本申请主张在2020年10月23日在中国提交的中国专利申请号202011150338.7的优先权，其全部内容通过引用包含于此。
技术领域
本申请涉及通信技术领域，具体而言，涉及一种无线通信方法、一种无线通信装置、一种中继设备、一种远端设备、一种基站和一种可读存储介质。
背景技术
在第五代(the fifth generation，5G)移动通信技术中，随着海量设备将接入到蜂窝网络，核心网络压力陡增。3GPP(the third generation parmership project)提出了设备到设备通信(Device-to-Device，D2D)，服务于近距离场景。对于功率受限的远端设备(remote user equipment，remote UE)，可以通过中继设备(relay user equipment，relay UE)与基站(gNB)通信，从而减小远端设备的功率消耗。其中，从通信原理上来说，可以通过Uu接口(用户设备与基站之间的接口)和PC5接口(用户设备与用户设备之间的接口)来进行通信，远端设备和中继设备之间的链路为旁链路(sidelink)，该旁链路之间的无线链路又称为PC5链路，中继设备跟基站之间的链路称为Uu链路(Uulink)。
相关技术中，当远端设备进行中继通信时，需要联合服务小区系统消息和单边带(Single side band，SSB)物理信号来确定中继设备Uu接口的具体时间，但是对于处于服务小区覆盖外的远端设备无法通过中继设备转发的系统消息来获取Uu接口的系统帧号等信息。这会导致远端设备无法准确预判Uu接口的发出的广播信号的发送时间窗位置，例如，SSB信号、物理广播信道(PBCH)信号、系统信息信号(SIB)等，使得远端设备盲测无线小区，不仅延时大，而且功耗高。另外，基站也无法为处于覆盖外的远端设备配置测量间隙(measurement gap，MG)，使得远端设备无法及时根据测量间隙找到目标小区，无法保证通信业务连续性。

具体实施方式
为了能够更清楚地理解本申请的上述目的、特征和优点，下面结合附图和具体实施方式对本申请进行进一步的详细描述。需要说明的是，在不冲突的情况下，本申请的实施例及实施例中的特征可以相互组合。
在下面的描述中阐述了很多具体细节以便于充分理解本申请，但是，本申请还可以采用其他不同于在此描述的其他方式来实施，因此，本申请的保护范围并不受下面公开的具体实施例的限制。
下面参照图1至图25描述根据本申请一些实施例所述无线通信方法、无线通信装置、中继设备、远端设备、基站和可读存储介质。
在本申请的一个实施例中，图1示出了本申请实施例的无线通信方法的流程图之一， 包括：
步骤102，中继设备接收基站的Uu接口的配置参数；
其中，图7示出了本申请实施例的通信场景示意图。新无线(New Radio，NR)或长期演进(Long Term Evolution，LTE)通信系统中远端设备1800与中继设备1700之间通过旁链路1710进行通信，中继设备1700和基站1900之间通过Uu链路1720进行通信。
旁链路运行PC5接口协议。例如，旁链路无线接口控制面有PC5RRC协议，旁链路运行在分组数据汇集协议(Packet Data Convergence Protocol，PDCP)层和无线链路控制(Radio Link Control，RLC)层之上，最下面是介质访问控制(Media Access Control，MAC)层和物理层，旁链路的无线接口用户面自上到下包括服务数据适配协议(Service Data Adaptation Protocol，SDAP)层，PDCP层，RLC层、MAC层和物理层。Uu链路运行Uulink协议。
需要说明的是，本申请涉及的网络通信标准框架，也就是开放式系统互联参考模型(Open System Interconnection Reference Model，OSI)，将整个通信功能划分为七个层次，其中，OSI参考模型的下三层，负责创建网络通信连接的链路，分别是：
物理层(Physical Layer)，用于定义网络的物理结构、传输的电磁标准、Bit流的编码及网络的时间原则，例如，分时复用及分频复用，决定了网络连接类型(端到端或多端连接)及物理拓扑结构。
数据链路层(Data Link Layer)，用于在两个设备上建立数据链路连接，向物理层传输数据信号，并对信号进行处理使之无差错并合理的传输，具体地，数据链路层包括MAC(Media Access Control，介质访问控制)层、RLC(Radio Link Control，无线链路控制)、BMC(Broadcast/Multicast Control，广播/组播通信控制)层和PDCP(Packet Data Convergence Protocol，分组数据汇集协议)层，通过传送信道，MAC层和物理层能够发送和接收数据。
网络层(Network Layer)，用于选择合适的路径，进行阻塞控制等功能，网络层包括用于对控制逻辑信道、传送信道、以及物理信道进行处理的无线资源控制(Radio Resource Control，RRC)层。
具体地，图8示出了本申请实施例的层2中继设备的回传链路控制面协议栈示意图。对于层2旁链路中继设备1700的回传链路，远端设备1800有PC5的RRC连接，用于控制旁链路连接，同时有与基站1900的RRC连接，用于控制与基站1900之间的连接和业务提供。层2旁链路中继设备1700的回传链路不限于图8中给出的Uu的RRC协议栈。图9示出了本申请实施例的层3中继设备的回传链路控制面协议栈示意图。对于层3旁链路中继设备1700的回传链路，远端设备1800仅有与中继设备1700的PC5的RRC连接，没有与基站1900的Uu的RRC连接。其中，回传链路是指远端设备和它的上级的基站进行通信时所使用的无线链路，包括上行传输和下行传输的链路。
步骤104，中继设备根据配置参数确定中继设备对应的小区的时间信息；
具体地，中继设备对应的小区包括：中继设备处于激活态时的服务小区或中继设备处于非激活态的驻留小区。
进一步地，时间信息包括以下至少一种：小区的身份识别信息(小区ID)、Uu接口的系统帧号(System Frame Number，SFN)、Uu接口的时隙号、Uu接口的OFDM(正交频分复用)符号序号、Uu接口的子载波间隔、Uu接口的系统帧号和中继设备的PC5接口 的帧号之间的偏移量。
需要说明的是，一般情况下，不同的子载波间隔有不同的适用频段。例如，在普通CP(循环前缀)下，低频(低于6GHz)数据和控制信道采用的子载波间隔为15KHz和30KHz，而高频数据信道采用的子载波间隔为60KHz和120KHz，不同的子载波间隔下，时隙和符号的长度不同。因此通过子载波间隔能够确定Uu接口的时隙/符号的时间长度。系统帧号为当前承载Uu接口时间信息的发送所在的系统帧号，OFDM符号序号与本次发送相关，例如，开头或结尾。当远端设备建立与中继设备之间的PC5链路，远端设备能够读取到PC5接口的相关参数，例如，PC5接口的时隙号和帧号(Direct Frame Number，DFN)，通过DFN和中继设备的Uu接口的SFN和中继设备的PC5接口的DFN之间的偏移量即可得到Uu接口的系统帧号，而且避免中继设备转发系统消息时，由于Uu接口和PC5接口时间偏移造成的误差。
在本实施例中，依照通信协议的参数或来自小区的配置，中继设备依据从Uu接口获取的跟时间相关的信息生成小区的时间信息，也即旁链路Uu接口的时间信息，该时间信息指示选定的旁链路参考时间位置对应的Uu接口时间信息。一个远端设备在接入一个小区前，需要获得该小区的时间信息。
具体举例来说，对于层2和层3旁链路中继(SL-relay)结构中的远端终端，能够通过时间信息预判中继设备所在小区的SSB发送的可能时间位置和中继设备所在小区的邻小区的SSB发送的可能时间位置，以便于测量和小区重选。对层2旁链路中继结构中的远端终端，能够通过时间信息解析无线资源管理(Radio Resourse Control，RRC)消息中的跟时间相关的配置，例如，测量配置、测量间隙(measurement gap)和测量汇报等。
步骤106，中继设备向远端设备发送携带时间信息的报文。
在本实施例中，在远端设备进行中继通信的过程中，中继设备能够通过旁链路向远端设备提供小区的时间信息。使得处于小区覆盖范围外的远端设备，依然能够通过中继设备发送的时间信息确定小区时间窗或理解测量配置，以便于执行测量间隙配置和小区重选，节约远端设备的测量功率和测量时间，提高远端设备在移动条件下的业务连续性。
具体地，报文中的主信息块(Master Information Block，MIB)的SFN参数来表示系统帧号的高6位，报文中的物理广播信道(PBCH)的信道编码的来表示系统帧号低4位，报文中预先定义SSB发送的时序关系、发送时间位置和序号等，以使远端设备获取系统帧内的时隙号和符号序号。
具体举例来说，对于层2或层3的旁链路中继结构，可以预定义中继设备自动通过旁链路发送旁链路Uu接口时间信息至远端设备，也即远端设备与中继设备建立通信链路后，中继设备便会主动向远端设备提供对应的时间信息。
在本申请的一个实施例中，图2示出了根据本申请实施例的无线通信方法的流程图之二，包括：
步骤202，中继设备确定中继设备的PC5接口的帧号的初始化方式；
步骤204，中继设备根据初始化方式配置PC5接口的帧号。
其中，步骤204具体包括以下两种方式：
方式一，将PC5接口的帧号初始值配置为Uu接口的系统帧号值。
在该实施例中，中继设备通过初始化操作为PC5接口的帧号赋值，将PC5接口的帧号 初始化为与Uu接口系统帧号一样的值。使得远端设备可直接从PC5接口的帧号获得Uu接口系统帧号，从而避免在报文直接传输Uu接口的系统帧号，节省传输资源，提升远端设备的配置效率。
方式二，根据Uu接口的系统帧号与PC5接口的帧号之间的预设偏移量初始化PC5接口的帧号。
在该实施例中，中继设备预先设置Uu接口系统帧号和PC5接口的帧号之间的预设偏移量，也即Uu接口系统帧号和PC5接口的帧号之间的对应关系。根据预设偏移量和Uu接口系统帧号对PC5接口的帧号重新赋值。当远端设备获得PC5接口的帧号和预设偏移量后，即可计算出Uu接口系统帧号。从而避免在报文直接传输Uu接口的系统帧号，节省传输资源，提升远端设备的配置效率。
具体地，对于预设偏移量的获取过程具体包括一下步骤：
中继设备接收对中继设备的第一输入，中继设备响应于第一输入，确定预设偏移量；或中继设备接收基站发送的第一配置信息，中继设备根据第一配置信息确定预设偏移量。
在该实施例中，中继设备可根据用户的操作确定预设偏移量，还可以从基站发送的第一配置信息获得预设偏移量。其中，第一配置信息包括系统信息(SIB)或专用的无线资源管理(RRC)信息。
在本申请的一个实施例中，图3示出了根据本申请实施例的无线通信方法的流程图之三，包括：
步骤302，中继设备将中继设备的PC5接口的子载波间隔配置为Uu接口的子载波间隔。
在该实施例中，由于子载波间隔能够决定时隙/符号的时间长度，为此，可预先设置中继设备的旁链路使用与Uu接口相同的子载波间隔(SubCarrier Sapacing，SCS)，使得PC5接口的时隙号与Uu接口的时隙号相同，PC5接口的帧号与Uu接口的系统帧号相同。远端设备能够直接从PC5接口的帧号和时隙号，获得Uu接口系统帧号和时隙号，从而无需另行传播Uu接口的系统帧号和时隙号，节省传输资源。
在本申请的一个实施例中，中继设备可通过以下形式接收基站的Uu接口的配置参数。
方式一，中继设备读取Uu接口的配置参数。
在该实施例中，在基站与中继设备建立通信链路之后，中继设备通过与基站之间的Uu链路能够读取到Uu接口的配置参数，中继设备通过配置参数即可确定基站小区的时间信息。中继设备再将携带有时间信息的报文发送至远端设备，从而能够为小区覆盖范围外的远端设备提供转却的时间信息，以便于远端设备根据时间信息执行测量间隙配置和小区重选操作，有效降低对小区覆盖范围的局限性，保证远端设备的业务连续性。
具体举例来说，对于层3旁链路中继结构，中继设备能够读取到Uu接口的相关参数，再通过PC5无线资源管理(RRC)或PC5介质访问控制控制元素(MAC CE)通知远端设备，使得远端设备得到时间信息。
方式二，中继设备接收基站发送的Uu接口的配置参数。
在该实施例中，在基站与中继设备建立通信链路之后，基站主动发送Uu接口的配置参数给中继设备。中继设备接收到配置参数后，通过配置参数生成包含对应的时间信息的报文，以将时间信息转发至远端设备。使得远端设备能够根据时间信息执行测量间隙配置 和小区重选操作，有效降低远端设备对小区覆盖范围的局限性，保证远端设备的业务连续性。
具体举例来说，对于层2旁链路中继结构，由于中继设备没有与基站之间的Uu的RRC连接，但远端设备具有与基站之间的Uu的RRC连接，所以基站可以把小区的时间信息，以RRC信令的形式通过中继设备转发给远端设备，远端设备基于接收的RRC信令得到时间信息。
在本申请的一个实施例中，图4示出了本申请实施例的无线通信方法的流程图之四，步骤106，具体包括：
步骤402，中继设备向基站发送时间信息的第一请求信息；
其中，第一请求信息包含远端设备和中继设备的用户信息等。
步骤404，中继设备根据基站返回的第二配置信息发送报文至远端设备。
其中，第二配置信息包括以下至少一种：时间配置消息、许可信息、拒绝信息；时间配置消息包括与远端设备相关的时间配置参数。例如，若基站确认配置，则第二配置信息包括时间配置消息和许可信息；若基站拒绝配置，则第二配置信息包括拒绝信息。
在该实施例中，中继设备在向远端设备发送携带有时间信息的报文之前，先发送关于时间信息的第一请求信息至对应的基站，以询问基站是否远端设备提供时间信息。若基站确认配置，则会反馈配置的许可信息。中继设备根据基站返回的许可信息执行向远端设备进行发送。若基站拒绝配置，则会反馈配置的拒绝信息。中继设备根据基站返回的拒绝信息则不会发送时间信息至远端设备。从而能够通过第一请求信息进一步设置远端设备的接入权限，提高通信系统的安全性。
具体举例来说，对于层3的旁链路中继结构，中继设备具有与基站的RRC连接信道。中继设备可预定义为在收到来自服务基站的许可配置后才通过旁链路发送Uu接口时间信息。进一步地，基站可以使用专用RRC信令或系统消息发送相关配置。
在本申请的一个实施例中，图5示出了本申请实施例的无线通信方法的流程图之五，步骤106，具体包括：
步骤502，中继设备接收远端设备发送的时间信息的第二请求信息；
步骤504，中继设备根据第二请求信息发送报文至远端设备。
其中，第二请求信息包含有远端设备的用户信息和所需的时间信息。
在该实施例中，当远端设备需要接入小区前，至少需要获得该小区的时间信息，便于测量和小区重选。此时，远端设备可发送的时间信息的第二请求信息至中继设备。中继设备在接收到该第二请求信息后，才会将携带有时间信息的报文发送至远端设备。从而避免中继设备持续向远端设备发送时间信息导致的资源占用问题，有利于传输资源分配，提高通信效率和稳定性。
在本申请的一个实施例中，图6示出了本申请实施例的无线通信方法的流程图之六，步骤106，具体包括：
步骤602，中继设备确定报文的传播方式；
其中，传播方式包括单播方式或广播方式。
步骤604，中继设备根据传播方式发送报文至远端设备。
在该实施例中，在收到远端设备发送的第二请求信息后，中继设备可在针对该远端的 响应信息中向远端设备发送报文，以可以周期性地广播发送报文。
具体地，中继设备向远端设备广播发送携带时间信息的报文之前，中继设备接收到网络设备发送的第三配置信息，根据第三配置信息配置广播消息识别符。也即网络设备为中继设备和远端设备配置独立广播消息识别符，以进行Uu接口时间信息的广播发送。
在本申请的一个实施例中，报文包括以下至少一种：旁链路主信息块(sidelink master information block，SL-MIB)、旁链路信令无线承载(sidelink signalling radio bearers，SL-SRB)、发现信号。
其中，旁链路管理信息包括时间信息的更新指示信息，更新指示信息用于远端设备确定时间信息。在该实施例中，当中继设备在SL-MIB消息中指示是否有Uu接口时间更新。如果更新指示信息指示有另外的Uu接口时间消息，则远端设备将接收另外的Uu接口时间消息以确定Uu接口的时间信息。如果更新指示信息指示没有另外的Uu接口时间消息，那么远端设备从SL-MIB消息中获取本次SL-MIB消息携带的Uu接口时间信息。从而能够使远端设备根据更新指示信息接收最新的时间信息。
具体地，在SL-MIB消息中可用一位保留比特作为更新指示信息；
具体举例来说，基于3GPP通信协议的车辆数据传输方案，v2x(Vehicle to X，车到特定目标通信)SL-MIB包含有时隙号，只需要将除时隙号以外的时间信息放入SL-MIB中即可。

在本申请的一个实施例中，小区包括以下至少一种：主小区、辅小区、主辅小区。
在该实施例中，在载波聚合(Carrier Aggregation，CA)中，聚合了两个或更多个分量载波(Component Carrier，CC)，以便于支持高达100MHz的更宽的传输带宽。当用户设备为单连接状态，用户设备进入连接态后可以同时通过多个分量载波与基站进行通信，基站会通过显式的配置或者按照协议约定为用户设备指定一个主分量载波(Primary Component Carrier，PCC)，其他的分量载波称为辅分量载波(Secondary Component Carrier，SCC)，在主分量载波上的小区称为主小区(Primary Cell，Pcell)，也即工作在主频带上的小区。在辅分量载波上的小区称为辅小区(Secondary Cell，Scell)，也即工作在辅频带上的小区。当用户设备为双连接(Dual connectivity，DC)状态，则网络中部署了多个小区，也即MCG(Master Cell group，主小区组)和SCG(Secondary Cell group，辅小区组)，SCG中主分量载波上的小区称为主辅小区(Primary Secondary cell，PScell)，辅分量载波上的小区称为辅小区。用户设备可根据需求可得到不同小区的时间信息。
其中，可预定义中继设备在旁链路至少发送其PCell的Uu接口时间信息。
具体地，中继设备配置为单连接，主小区和辅小区载波聚合联合在一起，且PC5链路使用辅小区的资源时，中继设备根据配置参数确定主小区和/或辅小区的时间信息，并发送至远端设备。中继设备配置为双连接，中继设备根据配置参数确定主小区和/或主辅小区的时间信息，并发送至远端设备。例如，当中继设备处于EN-DC连接态时，仅在旁链路发送PSCell的Uu接口时间信息。
具体举例来说，中继设备依照协议预定义或来自小区的配置，从Uu接口获取的跟时间相关的信息，生成Uu接口的时间信息，并将时间信息通过旁链路发送给远端设备。
其中，该时间信息包括如下内容一项或多项：小区ID、系统帧号、时隙号和OFDM符号序号；可选地，Uu接口时间信息还包含该小区Uu接口对应的SCS信息，以帮助远端设备确定Uu接口一个时隙/符号的时间长度。旁链路Uu接口时间信息指示选定的旁链路参考时间位置对应的Uu接口时间信息。其中小区ID是目前中继设备的一个小区ID，系统帧号是当前承载Uu接口时间信息的发送所在的系统帧号，OFDM符号序号是基于本次发送对应的帧，例如，开头或结尾。
具体地，对于层2旁链路中继结构，基站把PCell/PSCell的Uu接口的SFN跟中继设备的PC5接口的DFN之间的偏移量通过RRC信令发给远端设备，远端设备基于从PC5接口收到的DFN和该偏移量来计算中继设备的小区的SFN。作为另一种方式，对于层2或层3旁链路中继结构，中继设备把PCell/PSCell的Uu接口的SFN跟中继设备的PC5接口的DFN之间的偏移量通过PC5 RRC或PC5 MAC Control Element(控制元件)来通知远端设备被，远端设备基于从PC5接口收到的DFN和该偏移来计算中继设备的小区PCell/PSCell的SFN。
可选地，旁链路Uu接口时间信息可以通过如下方法之一向远端设备发送：
1.时间信息放到SL-MIB中向远端设备发送，具体地，若当前v2xSL-MIB中已有时隙号，可进一步包含Uu接口系统帧号；或把上述偏移量包含到SL-MIB消息中进行广播。
2.使用SL-SRB向远端设备发送，例如SL-SRB0、1、2、3中的任意一个；当然也可以定义一个新的SL-SRB，用于旁链路Uu接口时间信息发送。
3.作为旁链路发现信号携带信息的一部分，向远端设备发送。
可选地，在收到远端设备请求后，中继设备可在响应信息中向远端设备发送该时间信息，或周期性地广播发送。
可选地，对于层2或层3旁链路中继结构，可以预定义中继设备在旁链路发送旁链路Uu接口时间信息，使得远端设备与中继设备连接后即可得到中继设备发送的时间信息。
可选地，对于层3结构的旁链路中继，中继设备只有在收到来自基站的许可配置后才在旁链路发送旁链路Uu接口时间信息。基站可以使用专用RRC信令或系统消息发送相关配置。
可选地，可以预定义中继设备在初始化DFN时，将DFN初始化为跟Uu接口帧号一样的值，使得远端设备能够直接从DFN获得Uu接口系统帧号，从而不用另行广播Uu接口的系统帧号。作为另一种方式，可预定义中继设备的旁链路使用与Uu接口相同的SCS，这样PC5接口的时隙号与Uu接口的时隙号相同，远端设备直接从DFN就能够获得Uu接口系统帧号，同样不需要另行广播Uu接口的系统帧号和时隙号。
可选地，当中继设备在SL-MIB消息中指示是否有Uu接口时间指示信息发送，例如，用一位保留比特进行指示。如果指示有另外的Uu接口时间消息，则远端设备需收取此Uu接口时间消息以确定Uu接口的时间；如果指示没有另外的Uu接口时间消息，那么远端设备从SL-MIB消息得出Uu接口时间信息。
可选地，可预定义中继设备在旁链路至少发送其PCell的Uu接口时间信息。
具体地，当中继设备配置单连接，且配有载波聚合，PC5链路使用的时辅小区的资源 时，基站可配置中继设备在旁链路发送PCell的时间信息或辅小区的Uu接口的时间信息。
当中继设备配置了双连接，则可以在旁链路发送PCell和/或PSCell的Uu接口时间信息。例如，当中继设备处于EN-DC连接态时，仅在旁链路发送PSCell的Uu接口时间信息。
