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,且“第一”、“第二”所区别的对象通常为一类,并不限定对象的个数,例如第一对象可以是一个,也可以是多个。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。
值得指出的是,本申请实施例所描述的技术不限于长期演进型(Long Term Evolution,LTE)/LTE的演进(LTE-Advanced,LTE-A)系统,还可用于其他无线通信系统,诸如码分多址(Code Division Multiple Access,CDMA)、 时分多址(Time Division Multiple Access,TDMA)、频分多址(Frequency Division Multiple Access,FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access,OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access,SC-FDMA)和其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用,所描述的技术既可用于以上提及的系统和无线电技术,也可用于其他系统和无线电技术。然而,以下描述出于示例目的描述了新空口(New Radio,NR)系统,并且在以下大部分描述中使用NR术语,尽管这些技术也可应用于NR系统应用以外的应用,如第6代(6th Generation,6G)通信系统。
图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括终端11和网络侧设备12。其中,终端11也可以称作终端设备或者用户终端(User Equipment,UE),终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant,PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer,UMPC)、移动上网装置(Mobile Internet Device,MID)、可穿戴式设备(Wearable Device)或车载设备(VUE)、行人终端(PUE)等终端侧设备,可穿戴式设备包括:手环、耳机、眼镜等。需要说明的是,在本申请实施例并不限定终端11的具体类型。网络侧设备12可以是基站或核心网,其中,基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station,BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set,BSS)、扩展服务集(Extended Service Set,ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、WLAN接入点、WiFi节点、发送接收点(Transmitting Receiving Point,TRP)或所述领域中其他某个合适的术语,只要达到相同的技术效果,所述基站不限于特定技术词汇,需要说明的是,在本申请实施例中仅以NR系统中的基站为例,但是并不限定基站的具体类型。
下面结合附图,通过具体的实施例及其应用场景对本申请实施例提供的信息确定方法进行详细地说明。
如图2所示,本申请实施例提供一种信息确定方法,应用于终端,包括:
步骤201:接收第一下行控制信息DCI,第一DCI调度多个目标对象;
步骤202:确定第一DCI中至少部分信息指示域的特征信息。
DCI为网络侧设备向终端发送的下行控制信息,在NR系统中,定义了多种DCI format(DCI格式),不同格式的DCI,可分别用于不同的目的,例如,可用于调度数据、资源抢占、通知slot format(slot格式)以及上行功率控制等,其中,slot为时隙。
第一DCI中包括一个或多个信息指示域,信息指示域可以理解为字段,DCI中的不同的信息指示域用于指示不同的信息,对应不同的功能。频域资源分配(Frequency Domain Resource Assignment,FDRA)域为DCI中一个信息指示域,以FDRA域为例,用于指示调度的频域资源,其功能为频域资源分配。
在本实施例中,首先,终端接收网络侧设备发送的第一DCI,接收的第一DCI可调度多个目标对象。接收第一DCI之后,即可确定第一DCI中部分信息指示域的特征信息,实现信息确定。作为一个示例,上述目标对象可以包括载波、小区和带宽部分(Bandwidth Part,BWP)中的至少一项。上述调度目标对象可以理解为调度目标对象上的目标数据,其中,目标数据可以是多个上行数据,或者多个下行数据,或者一部分上行数据和一部分下行数据。
作为一个示例,上述特征信息可以是终端根据协议确定的、终端根据预设规则确定的、是网络侧设备指示的、也可以是承载在终端获取的配置信息中,配置信息包括以下至少一项:ServingCellConfig或PDSCH-Config或PUSCH-Config。需要说明的是,终端获取的配置信息可以是接收网络侧设备发送的配置信息,也可以是协议规定的配置信息,也可以是终端确定的。
本实施例的信息确定方法中,接收第一DCI,第一DCI可调度多个目标对象,然后终端确定第一DCI中至少部分信息指示域的特征信息即可,使得终端可以确定第一DCI中至少部分信息域的特征信息,实现信息确定。由于接收的第一DCI可调度多个目标对象,即一个DCI调度多个目标对象,如此,对于多个目标对象,网络侧设备无需针对每个目标对象发送一次DCI,终端无需针对每个目标对象接收一次DCI,接收可调度多个目标对象的第一DCI即可,从而可减少DCI的传输开销。
可选的,如图3所示,确定第一DCI中至少部分信息指示域的特征信息的步骤202之后,还包括:
步骤203:依据第一DCI中至少部分信息指示域的特征信息,确定多个目标对象的调度信息。
目标对象的调度信息可以理解为用于调度目标对象的调度信息,在本实施例中,是根据至少部分信息指示域的特征信息,确定上述多个目标对象的调度信息,可提高确定的调度信息的准确性。
需要说明的是,信息指示域对应多个子指示域可以理解为:同一个功能下但对应的目标对象可能有不同的信息域(field),或者可以理解为信息指示域包含的多个子信息域,例如信息指示域为频域资源分配,DCI中包含了两个频域资源分配域且针对不同的被调度小区,则信息指示域可以看做DCI中的所有频域资源分配域的整体,两个频域资源分配域分别为两个子指示域;或者可以理解为信息指示域的部分,或者可以理解为信息指示域内的部分比特,例如信息指示域对应10个bit,其中前5个bit为一个子指示域,后5个bit为另一个子指示域。
可选的,至少部分信息指示域的特征信息包括如下至少一项:
至少部分信息指示域中每个信息指示域对应的子指示域的个数;
至少部分信息指示域中每个信息指示域的比特数;
至少部分信息指示域中每个信息指示域对应的子指示域的比特数;
至少部分信息指示域的类型。
其中,信息指示域的比特数为该信息指示域对应的子指示域的比特数总和。至少部分信息指示域的类型可以理解为至少部分信息指示域的整体类型,也可以是至少部分信息指示域中每个信息指示域的类型。
可选的,确定第一DCI中至少部分信息指示域的特征信息,包括以下至少一项:
获取特征指示信息,特征指示信息指示至少部分信息指示域的特征信息;
确定第一DCI中至少部分信息指示域的类型,并根据至少部分信息指示域的类型,确定至少部分信息指示域的子特征信息;
其中,子特征信息包括以下至少一项:
至少部分信息指示域中每个信息指示域对应的子指示域的个数;
至少部分信息指示域中每个信息指示域的比特数;
至少部分信息指示域中每个信息指示域对应的子指示域的比特数。
即在本实施例中,可获取指示至少部分信息指示域的特征信息的特征指示信息,从而确定第一DCI中至少部分信息指示域的特征信息。也可以先确定至少部分信息指示域的类型,然后通过至少部分信息指示域的类型,确定至少部分信息指示域的子特征信息,从而实现少部分信息指示域的特征信息的确定。可提高确定的至少部分信息指示域的特征信息的准确性。
作为一个示例,上述特征指示信息可以是协议规定的、终端根据预设规则获取的、或者是网络侧设备发送的。
可选的,确定第一DCI中至少部分信息指示域的类型,包括:
获取类型指示信息,类型指示信息指示至少部分信息指示域的类型。
可获取指示至少部分信息指示域的类型的类型指示信息,从而确定第一DCI中至少部分信息指示域的类型。
作为一个示例,上述类型指示信息可以是协议规定的、终端根据预设规则获取的、或者是网络侧设备发送的。
例如,终端可接收网络侧设备发送的类型指示信息,类型指示信息可以是无线资源控制(Radio Resource Control,RRC)信令、媒体接入控制-控制单元(Media Access Control-Control Element,MAC-CE)信令或DCI,通过类型指示信息来配置、使能、去使能或修改信息指示域的类型,从而实现信息指示域的类型的确定。
可选的,获取类型指示信息,类型指示信息指示至少部分信息指示域的类型,包括:类型指示信息指示至少部分信息指示域中每个信息指示域的类型。
至少部分信息指示域的数量可以是一个或多个,在本实施例中,获取类型指示信息,该类型指示信息可指示至少部分信息指示域中每个信息指示域的类型,亦即是说,可确定至少部分信息指示域中每个信息指示域的类型,可根据至少部分信息指示域中每个信息指示域的类型确定至少部分信息指示域的子特征信息。
可选的,第一DCI中至少部分信息指示域包括第一类型的第一信息指示域和/或第二类型的第二信息指示域。
对于第一DCI中至少部分信息域的不同类型情况,可确定不同的调度,在本实施例中,至少部分信息指示域的类型可包括第一类型和/或第二类型,后续可基于至少部分信息指示域的第一类型的第一信息指示域和/或第二类型的第二信息指示域确定多个目标对象的调度,从而提高确定的多个目标对象的调度的准确性。
可选的,在第一DCI包括第一信息指示域的情况下,第一信息指示域中任一信息指示域对应的子指示域的个数为N或M,M<N,N为多个目标对象的数量。
M为正整数,N为大于1的整数,在本实施例中,若第一DCI中存在第一类型的第一信息指示域,任一的第一信息指示域对应的子指示域的个数最多为多个目标对象的数量,可避免子指示域的个数过多导致资源浪费的问题。
可选的,第一信息指示域为第一DCI中必选的信息指示域和/或第一信息指示域具有缺省值。
可以理解,第一DCI中必选的信息指示域可被指示为第一类型,第一DCI中具有缺省值的信息指示域也可被指示为第一类型。作为一个示例,第一类型为专用类型。专用类型可以理解是小区或BWP或载波或数据专用,即不同的小区或BWP或载波或数据会有分别对应的指示。
可选的,第一信息指示域中任一信息指示域对应的至少部分子指示域中,每个子指示域对应不同的被调度的目标对象。如此,可减少调度干扰,提高目标对象调度的稳定性。
可选的,在DCI包括第二信息指示域的情况下,第二信息指示域中任一信息指示域对应的子指示域的个数为N或1,N为多个目标对象的数量。
在本实施例中,若第一DCI中存在第二类型的第二信息指示域,任一的第二信息指示域对应的子指示域的个数为多个目标对象的数量或者为1,可避免子指示域的个数过多导致资源浪费的问题。
可选的,第二信息指示域为第一DCI中可选的信息指示域和/或第二信息指示域不具有缺省值。
可以理解,第一DCI中可选的信息指示域可被指示为第二类型,第一DCI中不具有缺省值的信息指示域也可被指示为第二类型。作为一个示例,第二类型为可共享类型。可共享类型可以理解是多个小区或BWP或载波或数据专用可以共享,即不同的小区或BWP或载波或数据会可以对应同一个的指示。
作为一个示例,第二信息指示域还可包括以下至少一项:
信道探测用参考信号资源指示(Sounding Reference Signal resource indicator,SRS resource indicator,SRI);
Beta offset(Beta参数偏移量);
TPC command(发射功率控制命令);
物理上行控制信道(Physical Uplink Control Channel,PUCCH)相关的field(指示域)。
对于PUCCH相关的field,例如PUCCH资源指示信息,又例如混合自动重传请求(Hybrid Automatic Repeat reQuest,HARQ)反馈时延等。
可以理解,第一DCI中上述至少一项的信息指示域可被指示为第二类型。
可选的,至少部分信息指示域的特征信息包括至少部分信息指示域中每个信息指示域对应的子指示域的个数;
在第一DCI包括第一类型的第一信息指示域的情况下,依据确定第一DCI中至少部分信息指示域的特征信息,确定多个目标对象的调度信息,包括:
在第一信息指示域中包括第一目标信息指示域,且第一目标信息指示域的M个子指示域中的至少部分子指示域有对应的第一目标对象的情况下,确定以下至少一项:
第一目标对象按照对应的子指示域被调度;
其他目标对象中的至少部分不支持第一目标信息指示域对应的功能,其中,第一目标信息指示域为第一信息指示域中对应的子指示域的个数为M的信息指示域。
第一目标对象为多个目标对象中第一信息指示域的M个子指示域中的至少部分子指示域对应的目标对象,由于第一类型的第一信息指示域对应的子 指示域的个数可以为M或N,若在第一类型的第一信息指示域中包括第一目标信息指示域,即表示第一信息指示域中包括子指示域的个数为M的信息指示域,则可确定第一目标对象按照对应的子指示域被调度。也可以在第一信息指示域中包括第一目标信息指示域,且第一目标信息指示域的M个子指示域中的至少部分子指示域对应第一目标对象的情况下,确定其他目标对象中的至少部分不支持第一目标信息指示域对应的功能,可以理解,其他目标对象中的至少部分不支持被第一目标信息指示域对应的子指示域调度。例如,非周期信道状态信息(Channel State Information,CSI)报告和/或非周期CSI请求和/或SRS(信道探测用参考信号)和/或非周期SRS和/或非周期测量报告。需要说明的是,该其他目标对象为多个目标对象中除上述第一目标对象之外的对象。另外,每个子指示域都有对应的第一目标对象,即至少部分子指示域有对应的第一目标对象,可以理解为至少部分子指示域中每个子指示域有对应的第一目标对象。
可选的,至少部分信息指示域的特征信息包括至少部分信息指示域中每个信息指示域对应的子指示域的个数;
在第一DCI包括第一类型的第一信息指示域的情况下,依据确定第一DCI中至少部分信息指示域的特征信息,确定多个目标对象的调度信息,包括:

第一目标对象按照对应的子指示域被调度;
其他目标对象中的至少部分支持第一目标信息指示域对应的功能;
其他目标对象中的至少部分按照第一调整后的子指示域被调度;
其中,第一调整后的子指示域为利用第一预设偏移量对第一目标对象对应的子指示域进行调整后的结果,第一目标信息指示域为第一信息指示域中对应的子指示域的个数为M的信息指示域。
即第一目标对象为多个目标对象中第一信息指示域的M个子指示域中的至少部分子指示域对应的目标对象,由于第一类型的第一信息指示域对应的 子指示域的个数可以为M或N,若在第一类型的第一信息指示域中包括第一目标信息指示域,即表示第一信息指示域中包括子指示域的个数为M的信息指示域,在第一信息指示域中包括第一目标信息指示域,且第一目标信息指示域的M个子指示域中的至少部分子指示域有对应的第一目标对象的情况下,可确定第一目标对象按照对应的子指示域被调度。
也可以在第一信息指示域中包括第一目标信息指示域,且第一目标信息指示域的M个子指示域中的至少部分子指示域对应第一目标对象的情况下,确定其他目标对象中的至少部分支持第一目标信息指示域对应的功能,可以理解,其他目标对象中的至少部分支持被第一目标信息指示域对应的子指示域调度。需要说明的是,该其他目标对象为多个目标对象中除上述第一目标对象之外的对象。
另外,也可以在第一信息指示域中包括第一目标信息指示域,且第一目标信息指示域的M个子指示域中的至少部分子指示域对应第一目标对象的情况下,确定其他目标对象中的至少部分按照第一调整后的子指示域被调度。
可选的,利用第一预设偏移量对第一目标对象对应的子指示域进行调整后的结果,可以理解为,利用第一预设偏移量对第一目标对象对应的子指示域进行偏移,得到第一调整后的子指示域,例如,第一目标对象对应的子指示域为1,将其进行加一的偏移(第一预设偏移量为1),则得到的第一调整后的子指示域为2。也可以理解为,利用第一预设偏移量对第一目标对象对应的子指示域所指示的含义进行偏移,实现对第一目标对象对应的子指示域所指示的含义的调整,可以认为是实现对第一目标对象对应的子指示域的调整,从而得到第一调整后的子指示域。例如,第一目标对象对应的子指示域为1,第一目标对象对应的子指示域所指示的含义为X,利用第一预设偏移量,将其进行偏移,则得到的第一调整后的子指示域所指示的含义为对X进行偏移后的结果。
例如,第一DCI调度小区CC1和小区CC2,第一DCI中调制编码(Modulation and Coding Scheme,MCS)信息指示域只携带了一个5bit的MCS指示域且该MCS指示域对应CC1,此时CC2采用相对于CC1的MCS指示域的偏移delta1后的值进行传输,即CC2可使用的MCS=CC1的MCS 指示域+delta1,或者,CC2使用的MCS=CC1的MCS指示域-delta1。可选地,可以通过RRC、MAC-CE或DCI配置CC2的MCS指示域相对于CC1的MCS指示域的delta1值。
可选的,至少部分信息指示域的特征信息包括至少部分信息指示域中每个信息指示域对应的子指示域的个数;
在第一DCI包括第二类型的第二信息指示域的情况下,依据确定第一DCI中至少部分信息指示域的特征信息,确定多个目标对象的调度信息,包括:
在第二信息指示域中包括第二目标信息指示域,且第二目标信息指示域的子指示域有对应的第二目标对象的情况下,确定以下至少一项:
第二目标对象按照对应的子指示域被调度;
其他目标对象中的至少部分支持第二目标信息指示域对应的功能;
其他目标对象的至少部分按照第二目标对象中的至少部分对应的子指示域被调度和其他目标对象中的至少部分按照第二调整后的子指示域被调度中的一项;
其中,第二调整后的指示域为利用第二预设偏移量对第二目标对象对应的子指示域进行调整后的结果,第二目标信息指示域为第二信息指示域中对应的子指示域的个数为1的信息指示域。
第二目标对象为多个目标对象中第二信息指示域的子指示域对应的目标对象,由于第二类型的第二信息指示域对应的子指示域的个数可以为1或N,若在第二类型的第二信息指示域中包括第二目标信息指示域,即表示第二信息指示域中包括子指示域的个数为1的信息指示域,则可确定第二目标对象按照对应的子指示域被调度。
也可以在第二信息指示域中包括第二目标信息指示域,且第二目标信息指示域的子指示域对应第二目标对象的情况下,确定其他目标对象中的至少部分支持第二目标信息指示域对应的功能,可以理解,其他目标对象中的至少部分支持被第二目标信息指示域对应的子指示域调度。需要说明的是,此处的其他目标对象为多个目标对象中除上述第二目标对象之外的对象。
也可以在第二信息指示域中包括第二目标信息指示域,且第二目标信息 指示域的子指示域对应第二目标对象的情况下,确定其他目标对象中的至少部分按照第二目标对象中的至少部分对应的子指示域被调度或确定其他目标对象中的至少部分按照第二调整后的子指示域被调度。可以理解,其他目标对象中的至少部分支持被第二目标信息指示域中至少部分对应的子指示域调度。需要说明的是,此处的其他目标对象为多个目标对象中除上述第二目标对象之外的对象。
例如,第一DCI中的频域资源分配域中只有一个指示域,且这个指示域对应CC11,且指示域指示调度小区CC1的BWP上的RB#1-10,则小区CC2的BWP上的RB#1-10也被调度。
可选的,利用第二预设偏移量对第二目标对象对应的子指示域进行调整后的结果,可以理解为,利用第二预设偏移量对第二目标对象对应的子指示域进行偏移,得到第二调整后的子指示域,例如,第二目标对象对应的子指示域为1,将其进行加一的偏移(第二预设偏移量为1),则得到的第二调整后的子指示域为2。也可以理解为,利用第二预设偏移量对第二目标对象对应的子指示域所指示的含义进行偏移,实现对第二目标对象对应的子指示域所指示的含义的调整,可以认为是实现对第二目标对象对应的子指示域的调整,从而得到第二调整后的子指示域。例如,第二目标对象对应的子指示域为1,利用第二预设偏移量,第二目标对象对应的子指示域所指示的含义为Y,将其进行偏移,则得到的第二调整后的子指示域所指示的含义为对Y进行偏移后的结果。
例如,第一DCI调度小区CC1和小区CC2,第一DCI中某个信息指示域中只有一个5bit的子指示域且对应CC1,此时CC2采用相对于CC1的MCS指示域的偏移后delta2的值进行传输,即CC2使用的MCS=CC1的MCS指示域+delta2,或者,CC2使用的MCS=CC1的MCS指示域-delta2。可选的,可以通过RRC、MAC-CE或DCI配置CC2的该子指示域相对于CC1的该子指示域的delta2值。
可选的,确定至少部分信息指示域的特征信息,包括:
根据调度小区的第一配置信息,确定至少部分信息指示域的特征信息。
即接收第一DCI后,即可根据第一DCI对应的调度小区的第一配置信 息,分别确定至少部分信息指示域的特征信息。
可选的,确定至少部分信息指示域的特征信息,包括:根据调度小区的第一配置信息,确定至少部分信息指示域对应的子指示域中第一目标子指示域的个数和/或比特数,第一目标子指示域为与被调度小区对应的子指示域。
接收第一DCI后,即可根据第一DCI对应的调度小区的第一配置信息,分别确定至少部分信息指示域对应的子指示域中第一目标子指示域的个数和/或比特数。作为一个示例,可根据至少部分信息指示域对应的调度小区的第一配置信息,确定至少部分信息指示域对应的子指示域中第一目标子指示域的个数和/或比特数。作为一个示例,调度小区的第一配置信息包括每个被调度小区的第二配置信息。其中,第一配置信息可以包括ServingCellConfig或BWP-DownlinkDedicated,第二配置信息可以包括PDSCH-Config和/或PUSCH-Config。
例如,调度小区的中ServingCellConfig或BWP-DownlinkDedicated包含了每个被调度小区的PDSCH-Config,根据这些PDSCH-Config可分别确定第一DCI中至少部分信息指示域对应的子指示域中和每个被调度小区对应的子指示域的比特数和/或个数。
又例如,调度小区的中ServingCellConfig或BWP-DownlinkDedicated包含了每个被调度小区的PUSCH-Config,根据这些PDSCH-Config可分别确定至少部分信息指示域对应的子指示域中和每个被调度小区对应的子指示域的比特数和/或个数。
又例如,假设CC1上的第一DCI调度CC1和CC2,则CC1的BWP-DownlinkDedicated包含了CC1和CC2的PDSCH-Config,分别为PDSCH-Config-CC1和PDSCH-Config-CC2。其中,BWP-DownlinkDedicated如下所示:
Figure PCTCN2021110515-appb-000001
Figure PCTCN2021110515-appb-000002
如此,根据BWP-DownlinkDedicated中的PDSCHConfig-CC1可确定第一DCI中至少部分信息指示域对应的子指示域中和CC1对应的子指示域的比特数和/或个数。根据BWP-DownlinkDedicated中的PDSCHConfig-CC2可确定第一DCI中至少部分信息指示域对应的子指示域中和CC2对应的子指示域的比特数和/或个数。

对于至少部分信息指示域,根据至少部分信息指示域对应的被调度小区的第二配置信息,确定多个目标对象的调度。作为一个示例,第二配置信息可以包括PDSCH-Config和/或PUSCH-Config。
例如,分别根据每个被调度小区的ServingCell-Config或BWP-DownlinkDedicated中的PDSCH-Config,确定第一DCI中至少部分信息指示域对应的子指示域中和每个被调度小区对应的子指示域的比特数和/或个数。
例如分别根据每个被调度小区的ServingCell-Config或BWP-DownlinkDedicated中的PUSCH-Config,确定至少部分信息指示域对应的子指示域中和每个被调度小区对应的子指示域的比特数和/或个数。
可选的,在第一DCI中第三目标信息指示域对应一个子指示域的情况下,第一DCI调度一个目标对象;其中,第三目标信息指示域为预设第一类型的信息指示域。
即第一DCI中预设第一类型的信息指示域对应的子指示域只有一个(假 设对应CC1)的情况下,第一DCI只能调度一个目标对象。
作为一个示例,第一类型的信息指示域即第一信息指示域,预设第一类型的信息指示域可以是第一类型的信息指示域中的某个信息指示域、某些特定的信息指示域、预设数目个信息指示域或全部信息指示域。
可选的,在第一DCI调度一个目标对象的情况下,若第一DCI中包括第二信息指示域,且第二信息指示域中包括对应多个子指示域的第四目标信息指示域,则第四目标信息指示域对应的多个子指示域中的第二目标子指示域有效。
若第一DCI中包括对应多个子指示域的第四目标信息指示域且第四目标信息指示域为第二类型,则对于第四目标信息指示域的多个子指示域,只有某个子指示域(第二目标子指示域)有效。作为一个示例,第二目标子指示域与第一DCI调度的一个目标对象对应。
可选的,在第一DCI中第五目标信息指示域对应一个子指示域的情况下,第一DCI调度一个目标对象;其中,第五目标信息指示域为预设第二类型的信息指示域。

作为一个示例,第二类型的信息指示域即第二信息指示域,预设第二类型的信息指示域可以是第二类型的信息指示域中的某个信息指示域、某些特定的信息指示域、预设数目个信息指示域或全部信息指示域。
可选的,在第一DCI调度一个目标对象的情况下,若第一DCI中包括第一信息指示域,且第一信息指示域中包括对应多个子指示域的第六目标信息指示域,则第六目标信息指示域对应的多个子指示域中的第三目标子指示域有效。
若第一DCI中包括对应多个子指示域的第六目标信息指示域且第六目标信息指示域为第一类型,则对于第六目标信息指示域的多个子指示域,只有某个子指示域(第三目标子指示域)有效。作为一个示例,第三目标子指示域与第一DCI调度的一个目标对象对应。
可选的,在第一DCI中至少部分信息指示域中预设信息指示域对应一个 子指示域的情况下,第一DCI调度一个目标对象。
即只要至少部分信息指示域中预设信息指示域对应的子指示域只有一个,可确定第一DCI只可调度一个目标对象。
作为一个示例,预设信息指示域可以是第一DCI的信息指示域中的某个信息指示域、某些特定的信息指示域、预设数目个信息指示域或全部信息指示域,即预设信息指示域中的信息指示域的类型可以是第一类型和/或第二类型。
