Detailed Description
Embodiments of the present invention will be described below with reference to the accompanying drawings.
In the related technology, the interference value of the adjacent cell to the serving cell is calculated by acquiring the MR, so that the difference of the important relationship between the level intensity coverage and the number of sampling points in different areas in the serving cell cannot be represented objectively and accurately, and further, the optimal calculation of a cell frequency point scheme, a cell scrambling scheme, a neighboring cell scheme and a coverage scheme cannot be performed on the basis of a wireless network interference matrix generated by an existing algorithm and effectively aiming at the actual wireless network environment.
Therefore, the embodiments of the present invention provide a method and an apparatus for generating an inter-cell interference value, which perform weighted averaging on preliminarily obtained interference values between neighboring cells and a serving cell, modify an interference weight between the neighboring cells and the serving cell, and modify the interference value after the weighted averaging by the modified interference weight, so that the finally obtained interference value between the neighboring cells and the serving cell more objectively and accurately represents differences in important relationships between level strengths and coverage of different areas in the serving cell and the number of sampling points, thereby facilitating implementation of a related scheme by subsequent interference values.
In the embodiment provided by the present invention, first, a method for generating an inter-cell interference value is provided, where the method is applied to a base station side corresponding to a terminal, as shown in fig. 1, the method may include the following steps:
in step S110, the measurement report transmitted by the terminal is received.
The terminal may obtain measurement information of the target cell and may also obtain measurement information of a neighboring cell of the target cell. In the embodiment of the invention, the target cell can comprise a service cell and a quasi-service cell, wherein the quasi-service cell is a standby service cell of the terminal, the signal intensity and the like of the standby service cell are only secondary to the service cell, once the service cell can not provide normal communication service for the terminal, the terminal can be switched to the quasi-service cell, and the quasi-service cell is converted into the service cell of the terminal.
Therefore, the MR sent by the terminal obtained by the base station in the embodiment of the present invention may include measurement information of a target cell and measurement information of neighboring cells of the target cell, where the target cell includes a serving cell and a quasi-serving cell.
In step S120, a first interference value between the neighboring cell and the target cell is obtained.
Wherein the first interference value is calculated from the measurement information in the MR.
In the embodiment of the present invention, a serving cell and an adjacent cell are taken as an example for description, and interference between the serving cell and the adjacent cell measured by a terminal is taken as a coherent cell pair.
For example, for the LTE system, considering that the number of neighbor cells measured by the MR is relatively limited, in the measurement report obtained by the base station, for each MR, it is assumed that the received signal level of the serving cell measured by the terminal is C and the received signal level of the neighbor cell is I, and if the I/C of the neighbor cell is greater than-12 dB, it indicates that the interference between the neighbor cell and the serving cell is sufficient to affect the normal communication of the terminal, so the interference between all neighbor cells and the serving cell, whose I/C is greater than-12 dB, needs to be considered. If the I/C is not more than-12 dB, the influence of the adjacent cell on the service cell is not great, or the service cell can be switched to a quasi-service cell at the moment, and the interference of the adjacent cell with the I/C not more than-12 dB on the service cell does not need to be considered.
It should be noted that, in the embodiment of the present invention, the interference between the serving cell and the neighboring cell may be calculated by the following manner, that is:
where FER (C/I) represents a first interference value between the neighboring cell and the target cell, C is a received signal level of the serving cell, and I is a received signal level of the neighboring cell.
In step S130, a second interference value between the neighboring cell and the target cell is obtained.
Wherein the second interference value is a weighted average of the first interference value.
Because the interference value between the adjacent cell and the serving cell calculated by the above method is not considered comprehensively, the interference between the adjacent cell and the serving cell cannot be represented objectively and accurately by the first interference value, and therefore, the first interference value needs to be weighted and averaged, and the interference between the adjacent cell and the serving cell is represented by the second interference value obtained after weighted averaging, so that the obtained result is more objective and accurate.
Therefore, in order to detail how the first interference value is weighted and averaged in the embodiment of the present invention, in a further embodiment provided by the present invention, the measurement report includes a plurality of measurement information of the neighboring cells, and the measurement information includes a first received signal level of the target cell and a second received signal level of the neighboring cell, as shown in fig. 2, step S130 may further include the following steps:
in step S131, a first target number of second received signal levels is acquired.
Wherein the first target number is a number of second received signal levels in the neighboring cell for which a ratio of the second received signal level to the first received signal level is greater than a threshold. In addition, in the embodiment provided by the present invention, the number satisfying that the I/C between the neighboring cell and the serving cell is greater than-12 dB may also be taken as the first target number in the above manner.
In step S132, a first interference weight of the neighboring cell is acquired.
Wherein the first interference weight is determined by the second received signal level. Specifically, the manner of obtaining the first interference weight may include:
and S1, obtaining a value range to which the second received signal level belongs, wherein each received signal level in the value range corresponds to an interference weight.
S2, the interference weight corresponding to the second received signal level in the value range is used as the first interference weight.
For example, in the embodiments provided in the present invention, different second received signal levels respectively correspond to a first interference weight, that is, there is a certain corresponding relationship between the second levels and the first interference weights. Specifically, the information may be obtained by looking up a table or obtaining a preset function. For example, when obtaining the first interference weight, the embodiment of the present invention divides the second received signal level into two intervals in consideration of the difference of the interference degree of the different second received signal levels to the serving cell: -120, -100 (unit dB) and more than-100 dB, which correspond to two different curve functions, respectively, and by determining the value of the second received signal level, the corresponding interference weight, i.e. the first interference weight, can be obtained in the corresponding interval.
In step S133, the first interference value is weighted and averaged by the first target number and the first interference weight, so as to obtain a second interference value.
After the parameters are obtained, the embodiment of the invention can perform weighted average calculation on the first interference value to obtain the second interference value. Specifically, the first interference values and the first interference weight products corresponding to the first interference values may be summed, and the sum is divided by the first target number to obtain a second interference value obtained by weighted averaging the first interference weights.
In order to further objectively and accurately calculate the interference value between the neighboring cell and the serving cell, in a further embodiment provided by the present invention, in combination with the above embodiment, as shown in fig. 3, the method may further include the following steps:
in step S140, a second interference weight of the neighboring cell is obtained, the second interference weight being determined by the second received signal level.
And the second interference weight and the first interference weight are obtained in different modes.
The first interference weight in the above embodiment considers the difference of the values of the second received signal levels, and may be determined by using corresponding functions in different intervals, whereas the second interference weight provided in the embodiment of the present invention determines the second interference weight and the second received signal level by using one function from the perspective of the whole neighboring cell, that is, does not distinguish the intervals. That is, different second received signal levels respectively correspond to a second interference weight, and a determined correspondence exists between the second received signal levels and the second interference weights, or the second interference weights can be obtained by looking up a table through the second received signal levels.
In step S150, a second target number corresponding to the second received signal level is obtained.
Wherein the second target number is the number of second received signal levels in all neighboring cells for which the ratio of the second received signal level to the first received signal level is greater than a threshold.
In step S160, the second interference weight is corrected according to the first target number and the second target number, so as to obtain a third interference weight.
For example, the embodiment of the present invention may correct the second interference weight by dividing the sum of the second interference weights corresponding to the second received signal levels in the target neighboring cells satisfying the condition by the sum of the second interference weights corresponding to the second received signal levels satisfying the condition in all the cells, and using the corrected interference weight as the third interference weight. Wherein the condition is that a ratio of the second received signal level to the first received signal level is greater than a threshold.
In step S170, a third interference value is determined by the second interference value and the third interference weight, and the third interference value is used as an interference value between the neighboring cell and the target cell.
The product of the second interference value and the third interference weight is the third interference weight.
According to the inter-cell interference value generation method provided by the embodiment of the invention, the calculated first interference value is weighted and averaged to obtain the second interference value, and the second interference value can be used as the interference value between the adjacent cell and the service cell, so that the second interference value is more accurate than the first interference value. In addition, in order to obtain a more accurate and objective interference value between the serving cell and the interfering cell, the embodiment of the present invention corrects the second interference value by the above method, uses the obtained third interference value as an interference value between the serving cell and the adjacent cell, and further can calculate the interference values between all the adjacent cells and the serving cell (or the quasi serving cell) by this method to obtain an interference matrix, which is beneficial to subsequent applications such as a cell frequency point scheme and a cell scrambling scheme by the interference matrix.
