Description
一种确定高干扰指示目标小区的方法、 系统及设备 技术领域
本发明涉及无线通信领域， 尤其涉及一种确定高干扰指示目标小区的 方法、 系统及设备。 背景技术
在当前长期演进（LTE, Long-Term Evolution ) Release 8的协议中， 月良 务小区的高干扰指示 ( HII, High Interference Information ) 目标小区（ target Cell ) 可以由增强型节点 （eNB, ehanced NodeB ) 决定。 eNB根据所述服 务小区的邻区列表中记载的各邻区信息， 将所述邻区列表中的各邻区信息 对应的邻区作为该服务小区的高干扰指示目标小区。 eNB 在确定服务小区 的高干扰指示目标小区后， 为了抑制高干扰指示目标小区对服务小区内 UE 的干扰， 向服务小区对应的各高干扰指示目标小区发送干扰抑制消息， 要 求高干扰指示目标小区根据接收到的干扰抑制消息， 调整自身发送信号的 相关参数， 以减少对 UE的干扰。
如图 1 所示为现有技术中服务小区和邻区的组网方式， 假设服务小区 为 CellO,服务小区的 6个邻区分别为 Celll~Cell6,则 eNB将确定这 6个邻 区 ( Celll , Cell2, Cell3 , Cell4, Cell5 , Cell6 )作为 CellO的高干扰指示目 标小区。
服务小区的邻区主要是根据小区之间的物理位置关系确定的， 一般情 况下， 可以将与服务小区之间的物理位置关系接近的小区作为邻区， 进而 将服务小区的邻区作为高干扰指示目标小区。 但实际上， 由于服务小区内 UE所在的位置不同， 邻区对服务小区内 UE的干扰也不同， 因此， 直接将 服务小区的邻区作为高干扰指示目标小区可能并不能真实地反映服务小区
中 UE受干扰的情况， 即 eNB确定的高干扰指示目标小区不准确。 进一步 地， 由于 eNB还需要向确定的高干扰指示目标小区发送干扰抑制消息， 而 部分高干扰指示目标小区可能对 UE的干扰较小，是无需接收干扰抑制消息 的， 导致额外增加了干扰抑制消息的数据量， 从而增加了接口信令的处理 开销， 加重了系统的负荷。
例如，如图 2所示， 为在如图 1所示的组网方式下， CellO是月良务小区， Celll~Cell6均为 CellO的邻区。 UE1、 UE2和 UE3是服务小区中的终端， UE1位于 CellO的中心， UE2和 UE3位于 CellO的边缘。 按照目前的方式， eNB会将 Celll~Cell6均确定为 CellO的高干扰指示目标小区， 但从图 2中 可以看出， UE1与各邻区距离较远， 受到各邻区的干扰较小， UE2和 UE3 受到 CellK Cell2和 Cell6的干扰较大， 受到 Cell3、 Cell4和 Cell5的干扰 较小。 此时， Cell3、 Cell4和 Cell5不应是 CellO的高干扰指示目标小区。
因此， 目前亟需引进一种可以准确判断高干扰指示目标小区的方案， 以克服简单地将邻区作为高干扰指示目标小区导致确定的高干扰指示目标 小区不准确的问题。 发明内容

具体实施方式
针对现有技术中将服务小区的邻区列表中的邻区作为该服务小区的高 干扰指示目标小区， 确定出的高干扰指示目标小区不准确的问题， 本发明 实施例提供的方案中， 利用服务小区中终端上报的测量报告来确定该服务 小区的高干扰指示目标小区， 由于所述测量报告中包括的信号测量值可以 真实反映该终端接收到的来自各小区的信号强度， 因此， 利用服务小区的 信号测量值与参考小区的信号测量值的差值小于设定值的方法， 可以确定 出对服务小区内的终端干扰较大的小区， 确定出的高干扰指示目标小区的 准确性较高。
下面结合说明书附图和各实施例对本发明技术方案进行详细说明。 本 发明各实施例中用于确定高干扰指示目标小区的设备可以为 eNB, 实施例 一至实施例三均以确定高干扰指示目标小区的设备为 eNB进行说明。
实施例一
本发明实施例一提供一种确定高干扰指示目标小区的方法， 该方法的 步驟流程如图 3所示， 具体包括以下步驟：
步驟 101、 终端测量信号测量值。
正在由某个小区提供服务的终端在需要进行小区切换或其他相关操作 时， 触发测量信号测量值的操作。 终端测量的信号测量值可以为信号接收 功率或信号接收质量，具体的，可以为参考信号接收功率（RSRP, Reference Signal Received Power ) 或参考信号接收质量 （RSRQ , Reference Signal Received Quality ), 用于表示终端在当前位置接收到的来自各小区的信号强 度。
正在为终端提供服务的小区可以称为该终端的服务小区， 参考小区可 以是发射的信号能够被所述终端接收到的所有小区， 也可以是 eNB确定出 的并通知给所述终端的小区。
在本步驟中， 终端可以测量自身所在服务小区的信号测量值， 来判断 当前服务小区提供的服务质量， 终端还可以测量能够接收到信号的至少一 个参考小区或者 eNB确定出的至少一个参考小区的信号测量值， 来判断自 身所在位置处受到其他小区的干扰情况。
步驟 102、 终端上报测量报告。
在本实施例中， 利用 eNB来确定高干扰指示目标小区， 因此， 在本步 驟中， 终端向 eNB上报测量报告， 该测量报告中包括终端测量的服务小区 的信号测量值，以及终端测量的至少一个参考小区的信号测量值，用于 eNB 来决策高干扰指示目标小区。
终端上报的测量报告中包括的至少一个参考小区的信号测量值是指： 终端测量的所有参考小区的信号测量值中， 大于第二设定值的参考小区的 信号测量值， 或者， 终端测量的所有参考小区的信号测量值中， 信号测量 值从大到小排在前 M位的 M个参考小区的信号测量值，所述 M为正整数。
当然， 根据目前协议的规定， 在本步驟中上报的参考小区的信号测量 值的数量应小于或等于 8个。
步驟 103、 eNB分别确定服务小区的信号测量值与所述至少一个参考小 区的信号测量值之差。
eNB 在接收到终端上报的测量报告后， 根据测量报告中包括的信号测 量值， 分别计算该终端测量的自身所在服务小区的信号测量值与各参考小 区的信号测量值的差值， 可以利用所述差值来表示服务 d、区与各参考 d、区 之间的干扰大小。
步驟 104、 eNB将确定的差值小于第一设定值的参考小区确定为所述服 务小区的高干扰指示目标小区。
在一般情况下， 服务小区的信号质量优于各参考小区， 因此服务小区 的信号测量值与各参考小区的信号测量值的差值为正值， 但本方案不排除
服务小区的信号测量值与各参考小区的信号测量值的差值为负值的情况， 不论所述差值为正值或负值， 均可以将确定的差值小于第一设定值的参考 小区确定为所述服务小区的高干扰指示目标小区。
在本实施例中， 若 eNB接收到来自多个终端分别上报的测量报告， 则步驟 103 具体包括： 针对每个终端上报的测量报告， 分别确定该测 量报告中服务小区的信号测量值与所述至少一个参考小区的信号测量值之 差。
步驟 104具体包括： 确定每个测量报告对应的待选参考小区， 所述待 选参考小区是对应的测量报告中， 信号测量值与服务小区的信号测量值之 差小于第一设定值的参考小区， 将确定的所有待选参考小区确定为所述服 务小区的高干扰指示目标小区， 或者， 根据每个测量报告对应的待选参考 小区， 确定各待选参考小区对应的测量报告数量， 将对应的测量报告数量 大于阈值的待选参考小区确定为所述服务小区的高干扰指示目标小区， 或 者， 将对应的测量报告数量从大到小排在前 N位的 N个待选参考小区确定 为所述服务小区的高干扰指示目标小区， 所述 N为正整数， 或者， 将每个 测量报告都对应的待选参考小区确定为所述服务小区的高干扰指示目标小 区。
下面通过两个具体的实例对本发明实施例一的方案进行详细说明。 如 图 4所示， 为本发明实施例二及实施例三中服务小区与参考小区的位置关 系示意图， 服务小区为 CellO, 参考小区为 Celll~ Cell8, 服务小区中包括终 端 UE1~UE4, 且终端在服务小区中所处的位置如图 4所示， 下面通过实施 例二对一个终端（UE2 )上报测量报告的情况对实施例一的方案进行详细说 明， 通过实施例三对多个终端 （UE1~UE4 )上报测量报告的情况对实施例 一的方案进行详细说明。
实施例二
本发明实施例二提供一种确定高干扰指示目标小区的方法， 该方法的 步驟流程如图 5所示， 具体包括以下步驟：
步驟 201、 UE2测量信号测量值。
在本步驟中， UE2可以测量 CellO的 RSRP值（记为 Rs ),及 Celll~Cell8 的 RSRP值（记为 i=l , 2... ... 8 ), RNi ( i=l , 2... ... 8 )与 Celll~Cell8 对应。
步驟 202、 UE2上才艮测量才艮告。
该测量报告中可以包括 UE2测量得到的服务小区的 、及测量得到的 全部参考小区的^ νι ~ ^ν8。
当然， 在本步驟中， 若参考小区的数量较多， 测量报告也可以仅包括 部分参考小区的 具体的， 可以将所有参考小区的 WM中， 大于第二设 定值的参考小区的 或者， 将所有参考小区的 WM中， WM最大的 M个 参考小区的信号测量值（所述 M为正整数）通过测量报告上报。
步驟 203、 eNB分别确定服务小区的信号测量值与各参考小区的信号测 量值之差。
步驟 204、 eNB将确定的差值小于第一设定值的参考小区确定为所述服 务小区的高干扰指示目标小区。
在本步驟中， 假设第一设定值为 H, 献满 RS - RM < 的 RNi , 若 确定 R肌 、 6和^ V8满足所述条件， 则^ νι、 6和^ V8对应的参考小区 Celll、 Cell6和 Cell8确定为所述服务小区的高干扰指示目标小区。
实施例三
本发明实施例三提供一种确定高干扰指示目标小区的方法， 该方法的 步驟流程如图 6所示， 具体包括以下步驟：
步驟 301、 UE1-UE4分别测量信号测量值。
在本步驟中， UE1~UE4可以分别测量 CellO的 RSRP值（记为 Rsl , 1=1 , 2... ...4 ), 及 Celll~Cell8的 RSRP值（记为 ^ , i=l , 2... ... 8 , 1=1 , 2... ...
4 ), 其中， UE1测量得到 CellO的 Rsl及 Celll~Cell8的 , 其他以 此类推。
步驟 302、 UE1~UE4分别上报测量报告。
UE1上报的测量报告中可以包括 UE1测量得到的服务小区的 及 测量得到的全部参考小区的^^ ~^¾8 , 类似的， 其他终端 UE2~UE4上报 的测量报告内容分别是各自测量得到的服务小区的 RSRP值和 8个参考小 区的 RSRP值。
步驟 303、 eNB针对每个终端上报的测量报告，分别确定该测量报告中 服务小区的信号测量值与所述至少一个参考小区的信号测量值之差。
步驟 304、 eNB确定每个测量报告对应的待选参考小区。
本步驟中， eNB 确定每个测量报告对应的待选参考小区的方法与实施 例二中步驟 204类似， 所述待选参考小区是对应的测量报告中， 信号测量 值与服务小区的信号测量值之差小于第一设定值的参考小区。
假设本步驟中， 针对 UE1上报的测量报告， 确定出的待选参考小区为 空；
针对 UE2上报的测量报告， 确定出的待选参考小区为 Celll、 Cell6和 Cell8;
针对 UE3上报的测量报告， 确定出的待选参考小区为 Celll、 Cell2、
Cell6和 Cell8;
针对 UE4上报的测量报告， 确定出的待选参考小区为 Celll、 Cell2、 Cell3和 Cell7。
步驟 305、 eNB确定高干扰指示目标小区。
在本步驟中， 可以有多种确定高干扰指示目标小区的方法， 包括但不 限于以下四种：
第一种、 将确定的所有待选参考小区确定为所述服务小区的高干扰指 示目标小区。
则， 在本步驟中将 Celll、 Cell2、 Cell3、 Cell6、 Cell7和 Cell8确定为 所述服务小区的高干扰指示目标小区。
第二种、 将对应的测量报告数量大于阈值的待选参考小区确定为所述 服务小区的高干扰指示目标小区。
在本步驟中，可以设定阈值为 1 , Celll对应的测量报告数量为 3 , Cell2、 Cell6和 Cell8对应的测量报告数量均为 2, Cell3和 Cell7对应的测量报告 数量均为 1 , 则将 Celll、 Cell2、 Cell6和 Cell8确定为所述服务小区的高干 扰指示目标小区。
第三种、 将对应的测量报告数量最大的 N个待选参考小区确定为所述 服务小区的高干扰指示目标小区。
假设 N取值为 4,则将对应的测量报告数量最大的 Celll以及对应的测 量报告数量次大 Cell2、 Cell6和 Cell8确定为所述服务小区的高干扰指示目 标小区。
第四种、 将每个测量报告都对应的待选参考小区确定为所述服务小区 的高干扰指示目标小区。
由于 UE1上报的测量报告对应的待选参考小区为空， 则， 根据第四种 方法， 确定出的所述服务小区的高干扰指示目标小区为空。
根据本发明实施例一至实施例三提供的方法， 可以提高确定出的高干 扰目标小区的准确性， 同时， 在服务小区内的多个终端上报测量报告时， eNB 可以针对每个测量报告（终端）确定待选参考小区， 并可以根据需要 来确定高干扰目标小区的判决条件： 可以将确定的所有待选参考小区确定
为所述服务小区的高干扰指示目标小区， 从而使得确定出的高干扰指示目 标小区可以涵盖全部对服务小区内终端产生干扰较大的小区； 可以将对应 的测量报告数量从大到小排在前 N位的 N个待选参考小区确定为所述服务 小区的高干扰指示目标小区， 从而可以确定对服务小区内大多数终端会产 生较大干扰的小区； 特殊的， 可以将每个测量报告都对应的待选参考小区 确定为所述服务小区的高干扰指示目标小区， 从而可以确定对上报测量报 告的每个终端都会产生较大干扰的小区， 从而将高干扰指示目标小区的范 围大大缩小， 减少后续需要发送的干扰抑制消息的数量； 还可以将对应的 测量报告数量大于阈值的待选参考小区确定为所述服务小区的高干扰指示 目标小区。 通过以上的高干扰指示目标小区的判决条件， 在提高判断高干 扰指示目标小区的准确性的同时， 提高了判断的灵活性。
