Description

控制信息的传输方法、 装置及系统
本申请要求于 2011 年 2 月 23 日提交中国专利局、 申请号为 201110044037.0, 发明名称为 "控制信息的传输方法、 装置及系统" 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, 尤其涉及一种控制信息的传输方法、 装置及系统。
背景技术
混合自动重传请求 (Hybr id Automatic Repeat Request, HARQ) 是一种利用链路级信息进行重传判决的技术。 在 HARQ技术中, 数据 接收方需要向数据发送方反馈应答信息,该应答信息为控制信息中的 一种, 以确认数据是否被正确接收。 在 3GPP LTE ( 3rd Generation Partnership Project Long Term Evolution, 第三代合作伙伴计划 长期演进) 系统中, 该反馈应答信息主要通过物理上行控制信道 ( Physical Uplink Control Channel, PUCCH ) 或物理上行共享信道 ( Physical Uplink Share Channel, PUSCH ) 反馈给基站。
3GPP LTE系统包括频分双工 ( Frequency Division Duplexing, FDD ) 和时分双工 ( Time Division Duplexing, TDD ) 两种系统。 其 中, TDD系统在一个频率信道上发送和接收数据, 但数据的发送和接 收在时间上分开, 即数据的发送和接收使用同一频率载波的不同时 隙。 另外, TDD系统支持不同的上下行配比, 可以根据不同的业务类 型, 半静态调整上下行 S己 t匕 ( Uplink— Downlink Configuration ) , 以满足上下行非对称的业务需求。 并且, 对应不同的上下行配比, 设 置不同的反馈下行传输对应的应答信息的定时关系。 各上下行配比 下, 根据设置的反馈下行传输对应的应答信息的定时关系, 在对应的 上行子帧反馈对应的一个或多个下行子帧的下行传输所对应的应答 信息。
LTE R11版本以前的系统中, 使用哪种上下行配比是半静态配置 的, 会出现配置的上下行配比与瞬时业务类型不匹配, 从而不能有效 利用资源。 为了使实际使用的上下行配比与瞬时业务类型更加匹配, 更有效地利用通信资源, 可在 LTE R 1 1 版本中引入了动态 TDD子帧 应用技术, 即在无线帧内配置一些动态子帧, 该动态子帧既可以作上 行子帧, 也可以作下行子帧。 图 1为一个无线帧内动态 TDD子帧应用 的一种示意图, 其表示每半个无线帧的最后两个子帧为动态子帧。
在实现本发明的过程中, 发明人发现动态 TDD子帧应用场景下, 动态子帧可用于上行传输也可用于下行传输,具体根据瞬时业务类型 而定, 因而形成的上下行配比也是变化的, 且指示动态子帧为上行子 帧还是为下行子帧的信令可能会丟失或被用户设备检测错,从而有可 能导致基站和用户设备对形成的上下行配比的理解不一致, 因而, 若 实时按照形成的上下行配比对应的定时关系去反馈应答信息,会导致 应答信息传输错误,从而不能保证动态 TDD子帧应用场景下数据传输 的安全性。 另外, 动态 TDD子帧应用场景下, 有时形成的配比甚至有 可能不属于现有 LTE TDD系统中的任何一种配比, 因而也无对应的反 馈应答信息的定时关系。 因此, 在动态 TDD子帧的应用场景下如何反 馈应答信息是目前亟待解决的一个问题。

具体实施方式
下面将结合本发明实施例中的附图,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 通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例, 都属于本发明保护的范围。
为了实现在动态 TDD子帧的应用场景下反馈应答信息,本发明实 施例提供了一种控制信息的传输方法, 如图 2所示, 包括: 101、 用户设备确定上行子帧 n对应的子帧集合, 该子帧集合中 包含动态子帧;
本发明所有实施例中的上行子帧 n中的 n为多个无线帧中的子帧 编号,并且, n为大于等于 0的自然数。
举例而言,可以根据预先设定的反馈应答信息的定时关系确定上 行子帧 n 对应的子帧集合^:{"-^"- ,其中 ^,^...^^为正 整数, 该子帧集合中包含动态子帧和固定的下行子帧。 具体地, 可 以根据集合 ^ Α'··^-!}确定上行子帧 η 对应的子帧集合
K':{n-k0,n-k1,---,n-kM_1}, 该子贞集合 K' {n-k0,n- k^-■■ ,n- k,^^}中包含动态子 帧和固定的下行子帧, 该集合 ^ ' 'Ά^}与上行子帧 n对应, 并且 ½,^,.. M— i为正整数。
本发明所有实施例中,动态子帧指无线帧中既可以为上行子帧也 可以为下行子帧的子帧。 动态子帧为上行子帧, 指该动态子帧当作上 行子帧使用, 此时也可称该动态子帧为动态上行子帧; 动态子帧为下 行子帧, 指该动态子帧当作下行子帧使用, 此时也可称该动态子帧为 动态下行子帧。 动态 TDD子帧应用场景下, 基站会配置 N个无线帧中 的每个无线帧的某些子帧为动态子帧, 其余子帧为固定子帧, 其中 N 为大于等于 1的自然数。 固定子帧要么固定为上行子帧, 要么固定为 下行子帧。 动态子帧既可以为上行子帧也可以为下行子帧的子帧, 具 体为上行子帧还是下行子帧需借助其他手段确定,例如动态子帧可以 由基站动态指示其为上行子帧还是下行子帧。
需要说明的是, 本发明所有实施例中, 上行子帧 n对应的子帧集 合中可以包含一个或多个动态子帧, 这些动态子帧可以都为上行子 帧,也可以都为下行子帧,还可以一些为上行子帧,一些为下行子帧。 本发明实施例说上行子帧 n 对应的子帧集合中包含的动态子帧为上 行子帧,指上行子帧 n对应的子帧集合中包含的动态子帧中有一个或 多个动态子帧为上行子帧。
以图 4 所示的一个无线帧的帧结构为例, 一个无线帧的帧长为 10ms, 每一无线帧包括 10 个子帧, 且每一子帧为 1ms; 通常, 在一 个无线帧的 10个子帧按照时间的先后顺序标注为子帧 0 ~ 9,所述 0 ~ 9为一个无线帧中的子帧序号, 例如一个无线帧中的第三个子帧为一 个无线帧中的子帧序号为 2的子帧,一个无线帧中的第八个子帧为一 个无线帧中的子帧序号为 7的子帧。
本发明所有实施例中的子帧编号指子帧在多个无线帧中的编号, 可按如下方式获得:按照时间先后顺序对多个无线帧中的子帧以单调 递增方式从 0开始进行编号,即若上一个无线帧的最后一个子帧的编 号为 ^, 则下一个无线帧的第一个子帧的编号为 ^+1。
多个无线帧中,每个子帧在其所在的那个无线帧中也有一个子帧 序号, 即为该子帧在一个无线帧中的子帧序号。 举例来说, 我们说一 个无线帧中的子帧 2中的 2即为子帧在一个无线帧中的子帧序号。
本发明所有实施例中的上行子帧 n可以为 N个无线帧中每个无线 帧中的第三个子帧或第八个子帧, N为大于等于 1的整数。
1 02、 用户设备根据步骤 1 01得到的子帧集合确定反馈的应答信 息;
举例而言,用户设备可以通过以下方式来根据步骤 1 01得到的子 帧集合确定反馈的应答信息:
确定子帧集合中各子帧对应的应答信息,对各子帧对应的应答信 息进行排序, 得到反馈的应答信息。
具体而言, 若子帧集合中的动态子帧为上行子帧, 则其对应的应 答信息为否认应答信息 NACK ; 或者, 若子帧集合中的动态子帧为上 行子帧, 则其对应的应答信息为非连续传输 DTX。
可以按预定的顺序对各子帧对应的应答信息进行排序,预定的顺 序可以是子帧集合中子帧的排序顺序,即可以按照所述子帧集合中子 帧的排序顺序对各子帧对应的应答信息进行排序,得到反馈的应答信 息。
1 03、 用户设备通过物理上行信道在上行子帧 n向基站发送由步 骤 1 02得到的反馈的应答信息。
举例而言,用户设备可以通过至少以下两种方式通过物理上行信 道在上行子帧 n向基站发送步骤 1 02得到的反馈的应答信息:
方式一、 通过物理上行控制信道在上行子帧 n向基站发送步骤 1 02得到的反馈的应答信息。 方式二、 通过物理上行共享信道在上行子帧 n向基站发送步骤 1 02得到的反馈的应答信息, 具体可如下:
根据步骤 1 01中的集合 ^ {n'^-!}确定反馈的应答信息的比特 数, 具体反馈的应答信息的比特数可以等于 M 或 2M, M 为集合 : {。Α'··Ά— 中元素的个数;
根据得到的反馈的应答信息的比特数确定步骤 1 02 得到的反馈 的应答信息在物理上行共享信道上占用的调制符号个数;
根据得到的调制符号个数确定步骤 1 02 得到的反馈的应答信息 经信道编码后的比特数;
根据得到的反馈的应答信息经信道编码后的比特数,对反馈的应 答信息进行信道编码, 得到信道编码后的应答信息;
通过物理上行共享信道在所述上行子帧 n 向基站发送得到的信 道编码后的应答信息。
本实施例提供的控制信息的传输方法,通过用户设备确定上行子 帧 n对应的子帧集合, 所述子帧集合中包含动态子帧, 根据所述子帧 集合确定反馈的应答信息, 并通过物理上行信道在所述上行子帧 n 向基站发送所述反馈的应答信息,从而将动态子帧对应的应答信息映 射到上行子帧 n上发送,使得反馈应答信息的定时关系不随动态子帧 的变化而变化,避免了由于指示动态子帧为上行子帧还是为下行子帧 的信令丢失或被用户设备检测错误而导致应答信息传输错误的问题。 因此, 实现了在动态 TDD子帧的应用场景下反馈应答信息, 从而降低 了动态 TDD 子帧的应用场景下传输数据丟失的可能性, 保证了动态 TDD子帧的应用场景下数据传输的安全。
与上一实施例相对应的,本发明实施例还提供了一种控制信息的 传输方法, 如图 3所示, 包括:
201、 基站确定上行子帧 n对应的子帧集合, 该子帧集合中包含 动态子帧, 其中, n为上行子帧的子帧编号且 n为大于等于 0的自然 数;
举例而言,基站可以根据预先设定的反馈应答信息的定时关系确 定上行子帧 n对应的子帧集合,该子帧集合中包含动态子帧和固定的 下行子帧。 具体而言, 可以根据集合 ^ Α'··· ^^}确定上行子帧 η 对 应 的 子 帧 集 合 "- ·· '"- , 该 子 帧 集 合 ^^-^,"-^…,"-^^中包含动态子帧和固定的下行子帧, 该动态子帧 可为上行子帧, 该集合 ^ ,^…,^^与上行子帧 η对应。
本步骤中的其他描述可以参看步骤 101 , 此处不再赘述。
202、 基站接收终端在物理上行信道上反馈的应答信息, 并检测 由步骤 201得到的子帧集合中的子帧对应的应答信息。
举例而言 ,基站可以通过至少以下两种方式在上行子帧 η检测步 骤 201得到的子帧集合中的子帧对应的应答信息:
方式一、通过在上行子帧 η在基站预留的应答信息资源上检测步 骤 201得到的子帧集合中的子帧对应的应答信息。
其中,基站预留的应答信息资源可以为基站根据步驟 201得到的 子帧集合预留的用于传输应答信息的物理上行控制信道。 由于步骤 201 中的子帧集合可以是根据集合7^ H^'^-i}确定, 因而也可以说 基站预留的应答信息资源为基站根据集合 : , ,… 预留的用于 传输应答信息的物理上行控制信道。
该方式与步骤 103中的方式一对应。
方式二、 通过在上行子帧 n在物理上行共享信道上检测步骤 201 得到的子帧集合中的子帧对应的应答信息, 具体可以为:
在上行子帧 n根据步骤 201得到的子帧集合确定用户设备反馈的 应答信息的比特数; 由于步骤 201 中的子帧集合可以是根据集合 Κ -^^ ,- Μ^确定, 因 而也可以说在上行子帧 η 根据集合
^{H'''^^}确定用户设备反馈的应答信息的比特数, 具体反馈的应 答信息的比特数可以等于 M或 2M, M为集合 。, 中元素的个 数。
根据得到的用户设备反馈的应答信息的比特数确定用户设备反 馈的应答信息在物理上行共享信道上占用的调制符号个数;
根据得到的调制符号个数检测物理上行共享信道上传输的用户 设备反馈的应答信息, 得到子帧集合中的子帧对应的应答信息。
本实施例提供的控制信息的传输方法, 通过基站确定上行子帧 n 对应的子帧集合, 该子帧集合中包含动态子帧, 接收终端在物理上行 信道上反馈的应答信息,并检测所述子帧集合中的子帧对应的应答信 息, 从而将动态子帧对应的应答信息映射到上行子帧 n上检测, 使得 检测应答信息的定时关系不随动态子帧的变化而变化,避免了由于指 示动态子帧为上行子帧还是为下行子帧的信令丢失或被用户设备检 测错误而导致应答信息传输错误的问题,实现了在动态 TDD子帧应用 场景下反馈应答信息,从而降低了动态 TDD子帧的应用场景下传输数 据丢失的可能性, 保证了动态 TDD 子帧的应用场景下数据传输的安 全。
图 1所示的动态 TDD子帧应用场景中: 一个无线帧中的子帧 0、 子帧 1、 子帧 5和子帧 6 固定为下行子帧, 也可称这 4个子帧为固定 下行子帧; 一个无线帧中的子帧 2和子帧 7固定为上行子帧, 也可称 这 2个子帧为固定上行子帧; 一个无线帧中的子帧 3、 子帧 4、 子帧 8和子帧 9为动态子帧。 下面, 以图 1所示的动态 TDD帧应用场景为 例,即以 N个无线帧中的每个无线帧中的动态子帧按照图 1所示应用 为例, 分别结合在物理上行共享信道 ( Physical Uplink Share Channel, PUSCH ) 和物理上行控制信道 ( Physical Uplink Control Channel, PUCCH )上反馈应答信息这两种情况对上文所述的实施例作 进一步详细描述。
本实施例提供一种在 PUSCH上传输控制信息的方法, 包括: 301、 用户设备确定上行子帧 n对应的子帧集合, 该子帧集合中 包含动态子帧。
用户设备可以根据预先设定的反馈应答信息的定时关系确定上 行子帧 n 对应的子帧集合^{"— U,其中 , … ½_i为正 整数, 该子帧集合中包含动态子帧和固定的下行子帧。 具体地, 可 以根据集合 ^ ' 'Ά-!}确定上行子帧 η 对应的子帧集合
Figure imgf000011_0001
n- kt, i = 0,1,...,Μ -1为多个无线帧中的子帧编号, 该 子帧集合 Κ':{"^。," ,···,"-^-1}中包含动态子帧, 该动态子帧可为上行 子帧, 该集合 {H'^-i}与上行子帧 n 对应。 也可以根据 LTE R8 版本时分双共系统中上下行配比 2 (一个无线帧内下行子帧的个数与 上行子帧的个数比为 4: 1 ) 对应的反馈下行传输对应的应答信息的 定时关系确定上行子帧 n对应的子帧集合,该子帧集合中包含动态子 帧。
举例而言, 本实施例中的集合 i:{fe。,^ ,fcM-i}可以为 {7, 6, 8, 4}或 {7,6,4,8} , 则该步骤中的上行子帧 n 对应的子帧集合可以分别为
{«- 7,n- 6,«- 8,«- 4}或 {«-7,«-6,«-4,«-8} , 子顿„— 4和》— 8为动态子帧。 本实施例中的上行子帧 n可以为 N个无线帧中每个无线帧中的第 三个子帧或第八个子帧, 即为 N 个无线帧中每个无线帧中的子帧 2 或子帧 7, 即为 N个无线帧中每个无线帧中的上行子帧 2或上行子 帧 7, 或称为为 N个无线帧中每个无线帧中的固定上行子帧 2或固定 上行子帧 7, 上行子帧 2和上行子帧 7对应的集合 κ:^。,^···'^-ι}可以 相同也可以不同。
图 5 为反馈应答信息的上行子帧和与其对应的子帧集合中的子 帧的对应关系的一种示意图,以本实施例中的上行子帧 η是 Ν个无线 帧中每个无线帧中的子帧 2 或子帧 7 为例, 若集合 ^ ' '^^}为 ,684}时, 图 5 给出了第二个无线帧中的上行子帧 2 和与其对应的 子帧集合中的子帧的对应关系的示意图, 如图 5所示, 此时第二个无 线帧中的上行子帧 2 ( 其子帧编号为 12 ) 对应的子帧集合 …,"-^^为 {5,6,4,8}, 其中子帧 4和子帧 8为第一个无线帧 中的动态子帧。
该步骤中, 即使动态子帧为上行子帧, 也仍然将其纳入上行子帧 η对应的子帧集合中, 因此, 即使基站和用户设备对动态子帧是上行 子帧还是下行子帧的理解出现不一致时,也能保证 PUSCH上的数据和 其他子帧对应的应答信息的正确接收。
302、 用户设备根据步骤 301得到的子帧集合确定反馈的应答信 息;
举例而言, 用户设备可以通过至少以下两种方式来根据步骤 301 得到的子帧集合确定反馈的应答信息:
方式一、
确定子帧集合中各子帧对应的应答信息,对各子帧对应的应答信 息进行排序, 得到反馈的应答信息。
该方式下, 又可分为如下两步实现:
步骤 302-1-a: 确定子帧集合中各子帧对应的应答信息; 具体可以为: 对于子帧集合中的动态子帧, 若该动态子帧为上行 子帧, 则该动态子帧对应的应答信息为否认应答信息 NACK ; 若该动 态子帧为下行子帧,则该动态子帧对应的应答信息由该子帧下行信息 的检测情况决定。若在该动态子帧没有检测到 PDSCH传输且也没有检 测到指示下行 SPS释放的 PDCCH , 则该动态子帧对应的应答信息为否 认应答信息 NACK , 若在该动态子帧检测到 PDSCH传输但该 PDSCH上 传输的数据至少有一个传输块没有传输对,则该动态子帧对应的应答 信息为否认应答信息 NACK , 若在该动态子帧检测到 PDSCH传输且在 该 P D S C H上传输的数据正确或在该动态子帧检测到指示下行 S P S释放 的 PDCCH , 则该动态子帧对应的应答信息为确认应答信息 ACK。 对于 子帧集合中的下行子帧,其对应的应答信息与动态子帧为下行子帧时 的情况类似, 此处不再赘述。
该步骤中, 确定子帧集合中各子帧对应的应答信息, 也可以直接 确定子帧集合中的各子帧所对应的应答信息比特,其与上段描述的确 定子帧集合中的各子帧所对应的应答信息对应,若子帧对应的应答信 息为 ACK,则该子帧对应的应答信息比特为 1,若子帧对应的应答信息 为 NACK , 则该子帧对应的应答信息比特为 0。
该步骤中, 若应答信息不进行空间捆绑 ( Spa t i a l bund l i ng )且 该载波对应的传输模式允许接收两个码字的传输块( T r a n s m i s s i 0 n b l ock, TB)时, 该步骤中每个子帧对应 2比特的应答信息。 例如若该 子帧对应的应答信息为否认应答信息, 则其内容为 NACK NACK , 该应 答信息对应的应答信息比特为 00 ; 若该子帧对应的应答信息为确认 应答信息, 则其内容为 ACK ACK , 该应答信息对应的应答信息比特为 1 1。
步骤 302-1 -b : 对各子帧对应的应答信息进行排序, 得到反馈的 应答信息。
该步骤中, 可以按预定的顺序对各子帧对应的应答信息进行排 序, 而预定的顺序可以是子帧集合中子帧的排序顺序, 即可以按照所 述子帧集合中子帧的排序顺序对各子帧对应的应答信息进行排序,得 到反馈的应答信息。 例如, 先排子帧集合 ^:{¾^。,¾- ^…'"- J中的子 帧" _ 对应的应答信息, 再排子帧集合中的子帧 "- 对应的应答信 息, 以此类推, 直到排完子帧集合中的子帧 "- 对应的应答信息。 简言之, 当应答信息进行空间捆绑时, 子帧集合中的子帧 "- ' = G,1,'"M-1对应的应答信息比特与反馈的应答信息比特序列中 的。^, = 0,1,'^_1对应。 应答信息通常釆用雷德米勒 (Reed Muller ) 码进行编码, 根据
RM码的特性, 位于应答信息前面的比特具有较好的性能。 该步骤中, 按照所述子帧集合中子帧的排序顺序对各子帧对应的应答信息进行 排序, 使得固定下行子帧对应的应答信息位于反馈的应答信息的前 面, 动态子帧对应的应答信息位于反馈应答信息的后面, 由于动态子 帧可能为上行子帧,此时其对应的应答信息不如其他子帧对应的应答 信息重要, 因而起到了保证重要应答信息性能的作用。
方式二、
若承载应答信息的 PUSCH 传输没有对应的上行分配授权 ( UL grant, 即携带下行控制信息格式 0 或携带下行控制信息格式 4 的 PDCCH信令) , 则按方式一中描述的方法确定反馈的应答信息;
若承载应答信息的 PUSCH传输有对应的上行分配授权,则根据该 上行分配 4受¼中的下行分配指示 ( Downlink Assignment Index, DAI ) 的值确定反馈的应答信息。 举例来说, 非载波聚合场景下, 该步骤具 体为: 先确定反馈的应答信息的比特数0 ΑΩΓ =ν , '为 UL grant 中下行分配指示的值, 表示在集合 ^ ^,…,^^对应的子帧集合 中承载了 UE 的 PDSCH 的下行子帧的个数以及承 载了用于指示释放 UE的下行半持续调度业务 SPS的 PDCCH的下行子 帧 的个数的和; 再按如下方式得到反馈的应答信息比特 ° , n = Q,...,0ACK -l . (,)-i 为 集 合 对 应 的 子 帧 集 合 ^ -^'"- U中的子帧" - 对应的应答信息比特, 并且, 若子 帧集合 ^ — ,"— ^…,"—^^中有某个下行子帧传输下行半持续调度
( Semi-Persistent Scheduling , SPS) 数据, 则该 SPS数据对应的 应答信息为 , 其中, 为子帧 "— 收到的 PDCCH下行控制信 息(DCI )格式中下行分配指示的值, 表示基站在集合^ ^,…,^^对 应的子帧集合 ^ - "- ^-^中调度了 PDSCH的子帧和发送了指 示该 UE的下行 SPS释放的 PDCCH的子帧的累计 ( accumulative) 个 并且 PDCCH 下行控制信息 ( DC I ) 的格式可以为 ( DC I ) 格式 需要说明的是, 在载波聚合场景下, 先按上面的方式一或方式二 得到各载波对应的反馈的应答信息比特序列后,还需再按预定的规则 对各载波对应的反馈的应答信息比特序列进行排序,具体可以按载波 索引从小到大的顺序对各载波所对应的反馈的应答信息比特序列进 行排序, 最终得到该步骤中反馈的应答信息比特序列。
该步骤中, 对于子帧集合中的动态子帧, 若该动态子帧为上行子 帧, 则将该动态子帧对应的应答信息置为否认应答信息 NACK, 根据 雷德密勒 ( Reed Mu l l e r , RM )码的编码特性, 可以使得该动态子帧 对应的应答信息比特不影响其他有效应答信息比特的传输,隐式将其 对应的资源用于有效信息比特的传输,从而提高了有效应答信息比特 的性能,其中有效应答信息比特指子帧集合中基站调度了 PDSCH或发 送了指示下行 SPS 释放的 PDCCH信令的那些子帧对应的应答信息比 特。
303、 用户设备通过物理上行共享信道在上行子帧 n向基站发送 步骤 302得到的反馈的应答信息。
步骤 303-a : 根据步骤 301 中的集合 ^^^'…'^ 确定反馈的应 答信息的比特数。ACK ,具体用户设备可以通过至少以下两种方式实现 该步骤:
方式一、 若应答信息进行空间捆绑, 则反馈的应答信息的比特数 0AOT等于 M; 若应答信息不进行空间捆绑且该载波对应的传输模式允 许接收两个码字的传输块, 则反馈的应答信息的比特数 0ΑΩ:等于 2Μ; Μ为集合 ^ 。^,…,^^中元素的个数。 该方式与步骤 302 中的方式一 对应。
方式二、 若承载应答信息的 PUSCH 传输没有对应的上行分配授 权, 则按方式一确定反馈的应答信息比特数; 若承载应答信息的 PUSCH 传输有对应的上行分配授权, 则反馈的应答信息的比特数 0ACK = !。 该方式与步骤 302中的方式二对应。
步骤 30 3-b : 根据得到的反馈的应答信息的比特数确定步骤 302 得到的反馈的应答信息在物理上行共享信道上占用的调制符号个数; 步骤 303-c: 根据得到的调制符号个数确定步骤 302得到的反馈 的应答信息经信道编码后的比特数;
步骤 303-d: 根据得到的反馈的应答信息经信道编码后的比特 数, 对反馈的应答信息进行信道编码, 得到信道编码后的应答信息; 步骤 303-e: 通过物理上行共享信道在所述上行子帧 n向基站发 送得到的信道编码后的应答信息。
该步骤中, 即使动态子帧为上行子帧, 计算反馈的应答信息比特 数时也仍然按照 M值来计算,使得应答信息在 PUSCH上占用的调制符 号个数不随动态子帧的变化而变化, 从而使得即使基站和 UE对动态 子帧是上行子帧还是下行子帧的理解出现不一致时, 也能保证 PUSCH 上的数据和其他子帧对应的应答信息的正确接收。
304、 基站检测用户发送的应答信息。
该步骤又可分为以下两步:
步骤 304-1: 基站确定上行子帧 n对应的子帧集合, 该子帧集合 中包含动态子帧, 其中, n为上行子帧的子帧编号且 n为大于等于 0 的自然数;
基站可以根据预先设定的反馈应答信, ¾的定时关系确定上行子 帧 n 对应的子帧集合, 该子帧集合中包含动态子帧和固定的下行子 帧。 具体地, 可以根据集合 ^ 。, ^…,^^确定上行子帧 n 对应的子 顿集合 ¾ί—ι} , 该子顿集合 K':{n-k0,n-k1,---,n-kM_1}中包含 动态子帧和固定的下行子帧, 该动态子帧可为上行子帧, 该集合 ^ 。, ^'Ά- 与上行子帧 η对应。
该步骤的具体实现方式可以参看步骤 301 中用户设备确定上行 子帧 η对应的子帧集合的相关描述, 此处不再赘述。
步骤 304-2: 基站接收终端在物理上行信道上反馈的应答信息, 并检测用户设备发送的步骤 304-1 得到的子帧集合中的子帧对应的 应答信息。
步骤 304-2- a: 在上行子帧 n根据步骤 304-1得到的子帧集合确 定用户设备反馈的应答信息的比特数;由于步骤 304-1 中的子帧集合 可以根据集合 ^{H'^-i}确定, 因而也可以说基站在上行子帧 n根 据集合 ^ ,^…,^-^确定用户设备反馈的应答信息的比特数。 具体可 以通过至少以下两种方式实现该步骤:
方式一、 若应答信息进行空间捆绑, 则反馈的应答信息的比特数 等于 Μ; 若应答信息不进行空间捆绑且该载波对应的传输模式允 许接收两个码字的传输块, 则反馈的应答信息的比特数 0Α :等于 2Μ; Μ为集合 ^ 。, ···, ^}中元素的个数。 该方式与步骤 303-a 中的方式 一对应。
方式二、 若承载应答信息的 PUSCH 传输没有对应的上行分配授 权, 则按方式一确定反馈的应答信息比特数; 若承载应答信息的 PUSCH 传输有对应的上行分配授权, 则反馈的应答信息的比特数 0ACK = !。 该方式与步骤 30 3-a中的方式二对应。
步骤 304-2-b : 根据得到的用户设备反馈的应答信息的比特数 确定用户设备反馈的应答信息在物理上行共享信道上占用的调制符 号个数;
步驟 304-2-c : 根据得到的调制符号个数检测物理上行共享信道 上传输的用户设备反馈的应答信息,得到子帧集合中的子帧对应的应 答信息。
本实施例提供的控制信息的传输方法,通过用户设备确定上行子 帧 n对应的子帧集合, 所述子帧集合中包含动态子帧, 根据所述子帧 集合确定反馈的应答信息, 并通过物理上行信道在所述上行子帧 n 向基站发送所述反馈的应答信息; 通过基站确定上行子帧 n对应的子 帧集合, 该子帧集合中包含动态子帧, 接收终端在物理上行信道上反 馈的应答信息, 并检测所述子帧集合中的子帧对应的应答信息, 从而 将动态子帧对应的应答信息映射到上行子帧 n上传输,使得传输应答 信息的定时关系不随动态子帧的变化而变化,避免了由于指示动态子 帧为上行子帧还是为下行子帧的信令丟失或被用户设备检测错误而 导致应答信息传输错误的问题, 因此, 实现了在动态 TDD子帧的应用 场景下反馈应答信息,从而降低了动态 TDD子帧的应用场景下传输数 据丢失的可能性, 保证了动态 TDD 子帧的应用场景下数据传输的安 全。 同时, 本发明实施例中, 即使动态子帧为上行子帧, 计算反馈的 应答信息比特数时也仍然按照 M 值来计算, 使得应答信息在 PUSCH 上占用的调制符号个数不随动态子帧的变化而变化,从而使得即使基 站和 UE对动态子帧是上行子帧还是下行子帧的理解出现不一致时, 也能保证 PUSCH上的数据和应答信息的正确接收。
本实施例提供一种在 PUCCH上传输控制信息的方法, 包括:
401、 用户设备确定上行子帧 n对应的子帧集合, 该子帧集合中 包含动态子帧。
该步骤的具体实现方式可以参看步骤 301 , 此处不再赘述。
该步骤中, 即使动态子帧为上行子帧, 也仍然将其纳入上行子帧 n对应的子帧集合中,使得即使基站和用户设备对动态子帧是上行子 帧还是下行子帧的理解出现不一致时,也能保证其他子帧的应答信息 的正确接收。
402、 用户设备根据步骤 401得到的子帧集合确定反馈的应答信 息;
该方式下, 又可分为如下三步实现:
步骤 402-a : 确定子帧集合中各子帧对应的应答信息;
具体可以为, 若应答信息进行空间捆绑, 对于子帧集合中的动态 子帧, 若该动态子帧为上行子帧, 则该动态子帧对应的应答信息为非 连续传输 DTX或否认应答信息 NACK, 本发明实施例优选为非连续传 输 DTX; 若该动态子帧为下行子帧, 则该动态子帧对应的应答信息由 该子帧下行信息的检测情况决定。 若在该动态子帧没有检测到 PDSCH 传输且也没有检测到指示下行 SPS释放的 PDCCH , 则该动态子帧对应 的应答信息为非连续传输 DTX或否认应答信息 NACK ; 若在该动态子 帧检测到 PDSCH传输但该 PDSCH上传输的数据至少有一个传输块没有 传输对, 则该动态子帧对应的应答信息为否认应答信息 NACK; 若在 该动态子帧检测到 PDSCH传输且在该 PDSCH上传输的数据正确,或者, 在该动态子帧检测到指示下行 SPS释放的 PDCCH , 则该动态子帧对应 的应答信息为确认应答信息 ACK; 对于子帧集合中的下行子帧, 其对 应的应答信息与动态子帧为下行子帧时的情况类似, 此处不再赘述。
该步骤中, 当应答信息不进行空间捆绑, 且该载波对应的传输模 式允许接收两个码字的传输块时, 对于子帧集合中的动态子帧, 若该 动态子帧为上行子帧, 则该动态子帧对应的应答信息为非连续传输 DTX DTX或否认应答信息 NACK NACK , 本发明实施例优选为非连续传 输 DTX DTX; 若该动态子帧为下行子帧, 则该动态子帧对应的应答信 息由该子帧下行信, ¾的检测情况决定。 若在该动态子帧没有检测到 PDSCH传输且也没有检测到指示下行 SPS释放的 PDCCH , 则该动态子 帧对应的应答信息为非连续传输 DTX DTX或否认应答信息 NACK NACK; 若在该动态子帧检测到 PDSCH传输但该 PDSCH上传输的数据至少有一 个传输块没有传输对,则该动态子帧对应的应答信息为否认应答信息 NACK NACK; 若在该动态子帧检测到 PDSCH传输且在该 PDSCH上传输 的数据正确,或者,在该动态子帧检测到指示下行 SPS释放的 PDCCH , 则该动态子帧对应的应答信息为确认应答信息 ACK ACK。 另外, 对于 子帧集合中的下行子帧,其对应的应答信息与动态子帧为下行子帧时 的情况类似, 此处不再赘述。
该步骤中, 即使动态子帧为上行子帧, 确定子帧集合中各子帧对 应的应答信息时, 也将非连续传输 DTX作为其对应的应答信息, 使得 即使基站和用户设备对动态子帧是上行子帧还是下行子帧的理解出 现不一致时, 也能保证其他子帧的应答信息的正确接收。
步骤 402-b: 对各子帧对应的应答信息进行排序, 得到反馈的应 答信息。
该步骤中, 可以按预定的顺序对各子帧对应的应答信息进行排 序, 预定的顺序可以是子帧集合中子帧的排序顺序, 即可以按照所述 子帧集合中子帧的排序顺序对各子帧对应的应答信息进行排序,得到 反馈的应答信息。 例如, 先排子帧集合 ^ : {¾ 。'"-^'' ¾ - ^-1 }中的子帧 。对应的应答信息, 再排子帧集合中的子帧" - 对应的应答信息, 以此类推, 直到排完子帧集合中的子帧 " - 对应的应答信息。 举例 来说,当步驟 402-a中采用应答信息空间捆绑的方式确定子帧集合中 各子帧对应的应答信息时, 根据子帧集合 fe。,re- ^,…," -^- 得到的 反馈的应答信息可用 HARQ-ACK (0) , HARQ-ACK (1) , ··· , HARQ-ACK (M-1) 表示, 其中 HARQ- ACK (O)为子帧" _ 对应的应答信息, HARQ- ACK (l) 为子帧 对应的应答信息, 以此类推, HARQ-ACK (0)为子帧" - 对 应的应答信息。
403、 用户设备通过物理上行控制信道在上行子帧 n向基站发送 步骤 402得到的反馈的应答信息。 该步骤又分为如下几步:
步骤 403- a: 根据步骤 402得到的反馈的应答信息, 确定反馈的 应答信息比特及反馈该应答信息比特的 PUCCH。
举例而言, 假设本实施例中的集合 ^ 。, ι'··Ά-ι}为 {7,6,8,4}, 上行子帧 η为 Ν个无线帧中每个无线帧中个无线帧中的子帧 2或子帧 7, 无线帧的格式如图 2所示, 每个该无线帧中的上行子帧 2和上行 子帧 7所对应的集合^^。' ''''^-1}为{7684}, 而应答信息比特映射表 如图 6所示,此时,步骤 402 中得到的与子帧集合 。,"- ,···,"- 对应 的 反馈 的 应 答信 息 可 用 HARQ- ACK (0), HARQ-ACK (1), HARQ-ACK(2) , HARQ- ACK(3)表示, 根据该得到的反馈的应答信息, 查 找图 6所示的应答信息比特映射表, 查出反馈的应答信息比特 b ( 0 ) 和 b ( 1 ) , 以及反馈该应答信息比特的 PUCCH的 PUCCH信道。 例如, 若与子帧集合 ^ - "- ·',"- J对应的应答信息 HARQ- ACK(O), HARQ-ACK (1) , HARQ-ACK (2) , HARQ - ACK (3)为 ACK, ACK, ACK, ACK , 则查找应答信息比特映射表可知, 反馈的 PUCCH信道为 ^CCH.1, 反馈 的应答信息比特 b ( 0 ) 和 b ( 1 ) 为 1, 1。
该步骤中的" ccH,'表示根据子帧集合中的子帧" 中的 PDCCH 调 度情况, 从基站为子帧《 预留的应答信息资源中选出来的 PUCCH。 具体地, ^rav^M- - xWp+^^+i+^o +AffiocH, 其中 p从集合 {0, 1, 2, 3} 中 选 取 , 以 使 得 NP ≤ nc <Wp+i ,
Figure imgf000020_0001
? 为子帧 中用于传输 PDCCH 的第一个控制信道单元 ( Control Channel Element , CCE ) 的编号,
^PUCCH为高层信令通知的参数。
本发明实施例中, 当需要在上行子帧 "在物理上行控制信道上传 输应答信息时,基站可以根据步骤 401得到的子帧集合预留应答信息 资源, 即预留可用于传输应答信息的物理上行控制信道。 步骤 401 中的子帧集合可以是根据集合 κ ^-^}确定, 因此可以说基站需 根据集合 。, ^…'^-^预留应答信息资源, 具体可以为: 基站先为子 帧集合 ^ ^。'"—^…'"—^^中的每个子帧都在上行子帧 "上预留应答 信息资源, 即预留可用于传输应答信息的物理上行控制信道; 每个子 帧预留多个; 按子帧集合 fe。' '··'κ— ^ - ^中子帧的先后顺序对预 留的应答信息资源进行排序 ,得到基站根据步骤 401得到的子帧集合 在上行子帧 n预留的应答信息资源。 当集合^ ^,^…,^^为卩 ,^或 {7, 6,4, 8} 由步骤 401的描述可知集合^':{¾-^,"- }中的子帧 "_8和子帧 "-4为动态子帧, 当动态子帧作为上行子帧使用时, 基站为 其预留的应答信息资源不被使用,因而可以将其对应的应答信息资源 排在预留资源的最后, 将该部份资源用于其他用途, 从而减少资源浪 费。
该步骤中, 即使动态子帧为上行子帧, 也仍然按照应答信息比特 映射表确定反馈的应答信息比特及反馈该应答信息比特的 PUCCH , 使 得即使基站和用户设备对动态子帧是上行子帧还是下行子帧的理解 出现不一致时, 也能保证其他子帧的应答信息的正确接收。
步骤 403-b : 将步骤 4 03-a得到的反馈的应答信息比特, 通过步 骤 40 3- a得到的反馈该应答信息比特的 PUCCH在上行子帧 n发送给基 站。
404、 基站检测用户发送的应答信息。
该步骤又可分为以下两步:
步骤 404-1 : 基站确定上行子帧 n对应的子帧集合, 该子帧集合 中包含动态子帧;
该步骤的具体实现方式可以参看步骤 401 , 此处不再赘述。 步驟 4 Q4-2 : 基站在上行子帧 n接收终端在物理上行信道上反馈 的应答信息,并检测用户设备发送的与步骤 404-1得到的子帧集合中 的子帧对应的应答信息。
基站接收终端在物理上行信道上反馈的应答信息,并可以在上行 子帧 n在基站预留的应答信息资源上检测步骤 404 - 1得到的子帧集合 中的子帧对应的应答信息,其中基站预留的应答信息资源详细描述见 步骤 403-a, 此处不再赘述。 具体而言, 该步骤可分为以下几步: 步骤 404-2-a : 基站判断可能传输应答信息的物理上行控制信 道。
基站根据调度情况, 判断用户设备发送的应答信息可能在步驟 404-1 中得到的子帧集合中的哪些子帧对应的物理上行控制信道上 传输, 即若基站在步骤 404-1 中得到的子帧集合中的子帧 调度了 PDSCH数据或发送了指示下行 SPS释放的 PDCCH信令, 则判断应答信 息可能在子帧 w - 对应的 4 CCH,''上传输。
步骤 404-2-b: 基站对步骤 404-2-a得到的 1个或多个物理上行 控制信道进行盲检,得到传输应答信息的物理上行控制信道及该信道 上传输的应答信息比特 b ( 0 ) b (l) ;
步骤 404-2-c : 基站根据步骤 404-2-b检测到的应答信息比特 b ( 0 ) b (l)查询图 6 所示的应答信息比特映射表, 得到与步骤 404-1 中得到的子帧集合中的子帧对应的应答信息。
