现有技术利用各种干扰协调技术进行干扰控制， 降低小区之间的干扰 水平， 提高小区边缘用户的吞吐量。 小区间干扰协调的基本原理是： 将专 门分配给每个小区的优先用于边界用户的频率称为这个小区的主频率， 其 余频率称为次频率， 相邻小区的边界用户使用不同的主频率以避免小区间 干扰。 根据 3GPP R1-050507提出的软频率复用方案， 当每个小区的频率重 用因子为 3 时， 分配相邻 3个小区的边界用户占用各自正交的固定的 1/3 频率资源作为主频率资源优先分配给每个小区的边界用户。
但是， 由于分配给小区边界用户的主频率资源有限， 无法满足承载较 高负载的需求， 而对于负载需求小的小区， 会导致资源浪费。 发明内容

下面结合各个附图对本发明实施例技术方案的主要实现原理、 具体实 施方式及其对应能够达到的有益效果进行详细地阐述。
将总边缘频率资源分配到属于同一基站的多个小区时， 若为每个小区 分配固定的边缘频率资源， 则不能适应每个小区负载的变化， 无法满足承 载较高负载的小区的需求， 而对于负载需求小的小区， 又会导致资源浪费。 为了解决现有技术存在的问题， 本发明实施例提供了一种边缘频率资源分 配的方法， 如图 1所示， 该方法包括以下步骤：
步骤 101、 获取每个小区的边缘用户的频率资源需求；
具体的， 获取边缘频率资源时， 可以根据每个小区的边缘用户的业务 速率， 判断其需要分配的边缘频率资源。 当然， 也可以使用其他参数判断 每个小区需要分配的边缘频率资源， 例如业务量、 负载量、 发射功率等。 根据每个小区的边缘用户的业务速率， 判断需要分配的边缘频率资源 时， 首先获取属于同一基站的每个小区的边缘用户的业务速率， 然后获取 每个小区的边缘用户的业务速率与属于同一基站的所有小区的边缘用户的 总业务速率之间的比例关系， 最后根据所述每个小区的比例关系及总边缘 频率资源， 获取每个小区边缘用户的频率资源需求。 如图 2所示， 为属于 同一个基站的三个小区 A、 B、 C, 假设小区 A 的边缘用户的业务速率为 500kbps、 小区 B的边缘用户的业务速率为 250kbps、 小区 C的边缘用户的 业务速率为 250kbps, 则所有小区的边缘用户的总业务速率为 1000kbps, 其 中小区 A的比例关系为 500/1000=1/2, 小区 B的比例关系为 250/1000=1/4, 小区 C的比例关系为 250/1000=1/4; 若总边缘频率资源为 10M, 则小区 A 的边缘用户的频率资源需求为 5M, 小区 B 的边缘用户的频率资源需求为 2.5M, 小区 C的边缘用户的频率资源需求为 2.5M。
步骤 102、根据每个小区的边缘用户的频率资源需求， 以及每个小区与 相邻小区之间的干扰频率资源， 将总边缘频率资源依次分配到每个小区。
具体的， 将未分配边缘频率资源的小区中频率资源需求最大的小区作 为当前小区， 获取当前小区的边缘用户的频率资源需求、 以及已分配边缘 频率资源的小区的边缘用户的频率资源需求之和， 例如， 小区 A、 B、 C、 D中， 小区 A和 D已分配了边缘频率资源 , 小区 B和 C均未分配边缘频率 资源， 则比较小区 B和小区 C各自的频率资源需求， 将频率资源需求较大 的小区作为当前小区； 并且将已分配边缘频率资源的小区 A和小区 D各自 的边缘用户的频率资源需求求和。
并且， 获取当前小区与相邻小区之间的干扰频率资源； 当前小区与相 邻小区之间可能具有干扰， 占用一定的边缘频率资源， 该被占用的边缘频 率资源为干扰频率资源。 可以根据相邻基站发送的干扰信息， 获取当前小 区与相邻小区之间的干扰频率资源， 该干扰信息包括但不限于： 上行信道 中的高干扰指示和 /或下行信道中的相对窄带发送功率。 在为小区分配边缘 频率资源时， 将该干扰频率资源考虑进去， 有助于避免小区之间的干扰。
判断总边缘频率资源去除已分配边缘频率资源的小区的边缘用户的频 率资源需求之和、 干扰频率资源之后得到的剩余边缘频率资源， 是否不小 于当前小区的边缘用户的频率资源需求， 若剩余边缘频率资源不小于当前 小区的边缘用户的频率资源需求， 则按照当前小区的边缘用户的频率资源 需求分配边缘频率资源， 即将当前小区所需的边缘频率资源分配到该当前 小区； 若剩余边缘频率资源小于当前小区的边缘用户的频率资源需求， 则 将剩余边缘频率资源全部分配给当前小区， 并从当前小区与相邻小区之间 的干扰频率资源中， 获取当前小区的边缘用户的频率资源需求与剩余边缘 频率资源之间相差的边缘频率资源。
通过上述描述， 可以看出， 使用本发明实施例提供的边缘频率资源分 配的方法， 可以根据每个小区对边缘频率资源的需求而分配边缘频率资源， 避免了固定分配边缘频率资源带来的边缘频率资源不足或过多的问题， 同 时， 在合理分配边缘频率资源时， 充分考虑了相邻小区之间的干扰， 尽量 避免了小区之间的干扰。 进行详细说明， 如图 3所示， 小区 A0、 B0、 CO同属于基站 0, 小区 Al、 Bl、 CI同属于基站 1 , 依次类推， 假设总边缘频率资源为 10M, 各个小区 的具体情况如下：
小区 AO共有 3个边缘用户 UE: UE1具有 64kbps的 GBR ( Guaranteed Bit Rate,保证比特率）业务和 5Mbps 的 NGBR业务， 5Mbps 指的是 NGBR 业务的 AMBR ( Aggregate Maximum Bitrate, 汇聚最大比特速率）， 以下的 NGBR业务速率均和其相同； UE2具有 10Mbps的 NGBR业务； UE3具有 128kbps的 GBR业务和 10Mbps的 NGBR业务。 小区 BO共有 2个边缘用户 UE: UE1具有 1024kbps的 GBR业务和 5Mbps 的 NGBR业务； UE2具有 128kbps的 GBR业务和 10Mbps 的 NGBR 业务。
小区 CO共有 1个边缘用户 UE: UE1 具有 512kbps的 GBR业务和 10Mbps 的 NGBR业务。
基于上述假设， 使用本发明实施例提供的方法时， 如图 4所示， 包括 以下步骤：
步骤 401、 获取属于同一基站的每个小区的边缘用户的业务速率； 其中，小区 AO中 UE1业务速率为 5064kbps,即 64 +5000 =5064( kbps ); UE2业务速率为 10000kbps, UE3业务速率为 10128kbp,即 128+10000=10128 ( kbps ); 小区 A0的边缘用户的业务速率为 UE1、 UE2以及 UE3的业务速 率之和， 即小区 A0的边缘用户的业务速率 TA=5064+10000+10128=25192 ( kbps );
小区 B0中 UE1业务速率为 6024kbps, 即 1024 +5000 =6024 ( kbps ); UE2业务速率为 10128 kbps, 即 128 +10000 =10128 ( kbps ); 小区 B0的边 缘用户的业务速率为 UE1、 UE2的业务速率之和， 即小区 B0的边缘用户的 业务速率 TB=6024+10128=16152 ( kbps );
小区 CO中 UE1业务速率为 10512 kbps,即 512 +10000 =10512( kbps ); 小区 CO的边缘用户的业务速率 TC为 UE1业务速率 10512 kbps。
步骤 402、获取每个小区的边缘用户的业务速率与属于同一基站的所有 小区的边缘用户的总业务速率之间的比例关系；
小区 A0的比例关系为： TA / ( TA + TB + TC ) = 25192 / ( 25192 + 16152 + 10512 ) - 0.49;
小区 B0的比例关系为： TB / ( TA + TB + TC ) = 16152 / ( 25192 + 16152 + 10512 ) - 0.31 ; 小区 CO的比例关系为： TC / ( TA + TB + TC ) = 10512 / ( 25192 + 16152 + 10512 ) « 0.20。
步骤 403、根据每个小区的比例关系及总边缘频率资源， 获取每个小区 的边缘用户的频率资源需求； 具体的， 由于总边缘频率资源为 10M, 因此， 小区 A O的边缘用户的频率资源需求为 0.49*10=4.9M;小区 B0的边缘用户 的频率资源需求为 0.31*10=3.1M; 小区 CO的边缘用户的频率资源需求为 0.20*10=2M。
通过上述步骤可以获取到属于同一个基站 0 的所有小区各自的边缘用 户的频率资源需求。 可以使用 RB ( Resources Block, 资源块）表征上述边 缘频率资源， 一般情况下， 1M按照 5个 RB折算， 因此小区 A0的边缘用 户的频率资源需求为 5*4.9=24.5 « 25个 RB; 小区 C0的边缘用户的频率资 源需求为 5*2=10 个 RB； 小区 B0 的边缘用户的频率资源需求为 5*10-25-10=15个 RB。 确定了所有小区的边缘用户的频率资源需求后， 为 每个小区分配边缘频率资源， 继续执行以下步骤：
步骤 404、将未分配边缘频率资源的小区中频率资源需求最大的小区作 为当前小区； 小区 A0的边缘用户的频率资源需求为 25个 RB, 小区 B0的 边缘用户的频率资源需求为 15个 RB ,小区 C0的边缘用户的频率资源需求 为 10个 RB, 若小区 A0未分配边缘频率资源， 则小区 A0为当前小区； 若 小区 A0已分配边缘频率资源， 则小区 B0为当前小区； 若小区 A0、 B0均 已分配边缘频率资源， 则小区 C0为当前小区。 若无未分配边缘频率资源的 小区， 则说明边缘频率资源分配完毕。
步骤 405、获取当前小区的边缘用户的频率资源需求、 以及已分配边缘 频率资源的小区的边缘用户的频率资源需求之和；
具体的， 若小区 A0为当前小区， 则获取其边缘用户的频率资源需求为 25个 RB, 无已分配边缘频率资源的小区； 若小区 B0为当前小区， 则获取 其边缘用户的频率资源需求为 15个 RB , 已分配边缘频率资源的小区的边 缘用户的频率资源需求之和为 25个 RB; 若小区 CO为当前小区， 则获取其 边缘用户的频率资源需求为 10个 RB , 已分配边缘频率资源的小区的边缘 用户的频率资源需求之和为 40个 RB。
步骤 406、获取当前小区与相邻小区之间的干扰频率资源； 根据图 3可 知， 若小区 AO的相邻小区为小区 B5、 C6, 小区 BO的相邻小区为 A2、 C1 , 小区 CO的相邻小区为小区 A3、 B4; 当前小区所属的基站与相邻小区所属 的基站通过信息交互， 获取到相邻小区之间的干扰频率资源， 例如： 获取 相邻小区所属的基站发送的上行信道中高干扰指示和 /或下行信道中相对窄 带发送功率为 1的 RB个数。
上述步骤 405和步骤 406在执行时可以互换先后顺序。
步骤 407、判断总边缘频率资源去除已分配边缘频率资源的小区的边缘 用户的频率资源需求之和、 干扰频率资源之后得到的剩余边缘频率资源， 是否不小于当前小区的边缘用户的频率资源需求；若不小于，执行步骤 408； 若小于， 执行步骤 409;
具体的， 若小区 A0为当前小区， 则已分配边缘频率资源的小区的边缘 用户的频率资源需求之和为 0, 假设干扰频率资源为 2个 RB, 那么剩余边 缘频率资源为 48个 RB, 即 10*5-2=48个 RB, 不小于小区 AO的边缘用户 的频率资源需求 25个 RB; 若小区 B0为当前小区， 则已分配边缘频率资源 的小区的边缘用户的频率资源需求之和为 25个 RB,即小区 AO的边缘用户 的频率资源需求， 假设干扰频率资源为 5个 RB, 那么剩余边缘频率资源为 20个 RB, 即 10*5-25-5=20个 RB, 不小于小区 B0的边缘用户的频率资源 需求 15个 RB; 若小区 CO为当前小区， 则已分配边缘频率资源的小区的边 缘用户的频率资源需求之和为 40个 RB , 即小区 A0、 BO的边缘用户的频 率资源需求， 假设干扰频率资源为 6个 RB, 那么剩余边缘频率资源为 4个 RB, 即 10*5-25-15-6=4个 RB , 小于小区 CO的边缘用户的频率资源需求 10个 RB。
步骤 408、 按照当前小区的边缘用户的频率资源需求分配边缘频率资 源；
步骤 409、将剩余边缘频率资源全部分配给当前小区， 并从当前小区与 相邻小区之间的干扰频率资源中， 获取当前小区的边缘用户的频率资源需 求与剩余边缘频率资源之间相差的边缘频率资源。
重复上述步骤分配基站 0中的每个小区， 以及其他基站中的每个小区。 通过上述描述， 可以看出， 使用本发明实施例提供的边缘频率资源分 配的方法， 可以根据每个小区需求的边缘频率资源分配边缘频率资源， 避 免了固定分配边缘频率资源带来的边缘频率资源不足或过多的问题， 同时， 在合理分配边缘频率资源时， 充分考虑了相邻小区之间的干扰， 尽量避免 了小区之间的干扰。
下面通过另一具体实施例对本发明实施例提供的边缘频率资源分配的 方法进行详细说明， 如图 5所示， 小区 A0、 B0、 CO同属于基站 0, 小区 Al、 Bl、 CI 同属于基站 1 , 小区 A2、 B2、 C2同属于基站 2, 小区 A3、 B3、 C3同属于基站 3 , 并且小区 AO没有相邻小区， 小区 B0的相邻小区为 A2、 C1 , 小区 CO的相邻小区为 A3 , 4叚设总边缘频率资源为 10M, 各个小 区的具体情况与上一实施例相同，使用本发明实施例提供的方法时， 如图 6 所示， 包括以下步骤：
步骤 601、 获取小区 A0、 B0、 CO的边缘用户的业务速率；
其中，小区 A0中 UE1业务速率为 5064kbps,即 64 +5000 =5064( kbps ); UE2 业务速率为 10000kbps , UE3 业务速率为 10128kbps , 即 128+10000=10128 ( kbps ); 小区 A0 的边缘用户的业务速率为 UE1、 UE2 以及 UE3 的业务速率之和， 即小区 A0 的边缘用户的业务速率 TA=5064+10000+10128=25192 (kbps );
小区 BO中 UE1业务速率为 6024kbps, 即 1024 +5000 =6024 ( kbps ); UE2业务速率为 10128 kbps, 即 128 +10000 =10128 ( kbps ); 小区 BO的边 缘用户的业务速率为 UE1、 UE2的业务速率之和， 即小区 B0的边缘用户的 业务速率 TB=6024+10128=16152 ( kbps );
小区 CO中 UE1业务速率为 10512 kbps,即 512 +10000 =10512( kbps ); 小区 CO的边缘用户的业务速率 TC为 UE1业务速率 10512 kbps。
步骤 602、 分别获取小区 A0、 B0、 CO的边缘用户的业务速率与所有小 区的边缘用户的总业务速率之间的比例关系；
小区 AO的比例关系为： TA/(TA + TB + TC) = 25192/ (25192+ 16152
+ 10512) -0.49;
小区 B0的比例关系为： TB/(TA + TB + TC)= 16152/(25192+ 16152 + 10512) -0.31;
小区 CO的比例关系为： TC/(TA + TB + TC)= 10512/(25192+ 16152 + 10512) «0.20。
步骤 603、根据每个小区的比例关系及总边缘频率资源， 获取每个小区 的边缘用户的频率资源需求；
具体的， 由于总边缘频率资源为 10M, 因此， 小区 AO的边缘用户的频 率资源需求为 0.49*10=4.9M； 小区 B0 的边缘用户的频率资源需求为 0.31*10=3.1M; 小区 CO的边缘用户的频率资源需求为 0.20*10=2M。
通过上述步骤可以获取到属于同一个基站 0 的所有小区各自的边缘用 户的频率资源需求。可以使用 RB表征上述边缘频率资源，一般情况下， 1M 按照 5个 RB计算， 因此小区 A0的边缘用户的频率资源需求为 5*4.9=24.5 «25个 RB; 小区 C0的边缘用户的频率资源需求为 5*2=10个 RB; 小区 B0的边缘用户的频率资源需求为 5*10-25-10=15个 RB。确定了所有小区的 边缘用户的频率资源需求后， 为每个小区分配边缘频率资源， 继续执行以 下步骤：
步骤 604、 将小区 AO作为当前小区， 判断总边缘频率资源不小于小区 AO的边缘用户的频率资源需求， 按照小区 AO的边缘用户的频率资源需求 分配边缘频率资源；
具体的， 由于小区 AO的边缘用户的频率资源需求为 25个 RB, 大于小 区 B0、 CO各自的频率资源需求， 因此将小区 AO作为当前小区。 而且， 小 区 AO没有相邻小区， 所以， 在总边缘频率资源 50个 RB中随机选择 25个 RB分配到小区 AO即可。
步骤 605、将小区 B0作为当前小区，获取其边缘用户的频率资源需求、 与相邻小区的干扰频率资源以及小区 AO的边缘用户的频率资源需求；
具体的， 小区 B0的边缘用户的频率资源需求为 15个 RB, 不小于小区 CO的边缘用户的频率资源需求 10个 RB, 因此将小区 B0作为当前小区。 由图 5所示， 小区 B0的相邻小区为小区 A2、 C1 , 小区 BO所属的基站 0 与小区 A2所属的基站 2通过信息交互， 获取当前小区 B0与相邻小区 A2 之间 ΗΠ和 /或 RNTP为 1的 RB, 假设该干扰资源为 1个 RB; 小区 B0所 属的基站 0与小区 C1所属的基站 1通过信息交互， 获取当前小区 B0与相 邻小区 C1之间 ΗΠ和 /或 RNTP为 1的 RB假设该干扰资源为 2个 RB。
步骤 606、 判断总边缘频率资源去除小区 AO的边缘用户的频率资源需 求、 干扰频率资源之后得到的剩余边缘频率资源， 不小于当前小区 B0的边 缘用户的频率资源需求后， 在总边缘频率资源中， 将小区 B0的边缘用户所 需的频率资源分配到小区 B0;
具体的， 总边缘频率资源为 50个 RB , 小区 AO的边缘用户的频率资源 需求为 25个 RB, H没小区 B0的干扰频率资源为 3个 RB, 则剩余边缘频 率资源为 22个 RB , 大于小区 B0的边缘用户的频率资源需求 15个 RB。在 总边缘频率资源 50个 RB中随机选择 15个 RB分配到小区 B0。 步骤 607、将小区 CO作为当前小区，获取其边缘用户的频率资源需求、 与相邻小区的干扰资源以及小区 A0、 B0的边缘用户的频率资源需求之和； 具体的， 由图 5所示， 小区 CO的相邻小区为小区 A3 , 小区 CO所属的 基站 0与小区 A3所属的基站 3通过信息交互， 获取当前小区 CO与相邻小 区 A3之间 ΗΠ和 /或 RNTP为 1的 RB, 假设该干扰资源为 5个 RB。
步骤 608、 判断总边缘频率资源去除小区 A0、 B0的边缘用户的频率资 源需求之和、 干扰频率资源之后得到的剩余边缘频率资源， 小于当前小区 C0的边缘用户的频率资源需求后， 将剩余资源全部分配到小区 C0并在干 扰频率资源中获取相差的边缘频率资源。
具体的， 总边缘频率资源为 50个 RB , 小区 A0的边缘用户的频率资源 需求为 25个 RB , 小区 B0的边缘用户的频率资源需求为 15个 RB , 4叚设小 区 CO的干扰频率资源为 5个 RB ,则剩余边缘频率资源为 5个 RB, 小于小 区 CO的边缘用户的频率资源需求 10个 RB。 因此， 将剩余边缘频率资源全 部分配到小区 CO, 并且在干扰资源中随机选择 5个 RB分配到小区 C0。
通过上述描述， 可以看出， 使用本发明实施例提供的边缘频率资源分 配的方法， 可以根据每个小区的边缘频率资源需求分配边缘频率资源， 避 免了固定分配边缘频率资源带来的边缘频率资源不足或过多的问题， 同时， 在合理分配边缘频率资源时， 充分考虑了相邻小区之间的干扰， 尽量避免 了小区之间的干扰。
