- the terminal controls the On Duration and Off Duration of the terminal according to some timer parameters configured by the network.
- the terminal in order to achieve the purpose of energy saving, it is considered to introduce a DRX mechanism in the SL, that is, SL DRX. Similar to the DRX mechanism of the Uu interface, the terminal receives data sent by other terminals within the On Duration range. If no data is detected, it enters the sleep state within the DRX Off Duration range to save power consumption. The duration of the terminal in the On Duration range is determined by the DRX configuration parameter drx_onDurationTimer.

图1是本申请实施例适用的一种通信***的示意图。车载终端(车载终端121和车载终端122)的传输资源是由基站110分配的,车载终端根据基站110分配的资源在侧行链路上进行数据的发送。具体地,基站110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。
图2是本申请实施例适用的另一种通信***的示意图。车载终端(车载终端131和车载终端132)在侧行链路的资源上自主选取传输资源进行数据传输。可选地,车载终端可以随机选取传输资源,或者通过侦听的方式选取传输资源。
需要说明的是,在侧行通信中,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,如图3所示;部分网络覆盖侧行通信,如图4所示;及网络覆盖外侧行通信,如图5所示。
图3:在网络覆盖内侧行通信中,所有进行侧行通信的终端均处于同一基站的覆盖范围内,从而,上述终端均可以通过接收基站的配置信令,基于相同的侧行配置进行侧行通信。
图4:在部分网络覆盖侧行通信情况下,部分进行侧行通信的终端位于基站的覆盖范围内,这部分终端能够接收到基站的配置信令,而且根据基站的配置进行侧行通信。而位于网络覆盖范围外的终端,无法接收基站的配置信令,在这种情况下,网络覆盖范围外的终端将根据预配置(pre-configuration)信息及位于网络覆盖范围内的终端发送的物理侧行广播信道(Physical Sidelink Broadcast Channel,PSBCH)中携带的信息确定侧行配置,进行侧行通信。
图5:对于网络覆盖外侧行通信,所有进行侧行通信的终端均位于网络覆盖范围外,所有终端均根据预配置(pre-configuration)信息确定侧行配置进行侧行通信。
需要说明的是,设备到设备通信是基于终端到终端(Device to Device,D2D)的一种侧行链路(Sidelink,SL)传输技术,与传统的蜂窝***中通信数据通过基站接收或者发送的方式不同,因此具有更高的频谱效率以及更低的传输时延。车联网***采用终端到终端直接通信的方式,在3GPP定义了两种传输模式,分别记为:第一模式和第二模式。本申请实施例可以应用于第二模式。
第一模式: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。如图3所示,终端位于网络覆盖范围内,网络为终端分配侧行传输使用的传输资源。
第二模式:终端在资源池中选取一个资源进行数据的传输。如图5所示,终端位于小区覆盖范围外,终端在预配置的资源池中自主选取传输资源进行侧行传输;或者,如图3所示,终端在网络配置的资源池中自主选取传输资源进行侧行传输。
需要说明的是,在NR-V2X中,用户可能处在一个混合的模式下,即既可以使用第一模式进行资源的获取,又同时可以使用第二模式进行资源的获取。
在NR-V2X中,支持自动驾驶,因此对车辆之间数据交互提出了更高的要求,如更高的吞吐量、更低的时延、更高的可靠性、更大的覆盖范围、更灵活的资源分配等。
在LTE-V2X中,支持广播传输方式,在NR-V2X中,引入了单播和组播的传输方式。对于单播传输,其接收端终端只有一个终端,如图6所示,UE1、UE2之间进行单播传输;对于组播传输,其接收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,如图7所示,UE1、UE2、UE3和UE4构成一个通信组,其中UE1发送数据,该组内的其他终端设备都是接收端终端;对于广播传输方式,其接收端是发送端终端周围的任意一个终端,如图8所示,UE1是发送端终端,其周围的其他终端,UE2-UE6都是接收端终端。
为便于更好的理解本申请实施例,对本申请相关的关于NR Uu接口的DRX机制进行说明。
在无线网络中,当有数据需要进行传输时,用户终端(User Equipment,UE)需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***中引入非连续接收(Discontinuous Reception,DRX)机制节能策略。
参见图9,无线资源控制连接(Radio Resource Control Connected,RRC_CONNECTED)状态的UE配置一个DRX周期(DRX cycle)。DRX cycle由“On Duration(持续状态)”和“Opportunity for DRX(DRX机会)”组成。在“On Duration”时间内,UE监听并接收PDCCH,On Duration可以称为激活期(Active Duration或ActiveTime)。在“Opportunity for DRX”时间内,UE不接收PDCCH以减少功耗,Opportunity for DRX可以称为休眠期或非激活期(Inactive Duration或InactiveTime)。相对于DRX on duration,Opportunity for DRX时间又可以称为DRX off duration(不接收状态)。
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On Duration和Off Duration。
为便于更好的理解本申请实施例,对本申请相关的关于SL的DRX机制进行说明。
在终端的节能降耗机制中,为了达到节能目的,考虑在SL引入DRX机制,即SL DRX。类似于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。终端在On Duration范围的时长由DRX配置参数drx_onDurationTimer确定。
在侧行传输***中引入了资源池,所谓资源池即传输资源的集合,无论是网络配置的传输资源还是终端自主选取的传输资源,都是资源池中的资源。可以通过预配置或网络配置的方式配置资源池,可以配置一个或多个资源池。资源池又分为发送资源池和接收资源池。发送资源池即该资源池中的传输资源用于发送侧行数据;接收资源池即终端在该资源池中的传输资源上接收侧行数据。
为便于更好的理解本申请实施例,对本申请相关的基于侦听的资源选取方法进行说明。
在LTE-V2X中,支持完全侦听或部分侦听,其中,完全侦听即终端可以侦听除了发 送数据的时隙之外所有的时隙(或子帧)中其他终端发送的数据;而部分侦听(partial sensing)是为了终端节能,终端只需要侦听部分时隙(或子帧),并且基于部分侦听的结果进行资源选取。
具体的,当高层没有配置部分侦听时,即默认采用完全侦听的方式进行资源选取。
当在时刻n有新的数据包到达,需要进行资源选取,终端会根据过去1秒中的侦听结果,在[n+T
1,n+T
2]ms内进行资源选取,其中T
1<=4;T
2min(prio
TX)≤T
2≤100,T
2min(prio
TX)为高层配置的参数,并且T
1的选取应该大于终端的处理时延,T
2的选取需要在业务的时延要求范围内,例如,如果业务的时延要求是50ms,则20≤T
2≤50,业务的时延要求是100ms,则20≤T
2≤100,如图10所示。
终端在选择窗内进行资源选取的过程如下:(具体的资源选取过程可以参照上面标准中描述的操作步骤,此处列出了几个主要的资源选取步骤)
终端将选择窗内所有可用的资源作为一个集合A,终端对集合A中的资源进行排除操作:
1,如果终端在侦听窗内某些子帧没有侦听结果,则这些子帧在选择窗内对应的子帧上的资源被排除掉。
2,如果终端侦听窗内检测到物理侧行控制信道(Physical Sidelink Control Channel,PSCCH),测量该PSCCH调度的物理侧行共享信道(Physical Sidelink Shared Channel,PSSCH)的参考信号接收功率(Reference Signal Received Power,RSRP),如果测量的PSSCH-RSRP高于PSSCH-RSRP门限,并且根据该控制信息中预留信息确定的其预留的传输资源与本用户待发送的数据存在资源冲突,则用户在集合A中排除掉该资源。其中,PSSCH-RSRP门限的选取是由检测到的PSCCH中携带的优先级信息和终端待传输数据的优先级确定的。
3,如果集合A中剩余的资源个数小于总资源个数20%,终端会提升PSSCH-RSRP的门限3dB,并且重复步骤1-2,直到集合A中剩余的资源个数大于总资源数的20%。
4,终端对集合A中剩余的资源进行侧行接收信号强度指示(Sidelink Received Signal Strength Indicator,S-RSSI)检测,并且按照能量高低进行排序,把能量最低的20%(相对于集合A中的资源个数)资源放入集合B。
5,终端从集合B中等概率的选取一个资源进行数据传输。
相对于完全侦听的方式,基于部分侦听的终端在资源选择窗内选取Y个时隙,并且根据侦听结果判断Y个时隙上的资源是否可以作为候选资源,如果可以就放到集合S
B中,如果集合S
B中的元素个数大于等于Y个时隙上总资源数的20%,将S
B上报给高层。
在LTE-V2X中,在基于部分侦听的资源选取过程中,P
step=100ms。
在LTE-V2X中,完全侦听或部分侦听支持周期性业务,并且支持的业务周期包括{20,50,100,200,300,400,500,600,700,800,900,1000}ms,因此在基于完全侦听或部分侦听的资源选取过程中,P
step=100ms。在NR-V2X中,完全侦听或部分侦听支持周期性业务和非周期性业务,并且周期性业务的周期包括如下:{1:99,100,200,300,400,500,600,700,800,900,1000}ms,其中1:99表示1至99中的所有整数值。此种情况下,一些终端支持的周期值(如1:99)小于P
step=100ms,也即,P
step=100ms无法满足NR-V2X对资源选取过程中的侦听需求,不再适合侦听过程。
基于上述问题,本申请提出了一种侦听方案,能够满足NR-V2X对资源选取过程中的侦听需求。
以下通过具体实施例详述本申请的技术方案。
图11是根据本申请实施例的侦听方法200的示意性流程图,如图11所示,该方法200可以包括如下内容中的至少部分内容:
S210,终端设备获取配置信息,该配置信息包括目标资源池允许的进行周期性预留 的周期值集合和/或该终端设备侦听的周期值;
S220,该终端设备根据该配置信息进行侦听。
在本申请实施例中,终端设备可以根据目标资源池允许的进行周期性预留的周期值集合和/或终端设备侦听的周期值进行侦听,从而,在资源选取过程中,终端设备选取的用于侦听的周期值均为终端设备支持的周期值,满足NR-V2X对资源选取过程中的侦听需求。其中,目标资源池允许的进行周期性预留的周期值又可称为资源预留周期(Resource Reservation Period)。
可选地,本申请实施例可以应用于部分侦听。
在本申请实施例中,该终端设备可以从资源池配置信息中获取该配置信息,该终端设备也可以从网络设备获取该配置信息。
NR-V2X支持的周期性预留的周期值包括:{1:99,100,200,300,400,500,600,700,800,900,1000}ms,其中1:99表示1至99中的所有整数值。但是在一个资源池中,可以在资源池配置信息中指示当前资源池允许的周期性预留的周期值的集合,且该集合最多包括16个元素,如果该集合中的元素取值为0,表示当前资源池支持非周期业务传输,即不进行周期性预留。
可选地,该目标资源池允许的周期值集合包括以下周期值中的至少一种,且该目标资源池允许的周期值集合包括以下周期值中的至多16种:
0ms,1ms,2ms,…,99ms,100ms,200ms,300ms,400ms,500ms,600ms,700ms,800ms,900ms,1000ms。
需要说明的是,1ms,2ms,…,99ms等同于上述1:99表示的毫秒数。
可选地,在该目标资源池允许的周期值集合中包括0ms的情况下,该目标资源池支持非周期业务传输。
可选地,该配置信息可以包括侧行资源预留周期(SL-ResourceReservePediod),该SL-ResourceReservePediod用于指示目标资源池允许的进行周期性预留的周期值集合。
在本申请实施例中,终端设备侦听的周期值用于指示该终端设备需要按照哪些周期值进行侦听。例如,终端设备侦听的周期值为100ms或200ms,终端设备如果要确定在时隙y上的资源是否可用,则终端设备需要对y-100ms对应的时隙,以及y-200ms对应的时隙进行侦听。
可选地,在本申请实施例中,不同的节能等级对应的终端设备侦听的周期值不同;或者,
不同的优先级对应的终端设备侦听的周期值不同。
也就是说,终端设备侦听的周期值与节能等级有关,为不同的节能等级配置该节能等级的终端需要进行侦听的周期值。或者,终端设备侦听的周期值与优先级有关,为不同优先级的终端配置需要进行侦听的周期值。
可选地,该优先级可以是根据侧行控制信息(Sidelink Control Information,SCI)中携带的优先级信息确定的。
可选地,在本申请实施例中,该终端设备可以根据侦听结果选取传输资源。
可选地,S220具体可以是以下实施例中的一个:
实施例1:
其中,
P
s表示所述目标资源池允许的所述周期值集合中的任意一个非零周期值,或者,P
s 表示所述终端设备侦听的周期值。
可选地,该终端设备根据该目标资源池中的最小候选时隙数量,在该选择窗内选取该至少Y个时隙。
可选地,该终端设备可以根据待传输数据的优先级和/或信道繁忙率(Channel Busy Ratio,CBR)确定该最小候选时隙数量。
可选地,该终端设备也可以根据其节能等级确定所述最小候选时隙数量,其中,该节能等级是根据所述终端设备的能力和/或该终端设备的剩余电量确定的。
可选地,该最小候选时隙数量也可以是该配置信息中的参数,即,该配置信息还可以包括该最小候选时隙数量。
在一些实施例中,针对目标资源池中的侧行资源预留周期分别配置其对应的最小候选时隙数量。
例如,资源池允许的资源预留周期分别为100ms、200ms和300ms,资源池配置信息中包括配置信息,用于配置该三个资源预留周期对应的最小候选时隙数量分别为10,20和30。
在一些实施例中,该终端设备根据待传输数据的周期信息确定最小候选时隙数量。
需要说明的是,该最小候选时隙数量也可以称之为最小候选子帧数量(minNumCandidateSF),本申请对此不作限定。
例如,如图12所示,终端设备在时刻n触发进行资源选取或资源重选,确定的选择窗的位置为[n+T
1,n+T
2],终端设备根据配置信息确定在该选择窗内至少选取Y=10个时隙,终端设备选取时隙[n+10,n+19]范围内的10个时隙。对于该10个时隙中的任何一个时隙,该终端设备在侦听窗内侦听时隙

s表示P
s在该目标资源池中对应的逻辑时隙的数量;
P
s表示该目标资源池允许的该周期值集合中的任意一个非零周期值,或者,P
s表示该终端设备侦听的周期值。
其中,N表示20ms内可用于侧行传输的时隙数量。可选的,N根据网络配置参数时分双工(Time Division Duplex,TDD)上下行公共配置(TDD-UL-DL-ConfigCommon)确定,该参数用于指示***的时隙配置。如果一个时隙中从时域符号S开始的连续的L个符号都是上行符号,则该时隙可用于侧行传输。N表示在20ms的时间内可用于侧行传输的时隙数量。其中,S根据参数侧行开始符号(SL-StartSymbol)确定,L根据参数侧行符号长度(SL-LengthSymbols)确定。可选的,对于专有载波或专有频谱,所有的时隙都可用于侧行传输,此时参数N的值即为20ms的时间对应的时隙数量。
实施例3:
该终端设备在选择窗内选取至少Y个时隙,Y为正整数;
其中,
P′

其中,
T
s表示该选择窗的结束位置对应的毫秒数;

s表示P
s在该目标资源池中对应的逻辑时隙的数量;
P
s表示该目标资源池允许的该周期值集合中的任意一个非零周期值,或者,P
s表示该终端设备侦听的周期值;
例如,终端设备在时隙n进行资源选取,确定的选择窗为[n+4,n+100],其中4、100表示时隙n之后的第4个和第100个时隙,如果子载波间隔为30kHz,则选择窗对应的结束位置,即n+100,为时隙n后的50ms,即T
s=50;对于资源池允许的周期10ms,即P
s=10,如果考虑专用载波,即所有的时隙都可用于侧行传输,此时P′
s=10,Q=5,如果终端设备选取了选择窗内的时隙n+10,则该时隙n+10之前的周期性传输所在的时隙分别为时隙n,时隙n-10、时隙n-20、时隙n-30和时隙n-40;终端设备确定的侦听窗为[n-100,n-1],则终端设备在该侦听窗内需要侦听的时隙为时隙n-10,即该侦听窗内针对时隙n+10的最后一次周期性传输的时隙。
实施例5:
该终端设备在选择窗内选取至少Y个时隙,Y为正整数;
其中,
P′
s表示P

s表示P
s在该目标资源池中对应的逻辑时隙的数量;
P
s表示该目标资源池允许的该周期值集合中的任意一个非零周期值,或者,P
s表示该终端设备侦听的周期值。
也就是说,终端设备在其发送资源池内进行侦听。例如,终端设备在选择窗内的目标资源池(终端设备的发送资源池)中选取时隙
根据该目标资源池允许的业务周期值确定在侦听窗内的侦听时隙
若该时隙
不属于该目标资源池,则侦听位于该时隙
之后的第一个属于该目标资源池的时隙,或者,侦听位于该时隙
之前的第一个属于该目标资源池的时隙。
需要说明的是,实施例5中的方式可以适用于上述实施例1至实施例4中,即在实施例1中,若
不属于该目标资源池的情况下,该终端设备侦听该时隙
之后的第一个属于该目标资源池的时隙,或者,该终端设备侦听该时隙
之前的第一个属于该目标资源池的时隙;在实施例2或实施例3中,若
不属于该目标资源池的情况下,该终端设备侦听该时隙
之后的第一个属于该目标资源池的时隙,或者,该终端设备侦听该时隙
之前的第一个属于该目标资源池的时隙;在实施例4中,若
不属于该目标资源池的情况下,该终端设备侦听该时隙
