本发明涉及无线通信技术领域。更具体地，本发明涉及用于设备间通信的方法以及基站和用户设备。
背景技术
现代无线移动通信系统呈现出两个显著特点，一是宽带高速率，比如第四代无线移动通信系统的带宽可达100MHz，下行速率高达1Gbps；二是移动互联，推动了移动上网、手机视频点播、在线导航等新兴业务。这两个特点对无线移动通信技术提出了较高要求，主要有：超高速率无线传输、区域间干扰抑制、移动中可靠传输信号、分布式/集中式信号处理等等。在未来的增强第四代(4G)及第五代(5G)无线移动通信系统中，为了满足上述发展需求，各种相应的关键技术开始被提出和论证，值得本领域的研究人员广泛关注。
对于增强的第四代无线移动通信系统，大致有以下几点发展需求：
-更高的无线宽带速率，且重点优化局部的小区热点区域；
-进一步提高用户体验，特别需要优化小区边界区域的通信服务；
-考虑到可用频谱不可能有1000倍的扩展，故需要继续研究能够提高频谱利用效率的新技术；
-高频段的频谱(5GHz，甚至更高)必将投入使用，以获得较大的通信带宽；
-现有网络(2G/3G/4G，WLAN，WiMax等)的协同工作，以分担数据流量；
-针对不同业务、应用和服务特定优化；
-加强系统支持大规模机器通信的能力；
-灵活、智能且廉价的网络规划与布网；
-设计方案以节省网络的用电量和用户设备的电池消耗。
为了实现上述发展需求，国际第三代伙伴计划(3GPP)组织在第58次全会上讨论并通过了将设备到设备(D2D)通信技术作为增强的第四代无线移动通信系统的关键技术。
D2D技术可以实现本地通信或对等的点对点通信，而无需接入核心网络，采用D2D技术的传输方式，在减轻基站负载和延长移动终端电池的使用时间上都有十分积极的作用。通常根据实现D2D传输的用户设备(以下称为D2D用户设备)所处的场景是否有宏基站的覆盖，可以将D2D用户设备的场景划分为：有网络覆盖下、无网络覆盖下以及部分网络覆盖，其中部分网络覆盖的场景是指，包含有网络覆盖和无网络覆盖的D2D用户设备的情况。
目前针对D2D通信，特别是基站覆盖下的D2D通信，3GPP定义了利用物理下行控制信道(PDCCH)和增强的物理下行控制信道(EPDCCH)来传输D2D调度分配(SA)和D2D数据对应的D2D授权信息(Grant)，但如何采用现有的PDCCH和EPDCCH对D2D调度分配(SA)和D2D数据进行相应的调度，特别在哪些时频资源位置上传输D2D调度分配(SA)和D2D数据，目前还没有具体的设计。
因此，需要新的来自基站的指示或预定义的方式，以解决采用哪些时频资源位置来传输D2D调度分配(SA)及D2D数据。
