Abstract

提供了一种由网络节点执行的方法，包括：向用户设备发送ProSe资源测量指示信息，所述ProSe资源测量指示信息包括指示所述ProSe资源在时频域上的位置的信息以及所述ProSe资源上的参考信号的标识信息；以及向用户设备发送ProSe资源测量上报配置信息。还提供了一种相应的网络节点和用户设备。通过本发明，用户设备能够对Sidelink资源进行测量并将测量结果上报给基站。

Description

用户设备、网络节点和测量方法 技术领域
本发明涉及无线通信技术领域。更具体地，本发明涉及针对用户设备间通信(D2D)的测量方法以及相应的网络节点和用户设备。
背景技术
现代无线移动通信系统呈现出两个显著特点，一是宽带高速率，比如第四代无线移动通信系统的带宽可达100MHz，下行速率高达1Gbps；二是移动互联，推动了移动上网、手机视频点播、在线导航等新兴业务。这两个特点对无线移动通信技术提出了较高要求，主要有：超高速率无线传输、区域间干扰抑制、移动中可靠传输信号、分布式/集中式信号处理等等。在未来的增强第四代(4G)及第五代(5G)无线移动通信系统中，为了满足上述发展需求，各种相应的关键技术开始被提出和论证。
为了实现上述发展需求，国际第三代伙伴计划(3GPP)组织在第58次全会上讨论并通过了将设备到设备(D2D)通信技术作为增强的第四代无线移动通信系统的关键技术。D2D技术可以实现本地通信或对等的点对点通信，而无需接入核心网络，采用D2D技术的传输方式，在减轻基站负载和延长移动终端电池的使用时间上都有十分积极的作用。通常根据实现D2D传输的用户设备(以下称为D2D用户设备)所处的场景是否有宏基站的覆盖，可以将D2D用户设备的场景划分为：有网络覆盖下、无网络覆盖下以及部分网络覆盖，其中部分网络覆盖的场景是指，包含有网络覆盖和无网络覆盖的D2D用户设备的情况。
在部分网络覆盖的场景中，部分D2D用户设备可以作为中继转发“适地服务”(ProSe，Proximity-based Services)业务，增加网络覆盖范围。因此当D2D用户设备处于基站的覆盖范围内时，基站为其提供ProSe业务，当D2D用户设备处于中继的覆盖范围内时，中继为其提供ProSe业务。考虑到D2D用户设备的移动性，需要重选接入基站或者中继。为了保证业务的延续性，当D2D用户设备重选接入到基站或中继时，需要服从基站的控 制。因此，用户设备需要做无线资源的测量，并将测量结果上报给基站，以便基站做出正确的判断。

下文以LTE移动通信系统及其后续的演进版本作为示例应用环境，具体描述了根据本发明的多个实施例。然而，需要指出的是，本发明不限于以下实施例，而是可适用于更多其它的无线通信系统，例如今后的5G蜂窝通信系统。在下文中，除非另有明示，所提及的通信系统、网络节点和用户设备均指代支持D2D的通信系统、网络节点和用户设备。
在本发明中，D2D用户设备测量网络节点的解调参考信号，当满足一定的条件后将测量结果上报给网络节点(例如基站)。如图1所示，首先网络节点10向用户设备UE 20配置ProSe资源测量指示信息(S201)。UE 20接收ProSe资源测量指示信息(S202)，并在相应的时频资源上测量参考信号的RSRP值或者RSRQ值(S203)。此外，当满足事件触发准则时，还可以触发UE 20上报测量数值(图1中未示出，详情见下文描述)。
类似于蜂窝用户设备的无线资源测量配置，在本申请中，用户设备的ProSe无线资源测量配置包括测量对象、上报配置、测量标识、数量配置、以及测量间隙，等等。其中，测量对象(ProSe无线资源)是LTE网络配置给ProSe业务的上行资源池。该资源池在时频域上的位置由信元sl-CommResourcePool指示给用户设备。该资源池的特性，例如标识(measSidelink-Id)、同步信号标识(SLSSID)、所属小区物理标识(physCellId)、以及该资源池上用于测量的参考信号的加扰(scramblingIdentity)等均由信令MeasSidelink-Config配置给用户设备。信令信元MeasSidelink-Config结构如下。

在S330处，网络节点向用户设备发送ProSe资源测量上报配置信息。在一个实施例中，ProSe资源测量上报配置信息包括触发用户设备发送测量报告的事件驱动准则以及用户设备报告的内容。
例如，用户设备可以根据信元ReportConfigSidelink中的配置信息，当满足条件就触发测量上报。其中，配置信息ReportConfigSidelink包括触发上报事件S1-S7驱动准则及相应的参数，例如门限，偏置等。具体结构如下：
