Description

多载波调度的方法和装置
本申请要求于2021年08月31日提交中国专利局、申请号为202111010280.0、申请名称为“多载波调度的方法和装置”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
本申请涉及通信领域,更具体地,涉及多载波调度的方法和装置。
背景技术
数据传输过程中,下行控制信息(downlink control information,DCI)承载于物理下行控制信道(physical downlink control channel,PDCCH)中,DCI通过调度数据信道来调度载波。现有技术中,每调度一个载波都需要发送一个DCI,若需要调度多个载波,则需要发送多个DCI,一个DCI用于调度一个载波,一个DCI通过一个PDCCH传输,这样,导致PDCCH的开销大,较多的DCI也会增加盲检的复杂度。
发明内容
本申请实施例提供一种多载波调度的方法,可以减少PDCCH的资源开销和盲检复杂度,以提高系统传输性能。
第一方面,提供了一种多载波调度的方法,包括:
终端设备接收第一配置信息,所述第一配置信息用于配置第一下行控制信息DCI和第二DCI,所述第一DCI用于调度M个载波,所述第二DCI用于调度一个载波,M为大于1的整数,所述第一DCI的第一监听比特长度与所述第二DCI的第一监听比特长度不同;
所述终端设备根据第二监听比特长度,监听所述第一DCI和所述第二DCI,其中,所述第二监听比特长度是根据所述第一DCI的第一监听比特长度和所述第二DCI的第一监听比特长度确定的。
本申请实施例提供的多载波调度的方法,网络设备通过第一配置信息配置用于调度多载波的第一DCI和用于调度单载波的第二DCI,终端设备可以基于两个DCI的不同的第一监听比特长度得到一个用于盲检的第二监听比特长度,减少了终端设备对DCI进行盲检的盲检复杂度,提高了系统传输性能;以及,通过第一DCI调度多个载波减少了PDCCH的资源开销。

为便于理解,下面先对本申请实施例涉及的相关术语进行介绍。
1、PDCCH
物理下行控制信道(physical downlink control channel,PDCCH)承载网络设备发送给终端设备的下行控制信息(downlink control information,DCI)。DCI包括以下内容:承载上行数据传输相关的控制信息,如数据传输的资源分配信息、时隙内上/下行资源的格式信息,以及上行数据信道和信号的功率控制信息等;动态时隙配置的信息;资源抢占信息等。终端设备在接收DCI后,根据DCI进行数据的发送和接收,或是执行相应的操作。
2、控制信道单元
控制信道单元(control channel element,CCE)是构成PDCCH的基本单位,占用频域上6个资源块(resource block,RB)。一个给定的PDCCH可由1个、2个、4个、8个和16个CCE构成,其具体取值由DCI长度(DCI size)和所需的编码速率决定。构成PDCCH的CCE数量被称为聚合等级(aggregation level,AL)。网络设备可根据实际传输的无线信道状态对PDCCH的聚合等级进行调整,实现链路自适应传输。例如,网络设备与终端设备在无线信道状态比较恶劣时,相比于无线信道状态良好时,构成PDCCH的CCE的数量会更多,即PDCCH聚合等级会更大。
3、搜索空间(search space)
搜索空间是聚合等级下候选PDCCH(PDCCH candidate)的集合,其中,待盲检的PDCCH称为候选的PDCCH。因为网络设备实际发送的PDCCH的聚合等级随时间可变,而且由于没有相关信令告知终端设备,所以,终端设备需在不同聚合等级下盲检PDCCH。
为了降低终端设备盲检的复杂度,需要限制盲检的CCE的集合。候选PDCCH的起始CCE序号需要能够被此候选PDCCH的CCE数整除。例如,聚合等级2的候选PDCCH只能从可被2整除的CCE序号开始,同样的原则适用于其他聚合等级的搜索空间。此外,搜索空间所在的CCE集合,可进一步根据搜索空间集合配置信息中的高层参数和预定义的规则确定。
协议将搜索空间划分为公共搜索空间(common search space,CSS)和UE特定搜索空间(UE specific search space,USS),对于不同的信息在不同的搜索空间里进行盲检。
4、盲检
用于调度不同数据传输的DCI可以用不同的无线网络临时标识(radio network  temporary identifier,RNTI)进行加扰,例如,RNTI可以包括小区标识(cell-RNTI,C-RNTI)、接入标识(random access-RNTI,RA-RNTI)、寻呼标识(paging-RNTI,P-RNTI)等,其中,C-RNTI可以用于对调度用户数据的DCI加扰,RA-RNTI可以用于对调度网络设备发送给终端设备的随机接入响应消息加扰,P-RNTI可以用于对寻呼消息进行加扰。
以C-RNTI为例,不同用户的PDCCH可以通过其对应的C-RNTI进行区分,即将DCI的循环冗余校验(cyclic redundancy check,CRC)由C-RNTI加掩。用户一般不知道当前发送的DCI的具体格式,也不知道自己所需要的DCI在哪个候选PDCCH上,但是,用户知道自己当前在期待什么信息,对于所期待的不同信息,用户采用相应的RNTI和网络设备配置的候选PDCCH上的配置信息做CRC校验,如果CRC校验成功,那么用户就知道这个DCI是自己需要的,也知道相应的DCI格式,从而进一步解析出该DCI的内容。
盲检过程中,终端设备在搜索空间中对所有候选PDCCH进行盲检,对于不同的信息,终端设备在不同的搜索空间中进行盲检。例如paging,SI,RACH response等信息是需要所有终端设备都要去监听的,对于这类信息,终端设备在CSS中进行盲检。例如上行或下行调度指令等信息跟特定终端设备相关,仅需要特定的终端设备监听,对于这类信息,终端设备在USS中进行盲检。此外,盲检过程中,终端设备可以基于配置信息确定DCI长度,根据DCI长度进行盲检,这样,可以减少盲检复杂度。
5、DCI格式(DCI format)
对于数据传输,NR目前主要支持3种系列的DCI格式,分别是:DCI format x_0、DCI format x_1、DCI format x_2,不同系列的DCI格式的x的取值不同。示例性地,在DCI format x_0系列中,x的取值可以为0或1,对应地,包括的DCI格式为:DCI format 0_0、DCI format 1_0;在DCI format x_1系列中,x的取值可以为0或1,对应地,包括的DCI格式为:DCI format 0_1、DCI format 1_1;在DCI format x_2系列中,x的取值可以为0或1,对应地,包括的DCI格式为:DCI format 0_2、DCI format 1_2。应理解,上述举例的3种系列的DCI格式仅为示意性说明,各个系列的DCI格式可以有更多的DCI格式。例如,在DCI format x_2系列中,还可以包括DCI format 2_2、DCI format 3_2、DCI format 4_2等格式的DCI。
综上举例,NR目前主要支持的DCI格式为以下6种格式:DCI format 0_0、DCI format 1_0、DCI format 0_1、DCI format 1_1、DCI format 0_2、DCI format 1_2。DCI format 0_0用于小区内物理上行共享信道(physical uplink shared channel,PUSCH)的调度。DCI format 0_1用于服务小区内一个或多个PUSCH的调度,或用于向UE指示配置授权下行反馈信息(configured grandownlink feedback information,CG-DFI)。DCI format 0_2用于服务小区内PUSCH的调度。DCI format 1_0用于下行小区内物理下行共享信道(physical downlink shared channel,PDSCH)的调度。DCI format 1_1用于小区内PDSCH的调度。DCI format 1_2用于小区内PDSCH的调度。不同格式的DCI包含的域的内容都不同。
按照上行和下行,上述6种格式的DCI可以分为两类:用于调度物理上行共享信道(physical uplink shared channel,PUSCH)的DCI和用于调度物理下行共享信道(physical downlink shared channel,PDSCH)的DCI,其中,DCI format 0_0、DCI format 0_1、DCI format 0_2为用于调度PUSCH的DCI,DCI format 1_0、DCI format 1_1、DCI format 1_2为用于调度PDSCH的DCI。
按照功能,上述6种格式的DCI也可以分为两类:回退DCI(fallback DCI)和非回退DCI(non-fallback DCI),其中,DCI format 0_0和DCI format 1_0为回退DCI,DCI format 0_1、DCI format 1_1、DCI format 0_2、DCI format 1_2为非回退DCI。
在一些实施例中,上述6种DCI格式中包含的至少部分域可以分别如下表1至表6所示。
表1 DCI format 0_0
Figure PCTCN2022090460-appb-000001
在上述DCI format 0_0中,除了频域资源分配(frequency domain resource assignment,FDRA)域之外,其余的域的长度都是固定的,不需要通过无线资源控制(radio resource control,RRC)信令配置,因此,DCI format 0_0的信息比特大小仅与FDRA域有关,DCI format 0_0的FDRA域仅与
Figure PCTCN2022090460-appb-000002
的取值有关。
表2 DCI format 1_0
Figure PCTCN2022090460-appb-000003
Figure PCTCN2022090460-appb-000004
上述DCI format 1_0为采用C-RNTI加扰且FDRA域不是全为1的情况下的DCI格式,或采用CS-RNTI加扰的DCI格式。在该DCI format 1_0中,除了FDRA域之外,其余的域的长度都是固定的,不需要通过RRC信令配置,因此,DCI format 0_1的信息比特大小仅与FDRA域有关,DCI format 1_0的FDRA域仅与
Figure PCTCN2022090460-appb-000005
的取值有关。
综上所述,在回退DCI中,除了FDRA域以外,其他各个字段的比特长度和内容都不受RRC配置的影响,是确定的。因此,影响回退DCI比特长度的只有FDRA域的长度,具体地,影响DCI format 0_0的长度的参数为
Figure PCTCN2022090460-appb-000006
影响DCI format 1_0的长度的参数为
Figure PCTCN2022090460-appb-000007
Figure PCTCN2022090460-appb-000008
可以采用初始上行BWP(initial UL BWP),也可以采用激活上行BWP(active UL BWP),同样的,
Figure PCTCN2022090460-appb-000009
可以采用初始下行BWP,也可以采用激活下行BWP,这取决于该DCI对应的场景,例如,公共搜索空间(common search space,CSS)或用户特定的搜索空间(UE-specific search space,USS),这将导致DCI format 0_0和DCI format 1_0分别具有两个长度,具体地,DCI format 0_0在CSS中具有一个长度,DCI format 0_0在USS中具有一个长度,总共是两个长度,DCI format 1_0在CSS中具有一个长度,DCI format 1_0在USS中具有一个长度,总共是两个长度。
表3 DCI format 0_1

表4 DCI format 1_1
Figure PCTCN2022090460-appb-000012
Figure PCTCN2022090460-appb-000013
在上述DCI format 0_1和DCI format 1_1中,除了FDRA域之外,还有很多域的长度都不是固定的,需要通过RRC信令配置,例如,载波指示位、带宽部分指示、时域资源 分配位等等。因此,DCI format 0_1和DCI format 1_1的信息比特大小不仅仅与
Figure PCTCN2022090460-appb-000014
的取值有关,是灵活可变的。
表5 DCI format 0_2
Figure PCTCN2022090460-appb-000015
Figure PCTCN2022090460-appb-000016
表6 DCI format 1_2
Figure PCTCN2022090460-appb-000017
Figure PCTCN2022090460-appb-000018
在上述DCI format 0_2和DCI format 1_2中,除了FDRA域之外,还有很多域的长度都不是固定的,需要通过RRC信令配置。因此,DCI format 0_2和DCI format1_2的信息比特大小不仅仅与
Figure PCTCN2022090460-appb-000019
的取值有关,是灵活可变的。
应理解,上述6种DCI格式可以包括如表1至表6中更多或更少的域,不应对本申请实施例构成限定。
可以看出,不同DCI格式本质上对应不同长度的信息比特,DCI格式越多会导致盲检的复杂度越大。因为终端设备需对搜索空间中候选PDCCH上可能传输的所有DCI格式进行译码,进而译码复杂度随之增大。为了尽可能减少UE盲检测的复杂度,在NR中,规定了DCI长度预算(DCI size budget),需满足下列两个判断条件,即:
(1)1个小区内1个时间单元(例如,时隙或PDCCH监听时机)内不同的DCI长度(DCI size)的数量不超过4个;
(2)1个小区内1个时间单元(例如,时隙或PDCCH监听时机)内监听的经过C-RNTI加扰的不同的DCI长度的数量不超过3个。
这里的不同的DCI长度,应理解为天然配置的DCI长度与其他DCI长度不同,或者通过对天然配置的DCI长度进行对齐操作后确定的DCI长度仍与其他的DCI长度不同,其中,对齐操作包括补零操作或截短操作,下文关于对齐操作的解释同此处。补零操作表示对DCI增加至少一个比特零以增加DCI长度的操作。截短操作表示将一个DCI截短减少DCI长度的操作,具体地,截短操作可以是删除相应字段的部分信息比特的操作,也可以是删除相应字段的全部信息比特操作。
本文中的“天然配置”,应理解为网络设备通过配置信息配置的DCI中各个域所占比特长度的大小。终端设备根据上述配置信息的配置,可以确定DCI的信息比特长度(上文各个表的DCI格式的DCI的信息比特大小,也是下文的原始比特长度),即,DCI的信息比特长度可以仅根据配置信息得到,不包含经过其他操作(例如,对DCI的信息比特长度进行补零操作或截短操作等)后得到的处理后的比特长度,或者说,DCI的信息比特长 度是在对DCI进行补零或截短操作之前的比特长度。示例性地,上述配置信息可以为RRC信令,媒体接入控制(medium access control,MAC)控制单元(control element,CE)信令或DCI。
在上述DCI长度预算的DCI长度中,无论是天然配置的DCI长度,还是通过对天然配置的DCI长度进行对齐操作后确定的DCI长度,都可以理解为盲检过程中使用的DCI长度。
例如,一个DCI的DCI格式是DCI format 0_0,基于配置信息得到的DCI的各个域实际占用的比特长度为20个比特(不包括CRC),即,DCI的信息比特长度为20个比特。若基于DCI长度预算,不需要对DCI长度进行对齐操作,那么,盲检过程中使用的一个DCI长度则为20。若基于DCI长度预算,需要对DCI长度进行补零操作,将DCI长度增加至25,那么,盲检过程中使用的一个DCI长度则为25。若基于DCI长度预算,需要对DCI长度进行截短操作,将DCI长度缩短至18,那么,盲检过程中使用的一个DCI长度则为18。
综上,由于存在多种不同长度的DCI,为了满足对DCI长度预算的限制,在网络设备和终端设备传输DCI的过程中,可能需要对不同长度的DCI进行对齐操作(补零操作或截短操作),减少DCI长度的个数,从而降低终端设备对DCI的盲检复杂度。
需要说明的是,在确定DCI长度是否满足DCI长度预算时,以被调度的载波单元对应的小区的DCI长度预算进行确定。例如,4个DCI都调度载波单元1,载波单元1对应小区1,在判断基于该4个DCI得到的DCI长度是否满足DCI长度预算时,以小区1的DCI长度预算作为参考。
6、载波
载波是一个特定频率的无线电波,可用于传输数据。在载波聚合中,两个以上的载波单元(component carrier,CC)聚合在一起,用于传输数据。为了便于描述,下文的“载波”可以理解为“载波单元”。
例如,终端设备可使用3个载波,3个载波中的一个载波称为主载波(primary component carrier,PCC),其余两个载波称为辅载波(secondary component carrier)。在一些实施例中,一个载波对应一个小区,在上述3个载波中,主载波对应主小区(primary cell,Pcell),一个辅载波对应一个辅小区(secondary cell,Scell)。在另一些实施例中,多个载波也可以对应一个小区,例如,一个小区中包含至少两个下行载波,至少一个上行载波。本申请实施例中的载波可以是一个载波对应一个小区中的载波,也可以是多个载波对应一个小区中的载波。
7、载波聚合
为了高效地利用零碎的频谱以提高传输速率,载波聚合(carrier aggregation,CA)支持不同载波之间的聚合,载波聚合将2个或更多的载波聚合在一起以支持更大的传输带宽。根据参与聚合的载波是否属于同一频段以及是否在频域上连续,载波聚合可分为:频段内连续载波聚合、频段内非连续载波聚合和频段间载波聚合,其中,频段内连续载波聚合中的载波属于同一个频段且在频域上连续,频段内非连续载波聚合中的载波属于同一个频段但在频域上不连续,频段间载波聚合属于不同频段。
基于载波聚合,网络设备在调度终端设备的时候,可以通过多个DCI调度多个载波进 行数据传输,一个DCI用于调度一个载波,被调度的载波上传输用于承载数据的数据信道。在载波聚合的自调度中,网络设备在多个载波的每个载波上发送一个DCI,每个载波上的DCI用于调度该载波。在载波聚合的跨载波调度中,网络设备可在一个载波上发送多个DCI,该多个DCI调度的多个载波可以包括用于发送该多个DCI的载波,也可以不包括用于发送该多个DCI的载波,也就是说,在跨载波调度中,允许在一个载波上发送的DCI调度另一个载波,即,DCI在一个载波上传输,对应的数据在另一个载波上传输。
需要说明的是,由于DCI承载于PDCCH中,所以,本申请实施例所说的“在载波上发送DCI”也可以描述为在“在载波上发送PDCCH”,同理,由于数据承载于数据信道(PDSCH或PUSCH)中,所以,本申请实施例所说的“在载波上传输数据”也可以描述为“在载波上传输数据信道”,以及,“调度载波”也可以描述为“调度载波上的数据信道(PDSCH或PUSCH)”。
以DCI调度用于传输PDSCH的载波为例,图2是本申请实施例提供的载波聚合的示意性场景图。图2中的(a)示出的是载波聚合中自调度的场景,每个小区对应一个载波,主小区(Pcell)对应的载波1(主载波)上发送的DCI1(或PDCCH1)用于调度用于传输PDSCH1的载波1,辅小区1(Scell)对应的载波2(辅载波)上发送的DCI2(或PDCCH2)用于调度用于传输PDSCH2的载波2,辅小区2(Scell2)对应的载波3上发送的DCI3(或PDCCH3)用于调度用于传输PDSCH3的载波3。图2中的(b)示出的是载波聚合中跨载波调度的场景,主小区(Pcell)对应的载波1载波发送了两个DCI,分别是DCI1和DCI2,DCI1用于调度用于传输PDSCH1的载波1,DCI2用于调度用于传输PDSCH2的载波2,其中,在载波1上发送的DCI2用于调度用于传输PDSCH2的载波2的场景则为跨载波调度的场景。图2中的(c)示出的是载波聚合中跨载波调度的另一场景,主小区(Pcell)对应的载波1载波发送了两个DCI,分别是DCI1和DCI2,DCI1用于调度用于传输PDSCH1的载波2,DCI2用于调度用于传输PDSCH2的载波3,DCI1和DCI2分别调度的两个载波都是跨载波调度的场景。应理解,图2仅是示意性示出DCI调度用于传输PDSCH的载波的情况,DCI调度用于传输PUSCH的载波的情况与图2类似,不再赘述。
在上述基于载波聚合进行载波调度的场景中,每调度一个载波都需要发送一个DCI,若需要调度多个载波,需要发送多个DCI,一个DCI用于调度一个载波,一个DCI通过一个PDCCH传输,这样,导致PDCCH的开销大,较多的DCI也会增加盲检的复杂度。此外,由于控制资源是有限的,一个终端设备可用的PDCCH开销大的话,会导致可调度的终端设备的数量减少。
为了解决上述问题,一个DCI可用于调度多个(例如,两个)载波,以减少PDCCH的开销,以及减少盲检复杂度。
在通过一个DCI调度多个载波的方案中,DCI可通过两种调度方式调度多个载波。
第一种调度方式
DCI通过调度多个数据信道来调度多个载波。即,一个DCI调度多个数据信道,每个数据信道对应至少一个载波,每个数据信道对应至少一个物理传输块。具体地,每个数据信道可以在该至少一个载波上传输,每个数据信道用于承载该至少一个物理传输块,每个物理传输块映射在该至少一个载波的传输资源上。在该调度方式中,每个数据信道对应至少一个载波,有以下三种情况。在第一种情况中,每个数据信道都对应一个载波。在第二 种情况中,多个数据信道中部分数据信道的每个数据信道对应一个载波,另一部分数据信道的每个数据信道对应多个载波,例如,DCI调度2个数据信道,一个数据信道对应一个载波,另一个数据信道对应多个载波。在第三种情况中,每个数据信道都对应多个载波。
第二种调度方式
DCI通过调度一个数据信道来调度多个载波。即,一个DCI调度一个数据信道,该数据信道对应多个载波,该数据信道对应至少一个物理传输块。具体地,该数据信道在多个载波上传输,该数据信道用于承载至少一个物理传输块,每个物理传输块映射在该多个载波的传输资源上。
以一个DCI调度两个载波以及载波用于传输PDSCH为例,图3和图4是本申请实施例提供的多载波调度的示意性场景图。图3对应第一种调度方式,在图3中,一个承载于PDCCH的DCI调度两个PDSCH,一个PDSCH对应一个载波,PDSCH1对应载波1,PDSCH2对应载波2。图4对应第二种调度方式,在图4中,一个承载于PDCCH的DCI调度一个PDSCH,该PDSCH对应2个载波,即,该PDSCH在2个载波上传输,该2个载波为载波1和载波2。
在上述一个DCI调度多个载波的方案中,关于如何实现通过一个DCI调度多个载波的具体内容,现有技术中并没有更多涉及,因此,本申请实施例的目的在于,通过相关设计实现通过一个DCI调度多个载波的功能。
在本申请实施例中,为了便于区分,将用于调度一个载波的DCI统称为单载波调度DCI,采用sDCI表示,将用于调度多个载波的DCI统称为多载波调度DCI,采用mDCI表示。应理解,sDCI和mDCI仅是为了区分两种不同功能的DCI所起的名称,还可以采用其他名称对其进行定义,本申请实施例不做任何限定。
在一些实施例中,sDCI可以包括现有或未来定义的任意一种或多种DCI格式,sDCI用于调度一个载波。例如,sDCI可以包括如下至少一种格式:DCI format 0_0、DCI format 1_0、DCI format 0_1、DCI format 1_1、DCI format 0_2以及DCI format 1_2。
在一些实施例中,mDCI可以包括本申请实施例定义的一种或多种DCI格式。为了便于区分,将mDCI的DCI格式记为DCI format x_3,x的取值为整数。示例性地,被调度的载波用于传输PUSCH对应的mDCI的DCI格式可以是DCI format 0_3,x的取值为0,被调度的载波用于传输PDSCH对应的mDCI的DCI的格式可以是DCI format 1_3,x的取值为1。
基于上述定义的sDCI和mDCI,终端设备和网络设备传输DCI的过程中,包括sDCI和mDCI共存与不共存两种场景。
在mDCI和sDCI共存的场景中,网络设备支持终端设备可以在一个时间单元内盲检sDCI和mDCI,在该时间单元内,网络设备可以发送sDCI或mDCI以调度载波。例如,网络设备可以通过高层信令为终端设备配置用于盲检的DCI格式,包括sDCI和mDCI的DCI格式,终端设备基于网络设备的配置在该时间单元内盲检sDCI和mDCI,以得到网络设备实际发送的DCI。
在mDCI和sDCI不共存的场景中,网络设备不支持终端设备在一个时间单元内盲检sDCI和mDCI,在该时间单元内,终端设备盲检sDCI,网络设备发送sDCI以调度载波,或者,终端设备盲检mDCI,网络设备发送mDCI以调度载波。
基于上述定义的sDCI和mDCI以及sDCI和mDCI是否共存的场景,本申请实施例主要涉及以下三方面的内容。
第一方面,mDCI的DCI格式的设计。
第二方面,在mDCI和sDCI共存的场景下,确定不同DCI的DCI长度,以减少DCI长度的个数,以降低终端设备对DCI的盲检复杂度。
第三方面,在mDCI和sDCI不共存的场景下,mDCI对应的调度模式和sDCI对应的调度模式之间的切换。
由于本申请实施例会较多涉及DCI长度,在描述上述三方面内容之前,为了便于描述,本申请实施例定义了DCI的原始比特长度。
DCI的原始比特长度即为上文的DCI的信息比特长度,表示的是网络设备通过配置信息配置的DCI中各个域所占比特长度的大小,终端设备根据上述配置信息的配置,可以确定DCI的原始比特长度,即,DCI的原始比特长度可以仅根据配置信息得到,不包含经过其他操作(例如,对齐操作)后得到的处理后的比特长度,或者说,DCI的原始比特长度是在对DCI进行对齐操作之前的比特长度。以上文各个表的DCI格式为例,DCI的信息比特大小为DCI的原始比特长度,例如,表1中DCI format 0_0的DCI的信息比特长度即为DCI format 0_0的原始比特长度。
下面,分别对上述三方面内容做详细说明。
第一方面,mDCI的DCI格式的设计
若mDCI通过调度多个数据信道来调度多个载波,每个数据信道对应至少一个载波,每个数据信道用于承载至少一个(例如,1个或2个)物理传输块,mDCI中包含的域与现有的通过调度一个数据信道来调度一个载波的sDCI存在较大差异,所以,重点在于设计这种调度方式下的mDCI。对于通过调度一个数据信道来调度多个载波的mDCI的情况,mDCI的格式与现有的格式可相同,区别在于,现有的DCI调度的数据信道调度一个载波,本申请实施例的mDCI调度的数据信道调度多个载波。
以下,为了便于描述mDCI的DCI格式,以M个数据信道和对应的M载波为例进行描述,其中,该M个数据信道和该M个载波一一对应。
mDCI的第一种DCI格式
这种通过调度M个数据信道来调度M个载波的调度方式的mDCI,包括两类域,第一类域包括至少一个共享域,第二类域包括至少一个独立域。每个共享域中承载的信息与在M个载波上传输的M个数据信道相关,具体地,每个共享域承载的信息是该M个数据信道共用的信息,换句话说,每个共享域承载的信息是mDCI的一部分调度信息,用于调度该M个数据信道。每个独立域包括M个子域,该M个子域与M个载波一一对应,每个子域承载的信息与对应的载波上传输的数据信道相关,换句话说,每个子域承载的信息是mDCI的一部分调度信息,用于调度对应的数据信道。
以下,以定义的mDCI的DCI format 1_3以及mDCI调度两个载波为例,描述mDCI的DCI格式。
如表7所示的DCI format 1_3,DCI format 1_3通过调度两个数据信道来调度两个载波,一个数据信道对应一个载波,将两个数据信道记为数据信道1和数据信道2,DCI format 1_3中的所有域分为共享域和独立域两种属性的域。
对于独立域,各个独立域的功能不同,每个独立域包括两个子域,左边的第一个子域对应数据信道1,右边的第二个子域对应数据信道2,比特数是一个子域占用的比特的数量,表示一个子域的比特长度。以表7中的第一行的调制和编码策略(modulation and coding scheme,MCS)域为例,MCS域是独立域,包括两个子域,分别为左边的针对传输块11的MCS1域(两个子域中的一个子域)和右边的针对传输块12的MCS2域(两个子域中的另一个子域),针对传输块11的MCS1域对应数据信道1,用于承载在数据信道1上传输的数据的MCS信息,右边的针对传输块12的MCS2域对应数据信道2,用于承载在数据信道2上传输的数据的MCS信息。一个子域占用5个比特,即,一个子域的比特长度为5个比特,MCS1域和MCS2域共占用10个比特。
对于共享域,各个共享域的功能不同,每个共享域承载的信息与数据信道1和数据信道2相关,是这两个数据信道共用的信息。以表7中的频域资源分配(frequency domain resource assignment,FDRA)域为例,FDRA域是共享域,用于承载针对数据信道1和数据信道2的频域信息,或者说,数据信道1和数据信道2的频域信息相同。该频域资源分配域承载的频域信息是针对20MHz的频域资源,该频域资源中的104个RB是用于数据调度的资源,该频域资源分配域占用13个比特。

针对mDCI中的多个域,网络设备可以通过每个载波的载波配置信息配置多个域中每个域的比特长度(即,每个域占用的比特数),终端设备基于每个载波的载波配置信息确定每个域的比特长度,从而,确定mDCI的所有域的比特长度,也就得到了mDCI的原始比特长度,后续,终端设备可以根据mDCI的原始比特长度确定盲检过程中使用的比特长度。对于本申请实施例定义的独立域和共享域,终端设备可以基于载波的载波配置信息采用不同的方式分别确定独立域和共享域的比特长度,以得到mDCI的原始比特长度。
针对M个载波,网络设备为该M个载波配置一一对应的M个载波配置信息,每个载波配置信息用于确定调度信息的比特长度,该调度信息是mDCI的一部分信息,用于调度在每个载波配置信息对应的载波上传输的数据信道,包括各个共享域承载的信息和各个独立域中对应载波的子域承载的信息。
对于独立域,M个载波与每个独立域的M个子域一一对应,M个载波与M个载波配置信息一一对应,所以,M个载波配置信息与每个独立域的M个子域一一对应,每个载波配置信息对应每个独立域的每个子域,每个载波配置信息可用于指示每个独立域的每个子域的比特长度,这样,终端设备可以根据M个载波配置信息确定每个独立域的M个子域的比特长度,从而,确定所有独立域的比特长度。
例如,以表7中的MCS域为例,MCS域是一个独立域,包括两个子域,分别是针对传输块11的MCS1域和针对传输块12的MCS2域,MCS1域对应载波1,MCS2域对应载波2,载波1的载波配置信息指示MCS1域的比特长度为5,载波2的载波配置信息指示MCS2域的比特长度为5,这样,MCS域的比特长度为10。再例如,以表7中的带宽部分指示域为例,带宽部分指示域是一个独立域,包括两个子域,分别是带宽部分指示1域和带宽部分指示2域,带宽部分指示1域对应载波1,带宽部分指示2域对应载波2,载波1的载波配置信息指示带宽部分指示1域的比特长度为1,载波2的载波配置信息指示带宽部分指示2域的比特长度为2,这样,带宽部分指示域的比特长度为3。
对于共享域,每个共享域中承载的信息是在M个载波上传输的M个数据信道共用的信息,所以,每个共享域仅有一个比特长度,可以根据预定义方式最终确定每个共享域的比特长度,该预定义方式与M个载波配置信息中的至少一个载波配置信息相关。
示例性地,根据M个载波配置信息中至少一个载波配置信息确定每个共享域的比特长度。
在一些实施例中,根据M个载波配置信息中的任一个载波配置信息确定每个共享域的比特长度。以表7中的时域资源分配域为例,时域资源分配域是一个共享域,时域资源分配域的比特长度可以是1、2、3或4,无论2个载波的载波配置信息配置的比特长度是否相同,以其中的一个载波的载波配置信息配置的比特长度为准作为时域资源分配域的比特长度。例如,数据信道1对应的载波的载波配置信息配置的比特长度为1,数据信道2 对应的载波的载波配置信息的比特长度为2,以数据信道1对应的载波的载波配置信息配置的比特长度为准,最终确定的时域资源分配域的比特长度为1。
实现过程中,从M个载波中确定一个载波(记为目标载波),将该目标载波的载波配置信息作为用于确定共享域的比特长度的载波配置信息,即为上述的任一个载波配置信息。例如,根据载波的索引号确定目标载波,例如,将最大或最小的索引号对应的载波确定为该目标载波。再例如,将用于发送mDCI的载波确定为目标载波。
在另一些实施例中,根据M个载波配置信息确定每个共享域的比特长度。
在一示例中,根据M个载波配置信息确定目标载波配置信息,将该目标载波配置信息所指示的比特长度作为每个共享域的比特长度,该目标载波配置信息所指示的比特长度是该M个载波配置信息所指示的比特长度中长度最短的比特长度,或,该目标载波配置信息所指示的比特长度是该M个载波配置信息所指示的比特长度中长度最长的比特长度。该示例适用于M个载波配置信息指示的比特长度不完全相同的场景。
以表7中的时域资源分配域为例,时域资源分配域是共享域,用于承载在2个载波上传输的2个数据信道的共用信息,2个载波的载波配置信息分别记为载波配置信息1和载波配置信息2,基于载波配置信息1得到的比特长度为1,基于载波配置信息2得到的比特长度为2,若以最短比特长度作为共享域的比特长度,则时域资源分配域的比特长度为1,若以最长比特长度作为共享域的比特长度,则时域资源分配域的比特长度为2。
在另一示例中,将M个载波配置信息所指示的比特长度之和作为每个共享域的比特长度。继续以表7的时域资源分配域为例,基于载波配置信息1得到的比特长度为1,基于载波配置信息2得到的比特长度为2,最终确定的时域资源分配域的比特长度为3。
这样,终端设备可分别根据不同的方式确定各个共享域和各个独立域的比特长度,最终得到mDCI的原始比特长度,后续,可以根据mDCI的原始比特长度确定盲检过程中使用的比特长度。
可以看出,由于独立域和共享域存在区别,在确定mDCI的原始比特长度时,有必要确定mDCI中哪些域是共享域以及哪些域是独立域,这样,基于不同方式确定独立域和共享域的比特长度。下面,介绍本申请实施例提供的确定独立域和共享域的5种方式。
方式A、预定义共享域和独立域
在该方式中,mDCI中的共享域和独立域都是预定义的,终端设备和网络设备可以基于预定义的方式确定mDCI中哪些域是共享域以及哪些域是独立域。
方式B、预定义和灵活配置共享域和/或独立域
在该方式中,mDCI中存在一部分未被预定义的域,将这些未被定义的域统称为灵活配置的域,该灵活配置的域可以被配置为共享域和/或独立域,网络设备通过信令通知给终端设备,终端设备基于信令确定未预定义的共享域和/或独立域。示例性地,该信令可以是RRC信令、MACCE信令或DCI。下面,分3种情况对该方式做说明。
情况1、预定义一部分共享域和独立域,灵活配置另一部分共享域和独立域
在该情况中,mDCI中的一部分共享域和独立域是预定义的,另一部分共享域和独立域是通过灵活配置的域配置的,且网络设备通过信令发送给终端设备。
假设,mDCI有12个域,其中的3个域被预定义为共享域,另外3个域被预定义为独立域,剩余的6个域是灵活配置的域。在实际传输mDCI中,网络设备将剩余的6个域 中的4个域配置为共享域,其余的2个域配置为独立域,且通过信令将配置的共享域和独立域通知给终端设备,这样,实际传输的mDCI包括7个共享域和5个独立域。终端设备基于预定义的共享域、独立域和信令配置的独立域、共享域,确定mDCI中哪些域是共享域以及哪些域是独立域。
在一示例中,该灵活配置的域可以是默认的独立域,这种灵活配置的域可以被重新配置为共享域,网络设备通过信令通知该终端设备。在上述例子中,剩余的6个灵活配置的域可以是默认的独立域,在实际传输mDCI中,网络设备将6个灵活配置的域中的4个域重新配置为共享域,剩余的2个域是默认的独立域,通过信令将重新配置的4个共享域通知给终端设备,这样,实际传输的mDCI包括7个共享域和5个独立域。
情况2、预定义独立域和部分共享域,灵活配置另一部分共享域
在该情况中,mDCI中的所有独立域都是预定义的,一部分共享域是预定义的,另一部分共享域是网络设备通过灵活配置的域配置的,且通过信令发送给终端设备。
假设,mDCI有12个域,其中的5个域被预定义为独立域以及3个域被预定义为共享域,剩余的4个域是灵活配置的域。在实际传输mDCI中,网络设备将剩余的4个域配置为共享域,且通过信令通知给终端设备。这样,实际传输的mDCI包括5个共享域和7个独立域。
情况3、预定义共享域和部分独立域,灵活配置另一部分独立域
在该情况中,mDCI中的所有共享域都是预定义的,一部分独立域是预定义的,另一部分独立域是网络设备通过灵活配置的域配置的,且通过信令发送给终端设备。
假设,mDCI有12个域,其中的5个域被预定义为共享域以及3个域被预定义为独立域,剩余的4个域是灵活配置的域。在实际传输mDCI中,网络设备将剩余的4个域配置为独立域,且通过信令通知给终端设备。这样,实际传输的mDCI包括5个共享域和7个独立域。
方式C、预定义共享域或预定义和灵活配置共享域,灵活配置独立域
在该方式中,mDCI中的独立域是通过灵活配置的域配置的且通过信令通知给终端设备,mDCI中的共享域是预定义的,或者,共享域是预定义的和通过灵活配置的域配置。
假设,mDCI有10个域,其中的3个域被预定义为共享域,另外7个域是灵活配置的域。例如,在实际传输mDCI中,网络设备将剩余的7个域中的4个域配置为独立域,其余的3个域配置为共享域,且通过信令通知给终端设备,这样,实际传输的mDCI包括6个共享域和4个独立域。再例如,在实际传输mDCI中,网络设备将剩余的7个域都配置为独立域,且通过信令通知给终端设备,这样,实际传输的mDCI包括3个共享域和7个独立域。从而,终端设备基于预定义的共享域和信令配置的域,确定mDCI中哪些域是共享域以及哪些域是独立域。
方式D、预定义独立域或预定义和灵活配置独立域,灵活配置共享域
在该方式中,mDCI中的共享域是通过灵活配置的域配置的且通过信令通知给终端设备,mDCI中的独立域是预定义的,或者,独立域是预定义的和通过灵活配置的域配置。
假设,mDCI有10个域,其中的3个域被预定义为独立域,另外7个域是灵活配置的域。例如,在实际传输mDCI中,网络设备将剩余的7个域中的4个域配置为独立域,其余的3个域配置为共享域,且通过信令通知给终端设备,这样,实际传输的mDCI包括 3个共享域和7个独立域。再例如,在实际传输mDCI中,网络设备将剩余的7个域都配置为共享域,且通过信令通知给终端设备,这样,实际传输的mDCI包括3个独立域和7个共享域。从而,终端设备基于预定义的共享域和信令配置的域,确定mDCI中哪些域是共享域以及哪些域是独立域。
方式E、灵活配置独立域和共享域
在该方式中,无预定义的共享域或独立域,mDCI中的独立域和共享域都通过灵活配置的域配置,且通过信令通知该终端设备,终端设备基于该信令确定哪些域是共享域以及哪些域是独立域。
在一示例中,通过信令配置mDCI中的共享域和独立域。
在另一示例中,通过信令配置mDCI中的共享域,若该信令配置的共享域是mDCI中的一部分域,那么,终端设备可以确定剩余的域为独立域,从而,确定mDCI中的独立域和共享域。
在另一示例中,通过信令配置mDCI中的独立域,若该信令配置的独立域是mDCI中的一部分域,那么,终端设备可以确定剩余的域为共享域,从而,确定mDCI中的独立域和共享域。
mDCI的第二种DCI格式
根据mDCI能够调度的数据信道(或载波)的数量,mDCI中预配置有M组域,一组域对应一个数据信道,每组域包括多个域,每组域相当于一个sDCI中的所有域,用于实现调度一个数据信道的功能。这种格式的的mDCI中的每个域可以理解为上述的独立域,或者,可以理解,这种格式的mDCI,相当于将sDCI中的所有域按照数据信道的数量进行复制。假设,一个sDCI包括24个域,对于mDCI,若mDCI能调度的数据信道的数量是2,mDCI中预配置有2组域,每组域可以包括24个域,该24个域可以相当于一个sDCI的24个域,每组域可用于调度一个数据信道。
对于这种格式的mDCI,每组域中每个域的比特长度根据该组域对应的载波的载波配置信息确定,载波的载波配置信息可用于指示mDCI中对应的每组域中每个域的比特长度。
需要说明的是,第二种DCI格式中的每个域可以理解为上述的独立域。
mDCI的第三种DCI格式
mDCI中包括多个域,每个域中承载的信息是在M个载波上传输的M个数据信道共用的信息。这种格式的mDCI中的每个域都可以理解为上文的共享域,M个数据信道共用每个域,具体描述可参考上文的相关描述。
第二方面、在mDCI和sDCI共存的场景下,确定不同DCI的DCI长度。
如前所述,mDCI用于调度多个载波,sDCI用于调度一个载波,sDCI和mDCI分别具有多种DCI格式。
在一些实施例中,mDCI可以包括两种DCI格式,一种格式用于PDSCH的调度,例如,用DCI format 1_3表示,一种格式用于PUSCH的调度,例如,用DCI format 0_3表示。
在一些实施例中,sDCI可以包括现有或未来定义的任意一种或多种DCI格式,例如,sDCI可以包括以下至少一种格式:DCI format 0_0、DCI format 1_0、DCI format 0_1、DCI format 1_1、DCI format 0_2以及DCI format 1_2。
在sDCI与mDCI共存的场景中,网络设备可以为终端设备配置用于盲检的DCI格式,包括sDCI和mDCI的DCI格式,sDCI具有多种DCI格式,mDCI具有多种DCI格式,sDCI和mDCI的格式也不同,这样,会存多个DCI长度。终端设备需要在一个时间单元(例如,时隙或PDCCH监听时机)内根据DCI长度盲检sDCI与mDCI,而较多的DCI长度会增加盲检复杂度。所以,需要对不同格式的DCI进行对齐操作,减少DCI长度,以减少盲检复杂度。
应理解,网络设备在发送DCI之前,若需要执行对齐操作,通过对齐操作确定DCI长度,采用确定好的DCI长度发送该DCI。终端设备在盲检之前,会采用和网络设备相同的对齐操作确定DCI长度,采用确定好的DCI长度进行盲检,以使得网络设备和终端设备的理解一致,从而得到该DCI。
考虑到DCI长度预算中经过C-RNTI加扰的不同的DCI长度的数量不超过一定数量(例如,3个)的要求,在sDCI与mDCI共存的场景中,本申请提出以下各种实施例,对不同格式的DCI执行对齐操作,以将DCI长度的数量控制在一定数量(例如,3个)以内。
下面,以上述举例的sDCI与mDCI的DCI格式,对各个实施例做详细说明,将经过C-RNTI加扰的不同的DCI长度的数量控制在3个以内。应理解,下面各个实施例中的DCI均为经C-RNTI加扰的DCI,以及,网络设备或终端设备都可以执行下列实施例。
实施例一
在该实施例中,假设,sDCI的4种DCI格式和上述定义的mDCI的2种DCI格式可以共存,即,网络设备配置了6种DCI格式,终端设备可以在同一个时间单元内盲检这6种格式的DCI。网络设备和终端设备按照定义的对齐操作,确定盲检过程中最终采用的DCI长度,将所有DCI的长度控制在3个以内。
在一些实施例中,sDCI的4种DCI格式可以是:DCI format 0_0、DCI format 1_0、DCI format 0_1、DCI format 1_1。
由于DCI format 0_0和DCI format 1_0在CSS和USS中分别具有不同的DCI长度,那么,DCI format 0_0可能具有2个DCI长度,DCI format 1_0也可能具有2个DCI长度,DCI format 0_1、DCI format 1_1、DCI format 0_3、DCI format 1_3在USS中各自具有一个DCI长度,所以,在该实施例中,可能存在8个DCI长度,需要将该8个DCI长度对齐至3个DCI长度以内。
表8示出了实施例一的步骤过程,不同的步骤用于确定不同DCI format的DCI长度,需要执行对齐操作时,将对应的DCI format的DCI长度进行对齐操作,以得到统一的DCI长度。其中,表8中各个步骤对应的DCI长度表示的是经过该步骤后最终得到的DCI长度,DCI长度采用A、B……G等表示,在一个步骤中,DCI长度由一个长度变为另一个长度,采用X1→X2的方式表示,X1和X2可表示不同的DCI长度,也可表示相同的DCI长度,以步骤5A为例,在步骤5A中,DCI长度由B变为A,采用B→A表示。

步骤1、以DCI format 1_0的DCI长度为基准进行对齐,确定CSS中DCI format 0_0的DCI长度和DCI format 1_0的DCI长度。
在该步骤1中,以DCI format 1_0的DCI长度为基准,对CSS中DCI format 0_0执行对齐操作,将DCI format 0_0的DCI长度与DCI format 1_0的DCI长度对齐,使得执行对齐操作后的DCI format 0_0的DCI长度与DCI format 1_0的DCI长度相同,最终得到长度相同的DCI长度,其中,对齐操作可以是补零操作或截短操作。例如,最终得到的长度相同的DCI长度为表8中的A,采用size A表示。
应理解,上述步骤1中最终确定的DCI长度是基于步骤1得到的用于盲检的DCI长度,执行对齐操作之前的DCI长度是DCI的原始比特长度,以对DCI的实际操作为准来理解,若无特殊说明,后续实施例不再赘述。
在一些实施例中,该步骤1的具体过程如下。
步骤1.1、确定CSS中DCI format 0_0的DCI长度(执行对齐操作之前)和CSS中DCI format 1_0的DCI长度。
应理解,该步骤中确定的CSS中DCI format 0_0和DCI format 1_0的DCI长度都是DCI的原始比特长度。CSS中DCI format 0_0的原始比特长度即为上文表1中DCI的信息比特长度,DCI format 0_0中其余的域的长度都是固定的,DCI长度仅与FDRA域有关,DCI format 0_0的FDRA域仅与

步骤1.2、对齐CSS中DCI format 0_0的DCI长度和DCI format 1_0的DCI长度。
图5是本申请实施例提供的对齐CSS中DCI format 0_0的DCI长度与DCI format 1_0的DCI长度的示意图。参考图5中的(a),若CSS中DCI format 0_0的DCI长度(执行补零操作前)比DCI format 1_0的DCI长度小,那么对DCI format 0_0执行补零操作,在 DCI format 0_0后填充零作为padding,使得最终确定的CSS中DCI format 0_0的DCI长度与DCI format 1_0的DCI长度一样。参考图5中的(b),若CSS中DCI format 0_0的DCI长度(执行截短操作前)比DCI format 1_0的DCI长度大,那么打掉DCI format 0_0中FDRA域的高位,使得最终确定的DCI format 0_0的DCI长度和DCI format1_0的DCI长度相同。
步骤2、以DCI format 0_0和DCI format 0_1中DCI长度大的DCI长度作为基准进行对齐,确定USS中DCI format 0_0的DCI长度和DCI format 1_0的DCI长度。
在该步骤2中,以DCI format 0_0和DCI format 0_0中DCI长度大的DCI长度作为基准,对DCI长度小的DCI执行补零操作,将DCI format 0_0的DCI长度与DCI format 1_0的DCI长度对齐,使得最终得到的DCI format 0_0的DCI长度与DCI format 1_0的DCI长度相同,即,得到长度相同的DCI长度。例如,如表8所示,最终得到的长度相同的DCI长度为size B。
在一些实施例中,该步骤2的具体过程如下。
步骤2.1、确定USS中DCI format 0_0的DCI长度和USS中DCI format 1_0的DCI长度。
应理解,该步骤确定的USS中DCI format 0_0和DCI format 1_0的DCI长度都是DCI的原始比特长度。USS中DCI format 0_0的原始比特长度即为上文表1中DCI的信息比特长度,DCI format 0_0中其余的域的长度都是固定的,DCI长度仅与FDRA域有关,DCI format 0_0的FDRA域仅与

步骤2.2、对齐USS中DCI format 0_0的DCI长度和DCI format 1_0的DCI长度。
在步骤中,分为以下三种情况对DCI format 0_0和DCI format 1_0做不同处理,以确定两个DCI的DCI长度。
若网络设备为终端设备配置了增补上行(supplementary uplink,SUL)载波,PUSCH可以在SUL和non-SUL上发送,若调度SUL和non-SUL的USS中的DCI format 0_0的DCI长度不相等,则需要将DCI长度大的DCI长度作为基准,对DCI长度小的DCI format 0-0执行补零操作,使得调度SUL和non-SUL的USS中的DCI format 0_0的DCI长度相等。具体地,参考图6中的(a),若USS中用于调度SUL载波的DCI format 0_0(记为DCI format 0_0 SUL)比用于调度non SUL载波的DCI format 0_0(记为DCI format 0_0 non SUL)的DCI长度小,则对DCI format 0_0 SUL执行补零操作,在DCI format 0_0 SUL后填充零,使得DCI format 0_0 SUL的DCI长度和DCI format 0_0non SUL的DCI长度相同。参考图6中的(b),若USS中DCI format 0_0 non SUL比DCI format 0_0 SUL的DCI长度小,则对DCI format 0_0 non SUL执行补零操作,在DCI format 0_0 non SUL后填充零,使得DCI format 0_0 non SUL的DCI长度和DCI format 0_0 SUL的DCI长度相同。
需要说明的是,若网络设备为终端设备配置了SUL载波,网络设备在为特定终端设备配置DCI format 0_0时,通过DCIformat 0_0仅调度SUL载波和non_SUL载波中的一 个。所以,在该实施例中,网络设备为特定终端设备仅配置了一个DCI format 0_0,该DCI format 0_0用于调度SUL载波或non_SUL载波。后续关于网络设备为终端设备配置SUL载波的情况下将DCI长度对齐的解释同此处,不再赘述。
参考图6中的(c),若USS中DCI format 1_0的DCI长度(执行补零操作之前)比DCI format 0_0的DCI长度小,那么对DCI format 1_0执行补零操作,在DCI format 1_0后填充零作为padding,使得最终确定的USS中DCI format 0_0的DCI长度与DCI format 1_0的DCI长度相同。
参考图6中的(d),若USS中DCI format 0_0的DCI长度(执行补零操作前)比DCI format 1_0的DCI长度小,那么对DCI format 0_0执行补零操作,在DCI format 0_0后填充零作为padding,使得最终确定的USS中DCI format 0_0的DCI长度与DCI format 1_0的DCI长度相同。
步骤3A、确定DCI format 0_1的DCI长度和DCI format 1_1的DCI长度。
该步骤确定的DCI format 0_1的DCI长度和DCI format 1_1的DCI长度可以是DCI的原始比特长度,也可以是执行对齐操作后的比特长度,确定的这两个DCI的DCI长度可以相同,也可以不同。例如,如表8所示,确定的DCI format 0_1的DCI长度为size C,确定的DCI format 1_1的DCI长度为size D,C与D可相同,也可不同。
在该步骤中,分为以下三种情况对DCI format 0_1和DCI format 1_1做不同处理,以确定两个DCI的DCI长度。
若网络设备为终端设备配置了SUL载波,PUSCH可以在SUL和non-SUL上发送,若调度SUL和non-SUL的USS中的DCI format 0_1的DCI长度不相等,则需要将DCI长度大的DCI长度作为基准,对DCI长度小的DCI format 0_1执行补零操作,使得调度SUL和non-SUL的USS中的DCI format 0_1的DCI长度相等。该过程的具体描述可参考步骤2中关于图6中的(a)和(b)的相关描述,将DCI format 0_0替换为DCI format 0_1即可,不再赘述。
参考图7中的(a),若终端设备在USS中的DCI format 0_1和另外一个终端设备在USS的DCI format 0_0或DCI format 1_0的DCI长度相同,则对DCI format 0_1执行补零操作,在DCI format 0_1后填充1个零比特(bit)。在这种情况下,表8中的size C是对DCI format 0_1执行补零操作后的DCI长度。
参考图7中的(b),若终端设备在USS中的DCI format 1_1和另外一个终端设备在USS的DCI format 0_0或DCI format 1_0的DCI长度相同,则对DCI format 1_1执行补零操作,在DCI format 1_1后填充1个零比特(bit)。在这种情况下,表8中的size D是对DCI format 1_1执行补零操作后的DCI长度。
步骤3B、确定DCI format 0_3的DCI长度和DCI format 1_3的DCI长度
在该步骤中,确定的DCI format 1_3的DCI长度是原始比特长度,确定的DCI format 0_3的DCI长度可以是DCI的原始比特长度,也可以是执行对齐操作后的比特长度,具体与网络设备是否为终端设备配置SUL载波有关。
若网络设备未为终端设备配置SUL载波,则确定的DCI format 0_3的DCI长度是原始比特长度。
若网络设备为终端设备配置了SUL载波,PUSCH可以在SUL和non-SUL上发送, 若调度SUL和non-SUL的USS中的DCI format 0_3的DCI长度不相等,则需要将DCI长度大的DCI长度作为基准,对DCI长度小的DCI format 0_3执行补零操作,使得调度SUL和non-SUL的USS中的DCI format 0_3的DCI长度相等。该过程的具体描述可参考步骤2中关于图6中的(a)和(b)的相关描述,将DCI format 0_0替换为DCI format 0_3即可,不再赘述。在该情况中,若网络设备为该终端设备配置的DCI format 0_3是长度小的DCI,则为该终端设备确定的DCI format 0_3的DCI长度是执行补零操作后的DCI长度,若网络设备为该终端设备配置的DCI format 0_3是长度大的DCI,则不需要对长度大的DCI format 0_3执行补零操作,则确定的DCI format 0_3的DCI长度是原始比特长度。
在该步骤中,最终确定的DCI format 0_3的DCI长度和DCI format 1_3的DCI长度可以相同,也可以不同。例如,如表8所示,确定的DCI format 0_3的DCI长度为size E,确定的DCI format 1_3的DCI长度size F,E与F可相同,也可不同。
应理解,本申请实施例对上述步骤1-步骤3B的执行顺序不做任何限定,但步骤1-步骤3B需在步骤4之前执行。
步骤4、判断上述确定的DCI是否满足DCI长度预算。
若经过上述步骤1-步骤3B得到的DCI长度的数量满足DCI长度预算,则将上述步骤1-步骤3B确定的DCI长度作为盲检过程中最终采用的DCI长度,若不满足DCI长度预算,则继续执行步骤5A-5C。
假设,经过步骤1-步骤3B得到的DCI长度包括:size A、size B、size C、size D、size E、size F,若各个DCI长度都不相同,则DCI长度的数量为6个,大于3,不满足DCI长度预算,继续执行步骤5A-5C。
需要说明的是,在上述步骤1-步骤3B中,可以不做DCI长度预算的计算,即终端设备或网络设备可以不统计不同DCI长度的个数,在执行完步骤1-步骤3B之后再统计。
步骤5A、重新确定USS中DCI format 0_0的DCI长度和DCI format 1_0的DCI长度。
在该步骤中,重新确定的USS中DCI format 0_0的DCI长度和DCI format 1_0的DCI长度相同,且与步骤1中得到的USS中DCI format 0_0的DCI长度和DCI format 1_0的DCI长度相同。如表8所示,该步骤最终得到的USS中DCI format 0_0的DCI长度和DCI format 1_0的DCI长度由之前的size B变为size A。
该步骤的具体过程如下。
步骤5A.1、若步骤3A中对DCI format 0_1和DCI format 1_1执行如图7所示的补零操作,需去除步骤3A中为DCI format 0_1和DCI format 1_1增加的1比特填充。
因为步骤3A中对DCI format 0_1和DCI format 1_1执行补零操作,是为了与另一个终端设备在USS的DCI format 0_0或DCI format 1_0的DCI长度区分,现在需要重新确定DCI format 0_0和DCI format 1_0的DCI长度,重新确定的DCI长度与另一个终端设备在USS的DCI format 0_0或DCI format 1_0的DCI长度是不同的,所以,没有必要保留步骤3A中对DCI format 0_1和DCI format 1_1执行补零操作的DCI长度,将添加的1比特删除即可。
步骤5A.2、确定USS中DCI format 0_0的DCI长度和USS中DCI format 1_0的DCI长度。
应理解,该步骤确定的USS中DCI format 0_0和DCI format 1_0的DCI长度都是DCI 的原始比特长度。USS中DCI format 0_0的原始比特长度即为上文表1中DCI的信息比特长度,DCI format 0_0中其余的域的长度都是固定的,DCI长度仅与FDRA域有关,DCI format 0_0的FDRA域仅与

步骤5A.3、对齐USS中DCI format 0_0的DCI长度和DCI format 1_0的DCI长度。
以图5为例,参考图5中的(a),若USS中DCI format 0_0的DCI长度(执行补零操作前)比DCI format 1_0的DCI长度小,那么对DCI format 0_0执行补零操作,在DCI format 0_0后填充零作为padding,使得最终确定的USS中DCI format 0_0的DCI长度与DCIformat 1_0的DCI长度一样。参考图5中的(b),若USS中DCI format 0_0的DCI长度(执行截短操作前)比DCI format 1_0的DCI长度大,那么打掉DCI format 0_0中FDRA域的高位,使得最终确定的DCI format 0_0的DCI长度和DCI format1_0的DCI长度相同。
经过步骤5A后,减少了一个DCI长度,继续判断上述确定的DCI是否满足DCI长度预算,若经过上述步骤1-步骤5A得到的DCI长度的数量满足DCI长度预算,则将上述步骤1-步骤5A确定的DCI长度作为盲检过程的DCI长度,若不满足DCI长度预算,则继续执行步骤5B-5C。
假设,经过步骤5A后,得到的DCI长度包括:size A、size C、size D、size E、size F,若各个DCI长度都不相同,则DCI长度的数量为5,大于3,不满足DCI长度预算,执行步骤5B-5C。
步骤5B、重新确定DCI format 0_3的DCI长度和DCI format 1_3的DCI长度。
在该步骤中,将DCI format 0_3的DCI长度和DCI format 1_3的DCI长度对齐,使得最终得到的DCI format 0_3的DCI长度与DCI format 1_3的DCI长度相同,即,得到长度相同的DCI长度。例如,如表8所示,经过步骤5B最终得到的DCI format 0_3的DCI长度由之前的size E变为size G,经过步骤5B最终得到的DCI format 1_3的DCI长度由之前的size F变为size G。
在一些实施例中,可以以DCI format 0_3和DCI format 1_3中DCI长度大的DCI长度作为基准,对另一个DCI长度小的DCI执行补零操作,将两个DCI长度变为一个DCI长度。
参考图8中的(a),若DCI format 1_3的DCI长度(执行补零操作之前)比DCI format 0_3的DCI长度小,那么对DCI format 1_3执行补零操作,在DCI format 1_3后填充零作为padding,使得最终确定的USS中DCI format 0_3的DCI长度与DCI format 1_3的DCI长度相同。在该情况中,表8中的size G即为size E。
参考图8中的(b),若DCI format 0_3的DCI长度(执行补零操作前)比DCI format 1_3的DCI长度小,那么对DCI format 0_3执行补零操作,在DCI format 0_3后填充零作为padding,使得最终确定的USS中DCI format 0_3的DCI长度与DCI format 1_3的DCI长度相同。在该情况中,表8中的size G即为size F。
应理解,上述以DCI format 0_3和DCI format 1_3中DCI长度大的作为基准将两个DCI长度拉齐的方式仅为示意性说明,任何能够对齐DCI format 0_3和DCI format 1_3的DCI长度的方法都可行。例如,可以将DCI format 0_3和DCI format 1_3中任一个的DCI长度作为基准,对另一个DCI执行对齐操作(补零操作或截短操作),以将两个DCI长度对齐,将两个DCI长度变为一个DCI长度。
经过步骤5B后,再次减少了一个DCI长度,继续判断上述确定的DCI是否满足DCI长度预算,若经过上述步骤1-步骤5B得到的DCI长度的数量满足DCI长度预算,则将上述步骤1-步骤5B确定的DCI长度作为盲检过程中最终采用的DCI长度,若不满足DCI长度预算,则继续执行步骤5C。
假设,经过步骤5B后,得到的DCI长度包括:size A、size C、size D、size G,若各个DCI长度都不相同,则DCI长度的数量为4,大于3,不满足DCI长度预算,执行步骤5C。
步骤5C、重新确定DCI format 0_1的DCI长度和DCI format 1_1的DCI长度。
在该步骤中,将DCI format 0_1的DCI长度和DCI format 1_1的DCI长度对齐,使得最终得到的DCI format 0_1的DCI长度与DCI format 1_1的DCI长度相同,即,得到长度相同的DCI长度。例如,如表8所示,经过步骤5C最终得到的DCI format 0_1的DCI长度由之前的size C变为size H,经过步骤5C最终得到的DCI format 1_1的DCI长度由之前的size D变为size H。
在一些实施例中,可以以DCI format 0_1和DCI format 1_1中DCI长度大的DCI长度作为基准,对另一个DCI长度小的DCI执行补零操作,将两个DCI长度变为一个DCI长度。
参考图9中的(a),若DCI format 1_1的DCI长度(执行补零操作之前)比DCI format 0_1的DCI长度小,那么对DCI format 1_1执行补零操作,在DCI format 1_1后填充零作为padding,使得最终确定的USS中DCI format 0_1的DCI长度与DCI format 1_1的DCI长度相同。在该情况中,表8中的size C即为size H。
参考图9中的(b),若DCI format 0_1的DCI长度(执行补零操作前)比DCI format 1_1的DCI长度小,那么对DCI format 0_1执行补零操作,在DCI format 0_1后填充零作为padding,使得最终确定的USS中DCI format 0_1的DCI长度与DCI format 1-1的DCI长度相同。在该情况中,表8中的size D即为size F。
应理解,上述以DCI format 0_1和DCI format 1_1中DCI长度大的作为基准将两个DCI长度拉齐的方式仅为示意性说明,任何能够对齐DCI format 0_1和DCI format 1_1的DCI长度的方法都可行。例如,可以将DCI format 0_1和DCI format 1_1中任一个的DCI长度作为基准,对另一个DCI执行对齐操作(补零操作或截短操作),以将两个DCI长度对齐,将两个DCI长度变为一个DCI长度。
经过步骤5C后,再次减少了一个DCI长度,继续判断上述确定的DCI是否满足DCI长度预算,若经过上述步骤1-步骤5C得到的DCI长度的数量满足DCI长度预算,则将上述步骤1-步骤5C确定的DCI长度作为盲检过程中最终采用的DCI长度。
假设,经过步骤5C后,得到的DCI长度包括:size A、size G、size H,若各个DCI长度都不相同,则DCI长度的数量为3,满足DCI长度预算,那么,size A、size G、size  H则为盲检过程中最终采用的DCI长度,终端设备分别采用size A、size G、size H对DCI进行盲检,以获得网络设备发送的DCI。
应理解,本申请实施例对上述步骤5A-步骤5C的执行顺序不做任何限定,上述执行顺序仅为示意性说明。例如,步骤5B可在步骤5C之后执行,再例如,步骤5B可在步骤5A和5C之前执行。
还应理解,上述实施例一采用的sDCI的4种DCI格式(即,DCI format 0_0、DCI format 1_0、DCI format 0_1、DCI format 1_1)仅为示意性说明,本申请实施例不做任何限定。例如,sDCI的4种DCI格式还可以是:DCI format 0_0、DCI format 1_0、DCI format 0_2、DCI format 1_2,将步骤3A替换为确定DCI format 0_2和DCI format 1_2的DCI长度,将步骤5C替换为重新确定DCI format 0_2和DCI format 1_2的DCI长度即可,关于这两个步骤中如何确定DCI长度的过程可参考下文实施例二的步骤3B和步骤5B的相关描述,不再赘述。
本申请实施例提供的多载波调度的方法,在sDCI和mDCI共存场景下,限制与mDCI共存的sDCI的DCI格式,减少了这种场景下可能存在的DCI格式的数量,可以减少由于确定DCI长度过程中可能执行的较多的对齐操作而占用的时长,以减少处理时延,降低复杂度。
此外,由于DCI format 0_1与DCI format 1_1是调度过程中最常用的DCI格式,所以,在终端设备需要在一个时间单元内盲检包括DCI format 0_1与DCI format 1_1在内的多个DCI时,先对齐其他的例如DCI format 0_3和DCI format 1_3的DCI长度,后对齐DCI format 0_1与DCI format 1_1的DCI长度,对于不需要对齐DCI format 0_1与DCI format 1_1的DCI长度就可以满足DCI长度预算的情况下,可以减少处理时延和实现复杂度。
如前所述,在通过mDCI调度多个载波的方案中,mDCI可通过两种调度方式调度多个载波,即,在第一种调度方式中,如图3所示,DCI通过调度多个数据信道来调度多个载波,在第二种调度方式中,如图4所示,DCI通过调度一个数据信道来调度多个载波。上述实施例一可以适用于任意一种调度方式,本申请实施例不做任何限定,不过,从通信开销的角度考度,实施例一更节省通信开销。
原因在于,第一种调度方式对应的mDCI需要调度多个数据信道,用于传输每个数据信道的相关信息都通过mDCI指示,所以,第一种调度方式对应的mDCI与sDCI相差很大,最直观的体现就是mDCI的DCI长度与sDCI的DCI长度相差很大,mDCI的DCI长度比较大。若是将mDCI中多个DCI格式的DCI长度与sDCI中多个DCI格式的DCI长度对齐,很可能会增加大量比特开销,例如,mDCI中DCI format 0_3的DCI长度为100个比特,sDCI的DCI format 0_0的DCI长度是50个比特,在一种可能对齐方式中,需要将50个比特填充至100个比特,这样,增加了大量开销。上述实施例一,在sDCI和mDCI可共存场景下,限制与mDCI共存的sDCI中的DCI格式,在需要对齐mDCI中DCI的DCI长度的情况下,仅需要将mDCI中的DCI的DCI长度对齐即可,不需要将mDCI的DCI长度与sDCI的DCI长度对齐,避免了将mDCI的DCI长度与sDCI的DCI长度对齐过程中可能增加的大量开销。
实施例二
在该实施例中,假设,sDCI的6种DCI格式和上述定义的mDCI的2种DCI格式可以共存,即,网络设备配置了8种DCI格式,终端设备可以在同一个时间单元内盲检这8种格式的DCI。网络设备和终端设备按照定义的对齐操作,确定盲检过程中最终采用的DCI长度,将所有DCI的长度控制在3个以内。
在一些实施例中,sDCI的6种DCI格式可以是:DCI format 0_0、DCI format 1_0、DCI format 0_1、DCI format 1_1、DCI format 0_2、DCI format 1_2。
由于DCI format 0_0和DCI format 1_0在CSS和USS中分别具有不同的DCI长度,那么,DCI format 0_0可能具有2个DCI长度,DCI format 1_0也可能具有2个DCI长度,DCI format 0_1、DCI format 1_1、DCI format 0_2、DCI format 1_2、DCI format 0_3、DCI format 1_3在USS中各自具有一个DCI长度,所以,在该实施例中,可能存在10个DCI长度,需要将该10个DCI长度控制在3个DCI长度以内。
表9示出了实施例二的步骤过程,关于表9的说明可参考上文对表8的说明,不再赘述。

步骤1、以DCI format 1_0的DCI长度为基准进行对齐,确定CSS中DCI format 0_0的DCI长度和DCI format 1_0的DCI长度。例如,如表9所示,确定的DCI长度为size A。
步骤2、以DCI format 0_0和DCI format 0_1中DCI长度大的DCI长度作为基准进行对齐,确定USS中DCI format 0_0的DCI长度和DCI format 1_0的DCI长度。例如,如表9所示,确定的DCI长度为size B。
步骤3A、确定DCI format 0_1的DCI长度和DCI format 1_1的DCI长度。例如,如表9所示,确定的USS中DCI format 0_1的DCI长度为size C、确定的USS中DCI format 1_1的DCI长度为size D。
关于步骤1-步骤3A的具体描述可分别参考实施例一中关于上述3个步骤的相关描述,不再赘述。
步骤3B、确定DCI format 0_2的DCI长度和DCI format 1_2的DCI长度。
在该步骤中,确定的DCI format 1_2的DCI长度是原始比特长度,确定的DCI format 0_2的DCI长度可以是DCI的原始比特长度,也可以是执行对齐操作后的比特长度,具体与网络设备是否为终端设备配置SUL载波有关。
若网络设备未为终端设备配置SUL载波,则确定的DCI format 0_2的DCI长度是原始比特长度。
若网络设备为终端设备配置了SUL载波,PUSCH可以在SUL和non-SUL上发送,若调度SUL和non-SUL的USS中的DCI format 0_2的DCI长度不相等,则需要将DCI长度大的DCI长度作为基准,对DCI长度小的DCI format 0_2执行补零操作,使得调度SUL和non-SUL的USS中的DCI format 0_2的DCI长度相等。该过程的具体描述可参考步骤2中关于图6中的(a)和(b)的相关描述,将DCI format 0_0替换为DCI format 0_2即可,不再赘述。在该情况中,若网络设备为该终端设备配置的DCI format 0_2是长度小的DCI,则为该终端设备确定的DCI format 0_2的DCI长度是执行补零操作后的DCI长度,若网络设备为该终端设备配置的DCI format 0_2是长度大的DCI,则不需要对长度大的DCI format 0_2执行补零操作,则确定的DCI format 0_2的DCI长度是原始比特长度。
在该步骤中,最终确定的DCI format 0_2的DCI长度和DCI format 1_2的DCI长度可以相同,也可以不同。例如,如表9所示,确定的DCI format 0_2的DCI长度为size M,确定的DCI format 1_2的DCI长度size N,M与N可相同,也可不同。
步骤3C、确定DCI format 0_3的DCI长度和DCI format 1_3的DCI长度。例如,如表9所示,确定的USS中DCI format 0_3的DCI长度为size E、确定的USS中DCI format 1_3的DCI长度为size F。
关于步骤3C的具体描述可参考实施例一的步骤3B的相关描述,不再赘述。
应理解,本申请实施例对上述步骤1-步骤3C的执行顺序不做任何限定,但步骤1-步骤3C需在步骤4之前执行。
步骤4、判断上述确定的DCI是否满足DCI长度预算。
若经过上述步骤1-步骤3C得到的DCI长度的数量满足DCI长度预算,则将上述步骤1-步骤3C确定的DCI长度作为盲检过程中最终采用的DCI长度,若不满足DCI长度预算,则继续执行步骤5A-5E。
假设,经过步骤1-步骤3C得到的DCI长度包括:size A、size B、size C、size D、size  E、size F、size M、size N。若各个DCI长度都不相同,则DCI长度的数量为8个,大于3,不满足DCI长度预算,继续执行步骤5A-5E。
需要说明的是,在上述步骤1-步骤3C中,可以不做DCI长度预算的计算,即终端设备或网络设备可以不统计不同DCI长度的个数,在执行完步骤1-步骤3C之后再统计。
步骤5A、重新确定USS中DCI format 0_0的DCI长度和DCI format 1_0的DCI长度。例如,如表9所示,该步骤最终得到的USS中DCI format 0_0的DCI长度和DCI format 1_0的DCI长度由之前的size B变为size A。
关于步骤5A的具体描述可参考实施例一关于步骤5A的相关描述,不再赘述。
步骤5B、重新确定DCI format 0_2的DCI长度和DCI format 1_2的DCI长度。
在该步骤中,将DCI format 0_2的DCI长度和DCI format 1_2的DCI长度对齐,使得最终得到的DCI format 0_2的DCI长度与DCI format 1_2的DCI长度相同,即,得到长度相同的DCI长度。例如,如表9所示,经过步骤5B最终得到的DCI format 0_2的DCI长度由之前的size M变为size K,经过步骤5B最终得到的DCI format 1_2的DCI长度由之前的size N变为size K。
在一些实施例中,可以以DCI format 0_2和DCI format 1_2中DCI长度大的DCI长度作为基准,对另一个DCI长度小的DCI执行补零操作,将两个DCI长度变为一个DCI长度。
参考图10中的(a),若DCI format 1_2的DCI长度(执行补零操作之前)比DCI format 0_2的DCI长度小,那么对DCI format 1_2执行补零操作,在DCI format 1_2后填充零作为padding,使得最终确定的USS中DCI format 0_2的DCI长度与DCI format 1_2的DCI长度相同。在该情况中,表9中的size K即为size M。
参考图10中的(b),若DCI format 0_2的DCI长度(执行补零操作前)比DCI format 1_2的DCI长度小,那么对DCI format 0_2执行补零操作,在DCI format 0_2后填充零作为padding,使得最终确定的USS中DCI format 0_2的DCI长度与DCI format 1_2的DCI长度相同。在该情况中,表9中的size K即为size N。
应理解,上述以DCI format 0_2和DCI format 1_2中DCI长度大的作为基准将两个DCI长度拉齐的方式仅为示意性说明,任何能够对齐DCI format 0_2和DCI format 1_2的DCI长度的方法都可行。例如,可以将DCI format 0_2和DCI format 1_2中任一个的DCI长度作为基准,对另一个DCI执行对齐操作(补零操作或截短操作),以将两个DCI长度对齐,将两个DCI长度变为一个DCI长度。
经过步骤5B后,再次减少了一个DCI长度,假设,经过步骤5B后,得到的DCI长度包括:size A、size C、size D、size K、size E、size F,若各个DCI长度都不相同,则DCI长度的数量为6,大于3,不满足DCI长度预算,执行步骤5C。
步骤5C、重新确定DCI format 0_1的DCI长度和DCI format 1_1的DCI长度。例如,如表9所示,经过步骤5C最终得到的DCI format 0_1的DCI长度由之前的size C变为size H,经过步骤5C最终得到的DCI format 1_1的DCI长度由之前的size D变为size H。
关于步骤5C的具体描述可参考实施一中关于步骤5C的相关描述,不再赘述。
经过步骤5C后,再次减少了一个DCI长度,假设,经过步骤5C后,得到的DCI长度包括:size A、size H、size K、size E、size F,若各个DCI长度都不相同,则DCI长度 的数量为5,大于3,不满足DCI长度预算,执行步骤5D。
步骤5D、重新确定DCI format 0_3的DCI长度和DCI format 1_3的DC长度。例如,如表9所示,经过步骤5D最终得到的DCI format 0_3的DCI长度由之前的size E变为size G,经过步骤5D最终得到的DCI format 1_3的DCI长度由之前的size F变为size G。
关于步骤5D的具体描述可参考上文的相关描述,不再赘述。
经过步骤5D后,再次减少了一个DCI长度,假设,经过步骤5D后,得到的DCI长度包括:size A、size H、size K、size G,若各个DCI长度都不相同,则DCI长度的数量为5,大于3,不满足DCI长度预算,执行步骤5E。
步骤5E、对齐DCI format 0_3、DCI format 1_3与CSS和USS中DCI format 0_0、DCI format 1_0的DCI长度。
由于在步骤5E之前,已经对齐了DCI format 0_3、DCI format 1_3的DCI长度,以及对齐了USS和CSS中DCI format 0_0、DCI format 1_0的DCI长度,所以,在该步骤中,这4个DCI格式仅有2个DCI长度,只需要将这2个DCI长度对齐为一个DCI长度即可。例如,如表9所示,经过步骤5E最终得到的DCI format 0_3、DCI format 1_3的DCI长度由之前的size G变为size L1,经过步骤5E最终得到的USS和CSS的DCI format 0_0、DCI format 1_0的DCI长度由之前的size A变为size L1。
在一些实施例中,可以以DCI format 0_3和DCI format 1_3的DCI长度(例如,size G)与DCI format 0_0和DCI format 1_0的DCI长度(例如,size A)中DCI长度大的DCI长度作为基准,对其余DCI长度小的DCI执行补零操作,将两个DCI长度变为一个DCI长度。
若DCI format 0_0和DCI format 1_0的DCI长度(例如,size A)比DCI format 0_3和DCI format 1_3的DCI长度(例如,size G)小,那么对DCI format 0_0和DCI format 1_0执行相同的补零操作,在DCI format 0_0和DCI format 1_0后填充零作为padding,使得最终确定的DCI format 0_0和DCI format 1_0的DCI长度与DCI format 0_3和DCI format 1_3的DCI长度相同。在该情况中,表9中的size L1即为size G。
若DCI format 0_3和DCI format 1_3的DCI长度(例如,size G)比DCI format 0_0和DCI format 1_0的DCI长度(例如,size A)小,那么对DCI format 0_3和DCI format 1_3执行相同的补零操作,在DCI format 0_3和DCI format 1_3后填充零作为padding,使得最终确定的DCI format 0_0和DCI format 1_0的DCI长度与DCI format 0_3和DCI format 1_3的DCI长度相同。在该情况中,表9中的size L1即为size A。
应理解,上述以DCI format 0_3和DCI format 1_3的DCI长度(例如,size G)与DCI format 0_0和DCI format 1_0的DCI长度(例如,size A)中DCI长度大的DCI长度作为基准将两个DCI长度拉齐的方式仅为示意性说明,任何能够对齐上述4个DCI的DCI长度的方法都可行。例如,可以将DCI format 0_3和DCI format 1_3的DCI长度(例如,size G)与DCI format 0_0和DCI format 1_0的DCI长度(例如,size A)中任一个的DCI长度作为基准,对其余两个DCI执行相同的对齐操作(补零操作或截短操作),以将两个DCI长度对齐,将两个DCI长度变为一个DCI长度。
经过步骤5E后,再次减少了一个DCI长度,继续判断上述确定的DCI是否满足DCI长度预算,若经过上述步骤1-步骤5E得到的DCI长度的数量满足DCI长度预算,则将上 述步骤1-步骤5E确定的DCI长度作为盲检过程中最终采用的DCI长度。
假设,经过步骤5E后,得到的DCI长度包括:size L1、size H、size K,若各个DCI长度都不相同,则DCI长度的数量为3,满足DCI长度预算,那么,size L1、size H、size K则为盲检过程中最终采用的DCI长度,终端设备分别采用size L1、size H、size K对DCI进行盲检,以获得网络设备发送的DCI。
应理解,本申请实施例对上述步骤5A-步骤5E的执行顺序不做任何限定,上述执行顺序仅为示意性说明。
本申请实施例提供的多载波调度的方法,在sDCI和mDCI共存场景下,通过将同系列(例如,DCI format x_0、DCI format x_1、DCI format x_2或DCI format x_3)的DCI长度对齐后,以及,将DCI format x_3与DCI format x_0的DCI长度对齐,使得DCI长度的数量控制在3,满足DCI长度预算,减少了盲检复杂度,提高了系统传输性能。
实施例三
该实施例与实施例二定义可共存的mDCI和sDCI的DCI格式相同,可共存的mDCI和sDCI的DCI格式如表10所示,包括:CSS中的DCI format 0_0、CSS中的DCI format 1_0、USS中的DCI format 0_0、USS中的DCI format 1_0、DCI format 0_1、DCI format 1_1、DCI format 0_2、DCI format 1_2、DCI format 0_3、DCI format 1_3,上述8种DCI格式可能存在10个DCI长度,需要将该10个DCI长度控制在3个DCI长度以内。实施例三与实施例二不同之处在于,步骤5E中将DCI format 0_2、DCI format 1_2与CSS和USS中DCI format 0_0、DCI format 1_0的DCI长度对齐。

上述步骤1-步骤5D的过程分别与实施例一的步骤1-步骤5D的过程都相同,因此,关于步骤1-步骤5D的具体描述可分别参考实施例二中关于各个步骤的相关描述,不再赘述。
步骤5E、对齐DCI format 0_2、DCI format 1_2与CSS和USS中DCI format 0_0、DCI format 1_0的DCI长度。
由于在步骤5E之前,已经对齐了DCI format 0_2、DCI format 1_2的DCI长度,以及对齐了USS和CSS中DCI format 0_0、DCI format 1_0的DCI长度,所以,在该步骤中,这4个DCI格式仅有2个DCI长度,只需要将这2个DCI长度对齐为一个DCI长度即可。例如,如表10所示,经过步骤5E最终得到的DCI format 0_2、DCI format 1_2的DCI长度由之前的size K变为size L2,经过步骤5E最终得到的USS和CSS的DCI format 0_0、DCI format 1_0的DCI长度由之前的size A变为size L2。
在一些实施例中,可以以DCI format 0_2和DCI format 1_2的DCI长度(例如,size K)与DCI format 0_0和DCI format 1_0的DCI长度(例如,size A)中DCI长度大的DCI长度作为基准,对其余DCI长度小的DCI执行补零操作,将两个DCI长度变为一个DCI长度。
若DCI format 0_0和DCI format 1_0的DCI长度(例如,size A)比DCI format 0_2和DCI format 1_2的DCI长度(例如,size K)小,那么对DCI format 0_0和DCI format 1_0执行相同的补零操作,在DCI format 0_0和DCI format 1_0后填充零作为padding,使得最终确定的DCI format 0_0和DCI format 1_0的DCI长度与DCI format 0_2和DCI format 1_2的DCI长度相同。在该情况中,表10中的size L2即为size K。
若DCI format 0_2和DCI format 1_2的DCI长度(例如,size K)比DCI format 0_0和DCI format 1_0的DCI长度(例如,size A)小,那么对DCI format 0_2和DCI format 1_2 执行相同的补零操作,在DCI format 0_2和DCI format 1_2后填充零作为padding,使得最终确定的DCI format 0_0和DCI format 1_0的DCI长度与DCI format 0_3和DCI format 1_3的DCI长度相同。在该情况中,表10中的size L2即为size A。
应理解,上述以DCI format 0_2和DCI format 1_2的DCI长度(例如,size K)与DCI format 0_0和DCI format 1_0的DCI长度(例如,size A)中DCI长度大的DCI长度作为基准将两个DCI长度拉齐的方式仅为示意性说明,任何能够对齐上述4个DCI的DCI长度的方法都可行。例如,可以将DCI format 0_2和DCI format 1_2的DCI长度(例如,size K)与DCI format 0_0和DCI format 1_0的DCI长度(例如,size A)中任一个的DCI长度作为基准,对其余两个DCI执行相同的对齐操作(补零操作或截短操作),以将两个DCI长度对齐,将两个DCI长度变为一个DCI长度。
经过步骤5E后,再次减少了一个DCI长度,继续判断上述确定的DCI是否满足DCI长度预算,若经过上述步骤1-步骤5E得到的DCI长度的数量满足DCI长度预算,则将上述步骤1-步骤5E确定的DCI长度作为盲检过程中最终采用的DCI长度。
假设,经过步骤5E后,得到的DCI长度包括:size L2、size H、size G,若各个DCI长度都不相同,则DCI长度的数量为3,满足DCI长度预算,那么,size L2、size H、size G则为盲检过程中最终采用的DCI长度,终端设备分别采用size L2、size H、size G对DCI进行盲检,以获得网络设备发送的DCI。
应理解,本申请实施例对上述步骤5A-步骤5E的执行顺序不做任何限定,上述执行顺序仅为示意性说明。
本申请实施例提供的多载波调度的方法,在sDCI和mDCI共存场景下,通过将同系列(例如,DCI format x_0、DCI format x_1、DCI format x_2或DCI format x_3)的DCI长度对齐后,以及,将DCI format x_2与DCI format x_0的DCI长度对齐,使得DCI长度的数量控制在3,满足DCI长度预算,减少了盲检复杂度,提高了系统传输性能。并且,由于DCI format x_2与DCI format x_0的DCI长度相差不大,将DCI format x_2与DCI format x_0的DCI长度对齐的过程中,在需要以DCI format x_2对应的DCI长度和DCI format x_0对应的DCI长度中的一个DCI长度作为基准,对另一系列DCI对应的DCI长度执行补零操作的情况下,不会增加较多的比特数,可以避免DCI长度对齐过程中可能增加的大量开销的问题。
实施例四
该实施例与实施例二定义可共存的mDCI和sDCI的DCI格式相同,可共存的mDCI和sDCI的DCI格式如表11所示,包括:CSS中的DCI format 0_0、CSS中的DCI format 1_0、USS中的DCI format 0_0、USS中的DCI format 1_0、DCI format 0_1、DCI format 1_1、DCI format 0_2、DCI format 1_2、DCI format 0_3、DCI format 1_3,上述8种DCI格式可能存在10个DCI长度,需要将该10个DCI长度控制在3个DCI长度以内。实施例四与实施例二不同之处在于,步骤5E中将DCI format 0_1、DCI format 1_1与CSS和USS中DCI format 0_0、DCI format 1_0的DCI长度对齐。

上述步骤1-步骤5D的过程分别与实施例一的步骤1-步骤5D的过程都相同,因此,关于步骤1-步骤5D的具体描述可分别参考实施例二中关于各个步骤的相关描述,不再赘述。
步骤5E、对齐DCI format 0_1、DCI format 1_1与CSS和USS中DCI format 0_0、DCI format 1_0的DCI长度。
由于在步骤5E之前,已经对齐了DCI format 0_1、DCI format 1_1的DCI长度,以及对齐了USS和CSS中DCI format 0_0、DCI format 1_0的DCI长度,所以,在该步骤中,这4个DCI格式仅有2个DCI长度,只需要将这2个DCI长度对齐为一个DCI长度即可。例如,如表11所示,经过步骤5E最终得到的DCI format 0_1、DCI format 1_1的DCI长度由之前的size H变为size L3,经过步骤5E最终得到的USS和CSS的DCI format 0_0、DCI format 1_0的DCI长度由之前的size A变为size L3。
在一些实施例中,可以以DCI format 0_1和DCI format 1_1的DCI长度(例如,size H)与DCI format 0_0和DCI format 1_0的DCI长度(例如,size A)中DCI长度大的DCI长度作为基准,对其余DCI长度小的DCI执行补零操作,将两个DCI长度变为一个DCI长度。
若DCI format 0_0和DCI format 1_0的DCI长度(例如,size A)比DCI format 0_1和DCI format 1_1的DCI长度(例如,size H)小,那么对DCI format 0_0和DCI format 1_0执行相同的补零操作,在DCI format 0_0和DCI format 1_0后填充零作为padding,使得最终确定的DCI format 0_0和DCI format 1_0的DCI长度与DCI format 0_1和DCI format 1_1的DCI长度相同。在该情况中,表11中的size L3即为size H。
若DCI format 0_1和DCI format 1_1的DCI长度(例如,size H)比DCI format 0_0和DCI format 1_0的DCI长度(例如,size A)小,那么对DCI format 0_1和DCI format 1_1执行相同的补零操作,在DCI format 0_1和DCI format 1_1后填充零作为padding,使得最终确定的DCI format 0_0和DCI format 1_0的DCI长度与DCI format 0_3和DCI format 1_3的DCI长度相同。在该情况中,表11中的size L3即为size A。
应理解,上述以DCI format 0_1和DCI format 1_1的DCI长度(例如,size H)与DCI format 0_0和DCI format 1_0的DCI长度(例如,size A)中DCI长度大的DCI长度作为基准将两个DCI长度拉齐的方式仅为示意性说明,任何能够对齐上述4个DCI的DCI长度的方法都可行。例如,可以将DCI format 0_1和DCI format 1_1的DCI长度(例如,size H)与DCI format 0_0和DCI format 1_0的DCI长度(例如,size A)中任一个的DCI长度作为基准,对其余两个DCI执行相同的对齐操作(补零操作或截短操作),以将两个DCI长度对齐,将两个DCI长度变为一个DCI长度。
经过步骤5E后,再次减少了一个DCI长度,继续判断上述确定的DCI是否满足DCI长度预算,若经过上述步骤1-步骤5E得到的DCI长度的数量满足DCI长度预算,则将上述步骤1-步骤5E确定的DCI长度作为盲检过程中最终采用的DCI长度。

上述步骤1-步骤5D的过程分别与实施例一的步骤1-步骤5D的过程都相同,因此,关于步骤1-步骤5D的具体描述可分别参考实施例二中关于各个步骤的相关描述,不再赘述。
步骤5E、对齐DCI format 0_1、DCI format 1_1与DCI format 0_3、DCI format 1_3的DCI长度。
由于在步骤5E之前,已经对齐了DCI format 0_1、DCI format 1_1的DCI长度(例如,size H),以及对齐了DCI format 0_3、DCI format 1_3的DCI长度(例如,size G),所以,在该步骤中,这4个DCI格式仅有2个DCI长度,只需要将这2个DCI长度对齐为一个DCI长度即可。例如,如表12所示,经过步骤5E最终得到的DCI format 0_1、DCI format 1_1的DCI长度由之前的size H变为size L4,经过步骤5E最终得到的DCI format 0_03、DCI format 1_3的DCI长度由之前的size G变为size L4。
在一些实施例中,可以以DCI format 0_1和DCI format 1_1的DCI长度(例如,size H)与DCI format 0_3和DCI format 1_3的DCI长度(例如,size G)中DCI长度大的DCI长度作为基准,对其余DCI长度小的DCI执行补零操作,将两个DCI长度变为一个DCI长度。
若DCI format 0_1和DCI format 1_1的DCI长度(例如,size H)比DCI format 0_3和DCI format 1_3的DCI长度(例如,size G)小,那么对DCI format 0_1和DCI format 1_1执行相同的补零操作,在DCI format 0_1和DCI format 1_1后填充零作为padding,使得最终确定的DCI format 0_1和DCI format 1_1的DCI长度与DCI format 0_3和DCI format 1_3的DCI长度相同。在该情况中,表12中的size L4即为size G。
若DCI format 0_3和DCI format 1_3的DCI长度(例如,size G)比DCI format 0_1和DCI format 1_1的DCI长度(例如,size H)小,那么对DCI format 0_3和DCI format 1_3执行相同的补零操作,在DCI format 0_3和DCI format 1_3后填充零作为padding,使得最终确定的DCI format 0_3和DCI format 1_3的DCI长度与DCI format 0_1和DCI format 1_1的DCI长度相同。在该情况中,表12中的size L4即为size H。
应理解,上述以DCI format 0_1和DCI format 1_1的DCI长度(例如,size H)与DCI format 0_3和DCI format 1_3的DCI长度(例如,size G)中DCI长度大的DCI长度作为基准将两个DCI长度拉齐的方式仅为示意性说明,任何能够对齐上述4个DCI的DCI长度的方法都可行。例如,可以将DCI format 0_1和DCI format 1_1的DCI长度(例如,size H)与DCI format 0_3和DCI format 1_3的DCI长度(例如,size G)中任一个的DCI长度作为基准,对其余两个DCI执行相同的对齐操作(补零操作或截短操作),以将两个DCI长度对齐,将两个DCI长度变为一个DCI长度。
经过步骤5E后,再次减少了一个DCI长度,继续判断上述确定的DCI是否满足DCI长度预算,若经过上述步骤1-步骤5E得到的DCI长度的数量满足DCI长度预算,则将上述步骤1-步骤5E确定的DCI长度作为盲检过程中最终采用的DCI长度。
假设,经过步骤5E后,得到的DCI长度包括:size L4、size A、size K,若各个DCI长度都不相同,则DCI长度的数量为3,满足DCI长度预算,那么,size L4、size A、size K则为盲检过程中最终采用的DCI长度,终端设备分别采用size L4、size A、size K对DCI进行盲检,以获得网络设备发送的DCI。
应理解,本申请实施例对上述步骤5A-步骤5E的执行顺序不做任何限定,上述执行顺序仅为示意性说明。
本申请实施例提供的多载波调度的方法,在sDCI和mDCI共存场景下,通过将同系列(例如,DCI format x_0、DCI format x_1、DCI format x_2或DCI format x_3)的DCI长度对齐后,以及,将DCI format x_3与DCI format x_1的DCI长度对齐,使得DCI长度的数量控制在3,满足DCI长度预算,减少了盲检复杂度,提高了系统传输性能。并且,由于DCI format x_3与DCI format x_1的DCI长度相差不大,将DCI format x_3与DCI format x_1的DCI长度对齐的过程中,在需要以DCI format x_3对应的DCI长度和DCI format x_1对应的DCI长度中的一个DCI长度作为基准,对另一系列DCI对应的DCI长度执行补零操作的情况下,不会增加较多的比特数,可以避免DCI长度对齐过程中可能增加的大量开销的问题。

步骤5E、对齐DCI format 0_2、DCI format 1_2与DCI format 0_3、DCI format 1_3的DCI长度。
由于在步骤5E之前,已经对齐了DCI format 0_2、DCI format 1_2的DCI长度(例如,size K),以及对齐了DCI format 0_3、DCI format 1_3的DCI长度(例如,size G),所以,在该步骤中,这4个DCI格式仅有2个DCI长度,只需要将这2个DCI长度对齐为一个DCI长度即可。例如,如表13所示,经过步骤5E最终得到的DCI format 0_2、DCI format 1_2的DCI长度由之前的size K变为size L5,经过步骤5E最终得到的DCI format 0_3、DCI format 1_3的DCI长度由之前的size G变为size L5。
在一些实施例中,可以以DCI format 0_2和DCI format 1_2的DCI长度(例如,size K)与DCI format 0_3和DCI format 1_3的DCI长度(例如,size G)中DCI长度大的DCI长度作为基准,对其余DCI长度小的DCI执行补零操作,将两个DCI长度变为一个DCI长度。
若DCI format 0_2和DCI format 1_2的DCI长度(例如,size K)比DCI format 0_3 和DCI format 1_3的DCI长度(例如,size G)小,那么对DCI format 0_2和DCI format 1_2执行相同的补零操作,在DCI format 0_2和DCI format 1_2后填充零作为padding,使得最终确定的DCI format 0_2和DCI format 1_2的DCI长度与DCI format 0_3和DCI format 1_3的DCI长度相同。在该情况中,表13中的size L5即为size G。
若DCI format 0_3和DCI format 1_3的DCI长度(例如,size G)比DCI format 0_2和DCI format 1_2的DCI长度(例如,size K)小,那么对DCI format 0_3和DCI format 1_3执行相同的补零操作,在DCI format 0_3和DCI format 1_3后填充零作为padding,使得最终确定的DCI format 0_3和DCI format 1_3的DCI长度与DCI format 0_2和DCI format 1_2的DCI长度相同。在该情况中,表12中的size L5即为size K。
应理解,上述以DCI format 0_2和DCI format 1_2的DCI长度(例如,size K)与DCI format 0_3和DCI format 1_3的DCI长度(例如,size G)中DCI长度大的DCI长度作为基准将两个DCI长度拉齐的方式仅为示意性说明,任何能够对齐上述4个DCI的DCI长度的方法都可行。例如,可以将DCI format 0_2和DCI format 1_2的DCI长度(例如,size K)与DCI format 0_3和DCI format 1_3的DCI长度(例如,size G)中任一个的DCI长度作为基准,对其余两个DCI执行相同的对齐操作(补零操作或截短操作),以将两个DCI长度对齐,将两个DCI长度变为一个DCI长度。
经过步骤5E后,再次减少了一个DCI长度,继续判断上述确定的DCI是否满足DCI长度预算,若经过上述步骤1-步骤5E得到的DCI长度的数量满足DCI长度预算,则将上述步骤1-步骤5E确定的DCI长度作为盲检过程中最终采用的DCI长度。
假设,经过步骤5E后,得到的DCI长度包括:size L5、size A、size H,若各个DCI长度都不相同,则DCI长度的数量为3,满足DCI长度预算,那么,size L5、size A、size H则为盲检过程中最终采用的DCI长度,终端设备分别采用size L5、size A、size H对DCI进行盲检,以获得网络设备发送的DCI。

步骤5E、对齐DCI format 0_2、DCI format 1_2与DCI format 0_31、DCI format 1_1的DCI长度。
由于在步骤5E之前,已经对齐了DCI format 0_2、DCI format 1_2的DCI长度(例如,size K),以及对齐了DCI format 0_1、DCI format 1_1的DCI长度(例如,size H),所以,在该步骤中,这4个DCI格式仅有2个DCI长度,只需要将这2个DCI长度对齐为一个DCI长度即可。例如,如表14所示,经过步骤5E最终得到的DCI format 0_2、DCI format 1_2的DCI长度由之前的size K变为size L6,经过步骤5E最终得到的DCI format 0_1、DCI format 1_1的DCI长度由之前的size H变为size L6。
在一些实施例中,可以以DCI format 0_2和DCI format 1_2的DCI长度(例如,size K)与DCI format 0_1和DCI format 1_1的DCI长度(例如,size H)中DCI长度大的DCI长度作为基准,对其余DCI长度小的DCI执行补零操作,将两个DCI长度变为一个DCI长度。
若DCI format 0_2和DCI format 1_2的DCI长度(例如,size K)比DCI format 0_1和DCI format 1_1的DCI长度(例如,size H)小,那么对DCI format 0_2和DCI format 1_2执行相同的补零操作,在DCI format 0_2和DCI format 1_2后填充零作为padding,使得最终确定的DCI format 0_2和DCI format 1_2的DCI长度与DCI format 0_1和DCI format 1_1的DCI长度相同。在该情况中,表14中的size L6即为size H。
若DCI format 0_1和DCI format 1_1的DCI长度(例如,size H)比DCI format 0_2和DCI format 1_2的DCI长度(例如,size K)小,那么对DCI format 0_1和DCI format 1_1执行相同的补零操作,在DCI format 0_1和DCI format 1_1后填充零作为padding,使得最终确定的DCI format 0_1和DCI format 1_1的DCI长度与DCI format 0_2和DCI format 1_2的DCI长度相同。在该情况中,表14中的size L6即为size K。
应理解,上述以DCI format 0_2和DCI format 1_2的DCI长度(例如,size K)与DCI format 0_1和DCI format 1_1的DCI长度(例如,size H)中DCI长度大的DCI长度作为基准将两个DCI长度拉齐的方式仅为示意性说明,任何能够对齐上述4个DCI的DCI长度的方法都可行。例如,可以将DCI format 0_2和DCI format 1_2的DCI长度(例如,size K)与DCI format 0_1和DCI format 1_1的DCI长度(例如,size H)中任一个的DCI长度作为基准,对其余两个DCI执行相同的对齐操作(补零操作或截短操作),以将两个DCI长度对齐,将两个DCI长度变为一个DCI长度。
经过步骤5E后,再次减少了一个DCI长度,继续判断上述确定的DCI是否满足DCI长度预算,若经过上述步骤1-步骤5E得到的DCI长度的数量满足DCI长度预算,则将上述步骤1-步骤5E确定的DCI长度作为盲检过程中最终采用的DCI长度。
假设,经过步骤5E后,得到的DCI长度包括:size L6、size A、size G,若各个DCI长度都不相同,则DCI长度的数量为3,满足DCI长度预算,那么,size L6、size A、size G则为盲检过程中最终采用的DCI长度,终端设备分别采用size L6、size A、size G对DCI进行盲检,以获得网络设备发送的DCI。
应理解,本申请实施例对上述步骤5A-步骤5E的执行顺序不做任何限定,上述执行顺序仅为示意性说明。
本申请实施例提供的多载波调度的方法,在sDCI和mDCI共存场景下,通过将同系 列(例如,DCI format x_0、DCI format x_1、DCI format x_2或DCI format x_3)的DCI长度对齐后,以及,将DCI format x_2与DCI format x_1的DCI长度对齐,使得DCI长度的数量控制在3,满足DCI长度预算,减少了盲检复杂度,提高了系统传输性能。
针对上述实施例,当不同格式的DCI的DCI长度对齐时,需要针对不同的DCI格式进行区分。例如,需要区分DCI format 0_3和DCI format 1_3,可以在DCI中携带1比特的指示域,1表示下行调度的DCI,即表示DCI format 1_3,0表示上行调度的DCI,即表示DCI format 0_3。再例如,需要区分DCI format x_3和DCI format x_1,可以在DCI中携带1比特的指示域,1表示DCI format x_3,0表示DCI format x_1,或使用特殊的RNTI(例如,C-M-RNTI)加扰DCI formatx_3。
实施例八
如前所述,在确定DCI长度是否满足DCI长度预算时,以被DCI调度的载波对应的小区的DCI长度预算进行确定。多种格式的DCI可调度同一个小区对应的载波,对于该小区而言,终端设备和网络设备需要确定该多种格式的DCI的DCI长度以及判断确定的DCI长度是否满足该小区的DCI长度预算,在满足DCI长度预算的情况下,对齐操作结束,在不满足DCI长度预算的情况下,继续执行对齐操作,重新确定DCI长度。考虑到DCI长度预算中经过C-RNTI加扰的不同的DCI长度的数量不超过3的要求,本申请实施例的DCI长度预算不超过3,即,DCI长度预算包括3个不同长度的DCI长度。
如前所述,NR目前主要支持的sDCI主要分为3种系列的DCI格式,分别是:DCI format x_0、DCI format x_1、DCI format x_2,不同系列的DCI格式的x的取值不同。示例性地,在DCI format x_0系列中,x的取值可以为0或1,对应地,包括的DCI格式为:DCI format 0_0、DCI format 1_0;在DCI format x_1系列中,x的取值可以为0或1,对应地,包括的DCI格式为:DCI format 0_1、DCI format 1_1;在DCI format x_2系列中,x的取值可以为0或1,对应地,包括的DCI格式为:DCI format 0_2、DCI format 1_2。当然,上述列举的各个系列的DCI格式仅为示意性说明,每个系列可以包括更多的DCI格式,本申请实施例不做任何限定。
在sDCI的上述3种系列的DCI格式中,DCI format x_0只能调度主小区对应的载波,DCI format x_1和DCI format x_2可以调度主小区和辅小区对应的载波。为了满足DCI长度预算不超过3的需求,本申请实施例规定,对于主小区,DCI format x_0的DCI长度、DCI format x_1的DCI长度、DCI format x_2的DCI长度属于主小区的DCI长度预算,一个系列的DCI格式对应一个DCI长度,3个系列的DCI格式分别对应3个DCI长度,这样,在3个DCI长度不同的情况下,主小区的DCI长度最多为3个,刚好满足DCI长度预算的最大值。对于辅小区,由于DCI format x_0不能调度辅小区对应的载波,所以,DCI format x_1、DCI format x_2的DCI的DCI长度可以属于辅小区的DCI长度预算,同理,一个系列的DCI格式对应一个DCI长度,2个系列的DCI格式分别对应2个DCI长度,这样,在3个DCI长度不同的情况下,辅小区的DCI长度最多为2个,辅小区的DCI长度预算还剩余1个DCI长度。应理解,上述一个系列的DCI格式对应的一个DCI长度表示的是最终满足DCI长度预算的DCI长度,即为盲检过程中最终采用的DCI长度,该DCI长度可以是将该系列的多个DCI格式的原始比特长度对齐后得到的DCI长度,在该系列的多个DCI格式的原始比特长度相同的情况下,该DCI长度也可以是未对齐前的原始比 特长度。
由于mDCI调度多个载波,意味着mDCI的DCI长度可以属于任一个被调度的载波对应的小区的DCI长度预算。在mDCI和sDCI共存的场景下,若mDCI分别调度主小区和辅小区对应的载波,由于主小区的DCI长度预算已经被sDCI占满,即,主小区的DCI长度预算最多已经有3个DCI长度,满足了DCI长度预算的最大限制,而辅小区仅被DCI format x_1的DCI长度和DCI format x_2的DCI长度占据了2个DCI长度预算,即辅小区的DCI长度最多只有2个,辅小区还剩余1个DCI长度预算,所以,将mDCI的DCI长度划分至辅小区的DCI长度预算,这样,辅小区最多有3个DCI长度,刚好满足DCI长度预算的最大值。若mDCI分别调度两个辅小区对应的载波,同理,由于DCI format x_1的DCI长度和DCI format x_2的DCI长度仅占据了辅小区的2个DCI长度预算,所以,将mDCI的DCI长度划分至任一个辅小区的DCI长度预算,这样,辅小区最多有3个DCI长度,满足DCI长度预算的最大值。应理解,mDCI的DCI长度是最终满足DCI长度预算的DCI长度,即盲检过程中最终采用的DCI长度,该DCI长度可以是将mDCI的多个DCI格式的原始比特长度对齐后得到的DCI长度,在mDCI的多个DCI格式的原始比特长度相同的情况下,该DCI长度也可以是未对齐前的原始比特长度。
在一些实施例中,mDCI的DCI格式可以是上文的DCI format x_3系列的DCI格式,示例性地,具体可以包括用于调度PUSCH的DCI format 0_3和用于调度PDSCH的DCI format 1_3。综上,在sDCI和mDCI共存场景下,基于DCI长度预算确定DCI长度时,本申请实施例提出,将mDCI的DCI长度划分至辅小区的DCI长度预算,将sDCI中DCI format x_0的DCI长度划分至主小区的DCI长度预算,将DCI format x_1、DCI format x_2的DCI长度划分至主小区和辅小区的DCI长度预算,换句话说,mDCI的DCI长度属于辅小区的DCI长度预算,sDCI中DCI format x_0的DCI长度属于主小区的DCI长度预算,DCI format x_1、DCI format x_2的DCI长度属于主小区和辅小区的DCI长度预算。这样,主小区的3个DCI长度可对应sDCI的DCI format x_0的DCI长度、DCI format x_1的DCI长度、DCI format x_2的DCI长度,辅小区的3个DCI长度可对应sDCI的DCI format x_1的DCI长度、DCI format x_2的DCI长度以及mDCI的DCI长度。
基于上述定义的DCI格式的DCI长度与小区的关系,对网络设备配置的多种格式的DCI,根据每个DCI调度的载波对应的小区的DCI长度预算,确定盲检过程中最终采用的DCI长度。
这里需要说明的是,在该实施例中,每个系列的DCI格式对应一个DCI长度,在确定每个系列的DCI格式对应的DCI长度时,可以采用任意可能的方式得到该系列的DCI格式对应的DCI长度,示例性地,确定每个系列的DCI格式对应的DCI长度的方式可参考上文实施例一至实施例七的方式。下面,分别以主小区的3个DCI长度和辅小区的3个DCI长度进行举例说明。
主小区的3个DCI长度对应sDCI的DCI format x_0的DCI长度、DCI format x_1的DCI长度、DCI format x_2的DCI长度。假设,网络设备配置了CSS中的DCI format 0_0、CSS中的DCI format 1_0、USS中的DCI format 0_0、USS中的DCI format 1_0、USS中的DCI format 0_1、USS中的DCI format 1_1、USS中的DCI format 0_2、USS中的DCI format 1_2,该8个DCI都调度主小区对应的载波。确定CSS中的DCI format 0_0、CSS中的DCI  format 1_0、USS中的DCI format 0_0、USS中的DCI format 1_0对应的DCI长度的方式可参考实施例二中的步骤1、步骤2和步骤5A,当然,在基于步骤1和步骤2得到的A与B相同的情况下,不需要执行步骤5A。确定USS中的DCI format 0_1、USS中的DCI format 1_1对应的DCI长度的方式可参考实施例二中的步骤3A和步骤5C,当然,在基于步骤3A得到的C与D相同的情况下,不需要执行步骤5C。确定USS中的DCI format 0_2、USS中的DCI format 1_2对应的DCI长度的方式可参考实施例二中的步骤3B和步骤5B,当然,在基于步骤3B得到的M与N相同的情况下,不需要执行步骤5B。
辅小区的3个DCI长度可对应sDCI的DCI format x_1的DCI长度、DCI format x_2的DCI长度以及mDCI的DCI长度,假设mDCI的DCI格式包括DCI format 0_3和DCI format 1_3。假设,网络设备配置了USS中的DCI format 0_1、USS中的DCI format 1_1、USS中的DCI format 0_2、USS中的DCI format 1_2、USS中的DCI format 0_3、USS中的DCI format 1_3,该6个DCI都调度同一个辅小区对应的载波,此外,DCI format 0_3调度的其余的载波可以是主小区或另一个辅小区的载波,DCI format 1_3调度的其余的载波也可以是主小区或另一个辅小区的载波。确定USS中的DCI format 0_1、USS中的DCI format 1_1对应的DCI长度的方式可参考实施例二中的步骤3A和步骤5C,当然,在基于步骤3A得到的C与D相同的情况下,不需要执行步骤5C。确定USS中的DCI format 0_2、USS中的DCI format 1_2对应的DCI长度的方式可参考实施例二中的步骤3B和步骤5B,当然,在基于步骤3B得到的M与N相同的情况下,不需要执行步骤5B。确定USS中的DCI format 0_3、USS中的DCI format 1_3对应的DCI长度的方式可参考实施例二中的步骤3C和步骤5D,当然,在基于步骤3C得到的E与F相同的情况下,不需要执行步骤5D。
本申请实施例的mDCI调度多个载波可以分为以下4种情况,下面,分情况详细介绍DCI格式的DCI长度与小区的关系。
以一个mDCI调度两个载波为例,图11是本申请实施例提供的mDCI调度多个载波的示意图。
情况A
在图11的(a)中,mDCI调度主小区(Pcell)对应的载波1和辅小区1(Scell1)对应的载波2,mDCI承载于主小区对应的载波1上。基于上述定义的主小区和辅小区对应的DCI格式的DCI长度,由于mDCI调度了辅小区1,所以,mDCI的DCI长度属于辅小区1的DCI长度预算,对于辅小区1,在确定DCI长度时,将mDCI的DCI长度按照辅小区1的DCI长度预算进行确定。对于主小区,仅需要将除了mDCI以外的其余DCI格式的DCI长度按照主小区的DCI长度预算进行确定,不需要考虑mDCI的DCI长度。此外,在该情况中,mDCI的DCI长度也可以认为是被调度载波对应的小区的DCI长度预算。
情况B
在图11中的(b)中,mDCI调度主小区(Pcell)对应的载波1和辅小区1(Scell1)对应的载波2,mDCI承载于辅小区1对应的载波2上。基于上述定义的主小区和辅小区对应的DCI格式的DCI长度,由于mDCI调度了辅小区1,所以,mDCI的DCI长度属于辅小区1的DCI长度预算,对于辅小区1,在确定DCI长度时,将mDCI的DCI长度按照辅小区1的DCI长度预算进行确定。对于主小区,仅需要将除了mDCI以外的其余DCI格式的DCI长度按照主小区的DCI长度预算进行确定,不需要考虑mDCI的DCI长度。 此外,在该情况中,mDCI的DCI长度也可以认为是调度载波对应的小区的DCI长度预算。
情况C
在图11中的(c)中,mDCI调度辅小区1(Scell1)对应的载波2和辅小区2(Scell2)对应的载波3,mDCI承载于主小区(Psell)对应的载波1上。基于上述定义的主小区和辅小区对应的DCI格式的DCI长度,由于mDCI调度了辅小区1和辅小区2,所以,mDCI的DCI长度属于辅小区1(或辅小区2)的DCI长度预算,在确定DCI长度时,将mDCI的DCI长度按照辅小区1(或辅小区2)的DCI长度预算进行计算,对于主小区,仅需要将除了mDCI以外的其余DCI格式的DCI长度按照主小区的DCI长度预算进行确定,不需要考虑mDCI的DCI长度。此外,在该情况中,mDCI的DCI长度也可以认为是被调度载波对应的小区的DCI长度预算。
情况D
在图11中的(d)中,mDCI调度辅小区1(Scell1)对应的载波2和辅小区2(Scell2)对应的载波3,mDCI承载于辅小区1对应的载波2上。基于上述定义的主小区和辅小区对应的DCI格式的DCI长度,由于mDCI调度了辅小区1和辅小区2,所以,mDCI的DCI长度属于辅小区1(或辅小区2)的DCI长度预算,在确定DCI长度时,将mDCI的DCI长度按照辅小区1或辅小区2的DCI长度预算进行确定,对于主小区,仅需要将除了mDCI以外的其余DCI格式的DCI长度按照主小区的DCI长度预算进行确定,不需要考虑mDCI的DCI长度。此外,在该情况中,若mDCI的DCI长度属于辅小区1的DCI长度预算,那么,mDCI的DCI长度也可以认为是调度载波对应的小区的DCI长度预算,若mDCI的DCI长度属于辅小区2的DCI长度预算,那么,mDCI的DCI长度也可以认为是被调度载波对应的小区的DCI长度预算。
第三方面,在mDCI和sDCI不共存的场景下,mDCI对应的调度模式和sDCI对应的调度模式之间的切换。
如前所述,在mDCI和sDCI不共存的场景中,终端设备不会在同一个时间单元内盲检sDCI和mDCI。
为了便于描述,将通过sDCI调度一个载波的调度模式称为单载波调度模式,将通过mDCI调度多个载波的调度模式称为多载波调度模式。以下是本申请实施例提供的指示调度模式的示例性的5种方式,分别对每种方式做说明。
方式1、通过高层信令显性指示调度模式
在该方式中,高层信令中可以配置有一个域,该域上承载的调度模式信息显性地指示调度模式为单载波调度模式或多载波调度模式。
在一些实施例中,若网络设备发送的高层信令的调度模式信息中比特的取值为第一数值,则指示调度模式为多载波调度模式,终端设备只盲检(或监听)多载波调度模式对应的mDCI,若网络设备发送的高层信令的调度模式信息中比特的取值为第二数值,则指示调度模式为单载波调度模式,终端设备只盲检单载波调度模式对应的sDCI。示例性地,第一数值为1以及第二数值为0,或,第一数值为0以及第二数值为1。
示例性地,该高层信令可以为RRC信令,MAC CE信令。
方式2、预定义调度模式
在该方式中,可以定义一个预定义的规则,该规则为:终端设备不期望同时盲检单载 波调度模式对应的sDCI和多载波调度模式对应的mDCI,或,终端设备不期望网络设备同时配置单载波调度模式对应的sDCI和多载波调度模式对应的mDCI。
实现中,网络设备配置单载波调度模式和多载波调度模式中任一个调度模式对应的DCI,终端设备盲检网络设备该任一种调度模式对应的DCI。
方式3、通过高层信令隐性指示调度模式
在该方式中,可以根据mDCI的DCI格式,通过高层信令隐性指示调度模式。下面示出的两个实施例适用于mDCI的第一种调度方式,即,一个mDCI通过调度多个数据信道调度对应的多个载波,一个载波用于承载一个数据信道。
示例性地,该高层信令可以为RRC信令。
mDCI的第一种DCI格式
mDCI的第一种DCI格式可以是上文第一方面描述的第一种DCI格式。在这种DCI格式中,mDCI包括两类域,第一类域包括至少一个共享域,第二类域包括至少一个独立域,关于共享域和独立域的具体描述可参考上文的相关描述,不再赘述。
在一些实施例中,高层信令中配置有DCI的域信息,该域信息用于指示DCI中的共享域和/或独立域,终端设备基于该域信息,以确定DCI的调度模式。
在一示例中,域信息用于指示DCI中的共享域和独立域。若终端设备基于该域信息可以确定DCI中的一部分域是共享域以及另一部分域是独立域,则表示DCI中存在共享域和独立域,则表示该DCI是mDCI,调度模式是多载波调度模式。
在另一示例中,域信息用于指示DCI的共享域。若域信息指示的共享域是DCI中的一部分域,意味着另一部分域是独立域,则表示DCI中存在共享域和独立域,则表示该DCI是mDCI,调度模式是多载波调度模式。若域信息指示的共享域是DCI中的所有域,由于该方式定义的mDCI包括共享域和独立域,所以,若域信息指示DCI中所有域是共享域,则默认该DCI是sDCI,调度模式是单载波调度模式。
在另一示例中,域信息用于指示DCI的独立域。若域信息指示的独立域是DCI中的一部分域,意味着另一部分域是共享域,表示DCI中存在共享域和独立域,则表示该DCI是mDCI,调度模式是多载波调度模式。若域信息指示的独立域是DCI中的所有域,则该DCI是sDCI,调度模式是单载波调度模式。
mDCI的第二种DCI格式
mDCI的第二种DCI格式可以是上文第一方面描述的第二种DCI格式。mDCI中预配置有多组域,每组域对应一个数据信道(或载波),每组域包括多个域,每组域相当于一个sDCI中的所有域,用于实现调度一个数据信道的功能。关于这种DCI格式的具体描述可参考上文的相关描述,不再赘述。
基于上述第一种DCI格式,在一些实施例中,网络设备发送的高层信令中可以配置有DCI的域信息,该域信息用于确定DCI中可用的域,终端设备基于该域信息,确定DCI的调度模式。
在一示例中,域信息用于指示DCI中的候选域中可用的域。在该实施例中,mDCI中的一组域是预定义的可用的域,多组域中除预定义的这组域以外的域是候选域,通过高层信令的域信息指示该候选域中可用的域。若域信息指示DCI中的候选域中存在至少一组域是可用的域,则可以确定该DCI中预定义的一组域和通过该域信息确定的至少一组域是可 用的域,由于一组域用于实现调度一个数据信道的功能,所以,意味着该DCI是mDCI,调度模式是多载波调度模式。若域信息指示DCI中的候选域中的可用的域为零,则表示不存在是可用的域,可以确定该DCI中只有预定义的一组域是可用的域,所以,意味着该DCI是sDCI,调度模式是单载波调度模式。例如,mDCI中预配置有48个域,分为2组域,预定义其中的第1组域是可用的域,第2组域是候选域,那么,若基于域信息确定候选域是可用的域,则表示该DCI是mDCI,调度模式是多载波调度模式,若基于域信息确定候选域是不可用的域,则表示该DCI是sDCI,调度模式是单载波调度模式。
在另一示例中,域信息用于指示DCI中可用的域。在该实施例中,mDCI中可用的域都是通过高层信令的域信息指示。若基于高层信令的域信息确定的DCI中可用的域是mDCI预配置的多组域,则表示该DCI是mDCI,调度模式是多载波调度模式。若基于高层信令的域信息确定的DCI中可用的域是mDCI预配置的多组域中的一组域,意味着有不可用的域,则表示该DCI是sDCI,调度模式是单载波调度模式。例如,mDCI中预配置有48个域,分为2组域,每组域包括24个域,若基于域信息确定的DCI中可用的域为48个域,则可以确定该DCI是mDCI,调度模式是多载波调度模式,若基于域信息确定的DCI中可用的域的数量为24,意味着有24个域可用,还有24个域不可用,则可以确定该DCI是sDCI,调度模式是单载波调度模式。
方式4、通过DCI指示调度模式
在该方式中,通过DCI指示下一个DCI的调度模式,该DCI可以是sDCI或mDCI,sDCI可以是上文描述的任一种格式的DCI。
在一些实施例中,DCI中配置有一个域,该域上承载的调度模式信息可用于指示调度模式为单载波调度模式或多载波调度模式。关于该调度模式信息的具体描述可参考方式1中高层信令中的调度模式信息,不再赘述。
在一示例中,该用于承载调度模式信息的域可以是DCI中新增加的域。
在另一示例中,该用于承载调度模式信息的域可以是DCI中本身已有的域,或者说,复用DCI中本身已有的域来承载调度模式信息,例如,DCI中本身已有的域可以是BWP域或其他特殊域。该示例中的DCI可以是sDCI。
在另一些实施例中,可以采用加扰DCI的RNTI来指示调度模式是多载波调度模式或单载波调度模式。示例性地,采用第一RNTI指示单载波调度模式,采用第二RNTI指示多载波调度模式,例如,第一RNTI为C-RNTI,第二RNTI为C-M-RNTI。
图12是本申请实施例提供的多载波调度的方法100的示意性结构图。该方法100可适用于图1所示的通信系统中,由网络设备和终端设备执行。
在S110中,网络设备发送第一配置信息,该第一配置信息用于配置第一下行控制信息DCI和第二DCI,该第一DCI用于调度M个载波,该第二DCI用于调度一个载波,M为大于1的整数,该第一DCI的第一监听比特长度和该第二DCI的第一监听比特长度不同。对应地,终端设备接收该第一配置信息。
在S120中,网络设备根据第二监听比特长度,发送该第一DCI和该第二DCI中的至少一个,其中,该第二监听比特长度是根据该第一DCI的第一监听比特长度和该第二DCI的第一监听比特长度确定的。
在S130中,终端设备根据第二监听比特长度,监听该第一DCI和该第二DCI,其中, 该第二监听比特长度是根据该第一DCI的第一监听比特长度和该第二DCI的第一监听比特长度确定的。
具体地,网络设备可以通过第一配置信息为终端设备配置两个DCI,第一DCI用于调度M个载波,是一个多载波调度的DCI(即上文定义的mDCI中的一例),第二DCI用于调度一个载波,是一个单载波调度的DCI(即上文定义的sDCI中的一例)。网络设备确定第一DCI的第一监听比特长度和第二DCI的第一监听比特长度,在两个DCI的第一监听比特长度不同时,为了减少盲检复杂度,网络设备根据第一DCI的第一监听比特长度和第二DCI的第一监听比特长度确定最终的一个监听比特长度,即第二监听比特长度,根据第二监听比特长度向终端设备发送第一DCI和第二DCI的至少一个。为了与网络设备的理解一致,终端设备与网络设备执行相同的步骤,终端设备确定第一DCI的第一监听比特长度和第二DCI的第一监听比特长度,在两个DCI的第一监听比特长度不同时,根据第一DCI的第一监听比特长度和第二DCI的第一监听比特长度确定最终的第二监听比特长度,根据该第二监听比特长度监听第一DCI和第二DCI,以获得网络设备发送的DCI。
在上述基于第一配置信息配置的两个DCI中,每个DCI都具有各自的原始比特长度,网络设备可以通过第二配置信息配置每个DCI的原始比特长度,终端设备或网络设备可以根据第二配置信息确定每个DCI的第一监听比特长度,其中,每个DCI的第一监听比特长度可以是DCI的原始比特长度,也可以是对原始比特长度执行对齐后的比特长度。
对于第一DCI而言,在一示例中,第一DCI的第一监听比特长度可以是第一DCI的原始比特长度。在该示例中,网络设备或终端设备根据第二配置信息确定第一DCI的第一监听比特长度,可以理解为,根据第二配置信息直接确定第一DCI的第一监听比特长度,不需要第一DCI的原始比特长度执行对齐操作,或者,可以理解为,根据第二配置信息确定第一DCI的原始比特长度,将第一DCI的原始比特长度作为第一DCI的第一监听比特长度。
在另一示例中,第一DCI的第一监听比特长度可以对第一DCI的原始比特长度执行对齐操作后得到的比特长度(具体参考下文描述)。在该示例中,网络设备或终端设备根据第二配置信息确定第一DCI的第一监听比特长度,可以理解为,根据第二配置信息确定第一DCI的原始比特长度,根据第一DCI的原始比特长度确定第一DCI的第一监听比特长度。实现过程中,可以将第一DCI与其他DCI的比特长度对齐,以其他DCI的比特长度作为基准,对第一DCI的原始比特长度执行对齐操作,得到对齐后的比特长度。
对于第二DCI而言,在一示例中,第二DCI的第一监听比特长度可以是第二DCI的原始比特长度,在该示例中,网络设备或终端设备根据第二配置信息确定第二DCI的第一监听比特长度,可以理解为,根据第二配置信息直接确定第二DCI的第一监听比特长度,不需要对第二DCI的原始比特长度执行对齐操作,或者,可以理解为,根据第二配置信息确定第二DCI的原始比特长度,将第二DCI的原始比特长度作为第二DCI的第一监听比特长度。
在另一示例中,第二DCI的第一监听比特长度可以对第二DCI的原始比特长度执行对齐操作后得到的比特长度(具体参考下文描述)。在该示例中,网络设备或终端设备根据第二配置信息确定第二DCI的第一监听比特长度,可以理解为,根据第二配置信息确定第二DCI的原始比特长度,根据第二DCI的原始比特长度确定第二DCI的第一监听比特 长度。实现过程中,可以将第二DCI与其他DCI的比特长度对齐,以其他DCI的比特长度作为基准,对第二DCI的原始比特长度执行对齐操作,得到对齐后的比特长度。
在根据第二配置信息确定第一DCI的第一监听比特长度和第二DCI的第一监听比特长度后,网络设备或终端设备根据第一DCI的第一监听比特长度和第二DCI的第一监听比特长度确定第二监听比特长度。在这个过程中,网络设备或终端设备可以将这两个DCI的第一监听比特长度对齐,以得到第二监听比特长度。示例性地,第二监听比特长度可以与第一DCI的第一监听比特长度和第二DCI的第一监听比特长度中的任一个相同,本申请实施例不做限定,具体以实现过程为准。
在一些实施例中,可以以第一DCI的第一监听比特长度和第二DCI的第一监听比特长度中比特长度长的比特长度作为基准,对另一个DCI的比特长度执行对齐操作,得到第二监听比特长度,其中,这里的对齐操作是补零操作。
在一示例性中,若第一DCI的第一监听比特长度比第二DCI的第一监听比特长度长,则以第一DCI的第一监听比特长度作为基准,对第二DCI的第一监听比特长度执行对齐操作,得到第二监听比特长度。在该示例中,第二监听比特长度与第一DCI的第一监听比特长度相同。
在另一示例中,若第二DCI的第一监听比特长度比第一DCI的第一监听比特长度长,则以第二DCI的第一监听比特长度作为基准,对第一DCI的第一监听比特长度执行对齐操作,得到第二监听比特长度。在该示例中,第二监听比特长度与第二DCI的第一监听比特长度相同。
在另一些实施例中,可以以第一DCI的第一监听比特长度和第二DCI的第一监听比特长度中比特长度短的比特长度作为基准,对另一个DCI的比特长度执行对齐操作,得到第二监听比特长度,其中,这里的对齐操作是截短操作。
在一示例性中,若第一DCI的第一监听比特长度比第二DCI的第一监听比特长度短,则以第一DCI的第一监听比特长度作为基准,对第二DCI的第一监听比特长度执行对齐操作,得到第二监听比特长度。在该示例中,第二监听比特长度与第一DCI的第一监听比特长度相同。
在另一示例中,若第二DCI的第一监听比特长度比第一DCI的第一监听比特长度短,则以第二DCI的第一监听比特长度作为基准,对第一DCI的第一监听比特长度执行对齐操作,得到第二监听比特长度。在该示例中,第二监听比特长度与第二DCI的第一监听比特长度相同。
应理解,由于终端设备盲检过程中最终采用的是第二监听比特长度,对于第二监听比特长度而言,第一DCI的第一监听比特长度和第二DCI的第一监听比特长度都可以理解为一种候选的监听比特长度,基于两个DCI的候选的监听比特长度可以得到最终的第二监听比特长度。
在本申请实施例中,DCI的“原始比特长度”表示的是网络设备通过第二配置信息配置的DCI中各个域所占比特长度的大小,仅根据上述第二配置信息的配置就可以确定DCI的原始比特长度,即,DCI的原始比特长度可以仅根据第二配置信息得到,不包含经过其他操作(例如,对齐操作)后得到的处理后的比特长度,或者说,DCI的原始比特长度是在对DCI进行对齐操作之前的比特长度。
对齐操作包括补零操作或截短操作,补零操作表示对DCI增加至少一个比特零以增加DCI长度的操作,截短操作表示将一个DCI截短减少DCI长度的操作,具体地,截短操作可以是删除相应字段的部分信息比特的操作,也可以是删除相应字段的全部信息比特操作。
应理解,本申请实施例采用上述各个比特长度(例如,原始比特长度,各种监听比特长度)的名称仅仅是为了便于描述,本申请实施例对DCI进行对齐操作前后的长度的名称并不作限定。
在该实施例中,第一DCI可以为上文的mDCI的一例,例如,第一DCI的格式为可以为上文的DCI format 0_3或DCI format 1_3。第二DCI可以为上文的sDCI的一例,例如,第二DCI的格式可以为以下任一个:CSS中的DCI format0_0、CSS中的DCI format 1_0、USS中的DCI format0_0、USS中的DCI format 1_0、USS中的DCI format 0_1、USS中的DCI format 1_1、USS中的DCI format 0_2、USS中的DCI format 1_2。
在上述第一DCI调度的M个载波和第二DCI调度的一个载波中,该M个载波可以包括该第二DCI调度的一个载波,也可以不包括该第二DCI调度的一个载波。
对于一个小区调度多个载波的情况,第一DCI调度的M个载波和第二DCI调度的一个载波属于同一个小区对应的载波。在一示例中,该M个载波可以包括第二DCI调度的一个载波。例如,小区1对应3个载波,载波1、载波2和载波3,M=2,第一DCI调度的2个载波是小区1对应的载波1和载波2,第二DCI调度的载波是载波1。在另一示例中,该M个载波也可以不包括该第二DCI调度的一个载波。例如,小区1对应3个载波,载波1、载波2和载波3,M=2,第一DCI调度的2个载波是小区1对应的载波1和载波2,第二DCI调度的载波是载波3。
对于一个小区调度一个载波的情况,该M个载波属于至少两个小区对应的载波,第二DCI调度的一个载波是一个小区对应的载波,该M个载波中的一个载波和第二DCI调度的一个载波是同一个小区对应的载波,这种情况中,该M个载波包括该第二DCI调度的载波。例如,M=2,第一DCI调度载波1和载波2,载波1是小区1对应的载波,载波2是小区2对应的载波,第二DCI调度的载波可以是载波1或载波2。
对于第二DCI调度的M个载波包括第二DCI调度的一个载波的情况,示例性地,该M个载波包括第一载波,该第二DCI用于调度该第一载波。
可选地,上述第一配置信息还用于配置第一DCI的搜索空间和第二DCI的搜索空间。第一DCI的搜索空间和第二DCI的搜索空间可相同,也可以不同,本申请实施例对此不做限定。
本申请实施例提供的多载波调度的方法,网络设备通过第一配置信息配置用于调度多载波的第一DCI和用于调度单载波的第二DCI,网络设备或终端设备基于两个DCI的不同的第一监听比特长度得到一个DCI长度,即第二监听比特长度,使得终端设备可以根据第二监听比特长度盲检DCI,减少了盲检复杂度,提高了系统传输性能,以及,通过第一DCI调度多个载波减少了PDCCH的资源开销。
以下,结合方法100,对网络设备配置有更多DCI的情况下的实施例做具体描述。
实施例A
可选地,上述第一配置信息还用于配置第三DCI,该第三DCI用于调度N个载波,N 为大于1的整数,该第三DCI的第一监听比特长度与该第一DCI的第三监听比特长度不同,该第一DCI的第一监听比特长度是根据该第一DCI的第三监听比特长度和该第三DCI的第一监听比特长度确定的;以及,该终端设备根据第二监听比特长度,监听该第一DCI和该第二DCI,包括:
该终端设备根据该第二监听比特长度,监听该第一DCI、该第二DCI和该第三DCI。
具体地,网络设备通过第一配置信息配置了3个DCI:第一DCI、第二DCI和第三DCI,第一DCI和第三DCI是多载波调度的DCI,第二DCI是单载波调度的DCI。为了减少盲检复杂度,终端设备将这3个DCI的监听比特长度对齐,得到第二监听比特长度,根据该第二监听比特长度监听3个DCI,以获得网络设备发送的DCI。
以下,对终端设备确定第二监听比特长度的过程做详细描述。
步骤1、终端设备确定第三DCI的第一监听比特长度和第一DCI的第三监听比特长度。
对于第三DCI的第一监听比特长度而言,在一示例中,终端设备可以仅通过上述第二配置信息的配置确定第三DCI的第一监听比特长度,在该示例中,第三DCI的第一监听比特长度是第三DCI的原始比特长度。在另一示例中,终端设备根据上述第二配置信息确定第三DCI的原始比特长度,对第三DCI的原始比特长度执行对齐操作得到对齐操作后的比特长度,在该示例中,第三DCI的第一监听比特长度是对第三DCI的原始比特长度执行对齐操作后得到的比特长度。
对于第一DCI的第三监听比特长度而言,在一示例中,终端设备可以仅通过第二配置信息的配置确定第一DCI的第三监听比特长度,在该示例中,第一DCI的第三监听比特长度是第一DCI的原始比特长度。在另一示例中,终端设备根据第二配置信息确定第一DCI的原始比特长度,对第一DCI的原始比特长度执行对齐操作得到对齐操作后的比特长度,在该示例中,第一DCI的第三监听比特长度是对第一DCI的原始比特长度执行对齐操作后得到的比特长度。
在一示例中,若第一DCI用于调度PUSCH,第三DCI用于调度PDSCH,则第三DCI的第一监听比特长度是通过第二配置信息配置的原始比特长度,第一DCI的第一监听比特长度以网络设备是否为终端设备配置SUL载波而确定。若网络设备为终端设备配置了SUL载波,PUSCH可以在SUL和non-SUL上发送,第一DCI可以调度SUL或non-SUL,若第一DCI的原始比特长度与调度另一个载波的DCI的原始比特长度不相等,则需要将第一DCI与调度另一个载波的DCI的原始比特长度对齐:若以调度另一个载波的DCI的原始比特长度作为基准,则需要对第一DCI的原始比特长度执行对齐操作,那么,第一DCI的第一监听比特长度为对第一DCI的原始比特长度执行对齐操作后得到的比特长度;若以第一DCI的原始比特长度作为基准,则不需要对第一DCI的原始比特长度执行对齐操作,那么,第一DCI的第一监听比特长度为第一DCI的原始比特长度。若网络设备没有为终端设备配置SUL载波,则第一DCI的第一监听比特长度为第一DCI的原始比特长度。在另一示例中,若第三DCI用于调度PUSCH,第一DCI用于调度PDSCH,则第一DCI的第一监听比特程度是通过第二配置信息配置的原始比特长度,第三DCI的第一监听比特长度以网络设备是否为终端设备配置SUL载波而确定,具体描述可参考上一示例关于第一DCI的第一监听比特长度的描述,将上一示例的第一DCI替换为第三DCI即可,不再赘述。
步骤2、终端设备根据该第三DCI的第一监听比特长度和该第一DCI的第三监听比特长度,确定该第一DCI的第一监听比特长度。
应理解,在步骤2中得到的第一DCI的第一监听比特长度,不仅是在执行完步骤2后得到的第一DCI的监听比特长度,也是执行完步骤2后得到的第三DCI的监听比特长度。
示例性地,第一DCI的第一监听比特长度可以与第三DCI的第一监听比特长度和第一DCI的第三监听比特长度中的任一个相同。
在步骤2中,终端设备可以将第三DCI的第一监听比特长度和第一DCI的第三监听比特长度对齐,得到第一DCI的第一监听比特长度。
在一些实施例中,可以以第三DCI的第一监听比特长度和第一DCI的第三监听比特长度中比特长度长的比特长度作为基准,对另一个DCI的比特长度执行对齐操作,得到第一DCI的第一监听比特长度,其中,这里的对齐操作是补零操作。
在一示例中,若第一DCI的第三监听比特长度比第三DCI的第一监听比特长度长,则以第一DCI的第三监听比特长度作为基准,将第三DCI的第一监听比特长度与第一DCI的第三监听比特长度对齐,得到第一DCI的第一监听比特长度。在该示例中,第一DCI的第一监听比特长度与第一DCI的第三监听比特长度相同,可以是第一DCI的原始比特长度,也可以对第一DCI的原始比特长度执行对齐操作后得到的比特长度,具体以步骤1中确定的第一DCI的第三监听比特长度而定。
在另一示例中,若第三DCI的第一监听比特长度比第一DCI的第三监听比特长度长,则以第三DCI的第一监听比特长度作为基准,将第一DCI的第三监听比特长度与第三DCI的第一监听比特长度对齐,得到第一DCI的第一监听比特长度。在该示例中,第一DCI的第一监听比特长度与第三DCI的第一监听比特长度相同,可以是第三DCI的原始比特长度,也可以对第三DCI的原始比特长度执行对齐操作后得到的比特长度,具体以步骤1中确定的第三DCI的第一监听比特长度而定。
在另一些实施例中,可以以第三DCI的第一监听比特长度和第一DCI的第三监听比特长度中比特长度短的比特长度作为基准,对另一个DCI的比特长度执行对齐操作,得到第一DCI的第一监听比特长度,其中,这里的对齐操作是截短操作。
在一示例中,若第一DCI的第三监听比特长度比第三DCI的第一监听比特长度短,则以第一DCI的第三监听比特长度作为基准,将第三DCI的第一监听比特长度与第一DCI的第三监听比特长度对齐,得到第一DCI的第一监听比特长度。
在另一示例中,若第三DCI的第一监听比特长度比第一DCI的第三监听比特长度短,则以第三DCI的第一监听比特长度作为基准,将第一DCI的第三监听比特长度与第三DCI的第一监听比特长度对齐,得到第一DCI的第一监听比特长度。
步骤3、终端设备根据该第一DCI的第一监听比特长度和该第二DCI的第一监听比特长度,确定该第二监听比特长度。
示例性地,第二监听比特长度可以与第一DCI的第一监听比特长度和第二DCI的第一监听比特长度中的任一个相同。
关于步骤3的具体描述可参考上文关于根据第一DCI的第一监听比特长度和第二DCI的第一监听比特长度确定第二监听比特长度的过程的相关描述,不再赘述。
对于网络设备而言,网络设备采用与终端设备相同的方式确定第二监听比特长度。在确定第二监听比特长度后,网络设备根据第二监听比特长度,发送第一DCI、第二DCI和第三DCI中的至少一个。
在该实施例中,第一DCI的格式可以为可以为上文的mDCI中的一例,第三DCI的格式可以为上文的mDCI的另一例。例如,第一DCI的格式为DCI format 0_3,第三DCI的格式为DCI format 1_3。再例如,第一DCI的格式为DCI format 1_3,第三DCI的格式为DCI format 0_3。
在上述第一DCI的M个载波和第三DCI调度的N个载波中,该M个载波和该N个载波可以具有相同的载波,也可以不具有相同的载波。
对于一个小区调度多个载波的情况,该M个载波和该N个载波属于同一个小区对应的载波。在一示例中,该M个载波和该N个载波可以具有相同的载波。例如,小区1对应3个载波,载波1、载波2和载波3,M=2,N=2,第一DCI调度的2个载波是小区1对应的载波1和载波2,第三DCI调度的2个载波是小区1对应的载波2和载波3,第一DCI调度的2个载波和第三DCI调度的2个载波具有相同的载波2。再例如,小区1对应2个载波,载波1和载波2,M=2,N=2,第一DCI调度的2个载波是小区1对应的载波1和载波2,第三DCI调度的2个载波是小区1对应的载波1和载波2,第一DCI调度的2个载波和第三DCI调度的2个载波具有相同的载波1和载波2,两个DCI调度的载波相同。
对于一个小区调度一个载波的情况,该M个载波属于至少两个小区对应的载波,该N个载波属于至少两个小区对应的载波,该M个载波与该N个载波具有相同的载波,该载波是一个小区对应的载波。例如,M=2,第一DCI调度载波1和载波2,载波1是小区1对应的载波,载波2是小区2对应的载波,N=2,第三DCI调度载波2和载波3,载波2是小区2对应的载波,载波3是小区3对应的载波,第一DCI调度的2个载波和第三DCI调度的2个载波具有相同的载波2,载波2是小区2对应的载波。可选地,上述第一配置信息还用于配置第三DCI的搜索空间。其中,第三DCI的搜索空间、第一DCI的搜索空间和第二DCI的搜索空间可相同,也可以不同,本申请实施例对此不做限定。例如,第一DCI和第三DCI的搜索空间相同,第二DCI的搜索空间与第一DCI和第三DCI的搜索空间不同。
本申请实施例提供的多载波调度的方法,网络设备通过第一配置信息还配置了用于调度多个载波的第三DCI,终端设备或网络设备将第一DCI、第二DCI和第三DCI的比特长度统一为第二监听比特长度,使得终端设备可以根据第二监听比特长度盲检DCI,减少了盲检复杂度,提高了系统传输性能。并且,由于第一DCI和第三DCI都是多载波调度的DCI,所以,第一DCI的第三监听比特长度和第三DCI的第一监听比特长度之间的差异不是很大,因此,先根据第一DCI的第三监听比特长度和第三DCI的第一监听比特长度得到第一DCI的第一监听比特长度后,再根据第一DCI的第一监听比特长度和第二DCI的第一监听比特长度得到第二监听比特长度,在将第一DCI的第三监听比特长度与第三DCI的第一监听比特长度的对齐的过程中,在需要以第一DCI的第三监听比特长度和第三DCI的第一监听比特长度中的任一个比特长度作为基准且对另一个DCI的比特长度执行补零操作的情况下,不会增加较多的比特数,可以避免DCI长度对齐过程中可能增加的大量开销的问题。
如上文所述,在DCI长度预算(DCI size budget)中,经C-RNTI加扰的不同的DCI长度不超过3个,在DCI较多的情况下,可以将DCI长度控制在3个以内即可。应理解,这里所说的DCI长度是终端设备盲检过程中使用的DCI长度,例如第二监听比特长度、下文的第四监听比特长度和第五监听比特长度。
下面,对满足3个DCI长度的实施例做说明。
实施例B
可选地,该第一配置信息还用于配置第四DCI和第五DCI,该第四DCI和该第五DCI各自用于调度一个载波;以及,该终端设备根据第二监听比特长度,监听该第一DCI和该第二DCI,包括:
该终端设备根据该第二监听比特长度、第四监听比特长度和第五监听比特长度,监听该第一DCI、该第二DCI、该第四DCI和该第五DCI,其中,该第二监听比特长度、该第四监听比特长度和该第五监听比特长度均不同,该第四监听比特长度是该第四DCI的监听比特长度,该第五监听比特长度是该第五DCI的监听比特长度。具体地,网络设备通过第一配置信息配置了4个DCI:第一DCI、第二DCI、第四DCI和第五DCI,第一DCI是多载波调度的DCI,第二DCI、第四DCI和第五DCI是单载波调度的DCI,每个DCI具有各自的原始比特长度。若各个DCI的原始比特长度不同,4个DCI对应4个DCI长度,不满足DCI长度预算。因此,根据4个DCI的原始比特长度,对DCI执行对齐操作,最终得到3个监听比特长度,即第二监听比特长度、第四监听比特长度和第五监听比特长度,刚好满足DCI长度预算。
在该实施例中,第二监听比特长度是根据第一DCI的第一监听比特长度和第二DCI的第一监听比特长度确定的,可以是第一DCI的原始比特长度或对第一DCI的原始比特长度执行对齐操作后得到的比特长度,也可以是第二DCI的原始比特长度或对第二DCI的原始比特长度执行对齐操作后得到的比特长度,具体参考上文描述。

对于网络设备而言,网络设备采用与终端设备相同的方式确定第二监听比特长度、第四监听比特长度和第五监听比特长度。在确定第二监听比特长度、第四监听比特长度和第五监听比特长度后,网络设备根据第二监听比特长度、第四监听比特长度和第五监听比特长度中的至少一个,发送第一DCI、第二DCI、第四DCI和第五DCI中的至少一个。
应理解,网络设备发送至少一个DCI时,会按照确定好的DCI的监听比特长度发送该DCI。
若网络设备发送第一DCI和第二DCI中的至少一个,则根据第二监听比特长度发送第一DCI和第二DCI中的至少一个;若网络设备发送第四DCI,则根据第四监听比特长度发送第四DCI;若网络设备发送第五DCI,则根据第五监听比特长度发送第五DCI。
在该实施例中,第一DCI可以为上文的mDCI的一例,例如,第一DCI的格式为可 以为上文的DCI format 0_3或DCI format 1_3。第二DCI、第四DCI和第五DCI可以分别为上文的sDCI的任一例,第二DCI、第四DCI和第五DCI的格式都不同。例如,第二DCI的格式为CSS中的DCI format 0_0、CSS中的DCI format 1_0、USS中的DCI format0_0或USS中的DCI format 1_0,第四DCI为USS中的DCI format 0_1或USS中的DCI format 1_1,第五DCI为USS中的DCI format 0_2或USS中的DCI format 1_2。再例如,第二DCI为USS中的DCI format 0_1或USS中的DCI format 1_1,第四DCI为USS中的DCI format 0_2或USS中的DCI format 1_2,第五DCI的格式为CSS中的DCI format 0_0、CSS中的DCI format 1_0、USS中的DCI format0_0或USS中的DCI format 1_0。
应理解,上述第二DCI、第四DCI和第五DCI各自调度的一个载波是同一个小区对应的载波,这3个DCI调度的载波可以至少部分相同,也可以各不相同。
对于一个小区调度多个载波的情况,第二DCI、第四DCI和第五DCI调度的3载波可以至少部分相同,也可以各不相同。例如,小区1对应3个载波,载波1、载波2和载波3,第二DCI调度载波1,第四DCI调度载波2,第五DCI调度载波3,3个DCI调度的载波各不相同。再例如,小区1对应载波1、载波2和载波3,第二DCI调度载波1,第四DCI调度载波2,第五DCI调度载波2,3个DCI调度的载波中有2个载波相同。再例如,小区1对应载波1、载波2和载波3,第二DCI、第四DCI、第五DCI均调度载波1,3个DCI调度的载波相同。
对于一个小区调度一个载波的情况,上述3个DCI调度同一个载波。
可选地,上述第一配置信息还用于配置第四DCI的搜索空间和第五DCI的搜索空间。其中,第四DCI的搜索空间、第五DCI的搜索空间、第一DCI的搜索空间和第二DCI的搜索空间可相同,也可以不同,本申请实施例对此不做限定。例如,第一DCI的搜索空间与其余3个DCI的搜索空间都不同,该其余3个DCI中任意两个DCI的搜索空间相同。再例如,上述4个DCI的搜索空间均不相同。
实施例C
可选地,该第一配置信息还用于配置第三DCI、第六DCI、第七DCI、第八DCI、第九DCI和第十DCI,该第三DCI用于调度N个载波,N为大于1的整数,该第六DCI、第七DCI、第八DCI、第九DCI和第十DCI各自用于调度一个载波,该第三DCI的第一监听比特长度与该第一DCI的第三监听比特长度均不同,该第一DCI的第一监听比特长度是根据该第一DCI的第三监听比特长度和该第三DCI的第一监听比特长度确定的;以及,
该终端设备根据该第二监听比特长度、第四监听比特长度和第五监听比特长度,监听该第一DCI、该第二DCI、该第四DCI和第五DCI,包括:
该终端设备根据该第二监听比特长度、该第四监听比特长度和该第五监听比特长度,监听该第一DCI、该第二DCI、该第三DCI、该第四DCI、该第五DCI、该第六DCI、该第七DCI、该第八DCI、该第九DCI和该第十DCI。
其中,第二监听比特长度是第一DCI、第二DCI、第三DCI和第六DCI的监听比特长度,第四监听比特长度是第四DCI和第七DCI的监听比特长度,第五监听比特长度是第五DCI、第八DCI、第九DCI和第十DCI的监听比特长度。
具体地,网络设备通过第一配置信息配置了10个DCI:第一DCI、第二DCI、第三 DCI、第四DCI、第五DCI、第六DCI、第七DCI、第八DCI、第九DCI和第十DCI,第一DCI和第二DCI是多载波调度的DCI,其余8个DCI都是单载波调度的DCI,每个DCI具有各自的原始比特长度。若各个DCI的原始比特长度不同,10个DCI对应10个DCI长度,不满足DCI长度预算。因此,根据10个DCI的原始比特长度,对DCI执行对齐操作,最终得到3个监听比特长度,即第二监听比特长度、第四监听比特长度和第五监听比特长度,满足DCI长度预算。
在该实施例中,第一DCI的第一监听比特长度是根据该第一DCI的第三监听比特长度和该第三DCI的第一监听比特长度确定的,第二DCI的第一监听比特长度是根据该第二DCI的第六监听比特长度和该第六DCI的第一监听比特长度确定的,第二监听比特长度是根据第一DCI的第一监听比特长度和第二DCI的第一监听比特长度确定的,第四监听比特长度是根据该第四DCI的第一监听比特长度和该第七DCI的第一监听比特长度确定的,该第五监听比特长度是根据该第五DCI的第一监听比特长度、该第八DCI的第一监听比特长度、该第九DCI的第一监听比特长度和该第十DCI的第一监听比特长度确定的。

应理解,在步骤3中得到的第二DCI的第一监听比特长度,不仅是在执行完步骤3后得到的第二DCI的监听比特长度,也是执行完步骤3后得到的第六DCI的监听比特长度。
终端设备可以根据上述第二配置信息确定第二DCI的第六监听比特长度,第二DCI的第 六监听比特长度可以是第二DCI的原始比特长度,也可以是对第二DCI的原始比特长度执行对齐操作后得到的比特长度。终端设备可以根据上述第二配置信息确定第六DCI的第一监听比特长度,可以是第六DCI的原始比特长度,也可以是对第六DCI的原始比特长度执行对齐操作后得到的比特长度。

示例1,若第六DCI的第一监听比特长度和第二DCI的第六监听比特长度相同,则将第六DCI的第一监听比特长度和第二DCI的第六监听比特长度确定为第二DCI的第一监听比特长度。
在该示例中,以表12对应的实施例五为例,步骤3可对应实施例五的步骤3A,不执行步骤5C,得到的DCI format 0_1的size C(例如,第二DCI第六监听比特长度)和DCI format 1_1的size D(例如,第六DCI的第一监听比特长度)相同,是一个比特长度(或DCI长度),将该比特长度作为第二DCI的第一监听比特长度,以将该第二DCI的第一监听比特长度与其他DCI的比特长度对齐。

在根据第四DCI的第一监听比特长度和第七DC的第一监听比特长度确定第四监听比特长度的过程中,将第四DCI的第一监听比特长度和第七DC的第一监听比特长度对齐,得到第四监听比特长度。示例性地,第四监听比特长度与第四DCI的第一监听比特长度和第七DC的第一监听比特长度中的任一个相同。例如,以第四DCI的第一监听比特长度和第七DC的第一监听比特长度中比特长度长的比特长度作为基准,对另一个DCI的比特长度执行对齐操作,得到第四监听比特长度,这里的对齐操作是补零操作。再例如,以第四DCI的第一监听比特长度和第七DC的第一监听比特长度中比特长度短的比特长度作为基准,对另一个DCI的比特长度执行对齐操作,得到第四监听比特长度,这里的对齐操作是截短操作。
在该示例中,以表12对应的实施例五为例,步骤5可对应实施例五的步骤3B和5B, 通过步骤3B得到的DCI format 0_2的size M(例如,第四DCI的第一监听比特长度)和DCI format 1_2的size N(例如,第七DCI的第一监听比特长度)不同,通过步骤5B将size M和size N对齐,得到size K(例如,第四监听比特长度)。

终端设备可以根据上述第二配置信息确定第五DCI、第八DCI、第九DCI、第十DCI的第一监听比特长度,每个DCI的第一监听比特长度可以原始比特长度,也可以是对DCI的原始比特长度执行对齐操作后得到的比特长度。
在一些实施例中,第五DCI的第一监听比特长度和第八DCI的第一监听比特长度相同,第九DCI的第一监听比特长度和第十DCI的第一监听比特长度相同。

这样,经过上述步骤1至步骤6,得到第二监听比特长度、第四监听比特长度和第五监听比特长度,根据这三个监听比特长度监听上述10个DCI,以减少盲检复杂度。

对于网络设备而言,网络设备采用与终端设备相同的方式确定第二监听比特长度、第四监听比特长度和第五监听比特长度。在确定第二监听比特长度、第四监听比特长度和第五监听比特长度后,网络设备根据第二监听比特长度、第四监听比特长度和第五监听比特长度中的至少一个,发送上述10个DCI中的至少一个。

具体地,网络设备通过第一配置信息配置了10个DCI:第一DCI、第二DCI、第三DCI、第四DCI、第五DCI、第六DCI、第七DCI、第八DCI、第九DCI和第十DCI,第一DCI和第二DCI是多载波调度的DCI,其余8个DCI都是单载波调度的DCI,每个DCI具有各自的原始比特长度。若各个DCI的原始比特长度不同,10个DCI对应10个DCI长度,不满足DCI长度预算。因此,根据10个DCI的原始比特长度,对DCI执行对齐操作,最终得到3个监听比特长度,即第二监听比特长度、第四监听比特长度和第五监听比特长度,满足DCI长度预算。
在该实施例中,该第二DCI的第一监听比特长度是根据该第二DCI的第七监听比特长度、该第八DCI的第一监听比特长度、该第九DCI的第一监听比特长度和该第十DCI的第一监听比特长度确定的,该第四监听比特长度是根据该第四DCI的第一监听比特长度和该第七DCI的第一监听比特长度确定的,该第五监听比特长度是根据该第五DCI的第一监听比特长度和该第六DCI的第一监听比特长度确定的。

步骤3、终端设备根据第二DCI的第七监听比特长度、第八DCI的第一监听比特长度、第九DCI的第一监听比特长度和第十DCI的第一监听比特长度,确定第二DCI的第一监听比特长度。
步骤3中确定第二DCI的第一监听比特长度与实施例C中步骤6确定第五监听比特长度的过程类似,将实施例C的第五DCI的第一监听比特长度替换为这里的第二DCI的第七监听比特长度,将实施例C的第五监听比特长度替换为这里的第二DCI的第一监听比特长度即可,具体描述可参考实施例C的步骤6的相关描述,不再赘述。

这样,经过上述步骤1至步骤6,得到第二监听比特长度、第四监听比特长度和第五监听比特长度,根据这三个监听比特长度监听上述10个DCI。
应理解,本申请实施例对上述步骤1至步骤6的执行顺序不做任何限定,上述各个步骤的编号不代表执行的先后顺序,以各个步骤实现的内在逻辑为准。
在该实施例中,第一DCI和第三DCI可以为上文的mDCI的任一例,第一DCI和第三DCI的格式不同,例如,第一DCI的格式为DCI format 0_3和DCI format 1_3中的一个,第三DCI的格式为DCI format 0_3和DCI format 1_3中的另一个。其余的8个DCI可以为上文的sDCI的任一例,且8个DCI的格式各不相同。其中,第二DCI、第八DCI、第九DCI、第十DCI为同系列的DCI,对应0系列的DCI格式,各自CSS中的DCI format 0_0、CSS中的DCI format 1_0、USS中的DCI format 0_0、USS中的DCI format 1_0。第四DCI和第七DCI为同系列的DCI,第五DCI和第六DCI为同系列的DCI,第四DCI和第七DCI可对应2系列和1系列中的任一系列的DCI格式,第五DCI和第六DCI对应2系列和1系列中的另一个DCI格式,每个DCI对应一个DCI格式。
对于网络设备而言,网络设备采用与终端设备相同的方式确定第二监听比特长度、第四监听比特长度和第五监听比特长度。在确定第二监听比特长度、第四监听比特长度和第五监听比特长度后,网络设备根据第二监听比特长度、第四监听比特长度和第五监听比特长度中的至少一个,发送上述10个DCI中的至少一个。
应理解,网络设备发送上述10个DCI中的至少一个时,会按照确定好的DCI的监听比特长度发送该DCI。例如,根据第二监听比特长度发送第一DCI、第二DCI、第三DCI、第八DCI、第九DCI和第十DCI中的至少一个,根据第四监听比特长度发送第四DCI和第七DCI中的至少一个,根据第五监听比特长度发送第五DCI和第六DCI中的至少一个。
可选地,该第一DCI包括第一类域和第二类域中的至少一个,该第一类域包括至少一个共享域,该第二类域包括至少一个独立域,该共享域承载的信息是在该M个载波上传输的数据信道共用的信息,该独立域包括M个子域,该M个子域与该M个载波一一对应,每个子域承载的信息与在对应的载波上传输的数据信道相关。
其中,第一DCI包括第一类域和第二类域中的至少一个,表示,第一DCI包括第一类域,或,第一DCI包括第二类域,或,第一DCI包括第一类域和第二类域。
第一DCI包括第一类域的情况可参考上文第一方面中mDCI的第三种DCI格式的具体描述,不再赘述。
第一DCI包括第二类域的情况可参考上文第一方面中mDCI的第二种DCI格式的具体描述,不再赘述。
第一DCI包括第一类域和第二类域的情况可参考上文第一方面中mDCI的第一种DCI格式的具体描述,不再赘述。
可选地,该方法还包括:
网络设备发送第二配置信息,该第二配置信息包括M个载波配置信息,该M个载波配置信息与该M个载波一一对应,以及,该独立域的每个子域的比特长度是根据对应的载波配置信息确定的,该共享域的比特长度是基于预定义方式确定的。对应地,终端设备接收该第二配置信息。
也就是说,终端设备可以根据该第二配置信息,确定第一DCI中每个共享域和每个独立域的比特长度,从而得到该第一DCI的原始比特长度,从而,可以根据第一DCI的原始比特长度确定第一DCI的第一监听比特长度以及最终用于盲检的第二监听比特长度,实现盲检过程。
对于独立域,可以根据M个载波配置信息确定每个独立域中M个子域的比特长度,从而,确定所有独立域的比特长度。具体描述可参考上文第一方面中mDCI的第一种DCI格式中确定独立域的比特长度的相关描述,不再赘述。
对于共享域,可以根据预定义方式确定每个共享域的比特长度,该预定义方式与M个载波配置信息至少一个载波配置信息相关。也就是说可以根据M个载波配置信息中的至少一个载波配置信息确定每个共享域的比特长度,从而,确定所有共享域的比特长度。在一些实施例中,根据M个载波配置信息中的任一个载波配置信息确定每个共享域的比特长度,M个载波配置信息中的任一个载波配置信息是M个载波配置信息中的部分载波配置信息。在另一些实施例中,根据M个载波配置信息确定每个共享域的比特长度,M个载波配置信息是M个载波配置信息中的全部载波配置信息。具体描述可参考上文第一方面中mDCI的第一种DCI格式中确定共享域的比特长度的相关描述,不再赘述。
图13是申请实施例提供的多载波调度的方法200的示意性结构图。该方法200可适用于图1所示的通信系统中,由网络设备和终端设备执行。
在S210中,网络设备发送第一配置信息,该第一配置信息用于配置第一下行控制信息DCI,该第一DCI用于调度M个载波,该M个载波中的第一载波对应第一辅小区,M为大于1的整数。对应地,终端设备接收该第一配置信息。
在S220中,网络设备根据该第一DCI的监听比特长度,发送该第一DCI。
在S230中,终端设备根据该第一DCI的监听比特长度,监听该第一DCI,其中,该第一辅小区对应的监听比特长度包括该第一DCI的监听比特长度,该第一辅小区对应的监听比特长度的数量小于或等于预设数量。示例性地,该预设数量为3。
具体地,网络设备通过第一配置信息为终端设备配置多载波调度的第一DCI,终端设备或网络设备确定第一DCI的监听比特长度,以便于终端设备根据第一DCI的监听比特长度监听第一DCI,完成盲检过程。在第一DCI调度的第一载波对应第一辅小区时,将第一DCI的监听比特长度(或DCI长度)划分至第一辅小区对应的监听比特长度中,以满足第一辅小区对应的监听比特长度的数量小于或等于预设数量的要求,
应理解,第一辅小区对应的监听比特长度表示的是最终用于盲检的监听比特长度。下面描述的DCI的监听比特长度也为最终用于盲检的监听比特长度。
对于辅小区(例如,第一辅小区)而言,现有的单载波调度的DCI format x_1和DCI format x_2的DCI的监听比特长度(或DCI长度)属于辅小区对应的监听比特长度,一个系列的DCI格式对应一个监听比特长度,2个系列的DCI格式分别对应2个监听比特长度, 若辅小区对应的监听比特长度的数量为3,则还剩余1个监听比特长度。所以,将多载波调度的DCI(例如,第一DCI)的监听比特长度划分至辅小区对应的监听比特长度,这样,辅小区最多对应3个监听比特长度,满足辅小区对应的监听比特长度的数量为3的要求。
本申请实施例提供的多载波调度的方法,将多载波调度的第一DCI的监听比特长度划分至第一辅小区对应的监听比特长度中,即,第一辅小区对应的监听比特长度包括第一DCI的监听比特长度,这样,在网络设备配置有多个单载波调度的DCI和多个多载波调度的DCI的情况下,可以在不需要将多载波调度的DCI与单载波调度的DCI的比特长度对齐的情况下,使得所有DCI的监听比特长度满足第一辅小区对应的监听比特长度的数量小于或等于预设数量(例如,3)的要求,减少了确定DCI的监听比特长度的过程的复杂度,易于实现。
可选地,用于承载第一DCI的载波是该M个载波中的任一个载波,或,用于承载第一DCI的载波与该M个载波不同。
也就是说,若用于承载第一DCI的载波是M个载波中的任一个载波,则第一DCI可以是调度载波,若用于承载第一DCI的载波与M个载波不同,则第一DCI是被调度载波,
需要说明的是,小区对应的监听比特长度的数量可以理解为上文所述的小区对应的DCI长度预算,DCI长度预算小于或等于预设数量,对于第一辅小区而言,第一辅小区对应的监听比特长度的数量可以理解为上第一辅小区对应的DCI长度预算。
本申请实施例的方法200与上文第二方面的实施例八类似,第一DCI可以为mDCI的任一例,第一辅小区可为任一个辅小区,关于方法200的具体描述可参考实施例八的相关描述。

在S320中,网络设备发送该第一DCI。
在S330中,终端设备监听该第一DCI。
可选地,该方法还包括:
网络设备发送第二配置信息,该第二配置信息包括M个载波配置信息,该M个载波配置信息与该M个载波一一对应,以及,该独立域的每个子域的比特长度是基于对应的载波配置信息确定的,该共享域的比特长度是基于预定义方式确定的。对应地,终端设备接收该第二配置信息。
在该实施例中,第一DCI包括第一类域和第二类域中的至少一个,表示,第一DCI包括第一类域,或,第一DCI包括第二类域,或,第一DCI包括第一类域和第二类域。
第一DCI包括第一类域的情况可参考上文第一方面中mDCI的第三种DCI格式的具 体描述,不再赘述。
第一DCI包括第二类域的情况可参考上文第一方面中mDCI的第二种DCI格式的具体描述,不再赘述。
第一DCI包括第一类域和第二类域的情况可参考上文第一方面中mDCI的第一种DCI格式的具体描述,不再赘述。
需要说明的是,方法100、200和300中描述的第一配置信息和第二配置信息可以是上文第一方面、第二方面和第三方面中所述的配置信息中的两个配置信息,在上文中,以配置信息具体实现的功能来对应方法100、200和300中的第一配置信息和第二配置信息。
