Description

一种小区间干扰协调方法、装置及服务器 技术领域
本申请涉及通信技术领域,特别涉及一种小区间干扰协调方法、装置及服务器。
背景技术
LTE(Long Term Evolution,长期演进)系统中,不同小区使用相同的频带资源,会导致小区间干扰,特别是小区边缘用户的同频干扰严重。为降低同频干扰对边缘用户的影响,目前常采用小区间干扰协调算法(即,ICIC算法),通过对上行/下行资源(如,频率资源/发射功率等)设置一定的约束,协调多个小区的行为,达到降低小区间干扰的目的。

具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
本申请实施例公开了一种小区间干扰协调方法,包括:确定边缘用户终端的最强干扰邻区,并确定所述最强干扰邻区的频域资源;根据所述边缘用户终端所属小区的物理小区标识,确定与所述最强干扰邻区的频域资源的重叠度不超过第一预设重叠度的频域资源,作为所述边缘用户终端的频域资源。在本申请中,降低最强干扰邻区对边缘用户终端的干扰,明显提高干扰协调的效果。
接下来对本申请实施例公开的小区间干扰协调方法进行介绍,请参见图1,可以包括:
步骤S11、确定边缘用户终端的最强干扰邻区,并确定所述最强干扰邻区所使用的频域资源。
最强干扰邻区可以理解为:对边缘用户终端干扰最大的邻区。
本实施例中,确定边缘用户终端的最强干扰邻区的过程,可以包括:
从边缘用户终端上报的测量结果中,获取边缘用户终端所属小区的各个邻区的信息;
根据边缘用户终端所属小区的各个邻区的信息,确定对边缘用户终端干扰最大的邻区,作为最强干扰邻区。
需要说明的是,从边缘用户终端上报的测量结果中,获取边缘用户终端所属小区的各个邻区的信息,进而根据边缘用户终端所属小区的各个邻区的信息,确定对边缘用户终端干扰最大的邻区,作为最强干扰邻区的方式,无需额外的信令开销及小区间干扰信息交互,方案简单易实现。
在确定边缘用户终端的最强干扰邻区之后,可以从最强干扰邻区上报的信息中确定出最强干扰邻区所使用的频域资源。
步骤S12、从所述边缘用户终端所属小区预先分配到的频域资源中,确定出与所述最强干扰邻区所使用的频域资源的重叠度不超过预设重叠度的频域资源,作为目标频域资源。
所述边缘用户终端所属小区预先分配到的频域资源,可以理解为:所述边缘用户终端所属小区可支配的频域资源。所述边缘用户终端所属小区可支配的频域资源可以由运营商预先分配。
目标频域资源不大于所述边缘用户终端所属小区预先分配到的频域资源。
预设重叠度可以根据调度需要,灵活设置。
需要说明的是,预设重叠度越小,目标频域资源与所述最强干扰邻区所使用的频域资源的重叠度越低,最强干扰邻区对边缘用户终端的干扰越小。
步骤S13、将所述边缘用户终端所使用的频域资源调整为所述目标频域资源。
将所述边缘用户终端所使用的频域资源调整为所述目标频域资源,可以尽量避免边缘用户终端与最强干扰邻区使用相同的频域资源。
在本申请中,在确定边缘用户终端的最强干扰邻区(可以理解为:对边缘用户终端干扰最大的邻区),并确定所述最强干扰邻区的频域资源之后,从边缘用户终端所属小区预先分配到的频域资源中,确定出与所述最强干扰邻区所使用的频域资源的重叠度不超过预设重叠度的频域资源,作为目标频域资源,保证目标频域资源与最强干扰邻区所使用的频域资源的重叠度低,在此基础上,将边缘用户终端所使用的频域资源调整为目标频域资源,尽量避免边缘用户终端与最强干扰邻区使用相同的频域资源,从而降低最强干扰邻区对边缘用户终端的干扰,明显提高干扰协调的效果。
进一步地,在降低最强干扰邻区对边缘用户终端的干扰的基础上,可以允许边缘用户终端和其他干扰弱的邻区使用相同的频域资源,因此边缘 用户终端所属小区不需要设置禁用带宽,不会导致整个小区的频谱效率下降。
在本申请的另一个实施例中,对上述最强干扰邻区所使用的频域资源进行介绍,具体可以为:
参考第一目标频域资源分配模板,从所述最强干扰邻区预先分配到的频域资源中分配到的频域资源。
所述第一目标频域资源分配模板为根据所述最强干扰邻区的物理小区标识,确定的频域资源分配模板。
所述最强干扰邻区预先分配到的频域资源可以理解为:最强干扰邻区可支配的频域资源。最强干扰邻区可支配的频域资源可以由运营商预先分配。
最强干扰邻区所使用的频域资源不大于最强干扰邻区预先分配到的频域资源。
本实施例中,可以为不同类型的小区设置不同的频域资源分配模板,保证不同类型的小区参考不同的频域资源分配模板,从小区预先分配到的频域资源中确定小区所使用的频域资源,进一步降低不同小区使用相同的频域资源的概率,降低不同小区之间的干扰。
本实施例中,可以通过物理小区标识来区分不同类型的小区。相应地,可以根据物理小区标识来确定小区的频域资源分配模板。
频域资源分配模板可以指示如何从小区预先分配到的频域资源中,分配频域资源,作为小区所使用的频域资源。
基于前述实施例介绍的最强干扰邻区所使用的频域资源,在本申请的另一个实施例中,对上述从所述边缘用户终端所属小区预先分配到的频域资源中,确定出与所述最强干扰邻区所使用的频域资源的重叠度不超过预设重叠度的频域资源,作为目标频域资源进行介绍,具体可以包括:
A11、确定所述边缘用户终端所属小区的物理小区标识对应的频域资源分配模板,为第二目标频域资源分配模板。
如前述实施例所述,不同类型小区对应的频域资源分配模板不同,因 此本步骤需要确定所述边缘用户终端所属小区的物理小区标识对应的频域资源分配模板,为第二目标频域资源分配模板。
A12、参考所述第二目标频域资源分配模板,从所述边缘用户终端所属小区预先分配到的频域资源中,确定出与所述最强干扰邻区所使用的频域资源的重叠度不超过预设重叠度的频域资源,作为目标频域资源。
参考所述第二目标频域资源分配模板,从所述边缘用户终端所属小区预先分配到的频域资源中,确定出与所述最强干扰邻区所使用的频域资源的重叠度不超过预设重叠度的频域资源,作为目标频域资源,可以提高目标频域资源确定的效率,从而提高小区间干扰协调的效率。
在本申请的另一个实施例中,对上述第一目标频域资源分配模板和第二目标频域资源分配模板进行介绍,具体如下:
所述第一目标频域资源分配模板可以包括:
第一频域资源起始分配位置及第一频域资源分配方向。
参考第一目标频域资源分配模板,从最强干扰邻区预先分配到的频域资源中分配小区所使用的频域资源,可以理解为:从最强干扰邻区预先分配到的频域资源中的第一频域资源起始分配位置开始,按照第一频域资源分配方向,分配小区所使用的频域资源。
所述第二目标频域资源分配模块可以包括:
第二频域资源起始分配位置及第二频域资源分配方向。
参考第二目标频域资源分配模板,从边缘用户终端所属小区预先分配到的频域资源中分配小区所使用的频域资源,可以理解为:从边缘用户终端所属小区预先分配到的频域资源中的第二频域资源起始分配位置开始,按照第二频域资源分配方向,分配小区所使用的频域资源。
需要说明的是,由于预先分配到的频域资源相同的各个小区之间容易产生干扰,为了减少预先分配到的频域资源相同的各个小区之间的干扰,目前一般根据物理小区标识模三的结果,来调整各个小区所使用的频域资源。因此,具体可以为物理小区标识模三的结果不同的小区,设置不同的频域资源分配模板。物理小区标识模三的结果不同的小区,则可以参考各 自的频域资源分配模板,从小区预先分配到的频域资源中确定小区所使用的频域资源。基于此,在本申请的另一个实施例中,在所述最强干扰邻区预先分配到的频域资源和所述边缘用户终端所属小区预先分配到的频域资源相同的情况下,对上述第一频域资源起始分配位置及第一频域资源分配方向,及第二频域资源起始分配位置及第二频域资源分配方向进行介绍,具体可以包括:
