Description

一种载波聚合实现方法、 装置与系统 技术领域
本发明涉及无线通信领域， 尤其涉及一种栽波聚合实现方法、 相应的基 站与移动终端以及一种载波聚合实现系统。 背景技术
3GPP长期演进技术（Long Term Evolution ， LTE )的后续增强版本称为 LTE-Advanced (简称 LTE-A ),其中引入了许多新的技术， 而载波聚合（ carrier aggregation )技术作为支持更高带宽传输的关键技术也被引入其中。 载波聚合 的基本原理是通过将两个或者更多的基本载波聚合在一起工作， 从而满足更 高的带宽需求。 引入载波聚合技术之后， 一个小区内的工作栽波数由一个变 为多个， 形成了多载波通信场景。 在 3GPP的 RANl#57bis会议上， 将这些载 波分为三类， 分别为：
1、 后向兼容栽波： LTE R8版本终端和 LTE-A终端都可以接入的载波， 而且 LTE-A终端还可以将该些载波作为聚合载波之一；
2、 LTE-A专属载波： LTE R8终端无法接入、 但 LTE-A终端可以接入的 载波， 而且 LTE-A终端可以将该些栽波作为聚合栽波之一；
3、 辅助栽波： LTE R8终端无法接入、 LTE-A终端可以在一定条件下接 入的载波。 接入条件为： 终端已经通过后向兼容栽波或者 LTE-A专属载波建 立通信连接， 而辅助载波只能在终端进行栽波聚合时作为额外的栽波使用。 即只有在两个及其以上载波建立起通信的终端才有可能使用了辅助载波， 而 只在一个载波上建立通信的终端所工作的这个栽波不可能是辅助载波。
目前， LTE-A分为时分复用 （ Time division duplex ， TDD )和频分复用 ( Frequency division duplex , FDD )两种工作模式。 相应地， 工作于 TDD模 式的移动终端称之为 TDD终端， 工作于 FDD模式的移动终端称之为 FDD终 端。 应用于 TDD工作模式的栽波称之为 TDD栽波， 应用于 FDD工作模式的 载波称之为 FDD栽波。
现有技术中， 对于如何实现栽波聚合， 目前还没有比较成熟的实现方案。 业界已提出有 TDD终端聚合 TDD载波， FDD终端聚合 FDD栽波的载波聚 合方式， 但具体实现方案还没有确定。 且无法实现不同模式的载波聚合， 即 不能实现 TDD终端聚合 FDD栽波， 以及不能实现 FDD终端聚合 TDD栽波。 发明内容
本发明实施例提供一种载波聚合实现方法， 相应的基站、 移动终端及载 波聚合实现系统， 实现 TDD终端和 FDD终端都能够聚合 TDD栽波和 FDD 载波。

图 3为本发明实施例提供的移动终端结构示意图。 具体实施方式
本发明实施例提供一种载波聚合实现方法， 使得 TDD终端和 FDD终端 都能够聚合 TDD载波和 FDD载波。
下面结合附图， 对本发明实施例提供的栽波聚合实现方法进行详细描述。 参见图 1， 为本发明实施例提供的载波聚合实现方法步骤流程图， 包括： 步骤 S101、 建立连接的移动终端接收基站发送的载波聚合控制信息。 载波聚合控制信息中包含作为下行工作载波聚合的目标栽波的栽波标识 以及目标载波的无线资源配置信息。
步驟 S102、 移动终端根据接收的载波标识和无线资源配置信息， 确定出 目标载波并侦听目标载波的下行控制信道。
步骤 S103、 移动终端解析出目标载波的下行控制信道上承栽的、 针对本 移动终端的小区 -无线网络临时标识（ Cell-Radio Network Temporary Identifier, C-RNTI ) 的下行控制信息。
步驟 S104、 移动终端根据解析出的 C-RNTI的下行控制信息， 从下行共 享信道中获取基站发送给本移动终端的下行数据。
下面对上述各步骤进行详细说明：
在步骤 S101之前， LTE-A的移动终端与基站建立起无线资源控制（ Radio Station Controller ， R C )连接， 进行通信。 其中， 对于 TDD终端接入 TDD 载波进行通信， 对于 FDD终端接入 FDD栽波进行通信。 当基站（eNB )配置 移动终端进行载波聚合操作时， 发送栽波聚合控制信息给移动终端， 要求移 动终端通过载波聚合来增加工作载波， 新增工作载波可以是下行 FDD载波， 也可以是下行 TDD载波。 在步骤 S101 中， 移动终端接收基站发送的载波聚 合控制信息， 在栽波聚合控制信息中， 包含作为下行工作载波聚合的目标载 波的载波标识以及目标载波的无线资源配置信息。 具体应用中， 目标载波的 载波标识以及目标载波的无线资源配置信息， 可以采用多种方式承载发送给 移动终端， 例如：
采用 RRC层控制信令承载目标载波的载波标识以及目标栽波的无线资源 配置信息时， 按照目前 3GPP 36.331中 R C控制信令格式制定的对应控制信 令可以包含：目标载波的频点、带宽、物理混合自动重传请求指示信道 ( physical HARQ indicator chanel ， PHICH )配置、 系统帧号（当目标栽波与移动终端 当前的工作载波帧同步时， 可以不包含系统帧号）、 侦听起始帧 （当釆用约定 的侦听间隔时长时， 也可以不包含侦听起始帧信息）和无线资源配置信息。 另一例子中， RRC控制信令可以包含： 目标载波的编号、 侦听起始帧和无线 资源配置信息。 其中无线资源配置包括： 下行共享信道配置、 上行控制信道 配置、 上行共享信道配置、 上行功率控制、 信道条件反馈 告配置、 天线情 况配置等等信息。 上述仅为举例， 还可以釆用其它的信令格式将目标载波的 载波标识以及目标载波的无线资源配置信息发送至移动终端， 本发明对此不 作限定。
同时， eNB 向移动终端发送载波聚合控制信息后， 会在规定的时间段内 在目标载波（下行 FDD载波或者 TDD载波）上调度该移动终端。 即在目标 载波的下行控制信道上发送系统信息 -无线网络临时标识（ system information - Radio Network Temporary Identifier , SI-RNTI )、 寻呼 -无线网络临时标识 ( paging - Radio Network Temporary Identifier, P-R TI )和针对移动终端的 小区 -无线网络临时标识（ Cell- Radio Network Temporary Identifier, C-RNTI )。 作为下行工作栽波聚合的目标载波并不需要做任何改变， 完全按照其本身工 作模式及 eNB的调度指示来承载相应的数据。即： 当目标载波采用 FDD栽波 时， 该作为下行工作载波聚合的 FDD栽波， 并不知道其承载的对应数据是发 送给 TDD终端还是发送给 FDD终端； 同理， 当目标载波采用 TDD载波时， 该作为下行工作载波聚合的 TDD载波， 也不知道其承载的对应数据是发送给 TDD终端还是发送给 FDD终端。
在步骤 S102中， 移动终端根据接收的载波标识和无线资源配置信息， 确 定出目标载波并侦听目标载波的下行控制信道。
移动终端启动侦听的方式可以有如下两种：
一种为显示指示方式： 在基站发送给移动终端的载波聚合控制信息中还 包含的侦听起始指示信息， 移动终端根据接收的侦听起始指示信息确定出侦 听起始时刻到达时， 启动侦听目标载波的下行控制信道。 其中， 侦听起始指 示信息可以是指示侦听间隔时长， 即指示移动终端在收到载波聚合控制信息 后间隔 X毫秒后开始侦听； 也可以指明侦听起始帧， 指示移动终端在侦听起 始帧的对应时刻开始启动侦听目标载波的下行控制信道。
另一种为隐式指示方式： 侦听间隔时长预先在基站与移动终端之间约定。 移动终端接收到基站发送的栽波聚合控制信息后， 确定出与基站预先约定的 侦听间隔时长到达时， 启动侦听目标载波的下行控制信道。
在步骤 S103中， 移动终端解析出目标载波的下行控制信道上承载的、 针 对本移动终端 C-RNTI的下行控制信息。 而对于 SI-RNTI和 P-RNTI的下行控 制信息则不做解析。 这样做， 保证了移动终端只是将目标载波作为辅助载波 使用。
在步骤 S104中， 移动终端根据解析出的 C-RNTI的下行控制信息， 从下 行共享信道中获取基站发送给本移动终端的下行数据。
本发明上述实施例提供的载波聚合实现方法中， 当目标载波的无线资源 配置信息发生变化时， 基站还将变化后的无线资源配置信息通知给移动终端， 以便移动终端根据变化后的无线资源配置情况正常接收数据。 将目标载波变 化后的无线资源配置信息通知给移动终端， 也可以通过 RRC控制信令承载。
当基站需要移动终端退出目标载波时， 只需要向移动终端发送携带目标 载波的载波标识的退出聚合载波指示信息， 该退出聚合载波指示信息也可以 通过 RRC控制信令承载， 或以其它的方式发送给移动终端。 移动终端接收到 基站发送的退出聚合栽波指示信息后， 停止侦听目标载波的下行控制信道。
基于同一发明构思， 本发明实施例还提供一种基站， 其结构示意图如图 2 所示， 包括：
