在无线通信网络中,各个设备需要利用频率资源进行数据传输,频率资源也被称为频谱。频谱可以分为授权频谱和非授权频谱。授权频谱是一些运营商专属的频率资源,非授权频谱是无线通信网络中公用的频率资源。授权频谱上的载波称为授权载波,非授权频谱上的载波称为非授权载波。在无线通信网络中,各个设备可以通过竞争非授权载波传输数据。
为提高信道传输可靠性,HARQ(Hybrid Automatic Repeat Request,混合自动重传请求)作为一种主要的数据重传手段被广泛应用。在LAA-LTE(LicensedAssisted Access Using Long Term Evolution,长期演进的授权辅助接入)系统中,发送设备竞争到非授权载波之后,在非授权载波上传输数据。

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。
应理解,本发明实施例的技术方案可以应用于各种通信系统,例如:全球移动通讯(Global System of Mobile communication,GSM)系统、码分多址(Code Division Multiple Access,CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)系统、通用分组无线业务(General Packet Radio Service,GPRS)、长期演进(Long Term Evolution,LTE)系统、LTE频分双工(Frequency Division Duplex,FDD)系统、LTE时分双工(Time Division Duplex,TDD)、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)或全球互联微波接入(Worldwide Interoperability for Microwave Access,WiMAX)通信系统等。
本发明实施例中,第一设备可以是GSM或CDMA中的基站(英文全称:Base Transceiver Station,英文缩写:BTS),也可以是WCDMA中的基站(NodeB),还可以是LTE中的演进型基站(英文全称:evolved Node B,英文缩写:eNB或e-NodeB),本发明实施例并不限定。
应理解,在本发明实施例中,第二设备包括但不限于用户设备(英文全称:User Equipment,英文简称:UE)、移动台(英文全称:Mobile Station,英文简称:MS)、移动终端(Mobile Terminal)、移动电话(Mobile Telephone)、手机(handset)及便携设备(portable equipment)等,该用户设备可以经无线接入网(英文全称:Radio Access Network,英文简称:RAN)与一个或多个核心网进行通信,例如,用户设备可以是移动电话(或称为“蜂窝”电话)、具有无线通 信功能的计算机等,用户设备还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置。
可以理解的是,当第一设备为基站时,第二设备为用户设备;当第一设备为用户设备时,第二设备为基站;当第一设备为用户设备时,第二设备也可以为用户设备,所述第二设备可以为接收所述第一设备发送的数据的接收设备,本发明不做具体限定。
应理解,本发明实施例提供的数据传输方法可适用于无线通信系统,本发明实施例以应用于LTE(Long Term Evolution,长期演进)/LAA-LTE(LicensedAssisted Access Using Long Term Evolution,长期演进的授权辅助接入)无线通信系统为例对所述方法进行分析说明,不构成对本发明的限定。
在现有LTE系统中,eNB在载波编号为1的非授权载波的第n个子帧发送初传包,UE在第n+4个子帧反馈NACK/ACK消息,eNB需要在接收到NACK反馈消息后,在第n+8个子帧之后(包括第n+8个子帧)重新传输需要重传的数据包,载波编号为1的载波上的每一个重传包都有唯一的HARQ过程号。eNB占用非授权载波信道的时长是有限的,示例性的,eNB占用载波编号为1的非授权载波的时长为10ms(也可以理解为传输10个子帧数据的时长),那么在第3个子帧之后的重传包将在第11个子帧上传输,而此时eNB占用载波编号为1的非授权载波已经到了最大时长,因此,第3个子帧之后的重传包的传输发生中断,UE需等待eNB再次抢占信道后再重传包,从而造成数据延时较大。
实施例一
本发明实施例提供一种数据传输方法,如图1所示,为该数据传输方法的流程示意图,包括:
S101、第一设备在第一载波上向第二设备传输数据。
其中,第一载波为非授权载波。
在LAA-LTE系统中,第一设备通过LBT(1isten before talk,说前先听)原则使用信道资源,其中,LBT是一种CSMA(carrier sense multiple access,载波监听多路访问)技术,即第一设备先监听到非 授权频谱的信道资源空闲,再使用非授权频谱的信道资源来传输数据,非授权频谱上的载波为非授权载波。LBT包括两种工作方式,即LBE(load based equipment,基于负载)的工作方式和FBE(frame based equipment,基于帧)的工作方式。第一设备使用LBE或FBE成功竞争到信道资源后,占用信道发送数据。由于第一设备占用信道存在最大占用时长的限制,因此,第一设备不能始终占用非授权载波传输数据,在占用非授权载波一段时间后,第一设备会释放该非授权载波资源。
S102、第一设备获取第一配置信息。
第一配置信息指示所述重传包在第二载波上传输的顺序或者位置。第一设备获取第一配置信息,具体包括:第一设备确定第一配置信息,并向第二设备发送第一配置信息;或者第一设备接收第二设备发送的第一配置信息;或者第一设备接收第三方设备发送的第一配置信息。
S101和S102没有先后顺序的限制。
S103、第一设备根据第一配置信息在第二载波上向第二设备传输所述数据的重传包。
第一配置信息指示所述重传包在第二载波上传输的顺序或者位置。当第二载波上仅仅传输本载波的数据时,本方案中的第一载波和第二载波为同一个载波,当第二载波上不止传输本载波的数据时,本方案中的第一载波和第二载波为不同的载波。
需要说明的是,第一设备在第一载波上向第二设备传输初传包,并将部分或全部属于第一载波的重传包通过第二载波传输给第二设备。第二载波为授权载波或者非授权载波。
需要补充的是,当第一设备可以在第一载波上向第二设备传输重传包时,第一设备可以选择在第一载波上向第二设备传输重传包,也可以选择在第二载波上向第二设备传输重传包;当第一设备在第一载波上的数据传输中断时,即第一设备不能在第一载波上向第二设备传输重传包时,第一设备在第二载波上向第二设备传输重传包。
在本发明实施例提供的技术方案中,第二载波上可以传输本载 波(即第二载波)的初传包和重传包,以及非授权载波(即第一载波)跨载波传输的重传包。
具体的,第一配置信息指示了在第二载波上传输的所有重传包在第二载波上传输的顺序或者位置,以使得第二设备接收到第一设备在第二载波上传输的重传包之后,可以根据第一配置信息确定每一个重传包是属于哪一个载波的重传包。
需要补充的是,第一配置信息可以根据网络环境周期性进行更新,即第一配置信息是可变的。
具体的,本发明实施例提供了以下三种在第二载波上传输重传包的方法:
(1)第一配置信息为所述重传包所属的第一载波的载波编号的顺序,第一设备根据第一配置信息在第二载波上向第二设备传输所述数据的重传包,具体包括:第一设备根据第一配置信息在第二载波上按照第一载波的载波编号的顺序传输所述重传包。
具体的,载波编号可以为第一设备为各个载波进行的自然编号,也可以为无线通信系统中各个载波的ID号,本发明对此不作限制。
示例性的,假设第一载波为载波编号为1的载波,第一载波上HARQ#C的数据包需要重传,第二载波为载波编号为2的授权载波,第二载波上HARQ#C的数据包也需要重传,且第一配置信息中配置的在第二载波上传输重传包的载波编号的顺序(即第一顺序)为(1,2),即第二载波上的重传包按照其所属的载波的载波编号为(1,2)的顺序依次传输。此处,第二载波上传输的重传包的顺序为:首先传输载波编号为1的载波上的HARQ#C的数据包,紧接着再传输载波编号为2的载波上的HARQ#C的数据包。
进一步的,假设有多个第一载波的重传包需要在第二载波上传输,即载波编号为1的第一载波上HARQ#C的数据包需要重传,载波编号为2的第一载波上HARQ#C的数据包需要重传,载波编号为3的第一载波上HARQ#C的数据包需要重传,载波编号为4的授权载波(即第二载波)上HARQ#C的数据包需要重传,且第一配置信息中配置的在第二载波上传输重传包的载波编号的顺序为 (1,2,3,4),即第二载波上的重传包按照其所属的载波的载波编号为(1,2,3,4)的顺序依次传输。此处,第二载波上的重传包的顺序为首先传输载波编号为1的第一载波上的HARQ#C的数据包,紧接着传输载波编号为2的第一载波上的HARQ#C的数据包,然后再传输载波编号为3的第一载波上的HARQ#C的数据包,最后传输载波编号为4的第一载波上的HARQ#C的数据包。
又示例性的,当各个载波上需要重传的HARQ重传包的过程号不同时,也需要按照第一配置信息中指示的顺序依次传输。假设有多个第一载波的重传包需要在第二载波上传输,即载波编号为1的第一载波上HARQ#A的数据包需要重传,载波编号为2的第一载波上HARQ#B的数据包需要重传,载波编号为3的第一载波上HARQ#C的数据包需要重传,载波编号为4的授权载波(即第二载波)上HARQ#D的数据包需要重传,且第一配置信息中配置的在第二载波上传输重传包的载波编号的顺序为(1,2,3,4),即第二载波上的重传包按照其所属的载波的载波编号为(1,2,3,4)的顺序依次传输。此处,第二载波上的重传包的顺序为:首先传输载波编号为1的第一载波上的HARQ#A的数据包,紧接着传输载波编号为2的第一载波上的HARQ#B的数据包,再传输载波编号为3的第一载波上的HARQ#C的数据包,最后传输载波编号为4的第一载波上的HARQ#D的数据包。
需要说明的是,上述实施例中,第一配置信息中配置的在第二载波上传输重传包的载波编号的顺序为(1,2,3,4),可以理解的是,第一配置信息中配置的重传包的载波编号的顺序还可以为其他顺序,例如(1,3,2,4)、(3,2,1,4)等,在此不一一列举。
又示例性的,在上述实施例中,如果某个载波上没有HARQ重传包需要传输,则在本该传输该载波的HARQ重传包的位置上传输第二载波的初传包;或者,如果某个载波上没有HARQ重传包需要传输,则将排在其后需要传输的重传包依次向前排列,在这种情况下,第二设备需要根据第二设备反馈的NACK消息来确定按照第一顺序接收的重传包是编号为几的载波上的重传包。
(2)第一配置信息为所述重传包在第二载波上传输的第一位置,第一位置包括第二载波中的N个子帧,其中,N为正整数,第一设备根据第一配置信息在第二载波上向第二设备传输所述数据的重传包,具体包括:第一设备根据第一配置信息在第二载波的第一位置传输所述重传包。
需要说明的是,在这种方式中,第一配置信息中指示了第一载波上的重传包在第二载波上传输的第一位置。
重传包在第二载波中重传的位置可以与其在第一载波中的重传位置相同,示例性的,假设第一载波为载波编号为1的载波,第一载波上HARQ#C的数据包将在载波编号为1的载波的子帧1上重传,则第一配置信息中可以指示该重传包在第二载波的子帧1上进行重传。
具体的,假设有多个第一载波的重传包需要在第二载波上传输,即载波编号为1的第一载波上HARQ#C的数据包需要重传,并且其将在载波编号为1的第一载波的子帧1上重传,载波编号为2的第一载波上HARQ#C的数据包需要重传,并且其将在载波编号为2的第一载波的子帧5上重传,载波编号为3的第一载波上HARQ#C的数据包需要重传,并且其将在载波编号为3的第一载波的子帧8上重传,载波编号为4的授权载波(即第二载波)上HARQ#C的数据包需要重传,并且其将在载波编号为4的第二载波的子帧10上重传,则第一配置信息中配置的每一个载波的重传包在第二载波中的位置可以为:载波编号为1的第一载波上的重传包在第二载波的子帧1上重传,载波编号为2的第一载波上的重传包在第二载波的子帧5上重传,载波编号为3的第一载波上的重传包在第二载波的子帧8上重传,载波编号为4的第二载波上的重传包在第二载波的子帧10上重传。
可以理解的是,第一配置信息中指示的第一位置还可以为其他位置,例如,载波编号为1的第一载波上的重传包在第二载波的子帧3和子帧4上重传,载波编号为2的第一载波上的重传包在第二载波的子帧5上重传,载波编号为3的第一载波上的重传包在第二 载波的子帧7上重传,载波编号为4的第二载波上的重传包在第二载波的子帧9、子帧10和子帧11上重传等,即第一配置信息可以为每一个载波的重传包在第二载波上指示任意一个第一位置,且第一位置包括N个子帧,N大于或等于1,本发明对此不作限制。
需要补充的是,若第一配置信息为某一个第一载波在第二载波中指示了用于传输该第一载波的重传包的第一位置,而该第一载波没有需要传输的重传包时,该第一位置可以用来传输本载波(即第二载波)的初传包。
(3)若第一设备还在第二载波上向第二设备传输属于第三载波的重传包,则第一配置信息还包括第三载波的重传包在第二载波上传输的第二位置相对第一位置的偏移量P,第二位置包括所述第二载波中的M个子帧,其中,M为正整数,P为0或者正整数,所述方法还包括:第一设备根据第一配置信息在第二载波的第二位置传输第三载波的重传包。
本发明实施例还提供了另外一种重传包的重传方法,具体的,当第二载波中传输属于多个第一载波的重传包时,第一配置信息中可以仅指示多个第一载波中的一个第一载波的重传包在第二载波中的重传位置(即第一位置),并且在第一配置信息中指示其它第一载波的重传包在第二载波中的传输位置相对第一位置的偏移量。具体的,第一设备在第二载波上向第二设备传输属于第一载波的重传包,同时还在第二载波上向第二设备传输属于其他第一载波(此处即为第三载波)的重传包,则第一设备在第一配置信息指示了第一载波的重传包在第二载波中传输的第一位置,并且指示了第三载波的重传包在第二载波中传输的第二位置相对第一位置的偏移量P。
可以理解的是,如果第三载波存在多个重传数据包需要在第二载波上重传,此时,第一配置信息除了指示第三载波的重传包在第二载波中传输的第二位置相对第一位置的偏移量P之外,还可以指示第二位置中包括的第二载波中的子帧数,例如,第一配置信息指示第二位置包括第二载波中的M个子帧,其中,M为正整数。
示例性的,载波编号为1的第一载波上HARQ#C的数据包需要重传,第一配置信息中指示载波编号为1的第一载波的重传包在第二载波的子帧1(即第一位置)上传输,载波编号为2的第三载波的重传包在第二载波的重传位置与第一位置相差2(此处P为2)个子帧,则载波编号为2的第三载波的重传包在第二载波的重传位置为子帧3,载波编号为3的第三载波的重传包在第二载波的重传位置与第一位置相差6(此处P为6)个子帧,则载波编号为3的第三载波的重传包在第二载波的重传位置为子帧7,载波编号为4的授权载波(即第二载波)的重传包在第二载波的重传位置与第一位置相差8(此处P为8)个子帧,则载波编号为4的授权载波的重传包在第二载波的重传位置为子帧9。
进一步的,若某一个载波没有重传包需要在第二载波中传输,则第一配置信息指示该载波在第二载波中传输其重传包的位置可以传输第二载波的初传包。
需要说明的是,第一设备在非授权载波(假设为第一载波)上的状态为on时,表示第一设备当前正在使用第一载波传输数据,当第一设备在第一载波上的状态为off时,表示第一设备当前无法使用使用第一载波传输数据。因此,当第二设备已知第一设备在第一载波上的on/off状态时,第一设备在第一载波上的重传包根据第一设备和第二设备的约定,可以在第一载波上传输,也可以在第二载波上传输。当第二设备不知道第一设备在第一载波上的on/off状态时,第一设备在第一载波上的重传包在第二载波上传输。
本发明实施例提供的数据传输方法,包括:第一设备在第一载波上向第二设备传输数据;第一设备获取第一配置信息;第一设备根据第一配置信息在第二载波上向第二设备传输所述数据的重传包,第一配置信息指示所述重传包在第二载波上传输的顺序或者位置。当第一设备由于占用第一载波的时间达到最大时长而使重传包的传输产生较大时延时,本发明技术方案能够根据第一设备与第二设备之间预定义的第一配置信息,将第一载波上的重传包在第二载 波上传输,从而解决现有技术中设备需重新抢占非授权载波来传输重传包造成的数据传输延时的问题。
实施例二

S201和S202没有先后顺序的限制。
S203、第二设备根据第一配置信息接收第一设备在第二载波上传输的所述数据的重传包。
第一配置信息指示所述重传包在第二载波上传输的顺序或者位置。第二载波为授权载波或者非授权载波。当第二载波上仅仅传输本载波的数据时,本方案中的第一载波和第二载波为同一个载波,当第二载波上不止传输本载波的数据时,本方案中的第一载波和第二载波为不同的载波
具体的,第一配置信息指示了在第二载波上传输的所有重传包在第二载波上传输的顺序或者位置,以使得第二设备接收到第一设备在第二载波上传输的重传包之后,可以根据第一配置信息确定每一个重传包是属于哪一个载波的重传包。
需要补充的是,第一配置信息可以根据网络环境周期性进行更新,即第一配置信息是可变的。
第一配置信息为所述重传包所属的第一载波的载波编号的顺序,第二设备根据第一配置信息接收第一设备在第二载波上传输的 所述数据的重传包,具体包括:第二设备根据第一配置信息接收第一设备在第二载波上按照第一载波的载波编号的顺序传输的所述重传包。

第三载波为非授权载波。
第二设备接收到第一设备通过第二载波传输的数据之后,根据第一配置信息获取各个载波的重传包,具体的第一配置信息的具体内容如实施例一(3)中的举例说明,在此不再赘述。
需要说明的是,第一设备在非授权载波(假设为第一载波)上的状态为on时,表示第一设备当前正在使用第一载波传输数据,当第一设备在第一载波上的状态为off时,表示第一设备当前无法使用使用第一载波传输数据。因此,当第二设备已知第一设备在第一载波上的on/off状态时,第一设备在第一载波上的重传包根据第一设 备和第二设备的约定,可以在第一载波上传输,也可以在第二载波上传输。当第二设备不知道第一设备在第一载波上的on/off状态时,第一设备在第一载波上的重传包在第二载波上传输。
本发明实施例提供的数据传输方法,包括:第二设备接收第一设备在第一载波上传输的数据;第二设备获取第一配置信息;第二设备根据第一配置信息接收第一设备在第二载波上传输的所述数据的重传包,第一配置信息指示所述重传包在第二载波上传输的顺序或者位置。当第一设备由于占用第一载波的时间达到最大时长而使重传包的传输产生较大时延时,本发明技术方案能够根据第一设备与第二设备之间预定义的第一配置信息,将第一载波上的重传包在第二载波上传输,从而解决现有技术中设备需重新抢占非授权载波来传输重传包造成的数据传输延时的问题。
