基于多载波的D2D资源配置方法、装置、基站和终端 技术领域
本发明涉及通信技术领域，具体而言，涉及一种基于多载波的D2D资源配置方法、一种基于多载波的D2D资源配置装置、一种基站和一种终端。
背景技术
现有技术即3GPP Rel-12仅仅讨论了单个载波上的D2D(Device-to-Device，设备对设备)发现消息的发送机制，不支持多个载波上的D2D发现消息的发送机制。因此，基于目前的技术，无法在多载波环境下实现高效率的D2D发现控制机制。同时，从3GPP Rel-9起已经定义了载波聚合的机制，但是在载波聚合机制下如何支持在SCell(Secondary Cell，辅小区)上的D2D发现机制尚无公开的方案。因此，基于目前的技术，无法实现多个载波在支持D2D发现方面的负载均衡，并且也无法利用载波聚合的机制实现跨小区的D2D发现控制机制。
因此，如何能够在多载波环境下实现D2D发现过程的负载均衡，并且实现跨小区的D2D发现控制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，提出了一种新的基于多载波的D2D资源配置方案，可以通过主小区基站的调度实现跨小区的D2D发现机制，保证了在多个载波上的D2D发现机制的负载均衡，并且实现了高效率的D2D发现控制机制，避免了在一个载波上出现资源被过多占用而导致D2D发现机制效率较低的问题。
有鉴于此，本发明提出了一种基于多载波的D2D资源配置方法，适用于为终端提供服务的主小区基站，包括：所述主小区基站获取所述终端 在多个载波上的射频收发能力，并判断是否与所述终端的辅小区基站之间进行了D2D发现资源信息的协商交换；根据所述射频收发能力和所述辅小区基站的配置信息确定是否能够调度所述终端进行多载波的D2D发现；在确定能够调度所述终端进行多载波的D2D发现时，并在判定与所述辅小区基站之间进行了D2D发现资源信息的协商交换时，根据所述辅小区基站的D2D发现资源向所述终端配置用于D2D发现的传输资源。其中，射频收发能力优选为终端在多个载波上进行D2D发现信号的发送和接收的射频收发能力。
在该技术方案中，主小区基站通过在确定能够调度终端进行多载波的D2D发现时，以及在确定与辅小区基站之间进行了D2D发现资源信息的协商交换时，根据辅小区基站的D2D发现资源配置向终端配置D2D发现资源，使得在向终端配置D2D发现的传输资源时，能够通过主小区基站的调度实现跨小区的D2D发现机制，保证了在多个载波上的D2D发现机制的负载均衡，有利于实现高效率的D2D发现控制机制，避免了在一个载波上出现资源被过多占用而导致D2D发现机制效率较低的问题。从信令开销的角度，可以避免终端与主小区基站小区断开RRC连接，与辅小区基站建立RRC连接来获取辅小区的D2D发现的调度模式的资源。

在该技术方案中，通过在检测到向终端提供服务的辅小区基站发生变化时，通过RRC信令将变化后的辅小区基站的信息发送至主小区基站，使得主小区基站能够重新确定是否能够根据变化后的辅小区基站的D2D发现资源向终端配置用于D2D发现的传输资源，以确保即便向终端提供服务的辅小区基站发生变化，也能够获得最新的D2D发现信号传输资源。
图4示出了根据本发明的一个实施例的适用于终端的基于多载波的D2D资源配置装置的示意框图。
如图4所示，根据本发明的一个实施例的适用于终端的基于多载波的D2D资源配置装置400，包括：发送单元402，用于向主小区基站发送在多个载波上的射频收发能力，以供所述主小区基站确定是否能够调度所述终端进行多载波的D2D发现；接收单元404，用于接收所述主小区基站根据所述终端的辅小区基站的D2D发现资源向所述终端配置的用于D2D发 现的传输资源；处理单元406，用于根据所述用于D2D发现的传输资源执行D2D发现过程；其中，所述主小区基站在根据所述射频收发能力和所述辅小区基站的配置信息确定能够调度所述终端进行多载波的D2D发现时，并在与所述辅小区基站之间进行了D2D发现资源信息的协商交换时，向所述终端配置所述用于D2D发现的传输资源。
在该技术方案中，终端通过向主小区基站发送在多个载波上的射频收发能力，使得主小区基站可以确定是否能够调度终端进行多载波的D2D发现，并在确定能够调度终端进行多载波的D2D发现时，以及在确定与辅小区基站之间进行了D2D发现资源信息的协商交换时，通过辅小区基站的D2D发现资源向终端配置D2D发现资源，使得在向终端配置D2D发现的传输资源时，能够通过主小区基站的调度实现跨小区的D2D发现机制，保证了在多个载波上的D2D发现机制的负载均衡，有利于实现高效率的D2D发现控制机制，避免了在一个载波上出现资源被过多占用而导致D2D发现机制效率较低的问题。
在上述技术方案中，优选地，所述发送单元402具体用于：将具有的射频链路的数量和/或是否支持同时接收发送的能力发送至所述主小区基站。
在上述技术方案中，优选地，还包括：检测单元408，用于检测向所述终端提供服务的辅小区基站是否发生变化；所述发送单元402还用于，在所述检测单元检测到向所述终端提供服务的辅小区基站发生变化时，通过RRC信令将变化后的辅小区基站的信息发送至所述主小区基站。
在该技术方案中，通过在检测到向终端提供服务的辅小区基站发生变化时，通过RRC信令将变化后的辅小区基站的信息发送至主小区基站，使得主小区基站能够重新确定是否能够根据变化后的辅小区基站的D2D发现资源向终端配置用于D2D发现的传输资源，以确保即便向终端提供服务的辅小区基站发生变化，也能够获得最新的D2D发现信号传输资源。
本发明还提出了一种终端(图中未示出)，包括：如图4中所示的基于多载波的D2D资源配置装置400。
以下结合图5详细说明本发明的技术方案。
本发明的技术方案主要是：当UE(User Equipment，用户设备)处于连接状态，并与PCell(Primary Cell，主小区)建立了RRC(Radio Resource Control，无线资源控制协议)连接的情况下，如果PCell与SCell之间已经进行了D2D发现资源信息的协同，且UE的射频链路(RF chain)能够支持同时接入PCell和SCell所在的两个载波，则UE可以不断开与PCell之间的RRC连接，直接根据从PCell得到的SCell的D2D发现资源配置，在SCell的载波上进行D2D发现消息的发送。具体处理流程如图5所示：
如图5所示，根据本发明的另一个实施例的基于多载波的D2D资源配置方法，包括：
步骤502，PCell与SCell之间进行D2D发现资源信息的协同交换。
其中，协同的具体含义是UE在PCell/当前载波是否具有另一个载波的D2D发现资源控制以及小区间是否进行了D2D发现资源信息的交互。
步骤504，UE射频能力的上报。
为了使得PCell能够确定是否可以跨载波调度D2D发现资源给UE，PCell需要得知UE的射频收发能力，具体来说：
UE是否拥有两个射频链路，以便同时支持在两个载波上的上下行和D2D发现业务；
若UE是单射频链路，则UE能否以TDM(时分复用)的方式支持在两个小区进行上下行收发和D2D发现业务。
同时，PCell还需要知道SCell的配置信息，即SCell是否能够提供D2D发现资源，若SCell可以提供，则PCell确定能够对UE进行多载波的D2D发现资源的调度；若SCell由于负载的原因无法提供D2D发现资源，则PCell确定不对UE进行多载波的D2D发现资源的调度。
步骤506，PCell对终端进行测量配置。
步骤508，终端向PCell上报测量报告。
步骤510，PCell通知终端选择SCell的D2D发现资源对终端的D2D传输资源进行调度。
具体地，在确定能够根据某个SCell的D2D发现资源向终端配置用于D2D发现的传输资源时，可以通过PCell来控制UE优先采用该SCell载波上的调度模式的D2D发现资源进行D2D发现，即由PCell完成SCell上的D2D发现资源的调度。当然，UE也可以与PCell断开RRC连接，并与SCell建立RRC连接，以由SCell直接进行D2D发现资源的调度。
本发明上述实施例的技术方案可以实现多个载波上的D2D发现的负载均衡，避免出现某一个载波的资源被过多占用的问题；同时，本发明的技术方案可以实现在CA(Carrier Aggregation，载波聚合)的框架下对跨载波资源的高效率控制。
以上结合附图详细说明了本发明的技术方案，考虑到基于目前的技术，无法实现多个载波在支持D2D发现方面的负载均衡，并且也无法利用载波聚合的机制实现跨小区的D2D发现控制机制。因此，本发明提出了一种新的基于多载波的D2D资源配置方案，可以通过主小区基站的调度实现跨小区的D2D发现机制，保证了在多个载波上的D2D发现机制的负载均衡，并且实现了高效率的D2D发现控制机制，避免了在一个载波上出现资源被过多占用而导致D2D发现机制效率较低的问题。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
