技术领域
本公开涉及通信技术领域，具体涉及一种数据传输方法、基站和用户终端。
背景技术
未来5G(第五代移动通信系统)需要适应更加多样化的场景和业务需求。NR(New Radio，新无线)的主要场景包括eMBB(Enhance Mobile Broadband，增强型移动宽带)、mMTC((massive machine type of communication)海量机器类通信)、超高可靠超低时延通信URLLC(Ultra-reliableand low latency communications，低时延高可靠通信)，这些场景对系统提出了高可靠、低时延、大带宽、广覆盖等要求。对于某些场景的业务，要求低延时和高可靠的传输。针对这样的业务需求，NR支持免授权传输(grant-free)方式，减少信令交互流程，保证低时延要求。
NR系统中，UL(UpLink，上行链路)grant-free传输支持半静态的资源配置，为进行UL grant-free的可能的UE预留资源。由于grant-free的传输方式可用于低时延的业务，为了保证低时延的业务需求，半静态配置的grant-free资源在时间上需要保证一定的密度，才能满足对时延敏感的业务需求。而如果预留较多的资源，会占用正常业务能够使用的时频资源，造成资源的利用率下降。
NR讨论grant-free传输可以在共享的资源下进行。因此可考虑为不同的UE(User Equipment，用户终端)分配相同资源来提供资源的利用率，但是这种方式会带来传输碰撞的问题。
然而，还没有有效的机制能够对资源碰撞问题进行很好的处理。

如图5所示，基站为UE配置多个免授权传输的资源配置，包括Grant-free资源配置1和Grant-free资源配置2，Grant-free资源配置1和Grant-free资源配置2之间具有如下关系：时频资源的大小和位置相同，其他配置参数(如：RS参数、MCS、repetition方式、RV版本或者发射功率等)均相同，传输间隔不同，Grant-free资源配置1的传输间隔是T1，Grant-free资源配置2的传输间隔是T2。Grant-free资源配置1的资源块的大小和Grant-free资源配置2的资源块大小均为F1。
如果业务1是时延敏感业务，业务2是对时延要求不高的业务，UE根据业务的性能指标，UE可选择Grant-free资源配置2用于业务1数据的传输，选择Grant-free资源配置1用于业务2数据的传输。
如图6，基站为UE配置多个免授权传输的资源配置，包括Grant-free资源配置1和Grant-free资源配置2，Grant-free资源配置1和Grant-free资源配置2之间具有如下关系：时频资源的大小和位置相同，其他配置参数(如RS 参数、MCS、repetition方式、RV版本)均相同，传输间隔和发射功率不同。Grant-free资源配置1的传输间隔为T1，发射功率为P1，Grant-free资源配置2的传输间隔为T2，发射功率为P2。Grant-free资源配置1的资源块的大小和Grant-free资源配置2的资源块大小均为F1。
参见图7，基站为UE配置多个免授权传输的资源配置，包括：Grant-free资源配置1和Grant-free资源配置2，Grant-free资源配置1和Grant-free资源配置2之间具有如下关系：部分配置参数(如RS参数、MCS、repetition方式、RV版本、发射功率或传输间隔等)均相同，时频资源的大小不同，时频资源的频域相互正交，Grant-free资源配置1和Grant-free资源配置2的传输间隔均为T1。Grant-free资源配置1的资源块的大小为F1，Grant-free资源配置2的资源块大小为F2，F1>F2，Grant-free资源配置1的资源块与Grant-free资源配置2的资源块在频域相互正交。
UE根据业务的数据量或负载大小选择相应的免授权传输的资源配置，如业务1的数据块较大，业务2的数据块较小，则UE可选择Grant-free资源配置1用于业务1数据的传输，选择Grant-free资源配置2用于业务2数据的传输。
参见图8，基站给UE配置多个免授权传输的资源配置，包括：Grant-free资源配置1和Grant-free资源配置2，Grant-free资源配置1和Grant-free资源配置2之间具有如下关系：部分配置参数(如RS参数、MCS、repetition方式、RV版本、传输间隔或者发射功率等)均相同，时频资源的大小不同，时频资源的时域上相互正交，Grant-free资源配置1和Grant-free资源配置2的传输间隔均为T1。
参见图9，基站给UE配置多个免授权传输的资源配置，包括：Grant-free资源配置1和Grant-free资源配置2，Grant-free资源配置1和Grant-free资源配置2之间具有如下关系：部分配置参数(如RS参数、MCS、repetition方式、RV版本、传输间隔或者发射功率等)均相同，时频资源的大小相同，时频资源通过正交码(如OCC1用于Grant-free资源配置1，OCC2用于Grant-free资源配置2)进行码分复用，在码域上相互正交，Grant-free资源配置1和Grant-free资源配置2的传输间隔均为T。其中，OCC(Orthogonal cover code)中文含义为：正交覆盖编码。
参见图10，基站为UE配置多个免授权传输的资源配置，包括Grant-free资源配置1和Grant-free资源配置2，Grant-free资源配置1和Grant-free资源配置2之间具有如下关系：部分配置参数(如RS参数、MCS、repetition方式、RV版本、传输间隔或者发射功率等)均相同，时频资源的大小不同，时频资源的位置如图10所示，其中Grant-free资源配置1的资源块大小为F1，Grant-free资源配置2的资源块大小为F2，F1>F2，Grant-free资源配置1的资源块与Grant-free资源配置2的资源块在时频位置上部分重叠。Grant-free资源配置1和Grant-free资源配置2的传输间隔均为T1。
UE根据业务的数据量或负载大小选择相应的免授权传输的资源配置进行上行数据传输。如业务1的数据块较大，业务2的数据块较小，则UE可选择Grant-free资源配置1用于业务1数据的传输，选择Grant-free资源配置2用于业务2数据的传输。基站可为不同的UE在不同的频域位置上，配置频域带宽为F2的免授权传输的资源配置，这样可降低不同UE在传输块较小时的碰撞概率。
参见图11，基站为UE配置多个免授权传输的资源配置，包括Grant-free资源配置1和Grant-free资源配置2，Grant-free资源配置1和Grant-free资源配置2之间具有如下关系：部分配置参数(如RS参数、MCS、repetition方式、RV版本、或者发射功率等)均相同，时频资源的大小不同，时频资源的位置如图11所示，其中Grant-free资源配置1的资源块大小为F1，Grant-free资源配置2的资源块大小为F2，F1>F2，Grant-free资源配置1的资源块与Grant-free资源配置2的资源块在时频位置上部分重叠；Grant-free资源配置1和Grant-free资源配置2的传输间隔不同，Grant-free资源配置1的传输间隔为T1，Grant-free资源配置2的传输间隔为T2。传输间隔大的授权传输的资源配置，分配资源数量较多，可以一定程度提高资源的利用率。
参见图12，基站为UE配置多个免授权传输的资源配置时，可以分配不同的时频资源的大小。为了降低基站检测的复杂度，对于某种时频资源的大小的免授权传输的资源配置，其时频资源的起始位置有所限制，如可限制起始位置与时频资源编号是有关系的。例如：如图12所示，UE1配置了三种免授权传输的资源配置，Grant-free资源配置1-1、Grant-free资源配置1-2、Grant-free资源配置1-3，资源块的大小分别为L＝1，L＝2和L＝4；其中较小 的资源块为较大的资源块的子集，例如Grant-free资源配置1-1的资源块是Grant-free资源配置1-2的资源块的子集，Grant-free资源配置1-2的资源块是Grant-free资源配置1-3的资源块的子集。
同样，UE2配置了三种免授权传输的资源配置，Grant-free资源配置2-1、Grant-free资源配置2-2、Grant-free资源配置2-3，资源块的大小分别为L＝1，L＝2和L＝4；其中较小的资源块为较大的资源块的子集，例如Grant-free资源配置2-1的资源块是Grant-free资源配置2-2的资源块的子集，Grant-free资源配置2-2的资源块是Grant-free资源配置2-3的资源块的子集。
基站可为不同UE配置不同的较小时频资源的免授权传输的资源配置，如图12所示，UE2的Grant-free资源配置2-1和grant-free资源配置2-2分别与UE1的Grant-free资源配置1-1和Grant-free资源配置1-2相互正交。
参见图13，基站可通过动态信令(L1或L2控制信令)对每个免授权传输的资源配置(包括Grant-free资源配置1和Grant-free资源配置2)进行激活/去激活，UE通过获取基站的指示在激活的一个或多个免授权传输的资源配置中选择相应的配置参数进行上行数据传输，基站只需要在激活的免授权传输的资源配置上依据相应的配置参数进行上行传输的盲检。
例如，如图13所示，基站通过L1或者L2控制信令去激活Grant-free资源配置1，保持Grant-free资源配置2处于激活状态，以适应接下来的低时延业务，减少基站盲检的复杂度。其中，Grant-free资源配置1的资源块大小为F1，Grant-free资源配置2的资源块大小为F2，F1>F2，Grant-free资源配置1的资源块与Grant-free资源配置2的资源块在时频位置上部分重叠。Grant-free资源配置1的传输间隔为T1，Grant-free资源配置2的传输间隔为T2。
