Description

非授权频段上的D2D通信方法、D2D通信装置、终端和基站
本申请要求于2016年8月15日提交中国专利局，申请号为201610672020.2、发明名称为“非授权频段上的D2D通信方法、D2D通信装置、终端和基站”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及通信技术领域，具体而言，涉及一种非授权频段上的D2D通信方法、一种非授权频段上的D2D通信装置、一种终端和一种基站。
背景技术
D2D（Device-to-Device，设备对设备）通信是3GPP Release-12引入的终端之间直接通信的技术，在传统的上下行通信链路（即uplink/downlink）基础上引入了副链路（sidelink）的概念。D2D通信技术已经完成了3GPP Rel-12和Rel-13的标准化，目前3GPP正在进行Rel-14的标准化。D2D通信技术在Release 12和Rel-13主要针对公共安全场景，从Rel-14开始针对商业场景进行标准化。此外，Rel-12到Rel-14的D2D技术主要针对授权频段，D2D通信相关的基站控制信令、终端间的同步信号（Sidelink Synchronization Signaling，简称SLSS）、调度分配信令（Scheduling Assignment，简称SA）和D2D数据的发送都不需要考虑来自非授权频段的干扰。
基于授权频段的D2D通信技术，尽管能够提供终端之间直接通信的能力，不占用宏基站的上下行传输资源。但是，D2D通信技术如果局限于授权频段，则存在较大的产业化和商业部署壁垒。在商业部署场景下，如果D2D通信与运营商部署的蜂窝网络采用同样的频段，则运营商会把D2D通信可能带来的干扰视为一个潜在的威胁。另一方面，D2D通信会旁路一部分运营商的流量，导致运营商的营收减少，对于比较重视流量经营的运营商来说，D2D通信技术在授权频段上部署缺乏成熟的商业模型。
现有的D2D通信技术一般是在D2D终端完成彼此发现后，在授权频段的资源上进行传输，并不支持在非授权频段进行D2D传输。因此，现有技术无法利用5G新的LTE传输技术（即在新的非授权频段上）进行D2D数据传输。
因此，如何能够确保D2D通信技术在非授权频谱上进行应用成为亟待解决的技术问题。
发明内容
本发明正是基于上述技术问题至少之一，提出了一种新的非授权频段上的D2D通信方案，实现了D2D通信机制在非授权频段上的应用。

在该技术方案中，通过接收基站指示的在非授权频段上进行D2D通信时所采用的频谱资源的粒度信息，使得基站能够综合非授权频段上的通信环境、终端能力等各方面的情况来指示终端在非授权频段上进行D2D通信，进而使得终端在非授权频段上需要传输D2D数据时，能够根据基站指示的粒度信息来获取传输资源并进行D2D数据的传输，实现了D2D通信机制在非授权频段上的应用。

具体实施方式
为了能够更清楚地理解本发明的上述目的、特征和优点，下面结合附图和具体实施方式对本发明进行进一步的详细描述。需要说明的是，在不冲突的情况下，本申请的实施例及实施例中的特征可以相互组合。
在下面的描述中阐述了很多具体细节以便于充分理解本发明，但是，本发明还可以采用其他不同于在此描述的其他方式来实施，因此，本发明的保护范围并不受下面公开的具体实施例的限制。
图1示出了根据本发明的第一个实施例的非授权频段上的D2D通信方法的示意流程图，该D2D通信方法适用于终端侧。
如图1所示，根据本发明的第一个实施例的非授权频段上的D2D通信方法，包括：
步骤S10，接收基站指示的在非授权频段上进行D2D通信时所采用的频谱资源的粒度信息。
在本发明的一个实施例中，步骤S10具体为：接收基站通过系统信息或专用信令指示的在非授权频段上进行D2D通信时所采用的频谱资源的粒度信息。
其中，基站指示的粒度信息可以是粗粒度信息或细粒度信息。粗粒度信息和细粒度信息的区别在于通信时占用的频谱带宽不同，即粗粒度信息表示的频谱带宽大于细粒度信息表示的频谱带宽。
步骤S12，判断在所述非授权频段上是否有D2D数据需要传输。
步骤S14，若判定在所述非授权频段上有D2D数据需要传输，则根据所述基站指示的所述粒度信息，获取在非授权频段上进行D2D通信的传输资源。
具体地，步骤S14在实现时有如下几种方式：
方式一：
步骤S14具体包括：在所述基站指示的粒度信息为第一粒度信息时，在指定非授权频段上进行信道检测；若在所述指定非授权频段上检测到信道空闲，则将所述指定非授权频段的全部带宽或部分带宽作为所述传输资源中的频域资源。
在该方式中，第一粒度信息可以是粗粒度信息，当基站指示第一粒度信息，且终端在指定非授权频段上检测到信道空闲时，则可以直接占用该非授权频段的全部或部分带宽来进行D2D通信。
方式二：
步骤S14具体包括：在所述基站指示的粒度信息为第二粒度信息时，根据所述基站预先配置的指定非授权频段的频段信息和资源信息，监听其它终端在所述指定非授权频段上的调度信息和/或用户数据的传输情况；根据监听到的所述其它终端在所述指定非授权频段上的调度信息和/或用户数据的传输情况，在所述指定非授权频段上选择进行D2D通信的传输资源。
在该方式中，第二粒度信息可以是细粒度信息，当基站指示第二粒度信息时，终端需要监听其它终端在指定非授权频段上的调度信息和/或用户数据的传输情况，以选取到合适的传输资源来进行D2D传输。
方式三：
步骤S14具体包括：在所述基站指示的粒度信息为第二粒度信息时，在指定非授权频段上进行信道检测；若在所述指定非授权频段上检测到信道繁忙，则根据所述基站预先配置的所述指定非授权频段的频段信息和资源信息，监听其它终端在所述指定非授权频段上的调度信息和/或用户数据的传输情况；根据监听到的所述其它终端在所述指定非授权频段上的调度信息和/或用户数据的传输情况，在所述指定非授权频段上选择进行D2D通信的传输资源。
在该方式中，当基站指示第二粒度信息时，终端可以先在整个非授权频段上进行信道检测，当检测到信道繁忙时，再进行更细粒度的检测，即监听其它终端在指定非授权频段上的调度信息和/或用户数据的传输情况，以选取到合适的传输资源来进行D2D传输。
方式四：
步骤S14具体包括：在所述基站指示的粒度信息为第二粒度信息时，向所述基站发送自身的位置信息；接收所述基站根据所述位置信息分配的在非授权频段上进行D2D通信的传输资源。
在该方式中，终端可以将自身的位置信息发送至基站，由基站辅助选择在非授权频段上进行D2D传输的资源，这样可以在非授权频段上实现空分复用。比如，位于不同位置的终端，基站在保证不会出现通信冲突的前提下，可以分配其使用相同的传输资源来进行D2D通信。
图1所示的非授权频段上的D2D通信方法，还包括：
步骤S16，基于获取到的所述传输资源，在非授权频段上传输所述D2D数据。
在图1所示的技术方案中，终端通过接收基站指示的在非授权频段上进行D2D通信时所采用的频谱资源的粒度信息，使得基站能够综合非授权频段上的通信环境、终端能力等各方面的情况来指示终端在非授权频段上进行D2D通信，进而使得终端在非授权频段上需要传输D2D数据时，能够根据基站指示的粒度信息来获取传输资源并进行D2D数据的传输，实现了D2D通信机制在非授权频段上的应用。
图2示出了根据本发明的第二个实施例的非授权频段上的D2D通信方法的示意流程图，该D2D通信方法适用于基站侧。
如图2所示，根据本发明的第二个实施例的非授权频段上的D2D通信方法，包括：
步骤S20，确定终端在非授权频段上进行D2D通信时所采用的频谱资源的粒度信息。
具体地，基站可以基于以下至少一个因素，确定终端在所述非授权频段上进行D2D通信时所采用的频谱资源的粒度信息：跨频谱的资源协调能力、终端的能力、对功耗的要求、对信令开销的要求。
步骤S22，向所述终端指示所述粒度信息，以使所述终端根据所述粒度信息，获取在非授权频段上进行D2D通信的传输资源。
其中，基站在向终端指示频谱资源的粒度信息时，一方面可以复用系统信息来进行指示，另一方面也可以通过定义新的专用信令来进行指示。
在该技术方案中，基站通过确定终端在非授权频段上进行D2D通信时所采用的频谱资源的粒度信息，使得基站能够综合非授权频段上的通信环境、终端能力等各方面的情况来指示终端在非授权频段上进行D2D通信，进而使得终端在非授权频段上需要传输D2D数据时，能够根据基站指示的粒度信息来获取传输资源并进行D2D数据的传输，实现了D2D通信机制在非授权频段上的应用。
进一步地，所述的非授权频段上的D2D通信方法还包括：获取邻小区内的终端在非授权频段上进行D2D通信时所采用的传输资源；根据所述邻小区内的终端在非授权频段上进行D2D通信时所采用的传输资源，确定本小区内的终端在进行D2D通信时应当采用的指定非授权频段；将所述指定非授权频段的信息通知给所述本小区内的终端，以使所述本小区内的终端在所述指定非授权频段上进行D2D通信。
在该技术方案中，通过根据邻小区内的终端在非授权频段上进行D2D通信时所采用的传输资源，确定本小区内的终端在进行D2D通信时应当采用的指定非授权频段，使得基站能够综合全局信息来选择本小区内的终端在进行D2D通信时应该采用的非授权频段，有利于实现负载均衡。
图1和图2分别从终端侧和基站侧阐述了如何实现D2D通信在非授权频段上的应用，以下结合图3从整体上进一步进行阐述：
如图3所示，根据本发明的第三个实施例的非授权频段上的D2D通信方法，包括：
步骤302，基站给终端配置非授权频段的访问粒度。
基站运行在授权频段上，所提供的宏小区被UE（User Equipment，用户设备，也即终端）选定为PCell（Primary Cell，主小区）。在PCell上，基站与D2D发送UE之间建立RRC（Radio Resource Control，无线资源控制）连接，同时也维护了MAC（Media Access Control，媒体访问控制）层逻辑信道来支持MAC信令传输。
基站配置的原则包括但不限于：网络部署中实现的跨频谱资源协调、UE的能力、对功耗和信令开销的考虑等。
其中，基站配置的访问粒度包括粗粒度和细粒度，粗粒度更适合于在非LTE协议使用的非授权频段，细粒度更适合于LTE协议使用的非授权频段。细粒度机制能够允许多个终端在非授权频段上进行的D2D传输实现基于时频资源的复用。
步骤304，终端判断是否有D2D数据发送需要，若是，则执行步骤306；否则，继续判断。
步骤306，终端检测到可用频段时，执行步骤308。
步骤308，判断基站配置的访问粒度是粗粒度还是细粒度，若是粗粒度，则执行步骤310；若是细粒度，则执行步骤312。
步骤310，使用LAA（License Assisted Access to Unlicensed Spectrum，允许辅助接入非授权频段）机制，使用全部或部分频段进行D2D传输。
其中，在基站的控制下，UE可以通过能量和/或功率检测的方法来实现与其他系统的LBT（Listen Before Talk，先听后说）操作，即进行信道检测，若检测到信道空闲，则UE直接使用部分或者整个频段来发送调度分配信令及数据。
这种机制适合UE使用一个非LTE协议的非授权频段，不需要UE去检测某个授权频段的UE发出的调度分配信令和数据，能够实现较粗粒度的资源使用。
步骤312，进行SA解析，使用部分时频资源进行D2D传输。
具体的实现可以采用基于调度模式的D2D通信机制，支持PCell调度功能的宏基站需要预先配置非授权频段的频段及其资源信息。UE可以监听其他UE的调度分配信令和数据的传输实现D2D通信之前的LBT检测。其中，这种监听机制需要UE能够解析在非授权频段上的协议，从而鉴别是否可以进行D2D传输。并且这种机制需要UE解析某个授权频段上的协议，来选择合适的时频资源进行D2D数据发送。
可选地，如果D2D发送UE能够向基站报告其具体位置信息，则宏基站可以根据发送UE的位置信息，选择合适的时频资源来进行调度。比如，位于不同位置的D2D发送UE，可以使用相同的时频资源来进行D2D数据的传输，这样可以在非授权频段上进一步实现空分复用。
需要注意的是，在上述步骤310中，如果UE通过LBT机制检测到某个非授权频段上的信道繁忙，但是仍然希望通过该频段进行D2D传输，则可以按照步骤312所描述的进行细粒度的频谱资源访问和使用。
在本发明的一个具体实施例中，如图4所示，基站运行在授权频段，PCell支持非授权频段上的D2D通信的调度，基站可以调度终端402来获取在非授权频段上进行D2D传输的时频资源，进而终端402能够通过获取的时频资源与终端404进行D2D通信。
为了减少大量终端集中在一个非授权频谱上进行D2D传输造成冲突的问题，PCell需要维护的信息包括多个所连接的UE在其他非授权频谱上进行D2D传输的资源分配信息。
同时，PCell也可能需要维护其他连接在邻小区上的UE在非授权频段上进行传输的D2D资源信息。通过PCell所维护的全局信息，PCell能够对D2D发送终端是通过非授权频段还是授权频段进行传输进行决策。并且当在非授权频段上进行传输的D2D终端数量较多、密度较大时，PCell可以调度UE在其他的非授权频段上进行D2D通信，以实现负载的调解和均衡。
