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。
在相关技术中，网络侧设备在系统消息(SIB12)中会携带有频率列表，该频率列表中的每个元素为对应频率上的Sidelink资源配置。其中，Sidelink资源配置包括频率所在位置、Sidelink发送资源池以及Sidelink接收资源池。但是，该频率列表中的频率资源只有授权频率上的频率资源。
为了扩展Sidelink可用的频率资源，本公开提出一种通信方法，该方法包括终端确定在非授权频率上的目标Sidelink资源，并在该目标Sidelink资源进行Sidelink通信。
图1是根据一些实施例示出的一种通信方法的网络系统的结构图。如图1所示，包括第一终端11、第二终端12以及网络侧设备13。其中，第一终端11和第二终端12之间可以通过PC5接口并使用Sidelink通信。网络侧设备13与终端(包括第一终端11和第二终端12)之间可以通过空口(Uu)接口并使用上下行链路(uplink and downlink)进行通信。
其中，第一终端11和第二终端12是用户终端(User Equipment，UE)或者其他终端侧设备，例如：手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(Personal Digital Assistant，PDA)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)、智能汽车、车载设备或者机器人等终端侧设备。值得说明的是，在本公开中，并不限定终端的具体类型。
网络侧设备可以是基站，基站是一种部署在接入网中用于为终端提供无线通信功能的装置。该基站既可以是终端的服务小区的基站，也可以是终端的服务小区相邻小区的基站。基站可以包括各种形式的宏基站，微基站，中继站，接入点、发送接收点(Transmission Reception Point，TRP)等等。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同，在5G新空口(NR，New Radio)系统中，称为gNodeB或者gNB。随着通信技术的演进，“基站”这一名称可能描述会变化。网络侧设备也可以是定位管理功能实体(Location Management Function，LMF)。
值得说明的是，在图1所示的网络系统中，第一终端11和第二终端12通过Sidelink直连链路通信。在另一些实施方式中，第一终端11和第二终端12也可以通过Sidelink间接链路通信。即第一终端11和第二终端12通过至少一个中继终端通信。
图2是根据一些实施例示出的一种通信方法的流程图。如图2所示，该通信方法可以用于终端中，包括以下步骤。
在步骤210中，确定在非授权频率上的目标Sidelink资源。
这里，Sidelink资源可以包括Sidelink发送资源和/或Sidelink接收资源。目标Sidelink资源可以是在非授权频率上的至少一个Sidelink发送资源和/或Sidelink接收资源。
目标Sidelink资源可以是终端能够使用的非授权频率上的Sidelink资源，和/或，网络侧设备能够支持的在非授权频率上的Sidelink资源。其中，当终端在授权频率上的带宽受限时，终端可以确定至少一个在非授权频率上的Sidelink资源作为目标Sidelink资源。
值得说明的是，在非授权频率上的目标Sidelink资源可以是终端向网络侧设备请求的，和/或，终端自行确定的。
在步骤220中，在所述目标Sidelink资源上进行Sidelink通信。
这里，目标Sidelink资源是用于Sidelink通信的资源，即该目标Sidelink资源用于Sidelink通信的Sidelink发送资源和/或Sidelink接收资源。
基于目标Sidelink资源，终端可以使用该目标Sidelink资源与目的终端进行Sidelink通信。其中，Sidelink通信可以是通过Sidelink直连链路通信，或者是通过Sidelink间接链路进行通信。Sidelink直连链路通信是指两个终端不通过中继终端，直接进行Sidelink通信，Sidelink间接链路是指两个终端之间通过至少一个中继终端进行Sidelink通信。
由此，终端通过确定在非授权频率上的目标Sidelink资源，并在该目标Sidelink资源上进行Sidelink通信，可以拓展Sidelink可用的频率资源，以提供大带宽、低延时的Sidelink通信链路。
图3是根据另一些实施例示出的一种通信方法的流程图。如图3所示，该通信方法可以用于终端中，包括以下步骤。
在步骤310中，向网络侧设备发送第一资源请求，其中，所述第一资源请求用于请求所述网络侧设备为所述终端分配在非授权频率上的Sidelink资源。
这里，终端可以向网络侧设备发送第一资源请求，该第一资源请求用于请求网络侧设备为终端分配在非授权频率上的Sidelink资源。其中，关于Sidelink资源的相关描述可以参照图2所示的实施例中关于步骤210的描述，在此不再赘述。
在一些实施例中，第一资源请求可以通过SidelinkUEInformation消息携带。
其中，当终端处于连接态时，终端可以向网络侧设备发送第一资源请求，网络侧设备响应于该第一资源请求，根据第一预设规则为终端分配在非授权频率上的Sidelink资源。
值得说明的是，网络侧设备根据第一预设规则为终端分配在非授权频率上的Sidelink资源可以是指网络侧设备从其能够支持的非授权频率中，确定至少一个非授权频率，并在该至少一个非授权频率中确定至少一个Sidelink资源，并将该至少一个Sidelink资源分配给终端。网络侧设备分配在非授权频率上的Sidelink资源可以是动态的，即可以根据网络侧设备能够支持的在非授权频率上的Sidelink资源，动态选取至少一个Sidelink资源分配给终端。
在步骤320中，将所述网络侧设备分配的Sidelink资源确定为所述目标Sidelink资源。
这里，终端响应于网络侧设备发送的Sidelink资源分配信息，将网络侧设备分配的在非授权频率上的Sidelink资源确定为目标Sidelink资源。其中，该Sidelink资源分配信息携带有网络侧设备分配的在非授权频率上的Sidelink资源。
在步骤330中，在所述目标Sidelink资源上进行Sidelink通信。
这里，目标Sidelink资源是用于Sidelink通信的资源，即该目标Sidelink资源用于Sidelink通信的Sidelink发送资源和/或Sidelink接收资源。
基于目标Sidelink资源，终端可以使用该目标Sidelink资源与目的终端进行Sidelink通信。其中，Sidelink通信可以是通过Sidelink直连链路通信，或者是通过Sidelink间接链路进行通信。Sidelink直连链路通信是指两个终端不通过中继终端，直接进行Sidelink通信，Sidelink间接链路是指两个终端之间通过至少一个中继终端进行Sidelink通信。
图4是根据一些实施例示出的一种通信方法的通信时序图。如图4所示，终端向网络侧设备发送第一资源请求，网络侧设备响应于该第一资源请求，为终端分配在非授权频率上的Sidelink资源，其中，网络侧设备可以响应于第一资源请求，从其能够支持的非授权频率中，确定至少一个非授权频率，并在该至少一个非授权频率中确定至少一个Sidelink资源。网络侧设备向终端发送Sidelink资源分配信息，终端接收该Sidelink资源分配信息，获得目标Sidelink资源。其中，在Sidelink资源分配信息上携带有网络侧设备分配的在非授权频率上的Sidelink资源。
由此，终端通过向网络侧设备发送第一资源请求，以使网络侧设备响应于该第一资源请求，为终端分配在非授权频率上的Sidelink资源，终端将网络侧设备分配的在非授权频率上的Sidelink资源确定为用于Sidelink通信的目标Sidelink资源，以在该目标Sidelink资源上进行Sidelink通信，可以拓展Sidelink可用的频率资源，以提供大带宽、低延时的Sidelink通信链路。
在一些实施例中，第一资源请求可以包括以下至少一种：
第一目的终端标识；第一逻辑信道标识；第一非授权频率标识。
其中，所述第一目的终端标识用于指示目的终端的数据发送频率为在非授权频率上的Sidelink资源；所述第一逻辑信道标识用于指示逻辑信道的数据发送频率为在非授权频率上的Sidelink资源；所述第一非授权频率标识用于指示所述终端请求的Sidelink资源在非授权频率上。
值得说明的是，目的终端是指与终端进行Sidelink通信的对端终端。如图1所示，第二终端12为第一终端11的目的终端。通过在第一资源请求中携带第一目标终端标识，可以指示目的终端在Sidelink通信中使用的数据发送频率为在非授权频率上的Sidelink资源。通过在第一资源请求中携带第一逻辑信道标识，可以指示在Sidelink通信中逻辑信道的数据发送频率为在非授权频率上的Sidelink资源。第一非授权频率标识用于指示终端向网络侧设备请求的Sidelink资源在非授权频率上。通过在第一资源请求中携带第一非授权标识，网络侧设备可以知道终端将要请求在非授权频率上的Sidelink资源，网络侧设备根据该第一非授权标识，为终端分配在非授权频率上的Sidelink资源。
图5是根据又一些实施例示出的一种通信方法的流程图。如图5所示，该通信方法可以用于终端中，包括以下步骤。
步骤510，判断网络侧设备是否向终端发送频率配置信息；
步骤520，在网络侧设备已发送频率配置信息的情况下，判断终端是否处于连接态；
步骤530，在终端处于连接态的情况下，向网络侧设备发送第一资源请求；
步骤540，将网络侧设备分配的在非授权频率上的Sidelink资源确定为目标Sidelink资源；
步骤550，在目标Sidelink资源上进行Sidelink通信。
这里，在步骤510中，终端可以请求网络侧设备向终端发送频率配置信息，或者接收网络侧设备广播的频率配置信息。终端判断网络侧设备是否向终端发送频率配置信息的判断结果，可以根据终端是否接收到频率配置信息来确定。当终端接收到频率配置信息时，确定网络侧设备已发送频率配置信息，当终端未接收到频率配置信息时，确定网络侧设备未发送频率配置信息。
其中，频率配置信息用于使终端确定用于Sidelink通信的在非授权频率上的目标Sidelink资源。
在一些实施例中，可以根据网络侧设备发送的系统消息，获得所述频率配置信息。其中，在网络侧设备发送的系统消息中携带有频率配置信息。
在一些实施例中，可以根据网络侧设备发送的RRC重配消息，获得所述频率配置信 息。其中，在网络侧设备发送的RRC重配消息中携带有频率配置信息。
在一些实施例中，可以根据中继终端发送的RRC重配消息，获得所述频率配置信息，其中，该RRC重配消息是网络侧设备向所述中继终端发送的。应当理解的是，网络侧设备向中继终端发送的RRC重配消息，中继终端将该RRC重配消息转发至终端。在该RRC消息中携带有频率配置信息。其中，RRC重配消息可以是Sidelink RRC重配消息。
其中，频率配置信息是用于终端请求非授权频率的信息。在一些实施例中，所述频率配置信息包括以下至少一种：
第一频率列表；第二频率列表；CAPC配置信息；LBT配置信息。
其中，所述第一频率列表包括授权频率以及非授权频率，且在所述第一频率列表中通过非授权频率标识标记所述非授权频率。所述第二频率列表包括非授权频率。所述CAPC配置信息包括Sidelink逻辑信道的信道接入优先级和/或QoS标识符与信道接入优先级之间的映射关系。所述LBT配置信息包括触发持续的LBT失败事件的最大LBT失败次数。
这里，在第一频率列表中可以包括网络侧设备能够支持的授权频率以及非授权频率。在第一频率列表中，可以通过非授权频率标识对非授权频率进行标记，以区分第一频率列表中的非授权频率以及授权频率。例如，针对在第一频率列表中的非授权频率，可以携带有类似于“非授权”的非授权频率标识。
当然，在另一些实施方式中，非授权频率标识可以为CAPC配置信息和/或LBT配置信息。即在第一频率列表中，通过该非授权频率对应的CAPC配置信息和/或LBT配置信息对第一频率列表中的非授权频率进行标记。
应当理解的是，在第一频率列表中的授权频率以及非授权频率均可以是用于Sidelink通信的频率资源，该频率资源可以包括：目的终端的Sidelink目的地址、传输方式、QoS(Quality of Service，服务质量)、数据发送频率以及数据接收频率中的至少一种。其中，传输方式可以包括单播、多播以及广播中的一种。
在第二频率列表中包括网络侧设备能够支持的非授权频率。其中，在第二频率列表中的非授权频率均可以是用于Sidelink通信的非授权频率，该非授权频率可以包括：目的终端的Sidelink目的地址、传输方式、QoS(Quality of Service，服务质量)、数据发送频率以及数据接收频率中的至少一种。其中，传输方式可以包括单播、多播以及广播中的一种。
CAPC(Channel Access Priority Class，信道接入优先级)配置信息包括Sidelink逻辑信道的信道接入优先级和/或QoS标识符与信道接入优先级之间的映射关系。其中，QoS标识符用于指示对应的QoS标准值，例如，在5G通信技术中，QoS标识符可以为5QI，则映射关系可以为5QI与CAPC之间的映射关系。
值得说明的是，当终端在非授权频率上进行信道接入时，需要根据信道接入优先级来判断是否能够接入，该信道接入优先级是根据待发送数据的逻辑信道的优先级确定的。因此，通过CAPC配置信息，可以获得Sidelink逻辑信道的信道接入优先级和/或QoS标识符与信道接入优先级之间的映射关系，从而在进行信道接入时，能够确定到对应的信道接入优先级。
LBT(Listen Before Talk，先听后说)配置信息包括触发持续的LBT失败事件的最大LBT失败次数。其中，终端在非授权频率上进行Sidelink发送时，需要进行LBT机制，避免产生干扰，同时兼顾不同终端之间的公平性。在LBT成功之后，终端使用非授权频率进行Sidelink发送。通过LBT配置信息，终端可以在非授权频率上进行LBT机制。
在另一些实施例中，第一频率列表中的非授权频率标识可以包括CAPC配置信息和/或LBT配置信息。即在第一频率列表中，通过CAPC配置信息和/或LBT配置信息对非授权频率进行标记。
值得说明的是，在步骤520中，当终端接收到频率配置信息时，表征网络侧设备支持 向终端分配用于Sidelink通信的在非授权频率上的Sidelink资源。当终端未接收到频率配置信息时，表征网络侧设备不支持向终端分配用于Sidelink通信的在非授权频率上的Sidelink资源。
在步骤520中，在网络侧设备已发送频率配置信息的情况下，终端进一步判断终端是否处于连接态。在步骤530中，在终端处于连接态的情况下，终端向网络侧设备发送用于请求网络侧设备为终端分配在非授权频率上的Sidelink资源的第一资源请求，以使网络侧设备响应于第一资源请求，根据第一预设规则为终端分配在非授权频率上的Sidelink资源。在一些实施例中，第一资源请求可以通过SidelinkUEInformation消息携带。其中，关于网络侧设备如何根据第一预设规则为终端分配在非授权频率上的Sidelink资源，可以参考图3所示实施例中关于步骤310的相关描述，在此不再赘述。
在步骤540中，终端响应于网络侧设备发送的Sidelink资源分配信息，将网络侧设备分配的非授权频率资源确定为目标非授权频率资源。其中，该分配信息是网络侧设备发送的用于为终端分配非授权频率资源的信息。
在步骤550中，终端响应于网络侧设备发送的Sidelink资源分配信息，将网络侧设备分配的在非授权频率上的Sidelink资源确定为目标Sidelink资源。其中，该Sidelink资源分配信息携带有网络侧设备分配的在非授权频率上的Sidelink资源。
基于目标Sidelink资源，终端可以使用该目标Sidelink资源与目的终端进行Sidelink通信。其中，Sidelink通信可以是通过Sidelink直连链路通信，或者是通过Sidelink间接链路进行通信。Sidelink直连链路通信是指两个终端不通过中继终端，直接进行Sidelink通信，Sidelink间接链路是指两个终端之间通过至少一个中继终端进行Sidelink通信。
由此，在网络侧设备已向终端发送频率配置信息的情况下，若终端处于连接态，则终端向网络侧设备发送第一资源请求，以使网络侧设备响应于该第一资源请求，为终端分配在非授权频率上的Sidelink资源，终端将网络侧设备分配的在非授权频率上的Sidelink资源确定为用于Sidelink通信的目标Sidelink资源，以在该目标Sidelink资源上进行Sidelink通信，可以拓展Sidelink可用的频率资源，以提供大带宽、低延时的Sidelink通信链路。

终端可以根据第二预设规则从第一资源池中选取至少一个Sidelink资源作为目标Sidelink资源。
值得说明的是，当终端处于空闲态或者非激活态时，由于终端与网络侧设备之间不通信，此时，终端可以从第一资源池中确定在非授权频率上的目标Sidelink资源。

由此，终端通过在第一资源池中，确定用于Sidelink通信的目标Sidelink资源，以在 该目标Sidelink资源上进行Sidelink通信，不仅可以拓展Sidelink可用的频率资源，以提供大带宽、低延时的Sidelink通信链路，而且，即使终端处于空闲态或者非激活态，终端也能够请求到在非授权频率上的目标Sidelink资源。

这里，终端可以接收网络侧设备发送的系统消息，在该系统消息中携带有第一资源池，终端根据该系统消息，获得第一资源池。其中，第一资源池包括至少一个候选的在非授权频率上的Sidelink资源。
应当理解的是，该系统消息不一定是终端在请求Sidelink资源时是由网络侧设备发送的。该系统消息可以是终端与网络侧设备通信时，由网络侧设备向终端广播的。即终端设备与网络侧设备通信，则网络侧设备向终端广播最新的第一资源池。当终端处于空闲态或者非激活态时，在终端上也存储有第一资源池。
在步骤720中，从网络侧设备下发的第一资源池中确定目标Sidelink资源。

这里，关于步骤1510执行的方法可以参照图5所示的实施例中关于步骤510的相关描述，在此不再赘述。关于频率配置信息的相关内容也可以参照图5所示的实施例中关于步骤510的相关描述，在此不再赘述。关于步骤1520执行的方法可以参照图5所示的实施例中关于步骤520的相关描述，在此不再赘述。关于Sidelink资源的相关描述可以参照图2所示的实施例中关于步骤210的描述，在此不再赘述。
其中，频率配置信息用于使终端确定用于Sidelink通信的在非授权频率上的目标Sidelink资源。
值得说明的是，在一些实施例中，可以根据网络侧设备发送的系统消息，获得所述频率配置信息。其中，在网络侧设备发送的系统消息中携带有频率配置信息。在一些实施例中，可以根据网络侧设备发送的RRC重配消息，获得所述频率配置信息。其中，在网络侧设备发送的RRC重配消息中携带有频率配置信息。在一些实施例中，可以根据中继终端发送的RRC重配消息，获得所述频率配置信息，其中，该RRC重配消息是网络侧设备向所述中继终端发送的。应当理解的是，网络侧设备向中继终端发送的RRC重配消息，中继终端将该RRC重配消息转发至终端。在该RRC消息中携带有频率配置信息。其中，RRC重配消息可以是Sidelink RRC重配消息。
在步骤1530中，在终端处于连接态的情况下，进一步判断终端将要请求的指定非授权频率是否在频率配置信息中。其中，当终端将要请求的指定非授权频率在第一频率列表和/或第二频率列表中时，确定终端将要请求的指定非授权频率在频率配置信息中。则终端向网络侧设备发送用于请求网络侧设备为终端分配在指定非授权频率上的Sidelink资源的第二资源请求，以使网络侧设备响应于第二资源请求，为终端分配在指定非授权频率上的Sidelink资源作为终端的目标Sidelink资源。
在一些实施例中，第二资源请求可以通过SidelinkUEInformation消息携带。
值得说明的是，该第二资源请求携带有由终端指定的指定非授权频率。该指定非授权频率可以是终端在第一频率列表和/或第二频率列表中确定的。例如，终端可以根据第四预设规则在第一频率列表和/或第二频率列表中，选取至少一个非授权频率作为指定非授权频率。
在一些实施例中，所述第二资源请求包括以下至少一种：
第二目的终端标识；第二逻辑信道标识；发送频率标识；第二非授权频率标识。
值得说明的是，关于第二目的终端标识、第二逻辑信道标识、发送频率标识以及第二非授权频率标识的含义可以参照图14所示的实施例中关于步骤1430中的相关描述，在此不再赘述。
在步骤1540中，终端将网络侧设备分配的在指定非授权频率上的Sidelink资源确定为目标Sidelink资源。在步骤1550中，目标Sidelink资源是用于Sidelink通信的资源，即该目标Sidelink资源用于Sidelink通信的Sidelink发送资源和/或Sidelink接收资源。
基于目标Sidelink资源，终端可以使用该目标Sidelink资源与目的终端进行Sidelink通信。其中，Sidelink通信可以是通过Sidelink直连链路通信，或者是通过Sidelink间接链路进行通信。Sidelink直连链路通信是指两个终端不通过中继终端，直接进行Sidelink通信，Sidelink间接链路是指两个终端之间通过至少一个中继终端进行Sidelink通信。
由此，在网络侧设备已向终端发送频率配置信息的情况下，若终端处于连接态，终端可以在网络侧设备下发的频率配置信息中确定指定非授权频率，并向网络侧设备发送第二资源请求，以使网络侧设备响应于该第二资源请求，为终端分配在该指定非授权频率上的Sidelink资源，终端将网络侧设备分配的在该指定非授权频率上的Sidelink资源确定为用于Sidelink通信的目标Sidelink资源，以在该目标Sidelink资源上进行Sidelink通信。能够实现由终端自主选择用于Sidelink通信的在非授权频率上的目标Sidelink资源，以拓展Sidelink可用的频率资源，以提供大带宽、低延时的Sidelink通信链路。

值得说明的是，当终端处于空闲态或者非激活态时，由于终端与网络侧设备之间不通信，此时，若终端将要请求的非授权频率在频率配置信息的第一频率列表和/或第二频率列表中，则终端可以从第三资源池中确定在非授权频率上的目标Sidelink资源。

由此，终端通过根据频率配置信息以及第三资源池，确定用于Sidelink通信的在非授权频率上的Sidelink资源，以在该目标Sidelink资源上进行Sidelink通信，不仅可以拓展Sidelink可用的频率资源，以提供大带宽、低延时的Sidelink通信链路，而且，即使终端处于空闲态或者非激活态，终端也能够请求到在非授权频率上的目标Sidelink资源。
