Description

三载波模式下发送反馈控制信息的方法、 装置及终端设备
技术领域 本发明涉及移动通信领域, 特别涉及 WCDMA系统三载波模式下发送 高速专用物理控制信道的方法、 装置及终端设备。 背景技术 随着通信技术的飞速发展, WCDMA ( Wideband Code Division Multiple Access,宽带码分多址接入)系统作为第三代移动通信系统的主流技术之一, 在全球范围内得到了广泛的研究和应用。
WCDMA系统中的一个研究重点是多载波设计, WCDMA系统的不同 载波上的数据流可以看成和多天线类似的数据流。 采用多个载波的 WCDMA系统中,用户终端可能需要多个 HS-DPCCH( High-Speed Dedicated Physical Control Channel, 高速专用物理控制信道)信道向基站发送各个载 波的反馈控制信息。其中,反馈控制信息主要包括: ACK( Acknowledgment, 确认指示)/NACK( No Acknowledgment,非确认指示)、 CQI( channel quality indicator , 信道质量指示)。
当 WCDMA系统采用三载波模式时, 现有技术中一种发送反馈控制信 息的方式是使用三个 HS-DPCCH信道,每个 HS-DPCCH信道发送一个载波 的 ACK/NACK和 CQI。
本发明的发明人在实现本发明过程中发现: 在三载波模式下采用三个 HS-DPCCH信道同时发送这些反馈控制信息, 会引起 CM ( Cubic Metrics, 立方度量)值的增大, 从而降低基站的覆盖范围。 发明内容 有鉴于此, 本发明实施例在于提供一种三载波模式下发送反馈控制 信息的方法、 装置及终端设备, 以降低 CM值, 提高基站的覆盖范围。 本发明实施例提供一种三载波模式下发送反馈控制信息的方法, 该 方法包括: 在一个高速专用物理控制信道 HS-DPCCH 上发送三个载波的反馈 控制信息; 其中, 所述 HS-DPCCH每个 2毫秒 ms子帧的第 1个时隙发 送三个载波联合编码的确认指示 ACK或非确认指示 NACK, 每个 2ms 子帧的第 2、 3个时隙发送两个载波联合编码的信道质量指示 CQI信息, 并且每三个 2ms传输时间间隔 TTI发送的联合编码的 CQI信息中,每个 载波对应的 CQI信息发送两次。 本发明实施例还提供另一种三载波模式下发送反馈控制信息的方 法, 该方法包括:
在两个 HS-DPCCH 上发送三个载波的反馈控制信息; 其中, 在 HS-DPCCH1上发送两个载波联合编码的 CQI信息, 在 HS-DPCCH2上 发送一个载波单独编码的 CQI 信息, 在所述 HS-DPCCH1 或所述 HS-DPCCH2上发送三个载波联合编码的 ACK或 NACK。 本发明实施例提供一种三载波模式下发送反馈控制信息的装置, 该 方法包括: 单码道发送单元,用于在一个 HS-DPCCH上发送三个载波的反馈控 制信息; 其中, 所述 HS-DPCCH每个 2ms子帧的第一个时隙发送三个 载波联合编码的 ACK或 NACK, 每个 2ms子帧的第 2、 3个时隙发送两 个载波联合编码的 CQI信息,并且每三个 2msTTI发送的联合编码的 CQI 信息中, 每个载波对应的 CQI信息发送两次。 本发明实施例还提供一种三载波模式下发送反馈控制信息的装置, 该方法包括: 双码道发送单元,用于在两个 HS-DPCCH发送三个载波的反馈控制 信息; 其中, 在 HS-DPCCH1上发送两个载波联合编码的 CQI信息, 在 HS-DPCCH2上发送一个载波单独编码的 CQI信息,在所述 HS-DPCCH1 或所述 HS-DPCCH2上发送三个载波联合编码的 ACK或 NACK。 本发明实施例还提供一种终端设备, 该终端设备包括: 上述单码道 发送单元以及双码道发送单元。
较现有技术相比, 本发明实施例提供的三载波模式下发送反馈控制 信息的方法、 装置以及终端设备, 采用一个或两个 HS-DPCCH发送反馈 控制信息, 可以降低 CM值, 提高基站覆盖范围。 附图说明 图 1为本发明一个实施例的三载波模式下发送反馈控制信息的方法 示意图; 图 2为本发明另一个实施例的三载波模式下发送反馈控制信息的方 法示意图; 图 3为本发明又一个实施例的三载波模式下发送反馈控制信息的装 置结构示意图; 图 4为本发明又一个实施例的三载波模式下发送反馈控制信息的装 置结构示意图;
图 5为本发明一个实施例的终端设备结构示意图。 具体实施方式 以下结合附图和具体实施方式对本发明做进一步详细的说明。 本发明实施例涉及三载波模式下发送反馈控制信息 (比如,
ACK/NACK, CQI ) 的技术。 本发明实施例中, 可以使用一个或两个 HS-DPCCH信道来承载三个载波的反馈控制信息, 以减小 CM值, 提高 基站覆盖范围。 图 1为本发明一个实施例的三载波模式下发送反馈控制信息的方法 示意图。
如图 1 所示, 本实施例中在一个 HS-DPCCH信道(或者称为一个 HS-DPCCH码道)发送三个载波的反馈控制信息。 其中, HS-DPCCH每 个 2ms子帧的第 1个时隙发送三个载波联合编码的 ACK/NACK; 第一 个 2ms子帧第 2、 3个时隙发送载波 1和载波 2联合编码的 CQI信息; 第二个 2ms子帧第 2、 3个时隙发送载波 3和载波 1联合编码的 CQI信 息; 第三个 2ms子帧的第 2、 3个时隙发送载波 2和载波 3联合编码的 CQI信息。 如此, 每 3个 2ms TTI ( Transmission Time Interval, 传输时 间间隔) 周期反复。
当然, 本领域技术人员可以理解的是, 发送联合编码的 CQI信息并 不局限于图 1所示的方式, 还可以有其他的方式。 比如, 每 3个 2ms子 帧第 2、 3个时隙发送两个载波联合编码的 CQI信息依次可以是(载波 1 和载波 2 ) , (载波 2和载波 3 ) , (载波 3和载波 1 ) 的组合, 也可以 是(载波 1和载波 3 ) , (载波 3和载波 1 ) , (载波 2和载波 3 ) 的组 合; 也可以是(载波 2和载波 3 ) , (载波 3和载波 1 ) , (载波 1和载 波 2 ) 的组合等等。 本实施例提供的发送反馈控制信息的方法中, 满足: 每个 2ms子帧 的第 2、 3个时隙发送两个载波联合编码的 CQI信息,并且每 3个 2ms TTI 发送的联合编码的 CQI信息中,每个载波对应的 CQI信息发送两次。 因 此, 本实施例中, 三载波模式下每个载波的 CQI 信息上报周期为 3ms*N—cqi— transmit ( N—cqi— transmit表示 CQI重复上报的次数) 。 本实施例提供的发送反馈控制信息的方法中,在一个 HS-DPCCH码 道发送三个载波的反馈控制信息,可以降低 CM值,提高基站覆盖范围。 另外, 由于每 3个 2ms TTI发送的联合编码的 CQI信息中, 每个载波对 应的 CQI信息发送两次; 因此, 当使用一个 HS-DPCCH码道时, 本实 施例提供的发送反馈控制信息的方法可以使每个载波的 CQI上报周期最 小。 这样, 不仅可以降低 CM值, 提高基站覆盖范围; 还可以提高对各 个载波调度的效率。
另外, 本实施例中还进一步对经过联合编码的第一个 CQI信息定时 关系进行了设计。通常, HS-DPCCH的第一个 CQI信息在对应的 DPCCH ( Dedicated Physical Control Channel, 专用物理控制信道 )帧头 m*256个 chips (码片)后开始上 ·¾。 其中, m表示相对于 DPCCH帧头的时间偏 移, 是 256chips的整数倍。
当 CQI的上报周期 k>=3ms*N—cqi— transmit时, 可以采用实施例提 供的发送反馈控制信息的方法。 本实施例还提供发送 CQI信息的定时关 系的方式, 如公式 (1) - (3) 所示:
(5 X CFN + [mx 256c/z/ /7680c ])mod k =0
( 1)
[(5 x CFN + [mx
Figure imgf000007_0001
0 (2)
[(5 x CFN + [mx 256c /7680c/z/ ) + 2xn] mod k =0
(3) 其中, n=N—cqi— transmit, k'=k/2ms, CFN表示连接帧号 ( Connection Frame Number ) 。
根据本实施例提供的发送反馈控制信息的方法以及上述公式, 一种 发送联合编码的 CQI信息的方式为:
当前的 CQI信息定时关系满足公式 ( 1 ) 时, 发送载波 1和载波 2 联合编码的 CQI信息;
当前的 CQI信息定时关系满足公式 (2 ) 时, 发送载波 3和载波 1 联合编码的 CQI信息;
当前的 CQI信息定时关系满足公式 (3 ) 时, 发送载波 2和载波 3 联合编码的 CQI信息。
当然, 本领域技术人员可以理解的是, 上述 CQI信息所指示的载波 组合可以两两互换, 只要满足每个 2ms子帧的第 2、 3个时隙发送两个 载波联合编码的 CQI信息, 并且每 3个 2ms TTI发送的联合编码的 CQI 信息中, 每个载波对应的 CQI信息发送两次即可。 图 2为本发明另一个实施例的三载波模式下发送反馈控制信息的方 法示意图。
如图 2 所示, 本实施例中在两个 HS-DPCCH 信道 (或者说两个 HS-DPCCH码道)发送三个载波的反馈控制信息。其中, HS-DPCCH1 每 个 2ms 子帧的第 1 个时隙发送三个载波联合编码的 ACK/NACK。 HS-DPCCH1每个 2ms子帧第 2、 3个时隙发送载波 1和载波 2联合编码 的 CQI信息; HS-DPCCH2每个 2ms子帧第 2、 3个时隙发送载波 3单独 编码的 CQI信息。 如此, 每个 2ms TTI周期反复。
当然,本领域技术人员可以理解的是, HS-DPCCH1联合编码的 CQI 信息也可以是对应载波 2和载波 3的, 或者是对应载波 1和载波 3的。 例如, 当 HS-DPCCH1在每个 2ms子帧第 2、 3个时隙发送载波 2和载 波 3联合编码的 CQI信息时, HS-DPCCH2每个 2ms子帧第 2、 3个时隙 就发送载波 1单独编码的 CQI信息。 另外, 三个载波的 ACK/NACK也 可以与一个载波单独编码的 CQI信息在 HS-DPCCH2上发送。 本实施例提供的发送反馈控制信息的方法中,在两个 HS-DPCCH信 道传输三个载波的控制反馈信息, 并且两个载波的 CQI信息采用联合编 码, 另一个载波的 CQI信息是单独编码; 因此, 也可以降低 CM值, 提 高基站覆盖范围。 另外, 本实施例提供的发送反馈控制信息的方法, 可 以使三载波模式下每个载波的 CQI 信息上报周期最小缩短为 2ms*N—cqi— transmit, 提高了对各个载波调度的效率。 本领域技术人员可以理解的是, 在三载波模式下, 可以根据 CQI上 报周期的要求, 灵活采用以上实施例提供的发送反馈控制信息的方法。 比如, 如果 CQI上报周期 k=2ms*N—cqi— transmit, 则可以按照图 2所示 的发送方法上 CQI信息; 如果 CQI上4艮周期 k>=3ms*N—cqi— transmit, 则可以按照图 1所示的发送方法上报 CQI信息。 图 3为本发明一个实施例的三载波模式下发送反馈控制信息的装置 结构示意图。如 3所示,该三载波模式下发送反馈控制信息的装置包括: 单码道发送单元 30, 用于在一个 HS-DPCCH上发送三个载波的反 馈控制信息; 其中, 所述 HS-DPCCH每个 2ms子帧的第一个时隙发送 三个载波联合编码的 ACK或 NACK, 每个 2ms子帧的第 2、 3个时隙发 送两个载波联合编码的 CQI信息, 并且每三个 2msTTI发送的联合编码 的 CQI信息中, 每个载波对应的 CQI信息发送两次。 单码道发送单元 30在一个 HS-DPCCH上发送三个载波的反馈控制 信息的一种方式如下: 单码道发送单元 30用于在 HS-DPCCH每个 2ms子帧的第 1个时隙 发送三个载波联合编码的 ACK/NACK; 第一个 2ms子帧第 2、 3个时隙 发送载波 1和载波 2联合编码的 CQI信息; 第二个 2ms子帧第 2、 3个 时隙发送载波 3和载波 1联合编码的 CQI信息;第三个 2ms子帧的第 2、 3个时隙发送载波 2和载波 3联合编码的 CQI信息。如此,每 3个 2ms TTI 周期反复。
当然,本领域技术人员可以理解的是, 单码道发送单元 30发送联合 编码的 CQI信息并不局限于图 1所示的方式, 还可以有其他发送联合编 码的 CQI信息的方式。 比如, 每 3个 2ms子帧第 2、 3个时隙发送两个 载波联合编码的 CQI信息依次可以是(载波 1和载波 2 ) , (载波 2和 载波 3 ) , (载波 3和载波 1 ) 的组合, 也可以是(载波 1和载波 3 ) , (载波 3和载波 1 ) , (载波 2和载波 3 ) 的组合; 也可以是(载波 2 和载波 3 ) , (载波 3和载波 1 ) , (载波 1和载波 2 ) 的组合等等。 本实施例提供的发送反馈控制信息的装置中, 单码道发送单元 30 使用一个 HS-DPCCH码道发送三个载波的反馈控制信息, 可以降低 CM 值, 提高基站覆盖范围。 另外, 单码道发送单元 30在每 3个 2ms TTI 发送的联合编码的 CQI信息中,每个载波对应的 CQI信息发送两次, 可 以使三载波模式下每个载波的 CQI上报周期最小。 这样, 在降低了 CM 值的前提下, 还可以提高对各个载波调度的效率。

双码道发送单元 40, 用于在两个 HS-DPCCH上发送三个载波的反 馈控制信息; 其中, 在 HS-DPCCH1上发送两个载波联合编码的 CQI信 息, 在 HS-DPCCH2 上发送一个载波单独编码的 CQI 信息, 在所述 HS-DPCCH1 或所述 HS-DPCCH2上发送三个载波联合编码的 ACK或 NACK。 双码道发送单元 40在两个 HS-DPCCH上发送三个载波的反馈控制 信息的一种具体方式如下:
HS-DPCCH1 每个 2ms子帧的第 1个时隙发送三个载波联合编码的 ACK/NACK; HS-DPCCH1每个 2ms子帧第 2、 3个时隙发送载波 1和载 波 2联合编码的 CQI信息; HS-DPCCH2每个 2ms子帧第 2、 3个时隙发 送载波 3单独编码的 CQI信息。 如此, 每个 2ms TTI周期反复。
当然,本领域技术人员可以理解的是, HS-DPCCH1联合编码的 CQI 信息也可以是对应载波 2和载波 3的, 或者是对应载波 1和载波 3的。 本领域技术人员可以理解的是, 图 3和图 4所示的发送反馈控制信 息的装置可以是一个终端设备的逻辑单元或一个物理单元。 因此, 本发 明实施例还提供一种终端设备, 如图 5所示, 可以包括如 3和图 4所示 的发送反馈控制信息的装置。 该终端设备还可以包括: 触发单元 50, 用于根据 CQI上报周期的要求, 触发单码道发送单元 30或双码道发送单元 40发送反馈控制信息。 比如, 如果 CQI上报周期 k>=3ms*N—cqi— transmit, 触发单元 50触发单码道发送单元 30发送反馈 控制信息; 如果 CQI上报周期 k=2ms*N—cqi— transmit, 触发单元 50触发 双码道发送单元 40发送反馈控制信息。 其中, 单码道发送单元 30与双 码道发送单元 40发送反馈控制信息的方式可参见图 3和图 4所示的实施 例。 本领域普通技术人员可以理解, 实现上述实施例方法中的全部或部 分流程, 是可以通过计算机程序来指令相关的硬件来完成, 所述的程序 可存储于一计算机可读取存储介质中, 该程序在执行时, 可包括如上述 各方法的实施例的流程。 其中, 所述的存储介质可为磁碟、 光盘、 只读 存储记忆体 ( Read-Only Memory, ROM ) 或随机存储记忆体 ( Random Access Memory, RAM ) 等。 以上仅为本发明的较佳实施例而已, 并非用于限定本发明的保护范围。 凡在本发明的精神和原则之内, 所作的任何修改、 等同替换、 改进等, 均 应包含在本发明的保护范围之内。
