Description

一种交互链路信息的方法、装置及系统
本申请要求在2013年4月3日提交中国专利局、申请号为 201310116364.1、发明名称为“一种交互链路信息的方法、装置及系统”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,特别涉及一种交互链路信息的方法、装置及 系统。
背景技术
在长期演进(Long Term Evolution,LTE)系统中,目前采取的通信方式 为网络集中控制的方式,即用户设备(User Equipment,UE;也称为终端)的 上/下行数据都需要在网络的控制下进行发送和接收。目前,UE与UE之间的 通信,是由网络进行转发和控制的,UE与UE之间不存在直接的通信链路, 这种方式下,UE和网络之间的数据传输可以简称为设备到网络(Device to  Network,D2N)传输,参见图1所示。
移动通信系统未来发展中,为了更好的满足用户需求,提升设备之间信 息交互的效率,引入了移动设备之间的互相发现(Device to Device Discovery, D2D Discovery),甚至直接通信(D2D Communication)的机制。在D2D通信 模式中,终端和终端之间允许进行一定的设备到设备的通信(Device to Device  Communication,D2D Communication),这些直接通信链路可以是在网络控制 或者辅助下建立起来的,参见图2所示。终端和终端之间进行D2D通信的基 础是对靠近的终端进行发现。
当前LTE系统中,终端只支持D2N传输,因此终端只会向网络侧上报与 D2N链路相关的信息,以使网络侧根据终端上报的D2N链路信息,做出正确 的决策。随着D2D的引入,支持D2D传输的终端,同时也应该支持D2N传 输,甚至同一个终端在同一时刻可能同时进行D2D传输和D2N传输。由于 D2D传输也是需要受网络控制的,因此就需要考虑如何让网络侧获知D2D链 路信息,并且能够将D2D链路信息和D2N链路信息进行区分,以便网络侧能 够对D2D链路及D2N链路进行管理和调度。但是,目前还没有给出网络侧如 何获知支持D2D通信的终端的链路信息的解决方案,也没有给出如何区分 D2D链路信息与D2N链路信息的解决方案。
综上所述,对于网络侧如何获知支持D2D通信的终端的链路信息,以及 如何区分D2D链路信息与D2N链路信息,目前还没有解决方案。

信道配置信息、天线模式配置信息、MAC层的参数配置信息、以及物理 层的参数配置信息。
在实施中,网络侧(如基站)通过显式信令配置终端进行D2D传输和/ 或D2N传输;相应的,终端基于网络侧的显式指示,确定进行D2D传输和/ 或D2N传输。
需要说明的是,网络侧在配置终端进行D2D传输之前,需要先获知该终 端支持D2D通信。优选的,终端向网络侧上报UE能力指示信息,并在该UE 能力指示信息中向网络侧指示该终端自身支持D2D通信。相应的,网络侧在 接收到该终端上报的UE能力指示信息后,根据该UE能力指示信息确定该终 端支持D2D通信,从而网络侧可以配置该终端进行D2D传输,网络侧也可以 为该终端的D2D传输配置资源等。
本发明实施例中,终端可能仅进行D2D传输,也可能仅进行D2N传输, 还可能同时进行D2D传输和D2N传输。
在实施中,终端基于网络侧显式指示,确定是否需要与网络侧交互D2D 链路信息和/或D2N链路信息。
例如,网络侧如果仅配置了UE进行D2N传输,那么终端仅需要和网络 侧交互D2N链路信息;如果网络侧同时配置了UE进行D2D和D2N传输, 那么终端需要同时和网络侧交互D2D链路信息和D2N链路信息;如果网络侧 仅配置终端进行D2D传输,那么终端仅需要和网络侧交互D2D链路信息。
在实施中,步骤31中,若终端需要向网络侧上报D2D链路信息与D2N 链路信息,则终端确定需要向网络侧上报的链路信息,包括以下方法:
方法1、终端分别对于D2D链路与D2N链路,确定需要上报的D2D链 路信息与D2N链路信息。
该方法下,相应的,步骤32中,终端在D2N链路上分别向网络侧上报 D2D链路信息及D2N链路信息。
例如,对于D2D链路与D2N链路,终端分别进行缓冲区状态报告(Buffer  State Report,BSR)/功率余量报告(Power Headroom Report,PHR)触发条 件的判断,并在满足BSR/PHR触发条件时,分别向网络侧上报D2D链路的 BSR/PHR,及D2N链路的BSR/PHR。
又如,终端根据自身对D2D链路的测量结果,确定D2D链路的CSI;终 端根据自身对D2N链路的测量结果,确定D2N链路的CSI;以及终端在不同 资源上向网络侧上报D2D链路的CSI及D2N链路的CSI。
方法2、终端分别对于D2D链路与D2N链路,确定需要上报的D2D链 路信息与D2N链路信息,并将确定的D2D链路信息与D2N链路信息一次上 报给网络侧。
具体的,终端可以将D2D链路信息与D2N链路信息打包上报。
该方法下,相应的,步骤32中,终端在D2N链路上向网络侧上报链路 信息,该链路信息包括D2D链路信息及D2N链路信息。
例如,对于D2D链路与D2N链路,终端分别进行BSR/PHR触发条件的 判断,并在满足BSR/PHR触发条件时,将D2D链路的BSR/PHR及D2N链 路的BSR/PHR打包在一个媒体接入控制层控制单元(MAC Control Element, MAC CE)中,并将该MAC CE上报给网络侧。
在实施中,步骤32中,终端通过以下任一方式指示网络侧该链路信息对 应的链路:
方式A、终端通过链路信息中携带的指示信息,向网络侧指示该链路信 息对应的链路。
具体的,若终端向网络侧上报D2D链路信息,则该终端在该D2D链路信 息中携带用于向网络侧指示该链路信息对应的链路为D2D链路的指示信息; 若终端向网络侧上报D2N链路信息,则该终端在该D2N链路信息中携带用于 向网络侧指示该链路信息对应的链路为D2N链路的指示信息。
作为另一种实现方式,若终端向网络侧上报的链路信息仅包括D2D链路 信息(或D2N链路信息),则:终端可以通过该链路信息中是否携带指示信 息,指示该链路信息对应的链路。
具体的,若该链路信息中没有携带任何用于指示链路的指示信息,则默 认该链路信息对应的链路是D2N链路;若该链路信息中携带了用于指示链路 的指示信息,则默认该链路信息对应的链路是D2D链路。
进一步,若终端将D2D链路信息与D2N链路信息打包后上报给网络侧, 则该终端在该链路信息中携带用于指示该链路信息中哪部分是D2D链路信息 及哪部分是D2N链路信息的指示信息。
比如,如果D2D链路信息和D2N链路信息长度都是固定的,那么打包时, 可以按照固定顺序打包,根据信息出现的位置区分D2D链路信息和D2N链路 信息;如果D2D链路信息和D2N链路信息长度是不固定的,那么可以显式指 示每个链路信息(即D2D链路信息和D2N链路信息)的长度。
方式A中,终端可以使用链路信息中预留的比特信息表示上述指示信息, 例如,使用1bit信息指示该链路信息针对的是D2D链路还是D2N链路(如 “0”表示D2D链路,“1”表示D2N链路);终端也可以使用链路信息中新增 的信息域表示上述指示信息。
进一步,若终端具有至少两条D2D链路,且该指示信息指示的链路为 D2D链路,则该指示信息中还携带该D2D链路的编号,以向网络侧指示该链 路信息针对的是哪条D2D链路。
在实施中,D2D链路的编号可以在D2D连接建立时配置。
方式B、终端通过承载链路信息的资源,指示网络侧该链路信息对应的 链路。
具体的,终端通过网络侧为自身的D2D链路分配的第一资源发送D2D链 路信息以及通过网络侧为的自身的D2N链路分配的第二资源发送D2N链路信 息。
举例说明,假设网络侧为终端配置资源A用于传输D2D链路信息,以及 为该终端配置资源B用于传输D2N链路信息,则:
若终端确定需要传输D2D链路信息,则通过资源A将确定的D2D链路 发送给网络侧;相应的,若网络侧在资源A接收到终端的链路信息,则确定 该链路信息对应的是D2D链路;
若终端确定需要传输D2N链路信息,则通过资源B将确定的D2N链路 发送给网络侧;相应的,若网络侧在资源B接收到终端的链路信息,则确定 该链路信息对应的是D2N链路。
进一步,若终端具有至少两条D2D链路,对于每条D2D链路,网络侧为 终端配置的第二资源还携带有该D2D链路的编号,以表示该第二资源针对的 是哪条D2D链路。
在实施中,D2D链路的编号可以在D2D连接建立时配置。
本发明实施例中,第一资源包括以下资源中的一种或组合:时域资源、 频域资源、空域资源、以及码域资源。
本发明实施例中,第二资源包括以下资源中的一种或组合:时域资源、 频域资源、空域资源、以及码域资源。
在实施中,对于D2D链路和/或D2N链路的BS信息:
终端在确定满足D2D链路和/或D2N链路的BSR触发条件且该D2N链 路具有上行资源时,将D2D链路和/或D2N链路的BSR以MAC CE形式上报 给网络侧,并通过MAC CE形式的BSR(记为BSR MAC CE)向基站指示该 BSR对应的链路。
在实施中,D2D链路的BSR触发条件包括:
D2D链路常规BSR(Regular BSR)触发条件、D2D链路周期性BSR (Periodic BSR)触发条件、以及D2D链路捎带BSR(Padding BSR)触发条 件。
其中,D2D链路常规BSR触发条件包括:在D2D链路对应的缓冲区由 空变为非空或者有更高优先级的数据到达时,触发该D2D链路的BSR上报; 或者,在D2D链路对应的重传BSR定时器retxBSR-Timer超时且该D2D链 路对应的缓冲区中有数据时,触发该D2D链路的BSR上报。
D2D链路周期性BSR触发条件包括:在D2D链路的BSR周期上报定时 器periodicBSR-Timer超时,触发该D2D链路的周期性BSR上报。
D2D链路捎带BSR触发条件包括:终端在组织D2D链路的媒体接入控 制分组数据单元(MAC Packet Data Unit,MAC PDU)时,若除了需要传输的 数据外还有可用资源,触发该D2D链路的捎带BSR上报。
在实施中,D2N链路的BSR触发条件包括:D2N链路常规BSR触发条 件、D2N链路周期性BSR触发条件、以及D2N链路捎带BSR触发条件。
其中,D2N链路常规BSR触发条件包括:在D2N链路对应的缓冲区由 空变为非空或者有更高优先级的数据到达时,触发该D2N链路的BSR上报; 或者,在D2N链路对应的重传BSR定时器retxBSR-Timer超时且该D2N链 路对应的缓冲区中有数据时,触发该D2N链路的BSR上报。
D2N链路周期性BSR触发条件包括:在D2N链路的BSR周期上报定时 器periodicBSR-Timer超时,触发该D2N链路的周期性BSR上报。
D2N链路捎带BSR触发条件包括:终端在组织D2N链路的媒体接入控 制分组数据单元(MAC Packet Data Unit,MAC PDU)时,若除了需要传输的 数据外还有可用资源,触发该D2N链路的捎带BSR上报。
进一步,终端在确定满足D2D链路和D2N链路的BSR触发条件且D2N 链路具有上行资源时,通过以下任一方式发送D2D链路和D2N链路的BS信 息:
终端将D2D链路和D2N链路对应的BSR通过一个MAC CE上报给基站, 并通过MAC CE形式的BSR向基站指示该BSR对应的链路(即打包上报); 或者
终端分别将D2D链路和D2N链路对应的BSR通过一个MAC CE上报给 基站,并通过每个MAC CE形式的BSR向基站指示该BSR对应的链路(即 分别上报)。
进一步,终端通过MAC CE形式的BSR向基站指示该BSR对应的链路, 包括以下两种方式:
方式一、终端通过MAC CE形式的BSR对应的MAC子头中或者MAC CE 中的预留比特位,指示该BSR对应的链路
具体的,以MAC CE的MAC子头为例进行说明,MAC CE的MAC子 头(sub-header)的格式如图4所示,其各个域的含义如下:R:预留比特;E: 扩展比特,用于指示下一个byte是MAC子头还是负荷部分;LCID(Logical  Channel ID,逻辑信道标识):用于标识对应负荷部分的逻辑信道号。在MAC  CE形式的BSR中可以取一个R bit,用该R bit标识该BSR针对的链路,例 如,该R取“1”表示该BSR MAC CE针对是D2D链路,取“0”表示该BSR  MAC CE针对的是D2N链路。
方式二、终端通过MAC CE形式的BSR对应的MAC子头中的LCID域, 指示该BSR对应的链路
具体的,对D2D链路的BSR MAC CE引入新的LCID,通过BSR MAC CE 对应的MAC子头的LCID域的取值区分该BSR MAC CE针对的是D2D链路 还是D2N链路。
进一步,若终端具有至少两条D2D链路,且该指示信息指示的链路为 D2D链路,则指示信息还需要指示该链路信息针对的是哪条D2D链路。
举例说明,假设终端具有1条D2N和2条D2D链路,则对于上述方式一, 终端可以使用MAC CE子头中的2个R bit指示链路信息对应的链路,如取 “00”表示针对D2N链路,取“01”表示针对第一条D2D链路,取“11”表 示针对第二条D2D链路。其中,D2D链路的编号可以子D2D连接建立时分 配。
在实施中,终端仅根据自身缓存区中需要在D2D链路上传输的数据和控 制信息的数据量,确定D2D链路的BS信息并组织该D2D链路的BSR MAC  CE;和/或,终端仅根据自身缓存区中需要在D2N链路上传输的数据和控制 信息的数据量,确定D2D链路的BS信息并组织该D2N链路的BSR MAC CE。
进一步,若终端需要上报D2D链路的CSI,则:终端根据D2D链路的测 量结果,确定该D2D链路的CSI。优选的,终端在确定的该D2D链路的CSI 中携带指示信息,用于指示该CSI是针对D2D链路的。
基于上述实施例,本发明实施例还提供了一种链路信息的接收方法,参 见图5所示,包括以下步骤:
步骤51、网络侧接收支持D2D通信的终端上报的链路信息,并确定该链 路信息对应的链路,该链路信息包括D2D链路信息和/或D2N链路信息;
步骤52、网络侧根据接收到的链路信息,对该链路信息对应的链路进行 管理及调度。

信道配置信息、天线模式配置信息、MAC层的参数配置信息、以及物理 层的参数配置信息。
在实施中,网络侧(如基站)通过显式信令配置终端进行D2D传输和/ 或D2N传输;
相应的,终端基于网络侧的显式指示,确定进行D2D传输和/或D2N传 输。
需要说明的是,网络侧在配置终端进行D2D传输之前,需要先获知该终 端支持D2D通信;
优选的,终端向网络侧上报UE能力指示信息,并在该UE能力指示信息 中向网络侧指示该终端自身支持D2D通信。
相应的,网络侧在接收到该终端上报的UE能力指示信息后,根据该UE 能力指示信息确定该终端支持D2D通信,从而网络侧可以配置该终端进行 D2D传输,网络侧也可以为该终端的D2D传输配置资源等。
本发明实施例中,终端可能仅进行D2D传输,也可能仅进行D2N传输, 还可能同时进行D2D传输和D2N传输。
在实施中,步骤51中,网络侧根据以下任一方式确定接收到的链路信息 对应的链路:
网络侧根据该链路信息中携带的指示信息,确定该链路信息对应的链路;
网络侧根据承载该链路信息的资源,确定该链路信息对应的链路,其中, 网络侧为终端的D2D链路分配的第一资源以及网络侧为终端的D2N链路分配 第二资源;
具体的,若网络侧在第一资源接收到链路信息,则确定该链路信息针对 的是D2D链路;若网络侧在第二资源接收到链路信息,则确定该链路信息针 对的是D2N链路。
进一步,若终端具有至少两条D2D链路,且指示信息指示的链路为D2D 链路,则该指示信息中还携带该D2D链路的编号;或者,若终端具有至少两 条D2D链路,对于每条D2D链路,网络侧为该终端配置的第二资源还携带有 该D2D链路的编号。
由于上述网络侧确定链路信息对应的链路的方式与上述终端侧的方式A 及方式B相同,具体参见方式A及方式B的描述,此处不再赘述。
本发明实施例中,第一资源包括以下资源中的一种或组合:时域资源、 频域资源、空域资源、以及码域资源。

进一步,网络侧根据MAC CE形式的BSR确定该BSR对应的链路,包 括以下两种方式:
网络侧根据该MAC CE形式的BSR对应的MAC子头或MAC CE中的预 留比特位,确定该BSR对应的链路;或者,
网络侧根据该MAC CE形式的BSR对应的MAC子头中的LCID域,确 定该BSR对应的链路。
由于上述网络侧根据MAC CE形式的BSR确定该BSR对应的链路的方 式与上述终端侧的方式一及方式二相同,具体参见方式一及方式二的描述, 此处不再赘述。
需要说明的是,终端具体采用哪种方式指示链路信息对应的链路以及网 络侧具体采用哪种方式确定链路信息对应的链路,可以由网络侧确定后通过 高层信令配置给终端,也可以由终端与网络侧协商或约定具体方式,还可以 在协议中规定。
下面给出两个具体实施例,对本发明实施例的终端与网络侧交互信息的 过程进行说明。
实施一、以BSR为例,说明UE和网络侧交互信息中显式携带链路指示 信息。
假设基站通过显式信令配置UE进行D2D传输,同时UE还有D2N传输, 则:
首先,UE分别针对D2D链路和D2N链路,按照各自链路的BSR触发条 件,判断相应链路是否有BSR触发;当D2D链路和/或D2N链路有BSR触 发且D2N链路有上行资源时,UE进行BSR上报;其中,BSR上报信息中显 式携带链路指示信息。
具体的,该链路指示信息可以携带在BSR MAC CE或者BSR MAC CE 对应的MAC子头中。
以链路指示信息显式携带在BSR MAC CE对应的MAC子头为例,具体 可以有两种方法:
第一种方法:在BSR MAC CE子头中取一个R bit,用该R bit取值标识 该BSR MAC CE针对的链路,比如取1标识该BSR MAC CE针对是D2D链 路,取0标识该BSR MAC CE针对的是D2N链路。
第二种方法:对D2D链路的BSR MAC CE引入新的LCID,利用BSR MAC  CE对应的MAC子头的LCID域取值区分该BSR MAC CE针对的是D2D链 路还是针对D2N链路。
需要说明的是,本实施例是以一条D2D和一条D2N链路为例进行说明的, 如果有多条D2D和D2N链路,那么显式指示信息中还需要区分该链路信息是 针对哪条D2D链路的,比如有1条D2N和2条D2D,那么对于第一种方法 可以利用2个R bit指示,如两个R bit均取0,则表示针对D2N链路;如果 取01,则表示针对第一条D2D链路;如果取11,则表示针对第二条D2D链 路。其中,D2D链路的编号可以在D2D连接建立时分配。
实施例二、以SR为例,说明通过频域资源划分的方式区分D2D链路和 D2N链路对应的链路信息,通过其它资源划分的方式区分不同链路的链路信 息的方法与之类似,此处不再赘述。
现有版本8(Release8,R8)中,SR传输使用的资源配置信息单元 (Information Element,IE)描述如下:
Figure PCTCN2014074622-appb-000001
Figure PCTCN2014074622-appb-000002
其中:
sr-PUCCH-ResourceIndex表示用于UE传输SR的PUCCH资源;
sr-ConfigIndex表示SR资源的周期和子帧偏移量。
假设基站通过显式信令配置UE进行D2D传输,同时UE还有D2N传输, 那么基站在为UE配置SR资源时,可以分别针对D2D链路和D2N链路配置 不同的资源,比如SR资源配置方式可以如下:
Figure PCTCN2014074622-appb-000003
上述配置标识D2N链路可以使用的SR资源;
Figure PCTCN2014074622-appb-000004
Figure PCTCN2014074622-appb-000005
上述配置标识D2D链路可以使用的SR资源。
相应的,UE在接收到上述配置信息后,若D2N链路有SR触发,则UE 使用D2N链路对应的SR资源发送D2N链路的调度请求;若D2D链路有SR 触发,则UE使用D2D链路对应的SR资源发送D2D链路的调度请求。这样 就可以保证基站能够根据接收到的SR传输时使用的资源区分是应该为D2N 链路还是D2D链路分配PUSCH资源。
需要说明的是,本实施例中是以一条D2D和一条D2N链路为例进行说明 的,如果有多条D2D和D2N链路,那么资源配置时还需要携带D2D链路的 编号,以表示该资源针对的是哪条D2D链路,其中D2D链路的编号可以在 D2D连接建立时分配。
上述方法处理流程可以用软件程序实现,该软件程序可以存储在存储介 质中,当存储的软件程序被调用时,执行上述方法步骤。
