Description

指示频域资源的方法、终端设备和网络设备 技术领域
本申请实施例涉及通信领域,并且更具体地,涉及一种指示频域资源的方法、终端设备和网络设备。
背景技术
随着移动通信技术的发展,第五代移动通信技术(fifth generation,5G)中,网络设备可以为终端设备动态地分配不同子载波间隔的时频资源,如何指示为终端设备分配的不同子载波间隔的时频资源,并避免造成很大的控制信令开销,是一个需要解决的问题。
发明内容
本申请实施例提供了一种指示频域资源的方法,终端设备和网络设备,以实现多种子载波间隔的资源的指示,并节省信令开销。
第一方面,提出了一种指示频域资源的方法,该方法包括:终端设备接收网络设备发送的第一指示信息,所述第一指示信息以第一单元为粒度指示系统频域资源中的资源区域是否包含所述网络设备从所述系统频域资源中为所述终端设备分配的目标频域资源,其中,所述系统频域资源包括多种频域资源,所述多种频域资源分别具有不同的子载波间隔,所述多种频域资源分别由不同大小的最小频域调度单元组成,所述资源区域的大小与所述第一单元相同,所述第一单元的大小为第二子载波间隔的频域资源的最小频域调度单元的M倍,M为大于等于1的整数,第二子载波间隔大于所述目标频域资源的子载波间隔;所述终端设备根据所述第一指示信息确定所述目标频域资源所处的资源区域。
第一指示信息指示包含目标频域资源的区域时采用的指示单位是大于目标频域资源的最小频域调度单元的,而现有技术在指示频域资源时采用的指示单位的大小是与频域资源的最小频域调度单元相同的,因此,与现有技术相比,本申请实施例是采用较大的指示单元对频域资源进行指示,能够节省一定的信令开销。
结合第一方面,在第一方面的某些实现方式中,所述资源区域包含所述 目标频域资源,所述方法还包括:所述终端设备接收所述网络设备发送的第二指示信息,所述第二指示信息以第二单元为粒度指示所述资源区域中的每个子区域中的频域资源是否属于所述目标频域资源,所述子区域的大小与所述第二单元的大小相同,所述第二单元的大小与所述目标频域资源的最小频域调度单元相同。
通过第一指示信息的粗指示能够在系统频域资源上指示出目标频域资源所处的资源区域,而通过第二指示信息的细指示能够指示资源区域中的每个子区域中的频域资源是否属于目标频域资源,这样通过分层指示的方式能够实现对多种子载波间隔的频域资源的指示,并且与现有技术中直接采用频域资源的最小频域调度单元为粒度来指示的方式相比,能够节省一定的信令开销,尤其是当目标频域资源占系统频域资源的比例较小时能够节省更多的信令开销。
结合第一方面,在第一方面的某些实现方式中,所述第一指示信息和所述第二指示信息为比特图信息。
通过比特图信息能够方便灵活地实现对频域资源的指示,如采用0或1就能直接指示某个资源区域中是否包含目标资源。
结合第一方面,在第一方面的某些实现方式中,所述资源区域包括多个子区域,所述第二指示信息包含多个比特位,所述多个比特位中的每个比特位对应所述多个子区域中的一个子区域,当所述第二指示信息中的第一比特位为第一取值时,与所述第一比特位对应的子区域包含的频域资源属于所述目标频域资源,其中,所述第一比特位为所述多个比特位中的任意一个。
当第一指示信息以较大的频域单元指示出了包含目标频域资源的资源区域之后,第二指示信息只需要以较小的频域单元在系统频域资源中包含目标频域资源的资源区域再进行“细指示”即可,而不用现有技术那样,需要采用较小的频域单元在整个系统资源中对目标频域资源进行细指示,能够节省信令开销,并且在目标频域资源仅占系统频域资源很小比例时,与现有技术相比,节省的信令开销更加明显。
结合第一方面,在第一方面的某些实现方式中,所述目标频域资源包括第一频域资源和第二频域资源,所述第一频域资源的子载波间隔小于所述第二频域资源的子载波间隔,所述第一指示信息用于以所述第一单元指示所述系统频域资源中的资源区域是否包含第一频域资源和第二频域资源,所述第 二子载波间隔大于或者等于所述第二频域资源的子载波间隔。
当目标频域资源包含两种频域资源时,第一指示信息能够同时指示包含这两种频域资源的区域,实现了对两种频域资源的联合指示。同样,当目标频域资源还包括除第一频域资源和第二频域资源之外的其它种类的频域资源时,第一指示信息能够实现对目标频域资源中多种频域资源的联合指示。
结合第一方面,在第一方面的某些实现方式中,所述资源区域包含所述第一频域资源或者第二频域资源,所述方法还包括:所述终端设备接收所述网络设备发送的第二指示信息,所述第二指示信息以所述第二单元为粒度指示所述资源区域的每个子区域中的频域资源是否属于第一频域资源或者第二频域资源,所述子区域的大小与所述第二单元的大小相同,所述第二单元的大小与所述第一频域资源的最小频域调度单元相同。

第二指示信息的比特位的不同取值能够指示出资源区域中的各个子区域中的频域资源具体属于第一频域资源还是第二频域资源,能够在系统频域资源中准确地为终端指示出这两种频域资源。
结合第一方面,在第一方面的某些实现方式中,所述第二取值为0。
结合第一方面,在第一方面的某些实现方式中,所述方法还包括:所述终端设备接收所述网络设备发送的资源种类信息;所述终端设备根据所述资源种类信息确定所述目标频域资源包含的频域资源的种类。
资源种类信息能够直接指示为终端分配了哪几种频域资源,便于终端设备根据该资源种类信息快速确定目标频域资源包含的资源的种类。
第二方面,提出了一种指示频域资源的方法,该方法包括:终端设备接收所述网络设备发送的资源位置指示信息;所述终端设备接收所述终端设备发送的资源类别指示信息;所述终端设备根据所述资源位置指示信息确定目标频域资源在系统频域资源中所处的位置,其中,所述目标频域资源为网络设备从多种频域资源中为所述终端设备分配的频域资源,不同种类的频域资 源的子载波间隔不同;所述终端设备根据所述资源类别指示信息确定所述目标频域资源包含的频域资源的种类。
网络设备通过资源类别指示信息能够指示为终端设备分配的频域资源的资源种类,可以实现对多种子载波间隔的频域资源的指示。
结合第二方面,在第二方面的某些实现方式中,所述目标频域资源包括M种频域资源,所述资源位置指示信息包括M个位置指示信息,所述M个位置指示信息依次指示所述M种频域资源在系统频域资源中所处的位置,所述资源种类指示信息包括M个种类指示信息,所述M个种类指示信息依次指示所述M种频域资源的资源种类,M为大于等于1的整数。
当目标频域资源包含多种频域资源时,通过多个位置指示信息和多个种类指示信息,能够较为方便地指示出目标频域资源包含的频域资源的种类和位置。
第三方面,提出了一种指示频域资源的方法,该方法包括:网络设备生成第一指示信息,所述第一指示信息以第一单元为粒度指示系统频域资源中的资源区域是否包含所述网络设备从所述系统频域资源中为所述终端设备分配的目标频域资源,其中,所述系统频域资源包括多种频域资源,所述多种频域资源分别具有不同的子载波间隔,所述多种频域资源分别由不同大小的最小频域调度单元组成,所述资源区域的大小与所述第一单元相同,所述第一单元的大小为第二子载波间隔的频域资源的最小频域调度单元的M倍,M为大于等于1的整数,第二子载波间隔大于所述目标频域资源的子载波间隔;所述网络设备向所述终端设备发送第一指示信息
第一指示信息指示包含目标频域资源的区域时采用的指示单位是大于目标频域资源的最小频域调度单元的,而现有技术在指示频域资源时采用的指示单位的大小是与频域资源的最小频域调度单元相同的,因此,与现有技术相比,本申请实施例是采用较大的指示单元对频域资源进行指示,能够节省一定的信令开销。

应理解,本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”,仅仅是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。另外,本文中字符“/”,一般表示前后关联对象是一种“或”的关系。
在现有技术中,当网络设备为终端设备分配多种不同子载波间隔的频域资源时,网络设备利用多种不同的指示信息分别以不同的粒度指示不同子载波间隔的频域资源。例如,网络设备为终端设备分配了第一频域资源、第二频域资源和第三频域资源,其中,第一频域资源的子载波间隔为f1,组成第一频域资源的资源块的大小为R1,第二频域资源的子载波间隔为f2,组成第二频域资源的资源块的大小为R2,第三频域资源的子载波间隔为f3,组成第三频域资源的资源块的大小为R3,f1>f2>f3,R1>R2>R3,网络设备分别采用三个字段来分别指示这三种频域资源,其中,这三个字段分别以R1、R2和R3为粒度在系统频域资源上分别指示第一频域资源、第二频域资源和第三频域资源的位置。由于R1>R2>R3,那么从第一字段到第三字段,字段占用的比特位越来越多。下面结合图2对现有的资源指示方式进行详细的描述。
图2是现有技术中的资源指示方法分别指示两种子载波间隔不同的频域资源的示意图。图2中示出了第一频域资源和第二频域资源在整个系统频域资源中的分布情况,其中,第一频域资源和第二频域资源的子载波间隔分别为f1和f2,第一频域资源和第二频域资源分别由R1和R2大小的资源块组成,并且f2=2f1,R2=2R1。在图2中,网络设备分别以R1和R2将系统频域资源划分成了多个资源区域,其中,每个资源区域中用比特位0或1指示该资源区域中是否存在相应的资源。
当网络设备为终端设备分配第二频域资源时,可以向终端设备发送包含字段(0100100010)的第二指示信息,以指示第二频域资源在整个系统频域资源中所处的位置,其中比特位的取值为1的资源区域中的频域资源属于第二频域资源,比特位的取值为0的资源区域中的频域资源不属于第二频域资源。
当网络设备为终端设备分配第一频域资源时,可以向终端设备发送包含字段(10000100000010000000)的第一指示信息,以指示第一频域资源在整个系统频域资源中所处的位置,其中比特位的取值为1的资源区域中的频域资源属于第一频域资源,比特位的取值为0的资源区域中的频域资源不属于第一频域资源(该资源区域的频域资源可以是预留的频域资源也可以是已经分配出去的频域资源)。
网络设备在指示这两种频域资源时划分的资源区域的大小不同,在指示第一频域资源时划分的资源区域的大小与第一频域资源的最小频域调度单元相同,在指示第二频域资源时划分的资源区域的大小与第二频域资源的最小频域调度单元相同。由于R2小于R1,因此第二指示信息的字段占用的比特位要远远大于第一指示信息的字段占用的比特位,并且,当组成频域资源的资源块越小时越需要使用更多的字段来指示频域资源,这会造成大量的信令开销。
另外,在图2中,如果网络设备为终端设备同时分配了第一频域资源和第二频域资源,那么网络设备可以向同时或者依次向终端设备发送第一指示信息和第二指示信息,以指示这两种频域资源在系统频域资源中的位置。
应理解,在图2中为了便于说明问题,将系统频域资源设置的很小,实际上网络设备为终端设备分配的频域资源只占整个系统频域资源的很小一部分,也就是说大部分资源区域中是不包含网络设备为终端设备分配的频域 资源的,因此,采用图2所示的方式指示频域资源时,指示信息中将会包含大量比特位为0的字段,会造成较大的信令开销。
为此,本申请实施例提出了一种新的频域资源的指示方法,在指示频域资源时,先以较大粒度的单元来“粗指示”目标频域资源,再以较小粒度的单元“细指示”目标频域资源,以节省指示频域资源时的信令开销。下面结合图3至图8对本申请实施例的指示频域资源的方法进行详细的描述。
图3是本申请实施例的指示频域资源的方法的示意性流程图。图3的方法300包括:
310、终端设备接收网络设备发送的第一指示信息,第一指示信息以第一单元为粒度指示系统频域资源中的资源区域是否包含网络设备从系统频域资源中为终端设备分配的目标频域资源;
其中,系统频域资源包括多种频域资源,该多种频域资源分别具有不同的子载波间隔,多种频域资源分别由不同大小的最小频域调度单元组成,资源区域的大小与第一单元相同,第一单元的大小为第二子载波间隔的频域资源的最小频域调度单元的M倍,M为大于等于1的整数,第二子载波间隔大于目标频域资源的子载波间隔;
320、终端设备根据第一指示信息确定目标频域资源所处的资源区域。
上述目标频域资源可以是一种子载波间隔的频域资源,也可以是包含多种子载波间隔的频域资源,也就是说网络设备既可以为终端设备分配一种子载波间隔的频域资源,也可以为终端设备分配多种子载波间隔不同的频域资源。
当上述目标频域资源包含多种子载波间隔的频域资源时,第一指示信息指示的是该多种子载波间隔的频域资源所处的资源区域。
本申请实施例中,第一指示信息采用的指示单位即第一单元的大小是大于目标频域资源的最小频域调度单元的,而现有技术在指示频域资源时采用的指示单位的大小是与频域资源的最小频域调度单元相同的,与现有技术相比,本申请实施例是采用较大的指示单元对频域资源进行指示,因此能够节省信令开销。
可选地,当上述资源区域包含目标频域资源时,图3的方法还包括:
终端设备接收网络设备发送的第二指示信息,第二指示信息以第二单元为粒度指示资源区域中的每个子区域中的频域资源是否属于目标频域资源, 其中,每个子区域的大小与第二单元的大小相同,第二单元的大小与目标频域资源的最小频域调度单元相同。
本申请实施例中,通过第一指示信息的粗指示能够在系统频域资源上指示出目标频域资源所处的资源区域,而通过第二指示信息的细指示能够指示资源区域中的每个子区域中的频域资源是否属于目标频域资源,从而能够确定目标频域资源的在系统频域资源中的位置。并且,与现有技术中直接采用频域资源的最小频域调度单元为粒度来指示的方式相比,能够节省一定的信令开销。
可选地,上述第一指示信息和第二指示信息可以为比特图信息。具体地,当上述第一指示信息的比特位的取值为1时表示资源区域中包含目标频域资源,而当上述第一指示信息的比特位的取值为0时表示资源区域中不包含目标频域资源。当然,还可以采用别的比特位取值来表示资源区域中是否包含目标频域资源。
可选地,当上述资源区域包含目标频域资源时,该资源区域可以包括多个子区域,上述第二指示信息可以包含多个比特位,该多个比特位中的每个比特位分别对应多个子区域中的一个子区域,当第二指示信息中的第一比特位为第一取值时,与该第一比特位对应的子区域包含的频域资源属于该目标频域资源,其中,所述第一比特位为所述多个比特位中的任意一个。也就是说第二指示信息的每个比特位指示一个区域中的频域资源是否属于目标频域资源。
例如,当上述资源区域包含两个子区域时,第二指示信息一共包含两个比特位,当这两个比特位的取值为10时表示仅第一个子区域中的频域资源属于目标频域资源,当这两个比特位的取值为01时表示仅第二个子区域中的频域资源属于目标频域资源,当这两个比特位的取值为11时表示第一个子区域和第二个子区域中的频域资源均属于目标频域资源。
可选地,上述目标频域资源可以是第一频域资源,也就是说目标频域资源可以只包含一种子载波间隔的频域资源。
下面以图4为例,详细说明网络设备如何通过第一指示信息和第二指示信息指示第一频域资源。
在图4中,整个系统频域资源中包含第一频域资源和第二频域资源,其中,第一频域资源是网络设备分配给终端设备的频域资源。第一频域资源和 第二频域资源的子载波间隔分别为f1和f2,组成第一频域资源和第二频域资源的最小频域资源单元为R1和R2,并且f2=2f1,R2=2R1。网络设备先以第一指示信息指示包含第一频域资源的第一区域(该第一区域的大小与R1的大小相同),该第一区域为第一指示信息的比特位取值为1的所对应的区域。通过第一指示信息指示出了第一频域资源所在的第一区域,但是第一区域中的各个子区域中的频域资源并不一定全部属于第一频域资源,这时就通过第二指示信息来具体指示第一频域资源在第一区域的分布情况。第一区域对应第二指示信息的两个比特位,也就是说第一区域包含两个子区域,每个子区域的大小与R2相同。当第二指示信息的比特位取值为10时表示仅第一个子区域中的频域资源属于第一频域资源,当第二指示信息的比特位的取值为01时表示仅第二个子区域中的频域资源属于第一频域资源,当第二指示信息的比特位的取值为11时表示第一个子区域和第二个子区域中的频域资源均属于第一频域资源。
由图4可以得知,第二指示信息只需要在第一指示信息指示的存在第一频域资源的第一区域进行指示即可,也就是说,第二指示信息只需要在第一指示信息为1的对应区域进行指示即可,在其它的资源区域不用指示,因此,与现有的指示频域资源的方式相比,能够节省大量的比特位,进而减少信令开销。
具体地,以图2和图4中同样指示第一频域资源为例,在图2中需要发送包含字段10000100000010000000(共20位)的第一指示信息,而在图4中仅需要发送包含字段1010001000(共10位)的第一指示信息和包含字段100110(共6位)的第二指示信息,在图2中第一指示信息共占用的比特位为20位,而在图4中第一指示信息和第二指示信息共占用的比特位为16位,因此,图4的资源指示方式与图2中的资源指示方式相比能够节省一定的信令开销。如果进一步考虑到第一频域资源只会占用整个系统频域资源的很小一部分,那么图4中的指示信息占用的比特位会远小于图2中的指示信息占用的比特位。
可选地,当上述目标频域资源包括第一频域资源和第二频域资源时,第一频域资源的子载波间隔小于第二频域资源的子载波间隔,第一指示信息用于以第一单元指示系统频域资源中的资源区域是否包含第一频域资源和第二频域资源,第二子载波间隔大于或者等于第二频域资源的子载波间隔。
应理解,当目标频域资源仅包含一种频域资源时,第二子载波间隔可以大于目标频域资源的子载波间隔,当目标频域资源包含多种频域资源时,第二子载波间隔可以大于等于目标频域资源中子载波间隔较大的一种频域资源的子载波间隔,优选地,第二子载波间隔大于等于目标频域资源中子载波间隔最大的频域资源的子载波间隔。
另外,目标频域资源包括第一频域资源和第二频域资源可以是指目标频域资源由这两种频域资源组成,也可以是指除了这两种频域资源之外,目标频域资源还包括其它种类的频域资源。
可选地,当上述资源区域包含第一频域资源和第二频域资源时,图3的方法还包括:终端设备接收网络设备发送的第二指示信息,第二指示信息以上第二单元为粒度指示资源区域的每个子区域中的频域资源是否属于第一频域资源或者第二频域资源,每个子区域的大小与第二单元的大小相同,第二单元的大小与第一频域资源的最小频域调度单元相同。
在通过第一指示信息指示出包含第一频域资源或第二频域资源的资源区域后,接下来只需要在需要指示该资源区域中的每个子区域中的资源属于第一频域资源还是第二频域资源,而不用在不包含第一频域资源或第二频域资源的资源区域中进行指示,能够节省大量的信令开销。
可选地,上述第一指示信息和第二指示信息具体可以是比特图信息。
可选地,当上述资源区域中包含第一频域资源或者第二频域资源时,并且第二指示信息中的比特位全为第二取值时,该资源区域中的所有子区域中的频域资源均属于第二频域资源;当第二指示信息中的比特位不全为第二取值时,资源区域中的至少一个子区域中的频域资源属于所述第一频域资源。可选地,上述第二取值可以为0。当然,该第二取值也可以为其它的值。
下面结合图5对目标资源由第一频域资源和第二频域资源组成时,第一指示信息和第二指示信息如何指示第一频域资源和第二频域资源进行详细的说明。
如图5所示,网络设备同时为终端设备分配了第一频域资源和第二频域资源,第一频域资源和第二频域资源的子载波间隔分别为f1和f2,组成第一频域资源和第二频域资源的最小频域资源单元为R1和R2,并且f2=2f1,R2=2R1。网络设备以第一指示信息指示包含第一频域资源或第二频域资源的资源区域,然后以第二指示信息具体指示第一频域资源或者第二频域资源 在资源区域中的具体分布情况。
在图5中,网络设备先以R2为单位将系统频域资源划分成多个资源区域,只要该资源区域中有第一频域资源或者第二频域资源,那么第一指示信息的字段的比特位的取值就为1,接下来再通过第二指示信息在包含第一频域资源或者第二频域资源的资源区域中指示这两种资源的分布情况。具体地,假设第二区域(第二区域由两个子区域组成)中包含第一频域资源或者第二频域资源,那么,当第二指示信息的比特位取值为10时表示第一个子区域中的频域资源属于第一频域资源,当第二指示信息的比特位的取值为01时表示第二个子区域中的频域资源属于第一频域资源,当第二指示信息的比特位的取值为11时表示两个子区域中的全部频域资源均属于第一频域资源,当第二指示信息的比特位的取值为00时表示两个子区域中的全部频域资源均属于第二频域资源。
以图2和图5中同样指示第一频域资源和第二频域资源为例,在图2中需要发送包含字段010010010(共10位)的第二指示信息,以及包含字段10000100000010000000(共20位)的第一指示信息。在图5中需要发送包含字段1110101010(共10位)的第一指示信息和包含字段100001001000(共12位)的第二指示信息。图2中为了指示第一频域资源和第二频域资源需要30比特的字段,而在图5中为了指示第一频域资源和第二频域资源仅需要22比特的字段,由此可见,当同时指示多种具有不同子载波间隔的频域资源时,本申请实施例的频域资源指示方法能够节省较多的信令开销。
如图6所示,网络设备为终端设备分配了第一频域资源,第一频域资源的最小频域调度单元为R1,网络设备以R2(R2=2R1)为基本单位将整个系统频域资源划分成多个资源区域,并以R2为粒度指示第一频域资源在系统频域资源中的位置,由于第一频域资源是以连续两个R1大小资源块在系统资源中离散分布,因此,当通过第一指示信息指示包含第一频域资源的资源区域后,第二指示信息仅需要采用取值为1(或0)的比特位去指示包含第一频域资源的资源区域中的频域资源均属于第一频域资源即可,图6与图5和图4的情况相比,能够更多的信令开销。
可选地,图3的方法还可以包括:终端设备接收网络设备发送的资源种类信息;终端设备根据资源种类信息确定目标频域资源包含的频域资源的种类。例如,当网络设备为终端设备分配两种子载波间隔的频域资源时(子载 波间隔分别是f1和f2,组成这两种频域资源的最小频域调度单元为R1和R2),那么资源指示信息可以指示这两种频域资源的子载波间隔分别是f1和f2,也可以指示这两种频域资源的最小频域调度单元分别为R1和R2。
可选地,当目标频域资源包含多种类型的频域资源时,上述资源种类信息可以由多个指示信息组成,每个指示信息用于指示一种频域资源的类型。资源种类信息也可以仅有一个指示信息组成,这时该指示信息同时指示目标频域资源中包含的多种频域资源的类型。
图7是本申请实施例的指示频域资源的方法的示意性流程图。图7的方法包括:
710、终端设备接收网络设备发送的资源位置指示信息;
720、终端设备接收终端设备发送的资源类别指示信息;
730、终端设备根据资源位置指示信息确定目标频域资源在系统频域资源中所处的位置,其中,目标频域资源为网络设备从多种频域资源中为终端设备分配的频域资源,不同种类的频域资源的子载波间隔不同;
740、终端设备根据资源类别指示信息确定目标频域资源包含的频域资源的种类。
本申请实施例中,网络设备通过资源类别指示信息能够指示为终端设备分配的频域资源的资源种类,可以实现对多种子载波间隔的频域资源的指示。
可选地,当上述目标频域资源包括M种频域资源时,上述资源位置指示信息可以包括M个位置指示信息,该M个位置指示信息依次指示M种频域资源在系统频域资源中所处的位置,该资源种类指示信息可以包括M个种类指示信息,该M个种类指示信息依次指示该M种频域资源的资源种类,M为大于等于1的整数。应理解,当目标频域资源包括M种频域资源时,上述资源种类指示信息也可以仅有一个指示信息组成,这时该资源种类信息仅用一个指示信息指示M种频域资源的种类。
例如,如图8所示,当网络设备为终端设备分配子载波间隔分别为f1和f2的频域资源时,上述资源种类信息可以仅由一个指示字段组成,这时该指示字段同时指示这两种频域资源的种类,另外,上述资源种类信息也可以由两个字段组成,这两个字段分别指示子载波间隔为f1和f2的频域资源的资源种类。
上文结合图3至图8从网络设备的角度对本申请实施例的指示频域资源的方法进行了详细的描述,下面结合图9和图10从终端设备的角度对本申请实施例的指示频域资源的方法进行描述。应理解,图9和图10中描述的方法的步骤是与图3至图8中描述的方法是对应的,为了简洁,适当省略重复的描述。

本申请实施例中,第一指示信息采用的指示单位即第一单元的大小是大于目标频域资源的最小频域调度单元的,而现有技术在指示频域资源时采用的指示单位的大小是与频域资源的最小频域调度单元相同的,因此,与现有技术相比,本申请实施例能够节省信令开销。
