为了便于理解本申请实施例,下面对本申请实施例所涉及到的基本流程以及基本概念进行简单说明。应理解,下文所介绍的基本流程以及基本概念并不对本申请实施例产生限定。
5G的主要应用场景为:增强移动超宽带(eMBB,Enhanced Mobile Broadband)、低时延高可靠通信(URLLC,Ultra Reliable Low Latency Communications)、大规模机器类通信(mMTC,massive Machine Type Communications)。其中,eMBB以用户获得多媒体内容、服务和数据为目标,其需求增长十分迅速;由于eMBB可能部署在不同的场景中,便如室内,市区,农村等,其能力和需求的差别也比较大,所以必须结合具体的部署场景详细分析。URLLC的典型应用包括:工业自动化,电力自动化,远程医疗操作(手术),交通安全保障等。mMTC的典型特点包括:高连接密度、小数据量、时延不敏感业务、低成本和长使用寿命等。
在5G网络环境中,为了降低空口信令和快速恢复无线连接,快速恢复数据业务的目的,定义了新的RRC(无线资源控制,Radio Resource Control)状态,即RRC_INACTIVE(RRC非激活)状态。这种状态有别于RRC_IDLE(RRC空闲)状态、RRC_ACTIVE(RRC激活)或RRC_CONNECTED(RRC连接)状态,分别来说:
RRC_IDLE状态:移动性为基于UE的小区选择重选,寻呼由核心网(CN,Core Network)发起以及寻呼区域由CN配置。相应的,基站侧不存在UE接入层(AS,Access Stratum)上下文且不存在RRC连接。
RRC_CONNECTED状态:UE与基站侧存在RRC连接,基站和UE存在UE AS上下文。网络侧获取到的UE的位置是小区级别的;移动性是网络侧控制的。并且所述UE和基站之间可以传输单播数据。
RRC_INACTIVE状态:移动性为基于UE的小区选择重选,存在CN-NR(New Radio,新无线)之间的连接;UE AS上下文存在某个基站上,寻呼由无线接入网(RAN,Radio Access Network)触发,基于RAN的寻呼区域由RAN管理,网络侧知道UE的位置是基于RAN的寻呼区域级别的。
NR频域资源分配,具体包括:
NR上行/下行均支持两种频域资源分配类型:Type 0频域资源分配类型和Type 1频域资源分配类型,网络侧通过高层参数resourceAllocation来配置终端所使用的频域资源分配的类型,可以配置为终端使用资源分配Type0、资源分配Type 1,或者dynamic switch,当配置参数为“dynamicswitch”时,网络侧通过DCI中的Frequency domain resource assignment域来指示终端所使用的频域资源分配的类型。
如果在scheduling DCI中没有配置BWP indicator指示域,或者终端不支持基于DCI的BWP change,那么Type0和Type1的RB indexing是在终端的active BWP中确定的;如果终端支持基于DCI的BWP change,且scheduling DCI中配置了BWP指示域,那么频域资源分配Type 0和资源分配Type 1的RB indexing是基于DCI中的BWP indicator指示的BWP确定的。终端需要先通过PDCCH检测确定BWP,再确定在BWP中的频域资源分配。
Type 0,具体包括:如图2上所示,Type 0频域资源分配类型的粒度为RBG,RBG为一系列连续的虚拟RB的组合,每个RBG包括的虚拟RB的数量根据BWP的大小以及RRC配置参数rbg-Size确定,rbg-Size用于配置下表1中的‘configuration 1’(配置1)或者‘configuration 2’(配置2),另外,在下表中“Bandwidth Part Size”表示带宽部分BWP的大小,也就是说,在确定了BWP的大小之后基于表1可以确定在配置1或配置2下的RBG的大小:
Bandwidth Part Size configuration 1(配置1) configuration 2(配置2)
1-36 2 4
37-72 4 8
73-144 8 16
145-275 16 16
表1
Type 0频域资源分配类型,采用一个bitmap指示分配给终端的RBG,1代表将这个RBG分配给终端,0代表不将这个RBG分配给终端,可以实现频域资源在BWP内的灵活分布,支持不连续资源分配,可以用离散的频域传输对抗频率选择型衰落。但缺点是:(1)bitmap的比特数量较大,需要覆盖整个BWP中的每个RBG;(2)资源分配颗粒度较粗,因为一个RBG包含2~16个RB,并不能逐RB的选择资源;
对于一个包含
Figure PCTCN2021144065-appb-000001
个PRB的BWP,其包含的总的RBG的数量N RBG为:
Figure PCTCN2021144065-appb-000002
其中:
第一个RBG的大小为
Figure PCTCN2021144065-appb-000003
最后一个RBG的大小为:
Figure PCTCN2021144065-appb-000004
如果
Figure PCTCN2021144065-appb-000005
且P为其他值。
其余的RBG的大小为P。
Type 1资源分配类型,如图2下所示,Type 1资源分配类型可以指示给终端一系列连续的虚拟RB,采用一个RIV(resource indication value,资源指示值)对所分配的起始RB(RB start)和RB数量(L RBs)进行联合编码。Type 1的优点是可以用较少的比特数量指示RB级别的资源,但缺点只能分配连续的频域资源,当资源数量较少时,频率分集有限,容易受到频率选择型衰落的影响。
起始RB(RB start)和RB数量(L RBs)联合编码的方式如下:
如果

Figure PCTCN2021144065-appb-000007
否则,
Figure PCTCN2021144065-appb-000008
其中,L RBs≥1并且不超过
Figure PCTCN2021144065-appb-000009
其中,L RBs表示RB数量,RB start表示起始RB的编号;
Figure PCTCN2021144065-appb-000010
表示BWP的大小;
Figure PCTCN2021144065-appb-000011
表示向下取整。
NR支持终端在网络侧配置的search space sets(搜索空间集合)中进行PDCCH盲检,之所以是“盲检”,即终端在检测到PDCCH承载的DCI之前并不知道DCI的format等信息,因此需要使用一些固定的DCI size对搜索空间集合中的PDCCH candidate进行盲检。为了降低终端盲检PDCCH的复杂度,NR规定在进行完协议定义的DCI size alignment步骤后,终端不期待总的DCI size数大于4,以及C-RNTI加扰的总的DCI size数大于3。
由于终端只是尝试使用一些固定的DCI size来对PDCCH进行检测,这就需要终端在PDCCH盲检之前,知道不同DCI format的DCI size是多少,换句话说,也就是需要知道DCI中所包含的每个信息域所包含的比特数是多少,以频域资源分配指示Frequency domain resource assignment(FDRA)域为例,其比特数的确定方式如下:
如果只配置了资源分配type 0,则指示域包含N RBG比特;
如果只配置了资源分配type 1,则指示域包含
Figure PCTCN2021144065-appb-000012
比特;
如果同时配置了type 0和type 1,则指示域包含
Figure PCTCN2021144065-appb-000013
比特,其中最高位比特用于指示终端使用的资源分配类型,0表示type 0,1表示type 1。其中,
Figure PCTCN2021144065-appb-000014
表示BWP的大小,
Figure PCTCN2021144065-appb-000015
表示向上取整;N RBG表示资源分配type 0中FDRA指示域中包含的指示信息的比特数;max()表示取最大值。
DCI format 1_1/0_1中包含的其他和高层配置参数或者BWP size相关的指示域(以TDRA为例,也包含其他的,不一一列举):
-Time domain resource assignment(TDRA):NR时域资源分配为网络侧先通过RRC参数pdsch-TimeDomainAllocationList为终端配置多个TDRA entry,每个TDRA entry包含DCI到PDSCH/PUSCH的slot offset、PDSCH/PUSCH所占的符号、PDSCH/PUSCH的mapping type等,再通过DCI中的TDRA field指示其中的一个TDRA entry;
DCI中的TDRA field包含

比特,其中I为高层配置的pdsch-TimeDomainAllocationList所包含的TDRA entry(条目)数目,或者缺省TDRA table所包含的entry数。

S310、终端设备接收网络设备发送的第一下行控制信息(DCI,Downlink Control Information);
其中,所述第一DCI用于调度N个第一服务小区的N个数据信道;所述第一DCI中包含频域资源分配指示(FDRA,Frequency domain resource assignment)域,所述FDRA域所指示的频域大小由M个第二服务小区的激活BWP确定;所述M个第二服务小区的激活BWP总和大于等于所述N个第一服务小区的激活BWP总和;M为正整数,N为正整数。
所述M个第二服务小区,可以是由高层信令配置,和/或按照规则确定的。
所述M个第二服务小区包括以下至少之一:
同小区组的服务小区;
在同一小区调度的服务小区;
高层信令配置的服务小区中的至少部分服务小区;
第一服务小区组合中的服务小区;所述第一服务小区组合中的服务小区为高层信令配置的,且所述第一服务小区组合为等效激活BWP的总和最大的服务小区组合;
激活的服务小区中的至少部分激活的服务小区;
第二服务小区组合中的服务小区;所述第二服务小区组合中的服务小区为激活的服务小区,且所述 第二服务小区组合为等效激活BWP的总和最大的服务小区组合。
具体的,所述同小区组的服务小区,可以指的是同一个小区组的全部服务小区。关于小区组可以为网络设备通过高层信令为所述终端设备配置的,比如,网络侧通过高层信令为终端设备配置4个服务小区(cell 1~cell 4),并配置所述4个服务小区属于相同的cell group(小区组),如都属于MCG(Master Cell group,主小区组),或者都属于primary PUCCH group(主PUCCH组)/SCG(Secondary Cell group,辅小区组)。此时,上述4个服务小区(cell 1~cell 4)可以为M个第二服务小区。
所述在同一小区调度的服务小区,可以是:在一个服务小区传输的所述第一DCI能够调度的服务小区。
比如,所述网络设备可以为所述终端设备配置服务小区之间的调度关系。参见图4来说,网络侧通过高层信令为终端设备配置4个服务小区,分别为cell 1~cell 4;其中,cell 1可以和cell 2一起调度,或cell1可以和cell 3一起被调度,或者,cell 2可以和cell 3一起被cell 1调度。此时,同一小区调度的服务小区可以指的是cell2和cell3,或者,cell1和cell2,或者cell1和cell3。则在cell 1传输的第一DCI,可以是用于调度cell1~cell3的任意组合中包含的服务小区,则该cell 1、cell2和cell3中的任意组合为cell1这个小区能够调度的M个第二服务小区。
进一步地,所述同一小区调度的服务小区为:所述同一小区的同一个搜索空间的物理下行数据信道(PDCCH,Physical Downlink Control Channel)调度的服务小区。也就是说,所述M个第二服务小区为某一个小区在同一个搜索空间(search space)的PDCCH调度的全部服务小区。
高层信令配置的服务小区中的至少部分服务小区,具体可以指的是:网络设备通过高层信令为终端设备配置的全部服务小区中的子集或全集。举例来说,网络侧通过高层信令为终端设备配置4个服务小区,分别为cell 1~cell 4,可以将上述cell1~cell4作为前述M个第二服务小区;或者,将cell1和cell2作为前述M个第二服务小区等等,这里不做穷举。
第一服务小区组合中的服务小区;所述第一服务小区组合中的服务小区为高层信令配置的,且所述第一服务小区组合为等效激活BWP的总和最大的服务小区组合,其确定方式可以是:将网络设备通过高层信令为终端设备配置的全部服务小区分别进行组合,得到多个服务小区组合;计算所述多个服务小区组合的等效激活BWP的总和,将等效激活BWP的总和最大的一个服务小区组合作为第一服务小区组合,该第一服务小区组合中的全部服务小区作为前述M个第二服务小区。
激活的服务小区中的至少部分激活的服务小区,可以为:激活的所有服务小区任意组合的子集或全集。举例来说,当前激活的服务小区有3个服务小区,分别为cell 1~cell 3,可以将上述cell1~cell3作为前述M个第二服务小区;或者,将cell1和cell2作为前述M个第二服务小区等等,这里不做穷举。
上述第二服务小区组合中的服务小区;所述第二服务小区组合中的服务小区为激活的服务小区,且所述第二服务小区组合为等效激活BWP的总和最大的服务小区组合,其确定方式可以是:将当前激活的全部服务小区分别进行组合,得到多个服务小区组合;计算所述多个服务小区组合的等效激活BWP的总和,将等效激活BWP的总和最大的一个服务小区组合作为第二服务小区组合,将该第二服务小区组合中的全部服务小区作为前述M个第二服务小区。
其中,所述等效激活BWP的总和,指的是:每个服务小区组中全部服务小区的激活BWP的总和。
在前述基础上,一种实施方式中,所述M个第二服务小区中包含目标小区;所述目标小区为所述第一DCI调度的小区。也就是说,在原处理机制中,网络设备通过DCI调度cell 1;在本公开提供的实施方式中,上述M个第二服务小区包含上述cell 1。
其中,所述N个第一服务小区可以为一个或多个,具体与当前所要调度的服务小区的数量相关。
所述N个第一服务小区中每个第一服务小区对应一个数据信道,即所述N个第一服务小区与所述N个数据信道为一一对应的关系。
上述数据信道具体可以包括:PDSCH(物理下行共享信道,Physical Downlink Share CHannel)或者PUSCH(物理上行共享信道,Physical Uplink Share CHannel)。
所述N个第一服务小区由以下之一指示:高层信令,所述第一DCI,第二DCI;所述第二DCI与所述第一DCI不同。
也就是说,上述N个第一服务小区由高层信令配置,或者由所述第一DCI指示,或者由其他DCI指示。应理解,所述第一DCI指的为包含FDRA域的DCI,而所述网络设备可以为终端设备下发的还有其他DCI,本公开实施例中将其他DCI中任意之一称为第二DCI。
所述N个第一服务小区可以为M个第二服务小区的子集或全集,且所述N个第一服务小区的激活BWP总和小于或等于所述M个第二服务小区的激活BWP总和。比如,所述网络设备可以预先通过高层信令为终端设备发送配置的M个第二服务小区;然后网络设备再通过第一DCI(或第二DCI,或高层信令)为终端设备配置M个第二服务小区中的N个第一服务小区。又比如,所述终端设备按照规则 确定M个第二服务小区;然后网络设备再通过第一DCI(或第二DCI,或高层信令)为终端设备配置M个第二服务小区中的N个第一服务小区。
或者,所述N个第一服务小区与所述M个第二服务小区不同,且所述N个第一服务小区的激活BWP总和小于或等于所述M个第二服务小区的激活BWP总和。举例来说,所述M个第二服务小区可以为系统中的部分服务小区,比如服务小区1-5,其激活BWP总和为200PRB;N个第一服务小区可以为服务小区7和服务小区8,其激活BWP总和为100PRB。
或者,所述N个第一服务小区与所述M个第二服务小区存在交集,且所述N个第一服务小区的激活BWP总和小于或等于所述M个第二服务小区的激活BWP总和。举例来说,所述M个第二服务小区可以为系统中的部分服务小区,比如服务小区1-5,其激活BWP总和为200PRB;N个第一服务小区可以为服务小区3和服务小区8,其激活BWP总和为150PRB。
上述N个第一服务小区为所述M个第二服务小区的子集或全集,也就是说,N个第一服务小区可以等于M个第二服务小区,比如,M个第二服务小区包含Cell 1~cell 4,则N个第一服务小区中也包含cell 1-cell 4。或者,N个第一服务小区为M个第二服务小区的一部分,比如,M个第二服务小区包含Cell 1~cell 4,则N个第一服务小区包含cell 1、cell 2。
在前述基础上,一种实施方式中,所述N个第一服务小区中包含目标小区;所述目标小区为所述第一DCI调度的小区。也就是说,在原处理机制中,网络设备通过DCI调度cell 1;在本公开提供的实施方式中,上述N个第一服务小区中包含cell 1。
所述FDRA域的大小由第一BWP的大小确定;其中,所述第一BWP的大小为以下之一:
M个第二服务小区的激活BWP的频域资源总和;
M个第二服务小区的激活BWP的频域资源的平均值。
所述第一BWP的大小即所述FDRA域所能够指示的最大频域范围,或者所述第一BWP的大小为所述FDRA域所指示的频域大小。也就是说,终端设备可以基于第一BWP来确定在所述第一DCI中包含的FDRA域的大小;其中FDRA域的大小具体可以指的是,所述FDRA域占用的bit位数。
其中,所述M个第二服务小区的激活BWP的频域资源总和具体可以指的是:M个第二服务小区中每个第二服务小区的激活BWP的频域资源相加得到的总和。
再进一步地,由于上述M个第二服务小区可能存在前述多种情况,相应的,所述M个第二服务小区的激活BWP的频域资源总和,可以是任意一种情况下M个第二服务小区中每个服务小区的激活BWP的频域资源相加得到的总和。
M个第二服务小区的激活BWP的频域资源的平均值的确定方式可以为:M个第二服务小区的激活BWP的频域资源相加得到总和,将该总和除以M得到平均值。
另外,所述第一BWP的大小还可以为网络设备配置的数值。比如,可以是网络设备通过高层信令配置的数值,相应的,所述终端设备可以将该数值直接作为所述第一BWP的大小。
再进一步来说,所述第一BWP的大小,在M个第二服务小区不同且所述第一BWP的大小的确定方式不同的情况下是不同的,下面分别来说:
情况1、所述M个第二服务小区可以是同一小区调度的服务小区。第一BWP的大小为M个第二服务小区的激活BWP的频域资源总和。
也就是说,第一BWP的大小,由一个服务小区的第一DCI所能够调度的M个第二服务小区的激活BWP的总和确定。
比如第一DCI为M个第二服务小区中的服务小区1的第一DCI,该服务小区1用于调度服务小区1、服务小区2和服务小区3,则第一BWP的大小为服务小区1、服务小区2和服务小区3的激活BWP的频域资源总和。
举例来说,如图4所示,网络侧通过高层信令为终端配置4个第二服务小区(cell 1~cell 4),所述4个第二服务小区属于相同的cell group(如都属于MCG,或者都属于primary PUCCH group/secondary cell group)。并且,通过高层信令为终端配置的服务小区之间的调度关系如图2所示:其中,cell 1可以和cell 2一起调度,或cell1可以和cell 3一起被调度,或者,cell 2可以和cell 3一起被cell 1调度。此时,同一小区调度的服务小区可以指的是cell2和cell3,或者,cell1和cell2,或者cell1和cell3。另外,cell 1~cell 4分别包含的PRB数为50PRB,100PRB,30PRB,200PRB(编号都从RB=0开始),其中cell 1~cell 4均被配置使用type-0资源分配类型,且RBG size被配置为configuration 2(RRC配置参数rbg-Size)。
比如在图4中示意出的cell 1用于调度cell 1以及cell 1-cell3组合的search space(搜索空间)内的PDCCH所承载的第一DCI中的FDRA对应的频域资源大小(即第一BWP的大小),由包含cell 1-cell3组合的所有小区的active BWP(激活BWP)总和确定,即50+100+30=180PRB。
类似地,若cell 1用于调度cell2的search space内的PDCCH所承载的所述第一DCI中的FDRA对应的频域资源大小(即第一BWP的大小),为该cell2的激活BWP的大小即100PRB。
在cell 1用于调度cell3的search space内的PDCCH所承载的第一DCI中的FDRA对应的频域资源大小(即第一BWP的大小),为该cell3的激活BWP的大小即30PRB。
在cell4用于调度cell4的search space内的PDCCH所承载的第一DCI中的FDRA对应的频域资源大小(即第一BWP的大小),为该cell4的激活BWP的大小即为200PRB。
情况2、所述第一BWP的大小由网络设备配置。
也就是说,所述第一DCI中的FDRA域对应的频域大小即所述第一BWP的大小,可以由网络设备通过高层信令直接配置。此时,所述第一BWP的大小等于所述网络设备配置的数值。
比如,将网络设备配置的数值表示为K,也就是在用于调度服务小区的search space内的PDCCH所承载的第一DCI中的FDRA对应的频域大小为K个PRB。
情况3、M个第二服务小区为高层信令配置的服务小区或激活的服务小区的全集。所述第一BWP的大小为M个第二服务小区的激活BWP的频域资源的平均值。
也就是说,可以将全部M个第二服务小区的激活BWP的频域资源加和之后计算平均值,将该平均值作为所述第一BWP的大小。
同样以图4举例来说,M个第二服务小区为cell1~cell4,将cell1~cell4的total active BWP(总激活BWP)取平均,一般地,近似到十位,即(50+150+130+80)/4=110。
情况4、M个第二服务小区为高层信令配置的服务小区或激活的服务小区的全集。所述第一BWP的大小为M个第二服务小区的激活BWP的频域资源总和。
也就是说,可以将高层信令配置的全部服务小区或激活的全部服务小区作为M个第二服务小区,将M个第二服务小区的激活BWP的频域资源加和,作为所述第一BWP的大小。
网络设备通过高层信令配置的全部服务小区为M个第二服务小区,此时网络设备配置的全部服务小区可能仅为一个小区组中的一部分,例如,网络设备配置的M个第二服务小区为图4中所示的cell1和cell2,则第一BWP的大小等于cell 1和cell 2的频域资源总和,即50+100=150PRB。
情况5、M个第二服务小区为同小区组的服务小区。所述第一BWP的大小为M个第二服务小区的激活BWP的频域资源总和。
也就是说,可以将同一个小区组的全部M个第二服务小区的激活BWP的频域资源加和,作为所述第一BWP的大小。
同样以图4举例来说,网络设备配置的M个第二服务小区(cell1~cell4)为同一个小区组的服务小区,cell1-cell4的total active BWP(激活BWP的总和)为第一BWP的大小,即50+100+30+200=380PRB。
情况6、M个第二服务小区为高层信令配置的服务小区或激活的服务小区的子集。所述第一BWP的大小为M个第二服务小区的激活BWP的频域资源总和。
也就是说,可以将高层信令配置的全部服务小区或激活的全部服务小区中的一部分作为M个第二服务小区,将M个第二服务小区的激活BWP的频域资源加和,作为所述第一BWP的大小。
情况7、M个第二服务小区为第一服务小区组合中的服务小区;所述第一服务小区组合中的服务小区为高层信令配置的,且所述第一服务小区组合为等效激活BWP的总和最大的服务小区组合,或者,M个第二服务小区为第二服务小区组合中的服务小区;所述第二服务小区组合中的服务小区为激活的服务小区,且所述第二服务小区组合为等效激活BWP的总和最大的服务小区组合。所述第一BWP的大小为M个第二服务小区的激活BWP的频域资源总和。
也就是说,可以将高层信令配置的全部服务小区或激活的全部服务小区中分别进行组合,得到多个服务小区组合,将其中等效激活BWP的总和最大的一个服务小区组合中的全部服务小区作为M个第二服务小区。将M个第二服务小区的激活BWP的频域资源加和,作为所述第一BWP的大小。
例如,以图4为例,M个第二服务小区分别表示为cell 1~cell 4,在cell 1上调度cell 1以及cell 1-cell3组合的等效BWP包括:{50,50+100,50+30,100+30},其中,最大的等效BWP为150PRB,所以第一BWP为150PRB。
应理解,以上仅为示例性说明,实际处理中还可以包含更多种情况,只是本实施例中不进行穷举。
在以上说明的基础上,下面分别说明确定N个第一服务小区的N个数据信道所分别对应的频域资源的具体方式:
方式1、
首先,关于第一BWP的大小的确定方式与前述实施例相同,这里不做重复说明。
所述FDRA域的大小可以基于所述第一BWP的大小采用第二资源分配类型下的计算方式计算得到。其中,所述第二资源分配类型具体可以为type-1资源分配类型。
具体的,所述FDRA域的大小采用以下方式确定:
Figure PCTCN2021144065-appb-000017
其中,
Figure PCTCN2021144065-appb-000018
表示第一BWP,
Figure PCTCN2021144065-appb-000019
表示向上取整。
上述FDRA域的大小可以表示在第一DCI中包含的FDRA域中指示信息的bit位数。
所述FDRA域所指示的频域范围由所述FDRA域的大小以及所述FDRA域包含的指示信息确定。也就是说,基于所述FDRA域的大小确定所述第一DCI中FDRA域包含的指示信息的位数,从该FDRA域提取指示信息,再基于指示信息确定所述FDRA域所指示的频域范围。
具体的,由于FDRA域的大小可以采用第二资源分配类型计算得到,相应的,所述FDRA域所指示的频域范围可以基于所述第二资源分配类型对应的处理方式结合所述指示信息中的具体内容计算得到。比如:
第二资源分配类型用于分配连续的RB资源,其起始RB记作RB start,连续占用的RB数为L RBs,频域资源指示取值RIV为:
如果

Figure PCTCN2021144065-appb-000021
否则
Figure PCTCN2021144065-appb-000022
其中,L RBs≥1并且不超过
Figure PCTCN2021144065-appb-000023
是一个BWP的带宽。
终端读取RIV,可以得到对应的RB start和L RBs,即确定了FDRA域所指示的频域范围。其中,L RBs表示RB数量,RB start表示起始RB的编号;

表示BWP的大小,本实施例用其来表征第一BWP的大小;
Figure PCTCN2021144065-appb-000025
表示向下取整。
所述N个数据信道所分别对应的频域资源,由所述FDRA域所指示的频域范围以及所述N个第一服务小区的激活BWP确定。
也就是说,在得到了所述FDRA域所指示的频域范围之后,可以确定FDRA域所指示的N个第一服务小区分别对应的频域范围。
进一步地,所述N个数据信道中的第i个数据信道所对应的频域资源,为所述FDRA域所指示的频域范围与第i个第一服务小区的激活BWP的交集;
所述第i个数据信道为所述N个第一服务小区中的第i个服务小区对应的数据信道;i为大于或等于1且小于或等于N的整数。
具体的,在所述FDRA域所指示的频域范围中,可以包含N个第一服务小区级联后的全部频域范围;根据N个第一服务小区中的第i个第一服务小区的级联顺序,以及FDRA域所指示的总的频域范围,可以确定第i个第一服务小区的第i个数据信道所对应的频域范围。
下面结合图4,对本方式进行说明:
如图4所示,M等于4,也就是网络侧通过高层信令为终端配置4个第二服务小区(cell 1~cell 4),所述4个第二服务小区属于相同的cell group(如都属于MCG,或者都属于primary PUCCH group/secondary cell group)且通过高层信令为终端配置的服务小区之间的调度关系如图4所示:其中,cell 1~4可以作为单独小区被调度,cell 1可以和cell 2或cell 3一起被调度,cell 2可以和cell 3或cell 1一起被调度。
cell 1~cell 4分别包含的PRB数为50PRB,100PRB,30PRB,200PRB(编号都从RB=0开始),其中cell 1~cell 4均被配置使用type-1资源分配类型。
所述FDRA域的大小由第一BWP的大小确定。第一BWP的大小为M个第二服务小区的激活BWP的频域资源总和。
一种情况中,M个第二服务小区为所有可能调度的服务小区,基于M个第二服务小区的active BWP(激活BWP)的总和确定第一BWP的大小。
在cell 1用于调度cell 1以及cell 1~cell 3组合的search space(搜索空间)内的PDCCH(物理下行控制信道)所承载的第一DCI中,FDRA域对应的频域资源大小(即第一BWP的大小),由包含cell 1以及cell 1~cell 3组合的所有小区的active BWP总和确定,比如50+100+30=180PRB。
类似地,在cell 1用于调度cell 2的search space内的PDCCH所承载的第一DCI中的FDRA对应的频域资源大小(即第一BWP的大小),为100PRB。
在cell 1用于调度cell 3的search space内的PDCCH所承载的第一DCI中的FDRA对应的频域资 源大小(即第一BWP的大小),为30PRB。
在cell 4用于调度cell 4的search space内的PDCCH所承载的第一DCI中的FDRA对应的频域资源大小(即第一BWP的大小),为200PRB。
另一种情况中,第一BWP的大小由高层直接配置,例如在cell 1用于调度服务小区的search space内的PDCCH所承载的第一DCI中的FDRA对应的频域资源大小为K个PRB,K为网络配置的正整数。
再一种情况,第一BWP的大小为M个第二服务小区的激活BWP的频域资源的平均值。
比如图4的示例中,M个第二服务小区即cell 1~cell 4,各种第二服务小区组合的total active BWP(总激活BWP)取平均,一般地,近似到十位,即第一BWP的大小为(50+150+130+80)/4=110。
再一种情况,第一BWP的大小为M个第二服务小区的激活BWP的频域资源的总和。M个第二服务小区为同一个小区组的服务小区。
如图4的例子,M个第二服务小区即cell 1~cell 4,即第一BWP的大小为即为50+100+30+200=380PRB。
所述FDRA域的大小采用以下方式确定:
Figure PCTCN2021144065-appb-000026
其中,
Figure PCTCN2021144065-appb-000027
表示第一BWP的大小,
Figure PCTCN2021144065-appb-000028
表示向上取整。
以cell 1为例,用于调度cell 1以及cell 1-cell 3组合的search space内的PDCCH所承载的第一DCI中的FDRA域所需要的比特数(即FDRA域的大小)为
Figure PCTCN2021144065-appb-000029
Figure PCTCN2021144065-appb-000030
所述FDRA域所指示的频域范围由所述FDRA域的大小以及所述FDRA域包含的指示信息确定。
举例来说,当N个数据信道(PDSCH/PUSCH)为cell2和cell3的数据信道时,根据type-1资源分配类型的处理方式解读所述第一DCI中的FDRA域的指示信息,例如,FDRA域的指示信息为0010 0100 1011 11,可以得到FDRA域所指示的频域范围对应的PRB为31-60PRB。
所述N个第一服务小区的N个数据信道所分别对应的频域资源,由所述FDRA域所指示的频域范围以及所述N个第一服务小区的激活BWP确定。
所述N个第一服务小区中的第i个服务小区的第i个数据信道所对应的频域资源,为所述FDRA域所指示的频域范围与所述第i个服务小区的激活BWP的交集;i为大于或等于1且小于或等于N的整数。
假设N为2,第i个第一服务小区为cell 1,cell 1的激活BWP的频域范围为前50的PRB,则cell 1的第一数据信道即PDSCH/PUSCH占用了31-50PRB。若第i个服务小区为cell 3,cell 3的第二数据信道即占用了cell 3的频域资源中的第1-10PRB。
方式2、
首先,关于第一BWP的大小的确定方式与前述实施例相同,这里不做重复说明。
所述FDRA域的大小由第一BWP的大小和第一RBG的大小确定。
所述第一RBG的大小由所述第一BWP的大小确定。
在一种实施方式中,所述第一RBG的大小为基于第一资源分配类型所对应的预设信息以及所述第一BWP的大小确定的。
所述第一资源分配类型具体可以为type0,所述预设信息具体可以为type0频域资源分配类型中设置的表格,比如图2所示。
具体的,所述第一RBG的大小为基于所述第一BWP的大小从所述表格中确定的。
假设某一个服务小区对应的第一BWP的大小为180PRB,RBG size被配置为configuration 2(配置2),则查上述表格可知第一RBG的大小(size)=16。再假设另一个服务小区对应的第一BWP的大小为200PRB,则通过查上述表格可知,第一RBG的大小=16。
所述FDRA域的大小基于所述第一BWP的大小与所述第一RBG的大小的比值确定。
其中,所述FDRA域的大小具体指的是,FDRA域中包含的指示信息的比特数。
具体来说,所述FDRA域的大小由所述第一BWP的大小除以所述第一RBG的大小后向上取整得到的。
假设第一BWP的大小等于180,第一RBG的大小等于16,则FDRA域的大小即为
Figure PCTCN2021144065-appb-000031
所述FDRA域所指示的频域范围的指示粒度基于所述第一RBG的大小确定。
上述指示粒度还可以被称为第二RBG。
在一种方式中,该指示粒度(即第二RBG)可以等于所述第一RBG的大小。比如前述确定第一RBG的大小为16,则指示粒度等于16。
在另一种方式中,所述指示粒度基于所述N个第一服务小区的激活BWP的总和、所述第一BWP的大小以及所述第一RBG的大小确定。比如,所述终端设备基于所述N个第一服务小区的激活BWP的总和与所述第一BWP相除之后与所述第一RBG的大小相乘得到第一值,基于所述第一值确定所述指示粒度。
具体的,所述指示粒度基于第一值确定,所述第一值由所述N个第一服务小区的激活BWP的总和与所述第一BWP的大小相除之后与所述第一RBG的大小相乘。
比如,所述终端设备基于所述N个第一服务小区的激活BWP的总和与所述第一BWP的大小相除之后与所述第一RBG的大小相乘得到第二值,对所述第二值向上取整得到所述第一值;基于该第一值确定所述指示粒度。
其中,所述指示粒度等于所述第一值;
或者,所述指示粒度由所述第一值以及第一资源分配类型所对应的预设信息确定。
所述N个第一服务小区的N个数据信道所分别对应的频域资源,由所述FDRA域所指示的频域范围以及所述N个第一服务小区的激活BWP确定。
其中,所述FDRA域所指示的频域范围,由所述FDRA域的大小、所述FDRA域包含的指示信息以及所述指示粒度确定。
所述FDRA域所指示的频域范围具体可以为N个第一服务小区的所述N个数据信道所对应的总频域资源。
具体的,所述FDRA域所指示的频域范围为基于所述有效比特以及所述N个第一服务小区的频域资源范围确定的;其中,所述有效比特基于所述指示粒度以及所述N个第一服务小区的频域资源范围确定。
所述有效比特基于所述指示粒度以及所述N个第一服务小区的频域资源范围确定的处理方式,具体可以包括:
所述终端设备将所述N个第一服务小区的频域资源范围除以所述指示粒度,得到第三值,将该第三值向上取值得到的值,作为所述FDRA域包含的指示信息中的有效比特的数量。
假设N个第一服务小区的频域资源范围等于80,前述指示粒度等于8,则所述第三值等于10,将10作为所述FDRA域包含的指示信息中的有效比特的数量。
也就是说,所述FDRA域的指示信息的比特数等于FDRA域的大小,而所述有效比特为FDRA域中的一部分。
在一些实施例中,所述FDRA域包含的指示信息中的有效比特为从前向后提取的,假设FDRA域包含的指示信息包含12比特,有效比特为前10个比特。
所述FDRA域所指示的频域范围为基于所述有效比特以及所述N个第一服务小区的频域资源范围确定的,具体指的是:在第j位有效比特为第一值的情况下,该第j位有效比特对应的频域资源上没有传输数据信道;在第j位有效比特为第二值的情况下,该第j位有效比特对应的频域资源上传输数据信道。其中,第一值为0,第二值为1。
所述N个数据信道中的第i个数据信道所对应的频域资源,为所述FDRA域所指示的频域范围与第i个第一服务小区的激活BWP的交集;
所述第i个数据信道为所述N个第一服务小区中的第i个服务小区对应的数据信道;i为大于或等于1且小于或等于N的整数。
也就是说,根据第i个服务小区在N个第一服务小区中的指示顺序,以及第i个服务小区的激活BWP的大小,可以确定FDRA域中指示的频域范围中与第i个服务小区的激活BWP的频域范围的交集。
进一步地,在FDRA域中存在N个第一服务小区的指示顺序,可以是按照第一服务小区的编号(或索引)从低到高的顺序排列,或者可以按照其他默认方式排列,本实施例不对其进行限定。可以在确定了FDRA域指示的总的频域范围的情况下,基于N个第一服务小区的指示顺序,分别确定每一个第一服务小区的频域范围。比如,第i个第一服务小区为第1个服务小区,其激活BWP的大小为预先得知的,然后基于自身的激活BWP大小与该第1个服务小区在FDRA域指示的总的频域范围的排序为第1个,来确定本次指示的该第1个服务小区的激活BWP的大小范围内的频域范围,将该频域范围作为第i个数据信道所对应的频域范围。
下面结合图4,对本方式进行第一种说明:
如图4所示,M等于4,也就是网络侧通过高层信令为终端配置4个第二服务小区(cell 1~cell 4),所述4个第二服务小区属于相同的cell group(如都属于MCG,或者都属于primary PUCCH group/secondary cell group)且通过高层信令为终端配置的服务小区之间的调度关系如图4所示:其中,cell 1~4可以作为单独小区被调度,cell 1可以和cell 2或cell 3一起被调度,cell 2可以和cell 3或cell 1 一起被调度。
cell 1~cell 4分别包含的PRB数为50PRB,100PRB,30PRB,200PRB(编号都从RB=0开始),其中cell 1~cell 4均被配置使用type-0频域资源分配类型。
所述FDRA域的大小由第一BWP的大小确定。
一种情况中,M个第二服务小区为所有可能调度的服务小区,基于M个第二服务小区的active BWP(激活BWP)的总和确定第一BWP的大小。
在cell 1用于调度cell 1以及cell 1~cell 3组合的search space(搜索空间)内的PDCCH(物理下行控制信道)所承载的第一DCI中,FDRA域对应的频域资源大小(即第一BWP的大小),由包含cell 1以及cell 1~cell 3组合的所有小区的active BWP总和确定,比如50+100+30=180PRB。
类似地,在cell 1用于调度cell 2的search space内的PDCCH所承载的第一DCI中的FDRA对应的频域资源大小(即第一BWP的大小),为100PRB。
在cell 1用于调度cell 3的search space内的PDCCH所承载的第一DCI中的FDRA对应的频域资源大小(即第一BWP的大小),为30PRB。
在cell 4用于调度cell 4的search space内的PDCCH所承载的第一DCI中的FDRA对应的频域资源大小(即第一BWP的大小),为200PRB。
另一种情况中,第一BWP的大小由高层直接配置,例如在cell 1用于调度服务小区的search space内的PDCCH所承载的第一DCI中的FDRA对应的频域资源大小为K个PRB,K为网络配置的正整数。
再一种情况,第一BWP的大小为M个第二服务小区的激活BWP的频域资源的平均值。
比如图4的示例中,M个第二服务小区即cell 1~cell 4,各种第二服务小区组合的total active BWP(总激活BWP)取平均,一般地,近似到十位,即第一BWP的大小为(50+150+130+80)/4=110。
再一种情况,第一BWP的大小为M个第二服务小区的激活BWP的频域资源的总和。M个第二服务小区为同一个小区组的服务小区。
如图4的例子,M个第二服务小区即cell 1~cell 4,即第一BWP的大小为即为50+100+30+200=380PRB。
另一种情况,第一BWP的大小由M个第二服务小区确定,M个第二服务小区由高层信令配置。例如,第一BWP的大小由cell 1~cell 2确定,即第一BWP的大小为50+100=150PRB。
又一种情况,第一BWP的大小由M个第二服务小区确定,M个第二服务小区是配置的或者激活的服务小区的子集或全集;例如,第一BWP的大小由cell 2确定,cell 2是由cell1调度的配置的或者激活的服务小区中的一个服务小区。
第一RBG的大小至少由第一BWP的大小确定。
以cell1为例,cell1对应的第一BWP的大小为180PRB,RBG size被配置为configuration 2,则查表(如图2所示)可知第一RBG的大小=16。
FDRA域的大小由第一BWP的大小和第一RBG的大小确定。即FDRA域的大小等于第一BWP的大小除以第一RBG的大小后向上取值得到的。
以cell1为例,用于调度cell1以及cell1、cell2和cell3组合的search space内的PDCCH所承载的第一DCI中的FDRA域的大小为
Figure PCTCN2021144065-appb-000032
确定指示粒度:一种方式中,所述指示粒度等于第一RBG size(大小),即16。
另一种方式中,所述指示粒度基于所述N个第一服务小区的激活BWP的总和、所述第一BWP的大小以及所述第一RBG的大小确定。
以cell1为例,用于调度cell 1和cell3的2个PDSCH/PUSCH时,其N个第一服务小区的激活BWP的总和为:50+30=80PRBs。假设第一BWP的大小等于180,第一RBG的大小等于16,则所述指示粒度
Figure PCTCN2021144065-appb-000033
这样在保持FDRA域大小不变的情况下,尽可能指示精确,即尽可能小的RBG size,则可以根据实际调度的服务小区的active BWP的总和进行等比例调整。
进一步,所述指示粒度由所述第一值以及第一资源分配类型所对应的预设信息确定,也就是从type0资源配置类型约定的RBG size中找一个最接近且大于等于该计算值的RBG size作为所述指示粒度。以上述示例计算出来的第一值等于7PRB为例来说,通过查表可以得到最接近的值为8,因此确定所述指示粒度为8PRBs。
所述N个数据信道所分别对应的频域资源,由所述FDRA域所指示的频域范围以及所述N个第一服务小区的激活BWP确定。
以cell1为例,用于调度cell1和cell3的2个PDSCH/PUSCH时,对应80PRBs的频域资源;前面 已经确定第一DCI中的FDRA域的大小为12,在确定第二RBG size大小(即指示粒度)为8时,可以确定FDRA域中的指示信息的12比特中的前10比特为有效比特,比如表示为0110110100xx。
上述前10bit对应第2,3,5,6,8个RBG。结合所述指示粒度,可以确定第2组RBG包含了8PRB,也就是从第9-16个PRB上传输了数据信道,以此类推。
假设N为2,第i个服务小区为2个服务小区中的cell1,cell1的激活BWP的频域范围为前50的PRB,则cell1的PDSCH/PUSCH占用了第9-24,33-48PRB。若第i个服务小区为cell3,cell3的active BWP的频域范围为30PRB时,cell3的PDSCH/PUSCH占用了第57-64PRB。
下面结合图4,对本方式进行第二种说明:
如图4所示,M等于4,也就是网络侧通过高层信令为终端配置4个第二服务小区(cell 1~cell 4),所述4个第二服务小区属于相同的cell group(如都属于MCG,或者都属于primary PUCCH group/secondary cell group)且通过高层信令为终端配置的服务小区之间的调度关系如图4所示:其中,cell 1~4可以作为单独小区被调度,cell 1可以和cell 2或cell 3一起被调度,cell 2可以和cell 3或cell 1一起被调度。
cell 1~cell 4分别包含的PRB数为50PRB,100PRB,30PRB,200PRB(编号都从RB=0开始),其中cell 1~cell 4均被配置使用type-0频域资源分配类型,且RBG size被配置为configuration 2(RRC配置参数rbg-Size),则
所述FDRA域的大小由第一BWP的大小确定。
一种情况中,M个第二服务小区为第一服务小区组合中的服务小区;所述第一服务小区组合中的服务小区为高层信令配置的,且所述第一服务小区组合为等效激活BWP的总和最大的服务小区组合,第一BWP的大小由M个第二服务小区的总和确定。
也就是在cell 1用于调度cell 1以及cell 1~cell 3组合的search space(搜索空间)内的PDCCH(物理下行控制信道)所承载的第一DCI中,FDRA域对应的频域资源大小(即第一BWP的大小)由包含cell 1以及cell 1~cell 3组合的等效active BWP最大的组合确定。以图4为例,在cell 1上调度cell 1以及cell 1~cell 3组合的等效BWP包括:{50,50+100,50+30,100+30},其中,最大的等效BWP为150PRB,所以第一BWP的大小为150PRB。
在cell 4用于调度cell 4的search space内的PDCCH所承载的第一DCI中的FDRA对应的频域资源大小(即第一BWP的大小),为200PRB。
又一种情况,第一BWP的大小由M个第二服务小区确定,M个第二服务小区是配置的或者激活的服务小区的子集或全集;
第一BWP的大小由M个第二服务小区确定,M个第二服务小区为配置的或者激活的所有服务小区任意组合的子集或全集的等效active BWP最大的组合。例如,cell 1为配置的或者激活的所有服务小区的等效active BWP最大的组合,即cell 1的第一BWP的大小为50PRB。
例如,对于cell 1,M个小区为配置的或者激活的所有第二服务小区即cell 1~cell 3组合的等效active BWP最大的组合,即{50+100,50+30,100+30}中最大的active BWP,即第一BWP的大小为150PRBs。
例如,第一BWP的大小由M个第二服务小区确定,M个第二服务小区高层配置的服务小区和服务小区的任意组合的等效active BWP最大的组合。例如,高层配置cell 1和cell 1~cell 2组合来确定FDRA域的大小,所以,第一BWP的大小为{50,100+50}中最大的值,即150PRB。
另一种情况中,第一BWP的大小由高层直接配置。例如在一个服务小区用于调度第一服务小区的search space内的PDCCH所承载的第一DCI中的FDRA对应的频域资源大小(即第一BWP的大小)为K个PRB,K为网络配置的正整数。
再一种情况,第一BWP的大小为M个第二服务小区的激活BWP的频域资源的平均值。
比如图4的示例中,M个第二服务小区即cell 1~cell 4,各种第二服务小区组合的total active BWP(总激活BWP)取平均,一般地,近似到十位,即第一BWP的大小为(50+150+130+80)/4=110。
再一种情况,第一BWP的大小为M个第二服务小区的激活BWP的频域资源的总和。M个第二服务小区为同一个小区组的服务小区。
如图4的例子,M个第二服务小区即cell 1~cell 4,即第一BWP的大小为即为50+100+30+200=380PRB。
第一RBG的大小至少由第一BWP的大小确定。
以cell1为例,cell1对应的第一BWP的大小为180PRB,RBG size被配置为configuration 2,则查表(如图2所示)可知第一RBG的大小=16。
FDRA域的大小由第一BWP的大小和第一RBG的大小确定。即FDRA域的大小等于第一BWP的大小除以第一RBG的大小后向上取值得到的。
以cell1为例,用于调度cell1以及cell1、cell2和cell3组合的search space内的PDCCH所承载的第一DCI中的FDRA域的大小为
Figure PCTCN2021144065-appb-000034
确定指示粒度:一种方式中,所述指示粒度等于第一RBG size(大小),即16。
另一种方式中,所述指示粒度基于所述N个第一服务小区的激活BWP的总和、所述第一BWP的大小以及所述第一RBG的大小确定。
以cell1为例,用于调度cell 1和cell3的2个PDSCH/PUSCH时,其N个第一服务小区的激活BWP的总和为:50+30=80PRBs。假设第一BWP的大小等于150,第一RBG的大小等于16,则所述指示粒度
Figure PCTCN2021144065-appb-000035
这样在保持FDRA域大小不变的情况下,尽可能指示精确,即尽可能小的RBG size,则可以根据实际调度的服务小区的active BWP的总和进行等比例调整。
进一步,所述指示粒度由所述第一值以及第一资源分配类型所对应的预设信息确定,也就是从type0资源配置类型约定的RBG size中找一个最接近且大于等于该计算值的RBG size作为所述指示粒度。以上述示例计算出来的第一值等于9PRB为例来说,通过查表可以得到最接近的值为9,因此确定所述指示粒度为9PRBs。
所述N个数据信道所分别对应的频域资源,由所述FDRA域所指示的频域范围以及所述N个第一服务小区的激活BWP确定。
以cell1为例,用于调度cell1和cell3的2个PDSCH/PUSCH时,对应80PRBs的频域资源;前面已经确定第一DCI中的FDRA域的大小为10,且确定第二RBG size大小(即指示粒度)为9时,则FDRA域中的10比特的前9比特为有效比特,对应80PRBs的频域资源。所以,011011011x对应第2,3,5,6,8,9个RBG。
结合所述指示粒度,可以确定第2组RBG包含了9PRB,也就是从第10-18个PRB上传输了数据信道,以此类推。
假设N为2,第i个服务小区为2个服务小区中的cell1,cell1的激活BWP的频域范围为前50的PRB,则cell1的PDSCH/PUSCH占用了cell1的第10-27,37-50PRB,cell3的PDSCH/PUSCH占用了cell3的第1-4,14-30PRB。
应理解,本实施例提供的方案虽然针对了FDRA域进行了说明,实际处理中,针对其他类型的资源的指示方式也均可以包括在本实施例的保护范围内,比如针对时域资源分配也可以采用上述方案来实现,将上述频域范围替换为时域范围,以及频域资源替换为时域资源也同样适用,只是时域资源的单位可以变成时隙、OFDM符号等等,这里不做穷举。
可见,通过采用上述方案,可以在第一DCI中调度N个第一服务小区的N个数据信道,从而即可以保持独立指示的灵活性,并且由于第一DCI的FDRA域的频域大小是基于M个第二服务小区的激活BWP确定的,而M个第二服务小区的激活BWP总和大于等于所述N个第一服务小区的激活BWP总和,因此该第一DCI还可以让多个服务小区共享一个指示域,从而减少FDRA域的指示开销。
图5是根据本申请一实施例的资源的指示方法的示意性流程图。该方法可以应用于图1所示的系统中的网络设备,但并不仅限于此。该方法包括以下内容的至少部分内容。
S510、网络设备向终端设备发送第一下行控制信息(DCI,Downlink Control Information);
其中,所述第一DCI用于调度N个第一服务小区的N个数据信道;所述第一DCI中包含频域资源分配指示(FDRA,Frequency domain resource assignment)域,所述FDRA域所指示的频域大小由M个第二服务小区的激活BWP确定;所述M个第二服务小区的激活BWP总和大于等于所述N个第一服务小区的激活BWP总和;M为正整数,N为正整数。
所述M个第二服务小区,可以是按照规则确定的。

具体的,所述同小区组的服务小区,可以指的是同一个小区组的全部服务小区。关于小区组可以为网络设备通过高层信令为所述终端设备配置。比如,网络侧通过高层信令为终端设备配置4个服务小区 (cell 1~cell 4),并配置所述4个服务小区属于相同的cell group(小区组),如都属于MCG(Master Cell group,主小区组),或者都属于primary PUCCH group(主PUCCH组)/SCG(Secondary Cell group,辅小区组)。此时,上述4个服务小区(cell 1~cell 4)可以为M个第二服务小区。
所述在同一小区调度的服务小区,可以是:在一个服务小区传输的所述第一DCI能够调度的服务小区。
比如,所述网络设备可以为所述终端设备配置服务小区之间的调度关系。参见图4来说,网络侧通过高层信令为终端设备配置4个服务小区,分别为cell 1~cell 4;其中,cell 1可以和cell 2一起调度,或cell1可以和cell 3一起被调度,或者,cell 2可以和cell 3一起被cell 1调度。此时,同一小区调度的服务小区可以指的是cell2和cell3,或者,cell1和cell2,或者cell1和cell3。则在cell 1传输的第一DCI,可以是用于调度cell1~cell3的任意组合中包含的服务小区,则该cell 1、cell2和cell3中的任意组合为cell1这个小区能够调度的M个第二服务小区。
进一步地,所述同一小区调度的服务小区为:所述同一小区的同一个搜索空间的物理下行数据信道(PDCCH,Physical Downlink Control Channel)调度的服务小区。也就是说,所述M个第二服务小区为某一个小区在同一个搜索空间(search space)的PDCCH调度的全部服务小区。
为终端设备配置的服务小区中的至少部分服务小区,具体可以指的是:网络设备通过高层信令为终端设备配置的全部服务小区中的子集或全集。举例来说,网络侧通过高层信令为终端设备配置4个服务小区,分别为cell 1~cell 4,可以将上述cell1~cell4作为前述M个第二服务小区;或者,将cell1和cell2作为前述M个第二服务小区等等,这里不做穷举。
上述M个第二服务小区为所述网络设备第一服务小区组合中的服务小区;所述第一服务小区组合中的服务小区为网络设备为终端设备配置的,且所述第一服务小区组合为等效激活BWP的总和最大的服务小区组合,其确定方式可以是:将网络设备通过高层信令为终端设备配置的全部服务小区分别进行组合,得到多个服务小区组合;计算所述多个服务小区组合的等效激活BWP的总和,将等效激活BWP的总和最大的一个服务小区组合中的全部服务小区作为前述M个第二服务小区。
激活的服务小区中的至少部分激活的服务小区,可以为:激活的所有服务小区任意组合的子集或全集。举例来说,当前激活的服务小区有3个服务小区,分别为cell 1~cell 3,可以将上述cell1~cell3作为前述M个第二服务小区;或者,将cell1和cell2作为前述M个第二服务小区等等,这里不做穷举。
上述M个第二服务小区为第二服务小区组合中的服务小区;所述第二服务小区组合中的服务小区为激活的服务小区,且所述第二服务小区组合为等效激活BWP的总和最大的服务小区组合,其确定方式可以是:将当前激活的全部服务小区分别进行组合,得到多个服务小区组合;计算所述多个服务小区组合的等效激活BWP的总和,将等效激活BWP的总和最大的一个服务小区组合中的全部服务小区作为前述M个第二服务小区。
其中,所述等效激活BWP的总和,指的是:每个服务小区组中全部服务小区的激活BWP的总和。
在前述基础上,一种实施方式中,所述M个第二服务小区中包含目标小区;所述目标小区为所述第一DCI调度的小区。也就是说,在原处理机制中,网络设备通过DCI调度cell 1;在本公开提供的实施方式中,上述M个第二服务小区包含上述cell 1。
其中,所述N个第一服务小区可以为一个或多个,具体与当前所要调度的服务小区的数量相关。
所述N个第一服务小区中每个第一服务小区对应一个数据信道,即所述N个第一服务小区与所述N个数据信道为一一对应的关系。
上述数据信道具体可以包括:PDSCH(物理下行共享信道,Physical Downlink Share CHannel)或者PUSCH(物理上行共享信道,Physical Uplink Share CHannel)。
所述N个第一服务小区由以下之一指示:高层信令,所述第一DCI,第二DCI;所述第二DCI与所述第一DCI不同。
也就是说,上述N个第一服务小区由高层信令配置,或者由所述第一DCI指示,或者由其他DCI指示。应理解,所述第一DCI指的为包含FDRA域的DCI,而所述网络设备可以为终端设备下发的还有其他DCI,本公开实施例中将其他DCI中任意之一称为第二DCI。
所述N个第一服务小区可以为M个第二服务小区的子集或全集,且所述N个第一服务小区的激活BWP总和小于或等于所述M个第二服务小区的激活BWP总和。比如,所述网络设备可以预先通过高层信令为终端设备发送配置的M个第二服务小区;然后网络设备再通过第一DCI(或第二DCI,或高层信令)为终端设备配置M个第二服务小区中的N个第一服务小区。又比如,所述终端设备按照规则确定M个第二服务小区;然后网络设备再通过第一DCI(或第二DCI,或高层信令)为终端设备配置M个第二服务小区中的N个第一服务小区。
或者,所述N个第一服务小区与所述M个第二服务小区不同,且所述N个第一服务小区的激活 BWP总和小于或等于所述M个第二服务小区的激活BWP总和。举例来说,所述M个第二服务小区可以为系统中的部分服务小区,比如服务小区1-5,其激活BWP总和为200PRB;N个第一服务小区可以为服务小区7和服务小区8,其激活BWP总和为100PRB。
或者,所述N个第一服务小区与所述M个第二服务小区存在交集,且所述N个第一服务小区的激活BWP总和小于或等于所述M个第二服务小区的激活BWP总和。举例来说,所述M个第二服务小区可以为系统中的部分服务小区,比如服务小区1-5,其激活BWP总和为200PRB;N个第一服务小区可以为服务小区3和服务小区8,其激活BWP总和为150PRB。
在前述基础上,一种实施方式中,所述N个第一服务小区中包含目标小区;所述目标小区为所述第一DCI调度的小区。也就是说,在原处理机制中,网络设备通过DCI调度cell 1;在本公开提供的实施方式中,上述N个第一服务小区中包含cell 1。
所述FDRA域的大小由第一BWP的大小确定;其中,所述第一BWP的大小为以下之一:
M个第二服务小区的激活BWP的频域资源总和;
M个第二服务小区的激活BWP的频域资源的平均值。
所述第一BWP的大小即所述FDRA域所能够指示的最大频域范围,或者所述第一BWP的大小为所述FDRA域所指示的频域大小。也就是说,可以基于第一BWP的大小来确定在所述第一DCI中包含的FDRA域的大小;其中FDRA域的大小具体可以指的是,所述FDRA域占用的bit位数。
其中,所述M个第二服务小区的激活BWP的频域资源总和具体可以指的是:M个第二服务小区中每个第二服务小区的激活BWP的频域资源相加得到的总和。
再进一步地,由于上述M个第二服务小区可能存在前述多种情况,相应的,所述M个第二服务小区的激活BWP的频域资源总和,可以是任意一种情况下M个第二服务小区中每个服务小区的激活BWP的频域资源相加得到的总和。
M个第二服务小区的激活BWP的频域资源的平均值的确定方式可以为:M个第二服务小区的激活BWP的频域资源相加得到总和,将该总和除以M得到平均值。
另外,所述第一BWP的大小还可以为网络设备配置的数值。比如,可以是网络设备通过高层信令配置的数值,相应的,所述终端设备可以将该数值直接作为所述第一BWP的大小。
再进一步来说,所述第一BWP的大小,在M个第二服务小区不同且所述第一BWP的大小的确定方式不同的情况下是不同的,下面分别来说:
情况1、所述M个第二服务小区可以是同一小区调度的服务小区。第一BWP的大小为M个第二服务小区的激活BWP的频域资源总和。
也就是说,第一BWP的大小,由一个服务小区的第一DCI所能够调度的M个第二服务小区的激活BWP的总和确定。
比如第一DCI为M个第二服务小区中的服务小区1的第一DCI,该服务小区1用于调度服务小区1、服务小区2和服务小区3,则第一BWP的大小为服务小区1、服务小区2和服务小区3的激活BWP的频域资源总和。
举例来说,如图4所示,网络侧通过高层信令为终端配置4个第二服务小区(cell 1~cell 4),所述4个第二服务小区属于相同的cell group(如都属于MCG,或者都属于primary PUCCH group/secondary cell group)。并且,通过高层信令为终端配置的服务小区之间的调度关系如图2所示:其中,cell 1可以和cell 2一起调度,或cell1可以和cell 3一起被调度,或者,cell 2可以和cell 3一起被cell 1调度。此时,同一小区调度的服务小区可以指的是cell2和cell3,或者,cell1和cell2,或者cell1和cell3。另外,cell 1~cell 4分别包含的PRB数为50PRB,100PRB,30PRB,200PRB(编号都从RB=0开始),其中cell 1~cell 4均被配置使用type-0频域资源分配类型,且RBG size被配置为configuration 2(RRC配置参数rbg-Size)。
比如在图4中示意出的cell 1用于调度cell 1以及cell 1-cell3组合的search space(搜索空间)内的PDCCH所承载的第一DCI中的FDRA对应的频域资源大小(即第一BWP的大小),由包含cell 1-cell3组合的所有小区的active BWP(激活BWP)总和确定,即50+100+30=180PRB。
类似地,若cell 1用于调度cell2的search space内的PDCCH所承载的所述第一DCI中的FDRA对应的频域资源大小(即第一BWP的大小),为该cell2的激活BWP的大小即100PRB。
在cell 1用于调度cell3的search space内的PDCCH所承载的第一DCI中的FDRA对应的频域资源大小(即第一BWP的大小),为该cell3的激活BWP的大小即30PRB。
在cell4用于调度cell4的search space内的PDCCH所承载的第一DCI中的FDRA对应的频域资源大小(即第一BWP的大小),为该cell4的激活BWP的大小即为200PRB。
情况2、所述第一BWP的大小由网络设备配置。
也就是说,所述第一DCI中的FDRA域对应的频域大小即所述第一BWP的大小,可以由网络设备通过高层信令直接配置给终端设备。此时,所述第一BWP的大小等于所述网络设备配置的数值。
比如,将网络设备配置的数值表示为K,也就是在用于调度服务小区的search space内的PDCCH所承载的第一DCI中的FDRA对应的频域大小为K个PRB。
情况3、M个第二服务小区为高层信令配置的服务小区或激活的服务小区的全集。所述第一BWP的大小为M个第二服务小区的激活BWP的频域资源的平均值。
也就是说,可以将全部M个第二服务小区的激活BWP的频域资源加和之后计算平均值,将该平均值作为所述第一BWP的大小。
同样以图4举例来说,M个第二服务小区为cell1~cell4,将cell1~cell4的total active BWP(总激活BWP)取平均,一般地,近似到十位,即(50+150+130+80)/4=110。
情况4、M个第二服务小区为配置的服务小区或激活的服务小区的全集。所述第一BWP的大小为M个第二服务小区的激活BWP的频域资源总和。
也就是说,网络设备可以将通过高层信令为终端设备配置的全部服务小区或激活的全部服务小区作为M个第二服务小区,将M个第二服务小区的激活BWP的频域资源加和,作为所述第一BWP的大小。
网络设备配置的全部服务小区可能仅为一个小区组中的一部分,例如,网络设备配置的M个第二服务小区为图4中所示的cell1和cell2,则第一BWP的大小等于cell 1和cell 2的频域资源总和,即50+100=150PRB。
情况5、M个第二服务小区为同小区组的服务小区。所述第一BWP的大小为M个第二服务小区的激活BWP的频域资源总和。
也就是说,可以将同一个小区组的全部M个第二服务小区的激活BWP的频域资源加和,作为所述第一BWP的大小。
同样以图4举例来说,网络设备可以将通过高层信令为终端设备配置的M个第二服务小区(cell1~cell4)为同一个小区组的服务小区,cell1-cell4的total active BWP(激活BWP的总和)为第一BWP的大小,即50+100+30+200=380PRB。
情况6、M个第二服务小区为高层信令配置的服务小区或激活的服务小区的子集。所述第一BWP的大小为M个第二服务小区的激活BWP的频域资源总和。
也就是说,网络设备可以将通过高层信令为终端设备配置的全部服务小区或激活的全部服务小区中的一部分,作为M个第二服务小区,将M个第二服务小区的激活BWP的频域资源加和,作为所述第一BWP的大小。
情况7、M个第二服务小区为第一服务小区组合中的服务小区;所述第一服务小区组合中的服务小区为高层信令配置的,且所述第一服务小区组合为等效激活BWP的总和最大的服务小区组合,或者,M个第二服务小区为第二服务小区组合中的服务小区;所述第二服务小区组合中的服务小区为激活的服务小区,且所述第二服务小区组合为等效激活BWP的总和最大的服务小区组合。所述第一BWP的大小为M个第二服务小区的激活BWP的频域资源总和。
也就是说,网络设备可以将通过高层信令为终端设备配置的全部服务小区或激活的全部服务小区中分别进行组合,得到多个服务小区组合,将其中等效激活BWP的总和最大的一个服务小区组合中的全部服务小区作为M个第二服务小区。将M个第二服务小区的激活BWP的频域资源加和,作为所述第一BWP的大小。
例如,以图4为例,M个第二服务小区分别表示为cell 1~cell 4,在cell 1上调度cell 1以及cell 1-cell 3组合的等效BWP包括:{50,50+100,50+30,100+30},其中,最大的等效BWP为150PRB,所以第一BWP的大小为150PRB。
应理解,以上仅为示例性说明,实际处理中还可以包含更多种情况,只是本实施例中不进行穷举。
在以上说明的基础上,下面分别说明确定N个第一服务小区的N个数据信道所分别对应的频域资源的具体方式:
方式1、
首先,关于第一BWP的大小的确定方式与前述实施例相同,这里不做重复说明。
所述FDRA域的大小可以基于所述第一BWP的大小采用第二资源分配类型下的计算方式计算得到。其中,所述第二资源分配类型具体可以为type-1频域资源分配类型。
具体的,所述FDRA域的大小采用以下方式确定:
Figure PCTCN2021144065-appb-000036
其中,
Figure PCTCN2021144065-appb-000037
表示第一BWP的大小。
上述FDRA域的大小可以表示在第一DCI中包含的FDRA域中指示信息的bit位数。
所述FDRA域所指示的频域范围由所述FDRA域的大小以及所述FDRA域包含的指示信息确定。也就是说,基于所述FDRA域的大小确定所述第一DCI中FDRA域包含的指示信息的位数,从该FDRA域提取指示信息,再基于指示信息确定所述FDRA域所指示的频域范围。
具体的,由于FDRA域的大小可以采用第二资源分配类型计算得到,相应的,所述FDRA域所指示的频域范围可以基于所述第二资源分配类型对应的处理方式结合所述指示信息中的具体内容计算得到。比如:
所述N个数据信道所分别对应的频域资源,由所述FDRA域所指示的频域范围以及所述N个第一服务小区的激活BWP确定。
也就是说,在得到了所述FDRA域所指示的频域范围之后,可以确定FDRA域所指示的N个第一服务小区分别对应的频域范围。
进一步地,所述N个数据信道中的第i个数据信道所对应的频域资源,为所述FDRA域所指示的频域范围与第i个第一服务小区的激活BWP的交集;
所述第i个数据信道为所述N个第一服务小区中的第i个服务小区对应的数据信道;i为大于或等于1且小于或等于N的整数。
具体的,在所述FDRA域所指示的频域范围中,可以包含N个第一服务小区级联后的全部频域范围;根据N个第一服务小区中的第i个第一服务小区的级联顺序,以及FDRA域所指示的总的频域范围,可以确定第i个第一服务小区的第i个数据信道所对应的频域范围。
下面结合图4,对本方式进行说明:
如图4所示,M等于4,也就是网络侧通过高层信令为终端配置4个第二服务小区(cell 1~cell 4),所述4个第二服务小区属于相同的cell group(如都属于MCG,或者都属于primary PUCCH group/secondary cell group)且通过高层信令为终端配置的服务小区之间的调度关系如图4所示:其中,cell 1~4可以作为单独小区被调度,cell 1可以和cell 2或cell 3一起被调度,cell 2可以和cell 3或cell 1一起被调度。
cell 1~cell 4分别包含的PRB数为50PRB,100PRB,30PRB,200PRB(编号都从RB=0开始),其中cell 1~cell 4均被配置使用type-1频域资源分配类型。
所述FDRA域的大小由第一BWP的大小确定。第一BWP的大小为M个第二服务小区的激活BWP的频域资源总和。
一种情况中,M个第二服务小区为所有可能调度的服务小区,基于M个第二服务小区的active BWP(激活BWP)的总和确定第一BWP的大小。
在cell 1用于调度cell 1以及cell 1~cell 3组合的search space(搜索空间)内的PDCCH(物理下行控制信道)所承载的第一DCI中,FDRA域对应的频域资源大小(即第一BWP的大小),由包含cell 1以及cell 1~cell 3组合的所有小区的active BWP总和确定,比如50+100+30=180PRB。
类似地,在cell 1用于调度cell 2的search space内的PDCCH所承载的第一DCI中的FDRA对应的频域资源大小(即第一BWP的大小),为100PRB。
在cell 1用于调度cell 3的search space内的PDCCH所承载的第一DCI中的FDRA对应的频域资源大小(即第一BWP的大小),为30PRB。
在cell 4用于调度cell 4的search space内的PDCCH所承载的第一DCI中的FDRA对应的频域资源大小(即第一BWP的大小),为200PRB。
另一种情况中,第一BWP的大小由高层直接配置,例如在cell 1用于调度服务小区的search space内的PDCCH所承载的第一DCI中的FDRA对应的频域资源大小为K个PRB,K为网络配置的正整数。
再一种情况,第一BWP的大小为M个第二服务小区的激活BWP的频域资源的平均值。
比如图4的示例中,M个第二服务小区即cell 1~cell 4,各种第二服务小区组合的total active BWP(总激活BWP)取平均,一般地,近似到十位,即第一BWP的大小为(50+150+130+80)/4=110。
再一种情况,第一BWP的大小为M个第二服务小区的激活BWP的频域资源的总和。M个第二服务小区为同一个小区组的服务小区。
如图4的例子,M个第二服务小区即cell 1~cell 4,即第一BWP的大小为即为50+100+30+200=380PRB。
所述FDRA域的大小采用以下方式确定:
Figure PCTCN2021144065-appb-000038
其中,
Figure PCTCN2021144065-appb-000039
表示第一BWP的大小。
以cell 1为例,用于调度cell 1以及cell 1-cell 3组合的search space内的PDCCH所承载的第一DCI 中的FDRA域所需要的比特数(即FDRA域的大小)为
Figure PCTCN2021144065-appb-000040
Figure PCTCN2021144065-appb-000041
所述FDRA域所指示的频域范围由所述FDRA域的大小以及所述FDRA域包含的指示信息确定。
举例来说,当N个数据信道(PDSCH/PUSCH)为cell2和cell3的数据信道时,根据type-1频域资源分配类型的处理方式解读所述第一DCI中的FDRA域的指示信息,例如,FDRA域的指示信息为0010 0100 1011 11,可以得到FDRA域所指示的频域范围对应的PRB为31-60PRB。
所述N个数据信道所分别对应的频域资源,由所述FDRA域所指示的频域范围以及所述N个第一服务小区的激活BWP确定。
所述N个第一服务小区中的第i个服务小区的第i个数据信道所对应的频域资源,为所述FDRA域所指示的频域范围与所述第i个服务小区的激活BWP的交集;i为大于或等于1且小于或等于N的整数。
假设N为2,第i个第一服务小区为cell 1,cell 1的激活BWP的频域范围为前50的PRB,则cell 1的第一数据信道即PDSCH/PUSCH占用了31-50PRB。若第i个服务小区为cell 3,cell 3的第二数据信道即占用了cell 3的频域资源中的第1-10PRB。
方式2、
首先,关于第一BWP的大小的确定方式与前述实施例相同,这里不做重复说明。
所述FDRA域的大小由第一BWP的大小和第一RBG的大小确定。
所述第一RBG的大小由所述第一BWP的大小确定。
在一种实施方式中,所述第一RBG的大小为基于第一资源分配类型所对应的预设信息以及所述第一BWP的大小确定的。
所述第一资源分配类型具体可以为type0,所述预设信息具体可以为type0频域资源分配类型中设置的表格,比如图2所示。
具体的,所述第一RBG的大小为基于所述第一BWP的大小从所述表格中确定的。
假设某一个服务小区对应的第一BWP的大小为180PRB,RBG size被配置为configuration 2(配置2),则查上述表格可知第一RBG的大小(size)=16。再假设另一个服务小区对应的第一BWP的大小为200PRB,则通过查上述表格可知,第一RBG的大小=16。
所述FDRA域的大小由所述第一BWP除以所述第一RBG的大小确定。
其中,所述FDRA域的大小具体指的是,FDRA域中包含的指示信息的比特数。
具体来说,所述FDRA域的大小基于所述第一BWP的大小与所述第一RBG的大小的比值确定。
假设第一BWP的大小等于180,第一RBG的大小等于16,则FDRA域的大小即为

所述FDRA域所指示的频域范围的指示粒度基于所述第一RBG的大小确定。
上述指示粒度还可以被称为第二RBG。
在一种方式中,该指示粒度(即第二RBG)可以等于所述第一RBG的大小。比如前述确定第一RBG的大小为16,则指示粒度等于16。
在另一种方式中,所述指示粒度基于所述N个第一服务小区的激活BWP的总和、所述第一BWP的大小以及所述第一RBG的大小确定。比如,所述终端设备基于所述N个第一服务小区的激活BWP的总和与所述第一BWP的大小相除之后与所述第一RBG的大小相乘得到第一值,基于所述第一值确定所述指示粒度。
具体的,所述指示粒度基于第一值确定,所述第一值由所述N个第一服务小区的激活BWP的总和与所述第一BWP的大小相除之后与所述第一RBG的大小相乘。
比如,所述终端设备基于所述N个第一服务小区的激活BWP的总和与所述第一BWP的大小相除之后与所述第一RBG的大小相乘得到第二值,对所述第二值向上取整得到所述第一值;基于该第一值确定所述指示粒度。
其中,所述指示粒度等于所述第一值;
或者,所述指示粒度由所述第一值以及第一资源分配类型所对应的预设信息确定。
所述N个数据信道所分别对应的频域资源,由所述FDRA域所指示的频域范围以及所述N个第一服务小区的激活BWP确定。
其中,所述FDRA域所指示的频域范围,由所述FDRA域的大小、所述FDRA域包含的指示信息以及所述指示粒度确定。
所述FDRA域所指示的频域范围具体可以为N个第一服务小区的所述N个数据信道所对应的总频域资源。
具体的,所述FDRA域所指示的频域范围为基于所述有效比特以及所述N个第一服务小区的频域 资源范围确定的;其中,所述有效比特基于所述指示粒度以及所述N个第一服务小区的频域资源范围确定。
所述有效比特基于所述指示粒度以及所述N个第一服务小区的频域资源范围确定的处理方式,具体可以包括:
所述终端设备将所述N个第一服务小区的频域资源范围除以所述指示粒度,得到第三值,将该第三值向上取值得到的值,作为所述FDRA域包含的指示信息中的有效比特的数量。
假设N个第一服务小区的频域资源范围等于80,前述指示粒度等于8,则所述第三值等于10,将10作为所述FDRA域包含的指示信息中的有效比特的数量。
也就是说,所述FDRA域的指示信息的比特数等于FDRA域的大小,而所述有效比特为FDRA域中的一部分。
在一些实施例中,所述FDRA域包含的指示信息中的有效比特为从前向后提取的,假设FDRA域包含的指示信息包含12比特,有效比特为前10个比特。
所述FDRA域所指示的频域范围为基于所述有效比特以及所述N个第一服务小区的频域资源范围确定的,具体指的是:在第j位有效比特为第一值的情况下,该第j位有效比特对应的频域资源上没有传输数据信道;在第j位有效比特为第二值的情况下,该第j位有效比特对应的频域资源上传输数据信道。其中,第一值为0,第二值为1。
所述N个第一服务小区中的第i个服务小区的第i个数据信道所对应的频域资源,为所述FDRA域所指示的频域范围与所述第i个服务小区的激活BWP的交集;i为大于或等于1且小于或等于N的整数。
也就是说,根据第i个服务小区在N个第一服务小区中的顺序,以及第i个服务小区的激活BWP的大小,可以确定FDRA域中指示的频域范围中与第i个服务小区的激活BWP的频域范围的交集。
下面结合图4,对本方式进行第一种说明:
如图4所示,M等于4,也就是网络侧通过高层信令为终端配置4个第二服务小区(cell 1~cell 4),所述4个第二服务小区属于相同的cell group(如都属于MCG,或者都属于primary PUCCH group/secondary cell group)且通过高层信令为终端配置的服务小区之间的调度关系如图4所示:其中,cell 1~4可以作为单独小区被调度,cell 1可以和cell 2或cell 3一起被调度,cell 2可以和cell 3或cell 1一起被调度。
cell 1~cell 4分别包含的PRB数为50PRB,100PRB,30PRB,200PRB(编号都从RB=0开始),其中cell 1~cell 4均被配置使用type-0频域资源分配类型。
所述FDRA域的大小由第一BWP的大小确定。
一种情况中,M个第二服务小区为所有可能调度的服务小区,基于M个第二服务小区的active BWP(激活BWP)的总和确定第一BWP的大小。
在cell 1用于调度cell 1以及cell 1~cell 3组合的search space(搜索空间)内的PDCCH(物理下行控制信道)所承载的第一DCI中,FDRA域对应的频域资源大小(即第一BWP的大小),由包含cell 1以及cell 1~cell 3组合的所有小区的active BWP总和确定,比如50+100+30=180PRB。
类似地,在cell 1用于调度cell 2的search space内的PDCCH所承载的第一DCI中的FDRA对应的频域资源大小(即第一BWP的大小),为100PRB。
在cell 1用于调度cell 3的search space内的PDCCH所承载的第一DCI中的FDRA对应的频域资源大小(即第一BWP的大小),为30PRB。
在cell 4用于调度cell 4的search space内的PDCCH所承载的第一DCI中的FDRA对应的频域资源大小(即第一BWP的大小),为200PRB。
另一种情况中,第一BWP的大小由高层直接配置,例如在cell 1用于调度服务小区的search space内的PDCCH所承载的第一DCI中的FDRA对应的频域资源大小为K个PRB,K为网络配置的正整数。
再一种情况,第一BWP的大小为M个第二服务小区的激活BWP的频域资源的平均值。
比如图4的示例中,M个第二服务小区即cell 1~cell 4,各种第二服务小区组合的total active BWP(总激活BWP)取平均,一般地,近似到十位,即第一BWP的大小为(50+150+130+80)/4=110。
再一种情况,第一BWP的大小为M个第二服务小区的激活BWP的频域资源的总和。M个第二服务小区为同一个小区组的服务小区。
如图4的例子,M个第二服务小区即cell 1~cell 4,即第一BWP的大小为即为50+100+30+200=380PRB。
另一种情况,第一BWP的大小由M个第二服务小区确定,M个第二服务小区由高层信令配置。 例如,第一BWP的大小由cell 1~cell 2确定,即第一BWP的大小为50+100=150PRB。
又一种情况,第一BWP的大小由M个第二服务小区确定,M个第二服务小区是配置的或者激活的服务小区的子集或全集;例如,第一BWP的大小由cell 2确定,cell 2是由cell1调度的配置的或者激活的服务小区中的一个服务小区。
第一RBG的大小至少由第一BWP的大小确定。
以cell1为例,cell1对应的第一BWP的大小为180PRB,RBG size被配置为configuration 2,则查表(如图2所示)可知第一RBG的大小=16。
FDRA域的大小由第一BWP大小和第一RBG的大小确定。即FDRA域的大小等于第一BWP的大小除以第一RBG的大小后向上取值得到的。
以cell1为例,用于调度cell1以及cell1、cell2和cell3组合的search space内的PDCCH所承载的第一DCI中的FDRA域的大小为
Figure PCTCN2021144065-appb-000043
确定指示粒度:一种方式中,所述指示粒度等于第一RBG size(大小),即16。
另一种方式中,所述指示粒度基于所述N个第一服务小区的激活BWP的总和、所述第一BWP的大小以及所述第一RBG的大小确定。
以cell1为例,用于调度cell 1和cell3的2个PDSCH/PUSCH时,其N个第一服务小区的激活BWP的总和为:50+30=80PRBs。假设第一BWP的大小等于180,第一RBG的大小等于16,则所述指示粒度
Figure PCTCN2021144065-appb-000044
这样在保持FDRA域大小不变的情况下,尽可能指示精确,即尽可能小的RBG size,则可以根据实际调度的服务小区的active BWP的总和进行等比例调整。
进一步,所述指示粒度由所述第一值以及第一资源分配类型所对应的预设信息确定,也就是从type0资源配置类型约定的RBG size中找一个最接近且大于等于该计算值的RBG size作为所述指示粒度。以上述示例计算出来的第一值等于7PRB为例来说,通过查表可以得到最接近的值为8,因此确定所述指示粒度为8PRBs。
所述N个数据信道所分别对应的频域资源,由所述FDRA域所指示的频域范围以及所述N个第一服务小区的激活BWP确定。
以cell1为例,用于调度cell1和cell3的2个PDSCH/PUSCH时,对应80PRBs的频域资源;前面已经确定第一DCI中的FDRA域的大小为12,在确定第二RBG size大小(即指示粒度)为8时,可以确定FDRA域中的指示信息的12比特中的前10比特为有效比特,比如表示为0110110100xx。
上述前10bit对应第2,3,5,6,8个RBG。结合所述指示粒度,可以确定第2组RBG包含了8PRB,也就是从第9-16个PRB上传输了数据信道,以此类推。
假设N为2,第i个服务小区为2个服务小区中的cell1,cell1的激活BWP的频域范围为前50的PRB,则cell1的PDSCH/PUSCH占用了第9-24,33-48PRB。若第i个服务小区为cell3,cell3的active BWP的频域范围为30PRB时,cell3的PDSCH/PUSCH占用了第57-64PRB。
下面结合图4,对本方式进行第二种说明:
如图4所示,M等于4,也就是网络侧通过高层信令为终端配置4个第二服务小区(cell 1~cell 4),所述4个第二服务小区属于相同的cell group(如都属于MCG,或者都属于primary PUCCH group/secondary cell group)且通过高层信令为终端配置的服务小区之间的调度关系如图4所示:其中,cell 1~4可以作为单独小区被调度,cell 1可以和cell 2或cell 3一起被调度,cell 2可以和cell 3或cell 1一起被调度。
cell 1~cell 4分别包含的PRB数为50PRB,100PRB,30PRB,200PRB(编号都从RB=0开始),其中cell 1~cell 4均被配置使用type-0频域资源分配类型,且RBG size被配置为configuration 2(RRC配置参数rbg-Size),则
所述FDRA域的大小由第一BWP的大小确定。
一种情况中,M个第二服务小区为所述网络设备第一服务小区组合中的服务小区;所述第一服务小区组合中的服务小区为网络设备为终端设备配置的,且所述第一服务小区组合为等效激活BWP的总和最大的服务小区组合,第一BWP的大小由M个第二服务小区的总和确定。
也就是在cell 1用于调度cell 1以及cell 1~cell 3组合的search space(搜索空间)内的PDCCH(物理下行控制信道)所承载的第一DCI中,FDRA域对应的频域资源大小(即第一BWP的大小)由包含cell 1以及cell 1~cell 3组合的等效active BWP最大的组合确定。以图4为例,在cell 1上调度cell 1以及cell 1~cell 3组合的等效BWP包括:{50,50+100,50+30,100+30},其中,最大的等效BWP为150PRB,所以第一BWP的大小为150PRB。
在cell 4用于调度cell 4的search space内的PDCCH所承载的第一DCI中的FDRA对应的频域资 源大小(即第一BWP的大小),为200PRB。
又一种情况,第一BWP的大小由M个第二服务小区确定,M个第二服务小区是配置的或者激活的服务小区的子集或全集;
第一BWP的大小由M个第二服务小区确定,M个第二服务小区为配置的或者激活的所有服务小区任意组合的子集或全集的等效active BWP最大的组合。例如,cell 1为配置的或者激活的所有服务小区的等效active BWP最大的组合,即cell 1的第一BWP的大小为50PRB。
例如,对于cell 1,M个小区为配置的或者激活的所有第二服务小区即cell 1~cell 3组合的等效active BWP最大的组合,即{50+100,50+30,100+30}中最大的active BWP,即第一BWP的大小为150PRBs。
例如,第一BWP的大小由M个第二服务小区确定,M个第二服务小区高层配置的服务小区和服务小区的任意组合的等效active BWP最大的组合。例如,高层配置cell 1和cell 1~cell 2组合来确定FDRA域的大小,所以,第一BWP的大小为{50,100+50}中最大的值,即150PRB。
另一种情况中,第一BWP的大小由所述网络设备为终端设备配置。例如在一个服务小区用于调度第一服务小区的search space内的PDCCH所承载的第一DCI中的FDRA对应的频域资源大小(即第一BWP的大小)为K个PRB,K为网络配置的正整数。
再一种情况,第一BWP的大小为M个第二服务小区的激活BWP的频域资源的平均值。
比如图4的示例中,M个第二服务小区即cell 1~cell 4,各种第二服务小区组合的total active BWP(总激活BWP)取平均,一般地,近似到十位,即第一BWP的大小为(50+150+130+80)/4=110。
再一种情况,第一BWP的大小为M个第二服务小区的激活BWP的频域资源的总和。M个第二服务小区为同一个小区组的服务小区。
如图4的例子,M个第二服务小区即cell 1~cell 4,即第一BWP的大小为即为50+100+30+200=380PRB。
第一RBG的大小至少由第一BWP的大小确定。
以cell1为例,cell1对应的第一BWP的大小为180PRB,RBG size被配置为configuration 2,则查表(如图2所示)可知第一RBG的大小=16。
FDRA域的大小由第一BWP大小和第一RBG的大小确定。即FDRA域的大小等于第一BWP的大小除以第一RBG的大小后向上取值得到的。
以cell1为例,用于调度cell1以及cell1、cell2和cell3组合的search space内的PDCCH所承载的第一DCI中的FDRA域的大小为
Figure PCTCN2021144065-appb-000045
确定指示粒度:一种方式中,所述指示粒度等于第一RBG size(大小),即16。
另一种方式中,所述指示粒度基于所述N个第一服务小区的激活BWP的总和、所述第一BWP的大小以及所述第一RBG的大小确定。
以cell1为例,用于调度cell 1和cell3的2个PDSCH/PUSCH时,其N个第一服务小区的激活BWP的总和为:50+30=80PRBs。假设第一BWP等于150,第一RBG的大小等于16,则所述指示粒度
Figure PCTCN2021144065-appb-000046
Figure PCTCN2021144065-appb-000047
这样在保持FDRA域大小不变的情况下,尽可能指示精确,即尽可能小的RBG size,则可以根据实际调度的服务小区的active BWP的总和进行等比例调整。
进一步,所述指示粒度由所述第一值以及第一资源分配类型所对应的预设信息确定,也就是从type0资源配置类型约定的RBG size中找一个最接近且大于等于该计算值的RBG size作为所述指示粒度。以上述示例计算出来的第一值等于9PRB为例来说,通过查表可以得到最接近的值为9,因此确定所述指示粒度为9PRBs。
所述N个数据信道所分别对应的频域资源,由所述FDRA域所指示的频域范围以及所述N个第一服务小区的激活BWP确定。
以cell1为例,用于调度cell1和cell3的2个PDSCH/PUSCH时,对应80PRBs的频域资源;前面已经确定第一DCI中的FDRA域的大小为10,且确定第二RBG size大小(即指示粒度)为9时,则FDRA域中的10比特的前9比特为有效比特,对应80PRBs的频域资源。所以,011011011x对应第2,3,5,6,8,9个RBG。
结合所述指示粒度,可以确定第2组RBG包含了9PRB,也就是从第10-18个PRB上传输了数据信道,以此类推。
假设N为2,第i个服务小区为2个服务小区中的cell1,cell1的激活BWP的频域范围为前50的PRB,则cell1的PDSCH/PUSCH占用了cell1的第10-27,37-50PRB,cell3的PDSCH/PUSCH占用了cell3的第1-4,14-30PRB。
可见,通过采用上述方案,可以在第一DCI中调度N个第一服务小区的N个数据信道,从而即可 以保持独立指示的灵活性,并且由于第一DCI的FDRA域的频域大小是基于M个第二服务小区的激活BWP确定的,而M个第二服务小区的激活BWP总和大于等于所述N个第一服务小区的激活BWP总和,因此该第一DCI还可以让多个服务小区共享一个指示域,从而减少FDRA域的指示开销。
