Description

一种参考信号的发送方法、装置以及存储介质
本申请要求于2018年11月02日提交中国专利局、申请号为201811299329.7、名称为“一种参考信号的发送方法和装置”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
本发明涉及通信技术.域，特别涉及一种参考信号的发送方法、装置以及存储介质。
背景
支持无线回传中继链路能够实现更加灵活和密集的小区部署。由于未来移动通信系统可提供的带宽更大，同时还能够部署大规模多输入多输出(MIMO：Multiple-Input Multiple-Output)系统或者多波束系统，给部署统一的接入和回传链路提供了机会，使得密集网络部署变得更加简单容易。
中继节点可以在时间，频率或者空间上复用接入和回传链路。接入和回传链路可能是在相同的频段或者在不同频段上，当接入和回传链路在同频上时，要求更加紧凑的互操作来配置双工限制避免干扰。
在中继节点的发现过程中，一个中继节点需要检测参考信号，即同步序列块(SSB：Synchronous sequence block)信号，来发现新的中继节点，同时也需要发送参考信号用来其他中继节点发现本中继节点。受限于双工的限制，中继节点不能同时接收和发送参考信号，因此，中继节点要协调好参考信号的收发关系。
技术内容

所述确定单元，用于根据本中继节点的跳数确定周期性发送同步序列块SSB信号的时间位置；
所述发送单元，用于使用与第一节点在所述发送单元确定的同一时间位置的不同SSB块上发送SSB信号；其中，所述第一节点为同本中继节点跳数相同的中继节点。

实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，下面结合附图并举实施例，对本发明的技术方案进行详细说明。
本申请实施例提供一种参考信号的发送方法，应用于任一中继节点上，该中继节点根据自身的跳数确定周期性发送同步序列块SSB信号的时间位置；并且相同跳数的中继节点发送SSB信号的SSB块均不相同。该方案保证中继节点发送SSB信号的正交性，以避免收发信号的干扰。
通常情况下，在无线通信中，信息不是直接从基站到终端的一次传输，而是经过从基站到终端之间的多个中继节点的转发，即信息的传输是通过链路上的多个中继节点的转发完成的。
在一些实施例中，一个中继节点位于基站到终端之间的位置，也即位于基站到终端之间的第几跳，就是该中继节点的跳数，这里，多跳就是多次转发。
本申请实施例中，在确定中继节点的跳数，以及确定发送SSB信号的位置时，存在两种实现方式，具体如下：
第一种；通过检测其它中继节点发送的SSB信号实现，具体为：
通过检测上一跳中继节点发送的SSB信号，确定上一跳中继节点 发送SSB信号的周期性时间位置；
根据上一跳中继节点发送SSB信号的周期性时间位置确定上一跳中继节点的跳数，进一步确定本中继节点的跳数。
根据配置信息确定本中继节点所处跳数对应的发送SSB信号的周期性时间位置；
通过检测周期性时间位置上的SSB块被占用的情况，使用未被占用的SSB块发送SSB信号；或，在确定的周期性时间位置上随机选择SSB块发送SSB信号。
第二种：通过网络设备发送的公共控制信令和专用信令实现，具体为：
网络设备向中继节点发送公共控制信令和专用信令；其中，所述公共控制信令中携带每个中继节点的跳数；所述公共控制信令携带每一跳中继节点周期性发送SSB信号的时间位置；所述专用信令携带正交扩频码信息。
中继点接收网络设备发送的公共控制信令；根据接收到的公共控制信令确定本中继节点的跳数；根据接收到的公共控制信令确定每一跳中继节点周期性发送SSB信号的时间位置。
中继节点接收网络设备发送的专用信令；根据所述专用信令确定与本节点相同跳数的中继节点发送SSB信号的SSB块的位置。
网络设备发送公共信令时，周期性发送，或者中继节点的跳数变化时发送。
图1A为本申请实施例提供的参考信号的发送方法的应用场景的系统结构示意图，在本发明本申请实施例的应用场景中，包括基站11、中继节点12以及终端13。
其中，基站11可以发送回传链路的下行数据；以及接收回传链 路的上行数据。中继节点12，根据本中继节点的跳数确定周期性发送同步序列块SSB信号的时间位置；并使用与第一节点在同一时间位置的不同SSB块上发送SSB信号；其中，所述第一节点为同所述本中继节点跳数相同的中继节点；
终端13，发送接入链路的上行数据；并接收接入链路的下行数据。更进一步的，终端13还可以接收各自的OCC信息，用于找到发送SSB的时间位置。
下面结合附图，详细说明本申请实施例中参考信号的发送过程。
参见图1B，图1B为本申请实施例提供的参考信号的发送方法的流程示意图。具体步骤为：
步骤101，中继节点根据本中继节点的跳数确定周期性发送同步序列块SSB信号的时间位置。
参见图2，图2为本申请实施例所述的4跳中继节点在基础周期发送SSB信号的位置示意图。
图2中以20ms为一周期，在每个周期中第一个时间位置用于跳数为1的中继节点(1st hop RN:1st hop Relay Node)发送SSB信号，第二个时间位置用于跳数为2的中继节点(2st hop RN)发送SSB信号；第三个时间位置用于跳数为3的中继节点(3st hop RN)发送SSB信号；第四个时间位置用于跳数为4的中继节点(4st hop RN)发送SSB信号。
参见图3，图3为本申请实施例所述的4跳中继节点在3倍基础周期发送SSB信号的位置示意图。
图3中以60ms为一周期，在每个周期中第一个时间位置用于跳数为1的中继节点(1st hop RN)发送SSB信号，第四个时间位置用于跳数为2的中继节点(2st hop RN)发送SSB信号；第七个时间位 置用于跳数为3的中继节点(3st hop RN)发送SSB信号；第10个时间位置用于跳数为4的中继节点(4st hop RN)发送SSB信号。
步骤102，该中继节点使用与第一节点在同一时间位置的不同SSB块上发送SSB信号；其中，所述第一节点为同本中继节点跳数相同的中继节点。
参见图4、图4为本申请实施例所述的同一时间位置的不同SSB块上发送SSB信号的示意图。图4以图1B中的第一跳中继节点在第三周期的第一时间位置上选择SSB块为例，假设处于第一跳的中继节点的节点个数为4，分别为RN1、RN2、RN3和RN4。
针对第三周期第一时间位置上的SSB块从左到右，以两组标号表示，从左到右分别为：第一组、第二组。
RN1选择第一组标号为2和3组成的SSB块发送SSB信号，RN2选择第一组标号为4和5组成的SSB块发送SSB信号；RN3选择第二组标号为1和2组成的SSB块发送的SSB信号；RN4选择第二组标号为3和4组成的SSB块发送SSB信号。
通过上述实现，可以保证发送SSB信号的正交性，进而避免干扰。
该中继节点使用与第一节点在同一时间位置的不同SSB块上发送SSB信号的具体实现可以为：
使用与第一节点不同的扩频码字，用于选择发送所述SSB信号的时间位置中的SSB块的位置。
如图4中第一跳中继节点个数是4，每个中继节点选择不同的扩频码字，RN1选择[1000]，就只在SSB块1上发送，而RN2选择[0100]，就只在SSB块2上发送，RN3选择[0010]，就只在SSB块3上发送，RN4选择[0001]，就只在SSB块4上发送。
上述给出一种实现正交性的一种具体实现方式，具体实现正交性的方式不限于上述给出的实现方式。
中继节点在不同的发送周期使用不同位置的SSB块，或相同位置的SSB块发送SSB信号。
相同跳数中继节点在不同的发送周期内使用不同位置SSB块发送SSB信号。中继节点在不同的发送周期使用不同位置的SSB块发送SSB信号时，可以获得分级特性。
图4中给出的是第三周期第一时间位置上四个中继节点发送SSB信号的SSB块的示意图。如果在第三周期第一时间位置上可以在发送RN1的SSB块上发送RN3的SSB信号，可以在发送RN2的SSB块上发送RN4的SSB信号；可以在发送RN3的SSB块上发送RN1的SSB信号；可以在发送RN4的SSB块上发送RN2的SSB信号。
这仅仅是一种举例，具体实现时不限于上述实现，只要保证在不同的发送周期使用不同的SSB块发送SSB信号即可。
基于同样的发明构思，本申请实施例中还提供一种参考信号的发送装置，应用于任一中继节点上。参见图5，图5为本申请实施例提供的参考信号的发送装置的结构示意图。该装置包括：确定单元501和发送单元502；
确定单元501，用于根据本中继节点的跳数确定周期性发送同步序列块SSB信号的时间位置；
发送单元502，用于使用与第一节点在发送单元502确定的同一时间位置的不同SSB块上发送SSB信号；其中，所述第一节点为同本中继节点跳数相同的中继节点。
较佳地，
确定单元501，进一步用于使用与第一节点不同的扩频码字，用于选择发送所述SSB信号的时间位置中的SSB块的位置；
发送单元502，进一步用于在不同的发送周期使用不同位置的SSB块发送SSB信号。
上述实施例的单元可以集成于一体，也可以分离部署；可以合并为一个单元，也可以进一步拆分成多个子单元。
综上所述，本申请通过中继节点根据自身的跳数确定周期性发送同步序列块SSB信号的时间位置；并且相同跳数的中继节点发送SSB信号的SSB块均不相同。该方案保证中继节点发送SSB信号的正交性，以避免收发信号的干扰。

在一个实施例中，输入接口603可以是一些网络接口或者用户接口。
所述存储装置605可以包括易失性存储器(volatile memory)，如随机存取存储器(random-access memory，RAM)；存储装置605也可以包括非易失性存储器(non-volatile memory)，如快闪存储器(flash memory)，固态硬盘(solid-state drive，SSD)等；存储装置605还可以包括上述种类的存储器的组合。
所述处理器601可以是中央处理器(central processing unit，CPU)。在一个实施例中，所述处理器601还可以包括硬件芯片。上述硬件芯片可以是专用集成电路(application-specific integrated circuit，ASIC)，可编程逻辑器件(programmable logic device，PLD) 等。上述PLD可以是现场可编程逻辑门阵列(field-programmable gate array，FPGA)，通用阵列逻辑(generic array logic，GAL)等。
在一个实施例中，所述存储装置605还用于存储程序指令。所述处理器601可以调用所述程序指令，实现上述提及的各种方法和步骤。
