Description

Method and equipment for configuring CLI measurement resources

This application claims the priority of a Chinese patent application filed with the Chinese Patent Office on June 14, 2019, the application number is 201910515986.9, and the invention title is "a method and device for configuring CLI measurement resources", the entire content of which is incorporated by reference In this application.

Technical field

This application relates to the field of wireless communication technologies, and in particular to a method and device for configuring CLI measurement resources.

Background technique

There are two duplex modes in traditional mobile communication systems, namely FDD (Frequency Division Duplex) and TDD (Time Division Duplex). The FDD system uses different frequency bands to receive and transmit signals at the same time, while the TDD system uses different times to receive and transmit signals on the same frequency band. Compared with TDD, FDD has the advantages of wide uplink coverage and simple interference handling, and does not require strict network synchronization. FDD must use paired transceiver bands to make full use of the uplink and downlink spectrum when supporting symmetric uplink and downlink services. When supporting asymmetric uplink and downlink services, the spectrum utilization rate of the FDD system will be reduced.

5G (5Generation, Fifth Generation) network is centered on user terminal experience and realizes personalized and diversified business applications. The upstream and downstream traffic requirements of different services vary greatly, and traditional TDD and FDD systems cannot better match the diverse service requirements of 5G networks. In order to meet the flexible changes of upstream and downstream services, flexible duplex technology, or dynamic TDD technology, is proposed.

Dynamic TDD technology breaks through the fixed configuration of uplink and downlink resources in traditional cellular network systems, and adaptively adjusts uplink and downlink resources according to business needs, thereby improving spectrum utilization. Although the dynamic TDD technology can dynamically configure the uplink and downlink transmission directions according to the cell service status, when neighboring cells transmit information in different directions (uplink or downlink) on the same time-frequency resource, as shown in Figure 1, where cell 1 is in Uplink (UL), cell 2 is in downlink (DL), at this time, two types of CLI (Cross-Link Interference) will be brought, namely TRP (Transmission Reception Point)-TRP and UE (User Equipment, user terminal)-UE interference.

However, the CLI measurement between UE-to-UE has the characteristics of flexible triggering mechanism, scarce interference measurement resources, limited interference measurement capability, and complex synchronization and alignment mechanisms of interference measurement reference signals (RS). Because the CLI measurement between UE-to-UE has the above characteristics, at this time, the CLI measurement is performed by allocating an RS resource for each TRP. The CLI results obtained will have a large error, which cannot accurately reflect the system. The situation of the CLI between UE-to-UE and CLIM based on the determined CLI result will also have problems.

In summary, the current terminal-to-terminal CLI measurement result is inaccurate.

Summary of the invention

The present invention provides a method and equipment for configuring CLI measurement resources to solve the problem of inaccurate CLI measurement results from terminal to terminal in the prior art.

An embodiment of the application provides a method for configuring CLI measurement resources, the method including:

The scheduling center configures the RS resources to the first TRP, where the interfering UE in the first TRP processes the uplink service on the resources where the CLI occurs;

The scheduling center determines the degree of interference of the CLI of the disturbing UE in the first TRP according to the CLI measurement results reported by the victim UE in the second TRP; wherein, the disturbed UE in the second TRP is experiencing CLI Resource uplink processing downlink services, the CLI measurement result is measured by the victim UE in the second TRP at the time-frequency resource location corresponding to the RS resource configured for the first TRP;

The scheduling center re-configures RS resources for the first TRP according to the interference level, where the RS resources of the first TRP with a large interference level are more than the RS resources of the first TRP with a small interference level.

In the above method, the scheduling center configures RS resources to the first TRP, wherein the interfering UE in the first TRP processes uplink services on the resources where the CLI occurs; the scheduling center measures and reports the disturbed UE in the second TRP The CLI measurement result of the first TRP determines the interference level of the CLI of the disturbing UE in the first TRP; wherein the victim UE in the second TRP processes the downlink service on the resources where the CLI occurs, and the CLI measurement result is the second TRP The interfered UE in the first TRP is measured at the position of the time-frequency resource corresponding to the RS resource allocated to the first TRP; the scheduling center re-configures the RS resource for the first TRP according to the interference level, and the first TRP with the greater interference level The RS resources of the TRP are more than the RS resources of the first TRP with less interference. The first TRP and the second TRP perform CLI measurement on the RS resources allocated to the first TRP by the scheduling center, and determine the interference level of the CLI that disturbs the UE in the first TRP according to the CLI measurement results, and further if the interference is determined according to the determined interference To a certain extent, the RS resources measured by the CLI are dynamically allocated, and more RS resources are allocated for the first TRP with high interference intensity to perform CLI fine measurement, thereby making the measurement results of the CLI between UE-to-UE more accurate.

Detailed ways

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

The first TRP is used to refer to the TRP that includes the interfering UE. The interfering UE is a UE that is transmitting uplink data, and the interfering UE may perform downlink services on neighboring TRPs on the resources for transmitting uplink data. Of the UE produces cross-link interference.

The second TRP is used to refer to the TRP that includes the victim UE. The victim UE is the UE that is transmitting downlink data, and the victim UE may be affected by the uplink data being transmitted in the neighboring TRP on the resources for the downlink data transmission. The UE imposes cross-link interference.

In a communication system that uses dynamic TDD technology for service transmission between TRP and UE, CLI may appear between TRP and TRP that are adjacent in the system, and CLI may also appear between adjacent UEs and UEs.

As shown in Figure 1, TRP1 and TRP2 are adjacent base stations, and UE1 and UE2 are adjacent. Among them, UE1 in cell 1 corresponding to TRP1 is in a certain OFDM symbol resource (slot n). ) Performs uplink service transmission, while UE2 in cell 2 corresponding to TRP2 performs downlink service transmission on the same OFDM symbol resource;

In this way, when UE1 performs uplink service transmission, it will send an uplink transmission data signal to its own TRP1 on OFDM symbol 4 of slot n; at the same time, UE2 receives its own TRP2 transmission on OFDM symbol 4 of slot n Downlink data;

In this way, due to the proximity of UE1 and UE2, the transmission data signal sent by UE1 to TRP1 to which it belongs may be received by UE2 performing downlink services, and UE1 in TRP1 may cause cross-link interference to UE2 in TRP2.

Based on this, in order to avoid the situation that the UE-to-UE CLI received by the UE is too large and the data cannot be received normally when the UE performs downlink service transmission with its own TRP, it is necessary to check the UE-to-UE The CLI monitors and performs CLIM according to the monitored CLI quantified value of the UE-to-UE CLI to ensure that the UE performing the downlink service data transmission can smoothly receive the corresponding downlink service data. However, there is still no ideal UE-to-UE CLI measurement solution in the prior art.

In order to solve the above-mentioned problems, an embodiment of this application proposes a solution for configuring CLI measurement resources. In specific implementation, a new functional module is added to the existing network structure composed of TRP and UE for allocating CLI measurement resources; further It can also perform integrated analysis on the measurement results obtained by the CLI measurement of the UE processing the downlink service.

It should be noted that the above-mentioned functional modules can be set on a separate network side device, for example, a separate network side device dispatch center; it can also be set on a TRP.

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

Among them, the coarse measurement phase can also be called the uniform coarse-grained CLI measurement phase. In this process, the scheduling center will evenly allocate an equal number of available RS resources for each first TRP, and then disturb the UE in the first TRP. The RS signal is sent according to the RS resource configured by the scheduling center, and the victim UE in the second TRP measures the UE-to-UE CLI on the same resource and quantifies the CLI measurement value, and then performs integrated analysis based on the CLI measurement value in the scheduling , Determine the degree of interference of the CLI that disturbs the UE in each first TRP;

Then, there is the fine measurement phase, which can also be called the flexible granularity CLI measurement. In this process, the dispatch center will base on the interference level of the CLI that disturbs the UE in each first TRP obtained in the coarse measurement phase and the preset interference level threshold. , Divide the interfering UE in each first TRP into the interference degree of the interfered UE within the scope of the scheduling center, and then allocate more RS resources to the first TRP with high interference degree; and for the first TRP with low interference degree TRP allocates less RS resources, or even no RS resources; in this way, the first TRP with high interference level can allocate more RS resources, and then can perform CLI fine measurement for different interfering UEs, and the further scheduling center can fine according to CLI CLIM is performed on the measured CLI measurement results to ensure that the interfered UE can smoothly receive the corresponding downlink service data.

The schemes of the coarse measurement phase and the fine measurement phase in this application will be described in detail below in conjunction with embodiments.

In specific implementation, the dispatch center may generate a global view according to the location of each TRP, and determine the neighboring TRPs of each TRP according to the global view.

Then, all TRPs within the control range of the dispatch center periodically report the expected uplink and downlink service configuration information to the dispatch center, where the expected uplink and downlink service configuration information is the TRP's configuration information for time domain resources in the expected time period ; Subsequently, the scheduling center can determine the uplink and downlink service status of each TRP on each time domain resource in the expected time period according to the expected uplink and downlink service configuration information.

In general, TRP prioritizes the configuration of transmission resources for uplink services, and only configures transmission resources for downlink services after the transmission resources are configured for uplink services. In this way, there is only one opportunity for the service transmission directions of two TRPs to be opposite in a time slot. In addition, the data volume of data transmission is usually relatively large, and there is a possibility that the status of the TRP upstream and downstream services remains unchanged on the time domain resources within a certain duration.

In this way, the scheduling center can determine the uplink and downlink service status of each TRP on each time domain resource in the expected time period according to the global view and the expected uplink and downlink service configuration information, and the expected neighboring TRPs of the TRP. The status of uplink and downlink services on each time domain resource in the time period.

At the same time, the UE-to-UE CLI is the cross-link interference that the UE that transmits uplink data imposes on the UE that transmits downlink data on the same time domain resource location. When UE-to-UE CLI exists, the uplink data transmission The TRP corresponding to the UE is processing uplink services, and the TRP corresponding to the UE transmitting downlink data is processing downlink services, wherein the UE transmitting uplink data and the UE transmitting downlink data belong to two adjacent TRPs respectively.

As shown in Figure 2, in this way, the scheduling center can specify that UE-to-UE CLI may exist in adjacent TRPs in the same time domain resource location where the uplink and downlink service transmission directions are opposite, and in the resource location with the opposite service transmission direction The TRP that processes the uplink data transmission service is used as the first TRP, and the TRP that processes the downlink data transmission service at the resource location opposite to the service transmission direction is used as the second TRP.

At the same time, on the time domain resources with the opposite transmission directions of the uplink and downlink services determined according to the expected uplink and downlink service configuration information, when the scheduling center determines that the duration of the TRP's uplink and downlink service status remains unchanged reaches the set duration, this period of time Perform CLI measurements within the range.

1. As shown in Figure 3, the CLI rough measurement stage.

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 RS resources to the first TRP, it will notify the first TRP and the second TRP of the configuration of the RS resources.

Among them, when the dispatch center notifies the first TRP and the second TRP of the configuration of the RS resources, according to the content sent by the dispatch center, it can be divided into multiple transmission methods, which are not limited to the following.

Transmission method 1: The scheduling center can establish the correspondence relationship between the first TRP and the RS resource allocated to the first TRP, and generate configuration information of the RS resource including the correspondence relationship, and then send the RS resource configuration information to all The first TRP and the second TRP.

As an example, the scheduling center configures an RS resource for each first TRP, and generates configuration information of the RS resource containing the corresponding relationship between the first TRP and the RS resource, and then sends the configuration information of the RS resource to the first TRP. TRP and second TRP.

In this way, after the first TRP receives the configuration information of the RS resource, it determines the RS resource configured for itself according to the corresponding relationship between the first TRP and the RS resource in the configuration information of the RS resource, and instructs the interfering UE within its jurisdiction to The victim UE in the second TRP sends an RS signal.

Correspondingly, after the second TRP receives the configuration information of the RS resources, it determines all the RS resources allocated to the first TRP according to the configuration information of the RS resources, and instructs the disturbed UEs within its own jurisdiction to receive at all RS resource locations. Interfering with the RS signal sent by the UE in the first TRP and performing CLI measurement.

It should be noted that after the scheduling center sends the configuration information of the RS resources to the first TRP and the second TRP respectively, the victim UE in the second TRP receives on the corresponding RS resources the information sent by the disturbing UE in the first TRP. In the case of an RS signal, the first TRP to which the interfering UE sending the RS signal belongs can be determined according to the RS resource of the received RS signal and the correspondence between the first TRP and the RS resource.

Transmission mode 2: The scheduling center separately sends the RS resources allocated to the first TRP to the corresponding first TRP, and sends the RS resources allocated to each first TRP and the corresponding first TRP to all second TRPs.

As an example, the scheduling center configures an RS resource for each first TRP, and establishes the corresponding relationship between the first TRP and the RS resource, and then the scheduling center separately sends the configuration information of the RS resource allocated to the first TRP to the corresponding first TRP. A TRP; then, the configuration information of all RS resources allocated to the first TRP and the correspondence between the first TRP and the RS resources are sent to each second TRP.

In this way, after the first TRP receives the RS resource configuration information sent by the scheduling center, it instructs the perturbing UE within its own jurisdiction to send the RS signal to the victim UE in the second TRP according to the RS resource configuration information.

Correspondingly, after the second TRP receives the configuration information of the RS resources, it instructs the victim UEs within its jurisdiction to receive the interventions in the first TRP at all RS resource locations according to the configuration information of all the RS resources allocated to the first TRP. Disturb the RS signal sent by the UE and perform CLI measurement.

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 RS resources to each second TRP, the victim UEs in the second TRP are allocating When receiving the RS signal sent by the scrambling UE in the first TRP on the RS resource for the first TRP, it can be determined according to the received RS signal and the correspondence between the first TRP and the RS resource to which the scrambling UE sending the RS signal belongs The first TRP.

Among them, the RS resources are composed of time domain resources, frequency domain resources, and code domain resources. Different RS resources include time domain resources, frequency domain resources, and code domain resources that are not completely the same.

Then, after the victim UE in the second TRP measures the CLI, the measurement result is quantified to obtain the CLI measurement value. In this way, after the CLI measurement of the victim UE in the second TRP is quantified, any victim UE in the second TRP can 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 victim UE in the second TRP by the CLI of the disturbing UE in the first TRP corresponding to the RS resource when performing downlink services.

In specific implementation, when the victim UE in the second TRP performs CLI measurement and quantifies the CLI measurement value, the CLI applied by the disturbing UE in the first TRP to the victim UE in the second TRP is a physical quantity. The quantified CLI measurement value can accurately represent the strength of the CLI received by the disturbed UE in the second TRP, and the quantized CLI measurement value is usually accurate to 5 or 6 digits after the decimal point.

In this way, when the victim UE in the second TRP reports the CLI measurement results to the second TRP to which it belongs, due to the different system overhead restrictions, the victim UE in the second TRP can use different ones in different situations. The reporting mode reports the CLI measurement result to the second TRP.

Case 1: The system overhead is not limited.

In this case, since the system overhead is not limited, the victim UE in the second TRP can more flexibly select a reporting method from different reporting methods to report the CLI measurement result to the second TRP. The specific reporting methods are not limited to the following.

Reporting method 1: The victim UE in the second TRP directly reports the quantized CLI measurement result of the CLI measurement to the second TRP to which it belongs.

For example, refer to Figure 3 for the scenario. The control range of the dispatch center includes two second TRPs, namely TRP4 and TRP5. The cell corresponding to TRP4 has a victim UE A and a victim UE B, and the cell corresponding to TRP5 has a victim UE C and victim UE D;

The dispatch center also includes 6 first TRPs within the scope of management and control. The corresponding relationship between the first TRP and RS resources is as follows: TRP1~RS1, TRP2~RS2, TRP3~RS3, TRP6~RS4, TRP7~RS5, TRP8~RS6;

And the quantified CLI measurement value after the CLI measurement is set to 6 digits after the decimal point, TRP4 instructs the victim UE A and UE B to perform the CLI measurement, and the victim UE A and the victim UE B in TRP4 are quantified and reported to the CLI The measured values are shown in Table 1:

Table 1

After TRP5 instructs the victim UE C and UE D to perform the CLI measurement, the victim UE C and the victim UE D in TRP5 quantify and report the CLI measurement values as shown in Table 2:

Table 2

Reporting method 2: When the victim UE in the second TRP performs rough measurement, the data after the decimal point is not considered, and the data after the decimal point is processed by rounding to simplify the CLI measurement value.

And the quantified CLI measurement value after the CLI measurement is set to 6 digits after the decimal point, TRP4 instructs the victim UE A and UE B to perform the CLI measurement, and the quantified CLI of the victim UE A and the victim UE B in TRP4 The measured values are shown in Table 1 above, and after TRP5 instructs the victim UE C and UE D to perform CLI measurement, the quantified CLI measurement values of the victim UE C and the victim UE D in TRP5 are shown in Table 2 above;

After simplifying the CLI measurement values measured by the victim UE through the set rules, the CLI measurement values reported by the victim UE A and the victim UE B in TRP4 are shown in Table 3:

table 3

The CLI measurement values reported by the victim UE C and the victim UE D in TRP5 are shown in Table 4:

Table 4

Among them, the second reporting method can only be used in the rough measurement process. This reporting method reduces data complexity at the expense of data accuracy.

Reporting method 3: During rough measurement of the victim UE in the second TRP, by setting multiple levels, the CLI measurement values measured and quantified by the second TRP are mapped to multiple levels, and then each level is represented by the level The degree of CLI interference that the interfering UE in the first TRP exerts on the victim UE in the second TRP.

For example: For example, see Figure 3 for the scenario. The control range of the dispatch center includes two second TRPs, namely TRP4 and TRP5. The cell corresponding to TRP4 has a victim UE A and a victim UE B, and the cell corresponding to TRP5 has The victim UE C and the victim UE D;

In the rough test, the CLI measurement value is divided into five levels according to the set threshold, which are: extremely strong (CLI measurement value>10), strong (8<CLI measurement value ≤10), and medium (5<CLI measurement Value≤8), weak (2<CLI measurement value≤5), extremely weak (CLI measurement value≤2);

After simplifying the CLI measurement values measured by the victim UE through the set rules, the CLI measurement values reported by the victim UE A and the victim UE B in TRP4 are shown in Table 5:

table 5

The CLI measurement values reported by the victim UE C and the victim UE D in TRP5 are shown in Table 6:

Table 6

Further, in the embodiment of the present invention, the five levels divided according to the set threshold can be numericalized, such as: extremely strong-5, strong-4, medium-3, weak-2, extremely weak- -1;

After simplifying the CLI measurement values measured by the victim UE through the set rules, the CLI measurement values reported by the victim UE A and the victim UE B in TRP4 are shown in Table 7:

Table 7

Then the CLI measurement values reported by the victim UE C and the victim UE D in TRP5 are shown in Table 8:

Table 8

Case 2: System overhead is limited.

In this case, in order to save system overhead, the disturbed UE in the second TRP will process the measurement result using a certain arithmetic law, simplify the CLI measurement value and then report it to the second TRP to which it belongs.

During specific implementation, due to different set algorithms for simplified CLI measurement results, there may be multiple reporting methods for reporting the CLI measurement results to the second TRP, which are not limited to the following.

Reporting method 1: When the victim UE in the second TRP performs rough measurement, the data after the decimal point is not considered, and the data after the decimal point is processed by rounding to simplify the CLI measurement value.

In this way, the number of digits of the CLI measurement value reported by the victim UE in the second TRP is reduced, the data complexity is reduced, and the system overhead can be reduced.

Among them, the reporting method under the condition that the system overhead is limited is the same as the reporting method under the condition that the system overhead is not limited. For specific examples, please refer to the example of the above-mentioned method under the condition that the system overhead is not limited. Let me repeat them one by one.

Reporting method 2: During rough measurement of the victim UE in the second TRP, by setting multiple levels, the CLI measurement values measured and quantified by the victim UE in the second TRP are mapped to multiple levels. The pass level indicates the degree of interference of the CLI that the disturbing UE in each first TRP exerts to the disturbed UE in the second TRP.

In this way, the victim UE in the second TRP can map a large amount of data to several fixed levels, reduce the number of digits of the reported CLI measurement value, reduce data complexity, and thereby reduce system overhead.

Among them, the reporting method 2 in the case of limited system overhead is the same as the reporting method 3 in the case of unlimited system overhead.

It should be noted that there are multiple options for simplifying the measurement results reported by the UE. The above-mentioned embodiments are only examples for illustration, and can be flexibly set according to requirements during specific implementation.

After the victim UE in the second TRP reports the CLI measurement result, the second TRP will receive the CLI measurement result reported by the victim UE under its jurisdiction, and report the CLI measurement result to the scheduling center.

In specific implementation, according to whether the second TRP processes the CLI measurement results reported by the victim UE in the second TRP, the second TRP reporting the CLI measurement results to the dispatch center can be divided into two processing methods.

Processing method 1: The second TRP can directly report the CLI measurement results to the dispatch center.

After the victim UE in the second TRP reports the CLI measurement result, the second TRP can directly report the CLI measurement result reported by the victim UE under its jurisdiction to the scheduling center.

Then, after receiving all the CLI measurement results reported by the second TRP, the dispatching center will determine the degree of interference of the CLI that disturbs the UE in each first TRP according to the received CLI measurement results.

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

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

Among them, the scheduling center has different factors for determining the interference weight coefficient of the second TRP, and multiple methods for determining the interference weight coefficient can be determined, which will be described with examples below.

Interference weight coefficient determination method 1: The scheduling center determines the interference weight coefficient of the second TRP according to the number of interfered UEs included in the second TRP.

For example, see Figure 3 for the scenario. The TRPs that can be controlled by the dispatch center include two second TRPs, namely TRP4 and TRP5. The cell corresponding to TRP4 has a victim UE A and a victim UE B, and the cell corresponding to TRP5 has a victim UE. Interfering UE C and Interfering UE D;

If the number of disturbed UEs in TRP4 can be quantified as the interference weight coefficient weight_TRP4, and the number of disturbed UEs in TRP5 can be quantified as the interference weight coefficient weight_TRP5, the values of weight_TRP4 and weight_TRP5 are between 0 and 1, and weight_TRP4+weight_TRP5 = 1, then:

TRP4 interference weight coefficient

TRP5 interference weight coefficient

Interference weight coefficient determination method 2: The dispatch center determines the interference weight coefficient of the second TRP according to the preset system priority of the second TRP.

For example, see Figure 3 for the scenario. The TRP that can be controlled by the dispatch center includes two second TRPs, namely TRP4 and TRP5; the preset system priority levels are 1, 2, and 3, and the system priority value is higher. Larger, the higher the system priority;

Then if the system priority of TRP4 is 3 and the system priority of TRP5 is 1, the system priority of TRP4 can be quantified as the weight coefficient weight_TRP4, and the system priority of TRP5 can be quantified as the weight coefficient weight_TRP5. The values of weight_TRP4 and weight_TRP5 are in Between 0 and 1, and weight_TRP4+weight_TRP5=1, then:

TRP4 interference weight coefficient

TRP5 interference weight coefficient

It should be noted that the system priority of the second TRP can be set according to requirements.

For example, if the area under the jurisdiction of TRP4 is a hotspot priority coverage area, and the area under the jurisdiction of TRP5 is an ordinary residential building, the system priority of TRP4 can be set higher than that of TRP5;

If the area under the jurisdiction of TRP4 is a residential area, and the area under the jurisdiction of TRP5 is an industrial park, the system priority of TRP4 can be set higher than that of TRP5.

Interference weight coefficient determination method 3: The dispatch center determines the interference weight coefficient of the second TRP according to the number of interfered UEs included in the second TRP and the preset system priority of the second TRP.

For example, see Figure 3 for the scenario. The TRPs that can be controlled by the scheduling center include two second TRPs, namely TRP4 and TRP5. The cell corresponding to TRP4 has a victim UE A and a victim UE B, and the cell corresponding to TRP5 has a victim UE. Interfering UE C and victim UE D; and the preset system priority has three levels 1, 2, and 3. The higher the system priority value, the higher the system priority;

Then if the system priority of TRP4 is 2 and the system priority of TRP5 is 3, the number of UEs and system priority of TRP4 can be quantified as weight coefficient weight_TRP4, and the number of UEs and system priority of TRP5 can be quantified as weight coefficient weight_TRP5, weight_TRP4 The value of weight_TRP5 is between 0 and 1, and weight_TRP4+weight_TRP5=1, then:

TRP4 interference weight coefficient

TRP5 interference weight coefficient

In addition, the dispatch center can also record the interference weight coefficient of the second TRP calculated every time when the interference weight coefficient of the second TRP is used, and after obtaining enough historical data, perform statistical analysis based on the recorded historical data to obtain The relationship between the specific weight value setting and the final system performance, and then select the best according to the system performance.

It should be noted that the foregoing only lists several schemes that can be used to determine the weight coefficient. During specific implementation, it can be flexibly set according to specific requirements, which is not limited in the embodiment of the present invention.

After determining the interference weight coefficient of the second TRP, the scheduling center will determine the interference degree of the CLI of the interfering 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 uses the weighted average of the CLI measurement values measured by the victim UE in each second TRP as the interference degree of the CLI of the disturbing UE in the first TRP.

For example, see Figure 3 for the scenario. For the convenience of calculation and description, the following CLI measurement values directly use positive integers for illustration;

Among them, the TRP that the scheduling center can control includes two second TRPs, namely TRP4 and TRP5. The cell corresponding to TRP4 has a victim UE A and a victim UE B, and the interference weight coefficient corresponding to TRP4 is 0.5;

There are a victim UE C and a victim UE D in the cell corresponding to TRP5, and the interference weight coefficient corresponding to TRP5 is also 0.5.

If the CLI measurement result directly reported by the second TRP received by the dispatch center is shown in Table 8:

Table 8

In this way, the interference level of the CLI that disturbs the UE in TRP1:

The interference level of the CLI that disturbs the UE in TRP2:

The interference level of the CLI that disturbs the UE in TRP3:

The interference level of the CLI that disturbs the UE in TRP6:

The interference level of the CLI that disturbs the UE in TRP7:

The interference level of the CLI that disturbs the UE in TRP8:

That is, the CLI interference degree of the interfering UE in each first TRP determined by the scheduling center is shown in Table 9:

Table 9

Processing manner 2: The second TRP performs integration processing according to the CLI measurement results reported by the victim UE in the second TRP, and then reports the integrated CLI measurement results to the dispatch center.

In specific implementation, for any RS resource, the second TRP determines the average value according to the CLI measurement value corresponding to the RS resource reported by each victim UE, and the average value indicates that the victim UE in the second TRP receives the RS. The interference level of the CLI applied by the interfering UE in the first TRP corresponding to the resource.

For example, see Figure 3 for the scenario. The TRPs that can be controlled by the scheduling center include two second TRPs, namely TRP4 and TRP5. The cell corresponding to TRP4 has a victim UE A and a victim UE B, and the cell corresponding to TRP5 has a victim UE. Interfering UE C and victim UE D, if the CLI measurement values reported by the victim UE A and the victim UE B in TRP4, and the CLI measurement values reported by the victim UE C and the victim UE D in TRP5 are as shown in Table 8 above It is shown that the second TRP uses the above calculation rules to integrate the CLI measurement values reported by the victim UE under its jurisdiction, and the CLI measurement results obtained are shown in Table 10:

Table 10

Then the second TRP reports the integrated CLI measurement result to the dispatching center, and the dispatching center determines the interference degree of the CLI that disturbs the UE in each first TRP according to the received CLI measurement result.

The method for the scheduling center to determine the interference weight coefficient of the second TRP is the same as the method for the scheduling center to determine the interference weight coefficient of the second TRP when the second TRP directly reports the CLI measurement results reported by the victim UE under its jurisdiction. The second TRP directly reports the part of the CLI measurement results reported by the victim UE under its jurisdiction, so it will not be repeated one by one.

Among them, the TRP that can be controlled by the scheduling center includes two second TRPs, namely TRP4 and TRP5. There are a victim UE A and a victim UE B in the cell corresponding to TRP4, and the interference weight coefficient corresponding to TRP4 is 0.5;

The interference weight coefficient corresponding to TRP4 is 0.6, and the interference weight coefficient corresponding to TRP5 is also 0.4. If the integrated CLI measurement result reported by the second TRP received by the dispatch center is shown in Table 9, then:

The interference level of the CLI that disturbs the UE in TRP1: = (5×0.6+4×0.4)×0.5=2.3;

The interference level of the CLI that disturbs the UE in TRP2: = (9×0.6+7×0.4)×0.5=4.1;

The interference level of the CLI that disturbs the UE in TRP3: = (11×0.6+13×0.4)×0.5=5.9;

The interference level of the CLI that disturbs the UE in TRP6: = (3.5×0.6+3×0.4)×0.5=1.65;

The interference level of the CLI that disturbs the UE in TRP7: = (2×0.6+4×0.4)×0.5=1.4;

The interference level of the CLI that disturbs the UE in TRP8: = (1×0.6+2×0.4)×0.5=0.7.

That is, the CLI interference degree of each disturbing UE in the first TRP to the disturbed UE in the second TRP within the control range of the scheduling center is shown in Table 11 below:

Table 11

It should be noted that there can be multiple functions that indicate the degree of interference of the CLI that the interfering UE in the first TRP imposes on the interfered UE within the control range of the scheduling center. The above only lists one possible implementation. The specific implementation In the process, the function relationship can be set independently according to the demand.

After the dispatching center determines the degree of interference that the interfering UE in the first TRP exerts on the CLI of the disturbed UE within the control range of the dispatching center, it will determine the interference of the disturbing UE in the first TRP to the disturbed UE within the control range of the dispatching center. The degree of CLI interference applied by the disturbing UE and the preset CLI interference intensity difference threshold determine whether to perform fine measurement.

2. As shown in Figure 4, the CLI fine measurement stage.

In specific implementation, the dispatch center first determines the interference difference coefficient according to the degree of interference of the CLI that the interfering UE in each first TRP exerts on the interfered UE within the control range of the dispatch center;

Then the interference difference coefficient is compared with the preset CLI interference degree difference threshold, and when the interference difference coefficient is greater than the preset CLI interference degree difference threshold, it is determined that fine measurement is required;

Otherwise, it is determined that no fine measurement is required.

In specific implementation, the scheduling center first needs to determine the interference difference coefficient according to the determined interference degree of the CLI that the interfering UE in the first TRP exerts on the interfered UE within the control range of the scheduling center.

Among them, there are many ways to determine the interference difference coefficient according to the different set parameters representing the interference difference coefficient, which will be described below with examples.

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

For example, referring to FIG. 4 for the scenario, the CLI interference degree of the disturbing UE in the first TRP finally determined by the dispatching center to the disturbed UE in the second TRP within the control range of the dispatching center is shown in Table 9.

When determining the maximum difference coefficient, the scheduling center determines that the maximum value of the CLI interference degree of the disturbing UE in the first TRP to the disturbed UE in the second TRP within the control range of the dispatch center is 12;

The minimum value of the CLI interference degree that the interfering UE in the first TRP exerts to the interfered UE in the second TRP within the control range of the scheduling center is 1.5;

Finally, the dispatch center determines the interference difference coefficient=12-1.5=11.5 according to the set rules.

(2) The maximum difference coefficient is the variance of the CLI interference level applied by the disturbing UE in each first TRP to the disturbed UE in the scheduling center.

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

Finally, the dispatch center determines the interference difference coefficient according to the set rules = ((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.

(3) The maximum difference coefficient is the standard deviation of the interference degree of CLI applied by the disturbing UE in each first TRP to the disturbed UE in the scheduling center.

The variance of the CLI interference degree applied by the interfering UE in each first TRP to the interfered UE in the second TRP within 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 dispatch center determines the interference difference according to the set rules

Subsequently, the scheduling center compares the determined interference difference coefficient with a preset interference degree difference threshold to determine whether to reconfigure the RS resources.

For example, the scheduling center may use the difference between the maximum value of the CLI interference degree and the minimum value of the interference degree applied by the interfering UE in the first TRP to the interfered UE within the control range of the scheduling center as the interference difference coefficient, and set The interference degree difference threshold is 5, and the determined interference degree of the interfering UE in the first TRP to the CLI of the interfered UE within the control range of the scheduling center is as shown in Table 9 above:

Then the dispatch 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 dispatch center determines that fine measurement is required.

After the dispatching center determines that fine measurement is required, it will reconfigure RS resources for the first TRP.

In the specific implementation process, in order to more accurately measure the interference level of the CLI of the interfering UE in the first TRP, the scheduling center allocates more information to the first TRP with strong CLI interference caused by the interfering UE to the victim UE. Multiple RS resources enable the interfering UE in the first TRP to perform CLI measurements with higher accuracy.

After determining that RS resources need to be reconfigured, the scheduling center can set the rules for reconfiguring RS resources for the first TRP according to specific requirements. In this way, according to the preset rules for reconfiguring RS resources for the first TRP, how many The methods for allocating RS resources are not limited to the following.

RS resource reconfiguration method one

In specific implementation, the scheduling center compares the determined interference level of the CLI of the interfering UE in each first TRP with the set interference threshold, and when the interference level is greater than the set interference threshold, assigns the first TRP RS resources with the same number of interfering UEs in the first TRP;

When the degree of interference is not greater than the set interference threshold, one RS resource is allocated to the first TRP.

For example, when the scheduling center uses the difference between the maximum value of the CLI interference degree and the minimum value of the interference degree applied by the interfering UE in the first TRP to the interfered UE within the control range of the scheduling center as the interference difference coefficient, the interference degree difference The threshold value is 5, the interference threshold value is 6, and the determined interference degree of the interfering UE in the first TRP to the CLI of the disturbed UE within the control range of the scheduling center is shown in Table 9 above, then the scheduling center calculates the interference difference coefficient Obtain: 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 dispatch center determines that fine measurement is needed;

Subsequently, the scheduling neutral line compares the interference level of the CLI of the disturbing UE in each first TRP with the set interference threshold, and determines the CLI that the disturbing UE in TRP2 and TRP3 applies to the disturbed UE in the second TRP The interference degree is greater than the set interference degree threshold, and the scheduling center allocates the same number of RS resources as the interfering UEs in TRP2 and TRP3 during fine measurement;

At the same time, the dispatch center allocates one RS resource to TRP1 and TRP6 to TRP7 during fine measurement.

RS resource reconfiguration method two

In specific implementation, the dispatch center divides the first TRP into four levels according to the set three interference thresholds: strong (CLI measurement value>10), medium (7<CLI measurement value ≤10), and weak (3<CLI measurement value) Value≤7), extremely weak (CLI measurement value≤3);

When the determined CLI interference level of the interfering UE in the first TRP belongs to the "strong" level, the scheduling center allocates the same number of RSs as the interfering UEs in the first TRP when performing fine measurement. Resources;

When the determined level of interference of the CLI of the interfering UE in the first TRP belongs to the "medium" level, the scheduling center allocates at least one RS resource for the first TRP when performing fine measurement, and each RS resource Correspond to at least two interfering UEs;

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

When it is determined that the interference level of the CLI of the interfering UE in the first TRP belongs to the "very weak" level, the scheduling center does not allocate RS resources to the first TRP when performing fine measurement. TRP does not participate in CLI fine measurement.

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

And the range of TRP2 includes 4 interfering UEs (UE a, UE b, UE c, UE d), and the range of TRP3 includes 3 interfering UEs (UE1, UE2, UE3);

And when the interference level of the CLI of the interfering UE in the first TRP belongs to the "medium" level, every two UEs share one RS resource;

And the determined interference degree of the interfering UE in the first TRP to the CLI of the interfered UE within the control range of the scheduling center is as shown in Table 9 above, then the scheduling center calculates the interference difference coefficient to obtain: 12-1.5=10.5;

Subsequently, the scheduling neutral line compares the interference level of the CLI of the interfering UE in each first TRP with the set interference threshold, and determines:

The interference level of the CLI that the interfering UE in TRP3 exerts to the victim UE in the second TRP is greater than 10, which belongs to the "strong" level. The scheduling center allocates the same number of interfering UEs to TRP3 during fine measurement. RS resources, that is, RS1 is allocated to UE1 in TRP3, RS2 is allocated to UE2 in TRP3, and RS3 is allocated to UE3 in TRP3;

The interference level of the CLI that the interfering UE in TRP2 exerts to the victim UE in the second TRP is greater than 7 and less than 10, which belongs to the "medium" level. The scheduling center allocates 2 RS resources for TRP2 during fine measurement; For example, RS4 and RS5 are allocated to TRP2, UE a and UE b in TRP2 share RS resource 4, and UE c and UE d in TRP2 share RS resource 4;

The interference level of the CLI that the interfering UE in TRP1 exerts to the victim UE in the second TRP is greater than 4 and less than 7, which belongs to the "weak" level. The scheduling center allocates 1 RS resource for TRP1 during fine measurement. If RS6 is allocated to TRP1, the interfering UEs in TRP1 share RS6;

The interference level of the CLI that the interfering UE in TRP6, TRP7, and TRP8 exerts to the victim UE in the second TRP is less than 4, and the scheduling center does not allocate RS resources to TRP6, TRP7, and TRP8.

After the scheduling center determines the RS resources for fine measurement, it will resend the configuration information of the RS resources to the first TRP and the second TRP respectively.

In specific facts, the processing method when the scheduling center sends the configuration information of the RS resources to the first TRP and the second TRP respectively, and the CLI measurement performed by the victim UE in the second TRP and the quantified CLI measurement value is consistent with the rough measurement. Therefore, I will not repeat them one by one.

Finally, the measurement result of the CLI measurement reported by the victim UE in the second TRP is shown in the following table.

For example, referring to Figure 4 for the scenario, RS resource reconfiguration method 2 is used to perform RS resource reconfiguration for the first TRP, and to facilitate calculation and description, the following CLI measurement values directly use positive integers for illustration;

After the scheduling center reconfigures the RS resources for the first TRP, the correspondence between the first TRP and the RS resources 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-TRP1;

The quantified and reported CLI measurement values of the victim UE C and the victim UE D in TRP4 are shown in Table 12 below:

Table 12

The quantified and reported CLI measurement values of the victim UE C and the victim UE D in TRP5 are shown in Table 13 below:

Table 13

Subsequently, the victim UE in the second TRP adds the measurement result of the CLI measurement to the second TRP to which it belongs.

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

After the victim UE reports the CLI measurement result, the second TRP will receive the CLI measurement result reported by the victim UE under its jurisdiction, and report the CLI measurement result to the scheduling center.

In fine measurement, the second TRP receives and reports the CLI measurement results reported by the interfered UE under its own jurisdiction, and the scheduling center determines the interference level obtained by the CLI measurement corresponding to each RS resource. The process is the same as the coarse measurement. Let me repeat them one by one.

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

Among them, the scheduling center performs CLIM rules according to the interference level of the CLI of the interfering UE in the first TRP obtained after fine measurement. The CLIM rules can be specifically set according to specific requirements. In this way, according to the preset CLIM rules, there are multiple Different CLIM ways.

CLIM mode one for dispatch center

The scheduling center presets the adjustment threshold for CLIM, and when the interference level obtained by the fine measurement is greater than the adjustment threshold, instructs to adjust the transmit power of the interfering UE in the first TRP corresponding to the interference level;

When the interference level obtained by the fine measurement is not greater than the adjustment threshold, the first TRP corresponding to the interference level and the interfering UE in the first TRP corresponding to the interference level are instructed to perform data transmission.

For example, see 4 for the scenario and set 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, and RS4 is allocated to UEa and UEb in TRP2, RS5 It is allocated to UEc and UEd in TRP2, and RS6 is allocated to TRP1, and the CLI measurement results reported by the scheduling center according to the victim UE in the second TRP are shown in Table 14 below:

Table 14

According to the set adjustment threshold, it can be seen that the interference intensity of UE L in TRP3 corresponding to RS3 is greater than the set fourth interference threshold, so the scheduling center instructs TRP3 to reduce the transmit power of UE3 to reduce the interference of UE3 in TRP3. CLI applied by the disturbed UE in the center;

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

CLIM mode 2 for dispatch center

The dispatch center can also subdivide the adjustment threshold, for example, set three adjustment thresholds, namely: 8, 5, and 2;

When the interference level determined by the fine measurement is greater than 8, it can be determined that the interfering UE corresponding to the interference level causes a great CLI to the interfered UE within the control range of the scheduling center, which has seriously affected the downlink service of the interfered UE. Consider avoiding scheduled transmission and suspend the downlink service of the disturbed UE.

When the interference level determined by the fine measurement is greater than 5 and less than 8, it can be determined that the interfering UE corresponding to the interference level causes a large CLI to the disturbed UE within the control range of the scheduling center, and the scheduling center instructs to reduce the level corresponding to the interference level. The transmit power of the disturbing UE in the first TRP;

When the interference level determined by the fine measurement is greater than 2 and less than 5, it can be determined that the interfering UE corresponding to the interference level causes a small CLI to the disturbed UE within the control range of the scheduling center, indicating the first TRP and the corresponding interference level. The interfering UE in the first TRP corresponding to the interference level performs data transmission;

When the interference level determined by the fine measurement is less than 2, it can be determined that the interfering UE corresponding to the interference level causes extremely small CLI to the interfered UE within the control range of the scheduling center, and it can be instructed to increase the first corresponding to the interference level appropriately. The transmit power of the disturbing UE in the TRP, so that the disturbing UE can better perform uplink service transmission.

For example, see Figure 4 for the scene, and set three adjustment thresholds, namely: 8, 5, and 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 UEc and UEd in TRP2. After TRP1, and the CLI measurement results reported by the disturbed UE in the second TRP by the dispatch center are shown in Table 15 below:

Table 15

According to the set adjustment threshold, it can be known that the interference intensity of UE L in TRP3 corresponding to RS3 is greater than 5 and less than 8, and the scheduling center instructs TRP3 to reduce the transmit power of UE3, so as to reduce the interference of UE3 in TRP3 to the scheduling center. CLI applied by the victim UE;

The CLI corresponding to RS1 and RS2 are both greater than 2 and less than 5, then TRP3 directly transmits uplink data with UE1 and UE2, without adjusting the transmit power of UE1 in TRP3 and the transmit power of UE2 in TRP3;

The CLI corresponding to RS4 is both greater than 2 and less than 5, then TRP2 and UEc and UEd directly perform uplink data transmission without adjusting the transmit power of UEc and UEd in TRP2

The CLI corresponding to RS6 is greater than 2 and less than 5, then TRP1 and all the interfering UEs in TRP1 perform uplink data transmission, and the transmit power of all the interfering UEs in TRP1 is not adjusted;

If the CLI corresponding to RS4 is all less than 2, the scheduling center can instruct TRP2 to appropriately increase the transmit power of UEa and UEb to improve the quality of the uplink transmission services of UEa and UEb.

As shown in Figure 5, in the embodiment of the present invention, the time for completing a rough measurement can be regarded as the CLI short measurement period, and the time for completing a rough measurement and a fine measurement can be regarded as the CLI long measurement period. Thus, in a CLI long measurement The period includes at least two CLI short measurement periods.

Among them, after the RS resources of one CLI long measurement period are removed from the RS resources of one CLI short measurement period used for coarse measurement, the remaining RS resources should be greater than or equal to the RS resources required for fine measurement.

As shown in FIG. 6, a detailed flowchart of a method for configuring CLI measurement resources in an embodiment of the present application.

Degree of interference

Step 606: The scheduling center determines the interference difference coefficient according to the degree of interference of the CLI that the interfering UE in the first TRP exerts to the interfered UE within the control range of the scheduling center;

Step 608: The scheduling center reconfigures RS resources for the first TRP according to the degree of interference.

Step 609, the first TRP and the second TRP perform CLI fine measurement on the configured RS resources;

Step 6010: The second TRP receives the CLI measurement result of the CLI fine measurement reported by the victim UE, and reports the CLI measurement result to the dispatch center;

Step 6011: The dispatch center determines the CLI value applied by the disturbing UE in the first TRP to the disturbed UE within the control range of the dispatch center according to the received CLI measurement result and the determined weight coefficient of the second TRP corresponding to the first TRP. Degree of interference

Step 6012: The dispatching center instructs the first TRP to perform CLIM according to the degree of interference of the CLI applied by the disturbing UE in the first TRP to the disturbed UE within the control range of the dispatching center.
