Description

无线通信方法和终端设备 技术领域
本申请实施例涉及通信领域,并且更具体地,涉及无线通信方法和终端设备。
背景技术
车联网系统是基于长期演进车辆到车辆(Long Term Evaluation Vehicle to Vehicle,LTE D2D)的一种侧行链路(Sidelink,SL)传输技术,与传统的LTE系统中通信数据通过基站接收或者发送的方式不同,车联网系统采用终端到终端直接通信的方式,因此,具有更高的频谱效率以及更低的传输时延。
在第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)Rel-14中对车联网技术车辆到其他设备(Vehicle to Everything,V2X)进行了标准化,定义了两种传输模式:模式3和模式4。此外,在3GPP Rel-16中,V2X技术被引入到了NR中,除了上述模式3/4(在NR-V2X中被叫做模式1/2),还引入了其他的模式。但是,随着传输需求的增加,单一的传输模式并不能满足数据传输需求。
因此,本领域急需一种数据传输方案,以提高数据传输的效率。

第一方面,提供了一种无线通信方法,包括:

具体实施方式
下面将结合附图,对本申请实施例中的技术方案进行描述。
本申请实施例可以适用于任何终端设备到终端设备的通信框架。
例如,车辆到车辆(Vehicle to Vehicle,V2V)、车辆到其他设备(Vehicle to Everything,V2X)、终端到终端(Device to Device,D2D)等。
其中,本申请实施例中的终端可以是任何配置有物理层和媒体接入控制层的设备或装置,终端设备也可称为接入终端。例如,用户设备(User Equipment,UE)、用户单元、用户站、移动站、移动台、远方站、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、个人数字线性处理(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线性处理设备、车载设备、可穿戴设备等等。本申请实施例以车载终端为例进行说明,但并不限于此。
可选地,在本申请的一些实施例中,本申请实施例可以适用于同时存在多种传输模式的场景。例如,第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)Rel-14中定义的传输模式3和传输模式4,以及Rel-14中定义的传输模式。
应理解,上述传输模式3在NR-V2X中还可以称为模式1,上述传输模式4在NR-V2X中还可以称为模式2,本申请实施例对此不做具体限定。
为便于对本申请实施例的理解,下面对上述几种模式进行简单说明。
图1是本申请实施例的模式3的示意图。图2是本申请实施例的模式4的示意图。
在图1所示的传输模式3中,车载终端(车载终端121和车载终端122)的传输资源是由基站110分配的,车载终端根据基站110分配的资源在侧行链路上进行数据的发送。具体地,基站110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。
在图2所示的传输模式4中,车载终端(车载终端131和车载终端132)采用侦听(sensing)加预留(reservation)的传输方式,车载终端在侧行链路的资源上自主选取传输资源进行数据传输。
下面以车载终端131为例进行具体说明。
车载终端131在资源池中通过侦听的方式获取可用的传输资源集合,车载终端131从该集合中随机选取一个资源进行数据的传输。
由于车联网系统中的业务具有周期性特征,本申请实施例中,车载终端131还可以采用半静态传输的方式。即车载终端131取一个传输资源后,在多个传输周期中持续的使用该资源,以降低资源重选以及资源冲突的概率。
进一步地,车载终端131可以在本次传输的控制信息中携带预留下次传输资源的信息,使得其他终端(例如,车载终端132)可以通过检测该用户的控制信息判断这块资源是否被该用户预留和使用,达到降低资源冲突的目 的。
在Rel-16中引入的模式指可以由一个UE控制另一个UE的侧行链路发送和/或接收。例如,结合图2来说,可以由车载终端131控制车载终端132的侧行链路发送和/或接收。又例如,可以由车载终端132控制车载终端131的侧行链路发送和/或接收
图3是本申请实施例的的场景的示意性框图。
如图3所示,第一终端设备220可以同时和网络设备210和第二终端设备230建立连接。
所述第一终端设备220可以同时处于多种模式下。例如,所述第一终端设备220可以通过所述网络设备210处于如图1所示的传输模式3,所述第一终端设备220还可以通过所述第二终端设备300处于如图2所示的传输模式4,所述第一终端设备220还可以处于Rel-16中引入的模式。
这种情况下,现有的数据传输方案并不能满足数据传输需求。例如,目前并没有所述第一终端设备220同时处于多种模式下时,如何进行数据发送和接收的技术方案。
本申请实施例的技术方案,能够使得所述第一终端设备220有效接收和/或发送侧行链路数据。
应理解,上述实施例中的传输模式3和传输模式4以及在Rel-16中引入的模式仅为本申请实施例的示例,本申请实施例并不限于此。例如,在其他可替代实施例中,也可以定义新的传输模式。
图4是本申请实施例的无线通信方法300的示意性流程图。该方法30可以由终端设备执行。例如,图4中所示的第一终端设备可以是如图3所示的终端设备。
如图4所示,所述方法300可以包括:
S310,第一终端设备在至少两种模式下发送和/或接收侧行链路数据。
具体地,所述第一终端设备可以不同的侧行链路数据确定不同的模式,进而基于不同的模式发送和/或接收对应的侧行链路数据,进而能够有效提高数据传输的效率。
其中,所述至少两种模式包括以下模式中的至少两项;
所述第一终端设备的侧行链路数据的发送和/或接收由网络设备配置和/或调度;所述第一终端设备的侧行链路数据的发送和/或接收由第一终端设备 配置和/或调度;所述第一终端设备的侧行链路数据的发送和/或接收由第二终端设备配置和/或调度。
例如,所述至少两种模式可以包括上述实施例中的传输模式3和传输模式4以及在Rel-16中引入的模式。
下面对所述第一终端设备为不同的数据确定不同的模式的实现方式进行详细说明。
可选地,在本申请的一些实施例中,所述至少两种模式可以分别用于发送和/或接收不同情况下的侧行链路数据。
换句话说,不同的传输模式对应不同情况的侧行链路数据。
其中,所述不同情况下的侧行链路数据包括:
传播方式、目标地址、源地址、提供者服务标识(Provider service identification,PSID)、智能交通系统-应用标识(Intelligent transportation systems application identification,ITS-AID)、接入方式、承载、逻辑信道、信道条件、速度、同步类型以及载波中任一项的不同情况下的侧行链路数据。
例如,所述至少两种模式分别用于发送和/或接收传播方式的不同情况下的侧行链路数据。
换句话说,所述至少两种模式分别用于发送和/或接收不同传播方式下的侧行链路数据。
具体地,所述传播方式的不同情况可以包括单播传播方式、组播传播方式和广播传播方式。假设所述至少两种模式可以包括第一模式、第二模式以及第三模式,则上述三种模式可以分别用于传输上述三种广播模式下的侧行链路数据。例如,所述第一模式用于传输单播传播方式下的侧行链路数据,所述第二模式用于传输组播传播方式下的侧行链路数据,所述第三模式用于传输广播传播方式下的侧行链路数据。
又例如,所述至少两种模式分别用于发送和/或接收接入方式的不同情况下的侧行链路数据。
换句话说,所述至少两种模式分别用于发送和/或接收不同接入方式下的侧行链路数据。
具体地,所述接入方式可以包括第一接入方式和第二接入方式。例如所述第一接入方式为通过长期演进(Long Term Evolution,LTE)接入网络的方式传输数据,所述第二接入方式为通过新空口(New Radio,NR)接入网 络的方式传输数据。假设所述至少两种模式可以包括第一模式、第二模式以及第三模式,则上述三种模式可以分别用于传输上述两种接入方式下的侧行链路数据。例如,所述第一模式和第二模式用于传输第一接入方式下的侧行链路数据,所述第三模式用于传输第二接入方式下的侧行链路数据。
应理解,上述实施例为基于一个因素将所述第一终端设备的侧行链路数据划分为不同情况下的侧行链路数据,不应理解为对本申请实施例的具体限定。
例如,在其他替代实施例中,可以基于多个因素将所述第一终端设备的侧行链路数据划分为不同情况下的侧行链路数据。
换句话说,所述至少两种模式可以是用于发送和/或接收不同情况下的侧行链路数据,其中所述不同情况下的侧行链路数据可以包括传播方式、目标地址、源地址、PSID、ITS-AID、接入方式、承载、逻辑信道、信道条件、速度、同步类型以及载波中的多项在不同情况下的侧行链路数据。
例如,所述至少两种模式分别用于发送和/或接收传播方式不同且接入方式不同的侧行链路数据。
具体地,所述传播方式的不同情况可以包括单播传播方式、组播传播方式和广播传播方式。所述接入方式可以包括第一接入方式和第二接入方式。假设所述至少两种模式可以包括第一模式、第二模式以及第三模式,则所述第一模式用于传输第一接入方式下的且通过单播传播方式传输的侧行链路数据,所述第二模式用于传输第一接入方式下的且通过组播传播方式或广播传播方式传输的侧行链路数据,所述第三模式用于传输第二接入方式下的通过任意一种传播方式传输的侧行链路数据。
应理解,上述PSID和ITS-AID仅为应用标识的一种示例,不应理解为对本申请实施例的限制。例如,在其他可替代实施例中,还可以采用其他标识对所述第一终端设备的侧行链路数据进行划分,使得所述至少两种模式用于传输不同标识下的侧行链路数据。
还应理解,本申请实施例对传播方式、目标地址、源地址、PSID、ITS-AID、接入方式、承载、逻辑信道、信道条件、速度、同步类型以及载波的不同情况不做具体限定。
例如,所述传播方式的不同情况可以现有的不同传播方式,也可以是新定义的传播方式。
又例如,所述同步类型的不同情况可以是同步对象不同的情况,也可以是同步方式的不同情况。例如,所述同步类型的不同情况可以包括不同的同步网络类型。
需要注意的是,本申请实施例的第一终端设备可以在至少两个模式下发送和/或接收侧行链路数据,但由于所述第一终端设备的能力等因素的限制,所述终端设备在发送和/或接收侧行链路数据之前,需要事先确定侧行链路数据的发送顺序或接收顺序。
下面对所述第一终端设备在所述至少两种模式下发送和/或接收侧行链路数据的具体实现方式进行详细说明。
实施例一:
本申请实施例中,所述第一终端设备可以根据优先级信息在所述至少两种模式下发送和/或接收侧行链路数据。
可选地,所述第一终端设备在发送和/或接收侧行链路数据之前,可以根据所述至少两种模式确定所述优先级信息。
例如,所述第一终端设备在发送和/或接收侧行链路数据之前,可以根据所述至少两种模式中每种模式对应的优先级确定所述优先级信息。具体地,所述至少两种模式中的每种模式可以对应一个优先级,进而所述第一终端设备可以根据所述至少两种模式中每种模式对应的优先级,发送和/或接收对应模式下的侧行链路数据。
换句话说,所述优先级信息可以包括所述至少两种模式中每种模式对应的优先级信息。
可选地,所述第一终端设备在发送和/或接收侧行链路数据之前,可以根据所述侧行链路数据确定所述优先级信息。
例如,所述第一终端设备在发送和/或接收侧行链路数据之前,可以根据所述侧行链路数据的服务质量(Quality of service,QoS)对应的优先级确定所述优先级信息。具体地,所述第一终端设备可以根据所述侧行链路数据的QoS对应的优先级确定所述侧行链路数据的发送和/或接收顺序,然后基于所述发送和/或接收顺序采用相应的模式,发送和/或接收对应模式下的侧行链路数据。
应理解,本申请实施例对所述第一终端设备获取所述优先级信息的具体方式不做额外限定。例如,所述优先级信息可以是多个终端设备协商确定的, 也可以是协议规定的。例如,所述第一终端设备可以预配置有所述优先级信息。
还应理解,本申请对所述每种模式对应的优先级的具体等级和数值不做限定。例如,在一些实施例中,所述至少两种模式中不同的模式对应不同的优先级。又例如,在另一些实施例中,所述至少两种模式中不同的模式可以对应同一优先级。类似地,本申请对所述每种QoS属性对应的优先级的具体等级和数值不做限定。例如,在一些实施例中,所述不同的QoS属性对应不同的优先级。又例如,在另一些实施例中,所述不同的QoS属性可以对应同一优先级。

换句话说,所述第一终端设备可以优先发送和/或接收特定通信模式和/或特定传播方式和/或特定目标地址和/或特定源地址和/或特定PSID和/或特定ITS-AID和/或特定接入方式和/或特定承载和/或特定逻辑信道和/或特定信道条件和/或特定速度和/或特定同步类型和/或特定载波下的侧行链路数据。
例如,所述第一终端设备可以优先发送和/或接收特定传播方式下的侧行链路数据。具体地,所述第一终端设备可以优先发送和/或接收广播传播方式和/或组播传播方式下的侧行链路数据。
可选地,所述第一终端设备在特定时频域资源中,优先发送和/或接收满足第一要求的侧行链路数据。
换句话说,所述第一要求是针对所述特定时频域资源设置的。即所述第一终端设备只有在所述特定时频域资源上发送和/或接收侧行链路数据时,优先发送和/或接收满足第一要求的侧行链路数据;而所述第一终端设备在所述特定时频域资源在外的资源上发送和/或接收侧行链路数据时,可以不优先发送和/或接收满足第一要求的侧行链路数据。
其中,所述特定时频域资源为网络配置的资源,也为预配置资源,本申 请实施例对此不做具体限定。
需要注意的是,本申请实施例中的所述第一终端设备可以优先发送和/或接收特定通信模式下的侧行链路数据。例如,所述第一终端设备可以优先发送和/或接收所述至少两种模式中第一模式下的侧行链路数据。换句话说,所述特定时频域资源为所述至少两种模式中的多种模式的共用资源,进一步地,所述第一模式的优先级最高。但本申请实施例并不限于此。例如,所述特定时频域资源也可以为所述至少两种模式中的第一模式的专属资源。
换句话说,所述第一终端设备在所述特定时频域资源上发送和/或接收侧行链路数据时,只能采用所述至少两种模式中的第一模式发送和/或接收侧行链路数据。
具体地,所述第一终端设备可以在所述特定时频域资源上,采用所述第一模式,优先发送满足第二要求的侧行链路数据。其中,所述第二要求可以包括以下中的至少一项的特定情况:
传播方式、目标地址、源地址、PSID、ITS-AID、接入方式、承载、逻辑信道、信道条件、速度、同步类型以及载波。
换句话说,所述第一终端设备可以在所述特定时频域资源中,优先发送和/或接收特定传播方式和/或特定目标地址和/或特定源地址和/或特定PSID和/或特定ITS-AID和/或特定接入方式和/或特定承载和/或特定逻辑信道和/或特定信道条件和/或特定速度和/或特定同步类型和/或特定载波下的侧行链路数据。
应理解,本申请实施例对所述第一模式的具体类型不做额外限定。例如,所述第一模式可以是上述实施例所述的传输模式3和传输模式4以及在Rel-16中引入的模式中的任一模式。
还应理解,上述实施例一和实施例二可以结合使用。
即,所述第一终端设备可以根据优先权信息,优先发送和/或接收满足第一要求的侧行链路数据。
例如,所述第一终端设备可以根据所述至少两个模式中每个模式对应的优先级,优先发送和/或接收特定通信模式和/或特定传播方式和/或特定目标地址和/或特定源地址和/或特定PSID和/或特定ITS-AID和/或特定接入方式和/或特定承载和/或特定逻辑信道和/或特定信道条件和/或特定速度和/或特定同步类型和/或特定载波下的侧行链路数据。
又例如,所述第一终端设备可以根据所述所述侧行链路数据的QoS对应的优先级,优先发送和/或接收特定通信模式和/或特定传播方式和/或特定目标地址和/或特定源地址和/或特定PSID和/或特定ITS-AID和/或特定接入方式和/或特定承载和/或特定逻辑信道和/或特定信道条件和/或特定速度和/或特定同步类型和/或特定载波下的侧行链路数据。
进一步地,所述第一终端设备可以在特定时频域资源内,根据所述优先权信息,优先发送和/或接收满足第一要求的侧行链路数据。
需要注意的是,由于所述至少两种模式用于传输的侧行链路数据也可以是根据传播方式、目标地址、源地址、PSID、ITS-AID、接入方式、承载、逻辑信道、信道条件、速度、同步类型以及载波中的至少一项进行区分的,因此,可以使得用于划分所述侧行链路数据的因素与所述第一要求中包括的因素完全不同,以避免实施例一和实施例二结合过程中出现冲突。
进一步地,即使实施例一和实施例二的技术方案在结合过程中出现冲突时,所述第一终端设备可以优先采用实施例一所述的技术方案或实施例二所述的技术方案。
例如,假设实施例一中,所述至少两个模式中的第一模式优先级最高,实施例二中的第一要求包括特定的第二模式,则所述第一终端设备可以优先发送和/或接收第一模式下的侧行链路数据,也可以优先发送和/或接收第二模式下的侧行链路数据。
