Description
本申请要求于2020年02月06日提交的申请号为PCT/CN2020/074441、申请名称为“侧行链路配置授权的配置方法、设备及存储介质”的专利申请,以及于2020年04月01日提交的申请号为PCT/CN2020/082818、申请名称为“侧行链路配置授权的配置方法、设备及存储介质”的专利申请,以及于2020年04月02日提交的申请号为PCT/CN2020/083031、申请名称为“侧行链路配置授权的配置方法、设备及存储介质”的专利申请的优先权,其全部内容通过引用结合在本申请中。
本申请实施例涉及通信技术,尤其涉及一种侧行链路配置授权的配置方法、设备及存储介质。
随着通信技术的发展,车联万物(Vehicle‐to‐Everything,简称V2X)技术的应用越来越广泛。V2X采用设备到设备(Device‐to‐Device,D2D)通信方式,是一种基于侧行链路传输技术(Sidelink,SL)的通信方式,因此具有更高的频谱效率以及更低的传输时延。
在新无线(New Radio,NR)车联网中,支持以下两种资源分配方式。一种方式,终端在资源池自主选取传输资源进行侧行链路传输;另一种方式,网络为终端分配侧行链路传输资源,具体的,网络可以通过动态调度(Dynamic Scheduling)的方式为终端分配侧行链路传输资源;或者网络可以为终端分配侧行链路配置授权(Configured Grant,CG)传输资源。对于CG的资源分配方式,主要包括两种:第一类配置授权type‐1 CG和第二类配置授权type‐2 CG。
对于网络为终端分配侧行链路CG传输资源的方式,网络在给终端的CG传输资源的配置信令中至少包括如下参数:时隙偏移量和周期,终端根据时隙偏移量和周期,确定CG传输资源的时域位置;其中时隙偏移量,是指第一个CG传输资源的时隙相对于***帧号(System Frame Number,SFN)周期(或直接帧号(Direct Frame Number,DFN)周期)中第一个时隙偏移的时隙个数;周期是指侧行链路配置授权传输资源的周期。上述方案中,在不同的SFN周期(或DFN周期)中可用的CG传输资源对应着不同的时域位置。例如,在图1中,资源池在一个SFN周期包含3033个时隙,如果配置参数中时隙偏移量是2,周期是4,则在第一个SFN周期中CG传输资源的可用时隙分别是时隙2、6、10、…、3030,在第二个SFN周期中CG传输资源的可用时隙分别是时隙1、5、9、…、3029,以此类推。因此,如果配置信令在跨SFN周期边界的时候传输了至少两次(包括首次传输和重传),终端不知道此时配置信令中的时隙偏移量参数是针对哪个SFN周期的第一个时隙的。假设网络首次在第一个SFN周期发送的配置信令,但是终端是在第二个SFN周期接收到重传的该配置信令,则终端不清楚第二个SFN周期中侧行链路配置授权传输资源的可用时隙是1、5、9、…、3029,还是2、6、10、…、3030。因此,终端设备确定的配置授权传输资源的可用时隙可能不准确。

当前车联万物(Vehicle‐to‐Everything,简称V2X)技术的应用越来越广泛。采用设备到设备(Device‐to‐Device,D2D)通信方式,是一种基于侧行链路传输技术(Sidelink,SL)的通信方式,因此具有更高的频谱效率以及更低的传输时延。
在新无线(New Radio,NR)车联网(NR‐V2X)中,支持以下两种资源分配方式。一种方式,终端在资源池自主选取传输资源进行侧行链路传输;另一种方式,网络为终端分配侧行链路传输资源,具体的,网络可以通过动态调度(Dynamic Scheduling)的方式为终端分配侧行链路传输资源;或者网络可以为终端分配侧行链路配置授权(Configured Grant,CG)传输资源。对于CG的资源分配方式,主要包括两种:第一类配置授权type‐1 CG和第二类配置授权type‐2 CG。
type‐1 CG:网络通过无线资源控制(Radio Resource Control,RRC)信令为终端配置侧行链路传输资源,该RRC信令配置包括时域资源、频域资源、解调用参考信号(Demodulation Reference Signal,DMRS)、调制编码方式(Modulation and coding scheme,MCS)等在内的全部传输资源和传输参数。当终端接收到该高层信令后,可立即使用所配置的传输参数在配置的时频资源上进行侧行链路传输。
type‐2 CG:采用两步的资源配置方式,即RRC+下行链路控制信息(Downlink Control Information,DCI)的方式;首先,由RRC信令配置包括时频资源的周期、冗余版本、重传次数、混合自动重传请求(Hybrid Automatic Repeat reQuest,HARQ)进程数等在内的传输资源和传输参数,然后由DCI激活type‐2 CG的传输,并同时配置包括时域资源、频域资源、MCS等在内的其他传输资源和传输参数。终端在接收到RRC信令时,不能立即使用该高层信令配置的资源和参数进行侧行链路传输,而必须等接收到相应的DCI激活并配置其他资源和传输参数后,才能进行侧行链路传输。
其中,网络侧为终端分配的侧行链路CG传输资源是从资源池中分配的,资源池为可用于侧行传输的资源集合,在一实施例中,网络侧可以通过配置信息为终端配置资源池。
以下以SFN周期为例进行说明,一个SFN周期包括10240个子帧,分别对应子帧0、1、2、…、10239;去掉同步子帧、下行子帧、特殊子帧,剩余的子帧重新编号为
N
S-SSB表示同步子帧的数量,N
dssf表示下行子帧和特殊子帧的数量。若r满足以下条件,子帧l
r(0≤r<(10240-N
S-SSB-N
dssf))属于预留子帧:
其中,m=0,...,N
reserved-1,N
reserved=(10240-N
S-SSB-N
dssf)mod L
bitmap。L
bitmap表示用于指示资源池时域资源的比特位图的长度。
终端按照如下方式确定资源池:
一个SFN周期包括的子帧总数10240,去掉同步子帧、下行子帧、特殊子帧和预留子帧,剩余的子帧重新编号为
剩余的子帧的个数能够被L
bitmap整除,比特位图
在剩余的子帧中周期重复,比特为1表示该比特在该剩余子帧中对应的子帧属于该资源池,否则不属于该资源池。
对于子载波间隔是15kHz来说,一个SFN周期内的子帧和时隙数量是相同的,因此以下实施例中以时隙为例进行说明,本申请以下实施例中均以子载波间隔是15kHz为例进行说明,对于其他子载波间隔情况类似。
在一实施例中,一个SFN周期中有N
RP,slot个时隙属于该资源池,该资源池中时隙的个数可以通过 如下参数中的至少一个确定:一个SFN周期中包括的总时隙个数,一个SFN周期中用于同步信号占用的时隙数,预留时隙的个数,不可用于侧行传输的时隙的个数,比特位图的长度,比特位图中取值为特定值的比特位的个数。其中,不可用于侧行传输的时隙例如是TDD***中的下行子帧或特殊子帧,或者是NR***中网络配置的全下行时隙等。
例如N
RP,slot通过如下公式计算得到:
N
RP,slot=(N
slot-N
S-SSB-N
reserved)/L
bitmap×N
bit-one
其中:N
slot表示一个SFN周期包括的所有的时隙的总数量,例如,N
slot=10240×2
μ,μ=0、1、2、3、4,分别对应子载波间隔是15、30、60、120和240kHz,N
S-SSB表示一个SFN周期中包括的用于侧行同步信号块(Sidelink Synchronization Signal Block,S‐SSB)传输的时隙数量;N
reserved表示一个SFN周期中包括的预留时隙数量,L
bitmap表示用于指示资源池时域资源的比特位图的长度;N
bit-one表示比特位图中取值为1的比特的数量(取值为1表示该比特对应的时隙属于该资源池,取值为0表示该比特对应的时隙不属于该资源池),或者在其他实施例中也可以为取值为预设值的比特的数量,本申请实施例对此并不限定。
如图1所示,一个SFN周期包括10240个时隙,同步信号的周期是160ms,在一个同步周期内包括2个同步时隙,因此,在一个SFN周期内共有128个同步时隙,用于指示资源池时域资源的比特位图的长度是10比特,因此需要2个预留时隙,剩余时隙个数是(10240‐128‐2=10110),可以被比特位图的长度10整除,将剩余的时隙重新编号为0、1、2、…、10109,比特位图前3位为1,其余7位为0,即在剩余时隙中,每10个时隙中的前3个时隙属于该资源池,其余的时隙不属于该资源池。由于在剩余时隙中需要比特位图重复1011次,以指示所有的时隙是否属于资源池,而在每个比特位图周期内包括3个时隙,因此在一个SFN周期共有3033个时隙属于该资源池。
对于type‐1 CG的资源分配方式,网络在给终端的CG传输资源的配置信令中至少包括如下参数:时隙偏移量和周期,根据时隙偏移量和周期,确定CG传输资源的时域位置;其中时隙偏移量,是指第一个CG传输资源的时隙相对于***帧号(System Frame Number,SFN)周期(或直接帧号(Direct Frame Number,DFN)周期)中第一个时隙偏移的时隙个数;周期,是指侧行链路配置授权传输资源的周期。上述方案中,在不同的SFN周期中可用的CG传输资源对应着不同的时域位置。例如,在图1中,资源池在一个SFN周期包含3033个时隙,如果配置参数中时隙偏移量是2,周期是4,则在第一个SFN周期中CG传输资源的可用时隙分别是时隙2、6、10、…、3030,在第二个SFN周期中CG传输资源的可用时隙分别是时隙1、5、9、…、3029,以此类推。因此,如果配置信令在跨SFN周期边界的时候传输了至少两次(包括首次传输和重传),终端不知道此时配置信令中的时隙偏移量参数是针对哪个SFN周期的第一个时隙的。假设网络首次在第一个SFN周期发送的配置信令,但是终端是在第二个SFN周期接收到重传的该配置信令,则终端不清楚第二个SFN周期中侧行链路配置授权传输资源的可用时隙是1、5、9、…、3029,还是2、6、10、…、3030。因此,终端设备确定的配置授权传输资源的可用时隙可能不准确。
下面以具体的实施例对本申请的技术方案进行详细说明。下面这几个具体的实施例可以相互结合,对于相同或相似的概念或过程可能在某些实施例不再赘述。
图2为本申请实施例所应用的一种通信***的示意图。如图2所示,该通信***中至少包括网络设备11和终端设备12。可以理解的是,在实际通信***中,网络设备11以及终端设备12均可以有一个或多个,该图1网络设备以一个作为示例,终端设备12以两个作为示例。
在图2中,网络设备11可以是接入网设备,例如可以是LTE网络及其演进网络中的接入设备,例如演进型基站(Evolutional Node B,简称eNB或eNodeB),或者也可以包括5G NR***中的下一代节点B(next generation node B,gNB),或者中继站,或者未来新的网络***中的基站等等。
终端设备12,也可以称为移动终端、用户设备(User Equipment,简称:UE)、接入终端、用户单元、用户站、移动站、移动台、用户终端、终端、无线通信设备、用户代理或用户装置。具体可以是智能手机、蜂窝电话、无绳电话、个人数字处理(Personal Digital Assistant,简称:PDA)设备、具有无线通信功能的手持设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备等。在本申请实施例中,该终端设备具有与网络设备进行通信的接口。
本申请实施例的方法的发明构思如下:网络设备确定的配置授权传输资源的参数,可以保证不同SFN周期(或DFN周期)中可用的CG传输资源具有相同的时域位置,例如图3中,在SFN周期1中CG传输资源的可用时隙分别是时隙2、5、8、…、3032,在SFN周期2中CG传输资源的可用时隙分别是时隙2、5、8、…、3032,后面的SFN周期中可用时隙也均是时隙2、5、8、…、3032。
下面以具体的实施例对本申请的技术方案进行详细说明。下面这几个具体的实施例可以相互结合, 对于相同或相似的概念或过程可能在某些实施例不再赘述。
图4为本申请提供的配置方法一实施例的交互流程图,如图4所示,本实施例的具体实现步骤包括:
步骤101、网络设备发送用于确定侧行链路配置授权CG传输资源的参数,CG传输资源在不同的帧周期中具有相同的时域位置。
在一实施例中,帧周期为***帧号SFN周期或直接帧号DFN周期。下面的实施例中以帧周期是SFN周期为例进行说明。
例如,在一个SFN周期内,CG传输资源的时域资源分别是时隙C1、C2、C3,以此类推,其中C1是该SFN周期内一个资源池中第一个CG传输资源的时域位置,C2、C3、…等后续的资源是根据C1的时域资源以及侧行链路CG传输资源的周期确定的。在不同的SFN周期内,CG传输资源是该SFN周期内时隙C1、C2、C3、…对应的传输资源,即不同的SFN周期内,CG传输资源的时域位置(即时域的相对位置)是相同的。
为了满足CG传输资源在不同的帧周期中具有相同的时域位置,在一实施例中,网络设备配置的该参数需要满足如下预设条件:一个帧周期内属于第一资源池的时隙的总数量能被所述CG传输资源的周期整除。
第一资源池为可用于侧行传输的资源集合,CG传输资源是属于第一资源池的传输资源。
在一实施例中,该预设条件可以通过如下的公式(或该公式的其他变形)体现:
mod(N
RP,slot,P)=0
其中:N
RP,slot表示一个帧周期内属于第一资源池的时隙的总数量,mod()表示取余数运算。
在一实施例中,网络侧可以通过配置信息为终端设备配置第一资源池,第一资源池中的传输资源可用于终端设备进行侧行传输,网络侧从第一资源池中为终端设备分配侧行链路CG传输资源。
其中,该N
RP,slot参数可以根据以下至少一项参数确定,至少一项参数包括:帧周期内的原始时隙总数量,该原始时隙总数量为10240×2
μ,其中参数μ是根据子载波间隔确定的,μ=0、1、2、3、4,分别对应子载波间隔是15、30、60、120和240kHz;帧周期内用于传输同步信号块的时隙数量;帧周期内的预留时隙数量;不可用于侧行传输的时隙数量;比特位图中取值为预设值的比特的数量和比特位图的长度。其中,比特位图中取值为预设值的比特的数量,例如为比特位图中比特位为1的比特个数。
P表示CG传输资源的周期,以时隙为单位。
在一实施例中,该用于确定CG传输资源的参数,还包括:时隙偏移量N
offset,其中,针对任一所述帧周期,所述时隙偏移量用于确定所述帧周期中属于所述第一资源池的第一个CG传输资源的时域位置,N
offset表示第一个CG传输资源相对于该帧周期内属于该第一资源池的第一个时隙的时隙偏移量,用于确定每个帧周期中第一个CG传输资源的时隙位置。
在一实施例中,时隙偏移量N
offset的取值范围为[0,P-1]。时隙偏移量可以通过时隙个数表示。
在一实施例中,如图3所示,如果网络配置的CG传输资源的参数N
offset=2,表示第一个CG传输资源的时隙相对于帧周期中该第一资源池的第一个时隙的偏移是2个时隙,即第一个CG传输资源的时隙是该帧周期内属于第一资源池的第2个时隙(时隙编号从0开始),CG传输资源的周期P=3。
根据上述参数配置,在一个SFN周期中,侧行链路CG传输资源分别对应该第一资源池中的时隙2、5、8、11、……、3032;进一步的,由于满足上述预设条件,因此,在不同SFN周期中,侧行链路CG传输资源的时域位置相同。
上述实施方式中,用于确定CG传输资源的参数(如CG传输资源的周期)和资源池时域资源的参数(如帧周期内属于第一资源池的时隙的总数量)之间需要满足的特定关系,使得在不同帧周期内CG传输资源的时域资源是相同的。
步骤102、终端设备根据该参数,确定CG传输资源。
终端设备接收网络设备发送的上述用于确定CG传输资源的参数,根据该参数,确定可用的CG传输资源,并利用CG传输资源传输数据。
本实施例的方法,网络设备发送用于确定侧行链路配置授权CG传输资源的参数,终端设备根据该参数确定的CG传输资源在不同的帧周期中具有相同的时域位置,因此终端设备无论在哪个帧周期接收到网络设备发送的参数,都能准确的确定出CG传输资源的时域位置。
在一实施例中,该方法还包括:
网络设备发送第一配置信息,第一配置信息用于确定至少一个第二资源池,至少一个第二资源池包括第一资源池;CG传输资源是属于第一资源池的传输资源。
在一实施例中,第一配置信息可以是无线资源控制RRC信令或***信息块(System Information Block,SIB)。
具体的,第一资源池可以通过网络设备发送的第一配置信息确定,该CG传输资源为该第一资源池中的传输资源。
其中,第一配置信息可以配置至少一个第二资源池,该至少一个第二资源池包括该第一资源池,第一配置信息例如用于指示第二资源池包含的资源的信息。
在一实施例中,步骤101可以通过如下方式实现:
网络设备发送第二配置信息,第二配置信息包括该用于确定CG传输资源的参数。
在一实施例中,第二配置信息是无线资源控制RRC信令或下行链路控制信息DCI信令。
其中,第一配置信息和第二配置信息可以是同一配置信息或不同配置信息,本申请实施例对此不做限定。
在一实施例中,对于type-1 CG,网络设备可以通过第二配置信息发送上述用于确定CG传输资源的参数,例如包括CG传输资源的参数、时隙偏移量。
例如,如果网络配置的CG传输资源的周期是3个时隙,时隙偏移量为2个时隙,则终端设备确定的属于该第一资源池中可用于侧行传输的时隙为{2、5、8、11、……、3032},每个帧周期中时域位置相同,即对于所有的帧周期中属于该第一资源池中可用于侧行传输的时隙均为{2、5、8、11、……、3032}。
在一实施例中,对于type-2 CG,网络设备通过RRC信令(或其他高层信令)发送CG传输资源的周期,网络发送DCI用于确定帧周期中属于该第一资源池的第一个CG传输资源的时域位置,例如接收到DCI的时隙为第一个CG传输资源的时域位置。例如,如果网络配置的CG传输资源的周期是3个时隙,接收到DCI的时隙为当前帧周期中的时隙7,则终端设备确定的当前帧周期中属于该第一资源池的可用于侧行传输的时隙为{7、10、13、17、……、3031},对于之后的其他帧周期中属于该第一资源池的可用于侧行传输的时隙为{1、4、7、10、13、17、……、3031}。
在另一实施例中,对于type-2 CG,网络设备通过RRC信令(或其他高层信令)发送CG传输资源的周期,网络发送DCI用于确定帧周期中属于该第一资源池的第一个CG传输资源的时域位置,例如通过DCI指示时隙偏移量,用于指示该帧周期中属于该第一资源池的第一个CG传输资源的时隙,相对于接收到该DCI的时隙偏移的时隙个数。终端设备通过接收到该DCI的时隙以及时隙偏移量,确定第一个CG传输资源的时隙的位置。例如,如果网络配置的CG传输资源的周期是3个时隙,接收到DCI的时隙为当前帧周期中的时隙7,时隙偏移量为2,则终端设备确定的当前帧周期中第一个CG传输资源为时隙9,该帧周期属于该第一资源池的可用于侧行传输的时隙为{9、12、15、18、……、3030},对于之后的其他帧周期中属于该第一资源池的可用于侧行传输的时隙为{0、3、6、9、12、15、18、……、3030}。
在一实施例中,对于侧行传输和上行传输共享载波的情况,侧行传输只能使用上行时隙或上行符号资源,此时,上述帧周期内的原始时隙总数量N
slot表示一个帧周期中可用于侧行传输的上行时隙的个数。
进一步,可以包含以下几种具体实现方式:
一种情况,上行时隙中的符号全部为上行符号时,才可用于侧行传输;
另一种情况,上行时隙中部分符号是上行符号时也可以用于侧行传输。进一步的,上行时隙中上行符号的数量大于预设值,该预设值例如为网络配置的预设值,例如为7,则只有当一个上行时隙中的上行符号的个数大于或等于7时,该上行时隙才是可用于侧行传输的时隙,否则是不可用的时隙。
在其他实施例中,该预设值可以是预先定义的,或通过其他方式确定的,本申请对此并不限定。

在一实施例中,网络配置的用于确定CG传输资源的参数是基于第一资源池中的时隙确定的,即基于第一资源池的逻辑时隙确定的。
物理时隙是基于实际的时间确定的时隙位置,例如,图3中一个SFN周期中的时隙0、1、2、…、10239,即对应物理时隙的索引;
逻辑时隙是基于第一资源池中的资源确定的时隙位置,例如,图3中第一资源池中的资源所对应的时隙即是逻辑时隙,其中,逻辑时隙0对应物理时隙0,逻辑时隙1对应物理时隙2(因为物理时隙1是用于传输同步信号块的时隙,不属于资源池的资源),逻辑时隙2对应物理时隙4(因为物理时隙 3是用于传输同步信号块的时隙,也不属于资源池的资源)。
上述CG传输资源的周期P,以及时隙偏移量均基于第一资源池的逻辑时隙。
上述实施方式中,终端设备根据网络设备发送的参数确定的CG传输资源在不同的帧周期中具有相同的时域位置,因此终端设备无论在哪个帧周期接收到网络设备发送的参数,都能准确的确定出CG传输资源的时域位置。
