技术领域
本申请涉及通信技术领域，尤其涉及一种数据传输的方法、反馈信息传输方法及相关设备。
背景技术
随着移动数据业务量的不断增长，频段资源越来越紧张，仅使用授权频段资源进行网络部署和业务传输可能已经不能满足移动数据业务量需求，可以考虑在非授权频段资源上部署传输移动数据业务，以提高频段资源利用率和改善用户体验。非授权频段作为辅载波由授权频段的主载波辅助实现移动数据业务的传输。
非授权频段可以为多种无线通信系统如蓝牙、Wi-Fi等共享，多种无线通信系统间通过竞争资源的方式使用共享的非授权频段资源。故不同运行商部署的LTE-U(Unlicensed Long Term Evolution，简称为U-LTE或者LTE-U)间及LTE-U与Wi-Fi等无线通信系统的共存性是研究的一个重点与难点。
为了提供一个灵活、公平的自适应信道接入机制，欧洲电信标准化协会(ETSI)标准要求在非授权的5150兆赫兹(MHz)-5350MHz与5470MHz-5725MHz频段采用先监听后通讯(Listen Before Talk，LBT)技术，LBT过程类似于WiFi的带冲突避免的载波监听多址(Carrier Sense Multiple Access with Collision Avoidance，CSMA/CA)机制，每个设备利用信道之前要进行空闲频道检测(Clear Channel Assessment，CCA)。ETSI标准将非授权频段的设备分类为基于帧的设备(Frame Based Equipment，FBE)与基于负载的设备(Load Based Equipment，LBE)，分别对应两种不同的信道接入机制，如图1a与图1b所示。
FBE信道接入机制中，信道占用时间相对固定，最小1ms、最大10ms。空闲周期至少为信道占用时间的5％。在空闲周期尾部的CCA时间内，设备执行新的CCA检测再次进行信道接入。在FBE信道接入机制中信道占用时间与空闲周期的组合是一个固定值称为帧周期(frame period)。
LBE信道接入机制中，信道传输时间及传输起点都是可变的。在接入信道之前要进行扩展CCA检测，即产生一个随机因子N，直到信道空闲时间达到CCA时间的N倍，才接入信道发起数据传输，且最大的信道占用时间为13ms。
LTE系统支持频分双工模式(Frequency Division Duplexing，FDD)和时分双工模式(Time Division Duplexing，TDD)，两种模式使用不同的帧结构。两种帧结构的共同点是每个无线帧由10个1ms子帧组成。FDD系统使用第一类帧结构如图2a所示，TDD系统使用第二类帧结构，如图2b所示。
从LTE帧结构可看出，以1ms子帧为单位进行信号传输。根据目前3GPP的要求，授权频段上的LTE系统与LTE-U需要在时间上对齐。对LTE-U来说，受LBT竞争接入、射频准备时间等因素影响，LTE-U信号传输的时间起点可能在一个子帧内的任何位置，导致发送的是一个不完整子帧，即时间上少于一个正常子帧长度的物理资源。不完整子帧如果不发信号，在资源竞争激烈情况下该资源必然会被其它节点抢去。
另外，不同地区对非授权频段的连续占用时间是有规定的，如日本规定非授权频段上站点的一次传输的最大时间为4ms。3GPP标准制定在非授权频段上部署LTE系统，需要遵守各地域的规定。因此当非授权频段上一次传输的时间最大为4ms，不完整子帧上不传数据的话，将会严重影响传输效率。
LTE系统中下行控制信令(DCI)通过下行控制信道传输。调度下行子帧n中的物理下行共享信道(Physical Downlink Shared Channel，PDSCH)传输的DCI在下行子帧n中传输。LTE Rel-12支持两种不同的物理下行控制信道：物理下行控制信道(Physical Downlink Control Channel，PDCCH)和增强物理下行控制信道(Enhanced Physical Downlink Control Channel，EPDCCH)。
如图3所示的LTE系统中下行控制信道传输示意图，PDCCH占用每个下行子帧内的前N个正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号传输，基于小区专属参考信号(Cell-specific reference signals，CRS)解调。对于TDD子帧1、6，N可以等于1或2。对于混合载波中的多播广播单频网(MBMS over Single Frequency Network，MBSFN；MBMS，Multimedia Broadcast Multicast Service，多媒体广播多播业务)子帧，N可以等于1或2。对于除TDD子帧和MBSFN子帧之外的普通下行子帧，N可以等于1、2、3或4，其中4只用于系统带宽小于或等于1.4MHz时。EPDCCH占用非PDCCH资源进行传输，且在一个子帧内至少占用一个物理资源块(Physical Resource Block，PRB)对进行传输，EPDCCH基于UE专属参考信号(UE-specific reference signals，通常称为解调参考信号(DeModulation Reference Signal，DMRS))解调。
LTE Rel-12支持两种调度方式：本载波调度和跨载波调度。如图4a所示，本载波调度中，调度载波c上PDSCH/物理上行共享信道(Physical Uplink Shared Channel，PUSCH)传输的DCI在载波c上传输。如图4b所示，跨载波调度中，调度载波c上PDSCH/PUSCH传输的DCI在其他载波上传输。
LTE系统中存在多种参考信号，用于解调的主要有CRS和DMRS两种。CRS映射在 整个下行子帧的全部频段上，在常规循环前缀(Cyclic Prefix，CP)子帧中其结构如图5所示。DMRS只在传输PDSCH或EPDCCH的PRB对上映射，其结构如图6a和图6b所示。
另外，LTE系统中还有信道状态指示参考信号(Channel-State Information Reference Signal，CSI-RS)，用于进行信道状态测量，与CRS类似，CSI-RS也映射在整个下行子帧的全部频段上，具体结构可参考TS36.211中6.10.5节。
对于FDD载波，终端在子帧n上反馈子帧n-4内接收到的PDSCH对应的确认(ACK)/非确认(NACK)信息。对于TDD载波，终端在子帧n上反馈子帧n-k内接收到的PDSCH对应的ACK/NACK信息，其中k的取值与TDD上/下行配置以及子帧n的位置有关，具体如表1所示：

具体实施方式
为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请作进一步地详细描述，显然，所描述的实施例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做出创造性劳动前提下所获得的所有其它实施例，都属于本申请保护的范围。
本申请各实施例中，假设网络设备在非授权频段的系统无线子帧n中接入信道。
本申请第一实施例中，如图7所示，LTE系统中的终端设备在非授权频段上进行数据传输的详细方法流程如下：
步骤701：终端设备根据网络设备发送的信号/信息确定系统无线子帧的起始时刻。
其中，终端设备可根据如下信号/信息中的一种或多种确定系统无线子帧的起始时刻：
当前非授权频段内的主同步/辅同步(PSS/SSS)信号；
主载波上的PSS/SSS信号；
主载波上传输的高层信息；
主载波上传输的下行控制信息。
系统无线子帧包括N个OFDM符号，N为大于1的正整数。
LTE系统中N为14或12。
步骤702：终端设备根据系统无线子帧n+1的起始时刻接收下行控制信息，其中n为系统无线子帧的序号。
其中，根据系统无线子帧的起始时刻确定参考符号，所述参考符号为如下参考符号中的一种或多种：小区专属参考符号(CRS)，解调参考信号(DMRS)，信道状态指示参考信号(CSI-RS)。
步骤703：终端设备根据下行控制信息在系统无线子帧n中确定业务子帧m的起始时刻。
其中，m为业务子帧的序号，业务子帧m的起始时刻与系统无线子帧n的起始时刻不同，且业务子帧的长度与系统无线子帧的长度相同。
终端设备确定业务子帧m的起始时刻为系统无线子帧n中一个OFDM符号的起始时刻。
本申请实施例中，假设业务子帧m由系统无线子帧n中的第A个至第N个OFDM符号，以及第n+1个无线子帧中的第1个至第A-1个OFDM符号组成，其中，A的取值为：大于等于2且小于等于N的正整数。
网络设备在系统无线子帧n中接入信道后可用于数据传输的OFDM符号数量不小于N-A+1，即系统无线子帧n中网络设备可以自第A个OFDM符号开始进行数据传输。
如图8所示，子帧n中的后N-A+1个OFDM符号与子帧n+1中的前A-1个OFDM符号组成业务子帧，一个物理下行共享信道(PDSCH)通过一个业务子帧进行传输，即一个传输块(Transport Block，TB)将通过子帧n中的后N-A+1个OFDM符号与子帧n+1中的前A-1个OFDM符号上的可用资源单元(Resource Element，RE)进行传输，所谓可用RE是指不用于传输物理下行控制信道(PDCCH)、增强物理下行控制信道(EPDCCH)、参考符号(RS)、主/辅同步信号(PSS/SSS)、物理广播信道(PBCH)等非业务信息的RE。
具体实施方式一，网络设备根据接入信道的时间确定A的取值。
具体地，如图9所示，假设N为14，网络设备在时间点t0接入信道，则A可以取5到14之间的任意整数。子帧n中不必要的空闲一方面会造成资源浪费，另一方面会使其他系统接入该频段，因此优选地，A＝6。
具体实施方式二，由系统或协议约定B个可选取值，B为小于等于N-1的正整数，网络设备根据接入信道的时间从B个可选取值中选取一个作为A的取值。
如图9所示，假设N为14，系统或协议预定4个A的取值，分别为2、5、8、11。网络设备在时间点t0接入信道，则A可以取8或11。较优地，A＝8。该方法的优点在于，由于对A的取值做了约束，因此网络设备与终端设备在实现上会有一定的简化。
步骤704：终端设备在业务子帧m中接收业务数据。
假设终端设备在业务子帧m及之后的连续的P-1个业务子帧中接收业务数据，其中，P为正整数。
具体地，终端设备通过下行控制信息调度对应的业务子帧内的业务数据传输，具体实施方式包括但不限于以下三种：
调度方式一，终端设备根据系统无线子帧n+1+p的起始时刻接收下行控制信息，该下行控制信息用于调度业务子帧m+p内的业务数据传输，其中p的取值范围为：大于等于0且小于等于P-1的整数。
调度方式二，终端设备根据系统无线子帧n+1+p的起始时刻接收下行控制信息，该下行控制信息用于调度业务子帧m+p内的业务数据传输，其中p的取值范围为：大于等于0且小于等于P-2的整数；
终端设备根据系统无线子帧n+P-1的起始时刻接收下行控制信息，该下行控制信息用于调度业务子帧m+P-1内的业务数据传输。
调度方式三，终端设备根据系统无线子帧n+1的起始时刻接收下行控制信息，该下行控制信息用于调度业务子帧m内的业务数据传输。
终端设备根据业务子帧m+p的起始时刻接收下行控制信息，该下行控制信息用于调度业务子帧m+p内的业务数据传输，其中p的取值范围为：大于等于1且小于等于P-1的正整数。
本申请第二实施例中，如图10所示，LTE系统中的网络设备在非授权频段上进行数据传输的详细方法流程如下：
步骤1001：网络设备发送信号/信息，该信号/信息用于确定系统无线子帧的起始时刻。
其中，所述信号/信息为如下信号/信息中的一种或多种：
当前非授权频段内的主同步/辅同步PSS/SSS信号；
主载波上的PSS/SSS信号；
主载波上传输的高层信息；
主载波上传输的下行控制信息。
步骤1002：网络设备在系统无线子帧n中确定业务子帧m的起始时刻。
其中，n为系统无线子帧的序号，m为业务子帧的序号，业务子帧m的起始时刻与系统无线子帧n的起始时刻不同，且业务子帧的长度与系统无线子帧的长度相同。
具体地，系统无线子帧n包括N个OFDM符号，N为大于1的正整数；
网络设备确定业务子帧m的起始时刻为系统无线子帧n中一个OFDM符号的起始时刻。
步骤1003：网络设备根据系统无线子帧n+1的起始时刻向终端设备发送下行控制信息， 该下行控制信息用于指示业务子帧m的起始时刻。
步骤1004：网络设备在业务子帧m中发送业务数据。
假设网络设备在业务子帧m及之后的连续的P-1个业务子帧中发送业务数据，其中，P为正整数。
具体地，网络设备通过下行控制信息的调度对应业务子帧中发送业务数据，具体实施方式包括但不限于以下三种：
调度方式一，网络设备根据系统无线子帧n+1+p的起始时刻发送下行控制信息，该下行控制信息用于调度业务子帧m+p内的业务数据传输，其中p的取值范围为大于等于0且小于等于P-1的整数。
调度方式二，网络设备根据系统无线子帧n+1+p的起始时刻发送下行控制信息，该下行控制信息用于调度业务子帧m+p内的业务数据传输，其中p的取值范围为大于等于0且小于等于P-2的整数；
网络设备根据系统无线子帧n+P-1的起始时刻发送下行控制信息，该下行控制信息用于调度业务子帧m+P-1内的业务数据传输。
调度方式三，网络设备根据系统无线子帧n+1的起始时刻发送下行控制信息，该下行控制信息用于调度业务子帧m内的业务数据传输。
网络设备根据业务子帧m+p的起始时刻发送下行控制信息，该下行控制信息用于调度业务子帧m+p内的业务数据传输，其中p的取值范围为：大于等于0且小于等于P-1的整数。
其中，根据系统无线子帧的起始时刻映射参考符号，所述参考符号为如下参考符号中的一种或多种：小区专属参考符号CRS，解调参考信号DMRS，信道状态指示参考信号CSI-RS。
本申请各实施例中，下行控制信息(Downlink Control Information，DCI)的传输具有以下两种实现方式：
第一种实现方式：
DCI可以通过PDCCH或EPDCCH传输，PDCCH或EPDCCH根据系统无线子帧的起始时刻进行映射。
业务子帧m的起始时刻，即系统无线子帧n中A的取值，通过系统无线子帧n+1中的DCI中的特定信息域指示。当使用业务子帧m及之后的连续的P-1个业务子帧进行数据传输时，系统无线子帧n+1+p中的DCI可以包含该特定信息域，也可以不包含该特定信息域，其中p的取值为：大于等于1且小于等于P-1的正整数。
该实现方式的优点在于，DCI的传输可以重用现有的PDCCH或EPDCCH机制。
DCI传输方式a：
对应上述调度方式一。
DCI通过PDCCH传输，具体如下：
系统无线子帧n+1+p上传输的PDCCH用于调度业务子帧m+p上的PDSCH传输，较优地，采用LTE Rel-12系统规定的方式在系统无线子帧n+1+p上传输的PDCCH，其中，p＝0，1，……，P-1，网络设备抢占信道后连续传输P ms。
如图11所示，图中以连续传输4ms为例，实际使用不限于此，PDCCH可以在PDSCH所在的非授权载波上传输，即本载波调度，也可以在其他载波上传输，即跨载波调度。
DCI传输方式b：
对应上述调度方式一。
DCI通过EPDCCH传输，具体如下：
跨载波调度时，系统无线子帧n+1+p上传输的EPDCCH用于调度业务子帧m+p上的PDSCH传输，较优地，采用LTE Rel-12系统规定的方式在系统无线子帧n+1+p上传输的EPDCCH，其中，p＝0，1，……，P-1，网络设备抢占信道后连续传输P ms，如图12所示，图中以连续传输4ms为例，实际使用不限于此。
DCI传输方式c：
DCI通过EPDCCH传输，具体如下：
本载波调度时，系统无线子帧n+1+p上传输的EPDCCH用于调度业务子帧m+p上的PDSCH传输，较优地，采用LTE Rel-12系统规定的方式在系统无线子帧n+1+p上传输的EPDCCH，其中，p＝0，1，……，P-2，网络设备抢占信道后连续传输P ms。子帧n+1到子帧n+P-1中配置传输EPDCCH的第一PRB簇，该第一PRB簇由至少一个PRB组成，当该第一PRB簇由多个PRB组成时，该多个PRB可以在频域上连续或非连续，且第一PRB簇上不用于传输PDSCH，即第一个业务子帧中前N-A+1个符号内，第一PRB簇空闲。
由于EPDCCH在一个系统无线子帧内占用第一PRB簇内的所有OFDM符号传输，最后一个业务子帧m+P-1中用于传输其对应DCI的系统无线子帧n+P是不完整子帧，现有的EPDCCH机制不能直接使用。
对于连续传输的最后一个业务子帧m+P-1的DCI的传输方式包括但不限于以下两种：
DCI传输方式d：
对应于上述调度方式一。
系统无线子帧n+P上传输的EPDCCH用于调度业务子帧m+P-1上的PDSCH传输，网络设备抢占信道后连续传输P ms。在系统无线子帧n+P内，根据A的取值大小，扩展EPDCCH占用的频域资源，即PRB数量，得到第二PRB簇，其中第二PRB簇包含第一PRB簇。在业务子帧m+P-1内第二PRB簇不用于传输PDSCH，如图13所示。
对于常规循环前缀(CP)，系统无线子帧n+P中的DMRS使用TDD特殊子帧所使用 的DMRS结构进行映射。
具体地，当A∈{8、9、10、11}时，系统无线子帧n+P使用特殊子帧配置1/2/6/7对应的DMRS结构；
当A∈{5、6、7、12、13、14}时，系统无线子帧n+P使用特殊子帧配置3/4/8/9对应的DMRS结构；
当A为大于等于2且小于等于4的正整数时，现有DMRS结构无法支持，需要定义新的DMRS结构，其中新的DMRS结构满足前A个OFDM符号中至少有一列DMRS。
对于扩展CP，子帧n+P中的DMRS使用普通下行子帧所使用的DMRS，当A为大于等于2且小于等于6的正整数时，现有DMRS结构无法支持，需要定义新的DMRS结构，其中新的DMRS结构满足前A个OFDM符号中至少有一列DMRS。
DCI传输方式e：
对应于上述调度方式二。
系统无线子帧n+P-1上传输的EPDCCH用于调度业务子帧m+P-1上的PDSCH传输，网络设备抢占信道后连续传输P ms，即系统无线子帧n+P-1同时调度业务子帧m+P-2和业务子帧m+P-1上的PDSCH，如图14所示。业务子帧m+P-1内的第一PRB簇不用于传输PDSCH。
第二种实现方式：
业务子帧m对应的DCI根据系统无线子帧n+1的起始时刻进行传输，业务子帧m之后的连续的P-1个业务子帧中每个业务子帧对应的DCI根据该业务子帧的起始时刻进行传输。
该实现方式适用于本载波调度。
对应于上述调度方式三。
DCI可以通过PDCCH或EPDCCH传输。
业务子帧m对应的PDCCH/EPDCCH根据系统无线子帧n+1的起始时刻进行映射，业务子帧m+p对应的PDCCH/EPDCCH，以该业务子帧自身的起始时刻进行映射，其中p＝1，……，P-1，网络设备抢占信道后连续传输P ms。
业务子帧m的起始时刻，即A的取值，通过系统无线子帧n+1中的DCI中的特定信息域指示。当使用业务子帧m及之后的连续的P-1个业务子帧进行数据传输时，系统业务子帧n+1+p中的DCI可以包含该特定信息域，也可以不包含该特定信息域，其中，p的取值为大于等于1且小于等于P-1的正整数。
该第二种实现方式的优点在于，除业务子帧m外，其他业务子帧的DCI与PDSCH的传输时序关系与LTE Rel-12相同，从而可降低调度复杂度。
如图15所示为使用PDCCH传输DCI的示意图，图中以连续传输4ms为例，实际使用 不限于此。系统无线子帧n+1上传输的PDCCH用于调度业务子帧m上的PDSCH传输，较优地，采用LTE Rel-12系统规定的方式在系统无线子帧n+1上传输的PDCCH，业务子帧m+p上传输的PDCCH用于调度业务子帧m+p上的PDSCH传输，较优地，除PDCCH映射起始时刻不同外，其他机制都沿用LTE Rel-12系统规定的方式在业务子帧m+p上传输的PDCCH，其中，p的取值为大于等于1且小于等于P-1的正整数。
图16所示为EPDCCH传输DCI的示意图，图中以连续传输4ms为例，实际使用不限于此。对于EPDCCH，业务子帧m对应的EPDCCH所占用的PRB簇，记为T，与业务子帧m+1对应的EPDCCH所占用的PRB簇不同。业务子帧m和业务子帧m+1中，PRB簇T不用于传输PDSCH。系统无线子帧n+1上传输的EPDCCH用于调度业务子帧m上的PDSCH传输，较优地，采用LTE Rel-12系统规定的方式在系统无线子帧n+1上传输的EPDCCH，业务子帧m+p上传输的EPDCCH用于调度业务子帧m+p上的PDSCH传输，较优地，除EPDCCH映射起始时刻不同外，其他机制都沿用LTE Rel-12系统规定的方式在业务子帧m+p上传输的EPDCCH，其中，p的取值为大于等于1且小于等于P-1的正整数。
