针对V2X通信技术,第3代合作伙伴计划(3rd Generation Partnership Project,3GPP)的长期演进(Long Term Evolution,LTE)系统中,已经完成了对Rel-14的标准化研究,且正在进行Rel-15的标准化工作。
目前,3GPP基于对第五代通信技术(the 5 Generation Mobile Communication Technology,5G)系统的研究已经开始,在5G系统的新技术框架下对V2X通信技术的增强研究也被提上日程。在这种情况下,需要LTE系统的V2X通信技术与5G系统的V2X通信技术有效共存,以避免由于不共存而导致的车车之间无法互联互通的问题。但是,目前还不存在如何实现LTE系统的V2X通信技术与5G系统的V2X通信技术有效共存的方法。

具体实施方式
车联网是指通过装载在车辆上的传感器、装置、芯片、车载终端或电子标签提供车辆信息,采用各种通信技术实现V2V、V2P、V2I的互联互通,并在信息网络平台上对信息进行提取、共享等有效利用,对车辆进行有效的管控和提供综合服务的系统。
上述V2V、V2P、V2I可以统称为V2X通信技术。LTE系统中的V2X通信技术包括版本14(Rel-14)和版本15(Rel-15)。
目前,市场上已经出现了支持LTE系统的V2X通信技术的车载芯片,试验测试和小规模应用也正在开展之中。而在面向2020年部署的5G系统,也开始了5G系统的V2X通信技术的研究。相应的,研究人员需要考虑5G系统的V2X通信技术与LTE系统的V2X通信技术的共存。若5G系统的V2X通信技术与LTE系统的V2X通信技术无法友好共存,轻则会造成2个系统之间的干扰,降低系统的性能和传输效率。重则会导致2个系统传输的消息不能够被相互识别。一旦因为共存问题导致通信模块的失效,产生重大交通安全事故,这种场景是绝对不能接受的。
目前不存在如何实现LTE系统的V2X通信技术与5G系统的V2X通信技术有效共存的方法。针对该问题,本申请实施例提供一种通信方法,第一通信设备在获取到能够用于传输第一消息和第二消息的第一载波后,获取该第一载波中用于发送第一消息的第一传输资源和用于发送第二消息的第二传输资源,并在第一传输资源上利用第一无线接入技术发送第一消息,在第二传输资源上利用第二无线接入技术发送第二消息。这里,第一传输资源和第二传输资源不同,第一无线接入技术与第二无线接入技术为不同的设备间直连通信技术。
由于第一无线接入技术和第二接入网技术不同,第一传输资源和第二传输资源不同,因此,第一通信设备既可以根据第一无线接入技术通过第一传输资源发送第一消息,还可以根据第二无线接入技术通过第二传输资源发送第二消息,实现了两种不同类型的业务的共存。相应的,若第一无线接入技术为5G系统的V2X通信技术,第二无线接入技术为LTE系统的V2X通信技术,采用本申请提供的通信方法即可实现LTE系统的V2X通信技术与5G系统的V2X通信技术的有效共存。
本申请实施例提供的通信方法适用于通信系统,该通信系统支持不同类型的业务数据的传输。
图1是本申请实施例提供的通信系统的一种结构示意图。参见图1,该通信系统包括远端设备10、中继设备11以及全球导航卫星系统(Global Navigation Satellite System,GNSS)12。远端设备10可以通过中继设备11与GNSS 12通信,也可以直接与GNSS 12通信。
远端设备10与中继设备11之间的连接可以为3GPP连接,也可以为非3GPP连接。3GPP连接的具体连接方式可以采用设备到设备(Device to Device,D2D)/V2X通信技术。非3GPP连接的具体连接方式可以采用蓝牙(Bluetooth,BT)、无线保真(Wireless Fidelity,Wi-Fi)、近场通信(Near Field Communication,NFC)和红外线等无线短距离通信技术中的任意一种,本申请实施例对此不作具体限定。
本申请实施例的远端设备10可以为物联网中的终端,例如智能水表、智能电表等,也可以为车联网中装载在车辆上的车载终端,还可以为智能穿戴设备,例如可穿戴式设备(Wearable Device,WD)。
本申请实施例的中继设备11是具备中继属性的终端。该终端自身可以提供D2D、BT、Wi-Fi、NFC、红外线等各种可用网络连接能力的无线终端。
可选的,图1示出的通信系统还可以包括基站13。
该基站13可以为下一代LTE基站(Next Generation eNB,ng-eNB),也可以为gNB(5G系统中的基站),本申请实施例对此不作具体限定。ng-eNB可以通过演进 通用陆地无线接入(Evolved Universal Terrestrial Radio Access,E-UTRA)技术为终端提供无线传输资源,也可以为终端提供第五代核心网(the 5th Generation Core Network,5GCN)的服务。
基站13可以为远端设备10和/或中继设备11提供服务。基站13还可以与GNSS12通信。远端设备10可以通过中继设备11与基站13通信,也可以直接与基站13通信。在实际应用中,为远端设备10提供服务的基站与为中继设备11提供服务的基站可以相同也可以不同。
可选的,当上述通信系统应用于车联网场景时,该通信系统还可以包括路侧单元(Road Side Unit,RSU)14。RSU 14可与远程设备10、中继设备11以及基站13通信。RSU 14可以具备装载在车辆上的车载终端的功能,也可以具备基站的功能。
图1中的任一设备可支持LTE业务数据和5G业务数据的传输。
在实际应用中,上述多个设备之间的连接为无线连接,为了方便直观地表示各个设备之间的连接关系,图1采用实线示意。
需要说明的是,图1仅仅是对本申请实施例提供的通信系统的举例说明,并不是对该通信系统的具体限定。在实际应用中,该通信系统还可以包括至少一个中继设备、至少一个RSU以及至少一个基站。
在本申请的通信系统包括基站的场景中,远端设备可以位于基站的网络覆盖范围内,并直接与基站建立无线资源控制(Radio Resource Control,RRC)连接或者接收基站发送广播消息,但与基站之间进行数据传输时,需要通过中继设备进行转发。例如,结合图1,如图2所示,远端设备20位于基站gNB 1的网络覆盖范围内,可以通过中继设备21与gNB 1进行数据传输,通过中继设备22与gNB 2进行数据传输。
此外,远端设备还可以位于基站的网络覆盖范围外,接收来自基站网络覆盖范围内的中继设备发送的信号。例如,结合图1,如图3所示,远端设备30位于gNB 1和gNB 2的网络覆盖范围外,可以同时接收处于gNB 1和gNB 2的网络覆盖范围内的中继设备31和中继设备32发送的信号。
图4是本申请实施例提供的通信系统的另一种结构示意图。参见图4,该通信系统包括基站40、基站41以及基站42。基站40与基站41和基站42均连接,基站41与基站40和基站42也均连接。基站41、基站40以及基站42可以均为宏站,也可以均为微站,还可以一部分为宏站,另一部分为微站。图4中的任一基站可支持LTE业务数据和5G业务数据的传输。
同理,在实际应用中,上述基站之间的连接为无线连接,为了方便直观地表示各个基站之间的连接关系,图4采用实线示意。
需要说明的是,图4仅仅是对本申请实施例提供的通信系统的举例说明,并不是对该通信系统的具体限定。在实际应用中,每一基站还可以为至少一个终端提供服务。
本申请实施例中的远端设备和中继设备均可以为能够与基站在控制面和用户面实现数据传输的终端,该终端可以为手机(如图5所示的手机300)、平板电脑、个人计算机(Personal Computer,PC)、个人数字助理(Personal Digital Assistant,PDA)、智能手表、上网本、可穿戴电子设备等。

由于上述触摸屏306、蓝牙装置307、一个或多个传感器308、无线保真(Wireless Fidelity,Wi-Fi)装置309、定位装置310以及音频电路311为可选的部件,图5中用虚线框表示。
下面结合图5对手机300的各个部件进行具体的介绍:
处理器301是手机300的控制中心,利用各种接口和线路连接手机300的各个部分,通过运行或执行存储在存储器303内的应用程序,以及调用存储在存储器303内的数据,执行手机300的各种功能和处理数据。在一些实施例中,处理器301可包括一个或多个处理单元。在本申请实施例一些实施例中,上述处理器301还可以包括指纹验证芯片,用于对采集到的指纹进行验证。

触摸屏306具体可以包括触控板306-1和显示器306-2。
其中,触控板306-1可采集手机300的用户在其上或附近的触摸事件(比如用户使用手指、触控笔等任何适合的物体在触控板306-1上或在触控板306-1附近的操作),并将采集到的触摸信息发送至其他器件(例如处理器301)。其中,用户在触控板306-1附近的触摸事件可以称之为悬浮触控;悬浮触控可以是指,用户无需为了选择、移动或拖动目标(例如图标等)而直接接触触控板,而只需用户位于设备附近以便执行所想要的功能。此外,可以采用电阻式、电容式、红外线以及表面声波等多种类型来实现触控板306-1。
显示器(也称为显示屏)306-2可用于显示由用户输入的信息或提供给用户的信息以及手机300的各种菜单。可以采用液晶显示器、有机发光二极管等形式来配置显示器306-2。触控板306-1可以覆盖在显示器306-2之上,当触控板306-1检测到在其上或附近的触摸事件后,传送给处理器301以确定触摸事件的类型,随后处理器301可以根据触摸事件的类型在显示器306-2上提供相应的视觉输出。虽然在图5中,触控板306-1与显示器306-2是作为两个独立的部件来实现手机300的输入和输出功能,但是在某些实施例中,可以将触控板306-1与显示器306-2集成而实现手机300的输入和输出功能。可以理解的是,触摸屏306是由多层的材料堆叠而成,本申请实施例实施例中只展示出了触控板(层)和显示器(层),其他层在本申请实施例实施例中不予记载。另外,触控板306-1可以以全面板的形式配置在手机300的正面,显示器306-2也可以以全面板的形式配置在手机300的正面,这样在手机的正面就能够实现无边框的结构。
可选的,手机300还可以具有指纹识别功能。例如,可以在手机300的背面(例如后置摄像头的下方)配置指纹采集器件312,或者在手机300的正面(例如触摸屏306的下方)配置指纹采集器件312。又例如,可以在触摸屏306中配置指纹采集器件312来实现指纹识别功能,即指纹采集器件312可以与触摸屏306集成在一起来实现手机300的指纹识别功能。在这种情况下,该指纹采集器件312配置在触摸屏306中,可以是触摸屏306的一部分,也可以以其他方式配置在触摸屏306中。本申请实施例实施例中的指纹采集器件312的主要部件是指纹传感器,该指纹传感器可以采用任何类型的感测技术,包括但不限于光学式、电容式、压电式或超声波传感技术等。

定位装置310,用于为手机300提供地理位置。
可以理解的是,该定位装置310具体可以是全球定位系统(Global Positioning System,GPS)或北斗卫星导航系统、俄罗斯GLONASS等定位系统的接收器。定位装置310在接收到上述定位系统发送的地理位置后,将该信息发送至处理器301进行处理,或者发送至存储器303进行保存。
在另外的一些实施例中,该定位装置310还可以是辅助全球卫星定位系统(Assisted Global Positioning System,AGPS)的接收器,AGPS系统通过作为辅助服务器来协助定位装置310完成测距和定位服务,在这种情况下,辅助定位服务器通过无线通信网络与设备例如手机300的定位装置310(即GPS接收器)通信而提供定位协助。
在另外的一些实施例中,该定位装置310也可以是基于Wi-Fi接入点的定位技术。由于每一个Wi-Fi接入点都有一个全球唯一的MAC地址,设备在开启Wi-Fi的情况下即可扫描并收集周围的Wi-Fi接入点的广播信号,因此可以获取到Wi-Fi接入点广播出来的MAC地址;设备将这些能够标示Wi-Fi接入点的数据(例如MAC地址)通过无线通信网络发送至位置服务器,由位置服务器检索出每一个Wi-Fi接入点的地理位置,并结合Wi-Fi广播信号的强弱程度,计算出该设备的地理位置并发送到该设备的定位装置310中。
音频电路311、扬声器313、麦克风314可提供用户与手机300之间的音频接口。音频电路311可将接收到的音频数据转换后的电信号,传输到扬声器313,由扬声器313转换为声音信号输出;另一方面,麦克风314将收集的声音信号转换为电信号,由音频电路311接收后转换为音频数据,再将音频数据输出至RF电路302以发送至比如另一手机,或者将音频数据输出至存储器303以便进一步处理。
尽管图5未示出,手机300还可以包括摄像头(前置摄像头和/或后置摄像头)、闪光灯、微型投影装置、NFC装置等,在此不再赘述。
本领域技术人员可以理解,图5中示出的硬件结构并不构成对手机的限定,手机300可以包括比图示更多或更少的部件,或者组合某些部件,或者不同的部件布置。

在具体的实现中,作为一种实施例,处理器61可以包括一个或多个CPU,例如图中所示的CPU 0和CPU 1。处理器61可以是一个单核处理器(single-CPU),也可以是一个多核处理器(multi-CPU)。这里的处理器可以指一个或多个设备、电路、和/或用于处理数据(例如计算机程序指令)的处理核。
存储器62可以是只读存储器(Read-Only Memory,ROM)或可存储静态信息和指令的其他类型的静态存储设备,随机存取存储器(Random Access Memory,RAM)或者可存储信息和指令的其他类型的动态存储设备,也可以是电可擦可编程只读存储器(Electrically Erasable Programmable Read-Only Memory,EEPROM)、只读光盘(Compact Disc Read-Only Memory,CD-ROM)或其他光盘存储、光碟存储(包括压缩光碟、激光碟、光碟、数字通用光碟、蓝光光碟等)、磁盘存储介质或者其他磁存储设备、或者能够用于携带或存储具有指令或数据结构形式的期望的程序代码并能够由计算机存取的任何其他介质,但不限于此。存储器62可以是独立存在,通过总线63与处理器61相连接。存储器62也可以和处理器61集成在一起。
其中,存储器62用于存储执行本申请方案的软件程序,并由处理器61来控制执行。
总线63,可以是工业标准体系结构(Industry Standard Architecture,ISA)总线、外部设备互连(Peripheral Component Interconnect,PCI)总线或扩展工业标准体系结构(Extended Industry Standard Architecture,EISA)总线等。该总线可以分为地址总线、数据总线、控制总线等。为便于表示,图6中仅用一条粗线表示,但并不表示仅有一根总线或一种类型的总线。
可选的,基站还包括收发器64。收发器64用于在处理器61的控制下与其他设备或通信网络通信。如用于与以太网,无线接入网(Radio Access Network,RAN),无线局域网(Wireless Local Area Networks,WLAN)等通信网络通信。收发器64可以包括基带处理器的全部或部分,以及还可选择性地包括RF处理器。RF处理器用于收发RF信号,基带处理器则用于实现由RF信号转换的基带信号或即将转换为RF信号的基带信号的处理。
由于收发器64为可选的,因此,图6中用虚线表示。
图6中示出的设备结构并不构成对基站的限定,可以包括比图示更多或更少的部件,或者组合某些部件,或者不同的部件布置。
以下,结合上述图1示出的通信系统、图4示出的通信系统、图5示出的手机300以及图6示出的基站对本申请提供的通信方法进行详细描述。
图7为本申请实施例中通信方法的一种流程示意图,该通信方法可以应用于图1或图4示出的通信系统中。
图7示出的流程以执行主体为第一通信设备为例进行说明。该第一通信设备属于发送端设备,具体可以为上述远端设备、中继设备、RSU或基站,当然也可以为上述任一设备中的芯片,本申请实施例对此不作具体限定。
如图7所示,本申请实施例提供的通信方法包括:
S700、第一通信设备获取用于传输第一消息和第二消息的第一载波。
这里,第一消息或第二消息可以为包括控制信息的消息,也可以为参数信号,还 可以为其他类型的消息,本申请实施例对此不作具体限定。
本申请实施例中的第一消息采用第一无线接入技术传输,第二消息采用第二无线接入技术传输,第一无线接入技术和第二无线接入技术为不同的设备间直连通信技术。例如:第一无线接入技术为下一代接入网(New Radio,NR)中的设备间直连通信技术,即为5G系统的V2X通信技术,第二无线接入技术为LTE系统的V2X通信技术。
在设备间直连通信技术中,设备到设备之间的链路可以被称为D2D链路,也可被称为边链路(Sidelink)。D2D链路/边链路中不同设备之间的传输方式可以是基于广播、组播或单播传输方式中的任意一种,本申请实施例对此不作限定。
此外,本申请实施例中的第二无线接入技术还可以为终端与接入网设备(如基站)之间的无线接入技术。
若第一无线接入技术为NR中的设备间直连通信技术,第二无线接入技术为终端与接入网设备之间的无线接入技术,则本申请提供的通信方法适用于在蜂窝链路上实现传输资源的共享/共存。
本申请实施例中的第一载波可以为预配置的,也可以是网络设备通过载波配置指示信息指示的,本申请实施例对此不作具体限定。若第一载波为预配置的,则第一通信设备直接确定第一载波。若第一载波为网络设备通过载波配置指示信息指示的,则第一通信设备接收来自网络设备的用于指示第一载波的载波指示信息,并根据载波指示信息,获取第一载波。
S701、第一通信设备获取第一载波的第一传输资源和第二传输资源。
容易理解的是,由于第一载波用于第一消息和第二消息的传输,且第一通信设备采用不同的无线接入技术传输第一消息和第二消息,因此,第一消息和第二消息可承载于不同的传输资源。
本申请实施例中发送第一消息的传输资源为第一传输资源,发送第二消息的传输资源为第二传输资源,第一传输资源和第二传输资源不同。
其中,第一传输资源的子载波间隔与第二传输资源的子载波间隔相互独立。也就是说,第一传输资源的子载波间隔和第二传输资源的子载波间隔可以分别配置或者分别定义。在实际应用中,第一传输资源的子载波间隔和第二传输资源的子载波间隔可以相等,也可以不等。
此外,第一传输资源与第二传输资源在时域上具有相同的无线帧号,如第一传输资源与第二传输资源的直接帧号(Direct Frame Number,DFN)相同。或者,第一传输资源与第二传输资源在时域上无线帧号之间存在预设偏差值。该预设偏差值可以是预先定义好的,也可以是网络设备通过信令指示的。示例性的,预设偏差值为第一传输资源的时隙长度的N倍,N为正整数。
由于第一传输资源与第二传输资源在时域上具有相同的无线帧号,或者,第一传输资源与第二传输资源在时域上无线帧号之间存在预设偏差值,因此,本申请实施例可以以无线帧为单位对齐第一传输资源和第二传输资源的定时。这样,能够减少第一传输资源和第二传输资源在时域上复用的资源浪费。例如,如果第一传输的无线帧号与第二传输的无线帧号没有对齐,则它们的定时在时间上会有部分的重叠,在这部分重叠的资源上,不能实现第一传输资源与第二传输资源的正交复用。从而造成资源的 浪费。
其中,本申请实施例中时隙的时长(即时隙长度)是指一次传输占用的最基本的时长。该时隙长度可以是预先定义的,例如:时隙长度为1毫秒,或0.5毫秒,或0.25毫秒,或0.125毫秒,也可以是根据参考时隙的时长以及实际传输过程中的子载波间隔确定的。
当第一传输资源的子载波间隔比第二传输资源的子载波间隔大时,第一传输资源的时隙长度小于第二传输资源的时隙长度。例如,若第一传输资源用于传输5G系统的V2X通信技术的业务数据,其子载波间隔为30KHz或者60KHz,第二传输资源用于传输LTE系统的V2X通信技术的业务数据,其子载波间隔为15KHz时,第一传输资源的时隙长度小于第二传输资源的时隙长度。
一种实现方式中,第一传输资源和第二传输资源均属于第一载波的同一资源池,例如:第一传输资源和第二传输资源均属于第一资源池。在这种情况下,可选的,第一传输资源和第二传输资源正交。此处的正交,即为占用的频域资源不同。例如:第一资源池占用的子载波、物理资源块、占用的子信道,或占用的载波中的带宽部分与第二资源池不同。此时,第一传输资源上5G系统的V2X业务可以与第二传输资源上LTE系统的V2X业务可以实现相互不干扰的正交传输。从而达到两种业务友好的共存。
在另一种实现方式中,第一传输资源和第二传输资源分别属于第一载波的不同资源池。例如:第一传输资源属于第二资源池,第二传输资源属于第三资源池。在这种情况下,可选的,第二资源池和第三资源池正交。
可选的,第一通信设备可以采用FDM的方式占用第一传输资源和第二传输资源(如图8所示),也可以采用TDM的方式占用第一传输资源和第二传输资源(如图9A或图9B所示),本申请实施例对此不作具体限定。
可选的,在第一通信设备采用TDM的方式占用第一传输资源和第二传输资源的场景中,第一通信设备获取第一载波的第一传输资源的方法可以为:第一通信设备获取第一载波的第一资源集,该第一资源集的时域资源单元是由第一传输资源的子载波间隔确定的,这样,第一通信设备可根据第一配置信息,从第一资源集中获取第一传输资源,第一配置信息用于指示第一资源集中的至少一个时域资源单元。第一配置信息是由网络设备发送的第二信令所指示的或者是预配置的。
可选的,在第一通信设备采用TDM的方式占用第一传输资源和第二传输资源的场景中,第一通信设备获取第一载波的第二传输资源的方法可以为:第一通信设备获取第一载波的第二资源集,该第二资源集的时域资源单元是由第二传输资源的子载波间隔确定的,这样,第一通信设备可根据第二配置信息,从第二资源集中获取第二传输资源,第二配置信息用于指示第二资源集中的至少一个时域资源单元。第二配置信息是由网络设备发送的第三信令所指示的或者是预配置的。
可选的,可以将上述时域资源单元简单的理解为时隙。
如图9A所示,若第一传输资源的子载波间隔为30KHz,第二传输资源的子载波间隔为15KHz,第一通信设备根据网络设备发送的信令或预先配置,获取第一资源集,并根据第一配置信息从第一资源集中获取第一传输资源。此外,第一通信设备根据网络设备发送的信令或预先配置,获取第二资源集,并根据第二配置信息从第二资源集 中获取第二传输资源。
可选的,在第一通信设备采用TDM的方式占用第一传输资源和第二传输资源的场景中,第一通信设备获取第一载波的第一传输资源的方法也可以为:第一通信设备获取第三资源集和第四资源集,该第四资源集为第三资源集的子集,第三资源集的时域资源单元是由第二传输资源的子载波间隔确定的,第四资源集的时域资源单元是由第一传输资源的子载波间隔确定的,这样,第一通信设备根据第三配置信息,从第四资源集中获取所述第一传输资源,该第三配置信息用于指示第四资源集中的至少一个时域资源单元。这里,第三配置信息是由网络设备发送的第四信令所指示的或者是预配置的。也就是说,第一通信设备首先从第三资源集中确定第四资源集,然后从该第四资源集中确定第一传输资源。由于第三资源集是由第二传输资源的子载波间隔确定,因此,第二传输资源的子载波间隔可以理解为参考子载波间隔。此时,第一通信设备可以根据第四配置信息获取第二传输资源,该第四配置信息是由网络设备发送的第五信令所指示的或者是预配置的。
如图9B所示,若第二传输资源的子载波间隔为参考子载波间隔,其数值为30KHz,第一传输资源的子载波间隔为15KHz,第一通信设备根据网络设备发送的信令或预先配置,获取第三资源集和第四资源集,并根据第三配置信息从第四资源集中获取第一传输资源。
需要说明的是,第一通信设备可以先确定第二传输资源,后确定第一传输资源,也可以先确定第一传输资源,后确定第二传输资源,还可以同时确定第一传输资源和第二传输资源,本申请实施例对此不作具体限定。
S702、第一通信设备在第一传输资源上利用第一无线接入技术发送第一消息,在第二传输资源上利用第二无线接入技术发送第二消息。
在获取到第一传输资源后,第一通信设备在第一传输资源上利用第一无线接入技术发送第一消息。在获取到第二传输资源后,第一通信设备在第二传输资源上利用第二无线接入技术发送第二消息。
从上面描述可知,第一传输资源和第二传输资源为第一载波中的不同传输资源。一般的,不同传输资源对应的发送功率不同。因此,第一通信设备可根据第一无线接入技术在第一传输资源上采用第一发送功率发送第一消息,并根据第二无线接入技术在第二传输资源上采用第二发送功率发送第二消息。其中,本申请中的发送功率是指第一通信设备在第一传输资源或第二传输资源上发送消息所耗费的功率。
第一发送功率与第二发送功率的和小于或等于配置功率。这里,配置功率可以为第一通信设备的最大发送功率或者最大可用发送功率,也可以为当前子帧上所有载波的最大发送功率或者最大可用发送功率,还可以为当前子帧中当前载波上的最大发送功率或最大可用发送功率,还可以为当前信道(数据信道/控制信道)上配置或指示的最大发送功率。除此之外,配置功率还可以为预先定义的,或者为基站通过信令配置的,本申请实施例对此不作具体限定。
可选的,第一发送功率是第一通信设备根据第一消息的优先级确定的,第二发送功率是第一通信设备根据第二消息的优先级确定的;或者,第一发送功率或第二发送功率是网络设备通过信令配置的,或者,第一发送功率或第二发送功率是预先配置好 的。
容易理解的是,在第一通信设备采用FDM方式占用第一传输资源和第二传输资源的场景中,若某一时隙,第一通信设备未传输第二消息,且传输了第一消息(或者为某一时隙,存在第一传输资源而不存在第二传输资源),则第一发送功率可等于配置功率。若某一时隙,第一通信设备既传输了第一消息,又传输了第二消息(或者为某一时隙,存在第一传输资源和第二传输资源),则第一通信设备可根据第一消息的优先级确定第一发送功率,根据第二消息的优先级确定第二发送功率。
如图8所示,t1时刻,第一通信设备传输了第一消息,未传输第二消息,则该时刻第一发送功率为配置功率,第二发送功率为零。t2时刻,第一通信设备传输了第一消息和第二消息,则该时刻第一发送功率和第二发送功率均小于配置功率,且第一发送功率与第二发送功率的和小于配置功率。
可选的,第一消息的优先级或第二消息的优先级可以是预先定义的,也可以是网络设备配置的。示例性的,针对不同业务,预先定义的优先级为:高可靠低时延通信(Ultra Reliable Low Latency Communication,URLLC)的优先级高于V2X的优先级,V2X的优先级高于增强移动带宽(Enhance Mobile Broadband,eMBB)的优先级,eMBB的优先级高于海量机器类通信(massive Machine Type of Communication,mMTC)的优先级。
在一种示例中,在第一通信设备的发送功率受限或者蜂窝链路的业务与V2X的业务在时间上有重叠的场景中,V2X传输与蜂窝链路的以下信号有重叠或冲突时,第一通信设备按照下述优先级发送信道或参考信号:
方式一:用于边链路上波束测量的参考信号(Sidelink Beam Reference Signal,SBRS)具有最高的优先级,其他的参考信号或信道具有次低的优先级,例如:边链路波束参考信号(Sidelink Beam Reference Signal,SBRS)的优先级高于同步信号块(Synchronization Signal Block,SSB)的优先级,SSB的优先级高于物理随机接入信道(Physical Random Access Channel,PRACH)的优先级,PRACH的优先级高于探测参考信号(Souding Reference Signal,SRS)的优先级,SRS的优先级高于解调参考信号(Demodulation Reference Signal,DMRS)的优先级。
方式二:第一通信设备根据基站的指示信息确定SBRS、PRACH以及SRS之间的优先级。
方式三:第一通信设备根据预定义的方式确定参考信号间的优先级。例如:SBRS具有最高的优先级,SSB具有第二优先级;或者,SSB最有最高优先级,SBRS具有第二优先级;或者,SRS/PRACH的优先级高于SBRS的优先级,SBRS的优先级高于短物理上行控制信道(shortened Physical Uplink Contorl Channel,sPUCCH)的优先级;或者,sPUCCH的优先级高于SBRS的优先级。
从前面描述可知,第一传输资源的子载波间隔越大,第一传输资源的符号或时隙长度就越短。第一传输资源的符号或时隙长度就越短,对第一消息的传输造成的影响就会越小,因此,第一通信设备分配的第一发送功率就越大。此外,第一传输资源的子载波间隔越大,第一传输资源具有的时间分集就会越小,因此,第一通信设备需要更大的发送功率以抵消分集增益的下降。这样,本申请实施例中的第一发送功率与第 一传输资源的子载波间隔成正相关关系,也就是说,第一传输资源的子载波间隔越大,第一发送功率越大。
可选的,第一通信设备可以根据下述公式(1)或公式(2)确定第一发送功率和第二发送功率。
Figure PCTCN2019090032-appb-000001
Figure PCTCN2019090032-appb-000002
其中,P1表示第一发送功率,P2表示第二发送功率,P0表示配置功率,u1表示第一传输资源的子载波间隔,u2表示第二传输资源的子载波间隔,a1和b1均为非负常数。
当然,上述公式(1)或公式(2)还可以采用其他形式表示,如对数公式。
此外,第一通信设备发送第一消息采用的同步参考源和第一通信设备发送第二消息采用的同步参考源的类型相同;或者,第一通信设备发送第一消息采用的同步参考源传输资源和第一通信设备发送第二消息采用的同步参考源相同。这样,第一消息和第二消息的传输能够保持相同的定时,避免了由于定时不同而导致在消息传输过程中的相互干扰。
可选的,第一通信设备可向同一设备发送第一消息和第二消息,也可将第一消息和第二消息发送至不同设备。
可选的,第一通信设备在发送第一消息的同时,还可以发送用于指示第一发送功率的第一指示信息。在发送第二消息的同时,第一通信设备还可以发送用于指示第二发送功率的第二指示信息。

可选的,第一通信设备可以同时发送第四指示信息和第二消息,也可以分别发送第四指示信息和第二消息,本申请实施例对此不作具体限定。同理,在第一通信设备发送第二指示信息和第四指示信息的场景中,第一通信设备可以同时发送第二指示信息和第四指示信息,也可以分别发送第二指示信息和第四指示信息,本申请实施例对此不作具体限定。
可选的,若第一通信设备从第四资源集中获取第一传输资源,则第一通信设备在发送第一消息的情况下,还可以发送用于指示第三资源集的第五指示信息以及用于指示第四资源集的第六指示信息。第一通信设备在发送第二消息的情况下,还可以发送第五指示信息。

需要说明的是,若第一通信设备向同一设备发送第一消息和第二消息,则第一通信设备只需执行S1300即可。
从上面描述可知,由于第一无线接入技术和第二接入网技术不同,且第一传输资源和第二传输资源不同,因此,第一通信设备既可以根据第一无线接入技术通过第一传输资源发送第一消息,还可以根据第二无线接入技术通过第二传输资源发送第二消息,实现了两种不同类型的业务的共存。这里相互独立是指第一传输资源的子载波间隔和第二传输资源的子载波间隔是分别配置的,它们的取值没有关联的关系。
具体的,若第一无线接入技术为5G系统的V2X通信技术,第二无线接入技术为LTE系统的V2X通信技术,采用本申请提供的通信方法即可实现5G系统的V2X通信技术与LTE系统的V2X通信技术的有效共存。

综上所述,本申请提供的通信方法实现了不同类型的业务的共存。
