In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.
Before introducing an inner loop MCS determination method provided by the embodiment of the present invention, a related art inner loop MCS determination method is first briefly described:
with the continuous development and progress of wireless communication technology, long term evolution (Long Term Evolution, abbreviated as LTE) with OFDM as a core technology is mature and evolves toward 5G. The important characteristic of the wireless channel is that the wireless channel has strong time variability, and in order to maximally improve the throughput of the system, the packet error rate of User Equipment (UE) is controlled at the same time so as to meet the communication requirements of different services, and an effective link self-adaptive technology is required to be adopted. The link self-adaptive technology determines the MCS value through an inner loop and an outer loop, wherein the manner of determining the MCS value of the inner loop can select different Modulation Coding Schemes (MCS) according to the CQI value which changes in real time, and the transmission rate is consistent with the channel characteristic through real-time adjustment, so that the optimal information transmission rate is ensured. In the actual adjustment process, the network side distributes the initial MCS, and then gradually adjusts to the optimal MCS along with the new change of the network.
In the current implementation process of determining the inner loop MCS, each manufacturer generally adopts a strategy of default configuration of an initial MCS value, or manually modifies the initial MCS value by a background personnel. That is, when configuring the initial MCS value in the related art, it is difficult to configure a proper initial MCS value, which easily results in that the initial MCS value is configured too much or too little, which results in problems of increasing network delay, degrading network performance, and degrading user perception when adjusting from the initial MCS value to the measured MSC value.
Taking some province manufacturer equipment as an example, as shown in the following table 1, under the same condition, when the initial MCS value is configured as-3, 0 and 3 respectively, the downloading rate has obvious difference, when the initial MCS value is configured as 3, the downloading rate is optimal, and meanwhile, the climbing rate of the MCS value is also the fastest, and the scene is a case that the initial MCS value is configured to be lower. This scenario also illustrates the rationality of the configuration of the initial MCS values, with a significant impact on user perception.

Based on the above, the technical problems to be solved by the embodiment of the invention are as follows: how to query the adaptive initial MCS value, so as to save the climbing time for adjusting the initial MCS value to the inner loop MCS value, reduce the network delay, enhance the network performance and enhance the user perception.

and 101, acquiring current position information reported by a terminal.
Step 102, determining a grid where the terminal is located according to the current position information, and inquiring an initial MCS value corresponding to the grid from a first set established in advance.
Step 103, judging whether the obtained measured MCS value is the same as the initial MCS value.
And 104, if the acquired measured MCS value is judged to be the same as the initial MCS value, determining the initial MCS value as an inner ring MCS value.
In the technical scheme provided by the embodiment of the invention, the current position information reported by the terminal is acquired, the grid where the terminal is positioned is determined according to the current position information, the initial MCS value corresponding to the grid is inquired from the first set which is established in advance, whether the acquired measured MCS value is identical to the initial MCS value is judged, if the acquired measured MCS value is judged to be identical to the initial MCS value, the initial MCS value is determined to be the inner ring MCS value, the adaptive initial MCS value can be inquired, the climbing time for adjusting the initial MCS value to the inner ring MCS value is saved, and therefore, the network time delay is reduced, the network performance is enhanced, and the user perception is enhanced.
Fig. 2 is a flowchart of a method for determining an inner loop MCS according to still another embodiment of the present invention, as shown in fig. 2, the method includes:
step 201, acquiring a sampling CQI value and sampling position information reported by a terminal in a preset time range.
In the embodiment of the invention, each step is executed by the network side.
In the embodiment of the invention, the sampling position information can be obtained by obtaining the MR reported by the terminal in the preset time range. The sample CQI value may be obtained by obtaining CQI information reported by the terminal within a preset time frame.
Step 202, dividing a plurality of grids according to the plurality of sampling position information, and calculating an initial MCS value corresponding to each grid according to the sampling CQI value and the sampling position information.
In the embodiment of the invention, the sampling position information comprises longitude and latitude. The dividing the plurality of grids according to the plurality of sampling position information in step 202 may include generating a sampling position area according to the plurality of sampling position information, wherein the sampling position area includes the plurality of sampling position information, and dividing the sampling position area to divide into the plurality of grids based on the preset length and the preset width.
In the embodiment of the present invention, in step 202, the process of calculating the initial MCS value corresponding to each grid according to the sampling CQI value and the sampling position information may specifically include:
step 2021, taking the sampled CQI value and the sampling position information as the binary set sampling points to obtain a plurality of binary set sampling points.
According to the embodiment of the invention, according to the steps, the sampling position information can be obtained by obtaining the MR reported by the terminal in the preset time range. The sample CQI value may be obtained by obtaining CQI information reported by the terminal within a preset time frame. And calculating the CQI value at the latest moment of each MR report based on the MR report because the CQI information is inconsistent with the period of the MR report. And binding the position information and the CQI value into the binary group sampling, and placing all binary group sampling points into the set P. Specifically, assuming that the MR reporting time interval is T in a certain time period, when the MR reporting time interval is a certain time T, the terminal reports the MR, acquires a sampling CQI value which is detected and reported by the terminal at the time T in a { T-T/2, t+t/2} time range, and composes a binary group sampling point pi= (Pix, pic) by adopting the CQI value and sampling position information in the MR which is reported by the terminal at the time T, wherein Pix is represented as sampling position information, pic is represented as sampling CQI value, by calculating all binary group sampling points in a preset time range in the above manner, and defining a set p= (P1, P2.) Pn, wherein Pi is represented as an ith binary group sampling point in all binary group sampling points, and each binary group sampling point contains sampling position information and sampling CQI value.
Step 2022, allocating the plurality of binary sampling points into corresponding grids according to the sampling position information in the binary sampling points.
In the embodiment of the present invention, according to the step 202, a plurality of grids can be divided geographically according to the sampling position information. The sampling position information includes longitude and latitude, so that a grid corresponding to the sampling position information, namely, a corresponding longitude and latitude range can be determined according to the longitude and latitude, so that the binary group sampling points corresponding to the sampling position information can be distributed into the corresponding grids, and by executing the flow, a plurality of binary group sampling points can be distributed into the corresponding grids, namely, all binary group sampling points in a binary group set p= (P1, P2..pn) fall into the plurality of grids according to the sampling position information.
Step 2023, counting the number of binary set sampling points in each grid.
In the embodiment of the invention, the initial MCS value corresponding to each grid is determined according to the number of the different binary group sampling points by counting the number of the binary group sampling points in each grid.
Step 2024, if the number of binary set sampling points in the grid is equal to 0, determining the obtained default MCS value as the initial MCS value corresponding to the grid.
In the embodiment of the present invention, default MCS values set by different manufacturers are different, for example, default MCS value=0. That is, the default MCS value may be set according to the requirement, which is not limited in the embodiment of the present invention.
Step 2024, if the number of the binary group sampling points in the grid is equal to 1, acquiring the sampling CQI value of the binary group sampling points, inquiring the first MCS value corresponding to the sampling CQI value from the pre-established mapping relation table, and determining the first MCS value as the initial MCS value.
In the embodiment of the present invention, the pre-established mapping relation table may be set according to requirements, for example, the pre-established mapping relation table is shown in the following table 2:
TABLE 2
| Initial MCS value | Sampling CQI values | Spectral efficiency |
| 0 | 2 | 0.2344 |
| 1 | 0.3057 | |
| 2 | 3 | 0.377 |
| 3 | 0.4693 | |
| 4 | 4 | 0.6016 |
| 5 | 0.7393 | |
| 6 | 5 | 0.877 |
| 7 | 1.0264 | |
| 8 | 6 | 1.1756 |
| 9 | 1.3262 | |
| 10 | 1.3262 | |
| 11 | 7 | 1.4766 |
| 12 | 1.6954 | |
| 13 | 8 | 1.9141 |
| 14 | 2.1602 | |
| 15 | 9 | 2.4063 |
| 16 | 2.5684 | |
| 17 | 2.5684 | |
| 18 | 10 | 2.7305 |
| 19 | 3.0264 | |

| 26 | 14 | 5.1152 |
| 27 | 5.335 | |
| 28 | 15 | 5.5547 |
As can be seen from table 2, when the number of the binary group sampling points in the grid is equal to 1, the sampling CQI values of the binary group sampling points are obtained, the first MCS value corresponding to the sampling CQI value is queried from the pre-established mapping relation table, and the first MCS value is determined as the initial MCS value. For example, when the sampled CQI value of the obtained binary group sampling point is equal to 3, the first MCS value corresponding to the sampled CQI value is equal to 2, and the first MCS value is determined as the initial MCS value, that is, the initial MCS value is equal to 2. Furthermore, the spectral efficiency in table 2 above is used to indicate the efficiency of using the initial MCS value, that is, the higher the initial MCS value, the better the rate perception.
Step 2025, if the number of the binary group sampling points in the grid is greater than 1, calculating the average value of the sampling CQI values of all the binary group sampling points in the grid, and inquiring a second MCS value corresponding to the average value of the CQI values from the pre-established mapping relation table, and determining the second MCS value as the initial MCS value.
In the embodiment of the invention, when the number of the binary group sampling points in the grid is greater than 1, the average value of the sampling CQI values in all the binary group sampling points in the grid is calculated, and according to the CQI-MCS mapping relation table shown in the table 2, a second MCS value corresponding to the average value of the CQI values is determined as the initial MCS value.
When calculating the average value of the sampled CQI values, the average value result needs to be rounded down. For example, when the average of the binary set of sample point CQI values is equal to 2.1, the average of the sample CQI values is equal to 2. For example, when the average of the binary set of sample point CQI values is equal to 2.9, the average of the sample CQI values is equal to 2. That is, the average value of the sampled CQI values is calculated, and the average result is rounded down, i.e., an integer part is taken as the average value of the sampled CQI values.
Step 203, generating a first set according to the multiple grids and the initial MCS value corresponding to each grid.
In the embodiment of the present invention, through the above step 202, an initial MCS value corresponding to each grid can be calculated, and through executing step 203, a first set is generated according to a plurality of grids and the initial MCS value corresponding to each grid, specifically, the first set q= (Q1, q2..qm), where Qi represents the initial MCS value corresponding to the i-th grid.
In an embodiment of the present invention, after step 203, the method further includes: the first set, q= (Q1, Q2..qm), is stored, where Qi represents the initial MCS value corresponding to the i-th grid.
Step 204, obtaining the current position information reported by the terminal.
In the embodiment of the invention, when the terminal moves, the current position information reported by the terminal can be acquired.
Step 205, determining the grid where the terminal is located according to the current position information, and inquiring the initial MCS value corresponding to the grid from the first set established in advance.
In the embodiment of the invention, the current position information comprises longitude and latitude, and the longitude and latitude unit where the longitude and latitude is located, namely the grid where the longitude and latitude is located, can be determined according to the longitude and latitude, and because the first set is determined in the steps and the first set comprises the initial MCS value corresponding to each grid, the initial MCS value corresponding to the grid can be queried from the first set which is established in advance.
Specifically, in practical application, when the terminal moves into a certain grid, the terminal reports current position information through MR, the current position information is matched with a first set of a network side, and the network side uses an initial MCS value corresponding to the grid where the terminal is located in the first set as an initial MCS value of the terminal.
Step 206, judging whether the obtained measured MCS value is the same as the initial MCS value, if yes, executing step 207; if not, go to step 208.
In the embodiment of the invention, if the obtained measured MCS value is judged to be the same as the initial MCS value, the network side is indicated to obtain the optimal modulation coding format for channel transmission, and the flow is ended; if the obtained measured MCS value is not the same as the initial MCS value, it indicates that the network side does not obtain the modulation coding format with the optimal channel transmission, step 208 needs to be executed to obtain the modulation coding format with the optimal channel transmission.
In an embodiment of the present invention, before step 206, the method further includes: when the adaptive modulation and coding flow is entered, the current CQI value reported by the terminal is obtained; and determining a measured MCS value according to the current CQI value.
In the embodiment of the invention, when the network side and the terminal enter the self-adaptive modulation and coding flow, the terminal reports the current CQI value, and the measured MCS value is obtained after the processing of the network side, wherein the measured MCS value can be understood as the optimal MCS value.
Step 207, determining the initial MCS value as an inner loop MCS value.
In the embodiment of the invention, the initial MCS value is determined as the inner loop MCS value because the network side has obtained the optimal modulation coding format for channel transmission.
Step 208, the initial MCS value is adjusted, and the adjusted initial MCS value is determined as the inner loop MCS value.
In an embodiment of the present invention, step 208 may specifically include: the initial MCS value is adjusted to be the same as the acquired measured MCS value and the measured MSC value is determined as the inner loop MSC value.
In the embodiment of the invention, if the measured MSC value is not equal to the initial MCS value, the network side can adjust the initial MCS value to the measured MSC value according to the step length and the time which are defined in advance. Specifically, the process of the network side adjusting the initial MCS value to be the same as the acquired measured MCS value may include: and adding a set step length to the initial MCS value according to a preset definition time, judging whether the MCS value after adding the set step length is equal to the acquired measurement MCS value, and if the MCS value after adding the set step length is smaller than the acquired measurement MCS value, continuing adding the set step length to the MCS value until the MCS value is equal to the acquired measurement MCS value.
