为使本发明实施例的上述目的、 特征和优点能够更加明显易懂, 下 面结合附图和具体实施方式对本发明实施例作进一步详细的说明。
值得说明的是, 在本发明实施例中, 主要针对在 LTE系统中不同基 站(eNodeB )之间的干 ·ί尤, 由于基站和小区存在对应的关系, 所以, 不 同基站之间的干扰也可以理解为属于不同基站的小区之间发生的干扰, 通常包括下行干扰和 /或上行干扰。 图 2为本发明实施例下行干扰协调方法流程示意图, 如图 2所示, 本发明一种干扰协调方法, 包括以下步骤:
步骤 210, 第一基站确定与相邻基站发生了干扰;
假设基站 Α和基站 B为相邻基站, 基站 A与基站 B发生的干扰, 可能是上行干扰或者下行干扰, 或者同时发生了上行和下行干扰。
假设基站 A中的小区受到基站 B的小区中 UE的上行干扰, 或者基 站 A的小区中的 UE受到基站 B的小区的下行干扰,则基站 A确定与基 站 B发生了干扰。
步骤 220, 第一基站向相邻基站发送携带干扰小区标识及针对干扰 小区的干扰协调清求信息( Request For Interfere Correspond )的第一消息; 在本步骤中, 第一基站向相邻基站发送第一消息, 该第一消息携带 干扰小区标识及针对干扰小区的干扰协调请求信息。
为方便说明, 在本实施例中, 当基站 A受到基站 B的上行干扰时, 干扰小区为基站 B中对基站 A产生干扰的 UE所在的小区; 当基站 A受 到基站 B的下行干扰时, 干扰小区为基站 B中对基站 A的小区中的 UE 产生干扰的小区。 基站 A向基站 B发送第一消息, 在该第一消息中携带 干扰小区的标识, 以及针对该干扰小区的干扰协调请求信息。
此外, 该第一消息中还可以携带基站 A中被干扰的 UE所在的小区 或者被干扰的小区的小区信息, 如小区标识、 小区的频带划分方式及计 算干扰所需要的参数。
步骤 230, 相邻基站根据干扰小区标识及针对干扰小区的干扰协调 请求信息进行干扰协调;
相邻基站在收到第一消息后, 根据第一消息中的干扰小区标识以及 针对干扰小区的干扰协调请求进行干扰协调。 相邻基站可以通过调整干 扰小区的高功率频带, 与基站 A进行干扰协调。
在本实施例中, 向相邻基站发送的消息中携带干扰小区的标识, 并 携带针对该干扰小区的干扰协调请求, 相邻基站在收到该消息后, 根据 所接收的消息进行干扰协调,提高干扰协调的效率, 增加通信的稳定性。 当第一基站与相邻基站之间发生干扰为第一基站的小区中的 UE受 到属于相邻基站的小区的下行干扰时, 本发明另一实施例详细说明了该 干扰协调方法。 图 3为本发明另一实施例的干扰协调方法流程示意图, 如图 3所示, 本发明另一实施例的干扰协调方法包括以下步骤: 步骤 310, 第一基站确定与相邻基站发生了干扰;
第一基站确定属于第一基站的小区中的用户设备 UE受到属于相邻 基站的干扰小区的干扰;
假设基站 A的相邻基站有基站 B、 基站 C, 基站 A中有小区 Al、 小区 A2及小区 A3, 基站 B中有小区 Bl、 小区 B2及小区 B3, 基站 C 中有小区 Cl、 小区 C2及小区 C3, 小区 Al的邻区有小区 Bl、 小区 B2 及小区 Cl。 其中, 小区 A1中的 UE测量到小区 B1和小区 Cl, 通过该 UE 上报给小区 A1 的参考信号接收功率 (Reference Signal Receiving Power, 简称 RSRP)能够计算出邻区 B1及邻区 C1对小区 A1干扰的大 小, 当干扰超过预设的值, 则基站 A可以确定小区 A1 中的 UE受到基 站 B中小区 B1和基站 C中小区 C1的干扰。
步骤 320, 第一基站向相邻基站发送携带干扰小区标识及针对干扰 小区的干扰协调请求信息的第一消息;
在本步骤中, 第一基站向相邻基站发送第一消息, 并在该第一消息 中携带干扰小区标识及针对该干扰小区的干扰协调请求信息, 该干扰 'J、 区是干扰该 UE的相邻基站的小区, 该干扰协调请求信息指示该邻基站 进行干扰小区和该被干扰的 UE所处的小区之间的干扰协调。
由于基站 A的小区 A1的 UE受到小区 B1和小区 C1的干 ·ί尤, 基站 Α向基站 Β和基站 C发送第一消息, 希望基站 B中的小区 B1与基站 A 中的小区 A1进行干扰协调, 以及基站 C中的小区 C1与基站 A中的小 区 A1进行干扰协调。
基站 A发送的第一消息中可以包括小区 B1的标识, 以及针对该小 区 B1的干扰协调请求信息, 指示小区 B1与小区 A1进行干扰协调。 基 站 A发送的第一消息中还可以包括小区 C1的标识, 以及针对该小区 C1 的干扰协调请求信息, 指示小区 C1与小区 A1进行干扰协调。 该第一消息中还可以携带小区 Al的信息,如小区 A1的标识频带划 分方式及计算干扰所需要的参数。
步骤 330, 相邻基站判断自身的小区中是否有干扰小区标识所对应 的干扰小区, 若判断结果为是, 则执行步骤 340, 若判断结果为否, 则 执行步骤 350;
在本步骤中, 相邻基站判断自身的小区中是否有干扰小区标识所对 应的干扰小区, 干扰小区指的是对第一基站的小区中的 UE产生了下行 干扰的小区。 该相邻基站通过判断属于自身的小区中是否有第一消息中 所携带的干扰小区标识对应的小区来判断自身的小区中是否有干扰小 区, 若判断结果为是, 说明该相邻基站自身的小区中有干扰小区, 则执 行步骤 340, 若判断结果为否, 说明该相邻基站自身的小区中没有干扰 小区, 则执行步骤 350。
基站 B收到基站 A发送的第一消息后,识别该第一消息中携带的小 区标识, 并将第一消息中的小区标识与基站 B 自身中包含的小区的标识 相比较, 判断基站 B中是否有与该第一消息中小区标识相一致的小区。 基站 B判断该第一消息中有小区 Bl, 而基站 B中有小区 Bl, 则基站 B 判断自身的小区中有干扰小区。 同样, 基站 C收到基站 A发送的第一消 息中携带小区 C1 的标识, 基站 C判断自身的小区中有干扰小区, 执行 步骤 340。
假设基站 D也是基站 A的相邻基站, 基站 A还向基站 D发送了该 第一消息, 基站 D收到第一消息之后识别该第一消息中包含小区 B1和 小区 C1的标识, 而属于基站 D的小区中没有这两个小区, 因此基站 D 判断自身的小区中没有干扰小区, 执行步骤 350。
步骤 340, 相邻基站根据干扰协调请求消息, 进行干扰小区和被干 扰的 UE所在的小区之间的下行干扰协调;
若判断结果是属于相邻基站的小区中有干扰小区, 相邻基站根据干 扰协调指示在干扰小区与受到干扰的 UE的小区进行干扰协调, 即相邻 基站根据干扰协调请求进行干扰小区和被干扰小区之间的下行干扰协 调, 被干扰小区是指受到干扰的 UE所在的小区。
以基站 B为例, 基站 B根据干扰协调指示, 在小区 B 1和小区 A1 之间进行干扰协调。 由于在现有技术中基站之间发送的负载消息中的相 对窄带传输功率 ( Relative Narrowband Tx Power , 简称 RNTP )信元中 包含被干扰的 UE所在小区 A1的频带划分方式,基站 B根据小区 A1该 频带划分方式, 结合小区 B1 的频带划分方式, 使得小区 B1和小区 A1 错开高功率频带, 从而达到下行干扰协调的目的。
步骤 350, 相邻基站存储第一消息中的信息, 或不进行操作, 或继 续等待后续消息;
判断结果是属于相邻基站的小区中没有干扰小区, 相邻基站存储第 一消息中的信息, 或者根据干扰协调请求消息不进行干扰协调, 或者继 续等待后续消息。
以基站 D为例, 基站 D判断基站 D中没有干扰小区, 则基站 D进行 以下操作之一或组合: 存储该第一消息中的信息, 或者, 依据所接收到 的第一消息中的干扰协调请求不进行干扰协调,或者继续等待后续消息。
在本实施例中, 基站向相邻基站发送的第一消息中还可以携带受到 干扰的 UE所属的小区的邻区中非干扰小区的标识, 以及针对邻区中的 非干扰小区的干扰协调请求信息, 该干扰协调请求信息指示邻区中的非 干扰小区不进行干扰协调请求。
相邻基站收到该第一消息后可以将非干扰小区的标识和针对非干扰 小区的干扰协调请求消息存储起来, 后续产生干扰的时候可以利用该存 储消息进行干扰协调,也可以利用该消息统计相邻小区之间干扰的程度。
在本实施例中, 上述第一消息可以是负载消息 ( Load Information ), 并可以在负载消息中的 RNTP信元中携带上述第一消息中的信息。 在实际的操作中, 可以将干扰小区和非干扰小区统一为目标小区
( Target Cell ID ), 当目标小区为干扰小区时对应的干扰协调请求信息所 对应的值为 1, 而当目标小区为非干扰小区时对应的干扰协调请求信息 所对应的值为 0。 在本实施例中, 也可以在负载消息中的 RNTP信元中 携带目标小区的个数( Target number ) 的信息。
可以理解的是, 已有技术中被干扰的 UE所在的小区的信息, 如被 干扰小区的小区标识、 频带划分方式以及计算干扰所需要的参数仍可以 在携带在该负载消息中一并发送给相邻基站, 相邻基站可以通过该信息 直接得知被干扰的 UE所在的小区以及被干扰 UE所在小区的相关参数。
具体而言,基站 A给基站 B和基站 C发送负载消息,在该负载消息 中包含被干扰的 UE所在的小区 A1 的标识, 还在 RNTP信元中携带小 区 B 1的标识, 以及针对该 B1的干扰协调请求信息, 该干扰协调请求信 息的值为 1, 指示小区 B 1与小区 A1进行下行干扰协调。
在该负载消息的 RNTP信元中还携带小区 C1 的标识, 以及针对该 C1 的干扰协调请求信息, 该干扰协调请求信息的值为 1, 指示小区 C1 与小区 A1进行下行干扰协调。
可选的, 在该负载消息的 RNTP信元中, 还可以携带被干扰的 UE 所在小区的邻区中的非干扰小区。 小区 A1的邻区包括小区 B l、 小区 B2 及小区 Cl。 其中小区 B1和小区 C 1对小区 A1中的 UE产生下行干 4尤, 小区 B2没有对小区 A1 中的 UE产生干扰, 小区 B2为 UE所在小区的 邻区中的非干扰小区。 在本实施例中, 在负载消息的 RNTP信元中还可 以携带小区 B2的标识, 以及针对该 B2的干扰协调请求信息, 该干扰协 调请求信息的值为 0, 指示小区 B2不需要与小区 A1进行干扰协调。 在 实际的消息中, 可以将干扰小区和非干扰小区统一为目标小区, 干扰小 区对应的干扰协调请求信息为 1, 而非干扰小区的干扰协调请求信息为 0, 如表 1所示: » Relative Narrowband Tx Power (RNTP)

在本实施例中, 被干扰的 UE所处小区所属的第一基站在发送的第 一消息中携带了干扰小区的标识, 相邻基站判断本基站中是否有与所接 收到第一消息中的干扰小区标识对应的小区, 若判断结果为是, 则该相 邻基站根据干扰协调请求信息指示干扰小区与被干扰 UE所在的小区进 行干扰协调, 提高了干扰协调请求信息的准确度。
被干扰的 UE所处小区所属的基站在发送的消息中携带该小区邻区 中非干扰小区的标识, 并通过干扰协调请求信息指示该非干扰小区不需 要进行干扰协调, 从而更加明确的区分了需要进行干扰协调的小区和不 需要进行干扰协调的小区, 并且在后续产生干扰的时候可以利用该存储 消息进行干扰协调, 也可以利用该消息统计相邻小区之间干扰的程度。
本实施例在负载消息中的 RNTP信元中携带上述信息, 有利于相邻 基站在收到消息后能根据 RNTP信元中的其他信息, 如被干扰 UE所在 小区的频带划分方式等确定干扰小区干扰协调的具体内容。 当第一基站与相邻基站之间发生干扰为第一基站的小区受到属于相 邻基站小区中的 UE的上行干扰时, 本发明又一实施例详细说明了该干 扰协调方法, 包括以下步骤: 第一基站确定与相邻基站发生了干扰;
在本步骤中, 第一基站确定属于该第一基站的小区受到属于相邻基 站小区中 UE的干扰, 该 UE所属的小区为干扰小区;
假设基站 A的相邻基站有基站 B、 基站 C, 基站 A中有小区 Al、 小区 A2及小区 A3, 基站 B中有小区 Bl、 小区 B2及小区 B3, 基站 C 中有小区 Cl、 小区 C2及小区 C3, 小区 A1的邻区有小区 Bl、 小区 B2 及小区 Cl, 其中小区 A1中受到小区 B1和小区 C1中 UE的上行干扰, 小区 B1和小区 C1为干 ·ί尤小区。
第一基站向相邻基站发送携带干扰小区标识及针对干扰小区的干扰 协调请求信息的第一消息;
在本步骤中, 第一基站向相邻基站发送第一消息, 并在该第一消息 中携带干扰小区标识及针对该干扰小区的干扰协调请求信息, 干扰小区 是指干扰该小区的 UE所属的小区,被干扰小区是指受到干扰小区中 UE 上行干扰的小区, 干扰协调请求信息指示该邻基站在干扰小区和被干扰 小区之间进行上行干扰协调。
由于基站 Α的小区 A1受到小区 B1和小区 C1中 UE的干扰, 基站 A向基站 B和基站 C发送第一消息, 希望基站 B中的小区 B1与基站 A 中的小区 A1进行上行干扰协调, 以及基站 C中的小区 C1与基站 A中 的小区 A1进行上行干扰协调。
基站 A发送的第一消息中可以包括小区 B1的标识, 以及针对该小 区 B1的干扰协调请求信息,指示小区 B1与小区 A1进行上行干扰协调。 基站 A发送的消息中还可以包括小区 C1 的标识, 以及针对该小区 C1 的干扰协调请求信息, 指示小区 C1与小区 A1进行上行干扰协调。
该第一消息中还可以携带小区 A1的信息,如小区 A1的标识频带划 分方式及计算干扰所需要的参数。
相邻基站判断自身的小区中是否有干扰小区标识所对应的干扰小 区, 若判断结果为是, 则执行步骤 a, 若判断结果为否, 则执行步骤 b ; 在本步骤中, 该相邻基站通过判断属于自身的小区中是否有第一消 息中所携带的干扰小区标识对应的小区来判断自身的小区中是否有干扰 小区, 若判断结果为是, 说明该相邻基站自身的小区中有干扰小区, 则 执行步骤 a, 若判断结果为否, 说明该相邻基站自身的小区中没有干扰 小区, 则执行步骤 b。
基站 B收到基站 A发送的第一消息后,识别该第一消息中携带的小 区标识, 并将第一消息中的小区标识与基站 B 自身中包含的小区的标识 相比较, 判断基站 B中是否有与该第一消息中小区标识相一致的小区。 基站 B判断该第一消息中有小区 Bl, 而基站 B中有小区 Bl, 则基站 B 判断自身的小区中有干扰小区, 执行步骤 &。 同样, 基站 C收到基站 A 发送的第一消息中携带小区 C 1的标识, 而基站 C中有小区 C l, 则基站 C判断自身的小区中有干扰小区, 执行步骤 。
假设基站 D也是基站 A的相邻基站, 基站 A还向基站 D发送了该 第一消息, 基站 D收到第一消息之后识别该第一消息中包含小区 B1和 小区 C1的标识, 而属于基站 D的小区中没有这两个小区, 因此基站 D 判断自身的小区中没有干扰小区, 执行步骤1?。
步骤 a: 相邻基站根据干扰协调请求消息, 进行干扰小区和被干扰 小区之间的上行干扰协调;
若判断结果是属于相邻基站的小区中有干扰小区, 相邻基站根据干 扰协调指示在干扰小区与受到干扰的小区进行干扰协调, 即相邻基站根 据干扰协调请求进行干扰小区和被干扰小区之间的上行干扰协调。
基站 B根据干扰协调指示, 在小区 B 1和小区 A1之间进行干扰协 调。 由于在现有技术中基站之间发送的负载消息中的高干扰指示 (High Interference,简称 HII)信元中包含被干扰的 UE所在小区 A 1的频带划分 方式, 基站 B根据该频带划分方式, 协调小区 B 1的频带, 使得小区 B1 和小区 A1错开高功率频带, 达到上行干扰协调的目的。
步骤 b, 相邻基站存储第一消息中的信息, 或不进行操作, 或继续 等待后续消息;
判断结果是属于相邻基站的小区中没有干扰小区, 相邻基站存储第 一消息中的信息, 或者根据干扰协调请求消息不进行干扰协调, 或者继 续等待后续消息。
以基站 D为例, 基站 D判断基站 D中没有干扰小区, 则基站 D进行 以下操作之一或组合: 存储该第一消息中的信息, 或者, 依据所接收到 的第一消息中的干扰协调请求不进行干扰协调,或者继续等待后续消息。
在本实施例中, 第一消息还可以携带受到干扰的小区的邻区中非干 扰小区的标识, 以及针对邻区中的非干扰小区的干扰协调请求信息, 该 干扰协调请求信息指示邻区中的非干扰小区不进行干扰协调请求。
相邻基站收到该第一消息后可以将该第一消息中的非干扰小区的标 识, 以及针对邻区中的非干扰小区的干扰协调请求信息存储起来, 在后 续产生干扰的时候可以利用该存储消息进行干扰协调, 也可以利用该消 息统计相邻小区之间干扰的程度。
在本实施例中,上述第一消息可以是负载消息,在负载消息中的 ΗΠ 信元中携带上述信息。
在实际操作中, 可以将干扰小区和非干扰小区统一为目标小区。 当 目标小区为干扰小区时对应的干扰协调请求信息所对应的值为 1, 而当 目标小区为非干扰小区时对应的干扰协调请求信息所对应的值为 0。 在 本实施例中, 也可以在第一消息中携带目标小区的个数的信息。
可以理解的是, 已有技术中该被干扰的小区的信息, 如被干扰小区 的小区标识、 频带划分方式以及计算干扰所需要的参数仍可以在携带在 该负载消息中一并发送给相邻基站, 相邻基站可以通过该信息直接得知 被干扰的小区以及被干扰 UE所在小区的相关参数。 具体而言,基站 A给基站 B和基站 C发送负载消息,在该负载消息 中包含被干扰的小区 A1 的标识, 还在该负载消息的 HII信元中携带小 区 B 1的标识, 以及针对该 B1的干扰协调请求信息, 该干扰协调请求信 息的值为 1, 指示小区 B 1与小区 A1进行上行干扰协调。
在该负载消息的 HII信元中还携带小区 C1的标识, 以及针对该 C1 的干扰协调请求信息, 该干扰协调请求信息的值为 1, 指示小区 C1与小 区 A1进行上行干扰协调。
在该负载消息的 HII信元中, 还可以携带被干扰的 UE所在小区的 邻区中的非干扰小区的小区标识以针对该非干扰小区的干扰协调请求。 小区 A1的邻区包括小区 Bl、 小区 B2及小区 Cl。 其中小区 B1和小区 C1为干扰小区, 小区 B2中的 UE没有对小区 A1产生干扰, 小区 B2为 小区 A1 的邻区中的非干扰小区。 在负载消息的 HII信元中还可以携带 小区 B2的标识, 以及针对该 B2的干扰协调请求信息, 该干扰协调请求 信息的值为 0, 指示小区 B2不需要与小区 A1进行干扰协调。 如表二所

表二
在本实施例中, 被干扰的小区所属的基站在发送的消息中携带了干 扰小区的标识, 相邻基站判断本基站中是否有干扰小区, 如果有干扰小 区, 则该相邻基站根据干扰协调请求信息指示干扰小区与被干扰的小区 进行干扰协调, 提高了干扰协调请求信息的准确度。
被干扰的小区所属的基站在发送的消息中携带该小区邻区中非干扰 小区的标识, 并通过干扰协调请求信息指示该非干扰小区不进行干扰协 调, 从而更加明确的区分了需要进行干扰协调的小区和不需要进行干扰 协调的小区。
本实施例在负载消息中的 HII信元中携带上述信息, 有利于相邻基 站在收到消息后能同时根据 HII信元中的其他信息, 如被干扰小区的频 带划分方式等, 确定干扰小区干扰协调的具体内容。 图 4为本发明实施例的干扰协调系统结构示意图, 如图 4所示, 本 发明实施例的干扰协调系统包括: 确定模块 401、 发送模块 402、 干扰协 调模块 403。

根据第一消息中携带的干扰小区标识, 干扰协调模块 403根据发送 模块 402所发送的第一消息中的干扰小区标识和针对该干扰小区标识的 干扰协调请求信息进行干扰小区与被干扰小区之间的干扰协调。 可以理 解的是, 该干扰协调模块 403可以设置在相邻基站中。
本实施例在确定模块确定第一基站与相邻基站发生干扰之后, 发送 模块向相邻基站发送第一消息, 并在该第一消息中包含携带目标干扰小 区标识和针对该干扰目标小区的干扰协调请求信息, 相邻基站的干扰协 调模块根据该第一消息进行干扰协调。 避免了相邻基站受到消息后由于 无法确定是否需要干扰协调而引起的无限制协调和单向协调的同时, 提 高干扰协调的效率, 降低通信的干扰, 增加通信的稳定性。 当第一基站与相邻基站之间发生的干扰为第一基站的小区中的 UE 受到属于相邻基站的小区的下行干扰时, 本发明另一实施例详细说明了 该干扰协调系统。图 5为本发明另一实施例的干扰协调系统结构示意图, 如图 5所示, 本发明另一实施例的干扰协调系统包括: 确定模块 501、 发送模块 502、 干扰协调模块 503, 其中,

假设第一基站 A的相邻基站 B中有小区 B l、 小区 B2及小区 B3, 基站 A中小区 A1中的 UE测量到小区 B1,小区 A1中的 UE受到基站 B 中小区 B 1的下行干扰, 则确定模块 501可以确定基站 A与基站 B发生 了干扰。
