Description

通信方法、装置、设备及计算机可读存储介质 技术领域
本申请涉及通信领域,尤其涉及短距离通信领域,例如座舱域通信。本申请具体提供了一种通信方法、一种通信装置、一种通信设备以及一种计算机可读存储介质。
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固定通信技术,呈现出如火如荼的发展态势。
例如,车联网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。车载应用的多样化,使得车内通信节点数量、类型都越来越多,对于车载通信的能力提出了更高的要求。
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。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),主从节点间建立通信连接实现数据交换。该多个通信域内有各自的通信链路,因此需要解决通信域之间不同通信链路间相互干扰的问题。
还是以车辆为例,如图1示出的车内通信链路的拓扑关系示意图。车内存在多个通信域,车内会出现有时存在,有时消失的通信域。也就是说,车内通信域的数量往往会动态的增加或减少。例如以手机为主节点的通信域随着手机持有人上车而存在,随着手机持有人下车而消失。其中,每个通信域内有各自的通信链路,车载通信无线化需要解决通信域之间(可以简称域间)不同通信链路间互相干扰的问题。当两个同处于车内的无线通信节点使用有重叠或交叠的时频资源通信时,对应的两个通信链路就会形成互相干扰。
现有技术中,例如蓝牙技术,采用跳频的方式通信来实现干扰随机化。如图2示出的跳频通信示意图。通信链路使用的频率资源随着时间的不同,伪随机的变化。不同的通信链路变化规律不同,即使偶尔使用了相同的资源,下一个跳频驻留时间就会错开,从而不会造成两条通信链路的持续干扰。
然而,上述现有技术仅适用于低负载情况,即邻近的空间内仅存在较少数量的通信链路的情况。中高负载下,由于多条通信链路使用的资源频繁重叠,会表现出明显的干扰,链路通信质量显著下降,甚至无法完成正常通信。
发明内容
本申请实施例公开了一种通信方法、一种通信装置、一种通信设备以及一种计算机可读存储介质,能够解决中高负载下不同通信链路使用的资源重叠的概率仍然较高,通信链路间互相干扰较为严重的技术问题。
第一方面,本申请实施例提供一种通信方法,该方法包括:
接收来自第二装置的第一信息,所述第一信息用于指示第一时频资源;
根据所述第一信息,通过第二时频资源向至少一个第三装置发送第二信息,所述第二信息包含第一同步信号,以及,业务数据、控制信息或者系统信息中的至少一个,所述第二时频资源为所述第一时频资源的子集。
本申请实施例通过第二装置向第一装置指示第一时频资源,以使第一装置通过该第一时频资源的子集来与主节点为第一装置的通信域内的从节点,例如第三装置,进行通信,包括通过第二时频资源向至少一个第三装置发送第一同步信号,以及,业务数据、控制信息或者系统信息中的至少一个。该第二装置指示的第一时频资源是与该第二装置所在通信域所使用的时频资源不交叠。从而实现或建立起来的域间通信资源协调机制,能够避免资源冲突,解决了现有技术在中高负载下不同通信链路使用的资源重叠的概率仍然较高,通信链路间互相干扰较为严重的技术问题。
在一种可能的实现方式中,该方法还包括:
通过第二时频资源接收来自至少一个第三装置的业务数据。
本申请实施例中第一装置通过第二时频资源向至少一个第三装置发送第一同步信号,并发送系统信息和/或控制信息,还可以通过第二时频资源接收到来自至少一个第三装置的业务数据。避免了与其他通信域的通信链路的互相干扰,解决了现有技术在中高负载下不同通信链路使用的资源重叠的概率仍然较高,通信链路间互相干扰较为严重的技术问题。
在一种可能的实现方式中,所述第一信息承载于第二同步信号、广播消息、单播消息或组播消息中的至少一个。
本申请实施例中第一装置通过接收第二装置发送的第二同步信号、广播消息、单播消息或组播消息中的至少一个,即可获知第二装置指示的第一时频资源,从而实现或建立起来本申请的域间通信资源协调机制。
在一种可能的实现方式中,所述第一信息承载于第二同步信号,或者该第二同步信号对应于所述第一时频资源。
本申请实施例第二同步信号对应于所述第一时频资源,例如第一时频资源与第二同步信号的时频资源的相对位置存在预设的关系;或者用于指示第一时频资源的信息承载于第二装置发送的第二同步信号中,那么第一装置在检测到第二装置发送的该第二同步信号即可获知指示的第一时频资源,例如第一时频资源与第二同步信号的时频资源的相对位置存在多种可能的预设关系,第二同步信号承载的信息指示第一时频资源与第二同步信号的时频资源的相对位置是其中的哪一种,第二同步信号承载信息的方式包括但不限于第二同步信号中的标识编号、第二同步信号的循环移位量等。由于同步信号的覆盖区域往往大于系统信息或控制信息,也就是说相比系统信息或控制信息,第一装置可以在距离第二装置还比较远的时候,即可获知指示的第一时频资源,从而实现资源协调。在两个通信域之间的距离还比较远时,两个通信域内的通信链路相互干扰很小或无相互干扰,因此第一信息承载于第二同步信号可以最大程度地避免两个通信域内通信链路之间的干扰。
在一种可能的实现方式中,所述第一信息承载于广播消息中。
本申请实施例用于指示第一时频资源的信息承载于第二装置的广播消息中,那么第一装置在检测到第二装置广播的该广播消息即可获知指示的第一时频资源。从而实现或建立起来的域间通信资源协调机制,能够避免资源冲突,解决了现有技术在中高负载下不同通 信链路使用的资源重叠的概率仍然较高,通信链路间互相干扰较为严重的技术问题。
在一种可能的实现方式中,所述第一信息承载于第二同步信号和广播消息,所述第二同步信号和广播消息共同指示所述第一时频资源。
本申请实施例通过第二同步信号和广播消息共同指示第一时频资源的信息,那么第一装置在检测到第二装置发送的第二同步信号和广播消息,解析该第二同步信号和广播消息,即可获知指示的第一时频资源。从而实现或建立起来的域间通信资源协调机制,能够避免资源冲突,解决了现有技术在中高负载下不同通信链路使用的资源重叠的概率仍然较高,通信链路间互相干扰较为严重的技术问题。
在一种可能的实现方式中,所述第一信息承载于第一组播消息或第一单播消息中的至少一个。
本申请实施例通过第一组播消息或第一单播消息来指示第一时频资源的信息,那么第一装置在检测到第二装置发送的第一组播消息或第一单播消息,即可获知指示的第一时频资源。或通过第一组播消息和第一单播消息共同指示第一时频资源的信息,那么第一装置在检测到第二装置发送的第一组播消息和第一单播消息,解析该第一组播消息和第一单播消息,即可获知指示的第一时频资源。从而实现或建立起来的域间通信资源协调机制,能够避免资源冲突,解决了现有技术在中高负载下不同通信链路使用的资源重叠的概率仍然较高,通信链路间互相干扰较为严重的技术问题。
本申请实施例可通过第二装置给多个不同的第一装置发送不同的第一单播消息,从而为不同的域(域对应主节点为不同的第一装置)分配不同的第一时频资源,以实现多个域的资源协调,能够避免资源冲突,在多个域的场景下,解决了现有技术在中高负载下不同通信链路使用的资源重叠的概率较高,通信链路间互相干扰较为严重的技术问题。
在一种可能的实现方式中,所述方法还包括:
向所述至少一个第三装置发送资源变更信息,所述资源变更信息用于指示所述第二时频资源的信息。
本申请实施例在根据所述第一信息,向至少一个第三装置发送资源变更信息,以指示使用该第二时频资源。即实现第一装置和至少一个第三装置之间通过该第二时频资源进行通信。指示使用该第二时频资源的方式可以是指示第二时频资源相关的配置信息,例如上下行配比类型、资源调度或映射类型等;或者是与第二时频资源有关的时域和/或频域资源的信息,例如定时提前量、载波号、频率偏置等。
在一种可能的实现方式中,可以在通过第二时频资源向至少一个第三装置发送第二信息之前,向至少一个第三装置发送资源变更信息。
在一种可能的实现方式中,也可以在通过第二时频资源向至少一个第三装置发送第二信息的同时或之后,向至少一个第三装置发送资源变更信息。本申请实施例的通信方法不限定第一装置通过第二时频资源向至少一个第三装置发送第二信息,与向至少一个第三装置发送资源变更信息的先后顺序。
在一种可能的实现方式中,所述方法还包括:
向所述第二装置发送资源请求信息。
本申请实施例可以在接收来自第二装置的第一信息之前,向该第二装置发送资源请求 信息,以请求资源。随后即接收到来自该第二装置的第一信息,此时该第一信息并非广播消息或同步信号;该第一信息可以承载于单播消息或组播消息中至少一个。该单播消息或组播消息可以指示有一段专有的,不会与其他通信域的时频资源交叠的时频资源,第一装置可以通过指示的这段时频资源向至少一个第三装置发送该第二信息。在本场景的一种可能的实现方式中,向第二装置发送资源请求信息之前,第一装置已经与第二装置建立了连接。
在另外的场景中,本申请实施例可以在接收来自第二装置的第一信息之后,向该第二装置发送资源请求信息,以请求资源。从而可以向第二装置请求到一段专有的,不会与其他通信域的时频资源交叠的时频资源,用于向至少一个第三装置发送该第二信息。
在一种可能的实现方式中,所述资源请求信息包含:
所述第一装置的通信业务量、所述第一装置的资源需求、或所述第一装置的信道质量中的至少一个。

本申请实施例第一装置还可以是向第二装置发送资源请求信息后,接收来自第二装置的资源重配信息,表明该第二装置重新给第一装置分配第四时频资源,隐含该第二装置不允许该第一装置对第三时频资源的占用或占有。以使第一装置通过第五时频资源向至少一个第三装置发送第三信息。
在一种可能的实现方式中,所述第一时频资源在时域上不连续。

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。

为了便于理解本申请实施例的通信方法,下面具体以车内无线通信场景为例,进行说明。但本申请实施例的通信方法不限于车内通信场景。
如图3示出的本申请实施例提供的通信方法的场景架构示意图,可以包括但是不限于第一装置、第二装置、第三装置和第四装置。其中,第一装置可以为手机;第二装置可以为CDC;第三装置可以包括多个,例如耳机、手环等可穿戴式设备;第四装置也可以包括多个,例如车载音箱、车载麦克等设备。由上可知,所述第一装置和第二装置不同。在某些可能的场景中,第一装置与第二装置的类型可以相同,例如两者均为CDC,但是第一和 第二装置代表不同的CDC。
第二装置可以是车内无线通信场景中的对通信资源进行分配、协调等控制管理的设备。第二装置与至少一个第四装置建立通信连接,形成第二通信域。第一装置与至少一个第三装置建立通信连接,形成第一通信域。
在一种可能的实现方式中,本申请实施例的场景架构还可以包括更多装置形成的通信域,例如第五装置和第六装置,本申请不作限制。
下面结合图4示出的本申请实施例提供的通信方法的流程示意图进行说明,可以包括如下步骤:
步骤S400:第二装置发送第一信息。
可选的,所述第二装置确定第一时频资源,并通过所述第一信息指示所述第一时频资源。
具体地,所述第一信息用于指示第一时频资源。该第一时频资源可以是第二装置为目标通信域预留的资源池,该目标通信域可以为能检测到第二通信域,但不受第二通信域资源管理的通信域。该第一时频资源不用于该第二通信域的域内通信,也不用于受第二通信域资源管理的通信域的域内通信。
在一种可能的实现方式中,该第一信息可以包含第二同步信号、广播消息、单播消息或组播消息中的至少一个。也就是说,第二装置可以通过发送第二同步信号来发送第一信息,也可以通过广播发送广播消息来发送第一信息,等等。
其中,当该第一信息是单播消息或组播消息中的至少一个时,该目标通信域也可以为能检测到第二通信域,受第二通信域分配资源池,但该第二通信域不负责具体调度的通信域。
步骤S402:第一装置接收来自第二装置的第一信息;
具体地,第一通信域为属于该目标通信域的其中一个通信域,即该第一通信域的第一装置(该第一通信域的主节点)检测到了该第二通信域,那么该第一装置可以接收到该第二装置发送的第一信息。
步骤S404:第一装置根据所述第一信息,通过第二时频资源向至少一个第三装置发送第二信息;
具体地,第一装置解析该第一信息,获知到指示的该第一时频资源,通过第二时频资源向第一通信域内的一个或多个第三装置来发送第二信息,即通过该第一时频资源的子集向第一通信域内的一个或多个第三装置来发送第二信息。
在一种可能的实现方式中,该第二信息包含第一同步信号,以及,业务数据、控制信息或者系统信息中的至少一个。第一装置通过该第二时频资源向第三装置发送第一同步信号,表明该第一装置在第一通信域内为主节点,第三装置为从节点。第一装置为第一通信域内主从节点间的通信调度通信资源。
具体地,本申请各个实施例中的同步信号(包括第一同步信号、第二同步信号和第三同步信号)是由主节点发送的信号,可以具有周期性的特征,用于其他装置与该主节点所在通信域的同步,或者也可以是非周期性、经由触发发送的。业务数据是承载业务的数据,例如音频数据或视频数据。控制信息可以为应用层的控制信息,例如音量调节信息等;也 可以为接入层的控制信息,例如调度信令。系统信息是用来指示通信域的基本配置参数的信息,例如上下行配比信息,系统带宽信息,等等。这里只是示例性的对上述信号或者信息进行说明,本申请同样覆盖功能类似的其它类型的信息。
进一步可选的,所述方法还可以包括步骤S406:第二装置通过目标时频资源用于第二装置与至少一个第四装置进行通信;所述目标时频资源与所述第一时频资源不交叠。
具体地,第二通信域的域内通信是通过目标时频资源来进行的。由于第二通信域的域内通信资源是由第二装置来调度的,可以实现目标时频资源与第一时频资源不交叠,因此第二通信域内的通信链路与第一通信域内的通信链路之间没有干扰。从而实现或建立起来的域间通信资源协调机制,能够避免资源冲突,解决了现有技术在中高负载下不同通信链路使用的资源重叠的概率仍然较高,通信链路间互相干扰较为严重的技术问题。
其中,本申请实施例不限定步骤S406的执行顺序,该步骤S406不一定必须在步骤S404之后执行,可以在步骤S400到步骤S404的任意步骤之间执行,也可以与步骤S400到步骤S404的其中一个步骤同时执行,也可以在步骤S400之前执行。
其中,通信域内的主节点和从节点之间的通信可以包括以下至少一项:
主节点发送同步信号和/或参考信号给从节点;
主节点发送系统信息和/或调度信息(包括资源调度、可用资源、调制编码方式信息中的至少一种)给从节点;
主节点发送业务数据给从节点和/或从节点发送业务数据给主节点。
下面结合多个实施例来举例说明:
实施例一,第一信息承载于第二同步信号:
如图5示出本申请提供的另一实施例的通信方法的流程示意图,可以包括如下步骤:
步骤S500:第二装置发送第二同步信号;
具体地,本申请实施例第二装置可以以广播的方式发送第二同步信号。该第二同步信号对应于第一时频资源,或者说第一信息承载于该第二同步信号。该第一信息用于指示第一时频资源,即该第二同步信号可以携带有指示信息,以指示该第一时频资源。
在一种可能的实现方式中,指示该第一时频资源的方式可以是指示第一时频资源相关的配置信息,例如上下行配比类型、资源调度或映射类型等;或者是与第一时频资源有关的时域和/或频域资源的信息,例如定时提前量、载波号或频率偏置等。
其中,在步骤S500之前,第二装置可以确定了目标时频资源,第二装置通过该目标时频资源与至少一个第四装置进行通信。该目标时频资源与该第一时频资源不交叠。这里的不交叠是指两个时频资源上不存在任何重叠。
进一步,所述方法还包括步骤S502:第一装置接收来自第二装置的第二同步信号;
具体地,第一装置接收到该第二同步信号,即相当于检测到第二通信域,比如驾驶员或乘客拿着手机(即第一装置)进入车内或准备进入车内,那么手机即检测到CDC的第二通信域。
其中,第一装置除了发送第二同步信号,还可以发送系统信息和控制信息。而第二同步信号的覆盖区域远大于该系统信息和控制信息的覆盖区域。也就是说,第一装置与第二 装置相距比较远时,第一装置就可接收到该第二同步信号,当第一装置再靠近第二装置时,才接收到该系统信息和控制信息。
可选的,所述方法包括步骤S504:第一装置根据第二同步信号,确定上述第二时频资源;
具体地,第一装置可以解析该第二同步信号,获知指示的第一时频资源。然后从该第一时频资源中确定出第二时频资源,其中该第二时频资源为该第一时频资源的子集。也就是说,第一装置从第一时频资源中选取一部分时频资源,用于第一通信域内的通信。
步骤S506:第一装置向至少一个第三装置发送资源变更信息;
具体地,所述资源变更信息用于指示所述第二时频资源的信息。也就是说,通过该资源变更信息,第一装置可以向该至少一个第三装置指示时频同步调整、变更的资源(变更为第二时频资源)以及资源变更时间等。
其中,本申请各个实施例中的时频同步调整可以包括时间同步调整和/或频率同步调整。其中,向该至少一个第三装置指示时间同步调整,例如可以是向该至少一个第三装置指示定时调整量;向该至少一个第三装置指示频率同步调整,例如可以是向该至少一个第三装置指示频域偏移量。
在一种可能的实现方式中,该资源变更信息指示该第二时频资源的方式可以是指示第二资源相关的配置信息,例如上下行配比类型、资源调度或映射类型等;或者是与第二资源有关的时域和/或频域资源的信息,例如定时提前量、载波号或者频率偏置等。本申请实施例不作限制,只要第三装置接收到该资源变更信息,能从该资源变更信息中获知指示的第二时频资源即可。
其中,在本申请各个实施例中,该资源变更信息也可以仅通知资源变更,不指示变更后的资源具体是什么,即不指示变更到哪块资源上。后续由第三装置重新确定新的第二时频资源,例如第三装置通过搜索检测到第一装置在第二时频资源上发的同步信号(可选的,还接收到第一装置在第二时频资源上发的系统消息),来确定出该第二时频资源。
步骤S508:第一装置通过第二时频资源向至少一个第三装置发送第二信息;
具体地,在资源变更完成或资源切换完成之后,第一装置即可通过第二时频资源向至少一个第三装置发送第二信息,也就是说实现了通过第二时频资源进行第一通信域的通信。
其中,该第二信息可以包含第一同步信号,以及,参考信号、业务数据、控制信息或者系统信息中的至少一个。
在一种可能的实现方式中,步骤S508还可以包括第一装置通过该第二时频资源接收来自至少一个第三装置的业务数据。
进一步,所述方法还包括步骤S510:第一装置向第二装置发送资源请求信息;
具体地,虽然当前第一装置实现了通过第二时频资源向至少一个第三装置发送第二信息,由于第二装置一直在对外发送第一信息,以指示该第一时频资源。为了避免后续的装置获知到指示的第一时频资源,也选用与该第二时频资源重叠的资源进行域内通信,造成干扰。本申请实施例中,第一装置可以向第二装置发送资源请求信息,以重新请求时频资源。
其中,步骤S510之前,还可以包括第一装置在完成与第二装置的同步后,即相当于第 一装置实现了通过第二时频资源向至少一个第三装置发送第二信息后,该第一装置发起与该第二装置建立通信连接,以作为从节点接入该第二通信域。在第一装置完成接入该第二通信域后,执行步骤S510该第一装置向该第二装置发送资源请求信息。
可选的,步骤S510之前,也可以第一装置与第二装置进行同步后,该第一装置没有发起与该第二装置建立通信连接,没有作为从节点接入该第二通信域,即执行步骤S510该第一装置向该第二装置发送该资源请求信息。或者还可以第一装置没有与第二装置进行同步,即执行步骤S510该第一装置向该第二装置发送该资源请求信息。
在一种可能的实现方式中,本申请实施例的资源请求信息可以包含:
所述第一装置的通信业务量、所述第一装置的资源需求、或所述第一装置的信道质量中的至少一个。
步骤S512:第二装置根据资源请求信息确定第四时频资源;
具体地,第二装置接收到第一装置发送的资源请求信息后,获知需要为该第一装置重新分配通信资源,那么该第二装置即确定出第四时频资源。其中,该第四时频资源可以与目标时频资源不交叠,也可以与目标时频资源交叠。当第四时频资源与目标时频资源交叠时,在以该第二装置为主节点的通信域内,第二装置可以指示使用目标时频资源中该第四时频资源以外的通信资源进行通信。
在一种可能的实现方式中,当资源请求信息包含:该第一装置的通信业务量、该第一装置的资源需求、或该第一装置的信道质量中的至少一个时,上述信息可以用于第二装置为第一装置分配通信资源,以及管理和回收通信资源,提高通信资源的利用效率,可以更好地完成对通信资源的分配。
步骤S514:第二装置向第一装置发送资源重配信息;
具体地,该资源重配信息用于指示第四时频资源;该资源重配信息可以承载于单播消息或组播消息。
步骤S516:第一装置接收来自第二装置的资源重配信息;
步骤S518:第一装置根据所述资源重配信息,通过第五时频资源向至少一个第三装置发送第三信息。
具体地,第一装置在接收到资源重配信息后,解析该资源重配信息,获知指示的第四时频资源。然后从该第四时频资源中确定出第五时频资源,其中该第五时频资源为该第四时频资源的子集。也就是说,第一装置从第四时频资源中选取一部分时频资源,用于第一通信域内的通信。然后,第一装置可以向至少一个第三装置发送资源变更信息,该资源变更信息用于指示该第五时频资源的信息。也就是说,通过该资源变更信息,第一装置可以向该至少一个第三装置指示时频同步调整、变更的资源(变更为第五时频资源)以及资源变更时间等中的至少一个。在其中一种可能的实现方式中,第一装置可以通过第二时频资源向至少一个第三装置发送资源变更信息。
在一种可能的实现方式中,该资源变更信息可以是第五时频资源的配置信息,或者是与第五时频资源有关的时域和/或频域的信号,例如载波号等。本申请实施例不作限制,只要第三装置接收到该资源变更信息,能从该资源变更信息中获知指示的第五时频资源即可。
其中,本申请实施例中的第四时频资源与目标时频资源不交叠,第四时频资源也可以 与第一时频资源不交叠或不交叠。
在资源变更完成或资源切换完成之后,第一装置即可通过第五时频资源向至少一个第三装置发送第三信息,也就是说实现了通过第五时频资源进行第一通信域的通信。
其中,该第三信息包含第三同步信号,以及,参考信号、业务数据、控制信息或者系统信息中的至少一个。该第三信息是本申请资源重配后第一装置发送给至少一个第三装置的信息,该第二信息是本申请资源重配之前第一装置发送给至少一个第三装置的信息。该第三同步信号用于在本申请资源重配后该第三装置与以该第一装置为主节点的通信域的同步;而该第一同步信号用于在本申请资源重配之前该第三装置与以该第一装置为主节点的通信域的同步。该第三信息包含的业务数据、控制信息或者系统信息是申请资源重配后的数据或信息;而该第二信息包含的业务数据、控制信息或者系统信息是申请资源重配之前的数据或信息。
本申请实施例中,用于指示第一时频资源的信息承载于第二装置发送的第二同步信号中,那么第一装置在检测到第二装置发送的该第二同步信号即可获知指示的第一时频资源。由于同步信号的覆盖区域往往大于系统信息或控制信息,也就是说相比系统信息或控制信息,第一装置可以在距离第二装置还比较远的时候,即可获知指示的第一时频资源,从而实现资源协调。在两个通信域之间的距离还比较远时,两个通信域内的通信链路相互干扰很小或无相互干扰,因此第一信息承载于第二同步信号可以最大程度地避免两个通信域内通信链路之间的干扰。
另外,本申请实施例在第一装置向第二装置发送资源请求信息之前,也就是说在真正协调之前,第一装置先使用第二装置预留的资源(即第一时频资源)的子集进行域内通信,可以很好地保证资源协调过程中无干扰且业务不中断。并且在第一装置向第二装置发送资源请求信息之后,第二装置为第一装置配置了该第一装置作为主节点的通信域的通信时频资源(即第四时频资源),从而实现或建立起来的域间通信资源协调机制,能够避免资源冲突,解决了现有技术在中高负载下不同通信链路使用的资源重叠的概率仍然较高,通信链路间互相干扰较为严重的技术问题。
如图6示出本申请提供的另一实施例的通信方法的流程示意图,可以包括如下步骤:
步骤S600:第二装置发送第二同步信号;
步骤S602:第一装置接收来自第二装置的第二同步信号;
步骤S604:第一装置根据第二同步信号,确定第二时频资源;
步骤S606:第一装置向至少一个第三装置发送资源变更信息;
步骤S608:第一装置通过第二时频资源向至少一个第三装置发送第二信息;
具体地,步骤S600至步骤S608可以对应参考图5实施例中步骤S500至步骤S508的描述,这里不再赘述。
步骤S610:第一装置向第二装置发送资源占用信息;
具体地,该资源占用信息是该第一装置对应的资源占用信息,用于指示第三时频资源。该第三时频资源包含第二时频资源。进一步,该第三时频资源还可以包含该第二时频资源以外的资源。
其中,步骤S610之前,还可以包括第一装置在完成与第二装置的同步后,即相当于第一装置实现了通过第二时频资源向至少一个第三装置发送第二信息后,该第一装置发起与该第二装置建立通信连接,以作为从节点接入该第二通信域。在第一装置完成接入该第二通信域后,执行步骤S610该第一装置向该第二装置发送资源占用信息。
可选的,步骤S610之前,也可以第一装置与第二装置进行同步后,该第一装置没有发起与该第二装置建立通信连接,没有作为从节点接入该第二通信域,即执行步骤S610该第一装置向该第二装置发送该资源占用信息。或者还可以第一装置没有与第二装置进行同步,即执行步骤S610该第一装置向该第二装置发送该资源占用信息。
步骤S612:第二装置接收资源占用信息;
步骤S614:第二装置发送针对所述资源占用信息的确认信息,或者第二装置发送资源重配信息;
具体地,第二装置接收到第一装置的资源占用信息后,确认该第一装置是否可以占用该第三时频资源。若确认,则第二装置向该第一装置发送针对该资源占用信息的确认信息,也就是说第二装置认可第一装置对该第三时频资源的占用。否则,则第二装置向该第一装置发送资源重配信息,以指示第一装置可以占用的时频资源。
其中,若第二装置认可第一装置对该第三时频资源的占用之后,第二装置可以重新确定预留的资源池,也就是重新确定其他时频资源为第一时频资源。那么后续第二装置发送的第一信息,向目标通信域指示的是重新确定后的第一时频资源,即第一时频资源变更了,变更后的第一时频资源同样可以与目标时频资源不交叠。
需要说明的是,若第二装置确认不可以,也就是说不认可第一装置对该第三时频资源的占用。比如第二装置发现该第一通信域占用的该第三时频资源与其他通信域内的时频资源冲突了(即发生了交叠),例如两个手机几乎同时检测到第二通信域,即几乎同时接收到来自第二装置的第一信息的情况;或者第二装置不希望重新确定预留的资源池,也就是说不希望变更原来的第一时频资源,那么第二装置确认该第一装置不可以占用该第三时频资源,向该第一装置发送资源重配信息,以指示第一装置可以占用的时频资源。
在一种可能的实现方式中,第二装置确认该第一装置不可以占用该第三时频资源后,第二装置可以直接根据该资源占用信息为第一装置确定第四时频资源。其中,该资源占用信息也可以包含:该第一装置的通信业务量、该第一装置的资源需求、或该第一装置的信道质量中的至少一个。那么第二装置可以根据或参考该资源占用信息包含的上述信息为第一装置确定第四时频资源。
在一种可能的实现方式中,第二装置确认该第一装置不可以占用该第三时频资源后,第二装置可以与第一装置交互以获知:该第一装置的通信业务量、该第一装置的资源需求、或该第一装置的信道质量中的至少一个。那么第二装置可以根据或参考上述获知的信息为第一装置确定第四时频资源。
步骤S616:第一装置接收来自该第二装置针对所述资源占用信息的确认信息,则第一装置继续通过该第二时频资源进行域内通信,流程结束。或者,第一装置接收来自第二装置的资源重配信息,则继续执行步骤S618;
步骤S618:第一装置根据所述资源重配信息,通过第五时频资源向至少一个第三装置 发送第三信息。
具体地,第一装置在接收到资源重配信息后,解析该资源重配信息,获知指示的第四时频资源。然后从该第四时频资源中确定出第五时频资源,其中该第五时频资源为该第四时频资源的子集。也就是说,第一装置从第四时频资源中选取一部分时频资源,用于第一通信域内的通信。然后,第一装置可以向至少一个第三装置发送资源变更信息,该资源变更信息用于指示该第五时频资源的信息。也就是说,通过该资源变更信息,第一装置可以向该至少一个第三装置指示时频同步调整、变更的资源(变更为第五时频资源)以及资源变更时间等。
其中,该第三信息是本申请资源重配后第一装置发送给至少一个第三装置的信息,该第二信息是本申请资源重配之前第一装置发送给至少一个第三装置的信息。该第三同步信号用于在本申请资源重配后该第三装置与以该第一装置为主节点的通信域的同步;而该第一同步信号用于在本申请资源重配之前该第三装置与以该第一装置为主节点的通信域的同步。该第三信息包含的业务数据、控制信息或者系统信息是申请资源重配后的数据或信息;而该第二信息包含的业务数据、控制信息或者系统信息是申请资源重配之前的数据或信息。
在一种可能的实现方式中,该资源变更信息可以是第五时频资源的配置信息,或者是与第五时频资源有关的时域和/或频域的信号,例如载波号等。本申请实施例不作限制,只要第三装置接收到该资源变更信息,能从该资源变更信息中获知指示的第五时频资源即可。
其中,本申请实施例中的第四时频资源与目标时频资源不交叠,第四时频资源也可以与第一时频资源不交叠。本申请实施例中的第四时频资源也可以与目标时频资源交叠。
在资源变更完成或资源切换完成之后,第一装置即可通过第五时频资源向至少一个第三装置发送第三信息,也就是说实现了通过第五时频资源进行第一通信域的通信。
其中,该第三信息可以包含第三同步信号,以及,参考信号、业务数据、控制信息或者系统信息中的至少一个。
实施例二,第一信息承载于广播消息:
如图7示出本申请提供的另一实施例的通信方法的流程示意图,可以包括如下步骤:
步骤S700:第二装置发送广播消息;
具体地,本申请各个实施例中第二装置广播发送的广播消息可以包括系统信息。该广播消息对应于第一时频资源,或者说第一信息承载于该广播消息。该第一信息用于指示第一时频资源,即该第二同步信号可以携带有指示信息,以指示该第一时频资源。
在一种可能的实现方式中,在广播消息中指示第一时频资源的时域或频域信息,如指示帧号、超帧号、信道号或者子信道号等中的至少一个;其中,该帧或超帧的结构,比如帧或超帧的时长、帧或超帧的信道排布等,可以由通信双方进行协商配置,或由协议规定。
例如,超帧的时长为1毫秒。进一步可选的,每个超帧包括48个无线帧,当无线帧的帧号为0、2、4等偶数时,第一符号为下行(以SD表示),当帧号为1、3、5等奇数时(以SU表示),第一符号为上行。那么在一个超帧内,可以包括24个SD和24个SU。
另一种可能的实现方式中,在广播消息中指示第一时频资源的位置是几种可能位置中的哪一种。例如,两种第一时频资源的位置是编号为基数的时间单元和编号为偶数的时间 单元。在广播消息中可以通过预设标识来指示第一时频资源的位置是哪一种,例如该预设标识0指示第一时频资源的位置是编号为基数的时间单元;该预设标识1指示第一时频资源的位置是编号为偶数的时间单元。
其中,在步骤S700之前,第二装置可以确定了目标时频资源,第二装置通过该目标时频资源与至少一个第四装置进行通信。该目标时频资源与该第一时频资源不交叠。

步骤S704:第一装置根据该广播消息,确定第二时频资源;
具体地,第一装置可以解析该广播消息,获知指示的第一时频资源。然后从该第一时频资源中确定出第二时频资源,其中该第二时频资源为该第一时频资源的子集。也就是说,第一装置从第一时频资源中确定一部分时频资源,用于第一通信域内的通信。

在一种可能的实现方式中,本实施例步骤S710至步骤S718可以替换为图6实施例的步骤S610至步骤S618。
实施例三,第一信息承载于第二同步信号和广播消息:

步骤S800:第二装置发送第二同步信号和广播消息;
具体地,本申请实施例可以通过第二同步信号和广播消息共同指示第一时频资源的信息,即第一信息承载于第二同步信号和广播消息。例如,第二同步信号中的一部分信息,与广播消息中的一部分信息组合得到用于指示第一时频资源的信息,即第一信息。
在一种可能的实现方式中,在协议中预设了多组第一时频资源可能的位置,每组中有多个第一时频资源的位置。那么通过第二同步信号和广播消息共同指示第一时频资源的信息时,可以具体通过第二同步信号的循环移位量或标识来指示第一时频资源的位置在预设的多组中的哪一组,然后在广播消息中指示第一时频资源的位置是该组中的哪一个。即,第二同步信号的循环移位量或标识用于指示所述第一时频资源所属的组标识,所述广播消息用于指示所述第一时频资源在其所属的组中的子标识、位置或者索引等信息。

如图11示出本申请提供的另一实施例的通信方法的流程示意图,可以包括如下步骤:
步骤S1100:第二装置发送第一组播消息和第一单播消息;
具体地,本申请实施例可以通过第一组播消息和第一单播消息共同指示第一时频资源的信息,即第一信息承载于第一组播消息和第一单播消息。例如,第一组播消息中的一部分信息,与第一单播消息中的一部分信息组合得到用于指示第一时频资源的信息,即第一信息。

在一种可能的实现方式中,第一装置与该第二装置建立了通信连接之后,在步骤S1100之前还可以包括第一装置向第二装置发送资源请求信息;该资源请求信息用于请求时频资源。那么第二装置接收到该资源请求信息后,确定第一时频资源,然后执行步骤S1100。

步骤S1106:第一装置向至少一个第三装置发送资源变更信息;

具体地,步骤S1106至步骤S1108可以对应参考图9实施例中步骤S906至步骤S908的描述,这里不再赘述。
本申请实施例用于指示第一时频资源的信息承载于第二装置发送的第一组播消息和第一单播消息中,那么第一装置在检测到第二装置发送的该第一组播消息和该第一单播消息即可获知指示的第一时频资源,从而实现或建立起来的域间通信资源协调机制,能够避免资源冲突,解决了现有技术在中高负载下不同通信链路使用的资源重叠的概率仍然较高,通信链路间互相干扰较为严重的技术问题。
基于以上所有可能的实施例,在一种可能的实现方式中,第一时频资源在时域上不连续。
具体地,本申请实施例,该第一时频资源并非一段时域上连续的时频资源。例如:该第一时频资源仅包含编号为奇数的帧(或超帧),那么第一装置使用第二时频资源(第一时频资源的子集)进行通信域内的通信时,可以在编号为偶数的帧(或超帧)与第二装置进行通信。又如第一时频资源包括的帧的编号可以为多组编号,每组内的编号可以为连续或不连续,每组之间的编号不连续,例如第一组包括编号为1、2、3,第二组包括编号为7、8,等等。第一装置使用的第二时频资源在时域上也不连续。
同样地,本申请各个实施例中的第四时频资源也可以在时域上不连续。
当第一装置和第二装置同时作为主节点时,若它们的收发时间相同,那么第一装置将无法接收到第二装置发射的信号和信息,无法完成与第二装置同步、系统信息接收、发射资源请求、获取第二装置对第一装置所在通信域的资源调度信息等操作。本申请实施例通过规定第一时频资源或第四时频资源在时域上不连续,能够解决上述技术问题。第一装置可以在该第一时频资源或第四时频资源所属时域以外的时域上完成与第二装置同步、系统信息接收、发射资源请求、获取第二装置对第一装置所在通信域的资源调度信息等操作,也就是说错开了第一装置与第二装置交互,第一装置与所在通信域的其他装置交互的时间。
在一种可能的实现方式中,第一时频资源、或第二时频资源、或第四时频资源、或第五时频资源的确定方式可以包括如下方式:
1、由通信协议规定。即通信双方可以根据通信协议获知到具体的时频资源,那么本申 请各个实施例中的第一信息可以只是一个特定标识或预设标识,通信双方都知晓该特定标识或预设标识的作用或含义。即第二装置发送该特定标识或预设标识,为了指示第一装置根据通信协议规定的时频资源进行域内通信。第一装置接收到该特定标识或预设标识,即获知需要根据通信协议规定的时频资源进行域内通信。
2、第二装置确定并分配时频资源。即第二装置发送的第一信息含有确定出的时频资源信息,第一装置通过解析该第一信息来获知到第二装置确定并分配的时频资源。
其中,第二装置会为不同的目标通信域分配不同的时频资源。第二装置会根据当前目标通信域已占有或使用的时频资源,确定其他不交叠的时频资源分配给新的目标通信域。例如当前目标通信域(第一装置为主节点的通信域)是根据第一时频资源中的第二时频资源来进行域内通信,那么第二装置在为其他目标通信域分配时频资源时,将会根据第一时频资源和第二时频资源确定出第六时频资源,从而给其他通信域分配该第六时频资源。该第六时频资源既与第二时频资源不交叠,与第一资源不交叠,也与目标时频资源不交叠。
3、由第二装置发射的第二同步信号中的时、频、码等信息中的至少一种来确定出时频资源。其中确定的方法或算法可以由通信协议规定。该第二同步信号可以包括主同步信号和/或辅同步信号。
可以理解的,上述提供的两种连接方式是两种示例性的连接方式,实际应用中两个电子设备之间的连接不限于上述两种连接方式。
