Description

Method and equipment for configuring CLI measurement resources

Technical Field

The present application relates to the field of wireless communications technologies, and in particular, to a method and a device for configuring a CLI measurement resource.

Background

There are two duplexing modes in the conventional mobile communication system, i.e., FDD (frequency division duplex) and TDD (time division duplex). FDD systems receive and transmit signals using different frequency bands at the same time, and TDD systems receive and transmit signals using different times at the same frequency band. Compared with TDD, FDD has the advantages of wide uplink coverage, simple interference processing, and the like, and does not require strict synchronization of the network. FDD must use paired transceiving frequency bands, which can fully utilize uplink and downlink frequency spectrum when supporting uplink and downlink symmetric services, and the frequency spectrum utilization ratio of FDD system will be reduced when supporting uplink and downlink asymmetric services.

The 5G (5Generation, fifth Generation) network is centered on user terminal experience, and realizes personalized and diversified service applications. The difference of uplink and downlink flow requirements of different services is large, and the traditional TDD and FDD systems are difficult to better match the diversified service requirements of the 5G network. In order to meet flexible change of uplink and downlink services, a flexible duplex technology or a dynamic TDD technology is provided.

The dynamic TDD technology breaks through the fixed configuration mode of uplink and downlink resources in the traditional cellular network system, and adaptively adjusts the uplink and downlink resources according to the service requirements, thereby improving the frequency spectrum utilization rate. Although the dynamic TDD technology may dynamically configure uplink and downlink Transmission directions according to the cell service state, when adjacent cells transmit information in different directions (uplink or downlink) on the same time-frequency resource, as shown in fig. 1, where a cell 1 is in Uplink (UL) and a cell 2 is in Downlink (DL), two types of CLI (Cross-Link Interference) may be caused, that is, Interference between TRP (Transmission Reception Point) -TRP and UE (User Equipment) -UE.

However, the CLI measurement between UE-to-UE has the characteristics of flexible trigger mechanism, scarce interference measurement resource, limited interference measurement capability, and complex synchronization and alignment mechanism of interference measurement Reference Signals (RSs). Because the CLI measurement between the UE-to-UE has the above characteristics, at this time, the CLI measurement is performed by allocating an RS resource to each TRP, and the obtained CLI result has a large error, so that the CLI between the UE-to-UE in the system cannot be accurately reflected, and further the CLIM performed according to the determined CLI result will have problems.

In summary, the CLI measurement result from terminal to terminal is not accurate.

In a first aspect, an embodiment of the present application provides a method for configuring a CLI measurement resource, where the method includes:

a scheduling center allocates RS resources to a first TRP, wherein interference UE in the first TRP processes uplink service on resources where CLI occurs;

and the scheduling center re-configures the RS resource for the first TRP according to the interference degree, wherein the RS resource of the first TRP with the large interference degree is more than that of the first TRP with the small interference degree.

In the method, a scheduling center allocates an RS resource to a first TRP, wherein interference UE in the first TRP processes an uplink service on a resource where CLI occurs; the scheduling center determines the interference degree of the CLI of the disturbing UE in the first TRP according to the CLI measurement result measured and reported by the disturbed UE in the second TRP; the interfered UE in the second TRP processes downlink service on resources where CLI occurs, and the CLI measurement result is obtained by measuring the interfered UE in the second TRP on a time-frequency resource position corresponding to an RS resource configured to the first TRP; and the scheduling center re-configures the RS resource for the first TRP according to the interference degree, wherein the RS resource of the first TRP with the large interference degree is more than that of the first TRP with the small interference degree. The method comprises the steps that a first TRP and a second TRP carry out CLI measurement on RS resources which are distributed to the first TRP by a scheduling center, the interference degree of the CLI of interference-exerting UE in the first TRP is determined according to the CLI measurement result, further more RS resources are distributed to the first TRP with high interference intensity to carry out CLI fine measurement if dynamic distribution is carried out on the RS resources which are measured by the CLI according to the determined interference degree, and further the CLI measurement result between UE-to-UE is more accurate.

In a possible embodiment, before the scheduling center allocates RS resources to the first TRP, the method further includes:

the scheduling center determines resources for CLI measurement according to the expected uplink and downlink service configuration information fed back by the TRP; and

and the scheduling center determines a first TRP containing interference UE and a second TRP containing interference UE according to the uplink and downlink service configuration information.

According to the method, the calling center determines resources for performing CLI measurement according to the expected uplink and downlink service configuration information fed back by the TRP, and simultaneously determines a first TRP containing interfering UE and a second TRP containing interfered UE according to the uplink and downlink service configuration information, so that RS resources can be configured for the determined first TRP, and CLI measurement is performed through the configured RS resources.

In a possible embodiment, the determining, by the scheduling center, the interference degree of the CLI of the interfering UE in the first TRP according to the CLI measurement result reported by the interfered UE in the second TRP by measuring includes:

the scheduling center receives a CLI measurement result reported by the second TRP, wherein the CLI measurement result is an original CLI measurement result measured by interfered UE in the second TRP or a CLI measurement result obtained by performing data integration according to the original CLI measurement result measured by the interfered UE in the second TRP;

and the scheduling center determines the interference degree according to the CLI measurement result and the interference weight coefficient of the second TRP.

In the method, when determining the interference degree of the CLI of the disturbing UE in the first TRP according to the CLI measurement result measured and reported by the disturbed UE in the second TRP, the scheduling center firstly receives the CLI measurement result reported by the second TRP, and then determines the interference degree of the CLI of the disturbing UE in the first TRP according to the CLI measurement result and the interference weight coefficient of the second TRP. The CLI measurement result received by the scheduling center is an original CLI measurement result measured by the interfered UE in the second TRP or a CLI measurement result obtained by performing data integration according to the original CLI measurement result measured by the interfered UE in the second TRP. Therefore, the scheduling center can determine the interference degree of the CLI of the interference-exerting UE in each first TRP according to the CLI measurement result uploaded by the second TRP, so that the scheduling center knows the interference strength of the CLI of the interference-exerting UE in each first TRP in the range corresponding to the scheduling center according to the interference degree, more RS resources are distributed for the first TRP with large interference degree, more detailed CLI measurement is carried out in the first TRP with small interference degree, and the CLI measurement result between the UE and the UE is more accurate.

In one possible embodiment, the determining, by the scheduling center, the interference degree according to the CLI measurement result and the interference weight coefficient of the second TRP includes:

the scheduling center determines an interference weight coefficient of a second TRP according to the number of interfered UEs in the second TRP and/or the set system priority of the second TRP;

and the scheduling center determines the interference degree according to the CLI measurement result and the determined interference weight coefficient of the second TRP.

In the method, the scheduling center determines an interference weight coefficient of the second TRP according to the number of interfered UEs in the second TRP and/or the set system priority of the second TRP; and then determining the interference strength of the CLI of the interfering UE in the first TRP according to the CLI measurement result and the determined interference weight coefficient of the second TRP, and further determining whether to perform RS resource reallocation according to the determined interference strength of the CLI of the interfering UE in the first TRP.

In a possible implementation manner, the reconfiguring, by the scheduling center, RS resources for the first TRP according to the interference degree includes:

the scheduling center determines an interference difference coefficient according to the interference degree;

and when the difference coefficient is larger than the set interference degree difference threshold value, the scheduling center reconfigures RS resources for the first TRP.

In the method, the scheduling center determines an interference difference coefficient according to the interference intensity of the CLI of the interfering UE in the first TRP, and when the interference difference coefficient is determined to be greater than a set interference intensity difference threshold, RS resources are configured for the first TRP again. Therefore, when the scheduling center determines that the interference source with great interference intensity difference exists, the RS resource is redistributed, CLI measurement with higher accuracy is carried out, and the CLIM efficiency is improved; and when the interference source with the great interference intensity difference does not exist, the RS resource is not reconfigured, and the system load is reduced.

In a possible embodiment, when the interference difference coefficient is greater than a set interference degree difference threshold, the scheduling center reconfigures RS resources for the first TRP, including:

the scheduling center allocates RS resources, the number of which is equal to the number of interference-causing UEs in a first TRP, for the first TRP, the interference degree of which is greater than a set first interference threshold;

the scheduling center allocates at least one RS resource for a first TRP with the interference degree larger than a set second interference threshold and not larger than a set first interference threshold, wherein one RS resource corresponds to at least two interference-exerting UEs;

the scheduling center allocates an RS resource for the first TRP with the interference degree larger than a set third interference threshold and not larger than a set second interference threshold;

wherein the first interference threshold > the second interference threshold > the third interference threshold.

In the method, a scheduling center sets three interference thresholds aiming at the interference degree of the CLI of the interference-causing UE in a first TRP, the first TRP can be divided into four grades according to the set interference thresholds, and RS resources with the number equal to that of the interference-causing UE in the first TRP are allocated to the first TRP when the determined interference degree of the CLI of the interference-causing UE in the first TRP is greater than the set first interference threshold; when the interference degree of the CLI of the interference-exerting UE in the first TRP is larger than a set second interference threshold and not larger than a set first interference threshold, allocating at least one RS resource for the first TRP, wherein one RS resource corresponds to at least two interference-exerting UEs; when the interference degree of the first TRP is larger than a set third interference threshold and not larger than a set second interference threshold, allocating an RS resource for the first TRP; and no RS resource can be allocated to the first TRP with the interference degree not greater than the set third interference threshold. Therefore, according to the determined interference intensity of the CLI of the interference UE in the first TRP, more RS resources can be allocated to the first TRP with high interference intensity to perform more precise CLI measurement, so that a more accurate CLI value is obtained, and the CLIM can be more accurate.

In a possible implementation manner, after the scheduling center reconfigures RS resources for the first TRP according to the interference degree, the method further includes:

the scheduling center determines the interference degree of the CLI of the interfered UE in the first TRP according to the CLI measurement result measured and reported by the interfered UE in the second TRP, wherein the CLI measurement result is obtained by measuring the interfered UE at the position corresponding to the RS resource reconfigured to the first TRP;

and the scheduling center instructs the first TRP to carry out CLIM according to the interference degree.

In the method, after the scheduling center reconfigures the RS resource for the first TRP according to the interference degree, the interference degree of the CLI of the interfering UE in the first TRP is determined according to the CLI measurement result measured and reported by the interfered UE in the second TRP, wherein the CLI measurement result is obtained by measuring the interfered UE at the position corresponding to the RS resource reconfigured to the first TRP; the first TRP is then instructed to CLIM according to the interference level. Therefore, the determined interference degree corresponding to the RS resource allocated to the first TRP is measured after the RS resource is reallocated, the obtained CLI measurement result is more accurate, and the CLIM can be more accurate.

In a possible embodiment, the method for indicating the first TRP to perform CLIM according to the interference degree includes:

the scheduling center indicates a first interference UE to suspend uplink data transmission through a first TRP, wherein the first interference UE is the UE of which the interference degree corresponding to the RS resource used in the first TRP is greater than a fourth interference threshold;

wherein the fourth interference threshold > the fifth interference threshold > the sixth interference threshold.

In the method, a scheduling center indicates a first interference-causing UE to suspend uplink data transmission through a first TRP, where the first interference-causing UE is a UE whose interference degree corresponding to an RS resource used in the first TRP is greater than a fourth interference threshold; a second interference UE is indicated to reduce uplink transmission power through a first TRP, wherein the second interference UE is the UE of which the interference degree corresponding to the RS resource used in the first TRP is greater than a fifth interference threshold and not greater than a fourth interference threshold; and indicating a third interference UE to perform uplink data transmission through the first TRP, wherein the third interference UE is the UE of which the interference degree corresponding to the RS resource used in the first TRP is greater than a sixth interference threshold and not greater than a fifth interference threshold; and indicating fourth interference UE to increase uplink transmission power through the first TRP, wherein the fourth interference UE is the UE of which the interference degree corresponding to the RS resource used in the first TRP is not more than a sixth interference threshold; therefore, the CLI measurement result is obtained by measuring on the reallocated RS resource, and more RS resources are allocated to the first TRP with high interference intensity during RS resource reconfiguration, so that the CLI measurement result between the UE and the UE is more accurate during CLI fine measurement, and the CLIM is more accurate.

In a second aspect, an embodiment of the present application provides a method for configuring a CLI measurement resource, where the method includes:

the method comprises the steps that a first TRP indicates interference-applying UE to send RS signals to interfered UE in a second TRP on RS resources distributed by a scheduling center, wherein the interference-applying UE in the first TRP processes uplink service on resources where CLI occurs, and the interfered UE in the second TRP processes downlink service on the resources where CLI occurs;

Therefore, the dispatching center can dynamically distribute the RS resource measured by the CLI according to the measured CLI result, the first TRP sends the RS signal according to the RS resource distributed by the dispatching center, and then a more accurate CLI measuring result is obtained, and the CLIM can be more accurate.

Detailed Description

For convenience of description, a scheduling center will be used below to refer to a newly added functional module for allocating CLI measurement resources;

the first TRP is used for referring to a TRP containing interference UE, wherein the interference UE is a UE which is transmitting uplink data, and the interference UE can generate cross link interference on a resource which is transmitting the uplink data to the UE which is performing downlink traffic in an adjacent TRP.

Using the second TRP to refer to the TRP including a victim UE that is a UE transmitting downlink data and that may be subject to cross-link interference on the resource transmitting the downlink data by UEs transmitting uplink data within neighboring TRPs.

In a communication system adopting dynamic TDD technology to transmit traffic between TRP and UE, CLI may occur between adjacent TRP and TRP in the system, and CLI may also occur between adjacent UE and UE.

As shown in fig. 1, TRP1 and TRP2 are adjacent base stations, and UE1 is adjacent to UE2, wherein UE1 in cell 1 corresponding to TRP1 performs uplink traffic transmission on one OFDM symbol resource (OFDM symbol 4) of slot resources (slot n), and UE2 in cell 2 corresponding to TRP2 performs downlink traffic transmission on the same OFDM symbol resource;

in this way, when the UE1 performs uplink traffic transmission, it will send an uplink transmission data signal to its own TRP1 on slot n OFDM symbol 4; meanwhile, the UE2 receives downlink data transmitted by its own TRP2 on the OFDM symbol 4 of slot n;

thus, due to the proximity of the UE1 and the UE2, the transmission data signal sent by the UE1 to the TRP1 to which the UE belongs may be received by the UE2 performing downlink traffic, and the UE1 in the TRP1 may generate cross-link interference to the UE2 in the TRP 2.

Therefore, in order to avoid the situation that data cannot be normally received due to overlarge UE-to-UE CLI when the UE performs downlink service transmission with the TRP to which the UE belongs, the UE-to-UE CLI possibly received by the UE needs to be monitored, and CLIM is performed according to the monitored CLI quantized value of the UE-to-UE CLI, so that the UE performing downlink service data transmission can smoothly receive corresponding downlink service data. However, no ideal UE-to-UE CLI measurement scheme exists in the prior art.

In order to solve the above problem, an embodiment of the present application provides a scheme for configuring CLI measurement resources, and in a specific implementation, a function module is newly added to a network structure formed by an existing TRP and UE, and is used for allocating CLI measurement resources; furthermore, the measurement result obtained by CLI measurement of the UE processing the downlink service can be integrated and analyzed.

It should be noted that the functional module may be arranged on an individual network-side device, for example, an individual network-side device scheduling center; may also be provided on the TRP.

In order to make the CLI measurement result accurate enough, the CLI measurement process according to the embodiment of the present invention is divided into two processes: a coarse measurement process and a fine measurement process.

In the process, the scheduling center distributes the available RS resources with equal number to each first TRP averagely, then the interference UE in the first TRP sends RS signals according to the RS resources configured by the scheduling center, meanwhile the interfered UE in the second TRP measures UE-to-UE CLI on the same resources and quantizes the measured value of the CLI, and then the interference degree of the CLI of the interference UE in each first TRP is determined by performing integration analysis according to the measured value of the CLI in the scheduling;

then, in a fine measurement stage, which may also be referred to as flexible granularity CLI measurement, in the process, the scheduling center divides the interference degree of the interfering UE in each first TRP to the interfered UE in the range of the scheduling center according to the interference degree of the CLI of the interfering UE in each first TRP obtained in the rough measurement stage and a preset interference degree threshold, and then allocates more RS resources to the first TRP with high interference degree; allocating few RS resources for the first TRP with low interference degree, even not allocating the RS resources; therefore, the first TRP with high interference degree can be allocated with more RS resources, so that CLI fine measurement can be carried out on different interference-exerting UEs, and a further scheduling center can carry out CLIM according to CLI measurement results of the CLI fine measurement so as to ensure that the interfered UEs can smoothly receive corresponding downlink service data.

The following will describe the scheme of the coarse measurement phase and the fine measurement phase in this application in detail with reference to the embodiments.

In specific implementation, the scheduling center may generate a global view according to the position of each TRP, and determine the adjacent TRPs of each TRP according to the global view.

Then, all TRPs in the control range of the scheduling center regularly report expected uplink and downlink service configuration information to the scheduling center, wherein the expected uplink and downlink service configuration information is the configuration information of the TRPs to time domain resources in an expected time period; subsequently, the scheduling center may determine, according to the expected uplink and downlink service configuration information, the uplink and downlink service states of each TRP on each time domain resource in the expected time period.

Generally, the TRP preferentially allocates transmission resources for uplink traffic, and allocates transmission resources for downlink traffic after allocating transmission resources for uplink traffic, so that there is only one chance that traffic transmission directions of two TRPs are opposite in one timeslot. And the data volume of data transmission is usually larger, and the possibility that the uplink and downlink traffic states of the TRP are unchanged exists on the time domain resources within a certain time length range.

Thus, the scheduling center can determine the uplink and downlink traffic state of each TRP on each time domain resource in the expected time period and the uplink and downlink traffic state of an adjacent TRP of the TRP on each time domain resource in the expected time period according to the global view and the expected uplink and downlink traffic configuration information.

Meanwhile, the UE-to-UE CLI is the cross link interference applied by the UE for transmitting the uplink data to the UE for transmitting the downlink data on the same time domain resource position, when the UE-to-UE CLI exists, the TRP corresponding to the UE for transmitting the uplink data is processing the uplink service, and the TRP corresponding to the UE for transmitting the downlink data is processing the downlink service, wherein the UE for transmitting the uplink data and the UE for transmitting the downlink data belong to two adjacent TRPs respectively.

As shown in fig. 2, the scheduling center may specify that UE-to-UE CLI may exist in UEs in adjacent TRPs with opposite uplink and downlink traffic transmission directions at the same time domain resource location, and process the TRP of the uplink data transmission traffic at the resource location with the opposite traffic transmission direction as a first TRP and process the TRP of the downlink data transmission traffic at the resource location with the opposite traffic transmission direction as a second TRP.

Meanwhile, on the time domain resource with opposite uplink and downlink service transmission directions determined according to the expected uplink and downlink service configuration information, when the scheduling center determines that the time length of the TRP with unchanged uplink and downlink service states reaches the set time length, CLI measurement is carried out in the time length range.

First, as shown in fig. 3, the CLI coarse measurement phase.

And after determining the first TRP and the second TRP, the scheduling center configures RS resources for the first TRP and performs rough measurement.

After the scheduling center allocates the RS resource to the first TRP, the scheduling center notifies the first TRP and the second TRP of the configuration of the RS resource.

When the scheduling center notifies the configuration condition of the RS resource to the first TRP and the second TRP, the scheduling center may be divided into multiple transmission modes according to different contents transmitted by the scheduling center, and is not limited to the following specific transmission modes.

In the first transmission mode, the scheduling center may establish a correspondence between the first TRP and the RS resource allocated to the first TRP, generate configuration information of the RS resource including the correspondence, and then transmit the configuration information of the RS resource to all of the first TRP and the second TRP.

As an example, the scheduling center configures one RS resource for each first TRP, generates configuration information of the RS resource including a correspondence between the first TRP and the RS resource, and then sends the configuration information of the RS resource to the first TRP and the second TRP, respectively.

In this way, after the first TRP receives the configuration information of the RS resource, the RS resource configured to the first TRP is determined according to the corresponding relation between the first TRP and the RS resource in the configuration information of the RS resource, and the interference UE in the jurisdiction range of the first TRP is instructed to send an RS signal to the interfered UE in the second TRP.

Correspondingly, after the second TRP receives the configuration information of the RS resources, all the RS resources allocated to the first TRP are determined according to the configuration information of the RS resources, and interfered UE in the jurisdiction range of the second TRP is instructed to receive RS signals sent by interfered UE in the first TRP at all the RS resource positions and perform CLI measurement.

It should be noted that after the scheduling center sends the configuration information of the RS resource to the first TRP and the second TRP, when the interfered UE in the second TRP receives the RS signal sent by the interfering UE in the first TRP on the corresponding RS resource, the first TRP to which the interfering UE sending the RS signal belongs may be determined according to the RS resource receiving the RS signal and the corresponding relationship between the first TRP and the RS resource.

And in a second transmission mode, the scheduling center independently transmits the RS resource allocated to the first TRP to the corresponding first TRP, and transmits the RS resource allocated to each first TRP and the corresponding first TRP to all the second TRPs.

As an example, the scheduling center configures an RS resource for each first TRP, establishes a corresponding relationship between the first TRP and the RS resource, and then the scheduling center separately transmits configuration information of the RS resource allocated to the first TRP to the corresponding first TRP; and then, transmitting each second TRP according to the configuration information of all RS resources allocated to the first TRP and the corresponding relation between the first TRP and the RS resources.

In this way, after the first TRP receives the configuration information of the RS resource sent by the scheduling center, the interfering UE in the jurisdiction range of the first TRP is indicated to send an RS signal to the interfered UE in the second TRP according to the configuration information of the RS resource.

Correspondingly, after the second TRP receives the configuration information of the RS resource, the interfered UE in the jurisdiction range of the second TRP is indicated to receive RS signals sent by the interfering UE in the first TRP at all RS resource positions according to the configuration information of all RS resources allocated to the first TRP, and CLI measurement is carried out.

It should be noted that after the scheduling center sends the configuration information of all RS resources allocated to the first TRP and the corresponding relationship between the first TRP and the RS resources to each second TRP, when the interfered UE in the second TRP receives an RS signal sent by the interfering UE in the first TRP on the RS resource allocated to the first TRP, the first TRP to which the interfering UE sending the RS signal belongs may be determined according to the received RS signal and the corresponding relationship between the first TRP and the RS resources.

The RS resource is composed of time domain resource, frequency domain resource and code domain resource. The time domain resources, the frequency domain resources and the code domain resources included in different RS resources are not completely the same.

And then, after the CLI measurement, the interfered UE in the second TRP quantizes the measurement result to obtain the CLI measurement value. In this way, after the interference UE in the second TRP is quantized in the CLI measurement, any interference UE in the second TRP may obtain a set of CLI measurement values, where one CLI measurement value corresponds to one RS resource, and the CLI measurement value indicates the degree of interference of the interference UE in the first TRP corresponding to the RS resource to the interference UE in the downlink traffic.

In specific implementation, when the interfered UE in the second TRP performs CLI measurement and quantizes the CLI measurement value to obtain the CLI measurement value, since the CLI applied by the interfering UE in the first TRP to the interfered UE in the second TRP is a physical quantity, in order to ensure that the quantized CLI measurement value can accurately represent the intensity of the CLI received by the interfered UE in the second TRP, the measured and quantized CLI measurement value is usually accurate to 5 or 6 digits after a decimal point.

Therefore, when the interfered UE in the second TRP reports the CLI measurement result to the second TRP to which the interfered UE belongs, the interfered UE in the second TRP can correspondingly report the CLI measurement result to the second TRP in different reporting modes under different conditions due to different system overhead limitation conditions.

Case one, the overhead is not limited.

In this case, since the overhead is not limited, the interfered UE in the second TRP can more flexibly select one reporting mode from different reporting modes to report the CLI measurement result to the second TRP. The specific reporting method is not limited to the following.

And in the first reporting mode, the interfered UE in the second TRP directly reports the CLI measurement result after the CLI measurement quantization to the second TRP to which the UE belongs.

For example, referring to fig. 3, a range managed and controlled by the scheduling center includes two second TRPs, which are TRP4 and TRP5, respectively, a disturbed UE a and a disturbed UE B are in a cell corresponding to TRP4, and a disturbed UE C and a disturbed UE D are in a cell corresponding to TRP 5;

the dispatching center also comprises 6 first TRPs in the range managed and controlled by the dispatching center, and the corresponding relation between the first TRPs and the RS resources is as follows: TRP 1-RS 1, TRP 2-RS 2, TRP 3-RS 3, TRP 6-RS 4, TRP 7-RS 5 and TRP 8-RS 6;

and the quantized CLI measurement value after CLI measurement is set to be taken 6 digits after the decimal point, after the TRP4 indicates the interfered UE a and UE B to perform CLI measurement, the interfered UE a and interfered UE B in the TRP4 quantize and report the CLI measurement value as shown in table 1:

TABLE 1

After the TRP5 indicates the interfered UE C and UE D to perform CLI measurement, the interfered UE C and interfered UE D in the TRP5 quantize and report CLI measurement values as shown in table 2:

TABLE 2

And when the interfered UE in the second reporting mode and the second TRP are roughly measured, data after the decimal point is not considered, and the data after the decimal point is processed in a rounding mode, so that the CLI measured value is simplified.

and the quantized CLI measurement value after CLI measurement is set to be 6 digits after decimal point, after TRP4 indicates disturbed UE a and UE B to perform CLI measurement, the CLI measurement values quantized by disturbed UE a and disturbed UE B in TRP4 are as shown in table 1, and after TRP5 indicates disturbed UE C and UE D to perform CLI measurement, the CLI measurement values quantized by disturbed UE C and disturbed UE D in TRP5 are as shown in table 2;

after the CLI measurement values measured by the interfered UE are simplified by the set rules, the CLI measurement values reported by the interfered UE a and the interfered UE B in the TRP4 are shown in table 3:

TABLE 3

The CLI measurements reported by victim UE C and victim UE D within TRP5 are shown in table 4:

TABLE 4

The second reporting mode can only be used in the course of rough measurement, and the reporting method reduces the complexity of data on the basis of sacrificing the accuracy of the data.

And in a third reporting mode, when the interfered UE in the second TRP roughly measures, mapping the CLI measured value obtained by measuring and quantizing the second TRP into a plurality of divided grades by setting a plurality of grades, and then representing the interference degree of the interference UE in each first TRP on the CLI applied by the interfered UE in the second TRP according to the grade.

For example: for example, referring to fig. 3, a range managed and controlled by the scheduling center includes two second TRPs, which are TRP4 and TRP5, respectively, a disturbed UE a and a disturbed UE B are in a cell corresponding to TRP4, and a disturbed UE C and a disturbed UE D are in a cell corresponding to TRP 5;

in the rough measurement, the CLI measurement value is divided into five grades according to a set threshold, which are respectively: very strong (CLI measure >10), strong (8< CLI measure ≦ 10), moderate (5< CLI measure ≦ 8), weak (2< CLI measure ≦ 5), very weak (CLI measure ≦ 2);

after the CLI measurement values measured by the interfered UE are simplified by the set rules, the CLI measurement values reported by the interfered UE a and the interfered UE B in the TRP4 are shown in table 5:

TABLE 5

The CLI measurements reported by victim UE C and victim UE D within TRP5 are shown in table 6:

TABLE 6

Further, in the embodiment of the present invention, five levels divided according to the set threshold may be digitized, for example: strong-5, strong-4, moderate-3, weak-2, weak-1;

after the CLI measurement values measured by the interfered UE are simplified by the set rules, the CLI measurement values reported by the interfered UE a and the interfered UE B in the TRP4 are shown in table 7:

TABLE 7

The CLI measurements reported by the victim UE C and the victim UE D in TRP5 are shown in table 8:

TABLE 8

In case two, the overhead is limited.

In this case, in order to save the system overhead, the interfered UE in the second TRP processes the measurement result by using a certain arithmetic rule, simplifies the CLI measurement value, and reports the simplified CLI measurement value to the second TRP to which the UE belongs.

In specific implementation, due to different set algorithms for simplifying the CLI measurement result, there may be multiple reporting modes for reporting the CLI measurement result to the second TRP, and the reporting modes are not limited to the following ones.

And when the interfered UE in the first reporting mode and the second TRP is roughly measured, data after the decimal point is not considered, and the data after the decimal point is processed in a rounding mode, so that the CLI measured value is simplified.

Therefore, the numerical digit of the CLI measured value reported by the interfered UE in the second TRP is reduced, the data complexity is reduced, and the system overhead can be further reduced.

For a specific example, refer to the example of the second method when the system overhead is not limited, and thus, details are not described again.

And in the second reporting mode, when the interfered UE in the second TRP roughly measures, mapping CLI measured values measured and quantized by the interfered UE in the second TRP into a plurality of divided grades by setting a plurality of grades, and then representing the interference degree of the CLI exerted by the interfered UE in each first TRP on the interfered UE in the second TRP through the grade levels.

Therefore, the interfered UE in the second TRP can map a large amount of data to a plurality of fixed levels, the numerical digit of the reported CLI measured value is reduced, the data complexity is reduced, and the system overhead can be further reduced.

For a specific example, refer to the example of the third method when the system overhead is not limited, and thus, details are not described again.

It should be noted that, the manner of simplifying the measurement result reported by the UE may be selected in many ways, and the above embodiment is only an example, and may be flexibly set according to the requirements in specific implementation.

And after the interfered UE in the second TRP reports the CLI measurement result, the second TRP receives the CLI measurement result reported by the interfered UE which is managed by the second TRP and reports the CLI measurement result to the scheduling center.

In a specific implementation, the reporting of the CLI measurement result from the second TRP to the scheduling center may be divided into two processing modes according to whether the second TRP processes the CLI measurement result reported by the interfered UE in the second TRP.

And the first processing mode and the second TRP can directly report the CLI measurement result to the scheduling center.

After the interfered UE in the second TRP reports the CLI measurement result, the second TRP can directly report the CLI measurement result reported by the interfered UE managed by the second TRP to the scheduling center.

And then after receiving the CLI measurement results reported by all the second TRPs, the scheduling center determines the interference degree of the CLI of the interference UE in each first TRP according to the received CLI measurement results.

In a specific implementation, the scheduling center needs to determine the interference degree of the CLI of the interfering UE in each first TRP according to the interference weight coefficient of the second TRP and the CLI measurement result reported by the second TRP.

Therefore, the scheduling center needs to determine the interference weight coefficient of the second TRP before determining the interference degree of the CLI of the interfering UE within each first TRP.

The factors for determining the interference weight coefficient of the second TRP by the scheduling center are different, and various ways of determining the interference weight coefficient may be determined, which are described below as examples.

And determining the interference weight coefficient of the second TRP by the scheduling center according to the number of interfered UEs contained in the second TRP in a first interference weight coefficient determining mode.

For example, referring to fig. 3, two second TRPs may be included in the TRPs managed by the scheduling center, which are TRP4 and TRP5, respectively, interfered UE a and interfered UE B are in the cell corresponding to TRP4, and interfered UE C and interfered UE D are in the cell corresponding to TRP 5;

if the number of interfered UEs in TRP4 can be quantized to interference weight coefficient weight _ TRP4, the number of interfered UEs in TRP5 can be quantized to interference weight coefficient weight _ TRP5, the values of weight _ TRP4 and weight _ TRP5 are between 0 and 1, and weight _ TRP4+ weight _ TRP5 is 1, then:

interference weight coefficient of TRP4

Interference weight coefficient of TRP5

And determining an interference weight coefficient of the second TRP by the scheduling center according to the preset system priority of the second TRP.

For example, referring to fig. 3, two second TRPs, respectively TRP4 and TRP5, may be included in the TRPs that the scheduling center may manage; the preset system priority level has three levels of 1, 2 and 3, and the larger the system priority level value is, the higher the system priority level is;

if the system priority of TRP4 is 3 and the system priority of TRP5 is 1, the system priority of TRP4 may be quantized to weight coefficient weight _ TRP4, the system priority of TRP5 may be quantized to weight coefficient weight _ TRP5, the values of weight _ TRP4 and weight _ TRP5 are between 0 and 1, and weight _ TRP4+ weight _ TRP5 is 1, then:

interference weight coefficient of TRP4

Interference weight coefficient of TRP5

It should be noted that the system priority of the second TRP may be set according to the requirement.

For example, if the area governed by TRP4 is a hot spot priority coverage area and the area governed by TRP5 is an ordinary residential building, the system priority of TRP4 may be set higher than the system priority of TRP 5;

if the area under the jurisdiction of the TRP4 is a residential area and the area under the jurisdiction of the TRP5 is an industrial park, the system priority of the TRP4 may be set higher than the system priority of the TRP 5.

And determining an interference weight coefficient of the second TRP by the scheduling center according to the number of interfered UEs contained in the second TRP and the preset system priority of the second TRP.

For example, referring to fig. 3, two second TRPs may be included in the TRPs managed by the scheduling center, which are TRP4 and TRP5, respectively, interfered UE a and interfered UE B are in the cell corresponding to TRP4, and interfered UE C and interfered UE D are in the cell corresponding to TRP 5; the preset system priority has three levels of 1, 2 and 3, and the higher the system priority value is, the higher the system priority is;

if the system priority of the TRP4 is 2 and the system priority of the TRP5 is 3, the number of UEs and the system priority of the TRP4 can be quantized to the weight coefficient weight _ TRP4, the number of UEs and the system priority of the TRP5 can be quantized to the weight coefficient weight _ TRP5, the values of weight _ TRP4 and weight _ TRP5 are between 0 and 1, and the weight _ TRP4+ weight _ TRP5 is 1, then:

interference weight coefficient of TRP4

Interference weight coefficient of TRP5

In addition, when the scheduling center is in the interference weight coefficient of the second TRP, the interference weight coefficient of the second TRP obtained by each calculation can be recorded, after enough historical data are obtained, statistical analysis is carried out according to the recorded historical data, the relation between the specific weight value setting and the final system performance is obtained, and then preferential selection is carried out according to the system performance.

It should be noted that, the above only illustrates some schemes that can be used to determine the weight coefficients, and in the implementation, the schemes can be flexibly set according to specific requirements, and the embodiments of the present invention do not limit this.

And after determining the interference weight coefficient of the second TRP, the scheduling center determines the interference degree of the CLI of the interference-causing UE in the first TRP according to the interference weight coefficient and the CLI measurement result reported by the second TRP.

In specific implementation, the scheduling center takes a weighted average of CLI measurement values measured by the interfered UEs in the second TRPs as the interference degree of the CLI of the interfering UE in the first TRP.

For example, referring to fig. 3, for the sake of convenience of calculation, the following CLI measurement values are directly illustrated by positive integers;

the TRP which can be controlled by the scheduling center comprises two second TRPs which are respectively TRP4 and TRP5, a disturbed UE A and a disturbed UE B are arranged in a cell corresponding to the TRP4, and an interference weight coefficient corresponding to the TRP4 is 0.5;

interfered UE C and interfered UE D exist in a cell corresponding to TRP5, and an interference weight coefficient corresponding to TRP5 is also 0.5;

if the CLI measurement result directly reported by the second TRP received by the scheduling center is shown in table 8:

TABLE 8

Thus, the interference level of the CLI of the offending UE within TRP 1:

interference degree of CLI of interfering UE within TRP 2:

interference degree of CLI of interfering UE within TRP 3:

interference degree of CLI of interfering UE within TRP 6:

interference degree of CLI of interfering UE within TRP 7:

interference degree of CLI of interfering UE within TRP 8:

that is, the CLI interference level of the interfering UE in each first TRP determined by the scheduling center is shown in table 9:

TABLE 9

And in the second processing mode, the second TRP carries out integration processing according to the CLI measurement result reported by the interfered UE in the second TRP, and then reports the CLI measurement result after integration processing to the scheduling center.

In specific implementation, the second TRP determines, for any one RS resource, an average value according to the CLI measurement value corresponding to the RS resource reported by each interfered UE, and the average value represents the interference degree of the interfered UE in the second TRP receiving the CLI applied by the interfering UE in the first TRP corresponding to the RS resource.

For example, referring to fig. 3, two second TRPs, which are TRP4 and TRP5, are included in the TRP4 corresponding to the cell, interfered UE a and interfered UE B are included in the TRP5 corresponding to the cell, and interfered UE C and interfered UE D are included in the TRP5 corresponding to the cell, if the CLI measurement values reported by the interfered UE a and the interfered UE B in TRP4 and the CLI measurement values reported by the interfered UE C and the interfered UE D in TRP5 are shown in table 8, the CLI measurement results obtained by integrating the CLI measurement values reported by the interfered UE governed by the second TRP according to the above calculation rules are shown in table 10:

watch 10

And then the second TRP reports the integrated CLI measurement result to a scheduling center, and the scheduling center determines the interference degree of the CLI of the interference UE in each first TRP according to the received CLI measurement result.

The method for determining the interference weight coefficient of the second TRP by the scheduling center is the same as the method for determining the interference weight coefficient of the second TRP by the scheduling center when the second TRP directly reports the CLI measurement result reported by the interfered UE governed by the scheduling center, and for the detailed description, reference may be made to the part of the CLI measurement result reported by the interfered UE governed by the scheduling center directly by the second TRP, so that the detailed description is omitted.

wherein, the interference weight coefficient corresponding to the TRP4 is 0.6, and the interference weight coefficient corresponding to the TRP5 is also 0.4, if the integrated CLI measurement result reported by the second TRP received by the scheduling center is shown in table 9, then:

interference degree of CLI of interfering UE within TRP 1: (5 × 0.6+4 × 0.4) × 0.5 — 2.3;

interference degree of CLI of interfering UE within TRP 2: (9 × 0.6+7 × 0.4) × 0.5 — 4.1;

interference degree of CLI of interfering UE within TRP 3: (11 × 0.6+13 × 0.4) × 0.5 ═ 5.9;

interference degree of CLI of interfering UE within TRP 6: 1.65 ═ 3.5 × 0.6+3 × 0.4 ═ 0.5;

interference degree of CLI of interfering UE within TRP 7: 1.4 ═ 2 × 0.6+4 × 0.4 ═ 0.5;

interference degree of CLI of interfering UE within TRP 8: (1 × 0.6+2 × 0.4) × 0.5 — 0.7.

That is, the CLI interference level of the interfering UE in each first TRP to the interfered UE in the second TRP in the management range of the scheduling center is as shown in table 11 below:

TABLE 11

It should be noted that, there may be a plurality of functions representing the interference degree of the interfering UE in the first TRP to the CLI applied by the interfered UE in the management and control range of the scheduling center, and the foregoing only exemplifies one possible implementation manner, and in a specific implementation process, a functional relation may be set autonomously according to requirements.

After determining the interference degree of interference UE in the first TRP on the CLI applied by the interfered UE in the control range of the scheduling center, the scheduling center determines whether to perform fine measurement according to the interference degree of the interference UE in the first TRP on the CLI applied by the interfered UE in the control range of the scheduling center and a preset CLI interference intensity difference threshold.

Second, as shown in fig. 4, CLI fine measurement phase.

In specific implementation, a scheduling center firstly determines an interference difference coefficient according to the interference degree of interference-applying UE in each first TRP to a CLI (common line interference) applied by interfered UE in a control range of the scheduling center;

then comparing the interference difference coefficient with a preset interference degree difference threshold value of the CLI, and determining that fine measurement is required when the interference difference coefficient is larger than the preset interference degree difference threshold value of the CLI;

otherwise, it is determined that fine measurements are not needed.

During specific implementation, the scheduling center firstly needs to determine an interference difference coefficient according to the determined interference degree of interference-causing UE in the first TRP to the CLI of interfered UE in the management and control range of the scheduling center.

There are various ways to determine the interference difference coefficient according to different set parameters representing the interference difference coefficient, which will be exemplified below.

The maximum difference coefficient is the difference value between the maximum value of the interference degree of the interference UE in the first TRP to the CLI applied by the interfered UE in the management and control range of the scheduling center and the minimum value of the interference degree.

For example, referring to fig. 4, the CLI interference level that the interfering UE in the first TRP finally determined by the scheduling center exerts on the interfered UE in the second TRP within the control range of the scheduling center is as shown in table 9 above.

When the maximum difference coefficient is determined, the maximum value of the CLI interference degree of the interference UE in the first TRP to the interfered UE in the second TRP in the control range of the scheduling center is determined to be 12 by the scheduling center;

the minimum value of the CLI interference degree of the interference-applying UE in the first TRP to the interfered UE in the second TRP in the management and control range of the scheduling center is 1.5;

and finally, the scheduling center determines the interference difference coefficient to be 12-1.5-11.5 according to a set rule.

And (II) the maximum difference coefficient is the variance of the interference degree of the interference UE in each first TRP to the CLI applied by the interfered UE in the dispatching center.

When determining the maximum difference coefficient, the scheduling center determines that the average value of the CLI interference degrees applied by the interfered UE in each first TRP to the interfered UE in the second TRP in the control range of the scheduling center is (4.5+8+12+3.25+3+1.5) ÷ 6 ═ 5.375;

the final dispatching center determines the interference difference coefficient { (4.5-5.375) according to a set rule²+(8-5.375)²+(12-5.375)²+(3.25-5.375)²+(3-5.375)²+(1.5-5.375)²}÷6＝12.7864583。

And (III) the maximum difference coefficient is the standard deviation of the interference degree of the interference UE in each first TRP to the CLI applied by the interfered UE in the dispatching center.

the variance of the CLI interference degree exerted by the interference UE in each first TRP to the interference UE in the second TRP in the control range of the scheduling center { (4.5-5.375)²+(8-5.375)²+(12-5.375)²+(3.25-5.375)²+(3-5.375)²+(1.5-5.375)²}÷6＝12.7864583；

The final dispatching center determines according to the set rule

And then, the scheduling center compares the determined interference difference coefficient with a preset interference degree difference threshold value to determine whether to reconfigure the RS resource.

For example, the scheduling center may use a difference value between a maximum value of interference degrees and a minimum value of interference degrees of CLIs that the interfering UE in the first TRP applies to the interfered UE in the management and control range of the scheduling center as an interference difference coefficient, the set interference degree difference threshold is 5, and the determined interference degrees of the interfering UE in the first TRP to the CLI of the interfered UE in the management and control range of the scheduling center are as shown in table 9:

then the scheduling center calculates the interference difference coefficient as: 12-1.5-10.5;

since 10.5>5, that is, the interference difference coefficient is greater than the preset interference degree difference threshold, the scheduling center determines that fine measurement is required.

And after determining that fine measurement needs to be carried out, the scheduling center allocates RS resources for the first TRP.

In a specific implementation process, in order to more accurately measure the CLI interference degree of interfering UE in the first TRP, the scheduling center allocates more RS resources to the first TRP with strong CLI interference degree caused by the interfering UE to the interfered UE, so that the interfering UE in the first TRP can perform higher-accuracy CLI measurement.

After the RS resources are determined to need to be reconfigured, the rule for the scheduling center to reconfigure the RS resources for the first TRP may be specifically set according to specific requirements, so that there are various ways to allocate the RS resources according to the difference of the preset rule for reconfiguring the RS resources for the first TRP, and the method is not limited to the following specific ways.

RS resource reconfiguration mode one

In specific implementation, the scheduling center compares the determined interference degree of the CLI of the interfering UE in each first TRP with a set interference threshold, and allocates RS resources with the same number as the interfering UE in the first TRP to the first TRP when the interference degree is greater than the set interference threshold;

and when the interference degree is not greater than the set interference threshold, allocating an RS resource for the first TRP.

For example, when the scheduling center uses the difference between the maximum value of the interference degree of the CLI applied by the interfering UE in the first TRP to the interfered UE in the management and control range of the scheduling center and the minimum value of the interference degree as the interference difference coefficient, the interference degree difference threshold is 5 and the interference threshold is 6, and the determined interference degree of the interfering UE in the first TRP to the CLI of the interfered UE in the management and control range of the scheduling center is as shown in table 9, the scheduling center calculates the interference difference coefficient to obtain: 12-1.5-10.5;

since 10.5 is greater than 5, namely the interference difference coefficient is greater than the preset interference degree difference threshold, the scheduling center determines that fine measurement needs to be carried out;

then, the scheduling center line compares the interference degree of the CLI of the interfering UE in each first TRP with a set interference threshold, and determines that the interference degree of the interfering UE in TRP2 and TRP3 to the CLI of the interfered UE in the second TRP is greater than the set interference degree threshold, so that the scheduling center allocates the same number of RS resources as the interfering UEs in TRP2 and TRP3 during fine measurement;

meanwhile, the scheduling center allocates one RS resource to TRP1 and TRPs 6 to TRP7, respectively, at the time of fine measurement.

RS resource reconfiguration mode two

In specific implementation, the scheduling center divides the first TRP into four levels according to three interference thresholds: strong (CLI measurement >10), medium (7< CLI measurement ≦ 10), weak (3< CLI measurement ≦ 7), very weak (CLI measurement ≦ 3);

when the determined interference degree of the CLI of the interference UE in the first TRP belongs to the grade of 'strong', the scheduling center allocates RS resources with the same number as the interference UE in the first TRP for the first TRP when performing fine measurement;

when the determined interference degree of the CLI of the interference-exerting UE in the first TRP belongs to the grade of 'middle', the scheduling center allocates at least one RS resource for the first TRP when performing fine measurement, and each RS resource corresponds to at least two interference-exerting UEs;

when the determined interference degree of the CLI of the interference UE in the first TRP belongs to the level of 'weak', the scheduling center allocates an RS resource for the first TRP1 when performing fine measurement.

When the determined interference degree of the CLI of the interference UE in the first TRP belongs to the grade of 'extremely weak', the scheduling center does not allocate RS resources to the first TRP when performing fine measurement, namely the first TRP does not participate in the CLI fine measurement.

For example, the difference value between the maximum value of the interference degree of the CLI applied by the interfering UE in the first TRP to the interfered UE in the control range of the scheduling center and the minimum value of the interference degree is used as an interference difference coefficient by the scheduling center, the interference difference threshold is 5, and the three interference thresholds are 10, 7 and 4 respectively;

and 4 interfering UEs (UE a, UE b, UE c, UE d) are included in the range of TRP2, and 3 interfering UEs (UE1, UE2, UE3) are included in the range of TRP 3;

and when the interference degree of the CLI of the interference UE in the first TRP belongs to the level of 'middle', every two UEs share one RS resource;

and the determined interference degree of the disturbing UE in the first TRP to the CLI of the disturbed UE in the control range of the scheduling center is as shown in table 9, the scheduling center calculates an interference difference coefficient to obtain: 12-1.5-10.5;

then, the scheduling center line compares the interference degree of the CLI of the interfering UE in each first TRP with a set interference threshold, and determines:

interference degree of interference (CLI) exerted by interference UE in TRP3 on interfered UE in a second TRP is more than 10, belonging to the grade of 'strong', and a scheduling center allocates RS resources for TRP3 with the same number as interference UE in the scheduling center in fine measurement, namely RS1 is allocated to UE1 in TRP3, RS2 is allocated to UE2 in TRP3, and RS3 is allocated to UE3 in TRP 3;

interference degree of interference UE in TRP2 to CLI applied by interfered UE in second TRP is more than 7 and less than 10, belonging to the grade of 'middle', and the scheduling center allocates 2 RS resources for TRP2 when in fine measurement; for example, RS4 and RS5 are allocated to TRP2, UE a and UE b within TRP2 share RS resource 4, and UE c and UE d within TRP2 share RS resource 4;

interference degree of interference UE in TRP1 to CLI of interference UE in second TRP is larger than 4 and smaller than 7, belonging to the grade of weak, when the scheduling center is used for fine measurement, 1 RS resource is allocated for TRP1, such as RS6 is allocated to TRP1, and interference UE in TRP1 shares RS 6;

interference degree of interference of interfering UE in TRP6, TRP7 and TRP8 to CLI of interfered UE in the second TRP is less than 4, and RS resources are not allocated to TRP6, TRP7 and TRP8 by the scheduling center.

And after the scheduling center determines the RS resource during the fine measurement, the configuration information of the RS resource is respectively sent to the first TRP and the second TRP again.

In a specific fact, the processing mode when the scheduling center sends the configuration information of the RS resource to the first TRP and the second TRP respectively, and the CLI measurement value obtained by performing CLI measurement and quantization by the interfered UE in the second TRP are consistent with those obtained when the CLI measurement value is roughly measured. Therefore, they are not described in detail.

Finally, the measurement results of the CLI measurement reported by the interfered UE in the second TRP are shown in the following table.

For example, referring to fig. 4, an RS resource reconfiguration mode two is adopted to perform RS resource reconfiguration on the first TRP, and for convenience of calculation and description, the following CLI measurement value is directly exemplified by a positive integer;

after the scheduling center is the RS resource reconfigured by the first TRP, the corresponding relationship between the first TRP and the RS resource is as follows: RS1-TRP3-UE1, RS2-TRP3-UE2, RS3-TRP3-UE3, RS4-TRP2-UE a and UE b, RS5-TRP2-UE c and UE d, RS6-TRP 1;

the CLI measurements quantified and reported by the victim UE C and the victim UE D in TRP4 are shown in table 12 below:

TABLE 12

The CLI measurement values quantified and reported by the disturbed UE C and the disturbed UE D in TRP5 are shown in table 13 below:

watch 13

Subsequently, the interfered UE in the second TRP gives the measurement result of the CLI measurement to the second TRP which the interfered UE belongs to.

It should be noted that when the measurement result is reported, the measurement is performed finely by this process, so the CLI measurement value cannot be simplified.

And after the interfered UE reports the CLI measurement result, the second TRP receives the CLI measurement result reported by the interfered UE which is managed by the second TRP and reports the CLI measurement result to the scheduling center.

During fine measurement, the second TRP receives and reports the CLI measurement result reported by the interfered UE administered by the second TRP, and the scheduling center determines that the process of obtaining the interference degree corresponding to each RS resource by performing CLI measurement is the same as that of the rough measurement, so that details are not repeated.

And after the scheduling center completes the fine measurement and obtains the interference degree of the CLI of the disturbing UE in the first TRP, the scheduling center performs CLIM according to the interference degree of the CLI of the disturbing UE in the first TRP obtained after the fine measurement.

The rule for performing the CLIM by the scheduling center according to the interference degree of the CLI of the interfering UE in the first TRP obtained after the fine measurement can be specifically set according to specific requirements, so that there are various CLIM modes according to different preset CLIM rules.

Dispatching center carries out CLIM mode one

The scheduling center presets an adjustment threshold for performing CLIM, and when the interference degree obtained by fine measurement is greater than the adjustment threshold, the transmission power of interference-causing UE in the first TRP corresponding to the interference degree is indicated to be adjusted;

and when the interference degree obtained by the fine measurement is not greater than the adjustment threshold, indicating the first TRP corresponding to the interference degree and the interference UE in the first TRP corresponding to the interference degree to carry out data transmission.

For example, referring to fig. 4, setting the adjustment threshold to 5, when RS1 is allocated to UE1 in TRP3, RS2 is allocated to UE2 in TRP3, RS3 is allocated to UE3 in TRP3, RS4 is allocated to UE a and UEb in TRP2, RS5 is allocated to UEc and UEd in TRP2, and RS6 is allocated to TRP1, and the scheduling center reports the following list 14 according to the CLI measurement results reported by the interfered UEs in the second TRP:

TABLE 14

According to the set adjustment threshold, the interference intensity of the UE L in the TRP3 corresponding to the RS3 is larger than the set fourth interference threshold, so that the scheduling center instructs the TRP3 to reduce the transmission power of the UE3 so as to reduce the CLI applied by the interfering UE3 in the TRP3 to the interfered UE in the range of the scheduling center;

and the CLIs corresponding to the RS1, the RS2, and the RS4 to RS6 are all smaller than the fourth interference threshold, the transmission power of the UE corresponding to the first TRP corresponding thereto may not be adjusted.

Scheduling center performing CLIM mode two

The scheduling center may further subdivide the adjustment threshold, for example, set three adjustment thresholds, which are: 8. 5, 2;

when the interference degree determined by the fine measurement is greater than 8, the CLI caused by the interference-applying UE corresponding to the interference degree to the interfered UE in the management and control range of the scheduling center can be determined to be extremely large, downlink service of the interfered UE is seriously affected, scheduling transmission can be avoided, and the downlink service of the interfered UE is suspended.

When the interference degree determined by the fine measurement is greater than 5 and less than 8, determining that the CLI (common interference indicator) of the interfered UE corresponding to the interference degree to the interfered UE in the control range of the scheduling center is large, and the scheduling center indicates to turn down the transmitting power of the interfered UE in the first TRP corresponding to the interference degree;

when the interference degree determined by the fine measurement is greater than 2 and less than 5, determining that the CLI of the interfered UE corresponding to the interference degree to the interfered UE in the management and control range of the scheduling center is small, and indicating the first TRP corresponding to the interference degree and the interfered UE in the first TRP corresponding to the interference degree to perform data transmission;

when the interference degree determined by the fine measurement is less than 2, the CLI caused by the interference-applying UE corresponding to the interference degree to the interfered UE in the management and control range of the scheduling center can be determined to be extremely small, and the emission power of the interference-applying UE in the first TRP corresponding to the interference degree can be indicated to be properly adjusted, so that the interference-applying UE can better perform uplink service transmission.

For example, referring to fig. 4, three adjustment thresholds are set, which are: 8. 5, 2;

when RS1 is allocated to UE1 in TRP3, RS2 is allocated to UE2 in TRP3, RS3 is allocated to UE3 in TRP3, RS4 is allocated to UEa and UEb in TRP2, RS5 is allocated to UEc and UEd in TRP2, and RS6 is allocated to TRP1, and the results of CLI measurements reported by the scheduling center according to the interfered UEs in the second TRP are shown in table 15 below:

watch 15

According to the set adjustment threshold, the interference intensity of the UE L in the TRP3 corresponding to the RS3 is larger than 5 and smaller than 8, the scheduling center instructs the TRP3 to reduce the transmission power of the UE3 so as to reduce the CLI exerted by the disturbing UE3 in the TRP3 on the disturbed UE in the range of the scheduling center;

when the CLIs corresponding to the RS1 and the RS2 are both greater than 2 and less than 5, the TRP3 directly performs uplink data transmission with the UE1 and the UE2 without adjusting the transmission power of the UE1 in the TRP3 and the transmission power of the UE2 in the TRP 3;

when the CLIs corresponding to the RS4 are both more than 2 and less than 5, the TRP2, UEc and UEd directly carry out uplink data transmission, and the transmitting power of UEc and UEd in the TRP2 is not adjusted;

when the CLIs corresponding to the RS6 are both greater than 2 and less than 5, performing uplink data transmission on all interfering UEs in the TRP1 and the TRP1, and not adjusting the transmission power of all interfering UEs in the TRP 1;

when the CLIs corresponding to the RS4 are both less than 2, the scheduling center may instruct the TRP2 to appropriately increase the transmission power of the ue a and the ue b to improve the quality of uplink transmission service of the ue a and the ue b.

As shown in fig. 5, in the embodiment of the present invention, a time for completing one coarse measurement may be referred to as a CLI short measurement period, and a time for completing one coarse measurement and one fine measurement may be referred to as a CLI long measurement period, so that one CLI long measurement period includes at least two CLI short measurement periods.

After RS resources in one CLI long measurement period are removed from RS resources in one CLI short measurement period for performing coarse measurement, the remaining RS resources should be greater than or equal to RS resources required for performing fine measurement.

step 606, the scheduling center determines an interference difference coefficient according to the interference degree of interference-causing UE in the first TRP to CLI applied by interfered UE in the control range of the scheduling center;

step 607, the dispatching center judges whether the interference difference coefficient is larger than the set interference degree difference threshold value, if yes, step 608 is executed; otherwise, executing step 601;
