Description

数据传输方法、装置及计算机存储介质 技术领域
本公开涉及通信技术，尤其涉及一种数据传输方法、装置及计算机存储介质。
背景技术
在第5代移动通信技术(5th generation mobile networks或5th generation wireless systems，简称5G)新空口(New Radio，NR)系统中，某些业务类型需要要求低时延，例如超高可靠低时延通信(Ultra Reliable and Low Latency Communication，URLLC)业务类型，此类业务通常要求发射端在有待传数据时能够尽快获得传输资源，减少业务在发射端缓存中等待的时延，以此降低空口传输时延。
在5G非授权频段通信系统中，发射端通常使用先监听后传输(Listen Before Talk，LBT)机制发送数据。基站和用户设备(User Equipment，UE)进行信道监听时，在频域上是以LBT band(监听频带)为单位的，而基站和UE通信所使用的频带可能较宽，能覆盖多个LBT band，基站和UE会以宽带的方式占用信道，也即基站或者UE在要发送数据，会在全部频段上对所有监听频带分别做监听，数据发送只会在LBT成功的LBT band上进行。在基站发送下行数据的过程中，如果UE有上行数据要发送，则UE需要等到基站的下行数据发送结束之后才能获得传输资源，所以上行数据的传输等待时延会增加。同理，在UE传输上行数据的过程中，如果基站有下行数据要发送，则基站需要等到UE的上行数据发送结束之后才能获得传输资源，所以下行数据的传输等待时延会增加。

在一些实施例中，终端11之间还可以建立E2E(End to End，端到端)连接。比如车联网通信(Vehicle to Everything，V2X)中的V2V(Vehicle to Vehicle，车对车)通信、V2I(Vehicle to Infrastructure，车对路边设备)通 信和V2P(Vehicle to Pedestrian，车对人)通信等场景。
在一些实施例中，上述无线通信系统还可以包含网络管理设备13。
若干个基站12分别与网络管理设备13相连。其中，网络管理设备13可以是无线通信系统中的核心网设备，比如，该网络管理设备13可以是演进的数据分组核心网(Evolved Packet Core，EPC)中的移动性管理实体(Mobility Management Entity，MME)。或者，该网络管理设备也可以是其它的核心网设备，比如服务网关(Serving Gate Way，SGW)、公用数据网网关(Public Data Network Gate Way，PGW)、策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)或者归属签约用户网络侧设备(Home Subscriber Server，HSS)等。对于网络管理设备13的实现形态，本公开实施例不做限定。
在5G NR中，某些业务类型需要要求低时延，例如超高可靠低时延通信(Ultra Reliable and Low Latency Communication，URLLC)业务类型。此类业务通常要求发射端在有待传数据时能够尽快获得传输资源，减少业务在发射端缓存中等待的时延，以此降低空口传输时延。
在5G非授权频段系统中，发射端在发送数据之前，需要先对信道进行监听，监听发现信道中的干扰低于一定的门限时，才能成功占用信道发送数据，也即使用先监听后传输(Listen Before Talk，LBT)机制。在当前的5G非授权频段通信系统中，基站和UE进行信道监听时，在频域上是以LBT band(监听频带)为单位的，一个LBT band在频域上是20MHz。基站和UE通信所使用的频带可能较宽，能覆盖多个LBT band，例如基站和UE通信使用了80MHz的非授权频段，那么该非授权频段会被分为4个LBT band。基站和UE会以宽带的方式占用信道，也即基站或者UE在要发送数据，会在全部80MHz的频段上对4个LBT band分别做监听，数据发送只会在LBT成功的LBT band上进行。
当使用非授权频段传输低时延业务时，通常用于室内的干扰环境可控 的场景。例如在室内工厂部署的控制网络，室内的游戏传感网络等。这类场景中基站和UE通信所使用的非授权频段通常受到外界的干扰比较少，干扰主要来自室内本网络中端点的干扰。对于本网络中的端点来说，如果还有空余的LBT band，那么发送端在做信道监听时，能以很大的概率监听成功并占用信道。
但如果基站在上述4个LBT band上LBT都成功了，基站会使用全部的4个LBT来发送下行数据。在基站发送下行数据的过程中，如果UE有上行数据要发送，则UE需要等到基站的下行数据发送结束之后才能可能获得传输资源，所以上行数据的传输等待时延会增加。同样的道理，如果UE占用了4个LBT来传输上行数据，那么如果基站有下行数据要发送，则基站需要等到UE的上行数据发送结束之后才能可能获得传输资源，所以下行数据的传输等待时延会增加。
基于上述无线通信系统，如何在非授权频段上降低数据传输的时延，提出本公开方法各个实施例。
图2是根据一示例性实施例示出的一种数据传输方法的流程图一，如图2所示，该数据传输方法用于基站中，包括以下步骤：
在步骤S11中，确定非授权频段内的一个或一个以上的监听频带；
在步骤S12中，确定所述一个或一个以上的监听频带中至少一个监听频带的频带类型；其中，所述频带类型包括以下的至少一种：上行监听频带，或下行监听频带，或未限定监听频带；其中，所述下行监听频带用于下行传输；所述上行监听频带用于上行传输；所述未限定监听频带既能用于进行上行传输也能用于进行下行传输。
如此，由于确定了非授权频段上至少一个监听频带的频带类型，至少能降低上行数据或下行数据的传输等待时延，从而有助于在非授权频段上降低上行数据或下行数据传输的时延。
在一些实施例中，步骤S12，包括：
确定所述一个或一个以上的监听频带中至少一个监听频带的频带类型为上行监听频带；其中，所述上行监听频带用于上行传输。
如此，由于确定了非授权频段上至少一个频带类型为上行监听频带，进而保证在有上行数据需要发送时有用于上行传输的监听频带可用，不会出现有上行数据要发送但需要等到下行数据发送结束之后才能获得传输资源的情况，能减少上行数据的传输等待时延，从而降低上行数据传输的时延。
在一些实施例中，步骤S12，包括：
确定所述一个或一个以上的监听频带中至少一个监听频带的频带类型为下行监听频带；其中，所述下行监听频带用于下行传输。
如此，由于确定了非授权频段上至少一个频带类型为下行监听频带，进而保证在有下行数据需要发送时有用于下行传输的监听频带可用，不会出现有下行数据要发送但需要等到上行数据发送结束之后才能获得传输资源的情况，能减少下行数据的传输等待时延，从而降低下行数据传输的时延。
在一些实施例中，步骤S12，包括：
确定所述一个或一个以上的监听频带中至少一个监听频带的频带类型为上行监听频带，所述上行监听频带用于上行传输；以及
确定所述一个或一个以上的监听频带中至少一个监听频带的频带类型为下行监听频带，所述下行监听频带用于下行传输。
如此，由于确定了非授权频段上至少一个频带类型为下行监听频带的监听频带，和至少一个频带类型为上行监听频带的监听频带，进而不会出现有上行数据要发送但需要等到下行数据发送结束之后才能获得传输资源的情况，减少上行数据的传输等待时延，降低上行数据传输的时延；也不会出现有下行数据要发送但需要等到上行数据发送结束之后才能获得传输资源的情况，减少下行数据的传输等待时延，降低下行数据传输的时延。
在一些实施例中，所述方法还包括：
向UE发送监听频带配置信息，所述监听频带配置信息中包括频带类型指示信息，所述频带类型指示信息用于指示所述非授权频段内的一个或一个以上的监听频带的类型。
如此，能够通知UE非授权频段内的一个或一个以上的监听频带的类型，便于UE基于基站配置的监听频带的类型，选择对应的监听频带进行对应的工作。比如，选择类型为下行监听频带的监听频带监听下行信息；选择类型为上行监听频带的监听频带传输上行信息。
在一些实施方式中，所述向UE发送监听频带配置信息，包括：
通过广播消息向所述UE发送监听频带配置信息。
如此，可通过广播消息向UE发送监听频带配置信息，告知UE监听频带配置信息，通过广播消息这类已有信令来指示监听频带配置信息，能节省信令个数。
在一些实施方式中，所述向UE发送监听频带配置信息，包括：
通过RRC层信令向所述UE发送监听频带配置信息。
如此，可通过RRC层信令向UE发送监听频带配置信息，告知UE监听频带配置信息，这样，通过RRC信令能够为不同的UE配置不同的上行和下行监听频带，因而能使得各个监听频带上负载均衡。
当然，在本公开的一些实施方式中，可以用任何已有的或是新增的信令来发送该频带配置信息，本公开实施方式中并不对此做出限定。
在一些实施方式中，所述确定所述一个或一个以上的监听频带中至少一个监听频带的频带类型，包括：
通过协议约定方式确定所述一个或一个以上的监听频带中至少一个监听频带的频带类型。
比如，当非授权通信频段包含多个监听频带时，通过协议约定特定的1个或者多个监听频带的频带类型为上行监听频带、或下行监听频带、或未 限定监听频带。例如，可以在协议中约定多个监听频带中，频率最低的监听频带为上行监听频带，频率最高的监听频带为下行监听频带。
在一些实施例中，频带类型为上行监听频带的监听频带的频率，低于频带类型为下行监听频带的监听频带的频率。
如此，由于频率较低的频带传播损耗更小，由于终端的发送功率相对于基站来说要小，因而使用较低频率的上行监听频带有利于增强上行覆盖范围，使得上下行覆盖范围的平衡。
在一些实施例中，确定所述一个或一个以上的监听频带中至少一个监听频带的频带类型，包括：
当与UE通过非授权频段通信，且通信所使用的非授权频段包括两个或两个以上的监听频带时，为至少一个所述监听频带确定频带类型；其中，所述频带类型为所述下行监听频带或所述上行监听频带的个数，小于所述非授权频段包括的监听频带的总个数。
如此，能够保证非授权频段内的监听频段中，既有用于传输上行信息的监听频带，又有用于传输下行信息的监听频带，从而有助于降低数据传输的时延。
在一些实施例中，所述确定所述一个或一个以上的监听频带中至少一个监听频带的频带类型，包括：
接收到UE发送的调度请求时，确定所述一个或一个以上的监听频带中至少一个监听频带的频带类型为所述上行监听频带。
如此，能够为UE配置用于传输上行信息的监听频带，由于基站将不在该频带类型为上行监听频带的监听频带上发送下行信息，包括下行控制信息和下行数据信息，因此，能够保证UE在有上行数据需要发送时有用于上行传输的监听频带可用，不会出现有上行数据要发送但需要等到下行数据发送结束之后才能获得传输资源的情况，能减少上行数据的传输等待时延，从而降低上行数据传输的时延。
在一些实施例中，所述确定所述一个或一个以上的监听频带中至少一个监听频带的频带类型，包括：
为UE配置用于周期性传输PUSCH信息的资源时，确定所述一个或一个以上的监听频带中至少一个监听频带的频带类型为所述上行监听频带。
如此，能够为UE配置用于传输上行信息的监听频带，便于UE自发的传输上行信令或数据。例如，UE利用该频带类型为上行监听频带的监听频带传输CG-PUSCH信息。其中，CG-PUSCH,Configured grant-PUSCH，中文含义为配置授权的PUSCH，有时也叫做上行免授权(UL grant free)PUSCH。

图3是根据一示例性实施例示出的一种数据传输方法的流程图二，如图3所示，该数据传输方法用于用户终端(UE)中，包括以下步骤：
在步骤S21中，确定非授权频段内的一个或一个以上的监听频带；
在步骤S22中，在非授权频段内的一个或一个以上的监听频带中，确定至少一个监听频带的频带类型；其中，所述频带类型包括以下的至少一种：上行监听频带，或下行监听频带，或未限定监听频带；其中，所述下行监听频带用于下行传输；所述上行监听频带用于上行传输；所述未限定监听频带既能用于进行上行传输也能用于进行下行传输。
如此，由于确定了非授权频段上至少一个监听频带的频带类型，至少 能降低上行数据或下行数据的传输等待时延，从而有助于在非授权频段上降低数据传输的时延。
上述方案中，所述确定至少一个监听频带的频带类型之前，所述方法还包括：
获取基站发送的监听频带配置信息，所述监听频带配置信息中包括频带类型指示信息，所述频带类型指示信息用于指示非授权频段内的一个或一个以上的监听频带的类型。
如此，便于UE根据监听频带配置信息确定非授权频段内的一个或一个以上的监听频带的类型，进而便于UE基于基站配置的监听频带的类型，选择对应的监听频带进行对应的工作。比如，选择类型为下行监听频带的监听频带监听下行信息；选择类型为上行监听频带的监听频带传输上行信息。
在一些实施例中，所述获取监听频带配置信息，包括：
