station.

The DC carrier position reporting is to improve the received signal quality of the base station, so as to obtain higher SINR, and then use high-order modulation methods such as 256QAM and 1024QAM. Therefore, after the terminal device determines its own transmitting frequency band or receiving frequency band, considering the improvement of the signal of the terminal device itself, after the position of the DC carrier is located in its own transmitting frequency band or receiving frequency band, it reports the position of the DC carrier to the base station, regardless of Whether it is the base station or the terminal equipment, the impact on other UEs is not considered.

The second terminal device is outside the coverage of the network device and is outside the coverage of the first terminal device. any terminal device.

The target frequency range is a frequency range associated with the first cell where the network device or the first terminal device is located. The target frequency range is used in relation to the first location to determine whether the first terminal device reports the first location. Optionally, the relationship between the target frequency range and the first position indicates that the DC carrier of the first terminal device will interfere with the signal quality of the second terminal device, and the target frequency range indicates that the first position is reported. Optionally, if the relationship between the target frequency range and the first position indicates that the DC carrier of the first terminal device will not interfere with the signal quality of the second terminal device, then the target frequency range indicates not to report the first position.

It can be understood that the target frequency may include a continuous frequency range or multiple discontinuous frequency ranges.

When the network device configures the target frequency range to the first terminal device to instruct the first terminal device to report the location of the DC carrier, it clearly indicates to the first terminal device the frequency range in which the DC carrier may cause interference, so that the first terminal device The first position is reported based on a frequency range that may cause interference, thereby preventing the DC carrier of the first terminal device from interfering with the signal quality of other terminal devices. The network device configures the target frequency range to the first terminal device to instruct the first terminal device not to report the first location, and clearly indicates to the first terminal device the frequency range in which the DC carrier will not cause interference, so that the first terminal device When determining a frequency range that will not cause interference and not reporting the first location, thus ensuring signal quality, the signaling overhead of the first terminal device is reduced.

At this time, when the first terminal device determines that the target frequency range instructs the first terminal device to report the first location and determines that the reporting instruction information is received, the first terminal device reports the first location.

In the embodiment of the present application, the network device configures the target frequency range to the first terminal device to instruct the first terminal device to report or not report the location of the DC carrier, thereby achieving effective reporting of the location of the DC carrier while avoiding the need for receiving signals.

S701. The first terminal device receives the first indication information sent by the network device. The first indication information is used to indicate a target frequency range. The target frequency range is used to instruct the first terminal device to report the first location. The first position is the position of the DC carrier of the first terminal device.

After determining the target frequency range based on the first indication information, the first terminal device determines whether to report the location of the DC carrier based on the target frequency range. Optionally, the first terminal device determines whether to report the location of the DC carrier based on the relationship between the target frequency range and the first location. If the first terminal device determines that the DC carrier of the first terminal device will interfere with the signal quality of the second terminal device based on the relationship between the target frequency range and the first location, it determines to report the first location. If the first terminal device determines based on the relationship between the target frequency range and the first location that the DC carrier of the first terminal device will not interfere with the signal quality of the second terminal device, it determines not to report the first location.

If the first terminal device determines to report the first location, it reports the first location to the network device. If the first terminal device determines not to report the first location, it may not report the first location, or may report the first location based on its own implementation.

The interference frequency range is reported at the first position, thereby preventing the DC carrier of the first terminal device from interfering with the signal quality of other terminal devices. The network device configures the target frequency range to the first terminal device to instruct the first terminal device not to report the first location, and clearly indicates to the first terminal device the frequency range in which the DC carrier will not cause interference, so that the first terminal device When determining a frequency range that will not cause interference and not reporting the first location, thus ensuring signal quality, the signaling overhead of the first terminal device is reduced.

For the first frequency range, the first frequency range is a frequency range that may be used by the second terminal device. When the first position is located in the first frequency range and the DC carrier of the first terminal device interferes with the signal quality of the second terminal device, the first frequency range instructs the first terminal device to report the first position. When the first position is outside the first frequency range and the DC carrier of the first terminal device will not interfere with the signal quality of the second terminal device, the first frequency range instructs the first terminal device not to report the first position.

As shown in Figure 12, the first terminal device 1201 communicates with the network device 1202-1. The network 1203 of the network device is the first network that the first terminal device 1201 accesses. The network device under the network 1203 may also include a network device. Device 1202-2.

In some embodiments, the second frequency range includes:

The fourth range is the bandwidth of a second network, the second network is different from the first network, and the first network is a network to which the first terminal device is accessed.

The second network and the first network are different networks, where the second network may include: a network of the second operator and a network of the first operator other than the first network.

It can be understood that there is no overlap between the bandwidth of the first network and the bandwidth of the second network.

In an example, as shown in Figure 13, the bandwidth of the first network is bandwidth 1301, and the bandwidth of the second network includes bandwidth 1302. When the position of the DC carrier of the first terminal device is frequency 1303, the bandwidth 1301 indicates that the first terminal device reports the position of the DC carrier. When the position of the DC carrier of the first terminal device is frequency 1304, the bandwidth 1302 indicates that the first terminal device does not report the position of the DC carrier.

In some embodiments, the second network differs from the first network in at least one of the following parameters:

Mobile Country Code (MCC), Mobile Network Code (MNC), network standard.

In some embodiments, the first indication information includes at least one of the following information:

First configuration information, the first configuration information is used to indicate the offset of the target frequency range relative to the reference frequency point;

Second configuration information, the second configuration information is used to indicate a target frequency band, and the target frequency range is the frequency range of the target frequency band.

For the first configuration information, the offset between the target frequency range and the reference frequency point is indicated.

When receiving the offset, the first terminal device determines the target frequency range based on the offset and the reference frequency point.

In the case where the target frequency range includes a continuous frequency range, the offset indicated by the first configuration information includes offsets of the lowest frequency and the highest frequency of the target frequency range relative to the reference frequency point. In an example, as shown in Figure 14, the target frequency range is: f11 to f12, then the offset indicated by the first configuration information includes: the offset 1 of f11 relative to the reference frequency point f10, and the offset 1 of f12 relative to the reference frequency point. Offset 2 of point f10.

In the case where the target frequency range includes multiple discontinuous frequency ranges, among the offsets indicated by the first configuration information, one frequency range corresponds to two offsets. In an example, as shown in Figure 15, the target frequency range is: f11 to f12, f21 to f22, then the offset indicated by the first configuration information includes: the offset corresponding to f11 to f12: f11 relative to the reference frequency point The offset of f10 is 1, the offset of f12 is 2 relative to the reference frequency point f10, and the corresponding offsets from f21 to f22 are: the offset 3 of f21 relative to the reference frequency point f10, and the offset 4 of f22 relative to the reference frequency point f10.

In some embodiments, the first configuration information includes: a first value used to determine the offset from a reference frequency interval.

Here, when the network device determines the first configuration information, it determines the first value based on the offset and the reference frequency interval, where the first configuration information may indicate multiple first values to determine multiple offsets from the reference frequency interval. After receiving the first value, the first terminal device determines the offset interval corresponding to the first value based on the first value and the reference frequency interval, thereby allowing the first terminal device to determine the target frequency range based on the determined offset and the reference frequency point.

It can be understood that when there is a frequency smaller than the reference frequency point in the target frequency range, the first value corresponding to the frequency smaller than the reference frequency point is a negative number smaller than 0, indicating that the frequency is smaller than the reference frequency point, and the offset corresponding to the frequency is Negative; for a frequency in the target frequency range that is greater than the reference frequency point, the first value corresponding to the frequency greater than the reference frequency point is a positive number greater than 0, indicating that the frequency is greater than the reference frequency point, and the offset corresponding to the frequency is positive.

In an example, the reference frequency interval is 10 kHz, and the first configuration information indicates the following first value: 10 to 15. Then the offset is 100kHz to 150kHz. At this time, the target frequency range is the frequency range from 100kHz to 150kHz from the reference frequency point.

In an example, the reference frequency interval is 20 kHz, and the first configuration information indicates the following first values: -5 to -1, 10 to 15. The offset is -100kHz to -20kHz, and 200kHz to 300kHz. At this time, the target frequency range includes: the frequency range from -100kHz to -20kHz from the reference frequency point and the frequency range from 200kHz to 3 00kHz from the reference frequency point.

optionally. The first value may be identified by bits.

In some embodiments, the reference frequency interval is a subcarrier interval or a preset frequency interval.

Optionally, the subcarrier spacing is 15kHz.

The preset frequency interval is a frequency interval negotiated between the first terminal device and the network device and used to determine the offset in combination with the first value. Optionally, the preset frequency intervals are 5khz, 10kHz, 15kHz, etc.

In some embodiments, the reference frequency point is one of the following:

Frequency points specified in the agreement;

Default frequency point;

The frequency point indicated by the network device to the first terminal device.

The frequency specified by the protocol is a set fixed frequency, for example: 100MHz.

The preset frequency point is the frequency point negotiated between the first terminal device and the network device. It can be a specific frequency point, such as 100MHz, 200MHz, or a frequency point related to the configuration of the first terminal device, such as a reference frequency. The point is the lowest frequency of the transmission bandwidth of the first terminal device.

When the reference frequency point is a frequency point indicated by the network device to the first terminal device, the network device indicates the reference frequency point to the first network device, and the first terminal device determines the reference frequency point based on the instruction of the network device.

For the second configuration information, the second configuration information indicates one frequency band, that is, the target frequency band. When the first network device receives the second configuration information, it determines the frequency range of the target frequency band indicated by the second configuration information as the target frequency range.

Optionally, the network device may determine the target frequency band based on one or more of the first range, the second range, the third range and the fourth range. At this time, the target frequency band may include the first range, the second range, the third range. range and one or more of the fourth range.

In an example, if the first range is 2570MHz to 2595Mhz, then the target frequency band is: 2570MHz to 2620MHz, where 2570MHz to 2620MHz is the frequency band in which the first range is located among the plurality of frequency bands.

In an example, the third range is 2570MHz to 2595Mhz, and the target frequency band is: 2550MHz to 2650MHz, where 2550MHz to 2650MHz is the frequency band where the first range among the plurality of frequency bands is located.

In the case where the first indication information includes the second configuration information, the first terminal device determines the target frequency band based on the second configuration information, but the first terminal device does not know the first range, the second range, the third range or the fourth range.

In some embodiments, the second configuration information includes: a second value, and the spectrum segment corresponding to the second value is the target frequency band.

Here, the second value is the identifier of the target frequency band among the set multiple spectrum segments, where different spectrum segments correspond to different values.

In an example, the second value is 38, the first frequency band is frequency band 38, and the target frequency range is the frequency range of frequency band 38: 2570 MHz to 2620 MHz.

In an example, the second value is 20, and the first frequency band is the 20th frequency band among the 100 divided frequency bands. At this time, the size of one frequency band can be customized.

In some embodiments, the spectrum segmentation method is a frequency band division method stipulated in the protocol or a customized division method based on fixed frequency band intervals.

The predefined frequency band division method can be a universal frequency band division method, for example: the frequency range of frequency band 34 is 2120MHz to 2125MHz, the frequency range of frequency band 38 is 2570MHz to 2620MHz, the frequency range of frequency band 39 is 1880MHz to 1920MHz, and the frequency range of frequency band 40 The frequency range is 2300MHz to 2400MHz.

The custom division method based on fixed frequency intervals is a custom frequency band division method, and the sizes of different frequency bands are the same, which is a fixed frequency interval. In one example, the fixed frequency spacing is 100MHz. In one example, the fixed frequency spacing is 50MHz.

In some implementations, the second bandwidth is located within or outside the target frequency band, and the second bandwidth is the bandwidth of the first terminal device.

In some embodiments, the first indication information includes third configuration information, the third configuration information is used to indicate the third range or the fourth range, and the third configuration information includes at least one of the following :

Start frequency and stop frequency;

Absolute Radio Frequency Channel Number (ARFCN).

Here, the third configuration information is used to indicate the third range, that is, the frequency range of the first network or the fourth range, that is, the frequency range of the second network. Both the third range and the fourth range may be indicated by third configuration information. The third configuration information indicating the third range and the third configuration information indicating the fourth range have different values.

When the third configuration information includes the starting frequency and the ending highest frequency, it directly indicates the third range or the fifth range.

In the case of the third configuration information, ARFCN, the frequency range corresponding to ARFCN is the third range or the fourth range.

It is understandable that ARFCN is a channel number defined for channel division, ranging from 0MHz to 3GHz in 5khz steps, and from 3GHz to 24.25GHz in 15khz steps. When the channel number is determined, the corresponding frequency range is clear.

In some embodiments, the network device also performs the following steps:

The network device receives third information sent by the first terminal device; the third information is used to request the third configuration information.

At this time, the terminal device also performs the following steps: the first terminal device sends second indication information to the network device; the second indication information is used to request the third configuration information.

As shown in Figure 16, it includes:

S1601. The first terminal device sends second instruction information to the network device.

S1602. The network device sends the third configuration information to the first terminal device.

In the embodiment of the present application, the first terminal device may determine whether it has a priori information of the fifth range, and if it does not have a priori information of the fifth range, send the second indication information to the network device to request the instruction of the fifth range. The third configuration information of the five ranges.

In some embodiments, S601, the network device sends the first instruction information to the first terminal device, including: the network device sends the first instruction information to the first terminal device through a Radio Resource Control (Radio Resource Control, RRC) message. the first instruction information.

Optionally, the RRC message includes: RRC reconfiguration message.

Next, the wireless communication method provided by the embodiment of the present application will be further described.

In the wireless communication method provided by the embodiment of the present application, the base station informs the terminal that the DC position needs to be reported or not reported when the DC falls within which frequency range, such as the base station bandwidth, etc., and describes whether the terminal device needs to report or does not need to report. frequency range indication.

In the reporting of the position of the DC carrier in the related art, when the position of the DC carrier of the terminal device is outside the range of its own carrier, it will not be reported.

For UE1, the position of the DC carrier only needs to be reported when the position of the DC carrier is located in its transmitting frequency range (FR1) or transmitting + receiving frequency range (FR2). As shown in Figure 17, when the position of the DC carrier is When the location falls outside the frequency range of UE1 (for FR1, it refers to the transmission frequency range of UE1, and for FR2, it refers to the transmission and reception frequency range of UE1), the location of the DC carrier will not be reported to the network.

For a base station, as shown in Figure 18, there will be multiple terminals under a base station that are transmitting at the same time and occupy different frequency domain resources. As shown in Figure 19, when the position of the DC carrier of UE1 falls into the transmission frequency range of UE2, it makes it difficult for the base station to demodulate the signal transmitted by UE2. Therefore, the DC carrier of UE1 will cause interference to the uplink signal of UE2 and reduce the SINR. . Under the existing mechanism, this interference cannot be eliminated because the base station does not know the location of the DC carrier of UE1. Therefore, for the above scenario where the DC carrier of UE1 falls within the range of the uplink transmission signals of other UEs, it is necessary to consider how to enhance it.

A direct processing method is to report the DC position when the position of the DC carrier is outside the occupied spectrum. However, the problem with this processing method is that it does not specify the specific spectrum range and relies entirely on air interface signaling to report a large range. The location of the DC carrier within the network not only brings a great burden to air interface signaling, but is also unnecessary. Therefore, a more flexible processing method is for the base station to inform the terminal whether the DC position needs to be reported or not reported when the DC falls within which spectrum range. This spectrum range can be determined by the base station.

In the wireless communication method provided by the embodiment of this application, the base station configures the spectrum range that needs to be reported or does not need to be reported to the terminal device, so that the UE can learn the location of the DC carrier that is reported or not reported, thereby preventing the location of the DC carrier of UE1 from falling into other UE2 within the transmission spectrum range, and can prevent the terminal equipment from reporting the location of a worthless DC carrier when the DC of UE1 falls into the spectrum range of a non-this base station or this operator.

Next, in order to more clearly understand the wireless communication method provided by the embodiment of the present application, in Figure 20, the uplink bandwidth used by the base station, the uplink bandwidth of the cell, and the transmission bandwidth of the UE are explained to illustrate the scenario where DC interference occurs.

As shown in Figure 20, the NR uplink bandwidth (such as 400MHz bandwidth) used by the base station to work is the range of uplink signals that the base station needs to receive in the current area, and these signals can come from multiple NR cells.

As shown in Figure 20, each NR cell has its supported uplink bandwidth (such as 100MHz bandwidth), and this cell bandwidth is used to serve multiple UEs.

As shown in Figure 20, each UE can occupy part of the cell bandwidth for uplink signal transmission. When DC falls outside the UE transmission bandwidth and is included in the NR uplink bandwidth of the current cell, or is included in the NR bandwidth of the current base station, uplink interference will be caused.

For the scenario shown in Figure 20 above where DC interference may occur, the base station may require the UE to report the location of its DC carrier. The base station can determine the interfered spectrum range in the following ways:

Method 1: Determine based on the NR bandwidth of the current base station operation and the UE transmission bandwidth.

As shown in Figure 21, the NR bandwidth of the base station is divided based on the transmission bandwidth of the UE into: area 2101, area 2102 and the area 2103 corresponding to the transmission bandwidth of the UE. The bandwidth corresponding to area 2101 is the NR bandwidth of the base station that is lower than that of the UE. Partial bandwidth of the transmission bandwidth, the bandwidth corresponding to area 2102 is the part of the NR bandwidth of the base station that is higher than the transmission bandwidth of the UE. Within the NR bandwidth of the current base station, UE1 only occupies part of the spectrum in area 2103 for transmission. Then when the DC carrier falls into area 2101 and area 2102 as shown in the figure, the UE's DC carrier will be uplinked to the UEs in these areas. The transmission causes interference. At this time, the position of the DC carrier needs to be reported to the base station, so that the base station can improve the signal-to-noise ratio of the received signal by eliminating the DC carrier. Then the frequency range corresponding to area 2101 and area 2102 is the frequency range that DC needs to report. .

Method 2: Determine based on the cell uplink frequency range and UE transmission bandwidth.

As shown in Figure 22, the uplink frequency range of the cell is divided into area 2201, area 2202 and the area 2203 corresponding to the UE's transmission bandwidth based on the UE's transmission bandwidth. The bandwidth corresponding to area 2201 is the transmission lower than that of the UE in the uplink frequency range of the cell. Part of the bandwidth, the bandwidth corresponding to area 2202 is the part of the bandwidth in the uplink frequency range of the cell that is higher than the transmission bandwidth of the UE. Within the uplink frequency range of the cell (100MHz as an example), UE1 only occupies part of the spectrum in area 2203 (for example, uplink BWP = 20MHz) for transmission. At this time, in the remaining spectrum range (area 22011 and area 2202), the base station Other UEs in the same cell can be scheduled for uplink transmission. Then when the DC carrier of UE1 falls into the illustrated area 2201 and area 2202, the UE's DC carrier will cause interference to the UE's uplink transmission in these areas. At this time, it is necessary to The position of the DC carrier is reported to the base station, so that the base station can improve the signal-to-noise ratio of the received signal by eliminating the DC carrier. Then the frequency range corresponding to area 2201 and area 2202 is the frequency range that DC needs to be reported.

The base station also determines the scope of the interfered spectrum by:

Method 3. The location of the terminal's DC carrier is valuable and meaningful only if it is reported to the base station of the current network, because if the DC is located on the spectrum of another operator's network or a network of other network standards of the current operator, then the terminal's DC does not It will not affect the current serving base station, and the location information received by the current base station from this DC carrier cannot be used. Therefore, as shown in Figure 23, when the DC carrier is located in the frequency range of the network that the current terminal device is connected to, it is reported. When it is located in the frequency range of other networks, there is no need to report. Usually, which network a cell belongs to is judged by MCC, MNC, and network format.

In the embodiment of this application, the frequency range indication that the location of the DC carrier needs or does not need to be reported can be implemented in the following ways:

Indication method 1. Based on a certain reference frequency point, indicate the frequency interval from the reference frequency point.

Based on the frequency range that needs to be reported as shown in Figure 21, as shown in Figure 24, the base station uses the reference frequency point F0 as a reference (F0 can be an agreed/predefined frequency point, such as the lowest starting frequency of the frequency band, or A certain frequency point indicated by the base station, etc.), the frequency interval or offset of the area 2101 relative to the reference frequency point F0 may be Dis_1 to Dis_2, and the offset of the area 2102 relative to the reference frequency point F0 may be Dis_3 to Dis_4.

The frequency interval can be indicated by the step size, that is, the reference frequency interval. The step size can be the size of the subcarrier, 15khz, or the agreed frequency interval, such as 5khz. The frequency range that needs to be reported or the frequency range that does not need to be reported can be indicated by the number of steps between the base station indication and the reference frequency point F0.

Taking Dis_1 to Dis_2 of the indication area 2101 shown in Figure 24 that need to be reported based on the frequency interval indication as an example, for the area 2101, Dis_1 is 150khz; Dis_2 is 300khz. Then when taking 15khz as the step size, the frequency range of area 2101 is a frequency interval of 10 to 20 steps. The terminal can indicate the number of steps in the form of bit instructions.

Indication method 2: Indication frequency band

In order to simplify the indication of the DC reporting range, the indication can be based on a certain set spectrum range, such as the frequency band. At this time, the base station instructs the terminal that the spectrum range that needs to be reported or not required to be reported is a certain frequency band. Then as long as the DC of the terminal is within the frequency band, DC reporting is required or DC reporting is not required. When the frequency band indicated by the base station is the frequency range that needs to be reported, as shown in Figure 25, the transmission bandwidth of the terminal may be located within the frequency band, as shown in Figure 26, or may not be located within the frequency band.

Instruction method 3: Indicate auxiliary instruction information

When a terminal accesses a cell, it also knows which network the current cell belongs to or does not belong to.

For the network to which the terminal is connected, if the terminal has a priori information about the spectrum of the network, then the DC location does not need to be reported when the DC is located in a spectrum that does not belong to this network. Of course, when the DC is located in a spectrum that does not belong to this network, whether to report the location of the DC carrier may be decided by the UE independently or may be instructed by the network. If the terminal does not have a priori information about the spectrum of the network, it needs auxiliary indication information from the base station. The auxiliary indication information can clarify the spectrum to which the network belongs (such as LTE spectrum and/or NR spectrum). The specific indication method may be, for example, indicating the spectrum range in MHz units, or indicating the absolute radio frequency channel number (Absolute Radio Frequency Channel Number, ARFCN) range. Among them, ARFCN is a channel number defined by NR in order to unify the division of channels, ranging from 0MHz to 3GHz in 5khz steps, and from 3GHz to 24.25GHz in 15khz steps. As long as the channel number is clear, the corresponding channel will be clear, and the frequency range used by the network will also be determined.

In practical applications, in addition to the above-mentioned determination of whether to require the UE to report the location of the DC carrier based on the base station, cell/carrier, and operator spectrum range, the modulation method used by the interfered UE to transmit signals can also be further considered. Only when the modulation method is For example, only when high-order modulation such as 64QAM or 256QAM or 1024QAM or 2048QAM is used, the DC carrier of UE1 will interfere with the uplink signal of UE2, causing problems with the uplink demodulation of the base station. Only then will the UE be required to report the DC position.

In this embodiment of the present application, the base station's indication of whether to report DC carriers within the indicated frequency range may be an indication that the UE is required to report, or it may be an indication that the UE is not required to report. The instruction information reported by the base station to the DC can be sent to the terminal through an RRC message such as an RRC reconfiguration message. After receiving the spectrum range information reported by the DC, the terminal can report or not report the DC carrier position accordingly.
