- Step S101 Determine another cooperating cell B having a multi-carrier cooperative function for the cell A.
- the cooperative cell B in the step S101 may be determined according to the cooperative cell information carried in the message sent by the base station. That is, the cooperable cell B can be determined by the base station and sent to the radio network control device by a message.
- the base station determines the cooperable cell, since the cooperating cell needs to use the same transmit antenna, the base station can use the cell on the base station that uses the same transmit antenna as the cell A and has the multi-carrier cooperative function as the cooperable cell.
- the local cell loca l ce l l
- the cell that can be paired with it is determined. Therefore, the base station can learn the cooperable cell of the cell A according to the configuration.
- the cooperable cell of the cell A may be further determined according to the frequency band in which the cell A should be in the same frequency band as the cooperating cell.
- the base station sends the information of the cooperating cell to the radio network control device, where the information about the cooperable cell B is added to the cell information, such as the cell audit and the radio sent by the NodeB to the RNC.

图 6示出了本发明实施例中的网络设备另一结构示意图。 具体实施方式
本发明实施例提供了一种多载波传输的方法和网络设备, 使小区间协作 的多载波服务成为了可能。
在多载波服务过程中, 主小区是用户设备(UE )接收广播消息或者控制 消息所在的小区。 本发明实施例首先需要为小区确立一个或者多个可协作小
区, 在激活这几个可协作小区的协作功能后, 为驻留在小区内的具有多载波 能力的用户提供多载波服务。
小区间的多载波协作关系可以由无线网络控制器 ( Radio Ne twork Control ler , RNC )或者基站来控制,也可以由 RNC和基站协商控制。具体的, 多载波服务可以使 UE同时接收两个小区的高速下行控制物理信道,两个小区 属于相同的 NodeB, 并且在相邻的载波上同时工作在一个频段内的不同频率 上。
图 1示出了本发明实施例中的多载波传输方法的第一流程图, 包括如下 步骤:
步骤 S101 : 为小区 A确定其他具有多载波协作功能的可协作小区 B。 该步骤 S101中的可协作小区 B, 具体可以根据基站发送的消息中携带的 可协作小区信息确定。 也就是说, 该可协作小区 B可以由基站确定, 并通过 消息发送给无线网络控制设备的。
基站在确定可协作小区时, 由于可协作小区需要使用相同的发射天线, 因此基站可以将基站上与小区 A使用相同发射天线、 且具有多载波协作功能 的小区作为可协作小区。 还有一种情况是, 在配置本地小区 (loca l ce l l ) 时, 就已确定了可以与其配对的小区, 因此, 基站可以根据该配置获知小区 A的可协作小区。
在本步骤中, 还可以根据小区 A应与可协作小区使用的频段位于同一个 频段, 来进一步确定小区 A的可协作小区。
基站将可协作小区的信息发送给无线网络控制设备, 具体可以是在小区 信息中增加可协作小区 B的信息, 如在 NodeB发送给 RNC的小区审计和无线
资源指示的信息中增加该小区 A可进行协作的可协作小区 B的信息。 通过该 设置, RNC (无线网络控制器)就知道了基站(NodeB )上能和此小区 A进行 多载波协作功能的可协作小区 B的信息。 是否激活这个可协作小区 B的多载 波协作功能可以由 RNC决定。
步骤 S102 : 激活上述具有多载波协作功能的可协作小区 B的小区协作特 性, 为驻留在小区 A的具有多载波能力的用户设备提供多载波服务。
具体的, 可以是 RNC通过向 NodeB发送小区重配置或系统广播信息或者 单独的小区协作关系建立信令, 来通知可进行多载波协作的可协作小区 B建 立小区协作关系, 并通过小区协作关系为用户设备提供多载波服务。 具体的, RNC从确定的可协作小区中选择至少一个, 通知 NodeB激活所选择的可协作 小区 B, 以及通知基站建立所述小区 A与所选择的可协作小区 B之间的协作 关系; 或 RNC通知 NodeB激活所确定的具有多载波功能的可协作小区 B , 以 及通知 NodeB建立所述小区 A与所确定的可协作小区 B之间的协作关系; 或 RNC通知 NodeB同时建立所述小区 A及所述可协作小区 B,以同时激活所述小 区 A及所述可协作小区 B, 以及通知基站建立所述小区及可协作小区的协作 关系。
需要说明的是, 这里的小区间的协作关系可以是相互的, 如小区 B为小 区 A的可协作小区时, 小区 A也可以是小区 B的可协作小区。
相应的, 图 2示出了本发明实施例中的多载波传输方法的第二流程图, 包括如下步骤:
步骤 S201 : 基站向无线网络控制器发送可协作小区信息;
在小区投入运营前一般是通过本地小区标识(loca l ce l l ID ) 来标识小
区资源的, 在小区投入运营后通过小区标识(cell ID) 来标识小区资源的。 这里可以在本地小区 (local cell ) 小区信息中增加可协作小区的信息, 该 可协作小区具有多载波协作功能, local cell作为 NodeB上的无线资源, 对 应的物理资源已经确定,需要与相同发射天线的可协作小区完成多载波服务。 在发送给 RNC的小区审计和无线资源指示的消息中增加此 local cell的可协 作小区的信息, 该信息可以是本地小区标识(local cell ID) , 也可以是小 区标识(Cell ID) 。 当然, 如果可以是多小区协作, 则此信息可包含多个可 协作小区的信息。
步骤 S202: 确定小区的协作关系并激活;
根据步骤 S201返回的信息, RNC可以根据该返回的可协作小区信息决定 是否启动协作关系, 如果可协作小区为多个, 则还可确定和哪个 /哪些小区启 动协作。 由于 NodeB返回了小区信息, RNC控制着小区频率, 这里 RNC可以 根据小区分配的频率等来决定。
如 RNC决定激活小区的协作功能, 比如, RNC决定小区(Cell ) 2与 Cell 1进行协作, RNC需要通知 NodeB: Cell 1需要和 Cel 12进行协作, 可以通 过小区重配置(Cell Reconfiguration)和 /或系统广播消息更新来指示 Cell 1和 Cell 2建立小区协作关系。 具体的, RNC可以针对两个小区分别向 NodeB 发送消息, 请求 Cell 1和 Cell2建立协作关系; 由于可以和一个小区 A具有 协作关系的各个其他小区在该小区 A产生的时候就已经确定, 即 NodeB可以 知道该小区 A的协作关系, RNC也可以针对一个小区向 NodeB发送消息, NodeB 则根据该消息以及该小区与另一小区的协作关系, 从而激活另一小区, 即这 里的 NodeB也可以才艮据 Cell 1和 Ce 11 2的协作关系, 当 Ce 11 2激活同时协
作关系也激活时, 自动为 Cell 1 和 Cell 2建立协作关系, 并更新 Cell 1 的协作关系列表和广播。
RNC 可以通过一条专门的信令, 如增加小区协作功能激活 ( Cell Cooperation Function Active ) , 也可以通过小区重配置和系统广播消息更 新来指示两个小区开启协作功能并指示可协作小区。 通过激活该协作功能, 即可实现多载波服务。
步骤 S203: 更新小区的协作关系。
如果小区之间的协作关系发生变化, 也需要更新。
若需要取消多载波月良务时, 可以由 RNC发起小区去激活, 对应的小区协 作关系解除,取消多载波服务功能。具体的,可以通过 RNC向 NodeB发送 Cell Reconfiguration 和 /或系统广播消息更新来指示, 当一个小区去激活时, NodeB 自动解除两个小区的协作关系, 也可以通过一条专门的信令(在 lub 或者 Iur接口上) , ^口增力口小区协作功能激活 ( Cell Cooperation Function Active ) 来指示。
图 3示出了本发明实施例中的多载波传输方法的第三流程图, 包括如下 步骤:
步骤 S301: 基站向无线网络控制器发送可协作小区信息;
与前面的步骤 S201类似, 当一个 local cell配置时, 就已经确定了可 以与其协作的小区, 在小区信息中包含能够与此小区协作的可协作小区的信 息, 可以是小区的 local cell ID, 也可以是小区的 cell ID, RNC可以才艮据 小区审计和无线资源指示的消息获得这一信息。
步骤 S302: 确定小区协作关系并激活;
与前面的步骤 S202类似, 该激活过程可以由 RNC来激活, 即 RNC通知 NodeB激活所确定的具有多载波功能的可协作小区,以及通知 NodeB建立 Cell 1和 Ce 112之间的协作关系。 小区的协作关系在小区产生的时候就已经确定, 在 Cell 1建立时, RNC 如果支持小区协作, 同时 cell 1小区的资源消息中 有可以协作的小区 Cell2 (这个小区已经投入运营), 这样就需要激活 Cell 1 和 Cell 2的协作功能。 RNC可以在小区一建立的时候就启动其和 Cell 2的 协作功能, 对于 Cell 2, RNC通过小区重配置来设置 Cell 2的小区协作功能。 NodeB也可以才艮据两小区固定的协作关系,在小区 1建立的同时, 自动为 Cell 1和 Cell 2建立协作关系。
步骤 S303: 更新小区协作关系。
如果可协作小区中有一个小区去激活, 则另一个小区的协作功能也需要 去除, 可以通过专门的信令, 也可以通过小区重配置消息来去激活。
图 4示出了本发明实施例中的多载波传输方法的第四流程图, 包括如下 步骤:
步骤 S401: 基站向无线网络控制器发送可协作小区信息;
同步骤 S30L
步骤 S402: 确定小区协作关系并激活;
与前述步骤 S302类似。 另外, RNC可以通知 NodeB同时建立 Cell 1和 Cell 2, 以及同时激活 Celll和 Cell 2, 以及通过 NodeB建立 Cel 11和 Cel 1 2 的协作关系。 当激活小区协作功能时, 两个或者多个进行协作关系的小区 必须同时激活。 而现有的小区建立消息只是针对单小区的, 同时只能激活一 个小区。这就需要在现有的小区建立消息中同时可以建立两个或者多个小区,
增加可协作小区的信息, 同时激活或者是同时建立这几个有协作关系的小区。 步骤 S403 : 更新小区协作关系。
如果可协作小区中有一个小区去激活, 则另一个小区的协作功能也需要 去除, 可以通过专门的信令, 也可以通过小区重配置消息进行。 可能需要重 配置消息支持多小区同时进行重配置的操作。
上述实施方案主要以 RNC控制完成可协作小区激活,在具体实施过程中, 也可以通过 NodeB控制完成可协作小区的激活, 具体实现过程与上述方案相 同, 即同样通过为小区确立多载波协作能力的可协作小区, 激活该可协作小 区的多载波协作能力为 UE提供多载波服务, 从而实现了多载波服务。
