考虑到基于现有的蜂窝通信技术支持车联网通信,可以有效利用现有基站部署,减少设备开销,也更有利于提供具有服务质量(QoS,Quality of Service)保证的服务,满足车联网业务的需求,因此,在LTE Rel-14/15中提供了蜂窝网络对于V2x通信的支持,即基于蜂窝网络的车联网通信(C-V2x,cellular based V2x)。在C-V2x中,车载设备和其他设备之间的通信可以通过基站以及核心网进行中转,即利用原有蜂窝网络中用户设备设备和基站之间的通信链路进行通信;也可以直接通过设备之间的直连链路(SL,sidelink)进行通信。与蜂窝通信相比,sidelink通信具有时延短,开销小等特点,非常适合用于车载设备和地理位置接近的其他周边设备直接的通信。LTE中的V2x sidelink通信只能支持一些基础的安全方面的V2x应用,如交换协同感知消息(CAM,Cooperative Awareness Messages)或分布式环境通知消息(DENM,Decentralized Environmental Notification Message)等信息、语言广播等。而随着自动驾驶等技术的发展,为了支持新的V2x业务,对于V2x技术的性能又提出了新的要求;利用5G新无线(NR,New Radio)技术支持新的V2x通信服务和场景已经被第三代移动通信伙伴(3GPP)计划为Rel16的一项重要内容,并且新增了V2x通信需要满足的新的业务需求,包括车队管理(Vehicles Platooning)、感知扩展(Extended Sensors)、先进驾驶(Advanced Driving)、和远程驾驶(remote driving);总体来说,NR V2x sidelink需要提供更高的通信速率,更短的通信延时,更可靠的通信质量。
相关技术中,在LTE V2x通信技术中,用户设备sidelink通信时的子载波间隔固定为15KHz,子帧长度固定为1ms。

具体实施方式
这里将详细地对示例性实施例进行说明,其示例表示在附图中。下面的描述涉及附图时,除非另有表示,不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反,它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
相关技术中,LTE V2x sidelink通信的子载波间隔固定为15KHz,子帧长度固定为1ms;使得LTE V2x sidelink通信可以仅支持一些基础的安全方面的V2x应用,如交换协同感知消息(CAM,Cooperative Awareness Messages)或分布式环境通知消息(DENM,Decentralized Environmental Notification Message)等信息、语言广播等。
同时,NR V2x sidelink通信需要支持诸如车队管理(Vehicles Platooning)、感知扩 展(Extended Sensors)、先进驾驶(Advanced Driving)和远程驾驶(remote driving)等V2x业务,而不同的V2x业务对于通信速率、通信延时、通信质量及通信距离等的需求也不相同,这就要求NR V2x sidelink技术既能够对抗高速移动下的多普勒效应、对抗高频下的载波频偏及获取较低的延时,也能够保证低速行驶中的性能、获得更大的传输距离。然而,相关技术中,由于LTE V2x sidelink通信采用固定的子载波间隔及子帧长度,无法保证NR V2xsidelink通信业务的差异化QoS要求,用户体验较差。
为了解决上述问题,本发明实施例提供了一种参数集获取方法,应用于基于直连链路通信的用户设备,方法包括:获取与待传输信息对应的目标参数集;待传输信息至少包括以下任一种信息类型或组合:同步信号、直连链路广播信息、物理层控制信息、或用户数据;使用目标参数集,传输待传输信息。本发明实施例提供的参数集获取方法,通过在NR V2x直连链路通信中支持多种参数集配置,为不同的V2x直连链路通信提供差异化的参数集,能够保证NR V2x sidelink通信业务的差异化QoS要求,提高用户体验。
基于上述分析,提出以下各具体实施例。
图1是根据一示例性实施例示出的一种参数集获取方法的流程图;该方法可以应用于直连链路通信的用户设备;如图1所示,该方法包括以下步骤101-102:
在步骤101中,获取与待传输信息对应的目标参数集;待传输信息至少包括以下任一种信息类型或组合:同步信号、直连链路广播信息、物理层控制信息、或用户数据。
示例的,该方法的执行主体可以为用户设备(UE),例如直连链路通信中的车载设备、路边设备或用户手持设备等设备。
示例的,参数集可以包括:子载波间隔以及相应的时域调制符号长度、循环前缀(CP,cyclic Prefix)长度及时间单元(slot)长度等一系列参数的取值。与待传输信息对应的目标参数集可以为用以发送待传输信息的发送参数集、和/或用以接收待传输信息的接收参数集。
示例的,本公开在NR V2x直连链路通信中支持多种参数集配置;获取与待传输信息对应的目标参数集的实现方式至少可以包括以下任意一种方式或组合:
实现方式1、由用户设备预先从基站或服务器获取在V2x直连链路通信时用户设备使用的多种参数集配置,例如:
方式a)对于NR V2x直连链路通信,用户设备可以通过接收基站发送的配置消息半静态的获得可以使用的发送参数集和/或接收参数集;例如在基站发送的配置消息中包括用户设备用以传输待传输信息的目标参数集,用户设备通过解析配置消息得到与待传输信息对应的目标参数集。
方式b)对于NR V2x直连链路通信,用户设备可以通过接收基站发送的下行控制消息动态的获得用以传输待传输信息的目标参数集;例如在基站发送的下行控制消息中包括用户设备用以传输待传输信息的目标参数集,用户设备通过解析下行控制消息,得到与待传输信息对应的目标参数集。
示例的,基站发送的下行控制消息中包括用户设备下一次传输物理层控制信息和/或用户数据所使用的参数集;用户设备解析下行控制消息,得到用以传输物理层控制信息和/或用户数据的参数集。需要说明的是,当用户设备从基站获得的参数集和预配置的参数集发生冲突时,用户设备可以使用从基站获得的参数集传输待传输信息。
实现方式2、可以在用户设备中预配置在V2x直连链路通信时用户设备使用的多种参数集配置,例如:
方式1)针对用户设备接收/发送通信信息时所使用的不同的载波频带,可以预先为不同的载波频带配置不同的参数集,建立载波频带与参数集的对应关系。用户设备获取传输待传输信息所使用的目标载波频带,根据预设的载波频带与参数集的对应关系获取与目标载波频带对应的目标参数集。例如,预先为用户设备配置如下信息:当载波频率为f1时,参数集配置为:{30KHz子载波间隔,SC-FDMA调制,普通长度的循环前缀,时间单元长度为0.5ms};而当载波频率为f2时,参数集配置为:{60KHz子载波间隔,OFDM调制,扩展的循环前缀,时间单元长度为0.25ms}。
方式2)针对待传输信息的不同信息类型,可以预先为不同的信息类型配置不同的参数集,建立信息类型与参数集的对应关系。用户设备根据预设的待传输信息与参数集的对应关系,获取与待传输信息对应的目标参数集。待传输信息至少包括以下任一种信息类型或组合:同步信号、直连链路广播信息、物理层控制信息、或用户数据。对于同步信号、直连链路广播信息、物理层控制消息及用户数据,可以分别为用户设备配置不同的发送/接收参数集;例如,传输同步信号所使用的参数集配置为:{15KHz子载波间隔,SC-FDMA调制,普通长度的循环前缀,时间单元长度为1ms};传输物理层控制信息所使用的参数集配置为:{30KHz子载波间隔,SC-FDMA调制,普通长度的循环前缀,时间单元长度为0.5ms};传输用户数据所使用的参数集配置为:{60KHz子载波间隔,FDM调制,普通长度的循环前缀,时间单元长度为0.25ms}。
方式3)针对同一信息类型的待传输信息,也可以预先为不同的时间频率资源集合配置不同的参数集,建立时间频率资源集合与参数集的对应关系。用户设备获取传输待传输信息所使用的时间频率资源集合,根据预设的时间频率资源集合与参数集的对应关系获取与时间频率资源集合对应的目标参数集。
实现方式3、由用户设备从对端设备处获取在V2x直连链路通信时用户设备使用的多种参数集配置,例如:
对于NR V2x直连链路通信,与用户设备进行V2x直连链路通信的对端设备发送的同步信号/直连链路广播信息中可以包含对端设备传输物理层控制信息和/或用户数据所使用的参数集的信息;用户设备可以通过接收对端设备发送的同步信号/直连链路广播信息,根据对端设备发送的同步信号或直连链路广播信息,确定对端设备用以传输物理层控制信息和/或用户数据的参数集,即获知对端设备传输物理层控制信息和/或用户数据所使用的参数集,并将对端设备用以传输物理层控制信息和/或用户数据的参数集,确定为用户设备用以传输待传输信息 的目标参数集;利用目标参数集传输待传输信息;其中,待传输信息例如物理层控制信息、和/或用户数据等。例如,用户设备使用目标参数集接收对端设备发送的物理层控制信息和/或用户数据,和/或,用户设备使用目标参数集向对端设备发送物理层控制信息和/或用户数据;再例如,用户设备使用目标参数集接收除对端设备之外的其他设备发送的物理层控制信息和/或用户数据,和/或,用户设备使用目标参数集向除对端设备之外的其他设备发送物理层控制信息和/或用户数据。
示例的,用户设备根据对端设备发送的同步信号或直连链路广播信息,确定对端设备用以传输物理层控制信息和/或用户数据的参数集的具体实现方式可以包括以下任意一种方式:
方式A、用户设备检测对端设备发送同步信号或直连链路广播信息时所使用的参数集;根据对端设备发送同步信号或直连链路广播信息时所使用的参数集,确定对端设备用以传输物理层控制信息和/或用户数据的参数集。
由于对端设备发送同步信号/或直连链路广播信息所使用的参数集决定了对端设备发送物理层控制信息和/或用户数据所使用的参数集;根据对端设备发送同步信号或直连链路广播信息时所使用的参数集,就可以确定对端设备用以传输物理层控制信息和/或用户数据的参数集。可选的,也可以预先在用户设备中配置对端设备用以传输物理层控制信息和/或用户数据的参数集信息。
方式B、对端设备传输不同的物理层控制信息和/或用户数据的参数集可以使用不同的同步信号序列,或者使用不同的广播信息参考信号序列,预先建立同步信号序列或直连链路广播信息参考序列与参数集的对应关系。用户设备根据对端设备发送的同步信号或直连链路广播信息,获取对端设备使用的同步信号序列或直连链路广播信息参考序列;根据预设的同步信号序列或直连链路广播信息参考序列与参数集的对应关系,确定对端设备用以传输物理层控制信息和/或用户数据的参数集。
方式C、在对端设备发送的同步信号或直连链路广播信息中包括第一指示信息;第一指示信息用于指示对端设备用以传输物理层控制信息和/或用户数据的参数集;用户设备解析对端设备发送的同步信号或直连链路广播信息,得到对端设备用以传输物理层控制信息和/或用户数据的参数集。
例如,使用直连链路广播信息中的特定比特位指示不同的物理层控制信息/用户数据所对应的参数集;例如在预配置中为物理层控制信息/用户数据配置了4种可能使用的参数集,在直连链路广播信息中使用2比特指示具体使用的是哪个参数集。可选的,根据预配置中配置的候选参数集的个数,确定直连链路广播信息中指示位的长度。
再例如,在直连链路广播信息中指示物理层控制信息/用户数据所能够使用的时间/频率资源集合,以及每个时间/频率集合所对应的参数集。例如在直连链路广播信息中指定频率资源范围RB 0-24为资源集合1,对应参数集1;频率资源范围25-49为资源集合2,对应参数集2。那么使用了资源集合1中的时频资源的物理层控制信息/用户数据需要使用参数集1;而如果使用资源集合2中时频资源的物理层控制信息/用户数据需要使用参数集2。
实现方式4、用户设备接收对端设备发送的同步信号或直连链路广播信息;当用户设备将对端设备发送的同步信号确定为用户设备发送信号的同步参考信号时,将对端设备发送同步信号或直连链路广播信息所使用的参数集,确定为用户设备发送同步信号或直连链路广播信息所使用的目标参数集。例如,用户设备2同时接收到用户设备1和用户设备4分别所发送的同步信号或直连链路广播信息,假设用户设备2选择了用户设备1发送的同步信号作为用户设备2发送信号的同步参考信号,那么用户设备2向除了用户设备1和用户设备4之外的用户设备3发送的同步信号或直连链路广播信息所使用的参数集应该和用户设备1发送的同步信号或直连链路广播信息使用的参数集一致。
实现方式5、用户设备接收对端设备发送的物理层控制信息;物理层控制信息中携带第二指示信息,第二指示信息用于指示传输用户数据和/或反馈信息时所使用的参数集;解析对端设备发送的物理层控制信息,得到用户设备传输用户数据和/或反馈信息时所使用的目标参数集。
示例的,直连链路通信中的物理层控制信息(sidelink control information)包括但是不限于:指示用户设备在传输用户数据所使用的时频资源、调制编码方式等参数的调度分配(SA,scheduling assignment)控制信息。物理层控制信息可以隐性的指示传输用户数据和/或反馈信息时所使用的参数集,例如通过不同的参考信号的序列选择进行指示;或者,物理层控制信息可以显性的指示传输用户数据和/或反馈信息时所使用的参数集,例如在物理层控制信息中包含2比特,当取值为“00”,“01”,“10”,“11”时,用户数据传输使用的参数集中子载波间隔分别为30KHz,60KHz,120KHz,240KHz。
可选的,第二指示信息可以用于指示对端设备发送用户数据所使用的参数集,也可以用于指示用户设备发送用户数据所使用的参数集,还可以用于指示用户设备向对端设备发送反馈信息所使用的参数集。
在步骤102中,使用目标参数集,传输待传输信息。
示例的,用户设备获取与待传输信息对应的目标参数集之后,使用目标参数集接收和/或发送待传输信息。
采用本发明实施例提供的技术方案,通过在NR V2x直连链路通信中支持多种参数集配置,使用与待传输信息对应的目标参数集传输待传输信息,实现为不同的V2x直连链路通信提供差异化的参数集,能够保证NR V2x sidelink通信业务的差异化QoS要求,如此,能够提高用户体验。
图2是根据一示例性实施例示出的一种参数集获取方法的流程图,如图2所示,在图1所示实施例的基础上,本发明涉及的参数集获取方法可以包括以下步骤201-204:
在步骤201中,接收对端设备发送的同步信号或直连链路广播信息。
在步骤202中,根据对端设备发送的同步信号或直连链路广播信息,确定对端设备用以传输物理层控制信息和/或用户数据的参数集。
在步骤203中,将对端设备用以传输物理层控制信息和/或用户数据的参数集,确定为用 户设备用以传输待传输信息的目标参数集。
在步骤204中,使用目标参数集,传输待传输信息。
示例的,待传输信息至少包括以下任一种信息类型或组合:同步信号、直连链路广播信息、物理层控制信息、或用户数据。
采用本发明实施例提供的技术方案中,由用户设备从对端设备处获取在V2x直连链路通信时用户设备用以传输待传输信息的目标参数集,实现为不同的V2x直连链路通信提供差异化的参数集,能够保证NR V2x sidelink通信业务的差异化QoS要求,提高用户体验。
图3是根据一示例性实施例示出的一种参数集获取方法的流程图,如图3所示,在图1所示实施例的基础上,本发明涉及的参数集获取方法可以包括以下步骤301-305:
在步骤301中,接收对端设备发送的同步信号或直连链路广播信息。
在步骤302中,检测对端设备发送同步信号或直连链路广播信息时所使用的参数集。
在步骤303中,根据对端设备发送同步信号或直连链路广播信息时所使用的参数集,确定对端设备用以传输物理层控制信息和/或用户数据的参数集。
在步骤304中,将对端设备用以传输物理层控制信息和/或用户数据的参数集,确定为用户设备用以传输待传输信息的目标参数集。
在步骤305中,使用目标参数集,传输待传输信息。
采用本发明实施例提供的技术方案中,由于对端设备发送同步信号/或直连链路广播信息所使用的参数集决定了对端设备发送物理层控制信息和/或用户数据所使用的参数集,从而用户设备根据对端设备发送同步信号或直连链路广播信息时所使用的参数集,就可以确定对端设备用以传输物理层控制信息和/或用户数据的参数集,进而确定用户设备用以传输待传输信息的目标参数集,从而实现为不同的V2x直连链路通信提供差异化的参数集,能够保证NR V2x sidelink通信业务的差异化QoS要求。

在步骤401中,接收对端设备发送的同步信号或直连链路广播信息。
在步骤402中,根据对端设备发送的同步信号或直连链路广播信息,获取对端设备使用的同步信号序列或直连链路广播信息参考序列。
在步骤403中,根据预设的同步信号序列或直连链路广播信息参考序列与参数集的对应关系,确定对端设备用以传输物理层控制信息和/或用户数据的参数集。
在步骤404中,将对端设备用以传输物理层控制信息和/或用户数据的参数集,确定为用户设备用以传输待传输信息的目标参数集。
在步骤405中,使用目标参数集,传输待传输信息。
采用本发明实施例提供的技术方案中,针对NR V2x sidelink通信,对端设备传输不同的物理层控制信息和/或用户数据的参数集可以使用不同的同步信号序列,或者使用不同的广播信息参考信号序列,通过预先建立同步信号序列或直连链路广播信息参考序列与参数集的 对应关系,使得用户设备可以根据预设的同步信号序列或直连链路广播信息参考序列与参数集的对应关系,确定对端设备用以传输物理层控制信息和/或用户数据的参数集,进而确定用户设备用以传输待传输信息的目标参数集,从而实现为不同的V2x直连链路通信提供差异化的参数集,能够保证NR V2x sidelink通信业务的差异化QoS要求。
