Description

一种确定资源位置的方法、 设备和系统 本申请要求于 2009年 8 月 11 日提交中国专利局， 申请号为 200910090792.5 , 发明名称为 "一种确定资源位置的方法、 设备和系 统"的中国专利申请的优先权，其全部内容通过引用结合在本申请中。 技术领域
本发明涉及通信技术领域， 尤其涉及一种确定资源位置的方法、 设备和系统。 背景技术
TD-SCDMA ( Time Division-Synchronous Code Division Multiple Access , 时分同步的码分多址技术 ) 系统在 3 GPP ( 3rd Generation Partnership Proj ect, 第三代伙伴项目） 的 Release5中引入了 HSDP A ( High Speed Downlink Packet Access, 高速下行分组接入 )技术， 从 而提高了 UE ( User Equipment, 用户设备） 的下行速率。
如图 1所示， 为一种 TD-SCDMA移动通信系统中帧结构； 其中， HSDPA中的 TTI ( transmission time interval , 传输时间间隔） 为一个 子帧 （5ms ) , 在 HSDPA的传输过程中， 网络侧设备为每个 UE配置 了一组 HS-SCCH ( High-Speed Shared Control Channel, 高速共享控制 信道） ， 用于对 UE进行持续监听。
具体的， 在基站对小区内的所有用户进行调度时， 需要确定调度 过 HS-SCCH通知 UE在对应的物理资源上接收数据； 其中， 无论是首 次传输或者是重传， UE均将按照该 HS-SCCH通知的信息接收数据。
其中， 在现有协议中， 为了保证广播的覆盖与质量， 辅载波 TS ( Time Slot, 时隙） 0的时隙、 码道资源都没有被使用， 即 TS0是不能 作为 HS-DSCH ( High-Speed Downlink Shared Channel, 高速下行共享 信道）的资源的。 但是在现有的 TD-SCDMA系统 N频点的小区中， 随 着 F频段的引入， TS0的使用被重新考虑。
在实现本发明的过程中，发明人发现现有技术中至少存在以下缺 点：
当 TD-SCDMA 系统中需要考虑辅载波 TS0 的使用且用作 HS-DSCH资源时， 根据现有系统的典型配置， HS-SCCH—般被配置 在 TS6, 当基站分配的 HS-DSCH在 TS0时， 则会出现如图 2所示的 定时关系， 由于 HS-SCCH和 HS-DSCH为紧接着的两个时隙； 会出 现 UE还没有解析完 HS-DSCH时， 网络侧已经开始在 HS-DSCH上 发送下行数据了， 此时， UE是无法及时完成 HS-SCCH 的解码及 HS-DSCH数据的接收过程的。 发明内容
本发明提供一种确定资源位置的方法、设备和系统， 以准确地确 定基站分配的 HS-DSCH所在子帧的位置。
为了达到上述目的， 本发明实施例提供一种确定资源位置的方 法， 包括：
用户设备 UE根据高速共享控制信道 HS-SCCH获取高速下行共 享信道 HS-DSCH所在时隙；
所述 UE根据所述 HS-DSCH所在时隙确定所述 HS-DSCH所在 子帧。
另一方面， 本发明实施例提供一种用户设备 UE, 包括： 获取模块， 用于根据 HS-SCCH获取 HS-DSCH所在时隙； 确定模块， 用于根据所述获取模块获取的 HS-DSCH所在时隙确 定所述 HS-DSCH所在子帧。
另一方面， 本发明实施例提供一种网络侧设备， 包括： 处理模块， 用于在 HS-SCCH中添加 HS-DSCH的时隙信息， 并 将所述 HS-SCCH发送给 UE, 由所述 UE根据所述 HS-SCCH获取所 述 HS-DSCH 所在时隙以及根据所述 HS-DSCH所在时隙确定所述
HS-DSCH所在子帧； 发送模块， 用于根据所述处理模块添加的 HS-DSCH时隙信息向 UE发送所述 HS-DSCH, 由所述 UE在所述 HS-DSCH所在子帧中的 HS-DSCH所在时隙接收来所述 HS-DSCH。
另一方面， 本发明实施例提供一种确定资源位置的系统， 包括： 网络侧设备， 用于向 UE发送 HS-SCCH;
UE, 用于根据所述 HS-SCCH获取 HS-DSCH所在时隙； 并根据 所述 HS-DSCH所在时隙确定所述 HS-DSCH 所在子帧； 并在所述 HS-DSCH所在子帧中的 HS-DSCH所在时隙接收来自所述网络侧设 备的 HS-DSCH。
与现有技术相比， 本发明实施例至少具有以下优点：
UE可以根据基站分配的 HS-DSCH所在时隙确定其所在子帧； 当为 UE分配了 TS0的 HS-DSCH资源时， 为 UE预留了足够的对 HS-SCCH 的解码时间， 解决了 TD-SCDMA 系统中采用 TS0作为 HS-DSCH 资源时， 会出现 UE无法及时完成 HS-SCCH 的解码和 HS-DSCH数据接收的问题。
而且根据实际需要对 HS-SCCH与 HS-DSCH资源之间固定间隔 进行调整， 避免了网络侧设备为不同类型 UE 分配不同资源时 HS-SICH的冲突问题。 附图说明

下面将结合本发明中的附图，对本发明实施例中的技术方案进行 清楚、 完整地描述， 显然， 所描述的实施例仅仅是本发明的一部分实 施例， 而不是全部的实施例。 基于本发明中的实施例， 本领域普通技 术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属 于本发明实施例保护的范围。
如背景技术，当 TD-SCDMA系统中可以采用 TS0作为 HS-DSCH 资源时， 会出现 UE无法及时完成 HS-SCCH的解码和 HS-DSCH数 据接收的过程； 而且如果规定网络侧分配的 HS-DSCH包含 TS0时， HS-DSCH资源固定出现在 HS-SCCH的下下一个子帧， 而 HS-DSCH 与 HS-SICH的定时关系保持不变。
由于传统的 HSDPAUE (即不支持 HS-DSCH资源配置在 TS0的 UE ) 而言， 定时关系是不能改变的； 此时， 如果要求基站在调度时 区分传统的 HSDPA UE, 和支持 HS-DSCH配置在 TS0的 UE, 调度 过程比较复杂， 并且会发生冲突， 如图 3所示的一种冲突情况。 在子 帧 #n, 基站通过 HS-SCCH为 UE1分配了支持包含 TS0的 HS-DSCH 资源， 所述 HS-DSCH在子帧 #n+2的 TS0和 TS5; 根据 HS-DSCH与 HS-SICH ( High-Speed Shared Information Channel, 高速共享信息信 道） 的定时关系， UE1需要在子帧 #n+4进行 HS-SICH反馈。 而如果 基站在子帧 #n+l对一个传统的 HSDPA UE2也使用相同的 HS-SCCH 进行调度， 分配的资源为子帧 #n+2的时隙 4资源， 此时， UE2需要 在子帧 #n+4使用相同的 HS-SICH进行反馈， 可见， UE1和 UE2的反 馈发生了冲突。
为了解决上述问题， 发明实施例提供了一种确定资源位置方法、 设备和系统， 在该确定资源位置的方法中， 网络侧设备向 UE发送了 HS-SCCH后， UE根据该 HS-SCCH的指示判断 HS-DSCH资源是否 包含时隙 0, 如果不包含时隙 0, 则 HS-DSCH所在子帧为 HS-SCCH 所在子帧 N 的下一个子帧 N+1; 如果包含时隙 0 , 则时隙 0 的 HS-DSCH所在子帧为 HS-SCCH所在子帧 N的下下一个子帧 N+2, 其它时隙的 HS-DSCH资源所在子帧为 HS-SCCH所在子帧 N的下一 个子帧 N+l。
通过使用上述方法， UE可以根据基站分配的 HS-DSCH所在时 隙确定其所在子帧； 当为 UE分配了 TS0的 HS-DSCH资源时， 为 UE预留了足够的对 HS-SCCH的解码时间，解决了 TD-SCDMA系统 中采用 TS0 作为 HS-DSCH 资源时， 会出现 UE 无法及时完成 HS-SCCH的解码和 HS-DSCH数据接收的问题。 而且本发明实施例 中， 可以根据实际需要对 HS-SCCH与 HS-DSCH资源之间固定间隔 进行调整， 避免了网络侧设备为不同类型 UE 分配不同资源时 HS-SICH的冲突问题。
本发明实施例一提供一种确定资源位置的方法， 如图 4所示， 包 括以下步骤： 步骤 401 , 用户设备 UE接收来自网络侧设备的高速共享控制信 道 HS-SCCH。
步骤 402, 所述 UE根据所述 HS-SCCH获取高速下行共享信道 HS-DSCH所在时隙。
其中， 所述 UE 根据所述 HS-SCCH 获取高速下行共享信道 HS-DSCH所在时隙具体包括； 所述 UE对所述 HS-SCCH进行解码， 所述解码后的 HS-SCCH中携带了所述 HS-DSCH的时隙信息。
步骤 403 , 所述 UE 根据所述 HS-DSCH 所在时隙确定所述 HS-DSCH所在子帧。
其中，所述 UE根据所述 HS-DSCH所在时隙确定所述 HS-DSCH 所在子帧具体包括：
所述 UE判断所述 HS-DSCH所在时隙是否包含时隙 0; 当所述 HS-DSCH所在时隙不包含时隙 0时，所述 UE确定所述 HS-DSCH所 在子帧为所述 HS-SCCH所在子帧 N 的下一个子帧 N+1 ; 当所述 HS-DSCH所在时隙只包含时隙 0时，所述 UE确定所述 HS-DSCH所 在子帧为所述 HS-SCCH所在子帧 N的下下一个子帧 N+2; 当所述 HS-DSCH所在时隙包含时隙 0和其他时隙时， 所述 UE确定时隙 0
N+2; 其它时隙的 HS-DSCH所在子帧为所述 HS-SCCH所在子帧 N 的下一个子帧 N+l。
步骤 404,所述 UE在所述 HS-DSCH所在子帧中的 HS-DSCH所 在时隙接收来自所述网络侧设备的 HS-DSCH。
进一步的， 所述 UE在所述 HS-DSCH所在子帧中的 HS-DSCH 所在时隙接收来自所述网络侧设备的 HS-DSCH之后， 还包括： 所述 UE在高速共享信息信道 HS-SICH上向所述网络侧设备返回响应信 息。
具体的， 所述 UE在高速共享信息信道 HS-SICH上向所述网络 侧设备返回响应信息具体包括： 所述 HS-DSCH所在时隙中不包含时 隙 0, 所述 UE在 HS-DSCH所在子帧的下下一个子帧的 HS-SICH上 向所述网络侧设备返回响应信息； 或 , 所述 HS-DSCH所在时隙中包 含时隙 0, 所述 UE在所述时隙 0对应的 HS-DSCH所在子帧的下一 个子帧的 HS-SICH上向所述网络侧设备返回响应信息。
所述 UE在高速共享信息信道 HS-SICH上向所述网络侧设备返 回响应信息还包括： 所述 UE在 HS-SICH上向所述网络侧设备返回 响应信息时， 所述 HS-DSCH 中的最后一个 HS-DSCH 和对应的 HS-SICH之间要有不小于 8的时隙偏移。
可见， 通过使用本发明实施例提供的方法， UE可以根据基站分 配的 HS-DSCH所在时隙确定其所在子帧； 当为 UE分配了 TS0的 HS-DSCH资源时， 为 UE预留了足够的对 HS-SCCH的解码时间，解 决了 TD-SCDMA系统中采用 TS0作为 HS-DSCH资源时，会出现 UE 无法及时完成 HS-SCCH的解码和 HS-DSCH数据接收的问题。 而且 根据实际需要对 HS-SCCH与 HS-DSCH资源之间固定间隔进行调整， 避免了网络侧设备为不同类型 UE分配不同资源时 HS-SICH的冲突 问题。
本发明实施例二提供一种确定资源位置方法，该方法可以应用于 TD-SCDMA系统中可以采用 TS0作为 HS-DSCH资源的应用场景中， 当然，对于不采用 TS0作为 HS-DSCH资源的应用场景以及其他系统 中对应的应用场景， 本发明实施例可以同样适用， 在此不再赘述。 如 图 5所示， 上述的确定资源位置方法包括以下步骤：
步骤 501 , 网络侧设备向 UE发送 HS-SCCH。
其中， 该 HS-SCCH上承载的内容包括但不限于 HS-DSCH所占 用的物理资源、 本次传输所采用的调制方式、 传输块大小、 HARQ ( Hybrid Automatic Repeat reQuest, 混合自动重传请求）信息、 新数 据指示以及 UE ID (标识 )等信息。
该网络侧设备包括但不限于 RNC ( Radio Network Controller, 无 线网络控制器）、 NB ( Node B, 节点 B )、 基站等， 需要说明的是， 该网络侧设备并不局限于上述设备，所有位于网络侧的设备均在本发 明实施例保护范围之内， 为了方便描述， 本发明实施例中的网络侧设 备以基站为例进行说明。
步骤 502 , UE 接收并解码该 HS-SCCH , 根据基站分配的 HS-DSCH所在时隙， 确定基站分配的 HS-DSCH所在子帧。
其中，当基站要给某个 UE在 HS-DSCH上发送下行增强数据时， 基站将首先向 UE发送 HS-SCCH。 而该 UE通过解码该 HS-SCCH, 确定 HS-DSCH 所在的时隙和子帧， 从而在该确定的位置接收 HS-DSCH资源。
具体的， 该 UE根据基站分配的 HS-DSCH所在时隙， 确定基站 分配的 HS-DSCH 所在子帧具体包括： UE判断 HS-SCCH指示的 HS-DSCH资源是否包含时隙 0, 如果不包含时隙 0, 则 HS-DSCH所 在子帧为 HS-SCCH所在子帧 N的下一个子帧 N+1;如果包含时隙 0, 则时隙 0的 HS-DSCH所在子帧为 HS-SCCH所在子帧 N的下下一个 子帧 N+2, 其它时隙的 HS-DSCH资源所在子帧为 HS-SCCH所在子 帧 N的下一个子帧 N+l。
进一步的， 当不包含时隙 0时， 判断出的 HS-DSCH所在子帧为 HS-SCCH所在子帧 N的下一个子帧 N+1 ,是根据现有的 HSDPA中， HS-SCCH与 HS-DSCH之间的定时关系确定的， 该定时关系具体为 对应下一次有效的 HS-DSCH 分配， HS-DSCH相应的时隙信息在 HS-SCCH上携带，所指示的 HS-DSCH将会在携带 HS-DSCH相应信 息的 HS-SCCH的下一个子帧上发送。
如图 6所示， 为一种 HS-SCCH和 HS-DSCH之间的定时关系。 其中，在该定时关系中不考虑 DwPTS (下行导频时隙 )时隙和 UpPTS (上行导频时隙）。
步骤 503 , UE根据该 HS-DSCH资源的时隙和子帧接收 HS-DSCH 数据。
其中，当 UE解码该 HS-SCCH时，可以获得基站分配的 HS-DSCH 所在时隙。 进一步的， 根据上述步骤 502 中的处理过程可以确定 HS-DSCH所在子帧，即 UE可以根据该时隙和子帧接收 HS-DSCH数 据。 步骤 504, UE对接收到的 HS-DSCH数据进行解调和解码，并在 HS-SICH上反馈 ACK ( ACKnowledge Character, 确认字符）， 或者 NACK以及 CQI ( Channel Quality Indicator, 信道质量指示）信息； 即 UE在接收到 HS-DSCH数据时， 需要向基站返回响应信息。 需要 说明的是， 该 HS-SICH的位置是由网络侧设备预先通知 UE的， 本 发明实施例中不再赘述。
具体的， 对于该 HS-SICH所在的子帧， 也是有位置要求的， 当 HS-DSCH数据中不包含时隙 0时，该 HS-SICH所在的子帧为根据现 有的 HSDPA中， HS-DSCH与 HS-SICH的定时关系确定的； 该定时 关系具体为： HS-SCCH需要对应一个 HS-SICH, 并通过该 HS-SICH 携带 ACK/NACK信息和 CQI信息。 进一步的， 该 HS-SCCH 和 HS-SICH之间的对应关系是由网络侧设备预定义的， 对于所有的 UE 都是一样的； 其中， 对于 UE来说， HS-DSCH和对应的 HS-SICH之 间要有 nHS-SICH 大于等于 9 的时隙偏移， 即在接收到最后一个 HS-DSCH后， 需要经过 9个时隙之后才能发送 HS-SICH。 如图 7所 示为一种 HS-DSCH和 HS-SICH之间的定时关系。 同样的，在该定时 关系中不考虑 DwPTS和 UpPTS。 其中， 在 CELL-DCH (小区专用信 道）状态和 CELL_FACH ( forward access Channel, 前向接入信道） 的状态下， 具有专用标识的 UE将在下一个可用的 HS-SICH上发送 HS-DSCH所对应的 ACK/NACK, 本发明实施例中不再赘述。
本发明实施例中， 当 HS-DSCH数据中包含时隙 0 时， UE 的 HS-SICH反馈必须在时隙 0对应的 HS-DSCH所在子帧的下一个子帧 内发送， 从而避免了网络侧设备为不同类型 UE 分配不同资源时 HS-SICH的冲突问题。 例如， 对于图 3所示冲突情况； 在子帧 #n, 基 站通过 HS-SCCH为支持 HS-DSCH配置在 TS0的 UE1分配了子帧 #n+2的 TS0和 TS5的 HS-DSCH资源； 本发明实施例中， UE1将在 子帧 #n+3进行 HS-SICH反馈（现有技术中根据 HS-DSCH与 HS-SICH 的定时关系， UE1需要在子帧 #n+4进行 HS-SICH反馈）。 如果基站 在子帧 #n+l对一个传统的 HSDPA (没有配置 TS0的 UE ) UE2也使 用相同的 HS-SCCH进行调度，分配的资源为子帧 #n+2的时隙 4资源， 此时，根据 HS-DSCH与 HS-SICH的定时关系， UE2需要在子帧 #n+4 使用 HS-SICH进行反馈， 可见， 当 HS-DSCH数据中包含时隙 0时， UE的 HS-SICH反馈通过在时隙 0对应的 HS-DSCH所在子帧的下一 个子帧内发送， 避免了 UE1和 UE2之间的冲突。
可以看出， 由于一个子帧内有 7个时隙， UE的 HS-SICH反馈必 须在时隙 0对应的 HS-DSCH所在子帧的下一个子帧内发送， 即 UE 需要根据 nHS-SICH大于等于 8个时隙确定反馈的 HS-SICH所在子 帧； 其中， 该过程中 DwPTS和 UpPTS也不需要考虑。
以下结合 3 种具体的情况对本发明实施例中的确定资源位置方 法进行详细说明， 该 3种情况分别为 HS-DSCH资源不包含时隙 0; HS-DSCH资源只包含时隙 0; HS-DSCH资源包含时隙 0和其他时隙。 基于上述本发明实施例二中提供的确定资源位置方法，本发明实施例 三提供一种确定资源位置方法， 该方法是在实施例二的应用场景下， HS-DSCH资源中不包含时隙 0的情况； 如图 8所示一种 HS-DSCH 位置、 HS-DSCH位置以及 HS-SICH位置之间的对应关系， 该对应关 系只是一种示意情况， 根据实际需要还可以选择其他队应关系， 该确 定资源位置方法如图 9所示， 包括以下步骤：
步骤 901 ,基站向 UE发送 HS-SCCH,其中，基站通过该 HS-SCCH 向 UE指示为该 UE分配的 HS-DSCH位于时隙 3至时隙 5; 当然， 该时隙情况为根据实际需要任意选择的， 只需要该时隙不包括时隙 0 即可。
步骤 902, UE接收并解码该 HS-SCCH, 获得 HS-DSCH资源中 不包含时隙 0, 确定出 HS-DSCH所在子帧为 HS-SCCH所在子帧 N 的下一个子帧 N+l。
具体的， UE 正确解码 HS-SCCH后， 判断 HS-SCCH指示的 HS-DSCH资源中不包含时隙 0,则认为基站分配的 HS-DSCH所在子 帧为 HS-SCCH所在子帧 N的下一个子帧 N+l。 即 HS-DSCH在子帧 N+1的时隙 3至时隙 5。 步骤 903 , UE在 HS-SCCH所在子帧 N的下一个子帧 N+1接收 HS-DSCH数据，其中， UE接收 HS-DSCH数据的时隙已经预先约定， 在此不再赘述。
步骤 904, UE对 HS-DSCH数据进行解调和解码，并在 HS-SICH 上反馈 ACK/NACK以及 CQI信息， 其中， 该 HS-SICH上的反馈是 根据现有的定时关系在相应子帧进行反馈的。
基于上述本发明实施例二中提供的确定资源位置方法，本发明实 施例四提供一种确定资源位置方法， 该方法是 HS-DSCH资源中只包 含时隙 0的情况； 如图 10所示一种 HS-DSCH位置、 HS-DSCH位置 以及 HS-SICH位置之间的对应关系，该对应关系只是一种示意情况， 该确定资源位置方法如图 11所示， 包括以下步骤：
步骤 1101 , 基站向 UE 发送 HS-SCCH, 其中， 基站通过该 HS-SCCH向 UE指示为该 UE分配的 HS-DSCH位于时隙 0。
步骤 1102, UE接收并解码该 HS-SCCH, 获得 HS-DSCH资源为 时隙 0, 确定出 HS-DSCH所在子帧为 HS-SCCH所在子帧 N的下下 一个子帧 N+2。
步骤 1103 , UE在 HS-SCCH所在子帧 N的下下一个子帧 N+2接 收 HS-DSCH数据。
步骤 1104, UE对 HS-DSCH数据进行解调和解码，并在 HS-DSCH 的下一个子帧 N+3进行 HS-SICH反馈。
需要说明的是， 根据图 10中所示的对应关系， HS-SICH配置在 TS1 (为网络侧设备与 UE事先约定的），可见， HS-DSCH与 HS-SICH 之间只间隔 8个时隙；但为了保证 HS-SCCH与 HS-SICH之间的定时 关系， UE必须在子帧 #n+3进行 HS-SICH反馈。
基于上述本发明实施例二中提供的确定资源位置方法，本发明实 施例五提供一种确定资源位置方法， 该方法是 HS-DSCH资源中包含 时隙 0 和其他时隙的情况； 如图 12 所示一种 HS-DSCH位置、 HS-DSCH位置以及 HS-SICH位置之间的对应关系，该对应关系只是 一种示意情况， 该确定资源位置方法如图 13所示， 包括以下步骤： 步骤 1301 , 基站向 UE发送 HS-SCCH, 其中， 基站通过该 HS-SCCH 向 UE指示为该 UE分配的 HS-DSCH位于时隙 0和时隙 4、 时隙 5。 步骤 1302, UE接收并解码该 HS-SCCH, 获得 HS-DSCH资源为时隙 0和时隙 4、时隙 5,确定出时隙 0的 HS-DSCH所在子帧为 HS-SCCH 所在子帧 N的下下一个子帧 N+2,而时隙 4和时隙 5的 HS-DSCH资 源所在子帧为 HS-SCCH所在子帧 N的下一个子帧 N+l。
步骤 1303 , UE在 HS-SCCH所在子帧 N的下下一个子帧 N+2 接收时隙 0所对应的 HS-DSCH数据； 并在 HS-SCCH所在子帧 N的 下一个子帧 N+1接收时隙 4和时隙 5所对应的 HS-DSCH数据。
步骤 1304, UE对 HS-DSCH数据进行解调和解码， 并在时隙 0所对 应的 HS-DSCH数据的下一个子帧 N+3进行 HS-SICH反馈。
可见， 在上述 3种情况下， 通过使用本发明实施例提供的方法， 通过使用上述的 UE可以根据基站分配的 HS-DSCH所在时隙确定其 所在子帧； 当为 UE分配了 TS0的 HS-DSCH资源时， 为 UE预留了 足够的对 HS-SCCH的解码时间，解决了 TD-SCDMA系统中采用 TS0 作为 HS-DSCH资源时， 会出现 UE无法及时完成 HS-SCCH的解码 和 HS-DSCH数据接收的问题。 而且根据实际需要对 HS-SCCH与 HS-DSCH资源之间固定间隔进行调整， 避免了网络侧设备为不同类 型 UE分配不同资源时 HS-SICH的冲突问题。
本发明实施例六提供一种用户设备 UE, 如图 14所示， 包括： 获取模块 1401 , 用于根据 HS-SCCH获取 HS-DSCH所在时隙。 其中， 所述获取模块 1401具体用于对所述 HS-SCCH进行解码， 并根据所述解码后的 HS-SCCH获取 HS-DSCH所在时隙； 所述解码 后的 HS-SCCH中携带了所述 HS-DSCH所在时隙的信息。

其中， 所述确定模块 1402具体用于当所述 HS-DSCH所在时隙 只包含时隙 0时， 确定所述 HS-DSCH所在子帧为所述 HS-SCCH所 在子帧 N的下下一个子帧 N+2;当所述 HS-DSCH所在时隙包含时隙 0和其他时隙时，确定时隙 0的 HS-DSCH所在子帧为所述 HS-SCCH 所在子帧 N的下下一个子帧 N+2;其它时隙的 HS-DSCH所在子帧为 所述 HS-SCCH所在子帧 N的下一个子帧 N+l。
接收模块 1403 , 用于在所述 HS-DSCH所在子帧中的 HS-DSCH 所在时隙接收来自所述网络侧设备的 HS-DSCH;
发送模块 1404, 用于在 HS-SICH上向所述网络侧设备返回响应 信息。
其中， 所述发送模块 1404具体用于当所述 HS-DSCH所在时隙 中不包含时隙 0 时， 在 HS-DSCH 所在子帧的下下一个子帧的 HS-SICH上向所述网络侧设备返回响应信息； 或， 当所述 HS-DSCH 所在时隙中包含时隙 0时， 在所述时隙 0对应的 HS-DSCH所在子帧 的下一个子帧的 HS-SICH上向所述网络侧设备返回响应信息。
另外， 在 HS-SICH上向所述网络侧设备返回响应信息时， 所述 HS-DSCH中的最后一个 HS-DSCH和对应的 HS-SICH之间有不小于 8的时隙偏移。
其中， 本发明实施例的装置的各个模块可以集成于一体， 也可以 分离部署。 上述模块可以合并为一个模块， 也可以进一步拆分成多个 子模块。
