Description

信息传输装置、方法以及通信*** 技术领域
本发明涉及无线通信技术领域，特别涉及一种信息传输装置、方法以及通信***。
背景技术
边链路(Sidelink)通信方式是指数据包无需通过核心网和基站，用户设备UE1和UE2之间可以直接建立通信链路而进行通信。边链路通信也可以称为设备到设备(D2D，Device to Device)通信。在进行边链路(Sidelink)通信前，一般会进行边链路发现过程。例如，UE1要通过边链路通信方式发送信息给UE2之前，先要发现UE2是否在附近。
图1是边链路通信的一个示意图，示出了两个都在基站(例如eNB)覆盖下的UE(UE1和UE2)进行边链路发现或建立边链路通信的情况。图2是边链路通信的另一个示意图，示出了一个UE(UE1)在基站覆盖下而另一个UE(UE2)不在基站覆盖下时，进行边链路发现或建立边链路通信的情况。图3是边链路通信的另一个示意图，示出了两个都不在基站覆盖下的UE(UE1和UE2)进行边链路发现或建立边链路通信的情况。
边链路通信方式可以用于扩大小区覆盖范围。下面结合图1和图2给出两个扩大覆盖范围的例子。
场景1：如图1所示，一个用户设备(UE2)位于小区边缘而信号比较弱，很可能即将离开该小区的覆盖。另外，附近有被网络授权的具有中继功能的用户设备(例如UE1)。为了避免业务中断，UE2发现该中继(也可称为中继用户设备)UE1后，可以通过该中继UE1接入基站，继续进行正常的业务通信。
场景2：如图2所示，一个用户设备(例如UE2)位于没有网络覆盖的区域。并且，附近有被网络授权的具有中继功能的用户设备(例如UE1)。为了接入网络进行通信，UE2发现位于小区覆盖内的中继UE1后，可以通过该中继UE1接入基站。
在上述场景描述中，UE2可以被称为远程用户设备(remote UE)，该远程用户设备可能位于小区覆盖之内，也可能位于小区覆盖之外。具有中继功能的用户设备(例如UE1)可以被称为中继用户设备，也被称为终端-网络间中继(UE-Network relay)， 也可以简称为中继。
应该注意，上面对技术背景的介绍只是为了方便对本发明的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本发明的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
本发明实施例提供一种信息传输装置、方法以及通信***。非第三代伙伴项目(3GPP，3rd Generation Partnership Project)通信技术(例如蓝牙技术或者WIFI技术)被用在远程用户设备和中继用户设备之间进行通信。
根据本发明实施例的第一个方面，提供一种信息传输方法，包括：

根据本发明实施例的第三个方面，提供一种信息传输方法，包括：
基站接收远程用户设备上报的包括中继用户设备的标识的信息，所述信息还指示所述远程用户设备支持与所述中继用户设备进行边链路通信和/或非3GPP通信；以及
基站配置所述远程用户设备和/或所述中继用户设备使用边链路、非3GPP链路以及空口链路中的一种或多种进行通信。
根据本发明实施例的第四个方面，提供一种信息传输装置，配置于基站，所述信息传输装置包括：

具体实施方式
参照附图，通过下面的说明书，本发明的前述以及其它特征将变得明显。在说明书和附图中，具体公开了本发明的特定实施方式，其表明了其中可以采用本发明的原 则的部分实施方式，应了解的是，本发明不限于所描述的实施方式，相反，本发明包括落入所附权利要求的范围内的全部修改、变型以及等同物。
在本申请中，基站可以被称为接入点、广播发射机、节点B、演进节点B(eNB)等，并且可以包括它们的一些或所有功能。在文中将使用术语“基站”。每个基站对特定的地理区域提供通信覆盖。术语“小区”可以指的是基站和/或其覆盖区域，这取决于使用该术语的上下文。
在本申请中，移动站或设备可以被称为“用户设备”(UE，User Equipment)。UE可以是固定的或移动的，并且也可以称为移动台、终端、接入终端、用户单元、站等。UE可以是蜂窝电话、个人数字助理(PDA)、无线调制解调器、无线通信设备、手持设备、膝上型计算机、无绳电话、可穿戴设备等。
图4是远程用户设备选择/重选中继用户设备的示意图，如图4所示，位于小区覆盖内的远程用户设备发现并选择一个中继用户设备后，远程用户设备会发送信息告诉基站其选择了该中继用户设备。基站收到该信息后，会给该远程用户设备分配边链路资源。
远程用户设备在分配的资源上可以发送连接建立请求给选中的中继用户设备。中继用户设备收到该信息后，将向基站发送资源请求信令。基站收到该中继发送的请求信息后，可能基于资源不足的考虑，拒绝分配资源给该中继用户设备。在这种基站不知道该远程用户设备和中继用户设备是配对用户的情况下，导致出现基站分配资源给远程用户设备，但不分配资源给中继用户设备的情形。
实施例1
本发明实施例提供一种信息传输方法。
图5是本发明实施例的信息传输方法的一个示意图，示出了远程用户设备一侧的情况。如图5所示，该信息传输方法包括：
步骤501，远程用户设备向基站上报包括中继用户设备的标识的信息，该信息还指示远程用户设备支持与中继用户设备进行边链路通信和/或非3GPP通信；
步骤502，远程用户设备基于基站配置的通信链路或者自主选择的通信链路进行通信。
在本实施例中，可以适用于如图1或4所示的场景，远程用户设备和中继用户设 备均处于小区覆盖范围内。其中，基站可以为宏基站(例如eNB)，该宏基站产生的宏小区(例如Macro cell)可以为用户设备提供服务；或者该基站也可以为微基站，该微基站产生的微小区(例如Pico cell或small cell)可以为用户设备提供服务。但本发明不限于此，还可以适用于其他的场景。
在本实施例中，非3GPP通信可以包括：蓝牙通信和/或无线保真(WIFI)通信；例如采用的是非授权频段。但本发明不限于此，例如还可以是其他的通信方式。其中，非3GPP通信的链路可以为一个或多个。此外，远程用户设备或中继用户设备也可以通过空口(例如Uu接口)与基站进行通信。
在本实施例中，远程用户设备还可以根据基站的配置信息，对边链路通信的链路(以下简称为边链路)和/或非3GPP通信的链路(以下简称为非3GPP链路)进行测量；并且上报边链路和/或非3GPP链路的测量结果。
例如，远程用户设备可以向基站上报目前其自身支持的边链路、蓝牙链路和WIFI链路中的一种或多种通信链路，并且包含可接入中继用户设备的ID，远程用户设备上报的可选链路在基站支持的范围内。或者，如果基站配置远程用户设备进行测量上报，该远程用户设备可以向基站上报有关蓝牙链路和/或WIFI链路的测量结果，并且该测量结果中包含相应的中继用户设备的ID。
图6是本发明实施例的信息传输方法的另一个示意图，示出了基站一侧的情况。如图6所示，该信息传输方法包括：

由此能够支持远程用户设备与中继用户设备进行边链路通信和/或非3GPP通信。
图7是本发明实施例的信息传输方法的另一个示意图，示出了远程用户设备和基站的情况。如图7所示，该信息传输方法包括：
步骤701，基站发送是否支持将边链路通信和/或非3GPP通信用于远程用户设备和中继用户设备之间的指示信息。
例如，基站可以通过无线资源控制(RRC，Radio Resource Control)信令来指示是否支持将边链路通信、蓝牙通信和WIFI通信中的一种或多种用于远程用户设备和 中继用户设备之间的通信。
步骤702，基站广播用于特例场景的资源；所述特例场景被配置为使用边链路通信和/或非3GPP通信。
例如，基站可以为特例场景(exceptional case)配置边链路通信、蓝牙通信和WIFI通信中的一种或多种。如果边链路(或者，蓝牙或WIFI)可用于特例场景，基站可以同时广播相关的资源池。当特例场景发生时，用户设备可以自主地从支持的资源中选择一种通信技术用于继续传输数据，即使该用户设备被配置为使用调度资源传输数据。
关于特例场景，例如基站发生无线链路失败(RLF，Radio Link Failure)的场景，或者发生切换的场景；关于特例场景的具体内容，可参考长期演进(LTE，Long Term Evolution)***的36.331 V13.1.0。
步骤703，远程用户设备向基站上报包括中继用户设备的标识的信息，该信息还指示远程用户设备支持与中继用户设备进行边链路通信和/或非3GPP通信；
步骤704，远程用户设备基于基站配置的通信链路或者自主选择的通信链路进行通信。
例如，远程用户设备可以基于基站配置的空口链路与基站进行通信，或者基于基站配置的WIFI链路与中继用户设备进行通信，或者基于自主选择的蓝牙链路与中继用户设备进行通信。
值得注意的是，图7仅示意性地对本发明实施例进行了说明，例如，中继用户设备如何与基站进行交互的内容在图7中被省略。但本发明不限于此，可以适当地调整各个步骤之间的执行顺序，此外还可以增加其他的一些步骤或者减少其中的某些步骤。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图的记载。
由上述实施例可知，远程用户设备向基站上报包括中继用户设备的标识的信息，该信息还指示远程用户设备支持与中继用户设备进行边链路通信和/或非3GPP通信；远程用户设备基于基站配置的通信链路或者自主选择的通信链路进行通信。
由此，不仅可以使得用户设备节能，例如远程用户设备可以只和邻近的中继用户设备进行数据传输而不必增大功率地与基站通信；而且可以保持数据传输的连续性，例如当空口链路出现问题时，远程用户设备可以选择非3GPP的通信技术和中继用户 设备进行通信，从而避免了传输过程被中断的问题。
