[0052] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0053] The following combination Figures 1-5 The CSIRS frequency band adaptive adjustment method of the present invention is described, which is characterized by comprising:

[0054] S100: Acquire CSIRS information and scheduling information according to a preset statistical period, wherein the CSIRS information includes a time domain symbol and a resource block sequence corresponding to each CSIRS, and the scheduling information reflects information on user scheduling of the CSIRS;

[0055] S200: Acquire, according to the scheduling information, the number of successfully scheduled users and the number of resource blocks occupied by the users corresponding to each of the time domain symbols;

[0056] S300: Inputting the CSIRS information and the scheduling information into a preset processing model to obtain an estimated number of users and an estimated number of occupied resource blocks corresponding to each time domain symbol;

[0057] S400: Adjusting a CSIRS occupied frequency band according to the number of successfully scheduled users, the number of resource blocks occupied by the users, the estimated number of users, and the estimated number of occupied resource blocks;

[0058] Among them, the number of successfully scheduled users reflects the number of users who have successfully scheduled CSIRS, the number of resource blocks occupied by users reflects the number of resource blocks occupied by CSIRS scheduled by users, the estimated number of users reflects the number of users who schedule CSIRS after the preset time, the estimated number of occupied resource blocks reflects the number of resource blocks occupied by CSIRS scheduled by users after the preset time, and the CSIRS occupied frequency band reflects the frequency bandwidth occupied by CSIRS or the occupied resource block sequence.

[0059] According to the CSIRS information, the time domain symbol and the resource block sequence corresponding to each CSIRS are known, and according to the scheduling information, the association information of the user scheduling CSIRS is known, the number of successfully scheduled users corresponding to each time domain symbol is determined, and the number of resource blocks occupied by the corresponding users is determined. The CSIRS information and the scheduling information are processed by using the processing model to estimate the number of users scheduled by the CSIRS and the corresponding occupied resource blocks after a predetermined time, that is, the estimated number of users and the estimated occupied resource blocks. According to the estimated number of users and the estimated occupied resource blocks, the demand change trend of the CSIRS can be predicted, and the occupied frequency band of the CSIRS is adjusted in combination with the current number of successfully scheduled users and the number of resource blocks occupied by the users, so that the occupied frequency band of the CSIRS is dynamically adjusted with the change of user demand, and on the basis of meeting the demand of the CSIRS of the user service, the effect of adaptively and dynamically adjusting the occupied frequency band of the CSIRS is achieved. When the user demand decreases, the occupied frequency band of the CSIRS is reduced, which is beneficial to release the idle time-frequency domain resources and improve the resource utilization rate of the wireless base station, and the energy consumption of the CSIRS is optimized.

[0060] It can be understood that in addition to reducing the occupied frequency band of the CSIRS when the user demand decreases to avoid wasting time-frequency domain resources, the occupied frequency band of the CSIRS can also be expanded when the user demand increases to meet the user demand. The adaptive and dynamic adjustment of the occupied frequency band of the CSIRS can optimize the time-frequency domain resource management and utilization of the wireless base station without affecting the user's use perception.

[0061] According to the predetermined statistical period, the CSIRS information and the scheduling information are obtained, that is, based on the CSIRS information and the scheduling information every interval statistical period, the occupied frequency band of the CSIRS can be flexibly adjusted according to the change of the user calling the CSIRS, and the resource utilization rate of the wireless base station is improved while meeting the demand of the user.

[0062] In the CSIRS information, the time domain symbol reflects the occupied time domain resource, and the resource block (Resource Block, RB) sequence reflects the occupied frequency domain resource, as shown in Figure 6 , which is a schematic diagram of time-frequency domain resources, where the horizontal coordinate represents the time domain symbol, the vertical coordinate represents the subcarrier, and each square represents a resource block. When the CSIRS is configured, a sequence of allocated resource blocks will be selected, for example, in a certain case Figure 6 The resource blocks filled with slashes in the above figure are allocated to the CSIRS, and different time domain symbols may carry different numbers of resource blocks. In actual application, the user terminal requests the wireless base station to schedule the CSIRS according to the business demand, and the wireless base station allocates the corresponding time symbol and the corresponding subcarrier according to the user's request, that is, allocates the resource blocks occupied by the user terminal.

[0063] Adjusting the CSIRS occupied frequency band can modify the process of triggering the re-allocation of resource blocks by the CSIRS information, and specifically can modify the starting sequence number parameter and the occupied resource block quantity parameter of the CSIRS occupied resource blocks in the CSIRS information.

[0064] In the CSIRS occupied frequency band, the size of the frequency band can be represented by the number of resource blocks contained in the frequency band, or the size of the frequency band can be represented by the number of subcarriers contained in the frequency band, or it can also be directly represented by a specific frequency band.

[0065] The preset processing model can be a neural network model trained by historical CSIRS information, scheduling information and user change information to establish the relationship between the CSIRS information, the scheduling information and the user change information, and the processing model obtained after the training is an input of the CSIRS information and the scheduling information, and an output of the predicted user change information. The output predicted user change information includes the estimated user quantity and the estimated occupied resource block quantity corresponding to each time domain symbol.

[0066] Reference Figure 2 In some embodiments of the CSIRS frequency band adaptive adjustment method of the present application, the S400 comprises:

[0067] S410: calculating the resource utilization rate according to the user occupied resource block quantity;

[0068] S420: calculating the user scheduling success rate according to the scheduling successful user quantity and the estimated user quantity;

[0069] S430: calculating the resource scheduling success rate according to the user occupied resource block quantity and the estimated occupied resource block quantity;

[0070] S440: obtaining adjustment threshold information;

[0071] S450: adjusting the CSIRS occupied frequency band according to the adjustment threshold information, the resource utilization rate, the user scheduling success rate and the resource scheduling success rate.

[0072] By calculating the resource utilization, the utilization of the frequency band occupied by the CSIRS in the current working state can be known, reflecting the current user demand. By calculating the user scheduling success rate, the probability of successfully requesting scheduling of the CSIRS by the user can be known. By calculating the resource scheduling success rate, the probability of successfully scheduling resources can be known. The threshold information is used to determine whether the resource utilization, the user scheduling success rate and the resource scheduling success rate are out of the appropriate range, and then the CSIRS occupied frequency band is adjusted according to the comparison result. In this way, the resource utilization, the user scheduling success rate and the resource scheduling success rate can be numerically reflected to reflect the working condition of the CSIRS and the user demand, which is beneficial to accurately adjusting the CSIRS occupied frequency band.

[0073] In some embodiments of the CSIRS frequency band adaptive adjustment method, the resource utilization is calculated by the following formula:

[0074]

[0075] The user scheduling success rate is calculated by the following formula:

[0076]

[0077] The resource scheduling success rate is calculated by the following formula:

[0078]

[0079] Wherein, SR is the resource utilization; i is the serial number of the time domain symbol; n is the total number of time domain symbols; RB i is the number of resource blocks occupied by the user corresponding to the time domain symbol; Band is the current CSIRS occupied frequency band, expressed in the number of resource blocks; UR is the user scheduling success rate; U i is the number of successfully scheduled users corresponding to the time domain symbol; U pi is the estimated number of users corresponding to the time domain symbol; DR is the resource scheduling success rate; RB pi is the estimated number of occupied resource blocks corresponding to the time domain symbol.

[0080] The ratio of the number of resource blocks occupied by users corresponding to each time domain symbol to the number of resource blocks occupied by the current CSIRS is accumulated, and then divided by the number of time domain symbols to obtain a resource utilization ratio, reflecting the average resource utilization ratio of each time domain symbol. The ratio of the number of successfully scheduled users corresponding to each time domain symbol to the estimated number of users is accumulated, and then divided by the number of time domain symbols to obtain a user scheduling success rate, reflecting the proportion of the average number of successfully scheduled users to the estimated number of users in each time domain symbol. The ratio of the number of resource blocks occupied by users corresponding to each time domain symbol to the estimated number of occupied resource blocks is accumulated, and then divided by the number of time domain symbols to obtain a resource scheduling success rate, reflecting the proportion of the average number of successfully scheduled resource blocks to the estimated number of occupied resource blocks in each time domain symbol.

[0081] Reference Figure 3 In some embodiments of the CSIRS frequency band adaptive adjustment method of the application, the adjustment threshold information includes a first threshold, a second threshold, and a third threshold; and the S450 includes:

[0082] S451: When the resource utilization ratio is less than the first threshold, the user scheduling success rate is greater than the second threshold, and the resource scheduling success rate is greater than the third threshold, the CSIRS occupied frequency band is reduced;

[0083] S452: When the resource utilization ratio is less than the first threshold, the user scheduling success rate is less than or equal to the second threshold, and the resource scheduling success rate is less than or equal to the third threshold, the CSIRS occupied frequency band is expanded;

[0084] S453: When the resource utilization ratio is less than the first threshold, the user scheduling success rate is greater than the second threshold, and the resource scheduling success rate is less than or equal to the third threshold, the CSIRS occupied frequency band is modified.

[0085] When the resource utilization ratio is less than the first threshold, the user scheduling success rate is greater than the second threshold, and the resource scheduling success rate is greater than the third threshold, it means that it is in a low load condition, and the user scheduling CSIRS process is stable, and the CSIRS occupied frequency band can be reduced to reduce the occupation of time-frequency domain resources and release idle time-frequency domain resources.

[0086] When the resource utilization is less than the first threshold, the user scheduling success rate is less than or equal to the second threshold, and the resource scheduling success rate is less than or equal to the third threshold, it means that it is in a low load situation, but a large number of user scheduling CSIRS fails, which may be that users with high priority occupy available resources, and users with low priority in the quality of service queue frequently request to schedule the remaining resources but conflict to cause unsuccessful scheduling, therefore, the frequency band occupied by the CSIRS is expanded to enable users with low priority to successfully schedule resources, and the user scheduling success rate and the resource scheduling success rate are improved.

[0087] When the resource utilization is less than the first threshold, the user scheduling success rate is greater than the second threshold, and the resource scheduling success rate is less than or equal to the third threshold, it means that it is in a low load situation, although the user scheduling CSIRS success rate is high, the resource allocation success rate is low, which means that the user can successfully schedule CSIRS, but the user schedules a large frequency band, that is, a large number of resource blocks are required, which leads to resource scheduling failure, therefore, the frequency band occupied by the CSIRS is modified to meet the condition that a large number of resource blocks are required for single scheduling of users, and the resource scheduling success rate is improved.

[0088] The first threshold, the second threshold, and the third threshold are generally expressed as percentages, and the first threshold, the second threshold, and the third threshold can be different, in some embodiments of the present application, the first threshold, the second threshold, and the third threshold can be the same, that is, the same threshold is used to compare the resource utilization, the user scheduling success rate, and the resource scheduling success rate.

[0089] In some embodiments of the CSIRS frequency band adaptive adjustment method of the present application, the reduction of the CSIRS occupied frequency band is determined by the following formula:

[0090]

[0091] The expansion of the CSIRS occupied frequency band is determined by the following formula:

[0092]

[0093] The modification of the CSIRS occupied frequency band is determined by the following formula:

[0094]

[0095] Wherein, F is the CSIRS occupied frequency band; i is the serial number of the time domain symbol; n is the total number of time domain symbols; RB pi is the estimated occupied resource block number corresponding to the time domain symbol; SR is the resource utilization; Band is the current CSIRS occupied frequency band; the RB i is the user occupied resource block number corresponding to the time domain symbol.

[0096] When the CSIRS occupies the frequency band, the size of the CSIRS occupied frequency band is obtained by multiplying the sum of the estimated occupied resource block quantity corresponding to each time domain symbol by the resource utilization rate, based on the total resource block quantity that the future user will occupy and the resource utilization rate, which can guarantee to meet the demand of the estimated user scheduling CSIRS, and reduce the occupation of the time-frequency domain resource by the CSIRS.

[0097] When in the low load condition, but a large number of users fail to schedule the CSIRS, it may be that the user with high priority occupies the available resource, and the user with low priority in the quality of service queue frequently requests to schedule the remaining resource but conflicts occur to cause unsuccessful scheduling, therefore, the CSIRS occupied frequency band takes the larger one between the sum of the estimated occupied resource block quantity corresponding to each time domain symbol and the current CSIRS occupied frequency band. When the Band is large, it means that the current CSIRS occupied frequency band has fully met the resource block quantity demand of the user, and there is no need to expand the CSIRS occupied frequency band; and when the sum of the estimated occupied resource block quantity is large, it means that the total resource quantity cannot meet the user demand, which causes the user scheduling success rate and the resource scheduling success rate, therefore, the CSIRS occupied frequency band is expanded to the sum of the estimated occupied resource block quantity.

[0098] When the user can successfully schedule the CSIRS, but the user needs a large number of resource blocks, which causes the resource scheduling to fail, and the CSIRS occupied frequency band needs to be modified, based on the sum of the estimated occupied resource block quantity corresponding to each time domain symbol and the product of the resource utilization rate, the difference between the estimated occupied resource block quantity and the user occupied resource block quantity corresponding to each time domain symbol is added, in this way, on the basis of meeting the demand of the estimated user scheduling CSIRS, the difference between the estimated occupied resource block quantity and the user occupied resource block quantity is increased, which can meet the case that the user needs a large number of resource blocks in a single scheduling.

[0099] In some embodiments of the present application, when the calculated resource utilization rate is greater than a first threshold value and the CSIRS is a non-full-band setting, that is, the CSIRS occupied frequency band is less than an upper threshold value, the CSIRS occupied frequency band is increased. The increased CSIRS occupied frequency band can be determined by the product of the estimated occupied resource block quantity and the resource utilization rate.

[0100] Reference Figure 4 In some embodiments of the CSIRS frequency band adaptive adjustment method of the present application, the S440 comprises:

[0101] S441: inputting the CSIRS information and the scheduling information into a preset function model to obtain a traffic change curve;

[0102] S442: obtaining the adjustment threshold information according to the traffic change curve.

[0103] By processing based on the CSIRS information and the scheduling information through the function model, a predicted traffic change curve is obtained, the traffic change generated by the user in a future time is known, the demand of the user for the CSIRS is related to the traffic generated by the user, the two are positively correlated, and then based on the traffic change curve, adjustment threshold information is obtained, so that the adjustment threshold information is associated with the traffic generated by the user, and adjustment of the frequency band occupied by the CSIRS based on the adjustment threshold information is more in line with the demand change of the user, which is beneficial to make the judgment of adjusting the frequency band occupied by the CSIRS more accurate.

[0104] According to the traffic change curve, the adjustment threshold information can be obtained by multiplying the average value of the predicted traffic change by a preset coefficient.

[0105] In some embodiments of the application, the adjustment threshold information can also be obtained by inputting by the manager; the adjustment threshold information can also be obtained by a preset fixed threshold.

[0106] Reference Figure 5 In some embodiments of the CSIRS frequency band adaptive adjustment method of the application, further comprising:

[0107] S500: Record the CSIRS information, the scheduling information and the traffic information to form historical data information;

[0108] S600: After a preset number of statistical periods, the historical data information is used to iterate the function model.

[0109] Because the user types, work and rest habits and other factors in the service cell corresponding to different wireless base stations are different, for example, the service cell of the wireless base station is a residential cell, a commercial cell, an office cell and the like, the specific change relationship between the CSIRS scheduling and the traffic change of the user will also be different. Therefore, by recording the CSIRS information, the scheduling information and the traffic information during actual work to form historical data information, after a preset number of statistical periods, the historical data information is used to iteratively update the function model, which is beneficial to make the function model more suitable for the specific service cell of the work, and then after the iterative update, the CSIRS information and the scheduling information can be processed more accurately to obtain the predicted traffic change curve, and the adaptability of the function model to the specific service cell and the accuracy of the function model are improved.

[0110] The preset number of statistical periods can be set according to the actual application environment, and the total time of the preset number of statistical periods can be one week, which can cover the life habit period of the user.
