Description

干扰协调方法、 装置和系统 技术领域
本发明实施例涉及通信技术领域， 并且更具体地， 涉及干扰协调方法、 装置和系统。 背景技术
随着移动通信与宽带无线接入技术的各自的发展， 两者的业务互相渗 透， 为了满足移动通信宽带化的需求并应对宽带通信移动化的挑战， 移动通 信技术引入了 LTE ( Long Term Evolution, 长期演进）通信系统。
在 LTE通信系统中， 由于采用了 OFDM ( Orthogonal Frequency Division Multiplexing, 正交频分复用）技术， 使得各子信道之间正交， 从而较好的解 决了小区内干扰的问题。然而， LTE系统对频谱利用率有较高的要求， 因此， 引入了同频组网的方式来提高频谱利用率， 然而却引入了小区间干扰的问 题。 例如， 如果相邻小区在它们覆盖的重叠区域使用相同的频谱资源， 则该 重叠区域将产生严重的 ICI ( Inter-Cell Interference , 小区间干扰）。 可见， 在 LTE通信系统中， 影响系统性能的主要干扰来自小区间干扰。
因此， 如何降低小区间的干扰， 以提高系统的服务性能， 特别是小区边 缘区域的性能， 是 LTE系统亟待解决的重要问题。 发明内容

下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行 清楚、 完整地描述， 显然， 所描述的实施例是本发明一部分实施例， 而不是 全部的实施例。 基于本发明中的实施例， 本领域普通技术人员在没有作出创 造性劳动前提下所获得的所有其他实施例， 都属于本发明保护的范围。 应理解，本发明实施例的技术方案可以应用于各种通信系统，例如： GSM ( Global System for Mobile Communications, 全球移动通信） 系统、 CDMA ( Code Division Multiple Access ,码分多址）系统、 WCDMA ( Wideband Code Division Multiple Access, 宽带码分多址）系统、 GPRS ( General Packet Radio Service , 通用分组无线业务）、 LTE 系统、 LTE FDD ( Frequency Division Duplex, 频分双工） 系统、 LTE TDD ( Time Division Duplex, 时分双工）、 UMTS ( Universal Mobile Telecommunications System, 通用移动通信系统 ) 等。 应理解， 本发明对此并不限定。
在本发明实施例中， UE可称之为终端（ Terminal )、 MS ( Mobile Station, 移动台）、 移动终端（ Mobile Terminal )等， 该用户设备可以经 RAN ( Radio Access Network, 无线接入网）与一个或多个核心网进行通信， 例如， 用户 设备可以是移动电话（或称为 "蜂窝" 电话）、 具有移动终端的计算机等， 例如， 用户设备还可以是便携式、 袖珍式、 手持式、 计算机内置的或者车载 的移动装置， 它们与无线接入网交换语音和 /或数据。
基站可以是 GSM或 CDMA中的 BTS ( Base Transceiver Station,基站；)， 也可以是 WCDMA中的 NB( NodeB ,基站）或者 UMTS中的 BS( Base Station, 基站；)， 还可以是 LTE中的 eNodeB ( Evolutional Node B , 演进型基站；)， 也 称为 eNB , 等等， 本发明并不限定。
在本发明实施例中，一个部件与另一部件之间（例如本发明的模块之间） 的连接，可包括有线和 /或无线方式的连接。有线方式可包括但不限于各种介 质构成的线缆， 如光纤、 导电线缆或半导体线路等； 或者包括其他形式， 如 内部总线、 电路、 背板等。 无线方式是能够实现无线通信的连接方式， 包括 但不限于射频、 红外线、 蓝牙等。 两个部件之间可存在内部或外部的接口， 所述接口可以是物理接口或逻辑接口。
目前， UE根据网络侧配置的测量事件进行测量上报， 但是每个测量事 件都有其进入条件， 从而导致小区中的所有 UE并非都会进行测量上报。 举 例而言， A3 事件的进入条件为邻小区测量结果高于服务小区测量结果的预 设门限值。 如此， 小区中的中心 UE将不会满足这个进入条件， 从而不会进 行测量上报。 如此， 在利用下行信道信息估计网络性能时， 实际上忽略了中 心 UE受到邻区的干尤。 可见， 在网络性能的估计过程中， 网络性能评估的 准确性可以进一步提高， 从而更加有效的降低小区间的干扰， 提供通信系统 的服务性能。
有鉴于此， 本发明以下实施例中， 利用小区上行 RS ( Reference Signal, 参考信号 ) 的测量结果代替 UE下行 RS的测量结果来估计网络性能， 从而 确定每个小区的下行发射功率。 上行 RS测量相对于下行 RS测量， 在稳定 性和测量精度上均有优势，且每个小区的中心 UE都可以发送上行参考信号， 因此该小区的邻区可以对该上行参考信号进行测量，从而在后续的网络性能 估计中， 不仅可以考虑邻区对本小区的边缘 UE的干扰， 在下行上， 还可以 考虑到邻区对本小区的非边缘 UE (中心 UE )的干扰， 基于上行 RS来协调 小区间的发行发射功率， 有效地降低小区间的干扰。 此外， 由于考虑了非边 缘 UE受到的干扰， 可以提升小区中、 近点受弱干扰 UE的吞吐率增益， 从 而提升网络容量。
下面结合附图， 论述利用上行 RS的测量结果进行干扰协调的实施例。 图 1是本发明一个实施例的干扰协调系统的示意性框图。 图 1的干扰协 调系统 100用于对多个小区的下行发射功率进行协调，以降低小区间的干扰。 为了论述方便， 令该多个小区包括第一小区和第一小区的邻区。 当然， 第一 小区可以是该多个小区中的任一小区， 其邻区可以为一个也可以为多个。 本 发明实施例不做任何限制。
每个小区对应于一个小区管理装置，第一小区对应的小区管理装置为第 一小区管理装置， 第一小区的邻区对应的小区管理装置为第二小区管理装 置。 应注意的是， 本发明实施例， 每个小区管理装置可以对应一个或多个小 区。
以上干扰协调系统 100包括多个小区管理装置以及与多个小区管理装置 干扰协调装置 103。 每个管理单元用于管理以上多个小区中的一个小区。 为 了便于描述， 图中示出了第一小区管理装置 101 , 至少一个第一小区的邻区 分别对应的至少一个第二小区管理装置 102。
第一小区管理装置 101向至少一个第二小区管理装置 102发送上行参考 信号的配置信息， 配置信息用于指示上行参考信号所在的资源位置， 在上行 参考信号所在的资源上对第一小区内的 UE发送的上行参考信号进行测量， 得到第一测量值。
每个第二小区管理装置 102在上行参考信号所在的资源上对第一小区内 的 UE发送的上行参考信号进行测量得到第二测量值。 干扰协调装置 103根据第一测量值和至少一个第二测量值，协调第一小 区和至少一个第一小区的邻区的下行发射功率。
通过上述方案， 每个小区管理装置基于 UE发送的上行参考信号来获得 测量值， 不仅可以考虑邻区对本小区的边缘 UE的干扰， 还可以考虑到邻区 对本小区的非边缘 UE的干扰， 干扰协调装置通过基于上行参考信号获得的 测量值来协调小区间的发行发射功率， 有效地降低小区间的干扰。 此外， 由 于考虑了非边缘 UE受到的干扰， 可以提升小区中、 近点受弱干扰 UE的吞 吐率增益， 从而提升网络容量。
需要说明的是，每个小区管理装置可以分别将各自的测量值发送给干扰 协调装置 103, 也可以统一发送给某个小区管理装置（例如， 第一小区管理 装置）， 而后由该小区管理装置发送给干扰协调装置 103。 另外， 发送给干扰 协调装置 103的测量值，可以是未经过处理的值，也可以是经过预处理的值， 例如经过滤波处理后的值。
此外，每个小区管理装置可以将各自的测量值发送给第一小区管理装置 101 , 由第一小区管理装置 101处理后发送给干扰协调装置 103。 例如， 由第 一小区管理装置 101按 UE进行整理后， 即针对特定 UE的所有测量值， 可 以包括某个边缘 UE的所有测量值或某个中心 UE的所有测量值， 再发送给 干扰协调装置 103, 如此干扰协调装置 103便可以根据每个 UE的测量值， 协调下行发射功率。 当然， 也可以不经过第一小区管理装置处理， 那么干扰 协调装置 103 自己需要对测量值进行整理， 从而以某个 UE的全部测量值为 输入， 计算调制编码方案 （modulation coding scheme, MCS ), 从而确定调 度优先级， 以确定最佳发射功率。 总之， 本发明实施例不限制每个小区管理 装置上报测量值的方式， 可以各自上报给干扰协调装置， 也可以通过某个小 区管理装置上报给干扰协调装置。 另外， 也不限制上报的测量值是否经过处 理。
作为本发明的另一个实施例， 系统 100还可以进一步扩展其功能。
在可选的实施例中，每个第二小区管理装置 102可以用于向第一小区管 理装置发送第二测量值， 第一小区管理装置可以用于接收每个第二小区管理 装置 102发送的第二测量值。 进一步地， 第一小区管理装置 101将至少一个 第二测量值发送给干扰协调装置 103。 可以将接收到的第二测量值按 UE整 理后发送给干扰协调装置 103。 干扰协调装置 103进而以每个 UE的全部测 量值为输入， 计算 MCS , 从而确定调度优先级， 以确定最佳发射功率。
可选地， 上行参考信号配置信息可以包括 UE发送上行参考信号采用的 时域资源、 频域资源或时频资源。 这样， 邻区可以在相应的资源上测量该
UE发送的上行参考信号。
具体地， 第一小区管理装置上报的测量值可以示意性地如下表所示：
Figure imgf000014_0001
可选地， 第一小区管理装置 101还可以根据第一测量值和至少一个第二 测量值确定干扰信息， 干扰信息可以是 SNR ( Signal to Noise Ratio, 信噪比） 或 SIR ( Signal to Interference Ratio, 信干比）等， 将该干扰信息发送给干扰 协调装置 103。 干扰协调装置 103接收第一小区的小区管理装发送的干扰信 息， 根据干扰信息将通信系统中的多个小区分成至少一个簇， 该干扰协调装 置 103可以用于以簇为单元来协调多小区的发射功率，对包括第一小区和至 少一个第一小区的邻区的某个簇进行功率协调。
可选地， 上行 RS可以为上行 SRS ( Sounding Reference Signal, 探测参 考信号）参考信号， 也可以是其它上行 RS , 应理解， 本发明实施例对此并 不限定。 另外， 测量值可以为上行 SRS的 RSRP ( Reference Signal Receiving Power,参考信号接收功率）和 /或 RSRQ ( Reference Signal Receiving Quality, 参考信号接收质量）。 基于上行参考信号来进行测量， 稳定性和测量精度均 高于基于下行参考信号的测量，因此，协调多小区的发射功率的准确度更高， 更有效地降低小区间的干扰。
可选地， 上行参考信号配置信息可以包括 UE发送上行参考信号采用的 时域资源、 频域资源或时频资源。 这样， 邻区可以在相应的资源上测量该 UE发送的上行参考信号。
具体地， 小区级的 SRS配置信息示意性地如下列表格所示:

图 2的小区管理装置 200是上述干扰协调系统中第一小区管理装置的一 个例子， 将适当省略重复的描述。 该装置 200包括第一接口单元 201、 测量 单元 202和第二接口单元 203。
第一接口单元 201用于向至少一个第二小区管理装置发送上行参考信号 的配置信息， 配置信息用于指示上行参考信号所在的资源位置， 使得至少一 个第二小区管理装置中的每个第二小区管理装置根据配置信息，在上行参考 信号所在的资源上对第一小区内的 UE发送的上行参考信号进行测量得到第 二测量值。
测量单元 202用于根据配置信息，在上行参考信号所在的资源上对第一 小区内的 UE发送的上行参考信号进行测量， 得到第一测量值。
第二接口单元 203用于将测量单元 202测量得到的第一测量值发送给干 扰协调装置， 以便干扰协调装置根据第一测量值和至少一个第二测量值协调 第一小区和至少一个第一小区的邻区的下行发射功率。
通过上述方案， 每个小区管理装置基于 UE发送的上行参考信号来获得 测量值， 不仅可以考虑邻区对本小区的边缘 UE的干扰， 还可以考虑到邻区 对本小区的非边缘 UE的干扰， 使得干扰协调装置通过基于上行参考信号获 得的测量值来协调小区间的发行发射功率， 能够有效地降低小区间的干扰。 此外， 由于考虑了非边缘 UE受到的干扰， 可以提升小区中、 近点受弱干扰 UE的吞吐率增益， 从而提升网络容量。
需要说明的是，每个小区管理装置可以分别将各自的测量值发送给干扰 协调装置，也可以统一发送给某个小区管理装置（例如，第一小区管理装置）， 而后由该小区管理装置发送给干扰协调装置。 另外， 发送给干扰协调装置的 测量值， 可以是未经过处理的值， 也可以是经过预处理的值， 例如经过滤波 处理后的值。
此外，每个小区管理装置可以将各自的测量值发送给第一接口单元 201 , 由测量单元 202处理后发送给干扰协调装置。 例如， 由第一小区管理装置按 UE进行整理后， 再发送给干扰协调装置， 如此干扰协调装置便可以根据每 个 UE的测量值， 协调下行发射功率。 当然， 也可以不经过测量单元 202处 理， 那么干扰协调装置自己需要对测量值进行整理， 从而以某个 UE的全部 测量值为输入， 计算 MCS, 从而确定调度优先级， 以确定最佳发射功率。 总之， 本发明实施例不限制每个小区管理装置上报测量值的方式， 可以各自 上报给干扰协调装置， 也可以通过某个小区管理装置上报给干扰协调装置。 另外， 也不限制上报的测量值是否经过处理。
可选地， 第一接口单元 201还可以用于接收每个第二小区管理装置发送 的第二测量值。 进一步地， 第二接口单元还用于将第一接口单元 201接收的 至少一个第二测量值发送给干扰协调装置。该第一小区管理装置还包括干扰 确定单元 204, 干扰确定单元 204用于根据第一测量值和至少一个第二测量 值， 确定干扰信息， 干扰信息可以是 SNR或 SIR等。 第二接口单元 203还 可以用于将干扰信息发送给干扰协调装置， 以便干扰协调装置根据干扰信息 将通信系统中的多个小区分成至少一个簇， 第一小区和至少一个第一小区的 邻区属于同一个簇。
可选地， 上行 RS可以为上行 SRS参考信号， 也可以是其它上行 RS, 应理解，本发明实施例对此并不限定。另外，测量值可以为上行 SRS的 RSRP 和 /或 RSRQ。基于上行参考信号来进行测量， 稳定性和测量精度均高于基于 下行参考信号的测量， 因此， 协调多小区的发射功率的准确度更高， 更有效 地降低小区间的干扰。
可选地， 上行参考信号配置信息可以包括 UE发送上行参考信号采用的 时域资源、 频域资源或时频资源。 这样， 邻区可以在相应的资源上测量该 UE发送的上行参考信号。

需要说明的是，每个小区管理装置可以分别将各自的测量值发送给干扰 协调装置，也可以统一发送给某个小区管理装置（例如，第一小区管理装置）， 而后由该小区管理装置发送给干扰协调装置。 另外， 发送给干扰协调装置的 测量值， 可以是未经过处理的值， 也可以是经过预处理的值， 例如经过滤波 处理后的值。

本发明实施例的技术方案可以应用于不同的场景， 下面示例性地描述了 本发明实施例可应用的场景图和系统的部署。
可选地， 当通信网络为分布式基站组网模式且部署协调器， 通信网络的 各个基站与协调器互连， 第一小区管理装置和至少一个第二小区管理装置分 别位于通信网络的各个基站、 干扰协调装置位于协调器。 可选地， 基站之间 通过 x2接口相连接， 即通过 x2接口交互信息。 或者当通信网络的各个基站 的基带处理单元 BBU集中放置（Cloud BB ), 第一小区管理装置和至少一个 第二小区管理装置分别位于集中放置的各个 BBU, 干扰协调装置位于集中 放置的 BBU中的某个 BBU (第一 BBU )。 可选地， BBU之间通过互联接口 相连接。
具体地，如图 5所示的网络场景，分布式基站通过 IP回程线路（ Backhaul ) 与 ECO互联， 每个小区的小区管理装置位于与该小区对应的基站中。 ECO 中部署干扰协调装置， 可选地， 在 ECO 中可以部署分簇单元。 在该场景下 干扰协调装置协调的每个小区簇中多个小区间的下行发射功率 （也称为 CSPC调度），两个小区簇分别是小区簇 1的各个小区和小区簇 2中的部分小 区。 在另一种 Cloud BB的组网场景下， 将网络中基站的 BBU集中放置与 USU ( Universal Switching Unit, 通用交换单元 ) 互联， 并通过光纤与 RRU 连接。 每个小区的小区管理装置位于与该小区对应的 BBU。 在该 Cloud BB 中选择一个 BBU部署干扰协调装置， 可选地， 在该 BBU中可以部署分簇单 元。 在 Cloud BB的场景也示出两个小区簇， 分别是小区簇 3和小区簇 2的 部分小区。 也就是说， 小区簇 2中的各个小区可以由 ECO和 BBU共同进行 CSPC调度。 ECO可实现大范围（大于一定覆盖面积或小区数量）、慢速 (如 20ms-40ms ) 集中调度， Cloud BB可实现小范围、 快速 (如 lms-5ms )集中 调度。 本发明实施例描述的第一小区和第一小区的邻区都属于同一个簇。
应注意的是， 图 5的场景图仅仅是示意性的， 本发明实施例对小区分簇 的数目， 各个簇包括的小区数目、 基站的数目、 一个基站下的小区数目以及 BBU 的数目并不限定， 基站的类型可以是宏基站、 微基站、 微微基站、 毫 微微基站或家庭基站等， 本发明实施例对此也不作限定。
示例性地， 在协调器进行 CSPC调度的情况下， 干扰协调系统的示意图 如图 6所示， 在该图中， ECO包括干扰协调装置。 各个分布式基站部署有小 区管理装置。 需要说明的是， 不同小区的服务基站可以相同或不同。 还需要 说明的是图中的小区管理装置部署在主控板， 应理解， 小区管理装置中各个 单元实现的功能仅仅为一种逻辑功能划分， 实际实现时可以结合或者集成到 一个物理实体， 也可以是物理上分开的， 分布在不同的网络设备或同一网络 设备的不同位置中。 如小区管理装置可以部署在基站的基带板， 或者小区管 理装置包括的实现不同功能的单元分布在基站的不同位置。
为了方便理解， 这里将以不同小区对应的服务基站不同为例进行说明。 假设某个 UE的服务小区为第一小区， 第一小区的服务基站为基站 1 , 第一 小区具有（M-1 )个相邻小区， M为大于或等于 2的整数， （M-1 )个相邻小 区的服务基站分别是基站 2,基站 3, ... ... ,基站 M。 该 UE可以是边缘 UE, 也可以是非边缘 UE。 上行 RS以上行 SRS为例， 本发明对此并不限定。
第一小区管理装置 601-1可以用于测量本小区某个 UE的上行 RS获得 第一测量值，并通过 x2接口分别向与该（M-1 )个相邻小区——对应的（M-1 ) 个第二小区管理装置发送 UE的上行 SRS配置信息。 可选地， 该上行 SRS 配置信息可以包括小区级的 SRS配置信息和 UE级的 SRS配置信息， 小区 级的 SRS配置信息表示该第一小区的所有 UE发送上行 RS可采用的资源， 用户级的 SRS配置信息表示某个 UE发送上行 RS采用的资源。 具体地， 可 以是时域资源或频域资源或者时频资源。各个第二小区管理装置用于根据上 行 SRS配置信息在相应的资源上测量该 UE发送的上行 SRS获得第二测量 值（如上行 SRS的 RSRP ), 可选地， 可以通过 x2接口发送给第一小区管理 装置 601-1 , 或者直接发送给干扰协调装置。 第一小区管理装置 601-1还可 以用于根据第一测量值和（M-1 ) 个第二测量值确定干扰信息， 将干扰信息 发送给干扰协调装置 602。 干扰协调装置 602用于根据第一测量值和 M-1个 第二测量值确定这 M个小区的下行发射功率， 还可以用于根据干扰信息对 通信系统中的多个小区进行分簇。
示例性地，在 BBU进行 CSPC调度的情况下，如上述 Cloud BB的场景， 干扰协调系统的示意图如图 7所示， 在该图中， 某个 BBU, 如 BBU 1的基 带板， 可以是普通基带本也可以是专用基带板， 部署干扰协调装置 702, 各 个 BBU均部署有小区管理装置。 BBU之间可以通过互联接口进行信息交互。 可选地， 干扰协调装置 702可以均位于第一 BBU的普通基带板或专用基带 板， 小区管理装置可以部署在 BBU的主控板或普通基带板或专用基带板。
需要说明的是， 不同小区的服务基站可以相同或不同， 即不同小区的 BBU 可以相同或不同。 应理解， 小区管理装置中各个单元实现的功能仅仅 为一种逻辑功能划分， 实际实现时可以结合或者集成到一个物理实体， 也可 以是物理上分开的， 分布在不同的网络设备或同一网络设备的不同位置中。 例如，可以由基站或 BBU的主控板实现上行 RS配置信息的交互， 由基站或 BBU的基带板实现对 UE的上行 RS的测量。 应理解， 本发明实施例对此并 不限定。 类似地， 具体的实施例可以参考图 6的例子， 此处不再赘述。
需要说明的是， 以上实施例中的接口单元（包括第一接口单元和第二接 口）可以为接口电路。 测量单元可以为单独设立的处理器， 也可以集成在基 站的某一个处理器中实现， 此外， 也可以以程序代码的形式存储于基站的存 储器中， 由基站的某一个处理器调用并执行以上跟踪任务建立单元的功能。 干扰确定单元、 获取单元， 分簇单元和协调单元的实现同选择单元。 这里所 述的处理器可以是一个中央处理器（Central Processing Unit, CPU ), 或者是 特定集成电路 ( Application Specific Integrated Circuit, ASIC ), 或者是被配 置成实施本发明实施例的一个或多个集成电路。

需要说明的是，每个小区管理装置可以分别将各自的测量值发送给干扰 协调装置，也可以统一发送给某个小区管理装置（例如，第一小区管理装置）， 而后由该小区管理装置发送给干扰协调装置。 另外， 发送给干扰协调装置的 测量值， 可以是未经过处理的值， 也可以是经过预处理的值， 例如经过滤波 处理后的值。
此外， 每个小区管理装置可以将各自的测量值发送给接口电路 803, 由 处理器 801处理后发送给干扰协调装置。 例如， 由第一小区管理装置按 UE 进行整理后， 再发送给干扰协调装置， 如此干扰协调装置便可以根据每个 UE的测量值， 协调下行发射功率。 当然， 也可以不经过处理器 801处理， 那么干扰协调装置自己需要对测量值进行整理， 从而以某个 UE的全部测量 值为输入， 计算 MCS, 从而确定调度优先级， 以确定最佳发射功率。 总之， 本发明实施例不限制每个小区管理装置上报测量值的方式， 可以各自上报给 干扰协调装置， 也可以通过某个小区管理装置上报给干扰协调装置。 另外， 也不限制上报的测量值是否经过处理。
可选地，接口电路 803还可以用于接收每个第二小区管理装置发送的第 二测量值。 进一步地， 第二接口单元还用于将接口电路 803接收的至少一个 第二测量值发送给干扰协调装置。处理器 801还可以用于根据第一测量值和 至少一个第二测量值， 确定干扰信息， 干扰信息可以是 SNR或 SIR等。 接 口电路 803还可以用于将干扰信息发送给干扰协调装置， 以便干扰协调装置 才艮据干 4尤信息将通信系统中的多个小区分成至少一个簇， 第一小区和至少一 个第一小区的邻区属于同一个簇。
