Description
本申请要求于2020年4月10日提交国家知识产权局、申请号为202010281207.6、发明名称为“一种资源指示方法及相关设备”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。
本申请实施例涉及通信技术领域,尤其涉及一种资源指示方法及相关设备。
混合自动重传请求(hybrid automatic repeat request,HARQ)是一种结合了前向纠错(Forward Error Correction,EFC)技术与自动重传请求(Automatic Repeat Request,ARQ)技术,用于进行差错控制,从而确保通信质量的重传方法。
以接收端是用户设备(user equipment,UE),发送端是基站为例。基站可以采用以下方式向UE指示用于反馈HARQ-ACK的时隙(slot)和物理上行控制信道(Physical Uplink Control Channel,PUCCH)资源。其中,基站可以向UE发送下行控制信息(Downlink Control Information,DCI)。该DCI中包括K1。UE可以根据DCI中的K1的值确定反馈HARQ-ACK的slot。该DCI中还包括PUCCH资源的指示信息,该指示信息包括PUCCH资源的标识ID、该PUCCH资源在上述slot的起始位置,以及该PUCCH资源的长度。UE可以根据该指示信息确定用于反馈HARQ-ACK的PUCCH资源。
其中,当需要反馈多个HARQ-ACK时,多个HARQ-ACK信息比特就组成了一个HARQ-ACK码本(codebook)。在Rel-15标准中,HARQ-ACK码本都是以slot为单位进行处理的,即一个slot传输一个HARQ-ACK码本。每个slot包括14个符号。其中,上述DCI可以包括DCI格式1_0(DCI format 1_0)和DCI格式1_1(DCI format 1_1)。DCI 1_0和DCI 1_1均可以适用于Rel-15标准中的HARQ-ACK传输方案。
Rel-16标准提出一种子时隙(sub-slot)的方案。该方案中可以将一个slot分为好几部分,如可以将一个slot分为2个sub-slot,每个sub-slot包括7个符号;或者,可以将一个slot分为7个sub-slot,每个sub-slot包括2个符号。在该sub-slot的方案中,可以以sub-slot为单位反馈HARQ-ACK码本。即一个sub-slot可传输一个HARQ-ACK码本。但是,DCI 1_0并不适用于sub-slot的HARQ-ACK传输方案。
发明内容
本申请提供一种资源指示方法及相关设备,使得终端设备可以根据DCI中指示的PUCCH资源,通过至少一个子时隙的PUCCH资源上发送HARQ-ACK,从而提高了终端设备响应DCI的灵活性。
为实现上述技术目的,本申请采用如下技术方案:
第一方面,本申请提供一种资源指示方法,该方法可以应用于终端设备,该方法可以包括:终端设备可以接收来自网络设备的DCI,DCI用于指示终端设备传输HARQ-ACK的时隙。终端设备接收到上述DCI之后,可以在时隙的至少一个子时隙 的PUCCH资源上发送上述HARQ-ACK,其中,时隙包括至少两个子时隙。

图3中示出的设备结构并不构成对UE的限定,可以包括比图示更多或更少的部件,或者组合某些部件,或者不同的部件布置。尽管未示出,UE还可以包括电池、摄像头、蓝牙模块、全球定位系统(Global Position System,GPS)模块、显示屏等,在此不再赘述。
以下将对本申请实施例涉及的术语进行介绍。
(1)下行控制信息DCI:由下行物理控制信道PDCCH承载,网络设备(如,基站)发给终端设备(如,UE)的控制信息,DCI中可以包括上下行资源分配、HARQ信息、功率控制等信息。本申请实施例中DCI的格式包括DCI 1_0,DCI 1_1和DCI 1_2 等。
其中,DCI 1_0中每个域的大小是固定的,即不能通过无线资源控制(Radio Resource Control,RRC)来配置某个域的大小。也就是说,DCI 1_0的总比特数是固定的,且每个域的比特数也是固定的。例如,DCI 1_0中的PDSCH到HARQ反馈定时指示(PDSCH-to-HARQ_feedback timing indicator),这个域的大小是固定的3比特。需要说明的,如果通过RRC配置其它DCI格式中某个域的大小时,则可以向终端设备发送DCI 1_0,因为DCI 1_0不会受到RRC配置的影响。这样,终端设备接收到DCI 1_0,可以通过DCI 1_0回退到RRC配置DCI信息之前的状态。因此,DCI 1_0也可以被称为回退DCI。
其中,DCI 1_1中某些域的大小会受到RRC配置的影响,即DCI 1_1中某些域的大小是可变的。例如,DCI 1_1中的PDSCH到HARQ反馈定时指示,这个域的大小可以是0比特或者1比特或者2比特或者3比特。也就是说,DCI 1_1的大小会因为RRC的配置而改变。
(2)时隙:本申请实施例中,一个时隙slot包含的正交频分复用(Orthogonal frequency-division multiplexing,OFDM)符号数为14个,其符号的编号可以是0到13。其中,在时域上,这些符号是连续的。本申请实施例中,时隙中的一个符号可以是一个PUCCH资源。
(3)子时隙(sub-slot):一个时隙可以被分为多个部分,每个部分都是一个sub-slot。如图4中的(a)和(b)所示,其中,图4中(a)表示7符号的sub-slot,则一个时隙可以被分为两个sub-slot;图4中(b)表示2符号的sub-slot,则一个时隙可以被分为七个sub-slot。应当理解,子时隙和时隙的主要区别在于包含的符号个数不同,子时隙也可以用其它术语来表述,本发明不做限定。特别的,如果子时隙的长度等于2,子时隙也可以称为2符号的时隙;如果子时隙的长度等于7,子时隙也可以称为7符号的时隙。本发明中,还是以子时隙为例进行说明。
(4)码本:终端设备接收到来自网络设备的DCI,则终端设备向网络设备发送HARQ-ACK。当终端设备需要向网络设备反馈多个HARQ-ACK的比特时,这些HARQ-ACK比特可以组成一个码本。也就是说,码本是包括多个HARQ-ACK比特信息。本申请实施例中,时延性不同的业务可以对应不同的码本,并且不同的码本之间可以有不同的优先级。例如,高时延的业务(例如URLLC)对应高优先级的码本,时延要求不高的业务(例如eMBB)对应低优先级的码本。
(5)PUCCH资源:一个PUCCH资源包括起始物理资源块(PRB:physical resource block),PRB的个数,起始符号索引(starting symbol index)以及符号个数等。
一般而言,基站可以通过物理下行控制信道(Physical Downlink Control Channel,PDCCH)向UE发送下行控制信息DCI。当基站向UE发送DCI 1_0时,DCI 1_0指示物理下行共享信道(Physical downlink shared channel,PDSCH)和传输HARQ-ACK之间的时隙间隔。例如,DCI 1_0中的PDSCH到HARQ反馈定时指示域指示该时隙间隔为K1,则UE可以根据DCI 1_0中指示的PDSCH和HARQ-ACK之间的时隙间隔(即K1)确定传输HARQ-ACK的时隙。由此,UE可以在该时隙的PUCCH资源上向基站传输HARQ-ACK。
示例性的,基站向UE发送DCI 1_0,UE接收到PDSCH,PDSCH在时隙slot n结束。如图5所示,为UE确定向基站传输HARQ-ACK的时隙的示意图。假设DCI 1_0中的K1为4,则UE可以根据DCI 1_0中的K1确定出向基站发送HARQ-ACK的时隙为slot n+K1,即slot n+4。因此,UE在时隙slot n+4上传输HARQ-ACK。
可以理解的,当UE确定传输HARQ-ACK的时隙之后,还需要确定出在该时隙上传输HARQ-ACK使用的PUCCH资源,然后在该时隙的PUCCH资源上传输HARQ-ACK。其中,DCI 1_0中可以包括PUCCH资源索引,UE可以根据PUCCH资源索引确定出传输HARQ-ACK使用的PUCCH资源。
具体地说,UE可以根据上行控制信息(Uplink control information,UCI)的比特数确定出传输PUCCH资源的资源集,进而UE在该资源集中,根据DCI 1_0中指示的PUCCH资源索引确定PUCCH资源。
示例性的,如图6所示,为UE确定传输HARQ-ACK的PUCCH资源的方法的流程图。该方法可以包括步骤601和步骤602。
步骤601:UE根据UCI的信息比特数确定一个PUCCH资源集。
其中,UCI是UE向基站发送的上行控制信息。当UE向基站发送UCI时,UE可以获取UCI中的信息比特数。例如,UE接收到来自基站的DCI,当UE响应于DCI向基站传输UCI信息,则UE生成UCI之后确定出UCI的信息比特数。
需要说明的,UE处于基站通信的小区范围时,UE可以使用基站的PUCCH小区配置参数(PUCCH-ConfigCommon)。由于PUCCH小区配置参数中仅配置一个PUCCH资源集,则UE使用PUCCH小区配置参数配置的PUCCH资源集即可,则不需要通过UCI的信息比特数确定PUCCH资源集。
可以理解的,当UE接收到来自基站的PUCCH配置参数(PUCCH-Config),则UE可以根据UCI的信息比特数确定出PUCCH配置参数中的一个PUCCH资源集。
其中,UCI中的信息比特数不同,则UE可以选择不用的PUCCH资源集。
示例性的:OUCI表示UCI中的信息比特数。当OUCI≤2,则UE选择第一个PUCCH资源集;当2<OUCI≤N2,则UE选择第二个PUCCH资源集;当N2<OUCI≤N3,则UE选择第三个PUCCH资源集;当N3<OUCI≤1706,则UE选择第四个PUCCH资源集。
其中,PUCCH资源集是基站为UE配置的,N2和N3的具体数值是基站为UE配置PUCCH资源集的时候设置的。第一个PUCCH资源集和第四PUCCH资源集的最大比特数是不需要设置的,并且,N2和N3均小于或等于1706。
可以理解的,PUCCH是物理上行控制信道,用于发送上行控制信息UCI,例如HARQ-ACK信息等。基站的PUCCH资源配置包括小区级(PUCCH-ConfigCommon)和UE级(PUCCH-Config)。小区级的PUCCH配置是基站的小区范围中的UE都可以使用的PUCCH配置参数,UE级的PUCCH配置是基站为UE专门配置的PUCCH参数。
示例性的,基站为UE配置的PUCCH-Config中最多可以包括4个PUCCH资源集。
如,第一个PUCCH资源集(PUCCH-ResourceSetId=0)。可以包含至多32个PUCCH资源,且调用第一个PUCCH资源集的条件为UCI的信息比特数(OUCI)小于等于2。
第二个PUCCH资源集(PUCCH-ResourceSetId=1),可以包含至多8个PUCCH资源,且调用第二个PUCCH资源集的条件为2<OUCI≤N2。其中,N2是由基站配置的,配置的值必须是4的倍数,并且N2小于等于1706,如果基站没有配置N2的数值,则N2=1706。如果N2=1706,基站为UE配置的PUCCH-Config中只包括2个资源集。
第三个PUCCH资源集(PUCCH-ResourceSetId=2),可以包含至多8个PUCCH资源,且调用第三个PUCCH资源集的条件为N2<OUCI≤N3。其中,N3是由基站配置的,配置的值必须是4的倍数,并且N3小于等于1706,如果基站没有配置N3的数值,则N3=1706。如果N3=1706,基站为UE配置的PUCCH-Config中只包括3个资源集。
第四个PUCCH资源集(PUCCH-ResourceSetId=3),可以包含至多8个PUCCH资源,且调用第四个PUCCH资源集的条件为N3<OUCI≤1706。其中,第四个PUCCH资源集对应的UCI的最大信息比特数为1706,不需要基站配置。
步骤602:UE根据DCI 1_0中的PUCCH资源索引确定出上述资源集中的资源。
在第一种情况中,基站向UE发送的PUCCH-Config,UE可以根据DCI 1_0中的PUCCH资源索引确定出资源集的一个PUCCH资源。
可以理解的,PUCCH-Config中的每个PUCCH资源都是基站为UE配置的。其中,PUCCH-Config可以配置每个资源的标识(Identifier,ID)、起始位置S和长度L等。UE可以根据DCI 1_0中的PUCCH资源索引确定出资源集中的PUCCH资源。例如,PUCCH资源索引可以是该PUCCH资源的ID。
示例性的,如图7所示,为确认时隙中PUCCH资源的示意图。以DCI 1_0中的K1为4,则UE可以根据DCI 1_0中的K1确定出向基站发送HARQ-ACK的时隙为slot n+K1为例。假设UE根据DCI 1_0确定出PUCCH资源的起始位S=2,L=2,则UE向基站发送HARQ-ACK占用的时隙的PUCCH资源如图7示意。
需要说明的是,Rel-15标准协议中,PUCCH资源的起始位S和长度L,都是按照slot来算的,并且基站为UE配置的PUCCH资源的边界不会超过slot的边界。PUCCH资源的边界可以通过S+L计算得到,由于slot最多有14个符号,则S+L≤14。如图8所示的PUCCH资源占用示意图,其中,图8中(a)表示ID=0的PUCCH资源,ID=0,S=2,L=2。图8中(b)表示ID=1的PUCCH资源,ID=1,S=10,L=3。
在第二种情况中,UE在基站的PUCCH-ConfigCommon中确定出PUCCH资源。UE可以根据DCI 1_0中的PUCCH资源索引确定PUCCH-ConfigCommon配置的PUCCH资源。
示例性的,PUCCH-ConfigCommon中仅配置一个资源集,该资源集中包括每个PUCCH资源的索引。通过PUCCH资源的索引可以确定出该PUCCH资源。如下表1所示,为PUCCH-ConfigCommon配置的示意。
表1:PUCCH-ConfigCommon中PUCCH资源的集合
其中,PUCCH-ConfigCommon配置的资源集合中包括16个PUCCH的资源,以及每个资源对应一个索引。并且,PUCCH-ConfigCommon配置的是初始BWP(Initial BWP)上的PUCCH资源,也就是说,上述PUCCH资源是在初始BWP上。
可以理解的,当UE确定DCI 1_0在对应时隙中PUCCH资源,则UE可以在slot的PUCCH资源上向基站发送HARQ-ACK。
其中,UE向基站发送多个HARQ-ACK比特组成的一个码本时,UE可以通过时隙上的一个PUCCH资源传输该码本,具体是在最新收到的DCI指示的PUCCH资源上传输该码本。例如,以一个slot上发送一个码本为例,两个HARQ-ACK比特组成一个码本,第一HARQ-ACK比特是第一个DCI调度的PDSCH的HARQ-ACK比特,第一个DCI指示PUCCH资源为S=2,L=2;第二HARQ-ACK比特是第二个DCI调度的PDSCH的HARQ-ACK比特,第二个DCI指示的PUCCH资源为S=6,L=2。则UE可以在S=6,L=2处的PUCCH资源上发送2比特的HARQ-ACK,也就是说,UE以slot为单位,在slot的一个PUCCH资源(S=6,L=2对应的PUCCH资源)上传输码本,该码本包含2比特的HARQ-ACK比特信息。
需要说明的,在UE使用的过程中,当UE执行不同的业务时,由于不同业务的对时延的要求不同,则UE向基站反馈该业务的时隙也不同。例如,UE执行超低时延高可靠通信(Ultra Reliable and Low Latency Communication,URLLC)业务时,URLLC对时延的要求高,则UE可以为该业务设置高优先级的码本。UE执行增强移动宽带(enhanced Mobile Broadband,eMBB)业务时,eMBB对时延的要求较低,UE为eMBB业务设置低优先级的码本,相比于URLLC业务的码本而言。也就是说,UE在执行上述两个任务时,每个任务都会产生一个码本,且两个码本的优先级不同。具体地说,基站为了保证上述两个业务都可以在满足时延要求的情况下进行,则基站可以针对每个业务的码本分别配置一个PUCCH-Config参数。
在Rel-16标准协议中,可以将一个时隙分为多个子时隙(sub-slot)。如图4中所示,可以将一个时隙分为两个7符号的子时隙,或者,将一个符号分为七个2符号的子时隙。可以理解的,基站向UE发送的PUCCH-Config中包括子时隙的长度,使得UE根据PUCCH-Config的子时隙的长度反馈HARQ-ACK。例如,PUCCH-Config中配置的子时隙的长度可以是7符号,2符号或3符号等。由此,基站可以为不用时延的业务配置PUCCH-Config,则两个业务的子时隙的长度可以不同。因此,UE可以根据PUCCH-Config中配置的信息产生两个码本,且两个码本中可以均为以slot为单位反馈的码本,也可以是以sub-slot为单位反馈的码本,或者一个是以slot为单位反馈的码本,一个是以sub-slot为单位反馈的码本。
其中,UE接收到来自基站的PUCCH-Config,则UE可以根据PUCCH-Config在子时隙的PUCCH资源上向基站传输HARQ-ACK。当UE需要向基站发送多个HARQ-ACK时,多个HARQ-ACK信息的比特可以组成一个HARQ-ACK码本(codebook)。
可以理解的,在Rel-16标准协议中,UE以子时隙为单位向基站发送HARQ-ACK码本。即一个sub-slot对应一个码本。在Rel-15标准协议中,UE以时隙为单位向基站发送HARQ-ACK码本。即一个slot对应一个码本。
示例性的,UE接收到来自基站的PUCCH-Config,UE根据PUCCH-Config中的子时隙的参数设置,则UE可以以一个sub-slot对应一个码本向基站发送HARQ-ACK。如果UE接收到来自基站的PUCCH-Config,UE接收到来自基站的DCI 1_0,UE按照DCI 1_0需要以slot对应一个码本向基站发送HARQ-ACK。由于PUCCH-Config设置的是以sub-slot对应一个码本向基站发送HARQ-ACK,则UE无法确定HARQ-ACK应该在时隙中的哪个sub-slot中传输HARQ-ACK。假设UE按照时隙为单位向基站反馈,则UE也无法根据DCI 1_0确定时隙上用于反馈HARQ-ACK的PUCCH资源。
本申请实施例提供一种资源指示方法,该方法可以应用于终端设备和网络设备通信传输的过程中。本申请实施例中以终端设备是UE(如,手机),网络设备是基站为例,对资源指示方法进行说明。如图9A所示,该方法可以包括步骤901a-步骤904a。
其中,基站可以用于向UE发送PDSCH,或者PDCCH,并且可以接收UE发送的上行数据信道,例如物理上行共享信道(physical uplink shared channel,PUSCH),以及PUCCH等。UE可以用于发送PUSCH以及PUCCH;UE还可以用于接收基站发送的PDSCH和PDCCH。
步骤901a:基站向UE发送DCI,DCI用于指示终端设备传输HARQ-ACK的时隙。
本申请实施例中,以DCI信息为DCI 1_0为例。也就是说,DCI 1_0指示K1,则传输HARQ-ACK的时隙为slot n+K1,其中,PDSCH在slot n结束,该PDSCH是DCI 1_0调度的。
步骤902a:UE接收到来自基站的DCI,并确定该DCI所指示的传输HARQ-ACK的时隙。
步骤903a:UE在DCI所指示的时隙的至少一个子时隙的PUCCH资源上发送HARQ-ACK。
可以理解的,基站发送的DCI 1_0中还可以包括PUCCH资源指示域,例如PUCCH resource indicator,该指示域可以指示一个PUCCH资源的索引,UE可以根据该PUCCH资源的索引确定出一个PUCCH资源,包括该PUCCH资源的起始位置和长度。
如果PUCCH资源未超过一个子时隙的边界,则UE可以在第一子时隙的PUCCH资源上向基站传输HARQ-ACK,其中,所述第一子时隙是指所述时隙的至少一个子时隙中的一个子时隙。如果PUCCH资源超过一个子时隙的边界,则UE可以在多个子时隙的PUCCH资源上向基站传输HARQ-ACK。UE确定时隙的方式可以如图5所示。
其中,PUCCH资源超过子时隙的边界是说,PUCCH的持续时间跨过了子时隙的边界,即PUCCH的起始符号和结束符号在两个不同的子时隙上。例如PUCCH的起始符号在第一子时隙(如图4中(a)中的sub-slot 0),PUCCH的结束符号在第二子时隙(如图4中(a)中的sub-slot 1)。示例性的,PUCCH资源的起始位置为4,长度为4,则PUCCH资源占用符号4、5、6、7,符号4属于sub-slot 0,符号7属于sub-slot 1。也就是说,PUCCH资源占用的符号数超过了sub-slot 0的边界。如果PUCCH的起始符号和结束符号都在同一个子时隙内(如图4中(a)中的sub-slot 0),则PUCCH资源未超过子时隙的边界。如图10所示,一个PUCCH资源索引指示的为第一PUCCH资源,第一PUCCH资源的ID=0,S=1,L=2。一个PUCCH资源索引指示的为第二PUCCH资源,第二PUCCH资源的ID=1,S=5,L=3。其中,ID=0的PUCCH资源未超过子时隙边界,ID=1的PUCCH资源超过子时隙边界。
可以理解的,由于DCI 1_0用于指示UE以时隙为单位向基站反馈HARQ-ACK,因此基站可以配置超过子时隙边界的PUCCH资源给DCI 1_0使用。或者,基站也可以为DCI 1_0配置不超过子时隙边界的PUCCH资源,具体基站是配置超过子时隙的边界还是不超过,属于基站自己的实现,本发明不做限定。
具体的,UE可以在一个子时隙的PUCCH资源上传输HARQ-ACK。或者,UE可以在多个子时隙的PUCCH资源上传输HARQ-ACK。
示例性的,当PUCCH资源占用一个子时隙中的部分或全部资源,则UE在时隙的第一子时隙的PUCCH资源上发送HARQ-ACK,第一子时隙是时隙的至少一个子时隙中的一个子时隙。或者,当PUCCH资源占用至少两个子时隙中每个子时隙的部分或全部资源,则UE在时隙的PUCCH资源上发送HARQ-ACK。
具体的,该PUCCH资源可以是DCI指示的PUCCH资源,也可以是基站配置的PUCCH资源。在时隙的PUCCH资源上发送HARQ-ACK,可以理解为以时隙的起始符号(i.e.符号0)为参考来确定PUCCH资源。例如,如果PUCCH资源的S=2,L=3,则PUCCH占据的符号为符号2,3,4。如果PUCCH资源的S=6,L=4,则PUCCH占据的符号为符号6,7,8,9。在子时隙的PUCCH资源上发送HARQ-ACK,可以理解为是以子时隙的起始符号为参考。例如,如果在子时隙0上,则参考符号为符号0。如果在子时隙1上,则参考符号为符号7,这里假设子时隙的长度为7。例如S=2,L=2,则PUCCH占据的符号为符号9,10。
具体地说,如果PUCCH资源占用一个子时隙中的部分或全部资源,则表示UE传输HARQ-ACK所占用的PUCCH资源是一个子时隙内的符号对应的资源。即PUCCH资源的长度未超过一个子时隙的边界。在这种情况下,UE可以在上述时隙的一个子时 隙(如第一子时隙)的PUCCH资源上发送HARQ-ACK。
如果PUCCH资源占用至少两个子时隙中每个子时隙的部分或全部资源,则表示UE传输HARQ-ACK所占用的PUCCH资源是至少两个子时隙内的符号对应的资源。即PUCCH资源的长度超过了一个子时隙的边界,如该PUCCH资源的长度跨越两个子时隙。在这种情况下,UE可以在上述时隙的PUCCH资源上发送HARQ-ACK。其中,上述时隙的PUCCH资源包括该时隙中多个子时隙内的符号对应的资源。
在第一种情况中,UE在时隙中的第一子时隙的PUCCH资源上传输HARQ-ACK。
也就是说,可以在一个子时隙中确定出DCI 1_0中的PUCCH资源索引所指示的PUCCH资源,则UE可以在一个子时隙上向基站传输HARQ-ACK。
在一种实施例中,由于一个时隙中包括至少两个子时隙,UE与基站可以预先定义第一子时隙。第一子时隙是可以是一个时隙的多个子时隙中的任一个子时隙。例如,UE接收到基站发送的PUCCH-Config参数,PUCCH-Config参数指示将一个时隙分为2个7符号的子时隙,如图4中(a)所示,则预定义的第一子时隙可以是sub-slot 0,或者,预定义的第一子时隙可以是sub-slot 1。或者,第一子时隙为所述至少两个子时隙中预定义的第N个子时隙,其中,所述N为正整数,N可以等于1或者2或者3或者4或者5或者6或者7。
在另一种实施例中,UE可以接收基站传输的指示信息,指示信息用于指示UE在时隙中的哪一个子时隙的PUCCH资源上传输HARQ-ACK。
其中,指示信息可以包含在DCI 1_0中,如以DCI 1_0中PUCCH资源指示域的冗余比特数作为该指示信息。例如,当PUCCH资源集中仅仅包含2个PUCCH资源时,PUCCH资源指示(PUCCH resource indicator,PRI)域中的1比特用来指示是哪一个PUCCH资源,用PRI的另外2比特来指示是哪一个子时隙,即确定出第一子时隙。例如,PRI的另外2比特=01,则确定在第一子时隙sub-slot 1上发送HARQ-ACK。或者,还可以通过控制信道单元(Control Channel Element,CCE)的索引,来确定第一子时隙。具体的,该CCE可以是PDCCH的第一个CCE,也可以是第n个CCE。
如图11A所示,一个PUCCH资源索引指示的为第一PUCCH资源,第一PUCCH资源的ID=0,S=1,L=2。一个PUCCH资源索引指示的为第二PUCCH资源,第二PUCCH资源的ID=1,S=5,L=2。也就是说,两个PUCCH资源索引所指示的PUCCH资源未超过子时隙的边界。
在第二种情况中,UE在时隙中的多个子时隙的PUCCH资源上传输HARQ-ACK。
可以理解的,DCI 1_0指示的传输HARQ-ACK所对应的PUCCH资源占用至少两个子时隙中每个子时隙的部分或全部资源,则UE在时隙中的多个子时隙的PUCCH资源上传输HARQ-ACK。因此,基站是以slot为边界配置的PUCCH资源。
示例性的,UE可以根据DCI 1_0中的PUCCH资源的索引确定出使用时隙上哪几个子时隙,并在确定出的多个子时隙的PUCCH资源上传输HARQ-ACK。如,子时隙的长度为2符号,一个时隙中包括7个子时隙。假设DCI 1_0中的PUCCH资源的索引对应的PUCCH资源的起始位置为3,L为4。UE可以根据该PUCCH资源的索引确定出在时隙的第3、4、5、6位传输HARQ-ACK。其中,时隙的第3、4、5、6位对应的子时隙包括:sub-slot 1、sub-slot 2和sub-slot 3。
也就是说,当在时隙中的多个子时隙的PUCCH资源上传输HARQ-ACK,则UE可以采用slot的方式确定出使用时隙上哪些子时隙。
示例性的,如图11B所示,一个PUCCH资源索引指示的为第一PUCCH资源,第一PUCCH资源的ID=0,S=1,L=2。一个PUCCH资源索引指示的为第二PUCCH资源,第二PUCCH资源的ID=1,S=5,L=3。也就是说,DCI 1_0中的PUCCH资源索引所指示的PUCCH资源超过子时隙的边界。
步骤904a:基站确定PUCCH资源,并在PUCCH资源上接收HARQ-ACK。
需要说明的,假设基站向UE发送的DCI是DCI 1_1,由于DCI 1_1是以子时隙为单位向基站传输HARQ-ACK,一般DCI 1_1中的PUCCH资源索引所指示的PUCCH资源的长度是小于或等于子时隙的长度。如果DCI 1_1中PUCCH资源索引所指示的PUCCH资源的长度是大于子时隙的长度,则UE可以去除PUCCH资源上超过子时隙长度所指示的子时隙的符号。
其中,当UE确定PUCCH资源超过了子时隙的边界,则UE可以重新确定PUCCH资源的起始位置和长度。示例性的,PUCCH资源的索引对应的起始位置为S1,长度为L1。UE可以根据预设规则确定出更新后的PUCCH资源的起始位置为S2,长度为L2。其预设规则可以为:假设子时隙的长度为N,S2=f1(S1,N),其中,f1(S1,N)表示S1mod N,即S1除以N并取余数。L2=f2(L1,N),其中,f2(L1,N)表示L1mod N,即S1除以N并取余数。可以理解的,此处f1和f2为一个函数,可以表示S1和N的运算关系,此处f1(S1,N)表示S1mod N为示例。
在一种可能的实施方式中,UE还可以根据DCI 1_0中的PRI和基站发送的CCE共同确定出第一子时隙。例如,可以将子时隙分组,CCE指示是哪一组,PRI指示是该分组中的哪一个子时隙。其它方式也可以。
需要说明的是,对于时延性要求较高的业务,如URLLC业务,可以在使用一个子时隙的PUCCH资源向基站发送URLLC业务的码本。例如,UE接收到的URLLC任务的DCI信息,DCI信息中包括1个PUCCH资源索引,且第一PUCCH资源索引对应第一PUCCH资源的S=1,L=2;UE之后又收到一个DCI,指示第二PUCCH资源索引,第二PUCCH资源索引对应第二PUCCH资源的S=4,L=2;UE可以使用第一子时隙中的第二PUCCH资源的S=4,L=2传输该码本。
在一些实施方式中,基站可以先向UE发送PUCCH配置参数,PUCCH配置参数可以指示子时隙的长度。这样,UE可以根据PUCCH配置参数所指示的子时隙的长度,并以子时隙为单位传输HARQ-ACK。如图9B所示,为本申请实施例提供的资源指示方法的流程图,该方法可以包括步骤901b-步骤906b。
需要说明的,图9B中的步骤903b-步骤906b与上述实施例中的步骤901a-步骤904a相同,此处不予赘述。
步骤901b:基站向UE发送第一PUCCH配置参数,第一PUCCH配置参数包括子时隙的长度。
其中,第一PUCCH配置参数为:PUCCH-Config。PUCCH-Config包括基站配置的子时隙的长度。
可以理解的,PUCCH-Config中还可以包括PUCCH资源的起始位置和长度,使得 基站可以根据PUCCH-Config参数中的PUCCH资源反馈HARQ-ACK。
步骤902b:UE接收来自基站的第一PUCCH配置参数,确定第一配置参数中子时隙的长度。
其中,UE接收到PUCCH-Config之后,UE可以根据PUCCH-Config中指示的子时隙的长度反馈HARQ-ACK,并且根据PUCCH-Config参数中的PUCCH资源反馈HARQ-ACK。
需要说明的,PUCCH-Config对应于一个BWP,由于PUCCH-ConfigCommon参数对应于初始BWP。基站在设置PUCCH-Config参数时,还可以设置对应于PUCCH-Config的BWP。示例性的,一个UE可以包括4个BWP,基站可以为每个BWP设置对应的PUCCH配置参数。基站和UE通信的过程中,UE仅使用一个BWP,并调用基站为该BWP配置的PUCCH资源。
本申请实施例提供的方法中,上述UE接收到用于指示传输HARQ-ACK的时隙的DCI,则可以在该DCI所指示的时隙的PUCCH资源上向网络设备发送HARQ-ACK。具体的,UE可以在该时隙的至少一个子时隙的PUCCH资源上向网络设备发送HARQ-ACK。也就是说,UE可以在该时隙的一个子时隙的PUCCH资源上发送HARQ-ACK,也可以在该时隙的多个子时隙的PUCCH资源上发送HARQ-ACK。这样,可以提高了UE向网络设备发送HARQ-ACK的灵活性。
本申请实施例还提供一种资源指示方法,如图12所示,该方法可以包括步骤1201-步骤1206。
步骤1201:基站向UE发送第一PUCCH配置参数,第一PUCCH配置参数用于配置初始BWP中的PUCCH资源。
其中,此处的第一PUCCH配置参数与上述实施例中的第一PUCCH配置参数不同,此处的第一PUCCH配置参数是小区级的PUCCH配置参数。PUCCH-ConfigCommon参数配置的PUCCH资源是通过初始BWP调用的,并且,PUCCH-ConfigCommon指示以时隙为单位向基站传输HARQ-ACK。
步骤1202:UE接收到来自基站的第一PUCCH配置参数,第一PUCCH配置参数用于配置初始BWP中的PUCCH资源。
可以理解的,当UE接收到来自基站的第一PUCCH配置参数,则需要在PUCCH-ConfigCommon对应的初始BWP确定PUCCH资源并传输HARQ-ACK。
步骤1203:基站向UE发送DCI,该DCI可以用于指示传输HARQ-ACK的时隙。
本申请实施例中,以DCI信息为DCI 1_0为例。UE确定按照时隙为单位向基站发送HARQ-ACK。
步骤1204:UE接收到来自基站的DCI,该DCI可以用于指示传输HARQ-ACK的时隙。
其中,UE还可以根据DCI 1_0中的PUCCH资源索引确定出传输HARQ-ACK的资源。这样,UE可以在DCI 1_0的指示下,在DCI 1_0指示的时隙上对应的PUCCH资源传输HARQ-ACK。
步骤1205:UE通过激活BWP,在时隙的PUCCH资源上发送HARQ-ACK。
可以理解的,激活BWP是UE当前正在使用的BWP。也就是说,UE当前使用激 活BWP向基站传输HARQ-ACK。如果基站按照PUCCH-ConfigCommon所指示的初始BWP传输HARQ-ACK,则需要切换BWP。由于切换BWP会影响UE和基站通信的稳定性,则UE可以在激活BWP上向基站传输HARQ-ACK。
由于基站可以为每个BWP配置PUCCH资源,则UE可以通过激活BWP传输HARQ-ACK。
步骤1206:基站确定PUCCH资源,并在PUCCH资源上接收HARQ-ACK。
其中,步骤1206与上述实施例中的步骤906b相同,此处不与赘述。
本申请实施例还提供一种资源指示方法,如图13所示,该方法可以包括步骤1301-步骤1308。
步骤1301:基站向UE发送第一PUCCH配置参数,第一PUCCH配置参数用于配置初始BWP中的PUCCH资源。
其中,第一PUCCH配置参数是PUCCH-ConfigCommon参数。PUCCH-ConfigCommon参数配置的PUCCH资源是通过初始BWP调用的。
步骤1302:UE接收到来自基站的第一PUCCH配置参数,第一PUCCH配置参数用于配置初始BWP中的PUCCH资源。
其中,步骤1301和步骤1302与上述步骤1201和步骤1202相同,此处不予赘述。
步骤1303:基站向UE发送第二PUCCH配置参数,第二PUCCH配置参数包括子时隙的长度。
其中,第二PUCCH配置参数时UE级的PUCCH配置参数。
步骤1304:UE接收来自基站的第二PUCCH配置参数,确定第二配置参数中子时隙的长度。
步骤1305:基站向UE发送DCI,DCI用于指示UE传输HARQ-ACK的时隙。
步骤1306:UE接收到来自基站的DCI,并确定该DCI所指示的传输HARQ-ACK的时隙。
其中,步骤1303-步骤1306与上述实施例中的步骤901-904相同,此处不予赘述。
步骤1307:UE通过激活BWP,在DCI所指示的时隙的至少一个子时隙的PUCCH资源上发送HARQ-ACK。
步骤1308:基站确定PUCCH资源,并在PUCCH资源上接收HARQ-ACK。
其中,步骤1307和步骤1308与上述步骤1205和步骤1206相同,此处不予赘述。
需要说明的,基站预先给UE配置的是小区级的PUCCH配置参数,基站再次给UE配置的是UE级的PUCCH配置参数。当UE接收到来自基站的DCI 1_0,由于DCI 1_0是以时隙为单位向基站反馈HARQ-ACK,DCI 1_0可以通过激活BWP在DCI 1_0指示的时隙的PUCCH资源上发送HARQ-ACK。
