Description

一种信息传输的方法以及装置 技术领域
本申请涉及通信领域,尤其涉及一种信息传输的方法以及装置。
背景技术
全球通信技术的发展日新月异,其中无线通信技术的发展速度与应用领域已经超过了有线通信技术,呈现出如火如荼的发展态势。在智能设备所在的无线通信场景中,在一定通信区域或范围内可以包括多个通信域。该通信域是指一组具有通信关系的通信节点,以及通信节点之间的通信连接关系(即通信链路)组成的系统,一个通信域包括一个主通信节点(可以简称为主节点)和至少一个从通信节点(可以简称为从节点),其中,主节点管理通信域的时频资源,并具有为通信域中的通信节点间的通信链路调度资源的功能。
多路从节点向主节点并行传输数据时,主节点需要针对每个从节点的数据包分别发送反馈数据包,主节点向多个从节点分别发送反馈消息开销较大。
发明内容
本申请提供了一种信息传输的方法以及装置,用于减少主节点对从节点的反馈开销。
本申请第一方面提供了一种信息传输的方法,该方法包括:第一节点接收来自M个第二节点的N个第一消息,M为大于1的整数,N为大于等于M的整数;第一节点在第一资源上向M个第二节点发送第二消息,第二消息包括与N个第一消息一一对应的N个第一反馈信息。
上述第一方面中,M个第二节点给第一节点发送N个第一消息,其中,每个第二节点分别发送至少一个第一消息,第一节点在接收的N个第一消息后,可以在第一资源上发送同时包括与N个第一消息一一对应的N个第一反馈信息的第二消息,相应的,M个第二节点可以在第一资源上获取该第二消息。即,第一节点将与M个第二节点对应的反馈信息合并为一个第二消息,第一节点只需要发送一次第二消息即可对M个第二节点进行反馈,不需要对每个第二节点进行单独反馈,可以减少主节点对从节点的反馈开销。
在一种可能的实施方式中,M个第二节点包含于第一通信组。
上述可能的实施方式中,第一通信组可以是包括一定通信区域内的所有从节点,M个第二节点为所有从节点中的部分或全部,或者第一通信组可以是在一定通信区域内的所有从节点中选择M个第二节点构成的,即第一节点通过组播的方式向M个第二节点发送第二消息。
在一种可能的实施方式中,N个第一反馈信息包括L*N比特的位图,每L个比特对应一个第一反馈信息,L为大于或等于1的整数。
上述可能的实施方式中,N个第一反馈信息在第一资源上是以L*N比特的位图的排布传输的,每个第一反馈信息有固定的L个比特,N个第一反馈信息具有传输顺序,第二节点可以在相应的L比特接收第一反馈信息,提高方案的可行性。
在一种可能的实施方式中,第一消息包括数据包和数据包的标识。
上述可能的实施方式中,第二节点向第一节点发送的第一消息包括的数据包可以为空或不为空,第一消息中还包括该数据包的标识,用以与第二节点在不同周期或相近发送的消息中对不同的数据包作区别,第一节点可以根据标识确定该数据包是否为想要接收的数据包,以提高第一节点与第二节点间的传输效率。
在一种可能的实施方式中,第四反馈信息为N个第一反馈信息中的一个,第五消息为第四反馈信息对应的第一消息,第四反馈信息包括以下信息中的至少一种:第一节点成功接收;第一节点未成功接收;期待再次发送第五消息上承载的数据包;期待不再发送第五消息上承载的数据包;期待发送的数据包的标识。
上述可能的实施方式中,第一节点已成功接收用于指示第二节点上传新的数据包;第一节点未成功接收用于指示第二节点重传第四反馈信息对应的第一消息承载的数据包;希望再次发送第五消息上承载的数据包用于指示第二节点重传第四反馈信息对应的第一消息承载的数据包;希望不再发送第五消息上承载的数据包用于指示第二节点上传新的数据包;希望期望待发送的数据包的标识用于指示重传还是发送新的数据包,第二节点可以根据第四反馈信息重传或发送新的数据包,提高方案的可行性。
在一种可能的实施方式中,当第四反馈信息包括期待发送的数据包的标识时,若期待发送的数据包的标识与第五消息中数据包的标识相同,则第四反馈信息指示期待再次发送第五消息上承载的数据包;若期待发送的数据包的标识与第五消息的标识不同,则第四反馈信息指示期待不再发送第五消息上承载的数据包。
上述可能的实施方式中,第一节点可以在第四反馈信息中用与第五消息中数据包的标识相同的标识指示第二节点重传数据包,也可以用与第五消息的标识不同的标识指示第二节点发送新的数据包,该标识采用较少比特即可达到上述效果,节省反馈信息的资源。
在一种可能的实施方式中,该方法还包括:第一节点接收来自M个第二节点的N个第三消息;第一节点在第二资源上向M个第二节点发送第四信息,第四消息包括与N个第三消息一一对应的N个第二反馈信息。

上述可能的实施方式中,M个第二节点按照预先设置的排列顺序向第一节点发送N个第一消息,并且,按照相同的排列顺序向第一节点发送N个第三消息,即M个第二节点在不同的传输机会内的传输顺序不变,以减少第一节点向第二节点发送资源配置的次数。

上述可能的实施方式中,本申请应用于跳频通信,在第一跳频信道的第一时域资源中,第一节点先发送第二消息,再接收M个第二节点发送的N个第三消息,第二消息可以为M个第二节点确定N个第三消息提供依据,提高方案的可行性。同一跳频信道邻近的时间中,信道和干扰条件相似,收到第二消息的第二节点在同一跳频信道发送的成功率更高,可以提升传输效率;未收到第二消息的第二节点即使发送第三消息,传输成功率也较低,可选的,该第二节点可以不发送对应的第三消息,从而降低功耗。

具体实施方式
本申请实施例提供了一种信息传输的方法以及装置,用于减少主节点对从节点的反馈开销。
下面结合附图,对本申请的实施例进行描述,显然,所描述的实施例仅仅是本申请一部分的实施例,而不是全部的实施例。本领域普通技术人员可知,随着技术的发展和新场景的出现,本申请实施例提供的技术方案对于类似的技术问题,同样适用。
本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象,而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换,以便这里描述的实施例能够以除了在这里图示或描述的内容以外的顺序实施。此外,术语“包括”和“具有”以及他们的任何变形,意图在于覆盖不排他的包含,例如,包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元,而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
“至少一个”是指一个或者多个,“多个”是指两个或两个以上。“和/或”,描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B的情况,其中A,B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达,是指的这些项中的任意组合,包括单项(个)或复数项(个)的任意组合。例如,a,b,或c中的至少一项(个),可以表示:a,b,c,a和b,a和c,b和c,或,a和b和c,其中,a,b,c可以是单个,也可以是多个。
以及,除非有相反的说明,本申请实施例提及“第一”、“第二”等序数词是用于对多个对象进行区分,不用于限定多个对象的大小、内容、顺序、时序、优先级或者重要程度等。例如,第一配置信息和第二配置信息,只是为了便于描述而给予的名称,这两个配置信息可能是同一个配置信息,或者也可能是不同的配置信息。“第一”、“第二”这种名称, 也并不用于表示这两个配置信息的大小、内容、发送顺序、优先级或者重要程度等的不同。
本申请实施例涉及的信息传输的装置可以是车机、车载扬声器、车载麦克风等车载设备,也可以是手机、平板电脑、桌面型、膝上型、笔记本电脑、超级移动个人计算机(ultra-mobile personal computer,UMPC)、手持计算机、上网本、个人数字助理(personal digital assistant,PDA)、可穿戴电子设备、虚拟现实设备等电子设备。
下面首先对本申请实施例涉及的部分用语进行解释说明,以便于本领域技术人员理解。
(1)驾驶舱域控制器(cockpit domain controller或control domain cockpit,CDC):驾驶舱域控制器,简称车机。目前车机的功能除了传统的收音机、音乐时频播放、导航功能以外,已经带有蜂窝通信功能(3G,4G等),能结合汽车的CAN-BUS技术,实现人与车,车与外界的信息通讯,增强了用户体验及服务、安全相关的功能。
(2)主节点、从节点,在逻辑功能上区分的两类节点,分别是主节点和从节点。其中主节点管理从节点,具有分配资源的功能,负责为从节点分配资源;从节点根据主节点的调度,使用主节点分配的资源与主节点进行通信。节点可以为各种装置,例如主节点为手机,从节点为耳机,手机与耳机建立通信连接实现数据交互。手机管理耳机,手机具有分配资源的功能,可以为耳机分配资源。
(3)通信域,一组具有通信关系的通信节点,以及通信节点之间的通信连接关系组成的系统。其中,一个装置或设备可以在多个通信域中。例如当手机与耳机进行无线通信时,手机在包括手机与耳机在内的通信域a中,在通信域a中手机为主节点,耳机为从节点;然后当手机检测到CDC,并与该CDC建立无线连接后,手机也在包括手机与CDC在内的通信域b中,在通信域b中CDC为主节点,手机为从节点,手机听从该CDC的调度。通信域b中还可以包括其他从节点,如车载音箱、麦克等。
参照图1所示的一种通信分布系统的结构示意图,通信分布系统可以包括主节点和两个从节点,主节点和从节点之间可以进行消息交互,从节点向主节点发送消息,主节点可以对从节点的消息进行应答。
可以理解的是,图中示出了包含了1个主节点和2个从节点,但在实际场景中,还可以是更多的主节点或更多的从节点,具体数量因实际场景而定,此处不做限定。
本申请实施例所应用的无线通信场景,可以包括广域无线通信,例如包括多个网络设备与多个用户设备(user equipment,UE)之间的通信,其中,网络设备作为主节点,UE作为从节点,网络设备为UE分配资源,UE听从网络设备的调度。也可以包括短距无线通信,例如车内无线通信场景,例如包括CDC与车载音箱、车载麦克、手机之间的通信,手机与耳机等穿戴式设备之间的通信。还可以包括局域无线通信,例如多个接入点(access point,AP)与多个站点(station)之间的通信。
通常,车内无线通信链路的拓扑关系如图2所示。从图2可以看出,车内存在多个通信域,其中的一个通信域包括一个主节点和至少一个从节点,其中,主节点调度从节点,实现主从节点间互相传输业务数据。例如图2中,手机、耳机和穿戴式设备属于一个通信域,例如称为通信域1,其中手机是主节点,耳机和穿戴式设备是从节点;CDC、显示屏、麦克、音箱属于一个通信域,例如称为通信域2,其中CDC是主节点,显示屏、麦克和音 箱是从节点;无钥匙进入及启动(passive entry passive start,PEPS)系统、车身控制模块(body control module,BCM)、手机钥匙和车钥匙属于一个通信域,例如称为通信域3,其中PEPS系统是主节点,BCM、手机钥匙和车钥匙是从节点。另外,一个通信域的主节点也可以作为另一个通信域的从节点,例如,通信域1中的手机可以作为通信域2的从节点。或者,也可以从资源的角度定义通信域。例如,可以将一个节点分配的,用于该节点与其它节点通信的资源称为一个通信域,则该节点为该通信域的主节点,使用该通信域(资源)与该节点通信的其它节点为该通信域的从节点。
无线通信技术支持多路从节点到主节点的并行传输,例如多个麦克风同时向音频处理设备传输采集到的音频数据。但是,当多路从节点到主节点并发传输数据包时,主节点针对每个从节点的数据包需要分别发送反馈信息,导致主节点反馈的开销较高。
为解决上述问题,本申请实施例提供了一种信息传输的方法,该方法如下所述。
请参阅图3,如图3所示为本申请实施例提供的一种信息传输的方法一实施例,该方法包括:
301.M个第二节点向第一节点发送N个第一消息。
本申请实施例的通信分布系统可以适用于一个通信域中主节点和一个或多个从节点之间信息传输。该通信域包括一个第一节点和M个第二节点,其中,第一节点和第二节点可以都为从节点,也可以是第一节点为主节点,第二节点为从节点,本实施例对此不作限定。本申请实施例以第一节点为主节点,第二节点为从节点为例。M为大于或等于1的整数,N为大于或等于M的整数,即,M个第二节点中的每个第二节点向第一节点发送一个或多个第一消息,共计N个第一消息。
M等于1时,通信域中包括一个第一节点和一个第二节点,该第二节点可以向第一节点发送多个第一消息。
可选的,M个第二节点包含于第一通信组。具体的,第一通信组可以是上述通信域中的所有从节点组成的,其中,M个第二节点可以是该第一通信组中的全部或部分从节点。第一通信组还可以是在上述通信域中选择的部分从节点组成的,则该第一通信组完全由M个第二节点组成,示例性的,一个会场内的多个麦克风同时向音频处理设备传输采集到的音频数据,当第一通信组为会场内的所有麦克风时,M个第二节点为会场内的所有麦克风或者会场内除了不需要使用(或发送空数据包)的麦克风;第一节点也可以直接在会场内的麦克风中选择部分麦克风组成第一通信组,本申请实施例对第一通信组的构成不作限定。
302.第一节点在第一资源上向M个第二节点发送第二消息。
