具体实施方式
为使本申请的目的、技术方案和优点更加清楚,下面将结合附图对本申请实施方式作进一步地详细描述。
这里将详细地对示例性实施例进行说明,其示例表示在附图中。下面的描述涉及附图时,除非另有表示,不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本申请相一致的所有实施方式。相反,它们仅是与如所附权利要求书中所详述的、本申请的一些方面相一致的装置和方法的例子。
本申请实施例描述的网络架构以及业务场景是为了更加清楚地说明本申请实施例的技术方案,并不构成对本申请实施例提供的技术方案的限定,本领域普通技术人员可知,随着网络架构的演变和新业务场景的出现,本申请实施例提供的技术方案对于类似的技术问题,同样适用。
在本公开使用的术语是仅仅出于描述特定实施例的目的,而非旨在限制本公开。在本公开和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式,除非上下文清楚地表示其他含义。还应当理解,本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解,尽管在本公开可能采用术语第一、第二等来描述各种信息,但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如,在不脱离本公开范围的情况下,第一参数也可以被称为第二参数,类似地,第二参数也可以被称为第一参数。取决于语境,如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
车联网通信包括车与车(Vehicle to Vehicle,V2V)通信、车与路侧基础设施(Vehicle to Infrastructure,V2I)通信以及车与行人(Vehicle to People,V2P)通信。通过支持V2V通信、V2I通信以及V2P通信,车联网可以有效提升交通安全,改善交通效率以及丰富出行体验。
利用现有的蜂窝通信技术支持车联网通信,可以有效利用已部署的基站,减少设备开销,以及有利于提供具有服务质量(Quality of Service,QoS)保证的服务,从而能够满足车联网业务的需求。
在长期演进(Long Term Evolution,LTE)的R14(Release14)/R15(Release15)中,实现了通过蜂窝网络支持车联网通信,具体指基于蜂窝的车联网(Cellular based V2X,C-V2X)技术。在C-V2X中,车载设备(例如车载终端)和其他设备之间的通信可以通过基站以及核心网设备进行中转,即利用原有蜂窝网络中终端和基站之间的通信链路实现车载设备和其他设备之间通信(包括上行链路(UpLink,UL)通信以及下行链路(DownLink,DL)通信)。车载设备和其他设备也可以直接通过设备间的直连链路(也称侧行链路(sidelink))进行通信。
侧行链路通信是一种设备到设备的通信方式,具有较高的频谱效率和较低的传输时延。侧行链路具有两种传输模式,第一种传输模式为:网络设备为终端(车载设备)分配传输资源,终端在分配的传输资源上进行侧行链路的数据传输。第二种传输模式为:网络设备为终端分配资源池,终端在资源池中自行选取一个或多个传输资源进行侧行链路的数据传输。示例性的,终端可以通过侦听的方式在资源池中选择传输资源,或者,通过随机选取的方式在资源池中选取传输资源。与Uu接口通信相比,侧行链路通信具有时延短,开销小等特点,非常适合用于车载设备和地理位置接近的其他周边设备进行直接通信。
随着5G移动通信技术的发展,在第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)的R16中提出了利用5G新空口(New Radio,NR)技术来实现对新的车联网通信的服务和场景的支持,例如支持车队管理(Vehicles Platooning),感知扩展(Extended Sensors),先进驾驶(Advanced Driving),和 远程驾驶(Remote Driving)等。总体来说,5G V2X sidelink能够提供更高的通信速率,更短的通信延时,更可靠的通信质量。
图1示出了本申请一个示例性实施例提供的SL通信网络架构的示意图。该SL通信网络架构可以包括:核心网11、接入网12和终端13。
核心网11中包括若干核心网设备。核心网设备的功能主要是提供用户连接、对用户的管理以及对业务完成承载,作为承载网络提供到外部网络的接口。例如,第五代移动通信技术(5th Generation,5G)NR***的核心网中可以包括接入和移动性管理功能(Access and Mobility Management Function,AMF)实体、用户平面功能(User Plane Function,UPF)实体和会话管理功能(Session Management Function,SMF)实体等设备。
接入网12中包括若干接入网设备14。5G NR***中的接入网可以称为新一代无线接入网(New Generation-Radio Access Network,NG-RAN)。接入网设备14是一种部署在接入网12中用以为终端13提供无线通信功能的装置。接入网设备14可以包括各种形式的宏基站,微基站,中继站,接入点等等。在采用不同的无线接入技术的***中,具备接入网设备功能的设备的名称可能会有所不同,例如在5G NR***中,称为5G基站(Next Generation Node B,gNodeB或gNB)。随着通信技术的演进,“接入网设备”这一名称可能会变化。为方便描述,本公开实施例中,上述为终端13提供无线通信功能的装置统称为接入网设备。
终端13的数量通常为多个,每一个接入网设备14所管理的小区内可以分布一个或多个终端13。终端13可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备,以及各种形式的用户设备、移动台(Mobile Station,MS)等等。为方便描述,上面提到的设备统称为终端。接入网设备14与核心网设备之间通过某种空中技术相互通信,例如5G NR***中的NG接口。接入网设备14与终端13之间通过某种空中技术互相通信,例如Uu接口。
终端13和终端13(例如车载设备与其它设备(如其它车载设备、手机、路侧单元(Road Side Unit,RSU)等))之间可以通过直连通信接口(如PC5接口)互相通信,相应地,该基于直连通信接口建立的通信链路可以称为直连链路或SL。SL传输即为终端与终端之间通过侧行链路直接进行通信数据传输,不同于传统的蜂窝***中通信数据通过接入网设备接收或者发送,SL传输具有时延短、开销小等特点,适合用于地理位置接近的两个终端(如车载设备和地理位置接近的其它周边设备)之间的通信。需要说明的是,在图1中,仅以V2X场景下的车对车通信为示例,SL技术可以应用于各种终端之间直接进行通信的场景。或者说,本申请中的终端是指任意一种利用SL技术通信的设备。
本公开实施例中的“5G NR***”也可以称为5G***或者NR***,但本领域技术人员可以理解其含义。本公开实施例描述的技术方案可以适用于5G NR***,也可以适用于5G NR***后续的演进***。
本公开实施例中的UE与终端表达同一含义,两者可以相互替换。
在侧行链路通信中,根据进行通信的终端所处的网络覆盖情况,可以分为网络覆盖内侧行通信、部分网络覆盖侧行通信和网络覆盖外侧行通信。
图2示出了网络覆盖内SL通信网络架构的示意图。所有进行侧行通信的终端13均处于同一接入网设备14的覆盖范围内,所有终端13均可以通过接收接入网设备14的配置信令,基于相同的侧行配置进行侧行通信。
图3示出了部分网络覆盖SL通信网络架构的示意图。进行侧行通信的第一终端131位于基站的覆盖范围内,第一终端131能够接收到接入网设备14的配置信令,并根据接入网设备14的配置进行侧行通信。位于网络覆盖范围外的第二终端132,无法接收接入网设备14的配置信令,在这种情况下,网络覆盖范围外的第二终端132将根据预配置(pre-configuration)信息及位于网络覆盖范围内的第一终端131发送的侧行广播信道(Physical Sidelink Broadcast Channel,PSBCH)中携带的信息确定侧行配置,进行侧行通信。
图4示出了网络覆盖外SL通信网络架构的示意图。所有进行侧行通信的终端13均位于网络覆盖范围外,所有终端13均根据预配置信息确定侧行配置进行侧行通信。
关于SL传输,3GPP定义了两种传输模式:模式A和模式B。
模式A(又称模式1或基站调度模式):终端的传输资源是由接入网设备(如基站)分配的,终端根据接入网设备分配的传输资源在侧行链路上进行通信数据的传输,其中,接入网设备既可以为终端分配单次传输的传输资源,也可以为终端分配半静态传输的传输资源。
模式B(又称模式2或UE自主选择资源模式):终端自行在资源池中选取传输资源进行通信数据的传输。具体地,终端可以通过侦听的方式在资源池中选取传输资源,或者通过随机选取的方式在资源池中选取传输资源。
NR V2X***中SL通信的物理层结构如图5所示。物理侧行控制信道(Physical Sidelink Control Channel,PSCCH)用于承载第一侧行控制信息,物理侧行共享信道(Physical Sidelink Shared Channel,PSSCH)用于承载数据和第二侧行控制信息。PSCCH和PSSCH在同一时隙中发送。上述第一侧行控制信息和第二侧行控制信息可以是两个具有不同作用的侧行控制信息。例如,第一侧行控制信息承载在PSCCH中,主要包含资源侦听相关的域,方便其他终端解码后进行资源排除与资源选择。在PSSCH中,除了数据外,还承载第二侧行控制信息,第二侧行控制信息主要包括数据解调相关的域,方便其他终端解调该PSSCH中的数据。
在NR V2X***中,上述模式B下,终端自行选择传输资源来发送数据。资源预留则是资源选择的前提。
资源预留是指终端在PSCCH中发送第一侧行控制信息预留接下来要使用的资源。在NR V2X***中,支持传输块(Transport Block,TB)内的资源预留也支持TB间的资源预留。
接下来,对DRX机制进行介绍:
在无线网络中,用户终端(User Equipment,UE)要一直监听物理下行控制信道(Physical Downlink Control Channel,PDCCH),根据网络侧发送的指示消息对数据进行收发,这样导致UE的功耗和数据传输的时延都比较大。因此3GPP标准协议在LTE***中开始引入非连续接收机制(Discontinuous Reception,DRX)节能策略。
DRX的基本机制是为UE配置一个DRX周期。DRX周期由激活时间段和DRX机会(Opportunity for DRX)组成:在激活时间段内,UE监听并接收PDCCH;在DRX机会时间内,UE不接收PDCCH以减少功耗。
在DRX操作中,终端根据网络配置的一些定时器参数来控制终端处于激活状态或者休眠状态。
例如,通过drx-onDurationTimer参数指示激活时间段的长度,通过drx-LongCycleStartOffset参数和drx-SlotOffset参数指示DRX周期的起始位置。终端根据上述参数,在DRX周期的起始位置启动长度为drx-onDurationTimer参数指示的值的定时器,在定时器减为0前,保持激活状态。
当终端在激活时间段内,即On duration timer减到0之前,如果终端检测到PDCCH,还会启动非激活(Inactivity)计时器、重传(Re-transmission)计时器等定时器延长激活状态,用于接收调度的数据或者重传。
图6示出了DRX周期的示意图,一个DRX周期11中包括激活时间段12和DRX机会13。

综上所述,本实施例提供的方法,通过引入唤醒或休眠信号指示终端是否进行侧行链路信号检测,丰富了终端进行侧行链路信号检测的控制机制,唤醒或休眠信号将是否进行侧行链路信号检测与是否存在侧行数据联系起来,避免了在没有侧行数据发送的情况下,仍在激活时间段进行侧行链路信号检测的问题,节约了不必要的功耗。

示例性的,在本实施例中,调度信息用于调度第三时频资源。第三时频资源用于供第一终端向第二终端发送侧行数据。也即,第二SR所请求发送的侧行数据。在本申请的各个实施例中,第三时频资源可以在激活时间段内,也可以不在激活时间段内,对此不作出任何限制。可选的,第三时频资源包括至少一个激活时间段范围内的时频资源。
步骤562:第一终端接收网络设备的调度信息,确定第三时频资源;
第三时频资源用于供第一终端向第二终端发送侧行数据。

步骤564:网络设备在目标时间范围内的第二时频资源,向第二终端发送唤醒信号;
示例性的,第二时频资源为物理下行控制信道(Physical Downlink Control Channel,PDCCH)。
示例性的,唤醒信号的格式为下行控制信息格式。下行控制信息是承载在PDCCH中的控制信息。需要说明的是,随着移动通信技术的发展,下行控制信息可以出现新的信息格式,本申请中唤醒信号同样适用于新出现的信息格式。比如:唤醒信号是DCI格式2_6(Format 2_6)。
步骤566:第二终端在后续的T1个激活时间段进行侧行链路信号检测;
本步骤可以参考上文实施例中的步骤526,在本实施例中不再赘述。
步骤568:第一终端在第三时频资源向第二终端发送侧行数据;
本步骤可以参考上文实施例中的步骤528,在本实施例中不再赘述。
综上所述,本实施例提供的方法,引入唤醒信号指示终端进行侧行链路信号检测,将进行侧行链路信号检测与存在侧行数据联系起来,网络设备向第二终端发送唤醒信号,仅在有侧行数据发送的情况下,第二终端在激活时间段进行侧行链路信号检测,节约了不必要的功耗。
针对第一设备是网络设备,对不存在待传输的侧行数据的情况,即第一终端未向网络设备发送第二SR和/或第二BSR的情况进行介绍:

示例性的,休眠信号的格式为下行控制信息格式。下行控制信息是承载在PDCCH中的控制信息。需要说明的是,随着移动通信技术的发展,下行控制信息可以出现新的信息格式,本申请中休眠信号同样适用于新出现的信息格式。比如:休眠信号是DCI格式2_6(Format 2_6)。
步骤578:第二终端在后续的T2个激活时间段不进行侧行链路信号检测;
本步骤可以参考上文实施例中的步骤542,在本实施例中不再赘述。
综上所述,本实施例提供的方法,引入休眠信号指示终端不进行侧行链路信号检测,将不进行侧行链路信号检测与不存在侧行数据联系起来,网络设备向第二终端发送休眠信号,避免了在没有侧行数据发送的情况下,仍在激活时间段进行侧行链路信号检测的问题,节约了不必要的功耗。
