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。
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。
请参考图1,其示出了本申请一个实施例提供的网络架构的示意图。该网络架构可以包括:核心网11、接入网12和终端设备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,5G(5th Generation,第五代移动通信技术)NR(New Radio,新空口)系统的核心网中可以包括AMF(Access and Mobility Management Function,接入和移动性管理功能)实体、UPF(User Plane Function,用户平面功能)实体和SMF(Session Management Function,会话管理功能)实体等设备。
接入网12中包括若干接入网设备14。5G NR系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network,新一代无线接入网)。接入网设备14是一种部署在接入网12中用以为终端设备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系统中,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系统中,称为gNodeB或者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,上述为终端设备13提供无线通信功能的装置统称为接入网设备。
终端设备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设备13。终端设备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设备。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系统中的NG接口。接入网设备14与终端设备13之间通过某种空中技术互相通信,例如Uu接口。
终端设备13和终端设备13(例如车载设备与其它设备(如其它车载设备、手机、RSU(Road Side Unit,路测单元)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传输即为终端设备与终端设备之间通过侧行链路直接进行通信数据传输,不同于传统的蜂窝系统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设备(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(vehicle to everything,车联网)场景下的车对车通信为示例,SL技术可以应用于各种终端设备之间直接进行通信的场景。或者说,本申请中的终端设备是指任意一种利用SL技术通信的设备。
本公开实施例中的“5G NR系统”也可以称为5G系统或者NR系统,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系统,也可以适用于5G NR系统后续的演进系统。
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:终端设备的传输资源是由接入网设备(如基站)分配的,终端设备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设备分配单次传输的传输资源,也可以为终端设备分配半静态传输的传输资源。
模式B:终端设备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,终端设备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。
接下来主要介绍NR V2X系统中SL通信,终端设备自主进行资源选择的方法(也即上述模式B)。
NR V2X系统中SL通信的物理层结构如图2所示。PSCCH(Physical Sidelink Control Channel,物理侧行控制信道)用于承载第一侧行控制信息,PSSCH(Physical Sidelink Shared Channel,物理侧行共享信道)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,方便其他终端设备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,方便其他终端设备解调该PSSCH中的数据。
在NR V2X系统中,上述模式B下,终端设备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。
资源预留是指终端设备在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系统中,支持TB(Transport Block,传输块)内的资源预留也支持TB间的资源预留。
如图3所示,终端设备发送第一侧行控制信息,利用其中“Time resource assignment(时间资源分配)”和“Frequency resource assignment(频率资源分配)”域指示当前TB的N个时频资源(包括当前发送所用的资源)。其中N≤Nmax,在NR V2X中,Nmax等于2或3。同时,上述N个被指示的时频资源应分布在W个时隙内。在NR V2X中,W等于32。例如,图3所示的TB1中,终端设备在PSSCH发送初传数据的同时在PSCCH中发送第一侧行控制信息,利用上述两个域指示初传和重传1的时频资源位置(即此时N=2),即预留重传1的时频资源。并且,初传和重传1在时域上分布在32个时隙内。同理,在图3所示的TB1中,终端设备利用重传1的PSCCH中发送的第一侧行控制信息指示重传1和重传2的时频资源位置,重传1与重传2在时域上分布在32个时隙内。
同时,终端设备发送第一侧行控制信息时利用“Resource reservation period(资源预留周期)”域进行TB间的资源预留。例如图3中,终端设备在发送TB1的初传的第一侧行控制信 息时,利用“Time resource assignment”和“Frequency resource assignment”域指示TB1初传和重传1的时频资源位置,记为{(t 1,f 1),(t 2,f 2)}。其中t 1、t 2代表TB1初传和重传1资源的时域位置,f 1、f 2代表相应的频域位置。如果该第一侧行控制信息中,“Resource reservation period”域的取值为100毫秒,则该SCI(Sidelink Control Information,侧行链路控制信息)同时指示了时频资源{(t1+100,f1),(t2+100,f2)},这两个资源用于TB2初传和重传1的传输。同理,在TB1重传1中发送的第一侧行控制信息,也利用“Resource reservation period”域预留了TB2重传1和重传2的时频资源。在NR V2X中,“Resource reservation period”域可能的取值为0、1-99、100、200、300、400、500、600、700、800、900、1000毫秒,相比较LTE(Long Term Evaluation,长期演进)V2X更为灵活。但在每个资源池中,只配置了其中的e种取值,终端设备根据所用的资源池确定可能使用的值。记资源池配置中的e种取值为资源预留周期集合M,示例性地,e小于等于16。
此外,通过网络配置或预配置,上述TB间的预留可以以资源池为单位激活或去激活。当激活TB间的预留时,第一侧行控制信息中包括“Resource reservation period”域。当去激活TB间的预留时,第一侧行控制信息中不包括“Resource reservation period”域。在激活TB间的预留时,一般情况下,在触发资源重选之前,终端设备所用的“Resource reservation period”域的取值,即资源预留周期都不会变,终端设备每发送一次第一侧行控制信息,都利用其中的“Resource reservation period”域预留下个周期的资源,用于另一个TB的传输,从而达到周期性地半持续传输。
当终端设备工作在上述模式B下,终端设备可以通过侦听其他终端设备发送的PSCCH,获取其他终端设备发送的第一侧行控制信息,从而得知其他终端设备所预留的资源。终端设备在进行资源选择时,会排除其他终端设备预留的资源,从而避免资源碰撞。
在NR V2X系统中,上述模式B下,终端设备需要自行选择资源。
如图4所示,终端设备在时隙n触发资源选择或重选或时隙n是高层触发物理层上报候选资源集合的时隙,资源选择窗从n+T 1开始,到n+T 2结束。0<=T 1<=T proc,1,当子载波间隔是15,30,60,120kHz时,T proc,1为3,5,9,17个时隙。T 2min<=T 2<=业务的剩余时延预算,T 2min的取值集合为{1,5,10,20}*2 μ个时隙,其中μ=0,1,2,3对应于子载波间隔是15,30,60,120kHz的情况,终端设备根据自身待发送数据的优先级从该取值集合中确定T 2min。例如当子载波间隔是15kHz时,终端设备根据自身待发送数据的优先级从集合{1,5,10,20}中确定T 2min。当T 2min大于等于业务的剩余时延预算时,T 2等于业务的剩余时延预算。剩余时延预算即数据的时延要求的对应时刻与当前时刻的差值。例如时隙n到达的数据包,时延要求为50毫秒,假设一个时隙为1毫秒,如果当前时刻为时隙n,则剩余时延预算为50毫秒,若当前时刻为时隙n+20,则剩余时延预算为30毫秒。
终端设备在n-T 0到n-T proc,0进行资源侦听(不包括n-T proc,0),T 0的取值为100或1100毫秒。当子载波间隔是15,30,60,120kHz时,T proc,0为1,1,2,4个时隙。实际上,终端设备在每个时隙(除了自己的发送时隙)都会侦听其他终端设备发送的第一侧行控制信息,当时隙n触发资源选择或重选后,终端设备使用n-T 0到n-T proc,0资源侦听的结果。
Step 1:终端设备将资源选择窗内所有属于终端设备所用资源池的可用资源作为资源集合A,集合A中的任意一个资源记为R(x,y),x和y分别指示资源的频域位置和时域位置。记集合A中资源的初始数量为M total。终端设备根据资源侦听窗内的未侦听时隙(Step 1-1)和/或资源侦听窗内的资源侦听结果(Step 1-2)对资源集合A中的资源进行排除。终端设备判断资源R(x,y)或与资源R(x,y)对应的一系列周期性资源是否与Step 1-1中根据未侦听时隙确定的时隙或Step 1-2中根据侦听到的第一侧行控制信息确定的资源重叠,若重叠则从资源集合A中排除资源R(x,y)。
Step 1-1:如果终端设备在侦听窗内时隙m发送数据,没有进行侦听,则终端设备将根据时隙m和终端设备所用资源池中每一种允许的资源预留周期,以该资源预留周期为间隔,确 定对应的Q个时隙。若该Q个时隙与资源R(x,y)或与资源R(x,y)对应的一系列周期性资源重叠,则从资源集合A中排除资源R(x,y)。上述Q=1或者
Figure PCTCN2021092742-appb-000001
(代表向上取整)。T scal等于T 2转化为毫秒后的值。P rx为终端设备所用资源池允许的资源预留周期的一种。
例如图4中的子图(a),终端设备在时隙m没有进行侦听,依次根据所用资源池配置中的资源预留周期集合M中每一种资源预留周期进行资源排除,对于其中某个资源预留周期1,假定Q值计算为2,则对应的Q个时隙为图4子图(a)中从时隙m映射的以资源预留周期1为间隔接下来的2个以横线阴影标识的时隙。对于其中某个资源预留周期2,假定Q值计算Q=1,则对应的Q个时隙为图4子图(a)中从时隙m映射的以资源预留周期2为间隔的接下来的1个点状阴影标识的时隙。
终端设备将判断每一种预留周期对应的Q个时隙,是否与资源R(x,y)或与资源R(x,y)对应的一系列周期性资源重叠,若重叠则从资源集合A中排除资源R(x,y)。
可选地,当终端设备所用资源池去激活TB间的预留时,终端设备可以不执行上述Step1-1。
Step 1-2:如果终端设备在资源侦听窗的时隙m内侦听到PSCCH中传输的第一侧行控制信息,测量该PSCCH的SL-RSRP(Sidelink Reference Signal Received Power,侧行参考信号接收功率)或者该PSCCH调度的PSSCH的SL-RSRP(即与该PSCCH在同一时隙中发送的PSSCH的SL-RSRP)。
如果测量的SL-RSRP大于SL-RSRP阈值,且终端设备所用资源池激活TB间的资源预留,则终端设备将根据时隙m和侦听到的第一侧行控制信息中携带的资源预留周期,以该资源预留周期为间隔,确定对应的Q个时隙。终端设备假定在该Q个时隙中也收到了相同内容的第一侧行控制信息。终端设备将判断在时隙m收到的第一侧行控制信息和这些假定收到的Q个第一侧行控制信息的“Time resource assignment”和“Frequency resource assignment”域指示的资源与资源R(x,y)或与资源R(x,y)对应的一系列周期性资源是否重叠,若重叠则从集合A中排除对应资源R(x,y)。上述Q=1或者
Figure PCTCN2021092742-appb-000002
(代表向上取整)。T scal等于T 2转化为毫秒后的值。P rx为侦听到的第一侧行控制信息中携带的资源预留周期。
例如图4中的子图(b),当终端设备所用资源池激活TB间的预留,如果终端设备在时隙m资源E(v,m)上侦听到PSCCH中的第一侧行控制信息,该第一侧行控制信息中的资源预留周期为P rx,假定Q值计算为1,终端设备将假定在时隙m+P rx上也收到了相同内容的第一侧行控制信息。终端设备将判断在时隙m收到的第一侧行控制信息和假定在时隙m+P rx收到的第一侧行控制信息的“Time resource assignment”和“Frequency resource assignment”域指示的资源1、2、3、4、5、6与资源R(x,y)或与资源R(x,y)对应的一系列周期性资源是否重叠,若重叠且满足RSRP条件则从资源集合A中排除资源R(x,y)。
如果终端设备测量的SL-RSRP大于SL-RSRP阈值,且终端设备所用资源池去激活TB间的资源预留,则终端设备只判断在时隙m收到的第一侧行控制信息的“Time resource assignment”与“Frequency resource assignment”域指示的资源是否与资源R(x,y)或与资源R(x,y)对应的一系列资源重叠,若重叠则从资源集合A中排除资源R(x,y)。
例如图4中的子图(b),当终端设备所用资源池去激活TB间的预留,如果终端设备在时隙m资源E(v,m)上侦听到PSCCH中的第一侧行控制信息,则终端设备判断该第一侧行控制信息中“Time resource assignment”和“Frequency resource assignment”域指示的资源1、2、3与资源R(x,y)或与资源R(x,y)对应的一系列周期性资源是否重叠,若重叠且满足RSRP条件则从资源集合A中排除资源R(x,y)。
如果在上述资源排除后资源集合A中剩余资源不足M total*X,则将SL-RSRP阈值抬升3dB,重新执行Step 1。物理层将资源排除后的资源集合A作为候选资源集合上报给高层。
Step 2:高层从上报的候选资源集合中随机选择资源发送数据。即终端设备从候选资源集合中随机选择资源发送数据。
需要注意的是:
1.上述RSRP阈值是由终端设备侦听到的PSCCH中携带的优先级P1和终端设备待发送数据的优先级P2决定的。终端设备所用资源池的配置中包含一张SL-RSRP阈值表,该SL-RSRP阈值表包含了所有优先级组合对应的SL-RSRP阈值。资源池的配置可以是网络配置或者预配置的。
例如,如表1所示,假设P1与P2的优先级等级可选值均为0-7,则不同优先级组合对应的SL-RSRP阈值用γ ij表示,其中,γ ij中的i为优先级等级P1的取值,j为优先级等级P2的取值。
表1 SL-RSRP阈值表
Figure PCTCN2021092742-appb-000003
当终端设备侦听到其他终端设备发送的PSCCH,获取该PSCCH中传输的第一侧行控制信息中携带的优先级P1以及待发送数据的优先级P2,终端设备通过查表1的方式确定SL-RSRP阈值。
2.终端设备利用测量到的PSCCH-RSRP还是该PSCCH调度的PSSCH-RSRP与SL-RSRP阈值进行比较,取决于终端设备所用资源池的资源池配置。资源池的配置可以是网络配置或者预配置的。
3.上述X,X可能的取值为{20%,35%,50%}。终端设备所用资源池的配置中包含优先级与上述可能取值的对应关系,终端设备根据待发送数据的优先级及该对应关系,确定X的值。资源池配置可以是由网络配置或者预配置。
上述介绍为NR-V2X中的一种SL通信方式,即终端设备通过资源侦听自主选取传输资源,自行在侧行链路上进行数据传输。该SL通信的方式也可应用在手持终端与手持终端间的直接通信,行人与车辆间的直接通信等各种SL通信中。
在Release 17版本的标准化中,对于上述终端设备通过侦听进行自主资源选取的SL通信方式进一步实施优化,提出了终端设备间协作进行资源选取的SL通信方式。
例如图5所示,UE 1是进行自主资源选取的终端设备,在UE 1进行资源选取时还可以考虑来自UE 2的辅助信息,从而进一步避免选择的资源与其他UE发生资源碰撞,提升通信可靠性。
这种UE间协作的触发机制主要有两种:
(1)由UE 1发起,发送触发信息给UE 2,UE 2接收触发信息,并确定辅助信息发送给UE 1。
(2)由UE 2发起,在满足特定条件时,UE 2确定并发送辅助信息给UE 1。上述特定条件,比如侦听到UE 1发送的资源与其他UE冲突,或者周期性确定并向UE 1发送辅助信息。
上述辅助信息,至少包括UE 2确定的资源集合。例如,上述资源集合中的资源为适合UE 1传输的资源或者上述资源集合中的资源为不适合UE 1传输的资源。例如,UE 2根据侦听到的第一侧行控制信息,即根据自身资源侦听结果,确定上述资源集合。
上述承载辅助信息可以通过第一侧行控制信息、第二侧行控制信息、PSSCH、MAC(Media  Access Control,媒体接入控制)CE(Control Element,控制单元)、PC5-RRC(Radio Resource Control,无线资源控制)、PSFCH(Physical Sidelink Feedback Channel,物理侧行链路反馈信道)中的一种或多种。
UE 1接收到辅助信息后,利用辅助信息进行资源选取或资源排除。例如,辅助信息包含的资源集合中的资源为适合UE 1传输的资源,则UE 1在自身确定的候选资源集合和该资源集合的交集中选取传输资源。
请参考图6,其示出了本申请一个实施例提供的确定资源选择窗和侦听窗的方法的流程图,该方法可以包括如下步骤:

又例如,第二时间包括第二终端接收辅助信息的处理时间以及接收第一侧行控制信息的处理时间。
可选地,上述第一侧行控制信息用于确定第二终端的候选资源集合,本申请中将第二终端的候选资源集合称作“第二候选资源集合”。第二终端可以确定资源选择窗和资源侦听窗,然后根据在资源侦听窗中接收到的第一侧行控制信息和/或资源侦听窗中的未侦听时隙,对资源选择窗中的资源进行排除,得到第二候选资源集合。

对于T 32,如果T 2min小于剩余时延预算-p-q,则T 32大于或等于T 2min,和/或,T 32小于或等于剩余时延预算-p-q。如果T 2min大于或等于剩余时延预算-p-q,则T 32等于剩余时延预算-p-q。T 32在上述范围内的取值取决于第一终端的实现,本申请对此不作限定。T 32的单位为时隙或毫秒或符号。T 2min为大于0的数值,有关T 2min的介绍说明可参见上文内容,此处不再赘述。
在一些其他实施例中,T 32等于w 1,w 1是标准规定的预设值,或由网络配置,或预配置,或由第二终端指示给第一终端,或根据第一终端发送辅助信息所用资源的时域长度和/或频域宽度确定,或取决于第一终端的实现。或者,T 32等于T 31+w 2,w 2是标准规定的预设值,或由网络配置,或预配置,或由第二终端指示给第一终端,或根据第一终端发送辅助信息所用资源的时域长度和/或频域宽度确定,或取决于第一终端的实现。

在示例性实施例中,第一终端发送辅助信息的时刻小于或等于目标时频资源对应的时刻-p-T proc,1,目标时频资源为第二终端指示给第一终端的时频资源。可选地,当第二终端指示给第一终端一个时频资源时,目标时频资源记为这一个时频资源;当第二终端指示给第一终端多个时频资源时,目标时频资源可以是该多个时频资源中时域上第一个时频资源(即时域上最靠前的时频资源),或者是该多个时频资源中时域上最后一个时频资源(即时域上最靠后的时频资源),或者是该多个时频资源中的任意一个时频资源。其中,T proc,1为大于0的数值,有关T proc,1的介绍说明可参见上文内容,此处不再赘述。示例性地,在第二终端决定是否利用该目标时频资源进行传输之前,第一终端先确定出辅助信息并发送给第二终端,并给第二终端预留接收该辅助信息的处理时间,以使得第二终端能够参考该辅助信息,更加准确地决策出是否利用该目标时频资源进行传输。
在示例性实施例中,第一终端确定出上述资源选择窗和资源侦听窗之后,根据该资源侦听窗中的侦听结果和/或未侦听时隙,对资源选择窗中的资源进行排除,得到第一候选资源集合。示例性地,第一终端执行上文介绍的Step 1(包括Step 1-1和/或Step 1-2),对资源选择窗中的资源进行排除,得到第一候选资源集合。
在一个示例中,辅助信息中包含的资源集合为第一候选资源集合。如图7所示,假设第一终端得到的第一候选资源集合包括资源x、y、z和v,第一终端将该第一候选资源集合作为辅助信息中的资源集合,并将该辅助信息发送给第二终端。在另一个示例中,辅助信息中包含的资源集合为排除的资源集合,例如,第一终端将Step 1中排除的资源集合作为辅助信息中的资源集合,并将该辅助信息发送给第二终端。
可选地,在辅助信息中包含的资源集合为第一候选资源集合的情况下,第二终端确定第二候选资源集合,在第二候选资源集合和辅助信息中包含的资源集合的交集中选择传输资源。或者,在辅助信息中包含的资源集合为排除的资源集合的情况下,第二终端确定第二候选资源集合,在第二候选资源集合和辅助信息中包含的资源集合的差集中选择传输资源。
综上所述,本申请实施例提供的技术方案,对于终端设备间协作的资源选择模式,第一终端在确定资源选择窗和/或资源侦听窗时,考虑了终端处理时间(如第一终端准备发送辅助信息的处理时间、第一终端到第二终端的传播时延、第二终端接收辅助信息的处理时间等),能够使得基于上述资源选择窗和资源侦听窗确定的辅助信息中的资源集合更加准确,更符合第二终端的时序,保证辅助信息中资源集合的有效性。
