本申请主张在2020年05月20日在中国提交的中国专利申请号No.202010432806.3的优先权,其全部内容通过引用包含于此。
技术领域
本申请属于通信技术领域,具体涉及一种多载波调度方法、装置及设备。
背景技术
通常,为了增强控制信道覆盖,会将一些小区部署在低频段载波(carrier,CC)。由于低频段CC的带宽有限,因此一个下行控制信息(downlink control information,DCI)调度一个小区的设计会导致小区的下行控制信令开销较大,从而影响通信系统的容量。对此,提出了一个DCI同时动态调度多个小区或多个CC的设计,以减小下行控制信令开销。
然而,在用户设备(user equipment,UE)支持使用一个DCI同时动态调度多个CC,且每个CC配置了至少一个半静态配置,例如下行半静态调度(downlink semi-persistent scheduling,DL SPS)和/或至少一个上行配置授权(uplink configured grant,UL CG)的情况下,由于来自一个调度小区(the scheduling cell)的DCI只能半静态调度自小区(self-carrier)或者被调度小区(the scheduled cell)的一个半静态配置,因此可能需要采用多个DCI用于调度多个CC上的半静态配置,从而导致下行控制信令的开销较大,并且增加了UE检测下行控制信令的复杂度。
发明内容
本申请实施例的目的是提供一种多载波调度方法、装置及设备,能够解决采用多个DCI调度多个CC上的半静态配置导致下行控制信令的开销较大,且增加了检测下行控制信令的复杂度的技术问题。

第四方面,本申请实施例提供了一种多载波调度装置。该装置包括发送模块。发送模块,用于向UE发送DCI,该DCI用于指示在M个载波上进行半静态配置的调度,或者指示在X个载波上进行半静态配置的调度和在Y个载波上进行动态配置的调度,该M个载波、该X个载波和该Y个载波均为该DCI支持调度的N个载波中的载波。其中,M和N均为大于或等于2的整数,X和Y均为正整数,且M小于或等于N,X和Y之和小于或等于N。
第五方面,本申请实施例提供了一种UE,该UE包括处理器、存储器及存储在该存储器上并可在该处理器上运行的程序或指令,该程序或指令被该处理器执行时实现如第一方面提供的方法的步骤。

具体实施方式
下面将结合本申请实施例中的附图,对本申请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申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,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,都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象,而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换,以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施。此外,说明书以及权利要求中“和/或”表示所连接对象的至少其中之一,字符“/”,一般表示前后关联对象是一种“或”的关系。
目前,新空口(new radio,NR)系统支持为UE配置一个或多个CC(或小区)。当UE配置为单载波模式或载波聚合(carrier aggregation,CA)下的自小区调度或跨载波(cross-carrier)调度模式时,每个来自调度小区的DCI只能调度自小区或者被调度小区的一个配置。
在相关协议中,下行传输方式和上行传输方式均分为基于动态配置的传输方式和基于半静态配置的传输方式。例如,下行传输方式的半静态配置可以为DL SPS,上行传输方式的半静态配置可以为UL CG。
基于动态配置的传输方式,其特点为传输参数如时域频域资源、调制和编码方案(modulation and coding scheme,MCS)、解调参考信号(demodulation reference signal,DMRS)的配置由负责调度的DCI动态指示,并且该传输为一次性传输。
对于半静态配置的传输方式,以半静态配置为DL SPS为例,DL SPS传输参数由高层和物理层共同配置和指示,高层主要半静态的配置传输资源的周期,物理层主要用于激活DCI指示传输参数如MCS、时频资源等。
一个DCI是激活/去激活DL SPS的DCI还是动态调度的DCI,是根据加扰携带该DCI PDCCH的循环冗余校验(cyclic redundancy check,CRC)的不同无线网络临时标识(radio network temporary identifier,RNTI)来区分的。加扰半静态调度的物理下行控制信道(physical downlink control channel,PDCCH)的CRC的RNTI是配置调度无线网络临时标识(configured scheduling RNTI,CS-RNTI);加扰动态调度的PDCCH的CRC的RNTI是小区无线网络临时标识(cell RNTI,C-RNTI)。一个DCI是DL SPS激活DCI还是去激活DCI,是根据设置DCI中一些域(field)特殊的值来进行区分的。
表1是当为一个UE提供了一个DL SPS或UL CG配置时,调度激活该DL SPS或UL CG 配置的特定域(special field)。

从上述表1至表4,可以看出,激活和去激活DCI可以通过调制编码方案(modulation and coding scheme,MCS)field以及频域资源分配(frequency domain resource assignment,FDRA)field里的值不同进行区分。当一个CC上配置了一个DL SPS时,自动混合请求重传(hybrid automatic repeat request,HARQ)进程编号(process number)(HPN)可以配置为固定值0,以作为虚拟CRC(virtual CRS)来降低激活/去激活DCI检测的虚警概率,并增强检测鲁棒性。当一个CC上配置了多个DL SPS时,HPN是用来指示相应激活、去激活配置(configuration)的索引(index),不再设置为固定值。此外,当一个CC上配置了多个DL SPS时,对于激活DCI,仅支持一个DCI激活一个CC上的一个DL SPS;对于去激活DCI,除了支持一个DCI去激活一个CC上的一个DL SPS,还支持一个DCI去激活一个CC上的多个DL SPS。
在UE支持使用一个DCI同时动态调度多个CC,且每个CC配置了至少一个半静态配置,例如DL SPS和/或至少一个UL CG的情况下,由于来自一个调度小区的DCI只能半静 态调度自小区或者被调度小区的一个半静态配置,因此可能需要采用多个DCI用于调度多个CC上的半静态配置,从而导致下行控制信令的开销较大,并且增加了UE检测下行控制信令的复杂度。
为此,本申请实施例提供了一种多载波调度方法、装置、设备及系统,UE可以接收网络设备发送的DCI,该DCI用于指示在M个载波上进行半静态配置的调度,或者指示在X个载波上进行半静态配置的调度和在Y个载波上进行动态配置的调度,该M个载波、该X个载波和该Y个载波均为该DCI支持调度的N个载波中的载波。其中,M和N均为大于或等于2的整数,X和Y均为正整数,且M小于或等于N,X和Y之和小于或等于N。通过该方案,在一个DCI支持调度N个载波的情况下,一种方式为,网络设备可以通过一个DCI指示UE在N个载波中的多个载波上进行半静态配置的调度,另一种方式为,网络设备可以通过一个DCI指示UE在N个载波中的一部分载波上进行半静态配置的调度,并在N个载波中的另一部分载波上进行动态配置的调度。因此网络设备无需下发多个DCI,从而降低了下行控制信令的开销,并降低了UE检测下行控制信令的复杂度。
图1示出了本申请实施例提供的一种通信系统的架构示意图。如图1所示,该通信系统可以包括UE 01和网络设备02。
需要说明的是,本申请实施例中,上述如图1所示的各个设备之间可以是无线连接,也可以是有线连接。如图1所示的通信系统可以为NR系统或后续演进系统,本申请实施例均不作具体限定,可以根据实际使用需求确定。
UE是一种向用户提供语音和/或数据连通性的设备,具有有线/无线连接功能的手持式设备,或连接到无线调制解调器的其他处理设备。UE可以经过无线接入网(radio access network,RAN)与一个或多个核心网设备进行通信。UE可以是终端设备,例如移动终端,如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机,也可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置,它们与RAN交换语言和/或数据,例如,个人通信业务(personal communication service,PCS)电话、无绳电话、会话发起协议(SIP)话机、无线本地环路(wireless local loop,WLL)站、个人数字助理(personal digital assistant,PDA)等设备。终端设备也可以称为用户代理(user agent)等。
网络设备是一种部署在RAN中用于为UE提供无线通信功能的设备。本申请实施例中,网络设备可以为基站,且基站可以包括各种形式的宏基站、微基站、中继站、接入点等等。在采用不同的无线接入技术的系统中,具备基站功能的设备的名称可能会有所不同。例如,在第五代无线通信(5-generation,5G)系统中,可以称为5G系统基站(gNB);在第四代无线通信(4-generation,4G)系统,如长期演进(long term evolution,LTE)系统中,可以称为演进型基站(evolved NodeB,eNB);在第三代移动通信(3-generation,3G)系统中,可以称为基站(Node B)。随着通信技术的演进,“基站”这一名称可能会发生变化。
基于如图1所示的通信系统,如图2所示,本申请实施例提供了一种多载波调度方法。
S201、网络设备向UE发送DCI,该DCI用于指示在M个载波上进行半静态配置的调度,或者指示在X个载波上进行半静态配置的调度和在Y个载波上进行动态配置的调度。
S202、接收网络设备发送的DCI。
其中,M个载波、X个载波和Y个载波均为DCI支持调度的N个载波中的载波。M和N均为大于或等于2的整数,X和Y均为正整数,且M小于或等于N,X和Y之和小于或 等于N。
本申请实施例中,上述网络设备向UE发送的DCI的数量为一个,因此可称为single DCI。该single DCI可以指示在该single DCI支持调度的N个载波中的多个载波上进行半静态配置的调度;或者,该single DCI可以指示在该single DCI支持调度的N个载波中的至少一个载波上进行半静态配置的调度,并在该N个载波中的其他至少一个载波上进行动态配置的调度。
可选的,上述半静态配置可以包括以下至少一项:DL SPS、UL CG、上行半静态信道状态信息(semi-persistent channel state information,semi-persistent CSI)、上行半静态探测参考信号(semi-persistent sounding reference signal,semi-persistent SRS)。
可选的,上述动态配置包括以下至少一项:物理下行共享信道(physical downlink shared channel,PDSCH)、物理上行共享信道(physical uplink shared channel,PUSCH)、非周期信道状态信息(aperiodic semi-persistent,aperiodic CSI)、非周期探测参考信号(aperiodic sounding reference signal,aperiodic SRS)。
需要说明的是,上述半静态配置和动态配置均为示例性说明,可以理解,也可以为其他任意可能的半静态配置和动态配置,本申请实施例不作限定。
可选的,一种可选的实现方式为,M个载波或X个载波中每个载波上的半静态配置的数量为一个。示例性的,假设single DCI支持调度CC#0、CC#1、CC#2、CC#3、CC#4和CC#5。single DCI可以指示在CC#0和CC#1上进行半静态配置的调度,且CC#0和CC#1上的半静态配置的数量均为一个。
另一种可选的实现方式为,M个载波或X个载波中,至少一个载波中的每个载波上的半静态配置的数量为至少一个。示例性的,假设single DCI支持调度CC#0、CC#1、CC#2、CC#3、CC#4和CC#5。single DCI可以指示在CC#0和CC#1上进行半静态配置的调度,且CC#0上的半静态配置的数量为一个,CC#1上的半静态配置的数量为多个。
可选的,上述DCI可以承载在N个载波中的一个载波上;或者,上述DCI承载在与N个载波不同的载波上。
示例性的,假设single DCI支持调度CC#0、CC#1、CC#2、CC#3、CC#4和CC#5。一种场景为,该single DCI可以承载在这5个载波中的任意一个载波上,具体的,承载该single DCI的载波是进行半静态配置的调度的载波中的一个载波,或者,承载该single DCI的载波是进行动态配置的调度的载波中的一个载波,或者,承载该single DCI的载波是5个载波中的除进行半静态配置的调度的载波和进行动态配置的调度的载波之外的一个载波。另一种场景为,该single DCI可以承载在除这5个载波外的其他载波上,例如该single DCI可以承载在CC#6上,可以根据实际使用需求确定。
可选的,在M个载波上进行半静态配置的调度,可以包括以下任意一项:
(1)激活(active)M个载波上的半静态配置。
(2)去激活(inactive)和/或释放(release)M个载波上的半静态配置。
(3)重传(re-transmission)M个载波上的半静态配置。
(4)激活P个载波上的半静态配置,以及,去激活和/或释放Q个载波上的半静态配置。
(5)激活P个载波上的半静态配置,以及,重传Q个载波上的半静态配置。
(6)去激活和/或释放P个载波上的半静态配置,以及,重传Q个载波上的半静态配置。
其中,P和Q均为正整数,且P和Q之和为M。
可选的,在X个载波上进行半静态配置的调度和在Y个载波上进行动态配置的调度,可以包括以下任意一项:
(a)激活X个载波上的半静态配置,以及,初传或重传Y个载波上的动态配置。
(b)去激活和/或释放X个载波上的半静态配置,以及,初传或重传Y个载波上的动态配置。
(c)重传X个载波上的半静态配置,以及,初传或重传Y个载波上的动态配置。
可选的,上述DCI可以包括第一指示域。其中,该第一指示域可以用于指示M个载波,或者,第一指示域可以用于指示X个载波和Y个载波。
可选的,上述第一指示域可以为以下任一项:DCI中的现有域、对DCI中的现有域扩展后得到的域、在DCI中增加的独立域。
在第一指示域为DCI中的现有域的情况下,DCI中不需要专门设置用于指示被调度小区的域。例如,针对上述(1)-(3),现有域是现有DCI中的跨载波指示域(cross-carrier indication field,CIF),高层半静态可以配置一个调度的小区/载波(scheduling CC)和多个被调度的小区/载波(scheduled CCs)。再例如,针对上述(4)-(5)和(a)-(c),高层半静态配置一个调度的小区/载波和多个被调度的小区/载波,如上述表1至表4所示,每个被调度小区的所有特定域(special fields)都独立配置。
在第一指示域为对DCI中的现有域扩展后得到的域的情况下,DCI中需要专门设置用于指示被调度小区的域,且该域是现有DCI中相关域的扩展或增强:例如,扩展CIF和/或带宽部分域(bandwidth part field,BWP field),并重新定义该CIF和BWP的物理含义,如多载波被调度CC的索引值,和/或,多载波被调度CC的索引值以及该CC上BWP的索引值。允许高层可以给多个scheduled CCs配置相同的CIF值,比如高层配置scheduled CC#0、scheduled CC#1的CIF=1,scheduled CC#2、scheduled#3的CIF=2,如果single DCI的CIF=1,那么用于指示调度CC#0和CC#1,而如果single DCI的CIF=2,那么用于指示调度CC#2和CC#3。需要说明的是,若是针对上述(1)-(3)则每个被调度小区的所有special fields无需独立配置;而若是针对上述(4)-(5)和(a)-(c),则每个被调度小区的所有special fields(如上述表1至表4所示)需要独立配置。
在第一指示域为在DCI中增加的独立域的情况下,DCI中需要专门设置用于指示被调度小区的域,且该域可以是新引入的、独立的用来指示哪些被调度的CC的。需要说明的是,本申请实施例对独立域的大小不作具体限定。
可选的,上述DCI可以动态的指示作用于至少一个载波,此时,需要专门指示被调度小区的域。该域可以是在DCI中增加的独立域;或者,该域可以是对DCI中的现有域扩展后得到的域,例如重新赋予CIF field的编码点(codepoint)的含义。以DCI支持调度CC#0、CC#1和CC#2为例,表5为本申请实施例提供的CIF中的编码点的值和被调度CC的对应关系表。
表5
CIF中的编码点的值 描述
00 一个CC(如CC#0)
01 CC#0,CC#1
10 CC#1,CC#2
11 所有CC(CC#0,CC#1,CC#2)
例如,以single DCI用于激活载波上的半静态配置为例。single DCI可以在时刻1、时隙(slot)1、符号(symbol)1、PDCCH监测时机(PDCCH monitoring occasion)1,CIF=00,激活CC#0上的DL SPS或/和UL CG。该single DCI可以在时刻2、时隙(slot)2、符号(symbol)2、PDCCH监测时机(PDCCH monitoring occasion)21,CIF=10,激活CC#0上的DL SPS或/和UL CG。
可选的,上述DCI还可以包括第二指示域。其中,该第二指示域可以用于指示半静态配置或半静态配置的调度方式,该调度方式包括以下至少一项:激活、去激活和重传。
可选的,第二指示域可以为以下任一项:DCI中的现有域(例如HPN域)、对DCI中的现有域扩展后得到的域(例如扩展HPN域)、在DCI中增加的独立域。对于第二指示域的具体实现方式可以参照上述实施例中对第一指示域的相关描述,此处不再赘述。
可选的,第二指示域为一组指示域。或者,第二指示域为多组指示域,该多组指示域的数量与第一指示域指示的进行半静态配置调度的载波数量相同。
针对第二指示域为一组指示域,具体可以包括:
一种可能的实现方式为,若M个载波或X个载波中至少一个载波包括多个半静态配置,且第二指示域为一组指示域,则该第二指示域可以用于指示至少一个半静态配置,该至少一个半静态配置可以为M个载波或X个载波中至少两个载波均包括的半静态配置。
另一种可能的实现方式为,若M个载波或X个载波中每个载波均包括一个相同的半静态配置,且第二指示域为一组指示域,则第二指示域用于指示一个相同的半静态配置的调度方式。
针对第二指示域为多组指示域,具体可以包括:
一种可能的实现方式为,若M个载波或X个载波中一个载波包括多个半静态配置,且第二指示域为多组指示域,则一个第二指示域用于指示至少一个半静态配置,该至少一个半静态配置为该多个半静态配置中的半静态配置。
另一种可能的实现方式为,若M个载波或X个载波中一个载波包括一个半静态配置,且第二指示域为多组指示域,则一个第二指示域用于指示该一个半静态配置的调度方式。
为了更清楚地理解第二指示域为一组指示域或多组指示域,下面以某个CC上配置了一个或多个DL SPS/UL CG为例进行示例性地说明:
i、DCI只作用于该CC上的1个DL SPS或UL CG。
第一种场景为,多个被调度CC共享一个指示DL SPS或UL CG索引的域。该域可以是独立的域或者现有域的扩展,如:HPN域。
当CC上只配置了一个DL SPS或UL CG,HPN域可作为特定域;而当CC上配置了多个DL SPS或UL CG,HPN域用来指示一个DL SPS或UL CG索引,多个CC上相同DL SPS或UL CG索引的配置被激活、去激活或者重传。
表6
HPN中的编码点的值 描述
00 SPS配置#0
01 SPS配置#1
10 SPS配置#2
11 SPS配置#3
如表6所示,当DCI的HPN域中的编码点的值不同时,可以指示不同的DL SPS配置。例如,若HPN中的编码点的值为00,则表示对SPS配置#0进行半静态配置的调度。
第二种场景为,多个被调度CC有各自独立的指示DL SPS或UL CG索引的域。该域可以是独立的域或现有域的扩展,如:HPN域。
当CC上只配置了一个DL SPS或UL CG,HPN域可作为特定域;而当CC上配置了多个DL SPS或UL CG,每个被调度CC的HPN域用来指示该被调度CC的一个DL SPS或UL CG的索引。
ii、DCI作用于该CC上全部或所有的DL SPS或UL CG。指示DL SPS或UL CG索引的域是独立的域或现有域的扩展,如HPN域可以共享或者独立,作为特定域,固定值为全‘0’。
iii、DCI可以动态的指示作用于该CC上的1个或者多个DL SPS或UL CG。
第一种场景为,多个被调度CC共享一个指示DL SPS或UL CG索引的域。该域可以是独立的域或现有域的扩展,如HPN域。HPN域可以用来指示一个或多个DL SPS或UL CG索引的域。如表7-1所示,多个CC上相同DL SPS索引的配置被激活、去激活或者重传;或者,如表7-2所示,多个CC上不同的DL SPS索引的配置被激活、去激活或者重传。
表7-1
Figure PCTCN2021094339-appb-000003
表7-2
Figure PCTCN2021094339-appb-000004
如上述表7-1所示,当DCI的HPN域中的编码点的值不同时,可以指示不同的DL SPS配置。例如,若HPN中的编码点的值为01,则表示对SPS配置#1、SPS配置#2进行调度。再例如,若HPN中的编码点的值为10,则表示对SPS配置#2、SPS配置#3进行调度
如上述表7-2所示,当DCI的HPN域中的编码点的值不同时,可以指示不同的CC上的不同DL SPS配置。例如,若HPN中的编码点的值为01,则表示对CC#0上的SPS配置 #1、CC#1上的SPS配置#2、CC#2上的SPS配置#3进行调度。再例如,若HPN中的编码点的值为10,则表示对CC#1上的SPS配置#2、CC#3上的SPS配置#3进行调度。
需要说明的是,上述表7-1是以对多个CC上相同DL SPS索引的配置被激活、去激活或者重传,上述表7-2是以多个CC上不同DL SPS索引的配置被激活、去激活或者重传为例进行示例性说明的。可以理解的是,对于多个CC上相同UL CG索引的配置被激活、去激活或者重传,或多个CC上不同UL CG索引的配置被激活、去激活或者重传,可以参照表7-1和表7-2中的描述,此处不再赘述。
第二种场景为,多个被调度CC有各自独立的指示DL SPS或UL CG索引的域。该域可以是独立的域或现有域的扩展,如HPN域。每个被调度CC的HPN域只用来指示该被调度CC的一个或多个DL SPS或UL CG索引的域。
可选的,本申请实施例可以对上述DCI加扰。
第一种方式为,若DCI用于指示在M个载波上进行半静态调度,则采用CS-RNTI对该DCI加扰。通常,该DCI可以携带在PDCCH中,因此第一种方式具体可以为采用CS-RNTI对携带该DCI的PDCCH的CRC加扰。
第二种方式为,若DCI用于指示在X个载波上进行半静态调度和在Y个载波上进行动态调度,则采用CS-RNTI、C-RNTI或预定义RNTI对该DCI加扰。通常,该DCI可以携带在PDCCH中,因此第二种方式具体可以为采用CS-RNTI、C-RNTI或预定义RNTI对携带该DCI的PDCCH的CRC加扰。
需要说明的是,上述预定义RNTI与现有的CS-RNTI和C-RNTI均不相同,为新引入或定义的RNTI。当UE检测到该预定义RNTI时,代表single DCI用来在某些高层指定的CC上做动态PDSCH或PUSCH调度,并在其他高层指定的CC上做半静态的DL SPS和/或UL CG的激活、去激活和/或重传。

可选的,在DCI指示的多载波中,可以设置用于指示参数值的参数域,这些参数可以包括DMRS、MCS、NDI、冗余版本(redundancy version,RV)等,可以根据实际使用需求确定,本申请实施例不作限定。另外,这些参数的域是独立的或共享的,具体可以分为下述3种情况:
第1种情况
DCI指示的载波中的每个载波分别对应一组参数指示域,一个载波对应的一组参数指示域中的不同参数指示域用于指示一个载波的不同种传输参数,且不同载波对应不同组参数指示域。在这种情况下,DCI指示的载波的所有的传输参数fields是独立,拥有独立的field,且独立编码。
第2种情况
DCI指示的所有载波对应一组参数指示域,所有载波对应的一组参数指示域中的不同参数指示域用于指示所有载波的不同种传输参数。在这种情况下,DCI指示的载波的所有的传输参数fields都是共享的。
具体分为下述的a)、b)、c)。
a)所有载波对应的一组参数指示域指示的传输参数为:DCI指示的所有载波共享的传输参数。即,所有载波的传输参数都是相同的。
b)所有载波对应的一组参数指示域指示的传输参数为:DCI指示的所有载波独立的传输参数。即,所有载波的传输参数不同,设计联合域(joint field),该联合域的每个code-point对应于高层配置的对于调度的每个CC的参数。
c)所有载波对应的一组参数指示域指示的传输参数为:DCI指示的所有载波关联的传输参数,该关联的传输参数为一个载波的传输参数根据另一个载波的传输参数确定。即,所有载波的传输参数不同,高层配置CC#j(0<j≤N)相对于参照(reference)CC#i,例如,i=0的参数偏移值delta,DCI中的field只指示reference CC#i的参数,其他CC的参数在refernce CC#i的参数的基础上偏移delta。其中,i和j均为正整数。
第3种情况
DCI指示的所有载波中的每个载波分别对应一组第一参数指示域,一个载波对应的一 组第一参数指示域中的不同参数指示域用于指示一个载波的不同种传输参数,且不同载波对应不同组参数指示域;并且,DCI指示的所有载波对应一组第二参数指示域,一组第二参数指示域中的不同参数指示域用于指示所有载波的不同种传输参数。在这种情况下,DCI指示的所有载波中的某些传输参数fields是共享,某些传输参数fields是独立的。
需要说明的是,针对第3种情况,至少下列传输参数fields每个scheduled CC是独立配置的:MCS、NDI、冗余版本(redundancy version,RV)。
通过对MCS、NDI、RV fields的值的设定,可以判断对scheduled CC上DL SPS和/或UL CG的调度方式,例如激活、去激活、重传。
示例性的,假设NDI=0,判定为激活或去激活;假设NDI=1,判定为重传。
当NDI=0时,激活和去激活具体可以由MCS和RV fields决定。例如,若RV=全‘0’,MCS≠全‘1’,判定为激活;若RV=全‘0’,MCS=全‘1’,判定为去激活。
