Description

ICIC edge bandwidth resource allocation method and device

The present invention relates to a wireless communication LTE (Long Term Evolution) system technology or, in particular, to an ICIC (Inter-cell interference coordination) edge bandwidth resource allocation method and apparatus. Background technique

The LTE mobile communication system is shown in FIG. 1 and mainly includes: a core network, an access network, and a terminal. The core network mainly includes an MME (Mobility Management Entity) and an S-GW (Serving Gateway service gateway;), and an access network. It is composed of an eNB (Evolved Node B, an evolved base station, that is, a base station in LTE, which can be regarded as a node of a long-term evolution system), and the terminal is a UE (User Equipment), and the core network and the access network pass through the S1. The interfaces are interconnected, and different eNBs in the access network are interconnected through the X2 interface.

The ICIC technology utilizes the coordinated management and use restrictions of resources between cells to achieve the purpose of reducing small-area interference. The coordinated management and usage restrictions of resources are mainly manifested by the coordinating of the use of bandwidth resources by each cell and the limitation of the transmission power on different bandwidth resources. Among them, the coordination of bandwidth resources can improve the signal-to-interference ratio of some users to a certain extent and improve The data transmission rate of the cell edge user and the coverage of the cell.

According to d, the interval signaling overhead and the frequency of inter-cell communication, the inter-cell interference coordination can be divided into static interference coordination and semi-static interference coordination. Inter-cell interference coordination considers the whole cell to be divided into an inner circle closer to the base station and an outer ring farther from the base station. The user in the outer circle is called CEU (Cell Edge User), and the user in the inner circle is called For the CCU (Cell Center User, Central User). Generally, the CEU is subjected to large interference and the received signal has a small power. Therefore, it is considered to ensure orthogonality between resources allocated by users at neighboring cells, thereby reducing inter-cell spacing. The purpose of the interference. For ecu, since the received signal has a large power and the interference signal is small, the reutilization of the inner circle resources of the cell can be ensured, and the resource utilization rate is improved. Taking static interference coordination as an example, a part of the bandwidth needs to be reserved for the cell edge user, and the neighboring other cells cannot use the part of the bandwidth resource as the reserved bandwidth, and the cell center user can use all the frequency resources.

In the case of the intersection of several cells in the actual networking process, when the cell edge user resources are manually configured, the edge bandwidth resources of the adjacent two cells are the same, which causes the access and services of the edge users to be affected, thus affecting User's feelings.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail with reference to the drawings and preferred embodiments.

First embodiment

In the case of the same-band cell layout in a certain area of the LTE system as shown in FIG. 3, the sector of each eNB covers three mutually adjacent cells, that is, the eNB is located in three mutually adjacent cells. Central, the cell layout in Figure 3 may also be converged by the actual cell layout. The edge area of each cell is OC (out cell), and the center area is IC (inter cell). The bandwidth of each cell is 20M, and the total number of RBs (Resource Blocks, or resource blocks) is 100. The ICIC edge bandwidth resource allocation method in this embodiment, as shown in FIG. 2, includes the following specific steps:

Step S101: When performing network planning on the area, allocate a PCI (physical cell ID) to each of the three adjacent cells, and the allocated PCI must meet the following conditions: PCI pairs of the three adjacent cells The results of 3 ears 4 are different. For example, the number in the middle of each cell in Figure 3 is the allocated PCI that meets the above conditions. The PCI of the cell in the LTE system ranges from 1 to 504.

Step S102: The result of modulo PCI of the cell is used as the address number of the cell. As shown in FIG. 4, the number in the central blank of each cell is the address of the cell calculated in this step, step S103, and the bandwidth resources of 100 RBs are divided into four parts, as shown in FIG. 5, which are respectively RB set 1. RB set 2, RB set 3, and RB set 4, where RB set 1, RB set 2, and RB set 3 are edge resources, and RB set 4 is a central resource.

The RB number range of RB set 1 is [0~23], the RB number range of RB set 2 is [24~47], the RB number range of RB set 3 is [48~71], and the RB number range of RB set 4 is [72~99].

In this embodiment, a case is considered in which a resource resource allocation policy needs to separately allocate resources for a central area IC of a cell. According to other strategies, it is also possible to not allocate resources specifically for the central area IC of the cell. For example, all the bandwidth resources of 100 RBs are used for edge resources, and can be divided into three parts. As shown in FIG. 6, respectively, RB set 1, RB set 2, and RB set 3, if the average allocation mode is adopted, RB set 1 The RB number range is [0~31], the RB set 2 RB number range is [32~63], and the RB set 3 RB number range is [64~99], or may not be divided according to the average allocation method. For example: RB set 1 RB number range is [0~15], RB set 2 RB number The range is [16~35], and the RB number range of RB set 3 is [36~99].

Step S104: If the PCI mod 3 of a cell is 0, the RB resource in the RB set 1 is the resource that can be used by the cell edge area OC-0, and the result of the OC-0 indicating that the OCI of the cell is 3 ears is 0 is the edge area of the cell. When the user moves to the OC-0 area, it becomes the cell edge user of the area.

If the PCI mod 3 of a cell is 1, the RB resource of the RB set 2 is the resource that can be used by the cell edge area OC-1, and the OC-1 indicates that the result of the OCI of the cell is 1 when the result of the cell is 1. Edge area. When the user moves to the OC-1 area, it becomes the cell edge user of the area.

If a cell has a PCI mod 3 of 2, the RB resource of the RB set 3 is a resource that can be used by the cell edge area OC-2, and the OC-2 indicates that the result of the OCI of the cell is 2 when the result of the cell is 2 Edge area. When the user moves to the OC-2 area, it becomes the cell edge user of the area.

In Fig. 4, OC-0, OC-1 and OC-2 are respectively filled with different lines, and corresponding to the area filled with the corresponding lines in Fig. 5 and Fig. 6, the allocated bandwidth resource sets.

It should be noted that, in step S103 of the embodiment, 100 RBs are equally divided into four parts, but they are not necessarily equally divided, and may be arbitrarily divided into four parts, and only need to satisfy the RBs in the four sets that are divided. The number of RBs in each set is different, and the number of RBs in each set is greater than or equal to 1. The purpose is to ensure that the three sets belonging to the edge resources are different from each other when allocated to each of the three adjacent cells. Second embodiment

In the case of the same-band cell layout in a certain area of the LTE system as shown in FIG. 3, the sector of each eNB covers three mutually adjacent cells, that is, the eNB is located in the center of three mutually adjacent cells, and each cell The edge area is OC and the center area is IC. The bandwidth of each cell is 20M, and the total number of RBs is 100. The ICIC edge bandwidth resource allocation method in this embodiment, as shown in FIG. 7, includes the following specific steps:

Step S201, when performing network planning on the area, for each of three adjacent cells With PCI, the allocated PCI must meet the following conditions: The results of PCI for 3 neighboring cells are different for 3 ears. For example, the number in the central blank of each cell in Figure 3 is the allocated PCI that meets the above conditions. The PCI of the cell in the LTE system ranges from 1 to 504.

Step S202: The result of modulo PCI of the cell is used as the address number of the cell. As shown in FIG. 4, the number in the central blank of each cell is the address of the cell calculated in this step, step S203, and all the bandwidth resources of 100 RBs are used for edge resources, which can be divided into 9 parts, which are respectively RB sets. 1. The RB set 2 RB set 9 is allocated in an arbitrary allocation manner, for example, the RB number range of the RB set 1 after allocation is [0~11], and the RB number range of the RB set 2 is [12~19], The RB number range of RB set 3 is [20~27], the RB number range of RB set 4 is [28~39], the RB number range of RB set 5 is [40~47], and the RB number range of RB set 6 is [48~55], the RB number range of RB set 7 is [56~63], the RB number range of RB set 8 is [64~79], and the RB number range of RB set 9 is [80~99].

In step S204, the RB sets 1, 4, and 7 are classified into the first large group, the RB sets 2, 5, and 8 are classified into the second largest group, and the RB sets 3, 6, and 9 are classified into the third largest group.

Step S205: If the PCI mod 3 of a cell is 0, the resource of one RB set in the first large group may be a resource that can be used at the cell edge;

If the PCI mod 3 of a cell is 1, the resource of one RB set in the second largest group may be a resource available to the cell edge user;

If the PCI mod 3 of a cell is 2, the resource of one RB set in the third largest group may be a resource available to the cell edge user.

Preferably, a certain policy may also be adopted to sequentially select the RB set in the corresponding large group for different cells with the same modulus value. For example, in the edge bandwidth resource allocation process, the first cell that satisfies the PCI mod 3 is 0 takes the RB set. 1. The second cell that satisfies PCI mod 3 is 0 takes RB set 4, the third cell that satisfies PCI mod 3 is 0 takes RB set 7, and the fourth satisfies PCI mod 3 The cell of 0 takes the RB set 1, and so on, and then the corresponding RB set is cyclically selected in the first large group, which is convenient for automatically executing the above selected process. Third embodiment

In the case of the same-band cell layout in a certain area of the LTE system as shown in FIG. 9, the sector of each eNB covers four mutually adjacent cells, that is, the eNB is located at the center of four mutually adjacent cells. The bandwidth of each cell is 10M, and the total number of RBs is 50. The ICIC edge bandwidth resource allocation method in this embodiment, as shown in FIG. 8, includes the following specific steps:

Step S301: When network planning is performed on the area, each of the four adjacent cells is allocated PCI, and the allocated PCI must meet the following conditions: The results of the PCI of the four adjacent cells are different. For example, the number in the central blank of each cell in Figure 9 is the allocated PCI that meets the above conditions. The PCI of the cell in the LTE system ranges from 1 to 504.

Step S302: The result of modulo PCI 4 of the cell is used as the address number of the cell. As shown in Figure 10, the number in the central blank of each cell is the address number of the cell calculated in this step.

Step S303: All the bandwidth resources of the 50 RBs are used for the edge resources, and may be divided into 8 parts, which are respectively RB set 1, RB set 2 RB set 8, and allocate resources by using an arbitrary allocation manner, for example: RB set 1 after allocation The RB number range is [0~11], the RB set 2 RB number range is [12~19], the RB set 3 RB number range is [20~23], and the RB set 4 RB number range is [24~ 31], the RB number range of RB set 5 is [32~35], the RB number range of RB set 6 is [36~39], the RB number range of RB set 7 is [40~43], and the RB set of RB set 8 The range of numbers is [44~47].

Step S304, if the PCI mod 4 of a cell is 0, the resources of a set of RB sets may be taken as resources available to the cell edge user in the RB sets 0 and 4.

If the PCI mod 4 of a cell is 1, the resources of a set of RB sets may be taken in the RB set 1 and 5 as resources available to the cell edge user; If the PCI mod 4 of a cell is 2, the resources of a set of RB sets may be taken in the RB set 2, 6 as resources available to the cell edge user;

If the PCI mod 4 of a cell is 3, the resources of a set of RB sets can be taken as resources available to the cell edge users in RBs 3 and 7. Fourth embodiment

The general rule of the technical solution of the present invention can be summarized by the introduction of the above three embodiments. This embodiment introduces the ICIC edge bandwidth resource allocation method in a universal manner, and the sector of each eNB covers N mutually adjacent cells, each of which The total number of RBs in a cell is T. The ICIC edge bandwidth resource allocation method in this embodiment, as shown in FIG. 11, includes the following specific steps:

Step S401: When the PCI initial planning of the cell is planned, the results of the PCI pair N iM of the neighboring cells are different, respectively, being 0, 1 N-l.

Step S402, the entire bandwidth resource occupied by the cell is used for the cell edge user resource (the cell edge user resource is less than or equal to all the bandwidth resources occupied by the cell), and all the bandwidth resources occupied by the cell, that is, T RBs, may be divided into M sets. Where M=N < n, η is a natural number, that is, the bandwidth resource is from RB set 1 to RB set Μ. When the RBs are divided into M sets, the average allocation may be used, or may be arbitrarily allocated. Only the RBs in the M sets that are divided are different, and the number of RBs in each set is greater than or equal to 1.

Step S403: If the result of the PCI-to-N modulo of the cell is K (K can take 0, 1 N-1), then the RB set K+1, the set N+K+1, and the set 2N+K+1 set N

An optional set of (n-1) + K+1 is the bandwidth available to the user of the cell edge. Fifth embodiment
