Description

传输终端能力的方法、 重定位、 系统间切换方法及系统
技术领域
本发明涉及通信技术领域, 更具体地, 涉及一种传输终端能力的方法、 重定位、 系统间切换方法及系统。
背景技术
在 R7 阶段, 通用移动通讯系统 ( Universal Mobile Telecommunications System, 简称 UMTS ) 引入了多输入多输出 ( Multiple-Input Multiple-Output, 简称 MIMO )技术。 在 R8阶段, 引入了双载波( Dual Carrier, 简称 DC ) , 但 UE ( User Equipment, 用户设备 )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, 并利用双载波小区 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。但对于不同的 UE, 其支持的下行 载波数与可配置为 MIMO的下行载波个数并不一致。 比如有的 UE支持下行 载波数最大配置为 4, 但在使用多载波的时候, 其无法使用 MIMO; 有的 UE 支持下行载波数最大配置为 3 , 但在使用多载波的时候, 只有一个下行载波 支持配置为 MIMO。
目前协议已有的双载波小区 MIMO支持( Dual cell MIMO support )信元 不能够表示出 UE在支持多载波的时候, 其支持配置为 MIMO的下行载波的 最大个数。 这样, 网络侧不能准确地为 UE配置 MIMO参数, 从而无法合理 分配资源。 例如, 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, 网络侧通常也不会给 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, 无法有效的提高下行传输速率。
综上所述, 现有技术存在如下技术问题: 1 )网络侧无法准确地获知 UE支持多载波能力,即 UE支持配置为 MIMO 的下行载波个数的能力, 因此, 不能准确地为 UE配置 MIMO参数, 从而无 法合理分配资源;
2 ) 当 UE在两个 RNC ( Radio Network Controller, 无线网络控制器 )之 间进行重定位, 包括 UE相关的重定位、 UE无关的重定位时, 重定位或者目 标网络侧无法获知 UE支持配置为 MIMO的下行载波个数的能力, 进而无法 合理分配资源。
3 ) 当 UE发生系统间切换时, 目标网络侧也需要获知 UE 支持配置为 MIMO的下行载波个数的能力, 从而为 UE合理分配资源。

本发明的目的之一在于, 提供一种解决方案, 使网络侧能够获知 UE支 持配置为 MIMO的下行载波个数的能力, 并依此合理分配资源。
为达到上述目的, 本发明的核心思想为: 提供一种传输 UE支持配置为 MIMO的下行载波个数的能力的技术方案, 当 UE支持多载波时, 将支持多 载波的 UE支持配置为 MIMO的下行载波个数的能力携带在与 RNC的交互消 息中发送给 RNC; RNC根据收到的来自 UE的交互消息获取 UE的支持配置 为 MIMO的下行载波个数的能力。 其中, RNC与 UE之间通过 Uu口进行消 息交互, 因此 RNC与 UE之间交互消息, 也称为 Uu口消息。
进一步地, 传输 UE支持配置为 MIMO的下行载波个数的能力的方式可 以有多种, 包括但不限于以下几种:
1、 在无线资源控制连接请求( RRC Connection Request )消息中增设 UE 支持配置为 MIMO的下行载波个数的能力的指示信元,在 UE支持多载波时, 将该指示信元携带在 RRC Connection Request消息中发送给 RNC;
2、 在无线资源控制连接请求( RRC Connection Request )消息中增设 UE 支持配置为 MIMO的下行载波个数的能力的指示信元, 在 UE支持多载波, 且 UE支持配置为 MIMO的下行载波个数为 3个、 4个时, 将该指示信元携 带在 RRC Connection Request消息中发送给 RNC;
3、对 R8协议中 UE支持双载波和 MIMO能力的 Dual cell MIMO support 信元取值进行扩展, 扩展后的取值用以表示 UE支持配置为 MIMO的下行载 波个数的能力; 在 UE支持多载波时, 将扩展的信元携带在 RRC Connection Request消息中发送给 RNC;
4、 对高速下行共享传输信道物理层类别 (HS-DSCH physical layer category )的等级进行扩展, 附加上 UE支持配置为 MIMO的下行载波个数的 能力等级; 在 UE支持多载波时, 将扩展的 HS-DSCH physical layer category 携带在无线资源控制连接建立完成( RRC Connection Setup Complete ) 消息、 或 UE能力信息 ( UE Capability Information ) 消息中发送给 RNC;
5、 在无线资源控制连接请求(RRC Connection Request ) 消息中增设一 可以同时表示 UE支持多载波的能力和支持配置为 MIMO的下行载波个数能 力的指示信元,在 UE支持多载波时,将所述指示信元携带在 RRC Connection Request消息中发送给所述 RNC。
下面将结合附图及具体实施例对上述传输 UE支持多载波能力的方法作 进一步详细阐述。
实施例一
本实施例中,通过在 RRC Connection Request消息中增加一个 UE支持配 置为 MIMO 的下行载波个数能力的指示信元, 用以指示 UE 的支持配置为 MIMO的下行载波个数能力。
本实施例中, 该指示信元可以为多 MIMO支持( Multi MIMO Support ) 信元。
如图 1所示, 本实施例的传输 UE支持多载波能力的方法描述如下: 支持多载波能力的 UE, 在发送给 RNC的 RRC Connection Request消息 中包含 Multi MIMO Support信元, 表示 UE支持配置为 MIMO的下行载波个 数;
RNC对接收的 RRC Connection Request消息进行解析, 并根据消息中的 Multi MIMO Support信元可以获知发送消息的 UE支持配置为 MIMO的下行 载波个数。
本实施例中, Multi MIMO Support信元的协议描述如下表 1所示:
表 1 多 MIMO支持信元协议描述
Figure imgf000014_0001
Group name description
Multi MIMO Support OP Enumerated( Single , The absence of this Dual, Three, Four ) IE indicates that the
UE does not support Multi carrier with MIMO 参见表 1 , 该 Multi MIMO Support指示信元的具体实施如下:
如果 UE支持配置为 MIMO的下行载波的个数为 0, 则 UE不携带 Multi MIMO Support信元;
如果 UE支持配置为 MIMO的下行载波的个数为 1 ,则 UE将 Multi MIMO Support信元设置为 Single, 实际取值为 0;
如果 UE支持配置为 MIMO的下行载波的个数为 2,则 UE将 Multi MIMO Support信元设置为 Dual , 实际取值为 1;
如果 UE支持配置为 MIMO的下行载波的个数为 3 ,则 UE将 Multi MIMO Support信元设置为 Three , 实际取值为 2;
如果 UE支持配置为 MIMO的下行载波的个数为 4,则 UE将 Multi MIMO
Support信元设置为 Four, 实际取值为 3。
RNC对接收的 RRC Connection Request消息进行解析, 并根据消息中的 Multi MIMO Support信元的取值,可以获知发送消息的 UE支持配置为 MIMO 的下行载波个数能力。
如果 UE 不支持多载波时, 则 UE在发送给 RNC 的 RRC Connection
Request消息中不包含 Multi MIMO Support信元。
实施例二
本实施例中,通过在 RRC Connection Request消息中增加一个 UE支持配 置为 MIMO 的下行载波个数能力的指示信元, 用以指示 UE 的支持配置为 MIMO的下行载波个数能力。 本实施例中,该指示信元可以为双小区 MIMO支持扩展( Dual cell MIMO support extension )信元, 表示 UE支持配置为 MIMO的下行载波个数。
如图 2所示, 本实施例的传输 UE支持多载波能力的方法描述如下: 支持多载波能力的 UE, 其支持配置 MIMO的下行载波个数为 3个、 4 个时, 在发送给 RNC的 RRC Connection Request消息中包含 Dual cell MIMO support extension信元。
RNC对接收的 RRC Connection Request消息进行解析, 并根据消息中的 Dual cell MIMO support extension信元可以获知发送消息的 UE支持配置为 MIMO的下行载波个数。
本实施例中, Dual cell MIMO support extension信元的协议描述如下表 2 所示:
表 2 多 MIMO支持扩展信元协议描述
Figure imgf000016_0001
参见表 2,该 Dual cell MIMO support extension指示信元的具体实施如下: 如果 UE支持配置为 MIMO的下行载波的个数为 3 , 则 UE将 Dual cell MIMO support extension信元设置为 Three, 实际取值为 0;
如果 UE支持配置为 MIMO的下行载波的个数为 4, 则 UE将 Dual cell MIMO support extension信元设置为 Four, 实际取值为 1。
RNC对接收的 RRC Connection Request消息进行解析, 并根据消息中的 Dual cell MIMO support extension信元的取值, 可以获知发送消息的 UE支持 配置为 MIMO的下行载波个数能力。 如果 UE 不支持多载波时, 则 UE在发送给 RNC 的 RRC Connection Request消息中不包含 Dual cell MIMO support extension信元; UE支持多载波, 但是支持配置 MIMO的下行载波数小于等于 2个时, UE在发送给 RNC的 RRC Connection Request消息中也不包含 Dual cell MIMO support extension信 元。
实施例三
本实施例中, 对 RRC Connection Request消息中的双载波小区 MIMO支 持(Dual cell MIMO support )信元的取值进行扩展, 通过 Dual cell MIMO support信元的扩展取值来指示 UE的支持多载波能力。
如图 3所示, 本实施例的传输 UE支持多载波能力的方法描述如下: 支持多载波能力的 UE, 在发送给 RNC的 RRC Connection Request消息 中包含 Dual cell MIMO support信元,取值为 UE支持配置为 MIMO的下行载 波个数;
RNC对接收的 RRC Connection Request消息进行解析, 并根据消息中的
Dual cell MIMO support信元可以获知发送消息的 UE支持配置为 MIMO的下 行载波个数。
本实施例中, Dual cell MIMO support信元的协议描述如下表 3所示: 双载波小区 MIMO支持信元协议描述
Figure imgf000017_0001
参见表 3 , 该 Dual cell MIMO support信元的具体实施如下: 如果 UE支持配置为 MIMO的下行载波个数为 0,则 UE不携带 Dual cell MIMO support信元;
如果 UE支持配置为 MIMO的下行载波个数为 1 ,则 UE将 Dual cell MIMO support信元设置为 Single, 实际取值为 1 ;
如果 UE支持配置为 MIMO的下行载波个数为 2,则 UE将 Dual cell MIMO support信元设置为 Dual , 实际取值为 0;
如果 UE支持配置为 MIMO的下行载波个数为 3 ,则 UE将 Dual cell MIMO support信元设置为 Three , 实际取值为 2;
如果 UE支持配置为 MIMO的下行载波个数为 4,则 UE将 Dual cell MIMO support信元设置为 Four, 实际取值为 3。
RNC对接收的 RRC Connection Request消息进行解析, 并根据消息中的 Dual cell MIMO support信元的取值, 可以获知发送消息的 UE支持配置为 MIMO的下行载波个数能力。
如果 UE不支持多载波, 但支持双载波同时配置 MIMO时, 也携带 Dual cell MIMO support信元(在此种情况下, 协议原有处理是枚举 true, 实际的 取值是 0 ) 。 在 UE支持多载波时, 且支持配置为 MIMO的下行载波数为 2 时, Dual cell MIMO support的信元取值为 Dual, 实际取值为 0 ) 。
实施例四
在实施例中, 通过在 RRC Connection Request消息中增加一个同时表示
UE支持多载波和支持配置为 MIMO的下行载波个数能力的指示信元, 用以 同时指示 UE的支持多载波能力和支持配置为 MIMO的下行载波个数能力。
该指示信元可以为多载波和 MIMO 支持 (Multi Carrier And MIMO Support )信元。
如图 4所示, 本实施例的传输 UE支持多载波能力的方法描述如下: 支持多载波能力的 UE, 在发送给 RNC的 RRC Connection Request消息 中包含 Multi Carrier And MIMO Support信元, 用以同时指示 UE的支持多载 波和支持配置为 MIMO的下行载波个数能力, 该信元的取值如表 5中第一列 的一个索引值所示, UE根据其支持配置高速下行载波个数和支持配置为 MIMO的下行载波个数在表 5中查询得到 Multi Carrier And MIMO Support对 应的索引值。
RNC对接收的 RRC Connection Request消息进行解析, 并根据消息中的 Multi Carrier And MIMO Support信元可以获知发送消息的 UE支持配置为 MIMO的下行载波个数。
本实施例中, Multi Carrier And MIMO Support信元的协议描述如下表 4 所示:
表 4 Multi Carrier And MIMO Support信元的协议描述
Figure imgf000019_0001
其中, Multi Carrier And MIMO Support的取值对应 UE支持的多载波能 力和支持配置为 MIMO的下行载波个数能力, 如下表 5所示:
表 5 Multi Carrier And MIMO Support的取值规则
Figure imgf000019_0002
7 4 3
8 4 4 如果 UE不支持多载波,则 UE在发送给 RNC的 RRC Connection Request 消息中不包含 Multi Carrier And MIMO Support信元。
实施例五
本实施例中, 对 HS-DSCH物理层类别 ( physical layer category ) 的等级 进行扩展, 附加上 UE支持多载波和 MIMO的能力等级, 比如 UE支持四个 多载波且 4个下行载波都可以配置为 MIMO的能力等级。
如图 5所示, 本实施例的传输 UE支持多载波能力的方法描述如下: 如果 UE支持多载波和 MIMO能力, 则 UE在发送给 RNC的 RRC连接 建立完成(RRC Connection Setup Complete ) 消息中包含扩展的 HS-DSCH physical layer category, 且 HS-DSCH physical layer category的扩展等级用以指 示 UE的支持多载波能力和支持配置为 MIMO的下行载波个数能力;
RNC对接收的 RRC连接建立完成消息进行解析, 并根据消息中包含的 扩展 HS-DSCH physical layer category可以获知发送消息的 UE支持配置为 MIMO的下行载波个数。
其中, 所谓扩展 HS-DSCH physical layer category, 是指增力。 category的 取值, 在目前的 R9协议中, category的取值已经扩展到了 28, 那么本发明中 的 category可以取大于 28的值来表示 UE支持多载波和支持配置为 MIMO的 下行载波个数的能力。
下表 6示出了该 category的取值对应的取值对应 UE支持多载波和支持 配置为 MIMO的下行载波个数的能力的索引:
HS-DSCH physical layer category的取值索引

31 3 2
32 3 3
33 4 0
34 4 1
35 4 2
36 4 3
37 4 4
实施例六
本实施例与上述实施例五相似, 同样是对 HS-DSCH physical layer category的等级进行扩展, 附加上 UE支持多载波和支持配置为 MIMO的下 行载波个数的能力等级, 与实施例五不同的是, 如图 6所示, 本实施例中是 通过 UE能力信息( UE Capability Information ) 消息将 UE支持多载波和支持 配置为 MIMO的下行载波个数能力告知 RNC。
如图 6所示, 如果 UE支持多载波能力, 则 UE在发送给 RNC的 UE Capability Information消息中包含扩展的 HS-DSCH physical layer category, 且 HS-DSCH physical layer category的扩展等级用以指示 UE的支持多载波和支 持配置为 MIMO的下行载波个数能力, 具体如何指示与实施例四中相同, 此 处不再赘述。
