在3GPP(3rd Generation Partnership Project)组织的基于LTE(Long Term Evolution,长期演进)的V2X通信研究中,基于UE之间的直通/Sidelink的V2X通信方法是V2X标准实现的方式之一,即业务数据不经过基站和核心网的转发,直接由源用户设备通过空口传输给目标用户设备,如图1所示,这种V2X通信方式简称基于PC5(PC5-based)V2X通信或V2X sidelink通信。
随着技术进步与自动化产业发展,V2X通信场景进一步延伸且有更高的性能需求。高级V2X业务主要分为4大类:车辆组队(vehicle platooning),扩展传感器(extended sensors),高级驾驶(半自动驾驶、全自动驾驶(semi-automated or full-automated driving))以及远程驾驶(remote driving)。要求达到的性能需求:数据包大小支持50到12000字节,传输速率每秒2到50条消息,最大端到端延时3-500毫秒,可靠性90%-99.999%,数据率0.5-1000Mbps,以及传输范围支持50-1000米。此外,高级V2X业务还要求实时上报QoS状态,QoS更新实时上报,以及支持基于时间地点场景/环境的QoS预测、QoS协商,从而协助调整不同V2X环境下的自动驾驶等级或者驾驶行为,以及进行网络调度优化更好地保证服务质量。但是相关技术中尚未有车联网业务相关或直通链路上通信服务质量的检测机制。

实施例三:
图3为本发明实施例提供的另一种sidelink路测配置及上报流程示意图,该方法主要应用与配置侧为基站(网络侧),终端为车联网UE的情况下。
基站下发sidelink路测配置信息,UE执行sidelink通信路测,获取sidelink路测信息并上报给基站。
由于覆盖内UE由基站为UE配置sidelink通信资源/资源池,所以PC5接口的资源使用/拥塞/负荷/QoS情况让网络知道,有助于网络更好地进行sidelink资源配置与调度或用于预测sidelink QoS。
Sidelink通信路测,可考虑以下测量项(目):
M1:sidelink资源池拥塞测量。在R14 V2X中,引入了sidelink拥塞控制机制,会对资源池进行信道忙闲率CBR测量,根据CBR测量及时调整发送参数。在CBR的基础上对资源池拥塞情况进行统计,可辅助网络调整资源池配置或发送参数配置。具体如,基站下发测量配置信息,包括以下至少之一:要测量的资源池,配置信道忙闲率CBR阈值,测量周期,上报周期,触发上报阈值(次数或比例)。UE基于测量配置信息执行CBR测量,统计在测量周期内CBR测量值大于CBR阈值的次数,或者测量周期内CBR测量值大于CBR阈值的次数与总的CBR测量次数的比值。UE记录测量结果,当达到上报周期时上报测量结果,或者,当CBR测量值大于CBR阈值的次数或比例达到触发上报阈值时则触发上报测量结果。
M2:sidelink资源池资源冲突统计。UE在选择资源时会进行侦测(sensing),如果发现该资源已被选择/预留/使用,则不选择该资源。通过对sidelink资源池资源冲突情况统计,可以辅助网络优化资源池配置或资源选择配置参数。具体地,基站下发测量配置信息,包括以下至少之一:要测量的资源池,测量周期,上报周期,触发上报阈值(次数或比例)。UE基于测量配置执行测量,统计在测量周期内资源池上发生资源冲突的次数,或者在测量周期内资源池上发生资源冲突的次数与资源池上总的资源选择次数的比值。或者统计在sensing及资源选择时,选出足够(满足资源选择20%比例)可用资源的概率。UE记录测量结果,当达到上报周期时上报测量结果,或者,当上述次数或比值达到触发上报阈值时则触发上报测量结果。
M3:覆盖测量。指记录使用基站配置资源、预配置资源、运营商管理资源或非运营商管理资源、检测到的限制服务状态或使用的资源类型发生变化时的时间及地理位置信息。在R14 V2X中,当UE处于网络覆盖(连接态或空闲态),UE使用网络配置的资源,当UE处于无覆盖,使用预配置的资源;此外,UE可以被配置operator-managed sidelink通信资源和或non-operator managed sidelink通信资源,当UE处于限制服务状态时可使用non-operator managed资源, 当UE处于某些条件下(在所选PLMN没找到suitable cell,或在注册请求时收到PLMN不允许的响应,或在注册请求时收到GPRS不允许的响应)的限制服务状态时也可使用operator managed资源,而其他条件下的限制服务状态不可使用operator managed资源。或者某些区域没有配置operator managed资源,UE只能使用预配置的non-operator managed资源。考虑覆盖及资源配置优化,UE可记录使用基站配置资源、预配置资源、运营商管理资源、非运营商管理资源、检测到的限制服务状态或使用的资源类型发生变化时的时间及地理位置信息。如,当UE使用non-operator managed资源时可以记录相关信息,UE从operator managed资源切换到non-operator managed资源时的时间及地理位置信息,持续使用non-operator managed资源的时间,持续使用non-operator managed资源的行驶距离/路程/线路,UE从non-operator managed资源切换到operator managed资源时的时间及地理位置信息,使用non-operator managed资源的原因(如没有配置的operator managed资源,或某种限制服务状态)。当UE可上报测量记录信息时(进入连接态,或有可为其转发测量报告信息给基站的UE或RSU,并满足上报条件),UE将测量记录信息报告给网络侧。网络侧可考虑优化该地理区域网络覆盖或sidelink通信资源配置等。
M4:移动性测量,指记录在划分的地理区域zone内的行驶或停留时间信息。在R14 V2X中,UE可以使用基于地理位置区域划分(zone-based)而关联的sidelink资源池,网络可以配置或者通过预配置信息配置zone的划分规则,基于此规则划分的zone大小都相等。但是有些区域内可能UE数量较多,而有些区域UE数量较少,zone的划分规则可能并不合理。可以考虑UE记录在每个zone内行驶信息,如,当前zone标识,zone的地理信息,进入zone的时间,驶离zone的时间,在zone内行驶/停留时间(可通过zone内行驶时间大致判断zone内车辆密集程度)。当UE满足上报条件或当基站请求UE上报zone测量结果信息时,UE上报zone测量结果,基站/网络基于zone测量结果信息,可考虑优化配置某些地理区域zone的划分规则,或对于不同的地理区域配置不同的划分规则,或对于车辆密集的zone可配置多个sidelink资源池,或其他网络优化或调度优化措施。
M5:同步测量,指记录UE使用的同步源类型或同步源类型变化信息。在R14 V2X中有演进型基站(evolved NodeB,eNB)、全球导航卫星***(Global Navigation Satellite System,GNSS)和UE三种同步源类型,小区配置和预配置信息中可配置同步源的优先级,即优先使用哪种同步源类型进行同步。不同的同步参考的定时可能不对齐,定时不对齐会不利于相邻UE的sidelink通信。可以考虑当UE同步源类型发生变化时,UE记录同步源变化信息,如,同步源变化的时间、地理位置、原来使用的同步源类型、当前使用的同步源类型。网络 可以基于同步源测量信息,优化不同小区、不同地理区域、不同时间段配置或预配置信息中的优先同步源类型。
M6:半静态资源使用情况测量。在R14 V2X中,可为UE配置和激活多个sidelink SPS配置。可以考虑UE检测记录每个SPS配置资源的使用情况以辅助基站优化SPS配置,检测记录信息如,SPS index,UE是否从该组SPS资源的第一个资源开始使用,UE第一次使用该组SPS资源的资源位置,UE等待该组SPS资源的时间偏移量,该组SPS资源中哪些资源UE未使用,一段时间内/测量周期内该组SPS资源中未被使用资源的比例(该段时间内,SPS index 1中,未被使用的SPS资源与总的SPS资源的比值),UE连续使用该组SPS资源的时间/资源数量。
M7:信道质量测量。sidelink同步信道/发现信道/控制信道/数据信道的参考信号接收质量(Reference Singnal Received Quality,RSRQ)/参考信号接收功率(Reference Singnal Received Power,RSRP)/旁路链路接收信号强度指示(Sidelink-Received Singnal Strengthen Indicator,S-RSSI)/信躁比(Signal to Interference and Noise Ratio,SINR)测量,进一步的,基于波束(同步信号块(Synchronization signal block,SSB)或信道状态信息参考信号(Channel state information reference signal,CSI-RS)或sidelink测量信号)的RSRQ/RSRP/S-RSSI/SINR测量。
M8:sidelink QoS测量,包括以下至少之一:基于sidelink数据信道PSSCH或sidelink控制信道PSCCH的误块率BLER测量;基于源目标对之间sidelink逻辑信道或sidelink承载或优先级PPPP或可靠性PPPR或5QI的数据量data volume、或吞吐量throughput、或包延迟packet delay、或丢包率packet loss rate或packet discard rate的测量。比如,发送端data volume为测量周期内从分组数据汇聚协议(Packet Data Convergence Protocol,PDCP)层发给无线链路层控制协议(Radio Link Control,RLC)层的PDCP服务数据单元(Service Data Unit,SDU)比特数,发送端data volume的测量为基于源目标对之间sidelink逻辑信道或sidelink承载或优先级PPPP或可靠性PPPR或5QI进行的测量;接收端data volume为测量周期内成功接收的PDCP SDU比特数,接收端data volume的测量为基于源目标对之间sidelink逻辑信道或sidelink承载或优先级PPPP或可靠性PPPR或5QI进行的测量;packet discard rate为测量时间T内,基于源目标对之间sidelink逻辑信道或sidelink承载或优先级PPPP或可靠性PPPR或5QI,PDCP层、RLC层及媒体接入控制(Medium Access Control,MAC)层被丢弃的没有在PC5接口传输的数据包(不是由于切换原因导致的)与进入PDCP上一服务接入点(upper Service Accessing point,upper SAP)的总的数据包的比值;packet loss rate为时间T内,基于源目标对之间sidelink逻辑信道或sidelink承载或优 先级PPPP或可靠性PPPR或5QI,传输到上层丢失的PDCP序列号(Serial Number,SN)数与传递到上层的总的PDCP SN数(时间T内最后传递到上层的PDCP SN号减去最初传递到上层的PDCP SN号)的比值;packet delay为测量时间T内,基于源目标对之间sidelink逻辑信道或sidelink承载或优先级PPPP或可靠性PPPR或5QI,packet PDCP queuing delay(数据包到达PDCP upper SAP到开始传递到RLC层的时间)超过配置的delay threshold的packet(PDCP SDU)数与总的packet数的比例。

此外,可以考虑UE从路侧单元或中继节点或本地管理终端或群组管理终端获取sidelink路测配置信息。
步骤2:UE执行sidelink通信路测测量,获取sidelink路测信息并保存。Sidelink路测信息包括以下至少之一:Sidelink资源池拥塞测量信息,sidelink资源池资源冲突信息,覆盖测量信息,移动测量信息,同步测量信息,半静态资源使用信息,sidelink服务质量QoS测量信息,sidelink信道质量测量信息,测量时间相关信息,测量或记录时刻的地理位置信息,sidelink通信业务信息,终端行驶信息。

图4为本发明实施例中UE自主进行sidelink路测的方法的流程图,该方法主要应于车联网UE根据预设sidelink路测配置信息进行sidelink路测信息获取的情况,在本实施例中,配置侧包括:基站、中继节点和RSU。
对于车联网UE,UE节电与存储并不是重要的考虑因素,并且UE在无网络覆盖时也应能进行sidelink通信,因此可以考虑UE路测并不由网络控制,而是UE可以基于预配置信息自主进行sidelink通信路测。该方式可适用于任意连接状态的UE(连接态UE、空闲态UE、inactive UE、无覆盖UE)。预配置的sidelink路测配置信息与上述基站配置的sidelink路测配置信息内容一样。UE记录sidelink路测信息(即sidelink路测测量结果信息),当UE具备上报条件时(UE意愿或UE满足上报条件或UE进入连接态),UE发送sidelink路测信息记录指示给基站,如果基站对UE路测信息感兴趣,则发送sidelink路测信息上报请求消息给UE,请求UE发送sidelink路测信息;UE接收到请求后,发送sidelink路测信息给基站。Sidelink路测信息内容与上述实施例中一致,不再赘述。图4为上述流程示意图。其中,sidelink路测信息记录指示可通过RRC Connection Reconfiguration Complete、RRC Connection Reestablishment Complete、RRC Connection Setup Complete、RRC Connection Resume Complete、sidelink UE Information消息来携带;sidelink路测信息上报请求可通过UE Information Request消息来携带;sidelink路测信息上报可通过UE Information Response、sidelink UE Information消息来携带。
对于覆盖外的UE,虽然实时性差,但是可以考虑用于网络优化,或者用于其他UE行驶到该区域附近的QoS预测或提前应对(比如提前将通过Uu口传输的某些V2X业务切换到PC5接口传输,保证服务连续性及基本QoS保障;提前准备切换资源模式/切换资源池等,提前进行sensing、资源冲突检测;以及提前进行应用层的一些应对措施等),因此可以考虑覆盖外UE进行sidelink测量记录。
此外,对于无覆盖UE,也可以通过有覆盖中继节点(UE)或RSU(UE类型或基站类型)将sidelink路测信息转发给网络。UE发送sidelink路测信息记录指示给中继节点或RSU,若中继节点或RSU可以为其转发,则发送sidelink路测信息上报请求给UE,UE将sidelink路测信息发送给中继节点或RSU,之后中继节点或RSU可将sidelink路测信息发给网络或车联网信息处理中心;可选的,中继节点或RSU向基站指示有覆盖外UE有sidelink路测信息记录,若基站同意则发送sidelink路测信息上报请求给中继节点或RSU,中继节点或RSU 将该请求信息转发给UE,UE发送sidelink路测信息给中继节点或RSU,并经其转发给基站。或者考虑UE将sidelink路测信息发送给本地/群组管理终端或邻近服务终端。
通过上述实施例,实现了在没有网络覆盖时也应能进行sidelink通信,同时将sidelink路测信息进行及时上报。
实施例五:
本实施例提供空闲态UE、inactive UE获取sidelink路测配置信息的另一种方式。
如图5所示,UE在连接态时,网络通过专用路测配置消息(如Log Measurement Configuration)发送sidelink路测配置信息给UE,除了现有路测日志配置信息中包含的测量区域范围、配置持续时间和/或记录间隔外,还可以包含sidelink路测特有的配置信息,包含一种或多种但不限于以下内容,如sidelink测量记录指示(用于指示终端进行sidelink业务测量记录),sidelink测量业务类型,sidelink测量项(指示测量记录哪些sidelink路测项),sidelink测量频率等。
UE接收sidelink日志路测配置信息后,进行本地保存和处理。当UE在idle态或inactive态配置开始生效时执行sidelink测量,并记录保存。UE检查当前所处区域是否满足配置范围,只有在配置有效区域范围内进行sidelink测量记录。当UE进入连接态后,向基站指示sidelink路测信息记录,基站根据自身情况请求获取UE的sidelink路测信息,UE收到基站请求后,发送记录的sidelink路测信息。
实施例六:
本实施例,适用于第一核心配置侧为网管或移动性管理单元(Mobility Management Entity,MME)/接入管理功能(Access Management Function,AMF)的情况。
本实施例提供一种利用最小化路测(Minimization of Drive-tests,MDT)机制实现sidelink路测配置激活及上报流程。如图6所示,有如下两种激活方式:
(1)AMF通过下一代(Next Generation,NG)接口发送sidelink路测激活信息给服务于某终端的gNB。AMF可以通过INITIAL CONTEXT SETUP REQUEST、TRACE START、NG HANDOVER REQUEST消息或新增消息将 sidelink路测激活信息下发给基站,其中,sidelink路测激活信息,包含以下至少之一:sidelink路测指示(用于指示终端进行sidelink路测,可指示进行及时路测和或日志路测),sidelink QoS预测目的指示,sidelink测量项(如Sidelink资源池拥塞测量,sidelink资源池资源冲突测量,覆盖测量,移动测量,同步测量,SPS使用情况测量,sidelink QoS测量,sidelink信道质量测量),sidelink测量业务类型,trace标识,PLMN列表,日志持续时间,日志间隔,测量周期,上报周期,上报触发,事件阈值。基站收到sidelink路测激活信息后,根据激活信息发送sidelink路测配置信息给UE(如实施例三)。基站接收UE上报的sidelink路测信息,进行本地处理或发送给TCE(Trace Collection Entity)或发送给V2X服务器或V2X管理网元或接入网侧集中数据处理中心。接收UE上报sidelink路测信息的基站和下发sidelink路测配置信息的基站可能相同也可能不同。
如果是E-UTRAN***,则是MME通过S1接口相关消息(如INITIAL CONTEXT SETUP REQUEST、TRACE START、S1HANDOVER REQUEST等)发送sidelink路测激活信息给eNB。
(2)网管(element manager)发送sidelink路测激活信息给基站,sidelink路测激活信息可通过trace session activation消息或其它新定义的消息携带。sidelink路测激活信息,包含以下至少之一:sidelink路测指示(用于指示终端进行sidelink路测,可指示进行及时路测和或日志路测),sidelink测量项(如Sidelink资源池拥塞测量,sidelink资源池资源冲突测量,覆盖测量,移动测量,同步测量,SPS使用情况测量,sidelink QoS测量,sidelink信道质量测量),sidelink测量业务类型,trace标识,PLMN列表,日志持续时间,日志间隔,测量周期,上报周期,上报触发,事件阈值。基站收到sidelink路测激活信息后,根据激活信息、UE能力信息和或测量区域信息等,选择合适的UE进行sidelink路测,并发送sidelink路测配置信息给所选择的UE(如实施例三)。基站接收UE上报的sidelink路测信息,进行本地处理或发送给TCE(Trace Collection Entity)或发送给V2X服务器或V2X管理网元或接入网侧集中数据处理中心。
此外,当UE从源gNB通过Xn切换到目标gNB,源基站要将UE的sidelink路测激活信息或sidelink路测配置信息发给目标基站(handover request)。如果是NG接口切换,AMF将UE的sidelink路测激活信息发给新基站(NG HANDOVER REQUEST)。当UE在原来的基站进入inactive状态并与新基站建立RRC连接,新基站在Xn接口发起Retrieve UE Context procedure,原来的基站通过RETRIEVE UE CONTEXT RESPONSE消息将UE的sidelink路测激活信息或sidelink路测配置信息发给新基站。
实施例七:
本实施例,适用于第二核心配置侧为核心网网元MME/AMF的情况。
本实施例提供一种sidelink路测意愿信息下发的方法流程。如图7所示,
核心网网元发送UE的sidelink路测意愿信息(作为UE上下文一部分)给接入网网元,其中,sidelink路测意愿信息包括以下至少之一:执行sidelink路测意愿(是否愿意执行sidelink路测),上报sidelink路测信息意愿(是否愿意上报sidelink路测结果/记录信息),及时/立即sidelink路测意愿(immediate MDT),sidelink路测日志记录意愿(logging MDT),sidelink路测通信类型意愿(广播、单播、组播),适用范围PLMN列表等。接入网网元接收UE sidelink路测意愿信息并保存到UE上下文信息中。当接入网网元接收到sidelink路测激活信息,接入网网元根据sidelink路测激活信息及UE sidelink路测意愿信息及其它信息选择合适的UE进行sidelink路测。
在E-UTRAN***中,接入网网元为eNB,核心网网元为MME;在5G***中,接入网网元为gNB,核心网网元为AMF。当发生S1/NG切换,MME/AMF将UE的sidelink路测意愿信息发送给目标基站(如S1/NG Handover request消息)。当发生X2/Xn切换,源基站将UE的sidelink路测意愿信息发送给目标基站(如通过X2/Xn Handover request或PATH SWITCH REQUEST ACKNOWLEDGE消息)。当UE在原来的基站进入inactive状态并与新基站建立RRC连接,新基站在Xn接口发起Retrieve UE Context procedure,原来的基站通过RETRIEVE UE CONTEXT RESPONSE消息将UE的sidelink路测意愿信息发给新基站。
实施例八:
一种直通链路服务质量管理方法,包括:
基站从接入移动管理功能实体获取UE PC5 QoS相关参数。
基站依据所述UE PC5 QoS相关参数进行sidelink通信配置。
其中,UE PC5 QoS相关参数包括以下至少之一:UE-PC5-最大聚合比特率(Aggregated Maximum Bit Rate,AMBR),PC5 QoS rules,PC5 QoS flow列表,PC5 QoS flow对应的5QI、V2X业务服务质量标识、分配保留优先级ARP、流保证比特率(Guaranteed Flow Bit Rate,GFBR)、最大比特速率(Maximum Flow Bit Rate,MFBR)、镜像QoS指示。
在所述基站从接入移动管理功能实体获取UE PC5 QoS相关参数之前或之 后,进一步包括:基站接收终端发送的PC5通信请求/sidelink通信资源请求。
其中,PC5通信请求/sidelink通信资源请求包括以下至少之一:5QI,PC5接口服务质量标识,V2X业务服务质量标识,QoS流标识QFI,包优先级,延时,可靠性,数据率,发送频率,传输范围,可用频点。
基站依据所述UE PC5 QoS相关参数进行sidelink通信配置,包括基站对PC5通信请求进行接纳控制,并发送sidelink通信配置信息给UE。其中,sidelink通信配置信息包括以下至少之一:接纳的PC5 QoS flow list,PC5 QoS flow与sidelink承载/逻辑信道的映射关系,UE-PC5-AMBR,PC5 QoS flow抢占指示。
请参照图8,如图8所示为本实施例UE PC5 QoS管理流程的示意图。
在5G***中,NR PC5接口可以考虑基于QoS flow的QoS机制,类似于5G Uu QoS机制。UE预配置有PC5 QoS rules,根据QoS rules将V2X packet映射到PC5 QoS flows。基站从核心网(AMF)获取UE PC5 QoS相关参数,如PC5 QoS rules,UE PC5接口最大聚合比特率UE-PC5-AMBR,PC5 QoS flow列表,PC5 QoS flow对应的5QI、分配保留优先级ARP,ARP指示该QoS flow资源请求的相对优先级、是否具备抢占资源能力、以及是否可被抢占资源;进一步地,PC5 QoS flow可支持保证比特速率(Guaranteed Bit Rate,GBR)QoS flow及非保证比特速率(non-Guaranteed Bit Rate,non-GBR)QoS flow,对于GBR QoS flow进一步可包含GFBR和MFBR,对于non-GBR QoS flow进一步可包含镜像QoS指示,指示QoS flow在PC5接口是否支持镜像映射。基站将获取的UE PC5 QoS相关参数保存到UE上下文中。需要注意的是,基站从核心网获取UE PC5相关参数,可以在基站收到UE发送的PC5通信请求/资源请求之后向核心网获取,如基站发送UE PC5通信信息(包括以下至少之一:PC5 QoS flow标识QFI,5QI,PC5接口服务质量标识,V2X业务服务质量标识,包优先级,延时,可靠性,)给AMF。
当UE在PC5接口有数据要发送(进行V2X sidelink通信),UE向基站发送PC5通信请求/请求资源时,可以将待发送数据PC5 QoS信息上报给基站,PC5 QoS信息包括以下至少之一:5QI,PC5接口服务质量标识,V2X业务服务质量标识,QoS流标识QFI,包优先级,延时,可靠性,数据率,发送频率,传输范围,可用频点;PC5 QoS信息可通过sidelink UE Information、UE assistance Information或其他用于指示sidelink通信相关信息的消息发送。基站收到UE的sidelink通信资源请求时,依据待发送数据QoS信息及UE上下文中PC5 QoS相关参数,决定是否接纳PC5 QoS flow传输并为其分配sidelink通信资源,例如,基站基于UE上下文中PC5 QoS flow的ARP信息以及当前sidelink资源使用情况,决定是否接纳某个PC5 QoS flow的传输,如果接纳,可进一步配置PC5 QoS flow与sidelink承载/逻辑信道的映射关系,如果没有合适的sidelink承载/逻辑信道,则为UE配置sidelink承载配置信息。基站将接纳的PC5 QoS flow list及PC5 QoS flow与sidelink承载/逻辑信道的映射关系发送给UE。对于基站调度模式,基站基于UE-PC5-AMBR为UE调度资源。此外,对于UE自主选择资源模式,基站可进一步指示每个PC5 QoS flow是否可被抢占和或是否允许被抢占,那么当UE资源池拥塞时,可据此满足高优先级及可抢占资源的PC5 QoS flow的传输。
此外,当发生NG切换,AMF将UE的PC5 QoS相关参数发送给目标基站(如NG Handover request消息)。当发生Xn切换,源基站将UE的PC5 QoS相关参数发送给目标基站(如通过Xn Handover request或PATH SWITCH REQUEST ACKNOWLEDGE消息)。当UE在原来的基站进入inactive状态并与新基站建立RRC连接,新基站在Xn接口发起Retrieve UE Context procedure,原来的基站通过RETRIEVE UE CONTEXT RESPONSE消息将UE的PC5 QoS相关参数发给新基站。
