Description

通信链路定时方法、装置、通信节点设备及计算机存储介质

技术领域
本公开涉及通信领域，例如涉及一种通信链路定时方法、装置、通信节点设备及计算机存储介质。
背景技术
在无线通信系统中，每个终端与基站之间的距离不同，但是要保证每个终端发射的数据同时到达基站侧。相关的定时机制如下：基站通过时间提前量命令(Timing Advance Command，TAC)通知终端提前多少时间进行发射，终端收到TAC后进行相应的定时，从而在对应的时间点提前发射，但这种情况仅针对终端与基站直连的情况，此时终端到基站的通信通路上只有基站和终端。但针对引入中继节点设备后的通信系统，终端可通过中继节点设备连接到基站，也即此时终端到基站的通信通路上至少具有两个通信节点设备。例如引入第一中继节点设备时，终端通过第一中继节点设备与基站连接，此时终端到基站的通信通路上具有第一中继节点设备和基站两个通信节点设备；又例如引入第一中继节点设备和第二中继节点设备时，至少部分终端可通过第一中继节点设备和第二中继节点设备与基站连接，此时终端到基站的通信通路上具有第一中继节点设备、第二中继节点设备和基站三个通信节点设备，以此类推。针对引入中继节点设备的通信系统，如何保证每个终端发射的数据同时到达基站侧的定时机制并未提出。

具体实施方式
下面通过实施方式结合附图对本公开实施例进行说明。此处所描述的实施例仅仅用以解释本公开，并不用于限定本公开。
实施例一
本实施例提供的通信链路定时方法适用于一种或多种通信系统，包括但不 限于第四代无线通信(the 4th Generation Mobile Communication，4G)系统，新无线接入系统(New Radio，NR)系统(或称为第五代移动通信(5th-Generation，5G)系统)，5G系统之后的新一代无线通信系统等。
5G系统或5G系统之后的新一代无线通信系统将会采用比4G系统所采用的载波频率更高的载波频率进行通信，例如采用28GHz、45GHz、70GHz等等，但是，由于高频通信对应的载波频率具有更短的波长，所以可以保证单位面积上能容纳更多的天线元素，而更多的天线元素意味着可以采用波束赋形的方法来提高天线增益，从而保证高频通信的覆盖性能。同时，针对覆盖范围的挑战，无线回程传输也可以解决这个问题。但回程链路(Backhaul link，BL)和接入链路(Access link，AL)之间存在收发自干扰。针对自干扰问题，则可通过BL和AL之间采用时分复用、空分复用、频分复用等传输方式解决。
另外，为了便于理解，先对本实施例中涉及的通信通路进行解释说明。本实施例中的通信通路上包括至少两个通信节点设备(也即至少两个跃点(hop))。例如，假设一个通信系统包括4个hops，参见图1所示，分别为基站(该基站可以是5G系统的基站(gNB)，也可以时其他基站)、以及三个中继节点(Relay Node，RN)设备，三个RN设备分别为RN1、RN2、RN3，一种拓扑连接结构为基站、RN1、RN2、RN3依次相连(当然应当理解的是实际的拓扑连接结构可根据实际应用场景确定)，且设接入到基站的终端为UE0，接入到RN1的终端为UE1，接入到RN2的终端为UE2，接入到RN3的终端为UE3。在图1中，包括至少两个通信节点设备的通信通路则至少包括：UE1-RN1-基站，UE2-RN2-RN1-基站，UE3-RN3-RN2-RN1-基站。
为了便于理解，下面分别以UE3-RN3-RN2-RN1-基站这一通信通路进行示例说明。
参见图2所示，在UE3-RN3-RN2-RN1-基站这一通信通路中，RN1-基站之间的链路为RN2-RN1之间的链路的前一跳链路，RN2-RN1之间的链路为RN3-RN2之间的链路的前一跳链路，RN3-RN2之间的链路为UE3-RN3之间的链路的前一跳链路；针对RN2、RN1、基站这三个通信节点，BL1表示基站和 RN1之间的回程链路，AL1表示RN1和RN2之间的接入链路；针对RN3、RN2、RN1这三个通信节点，BL2表示RN1和RN2之间的回程链路，AL2表示RN2和RN3之间的接入链路；针对UE3、RN3、RN2这三个通信节点，BL3表示RN2和RN3之间的回程链路，AL3表示UE3和RN3之间的接入链路。根据图2所示可知，本实施例中通信通路上的链路对可能是由BL和AL组成，也可能是由BL和BL组成，或者AL和AL组成。应当理解的是，图2所示的通信通路仅仅是一种示例，对于通信通路上的hops少于图2所示的，或大于图2所示的通信通路则以此类推，在此不再赘述。
基于上述示例说明，本实施例提供的一种通信链路定时方法参见图3所示，包括：
S310：基于通信通路上当前链路收发两端的信号传输时间PT、所述当前链路在所述通信通路上前一跳链路的时间调整量，确定通信通路上当前链路的时间调整量。
本实施例中，通信通路上当前链路的时间调整量，是基于当前链路收发两端的信号传输时间(Propagation Time，PT)，当前链路在所述通信通路上前一跳链路的时间调整量确定的。因此，当确定通信通路上当前链路的时间调整量时，可以先获取当前链路收发两端的信号传输时间PT和当前链路在通信通路上前一跳链路的时间调整量，根据获取的PT和前一跳链路的时间调整量确定前链路的时间调整量。且获取方式在本实施例中不做限制。
S320：根据当前链路的时间调整量设置当前链路的信号发射时间。
本实施例针对通信通路上的一个或多个链路都可以通过图3所示的方法完成信号发射时间的设置，从而保证多个通信通路上的终端发送的数据同时到达基站侧。
本实施例中，链路收发两端的信号传输时间是指链路两端的节点之间收发信号的传输时间，例如图2中基站和RN1之间的链路，其两端的信号传输时间就是指基站与RN1这两端的信号PT。在一实施例中，该PT可由基站获取，基站还可以将获取的PT下发给RN1。
本实施例中，链路的时间调整量为：链路上的通信节点设备开始发射信号时刻的边界，相对于开始接收信号时刻的边界的时间偏移量。例如，对于基站和RN1之间的链路，时间调整量为通信节点RN1开始发射信号时刻的边界，相对于开始接收信号时刻的边界的时间偏移量。
本实施例提供的通信链路定时方法适用于包括至少两个通信节点设备的通信通路。
在本实施例中，当链路在通信通路上前一跳链路的时间调整量等于0时，表明前一跳链路上的通信节点设备始发射信号时刻的边界，与开始接收信号时刻的边界对齐，此时当前链路的时间调整量由当前链路的PT决定。例如在图2中，基站和RN1之间的链路就没有前一跳链路，可认为其前一跳链路的时间调整量等于0，此时基站和RN1之间的这一链路的时间调整量就等于该链路的2倍PT。
应当理解的是，本实施例中基于通信通路上当前链路收发两端的信号传输时间PT，当前链路在通信通路上前一跳链路的时间调整量，确定当前链路的时间调整量，可以包括直接仅基于通信通路上当前链路收发两端的信号传输时间PT，以及当前链路在通信通路上前一跳链路的时间调整量，确定当前链路的时间调整量；为了提升提定时的准确性、可靠性以及其他需求，也可灵活的结合其他因素进行当前链路的时间调整量的确定。为了便于理解，本实施例以结合通信通路上一个或多个链路对的复用方式为例进行示例说明。
例如，在本实施例中，当通信通路上每个链路对采用时分复用(Time Division Multiplexing，TDM)或频分复用(Frequency Division Multiplexing，FDM)中的同向通信(即通信节点设备(例如RN)针对不同链路用不同频率资源同时执行接收和发射)频分复用FDM-1(即以FDM的方式同向通信)时，根据获取的PT、前一跳链路的时间调整量确定当前链路的时间调整量包括：
确定当前链路的时间调整量TimeAdjustment_hop(n+1)＝TimeAdjustment_hop(n)+2*PT，其中n为大于或等于0的整数，TimeAdjustment_hop(n)为前一跳链路的时间调整量；也即为前一跳链路的时间调 整量加上当前链路的2倍PT。
在本实施例中，当通信通路上每个链路对采用空分复用(Spatial Division Multiplexing，SDM)或FDM中的异向通信(即通信节点设备(例如RN)针对不同链路用不同频率资源同时执行接收或发射)频分复用FDM-2(即以FDM的方式异向通信)时，根据获取的PT、前一跳链路的时间调整量确定当前链路的时间调整量包括：
在当前链路为奇数跳链路的情况下，确定链路的时间调整量TimeAdjustment_hop(2n+1)＝TimeAdjustment_hop(2n)+2*PT，其中n为大于或等于0的整数，TimeAdjustment_hop(2n)为前一跳链路的时间调整量，也即为前一跳链路的时间调整量加上当前链路的2倍PT；
在当前链路为偶数跳链路的情况下，确定当前链路的时间调整量TimeAdjustment_hop(2n+2)＝TimeAdjustment_hop(2n+1)-2*PT，其中n为大于或等于0的整数，TimeAdjustment_hop(2n+1)为前一跳链路的时间调整量，也即为前一跳链路的时间调整量减当前链路的2倍PT；本实施例中时间调整量取值为正表示为时间滞后量，取值为负表示为时间提前量。
在本实施例中，通信通路上第一链路对采用TDM或FDM-1，后续的每个链路对均采用TDM、SDM、FDM-1或FDM-2时，根据获取的PT、前一跳链路的时间调整量确定当前链路的时间调整量包括：
确定当前链路的时间调整量TimeAdjustment_hop(n+1)＝TimeAdjustment_hop(n)+2*PT，n为大于或等于0的整数，TimeAdjustment_hop(n)为前一跳链路的时间调整量，也即为前一跳链路的时间调整量加上当前链路的2倍PT。
在本实施例中，通信通路上第一链路对采用SDM，后续的每个链路对采用TDM、FDM-1或FDM-2时，或通信通路上第一链路对采用FDM-2，后续的每个链路对采用TDM、SDM或FDM-1时，根据获取的PT、前一跳链路的时间调整量确定当前链路的时间调整量包括：
确定当前链路的时间调整量TimeAdjustment_hop(n+1)＝TimeAdjustment_hop(n)-2*PT，n为大于或等于0的整数，TimeAdjustment_hop(n)为前一跳链路的时间调整量。
在本实施例中，通信通路上第一链路对采用SDM，第二链路对采用TDM或FDM-1，后续的每个链路对采用TDM、SDM、FDM-1或FDM-2时，根据获取的PT、前一跳链路的时间调整量确定当前链路的时间调整量包括：
确定当前链路的时间调整量TimeAdjustment_hop(n+1)＝TimeAdjustment_hop(n)-2*PT，n为大于或等于0的整数，TimeAdjustment_hop(n)为前一跳链路的时间调整量。
本实施例中，通信通路上第一链路对采用SDM，第二链路对采用SDM或FDM-2，后续的每个链路对采用TDM、SDM、FDM-1或FDM-2时，根据获取的PT、前一跳链路的时间调整量确定当前链路的时间调整量包括：
在当前链路为通信通路上的第三跳及之后的链路的情况下，确定链路的时间调整量TimeAdjustment_hop(n+1)＝TimeAdjustment_hop(n)+2*PT，n为大于或等于0的整数，TimeAdjustment_hop(n)为前一跳链路的时间调整量。
本实施例中，图3所示的通信链路定时方法可适用于初始接入阶段，此时链路传输的信息为随机接入响应信息。当然，也可适用于其他阶段。
在本实施例中，当当前链路传输的信息为非随机接入响应信息时，也即接入之后的阶段，此时确定当前链路的时间调整量可选的可采用以下方式：
确定当前链路的时间调整量为当前链路前一时刻采用的时间调整量加上修正时间调整量。
本实施例中修正时间调整量的获取方式可以采用多种方式，例如可以监测根据前一时刻采用的时间调整量所发送的信号的接收时间，并将该接收时间与预设的标准时间范围进行比对，得到修正时间调整量。在本实施例中，当修正时间调整量等于0时，根据前述公式可知此时当前链路的时间调整量与前一时刻采用的时间调整量相同，当修正时间调整量大于0时，得到的链路的时间调 整量相对于前一时刻的时间调整量提前，当修正时间调整量小于0时，得到的链路的时间调整量相对于前一时刻的时间调整量滞后。
本实施例首先针对引入了至少一个中继节点设备的通信通路上的每个链路，可根据每个链路收发两端的信号传输时间PT、每个链路之前一跳链路的时间调整量确定出每个链路的时间调整量，进而根据每个链路的时间调整量设置每个链路的信号发射时间，从而保证数据同时到达上层节点，且不会产生干扰，又能灵活地在多个链路对之间采用相同或不同复用方式。
实施例二
本实施例还提供了一种通信链路定时装置，该通信链路定时装置可以设置于通信系统中用于通信链路定时设置的设备上，也可设置于通信通路上的通信节点设备上，参见图4所示，该通信链路定时装置包括：
处理模块42，设置为基于通信通路上当前链路收发两端的信号传输时间PT，当前链路在通信通路上前一跳链路的时间调整量，确定当前链路的时间调整量。
设置模块43，设置为根据当前链路的时间调整量设置当前链路的信号发射时间。
本实施例中，针对通信通路上的一个或多个链路都可通过图4所示的通信链路定时装置完成信号发射时间的设置，从而保证多个通信通路上的终端发送的数据同时到达基站侧。
本实施例中，链路收发两端的信号传输时间是指链路两端的节点之间收发信号的传输时间。链路的时间调整量为：链路上的通信节点设备开始发射信号时刻的边界，相对于开始接收信号时刻的边界的时间偏移量。
在本实施例中，当链路在通信通路上前一跳链路的时间调整量等于0时，表明前一跳链路上的通信节点设备始发射信号时刻的边界，与开始接收信号时刻的边界对齐，此时处理模块42确定当前链路的时间调整量由当前链路的PT决定。
本实施例提供的通信链路定时方法适用于包括至少两个通信节点设备的通 信通路。
应当理解的是，本实施例中处理模块42基于通信通路上当前链路收发两端的信号传输时间PT，当前链路在通信通路上前一跳链路的时间调整量，确定当前链路的时间调整量，可以包括直接仅基于通信通路上当前链路收发两端的信号传输时间PT，以及当前链路在通信通路上前一跳链路的时间调整量确定当前链路的时间调整量；为了提升提定时的准确性、可靠性以及其他需求，处理模块42也可灵活的结合其他因素进行当前链路的时间调整量的确定。为了便于理解，本实施例以结合通信通路上一个或多个链路对的复用方式为例进行示例说明。
此时，在本实施例中，参见图4所示，通信链路定时装置还可包括获取模块41，设置为在处理模块42根据当前链路收发两端的信号传输时间PT，当前链路在通信通路上前一跳链路的时间调整量，确定当前链路的时间调整量之前，获取通信通路上的一个或多个链路对的复用方式；在一实施例中，当前链路收发两端的信号传输时间PT，该当前链路在通信通路上前一跳链路的时间调整量也可由处理模块42获取。
此时，处理模块42可结合一个或多个链路对的复用方式确定当前链路的时间调整量。
在一实施例中，本实施例中的获取模块41、处理模块42和设置模块43的功能可通过其所在设备的处理器或控制器实现。
本实施例中，处理模块42是设置为在通信通路的每个链路对采用TDM或FDM-1的情况下，或复用方式为通信通路上第一链路对采用TDM或FDM-1，后续的每个链路对采用TDM、SDM、FDM-1或FDM-2时，确定当前链路的时间调整量TimeAdjustment_hop(n+1)＝TimeAdjustment_hop(n)+2*PT，n为大于或等于0的整数，TimeAdjustment_hop(n)为前一跳链路的时间调整量。
本实施例中，处理模块42是设置为在通信通路的每个链路对采用SDM时或FDM-2的情况下，当当前链路为奇数跳链路时，确定当前链路的时间调整量TimeAdjustment_hop(2n+1)＝TimeAdjustment_hop(2n)+2*PT，n为大于或等于0 的整数，TimeAdjustment_hop(2n)为前一跳链路的时间调整量；以及，
当当前链路为偶数跳链路时，确定当前链路的时间调整量TimeAdjustment_hop(2n+2)＝TimeAdjustment_hop(2n+1)-2*PT，n为大于或等于0的整数，TimeAdjustment_hop(2n+1)为前一跳链路的时间调整量，时间调整量取值为正表示为时间滞后量，取值为负表示为时间提前量。
本实施例中，处理模块42是设置为在通信通路上第一链路对采用SDM，后续的每个链路对采用TDM、FDM-1或FDM-2的情况下，或复用方式为通信通路上第一链路对采用FDM-2，后续的每个链路对采用TDM、SDM或FDM-1时，或复用方式为通信通路上第一链路对采用SDM，第二链路对采用TDM或FDM-1，后续的每个链路对采用TDM、SDM、FDM-1或FDM-2时，确定当前链路的时间调整量TimeAdjustment_hop(n+1)＝TimeAdjustment_hop(n)-2*PT，n为大于或等于0的整数，TimeAdjustment_hop(n)为前一跳链路的时间调整量。
本实施例中，处理模块42是设置为在通信通路上第一链路对采用SDM，第二链路对采用SDM或FDM-2，后续的每个链路对采用TDM、SDM、FDM-1或FDM-2时，且当当前链路为通信通路上的第三跳及之后的链路时，确定当前链路的时间调整量TimeAdjustment_hop(n+1)＝TimeAdjustment_hop(n)+2*PT，n为大于或等于0的整数，TimeAdjustment_hop(n)为前一跳链路的时间调整量。
本实施例中，图4所示的上述定时方案可适用于初始接入阶段，此时链路传输的信息为随机接入响应信息。当然，也可适用于其他阶段。
在本实施例中，当当前链路传输的信息为非随机接入响应信息时，也即接入之后的阶段，此时通信链路定时装置的处理模块42可采用以下方式确定当前链路的时间调整量：
处理模块42确定当前链路的时间调整量为当前链路前一时刻采用的时间调整量加上修正时间调整量。
本实施例中修正时间调整量的获取方式可以采用多种方式，例如可以监测根据前一时刻采用的时间调整量所发送的信号的接收时间，并将该接收时间与 预设的标准时间范围进行比对，得到修正时间调整量。在本实施例中，当修正时间调整量等于0时，根据前述公式可知此时当前链路的时间调整量与前一时刻采用的时间调整量相同，当修正时间调整量大于0时，得到的当前链路的时间调整量相对于前一时刻的时间调整量提前，当修正时间调整量小于0时，得到的当前链路的时间调整量相对于前一时刻的时间调整量滞后。
本实施例提供的通信链路定时装置针对引入了至少一个中继节点设备的通信通路上的每个链路，可确定出每个链路的时间调整量，进而根据每个链路的时间调整量设置每个链路的信号发射时间，从而保证数据同时到达上层节点，且不会产生干扰，又能灵活地在多个链路对之间采用相同或不同复用方式。
