无线通信技术领域中, 传输的数据需要占据一定的物理资源。 发送 端在该物理资源上传输数据之前, 需要使接收端获知传输数据采用的物 理资源, 从而接收端才能在正确的物理资源上接收传输的数据。 也就是 说, 发送数据之前, 发送端需要向接收端指示该数据占用的物理资源。
例如, 传输数据的业务信道, 需要由控制信道指示该业务信道上传 输数据的物理资源。 以 TD-SCDMA系统中的高速下行分组接入 ( High Speed Downlink Packet Access, HSDPA ) 为例, 物理资源包括码道、 时 隙(Time Slot, TS )等。 目前的标准中规定, 高速物理下行共享物理信 道( High Speed Physical Downlink Shared CHannel, HS-PDSCH ), 可以 配置在时隙 2至时隙 6上, 而使用高速共享控制信道(Shared Control Channel for HS-DSCH, HS-SCCH ) 的控制格式中的 5个比特指示位于 的时隙。 HS-SCCH上通过时隙信息 ( Time slot information ) 字段指示, 该字段可以如图 1所示, 其中, 标识为 TS2到 TS6的 5个比特, 用于指 示 HS-PDSCH将占用时隙 2到 6中的哪些时隙。
TD-SCDMA系统中, TS0—般配置为公共信道。公共信道大多不进 行功率控制或者波束赋形, 因此, 其发射功率一般较大。 此外, 由于公 共信道的全向发射以及较高的发射功率, 如果 TS0配置其它物理信道, 将会受到严重的干扰。 正是基于上述考虑, 在 HSDPA技术中, 仅考虑 将 HS-PDSCH的物理资源配置在 TS2至 TS6上。
随着技术的发展, 为了减小小区间干扰以及提升小区容量, 从而提 出了 N频点的方式。 N频点系统中, 一个载波作为主载波, 其它载波作 为辅载波。公共信道配置在主载波 TS0上, 而目前辅载波的 TS0并不配 置业务信道。 辅载波空闲的 TS0占用的资源也比较多, 对于资源受限的 TD-SCDMA 系统来说, 浪费了大量的资源。 而随着设备支持多载波能 力的增加, 现有技术中开始考虑要将业务信道扩展到辅载波的 TS0。
在对现有技术的研究和实践过程中, 发明人发现现有技术中存在以 下问题:
对于将业务信道扩展到 TS0上,现有技术还没有相应地物理资源指 示方案。 例如对于 HSDPA来说, 如果将 HS-PDSCH配置到 TS0, 现有 的 HS-SCCH还不支持此种资源配置指示。 发明内容
本发明实施例的目的是提供一种物理资源指示方法及基站, 以实现 指示配置在 TS0上的业务信道。
为解决上述技术问题, 本发明实施例提供一种物理资源指示方法及 基站和无线网络控制器是这样实现的:
一种物理资源指示方法, 该方法包括基站与用户终端预先约定下行 控制信道的控制格式中用于指示时隙 0的信息位, 该方法还包括:
基站采用下行控制信道的所述信息位指示业务信道承载于时隙 0 上;
基站将业务信道承载于时隙 0上进行与用户终端之间的数据传输。 一种基站, 包括:
指示单元, 用于与用户终端预先约定下行控制信道的控制格式中指 示时隙 0的信息位, 采用所述信息位指示业务信道^载于时隙 0上; 传输单元, 用于将业务信道承载于时隙 0上进行与用户终端之间的 数据传输。
由以上本发明实施例提供的技术方案可见, 网络侧与用户终端预先 约定下行控制信道的控制格式中用于指示时隙 0的信息位, 基站采用下 行控制信道的所述信息位指示所述业务信道承载于时隙 0上, 基站将业 务信道承载于时隙 0上进行传输, 这样, 可以实现指示配置在 TS 0上的 业务信道。 附图简要说明

本发明实施例提供一种物理资源指示方法及基站。
为了使本技术领域的人员更好地理解本申请中的技术方案, 下面将 结合本申请实施例中的附图, 对本申请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申请一部分实施例, 而不 是全部的实施例。 基于本申请中的实施例, 本领域普通技术人员在没有 作出创造性劳动前提下所获得的所有其他实施例, 都应当属于本发明保 护的范围。
以下介绍本发明物理资源指示方法的一个实施例。
该实施例中, 需要网络侧与用户终端预先约定下行控制信道的控制 格式中用于指示时隙 0的信息位。 网络侧与用户终端预先约定信息位, 具体为网络侧的基站与用户终端预先约定信息位。
例如, 以 TD-SCDMA中的 HSDPA为例, 在现有技术 HS-SCCH的 控制格式的基础上,将图 1中原本指示 TS2至 TS6的某个比特位重新定 义为指示 TS0的信息位。
在网络侧与用户终端预先约定下行控制信道的控制格式中用于指 示时隙 0的信息位之后, 本发明物理资源指示方法一实施例的流程可以 如图 2所示, 包括:
S210: 基站采用下行控制信道的所述信息位指示业务信道承载于时 隙 0上。
前述由于网络侧与 UE已预先约定了下行控制信道的控制格式中用 于指示时隙 0的信息位, 因此, 在 S210中, 可以采用下行控制信道的 该信息位来指示所述业务信道承载于时隙 0上。
S220: 基站将业务信道承载于时隙 0上进行传输。
如前所述, 该步骤中, 基站将业务信道承载于时隙 0上进行传输, 如以 TD-SCDMA中的 HSDPA为例,将业务信道 载于辅载波的时隙 0 上进行传输, 即可以将 HS-PDSCH承载于某个辅载波的 TS0上传输; 此时, 所述下行控制信道的控制格式为高速下行分组接入中 HS-SCCH 中的时隙信息, 所述业务信道为 HS-PDSCH。 需要说明的是, 上述方法实施例, 可以适用于多载波系统。 多载波 系统中, 一个载波作为主载波, 其它作为辅载波, 一般地, 允许将业务 信道配置在辅载波的 TS0上传输, 则可以采用上述方法实施例, 以通知 UE业务信道^载于辅载波的时隙 0上。 另外, 上述方法实施例, 对于 系统中采用单载波, 而下行业务信道配置在该单载波的 TS0上传输的情 况, 也可以适用, 即也可以采用上述方法实施例来指示在单载波的 TS0 上配置的业务信道。
这里的网络侧与 UE事先预定下行控制信道的控制格式中用于指示 时隙 0的信息位, 包括两层意思:
情况 1、 网络侧预置下行控制信道的控制格式中用于指示时隙 0的 信息位, UE中也预置下行控制信道的控制格式中用于指示时隙 0的信 息位。 当然, 网络侧预置的下行控制信道的控制格式中用于指示时隙 0 的信息位与 UE中预置的相同。 在网络侧预置下行控制信道的控制格式 中用于指示时隙 0的信息位, 也就是, 在网络侧的基站预置下行控制信 道的控制格式中用于指示时隙 0的信息位。 在网络侧和 UE预置下行控 制信道的控制格式中用于指示时隙 0的信息位, 也就是在网络侧和 UE 按照预先的规定各自分别进行设置下行控制信道的控制格式中用于指 示时隙 0的信息位。
情况 2、 网络侧预先确定下行控制信道的控制格式中用于指示时隙 0的信息位, 并通知给 UE。
对于网络侧, 上述预先约定的下行控制信道的控制格式中用于指示 时隙 0的信息位, 可以是由网络侧的 RNC确定, 并通知网络侧的基站。 特别的, 在上面的第 2种情况中, RNC还将预先确定下行控制信道的控 制格式中用于指示时隙 0的信息位通知给 UE。 通知 UE的内容中, 在 TD-SCDMA的 HSDPA中, 包括预先通知 UE HS-SCCH的控制格式的 5 个时隙指示比特中某一比特用于指示 HS-PDSCH是否承载于时隙 0。 RNC可以为小区中所有的 HS-SCCH统一配置时隙信息中某个时隙指示 信息位用于指示 HS-PDSCH 是否承载于时隙 0 , 也可以为每一条 HS-SCCH独立配置。 RNC预先确定下行控制信道的控制格式中用于指 示时隙 0的信息位的情况, RNC可以是在 RNC发给基站的物理共享信 道重配 ( PHYSICAL SHARED CHANNEL RECONFIGURATION ) 消息 中增加信令来指示, 从而通知给基站。 RNC 可以通过无线资源控制 ( Radio Resource Control, RRC )信令通知 UE预先确定的下行控制信 道的控制格式中用于指示时隙 0的信息位的情况。 RNC也可以通过在广 播消息中增加信令来指示, 以通知 UE预先确定的下行控制信道的控制 格式中用于指示时隙 0的信息位的情况。
另外, 上述网络侧与 UE预先约定的下行控制信道的控制格式中用 于指示时隙 0的信息位, 也可以是由基站确定。 基站预先确定下行控制 信道的控制格式中用于指示时隙 0 的信息位, 反馈给 RNC。 以 TD-SCDMA中的 HSDPA为例, 基站预先确定 UE对应的 HS-SCCH上 的某个时隙指示信息位代表 HS-PDSCH是否承载于时隙 0后, 反馈给 RNC。 特别的, 在上面的第 2种情况中, RNC还将预先确定的下行控制 信道的控制格式中用于指示时隙 0的信息位通知给 UE,如前述通过 RRC 信令通知。 通知 UE的内容中, 以 TD-SCDMA中的 HSDPA为例, 可以 包括预先通知 UE HS-SCCH的控制格式的 5个时隙指示比特中某一比特 用于指示 HS-PDSCH是否承载于时隙 0。 基站可以为该 UE对应的一组 HS-SCCH统一配置某个时隙指示信息位对应的具体下行时隙号, 也可 以为该 UE对应的每一条 HS-SCCH独立配置。 以下给出上述实施例的第一具体例子,该例子以上面的情况 2为例, 并仍以 TD-SCDMA中的 HSDPA为例加以说明:
首先,网络侧预先通知 UE HS-SCCH的控制格式的 5个时隙指示比 特中某一比特用于指示 HS-PDSCH是否承载于时隙 0。
总的来说,网络侧的 RNC与 UE之间使用 6个比特的信令表示分别 对应时隙号的情况下, 网络侧的 RNC可以使用这 6个比特的信令通知 UE HS-SCCH上的 5比特时隙信息分别对应的时隙号。 这 6个比特可以 分别对应 TS0、 TS2、 TS3、 TS4、 TS5 和 TS6。 对应的比特为 1 表示 HS-SCCH可以指示 HS-PDSCH 配置在该时隙; 对应的比特为 0表示 HS-PDSCH 不会配置在该时隙, 相应地, HS-SCCH 也不会指示 HS-PDSCH配置在该时隙上。 当然, 这 6个比特中, 一般至多会有 5个 比特为 1 , 从而对应 HS-SCCH的时隙信息字段上指示时隙的 5个比特 位分别表示的时隙。 HS-SCCH上时隙信息的 5个时隙指示比特可以顺 序指示对应信令设置为 1的那些时隙。
比如: 这 6比特的信令配置为 '101111,, 则 HS-SCCH上的 5比特 时隙信息, 顺序对应 TS0、 TS3、 TS4、 TS5和 TS6; 该情况下, 图 1所 示的字段指示的时隙将变为如图 3所示。
比如: 这 6比特的信令配置为 '111110,, 则 HS-SCCH上的 5比特 时隙信息, 顺序对应 TS0、 TS2、 TS3、 TS4和 TS5。
比如: 这 6比特的信令配置为 '101100,, 则 HS-SCCH上的 5比特 时隙信息中的前 3个比特, 顺序对应 TS0、 TS3和 TS4; 后两个比特无 意义, 可以作为保留位。 该情况下, 图 1所示的字段指示的时隙将变为 如图 4所示。
这样, 基站采用下行控制信道的指示时隙 0的信息位指示所述业务 信道承载于时隙 0上, 进而可以将业务信道承载于时隙 0上进行传输。
此外, 上述 6个比特指示的 HS-SCCH的时隙信息字段上表示时隙 的 5个比特位所分别表示的时隙, 可以是由 RNC确定, 并通知基站及 UE。 通知 UE的内容中, 具体的包括预先通知 UE HS-SCCH的控制格 式的 5个时隙指示比特中某一比特用于指示 HS-PDSCH是否承载于时隙 0。 RNC可以为小区中所有的 HS-SCCH统一配置 5个时隙指示信息位 对应的具体下行时隙号, 也可以为每一条 HS-SCCH独立配置。 RNC通 知基站预先确定的下行控制信道的控制格式中用于指示时隙 0 的信息 位, 具体可以是在 RNC 发给基站的物理共享信道重配 (PHYSICAL SHARED CHANNEL RECONFIGURATION ) 消息中增加信令来指示。 RNC可以通过 RRC信令通知 UE预先确定的下行控制信道的控制格式 中用于指示时隙 0的信息位的情况。 RNC也可以通过在广播消息中增加 信令来指示, 以通知 UE预先确定的下行控制信道的控制格式中用于指 示时隙 0的信息位的情况。
另外, 上述 6个比特指示的 HS-SCCH的时隙信息字段上表示时隙 的 5个比特位所分别表示的时隙, 可以是由基站确定。 基站确定 UE对 应的 HS-SCCH上的 5个时隙指示信息位代表的具体下行时隙号后, 反 馈给 RNC , 并由 RNC通知 UE, 具体的如采用前述的 RRC信令通知。 通知 UE的内容中, 具体的, 包括预先通知 UE HS-SCCH的控制格式的 5个时隙指示比特中某一比特用于指示 HS-PDSCH是否承载于时隙 0。 基站可以为该 UE对应的一组 HS-SCCH统一配置 5个时隙指示信息位 对应的具体下行时隙号, 也可以为该 UE对应的每一条 HS-SCCH独立 配置。 基站确定的 HS-SCCH的时隙信息字段上表示时隙的 5个比特位 分别表示的时隙。 以下给出上述实施例的第二具体例子, 该例子以上面的情况 2为例 进行说明。 仍以 TD-SCDMA中的 HSDPA为例加以说明: 网络侧的 RNC仍然预先通知 UE HS-SCCH的控制格式的 5个时隙 指示比特中某一比特用于指示 HS-PDSCH是否承载于时隙 0。
总的来说, 网络侧的 RNC与 UE之间采用比特位图 ( bitmap )形式 的信令表示对应时隙号的情况下,网络侧可以采用该 bitmap形式的信令 通知 UE HS-SCCH上的 5比特时隙信息分别对应的时隙号。
具体地, RNC和 UE分别保存了比特映射对应关系, 所述比特映射 对应关系包括 bitmap与时隙号之间的对应关系,所述时隙号包括时隙 0。 之后, RNC通过 bitmap将所述信息位通知给 UE, 具体地: RNC将至 少一个 bitmap通知给 UE, 用户接收 bitmap之后, 便可在所述比特映射 对应关系中查找出相应的时隙号。
例如, 采用 6bit的 bitmap来表示对应的时隙号如下面表 1所示:
Figure imgf000011_0001
表 1. 6bit的 bitmap表
这样, 网络侧的 RNC可以采用上述表 1中的至 bitmap通知
UE。 具体的, 网络侧的 RNC例如通知 UE:
HS-SCCH 的时隙信息中的比特 1 对应 表 1 中第一个 bitmap '100000' 所代表的时隙, 即时隙 0;
HS-SCCH 的时隙信息中的比特 2 对应 表 1 中第三个 bitmap '001000' 所代表的时隙, 即时隙 3;
HS-SCCH 的时隙信息中的比特 3 对应 表 1 中第四个 bitmap '000100' 所代表的时隙, 即时隙 4;
HS-SCCH 的时隙信息中的比特 4 对应 表 1 中第五个 bitmap '000010' 所代表的时隙, 即时隙 5;
HS-SCCH 的时隙信息中的比特 5 对应 表 1 中第六个 bitmap ΌΟΟΟΟΙ' 所代表的时隙, 即时隙 6。
按照表 1中的对应关系, UE从而可以得知 HS-SCCH上的 5个时隙 信息分别对应 TS0、 TS3、 TS4、 TS5和 TS6。 该情况下, 图 1所示的字 段指示的时隙将变为如图 3所示。
再例如, 采用 3bit的 bitmap来表示 HS-SCCH上的 5个比特时隙信 息分别对应的时隙号, 如下面表 2所示:
Figure imgf000012_0001
表 2. 3bit的 bitmap表
这样, 网络侧可以采用上述表 2中的至多 5个 bitmap通知 UE。 具 体的, 网络侧例如通知 UE:
HS-SCCH的时隙信息中的比特 1对应,表 2中第一个 bitmap '000, 所代表的时隙, 即时隙 0;
HS-SCCH的时隙信息中的比特 2对应,表 2中第三个 bitmap '010, 所代表的时隙, 即时隙 3;
HS-SCCH的时隙信息中的比特 3对应,表 2中第四个 bitmap '011, 所代表的时隙, 即时隙 4;
HS-SCCH的时隙信息中的比特 4对应,表 2中第五个 bitmap '100, 所代表的时隙, 即时隙 5;
HS-SCCH的时隙信息中的比特 5对应,表 2中第六个 bitmap '101' 所代表的时隙, 即时隙 6。
那么按照表 2中的对应关系, UE从而可以得知 HS-SCCH上的 5个 时隙信息分别对应 TS0、 TS3、 TS4、 TS5和 TS6。 该情况下, 图 1所示 的字段指示的时隙将变为如图 3所示。
网络侧无论采用表 1中的 bitmap还是表 2中的 bitmap通知 UE, 都 可以指示 HS-SCCH上的 5个时隙信息中对应 TS0的时隙。 这样, 基站 采用下行控制信道的指示时隙 0的信息位指示所述业务信道 载于时隙 0上, 并将业务信道承载于时隙 0上进行传输, 进而 UE可以在时隙 0 上接收业务信道。
具体的, 上述 bitmap指示的 HS-SCCH的时隙信息字段上表示时隙 的 5个比特位分别表示的时隙, 网络侧的 RNC可以通过在无线资源控 制 (Radio Resource Control, RRC )信令增加信令的方式来通知 UE上 述内容, 也可以是 RNC通过在广播消息中增加信令的方式来携带上述 内容。
此外, 上述 bitmap指示的 HS-SCCH的时隙信息字段上表示时隙的
5个比特位所分别表示的时隙,可以是由 RNC确定,并通知基站及 UE。 通知 UE的内容中, 具体的, 包括预先通知 UE HS-SCCH的控制格式的 5个时隙指示比特中某一比特用于指示 HS-PDSCH是否承载于时隙 0。 RNC可以为小区中所有的 HS-SCCH统一配置时隙信息中某个时隙指示 信息位用于指示 HS-PDSCH 是否承载于时隙 0 , 也可以为每一条 HS-SCCH独立配置。 RNC通知基站预先确定的下行控制信道的控制格 式中用于指示时隙 0的信息位, 具体可以是在 RNC发给基站的物理共 享信道重配 ( PHYSICAL SHARED CHANNEL RECONFIGURATION ) 消息中增加信令来指示。 RNC可以通过 RRC信令通知 UE预先确定的 下行控制信道的控制格式中用于指示时隙 0的信息位的情况。 RNC也可 以通过在广播消息中增加信令来指示, 以通知 UE预先确定的下行控制 信道的控制格式中用于指示时隙 0的信息位的情况。
另外, 上述 bitmap指示的 HS-SCCH的时隙信息字段上表示时隙的 5个比特位所分别表示的时隙, 可以是由基站确定。 基站确定 UE对应 的 HS-SCCH上的 5个时隙指示信息位代表的具体下行时隙号后, 反馈 给 RNC, 并由 RNC通知 UE, 具体的如采用前述的 RRC信令通知。 通 知 UE的内容中, 具体的, 包括预先通知 UE HS-SCCH的控制格式的 5 个时隙指示比特中某一比特用于指示 HS-PDSCH是否承载于时隙 0。 基 站可以为该 UE对应的一组 HS-SCCH统一配置 5个时隙指示信息位对 应的具体下行时隙号, 也可以为该 UE对应的每一条 HS-SCCH独立配 置。 基站确定的 HS-SCCH的时隙信息字段上表示时隙的 5个比特位分 别表示的时隙。 以下给出上述实施例的第三具体例子, 该例子以上面的情况 2为例 进行说明, 并仍以 TD-SCDMA中的 HSDPA为例加以说明:
在配置时, 可以将 HS-SCCH所在时隙与 HS-PDSCH所在时隙配置 在同一时隙, 也可以不配置在同一时隙。 如果预先约定配置 HS-SCCH 所在时隙与 HS-PDSCH所在时隙不为同一时隙的情况下,网络侧便可以 预先通知 UE HS-SCCH上的时隙信息中与 HS-SCCH所在时隙号对应的 时隙指示信息位用于指示 HS-PDSCH是否承载于时隙 0。
例如, 预先约定配置 HS-SCCH所在时隙与 HS-PDSCH所在时隙不 为同一时隙。 按照该预先约定, 一个例子中, 如果配置 HS-SCCH所在 时隙为时隙 6, 则 HS-PDSCH 将不会再被配置在时隙 6 上。 此时, HS-SCCH 中时隙信息指示时隙 6的比特将不再有意义。 因此, 可以利 用该指示时隙 6的时隙指示信息位来表示 HS-PDSCH是否承载于时隙 0。
这样, 基站采用下行控制信道的指示时隙 0的信息位指示所述业务 信道^ ^载于时隙 0上, 并将业务信道 载于时隙 0上进行传输后, 进而 UE可以在时隙 0上接收业务信道。 如上面的例子, 可以利用 HS-SCCH 中的原来指示时隙 6的时隙指示信息位来表示 HS-PDSCH承载于时隙 0。
此外, 上述预先约定配置 HS-SCCH所在时隙与 HS-PDSCH所在时 隙不为同一时隙, 以及时隙信息中与 HS-SCCH所在时隙号对应的时隙 指示信息位用于指示 HS-PDSCH是否承载于时隙 0, 可以是由 RNC确 定, 并通知基站及 UE。 具体的, 例如 HS-SCCH所在时隙为时隙 6, 而 HS-PDSCH将不会再被配置在时隙 6上, 则可以采用 1 个比特来指示 UE上述内容, 例如: 1比特的信息如果为 1 , 可以表示 HS-SCCH的控 制格式的 5 个时隙指示比特中原来指示时隙 6 的比特用于指示 HS-PDSCH是否承载于时隙 0。 RNC可以为小区中所有的 HS-SCCH统 一配置时隙信息中某个时隙指示信息位用于指示 HS-PDSCH是否承载 于时隙 0, 也可以为每一条 HS-SCCH独立配置。
另外, 上述预先约定配置 HS-SCCH所在时隙与 HS-PDSCH所在时 隙不为同一时隙, 以及时隙信息中与 HS-SCCH所在时隙号对应的时隙 指示信息位用于指示 HS-PDSCH是否承载于时隙 0, 也可以是由基站确 定。 基站确定 UE 对应的 HS-SCCH 上的某个时隙指示信息位代表 HS-PDSCH是否承载于时隙 0后, 反馈给 RNC, 并由 RNC通知 UE, 具体的如采用前述的 RRC信令通知。 具体的, 仍以上面 HS-SCCH所在 时隙为时隙 6, 而 HS-PDSCH将不会再被配置在时隙 6为例, 则通知 UE的内容包括采用 1个比特指示的 HS-SCCH的控制格式的 5个时隙指 示比特中原来指示时隙 6的比特用于指示 HS-PDSCH是否承载于时隙 0。 以下给出上述实施例的第四具体例子, 该例子以上面的情况 2为例 进行说明, 并仍以 TD-SCDMA中的 HSDPA为例加以说明:
网络侧仍然预先通知 UE HS-SCCH的控制格式的 5个时隙指示比特 中某一比特用于指示 HS-PDSCH是否承载于时隙 0。
现有技术中,用于通知 UE HS-SCCH的控制格式的 5个时隙指示比 特,是用于指示配置 HS-PDSCH资源的情况, 这 5个时隙指示比特用于 指示 TS2、 TS3、 TS4、 TS5和 TS6这 5个时隙。 实际中, 存在不会将所 有的这 5个时隙都配置作为 HS-PDSCH资源的情况,相应地, 用于通知 UE HS-SCCH的控制格式的 5个时隙指示比特中将存在空闲, 此时: 用 于指示 HS-PDSCH是否承载于时隙 0的 5个时隙指示比特中的 1个比特, 可以是没有配置作为 HS-PDSCH资源的那个时隙对应的时隙指示比特。
例如, 没有配置作为 HS-PDSCH资源的时隙为时隙 6, 则可以预先 通知 UE HS-SCCH的控制格式的 5个时隙指示比特中原来用于指示时隙 6的比特用于指示 HS-PDSCH是否承载于时隙 0。
这样, 基站采用下行控制信道的指示时隙 0的信息位指示所述业务 信道^载于时隙 0上, 并将业务信道 载于时隙 0上进行传输后, 进而 UE可以在时隙 0上接收业务信道。 如上面的例子, 可以利用 HS-SCCH 中的原来指示时隙 6的时隙指示信息位来表示 HS-PDSCH承载于时隙 0。
此外,上述预先通知 UE HS-SCCH的控制格式的 5个时隙指示比特 中某一比特用于指示 HS-PDSCH是否承载于时隙 0, 可以是由 RNC确 定, 并通知基站及 UE。 通知 UE的内容中, 具体的, 包括预先通知 UE HS-SCCH 的控制格式的 5 个时隙指示比特中某一比特用于指示 HS-PDSCH是否承载于时隙 0。 RNC可以为小区中所有的 HS-SCCH统 一配置时隙信息中某个时隙指示信息位用于指示 HS-PDSCH是否承载 于时隙 0, 也可以为每一条 HS-SCCH独立配置。 RNC通知基站预先确 定的下行控制信道的控制格式中用于指示时隙 0的信息位, 具体可以是 在 RNC发给基站的物理共享信道重配( PHYSICAL SHARED CHANNEL RECONFIGURATION )消息中增加信令来指示。 RNC可以通过 RRC信 令通知 UE预先确定的下行控制信道的控制格式中用于指示时隙 0的信 息位的情况。 RNC 也可以通过在广播消息中增加信令来指示, 以通知 UE预先确定的下行控制信道的控制格式中用于指示时隙 0的信息位的 情况。 由上述实施例可见, 网络侧与用户终端预先约定下行控制信道的控 制格式中用于指示时隙 0的信息位, 基站采用下行控制信道的所述信息 位指示所述业务信道承载于时隙 0上, 基站将业务信道承载于时隙 0上 进行传输, 这样, 可以实现指示配置在 TS0上的业务信道。 以下介绍本发明一基站实施例, 图 5 , 包括:
指示单元, 用于与用户终端预先约定下行控制信道的控制格式中指 示时隙 0的信息位, 采用所述信息位指示业务信道^载于时隙 0上; 传输单元, 用于将业务信道承载于时隙 0上进行与用户终端之间的 数据传输。
指示单元与用户终端预先约定下行控制信道的控制格式中指示时 隙 0的信息位, 包括两层意思, 具体参见前述关于方法部分的描述。
优选地, 所述时隙 0包括多载波系统中辅载波的时隙 0或单载波系 统中的时隙 0。
优选地, 所述指示单元还包括反馈子单元, 当预先约定的所述信息 位由基站确定时, 所述反馈子单元用于将确定的所述信息位反馈给无线 网络控制器。
