技术领域
本公开涉及通信技术领域,尤其涉及一种直接链路通信的方法、终端及网络设备。
背景技术
在3GPP长期演进技术(Long Term Evolution,LTE)智能网联汽车技术(Vehicle-to-Everything,V2X)的通信系统中,基站与终端之间通过Uu接口(用户终端与网络的空中接口)进行上/下行链路通信,终端与终端之间通过PC5接口即近距离通信端口5(Proximity Communication Port 5)进行直接链路(Sidelink)通信。相关技术中的LTE V2X技术支持如下2种工作模式:
终端竞争模式:此模式下,系统中用户设备或者终端(User equipment,UE)的发送资源分配和调制与编码策略(Modulation and Coding Scheme,MCS)格式完全由终端自行(分布式)决定,通过“感知+半持续占用”的方法实现分布式调度功能,无需基站的介入。在LTE V2V标准中称为Mode 2,在LTE V2X以及后续标准中称为Mode 4(分布式资源调度模式)。
基站调度模式:此模式下,UE的PC5接口发送资源和MCS都由LTE基站进行,其中LTE基站的Uu接口向终端发送调度信令,终端也可以通过Uu接口向基站上报测量信息。在LTE V2V标准中称为Mode 1,在LTE V2X以及后续标准中称为Mode 3(集中式资源调度模式)。
在基站调度模式下,系统中的资源分配由基站主导或辅助。覆盖内Uu接口通信,主要是通过Uu接口转发V2X的信息,过程遵循了相关技术中LTE的大多数机制,上行采用单播(Unicast)的方式,V2X终端将信息发送给基 站(eNB);下行是基站eNB通过广播(broadcast)或者多播(Multicast)的方式将信息发送给其他V2X终端。根据V2X终端(UE)与LTE基站网络的耦合程度不同,主要分为如下工作方式:
UE工作于Mode 3模式,LTE基站通过Uu接口(2.6GHz)向UE发送参数配置和调度信令,跨载波配置、调度在专用频段(5.9GHz)通过PC5接口通信的UE,属于覆盖内动态调度。
UE工作于Mode 4模式,LTE基站将配置资源的参数,通过Uu接口(2.6GHz)发送给UE,UE收到之后,在专用频段(5.9GHz)使用这些配置好的资源,通过PC5接口与其他UE通信,属于覆盖内半静态配置。
UE工作于Mode 4模式,没有任何蜂窝网络辅助,所有UE采用预配置参数,且预配置参数指明工作于专用频段(5.9GHz),属于覆盖外场景。
根据LTE V2X频谱的分配情况,LTE V2X可以分别支持PC5接口在专用载波(5.9GHz)通信,和Uu接口与蜂窝共享载波(2.6GHz)通信。在E-UTRAN(LTE)网络覆盖范围内,V2X的节点根据接收到信令中的配置信息,来判断这个节点是通过Mode 3还是Mode 4的方式进行通信,这样的信令包括系统信息块21(SystemInformationBlock21,SIB21)和无线资源控制(Radio Resource Control,RRC)重配置消息。
然而,在NR发展的初期,基于NR技术的终端设备会包含双模块设计,即同时包含LTE通信模块和NR通信模块,保证终端设备既能够通过LTE Uu和sidelink接口通信,又能够通过NR Uu和sidelink通信。
LTE蜂窝网络覆盖,NR终端是双模块,即同时包含LTE通信模块和NR通信模块:LTE基站(eNB)通过Uu接口与终端的NR模块通信,进行资源分配和控制终端的NR sidelink通信。相关技术中的eNB只能按照相关技术中的协议发送SIB21消息和RRC重配置消息给空闲(IDLE)态的V2X终端来确定通信模式是集中式的资源调度模式(Mode 3)还是分布式的资源调度模式(Mode 4),而NR V2X终端采用的更新的技术、设计和结构标准,因此,NR V2X终端能否正常接收并解读出eNB发送的SIB21和RRC重配置消息,就是相关技术中所面临的问题。
发明内容
本公开实施例提供了一种直接链路通信的方法、终端及网络设备,保证了NR V2X终端可以正常与其它终端进行直接链路通信。
为解决上述技术问题,本公开的实施例提供如下技术方案:

至少支持新无线系统NR通信的第一终端,接收第一网络设备发送的资源配置信息;
如果所述第一网络设备发送的资源配置信息中包括第一预设信息,则进入分布式资源调度模式与第二终端进行直接链路通信,否则,与第二网络设备建立连接,并接收所述第二网络设备发送的资源配置信息;

具体实施方式
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例,然而应当理解,可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反,提供这些实施例是为了能够更透彻地理解本公开,并且能够将本公开的范围完整的传达给本领域的技术人员。
本公开提供一种基于LTE Uu口通信的网络设备(如基站)和基于NR Uu口通信的网络设备(如基站)分别或者协同配置、调度NR V2X终端进行直接链路传输的方法。NR V2X终端(UE)可以是双模(包括LTE模块和NR模块),也可以是单模,只包含NR模块。
本公开的实施例中,NR V2X终端可以是由LTE基站配置、调度,也可以同NR基站配置、调度;也可以由LTE基站和NR基站协同配置、调度。
此时,UE可以选择通过Uu接口只监听来自NR基站的控制信令,也可以选择同时监听LTE基站和NR基站的控制信令。
在确认是上述某一种情况以后,基站通过Uu接口与NR终端通信,发送SIB消息和RRC重配置消息或者其他系统消息,确定UE的工作模式。这里的SIBn可以是LTE技术中的SIB21,也可以是新的SIB消息。RRC重配置消息可以是LTE技术中的RRC消息,也可以是新的任何其他重配置消息。

下面结合具体实施例,说明上述方法的具体实现过程:
实例1:如图2所示,第一终端(如空闲(IDLE)态UE1)如果收到SIB21(SystemInformationBlock21)(来自第一网络设备的资源配置信息,该第一网络设备可以是LTE基站),UE1检查SIB21中的X(如SL-V2X-ConfigCommon-r14)是否包含发送资源池的信息Y(如V2X-CommTxPoolNormalCommon-r14)。如果IDLE态UE1收到的SIB21中包含了发送资源池的信息Y,则IDLE态UE1进入分布式资源调度模式(Mode4),直接利用该资源池的信息Y进行资源选择过程,并利用选择的资源与第二终端进行直接链路通信。
IDLE态UE1如果收到SIB21,UE检查发现SIB21中的X不包含发送资源池的信息Y,则IDLE态UE1发起RRC连接过程进入连接态(这里可以与第二网络设备建立连接,第二网络设备可以与第一网络设备相同或者不同)。UE1接收第二网络设备发送的资源配置信息(如RRC重配置消息)中的Z(如SL-V2X-ConfigDedicated-r14)包含了Z1(如ue-Selected-r14)的信息,则UE1进入分布式资源调度模式(Mode4),利用配置的资源池信息进行资源选择过程。
IDLE态UE1如果收到SIB21,UE检查发现SIB21中的X不包含发送资源池的信息Y。则IDLE态UE1发起RRC连接过程进入连接态(这里可以与第二网络设备建立连接,第二网络设备可以与第一网络设备相同或者不同)。UE1接收第二网络设备发送的资源配置信息(如RRC重配置消息)中的Z(如SL-V2X-ConfigDedicated-r14)包含了Z2(如scheduled-r14)的信息,则UE1进入Mode3(集中式资源调度模式),根据基站的调度,进行PC5接口通信。
具体的,如图3所示,UE1(发射(transmitter))进入集中式资源调度模式(Mode3),根据基站的调度,进行PC5接口通信包括:
UE1通过Uu接口向LTE基站(第二网络设备)上报自己的资源调度请求以及辅助信息,包括业务相关信息(包大小、业务周期等)、位置信息等;
LTE基站配置NR sidelink Mode 3资源占用情况;
LTE基站向UE1发送DCI format N调度信令;
该UE1根据DCI format N中指示的信息,与第二终端UE2(接收(receiver))进行NR sidelink通信。
实例2:
如图2所示,第一终端(如IDLE态UE1)如果收到SIB21(SystemInformationBlock21)(来自第一网络设备的资源配置信息,该第一网络设备可以是LTE基站),UE1检查SIB21中的X(如SL-V2X-ConfigCommon-r14)是否包含发送资源池的信息Y(如V2X-CommTxPoolNormalCommon-r14)。如果IDLE态UE1收到的SIB21中包含了发送资源池的信息Y,则IDLE态UE1进入分布式资源调度模式(Mode4),利用该资源池的信息Y进行进一步资源划分、重新分配等操作,再进入资源选择过程,并利用选择的资源与第二终端进行直接链路通信。
IDLE态UE1如果收到SIB21,UE1检查发现SIB21中的X不包含发送资源池的信息Y。则IDLE态UE1发起RRC连接过程进入连接态(这里,可以与第二网络设备建立连接,第二网络设备可以与第一网络设备相同或者不同)。UE1接收第二网络设备发送的资源配置信息(如,RRC重配置消息)中的Z(如SL-V2X-ConfigDedicated-r14)包含了Z1(如ue-Selected-r14)的信息,则UE1进入分布式资源调度模式(Mode4),利用该RRC重配置消息 配置的资源,进行进一步资源划分、重新分配等操作。
IDLE态UE1如果收到SIB21,UE1检查发现SIB21中的X不包含发送资源池的信息Y。则IDLE态UE1发起RRC连接过程进入连接态(这里可以与第二网络设备建立连接,第二网络设备可以与第一网络设备相同或者不同)。UE1接收第二网络设备发送的资源配置信息(如RRC重配置消息)中的Z(如SL-V2X-ConfigDedicated-r14)包含了Z2(如scheduled-r14)的信息,则UE1进入Mode3(集中式资源调度模式),根据基站的调度,进行PC5接口通信。
具体的,如图4所示,UE1(发射(transmitter))进入Mode3(集中式资源调度模式),根据基站的调度,进行PC5接口通信包括:
UE1通过Uu接口向LTE基站(第二网络设备)上报自己的资源调度请求以及辅助信息,包括业务相关信息(包大小、业务周期等),位置信息等;
LTE基站配置NR sidelink Mode 3资源占用情况;
LTE基站向UE1发送DCI format N调度信令;
该UE1根据DCI format N中指示的信息,会将SIB21或者RRC重配置下来的资源,进一步组合、划分,以便于将资源池高效利用;
该UE1与UE2(接收(receiver))进行NR sidelink通信。
该实施例中,SIB21包含的资源配置信息由LTE基站配置的,而NR网络会采用多种子载波间隔(15kHz,30kHz,60kHz,120kHz)、BWP、更短的发送时隙slot等新特性,因此,NR UE1会将SIB21和RRC重配置下来的资源进一步组合、划分,以便于将资源池高效利用。
UE1对LTE基站配置下来的资源,按照NR中的更小粒度进行划分、重分配(re-configuration),然后再利用这些细分资源通过PC5接口与其他UE进行sidelink通信。
实例3:
该实例3与实例1相同,不同在于SystemInformationBlock21(SIB21)可以被其他系统消息或SIBn替代,例如,但不限于SIB23。
实例4:
该实例4中确定UE的工作模式与实例1相同,如图2所示。但终端进入Model 3与UE2进行NR sidelink通信时,如图5所示,NR基站与LTE基 站建立通信,LTE基站与NR基站连接使用X2或Xn接口。NR基站将NR sidelink的配置、调度等信息(即资源配置信息)发送给LTE基站,LTE基站将这些配置、调度等信息放在SIB21中,配置给UE1。
实例5:
该实例4中确定UE的工作模式与实例2相同,如图2所示。但终端进入Model 3与UE2进行NR sidelink通信时,NR基站与LTE基站建立通信,LTE基站与NR基站连接使用X2或Xn接口。NR基站将NR sidelink的配置、调度等信息(即资源配置信息)发送给LTE基站,LTE基站将这些配置、调度等信息放在SIBn中,配置给UE1。
实例6:
如图2所示,第一终端(如IDLE态UE1)如果收到SIBn(SystemInformationBlockn)(来自第一网络设备的资源配置信息,该第一网络设备可以是NR基站),UE1检查SIBn中的X(如SL-V2X-ConfigCommon-r14)是否包含发送资源池的信息Y(如V2X-CommTxPoolNormalCommon-r14)。如果IDLE态UE1收到的SIBn中包含了发送资源池的信息Y(如V2X-CommTxPoolNormalCommon-r14),则IDLE态UE1进入分布式资源调度模式(Mode 4),直接利用该资源池的信息Y进行资源选择过程。
IDLE态UE1如果收到SIBn,UE1检查发现SIBn中的X不包含发送资源池的信息Y。则IDLE态UE1发起RRC连接过程进入连接态(这里,可以与第二网络设备建立连接,第二网络设备可以与第一网络设备相同或者不同)。UE1接收第二网络设备发送的资源配置信息(如,RRC重配置消息)中的Z(如SL-V2X-ConfigDedicated-r14)包含了Z1(如ue-Selected-r14)的信息,则UE进入分布式资源调度模式(Mode4),利用RRC重配置消息配置的资源,进行资源选择过程。
IDLE态UE1如果收到SIBn,UE检查发现SIBn中的X不包含发送资源池的信息Y。则IDLE态UE1发起RRC连接过程进入连接态(这里可以与第二网络设备建立连接,第二网络设备可以与第一网络设备相同或者不同)。UE1接收第二网络设备发送的资源配置信息(如RRC重配置消息)中的Z(如 SL-V2X-ConfigDedicated-r14)包含了Z2(如scheduled-r14)的信息,则UE1进入集中式资源调度模式(Mode3),根据基站的调度,进行PC5接口通信。
具体的,如图6所示,UE1进入集中式资源调度模式(Mode3),根据基站的调度,进行PC5接口通信包括:
UE1(发射(transmitter))通过Uu接口向NR基站上报自己的资源调度请求以及辅助信息,包括业务相关信息(包大小、业务周期等),位置信息等;
NR基站配置NR sidelink Mode 3资源占用情况;
NR基站向UE1发送DCI format N调度信令;
该UE1根据DCI format N中指示的信息,与UE2(接收(receiver))进行NR sidelink通信。
实例7:
当NR网络和LTE网络覆盖同时存在,双模的NR基站,可以通过NR Uu配置、调度LTE sidelink和NR sidelink,该实施例中,NR基站可以包括:LTE模块和NR模块,NR模块依据上述如实例6中的方法,与终端1进行交互,控制UE1与UE2进行NR sidelink通信;LTE模块可以依据如实施例1至5任一种的方法,与终端1进行交互,控制UE1与UE2进行NR sidelink通信。
实例8:
该实例8中确定UE的工作模式与实例6相同,如图2所示。但终端进入Model 3与UE2进行NR sidelink通信时,如图7所示,NR基站与LTE基站建立通信,LTE基站与NR基站连接使用X2或Xn接口。LTE基站将LTE sidelink的配置、调度等信息发送给NR基站,NR基站将这些配置、调度等信息放在系统消息、SIB21和RRC重配置消息中。
NR基站通过Uu接口配置、调度NR sidelink和LTE sidelink,此时,双模UE只需监听NR Uu接口的消息即可。
本公开的上述实施例中,SIBn可以被其他任何名称替代,例如但不限于SIB23;Mode 3和Mode 4可以被其他任何名称替代,例如但不限于Mode 5和Mode 6;X,Y,Z,Z1和Z2可以被其他任何名称替代。Xn接口可以被其他任何名称替代,例如但不限于X3。支持LTE的第一基站泛指4G所有基站,包括LTE基站、LTE-A演进基站等。UE1、UE2是NR V2X终端、道路 旁设备等进行sidelink通信的设备。NR基站和LTE基站通过Uu接口发送SIBn给NR终端,控制NR sidelink通信,包括通信模式确定、资源池配置等。SIBn中所包含的资源(池)配置信息与SIB21不同。LTE基站通过Uu接口发送的SIB21配置消息给NR终端后,NR终端可以将得到的资源(池)进一步分配、划分,从而更加高效利用资源。NR网络和LTE网络将独立工作,二者可能接入同一个核心网,也可能接入不同的核心网。NR网络(基站)通与LTE网络(基站)通过X2接口或Xn接口建立连接进行通信,交换NR sidelink资源配置、调度等信息。
本公开的上述实施例应用于LTE和NR V2X的通信中。NR基站和LTE基站通过Uu接口控制、调度NR sidelink的方法,增大了NR V2X终端的通信范围,提高了资源(池)的利用效率,提高的系统的性能和稳定性。
