具体实施方式
下面将结合附图,对本申请实施例中的技术方案进行描述。
本申请实施例的技术方案可以应用于各种通信系统,例如:全球移动通讯(Global System of Mobile Communication,GSM)系统、码分多址(Code Division Multiple Access,CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)系统、长期演进(Long Term Evolution,LTE)系统、LTE频分双工(Frequency Division Duplex,FDD)系统、LTE时分双工(Time Division Duplex,TDD)系统、先进的长期演进(Advanced long term evolution,LTE-A)系统、新无线(New Radio,NR)系统、NR系统的演进系统、非授权频谱上的LTE(LTE-based access to unlicensed spectrum,LTE-U)系统、非授权频谱上的NR(NR-based access to unlicensed spectrum,NR-U)系统、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)、无线局域网(Wireless Local Area Networks,WLAN)、无线保真(Wireless Fidelity,WiFi)、未来的5G系统或其他通信系统等。
通常来说,传统的通信系统支持的连接数有限,也易于实现,然而,随着通信技术的发展,移动通信系统将不仅支持传统的通信,还将支持例如设备到设备(Device to Device,D2D)通信、机器到机器(Machine to Machine,M2M)通信、机器类型通信(Machine Type Communication,MTC)、以及车辆间(Vehicle to Vehicle,V2V)通信等,本申请实施例也可以应用于这些通信系统。
可选地,本申请实施例中的通信系统可以应用于载波聚合(Carrier Aggregation,CA)场景、双连接(Dual Connectivity,DC)场景、独立(Standalone,SA)布网场景等。
示例性的,本申请实施例应用的通信系统100如图1所示。该通信系统100可以包括网络设备110,网络设备110可以是与终端设备120(或称为通信终端、终端)通信的设备。网络设备110可以为特定的地理区域提供通信覆盖,并且可以与位于该覆盖区域内的终端设备进行通信。

在NR系统中引入了基于多个TRP的下行和上行的非相干传输。其中,TRP之间的回传(backhaul)连接可以是理想的或者非理想的。理想的backhaul下TRP之间可以快速动态的进行信息交互,非理想的backhaul下由于时延较大TRP之间只能准静态的进行信息交互。
在下行非相干传输中,多个TRP可以采用不同的控制信道独立调度一个终端设备的物理下行共享信道(Physical Downlink Shared Channel,PDSCH)传输,所调度的PDSCH可以在相同时隙或不同时隙中传输。终端设备需要支持同时接收来自不同TRP的物理下行控制信道(Physical Downlink Control Channel,PDCCH)和PDSCH。终端设备反馈确认/否定确认(Acknowledgement/Negative,ACK/NACK)时,如图2(a)所示,可以将ACK/NACK各自反馈给传输相应PDSCH的不同TRP,如图2(b)所示,也可以合并上报给一个TRP。前者可以应用于理想backhaul和非理想backhaul两种场景,后者只能用于理想backhaul的场景。其中,不同TRP传输的用于调度PDSCH的DCI可以通过不同的控制资源集(Control Resource Set,CORESET)来承载,即网络侧配置多个CORESET,每个TRP采用各自的CORESET进行调度,即可以通过CORESET来区分不同的TRP。
类似地,在上行非相干传输中,不同TRP也可以独立调度同一个终端设备的物理上行共享信道(Physical Uplink Shared Channel,PUSCH)传输。不同PUSCH传输可以配置独 立的传输参数,例如波束、预编码矩阵、层数等。所调度的PUSCH传输可以在相同时隙或不同时隙内传输。如果终端设备在同一个时隙被同时调度了两个PUSCH传输,则需要根据自身能力确定如何进行传输。如果终端设备配置有多个天线面板(panel),且支持在多个panel上同时传输PUSCH,则可以同时传输这两个PUSCH,且不同panel上传输的PUSCH对准相应的TRP进行模拟赋形,从而通过空间域区分不同的PUSCH,提供上行的频谱效率,如图3(a)所示。如果终端设备只有单个panel,或者不支持多个panel同时传输,则只能在一个panel上传输PUSCH,如图3(b)所示。其中,不同TRP传输的用于调度PUSCH的下行控制信息(Download Control Information,DCI)可以通过不同的CORESET来承载,即网络侧配置多个CORESET,每个TRP采用各自的CORESET进行调度。
终端设备可以有多个天线面板(Panel)用于上行传输,一个panel包括一组物理天线,每个panel有独立的射频通道。终端设备需要在能力上报中通知网络侧所配置的天线面板的数量。同时,终端设备还可能需要通知网络侧是否具备在多个天线面板上同时传输信号的能力。由于不同panel对应的信道条件是不同的,不同的panel需要根据各自的信道信息采用不同的传输参数。为了得到这些传输参数,需要为不同的panel配置不同的SRS资源来获得上行信道信息。例如,为了进行上行的波束管理,可以为每个panel配置一个SRS资源集合,从而每个panel分别进行波束管理,确定独立的模拟波束。如图4(a)所示,为了得到PUSCH传输所用的预编码信息,也可以为每个panel配置一个SRS资源集合,用于得到该panel上传输的PUSCH所用的波束、预编码向量、传输层数等传输参数。同时,如图4(b)所示,多panel传输也可以应用于PUCCH,即同一个ACK/NACK反馈资源或者同样时域资源上的ACK/NACK反馈资源携带的信息可以同时通过不同的panel发送给网络侧。
终端设备反馈CSI时,需要分别反馈每个TRP各自对应的CSI。其中,CSI中包括的内容例如可以有秩指示(Rank Indication,RI)、预编码矩阵指示(Precoding Matrix Indicator,PMI)、信道质量指示(Channel Quality Indicator,CQI)等内容,可以用于每个TRP进行下行传输的调度。由于终端设备无法确定CSI是哪个TRP对应的CSI,在CSI和其他上行信道例如CSI、ACK/NACK、PUSCH等上行信道之间发生资源冲突时,也无法确定CSI与发生冲突的信道是否对应于同一个TRP,终端设备就无法采用合适的冲突解决方式,因此,这种情况下终端设备无法有效地进行CSI的上报。
本申请实施例提出一种CSI上报的方法,将CSI与CORESET组索引相关联,通过CORESET组索引区分不同TRP对应的CSI,从而能够有效地进行CSI的上报,使得每个TRP获取各自对应的CSI。并且在CSI和其他上行信道之间发生资源冲突时,终端设备能够采用合适的冲突解决方式,从而实现CSI和其他上行信道的有效传输。
此外,在NR系统中,终端设备可以采用模拟波束来传输上行数据和上行控制信息。终端设备可以基于探测参考信号(Sounding Reference Signal,SRS)信号来进行上行波束管理,从而确定上行传输所使用的模拟波束。如图5所示的上行波束管理的过程,网络侧可以给终端设备配置SRS资源集合1,SRS资源集合1中包括N个SRS资源(N>1)。终端设备可以采用不同的波束发送这N个SRS资源,网络侧分别对N个SRS资源进行接收质量的测量,选择其中接收质量最好的K个SRS资源。网络侧可以再配置一个SRS资源 集合2,SRS资源集合2中包括K个SRS资源,可以指示终端采用SRS资源集合1中选择出来的K个SRS资源所使用的模拟波束来传输SRS资源集合2中的SRS资源。这可以通过将SRS资源集合1中选择出的K个SRS资源分别配置为SRS资源集合2中的K个SRS资源的参考SRS资源来实现。此时,基于终端设备在SRS资源集合2中传输的SRS,网络侧可以选择出接收质量最好的一个SRS资源,并将对应的上行调度请求指示(Schduling Request Indication,SRI)通知给终端。终端设备接收到SRI后,将SRI指示的SRS资源所使用的模拟波束确定为传输PUSCH应使用的模拟波束。对于PUSCH,该SRI可以通过DCI中的SRI指示域来指示。
对于物理上行控制信道(Physical Uplink Control Channel,PUCCH),也可以采用类似的方法来指示所用的波束。具体的,对于每个PUCCH资源,在无线资源控制(Radio Resourse Control,RRC)信令中配置多个PUCCH空间关系信息(PUCCH-spatialrelationinfo),再通过介质访问控制(Medium Access Control,MAC)层信令从中指示当前所用的PUCCH-spatialrelationinfo。其中,每个PUCCH-spatialrelationinfo中包括一个用于确定PUCCH的发送波束的参考信号。对于每个SRS资源,也可以通过RRC信令配置对应的SRS空间关系信息(SRS-spatialrelationinfo),其中包括一个用于确定SRS的发送波束的参考信号。
下面结合图6,详细地描述本申请实施例的上报CSI的方法。
图6是本申请实施例的上报CSI的方法的示意性流程图。其中,该方法600可以由终端设备执行,该终端设备例如可以是图1中所示的终端设备120。该方法600可以包括以下部分或全部内容:
在610中,终端设备获取第一CSI关联的CORESET组索引。
在620中,终端设备根据该第一CSI关联的CORESET组索引,对该第一CSI进行处理。
可选地,在610中,终端设备获取所述第一CSI关联的CORESET组索引,包括:终端设备接收该第一CSI的配置信息,该第一CSI的配置信息中包括该第一CSI关联的CORESET组索引。
该CORESET组索引可以是网络设备通过高层信令配置的。
例如,在第一CSI对应的CSI配置信息中包括CORESET组索引的参数,用于指示CSI配置和第一CSI关联的CORESET组索引,该CSI配置信息例如可以通过RRC参数CSI上报配置(CSI-Report-config)得到。
一种可能的实现方式中,终端设备通过第一CSI的CSI配置信息获得第一CSI关联的索引,且第一CSI关联的索引可以不需要与CORESET或CORESET组关联,即该第一CSI索引用于终端设备确定如何对该第一CSI进行处理,不需要从CORESET获得或者与CORESET绑定。此时,该索引也可以称为CSI索引或者CSI进程索引等。
另一种可能的实现方式中,该索引也可以重用网络设备通过高层信令为不同CORESET配置的CORESET组索引。例如,为第一CSI配置的CORESET组索引可以与网络设备为CORESET配置的CORESET组索引采用相同的参数定义和独立的取值。网络设备可以通过高层信令为不同CORESET配置相应的CORESET组索引。例如,在用于配置CORESET的RRC配置参数例如RRC参数控制资源设置(ControlResourceSet)中,为 每个CORESET分别配置一个索引,本申请实施例中暂将其称为CORESET组索引。
网络设备可以配置多个CORESET,不同TRP采用各自对应的CORESET对终端设备进行调度,因此通过CORESET可以区分不同的TRP。该实施例中,将CSI与CORESET组索引相关联,通过CORESET组索引区分不同TRP对应的CSI,可以实现CSI的有效上报。
例如,终端设备在确定需要上报该第一CSI时,可以将该第一CSI上报给相应的TRP。该第一CSI关联的CORESET组索引可以与该TRP使用的用于调度该终端设备的CORESET的CORESET组索引采用相同的取值。
网络设备为不同CORESET配置的CORESET组索引可以相同,也可以不同。例如,该CORESET组索引的取值为0或1,可以通过1比特的信令来进行指示。可选地,配置相同索引的CORESET可以称为一个CORESET组。
再一种可能的实现方式中,第一CSI关联的CORESET组索引与网络设备为各个CORESET配置的CORESET组索引可以是两套独立的参数。这两套独立的CORESET组索引的值可以独立配置。
也就是说,本申请实施例中,与第一CSI关联的索引可以是与CORESET无关的另一套索引,也可以是复用TRP使用的CORESET的CORESET组索引,还可以是与TRP使用的CORESET的CORESET组索引相对独立的另外一套CORESET组索引,这里均不作限定。网络设备为不同CSI配置其关联的索引时,各个CSI关联的索引能够区分各个CSI对应的TRP即可。
第一CSI可以是周期性的CSI、准持续性的CSI或者非周期性的CSI,本申请对此不做限定。
当第一CSI为非周期性传输的CSI时,可选地,第一CSI关联的CORESET组索引可以是触发该第一CSI上报的DCI所在的CORESET的CORESET组索引(此时,第一CSI关联的索引复用网络设备为CORESET配置的CORESET组索引)。或者,第一CSI关联的CORESET组索引可以与触发该第一CSI上报的DCI所在的CORESET的CORESET组索引采用相同的取值(此时,第一CSI关联的索引与该DCI所在的CORESET的CORESET组索引是独立配置的两套CORESET索引)。即,调度第一CSI上报的TRP与该第一CSI对应的TRP应该是同一个TRP。
在620中,对该第一CSI进行处理包括两方面的处理,一方面是在第一CSI与其他上行信道之间发生资源冲突时的对该CSI的处理,另一方面是确定待上报的该第一CSI的内容。下面分别结合图7和图8对这两方面的处理进行描述。
图7是图6所示的方法的一种可能的实现方式。其中,620可以包括621。如图7所示,该方法包括:
在610中,终端设备获取第一CSI关联的CORESET组索引。
在621中,终端设备在传输第一CSI的时域资源单元与传输其他上行信道的时域资源单元冲突时,根据第一CSI关联的CORESET组索引,对第一CSI进行处理。
例如,在传输第一CSI的时域资源单元与传输其他上行信道的时域资源单元冲突时,终端设备根据该第一CSI关联的CORESET组索引,上报或者丢弃该第一CSI,或者对第一CSI和该上行信道进行复用后传输。
终端设备根据网络设备的调度或者根据接收到的配置信息,确定传输该第一CSI的时域资源单元,以及传输其他上行信道的时域资源单元。如果第一CSI与该上行信道在相同的时域资源单元中传输,则认为发生了资源冲突,需要根据一定的处理方式确定如何进行信号传输。
该时域资源单元可以是时隙、迷你时隙、或者正交频分多路复用(Orthogonal Frequency Division Multiplexing,OFDM)符号等。其中,一个迷你时隙由同一个时隙内的多个OFDM符号组成。
例如,该时域资源单元为OFDM符号,如果第一CSI与该上行信道均在该符号内传输,则认为发生了资源冲突。
又例如,该时域资源单元为时隙时,如果第一CSI与该上行信道均在该时隙内传输,则无论该第一CSI与该上行信道可以在该时隙内的不同符号或相同符号上传输,都认为发生了资源冲突。
当传输第一CSI的时域资源单元与传输其他上行信道的时域资源单元冲突时,可以采用以下几种方式进行冲突解决。
方式1
若第一CSI关联的CORESET组索引与该上行信道关联的CORESET组索引相同,终端设备将第一CSI与该上行信道进行复用传输。
该上行信道关联的CORESET组索引可以是事先约定或者网络设备配置的。例如,如果该上行信道是PUSCH,则其关联的CORESET组索引可以是调度该PUSCH的DCI所在的CORESET的CORESET组索引;如果该上行信道是承载HARQ-ACK信息的PUCCH,则其关联的CORESET组索引可以是调度该HARQ-ACK对应的PDSCH的DCI所在的CORESET的CORESET组索引;如果该上行信道是承载另一个CSI的PUCCH或PUSCH,则可以采用前述确定第一CSI的关联的CORESET组索引的方法,确定另一个CSI关联的CORESET组索引。
该实施例中,传输第一CSI的时域资源单元与传输其他上行信道的时域资源单元冲突时,若第一CSI关联的CORESET组索引与该上行信道关联的CORESET组索引相同,终端设备将第一CSI与该上行信道进行复用后传输。这样,在第一CSI与该上行信道对应于同一个TRP时,通过信号的复用可以避免这些信号被丢弃,从而提升设备的数据传输性能。
例如,终端设备可以将第一CSI与该上行信道携带的信息进行级联后,在同一个PUCCH或同一个PUSCH中传输。其中,第一CSI与该上行信道携带的信息可以独立进行编码。该同一个PUCCH或同一个PUSCH可以是该上行信道。
又例如,终端设备将第一CSI与该上行信道携带的信息进行联合编码后,在同一个PUCCH或同一个PUSCH中传输。其中,该同一个PUCCH或同一个PUSCH可以是该上行信道。
方式2
若第一CSI关联的CORESET组索引与该上行信道关联的CORESET组索引不同,终端设备在第一CSI的优先级高于该上行信道的优先级时,在该时域资源单元上发送所述第一CSI,或者在第一CSI的优先级低于该上行信道的优先级时丢弃第一CSI。
该实施例中,传输第一CSI的时域资源单元与传输其他上行信道的时域资源单元冲突 时,若第一CSI关联的CORESET组索引与该上行信道关联的CORESET组索引不同,终端设备根据第一CSI和该上行信道的优先级信息,确定丢弃第一CSI还是丢弃该上行信道,或者说确定在冲突的该时域资源单元上传输第一CSI还是传输该上行信道。从而在第一CSI与该上行信道对应于不同的TRP时,保障优先级高的信号的传输。
该优先级信息可以由终端设备和网络设备预先约定,例如协议中规定;该优先级信息也可以是网络设备配置的。
该优先级信息例如可以包括以下中的至少一种:
1)该上行信道为携带混合自动重传请求确认HARQ-ACK信息的物理上行控制信道PUCCH时,第一CSI的优先级低于该PUCCH的优先级。
2)该上行信道为承载有数据的物理上行控制信道PUSCH时,第一CSI和该PUSCH的优先级是根据第一CSI关联的CORESET组索引和该上行信道关联的CORESET组索引确定的。
例如,CORESET组索引的值越低,对应的信号的优先级越高,因此丢弃这第一CSI和该上行信道中关联的CORESET组索引较大的那一个。
3)该上行信道为携带第二CSI的PUCCH或PUSCH时,第一CSI和该上行信道的优先级是根据第一CSI关联的CORESET组索引和所述上行信道关联的CORESET组索引确定的。
例如,CORESET组索引的值越低,对应的信号的优先级越高,因此丢弃这第一CSI和该上行信道中关联的CORESET组索引较大的那一个。
方式3
若所述第一CSI关联的CORESET组索引与该上行信道关联的CORESET组索引不同,终端设备在约定传输第一CSI时在所述时域资源单元上报第一CSI,或者在约定传输该上行信道时丢弃该第一CSI。
也就是说,终端设备和网络设备可以事先约定第一CSI与该上行信道之间发生资源冲突时传输其中的哪个信号,从而丢弃另一个信号。
方式4
若第一CSI关联的CORESET组索引与该上行信道关联的CORESET组索引不同,终端设备根据接收到的用于指示是否复用传输的指示信息,确定上报还是丢弃第一CSI。
该指示信息例如可以通过RRC信令指示给终端设备,用于指示终端设备关联于不同CORESET组索引的上行信号能否能够复用传输。
例如,若该指示信息指示能够复用传输,则终端设备将第一CSI与该上行信道进行复用传输。比如,将第一CSI与该上行信道携带的信息进行级联后,在同一个PUCCH或同一个PUSCH中传输,其中第一CSI与该上行信道携带的信息可以独立进行编码;或者将第一CSI与该上行信道携带的信息进行联合编码后,在同一个PUCCH或同一个PUSCH中传输。其中,上述的同一个PUCCH或同一个PUSCH可以是该上行信道。
又例如,若该指示信息指示不能够复用传输,则终端设备在该时域资源单元上传输第一CSI和该上行信道中的一个。比如,终端设备可以丢弃掉这两个信号中优先级较低的信号。
又例如,若该指示信息指示不能够复用传输,则终端设备丢弃第一CSI和该上行信道, 即在该时域资源单元上不传输第一CSI和该上行信道。或者说,若该指示信息指示不能够复用传输,终端不期望所述第一CSI和该上行信号被配置在同一个时域资源单元中。如果出现这种情况,终端设备可以将该情况当做一个错误情况(error case),从而不进行处理,即两个信号都不传输。
该实施例中,网络设备可以根据backhaul的情况配置用于指示是否复用的该指示信息,例如,理想backhaul时该指示信息指示允许终端设备对这两个信号进行复用传输,非理想backhaul时该指示信息指示不允许复用传输,从而避免理想backhaul中有信息被丢弃。
方式5
若第一CSI关联的CORESET组索引与该上行信道关联的CORESET组索引不同,终端设备通过不同的天线面板分别传输第一CSI和该上行信道。
可选地,该方法还包括:终端设备根据第一CSI关联的CORESET组索引,确定用于传输该第一CSI的天线面板,并根据所述上行信道关联的CORESET组索引,确定用于传输所述上行信道的天线面板。
例如,每个CORESET组索引都可以对应至少一个SRS资源集合。终端设备根据第一CSI关联的CORESET组索引,确定对应的SRS资源集合,并采用传输该SRS资源集合所使用的天线面板来传输第一CSI。也就是说,传输第一CSI的天线面板为传输第一CSI关联的CORESET组索引对应的SRS资源的天线面板。
类似地,终端设备根据该上行信道关联的CORESET组索引,确定对应的SRS资源集合,并采用传输SRS资源集合所使用的天线面板来传输该上行信道。也就是说,传输该上行信道的天线面板为传输该上行信道关联的CORESET组索引对应的SRS资源的天线面板。
方式6
若第一CSI关联的CORESET组索引与该上行信道关联的CORESET组索引不同,终端设备丢弃第一CSI和该上行信道,即在该时域资源单元上不传输第一CSI和该上行信道。
换句话说,若第一CSI关联的CORESET组索引与该上行信道关联的CORESET组索引不同,终端设备不期望第一CSI与该上行信道在相同的时域资源单元上传输。网络设备在调度终端设备的数据传输时,应当避免关联于不同CORESET组索引的第一CSI和上行信道在同一个时域资源单元上传输。如果出现这种情况,终端设备会将该情况当做error case,从而不进行处理,即两个信号都不传输。
可以看出,上述的对第一CSI的几种处理方式中,由于第一CSI关联于CORESET组索引,通过CORESET组索引可以区分不同TRP对应的CSI,在CSI和其他上行信道之间发生资源冲突时,终端设备能够采用合适的冲突解决方式,从而实现CSI和其他上行信道的有效传输。例如,第一CSI关联的CORESET组索引与该上行信道关联的CORESET组索引相同时,可以认为第一CSI与该上行信道对应于同一个TRP,从而通过复用传输的方式避免信号被丢弃;又例如,第一CSI关联的CORESET组索引与该上行信道关联的CORESET组索引不同时,可以认为第一CSI与该上行信道对应于不同的TRP,网络设备根据backhall情况指示终端设备能否进行复用传输,从而在理想backhall时避免信号被丢弃。
图8是图6所示的方法的另一种可能的实现方式。其中,620可以包括622。如图8所示,该方法包括:
在610中,终端设备获取第一CSI关联的CORESET组索引。
在622中,终端设备根据第一CSI关联的CORESET组索引,确定第一CSI包括的内容。
所述的第一CSI包括的内容,可以指第一CSI包括的CSI信息的类型,也可以指第一CSI包括的CSI信息的值,也可以是指第一CSI包括的CSI信息的计算方式,该计算方式可以用于计算这些信息的具体值。这里,CSI信息可以包括秩指示(Rank Indication,RI)、预编码矩阵指示(Precoding Matrix Indicator,PMI)、信道质量指示(Channel Quality Indicator,CQI)、CSI-RS资源指示(CRI)、同步信号块指示(SSBI)、参考信号接收功率(RSRP)等。本申请对此不做限定。
终端设备可以采用以下方几种方式确定第一CSI包括的内容。
方式1
终端设备根据第一CSI关联的CORESET组索引,确定第一CSI中是否包括RI和/或CQI。
例如,当第一CSI关联的CORESET组索引为第一预设值(比如0)时,第一CSI中包括RI;当第一CSI关联的CORESET组索引为第二预设值(比如1)时,第一CSI中不包括RI,包括PMI和CQI,此时该PMI和该CQI可以基于上报的另一个CSI中包括的RI计算得到,所述另一个CSI关联的CORESET组索引可以是第一预设值。
又例如,当第一CSI关联的CORESET组索引为第一预设值(比如0)时,第一CSI中包括RI和CQI;当第一CSI关联的CORESET组索引为第二预设值(比如1)时,第一CSI中不包括RI和CQI,仅包括PMI,此时该PMI可以基于上报的另一个CSI中包括的RI计算得到,所述另一个CSI关联的CORESET组索引可以是第一预设值。
又例如,当第一CSI关联的CORESET组索引为第一预设值(比如0)时,第一CSI中只包括RI,不包括CQI;当第一CSI关联的CORESET组索引为第二预设值(比如1)时,第一CSI中包括RI和CQI,此时该CQI可以基于第一CSI中的RI和上报的另一个CSI中包括的RI一起计算得到,该另一个CSI关联的CORESET组索引可以是第一预设值。
方式2
终端设备根据第一CSI关联的CORESET组索引,确定第一CSI所包括的PMI和/或CQI的计算方式。从而根据该计算方式得到该CSI的内容。
例如,当第一CSI关联的CORESET组索引为第一预设值(例如为0)时,第一CSI中包括RI、PMI和CQI,该PMI和该CQI基于该RI计算得到;当第一CSI关联的CORESET组索引为第二预设值(例如为1)时,第一CSI中不包括RI,包括PMI和CQI,此时该PMI和该CQI可以基于关联于第一预设值的CORESET组索引的CSI中RI计算得到。
又例如,当第一CSI关联的CORESET组索引为第一预设值(例如为0)时,第一CSI中包括RI、PMI和CQI,其中,该PMI基于该RI计算得到,该CQI基于该PMI和RI以及关联于第二预设值(例如为1)的CORESET组索引的CSI中的PMI和RI计算得到;当第一CSI关联的CORESET组索引为第二预设值时,第一CSI中不包括CQI,仅包括RI和PMI,此时该PMI基于该CSI中的RI计算得到。
方式3
终端设备在第一CSI中包括的秩的值与第三CSI中包括的秩的值的总和不超过预设值 的情况下,确定所述第一CSI中包括的秩的值。其中,第一CSI关联的CORESET组索引和第三CSI关联的CORESET组索引不同。
该预设值例如可以是当前终端设备可以接收的最大传输层数。
例如,该预设值可以是终端设备进行能力上报时所上报的支持的传输层数;或者该预设值可以是网络设备通过RRC信令等配置的最大下行传输层数。
该实施例中,终端设备确定第一CSI中包括的秩(Rank)的值时,需要考虑总的传输层数的限制,即上报的关联于不同CORESET组索引的CSI中,Rank值的总和不能超过该预设值。
一种可能的实现方式中,终端设备针对配置了关联的CORESET组索引的CSI中包括的Rank值进行限制,而不需要对没有配置关联的CORESET组索引的CSI中包括的Rank值进行限制。
例如,如果终端设备被配置了四个CSI上报配置,相应的需要进行4个不同CSI的上报。其中,CSI上报配置1和配置2中分别包括CORESET组索引0和CORESET组索引1,而CSI上报配置3和配置4中不包括CORESET组索引。终端设备在计算CSI时,需要针对CSI上报配置1和配置2对应的CSI进行Rank值的限制,即这两个CSI中的Rank值的总和不应该超过该预设值,而针对CSI上报配置3和配置4对应的CSI不需要进行Rank值的限制。
另一种可能的实现方式中,网络设备可以通过CSI上报配置,直接指示终端设备CSI上报配置对应的CSI是否需要进行Rank值的限制。
该实施例中,不同CORESET组索引可以关联不同的TRP,而不同TRP调度的PDSCH可以同时传输,通过限制不同CORESET组索引(或者说不同TRP)的CSI中的Rank值的总和,可以保证同时调度的PDSCH的总传输层数不超过终端设备的能力。
在确定了第一CSI的内容后,终端设备上报该第一CSI。
另外,若第一CSI关联的CORESET组索引与第四CSI关联的CORESET组索引相同,则第一CSI和第四CSI的空间相关信息的配置也相同。该空间相关信息例如可以是波束。如果第一CSI和第四CSI对应于同一个TRP,则终端设备应该采用相同的发送波束传输第一CSI和第四CSI,从而保证更好的传输性能。
可以看出,上述的确定第一CSI内容的方式中,由于CSI与CORESET组索引相关联,因此终端设备可以通过CORESET组索引对该CSI的内容进行限制,从而提高CSI的传输性能。例如,对第一CSI中的Rank的上报进行限制,从而避免不同TRP同时调度多个PDSCH的传输层数总和超过终端设备的能力。
