附图说明
为了更清楚地说明本发明实施例的技术方案，下面将对本发明实施例中所需要使用的附图作简单地介绍，显而易见地，下面所描述的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1是适用本发明实施例的设备间通信的方法的通信系统的一例的示意性图。
图2是本发明实施例的设备间通信的方法的一例的示意性流程图。
图3是本发明实施例的设备间通信的装置的一例的示意性框图。
图4是本发明实施例的设备间通信的设备的一例的示意性结构图。
具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
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。
本发明的各个方面或特征可以实现成方法、装置或使用标准编程和/或工程技术的制品。本申请中使用的术语“制品”涵盖可从任何计算机可读器件、 载体或介质访问的计算机程序。例如，计算机可读介质可以包括，但不限于:磁存储器件(例如，硬盘、软盘或磁带等)，光盘(例如，CD(Compact Disk，压缩盘)、DVD(Digital Versatile Disk，数字通用盘)等)，智能卡和闪存器件(例如，EPROM(Erasable Programmable Read-Only Memory，可擦写可编程只读存储器)、卡、棒或钥匙驱动器等)。另外，本文描述的各种存储介质可代表用于存储信息的一个或多个设备和/或其它机器可读介质。术语“机器可读介质”可包括但不限于，无线信道和能够存储、包含和/或承载指令和/或数据的各种其它介质。
本发明实施例的方案可以应用于现有的蜂窝通信系统，如全球移动通讯(英文全称可以为：Global System for Mobile Communication，英文简称可以为：GSM)，宽带码分多址(英文全称可以为：Wideband Code Division Multiple Access，英文简称可以为：WCDMA)，长期演进(英文全称可以为：Long Term Evolution，英文简称可以为：LTE)等系统中，所支持的通信主要是针对语音和数据通信的。通常来说，一个传统基站支持的连接数有限，也易于实现。
下一代移动通信系统将不仅支持传统的通信，还将支持M2M(英文全称可以为：Machine to Machine)通信，或者叫做MTC(英文全称可以为：Machine Type Communication)通信。根据预测，到2020年，连接在网络上的MTC设备将会达到500到1000亿，这将远超现在的连接数。对M2M类业务，由于其业务种类千差万别，对网络需求存在很大差异。大致来说，会存在如下几种需求：
可靠传输，但对时延不敏感；
低延迟，高可靠传输。
对可靠传输，而对时延不敏感业务，较容易处理。但是，对低延迟、高可靠传输类的业务，不仅要求传输时延短，而且要求可靠，比如V2V(英文全称为：Vehicle to Vehicle)业务或V2X(英文全称为：Vehicle to Everything)业务。如果传输不可靠，会导致重传而造成传输时延过大，不能满足要求。根据本发明实施例的方案能够有效解决传输的可靠性问题。
可选地，该终端设备为用户设备。
本发明结合终端设备描述了各个实施例。终端设备也可以称为用户设备(UE，User Equipment)、移动台、接入终端、用户单元、用户站、移动站、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理 或用户装置等。终端设备可以是WLAN(Wireless Local Area Networks，无线局域网)中的ST(STAION，站点)，可以是蜂窝电话、无绳电话、SIP(Session Initiation Protocol，会话启动协议)电话、WLL(Wireless Local Loop，无线本地环路)站、PDA(Personal Digital Assistant，个人数字处理)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备以及未来5G网络中的移动台或者未来演进的PLMN网络中的终端设备等。
此外，在本发明实施例中，终端设备还可以包括中继(Relay)等，其他能够和接入网设备(例如，基站)进行数据通信的设备。
另外，在本发明实施例中，接入网设备可以是用于与移动台通信的设备，接入网设备可以是WLAN(Wireless Local Area Networks，无线局域网)中的AP(ACCESS POINT，接入点)，GSM或CDMA(Code Division Multiple Access，码分多址)中的BTS(Base Transceiver Station，基站)，也可以是WCDMA中的NB(NodeB，基站)，还可以是LTE(Long Term Evolution，长期演进)中的eNB或eNodeB(Evolutional Node B，演进型基站)，或者中继站或接入点，或者车载设备、可穿戴设备以及未来5G网络中的接入网设备或者未来演进的PLMN网络中的接入网设备等。
图1是适用本发明实施例的用于设备间通信的方法和装置的通信系统100的示意图。如图1所示，该通信系统100包括至少两个终端设备，例如图1中的终端设备110和终端设备120，其中，终端设备110和终端设备120可以是例如蜂窝电话、智能电话、便携式电脑、手持通信设备、手持计算设备、卫星无线电装置、全球定位系统、PDA和/或用于在无线通信系统100上通信的任意其它适合设备。
在给定时间，终端设备110和终端设备120可以是无线通信发送装置和/或无线通信接收装置。当发送数据时，无线通信发送装置可对数据进行编码以用于传输。具体地，无线通信发送装置可获取(例如生成、从其它通信装置接收、或在存储器中保存等)要通过信道发送至无线通信接收装置的一定数目的数据比特。这种数据比特可包含在数据的传输块(或多个传输块)中，传输块可被分段以产生多个码块。
应理解，以上列举的通信系统100包括的终端设备的数量仅为示例性说明，本发明并未限定于此，通信系统100所包括的终端设备的数量可以为大 于1的任意整数。
此外，该通信系统100可以是公共陆地移动网络(英文全称可以为：Public Land Mobile Network，英文简称可以为：PLMN)网络或者D2D网络或者M2M网络或者V2V网络或者V2X网络或者其他网络，图1只是举例的简化示意图，网络中还可以包括其他网络设备，图1中未予以画出。例如，通信系统100还可以包括接入网设备(图1中未示出)。
其中，接入网设备可包括多个天线。另外，接入网设备可附加地包括发射机链和接收机链，本领域普通技术人员可以理解，它们均可包括与信号发送和接收相关的多个部件(例如处理器、调制器、复用器、解调器、解复用器或天线等)。
接入网设备可以与多个终端设备(例如终端设备110和终端设备120)通信。然而，可以理解，接入网设备可以与类似于终端设备110或120的任意数目的终端设备通信。
并且，接入网设备可以配置有多个天线，并且，例如，接入网设备可以通过一个天线，基于前向链路向终端设备110发送信息，并通过反向链路从终端设备110接收信息。并且，接入网设备还可以通过另一个天线，基于前向链路向终端设备120发送信息，并通过反向链路从终端设备120接收信息
例如，在频分双工(FDD，Frequency Division Duplex)系统中，同一终端设备所使用的前向链路和反向链路可以使用不同频带。
再例如，在时分双工(TDD，Time Division Duplex)系统和全双工(Full Duplex)系统中，同一终端设备所使用的前向链路和反向链路可使用共同频带。
其中，接入网设备被设计用于通信的每个天线(或者由多个天线组成的天线组)和/或区域称为接入网设备的扇区。例如，可将天线组设计为与接入网设备覆盖区域的扇区中的终端设备通信。在接入网设备通过前向链路分别与终端设备进行通信的过程中，接入网设备的发射天线可利用波束成形来改善前向链路的信噪比。此外，与接入网设备通过单个天线向它所有的终端设备发送信号的方式相比，在接入网设备利用波束成形向相关覆盖区域中随机分散的终端设备发送信号时，相邻小区中的移动设备会受到较少的干扰。
在给定时间，接入网设备可以是无线通信发送装置和/或无线通信接收装置。当发送数据时，无线通信发送装置可对数据进行编码以用于传输。具体 地，无线通信发送装置可获取(例如生成、从其它通信装置接收、或在存储器中保存等)要通过信道发送至无线通信接收装置的一定数目的数据比特。这种数据比特可包含在数据的传输块(或多个传输块)中，传输块可被分段以产生多个码块。
下面，对本发明实施例中设备间通信所使用的频域资源进行说明。
可选地，在本发明实施例中，终端设备能够使用免授权频谱资源(或者说，免许可频段)进行设备间通信，即，本发明实施例的通信系统100是能够使用免授权频段的通信系统，作为示例而非限定，该通信系统100可以采用免授权载波上的长期演进系统LAA-LTE(Licensed-Assisted Access Using LTE)技术，或者，也可以采用支持该通信系统在免授权频段独立部署的技术例如Standalone LTE over unlicensed spectrum，或者，也可以采用LTE-U(LTE-U，LTE Advanced in Unlicensed Spectrums)技术，例如，通信系统100可以将LTE系统独立部署到免授权频段，进而在免授权频段上采用LTE空口协议完成通信，该系统不包括授权频段。部署在免授权频段的LTE系统可以利用集中调度、干扰协调、自适应请求重传(HARQ)等技术，相对于Wi-Fi等接入技术，该技术具有更好的鲁棒性，可以获得更高的频谱效率，提供更大的覆盖范围以及更好的用户体验。
免授权频谱资源是指无需系统分配，各个通信设备可以共享使用免许可频谱包括的资源。免许可频段上的资源共享是指对特定频谱的使用只规定发射功率、带外泄露等指标上的限制，以保证共同使用该频段的多个设备之间满足基本的共存要求，运营商利用免许可频段资源可以达到网络容量分流的目的，但是需要遵从不同的地域和不同的频谱对免许可频段资源的法规要求。这些要求通常是为保护雷达等公共系统，以及保证多系统尽可能互相之间不造成有害影响、公平共存而制定的，包括发射功率限制、带外泄露指标、室内外使用限制，以及有的地域还有一些附加的共存策略等。例如，各通信设备能够采用竞争方式或者监听方式，例如，先听后说(LBT，Listen Before Talk)规定的方式使用的频谱资源。
作为示例而非限定，在本发明实施例中，该免授权频谱资源可以包括5GHz附近的约900MHz的频段，2.4GHz频段附近约90MHz的频段。
此外，在本发明实施例中，终端设备还可以使用授权频谱资源进行设备间通信，即，本发明实施例的通信系统100是能够使用授权频段的通信系统。
授权频谱资源一般需要国家或者地方无线委员会审批才可以使用的频谱资源，不同系统例如LTE系统与WiFi系统，或者，不同运营商包括的系统不可以共享使用授权频谱资源。
图2示出了本发明一实施例的设备间通信的方法200的示意性流程图。如图2所示，该方法200包括：
S210，第一终端设备获取第一时频资源，该第一时频资源是用于传输第一业务的数据的时频资源，该第一业务属于设备间通信业务；
S220，该第一终端设备根据该第一时频资源，发送第二业务的数据，该第二业务属于设备间通信业务。
具体地说，在S210，终端设备A(即，第一终端设备的一例)可以产生业务A(即，第一业务的一例)，并且，终端设备A可以在时刻A获取用于传输该业务A的数据的时频资源A(即，第一时频资源的一例)。
作为示例而非限定，例如，在本发明实施例中，终端设备A可以基于接入网设备(例如，基站)的调度获取该时频资源A，并且，此情况下，该时频资源A可以是该接收网设备从所使用的授权频谱资源或免授权频谱资源中确定的，本发明并未特别限定。并且，终端设备A基于接入网设备的调度获取该时频资源A的具体过程和方法可以与现有技术中终端设备基于接入网设备的调度获取用于进行设备间通信的时频资源的具体过程和方法相似，这里，为了避免赘述，省略其详细说明。
或者，在本发明实施例中，终端设备A可以自主确定该时频资源A，例如，终端设备A可以采用例如，竞争方式或者监听等方式确定该时频资源A，并且，此情况下，该时频资源A可以是属于通信系统提供的供多个终端设备通过竞争等方式使用的授权频谱资源或免授权频谱资源，本发明并未特别限定。并且，终端设备A自主确定该时频资源A的具体过程和方法可以与现有技术中终端设备自主确定用于进行设备间通信的时频资源的具体过程和方法相似，这里，为了避免赘述，省略其详细说明。
在S220，当终端设备A在时刻B(位于时刻A之后)产生业务B(即，第二业务的一例)时，该终端设备A可以通过该时频资源A传输该业务B的数据。
从而，该终端设备A无需进行获取用于传输该业务B的数据的时频资源B(即，第二时频资源的一例)的过程，从而，能够减小该业务B的传输 时延。
作为示例而非限定，在本发明实施例中，还可以预先设置一个或多个预设条件，终端设备A可以根据该业务B、业务A以及时频资源A等参数，确定该预设条件是否得到满足，并在确定该预设条件满足后，通过该时频资源A传输该业务B的数据。
作为示例而非限定，在本发明实施例中，作为预设条件可以列举一下至少一种条件：
条件A
可选地，在该第一终端设备根据该第一时频资源，发送第二业务的数据之前，该方法还包括：
该第一终端设备确定该第二业务的优先级高于该第一业务的优先级；或者
该第一终端设备确定该第二业务的紧急程度高于该第一业务的的紧急程度；或者
该第一终端设备确定该第二业务的业务类型属于预设的第一业务类型集合，其中，该第一业务类型集合包括至少一种业务类型。
具体地说，在该终端设备A在通过该时频资源A传输该业务B的数据之前，该终端设备A还可以确定该业务B的传输是否能够优先于业务A的传输。
作为示例而非限定，例如，终端设备A可以根据该业务B和该业务A的优先级，确定该业务B的传输是否能够优先于业务A的传输。例如，在本发明实施例中，终端设备A可以获取用于指示各业务的优先级的信息(以下，为了便于理解和说明，记做：优先级信息)，作为示例而非限定，该终端设备A可以从网络设备(例如，基站等接入网设备)获取该优先级信息；或者，该优先级信息可以由制造商在该终端设备A出厂时配置在该终端设备A中；再或者，该优先级信息可以由用户输入至该终端设备A中。从而，该终端设备A可以根据该优先级信息，确定业务B和该业务A的优先级，并且，如果业务B的优先级高于该业务A的优先级，则该终端设备A可以确定该业务B的传输优先于业务A的传输，进而，该终端设备A可以通过该时频资源A传输该业务B的数据。并且，作为示例而非限定，在本发明实施例中，该优先级信息可以指示多种业务类型集合与多种优先级之间的第一 对应关系，其中，每个业务类型集合包括至少一种业务类型，从而，终端设备A可以根据该业务A的业务类型，确定该业务A所属于的业务类型集合，进而确定该业务A的优先级，类似地，终端设备A可以根据该业务B的业务类型，确定该业务B所属于的业务类型集合，进而确定该业务B的优先级。或者，在本发明实施例中，该优先级信息可以指示多种业务标识集合与多种优先级之间的第一对应关系，其中，每个业务标识集合包括至少一种业务标识，从而，终端设备A可以根据该业务A的业务标识，确定该业务A所属于的业务标识集合，进而确定该业务A的优先级，类似地，终端设备A可以根据该业务B的业务标识，确定该业务B所属于的业务标识集合，进而确定该业务B的优先级。另外，作为示例而非限定，按照优先级从高到低的顺序，本发明实施例的优先级可以依次为：高级、一般和低级。
再例如，终端设备A可以根据该业务B和该业务A的紧急程度，确定该业务B的传输是否能够优先于业务A的传输。例如，在本发明实施例中，终端设备A可以获取用于指示各业务的紧急程度的信息(以下，为了便于理解和说明，记做：紧急程度信息)，作为示例而非限定，该终端设备A可以从网络设备(例如，基站等接入网设备)获取该紧急程度信息；或者，该紧急程度信息可以由制造商在该终端设备A出厂时配置在该终端设备A中；再或者，该紧急程度信息可以由用户输入至该终端设备A中。从而，该终端设备A可以根据该紧急程度信息，确定业务B和该业务A的紧急程度，并且，如果业务B的紧急程度高于该业务A的紧急程度，则该终端设备A可以确定该业务B的传输优先于业务A的传输，进而，该终端设备A可以通过该时频资源A传输该业务B的数据。并且，作为示例而非限定，在本发明实施例中，该紧急程度信息可以指示多种业务类型集合与多种紧急程度之间的第一对应关系，其中，每个业务类型集合包括至少一种业务类型，从而，终端设备A可以根据该业务A的业务类型，确定该业务A所属于的业务类型集合，进而确定该业务A的紧急程度，类似地，终端设备A可以根据该业务B的业务类型，确定该业务B所属于的业务类型集合，进而确定该业务B的紧急程度。或者，在本发明实施例中，该紧急程度信息可以指示多种业务标识集合与多种紧急程度之间的第一对应关系，其中，每个业务标识集合包括至少一种业务标识，从而，终端设备A可以根据该业务A的业务标识，确定该业务A所属于的业务标识集合，进而确定该业务A的紧急程度， 类似地，终端设备A可以根据该业务B的业务标识，确定该业务B所属于的业务标识集合，进而确定该业务B的紧急程度。另外，作为示例而非限定，按照紧急程度从高到低的顺序，本发明实施例的紧急程度可以依次为：紧急和非紧急。
再例如，终端设备A可以根据该业务B的业务类型，确定该业务B的传输是否能够优先于业务A的传输。例如，在本发明实施例中，终端设备A可以获取用于指示能够优先传输的业务的业务类型的信息(以下，为了便于理解和说明，记做：业务类型信息)，作为示例而非限定，该终端设备A可以从网络设备(例如，基站等接入网设备)获取该业务类型信息；或者，该业务类型信息可以由制造商在该终端设备A出厂时配置在该终端设备A中；再或者，业务类型信息可以由用户输入至该终端设备A中。从而，该终端设备A可以根据该业务类型信息确定能够优先传输的(一个或多个)业务的业务类型(即，第一业务类型集合的一例)，如果业务B的业务类型属于能够优先传输的业务的业务类型，则该终端设备A可以确定该业务B的传输优先于业务A的传输，进而，该终端设备A可以通过该时频资源A传输该业务B的数据。
条件B
可选地，在该第一终端设备根据该第一时频资源，发送第二业务的数据之前，该方法还包括：
该第一终端设备确定第二时频资源的大小，该第二时频资源是传输该第二业务的数据所需要的最小的时频资源；
该第一终端设备确定该第一时频资源的大小大于或等于该第二时频资源的大小
具体地说，在本发明实施例中，终端设备A可以确定传输该业务B的数据所需要的最小的时频资源(例如，时频资源B)的大小，并且，如果时频资源A的大小大于或等于时频资源B的大小，或者说，如果时频资源A的大小能够满足该业务B的数据的最低传输要求，则该终端设备A可以通过该时频资源A传输该业务B的数据。
作为示例而非限定，在本发明实施例中，终端设备A可以根据业务B的服务质量(QoS，Quality of Service要求，确定该业务B所能允许的最高的调制编码方式(MCS，Modulation and Coding Scheme)，进而确定传输该 业务B的数据所需要的最小的时频资源。
条件C
可选地，在该第一终端设备根据该第一时频资源，发送第二业务的数据之前，该方法还包括：
该第一终端设备确定该第一业务的传输方式为半静态传输，其中，该第一时频资源具体是该第一业务的下一传输周期所对应的时频资源。
具体地说，在基于调度确定时频资源的方式中，随着通信技术的发展，已经能够提供多种设备间通信业务的调度方式，例如，动态调度，静态调度和半静态调度等。
其中，半静态调度(即，半静态传输的一例)也可以称为半持续调度，即，接入网设备可以为终端设备分配一定的通信时长范围(或者是，半静态传输的有效时间范围)，在该半静态传输的有效时间范围内终端设备可以按照一定的周期(也可以称为：工作周期(Duty Cycle))使用接入网设备分配的频域资源，从而，接入网设备可以通过一次资源调度，通知终端设备在该半静态传输的有效时间范围内所使用的频域资源，并在该半静态传输的有效时间范围内无需再通过调度信令指示该频域资源。与动态调度相比，这种调度方式灵活性稍差，但控制信令开销较小，适合突发特征不明显、有保障速率要求的业务，例如网络语音(VoIP，Voice over Internet Protocol)业务或长期演进语音(VoLTE，Voice over Long Term Evolution)业务等。
类似地，对于采用竞争方式或监听方式等确定时频资源的情况下，终端设备可以竞争一定的通信时长范围(或者是，半静态传输的有效时间范围，例如，一次突发传输所对应的时长范围，或者，一次传输机会所对应的时长范围)，在该半静态传输的有效时间范围内，终端设备可以按照一定的周期使用所竞争到的频域资源，从而，终端设备可以通过一次竞争，获取在该半静态传输的有效时间范围内所使用的频域资源，并在该半静态传输的有效时间范围内无需再次竞争或监听频域资源。
设终端设备A判定是否使用该业务A的时频资源传输业务B的数据的时刻为时刻C(即，当前时刻的一例，作为示例而非限定，该时刻C与时刻B可以是同一时刻)，此情况下，该时频资源A可以是该业务A的在时刻C之后的第一个传输周期(即，业务A的下一传输周期(例如，下一Duty Cycle)，或者说，业务A的下一传输时段)所对应的时频资源。
作为示例而非限定，设业务A的相邻的两个传输周期(或者说传输时段)为周期A和周期B，如果该时刻C处于该周期A和周期B之间(具体地说，是周期A的起始时刻之后至周期B的起始时刻之前的时段)，则“业务A的下一传输周期”可以是指周期B。
从而，如果该业务A的传输方式为半静态传输，则终端设备A可以确定该业务A的数据可能有多个传输周期，即，时频资源A所对应的时间范围以外，还可能有多个用于传输业务A的时间范围，从而，终端设备A可以确定，占用该时频资源A对该业务A的传输的影响较小，从而，能够进一步改善用户体验，提高传输的可靠性。
条件D
可选地，在该第一终端设备根据该第一时频资源，发送第二业务的数据之前，该方法还包括：
该第一终端设备发起第一判定处理，以确定第一时长小于或等于预设的第一阈值，该第一时长是发起第一判定处理的时刻距离该第一时频资源在时域上的起始时刻的时长。
具体地说，终端设备A可以进行判定是否使用该业务A的时频资源传输业务B的数据的处理(即，第一判定处理的一例)，并且，终端设备A可以记录该第一判定处理的起始时刻(例如，上述时刻C，作为示例而非限定，该时刻C与时刻B可以是同一时刻)。
设上述时刻C与时频资源A的起始时刻之间的时长为时长A(即，第一时长的一例)，则在上述条件C的基础上，终端设备A还可以进一步确定该时长A是否小于或等于预设的时间阈值#1(即，第一阈值的一例)。并在判定为“是”的情况下，终端设备A可以确定使用时频资源A传输业务B的数据。
作为示例而非限定，该时间阈值#1可以是基于终端设备A从发起获取时频资源(例如，上述时频资源B)的处理到确定时频资源的时长，例如，该时间阈值#1可以是终端设备A该向基站发起资源调度请求至接收并解析到基站所分配的时频资源的时长，或者，该时间阈值#1也可以是终端设备A发起竞争或监听至确定时频资源的时长。
另外，在本发明实施例中，该时间阈值#1可以根据实验获得，并由制造商在该终端设备A出厂时，预设在该终端设备A中，或者，该时间阈值#1 也可以由用户输入至终端设备A，本发明并未特别限定。
并且，作为示例而非限定，该时间阈值#1可以是具体的某种时长，也可以是包括多种时长的时长范围，本发明并未特比限定，另外，作为示例而非限定，该时间阈值#1可以为例如，10毫秒(ms)。
从而，如果时长A小于或等于预设的时间阈值#1，则表明通过时频资源A传输业务B的数据的时延小于通过上述时频资源B传输业务B的数据的时延，从而，能够进一步提高本发明的效果。
条件E
可选地，在该第一终端设备根据该第一时频资源，发送第二业务的数据之前，该方法还包括：
该第一终端设备发起第一判定处理，以确定第一时长大于或等于预设的第二阈值，该第一时长是发起第一判定处理的时刻距离该第一时频资源的起始时刻的时长；
该第一终端设备发起用于获取第三时频资源的处理；
该第一终端设备发起第二判定处理，以确定第二时长大于或等于预设的第三阈值，该第二时长是该第一终端设备发起用于获取第三时频资源的处理的时刻至发起第二判定处理的时刻所经历的时长，该第三时频资源是用于传输该第二业务的数据的时频资源。
具体地说，终端设备A可以进行判定是否使用该业务A的时频资源传输业务B的数据的处理(即，第一判定处理的一例)，并且，终端设备A可以记录该第一判定处理的起始时刻(例如，上述时刻C，作为示例而非限定，该时刻C与时刻B可以是同一时刻)。
设上述时刻C与时频资源A的起始时刻之间的时长为时长A(即，第一时长的一例)，则在上述条件C的基础上，终端设备A还可以进一步确定该时长A是否小于或等于预设的时间阈值#2(即，第一阈值的一例)。
作为示例而非限定，该时间阈值#2可以是基于终端设备A从发起获取时频资源(例如，上述时频资源B)的处理到确定时频资源的时长，例如，该时间阈值#2可以是终端设备A该向基站发起资源调度请求至接收并解析到基站所分配的时频资源的时长，或者，该时间阈值#2也可以是终端设备A发起竞争或监听至确定时频资源的时长。
另外，在本发明实施例中，该时间阈值#2可以根据实验获得，并由制造 商在该终端设备A出厂时，预设在该终端设备A中，或者，该时间阈值#2也可以由用户输入至终端设备A，本发明并未特别限定。
并且，作为示例而非限定，该时间阈值#2可以是具体的某种时长，也可以是包括多种时长的时长范围，本发明并未特比限定，另外，作为示例而非限定，该时间阈值#2可以为例如，10毫秒(ms)。
需要说明的是，在本发明实施例中，该时间阈值#2与时间阈值#1可以相同，或者，时间阈值#2也可以大于时间阈值#1，本发明并未特别限定。
从而，当时长A大于或等于预设的时间阈值#2时，该第一判定处理的结果表明使用时频资源A传输业务B的数据的时延可能大于获取新的用于传输业务B的数据的时延，从而，终端设备A可以发起获取时频资源B的处理。并且，终端设备A可以记录发起获取时频资源B的处理的时刻(记做，时刻D)。
终端设备A可以在时频资源A的起始时刻之前再次判定是否使用该业务A的时频资源传输业务B的数据(即，第二判定处理的一例)，并且，终端设备A可以确定该时刻D至该第二判定处理的起始时刻起所经历的时长B(即，第二时长的一例)。
终端设备A还可以进一步判定时长B是否大于或等于预设的时间阈值#3(即，第三阈值的一例)。并在判定为“是”的情况下，终端设备A可以确定使用时频资源A传输业务B的数据。
作为示例而非限定，该时间阈值#3可以是基于终端设备A从发起获取时频资源(例如，上述时频资源B)的处理到确定时频资源的时长，例如，该时间阈值#3可以是终端设备A该向基站发起资源调度请求至接收并解析到基站所分配的时频资源的时长，或者，该时间阈值#3也可以是终端设备A发起竞争或监听至确定时频资源的时长。
从而，如果时长B大于或等于预设的时间阈值#3，则表明终端设备B可能无法获取时频资源B，从而，通过时频资源A传输业务B的数据的时延仍然可能小于通过上述时频资源B传输业务B的数据的时延，从而，能够进一步提高本发明的效果。
需要说明的是，在本发明实施例中，时间阈值#3可以小于时间阈值#2，从而，能够确保终端设备A在决定使用时频资源A传输业务B的数据的时刻尚未到达时频资源A的起始时刻，进而，能够确保基于时频资源A传输 业务B的数据的可靠性。
条件F
当该第二业务的传输方式为半静态传输时，在该第一终端设备根据该第一时频资源，发送第二业务的数据之前，该方法还包括：
该第一终端设备确定该第二业务的传输周期是该第一业务的传输周期的整数倍。
具体地说，在本发明实施例中，如果业务A为的传输方式为半静态传输，并且，业务B为的传输方式为半静态传输，则终端设备A可以判定业务B的传输周期是否为业务A的传输周期的整数倍，并在判定为“是”的情况下，终端设备A可以确定使用时频资源A传输业务B的数据。作为示例而非限定，例如，如果业务A的传输周期为X毫秒，X＞0，则当业务B的传输周期为K·X毫秒时，终端设备A可以确定使用时频资源A传输业务B的数据，其中，K为大于0的整数。
从而，能够确保能够使用业务A的时频资源完整地传输业务B的数据。作为示例而非限定，例如，如果业务A的周期(或者说，业务A的相邻的两个传输时段之间的时间间隔)是10ms，业务B的周期(或者说，业务B的相邻的两个传输时段之间的时间间隔)是20ms，在业务A的总的传输时长范围包括业务B的总的传输时长范围的情况下，业务B的每个传输时段上的数据均能够通过业务A的时频资源传输。再例如，如果业务B的周期(或者说，业务A的相邻的两个传输时段之间的时间间隔)是5ms，业务A的周期(或者说，业务B的相邻的两个传输时段之间的时间间隔)是10ms，则业务B的部分传输时段上的数据不能通过业务A的时频资源传输，例如，设业务A和业务B的第一个周期的起始时刻重合，则业务B的偶数的传输时段上的数据不能通过业务A的时频资源传输。
应理解，以上列举的各判定条件仅为示例性说明，本发明并未限定于此，并且，上述各条件可以单独使用也可以结合使用，本发明并未特别限定。
在本发明实施例中，可能同时存在多个第一业务，即，除业务A以外，可能存在其他的在时刻B之前已经获得传输资源的业务，以下，为了便于理解和说明，以业务C为例，对除业务A以外的第一业务进行说明。即，在时刻B之前，终端设备A已经获取用于传输业务C的数据的时频资源(即，第一时频资源的另一例，以下，为了便于理解和区分，记做：时频资源C)。
并且，可选地，终端设备A还可以判定业务C是否满足上述条件A～条件E中的一个或多个。
从而，当终端设备A判定时频资源A和时频资源C均可以用于传输业务B的数据时。终端设备A还可以从时频资源A和时频资源C选择一个时频资源(即，目标第一业务所对应的第一时频资源的一例)，来传输业务B的数据。
作为示例而非限定，终端设备A可以根据各第一业务(例如，业务A和业务C)所对应的第一时频资源(例如，时频资源A和时频资源C)的起始时刻，来确定目标第一业务，以及目标第一业务的第一时频资源。例如，终端设备A可以记录进行上述选择的时刻(记做：时刻F)，则如上所述，各第一时频资源的起始时刻均处于时刻F之后，并且，终端设备A可以将起始时刻距离该时刻F最近的第一时频资源所对应的第一业务，作为目标第一业务。
例如，设(满足上述条件A～条件E中的一个或多个条件的)第一业务包括业务A和业务C，如果时频资源A的起始时刻在时频资源C的起始时刻之前(其中，时频资源C的起始时刻以及时频资源A的起始时刻均处于时刻F之后)，则终端设备A可以将业务A作为目标第一业务，即，终端设备A可以确定使用时频资源A传输业务B的数据。
在终端设备A通过时频资源A传输业务B的数据之后，终端设备A还可以对本应在该时频资源A上传输的业务A的数据(以下，为了便于理解和区分，记做：数据A)进行进一步处理。
例如，可选地，该通信单元还用于丢弃需要在该第一时频资源上传输的该第一业务的数据。
具体地说，终端设备A可以丢弃该数据A。
或者，可选地，该获取单元还用于获取第四时频资源，该第四时频资源所对应的时间在第一半静态传输时间范围以外，该第一半静态传输时间范围是用于传输该第一业务的数据的时间范围，该第一半静态传输时间范围包括该第一时频资源所对应的时间；
该通信单元还用于通过该第四时频资源发送该第一业务的数据。
具体地说，在本发明实施例中，由于上述时频资源A被用于传输业务B的数据，因此导致数据A没有被传输，此情况下，终端设备A可以将数据A 延后一个周期发送，并且，业务A的在传输顺序(时间顺序)上位于该数据A之后的数据可以依次延后一个周期。
此情况下，如果终端设备A获取的用于传输业务A的数据的时频资源的大小仅能够满足业务A的数据量，由于上述时频资源A被用于传输业务B的数据，可能导致所获取的用于传输业务A的数据的时频资源不足以传输业务A的数据，进而，导致没有时频资源可以承载业务A的在传输顺序上位于末尾的数据(以下，为了便于理解和区分，记做：数据B)。
对此，终端设备A可以例如，在业务A的半静态传输的有效时间范围内，发起获取用于传输该数据B的时频资源的过程，并且，如果在业务A的半静态传输的有效时间范围内，能够获取用于传输该数据B的时频资源，则终端设备A可以通过所获取的时频资源，传输该数据B；如果在业务A的半静态传输的有效时间范围内，不能获取用于传输该数据B的时频资源，则终端设备A可以丢弃该数据B。
应理解，以上列举的对数据A和数据B的处理方式仅为示例性说明，本发明并未限定于此，例如，终端设备A还可以正常发送业务A的数据中除该数据A以外的数据(例如，数据B)，并且，终端设备A可以例如，在业务A的半静态传输的有效时间范围内，发起获取用于传输该数据A的时频资源的过程，并且，如果在业务A的半静态传输的有效时间范围内，能够获取用于传输该数据A的时频资源，则终端设备A可以通过所获取的时频资源，传输该数据A；如果在业务A的半静态传输的有效时间范围内，不能获取用于传输该数据A的时频资源，则终端设备A可以丢弃该数据A。
需要说明的是，在本发明实施例中，上述业务A所需要发送至的终端设备与业务B所需要发送至的终端设备可以相同也可以不同，本发明并未特别限定。
并且，在本发明实施例中，终端设备A(即，第一终端设备的一例)可以采用广播发送方式，发送业务A(即，第一业务的一例)的数据以及业务B(即，第二业务的一例)的数据。
从而，由于采用广播方式，能够确保业务B所需要发送至的终端设备能够检测到该时频资源A，进而从该时频资源A中获取业务B的数据。
根据本发明实施例的设备间通信的方法，通过使第一终端设备时域已获取的用于传输第一业务的数据的第一时频资源，发送第二业务的数据，例如， 在第二业务对传输时延要求较高的情况下，终端设备可以无需发起获取用于传输该第二业务的时频资源，能够缩短该第二业务的传输时延，进而，能提高设备间通信的灵活性和可靠性。
