随着通信技术的发展，第五代(5th-Generation，5G)技术应运而生，各个通信主流公司都致力于5G技术的研发，目的之一是将5G技术运用于低时延高可靠物联网(Ultra-Reliable Low Latency Communicatinon，URLLC)的应用场景。其中，所谓低时延高可靠通信是指端到端时延为毫秒级并且传输可靠性接近100％，从而可支持车联网，智能制造和工业互联网等诸多应用场景。
现有技术下，为进行上行数据的传输，基站对终端进行资源分配主要采用以下几种方式：
第一种方式为：终端通过物理上行链路控制信道(Physical Uplink Control CHannel，PUCCH)向基站发送包含上行调度请求(Scheduling Request，SR)的控制信息，然后，基站根据接收的SR向终端发送上行调度授权(UL grant)，并给终端分配少量的资源，进一步地，终端向基站上报缓存状态报告(Buffer Status Report，BSR)后，基站根据获取终端的探测参考信号(Sounding RS，SRS)以及自身的现有资源，对终端进行物理上行共享信道(Physical Uplink Shared CHannel，PUSCH)资源分配，并且所有终端的上行时频资源是正交的，不存在上行资源冲突的问题。
然而，终端在每次进行上行数据传输时，若没有PUSCH资源，则需要通过SR进行申请。其中，一个数据收发周期需要10.5个传输时间间隔(transmission time interval，TTI)，TTI取值为0.125ms，即一个数据收发周期为1.3125ms，重传时总时延则为17.5个TTI。
此外，数据成功传输依赖于SR、物理下行控制信道(Physical Downlink Control CHannel，PDCCH)和PUSCH的正确接收，若要求数据块误码率(Block Error Ratio，BLER)为10e-5，则要求每一个信道的BLER都低于10e-5，而SR、PDCCH和PUSCH都难以满足。
可见，采用第一种方式，缺点在于，难以满足URLLC业务空口时延1ms时延要求， 以及可靠性要求，影响了用户速率感知；优点在于，所有终端的上行时频资源是正交的，不存在上行资源冲突的问题。
第二种方式为：上行免调度传输，即不需要发送SR申请以及等待基站进行调度，基站接收数据后直接发出，但需要预配置终端用于上行免调度传输的资源或资源池。其中，终端的上行免调度资源可以是专用的，也可以是共享的。
终端采用上行免调度传输时，进行上行数据传输的一个完整的收发周期为3个TTI，重传时则总时延为10个TTI，设置初始BLER为1％，则平均时延为3*99％TTI+10*1％TTI＝3.07TTI，低于0.5ms。
可见，采用第二种方式，优点在于，一次数据传输以及重传平均时延都低于0.5ms，满足URLLC的低时延要求，并且时延降低使相同的时延要求下可以支持更多的重传，从而提高了可靠性；缺点在于，当上行免调度传输资源为终端间共享并且多个终端选择相同的资源进行上行数据传输时，则会发生碰撞，降低了传输速率。

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，并不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做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。
为了在进行数据传输时，降低时延，避免发生碰撞，提高传输速率以及可靠性，本发明实施例中，设计了一种免调度传输的方法，该方法为，基于业务交互状态，确定业务负荷低时，对终端进行专用资源分配，确定业务负荷高时，对终端进行共享资源分配，以及基于采用分配的资源进行数据传输的传输结果，向终端发送应答信息。
下面结合附图对本申请优选的实施方式进行详细说明。
参阅图1所示，本发明实施例中，对免调度传输的具体流程如下：
步骤100：基站监测业务交互状态，获得业务需求评估结果。
具体的，首先，基站按照预设的周期，获取业务交互状态信息，其中，交互状态信息至少包含本地与已接入的各个终端之间的业务交互量，终端的业务类型，以及终端的优先级。
这样，基站就可以对本地与已接入的终端之间的业务交互状态，如，业务交互量，进行实时监测以及记录。
然后，基站基于交互状态信息包含的本地与每一个已接入的终端之间的业务交互量的加和，获得总业务交互量。
这样，基站就可以根据当前的总业务交互量，对终端进行后续的资源分配。
进一步地，若总业务交互量高于预设交互门限值，并且终端的业务类型为非周期性业务，以及终端的优先级低于预设优先级门限，则获得表征业务需求负荷高的业务需求评估结果，否则，获得表征业务负荷低的业务需求评估结果。
例如，基站确定终端的业务类型为周期性URLLC业务，则获得表征业务负荷低的业务需求评估结果。
又例如，基站确定终端的优先级高于预设优先级门限，则获得表征业务负荷低的业务需求评估结果。
又例如，基站确定总业务交互量低于预设交互门限值，则获得表征业务负荷低的业务 需求评估结果。
又例如，基站确定总业务交互量高于预设交互门限值，终端的业务类型为非周期性URLLC业务，并且优先级低于预设优先级门限，则获得表征业务负荷高的业务需求评估结果。
这样，基站就可以通过与终端之间的业务交互状态，确定总的业务交互量，以及终端的业务类型以及优先级，从而对终端的业务负荷状况进行评估，为后续进行资源分配做好准备。
步骤110：基站判断业务需求评估结果是否表征业务负荷低，若是，执行步骤120，否则，执行步骤130。
步骤120：基站对终端进行专用资源分配。
具体的，基站对业务需求评估结果表征负荷低的终端，进行专用资源分配。
例如，参阅图2所示，基站分别为终端1，终端2，终端3以及终端4分配了相应的专用资源。各个终端分配的专用资源对应的频率均不相同，避免了资源冲突。
这样，基站就可以对优先级高的终端进行专用资源分配，并对业务类型为周期性URLLC业务的终端进行专用资源分配，以及在总业务交互量较低时，对各个终端进行专用资源分配，完全避免了资源冲突，提高了数据传输的可靠性。
步骤130：基站对终端进行共享资源分配。
具体的，终端对业务需求评估结果表征负荷高的终端，进行共享资源分配。
首先，基站获取已经获得共享资源的各个终端的业务信息，如频率，业务速率等，并确定待分配的终端的业务信息，以及根据所有终端的业务信息，为待分配的终端选择合适的共享终端。
例如，参阅图3所示，基站确定终端1和终端2的频率处于同一频段，则将终端1和终端2分配同一个共享资源，终端3和终端4处于同一频段，则将终端3和终端4分配同一个共享资源，终端5至终端8处于同一频段，则将终端5至终端8分配同一个共享资源。由于终端较多，则将终端9至终端14分配同一个共享资源，并且与终端1至终端8对应的共享时间段不同，从而避免资源冲突。
这样，就可以根据终端的频率，业务速率等业务信息，选择合适的共享资源，以避免资源冲突。
步骤140：基站获取终端基于分配的资源进行数据传输的传输结果。
步骤150：基站基于传输结果，按照预设的动态应答规则，向终端发送应答信息。
具体的，首先，基站获取终端的应答配置信息。
然后，基站判断应答配置信息是否表征标准应答，若是，则基站直接向终端发送应答信息，终端接收应答信息后，遵循默认流程处理，其中，应答信息中至少包含传输结果和 终端标识信息，否则，基站通过物理下行控制信道向终端发送应答信息，终端将会在某一段时间内在物理下行控制信道内获取应答信息，并按照应答信息中包含的通知指示进行处理，其中，应答信息中至少包含传输结果，终端标识信息以及资源复用信息。
例如，基站确定终端的应答配置信息表征标准应答，则直接向终端发送应答信息。
又例如，基站确定终端的应答配置信息表征非标准应答，则通过物理下行控制信道向终端发送应答信息。
这样，终端就可以根据是否收到应答信息，判断与基站之间传输的数据是否被正确接收。
步骤160：基站接收终端的重传请求消息，重新为终端分配重传资源。
具体的，首先，终端确定在指定的时间内未收到基站发送的应答信息时，向基站发送重传请求消息。
然后，基站重新为终端分配重传资源，可以采用但不限于以下几种方式：
第一种方式为：基于接收的终端的重传请求消息中包含的重传优先级，确定重传优先级高于预设重传优先级门限时，按照随机选择的方式，进行专用重传资源配置。
第二种方式为：基于接收的终端的重传请求消息中包含的重传优先级，确定重传优先级高于重传优先级门限时，按照预设的重传资源配置方式，进行专用重传资源配置。
第三种方式为：基于接收的终端的重传请求消息中包含的重传优先级，确定重传优先级低于重传优先级门限时，按照随机选择的方式，进行标准重传资源配置。
第四种方式为：基于接收的终端的重传请求消息中包含的重传优先级，确定重传优先级低于重传优先级门限时，按照预设的重传资源配置方式，进行标准重传资源配置。
这样，基站就可以为重传优先级高的终端进行专用重传资源配置，为重传优先级低的终端进行标准重传资源配置，提高重传优先级高的终端的数据传输的成功率，以及通过随机选择的方式，或者预设的重传资源配置方式进行资源配置，减少了发生资源冲突的概率，进一步提高了数据传输的可靠性。
进一步地，基站基于接收的终端的重传请求消息包含的重传时间，按照随机分配的方式，为终端分配重传时长范围，并在重传时长范围内，随机选择延迟时长，其中，延迟时长用于设置与终端传输重传数据的时间点。
最后，终端基于分配的重传资源，按照选择的延迟时长向基站发送数据。
例如，假设，终端1的重传优先级高于预设的重传优先级门限，则基站按照随机选择的方式，为终端分配专用重传资源。然后，基站为终端1分配的重传时长范围为(0.5ms，0.7ms)，并在重传时长范围内随机选择延迟时长为0.6ms。进一步地，终端基于分配的专用重传资源，按照延迟时长0.6ms向基站发送重传数据。
下面采用一个具体的应用场景，对上述实施例进行进一步地说明：
首先，基站按照预设的周期，获取基站与已经接入的各个终端的业务交互量，以及终端1的业务类型和优先级。
然后，基站基于与已接入的各个终端的业务交互量的加和，确定总业务交互量高于预设交互门限值。
接着，基站确定终端1的业务类型为非周期性URLLC业务，并且优先级高于预设优先级门限，获得表征业务负荷高的业务需求评估结果。
然后，基站确定共享资源Ma对应的终端2的频率为a，对应的终端3的频率为b，终端1的频率为c，其中，a，b，以及c均处于同一个频段，则为终端1分配共享资源Ma。
接着，终端1基于分配的共享资源Ma，向基站发送传输数据后，基站基于终端的表征标准应答的应答配置信息，直接向终端发送包含传输结果和终端标识信息的应答信息。
进一步地，终端在指定的时间5s内，没有收到应答信息，则向基站发送重传请求信息。基站确定接收的重传请求信息中包含的重传优先级高于预设重传优先级门限，按照随机选择的方式，进行专用重传资源配置，以及基于重传请求消息包含的重传时间，按照随机分配的方式，为终端分配重传时长范围(0.4ms，0.6ms)，并在重传时长范围内，随机选择延迟时长0.5ms.
最后，终端基于分配的专用重传资源，按照延迟时长0.5ms向基站发送重传数据。
