With the rapid development of the mobile internet and the evolution of New terminal forms, the demands of mobile data services such as smart home, smart city, telemedicine and the like are explosively increased, and a 5G (fifth generation mobile communication technology) NR (New Radio) network has been developed.

In the current 5G application system, the base station obtains uplink channel information according to the uplink transmission signal, and obtains downlink channel information based on channel reciprocity. Therefore, by using the uplink signal estimation error, non-ideal factors such as the accuracy of uplink measurement and the like can influence the precoding performance based on channel reciprocity. And uplink timing synchronization measurement based on SRS (Sounding Reference Signal, channel sounding reference signal) is used in a tracking phase of the uplink timing to measure uplink timing offset. The SNR (Signal and Noise Ratio, signal-to-noise ratio) based on SRS can be used to estimate the uplink channel quality, antenna selection, channel estimation, and if the SNR estimation of SRS is inaccurate, the performance state of the entire uplink and downlink can be affected. At present, the laboratory and the real networking environment are complex, and each terminal continuously moves under the coverage area of the network, so that the problem of inaccurate SRS measurement exists, and the problem of inaccurate SRS measurement needs to be positioned aiming at the scene.

In the related art, when the problem of inaccurate SRS measurement is found and the problem is located, the problem is generally analyzed by blindly grasping uplink frequency domain data and based on the grasped data. The solution is not able to meet the fast, efficient, accurate test requirements regarding SRS measurement inaccuracy problems.

Detailed Description

The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

The following describes a method for capturing abnormal SRS data according to the embodiment of the present application with reference to the accompanying drawings.

Fig. 1 is a flowchart of a method for capturing abnormal SRS data according to an embodiment of the present application, where the method of the embodiment of the present application may be used in a base station, as shown in fig. 1, and the method includes:

step 101, determining the current grabbing condition under the condition that the TA adjusting function is started.

The method is used for grabbing abnormal SRS data. When the base station grabs abnormal SRS data, whether the TA adjusting function is started or not can be determined, and under the condition that the TA adjusting function is started, the current grabbing condition can be determined.

The current grabbing conditions are determined according to the current testing scene, and different grabbing conditions can be corresponding to different testing scenes to ensure testing accuracy.

The current grabbing condition is any one of the following conditions: IRT fixed value, IRT difference, SNR fixed value, SNR threshold value, SNR difference.

Step 102, determining a current target monitoring value according to the current grabbing condition.

In the embodiment of the application, the corresponding relation between the grabbing condition and the monitoring item is preset, the base station determines the monitoring item according to the current grabbing condition and the corresponding relation, and detects according to the monitoring item to determine the current target monitoring value. Optionally, the preset grabbing conditions are multiple, and the grabbing conditions are set corresponding to the monitoring items. The current grabbing conditions are different, and the current monitoring items to be monitored are different.

Wherein the target monitoring value includes any one of the following: the difference between the IRT value of the current period and the IRT value of the previous period, the difference between the SNR value of the current period and the SNR value of the previous period, the IRT value of the current period and the SNR value of the current period.

As an example, the current grabbing condition is an IRT fixed value, and the corresponding target monitoring value is: IRT value for the current period.

As another example, the current grabbing condition is IRT difference, and the corresponding target monitoring value is: the difference between the IRT value of the current cycle and the IRT value of the previous cycle.

As another example, the current grabbing condition is a fixed SNR value, and the corresponding target monitored value is: SNR value of the current period.

As another example, the current grabbing condition is an SNR threshold value, and the corresponding target monitoring value is: SNR value of the current period.

As another example, the current grabbing condition is SNR difference, and the corresponding target monitoring value is: the difference between the SNR value of the current period and the SNR value of the previous period.

And step 103, grabbing abnormal SRS data under the condition that the target monitoring value is matched with the grabbing condition.

In this embodiment, the base station may buffer SRS data in each period, and determine whether to grab abnormal SRS data according to whether the target monitoring value matches the grabbing condition. For example, after determining the current target monitoring value, the base station matches the target monitoring value with the grabbing condition, grabs abnormal SRS data if the target monitoring value matches with the grabbing condition, and does not grab abnormal SRS data if the target monitoring value does not match with the grabbing condition.

The method comprises the steps of judging whether a target monitoring value is matched with a grabbing condition or not according to the grabbing condition. For example, matching the target monitor value to the grabbing condition may include: the target monitoring value is the same as the grabbing condition, and the target monitoring value belongs to a preset range.

According to the method for capturing abnormal channel Sounding Reference Signal (SRS) data, under the condition that the Timing Advance (TA) adjustment function is started, the current capturing condition is determined, the current target monitoring value is determined according to the current capturing condition, and further, under the condition that the target monitoring value is matched with the capturing condition, abnormal SRS data are captured. Therefore, the abnormal data can be quickly captured aiming at the problem of inaccurate SRS measurement in different scenes, and the data capturing efficiency and the accuracy of abnormal data acquisition are improved. And can be aimed at the targeted useful data of snatching of different scenes, and then can effectively improve problem location efficiency, further improve the stability of basic station product.

In one embodiment of the present application, the current grabbing condition is an IRT difference value, and a method for grabbing abnormal SRS data in the embodiment of the present application is described below with reference to fig. 2 and the grabbing condition. Fig. 2 is a flowchart of another method for capturing SRS data of an abnormal channel sounding reference signal according to an embodiment of the present application, as shown in fig. 2, where the method includes:

In step 201, when the TA adjustment function is turned on, the current grabbing condition is determined.

The current grabbing condition is IRT difference value. For example, the grabbing condition is that in the case of turning on the TA adjustment function, the IRT takes on the value range of [ -16, 16] in two SRS periods, that is, the value range of the difference between two IRT values is [ -32, 32], and the absolute value of the difference takes on the value range of [0, 32], where the IRT unit is 1.

Step 202, obtaining the IRT value of the current period and the IRT value of the previous period adjacent to the current period.

In this embodiment, the IRT value of the current period is obtained, and the IRT value of the previous period adjacent to the current period is obtained, where the period may be an SRS period. For example, for a first period and a second period that are adjacent to each other, wherein the second period is used as a current period, the first period is a previous period that is adjacent to the second period, SRS data is buffered and IRT values are acquired during the first period, and IRT values are acquired during the second period. Optionally, SRS data may also be buffered at the second period.

Step 203, determining the difference between the IRT value of the current period and the IRT value of the previous period as the current target monitoring value.

Optionally, the target monitoring value is determined by: irt_diff=irt_front_irt_back, wherein irt_front is an IRT preamble value of the current period, irt_back is a corresponding IRT value of the adjacent period, and irt_diff is a target monitoring value.

And step 204, grabbing the SRS data of the current period and the SRS data of the previous period under the condition that the target monitoring value is the same as the grabbing condition.

As an example, when the irt_diff value is equal to the grabbing condition when the irt_diff value is [0,32], the SRS data of the current period and the SRS data of the previous period are grabbed, specifically, the SRS time-frequency domain data conforming to the condition is grabbed in the two adjacent SRS periods. Optionally, if the target monitoring value and the grabbing condition are different in two adjacent periods, the next adjacent period is recycled.

Note that the above description of determining whether the target monitor value is the same as the gripping condition is merely an example, and is not particularly limited herein.

Therefore, in the embodiment of the application, the grabbing of the abnormal SRS data can be triggered by the IRT difference value, the problem occurrence moment can be accurately positioned, and the subsequent data analysis efficiency is improved.

In one embodiment of the present application, the current grabbing condition is an SNR difference value, and a method for grabbing abnormal SRS data in the embodiment of the present application is described below with reference to fig. 3 and the grabbing condition. Fig. 3 is a flowchart of another method for capturing SRS data of an abnormal channel sounding reference signal according to an embodiment of the present application, as shown in fig. 3, where the method includes:

Step 301, determining a current grabbing condition when the TA adjustment function is turned on.

Wherein the current grabbing condition is an SNR difference value. For example, the grabbing condition is that in the case of turning on the TA adjustment function, the SNR value ranges from [ -15, 40] in two SRS periods, that is, the difference value between two SNR values ranges from [ -55, 55], where the SNR unit is 1db.

Step 302, obtaining the SNR value of the current period and the SNR value of the previous period adjacent to the current period.

In this embodiment, an SNR value of a current period is obtained, and an SNR value of a previous period adjacent to the current period is obtained, where the period may be an SRS period. For example, for a first period and a second period that are adjacent to each other, wherein the second period is the current period, the first period is a previous period that is adjacent to the second period, SRS data is buffered and SNR values are acquired in the first period, and SNR values are acquired in the second period. Optionally, SRS data may also be buffered at the second period.

Step 303, determining the difference between the SNR value of the current period and the SNR value of the previous period as the current target monitor value.

Optionally, the target monitoring value is determined by: snr_diff=snr_front_snr_back, where snr_front is the SNR preamble value of the current period, snr_back is the corresponding SNR value of the adjacent period, and snr_diff is the target monitored value.

And step 304, grabbing the SRS data of the current period and the SRS data of the previous period under the condition that the target monitoring value is the same as the grabbing condition.

As an example, when the snr_diff is equal to [ -55,55], if the target monitor value is determined to be the same as the grabbing condition, the SRS data of the current period and the SRS data of the previous period are grabbed, specifically, the SRS time-frequency domain data conforming to the condition is grabbed in the two adjacent SRS periods. Optionally, if the target monitoring value and the grabbing condition are different in two adjacent periods, the next adjacent period is recycled.

Therefore, in the embodiment of the application, the grabbing of the abnormal SRS data can be triggered through the SNR difference value, the problem occurrence time can be accurately positioned, and the subsequent data analysis efficiency is improved.

In one embodiment of the present application, the current grabbing condition is an IRT fixed value, and a method for grabbing abnormal SRS data in the embodiment of the present application is described below with reference to fig. 4 and the grabbing condition. Fig. 4 is a flowchart of another method for capturing SRS data of an abnormal channel sounding reference signal according to the embodiment of the present application, as shown in fig. 4, where the method includes:

in step 401, in the case where the TA adjustment function is turned on, the current grabbing condition is determined.

The current grabbing condition is an IRT fixed value. For example, the grabbing condition is that the IRT takes on a value range of [ -16,16] in one SRS period when the TA adjustment function is turned on, where the IRT unit is 1.

Step 402, determining the IRT value of the current period as the current target monitoring value.

In this embodiment, the IRT value of the current period is obtained, where the period may be an SRS period.

And step 403, grabbing the SRS data of the current period under the condition that the target monitoring value is the same as the grabbing condition.

As an example, if the target monitoring value is irt_fix, and if the irt_fix is [ -16,16], it is determined that the target monitoring value is the same as the fixed value of the grabbing condition IRT, and the SRS data of the current period is grabbed, specifically, the SRS time-frequency domain data meeting the condition is grabbed in the current SRS period. Optionally, if the target monitoring value and the grabbing condition are different in the current period, the method loops to the next period.

Therefore, in the embodiment of the application, the grabbing of the abnormal SRS data can be triggered by the IRT fixed value, the problem occurrence time can be accurately positioned, and the subsequent data analysis efficiency is improved.

In one embodiment of the present application, the current grabbing condition is a fixed SNR value, and a method for grabbing abnormal SRS data in the embodiment of the present application is described below with reference to fig. 5 and the grabbing condition. Fig. 5 is a flowchart of another method for capturing SRS data of an abnormal channel sounding reference signal according to an embodiment of the present application, as shown in fig. 5, where the method includes:

In step 501, in the case where the TA adjustment function is turned on, the current grabbing condition is determined.

Wherein the current grabbing condition is an SNR fixed value. For example, the grabbing condition is that the SNR value range is [ -15,40] and the SNR unit is 1db in one SRS period when the TA adjustment function is started.

In step 501, the SNR value of the current period is determined as the current target monitor value.

In this embodiment, an SNR value of a current period is obtained, where the period may be an SRS period.

And step 503, grabbing SRS data of the current period under the condition that the target monitoring value is the same as the grabbing condition.

As an example, if the target monitor value is denoted as snr_fix and the snr_fix is equal to the grabbing condition SNR fixed value, the SRS data of the current period is grabbed, specifically, the SRS time-frequency domain data meeting the condition is grabbed in the current SRS period. Optionally, if the target monitoring value and the grabbing condition are different in the current period, the method loops to the next period.

Therefore, in the embodiment of the application, the grabbing of the abnormal SRS data can be triggered by the SNR fixed value, the problem occurrence time can be accurately positioned, and the subsequent data analysis efficiency is improved.

In one embodiment of the present application, the current grabbing condition is an SNR threshold value, and a method for grabbing abnormal SRS data in the embodiment of the present application is described below with reference to fig. 6 and the grabbing condition. Fig. 6 is a flowchart of another method for capturing SRS data of an abnormal channel sounding reference signal according to the embodiment of the present application, as shown in fig. 6, where the method includes:

in step 601, when the TA adjustment function is turned on, the current grabbing condition is determined.

Wherein the current grabbing condition is an SNR threshold. For example, the grabbing condition is that the SNR value range is [ -15, 40] in the same SRS period when the TA adjustment function is turned on, wherein the SNR unit is 1db.

Step 602, determining the SNR value of the current period as the current target monitoring value.

In step 603, the SRS data of the current period is grabbed when the SNR value of the current period is greater than or equal to the SNR maximum threshold value or less than or equal to the SNR minimum threshold value.

In this embodiment, if the target monitoring value is greater than or equal to the SNR maximum threshold value, the abnormal SPS data capture is triggered, and if the target monitoring value is less than or equal to the SNR minimum threshold value, the abnormal SPS data capture is triggered. The maximum SNR threshold and the minimum SNR threshold may be determined according to specific grabbing conditions, and the maximum threshold may be greater than the minimum threshold. Optionally, if there is no eligible data in the current SRS period, then loop to the next period.

Therefore, in the embodiment of the application, the grabbing of the abnormal SRS data can be triggered through the SNR threshold value, the problem occurrence time can be accurately positioned, and the subsequent data analysis efficiency is improved.

Based on the above embodiments, the following description is made in connection with the actual application scenario.

Step two: determining whether the grabbing condition is an SNR fixed value or an SNR difference value or an SNR threshold value, and grabbing abnormal SRS data according to the SNR fixed value if the grabbing condition is the SNR fixed value; if the SRS data are the SNR difference values, the abnormal SRS data are grabbed according to the SNR difference values; if the SRS data is the SNR threshold, the abnormal SRS data is captured according to the SNR threshold, otherwise, the step III is entered.
