技术领域
本公开涉及无线通信技术,具体涉及一种资源配置的指示方法、终端设备和存储介质。
背景技术
在车联网中,终端之间通过发送旁路(SL,SideLink)同步信号/广播信道块(SSB,Synchronization Signal and PBCH Block)实现同步。SSB中包括了旁路主同步信号(S-PSS,Sidelink-Primary Synchronization Signals)、旁路辅同步信号(S-SSS,Sidelink-Secondary Synchronization Signals)和物理旁路广播信道(PSBCH,Physical Sidelink Broadcast CHannel)。其中,PSBCH会承载时分双工(TDD,Time Division Duplex)配置的信息,以指示旁路传输资源。

则在一种可选实施方式中,所述传输周期包括:传输周期组合,所述时域资源单元数用于指示每个传输周期内的可用时隙数N i,其中,N i=M i*K i,M i为时域资源单元数,所述时域资源单元包含K i个时隙,所述K i个时隙对应的子载波间隔为F,所述K i是预先定义的正整数。在其他实施例中,所述传输周期也可仅包括传输周期,即针对单周期进行配置。
其中,示例性的,若所述传输周期组合包括两个传输周期,记为传输周期1和传输周期2,则终端设备可先在传输周期1对应的时长内按照对应的时域资源单元表示的可用时隙进行旁路传输,再按照传输周期2对应的时长内按照对应的时域资源单元表示的可用时隙进行旁路传输;再按照传输周期1对应的时长内按照对应的时域资源单元表示的可用时隙进行旁路传输,再按照传输周期2对应的时长内按照对应的时域资源单元表示的可用时隙进行旁路传输,以此类推。其中,示例性的,若针对单周期进行配 置,则可将上述传输周期组合包括的两个传输周期置为相同数值即可。
本实施例中,所述K i是预先定义的正整数。示例性的,若K i=1,则时域资源指示信息可用于指示传输周期组合中的周期i内的每个时域资源单元包含的1个时隙;若K i=2,则时域资源指示信息可用于指示传输周期组合中的周期i内的每个时域资源单元包含的2个时隙。可以理解,本实施例中的K i表示时域资源指示信息指示的颗粒度;例如时域资源指示信息指示传输周期内的1个时隙,或者指示传输周期内的2个时隙。在其他实施例中,所述可用时隙数N i还可以为所述终端设备所在的服务小区中的上行时域资源,也即为旁路可用时隙。本实施例通过适当的增大时域资源指示信息指示的颗粒度,减少时域资源指示信息所需的比特数。
可以理解,本实施例提供的技术方案,通过终端设备发送包含有传输周期和时域资源单元数的时域资源指示信息,即通过时域资源指示信息对传输周期和时隙数进行指示,将相关技术中的逐符号的指示改为逐时隙的指示上行资源,以对旁路的传输资源进行指示,大大降低了时域资源指示信息所需要的比特数,进而降低了PSBCH所需的比特数,从而避免了对旁路SSB的覆盖的影响。
在本公开的一些可选实施例中,如果所述传输周期组合不属于第一传输周期组合集合,K i=1,F为第一取值;如果所述传输周期组合属于所述第一传输周期组合集合,K i为预先定义的大于1的正整数,F为第一取值;或者,K i=1,F为第二取值。可选地,所述第一取值大于所述第二取值。在一些可选实施例中,所述第一取值为120千赫兹(KHz);所述第二取值为60KHz。
其中,所述第一传输周期组合集合包括以下至少部分传输周期组合:10毫秒(ms)传输周期和10毫秒传输周期、5毫秒传输周期和5毫秒传输周期、1毫秒传输周期和4毫秒传输周期、4毫秒传输周期和1毫秒传输周 期、2毫秒传输周期和3毫秒传输周期、3毫秒传输周期和2毫秒传输周期,1毫秒传输周期和3毫秒传输周期、3毫秒传输周期和1毫秒传输周期、2毫秒传输周期和2毫秒传输周期。
可以理解,为了保证时域资源指示信息所需的比特数,则所述第一传输周期组合集合包括的传输周期组合可选择上述列举的多个传输周期组合中的至少部分,具体选择上述哪些传输周期组合以作为所述第一传输周期组合,可根据实际需要确定,这里不再赘述。
可选地,所述第一传输周期组合集合为空集。
本实施例可包括以下场景:场景1:在第一传输周期组合集合为空集的情况下,即针对所有传输周期组合,在子载波间隔F为120KHz对应的可用时隙数的情况下,按照颗粒度为1(K i=1)进行指示,即时域资源指示信息指示到周期内的1个可用时隙。场景2:在第一传输周期组合集合为非空的情况下,在传输周期组合不属于第一传输周期组合集合的情况下,按照场景1的指示方式进行指示;在传输周期组合属于第一传输周期组合集合的情况下,在子载波间隔F为120KHz对应的可用时隙数的情况下,按照颗粒度为大于1的正整数进行指示,即时域资源指示信息指示到周期内的1个以上的可用时隙;或者在子载波间隔F为60KHz对应的可用时隙数的情况下,由于在相同传输周期内,60KHz对应的可用时隙数为120KHz对应的可用时隙数的一半,则按照颗粒度为1进行指示,即时域资源指示信息指示到传输周期内的1个可用时隙。
下面对上述场景进行举例说明。
示例一:
参照表2所示,本场景只指示传输周期组合和每个传输周期内的可用时隙数N i、且所述时域资源单元包含1个时隙(即K i=1)、所述1个时隙对应的子载波间隔F为120KHz的场景。本场景中的传输周期组合包括两个 传输周期,记为周期1和周期2,各个传输周期对应的时隙数如下表2所示,则对每个传输周期组合对应的状态数参照表2中最后一列所示。以周期1为0.5毫秒(ms)以及对应的时隙数为4、周期2为0.5ms以及对应的时隙数为4为例,由于还包括可用时隙数为0的情况,则对应的状态数为(4+1)×(4+1)=25,表明需要25个状态才能表示0.5ms和0.5ms传输周期组合的各种时隙数的组合情况。其他传输周期组合对应的状态数的确定方式参照上述方式,这里不再赘述。
由此可见,对于表2中所示的各种传输周期组合的情况,状态数的总数为11214,需要14个比特才能表示上述11214个状态。基于此,采用示例一的实现方式,可实现将时域资源指示信息的比特数压缩至14比特,相比于相关技术中的21比特,本实施方式减小了7个比特,大大减少了时域资源指示信息所需要的比特数,进而降低了PSBCH所需的比特数,从而避免了对旁路SSB的覆盖的影响。

在其他场景中,在传输周期组合属于第一传输周期组合集合的情况下,在子载波间隔F为120KHz对应的可用时隙数的情况下,按照颗粒度为大于1的正整数进行指示。以按照颗粒度为2进行指示为例,即K i=2,则状态数=(周期1时隙数/2+1)×(周期2时隙数/+1),假设表2中的周期1为10ms和周期2为10ms属于第一传输周期组合集合中的传输周期组合,则可确定对应的状态数为(80/2+1)×(80/2+1)=1681,相比于表2中周期1为10ms和周期2为10ms对应的状态数为6561,则采用本实施例的技术方案能够进一步的减少状态数,从而减少时域资源指示信息所需要的比特数。
在本公开的一些可选实施例中,如果所述传输周期组合不属于第一传输周期组合集合,K i=1,F为第一取值;如果所述传输周期组合属于第一传输周期组合集合、且所述传输周期组合中的第一传输周期和第二传输周期相同,K i为预先定义的大于1的正整数,F为第一取值;或者,K i=1,F为第二取值;如果所述传输周期组合属于第一传输周期组合集合、且所述传输周期组合中的第一传输周期和第二传输周期不同,所述第一传输周期对应的K 1=1,F为第一取值;所述第二传输周期对应的K 2为预先定义的大于1的正整数F为第一取值,或者,所述第二传输周期对应的K 2=1,F为第二取值。其中,所述第一传输周期小于所述第二传输周期。可选地,所述第一取值大于所述第二取值。在一些可选实施例中,所述第一取值为120 KHz;所述第二取值为60KHz。
可选地,所述第一传输周期组合集合为空集。
本实施方式在指示上行时隙数的基础上,为了进一步压缩时域配置信息,考虑在较大的传输周期组合或者传输周期组合中针对较大的传输周期增大指示颗粒度,在子载波间隔F为120KHz对应的可用时隙数的情况下,以预先定义的大于1的正整数F为颗粒度进行指示,即时域资源指示信息指示到传输周期内的1个以上可用时隙;或者在子载波间隔F为60KHz对应的可用时隙数的情况下,按照颗粒度为1(K i=1)进行指示,即时域资源指示信息指示到传输周期内的1个可用时隙。
本实施例可包括以下场景:场景1:在第一传输周期组合集合为空集的情况下,即针对所有传输周期组合,在子载波间隔F为120KHz对应的可用时隙数的情况下,按照颗粒度为1(K i=1)进行指示,即时域资源指示信息指示到周期内的1个可用时隙。本场景具体可参照前述示例一中所述,这里不再赘述。场景2:在第一传输周期组合集合为非空的情况下,在传输周期组合属于第一传输周期组合集合、且所述传输周期组合中的第一传输周期和第二传输周期相同的情况下,在子载波间隔F为120KHz对应的可用时隙数的情况下,按照颗粒度为大于1的正整数进行指示,即时域资源指示信息指示到周期内的1个以上的可用时隙;或者在子载波间隔F为60KHz对应的可用时隙数的情况下,按照颗粒度为1(K i=1)进行指示,即时域资源指示信息指示到传输周期内的1个可用时隙。场景3:在第一传输周期组合集合为非空的情况下,在传输周期组合属于第一传输周期组合集合、且所述传输周期组合中的第一传输周期小于第二传输周期的情况下,针对第一传输周期,在子载波间隔F为120KHz对应的可用时隙数的情况下,按照颗粒度为1(K i=1)进行指示,即时域资源指示信息指示到传输周期内的1个可用时隙,针对第二传输周期,在子载波间隔F为120KHz对应的 可用时隙数的情况下,按照颗粒度为大于1的正整数进行指示,即时域资源指示信息指示到周期内的1个以上的可用时隙;或者在子载波间隔F为60KHz对应的可用时隙数的情况下,按照颗粒度为1(K i=1)进行指示,即时域资源指示信息指示到传输周期内的1个可用时隙。
其中,所述第一传输周期组合集合包括以下至少部分传输周期组合:10毫秒传输周期和10毫秒传输周期、5毫秒传输周期和5毫秒传输周期、1毫秒传输周期和4毫秒传输周期、4毫秒传输周期和1毫秒传输周期、2毫秒传输周期和3毫秒传输周期、3毫秒传输周期和2毫秒传输周期,1毫秒传输周期和3毫秒传输周期、3毫秒传输周期和1毫秒传输周期、2毫秒传输周期和2毫秒传输周期。
下面对上述场景进行举例说明。
示例二
参照表3所示,本场景只指示传输周期组合和每个传输周期内的可用时隙数N i、且所述时域资源单元包含1个或2个时隙、时隙对应的子载波间隔F为120KHz的场景。本场景中的传输周期组合包括两个传输周期,记为周期1和周期2,各个传输周期对应的时隙数如下表2所示,则对每个传输周期组合对应的状态数参照表3中最后一列所示。
本示例适用于上述场景2和场景3。对于上述场景2,对于属于第一传输周期组合集合中的传输周期组合,且第一传输周期和第二传输周期相同的场景下,即周期1和周期2相同的情况下,例如10毫秒传输周期和10毫秒传输周期、5毫秒传输周期和5毫秒传输周期等等,则在子载波间隔F为120KHz对应的可用时隙数的情况下,按照颗粒度为大于1的正整数进行指示,即时域资源指示信息指示到周期内的1个以上的可用时隙;或者在子载波间隔F为60KHz对应的可用时隙数的情况下,按照颗粒度为1进行指示,即时域资源指示信息指示到传输周期内的1个可用时隙。例如, 周期1为10ms和周期2为10ms对应的状态数为(80/2+1)×(80/2+1)=1681。
对于上述场景3,对于属于第一传输周期组合集合中的传输周期组合,且第一传输周期和第二传输周期不同的场景下,例如:1毫秒传输周期和4毫秒传输周期、4毫秒传输周期和1毫秒传输周期、2毫秒传输周期和3毫秒传输周期、3毫秒传输周期和2毫秒传输周期等等,则对于较小的第一传输周期,在子载波间隔F为120KHz对应的可用时隙数的情况下,按照颗粒度为1进行指示,即时域资源指示信息指示到传输周期内的1个可用时隙;对于较大的第二传输周期,在子载波间隔F为120KHz对应的可用时隙数的情况下,按照颗粒度为大于1的正整数进行指示,即时域资源指示信息指示到周期内的1个以上的可用时隙;或者在子载波间隔F为60KHz对应的可用时隙数的情况下,按照颗粒度为1进行指示,即时域资源指示信息指示到传输周期内的1个可用时隙。例如,周期1为1ms和周期2为4ms对应的状态数为(8+1)×(32/2+1)=153。又例如,周期1为3ms和周期2为2ms对应的状态数为(24/2+1)×(16+1)=221。
由此可见,对于表3中所示的各种传输周期组合的情况,状态数的总数为3862,需要12个比特才能表示上述3862个状态。基于此,采用示例二的实现方式,可实现将时域资源指示信息的比特数压缩至12比特,相比于相关技术中的21比特,本实施方式减小了9个比特,大大减少了时域资源指示信息所需要的比特数,进而降低了PSBCH所需的比特数,从而避免了对旁路SSB的覆盖的影响。
可以理解,为了保证时域资源指示信息所需的比特数为12,则所述第一传输周期组合集合包括的传输周期组合可选择上述列举的多个传输周期组合中的至少部分,具体选择上述哪些传输周期组合以作为所述第一传输周期组合,可根据实际需要确定,这里不再赘述。示例性的,表3中所示 的周期1为2ms和周期2为2ms并未在所述第一传输周期组合集合中。

作为第三种实施方式,在前述第二种实施方式的基础上,通过增大指示的颗粒度,将时域资源指示信息压缩到13比特,本实施方式中进一步增大针对符号指示的颗粒度。在一些实施例中,所述可用符号数包括以下其中之一:13、10、小于7。示例性的,在可用时隙数为0的情况下,还可包括以下三种情况:0个时隙+13个符号、0个时隙+10个符号以及0个时隙+小于7个符号。在其他实施例中,所述可用符号数也可以是对应于三种状态的其他符号数组合,不限于上述13、10、小于7的符号数组合,本实施例中对可用符号数组合的具体形式不做限定。
基于此,本实施例中,传输周期组合对应的状态数=(周期1时隙数/2+3)×(周期2时隙数/2+3)。
下面对上述场景进行举例说明。

参照表6所示,本场景指示传输周期组合、每个传输周期内的可用时隙数N i以及可用时隙数为0对应的传输周期内的部分可用符号数,且所述时域资源单元包含2个时隙(即K i=2)、所述2个时隙对应的子载波间隔F为120KHz的场景。本场景中的传输周期组合包括两个传输周期,记为周期1和周期2,各个传输周期对应的时隙数如下表6所示,则对每个传输周期组合对应的状态数参照表6中最后一列所示。
由此可见,对于表6中所示的各种传输周期组合的情况,状态数的总数为3703,需要12个比特才能表示上述3703个状态。基于此,采用示例五的实现方式,可实现将时域资源指示信息的比特数压缩至12比特,大大减少了时域资源指示信息所需要的比特数,进而降低了PSBCH所需的比特数,从而避免了对旁路SSB的覆盖的影响;相比于相关技术中的21比特,本实施方式减小了9个比特,并且在前述实施例的基础上,通过指示到部分符号,在一定程度上也提升了时域资源指示信息的指示颗粒度。

可以理解,本公开实施例中,用于指示传输周期和时域资源单元数的时域资源指示信息可通过表示对应的传输周期和时域资源单元数的比特值表示。示例性的,若以表2所示的14比特数为例,则可通过14位比特中的各种取值对应表2中的各传输周期组合以及每个传输周期组合内的各个时隙数组合。各传输周期组合以及每个传输周期组合内的各个时隙数组合对应的比特取值可通过映射表实现,则终端设备可通过查找映射表,确定 时域资源指示信息中的传输周期组合和每个传输周期内的可用时隙数Ni对应的状态标识,再根据状态标识确定对应的比特取值。
在车联网中,终端设备通过基站(如图1中的eNB)发送的信令或预配置确定资源,再基于该资源确定旁路实际可用的资源。基于此,在所述时域资源指示信息用于指示传输周期组合和每个传输周期内的可用时隙数N i的情况下,即时域资源指示信息指示的颗粒度为时隙的情况下,对于指示0时隙的情况,只表明并没有完整可用的时隙。此时,终端设备可根据PSSCH配置的资源确定旁路实际可用的时域资源,也即只需要保证PSSCH配置的资源与时域资源指示信息不冲突即可。
在所述时域资源指示信息用于指示传输周期组合、每个传输周期内的可用时隙数N i以及可用时隙数为0对应的传输周期内的可用符号数情况下,对于指示0时隙+可用符号数的情况,接收侧的终端设备需要根据PSSCH配置的资源与PSBCH中指示的资源(即时域资源指示信息指示的时域资源)之间取交集来确定旁路的实际可用资源。
