Technical field

The embodiments of the present application relate to, but are not limited to, the field of wireless communication, and in particular, to a method for determining interference between terminals, a terminal, a base station, and a computer-readable storage medium.

Background technique

Spectrum resources are very precious resources. Each operator can only obtain spectrum resources with limited bandwidth. In order to maximize the utilization of spectrum resources, co-frequency networking will be widely adopted in networking. However, co-frequency networking will There is a serious interference problem. In order to solve this interference problem, the widely used methods to reduce interference include interference resource avoidance and interference suppression. Among them, interference resource avoidance is mainly used when serious interference may occur between terminals. The resources of adjacent base stations are staggered to avoid interference. Therefore, the anti-interference effect of this method is mainly reflected in the accuracy of judging that there may be severe interference between terminals.

However, the existing method for determining interference between terminals only determines whether there is interference between terminals in adjacent cells by determining the distance of the terminal relative to the own cell. For example, as shown in Figure 1, the first terminal is at a far point in the first cell, and the second terminal is at a far point in the second cell. Then, according to the existing inter-terminal interference determination method, it will be determined that the first terminal and the second terminal are in phase. Interference may occur in adjacent coverage areas, so the two cells will correspondingly stagger the resource allocation for the first terminal and the second terminal as much as possible to reduce interference. However, the accuracy of this method of judging whether there is interference between terminals in neighboring cells only by the distance of the terminal relative to the cell is not high, and it is easy to stagger the resources between the terminals with less interference in actual existence, resulting in resource occupation. Therefore, it is easy to cause interference avoidance between terminals with large actual interference by staggering resources.

Based on the above-mentioned system structure platform 100, various embodiments of the inter-terminal interference judgment method of the present application are proposed.

As shown in FIG. 3, FIG. 3 is a flowchart of an inter-terminal interference judgment method applied to a terminal according to an embodiment of the present application. The inter-terminal interference judgment method includes but is not limited to the following steps:

Step S110: Receive a radio resource control reconfiguration message sent by the base station.

In an embodiment, the radio resource control reconfiguration message includes the following configuration items: measurement configuration information (measConfig), mobility control information (MobilityControlInfo), non-access stratum dedicated information (dedicatedInfoNASList), radio resource configuration (radioResourceConfigDedicated), and handover Security configuration in the process (securityConfigHO).

In an embodiment, after the terminal receives the radio resource control reconfiguration message sent by the base station, the terminal sequentially performs the following actions according to the configuration items in the radio resource control reconfiguration message:

(1) If measurement configuration information is included, perform measurement configuration, which mainly includes the addition or modification or deletion of measurement objects, the addition or modification or deletion of measurement ID, the addition or modification or deletion of measurement report configuration, etc.;

(2) If it contains mobile control information, perform handover, mainly the terminal performs handover according to the handover command sent by the base station;

(3) If it contains non-access layer specific information, pass this field part to the upper layer;

(4) If it includes radio resource configuration, reconfigure the radio bearer, data radio bearer, transmission channel, and physical channel according to the content of the message;

(5) If the security configuration during the handover process is included, perform the handover;

If the above five items can be executed successfully, the terminal will send a radio resource control reconfiguration complete message to the base station to complete the radio resource control reconfiguration.

Step S120: Obtain the local beam measurement information corresponding to the local cell beam and the neighboring cell beam measurement information corresponding to the neighboring cell beam according to the measurement configuration information in the radio resource control reconfiguration message.

In an embodiment, the measurement configuration information in the radio resource control reconfiguration message includes content such as measurement object, measurement period, measurement threshold, and measurement event parameters. The terminal performs parameter measurement according to the content in the measurement configuration information. After the measurement is completed, the terminal will send relevant information to the base station for subsequent operation and processing by the base station. In addition, the measurement configuration information also includes the measurement A4 event. Specifically, when it is detected that the measurement result of the signal quality of the neighboring cell is better than the threshold value, the terminal will report the measurement result to the base station. In this embodiment, the measurement A4 event reported by the terminal can be used to facilitate the base station to determine whether it will interfere with other terminals. For example, when the terminal reports the measurement A4 event, it indicates that the signal quality of the neighboring cell is relatively good, so the terminal will have handover. Possibility of camping on the cell. In this case, the terminal is likely to interfere with neighboring cell terminals.

In an embodiment, when the terminal obtains the local area beam measurement information corresponding to the local cell beam and the adjacent cell beam measurement information corresponding to the adjacent cell beam, it can not only obtain the local area beam measurement information and the adjacent area beam measurement information, but also Obtain the frequency point of the beam of the current cell and the frequency point of the beam of the neighboring cell, so that the base station can find different measurement information corresponding to the same beam in subsequent operations, so as to determine whether there will be interference between the terminals.

In an embodiment, the beam measurement information in this area includes one or more of the following: reference signal reception power of the synchronization signal block, reference signal reception quality of the synchronization signal block, signal to interference plus noise ratio of the synchronization signal block, channel The reference signal received power of the status information reference signal, the reference signal received quality of the channel status information reference signal, and the signal to interference plus noise ratio of the channel status information reference signal. Correspondingly, the neighbor beam measurement information also includes one or more of the following: reference signal reception power of the synchronization signal block, reference signal reception quality of the synchronization signal block, signal to interference plus noise ratio of the synchronization signal block, and channel state information The reference signal received power of the reference signal, the reference signal received quality of the channel state information reference signal, and the signal to interference plus noise ratio of the channel state information reference signal. It is worth noting that the content of the beam measurement information in the local area corresponds to the content of the beam measurement information in the neighboring area.

Step S130: Send the local area beam measurement information and the neighboring area beam measurement information to the base station, so that the base station judges whether there is interference according to different measurement information corresponding to the same beam.

In an embodiment, when different terminals respectively send the measured local area beam measurement information and adjacent area beam measurement information to the base station, the base station may store local area beam measurement information and adjacent area beam measurement information corresponding to different terminals. Measurement information, and because different terminals may reside in different cells, the base station can store the measurement information of different beams corresponding to different cells, so that the base station can compare and judge according to different measurement information corresponding to the same beam. It is judged whether there is interference between the terminals, so that the high interference risk existing between the terminals can be judged more accurately, which facilitates more accurate implementation of interference avoidance and avoids resource occupation.

In addition, in another embodiment, when the local area beam measurement information and neighboring area beam measurement information are sent to the base station in step S130, the following conditions need to be met:

When the measurement event parameter reaches the measurement threshold, the local area beam measurement information and the adjacent area beam measurement information are sent to the base station according to the measurement period.

In one embodiment, the measurement event parameters are event parameters configured by the base station to perform measurements on the terminal, including the local area beam measurement information obtained when the terminal measures the beam of the current cell and the neighboring cell obtained when the terminal measures the beam of the adjacent cell. Beam measurement information. Therefore, when the measurement event parameters reach the measurement threshold, the terminal periodically sends the local area beam measurement information and neighboring area beam measurement information to the base station according to the measurement period in the measurement configuration information, so that the base station can be more accurate Perform subsequent interference judgment processing. In addition, the measurement threshold value is a condition for triggering the terminal to report the measurement. The specific value of the measurement threshold value can be appropriately selected according to actual use needs. For example, the measurement threshold value can be selected as -10dBm.

In one embodiment, since both the local beam measurement information and the neighbor beam measurement information include the reference signal reception power of the synchronization signal block, the reference signal reception quality of the synchronization signal block, the signal to interference plus noise ratio of the synchronization signal block, and the channel The reference signal received power of the status information reference signal, the reference signal received quality of the channel status information reference signal, and the signal to interference plus noise ratio of the channel status information reference signal are a combination of any one or more of them. Therefore, the measurement event parameter reaches the measurement The threshold has multiple implementations: In one implementation, it is assumed that both the local beam measurement information and the neighboring beam measurement information only include the reference signal received power of the synchronization signal block, if any one of the two reaches the measurement threshold Value, it can be considered that the measurement event parameter reaches the measurement threshold value, or when both reach the measurement threshold value, the measurement event parameter is considered to have reached the measurement threshold value. In another embodiment, it is assumed that both the local beam measurement information and the neighboring beam measurement information include the reference signal received power of the synchronization signal block and the reference signal received power of the channel state information reference signal. In this case, the measurement threshold There can be multiple values, which correspond to various parameter types in the beam measurement information of the local area and the beam measurement information of the neighboring area. For example, the measurement threshold includes the first measurement threshold of the reference signal received power corresponding to the synchronization signal block. And the second measurement threshold value of the reference signal received power corresponding to the channel state information reference signal. At this time, when the reference signal received power and channel state information of the synchronization signal block of the local beam measurement information or the neighboring beam measurement information are referenced When the reference signal received power of the signal reaches the first measurement threshold and the second measurement threshold respectively, it can be considered that the measurement event parameter reaches the measurement threshold, or when both the local beam measurement information and the adjacent beam measurement information When the reference signal received power of the synchronization signal block and the reference signal received power of the channel state information reference signal both correspond to the first measurement threshold and the second measurement threshold, it is considered that the measurement event parameter reaches the measurement threshold. In addition, other implementation manners in which the measurement event parameter reaches the measurement threshold, for example, when the local area beam measurement information and the neighboring area beam measurement information include other parameter types, the technical principles can refer to the foregoing implementation manners, and will not be repeated here.

In addition, in an embodiment, both the local cell beam and the neighboring cell beam are narrow beams. For a base station, the base station will configure multiple narrow beams. Correspondingly, the local beam measurement information and the neighboring beam measurement information are both narrow beams. Measurement information for narrow beams. By enabling the terminals in different cells to obtain the local beam measurement information corresponding to the narrow beam of the cell and the neighboring cell beam measurement information corresponding to the narrow beam of the neighboring cell, the base station uses different measurement information corresponding to the same narrow beam. Determine whether there is interference. Compared with the traditional method of judging whether there is interference based on a wide beam, this embodiment can more accurately judge the high interference risk existing between terminals, thereby being able to perform interference avoidance more accurately and avoid resource occupation.

Those skilled in the art can understand that the beam is obtained by beamforming. Specifically, beamforming generates a directional beam by adjusting the weighting coefficient of each element in the antenna array. The sexual beam is called the narrow beam.

As shown in FIG. 4, FIG. 4 is a flowchart of a method for determining interference between terminals applied to a base station according to another embodiment of the present application. The method for determining interference between terminals includes but not limited to the following steps:

Step S210: Send a radio resource control reconfiguration message to the terminal of the cell.

In an embodiment, the base station may send a radio resource control reconfiguration message to the terminal through the air interface, so that the terminal can periodically report measurement information, so that the base station can perform subsequent interference judgment processing based on the measurement information reported by the terminal.

In an embodiment, the radio resource control reconfiguration message includes the following configuration items: measurement configuration information, mobility control information, non-access stratum dedicated information, radio resource configuration, and security configuration during handover. Among them, the measurement configuration information includes the measurement object, the measurement period, the measurement threshold, and the measurement event parameters. When the terminal successfully executes the above configuration items, the terminal will send a radio resource control reconfiguration complete message to the base station. The radio resource control reconfiguration complete message may contain the local beam measurement information corresponding to the beam of the local cell and the beam measurement information corresponding to the neighboring cell. The neighboring cell beam measurement information of the beam can facilitate the base station to perform subsequent interference judgment processing.

Step S220: Receive the local beam measurement information corresponding to the beam of the local cell and the neighboring cell beam measurement information corresponding to the beam of the neighboring cell sent by the terminal of the local cell. The local beam measurement information and the neighboring beam measurement information are sent by the terminal of the local cell according to the radio resources. The measurement configuration information in the control reconfiguration message is obtained by measurement.

In one embodiment, when the base station receives the local beam measurement information corresponding to the beam of the local cell and the neighboring cell beam measurement information corresponding to the beam of the neighboring cell sent by the terminal of the local cell, it can not only receive the local beam measurement information and neighboring beam measurement information. The area beam measurement information can also receive the frequency of the beam of the current cell and the frequency of the beam of the neighboring cell, so that the frequency of the beam of the local cell and the frequency of the beam of the neighboring cell sent by different terminals can be found to have the same frequency. Frequency beam, and according to different measurement information corresponding to the beam with the same frequency point, it is determined whether there will be interference between the terminals.

Step S230: Receive the local beam measurement information of the local cell beam sent by the neighboring cell base station and acquired by the neighboring cell terminal, and judge whether there is interference according to different measurement information corresponding to the same beam.

In an embodiment, the base station of the local cell may receive the local beam measurement information corresponding to the beam of the local cell sent by the base station of the neighboring cell, and the local beam measurement information is obtained by the terminal of the neighboring cell. The cell base station can obtain different measurement information corresponding to the same beam by combining the local beam measurement information corresponding to the beam of the local cell acquired by the terminal of the local cell, for example, the terminal corresponding to the local cell obtained by the terminal of the local cell and the terminal of the neighboring cell. The measurement information of a beam. At this time, the base station of the cell can judge whether there is interference between the terminal of the cell and the terminal of the neighboring cell according to the different measurement information corresponding to the same beam. For example, if the value of the measurement information of the cell terminal is If the value of the measurement information of the neighboring cell terminal is close to that of the neighboring cell terminal, it means that the neighboring cell terminal will cause serious interference to the terminal of the cell, so interference avoidance needs to be performed; if the value of the measurement information of the terminal of the cell is equal to that of the neighboring cell terminal If the numerical difference is large, it means that the neighboring cell terminal will not cause interference to the cell terminal or only weak interference, so there is no need to perform interference avoidance. Therefore, by summarizing different measurement information corresponding to the same beam obtained by different terminals between base stations, and performing judgment processing based on different measurement information corresponding to the same beam, it is possible to more accurately determine whether there is a risk of interference between terminals. This can facilitate more accurate execution of interference avoidance.

In addition, in some embodiments, the method for determining interference between terminals applied to a base station may further include step S240. This step S240 and step S230 in the embodiment shown in FIG. 4 may be parallel steps or synchronized steps. step. When step S240 and step S230 in the embodiment shown in FIG. 4 are parallel steps, the inter-terminal interference judgment method applied to the base station only performs step S240 or step S230; when step S240 and the embodiment shown in FIG. 4 When step S230 in is a synchronization step, the method for determining interference between terminals applied to a base station simultaneously executes step S240 and step S230. Specifically, this step S240 is:

In step S240, the neighboring cell beam measurement information is sent to the neighboring cell base station, so that the neighboring cell base station judges whether there is interference according to different measurement information corresponding to the same beam.

In an embodiment, the base station of this cell can only play the role of receiving and forwarding the neighboring cell beam measurement information obtained by the terminal of the cell. When the base station of the neighboring cell receives the neighboring cell terminal forwarded by the base station of the cell corresponding to the neighboring cell terminal. In the case of cell beam measurement information, the neighboring cell base station can check whether there is interference between the terminals according to the measurement information of the neighboring cell base station reported by the terminal in its cell and the neighboring cell beam measurement information corresponding to the terminal of the cell. More accurate judgment processing can facilitate the more accurate execution of interference avoidance. In addition, the base station of this cell can also forward the neighboring cell beam measurement information and the local beam measurement information obtained by the terminal of the cell at the same time. When the neighboring cell base station combines the neighboring cell beam measurement information of the terminals corresponding to different cells with the local beam measurement When the information is aggregated and processed, the richness and accuracy of the data can be guaranteed, so as to provide a data basis for the subsequent more accurate implementation of interference avoidance.

In addition, in an embodiment, step S230 includes but is not limited to the following steps:

Step S231, receiving the local beam measurement information of the local cell beam sent by the neighboring cell base station and acquired by the neighboring cell terminal;

Step S232: Determine the local beam measurement information of the neighbor cell terminal corresponding to the same beam and the local beam measurement information of the local cell terminal according to the local cell beam acquired by the neighboring cell terminal and the local cell beam acquired by the local cell terminal , Get the inter-terminal interference measurement value corresponding to the same beam;

Step S233: When the measured value of the inter-terminal interference is not greater than the interference threshold, it is determined that there is interference between the terminal of the current cell and the terminal of the neighboring cell.

In an embodiment, the determination of the local beam measurement information of the neighboring cell terminal corresponding to the same beam and the local beam measurement information of the local cell terminal in step S232 may have different implementation manners. For example, the base station of the cell may first save the beam measurement information of the cell corresponding to the beam of the cell obtained by the terminal of the cell. When the base station of the cell receives the beam measurement information of the cell corresponding to the beam of the cell obtained by the terminal of the neighboring cell At this time, the base station of the cell can compare the beams of the cell corresponding to the neighboring cell terminal with the beams of the cell corresponding to the cell terminal, so as to determine the beam measurement information and the local beam measurement information of the neighboring cell terminal corresponding to the same beam. The local beam measurement information of the cell terminal. For another example, the base station of this cell may mark the beam of the cell corresponding to the terminal of the cell with the first mark set, and mark the beam of the cell corresponding to the terminal of the neighboring cell with the second mark set, and then the base station of the cell compares the first mark set In the second marker set, the same markers represent the same beams. Therefore, the base station of the cell screens out the beams of the cell with the same markers to determine the beam measurement information and beam measurement information of neighboring cell terminals corresponding to the same beam. The local beam measurement information of the local cell terminal.

In an embodiment, the inter-terminal interference measurement value may have multiple different implementations. For example, the inter-terminal interference measurement value can be the parameter difference between the local beam measurement information corresponding to the neighboring cell terminal and the local beam measurement information corresponding to the local cell terminal. Specifically, it is assumed that the local beam measurement information is synchronized The reference signal received power of the signal block, then, the reference signal received power of the synchronization signal block corresponding to the beam of the cell obtained by the terminal of the own cell, and the reference signal block of the synchronization signal block corresponding to the beam of the current cell obtained by the terminal of the neighboring cell The difference between the signal received power is the measured value of inter-terminal interference. For another example, the inter-terminal interference measurement value may be the variance value between the local beam measurement information corresponding to the neighboring cell terminal and the local beam measurement information corresponding to the local cell terminal. Specifically, it is assumed that the local beam measurement information is The signal to interference plus noise ratio of the synchronization signal block, then the signal to interference plus noise ratio of the synchronization signal block corresponding to the beam of the cell obtained by the terminal of the cell corresponds to the ratio of the signal to interference plus noise obtained by the terminals of other neighboring cells. The difference between the received power of the reference signal of the synchronization signal block of the beam is the measured value of inter-terminal interference.

In an embodiment, the interference threshold is a criterion for judging whether there is interference between terminals. The specific value of the interference threshold can be appropriately selected according to actual use needs. For example, when the interference measurement value between terminals is different In the case of the parameter difference between the information, the interference threshold can be selected as 2dBm or 3dBm.

In one embodiment, the local beam measurement information of the neighboring cell terminal corresponding to the same beam and the local beam measurement information of the local cell terminal are determined based on the local cell beam acquired by the neighboring cell terminal and the local cell beam acquired by the local cell terminal. Beam measurement information in this area, and the obtained inter-terminal interference measurement value corresponding to the same beam is compared with the preset interference threshold, so that it can be more accurately judged whether there is interference between the terminals. For example, when the measured value of inter-terminal interference is less than or equal to the interference threshold, it can be considered that the distance between the terminals is relatively close, and there is a risk of high interference. When the measured value of inter-terminal interference is greater than the interference threshold, it can be considered It is believed that the distance between terminals is relatively long, and there is no risk of high interference. Therefore, in this embodiment, by comparing the magnitude of the interference measurement value between the terminals and the interference threshold value, it can be more accurately determined whether there is interference between the terminals, which can facilitate the more accurate implementation of interference avoidance.

The following is an exemplary description:

Referring to FIG. 5, FIG. 5 is a schematic diagram of a network architecture for performing a method for determining interference between terminals in another embodiment. As shown in Figure 5, the base station gNB1 in this cell covers the first local cell beam A1 and the second local cell beam A2, and the neighboring cell base station gNB2 covers the first neighboring cell beam B1 and the second neighboring cell. Cell beam B2; the cell terminal U1 resides in the first cell beam A1, and the cell terminal U1 can receive the signal of the first neighbor cell beam B1, and the neighbor cell terminal U2 camps on the first neighbor cell beam B1 , And the neighboring cell terminal U2 can receive the signal of the first local cell beam A1. The base station gNB1 of the cell can send a radio resource control reconfiguration message to the cell terminal U1 through the air interface, and the cell terminal U1 can obtain the synchronization corresponding to the first local cell beam A1 according to the measurement configuration information in the radio resource control reconfiguration message.

Then, the terminal U1 of the own cell receives the acquired reference signal of the synchronization signal block corresponding to the two beams The power is reported to the base station gNB1 of the cell; the base station gNB2 of the neighboring cell can send a radio resource control reconfiguration message to the neighboring cell terminal U2 through the air interface, and the neighboring cell terminal U2 obtains it separately according to the measurement configuration information in the radio resource control reconfiguration message The reference signal received power of the synchronization signal block corresponding to the first neighboring cell beam B1 and the reference signal received power of the synchronization signal block corresponding to the first local cell beam A1. Then, the neighboring cell terminal U2 corresponds to the two The reference signal received power of the synchronization signal block of the two beams is reported to the neighboring cell base station gNB2; then, the neighboring cell base station gNB2 can obtain the reference signal received power of the synchronization signal block corresponding to the two beams obtained by the neighboring cell terminal U2, It is delivered to the base station gNB1 of the cell through the Xn interface between the base stations in the form of interactive measurement messages. Specifically, the interactive measurement message may include messages and fields such as information type and terminal measurement result list information. Among them, terminal measurement result list information It can include the frequency point of the measurement object, the measurement period, the received power of the reference signal, the received quality of the reference signal, and the signal-to-interference plus noise ratio. Therefore, the base station gNB1 of the cell can summarize the reference signal received power of the synchronization signal blocks corresponding to the two beams obtained by the cell terminal U1 and the synchronization signal blocks corresponding to the two beams obtained by the neighboring cell terminal U2. At this time, the base station gNB1 of the cell finds the reference signal received power of the synchronization signal block corresponding to the first cell beam A1 obtained by the cell terminal U1 and the reference signal received power obtained by the neighboring cell terminal U2 corresponding to The reference signal received power of the synchronization signal block of the first local cell beam A1, and the judgment is made according to the reference signal received power of the two synchronization signal blocks to determine whether there is interference between the terminal U1 of the current cell and the terminal U2 of the neighboring cell, for example , The base station gNB1 of this cell calculates the difference between the received power of the reference signal of the two synchronization signal blocks. If the difference is less than or equal to the interference threshold, for example, the interference threshold is 3dBm, it can be considered as the terminal of the cell. The location distance between U1 and the neighboring cell terminal U2 is relatively close, and there is a risk of high interference; if the difference is greater than the interference threshold, for example, the interference threshold is 3dBm, then the cell terminal U1 and the neighboring cell can be considered The location distance between cell terminals U2 is relatively long, and there is no risk of high interference.
