Description

超级小区的拆分方法和装置 技术领域
本文涉及移动通信技术领域，尤其涉及一种超级小区的拆分方法和装置。
背景技术
LTE采用正交频分复用OFDM技术，每个子载波之间相互正交，使得小区内干扰不是LTE系统中产生干扰的主要因素，但在移动网络的多小区环境中小区之间的干扰始终存在，这种干扰会对网络性能产生严重的负面影响，当相同的频率资源被相邻的小区复用时LTE系统将产生干扰。
相关技术中为了消除小区间干扰提出一种超级小区组网方案，超级小区不依赖于基站通信，不依赖邻区无线资源使用状况，对终端透明，完全在基站侧实现，能够有效地减少小区间的干扰。每个超级小区由多个相邻的常规小区CP(cell-Portion)组成，位于超级小区中的常规小区等效于传统小区，这些超级小区中的常规小区能够像传统小区一样兼容无线传输方案，同时小区级专用资源能够在超级小区内的这些常规小区间共享，例如小区ID、主辅同步信号、跳频序列、加扰序列等。

本发明的较佳实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
本发明实施例提供一种超级小区的拆分方法。参照图1，图1为本发明实施例的超级小区的拆分方法的流程示意图。在该实施例中，所述超级小区 的拆分方法包括：
步骤S10、根据预设策略，以待拆分的超级小区为基础依次进行多次预拆分。
本实施例中所述预设策略包括：根据待拆分的超级小区中常规小区的数量M，以该待拆分的超级小区为基础进行M次预拆分，每次预拆分从待拆分的超级小区中拆分一个常规小区，每次预拆分所对应的被预拆分出的常规小区不同。例如设待拆分的超级小区由常规小区1、常规小区2、常规小区3组网形成，则需要以该待拆分的超级小区为基础进行3次预拆分，包括如下三次预拆分：一、将常规小区1从待拆分的超级小区中拆分出来，保留常规小区2和3；二、将常规小区2从待拆分的超级小区中拆分出来，保留常规小区1和3；三、将常规小区3从待拆分的超级小区中拆分出来，保留常规小区1和2。
步骤S20、针对每次预拆分，计算预拆分后的超级小区的载波干扰比和被预拆分出的常规小区的载波干扰比。
参见图2，图2为图1中步骤S20中计算预拆分后的超级小区的载波干扰比的具体细化流程示意图。其中步骤S20中计算预拆分后的超级小区的载波干扰比包括：
步骤S21、收集预拆分后的超级小区中每个UE(用户终端)上报的对应UE向预拆分后的超级小区中每个常规小区发送探测参考信号SRS/物理上行共享信道PUSCH的接收功率、预拆分后的超级小区的参考信号接收功率、传统邻区的参考信号接收功率。
本实施例中，所述预拆分后的超级小区中的每个UE通过最小化路测技术MDT功能能够测量获取该预拆分后的超级小区的参考信号接收功率，但无法测量获得该预拆分后的超级小区中每个常规小区的参考信号接收功率。为了获得预拆分后的超级小区中每个常规小区的参考信号接收功率，需要根据预拆分后的超级小区中每个常规小区中UE向每个常规小区发送探测参考信号SRS/PUSCH的接收功率计算每个常规小区中UE到每个常规小区的路损差ΔPL，然后根据每个常规小区中UE到每个常规小区的的路损差ΔPL和超级小区的参考信号接收功率，计算预拆分后的超级小区中每个常规小区的UE 接收每个常规小区的参考信号接收功率。
步骤S22、根据每个UE上报的UE向预拆分后的超级小区中每个常规小区发送SRS/PUSCH的接收功率确定每个UE所归属的常规小区。
本步骤S22中根据每个UE上报的UE向预拆分后的超级小区中每个常规小区发送SRS/PUSCH的接收功率，确定每个UE所归属的常规小区为：针对每一UE，比较该UE向超级小区中每个常规小区发送的发送SRS/PUSCH的接收功率的大小，其中最大SRS/PUSCH的接收功率所对应的常规小区即为该UE所归属的常规小区。假设预拆分的超级小区由常规小区1、2、3组网而成；该预拆分的超级小区的传统邻区包括传统邻小区4，某一UE上行发送SRS/PUSCH的功率为y，常规小区1收到UE的SRS/PUSCH功率为x1，常规小区2收到UE的SRS/PUSCH功率为x2，常规小区3收到UE的SRS/PUSCH功率为x3，比较x1、x2、x3的大小，若x1最大，则该UE归属于常规小区1。其中，该UE到常规小区1、常规小区2和常规小区3的路损分别为：PL1＝y-x1、PL2＝y-x2、PL3＝y-x3；UE到常规小区1、常规小区2和常规小区3的路损差为：ΔPL12＝PL1-PL2＝x2-x1；ΔPL13＝PL1-PL3＝x3-x1；ΔPL23＝PL2-PL3＝x3-x2。
步骤S23、根据每个UE上报的对应UE向预拆分后的超级小区中每个常规小区发送SRS/PUSCH的接收功率、预拆分后的超级小区的参考信号接收功率，计算每个常规小区中的UE接收所述超级小区中每个常规小区的参考信号接收功率。
如上所述本步骤S23中计算每个常规小区中的UE接收所述超级小区中每个常规小区的参考信号接收功率处理过程为：根据预拆分后的超级小区中每个常规小区中UE向每个常规小区发送SRS/PUSCH的接收功率，计算每个常规小区中UE到每个常规小区的路损差ΔPL，然后根据每个常规小区中UE的路损差ΔPL和每个常规小区中的UE接收到超级小区的参考信号接收功率，计算预拆分后的超级小区中每个常规小区UE接收到每个常规小区的参考信号接收功率。
某一常规小区中UE到每个常规小区的路损差处理过程如下：例如若某一UE归属于常规小区1，该UE上行发送SRS/PUSCH的功率为y，常规小 区1收到UE的SRS/PUSCH功率为x1，常规小区2收到UE的SRS/PUSCH功率为x2，常规小区3收到UE的SRS/PUSCH功率为x3，则该归属于常规小区1中的UE到常规小区1、常规小区2和常规小区3的路损为分别：PL1＝y-x1、PL2＝y-x2、PL3＝y-x3；该归属于常规小区1中的UE到常规小区1、常规小区2和常规小区3的路损差为：△PL12＝PL1-PL2＝x2-x1、△PL13＝PL1-PL3＝x3-x1、△PL23＝PL2-PL3＝x3-x2。即对于预拆分后的超级小区中的第m个常规小区，该第m个常规小区中某一UE到第i个常规小区的路损差为：△PLmi＝PLm-PLi＝xi-xm，其中，xm为第m个常规小区收到该某一UE的SRS/PUSCH功率，xi为第i个常规小区收到该某一UE的SRS/PUSCH功率，PLm为该某一UE到第m个常规小区的路损，PLi为该某一UE到第i个常规小区的路损，△PLmm＝0。
本实施例中，预拆分后的超级小区中每个常规小区中的UE接收每个常规小区的参考信号接收功率计算处理过程如下：
根据公式(1)计算预拆分后的超级小区中第m个常规小区中的UE接收到本小区(第m个常规小区)的参考信号接收功率：
Figure PCTCN2015078894-appb-000001
其中，RSRPS,m为预拆分的超级小区中第m个常规小区中UE接收到该预拆分的超级小区的参考信号接收功率；RSRPmm为第m个常规小区中UE接收到本小区(第m个常规小区)的参考信号接收功率；ΔPLmi为第m个常规小区中UE到本小区(第m个常规小区)与第m个常规小区中UE到第i个常规小区之间的路损差。其中所述RSRPS,m对第m个常规小区所有UE接收到的该预拆分的超级小区的参考信号接收功率进行求平均值计算获得；ΔPLmi通过对第i个常规小区收到UE的SRS/PUSCH功率xi与第m个常规小区收到UE的SRS/PUSCH功率xm进行相减计算获得；然后将计算获得的RSRPS,m和ΔPLmi通代入上式公式(1)即可计算出RSRPmm。
本实施例采用如下公式(2)计算第m个常规小区中UE接收的其他邻常规小区的参考信号接收功率：
RSRPmi＝RSRPmm+ΔPLmi------(2)；其中，1≤i<M；RSRPmi为第m个常规小区中UE接收的第i个常规小区(第m个常规小区的邻常规小区)的参考信号接收功率；RSRPmm为第m个常规小区中UE接收到本小区(第m个常规小区)的参考信号接收功率；ΔPLmi为第m个常规小区中UE到本小区(第m个常规小区)与第m个常规小区中UE到第i个常规小区之间的路损差。
本实施例中，每个常规小区的UE能够通过MDT功能测量获得每个传统邻区的参考信号接收功率，因此每个常规小区的UE接收每个传统邻区的参考信号接收功率可以通过相应的UE上报直接获得，本实施例以RSRP*mj代表第m个常规小区中UE接收的传统邻区(j)的参考信号接收功率。
步骤S24、根据每个常规小区中UE所接收的预拆分后的超级小区的参考信号接收功率、每个常规小区的参考信号接收功率、每个传统邻区的参考信号接收功率，计算预拆分后的超级小区的载波干扰比。
本步骤中首先计算该预拆分后的超级小区中每个常规小区的载波干扰比，每个常规小区的载波干扰比采用如下公式(3)进行计算。
Figure PCTCN2015078894-appb-000002
其中，CIm为根据第m个常规小区中某一UE上报的数据计算出该第m个常规小区的载波干扰比；RSRPS,m为第m个常规小区中的该某一UE接收到的超级小区的参考信号接收功率，RSRPmx为第m个常规小区中的该某一UE接收到的常规小区(x)的参考信号接收功率，
Figure PCTCN2015078894-appb-000003
为第m个常规小区中的该某一UE接收到所有传统邻区的参考信号接收功率。
本实施例中根据第m个常规小区中每个UE上报的数据计算出每个UE所对应的第m个常规小区的载波干扰比，然后对所有第m个常规小区的载波干扰比进行求平均值计算，计算获得的载波干扰比平均值即为第m个常规小区的载波干扰比。然后通过对拆分后的超级小区中的每个常规小区的载波干扰比进行求平均值计算获得的载波平均值，载波平均值即为预拆分后的超级小区的载波干扰比。
图3为图1中步骤S20计算预拆分后的常规小区的载波干扰比的具体细 化流程示意图。所述步骤S20计算被预拆分后的常规小区的载波干扰比包括：
步骤S201、收集被预拆分出的常规小区中UE接收本小区的参考信号接收功率、预拆分后的超级小区的参考信号接收功率、以及每个传统邻区的参考信号接收功率。
本实施例中，被预拆分出的常规小区中的UE中的MDT功能能够直接测量获取接收本小区的参考信号接收功率、预拆分后的超级小区的参考信号接收功率、以及每个传统邻区的参考信号接收功率。
步骤S202、根据所述被预拆分出的常规小区中UE接收本小区的参考信号接收功率、预拆分后的超级小区的参考信号接收功率、以及每个传统邻区的参考信号接收功率，计算该被拆分后的常规小区的载波干扰比。
本步骤S202采用如下公式(4)计算被拆分后的常规小区的载波干扰比：
Figure PCTCN2015078894-appb-000004
其中，C/Ix为根据从待拆分的超级小区中第x个常规小区(也即从待拆分的超级小区中拆分出来的常规小区)中某一UE上报的数据计算出该第x个常规小区的载波干扰比；RSRPS,x为第x常规小区中的该某一UE接收到的超级小区的参考信号接收功率，RSRPxx为第x常规小区中的该某一UE接收到本小区(第x个常规小区)的参考信号接收功率；
Figure PCTCN2015078894-appb-000005
为第x个常规小区中的某一UE接收到所有传统邻区的参考信号接收功率。
本实施例通过对被拆分后的常规小区(待拆分的超级小区中第x个常规小区)中每个UE上报的数据计算出的该被拆分后的常规小区的载波干扰比进行求平均值计算，计算获得的载波干扰比平均值，该载波干扰比平均值即为被拆分后的常规小区(待拆分的超级小区中第x个常规小区)的载波干扰比。
步骤S30、根据每次预拆分后对应的超级小区的载波干扰比和被预拆分出的常规小区的载波干扰比，确定正式待拆分的常规小区。
本实施例中，预先设置有用于判断预拆分后的超级小区载波干扰比是否满足该超级小区性能要求的第一载波干扰比阈值，以及预先设置有用于判断 被预拆分后的常规小区载波干扰比是否满足该常规小区性能要求的第二载波干扰比阈值。本步骤S30处理如下：针对每次预拆分，将预拆分后的超级小区的载波干扰比与预设的第一载波干扰比阈值进行比较，并将被预拆分出的常规小区的载波干扰比与预设的第二载波干扰比阈值进行比较；当预拆分后的超级小区的载波干扰比大于预设的第一载波干扰比阈值，且被预拆分出的常规小区的载波干扰比大于预设的第二载波干扰比阈值，则确认该次预拆分为可行拆分方案，当预拆分后的超级小区的载波干扰比小于或等于预设的第一载波干扰比阈值，或被预拆分出的常规小区的载波干扰比小于或等于预设的第二载波干扰比阈值，确认该次预拆分为不可行拆分方案；针对每次可行拆分方案，将预拆分后对应的超级小区的载波干扰比和被预拆分出的常规小区的载波干扰比进行相加，获得相应的总载波干扰比；比较所有可行拆分方案预拆分后对应的总载波干扰比的大小，确定总载波干扰比最大的可行拆分方案所对应的被预拆分出的常规小区为正式待拆分的常规小区。
步骤S40、将所述正式待拆分的常规小区从所述待拆分的超级小区中拆分。
本实施例中，若需要对已经正式拆分过一次的超级小区进行再一次的拆分，则可以将该已经正式拆分过一次的超级小区作为待拆分的超级小区返回执行上述步骤S10至步骤S40即可。
以上实施例提供的超级小区的拆分方法，通过根据预设策略，以待拆分的超级小区为基础依次进行多次预拆分；针对每次预拆分，计算预拆分后的超级小区的载波干扰比和被预拆分出的常规小区的载波干扰比；根据每次预拆分后对应的超级小区的载波干扰比和被预拆分出的常规小区的载波干扰比，确定正式待拆分的常规小区；将所述正式待拆分的常规小区从所述待拆分的超级小区中拆分的方式，能够实现将随着网络环境发生变化后不再适用的超级小区拆分为能够满足性能要求的新超级小区和常规小区，确保了系统资源被充分利用，能够有效地防止系统资源浪费的现象发生。
本发明实施例提供一种超级小区的拆分装置。参照图4，图4为本发明实施例的超级小区的拆分装置的功能模块示意图。在该实施例中，所述超级 小区的拆分装置100包括：预拆分模块110、计算模块120、确定模块130、拆分模块140。其中，所述预拆分模块110，设置为根据预设策略，以待拆分的超级小区为基础依次进行多次预拆分。所述计算模块120，设置为针对每次预拆分，计算预拆分后的超级小区的载波干扰比和被预拆分出的常规小区的载波干扰比。所述确定模块130，设置为根据每次预拆分后对应的超级小区的载波干扰比和被预拆分出的常规小区的载波干扰比，确定正式待拆分的常规小区。所述拆分模块140，设置为将所述正式待拆分的常规小区从所述待拆分的超级小区中拆分。
本实施例中，若需要对已经正式拆分过一次的超级小区进行再一次的拆分，则可以将该已经正式拆分过一次的超级小区作为待拆分的超级小区，然后再调用所述预拆分模块110、所述计算模块120、所述确定模块130、所述拆分模块140依次执行相关的操作。
上述实施例中所述预设策略为：根据待拆分的超级小区中常规小区的数量M，以该待拆分的超级小区为基础进行M次预拆分，每次预拆分从待拆分的超级小区中拆分一个常规小区，每次预拆分所对应的被预拆分出的常规小区不同。例如设待拆分的超级小区由常规小区1、常规小区2、常规小区3组网形成，则需要以该待拆分的超级小区为基础进行3次预拆分，包括如下三次预拆分：一、将常规小区1从待拆分的超级小区中拆分出来，保留常规小区2和3；二、将常规小区2从待拆分的超级小区中拆分出来，保留常规小区1和3；三、将常规小区3从待拆分的超级小区中拆分出来，保留常规小区1和2。
上述实施例中，所述计算模块120，是设置为收集预拆分后的超级小区中每个UE(用户终端)上报的对应UE向预拆分后的超级小区中每个常规小区发送探测参考信号SRS/物理上行共享信道PUSCH的接收功率、预拆分后的超级小区的参考信号接收功率、传统邻区的参考信号接收功率；根据每个UE上报的UE向预拆分后的超级小区中每个常规小区发送SRS/PUSCH的接收功率确定每个UE所归属的常规小区；根据每个UE上报的对应UE向预拆分后的超级小区中每个常规小区发送SRS/PUSCH的接收功率、预拆分后的超级小区的参考信号接收功率，计算每个常规小区中的UE接收所述超级小 区中每个常规小区的参考信号接收功率；根据每个常规小区中UE所接收的预拆分后的超级小区的参考信号接收功率、每个常规小区的参考信号接收功率、每个传统邻区的参考信号接收功率，计算预拆分后的超级小区的载波干扰比。
上述实施例中，所述预拆分后的超级小区中的每个UE通过最小化路测技术MDT功能能够测量获取该预拆分后的超级小区的参考信号接收功率，但无法测量获得该预拆分后的超级小区中每个常规小区的参考信号接收功率。为了获得预拆分后的超级小区中每个常规小区的参考信号接收功率，需要根据预拆分后的超级小区中每个常规小区中UE向每个常规小区发送SRS/PUSCH的接收功率计算每个常规小区中UE到每个常规小区的路损差△PL，然后根据每个常规小区中UE到每个常规小区的的路损差△PL和超级小区的参考信号接收功率，计算预拆分后的超级小区中每个常规小区的UE接收每个常规小区的参考信号接收功率。
所述计算模块120根据每个UE上报的UE向预拆分后的超级小区中每个常规小区发送SRS/PUSCH的接收功率，确定每个UE所归属的常规小区为：针对每一UE，比较该UE向超级小区中每个常规小区发送的发送SRS/PUSCH的接收功率的大小，其中最大SRS/PUSCH的接收功率所对应的常规小区即为该UE所归属的常规小区。例如假设预拆分的超级小区由常规小区1、2、3组网而成；该预拆分的超级小区的传统邻区包括传统邻小区4，某一UE上行发送SRS/PUSCH的功率为y，常规小区1收到UE的SRS/PUSCH功率为x1，常规小区2收到UE的SRS/PUSCH功率为x2，常规小区3收到UE的SRS/PUSCH功率为x3，比较x1、x2、x3的大小，若x1最大，则该某一UE归属于常规小区1。其中，该某一UE到常规小区1、常规小区2和常规小区3的路损分别为：PL1＝y-x1、PL2＝y-x2、PL3＝y-x3；UE到常规小区1、常规小区2和常规小区3的路损差为：△PL12＝PL1-PL2＝x2-x1；△PL13＝PL1-PL3＝x3-x1；△PL23＝PL2-PL3＝x3-x2。
所述计算模块120计算每个常规小区中的UE接收所述超级小区中每个常规小区的参考信号接收功率处理过程为：根据预拆分后的超级小区中每个常规小区中UE向每个常规小区发送SRS/PUSCH的接收功率，计算每个常规 小区中UE到每个常规小区的路损差△PL，然后根据每个常规小区中UE的路损差△PL和每个常规小区中的UE接收到超级小区的参考信号接收功率，计算预拆分后的超级小区中每个常规小区UE接收到每个常规小区的参考信号接收功率。
本实施例中某一常规小区中UE到每个常规小区的路损差处理过程如下：例如若某一UE归属于常规小区1，该UE上行发送SRS/PUSCH的功率为y，常规小区1收到UE的SRS/PUSCH功率为x1，常规小区2收到UE的SRS/PUSCH功率为x2，常规小区3收到UE的SRS/PUSCH功率为x3，则该归属于常规小区1中的UE到常规小区1、常规小区2和常规小区3的路损为分别：PL1＝y-x1、PL2＝y-x2、PL3＝y-x3；该归属于常规小区1中的UE到常规小区1、常规小区2和常规小区3的路损差为：△PL12＝PL1-PL2＝x2-x1、△PL13＝PL1-PL3＝x3-x1、△PL23＝PL2-PL3＝x3-x2。即对于预拆分后的超级小区中的第m个常规小区，该第m个常规小区中某一UE到第i个常规小区的路损差为：△PLmi＝PLm-PLi＝xi-xm，其中，xm为第m个常规小区收到该某一UE的SRS/PUSCH功率，xi为第i个常规小区收到该某一UE的SRS/PUSCH功率，PLm为该某一UE到第m个常规小区的路损，PLi为该某一UE到第i个常规小区的路损，△PLmm＝0。
本实施例中，所述计算模块120对预拆分后的超级小区中每个常规小区中的UE接收每个常规小区的参考信号接收功率计算处理过程如下：
根据公式(1)计算预拆分后的超级小区中第m个常规小区中的UE接收到本小区(第m个常规小区)的参考信号接收功率：
Figure PCTCN2015078894-appb-000006
其中，RSRPS,m为预拆分的超级小区中第m个常规小区中UE接收到该预拆分的超级小区的参考信号接收功率；RSRPmm为第m个常规小区中UE接收到本小区(第m个常规小区)的参考信号接收功率；ΔPLmi为第m个常规小区中UE到本小区(第m个常规小区)与第m个常规小区中UE到第i个常规小区之间的路损差。其中所述RSRPS,m对第m个常规小区所有UE接收到的 该预拆分的超级小区的参考信号接收功率进行求平均值计算获得；ΔPLmi通过对第i个常规小区收到UE的SRS/PUSCH功率xi与第m个常规小区收到UE的SRS/PUSCH功率xm进行相减计算获得；然后将计算获得的RSRPS,m和ΔPLmi通代入上式公式(1)即可计算出RSRPmm。
本实施例采用如下公式(2)计算第m个常规小区中UE接收的其他邻常规小区的参考信号接收功率：
RSRPmi＝RSRPmm+ΔPLmi------(2)；其中，1≤i<M；RSRPmi为第m个常规小区中UE接收的第i个常规小区(第m个常规小区的邻常规小区)的参考信号接收功率；RSRPmm为第m个常规小区中UE接收到本小区(第m个常规小区)的参考信号接收功率；ΔPLmi为第m个常规小区中UE到本小区(第m个常规小区)与第m个常规小区中UE到第i个常规小区之间的路损差。
本实施例中，每个常规小区的UE能够通过MDT功能测量获得每个传统邻区的参考信号接收功率，因此每个常规小区的UE接收每个传统邻区的参考信号接收功率可以通过相应的UE上报直接获得，本实施例以RSRP*mj代表第m个常规小区中UE接收的传统邻区(j)的参考信号接收功率。
本实施例中中首先计算该预拆分后的超级小区中每个常规小区的载波干扰比，每个常规小区的载波干扰比采用如下公式(3)进行计算。

其中，C/Im为根据第m个常规小区中某一UE上报的数据计算出该第m个常规小区的载波干扰比；RSRPS,m为第m个常规小区中的该某一UE接收到的超级小区的参考信号接收功率，RSRPmx为第m个常规小区中的该某一UE接收到的常规小区(x)的参考信号接收功率，

为第m个常规小区中的该某一UE接收到所有传统邻区的参考信号接收功率。
本实施例中首先根据第m个常规小区中每个UE上报的数据计算出每个UE所对应的第m个常规小区的载波干扰比，然后对所有第m个常规小区的载波干扰比进行求平均值计算，计算获得的载波干扰比平均值即为第m个常规小区的载波干扰比。然后通过对拆分后的超级小区中的每个常规小区的载 波干扰比进行求平均值计算获得的载波平均值，该载波平均值即为预拆分后的超级小区的载波干扰比。
上述实施例中，所述计算模块120，还设置为收集被预拆分出的常规小区中UE接收本小区的参考信号接收功率、预拆分后的超级小区的参考信号接收功率、以及每个传统邻区的参考信号接收功率；根据所述被预拆分出的常规小区中UE接收本小区的参考信号接收功率、预拆分后的超级小区的参考信号接收功率、以及每个传统邻区的参考信号接收功率，计算该被拆分后的常规小区的载波干扰比。其中被预拆分出的常规小区中的UE中的MDT功能能够直接测量获取接收本小区的参考信号接收功率、预拆分后的超级小区的参考信号接收功率、以及每个传统邻区的参考信号接收功率。本实施例中所述被拆分后的常规小区的载波干扰比采用如下公式(4)计算：
Figure PCTCN2015078894-appb-000009
其中，C/Ix为根据从待拆分的超级小区中第x个常规小区(也即从待拆分的超级小区中拆分出来的常规小区)中某一UE上报的数据计算出该第x个常规小区的载波干扰比；RSRPS,x为第x常规小区中的该某一UE接收到的超级小区的参考信号接收功率，RSRPxx为第x常规小区中的该某一UE接收到本小区(第x个常规小区)的参考信号接收功率；
Figure PCTCN2015078894-appb-000010
为第x个常规小区中的某一UE接收到所有传统邻区的参考信号接收功率。本实施例通过对被拆分后的常规小区(待拆分的超级小区中第x个常规小区)中每个UE上报的数据计算出的该被拆分后的常规小区的载波干扰比进行求平均值计算，计算获得的载波干扰比平均值，该载波干扰比平均值即为被拆分后的常规小区(待拆分的超级小区中第x个常规小区)的载波干扰比。
