Description

传输定时调整方法、装置及存储介质 技术领域
本公开涉及无线通信技术领域，尤其涉及一种传输定时调整方法、装置及存储介质。
背景技术
为了保证上行正交性，基站要求来自同一子帧但使用不同频域资源的不同用户设备的信号到达基站的时间基本上是对齐的。基站只要在循环前缀(CP，Cyclic Prefix)范围内接收到用户设备发送的上行数据，就能够正确的解码上行数据。因此，在相关技术的上行同步机制中，基站通过向用户设备指示提前时间(TA，Timing Advance)量化值以及时间偏移(TA-offset，Timing Advance offset)量化值，来使得基站调整上行传输定时，进而使得来自同一子帧的不同用户设备的信号到达基站的时间都落在CP范围内。
随着通信技术的发展，目前一种受网络控制的中继设备有望成为用来扩大小区覆盖范围的关键技术，通过中继设备转发用户设备或基站发送的信号，能够有效地扩大小区的覆盖范围。而在使用中继设备转发信号的情况下，将影响相关技术中的上行同步机制。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
需要说明的是，本申请中所有获取信号、信息或数据的动作都是在遵照所在地国家相应的数据保护法规政策的前提下，并获得由相应装置所有者给予授权的情况下进行的。
图1是根据一示例性实施例示出的一种无线通信系统的示意图，如图1所示，该通信系统中包括若干个用户设备11、中继设备12以及基站13。
其中，用户设备11可以是指向用户提供语音和/或数据连通性的设备。用户设备11可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信。用户设备11可以是物联网终端，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网终端的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，站(Station，STA)、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程终端(remote terminal)、接入终端(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户终端(User Equipment，UE)。或者，用户设备11也可以是无人飞行器的设备。或者，用户设备11也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线通信设备。或者，用户设备11也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
该中继设备12可以包括RU(repeater unit，响应单元)和MT(mobile terminal，移动终端)，MT用来接收并处理基站发送的控制信号，具有部分终端的功能；RU用来转发来自基站或者终端的信号。
智能超表面，或者IRS(Intelligent Reflection Surface)也被称为“可重构智能表面(RIS，reconfigurable intelligent surface)”或者“智能反射表面”。从外表上看，RIS是一张平平无奇的薄板。但是，它可以灵活部署在无线通信传播环境中，并实现对反射或者折射电磁波 的频率、相位、极化等特征的操控，从而达到重塑无线信道的目的。具体地说，RIS可以通过预编码技术，将入射到其表面的信号反射到特定的方向，从而增强接收端信号强度，实现对信道的控制。
由于智能中继设备和RIS在网络交互时具有类似的特性，因此，本公开中，中继设备，代指智能中继设备和RIS。
基站13可以是无线通信系统中的网络侧设备。其中，该无线通信系统可以是第四代移动通信技术(the 4th generation mobile communication，4G)系统，又称长期演进(Long Term Evolution，LTE)系统；或者，该无线通信系统也可以是5G系统，又称新空口(New Radio，NR)系统或5G NR系统。或者，该无线通信系统也可以是5G系统的再下一代系统。
其中，基站13可以是4G系统中采用的演进型基站(eNB)。或者，基站13也可以是5G系统中采用集中分布式架构的基站(gNB)。当基站12采用集中分布式架构时，通常包括集中单元(Central Unit，CU)和至少两个分布单元(Distributed Unit，DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体访问控制(Media Access Control，MAC)层的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本公开实施例对基站13的具体实现方式不加以限定。
各个用户设备11均能够与中继设备12通过无线空口建立无线连接，中继设备12也能够通过无线空口与基站13建立通信连接。在不同的实施方式中，该无线空口是基于第四代移动通信网络技术(4G)标准的无线空口；或者，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口；或者，该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
参照图1，用户设备11的信号经过中继设备12转发才能到达基站13，类似的，基站13发送的信号通过中继设备12转发才能到达用户设备11。值得说明的是，同一基站覆盖范围内的用户设备可以包括通过中继设备进行辅助通信的用户设备以及不需要通过中继设备进行辅助通信的设备，图1是以通过中继设备进行辅助通信的用户设备11进行的示意。
相关技术中，用户设备可以基于以下公式进行传输定时T_TA的计算：
T_TA＝(N_TA+N_TA,offset)*Tc，其中，N_TA为基站发送给用户设备的TA量化值，N_TA,offset为基站发送给用户设备的时间偏移量化值，用于表征基站进行上下行切换的时间，即在上行接收后，切换为下行发送所需要的时间，Tc为预定义的时间单位，在NR中表示最小采样间隔。
但在存在用户设备通过中继设备与基站进行通信的情况下，中继设备进行上下行切花也需要一定的时间，在此种情况下，采用相关技术确定用户设备的传输定可能会导致用户设备与基站之间不能上下行同步。
为了解决上述问题，本公开实施例提供一种传输定时调整方法、装置及存储介质。
图2是根据一示例性实施例示出的一种传输定时调整方法的流程图，如图2所示，该传输定时调整方法包括：
S201、基站确定第一时间偏移量化值。
其中，第一时间偏移量化值至少表征中继设备进行上下行切换的时间。
S202、基站根据第一时间偏移量化值和第二时间偏移量化值向用户设备发送定时提前偏移TA-offset量化值。
其中，第二时间偏移量化值至少表征基站进行上下行切换的时间，TA-offset量化值用于用户设备调整传输定时。
在一个示例中，针对中继设备的上下行切换，中继设备包括两条链路，第一链路从接 收切换至发送，第二链路从发送切换至接收。因此，第一时间偏移量化值可以包括中继设备的第一链路从接收切换至发送的时间，以及第二链路从发送切换至接收的时间。同样，第二时间偏移量化值也可以包括基站的第一链路从接收切换至发送的时间，以及第二链路从发送切换至接收的时间。
在一个示例中，基站的信号覆盖范围内包括的用户设备可以包括直接提供服务的用户设备(即用户设备与基站之间未经过中继设备进行信令转发)，下文其他实施例中也称第二用户设备，该第二用户设备包括了中继设备的MT部分。在此种情况下，第二用户设备的传输定时计算中，针对定时提前偏移TA-offset量化值，只用考虑基站的上下行切换时间，即可以只使用上述的第二时间偏移量化值计算传输定时。
在一个示例中，基站的信号覆盖范围内包括的用户设备还可以包括间接提供服务的用户设备(即用户设备与基站之间未经过中继设备进行信令转发)，下文其他实施例中也称第一用户设备。在此种情况下，第一用户设备的传输定时计算中，针对定时提前偏移TA-offset量化值，可以同时考虑基站的上下行切换时间以及中继设备的上下行切换时间，即可以使用上述的第一时间偏移量化值和第二时间偏移量化值计算传输定时。
采用上述方法，基站确定至少表征中继设备进行上下行切换的时间的第一时间偏移量化值，并根据第一时间偏移量化值和至少表征基站进行上下行切换的时间的第二时间偏移量化值向用户设备发送定时提前偏移TA-offset量化值。如此，用户设备根据接收到的TA-offset量化值调整传输定时，可以将中继设备进行上下行切换的时间加入基站与用户设备通信的上行定时提前的计算中，使得不同用户设备的上行信号到达基站的时间能够更准确的对齐。
图3是根据一示例性实施例示出的一种传输定时调整方法的流程图，如图3所示，该传输定时调整方法包括：
S301、基站确定第一时间偏移量化值。
其中，第一时间偏移量化值至少表征中继设备进行上下行切换的时间；
S302、基站通过UE-specific和/或UE-group specific信令向第一用户设备发送第一时间偏移量化值和第二时间偏移量化值的和值。
其中，基站覆盖范围内的用户设备包括第一用户设备，第一用户设备为通过中继设备进行辅助通信的用户设备。
在一个示例中，定时提前偏移TA-offset量化值可以是第一时间偏移量化值和第二时间偏移量化值的和值，即中继设备进行上下行切换的时间与基站进行上下行切换的时间的总和。
在一个示例中，在基站通过UE-specific和/或UE-group specific信令向第一用户设备发送第一时间偏移量化值和第二时间偏移量化值的和值之前，还可以确定中继设备相对第一用户设备透明。中继设备相对第一用户设备透明即表明第一用户设备不感知其与基站之间的通信是否通过中继设备转发，此种情况下，基站可以通过UE-specific和/或UE-group specific信令向第一用户设备发送第一时间偏移量化值和第二时间偏移量化值的和值，第一用户设备获取到该UE-specific和/或UE-group specific信令中包括的该和值后，即可根据该和值调整传输定时。
采用上述方法，对于通过中继设备进行辅助通信的用户设备，可以根据接收到的第一时间偏移量化值和第二时间偏移量化值的和值调整传输定时，使得不同用户设备的上行信号到达基站的时间能够更准确的对齐。
图4是根据一示例性实施例示出的一种传输定时调整方法的流程图，如图4所示，该传输定时调整方法包括：

其中，基站覆盖范围内的用户设备包括第一用户设备和第二用户设备，第一用户设备为通过中继设备进行辅助通信的用户设备，第二用户设备为未通过中继设备进行辅助通信的用户设备。
S403、基站广播第二时间偏移量化值。
在一个示例中，用户设备可以包括通过中继设备进行辅助通信的第一用户设备，也可以包括未通过中继设备进行辅助通信的第二用户设备。此种情况下，基站通过UE-specific和/或UE-group specific信令向第一用户设备发送第一时间偏移量化值，并广播第二时间偏移量化值。第一用户设备可以在接收到广播的第二时间偏移量化值的基础上加上第一时间偏移量化值，以根据第一时间偏移量化值和第二时间偏移量化值的和值调整传输定时。
在一个示例中，在基站通过UE-specific和/或UE-group specific信令向第一用户设备发送第一时间偏移量化值之前，还可以确定中继设备相对第一用户设备透明。中继设备相对第一用户设备透明即表明第一用户设备不感知其与基站之间的通信是否通过中继设备转发，此种情况下，基站可以通过UE-specific和/或UE-group specific信令向第一用户设备发送第一时间偏移量化值，第一用户设备获取到该UE-specific和/或UE-group specific信令中包括的第一时间偏移量化值后，即可根据第一时间偏移量化值以及第二时间偏移量化值调整传输定时。
采用本实施例，在基站覆盖范围内包括未使用中继设备进行辅助通信的第二用户设备，以及使用中继设备进行辅助通信的第一用户设备的情况下，基站可以向所有用户设备广播第二时间偏移量化值，并通过UE-specific和/或UE-group specific信令向第一用户设备发送第一时间偏移量化值，使得第二用户设备仅接收基站广播的第二时间偏移量化值，而第一用户设备可以接收到第一时间偏移量化值以及第二时间偏移量化值。进而第二用户设备可以根据第二时间偏移量化值调整传输定时，第一用户设备可以根据第一时间偏移量化值以及第二时间偏移量化值调整传输定时。
图5是根据一示例性实施例示出的一种传输定时调整方法的流程图，如图5所示，该传输定时调整方法包括：
S501、基站确定第一时间偏移量化值。

S502、基站广播第一时间偏移量化值以及第二时间偏移量化值。
在一个示例中，在基站广播第一时间偏移量化值以及第二时间偏移量化值之前，还可以确定中继设备相对第一用户设备不透明。中继设备相对第一用户设备不透明即表明第一用户设备能感知其与基站之间的通信是否通过中继设备转发。
采用上述方法，通过中继设备进行辅助通信的用户设备以及未通过中继设备进行辅助通信的用户设备均可以接收到第一时间偏移量化值以及第二时间偏移量化值，从而使得通过中继设备进行辅助通信的用户设备根据第一时间偏移量化值以及第二时间偏移量化值调整传输定时，未通过中继设备进行辅助通信的用户设备根据第二时间偏移量化值调整传输定时。
图6是根据一示例性实施例示出的一种传输定时调整方法的流程图，如图6所示，该传输定时调整方法包括：
S601、基站确定第一时间偏移量化值。
其中，第一时间偏移量化值至少表征中继设备进行上下行切换的时间；
S502、基站广播第二时间偏移量化值以及第一时间偏移量化值与第二时间偏移量化值 的和值。
在一个示例中，在基站广播第一时间偏移量化值以及第二时间偏移量化值之前，还可以确定中继设备相对第一用户设备不透明。中继设备相对第一用户设备不透明即表明第一用户设备能感知其与基站之间的通信是否通过中继设备转发。
采用上述方法，通过中继设备进行辅助通信的用户设备接收到基站广播的第二时间偏移量化值以及第一时间偏移量化值与第二时间偏移量化值的和值后，可以根据第一时间偏移量化值与第二时间偏移量化值的和值调整传输定时。未通过中继设备进行辅助通信的用户设备接收到基站广播的第二时间偏移量化值后，可以根据第二时间偏移量化值调整传输定时。

S702、基站根据第一时间偏移量化值和第二时间偏移量化值向用户设备发送定时提前偏移TA-offset量化值。
其中，第二时间偏移量化值至少表征基站进行上下行切换的时间，TA-offset量化值用于用户设备调整传输定时。
在一个示例中，中继设备向基站上报的能力报文中包括时间偏移量化值，也即是说，第一时间偏移量化值可以放在中继设备上报的能力报文中进行上报，比如可以放在repeater-MT capability中进行上报。
采用上述方法，通过获取中继设备上报的能力报文，可以获取更准确的第一时间偏移量化值。
图8是根据一示例性实施例示出的一种传输定时调整方法的流程图，如图8所示，该传输定时调整方法包括：
S801、基站获取中继设备上报的能力报文中包括的索引值。
S802、基站根据索引值，确定第一时间偏移量化值。

在一个示例中，第一时间偏移量化值可以是索引值，比如capability class index，不同的index可以对应不同的值，索引值放在中继设备上报的能力报文中。
采用上述方法，可以通过获取中继设备上报的能力报文中包括的索引值，获取更准确的第一时间偏移量化值。
图9是根据一示例性实施例示出的一种传输定时调整方法的流程图，如图9所示，该传输定时调整方法包括：
S901、基站将预设的默认值确定为第一时间偏移量化值。
其中，第一时间偏移量化值至少表征中继设备进行上下行切换的时间；
S902、基站根据第一时间偏移量化值和第二时间偏移量化值向用户设备发送定时提前偏移TA-offset量化值。
其中，第二时间偏移量化值至少表征基站进行上下行切换的时间，TA-offset量化值用于用户设备调整传输定时。
在一个示例中，第一时间偏移量化值可以是预设的默认值，比如{FR1,10us；FR2,8us}， 此时则不需要中继设备进行上报，用户设备可以直接根据预设的默认值调整传输定时。
采用上述方法，用户设备可以根据预设的默认值调整传输定时，无需中继设备上报，减少信令开销。
图10是根据一示例性实施例示出的一种传输定时调整方法的流程图，如图10所示，该传输定时调整方法包括：
S1001、基站在未获取到中继设备上报的第一时间偏移量化值的情况下，将预设的默认值确定为第一时间偏移量化值。
其中，第一时间偏移量化值至少表征中继设备进行上下行切换的时间；
S1002、基站根据第一时间偏移量化值和第二时间偏移量化值向用户设备发送定时提前偏移TA-offset量化值。
其中，第二时间偏移量化值至少表征基站进行上下行切换的时间，TA-offset量化值用于用户设备调整传输定时。
在一个示例中，基站在未获取到中继设备上报的第一时间偏移量化值的情况下，可以将预设的默认值确定为第一时间偏移量化值，用户设备根据预设的默认值调整传输定时。基站在获取到中继设备上报的第一时间偏移量化值的情况下，用户设备根据获取到的第一时间偏移量化值调整传输定时。
在图1-图10所示的根据一示例性实施例示出的一种传输定时调整方法中，不同的频段(frequency band)可以对应有不同的时间偏移量化值。因此，在一个示例中，第一时间偏移量化值可以包括对应不同频段的量化值。也即是说，第一时间偏移量化值可以是一组值，包括多个量化值，每一量化值对应有不同的频段，比如上报的内容为{FR1,1000；FR2,800}，即频段FR1的量化值为1000，频段FR2的量化值为800。
并且，在另一个示例中，第一时间偏移量化值的时间单位为绝对时间单位，比如us，ns等，或者，第一时间偏移量化值的时间单位为无线通信系统中的时间单元。无线通信系统中的时间单位可以是物理层的最小采样间隔Tc，或者物理层的其他时间长度，例如symbol、slot等。本公开实施例对此不作限定。
