(增强前向接入信道) 等特性的引入, Cell_FACH (Cell Forward Access Channel, 小区 前向接入信道)状态可以承载的业务越来越多, 因此提高 Cell_FACH状态的下行峰值速 率成为当前需要解决的问题之一。 然而, 现有技术中 64QAM 的配置方法仅仅适用于 Cell_DCH状态的 UE, 由于当前并不存在针对 Cell_FACH状态 UE的专用信令, 因此采 用现有技术无法完成 Cell_FACH状态该特性的配置。

本发明实施例提供一种小区前向接入信道状态用户设备的高阶调制配置方法和装 置, 在本实施例中, 高阶调制可以是 64QAM的调制方式, 也可以是高于 64QAM的调 制方式, 本实施例并不以此作为限制。 在本实施例及以下的实施例中, 是以高阶调制为 64QAM为例。
图 1为本发明实施例提供的一种 Cell_FACH状态 UE的 64QAM配置方法的流程图, 该方法应用于 RNC, 用于对 Cell_FACH状态 UE进行 64QAM配置, 请参照图 1, 该方 法包括:
步骤 101 : 获取 NodeB上报的小区能力;
其中, NodeB可以通过审计消息或者资源状态指示消息上报该 NodeB下的小区能 力, 以便本实施例的 RNC可以获取到该小区能力。
其中, 该小区能力可以是原有的 NodeB下的小区是否支持 64QAM的能力上报, 也可以采用新增能力, 例如: 64QAM for Cell_FACH的上报, 本实施例并不以此作为限 制。
步骤 102: 根据所述小区能力以及当前 RNC的配置策略确定是否为 Cell_FACH状 态的 UE配置 64QAM;
其中,如果小区能力为小区支持为 Cell_FACH状态 UE使用 64QAM,且当前 RNC 的配置策略允许, 则 RNC可以确定为 Cell_FACH状态的 UE配置 64QAM。
其中, RNC的配置策略是指确定是否为 Cell_FACH状态的 UE配置 64QAM的策 略,在本实施例中,该 RNC的配置策略可以是:仅根据小区能力确定是否为 Cell_FACH 状态的 UE 配置 64QAM , 也可以是根据小区能力以及资源占用情况确定是否为 Cell_FACH状态的 UE配置 64QAM, 还可以是根据小区能力和该特性 (为 Cell_FACH 状态的 UE配置 64QAM 的特性) 的授权来确定是否为 Cell_FACH状态的 UE配置
64QAM。 以上只是举例说明, 本实施例并不以此作为限制。
其中, 资源占用情况包括当前 NodeB是否配置了 E-FACH (增强的前向接入信道) 资源和 E-RACH (增强的随即接入信道) 资源, 或者当前 NodeB是否配置了 E-FACH 资源、 E-RACH资源、以及 HS-DPCCH(HS_DSCH(High Speed Downlink Shared Channel, 高速下行共享信道)的专用物理控制信道)反馈或 CQI (信道质量指示, Channel Quality
Indicator) 反馈, 且当前资源是否空闲。
步骤 103: 如果确定为 Cell_FACH状态的 UE配置 64QAM, 则分别向所述 NodeB 和所述 UE发送 64QAM激活指示。
其中,可以通过系统广播消息或者状态迁移信令向所述 UE发送所述 64QAM激活 指示。 其中, 状态迁移信令可以包括: 无线资源控制 RRC (Radio Resource Control) 连 接建立消息、 无线承载建立消息、 无线承载重配置消息、 无线承载释放消息、 传输信道 重配置消息、 物理信道重配置消息、 或者小区更新确认消息。
其中,可以通过高速下行共享信道数据帧类型 2 (FT2)向所述 NodeB发送 64QAM 激活指示。 其中, 该 FT2中的 64QAM激活指示可以是原有的 UE能力的指示, 也可以 是新增的 UE支持 64QAM的能力指示, 本实施例并不以此作为限制。
在一个实施例中, 如果确定不再为 Cell_FACH状态的 UE配置 64QAM, 则 RNC 可以向 NodeB发送包含连接帧号 CFN (connection Frame Number)指示、不包含 64QAM 激活指示或包含 64QAM去激活指示的 FT2, 也可以向 NodeB发送包含 Cell_FACH状 态 UE的 64QAM去激活指示或不包含 Cell_FACH状态 UE的 64QAM激活指示的小区 重配置请求消息、 物理共享信道重配置请求消息、 或者公共传输信道重配置请求消息; 同时, 为了保证 UE和 NodeB去激活的一致, RNC还要向 UE发送不包含 64QAM激活 指示或者包含 64QAM去激活指示的重配置信令, 或者向 UE发送不包含 64QAM激活 指示的系统广播消息, 以取消 Cell_FACH状态 UE的 64QAM的配置。
通过本实施例的方法, RNC 可以以 UE 为单位或者小区为单位, 为小区中支持
Cell_FACH状态的 UE配置 64QAM, 如此提高了 Cell_FACH状态 UE的峰值速率, 为 后续更多的业务承载在 Cell_FACH状态提供了保障。
图 2为本发明实施例提供的一种 Cell_FACH状态 UE的 64QAM配置方法的流程图, 该方法应用于 RNC, 与图 1所示实施例的方法不同的是, RNC在分别向 NodeB和 UE 发送 64QAM激活指示之前, 先向 NodeB发送 64QAM配置指示, 当 NodeB根据自己 的配置策略确定可以为 Cell_FACH状态 UE配置 64QAM后, RNC再分别向 NodeB和 UE发送 64QAM激活指示。 请参照图 2, 该方法包括:
步骤 201 : 获取 NodeB上报的小区能力;
其中, 小区能力的获取方法与步骤 101相同, 在此不再赘述。
其中, UE能力的获取方法可以通过 UE在上行传输信令中上报支持 64QAM的能 力, 以便本实施例的 RNC可以获取到 UE能力。 其中, 该上行传输信令可以是: UE能 力消息、 系统间切换消息、 RRC 连接建立消息、 小区更新消息、 或者 URA (UTRAN Registration Area, UTRAN (UMTS Terrestrial Radio Access Network, UMTS (Universal Mobile Telecommunications System, 通用移动通信系统) 陆地无线接入网) 登记区域) 更新消息。
步骤 202: 根据所述小区能力以及当前 RNC的配置策略确定是否为 Cell_FACH状 态的 UE配置 64QAM;
其中, 如果 UE能力为支持 64QAM, 小区能力为支持为 Cell_FACH状态 UE使用 64QAM, 且当前 RNC的配置策略允许, 贝 lj RNC可以确定为 Cell_FACH状态的 UE配 置 64QAM。 其中, RNC的配置策略也与步骤 102相同, 在此不做赘述。
步骤 203: 如果确定为 Cell_FACH状态的 UE配置 64QAM, 则向所述 NodeB发送 64QAM配置指示;
其中, 可以通过小区建立请求消息、 小区重配置请求消息、 物理共享信道重配置 消息、 或者公共传输信道建立消息向所述 NodeB发送所述 64QAM配置指示。
步骤 204: 接收所述 NodeB返回的 64QAM配置响应;
其中, 如果 NodeB根据自己的配置策略确定可以为 Cell_FACH状态的 UE配置 64QAM, 则在向 RNC返回的响应消息中通知 RNC。
其中, 对应步骤 203 的消息, 这里的响应消息可以是小区建立响应消息、 小区重 配置响应消息、 物理共享信道重配置响应消息、 或者公共传输信道建立响应消息。
步骤 205: 如果所述 64QAM配置响应为 NodeB可以为 Cell_FACH状态 UE配置 64QAM, 则 RNC分别向所述 NodeB和所述 UE发送 64QAM激活指示。
其中,向 NodeB发送 64QAM激活指示以及向 UE发送 64QAM激活指示的方法与 图 1所示实施例相同, 在此不再赘述。
通过本实施例的方法, RNC可以以 UE为单位或小区为单位, 为 Cell_FACH状态
UE配置 64QAM,如此提高了 Cell_FACH状态 UE的峰值速率, 为后续更多的业务承载 在 Cell_FACH状态提供了保障。
图 3为本发明实施例提供的一种 Cell_FACH状态 UE的 64QAM激活方法的流程图, 该方法应用于 NodeB, 与图 1或图 2所示实施例的方法对应, 请参照图 3, 该方法包括: 步骤 301 : 接收 RNC发送的 64QAM激活指示;
其中, 如步骤 101或者步骤 201所述, NodeB可以先通过审计消息或者资源状态 指示消息向 RNC上报支持为 Cell_FACH状态 UE使用 64QAM能力的信息。 RNC获取 到该 NodeB上报的小区能力后, 根据图 1所示实施例的方法或者图 2所示实施例的方 法处理后, 向本实施例的 NodeB发送该 64QAM激活指示。
其中, 如步骤 103所述, RNC可以通过 FT2将该 64QAM激活指示发送到本实施例 的 NodeB。
其中, 如果该 64QAM激活指示是 FT2中原有的 UE能力上报的指示, 则本实施例 的方法中, NodeB还可以判断小区是否满足配置了 E-FACH和 E-RACH, 或者配置了 E-FACH、 E-RACH 以及 HS-DPCCH反馈或 CQI反馈的条件, 如果满足上述条件, 则 根据当前的资源占用情况决定是否为 Cell_FACH状态 UE配置 64QAM。 其中, 如果该 64QAM激活指示是新增的 UE支持 64QAM的能力指示, 则本实施 例的方法可以直接执行下面的步骤。
步骤 302: 确定 Cell_FACH状态 UE是否支持 64QAM;
其中, 确定 Cell_FACH状态 UE是否支持 64QAM, 可以根据 FT2中的 64QAM激 活指示来确定, 由于在本实施例中, 该 64QAM激活指示是通过 FT2中携带的 UE支持 64QAM的信息来确定, 因此, 根据该 FT2帧, 可以确定 UE是否支持 64QAM。
步骤 303: 如果确定 Cell_FACH状态 UE支持 64QAM, 则根据预先配置的激活方 法激活 64QAM,以便在下行数据传输中按照 64QAM激活对应的 HS-SCCH(High Speed Physical Downlink Shared Control Channel, 高速物理下行共享控制信道) 模式传输调制 方式指示。
其中, 根据预先配置的激活方法激活 64QAM, 可以是直接激活 64QAM, 也即接 收到该 64QAM激活指示后就激活 64QMA; 或者, 在接收到 UE发送的 HS-DPCCH反 馈或者 CQI反馈后激活 64QAM, 也即接收到该 64QAM激活指示后, 还要进一步在接 收到到 UE发送的 HS-DPCCH反馈或者 CQI反馈后激活 64QAM; 或者, 在向 UE发送 用于冲突检测的包含该 UE的 E-RNTI (E-DCH (Enhanced Dedicated Transport Channel, 增强的专用传输信道) Radio Network Temporary Identity, E-DCH无线网络临时标识) 的 E-AGCH (E-DCH Absolute Grant Channel, E-DCH的绝对授权信道)后激活 64QAM, 也即接收到该 64QAM激活指示后,还要进一步在向 UE发送用于冲突检测的包含该 UE 的 E-RNTI的 E-AGCH后激活 64QAM。
在本实施例中, 对应图 2所示实施例的方法, 如果 RNC在向 NodeB发送 64QAM 激活指示之前, 先向 NodeB发送了 64QAM配置指示, 则本实施例在步骤 301之前, 还 可以包括以下步骤:
步骤 3001: 接收 RNC发送的 64QAM配置指示;
其中, 该 64QAM配置指示的接收对应步骤 203中 64QAM配置指示的发送, 在此 不再赘述。
步骤 3002:根据当前 NodeB的配置策略确定是否可以为 Cell_FACH状态的 UE配 置 64QAM。
其中, 当前 NodeB的配置策略可以是当前 NodeB 的算法; 也可以是当前 NodeB 的资源使用情况; 还可以是当前 NodeB 是否具有该特性的授权。 以上只是举例说明, 本实施例并不以此作为限制。 其中,如果确定为支持 Cell_FACH状态的 UE使用 64QAM,也即可以为 Cell_FACH 状态的 UE配置 64QAM, 贝 lj NodeB可以通过发送到 RNC的响应消息向 RNC通知这一 情况。 例如, 通过小区建立响应消息、 小区重配置响应消息、 物理共享信道重配置响应 消息、或者公共传输信道建立响应消息通知 RNC当前 NodeB确定为支持 Cell_FACH状 态的 UE使用 64QAM。
在本实施例中,如果接收到 RNC发送的包含 CFN (连接帧号)指示、不包含 64QAM 激活指示或包含 64QAM去激活指示的 FT2;或者,接收到 RNC发送的包含 Cell_FACH 状态 UE的 64QAM去激活指示或不包含 Cell_FACH状态 UE的 64QAM激活指示的小 区重配置请求消息、物理共享信道重配置请求消息、或者公共传输信道重配置请求消息, 则说明 RNC要取消 Cell_FACH状态 UE的 64QAM的配置, 则本实施例的方法还包括: 去激活 Cell_FACH状态 UE的 64QAM。
在本实施例中,如果 NodeB是直接根据接收到的 RNC发送的 64QAM激活指示激 活 64QAM, 则该 NodeB不能直接去激活 64QAM。 如果 NodeB是在收到 UE的上行 HS-DPCCH反馈或者 CQI反馈后激活 64QAM, 而 HS-DPCCH反馈和 E_RACH资源不 绑定,则 NodeB也不能直接去激活 64QAM。如果 NodeB是在收到 UE的上行 HS-DPCCH 反馈或者 CQI反馈后激活 64QAM,而 HS-DPCCH反馈和 E_RACH资源绑定,则 NodeB 可以在向 UE发送 E-AGCH显示资源释放指示后去激活 64QAM, 也可以在收到 UE发 送的 SI (调度信息, Scheduling Information)为零的隐式资源释放指示后去激活 64QAM。 如果 HS-DPCCH反馈不存在, 也即 E-RACH资源释放, 贝 lj NodeB可以在向 UE发送 E-AGCH显示资源释放指示后去激活 64QAM, 也可以在收到 UE发送的 SI (调度信息) 为零的隐式资源释放指示后去激活 64QAM。
通过本实施例的方法, NodeB可以根据 RNC的指示激活或去激活 Cell_FACH状态 UE的 64QAM,如此提高了 Cell_FACH状态 UE的峰值速率, 为后续更多的业务承载在 Cell.FACH状态提供了保障。
图 4为本发明实施例提供的一种 Cell_FACH状态 UE的 64QAM激活方法的流程图, 该方法应用于 UE, 与图 1或图 2所示实施例的方法对应, 用于根据 RNC的指示激活 64QAM, 请参照图 4, 该方法包括:
步骤 401: 接收 RNC发送的 64QAM激活指示;
其中, 该 UE可以先通过上行传输信令向 RNC上报支持 64QAM能力的信息, 该 上行传输信令包括: UE能力消息、 系统间切换消息、 RRC连接建立消息、 小区更新消 息、 或者 URA更新消息。 RNC获取到该 UE的能力, 在与 NodeB交互的 FT2中, 将该 UE能力提供给 NodeB, 以便 NodeB确定该 UE是否支持 64QAM。
其中, RNC根据图 1或图 2所示实施例的方法处理后, 向本实施例的 UE发送该 64QAM激活指示。
其中, 如步骤 103所述, 该 64QAM激活指示可以通过系统广播消息传递, 也可以 通过状态迁移信令传递, 这里的状态迁移信令包括: RRC连接建立消息、无线承载建立 消息、 无线承载重配置消息、 无线承载释放消息、 传输信道重配置消息、 物理信道重配 置消息、 或者小区更新确认消息。
步骤 402: 根据预先设置的激活方法激活 64QAM, 以便在接收到 NodeB发送的 HS-SCCH信道后, 根据所述 HS-SCCH信道对应的数据包的调制类型进行相应解调。
其中, 根据预先设置的激活方法激活 64QAM, 可以是直接激活 64QAM, 也即驻 留在该小区且处于 Cell_FACH状态的 UE在接收到该 64QAM激活指示后则激活;或者, 向 NodeB发送 HS-DPCCH反馈或者 CQI反馈后激活 64QAM, 也即驻留在该小区且处 于 Cell_FACH状态的 UE在接收到该 64QAM激活指示后,先向 NodeB发送 HS-DPCCH 反馈或者 CQI反馈, 然后激活; 或者, 接收到 NodeB发送的用于冲突检测的包含 UE 的 E-RNTI的 E-AGCH后激活 64QAM, 也即, 驻留在该小区且处于 Cell_FACH状态的 UE在接收到该 64QAM激活指示后, 还要进一步在接收到 NodeB发送的用于冲突检测 的包含 UE的 E-RNTI的 E-AGCH后再激活。
在本实施例中, 如果接收到 RNC发送的不包含 64QAM激活指示或包含 64QAM 去激活指示的重配置信令,或者,接收到 RNC发送的不包含 Cell_FACH状态支持 64QAM 的指示的系统广播消息, 则说明 RNC要取消 Cell_FACH状态 UE的 64QAM的配置, 则本实施例的方法还包括: 去激活 64QAM。
在本实施例中, 如果 Cell_FACH 状态的 UE 是直接根据接收到的 RNC 发送的 64QAM激活指示激活 64QAM, 则该 Cell_FACH状态的 UE不能直接去激活 64QAM。 如果 Cell_FACH 状态的 UE 是在发送了上行 HS-DPCCH 反馈或者 CQI 反馈后激活 64QAM, 而 HS-DPCCH反馈和 E_RACH资源不绑定, 则只要 HS-DPCCH反馈存在, CelLFACH状态的 UE就可以使用 64QAM, 不能直接去激活 64QAM。 如果 Cell_FACH 状态的 UE是在发送了上行 HS-DPCCH反馈或者 CQI反馈后激活 64QAM,而 HS-DPCCH 反馈和 E_RACH资源绑定, 则 UE可以在收到 NodeB发送的 E-AGCH显示资源释放指 示后去激活 64QAM, 也可以在向 NodeB发送 SI (调度信息)为零的隐式资源释放指示 且收到确认后去激活 64QAM。 如果 HS-DPCCH反馈不存在, 也即 E-RACH资源释放, 则 UE可以在在收到 NodeB发送的 E-AGCH显示资源释放指示后去激活 64QAM,也可 以在向 NodeB 发送 SI (调度信息) 为零的隐式资源释放指示且收到确认后去激活 64QAM。
通过本实施例的方法, Cell_FACH状态 UE可以根据 RNC 的指示激活或去激活
64QAM , 如此提高了 Cell_FACH 状态 UE 的峰值速率, 为后续更多的业务承载在 Cell.FACH状态提供了保障。
为了使图 1-图 4所示实施例的方法更加清楚易懂, 以下分别以小区级别和 UE级别 的 Cell_FACH状态 UE的 64QAM配置、 激活和使用为例, 对本实施例的方法进行详细 说明。
图 5为小区级别的 Cell_FACH状态 UE的 64QAM配置、 激活和使用的流程图, 在 本实施例中, 是由网络侧采用公共信令进行 Cell_FACH状态 UE的 64QAM配置, 请参 照图 5, 该流程包括:
步骤 501 : NodeB向 RNC上报小区能力。
其中, 该小区能力可以为原有的 NodeB是否支持 64QAM的能力上报, 也可以是新 增的 Cell_FACH状态的 64QAM支持能力上报, 例如 64QAM for Cell_FACH的上报。
其中,该 NodeB可以通过审计(audit)消息或者资源状态指示(RESOURCE STATUS INDICATION ) 消息向 RNC 上报其小区能力, 也即, 上述消息中包含小区支持为 Cell_FACH状态 UE配置 64QAM的能力。
其中, UE 也可以向 RNC 上报 UE 能力, 但由于本实施例是针对小区级别的
Cell_FACH状态 UE的 64QAM的配置和激活, 因此, 在配置过程中可以不考虑 UE能 力, 而在具体的数据传输中由 NodeB去决策。
步骤 502: RNC根据该小区能力以及当前 RNC的配置策略确定是否为 Cell_FACH 状态 UE配置 64QAM;
其中, 确定是否为 Cell_FACH状态 UE配置 64QAM的方法已经在步骤 102作了说 明, 在此不再赘述。
步骤 503: 如果确定为 Cell_FACH状态 UE配置 64QAM, 贝 lj RNC向 NodeB发送 64QAM配置指示, 指示 NodeB配置 64QAM的能力。
其中, 该 64QAM配置指示可以通过小区建立请求 (CELL SETUP REQUEST) 消 息、 小区重配置请求 (CELL RECONFIGURATION REQUEST) 消息、 物理共享信道重 配置请求 (PHYSICAL SHARED CHANNEL RECONFIGURATION REQUEST) 消息、 公共传输信道建立请求 (COMMON TRANSPORT CHANNEL SETUP REQUEST) 消息 等来传递。
步骤 504: NodeB根据所述 64QAM配置指示以及当前的配置策略确定是否可以为 Cell_FACH状态的 UE使用 64QAM。
其中, 配置策略可以是根据 NodeB的算法确定是否可以为 Cell_FACH状态 UE使 用 64QAM, 也可以是根据 NodeB的算法以及资源占用情况确定是否可以为 Cell_FACH 状态 UE使用 64QAM, 还可以是根据 NodeB的算法、 资源占用情况以及是否授权来确 定是否为 Cell_FACH状态 UE使用 64QAM。 本实施例并不以此作为限制。
步骤 505: NodeB向 RNC返回响应消息;
其中, 当确定可以为 Cell_FACH状态 UE使用 64QAM时, NodeB还在小区建立响 应 (CELL SETUP RESPONSE) 消息、 小区重配置响应 (CELL RECONFIGURATION RESPONSE ) 消息、 物理共享信道重配置响应 (PHYSICAL SHARED CHANNEL RECONFIGURATION RESPONSE ) 消息、 或者公共传输信道建立响应 (COMMON TRANSPORT CHANNEL SETUP RESPONSE) 消息中将这一结果通知 RNC。
步骤 506: RNC向 NodeB发送 64QAM激活指示;
其中, 该 64QAM激活指示可以通过 FT2发送, 例如通过 FT2中原有的 UE能力信 息指示, 或者通过在 FT2中新增 64QAM能力信息指示, 本实施例并不以此作为限制。
步骤 507: NodeB根据所述 64QAM激活指示激活 64QAM。
其中, NodeB根据从 FT2 (HS-DSCH DATA FRAME Type 2) 中获取的 UE能力信 息, 确定 UE是否支持 64QAM, 当 UE支持 64 QAM时, 则可以通过以下方法激活 64QAM, 包括:
1、 直接激活, 即, 只要 Node B收到 RNC的 64QAM激活指示则激活 64QAM;
2、 在收到该 UE的上行 HS-DPCCH反馈或 CQI反馈之后激活 64QAM;
3、 在 E_RACH资源冲突检测之后激活 64QAM, BP : Node B向该 UE发送用于冲 突检测的包含 UE的 E-RNTI (E-DCH Radio Network Temporary Identity, E-DCH无线网 络临时标识) 的 E-AGCH (E-DCH绝对授权信道) 之后激活 64QAM。
步骤 508: RNC向 UE发送 64QAM激活指示;
其中, 可以通过系统广播消息(例如 SIB5)携带当前小区支持 Cell_FACH状态 UE 的 64QAM的指示来向 UE发送该 64QAM激活指示。 其中, 由于 UE与 NodeB要同步激活 64QAM, 因此, RNC可以通过系统广播消息 将小区支持 Cell_FACH状态 UE的 64QAM的信息告知 UE,以便 UE据此激活 64QAM。
以上是以系统广播消息为例, 但本实施例并不以此作为限制, 例如通过图 6所示的 状态迁移信令的方式也可以, 在此不再赘述。
步骤 509: 当前小区的 UE根据系统广播消息的指示确定激活 64QAM。
其中, 对应 Node B激活 64QAM的三种方式, UE有以下三种 64QAM激活方式:
1、 直接激活;
只要 UE支持 Cell_FACH状态的 64QAM,且收到 RNC的 SIB中包含当前小区支持 Cell_FACH状态 UE的 64QAM的指示则激活 64QAM。
2、Cell_FACH状态的 UE在发送上行 HS-DPCCH反馈或 CQI反馈之后激活 64QAM;
3、 Cell_FACH状态的 UE在接收到 Node B发送的用于冲突检测的包含 UE的 E-RNTI 的 E-AGCH之后激活 64QAM。
其中, UE侧 64QAM和 Node B侧 64QAM的激活必须保持同步, 防止 UE错误的 检测数据包, 因此上述 UE和 Node B侧的三种激活方式一一对应, BP : UE采用方式一, Node B也需要采用方式一, 依次类推。
步骤 510: NodeB激活 64QAM后, 在进行下行数据传输时, 按照 64QAM激活对 应的 HS-SCCH模式传输调制方式指示;
步骤 511 : 当 Cell_FACH状态 UE的 64QAM激活之后, 下行数据接收时, UE在解 析 HS-SCCH信道后, 当调制模式指示位为 1时, 进一步确定该 HS-SCCH对应的数据 包为 16QAM还是 64QAM的模式。
在本实施例中, 还可能包含 64QAM的去激活过程。 当 RNC确定去激活该小区的 64QAM时, 该流程还包括:
步骤 512: RNC确定是否去激活该小区的 64QAM;
其中, RNC确定是否去激活该小区的 64QAM可能根据 RNC自身的情况确定, 也 可能是由 Node B触发。其中 Node B触发的方式包含 Node B下小区能力的改变或者 Node B下小区的资源使用情况发生变化。 Node B在审计过程或者资源状态指示中指示 RNC 该种变化。
步骤 513: RNC指示 NodeB去激活 64QAM;
其中, RNC可以通过在以下消息中包含 Cell_FACH状态 UE的 64QAM去激活指示, 或者在以下消息中不再包含 Cell_FACH状态 UE的 64QAM激活指示,来去激活 64QAM。 这些消息包括但不限于: 小区重配置请求 (CELL RECONFIGURATION REQUEST) 消 息 , 或者物理共享信道重配置请求 ( PHYSICAL SHARED CHANNEL RECONFIGURATION REQUEST) 消息, 或者公共传输信道重配置请求 (COMMON TRANSPORT CHANNEL RECONFIGURATION REQUEST)消息。 如此, 可以完成小区 级别的 Cell_FACH状态 UE的 64QAM去激活, 也即, RNC以小区为单位, 指示 NodeB 去激活该小区范围内的 Cell_FACH状态 UE的 64QAM。
步骤 514: NodeB去激活 Cell_FACH状态 UE的 64QAM。
在一个实施例中, NodeB可以根据步骤 513中 RNC的指示去激活 64QAM。
在另外一个实施例中, NodeB也可以根据自己的策略去激活 64QMA, 例如: 对应 于激活方式 1, Node B 不存在对单个 UE 的去激活方式; 对应于激活方式 2, 如果 HS-DPCCH反馈和 E_RACH资源不绑定, 则 Node B不存在对单个 UE的去激活方式, 如果 HS-DPCCH反馈和 E_RACH资源绑定, 则去激活方式和对应于激活方式 3的去激 活方式相同; 对应于激活方式 3, 当 HS-DPCCH反馈不存在时则去激活 64QAM, 艮卩: E_RACH资源释放之后则去激活 64QAM。其中, 针对 E_RACH资源的显式资源释放方 式, Node B在发送 E-AGCH进行资源释放之后则去激活 64QAM; 针对 E_RACH资源 的隐式资源释放方式, Node B在收到 UE发送的 SI=0之后则去激活 64QAM。
步骤 515: RNC指示 UE去激活 64QAM;
对于小区级别的去激活, RNC可以通过改变系统广播消息, 例如在 SIB 中不再包 含 Cell_FACH状态支持 64QAM的指示, 来指示 UE去激活 64QAM。
步骤 516: UE去激活 64QAM。
在一个实施例中, UE根据步骤 515中 RNC的指示去激活 64QAM。
在另外一个实施例中, UE根据自己的策略去激活 64QAM, 例如: 对应于激活方式 1, UE不存在去激活方式; 对应于激活方式 2, 如果 HS-DPCCH反馈和 E_RACH资源 不绑定, 则只要 HS-DPCCH反馈存在, UE就可以使用 64QAM, 不存在对单个 UE的 去激活方式; 如果 HS-DPCCH反馈和 E_RACH资源绑定, 去激活方式和对应于激活方 式 3 的去激活方式相同; 对应于激活方式 3, 当 HS-DPCCH 反馈不存在时则去激活 64QAM, BP : E_RACH资源释放之后则去激活 64QAM。其中,针对显式资源释放方式, UE在收到 Node B发送的 E-AGCH资源释放指示之后则去激活 64QAM;针对隐式资源 释放方式, UE在发送 SI=0且收到 ACK之后则去激活 64QAM。
步骤 517: NodeB去激活 64QAM后, 在进行下行数据传输时, 不再按照 64QAM 激活对应的 HS-SCCH模式传输调制方式指示;
步骤 518: UE去激活 64QAM后, 下行数据接收时, 不再进行 64QAM的判断。 本实施例的方法通过在 Cell_FACH状态引入 64QAM的配置方式提高了 Cell_FACH 状态 UE的峰值速率, 为后续更多的业务承载在 Cell_FACH状态提供了保障。
图 6为 UE级别的 Cell_FACH状态 UE的 64QAM配置、 激活和使用的流程图, 在 本实施例中, 是由网络侧采用专用信令进行 Cell_FACH状态 UE的 64QAM配置, 其中 与图 5相同的内容不再赘述。 请参照图 6, 该流程包括:
步骤 601 : NodeB向 RNC上报小区能力。
其中, 该上报方式与步骤 501相同, 在此不再赘述。
步骤 602: UE向 RNC上报 UE能力。
其中, UE可以在上行传输信令中上报支持 64QAM的能力, 该上行传输信令可以 为: UE能力消息 (UE CAPABILITY INFORMATION )、 或者系统间切换消息 (INTER RAT HANDOVER INFO)、 或者 RRC连接建立 (RRC connection setup) 消息、 或者小 区更新(cell update)消息、 或者 URA更新(URA update)消息, 但并不以此作为限制。
步骤 603: RNC根据小区能力以及当前 RNC的配置策略确定是否为 Cell_FACH状 态的 UE配置 64QAM;
其中, 该确定方式与步骤 502相同, 在此不再赘述。
步骤 604: RNC通过 HS-DSCH DATA FRAME TYPE2向 NodeB发送 64QAM激活 指示。
其中, 与图 5所示实施例相同在本实施例中, RNC在向 NodeB发送 64QAM激活 指示之前, 也可以先向 NodeB 发送 64QAM 配置指示, 以询问 NodeB 是否可以为 Cell_FACH状态 UE配置 64QAM。 具体请参考步骤 503— 505。
步骤 605: Node B激活 64QAM;
其中, 该 Node B激活 64QAM有以下三种方式:
1、 Node B为所有 Cell_FACH状态下支持 64QAM的 UE激活 64QAM, 即: Node B 收到 HS-DSCH DATA FRAME TYPE 2中包含 UE支持 64QAM的信息, 则激活;
2、 Node B根据 FT2中 64QAM的激活指示, 在收到该 UE的 HS-DPCCH反馈或 CQI反馈之后激活 64QAM;
3、 Node B根据 FT2中的 64QAM激活指示,在向 UE发送用于冲突检测的 E-AGCH 之后激活 64QAM。 步骤 606: RNC在发送给 UE的状态迁移信令中包含 64QAM激活指示, 例如 UE 64QAM的配置信息;
其中, 该状态迁移信令可以是当前可以将 UE迁移到 Cell_FACH状态的所有信令, 例如: RRC连接建立(RRC CONNECTION SETUP)消息、或者无线承载建立(RADIO BEARER SETUP )、 或者无线承载重配置 ( RADIO BEARER RECONFIGURATION ) 消 息、 或者无线承载释放 (RADIO BEARER RELEASE) 消息、 或者传输信道重配置 ( TRANSPORT CHANNEL RECONFIGURATION ) 消息、 或者物理信道重配置 ( PHYSICAL CHANNEL RECONFIGURATION ) 消息、 或者小区更新确认 (CELL UPDATE CONFIRM ) 消息等。
以上是以状态迁移信令为例, 但本实施例并不以此作为限制, 例如通过图 5所示的 系统广播消息的方式也可以, 在此不再赘述。
步骤 607: UE激活 64QAM。
其中, UE收到该指示信息后, 也有如下三种激活方式:
1、 收到 RNC的指示则激活 64QAM;
2、Cell_FACH状态的 UE在发送上行 HS-DPCCH反馈或 CQI反馈之后激活 64QAM;
3、Cell_FACH状态的 UE在接收到 Node B发送的用于冲突检测的 E-AGCH之后激 活 64QAM。
步骤 608: Node B激活 64QAM之后, 在下行数据传输中按照 64Q AM激活对应的 HS-SCCH模式传输调制方式指示;
步骤 609: UE在接收 HS-SCCH信道后, 当调制模式指示位为 1时, 进一步确定该
HS-SCCH对应的数据包为 16QAM还是 64QAM的模式。
在本实施例中, 当 RNC由于某种原因需要去激活某个 UE的该特性时, 可以如图 5 所示实施例, 以小区为单位去激活小区范围内的 UE的 64QAM,也可以以 UE为单位去 激活特定 UE的 64QAM。 其中:
对于小区级别的去激活, RNC可以通过改变系统广播消息, 例如在 SIB 中不再包 含 Cell_FACH状态支持 64QAM的指示, 来指示 UE去激活 64QAM。 RNC可以通过在 以下消息中包含 Cell_FACH状态 UE的 64QAM去激活指示, 或者在以下消息中不再包 含 Cell_FACH状态 UE的 64QAM激活指示, 来去激活 NodeB侧的 64QAM。 这些消息 包括但不限于: 小区重配置请求 (CELL RECONFIGURATION REQUEST) 消息, 或者 物理共享信道重配置请求 ( PHYSICAL SHARED CHANNEL RECONFIGURATION REQUEST)消息, 或者公共传输信道重配置请求(COMMON TRANSPORT CHANNEL RECONFIGURATION REQUEST) 消息。 如此, 可以完成小区级别的 Cell_FACH状态 UE的 64QAM去激活, 也即, RNC以小区为单位, 指示 NodeB去激活该小区范围内的 Cell_FACH状态 UE的 64QAM。
对于 UE级别的去激活, RNC可以通过重配置信令指示 UE去激活 64QAM, 例如 通过在重配置信令中不包含 64QAM激活指示, 或者在重配置命令中包含 64QAM去激 活指示, 来指示 UE去激活 64QAM。 RNC可以通过向 NodeB发送包含连接帧号 CFN 指示、 不包含 64QAM激活指示或包含 64QAM去激活指示的 FT2, 来去激活 NodeB侧 的 64QAM。 例如, 对于 NodeB的 context中不保存 64QAM激活信息的情况, RNC只 需要在 FT2中不包含 64QAM指示即可; 对于 NodeB的 context中保存 64QAM激活信 息的情况, RNC需要在 FT2中包含 64QAM去激活指示, 而为了保持 UE侧和 NodeB 侧去激活的一致性, RNC还要在该 FT2中携带 CFN指示, 以告诉 NodeB在某个 CFN 去激活 64QAM。 如此, 可以完成 UE级别的 64QAM去激活, 也即, RNC以 UE为单 位, 指示 NodeB去激活指定 Cell_FACH状态 UE的 64QAM。
本实施例的方法通过在 Cell_FACH状态引入 64QAM的配置方式提高了 Cell_FACH 状态 UE的峰值速率, 为后续更多的业务承载在 Cell_FACH状态提供了保障。
