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。

图1是根据本申请实施例的应用场景100的示意性图。在图1中，UE102、UE103、UE104在基站101的覆盖范围下，UE102、UE103和UE104可以与基站直接通信，UE102、UE103和UE104之间进行D2D通信；UE105和UE106不在基站的覆盖范围下，UE105和UE106之间可以直接进行D2D通信，或者与UE102、UE103和UE104之间进行D2D通信。
D2D技术本身的短距离通信特点和直接通信方式使其具有如下优势：
1.终端近距离直接通信方式可实现较高的数据速率、较低的延迟和较低的功耗；
2.利用网络中广泛分布的终端以及D2D通信链路的短距离特点，可以实现频谱资源的有效利用，获得资源空分复用增益；
3.D2D的直接通信方式能够适应如无线P2P等业务的本地数据共享需求，提供具有灵活适应能力的数据服务；
4.D2D直接通信能够利用网络中数量庞大且分布广泛的通信终端以拓展网络的覆盖范围。
在混合蜂窝与D2D网络下，终端可以以两种不同的模式通信。其一，蜂窝通信模式：终端通过基站进行通信；其二，D2D模式：终端使用D2D链路直接通信。在该混合网络中，部分终端仍以蜂窝通信模式通过基站进行信息转发和通信，部分终端则以终端直通模式进行数据的直接传输。
D2D不仅用于公共安全业务，也可以广泛的应用与商用场景中，用以解决覆盖延伸、设备省电等现实问题。例如，通过终端中继技术可以实现覆盖 增强，蜂窝网络覆盖之外的终端可以通过中继实现与网络的数据通信，一定意义上实现了网络覆盖的延伸。另外，采用类似短距通信可以节省终端的发送功率，有利于延长终端的电池寿命。
随着物联网的兴起，在长期演进系统(LTE，Long Term Evolution)系统中支持机器类通信(MTC，Machine Type Communication)越来越受到重视。在3GPP Release 13立项了针对MTC的物理层增强项目。一台MTC设备(MTC终端)可能具有多种M2M(Machine to Machine，机器与机器)通信特性之中的部分特性，如低移动性、传输数据量小、对通信时延不敏感、要求极低功耗等特征。其中，为了降低MTC终端的成本，将新定义一种终端类型，其上行和下行均只支持1.4MHz射频带宽或者更低的系统带宽，例如200KHz。
在D2D的通信过程中，当发送终端不知道接收终端的属性信息时，数据传输可能会超出接收终端的接收限制，例如超出接收带宽，或者最大接收块大小等，导致接收终端不能正确的接收数据。因此，本申请实施例提供了一种D2D通信方法、终端设备和网络设备。
