5101、获取第一小区对应的第一频率资源使用模式，其中，该第一小区与其相邻小区的频率资源使用模式不同。 The first frequency resource usage mode corresponding to the first cell is obtained, where the frequency resource usage mode of the first cell and the neighboring cell is different.

在本实施例中，优选的，可以根据具体情况预设至少一种频率资源使用模式，以使得相邻小区的频率资源使用模式不同。需要说明的是该第一小区可以表示任一小区。 In this embodiment, preferably, at least one frequency resource usage mode may be preset according to a specific situation, so that frequency resource usage modes of neighboring cells are different. It should be noted that the first cell may represent any cell.

5102、根据频率资源使用模式和频率资源的映射关系，获取第一小区对应的第一频率资源使用模式对应的第一频率资源，并将上述第一频率资源分配给该第一小区。 The first frequency resource corresponding to the first frequency resource usage mode corresponding to the first cell is obtained according to the mapping relationship between the frequency resource usage mode and the frequency resource, and the first frequency resource is allocated to the first cell.

具体的，获取第一小区对应的频率资源使用模式，可以是获取了该第一小区对应的频率资源使用模式的编号，进一步根据该模式的编号去查询该模式具体所对应的频率资源，即根据频率使用模式和频率资源的映射关系，以获取对应的频率资源。 Specifically, acquiring a frequency resource usage mode corresponding to the first cell, where the first The number of the frequency resource usage mode corresponding to the cell, and further querying the frequency resource corresponding to the mode according to the number of the mode, that is, according to the mapping relationship between the frequency usage mode and the frequency resource, to obtain the corresponding frequency resource.

本实施例中，通过获取第一小区对应的频率资源使用模式，再根据频率资源使用模式和频率资源的映射关系，获取第一小区频率资源使用模式对应的频率资源，并将该频率资源分配给该第一小区，由于该第一小区与其相邻小区的频率资源使用模式不相同，小区间的干扰尽可能降低，从而小区平均速率和边缘用户速率均得到明显提高。 In this embodiment, the frequency resource usage mode corresponding to the first cell is obtained, and the frequency resource corresponding to the frequency resource usage mode of the first cell is obtained according to the mapping relationship between the frequency resource usage mode and the frequency resource, and the frequency resource is allocated to the frequency resource. The first cell, because the frequency resource usage mode of the first cell and its neighboring cell is different, the interference of the small interval is reduced as much as possible, so that the average cell rate and the edge user rate are significantly improved.

图 2为本发明提供的资源分配方法基于的场景示意图，本发明实施例的具体应用场景是基站间距离很小的网络中，需要说明的是，本实施例中预设三种频率资源使用模式，可以对着三种模式进行编号：模式 0、模式 1和模本发明实施例主要以三种不同的频率资源使用模式为例进行说明。 2 is a schematic diagram of a scenario based on a resource allocation method provided by the present invention. The specific application scenario of the embodiment of the present invention is a network with a small distance between base stations. It should be noted that, in this embodiment, three frequency resource usage modes are preset. The three modes can be numbered: mode 0, mode 1, and mode. The embodiment of the present invention mainly uses three different frequency resource usage modes as an example.

如图 2所示，其中，每一个六边形表示一个小区，箭头指示方向表示天线主辦方向。 As shown in Fig. 2, each hexagon represents a cell, and the arrow indicates the direction indicating the direction in which the antenna is hosted.

一个小区可以有 6个相邻的小区，而两两相邻的小区有 3个。此种情况下，预设三种频率资源使用模式，可以使得相邻的小区使用不同的频率资源；或者，另一种情况下，如图 2所示，其中阴影部分可以表示一个基站（比如 eNB )下包含的 3个小区，假设为第一小区、第二小区、第三小区，其中，三个小区互为相邻小区。同时，预设三种频率资源使用模式，为第一小区分配第一频率资源，例如是模式 0对应的频率资源；为第二小区分配第二频率资源，例如是模式 1对应的频率资源；为第三小区分配第三频率资源，例如是模式 2对应的频率比资源，这样就可以使得相邻的小区使用不同的频率资源。 A cell can have six adjacent cells, and two adjacent cells have three. In this case, three frequency resource usage modes are preset, so that adjacent cells use different frequency resources; or, in another case, as shown in FIG. 2, the shaded portion may represent a base station (such as an eNB). The three cells included in the following are assumed to be the first cell, the second cell, and the third cell, where the three cells are neighboring cells. At the same time, the three frequency resource usage modes are preset, and the first frequency resource is allocated to the first cell, for example, the frequency resource corresponding to the mode 0; the second frequency resource is allocated to the second cell, for example, the frequency resource corresponding to the mode 1; The third cell allocates a third frequency resource, for example, a frequency ratio resource corresponding to mode 2, so that adjacent cells can use different frequency resources.

进一步地，在本发明另一实施例中， S101的一种具体实现方式为：根据该第一小区的身份标识码（ Identity , 简称 ID ) , 釆用公式 M=cell— ID mod 3 , 获取与该第一小区对应的第一频率资源使用模式 Μ。 Further, in another embodiment of the present invention, a specific implementation manner of the S101 is: obtaining, according to the identity code (ID, ID) of the first cell, using the formula M=cell_ID mod 3 The first frequency resource usage mode corresponding to the first cell is Μ.

其中， cell— ID表示上述第一小区的 ID, mod表示取余运算， M为整数，具体的 cell— ID mod 3的结果只可能有 0、 1、 2三种，刚好对应上述模式 0、模式 1和模式 2, 即如果求得 M为 0, 那么该第一小区使用的 (即对应的）第一频率资源使用模式为模式 0, 这样在一般场景下就可以实现相邻小区所使用的模式不同。 The cell_ID indicates the ID of the first cell, mod indicates the remainder operation, and M is an integer. The result of the specific cell-ID mod 3 may only be 0, 1, or 2, which corresponds to the mode 0, mode. 1 and mode 2, that is, if M is found to be 0, then the first cell is used (ie corresponding) The first frequency resource usage mode is mode 0, so that the mode used by the neighboring cells can be different in a general scenario.

可选的，当上述频率资源为物理上行共享信道（Physical Uplink Shared Channel, 简称 PUSCH )资源块（ Resource Block, 简称 RB)时， S 101之前，该方法还包括： Optionally, when the foregoing frequency resource is a Physical Uplink Shared Channel (PUSCH) Resource Block (RB), before the S101, the method further includes:

根据***内每个 PUSCHRB的频率大小，按照从小到大的顺序，对上述 ***带宽内的 N个 PUSCH RB进行排序，对于排序后的 PUSCH RB,按照频率从小到大依次给每个上述 PUSCHRB分配一个序号；具体地，上述***可以是 LTE***。 According to the frequency of each PUSCH RB in the system, the N PUSCH RBs in the system bandwidth are sorted according to the order from small to large. For the sorted PUSCH RBs, each PUSCH RB is allocated one by one according to the frequency from small to large. The serial number; specifically, the above system may be an LTE system.

具体地，频率资源使用模式和频率资源的映射关系包括：第一频率资源使用模式和该第一频率资源使用模式对应的第一频率资源；第二频率资源使用模式和该第二频率资源使用模式对应的第二频率资源；第三模式和该第三频率资源使用模式对应的第三频率资源； Specifically, the mapping relationship between the frequency resource usage mode and the frequency resource includes: a first frequency resource usage mode and a first frequency resource corresponding to the first frequency resource usage mode; a second frequency resource usage mode and the second frequency resource usage mode Corresponding second frequency resource; a third mode and a third frequency resource corresponding to the third frequency resource usage mode;

其中，模式 0, 即第一频率资源使用模式中，对应的第一频率资源包括序号为 ceil(N * x)的 PUSCH RB； Wherein, mode 0, that is, in the first frequency resource usage mode, the corresponding first frequency resource includes a PUSCH RB with a sequence number ceil(N*x);

举例来说，以 N=90, x=l/2为例，模式 0中，第一频率资源包括序号为 l~ 7(90*丄）的 PUSCH RB, 即 1〜45 号的 PUSCH RB；模式 1 中， For example, taking N=90, x=l/2 as an example, in mode 0, the first frequency resource includes a PUSCH RB with a sequence number of l~7 (90*丄), that is, a PUSCH RB of 1 to 45; 1 in,

2 ce/(— + 90*-)-75 , 小于 90 , 因此，对应的第二频率资源包括序号为 3 2 ceil(—) + 1 ~ ceil(— +90*-)的 PUSCH RB, 即 31〜75号的 PUSCH RB; 模式 2 3 3 2 中，《^7( *90 + 90*丄) = 105, 大于 90, 因此，对应的第三频率资源包括序号为 2 ce / (- + 90 * -) - 75 , less than 90 , therefore, the corresponding second frequency resource includes PUSCH RB with sequence number 3 2 ceil(-) + 1 ~ ceil(- +90*-), ie 31 PUSCH RB of ~75; in mode 2 3 3 2, "^7( *90 + 90*丄) = 105, greater than 90, therefore, the corresponding third frequency resource includes the sequence number

需要说明的是，可以看出上述三种模式中使用的频率资源可以有部分重合，因为如果完全重合会使小区间的干扰严重，如果完全不重合又会造成每个小区分到的频率资源太少，因此本实施例中综合考虑了干扰问题，和频率资源问题，根据经验和具体应用场景设定合适的 X值，确定一个较为优选的方案。如图 3所示，为 x=l/3时，频率资源使用模式和频率资源的映射关系，此时，三种模式中的频率资源完全不重合。如图 4所示，为 1/3<χ 2/3时，频率资源使用模式和频率资源的映射关系，此时，三种模式中的频率资源部分重合。如图 5所示，为 x>2/3时，频率资源使用模式和频率资源的映射关系，此时，三种模式中的频率资源部分重合。 It should be noted that the frequency resources used in the above three modes may partially overlap, because if the coincidence is complete, the inter-cell interference will be severe, and if not completely coincident, the frequency resources allocated to each cell will be too Therefore, in this embodiment, the interference problem and the frequency resource problem are comprehensively considered, and an appropriate X value is set according to experience and a specific application scenario to determine a more preferable solution. As shown in FIG. 3, when x=l/3, the mapping relationship between the frequency resource usage mode and the frequency resource, at this time, the frequency resources in the three modes do not coincide at all. As shown in Fig. 4, when 1/3 < χ 2/3, the mapping relationship between the frequency resource usage pattern and the frequency resource, at this time, the frequency resource portions of the three modes overlap. As shown in FIG. 5, when x>2/3, the frequency resource usage pattern and the frequency resource are mapped, and at this time, the frequency resources in the three modes partially overlap.
