本申请要求于2018年11月02日提交中国专利局、申请号为201811300738.4、申请名称为“通信方法和通信装置”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
本申请实施例涉及通信领域,并且更具体地,涉及一种通信方法和通信装置。
无线通信技术在过去几十年经历了飞速的发展,先后经历了基于模拟通信系统的第一代无线通信系统,以全球移动通信系统(global system for mobile communication,GSM)为代表的2G无线通信系统,以宽带码分多址(wideband code division multiple access,WCDMA)为代表的3G无线通信系统,再到现在已经在全世界广泛商用并且取得巨大成功的长期演进(long term evolution,LTE)无线通信系统。无线通信系统支持的业务也从最初的语音、短信,发展到现在支持无线高速数据通信。与此同时,全世界范围内的无线连接数量正在经历持续地高速增长,各种新的无线业务类型也大量涌现,例如物联网、智能交通等,这些都对无线通信系统提出了更高的要求。
基于蜂窝网络的设备对设备(device to device,D2D)通信,是一种在系统的控制下,允许终端之间通过复用小区资源直接进行通信的新型技术,它能够增加蜂窝通信系统频谱效率,降低终端发射功率,在一定程度上解决无线通信系统频谱资源匮乏的问题。
为了提升交通系统的安全性和智能化,智能交通的系统理念逐渐兴起。近阶段,智能交通系统的开发将主要集中在智能公路交通系统领域,也就是俗称的车联网(vehicle to everything,V2X)。车对车(vehicle to vehicle,V2V)、车对行人(vehicle to pedestrian,V2P)与车对基础设施(vehicle to infrastructure,V2I)统称为V2X,这些技术允许汽车与所有附近其它汽车及道路基础设施进行连续通信,比如与红绿灯、校区和铁路道口等设施之间通信。在车联网系统中,终端设备之间进行通信时,通常采用的资源分配模式有两种,一种是网络设备对资源进行调度,一种是终端设备自主选择资源。当终端设备自主选择资源时,需要先监听(sensing)资源以识别可用资源,然后在可用资源中选择资源进行数据传输,这一过程中会产生比较大的时延。

下面将结合附图,对本申请中的技术方案进行描述。
应理解,本申请实施例的技术方案,可以应用于各种通信系统,例如:全球移动通讯系统(global system of mobile communication,GSM),码分多址(code division multiple access,CDMA)系统,宽带码分多址(wideband code division multiple access wireless,WCDMA),通用分组无线业务(general packet radio service,GPRS),长期演进(long term evolution,LTE),新无线(new radio,NR)等。
还应理解,在本申请实施例中,终端设备也可以指用户设备(user equipment,UE)、接入终端、用户单元、用户站、移动站、移动台、远程终端、移动设备、用户终端、终端、 无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol,SIP)电话、无线本地环路(wireless local loop,WLL)站、个人数字处理(personal digital assistant,PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备,未来5G网络中的终端设备或者未来演进的公共陆地移动网络(public land mobile network,PLMN)网络中的终端设备等。
应理解,本申请实施例中,终端设备可以是安装在汽车里面的通信终端或车载通信设备,还可以是其它能够实现通信功能的模块化、可拆卸的车载终端。终端设备在功能上要能够实现车对车(vehicle to vehicle,V2V)、车对行人(vehicle to pedestrain,V2P)、车与基础设施(vehicle to infrastucture,V2I)等业务的信息通讯,这些业务可以统称为V2X业务。因此,本申请实施例中的V2X业务可以包括以下业务中的一种或多种:V2V业务、V2I业务、车与人V2P业务。
在某些实施例中,本申请提及的终端设备还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备,是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称,如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上,或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备,更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能,例如:智能手表或智能眼镜等,以及只专注于某一类应用功能,需要和其它设备如智能手机配合使用,如各类进行体征监测的智能手环、智能首饰等。
应理解,在本申请实施例中,网络设备可以是位于网络侧与终端设备进行通信的设备,该网络设备可以是GSM或CDMA中的基站收发台(base transceiver station,BTS),也可以是WCDMA系统中的节点B(NodeB,NB),还可以是LTE系统中的演进型节点B(evolutional Node B,eNB或eNodeB),还可以是未来5G网络中的下一代节点B(next generation Node B,gNB),还可以是云无线接入网络(cloud radio access network,CRAN)场景下的无线控制器,或者该网络设备可以为中继站、接入点以及未来5G网络中的网络设备或者未来演进的公共陆地移动网络(public land mobile network,PLMN)中的网络设备等。
图1给出了本申请实施例应用的一种通信系统100的示意图。在图1的应用场景中,通信系统100可以包括网络设备101以及终端设备102、103、104、105和106,其中,网络设备与终端设备之间、终端设备与终端设备之间都可以通过无线连接。应理解,图1仅以系统包括5个终端设备为例进行说明,但本申请实施例并不限于此,例如,通信系统100还可以包括更多的终端设备;类似地,系统也可以包括更多的网络设备,本申请实施例对此并不限定。
图1所示的应用场景中,终端设备之间可以进行D2D通信,终端设备与终端设备之间的通信链路可以称为侧行链路(sidelink)。第三代合作伙伴计划(3rd generation partnership project,3GPP)的版本14(release14)定义了基于D2D链路增强的V2X链路(例如,可以包括以下链路中的至少一种:V2V、V2I、V2P链路)。D2D链路和V2X链路可以采用不同的接口进行通信。
如图1所示,D2D通信可以分为有网络覆盖、部分网络覆盖和没有网络覆盖3种。例如,图1中的终端设备102在网络设备101的覆盖范围内,可以接收网络设备101的信号,即终端设备102有网络覆盖,可以称为网络覆盖内终端设备;终端设备103不在网络设备101的覆盖范围内,但终端设备103可以接收网络覆盖内的终端设备102的信号,因此,终端设备103为部分网络覆盖,可以称为部分网络覆盖终端设备;终端设备104、105和106不在网络设备101的覆盖范围内,且终端设备104、105和106也无法接收网络覆盖内的终端设备102的信号,此时,终端设备104、105和106没有网络覆盖,可以称为网络覆盖外终端设备。
终端设备在sidelink上可以有两种资源分配的方式,一种是模式3(mode 3),网络设备对终端设备进行资源分配,另一种是模式4(mode 4),终端设备自主选择可用资源。通常,网络系统中可以包括不止一个终端设备,其中,有网络覆盖的终端设备可以采用mode 3,如图1中的终端设备102;没有网络覆盖的终端设备可以采用mode 4,如图1中的终端设备104、105和106。现有技术中,采用mode 4的终端设备可以通过竞争的方式从资源池中获得发送资源,其中,资源池可以是网络设备配置的,或预先配置的一块资源,mode 4的终端设备可以在所述资源池中竞争资源。终端设备在传输数据之前需要监听资源,以识别可用资源及不可用资源,然后在可用资源中选择资源进行数据传输。由于终端设备是通过竞争方式获得资源,出现两个或两个以上的终端设备选择到同一块资源的概率比较大,容易产生冲突。因此,数据传输过程中会产生比较大的时延。
基于此,本申请实施例提出了一种通信方法,能够降低数据传输的时延,提高系统的通信效率。图2为本申请实施例提供的一种通信方法的示意性流程图。
图2所示的通信方法可以包括步骤210、步骤220、步骤230和步骤240。
S210,第一终端设备确定第一参数,所述第一参数用于指示监听窗的参数、资源选择窗的参数和/或第一时间窗的参数,所述第一时间窗包括监听窗和资源选择窗。
其中,所述第一时间窗包括监听窗和资源选择窗,可以理解为,所述第一时间窗的时长不小于监听窗和资源选择窗的总和。也就是说,所述第一时间窗内包括监听窗和资源选择窗。
在本申请实施例一种可能的实现方式中,所述第一参数可以包括以下参数中的至少一种:监听窗的起始时间、监听窗的结束时间、监听窗的长度、资源选择窗的起始时间、资源选择窗的结束时间、资源选择窗的长度、第一时间窗的起始时间、第一时间窗的结束时间或第一时间窗的长度。
S220,所述第一终端设备根据所述第一参数从至少一个资源池中确定第一资源池。
其中,所述至少一个资源池中的一个资源池可以具有对应的时间窗参数,所述第一资源池所对应的时间窗参数为所述第一参数。
在本申请实施例一种可能的实现方式中,所述至少一个资源池可以为一个资源池,此时,所述第一终端设备可以选取该资源池作为第一资源池。
在本申请实施例中,所述至少一个资源池中的一个资源池具有对应的时间窗参数,可以理解,所述至少一个资源池中的一个资源池与所述时间窗参数一一对应。
如图3所示,在传输数据之前,所述第一终端设备可以在监听窗(sensing window)进行监听,以识别可用资源及不可用资源,然后在资源选择窗(selection window)中选择 资源进行数据传输。如图3所示,所述监听窗的起始时间为n-a,结束时间为n-b,所述资源选择窗的起始时间为n+T1,结束时间为n+T2,其中,n、a、b、T1和T2都是正整数,且n≥a,n>b。
在本申请实施例中,可以预先定义至少一个资源池。例如,所述至少一个资源池可以有各自独立的配置。可选地,所述至少一个资源池中的不同资源池对应的时间窗参数可以不同。
以所述第一参数用于指示资源选择窗,所述第一参数包括资源选择窗的起始时间和结束时间为例,可以预先配置3个资源池,分别对应不同的资源选择窗。例如,假设图3中的资源选择窗对应的T1=5,20≤T2<100,如下表所示,可以预先配置3个资源池,分别对应不同的资源选择窗结束时间。
表1一种可能的资源池配置方法
资源池 | 起始时间 | 结束时间 |
资源池1 | T1=3 | 20≤T2<50 |
资源池2 | T1=3 | 50≤T2<80 |
资源池3 | T1=3 | 80≤T2<100 |
应理解,表1中各个资源选择窗的起始时间可以相同,此时,也可以预先设定所述各个资源选择窗的起始时间。也就是说,所述资源池的时间窗参数可以仅指示资源选择窗的结束时间,通过预先设定的各个资源选择窗的起始时间,所述第一终端设备可以确定所述第一资源池。
可选地,表1中各个资源选择窗的起始时间可以不同。应理解,所述各个资源池对应的监听窗的参数也可以不同,相应地,所述第一时间窗的参数也不同。在本申请实施例中,所述第一参数用于指示监听窗和第一时间窗的情况类似,这里不再赘述。
可选地,所述第一参数可以包括资源选择窗的结束时间。例如,以表1中的资源池配置方法为例,所述第一终端设备可以确定第一参数,即所述资源选择窗的结束时间;所述第一终端设备可以从表1中的3个资源池中选取与所述资源选择窗的结束时间相对应的资源池作为第一资源池,即所述资源选择窗的结束时间在表1中的哪个结束时间的范围内,则将该结束时间对应的资源池作为第一资源池。
在本申请实施例中,第一参数指示的监听窗可以是独立的监听窗,也可以是包括在第一时间窗内的监听窗。第一参数指示的资源选择窗可以是独立的资源选择窗,也可以是包括在第一时间窗内的资源选择窗。
可选地,所述第一参数指示的资源选择窗的时长可以大于或等于所述第一终端设备的处理时延。这里的处理时延可以指所述第一终端设备处理监听结果的时延,或所述第一终端设备准备待发送数据的时延。
可选地,所述第一参数指示的资源选择窗的时长可以小于或等于所述第一资源池的监听窗的时长。
可选地,所述第一参数指示的资源选择窗的时长可以为所述第一资源池的监听窗的时长和所述第一终端设备的业务时延需求对应的时长中的较小值。

在本申请实施例中,所述第一终端设备可以从网络设备接收资源池配置信息,所述资源池配置信息用于指示所述至少一个资源池以及所述至少一个资源池对应的时间窗参数。
在本申请实施例中,所述网络设备可以通过主信息块(master information block,MIB)、系统信息块(system information block,SIB)、无线资源控制(radio resource control,RRC)信令、媒体接入控制(media access control,MAC)层信令、物理层信令(如下行控制信息(downlink control information,DCI))等发送资源池配置消息。
在本申请实施例中,所述网络设备可以向所述第一终端设备发送带宽部分(band width part,BWP)的配置信息或载波(carrier)的配置信息。其中,所述BWP或载波的配置信息中携带所述资源池配置信息。
需要说明的是,本申请实施例中的资源池也可以是BWP。例如,资源池可以是用于侧行传输的BWP。或者,本申请实施例中的资源池可以是BWP中的资源池,或者也可以是载波中的资源池。
可选地,所述网络设备可以为不同的终端设备配置不同的资源池,也可以为多个终端设备配置一个相同的资源池。
可选地,上述资源池配置信息可以指示某一特定时间段内的资源池的时间窗参数,在该时间段后,所述网络设备可以重新向所述第一终端设备发送资源池配置信息。或者,所述网络设备可以在条件触发或动作触发后,重新向所述第一终端设备发送资源池配置信息。
可选地,所述至少一个资源池中的一个第一资源池的监听窗、资源选择窗和/或第一时间窗的时长可以以时隙或符号为单位。
可选地,所述至少一个资源池中的一个第二资源池的监听窗可以为周期性的监听窗,或者所述至少一个资源池中的一个第二资源池的资源选择窗可以为周期性的资源选择窗,或者所述至少一个资源池中的一个第二资源池的第一时间窗可以为周期性的第一时间窗。这里的所述至少一个资源池中的一个第二资源池可以指所述第一资源池。
可选地,监听窗可以位于一个周期的开头。假设周期P=50毫秒(ms),终端设备可以在每50ms的开头10ms进行监听。
可选地,资源选择窗可以位于一个周期的末尾。假设周期P=50ms,终端设备可以在每50ms的末尾10ms进行资源选择。
可选地,资源选择窗时长的最大值可以是监听周期中除了监听窗之外的时间。
监听周期可以由网络设备配置给终端设备,或者终端设备可以根据业务周期设置。
在本申请实施例中,所述第一资源池的资源选择窗的时长可以根据监听结果确定。
在一种可能的实现方式中,所述第一资源池的资源选择窗、或所述第一时间窗内的资源选择窗的时长可以根据监听结果中的可用资源比例确定。如果监听结果中的可用资源比例较小,例如小于或等于20%,则可以选择时长较小的资源选择窗;如果监听结果中的可用资源比例较大,例如大于20%,则可以选择时长较大的资源选择窗。可选地,如果第一终端设备竞争失败,可以增大下一次的资源选择窗的时长;如果第一终端设备竞争成功,可以缩小下一次的资源选择窗的时长。
