Description

一种用户设备、网络设备及数据传输方法 技术领域
本申请涉及无线通信领域，尤其涉及一种用户设备、网络设备及数据传输方法。
背景技术
传统的蜂窝无线通信技术中，用户设备通过空口与基站进行通信，通过基站将用户数据转发到网络中的目的节点。
随着移动通信技术的发展，为了更好地满足用户需求，提升用户设备与用户设备之间的信息交互效率，长期演进(Long Term Evolution，简称：LTE)***引入了用户设备之间的直接通信机制，即D2D通信(Device to Device Communication，D2D Communication)，也称为侧行(Sidelink)通信。与传统蜂窝无线通信技术不同的是，用户设备的数据不需要经过基站传输，而是直接通过用户设备和用户设备直接的空口进行传输，从而减少了网络转发的延时。在D2D通信模式中，用户设备之间的直接通信链路可以是在如基站之类的网络设备的控制或辅助下建立起来的。D2D通信典型的应用场景是公共安全场景，如火警组员之间的通信，典型的业务类型是语音业务。
如附图1所示，D2D通信***包括基站101和用户设备(UE)1、UE2，其中基站101和UE1之间可以进行蜂窝无线通信；并且，UE1和UE2之间可以进行D2D通信。
当前D2D通信支持组通信，即一对多通信，D2D用户设备可以发送D2D数据到某个通信组的若干用户设备。如附图2所示，基站201控制或辅助UE1、UE2、UE3和UE4建立了D2D组通信，例如组202是一个公共安全组，UE1可以不经过基站直接向UE2、UE3和UE4传输数据。
当前D2D通信还支持单播通信，即一对一通信，D2D用户设备直接发送D2D数据到某个其它用户设备。
但是，由于传输资源是用户设备竞争获取的，因此目前的D2D通信***可能会存在某些用户设备因竞争不到资源而导致某些数据传输不够及时、不够可靠等问题。

附图说明
为了更清楚地说明本发明实施例的技术方案，下面将对实施例描述所需要使用的附图作简单地介绍，显而易见地，下面描述中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2是本发明现有技术进行一对多D2D传输的示意图；
图3是本发明实施例提供的一种D2D通信资源分配方法的流程示意图；
图4是本发明实施例提供的D2D通信的资源共享模式示意图；

图7是本发明实施例提供的一种网络设备结构示意图。
具体实施方式
虽然在前述背景技术部分以LTE***为例进行了介绍，但本领域技术人员应当知晓，本发明不仅仅适用于LTE***，也可以适用于其他无线通信***，例如GSM，UMTS，CDMA，以及新的网络***等。下面以LTE***为例进行具体实施例的介绍。
D2D通信中，不同用户设备发送的不同的D2D数据的紧急程度可能不同，例如在公共安全场景下，如果当前出现了某个突发状况，可能需要其中一个用户及时用语音的方式将该突发状况通知其他各用户，因此语音数据的优先级可能高于普通文件数据。而且，不同用户设备的重要程度可能不同，比如，一个D2D组中组长使用的用户设备所发送的D2D数据的成功率及及时性应该高于其他用户设备。
现有技术中，D2D通信未对数据的优先级进行划分，不同优先级的D2D数据在相同的逻辑信道中，用户设备无法优先发送高优先级的D2D数据，因此无法保证高优先级数据的服务质量(QoS)。
鉴于上述分析，本发明实施例提供了能够保证高优先级数据优先发送的技术方案。下面对本发明的技术方案进行具体描述。
本发明涉及的网元包括：
用户设备，用于发送上行数据和D2D数据，接收基站发送的下行数据， 接收从其它UE发送的D2D数据。
网络设备：调度用户设备的上行数据传输和D2D传输，接收用户设备发送的上行数据并进行处理，调度并发送用户设备的下行数据。
本领域技术人员应当知晓，本发明所述的用户设备，可以是用户终端、终端设备以及移动台等设备，并且，所述用户设备可以是中继用户设备(relay UE)；本发明所述的网络设备，可以是基站、核心网设备。
实施例1
本实施例的构思是，D2D通信***根据不同类型的D2D数据给用户设备配置相应的资源选择参数，由用户设备根据所述资源选择参数自行选择通信资源进行D2D通信。
下面结合附图3对本发明实施例1的技术方案进行描述。
本实施例的技术方案包括如下步骤：
步骤301，用户设备向网络设备上报其待传输的D2D数据的类型信息；
步骤302，用户设备确定该待传输的D2D数据使用相应的逻辑信道；
步骤303，用户设备确定不同类型的D2D数据的资源选择参数；
步骤304，用户设备根据资源选择参数和自身需要发送的D2D数据，进行通信资源选择，与其它用户设备进行D2D通信。
对于D2D数据的类型信息，包含业务类型和/或优先级类型，等。
对于所述业务类型，在D2D通信***中，通常具有如下几种类型的业务类型：语音业务、数据文件业务、短消息业务，等等。语音业务通常比较紧急，故语音业务的数据优先级别为最高；数据文件业务的紧急情况通常比语音业务要低一些，故数据文件业务的优先级别为中等；短消息业务对实时性要求不高，故短消息业务的数据优先级为优先级别最低。
对于所述优先级类型，***预定义一定数量的D2D数据的不同优先级别。优先级的具体数目可以根据***承载业务的不同、用户设备类别的不同而调整改变，所述优先级信息可以分为：优先级1、优先级2、…、优先 级N，其中所述N为大于1的整数。可以是优先级数值越小，表明所述信息的优先级越高。当然，也可以是优先级数值越大，表明优先级越高。一种具体的优先级数目设置可以为N＝16。本领域技术人员应当知晓也可以根据具体应用场景设置成其它数目，在此不再赘述。
对于D2D数据优先级，可以根据用户设备的不同而不同。一种具体的例子，如果优先级别数为N＝16,优先级数值越小报名信息的优先级越高，重要的用户设备所发送的数据优先级可以为优先级1，普通用户设备所发送的数据优先级可以为优先级4，非重要的用户设备所发送的数据优先级为优先级可以8。
也可以根据用户设备的不同、数据承载的业务类型的不同综合决定数据的优先级，终端的重要性越高、所述终端将要发送的数据所承载的业务类型越紧急，则本次用户设备所发送的数据优先级越高；反之亦然。例如，普通用户设备发送的语音业务的数据优先级为3，重要的用户设备发送的数据文件业务优先级为7；这是由于普通用户设备的语音业务更紧急，故所述数据的优先级反而高于重要用户设备发送不紧急业务的优先级。
上述所有不同类型业务数据的优先级设定、以及所有不用用户设备数据的优先级设定，可以由用户设备和网络设备事先共同约定，并存储在用户设备和网络设备中。。
对于上述所有不同类型的D2D数据进行传输时可以使用的逻辑信道、所述逻辑信道的优先级，可以由用户设备和网络设备事先共同约定，并存储在用户设备和网络设备中。
对于上述步骤301，用户设备向网络设备上报其将要发送的D2D数据的类型信息，用户设备在步骤301中可以仅仅向网络设备上报所述用户设备已经缓存在发送缓冲区中的、将要发送的各个数据业务的类型信息。
另外，步骤301在实际应用中可以省略掉，即用户设备也可以不向网络设备上报其将要发送的D2D数据的类型信息；或者由于传输错误，网络设备 没有收到用户设备上报的类型信息。这种情况下，由于***已经定义了所有的D2D数据类型，网络设备可以知道某个用户设备将要传输的D2D数据的所有可能的类型。这种情况下，网络设备可以为D2D数据的所有类型分配逻辑信道。
另外，步骤301在实际应用中可以在步骤302之前，也可以在步骤303之前执行。以便在用户设备在执行步骤302、303之前获知用户设备待发送的数据类型信息。
对于上述步骤302，用户设备可以只为待发送的D2D数据确定逻辑信道，还可以是确定该用户设备支持的D2D数据的所有类型所对应的逻辑信道。
用户设备可以根据***的资源状况和具体应用环境，将不同类型的D2D数据分配到不同的或者相同的逻辑信道中。
对于所述D2D数据类型为业务类型的情况，例如，可以将语音业务、数据文件业务、短消息业务分别分配到一个逻辑信道中，语音业务D2D数据分配到逻辑信道组1，数据文件业务D2D数据分配到逻辑信道组2，短消息业务D2D数据分配到逻辑信道组3；也可以将语音业务分配到一个逻辑信道中，将数据文件业务和短消息业务分配到一个逻辑信道中。当然，也可以采取其它的逻辑信道分配方式，或者，业务类型逻辑信道的分配方式可以固定分配，在此不再赘述。
对于所述D2D数据类型为优先级类型的情况，例如，优先级数目可以设置为16个，如果所有的用户设备都执行了步骤301，网络设备收到上述多个用户设备的发送数据优先级假如一共只有8种，则可以分配8个逻辑信道，为每一个将要发送的不同优先级别D2D数据分配一个逻辑信道。如果所有的用户设备都未执行步骤301或者部分用户设备未执行步骤301，则网络设备可以判断所有用户设备可能发送的D2D数据优先级别一共是16个，于是网络设备可以配置16个逻辑信道，每一个可能的优先级别D2D数据分配一个逻辑信道。一种具体的逻辑信道和优先级的对应关系可以是：优先级1的D2D数 据使用逻辑信道1，优先级2的D2D数据使用逻辑信道2……优先级N的D2D数据使用逻辑信道N。本领域技术人员应当知晓也可以根据具体应用场景设置其它数目的逻辑信道，以及其它的优先级与逻辑信道对应关系，或者，优先级与逻辑信道的分配方式可以固定分配，在此不再赘述。
所述逻辑信道的分配方式可以包括该待传输的D2D数据的类型与逻辑信道的对应关系，也可以包括D2D数据的所有类型与逻辑信道的对应关系。该分配方式具体可以设置在配置信息中，且用户设备中保存该配置信息。
前面的例子描述了配置信息固化在用户设备的情况，本段的例子描述配置信息由网络设备发送给用户设备。网络设备可以根据***的资源状况和具体应用环境，通过***广播消息和/或专用信令发送配置信息，告知用户设备不同类型的D2D数据使用的逻辑信道。用户设备收到网络设备发送的配置信息后，可以参考该配置信息，结合用户设备自身的状况，确定不同类型D2D数据使用的逻辑信道。另外，在用户设备执行了步骤301的情况下，网络设备可以获知所有执行了步骤301的用户设备的D2D数据业务类型，这样网络设备根据用户设备上报的D2D数据类型种类情况，向用户设备发送配置信息，为用户设备上报的所述类型的D2D数据分配逻辑信道，此时配置信息可以包含所述分配的逻辑信道的标识，比如逻辑信道号。配置信息由网络设备发送给用户设备的情况下，网络设备还可以根据用户设备的类型确定配置信息。例如，可以将用户设备分为高级用户，普通用户和低级用户等，为不同类型的用户设备分配不同的逻辑信道。另外，网络设备还可以结合用户类型与D2D数据的类型来分配逻辑信道。
对于上述步骤303，用户设备可以只为待发送的D2D数据确定资源选择参数，还可以是确定该用户设备支持的D2D数据的所有类型所对应的资源选择参数。
所述资源选择参数规定了不同类型D2D数据可以使用或者不能使用D2D通信资源的条件，用户设备根据所述资源选择参数并结合其将要发送数据 的类型信息，即可自行判断所述用户设备是否能够占用D2D通信资源进行当前数据的发送操作。
如前所述，所述的不同类型D2D数据包括不同的业务类型和/或优先级类型，在步骤302中，用户设备已经将要传输数据的业务类型和/或优先级与逻辑信道建立了对应关系，因此在步骤303中用户设备确定不同类型D2D数据的资源选择参数，等同于确定不同逻辑信道的资源选择参数。
对于所述资源选择参数，一种具体的形式为资源退避参数，所述资源退避参数包括占用资源概率和/或退避占用资源时间。
对于所述占用资源概率，其规定了各个不同类型D2D数据要发送时能够占用***的D2D通信资源中某个资源块的概率，所述占用资源概率值越大，代表该类型D2D数据发送时占用D2D通信资源的概率越大，即该优先级的D2D数据被发送的概率越大。下面以不同类型D2D数据是优先级类型为例进行描述，例如，对于优先级为1的D2D数据，其被配置使用逻辑信道1，其占用资源概率A被设置为最高，例如A可以为1；对于优先级为8的D2D数据，其被配置使用逻辑信道8，其占用资源概率B被设置为中等，例如B可以为0.5；对于优先级为16的D2D数据，其被配置使用逻辑信道16，其占用资源概率为C被设置为最低，例如C可以为0.1；其中A、B、C为大于0且小于等于1的实数，且A大于B，B大于C。对于不同类型D2D数据是业务类型的情况，与前述例子类似，每个不同业务类型的D2D数据配置的占用资源概率各不相同，在此不再赘述。
对于所述退避占用资源时间，其规定了各个不同类型的D2D数据要发送时，属于一个类型的D2D数据两次使用D2D通信资源进行传输的最小间隔时间，所述退避占用资源时间值越大，代表该类型D2D数据发送时等待占用D2D通信资源的时间越长，即该类型的D2D数据需要等候发送的时间越长。下面以不同类型D2D数据是优先级类型为例进行描述，例如，对于优先级为1的D2D数据，其被配置使用逻辑信道1，其退避占用资源时间D被设置为最短， 例如D可以为0；对于优先级为8的D2D数据，其被配置使用逻辑信道8，其退避占用资源时间E被设置为中等，例如E可以为15毫秒；对于优先级为16的D2D数据，其被配置使用逻辑信道16，其退避占用资源时间F被设置为最长，例如F可以为50毫秒。其中D、E、F为大于或等于0的整数，且D小于E，E小于F。对于不同类型D2D数据是业务类型的情况，与前述例子类似，每个不同业务类型的D2D数据配置的占用资源时间各不相同，在此不再赘述。
在步骤303中，资源选择参数中还可以包括如果可以使用D2D通信资源时，不同类型D2D数据要发送时可以占用D2D通信资源中资源量大小。下面以不同类型D2D数据是优先级类型为例进行描述，网络设备可以配置优先级越高的D2D数据，其每次可以占用的资源量越大，优先级越低的D2D数据，其每次可以占用的资源量越小。例如用户设备发送高优先级的数据时，每次选择资源时最多可以选择10个物理层资源块(Physical Resource Block,PRB)，用户设备在发送低优先级数据时，每次选择资源时最多只能选择2个物理层资源块。对于不同类型D2D数据是业务类型的情况，与前述例子类似，每个不同业务类型的D2D数据配置的占用资源量大小各不相同，在此不再赘述。
对于所述资源选择参数，可以***预先配置，并存储或固化在用户设备中，则用户设备确定D2D数据使用的逻辑信道后即可自行确定该类型D2D数据的资源选择参数；资源选择参数也可以由网络设备生成，并发送给用户设备，网络设备可以根据***的资源状况和具体应用环境，生成资源选择参数并通过通过***广播消息和/或专用信令发送给用户设备。网络设备可以生成至少一个资源选择参数，所述至少一个资源选择参数中包括为所述D2D***中每个类型的D2D数据配置的资源选择参数；所述网络设备根据所述待传输D2D数据的类型从所述至少一个资源选择参数中，选择所述所述D2D数据对应的资源选择参数；或者，所述网络设备可以为所述D2D***中所有类型的D2D数据生成一个资源选择参数，所述资源选择参数规定了每种 D2D数据能够使用或者不能使用D2D通信资源的条件。
用户设备收到网络设备发送的资源选择参数后，可以参考该资源选择参数，结合用户设备自身的状况，确定不同类型D2D数据的最终资源选择参数。另外，在用户设备执行了步骤301的情况下，网络设备可以获知所有执行了步骤301的用户设备的D2D数据业务类型或者优先级类型，这样网络设备根据用户设备上报的业务类型种类情况或者优先级类型种类情况，为用户设备上报的所述业务类型或者优先级类型的D2D数据分配资源选择参数。网络设备可以通过***广播消息和/或专用信令发送消息，告知用户设备不同业务类型或优先级类型的D2D数据使用的资源选择参数。资源选择参数由网络设备发送给用户设备的情况下，网络设备还可以根据用户设备的类型确定配置信息。例如，可以将用户设备分为高级用户，普通用户和低级用户等，为不同类型的用户设备分配不同的资源选择参数。
对于上述步骤304，在此实施例中，用户设备根据在步骤303确定的资源选择参数，并考虑所述用户设备将要发送的D2D数据的类型，自行判断所述用户设备能否使用D2D通信资源或者何时能够使用D2D通信资源，在可以使用D2D通信资源的情况下，选择并使用D2D通信资源，通过步骤302确定的逻辑信道，与其它用户设备进行D2D通信。
具体而言，针对上述步骤303，对于所述资源选择参数包含占用资源概率的情形，用户设备在自行选择D2D通信资源前，对于每个D2D资源的资源块，产生一个随机数R，其为取值大于0且小于1的实数。如果所述用户设备将要发送优先级为优先级1或者逻辑信道为1的D2D数据，则用户设备判断随机数R与数据对应的退避占用资源概率值A的大小，如果A大于R，则所述用户设备可以自行选择该资源块中的D2D通信资源进行D2D通信，否则等待下一D2D资源块重新产生随机数R’再次进行选择。如果所述用户设备将要发送优先级为其它级别的D2D数据，判断步骤类似，分别判断R与占用资源概率值B、C的大小，在此不再赘述。
对于所述资源选择参数包含退避占用资源时间的情形，用户设备在自行选择D2D通信资源前，直接根据所述用户设备将要发送的D2D数据的类型，等待所述类型D2D数据对应的退避占用资源时间，然后再占用D2D通信资源进行D2D通信。如果所述用户设备将要发送优先级为1的D2D数据，则所述用户设备等待D毫秒，中级、低级D2D数据的等待步骤类似，在此不再赘述。
在步骤304之前，网络设备可以通过***消息和/或专用信令来配置用户设备用于D2D通信的资源配置信息。
所述资源配置信息有两种配置方式：共享模式和专用模式。
对于所述共享模式，如附图4所述，D2D通信使用的资源位于原本***划分给用于蜂窝上行传输的资源范围，如LTE***的上行载波或上行子帧中，用于D2D通信的资源与用于蜂窝上行传输的资源在时间上分开或者在频率上分开。对于共享模式，所述资源配置信息包括蜂窝上行资源中用于D2D通信的频率资源信息和时间资源信息，其中所述频率资源信息包括蜂窝上行资源中可以用于D2D通信的频率和带宽，所述时间资源信息为可以用于D2D通信的时间段。
对于所述专用模式，如附图5所述，D2D通信使用的资源位于原本***划分给用于蜂窝上行传输的资源(如LTE***的上行载波或上行子帧)范围之外，即***专为D2D通信划分资源。对于专用模式，所述资源配置信息包括蜂窝上行资源外用于D2D通信的载波信息和/或时间信息，其中所述载波信息包括蜂窝上行资源外可以用于D2D通信的频率和带宽，对于时分的***，所述时间信息可以为***的载波可以用于D2D通信的时间段。由于专用模式下D2D通信资源与蜂窝上行资源没有重叠，故D2D通信与蜂窝上行传输不会产生相互干扰。
对于所述网络设备配置用户设备用于D2D通信的资源配置信息的步骤，网络设备向用户设备发送D2D通信资源配置信息可以在用户设备开机附着时进行，也可以在用户设备变更服务区时进行，网络设备还可以定时 发送资源配置信息或者网络设备根据网络占用情况在需要发送时发送资源配置信息。本领域技术人员可以根据具体应用场景进行选择，在此不再赘述。
对于在步骤304前具有所述网络设备配置用户设备用于D2D通信的资源配置信息步骤的情形，在步骤304中，每个用户选择的D2D资源都位于网络设备配置的D2D通信资源内。
通过本实施例上述方式的设置，用户设备可以根据网络设备发送的资源选择参数自行判断能否占用D2D通信资源，给某些类型的D2D数据分配传输资源，大大提高D2D数据传输的效率。

在实际应用中，用户设备601也可以不向网络设备701上报其待发送的D2D数据的类型信息；或者由于传输错误，网络设备701没有收到用户设备601上报的类型信息。这种情况下，由于***已经定义了所有的D2D数据的类型，网络设备可以知道某个用户设备将要传输的D2D数据的所有可能的类型信息。

用户设备601的处理单元602根据所述配置信息和用户设备待发送D2D的类型，确定其待发送D2D数据的逻辑信道。
在用户设备601将待发送D2D数据类型信息传送给网络设备701的情况 下，网络设备701可以获知所有上传待发送D2D数据类型信息的用户设备的D2D数据类型，这样网络设备701的处理单元702可以根据用户设备上报的数据类型种类情况生成一个配置信息，通过发送单元703经由***广播消息和/或专用信令发送向用户设备发送所述的配置信息，为用户设备上报的所述类型的D2D数据分配逻辑信道组，此时配置信息包含所述配置的逻辑信道号。用户设备的接收单元604接收上述配置信息后传送给处理单元602。配置信息由网络设备发送给用户设备的情况下，网络设备还可以参考用户设备的类型。例如，可以将用户设备分为高级用户，普通用户和低级用户，为不同类型的用户设备分配不同的逻辑信道。
对于资源选择参数，用户设备601的处理单元602可以只为待发送的D2D数据确定资源选择参数，还可以是确定该用户设备支持的D2D数据的所有类型所对应的资源选择参数。资源选择参数的作用和具体产生方式与实施例1中步骤303完全相同，例如具体的形式为资源退避参数，所述资源退避参数包括占用资源概率和/或退避占用资源时间，还可以包括如果可以使用D2D通信资源时每次可以占用D2D通信资源中资源量大小，在此不再赘述。
对于所述资源选择参数，可以***预先配置，并存储或固化在用户设备中，例如存储在用户设备601的存储单元605中，则用户设备601的处理单元602确定D2D数据使用的逻辑信道后即可自行确定该类型D2D数据的资源选择参数；资源选择参数也可以由网络设备701的处理单元702生成，并通过发送单元703发送给用户设备，处理单元702可以根据***的资源状况和具体应用环境，生成资源选择参数并通过通过***广播消息和/或专用信令发送给用户设备。用户设备601的接收单元604收到网络设备发送的资源选择参数后发送给处理单元602，处理单元602可以参考该资源选择参数，结合用户设备601自身的状况，确定不同类型D2D数据的最终资源选择参数。所述处理单元601可以生成至少一个资源选择参数，所述至少一个资源选择 参数中包括为所述D2D***中每个类型的D2D数据配置的资源选择参数；所述处理单元601根据所述待传输D2D数据的类型从所述至少一个资源选择参数中，选择所述所述D2D数据对应的资源选择参数；或者，所述处理单元601可以为所述D2D***中所有类型的D2D数据生成一个资源选择参数，所述资源选择参数规定了每种D2D数据能够使用或者不能使用D2D通信资源的条件。
另外，在用户设备601执行了步骤301的情况下，网络设备701可以获知所有执行了步骤301的用户设备的D2D数据业务类型或者优先级类型，这样网络设备701的处理单元702根据用户设备上报的业务类型种类情况或者优先级类型种类情况，为用户设备上报的所述业务类型或者优先级类型的D2D数据分配资源选择参数。网络设备701的发送单元703可以通过***广播消息和/或专用信令发送消息，告知用户设备不同业务类型或优先级类型的D2D数据使用的资源选择参数。资源选择参数由网络设备701发送给用户设备601的情况下，网络设备701的处理单元702还可以根据用户设备的类型确定配置信息。例如，可以将用户设备分为高级用户，普通用户和低级用户等，为不同类型的用户设备分配不同的资源选择参数。
用户设备601的处理单元602根据确定的资源选择参数，并考虑所述用户设备将要发送的D2D数据的类型，自行判断所述用户设备能否使用D2D通信资源或者何时能够使用D2D通信资源，在可以使用D2D通信资源的情况下，处理单元602选择并使用D2D通信资源，通过处理单元602确定的逻辑信道，与其它用户设备进行D2D通信。
具体而言，以实施例1中记载的所述资源选择参数包含占用资源概率的情形，处理单元602在自行选择D2D通信资源前，对于每个D2D资源的资源块，产生一个随机数R，其为取值大于0且小于1的实数。如果所述用户设备将要发送优先级为优先级1或者逻辑信道为1的D2D数据，则处理单元602判断随机数R与数据对应的退避占用资源概率值A的大小，如果A大于R，则所 述处理单元602可以自行选择该资源块中的D2D通信资源进行D2D通信,发送单元603可以使用选中的D2D通信资源将待发送的优先级1或者逻辑信道为1的数据发送给其它用户设备，否则等待下一D2D资源块重新产生随机数R’再次进行选择。如果所述用户设备将要发送优先级为其它级别的D2D数据，判断步骤类似，分别判断R与占用资源概率值B、C的大小，在此不再赘述。
对于实施例1中记载的所述资源选择参数包含退避占用资源时间的情形，处理单元602在自行选择D2D通信资源前，直接根据所述用户设备将要发送的D2D数据的类型，控制用户设备601的发送单元602等待所述类型D2D数据对应的退避占用资源时间，然后发送单元603再占用D2D通信资源进行D2D通信。如果所述用户设备将要发送优先级为1的D2D数据，则所述用户设备的发送单元603等待D毫秒，中级、低级D2D数据的等待步骤类似，在此不再赘述。
网络设备701的发送单元703可以通过***消息和/或专用信令来配置用户设备用于D2D通信的资源配置信息。用户设备601的接收单元接收上述资源配置信息并发送给处理单元602。所述资源配置信息有两种配置方式：共享模式和专用模式，具体的介绍与实施例1完全相同，不再赘述。
对于具有所述网络设备701配置用户设备601用于D2D通信的资源配置信息步骤的情形，用户设备601的处理单元接收到该资源配置信息后，控制每个用户选择的D2D资源都位于网络设备701配置的D2D通信资源内。
在本发明各个实施例中的各功能单元可以集成在一个处理单元中，也可以是各个单元单独物理存在，也可以是两个或两个以上单元集成在一个单元中。上述集成的单元既可以采用硬件的形式实现，也可以采用软件功能单元的形式实现。
所述集成的单元如果以软件功能单元的形式实现并作为独立的产品销售或使用时，可以存储在一个计算机可读取存储介质中。基于这样的理解， 本发明的技术方案本质上或者说对现有技术做出贡献的部分，或者该技术方案的全部或部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质中，包括若干指令用以使得一台计算机设备(可以是个人计算机，服务器，或者网络设备等)执行本发明各个实施例所述方法的全部或部分步骤。而前述的存储介质包括：U盘、移动硬盘、只读存储器(ROM，Read-Only Memory)、随机存取存储器(RAM，Random Access Memory)、磁碟或者光盘等各种可以存储程序代码的介质。
在本申请所提供的几个实施例中，应该理解到，所揭露的***、装置和方法，可以通过其它的方式实现。例如，以上所描述的装置实施例仅仅是示意性的，例如，所述单元的划分，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式，例如多个单元或组件可以结合或者可以集成到另一个***，或一些特征可以忽略，或不执行。另外，所显示或讨论的相互之间的耦合或直接耦合或通信连接可以是通过一些接口、装置或单元的间接耦合或通信连接，也可以是电的，机械的或其它的形式连接。
