Description

Inter-terminal interference judgment method, terminal, base station and storage medium

Technical Field

The present disclosure relates to, but not limited to, the field of wireless communications, and in particular, to a method for determining interference between terminals, a terminal, a base station, and a computer-readable storage medium.

Background

The method for reducing the interference is characterized in that the interference resource avoidance and interference suppression are carried out by staggering the resources of adjacent base stations through scheduling when the serious interference possibly occurs between the terminals, so the anti-interference effect of the method is mainly embodied in the accuracy of judging the serious interference possibly existing between the terminals.

However, the conventional inter-terminal interference determination method determines whether or not there is interference between terminals of adjacent cells only by determining the distance of the terminal with respect to the cell. For example, as shown in fig. 1, if a first terminal is at a far point of a first cell and a second terminal is at a far point of a second cell, it is determined that the first terminal and the second terminal may generate interference in adjacent coverage areas according to a conventional inter-terminal interference determination method, and therefore, the two cells correspondingly stagger resource allocation between the first terminal and the second terminal as much as possible to reduce interference. However, the method for determining whether or not there is interference between terminals in adjacent cells only by the distance between the terminal and the cell is not accurate, and resource is likely to be staggered between terminals with actually small interference, which causes resource occupation, and thus terminals with actually large interference cannot avoid interference by resource staggering.

Based on the system architecture platform 100, embodiments of the inter-terminal interference determination method according to the present application are provided.

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

step S110 is to receive a radio resource control reconfiguration message transmitted by the base station.

In one embodiment, the rrc reconfiguration message includes the following configuration items: measurement configuration information (measConfig), mobility control information (MobilityControlInfo), non-access stratum specific information (dedicatedinfonaslst), radio resource configuration (radioResourceConfigDedicated), and security configuration during handover (securityconfho).

In an embodiment, after the terminal receives the rrc reconfiguration message sent by the base station, the terminal performs the following actions according to the configuration item sequence in the rrc reconfiguration message:

(1) if the measurement configuration information is contained, executing measurement configuration, mainly including addition or modification or deletion of a measurement object, addition or modification or deletion of a measurement ID, addition or modification or deletion of measurement report configuration and the like;

(2) if the mobile terminal contains the mobile control information, switching is executed, and the terminal mainly performs switching according to a switching command sent by the base station;

(3) if the field part contains the non-access stratum special information, the field part is transmitted to an upper layer;

(4) if the radio resource allocation is contained, the radio bearer, the data radio bearer, the transmission channel and the physical channel are reconfigured according to the message content;

(5) if the security configuration in the switching process is included, switching is executed;

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

Step S120, obtaining the local area beam measurement information corresponding to the local area beam and the adjacent area beam measurement information corresponding to the adjacent area beam according to the measurement configuration information in the radio resource control reconfiguration message.

In an embodiment, the measurement configuration information in the rrc reconfiguration message includes contents such as a measurement object, a measurement period, a measurement threshold, and a measurement event parameter, and the terminal performs parameter measurement according to the contents in the measurement configuration information, and after the measurement is completed, the terminal sends related information to the base station for the base station to perform subsequent operation processing. In addition, the measurement configuration information further includes a 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 reports the measurement result to the base station. In this embodiment, the measurement a4 event reported by the terminal may be utilized, so that the base station can determine whether to 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 good, and therefore the terminal may have a possibility of switching the camping cell, and in this case, the terminal is likely to generate a situation of interfering with the terminal of the neighboring cell.

In an embodiment, when the terminal acquires the local cell beam measurement information corresponding to the local cell beam and the neighboring cell beam measurement information corresponding to the neighboring cell beam, the terminal can acquire not only the local cell beam measurement information and the neighboring cell beam measurement information, but also the frequency point of the local cell beam and the frequency point of the neighboring cell beam, so that the base station can conveniently search different measurement information corresponding to the same beam in subsequent operations, and can conveniently judge whether interference exists between the terminals.

In one embodiment, the local area beam measurement information includes one or more of the following: reference signal received power of the synchronization signal block, reference signal received quality of the synchronization signal block, signal to interference plus noise ratio of the synchronization signal block, reference signal received power of the channel state information reference signal, reference signal received quality of the channel state information reference signal, and signal to interference plus noise ratio of the channel state information reference signal. Correspondingly, the neighbor cell beam measurement information also includes one or more of the following: reference signal received power of the synchronization signal block, reference signal received quality of the synchronization signal block, signal to interference plus noise ratio of the synchronization signal block, reference signal received power of the channel state information reference signal, reference signal received quality of the channel state information reference signal, and signal to interference plus noise ratio of the channel state information reference signal. It should be noted that the content of the local area beam measurement information is consistent with the content of the neighboring area beam measurement information.

Step S130, the local area beam measurement information and the adjacent area beam measurement information are sent to the base station, so that the base station judges whether interference exists according to different measurement information corresponding to the same beam.

In an embodiment, after different terminals respectively send the measured local beam measurement information and the measured neighboring beam measurement information to the base station, the base station may store the local beam measurement information and the neighboring beam measurement information corresponding to the different terminals, and since the cells in which the different terminals may reside are different, the base station may store the measurement information of different beams corresponding to different cells, so that the base station may perform a comparison determination according to the different measurement information corresponding to the same beam, thereby determining whether there is interference between the terminals, thereby more accurately determining a high interference risk between the terminals, facilitating a more accurate execution of interference avoidance, and avoiding resource occupation.

In addition, in another embodiment, when the local area beam measurement information and the neighboring area beam measurement information are transmitted to the base station in step S130, the following condition needs to be satisfied:

and when the measurement event parameter reaches the measurement threshold value, sending the local area beam measurement information and the adjacent area beam measurement information to the base station according to the measurement period.

In an embodiment, the measurement event parameter is an event parameter for the base station to configure the terminal to perform measurement, where the event parameter includes local beam measurement information obtained when the terminal measures a local beam and neighboring beam measurement information obtained when the terminal measures a neighboring beam, and therefore, when the measurement event parameter reaches a measurement threshold, the terminal periodically sends the local beam measurement information and the neighboring beam measurement information to the base station according to a measurement period in the measurement configuration information, so that the base station can perform subsequent interference determination processing more accurately. In addition, the measurement threshold is a condition for triggering the terminal to report measurement, and a specific value of the measurement threshold may be appropriately selected according to actual use requirements, for example, the measurement threshold may be selected to be-10 dBm.

In an embodiment, since the local beam measurement information and the neighboring beam measurement information each include any one or a combination of more of reference signal received power of a synchronization signal block, reference signal received quality of the synchronization signal block, signal to interference plus noise ratio of the synchronization signal block, reference signal received power of a channel state information reference signal, reference signal received quality of the channel state information reference signal, and signal to interference plus noise ratio of the channel state information reference signal, there are multiple embodiments for the measurement event parameter reaching the measurement threshold value: in one embodiment, it is assumed that both the local beam measurement information and the neighboring beam measurement information include only the reference signal received power of the synchronization signal block, and if either one of the local beam measurement information and the neighboring beam measurement information reaches the measurement threshold, it is determined that the measurement event parameter reaches the measurement threshold, or, when both of the local beam measurement information and the neighboring beam measurement information reach the measurement threshold, it is determined that the measurement event parameter reaches the measurement threshold. In another embodiment, it is assumed that the local beam measurement information and the neighboring beam measurement information both include reference signal received power of a synchronization signal block and reference signal received power of a channel state information reference signal, in this case, there may be a plurality of measurement thresholds respectively corresponding to respective parameter types in the local beam measurement information and the neighboring beam measurement information, for example, the measurement thresholds include a first measurement threshold corresponding to the reference signal received power of the synchronization signal block and a second measurement threshold corresponding to the reference signal received power of the channel state information reference signal, when the reference signal received power of the synchronization signal block and the reference signal received power of the channel state information reference signal of the local beam measurement information or the neighboring beam measurement information respectively reach the first measurement threshold and the second measurement threshold, the measurement event parameter may be considered to reach the measurement threshold, or, when the reference signal received power of the synchronization signal block of the local beam measurement information and the reference signal received power of the channel state information reference signal of the neighboring beam measurement information both correspondingly reach the first measurement threshold and the second measurement threshold, the measurement event parameter may be considered to reach the measurement threshold. In addition, in other embodiments where the measurement event parameter reaches the measurement threshold value, for example, when the local area beam measurement information and the neighboring area beam measurement information include other parameter types, the technical principle of the embodiment may refer to the above embodiments, and details are not repeated herein.

In addition, in an embodiment, the cell beam and the neighbor cell beam are both narrow beams, and for one base station, the base station configures a plurality of narrow beams, and correspondingly, the cell beam measurement information and the neighbor cell beam measurement information are both measurement information for the narrow beams. By enabling terminals in different cells to respectively acquire local cell beam measurement information corresponding to a narrow beam of the local cell and adjacent cell beam measurement information corresponding to a narrow beam of an adjacent cell, a base station judges whether interference exists according to different measurement information corresponding to the same narrow beam. Compared with the traditional method for judging whether interference exists according to the wide beam, the method can judge the high interference risk existing between the terminals more accurately, thereby being capable of executing interference avoidance more accurately and avoiding resource occupation.

It will be understood by those skilled in the art that the beam is obtained by beam forming, and specifically, the beam forming generates a directional beam by adjusting a weighting coefficient of each array element in the antenna array, and generally, such a directional beam is referred to as a narrow beam.

As shown in fig. 4, fig. 4 is a flowchart of a method for determining inter-terminal interference applied to a base station according to another embodiment of the present application, where the method for determining inter-terminal interference includes, but is not limited to, the following steps:

step S210, sending the radio resource control reconfiguration message to the terminal of the local cell.

In an embodiment, the base station may send the rrc reconfiguration message to the terminal over an air interface, so that the terminal can periodically report the measurement information, so that the base station can perform subsequent interference determination processing according to the measurement information reported by the terminal.

In one embodiment, the rrc reconfiguration message includes the following configuration items: measurement configuration information, mobility control information, non-access stratum specific information, radio resource configuration, and security configuration during handover. The measurement configuration information includes contents such as a measurement object, a measurement period, a measurement threshold value, and a measurement event parameter. After the terminal successfully executes the configuration items, the terminal sends a radio resource control reconfiguration complete message to the base station, and the radio resource control reconfiguration complete message may include the own cell beam measurement information corresponding to the own cell beam and the neighboring cell beam measurement information corresponding to the neighboring cell beam, so that the base station can conveniently execute subsequent interference judgment processing.

Step S220 is to receive the local area beam measurement information corresponding to the local area beam and the neighboring area beam measurement information corresponding to the neighboring area beam, which are sent by the terminal of the local area, where the local area beam measurement information and the neighboring area beam measurement information are obtained by the terminal of the local area according to the measurement configuration information in the radio resource control reconfiguration message.

In an embodiment, when receiving the local cell beam measurement information corresponding to the local cell beam and the neighboring cell beam measurement information corresponding to the neighboring cell beam sent by the local cell terminal, the base station can receive not only the local cell beam measurement information and the neighboring cell beam measurement information, but also the frequency point of the local cell beam and the frequency point of the neighboring cell beam, so as to find out the beam with the same frequency point according to the frequency point of the local cell beam and the frequency point of the neighboring cell beam sent by different terminals, and determine whether there is interference between the terminals according to different measurement information corresponding to the beam with the same frequency point.

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

In an embodiment, the local cell base station may receive local cell beam measurement information corresponding to a local cell beam sent by an adjacent cell base station, and the local cell beam measurement information is obtained by an adjacent cell terminal, at this time, the local cell base station may obtain different measurement information corresponding to the same beam by combining the local cell beam measurement information corresponding to the local cell beam obtained by the local cell terminal, for example, measurement information corresponding to one beam of the local cell obtained by the local cell terminal and the adjacent cell terminal, at this time, the local cell base station may determine whether there is interference between the local cell terminal and the adjacent cell terminal according to the different measurement information corresponding to the same beam, for example, if the value of the measurement information of the local cell terminal is closer to the value of the measurement information of the adjacent cell terminal, it indicates that the adjacent cell terminal may generate more serious interference to the local cell terminal, interference avoidance needs to be performed; if the difference between the value of the measurement information of the terminal in the cell and the value of the measurement information of the terminal in the neighboring cell is large, it indicates that the terminal in the neighboring cell does not generate interference to the terminal in the cell or only generates weak interference, so that interference avoidance does not need to be executed. Therefore, by summarizing different measurement information corresponding to the same beam acquired by different terminals between base stations and performing judgment processing according to the different measurement information corresponding to the same beam, whether interference risks exist between the terminals can be judged more accurately, and more accurate execution of interference avoidance can be facilitated.

In addition, in some embodiments, the method for determining interference between terminals applied to the base station may further include step S240, where step S240 and step S230 in the embodiment shown in fig. 4 may be parallel steps or may be synchronous steps. When step S240 and step S230 in the embodiment shown in fig. 4 are parallel steps, the method for determining interference between terminals applied to a base station only performs step S240 or step S230; when step S240 and step S230 in the embodiment shown in fig. 4 are synchronous steps, the inter-terminal interference determination method applied to the base station performs step S240 and step S230 at the same time. Specifically, the step S240 is:

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

In an embodiment, the local cell base station may only play a role in receiving and forwarding the neighboring cell beam measurement information acquired by the local cell terminal, and when the neighboring cell base station receives the neighboring cell beam measurement information corresponding to the local cell terminal forwarded by the local cell base station, the neighboring cell base station may perform more accurate determination processing on whether there is interference between terminals according to the measurement information of the beam corresponding to the neighboring cell base station and the neighboring cell beam measurement information corresponding to the local cell terminal, which are reported by the terminals in its cell, so that more accurate execution of interference avoidance may be facilitated. In addition, the cell base station can also simultaneously forward the adjacent cell beam measurement information and the cell beam measurement information acquired by the cell terminal, and when the adjacent cell base station collects the adjacent cell beam measurement information and the cell beam measurement information of the terminals corresponding to different cells, the richness and accuracy of data can be ensured, so that a data basis can be provided for the follow-up accurate interference avoidance execution.

Additionally, in one embodiment, step S230 includes, but is not limited to, the following steps:

step S231, receiving the local area beam measurement information of the local area beam sent by the adjacent area base station and acquired by the adjacent area terminal;

step S232, according to the wave beam of the local cell acquired by the terminal of the adjacent cell and the wave beam of the local cell acquired by the terminal of the local cell, the wave beam measurement information of the local cell and the wave beam measurement information of the local cell corresponding to the terminal of the adjacent cell of the same wave beam are determined, and the interference measurement value between the terminals corresponding to the same wave beam is obtained;

step S233, when the interference measured value between the terminals is not larger than the interference threshold value, the interference between the terminal of the local cell and the terminal of the adjacent cell is determined.

In an embodiment, the determination in step S232 may be implemented differently for the local area beam measurement information of the neighboring cell terminal corresponding to the same beam and the local area beam measurement information of the local cell terminal. For example, the cell base station may store the cell beam measurement information corresponding to the cell beam acquired by the cell terminal, and when the cell base station receives the cell beam measurement information corresponding to the cell beam acquired by the cell terminal, the cell base station may compare the cell beam corresponding to the cell terminal with the cell beam corresponding to the cell terminal one by one, thereby determining the cell beam measurement information corresponding to the cell terminal having the same beam and the cell beam measurement information corresponding to the cell terminal. For another example, the cell base station may mark the cell beam corresponding to the cell terminal with a first mark set, and mark the cell beam corresponding to the neighboring cell terminal with a second mark set, and then compare the first mark set with the second mark set, where the same mark represents the same beam, so that the cell base station screens out the cell beam with the same mark, and can determine the cell beam measurement information of the neighboring cell terminal corresponding to the same beam and the cell beam measurement information of the cell terminal.

In one embodiment, the inter-terminal interference measurement may be implemented in a variety of different ways. For example, the inter-terminal interference measurement value may be a parameter difference between the local area beam measurement information corresponding to the neighboring cell terminal and the local area beam measurement information corresponding to the local cell terminal, and specifically, assuming that the local area beam measurement information is the reference signal received power of the synchronization signal block, a difference between the reference signal received power of the synchronization signal block corresponding to the local cell beam acquired by the local cell terminal and the reference signal received power of the synchronization signal block corresponding to the local cell beam acquired by the neighboring cell terminal is the inter-terminal interference measurement value. For another example, the inter-terminal interference measurement value may be a 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, and specifically, assuming that the local beam measurement information is a signal-to-interference-plus-noise ratio of the synchronization signal block, a difference value between the signal-to-interference-plus-noise ratio of the synchronization signal block corresponding to the local cell beam acquired by the local cell terminal and the reference signal reception power of the synchronization signal block corresponding to the local cell beam acquired by the other neighboring cell terminals is the inter-terminal interference measurement value.

In an embodiment, the interference threshold is a criterion for determining whether there is interference between terminals, and a specific value of the interference threshold may be appropriately selected according to actual usage requirements, for example, when the inter-terminal interference measurement value is a parameter difference between different pieces of measurement information, the interference threshold may be selected to be 2dBm or 3 dBm.

In an embodiment, the cell beam measurement information of the neighboring cell terminal corresponding to the same beam and the cell beam measurement information of the local cell terminal are determined according to the cell beam acquired by the neighboring cell terminal and the cell beam acquired by the local cell terminal, and the inter-terminal interference measurement value corresponding to the same beam obtained by the determining is compared with a preset interference threshold value, so that whether interference exists between the terminals can be determined more accurately. For example, when the inter-terminal interference measurement value is smaller than or equal to the interference threshold value, it may be considered that the distance between the terminals is short and there is a risk of high interference, and when the inter-terminal interference measurement value is greater than the interference threshold value, it may be considered that the distance between the terminals is 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 with the magnitude of the interference threshold value, whether interference exists between the terminals can be accurately determined, so that accurate execution of interference avoidance can be facilitated.

The following are exemplary illustrations:

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 fig. 5, the local cell base station gNB1 covers a first local cell beam a1 and a second local cell beam a2 in the local cell, and the neighboring cell base station gNB2 covers a first neighboring cell beam B1 and a second neighboring cell beam B2 in the neighboring cell; terminal U1 resides in first local cell beam a1, and terminal U1 receives the signal of first neighboring cell beam B1, while terminal U2 resides in first neighboring cell beam B1, and terminal U2 receives the signal of first local cell beam a 1. The local cell base station gNB1 can send a radio resource control reconfiguration message to the local cell terminal U1 through an air interface, the local cell terminal U1 respectively acquires the reference signal receiving power of a synchronization signal block corresponding to a first local cell beam A1 and the reference signal receiving power of a synchronization signal block corresponding to a first neighboring cell beam B1 according to the measurement configuration information in the radio resource control reconfiguration message, and then the local cell terminal U1 reports the acquired reference signal receiving power of the synchronization signal block corresponding to the two beams to the local cell base station gNB 1; the neighbor cell base station gNB2 may send a rrc reconfiguration message to the neighbor cell terminal U2 via an air interface, the neighbor cell terminal U2 obtains the reference signal received power of the synchronization signal block corresponding to the first neighbor cell beam B1 and the reference signal received power of the synchronization signal block corresponding to the first cell beam a1 according to the measurement configuration information in the rrc reconfiguration message, and then the neighbor cell terminal U2 reports the obtained reference signal received powers of the synchronization signal blocks corresponding to the two beams to the neighbor cell base station gNB 2; then, the neighboring cell nodeb 2 may transmit the reference signal received power of the synchronization signal block corresponding to the two beams acquired by the neighboring cell terminal U2 to the local cell nodeb gNB1 through an Xn interface between the base stations in the form of an interactive measurement message, specifically, the interactive measurement message may include information and fields such as an information type and terminal measurement result list information, where the terminal measurement result list information may include contents such as a measurement object frequency point, a measurement period, a reference signal received power, a reference signal received quality, and a signal-to-interference-plus-noise ratio. Therefore, the local cell base station gNB1 may collect the reference signal received powers of the synchronization signal blocks corresponding to the two beams acquired by the local cell terminal U1 and the reference signal received powers of the synchronization signal blocks corresponding to the two beams acquired by the neighboring cell terminal U2, at this time, the local cell base station gNB1 finds the reference signal received power of the synchronization signal block corresponding to the first local cell beam a1 acquired by the local cell terminal U1 and the reference signal received power of the synchronization signal block corresponding to the first local cell beam a1 acquired by the neighboring cell terminal U2, and makes a judgment according to the reference signal received powers of the two synchronization signal blocks to determine whether there is interference between the local cell terminal U1 and the neighboring cell terminal U2, for example, the local cell base station gNB1 calculates a difference between the reference signal received powers of the two synchronization signal blocks, if the difference is smaller than or equal to the interference threshold, for example, the interference threshold is 3dBm, it may be considered that the position distance between the cell terminal U1 and the neighboring cell terminal U2 is short, and a risk of high interference may exist; if the difference is greater than the interference threshold, for example, the interference threshold is 3dBm, it can be considered that the position distance between the cell terminal U1 and the neighboring cell terminal U2 is long, and there is no risk of high interference. Therefore, according to the inter-terminal interference determination method of the embodiment, whether interference exists between terminals can be determined more accurately, so that more accurate execution of interference avoidance can be facilitated.

In addition, another embodiment of the present application further provides a method for determining inter-terminal interference applied to a system, where the method for determining inter-terminal interference includes, but is not limited to, the following steps:

In addition, in an embodiment, the method for determining interference between terminals applied to the system may further include step S350, where step S350 and step S340 in the foregoing embodiment may be parallel steps or may also be synchronous steps.

Specifically, the step S350 is:

step S343, when the interference measured value between the terminals is not larger than the interference threshold value, the base station of the local cell determines that the terminal of the local cell and the terminal of the adjacent cell have interference.
