Description

控制信道发送、接收方法、装置及存储介质 技术领域
本公开涉及通信技术领域,尤其涉及一种控制信道发送、接收方法、装置及存储介质。
背景技术
随着通信技术的发展,车用无线通信技术(Vehicle to Everything,V2X)被广泛应用。V2X技术是将车辆与一切事物相连接的新一代信息通信技术,其中V代表车辆,X代表任何与车交互信息的对象。
蜂窝车用无线通信技术(Cellular-Vehicle to Everything,C-V2X)是基于4G/5G等蜂窝网通信技术演进形成的车用无线通信技术,包含两种通信接口:一种是车、人、路之间的短距离直接通信接口(PC5),另一种是蜂窝通信接口(Uu),可实现长距离和更大范围的可靠通信。为提升C-V2X的传输性能,一方面,在PC5接口上,物理层结构进行增强以支持更高的速度,支持全球卫星导航系统同步和更加高效的资源分配机制以及拥塞控制机制等。另一方面,在Uu接口上,包括对上下行传输进行增强,以及考虑多接入边缘计算能力等。
相关技术中,C-V2X除了支持广播方式传送以外,还支持单播和组播的传输方式,即针对一个或者几个目标用户进行发送。因此,在不同的传输场景下物理侧行链路控制信道(Physical Sidelink Control Channel,PSCCH)传输的数据大小会存在较大的差异。为了避免用户过多的盲检,以及降低用户感知的复杂度,当前提出了一种2-stage PSCCH传输方式,即PSCCH的传输分为两部分。在第一部分PSCCH传输所有用户都需要接收的数据,在第二部分PSCCH传输一些特定用户需要接收的数据(如目标用户标识,用户的混合自动重传请求(Hybrid Automatic Repeat reQuest,HARQ)相关的内容等)。然而,目前的C-V2X中2-stage PSCCH的传输性能仍较低。

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。
本公开实施例提供的控制信道发送、接收方法可应用于两个设备之间直接通信的通信场景,例如车辆到其他节点(V2X)的车用无线通信场景等。其中,V代表车辆,X代表任何与车辆交互的对象。当前X主要包含车、人、交通路侧基础设施和网络。V2X交互的信息模式包括:车与车之间(Vehicle to Vehicle,V2V)、车与路之间(Vehicle to Infrastructure,V2I)、车与人之间(Vehicle to Pedestrian,V2P)、车与网络之间(Vehicle to Network,V2N)的交互。本公开中,两个设备之间直接通信的通信场景也可以是终端到终端(Device to Device,D2D)的通信场景。本公开实施例中进行直接通信的设备可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备,以及各种形式的用户设备(User Equipment,UE),移动台(Mobile station,MS),终端(terminal),终端设备(Terminal Equipment)等等。为方便描述,本公开实施例以下将进行直接通信的设备称为终端。
图1所示为终端间直接进行通信的场景示意图,网络设备为终端1配置各种用于数据传输的传输参数,终端1作为数据发送方,与终端2和终端3进行终端与终端之间的通信。本公开实施例中网络设备是一种部署在无线接入网中并为终端提供无线通信功能的装置, 可以是基站(base station,BS),例如可以是包括各种形式的宏基站,微基站,中继站,接入点等等。在采用不同的无线接入技术的系统中,具备基站功能的设备的名称可能会有所不同,例如在长期演进(Long Term Evolution,LTE)网络中,称为演进的节点B(evolved NodeB,eNB或者eNodeB),在新无线网络(New Radio,NR)中,称为gNB等等。
网络设备与终端之间进行通信的链路为上下行链路,终端与终端之间的链路是侧行链路。一些配置中,终端与终端之间的链路可对应于一个或多个侧行链路(sidelink)信道,诸如物理侧行链路广播信道(PSBCH)、物理侧行链路发现信道(PSDCH)、物理侧行链路共享信道(PSSCH)、和/或物理侧行链路控制信道(PSCCH)。其中,PSCCH用于传输侧行链路控制信息(Sidelink Control information,SCI)。
相关技术中,提出一种采用2-stage PSCCH传输方式进行PSCCH的传输,该传输可以是发送和/或接收,即PSCCH的发送和/或接收分为两部分。例如,在第一部分PSCCH传输所有终端都需要接收的数据,在第二部分PSCCH传输一些特定终端需要接收的数据。本公开以下将第一部分PSCCH称为第一PSCCH,将第二部分PSCCH称为第二PSCCH。目前,采用2-stage PSCCH传输方式进行PSCCH传输的传输性能相对1-stage PSCCH的传输性能较差。
有鉴于此,本公开提供一种控制信道传输方法,在该控制信道传输方法中,第一PSCCH和第二PSCCH采用不同的传输资源进行传输。然而第一PSCCH传输的数据由于涉及到需要接收数据的终端较多,并且感知检测性能很大,故本公开提供一种控制信道传输方法,以提高第一PSCCH的传输性能,进而提高2-stage PSCCH传输方式下的PSCCH的传输性能。
图2是根据一示例性实施例示出的一种控制信道发送方法的流程图,如图2所示,该控制信道发送方法用于终端中,包括以下步骤S11和步骤S12。
在步骤S11中,确定第一信息。
本公开中,将用于承载第一PSCCH的传输资源称为第一传输资源。本公开中通过为该第一传输资源设置固定资源位置,以提高第一PSCCH的传输性能。
本公开中,第一传输资源的固定资源位置可通过第一信息表征。第一信息可通过系统消息或无线资源控制(Radio Resource Control,RRC)信令确定。其中,一方面本公开中可通过系统消息预先配置第一传输资源的固定资源位置。在通过系统消息预先配置第一传输资源的固定资源位置之际,该第一信息可以是系统消息。另一方面,本公开中也可通过RRC信令通知第一传输资源的固定资源位置。在通过RRC信令通知第一传输资源的固定 资源位置之际,该第一信息也可以是RRC信令。
在步骤S12中,利用具有固定资源位置的第一传输资源发送第一PSCCH。
本公开中确定了第一传输资源的固定资源位置,则可依据该固定资源位置,进行第一PSCCH的传输。
本公开中通过为第一传输资源设置固定资源位置,可以使得接收第一PSCCH的终端在盲检的时候,依据该固定资源位置,盲检第一PSCCH,提高传输性能。
本公开以下对上述控制信道发送方法的实施过程进行说明。
本公开一示例中,第一传输资源的固定资源位置可以是第一传输资源的指定传输位置。通过该指定传输位置对应的第一传输资源承载第一PSCCH,可使得后续接收第一PSCCH的终端在盲检时,通过该指定传输位置确定可能的起始位置,并在该可能的起始位置下盲检第一PSCCH,提高第一PSCCH的传输性能。
本公开另一示例中,第一传输资源的固定资源位置也可以是第一传输资源的指定起始位置。通过该指定起始位置对应的第一传输资源承载第一PSCCH,可使得后续接收第一PSCCH的终端在盲检时,通过在该指定的起始位置下盲检第一PSCCH,提高第一PSCCH的传输性能。
本公开又一示例中,为第一传输资源设定指定的聚合等级(Aggregation Level,AL)组合,例如设定AL值为2或4。本公开中通过为第一传输资源设定指定AL组合,可以使得第一传输资源具有固定大小资源,进而进一步提高传输性能。并且使接收第一PSCCH的终端,在盲检第一PSCCH之际,可以盲检对应聚合等级的第一PSCCH,提高传输性能。本公开中为描述方便将未第一传输资源设定的指定AL组合称为第一AL组合。
进一步的,在具有固定大小资源的第一传输资源中,本公开中可使第一PSCCH传输固定大小的信息比特,及第一PSCCH具有指定信息比特大小。更进一步的,具有指定信息比特大小的第一PSCCH可用于传输固定的信息比特,即具有指定信息比特大小的信息比特代表的信息为指定信息。具有指定信息比特大小的第一PSCCH传输固定的信息比特,可以使该PSCCH占用更多的物理资源或者使用更高的AL等级,进一步提高第一PSCCH的传输性能。
本公开在保证第一PSCCH的传输性能基础上,可进行第二PSCCH的发送。其中,在进行第二PSCCH传输时可利用动态可调整的动态传输资源承载第二PSCCH,进而使得采用2-stage PSCCH传输方式进行第一PSCCH和第二PSCCH传输的传输性能与采用1-stage PSCCH传输方式进行PSCCH传输的传输性能相当。为描述方便将用于承载第二 PSCCH的传输资源称为第二传输资源。
图3是根据一示例性实施例示出的另一种控制信道发送方法的流程图,如图3所示,该控制信道发送方法用于终端中,除包括步骤S11和步骤S12之外,还包括步骤S13和步骤S14。
在步骤S13中,确定第二信息。
本公开中,第二信息用于表征承载第二PSCCH的第二传输资源。
本公开中第二信息通过第一PSCCH、高层信令或系统消息确定。其中,第二传输资源可以由第一PSCCH通知。在第二传输资源由第一PSCCH通知之际,第二信息可以通过第一PSCCH确定。本公开中第二传输资源也可以是由高层信令通知,例如RRC信令通知。在第二传输资源由RRC信令通知之际,第二信息可以是RRC信令。本公开中第二传输资源也可以是系统预先配置的。在第二传输资源由系统预先配置之际,该第二信息可以是系统消息。本公开中第二传输资源也可以由终端盲检确定。
进一步的,本公开中第二信息也可用于表征第二传输资源的AL组合,以及传输的信息比特大小等中的一项或多项。本公开中,第二传输资源的AL组合称为第二AL组合。其中,第二AL组合大于第一AL组合。例如第一AL组合为2或4,第二AL组合可以为1、2、4、8等。
在步骤S14中,利用第二传输资源发送第二PSCCH。
本公开上述涉及的控制信道发送方法,第一PSCCH和第二PSCCH采用不同的传输资源进行发送,并且第一PSCCH采用具有固定资源位置的第一传输资源进行发送,第二PSCCH采用动态可调整的第二传输资源进行发送,在保证第一PSCCH的传输性能的基础上,实现第一PSCCH和第二PSCCH整体发送的传输性能。
图4是根据一示例性实施例示出的一种控制信道接收方法的流程图,如图4所示,该控制信道接收方法用于终端中,包括以下步骤S21和步骤S22。
在步骤S21中,确定接收第一PSCCH。
其中,第一PSCCH依据第一信息表征的第一传输资源的固定资源位置发送。
在步骤S22中,依据固定资源位置,盲检第一PSCCH。
本公开中接收第一PSCCH的终端,在确定需要接收第一PSCCH之际,可依据固定资源位置确定盲检起始位置,并在该盲检起始位置下盲检第一PSCCH。其中,盲检第一PSCCH所依据的固定资源位置可以是通过系统消息确定,也可以是由RRC信令通知。换言之第一信息可以是系统消息,也可以是RRC信令。
进一步的,本公开中盲检第一PSCCH所依据的固定资源位置可以是第一传输资源的指定传输位置,和/或第一传输资源的指定起始位置。在盲检第一PSCCH所依据的固定资源位置是第一传输资源的指定传输位置之际,则可通过指定传输位置确定该盲检起始位置。在盲检第一PSCCH所依据的固定资源位置是指定起始位置之际,则可确定盲检起始位置即为该指定起始位置。
本公开中第一传输资源具有指定的第一AL组合。
图5是根据一示例性实施例示出的另一种控制信道接收方法实施流程图。如图5所示,在第一传输资源具有指定的第一AL组合之际,依据所述固定资源位置,盲检所述第一PSCCH可采用的步骤S221和步骤S222确定。
在步骤S221中,确定盲检起始位置。
其中,本公开中盲检起始位置通过指定传输位置确定,或者该盲检起始位置为指定起始位置。
在步骤S222中,盲检上述盲检起始位置下AL值为第一AL组合中各AL的第一PSCCH。
本公开中,在终端接收第一PSCCH之际,可在通过指定传输位置确定的起始位置下盲检AL为第一AL组合中各AL组合方式的第一PSCCH,例如在指定起始位置下盲检AL为2或4的第一PSCCH。在终端接收第一PSCCH之际,也可在指定起始位置下盲检AL为第一AL组合中各AL组合方式的第一PSCCH,例如在指定起始位置下盲检AL为2或4的第一PSCCH。
更进一步的,本公开实施例中,终端还可盲检利用第二传输资源发送的第二PSCCH。
图6是根据一示例性实施例示出的又一种控制信道接收方法实施流程图。如图6所示,本公开涉及的控制信道接收方法除包括步骤S21和步骤S22之外,还可包括步骤S23。
在步骤S23中,盲检利用第二传输资源发送的第二PSCCH。
本公开中第二传输资源可由第二信息表征。
其中,本公开中第二传输资源可以由第一PSCCH通知。在第二传输资源由第一PSCCH通知之际,第二信息可以通过第一PSCCH确定。本公开中第二传输资源也可以是由高层信令通知,例如RRC信令通知。在第二传输资源由RRC信令通知之际,第二信息可以是RRC信令。本公开中第二传输资源也可以是系统预先配置的。在第二传输资源由系统预先配置之际,该第二信息可以是系统消息。本公开中第二传输资源也可以由终端盲检确定。
本公开中,第二信息还用于表征第二传输资源的第二AL组合。其中,第二AL组合大于第一传输资源的第一AL组合。
进一步的,在第二信息用于表征第二传输资源的第二AL组合之际,可通过盲检AL为第二AL组合的第二PSCCH,进行第二传输资源发送的第二PSCCH的盲检。
本公开上述提供的控制信道接收方法,终端在盲检第一PSCCH时依据第一传输资源的固定资源位置进行盲检,可以相对准确的确定盲检起始位置,进而提高感知检测性能。并且进行第一PSCCH和第二PSCCH的联合检测,可使两部分PSCCH的联合检测性能与采用1-stage方式传输的检测性能相当。
本公开以下对发送PSCCH与接收PSCCH的交互过程进行说明。其中,将发送PSCCH的终端称为终端1。接收PSCCH的终端称为终端2。
