为使上述上行反馈方法更具体, 下面将针对连续的至少两个下行子帧为 子帧为多载波上的连续的至少两个下行子帧的实施场景分别对本发明提供的 上行反馈方法进行说明。
在连续的至少两个下行子帧为单载波实施场景下
本实施例以无线帧为例, 无线帧的周期是 20ms, 其中下行子帧的长度为 2ms, 上行子帧的长度为 4ms。 图 2为本发明无线帧上行反馈的示意图, 如图 2所示, 图中, HS-SCCH为高速共享控制信道, HS-DSCH NB为基站的高速 下行链路共享信道, HS-DSCH UE 为用户设备的高速下行链路共享信道, HS-DPCCH UE 为用户设备的高速专用物理上行反馈控制信道, HS-DPCCH NB为基站的高速专用物理上行反馈控制信道。
一个上行反馈 HS-DPCCH子帧对连续的两个 HS-DPCCH下行子帧进行 联合反馈。 对于该情形下的混合自动重传请求 ( Hybrid Automatic Repeat Request, 简称 HARQ )反馈的码本釆用双载波制 (DC, Dual Carrier )联合 反馈码本, 即, 联合上行反馈信息可以通过 DC联合反馈码本确定。 本实施 例以单载波上连续的两个下行子帧的长度之和等于一个上行子帧的长度为 例, 具体地, 分为以下几种实施场景:
当基站向用户设备发送下行数据, 用户设备只接收到第一个传输时间间 隙( Transmission Time Interval, 简称 TTI )或子帧的 HS-SCCH时, 使用反馈 码本格式如表一: ACK 1 1 1 1 1 1 1 1 1 1
NACK 0 0 0 0 0 0 0 0 0 0 当基站向用户设备发送下行数据, 用户设备只接收到第二个 TTI或子帧 S-SCCH时, 使用反馈码本格式如表二:
Figure imgf000012_0001
当基站向用户设备发送下行数据, 用户设备接收到了两个 TTI或子帧的 HS-SCCH时, 第一个子帧或 ΤΉ与第二个子帧或 ΤΉ进行联合反馈,使用反 馈码本格式如表三, 表格中第一列表示第一个子帧或 TTI的反馈信息, 第二 列表示第二个子帧的反馈信息。
上述表一和表二的反馈码本可用于互换, 即将表二码本用于第一个子帧 I的反馈, 将表一码本用于第二个子帧或 TTI的反馈。
Figure imgf000012_0002
子帧来确定的。 比如, 当连续两个子帧联合反馈时, 根据第二个子帧进行反
之间可以通过约定来确定联合反馈, 或者通过 RNC通知 UE和基站需要将主 小区的连续子帧与辅小区的子帧进行联合反馈的方式, 或者基站可以通过指 示消息通知 UE需要将小区的连续子帧进行联合反馈。 对于后两种方式, 网 络侧可在确定 UE能支持对连续的子帧进行联合反馈后,再指示 UE对连续子 帧进行联合反馈。
具体的,对于通过 RNC通知 UE和基站需要将主小区的连续子帧与辅小 区的子帧进行联合反馈的方式, UE上报具有支持对连续的子帧进行联合反馈 的能力给 RNC, RNC通知基站 UE具备该能力, 或指示基站按照连续子帧的 联合反馈来解读 UE的反馈信息。对于 RNC指示使用连续子帧的联合反馈方 法, 可选地, 还可指示联合反馈的子帧信息, 该信息至少包含以下信息之一: 子帧个数, 至少两个子帧号。
对于基站可以通过指示消息通知用户设备需要将小区的连续子帧进行联 合反馈的方式, UE上报具有支持对连续的子帧进行联合反馈的能力给 RNC, RNC通知基站 UE具备该能力,基站指示 UE使用连续子帧的联合反馈方法。 进一步, 还可指示联合反馈的子帧信息, 该信息至少包含以下信息之一: 子 帧个数, 至少两个子帧号。
网络侧可配置对于连续子帧反馈所使用的码本。 进一步, 可以指示在只 收到第一个子帧、 只收到第二个子帧、 收到两个子帧进行反馈编码时所使用 的反馈码本, 具体指上述表一、 表二、 表三。
上述单载波的配置方式可同样适用于双载波或多载波场景的配置。
以下以连续的至少两个下行子帧为双载波实施场景为例进行说明: 图 3为本发明实施例二双载波情形一的示意图。 如图 3所示, 在本实施 例中, 连续的至少两个下行子帧包括主小区的一个下行子帧和辅小区的连续 的两个下行子帧。
主小区的一个下行子帧和辅小区的连续两个下行子帧联合编码进行反 馈, 用户设备和基站之间可以通过预先协商确定联合反馈, 或者基站或 RNC 可以通过指示消息通知用户设备需要将辅小区的连续子帧与主小区的子帧进 行联合反馈。 具体地, 上行反馈的数据格式有以下两种, 如表四和表五所示, 其中, DC case表示双载波场景, Cell activation status表示小区激活状态, - 表示去激活, 即禁用联合反馈功能, Cell 1表示主小区, Cell 2表示辅小区, Sub-frame表示子帧, HS-DPCCH sub-frame#l表示高速专用物理控制信道子 帧, Slot表示时隙, A表示 ACK, D表示不连续发送, CQI表示信道质量指 示符。
