S210,终端设备接收网络设备发送的第一DCI。
可选地,该第一DCI用于调度URLLC业务。
S220,该终端设备根据该第一DCI的DCI格式和配置信息解析该第一DCI,其中,该配置信息对应于DCI格式。
可选地,该配置信息包括时域资源指示信息、CSI报告集合、频域资源指示类型、频域资源指示颗粒度中的至少一种。
可选地,时域资源指示信息可以是时域资源指示表格。
具体地,该终端设备根据该第一DCI的DCI格式(DCI format)和该配置信息解析该第一DCI所调度传输的数据的时域资源和/或频域资源和/或CSI报告。
可选地,该DCI格式包括压缩DCI格式和/或常规DCI格式。
应理解,压缩DCI format的DCI主要用于URLLC业务调度,其所占用的比特数较少,常规DCI format的DCI主要用于常规业务调度(例如,增强移动宽带(Enhance Mobile Broadband,eMBB)业务),其所占用的比特数较多,调度的灵活性大。
在一种实现方式中,如果该配置信息包括时域资源指示信息,该终端设备可以根据该配置信息,以及该第一DCI中时域资源指示域的取值,确定该第一DCI所调度传输的数据的时域资源位置。
具体地,该配置信息包括第一时域资源指示信息和第二时域资源指示信息,其中,该第一时域资源指示信息对应压缩DCI格式,该第二时域资源指示信息对应常规DCI格式。
例如,该配置信息包括时域资源指示信息a和时域资源指示信息b,其中,该时域资源指示信息a对应压缩DCI格式,该时域资源指示信息b对应常规DCI格式。
若该第一DCI的DCI格式属于该压缩DCI格式,该终端设备根据该第一DCI中时域资源指示域的取值和该时域资源指示信息a确定该第一DCI所调度传输的数据的时域资源位置。
若该第一DCI的DCI格式属于该常规DCI格式,该终端设备根据该第一DCI中时域资源指示域的取值和该时域资源指示信息b确定该第一DCI所调度传输的数据的时域资源位置。
可选地,该第一时域资源指示信息指示的时域资源仅包括该第一DCI所在的子帧,或者,仅包括该第一DCI所在的子帧和该第一DCI所在的子帧的下一个子帧;或者
该第一时域资源指示信息指示的时域资源配置数目小于该第二时域资源指示信息指示的时域资源配置数目。
可选地,该第一时域资源指示信息和/或该第二时域资源指示信息中DCI中时域资源指示域的取值可以对应时域资源的起始符号、时长和数据信道类型(例如,类型A(Type A),类型B(Type B))。
例如,该第一时域资源指示信息可以如表1所示,该第二时域资源指示信息可以如表2所示。
表1
DCI中时域资源指示域的取值 起始符号 时长 数据信道类型
1 0 2 Type B

表2
DCI中时域资源指示域的取值 起始符号 时长 数据信道类型
1 0 7 Type A
2 14 7 Type B
3 21 14 Type A
4 28 14 Type B
5 35 14 Type A
因此,可以灵活和有效地进行时域资源指示,避免特定场景(例如URLLC调度)下出现冗余配置(跨子帧调度,大颗粒的调度),或者避免仅有少量的适合URLLC的时域资源配置,从而,能够减少物理层信令开销,提高信令可靠性。
在一种实现方式中,如果该配置信息包括CSI报告集合(CSI report集合),该终端设备可以根据该配置信息,以及该第一DCI中CSI报告指示域的取值,确定该第一DCI所调度传输的数据的CSI报告。
具体地,该配置信息包括第一CSI报告集合和第二CSI报告集合,其中,该第一CSI报告集合对应压缩DCI格式,该第二CSI报告集合对应常规DCI格式。
例如,该配置信息包括CSI报告集合a和CSI报告集合b,其中,该CSI报告集合a对应压缩DCI格式,该CSI报告集合b对应常规DCI格式。
若该第一DCI的DCI格式属于该压缩DCI格式,该终端设备根据该第一DCI中CSI报告指示域的取值和该CSI报告集合a确定该第一DCI所调度传输的数据的CSI报告。
若该第一DCI的DCI格式属于该常规DCI格式,该终端设备根据该第一DCI中CSI报告指示域的取值和该CSI报告集合b确定该第一DCI所调度传输的数据的CSI报告。
可选地,所述第一CSI报告集合包括非周期CSI报告;或者

该第二CSI报告集合包括半静态触发的周期性CSI报告,或者,
该第二CSI报告集合所包括的CSI报告的触发信令所占的比特数大于该第一CSI报告集合所包括的CSI报告的触发信令所占的比特数。
可选地,该第一CSI报告集合和/或该第二CSI报告集合中CSI报告指示域的取值可以对应CSI报告(CSI report)。
可选地,CSI report可以是非周期性CSI(Aperiodic CSI,A-CSI)和周期性CSI(Periodic CSI,P-CSI),CSI可以包括秩指示(Rank Indication,RI)、和信道质量指示(Channel Quality Indicator,CQI)。
例如,该第一CSI报告集合可以如表3所示,在CSI报告指示域的取值为1时,在接收到该第一DCI到上报A-CSI之间间隔2个符号(2symbols);在CSI报告指示域的取值为2时,在接收到该第一DCI到上报A-CSI之间间隔4symbols。该第二CSI报告集合可以如表4所示,在CSI报告指示域的取值为1时,在接收到该第一DCI到上报A-CSI之间间隔2symbols;在CSI报告指示域的取值为2时,在接收到该第一DCI到上报A-CSI之间间隔14symbols;在CSI报告指示域的取值为3时,在接收到该第一DCI到上报A-CSI之间间隔14symbols;在CSI报告指示域的取值为4时,在接收到该第一DCI到上报P-CSI之间间隔2symbols;在CSI报告指示域的取值为5时,在接收到该第一DCI到上报P-CSI之间间隔14symbols。
表3
CSI报告指示域的取值 CSI report

2 A-CSI(CQI)4symbols
表4
CSI报告指示域的取值 CSI report
1 A-CSI(CQI)2symbols
2 A-CSI(CQI)14symbols
3 A-CSI(CQI,RI)14symbols
4 P-CSI 2symbols
5 P-CSI 14symbols
因此,可以优化CSI report集合,从而,减少信令开销。
在一种实现方式中,如果该配置信息包括频域资源指示颗粒度,该终端设备可以根据该配置信息,以及该第一DCI的域值,确定该第一DCI所调度传输的数据的频域资源。
具体地,该配置信息包括第一频域资源指示颗粒度和第二频域资源指示颗粒度,其中,该第一频域资源指示颗粒度对应压缩DCI格式,该第二频域资源指示颗粒度对应常规DCI格式。
例如,该配置信息包括频域资源指示颗粒度a和频域资源指示颗粒度b,其中,该频域资源指示颗粒度a对应压缩DCI格式,该频域资源指示颗粒度b对应常规DCI格式。
若该第一DCI的DCI格式属于该压缩DCI格式,该终端设备根据该第一DCI的域值和该频域资源指示颗粒度a确定该第一DCI所调度传输的数据的频域资源。
若该第一DCI的DCI格式属于该常规DCI格式,该终端设备根据该第一DCI的域值和该频域资源指示颗粒度b确定该第一DCI所调度传输的数据的频域资源。
可选地,该第一频域资源指示颗粒度指示的频域颗粒度大于该第二频域资源指示颗粒度指示的频域颗粒度。
可选地,该第一频域资源指示颗粒度和/或该第二频域资源指示颗粒度可以用资源块组(Resource Block Group,RBG)大小(Size)来表征。RBG Size可以用于(带宽(Band Width,BW),单元(unit):物理资源块(physical resource block,PRB))来表示。
