Description

授权辅助接入系统中用于传输上行数据的方法和装置 技术领域
本发明涉及通信领域,并且更具体地,涉及授权辅助接入系统中用于传输上行数据的方法和装置。
背景技术
在授权辅助接入(Licensed-Assisted Access,LAA)系统中,LAA节点通过说前先听(Listen Before Talk,LBT)原则使用信道资源,其中,LBT是一种载波侦听多路访问(Carrier Sense Multiple Access,CSMA)技术,即在侦听到非授权频谱的信道资源空闲之后,使用所述非授权频谱的信道资源来传输数据。LBT包括基于负载(Load Based Equipment,LBE)的方式和基于帧(Frame Based Equipment,FBE)的方式,其中,LBE方式是指基于当前是否需要发送数据以及待发送的数据量,来确定是否竞争信道以及占用信道的时长,FBE方式是指按照帧结构抢占信道并且占用信道的时长固定。
LAA节点(例如用户设备或基站)在采用LBE或FBE方式成功抢占信道之后,占用该信道发送数据,其中,LAA节点每次占用信道的时间应不超过最大占用时长,例如,对于FBE方式,该最大占用时长为10ms,而对于LBE方式,该最大占用时长为13ms。因此,LAA节点在占用信道一段时间之后,需要释放信道,并且在需要使用信道时再次抢占信道资源。
在现有的LTE系统中,用户设备和基站之间的上行传输采用同步混合自动重传请求(Hybrid Automatic Repeat Request,HARQ)模式。如图1所示,在该同步HARQ模式中,用户设备(User Equipment,UE)在子帧n首次传输数据包,基站(例如,evolved NodeB,eNB)在子帧n+4向该UE反馈确认(Acknowledgement,ACK)或者否认(Non-acknowledgement,NACK)信息,如果UE反馈否认信息(NACK),则该UE需要在子帧n+8重传该数据包。然而,由于在非授权载波上最大占用时长的限制,UE可能只抢占到子帧n-3到子帧n+7的资源,因此,如图1所示,UE无法在本次占用信道期间重传该数据包,现有的HARQ重传机制无法适用于LAA系统,使得LAA系统的可行性和系统性能较差。

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,所描述的实施例是本发明的一部分实施例,而不是全部实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例,都应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采用LAA机制的各种通信系统,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、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)、以及未来的5G通信系统等。
还应理解,在本发明实施例中,用户设备可以经无线接入网(Radio Access Network,简称为“RAN”)与一个或多个核心网进行通信,该终端设备可称为接入终端、终端设备、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。用户设备可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol,SIP)电话、无线本地环路(Wireless Local Loop,WLL)站、个人数字处理(Personal Digital Assistant,PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备以及未来5G网络中的用户设备。
还应理解,在本发明实施例中,网络设备可用于与用户设备进行通信,该网络设备可以是GSM系统或CDMA中的基站(Base Transceiver Station,BTS),也可以是WCDMA系统中的基站(NodeB,NB),还可以是LTE系统中的演进型基站(Evolutional Node B,eNB或eNodeB),或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络中的基站设备等。
还应理解,在本发明实施例可以应用于授权载波辅助的接入系统,即UE在授权载波的协助下进行非授权载波的接入,该系统不支持非授权载波的单独接入。在该系统中,非授权载波的接入可以采用LBT机制,并且非授权载波的每次接入时长也都会受到限制。在本发明实施例中,将该系统称为授权辅助接入(Licensed-Assisted Access,LAA)系统,但该系统也可以具有其它名称,本发明实施例对此不做限定。
蜂窝网中的网络设备(例如基站或基站控制器,等等)和用户设备可以采用授权载波或非授权载波进行通信。网络设备或用户设备在使用非授权载波进行数据传输之前,可以与无线局域网(Wireless Local Area Network,WLAN)中的节点以及与采用LAA机制的蜂窝网中的其他LAA节点竞争该非授权载波上的资源,并且在竞争到资源后采用竞争到的资源进行数据传 输,其中,该用户设备或网络设备可以基于LBE方式或FBE方式竞争信道,本发明实施例对此不做限定。
图2是本发明实施例提供的LAA系统中用于传输上行数据的方法100的示意性流程图。该方法100可以由用户设备执行。
S110,接收网络设备发送的模式配置指示信息,该模式配置指示信息用于指示为UE在非授权载波上的上行传输配置同步HARQ模式和异步HARQ模式。
该网络设备为UE配置适用于非授权载波上的上行传输的同步HARQ模式和异步HARQ模式,这样,该UE在进行该非授权载波上的具体上行传输时,可以从该配置的同步HARQ模式和异步HARQ模式中确定采用的HARQ模式。可选地,该UE可以在该非授权载波上的一个或多个上行传输中可以采用同步HARQ模式,而在该非授权载波上的其它上行传输中可以采用异步HARQ模式,但本发明实施例不限于此。
作为一个可选实施例,该模式配置指示信息可以用于指示为该UE在一个或多个具体的非授权载波上的上行传输配置同步HARQ模式和异步HARQ模式,此时,该UE在该一个或多个非授权载波上进行上行传输时,可以从该可选的同步HARQ模式和异步HARQ模式中确定本次上行传输采用的HARQ模式;而该UE在除该一个或多个非授权载波之外的其它非授权载波上进行上行传输时,可以只有一种可选的HARQ模式,即同步HARQ模式或异步HARQ模式。作为另一个可选实施例,该模式配置指示信息可以用于指示为该UE在所有非授权载波上的上行传输配置同步HARQ模式和异步HARQ模式,此时,该UE可以在所有非授权载波上进行上行传输时,从可选的该同步HARQ模式和异步HARQ模式中,确定本次上行传输采用的HARQ模式,但本发明实施例不限于此。
S120,根据该模式配置指示信息,在该非授权载波上采用该同步HARQ模式或该异步HARQ模式进行上行传输。
该UE在接收到该模式配置指示信息之后,可以确定在该非授权载波上可以采用的HARQ模式为同步HARQ模式和异步HARQ模式,并且根据每次上行传输的具体情况,确定本次上行传输采用同步HARQ模式还是采用异步HARQ模式。
因此,根据本发明实施例的LAA系统中用于传输上行数据的方法,通 过为用户设备在非授权载波上的上行传输配置同步HARQ模式和异步HARQ模式,以使得用户设备可以在该非授权载波上进行具体上行传输时,确定采用同步HARQ模式或异步HARQ模式,能够避免由于该UE在非授权载波上竞争到的时间资源有限而造成该UE无法进行重传,从而增强该UE在非授权载波上进行上行传输的灵活性,并且使得网络设备能够对接收到的该UE多次发送的上行数据进行合并处理,提高数据传输性能和系统整体性能。
在本发明实施例中,在同步HARQ模式中,某一子帧与其对应的重传子帧之间的间隔可以固定,例如,数据传输所占子帧的子帧号与反馈子帧的子帧号以及反馈子帧的子帧号与重传子帧的子帧号之间的间隔均为4,接收端不需要被告知某一数据重传对应的HARQ进程号;而在异步HARQ模式中,可以在上一次传输之后的任何可用时间上进行数据重传,接收端需要被告知某一数据传输对应的具体HARQ进程号,但本发明实施例不限于此。
作为一个可选实施例,该模式配置指示信息还用于指示该UE在该同步HARQ模式和该异步HARQ模式之间的模式切换。
此时,该模式配置指示信息还用于指示该UE可以在该同步HARQ模式和异步HARQ模式之间进行切换。可选地,该模式配置指示信息还可以用于指示该UE的缺省HARQ模式配置,例如,该模式配置指示信息可以用于指示该UE在缺省条件下采用同步HARQ模式在该非授权载波上进行上行传输。可选地,该模式配置指示信息还可以进一步指示该同步HARQ模式和该异步HARQ模式之间进行切换的切换触发条件,例如,该模式配置指示信息可以用于指示该UE在确定根据该同步HARQ模式无法在该非授权载波上进行上行数据的重传时(例如未竞争到采用该同步HARQ模式在该非授权载波进行上行数据重传所需的资源),从该同步HARQ模式切换到异步HARQ模式,但本发明实施例不限于此。
在本发明实施例中,该网络设备可以通过多种方式向该UE发送该模式配置指示信息。例如,将该模式配置指示信息携带在下行控制信息(Downlink Control Information,DCI)、无线资源控制(Radio Resource Control,RRC)信令、系统消息(例如,系统信息块(System Information Block,SIB))或其它消息发送,本发明实施例对此不做限定。
作为一个可选实施例,S110,接收网络设备发送的模式配置指示信息, 包括:
接收该网络设备发送的系统消息,该系统消息中携带该模式配置指示信息;或
接收该网络设备发送的RRC信令,该RRC信令中携带该模式配置指示信息;或
接收该网络设备发送的DCI,该DCI中携带该模式配置指示信息。
该网络设备可以通过单播方式向该UE发送该模式配置指示信息。可选地,如果该网络设备为支持LAA的多个UE在非授权载波上的上行传输均配置该同步HARQ模式和异步HARQ模式,则该网络设备可以通过广播方式或组播方式发送该模式配置指示信息,本发明实施例对此不做限定。
在S120中,该UE在采用该非授权载波进行某次上行传输时,可以采用多种方式从该同步HARQ模式和该异步HARQ模式中确定采用的HARQ模式。作为一个可选实施例,如图3所示,S120,在该非授权载波上采用该同步HARQ模式或该异步HARQ模式进行上行传输,包括:
S121,在确定未竞争到所需资源时,采用该异步HARQ模式重传上行数据,其中,该所需资源为根据该同步HARQ模式重传该上行数据时所需的该非授权载波上的资源。
该所需资源为该非授权载波上的资源,并且该所需资源位于该上行数据在该同步HARQ模式中对应的第一重传子帧内,其中,该上行数据在同步HARQ模式中对应的第一重传子帧可以具体为传输该上行数据所占用的子帧在该同步HARQ模式中对应的第一重传子帧。可选地,该所需资源可以包括该第一重传子帧中的所有符号资源,或者仅包括该第一重传子帧中的部分符号资源,本发明实施例不限于此。
该UE在确定未竞争到采用该同步HARQ模式在该非授权载波上重传上行数据所需的资源时,可以确定采用异步HAQ模式在该非授权载波上重传该上行数据。例如,该UE在第一子帧上向网络设备传输上行数据(采用该非授权载波或其它载波),并且该UE在与该第一子帧对应的反馈子帧上接收到该网络设备发送的用于指示未成功接收该上行数据的反馈信息(例如NACK),则该UE可以根据该同步HARQ模式确定与该第一子帧对应的第一重传子帧,并且确定在该第一重传子帧上重传该上行数据。进一步地,该UE可以确定是否竞争到该非授权载波上的所需资源,其中,该所需资源位 于该第一重传子帧内。如果该UE确定竞争到该非授权载波上的所需资源,则该UE可以采用竞争到的该非授权载波上的位于该第一重传子帧内的资源重传该上行数据;如果该UE确定未竞争到该非授权载波上的所需资源,则该UE可以确定从该同步HARQ模式切换到异步HARQ模式,并采用该异步HARQ模式在该非授权载波上进行上行数据的重传,但本发明实施例不限于此。
在本发明实施例中,该UE可以通过多种方式确定未竞争到该非授权载波上的所需资源。作为一个可选实施例,可以由该UE与其它节点竞争非授权载波上的所需资源,具体地,该UE可以侦听该非授权载波的信道,并且根据侦听结果确定是否竞争到该非授权载波上的所需资源。此时,如果该UE根据侦听结果确定竞争到该非授权载波上的所需资源,则该UE可以采用竞争到的该非授权载波上的资源重传该上行数据。作为另一个可选实施例,可以由该网络设备与其它节点竞争该非授权载波上的所需资源,例如,该网络设备侦听该非授权载波的信道,并根据侦听结果确定是否竞争到该非授权载波上的所需资源。此时,如果该网络设备竞争到该非授权载波上的所需资源,则可以调度该UE采用该网络设备竞争到的该非授权载波上的资源进行上行数据的重传;而如果该网络设备未竞争到该非授权载波上的所需资源,则该网络设备可以向该UE发送竞争失败指示信息,相应地,该UE可以根据该竞争失败指示信息确定未竞争到该非授权载波上的所需资源,但本发明实施例不限于此。
作为一个可选实施例,该确定未竞争到所需资源,包括:
接收该网络设备发送的第三指示信息,该第三指示信息用于指示该网络设备未竞争到该所需资源;
根据该第三指示信息,确定未竞争到该所需资源。
该第三指示信息可以在授权载波上发送,或者可以在该网络设备竞争到的该非授权载波的资源上发送,或者也可以在该网络设备竞争到的不同于该非授权载波的其它非授权载波的资源上发送。此外,该第三指示信息可以携带在DCI、RRC信令或其它消息中发送,本发明实施例不限于此。
应理解,在本发明实施例中,未竞争到非授权载波上的所需资源可以指该UE或该网络设备对该非授权载波上的所需资源的竞争结果为失败,具体可以指未竞争到该非授权载波上的位于该第一重传子帧内的所有资源;或 者,可以指竞争到该非授权载波上的位于该第一重传子帧内的一部分资源,并且未竞争到该非授权载波上的位于该第一重传子帧内的另一部分资源,其中,该竞争到的位于该第一重传子帧内的资源少于重传该上行数据所需的资源,但本发明实施例不限于此。
该UE在确定未竞争到该非授权载波上的所需资源时,可以通过多种方式确定从同步HARQ模式切换到异步HARQ模式,并采用该异步HARQ模式进行上行数据的重传。可选地,该UE可以在确定未竞争到该非授权载波上的所需资源时,根据预设模式切换触发条件或其它配置,确定需要从同步HARQ模式切换到异步HARQ模式。此时,该UE可以进一步将该UE在重传该上行数据时采用的HARQ模式通知该网络设备,以使得该网络设备根据该UE通知的HARQ模式接收该UE重传的该上行数据。相应地,在S121之前,该方法100还包括:
在确定未竞争到所需资源时,确定采用该异步HARQ模式重传该上行数据;
向该网络设备发送第一指示信息,该第一指示信息用于指示该用户设备采用该异步HARQ模式重传该上行数据。
该第一指示信息可以用于指示该UE采用该异步HARQ模式进行数据传输。这样,该网络设备在接收到该第一指示信息之后,可以根据该第一指示信息指示的该异步HARQ模式,确定与该上行数据对应的第二重传子帧,并且在该第二重传子帧上接收该用户设备在该非授权载波上重传的该上行数据,但本发明实施例不限于此。
可选地,该第一指示信息可以携带在上行控制信息(Uplink Control Information,UCI)中发送。此外,该UE可以采用授权载波向该网络设备发送该第一指示信息,或者采用竞争到的该非授权载波上的资源向该网络设备发送该第一指示信息,本发明实施例对此不做限定。此外,该UE可以在该第一指示信息中显式或隐式地指示采用该异步HARQ模式进行该上行数据的重传。可选地,该第一指示信息可以包括该异步HARQ模式的信息,并且如果该UE具有多个待重传的上行数据,则该第一指示信息还可以进一步包括与该上行数据对应的HARQ进程的信息,例如HARQ进程的编号,但本发明实施例不限于此。可选地,作为另一实施例,该第一指示信息也可以显式地指示采用该异步HARQ模式进行该上行数据的重传,例如,该第 一指示信息占用1个比特位,并且当该比特位的值置为1时表示该UE采用的HARQ模式保持不变或者指示该UE采用同步HARQ模式,该比特位的值置为0时表示该UE采用异步HARQ模式或者表示该UE改变采用的HARQ模式或该UE采用的HARQ模式由同步HARQ模式切换至异步HARQ模式;或者反之,但本发明实施例不限于此。
作为另一个可选实施例,该网络设备在确定未竞争到该非授权载波上的所需资源时,可以确定该UE需要采用异步HARQ模式进行该上行数据的重传,并且将该决定通知该UE,相应地,该UE可以根据该网络设备发送的指示信息确定采用该异步HARQ模式进行该上行数据的重传。此时,可以由该网络设备竞争该非授权载波上的资源,或者由该UE竞争该非授权载波上的资源并且该UE向该网络设备上报该UE未竞争到该非授权载波上的所需资源,但本发明实施例不限于此。相应地,在S121之前,该方法100还包括:
接收该网络设备在确定未竞争到所需资源时发送的第二指示信息,该第二指示信息用于指示该用户设备采用该异步HARQ模式重传该上行数据;
根据该第二指示信息,确定采用该异步HARQ模式重传该上行数据。
该第二指示信息可以在授权载波上发送,或者可以在该网络设备竞争到的该非授权载波的资源上发送,或者也可以在该网络设备竞争到的不同于该非授权载波的其它非授权载波的资源上发送。此外,该第二指示信息可以携带在DCI或RRC信令或其它消息中发送,本发明实施例对此不做限定。
该第二指示信息可以显式或隐式地指示该UE采用异步HARQ模式进行该上行数据的重传,其中,该第二指示信息携带的信息可以参照上文对该第一指示信息的描述,为了简洁,这里不再赘述。
作为一个可选实施例,该第二指示信息携带在下行控制信息中。此时,该第二指示信息包括下列字段中的至少一种:HARQ模式字段和HARQ映射字段,其中,该HARQ模式字段用于指示采用同步HARQ模式或异步HARQ模式,该HARQ映射字段用于指示该上行数据对应的HARQ进程号。
表1示出了该第二指示信息为DCI时的一个示例,其中,载波指示区域(Carrier Indicator Field,CIF)字段占用3个比特,用于指示该DCI调度的载波,HARQ编号字段对于频分双工(Frequency Division Duplex,FDD)系统占用3个比特,对于时分双工(Time Division Duplex,TDD)系统占用4 个比特,用于指示HARQ进程的编号,新数据指示(New Data Indicator,NDI)字段占用1个比特,用于表示传输类型,其中,该比特位的值为0时表示新传输,该比特位的值为1时表示重传,调制编码机制(Modulation and Coding Scheme,MCS)字段占用5个比特,用于指示传输时采用的MCS,HARQ模式字段占用1个比特位,用于指示同步HARQ模式或异步HARQ模式。可选地,该DCI还可以具体其它格式,本发明实施例不限于此。

在本发明实施例中,该UE可以只要确定未竞争到该非授权载波上的所需资源,就采用异步HARQ模式进行该上行数据的重传。作为另一个可选实施例,S121,在确定未竞争到所需资源时,采用该异步HARQ模式重传该上行数据,包括:
在确定该所需资源中的未竞争到的部分在该所需资源中所占的比例超过阈值时,采用该异步HARQ模式重传该上行数据;
相应地,该方法100还包括:
在确定该所需资源中的未竞争到的部分在该所需资源中所占的比例低于该阈值时,采用该同步HARQ模式重传该上行数据。
该阈值可以由该网络设备配置,或者可以预定义,本发明实施例不限于此。此时,该UE可以确定该非授权载波上的所需资源中的未竞争到的部分在该所需资源中所占的比例,并且只有在确定未竞争到的部分在该所需资源中所占的比例超过一定阈值时,例如在图4所示的场景中,该UE确定未竞争到该非授权载波上的位于该第一重传子帧内的任何资源,才采用异步HARQ模式进行上行数据的重传;否则,例如,如图5所示,该UE确定竞争到该非授权载波上的所需资源的很大一部分,该UE可以采用同步HARQ模式进行该上行数据的重传。
作为一个可选实施例,该在确定该所需资源中的未竞争到的部分在该所需资源中所占的比例低于该阈值时,采用该同步HARQ模式重传该上行数据,包括:
在确定该所需资源中的未竞争到的部分在该所需资源中所占的比例低 于该阈值时,根据该所需资源中的未竞争到的部分,对该上行数据进行打孔处理。
该UE可以对该上行数据中与该未竞争到的部分相对应的部分进行打孔处理,并且采用该第一重传子帧中的竞争到的资源重传该经过打孔处理的该上行数据。此时,该网络设备在接收到该经过打孔处理的该上行数据之后,仍然可以将接收到的该UE之前传输的该上行数据与接收到的该UE重传的经过打孔处理的该上行数据进行合并处理,但本发明实施例不限于此。
因此,根据本发明实施例的LAA系统中用于传输上行数据的方法,通过为用户设备在非授权载波上的上行传输配置同步HARQ模式和异步HARQ模式,以使得用户设备可以在该非授权载波上进行具体上行传输时,确定采用同步HARQ模式或异步HARQ模式,能够避免由于该UE在非授权载波上竞争到的时间资源有限而造成该UE无法进行重传,从而增强该UE在非授权载波上进行上行传输的灵活性,并且使得网络设备能够对接收到的该UE多次发送的上行数据进行合并处理,提高数据传输性能和系统整体性能。
图6示出了本发明实施例提供的另一在LAA系统中用于传输上行数据的方法200。该方法200可以由网络设备执行,其中,该网络设备可以为基站或其它网元,本发明实施例对此不做限定。
S210,确定为UE在非授权载波上的上行传输配置同步混合自动重传请求HARQ模式和异步HARQ模式;
S220,向该UE发送模式配置指示信息,该模式配置指示信息用于指示为该非授权载波上的上行传输配置该同步HARQ模式和该异步HARQ模式,以便于该UE在该非授权载波上采用该同步HARQ模式或该异步HARQ模式进行上行传输。
因此,根据本发明实施例的LAA系统中用于传输上行数据的方法,通过为用户设备在非授权载波上的上行传输配置同步HARQ模式和异步HARQ模式,以使得用户设备可以在该非授权载波上进行具体上行传输时,确定采用同步HARQ模式或异步HARQ模式,能够避免由于该UE在非授权载波上竞争到的时间资源有限而造成该UE无法进行重传,从而增强该UE在非授权载波上进行上行传输的灵活性,并且使得网络设备能够对接收到的该UE多次发送的上行数据进行合并处理,提高数据传输性能和系统整 体性能。
作为一个可选实施例,该模式配置指示信息还用于指示该同步HARQ模式与该异步HARQ模式之间的模式切换。
作为一个可选实施例,S220,向该UE发送模式配置指示信息,包括:
向该UE发送系统消息,该系统消息中携带该模式配置指示信息;或
向该UE发送RRC信令,该RRC信令中携带该模式配置指示信息;或
向该UE发送DCI,该DCI中携带该模式配置指示信息。
作为另一个可选实施例,该方法200还包括:确定采用该异步HARQ模式接收该UE在该非授权载波上重传的上行数据。
具体地,该网络设备可以接收该UE在第一子帧上传输的上行数据,对接收到的该上行数据进行解调校验处理,以确定是否成功接收该第一子帧上传输的该上行数据。该网络设备可以根据该同步HARQ模式,确定与该第一子帧对应的反馈子帧,并且在该反馈子帧上向该UE发送用于指示是否成功接收该上行数据的反馈信息,例如,ACK/NACK。可选地,如果该网络设备未成功接收该上行数据,则该网络设备可以在该反馈子帧时向该UE发送NACK,以使得该UE根据该NACK确定需要重传该上行数据。相应地,在确定采用该异步HARQ模式接收该UE在该非授权载波上重传的上行数据之前,该方法200还可以包括:根据同步HARQ模式,在与该第一子帧对应的反馈子帧上向该UE发送反馈信息,其中,该反馈信息用于指示该网络设备未成功接收该UE传输的该上行数据。
在本发明实施例中,该网络设备可以通过多种方式确定采用异步HARQ模式接收该UE重传的该上行数据。作为一个可选实施例,该网络设备可以根据该UE的配置,确定采用该异步HARQ模式接收该UE重传的该上行数据。作为另一个可选实施例,该确定采用该异步HARQ模式接收该UE在该非授权载波上重传的上行数据,包括:
接收该UE发送的第一指示信息,该第一指示信息用于指示该UE采用该异步HARQ模式重传该上行数据;
根据该第一指示信息,确定采用该异步HARQ模式接收该UE在该非授权载波上重传的上行数据。
此时,可以由UE竞争该非授权载波上的资源,并且当UE确定未竞争到采用同步HARQ模式在该非授权载波上重传该上行数据所需的资源时, 该UE可以确定采用异步HARQ模式进行该上行数据的重传,并向该网络设备发送该第一指示信息,以指示该网络设备根据异步HARQ模式接收该UE重传的该上行数据,但本发明实施例不限于此。
作为另一个可选实施例,该确定采用该异步HARQ模式接收该UE在该非授权载波上重传的上行数据,包括:
在确定未竞争到所需资源时,确定采用该异步HARQ模式接收该UE在该非授权载波上重传的上行数据,其中,该所需资源为采用该同步HARQ模式重传该上行数据时所需的该非授权载波上的资源;
相应地,该方法200还包括:向该UE发送第二指示信息,该第二指示信息用于指示该UE采用该异步HARQ模式重传该上行数据。
此时,该网络设备在确定对该非授权载波上的所需资源的竞争失败时,确定采用异步HARQ模式进行该上行数据的重传,并向该UE发送该第二指示信息,以指示该UE采用异步HARQ模式重传该上行数据,即由同步HARQ模式切换到异步HARQ模式。
在本发明实施例中,该网络设备可以多种方式发送该第二指示信息。作为一个可选实施例,该第二指示信息携带在下行控制信息中。此时,该第二指示信息包括下列字段中的至少一种:HARQ模式字段和HARQ映射字段,其中,该HARQ模式字段用于指示同步HARQ模式或异步HARQ模式,该HARQ映射字段用于指示HARQ进程的编号。
该网络设备可以通过多种方式确定未竞争到该非授权载波上的所需资源。可选地,可以由网络设备侦听该非授权载波的信道,并且根据侦听结果确定是否竞争到该非授权载波上的所需资源;或者,可以由UE侦听该非授权载波的信道,并且该UE在确定该UE未竞争到该非授权载波上的所需资源时,向该网络设备发送该竞争失败指示信息,相应地,该网络设备可以根据该竞争失败指示信息,确定未竞争到该非授权载波上的所需资源,但本发明实施例不限于此。
作为一个可选实施例,该确定未竞争到所需资源,包括:
接收该UE发送的第三指示信息,该第三指示信息用于指示该UE未竞争到该非授权载波上的该所需资源;
根据该第三指示信息,确定未竞争到该非授权载波上的该所需资源。
在本发明实施例中,该网络设备可以只要确定未竞争到该非授权载波上 的所需资源,就确定需要采用异步HARQ模式进行该上行数据的重传。作为另一个可选实施例,该在确定未竞争到所需资源时,确定采用该异步HARQ模式接收该UE在该非授权载波上重传的上行数据,包括:

相应地,该方法200还包括:
在确定该所需资源中的未竞争到的部分在该所需资源中所占的比例低于该阈值时,确定采用该同步HARQ模式接收该UE在该非授权载波上重传的上行数据。
具体地,该网络设备可以确定该非授权载波上的所需资源中的未竞争到的部分在该所需资源中所占的比例,并且只有在确定未竞争到的部分在该所需资源中所占的比例超过一定阈值时,才确定需要采用异步HARQ模式进行该上行数据的重传;否则,例如,该网络设备确定未竞争到该非授权载波上的所需资源的任何部分,该网络设备可以确定采用同步HARQ模式进行该上行数据的重传。可选地,该UE可以对该上行数据中与该未竞争到的部分相对应的部分进行打孔处理,并且采用该第一重传子帧中的竞争到的资源重传该经过打孔处理的该上行数据。此时,该网络设备在接收到该经过打孔处理的该上行数据之后,仍然可以将接收到的该UE之前传输的该上行数据与接收到的该UE重传的经过打孔处理的该上行数据进行合并处理,但本发明实施例不限于此。
因此,根据本发明实施例的LAA系统中用于传输上行数据的方法,通过为用户设备在非授权载波上的上行传输配置同步HARQ模式和异步HARQ模式,以使得用户设备可以在该非授权载波上进行具体上行传输时,确定采用同步HARQ模式或异步HARQ模式,能够避免由于该UE在非授权载波上竞争到的时间资源有限而造成该UE无法进行重传,从而增强该UE在非授权载波上进行上行传输的灵活性,并且使得网络设备能够对接收到的该UE多次发送的上行数据进行合并处理,提高数据传输性能和系统整体性能。

S310,确定未竞争到所需资源,其中,该所需资源为UE采用上行HARQ模式重传上行数据时所需的非授权载波上的资源。
该上行HARQ模式适用于该UE在非授权载波上的上行传输。可选地,该上行HARQ模式可以为同步HARQ模式或异步HARQ模式,该上行HARQ模式可以由网络设备配置,但本发明实施例不限于此。
具体地,该UE可以在第一子帧上向网络设备传输上行数据(采用该非授权载波或其它载波),并且该UE在与该第一子帧对应的反馈子帧上接收到该网络设备发送的用于指示未成功接收该上行数据的反馈信息(例如NACK),则该UE可以根据该同步HARQ模式确定与该第一子帧对应的第一重传子帧,并且确定在该第一重传子帧上重传该上行数据。
进一步地,该UE可以确定是否竞争到该非授权载波上的所需资源,其中,该所需资源位于该第一重传子帧内。如果该UE确定未竞争到该非授权载波上的所需资源,则可以确定对该上行数据进行打孔处理。该UE确定未竞争到该非授权载波上的所需资源的方式可以参考方法100,为了简洁,这里不再赘述。

因此,根据本发明实施例的用于传输上行数据的方法,通过UE在确定未竞争到采用上行HARQ模式在非授权载波上重传上行数据时所需的资源时,对该上行数据进行打孔处理,能够实现LAA系统中的非授权载波上的上行数据重传,操作简单,易于实现,从而提高LAA系统的可行性和系统性能。
可选地,该UE可以对该上行数据中的所有部分均进行打孔处理。作为另一个可选实施例,S310,确定未竞争到所需资源,包括:
确定未竞争到该所需资源中的一部分;
相应地,S320,对该上行数据进行打孔处理,包括:
根据该所需资源中未竞争到的部分,对该上行数据进行打孔处理。
此时,该方法300还包括:
采用该所需资源中的竞争到的部分,向网络设备重传经过该打孔处理的该上行数据。
此时,该UE可以对该上行数据中的与该未竞争到的资源对应的部分进行打孔处理,并向该网络设备重传经过该打孔处理后的该上行数据。这样, 该网络设备可以对接收到的该UE之前传输的该上行数据和接收到的该UE重传的经过打孔处理的该上行数据进行合并处理,以提高该网络设备成功接收该上行数据的可能性,从而提高LAA系统的数据传输性能。
在本发明实施例中,该UE可以在确定未竞争到非授权载波上的所需资源时,根据自身配置确定对待重传的该上行数据进行打孔处理,或者该UE也可以根据网络设备的指示,确定对该上行数据进行打孔处理,本发明实施例不限于此。

此时,该方法400还包括:接收该UE采用该所需资源中的竞争到的部分重传的经过该打孔处理的该上行数据。
作为另一个可选实施例,该第一指示信息携带在下行控制信息中,并且该第一指示信息包括下列字段中的至少一种:载波指示字段和打孔配置字段,其中,该载波指示字段用于指示该非授权载波,该打孔配置字段用于指示打孔起始位置和打孔长度。
作为另一个可选实施例,S410,确定未竞争到所需资源,包括:
接收该UE发送的第二指示信息,该第二指示信息用于指示该UE未竞争到该所需资源;
根据该第二指示信息,确定未竞争到该所需资源。
因此,根据本发明实施例的用于传输上行数据的方法,通过UE在确定 未竞争到采用上行HARQ模式在非授权载波上重传上行数据时所需的资源时,对该上行数据进行打孔处理,能够实现LAA系统中的非授权载波上的上行数据重传,操作简单,易于实现,从而提高LAA系统的可行性和系统性能。
下面将结合具体例子对本发明实施例提供的用于传输上行数据的方法做更详细的说明。图9是本发明另一实施例提供的用于传输上行数据的方法500的示意性流程图。为了方便描述,在本实施例中,假设网络设备为eNB,第一子帧为子帧n,第一重传子帧为子帧n+k,第三子帧为子帧n+k′,但本发明实施例不限于此。
S510,UE在子帧n采用非授权载波向eNB传输上行数据。
可选地,该UE可以竞争该非授权载波上的资源,并且当竞争到非授权载波在子帧n上的资源时,在该子帧n采用该非授权载波向该eNB传输上行数据。作为另一个可选实施例,该eNB可以竞争该非授权载波上的资源,并且在竞争到该非授权载波在子帧n上的资源时,对该UE进行调度,以使得该UE在该子帧n采用该非授权载波向该eNB传输上行数据,但本发明实施例不限于此。
S520,eNB根据该同步HARQ模式,确定与该子帧n对应的反馈子帧,并且在该反馈子帧上向UE发送用于指示该eNB未成功接收该上行数据的反馈信息。
该eNB在接收到该UE在子帧n上采用非授权载波传输的该上行数据时,可以对该上行数据进行解调校验处理,以确定是否成功接收该上行数据。该eNB还可以根据该同步HARQ模式,确定与该子帧n对应的反馈子帧,并且在该反馈子帧上向该UE发送用于指示是否成功接收该上行数据的反馈信息;类似地,该UE也可以根据该同步HARQ模式,确定与该子帧n对应的反馈子帧,并且在该反馈子帧上接收该eNB发送的该反馈信息。可选地,该eNB可以在该反馈子帧上采用授权载波向该UE发送反馈信息,也可以采用用于传输该上行数据的该非授权载波发送该反馈信息,或者采用不同于该非授权载波的其它非授权载波发送该反馈信息,本发明实施例不限于此。
作为一个可选实施例,如果该eNB确定成功接收该上行数据,则该eNB可以向该UE发送用于指示成功接收该上行数据的反馈信息,例如,确认(ACK)消息,此时,本次数据传输结束。作为另一个可选实施例,如果该 eNB确定未成功接收该上行数据,则eNB可以向该UE发送用于指示未成功接收该上行数据的反馈信息,例如,否认(NACK)消息。此时,该UE在接收到该用于指示未成功接收该上行数据的反馈信息之后,可以根据该反馈信息,确定需要重传该上行数据,但本发明实施例不限于此。
S530,UE根据该同步HARQ模式,确定与该反馈子帧对应的第一重传子帧(即与该子帧n对应的第一重传子帧)为子帧n+k,并且竞争该非授权载波在子帧n+k上的资源。
可选地,该反馈子帧可以为子帧n+4,该第一重传子帧可以为子帧n+8,即k=8,但本发明实施例对该反馈子帧与该子帧n之间的间隔以及该第一重传子帧与该子帧n之间的间隔不做限定。
作为一个可选实施例,如果该UE竞争到该非授权载波在子帧n+k上的所需资源,则该UE可以根据该同步HARQ模式,在该子帧n+k上采用该非授权载波向eNB重传该上行数据。作为另一个可选实施例,如果该UE未竞争到该非授权载波在子帧n+k上的所需资源,则该UE可以确定由该同步HARQ模式切换到异步HARQ模式,并根据异步HARQ模式进行上行数据的重传,但本发明实施例不限于此。
作为一个可选例子,该UE未竞争到该非授权载波在子帧n+k上的所需资源可以指该UE竞争到的该非授权载波的时间资源仅包括该子帧n+k中的部分时间资源,并且该UE未竞争到该非授权载波在该子帧n+k中的另一部分时间资源,其中,该UE竞争到的该子帧n+k中的部分时间资源低于采用该非授权载波重传该上行数据所需的时间资源。这样,该UE可以确定由该同步HARQ模式切换到异步HARQ模式,并且执行S570;或者,该UE可以在同步HARQ模式下执行S590,其中,该UE可以只要竞争到该非授权载波在子帧n+k中的部分时间资源,则执行S590,或者可以仅在该竞争到的资源在所需资源中所占的比例超过预设阈值时才执行S590,并且在该竞争到的资源在所需资源中所占的比例未超过该预设阈值时执行S570,以提高该eNB成功接收该上行数据的概率,但本发明实施例不限于此。
作为另一个可选例子,该UE未竞争到该非授权载波在子帧n+k上的所需资源可以指该UE未竞争到该非授权载波上的资源,或者指该UE竞争到的该非授权载波上的资源不包括位于该子帧n+k中的资源,或者指该UE竞争到的该非授权载波上的位于该子帧n+k中的资源的量不够用于重传该上 行数据。此时,该UE可以确定由该同步HARQ模式切换到异步HARQ模式,并且执行S570,但本发明实施例不限于此。
在本实施例中,该UE可以在确定未竞争到该非授权载波在子帧n+k上的所需资源之后,自行确定由同步HARQ模式切换到异步HARQ模式,即执行S560和S570,也可以根据eNB的指示由同步HARQ模式切换到异步HARQ模式,即执行S540、S550和S570,本发明实施例对此不做限定。
S540,UE向eNB发送竞争失败指示,该竞争失败指示用于指示该UE未竞争到该非授权载波在第一重传子帧(子帧n+k)上的所需资源。
该UE可以采用授权载波向该eNB发送竞争失败指示,也可以采用不同于该非授权载波的其他非授权载波发送该竞争失败指示,还可以采用该非授权载波的竞争到的时间资源发送该竞争失败指示,本发明实施例对此不作限定。
S550,eNB在接收到该竞争失败指示之后,确定该UE需要根据异步HARQ模式进行数据重传,并且向UE发送第一指示信息,其中,该第一指示信息用于指示该UE根据该异步HARQ模式进行数据重传。
该eNB可以采用授权载波向该UE发送该第一指示信息,或者采用该非授权载波发送该第一指示信息,或者采用不同于该授权载波的其它非授权载波发送该第一指示信息。此外,该第一指示信息可以携带在DCI或RRC信令中发送,其中,该DCI的格式可以如表1所示,但本发明实施例不限于此。
具体地,如果该UE只有一份需要采用异步HARQ模式重传的上行数据,即该UE只有一个子帧上传输的上行数据需要采用异步HARQ模式重传,则在S550中,该eNB可以确定该UE需要根据异步HARQ模式进行数据重传,并且该第一指示信息可以具体用于指示该UE采用异步HARQ模式。可选地,该第一指示信息可以占用1个比特位,在一个具体例子中,该比特位的值置为0用于指示该UE不进行HARQ模式的切换或用于指示该UE采用同步HARQ模式,该比特位的值置为1用于指示该UE进行HARQ模式的切换或指示该UE采用异步HARQ模式;或者反之,但本发明实施例对该第一指示信息的具体实现不做限定。
如果该UE有多份需要采用异步HARQ模式重传的上行数据,其中,不同上行数据对应于不同的传输子帧,则在S550中,该eNB可以确定该UE需要根据异步HARQ模式进行数据重传,并且进一步确定待重传的上行数 据对应的具体HARQ进程。这样,该第一指示信息可以进一步用于指示该UE采用异步HARQ模式重传对应于哪一个HARQ进程的上行数据,但本发明实施例对该第一指示信息的具体实现不做限定。
S560,UE确定采用异步HARQ模式重传上行数据,并且向该eNB发送第二指示信息,该第二指示信息用于指示该UE采用异步HARQ模式重传该上行数据。
可选地,该第二指示信息可以携带在UCI中发送。该第二指示信息的具体实现可以与该第一指示信息类似,为了简洁,这里不再赘述。该eNB接收到该第二指示信息之后,可以根据该异步HARQ模式或根据该异步HARQ模式和HARQ进程号,确定在子帧n+k′上接收该UE重传的该上行数据,但本发明实施例不限于此。
S570,该UE根据该异步HARQ模式或根据异步HARQ模式和HARQ进程号,确定与该反馈子帧对应的第二重传子帧(即与子帧n对应的第二重传子帧)为子帧n+k′。
S580,该UE在竞争到该非授权载波在该子帧n+k′上的所需资源时,在子帧n+k′上采用该非授权载波重传该上行数据。
k′可以大于或小于k,但本发明实施例对k′与k之间的差值不做限定。可选地,在S580中,如果该UE已经竞争到该非授权载波在子帧n+k′上的所需资源,则该UE可以直接在该子帧n+k′上采用该非授权载波进行数据重传。如果该UE尚未竞争到该非授权载波在子帧n+k′上的所需资源,则该UE可以进行资源竞争,并且在竞争到该非授权载波在子帧n+k′上的所需资源时,采用竞争到的该非授权载波上的位于该子帧n+k′中的资源重传该上行数据,但本发明实施例不限于此。
S590,该UE对该上行数据进行打孔处理,并且在该子帧n+k中采用该非授权载波重传该经过打孔处理的该上行数据。
具体地,该UE可以对该上行数据中包括的与未竞争到的资源对应的数据进行打孔处理,但本发明实施例不限于此。
因此,根据本发明实施例的LAA系统中用于传输上行数据的方法,通过为用户设备在非授权载波上的上行传输配置同步HARQ模式和异步HARQ模式,以使得用户设备可以在该非授权载波上进行具体上行传输时,确定采用同步HARQ模式或异步HARQ模式,能够避免由于该UE在非授 权载波上竞争到的时间资源有限而造成该UE无法进行重传,从而增强该UE在非授权载波上进行上行传输的灵活性,并且使得网络设备能够对接收到的该UE多次发送的上行数据进行合并处理,提高数据传输性能和系统整体性能。
