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用的模拟波束。具体的,网络设备可以给终端设备配置SRS资源集合,基于终端设备在SRS资源集合中传输的SRS,选择出接收质量最好的一个SRS资源,并将对应的SRS资源指示(SRS resource indicator,SRI)通知给终端设备。终端设备接收到SRI后,将SRI指示的SRS资源所用的模拟波束确定为传输物理上行共享信道(Physical Uplink Shared Channel,PUSCH)所用的模拟波束。对于DCI调度的PUSCH,所述SRI通过DCI中的SRI指示域来指示;对于无线资源控制(Radio Resource Control,RRC)调度的PUSCH,所述SRI通过相应的调度信令通知。如果用于调度PUSCH的DCI为DCI格式0_0,则DCI中不包含SRI,终端设备将PUSCH所在载波的激活带宽部分(Band Width Part,BWP)上配置了空间相关信息的物理上行控制信道(Physical Uplink Control Channel,PUCCH)中资源标识(Identity,ID)最低的PUCCH资源上的发送波束,作为所述PUSCH的发送波束,同时,终端设备将所述PUCCH的路损测量参考信号,作为所述PUSCH的路损测量参考信号。如果所述DCI格式0_0调度的PUSCH所在载波上的激活BWP上没有配置PUCCH资源,或者所述PUSCH所在载波上的激活BWP上配置的PUCCH资源没有配置空间相关信息,则终端设备可以根据该载波上激活的下行BWP中ID最低的CORESET所用的准共址(Quasi-co-located,QCL)假设(QCL类型D),来得到所述PUSCH的发送波束和路损测量参考信号。例如,可以将所述QCL假设中包含的下行参考信号的接收波束,作为所述PUSCH的发送波束,并将所述下行参考信号作为所述PUSCH的路损测量参考信号。
对于PUCCH,也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RRC信令中配置多个PUCCH空间相关信息(PUCCH-spatialrelationinfo),再通过媒体接入控制(Media Access Control,MAC)层信令从中指示当前所用的PUCCH-spatialrelationinfo。其中,每个PUCCH-spatialrelationinfo中包含一个用于确定PUCCH的发送波束的参考信号,可以是SRS或信道状态信息参考信号(Channel State Information Reference Signal,CSI-RS)或同步信号块(Synchronization Signal Block,SSB)。PUCCH-spatialrelationinfo中还可以包含对应PUCCH的功率控制参数。对于每个SRS资源,也可以通过RRC信令配置对应的SRS空间相关信息(SRS-spatialrelationinfo),其中包含一个用于确定SRS的发送波束的参考信号。如果网络侧没有配置PUCCH-spatialrelationinfo,则终端设备可以采用与PUSCH类似的方法,根据PUCCH所 在的载波上激活的下行BWP中ID最低的控制资源集(Control Resource Set,CORESET)所用的QCL假设(QCL类型D),来得到所述PUCCH的发送波束。例如,可以将所述QCL假设中包含的下行参考信号的接收波束,作为所述PUCCH的发送波束。
在NR系统中,网络设备可以为每个下行信号或下行信道配置相应的传输配置指示(Transmission Configuration Indicator,TCI)状态,指示目标下行信号或目标下行信道对应的QCL参考信号,从而终端基于该参考信号进行目标下行信号或目标下行信道的接收。
其中,一个TCI状态可以包含如下配置:
TCI状态ID,用于标识一个TCI状态;
QCL信息1;
QCL信息2。
其中,一个QCL信息又包含如下信息:
QCL类型(type)配置,可以是QCL type A,QCL type B,QCL type C,QCL type D中的一个;
QCL参考信号配置,包括参考信号所在的小区ID,BWP ID以及参考信号的标识(可以是CSI-RS资源ID或SSB索引)。
其中,QCL信息1和QCL信息2中的至少一个QCL信息的QCL类型必须为typeA,typeB,typeC中的一个,另一个QCL信息(如果配置)的QCL类型必须为QCL type D。
其中,不同QCL类型配置的定义如下:
'QCL-TypeA':{多普勒频移(Doppler shift),多普勒扩展(Doppler spread),平均时延(average delay),延时扩展(delay spread)};
'QCL-TypeB':{多普勒频移(Doppler shift),多普勒扩展(Doppler spread)};
'QCL-TypeC':{多普勒频移(Doppler shift),平均时延(average delay)};
'QCL-TypeD':{空间接收参数(Spatial Rx parameter)}。
如果网络设备通过TCI状态配置目标下行信道的QCL参考信号为参考SSB或参考CSI-RS资源,且QCL类型配置为typeA,typeB或typeC,则终端设备可以假设所述目标下行信道与所述参考SSB或参考CSI-RS资源的目标大尺度参数是相同的,从而采用相同的相应接收参数进行接收,所述目标大尺度参数通过QCL类型配置来确定。类似的,如果网络设备通过TCI状态配置目标下行信道的QCL参考信号为参考SSB或参考CSI-RS资源,且QCL类型配置为type D,则终端设备可以采用与接收所述参考SSB或参考CSI-RS资源相同的接收波束(即Spatial Rx parameter),来接收所述目标下行信道。通常的,目标下行信道与其参考SSB或参考CSI-RS资源在网络侧由同一个TRP或者同一个天线面板(panel)或者相同的波束来发送。如果两个下行信号或下行信道的传输TRP或传输panel或发送波束不同,通常会配置不同的TCI状态。
对于下行控制信道,TCI状态可以通过RRC信令或者RRC信令+MAC信令的方式来指示。对于下行数据信道,可用的TCI状态集合通过RRC信令来指示,并通过MAC层信令来激活其中部分TCI状态,最后通过DCI中的TCI状态指示域从激活的TCI状态中指示一个或两个TCI状态,用于所述DCI调度的PDSCH。例如,如图2所示,网络设备通过RRC信令指示N个候选的TCI状态,并通过MAC信令激活K个TCI状态,最后通过DCI中的TCI状态指示域从激活的TCI状态中指示1个或2个使用的TCI状态。
为了满足物理下行共享信道(Physical Downlink Shared Channel,PDSCH)的传输时延和可靠性需求,版本16(Release 16,Rel-16)中引入了基于多发送接收点(Transmission/Reception Point,TRP)的PDSCH分集传输,通过频分多路复用(Frequency-division multiplexing,FDM)、时分复用模式(Testing Data Management/Technical Data Manage,TDM)或空分复用(Space Division Multiplexing,SDM)的方式接收不同TRP传输的数据。类似的机制也可以用于PUCCH传输,以提高PUCCH的传输可靠性。具体的,终端设备可以在不同的时隙中使用相同的PUCCH资源 重复传输同一个PUCCH(携带相同的上行控制信息(Uplink Control Information,UCI))。由于不同时隙中的PUCCH是发给不同的TRP的,所使用的发送波束和功率控制参数(如路损测量参考信号)也是独立配置的,如图3所示。例如,可以给一个PUCCH资源指示N个空间相关信息PUCCH-spatialrelationinfo或者N个TCI状态,分别用于不同时隙中的PUCCH重复传输,PUCCH的发送波束和功率控制参数可以从所述N个空间相关信息PUCCH-spatialrelationinfo或者N个TCI状态中得到。其中,N为协作TRP的数量,对于两个TRP的情况,N=2,如图4所示。
在本申请实施例中,PUSCH的发送功率可以通过如下公式1计算:
Figure PCTCN2020101907-appb-000001
其中,在公式1中,P CMAX,f,c(i)是终端当前载波上的最大发送功率,i是一次PUSCH传输的索引,j是开环功率控制参数索引(包括目标功率P O_PUSCH,b,f,c(j)和路损因子α b,f,c(j));q d是用于进行路损测量的参考信号的索引,用于得到路损值PL b,f,c(q d),也是一个开环功率控制参数;f b,f,c(i,l)是闭环功控调整状态,其中l是闭环功控调整状态的索引。其中,终端根据网络侧发送的传输功率控制(Transmission Power Control,TPC)命令域来确定闭环功率调整因子,所述TPC命令域可以通过终端搜索空间中用于调度所述PUSCH的DCI来承载,也可以通过公共搜索空间中用于携带组TPC命令域的DCI格式2_2来承载。不同闭环功控调整状态索引对应的闭环功控调整状态是独立计算的,从而可以得到不同的PUSCH发送功率。
由于在引入了基于多TRP的PUCCH分集传输之后,终端设备可以在不同的时隙中使用同一PUCCH资源和不同的传输参数(如发送波束和功率控制参数)重复传输同一个PUCCH。如果PUSCH所在载波的激活BWP上的PUCCH资源ID最低的PUCCH资源被配置了多个空间相关信息(如多个波束),如何确定DCI格式0_0调度的PUSCH的波束和路损测量参考信号是个亟待解决的问题。
基于上述问题,本申请提出了一种用于确定上行传输参数的方案,如果PUSCH所在的载波上激活的上行BWP中的PUCCH资源ID最低的PUCCH资源被配置了多组传输参数(发送波束和/或路损测量参考信号),终端设备可以基于本申请方案确定PUSCH的传输参数(发送波束和/或路损测量参考信号)。具体地,终端设备可以选择未配置多个空间相关信息的其他PUCCH资源来得到PUSCH的传输参数,或者将发给同一TRP的PUCCH的传输参数作为PUSCH的传输参数,或者从下行信号的QCL假设得到PUSCH的传输参数,从而不需要信令就可以解决无法确定PUSCH传输参数的问题。
以下通过具体实施例详述本申请的技术方案。
图5是根据本申请实施例的用于确定上行传输参数的方法200的示意性流程图,如图5所示,该方法200可以包括如下内容中的至少部分内容:
S210,终端设备根据PUSCH所在的载波上激活的上行BWP中的PUCCH资源上的传输参数,确定该PUSCH的传输参数,其中,该PUSCH为采用第一DCI格式调度的PUSCH,该传输参数为发送波束和/或该传输参数为路损测量所用的参考信号。
可选地,该第一DCI格式为DCI格式0_0。
需要说明的是,DCI格式0_0用于PUSCH调度,并且DCI格式0_0中不包括SRS资源指示(SRI)。而对于除DCI格式0_0之外的一些其他的DCI格式调度的PUSCH,网络设备可以给终端设备配置SRS资源集合,基于终端设备在SRS资源集合中传输的SRS,选择出接收质量最好的一个SRS资源,并将对应的SRS资源指示(SRI)通知给终端设备。终端设备接收到SRI后,将SRI指示的SRS资源所用的模拟波束确定为传输PUSCH所用的模拟波束。
也就是说,对于DCI格式0_0调度PUSCH,由于DCI格式0_0中不包括SRS资源指示(SRI),终端设备无法基于SRI指示的SRS资源所用的模拟波束确定传输PUSCH所用的模拟波束。
需要说明的是,在本申请实施例中,PUCCH资源的发送波束和路损测量所用的参考信号可以通过空间相关信息(Spatial relation information)来得到(例如,PUCCH-spatialrelationinfo),也可以通过TCI状态来得到。因此,本申请实施例中PUCCH资源的传输参数可以是指PUCCH资源的空间相关信息或TCI状态。
在本申请实施例中,发送波束也可以称为空间域传输滤波器(Spatial domain transmission filter或者Spatial domain filter for transmission)或者空间关系(Spatial relation)或者空间配置(spatial setting)。接收波束也可以称为空间域接收滤波器(Spatial domain reception filter或者Spatial domain filter for reception)或者空间接收参数(Spatial Rx parameter)。
在本申请实施例中,路损测量所用的参考信号可以为用于测量路损的下行参考信号,例如CSI-RS或SSB,终端设备可以根据测量得到的路损值来计算PUSCH的发送功率,例如基于上述公式1计算PUSCH的发送功率。
可选地,在本申请实施例中,该上行BWP中可以配置多个PUCCH资源,每个PUCCH资源可以独立配置资源标识和PUCCH的传输参数(如通过PUCCH空间相关信息配置)。例如,有的PUCCH资源上没有配置发送波束(例如没有配置PUCCH空间相关信息),有的PUCCH资源只配置单个发送波束(例如只配置一个PUCCH空间相关信息),有的PUCCH资源配置多个发送波束(例如配置多个PUCCH空间相关信息,分别用于不同重复(Repetition)的传输)。也就是说,在本申请实施例中,该上行BWP中可以使用基于多TRP的PUCCH分集传输。
可选地,在本申请实施例中,S210具体可以通过如下示例1至示例3中的一种或者多种方案,确定该PUSCH的传输参数。
示例1,该终端设备将PUSCH所在的载波上激活的上行BWP中仅配置有一组传输参数的PUCCH资源中资源标识最低的PUCCH资源上的传输参数,确定为该PUSCH的传输参数。
在示例1中,例如,如图6所示,PUSCH所在的载波上激活的上行BWP中配置了5个PUCCH资源,分别记为PUCCH资源0、PUCCH资源1、PUCCH资源2、PUCCH资源3和PUCCH资源4,该PUSCH由DCI格式0_0调度。其中,PUCCH资源0上配置有2组传输参数(如PUCCH空间相关信息0和PUCCH空间相关信息1),PUCCH资源1上配置有1组传输参数(如PUCCH空间相关信息2),PUCCH资源2上配置有1组传输参数(如PUCCH空间相关信息3),PUCCH资源3上没有配置传输参数,即PUCCH资源3无PUCCH空间相关信息,PUCCH资源4上配置有2组传输参数(如PUCCH空间相关信息4和PUCCH空间相关信息5)。具体地,终端设备将仅配置有1组传输参数的PUCCH资源包括PUCCH资源1和PUCCH资源2,其中,PUCCH资源1和PUCCH资源2中资源标识最低的PUCCH资源为PUCCH资源1,终端设备可以将PUCCH资源1的传输参数,作为该PUSCH的传输参数。例如,终端设备将PUCCH资源1的发送波束,作为该PUSCH的发送波束。同时,终端设备将PUCCH资源1的路损测量所用的参考信号,作为该PUSCH的路损测量所用的参考信号。
因此,在示例1中,在PUSCH所在的载波上激活的上行BWP中使用基于多TRP的PUCCH分集传输的情况下,终端设备可以将PUSCH所在的载波上激活的上行BWP中仅配置有一组传输参数的PUCCH资源中资源标识最低的PUCCH资源上的传输参数,确定为该PUSCH的传输参数,从而避免了用于得到PUSCH传输参数的PUCCH资源有多组传输参数的问题。
示例2,若PUSCH所在的载波上激活的上行BWP中资源标识最低的PUCCH资源 配置有多组传输参数,该终端设备将该多组传输参数中的目标传输参数,确定为该PUSCH的传输参数。
可选地,在示例2中,该目标传输参数为该多组传输参数中预先约定好的一组传输参数,或者,该目标传输参数为该多组传输参数中预配置的一组传输参数,或者,该目标传输参数为该多组传输参数中网络设备指示的一组传输参数。
例如,该上行BWP中资源标识最低的PUCCH资源配置有两组传输参数,分别用于奇数次的PUCCH重复传输和偶数次的PUCCH重复传输。此种情况下,终端设备可以将两组传输参数中的第一组传输参数,确定为该PUSCH的传输参数。
又例如,此种情况下,该上行BWP中资源标识最低的PUCCH资源配置有两个PUCCH空间相关信息,分别用于奇数次的PUCCH重复传输和偶数次的PUCCH重复传输。终端设备可以将第一个PUCCH空间相关信息所指示的发送波束,作为该PUSCH的发送波束;以及将第一个PUCCH空间相关信息所指示的路损测量参考信号,作为该PUSCH的路损测量参考信号。或者,终端设备可以将第二个PUCCH空间相关信息所指示的发送波束,作为该PUSCH的发送波束;以及将第二个PUCCH空间相关信息所指示的路损测量参考信号,作为该PUSCH的路损测量参考信号。
可选地,在示例2中,该目标传输参数为调度该PUSCH的DCI所在的CORESET的CORESET组索引(CORESETPoolIndex)从该多组传输参数中确定的。
进一步的,在示例2中,该目标传输参数为基于该CORESET组索引和第一对应关系从该多组传输参数中确定的,其中,该第一对应关系为CORESET组索引的取值与传输参数组标识的对应关系。
可选地,该CORESET组索引可以占用N比特,N为大于或者等于1的整数。例如,在N=1的情况下,该CORESET组索引取值可以是0和1。又例如,在N=2的情况下,该CORESET组索引取值可以是00、01、10和11。再例如,在N=3的情况下,该CORESET组索引取值可以是000、001、010、011、100、101、110和111。
可选地,在N=1的情况下,若该CORESET组索引取值为0,该目标传输参数为该多组传输参数中的第一组传输参数;若该CORESET组索引取值为1,该目标传输参数为该多组传输参数中的第二组传输参数。
可选地,在N=2的情况下,若该CORESET组索引取值为00,该目标传输参数为该多组传输参数中的第一组传输参数;若该CORESET组索引取值为01,该目标传输参数为该多组传输参数中的第二组传输参数。
例如,网络设备可以预先为每个CORESET配置一个CORESET组索引(CORESETPoolIndex),不同CORESET可以采用相同的CORESET组索引,也可以采用不同的CORESET组索引。特别的,在该CORESET组索引占用1比特的情况下,如果一个CORESET没有配置CORESET组索引,终端设备可以假设该CORESET的CORESET组索引取值为0。终端设备在第一CORESET中检测到了携带调度该PUSCH的DCI的PDCCH,则终端设备根据该第一CORESET的CORESET组索引,从该多组传输参数中确定目标传输参数。例如,在该CORESET组索引占用1比特的情况下,假设该PUCCH资源被配置了两组传输参数,如果该第一CORESET的CORESET组索引取值为0或者第一CORESET没有配置CORESET组索引,则采用该两组传输参数中的第一组传输参数作为该PUSCH的传输参数;如果该第一CORESET的CORESET组索引取值为1,则采用该两组传输参数中的第二组传输参数作为该PUSCH的传输参数。
可选地,该方法也可以用于PUCCH资源被配置了多于两组传输参数的情况。
因此,在示例2中,在PUSCH所在的载波上激活的上行BWP中使用基于多TRP的PUCCH分集传输的情况下,终端设备可以将分集传输的PUCCH中与PUSCH接收TRP相同的PUCCH的传输参数作为PUSCH的传输参数,从而保证发给同一个TRP的不同信道采用相同的传输参数。
示例3,该终端设备根据PUSCH所在的载波上激活的上行BWP中资源标识最低的PUCCH资源配置的传输参数的数量,确定该PUSCH的传输参数。
例如,PUSCH所在的载波上激活的上行BWP中配置了3个PUCCH资源,分别记为PUCCH资源0、PUCCH资源1和PUCCH资源2,此种情况下,终端设备可以根据PUCCH资源0配置的传输参数的数量,确定该PUSCH的传输参数。
可选地,在示例3中,若该传输参数的数量等于1,该终端设备将该上行BWP中资源标识最低的PUCCH资源配置的传输参数,确定为该PUSCH的传输参数;
若该传输参数的数量大于1,该终端设备从目标CORESET所用的QCL假设中得到该PUSCH的传输参数,其中,该目标CORESET为该PUSCH所在的载波上激活的下行BWP上配置的CORESET中,CORESET标识最低的CORESET。
例如,PUSCH所在的载波上激活的下行BWP上配置了3个CORESET,分别为CORESET 0、CORESET 1和CORESET 2,则CORESET标识最低的CORESET为CORESET 0,即目标CORESET为CORESET 0。
需要说明的是,网络设备可以预先为每个CORESET配置一个CORESET标识,不同CORESET的CORESET标识是不同的,用于标识此CORESET。例如,传输参数为路损测量所用的参考信号时,终端设备将目标CORESET所用的QCL假设(QCL类型为QCL type-D)对应的下行参考信号,作为所述PUSCH的路损测量所用的参考信号。又例如,传输参数为发送波束时,终端设备将目标CORESET所用的QCL假设(QCL类型为QCL type-D)对应的下行参考信号的接收波束,作为所述PUSCH的发送波束。
可选地,在示例3中,若该传输参数的数量等于1,该终端设备将该上行BWP中资源标识最低的PUCCH资源配置的传输参数,确定为该PUSCH的传输参数;
若该传输参数的数量大于1,该终端设备从目标CORESET所用的QCL假设中得到该PUSCH的传输参数,其中,该目标CORESET为调度该PUSCH的DCI所在的CORESET。
例如,终端设备在CORESET 1中检测到了携带调度该PUSCH的DCI的PDCCH,则从CORESET 1所用的QCL假设中,得到所述PUSCH的传输参数。例如,当传输参数为路损测量所用的参考信号时,终端设备将CORESET 1所用的QCL假设(QCL类型为QCL type-D)对应的下行参考信号,作为所述PUSCH的路损测量所用的参考信号。又例如,当传输参数为发送波束时,终端设备将CORESET 1所用的QCL假设(QCL类型为QCL type-D)对应的下行参考信号的接收波束,作为所述PUSCH的发送波束。
可选地,在示例3中,若该传输参数的数量等于1,则该终端设备将该上行BWP中资源标识最低的PUCCH资源配置的传输参数,确定为该PUSCH的传输参数;
若该传输参数的数量大于1,该终端设备从目标TCI状态中得到该PUSCH的传输参数,其中,该目标TCI状态为该PUSCH所在的载波上激活的下行BWP中所激活的用于PDSCH传输的TCI状态中TCI状态标识最低的TCI状态。
例如,PUSCH所在的载波上激活的下行BWP上配置了5个TCI状态,分别为TCI状态0、TCI状态1、TCI状态2、TCI状态3和TCI状态4,其中,处于激活状态的的用于PDSCH传输的TCI状态包括:TCI状态2、TCI状态3和TCI状态4。则PUSCH所在的载波上激活的下行BWP中所激活的用于PDSCH传输的TCI状态中TCI状态标识最低的TCI状态标识为TCI状态2,即目标TCI状态为TCI状态2。
需要说明的是,网络设备预先通过媒体接入控制控制元素(Media Access Control Control Element,MAC CE)激活用于PDSCH传输的TCI状态。
例如,当传输参数为路损测量所用的参考信号时,终端设备将PUSCH所在的载波上激活的下行BWP中所激活的用于PDSCH传输的TCI状态中,TCI状态标识最低的TCI状态中包含的下行参考信号(QCL类型为QCL type-D),作为PUSCH的路损测量所用的参考信号。又例如,在传输参数为发送波束时,终端设备将PUSCH所在的载波上激活 的下行BWP中所激活的用于PDSCH传输的TCI状态中,TCI状态标识最低的TCI状态中包含的下行参考信号(QCL类型为QCL type-D)的接收波束,作为PUSCH的发送波束;或者,终端设备将PUSCH所在的载波上激活的下行BWP中所激活的用于PDSCH传输的TCI状态中,TCI状态标识最低的TCI状态中包含的上行参考信号的发送波束,作为PUSCH的发送波束。
因此,在示例3中,终端设备可以根据PUSCH所在的载波上激活的上行BWP中资源标识最低的PUCCH资源配置的传输参数的数量,即根据该PUCCH资源是否进行的基于多TRP的PUCCH分集传输,采用相应不同的方法来确定PUSCH的传输参数,从而同时支持单TRP的PUCCH传输和多TRP协作的PUCCH分集传输两种场景。
可选的,在本申请实施例中,配置不同CORESET组索引的CORESET可以来自不同的TRP,例如,配置CORESET组索引为0的CORESET传输自TRP 0,配置CORESET组索引为1的CORESET传输自TRP 1。
可选地,在一些实施例中,该终端设备根据所确定的该PUSCH的传输参数,传输该PUSCH。
例如,在确定该PUSCH的发送波束之后,终端设备可以采用该发送波束来发送该PUSCH。
例如,在确定该PUSCH的路损测量所用的参考信号之后,终端设备可以采用该参考信号进行路损测量,并根据测量得到的路损值来计算该PUSCH的发送功率。
因此,本申请实施例中,在PUSCH所在的载波上激活的上行BWP中资源标识最低的PUCCH资源被配置了多个空间相关信息的情况下,终端设备可以确定DCI格式0_0调度的PUSCH的传输参数。或者,在PUSCH所在的载波上激活的上行BWP中使用基于多TRP的PUCCH分集传输的情况下,终端设备可以确定DCI格式0_0调度的PUSCH的传输参数。进一步的,终端设备可以选择未配置多个空间相关信息的其他PUCCH资源来得到PUSCH的传输参数,或者将发给同一TRP的PUCCH的传输参数作为PUSCH的传输参数,或者从下行信号的QCL假设得到PUSCH的传输参数,从而不需要信令就可以解决无法确定PUSCH传输参数的问题。
