具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参考图2，图2是本发明实施例提供的一种D2D多载波聚合的载波集选取方法的流程示意图。如图所示，本发明实施例中的方法包括：
S201，基站接收终端发送的汇报信息，所述汇报信息包括所述终端经测量后满足上报条件的多个载波。
具体实现中，首先，终端可以向所述基站发送设备对设备的通信请求，其中，通信请求中包含期待的频点信息，如果终端能够支持广播式的CA或者单播式的CA，通信请求也可以包括支持广播式的CA或单播式的CA的指示。然后，基站接收到通信请求之后，配置载波集测量的载频信息和上报条件，适用于空闲态的UE和/或连接态的UE，其中，载频信息用于指示终端测量载频的范围，包括单播式的载频测量对象或/和广播式的载频测量对象；上报条件可以包括信号瞬时门限值、一段时间内的测量信号的加权平均门限值等等。需要说明的是，门限值越低越适合发送D2D CA数据，因此对于高于特定门限值的载波可以过滤掉。其次，基站向终端发送的预先配置的载波集测量的载频信息以及上报条件，进一步的，基站可以通过系统信息块(System information block，SIB)广播一定区域的D2D载频信息及其各个载频的上报门限制。最后，终端接收到载波集测量的载频信息以及上报条件之后，确定所述载频信息中满足所述上报条件的多个载波，并将满足上报条件的多个载波上报给基站。
可选的，终端可以预先配置载波集测量的载频信息和上报条件，其中，载频信息为与位置相关的可用D2D载频信息。在终端存在D2D通信需求时，确定在所述终端中预先配置的载波集测量的载频信息中满足上报条件的多个载波，并将满足上报条件的多个载波上报给基站。
需要说明的是，如果基站已广播预先配置的载波集测量的载频信息，则优先选择基站广播的载频信息进行测量，如果基站未广播预先配置的载波集测量的载频信息，则可以选择终端自身配置的载频信息进行测量。
S202，所述基站根据所述多个载波的资源状况，选取用于所述终端进行设备对设备通信的载波聚合的载波集。
具体实现中，资源状况可以包括载波的使用情况、终端的地理位置等等。设备对设备的载波聚合的载波集为配置给收发双方UE进行通信的可用载波，载波集可以包括单播式的面向连接的载波聚合和/或广播式的面向无连接的载波聚合。如果终端支持广播式的载波聚合，则可以选取广播式的面向无连接的载波聚合，如果终端支持单播式的载波聚合，则可以选取单播式的面向连接的载波聚合。
对于单播式的面向连接的载波聚合，所述基站可以获取所述终端进行设备对设备通信的配对信息；所述基站根据所述配对信息，选取用于所述终端进行设备对设备通信配对的载波集。进一步的，可以根据所述终端的地理位置或所述终端的设备对设备的发现结果，确定所述终端进行设备对设备通信的配对信息。
对于广播式的面向无连接的载波聚合，基站不需要对D2D通信进行配对，发送终端可以在基站分配的多个载波上广播数据，而不针对于特定接收终端，接收终端需要在基站分配的多个载波上监听数据。这种方式对标准化影响最小，但是存在一个限制，即最适合于D2D通信的专用载频，如果载频上有DL和UL业务则不适合采用此种方式进行通信。
可选的，在所述基站根据所述多个载波的资源状况，选取用于所述终端进行设备对设备通信的载波聚合的载波集之后，所述基站可以向所述终端发送指示信息，所述指示信息包括选取的所述载波集，所述终端接收到所述指示信息之后，可以在选取的设备对设备通信配对的载波集上调度数据；或在选取的所述载波集上广播数据。
需要说明的是，在设备对设备载波聚合通信开始之后，终端并不是每次在基站分配的所有载波上调度数据，而是从基站分配的所有载波中选取部分载波调度数据。
在本发明实施例中，基站首先接收终端发送的汇报信息，所述汇报信息包括所述终端经测量后满足上报条件的多个载波；然后根据所述多个载波的资源状况，选取用于所述终端进行设备对设备通信的载波聚合的载波集，从而解决D2D在多个载波上以载波聚合方式进行通信时的载波集选取问题，提高通信质 量。
请参考图3，图3是本发明另一实施例提供的一种D2D多载波聚合的载波集选取方法的流程示意图。如图所示，本发明实施例中的方法包括：

进一步的，基站可以通过系统信息块(System information block，SIB)广播一定区域的D2D载频信息及其各个载频的上报门限制。
S303，终端确定所述载频信息中满足所述上报条件的多个载波。
可选的，终端可以预先配置载波集测量的载频信息和上报条件，其中，载频信息为与位置相关的可用D2D载频信息。在终端存在D2D通信需求时，确定在所述终端中预先配置的载波集测量的载频信息中满足上报条件的多个载波。
需要说明的是，如果基站已广播预先配置的载波集测量的载频信息，则优先选择基站广播的载频信息进行测量，如果基站未广播预先配置的载波集测量的载频信息，则可以选择终端自身配置的载频信息进行测量。
S304，终端向基站发送汇报信息，所述汇报信息包括所述终端经测量后满足上报条件的多个载波。
S305，基站根据所述多个载波的资源状况，选取用于所述终端进行设备对设备通信的载波聚合的载波集。
具体实现中，资源状况可以包括载波的使用情况、终端的地理位置等等。设备对设备的载波聚合的载波集为配置给收发双方UE进行通信的可用载波，载 波集可以包括单播式的面向连接的载波聚合和/或广播式的面向无连接的载波聚合。如果终端支持广播式的载波聚合，则可以选取广播式的面向无连接的载波聚合，如果终端支持单播式的载波聚合，则可以选取单播式的面向连接的载波聚合。
对于单播式的面向连接的载波聚合，所述基站可以获取所述终端进行设备对设备通信的配对信息；所述基站根据所述配对信息，选取用于所述终端进行设备对设备通信配对的载波集。进一步的，可以根据所述终端的地理位置或所述终端的设备对设备的发现结果，确定所述终端进行设备对设备通信的配对信息。
对于广播式的面向无连接的载波聚合，基站不需要对D2D通信进行配对，发送终端可以在基站分配的多个载波上广播数据，而不针对于特定接收终端，接收终端需要在基站分配的多个载波上监听数据。这种方式对标准化影响最小，但是存在一个限制，即最适合于D2D通信的专用载频，如果载频上有DL和UL业务则不适合采用此种方式进行通信。
