这里,所述第一通信系统为长期演进LTE系统,所述第二通信系统为新无线NR通信系统;或者,第一通信系统为NR通信系统,第二通信系统为LTE系统。
其中,所述终端设备装载有第一通信系统的V2X模块以及第二通信系统的V2X模块的设备,且所述终端设备接入第一通信系统;具体来说,终端设备既装载有LTE V2X和NR V2X模块。所述V2X即vehicle to everything,即车对外界的信息交换。
本实施例提供的方案,应用于当终端设备处于NR系统中时,需要与仅有LTE V2X模块的终端设备进行通信的时候;或者,当终端设备处于LTE系统中时,需要与仅具备NR V2X模块的终端设备进行通信的时候,就需要从网络侧获取对端也就是第二通信系统的V2X通信资源。
所述接收终端设备发来的资源请求信息,包括:接收所述终端设备发来的针对第二通信系统的V2X资源的缓存状态报告BSR。
其中,所述针对第二通信系统的V2X资源的缓存状态报告BSR,包括:

或者,
第一通信系统的至少一个用于第二通信系统的V2X资源申请的边链路BSR MAC CE;比如,当第一通信系统为NR、第二通信系统为LTE时,如下表所示,在NR MAC CE中新增一个或多个专门用于LTE V2X资源申请的MAC CE,在列表中增加用于获取LTE边链路BSR的MAC CE的相关信息,其编号“xxxxx”可以根据实际情况进行设置,本实施例中不进行赘述:

可见,通过采用上述方案,就能够在终端设备请求其他通信系统的V2X资源的时候,为其调度其他通信系统的V2X资源,从而使得终端设备能够获得其他通信系统的传输资源,实现了在多个通信系统共存的场景下为终端设备进行不同通信系统的资源调度的方案。

其中,所述终端设备装载有第一通信系统的V2X模块以及第二通信系统的V2X模块的设备,且所述终端设备接入第一通信系统;具体来说,终 端设备既装载有LTE V2X和NR V2X模块。所述V2X即vehicle to everything,即车对外界的信息交换。
本实施例提供的方案,应用于当终端设备处于NR系统中时,需要与仅有LTE V2X模块的终端设备进行通信的时候;或者,当终端设备处于LTE系统中时,需要与仅具备NR V2X模块的终端设备进行通信的时候,就需要从网络侧获取对端也就是第二通信系统的V2X通信资源。比如,装载有LTE V2X和NR V2X模块的UE如果需要与仅有LTE V2X模块的UE进行Sidelink通信,需要接收NR基站广播或者通过RRC重配消息发送的LTE V2X的相关配置消息。
所述广播或通过RRC重配置消息发送第二通信系统的V2X资源,包括以下之一:
通过新的系统信息块SIB广播第二通信系统的V2X资源;
通过新增加的针对第二通信系统的V2X的信元广播第二通信系统的V2X资源。
即在NR系统消息中新定义一种SIB专门用于广播LTEV2X相关配置,比如:可以在SIB中增加新的SIB类型,SIB xx其中的“xx”可以根据实际情况设置,只是不与现有技术中已经公开的SIB的编号相同即可;在SIB xx中包括有LTE V2X边链路通信配置,在新增加的SIB xx中广播V2X资源,这里需要理解的是,只要看到信道SIB xx就确定是LTE V2X的资源,比如以下示例中SIB21即为新的SIB,通过以下描述可以发送V2X的资源配置信息:
或者,通过新增加的针对第二通信系统的V2X的信元广播第二通信系 统的V2X资源,比如可以在SIB中增加一个描述第二通信系统即LTE系统的V2X资源的语句:S1-LTE-V2X-ConfigCommon。
或者,所述RRC重配置消息中,包括:
针对第二通信系统的V2X配置信息的信元,即RRCConnectionReconfiguration增加sl-LTE-V2X-ConfigDedicated IE。或者,在针对V2X配置信息的信元中添加针对第二通信系统的V2X配置信息的信元;即RRCConnectionReconfiguration的sl-V2X-ConfigDedicated IE中增加LTE V2X配置相关IE。
可见,通过采用上述方案,就能够由第一通信系统为终端设备调度第二通信系统的V2X资源,从而使得终端设备能够获得其他通信系统的传输资源,实现了在多个通信系统共存的场景下为终端设备进行不同通信系统的资源调度的方案。
实施例五、
本申请实施例提供了一种第一基站,所述第一基站位于第一通信系统,如图5所示,包括:
第一通信接口51,用于接收终端设备发来的资源请求信息;其中,所述资源请求信息用于请求调度第二通信系统的V2X资源;
第一处理器52,用于通过第一通信接口为所述终端设备调度用于第二通信系统的V2X资源。
这里,所述第一通信系统为长期演进LTE系统,所述第二通信系统为新无线NR通信系统;或者,第一通信系统为NR通信系统,第二通信系统为LTE系统。
其中,所述终端设备装载有第一通信系统的V2X模块以及第二通信系统的V2X模块的设备,且所述终端设备接入第一通信系统;具体来说,终端设备既装载有LTE V2X和NR V2X模块。所述V2X即vehicle to everything,即车对外界的信息交换。
本实施例提供的方案,应用于当终端设备处于NR系统中时,需要与仅有LTE V2X模块的终端设备进行通信的时候;或者,当终端设备处于LTE系统中时,需要与仅具备NR V2X模块的终端设备进行通信的时候,就需要从网络侧获取对端也就是第二通信系统的V2X通信资源。
所述第一通信接口51,接收所述终端设备发来的针对第二通信系统的V2X资源的缓存状态报告BSR。
其中,所述针对第二通信系统的V2X资源的缓存状态报告BSR,包括:
第一通信系统的边链路BSR的MAC控制元素CE格式中的针对第二通信系统的V2X资源申请域;比如,当第一通信系统为NR、第二通信系统为LTE时,如图2所示,在NR Sidelink BSR MAC Control Elements format中增加LTE PC5资源申请域(以总计偶数个LCG为例),图中可见,可以在MAC CE格式中增加针对LTE逻辑信道组的相关信息域,基于该信息进行PC5资源申请;
或者,
第一通信系统的至少一个用于第二通信系统的V2X资源申请的边链路BSR MAC CE;比如,当第一通信系统为NR、第二通信系统为LTE时,如下表所示,在NR MAC CE中新增一个或多个专门用于LTE V2X资源申请的MAC CE,在列表中增加用于获取LTE边链路BSR的MAC CE的相关信息,其编号“xxxxx”可以根据实际情况进行设置,本实施例中不进行赘述:
| 编号Index | 逻辑信道标识(LCID)values |
| 00000 | CCCH |
| …… | …… |
| xxxxx | 缩减的LTE边链路(Sidelink)BSR |
| xxxxx | LTE Sidelink BSR |
| …… | …… |
或者,
通过第一通信系统的边链路BSR的MAC CE格式中的指示位,其中,所述指示位用于指示请求针对第一通信系统或第二通信系统的V2X资源;所述指示位可以根据实际情况进行设置,可以设置1bit作为指示位,可以设置当指示位=1时,表征针对第二通信系统的V2X资源,当指示为=0时,标识针对第一通信系统的V2X资源,反之亦可,本实施例不做穷举。比如,当第一通信系统为NR、第二通信系统为LTE时,NR Sidelink BSR MAC Control Elements format中增加1bit指示当前format属于LTE PC5资源申请还是NR PC5资源申请。
还需要说明的是,为所述终端设备调度用于第二通信系统的V2X资源之前,所述第一处理器52,获取第二通信系统的V2X资源配置信息。
其获取第二通信系统的V2X资源配置信息的方式,可以第一处理器52,通过第一通信接口51从第二通信系统的第二基站中获取。比如,LTE中V2X无论是模式3还是模式4,均需要基站给UE发送用于V2X sidelink通信的配置,因此在LTE V2X和NR V2X共存场景下,任何一个基站为了支持调度其他RAT V2X,均需要知道其他V2X的相关配置,比如NR基站需要调度LTE V2X,需要知道LTE V2X相关配置。
其中,模式3:车载终端的传输资源是由基站分配的,车载终端根据基站分配的资源在侧行链路上进行数据的发送;基站可以为终端分配单次传输的资源,也可以为终端分配半静态传输的资源。模式4:车载终端采用侦听(sensing)+预留(reservation)的传输方式。车载终端在资源池中通过侦听的方式获取可用的传输资源集合,终端从该集合中随机选取一个资源进行数据的传输。
具体的获取第二通信系统的V2X资源配置信息的方式为:
第一处理器52通过操作管理维护OAM信息接收第二通信系统的V2X 资源配置信息;
或者,第一处理器52与所述第二通信系统的第二基站通过Xn接口交互各自通信系统的V2X资源配置信息;
或者,第一处理器52当所述第一基站与第二基站为同一个基站时,直接获取第二通信系统的V2X资源配置信息。
即可以由第二通信系统的第二基站直接通过OAM信息发给其相邻的第一基站;或者,当第一基站与第二基站不为同一个基站的时候,通过Xn接口进行交互,获取相关的V2X资源配置信息;以及当第一基站与第二基站在物理上为相同基站时,可以直接从内部获取V2X资源配置信息。
其中,所述V2X资源配置信息包括以下至少之一:

V2X发送资源池;
V2X调度的资源池;
V2X同步配置;
V2X间频率信息列表;
V2X资源选择配置;
V2X逻辑信道组信息列表。
本实施例提供的方案,参见图3进行说明,以第一通信系统为NR,第二通信系统为LTE为例再进行说明,即终端设备1为装置LTE V2X模块以及NR V2X模块的设备,终端设备2为仅装载LTE V2X模块的设备;如果终端设备1需要与仅有LTE V2X模块的终端设备2进行模式3的Sidelink通信,则接入NR基站的终端设备1,需要根据NR基站关于logicalChGroupInfoList的配置向NR基站发起用于LTE V2X的BSR(Buffer Status Report,缓存状态报告)请求;NR基站根据与相邻基站交互的LTE V2X资源配置等参数,为终端设备1调度用于LTE sidelink的资源。
可见,通过采用上述方案,就能够在终端设备请求其他通信系统的V2X 资源的时候,为其调度其他通信系统的V2X资源,从而使得终端设备能够获得其他通信系统的传输资源,实现了在多个通信系统共存的场景下为终端设备进行不同通信系统的资源调度的方案。
