Description

信息处理方法、用户设备和计算机存储介质 技术领域
本发明涉及通信领域的资源竞争和使用技术，尤其涉及一种信息处理方法、用户设备和计算机存储介质。
背景技术
随着移动通信业务和应用场景的多样化，例如，公共安全、车联网、现场指挥、社交网络、电子支付等应用在无线通信系统中的普及，使得近距离用户之间的业务传输需求日益增长。如近距离用户之间的设备到设备(Device-to-Device，简称为D2D)的通信模式、车到车(Vehicle to vehicle，简称V2V)以及其他类似的用户设备到用户设备的通信模式等，由于可以应用于灾难救援等公共安全场景，也可以应用于商业场景下节省用户设备功耗并且提高频谱利用率，因此日益受到广泛关注。
在蜂窝通信中，当两个用户设备(User Equipment，UE)进行通信时，一般情况下UE所使用的资源由网络侧设备(如基站或者接入节点)来统一分配，该网络侧设备这里称之为中心节点。而对于无中心节点的无线通信场景，或有中心节点但资源分配方式为用户设备竞争的场景，UE只能依靠自身获得的信息来选择使用资源，通常使用自主随机选择资源方式。该方式会导致较高的资源冲突问题(两个或两个以上用户设备选择相同的资源)，并且不能满足有些紧急业务或高等级的设备的通信要求。

以下结合说明书附图及具体实施例对本发明的技术方案做进一步的详细阐述，应当理解，以下所说明的优选实施例仅用于说明和解释本发明，并不用于限定本发明。
方法实施例一：
如图1所示，本实施例提供一种信息处理方法，所述方法包括：
步骤S110：确定用户设备的优先级；
步骤S120：若所述用户设备的优先级为第一优先级且预定在第n通信 周期有待发数据，在第n-m通信周期发送通告信号；
其中，所述n为不小于m的整数；m为大于或等于零的整数。所述通告信号用于告知其他用户设备所述第一优先级的用户设备将参与第n通信周期的资源竞争或使用。
在本实施例中用户设备的优先级分为第一优先级和第二优先级。所述第一优先级和第二优先级的划分可以根据用户设备的用户设备属性或用户设备第n通信周期需要发送的数据的业务类型来确定的。所述用户设备属性包括用户设备的设备类型、所述用户设备归属的群组的组属性和支持的通信制式的类型等类型参数其中一个或多个。
所述业务类型不同包括：业务的通信要求不同，具体如对通信可允许的时延性不同或通信质量要求不同或业务的重要性不同等。通常所述可允许的时延性越大，则可能对应的优先级为第二优先级的概率更高，在具体实现时，可直接根据业务类型来确定。
所述优先级可以为预先设置在用户设备中，或由用户设备的协议层确定，也可以从所述用户设备的接入节点中获取的。所述接入节点可为基站或其他中心节点等通信节点，可用于所述用户设备接入到移动网络。所述接入节点可通过配置信息的发送来告知用户设备的优先级。
用户设备的优先级确定了之后，如第一优先级的用户设备确定预定在第n通信周期进行数据传输，则在第n-m周期发送通告信号。所述通告信号以广播的形式发送，这样位于其附近的参与同一资源竞争的其他用户设备都能接收到，方便第二优先级的用户设备确定第n通信周期的资源竞争和使用；具体如选择退避机制确定不参与第n通信周期的资源竞争或使用。这样能够降低第n通信周期的资源竞争冲突的激烈程度，保证高优先级的用户设备有更高的几率竞争到通信资源。
在本实施例中所述用户设备通常可为D2D用户设备或V2V用户设备等 应用在无中心节点或中心节点不参与资源分配的通信系统中。所竞争的资源可为授权频谱或非授权频谱的通信资源。
若所述第n-m通信周期为当前通信周期，则第n通信周期为当前通信周期之后的第m通信周期。所述通告信号可用于第二优先级的用户设备来确定其是否参与第n通信周期的资源竞争或资源竞争参数等相关信息。
假定正在执行本实施例所述方法的用户设备为第一用户设备，则在步骤S110中若所述第一用户设备内预置有执行本实施例所述信息处理方法第一用户设备的优先级，所述步骤S110可包括从预置有所述优先级的存储位置，读取所述第一用户设备的优先级，也可以从用户设备的协议高层配置所述优先级。或者所述第一用户设备从接入节点或中心节点等网络侧设备获取所述优先级，可包括从网络侧设备接收配置信息，解析配置信息获取所述第一用户设备的优先级。在具体实现时，所述步骤S110的执行时机可为所述第一用户设备确定在第n通信周期有数据要发送时，采取确定所述第一用户设备的优先级。所述网络侧设备还可以为演进型基站eNB、小小区基站或更为上层的网络节点，如网关，或移动性管理实体MME等网络设备。值得注意的是：这里的第一用户设备可以泛指任意一个用户设备。
在步骤S120中，当确定出所述第一用户设备的优先级为第一优先级且确定在第n通信周期有待发送数据，则在第n-m通信周期发送所述通告信号。
所述通告信号优选为能量信号，当所述通告信号为能量信号时，第二优先级的UE检测到所述通告信号的能量，在不解析所述通告信号的具体信息内容的前提下，就能确定所述第一优先级的UE有发送了通告信号，将参与第n通信周期的资源竞争和使用。所述通告信号也可以为近距离通信的控制信息内容的一部分。这里的近距离通信可包括D2D通信，或V2X通信或其他设备与设备的直接通信。所述V2X为vehicle to Everything的缩写， 对应的中文可为车载设备与其他设备的通信。
在步骤S120中所述第一优先级的UE可以在第n-m通信周期的任意一种数据帧、子帧或传输符号上来发送所述通告信号。第一优先级的UE可以通过是否在指定的时频资源上来发送信息来表示其是否有通告信号的发送，也可以在任意第n-m通信周期的任意时频资源发送所述通告信号，是否是通告信号可以由所述信息内容表示。
在步骤S120中发送通告信号的方式有多种，以下介绍几种实现简便的方式。
方式一：
所述步骤S120包括：
利用所述第n-m通信周期的同步子帧发送所述通告信号。
一个时长为1ms的同步子帧通常包括2个时长为0.5ms的时隙；而每一个时隙包括6个或7个传输符号，所述传输符号可OFDM符号或SC-FDMA符号。所述OFDMA为Orthogonal-Frequency Division Multiplexing的缩写，对应的中文为正交频分多址。所述SC-FDMA为Single Carrier Frequency Division Multiplexing的缩写，对应的中文为单载波频分多址。
图2所示的为同步子帧的子帧格式的一种；在图2中第1个时隙的第1个和第2个传输符号中传输的为D2D通信的主同步信号PD2DSS；第2个时隙的第4个和第5个传输符号中传输的为D2D通信的辅助同步信号SD2DSS。在图2中在同步子帧的第1个时隙的第0个传输符号来传输所述通告信号(Announce Signal，AS)。
值得注意的是：AS的时域位置不限定于同步子帧的第一个符号位置，也不限定仅占用一个符号。AS信号的频域带宽可以为与同步信号相同的6个资源块RB，也可以为其他全部或部分可用带宽。AS的资源位置可以由网络侧设备配置或预配置的方法确定。此处的网络侧设备可以为接入节点， 如用户设备，等设备。
在这个实施例中，所述的资源抢占方式至少包括第一优先级用户设备UE在同步子帧的AS资源发送通告信号，需要检测AS的UE监听并检测AS信道。这里需要检测所述AS的UE可包括任意一个没有发送所述AS的UE，但至少包括第二优先级的UE。
利用同步子帧来发送通告信号，所述同步子帧为发送同步信号的子帧，或配置了同步子帧资源的子帧。利用同步子帧来发送通告信号，又至少可分为两种模式：
模式一：
所述利用所述第n-m通信周期的同步子帧发送所述通告信号，包括：
形成通告信号；
利用所述同步子帧的时频资源发送所述通告信号。
在图2中即为通告信号单独占用了所述同步子帧的时频资源，即不与其他同步序列等信息进行时频资源的复用。
模式二：
所述同步子帧为用于发送同步序列的子帧；
所述同步序列包括第一类同步序列和第二类同步序列；所述第一类同步序列不同于第二类同步序列；
所述利用所述同步子帧的时频资源发送所述通告信号，包括：
利用同步子帧发送第一类同步序列；
其中，所述第一类同步序列用于同步，同时还用于告知其他用户设备所述第一优先级的用户设备将参与第n通信周期的资源竞争。
所述第一类同步序列不仅用于进行用户设备之间的同步，还用于第一优先级的用户设备告知其他用户设备如第二优先级的用户设备，发送通告信号的第一优先级的用户设备将参与第n通信周期的资源竞争，让第二优 先级的用户设备选择避让资源竞争或调整参与竞争的概率等。
在具体实现时，所述利用子帧发送第一类同步序列包括：生成第一类同步序列的步骤。用户设备生成同步序列的方式至少包括两种，当用户设备为第一优先级的用户设备且需要发送通告信号时，选择第二种生成同步序列的方式，否则选择第一种生成同步序列的方式；第二种生成同步序列的方式和第一种生成同步的方式生成的同步序列不同。
同步序列分为主同步序列和辅同步序列，在本申请中所述第一类同步序列和第二类同步序列优选为对所述辅同步序列的子分类。

Figure PCTCN2016079001-appb-000002
通常同步序列可以由多位组成，其中，d(2n)表示的为偶数位的值；d(2n+1)表示的奇数位的值；所述n的取值为从0开始的整数。所述
Figure PCTCN2016079001-appb-000003
和
Figure PCTCN2016079001-appb-000004
为两个不同的循环位移M序列；所述c0(n)和c0(n)为两个不同的加扰序列；
Figure PCTCN2016079001-appb-000005
和
Figure PCTCN2016079001-appb-000006
为两个不同的加扰序列。M序列和加扰序列的具体构成可以参见长期演进LTE系统中辅同步序列中的定义，在此就不一一详细叙述了。
所述公式中第一种表示的上述第一种生成同步序列的方式；第二种表示的为第二种生成同步序列的方式。
在具体的实现过程中，还可以预先为预先生成了所述同步序列，在进行同步序列发送时，依据所述用户设备的优先级及是否需要在第n通信周期进行数据从第一类同步序列或第二类同步序列中选择一个序列的方式也可。如若所述用户设备的优先级为第一优先级且在第n通信周期需要发送数据，则选择第一类同步序列，否则选择第二类同步序列。
方式二：
所述步骤S120可包括：
将所述通告信号承载在第n-m通信周期的数据子帧的指定传输符号上发送所述通告信号。
所述数据子帧为传输业务数据的子帧。所述指定传输符号可选最后一个传输符号。在图3所示的数据子帧为在数据子帧的最后一个传输符号上发送所述通告信号。所述指定传输符号还可以是其他传输符号，如第一个传输符号等。
图3所示的仅为AS在数据子帧中的位置一个示例，AS位于数据子帧的最后一个符号位置，也可以重定义其他符号用于AS信号发送。AS信号的时域持续时长为t(t小于或等于一个传输符号时长)。频域带宽不作限制，在可用带宽范围内即可。图3中虚线框表示的AS占用的时间长度t，显然小于一个传输符号的时间长度。
方式三：
所述通告信号包括至少一个通告标识位；
所述在第n-m通信周期发送通告信号，包括：
利用第n-m通信周期的SA子帧发送通告标识位。
所述SA为Schedule Assignment的缩写，对应的中文为调度分配；所述SA子帧是利用控制信道发送的子帧，是承载有调度分配SA信息的子帧，具体如在D2D通信中，所述控制信道为PSCCH信道；所述PSCCH为Physical Sidelink Control Channel的缩写，对应的中文为D2D通信物理控制信道。
所述通告标识位可为占用一个比特或多个比特或隐含指示，当所述通告标识位仅为一个比特时，该比特的取值为0或1对应的第一优先级的第一用户设备在第n通信周期是否有数据待发送的两种不同状态。
具体如，通告信号(AS)定义在当前周期以后的第m个通信周期有业 务需求的第一优先级UE在当前通信周期内SA内容中(PSCCH信道)发送AS。其中，AS包含1bit，1表示抢占当前周期以后的第m个通信周期的资源，0表示不抢占当前周期以后的第m个通信周期的资源。SA定义新的格式，增加AS标识域(ASFlag，1bit)，用来发送AS。
通信的资源分配具有周期性，每个通信周期，通信UE首先在SA资源池上发送SA调度信息。该实施例中，第一优先级UE在第n通信周期有业务发送需求，则可选择新定义的SA格式，在当前周期内的SA内容的ASFlag域发送AS。携带AS的SA，可以为第n-m通信周期的数据的调度SA，也可以单独发送一个SA，但其并不用于指示第n-m通信周期的数据传输，进一步地，可以为此类专门用来发送AS信息的SA在SA子帧中定义专用的时频资源。
上述定义的需要检测AS的UE，如果发现接收到的SA内容中，ASFlag域为1，则表示有第一优先级UE参与第n通信周期的资源竞争，则低优先级UE可放弃第n周期的资源竞争或使用，或以较低的概率p选择参与资源竞争，p小于等于1。
此外，新的SA格式中，可以定义表示业务优先级的域(Priority Area，PA)，上述定义的需要检测AS的UE，可以依据该PA信息，判断自己是否参与第n周期的资源选择。
在这个实施例中，所述的资源竞争方式至少包括第一优先级UE发送携带AS信息(ASFlag)的SA格式，需要检测AS的UE接收SA，发现ASFlag域为1，则放弃第n周期的资源占用或以较低的概率选择占用资，即空出更多的资源由第一优先级UE使用。
所述步骤S120可包括：利用确定的时频资源发送所述SA信息；其中，所述通告信号的信息内容与发送SA信息的时频资源具有映射关系。
例如，当所述通告信号对应的通告标识为1时，则SA子帧在第一时频 资源发送SA信息，若所述通告标识位为0时，则在第二时频资源发送SA信息，或者若在第一时频资源上没有收到SA，则认为通告标识为0。所述第一时频资源和第二时频资源为SA资源池中的特定位置的资源块，这样UE可根据发送SA的时频资源位置确定出所述通告标识，即确定出所述通告信号的信息内容。
方法实施例二：
如图3所示，本实施例提供一种信息处理方法所述方法包括：
步骤S210：确定用户设备的优先级；
步骤S220：若所述用户设备的优先级为第二优先级，在第n-m通信周期检测第一优先级的用户设备发送的通告信号；
步骤S230：依据所述通告信号，确定所述第n通信周期的资源竞争或使用的相关信息。所述n为不小于m的正整数；所述m为大于或等于零的整数。
本实施例所述的方法为应用在第二优先级的用户设备中。
此处的n与方法实施例中一样，选取可为不小于2的整数，所述通信周期的计数可从1开始。在步骤S220中优选为所述第二优先级的UE在第n通信周期有待发送数据时，则在第n-m周期检测所述通告信号，以减少UE的检测次数，节省UE的功耗。
在步骤S230中所述相关信息，可以包括重新确定的资源竞争的起始时间，具体如修改原本预定的在第n通信周期进行资源竞争的起始时间，修改到第n+i个通信周期进行资源竞争。所述i为不小于1的整数，此时，显然第二优先级的用户设备在第n通信周期将会避让所述第一优先级的用户设备。此外，第二优先级的用户设备还可以直接进行避让退出资源竞争时间的确定，确定是否采用其他通信方式来进行通信，如转而通过基站等方式向目标UE发送数据等。此外，所述步骤S230还可包括：当所述通告信 号表明所述第一优先级的用户设备将参与所述第n通信周期资源竞争或使用时，以第一概率参与所述第n通信周期资源的竞争或使用；其中，当未接收到所述通告信号或所述通告信号表明所述第一优先级的用户设备将不参与所述第n通信周期资源竞争或使用时，所述第二优先级的用户设备将以第二概率参与所述第n通信周期资源的竞争或使用；所述第一概率小于所述第二概率。所述第二概率的最大取值可为1。所述第一概率和第二概率可以由基站等中心节点或网络侧设备来配置，也可以采用用户设备预配置的方式来配置。例如，所述通告信号包括通告标识位，若所述通告标识位为1表示第一优先级的UE参与第n通信周期资源的竞争或使用，则第二优先级的UE在接收到所述通告信号之后，以第一概率参与第n通信周期资源的竞争或使用，否则将以高于第一概率的第二概率参与第n通信周期资源的竞争或使用。
所述步骤S220可包括：检测所述第n-m通信周期的同步子帧；及从所述同步子帧上获取所述通告信号。
此处，对所述通告信号的检测可以对应前述的方式一；而从同步子帧上接收信号又至少分为以下两个方式。
第一种方式：
所述从所述同步子帧上获取所述通告信号，包括：
从所述同步子帧的指定时频资源上提取所述通告信号。具体如在所述同步子帧的指定时频资源上解码所述通告信号。通常此时所述通告信号单独占用了所述同步子帧对应的时频资源。
第二种方式：
所述从所述同步子帧上获取所述通告信号，包括：
提取所述同步子帧上的同步序列；
判断所述同步序列是第一类同步序列还是第二类同步序列；
若所述同步序列为第一类同步序列则确定有接收到所述通告信号。
对应于前述作为第一优先级的用户设备发送的通告信号的方式二，作为第二优先级的用户设备还可以从数据子帧上获取所述通告信号。具体如，从所述第n-m通信周期的数据子帧的指定传输符号上获取所述通告信号。此处的指定传输符号可为最后一个传输符号，也可以为第一个传输符号等。
此外，对应于前述传输通告信号的方式三，以下介绍一下作为第二优先级的用户设备的用户设备是如何从控制信道上接收所述通告标识位的。
所述通告信号包括至少一个通告标识位；
所述在第n-m通信周期检测第一优先级的用户设备发送的通告信号，包括：
从所述第n-m通信周期的SA子帧上获取所述通告标识位。
图5是本发明实施例资源竞争的另一个示例。
将用户设备UE分类；分为第一优先级和第二优先级的用户设备。
在第n通信周期有数据发送时，第一优先级的用户设备发送ASFlag；第二优先级的用户设备接收并判断ASFlag的值，当ASFlag＝0时，参与资源竞争或使用；当ASFlag＝1时，放弃本次资源竞争或使用，或选择以第一概率参与资源竞争。所述ASFlag即为上述通告标识位。
在具体的实现过程中，当所述第一用户设备的优先级为第二优先级时，所述用户设备还可在接收到第一优先级的用户设备的通告信号之后，为了保证更多的第二优先级设备能够接收到该通告信号，减少在第n通信周期参与竞争的用户设备的个数，第二优先级的用户设备，还可以选择转发所述第一优先级用户设备发送的所述通告信号。
值得注意的是本实施例提供了一种信息处理方法，主要用于优先级为第二优先级的UE中，用户设备UE的优先级的划分可以参见方法实施例一中对应的部分，总之所述优先级的划分可以是动态的也可以是静态的；能 够与应用于第一优先级的UE中如实施例中所述方法共同实现降低资源竞争的激烈程度，提高第一优先级的UE竞争到资源的概率。
以下结合具体实施例提供几个示例：
示例一：
在无基站等中心节点或中心节点不参与资源分配的通信场景下，第一优先级的UE在需要占用资源进行数据发送时，在当前通信周期的同步子帧新增的信道中发送通告信号。第二优先级的UE在接收到所述通告信号后，确定在当前通信周期以后的第m个通信周期不参与资源竞争或以第一概率参与资源竞争或使用，使第一优先级的UE有更大的几率竞争到资源，缓解竞争冲突的激烈程度。此处，所述新增的信道即为同步子帧中专门设置用于发送所述通告信号的时频资源。
示例二：
在无基站等中心节点或中心节点不参与资源分配的通信场景下，第一优先级的UE在需要占用资源进行数据发送时，采用第一种生成同步序列的方式生成第一类同步序列，在当前通信周期的同步子帧发送所述第一类同步序列。此时，所述第一类同步序列既作为同步序列用于同步，同时还复用为前述的通告信号AS。第二优先级的UE在接收到所述第一类同步序列后，将认为是接收到了第一优先级的UE发送的通告信号，认为第一优先级的UE将参与当前通信周期以后的m个通信周期的资源竞争，于是确定在后m个通信周期不参与资源竞争或以第一概率参与资源竞争，使第一优先级的UE有更大的几率竞争到资源，缓解竞争冲突的激烈程度。此处，所述新增的信道即为同步子帧中专门设置用于发送所述通告信号的时频资源。
示例三：
在无基站等中心节点或中心节点不参与资源分配的通信场景下，第一优先级的UE在需要占用第n周期的资源进行数据发送时，在第n-m通信 周期的数据子帧的指定传输符号，如最后一个传输符号，发送通告信号。第二优先级的UE从所述数据子帧上接收通告信号，且在接收到所述通告信号后，确定在第n通信周期不参与资源竞争或以第一概率参与资源竞争，使第一优先级的UE有更大的几率竞争到资源，缓解竞争冲突的激烈程度。
示例四：
在无基站等中心节点或中心节点不参与资源分配的通信场景下，第一优先级的UE在需要占用资源进行数据发送时，在当前通信周期的SA子帧的内容中发送通告信号。第二优先级的UE从所述SA内容中接收所述通告信号，且在接收到所述通告信号后，确定在当前周期以后的m个通信周期不参与资源竞争或使用或以第一概率参与资源竞争，使第一优先级的UE有更大的几率竞争到资源，缓解竞争冲突的激烈程度。
所述第一优先级的UE在利用SA子帧发送所述通告信号时，可以新增有通告标识位的新SA格式来形成所述SA。新增有通告标识位的新SA格式中设置至少一个或多个比特来表示所述通告标识位。新SA格式和旧SA格式为区别在于：新SA格式中设置有ASFlag域。所述ASFlag域用于存储所述通告标识位。若第n通信周期所述第一优先级的UE不用发送数据，则第一优先级的UE进行SA子帧发送时，可依旧采用旧SA格式来承载SA信息形成SA子帧或采用新SA格式来形成所述SA子帧，但ASFlag域为0。所述新SA格式还可能包括PA域；所述PA域用于存储优先级，此处的优选级可以为UE属性的优先级和/或业务类型的优先级。在本申请实施例中，所述m的取值优先为1。
所述步骤S220还可为：在第n-m通信周期检测调度分配SA信息，确定发送所述SA信息的时频资源；根据发送所述SA信息的时频资源，确定所述通告信号的信息内容；其中，所述通告信号的信息内容与发送SA信息的时频资源具有映射关系。例如，所述通告信号为通告标识位，此时，利 用通告标识位还可以为由SA信息的发送时频资源来隐含指示；例如，利用特定时频资源发送的SA信息，表示所述通告标识位为1。此时，所述SA信息使用的SA格式可以为旧的SA格式。
设备实施例一：
如图6所示，本实施例提供一种用户设备，所述用户设备包括：
第一确定单元110，配置为确定用户设备的优先级；
发送单元120，配置为若所述用户设备的优先级为第一优先级且预定在第n通信周期有待发数据，在第n-m通信周期发送通告信号；
其中，所述n为不小于m的整数；m为大于或等于零的整数；
所述通告信号用于告知其他用户设备所述第一优先级的用户设备将参与第n通信周期的资源竞争或使用。
所述第一确定单元的具体结构因优先及级的确定方式的不同而不同，如从网络侧设备接收所述优先级，则所述第一确定单元110的具体结构可包括通信接口，如接收天线等能够接收数据的接口。如从UE内部的存储空间中进行所述优先级的读取，或UE的协议层配置优先级，则所述第一确定单元110可包括具有信息读取和解析功能的处理器等信息处理结构。所述处理器可包括应用处理器AP、中央处理器CPU、微处理器MCU、数字信号处理器DSP或可编程阵列PLC等具有信息处理功能的电子器件或电子器件的集合。
所述发送单元可包括发送天线等结构，具体用于发送所述通告信号。
所述通告信号告知第二优先级的UE，第一优先级的UE将参与第n通信周期的资源竞争或使用，这样收到第一优先级UE通告信号的第二优先级的UE可自行确定是否采取退避策略，不参与第n通信周期的资源竞争或使用，或以第一概率参与资源竞争。
本实施例所述的用户设备，具体可为手机、平板电脑等具有通信功能 的用户设备，具体如D2D UE或V2V UE等；在进行资源竞争时，能够优先优先级别高或业务优先级高的UE的资源分配，这样能够保证优先级高的UE能够有更大的几率竞争到资源进行数据传输，同时也能够降低资源竞争的激烈程度。
所述发送单元120发送所述通告信号AS的结构有多种，以下列举几种可选结构：
结构一：
所述发送单元120，配置为利用所述第n-m通信周期的同步子帧发送所述通告信号。具体的如，所述发送单元120，可用于形成通告信号；及利用所述同步子帧的时频资源发送所述通告信号。这样第二优先级的UE在接收到同步子帧时，就接收到了所述通告信号。再比如，所述同步子帧为用于发送同步序列的子帧；所述同步序列包括第一类同步序列和第二类同步序列；所述第一类同步序列不同于第二类同步序列；所述发送单元120，可用于利用同步子帧发送第一类同步序列；其中，所述第一类同步序列用于同步，同时还用于告知其他用户设备所述第一优先级的用户设备将参与第n通信周期的资源竞争。这样第二优先级的UE在接收到了所述第一类同步序列后将确定为第一优先级的UE将参与第n通信周期的资源竞争或使用。
结构二：
所述发送单元120，还可配置为将所述通告信号承载在第n-m通信周期的数据子帧的指定传输符号上发送所述通告信号。
结构三：

所述发送单元120，可配置为利用第n-m通信周期的SA子帧发送通告标识位。
结构四：所述发送单元120，配置为依据所述通告信号的信息内容，确 定发送SA信息的时频资源；利用确定的时频资源发送所述SA信息；其中，所述通告信号的信息内容与发送SA信息的时频资源具有映射关系。
这里的通告信号的信息内容可为前述通告标识位的信息内容，故在本实施例中还可以利用发送单元120的发送SA信息的时频资源来隐含指示通告信号的内容。例如，若通告标识位为1，则将SA信息在一个特定的时频资源上发送，这样作为接收端的UE在接收到所述SA信息时，确定通告信号的信息内容是：通告标识位为1。
综合上述，所述发送单元120可配置为利用同步子帧、数据子帧及SA子帧中任意一个来发送所述通告信号，在具体实现过程中，当然不局限于这些子帧来发送所述AS。
综合本实施例所述的用户设备能够用于实现方法实施例一所述的信息处理方法，具有能够缓和资源竞争及提高第一优先级的UE竞争到资源的概率。
设备实施例二：
如图7所示，本实施例提供一种用户设备，所述用户设备包括：
第二确定单元210，配置为确定用户设备的优先级；
检测单元220，配置为若所述用户设备的优先级为第二优先级，则在第n-m通信周期检测第一优先级的用户设备发送的通告信号；

所述检测单元220，优选为在第n通信周期有待发送数据时，在第n-m通信周期检测第一优先级的用户设备发送的通告信号，这样可以减少第二优先级的UE检测次数，减少第二优先级的UE的功耗。此处的n与方法实施例中一样，选取为不小于2的整数。所述通信周期的计数从1开始。
本实施例所述的第二确定单元210的具体结构与上一设备实施例中的 第一确定单元110的具体结构类似，在此就不重复了。

所述第三确定单元230配置为当确定出在第n通信周期有第一优先级的UE将参与资源竞争或使用，则确定自身是否参与第n通信周期的资源竞争或使用或延迟几个通信周期后参与资源竞争等与资源竞争相关的参数。
本实施例所述的第一优先级和第二优先级的相关描述可以参见方法实施例一或方法实施例二，在此就不重复了。
以下提供几种所述检测单元220检测所述通告信号的结构：
结构一：
所述检测单元220，可配置为检测所述第n-m通信周期的同步子帧；及从所述同步子帧上获取所述通告信号。如，所述检测单元220，可用于从所述同步子帧的指定时频资源上提取所述通告信号。再比如，所述检测单元220，还可用于提取所述同步子帧上的同步序列；判断所述同步序列是第一类同步序列还是第二类同步序列；及若所述同步序列为第一类同步序列则确定有接收到所述通告信号。
结构二：

结构四：所述检测单元220，配置为在第n-m通信周期检测调度分配SA信息，确定发送所述SA信息的时频资源；根据发送所述SA信息的时频资源，确定所述通告信号的信息内容；其中，所述通告信号的信息内容与发送SA信息的时频资源具有映射关系。在本实施例中所述检测单元220通过检测SA信息，确定出发送SA信息的时频资源，从而确定出通告信号的信息内容，例如，确定出通告信号对应的通告标识位的内容。
综合上述，本实施例所述的用户设备UE与设备实施例一中的用户设备为应用于同一通信场景下的UE，本实施例所述的UE能够用于实现方法实施例二所述的信息处理方法，能够降低资源竞争的激烈程度，提高第一优先级的UE竞争到资源的概率。
以下还提供两种所述第三确定单元230确定所述相关信息的结构；
结构一：
所述第三确定单元230，配置为依据所述通告信号，确定退出所述第n通信周期的资源竞争或使用。具体地如，当所述通告信号表明所述第一优先级的用户设备参与所述第n通信资源竞争或使用时，退出所述第n通信周期的资源竞争或使用。
结构二：
所述第三确定单元230，配置为当所述通告信号表明所述第一优先级的用户设备将参与所述第n通信周期资源竞争或使用时，以第一概率参与所述第n通信周期资源竞争；当未接收到所述通告信号或所述通告信号表明所述第一优先级的用户设备将不参与所述第n通信周期资源竞争或使用时，所述第二优先级的用户设备将以第二概率参与所述第n通信周期的资源竞争；所述第一概率小于所述第二概率。
以上两种结构都能快速简便的确定出在第n通信周期所述第二优先级 的UE如何参与资源竞争。
以下结合上述任一实施例，提供一个具体应用示例：
示例五：
如图8所示，在通信系统中，UE被分为了第一优先级的UE和第二优先级的UE，第一优先级高于第二优先级。
在第n-m通信周期：
第一优先级的UE确定在第n周期有数据待发送，将参与通信资源的竞争或使用，则在第n-m通信发送通告信号，如通过广播方式发送所述通告信号。
第二优先级的UE接收到所述通告信号后，确认第n通信周期将有第一优先级的UE参与第n通信周期的通信资源竞争或使用，将确定采取避让策略，退出第n通信周期的通信资源的竞争或使用。
在第n通信周期：
第一优先级的UE参与通信资源的竞争或使用，第二优先级的部分或全部UE不参与通信资源的竞争或使用。
