Description

一种数据传输方法、装置及设备
本申请要求在2018年3月1日提交中国专利局、申请号为201810171917.6、申请名称为“一种数据传输方法、装置及设备”，以及在2018年8月16日提交中国专利局、申请号为201810937023.3、申请名称为“一种数据传输方法、装置及设备”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
本申请涉及无线通信技术领域，特别涉及一种数据传输方法、装置及设备。
背景技术
在现有的超高可靠性与超低时延(Ultra Reliable&Low Latency Communication，URLLC)中，针对半静态资源配置和资源属性动态变化之间的冲突问题，相关的技术方案如下：
如果在起始的资源上出现冲突，则根据下表1进行延迟；如果不是起始的资源上出现冲突，则放弃那些资源上的数据传输。
下表1是URLLC上行免调度传输方案中，配置不同的重复次数K，针对不同的冗余版本(redundancy version，RV)配置，所对应的传输方案。
按照目前的标准，通过无线资源控制(Radio Resource Control，RRC)配置，比如K＝4、RV＝{0 3 0 3}，时域资源位置为{起始正交频分复用(Orthogonal Frequency Division Multiplex，OFDM)符号，OFDM符号个数}，这个时域资源位置定义为一个传输机会(transmission opportunity，TO)，即完成一次重复传输的资源，K＝4意味着要进行四次重复传输，需要四个TO。这里的TO在时域上通常是连续的。
举一个例子，对应下表1中K＝4的行。当数据在第一个TO前到达时，可以使用第一个TO到第四个TO进行传输，这样会传输四次，RV为{0 3 0 3}；当数据在第一个TO后、第三个TO前到达时，可以使用第三个TO到第四个TO进行传输，这样会传输两次，RV为{0 3}；当数据在第三个TO后到达时，不进行传输。
表1：
Figure PCTCN2019075937-appb-000001
Figure PCTCN2019075937-appb-000002
现有技术的不足在于：当数据到达时间与资源分配不一致时，半静态配置的资源不足以完成K次重复传输，那么URLLC的上行传输将会被部分取消，这就将影响数据传输的可靠性。
进一步的，如果要提高可靠性，需要用动态信令分配新的资源或TO，这样又会增加信令开销和实现复杂度。

具体实施方式
发明人在发明过程中注意到：
随着移动通信业务需求的发展变化，3GPP等多个组织对未来移动通信系统都开始研究新的无线通信系统(即5G NR，5 Generation New RAT)。在5G NR系统中，一个重要的需求是低时延、高可靠的通信，出现了URLLC等传输方案。URLLC的上行传输方案，为 了降低时延，采用免调度方案，为了增加可靠性，采用重复传输方案。在URLLC的上行传输方案中，资源分配采用RRC半静态配置或半持续调度(semi-persistent schedule，SPS)，当数据到达时间与资源分配不一致时，或者出现动态信令，如用于指示某个slot为上行、下行、灵活等的时隙格式信息(slot-format information，SFI)配置信令，改变了资源属性，那么URLLC的上行传输将会被部分取消，这就将影响数据传输的可靠性，如果采用动态信令配置额外的资源，又会有增加动态信令的复杂度。因此需要解决URLLC上行传输方案中半静态资源配置和资源属性动态变化之间的冲突问题，实现数据可靠传输和降低信令复杂度。
基于此，本申请实施例中提供了URLLC中的数据传输方案，下面结合附图对本申请的具体实施方式进行说明。
在说明过程中，将分别从基站侧与终端侧的实施进行说明，然后还将给出二者配合实施的实例以更好地理解本申请实施例中给出的方案的实施。这样的说明方式并不意味着二者必须配合实施、或者必须单独实施，实际上，当终端与基站分开实施时，其也各自解决终端侧、基站侧的问题，而二者结合使用时，会获得更好的技术效果。
图1为数据传输方法实施流程示意图，如图所示，包括：
步骤101、终端通过正常资源向基站传输数据；
该步骤具体实施中，终端向基站传输数据时，是在正常资源上进行传输，不使用潜在资源；对于基站与终端之间的潜在资源，同时是基站与其他终端之间的第三种资源，即基站动态调度给终端的资源，这种资源是LTE中最常见的资源类型。
步骤102、当基站调整了正常资源的配置使得所述终端在正常资源不可用来传输数据时，或当所述正常资源不够完成配置的重复传输次数时，在潜在资源上向所述基站传输数据，其中，所述正常资源和所述潜在资源是基站为终端半静态配置用于传输数据的资源，在正常资源不可用并且潜在资源没有作为其他终端的第三种资源时，基站与终端根据相同的方式确定需要使用的用于传输数据的潜在资源。
其中，第三种资源是指基站动态调度给其它终端的资源。
例如，基站为终端配置K个用于传输数据的正常资源，以及配置N个用于传输数据的潜在资源，所述潜在资源是指在正常资源不可用并且潜在资源没有作为其他终端的第三种资源时，基站与终端根据相同的方式确定需要使用的用于传输数据的资源。
本申请实施例中对基站分配给终端的资源进行了优先级排序，基站动态调度给终端的资源为第一优先级，基站半静态配置给终端的资源为第二优先级；在第二优先级的资源中，再次进行了优先级排序，正常资源为第一优先级，潜在资源为第二优先级。本申请实施例 中涉及潜在资源的使用。第一终端的潜在资源可以是第二终端的基站动态调度给第二终端的资源。终端根据优先级，首先使用优先级高的资源进行数据传输，当基站动态调度给终端的资源、正常资源均不可用时，比如基站通过信令通知终端上述两种资源不可用，并且当潜在资源可用时，比如该潜在资源没有被作为基站动态调度给其他终端的资源或其他终端的正常资源，基站和终端会自动考虑使用潜在资源。
潜在资源的配置，通常是由基站采用RRC信令半静态配置给终端的。潜在资源可以配置在一个资源分配周期内，也可以跨资源分配周期进行配置。
潜在资源的使用，通常是不需要专门的信令通知的，但是也可以通过group-common类似的信令进行通知，通知给终端是否使用潜在资源。
实施中，所述正常资源是通过显式信令配置和通过显式/隐式信令启用的资源。例如，正常资源是通过DCI信令和/或RRC信令配置的。正常配置的资源，是指通过下行控制指示(Downlink Control Indicator，DCI)调度、半静态配置等方式指示的资源，指示包括频域和时域的具体位置，本申请实施例中主要涉及时域位置，而在不同时域位置上的频域位置可以是相同的。
潜在资源，在正常资源以外，在相同的频域位置、不同时域位置上，指定一些时域位置，作为潜在资源，正常情况下，终端和基站通信使用正常资源，不会使用潜在资源，这部分潜在资源会分配给基站和其他终端通信作为第三种资源使用，只有当如动态SFI信令引起正常资源不可用时，并且终端没有收到基站把所述潜在资源分配给其他终端作为第三种资源使用时，才会考虑使用该潜在资源进行数据传输。
具体实施中，潜在资源的通知，可以是隐式的，也可以是显式的；显式的通知即通过RRC信令或者DCI信息进行指示，隐式的通知可以如：在一个资源配置周期内正常资源后面紧跟着的N个资源单位，比如，正常资源是K个连续的slot(或者mini-slot)，潜在资源可以是这K个slot后面的连续N个slot。也即：
实施中，所述潜在资源是通过显式/隐式信令配置、和/或自动启用的资源。
实施中，在隐式配置时，是通过在一个资源配置周期内正常资源后面相邻的N个资源的方式来配置的。
具体实施中，使用潜在资源进行数据传输时，需要启用潜在资源，启用潜在资源时需要两个条件，一是终端和基站通信所使用的正常资源不可用，比如终端收到基站发出的动态SFI信令，该信令改变了正常资源的上下行属性，使得终端不能再使用该正常资源进行通信；二是潜在资源没有被占用，通常情况下，对于潜在资源，正常资源不可用的终端的优先级比较高，所以，如果基站要占用潜在资源，需要信令通知正常资源不可用的终端。
需要说明的是，正常配置的资源不可用，可能是因为这些正常配置的资源又被新的DCI调度、半静态配置等进行了重新配置，作为基站和这些终端之间的第三种资源，使得这些正常资源对本终端不可用，比如，原来的上行slot，通过动态SFI信令，变成了下行slot，那么原来终端将要传输物理上行链路共享信道(Physical Uplink Shared Channel，PUSCH)的时域资源上，终端就不能继续进行上行PUSCH的传输了。实施中，因信令导致正常资源不可用是指因动态SFI信令导致的正常资源不可用。同时，在一个时间窗内，终端没有收到基站发出的所述潜在资源被基站作为其他终端的第三种资源的消息，称为终端没有收到基站把所述潜在资源分配给其他终端作为第三资源。
具体实施中，在使用潜在资源进行传输时，如果正常资源是K个资源单位，当其中的M个正常资源不可用时，当潜在资源中有J个可用，即没有作为其他终端的第三种资源使用，则终端可以使用前面的min{M,J}个资源单位。资源单位可以是子帧subframe，时隙slot，小时隙mini-slot等。
具体实施中，所述潜在资源和所述正常资源之间是FDM；
或所述潜在资源和所述正常资源之间是TDM；
或一部分潜在资源和正常资源之间是FDM、另外一部分潜在资源和正常资源之间是TDM。
需要说明的是，FDM为频分多路复用，是一种将多路基带信号调制到不同频率载波上再进行叠加形成一个复合信号的多路复用技术；
TDM为时分多路复用，是按传输信号的时间进行分割的，它使不同的信号在不同的时间内传送，将整个传输时间分为许多时间间隔(Time Slot，TS，又称为时隙)，每个时间片被一路信号占用。
本申请实施例中，潜在资源和正常资源之间可以是频分多路复用，也可以是时分多路复用，还可以是一部分潜在资源和正常资源之间是频分多路复用，另外一部分潜在资源和正常资源之间是时分多路复用。
具体实施中，当终端确定了在潜在资源上向基站传输数据，则终端在潜在资源上与基站进行数据传输之前，终端可以通过pattern确定配置的潜在资源，其中，所述pattern是根据第一次传输占用的正常传输机会TO的位置和/或基站调整的正常资源的位置确定的。
需要说明的是，pattern为数据第一次传输占用的TO对应的资源序列。
具体的，所述pattern可以是协议规定的，也可以是基站配置给终端的。
具体实施中，在时间位置上，第一个潜在资源与第一次传输占用的正常TO之间的时间间隔大于K2，所述K2是事先约定的值。
需要说明的是，这里的第一个潜在资源与第一次传输占用的正常TO之间的时间间隔大于K2是为了避免基站在第一个潜在资源上动态调度其它的终端。
具体实施中，潜在资源与第一次传输占用的正常TO处于同一个TWG配置周期内。
需要说明的是，潜在资源与第一次传输占用的正常TO处于同一个TWG配置周期内，是为了避免造成混合是自动重传请求(Hybrid Automatic Repeat request，HARQ)过程(Process)标识号(Identity，ID)的混乱。
下面以终端与基站结合的实施流程进行说明该过程。
图2为URLLC中的数据传输方法实施流程示意图，如图所示，包括：
步骤201、基站通过DCI信令和/或RRC信令配置K个正常资源单位；
步骤202、基站通过信令或隐式配置N个潜在资源单位；
步骤203、基站与终端在正常资源上进行数据传输；
步骤204、基站通过信令改变正常资源的属性，使得部分或全部正常资源不可用；
步骤205、终端根据改变正常资源属性的信令，判断哪些正常资源不可用，停止在不可用的正常资源上的数据传输；
步骤206、终端根据收到的信令，判断潜在资源是否可用；
步骤207、终端根据不可用的正常资源和可用的潜在资源，判断出哪些潜在资源如何使用；
步骤208、基站与终端在潜在资源上进行数据传输；
步骤209、基站与终端完成整个资源周期内的数据传输。
下面再以具体实例进行说明。
实施例1
按照目前的标准，通过RRC配置，K＝4，RV＝{0 3 0 3}，时域资源位置为{起始OFDM符号，OFDM符号个数}，这个时域资源位置定义为一个传输机会TO，即完成一次重复传输的资源，K＝4意味着要进行四次重复传输，需要四个TO。这里的TO通常是连续的。
考虑用户设备(User Equipment，UE)的上行数据包在一个免调度传输(transmission without grant，TWG)配置周期内的第一个TO后、第三个TO前到达，那么UE将在第三个TO传输RV＝0的PUSCH、在第四个TO传输RV＝3的PUSCH，按照现在的标准，在本资源周期内将不再进行其他传输。基站盲检PUSCH，正常情况下，应该在第三个TO和第四个TO检测到不同RV的PUSCH。
假设该TWG配置周期内还有时间资源，基站将显式或隐式通知终端，哪些资源可以配置成为潜在的TO，潜在TO的意思是通常情况下不会被使用，仅仅在前面的正常TO不 能使用、潜在TO没有作为其他终端的第三种资源、并且基站与终端根据相同的方式确定的情况下，也就是基站和终端都能知道应该使用、知道如何使用的情况下，才能被使用。
基站配置终端，在正常的TO后面，连续N个TO为潜在资源。
基站在第三个正常TO盲检到PUSCH，则知道终端会在第一个和第二个潜在TO继续传输PUSCH，因此通常情况下基站不能在该终端的第一个和第二个潜在TO的时域位置上调用其他终端进行上行数据传输。如果基站确实想占用第一个和第二个潜在TO给其他终端进行上行数据传输，那么需要使用动态信令通知终端不能使用潜在资源，因为这些潜在资源已经作为其他终端的第三资源使用了。
通常情况下，终端在第三个正常TO传输第一个PUSCH、在第四个TO传输第二个PUSCH后，会使用第一个和第二个潜在TO传输PUSCH的RV＝0和RV＝3。
实施例2
按照目前的标准，通过RRC配置，K＝4，RV＝{0 3 0 3}，时域资源位置为{起始OFDM符号，OFDM符号个数}，这个时域资源位置定义为一个传输机会TO，即完成一次重复传输的资源，K＝4意味着要进行四次重复传输，需要四个TO。这里的TO通常是连续的。
考虑终端的上行数据包在一个TWG配置周期内的第一个正常TO传输RV＝0的PUSCH后，收到动态SFI配置信息，使得后面的若干个正常TO无法再使用，比如后两个正常TO无法使用，那么终端将在第一个正常TO、第二个正常TO传输完PUSCH后，在第三个正常TO、在第四个正常TO，按照现在的标准，在本资源周期内将不再进行传输。基站盲检PUSCH，正常情况下，应该只盲检第一个TO和第二个TO上的PUSCH。
假设该TWG配置周期内还有时间资源，基站将显式或隐式通知终端，哪些资源可以配置成为潜在的TO，潜在TO的意思是通常情况下不会被使用，仅仅在前面的正常TO不能使用、潜在TO没有作为其他终端的第三种资源、并且基站与终端根据相同的方式确定的情况下，也就是基站和终端都能知道应该使用、知道如何使用的情况下，才能被使用。
基站配置终端，在正常的TO后面，连续N个TO为潜在资源。
基站在第一个正常TO盲检到PUSCH，同时根据动态SFI信令，终端将在第一个正常TO、第二个正常TO传输完PUSCH后，在第三个正常TO、在第四个正常TO将不进行传输，同时知道终端会在第一个和第二个潜在TO继续传输PUSCH，因此通常情况下基站不能在该终端的第一个和第二个潜在TO的时域位置上调用其他终端进行上行数据传输。如果基站确实想占用第一个和第二个潜在TO给其他终端进行上行数据传输，那么需要使用动态信令通知终端不能使用潜在资源，因为这些潜在资源已经作为其他终端的第三资源使用了。
通常情况下，终端在第一个正常TO传输第一个PUSCH、在第二个TO传输第二个PUSCH后，在第三个正常TO、在第四个正常TO将不进行传输，并使用第一个和第二个潜在TO传输PUSCH的RV＝0和RV＝3。
实施例3
按照目前的标准，终端向基站传输数据时，基站通过RRC为终端配置资源，时域资源位置为{起始OFDM符号，连续的OFDM符号个数}；频域资源位置为按照类型(type)0或type1的方式分配的物理资源块(Physical Resource Block，PRB)集合。
时域资源位置和频域资源位置定义为一个传输机会TO，即完成一次重复传输，比如K＝4，RV＝{0 3 0 3}，意味着要进行4次重复传输，需要4个TO。这里的TO通常出现在连续的K个时隙上。
如果在一个TWG配置周期内有4个正常TO，终端的上行数据包在该TWG配置周期内的第一个TO后、第三个TO前到达，那么终端将通过第三个TO传输RV＝0的PUSCH、通过第四个TO传输RV＝3的PUSCH，按照现在的标准，将不再进行其他数据传输。基站盲检PUSCH，正常情况下，应该在第三个TO和第四个TO检测到不同RV的PUSCH。
假设该TWG配置周期内在第三个TO后还有时频域资源，这些时频域资源可能不同于之前配置的时频域资源，如频域位置不同，和/或时域位置不同，基站将通过显式或隐式的方式通知终端，哪些资源可以配置成为潜在资源，终端接收到基站的通知后，可以通过潜在资源进行数据传输。
其中，潜在资源的意思是通常情况下不会被使用，仅仅在前面的正常资源不能使用、并且基站和终端根据相同的方式确定需要使用的情况下，才能被使用的资源。
下面结合附图对潜在资源与正常资源之间是FDM进行说明。
如图3所示，为本申请实施例潜在资源与正常资源之间是FDM。图3中有4个正常TO，分别为TO0、TO1、TO2和TO3，有2个潜在TO，分别为Top和TOq。
从图3中可以看出，第一个潜在资源，也就是Top的时间位置出现在正常TO2之后，频域位置与正常TO的频域位置不同，也就是说潜在资源与配置资源(正常TO)是FDM的。
由于终端的上行数据包在一个TWG配置周期内的正常TO1后、正常TO2前到达，则终端通过正常TO2向基站传输数据，基站在正常TO2处盲检到PUSCH，则确定终端会通过潜在TOp和潜在TOq继续传输PUSCH。
由于终端会通过潜在TOp和潜在TOq传输数据，因此通常情况下基站不能在该终端的潜在TOp和潜在TOq的时频域资源位置上调用其他终端进行上行数据传输。如果基站 必须要占用潜在TOp和潜在TOq给其他终端进行上行数据传输，那么需要使用动态信令通知终端不能使用潜在资源进行数据传输。
通常情况下，终端在正常TO2传输第一个PUSCH、在正常TO3传输第二个PUSCH后，会使用潜在TOp和潜在TOq传输第三个PUSCH和第四个PUSCH，分别为RV＝0和RV＝3。
实施例4
按照目前的标准，终端向基站传输数据时，基站通过RRC为终端配置资源，时域资源位置为{起始OFDM符号，连续的OFDM符号个数}；频域资源位置为按照type 0或type1方式分配的PRB集合。
时域资源位置和频域资源位置定义为一个传输机会TO，即完成一次重复传输，比如K＝4，RV＝{0 0 0 0}，意味着要进行4次重复传输，需要4个TO。这里的TO通常出现在连续的K个时隙上。
如果终端的上行数据包在一个TWG配置周期内的不同时刻到达，那么终端将在不同的TO上传输第一次PUSCH，实际传输的次数与第一次传输占用的TO有关，如4图所示。
图4中，如果第一次传输占用的TO为第1个TO，则实际传输数据的次数为4次；如果第一次传输占用的TO为第2个TO，则实际传输数据的次数为3次；如果第一次传输占用的TO为第3个TO，则实际传输数据的次数为2次；如果第一次传输占用的TO为第4个TO，则实际传输数据的次数为1次。
按照现在的标准，终端向基站传输数据时，在正常TO外的其他资源上将不再进行其他传输。基站盲检PUSCH。
假设该TWG配置周期内在第一次传输占用的TO后还有可用的时频域资源，在这些时频域资源中，基站将显式或隐式通知终端哪些资源可以配置成为潜在的潜在资源，终端接收到基站的通知后，可以通过潜在资源进行数据传输。
其中，潜在资源的意思是在通常情况下不会被使用，仅仅在前面的正常资源不能使用、并且基站和终端根据相同的方式确定需要使用的情况下，才能被使用的资源。
基站为终端配置资源时，如图5所示，在一个配置周期内，基站为终端配置了4个正常TO，5个潜在TO。4个正常TO分别为TO0、TO1、TO2、TO3，5个潜在TO，分别为TOl、TOp、TOq、TOk和TOs。
当终端的上行数据包在一个TWG配置周期内的不同时刻到达时，基站首先根据第一次传输占用的TO，确定所占用的正常资源和潜在资源的时频域位置，然后遍历所有可能的第一次传输占用的TO，得到一个资源占用的pattern，该资源占用的pattern中，既包含 正常资源，又包含潜在资源，如表2所示，表2中的第二列和第三列分别为pattern 1和pattern 2。
表2
Figure PCTCN2019075937-appb-000003
在表2中，比如第一个被占用的TO为TO0，则基站确定不使用潜在资源，得到一个资源占用的pattern1为{TO0,TO1,TO2,TO3}，资源占用的pattern2为{TO0,TO1,TO2,TO3}。
在表2中，比如第一个被占用的TO为TO1，则基站确定使用一个潜在资源，得到一个资源占用的pattern1为{TO1,TO2,TO3,TOk}，资源占用的pattern2为{TO1,TO2,TO3,TOq}。
需要说明的是，表2中的TO q2、TO q3没有在图5中体现出来，可以认为TO q2和TO q3是在TO q同样时间位置上不同频域位置的TO。
表2中，还可以进一步增加其他资源占用的pattern，包括选择不同的潜在资源、不同的潜在资源排列顺序等等，都可以形成一个新的pattern。
所以，当终端的上行数据包在一个TWG配置周期内的不同时刻到达时，基站只要让终端知道用哪一个pattern即可，终端根据pattern中的TO进行数据传输。
终端知道使用哪个pattern进行数据传输，基站可以通知给终端pattern index(编号)，使终端根据pattern index确定传输数据的pattern；基站也可以固定选择一个pattern，比如表2中的pattern1，终端每次都选择pattern1进行数据传输。
实施例5
按照目前的标准，终端向基站传输数据时，基站通过RRC为终端配置资源，时域资源位置为{起始OFDM符号，连续的OFDM符号个数}，频域资源位置为按照type 0或type1的方式分配的PRB集合。
时域资源位置和频域资源位置定义为一个TO，即完成一次重复传输，比如K＝4，RV＝{0  0 0 0}，意味着要进行4次重复传输，需要4个TO。这里的TO通常出现在连续的K个时隙上。
如果终端的上行数据包在一个TWG配置周期内的不同时刻到达，那么终端将在不同的TO上传输第一次PUSCH，实际传输的次数与第一次传输占用的TO有关，如图4所示。
按照现在的标准，终端向基站传输数据时，在正常TO外的其他资源上将不再进行其他传输；如果使用潜在资源进行数据传输时，终端在第一次传输后就能知道将要使用哪些潜在资源进行数据传输。
基站在第一次传输占用的TO上盲检到PUSCH后，可以根据预先定义的pattern或者配置的潜在资源确定终端后续的传输将要使用哪些潜在资源，通常情况下基站不能调用其他终端在这些潜在资源上进行上行数据传输，以避免用户间的干扰。如果基站必须要占用终端需要使用的潜在TO给其他终端进行上行数据传输，则需要使用动态信令通知终端不能使用该潜在资源。
由于基站采用动态调度终端使用包含潜在资源的时频域资源，所以基站需要在终端第一次启用潜在资源之前的大于Kx的时间内知道终端将会启用该潜在资源，因此，在时间位置上，第一个潜在资源与第一次传输占用的正常TO之间的时间间隔必须大于Kx，以避免基站在第一个潜在资源上动态调度其他终端，这里的Kx是事先约定的值。
另外，所有潜在资源必须与第一次传输占用的正常TO处于同一个TWG配置周期内，以避免造成HARQ Process ID的混乱。
