Description

一种***信息的接收方法和装置 技术领域
本发明涉及无线通信技术领域， 尤其涉及一种***信息的接收方法和装 置。 背景技术
在无线蜂窝通信***中， 基站是为用户设备 ( UE , User Equipment )提 供无线接入的设备， 一个基站可能包括一个或多个服务小区。 小区能够为一 定地理范围的 UE提供通信服务， 不同的小区可能有不同的覆盖范围， 通常 可以根据小区的覆盖范围以及部署的目的将小区分成宏小区 （macro cell ) 、 微小区 （pico cell )、 微微小区（femto cell )等， 相应地， 提供这些小区用户 接入服务的基站又可称为宏基站、 微基站、 家庭基站等。 小区还可以有不同 的接入模式（access mode ) ： 通常一个普通的小区可以为任何用户提供接入 服务， 这种小区称为开放小区； 而针对在家庭或企业等应用环境下需要限定 允许接入的用户的需求， 一个封闭用户组（CSG, Closed Subscriber Group ) 小区 （称为封闭型 （Closed ) 小区） 只能允许规定的用户 （即成员）接入； 或者一个混合型 （hybrid ) 小区在优先为成员用户提供接入的同时， 也可以 为非成员用户提供接入服务。
随着无线通信网络技术的发展， 会出现在相同的或者相邻的地区由两种 或者多种不同类型小区覆盖的场景， 例如在 Macro Cell覆盖范围内部署 Pico Cell来承担负载均衡或者覆盖增强， 再例如在 Macro Cell覆盖范围内家庭用 户还会部署 Femto Cell来承担室内覆盖。 这种由多种类型小区共同完成无线 接入覆盖的场景可以称为异构网络 ( heterogeneous network , 简称为 hetnet ) 场景。 在异构网络场景下， 一些新的网络部署方案以及技术不断出现， 例如 为了让 Pico Cell服务更多的用户并进而承担更多的业务流量，会引入小区边 缘扩展（CRE, Cell Range Extension )技术。 但是， 由于处于小区边缘扩展 区域，用户受到的 Macro Cell的干扰地较大，为了降低对于 Pico小区的干扰， 在 Macro Cell与 Pico Cell共存的异构网络场景下，会引入降低功率传输的几 乎为空子帧 （ ABS, Almost Blank Subframe ) ， 为了降低对相邻 Pico小区的 干扰， Macro 小区会尽量避免或降低功率在 ABS 上的物理下行共享信道 ( PDSCH, Physical Downlink Shared Channel )上传输下行业务数据。
引入 ABS可以部分降低干扰小区对被干扰小区服务的处于干扰位置，例 如上述的 CRE区域， 的 UE数据传输的干扰， 但是并没有办法解决一些特殊 消息的传输干扰， 例如***消息传输干扰。 按照相关技术的设计， ***消息 (包括 MIB以及其他的 SIB***消息）由于其传输时域位置已由***固定配 置， 并且 MIB消息传输的频域位置更进一步地由***固定配置。 在 LTE系 统中 , MIB消息在 FDD以及 TDD***中都固定在无线帧的第 1个时隙的前 4个符号中发送，并且在频域上占据***带宽的中间 6个物理资源块 ( Physical Resource Block, PRB ) , ***消息块 1 ( System Information Block, SIB1 ) 在 FDD以及 TDD***中则固定被***配置为在偶数无线帧的第 5个子帧进 行传输。 干扰小区为了保证其服务的 UE可以正常的接收服务， 即使会对被 干扰小区的***消息传输造成干扰， 也必须要按照***配置在所述固定位置 上使用正常的功率传输***消息。 从上面的分析可以看到， 相关技术中， 系 统消息之间的传输干扰无法通过引入 ABS的机制进行解决。 在上述的 CRE 区域中， 受干扰基站服务的 UE接收受干扰小区的***消息时会受到干扰小 区的强干扰并进而导致其无法正常接收受干扰小区发送的***消息以及相应 的***消息的更新。 而***消息的无法正常接收将导致 UE在网络中接收服 务收到严重影响。
目前尚未有针对上述问题的研究以及相应的解决方法。
发明内容
有鉴于此， 本发明实施例提供一种***信息的接收方法和装置， 解决处 于干扰区域 UE由于受到相邻小区干扰而无法从服务小区所述固定位置接收 ***消息的问题。
本发明实施例提供一种***信息的接收方法， 包括：
UE从***配置的固定位置之外的其它位置接收服务小区和 /或相邻小区 的***信息和 /或***信息更新指示。 本发明实施例还提供一种用户设备， 包括：
接收模块， 其设置为： 从***配置的固定时域和 /或频域位置之外的其它 位置接收服务小区和 /或相邻小区的***信息和 /或***信息更新指示。
本发明实施例还提供一种基站， 包括：
发送模块， 其设置为： 从***配置的固定时域和 /或频域位置之外的其它 位置向用户设备发送所述用户设备的服务小区和 /或相邻小区的***信息和 / 或***信息更新指示。
本发明实施例还提供另一种***信息的接收方法， 包括：
UE从服务小区接收干扰消除操作所需要的辅助信息；
所述 UE根据所述辅助信息执行***信息接收操作时的干扰消除操作。 本发明实施例还提供一种另用户终端， 包括：
接收单元，其设置为：从服务小区接收干扰消除操作所需要的辅助信息； 干扰消除单元， 其设置为： 根据所述辅助信息执行***信息接收操作时 的干扰消除操作。
通过釆用本发明实施例提供的方法和装置， 用户设备可以在***配置的 固定位置之外的其它位置接收***信息， 从而解决了相关技术中由于固定位 置的***信息干扰导致用户终端无法获得***信息的问题。 附图概述

为使本发明的目的、 技术方案和优点更加清楚明白， 下文中将结合附图 对本发明的实施例进行详细说明。 需要说明的是， 在不冲突的情况下， 本申 请中的实施例及实施例中的特征可以相互任意组合。
图 1为异构网络的覆盖示意图， 如图 1所示， 一个典型的异构网络场景 包括宏基站小区 （Macro Cell )以及微基站小区 （ Pico Cell )以及微微基站小 区（ Femto Cell )。其中 Pico Cell覆盖区域中应用了 CRE机制以提高 Pico Cell 的覆盖范围。 为了保护处于 Pico CRE区域由 Pico服务的 UE的数据传输以 及处于 Femto覆盖区域由 Macro服务的 UE的数据传输， ***会引入 ABS。 引入 ABS可以降低干扰小区对被干扰小区服务的处于干扰位置的 UE, 例如 图示中 CRE区域的 UE, 数据传输的干扰。 但是干扰小区的一些下行公共控 制信道调度的信息的传输， 例如***消息， 由于干扰小区需要保证其服务的 UE不被影响， 所以即使***消息传输的子帧被配置为 ABS, ***消息也需 要正常在 ABS上传输。 进而， 在上述的 CRE区域中， 受干扰基站服务的 UE 接收受干扰小区的***消息时会受到干扰小区传输***信息而带来的强干 扰， 并进而导致其无法正常接收受干扰小区发送的***消息以及相应的*** 消息的更新。 而***消息的无法正常接收将导致 UE在网络中接收服务受到 严重影响。

干扰小区所属基站按照现有***中定义的切换操作机制以及针对相邻小 区配置的小区相关的偏移参数和 /或 201的相邻基站的配置交互，确定相邻的 被干扰小区为切换操作的侯选目标小区。 并且， 进而干扰小区所属基站与被 干扰小区所属基站之间交互 UE切换操作所需要的信令消息。 此处的切换操 作包含在干扰小区所属基站与被干扰小区所属基站之间的 X2切换操作流程 以及 S1切换操作流程。
203 , 切换操作的源小区、 以及目标小区发送切换命令消息到 UE。
源小区需要将一些信息发送到 UE,并进而使 UE可以获取相邻目标小区 的***信息，此处的***信息包含主信息块（ Master Information Block, MIB )、 ***消息块 1 ( System Information Block 1, SIB1 ) 以及其他目标小区发送的 ***信息。
针对 UE获取目标小区的 MIB信息包括以下方式：
( 1 ) 源小区将目标小区的***帧号和 /或源小区与目标小区***帧号之 间的关系和 /或计算获取目标小区的***帧号需要的修正参数发送到 UE。 所 述***帧号之间的关系包括源小区与目标小区***帧号之间的差值和 /或倍 数关系或者其它的基于源小区的当前***帧号以及所述关系可获取目标小区 ***帧号的关系。 UE接收到所述明确的目标小区***帧号时， 并且***配 置了相应的修正规则， 例如在获知的明确的***帧号基础上 1入修正操作即 可获知目标小区的当前***帧号， 则 UE执行相应的修正操作以获取目标小 区的***帧号。 和 /或
当 UE接收到的是所述的***帧号之间的关系时， 则 UE基于当前服务 小区的***帧号以及所述***帧号之间的关系计算获取相邻目标小区的*** 帧号。 并且， UE接收到的是获取所述目标小区的***帧号的修正参数以及 所述关系时时， 则 UE根据该修正参数以及所述关系进行操作得到目标小区 的当前***帧号。
UE可以从服务基站发送的广播消息和 /或切换命令之外的其他 RRC信令 消息中接收到所述***帧号和 /或所述***帧号之间的关系； 如果 UE从服务 基站发送的广播消息中接收， 则***可以配置 UE从服务基站获取接收所述 广播消息的方式， 所述接收所述广播消息的方式包括广播信息传输的时域位 置和 /或频域位置和 /或功率信息和 /或调度信息和 /或发送接收编解码信息， 进 一步地包括 UE可以从服务基站获取所述接收广播消息的方式并按照所述广 播消息接收方式接收所述广播消息；所述切换命令之外的其他 RRC信令包括 无线连接重配置消息。
( 2 )如果***配置小区可以在现有的固定位置之外的其它位置发送*** 消息， 例如， 在现有 LTE***中规定， MIB消息在 FDD以及 TDD***中 都固定在无线帧的第 1个时隙的前 4个符号中发送， 并且在频域上占据*** 带宽的中间 6个物理资源块（ Physical Resource Block, PRB ) , 则 UE可以 从服务基站接收获取相邻小区在所述固定位置之外的其它位置发送所述*** 消息的方式的信息， 所述发送***消息的方式的信息包括发送***消息的时 域位置和 /或频域位置和 /或功率信息和 /或调度信息和 /或发送接收编解码信 息； 所述发送方式包括单播 RRC信令消息和 /或广播消息； UE可以从服务基 站基于广播消息和 /或单播 RRC信令获取所述相邻小区在所述固定位置之外 的其它位置发送所述***消息的方式的信息。 当 UE获取了所述相邻小区在 所述其它位置发送***消息的方式的信息后， 则 UE可以按照获取的所述目 标小区发送***消息的方式从相部目标小区接收***消息。
针对 UE获取目标小区的 SIB信息（包括 SIB1以及其他 SIB模块 )包括 以下方式：
如果***配置小区可以在现有的固定位置之外的其它位置发送***消 息，例如，在现有 LTE***中规定， ***消息块 1 ( System Information Block, SIB1 )在 FDD以及 TDD***中固定被***配置为在偶数无线帧的第 5个子 帧进行传输。 如果***配置小区可以在所述固定位置之外的其它位置发送所 述***消息， 则 UE可以从服务基站接收获取相邻目标小区在所述固定位置 之外的其它位置发送所述***消息的方式的信息， 所述发送***消息的方式 的信息包括发送***消息的时域位置和 /或频域位置和 /或功率信息和 /或调度 信息和 /或发送接收编解码信息； 所述发送方式包括单播 RRC信令消息和 /或 广播消息； UE可以从服务基站基于广播消息和 /或单播 RRC信令获取所述相 邻小区在所述固定位置之外的其它位置发送所述***消息的方式的信息。 当 UE 获取了所述相邻小区在所述其它位置发送***消息的方式的信息后， 则 UE可以按照获取的所述发送***消息的方式从相邻目标小区接收***消息。
204, UE获取相邻小区***信息。

205, UE, 干扰小区， 被干扰小区完成其余的网络切换操作。
实施例二
本发明实施例二提供的***信息和 /或***信息更新指示的接收方法应 用于 UE从服务小区接收***信息和 /或***信息更新指示的场景， 如图 3所 示， 包括以下步骤：
301 , UE接入网络。
此操作包括 UE的切换接入、 初始接入、 重建接入等各种网络接入的场 景。
302, 服务基站判断 UE需要增强的***信息和 /或***信息更新指示接 收机制。
UE接入网络后， 由于 UE接收信号的信道状态的变化， 例如， UE可能 会由于移动而进入相邻小区强干扰的区域， UE 可能会无法达到***对于系 统信息和 /或***信息更新指示接收的要求。
服务基站可以基于 UE对于信道状态的测量结果进行判断， 所述信道状 态的测量结果包括 UE对于服务基站的 RRM(包括 RSRP、 RSRQ )和/或 RLM 和 /或 CQI和 /或 SNR和 /或 SINR的测量结果进行判断， 当所述测量结果低于 ***配置的门限值时， 则服务基站可以判断 UE需要执行增强的***信息和 / 或***信息更新指示接收机制； 当所述测量结果高于***配置的相应门限值 时， 则服务基站可以判断 UE不需要执行增强的***信息和 /或***信息更新 指示接收机制。 服务基站也可以基于 UE的数据成功收发情况进行判断， 当 UE的数据收发成功率低于***配置的门限值时，则服务基站可以判断 UE需 要执行增强的***信息和 /或***信息更新指示接收机制， 当 UE的数据收发 成功率高于***配置的相应门限值时， 则服务基站可以判断 UE不需要执行 增强的***信息和 /或***信息更新指示接收机制。
303 , 服务基站指示 UE执行增强的***信息和 /或***信息更新指示接 收机制。 基于 302的步骤， 当服务基站判断出 UE需要执行增强的***信息和 /或 ***信息更新指示接收机制， 则服务基站需要发送相应的包含指示信息的 RRC消息到 UE以指示 UE其需要执行增强的***信息和 /或***信息更新指 示接收机制的状态。 所述 RRC消息可以为现有的 RRC信令， 包括无线连接 重配置信息，也可以是新增加的 RRC消息。所述指示信息可以为在现有消息 中添加新的明确的信元（ Information Element , IE ) , 也可以是使用现有的信 元进行指示， 例如当***配置 UE测量约束信息时， 包括对于服务小区和或 / 相邻小区的 RLM和 /或 RRM和 /或 CQI和 /或 SNR和 /或 SINR测量约束信息 , 则同时表明服务基站指示 UE需要执行增强的***信息和 /或***信息更新指 示接收机制。
如果所述的增强的***信息和 /或***信息更新指示接收机制为 UE需要 在现有***配置的所述固定位置之外的其他位置接收服务基站广播的***信 息和 /或***信息更新指示， 则服务基站还可以在该步骤中传输 UE从服务基 站获取接收所述固定位置之外的其它位置传输广播的***消息的方式， 所述 接收广播的***消息的方式包括***信息广播传输的时域位置和 /或频域位 置和 /或功率信息和 /或调度信息和 /或发送接收编解码信息。
304, UE执行增强的***信息和 /或***信息更新指示接收机制。
UE执行增强的***信息和 /或***信息更新指示接收机制包括以下几种 方式：
1 )UE同时尝试接收服务小区在所述固定位置发送的***信息和 /或*** 信息更新指示， 以及服务小区在所述固定位置之外位置发送的***信息和 / 或***信息更新指示， 包括 MIB和 /或 SI消息中包含的信息；
2 ) UE判断所述状态为其不能够接收服务小区在固定位置广播发送的系 统信息和 /或***信息更新指示的状态时， 则 UE不尝试解码接收服务小区在 所述固定位置广播发送的***信息和 /或***信息更新指示对应的物理控制 信道和 /或下行数据共享信道。
如果 UE在 303中获取了从服务基站接收所述固定位置之外的其它位置 传输的广播***信息和 /或***信息更新指示的方式， 则 UE按照其获取的接 收所述固定位置之外的其它位置传输的广播***信息和 /或***信息更新指 示的方式信息接收服务基站在所述固定位置之外的其它位置传输的广播*** 信息和 /或***信息更新指示。
当 UE接收到当前服务小区与相邻小区之间***帧号之间的关系时， 会 基于服务基站的配置或者主动的获取相邻小区的当前***帧号， 所述服务基 站的配置包括服务基站需要明确的配置所述***帧号关系对应的相邻小区的 小区标识以及针对相邻小区的测量配置信息。 UE基于接收到的相邻小区的 当前***帧号和所述***帧号之间的关系来计算获取服务小区的当前***帧 号； 所述计算方式可以使用前述实施例中描述的方法。
305, 服务基站指示 UE不需要继续执行增强的***信息和 /或***信息 更新指示接收机制。
如 302中所述的方法， 服务基站可以继续判断 UE是否需要继续执行增 强的***信息和 /或***信息更新指示接收机制。
当服务基站判断 UE不需要继续执行增强的***信息和 /或***信息更新 指示接收机制时， 则服务基站可以通过包含明确的或者间接的指示信息的 RRC信令到 UE; 所述 RRC信令包括无线连接重配置消息； 所述明确的指示 信息包括在 RRC信令中添加信元或者使用已有的信元进行间接指示。 较佳 地， 当 UE接收到服务基站释放配置给 UE的测量约束的信息时， 包括对于 服务小区和或 /相邻小区的 RLM和 /或 RRM和 /或 CQI和 /或 SNR和 /或 SINR 测量约束信息， 则同时表明服务基站指示 UE不需要执行增强的***信息和 / 或***信息更新指示接收机制。 此时， 当服务基站基于单播方式传送***信 息和 /或***信息更新指示给 UE时， 则服务基站停止再传输单播的***信息 和 /或***信息更新指示到所述 UE; 当在 304的操作步骤中， UE在执行增强 的***信息和 /或***信息更新指示接收机制时则不接收服务小区在固定位 置发送的***信息和 /或***信息更新指示时， 则 UE在接收到服务基站指示 的 UE不需要继续执行增强的***信息和 /或***信息更新指示接收机制的信 令消息时， 则 UE需要开始按照***配置的方法接收服务小区在固定位置发 送的***信息和 /或***信息更新指示。
实施例三 本发明实施例三提供的***信息和 /或***信息更新指示的接收方法应 用于 UE从服务小区接收***信息和 /或***信息更新指示的另一场景， 如图 4所示， 包括以下步骤：
401 , UE接入网络；
此步骤应用的场景以及包含的操作内容与实施例二中相同，此处不重复 赘述。
402, UE 判断需要执行增强的***信息和 /或***信息更新指示接收机 制。
UE接入网络后， 由于 UE接收信号的信道状态的变化， 例如， UE可能 会由于移动而进入相邻小区强干扰的区域， UE 可能会无法达到***对于服 务基站***信息和 /或***信息更新指示接收的要求。
UE判断的方式包括以下之一：
1 ) UE测量的信道状态， 包括如前述实施例中描述的无线资源管理 RRM 和 /或 RLM和 /或 CQI和 /或 SNR和 /或 SINR的测量结果。 如果 UE的测量结 果基于基站配置的判断规则以及判断门限满足其需要执行增强的***信号接 收机制的条件， 则认为 UE需要继续执行增强的***信息和 /或***信息更新 指示接收机制。 其中， 判断门限由基站发送， 发送时间在 UE执行判定之前， 例如在 UE接入网络时下发。 所述服务基站发送所述判定门限的方式包括广 播发送和 /或单播 RRC信令消息发送的方式。
2 )UE成功解码服务小区在固定位置传输的***信息和 /或***信息更新 指示的概率低于 UE从服务基站接收到的判定门限。
403 , UE指示基站该 UE需要执行增强的***信息和 /或***信息更新指 示接收机制。
如果在 402步骤中， UE判定需要执行增强的***信息和 /或***信息更 新指示接收机制， 则所述 UE给所述服务基站发送携带直接或者间接指示信 息的信令，所述直接指示信息信令包括在现有信令消息和 /或新增信令消息中 添加新的信元， 所述间接指示信息信令包括在现有 RRC信令消息和 /或新增 信令消息中扩充现有信元和 /或现有信元组合的含义来进行指示； 404, 服务基站基于 UE的指示执行相应的操作。
当服务基站收到 UE不可以接收服务小区在固定位置广播发送的***信 息和 /或***信息更新指示的状态指示时， 当服务基站判定后续 UE需要获取 ***信息和 /或***信息更新指示时， 例如发生了***信息和 /或***信息更 新指示的更新，则使用所述固定位置之外其它位置传输的单播和 /广播消息发 送所述***信息和 /或***信息更新指示给 UE。
需要说明，如果服务基站釆用广播的方式下发***信息和 /或***信息更 新指示， 则服务基站还需要告知 UE广播***信息和 /或***信息更新指示的 方式， 包括广播信息传输的时域位置和 /或频域位置和 /或功率信息和 /或调度 信息和 /或发送接收编解码信息。
405, UE指示其是否需要继续执行增强的***信息和 /或***信息更新指 示接收机制。
UE在执行了 403步骤中的操作，即发送了指示 UE需要执行增强的*** 信息和 /或***信息更新指示接收机制到服务基站后， 还可以继续执行 UE是 否需要执行增强的***信息和 /或***信息更新指示接收机制的判断，具体的 判断操作如下：
UE判断的方式包括以下之一：
1 ) UE测量的信道状态， 包括如前述实施例中描述的无线资源管理 RRM 和 /或 RLM和 /或 CQI和 /或 SNR和 /或 SINR的测量结果， 高于某一门限则认 为 UE不需要继续执行增强的***信息和 /或***信息更新指示接收机制；
2 ) UE同时尝试接收服务小区在所述固定位置以及固定位置之外的其它 位置传输发送的***信息和 /或***信息更新指示， 则 UE可以判断并指示服 务小区其是否能够接收服务小区在固定位置广播方式发送的***信息和 /或 ***信息更新指示的状态。 UE 成功解码服务小区在固定位置传输的***信 息和 /或***信息更新指示的概率高于***配置的判定门限，则认为其不需要 继续执行增强的***信息和 /或***信息更新指示接收机制；
当 UE判断其不需要继续执行或者判断其需要继续执行增强的***信息 和 /或***信息更新指示接收机制时， 则同样也可以使用 RRC信令和 /或随机 接入码来指示所述状态信息给服务基站。 携带指示信令的方法可以同上述实 施例中的方法；
需要说明， 上述实施例二和三中的判断过程不限于上述描述， 例如也可 以是由 UE判断需要执行增强的***信息和 /或***信息更新指示接收机制， 而由服务基站判断不需要继续执行增强的***信息和 /或***信息更新指示 接收机制；或者由服务基站判断需要执行增强的***信息和 /或***信息更新 指示接收机制， 而由 UE判断不需要继续执行增强的***信息和 /或***信息 更新指示接收机制， 本发明实施例对此不做限制。
通过釆用本发明实施例提供的方法， 用户设备可以在***配置的固定位 置之外的其它位置接收***信息和 /或***信息更新指示，从而解决了现有技 术中由于固定位置的***信息和 /或***信息更新指示干扰导致用户设备无 法获得***信息和 /或***信息更新指示的问题。
实施例四
由于干扰小区与被干扰小区按照***配置的固定位置发送***信息和 / 或***信息更新指示， 故受干扰区域的 UE接收被干扰小区的***信息和 /或 ***信息更新指示会受到干扰小区***信息和 /或***信息更新指示的干扰。 本发明实施例四提供另一种***信息的接收方法， 基于干扰消除接收***信 息和 /或***信息更新指示， 如图 5所示， 包括以下步骤：
501 , 基站之间交互相邻小区的配置信息。
如前述实施例中所述， 干扰基站与被干扰基站之间可以交互一些基站的 配置信息。 在此实施例中， 基站之间交互信息的目的主要是为后续的***信 息和 /或***信息更新指示接收时的干扰消除操作， 故主要包括以下内容： 基 站之间交互相邻小区物理广播信道（PBCH )传输的信息， 包括下行带宽和 / 或物理反馈信道 PHICH配置和 /或物理帧号和 /或相邻小区物理帧号之间的关 系和 /或相邻小区传输所述信息所使用的调制编码方式和 /或码率信息。
502, UE接入网络。
此步骤应用的场景以及包含的操作内容与前述实施例中相同， 此处不再 赘述。
503 , UE指示其干扰消除的能力到服务基站。
此步骤的目的是为了让基站可以获知 UE具备接收服务小区 PBCH信息 时候对于相邻干扰小区的 PBCH传输造成的干扰的干扰消除能力， 包括以下 方式：
1 ) UE使用包含独立的能力指示信息的 RRC信令到服务基站， 包括在 UE Capability Information信令消息中携带；
2 ) UE使用其余的能力指示间接的其干扰消除的能力， 例如 UE的版本 信息， UE的相邻干扰小区干扰参考信号的干扰消除能力都可以与 UE接收 PBCH信息时的干扰消除能力相对应。
3)当 UE接收到服务基站发送的执行干扰消除操作需要的辅助信令时， UE不发送响应消息，或者 UE发送包含不支持或者支持干扰消除能力指示信 息的响应消息到基站以通知基站其不支持或者支持干扰消除能力； 所述响应 消息中包含指示信息的方式也可以使用前述的直接和 /或间接的方式表示； 服务基站获取到 UE的干扰消除能力后可以按照现有能力信息处理机制 处理所述接入能力， 包括将所述能力传输到核心网网元（包括 MME ) 以及 切换操作过程中携带到目标基站等操作；
504, UE从服务小区获取***信息和 /或***信息更新指示接收干扰消除 操作所需要的辅助信息。
此步骤中的服务小区为所述异构网络场景中的被干扰小区， 例如
Macro-Pico场景中的 Pico小区。 Pico小区将 501中获取的相邻干扰小区在物 理广播信道上传输的信息以及相应的配置信息发送到 UE。
505, UE接收服务小区的***信息和 /或***信息更新指示。
UE基于获取的干扰小区在物理广播信道上传输的信息以及相应的配置 信息执行接收服务小区 PBCh信息时的干扰消除操作。 所述干扰消除操作包 括在接收到的信号中除去干扰小区发送的干扰信号造成的干扰的操作。 较佳 地， UE从当前服务小区获取所述固定位置发送的小区***信息。
本实施例中描述的方法也可以应用到 UE由干扰小区服务， 但是同时需 要接收与多个干扰小区相邻的被干扰小区的***信息和 /或***信息更新指 示的场景； 干扰小区可以发送被干扰小区相邻的其余的干扰小区在 PBCH上 传输的信息内容以辅助 UE执行接收被干扰小区时的***信息和 /或***信息 更新指示接收时的干扰消除操作。 干扰小区可以通过所述被干扰小区间接地 或者直接通过所述被干扰小区相邻的其余干扰小区获取到所述相邻的其余的 干扰小区在 PBCH上传输的信息内容；
