Description

一种支持多载波 MIMO能力的通知方法和装置 技术领域
本发明涉及通信领域，具体涉及一种支持多载波多输入多输出（ MIMO, Multiple-Input Multiple-Output ) 能力的通知方法和装置。 背景技术
在 R7阶段， WCDMA系统引入了多输入多输出（ MIMO , Multiple-Input Multiple-Output ), 在 R8 阶段， 引入了 DC 双载波， 但用户设备 ( User Equipment, UE ) 不同时支持 MIMO和 DC双载波； 在 R9阶段， UE可以 同时支持 MIMO和 DC双载波， 利用双载波小区 MIMO支持（Dual cell MIMO support )信元来表示 UE在支持多载波的同时是否支持 MIMO, 这 些特性的引入， 都极大的提高了传输速率。 为了进一步提高用户峰值速率， 需要将更多的载波组合在一起进行传输， 同时， 每条下行载波上都可以配 置 MIMO, 但不同的小区所支持的下行载波数与可配置为 MIMO的下行载 波个数并不一致， 比如有的基站 （Node b ) 小区支持下行载波数最大配置 为 4, 但在使用多载波时无法使用 MIMO, 有的 Node b小区支持下行载波 数最大配置为 3 , 但在使用多载波时只有一个下行载波支持配置为 MIMO。
目前协议已有的表示 Node b小区 MIMO能力和多载波能力信元，不能 够表示出 Node b小区在支持多载波时支持配置为 MIMO的下行载波个数， 因此网络侧无法准确给 UE配置 MIMO参数， 不能合理分配资源。 即使 UE 支持下行载波数最大配置为 4,且下行 4个载波都可以配置为 MIMO,但按 照目前协议的处理， 在网络资源充分够用的情况下， 网络侧也无法给 UE 在 4个下行载波上都配置 MIMO, 也就无法合理充分分配资源， 无法有效 提高下行传输速率。 发明内容
有鉴于此， 本发明的主要目的在于提供一种支持多载波 MIMO能力的 通知方法和装置，针对支持多载波的 Node b小区，指示其支持配置为 MIMO 的下行载波个数， 促进资源的合理分配。

本发明的支持多载波 MIMO能力的通知方法和装置， 使得网络侧能够 获知 Node b小区支持配置为 MIMO的下行载波个数，进而能够依据所获知 的支持配置为 MIMO的下行载波个数合理分配资源。 附图说明

图 8为本发明实施例一的支持多载波 MIMO能力的通知装置图。 具体实施方式
总体而言， 当 Node b小区支持多载波时， 所述 Node b将支持配置为 MIMO 的下行载波个数携带在与无线网络控制器 （ RNC , Radio Network Controler )的交互消息中发送给 RNC。 RNC对来自 Node b的交互消息进行 解析， 获取其中的 Node b小区支持配置为 MIMO的下行载波个数。
具体而言， Node b将自身的支持配置为 MIMO的下行载波个数携带在 与 RNC的交互消息中发送给 RNC的方法有多种， 如：
方法一： 在审计响应 （ AUDIT RESPONSE ) 消息中扩展小区能力容器 ( Cell Capability Container )信元的第十二 bit到第十五 bit共计 4bit, 作为 指示信元， 用以指示 Node b小区的支持配置为 MIMO的下行载波个数。如 果所述 Node b 小区支持多载波， 则将所述指示信元携带在 AUDIT RESPONSE消息中并发送给 RNC。 Cell Capability Container的协议描述如 表 1所示：

MIMO的最大载波数， 釆用 2进制编码。 第十二位是最 高有效位， 第十五位是最低 有效位。 0表示在多载波时， 不支持同时配置 MIMO 表 1
方法二： 在 AUDIT RESPONSE 消息中新增支持辅助服务小区配置 MIMO 的最大载波数能力 （ Max No. of Secondary Cell with MIMO Capability )信元， 作为表示 Node b小区支持配置为 MIMO的辅助下行载 波个数的指示信元，用以指示 Node b小区的支持配置为 MIMO的辅助下行 载波个数及其对应的辅助小区。 如果所述 Node b小区支持多载波， 则将所 述指示信元携带在 AUDIT RESPONSE消息中并发送给 RNC。 Max No. of Secondary Cell with MIMO Capability的协议描述如表 2所示：
Figure imgf000007_0001
Figure imgf000008_0001
表 2 方法三： 在 AUDIT RESPONSE消息中新增多载波小区 MIMO全支持 ( Multi Cell All MIMO Support )指示信元， 用于表示该 Node b小区在配置 多载波时， 本小区及其辅助小区的所有载波都支持同时配置 MIMO。 如果 所述 Node b小区支持多载波，则将所述指示信元携带在 AUDIT RESPONSE 消息中并发送给 RNC。 如果支持本小区及其辅助小区的所有载波同时都配 置 MIMO , 则取值为全支持 MIMO ( All MIMO Support ) , 否则取值为全不 支持 MIMO ( All MIMO Not Support )。 Multi Cell All MIMO Support的协议 描述如表 3所示：
Figure imgf000008_0002
表 3
由以上操作思路可见， Node b能够在支持多载波时， 将自身的支持配 置为 MIMO的下行载波个数携带在与 RNC的交互消息中并发送给 RNC; RNC则能够对来自 Node b的交互消息进行解析， 获取 Node b支持配置为 MIMO的下行载波个数。
具体而言， Node b可以在 AUDIT RESPONSE消息中扩展 Cell Capability Container信元的第十二 bit到第十五 bit共计 4bit, 作为指示信元， 用以指 示 Node b小区的支持配置为 MIMO的下行载波个数。 如果所述 Node b小 区支持多载波，则将所述指示信元携带在 AUDIT RESPONSE消息中并发送 给 RNC。 再有， Node b还可以在 AUDIT RESPONSE消息中新增 Max No. of Secondary Cell with MIMO Capability信元， 作为表示 Node b小区支持配置 为 MIMO的辅助下行载波个数的指示信元，用以指示 Node b小区的支持配 置为 MIMO的辅助下行载波个数及其对应的辅助小区。如果所述 Node b小 区支持多载波，则将所述指示信元携带在 AUDIT RESPONSE消息中并发送 给 RNC。
另外， Node b也可以在 AUDIT RESPONSE消息中新增 Multi Cell All MIMO Support指示信元， 用于表示该 Node b小区在配置多载波时， 本小 区及其配置的辅助小区的载波支持同时配置 MIMO。 如果所述 Node b小区 支持多载波，则将所述指示信元携带在 AUDIT RESPONSE消息中并发送给 RNC。 如果支持本小区及其辅助小区的所有载波同时都配置 MIMO , 则取 值为 All MIMO Support, 否则取值为 All MIMO Not Support。
下面结合附图和具体实施例对本发明的技术方案进一步详细阐述。 参见图 1所示的实施例一， 当小区支持配置为 MIMO的下行载波个数 为 4(即除支持本小区配置 MIMO以夕卜，还可另外配置 3个同时配置 MIMO 的辅助小区） 时， 支持多载波能力的 Node b 在发送给 RNC 的 AUDIT RESPONSE消息中携带 Cell Capability Container信元，且第十二 bit取值为 0, 第十三 bit取值为 1 , 第十四 bit取值为 0, 第十五 bit取值为 0; RNC对 接收的 AUDIT RESPONSE消息进行解析， 并根据消息中的 Cell Capability Container信元的第十二到第十五 bit可以获知发送消息的 Node b小区支持 配置为 MIMO的下行载波个数为 4。
参见图 2所示的实施例二， 当小区支持配置为 MIMO的下行载波个数 为 3 (即除支持本小区配置 MIMO以外，还可另外配置 2个同时配置 MIMO 的辅助小区） 时， 支持多载波能力的 Node b 在发送给 RNC 的 AUDIT RESPONSE消息中携带 Cell Capability Container信元，且第十二 bit取值为 0, 第十三 bit取值为 0, 第十四 bit取值为 1 , 第十五 bit取值为 1 ; RNC对 接收的 AUDIT RESPONSE消息进行解析， 并根据消息中的 Cell Capability Container信元的第十二到第十五 bit可以获知发送消息的 Node b小区支持 配置为 MIMO的下行载波个数为 3。
参见图 3所示的实施例三， 当小区支持配置为 MIMO的下行载波个数 为 4(即除支持本小区配置 MIMO以外，还可另外配置 3个同时配置 MIMO 的辅助小区） 时， 支持多载波能力的 Node b 在发送给 RNC 的 AUDIT RESPONSE消息中携带 Max No. of Secondary Cell with MIMO Capability信 元，且设置 Max No. of Secondary Cell with MIMO Capability的取值为 3 ,可 能辅助服务小区列表（Possible Secondary Serving Cell List )对应支持的 3 个小区 ID。
参见图 4所示的实施例四， 当小区支持配置为 MIMO的下行载波个数 为 3 (即除支持本小区配置 MIMO以外，还可另外配置 2个同时配置 MIMO 的辅助小区） 时， 支持多载波能力的 Node b 在发送给 RNC 的 AUDIT RESPONSE消息中携带 Max No. of Secondary Cell with MIMO Capability信 元， 且设置 Max No. of Secondary Cell with MIMO Capability的取值为 2, Possible Secondary Serving Cell List对应支持的 2个小区 ID。
参见图 5所示的实施例五， 当小区支持配置为 MIMO的下行载波个数 为 0 (即不支持本小区配置 MIMO, 也不支持其他的辅助小区配置 MIMO ) 时，支持多载波能力的 Node b在发送给 RNC的 AUDIT RESPONSE消息中 不包含 Max No. of Secondary Cell with MIMO Capability信元。
参见图 6所示的实施例六， 当小区支持配置的多载波个数为 4 (即除支 持本小区配置 MIMO以外， 还可另外配置 3个同时配置 MIMO的辅助小 区）， 并且配置的 4个载波都支持同时配置 MIMO时， 支持多载波能力的 Node b在发送给 RNC的 AUDIT RESPONSE消息中携带 Multi Cell All MIMO Support信元， 且 Multi Cell All MIMO Support的取值为 All MIMO Support。
由以上实施例可知， 在进行本发明支持多载波 MIMO能力的通知操作 时， 总体的操作思路可以表示如图 7所示。 参见图 7 , 图 7为本发明支持多 载波 MIMO能力的通知流程简图， 该流程包括以下步骤：
步骤 710: 支持多载波时， 在用于上报小区能力的消息格式中指示出支 持配置为 MIMO的下行载波个数。
具体而言， 用于上报小区能力的消息格式可以是前述的 AUDIT RESPONSE, 也可以是其它的通知消息等。
步骤 720: 上报指示出所述支持配置为 MIMO的下行载波个数的消息 格式。
具体而言， 上报的主体除了可以是前述的 Node b以外， 也可以是接入 网中的中继站或用户侧的其它设备。 并且， 接收所述消息格式的主体除了 可以是前述的 RNC以外， 也可以是操作维护中心（OMC )等其它用于进行 资源或用户管理的设备。
为了实现上述各流程图中的操作， 可以设置如图 8所示的装置。 参见 图 8, 图 8为本发明实施例一的支持多载波 MIMO能力的通知装置图， 该 装置可以设置于 Node b或接入网中的中继站或用户侧的其它设备中， 包括 相连的消息格式扩展单元、 消息格式上报单元。 其中， 消息格式扩展单元 能够在支持多载波时， 在用于上报小区能力的消息格式中指示出支持配置 为 MIMO的下行载波个数， 并将上述指示情况通知给消息格式上报单元。 消息格式上报单元能够根据消息格式扩展单元通知的指示情况， 上报指示 出所述支持配置为 MIMO的下行载波个数的消息格式。
当然， 在此之后， RNC等所述消息格式的接收方还能够接收上报的消 息格式， 从中解析出支持配置为 MIMO的下行载波个数， 根据解析出的下 行载波个数分配资源。
上述各单元所能实现的具体操作已在前述流程中详细描述， 在此不再 赘述。
综上所述可见， 无论是方法还是装置， 本发明的支持多载波 MIMO能 力的通知技术，使得网络侧能够获知 Node b小区支持配置为 MIMO的下行 载波个数， 进而能够依据所获知的支持配置为 MIMO的下行载波个数合理 分配资源。
以上所述仅为本发明的优选实施例， 并非因此限制本发明的专利范围， 凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换， 或直 接或间接运用在其他相关的技术领域， 均同理包括在本发明的专利保护范 围内。
