图1至图4是本申请实施例提供的车载终端到车载终端的系统框架。
如图1所示,在网络覆盖内侧行通信中,所有进行侧行通信的终端(包括终端1和终端2)均处于同一网络设备的覆盖范围内,从而,所有终端均可以通过接收网络设备的配置信令,基于相同的侧行配置进行侧行通信。
如图2所示,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网络设备的覆盖范围内,这部分终端(即终端1)能够接收到网络设备的配置信令,而且根据网络设备的配置进行侧行通信。而位于网络覆盖范围外的终端(即终端2),无法接收网络设备的配置信令,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侧行广播信道PSBCH中携带的信息确定侧行配置,进行侧行通信。
如图3所示,对于网络覆盖外侧行通信,所有进行侧行通信的终端(包括终端1和终端2)均位于网络覆盖范围外,所有终端均根据预配置信息确定侧行配置进行侧行通信。
设备到设备通信是基于D2D的一种侧行链路(Sidelink,SL)传输技术,与传统的蜂窝系统中通信数据通过网络设备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。车联网系统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:第一模式和第二模式。
第一模式:
终端的传输资源是由网络设备分配的,终端根据网络设备分配的资源在侧行链路上进行数据的发送;网络设备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1中,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3中,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;或者在图1中,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。
第二模式资源选择按照以下两个步骤进行:
步骤1:
终端将资源选择窗内所有的可用资源作为资源集合A。
如果终端在侦听窗内某些时隙发送数据,没有进行侦听,则这些时隙在选择窗内对应的时隙上的全部资源被排除掉。终端利用所用资源池配置中的“resource reservation period”域的取值集合确定选择窗内对应的时隙。
如果终端在侦听窗内侦听到PSCCH,测量该PSCCH的RSRP或者该PSCCH调度的PSSCH的RSRP,如果测量的RSRP大于SL-RSRP阈值,并且根据该PSCCH中传输的侧行控制信息中的资源预留信息确定其预留的资源在资源选择窗内,则从集合A中排除对应资源。如果资源集合A中剩余资源不足资源集合A进行资源排除前全部资源的X%,则将SL-RSRP阈值抬升3dB,重新执行步骤1。上述X可能的取值为{20,35,50},终端根据待发送数据的优先级从该取值集合中确定参数X。同时,上述SL-RSRP阈值与终端侦听到的PSCCH中携带的优先级以及终端待发送数据的优先级有关。终端将集合A中经资源排除后的剩余资源作为候选资源集合。
步骤2:
终端从候选资源集合中随机选择若干资源,作为其初次传输以及重传的发送资源。
在NR-V2X中,需要支持自动驾驶,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。图4是本申请实施例提供的单播传输的示意图。如图4所示,终端1、终端2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。图5是本申请实施例提供的组播传输的示意图。如图5所示,终端1、终端2、终端3和终端4构成一个通信组,其中终端1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。图5是本申请实施例提供的广播传输的示意图。如图6所示,终端1是发送端终端,其周围的其他终端,第终端2-终端6都是接收端终端。
下面结合图7和图8对NR-V2X中的时隙结构进行说明。
图7是本申请实施例提供的不包括PSFCH信道的时隙结构的示例;图8是本申请实施例提供的包括PSFCH信道的时隙结构的示例。
如图7或图8所示,NR-V2X中PSCCH在时域上从该时隙的第二个侧行符号开始,占用2个或3个OFDM符号,在频域上可以占用{10,12 15,20,25}个PRB。为了避免UE对PSCCH的盲检测,在一个资源池内只允许配置一个PSCCH符号个数和PRB个数。另外,因为子信道为NR-V2X中PSSCH资源分配的最小粒度,PSCCH占用的PRB个数必须小于或等于资源池内一个子信道中包含的PRB个数,以免对PSSCH资源选择或分配造成额外的限制。PSSCH在时域上也是从该时隙的第二个侧行符号开始,该时隙中的最后一个时域符号为保护间隔GP符号,其余符号映射PSSCH。该时隙中的第一个侧行符号是第二个侧行符号的重复,通常接收端终端将第一个侧行符号用作AGC(自动增益控制,Automatic Gain Control)符号,该符号上的数据通常不用于数据解调。PSSCH在频域上占据K个子信道,每个子信道包括N个连续的PRB。
如图7所示,时隙中可以不包括PSFCH信道。
如图8所示,当时隙中包含PSFCH信道时,该时隙中倒数第二个和倒数第三个符号用作PSFCH信道传输,在PSFCH信道之前的一个时域符号用作GP符号。
在NR-V2X中引入2阶SCI,第一阶SCI承载在PSCCH中,用于指示PSSCH的传输资源、预留资源信息、MCS等级、优先级等信息,第二阶SCI在PSSCH的资源中发送,利用PSSCH的DMRS进行解调,用于指示源ID、目标ID、HARQ ID、NDI等用于数据解调的信息。第二阶SCI从PSSCH的第一个DMRS符号开始映射,先频域再时域映射。图9是本申请实施例提供的PSCCH和PSSCH帧结构的示意图,如图9所示,PSCCH占据3个符号(符号1、2、3),PSSCH的DMRS占据符号4、11,第二阶SCI从符号4开始映射,在符号4上和DMRS频分复用,第二阶SCI映射到符号4、5、6,第二阶SCI占据的资源大小取决于第二阶SCI的比特数。
在NR-V2X中,为了提高可靠性,引入了侧行反馈信道。
图10是本申请实施例提供的针对单播传输的侧行反馈的示意图。
如图10所示,对于单播传输,发送端终端向接收端终端发送侧行数据(包括PSCCH和PSSCH),接收端终端向发送端终端发送HARQ反馈信息(包括ACK或NACK),发送端终端根据接收端终端的反馈信息判断是否需要进行重传。其中,HARQ反馈信息承载在侧行反馈信道中,例如PSFCH。
在一些实施例中,发送端终端可以通过SCI激活或者去激活侧行反馈,如果侧行反馈被激活,则接收端终端接收发送端终端发送的侧行数据,并且根据检测结果向发送端反馈HARQ ACK或者NACK,发送端终端根据接收端的反馈信息决定发送重传数据或者新数据;如果侧行反馈被去激活,接收端终端不需要发送反馈信息,发送端终端通常采用盲重传的方式发送数据,例如,发送端终端对每个侧行数据重复发送K次,而不是根据接收端终端反馈信息决定是否需要发送重传数据。
在NR-V2X中,引入了物理侧行反馈信道(Physical Sidelink Feedback Channel,PSFCH),该PSFCH只承载1比特的HARQ-ACK信息,在时域上占据2个时域符号(第二个符号承载侧行反馈信息,第一个符号上的数据是第二个符号上数据的复制,但是该符号用作AGC),频域上占据1个PRB。
图11是本申请实施例提供的PSFCH和PSCCH/PSSCH时隙结构的示意图。
如图11所示,一个时隙可包括PSFCH、PSCCH、和PSSCH所占的时域符号。具体的,在一个时隙中,最后一个符号用作GP,倒数第二个符号用于PSFCH传输,倒数第三个符号数据和PSFCH符号的数据相同,用做AGC,倒数第四个符号也用作GP,时隙中的第一个符号用作AGC,该符号上的数据和该时隙中第二个时域符号上的数据相同,PSCCH占据3个时域符号,剩余的符号可用于PSSCH传输。
在一些实施例中,为了降低PSFCH信道的开销,定义在每N个时隙中的一个时隙包括PSFCH传 输资源,即侧行反馈资源的周期是N个时隙,其中N=1、2、4,参数N是预配置或者网络配置的。
图12是本申请实施例提供的每N个时隙中的一个时隙包括PSFCH传输资源的示意图。
如图12所示,假设N=4,则每4个时隙中的一个时隙包括PSFCH传输资源,即侧行反馈资源的周期是4个时隙。其中,时隙2、3、4、5中传输的PSSCH,其反馈信息都是在时隙7中传输的,因此可以把时隙{2、3、4、5}看做一个时隙集合,该时隙集合中传输的PSSCH,其对应的PSFCH是在相同的时隙中。
在一些实施例中,PSFCH资源可根据PSSCH所在的时隙、以及占用的子带的起始位置确定。
图13是本申请实施例提供的PSFCH的传输资源和PSSCH的资源对应关系的示意图。
如图13所示,假设N=4,在不同时隙相同子带起始位置传输的PSSCH,分别对应反馈时隙中的不同的PSFCH资源。例如,左上角传输的PSSCH可对应反馈时隙中的PSFCH资源4。
在一些实施例中,在资源池配置信息中包括PSCCH/PSSCH的传输资源,以及PSFCH的传输资源。作为示例,所述资源池配置信息可实现为如下信息元素(information element):
Figure PCTCN2021105617-appb-000001
发送端终端TX UE在为其配置的发送资源池中发送PSCCH/PSSCH,接收端在为其配置的接收资源池中检测是否存在其他终端发送的PSCCH/PSSCH,如果检测到,接收端终端根据PSCCH/PSSCH的传输资源以及接收资源池中PSFCH的配置信息确定发送PSFCH的传输资源;发送端发送PSCCH/PSSCH后,会根据发送资源池中的PSFCH配置信息确定接收PSFCH的资源,并进行PSFCH的检测。为了让发送端和接收端能够正常进行数据传输,通常为发送端终端配置的发送资源池与为接收端终端配置的接收资源池相同。从而使得发送端和接收端根据PSSCH传输资源以及各自资源池中的PSFCH的配置信息可以确定相同的PSFCH传输资源。
在Rel-15NR Uu口传输系统中,引入了微时隙(mini-slot)传输或调度,即网络调度的PUSCH或PDSCH不是以时隙为粒度,而是以时隙内的时域符号为粒度,从而可以达到降低时延的目的。
图14是本申请实施例提供NR Uu口传输系统中的时隙和微时隙(mini-slot)的对应关系的示意图。
如图14所示,位于时隙头部的PDCCH既可以调度位于同一时隙内的PDSCH(以微时隙1作为资源单位),也可以调度位于时隙尾部的PUSCH(以微时隙2作为资源单位),从而可以在一个时隙内对上下行数据进行快速调度。
在NR系统中,支持以{2,4,7}个时域符号为时域调度粒度的微时隙调度。
在NR SL系统中,侧行传输或调度都是以时隙为粒度的,但是当NR SL应用到工业互联网等对时延要求很高的场景时,对系统的时延具有更高的要求,因此,基于微时隙的侧行传输方式是需要考虑的一种可行的传输方案,但是如何在侧行链路上支持微时隙的传输是需要解决的问题。本申请实施例提供了一种无线通信方法、终端设备和网络设备,能够降低侧行传输的时延,进而能够提升用户体验。

换言之,可通过指示所述PSFCH在一个时隙中占据的起始时域符号的索引(如符号索引#0~符号索引13)配置所述PSFCH在时隙中的起始时域符号地位置。
可选的,所述第五参数也可称为侧行链路PSFCH起始符号参数(sl-PSFCH-StartSymbol)。
示例性地,假设sl-PSFCH-StartSymbol=11,则表示所述PSFCH的起始符号位置为时隙中的符号#11,所述PSFCH占据的时域符号为符号#11和符号#12,如上述情况3/5/6。假设sl-PSFCH-StartSymbol=4,则表示所述PSFCH的起始符号位置为时隙中的符号#4,所述PSFCH占据的时域符号为符号#4和符号#5,如上述情况2/4。假设sl-PSFCH-StartSymbol=6,则表示所述PSFCH的起始符号位置为时隙中的符号#6,所述PSFCH占据的时域符号为符号#6和符号#7,如上述情况7。假设sl-PSFCH-StartSymbol=5,则表示所述PSFCH的起始符号位置为时隙中的符号#5,所述PSFCH占据的时域符号为符号#5和符号#6,如上述情况8。
可选的,所述第五指示信息包括第五比特位图,针对所述第五比特位图中的每一个比特位,若所述比特位的取值为第一数值,则指示所述比特位对应的时域符号为所述PSFCH在一个时隙中占据的起始时域符号,若所述比特位的取值为第二数值,则指示所述比特位对应的时域符号不是所述PSFCH在一个时隙中占据的起始时域符号。例如,所述第一数值可以为1且所述第二数值可以为0。再如,所述第一数值可以为0且所述第二数值可以为1。

可选的,所述第五指示信息包括第六比特位图,针对所述第六比特位图中的每一个比特位,若所述比特位的取值为第一数值,则指示所述比特位对应的时域符号为所述PSFCH在一个时隙中占据的时域符号,若所述比特位的取值为第二数值,则指示所述比特位对应的时域符号不是所述PSFCH在一个时隙中占据的时域符号。例如,所述第一数值可以为1且所述第二数值可以为0。再如,所述第一数值可以为0且所述第二数值可以为1。

以所述第五比特位图为例,假设所述第五比特位图为[0,0,0,0,1,0,0,0,0,0,0,1,0,0],其中,符号#4和符号#11置为1,即表示符号#4和符号#11分别为所述PSFCH的起始时域符号的位置,即该时隙中包括两套PSFCH传输资源,第一套PSFCH传输资源位于符号#4和符号#5,第二套PSFCH传输资源位于符号#11和符号#12,如上述情况2。
需要说明的是,在上述示例中,是假设在微时隙的资源池配置中,对应的PSFCH的结构还是采用NR SL系统中的PSFCH格式0,即一个PSFCH在频域占据1个PRB,时域占据2个时域符号,PSFCH与其关联的PSSCH是TDM方式复用,并且通过序列来承载侧行反馈信息。但是在微时隙的结构下,如果还采用TDM的方式复用PSSCH和PSFCH,会导致系统资源利用率低,因此,可以支持PSFCH和PSSCH采用FDM复用方式,此时,PSFCH占据的时域符号的个数与传输其关联的PSCCH/PSSCH的微时隙占据的时域符号的个数相同,即,如果PSCCH/PSSCH采用微时隙传输,且占据A个时域符号,则该PSCCH/PSSCH对应的PSFCH也占据A个时域符号。例如,资源池配置的微时隙占据7个时域符号,则该资源池中还可以同时配置PSFCH传输资源,并且所述PSFCH传输资源也占据7个时域符号。为描述方便,下面将上述占据2个时域符号的PSFCH格式称为第一PSFCH格式,将上述和微时隙的侧行传输占据相同的时域符号的个数的PSFCH格式称为第二PSFCH格式。

在一种实现方式中,所述第六指示信息携带在所述资源池配置信息中的信息域中;若所述第六指示信息的取值为第四数值,则指示所述资源池支持的PSFCH格式为所述第一PSFCH格式;若所述第六指示信息的取值为第五数值,则指示所述资源池支持的PSFCH格式为所述第二PSFCH格式。例如,所述第四数值可以为1且所述第五数值可以为0。再如,所述第四数值可以为0且所述第五数值可以为1。
换言之,在所述资源池配置信息中包括一个信息域,所述一个信息域的长度为1比特,通过所述1比特可以显式的确定所述资源池支持的PSFCH格式。示例性地,所述1比特的取值为0表示支持所述第一PSFCH格式,取值为1表示支持所述第二PSFCH格式。
在一种实现方式中,所述第六指示信息为所述资源池配置信息中的用于配置所述PSFCH的频域资源的信息;若用于配置所述PSFCH的频域资源的信息为比特位图,则指示所述资源池支持的PSFCH格式为所述第一PSFCH格式;若用于配置所述PSFCH的频域资源的信息为用于指示起始频域位置和频域资源长度的信息,则指示所述资源池支持的PSFCH格式为所述第二PSFCH格式。

在一种实现方式中,若用于配置所述PSFCH的频域资源的信息为比特位图,则指示所述资源池支持的PSFCH格式为所述第一PSFCH格式;否则,则指示所述资源池支持的PSFCH格式为所述第二PSFCH格式。
示例性地,若用于配置所述PSFCH的频域资源的信息为通过比特位图形式指示的所述资源池配置信息中的侧行PSFCH资源块集合(sl-PSFCH-RB-Set),则指示所述资源池支持的PSFCH格式为所述第一PSFCH格式;否则,则指示所述资源池支持的PSFCH格式为所述第二PSFCH格式。
在一种实现方式中,所述方法100还可包括:
若所述资源池配置信息包括用于指示一个PSFCH占据的物理资源块PRB的个数的信息,则确定所述资源池支持的PSFCH格式为所述第二PSFCH格式;否则,确定所述资源池支持的PSFCH格式为所述第一PSFCH格式。
