Among them, carrier aggregation is a key technology in LTE-A. In the case of limited band resources, carrier aggregation has a significant qualitative improvement in data transmission rate. At present, carrier aggregation of user equipment combines a low frequency band (LOW Band) and a high frequency band (High Band) to implement inter-band carrier aggregation (Inter-CA). However, for the carrier aggregation band combination of the low band-high band, there is a problem that the harmonics of the low band fall within the reception band of the high band.

Specifically, due to the nonlinearity of the antenna switching device itself, the fundamental wave entering the antenna switching device generates second harmonics, third harmonics, and the like.

Carrier Aggregation (CA) technology is an important feature of LTE-A technology. The CA is classified into three types: intra-band continuous, intra-band non-continuous, and inter-band. The embodiment of the present invention is a solution in the inter-band CA scenario. In the inter-band CA scenario, the band-band, that is, the difference in the working frequency band and the interference problem, are classified into different inter-band CA types (inter- Band CA class A1, inter-band CA class A2, inter-band CA class A3, and inter-band CA class A4).

For example, it may be a portable, pocket, handheld, computer built-in or in-vehicle mobile device that exchanges language and/or data with a wireless access network. For example, personal communication service (PCS, Personal Communication Service), cordless telephone, Session Initiation Protocol (SIP) telephone, Wireless Local Loop (WLL) station, personal digital assistant (PDA), etc. . A wireless terminal may also be called a system, a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, an access point, Remote terminal, access terminal, user terminal, user agent.

The base station may be an evolved Node B (eNB), a radio network controller (RNC), or a base station controller (BSC), that is, an access network device.

It should be noted that in the communication system, the base station and the user equipment communicate by data, and the information is transmitted. Specifically, the base station sends the downlink data to the user equipment, and the user equipment sends the uplink data to the base station, that is, the user equipment receives the downlink data and transmits the uplink data. Therefore, the type of the first data in the embodiment of the present invention may include uplink data and downlink data.

In the embodiment of the present invention, when the carrier aggregation mode is prepared, the user equipment needs to be based on the base. The station obtains the first frequency point information and the type of the first data configured when the first data is transmitted. The first frequency point information may include a first working frequency band and a first working frequency point on the first working frequency band. That is, in the carrier aggregation mode, the user equipment may acquire, from the base station, a first working frequency point for transmitting the first data and a type of the first data transmitted for the first working frequency band.

It should be noted that, in the user equipment, since the user equipment can obtain configuration information (configured frequency point information) for transmitting all data from the base station, the interference working frequency of the data during the transmission process can be calculated. Recording the data type and working frequency band and working frequency point transmitted on the interference working frequency point to form a code table, which is stored in the user equipment, for example, stored in the NV (NonVolatile) of the user equipment for subsequent judgment.

After the user equipment acquires the first frequency point information and the type of the first data that are configured when the first data is transmitted, the user equipment may determine, according to the first frequency point information and the type of the first data, that the first frequency point information is transmitted according to the first frequency point information. Whether there is interference when a data is used.

Specifically, the user equipment may determine, according to the type of the first data and the first working frequency band, whether the first working frequency point of transmitting the first data is an interference frequency point.

It should be noted that the method for solving interference provided by the embodiment of the present invention is performed in the background, and is a configuration work before the user equipment performs data transmission.

Further, in the embodiment of the present invention, the specific processing procedure of the user equipment to determine whether to generate interference when transmitting the first data according to the first frequency point information and the type of the first data is described in detail in subsequent embodiments.

S103. When the interference occurs, the user equipment configures the transmission of the first data update as the second frequency point letter. The working frequency band in the second frequency point information is higher than the working frequency band in the first frequency point information, and the first frequency point information and the second frequency point information are frequency point information in the carrier aggregation mode.

After the user equipment determines whether interference is generated when the first data is transmitted, when the interference occurs, the user equipment configures the transmission of the first data update as the second frequency point information. Specifically, when the user equipment is to transmit the first data, the first frequency point information transmission is not used, but the frequency band or frequency point corresponding to the second frequency point information is used for transmission, that is, the user equipment transmission is changed. Configuration information for a data. The working frequency band in the second frequency point information is higher than the working frequency band in the first frequency point information, and the first frequency point information and the second frequency point information are frequency point information in the carrier aggregation mode.

Working frequency band (that is, the frequency band in the CA combined frequency band).

It should be noted that, in the embodiment of the present invention, the working frequency band in the second frequency point information, that is, the second working frequency band, is higher than the working frequency band in the first frequency point information, that is, the first working frequency band. When the second working frequency band is specifically selected to transmit the first data, the interference is no longer generated.

In an embodiment, the second operating frequency band selects a high frequency band in the CA combined frequency band.

It can be understood that, in the embodiment of the present invention, the harmonic interference refers to when the working frequency band of the harmonic generated when the uplink data is transmitted in the working frequency band used by the user equipment falls within the working frequency band used when the user equipment transmits the downlink data. Interfering with receiving downlink data from the user equipment. For the user equipment, when receiving the downlink data, the user equipment receives the harmonics of the uplink data transmitted by the user equipment, which has a great influence on the communication of the user equipment. Therefore, to solve this problem, the uplink data should be transmitted. The working frequency band is configured in the high frequency band. In the user equipment, the primary radio frequency chip supports the transmission of uplink data and downlink data, and the secondary radio frequency chip supports the transmission of the downlink data. Therefore, in the case of harmonic interference, the configuration of the primary frequency chip in the user equipment is configured. The frequency band is in the high frequency band of the CA combined frequency band, and the corresponding working frequency band of the secondary RF chip is correspondingly configured. The low frequency band will solve the harmonic interference situation.

Illustratively, as shown in FIG. 3, based on the existing radio frequency frame, the radio frequency path after the method for resolving interference in the embodiment of the present invention is shown by the solid arrow in FIG. 3, at which time harmonic interference occurs. The working frequency band configured by the main frequency chip in the user equipment is in the high frequency band of the CA combined frequency band, and the working frequency band of the auxiliary radio frequency chip is correspondingly configured in the low frequency band. Therefore, according to the above configuration, the solid arrow in FIG. 3 is used. The RF path shown, with or without the RF path shown by the dashed arrow in Figure 3.

It should be noted that, since the scenario implemented in the embodiment of the present invention is a low-high frequency carrier aggregation and a harmonic interference problem, when there is harmonic interference, the working frequency band used for transmitting the uplink data is configured as a high frequency band. When the interfered other party transmits downlink data, the portion of the low frequency band in the low-high frequency carrier aggregation is used.

Specifically, when the type of the first data is uplink data, and the first data is transmitted to generate interference, the working frequency band of the uplink data transmitted in the primary radio frequency chip is configured as a high frequency band.

Exemplarily, the band 4 is a high frequency band, the band 17 is a low frequency band, and the first data is uplink data, and the uplink data is configured at a first working frequency point of the first working frequency band 17 , assuming that the band 4 and the band 17 carrier are aggregated. When it is determined that the uplink data is transmitted on the first frequency point, harmonic interference occurs. Therefore, the user equipment configures the working frequency band for transmitting the uplink data to be band 4.

Further, after the user equipment updates the second frequency point information configured to transmit the data, the user equipment may transmit the first data in the second working frequency point on the second working frequency band of the second frequency point information.

Further, as shown in FIG. 4, an embodiment of the present invention provides a method for resolving interference. After S102, the method further includes:

S104: When no interference occurs, the user equipment transmits the first data to be still configured as the first frequency point information.

After the user equipment determines whether interference is generated when the first data is transmitted, when no interference occurs, The user equipment may not change the frequency point information of the original configuration in which the first data is transmitted.

Further, after the user equipment is configured to transmit the working frequency band of the data, the user equipment may transmit the first data at the first working frequency point on the first working frequency band of the first frequency point information.

Exemplarily, the band 4 is a high frequency band, the band 17 is a low frequency band, and the first data is uplink data, and the uplink data is configured at a first working frequency point of the first working frequency band 17 , assuming that the band 4 and the band 17 carrier are aggregated. When it is determined that the uplink data is transmitted on the first frequency point, no harmonic interference occurs, and therefore, the user equipment continues to transmit uplink data at the first working frequency of the band 17.

It can be understood that the method for resolving interference provided by the embodiment of the present invention can flexibly configure the working frequency band of the main and auxiliary radio frequency chips by comparing the pre-stored code table, avoiding the interference caused by the harmonics, and solving the harmonic mutual interference in the carrier aggregation. problem. At the same time, since the interference of various harmonics can be filtered out without setting a special filter, the number of filters and the limitation of the selection of the antenna switching device are saved, and the cost and the printed circuit board (PCB, Printed Circuit) are reduced. Board) Layout area.

It should be noted that S103 and S104 in the embodiment of the present invention are the selection steps after S102, and one step is selected according to the actual detection situation; that is, in the embodiment of the present invention, after S102, S103 may be executed. S104 may be performed, and the specific execution sequence may be determined according to an actual situation, and is not limited by the embodiment of the present invention; and after the execution of S103 or S104, the current processing flow ends.

The method for resolving interference provided by the embodiment of the present invention obtains the first frequency point information and the type of the first data configured when the first data is transmitted in the carrier aggregation mode; and according to the first frequency point information and the first data Type, determining whether interference occurs when transmitting the first data; when generating interference, configuring the first data update to be the second frequency point information, where the working frequency band in the second frequency point information is larger than the working frequency band in the first frequency point information Preferably, the first frequency point information and the second frequency point information are frequency point information in a carrier aggregation mode. With the above technical implementation scheme, the user equipment reconfigures the interference frequency used for transmitting the uplink data in the carrier in the case of harmonic interference. The high frequency band in the aggregation mode, so that the transmission of the corresponding affected downlink data is in the low frequency band in the same carrier aggregation mode, so that the working frequency band of the harmonic generated during the uplink data transmission is far away from the original affected downlink data. The frequency band further solves the problem of harmonic interference.

Optionally, the first working frequency band and the second working frequency band are working frequency bands in the carrier aggregation mode in the embodiment of the present invention (that is, frequency bands in the CA combined frequency band).

It should be noted that, in the embodiment of the present invention, the working frequency band in the second frequency point information, that is, the second working frequency band, is higher than the working frequency band in the first frequency point information, that is, the first working frequency band. When the second working frequency band is specifically selected to transmit the first data, the harmonic interference is no longer generated.

It can be understood that, in the embodiment of the present invention, the harmonic interference refers to when the working frequency band of the harmonic generated when the uplink data is transmitted in the working frequency band used by the user equipment falls within the working frequency band used when the user equipment transmits the downlink data. Interfering with receiving downlink data from the user equipment. For the user equipment, when receiving the downlink data, the user equipment receives the harmonics of the uplink data transmitted by the user equipment, which has a great influence on the communication of the user equipment. Therefore, to solve this problem, the uplink data should be transmitted. The working frequency band is configured in the high frequency band. In the user equipment, the primary radio frequency chip supports the transmission of uplink data and downlink data, and the secondary radio frequency chip supports the transmission of the downlink data. Therefore, in the case of harmonic interference, the configuration of the primary frequency chip in the user equipment is configured. The frequency band is in the high frequency band of the CA combined frequency band, and the corresponding working frequency band of the auxiliary RF chip is configured in the low frequency band, which can solve the harmonic interference situation.

It should be noted that, since the scenario implemented in the embodiment of the present invention is a low-high frequency carrier aggregation and a harmonic interference problem, when there is harmonic interference, the uplink data is transmitted. When the working frequency band is configured as the high frequency band, the downlink data of the interfered other party transmits the low frequency band part of the low-high frequency carrier aggregation.

Specifically, when the type of the first data is uplink data, and the first data is transmitted to generate interference, the working frequency band of the uplink data transmitted in the primary radio frequency chip is specifically configured as a high frequency band.

Exemplarily, the first working frequency band is 800 MHz-1000 MHz, and the first working frequency point is 900 MHz, and the first data is uplink data. If the uplink data recorded in the code table is in the 800 MHz-1000 MHz, the corresponding interference frequency is 900 MHz. The user equipment can update a certain working frequency point on the second working frequency band 2000MHz-3000MHz.

Further, after the user equipment updates the second working frequency band configured to transmit data, the user equipment may transmit the first data in the second working frequency point on the second working frequency band.

S204: When the first working frequency point is a non-interference frequency point, the user equipment transmits the first working frequency point that the first data is still disposed on the first working frequency band.

After the user equipment determines whether the first working frequency point of transmitting the first data is an interference frequency point, when no interference occurs, the user equipment may not change the frequency information of the original configuration for transmitting the first data, that is, the first working frequency. When the point is a non-interfering frequency point, the user equipment transmits the first working frequency point where the first data is still configured in the first working frequency band.

Further, after the user equipment is configured to transmit the first working frequency band of the data, the user equipment may transmit the first data at the first working frequency point on the first working frequency band of the first frequency point information.

For example, suppose the first working frequency band is 800MHz-1000MHz, and the first working frequency point is At 980MHz, the first data is uplink data. If the uplink data recorded in the code table corresponds to an interference frequency of 900MHz in 800MHz-1000MHz, the user equipment can still be configured at 980MHz on 800MHz-1000MHz.

It can be understood that the method for resolving interference provided by the embodiment of the present invention can flexibly configure the working frequency band of the main and auxiliary radio frequency chips by comparing the pre-stored code table, avoiding the interference caused by the harmonics, and solving the harmonic mutual interference in the carrier aggregation. problem. At the same time, since the interference of various harmonics can be filtered out without setting a special filter, the number of filters and the limitation of the selection of the antenna switching device are saved, and the cost and the PCB layout area are reduced.

It should be noted that S203 and S204 in the embodiment of the present invention are the selection steps after S202, and one step is selected according to the actual detection situation; that is, in the embodiment of the present invention, after S202, S203 may also be executed. S204 may be performed, and the specific execution sequence may be determined according to an actual situation, and is not limited in the embodiment of the present invention; and after the execution of S203 or S204, the current processing flow ends.

The method for resolving interference provided by the embodiment of the present invention obtains the first frequency point information and the type of the first data configured when the first data is transmitted in the carrier aggregation mode; and according to the first frequency point information and the first data Type, determining whether interference occurs when transmitting the first data; when generating interference, configuring the first data update to be the second frequency point information, where the working frequency band in the second frequency point information is larger than the working frequency band in the first frequency point information Preferably, the first frequency point information and the second frequency point information are frequency point information in a carrier aggregation mode. With the above technical implementation, in the case of harmonic interference, the user equipment reconfigures the interference frequency used for transmitting the uplink data in the high frequency band in the carrier aggregation mode, so as to transmit the corresponding affected downlink data. In the low frequency band in the same carrier aggregation mode, the working frequency band of the harmonic generated during the uplink data transmission is far away from the working frequency band of the affected downlink data, thereby solving the problem of harmonic interference.
