图1示出了根据本申请一个实施例的无需通信的方法。图1所示的方法可以由终端设备执行,如图1所示,方法包括:
S110,接收关联关系指示信息。
S110中的关联关系指示信息可以显式指示多个CORESET有关联关系,也可以隐式指示多个CORESET具有关联关系。
S120,根据所述关联关系指示信息,确定多个第一控制资源集合CORESET具有关联关系,所述多个第一CORESET共用第一共用准共址QCL信息。
S120中的多个第一CORESET位于同一个成员载波(Component Carrier,CC),或,所述多个第一CORESET中至少两个第一CORESET所在的CC不同。或者理解为,多个相互关联的CORESET可以位于相同的CC,也可以位于不同的CC。
可选地,在一些实施例中,关联关系指示信息包括天线集合相关信息。对应的,S120中,根据关联关系指示信息,确定多个第一CORESET具有关联关系,包括:根据所述天线集合相关信息,确定所述多个第一CORESET具有关联关系。或者理解为,根据对应的天线集合相关信息是否相同,确定多个第一CORESET是否具有关联关系。
例如,在多个第一CORESET对应的天线集合相关信息相同的情况下,确定多个第一CORESET具有关联关系。
上述的天线集合相关信息可以包括以下信息中的一种:天线集合标识(例如,天线面板编号);参考信号(Reference Signals,RS)资源的相关信息,所述RS资源的相关信息与天线集合之间具有关联关系;RS资源集合的相关信息,所述RS资源集合的相关信息与天线集合之间具有关联关系;CORESET 的配置信息中的传输配置指示(Transmission Configuration Indication,TCI)状态,所述TCI状态与天线集合之间具有关联关系;CORESET的配置信息中的TCI状态对应的RS集合,所述RS集合与天线集合之间具有关联关系;以及,CORESET的配置信息中的TCI状态对应的RS,所述RS与天线集合之间具有关联关系。这里的关联关系可以是网络设备配置给终端设备的,也可以是协议事先约定的。
这里的RS可以是探测参考信号(Sounding Reference Signal,SRS),也可以是信道状态信息参考信号(Channel State Information Reference Signal,CSI-RS)等。这里的RS资源集合的相关信息可以是RS资源集合标识(或索引)。
例如,RS资源集合标识为SRS Resource Set Index,假设终端设备被配置了4个CORESET,分别为CORESET 1、CORESET 2、CORESET 3和CORESET 4,其中,CORESET 1的配置信息中的TCI状态对应SRS Resource Set Index为1,CORESET 2的配置信息中的TCI状态对应的SRS Resource Set Index为2,CORESET 3的配置信息中的TCI状态对应的SRS Resource Set Index为2,CORESET 4的配置信息中的TCI状态对应的SRS Resource Set Index为2,SRS Resource Set Index为1对应天线集合1,SRS Resource Set Index为2对应天线集合2,则可以确定CORESET 2、CORESET 3和CORESET 4具有关联关系。
作为一个例子,天线集合相关信息包括CORESET的配置信息中的TCI状态,在这种情况下,根据天线集合相关信息,确定所述多个第一CORESET具有关联关系,具体可以是根据CORESET的配置信息中的TCI状态,确定所述多个第一CORESET具有关联关系。或者,可以理解为,根据CORESET的配置信息中的TCI状态是否相同来确定这多个第一CORESET是否具有关联关系。
例如,假设终端设备被配置了4个CORESET,分别为CORESET 1、CORESET 2、CORESET 3和CORESET 4,其中,CORESET 1的配置信息中的TCI状态为取值1,CORESET 2的配置信息中的TCI状态为取值2,CORESET 3的配置信息中的TCI状态为取值2,CORESET 4的配置信息中 的TCI状态为取值1,TCI状态取值1对应天线集合1,TCI状态取值2对应天线集合2,则可以确定CORESET 1和CORESET 4具有关联关系,CORESET 2和CORESET 3具有关联关系。
作为另一个例子,天线集合相关信息包括COREET的配置信息中的TCI状态对应的RS集合,在这种情况下,根据天线集合相关信息,确定所述多个第一CORESET,具体可以是根据CORESET的配置信息中的TCI状态对应的RS集合,确定所述多个第一CORESET具有关联关系。或者可以理解为,根据CORESET的配置信息中的TCI状态对应的RS集合是否相同来确定这多个第一CORESET是否具有关联关系。
例如,假设终端设备被配置了4个CORESET,分别为CORESET 1、CORESET 2、CORESET 3和CORESET 4,其中,CORESET 1的配置信息中的TCI状态对应RS集合1,CORESET 2的配置信息中的TCI状态对应RS集合2,CORESET 3的配置信息中的TCI状态对应RS集合1,CORESET 4的配置信息中的TCI状态对应RS集合2和RS集合3,RS集合1对应天线集合1,RS集合2和RS集合3对应天线集合2,则可以确定CORESET 1和CORESET3具有关联关系,CORESET2和CORESET 4具有关联关系。
可选地,在S110中,接收关联关系指示信息,包括:通过以下信息中的至少一种接收所述天线集合相关信息:CORESET的配置信息;CORESET的配置信息中的TCI状态;CORESET的配置信息中的TCI状态对应的RS集合的配置信息;CORESET的配置信息中的TCI状态对应的RS的配置信息;CORESET的配置信息中的TCI状态对应的RS资源的配置信息;RS资源集合的配置信息,所述RS资源集合中的至少一个RS资源为CORESET的配置信息中的TCI状态对应的RS资源;RS资源配置信息,所述RS资源配置信息所配置的至少一个RS资源集合中的至少一个RS资源为CORESET的配置信息中的TCI状态对应的RS资源;以及,报告配置信息,所述报告配置所关联的至少一个RS资源集合中的至少一个RS资源为CORESET的配置信息中的TCI状态对应的RS资源。
可以理解的是,如果通过CORESET的配置信息中的TCI状态对应的RS的配置信息接收天线集合相关信息,则与CORESET关联的天线集合(根据 天线集合相关信息确定出的天线集合)用于传输CORESET上的所有控制信息以及CORESET的配置信息中的TCI状态对应的RS。
或者,如果通过CORESET的配置信息中的TCI状态对应的RS集合的配置信息接收天线集合相关信息,则与CORESET关联的天线集合(根据天线集合相关信息确定出的天线集合)用于传输CORESET上的所有控制信息以及CORESET的配置信息中的TCI状态对应的RS集合中的所有RS。
或者,如果通过CORESET的配置信息中的TCI状态对应的RS的RS资源的配置信息接收天线集合相关信息,则与CORESET关联的天线集合用于传输CORESET上的所有控制信息以及CORESET的配置信息中的TCI状态对应的RS资源上的RS。
或者,如果通过RS资源集合的配置信息接收天线集合相关信息,则与CORESET关联的天线集合用于传输CORESET上的所有控制信息以及RS资源集合中的所有RS资源上的RS。
或者,如果通过RS资源配置信息接收天线集合相关信息,则与CORESET关联的天线集合用于传输CORESET上的所有控制信息以及RS资源配置信息所配置的所有RS资源集合中的所有RS资源上的RS。
或者,如果通过报告配置信息接收天线集合相关信息,则与CORESET关联的天线集合用于传输CORESET上的所有控制信息以及报告配置信息所关联的所有RS资源集合中的所有RS资源上的RS。
例如,RS为CSI-RS,上述的RS资源配置信息(Resource Config参数)可以是RRC信令参数CSI-ResourceConfig中承载的信息,报告配置信息(ReportConfig参数)可以是RRC信令参数CSI-ReportConfig中承载的信息。
可选地,作为一个例子,若天线集合相关信息为天线集合标识、RS资源的相关信息、RS资源集合的相关信息中的一种,则通过CORESET的配置信息或CORESET的配置信息中的TCI状态接收所述天线集合相关信息,或者理解为,若天线集合相关信息为天线集合标识、RS资源的相关信息、RS资源集合的相关信息中的一种,则天线集合相关信息承载在CORESET的配置信息中,或承载在CORESET的配置信息中的TCI状态中。
或者,若天线集合相关信息为CORESET的配置信息中的TCI状态对应 的RS,则通过CORESET的配置信息中的TCI状态接收天线集合相关信息,或者通过CORESET的配置信息中的TCI状态对应的RS集合的配置信息接收天线集合相关信息。或者理解为,若天线集合相关信息为CORESET的配置信息中的TCI状态对应的RS,则天线集合相关信息承载在CORESET的配置信息中的TCI状态中,或天线集合相关信息承载在CORESET的配置信息中的TCI状态对应的RS集合的配置信息中。
或者,若天线集合相关信息为CORESET的配置信息中的TCI状态对应的RS集合,则通过CORESET的配置信息中的TCI状态接收天线集合相关信息。或者理解为,若天线集合相关信息为CORESET的配置信息中的TCI状态对应的RS集合,则天线集合相关信息承载在CORESET的配置信息中的TCI状态中。
或者,若天线集合相关信息为RS资源集合的相关信息,则通过CORESET的配置信息中的TCI状态对应的RS的RS资源配置信息或CORESET的配置信息中的TCI状态对应的RS所在的RS资源集合的配置信息接收天线集合相关信息。或者理解为,若天线集合相关信息为RS资源集合的相关信息,则天线集合相关信息承载在CORESET的配置信息中的TCI状态对应的RS的RS资源配置信息中,或天线集合相关信息承载在CORESET的配置信息中的TCI状态对应的RS所在的RS资源集合的配置信息中。
例如,假设天线集合相关信息为SRS Resource Set Index,CORESET的配置信息中的TCI状态对应的RS为CSI-RS,则SRS Resource Set Index可以承载在NZP-CSI-RS-Resource中,或者SRS Resource Set Index可以承载在NZP-CSI-RS-ResourceSet中。
可选地,在一些实施例中,S120中的多个第一CORESET共用相同的候选TCI状态。在这种情况下,图1所示的方法还包括:在所述候选TCI状态的数量为一个的情况下,将所述候选TCI状态指示的QCL信息确定为所述第一共用QCL信息;在所述候选TCI状态的数量为多个的情况下,接收MAC CE命令,将所述候选TCI状态中由所述MAC CE命令指示的第一目标TCI状态指示的QCL信息,确定为所述第一共用QCL信息。
上述的候选TCI状态可以是网络设备通过RRC信令配置的。
可选地,在一些实施例中,图1所示的方法还包括:确定多个第一CORESET中的目标第一CORESET;将所述目标第一CORESET的QCL信息,确定为所述第一共用QCL信息。在这种情况下,网络设备可以通过RRC信令(或者RRC信令和MAC CE信令)只为目标第一CORESET配置QCL信息,多个第一CORESET中的其他CORESET共用目标第一CORESET的QCL信息。网络设备无需为每个第一CORESET分别配置QCL信息,节省信令开销。
这里的目标第一CORESET可以是多个第一CORESET中满足一定规则(要求)的CORESET。例如,目标第一CORESET为多个第一CORESET中索引为预设值的CORESET,或者目标第一CORESET为多个第一CORESET中索引最小(或最大)的CORESET。
需要说明的是,多个第一CORESET的第一共用QCL信息可以作为多个第一CORESET上传输的控制信息(例如,DCI)对应的控制信道(例如,PDCCH)使用的QCL信息。
进一步地,如图2所示出的,图1所示的方法还包括:
S130,根据所述第一共用QCL信息,确定所述第一CORESET的第一共用波束集合;
S140,将所述第一共用波束集合,确定为所述多个第一CORESET的默认波束集合。
需要说明的是,S140中的第一共用波束集合中的波束可以同时进行信号的传输。例如,终端设备可以同时通过第一共用波束集合中的波束接收多个第一CORESET上的控制信息。
可以理解的是,在S140中将第一共用波束集合确定为多个第一CORESET的默认波束集合后,网络设备和终端设备进行信号传输时,采用第一共用波束(默认波束)进行信号的传输,无需网络设备通过信令进行配置和指示,因此能够进一步节省信令开销。
目前,随着终端设备能力的增强,一个终端设备可能支持多个天线集合(天线面板),对具有多个天线集合的终端设备进行波束配置和指示时,相对于单天线集合的情况,信令开销会进一步增大。
为了解决多天线集合情况下,信令开销增大的问题,本公开的一些实施例中的第一共用波束集合中的波束对应至少一个天线集合。例如,第一共用波束集合中的波束对应一个天线集合。在这种情况下,使用一个天线面板进行传输的所有CORESET共用同一个QCL信息,网络设备可以针对该天线面板所对应的所有CORESET进行统一的QCL信息配置,而无需针对每个CORESET进行QCL信息的配置,能够节省信令开销。
如图3所示出的,图1所示的方法还包括:
S150,确定与所述多个第一CORESET关联的目标参考信号RS或目标信道。
在S150中,目标RS可以包括以下RS中的至少一种:所述多个第一CORESET被配置的TCI状态对应的源RS;对应的源RS与所述多个第一CORESET被配置的TCI状态对应的源RS相同的RS;无线资源控制RRC信令指示的与所述多个第一CORESET关联的RS;介质访问控制控制单元MAC CE指示的与所述多个第一CORESET关联的RS;以及,所述多个第一CORESET对应的天线集合上传输的全部RS(上行RS和下行RS)。
S150中,目标信道包括以下信道中的至少一种:所述多个第一CORESET上传输的物理下行控制信道PDCCH所调度的PDSCH;对应的源RS与所述多个第一CORESET被配置的TCI状态对应的源RS相同的信道;RRC信令指示的与所述多个第一CORESET关联的信道;MAC CE指示的与所述多个第一CORESET关联的信道;所述多个第一CORESET对应的天线集合上传输的全部信道中除所述多个第一CORESET上的信道外的其他信道;以及,所述多个第一CORESET上传输的PDCCH所调度的物理上行共享信道PUSCH。
S160,根据所述第一共用QCL信息,确定所述目标RS或所述目标信道的波束信息。
具体地,在一些实施例中,S160中根据第一共用QCL信息,确定所述目标RS或目标信道的波束信息,包括:在所述目标RS为目标下行RS,所述目标信道为目标下行信道的情况下,将所述第一共用QCL信息确定为所述目标RS或所述目标信道的QCL信息;在所述目标RS为目标上行RS,所述 目标信道为目标上行信道的情况下,根据用于指示所述第一共用QCL信息的传输配置指示TCI状态对应的源RS,确定所述目标RS或所述目标信道的空间关系信息。
因此,本公开的一些实施例的技术方案,可以基于CORESET的QCL信息,确定与该CORESET关联的RS或信道的QCL信息或空间关系信息,由此无需网络设备对与CORESET关联的RS或信道进行QCL信息或空间关系信息的配置与指示,能够进一步节省信令开销。
在本公开的一些实施例中,可选地,图1所示的方法还包括:根据所述关联关系指示信息,确定多个第二CORESET具有关联关系,所述多个第一CORESET与所述多个第二CORESET之间不具有关联关系,所述多个第二CORESET共用第二共用QCL信息。也就是说,允许存在多个独立的相互关联的CORESET集合,每个CORESET集合内的CORESET具有关联关系,不同CORESET集合中的CORESET不具有关联关系。
可选地,在一些实施例中,关联关系指示信息包括天线集合相关信息。对应的,根据关联关系指示信息,确定多个第二CORESET具有关联关系,包括:根据所述天线集合相关信息,确定所述多个第二CORESET具有关联关系。或者理解为,根据对应的天线集合相关信息是否相同,确定多个第二CORESET是否具有关联关系。
例如,在多个第二CORESET对应的天线集合相关信息相同的情况下,确定多个第二CORESET具有关联关系。
进一步地,根据第二共用QCL信息,确定多个第二CORESET的第二共用波束集合;将第二共用波束集合,确定为所述多个第二CORESET的默认波束集合。
这里的第二共用波束集合中的波束对应至少一个天线集合。并且第二波束集合中的波束可以同时进行信号的传输。例如,终端设备可以通过第二共用波束集合中的波束接收多个第二CORESET上的控制信息。
上述的第一共用波束集合与第二共用波束集合不同。第一共用波束集合与第二共用波束集合用于实现多个第一CORESET上的控制信息和多个第二CORESET上的控制信息的同时传输。例如,终端设备通过第一共用波束集合 与第二共用波束集合实现多个第一CORESET上的控制信息和多个第二CORESET上的控制信息的同时接收。
换言之,如果第一共用波束集合对应第一天线面板,第二共用波束集合对应第二天线面板,则第一天线面板和第二天线面板各自对应的波束所传输的信道或参考信号可以同时传输。
在上述所有实施例的基础上,图1所示的方法还包括:确定所述多个第一CORESET上的控制信息所调度的物理下行共享信道(Physical Downlink Shared Channel,PDSCH)的反馈信息所用的第一共用资源;确定所述多个第二CORESET上的控制信息所调度的PDSCH的反馈信息所用的第二共用资源,所述第一共用资源与所述第二共用资源不同。这里的反馈信息可以为ACK/NACK信息。
可选地,作为一个例子,所述第一共用资源为物理上行控制信道(Physical Uplink Control Channel,PUCCH)资源;和/或,所述第二共用资源为PUCCH资源。
例如,具有关联关系的多个CORESET上的下行授权(Downlink Grant,DL Grant)调度的PDSCH的ACK/NACK信息放在相同的PUCCH资源中,不具有关联关系的CORESET上的下行授权调度的PDSCH的ACK/NACK信息放在不同的PUCCH资源中。
以上结合图1至图3详细描述了根据本公开一实施例的无线通信的方法。下面将结合图4详细描述根据本公开另一实施例的无线通信的方法。需要说明的是,从网络设备侧描述的终端设备与网络设备的交互与终端设备侧的描述相同,为避免重复,适当省略相关描述。
图4是根据本公开另一实施例的无线通信的方法。图4的方法可由网络设备执行,如图4所示出的,方法包括:
S410,生成关联关系指示信息,所述关联关系指示信息用于指示多个第一控制资源集合CORESET具有关联关系,所述多个第一CORESET共用第一共用准共址QCL信息。

可以理解的是,如果通过CORESET的配置信息中的TCI状态对应的RS的配置信息发送天线集合相关信息,则与CORESET关联的天线集合(根据天线集合相关信息确定出的天线集合)用于传输CORESET上的所有控制信息以及CORESET的配置信息中的TCI状态对应的RS。
或者,如果通过CORESET的配置信息中的TCI状态对应的RS集合的配置信息发送天线集合相关信息,则与CORESET关联的天线集合(根据天线集合相关信息确定出的天线集合)用于传输CORESET上的所有控制信息以及CORESET的配置信息中的TCI状态对应的RS集合中的所有RS。

可选地,作为一个例子,若天线集合相关信息为天线集合标识、RS资源的相关信息、RS资源集合的相关信息中的一种,则通过CORESET的配置信息或CORESET的配置信息中的TCI状态发送所述天线集合相关信息,或者理解为,若天线集合相关信息为天线集合标识、RS资源的相关信息、RS资源集合的相关信息中的一种,则天线集合相关信息承载在CORESET的配置 信息中,或承载在CORESET的配置信息中的TCI状态中。
或者,若天线集合相关信息为CORESET的配置信息中的TCI状态对应的RS,则通过CORESET的配置信息中的TCI状态接收天线集合相关信息,或者通过CORESET的配置信息中的TCI状态对应的RS集合的配置信息发送天线集合相关信息。或者理解为,若天线集合相关信息为CORESET的配置信息中的TCI状态对应的RS,则天线集合相关信息承载在CORESET的配置信息中的TCI状态中,或天线集合相关信息承载在CORESET的配置信息中的TCI状态对应的RS集合的配置信息中。
