Detailed ways

In order to make the purpose, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

The network architecture and business scenarios described in the embodiments of this application are to more clearly explain the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided by the embodiments of this application. Those of ordinary skill in the art will know that with the network architecture evolution and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

Receiver sensitivity rollback means that the terminal's receiver is affected by factors such as interference or noise, resulting in a certain deterioration in receiver sensitivity. There are many situations that cause sensitivity rollback in New Radio (NR). The more typical ones are the dual connection architecture (EUTRA-NR Dual Connection, EN-DC) where EUTRA is the main one and NR is the supplement. EUTRA is the main one and EUTRA is the main one. Under the auxiliary dual connectivity architecture (NR-EUTRA Dual Connection, NE-DC), dual link (Dual-connectivity, DC) or inter-band carrier aggregation (Carrier Aggregation, CA), harmonic interference or intermodulation interference causes Sensitivity fallback. Let's take EN-DC as an example for a brief introduction.

Usually, the mutual interference within the terminal mainly comes from the nonlinearity of radio frequency front-end devices such as power amplifier (Power Amplifier, PA). When the input signal is a single tone signal cos(wt), the output signal contains high-order harmonic components such as 2wt and 3wt. If harmonics fall into the receiving frequency band, harmonic interference is caused. This harmonic interference often occurs in scenarios where low-frequency transmission and high-frequency reception are performed simultaneously.

When the input signal contains multiple frequency components, the output signal contains various order intermodulation products of these frequency components. For example, if the input signal includes two frequency components cos(w ₁ t) and cos(w ₂ t), the output signal will include second-order intermodulation (w ₁ ±w ₂ ), third-order intermodulation (2w ₁ ±w ₂ ,w ₁ ±2w ₂ ), etc. If the intermodulation signal falls into the receiving frequency band, it will cause intermodulation interference. This intermodulation interference mostly occurs in scenarios where high and low frequencies are transmitted simultaneously, and scenarios where external signals are poured back into the terminal's transmission link.

Take the interference between B3 and n77 as an example, as shown in Figure 1. The second harmonic in the uplink of B3 will cause 2nd harmonic interference in the downlink of n77. The second-order intermodulation signals between B3 uplink and n77 uplink will cause intermodulation interference to B3's downlink reception.

In NR, the above-mentioned harmonic interference and intermodulation interference have a serious impact on the receiving performance of the terminal. In particular, the impact of the second harmonic and second-order intermodulation signal is more likely to reach tens of dB, resulting in sensitivity deterioration of the terminal. The downlink reception coverage has shrunk significantly, as shown in Figure 2. In communication standards, sensitivity rollback is usually defined to be compatible with different interferences, that is, Maximum Sensitivity Degradation (MSD), which represents the downlink reception capability of the terminal allowed by the communication standard for frequency band combinations with interference. deterioration value.

The simultaneous transmission and reception capability of a frequency band combination refers to whether frequency band B can be in the receiving state at the same time when frequency band A transmits for a frequency band combination: frequency band A + frequency band B. Typical scenarios are shown in Figures 3 and 4. Figure 3 shows that when the uplink harmonics of frequency band A affect the downlink reception of frequency band B, the reception performance is seriously degraded. At this time, it may not be possible to support simultaneous transmission and reception capabilities of frequency band A and frequency band B. Figure 4 shows that when frequency band A and frequency band B are in the transmitting state at the same time, the intermodulation signals generated by these two frequency bands fall into the receiving frequency band of frequency band A, causing the receiving performance of frequency band A to seriously degrade. At this time, it may not be possible to support simultaneous transmission and reception capabilities of frequency band A and frequency band B.

In addition to the scenarios shown in Figures 3 and 4, there are other scenarios such as leakage interference of one frequency band to another frequency band caused by too small frequency band spacing, etc., which will cause two frequency bands in a frequency band combination to be unable to transmit and receive at the same time.

Although in related technologies, MSD is defined for frequency band combinations with harmonics and intermodulation interference (such as Long-Term Evolution (LTE) B3+NR n77) to allow terminals to perform certain sensitivity rollbacks. As long as the sensitivity degradation value of the terminal is less than the MSD, it is considered to meet the requirements. But for some frequency band combinations, the MSD value is relatively large. For example, in Figure 1, when second harmonic interference or second-order intermodulation interference occurs, the MSD usually can reach 20dB or more. For this frequency band combination, even if the terminal meets the MSD index, it cannot be effectively utilized in the existing network. Because the base station cannot know the actual sensitivity rollback value of the terminal, it can only estimate the interference situation of each terminal in the cell under this frequency band combination based on the MSD defined in the relevant technology. In the worst case scenario, network equipment does not use this band combination at all because the interference is too severe.

When there is interference such as harmonics and intermodulation in the frequency band combination, it will cause a relatively large sensitivity rollback, making it difficult to effectively utilize the frequency band combination in the existing network. In the following embodiments, the EN-DC combination LTE B3+NR n77 is still used as an example for explanation. For harmonic interference, as mentioned above, the resulting scenario is that B3 transmits in the frequency band combination, and at the same time another frequency band n77 receives, and the harmonic signal of the low-frequency band B3 falls into the receiving frequency range of the high-frequency band n77, thus causing the high-frequency band The receiving sensitivity of n77 deteriorated. As for the intermodulation signal, the intermodulation signal generated by the simultaneous transmission of B3 and n77 in the frequency band combination falls into the receiving frequency range of the frequency band combination.

It is worth noting that no matter harmonic interference, intermodulation interference or leakage interference, etc., it is the interference signal generated by the transmission of this frequency band combination (single transmission or two frequency bands concurrently) that interferes with the received signal, that is, only when this Frequency band combinations only exist when transmitting and receiving simultaneously. And when this frequency band combination is transmitting at the same time, or receiving at the same time, then there is no interference problem for this frequency band combination.

Therefore, how to avoid interference from the terminal can be considered from the time dimension. Based on the actual interference conditions of different terminals, it is decided whether to configure simultaneous transmission and reception between the two frequency bands for the terminal.

Figure 5 shows a block diagram of a communication system provided by an exemplary embodiment of the present application. The communication system includes: a network device 12, a first terminal 14 and a second terminal 16.

The direction in which the network device 12 sends data to the first terminal 14 or the second terminal 16 is downlink or forward, and the carrier used to carry downlink data is called a downlink carrier or forward carrier. The direction in which the first terminal 14 or the second terminal 16 sends data to the network device 12 is uplink or backward, and the carrier used to carry the uplink data is called an uplink carrier or a backward carrier.

In Frequency Division Duplex (FDD) mode, the downlink carrier and the uplink carrier occupy different frequencies respectively and can be considered as two different carriers. For example, within the same frequency band, different bandwidths are divided into downlink carriers and uplink carriers. In Time-Division Duplex (TDD) mode, the downlink carrier and the uplink carrier can be the same carrier. There are both uplink time units and downlink time units in different time units on the same carrier. The same time unit is Upstream time unit or downstream time unit.

The first terminal 14 and the second terminal 16 communicate through sidelink carriers. Sidelink carriers can support FDD or TDD. Normally, for a single terminal, the sidelink carrier is in TDD mode. However, in some scenarios, such as Carrier Aggregation (CA), sidelink carriers may also use FDD mode.

Among them, the first terminal 14/second terminal 16 and the network device 12 can communicate based on a frequency band combination or a carrier combination or a bandwidth combination or a bandwidth part (Band Width Part, BWP). The first terminal 14 and the second terminal 16 Communication can be carried out based on frequency band combination or carrier combination or bandwidth combination or BWP.

Those skilled in the art can understand that from the perspective of network equipment, the three words "send, downlink, and forward" in this article have the same or similar meanings; the words "receive, uplink, and backward" have the same meaning. The meanings of the three words are the same or similar; from the perspective of the first terminal/second terminal, the meanings of the three words "send, uplink, and forward" in this article are the same or similar; " The three words "receiving, downward and backward" have the same or similar meanings.

Figure 6 shows a flow chart of an interference solution method within a frequency band combination provided by an exemplary embodiment of the present application. The method can be executed by the first terminal, and the method includes:

Step 602: The first terminal receives configuration information of the first frequency band and/or the second frequency band. The configuration information is used to configure transmission attributes of the first frequency band and/or the second frequency band in at least one time unit. The transmission attributes include sending and/or take over.

The first terminal uses the frequency band combination to perform uplink and downlink communications with the network device. Alternatively, the first terminal uses the frequency band combination to perform sidelink communication with the second terminal. The frequency band combination includes at least two frequency bands. Illustratively, the frequency band combination includes a first frequency band and a second frequency band, as shown in Figure 7.

In some embodiments, the first terminal receives configuration information of the first frequency band and/or the second frequency band sent by the network device, and the configuration information is used to configure transmission attributes of the first frequency band and/or the second frequency band within at least one time unit. . The time unit includes: at least one of a radio frame, a subframe, a time slot, a symbol, and a symbol group. In order to simplify the description, the following examples mainly take the time unit as a time slot. The uplink time slot refers to the time slot when the first terminal sends uplink signaling and/or uplink data to the network device. The downlink time slot refers to the time slot when the network device sends downlink signaling and/or downlink data to the first terminal or the second terminal. gap. Since time units may appear periodically, the at least one time unit may be multiple time units within a cycle, such as 10 time slots. In the case where at least one time unit is multiple time units within a cycle, the configuration information may be implicitly applicable to all cycles.

In different embodiments, the first frequency band can be understood as: at least one of frequency band, carrier, uplink carrier, downlink carrier, FDD frequency band or carrier, TDD frequency band or carrier, bandwidth, and BWP. The second frequency band can be understood as: at least one of frequency band, carrier, uplink carrier, downlink carrier, FDD frequency band or carrier, TDD frequency band or carrier, bandwidth, and BWP.

In the scenario of uplink and downlink communication, the configuration of the transmission attributes can be understood as: uplink and/or downlink configuration, sending time unit and/or receiving time unit configuration, uplink time unit and/or downlink time unit configuration, uplink time slot and /or at least one of the downlink time slot configurations. From the perspective of the first terminal, the "sending" means that the first terminal sends uplink signaling and/or uplink data to the network device; the "receiving" means that the first terminal receives the downlink signaling and/or downlink data sent by the network device. data.

In some embodiments, the first terminal receives the configuration information of the first frequency band and/or the second frequency band sent by the second terminal, and the configuration information is used to configure the transmission of the first frequency band and/or the second frequency band within at least one time unit. Attributes.

In the scenario of sideline communication, the configuration of the transmission attribute can be understood as at least one of: sending time unit and/or receiving time unit configuration, sending time slot and/or receiving time slot configuration. The "sending" means that the first terminal sends sideline signaling and/or sideline data to the second terminal, and the "receiving" means that the first terminal receives the sideline signaling and/or sideline data sent by the second terminal. .

In some embodiments, the same time unit has a transmission attribute in both sending and receiving. For example, the same time slot is either an uplink time slot or a downlink time slot.

In some embodiments, the transmission attribute includes at least one of sending, restricting sending, receiving, and restricting receiving. The same time unit has one of the transmission attributes of sending, restricted sending, receiving, and restricted receiving. Among them, restricted sending means that sending is not allowed or prohibited, but the time unit can be used for receiving, or cannot be used for receiving; restricted reception means that receiving is not allowed or prohibited, but the time unit can be used for sending, or Not available for sending.

In some embodiments, the configuration information of the first frequency band is used to configure the transmission attributes of the first frequency band in at least one time unit; the configuration information of the second frequency band is used to configure the transmission attributes of the second frequency band in at least one time unit; the first The configuration information of the frequency band and the second frequency band is used to configure transmission attributes of the first frequency band and the second frequency band in at least one time unit.

In some embodiments, the configuration information is used to stagger the sending time unit and the receiving time unit in the first frequency band and the second frequency band where interference may occur (possibly) in the time domain.

For harmonic interference:

The configuration information is used to stagger the sending time unit on the first frequency band and the receiving time unit on the second frequency band, or the configuration information is used to stagger the receiving time unit on the first frequency band and the sending time unit on the second frequency band. . That is, the sending time unit and the receiving time unit will not appear in the first frequency band and the second frequency band at the same time. Since harmonic interference occurs when the transmit signal in one frequency band interferes with the received signal in another frequency band, harmonic interference can be avoided by the occurrence of the transmit time unit and the receive time unit when the two frequency bands are different.

As shown schematically in Figure 8, assuming that within the first time unit, the transmitted signal in the first frequency band will cause harmonic interference to the received signal in the second frequency band, then the configuration information is used to perform at least one of the following configurations:

·Configuring the first time unit in the first frequency band from the transmission time unit to the time unit of restricted transmission;

·Or, change the first time unit in the first frequency band from the sending time unit to the receiving time unit;

·Or, change the first time unit in the second frequency band from the receiving time unit to the sending time unit;

· Alternatively, configure the first time unit in the second frequency band from the reception time unit to the time unit of restricted reception.

That is, the configuration information ensures that within the first time unit, the transmission signal of the first frequency band and the reception signal of the second frequency band will not appear at the same time.

For intermodulation interference:

Assume that the first frequency band includes a transmitting carrier and a receiving carrier, and the configuration information is used to stagger the transmitting time unit on the first frequency band and the transmitting time unit on the second frequency band, or the configuration information is used to stagger the receiving time on the first frequency band. The transmission time unit on the first frequency band and the second frequency band are staggered with the transmission time unit on the second frequency band, or the configuration information is used to combine the transmission time unit that appears on the first frequency band and the second frequency band at the same time and the transmission time unit on the second frequency band, a total of two transmission time units, Stagger the reception time unit on the first frequency band. Since intermodulation interference is the intermodulation signal between the transmitted signal on the first frequency band and the transmitted signal on the second frequency band, which interferes with the received signal on the first frequency band, when the transmission time unit of the first frequency band, the Intermodulation interference can be avoided if the receiving time unit and the transmitting time unit of the second frequency band do not appear at the same time.

As shown schematically in Figure 9, assuming that in the second time unit, the intermodulation signal of the transmit signal on the first frequency band and the second frequency band interferes with the received signal on the first frequency band, then the configuration information is used as follows At least one of the configurations:

·Configure the second time unit in the first frequency band as the time unit for restricted transmission;

·Or, change the second time unit in the first frequency band from the sending time unit to the receiving time unit;

·Or, change the second time unit in the first frequency band from the reception time unit to the reception-restricted time unit;

·Or, change the second time unit in the first frequency band from the receiving time unit to the transmitting time unit;

·Or, configure the second time unit in the second frequency band from the transmission time unit to the time unit of restricted transmission;

·Or, configure the second time unit in the second frequency band from the sending time unit to the receiving time unit.

However, it should be noted that the above examples do not exhaust all configuration possibilities. In the second time unit, it is ensured that the sending time unit of the first frequency band, the receiving time unit of the first frequency band and the sending time unit of the second frequency band are not synchronized. Under the premise that the above-mentioned intermodulation interference problems can be solved, all possible configuration scenarios can be solved. For example, both the transmission time unit of the first frequency band and the transmission time unit of the second frequency band are configured as time units for restricted transmission.

In some embodiments, after receiving the above configuration information, the first terminal enables or enables or activates the configuration information by default; in some embodiments, after receiving the above configuration information, the first terminal also needs to In the case of an activation indication, the configuration information is then enabled or enabled or activated; in some embodiments, after receiving the above configuration information, the first terminal also needs to detect that interference occurs (or the interference level reaches Trigger condition), then enable or enable or activate the configuration information.

To sum up, the method provided by this embodiment configures or reconfigures the transmission/reception attributes of the first frequency band and/or the second frequency band in at least one time unit, so that the first frequency band and the second frequency band can transmit data at the same time. There will be no interference between the transmitted signal and the received signal within the unit, or in other words, the transmitting time unit and the receiving time unit that may interfere with each other in the first frequency band and the second frequency band are staggered in the time domain dimension, thereby avoiding the first frequency band and the third frequency band. Harmonic interference or intermodulation interference occurs between the two frequency bands.

In some embodiments, the above configuration information is sent to the first terminal actively or autonomously by the network device/second device; in some embodiments, the above configuration information is triggered by the first terminal to the network device/second device Or sent by the network device/second device to the first terminal after request.

Figure 10 shows a flow chart of an interference solution method within a frequency band combination provided by another exemplary embodiment of the present application. The method may be executed by the first terminal, and the method includes:

Step 601: The first terminal sends interference indication information;

When detecting interference between the first frequency band and the second frequency band, the first terminal sends interference indication information to the network device/second device.

The interference relief information is used to indicate interference relief between the first frequency band and the second frequency band, and/or the type of interference relief between the first frequency band and the second frequency band. In some embodiments, the interference type to be relieved is an optional content of the interference indication information.

The interference types to be removed include: at least one of harmonic interference and intermodulation interference.

Step 604: The first terminal receives instruction information, which is used to deactivate or release or cancel or release the above configuration information.

In the uplink and downlink communication scenarios, the first terminal receives the instruction information from the network device, which is sent by the network device based on the interference relief information; in the sidelink communication scenario, the first terminal receives the instruction from the second terminal information, the indication information is sent by the second terminal based on the interference cancellation information.

In some embodiments, the first terminal deactivates or releases or cancels or releases the configuration information corresponding to the released interference type based on the indication information.

In some embodiments, the first terminal may also deactivate or release or cancel or release the above configuration information on its own after detecting that the interference between the first frequency band and the second frequency band is removed. Steps 603 and 604 are optional steps at this time.

In some embodiments, the first terminal may also deactivate or release or cancel or release the above configuration information on its own after sending the interference release information. Step 604 is an optional step at this time.

To sum up, the method provided by this embodiment can enable configuration information only when interference occurs by reporting interference indication information from the first terminal, reducing the impact of configuration information on part of the time unit and improving the overall transmission rate. Or reduce transmission delay. In the same way, deactivating the configuration information when the interference is removed can also reduce the impact of the configuration information on part of the time unit, improve the overall transmission rate or reduce the transmission delay.

Illustratively, the second condition used to determine harmonic interference includes any of the following:

·The received signal strength on the second frequency band is higher than or equal to the first threshold;

·The received signal strength on the second frequency band is higher than or equal to the first threshold, and the transmitted signal strength on the first frequency band is lower than or equal to the second threshold;

·The transmitted signal strength on the first frequency band is lower than or equal to the second threshold;

·The signal-to-noise ratio on the second frequency band is higher than or equal to the third threshold, and the transmitted signal strength on the first frequency band is lower than or equal to the second threshold.

Fourth condition:

Illustratively, the first frequency band includes a transmitting carrier and a receiving carrier. In uplink and downlink communication scenarios, the sending carrier is the uplink carrier, and the receiving carrier is the downlink carrier. The fourth condition used to determine intermodulation interference includes any of the following:

·The received signal strength on the receiving carrier is higher than or equal to the third threshold;

·The received signal strength on the receiving carrier is higher than or equal to the third threshold, and the transmit signal strength on the transmitting carrier and/or the second frequency band is lower than or equal to the fourth threshold;

·The transmitting signal strength on the transmitting carrier and/or the second frequency band is lower than or equal to the fourth threshold;

·The signal-to-noise ratio on the receiving carrier is higher than or equal to the third threshold;

·The signal-to-noise ratio on the receiving carrier is higher than or equal to the third threshold, and the transmit signal strength on the transmitting carrier and/or the second frequency band is lower than or equal to the fourth threshold.

In some embodiments, the modes supported by the first frequency band and the second frequency band include at least one of FDD and TDD. The first frequency band includes one or more carriers, and the second frequency band includes one or more carriers. In FDD mode, a carrier is one of uplink carrier, downlink carrier, transmitting carrier and receiving carrier. In TDD mode, one carrier supports both sending and receiving, or uplink and downlink at the same time.

In different embodiments, the first frequency band uses FDD mode and the second frequency band uses TDD mode; or the first frequency band uses FDD mode and the second frequency band uses FDD mode; or the first frequency band uses TDD mode and the second frequency band uses TDD mode. Typically, the following example uses the FDD mode in the first frequency band and the TDD mode in the second frequency band. Other types of implementations can be easily thought of and reasoned by those skilled in the art based on the following descriptions, and will not be described again one by one.

Referring schematically to Figures 11 and 12, the first frequency band uses the FDD mode. Assuming that the first frequency band supports uplink and downlink communication scenarios, the first frequency band includes uplink carriers and downlink carriers. If the first frequency band supports a sidelink communication scenario, the first frequency band includes a transmitting carrier and a receiving carrier. The second frequency band uses the TDD mode, and the second frequency band includes a TDD carrier. The TDD carrier may be a carrier used in uplink and downlink communication scenarios, or a carrier used in sidelink communication, which is not limited here. Take at least one time unit as 10 time slots, the first frequency band is the LTEB3 frequency band, and the second frequency band is the NRn77 frequency band as an example:

In the uplink carrier, the default configuration information is that each time slot is an uplink time slot or all uplink time slots, abbreviated as U. In the downlink carrier, the default configuration information is that each time slot is a downlink time slot or all downlink time slots, abbreviated as D.

In a TDD carrier, the default configuration information is that there is both uplink time slot U and downlink time slot D. In some embodiments, the TDD carrier also includes flexible time slots, abbreviated as S. The symbols in the flexible time slot can be uplink symbols, downlink symbols, or both uplink symbols and downlink symbols. That is, the transmission attributes of each symbol in the flexible time slot can be flexibly matched. In this application, a flexible time slot can be considered as a time slot with transmitting attributes or uplink attributes, or as a time slot with receiving attributes or downlink attributes.

As shown by the downward arrow in Figure 12, in a certain first time slot, when there is a transmit signal in the uplink time slot of the uplink carrier, harmonic interference will occur to the received signal on the downlink time slot of the TDD carrier. . As shown by the upward arrow in Figure 12, in a certain second time slot, when there is a transmit signal in the uplink time slot of the uplink carrier, a transmit signal in the uplink time slot of the TDD carrier, and a receive signal in the downlink time slot of the downlink carrier In the case of , the intermodulation signals of the two transmitting signals will cause intermodulation interference to the receiving signal.

Therefore, from the time dimension, there is mutual interference between the two frequency bands in almost all time slots. When the interference intensity is relatively high, the base station will not configure this frequency band combination.

For harmonic interference:

Figure 13 shows a flow chart of an interference solution method within a carrier combination provided by an exemplary embodiment of the present application. The method is executed by the first terminal, and the method includes:

Step 701: The first terminal sends the first interference indication information when the first condition is met;

The first interference indication information is used to indicate the occurrence of harmonic interference in the first frequency band and the second frequency band. Optionally, the first interference indication information carries at least one of: an identifier of the first frequency band, an identifier of the uplink carrier, an identifier of the downlink carrier, an identifier of the second frequency band, an identifier of the TDD carrier, and an interference type indication of harmonic interference. kind of information.

Step 702: The first terminal receives the first configuration information of the first frequency band and/or the second frequency band;

The first configuration information is sent by the network device based on the first interference indication information.

The first configuration information is used to configure the uplink time slot of the uplink carrier and the downlink time slot or flexible time slot of the TDD carrier to be in different time slots. Optionally, the first configuration information is used for at least one of the following:

·Configure the first time slot in the uplink carrier from the uplink time slot to the restricted transmission time slot. The first time slot is the downlink time slot or flexible time slot in the TDD carrier;

·Configure the first time slot in the TDD carrier from the downlink time slot or flexible time slot to the restricted reception time slot, and the first time slot is the uplink time slot in the uplink carrier;

·Change the first time slot in the TDD carrier from the downlink time slot or flexible time slot to the uplink time slot. The first time slot is the uplink time slot in the uplink carrier.

Step 703: If the first terminal meets the second condition, send the first interference release information;

The first interference removal information is used to indicate that the harmonic interference between the first frequency band and the second frequency band has been removed. Optionally, the first interference relief information carries at least one of: an identifier of the first frequency band, an identifier of the uplink carrier, an identifier of the downlink carrier, an identifier of the second frequency band, an identifier of the TDD carrier, and an interference type indication of harmonic interference. kind of information.

·RSRP on the TDD carrier is higher than or equal to the first threshold;

·The RSRP on the TDD carrier is higher than or equal to the first threshold, and the transmitted signal strength on the uplink carrier is lower than or equal to the second threshold;

·The SINR on the TDD carrier is higher than or equal to the third threshold;

·The SINR on the TDD carrier is higher than or equal to the third threshold, and the transmitted signal strength on the uplink carrier is lower than or equal to the second threshold.

Step 704: The first terminal receives the first indication information, the first indication information is used to deactivate the first configuration information.

The first indication information is sent by the network device based on the first interference relief information. The first instruction information is used to deactivate or release or cancel or release the above-mentioned first configuration information.

Example 1:

As shown schematically in Figure 14, for the situation where harmonic interference occurs in the FDD frequency band and TDD frequency band, a direct way is to not transmit the uplink carrier in the FDD frequency band in the downlink time slot of the TDD frequency band. At this time, the uplink carrier The time slots are aligned with the uplink time slots of the TDD frequency band, which ensures that the uplink time slots of the FDD frequency band and the TDD downlink time slots do not overlap or appear at the same time. And usually, the uplink service of the FDD frequency band is less than the downlink service. That is to say, in many cases, the uplink carrier service volume of the FDD frequency band is limited. Therefore, the uplink time slots of terminals configured with the frequency band combination "FDD frequency band + TDD frequency band" are restricted. It has certain feasibility. This means that for this terminal, when configured to operate in a single frequency band in FDD mode, its uplink carrier can transmit uplink in all time slots, and when configured as a frequency band combination of "FDD frequency band + TDD frequency band" , the uplink carrier of the terminal will follow the uplink time slot configuration of the TDD frequency band.

Of course, for terminals, limiting the uplink time slots of the uplink carrier in the FDD frequency band will lead to a decrease in the maximum throughput capability of the uplink carrier, and at the same time, an improvement in the downlink throughput capability (compared to interference) Condition). Therefore, this processing method is more suitable for situations where the terminal performs downlink large throughput services and uplink small throughput services. Moreover, it is more suitable for situations where the transmit signal in the FDD frequency band has a relatively large impact on the received signal in the TDD frequency band, such as when the SINR decreases significantly. Because when the downlink receiving signal in the TDD frequency band is relatively strong and the interference signal in the FDD frequency band is relatively weak, the impact on the terminal's downlink throughput service is not obvious. At this time, there is no need to perform uplink time slots of the uplink carrier in the FDD frequency band. limit.

Therefore, when to trigger the base station to limit the uplink time slots of the FDD frequency band should be determined based on the actual interference situation and business conditions of the terminal. A feasible way is for the terminal to proactively report harmonic high interference indication information (or uplink time slot restriction request information or harmonic interference indication information or first interference indication information called FDD frequency band) to the base station, and the base station performs FDD processing based on this information. The uplink carrier of the frequency band is configured with an uplink time slot template (Txpattern). The base station only schedules the terminal for uplink transmission in the corresponding uplink time slot, and the corresponding terminal only transmits in the uplink time slot of the corresponding FDD frequency band.

When the actual interference situation or service situation of the terminal changes (the interference becomes weaker or the traffic demand decreases), the terminal further proactively reports the harmonic high interference removal indication information (also known as the request information to remove the uplink time slot restriction of the FDD frequency band or the third an interference contact information) to the base station. After receiving this information, the base station releases the restriction on the uplink carrier uplink time slot in the FDD frequency band (deactivates/releases the Tx pattern).

The terminal can judge the actual interference situation by measuring the RSRP of the TDD received signal, the SINR of the TDD received signal, and/or the FDD transmit signal strength.

One method is for the terminal to judge only by the RSRP of the TDD frequency band (the interfered frequency band). For example, when the RSRP is lower than a certain threshold, the terminal considers it to be at the edge of the cell. At this time, its received signal is relatively weak and is susceptible to interference from the FDD frequency band. . Therefore, the terminal reports high harmonic interference indication information to the base station.

Optionally, the terminal can further determine based on the transmit signal strength of the FDD frequency band. For example, when the transmit signal strength of the FDD frequency band is higher than a certain threshold (that is, the received signal strength of the TDD frequency band is lower than a certain threshold, and the transmit signal strength Higher than a certain threshold), the terminal determines that this is a scenario where harmonic interference is prone to occur, and reports high harmonic interference indication information to the base station.

Another method is for the terminal to judge by measuring the SINR of the interfered frequency band of the TDD frequency band. SINR directly reflects the signal-to-noise ratio of the received signal. When it is lower than a certain threshold, it will have a direct impact on throughput. Therefore, the interference intensity at this time can be judged by the SINR size, that is, when the SINR is lower than a certain threshold, the terminal reports harmonic high interference indication information to the base station.

Optionally, the terminal can further judge based on the transmit signal strength of the FDD frequency band, for example, when the transmit signal strength of the FDD frequency band is higher than a certain threshold (that is, the received SINR in the TDD frequency band is lower than a certain threshold, and the transmit signal strength is high reaches a certain threshold), the terminal determines that this is a scenario where harmonic interference is prone to occur, and reports high harmonic interference indication information to the base station.

Optionally, the terminal can further determine based on the received signal strength in the TDD frequency band. For example, when the received signal in the TDD frequency band is lower than a certain threshold, the terminal determines that this is a scenario prone to harmonic interference and reports high harmonic interference indication information. to the base station.

Example 2:

As shown in Figure 15, another method to solve the interference of the FDD carrier transmit signal on the TDD carrier receive signal is to define "change time slots" for the uplink carrier of the FDD carrier. That is, in these time slots, the uplink carrier of the FDD carrier can be used. Perform downlink reception of FDD carriers. At this time, the uplink carrier and downlink carrier of the FDD carrier will be used for downlink reception together. Its working mode can be similar to CA or DC mode, in which one carrier can be used as the main carrier and the other carrier as the auxiliary carrier.

In this way, there will be no uplink transmission of the FDD carrier in the downlink time slot of the TDD carrier, that is, harmonic interference between the two is avoided.

Similar to Example 1, when the terminal determines that this is a high harmonic interference scenario (the judgment method is the same as Example 1 above), it will report high harmonic interference indication information (or called uplink time in the FDD band) to the base station. slot limit request information). After receiving this indication information, the base station will configure the uplink carrier time slot configuration of the FDD frequency band through RRC signaling, that is, configure the uplink carrier time slot template (uplink/downlink pattern) of the FDD frequency band. The base station will only configure the uplink carrier time slot template corresponding to the uplink carrier time slot template. The terminal is scheduled to perform uplink transmission of the uplink carrier in the FDD frequency band only in the uplink time slot, and the terminal is scheduled to use the uplink carrier in the downlink time slot corresponding to the uplink carrier time slot template for downlink reception.

When the actual interference situation or service situation of the terminal changes (the interference becomes weaker or the traffic demand decreases), the terminal further proactively reports the high interference removal indication information (also known as the uplink time slot restriction removal request information of the FDD frequency band or the first interference Release information) to the base station. After receiving this information, the base station deactivates the uplink carrier time slot template of the FDD frequency band (deactivates/releases the uplink/downlink pattern).

For intermodulation interference:

Figure 16 shows a flow chart of an interference solution method within a carrier combination provided by an exemplary embodiment of the present application. The method is executed by the first terminal, and the method includes:

Step 801: When the third condition is met, the first terminal sends the second interference indication information;

The second interference indication information is used to indicate that intermodulation interference occurs between the first frequency band and the second frequency band. Optionally, the second interference indication information carries at least one of: an identifier of the first frequency band, an identifier of the uplink carrier, an identifier of the downlink carrier, an identifier of the second frequency band, an identifier of the TDD carrier, and an interference type indication of intermodulation interference. kind of information.

The third condition is a condition for detecting intermodulation interference. The third condition (for the same second time slot) includes any of the following:

·RSRP on the downlink carrier is lower than the third threshold;

·The RSRP on the downlink carrier is lower than the third threshold, and the transmit signal strength on the uplink carrier and/or TDD carrier is higher than the fourth threshold;

·The transmit signal strength on the uplink carrier and/or TDD carrier is higher than the fourth threshold;

·The SINR on the downlink carrier is lower than the third threshold;

·The SINR on the downlink carrier is lower than the third threshold, and the transmit signal strength on the uplink carrier and/or TDD carrier is higher than the fourth threshold.

Step 802: The first terminal receives the second configuration information of the first frequency band and/or TDD carrier;

The second configuration information is sent by the network device based on the second interference indication information.

The second configuration information is used to configure the uplink time slot of the uplink carrier and the uplink time slot or flexible time slot of the TDD carrier to be in different time slots. Alternatively, the second configuration information is used to configure the downlink time slot of the downlink carrier and the uplink time slot or flexible time slot of the TDD carrier to be in different time slots.

The second configuration information is used for at least one of the following:

· Configure the second time slot in the uplink carrier from the uplink time slot to the restricted transmission time slot, the second time slot is the uplink time slot or flexible time slot in the TDD carrier and the second time slot is the downlink time slot in the downlink carrier ;

·Change the second time slot in the uplink carrier from the uplink time slot to the downlink time slot, the second time slot is the uplink time slot or flexible time slot in the TDD carrier and the second time period is the downlink time slot of the downlink carrier;

·Change the second time slot in the TDD carrier from the uplink time slot or flexible time slot to the downlink time slot;

·Change the second time slot in the downlink carrier from a downlink time slot to an uplink time slot, and the second time slot in the uplink carrier and TDD carrier is an uplink time slot or a flexible time slot;

·Change the second time slot in the TDD carrier from a downlink time slot to an uplink time slot or a flexible time slot.

It should be noted that the above second configuration information does not exhaust all possible implementation methods, but is only an exemplary description.

Step 803: When the fourth condition is met, the first terminal sends the second interference release information;

The second interference removal information is used to indicate that the intermodulation interference between the first frequency band and the TDD carrier has been removed. Optionally, the second interference relief information carries: at least one of the identification of the first frequency band, the identification of the uplink carrier, the identification of the downlink carrier, the identification of the TDD carrier, the identification of the TDD carrier, and the interference type indication of intermodulation interference. information.

The fourth condition is a condition for detecting intermodulation interference. The fourth condition (for the same second time slot) includes any of the following:

·The RSRP on the downlink carrier is higher than or equal to the third threshold;

·The RSRP on the downlink carrier is higher than or equal to the third threshold, and the transmit signal strength on the uplink carrier and/or TDD carrier is lower than or equal to the fourth threshold;

·The transmitted signal strength on the uplink carrier and/or TDD carrier is lower than or equal to the fourth threshold;

·The SINR on the downlink carrier is higher than or equal to the third threshold;

·The SINR on the downlink carrier is higher than or equal to the third threshold, and the transmit signal strength on the uplink carrier and/or TDD carrier is lower than or equal to the fourth threshold.

Step 804: The first terminal receives the second instruction information, the second instruction information is used to deactivate the second configuration information.

The second indication information is sent by the network device based on the second interference relief information. The second instruction information is used to deactivate or release or cancel or release the above-mentioned second configuration information.

As mentioned above, the generation of intermodulation signals requires two signals transmitted at the same time. After the two signals are amplified by nonlinear devices inside the terminal, the intermodulation products of the two signals will be obtained. When the intermodulation products fall into Intermodulation interference will occur after receiving the frequency band. Therefore, the suppression of intermodulation interference can be considered from two aspects. One is to ensure that no two signals are transmitted uplink at the same time; the other is to ensure that when there are signals transmitted uplink at the same time, the downlink reception of the carrier is not interfered with. Therefore, you can start with the following methods.

Example 3:

As shown in Figure 17, at the uplink time slot of the TDD frequency band, the uplink carrier of the FDD frequency band will be configured as a restricted transmission time slot, that is, no uplink transmission of the uplink carrier will be performed. This way it is ensured that no intermodulation interference occurs.

When the terminal detects that intermodulation interference occurs, the terminal will report high intermodulation interference indication information (or uplink time slot restriction request information or intermodulation interference indication information or second interference indication information) to the base station. After receiving the indication information, the base station will configure and send an uplink time slot template (Txpattern) to the uplink carrier in the FDD frequency band, and the terminal will only perform uplink transmission in the uplink time slot corresponding to the uplink time slot template. When the terminal detects the actual interference situation or the service situation changes (the interference weakens or the traffic demand decreases), the terminal further proactively reports the intermodulation high interference removal indication information (also known as the uplink transmission time slot restriction removal request information or the second Interference cancellation information) to the base station. After receiving this information, the base station releases the restriction on the FDD uplink carrier transmission time slot (deactivates/releases Tx pattern).

Example 4:

As shown in Figure 18, similar to Example 2, the "change time slot" is defined. For the second time slot corresponding to the intermodulation interference, the downlink time slot of the downlink carrier is adjusted to the uplink time slot, thereby avoiding the intermodulation signal band Interference comes.

Example 5:

As shown in Figure 19, similar to Example 2, "change time slot" is defined. For the second time slot corresponding to the intermodulation interference, the uplink carrier of the FDD frequency band is adjusted from the uplink time slot to the downlink time slot, thereby avoiding mutual interference.
