Description

数据的传输方法、装置、设备及计算机可读存储介质 技术领域
本申请涉及无线通信技术领域，具体而言，本申请涉及一种数据的传输方法、装置、设备及计算机可读存储介质。
背景技术
现有技术中先听后说的信道接入机制(LBT，Listen Before Talk)不能解决非授权频谱通信中的隐藏节点问题。如图1所示，TX1将要给RX1发送数据，发送之前，TX1做空闲信道检测(CCA，Clear Channel Assessment)。而此时TX2正在给RX2发送数据，其发送的信号将对RX1的接收造成干扰，但是由于TX1距离TX2较远，在CCA时将检测不到来自TX2的干扰，所以TX1将占用信道向RX1发送数据。此种情况下，RX1的数据接收受到来自TX2的强干扰。对于TX1来说，TX2就是隐藏节点。
为了解决隐藏节点问题，在目前已有的一种技术方案中，在NR-U(NR-Unlicensed，基于新空口的非授权频谱)中引入一种新的空中接口信号，信道作用指示(CUI，Channel Usage Indication)信号，其作用类似802.11中的RTS(Request to Send，请求发送帧)/CTS(Clear to Send，信道清除帧)信号。发送端经过LBT过程占用信道之后，向接收端发出CUI-T(Channel Usage Indication for Transmission，用于发送的信道作用指示)信号，用于表示在接下来的数据传输过程中将作为发送端占用信道。接收端在收到CUI-T信号，将发出CUI-R(Channel Usage Indication for Reception，用于接收的信道作用指示)信号，用于表示在接下来的数据传输过程中将作为接收端占用信道。若周围的其他要发送数据的节点监听到用于发送的信道作用指示信号CUI-T信号，则不进行退避；相反，若监听到用于接收的信道作用指示信号CUI-R信号，则进行退避。
现有技术中的解决隐藏节点的办法，需要发送端在经过LBT过程占 据信道以后，与接收端进行CUI-T/CUI-R进行握手之后才能开始数据传输，浪费了部分传输资源。

具体实施方式
为使得本申请的发明目的、特征、优点能够更加的明显和易懂，下面将结合本申请实施例中的附图，对本申请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申请一部分实施例，而非全部实施例。基于本申请中的实施例，本领域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，都属于本申请保护的范围。
下面详细描述本申请的实施例，该实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本申请，而不能解释为对本申请的限制。
本技术领域技术人员可以理解，除非特意声明，这里使用的单数形式“一”、“一个”、“所述”和“该”也可包括复数形式。应该进一步理解的是，本申请的说明书中使用的措辞“包括”是指存在特征、整数、步骤、操作、元件和/或组件，但是并不排除存在或添加一个或多个其他特征、整数、步骤、操作、元件、组件和/或它们的组。应该理解，当我们称元件被“连接”或“耦接”到另一元件时，它可以直接连接或耦接到其他元件，或者也可以存在中间元件。此外，这里使用的“连接”或“耦接”可以包括无线连接或无线耦接。这里使用的措辞“和/或”包括一个或更多个相关联的列出项的全部或任一单元和全部组合。
为了更好的理解及说明本申请实施例的方案，下面对本申请实施例中所涉及到的一些技术进行简单说明。
在R16 NR-U(NR-Unlicensed，基于新空口的非授权频谱)的标准讨论和设计中，发送端在发送数据之前，通常要进行空闲信道检测(CCA，Clear Channel Assessment)，用来评估信道中的干扰水平。如果干扰低于能量检测门限(该门限由通信协议所规定)，则发送端认为信道空闲，发 送端可以占用信道发送数据。如果干扰水平高于检测门限，则发送端认为信道繁忙，发送端将不能占用信道发送数据。这就是先听后说的信道接入机制(LBT，Listen Before Talk)。
在5G(5th-Generation，第五代移动通信技术)系统中有一类要求高可靠性和低时延的业务类型，即URLLC(Ultra-reliable and Low Latency Communications，超高可靠与低时延通信)业务，还有一类相比较而言，并不要求那么高的可靠性和低时延，但会要求较大的数据传输速率，也即eMBB(Enhanced Mobile Broadband，增强移动宽带)业务。
对于同一个UE来说，同时有URLLC业务和eMBB业务是一种常见的场景。为了支持两种业务的灵活复用，在R16的URLLC讨论中，已经确定了对于PUSCH(无论是动态调度的，还是半静态配置的)要在物理层能区分优先级。半静态配置的PUSCH(Physical Uplink Shared Channel，物理上行共享信道)是通过RRC(Radio Resource Control，无线资源控制)配置参数直接配置优先级，动态调度的PUSCH是通过物理层指示来指示优先级，例如，使用DCI(Downlink Control Information，下行控制信息)中的1bit来指示优先级。URLLC上行业务通常应该使用高优先级的PUSCH来调度。
在R17标准讨论中，将研究如何在非授权频段上部署URLLC业务。当URLLC业务部署在非授权频段上时，为了支持与eMBB业务的灵活复用，应该同样支持2种不同优先级的PUSCH调度。对于URLLC上行业务，可以使用高优先级的PUSCH来传输，对于eMBB上行业务，可以使用低优先级的PUSCH来传输。
下面以具体的实施例对本申请的技术方案以及本申请的技术方案如何解决上述技术问题进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。下面将结合附图，对本申请的实施例进行描述。
本申请实施例描述的网络架构以及业务场景是为了更加清楚地说明本申请实施例的技术方案，并不构成对本申请实施例提供的技术方案的限 定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
本申请实施例提供的一种网络架构的示意图如图2所示，该网络架构包括：基站110、UE120和多个节点130。基站110部署在接入网中。例如，基站110部署在5G系统中的接入网NG-RAN(New Generation-Radio Access Network，新一代无线接入网)。基站110与UE120之间或基站110与多个节点130之间通过某种空口技术互相通信，例如可以通过蜂窝技术相互通信。
本申请实施例中提供了一种数据的传输方法，应用于基站，该方法的流程示意图如图3所示，该方法包括：
S101，在上行传输开始之前发送信道占用指示，信道占用指示用于指示基站的相邻节点不发送数据。
在一种实现的方式中，基站是非授权频谱小区的基站，非授权频谱小区是指允许UE使用非授权频段(或称为非授权频谱)与基站进行通信的小区。
在一种实现的方式中，基站的类型包括各种形式的宏基站、微基站、中继站、接入点等。
在一种实现的方式中，信道占用指示，包括以下至少一项：
上行传输的起始位置；上行传输的时长信息；基站的标识。
在一种实现的方式中，信道占用指示可以携带上行传输的起始位置和上行传输的时长信息，用于通知基站的相邻节点进行退避的具体时段，即基站通知基站的相邻节点在该具体时段内不发送数据。
在一种实现的方式中，信道占用指示可以携带基站的标识ID，例如，物理小区ID，物理小区ID用于表示该信道占用指示的来源。作为发送端的UE可以将该信道占用指示作为基站的反馈信息。当UE接收到基站发送的信道占用指示，则UE确定基站的接收干扰较小，UE可以向基站发送上行数据；当UE没有接收到基站发送的信道占用指示，则UE确定基站的接收干扰较大，UE将不向基站发送上行数据。
在一种实现的方式中，相邻节点包括除基站和UE之外的发送端。
在一种实现的方式中，相邻节点的类型包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备，以及各种形式的基站、用户设备(User Equipment，UE)、移动台(Mobile Station，MS)、终端设备(terminal device)等。
S102，接收用户设备UE发送的上行数据。
本申请实施例中，基站在上行传输开始之前发送信道占用指示，信道占用指示用于指示基站的相邻节点不发送数据；接收用户设备UE发送的上行数据。如此，实现了基站在UE的上行数据的传输开始之前就发送信道占用指示，指示基站的相邻节点进行退避，即指示基站的相邻节点不发送数据，指示UE进行上行数据的传输，使UE在占用信道后，不需要向基站发送信道占用指示，UE就可以直接开始进行上行数据的传输，从而解决了各隐藏节点干扰的问题，且能够节省传输资源。
在一种实现的方式中，在发送信道占用指示之前，还包括：
进行空闲信道检测，确定干扰值；
当干扰值小于预设的能量检测阈值，确定发送信道占用指示；
当干扰值不小于预设的能量检测阈值，确定不发送信道占用指示。
在一种实现的方式中，基站在UE开始进行上行数据发送之前，基站进行空闲信道检测，确定干扰值；当干扰值小于预设的能量检测阈值，基站检测到其周围的信道空闲，则基站发送信道占用指示给UE和基站的相邻节点，基站的相邻节点接收到该信道占用指示后，进行退避，即相邻节点不发送数据；当干扰值不小于预设的能量检测阈值，基站检测到其周围的信道繁忙，即相邻节点正在发送数据，正在发送数据的相邻节点为隐藏节点，则基站不发送信道占用指示给UE和相邻节点。能量检测阈值，即能量检测的门限，可以由通信协议约定或者基站自行定义。相邻节点包括除基站和UE之外的发送端。
在一种实现的方式中，在发送信道占用指示之前，还包括：
向UE发送DCI调度指令，以用于使UE在DCI调度指令指示的第一时频资源的位置上进行上行数据的传输，第一时频资源包括物理上行共享信道PUSCH。
在一种实现的方式中，在发送信道占用指示之前，还包括：
向UE发送无线资源控制RRC层信令，以用于使UE在RRC层信令指示的第二时频资源上周期的进行上行数据的传输，第二时频资源包括CG-PUSCH(Configured Grant Physical Uplink Shared Channel，配置授权的物理上行共享信道)。
需要说明的是，在NR-U系统中，UE的上行传输分为2种方式，一种方式是动态调度，基站提前通过DCI调度，UE在接收到基站发送的DCI调度指令之后的某个时频资源位置上进行上行传输，时频资源可以为PUSCH。另一种方式是基站通过RRC层信令，预先配置周期的时频资源，UE可以在这些配置好的时频资源上周期的发送上行数据，周期的时频资源为CG-PUSCH。因此，基站不需要UE使用CUI-T或者其他功能的信号专门通知基站，基站都可以得知UE将在何时发起上行传输。
在一种实现的方式中，UE的上行传输都是被基站提前通过DCI动态调度的或者预先半静态配置的，因此，基站能确定UE将在何时发起上行传输，对于UE的上行传输，基站将在上行传输开始之前就发送信道占用指示，通知基站的相邻节点进行退避。UE在占用信道后，不需要向基站发送任何信道占用指示，就可以直接开始进行上行数据的传输。
在一种实现的方式中，在发送信道占用指示之后，还包括：
响应于连续N次未收到UE通过CG-PUSCH资源发送的上行信息，在第N+1次CG-PUSCH的时域资源之前，基站不发送信道占用指示，N为正整数。
在一种实现的方式中，N通过RRC层信令配置或协议预定。
在一种实现的方式中，对于配置授权的上行传输，UE有周期配置的资源，例如，CG-PUSCH。基站向UE发送RRC层信令，以用于使UE在RRC层信令指示的CG-PUSCH上周期的进行上行数据的传输；但是UE没有待传输的上行数据，在基站向UE发送了信道占用指示之后，基站没有接收到UE发送的上行数据，基站响应于连续N次未收到UE通过CG-PUSCH资源发送的上行数据，在第N+1次CG-PUSCH的时域资源之前，基站不发送信道占用指示。
在一种实现的方式中，通过DCI调度指令指示PUSCH为第一优先级。
在一种实现的方式中，第一优先级为高优先级，URLLC上行业务使用高优先级的PUSCH来调度。
在一种实现的方式中，通过RRC层信令，配置CG-PUSCH为第二优先级。第二优先级为高优先级。
在一种实现的方式中，发送信道占用指示，包括：
在确定出的信道占用指示的发送时机，发送信道占用指示；
确定信道占用指示的发送时机的方式，包括以下至少一项：
根据协议预定或高层配置的信道占用指示的发送时机与上行传输起始时间之间的时间间隔，确定信道占用指示的发送时机；
在上行传输开始之前的，且距离上行传输起始时间最近的周期配置的信道上发送信道占用指示，周期配置的信道包括广播信道及下行控制信道中的至少一项。
在一种实现的方式中，根据协议预定或高层配置的信道占用指示的发送时机与上行传输起始时间之间的时间间隔，确定信道占用指示的发送时机，发送时机包括在上行数据的传输开始之前的M个符号，M为正整数。
在一种实现的方式中，当基站需要在某种周期配置的信道上发送信道占用指示，基站可以在上行传输开始之前的，且距离上行传输起始时间最近的周期配置的信道上发送信道占用指示。该信道可以是广播信道、下行控制信道等。
本申请实施例中提供了另一种数据的传输方法，应用于UE，该方法的流程示意图如图4所示，该方法包括：
S201，接收基站发送的信道占用指示，信道占用指示用于指示UE进行上行传输。
在一种实现的方式中，基站在上行传输开始之前发送信道占用指示，通知基站的相邻节点进行退避。UE接收基站发送的信道占用指示，并在占用信道后，不需要向基站发送任何信道占用指示，就可以直接向基站发送上行数据。
S202，向基站发送上行数据。
在一种实现的方式中，信道占用指示，包括以下至少一项：
上行传输的起始位置；上行传输的时长信息；基站的标识。
在一种实现的方式中，当UE没有接收到基站发送的信道占用指示，UE不向基站发送上行数据。
本申请实施例中，UE接收基站发送的信道占用指示，信道占用指示用于指示UE进行上行传输；向基站发送上行数据。如此，实现了基站在UE的上行数据的传输开始之前就发送信道占用指示，指示基站的相邻节点进行退避，即指示基站的相邻节点不发送数据，指示UE进行上行数据的传输，使UE在占用信道后，不需要向基站发送信道占用指示，UE就可以直接开始进行上行数据的传输，从而解决了各隐藏节点干扰的问题，且能够节省传输资源。
本申请实施例中提供了又一种数据的传输方法，该方法的流程示意图如图5所示，该方法包括：
S301，基站向UE发送DCI调度指令或RRC层信令。
在一种实现的方式中，UE在接收到基站发送的DCI调度指令之后的某个时频资源位置上进行上行传输，时频资源可以为PUSCH；或基站通过RRC层信令，预先配置周期的时频资源，UE可以在这些配置好的时频资源上周期的发送上行数据，周期的时频资源为CG-PUSCH。
S302，基站进行空闲信道检测，确定干扰值。
S303，基站判断干扰值是否小于预设的能量检测阈值，当干扰值小于预设的能量检测阈值，基站检测到基站周围的信道空闲，则转到步骤S303处理；当干扰值不小于预设的能量检测阈值，基站检测到与基站相邻的各节点中有节点正在发送数据，则基站不发送信道占用指示给UE和各节点。
S304，基站发送信道占用指示给UE和各节点。
在一种实现的方式中，与基站相邻的各节点接收到该信道占用指示后，各节点不发送数据。
S305，UE根据信道占用指示，在DCI调度指令或RRC层信令指示的时频资源上将上行数据发送给基站。
在一种实现的方式中，UE在DCI调度指令指示的PUSCH的位置上进行上行数据的传输；或UE在RRC层信令指示的CG-PUSCH上周期的进行上行数据的传输。
本申请实施例中，基站通过向UE发送DCI调度指令或RRC层信令，即UE的上行数据的传输都是被基站提前通过DCI动态调度的或者预先半静态配置的，因此，基站能确定UE将在何时发起上行传输；基站在UE的上行传输开始之前就发送信道占用指示，指示各节点不发送数据，指示UE进行上行数据的传输，使UE在占用信道后，不需要向基站发送信道占用指示，UE就可以直接开始进行上行数据的传输，从而解决了各隐藏节点干扰的问题，且能够节省传输资源。

本申请实施例提供的计算机可读存储介质包括但不限于任何类型的盘(包括软盘、硬盘、光盘、CD-ROM、和磁光盘)、ROM(Read-Only Memory，只读存储器)、RAM(Random Access Memory，随即存储器)、EPROM(Erasable Programmable Read-Only Memory，可擦写可编程只读存储器)、EEPROM(Electrically Erasable Programmable Read-Only Memory，电可擦可编程只读存储器)、闪存、磁性卡片或光线卡片。也就是，可读存储介质包括由设备(例如，计算机)以能够读的形式存储或传输信息的任何介质。
应用本申请实施例，至少具有如下有益效果：
实现了基站在UE的上行数据的传输开始之前就发送信道占用指示，指示各节点进行退避，即指示各节点不发送数据，指示UE进行上行数据的传输，使UE在占用信道后，不需要向基站发送信道占用指示，UE就可以直接开始进行上行数据的传输，从而解决了各隐藏节点干扰的问题，且能够节省传输资源。
