图1是根据一示例性实施例示出的一种资源选择方法的流程图,如图1所示,该资源选择方法可以应用于至用户设备中,该用户设备可以为上述的远端UE,该方法包括以下步骤。
在步骤S101中,响应于接收到的系统信息中不存在发送资源池,使用预配置的发送资源进行侧行链路发送。
示例地,为支持UE与UE之间的直接通信,本实施例中各个设备之间通过5G(第五代移动通信系统)、4G(第五代移动通信系统)通信技术建立数据通信,基于sidelink(侧行链路,SL)通信方式,UE与UE之间可以通过PC-5接口进行直接通信。根据UE与UE之间的对应关系,在sidelink上支持单播、组播和广播三种方式。发送UE在PSCCH(Physical Sidelink Control Channel,物理控制信道)上发送sidelink控制信息SCI(Sidelink Control Information,侧链控制信息),以及在PSSCH(Physical Sidelink Shared Channel,物理共享信道)上发送第二阶段SCI,其中SCI携带传输数据的资源位置、源UE标识和目的UE标识等;接收UE在收到SCI后,根据其中的源UE标识和目的UE标识确定是否接收对应的数据以及对应哪个进程。在单播连接中,每个UE都对应一个目的标识,在组播中,每个UE可以属于一个或多个组,每个组与一个目的标识相对应,在广播中,所有UE都至少与一个目的标识相对应。
Sidelink通信有两种发送资源分配方式,一种是网络动态调度的方式,另一种是UE在基站广播的资源池中自主选择的方式。
其中,网络动态调度的方式是基站根据UE的缓存数据上报,动态给UE分配Sidelink上的发送资源,UE可以为被基站网络覆盖的中继UE。
而自主选择是UE自行地从系统信息中的发送资源池或者预配置的发送资源或RRC(Radio Resource Control,无线资源控制)重配消息中的发送资源中随机选择发送资源。对于系统信息 而言,基站可以将系统信息发送给远端UE。示例地,基站可以根据网络中是否具有资源池以及具有哪些资源池,来依据这些信息生成系统信息;基站再将这些系统信息进行广播,被基站网络覆盖的UE获取系统信息,这些UE可以作为中继UE将系统信息转发给远端UE,远端UE处于空闲态或非激活态时,可以使用基站广播的系统信息中的发送资源池来进行侧行链路发送;对于RRC重配消息而言,RRC重配消息是基站根据UE上报的资源请求后所生成的消息,该消息中携带有基站返回给UE的发送资源,UE进入连接态时,UE可以使用重配消息中的发送资源来进行侧行链路发送;预配置的发送资源是预先在远端UE配置的发送资源,UE处于脱网状态时,UE可以使用预配置的发送资源来进行侧行链路发送,脱网状态包括UE未被基站网络覆盖。
其中,系统信息的发送资源与RRC重配消息均是基站发出的,预配置的发送资源池是在UE事先配置的,系统信息可以是SIB12。
值得说明的是,RRC重配消息中的发送资源可以为发送资源池,UE可以从发送资源池中选择至少一个发送资源来进行侧行链路发送;预配置的发送资源可以为预配置的发送资源池,UE可以从预配置的发送资源池中选择至少一个发送资源来进行侧行链路发送。
值得说明的是,发送资源池可以为中继侧行链路发送资源池,发送资源可以为中继侧行链路发送资源,中继侧行链路包括远端UE、中继UE与基站,远端UE与基站之间通过中继UE进行交互。中继侧行链路发送资源为sidelink发送资源,中继侧行链路发送资源池为sidelink发送资源池。
sidelink发送资源为时间域和频率域的资源参数,各个基站可以通过时间域从sidelink发送资源池中调度对应时间周期的sidelink发送资源,通过频率域从sidelink发送资源池中确定对应的sidelink发送资源,来满足UE的资源请求。示例的,以4G通信技术为例,4G基站通过DCI(Downlink Control Information,下行控制信息)调度sidelink发送资源池中的sidelink发送资源,其中,设定DCI中携带的时间域为10点-11点,频率域为1880MHz-1900MHz,则UE根据该DCI确定在10点-11点周期内,频域段1880MHz-1900MHz的sidelink发送资源来作为UE发送资源请求的反馈。
网络动态调度方式的资源池和自主选择方式的资源池是分开的,网络动态调度由基站统一分配发送资源,因此可以通过合理的算法,避免不同UE进行碰撞。
基站可以在系统信息中携带发送资源池,UE使用系统信息中的发送资源池进行自主选择。系统信息中的发送资源池分为两种,一种为一般发送资源池(sl-TxPoolSelectedNormal),另一种为特殊发送资源池(sl-TxPoolExceptional)。如果系统信息中携带一般发送资源池,UE使用一般发送资源池;如果系统信息中没有携带一般发送资源池,则UE使用特殊发送资源池,如果系统信息中没有携带任何发送资源池,则UE需要使用预配置的发送资源进行侧行链路发送。
值得说明的是,进行侧行链路发送可以为进行sidelink发送,远端UE进行侧行链路发送的过程中,可以携带发送给中继UE或基站的数据或指令,在侧行链路中进行传输。例如在进行侧行链路发送的过程中,可以携带远端UE发送给基站的资源请求,也可以携带基站发送给远端UE的RRC重配消息等。
值得说明的是,本公开任意实施例提出的用户设备可以是手机、平板、便携电脑、带无线收发功能的电脑、虚拟现实(虚拟现实(virtual reality,VR)终端设备、增强现实(augmented reality,AR)终端设备、工业控制(industrial control)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等,本公开对应用场景不做限定,用户设备有时也可以称为终端设备、终端、接入终端、UE单元、UE站、移动设备、移动站、移动台(mobile station)、移动客户端等。
值得说明的是,预配置的发送资源可以由开发人员事先在UE中进行配置,预配置的发送资源为时间域和频率域的资源参数,可以预先在UE中配置发送资源的频域段、时间周期、可用时长与带宽等。
UE可以获取基站广播的系统信息,如此,位于基站网络覆盖范围内的中继UE,可以获取基站广播的系统信息。当远端UE处于脱网状态下,通过预配置的发送资源向中继UE发送系统信息请求后,中继UE可以将获取的基站的系统信息转发给远端UE;远端UE在确定系统信息中未携带有发送资源池的情况下,此时无法进行侧行链路发送,为了能够进行侧行链路发送,可以继续使用预配置的发送资源进行侧行链路发送。
通过上述方案,在系统信息不存在发送资源池的情况下,远端UE可以使用预配置的发送资源,来继续进行侧行链路发送,使得远端UE能够与中继UE或基站进行数据或信令的交互,避免远端UE的通信或业务中断。
图2是根据一示例性实施例示出的一种资源选择方法的流程图,如图2所示,该资源选择方法应用于用户设备中,该方法包括以下步骤。
在步骤S201中,响应于接收到由所述中继设备发送的系统信息不存在所述发送资源池,使用所述预配置的发送资源进行侧行链路发送。
示例地,本实施例应用于用户设备中,该用户设备可以是上述通过中继UE与基站交互的远端UE,远端UE与中继UE之间的通信信号可以采用sidelink单播发送;中继设备可以是中继UE,用于建立远端UE与基站之间的通信连接,中继设备被基站网络覆盖。
示例地,基站可以通过网络广播系统信息,被基站网络覆盖的中继UE可以接收到系统信息,所以远端UE可以响应于中继UE的基站的系统信息中不存在发送资源池,使用预配置的发送资源进行侧行链路发送。远端UE接收中继UE发送的系统信息,可以是中继UE从基站获取的。
值得说明的是,基站网络的覆盖区域为服务小区,中继UE可以从服务小区中获取基站广播的系统信息。服务小区是在通信系统中,基站或基站的一部分所覆盖的区域,在这个区域内的UE之间可以相互通过无线信道进行通信。
值得说明的是,一个UE可以不直接与基站连接而通过另外一个UE的中继实现与基站的通信,其中与基站没有连接的UE称为远端UE(remote UE),提供中继功能的UE称为中继UE(relay UE),远端UE与中继UE之间通过sidelink单播通信,这种架构称为U2N(UE to NW)中继。
远端UE通过中继UE接入网络的过程中,在获取到中继UE转发的系统信息之前,可以使用预配置的发送资源进行侧行链路发送,从而与中继UE交互信令与数据。
示例地,远端UE可以通过预配置的发送资源,向中继UE发送系统信息请求,系统信息请求中携带请求的系统信息标识;中继UE依据系统信息标识确定系统信息,向远端UE返回系统信息。其中,中继UE可以获取基站广播的系统信息。
应当理解,该方法还可以包括:接收系统消息,所述系统消息可以由基站广播。当远端UE被基站网络覆盖时,所述远端UE直接接收基站广播的系统消息;当远端UE未被基站网络覆盖时,也可以由基站发送给中继UE并由所述中继UE转发给所述远端UE,本公开对此不作限制。
通过上述技术方案,远端UE可以接收中继UE从基站获取的系统信息;在确定系统信息中不存在发送资源池的情况下,使用预配置的发送资源进行侧行链路发送,以保障远端UE与中继UE之间的通信连接,避免远端UE的通信和业务中断。
图3是根据一示例性实施例示出的一种资源选择方法的流程图,如图3所示,该资源选择方法应用于用户设备中,该方法包括以下步骤。
在步骤S301中,在所述系统信息中不存在所述发送资源池的情况下,进入连接态。
示例地,在远端UE接收到系统信息,并确定系统信息中不存在发送资源池的情况下,远端UE进入连接态。
其中,远端UE进入连接态表明远端UE需要与中继UE或基站进行数据或信令的交互,且远端UE处于脱网的状态。
在步骤S302中,根据所述预配置的发送资源向基站请求发送资源。
示例地,在远端UE进入连接态后,为了满足远端UE需要与中继UE或基站进行数据或信令的交互需求,远端UE可以采用远端UE中预先配置的发送资源向中继UE发送资源请求,中继UE将资源请求转发至基站。
其中,由于中继UE被基站网络覆盖,所以中继UE可以将远端UE发送的资源请求转发至基站;资源请求用于向基站请求发送资源,以使得远端UE可以使用基站分配的发送资源来与基站或中继UE进行通信。
在步骤S303中,接收所述基站返回的重配消息,所述重配消息中携带有所述基站返回的发送资源或发送资源池。
示例地,基站在接收到资源请求后,基站可以生成携带有发送资源或发送资源池的重配消息,来为远端UE返回发送资源或发送资源池。
其中,重配消息可以是RRC重配消息,是基站依据远端UE上报的资源请求生成的,用于为远端UE分配发送资源或发送资源池。
应当理解,该方法还可以包括:接收系统消息,所述系统消息可以由基站广播。当远端UE被基站网络覆盖时,所述远端UE直接接收基站广播的系统消息;当远端UE未被基站网络覆盖时,也可以由基站发送给中继UE并由所述中继UE转发给所述远端UE,本公开对此不作限制。
通过上述技术方案,远端UE可以接收中继UE从基站获取的系统信息;在确定系统信息中不存在发送资源池的情况下,使用预配置的发送资源进行侧行链路发送,以保障远端UE与中继UE之间的通信连接,避免远端UE的通信和业务中断。
图4是根据一示例性实施例示出的一种资源选择方法的流程图,如图4所示,该资源选择方法应用于用户设备中,该方法包括以下步骤。
在步骤S401中,响应于接收到的系统信息中不存在发送资源池,使用预配置的发送资源进行侧行链路发送。
示例的,本公开的实施例中的步骤S401可以参照上述步骤S201,不再赘述。
在步骤S402中,在接收到所述基站返回的发送资源或发送资源池的情况下,停止使用所述预配置的发送资源。
示例地,在远端UE接收到基站返回的发送资源或发送资源池的情况下,表明远端UE可以利用向基站请求的发送资源,来继续与基站或中继UE进行数据或信令的传输,此时可以不再使用预配置的发送资源与基站或中继UE进行数据或信令的传输。
其中,基站在接收到远端UE发送的资源请求后,可以将发送资源或发送资源池打包为重配信息返回至远端UE。
通过上述技术方案,在远端UE接收到基站返回的重配消息中携带的发送资源或发送资源池的情况下,表明远端UE向基站请求发送资源成功,此时远端UE可以使用基站分配的发送资源来进行侧行链路发送,而无需继续使用预配置的发送资源。
图5是根据一示例性实施例示出的一种资源选择方法的流程图,如图5所示,该资源选择方法应用于用户设备中,该方法包括以下步骤。
在步骤S501中,在所述用户设备满足以下任一条件的情况下,确定所述用户设备通过所述中继设备与所述基站连接:
所述用户设备未被网络覆盖;
所述用户设备与所述基站之间的参考信号接收功率小于阈值;
所述用户设备选择所述中继设备;
所述用户设备配置有直接链路和间接链路,将所述间接链路作为主链路,所述间接链路为所述用户设备通过所述中继设备与所述基站通信的链路。
其中,远端UE未被基站网络覆盖时,表明远端UE需要通过中继UE来与基站连接,进而与基站进行交互,所以当远端UE未被基站网络覆盖时,远端UE是通过中继UE来与基站建立连接的。
其中,远端UE与基站之间的RSRP(Reference Signal Receiving Power,参考信号接收功率)小于阈值时,说明远端UE接收到的网络信号较差,无法接入基站的网络,此时远端UE也是通过中继UE来与基站建立连接。
其中,远端UE可以直接与基站连接,远端UE也可以通过中继UE来与基站连接,当远端UE从多个中继UE中选择一个中继UE来与基站通信时,说明远端UE是通过中继UE来与基站连接。
示例地,在远端UE未被网络覆盖,或远端UE与基站之间的RSRP小于阈值时,确定远端UE可能会选择中继UE。
其中,远端UE与基站之间也存在一条SRB(Signaling Radio Bearer,无线信令承载)主链路与多条SRB非主链路,当间接链路作为SRB主链路时,表明远端UE、中继UE与基站之间的间接链路是发送数据或信令的主要链路,此时可以确定远端UE通过中继UE与基站连接,来传输数据或信令。
远端UE配置有至少一条直接链路与间接链路,来与基站通信,直接链路是远端UE直接与基站连接的链路,间接链路是远端UE通过中继UE与基站通信的链路。间接链路可以通过以下任一条件确定为主链路,直接链路也可以通过以下任一条件确定为主链路。
示例地,在间接链路通过以下任一条件确定为主链路包括:
所述间接链路用于传输无线信令承载,无线信令承载可以为SRB;
所述间接链路是传输所述无线信令承载的主传输路径;
所述间接链路连接失败的情况下,触发了所述基站的重配信息;
所述间接链路是用于保持所述用户设备与所述基站连接的路径;
所述间接链路为锚点路径;
所述间接链路连接的是所述用户设备的主小区。
其中,间接链路用于传输SRB包括间接链路是用于传输SRB的主传输路径与间接链路是用于传输SRB的非主传输路径;当间接链路是用于传输SRB时,可以确定间接链路可以用于接入网络,此时可以确定间接链路是主链路。
其中,间接链路是用于传输SRB的主传输路径时,也可以确定间接链路用于接入网络,确定间接链路是主链路。
其中,重配消息是远端UE未被网络覆盖的情况下,基站通过中继UE返回给远端UE的。远端UE在接收重配消息后,会依据重配消息中的发送资源或发送资源池来与基站建立连接,该间接链路可以实现主要的信令或数据转发,所以可以作为主链路。
其中,在间接链路是用来保持远端UE与基站连接的路径时,说明该间接链路可以实现远端UE与基站之间信令或数据转发,而其余链路可能无法保持远端UE与基站的连接,进而无法实现信令或数据转发,所以可以将该间接链路作为主链路。
其中,在间接链路为锚点路径时,由于锚点路径是主路径的另外一种名称,所以间接路径为主路径。
其中,在双连接(dual-connectivity,DC)中,与核心网有控制信令交互的接入网设备可以称为主节点(master node,MN),其他接入网设备可以称为辅节点(secondary node,SN)。主节点为UE提供的服务小区组可以称为主小区组(master cell group,MCG),从节点为终端设备提供的服务小区组可以称为辅小区组(secondary cell group,SCG),主小区起到核心控制作用,辅小区用于辅助主小区实现数据传输。在间接链路连接的是远端UE的主小区时,说明间接链路是主要控制链路,所以间接链路可以作为主链路。
通过上述技术方案,可以确定UE是通过中继UE接入基站网络的远端UE,并在确定远端UE之后,远端UE确认接收到的系统信息是否存在发送资源池,如果不存在发送资源池,采用预配置的发送资源进行侧行链路发送,避免远端UE的通信和业务中断。
图6是根据一示例性实施例示出的一种资源选择方法的流程图,如图6所示,该资源选择方法应用于用户设备中,该方法包括以下步骤。
在步骤S601中,响应于所述系统信息中不存在一般发送资源池,也不存在特殊发送资源池,使用所述预配置的发送资源进行侧行链路发送。
示例地,基站可以根据网络中是否具有资源池以及具有哪些资源池生成系统信息,系统信息中可以同时存在一般发送资源池与特殊发送资源池,也可以存在其中一者,也可以不存在发送资源池,远端UE确定接收到的系统信息中不存在一般发送资源池,也不存在特殊发送资源池的情况下,确定系统信息中不存在发送资源池,为了保障远端UE能够进行侧行链路发送,可以使用远端UE预配置的发送资源进行侧行链路发送。
在步骤S602中,在所述系统信息中存在一般发送资源池的情况下,根据所述一般发送资源池进行侧行链路发送。
示例地,在系统信息中存在一般发送资源池与特殊发送资源,或存在一般发送资源池的情况下,优先采用一般发送资源池,与中继UE或基站进行数据或信令的交互。
远端UE可以从一般发送资源池中选择至少一种发送资源,来进行侧行链路发送。
在步骤S603中,在所述系统信息中不存在所述一般发送资源池,且存在特殊发送资源池的情况下,根据所述特殊发送资源池进行侧行链路发送。
示例地,在系统信息中不存在一般发送资源池,且存在特殊发送资源池的情况下,采用特殊发送资源池,与中继UE或基站进行数据或信令的交互。
远端UE可以从特殊发送资源池中选择至少一种发送资源,来进行侧行链路发送。
通过上述技术方案,可以在接收到的系统信息中不存在发送资源池,远端UE可能会断开通信的情况下,采用预配置的发送资源来进行侧行链路发送,以保障远端UE的正常通信。
图7是根据一示例性实施例示出的一种资源选择方法的流程图,如图7所示,该资源选择方法应用于基站中,该方法包括以下步骤。
在步骤S701中,进行侧行链路接收以获得用户设备的资源请求,其中,所述资源请求是在系统信息中不存在发送资源池的情况下,所述用户设备使用预配置的发送资源发送的。
示例地,基站可以是用于进行公共移动通信的基站,例如可以是上述服务小区的基站,在5G中该基站可以是gNodeB。
进行侧行链路接收可以为进行sidelink接收,基站进行侧行链路接收的过程中,可以携带基站与中继UE或远端UE交互的数据或指令,在侧行链路中进行传输。例如在进行侧行链路接收的过程中,可以携带远端UE发送给基站的资源请求,也可以携带基站发送给远端UE的RRC重配消息等。
值得说明的是,发送资源池可以为中继侧行链路发送资源池,发送资源可以为中继侧行链路发送资源,中继侧行链路包括远端UE、中继UE与基站,远端UE与基站之间通过中继UE进行交互。中继侧行链路发送资源为sidelink发送资源,中继侧行链路发送资源池为sidelink发送资源池,这两种发送资源用于UE与UE之间进行通信。
其中,所述资源请求是所述用户设备在从所述中继设备接收到的系统信息不存在所述发送资源池的情况下,使用所述预配置的发送资源发送的。
示例地,所述资源请求是所述用户设备在所述中继设备的基站的系统信息中不存在所述发送资源池的情况下,使用所述预配置的发送资源向所述基站发送的。
基站可以向远端UE发送系统资源,基站通过广播的方式将系统资源广播在服务小区中,位于服务小区内的中继UE将系统资源发送给远端UE,实现远端UE从中继设备的基站进行的系统信息的接收。
通过上述方案,在系统信息不存在发送资源池的情况下,进行侧行链路接收,得到用户设备使用预配置的发送资源发送的资源请求,使得远端UE能够与中继UE或基站进行数据或信令的交互,避免远端UE的通信与业务中断。
图8是根据一示例性实施例示出的一种资源选择方法的流程图,如图8所示,该资源选择方法应用于基站中,该方法包括以下步骤。
在步骤S801中,进行侧行链路接收,得到所述用户设备进入连接态后,使用预配置的发送资源发送的资源请求。
示例地,在远端UE接收到系统信息,并确定系统信息中不存在发送资源池的情况下,远端UE进入连接态。
其中,远端UE进入连接态表明远端UE需要与中继UE或基站进行数据或信令的交互,且远端UE处于未被网络覆盖的状态。
当基站接收到资源请求之后,可以确定远端UE处于脱网状态,远端UE的通信或业务可能会存在中断的情况。
在步骤S802中,向所述用户设备返回重配消息,所述重配消息中携带有所述基站返回的发送资源或发送资源池。
其中,基站在接收到资源请求后,可以生成重配消息,来为远端UE分配发送资源。重配消息可以是RRC重配消息,是基站响应于远端UE上报的资源请求所生成的。
示例地,通信有两种发送资源分配方式,一种是基站进行网络动态调度的方式,另一种是UE在重配消息的资源池或预配置的资源池或系统信息的资源池中自主选择的方式。
在动态调度方式下,UE向基站发送资源请求,基站确定选择动态调度方式,在选择动态调度方式后,基站将动态调度指示反馈给UE,动态调度指示中携带有UE需要上报的信息;UE依据动态调度指示,将自身的缓存数据发送给基站;基站依据缓存数据动态调度发送资源,并将发送资源返回给UE,UE依据发送资源实现通信。其中,可以为被基站网络覆盖的中继UE。
在自主选择方式下,若远端UE侧存在系统信息的发送资源池,远端UE则选择系统信息的资源池中的发送资源,来与中继UE或基站进行交互;若远端UE接收到的系统信息中未携带有发送资源池,远端UE则可以选择预配置的发送资源池中的发送资源,来与中继UE进行交互,将资源请求通过中继UE发送给基站;基站再根据远端UE上报的资源请求生成重配消息,将重配消息通过中继UE下发至远端UE,重配消息中可以携带有基站发送给远端UE的发送资源或发送资源池。
值得说明的是,发送资源或发送资源池可以为传输数据的资源,使用发送资源或发送资源池可以实现远端UE与其余设备之间的数据交互。
通过上述技术方案,在系统信息不存在发送资源池的情况下,进行侧行链路接收,得到用户设备使用预配置的发送资源发送的资源请求,使得远端UE能够与中继UE或基站进行数据或信令的交互,避免远端UE的通信与业务中断。

示例的,本公开的实施例中停止使用预配置的发送资源可以参照上述步骤S402,不再赘述。
通过上述技术方案,在基站向远端UE返回重配消息后,表明远端UE向基站请求发送资源成功,此时远端UE可以使用基站分配的发送资源来与中继UE或基站传输信令或数据,而无需继续使用预配置的发送资源。
