Description

ABS configuration device, configuration device and method

The present invention relates to the field of communications technologies, and in particular, to an ABS configuration apparatus, a configuration apparatus, and a method.

Background technique

Heterogeneous network is a network deployment method defined by 3GPP (3rd Generation Partnership Project). In heterogeneous networks, there are macro cells and micro cells, and micro cells include pico base stations (pico) cells and homes. Base station ( femto ) cell. The macro cell provides wide-area continuous signal coverage, and the micro cell provides local small-range signal coverage. The micro cell often enhances the local coverage of the macro cell's signal coverage area based on the macro cell wide-area continuous signal coverage, so the macro cell and the micro cell The signal coverage of the area is overlapping, which causes signal interference between the macro cell and the micro cell, thereby reducing the overall performance of the network.

In order to improve the overall performance of the network, in the prior art, 3GPP defines an ABS (Almost Blank Sub-frame) technology, and the ABS technology reduces interference by causing the interference source cell to stop transmitting data in some subframes. The interference strength of the source cell to the interfered cell within the time period in which the subframe in which the data is to be transmitted is stopped.

However, in the prior art, the ABS technology only considers two cases: one is that a single macro cell interferes with a single pico cell, and the other is that multiple macro cells interfere with a single pico cell. In an actual network, a cell is often both an interference source cell and an interfered cell, and multiple cells interfere with multiple cells. This complex mutual interference is common, such as: cell 1 interfering cell 2, cell 2 interference Cell 3, cell 3 interferes with cell 1.

detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The technical solution provided by the embodiment of the present invention can be applied to a heterogeneous network, and the heterogeneous network includes at least two cells. In a heterogeneous network, multiple different types of cells may coexist, and each cell includes multiple users, such as a macro cell and a micro cell. The micro cell may be a pico base station (pico) cell, a femto cell, or the like. The interference relationship between multiple cells in a heterogeneous network depends on factors such as the relative location of the cell, the type of base station of the cell, and the distribution of cell users. For example, the signal coverage of the macro cell often overlaps with the signal coverage of the nearby micro cell. Therefore, the macro cell and the micro cell cause signal interference with each other, and the macro cell interferes with the pico base station cell, and the home base station cell interferes with the macro cell. There are three basic interference relationships in a heterogeneous network: a single cell interferes with multiple cells, chain interference between cells, and multiple cells interfere with a single cell. For example, as shown in FIG. 1, the FBS (Home Base Station) cell interferes with MBS (macro base station) cell 1, FBS (home base station) cell interferes with MBS (macro base station) cell 2, in which case a single cell interferes with multiple cells; FBS cell trunk 4 especially MBS cell 1, MBS cell 1 dry 4 especially PBS (: base station) cell, this case is chain interference between three cells; MBS cell 1 interferes with PBS cell, MBS cell 2 interferes with PBS cell, This situation is where multiple cells interfere with a single cell. Through the combination of these three basic interference relationships, complex interference relationships between multiple cells in the actual network can be formed. The present invention sets the ABS configuration of the interference source cell for each cluster according to the interference relationship between the interference source cell and the interfered cell, thereby implementing complex interference relationships between multiple cells. ABS configuration.

In this solution, the configuration device needs to obtain the cell information of each cell in the heterogeneous network and the user information of the user in the cell. In a specific implementation process, the cell information and the user information may be measured by the terminal in an active state. The terminal may be a device that can be used for communication, such as a mobile phone or a computer, and the terminal may perform RSRP (Reference Signal Receiving Power) measurement. CQI (Channel Quality Indicator) measurement, etc., through RSRP measurement, CQI measurement, etc., the terminal can acquire the number of resource blocks in the cell, the cell ID, the neighbor cell ID of the cell, the power of the user, and the cell is interfered by other cells. The information such as the interference strength is reported and stored in the configuration device on the network side. The measurement result reported by the device terminal is configured.

The embodiment of the present invention provides a method for configuring an ABS, which is applied to a heterogeneous network. The heterogeneous network includes at least two cells. As shown in FIG. 7, the method includes:

701. Acquire cell information of a cell and user information of a user in the cell. The cell information includes at least a total number of resource blocks (RBs) and a number of resource blocks used by the cell, and the user information includes at least a user's signal dry noise. The user information may also include the interference strength of the cell that interferes with the user, the cell identity of the cell that interferes with the user, and the like, and the number of resource blocks that the user occupies on average.

It should be noted that the cell may be divided into multiple regions, and each region is referred to as a geographic pixel. The user information of the user in the cell may also be the geographic pixel information of the geographic pixel in the cell, and the geographic pixel information includes at least the signal to interference and noise ratio of the geographic pixel and the number of resource blocks occupied by the geographic pixel.

702. Determine, by using the cell information and the user information, an interfered cell and an interference source cell corresponding to the interfered cell.

The cell load can be obtained by using the cell information; the user information can be used to determine the interfered user that is interfered by the cell; and thus, according to the cell load and related information of the interfered user, such as the number of resource blocks occupied by the interfered user, An interfering cell and an interference source cell corresponding to the interfered cell.

The number of the interference source cells corresponding to one interfered cell is not limited, and may be one or multiple. It should be noted that a cell may be both an interfered cell and an interferer cell.

703. Perform clustering on the heterogeneous network by using an interference relationship between the interference source cell and the interfered cell.

Among them, cells having an interference relationship are divided into the same cluster. The interference relationship between cells in the same cluster can form a connected mesh relationship. For example, as shown in FIG. 7a, cells 1-7 belong to the same cluster, and arrows point to indicate interference, that is, cell 1 interferes with cell 5, and cell 2 interferes. Cell 1 , as can be seen from FIG. 7a , a cell may be a simple interference source cell, such as cell 3; a cell may also be a simple interfered cell, such as cell 5; a cell may also be an interference source cell. At the same time, it is also an interfered cell, such as cell 7; according to the interference relationship between cells 1-7, it can be determined that cells 1-7 are divided into one cluster; wherein, the interference strength between cells 1-7 is greater than the interference intensity value.

In this solution, there will be interference relationships and the interference strength between cells is greater than or equal to dry. The cells with the high-interference strength are divided into the same cluster, and a cell can be determined first, and the cell is added as the trunk of the cell, and the cell is used as the interfered cell. The interfering source cell also joins the cluster in which the cell is located. At the same time, the cell with the interference relationship of the interfered cell corresponding to the cell as the interference source cell is also added to the cluster where the cell is located, and the cell corresponding to the cell is the interference corresponding to the interfered cell. A cell in which the source cell has an interference relationship also joins the cluster in which the cell is located, and so on, and all cells in a cluster can be determined. An interference relationship exists between any one cell in the same cluster and other at least one cell in the same cluster, and there is no interference relationship between cells in different clusters; or any one cell in the same cluster and other at least one cell in the same cluster There is an interference relationship, and the interference strength between cells in different clusters does not exceed the preset interference intensity threshold. As shown in FIG. 7b, the cells 1-10 are divided into two clusters, the cells 1-7 are a cluster, and the cells 8-10 are another cluster, wherein any of the cells 1-7 and the cells 8-10 Any of the cells has no interference relationship or the interference strength does not exceed the interference intensity threshold.

In a specific implementation process, the cells may be clustered according to the connectivity of the interference relationship between cells, and a pseudo code for clustering is given below:

Function name: function v i c t im_ check

Input: DI (interference source cell), current cluster (CLUSTER), interference relationship, community attribute (DI or victim)

Output: Cell collection of the current cluster

If there is unv i s i t ed victim of DI

Get a victim cell victim_c of D I;

If victim-c not belongs to CLUSTER

Add it to CLUSTER;

If victim-c is a D I

Call victim-check with victim_c and CLUSTER;

End

End End

Return

The pseudo code indicates that any current DI (Dominant interferer) is obtained, traverses the neighboring cell around the DI, and the cell interfered by the DI is added to the current cluster (CLUSTER), if The cell vict im-c of the DI interference is also a DI, and the cell that is interfered by the vict im_c is also found to be forced into the current CLUSTER; the function victim-check is continuously called to recursive function. Divided into cells in a cluster. The cell attribute of a cell may be a victim or an interference source cell, or may be both an interfered cell and an interference source cell.

704. Perform an almost full blank subframe ABS configuration on the interference source cell in a cluster for an interference relationship between the interference source cell and the interfered cell in a cluster of cells.

The clustering of the cells implements the simplification of the complex interference relationship between the cells, and performs ABS (Almost Blank Sub) on the interference source cells for the interference relationship between the interference source cell and the interfered cell in a cluster of cells. -frame, almost full blank subframe) configuration. When performing ABS configuration on the interference source cell, the signal quality and network performance of the interfered cell should be considered on the one hand, and the signal quality and network performance requirements of the interference source cell should also be considered on the other hand. When there is only one interference source cell in a cluster of cells, only the interference source cell needs to be set; when there are at least two interference source cells in a cluster of cells, all the interference source cells in the clustered cell need to be combined. Perform ABS configuration on all interferer cells in this cluster of cells.

Optionally, when the ABS is configured for the interference source cell, the target of the KPI (Key Performance Indicator) is obtained, and the time of the almost blank subframe is obtained, so that the ABS is configured for the interference source cell. KPIs can be performance indicators such as total throughput and fairness.

A method for configuring an ABS according to an embodiment of the present invention can be configured according to each cell The cell information and the user information of the user in the cell determine the interfered cell and the corresponding interferer cell, and according to the interference relationship between the interfered cell and the interferer cell, cluster the interference source cell and the interfered cell for each The interference source cell in the cluster cell performs ABS configuration. Compared with the prior art that only considers a single cell to interfere with a single cell and multiple cells interfere with a single cell, the solution determines the interfered cell and the interferer cell according to the cell information and the user information, and according to The interference relationship between the interference source cell and the interfered cell is clustered, and the interference source cell and the interfered cell are clustered, thereby simplifying the complex interference relationship, performing ABS configuration for the interference source cell in each cluster, and solving multiple cells. The AB S setting problem in the case of complex interference relationships improves the overall performance of the network.

Further, on the basis of the solution shown in FIG. 7, the embodiment of the present invention further provides a specific solution of the ABS configuration method. In this solution, the execution of 702-703 in the solution shown in FIG. The process is further refined, so as to accurately determine the interfered cell according to the cell load and the interfered user in the cell, and determine the interference source cell corresponding to the interfered cell according to different types of the interference source cell; wherein, 702 It can be specifically implemented as 7021 - 7028, and 703 can be specifically implemented as 7031 - 7036. As shown in FIG. 8, the method includes:

7 02 1 , using the cell information of the first cell, obtaining a cell load of the first cell.

The first cell is any one of the heterogeneous networks, and the cell load is a ratio of the number of resource blocks used by the cell to the total number of resource blocks of the cell. For example, the cell load is represented by L _c , the number of cell average used resource blocks is represented by R _a , and the total number of cell resource blocks is represented by N _c , then L _c = R _a / N _c .

7 022. Detect whether a cell load of the first cell is greater than a first threshold.

The first threshold is a threshold value of the cell load. If the cell load is greater than the first threshold, the cell may be an interfered cell, and further detection is required. If the cell load is less than or equal to the first threshold, It is determined that the cell is not an interfered cell. The first threshold can be set according to historical experience statistics, or it can be directly configured by the equipment operator. set up.

7 0 2 3, if the cell load of the first cell is greater than the first threshold, determining an interfered user in the first cell, and according to the source cell to which the interfered user is interfered, The interfered users are grouped to obtain at least one victim group.

The user of the interfered user is a user whose signal to interference and noise ratio is less than the second threshold. The second threshold is a critical value for determining whether the user is interfered. If the user's signal to interference and noise ratio is less than the second threshold, the user may be determined. The user is interfered by the signal of the neighboring cell; if the user's signal to interference and noise ratio is greater than or equal to the second threshold, it is determined that the user is not interfered by the neighboring cell signal.

The interfered users that are interfered by the same interference source cell or the same multiple interference source cells may be divided into one interference group, for example, the cell 1 includes the user 1 - 5 , and the neighbor cell of the cell 1 is the cell 2 And cell 3, where user 3 and user 4 are only interfered by cell 2, so user 3 and user 4 are assigned to interference group A; both user 5 and user 2 are only interfered by cell 2 and cell 3, so User 5 and User 1 are assigned to Interference Group B.

Wherein, if the cell load of the cell is less than or equal to the first threshold, it is determined that the cell is not the interfered cell.

7 0 2 4, determining whether the first cell satisfies the first condition and/or the second condition.

The cell may be divided into a macro cell and a micro cell. When the cell is a macro cell, the first condition is that the number of resource blocks occupied by the interfered users in the cell is greater than the threshold of the first macro cell, and the second condition is that at least one cell is in the cell. The number of resource blocks occupied by the interfering user is greater than the threshold of the second macro cell, and the threshold of the first macro cell is greater than or equal to the threshold of the second macro cell; When the cell is a micro cell, the first condition is that the number of resource blocks occupied by the interfered users in the cell is greater than the threshold of the first micro cell, and the second condition is that the number of resource blocks occupied by at least one interfered user in the cell is greater than the first The second micro cell threshold, the first micro cell threshold is greater than or equal to the second micro cell threshold.

Wherein, if the cell does not satisfy the first condition and/or the second condition, it is determined that the cell is not the 4th cell.

7 0 2 5, if the first cell meets the first condition and/or the second condition, determining that the first cell is the interfered cell.

When the cell only meets the first condition, determining that the cell is the interfered cell; when the cell only meets the second condition, determining that the cell is the interfered cell; when the cell satisfies the first condition and the second condition at the same time, determining The cell is an interfered cell.

7 0 2 6 , when the interfered cell satisfies the first condition and the second condition, determining that the source cell to which the target interfered user is interfered is the interference source cell corresponding to the interfered cell .

The number of resource blocks occupied by the target interfered user in the interfered cell is greater than the second threshold. That is, when the interfered cell satisfies the first condition and the second condition at the same time, the source cell that is interfered by the interfered user in the interfered cell that satisfies the second condition is the interferer cell of the interfered cell. The user information of the user in the cell may also include the interference strength of the cell interfered with by the user, and the interference strength of the interferer cell to the interfered cell may be the interference strength of the interfered user in the interfered cell that satisfies the second condition. . For example, cell 1 includes users 1 - 5, user 3 is the victim user, and user 3 is interfered by cell 2. Because the number of resource blocks occupied by cell 1 in user 3 is greater than the second threshold, cell 2 is determined to be a cell. Interference source cell of 1. The number of the interference source cells may also be one or multiple, and for example: the cell 1 includes users 1 - 5 , the user 3 is the interfered user, and the user 3 is interfered by the cell 2 and the cell 3 because the user 3 The number of resource blocks occupied by the cell 1 is greater than the second threshold, so it is determined that the cell 2 and the cell 3 are the interference source cells of the cell 1, that is, the interference of the cell 1 There are two source cells, namely cell 2 and cell 3.

7027, when the interfered cell only meets the first condition, sorting the interfered groups according to the number of resource blocks occupied by the interfered group, determining the first N of the interfered groups The interfered source cell is the interference source cell corresponding to the interfered cell.

Among them, the users in the cell are grouped in 7023, and the interfered group is obtained. When the interfered cell only satisfies the first condition, the interfered groups are sorted from large to small according to the number of resource blocks occupied by the interfered group, and the first N interfered groups are selected from the disturbed groups arranged from large to small. The interfered source cell, as the interferer cell of the interfered cell, N is a positive integer. The user information of the user in the cell may also include the interference strength of the cell interfered with by the user, and the interference strength of the interferer cell to the interfered cell may be the interference strength of the first N interfered groups selected by the interfered group. . For example: Cell 1 includes users 1-15, where user 1-4 is in victim group A, user 5-7 is in victim group B, user 8-1 Q is in victim group C, user 11- 15 In the disturbed group D, the interference group A, the interference group B, and the interference group (the number of resource blocks occupied by the interference group D are 12, 10, 13, and 20 respectively, and then the number of resource blocks occupied by the interference group is sorted, and The interference group D, the interference group (the interference group A, the interference group B, the N is 2, and the source cell to which the interference group D is interfered is the cell 2, and the source cells interfered by the interference group C are the cell 2 and the cell 3, Then, the interference source cell corresponding to the cell 1 is the cell 2 and the cell 3.

7028. When the interfered cell only meets the second condition, determining that the source cell that is interfered by the interfered group with the largest number of occupied resource blocks is the interference source cell corresponding to the interfered cell.

Wherein, when the interfered cell only meets the second condition, the source cell that is interfered by the interfered group with the largest number of occupied resource blocks in the interfered cell is used as the interference source cell of the interfered cell. The user information of the user in the cell may also include the interference strength of the interfering cell to the user, and the interference strength of the interfering cell to the interfered cell may be the interference of the interfered group with the largest number of resource blocks in the interfered cell. Strength. For example: Cell 1 includes users 1-10, where user 1-4 is in victim group A, user 5-7 is in victim group B, user 8-1 Q is in victim group C, and interference group A The number of resource blocks occupied by the interference group B and the interference group C is 12, 10, and 13, respectively. The interference group with the largest number of resource blocks is the interference group C, and the source cells interfered by the interference group C are the cell 2 and For cell 3, the interference source cell corresponding to cell 1 is cell 2 and cell 3.

7031. Obtain any one of the heterogeneous networks as a first cell set. One cell in the heterogeneous network may be an interference source cell; or may be an interfered cell; and may also be an interfered cell while being an interference source cell. Therefore, any one of the cells acquired in the heterogeneous network is an interference source cell and/or an interfered cell.

7032. Acquire a second cell set.

It should be noted that, when the M-th cell set is used as the interference source cell, the corresponding interfered cell exists in the first cell set to the M-th cell set, and the M-th cell set is used as the interfered cell. When the corresponding interference source cell does not exist, the case where the first cell is aggregated into the Mth cell group is divided into the same cluster. It is also within the scope of protection of this program. Similarly, when the M-th cell set is used as the interference source cell, the corresponding interfered cell does not exist, and the M-th cell set is the interfered cell, and the corresponding interference source cell exists in the first cell set to the M-th cell set. The case where the cells in the first cell set to the Mth cell set are divided into the same cluster also belong to the protection scope of the present solution.

There is also a cell 3; when the cell 7 is the interference source cell, the corresponding interfered cell is the cell 6, and when the cell 7 is the interfered cell, the corresponding interference source cell has no other interference source cell except the cell 2 and the cell 3; There is no corresponding interfered cell when the source cell is interfered, and the interference source cell corresponding to the cell 6 as the interfered cell is small. 7 addition, no other interfering cell; it into the cell clusters 1-7 A. The cell 8 is obtained, and when the cell 8 is used as the interference source cell, the corresponding 4th cell is the cell 9, the cell 8 is the cell of the interference source corresponding to the cell 4, and the cell 9 is the cell of the interference source. In addition to the cell 10, the interfering cell does not have other interfered cells. When the cell 10 is the interfered cell, the corresponding interferer cell does not have other interferer cells except the cell 9, so the cell 8-10 is divided into cluster B. .

It should be noted that there is a case where one cell is self-contained; there is also a case where there is no corresponding second cell set or third cell set in the first cell set. That is to say, at least one cell set is included in one cluster. It should be noted that there is only one cluster in a cell, that is, the same cell cannot exist in multiple clusters at the same time, and any one cell in the same cluster has interference relationship with other at least one cell in the same cluster, and each A cell in a cluster does not have an interference relationship with a cell in another cluster; or, a cell exists only in one cluster, that is, the same cell cannot exist in multiple clusters at the same time, and any one cell in the same cluster and the same cluster The other at least one cell has an interference relationship, and the interference strength between the cells in each cluster and the cells in other clusters is less than the interference strength threshold.

KP I can be the total network throughput, network fairness, etc. The total network throughput can be defined as
