Description

通信方法、装置及系统、计算机存储介质 技术领域
本申请涉及无线通信技术领域，特别涉及一种通信方法、装置及系统、计算机存储介质，尤其适用于短距离无线通信，例如座舱域通信。
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。例如，车载通信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、长度和重量，以及与之对应的安装、维护和保养成本，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和类型都越来越多，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，多个通信节点之间以通信域的方式实现通信。在一定通信区域或范围内可能存在一个或多个通信域。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)，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。主节点管理的时频资源包括接入请求资源、调度请求资源、和用于其它控制信令和/或业务数据传输的资源。接入请求资源用于不属于通信域的节点(可以简称为外部节点)向通信域的主节点发送接入请求，接入请求用于请求发起该外部节点加入该通信域的过程；调度请求资源用于从节点向主节点发送调度请求(scheduling request，SR)，该调度请求用于向主节点请求分配资源，该资源用于主节点和从节点之间的控制信令和/或业务数据的传输。通常主节点为从节点分配各自的调度请求资源。
但是，由于外部节点发送接入请求的频度以及从节点发送调度请求的频度通常均较低，因此目前接入请求资源和调度请求资源的利用率通常较低，导致时频资源的总体利用率较低。
发明内容
本申请提供了一种通信方法、装置及系统、计算机存储介质，可以解决相关技术中时频资源的总体利用率较低的问题。
第一方面，提供了一种通信方法。该方法包括：目标设备确定第一时频子资源，该第一时频子资源属于第一时频资源。目标设备在第一时频子资源上发送第一请求，该第一请求用于请求接入或者请求调度。其中，第一时频资源是预先定义或者预先配置的、用于承载该目标设备的请求的资源。目标设备的请求包含用于请求接入的请求和用于请求调度的请求。目标设备为外部节点或通信域中的从节点。本申请中，将用于请求接入的请求称为接入请求，用于请求调度的请求称为调度请求。其中，外部节点指当前不属于通信域的设备，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。
可替代地，上述方法包括：目标设备确定第一时频子资源，该第一时频子资源属于第一 时频资源。目标设备在第一时频子资源上发送接入请求或调度请求。其中，第一时频资源是预先定义或者预先配置的、用于承载至少一个目标设备的接入请求和调度请求的资源。本申请中，接入请求用于外部节点请求加入主节点所在的通信域的过程(即用于请求接入)。调度请求用于从节点向主节点请求分配资源(即用于请求调度)，该资源用于主节点和从节点之间的控制信令和/或业务数据的传输。目标设备发送接入请求和调度请求时与该通信域的关系不同。例如：目标设备发送接入请求时不属于该通信域，对于该通信域是外部节点；目标设备发送调度请求时是该通信域的从节点。
本申请中，由于目标设备发送接入请求和/或调度请求时，复用第一时频资源，与目标设备使用不同时频资源发送接入请求和调度请求相比，提高了时频资源的利用率，也无需分别对接入请求和调度请求的资源进行配置或者定义。
可选地，第一时频资源用于承载多个目标设备的请求。也即是，多个目标设备可以在第一时频资源上发送接入请求和/或调度请求。
本申请中，多个目标设备发送接入请求和/或调度请求时，复用第一时频资源，与目标设备使用不同时频资源发送接入请求和调度请求、不同目标设备使用不同时频资源发送调度请求相比，可以提高时频资源的利用率，也无需分别对接入请求和每个目标设备对应的调度请求的资源进行配置或者定义。
可选地，第一请求用于请求接入(即第一请求为接入请求)，则第一请求包含第一标识。上述方法还包括：目标设备在第二时频子资源上发送第二请求，该第二请求用于请求调度(即第二请求为调度请求)。该第二时频子资源属于第一时频资源，该第二请求包含第二标识，该第二标识不同于第一标识。其中，第一标识用于指示发送第一请求的设备为通信系统中的外部节点，且该第一请求为接入请求，或者说，第一标识用于指示外部节点请求接入主节点或者接入主节点所在的通信域。第二标识用于指示发送第二请求的设备为通信域中的从节点，且该第二标识在该通信域中唯一标识发送该第二请求的设备。
本申请中，通信系统预留一个或多个保留标识，该保留标识不同于第二标识，但第一标识一定是一个保留标识，以保证第二标识和第一标识不同。根据请求中包含的标识是否为保留标识，可以区分请求的类型是否为接入请求。并且，若第一请求为调度请求，由于第二标识在通信域中唯一标识发送该调度请求的设备，通信域中的主节点根据调度请求中包含的第二标识，可以确定发送该调度请求的设备。可选地，该一个或者多个保留标识可以为预先定义的，例如标准或者协议定义，或者预先配置的，例如主节点预先配置的。
可选地，第一请求用于请求接入，第一请求包含第一标识。上述方法还包括：目标设备接收广播消息，该广播消息中包含一个或多个保留标识的信息，该第一标识属于一个或多个保留标识。
其中，第一时频资源可以是预先定义或预先配置的。第一时频资源是预先定义的，包括：第一时频资源由标准或者协议定义。第一时频资源是预先配置的，包括：第一时频资源由通信域中的主节点预先通过广播消息配置。可选地，第一时频资源是预先配置的。上述方法还包括：目标设备接收广播消息，该广播消息中包括第一时频资源的配置信息。
本申请中，通过在标准或者协议中预先定义第一时频资源，实现机制简单。或者，通过主节点预先配置第一时频资源，灵活性高且应用场景较丰富。
可选地，上述广播消息为系统消息。
本申请中，当保留标识和第一时频资源均由主节点配置时，主节点可以将一个或多个保留标识的信息与第一时频资源的配置信息承载于一个广播消息中发送；或者，主节点可以将一个或多个保留标识的信息承载于一个广播消息中发送，将第一时频资源的配置信息承载于另一个广播消息中发送，也即是主节点采用两个广播消息分别承载保留标识的信息和第一时频资源的配置信息。本申请对此不做限定。
可选地，第一请求用于请求接入。上述方法还包括：目标设备接收目标消息，该目标消息中包含第二标识的信息，该第二标识承载于第二请求中，该第二请求用于请求调度。该第二标识用于在通信域中唯一标识目标设备。
可选地，目标消息为接入响应(即对接入请求的响应)，该接入响应是通过第二时频资源接收的，第二时频资源基于第一时频子资源确定。
本申请中，目标设备在第一时频子资源上发送接入请求，可以根据第一时频子资源确定用于接收接入响应的第二时频资源。可选地，标准或协议中预先定义、或者主节点预先配置第一时频资源中的每个时频子资源对应的应答资源。目标设备可以根据标准或协议中的定义，或者主节点的配置，确定与第一时频子资源对应的应答资源为第二时频资源。
可选地，第一请求用于请求调度(即第一请求为调度请求)。上述方法还包括：目标设备通过第三时频资源接收调度响应，该调度响应中包括第四时频资源的配置信息，该第四时频资源用于传输业务数据和/或控制信息。调度响应中可以包括第二标识。该第二标识用于指示该调度响应为针对目标设备发送的调度请求的响应。
可选地，第三时频资源基于第一时频子资源确定，或者，第三时频资源基于第一时频子资源以及第一请求的调度类型确定。由于不同调度类型的调度响应所需要的处理时间和传输该调度响应需要的资源量可能不同，因此需要传输不同调度类型的调度响应的应答资源也不同，从而本申请中第三时频资源可以基于第一时频子资源以及第一请求的调度类型确定。
本申请中，目标设备在第一时频子资源上发送调度请求，可以根据第一时频子资源确定用于接收调度响应的第三时频资源。可选地，标准或协议中预先定义、或者主节点预先配置第一时频资源中的每个时频子资源对应的应答资源。目标设备可以根据标准或协议中的定义，或者主节点的配置，确定与第一时频子资源对应的应答资源为第三时频资源。
第二方面，提供了一种通信方法。该方法包括：第一设备在第一时频子资源上接收第一请求，该第一请求用于请求接入或者请求调度，第一时频子资源属于第一时频资源。其中，第一时频资源是预先定义或者预先配置的、用于承载目标设备的请求的资源，目标设备的请求包含用于请求接入的请求和用于请求调度的请求。第一设备为通信域中的主节点，目标设备为外部节点或该通信域中的从节点。
可选地，第一设备在第二时频子资源上接收第二请求，该第二请求用于请求接入或者请求调度，第二时频子资源属于第一时频资源。第一请求和第二请求可以来自不同的设备。也即是，第一时频资源可以用于承载多个目标设备的请求。
可选地，第一请求用于请求接入，第一请求包含第一标识。上述方法还包括：第一设备在第二时频子资源上接收第二请求，该第二请求用于请求调度，第二时频子资源属于第一时频资源，第二请求包含第二标识，第二标识不同于第一标识。第一设备根据第二请求中的第二标识，确定发送该第二请求的设备为通信域中的从节点。
可选地，第一请求用于请求接入，第一请求包含第一标识。上述方法还包括：第一设备 发送广播消息，该广播消息中包含一个或多个保留标识的信息，第一标识属于一个或多个保留标识。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
本申请实施例提供了一种通信系统，该通信系统包括一个或多个通信域。每个通信域中包括一个主通信节点(简称：主节点)以及一个或多个从通信节点(简称：从节点)。通信域中的每个从节点分别与主节点建立通信链路。其中，一个通信域中的从节点可作为另一个通信域中的主节点。可选地，通信系统中还包括外部节点。外部节点指未加入通信系统中的任一通信域的节点，也即是，外部节点未与通信系统中的任一通信域中的主节点建立通信链路，即外部节点当前不属于通信域。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。主节点管理的时频资源包括接入请求资源、调度请求资源、和用于其它控制信令和/或业务数据传输的资源。接入请求资源用于外部节点向通信域的主节点发送接入请求，接入请求用于请求发起该外部节点加入该通信域的过程。调度请求资源用于从节点向主节点发送调度请求，该调度请求用于向主节点请求分配资源，该资源用于主节点和从节点之间的控制信令和/或业务数据的传输。
可选地，图1是本申请实施例提供的一种通信系统的结构示意图。如图1所示，该通信系统包括第一设备110、第二设备120A-120B(统称为第二设备120)以及第三设备130A-130B(统称为第三设备130)。第一设备110为通信域中的主节点，第二设备120为该通信域中的从节点，第三设备130为外部节点。图1中第二设备和第三设备的数量仅用作示例，不作为对本申请实施例提供的通信系统的限制。例如，第三设备的数量也可以为0，即通信系统中不包括第三设备。
可选地，本申请实施例提供的通信系统可以应用于车载网络、无线局域网(wireless local  area network，WLAN)或蜂窝网络等无线网络。当该通信系统应用于车载网络时，第一设备110可以是座舱域控制器(cockpit domain controller，CDC)，第二设备120和第三设备130可以是麦克风、音箱或手机等终端；或者，第一设备110可以是无钥匙进入及启动系统(passive entry passive start，PEPS)，第二设备120和第三设备130可以是手机钥匙或车钥匙等；又或者，第一设备110可以是手机，第二设备120和第三设备130可以是耳机或可穿戴设备等。当该通信系统应用于WLAN时，第一设备110可以是接入点(access point，AP)，第二设备120和第三设备130可以是站点(station，STA)。当该通信系统应用于蜂窝网络时，第一设备110可以是基站，第二设备和第三设备可以是用户设备(user equipment，UE)。
本申请实施例以该通信系统应用于车载网络为例进行说明。示例地，图2是本申请实施例提供的另一种通信系统的结构示意图。如图2所示，该通信系统中包括三个通信域C1-C3。
通信域C1中包括CDC 101、麦克风102、音箱103和手机104。其中，CDC 101为主节点，麦克风102、音箱103和手机104均为从节点。麦克风102、音箱103和手机104分别与CDC 101无线连接。CDC 101还可以与车载系统的显示屏有线连接。
通信域C2中包括PEPS 105、手机钥匙106和车钥匙107。其中，PEPS 105为主节点，手机钥匙106和车钥匙107均为从节点。手机钥匙106和车钥匙107分别与PEPS 105无线连接。PEPS 105还可以与车身控制器(body control module，BCM)有线连接。
通信域C3中包括手机104、耳机108和可穿戴设备109。其中，手机104为主节点，耳机108和可穿戴设备109均为从节点。耳机108和可穿戴设备109分别与手机104无线连接。
在如图2所示的通信系统中，手机104既是通信域C1中的从节点，又是通信域C3中的主节点。
对于车载网络而言，外部节点向主节点发送接入请求的频度较低，从节点向主节点发送调度请求的频度也较低。外部节点向主节点发送接入请求的场景包括：当手机钥匙或车钥匙靠近或进入车辆时，会向PEPS发送接入请求；当车辆内的音箱或麦克风等设备被人为打开或手机欲接入CDC时，会向CDC发送接入请求。由于这些事件的发生频度均较低，因此车载网络中外部节点向主节点发送接入请求的频度较低。从节点向主节点发送调度请求的场景包括：当从节点需发起新业务或发起半静态调度(semi-persistent scheduling，SPS)业务变更时，会向主节点发送调度请求。车载网络中的业务包括主要业务和少量突发业务。主要业务的业务量比较稳定，一般使用SPS方式调度，无需频繁发起新业务。突发业务发生时间随机，一般使用动态调度，由于突发业务的业务量很少，也不会导致频繁发起新业务。因此从节点因需发起新业务而触发发送调度请求的频度较低。SPS业务变更一般由业务量变更或由于信道条件变化导致的调制编码策略(modulation and coding scheme，MCS)变更引起。由于车内节点之间距离较短且相对运动较慢，因此车载网络中的无线信道具有频域平坦和时域变换慢的特征，即信道条件相对稳定。因此从节点因需发起SPS业务变更而触发发送调度请求的频度较低。
目前，分配有一组时频资源供外部节点发送接入请求，且每个从节点分别分配有一组时频资源供对应的从节点发送调度请求，即用于承载接入请求和调度请求的时频资源不同，且用于承载不同从节点发送的调度请求的时频资源也不同。由于外部节点发送接入请求的频度以及从节点发送调度请求的频度均较低，因此目前时频资源的总体利用率较低。而在本申请实施例提供的通信方法中，采用同一组时频资源承载用于请求接入的请求(即接入请求)和 用于请求调度的请求(即调度请求)，由于接入请求和调度请求承载于同一组时频资源，因此提高了时频资源的利用率。另外本申请实施例中，多个设备可以共用同一组时频资源发送调度请求，进一步提高了时频资源的利用率。
图3是本申请实施例提供的一种通信方法的流程示意图。该方法可以应用于如图1或图2所示的通信系统。如图3所示，该方法包括：
步骤301、目标设备确定第一时频子资源。
该第一时频子资源属于第一时频资源。其中，第一时频资源是预先定义或者预先配置的、用于承载目标设备的请求的资源。目标设备的请求包含用于请求接入的请求和用于请求调度的请求。需要说明的是，本申请实施例所提到的第一时频资源不用于传输业务数据，并非目标设备可用的全部资源。本申请实施例中，将用于请求接入的请求称为接入请求，将用于请求调度的请求称为调度请求。可选地，目标设备为通信系统中的从节点或外部节点。例如，目标设备可以为如图1所示的通信系统中的第二设备120或第三设备130。
第一时频资源是预先定义的，包括：第一时频资源由标准或者协议定义。第一时频资源是预先配置的，包括：第一时频资源由第一设备预先通过广播消息配置。第一设备为通信系统中的主节点。例如，第一设备可以为如图1所示的通信系统中的第一设备110。第一时频资源是用于承载目标设备的请求的资源，也即是，第一时频资源用于承载目标设备的接入请求和调度请求。该接入请求用于请求接入第一设备，该调度请求用于向第一设备请求调度请求资源，该调度请求资源用于目标设备传输业务数据和/或控制信息。
可选地，第一时频资源由第一设备预先配置。第一设备在通信系统中发送广播消息，例如第一设备可以在通信系统中周期性地发送广播消息，该广播消息中包括第一时频资源的配置信息。目标设备在接收到广播消息之后，在第一时频资源中确定第一时频子资源。第一时频资源包括一个或多个时频子资源。可选地，当第一时频资源包括多个时频子资源时，目标设备可以将第一时频资源中的任一时频子资源确定为第一时频子资源，也即是，第一时频子资源可以是第一时频资源中的任一时频资源。或者，目标设备可以将第一时频资源中的第一个时频子资源确定为第一时频子资源，也即是，第一时频子资源可以是第一时频资源中的第一个时频子资源，本申请实施例对在第一时频资源中确定第一时频子资源的方式不做限定。可选地，该广播消息为系统消息。
第一时频资源的配置信息包括该第一时频资源中各个时频子资源的时域信息和频域信息。本申请实施例中，一个时频子资源对应在时域上可以是一个正交频分复用(orthogonal frequency division multiplexing，OFDM)符号，对应在频域上可以是一个子载波，也即是，一个时频子资源可以由一个OFDM符号和一个子载波组成。时频资源通常为周期性资源，第一时频资源中的时频子资源可以由一个周期内的第i个OFDM符号和第j个子载波组成，i和j均为正整数，i小于或等于一个周期内OFDM符号的总数，j小于或等于一个周期内子载波的总数。可选地，第一时频资源的配置信息为{(i 1,j 1)；(i 2,j 2)；…；(i n,j n)}，表示第一时频资源中包括n个时频子资源，i n表示第n个时频子资源对应在时域上为第i n个OFDM符号，j n表示第n个时频子资源对应在频域上为第j n个子载波，n为正整数，且n小于或等于一个周期内OFDM符号的总数与一个周期内子载波的总数的乘积。示例地，图4是本申请实施例提供的第一时频资源的示意图。其中横坐标表示时域，纵坐标表示频域，每个时频子资源对应一 个小方块。如图4所示，总时频资源包括矩阵状排布的多个时频子资源，第一时频资源包括其中的多个时频子资源。
本申请实施例中，通过在标准或者协议中预先定义第一时频资源，实现机制简单。或者，通过主节点预先配置第一时频资源，灵活性高且应用场景较丰富。
可选地，第一时频资源用于承载多个目标设备的请求。该多个目标设备可以位于通信系统的同一通信域中，也可以位于通信系统的不同通信域中。本申请实施例中，多个目标设备发送接入请求和/或调度请求时复用第一时频资源，与目标设备分别使用不同时频资源发送接入请求和调度请求、不同目标设备使用不同时频资源发送调度请求相比，可以提高时频资源的利用率，也无需分别对接入请求和每个目标设备对应的调度请求的资源进行配置或者定义。
可选地，第一时频资源还可以用于承载除接入请求和调度请求以外的其它请求，例如用于请求获取系统信息的请求或用于请求获取信道信息的请求等，本申请实施例对此不做限定。
步骤302、目标设备在第一时频子资源上发送第一请求。
相应地，第一设备在第一时频子资源上接收第一请求。第一设备在接收到第一请求后，可以确定该第一请求的请求类型、发送该第一请求的节点或节点类型等信息中的至少一种。该第一请求用于请求接入或者请求调度。也即是，该第一请求为接入请求或者调度请求。当目标设备为通信系统中的外部节点时，第一请求为接入请求，用于请求接入第一设备，也即是，该第一请求用于请求与第一设备建立通信链路。当目标设备为第一设备所在通信域中的从节点时，第一请求为调度请求，用于向第一设备请求调度请求资源。该调度请求资源为用于传输业务数据和/或控制信息的时频资源。其中，控制信息包括但不限于业务变更指令、MCS变更指令、调度信令和信道质量指示信息。
本申请实施例中，由于目标设备发送接入请求和/或调度请求时复用第一时频资源，与目标设备使用不同时频资源发送接入请求和调度请求相比，提高了时频资源的利用率，也无需分别对接入请求和调度请求的资源进行配置或者定义。
可选地，接入请求包含第一标识(identity，ID)。调度请求包含第二标识。第二标识不同于第一标识。第一标识用于指示发送请求的设备为通信系统中的外部节点，且该请求为接入请求，或者说，第一标识用于指示外部节点请求接入主节点或者接入主节点所在的通信域。第二标识用于指示发送请求的设备为通信域中的从节点，且第二标识在该通信域中唯一标识发送该请求的设备。
在本申请实施例中，通信系统预留一个或多个保留标识，该保留标识不同于第二标识，但第一标识一定是一个保留标识，以保证第二标识和第一标识不同。根据请求中包含的标识是否为保留标识，可以区分请求的类型是否为接入请求。并且，若第一请求为调度请求，由于第二标识在通信域中唯一标识发送该调度请求的设备，第一设备(即通信域中的主节点)根据调度请求中包含的第二标识，可以确定发送该调度请求的设备。
保留标识和第二标识可以均由第一设备分配，例如第一设备预先配置一个或多个保留标识。或者，保留标识可以由标准或者协议定义，第二标识由第一设备分配。当保留标识由标准或者协议定义时，外部节点获取标准或者协议定义的一个或多个保留标识中的一个保留标识，并将该保留标识作为第一标识承载于接入请求中。
示例地，本申请实施例提供的保留标识和第二标识可以如表1所示，其中，n为正整数，m为大于n的整数。
表1
Figure PCTCN2020080820-appb-000001
参见表1，第一设备或协议预留有n个保留标识，分别为ID1至IDn。第一设备为(m-n)个接入第一设备的从节点分别分配一个第二标识，分别为IDn+1至IDm。第二标识可以是从节点的MAC地址，或者，第二标识可以由第一设备确定，例如可以是字母、数字、字符及其组合等，用于在第一设备所在的通信域中唯一标识一个设备。
可选地，保留标识由第一设备分配。第一设备在通信系统中发送广播消息，例如第一设备可以在通信系统中周期性地发送广播消息，该广播消息中包括一个或多个保留标识的信息。其中，保留标识的信息可以是保留标识，也可以是保留标识的指示信息，通过该指示信息能够获取保留标识。目标设备在接收到广播消息之后，从该一个或多个保留标识中获取一个保留标识作为第一标识，也即是，第一标识属于该一个或多个保留标识。
可选地，该广播消息为系统消息。本申请实施例中，广播消息指采用广播方式发送的消息。系统消息是一种采用广播方式发送且包含系统配置的消息，也即是，系统消息是一种广播消息。该广播消息还可以是除系统消息外其它采用广播方式发送的消息，本申请实施例对此不做限定。
本申请实施例中，当保留标识和第一时频资源的配置信息均由第一设备分配时，第一设备可以将一个或多个保留标识的信息与第一时频资源的配置信息承载于一个广播消息中发送；或者，第一设备可以将一个或多个保留标识的信息承载于一个广播消息中发送，将第一时频资源的配置信息承载于另一个广播消息中发送，也即是第一设备采用两个广播消息分别承载保留标识的信息和第一时频资源的配置信息。本申请实施例对此不做限定。
第一设备为每一个接入该第一设备的目标设备分别分配一个第二标识。可选地，第一设备在接收到目标设备发送的接入请求后，可以向目标设备发送目标消息，该目标消息中包括第二标识的信息。可选地，第一设备可以在目标设备接入该第一设备(即目标设备加入第一设备为主节点的通信域)的过程中为目标设备分配第二标识。该目标消息可以为对接入请求的响应(即接入响应)。或者，该目标消息也可以不为接入响应。第一设备在接收到目标设备发送的接入请求后，可以回复一个仅用于承载第二标识的信息的目标消息，例如，第一设备在确定目标设备成功接入第一设备之后，向该目标设备发送承载第二标识的目标消息。
本申请实施例中，各种类型的信息均承载于消息中传输。例如，第一时频资源的配置信息承载于广播消息中传输，保留标识的信息承载于广播消息中传输，第一设备为从节点分配的第二标识的信息承载于目标消息中传输。本申请实施例涉及的上述消息可以包括协议数据单元(protocol data unit，PDU)的包头和/或数据字段，也即是，该消息可以是仅包括数据字 段的数据包，该消息也可以是PDU包头，还可以包括PDU包头和数据字段。上述消息也可以是承载了信息的信号，例如该消息可以是时域的序列构成的信号，通过序列的循环移位指示信号所承载的信息。本申请实施例对消息的类型不做限定。
可选地，本申请提供了以下两个可选实施例，分别以上述目标设备为通信系统中的外部节点和从节点为例，对上述通信方法的实现过程进行说明。
在本申请的第一个可选实施例中，目标设备为通信系统中的外部节点，第一请求为接入请求。图5是本申请实施例提供的另一种通信方法的流程示意图。应用该方法的通信系统至少包括设备1和设备2，其中，设备1为主节点，设备2为外部节点。举例来说，设备1可以是如图1所示的通信系统中的第一设备110，设备2可以是如图1所示的通信系统中的第三设备130。该方法具体可以用于实现如图3对应实施例所示的方法，例如设备1可以是第一设备，设备2可以是目标设备。如图5所示，该方法包括：
步骤501、设备2确定第一时频子资源。
第一时频子资源属于第一时频资源。设备2确定第一时频子资源的过程可参考上述步骤301中目标设备确定第一时频子资源的过程，本申请实施例在此不再赘述。
步骤502、设备2在第一时频子资源上发送接入请求。
可选地，接入请求包含第一标识。该第一标识用于指示设备2为外部节点并指示发送的请求的请求类型为接入请求。
本申请实施例中，设备1在第一时频资源的各个时频子资源上尝试接收请求。设备2在第一时频子资源上发送接入请求，则设备1可以在第一时频子资源上接收到该接入请求。可选地，第一时频子资源为第一时频资源中的任一时频子资源。设备2采用竞争的方式在第一时频子资源上发送接入请求，即设备2首先尝试在第一时频子资源上发送接入请求，若设备2在第一时频子资源上没有成功发送接入请求，例如设备2确定第一时频子资源繁忙或者设备2接入设备1失败，则设备2在第一时频资源中确定新的时频子资源重新尝试发送接入请求。可选地，确定新的时频子资源的方式为随机选择退避时长，并选择退避时长之后的一个时频子资源(例如第一个时频子资源)。由于目前通信系统中的设备发起接入请求和调度请求的频度均较低，因此设备2在第一时频子资源上发送接入请求时与其它设备发送的接入请求或调度请求冲突的概率较低，进而设备在第一时频资源中的时频子资源上成功发送请求的可能性较高，即使在冲突的情况下，设备2仍可以通过一次或多次的确定新的发送接入请求的时频子资源，完成接入请求的发送。
步骤503、设备1在第二时频资源上发送接入响应。
可选地，第二时频资源基于第一时频子资源确定。设备1在第一时频子资源上接收到设备2发送的接入请求后，可以根据第一时频子资源确定用于发送接入响应的第二时频资源。本申请实施例中，可以在标准或协议中预先定义、或者由主节点预先配置第一时频资源中的每个时频子资源对应的应答资源，设备1在第一时频子资源上接收到接入请求后，可以根据标准或协议中的定义，或者主节点的配置，确定与第一时频子资源对应的应答资源为第二时频资源。另外，设备2在第一时频子资源上发送接入请求，也可以根据相同的规则(设备1采用的规则)确定与第一时频子资源对应的第二时频资源，并在第二时频资源上尝试接收接入响应。在标准或协议中预先定义、或者由主节点预先配置第一时频资源中的每个时频子资源对应的应答资源的方式可对应参考上述在标准或协议中预先定义、或者由主节点预先配置 第一时频资源的方式，本申请实施例在此不再赘述。
可选地，接入响应中包含第二标识。
步骤504、设备2确定第二时频子资源。
第二时频子资源属于第一时频资源。第二时频子资源与第一时频子资源可以相同，也可以不同。设备2确定第二时频子资源的过程可参考上述步骤301中目标设备确定第一时频子资源的过程，本申请实施例在此不再赘述。
步骤505、设备2在第二时频子资源上发送调度请求。
该调度请求用于向设备1请求用于传输业务数据和/或控制信息的时频资源。可选地，调度请求包含第二标识。该第二标识用于指示设备2为设备1的从节点，且该第二标识用于在设备1和设备2所在的通信域中唯一标识设备2。
本申请实施例中，设备1在第一时频资源的各个时频子资源上尝试接收请求。设备2在第二时频子资源上发送调度请求，则设备1可以在第二时频子资源上接收到该接入请求。可选地，第二时频子资源为第一时频资源中的任一时频子资源。设备2采用竞争的方式在第二时频子资源上发送调度请求。设备2采用竞争的方式在第二时频子资源上发送调度请求的过程可参考步骤502中设备2采用竞争的方式在第一时频子资源上发送接入请求的过程，本申请实施例在此不再赘述。
步骤506、设备1在第三时频资源上发送调度响应。
调度响应中包括第四时频资源的配置信息，该第四时频资源用于传输业务数据和/或控制信息。对第四时频资源的配置信息的解释可参考步骤301中对第一时频资源的配置信息的解释，本申请实施例在此不再赘述。可选地，调度响应中还包括第二标识。由于设备1可能会接收到多个设备发送的接入请求和/或调度请求，通过在调度响应中携带第二标识，可以指示该响应是对调度请求的响应以及具体是对哪个设备发送的调度请求的响应。例如，该调度响应中携带设备2对应的第二标识，则可以指示该调度响应为对设备2发送的调度请求的响应。
可选地，第三时频资源基于第二时频子资源确定，或者，第三时频资源基于第二时频子资源以及调度请求的类型确定。调度请求的类型用于指示该调度请求所请求的调度请求资源需要传输的具体内容。例如，调度请求的类型用于指示传输业务数据或控制信息；或者，调度请求的类型用于指示传输的控制信息的具体类型，包括但不限于业务变更指令、MCS变更指令、调度信令或信道质量指示信息。
在一种实现方式中，第三时频资源基于第二时频子资源确定。设备1在第二时频子资源上接收到设备2发送的调度请求后，根据第二时频子资源确定用于发送调度响应的第三时频资源。本申请实施例中，可以在标准或协议中预先定义、或者由主节点预先配置第一时频资源中的每个时频子资源对应的应答资源，设备1在第二时频子资源上接收到调度请求后，可以根据标准或协议中的定义，或者主节点的配置，确定与第二时频子资源对应的应答资源为第三时频资源。另外，设备2在第二时频子资源上发送调度请求，也可以根据相同的规则(设备1采用的规则)确定与第二时频子资源对应的第三时频资源，并在第三时频资源上尝试接收调度响应。在标准或协议中预先定义、或者由主节点预先配置第一时频资源中的每个时频子资源对应的应答资源的方式可对应参考上述在标准或协议中预先定义、或者由主节点预先配置第一时频资源的方式，本申请实施例在此不再赘述。
在另一种实现方式中，第三时频资源基于第二时频子资源以及调度请求的调度类型确定。 由于不同调度类型的调度响应所需要的处理时间和传输该调度响应需要的资源量可能不同，因此需要传输不同调度类型的调度响应的应答资源也不同，从而本申请实施例中第三时频资源可以基于第二时频子资源以及调度请求的调度类型确定。设备1在第二时频子资源上接收到设备2发送的调度请求后，根据第二时频子资源以及调度请求的类型确定用于发送调度响应的第三时频资源。本申请实施例中，可以在标准或协议中预先定义、或者由主节点预先配置第一时频资源中的每个时频子资源对应的应答资源。其中，一个时频子资源对应一个或多个应答资源。当一个时频子资源对应多个应答资源时，还可以在标准或协议中预先定义、或者由主节点预先配置每个应答资源对应的请求类型，例如应答资源1对应接入请求，应答资源2对应调度请求1，应答资源3对应调度请求2，调度请求1和调度请求2的类型不同。设备1在第二时频子资源上接收到调度请求后，可以根据标准或协议中的定义，或者主节点的配置，确定与第二时频子资源以及该调度请求的类型对应的应答资源为第三时频资源。另外，设备2在第二时频子资源上发送调度请求，也可以根据相同的规则(设备1采用的规则)确定与第二时频子资源对应的第三时频资源，并在第三时频资源上尝试接收调度响应。
在本申请实施例中，多个设备向通信域中的主节点发送接入请求和/或调度请求时，竞争性地使用同一时频资源中的时频子资源，与分别使用不同时频资源发送接入请求和调度请求、不同设备分别使用不同时频资源发送调度请求相比，提高了时频资源的利用率。另外，无需为接入请求和调度请求分别设计不同的时频资源，简化了通信机制。
在本申请的第二个可选实施例中，目标设备为通信系统中的从节点，第一请求为调度请求。图6是本申请实施例提供的又一种通信方法的流程示意图。应用该方法的通信系统至少包括设备3和设备4，其中，设备3为主节点，设备4为从节点。举例来说，设备3可以是如图1所示的通信系统中的第一设备110，设备4可以是如图1所示的通信系统中的第二设备120。或者。设备3可以是如图2所示的通信系统中的CDC 101，设备4可以是如图2所示的通信系统中的麦克风102。该方法具体可以用于实现如图3对应实施例所示的方法，例如设备3可以是第一设备，设备4可以是目标设备。如图6所示，该方法包括：
步骤601、设备4确定第一时频子资源。
设备2确定第一时频子资源的过程可参考上述步骤301中目标设备确定第一时频子资源的过程，本申请实施例在此不再赘述。
步骤602、设备4在第一时频子资源上发送调度请求。
此步骤的解释可参考上述步骤505的解释，本申请实施例在此不再赘述。
步骤603、设备3在第三时频资源上发送调度响应。
此步骤的解释可参考上述步骤506的解释，本申请实施例在此不再赘述。
综上所述，本申请实施例提供的通信方法，采用同一时频资源承载一个或多个设备的接入请求和调度请求。由于设备发送接入请求和/或调度请求时复用同一时频资源，与设备使用不同时频资源发送接入请求和调度请求相比，提高了时频资源的利用率。多个设备复用同一时频资源发送调度请求，与不同设备分别使用不同时频资源发送调度请求相比，提高了时频资源的利用率。另外，多个设备竞争性地使用同一时频资源中的时频子资源，无需为接入请求和每个设备对应的调度请求分别设计不同的时频资源，简化了通信机制。
图7是本申请实施例提供的一种通信装置的结构示意图。该装置可以应用于如图1所示 的通信系统中的第二设备120或第三设备130，或者，该装置也可以是第二设备120或者第三设备130中的芯片或者集成电路。如图7所示，该装置70包括：
