Description

一种上行控制信息的传输方法及装置
本申请要求在2016年2月2日提交中国专利局、申请号为201610074278.2、申请名称为“一种上行控制信息的传输方法及装置”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
本发明涉及通信领域，特别涉及一种上行控制信息的传输方法及装置。
背景技术
随着移动通信业务需求的发展变化，国际组织对未来移动通信系统都定义了更高的用户面延时性能要求。缩短用户时延性能的主要方法之一是降低传输时间间隔(Transmission Time Interval，TTI)的长度。
参阅图1所示，现有的长期演进(Long Term Evolution，LTE)频分双工(Frequency Division Duplex，FDD)系统使用的帧结构中，上行和下行传输使用不同的载波频率，上行和下行传输均使用相同的帧结构。在每个载波上，一个10ms长度的无线帧包含有10个1ms子帧，每个子帧内由分为两个0.5ms长的时隙。上行和下行数据发送的TTI时长为1ms。
参阅图2所示，现有LTE时分双工(Time Division Duplex，TDD系统使用帧结构中，上行和下行传输使用相同的频率上的不同子帧或不同时隙。每个10ms无线帧由两个5ms半帧构成，每个半帧中包含5个1ms长度的子帧。子帧分为三类：下行子帧、上行子帧和特殊子帧，每个特殊子帧由下行传输时隙(Downlink Pilot Time Slot，DwPTS)、保护间隔(Guard Period，GP)和上行传输时隙(Uplink Pilot Time Slot，UpPTS)三部分构成。。每个半帧中包含至少1个下行子帧和至少1个上行子帧，以及至多1个特殊子帧。
根据3GPP TR36.912附录B.2章节的定义，LTE系统的用户平面(User Plane，简称U平面)时延由基站处理时间、帧对齐时间、TTI时间和终端处理时间四部分构成，其中，帧对齐时间为业务到达至业务能够获得空口子帧传输机会之间的等待时间。
以LTE-FDD下行传输为例，由于FDD系统每个子帧均有下行传输机会，帧对齐时间平均为0.5ms。基站处理时间在下行方向时为1ms，上行方向时为1.5ms；终端处理时间在上行方向时为1ms，下行方向时为1.5ms。因此，在不考虑混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)重传情况下，LTE-FDD下行U平面时延＝基站处理时间1ms+帧对齐时间0.5ms+TTI时间1ms+终端处理时间1.5ms，共4ms。相似的，LTE-FDD 系统不考虑HARQ重传情况下的上行U平面延时也为4ms，具体如图3所示。
对于LTE-TDD系统，基站和终端处理时间以及TTI长度同FDD。帧对齐时间与业务到达的时间和系统所使用的上下行配置有关。
以上下行配置#5为例，基站若在子帧#1中完成发送端处理，则最早到子帧#3才能进行发送，则发射到空口子帧的帧对齐时间平均为1.5ms，其余子帧的帧对齐时间平均为0.5ms，故下行数据的平均对齐处理时间为(1.5+8*0.5)/9＝0.6ms。
上述U平面时延的计算中，基站和终端的处理时间、帧对齐时间都是与TTI长度相关的，如果TTI长度缩短，则U平面的总时延将会缩短。
在现有的LTE帧结构基础上，可以考虑缩短TTI为0.5ms甚至于更小，即一个TTI长度为现有LTE帧结构中的一个时隙所包含的符号数，例如：常规CP时为7个符号，扩展CP时为6个符号；还可以进一步缩短TTI为小于1个时隙的长度，例如：一个或几个符号。
然而，在LTE系统中，现有的信道传输都是以TTI＝1ms来定义的，当业务信道采用非1ms的TTI长度时，数据如何传输目前尚无明确方案。

具体实施方式
下面结合说明书附图对本发明优选的实施方式作出进一步详细说明。
参阅图4所示，本发明实施例中，对上行控制信息进行传输的详细流程如下：
步骤400：终端确定传输上行控制信息的资源，所述资源包括时域占用资源和频域占用资源，其中，所述时域占用资源的时长小于1ms。
步骤410：终端在确定的资源上传输上行控制信息。
具体的，在步骤400中，终端确定的传输上行控制信息的资源中，频域占用资源的大小采用子载波(Sub Carrier，SC)数目表示，或者，采用资源元素(Resource Element，RE)数目表示，或者，采用资源单元(Resource Unit，RU)数目表示，其中，若采用RU表示，则RU为预先定义的在时域上占用X1个符号、在频域上占用X2个SC或RE的资源区域，所述X2个SC或RE为连续或者不连续的，所述X1和X2为预先定义或者配置的，X1、X2均为大0的整数。

本发明实施例中，在执行步骤400时，终端确定传输上行控制信息的资源时，可以采用但不限于以下方法：
方法A：终端根据下行授权信令(DL grant)的通知确定传输上行控制信息的资源，其中，DL grant中所使用的DCI中的指示域指示高层信令预先配置的多个资源集合中的一个。
具体的，DL grant通过携带的DCI中的ACK/NACK资源指示(ARI)域，指示高层信令预先配置的多个资源集合中的一个。
在采用方法A时，高层信令预先配置给终端多个资源集合，网络侧会通过DL grant 通知终端当前哪一个资源集合中指示的资源传输上行控制信息。为了减少系统资源开销，网络侧可以将上述多个资源集合通过高层信令同时配置给多个终端，并进一步通过DL grant指示不同的终端在同一个子帧中使用不同的资源集合。
具体的，资源集合可以采用但不限于以下几种配置方法：
方法A-1：频域占用资源和时域占用资源的大小均可变。
每一个资源集合中均包含频域占用资源的大小和位置、以及时域占用资源的大小，其中，不同资源集合中的频域占用的资源的大小相同或不同，或/和，不同资源集合中的时域占用资源的大小相同或不同。

时域占用资源的大小为终端侧和网络侧协商的固定值，每一个资源集合中均包含频域占用资源的大小和位置，其中，不同资源集合中频域占用资源的大相同或者不同。
进一步地，每一个资源集合中包含时域占用资源的位置，或者，时域占用资源的位置为预先约定的位置。
方法A-4：频域占用资源的大小固定，时域占用资源的大小固定。
时域占用资源的大小为终端侧和网络侧协商的固定值，频域占用资源的大小为终端侧和网络侧协商的固定值，每一个资源集合中均包含频域占用资源的位置。
进一步地，每一个资源集合中包含时域占用资源的位置，或者，时域占用资源的位置为预先约定的位置。
进一步地，DL grant携带的DCI中的ARI域，为DCI中的传输功率控制(TPC，Transmit Power Control)域或者ACK/NACK资源偏移(ARO，ACK/NACK Resource Offset)指示域的重用，或者，为预先定义的一个比特数；
方法B：终端根据上信授权信令UL grant的通知确定传输上行控制信息的资源，其中， UL grant所使用的DCI中的第一指示域用于指示频域占用资源的大小和位置，第二指示域用于至少指示时域占用资源的大小。
进一步地，第二指示域还可以用于指示时域占用资源的位置，或者，若第二指示域不指示，则时域占用资源的位置为预先约定的位置。
方法C：终端根据高层信令的通知确定传输上行控制信息的资源，其中，高层信令配置至少一个资源集合(一个或多个资源集合)，当配置了多个资源集合时，终端从中选取一个资源集合。方法C较适用于周期信道状态信息(Channel State Information，CSI)反馈信息。
具体的，资源集合可以采用但不限于以下几种配置方法：
方法C-1：频域占用资源和时域占用资源的大小均可变。
每一个资源集合中均包含频域占用资源的大小和位置、以及时域占用资源的大小，其中，不同资源集合中的频域占用的资源的大小相同或不同，或/和，不同资源集合中的时域占用资源的大小相同或不同。
进一步地，每一个资源集合中包含时域占用资源的位置，或者，时域占用资源的位置为预先约定的位置。
方法C-2：频域占用资源的大小固定，时域占用资源的大小可变。
频域占用资源的大小为终端侧和网络侧协商的固定值，而每一个资源集合中均包含频域占用资源位置、以及时域占用资源的大小，其中，不同资源集合中的时域占用资源的大小相同或不同；
进一步地，每一个资源集合中包含时域占用资源的位置，或者，时域占用资源的位置为预先约定的位置。

进一步地，每一个资源集合中包含时域占用资源的位置，或者，时域占用资源的位置为预先约定的位置。
在使用方法C时，若高层信令配置了两个资源集合，则终端选取一个资源集合时，可以采用但不限于以下两种方式：
选取方式1：终端根据当前需要反馈的上行控制信息的总比特数，以及每一个资源集合按照特定码率计算得到的能够承载的最大比特数，确定选取的资源集合；或者，当不同资源集合中所包含的时域占用资源的大小不同时，终端根据每一个资源集合中所包含的时域占用资源的大小，确定选取的资源集合。
例如，当上行控制信息的总比特数不超过不同资源集合的可以承载的最大比特数的最小值时，选择所述最小值所对应的资源集合，否则，选择另一个资源集合。
选取方式2：终端根据资源集合中的符号数目，确定选取的资源集合。
例如，终端选择符号数目小于当前上行传输时间段所包含的最大符号数目的资源集合；
如果多个资源集合都满足上述条件或者所有资源集合都不满足上述条件，则进一步使用选取方式1。
进一步地，在上述时域占用资源为预先约定的位置时，终端在不同的情况下可以采用不同的方式确定时域占用资源的起始位置，由于时域占用资源的大小可以是固定的或者由资源集合通知，因此，获知时域占用资源的起始位置后，即可确定时域占用资源的具体位置，即起始位置开始的连续多个符号。
第一种情况下，若上行控制信息为ACK/NACK反馈信息，则确定终端可以采用但不限于以下两种方式：
方式A：终端确定时域占用资源的起始位置为：编号为n+k的时间段中的第一个符号，其中，n为需要进行ACK/NACK反馈的下行数据传输所在的时间段的编号，k为预定的值，n和k均为大于或等于0的整数。
方式B：终端确定时域占用资源的起始位置为：需要进行ACK/NACK反馈的下行数据传输所在的预先划分的用于下行传输的时间段之后的第k个预先划分的用于上行传输的时间段中的第一个符号，k为预定的值。
方式C：终端确定时域占用资源的起始位置为：第一个满足预设的定时关系的符号，所述符号为一个上行发送时间段中的符号。
方式D：终端确定时域占用资源的起始位置为：满足预设的定时关系的一个上行发送时间段中的第一个符号，其中，是否满足所述定时关系由一个下行数据传输的最后一个符号与一个上行发送时间段中的第一个符号的符号间隔确定。
其中，方式C和方式D中提及的定时关系具体表现为处理时延，所述处理时延包括下 行数据解析和处理时间以及产生下行数据所对应的ACK/NACK反馈信息的时间。以一个下行数据的传输结束时刻为基准，其ACK/NACK反馈信息在不早于满足上述处理时延的上行符号中传输。
例如，若处理时延具体表现为a*b，a为预定的常数，a＝3，b为一个下行数据传输所占用的符号数目或者时间长度。
第二种情况下，当上行控制信息为周期CSI反馈信息时，则确定终端可以采用但不限于以下两种方式：
方式E：终端按照预先配置的CSI反馈周期，确定时域占用资源的起始符号位置，其中，所述周期具体表现为Y1个符号，Y1为正整数；或者，
方式F：终端按照预先配置的CSI反馈周期，确定该CSI反馈周期所对应的传输CSI的子帧中的预定的上行符号位置，为时域占用资源的起始符号位置，其中所述CSI反馈周期具体表现为Y2个子帧，Y2为正整数。
例如：频域占用资源的起始位置为：CSI子帧中第一个或最后一个上行传输时间段中的第一个符号。
又例如：当CSI子帧中同时存在ACK/NACK反馈信息时，频域占用资源的起始位置为：该CSI子帧中的传输ACK/NACK反馈信息所在的符号位置。
本发明实施例中，在执行步骤410时，终端可以采用非扩频方式或扩频方式在确定的资源上传输上行控制信息，具体介绍如下：
方法1：终端采用非扩频方式在确定的资源上传输上行控制信息，包括：
首先，终端根据确定的资源中可用于数据传输的RE数目及采用的调制编码方式确定编码比特数，再基于所述编码比特数将上行控制信息进行信道编码和速率匹配，得到相应的调制符号。
可选地，上述信道编码方式可以为A比特循环冗余校验(CRC，Cyclic Redundancy Check)+Turbo编码(turbo coding)or咬尾卷积编码(TBCC，Tail Biting Convolutional Coding)方式，例如：8比特CRC+TBCC方式(即PUCCH format 4/5方式)或24比特CRC+turbo coding。
其次，终端将得到的调制符号按照特定顺序映射到所述资源上进行传输。
例如，可以映射至频域后映射至时域，或者，也可以先映射至时域后映射至频域。
进一步地，若所述资源在PUSCH上，则终端需要将上行控制信息与数据data一起级联传输，进行与数据相同的处理；
方法2：终端采用扩频方式在确定的资源上传输上行控制信息，扩频方式可以采用正 交扩频码(Orthogonal Cover Code，OCC)包括：
首先，终端根据确定的资源中可用于数据传输的RE数目、扩频序列长度及采用的调制编码方式确定编码比特数，再基于所述编码比特数将上行控制信息进行信道编码和速率匹配，得到相应的调制符号。
其次，将获得的每一个调制符号与长度为N的正交序列相乘，得到扩频后的长度为N的调制符号，再将所述长度为N的调制符号，映射到所述资源中的时域占用资源内的一个符号上的一个RE组上进行传输，所述一个RE组中包含N个RE；其中，在所述资源中的频域占用资源上，在上述一个符号内，每N个RE为一组进行频域OCC，其中N为正交序列的长度，N为大于1的整数。
其中，获得的所有调制符号被映射到的上述一个符号上的一RE组上进行传输，该一RE组内的RE在频域上连续分布或离散分布；和/或，获得的不同调制符号被映射到的上述一个符号内的不同RE组内的RE上进行传输，这些RE组内的RE在频域上平行分布或交错分布。
进一步地，当终端确定的时域占用资源中包含多个符号时，终端在每一个符号上按照上述方式进行长度为N的正交序列进行频域扩频；或者，终端在时域上使用长度为B的正交序列进行时域扩频，其中，B为时域占用资源所包含的符号数目中用于数据传输的符号数目；或者，终端在每一个符号上采用长度为N的正交序列进行频域扩频，且终端在时域上使用长度为B的正交序列进行时域扩频，其中，B为时域占用资源所包含的符号数目中用于数据传输的符号数目，B为大于等于1的整数。
另一方面，导频数按照上述相同的方式进行扩频，或者，当导频占用一个符号上的数据传输带宽传输时，可采用循环移位方式进行扩频，其中，循环移位间隔与导频序列长度相关，需满足floor(导频序列长度/循环移位间隔)不小于N或不小于N*M，floor为向下取整。
进一步，终端在传输上行控制信息时还可以携带特定序列，所述特定序列与所述终端的标识(ID)相关，至少用于其他网元(其他终端和/或基站)识别所述终端，以及用于其他网元对所述该终端进行干扰测量，所述其他终端包括本小区和/或邻小区中的终端。
例如：所述特定序列基于ZC序列或m序列或CAZAC序列等序列产生；不排除其他序列产生方式，只要可以支持与UE ID相关，自相关性高，互相关性低的序列都可以采纳。
下面采用一个具体的实例，对OCC扩频方式进行详细说明。具体的OCC扩频方式如下实例，但不限于如下实例：
假设上行控制信息传输所占用的符号(即SC-FDMA符号，以下相同，不再赘述)的 数目为1，则以频域上12个RE(或SC)的区域为例，OCC长度N为2时的频域扩频和映射方式如图5和图6所示。
假设上行控制信息传输所占用的符号数目为3，以频域上12个RE(或SC)的区域为例。
第一种实现方式为：每个符号上都进行长度为N＝2的OCC，频域扩频和映射方式在每个承载数据的符号上都相同，得到如图7和图8所示的方式。
第二种实现方式为：在时域上进行长度为M＝2的OCC，如图9所示；或者，在时域上进行长度为M＝3的OCC，如图10所示。
第三种实现方式为：同时在时域上进行长度为M＝2的OCC，且在频域上进行长度为N＝2的OCC，如图11所示；或者，同时在时域上进行长度为M＝3的OCC，且在频域上进行长度为N＝2的OCC，如图12所示；其中，频域OCC序列与时域OCC序列可以不同。
图5、图7、图9、图10中假设导频还是类似LTE的方式占用一个符号上的所有RE，对于图5，该上行控制信息在当前一个符号传输时，可以借助其前或后一个符号上的导频进行信道估计，此时导频可以类似原LTE系统中的PUCCH设计，进行频域上的循环移位，循环移位间隔和导频长度满足可以区分至少不少于数据符号可以区分的用户数目。导频也可以类似数据的方式进行时域OCC和/或频域OCC。
图6、图8、图10、图12中假设上行传输的导频与数据在一个符号上采用频分方式传输，即占用不同RE传输，导频可以类似原LTE系统中的PUCCH设计，进行频域上的循环移位，循环移位间隔和导频长度满足可以区分至少不少于数据符号可以区分的用户数目，导频也可以类似数据的方式进行时域OCC和/或频域OCC。
上述实施例中，当频域上占用更多RE时，映射方式类似，例如：频域上占用Z个长度为12的RE时，每个长度为12的RE区域可以按照如图5所示的相同方式进行扩频和映射，或者，Z个长度为12的RE联合在一起，按照类似一个长度为12的RE区域的设计方案进行特定间隔的扩频和映射。
另外，对于上述图6、图8、图10、图12所示的导频图样中两个导频符号间隔6个RE，还可以调整间隔为2、3、4、12等其他值，即改变导频时域和或频域密度，具体设计方式上述内容类似，不再赘述。
OCC长度还可以为其他值，例如N＝3、4、5、6等，M＝4、5等，具体设计方式上述内容类似，不再赘述。
下面采用一个具体的实例，对上行控制信息的具体传输过程进行介绍。
具体传输过程的实施例如下：
例如，采用如图5所示导频图样，即导频与上行控制信息单独占用不同的符号，假设上行控制信息传输的资源为时域上1个符号(即SC-FDMA符号，以下相同，将不再赘述)且频域上24个RE，采用四相相移键控(Quadrature Phase Shift Keying，QPSK)调制，则：
在不使用频域OCC时，可用于上行数据传输的RE总数为24个，则可以承载的编码比特数为24*2＝48。假设原始上行控制信息比特数为8比特，则8比特信息加上CRC(例如8比特)校验信息后，经过信道编码和速率匹配得到48比特编码比特(此时码率为1/3)，48比特编码比特经过QPSK调制，得到24个调制符号，分别映射到上述一个符号上的24个RE位置上，具体的，可以从低频到高频逐一映射，也可以从高频到低频逐一映射。
在使用频域OCC时，如图5所示，N＝2，则可用于不同上行数据传输的RE数为12个(虽然总RE有24个，但是两个RE上承载的是相同原比特的扩频版本，实际可以承载的不同的调制符号数仅为12个)，则可以承载的编码比特数为12*2＝24，因此，在相同码率下，可以承载的原始上行控制信息的比特数减少，或者，如果同样承载相同的原始比特数，则编码码率升高。
假设原始上行控制信息比特数为8比特，则8比特信息加上CRC(例如8比特)后，经过信道编码和速率匹配得到24比特编码比特(此时码率为16/24＝2/3)，或者，假设原始上行控制信息比特数为4比特，则4比特信息加上CRC(例如8比特)后，经过信道编码和速率匹配得到24比特编码信息(此时码率为12/24＝1/2)；24比特编码比特经过QPSK调制，得到12个调制符号，每个调制符号经过长度为2的OCC扩频后得到的两个调制符号分别映射到上述一个符号上的2个RE位置上，按照特定顺序逐一扩频和映射，具体的，可以从低频到高频逐一映射，也可以从高频到低频逐一映射。
当改变占用符号数目和/或频域占用资源大小(RE数目)时，上述编码比特数将随之发生变化，如果码率相对不变，则可以承载的原始上行控制信息比特数也随之发生变化。
又例如，采用如图6所示导频图样，即导频与数据在同一个符号上频分传输，假设上行控制信息传输的资源为时域上1个符号且频域上24个RE，采用QPSK调制，则：
在不使用频域OCC时，可用于上行数据传输的RE总数为24-4＝20个，则可以承载的编码比特数为20*2＝40。假设原始上行控制信息比特数为8比特，则8比特信息加上CRC(例如8比特)校验信息后，经过信道编码和速率匹配得到40比特编码比特(此时码率为16/40＝2/5)，40比特编码比特经过QPSK调制，得到20个调制符号，分别映射到上述一个符号上的20个RE位置上，具体的，可以从低频到高频逐一映射，也可以从高频到低频逐一映射。
在使用频域OCC时，如图6所示，N＝2，则可用于不同上行数据传输的RE数为(24-4) /N＝10个(虽然可用与数据的总RE有20个，但是两个RE上承载的是相同原比特的扩频版本，实际可以承载的不同的调制符号数仅为10个)，则可以承载的编码比特数为10*2＝20，因此，在相同码率下，可以承载的原始上行控制信息的比特数减少，或者，如果同样承载相同的原始比特数，则编码码率升高。
假设原始上行控制信息比特数为8比特，则8比特信息加上CRC(例如8比特)校验信息后，经过信道编码和速率匹配得到20比特编码比特(此时码率为16/20＝4/5)，或者，假设原始上行控制信息比特数为4比特，则4比特信息加上CRC(例如8比特)后，经过信道编码和速率匹配得到20比特编码信息(此时码率为12/20＝3/5)；20比特编码比特经过QPSK调制，得到10个调制符号，每个调制符号经过长度为2的OCC扩频后得到的两个调制符号分别映射到上述一个符号上的2个RE位置上，按照特定顺序逐一扩频和映射，具体的，可以从低频到高频逐一映射，也可以从高频到低频逐一映射。
当改变占用符号数和/或频域占用资源大小(RE数目)时，上述编码比特数将随之发生变化，如果码率相对不变，则可以承载更多的原始上行控制信息比特数。
