Description

资源选择方法、装置、设备及存储介质 技术领域
本申请实施例涉及通信技术领域,尤其涉及一种资源选择方法、装置、设备及存储介质。
背景技术
目前第三代合作伙伴计划(3rd generation partnership project,3GPP)在车到设备(vehicle to everything,V2X)技术中,定义了两种传输模式:一种是终端根据基站分配的资源在侧行链路上传输数据,基站可以为终端分配单次传输的资源,或者分配半静态传输的资源。另一种是终端根据现有的侦听流程确定候选资源集合,进而在候选资源集合中自主选取资源进行侧行传输。
上述第二种传输模式的侦听流程,需要终端持续的进行资源侦听,以判断哪些资源是可用的,终端能耗过大。为了达到节能目的,考虑在侧行链路(Sidelink,SL)系统引入非连续接收DRX机制,终端可根据DRX配置不连续的进行资源或数据的接收。
由于SL DRX技术的引入,可能存在终端之间发送数据或信令时,对方处于休眠状态的情况,影响整个系统的传输性能。因此,亟需对目前的资源选取方案作进一步优化,提高侧行通信系统的整体性能。
发明内容

第一方面,本申请实施例提供一种资源选择方法,应用于第一设备,该方法包括:根据一个或多个第二设备的非连续接收DRX配置信息,选择用于侧行传输的一个或多个资源。
第二方面,本申请实施例提供一种资源选择装置,包括:处理模块,用于根据一个或多个第二设备的非连续接收DRX配置信息,选择用于侧行传输的一个或多个资源。
第三方面,本申请实施例提供一种电子设备,包括:收发器、处理器、存储器;所述存储器存储计算机执行指令;所述处理器执行所述存储器存储的计算机执行指令,使得所述处理器执行如第一方面所述的方法。

具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚,下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
本申请实施例的说明书、权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象,而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换,以便这里描述的本申请的实施例能够以除了在这里图示或描述之外的顺序实施。此外,术语“包括”和“具有”以及他们的任何变形,意图在于覆盖不排他的包含,例如,包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元,而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
应理解,在本申请的实施例中提到的“指示”可以是直接指示,也可以是间接指示,还可以是表示具有关联关系。举例说明,A指示B,可以表示A直接指示B,例如B可以通过A获取;也可以表示A间接指示B,例如A指示C,B可以通过C获取;还可以表示A和B之间具有关联关系。
在本申请实施例的描述中,术语“对应”可表示两者之间具有直接对应或间接对应的关系,也可以表示两者之间具有关联关系,也可以是指示与被指示、配置与被配置等关系。
与传统的蜂窝系统中通信数据通过基站接收或者发送的方式不同,设备到设备(Device-to-Device,D2D)通信引入侧行链路(Sidelink,SL)传输技术,采用终端到终端直接通信的方式,因此具有更高的频谱效率以及更低的传输时延。
3GPP在LTE D2D/V2X中定义了两种传输模式:模式3和模式4。
模式3:终端的传输资源是由基站分配的,终端根据基站分配的资源在侧行链路上进行数据的发送;基站可以为终端分配单次传输的资源,也可以为终端分配半静态传输的资源。
模式4:车载终端在资源池中选择一个资源进行数据的传输。
在3GPP中,D2D分成了不同的阶段进行研究。
1)邻近服务(Proximity Service,ProSe):在Rel-12/13中设备到设备通信,是针对ProSe的场景进行了研究,其主要针对公共安全类的业务。在ProSe中,通过配置资源池在时域上的位置,例如资源池在时域上非连续,达到UE在侧行链路上非连 续发送/接收数据,从而达到省电的效果。
2)车联网(V2X):在Rel-14/15中,车联网系统针对车车通信的场景进行了研究,其主要面向相对高速移动的车车、车人通信的业务。在V2X中,由于车载系统具有持续的供电,因此功率效率不是主要问题,而数据传输的时延是主要问题,因此在系统设计上要求终端设备进行连续的发送和接收。
3)可穿戴设备(FeD2D):在Rel-14中,这个场景对于可穿戴设备通过手机接入网络的场景进行了研究,其主要面向是低移动速度以及低功率接入的场景。在FeD2D中,在预研阶段3GPP结论为基站可以通过一个中继终端(relay UE)去配置远端终端(remote UE)的非连续接收DRX参数,但是由于该课题没有进一步进入标准化阶段,如何进行DRX配置的具体细节没有结论。
在介绍本申请实施例提供的技术方案之前,首先对本申请实施例可能的应用场景进行说明。
示例性的,图1为本申请实施例提供的一种应用场景示意图。图1所示的通信系统中包括一个网络设备101以及两个终端设备,分别为终端设备102和103,终端设备102和终端设备103均处于网络设备101的覆盖范围内。网络设备101分别与终端设备102、终端设备103通信连接,终端设备102与终端设备103通信连接。示例性的,终端设备102可以通过网络设备101向终端设备103发送通信消息,终端设备102还可以直接向终端设备103发送通信消息。其中,终端设备102与终端设备103之间直接通信的链路称为D2D链路,也可以称为临近服务(proximity service,ProSe)链路、侧行链路等。D2D链路上的传输资源可以由网络设备分配。
示例性的,图2为本申请实施例提供的另一种应用场景示意图。图2所示的通信系统同样包括一个网络设备101以两个终端设备,与图1不同的是,终端设备103处于网络设备101的覆盖范围内,终端设备104在网络设备101的覆盖范围之外。网络设备101与终端设备103通信连接,终端设备103与终端设备104通信连接。示例性的,终端设备103可以接收网络设备101发送的配置信息,根据配置信息进行侧行通信。由于终端设备104无法接收网络设备101发送的配置信息,终端设备104可以根据预配置(pre-configuration)信息以及终端设备103发送的侧行广播信道(Physical Sidelink Broadcast Channel,PSBCH)中携带的信息,进行侧行通信。

需要说明的是,本申请实施例描述的系统架构以及应用场景是为了更加清楚的说明本申请实施例的技术方案,并不构成对于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问题,同样适用。
NR-V2X通信中,X可以泛指任意具有无线接收和发送能力的设备,包括但不限于慢速移动的无线装置,快速移动的车载设备,具有无线发射接收能力的网络控制节点等。NR-V2X通信支持单播、组播、广播的传输方式。对于单播传输,发送终端发送数据,接收终端只有一个。对于组播传输,发送终端发送数据,接收终端是一个通信组内的所有终端,或者是在一定传输距离内的所有终端。对于广播传输,发送终端发送数据,接收终端是发送终端周围的任意一个终端。
类似于LTE-V2X,NR-V2X也会定义mode-1/2两种传输模式:
第一传输模式mode-1:终端设备的传输资源是由基站分配的,终端设备根据基站分配的资源在侧行链路上进行数据传输。基站可以为终端设备分配单次传输的资源,也可以为终端设备分配半静态传输的资源。
示例性的,图1中终端设备102位于网络设备101覆盖范围内,网络设备101为终端设备102分配侧行传输使用的传输资源。
第二传输模式mode-2:终端设备如果具备侦听能力,可采用侦听和预留的方式传输数据或采用随机选择资源的方式传输数据。其中,侦听和预留的方式是指终端设备可以在网络配置或预配置的资源池中,通过侦听的方式获取可用的资源集合,从可用的资源集合中随机选择一个资源进行数据传输。终端设备如果不具备侦听能力,可直接在资源池中随机选择传输资源。
上述侦听是指终端设备接收其他终端设备发送的第一侧行控制信息,根据第一侧行控制信息的指示获知其他终端设备预留的资源,通过在资源选择时排除其他终端设备预留的资源,避免与其他终端设备发生资源碰撞。
示例性的,图1中终端设备102可以在网络配置的资源池中自主选择传输资源进行侧行传输。图3中终端设备104和105均位于网络设备101覆盖范围外,终端设备104和105可以在预配置的资源池中自主选择传输资源进行侧行传输。
在一些实施例中,终端设备可能处在一个混合的模式下,既可以使用mode-1进行资源的获取,又同时可以使用mode-2进行资源的获取。
不同于LTE V2X,除了无反馈的、UE自主发起的混合自动重传请求(Hybrid Automatic Repeat reQuest,HARQ),NR V2X引入了基于反馈的HARQ重传,即发送端设备可基于接收端设备的反馈信息判断是否需要进行数据重传。基于反馈的HARQ重传不限于单播通信,也包括组播通信。
与LTE-V2X相同,在NR-V2X中,由于车载系统具有持续的供电,因此功率效率不是主要问题,而数据传输的时延是主要问题,因此在系统设计上要求终端设备进行连续的发送和接收。
在NR-V2X中,一些新的特征被引入,比如支持大量非周期业务、重传次数的增多以及更灵活的资源预留周期等。这些特征都对终端自主资源选择的模式有较大影响。因此,3GPP以LTE-V2X中模式4为基础,重新讨论并设计了适用于NR-V2X mode-2的资源选择方案:UE通过解码其他UE发送的侧行控制信息SCI和测量侧行链路接收功率,在资源池中选择未被其他UE预留或者被其他UE预留但接收功率较低的资源。NR-V2X模式2的资源选择主要分为如下两个步骤:
步骤1、UE确定候选资源集合。
UE将资源选择窗内所有的可用资源作为资源集合A。首先,UE需根据资源侦听窗内的侦听结果,判断资源是否被其他UE预留。UE根据未侦听时隙与侦听到的第一阶SCI进行资源排除,在完成资源排除后,如果资源集合A中的剩余资源数目小于一定比例,UE将提升参考信号接收功率(Reference Signal Received Power,RSRP)阈值3dB,并重复执行步骤1直到资源集合A中的剩余资源数目大于等于该比例。相比较LTE-V2X中该比例固定为20%,NR-V2X中该比例的取值更为灵活,其可能的取值为{20%,35%,50%},具体比例的取值是以资源池为单位由网络配置或者预配置。最终,经过资源排除后的资源集合A即为UE的候选资源集合。
步骤2、UE在候选资源集合中选择传输资源。
UE在候选资源集合中等概率随机选择一个或多个传输资源。需要指出的是,在选择该多个传输资源时要满足如下时域上的限制:
第一,在除去一些例外情况后,UE应使选择的某个重传资源能够被之前发送的第一阶SCI指示。上述例外情况包括:UE在进行资源排除后,无法从候选资源集合中选择出满足该时域限制的资源。上述例外情况还包括:由于资源抢占、拥塞控制以及与上行业务冲突等因素,UE放弃传输从而导致某次重传的传输资源没有被之前发送的第一阶SCI指示。
第二,UE应保证任意两个选择的时频资源,如果其中前一个传输资源需要HARQ反馈,则这两个传输资源在时域上至少间隔时长Z。当资源选择无法满足该时域限制时,比如包延迟预算(Packet Delay Budget,PDB)较短但重传次数较多的情况下,取决于UE实现,可以放弃选择某些重传资源或者针对某几次传输去激活HARQ反馈。
在无线网络中,当有数据需要进行传输时,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标准协议中引入非连续接收机制(Discontinuous Reception,DRX)节能策略。
DRX的基本机制是为处于RRC_CONNECTED态的UE配置一个DRX周期(DRX cycle)。DRX cycle由“On Duration”和“Opportunity for DRX”组成:在“On Duration”时间内(又称为active time,激活期),UE监听并接收PDCCH;在“Opportunity for DRX”时间内(又称为inactive time,非激活期或休眠期),UE不接收PDCCH以减少功耗,相对于DRX on duration,Opportunity for DRX时间又可以称为DRX off duration。
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激活期和非激活期。例如,当UE在On Duration期间内接收到网络调度该UE的PDCCH时,该UE会激活计时器,如drx_inactiveTimer,在该计时器超时前,该终端处于激活状态。
UE根据DRX配置不连续的监控PDCCH以达到省电的目的,当PDCCH中携带与UE对应的C-RNTI,CI-RNTI,CS-RNTI,INT-RNTI,SFI-RNTI,SP-CSI-RNTI,TPC-PUCCH-RNTI,TPC-PUSCH-RNTI,TPC-SRS-RNTI和AI-RNTI时,UE会根据控制信息做出对应DRX操作。
网络通过配置一系列参数来控制UE的DRX行为,这些参数(Uu DRX参数)包 括:drx-onDurationTimer,drx-SlotOffset,drx-InactivityTimer,drx-RetransmissionTimerDL,drx-RetransmissionTimerUL,drx-LongCycleStartOffset,drx-ShortCycle(可选):the Short DRX cycle,drx-ShortCycleTimer(可选),HARQ-RTT-TimerDL,drx-HARQ-RTT-TimerUL,ps-Wakeup(optional),ps-TransmitOtherPeriodicCSI(可选),ps-TransmitPeriodicL1-RSRP(可选)。
其中,满足如下情况的至少一项时,UE将处于DRX激活状态:
drx-onDurationTimer或drx-InactivityTimer运行期间;
drx-RetransmissionTimerDL或drx-RetransmissionTimerUL运行期间;
ra-ContentionResolutionTimer或msgB-ResponseWindow运行期间;
有未被处理的资源调度请求(Scheduling Request,SR);
PDCCH指示有新的传输期间。
在NR-V2X mode-2的侦听流程,需要终端持续的进行资源侦听,以判断哪些资源是可用的,终端能耗过大。为了达到省电的目的,考虑在SL系统引入DRX机制。类似于上述Uu接口的DRX机制,终端在On duration范围内接收其他终端发送的数据,如果没有检测到数据,在DRX off duration范围内进入休眠状态,以节省功耗;如果检测到其他终端发给该终端的数据,终端会激活计时器,在计时器失效前,终端处于激活状态。本申请中DRX激活状态表示UE处于active状态,可接收来自其他UE的侧行数据(SCI),DRX非激活态表示UE处于inactive状态,跳过(不接收)来自其他UE的侧行数据(SCI)。
由于SL DRX技术的引入,发送端UE在选择资源时还需要考虑接收端UE的DRX配置。因此,亟需针对目前的资源选择方案作进一步优化,提高侧行通信系统的整体性能。
为了解决上述技术问题,本申请实施例提出一种资源选择方法,可以在资源选择过程中考虑增加根据接收端UE的DRX配置信息进行资源选择的步骤,该步骤可以增加在资源选择的第一步(资源排除)之前,也可以增加在资源选择的第一步之后,还可以增加在资源选择的第二步(资源预留)之后。若需要发送数据的接收端UE的数量为多个,还可以在资源选择过程中综合考虑多个接收端UE的DRX配置信息进行资源选择,提高侧行通信系统的传输性能。
