Description

基于非授权传输的数据传输方法、装置、设备和存储介质
本申请要求于2017年9月30日提交中国专利局、申请号为201710920136.8、申请名称为“基于非授权传输的数据传输方法、装置、设备和存储介质”的中国专利申请的优先权，以及于2017年8月24日提交中国专利局、申请号为201710735037.2、申请名称为“一种通信的方法和设备”的中国专利申请的优先权，它们的全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术，尤其涉及一种基于非授权传输的数据传输方法、装置、设备和存储介质。
背景技术
随着移动通信技术的发展，下一代移动通信系统不仅支持传统通信，还支持海量物联网通信(massive Machine Type Communication，mMTC)，由于业务种类的不同，对网络需求存在很大差异，例如：可靠传输，时延不敏感；或者，低时延高可靠传输等。对低延迟、高可靠传输类的业务，不仅要求传输时延短，而且要求可靠，比如车辆对车辆(Vehicle to Vehicle，V2V)业务。如果传输不可靠，会导致重传(retransmission)。
在长期演进(Long Term Evolution，LTE)系统中，当用户设备(User Equipment，UE)有上行数据时，均是通过基于授权的传输的方式进行，具体的，UE可以首先发送一个调度请求(Scheduling Request，SR)以通知基站需要传输的数据量，基站收到SR命令后，向UE发送上行调度消息。相比上述的基于授权(Grant-based，也可以称为with grant,或UL transmission with grant等)的传输方法，下一代无线通信网络，例如：新空口(New Radio，NR)引入了非授权(Grant-free，也可以称为grantless,或without grant,或UL transmission without grant等)传输方法，基站先为UE划分一片或多片非授权传输区域(Grant-free Transmission Area，GFTA)，也可称为Grant-free资源(如Grant-free resouces)，UE在非授权传输区域中直接使用特定的传输资源发送上行数据(如上行Grant-free数据)，不需要经历从业务请求到基站上行授权的过程。
对于NR Grant-free传输中UE发送的上行数据，基站和UE需要知道在何处资源发送/接收所述上行数据的响应消息，如肯定响应(Acknowledge，ACK)或否定响应(Negative Acknowledge，NACK)。文献提出NR Grant-free传输可以使用传统的物理HARQ指示信道(Physical Hybrid ARQ Indicator Channel，PHICH)资源进行上行数据的响应。这里PHICH资源可以用于基站向UE确认是否收到UE发送的上行数据，即响应资源。在LTE中，上行数据所使用的PHICH资源的位置对于基站和UE来说可以通过一对序列索引
Figure PCTCN2018101753-appb-000001
进行指示。按照目前LTE协议规定，如果UE没收接收到物理下行控制信道(Physical Downlink Control Channel,PDCCH)资源上发送的调度信息，如上行调度信息，那么可以将n DMRS设置为0。因此在NR的Grant-free传输中，基站和UE在计算发送/接收上行数据的响应消息所使用的PHICH资源时，也可能将n DMRS设置0。
然而，按照上述方案如果Grant-free传输中多个UE均使用n DMRS＝0，可能会发生多个UE即便使用不同的I PRB_RA，但由于n DMRS相同，而使PHICH资源位置序列索引相同的情况发生，可能导致多个UE中PHICH资源位置序列索引冲突的UE无法正确接收上行数据的响应消息，即多个UE使用相同的PHICH资源接收上行数据的响应消息，导致UE可能无法正确解调上行数据的响应消息。
发明内容
本申请提供一种基于非授权传输的数据传输方法、装置、设备和存储介质，用于解决多个UE使用相同的响应资源接收上行数据的响应消息，导致UE可能无法正确解调上行数据的响应消息的问题。

具体实施方式
在频分双工(Frequency DivisionDuplex，FDD)的LTE系统中，从时域角度，一个帧(frame)长度为10ms，其具体可以细分为10个子帧(subframe)，每个subframe长度为1ms。图1为FDD的LTE系统中的传输资源示意图，如图1所示，每个subframe可以分为两个时隙(slot，包括时隙0和时隙1，即Slot 0和Slot 1)，各0.5ms；对于一个时隙，可以包括若干正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号(Symbol)，用来承载有用信息。在LTE中，每个时隙可以包括7个OFDM符号，而一个OFDM symbol则为时域上的最小单元。在NR中，每个时隙可以包括7或14个OFDM符号，一个时隙下又可以细分为若干个微时隙(mini-slot)，每个mini-slot至少持续一个OFDM符号长度，也可以持续多个OFDM符号长度。
对于NR Grant-free传输中UE发送的上行数据，基站和UE需要知道在何处资源发送/接收所述上行数据的响应消息，如肯定响应(Acknowledge，ACK)或否定响应(Negative Acknowledge，NACK)。因此提出NR Grant-free传输可以使用传统的物理HARQ指示信道(Physical Hybrid ARQ Indicator Channel，PHICH)资源进行上行数据的响应，或其他的PDCCH资源进行上行数据的响应。这里PHICH资源或PDCCH资源可以用于基站向UE确认是否收到UE发送的上行数据，即响应资源。LTE中，上行数据所使用的响应资源(如PHICH资源)的位置对于基站和UE来说可以通过一对序列索引
Figure PCTCN2018101753-appb-000002
进行指示。具体的，
Figure PCTCN2018101753-appb-000003
为PHICH组号(PHICH group number)，
Figure PCTCN2018101753-appb-000004
为PHICH组内的正交序列索引(orthogonal sequence index within the group)。所述序列索引
Figure PCTCN2018101753-appb-000005
可以由基站/UE通过LTE协议中规定的公式1。计算获得。简单来说，所述PHICH资源位置的序列索引除与一些基站事先向UE配置的参数(相对静态的参数)相关外，如带宽、循环前缀 (cyclic prefix，CP)、时分双工(Time DivisionDuplex，TDD)配置(TDD configuration)、第一或第二个传输块(Transport Block，TB)等；还可以跟一些相对动态的参数相关，如解调参考信号(Demodulation Reference Signal，DMRS)的参数(如n DMRS)和上行资源分配(如I PRB_RA，PRB最低索引)，即上行数据传输在第一个时隙的最低位物理资源块(Physical Resource Block，PRB)索引，也称为lowest PRB index。由此可见，基站在同一时刻调度的多个UE所使用的PHICH资源主要依靠公式1中相对动态的参数来区分，即n DMRS和I PRB_RA。
Figure PCTCN2018101753-appb-000006
根据公式1中所示的公式，如果仅根据I PRB_RA计算PHICH资源位置序列索引
Figure PCTCN2018101753-appb-000007
会发生当两个UE发送的上行数据所使用的I PRB_RA不同，但所述两个UE分别使用的I PRB_RA恰好满足特定的间隔(即相距一定的PRB)，则两个UE根据公式计算的PHICH资源位置序列索引可能相同的情况，即不同UE使用的PHICH资源位置可能会发生碰撞。因此LTE中引入了DMRS参数(如n DMRS)，通过DMRS参数的正交性将PHICH资源位置序列索引进一步区分开。在LTE中，基站通过向UE发送的上行调度信息中的Cyclic Shift for DMRS field来指示n DMRS，如表格1所示，Cyclic Shift for DMRS field在PDCCH中可以占据3比特(bits)指示位，可以用于映射n DMRS(0～7)。对于前述的两个UE的I PRB_RA不同但PHICH资源位置序列索引相同的情况，基站可以为所述两个UE分配不同的n DMRS，以进一步区分所述两个UE使用的PHICH资源。
表格1

Figure PCTCN2018101753-appb-000009
NR的Grant-free传输中，由于UE在发送上行数据之前不会接收到来自基站的上行调度信息，因此UE无法通过上行调度信息显性的获得用于计算接收上行数据的响应消息所需的DMRS参数n DMRS，导致无法获知在何处接收到基站发送的Grant-free传输上行数据的响应消息，因此需要解决。目前的方案中，按照LTE协议规定，如果UE没收接收到PDCCH(如上行调度信息)，那么可以将n DMRS设置为0。因此在NR的Grant-free传输中，基站和UE在计算发送/接收上行数据的响应消息所使用的PHICH资源时，也可能将n DMRS设置0。
多个UE所使用的PHICH资源发生冲突需要满足以下条件：不同UE之间所使用的PRB最低索引之间的间隔(PRB gap)满足公式2。
Figure PCTCN2018101753-appb-000010
如公式2所示，M为整数；
Figure PCTCN2018101753-appb-000011
为系统带宽中所拥有的PHICH资源组数量(PHICH group number)，该值为基站预先配置好的参数，比如为3；
Figure PCTCN2018101753-appb-000012
为扩频因子，当使用正常循环前缀时该值可以设定为4。由此可见，在n DMRS相同的情况下，当UE发送的Grant-free传输的上行数据的PRB最低索引I PRB_RA(lowest PRB index)与其他UE发送的上行数据的PRB最低索引I PRB_RA恰好相距为24(M*3*2*4)个PRB(或其整数倍)时，所述UE的上行数据的响应消息所使用的PHICH资源会与其他UE的上行数据的响应消息所使用的PHICH资源冲突，即会发生碰撞。这里其他UE发送的上行数据可以为基于非授权的传输(Grant-free传输)的数据，也可以为基于授权的传输(Grant-based传输)的数据。
综上所述，如果Grant-free传输中多个UE均使用n DMRS＝0，可能会发生多个UE即便使用不同的I PRB_RA，但由于n DMRS相同，而致使PHICH资源位置序列索引相同的情况发生，这可能会导致所述多个UE中PHICH资源位置序列索引冲突的UE无法正确接收上行数据的响应消息，即所述多个UE使用相同的PHICH资源接收上行数据的响应消息，导致所述多个UE可能无法正确解调自己的上行数据的响应消息。
基于上述存在的问题，本申请提出一种基于非授权传输的数据传输方法，对上行非授权传输响应的资源进行配置，使得网络设备和用户设备可以明确其使用的n DMRS，进而计算出在何处发送或者接收上行数据的响应消息。
图2为本申请提供的基于非授权传输的数据传输方法实施例一的交互流程图，如图2所示，该基于非授权传输的数据传输方法应用在网络设备和用户设备之间，该网络设备可以是基站、微基站等，用户设备包括用户的手机、电脑、智能终端等，该基于非授权传输的数据传输方法具体包括：
S101：网络设备在非授权资源中的第一资源上接收用户设备基于非授权传输发送的上行数据。
在本步骤中，网络设备预先为用户设备划分了非授权传输区域，以使用户设备可以在该非授权传输区域直接使用特定的传输资源发送上行数据，而不需要经历从业务请求到上行授权的过程，有效降低网络时延。
用户设备在网络设备分配的非授权传输区域(非授权传输资源区域)的第一资源上发送上行数据，网络设备在该第一资源上接收到该上行数据。
S102：网络设备至少根据第一资源和第一消息，确定向用户设备发送上行数据的响应消息使用的第二资源；第一消息用于指示基于非授权传输中使用的DMRS参数。
在本步骤中，由于是非授权传输，因此没有上行调度信息，用户设备并不能直接通过上行调度信息获取到DMRS参数。在该方案中网络设备可以通过预先发送第一消息给用户设备，通过该第一消息指示基于非授权传输过程中使用的DMRS参数。
用户设备在发送上行数据后，至少可以根据传输上行数据的第一资源以及根据第一消息确定的DMRS参数确定出网络设备返回上行数据的响应消息的资源位置，即第二资源。网络设备也可以根据该第一消息指示的DMRS参数和接收到上行数据的第一资源确定向用户设备发送上行数据的响应消息的资源位置，即第二资源。
在本方案各种实现方案中，应理解，该第二资源可以网络设备向用户设备发送效应消息所使用的资源，例如该第二资源可以位于物理混合自动重传请求指示信道(Physical Hybrid ARQ Indicator Channel，PHICH)上，或位于物理下行控制信道(Physical Downlink Control Channel，PDCCH)上等。
S103：网络设备在第二资源上向用户设备发送上行数据的响应消息。
网络设备确定第二资源以后，在该第二资源上向用户设备发送上行数据的响应消息，用户设备在确定出的第二资源的位置上接收该上行数据的响应消息。
在该方案的一种具体实现中，在S101之前，网络设备将第一消息发送给用户设备。该方案中，网络设备可在进行免授权传输之前很早就通过可以通过半静态信令或动态信令将第一消息携带发送给用户设备，例如可在授权传输过程中或者系统配置过程中发送第一消息，以便在进行非授权传输过程中可直接应用该第一消息确定DMRS参数。
具体的，网络设备向用户设备发送第一消息至少包括以下几种实现方案：
第一种实现方式，网络设备通过系统消息向用户设备发送所述第一消息。
在该方案中，网络设备可在系统消息的主信息块(Master InformationBlock，MIB)或者系统消息块(SystemInformation Block，SIB)中携带该第一消息。
第二种实现方式，网络设备通过无线资源控制信令向用户设备发送所述第一消息。
网络设备可在无线资源控制(Radio Resource Control，RRC)信令或者MAC控制元素(Media Access Control ControlElement，MAC CE)信令中携带该第一消息。
第三种实现方式，网络设备通过物理控制消息(L1signaling，group common PDCCH) 向用户设备发送所述第一消息。
本实施例提供的基于非授权传输的数据传输方法，网络设备可通过动态或者半静态消息中携带该第一消息，将该第一消息发送给用户设备。在非授权传输中，通过第一消息指示非授权传输过程用户设备使用的DMRS参数，使得网络设备和用户设备能够根据第一消息确定在何处发送或者接收上行数据的响应消息，避免用户设备无法正确接收解调上行数据的响应消息的问题。
在上述方案基础上，第一消息至少存在以下几种指示非授权传输过程中使用的DMRS参数的方式：第一消息指示非授权资源与DMRS参数之间的对应关系，第一消息直接指示非授权传输过程中使用的DMRS参数，或者第一消息指示非授权传输过程中使用的DMRS参数的获取规则。下面以基站和UE为例，对上述几种方式的具体实现方案进行说明。
图3为本申请提供的基于非授权传输的数据传输方法的一实例的交互流程图，如图3所示，基站向UE至少下发Grant-free传输时UE发送上行数据所使用的Grant-free资源与DMRS参数n DMRS之间的对应关系，该步骤在Grant-free传输之前，使得基站可以通过UE在何处Grant-free资源中发送上行数据，便可获知UE所使用的n DMRS，以便根据相应的n DMRS计算出基站发送上行数据的响应消息所使用的第二资源，例如PHICH资源，基站和UE在该第二资源中发送/接收上行数据的响应消息。该方案的具体步骤为：
S201：基站向UE下发第一消息，第一消息指示非授权传输中使用的DMRS参数和非授权资源的对应关系。
在本步骤中，网络设备向用户设备发送第一消息，所述第一消息携带第一指示信息，第一指示信息用于指示所述网络设备和所述用户设备在非授权传输中使用的DMRS参数与非授权资源之间的对应关系。即基站发送给UE的第一消息中的第一指示信息至少可以包括基站和UE在Grant-free传输中所使用的DMRS参数n DMRS与Grant-free资源之间的映射关系。所述DMRS参数n DMRS至少可以用于基站确认发送上行数据的响应消息所使用的资源，以及UE确认接收上行数据的响应消息所使用的资源。
在该方案的具体实现中，所述DMRS参数与非授权资源之间的对应关系包括以下至少一项：DMRS参数与非授权资源的时隙之间的对应关系；DMRS参数与非授权资源的时隙的序号之间的对应关系；DMRS参数与非授权资源的微时隙之间的对应关系；DMRS参数与非授权资源的微时隙的序号之间的对应关系；DMRS参数与非授权资源的正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号之间的对应关系；DMRS参数与非授权资源的OFDM的序号之间的对应关系。
图4为本申请提供的DMRS参数与非授权资源的一种映射关系示意图。基站和UE在Grant-free传输中所使用的DMRS参数n DMRS至少可以与Grant-free传输中UE发送的上行数据所使用的时隙(slot)序号、或微时隙(mini-slot)序号、或OFDM符号的序号相映射。如图4所示，基站和UE进行Grant-free传输时所用的Grant-free资源(如GF资源)在时域上至少包括子帧n(如subframe n)中OFDM符号4至subframe n的OFDM符号13，其中OFDM符号4可以与n DMRS＝0映射，OFDM符号6可以与n DMRS＝1映射，OFDM符号8可以与n DMRS＝2映射，OFDM符号10可以与n DMRS＝3映射，OFDM符号12可以与n DMRS＝4映射，即如果UE使用OFDM符号4发送上行数据，则其映射的n DMRS＝0，以此类推，不再一一赘述。如果UE发送上行数据所使用的Grant-free资源可以跨越多个OFDM符号所 映射的n DMRS，如UE发送的上行数据占据OFDM符号4至OFDM符号7，则所述UE使用的DMRS参数n DMRS可以为所述上行数据占据的OFDM符号中的第一个/最后一个/第N个OFDM符号所映射的n DMRS相同(N为正整数)。即假设UE发送的上行数据占据OFDM符号4至OFDM符号7，同时UE使用的n DMRS与上行数据占据的第一个OFDM符号映射的n DMRS相同，则所述UE将使用的n DMRS为OFDM符号4所映射的n DMRS＝0。
在上述过程中，需要说明的是，这里以UE发送的上行数据所使用的DMRS参数可以与OFDM符号的序号相映射为例，UE发送的上行数据所使用的DMRS参数还可以与slot序号、mini-slot(或称为non-slot)序号、或其他Grant-free资源相映射，这里不再一一赘述。
进一步的，在该方案的具体实现中，基站和UE在Grant-free传输中可以使用的DMRS参数n DMRS的集合1与其他UE在同一时刻频域上相距一定PRB正在发送的上行数据(可以为Grant-free传输或Grant-based传输)所使用的DMRS参数n DMRS的集合2可以区分开，以避免发生由于多个UE发送的上行数据使用的传输资源在频域上的间距满足一定条件，而n DMRS相同时导致的多个UE接收上行数据的响应消息所使用的PHICH资源发生冲突的情况发生，具体可参考前述公式2的条件。
图5为本申请提供的非授权资源和对应DMRS参数的示意图，一种具体的实现方案中，基站配置给Grant-free资源的循环位移n DMRS的集合1与可能发生PHICH资源碰撞的用于上行数据的传输资源所使用的循环位移n DMRS的集合2可以不同或不完全相同。如图5所示，Grant-free资源1中可以使用的循环位移n DMRS的集合1包括集合{0,1,2}，而与Grant-free资源的PRB最低索引间隔PRB gap的Grant-free资源2中可以使用的循环位移n DMRS的集合2包括集合{3,4,5}，因此在Grant-free资源1和Grant-free资源2中进行上行数据传输的UE所使用的PHICH资源不会发生冲突。需要说明的是，Grant-free资源2也可能为Grant-based的资源，只要其所使用的DMRS参数n DMRS的集合与Grant-free资源1所使用的DMRS参数n DMRS的集合不同或不完全相同即可，这里不再一一赘述。
上述步骤S201在非授权传输之前进行，例如在授权传输过程中传输，或者在UE连接时就将第一消息发送给UE对此本方案不做限制，具体的基站可通过半静态信令或者动态信令向UE传输该系统消息，例如系统消息，RRC信令，MAC CE信令或者物理控制消息等。
S210：UE在第一资源上基于非授权传输向基站发送上行数据。
UE根据基站预先分配的非授权资源区域，确定第一资源，在该第一资源上向基站发送上行数据，基站在第一资源上接收到UE发送的上行数据。
S220：基站根据第一消息和第一资源确定向UE发送上行数据的响应消息的第二资源。
在本步骤中，网络设备根据所述第一资源，以及所述网络设备和用户设备在非授权传输中使用的DMRS参数与非授权资源之间的对应关系，确定用户设备发送上行数据时采用的DMRS参数；网络设备至少根据第一资源和所述用户设备发送上行数据时采用的DMRS参数，确定向用户设备发送上行数据的响应消息使用的所述第二资源。
具体的，基站根据S201中的第一消息，以及S210中接收到的UE向基站发送的上行数据的位置(即第一资源)确认向UE返回上行数据的响应消息所使用的第二资源。具体的，如图4所示，假设基站接收到的上行数据位置(如U，即上行数据所占据的Grant-free 资源)为subframe n中的OFDM符号4和OFDM符号5，同时第一消息中指示基站和UE将使用的DMRS参数n DMRS与上行数据占据的第一个OFDM符号所映射的n DMRS(如OFDM符号4映射的n DMRS＝0)相同，则基站可以确认将使用DMRS参数n DMRS＝0来计算发送所述上行数据的响应消息所使用的第二资源。
S230：UE根据第一消息和第一资源确定基站返回上行数据的响应消息的第二资源。
在本步骤中，用户设备至少根据第一资源和网络设备和用户设备在非授权传输中使用的DMRS参数与非授权资源之间的对应关系，确定发送上行数据时采用的DMRS参数；用户设备根据发送上行数据时采用的DMRS参数，确定网络设备发送所述上行数据的响应消息使用的所述第二资源。
具体的，UE根据S201中的第一消息，以及S210中发送的上行数据位置确认接收到上行数据的响应消息所使用的PHICH资源或PDCCH资源。具体的，如图4所述，假设UE发送的上行数据位置(如U)为为subframe n中的OFDM符号4和OFDM符号5，同时第一消息中指示基站和UE将使用的DMRS参数n DMRS与上行数据占据的第一个OFDM符号所映射的n DMRS(如OFDM符号4映射的n DMRS＝0)相同，则UE可以确认将使用DMRS参数n DMRS＝0来计算接收所述上行数据的响应消息所使用的第二资源。
应理解，上述S230和S220并没有先后顺序的关系，只要基站在发送上行数据的响应消息之前确定出第二资源，UE在接收上行数据的响应消息之前确定出第二资源即可。
S240：基站在第二资源上向UE发送上行数据的响应消息。
基站向UE发送上行数据的响应消息。具体的，基站在根据步骤220中所确认的第二资源上向UE发送上行数据的响应消息。相应的，UE在根据步骤230中所确认的第二资源中接收基站发送的上行数据的响应消息。
本实例提供的基于非授权传输的数据传输方法，基站通过接收到UE发送的上行数据的第一资源，以及根据非授权资源和DMRS参数之间的对应关系确定出的UE发送上行数据采用的DMRS参数，可以确认出向UE返回上行数据的响应消息将使用的第二资源，UE也根据第一消息和第一资源确定出基站发送上行数据的响应消息的第二资源，并在该资源上接收基站发送的上行数据的响应消息，不需要调度也不需要额外的指示，节省信令开销的同时，提高传输效率和可靠性，避免UE不能正确解调响应消息的问题。
图6为本申请提供的基于非授权传输的数据传输方法的又一实例的交互流程图，如图6所示，与图3所示实例不同，本方案，网络设备可直接通过第一消息指示网络设备和用户设备在进行非授权传输时，所使用的DMRS参数n DMRS，即对n DMRS进行预配置。该方案的具体步骤包括：
S301：基站向UE下发第一消息，第一消息指示非授权传输中使用的DMRS参数。
在本步骤中，其含义是网络设备向用户设备发送携带第二指示信息的第一信息，第二指示信息用于指示网络设备和所述用户设备在非授权传输中使用的DMRS参数。
该方案中，基站向UE下发第一消息，所述第一消息携带第二指示信息，以指示基站和UE进行Grant-free传输中所使用的DMRS参数n DMRS，以便基站和UE确认发送/接收上行数据的响应消息所使用的第二资源。具体的，在图3所示实例中，基站和UE进行Grant-free传输之前，基站可以为UE预配置Grant-free传输中基站和UE所使用的DMRS参数n DMRS，如基站可以预配置UE1在Grant-free传输中使用的DMRS参数n DMRS＝0，UE2 在Grant-free传输中使用的DMRS参数n DMRS＝1等等。进一步的，Grant-free传输中不同的UE使用的DMRS参数n DMRS可以不完全相同。
可选的，图7为本申请提供的UE分组和对应DMRS参数的示意图，基站可以将使用同一Grant-free资源的UE分组，处于相同分组的UE可以使用相同的DMRS参数n DMRS集合，但同一分组内的不同UE之间可以使用不同的DMRS参数n DMRS。可选的，属于不同分组的UE也可以使用不同的DMRS参数n DMRS。如图7所示，UE1至UE6可以使用Grant-free资源1进行Grant-free传输，所述Grant-free资源1可以映射的DMRS参数n DMRS集合＝{0,1,2,3}；进一步的，UE1至UE6可以分为两组，其中UE1至UE3为一组，其可以使用的DMRS参数包括n DMRS＝{0,2}，如UE1使用的n DMRS＝0，UE2使用的n DMRS＝1等；UE4～UE6可以为另一组，其可以使用的DMRS参数包括n DMRS＝{1,3}，如UE4使用n DMRS＝2，UE5使用n DMRS＝3等。
与前述任一实施例类似，这里的基站可以通过半静态信令或动态信令向UE发送第一消息，这里所述的半静态信令或动态信令与本申请实施例一中所述第一消息可能使用的信令相同，如系统消息MIB、SIB、RRC信令、MAC CE信令或物理控制消息等，因此不再赘述。
S310：UE在第一资源上基于非授权传输向基站发送上行数据。
UE根据基站预先分配的非授权资源区域，确定第一资源，在该第一资源上向基站发送上行数据，基站在第一资源上接收到UE发送的上行数据。
S320：基站根据第一消息和第一资源确定向UE发送上行数据的响应消息的第二资源。
该步骤的含义为：网络设备至少根据所述第一资源和所述网络设备和所述用户设备在非授权传输中使用的DMRS参数，确定向所述用户设备发送所述上行数据的响应消息使用的所述第二资源。
具体的，基站可以根据S301中的第一消息确认发送上行数据的响应消息所使用的第二资源。具体的，基站可以根据接收到的上行数据确认所述上行数据的发送者(如UE1)，使得基站可以确认UE1使用的DMRS参数n DMRS(如n DMRS＝2)，进而计算确认发送上行数据的响应消息使用的第二资源。
S330：UE根据第一消息和第一资源确定基站返回上行数据的响应消息的第二资源。
本步骤的含义是：用户设备至少根据所述第一资源和所述网络设备和所述用户设备在非授权传输中使用的所述DMRS参数，确定所述网络设备发送所述上行数据的响应消息使用的所述第二资源。
具体的，UE可以根据步S301中的第一消息确认发送上行数据的响应消息所使用的第二资源。具体的，UE(如UE1)可以根据基站发送的第一消息确认其在Grant-free传输期间所使用的DMRS参数n DMRS(如n DMRS＝2)，进而计算确认接收上行数据的响应消息使用的第二资源。
与前述实例类似，这里的S320和S330也没有先后顺序的关系。
S340：基站在第二资源上向UE发送上行数据的响应消息。
基站向UE发送上行数据的响应消息。具体的，基站在根据步骤320中所确认的第二资源上向UE发送上行数据的响应消息。相应的，UE在根据步骤330中所确认的第二资源中接收基站发送的上行数据的响应消息。
本申请实施例中各实例的好处是通过基站向UE预配置Grant-free传输中基站将使用DMRS参数n DMRS，UE可以清楚的知道在何处PHICH资源中去接收Grant-free传输的上行数据的响应消息，有效避免多个UE可能无法正确解调上行数据的响应消息的问题。该方案中，基站如果想更改其所使用的DMRS参数n DMRS，需要向UE进行重新配置。
图8为本申请提供的基于非授权传输的数据传输方法的另一实例的交互流程图，如图8所示，与图3和图6所示实例不同，本方案，网络设备通过第一消息指示网络设备和用户设备在进行非授权传输时，所使用的DMRS参数n DMRS的获取规则。该方案的具体步骤包括：
S401：基站向UE下发第一消息，第一消息指示非授权传输中使用的DMRS参数的获取规则。
本步骤的含义是，网络设备可在第一消息中携带指示网络设备和用户设备在非授权传输中使用的DMRS参数获取规则的第三指示信息，该获取规则指示携带在所述网络设备发送给所述用户设备的上行调度信息中的DMRS参数，与所述网络设备和所述用户设备在非授权传输中使用的DMRS参数的关系。即根据该获取规则，用户设备和网络设备可以根据前面在授权传输的过程中，任一次使用的DMRS参数得到本次非授权传输使用的DMRS参数，例如：该获取规则可以是网络设备和用户设备在非授权传输过程中使用的DMRS参数与之前的倒数第二次上行调度信息中的DMRS参数相同。或者该获取规则可以是网络设备和用户设备在非授权传输过程中使用的DMRS参数为之前的倒数第三次上行调度信息中的DMRS参数加1等等，指示出能够根据之前的上行调度信息中的DMRS参数得到非授权传输时该用户设备使用的DMRS参数即可，获取规则的具体内容不做限制。
基站和UE进行Grant-free传输之前，基站通过半静态信令或动态信令向UE发送Grant-free传输中上行数据的响应准则。这里基站可能使用的半静态信令或动态信令与前述方案中介绍的半静态信令或动态信令相同，不再一一赘述。
在本方案中，获取规则可指示基站发送给UE的最后一次的上行调度信息(last grant)中携带的DMRS参数与非授权传输过程中使用的DMRS参数的关系。
一种具体实现中，图9为本申请提供的基站最后一次发送的上行调度信息中指示的DMRS参数的示意图。所述Grant-free传输中使用的DMRS参数准则可以为Grant-free传输中，基站接收到UE发送的上行数据后，基站向UE发送的上行数据的响应消息所使用的DMRS参数n DMRS可以与基站和UE进行Grant-free传输之前，基站向UE发送的最后一次上行调度信息中所指示的DMRS参数n DMRS相同。具体的，如图9所示，在一个实例中，UG1为UE1在和基站进行上行数据传输(如GF1)之前收到的最后一次上行调度信息(Uplink Grant，UL Grant，)，UG1中基站向UE指示的DMRS参数n DMRS＝2，则基站和UE1在Grant-free传输针对上行数据GF1发送的响应消息(如A/N)所使用的DMRS参数n DMRS＝2。
S410：UE在第一资源上基于非授权传输向基站发送上行数据。
UE根据基站预先分配的非授权资源区域，确定第一资源，在该第一资源上向基站发送上行数据，基站在第一资源上接收到UE发送的上行数据。
S420：基站根据第一消息、第一资源以及最后一次上行调度中为UE指示的DMRS参数，确定向UE发送上行数据的响应消息的第二资源。
本步骤的含义是：网络设备根据发送给用户设备的最后一次的上行调度信息(last grant) 中携带的DMRS参数和所述获取规则，确定用户设备发送上行数据时采用的DMRS参数，然后至少根据第一资源和用户设备发送所述上行数据时采用的DMRS参数，确定得到向用户设备发送所述上行数据的响应消息使用的第二资源。
按照上述实例，具体的，基站可以根据步骤801中的第一消息确认发送上行数据的响应消息所使用的PHICH资源或PDCCH资源。具体的，如图9所示，基站可以根据接收到的上行数据确认所述上行数据的发送者(如UE1)，同时基站和UE1在进行Grant-free传输前最后一次上行调度(Last grant)(如UG1)中使用的DMRS参数n DMRS＝2，则基站可以使用DMRS参数n DMRS＝2来确认发送上行数据的响应消息(如A/N)所使用的第二资源。
S430：UE根据第一消息、第一资源以及最后一次上行调度信息中携带的DMRS参数，确定接收基站返回的上行数据的响应消息的第二资源。
本步骤的含义是：用户设备根据最后一次(Last)接收到的上行调度信息中携带的DMRS参数和获取规则，确定发送上行数据时采用的DMRS参数，从而至少根据第一资源和发送上行数据时采用的DMRS参数，确定网络设备发送上行数据的响应消息使用的所述第二资源。
根据上述实例，如图9所示，UE(如UE1)可以确认基站和UE1在进行Grant-free传输前最后一次上行调度(如UG1)中使用的DMRS参数n DMRS＝2，则UE可以使用DMRS参数n DMRS＝2来确认接收基站发送的上行数据的响应消息(如A/N，ACK/NACK)所使用的第二资源。
S440：基站在第二资源上行向UE发送上行数据的响应消息。
基站向UE发送上行数据的响应消息。具体的，基站在根据步骤420中所确认的第二资源上向UE发送上行数据的响应消息。相应的，UE在根据步骤430中所确认的第二资源中接收基站发送的上行数据的响应消息。
本实施例提供的基于非授权传输的数据传输方法，相较于直接指示DMRS参数，本方案在基站和UE之间的开销较小，基站和UE在Grant-free传输中使用何种DMRS参数来确认上行数据的响应消息所使用的资源需要参考基站和UE在Grant-free传输之前进行的上行调度信息中的DMRS参数。通过该方式克服UE可能无法正确解调上行数据的响应消息的问题。
上述各个实施例提供基于非授权传输的数据传输方案，针对Grant-free传输中，由于没有上行调度信息，而导致UE无法获得DMRS参数n DMRS，导致无法得知在何处资源接收网络设备发送的上行数据的响应消息的问题，提出了一种上行Grant-free响应资源的配置方法，通过n DMRS与Grant-free资源建立映射、或预配置n DMRS，或网络设备下发n DMRS准则等方法，使得网络设备和UE可以明确得知其在Grant-free传输中应使用的n DMRS，进而确认在何处资源发送/接收Grant-free传输中基站发送的上行数据的响应消息，有效避免多个UE采用相同的DMRS参数造成资源冲突，UE无法正确接收解调上行数据响应消息的问题。
