Description

一种PUCCH资源分配方法和一种基站
本申请要求在2019年06月04日提交中国专利局、申请号为201910483035.8、发明名称为“一种PUCCH资源分配方法和一种基站”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本发明涉及通信技术领域,特别是涉及一种PUCCH资源分配方法和一种基站。
背景技术
PUCCH(Physical Uplink Control Channel,物理上行链路控制信道)用于在用户设备与基站同步以后传输上行控制信息,包括:SR(Schedule Request,调度请求)、CSI(Channel State Information,信道状态信息)、ACK(Acknowledgement,肯定应答)/NACK(Negative ACKnowledgment,否定应答)信息等。
在LET(Long Term Evolution,长期演进)系统中,SR和CSI占用的资源都是半静态配置的,即通过RRC(Radio Resource Control,无线资源控制)信令通知进行分配的。在LTE中,ACK/NACK占用的资源由MAC(Media Access Control,媒体介入控制层)通过DCI(Downlink Control Information,下行控制信息)命令动态调度,无需由RRC进行分配。
而在NR(New Radio,新无线)系统中,ACK/NACK资源是在半静态配置的基础上,再通过DCI动态分配的,具体的:RRC信令配置多个资源集,每个资源集又可以分配多组资源,每组资源可以包括时域、频域和码字资源。MAC从RRC信令通知的资源中选择一组,通过MAC的DCI命令动态通知用户设备每次反馈ACK/NACK需要真实占用的资源位置。因此,在LTE系统中对ACK/NACK资源的分配方案不适用于NR系统。

具体实施例
为使本发明实施例的目的、技术方案和优点更加清楚,下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描 述,显然,所描述的实施例是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
参照图1,示出了本发明的一种道PUCCH资源分配方法实施例的步骤流程图,具体可以包括如下步骤:
步骤101,确定PUCCH资源中的剩余资源;
在NR系统中,需要采用PUCCH资源划分给SR、CSI和ACK/NACK。本发明以CSI和SR的资源成功预留为基础,即剩余资源可以是指PUCCH中除去CSI和SR后的资源。
步骤102,根据所述剩余资源,为与所述PUCCH资源对应的小区分配应答资源;
在小区建立时,需要初始化一定数量的ACK/NACK资源。本发明可以是在采用PUCCH资源分配给CSI和SR后,对ACK/NACK进行资源划分,即采用剩余资源,为PUCCH资源对应的小区分配ACK/NACK资源,即应答资源。
步骤103,当用户接入所述小区时,采用所述应答资源承载与所述用户对应的应答信息;所述应答信息包括肯定应答ACK信息和否定应答NACK信息中的至少一种。
在根据剩余资源为小区分配应答资源,用户可以采用应答资源与所述小区传输肯定应答或者否定应答。
在本发明实施例中,通过在PUCCH资源划分给SCI和SR后,采用PUCCH资源中的剩余资源给对应的小区分配应答资源,使得当用户接入小区时,能够采用应答资源与小区传输肯定应答或者否定应答,从而实现提供一种适用于NR系统的PUCCH资源分配方案,在保证用户能够接入小区的同时,SR、CSI和ACK/NACK资源得到充分利用。
在本发明实施例中,所述PUCCH资源包括第一资源和第二资源,所述第一资源位于频带的第一边缘,所述第二资源位于频带的第二边缘,所述第一边缘的频率值小于第二边缘的频率值;所述PUCCH资源对应于多个物理资源块PRB;所述PRB包括与所述第一资源对应于的依次排序的第一PRB,以及与所述第二资源对应于的依次排序的第二PRB;在步骤101之 前,所述方法还包括:获取所述初始信息;所述初始信息包括:调度请求SR和信道状态信息CSI;按照频率值从小到大的次序,将所述第一PRB划分给所述初始信息,以及,按照频率值从大到小的次序,将所述第二PRB划分给所述初始信息。
可以将PUCCH资源划分为两部分,即第一资源和第二资源,其中,第一资源可以位于频带的下边缘即第一边缘,第二资源可以位于频带的上边缘即第二边缘。
PRB是PUCCH资源的物理承载,基于PUCCH资源分为两部分,对应的,PRB也可以分为两部分,即与第一资源对应的第一PRB和与第二资源对于的PRB。
在获取包含有SR和CSI的初始信息后,按照频率值从小到大的次序,将第一PRB划分给初始信息,即建立第一PRB与初始信息的对应关系。当第一PRB耗尽而还有初始信息需要划分资源时,则按照频率值从大到小的次序,将第二PRB划分给初始信息。
在申请实施例中,所述步骤102包括:
子步骤S1021,生成第一格式承载数;所述第一格式承载数为单个所述PRB承载第一格式资源的个数最大值,所述第一格式资源为format1资源;
PUCCH资源可以对应有一个管理站,管理站用于记录与当前PUCCH资源对应的各种参数,例如:与format1资源对应的参数,包括:循环移位间隔CyclicShiftDelta,循环移位个数NofCyclicShift,以及,format1资源占用的符号数。
根据format1占用的符号数和5G标准中的38.211协议,得到时域扩频的可配置个数NofOCC。
第一格式承载数PucchF1ResNum可以通过如下公式生成:
PucchF1ResNum=NofCyclicShift*NofOCC/CyclicShiftDelta
在一种示例中,NofCyclicShift为12,即确定循环位移间隔为12。
子步骤S1022,采用预设的小区配置信息和所述第一个格式承载数,确定所述剩余资源对应的可支持的应答资源套数;每一套应答资源包括第一资源集set0和第二资源集set1;
管理站可以预先设定有小区配置信息,采用小区配置信息和步骤1021 中生成的第一格式承载数,可以确定在PUCCH资源划分给初始信息后,剩余的资源可以支持的应答资源套数。其中,每一套应答资源可以包括第一资源集set0和第二资源集set1。
子步骤S1023,采用所述剩余资源,为所述小区分配与所述可支持的应答资源套数匹配的资源位置。
在确定可支持的应答资源套数后,将剩余资源划分给应答资源,从而实现小区级的应答资源划分。
在本发明的一种实施例中,一个PRB包括多个资源位置;所述小区配置信息包括应答资源期望套数、PUCCH资源对应的PRB总个数、第一资源集占用数、第二资源集占用数,以及,第二格式承载数;其中,所述第一资源集占用数为一个第一资源集占用的资源位置个数、所述第二资源集占用数为一个第二资源集占用的资源位置个数;所述第二格式承载数为一个第二格式资源占用的PRB数量,所述第二格式资源为format3资源;所述子步骤S 1022可以包括:
子步骤S10221,获取资源套数计数值,以及,与所述初始资源占用的PRB数量对应的初始PRB个数;
通过对资源套数技术值的不断递增和执行子步骤S10222-S10227,从而确定出可支持的应答资源套数。
子步骤S10222,当所述资源套数计数值小于所述应答资源期望套数时,采用所述资源套数计数值和所述第一资源集占用数,生成第一资源集占用总数;
子步骤S10223,根据所述第一资源集占用总数和所述第一格式承载数,生成第一资源集PRB占用数;
在本发明的一种实施例中,所述子步骤S10223包括:
子步骤S102231,判断所述初始资源与所述第一资源集是否存在共用的PRB;
子步骤S102232,若所述初始资源与所述第一资源集不存在共用的PRB,采用所述第一资源集占用总数与所述第一格式承载数的商值为所述第一资源集PRB占用数;
子步骤S102233,若所述初始资源与所述第一资源集存在共用的PRB, 则确定在所述共用的PRB中所述第一格式资源占用的资源位置数量为复用资源数;确定所述第一资源集占用总数与所述复用资源数的差值为非复用资源数;采用所述非复用资源数与所述第一格式承载数的商值为所述第一资源集PRB占用数。
子步骤S10224,采用所述第二资源集占用数和所述第二格式承载数,生成第二资源集PRB占用数;
子步骤S10225,计算所述初始PRB个数、所述第一资源集PRB占用数和所述第二资源集PRB占用数之和为当前PRB占用数;
子步骤S10226,当所述当前PRB占用数小于所述PRB总数时,采用预设递增值对所述资源套数计数值进行增数处理,生成新的资源套数计数值;
子步骤S10227,采用所述新的资源套数计数值生成新的当前PRB占用数,直至所述新的当前PRB占用数不小于所述PRB总数时,确定前一个资源套数计数值为所述可支持的应答资源套数。
在本发明的一种实施例中,所述子步骤S10223包括:
子步骤S102231,判断所述初始资源与所述第一资源集是否存在共用的PRB;
子步骤S102232,若所述初始资源与所述第一资源集不存在共用的PRB,采用所述第一资源集占用总数与所述第一格式承载数的商值为所述第一资源集PRB占用数;
子步骤S102233,若所述初始资源与所述第一资源集存在共用的PRB,则确定在所述共用的PRB中所述第一格式资源占用的资源位置数量为复用资源数;确定所述第一资源集占用总数与所述复用资源数的差值为非复用资源数;采用所述非复用资源数与所述第一格式承载数的商值为所述第一资源集PRB占用数。
以下,引用一个示例对子步骤S10221-S10227,以及子步骤S102231-S102233作进一步说明:
小区配置信息包括应答资源期望套数M、PUCCH资源对应的PRB总个数NofPucchPrb、第一资源集占用数NofResPerSet0、第二资源集占用数NofResPerSet1,以及,第二格式承载数NofPrbPerFormat3。
获取资源套数计数值i,和初始PRB个数NofCsiAndSr。
对套数i进行1~M的循环判断,如果支持i套应答资源,则这i套应答资源中第一资源集占用的资源位置总数即第一资源集占用总数NofAckSet0Res通过如下公式计算确定:
NofAckSet0Res=NofResPerSet0*i,
如果对初始信息占用的资源划分之后,SR与set0有共用PRB,且SR在共用PRB中资源位置的最后一个索引为SrLastIndex(0~PucchF1ResNum-1),则这i套应答资源中set0单独占用的PRB个数即第一资源集PRB占用数为:
NofAckSet0Prb=(NofAckSet0Res-(PucchF1ResNum-SrLastIndex-1))/PucchF1ResNum;其中,该公式向上取整。
如果CSI和SR资源划分之后,SR与set0无共用PRB,则i套应答资源中set0单独占用的PRB个数即第一资源集PRB占用数为:
NofAckSet0Prb=NofAckSet0Res/PucchF1ResNum;其中,该公式向上取整。
则i套应答资源中set1占用的PRB个数即第二资源集PRB占用数为:
NofAckSet1Prb=NofPrbPerFormat3*NofResPerSet1*i。
如果(NofCsiAndSr+NofAckSet0Prb+NofAckSet1Prb)大于NofPucchPrb,说明PUCCH资源无法划分给i套应答资源,只能放下i–1套资源,即可支持的应答资源套数N=i–1,获取可支持的应答资源套数N不再继续循环;否则,对i进行加1计算,生成新的资源套数计算值,并重新执行子步骤S10222-S10226。
针对不同的资源集,需要确定对应的起始PRB位置,才能将PUCCH资源划分给对应的资源集。而由于第一资源集的资源格式为format1,所以针对第一资源集,还要生成其对应的初始循环移位信息initialCyclicShift和时域扩频信息timeDomainOCC。
在本发明的一种实施例中,所述子步骤S1023可以包括:
子步骤S10231,确定与所述可支持的应答资源套数对应的目标第一资源集占用总数和目标第二资源集占用总数,以及与所述剩余资源对应的剩余PRB;
在确定可支持应答资源套数N后,可以确定N套应答资源的set0占用的总资源数即目标第一资源集占用总数NofAckSet0Res',N套应答资源的set1占用的总资源数目标第二资源集占用总数NofAckSet1Res'。
子步骤S10232,生成与所述第一资源集对应的初始循环移位信息和时域扩频信息;
以下,引用一个示例对子步骤S10232作进一步说明:
对第一资源集每个中资源i(0~NofAckSet0Res-1)进行循环判断。ResIndex(0~PucchF1ResNum-1)表示第i个资源在当前PRB中的资源索引。
如果SR正好占用了整数个PRB,与set0没有共用的PRB,那么:
ResGlobalIndex=i;ResGlobalIndex表示第一资源集中第i个资源在所有set0占用的PRB中的的资源索引。
如果SR与set0有共用的PRB,则SR对应的最后一个资源的索引为SrLastIndex,此时,ResGlobalIndex为:
ResGlobalIndex=i+SrLastIndex+1;
那么,第一资源集中,第i个资源在当前PRB中的资源索引ResIndex为:
ResIndex=ResGlobalIndex mod PucchF1ResNum;其中,mod为取余运算。
资源索引ResIndex对应的资源位置编号ResPosNum为:
ResPosNum=ResIndex*CyclicShiftDelta。
则initialCyclicShift=ResPosNum mod PucchF1ResNum。
则timeDomainOCC=ResPosNum/PucchF1ResNum;其中,该式向下取整。
子步骤S10233,采用所述剩余PRB确定与所述第一资源集对应的第一起始PRB位置;
子步骤S10234,采用所述第一起始PRB位置、所述循环移位信息和所述时域扩频信息,将所述剩余PRB中划分给与所述目标第一资源集占用总数对应的第一资源集;
在本发明实施例中,所述子步骤S10234包括:
子步骤S102341,判断所述初始PRB个数是否大于所述PRB总数的一半;
子步骤S102342,若所述初始PRB个数不大于所述PRB总数的一半,按照频率值从小到大的次序,以所述第一起始PRB位置为起点,将所述第一PRB划分给所述第一资源集;
子步骤S102343,生成当前第一资源集PRB占用数;
子步骤S102344,当所述当前第一资源集PRB占用数与所述初始PRB个数之和大于所述PRB总数的一半时,按照频率值从大到小的次序,将所述第二PRB划分给所述第一资源集。
子步骤S102345,若所述初始PRB个数大于所述PRB总数的一半,则按照频率值从大到小的次序,以所述第一起始PRB位置为起点,将所述第二PRB划分给所述第一资源集。
以下,引用一个示例对子步骤子步骤S10233-S10234作进一步说明:
对每个第一资源集中的资源i(0~NofAckSet0Res'-1)进行循环判断,先计算前i个第一资源集单独占用的PRB个数Prb set0Num(即不包含和SR共用的PRB)。
如果SR与第一资源集没有共用的PRB,则:
Prbset0Num=ResGlobalIndex/PucchF1ResNum+1;
如果SR与第一资源集存在共用的PRB,则
Prb set0Num=ResGlobalIndex/PucchF1ResNum。
得到Prbset0Num之后,如果SR和CSI占用的PRB个数和前i个第一资源集单独占用的PRB个数不大于PUCCH总个数的一半(NofCsiAndSr+Prb set0Num≤NofPucchPrb/2),即第一资源集中的前i个资源划分在第一PRB,那么:
Startingset0PRB=PrbNum+SrEndPrb;Startingset0PRB为第一资源集的起始PRB位置,SrEndPrb为最后一个SR资源所在的PRB位置。
如果SR和CSI占用的PRB个数和前i个set0资源单独占用的PRB个数大于PUCCH总个数的一半,第一资源集中第i个资源划分在第二PRB。
如果初始PRB个数大于PUCCH总个数的一半,即如果SR和CSI占用的PRB个数小于或等于PUCCH总个数的一半(NofCsiAndSr≤ NofPucchPrb/2)即,即第一资源集是从第一PRB进行划分的,中间出现了翻转,一部分在第一PRB,一部分在第二PRB。记下第一资源集第一次划分在第二PRB时的i值为OverTurnIndex,那么:
FirstUpSet0Prb=PucchUpEndPrb;
UlPrbset0Num=(i–OverTurnIndex)/PucchF1ResNum+1;
其中,FirstUpSet0Prb表示从第二边缘开始划分set0资源是第一资源集所占的第一个PRB,PucchUpEndPrb表示第一个第二PRB,UlPrbset0Num表示划分给第一资源集前i个资源占用的第一PRB个数。
否则,如果初始PRB个数小于PUCCH总个数的一半,即如果SR和CSI占用的PRB个数大于PUCCH总个数的一半,即第一资源集只划分在第二PRB,那么,
如果SR和第一资源集有共用的PRB,
FirstSet0UlPrb=SrEndPrb;
如果SR和第一资源集没有共用的PRB,
FirstSet0UlPrb=SrEndPrb–1。
其中,SrEndPrb表示最后一个SR资源所在的PRB位置。
由于第一资源集只划分在第二PRB,前i个资源在PUCCH上半部分单独占用的PRB个数与前i个set0资源单独占用的PRB个数PrbNum相同,即,
UlPrbset0Num=Prbset0Num。
那么,第一资源集的第i个资源在第一PRB划分时时,如果SR与第一资源集没有共用的PRB,则:
Startingset0PRB=FirstSet0UlPrb+1-UlPrbset0Num;
如果SR与第一资源集存在共用PRB,则:
Startingset0PRB=FirstSet0UlPrb–UlPrbset0Num。
采用所述Startingset1PRB、initialCyclicShift和timeDomainOCC,将PUCCH资源对应的PRB分配给第一资源集。
子步骤S10235,根据所述第一资源集存储的资源位置,确定与所述第二资源集对应的第二起始PRB位置;
子步骤S10236,采用所述第二起始PRB位置和所述第二格式承载数, 将所述剩余PRB中划分给与所述目标第二资源集占用总数对应的第二资源集。
在申请的一种实施例中,所述子步骤S10236可以包括:
子步骤S102361,生成当前第一资源集PRB占用数;
子步骤S102362,判断所述初始PRB个数与所述当前第一资源集PRB占用数之和是否大于所述PRB总数的一半;
子步骤S102363,若所述初始PRB个数与所述当前第一资源集PRB占用数之和不大于所述PRB总数的一半,则按照频率值从小到大的次序,以所述第二起始PRB位置为起点,将所述第一PRB划分给所述第二资源集;
子步骤S102364,生成当前第二资源集PRB占用数;
子步骤S102365,当所述初始PRB个数、所述当前第一资源集PRB占用数、所述当前第二资源集PRB占用数之和大于所述PRB总数的一半时,按照频率值从大到小的次序,将所述第二PRB划分给所述第一资源集。
子步骤S102366,若所述初始PRB个数与所述当前第一资源集PRB占用数之和大于所述PRB总数的一半,则以第二起始PRB位置为起点,将所述第二PRB划分给所述第二资源集。
以下,引用一个示例对子步骤S10235-S10236作进一步说明:
对每个资源i(0~NofAckSet1Res'-1)进行循环判断:
先计算前i个第二资源集单独占用的PRB个数Prbset1Num:
Prb set1Num=(i+1)*NofPrbPerFormat3;
如果SR、CSI和第一资源集占用的PRB个数和前i个第二资源集单独占用的PRB个数不大于PUCCH总个数的一半(NofCsiAndSr+NofAckSet0Prb+PrbNum≤NofPucchPrb/2),即第二资源集前i个划分在第一PRB,那么,
Startingset1PRB=Ack0EndPrb+1+i*NofPrbPerFormat3;
其中,Ack0EndPrb表示第一资源集占用的PRB位置。
否则,如果SR、CSI和第一资源集占用的PRB个数和前i个第二资源集单独占用的PRB个数大于PUCCH总个数的一半,则第i个资源在PUCCH上半部分排布。
此时,如果SR、CSI和第一资源集占用的PRB个数小于等于PUCCH 总个数的一半(NofCsiAndSr+NofAckSet0Prb≤NofPucchPrb/2),即第一资源集是一开始是划分在第一PRB,中间出现了翻转,一部分划分在第一PRB,另一部分划分在第二PRB。记下第二资源集第一次翻转到PUCCH上半部分时的i值为OverTurnIndex'。那么,
UlPrbset1Num=(i–OverTurnIndex+1)*PucchF3ResNum;
startingPRB=PucchUpEndPrb+1–UlPrbset1Num;
其中,PucchUpEndPrb表示PUCCH上半部分资源的上边缘PRB,UlPrbset1Num表示第二资源集中前i个资源在单独占用的第一PRB个数。
否则,如果SR、CSI和第一资源集占用的PRB个数大于PUCCH总个数的一半,即第二资源集只划分在第二PRB,那么,
UlPrbset1Num=(i+1)*PucchF3ResNum;
Startingset1PRB=Ack0EndPrb–UlPrbset1Num。
采用所述Startingset1PRB,将PUCCH资源对应的PRB分配给第二资源集。
