Description

一种信息传输方法及装置 技术领域
本发明涉及通信技术领域，尤其是短距离通信。尤其涉及一种信息传输方法及装置。
背景技术
随着全球通信技术的不断发展，无线通信技术的发展速度与应用已经超过了固定通信技术，呈现出如火如荼的发展态势。智能运输设备、智能家居设备、机器人等智能终端正在逐步进入人们的日常生活中。
以智能终端为智能运输设备为例，车联网技术的发展与应用越来越受到人们的关注。由于相比现有的有线通信，车载无线可以进一步降低车内线束数量、长度、重量，以及与之对应的安装、维护、保养成本，车载通信技术有逐步无线化的趋势。随着车载应用的多样化，车内通信节点数量、类型都越来越多，对于车载通信的能力提出了更高的要求。
在不少无线通信场景中，在一定通信区域或范围内往往会存在多个通信域。如图1所示，图1表示车内通信链路的拓扑关系示意图。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，并具有为主从节点间的通信链路调度资源的功能。不属于通信域的节点(可以简称为外部节点，包括未加入过通信域的设备以及加入过通信域后又退出通信域的设备)可以通过加入通信域的过程转换为该通信域的从节点。外部节点加入通信域的过程中，首先要与通信域同步，并获取通信域的资源配置和支持的特性等系统信息。
由于不同的车型、不同类型的通信域支持不同的业务和不同的特性，主节点对从节点配置的时频资源不同，相应的，主节点发送给从节点的系统信息的格式也不相同。因此，如何进行信息传输，提高通信系统的可扩展性是本领域人员正在解决的技术问题。

具体实施方式
下面结合本发明实施例中的附图对本发明实施例进行描述。
本申请的说明书和权利要求书及所述附图中的术语“第一”、“第二”、“第三”和“第四”等是用于区别不同对象，而不是用于描述特定顺序。此外，术语“包括”和“具有”以及它们任何变形，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、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或单元。
在本文中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本文所描述的实施例可以与其它实施例相结合。
在本说明书中使用的术语“部件”、“模块”、“系统”等用于表示计算机相关的实体、硬件、固件、硬件和软件的组合、软件、或执行中的软件。例如，部件可以是但不限于，在处理器上运行的进程、处理器、对象、可执行文件、执行线程、程序和/或计算机。通过图示，在计算设备上运行的应用和计算设备都可以是部件。一个或多个部件可驻留在进程和/或执行线程中，部件可位于一个计算机上和/或分布在2个或更多个计算机之间。此外，这些部件可从在上面存储有各种数据结构的各种计算机可读介质执行。部件可例如根据具有一个或多个数据分组(例如来自与本地系统、分布式系统和/或网络间的另一部件交互的二个部件的数据，例如通过信号与其它系统交互的互联网)的信号通过本地和/或远程进程来通信。
本申请实施例中涉及的装置可以是车机、车载扬声器、车载麦克风等车载设备、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。
首先，对本申请中的部分用语进行解释说明，以便于本领域技术人员理解。
(1)CDC：Cockpit Domain Controller或Control Domain Cockpit，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)及Telematics，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；从节点听从主节点的调度，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。
(4)外部节点：不属于一个通信域的节点称为该通信域的外部节点。外部节点包括未加入过通信域的设备以及加入过通信域后又退出通信域的设备。外部节点可以通过加入通信域的过程转换为该通信域的从节点。
(5)上行传输为：从节点或外部节点向主节点发送数据信号或信令；下行传输为：主节点向从节点或外部节点发送数据信号或信令；上行传输和下行传输的资源配置信息简称为上下行资源配置信息，有时也把不区分上行或者下行的传输称为上下行传输。这里需要说明的是，“上行传输”和“下行传输”仅是为了区分传输方向，具体的方案中不局限于“上行”或者“下行”的文字表述。
(6)一个示例性的无线帧结构：如图2所示，图2表示一个示例性的无线帧结构示意图，一个无线帧包括下行传输部分和上行传输部分。一个无线帧由多个符号和保护间隔(guard period，GP)组成的，1个无线帧等于20.833微秒(us)，例如，一个无线帧的下行传输部分等于10.417us，一个无线帧的下行传输部分包括4个符号和保护间隔，4个符号分别为符号#0、符号#1、符号#2、符号#3，符号#0(黑色填充部分)包含1个含有循环前缀(cyclic prefix，CP)的正交频分复用(orthogonal frequency division Multiplexing，OFDM)符号，一个符号等于8.9842us，一个保护间隔等于1.4323us；一个无线帧的上行传输部分等于10.417us，一个无线帧的上行传输部分包括4个符号和保护间隔，4个符号分为为符号#4、符号#5、符号#6、符号#7，一个符号等于8.9842us，一个保护间隔等于1.4323us。
本申请实施例提供的信息传输方法所应用的无线通信场景，可以包括广域无线通信，例如包括多个基站与多个用户设备(user equipment，UE)之间的通信。也可以包括车内无线通信场景，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。
目前，发送系统信息的方式是通过周期性的发送主信息块(master information block，MIB)消息，其中MIB消息中包括一部分系统配置信息，其他部分系统配置信息由多个不同编号的系统信息块(system information blocks，SIB)消息发送，每个SIB消息都由下行控制信息(downlink control information，DCI)调度发送，相应的，若获得SIB消息，需要盲检用于调度SIB消息的DCI，实现逻辑比较复杂。而且在获得用于调度SIB消息的DCI或者SIB消息时，需要通过参考信号获得信道参数，然后根据该信道参数对用于调度SIB消息的DCI或者SIB消息进行均衡，因为参考信号的周期一般比较长，而且由于车载短距无线通信和环境的移动性比较低，参考信号比较稀疏，因此，就会造成较大的时延。为了解决上述问题，提高系统的可扩展性，本申请提出了如下解决方案。
为了便于理解本申请实施例的信息传输方法，下面具体以车内无线通信场景为例，进行说明。但本申请实施例的信息传输方法不限于车内通信场景。
如图3所示，图3是本申请实施例提供的信息传输方法的场景架构示意图，可以包括但是不限于第一设备和其他设备。其中，第一设备为一个通信域中的主节点，其他设备为该通信域中的从节点，或者外部节点。如当手机与耳机进行无线通信时，手机在包括手机和耳机的第一通信域中，在第一通信域中手机为主节点，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在内的第二通信域中，在第二通信域中CDC为主节点，手机为从节点，手机听从该CDC的调度。第二通信域中还可以包括其他从节点，如车载音响、麦克等。
请参见图4，图4是本发明实施例提供的一种信息传输的方法，该方法包括但不限于如下步骤：在下述一系列步骤中，除了同一条消息生成在发送之前，接收在发送之后，其它的步骤之间没有先后顺序关系的限制。
步骤S401：第一设备生成第一信号。
具体地，该步骤为可选的步骤。第一信号用于同步，第一信号可以用于时间和/或频率上的同步。其中，第一信号可以为同步信号块(synchronization signal block，SSB)、主同步信号(primary synchronization signal，PSS)和/或辅同步信号(secondary synchronization signal，SSS)中的至少一个。示例性的，第一设备可以根据通信域的类型、通信域的特征、通信域的身份标识中的一项或者多项生成第一信号，本申请实施例不做限定。
步骤S402：第一设备通过第一天线端口在第一时频资源上向其他设备发送第一信号。
具体的，收到所述第一信号的设备可以基于所述第一信号确定所述天线端口对应的信道参数，该信道参数用于收到所述第一信号的设备对通过该天线端口传输的数据进行信道解调。其中，所述第一信号可以具有周期性的特征，其周期由协议规定的，或者也可以是非周期性、经由触发发送的。
在一种可选的方案中，第一时频资源对应的时域资源由一个或者多个第一符号组成，该第一符号为某个第二类时间单元中的第N个符号，其中，N为正整数。具体地，第二类时间单元可以是无线帧、时隙或子帧。连续的多个无线帧、时隙或者子帧组成一个超帧，一个无线帧由多个子帧组成。1个时隙的长度通常小于等于1个子帧的长度。一种实现中，第一符号为至少一个无线帧中相同序号的符号，例如，在连续48个无线帧中，每个无线帧 中包括符号#0、符号#1、符号#2、符号#3、第一保护间隔、符号#4、符号#5、符号#6、符号#7和第二保护间隔，符号#0、符号#1、符号#2、符号#3、第一保护间隔、符号#4、符号#5、符号#6、符号#7和第二保护间隔分别对应的序号为1、2、3、4、5、6、7、8、9、10，那么第一符号为其中的一个或者多个无线帧中相同序号的符号，如某一个或多个无线帧中序号为3的符号，即符号#2。这里需要说明的是，上文所阐述的“序号”只是为了解释符号的顺序和位置，实际的通信系统中可以不存在实际的序号。
在一种示例中，第一符号为第二类时间单元中的第一个符号。例如，在一个连续48个无线帧中，每个无线帧中包括符号#0、符号#1、符号#2、符号#3、第一保护间隔、符号#4、符号#5、符号#6、符号#7和第二保护间隔，符号#0、符号#1、符号#2、符号#3、第一保护间隔、符号#4、符号#5、符号#6、符号#7和第二保护间隔分别对应的序号为1、2、3、4、5、6、7、8、9、10。第一符号为一个或多个第二类时间单元中的第一个符号，如上述一个或多个无线帧中序号为1的符号，即该连续48个无线帧中，存在一个或多个无线帧，其中中的符号#0都为第一符号。
本申请的方案中，可以配置或者定义第一符号为一个或多个第二类时间单元中的第一个符号，第一符号是用于下行传输的符号，而第二类时间单元中的第一个符号在各种上下行资源配置中都是用于下行传输的符号。因此该方案可以保证各种上下行资源配置的第二类时间单元中都可以存在第一符号。
在又一种可选的方案中，第一时频资源的频域资源为20兆赫带宽中所有有效的频域资源。其中，所述20兆赫带宽中所有有效的频域资源为所述20兆赫带宽中除去作为保护间隔的带宽之外的频域资源；或者，为所述20兆赫带宽中除去作为保护间隔的带宽以及直流分量子载波之外的频域资源。具体的，按480千赫兹(kHz)子载波间隔确定20兆赫(MHz)信道一共可以包含41.67个子载波，而实际中20MHz带宽的两边的部分带宽作为保护间隔，除保护间隔外剩余例如40个子载波，这40个子载波中包含1个或多个用于抑制直流分量的子载波，简称直流分量子载波。那么，所述第一时频资源的频域资源可以为上述20兆赫带宽中的40个子载波或者为上述20兆赫带宽中的40个子载波中除上述一个或多个直流分量子载波之外的子载波。通过使用尽可能多的子载波传输信号或信令，可以获取最大的频率分集增益。
步骤S403：其他设备接收来自第一设备的第一信号。
步骤S404：第一设备生成第一消息。

具体地，第二类时间单元可以为一个无线帧，第二类时间单元的每个符号包括两种情况：第一种情况，第二类时间单元的每个符号包括一个第二类时间单元中的所有符号中的每一个符号。例如，如图10所示，图10表示一个无线帧中的符号的示意图，1个超帧包括48个无线帧(第二类时间单元)，该无线帧包括符号#0、符号#1、符号#2、符号#3、第一保护间隔、符号#4、符号#5、符号#6、符号#7和第二保护间隔，第二类时间单元中的所有符号包括符号#0、符号#1、符号#2、符号#3、符号#4、符号#5、符号#6、符号#7。
第二种情况，第二类时间单元的每个符号包括一个第二类时间单元中可用于第一业务类型的业务数据的每一个符号，这里不包括在某个或某些第二类时间单元中已被指示用于传输第一类控制信令或信号的符号(以下简称用于传输第一类控制信令或信号的符号为特殊符号)。如图10所示，图10表示一个无线帧中的符号的示意图，1个超帧包括48个无线帧(第二类时间单元)，该无线帧包括符号#0、符号#1、符号#2、符号#3、第一保护间隔、符号#4、符号#5、符号#6、符号#7和第二保护间隔，该48个无线帧中，有60个特殊符号(第一符号和/或第二符号)前12个无线帧中符号#2、符号#3为特殊符号(被指示用于第一类控制信令或信号的符号)，第13-第48个无线帧中符号#3为特殊符号(被指示用于第一类控制信令或信号的符号)，那么，此时第五消息用于指示48个无线帧中，每一个无线帧中的符号#0、符号#1、符号#4、符号#5、符号#6和符号#7中的用于第一业务类型的业务数据的频域资源。
例如，在48个无线帧中，有60个特殊符号(第一符号和/或第二符号)，前2个无线帧中符号#0和符号#3为特殊符号，第3-第12个无线帧中符号#2和符号#3为特殊符号，第13-第48个无线帧中符号#3为特殊符号，那么，此时第五消息用于指示48个无线帧中前2个无线帧中，每一个无线帧中的符号#1、符号#2、符号#4、符号#5、符号#6和符号#7中的用于第一业务类型的业务数据的频域资源以及48个无线帧中第3-第48个无线帧中，每一个无线帧中的符号#0、符号#1、符号#4、符号#5、符号#6和符号#7中的用于第一业务类型的业务数据的频域资源。在一种可能的实现方式中，前2个无线帧中符号#1、符号#2中的用于第一业务类型的业务数据的频域资源分别与第3-第48个无线帧中符号#0、符号#1中的用于第一业务类型的业务数据的频域资源相同，则对于这48个无线帧，指示6个符号中每个符号中的用于第一业务类型的业务数据的频域资源，即可确定这48个无线帧中用于第一业务类型的业务数据的时频资源，该6个符号在前2个无线帧中依次符号#1、符号#2、符号#4、符号#5、符号#6和符号#7对于，在第3-第48个无线帧中依次与符号#0、符号#1、 符号#4、符号#5、符号#6和符号#7对应。这样可以简化指示方式，并增加可用于第一业务类型的业务数据传输的符号数量。
在又一种可选的方案中，第六时频资源对应的时域资源由一个或者多个第一符号组成，第一符号为第二类时间单元中的第N个符号，其中N为正整数，可选的，第一符号为第二类时间单元中的第一个符号。具体可以参照步骤S402，此处不再进行赘述。
在又一种可选的方案中，第六时频资源的频域资源包括20兆赫带宽中所有有效的频域资源。具体可以参照步骤S402，此处不再进行赘述。
步骤413：其他设备在第六时频资源上接收来自第一设备的第五消息。
具体地，该第五消息用于指示第一业务类型的业务数据的资源。
上述第一消息、第二消息、第三消息、调度信息、第五消息都是第一设备通过单播或者多播的形式发给其他设备，其他设备可以为一个或者多个设备，第一消息、第二消息、第三消息、调度信息、第五消息中包括的内容为第一设备为其他设备配置的信息。而接下来将描述第一设备具体和第二设备之间信息交互，即主节点具体和某一个从节点之间信息交互，其中第二设备可以为其他设备中的具体某一个设备。
在一种可选的方案中，第一设备向第二设备发送第四消息，第四消息用于指示第五资源，第五资源用于第二设备的第二控制类信号或者信令，第二控制类信号或者信令包括：
向所述第二设备发送的同步信号、确认/否认反馈信息、广播消息、系统消息、物理层控制信令、高层信令、解调参考信号、相位跟踪参考信号、定位参考信号和信道状态信息参考信号中的一项或者多项，和/或

具体地，该第二控制类信号或信令具体为第一设备与第二设备之间传输的信号或者信令，且第五资源用于第二设备的信号或信令可以是指用于第一设备向第二设备发送第二类控制类信号或信令，和/或第一设备接收来自于第二设备的控制类信号或信令，确认反馈信息可以为肯定应答(acknowledgment，ACK)反馈，否认反馈信息可以为否定应答(negative-acknowledgment，NACK)反馈。相位跟踪参考信号用于相位追踪，定位参考信号用于定位，信道状态信息参考信号用于估计信道状态。在一种示例中，第四消息用于指示第五资源，根据第四消息能确定第五资源，第五资源用于第一设备向第二设备发送高层信令；在又一种示例中，第四消息用于指示第五资源，根据第四消息能确定第五资源，第五资源用于第一设备向第二设备发送高层信令和第一设备接收来自与第二设备的信道反馈信息。
通过第一设备向第二设备发送第四消息，第四消息用于指示第二设备的第二控制类信号或者信令的资源。第一设备直接为第二设备配置第二控制类信号或者信令的资源，通过系统配置资源的方式，避免资源不够用和过分浪费，提高了系统配置资源的灵活性。
