All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the examples of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
It should be understood that the term "and/or" as used herein is merely one type of associative relationship that describes an associated object, meaning that three types of relationships may exist, e.g., A and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
Before introducing the inner loop MCS determination method provided by the embodiment of the present invention, first, a simple introduction is made to the inner loop MCS determination method of the related art:
with the continuous development and progress of wireless communication technology, Long Term Evolution (LTE) technology using OFDM as a core technology is becoming mature and evolving towards 5G. The wireless channel has an important characteristic of strong time-varying property, and in order to maximize the throughput of the system and control the packet error rate of User Equipment (UE) so as to meet the communication requirements of different services, an effective link adaptation technology needs to be adopted. The link self-adaptive technology determines the MCS value through an inner ring mode and an outer ring mode, wherein the mode of determining the inner ring MCS value can select different Modulation Coding Schemes (MCS) according to the CQI value which changes in real time, the transmission rate is consistent with the channel characteristic through real-time adjustment, and the optimal information transmission rate is ensured. And in the actual adjustment process, the network side allocates an initial MCS and then gradually adjusts to the optimal MCS along with the new change of the network.
In the current implementation process of inner-loop MCS determination, each manufacturer usually adopts a policy of default configuration of an initial MCS value, or manually modifies the initial MCS value by background personnel. That is, when the initial MCS value is configured in the related art, it is difficult to configure a proper initial MCS value, so that it is easy to cause that the initial MCS value is configured too large or too small, which causes problems of increasing network delay, reducing network performance and reducing user perception when adjusting from the initial MCS value to the measured MSC value.
Taking a device of a manufacturer in the middle of a province as an example, as shown in table 1 below, under the same conditions, when the initial MCS values are configured as-3, 0, and 3, respectively, the download rates are significantly different, when the initial MCS value is configured as 3, the download rate is optimal, and at the same time, the MCS value ramp rate is fastest, which is a case that the initial MCS value configuration is low. This scenario also illustrates the rationality of the configuration of the initial MCS value, with a significant impact on user perception.
TABLE 1
Based on this, the technical problem to be solved by the embodiment of the present invention is: how to inquire out the initial MCS value of adaptation, in order to save the climbing time that the initial MCS value adjusts to inner loop MCS value, reduce the network delay, strengthen the network performance and strengthen the user's perception.

And 102, determining the grid where the terminal is located according to the current position information, and inquiring an initial MCS value corresponding to the grid from a pre-established first set.
And 103, judging whether the obtained measured MCS value is the same as the initial MCS value.
And step 104, if the obtained 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 located is determined according to the current position information, the initial MCS value corresponding to the grid is inquired from the pre-established first set, whether the acquired measured MCS value is the same as the initial MCS value is judged, if the acquired measured MCS value is judged to be the same as the initial MCS value, the initial MCS value is determined as the inner-ring MCS value, the adaptive initial MCS value can be inquired, the climbing time of adjusting the initial MCS value to the inner-ring MCS value is saved, and therefore, the network 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 another embodiment of the present invention, as shown in fig. 2, the method includes:
In the embodiment of the invention, each step is executed by a network side.
In the embodiment of the invention, the sampling position information can be obtained by obtaining the MR reported by the terminal within the preset time range. The sampling CQI value can be obtained by obtaining the CQI information reported by the terminal within the preset time range.
In the embodiment of the invention, the sampling position information comprises longitude and latitude. The dividing of the plurality of grids according to the plurality of sampling position information in step 202 may include generating a sampling position region according to the plurality of sampling position information, wherein the sampling position region includes the plurality of sampling position information, and the sampling position region is divided into the plurality of grids with reference to a preset length and a preset width.
In this embodiment of the present invention, the process of calculating the initial MCS value corresponding to each grid according to the sampled CQI value and the sampling location information in step 202 may specifically include:
step 2021, using the sampled CQI value and the sampling position information as a binary sampling point to obtain a plurality of binary sampling points.
In the embodiment of the present invention, according to the above steps, the MR reported by the terminal within the preset time range is obtained to obtain the sampling location information. The sampling CQI value can be obtained by obtaining the CQI information reported by the terminal within the preset time range. Because the CQI information is inconsistent with the period reported by the MR, the CQI value at the latest moment reported by the MR every time is calculated on the basis of the report of the MR. And binding the position information and the CQI value into binary sampling, and placing all binary sampling points into a set P. Specifically, assuming that in a certain time period, the MR reporting time interval is T, when a certain time T is reached, the terminal reports the MR, and acquires the sampled CQI value detected and reported by the terminal at the latest time within a { T-T/2, T + T/2} time range, and combines the sampled CQI value with the sampled position information in the MR reported by the terminal at the time T to form a binary sample point Pi ═ (Pix, Pic), where Pix represents the sampled position information and Pic represents the sampled CQI value, by the above-mentioned method, all binary sample points within a preset time range are calculated, and a set P ═ P (P1, P2.. Pn) is defined, where Pi represents the ith binary sample point among all the binary sample points, and each binary sample point includes the sampled position information and the sampled CQI value.
Step 2022, distributing the plurality of binary sample points to corresponding grids according to the sampling position information in the binary sample points.
In the embodiment of the present invention, according to the step 202, a plurality of grids can be geographically divided according to the sampling location information. The sampling position information comprises longitude and latitude, so that the grid corresponding to the sampling position information can be determined according to the longitude and latitude, namely the corresponding longitude and latitude range, the binary sampling points corresponding to the sampling position information can be distributed to the corresponding grid, and the plurality of binary sampling points can be distributed to the corresponding grid by executing the process, namely all the binary sampling points in a binary set P (P1, P2.. Pn) fall into the plurality of grids according to the sampling position information.
Step 2023, count the number of binary sample 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 different binary sampling points by counting the number of the binary sampling points in each grid.
Step 2024, if the number of the binary sample 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, the default MCS values set by different manufacturers are different, for example, the default MCS value is 0. That is, the default MCS value may be set according to requirements, which is not limited in the embodiment of the present invention.
Step 2024, if the number of the binary sample points in the grid is equal to 1, obtaining a sampled CQI value of the binary sample point, querying a first MCS value corresponding to the sampled CQI value from a pre-established mapping relation table, and determining the first MCS value as an initial MCS value.
In the embodiment of the present invention, the pre-established mapping table may be set according to requirements, for example, the pre-established mapping table is shown in table 2 below:
TABLE 2
| Initial MCS value | Sampling CQI values | Spectral efficiency |
| 0 | 2 | 0.2344 |
| 1 | 0.3057 | |
| 2 | 3 | 0.377 |
| 3 | 0.4693 | |

| 28 | 15 | 5.5547 |
As can be seen from table 2, when the number of the binary sample points in the grid is equal to 1, the sampled CQI values of the binary sample points are obtained, the first MCS value corresponding to the sampled CQI values is queried from the pre-established mapping relationship table, and the first MCS value is determined as the initial MCS value. For example, when the sampled CQI value of the obtained binary sample 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 to be the initial MCS value, that is, the initial MCS value is equal to 2. Further, the spectrum efficiency in table 2 above is used to indicate the efficiency of using the initial MCS value, that is, when the initial MCS value is larger, it indicates that the higher the spectrum efficiency is, the better the rate sensing is.
Step 2025, if the number of the binary sample points in the grid is greater than 1, calculating the average value of the sampled CQI values of all the binary sample points in the grid, querying a second MCS value corresponding to the average value of the CQI values from a 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 sampling points in the grid is more than 1, the average value of the sampled CQI values in all the binary sampling points in the grid is calculated, and the second MCS value corresponding to the average value of the CQI values is determined as the initial MCS value according to the CQI-MCS mapping relation table shown in the table 2.
It should be noted that, when calculating the average value of the sampled CQI values, the average result needs to be rounded down. For example, when the mean of the sampled CQI values for a binary sample is equal to 2.1, then the mean of the sampled CQI values is equal to 2. For example, when the mean of the sampled CQI values for a binary sample is equal to 2.9, the mean of the sampled CQI values is equal to 2. That is, the average of the sampled CQI values is calculated, and the result of the averaging is rounded down, i.e., the integer portion is taken as the average of the sampled CQI values.
In the embodiment of the present invention, the initial MCS value corresponding to each trellis can be calculated in step 202, and step 203 is executed to generate the first set, specifically, the first set Q is (Q1, Q2.. Qm), where Qi represents the initial MCS value corresponding to the ith trellis, from the plurality of trellis and the initial MCS value corresponding to each trellis.
In the embodiment of the present invention, after step 203, the method further includes: a first set is stored, Q, (Q1, Q2.. Qm), where Qi represents the initial MCS value corresponding to the ith trellis.
And step 204, acquiring 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.
In the embodiment of the invention, the current position information comprises longitude and latitude, a longitude and latitude unit where the longitude and latitude is located, namely a 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 comprises the initial MCS value corresponding to each grid, the initial MCS value corresponding to the grid can be inquired from the pre-established first set.
Specifically, in practical application, when the terminal moves into a certain grid, the terminal reports the current position information through the MR, the current position information is matched with the first set of the network side, and the network side uses the initial MCS value corresponding to the grid where the terminal is located in the first set as the initial MCS value of the terminal.
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 of the channel transmission, and the process is ended; if the obtained measured MCS value is determined to be different from the initial MCS value, which indicates that the network side does not obtain the optimal modulation and coding format for channel transmission, step 208 needs to be executed to obtain the optimal modulation and coding format for channel transmission.
In the embodiment of the present invention, before step 206, the method further includes: after entering the adaptive modulation and coding process, acquiring a current CQI value reported by a terminal; and determining the MCS value to be measured according to the current CQI value.
In the embodiment of the invention, when the network side and the terminal enter the adaptive modulation coding process, 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 determines the initial MCS value as the inner loop MCS value.
In the embodiment of the invention, because the network side already obtains the modulation coding format with the best channel transmission, the initial MCS value is determined as the inner loop MCS value.
In the embodiment of the present invention, step 208 may specifically include: and adjusting the initial MCS value to be the same as the obtained measured MCS value, and determining the measured MSC value as an inner ring 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 obtained measured MCS value may include: and according to preset defined time, adding a set step length to the initial MCS value, judging whether the MCS value after the set step length is added is equal to the obtained measured MCS value, and if the MCS value after the set step length is added is judged to be smaller than the obtained measured MCS value, continuing to add the set step length to the MCS value until the MCS value is equal to the obtained measured MCS value. That is, until the initial MCS value is adjusted to the optimal MCS value, the modulation and coding format optimal for channel transmission can be obtained. In the embodiment of the invention, the adaptive initial MCS value is inquired and adjusted to the optimal MCS value from the initial MCS value, compared with the adjustment to the optimal MCS value from the self-set default MCS value, the ramp time for adjusting the initial MCS value to the inner ring MCS value is saved, and the consistency of the transmission rate and the channel characteristic can be realized more quickly.
