Description

一种D2D资源配置信息的传输方法及设备
本申请要求在2013年11月01日提交中国专利局、申请号为201310536038.6、发明名称为“一种D2D资源配置信息的传输方法及设备”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,尤其涉及一种设备到设备(Device-to-Device,D2D)资源配置信息的传输方法及设备。
背景技术
D2D,即终端直通技术,是指邻近的终端可以在近距离范围内通过直连链路进行数据传输的方式,不需要通过中心节点(即基站)进行转发。
在D2D的研究中,主要考虑的场景有四种,各个场景可以组合出现。这四种场景分别是:
进行D2D通信的用户设备(UE,又称终端)1和UE2均在网络覆盖外(Out of Coverage);
进行D2D通信的UE1和UE2,其中,UE1在网络覆盖内(In Coverage),UE2在网络覆盖外;
进行D2D通信的UE1和UE2均在同一小区的网络覆盖内;
进行D2D通信的UE1和UE2在不同小区的网络覆盖内。
在D2D的通信中,除了UE之间的一对一的通信方式之外,典型的应用场景还包括D2D UE之间进行群组/广播通信,其实现的方式可以如下:
一个UE通过单次传输给一个通信群组里的所有UE发送相同数据(群组通信);
一个UE通过单次传输给授权的所有附近的UE发送相同数据(广播通信);
这种场景可以用于公共安全应用中的消防、救援和反恐等。
在D2D传输中,目前主要存在两种资源分配或者资源占用的方法:
基于竞争的资源分配方法,各个D2D UE按照相同的原则竞争资源传输。这种场景主要用于非中心节点进行调度情况下,各个D2D UE之间仍然可以通信,从而保证通信的鲁棒性。
基于调度的资源分配方法,D2D UE传输的资源是通过演进型节点(eNB)或者具有调度能力的簇头(Cluster Head,CH)调度,这种方式可以有效的提高资源的利用率。
考虑到在部分D2D UE在网络覆盖内的场景,例如UE1位于网络覆盖内,其D2D的传输可以是通过演进型基站(eNB)调度,但是对于UE2来说,其位于eNB的覆盖外,因此UE2遵循的是竞争的方式进行传输。UE2通过竞争获取的资源可能与eNB为UE1调度的资源发生冲突。
发明内容
本发明的目的是提供一种D2D资源配置信息的传输方法及设备,以解决部分D2D UE在网络覆盖内的场景下,网络覆盖外的D2D UE竞争获得的传输资源与网络覆盖内的D2D UE通过调度获得的传输资源冲突的问题。

本发明实施例中,D2D超帧由其时长内的D2D子帧构成。
现有技术中,网络覆盖外的D2D UE竞争获得的传输资源与网络覆盖内的D2D UE通过调度获得的传输资源发生冲突,是因为没有为D2D UE预留专门用于通过竞争方式获取传输资源的竞争区域,且网络覆盖外的D2D UE无法获知哪些资源可以通过竞争获得。本发明实施例提供的方法,D2D终端接收到D2D资源配置信息后,根据该D2D资源配置信息生成新的D2D资源配置信息并发送。划分了竞争区域,且D2D资源配置信息中包括竞争区域的资源位置信息,使得D2D终端(尤其是网络覆盖外的D2D终端)能够获知竞争区域所在的资源位置,从而可以通过竞争获取竞争区域的资源位置信息,而不会与其他D2D终端通过调度获得的传输资源发生冲突。

具体实施方式
下面将结合附图,对本发明实施例提供的技术方案进行详细说明。
本发明实施例提供的一种D2D资源配置信息在D2D终端侧的传输方法如图1所示,具体包括如下操作:
步骤100、D2D终端接收D2D资源配置信息,该D2D资源配置信息指示了D2D超帧的结构,至少包括D2D超帧中竞争区域的资源位置信息。
本发明实施例中,D2D超帧由其时长内的D2D子帧构成。假设D2D超帧的时长为100 毫秒(ms)。如果由网络侧设备分配D2D资源,且D2D子帧被配置为10ms周期、子帧3和子帧8,那么,一个D2D超帧就由100ms内的子帧3和子帧8(共20个D2D子帧)构成。如果由作为簇头的D2D终端分配D2D资源,则每个子帧均为D2D子帧,一个D2D超帧由100ms内的100个子帧构成。
竞争区域占用D2D超帧中的部分资源。D2D终端通过竞争方式获取竞争区域的传输资源。多个D2D终端采用相同的准则竞争传输资源,例如:基于能量检测的方式占用资源,或者载波侦听多点接入/冲突避免(Carrier Sense Multiple Access with Collision Avoidance,CSMA/CA)的方式占用资源。
竞争区域与D2D超帧中划分的其他区域可以采用时分复用(TDM)、频分复用(FDM)、或者时分、频分混合复用。如果采用时分复用,竞争区域的资源位置信息可以是竞争区域占用的D2D子帧的信息;如果采用频分复用,竞争区域的资源位置信息可以是竞争区域占用的物理资源块(PRB)的信息。
步骤110、该D2D终端根据接收到的D2D资源配置信息,生成新的D2D资源配置信息,生成的D2D资源配置信息包括D2D超帧中竞争区域的资源位置信息。
如果D2D终端在预定时间内接收到一个D2D资源配置信息,那么,生成的D2D资源配置信息中D2D超帧中竞争区域的资源位置信息包括接收到的D2D资源配置信息中包括的D2D超帧中竞争区域的资源位置信息。
如果D2D终端在预定时间内接收到多个D2D资源配置信息,那么,生成的D2D资源配置信息包括的D2D超帧中竞争区域的资源位置信息是根据D2D终端在所述预定时间内接收到的所有D2D资源配置信息包括的D2D超帧中竞争区域的资源位置信息确定的。
例如,如果在预定时间内接收到2个D2D资源配置信息,一个D2D资源配置信息中指示竞争区域占用D2D超帧的第1~3个D2D子帧,另一个D2D资源配置信息中指示竞争区域占用D2D超帧的第1~5个D2D子帧,那么,生成的D2D资源配置信息包括的D2D超帧中竞争区域的资源位置信息可以是指示占用D2D超帧的第1~3个D2D子帧的信息。又例如,如果在预定时间内接收到2个D2D资源配置信息,一个D2D资源配置信息中指示竞争区域占用D2D超帧的第1~3个D2D子帧,并指示第4~6个D2D子帧被划分为其他区域,另一个D2D资源配置信息中指示竞争区域占用D2D超帧的第4~6个D2D子帧,那么,生成的D2D资源配置信息包括的D2D超帧中竞争区域的资源位置信息可以是指示占用D2D超帧的第1~3个D2D子帧的信息。
应当指出的是,D2D终端生成的D2D资源配置信息中携带的参数还可以有其他确定方式,具体根据实际应用场景需求而定,本发明不作限定。
步骤120、该D2D终端获得传输资源后,通过获得的传输资源发送生成的D2D资源配置信息。
本发明实施例提供的方法,D2D终端接收到D2D资源配置信息后,根据该D2D资源配置信息生成新的D2D资源配置信息并发送。D2D资源配置信息中包括竞争区域的资源位置信息,使得D2D终端能够获知竞争区域所在的资源位置,从而可以通过竞争获取竞争区域的资源位置信息,而不会与通过调度获得的传输资源发生冲突。
较佳地,D2D终端通过获得的传输资源发送生成的D2D资源配置信息的具体实现方式可以是:在需要进行数据发送时,该D2D终端通过获取的传输资源发送生成的D2D资源配置信息和待发送的数据。
基于上述任一实施例,D2D资源配置信息还可以包括以下任一参数或组合:
(一)、如果D2D超帧的时长不是预先约定的,那么,网络侧设备或者作为簇头的D2D终端在确定D2D超帧结构时,还确定D2D超帧的时长。相应的,D2D终端接收到的D2D资源配置信息还可以包括:D2D超帧的时长。生成的D2D资源配置信息还可以包括:D2D超帧的时长。
如果不同网络侧设备和/或作为簇头的D2D终端确定的D2D超帧的时长不同,则可以通过D2D资源配置信息的传播或者其他方式获取其他网络侧设备或作为簇头的D2D终端配置的D2D超帧的时长,并通过协商的方式统一D2D超帧的时长。
D2D终端接收到的D2D资源配置信息还可以包括:D2D超帧的时长。
(二)、网络侧设备或作为簇头的D2D设备配置的D2D超帧结构中,可以仅包括竞争区域用作D2D终端的传输资源。进一步的,还可以在D2D超帧结构中划分非竞争区域,非竞争区域的资源用于D2D终端采用调度方式传输数据。具体可以根据管理下的D2D终端的资源调度请求来确定是否预留非竞争区域,以及非竞争区域的大小。对于网络侧设备,优选的D2D超帧结构划分方式是包含非竞争区域。
其中,如图2所示,竞争区域与非竞争区域采用TDM的方式划分。
如图3所示,竞争区域与非竞争区域采用FDM的方式划分。
当D2D超帧结构包括非竞争区域,那么,D2D终端接收到的D2D资源配置信息还包括:D2D超帧中非竞争区域的资源位置信息;生成的D2D资源配置信息还包括:D2D超帧中非竞争区域的资源位置信息。
其中,如果预定时间内收到一个D2D资源配置信息,那么,生成的D2D资源配置信息包括的D2D超帧中非竞争区域的资源位置信息可以是接收到的D2D资源配置信息包括的D2D超帧中非竞争区域的资源位置信息。如果预定时间内收到多个D2D资源配置信息,那么,生成的D2D资源配置信息包括的D2D超帧中非竞争区域的资源位置信息是根据预定时间内接收到的所有D2D资源配置信息包括的D2D超帧中非竞争区域的资源位置信息确定的。例如,预定时间内接收到2个D2D资源配置信息,假设一个D2D资源配置信息中包括的D2D超帧中非竞争区域的资源位置信息指示其占用D2D超帧中的最后10个D2D 子帧,另一个D2D资源配置信息中包括的D2D超帧中非竞争区域的资源位置信息指示其占用D2D超帧中的最后12个D2D子帧。那么,生成的D2D资源配置信息中包括的D2D超帧中非竞争区域的资源位置信息可以是指示占用D2D超帧最后12个D2D子帧的信息。又例如,预定时间内接收到2个D2D资源配置信息,假设一个D2D资源配置信息中包括的D2D超帧中非竞争区域的资源位置信息指示其占用D2D超帧中的最后10个D2D子帧,另一个D2D资源配置信息中包括的D2D超帧中非竞争区域的资源位置信息指示其占用D2D超帧中的倒数第11~倒数第30个D2D子帧。那么,生成的D2D资源配置信息中包括的D2D超帧中非竞争区域的资源位置信息可以是指示占用D2D超帧最后30个D2D子帧的信息。
如果D2D资源配置信息包括D2D超帧中非竞争区域的资源位置信息,那么,第(三)种情况、D2D终端接收到的D2D资源配置信息还可以包括:非竞争区域的层数;生成的D2D资源配置信息还可以包括:非竞争区域的层数,该层数为D2D终端接收到的D2D资源配置信息中非竞争区域的层数加1的取值结果和预定的最大层数阈值中的最小值。
如果预定时间内接收到1个D2D资源配置信息,生成的D2D资源配置信息中的层数为接收到的这个D2D资源配置信息中非竞争区域的层数加1的取值结果和预定的最大层数阈值中的最小值。如果预定时间内接收到多个D2D资源配置信息,生成的D2D资源配置信息中的层数为接收到的多个D2D资源配置信息中非竞争区域的层数分别加1的取值结果以及预定的最大层数阈值中的最小值。
非竞争区域的层数达到最大层数阈值,则表示该非竞争区域距离分配D2D资源的网络侧设备或簇头较远,那么,占用该非竞争区域用于竞争传输资源,不会对调度传输产生干扰,或者产生的干扰在允许范围内。因此,如果接收到的D2D资源配置信息中非竞争区域的层数达到最大层数阈值,可以将该非竞争区域作为竞争区域。相应的,还可以将该非竞争区域的资源位置信息作为生成的D2D资源配置信息包括的竞争区域的资源位置信息。
进一步的,如果预定时间内接收到的多个D2D资源配置信息中的非竞争区域占用的资源位置不同,为了使得层数的指示更加精准,可以预先规定非竞争区域占用的最小资源粒度,并用最小资源粒度为单位指示非竞争区域的层数。具体的,非竞争区域内的信道划分方式可以是TDM划分,可以是FDM划分,还可以是TDM+FDM的划分方式。
以TDM划分方式为例,假设预定时间内接收到2个D2D资源配置信息。其中一个D2D资源配置信息包括的D2D超帧中的非竞争区域占用D2D超帧的最后10个D2D子帧,另一个D2D资源配置信息包括的D2D超帧中的非竞争区域占用D2D超帧的最后12个D2D子帧。这两个D2D超帧的时长相同,第一个非竞争区域的层数为1,第二个非竞争区域的层数为2,最大层数阈值为3,非竞争区域占用的最小资源粒度为2个D2D子帧。那么,生成的D2D资源配置信息包括的D2D子帧中非竞争区域的层数以最小资源粒度为单位进 行指示。例如,倒数第11和12个D2D子帧对应的非竞争区域的层数为3;最后10个D2D子帧对应的非竞争区域的层数为2,或者最后10个D2D子帧对应的非竞争区域中每2个D2D子帧对应一个层数2。
以FDM划分方式为例,假设预定时间内接收到2个D2D资源配置信息。其中一个D2D资源配置信息包括的D2D超帧中的非竞争区域占用D2D超帧的编号为0~9的PRB,另一个D2D资源配置信息包括的D2D超帧中的非竞争区域占用D2D超帧的编号为0~11的PRB。第一个非竞争区域的层数为1,第二个非竞争区域的层数为2,最大层数阈值为3,非竞争区域占用的最小资源粒度为2个PRB。那么,生成的D2D资源配置信息包括的D2D子帧中非竞争区域的层数以最小资源粒度为单位进行指示。例如,编号为10和11的PRB对应的非竞争区域的层数为3;编号为0~9的PRB对应的非竞争区域的层数为2,或者编号为0~9的PRB对应的非竞争区域中每2个PRB对应一个层数2。
另外,生成的D2D资源配置信息中的层数可以根据一个或多个D2D超帧周期内接收到的D2D资源配置信息进行更新。
如果D2D资源配置信息包括D2D超帧中非竞争区域的资源位置信息,那么,第(四)种情况、D2D终端接收到的D2D资源配置信息还可以包括:非竞争区域的子信道划分信息;生成的D2D资源配置信息还可以包括:非竞争区域的子信道划分信息。
D2D超帧中非竞争区域可以采用时分复用,如图4所示,也可以采用频分复用,如图5所示,还可以采用时分、频分混合复用,如图6所示。
如果D2D超帧中非竞争区域内的信道采用频分复用,则子信道以PRB为单位进行划分。如果D2D超帧中非竞争区域内的信道采用时分复用,则子信道以D2D子帧为单位进行划分。
当然,子信道划分的信息也可以是预定义的。
对于非竞争区域来说,由于终端的D2D链路(link)的传输是由网络侧设备或者CH调度的,因此也可以不需要子信道的划分信息,其采用FDM复用,TDM复用或者TDM+FDM复用,完全取决于网络侧设备或者CH的调度。
(五)、如上所述,D2D超帧由其时长内的D2D子帧构成。如果由网络侧设备分配D2D资源,那么,D2D终端接收到的D2D资源配置信息还包括:D2D子帧配置信息。生成的D2D资源配置信息还包括:D2D子帧配置信息。
D2D子帧配置信息可以但不仅限于包括D2D子帧的周期、占用的子帧编号或者子帧偏移量等等。
其中,生成的D2D资源配置信息中包括的D2D子帧配置信息的具体实现方式可以参照上述实施例的描述,不再赘述。
如果由作为簇头的D2D终端分配D2D资源,则每个子帧均为D2D子帧,因此,D2D 资源配置信息中不需要携带D2D子帧配置信息。
(六)、对于簇头分配D2D资源的情况,D2D超帧结构中可以包含R-REQ区域,用于CH覆盖下的D2D UE发送资源请求信息。资源请求信息中需要至少包括D2D link的缓存状态报告(BSR,Buffer Status Report),用于辅助CH分配资源。如果R-REQ区域与D2D超帧结构中的其他区域时分复用,相应的D2D超帧结构可以如图7所示,如果R-REQ区域与D2D超帧结构中的其他区域频分复用,相应的D2D超帧结构可以如图8所示。当然,也可以如图9所示,竞争区域与非竞争区域之间频分复用,R-REQ区域与竞争区域和非竞争区域时分复用。
对于R-REQ区域来说,一种比较好的方式是与竞争区域和非竞争区域以TDM的方式复用。
在R-REQ区域中的R-REQ信道之间可以采用FDM的复用方式。R-REQ信道的带宽可以是配置的也可以是预定义的,例如:固定R-REQ信道的带宽为M个PRB。当然,R-REQ区域中的R-REQ信道之间还可以采用TDM的复用方式,每个R-REQ占用的D2D子帧的数量可以是配置的,也可以是预定义的。R-REQ区域中的R-REQ信道之间还可以采用时分和频分混合复用方式。
另外,对于簇头分配D2D资源的情况,D2D超帧结构中也可以不包含R-REQ区域,但是这时候所有资源占用的请求都是通过在竞争区域中竞争的方式产生的,通常情况下R-REQ消息比较小,如果与数据都放在竞争区域中进行竞争传输,那么效率会比较低,因此不建议这种方式。
对于网络侧设备覆盖的情况,D2D UE可以沿用蜂窝链路(cellular link)的调度请求(SR)/BSR上报机制请求资源。因此可以不需要R-REQ信道。
那么,如果簇头分配D2D资源,则接收到的D2D资源配置信息还可以包括:D2D超帧中的R-REQ区域的资源位置信息;生成的D2D资源配置信息还可以包括:D2D超帧中的R-REQ区域的资源位置信息。
其中,生成的D2D资源配置信息包括的D2D超帧中的R-REQ区域的资源位置信息的具体实现方式可以参照上述实施例的描述,不再赘述。
(七)、D2D超帧中竞争区域内的信道可以采用频分复用方式,也可以采用时分复用方式,还可以采用时分和频分混合复用方式。其具体描述可以参照上述第(四)种情况的描述,这里不再赘述。相应的,D2D终端接收到的D2D资源配置信息还可以包括:竞争区域的子信道划分信息;生成的D2D资源配置信息还可以包括:竞争区域的子信道划分信息。
基于上述任一D2D终端侧方法实施例,较佳地,如果由网络侧设备分配D2D资源,D2D终端接收D2D资源配置信息的具体实现方式可以是,该D2D终端接收网络侧设备发 送的系统广播消息,该系统广播消息中携带D2D资源配置信息。当然,D2D终端也可以接收网络侧设备发送的该D2D终端的专属信令,该专属信令中携带D2D资源配置信息。
如果由簇头分配D2D资源,D2D终端接收D2D资源配置信息的具体实现方式还可以是,该D2D终端接收作为簇头的D2D终端在信标信息所在子帧中发送的D2D资源配置信息。可选的,D2D资源配置信息可以在信标信息所在子帧中的控制信道传输。
基于上述任一D2D终端侧方法实施例,较佳地,D2D终端通过获得的传输资源发送生成的D2D资源配置信息之前,该D2D终端获取传输资源。对于蜂窝或簇头覆盖范围内的D2D终端可以从竞争区域获取传输资源,也可以从非竞争区域获取传输资源。对于蜂窝和簇头覆盖范围外的D2D终端,仅可以从竞争区域获取传输资源。如图10所示,以D2D超帧结构中各区域TDM划分为例,Contention part为竞争区域,Contention free part为非竞争区域。由于UE2在簇头(CH)的覆盖范围外,无法接收到CH的调度信息,因此,UE2在竞争区域传输。UE1则既可以在竞争区域传输,也可以在非竞争区域传输。
如果从竞争区域获取传输资源,D2D终端根据接收到的D2D资源配置信息,确定D2D超帧的竞争区域;在该竞争区域,按照竞争的方式获取传输资源。
其中,如果D2D终端在预定时间内接收到一个D2D资源配置信息,那么,D2D终端确定D2D超帧的竞争区域为该D2D资源配置信息包括的竞争区域;可选的,如果该D2D资源配置信息中包括的D2D超帧中非竞争区域的层数与初始层数的差值不小于2(或者该层数达到最大层数阈值),D2D终端还可以确定该D2D资源配置信息包括的D2D超帧中非竞争区域为其可用的竞争区域。
如果D2D终端在预定时间内接收到多个D2D资源配置信息,那么,D2D终端可以按照生成新的D2D资源配置信息的方式确定其可用的竞争区域;可选的,如果有非竞争区域的层数在接收到的各个D2D资源配置信息中指示的层数与初始层数的差值均不小于2(或者层数均达到最大层数阈值),D2D终端还可以确定该非竞争区域为其可用的竞争区域。也就是说,如果D2D资源配置区域中非竞争区域的层数为最大层数阈值或者与初始层数的差值不小于2,那么,可以认为指示了该区域为竞争区域。
如果从非竞争区域获取传输资源,该D2D终端向网络侧设备或者作为簇头的D2D终端请求资源调度,根据网络侧设备或者作为簇头的D2D终端发送的调度信息获取D2D超帧中的非竞争区域的传输资源。
如果是网络侧设备调度,那么其通过下行控制信道(例如物理下行控制信道(PDCCH)/增强物理下行控制信道(EPDCCH))调度D2D UE在D2D link上的传输资源。
如果是CH调度,那么其可以通过信标(beacon)信息所在子帧指示其在非竞争区域中占用的资源位置,以及相应的调制编码方式。也可以通过D2D超帧中专门的控制信道指示其在非竞争区域中占用的资源位置以及相应的调制编码方式。
对于蜂窝或簇头覆盖范围内的D2D终端,选择从竞争区域还是非竞争区域获取传输资源,取决于通信需求。例如,如果需要提高网络的鲁棒性,则可以采用竞争的方式从竞争区域获取传输资源。如果需要提高资源的利用率,则可以采用调度的方式从竞争区域获取传输资源。
本发明实施例提供的一种D2D资源配置信息在D2D资源分配设备侧的传输方法如图11所示,具体包括如下操作:
步骤1100、D2D资源分配设备确定D2D超帧中的竞争区域,该D2D超帧由其时长内的D2D子帧构成;
步骤1110、该D2D资源分配设备生成D2D资源配置信息,该D2D资源配置信息包括所述D2D超帧中竞争区域的资源位置信息。
步骤1120、该D2D资源分配设备将上述D2D资源配置信息发送给D2D终端。
本发明实施例提供的方法,D2D资源分配设备确定D2D超帧中的竞争区域,生成并发送的D2D资源配置信息中包括竞争区域的资源位置信息,使得D2D终端能够获知竞争区域所在的资源位置,从而可以通过竞争获取竞争区域的资源位置信息,而不会与通过调度获得的传输资源发生冲突。
D2D资源分配设备侧方法实施例中存在于D2D终端侧方法相同或相似的技术特征,其具体实现方式可以参照D2D终端侧方法实施例的描述,不再赘述。
基于上述D2D资源分配设备侧方法实施例,D2D资源配置信息还可以包括以下任一参数或组合。
(一)、D2D资源配置信息还可以包括:D2D超帧的时长。
相应的,生成D2D资源配置信息之前,D2D资源分配设备还确定D2D超帧的时长。
(二)、D2D资源配置信息还可以包括:D2D超帧中非竞争区域的资源位置信息。
相应的,生成D2D资源配置信息之前,D2D资源分配设备还确定D2D超帧中的非竞争区域。
较佳地,D2D资源分配设备获取相邻D2D资源分配设备确定的D2D超帧中的非竞争区域的资源位置信息;该D2D资源分配设备根据获取的非竞争区域的资源位置信息,确定D2D超帧中的非竞争区域,该D2D资源分配设备确定的所述D2D超帧中的非竞争区域与相邻D2D资源分配设备确定的非竞争区域在时域或频域上正交。
如果D2D资源分配设备是网络侧设备,其可以通过X2接口获取相邻网络侧设备确定的非竞争区域的资源位置信息。如果D2D资源分配设备是作为簇头的D2D终端,其可以通过D2D link获取其他簇头或网络侧设备确定的非竞争区域的资源位置信息。
以两个相邻的簇头CH1和CH2为例,可以通过UE1和UE2传递各自划分的竞争区域和非竞争区域,经过资源协商后,使得CH1和CH2的非竞争区域分别在时域或频域上正 交,如图12所示。其中,非竞争(contention free)1是CH1的非竞争区域,非竞争(contention free)2是CH2的非竞争区域,UE1在传输的时候尽量避免在contention free 2中传输,UE2在传输时,尽量避免在contention free 1中传输。Contention为竞争区域。
如果D2D资源配置信息中包括D2D超帧中非竞争区域的资源位置信息,那么,第(三)种情况、D2D资源配置信息还可以包括:非竞争区域的层数,该层数为初始层数。
如果D2D资源配置信息中包括D2D超帧中非竞争区域的资源位置信息,那么,第(四)种情况、D2D资源配置信息还可以包括:非竞争区域的子信道划分信息。
(五)、如果D2D分配设备为网络侧设备,D2D资源配置信息还可以包括:D2D子帧配置信息。
(六)、如果D2D资源分配设备为作为簇头的D2D终端,D2D资源配置信息还可以包括:D2D超帧中的R-REQ区域的资源位置信息。
(七)、D2D资源配置信息还可以包括:竞争区域的子信道划分信息。
基于上述任一D2D资源分配设备侧方法实施例,较佳地,如果该D2D资源分配设备为网络侧设备,该D2D资源分配设备将所述D2D资源配置信息发送给D2D终端的具体实现方式可以是:网络侧设备向该D2D终端发送系统广播消息,该系统广播消息中携带D2D资源配置信息。
基于上述任一D2D资源分配设备侧方法实施例,较佳地,如果该D2D资源分配设备为作为簇头的D2D终端,该D2D资源分配设备将D2D资源配置信息发送给D2D终端的具体实现方式可以是:作为簇头的D2D终端在信标信息所在的子帧中向其他D2D终端发送D2D资源配置信息。
基于上述任一D2D资源分配设备侧方法实施例,D2D资源分配设备还可以接收D2D终端发送的资源调度请求,向所述D2D终端发送调度信息,该调度信息用于指示为所述D2D终端分配的传输资源,该传输资源在所述D2D超帧中的非竞争区域。较佳地,如果该D2D资源分配设备为作为簇头的D2D终端,作为簇头的D2D终端接收其他D2D终端发送的资源调度请求,在D2D超帧的信标信息所在子帧中发送调度信息。较佳地,如果该D2D资源分配设备为网络侧设备,该网络侧设备接收D2D终端发送的资源调度请求,通过下行控制信道向该D2D终端发送调度信息。
以图13所示的应用场景为例,其中,UE1在eNB的覆盖范围内,UE2在eNB的覆盖范围外。
eNB通过系统广播D2D资源配置信息1,其中包括D2D超帧结构信息,在D2D超帧结构信息中包含D2D子帧的配置信息,以及D2D超帧中竞争区域和非竞争区域的资源位置信息,可选的包含竞争区域中的子信道的配置信息。
如果UE1需要进行D2D link的传输,其有两种传输的方式:
一种是可以直接通过竞争区域,根据竞争区域中定义的竞争机制,例如能量检测和CSMA/CA的方式占用资源传输。这种情况相当于潜在UE1可以不进入无线资源管理(RRC)连接状态就进行传输,也就是可以既支持RRC连接状态也可以支持RRC空闲(idle)状态。
另一种方式是通过非竞争区域传输,如果UE1处于RRC idle状态,那么UE1首先通过cellular link的随机过程进入RRC连接状态,然后通过SR/BSR向eNB发送资源调度请求和BSR。eNB根据UE1的资源调度请求对其进行调度,其调度信息通过cellular link的PDCCH/EPDCCH指示给UE1。如果UE1处于RRC连接状态,那么UE1不需要经过随机接入信道(RACH)过程,可以直接通过SR/BSR向eNB发送资源调度请求和BSR。eNB根据UE1的资源调度请求对其进行调度,其调度信息通过cellular link的PDCCH/EPDCCH指示给UE1。
UE1根据D2D资源配置信息1生成D2D资源配置信息2,D2D资源配置信息2中需要包含资源配置信息1中的超帧结构信息。并在其发送数据的时候携带D2D资源配置信息2。
UE2接收UE1发送的D2D资源配置信息2,从而可以获知当前的超帧结构信息,相应的如果UE2需要进行数据的发送,由于其无法与eNB取得联系,那么UE2根据UE1发送的D2D资源配置信息2中定义的超帧结构中的竞争区域和非竞争区域信息,在竞争区域中以竞争的方式发送数据。同样,在UE2发送数据的时候,其需要携带资源配置信息3,其中资源配置信息3中至少需要包含资源配置信息2中的D2D link的超帧结构信息。
以图14所示的应用场景为例。其中,UE1在簇头的覆盖范围内,UE2在簇头的覆盖范围外。
CH通过beacon所在子帧广播D2D资源配置信息1,其中包括D2D超帧结构信息,在D2D超帧结构信息中包含D2D超帧中的竞争区域和非竞争区域的资源位置信息,可选的包含竞争区域中的子信道的配置信息。可选的还包含D2D超帧中的REQ区域的资源位置信息。
如果UE1需要进行D2D link的传输,其有两种传输的方式:
一种是可以直接通过竞争区域,根据竞争区域中定义的竞争机制,例如能量检测和CSMA/CA的方式占用资源传输。
另一种方式是通过非竞争区域传输,UE1首先通过R-REQ区域向CH发送资源调度请求,其中包含D2D link的BSR上报,可选的可以包含UE1监听到的信道状态的报告。CH根据接收到的UE1的资源调度请求进行调度,并在beacon所在子帧中指示UE1传输在非竞争区域占用的资源,可选的可以包含调制编码方案等传输属性相关的参数。
UE1根据D2D资源配置信息1生成D2D资源配置信息2,D2D资源配置信息2中需 要包含D2D资源配置信息1中的超帧结构信息。并在其发送数据的时候携带D2D资源配置信息2。
UE2接收UE1发送的D2D资源配置信息2,从而可以获知当前的超帧结构信息,相应的如果UE2需要进行数据的发送,由于其无法与CH取得联系,那么UE2根据UE1发送的D2D资源配置信息2中定义的超帧结构中的竞争区域和非竞争区域信息,在竞争区域中以竞争的方式发送数据。同样,在UE2发送数据的时候,其需要携带D2D资源配置信息3,其中D2D资源配置信息3中至少需要包含D2D资源配置信息2中的D2D超帧结构信息。
以图15所示的应用场景为例,其中,UE1在簇头的覆盖范围内,UE2和UE3在簇头的覆盖范围外。
eNB或者CH发送的D2D资源配置信息1中的非竞争区域的层数为1(当然,初始层数还可以是其他取值),相应的UE1位于网络覆盖内,其发送的D2D资源配置信息2中非竞争区域的层数为2,UE2位于网络覆盖外,其发送的D2D资源配置信息3中非竞争区域的层数为3。假设最大层数阈值为3。
对于UE3来说,其可以同时接收到UE1和UE2发送的D2D资源配置信息,其包含不同的非竞争区域的层数,那么UE3按照接收到的最小的层数(UE1的层数信息)及最大层数阈值确定其生成的D2D资源配置信息中非竞争区域的层数信息,其为:min(最小的层数+1,最大层数阈值)。
以图16所示的应用场景为例,其中,UE1在簇头的覆盖范围内,UE2和UE3在簇头的覆盖范围外。
假定2跳范围外,用户之间的同频干扰都比较小了,相应的可以认为在2跳之后的非竞争区域的资源可以被重用,那么根据非竞争区域的层信息,在UE3的位置,CH定义的非竞争区域的资源,可以在UE3重用。相当于UE3接收到UE2发送的D2D资源配置信息3中的非竞争区域的层信息是3,比CH发送的非竞争区域的层信息(层信息为1),其之间的差值不小于2。从而UE3可以认为这部分区域可以被重用。
由于2跳范围外,用户之间的同频干扰较小,那么,还可以将最大层数阈值确定为初始层数+2。
