Description

控制信息发送方法 技术领域 本发明涉及通信领域， 具体而言， 涉及控制信息发送方法。 背景技术 在无线通信系统中， 基站是为终端提供服务的设备， 基站通过上 /下行 链路与终端进行通信， 其中， 下行（前向）是指基站到终端的方向， 上行（反 向） 是指终端到基站的方向。 在基站与终端进行数据传输时， 多个终端可以 同时通过上行链路向基站发送数据， 也可以同时通过下行链路从基站接收数 据。 移动网络中的无线覆盖质量能够影响用户享受高速数据、语音服务和视 频服务。 为了实现无线网络的无缝覆盖， 需要解决室内及热点地区的覆盖问 题， 目前主要釆取以下两种方案来实现无线网络的无缝覆盖： 一种是增加宏 基站 （ Macro Base Station, 简称为 Macro BS或 Macro Cell ) 的数量和密度； 另一种是在室内或热点地区安装家庭基站（ Femto Base Station,简称为 Femto Cell或 Femto BS或 Femtocell BS ) (也称为个人基站 ), 4啟基站 （ Pico Base Station, 简称为 Pico Cell或 Pico BS ), 毫基站 （ Micro Base Station, 简称为 Micro Cell或 Micro BS ) 等发射功率较低的小基站。 由于传统的宏基站已经接近频谱使用的容量极限， 因此， 如果再增加功 率较大的宏基站， 只会造成更多的辐射污染， 不会改善室内覆盖问题， 但釆 用 Femto BS、 Pico BS等小基站， 不但可以很好地解决室内及热点地区的覆 盖问题， 而且能够在现有的频谱资源上更大地提高系统容量。 通常， 家庭基站根据服务用户类型的不同， 可进一步分为非公开授权用 户组 （ Closed Subscriber Group, 简称 CSG ) -CLOSE家庭基站、 CSG-OPEN 家庭基站、 OPEN 家庭基站， 其中， CSG-CLOSE 家庭基站只允许授权用户 或需要拨打应急服务（例如， 匪警、 火警等） 的用户接入， CSG-OPEN家庭 基站用户不仅允许授权用户接入， 也允许非授权用户接入， 并且， 优先保证 授权用户的服务质量， OPEN家庭基站允许任何终端接入。 一个宏基站的覆盖区域内可能存在大量的家庭基站，以宏基站为服务基 站的终端进入到 CSG-CLOSE 家庭基站的覆盖区域内， 且该终端不是该 CSG-CLOSE家庭基站的授权用户时， 宏基站在特定资源上发送的控制信息， 例如， IEEE 802.16系列标准中的超帧头信息（ Super frame header,简称 SFH ), 由于 CSG-CLOSE家庭基站在对应资源上发送控制信息 （例如， 家庭基站自 己的超帧头）和 /或数据造成的千扰的影响， 导致该终端无法成功获得宏基站 发送的控制信息。 发明内容 针对相关技术中基站在发送控制信息时由于家庭基站已经在对应的资 源上发送数据或控制信息造成千 4尤而导致终端无法成功获得宏基站发送的控 制信息的问题而提出本发明， 为此， 本发明的主要目的在于提供一种控制信 息发送方案， 以解决上述问题至少之一。 为了实现上述目的， 根据本发明的一个方面， 提供了一种控制信息发送 方法。 艮据本发明的控制信息发送方法包括：家庭基站在基站发送该基站的控 制信息所使用的部分或全部资源上发送该基站的控制信息。 优选地，家庭基站在基站发送该基站的控制信息所使用的部分或全部资 源上传输该基站的控制信息包括： 在基站发送该基站的控制信息的时刻与家 庭基站发送该家庭基站的控制信息的时刻相同的情况下， 该家庭基站在该基 站发送控制信息所使用的部分或全部资源上传输该基站的控制信息。 优选地,家庭基站在基站发送控制信息所使用的部分或全部资源上传输 该基站的控制信息包括： 在基站发送该基站的控制信息的时刻与家庭基站发 送该家庭基站的控制信息的时刻不同的情况下， 该家庭基站在该基站发送控 制信息所使用的部分或全部资源上传输该基站的控制信息。 优选地， 上述控制消息为超帧头。 优选地， 以上的时刻以子帧为单位。 优选地，家庭基站在上述资源的子载波上发送的内容与基站在对应子载 波上发送的内容相同。 优选地， 上述基站为以下之一： 宏基站、 毫基站、 微基站、 中继站。 为了实现上述目的， 根据本发明的一个方面， 还提供了一种控制信息发 送方法。 才艮据本发明的控制信息发送方法包括：家庭基站只在基站发送该基站的 控制信息所使用的部分或全部资源以外的资源上传输信令和 /或数据。 优选地，家庭基站只在基站发送该基站的控制信息所使用的部分或全部 资源以外的资源上传输信令和 /或数据包括： 在基站发送该基站的控制信息的 时刻与家庭基站发送该家庭基站的控制信息的时刻不同的情况下， 该家庭基 站只在基站发送该基站的控制信息所使用的部分或全部资源以外的资源上传 输信令和 /或数据。 优选地， 以上的控制消息为超帧头。 为了实现上述目的， 根据本发明的再一个方面， 提供了一种控制信息发 送方法。 根据本发明的控制信息发送方法包括：基站只在家庭基站发送该家庭基 站的控制信息所使用的部分或全部资源以外的资源上传输信令和 /或数据。 优选地，基站只在家庭基站发送该家庭基站的控制信息所使用的部分或 全部资源以外的资源上传输信令和 /或数据包括： 在基站发送该基站的控制信 息的时刻与家庭基站发送该家庭基站的控制信息的时刻相同的情况下， 基站 只在家庭基站发送家庭基站的控制信息所使用的部分或全部资源以外的资源 上传输信令和 /或数据。 优选地，基站只在家庭基站发送该家庭基站的控制信息所使用的部分或 全部资源以外的资源上传输信令和 /或数据包括： 在基站发送该基站的控制信 息的时刻与家庭基站发送该家庭基站的控制信息的时刻不同的情况下， 基站 只在家庭基站发送该家庭基站的控制信息所使用的部分或全部资源以外的资 源上传输信令和 /或数据。 优选地， 以上控制消息为超帧头。 优选地， 上述时刻以子帧为单位。 优选地，家庭基站在上述资源的子载波上发送的内容与基站在对应子载 波上发送的内容相同。 为了实现上述目的， 根据本发明的再一方面， 还提供了一种控制信息发 送方法。 根据本发明的控制信息发送方法包括：基站在家庭基站发送该家庭基站 的控制信息所使用的部分或全部资源上传输该家庭基站的控制信息。 优选地，基站在家庭基站发送该家庭基站的控制信息所使用的部分或全 部资源上传输该家庭基站的控制信息包括： 在基站发送该基站的控制信息的 时刻与家庭基站发送该家庭基站的控制信息的时刻不同的情况下， 基站在家 庭基站发送该家庭基站的控制信息所使用的部分或全部资源上传输该家庭基 站的控制信息。 优选地， 以上的控制消息为超帧头。 通过本发明，釆用了家庭基站在基站发送该基站的控制信息所使用的部 分或全部资源上传输该基站的控制信息； 或者， 家庭基站只在基站发送该基 站的控制信息所使用的部分或全部资源以外的资源上传输信令和 /或数据，解 决了相关技术中基站在发送控制信息时由于家庭基站已经在对应的资源上发 送数据或控制信息造成千扰而导致终端无法成功获得宏基站发送的控制信息 的问题， 进而能够有效的减少控制信息的覆盖盲区， 提高系统的服务质量。 附图说明 此处所说明的附图用来提供对本发明的进一步理解，构成本申请的一部 分， 本发明的示意性实施例及其说明用于解释本发明， 并不构成对本发明的 不当限定。 在附图中： 图 1是 居本发明实施例的帧结构的示意图； 图 2是 居本发明实施例的控制信息发送的流程图； 图 3是根据本发明实施例的不同类型基站发送 SFH所使用的资源的示 意图； 图 4是根据本发明实施例的控制信息发送的另一种实现的流程图;

Macro BS-B在对应子帧上发送超帧头所使用的资源由 N个子载波 （时 域 X频域 ) 构成， 称为子载波集合 B, 而 Femtocell BS-A在对应子帧上发送 超帧头所使用的资源由 M个子载波（时域 X频域）构成，称为子载波集合 A, 且子载波集合 B包含的子载波个数大于子载波集合 A,子载波集合 B与子载 波集合 A的交集非空， 称为子载波集合 C, 则 Femtocell BS-A在子载波集合 B中除子载波集合 C包含的子载波以外的全部或部分子载波（称为子载波集 合 D ) 上发送 Macro BS-B的全部或部分超帧头信息， 且 Femtocell BS-A和 Macro BS-B在子载波集合 D上的相关子载波上发送的内容相同。 由于 Femtocell BS-A发送了 Macro BS-B的超帧头，处于 Femtocell BS-A 覆盖范围内且不能从该家庭基站获得服务的终端 MS-A (假设其服务基站为 Macro BS-B ) 可以在接收 Macro BS-B的超帧头时获得一定的宏分集增益。 实例 2 家庭基站 （ Femtocell BS-A, 记为家庭基站 -A ) 通过空口或骨千网获得 宏基站（ Macro BS-B, 记为宏基站 -B )将要发送的主超帧头和 /或辅超帧头信 息， 且 Femtocell BS-A知道 Macro BS-B在发送超帧头的子帧上釆用的资源 映射方式， 优选地， Femtocell BS-A的覆盖范围位于 Macro BS-B的覆盖范围 内， 或与 Macro BS-B的覆盖范围存在重叠。
Femtocell BS-A和 Macro BS-B在相同的时刻发送超帧头。 图 3是根据本发明实施例的不同类型基站发送 SFH所使用的资源的示 意图； 如图 3所示， Macro BS-B在对应子帧上发送超帧头所使用的资源由 N 个子载波（时域 频域） 构成， 称为子载波集合 B, 而 Femtocell BS-A在对 应子帧上发送超帧头所使用的资源由 M个子载波（时域 X频域）构成， 称为 子载波集合 A, 且子载波集合 B包含子载波集合 A, 即子载波集合 A为子载 波集合 B的子集， 则 Femtocell BS-A在子载波集合 B中除子载波集合 A包 含的子载波以外的全部或部分子载波 （称为子载波集合 C ) 上发送 Macro BS-B的全部或部分超帧头信息， 且 Femtocell BS-A和 Macro BS-B在子载波 集合 C上的每个子载波上发送的内容相同。 由于 Femtocell BS-A发送了 Macro BS-B的超帧头，处于 Femtocell BS-A 覆盖范围内且不能从该家庭基站获得服务的终端 MS-A (假设其服务基站为 Macro BS-B ) 可以在接收 Macro BS-B的超帧头时获得一定的宏分集增益。 图 4是 居本发明实施例的控制信息发送的另一种实现的流程图，如图 4 所示， 假设一种类型的基站和家庭基站发送控制信息的时刻相同， 具体步 骤包括: 步骤 402, —种类型的基站知道家庭基站发送控制信息所使用的资源； 步骤 404, 该类型的基站只能在家庭基站发送该家庭基站的控制信息所 使用的全部或部分资源以外的资源上传输信令和 /或数据。 该类型的基站是宏基站， 或毫基站， 或微基站， 或中继站。 下面结合实施例 3 ~ 4进一步说明图 4所示的流程。 实例 3 宏基站（ Macro BS-B, 记为宏基站 -B )知道家庭基站（ Femtocell BS-A, 记为家庭基站 -A ) 发送主超帧头、 和 /或辅超帧头釆用的资源， 优选地， Femtocell BS-A的覆盖范围可以位于 Macro BS-B的覆盖范围内，或与 Macro BS-B的覆盖范围存在重叠。
Femtocell BS-A和 Macro BS-B在相同的时刻发送超帧头。 图 5是根据本发明实施例的不同类型基站发送 SFH所使用的资源的示 意图， 如图 5所示， Macro BS-B在对应子帧上发送超帧头所使用的资源由 N 个子载波（时 i或 频 i或 ) 构成， 称为子载波集合 B, 而 Femtocell BS-A在对 应子帧上发送超帧头所使用的资源由 M个子载波（时域 X频域）构成， 称为 子载波集合 A,子载波集合 B与子载波集合 A的交集为空，则 居发射功率、 和 /或用户的分布情况， Macro BS-B不能使用子载波集合 A上的全部或部分 子载波进行数据、 和 /或信令的发送。 需要指出， Macro BS-B可以在子载波集合 A发送 Femtocell BS-A在该 子帧上发送的超帧头， 且 Macro BS-B在子载波集合 A上与 Femtocell BS-A 的相关子载波上发送的内容相同。 由于 Macro BS-B发送 Femtocell BS-A的超帧头，以 Femtocell BS-A为 服务基站的终端 MS-A可以在接收 Femtocell BS-A发送的超帧头时获得一定 的宏分集增益。 实例 4 宏基站（ Macro BS-B, 记为宏基站 -B )知道家庭基站（ Femtocell BS-A, 记为家庭基站 -A ) 发送主超帧头、 和 /或辅超帧头釆用的资源， 优选地， Femtocell BS-A的覆盖范围可以位于 Macro BS-B的覆盖范围内，或与 Macro BS-B的覆盖范围存在重叠。
Femtocell BS-A和 Macro BS-B在相同的时刻发送超帧头。 图 6是根据本发明实施例的不同类型基站发送 SFH所使用的资源的示 意图， 如图 6所示， Macro BS-B在对应子帧上发送超帧头所使用的资源由 N 个子载波（时域 频域） 构成， 称为子载波集合 B, 而 Femtocell BS-A在对 应子帧上发送超帧头所使用的资源由 M个子载波（时域 频域）构成， 称为 子载波集合 A, 且子载波集合 A包含子载波集合 B, 即子载波集合 B为子载 波集合 A的子集， 则 居发射功率、 和 /或用户的分布情况， Macro BS-B不 能使用子载波集合 A中除子载波集合 B包含的子载波以外的全部或部分子载 波（称为子载波集合 C ) 上进行数据、 和 /或信令的发送。 需要指出， Macro BS-B可以在子载波集合 A发送 Femtocell BS-A在该 子帧上发送的超帧头， 且 Macro BS-B在子载波集合 C上与 Femtocell BS-A 的相关子载波上发送的内容相同。 由于 Macro BS-B发送 Femtocell BS-A的超帧头，以 Femtocell BS-A为 服务基站的终端 MS-A可以在接收 Femtocell BS-A发送的超帧头时获得一定 的宏分集增益。 图 7、 图 8是才艮据本发明实施例的另一种帧结构的示意图， 如图 7或图 8所示，每个长度为 20ms的超帧（ Super frame )由四个长度为 5ms的帧（ frame ) 构成， 每个 frame由若千个子帧 （ sub frame )构成， 通常为 8个， 每个 frame 都用一个 OFDM符号传输前缀信息（ SA-Preamble or PA-Preamble, 即辅同步 信道或主同步信道）。宏基站和家庭基站都在构成 Super frame的第一个 frame 的第一个 sub frame发送超帧头（ Super Frame Header, 简称 SFH ), 所述 SFH 中携带重要的系统参数信息 （例如频率集合配置、 双工方式等）， 需要注意， 由于宏基站和家庭基站超帧的起始位置不同 （图 7中宏基站的超帧起始位置 位于 PA-Preamble 所在帧的前一帧， 家庭基站的超帧起始位置位于 PA-Preamble 所在帧的后一帧， 图 8 中宏基站的超帧起始位置位于 PA-Preamble 所在帧的前一帧， 家庭基站的超帧起始位置位于 PA-Preamble 所在帧的后的第二帧， 考虑到家庭基站可以支持 low duty mode模式， 优选 图 8所示的帧结构供家庭基站使用）， 所以导致发送 SFH的时刻并不相同。 图 9是 居本发明实施例的控制信息发送的另一种实现的流程图，如图 9 所示， 假设一种类型的基站和家庭基站发送控制信息的时刻不同， 具体步 骤包括： 步骤 902, 家庭基站知道一种类型的基站发送控制信息的时刻及所使用 的资源； 步骤 904, 该家庭基站只能在该类型的基站发送该类型基站的控制信息 所使用的全部或部分资源以外的资源上传输信令和 /或数据。 该类型的基站是宏基站， 或毫基站， 或微基站， 或中继站。 下面结合实施例 5 ~ 6进一步说明图 9所示的流程。 实例 5 家庭基站（ Femtocell BS-A,记为家庭基站 -A )知道宏基站（ Macro BS-B, 记为宏基站 -B )发送主超帧头、 和 /或辅超帧头信息所使用的子帧和资源 （由 标准缺省配置或通过与其它网元的通信获得上述信息）， 优选地， Femtocell BS-A的覆盖范围可以位于 Macro BS-B的覆盖范围内， 或与 Macro BS-B的 覆盖范围存在重叠。

Femtocell BS-A在时刻 T对应的子帧上发送超帧头所使用的资源由 N 个子载波 （时域 X频域） 构成， 称为子载波集合 A, 则 居发射功率、 和 / 或用户的分布情况， Macro BS-B在时刻 T对应的子帧上子载波集合 A发送 Femtocell BS-A的全部或部分超帧头信息，且 Femtocell BS-A和 Macro BS-B 在子载波集合 A上的相关子载波上发送的内容相同。 由于 Macro BS-B 发送了 Femtocell BS-A 的超帧头， 则月艮务基站为 Femtocell BS-A的终端可以在接收 Femtocell BS-A的超帧头时获得宏分集增 益。 实施例 1 ~ 10中均以宏基站为例， 相关实施例同样适用于微基站、 毫基 站、 中继站等基站类型， 在此不再赘述。 实施例 1 ~ 10中均以超帧头为例，相关实施例同样适用于非用户专有控 制映射信息、 资源分配映射信息、 扩展广播信令等控制信息， 在此不再赘述。 优选地, 实施例 1 ~ 10中不同类型基站可以工作在相同的载频上。 综上所述， 通过本发明的上述实施例， 解决了不同类型基站之间控制信 息的千扰问题， 能够有效减少控制信息的覆盖盲区， 提高系统的服务质量。 显然， 本领域的技术人员应该明白， 上述的本发明的各模块或各步骤可 以用通用的计算装置来实现， 它们可以集中在单个的计算装置上， 或者分布 在多个计算装置所组成的网络上， 可选地， 它们可以用计算装置可执行的程 序代码来实现， 从而， 可以将它们存储在存储装置中由计算装置来执行， 或 者将它们分别制作成各个集成电路模块， 或者将它们中的多个模块或步骤制 作成单个集成电路模块来实现。 这样， 本发明不限制于任何特定的硬件和软 件结合。 以上所述仅为本发明的优选实施例而已， 并不用于限制本发明， 对于本 领域的技术人员来说， 本发明可以有各种更改和变化。 凡在本发明的 ^"神和 原则之内， 所作的任何修改、 等同替换、 改进等， 均应包含在本发明的保护 范围之内。
