Description

干扰控制方法和设备 本申请要求于 2011 年 9 月 26 日提交中国专利局、 申请号为 201110287939.7、 发明名称为 "干扰控制方法和设备" 的中国专利申请的优 先权, 其全部内容通过引用结合在本申请中。 技术领域
本发明实施例涉及无线通信领域, 更具体地说, 涉及无线通信系统中 的干扰控制方法和设备。 发明背景
无线通信系统可以提供话音、 数据等无线业务。 通常的无线通信系统 是一个多址接入的无线系统。 在一个无线通信系统中, 基站在下行链路上 给用户设备发射数据和 /或控制信息, 并在上行链路上接收用户设备的数据 和 /或控制信息。 类似的, 用户设备 ( User Equipment , 简称 UE )在上行链 路上为基站传输数据和 /或控制信息, 并在下行链路上接收基站发射的数据 和 /或控制信息。 以下将以长期演进(Long Term Evolution, 简称 LTE )和 / 或高级长期演进 ( Long Term Evolution Advanced, 简称 LTE-A )无线通信 系统为例, 阐述本发明的技术背景。
为了满足或提升 LTE-A的性能需求,在同构网络 (homogeneous network) 内部署不同类型或不同制式的基站 (如低发射功率的基站或发射 /接收节 点,, 以增强网络的覆盖和性能, 这样的网络结构被称之为异构网络 (Heterogeneous network)。 以下以异构网络中部署了大发射功率基站如宏基 站和与宏基站( MeNB )釆用同一种制式但是不同类型的低发射功率基站 (简 称低功率基站, lower power node, LPN)为例, 进一步阐述本发明的技术背 景。
为了提高系统的频谱利用效率, 可使 LPN可配置的上行和 /或下行频 谱资源与 MeNB可配置的上行和 /或下行频语资源进行完全或部分的频语复 用。 此时 , 由于 LPN配置了和 MeNB相同或部分相同的频语资源 , 因此 LPN (或 LPN服务的 UE)和 MeNB (或 MeNB服务的 UE)的下行 (或上行)信道 传输之间会产生同道 (或同频)干扰。 干扰会影响 LPN及 MeNB下行信道传 输及上行信道 (信道包括控制信道及数据信道)检测的可靠性。
目前 LTE-A标准中釆用时分复用 (Time Division Multiplexing, 简称 TDM) 'J、区间干扰协调 (Inter Cell Interference Coordination , 简称 ICIC)的方 法处理异构网络场景下小区间的干扰。 干扰基站将某些子帧设置为低传输 功率或者不进行业务传输 (即业务的传输功率为零),上述子帧可以称之为近 似空子帧 (Almost Blank Subframe, 简称 ABS)。 被干扰基站将受到干扰基站 强干扰的 UE调度在该干扰基站配置的 ABS子帧对应的子帧上进行业务传 输, 从而保证被干扰基站受害 UE 的传输性能。 但为了后向兼容性, ABS 子帧依然会发送小区参考信令( Cell Reference Signaling, 简称 CRS )和其 他必要的控制信息, 如同步信令和系统消息。 在小区的边缘受到强干扰的 情况下,邻区的 ABS子帧的 CRS信令依然会对受干扰小区的 UE对下行的 物理下行控制信道(Physical Downlink Control Channel, 简称 PDCCH )和 物理下行共享信道( Physical Downlink Share Channel, 简称 PDSCH )上的 信令 /数据的解码造成很大的威胁。 所以, 需要解决这种干扰问题的技术方 案。 发明内容

130: 根据所述干扰小区的物理小区标识(Physical Cell Indicator, 简称 PCI )和所述天线端口数,获取所述干扰小区的小区参考信令( Cell Reference Signaling, 简称 CRS )位置;
140: 根据所述 CRS位置信息, 进行干扰控制, 如在所述 CRS位置获 取的信号中减去从所述干扰小区接收的信号, 或者, 丟弃在所述 CRS位置 获取的信号。
根据本发明实施例, UE可以对服务小区的无线信号进行测量, 并由此 监测服务小区的无线资源信号的质量。 例如, UE 可以通过信道质量指示 ( Channel Quality Indictor, 简称 CQI ) 测量来获得信号与干扰加噪声比 ( Signal to Interference plus Noise Ratio, 简称 SINR )值, 或者 UE可以通 过无线资源管理(Radio Resources Management, 简称 RRM )测量来获得 RSRQ值。 UE可以将 SINR值或 RSRQ值与服务基站发送给 UE的门限 Thic 进行比较。如果 SINR或者 RSRQ低于该门限 Thic, 则表示 UE受到相邻小 区的干扰导致信号质量变差, 需要实施干扰控制。 如果 SINR或者 RSRQ 高于该门限 Thic, 则表示 UE受到的相邻小区的干扰并不严重, 可以不进 行干扰控制。
根据本发明实施例, 在步骤 110 中执行邻区测量时, 可以选择被测邻 区中 RSRP/RSRQ较之服务小区的 RSRP/RSRQ大的量等于或超过门限 Thag (例如, 6dB )的邻区作为干扰小区。 这里的干扰小区表示对服务小区内的 UE信号干扰较强的邻区。 干扰小区的数量可以选择一个或者多个。 例如, 根据邻区的 RSRP/RSRQ 高低排序, 选择 RSRP/RSRQ 比服务小区的 RSRP/RSRQ大的量超过 Thag的几个邻区作为干扰小区。
根据本发明实施例, 在步骤 130 中根据所述干扰小区的物理小区标识 PCI和所述天线端口数, 获取所述干扰小区的小区参考信令 CRS位置, 需 要对邻区进行同步, 从而获得邻区的 PCI, 同时也得到了干扰小区的 PCI。 在获取了干扰小区的 CRS位置之后, 可以在步骤 140中对从干扰小区接收 的信号进行干扰排除处理。
根据本发明实施例, 在步骤 140中, 当 UE接收到干扰小区的 CRS位 置的无线资源上的数据或信令时, UE将实施干扰协调。例如, UE将该 CRS 位置处接收到的发自所述干扰小区的信号解析出来, 并将其从该 CRS位置 处接收到的全部信号 (包括发自服务小区的信号以及所有邻区的信号) 中 剔除出去, 或者在干扰小区的干扰非常强烈的时候, UE可以将该 CRS位 置处接收到的全部信号丟弃。
以上所述本发明实施例中, 干扰协调中辨别干扰小区, 即强干扰邻区 的工作主要由 UE侧来完成,在优选的实施方式中,基站可以预先通过专用 的消息或者其他通知信令将上述的门限 Thag和 Thic发送给 UE, 用于 UE 进行干扰协调。 具体方式通过系统广播消息, 和 /或 RRC 专用信令, 或 MAC(Medium Access Control 媒体接 入控 制 ) 控 制 信 令 , 或 PDCCH(Physical Downlink Control Channel控制信令)。
根据本发明其他实施例, 干扰协调中辨别干扰小区的工作也可以主要 由基站侧来完成。
图 2是本发明另一种实施例的干扰控制方法 200的流程图, 在这种实 施例中, 首先由基站侧辨别出干扰小区, 然后通知 UE进行干扰协调。 如图 2所示, 干扰控制方法 200包括:
210: 基站确定干扰小区, 并获取干扰小区的 PCI和天线端口数。
根据本发明实施例, 基站可以釆用多种方式来确定干扰小区。 一种确 定干扰小区的方式为:基站接收 UE发送的测量报告,其中所述测量报告包 括服务小区的 RSRP值以及邻区的 RSRP值;基站确定 RSRP值大于所述服 务小区的 RSRP值的至少一个邻区为干扰小区。 如上所述, 基站也可以通 过 RSRQ值来确定干扰小区。 类似于上述实施例, 也可以通过 UE发送的 测量报告中的服务小区和邻区 RSRQ值来确定干扰小区。
另一种确定干扰小区的方式为:基站通过操作管理维护实体( Operation, Administration and Maintenance, 简称 OAM )配置的服务小区和其它邻区的 侵害和受害的关系 (受到下行强干扰的小区是受害小区, 干扰其它小区的 小区是侵害小区)确定至少一个侵害邻区为干扰小区。
另一种确定干扰小区的方式为: 基站通过接收到的负荷指示 (Load Indication )获取的相关窄带发射功率 ( Relative Narrowband TX Power, 简 称 RNTP )超过门限获知邻区对本服务小区的 UE有下行干扰, 从而确定干 扰小区。
220: 向 UE发送干扰控制消息, 其中所述干扰控制消息包括所述干扰 小区的 PCI和天线端口数, 以便所述 UE根据所述干扰小区的 PCI和所述 天线端口数, 获取所述干扰小区的 CRS位置, 根据所述 CRS位置信息, 进 行干扰控制, 如在所述 CRS位置获取的信号中减去从所述干扰小区接收的 信号, 或者, 丟弃在所述 CRS位置获取的信号。 根据本发明这种实施例 ,在步骤 210中通过 RSRP/RSRQ值或者 RNTP 值确定干扰小区时,基站可以将邻区的 RSRP/RSRQ或者 RNTP值按照高低 进行排序, 从而确定一个或者多个干扰小区。 与上述实施例的干扰控制方 法 100中相同,基站可以选择被测邻区中 RSRP/RSRQ或者 RNTP值较之服 务小区的 RSRP/RSRQ或者 RNTP值大的量等于或超过门限 Thag (例如, 6dB ) 的邻区作为干扰小区。
在基站辨别出干扰小区之后,则可以在步骤 220中将干扰小区通知 UE, 以便 UE进行干扰协调。具体的干扰协调机制类似于上述干扰控制方法 100 中的步骤 140, 即当 UE接收到干扰小区的 CRS位置的无线资源上的数据 或信令时, UE将实施干扰协调。 例如, UE将该 CRS位置处接收到的发自 所述干扰小区的信号解析出来, 并将其从该 CRS位置处接收到的全部信号 (包括发自服务小区的信号以及所有邻区的信号) 中剔除出去, 或者在干 扰小区的干扰非常强烈的时候, UE可以将该 CRS位置处接收到的全部信 号丟弃。
在本实施例中, 如果通过 RSRP/RSRQ值来确定干扰小区, 则从 UE侧 来看, UE主要完成的工作为:
UE 向基站发送测量报告, 其中所述测量报告包括服务小区的 RSRP/RSRQ值以及邻区的 RSRP/RSRQ值,以使所述基站确定 RSRP/RSRQ 值大于所述服务小区的 RSRP/RSRQ值的至少一个邻区为干扰小区,并使得 所述基站获取所述干扰小区的 PCI和天线端口数;
UE接收所述基站发送的干扰控制消息, 其中所述干扰控制消息包括所 述干扰小区的 PCI和天线端口数;
UE根据所述干扰小区的 PCI和所述天线端口数,获取所述干扰小区的 CRS位置;
UE根据所述 CRS位置信息, 进行干扰控制, 如在所述 CRS位置获取 的信号中减去从所述干扰小区接收的信号, 或者, 丟弃在所述 CRS位置获 取的信号。
根据本发明其他实施例, 干扰协调可以由基站和 UE协同实现。
图 3是根据本发明另一种示例的干扰控制方法 300的流程图, 在这种 实施例中, 首先由 UE侧确定干扰小区, 然后基站侧获取干扰小区的 PCI 和天线端口数, 接着由 UE侧进行干扰协调。 如图 3所示, 干扰控制方法 300包括:
310: 执行邻区测量, 选择被测邻区中信号发送强度大于服务小区的信 号发送强度的至少一个邻区作为干扰小区;
320: 向基站发送请求消息, 用于获取所述干扰小区的天线端口数, 其 中所述请求消息携带所述干扰小区的 PCI;
330: 接收基站发送的干扰小区针对所述请求消息的响应消息, 其中所 述响应消息携带所述干扰小区的 PCI和所述干扰小区的天线端口数;
340: 根据所述干扰小区的 PCI和所述干扰小区的天线端口数, 获取所 述干扰小区的 CRS位置;
350: 根据所述 CRS位置信息, 进行干扰控制, 如在所述 CRS位置获 取的信号中减去从所述干扰小区接收的信号, 或者, 丟弃在所述 CRS位置 获取的信号。
与图 1所示实施例相同,所述信号发送强度可以利用 RSRP或者 RSRQ 值来表示。
与图 1所述实施例相同, 根据图 3所示的本发明实施例, UE可以对服 务小区的无线信号进行测量, 并由此监测服务小区的无线资源信号的质量。 例如, UE可以通过 CQI测量来获得 SINR值, 或者 UE可以通过 RRM测 量来获得 RSRQ值。 UE可以将 SINR值或 RSRQ值与服务基站发送给 UE 的门限 Thic进行比较。如果 SINR或者 RSRQ低于该门限 Thic,则表示 UE 受到相邻小区的干扰导致信号质量变差, 需要实施干扰控制。如果 SINR或 者 RSRQ高于该门限 Thic, 则表示 UE受到的相邻小区的干扰并不严重, 可以不进行干扰控制。
根据本发明实施例, 在步骤 310 中执行邻区测量时, 可以选择被测邻 区中 RSRP/RSRQ较之服务小区的 RSRP/RSRQ大的量等于或超过门限 Thag (例如, 6dB )的邻区作为干扰小区。 这里的干扰小区表示对服务小区内的 UE信号干扰较强的邻区。 干扰小区的数量可以选择一个或者多个。 例如, 根据邻区的 RSRP/RSRQ 高低排序, 选择 RSRP/RSRQ 比服务小区的 RSRP/RSRQ大的量超过 Thag的几个邻区作为干扰小区。
与图 1所示实施例不同的是, 根据图 3所示实施例, 在步骤 320中, UE根据所述干扰小区的 PCI向基站发送请求消息, 以获取所述干扰小区的 天线端口数。 然后在步骤 330中, UE接收基站发送的针对所述请求消息的 响应消息, 将所述干扰小区的天线端口数发送给 UE。 在获取了干扰小区的 CRS位置之后, UE可以在步骤 340中根据所述干扰小区的 PCI以及天线端 口数, 获取所述干扰小区的 CRS位置。 然后在步骤 350中对从干扰小区接 收的信号进行干扰排除处理。
根据本发明实施例, 在步骤 350中, 当 UE接收到干扰小区的 CRS位 置的无线资源上的数据或信令时, UE将实施干扰协调。例如, UE将该 CRS 位置处接收到的发自所述干扰小区的信号解析出来, 并将其从该 CRS位置 处接收到的全部信号 (包括发自服务小区的信号以及所有邻区的信号) 中 剔除出去, 或者在干扰小区的干扰非常强烈的时候, UE可以将该 CRS位 置处接收到的全部信号丟弃。
在图 3 所示本发明实施例中, 干扰协调中辨别干扰小区, 即强干扰邻 区的工作由 UE侧和基站侧协同来完成,在优选的实施方式中,基站可以预 先通过专用的消息或者其他通知信令将上述的门限 Thag和 Thic发送给 UE, 用于 UE进行干扰协调。具体方式通过系统广播消息,和 /或 RRC专用信令, 或 MAC(Medium Access Control媒体接 入控 制 ) 控 制 信 令 , 或 PDCCH(Physical Downlink Control Channel控制信令)。 UE受到来自邻区的信号的干扰, 主要是由于服务小区的 CRS位置与 邻区的 CRS位置发生冲突所导致。在存在信道状态信息参考信令( Channel Status Information Reference Signaling, 简称 CSI-RS ) 的情况下, 服务小区 的 CSI-RS配置信息与邻区的 CSI-RS配置信息发生冲突也将对服务小区中 的 UE产生干扰。 因此, 根据本发明另一种实施例, 可以考虑服务小区内的 基站 eNBl 与邻区内的基站 eNB2之间进行协调, 避免 eNBl和 eNB2的 CRS/CSI-RS发生冲突, 并由此减弱甚至消除对服务小区内的 UE的干扰。
图 4是本发明另一种实施例的干扰控制方法 400的流程图。 如图 4所 述, 干扰控制方法 400包括:
410: 第一基站 eNBl向第二基站 eNB2发送 X2建立请求消息,其中所 述 X2建立请求消息中携带第一基站 eNBl的服务小区的 PCI和天线端口数, 和 /或, 携带所述第一基站的 CSI-RS信息,
以使所述第二基站 eNB2根据所述第一基站 eNBl 的所述服务小区的 PCI 和天线端口数获取所述第一基站的 CRS 位置, 并判断所述第二基站 eNB2下是否存在服务小区的 CRS位置与所述第一基站 eNBl的 CRS位置 冲突,和 /或根据所述第一基站 eNBl的 CSI-RS判断是否所述第二基站 eNB2 的 CSI-RS与所述第一基站 eNBl的 CSI-RS冲突;
420: 在所述判断结果为存在 CRS位置冲突和 /或所述 CSI-RS冲突时, 所述第一基站 eNBl 改变其服务小区的 PCI和 /或改变所述第一基站 eNBl 的 CSI-RS。
eNBl改变其服务小区的 PCI可以使得其 CRS位置发生变化, 因此不 再与 eNB2的 CRS位置发生冲突。
根据本发明实施例, eNBl改变其 PCI和 /或改变其 CSI-RS配置信息可 以通过 eNBl与 eNB2进行协商来实现。 具体实现过程为:
第一基站 eNBl接收所述第二基站 eNB2发送的 X2建立响应消息, 其 中所述 X2建立响应消息中携带请求所述第一基站 eNBl改变其服务小区的 PCI和 /或改变所述第一基站的 CSI-RS的请求信息;
第一基站 eNBl根据所述改变服务小区的 PCI和 /或改变所述第一基站 eNBl的 CSI-RS的请求信息, 改变第一基站 eNBl的服务小区的 PCI和 /或 改变所述第一基站的 CSI-RS;
第一基站 eNBl向第二基站 eNB2发送配置更新消息,其中所述配置更 新消息携带改变后的所述第一基站 eNBl的服务小区的 PCI和 /或改变后的 所述第一基站 eNB2的 CSI-RS。
根据本发明另一种实施例, eNBl也可以根据 eNB2的请求,偏移 eNBl 的 CRS和 /或 CSI-RS的位置。 具体实现过程为:
第一基站 eNBl接收第二基站 eNB2发送的时间偏移消息,其中所述时 间偏移消息携带时间符号偏移值或子帧偏移值;
第一基站 eNBl根据所述时间符号偏移消息中的所述时间符号偏移值, 偏移所述第一基站的 CRS和 /或偏移所述第一基站 eNBl的 CSI-RS。
根据本发明另一种实施例, eNB2也可以改变自己的服务小区的 PCI和 /或 CSI-RS配置, 以避免与 eNBl的 CRS和 /或 CSI-RS发生碰撞。 从 eNB2 侧来观察, eNB2完成的主要工作为:
第二基站 eNB2接收第一基站 eNBl发送 X2建立请求消息, 其中所述 X2建立请求消息中携带第一基站 eNBl的服务小区的 PCI和天线端口数, 和 /或, 携带所述第一基站 eNBl的 CSI-RS信息;
第二基站 eNB2根据第一基站 eNBl的所述服务小区的 PCI和天线端口 数获取第一基站 eNBl的 CRS位置, 并判断第二基站 eNB2下是否存在服 务小区的 CRS位置与第一基站 eNBl的 CRS位置冲突,和 /或根据所述第一 基站 eNBl的 CSI-RS判断是否所述第二基站 eNB2的 CSI-RS与所述第一基 站 eNBl的 CSI-RS冲突;
在所述判断结果为存在 CRS位置冲突和 /或所述 CSI-RS冲突时, 所述 第二基站 eNB2改变其服务小区的 PCI和 /或改变所述第二基站的 CSI-RS。 根据本发明另一种实施例, 在存在 CRS位置冲突和 /或所述 CSI-RS位 置冲突时,第二基站 eNB2也可以自己偏移其服务小区的 CRS和 /或 CSI-RS 配置, 所述偏移是时间符号偏移或子帧偏移, 并通知第一基站 eNBl , 以避 免 CRS/CSI-RS冲突。
