Detailed Description

Referring to fig. 1, fig. 1 is a structural diagram of a network system applicable to the embodiment of the present invention, and as shown in fig. 1, the network system includes a user terminal 11, a first base station 12, and a second base station 13, where the user terminal 11 may be a ue (user equipment), for example: the terminal side Device may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), or a Wearable Device (Wearable Device), and it should be noted that the specific type of the user terminal 11 is not limited in the embodiments of the present invention. The user terminal 11 may establish communication with the first base station 12 and the second base station 13 at the same time, and the first base station 12 may be a base station in the first system, for example: a base station in a Long Term Evolution (LTE) system, and the second base station 13 may be a base station in a second system, for example: a base station in a 5G New Radio (NR) system.

In the embodiment of the present invention, the first system and the second system may be tightly coupled in a Dual Connectivity (DC) manner. One of the systems is used as a Master Node (MN), and the other system is used as a Secondary Node (SN). And in a dual connectivity system, two Cell groups are included, a Master Cell Group (MCG) and a Secondary Cell Group (SCG). The Primary Cell group may include one Primary Cell (PCell) and one or more Secondary cells (scells), and the Secondary Cell group may include one Primary Secondary Cell (PSCell) and one or more scells.

In the network system, the ue 11 may perform data transmission with the first base station 12 and the second base station 13 at the same time, or may perform data transmission with the first base station 12 and the second base station 13 at different times, which is not limited in the embodiment of the present invention.

Referring to fig. 2, fig. 2 is a flowchart of a terminal self-interference processing method provided in an embodiment of the present invention, where the method is applied to a user equipment, and as shown in fig. 2, the method includes the following steps:

step 201, determining the resource which will generate the terminal self-interference.

In addition, the terminal self-interference may be interference generated by a signal transmitted by the user terminal itself, which affects a received signal of the user terminal itself, for example: the user terminal sends the influence of the uplink signal on the downlink signal received by the user terminal. And the terminal self-interference may be harmonic interference, cross modulation interference, or harmonic mixing interference (harmonic mixing), where the harmonic interference may be second harmonic interference or other harmonic interference, for example: third harmonic interference, and the like. The above-mentioned intermodulation interference may be secondary intermodulation interference, or other intermodulation interference, such as: third intermodulation interference, etc. It should be noted that the embodiment of the present invention does not limit the type of terminal self-interference.

In addition, the resource that generates the terminal self-interference may be, if the transmission method of the resource is not changed, the terminal self-interference may be generated during the resource transmission, for example: if data transmission is performed according to the scheduling result configured for the resource by the base station, self-interference of the terminal may be generated during the resource transmission. Alternatively, the resource that will generate the terminal self-interference may be understood as a resource that may generate the terminal self-interference.

In addition, the resources may include time domain resources, frequency domain resources, or time frequency domain resources.

Step 202, in the resource, data transmission is performed according to the partial scheduling result of the base station, or the transmission power corresponding to the partial scheduling result of the base station is reduced.

The partial scheduling result of the base station may be a partial scheduling result selected from at least two scheduling results corresponding to the resources sent by the base station, for example: the at least two scheduling results corresponding to the resources include a downlink scheduling result of the NR system and an uplink scheduling result of the LTE system, and the user terminal may select the downlink scheduling result or the uplink scheduling result for data transmission, thereby avoiding self-interference of the terminal.

The reducing of the transmission power corresponding to the partial scheduling result of the base station may be reducing of the transmission power of the uplink connection corresponding to the partial scheduling result of the base station, so that the interference of the uplink signal to the downlink signal may be reduced. For example: and the at least two scheduling results corresponding to the resources comprise a downlink scheduling result of the NR system and an uplink scheduling result of the LTE system, so that the transmitting power of uplink connection of the LTE system can be reduced, uplink transmission is performed according to the uplink scheduling result, and downlink transmission is performed according to the downlink scheduling result.

In this embodiment, on the resource that will generate the terminal self-interference, data transmission is performed according to the partial scheduling result of the base station, or the transmission power corresponding to the partial scheduling result of the base station is reduced, so that the terminal self-interference can be reduced, and the transmission performance of the user terminal is improved.

Referring to fig. 3, fig. 3 is a flowchart of a terminal self-interference processing method provided in an embodiment of the present invention, where the method is applied to a user equipment, and as shown in fig. 3, the method includes the following steps:

step 301, determining a target frequency point which may be affected by terminal self-interference by the user terminal according to the frequency point information configured for the user terminal by the base station.

The frequency point information may be uplink working frequency point information of the user terminal, for example: if the LTE uplink frequency point configured for the terminal by the base station is 1720MHz to 1740MHz, the frequency point possibly influenced by the second harmonic interference of the user terminal is judged to be a 5G downlink frequency point: 3440MHz to 3480 MHz. And the bandwidth of the NR system on the network side and the central frequency point can be combined, for example, the bandwidth of the NR system is 3460MHz to 3500MHz, and finally, the frequency point which is possibly influenced by the second harmonic interference of the user terminal is 3460MHz to 3480 MHz.

Another example is: when the UE performs LTE and NR dual connectivity, if the LTE uplink frequency point configured for the user terminal by the base station is 1720MHz to 1740MHz, and the 5G NR uplink frequency point is 3485MHz to 3525MHz, it is determined that the frequency point range that the user terminal may be affected by the intermodulation interference is the LTE downlink frequency point: 1745MHz-1805 MHz. And the LTE system bandwidth and the center frequency point on the network side may be combined, for example, the LTE system bandwidth is 1765MHz to 1775MHz, and it is finally determined that the frequency point which may be affected by the intermodulation interference is 1765MHz to 1775 MHz.

Step 302, determining whether the user terminal generates terminal self-interference when performing data transmission according to a scheduling result sent by a base station according to the transmission parameter of the user terminal on the target frequency point, wherein the scheduling result is a scheduling result corresponding to a resource corresponding to the target frequency point.

Wherein, the transmission parameter may include at least one of the following:

sensitivity backset value of received signal, interference isolation index value, transmitting power of transmitted signal, demodulation threshold of received signal and sensitivity of received signal.

Of course, in the embodiment of the present invention, the transmission parameters are not limited, for example: but also sensitivity backset value of received signal, interference isolation index value, transmitting power of transmitted signal, demodulation threshold of received signal and other parameters besides sensitivity of received signal.

The determining, according to the transmission parameter of the user terminal on the target frequency point, whether the user terminal performs data transmission according to the scheduling result sent by the base station and generates terminal self-interference may be determining whether the transmission parameter presets a terminal self-interference condition, and if so, determining that the user terminal performs data transmission according to the scheduling result sent by the base station and generates terminal self-interference, otherwise, generating no terminal self-interference. Or, it may be determined whether the transmission parameter satisfies a preset threshold, and if so, it may be determined that the terminal self-interference may be generated when the user terminal performs data transmission according to a scheduling result sent by the base station, otherwise, the terminal self-interference may not be generated. And when the transmission parameters include a plurality of parameters, whether the relationship among the plurality of parameters meets a preset condition can be judged, if yes, it can be determined that the terminal self-interference is generated when the user terminal performs data transmission according to the scheduling result sent by the base station, otherwise, the terminal self-interference is not generated.

In addition, the scheduling result corresponding to the resource corresponding to the target frequency point may be a scheduling result for scheduling the user terminal to perform data transmission on the resource, for example: the uplink scheduling result of the uplink transmission on the resource and the downlink scheduling result of the downlink resource on the resource. And the scheduling result sent by the base station may be a scheduling result sent by one or more base stations, and may be sent to the user terminal before step 302.

Step 303, if the user terminal performs data transmission according to the scheduling result sent by the base station and generates terminal self-interference, determining that the resource corresponding to the target frequency point is a resource which will generate terminal self-interference.

And if the user terminal performs data transmission according to the scheduling result sent by the base station and generates terminal self-interference, determining that the resource corresponding to the target frequency point is a resource which will generate the terminal self-interference, because the user terminal generates the terminal self-interference on the resource if the user terminal performs data transmission on the resource according to the scheduling result.

Optionally, after determining, according to the transmission parameter of the user terminal on the target frequency point, whether the terminal self-interference may be generated when the user terminal performs data transmission according to the scheduling result sent by the base station, the method further includes:

and if the user terminal does not generate terminal self-interference when transmitting data according to the scheduling result sent by the base station, transmitting the data according to the scheduling result.

In this embodiment, if it is determined that the terminal self-interference is not generated, data transmission may be performed according to the scheduling result.

It should be noted that, in this embodiment, steps 301 to 303 are optional, for example: the resource for determining that the terminal self-interference will be generated may also be preset by the user terminal, or notified by the base station, and the like, which is not limited in the embodiment of the present invention.

And 304, transmitting data on the resources according to the partial scheduling result of the base station, or reducing the transmission power corresponding to the partial scheduling result of the base station.

In step 304, if the self-interference of the terminal may be generated when the user terminal performs data transmission according to the scheduling result sent by the base station, the user terminal performs data transmission on the resource according to a part of the scheduling result of the base station, or reduces the transmission power corresponding to the part of the scheduling result of the base station. Or, if it is determined that the terminal self-interference is generated and the terminal self-interference satisfies a certain condition, data transmission is performed on the resource according to the partial scheduling result of the base station, or transmission power corresponding to the partial scheduling result of the base station is reduced. For example: after determining whether the user terminal will generate terminal self-interference on the resource corresponding to the target frequency point according to the transmission parameters of the user terminal on the target frequency point, the method further includes:

determining the influence degree of the terminal self-interference according to the transmission parameters of the user terminal on the target frequency point;

the performing, on the resource, data transmission according to the partial scheduling result of the base station, or reducing transmission power corresponding to the partial scheduling result of the base station includes:

and if the influence degree of the self-interference of the terminal reaches a preset influence degree, carrying out data transmission on the resources according to a part of scheduling results of the base station, or reducing the transmission power corresponding to the part of scheduling results of the base station.

Wherein, the influence degree of the terminal self-interference may be an influence magnitude of the terminal self-interference, for example: according to the interference isolation index value (70dB), the transmitting power (20dBm) of the transmitting signal and the demodulation threshold or sensitivity (-95dBm) of the downlink receiving signal, the user terminal judges that the size of the second harmonic interference is 20-70-50 dBm and is far larger than the demodulation threshold or sensitivity (-95dBm) of the downlink receiving signal, and therefore the influence degree is determined to be serious interference. Another example is: and determining the influence degree as serious interference according to the sensitivity back-off value (-20dB) of the received signal of the user terminal. In addition, the influence degree of the terminal self-interference reaching the preset influence degree may be that the influence of the terminal self-interference is greater than a preset influence threshold.

Through the steps, if the self-interference of the terminal is determined to be generated and the influence degree of the self-interference of the terminal reaches the preset influence degree, data transmission is carried out on the resources according to the partial scheduling result of the base station, or the transmission power corresponding to the partial scheduling result of the base station is reduced. This may further improve the performance of the user terminal in handling terminal self-interference. For example: if the terminal self-interference is generated, but the influence degree of the terminal self-interference is low, data transmission can be directly performed according to the existing mode without adopting a transmission mode for avoiding the terminal self-interference, and therefore, the influence of the terminal self-interference is small under the condition.

Optionally, the performing, on the resource, data transmission according to the partial scheduling result of the base station, or reducing transmission power corresponding to the partial scheduling result of the base station includes:

identifying the type of the terminal self-interference according to at least two scheduling results of the base station;

and on the resources, performing data transmission according to a part of scheduling results corresponding to the type of the terminal self-interference, or reducing transmission power of a base station corresponding to the part of scheduling results corresponding to the type of the terminal self-interference.

The at least two scheduling results of the base station may be at least two scheduling results corresponding to the resource sent by the base station, that is, the at least two scheduling results are scheduling results for scheduling the user terminal to perform data transmission on the resource. In addition, the type of the terminal self-interference may be cross-modulation interference, harmonic mixing interference, or the like. Preferably, the harmonic interference may be second harmonic interference or other harmonic interference. In addition, the above intermodulation interference may be second-order intermodulation (IMD2, 2nd order intermodulation) and other high-order intermodulation interference, such as: the user terminal simultaneously transmits the generated intermodulation interference, including second-order intermodulation and other high-order intermodulation interference, in the Band3 frequency Band 1.8GHz UL (Uplink) and 3.5GHz UL. Other high order intermodulation such as IMD3(3rd order intermodulation) generates a near zero frequency intermodulation product from the mathematical relationship, which may appear at the LNA (Low Noise Amplifier) output of the LTE receiver, and if the isolation of the later cascaded mixer (mixer) is limited at the near zero frequency, the product will leak directly to the output of the mixer, and further affect the receiving performance.

For example: taking LTE and 5G NR dual connection using LTE FDD spectrum of 1.8GHz and NR TDD spectrum of 3.5GHz as an example, as shown in fig. 4, the user terminal establishes communication with the LTE base station and the NR base station, where the at least two scheduling results include an uplink scheduling result sent by the LET base station on the resource and a downlink scheduling result sent by the NR base station on the resource, so that the uplink signal may generate terminal self-interference on the downlink signal, that is, the uplink signal is an interference source link and the downlink signal is an interfered link, thereby determining the uplink signal to be harmonic interference.

Another example is: taking LTE and 5G NR dual connection using LTE FDD spectrum of 1.8GHz and NR TDD spectrum of 3.5GHz as an example, as shown in fig. 5, the user terminal establishes communication with the LTE base station and the NR base station, where the at least two scheduling results include an uplink scheduling result sent by the LTE base station on the resource, an uplink scheduling result sent by the NR base station on the resource, and a downlink scheduling result sent by the LTE base station on the resource, so that the two uplink signals generate terminal self-interference on the downlink signal, and thus determine the uplink and downlink interference.

The data transmission according to the partial scheduling result corresponding to the type of the terminal self-interference may be performed by selecting a partial scheduling result from the at least two scheduling results according to the type of the terminal self-interference, and performing data transmission according to the selected scheduling result, so as to achieve an effect of avoiding the terminal interference. For example: for harmonic interference, one scheduling result may be selected, and data transmission may be performed according to the one scheduling result, and for intermodulation interference, two scheduling results may be selected, and data transmission may be performed according to the two scheduling results. Or, all scheduling results may be selected, but the transmit power of the uplink connection is reduced during transmission, thereby achieving the effect of reducing the self-interference of the terminal.

In this embodiment, since data transmission is performed according to the partial scheduling result corresponding to the type of the terminal self-interference, the terminal self-interference can be flexibly processed, so that the flexibility of processing the terminal self-interference by the user terminal is improved. Of course, in the embodiment of the present invention, not identifying the type of the terminal self-interference may also be implemented, for example: and directly selecting a part of scheduling results for data transmission, thereby avoiding the generation of self-interference of the terminal, or reducing the transmitting power of one or more uplink connections, so as to reduce the influence of the self-interference of the terminal.

Optionally, the performing, on the resource, data transmission according to a partial scheduling result corresponding to the type of the terminal self-interference, or reducing transmission power of the base station corresponding to the partial scheduling result corresponding to the type of the terminal self-interference includes:

or,

Wherein, the above-mentioned selection of an uplink or downlink scheduling result may be selected by the user terminal, for example: the selection may be random or based on priority or importance of the scheduling result. The above-mentioned reducing the transmission power corresponding to the uplink scheduling result may be reducing based on the transmission power set for the uplink connection corresponding to the uplink scheduling result, where the reduction range may be preset, or the user terminal may be flexibly set, and the like.

By the embodiment, the user terminal can flexibly select part of scheduling results for data transmission aiming at harmonic interference and/or harmonic mixing interference so as to improve the flexibility of the user terminal in processing the self-interference of the terminal; or, the important signal or the important channel is selected for data transmission, so as to ensure the performance of the important signal or the important channel of the user terminal. For example: if the Paging message (Paging) is scheduled downlink at this time and the PUSCH of the general service is scheduled uplink, the UE receives the Paging message (Paging) without transmitting the PUSCH. Or, it may also implement selecting all scheduling results for data transmission, but reduce the transmission power corresponding to the uplink scheduling result to reduce the influence of the terminal self-interference, and may also include data transmission of the user terminal.

It should be noted that the important signals and the important channels may be predefined by the ue, or agreed by a protocol, or configured by the base station. And the two scheduling results corresponding to the resources sent by the base station may be two scheduling results corresponding to the resources sent by the two base stations, and the two scheduling results are used for scheduling the user terminals to transmit data simultaneously.

Randomly or according to a priority or importance level. The above-mentioned reducing the transmission power corresponding to the uplink scheduling result may be reducing based on the transmission power set for the uplink connection corresponding to the uplink scheduling result, where the reduction range may be preset, or the user terminal may be flexibly set, and so on.

In addition, one of the three scheduling results includes an uplink important signal and/or an uplink important channel, and the other uplink scheduling result does not include the uplink important signal and/or the uplink important channel may be that the first uplink scheduling result includes the uplink important signal and/or the uplink important channel, and the second uplink scheduling result does not include the uplink important signal and/or the uplink important channel; or, the second uplink scheduling result may include the uplink important signal and/or the uplink important channel, and the first uplink scheduling result may not include the uplink important signal and/or the uplink important channel.
