Abstract
一种资源分配指示域的确定方法及终端设备、网络设备。该方法包括:终端设备接收网络设备发送的下行控制信息DCI,所述DCI用于调度N个信道,所述N个信道位于M个服务小区或服务小区组,N、M为正整数,M小于或等于N;其中,所述DCI包含用于指示所述N个信道的资源的资源分配指示域;所述资源分配指示域对应的比特数为第一比特数。本方案采用下行控制信息DCI包含的资源分配指示域,指示位于一个或多个服务小区和/或服务小区组的信道的资源,从而可以采用一个DCI调度网络设备为终端设备配置的一个或多个服务小区的信道,减少信令开销、提升DCI利用率。
Description
本发明涉及通信技术领域,尤其涉及一种资源分配指示域的确定方法及终端设备、网络设备。
在NR(New Radio,新空口)无线接入系统中,上行传输和下行传输均支持两种频域资源分配类型:Type 0频域资源分配和Type 1频域资源分配。网络侧通过高层参数(如:resourceAllocation)来配置终端设备所使用的频域资源分配类型,如:Type 0频域资源分配、Type 1频域资源分配、或动态切换。当配置为动态切换时,网络侧通过DCI(Downlink Control Information,下行控制信息)中的FDRA(Frequency domain resource assignment,频域资源分配指示域)来指示终端设备所使用的频域资源分配的类型。
若用于调度的DCI中没有配置BWP(Bandwidth Part,带宽部分)指示域,或者终端设备不支持基于DCI的BWP改变,那么频域资源分配类型对应的RB(Resource Block,资源块)索引是在终端设备对应的激活BWP中确定的。若终端设备支持基于DCI的BWP改变,且用于调度的DCI中配置了BWP指示域,那么频域资源分配类型对应的资源块RB索引是基于DCI中的BWP指示域指示的BWP确定的。因此,终端设备需要先通过PDCCH(Physical Downlink Control Channel,物理下行控制信道)检测确定BWP,再确定在BWP中的频域资源分配。
而NR系统支持终端设备在网络侧配置的SSS(Search Space Sets,搜索空间集合)中进行PDCCH盲检。之所以谓之“盲检”,是因为终端设备在检测到PDCCH承载的DCI之前并不知道DCI的格式等信息。因此,终端设备需要使用一些固定的DCI size(DCI大小)对搜索空间集合中的候选PDCCH进行盲检。为了降低终端设备盲检PDCCH的复杂度,NR规定在进行完协议定义的DCI大小对齐(DCI size alignment)步骤之后,终端设备不期待总的DCI size大于4,以及C-RNTI(Cell-Radio Network Temporary Identifier,小区无线网络临时标识)加扰的总的DCI size大于3。
由于终端设备只是尝试使用一些固定的DCI size来对PDCCH进行检测,这就需要终端设备在PDCCH盲检之前,知道不同DCI格式的DCI size是多少。即,终端设备在PDCCH盲检之前,需要知道DCI中所包含的每个信息域,比如FDRA域(Frequency domain resource assignment,频域资源分配)指示域,所包含的比特数是多少。

请参看图1,其示出了本申请实施方式应用的无线通信系统100。该无线通信系统100包括:网络设备110,以及位于该网络设备110覆盖范围内的至少一个用户设备120。该网络设备110发送触发信令或DCI给该用户设备120,该用户设备120根据触发信令或DCI发送ACK/NACK反馈信息给该网络设备。
该无线通信系统100可以包括多个网络设备并且每个网络设备的覆盖范围内可以包括其它数量的用户设备,本申请实施方式对此不做限定。
其中,该网络设备110可以为特定的地理区域提供通信覆盖,并且可以与位于该覆盖区域内的用户设备(例如UE)进行通信。该网络设备100可以是GSM系统或CDMA系统中的基站(Base Transceiver Station,BTS),也可以是WCDMA系统中的基站(NodeB,NB),还可以是LTE系统中的演进型基站(Evolutional Node B,eNB或eNodeB),或者是云无线接入网络(Cloud Radio Access Network,CRAN)中的无线控制器,或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备、5G网络中的网络侧设备或者未来演进的公共陆地移动网络(Public Land Mobile Network,PLMN)中的网络设备等。

本申请以下实施方式将详细阐述,在一个DCI调度一个或多个服务服务小区和/或服务小区组的信道的过程中,终端设备是如何确定所述信道的资源的,更进一步的,终端设备在PDCCH盲检时,是如何确定资源分配指示域所需要的比特数。尤其是一个DCI调度多个服务小区和/或服务小区组的信道的情形,由于被调度的多个服务小区和/或服务小区组的数量是不确定的,且不同服务小区上的激活BWP的大小(即激活BWP中包含的物理资源块PRB数)或者激活BWP组的大小也是不尽相同的。因此,当一个DCI调度多个服务小区和/或服务小区组的信道,如何确定或使用DCI中的资源分配指示域(包括频域资源分配指示域和时域资源分配指示域)是一个亟待解决的问题。
在本申请以下实施方式中,以DCI中的FDRA(Frequency domain resource assignment,频域资源分配)指示域进行举例,说明在一个DCI调度多个服务服务小区和/或服务小区组的情况下,终端设备如何确定DCI中FDRA域的大小,但是本申请的方法及其设备并不限于确定FDRA域的大小,DCI中和BWP size、高层配置参数相关的指示域如TDRA(Time domain resource assignment,时域资源分配指示域)等都适用。在本申请的实施例中的资源,均可包含时域资源或频域资源。需说明的是,NR支持的Type 0频域资源分配类型,其资源分配的粒度为RBG(Resource Block Group,资源块组),RBG为一系列连续的虚拟RB(Resource Block,资源块)的组合,每个RBG包括的虚拟RB的数量根据BWP的大小以及RRC(Radio Resource Control,无线资源控制)信令配置参数rbg-Size确定。NR支持的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(RBstart)和RB数量(LRBs)进行联合编码。
终端设备在进行PDCCH盲检时,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FDRA域为例,其比特数的确定方式如下:
如果只配置了type 0频域资源分配类型,则指示域包含N
RBG比特;其中,N
RBG为一个BWP所包含的总的RBG的数量;
为激活BWP包含的RB数,该公式中采用下行激活BWP为例进行说明,可以理解的是上行激活BWP包含的RB数同样也可应用该公式。
如果同时配置了type 0和type 1,则指示域包含:

具体而言,本申请实施方式一提供以下两种方案确定所述第一比特数或所述第四比特数:
方案一
在一些实施例中,所述第一比特数根据以下至少之一确定:第一服务小区的激活BWP的大小;所述第一服务小区的激活BWP对应的资源分配类型;所述第一服务小区的激活BWP对应的资源调度粒度。和/或,若所述第一服务小区与所述子域对应,则所述第四比特数根据以下至少之一确定:所述第一服务小区的激活BWP的大小;所述第一服务小区的激活BWP对应的资源分配类型;所述第一服务小区的激活BWP对应的资源调度粒度。其中,所述第一服务小区为所述终端设备所检测的物理下行控制信道PDCCH对应的小区。即,对于第四比特数而言,若所述第一服务小区与所述子域对应,则所述子域才可根据所述第一服务小区的激活BWP对应的资源分配类型、资源调度粒度中至少之一确定;若第一服务小区与所述子域不对应,则所述子域的比特数不可根据所述第一服务小区的激活BWP对应的资源分配类型、资源调度粒度中至少之一确定。
换而言之,所述终端设备为所述第一服务小区检测所述DCI。又或者说,网络设备为第一服务小区的搜索空间集合配置了所述DCI。又或者说,所述DCI所在的候选PDCCH(PDCCH candidate)是根据第一服务小区确定的。由此可见,第一服务小区为被调度小区(scheduled cell),而非调度小区(scheduling cell)。
本申请的实施方式中提及的检测亦可包含监测之意。
在一些实施例中,可由终端设备根据第一服务小区的激活BWP的大小、所述第一服务小区的激活BWP对应的资源分配类型、资源调度粒度中至少之一确定第一比特数或第四比特数。
换而言之,在方案一中,所述第一比特数对应的第一服务小区是FDRA域对应的所有服务小区中被所述终端设备检测PDCCH的服务小区。所述第四比特对应的第一服务小区是所述子域所对应的所有服务小区中被所述终端设备检测PDCCH的服务小区。
总体而言,方案一的实现过程相对简单,可最大化复用现有技术,但由于终端设备在不同的被调度小区中检测DCI时的DCI size不相同,因此只能在其中某个小区中检测到调度N个小区的DCI,PDCCH位置不灵活,更容易造成PDCCH阻塞(PDCCH blockage)。
例如:请参看图3,为本申请实施方式一中服务小区或服务小区组的一个具体示例。网络设备通过高层信令为终端设备配置4个服务小区(cell 1~cell 4)。所述4个服务小区属于相同的cell group(如都属于MCG,或者都属于primary PUCCH group或secondary cell group)且通过高层信令为终端设备配置的服务小区之间的调度关系如图3所示:cell 1~cell4均可以单独被调度,cell 1可以与cell 2或cell 3一起被调度,cell 2可以与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),且cell 1~cell 4均被配置使用type-0资源分配类型,RBG size被配置为configuration 2(RRC配置参数rbg-Size)。因此cell 1~cell4上分别使用的RBG size为8RPB、16PRB、4PRB、16PRB。进一步的,cell 1~cell 4单独调度所需要的比特数分别为
在上述方案一种,若第一服务小区为cell 1,即终端为了cell 1检测PDCCH,则所述DCI中的FDRA域对应的的第一比特数根据cell 1上的激活BWP大小、cell 1上的激活BWP对应的资源分配类型resourceAllocation、资源调度粒度rbg-Size确定,即为7比特。若第一服务小区为cell 4,即终端为了cell 4检测PDCCH,则所述DCI中的FDRA域对应的的第一比特数根据cell 4上的激活BWP大小、cell 4上的激活BWP对应的resourceAllocation、rbg-Size确定,即为13比特。
或者,若所述cell 1和cell 2为所述相同的cellgroup中的一个子服务小区组,cell 3和cell 4为所述相同的cellgroup的也为另一个子服务小区组,所述Q个信道位于的服务小区组为第一服务小区cell 1和第二服务小区cell 2(即所述一个子服务小区组中),则FDRA域中与所述Q个信道对应的子域的第四比特数也是根据第一服务小区cell 1上的激活BWP大小、对应的资源分配类型resourceAllocation、资源调度粒度rbg-Size确定,即为7比特。
方案二
在一些实施例中,所述第一比特数根据至少一个第二比特数中的最大值或最小值确定;和/或,所述第四比特数是根据与所述子域对应的所述至少一个第二比特数中的最大值或最小值确定。其中,所述第二比特数是第一类服务小区中每一服务小区的信道资源分配所需的比特数。
其中,本申请所提及的服务小区和/或服务小区组的信道资源分配所需的比特数是指为服务小区和/或服务小区组的信道指示资源所需要的指示域中的比特数。服务小区和/或服务小区组的信道资源分配所需的比特数,也可以表述为,为服务小区和/或服务小区组的信道分配资源所需的比特数。
在一些实施例中,每个所述第二比特数为根据每个所述第一类服务小区中每个服务小区的激活BWP的大小、第二服务小区的激活BWP对应的资源分配类型resourceAllocation参数、资源调度粒度rbg-Size中的至少之一确定的。
具体而言,其中的第一类服务小区可以有以下几种范围:
范围1:第一类服务小区包括网络设备通过高层信令配置给终端设备的所有服务小区。
在一些实施例中,所述第一比特数对应的所述第一类服务小区包括网络设备通过高层信令给所述终端设备配置的所有服务小区;所述第四比特数对应的所述第一类服务小区包括网络设备通过高层信令给所述终端设备配置的所有服务小区中与所述子域对应的服务小区。
在范围1中,在网路设备配置的所有服务小区中,选取第二比特数中的最大值或最小值作为第一比特数或第四比特数,该方案简单,但是DCI size也最大或最小,因此资源利用率相对较低。
范围2:第一类服务小区包括网络设备配置或者由协议约定第一服务小区组中的所有服务小区。
在一些实施例中,所述第一比特数对应的所述第一类服务小区包括所述第一服务小区组中的所有服务小区;所述第四比特数对应的所述第一类服务小区包括网络设备配置或者协议约定的给所述终端设备的第一服务小区组中与所述子域对应的所有服务小区。
在一些实施例中,所述第一服务小区组包含第一服务小区,或者,所述第一服务小区组为与所述第一服务小区对应的服务小区组,其中,所述第一服务小区为所述终端设备所检测的物理下行控制信道PDCCH对应的小区。其中,与所述第一服务小区对应的服务小区组是指与所述第一服务小区存在某种对应关系,该对应关系可以是网络配置的,也可以是协议约定的,例如:该对应关系是可与第一服务小区被同一个DCI调度的服务小区组。
在一些实施例中,所述第一服务小区组包括但不限于主小区组(Master cell group,MCG)、辅小区组(Secondary cell group,SCG),PUCCH组(PUCCH group),还可泛指任何服务小区的组合。
在范围2中,实现方式相较于范围1中的实现方式较为复杂,但是DCI size较小,因此资源利用率相对较高。
范围3:第一类服务小区包括第一服务小区以及和第二类服务小区。
在一些实施例中,所述第一服务小区为所述终端设备所检测的物理下行控制信道PDCCH对应的小区,所述第二类服务小区中每个服务小区的信道与所述第一服务小区的信道可被同一下行控制信息DCI调度。对于第四比特数而言,若所述第一类服务小区中包含的这些小区与所述子域对应, 如,所述第一服务小区与所述子域对应,则所述第四比特数可根据与所述子域对应的服务小区确定其比特数。
在范围3中,相较于上述范围1和范围2中实现方式而言,实现方式最复杂,但DCI size最小,资源利用率最高。
总体而言,方案二按照需要的频域资源分配比特数中最大值或者最小值来确定第一比特数或第四比特数,资源分配比较灵活,且对于不同的被调度小区,调度N个小区的DCI不管在哪个小区上检测,DCI size都相同,即都可能检测到,网络设备(如基站)发送DCI时,在一些实施例中候选PDCCH(PDCCH candidate)比较灵活。
例如,请继续参看图3,对上述方案二进行举例说明。其中,网络侧对服务小区的配置、调度关系、资源分配类型、服务小区激活BWP所包含的PRB数、RBG size都和上述方案一中的举例保持一致。若第一服务小区为cell 1,即终端为了cell 1检测PDCCH,则所述FDRA域对应的的第一比特数或所述FDRA域的子域对应的的第四比特数为:
对于范围1:第一类服务小区包括网络设备通过高层信令配置的所有的服务小区为cell 1~cell 4,cell 1~cell 4分别对应的第二比特数为7、7、8、13,则第一比特数为其中的最大值13比特,或者最小值7比特。若所述Q个信道位于小区cell 3,则与第四比特数对应的第一类服务小区为cell 3,即,第四比特数为8。
对于范围2:cell 1~cell 4在均属于同一小区组,所以第一类服务小区同样也包括cell 1~cell 4,cell 1~cell 4分别对应的第二比特数为7、7、8、13,则第一比特数为其中的最大值13比特,或者最小值7比特。若所述Q个信道位于小区cell 3,则与第四比特数对应的第二服务小区为cell 3,即,第四比特数为8。
对于范围3:若第一服务小区为cell 1。则第一类服务小区包括第一服务小区cell 1,以及可以与第一服务小区cell 1同时调度的服务小区cell 2和cell 3,即椭圆框1内包括的所有小区cell 1~cell 3。cell 1~cell 3分别对应的第二比特数为7、7、8。第一比特数为其中的最大值8比特,或者最小值7比特。若第一服务小区为cell 3,则需要考虑的是椭圆框2内的小区,即第一服务小区cell 3以及可以和cell 3同时调度的小区cell 1和cell 2。
还是假设第一服务小区为cell 1。若所述Q个信道位于同一服务小区组,假设该服务小区组包括cell 1与cell 2,则第四比特数对应的第一类服务小区包括cell 1与cell 2,取其中最大值为7比特,即此时第四比特数为7比特。假设该服务小区组包括cell 3和cell 4,则第四比特数对应的第一类服务小区包括cell1和cell 3,取其最大值比特数8为第四比特数。
本申请实施方式一提供的资源分配指示域的确定方法中,还需对资源分配指示域进行解读。所述FDRA域用于指示N个信道的资源,或者所述子域用于指示Q个信道的资源。终端设备根据以下至少之一对所述FDRA域或子域进行解读:每个信道所在的服务小区的激活BWP的大小、激活BWP对应的资源分配类型resourceAllocatio、激活BWP对应的资源分配粒度rbg-Size、所述FDRA域或子域的比特数、所述FDRA域或子域的取值。具体而言包括以下两种解读方式:
解读方式1:
在一些实施例中,请继续参看图2,所述方法还包括:S220,在所述第一比特数或第四比特数小于信道资源分配所需的比特数的情况下,终端设备在所述资源分配指示域或子域中添加第一值,。具体包括:
在所述第一比特数小于第三比特数的情况下,所述终端设备在所述资源分配指示域的前面添加第一值,添加所述第一值后的所述资源分配指示域比特数达到所述第三比特数的大小,其中,所述第三比特数是所述N个信道中的一个信道资源分配所需的比特数;或者
在所述第四比特数小于第五比特数的情况下,所述终端设备在所述子域的前面添加所述第一值,添加所述第一值后的所述子域的比特数达到所述第五比特数的大小,其中,所述第五比特数是所述所述Q个信道中的一个信道资源分配所需的比特数。
在一些实施例中,所述第三比特数是终端设备根据每个信道所在的服务小区的激活BWP的大小、激活BWP对应的资源分配类型resourceAllocatio、激活BWP对应的资源分配粒度rbg-Size中的至少之一得到的。
在一些实施例中,所述方法还包括:S230,在所述第一比特数或第四比特数大于或等于信道资源分配所需的比特数的情况下,所述终端设备使用所述资源分配指示域或子域中的最高位或最低位解读所述资源分配指示域或子域。具体包括:
在所述第一比特数大于所述第三比特数X的情况下,所述终端设备使用所述资源分配指示域的最低X位或者最高X位来解读所述资源分配指示域;其中,所述第三比特数X是为所述N个信道中的一个信道资源分配所需的比特数,X为整数;或者
在所述第四比特数大于所述第五比特数Y的情况下,所述终端设备使用所述子域的最低Y位或者最高Y位来解读所述子域;其中,所述第五比特数Y是所述Q个信道中的一个信道资源分配所需的比特数,Y为整数。
其中,若所述第一比特数或第四比特数等于信道资源分配所需的比特数,所述资源分配指示域的最低X位于最高X位完全重合;所述子域的最低Y位和最高Y位完全重合。
解读方式1的资源分配相对灵活。
解读方式2:
在一些实施例中,请参看图4,所述方法还包括:
S240,所述终端设备根据所述资源分配指示域确定第一信道的资源分配结果,并根据所述资源分配结果确定所述N个信道或所述Q个信道中的其他信道的资源分配;其中,所述第一信道为所述第一服务小区对应的信道,或者,为所述第一类服务小区的信道中资源分配所需比特数最小或最大的信道。
其中,所述第二类服务小区中每个服务小区的信道与所述第一服务小区的信道可被同一下行控制信息DCI调度。
例如:所述其他信道与第一信道相同的RBG(Resource Block Group,资源块组)集合或者PRB(Physical Resource Block,物理资源块)集合,所述“相同”的含义可以理解为:相对于各自的激活BWP的第一个RBG/PRB具有相同偏移量(offset)的RBG和PRB;所述RBG size在所述其他信道和第一信道中相同或不同。其中,RBG为业务信道资源分配的资源单位,由一组RB(Physical Resource Block,资源块)组成。
又例如:所述其他信道的RBG集合和PRB集合为相对于第一信道的RBG集合和PRB集合偏移一定的offset确定的。
解读方式2相对简单,但是灵活性相对较差。
例如,请参看图3,例如,对上述解读方式1和解读方式2进行举例说明。其中,网络侧对服务小区的配置、调度关系、资源分配类型、服务小区激活BWP所包含的PRB数、RBG size都和上述方案一、方案二中的举例保持一致。
对于解读方式1:
假设第一比特数为7比特,cell 1~cell 4的信道资源调度所需的第三比特数分别为7、7、,8、13比特,FDRA域指示为1001001。则cell 1和cell 2的信道的RBG按照1001001解读即可,而cell 3在需最高位前添0,即按照01001001解读,cell 4在最高位前添00000,即按照00000 1001001解读。假设第四比特数为4比特,FDRA域的子域指示为1001,假设有个两个信道位于cell 1和cell 2中(即Q=2,两个信道位于同一子服务小区组,即包含cell 1和cell 2的子服务小区组),cell 1和cell 2的两个信道资源调度所需的第三比特数分别为7、7比特,则需在该子域的最高位钱添加0,按照0001001,0001001解读。
假设第一比特数为13比特,cell 1~cell 4的第三比特数分别为7,7,8,13比特,FDRA域指示为1001 1001 1001 1。则cell 4的信道的RBG即按照1001 1001 1001 1解读,而cell 1~3按照1001 1001 1001 1的最高7或8位,或者最低7或8位解读。假设第四比特数为13比特,FDRA域的子域指示为1001 1001 1001 1,假设有个两个信道位于cell 1和cell 2中(即Q=2,两个信道位于同一子服务小区组,即包含cell 1和cell 2的子服务小区组),cell 1和cell 2的两个信道资源调度所需的第三比特数分别为7,7比特,则cell 1和cell 2的两个信道按照1001 1001 1001 1中的最高7位,或者最低的7位进行解读。
对于解读方式2:
假设所述DCI调度cell 1+cell 4的小区组合,其中cell 1为第一服务小区,FDRA域指示出cell 1使用前5个RBG,则cell 4也解读为使用前5个RBG。
假设FDRA域中的一个子域调度cell 1+cell 4的小区组合,其中cell 1为第一服务小区,该子域指示cell 1使用前5个RBG,则cell4也解读为使用前5个RBG。
