Description

一种资源指示方法、设备和计算机存储介质 技术领域
本发明涉及无线通信技术,具体涉及一种资源指示方法、设备和计算机存储介质。
背景技术
现有的长期演进(LTE,Long Term Evolution)系统中,可基于比特图(bitmap)指示资源分配,如图1所示,例如,bitmap中的一个比特(bit)指示一个资源块组(RBG)是否被分配给某个终端,1表示分配给该终端,0表示不分配给该终端。而RBG包含的资源块(RB)的数量,即RBG大小与系统带宽有关。
在5G系统中,终端的操作带宽可能小于系统带宽,可称为带宽分段(bandwidth part)。RBG大小和数量不根据系统带宽变化,而是根据终端采用的bandwidth part确定的。由于bitmap包含的bit数是固定的,而终端采用不同的bandwidth part则可能对应不同的RBG大小,从而会导致实际使用的bitmap的bit数量往往达不到最大的数量,对于没有使用的bit只能用0填充。这种方式会造成控制信令开销的浪费,并限制了调度的灵活性。

具体实施方式
下面结合附图及具体实施例对本发明作进一步详细的说明。
实施例一
本发明实施例提供了一种资源指示方法。图2为本发明实施例一的资源指示方法的流程示意图;如图2所示,所述方法包括:
步骤101:第一设备向第二设备发送第一比特图,所述第一比特图用于指示所述第一设备和所述第二设备之间数据或信令传输的频域资源;所述第一比特图对应于至少两种资源块组大小。
本实施例中,所述第一设备为网络设备或终端设备,所述第二设备为终端设备。
本实施例中,所述资源块组大小表示该资源块组包含的物理资源块 (PRB,Physical Resource Block)数量,例如,资源块组大小(即包含的PRB数量)可以为1、2、4、8、16…。

作为一种实施方式,所述第一种资源块组大小大于所述第二种资源块组大小。所述第一比特图用于在包括N个资源块的带宽中指示频域资源,N可表示带宽分段大小,该带宽分段大小与资源块组的大小相关。则所述第一部分比特和所述第二部分比特满足:

或者,N=B1×P1+B2×P2-NΔ            (2)
其中,B1表示所述第一部分比特的数量,B2表示所述第二部分比特的数量,B1和B2的总和等于所述第一数量;P1表示第一种资源块组大小,P2表示第二种资源块组大小,NΔ小于P2。
上述表达式(1)表示第一比特图中的所有比特均被配置用于资源指示,不存在比特的浪费。上述表达式(2)表示第一比特图中存在NΔ数量的比特未被配置用于资源指示,但NΔ小于相对较小的第二种资源块组大小,NΔ数量的比特用0填充。
作为一种实施方式,所述第一种资源块组大小为所述第二种资源块组大小的两倍,从资源块组大小(即包含的PRB数量)可以为1、2、4、8、16…的列举可以看出,所述第一种资源块组大小和所述第二种资源块组大小为相邻的两组资源块组大小。则所述第二部分比特和所述第一部分比特满足:
B1=B-B2;
其中,B1表示所述第一部分比特的数量,B2表示所述第二部分比特的数量,B为所述第一数量;P2表示第二种资源块组大小;
Figure PCTCN2017101656-appb-000002
表示向上取整。
采用本发明实施例的技术方案,通过对应于至少两种资源块组大小的第一比特图的资源指示,在保持比特图长度不变的条件下,减少了比特图中未被使用的比特数量,避免部分比特无法被使用,从而最大限度的使用比特图中的比特位,通过选取最佳的调度颗粒度组合,使用各种带宽的资源调度,大大减少了控制信令开销的浪费,也提升了调度的灵活性。

本实施例中,所述第二设备为终端设备,所述第一设备为网络设备或终端设备。
本实施例中,所述第一比特图用于在包括N个资源块的带宽中指示频域资源,N可表示带宽分段大小,该带宽分段大小与资源块组的大小相关。
作为一种实施方式,图4为本发明实施例二的资源指示方法的另一种流程示意图;如图4所示,步骤202具体可包括:
步骤2021:所述第二设备确定分布规则,基于所述分布规则确定所述至少两种资源块组大小中每种资源块组大小对应于所述第一比特图中的位置或位置范围。
步骤2022:所述第二设备基于确定的每种资源块大小对应于所述第一比特图中的位置或位置范围传输数据或信令。
本实施例中,所述分布规则表示至少两组资源块组大小在所述第一比特图中的分布情况,具体用于指示所述至少两种资源块组大小中任一组资源块组大小对应于所述第一比特图的长度中的包括的至少两个位置范围中的一个位置范围,或者特定比特位置;所述终端可基于每种资源块组大小在所述第一比特图中的分布情况传输数据或信令。实际应用中,可将所述第一比特图的长度划分为至少两个位置范围,每种资源块组大小可对应于所述至少两个位置范围中的其中一个位置范围。例如,将第一比特图的长度划分为三个位置范围,该三个位置范围包括:第1个比特-第a个比特、第a+1个比特-第b个比特、第b+1个比特-第c个比特,a小于b小于c,可以理解为,将所述第一比特图划分为低位范围、中间范围或高位范围,则所述每种资源块组大小可对应于低位范围、中间范围或高位范围。作为另一种实施方式,所述每种资源块组大小也可对应于指定比特位置,
作为第一种实施方式,所述第二设备确定分布规则,包括:所述第二设备将预定义的分布规则确定为所述分布规则。具体的,所述第二设备中可预先定义分布规则,基于该分布规则确定所述至少两种资源块组大小中每种资源块组大小对应于所述第一比特图中的位置或位置范围。
作为第二种实施方式,所述第二设备确定分布规则,包括:所述第二设备接收第一信令,基于所述第一信令的指示确定所述分布规则。其中,所述第一信令为RRC控制信令或系统信令,则所述第二设备可基于RRC控制信令或系统信令的指示确定分布规则。
作为第三种实施方式,所述第二设备确定分布规则,包括:所述第二设备接收第一信令,基于所述第一信令的指示确定至少两种候选分布规则;所述第二设备接收第二信令,基于所述第二信令的指示在所述至少两种候选分布规则中确定一种分布规则作为所述分布规则。其中,所述第一信令为RRC控制信令或系统信令,所述第二信令为下行链路控制信息或MAC  CE信息。
具体的,第二设备可基于RRC控制信令或系统信令的指示确定至少两种候选分布规则,再基于下行链路控制信息或MAC CE信息从所述至少两种候选分布规则中选择一个分布规则,基于该分布规则确定所述至少两种资源块组大小中每种资源块组大小对应于所述第一比特图中的位置或位置范围。
采用本发明实施例的技术方案,通过对应于至少两种资源块组大小的第一比特图的资源指示,在保持比特图长度不变的条件下,减少了比特图中未被使用的比特数量,避免部分比特无法被使用,从而最大限度的使用比特图中的比特位,通过选取最佳的调度颗粒度组合,使用各种带宽的资源调度,大大减少了控制信令开销的浪费,也提升了调度的灵活性。
下面结合具体的应用场景对本发明实施例的资源指示方法进行详细说明。
场景一
本场景中以bitmap尺寸为25bit为例。
针对不同的带宽分段大小N(即bitmap用于在包括N个资源块的带宽中指示频域资源)采用两种资源块组大小在组合,其中,第一种资源块组大小记为P1,对应的第一部分比特记为B1,第二种资源块组大小记为P2,对应的第二部分比特记为B2。则N能被P2整除的情况如表1所示,即满足B=B1+B2且N=B1×P1+B2×P2。

N不能被P2整除的情况如表2所示,即满足B=B1+B2且N=B1×P1+B2×P2-NΔ
Figure PCTCN2017101656-appb-000005
表2
而现有方案中采用对应于一种资源块组大小的比特图可参照表3所示,对比表3、表1和表2,采用现有方案相比于本发明实施例的资源指示方案,现有方案浪费的bit数均在5bit和10bit左右,而采用本发明实施例的资源指示方案,浪费的bit数最大为4bit。

场景二
针对一种带宽分段大小,采用两种资源块组大小在组合,其中,第一种资源块组大小记为P1,对应的第一部分比特记为B1,第二种资源块组大小记为P2,对应的第二部分比特记为B2。在本场景中,P1大于P2,则分布规则为:具有较大尺寸的第一种资源块组大小P1分布在带宽分段的低位范围,具有较小尺寸的第二种资源块组大小P2分布在带宽分段的高位范围, 如图5a所示。
场景三
针对一种带宽分段大小,采用两种资源块组大小在组合,其中,第一种资源块组大小记为P1,对应的第一部分比特记为B1,第二种资源块组大小记为P2,对应的第二部分比特记为B2。在本场景中,P1大于P2,则分布规则为:具有较大尺寸的第一种资源块组大小P1分布在带宽分段的高位范围,具有较小尺寸的第二种资源块组大小P2分布在带宽分段的低位范围,如图5b所示。
场景四
针对一种带宽分段大小,采用两种资源块组大小在组合,其中,第一种资源块组大小记为P1,对应的第一部分比特记为B1,第二种资源块组大小记为P2,对应的第二部分比特记为B2。在本场景中,P1大于P2,则分布规则为:具有较大尺寸的第一种资源块组大小P1分布在带宽分段的高位范围和低位范围,具有较小尺寸的第二种资源块组大小P2分布在带宽分段的中间范围,如图5c示。其中,具有较小尺寸的第二种资源块组大小P2分布在带宽分段中部的具体位置,可由第一信令配置,所述第一信令具体可以为RRC控制信令或系统信令。
场景五
与场景四相反,针对一种带宽分段大小,采用两种资源块组大小在组合,其中,第一种资源块组大小记为P1,对应的第一部分比特记为B1,第二种资源块组大小记为P2,对应的第二部分比特记为B2。在本场景中,P1大于P2,则分布规则为:具有较大尺寸的第一种资源块组大小P1分布在带宽分段的中间范围,具有较小尺寸的第二种资源块组大小P2分布在带宽分段的高位范围和低位范围,如图5d示。其中,具有较大尺寸的第二种资源块组大小P1分布在带宽分段中部的具体位置,可由第一信令配置,所述第 一信令具体可以为RRC控制信令或系统信令。
基于上述场景二至场景五,实际应用中,作为终端设备的第二设备可基于第一信令将满足上述场景二至场景五的分布规则确定为候选分布规则;进一步基于第二信令从候选分布规则中选择其中一种分布规则。
