在NR中,对于上行波束的管理可以采用以下处理方式:终端可以采用模拟波束来传输上行数据和上行控制信息。终端可以基于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。图2是根据本申请一个具体实施例所涉及的上行波束管理的过程示意图,如图2所示,网络可以给终端配置SRS资源集合1,集合中包含N个SRS资源(N>1)。终端可以采用不同的波束发送N个SRS资源,网络设备分别对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。网络设备可以再配置一个SRS资源集合2,其中包括K个SRS资源,并令终端采用集合1中选择出来的K个SRS资源所用的模拟波束来传输集合2中的SRS资源。这可以通过将集合1中选择出的K个SRS资源分别配置为集合2中的K个SRS资源的参考SRS资源来实现。此时,基于终端在SRS资源集合2中传输的SRS,网络设备可以选择出接收质量最好的一个SRS资源,并将对应的SRI通知给终端。终端接收到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。对于PUSCH,SRI通过DCI中的SRI指示域来指示。
对于物理下行控制信道(Physical Downlink Control Channel,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-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。对于每个SRS资源,也可以通过RRC信令配置对应的SRS-spatialrelationinfo,其中包含一个用于确定SRS的发送波束的参考信号。
在NR系统中,对于下行信号传输的准共址(Quasi-Co-location,QCL)指示可以采用以下方式:网络设备可以为每个下行信号或下行信道配置相应的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:
(1)TCI状态ID,用于标识一个TCI状态;
(2)QCL信息1
(3)QCL信息2
其中,一个QCL信息又包含如下信息:
(1)QCL类型配置,可以是QCL type A,QCL typeB,QCL typeC或QCL typeD中的一个;
(2)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,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:
(1)'QCL-TypeA':{Doppler shift,Doppler spread,average delay,delay spread}
(2)'QCL-TypeB':{Doppler shift,Doppler spread}
(3)'QCL-TypeC':{Doppler shift,average delay}
(4)'QCL-TypeD':{Spatial Rx parameter}
如果网络设备通过TCI状态配置目标下行信道的QCL参考信号为参考同步信号块(Synchronization Signal Block,SSB)或参考信道状态信息参考信号(Channel State Information Reference signal,CSI-RS)资源,且QCL类型配置为typeA,typeB或typeC,则终端可以假设目标下行信号与参考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,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typeD,则终端可以采用与接收参考SSB或参考CSI-RS资源相同的接收波束(即Spatial Rx parameter),来接收目标下行信号。通常的,目标下行信道与它的参考SSB或参考CSI-RS资源在网络设备由同一个TRP或者同一个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,图3是根据本申请一个具体实施例所涉及的PDSCH的TCI状态配置方法的示意图,如图3所示,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DCI调度的PDSCH。
对于上行信号,上行信号的发射功率由上行信号的功率控制参数确定,上行信号的功率控制参数可以包括多种,例如,可以包括以下至少之一:用于确定目标接收功率的参数,用于确定路损加权因子的参数,用于路损测量的下行参考信号,用于确定闭环功控调整状态的参数。
例如,在相关技术中,PUSCH的发送功率可以通过如下公式计算:
Figure PCTCN2020073819-appb-000001
其中,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)是闭环功率控制调整因子,其中l是闭环功率控制进程的索引。其中,终端根据网络设备发送的TPC命令域来确定闭环功率调整因子,TPC命令域可以通过UE搜索空间中用于调度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 format 2_2来承载。
在NR中,终端基于DCI中的SRI来确定所调度的PUSCH的发送波束,也基于SRI来确定PUSCH所用的功率控制参数。可选地,网络设备预先通过RRC信令配置多个SRI-PUSCH-PowerControl参数域,每个参数域对应一个SRI取值,参数域中包含该SRI取值对应的一组PUSCH功率控制参数配置(例如j,qd,l)。当SRI指示的值不同时,采用对应的参数域(SRI-PUSCH-PowerControl)中的功率控制参数配置来确 定当前调度的PUSCH的发送功率。
又例如,在相关技术中,SRS的发送功率可以通过如下公式计算:
Figure PCTCN2020073819-appb-000002
其中,i是一次SRS传输的索引,q s是开环功率控制参数索引(包括目标功率P O_SRS,b,f,c(q s)和路损因子α SRS,b,f,c(q s));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;h b,f,c(i,l)是闭环功率控制调整因子,其中l是闭环功率控制进程。其中,q d和q d包含在SRS资源集合的配置参数中,通过高层信令配置给终端。如果高层信令配置SRS和PUSCH采用相同的功率控制进程,则h b,f,c(i,l)=f b,f,c(i,l)。如果高层信令配置SRS采用独立的功率控制进程,则网络设备通过公共搜索空间中的DCI format 2_3指示每个终端各自的SRS的TPC命令,终端根据自己的TPC命令确定闭环功率调整因子,与PUSCH闭环功率调整因子无关。
在上述相关技术的基础上,在NR的演进中,上行信号的发送波束也可以通过TCI状态来指示,即终端设备可以通过与下行类似的TCI状态来得到参考信号,用于获得目标上行信号的发送波束。在这种情况下,相应上行信号的功率控制参数如何确定以得到合适的发送功率是需要解决的问题。
因此,本申请实施例提出了一种功率控制参数确定方法。图4为本申请实施例提供的一种功率控制参数确定方法一的示意性流程图,如图4所示,该方法包括:
S402,确定上行信号采用的目标传输配置指示TCI状态,其中,该TCI状态可以包括多项信息,例如,可以包括以下信息之一:QCL类型,参考源信号(例如,可以是参考源信号ID),参考服务小区,参考带宽部分(Bandwidth part,BWP);
S404,根据目标TCI状态,确定上行信号的功率控制参数,其中,该目标TCI状态可以是用于确定上行信号的发送波束的TCI状态,也可以是专门用于确定功率控制参数的TCI状态,等。该功率控制参数也可以包括多种,例如,可以包括以下至少之一:用于确定目标接收功率的参数,用于确定路损加权因子的参数,用于路损测量的下行参考信号,用于确定闭环功控调整状态的参数。
通过上述处理,终端可以根据确定的上行信号采用的TCI状态(例如,网络设备配置的TCI状态)来确定功率控制参数,从而得到合适的发送功率来发送上行信号, 进而提供了一种终端依据TCI状态来确定上行信号的功率控制参数的标准,使得终端能够以合适的发射功率来发送该上行信号,达到适应技术标准发展的需要。
作为一种可选的实施例,该方法的执行主体可以是终端,终端可以是移动终端,例如,可以是一些智能手机、智能汽车、无人机、机器人等5G移动终端。
作为一种可选的实施例,根据目标TCI状态,确定上行信号的功率控制参数时,可以采用多种方式,例如,在网络设备向终端配置TCI状态与功率控制参数之间的对应关系的情况下,可以依据配置的该对应关系来确定该功率控制参数。比如,根据目标TCI状态,以及TCI状态与功率控制参数之间的对应关系,确定上行信号的功率控制参数。
作为一种可选的实施例,上述对应关系可以通过多种方式确定,例如,可以通过以下方式至少之一,确定TCI状态与功率控制参数之间的对应关系:
(1)用于配置TCI状态的第一高层信令中包含TCI状态对应的功率控制参数;即在网络设备向终端配置TCI状态的高层信令中直接包含TCI状态本身,以及与该TCI状态对应的功率控制参数。需要说明的是,该高层信令中包括的TCI状态可以是多个,因此,该高层信令中也包括与该多个TCI状态分别对应的功率控制参数。
(2)接收通过第二高层信令配置的TCI状态的TCI状态标识ID与功率控制参数之间的对应关系,根据对应关系确定TCI状态与功率控制参数之间的对应关系;即网络设备通过向终端配置TCI状态ID与功率控制参数之间的对应关系的方式,来向终端配置该TCI状态ID所标识的TCI状态与功率控制参数之间的对应关系。
(3)通过无线资源控制RRC信令和媒体接入控制控制单元MAC CE,确定TCI状态与功率控制参数之间的对应关系,其中,RRC信令用于配置TCI状态与功率控制参数的初始对应关系,MAC CE用于激活或更新初始对应关系。即通过RRC信令先配置初始对应关系,之后依据MAC CE激活或更新该初始对应关系,从而得到激活或更新后的TCI状态与功率控制参数之间的对应关系。需要说明的是,更新初始对应关系可以是分别更新TCI状态或者功率控制参数,即只要更新其中一项,即是对对应关系的更新。另外,该MAC CE可以只更新一个TCI状态对应的多个功率控制参数中的部分参数。
需要说明的是,上述确定TCI状态与功率控制参数之间的对应关系的方式,可以依据具体情况灵活选择,也可以依据网络设备与终端通信与采用的不同信令来选择。
又例如,在网络设备没有向终端配置TCI状态与功率控制参数之间的对应关系的情况下,即在终端没有接收到用于配置TCI状态与功率控制参数之间的对应关系的信令的情况下,确定功率控制参数候选集合中索引最低的功率控制参数为上行信号的功 率控制参数。
通过上述处理,分别针对网络设备向终端配置TCI状态与功率控制参数之间的对应关系,以及网络设备没有向终端配置TCI状态与功率控制参数之间的对应关系,来确定上行信号的功率控制参数。即不管网络设备有没有向终端配置上述对应关系,终端均能够依据上行信号所采用的目标TCI状态,来确定该上行信号的功率控制参数,从而使用合适的发送功率发送该上行信号。
作为一种可选的实施例,根据目标TCI状态,确定上行信号的功率控制参数时,还可以包括:在目标TCI状态所指示的参考源信号为上行参考信号的情况下,确定目标TCI状态所指示的参考源信号的功率控制参数为上行信号的功率控制参数。即在目标TCI状态所指示的参考源信号为上行参考信号的情况下,该参考源信号的功率控制参数即为该上行信号的功率控制参数。
作为一种可选的实施例,根据目标TCI状态,确定上行信号的功率控制参数,还可以包括:在目标TCI状态所指示的参考源信号为下行参考信号,并且功率控制参数为用于路损测量的下行参考信号的情况下,确定目标TCI状态所指示的参考源信号为上行信号的功率控制参数。即在目标TCI状态所指示的参考源信号为下行参考信号,并且功率控制参数为用于路损测量的下行参考信号的情况下,该参考源信号即为该上行信号的功率控制参数。
作为一种可选的实施例,在上行信号为SRS且功率控制参数为闭环功控调整状态的情况下,根据目标TCI状态,确定上行信号的功率控制参数,还可以包括:一个SRS资源集合中不同SRS资源上的SRS根据目标TCI状态确定的闭环功控调整状态相同。虽然一个SRS资源集合中的不同SRS资源可以对应不同的目标TCI状态,但是根据这些目标TCI状态和TCI状态与功率控制参数之间的对应关系,确定出的闭环功控调整状态是相同的。通过上述处理,一个SRS资源集合可以用于一个panel上的SRS传输,而同一个panel(对应同一个SRS资源集合)采用相同的闭环功控调整状态,不同的panel采用不同的闭环功控调整状态,可以实现每个panel独立的的SRS闭环功率控制。
作为一种可选的实施例,终端还可以接收网络设备配置的载波集合,其中,该载波集合中的每个载波上至少一个与上行信号类型相同的上行信号也采用目标TCI状态,或者,载波集合中的每个载波上至少一个与上行信号类型相同的上行信号采用与目标TCI状态的TCI状态ID相同的TCI状态。通过上述处理,只需要通过很少的信令指示,就能够确定多个载波上的上行信号的功率控制参数,即,使得终端在载波集合中的每个载波上的上行信号能够得到合适的发送功率。
作为一种可选的实施例,目标TCI状态可以根据不同的上行信号类型而采用不同的确定方式。下面以上行信号为PUSCH,PUCCH,SRS以及PRACH分别举例说明。
可选地,在上行信号为PUSCH的情况下,确定上行信号采用的目标TCI状态,可以包括:确定目标TCI状态为用于调度PUSCH的下行控制信息DCI中TCI状态指示信息所指示的TCI状态。
其中,目标TCI状态可以为TCI状态指示信息从MAC CE激活的至少一个用于PUSCH传输的候选TCI状态中指示的TCI状态。
在上行信号为物理上行共享信道PUSCH,并且用于调度PUSCH的DCI中不包含TCI状态指示信息或者用于调度该PUSCH的DCI与PUSCH之间的时间间隔小于预设门限值的情况下,确定上行信号采用的目标TCI状态,包括以下之一:确定目标TCI状态为MAC CE激活的至少一个用于PUSCH传输的候选TCI状态中TCI状态标识ID最低的TCI状态;确定目标TCI状态为MAC CE激活的第一个用于PUSCH传输的候选TCI状态;确定目标TCI状态为DCI中的TCI状态指示信息的最小指示值所指示的TCI状态;确定目标TCI状态为无线资源控制RRC配置的至少一个TCI状态中TCI状态ID最低的TCI状态;确定目标TCI状态为承载DCI的PDCCH所在的控制资源集CORESET所用的TCI状态。
可选地,在上行信号为PUCCH的情况下,确定上行信号采用的目标TCI状态,可以包括以下至少之一:确定目标TCI状态为MAC CE激活的一个用于PUCCH传输的TCI状态;在没有接收到激活用于PUCCH传输的TCI状态的MAC CE的情况下,确定目标TCI状态为RRC配置的至少一个TCI状态中TCI状态ID最低的TCI状态。
可选地,在上行信号为SRS的情况下,确定上行信号采用的目标TCI状态,可以包括以下之一:确定目标TCI状态为RRC配置的一个用于SRS传输的TCI状态;确定目标TCI状态为MAC CE指示的一个用于SRS传输的TCI状态;确定目标TCI状态为承载SRS的SRS资源所在的SRS资源集合中的一个预设SRS资源所采用的TCI状态。
其中,确定目标TCI状态为MAC CE指示的一个用于SRS传输的TCI状态时,在SRS为准持续性SRS的情况下,MAC CE为用于激活准持续性SRS的MAC CE。
其中,确定目标TCI状态为承载SRS的SRS资源所在的SRS资源集合中的一个预设SRS资源所采用的TCI状态时,一个SRS资源集合中不同SRS资源上传输的SRS都基于一个预设的SRS资源所采用的TCI状态确定目标TCI状态,即不同SRS资源上传输的SRS采用相同的目标TCI状态,就可以确定相同的功率控制参数,从而达到SRS资源集合内功率不变的效果。
可选地,在该上行信号为非周期性SRS的情况下,确定上行信号采用的目标TCI状态,可以包括:确定目标TCI状态为用于触发非周期性SRS的DCI所指示的TCI状态。
可选地,在上行信号为物理随机接入信道PRACH的情况下,确定上行信号采用的目标TCI状态,可以包括以下之一:确定目标TCI状态为RRC配置的一个用于PRACH传输的TCI状态;确定目标TCI状态为MAC CE指示的一个用于PRACH传输的TCI状态。
通过上述上行功率控制参数确定方法,终端根据为上行信号配置的TCI状态,确定与该TCI状态关联的功率控制参数,从而根据确定的功率控制参数得到该上行信号的发送功率。功率控制参数可以根据不同的上行信号类型而采用不同的指示方式。对应于上述不同的指示方式,终端采用不同的确定方式,因此,终端设备可以根据不同的上行信号类型,采用不同的功率控制参数确定方式,从而支持用不同的发送波束发送上行信号时,可以确定不同的功率控制参数,以得到适合当前传输的发送功率。
本申请实施例还提出了一种功率控制参数确定方法,图5为本申请实施例提供的一种功率控制参数确定方法二的示意性流程图,如图5所示,该方法包括:

通过上述处理,网络设备可以根据为终端配置的上行信号采用的目标TCI状态来为终端配置该上行信号的功率控制参数,从而使得终端得到合适的发送功率来发送上行信号,进而提供了一种网络设备依据TCI状态来为终端配置上行信号的功率控制参数的标准,使得终端能够以合适的发射功率来发送该上行信号,达到适应技术标准发展的需要。
作为一种可选的实施例,该方法的执行主体可以是网络设备,该网络设备可以是上述所说明的网络设备110。
作为一种可选的实施例,根据目标TCI状态,为终端配置上行信号的功率控制参数,可以采用多种方式,例如,在网络设备向终端配置TCI状态与功率控制参数之间的对应关系的情况下,可以依据配置的该对应关系来为终端配置上行信号的功率控制 参数。比如,为终端配置TCI状态与功率控制参数之间的对应关系;根据目标TCI状态,以及对应关系,为终端配置上行信号的功率控制参数。
作为一种可选的实施例,上述对应关系可以通过多种方式确定,例如,可以通过以下方式至少之一,为终端配置TCI状态与功率控制参数之间的对应关系:
(1)用于配置TCI状态的第一高层信令中包含TCI状态对应的功率控制参数;即在网络设备向终端配置TCI状态的高层信令中直接包含TCI状态本身,以及与该TCI状态对应的功率控制参数。需要说明的是,该高层信令中包括的TCI状态可以是多个,因此,该高层信令中也包括与该多个TCI状态分别对应的功率控制参数。
(2)通过第二高层信令配置TCI状态的TCI状态标识ID与功率控制参数之间的对应关系的方式,为终端配置TCI状态与功率控制参数之间的对应关系;即网络设备通过向终端配置TCI状态ID与功率控制参数之间的对应关系的方式,来向终端配置该TCI状态所标识的TCI与功率控制参数之间的对应关系。
(3)通过无线资源控制RRC信令配置TCI状态与功率控制参数的初始对应关系,以及通过MAC CE激活或更新初始对应关系的方式,为终端配置TCI状态与功率控制参数之间的对应关系。即通过RRC信令先配置初始对应关系,之后依据MAC CE激活或更新该初始对应关系,从而得到激活或更新后的TCI状态与功率控制参数之间的对应关系。需要说明的是,更新初始对应关系可以是分别更新TCI状态或者功率控制参数,即只要更新其中一项,即是对对应关系的更新。
需要说明的是,上述为终端配置TCI状态与功率控制参数之间的对应关系的方式,可以依据具体情况灵活选择,也可以依据网络设备与终端通信与采用的不同信令来选择。
通过上述处理,分别针对网络设备向终端配置TCI状态与功率控制参数之间的对应关系,以及网络设备没有向终端配置TCI状态与功率控制参数之间的对应关系,来为终端配置上行信号的功率控制参数。即不管网络设备有没有向终端配置上述对应关系,网络设备均能够依据上行信号所采用的目标TCI状态,来为终端配置上行信号的功率控制参数,从而使用合适的发送功率发送该上行信号。
作为一种可选的实施例,在上行信号为SRS且功率控制参数为闭环功控调整状态的情况下,根据目标TCI状态以及对应关系,为终端配置上行信号的功率控制参数,包括:一个SRS资源集合中不同SRS资源上的SRS根据目标TCI状态配置的闭环功控调整状态相同。虽然一个SRS资源集合中的不同SRS资源可以对应不同的目标TCI状态,但是根据这些目标TCI状态和TCI状态与功率控制参数之间的对应关系,确定出的闭环功控调整状态是相同的。通过上述处理,一个SRS资源集合可以用于一个 panel上的SRS传输,而同一个panel(对应同一个SRS资源集合)采用相同的闭环功控调整状态,不同的panel采用不同的闭环功控调整状态,可以实现每个panel独立的的SRS闭环功率控制。
作为一种可选的实施例,网络设备还可以向终端发送载波集合,其中,该载波集合中的每个载波上至少一个与上行信号类型相同的上行信号也采用目标TCI状态,或者,载波集合中的每个载波上至少一个与上行信号类型相同的上行信号采用与目标TCI状态的TCI状态ID相同的TCI状态。通过上述处理,网络设备只需要通过很少的信令指示,就能够为终端配置多个载波上的上行信号的功率控制参数,即,使得终端在载波集合中的每个载波上的上行信号能够得到合适的发送功率。
作为一种可选的实施例,可以根据不同的上行信号类型而采用不同的配置方式,为终端配置上行信号采用的目标TCI状态。下面以上行信号为PUSCH,PUCCH,SRS以及PRACH分别举例说明。
可选地,在上行信号为物理上行共享信道PUSCH的情况下,为终端配置上行信号采用的目标TCI状态,可以包括:配置用于调度PUSCH的下行控制信息DCI中TCI状态指示信息所指示的TCI状态为目标TCI状态。
其中,目标TCI状态为TCI状态指示信息从MAC CE激活的至少一个用于PUSCH传输的候选TCI状态中指示的TCI状态。
在上行信号为物理上行共享信道PUSCH,并且用于调度PUSCH的DCI中不包含TCI状态指示信息或者用于调度PUSCH的DCI与PUSCH之间的时间间隔小于预设门限值的情况下,为终端配置上行信号采用的目标TCI状态,可以包括以下之一:配置MAC CE激活的至少一个用于PUSCH传输的候选TCI状态中TCI状态标识ID最低的TCI状态为目标TCI状态;配置MAC CE激活的第一个用于PUSCH传输的候选TCI状态为目标TCI状态;配置DCI中的TCI状态指示信息的最小指示值所指示的TCI状态为目标TCI状态;配置无线资源控制RRC配置的至少一个TCI状态中TCI状态ID最低的TCI状态为目标TCI状态;配置承载DCI的PDCCH所在的控制资源集CORESET所用的TCI状态为目标TCI状态。
可选地,在上行信号为物理上行控制信道PUCCH的情况下,为终端配置上行信号采用的目标TCI状态,可以包括以下至少之一:配置MAC CE激活的一个用于PUCCH传输的TCI状态为目标TCI状态;在没有发送激活用于PUCCH传输的TCI状态的MAC CE的情况下,配置RRC配置的至少一个TCI状态中TCI状态ID最低的TCI状态为目标TCI状态。
可选地,在上行信号为探测参考信号SRS的情况下,为终端配置上行信号采用的 目标TCI状态,可以包括以下之一:配置RRC配置的一个用于SRS传输的TCI状态为目标TCI状态;配置MAC CE指示的一个用于SRS传输的TCI状态为目标TCI状态;配置承载SRS的SR资源所在的SRS资源集合中的一个预设SRS资源所采用的TCI状态为目标TCI状态。
其中,配置MAC CE指示的一个用于SRS传输的TCI状态为目标TCI状态时,在SRS为准持续性SRS的情况下,MAC CE为用于激活准持续性SRS的MAC CE。
其中,配置承载SRS的SR资源所在的SRS资源集合中的一个预设SRS资源所采用的TCI状态为目标TCI状态时,一个SRS资源集合中不同SRS资源上传输的SRS都基于一个预设的SRS资源所采用的TCI状态确定目标TCI状态,即不同SRS资源上传输的SRS采用相同的目标TCI状态,就可以确定相同的功率控制参数,从而达到SRS资源集合内功率不变的效果。

通过上述上行功率控制参数确定方法,网络设备根据为终端配置上行信号采用的TCI状态,为终端配置上行信号的功率控制参数,从而使得终端能够根据确定的功率控制参数得到该上行信号的发送功率。功率控制参数可以根据不同的上行信号类型而采用不同的指示方式,使得终端设备可以根据不同的上行信号类型,采用不同的功率控制参数确定方式,从而支持用不同的发送波束发送上行信号时,可以确定不同的功率控制参数,以得到适合当前传输的发送功率。
结合上述实施例及优选实施例,下面对上行信号分别为PUSCH,PUCCH以及SRS的具体的实施例进行说明。
实施例1:(PUSCH)
1.终端设备根据高层信令确定至少一个TCI状态与PUSCH功率控制参数的对应关系。
这里假设至少一个TCI状态为M个TCI状态(M>=1)。可以采用以下两种配置方式来确定对应关系:
方式1:网络设备通过高层信令配置M个TCI状态,每个TCI状态的配置信息除了包含TCI状态本身的配置(如QCL参考信号的信息等),还可以包含所对应功率控 制参数的信息(如目标接收功率和路损因子,路损测量的下行参考信号和闭环功控调整状态索引等)。
例如,通过RRC配置的一个TCI状态的配置信息可以包括:(其中前面四个参数用于确定QCL参考信号,后面三个参数为对应的功率控制参数。)
Figure PCTCN2020073819-appb-000003
作为一种可选的实施例,网络设备可以通过MAC CE来激活或更新至少一个TCI状态中的任意一个TCI状态对应的功率控制参数。图6为本申请实施例提供的一种通过MAC CE来更新TCI状态对应的功率控制参数的示意图,如图6所示,例如,可以通过以下MAC CE来更新一个TCI状态的配置信息中包含的路损测量参考信号。
其中,Si对应RRC预先配置的一个Pathloss RS,采用bitmap的方式指示所更新的pathloss RS。也可以采用直接指示Pathloss RS索引或ID的方式。
作为一种可选的实施例,终端设备可以接收网络设备通过高层信令配置的载波集合,当网络设备通过MAC CE激活或更新至少一个TCI状态中的某个TCI状态时,这个载波集合中的每个载波上的与所激活/更新的TCI状态的TCI状态ID相同的TCI状态都会被激活/更新。该方法可以只用于激活/更新每个载波上与该PUSCH所在的BWP的BWP ID相同的BWP上的TCI状态,或者只用于激活/更新每个载波上当前被激活的BWP上的TCI状态。
方式2:网络设备通过高层信令配置M个TCI状态,再通过另一个高层信令配置与这M个TCI状态中每个TCI状态分别对应的功率控制参数,具体的,网络设备可以配置每个TCI状态ID对应的功率控制参数。
例如,用于配置一个TCI状态的RRC信令如下:
Figure PCTCN2020073819-appb-000004
例如,用于配置一个TCI状态对应的功率控制参数的RRC信令如下:(其中后面三个参数为TCI-StateId指示的TCI状态所对应的功率控制参数,每个TCI状态都对应一个TCI-PowerControl域)。该指示信息可以只用于PUSCH和PUCCH,不用于SRS,即SRS仍然采用现有的基于SRS资源集合的功率控制参数配置方式,与TCI状态无关;也可以应用于各种类型的上行信号。
Figure PCTCN2020073819-appb-000005
同样的,网络设备也可以通过MAC CE来激活或更新任意一个TCI状态ID对应的功率控制参数。
其中,在本申请实施例中,一个TCI状态可以包含以下信息中的至少一项:QCL类型,参考信号(例如,可以是参考信号ID),参考服务小区,参考BWP(例如,可以是参考BWP ID)。
例如,QCL类型可以包含终端设备和网络约定的若干种QCL类型之一,例如至少包含以下几种QCL类型之一:
1.QCL type X:空间发送参数(Spatial Tx Parameter)
2.QCL type Y:空间传输滤波器(Spatial Transmission Filter)
3.QCL type Z:天线面板(panel)
其中,前两种用于确定发送波束,第三个用于确定发送所用的天线面板。
例如,终端可以和网络设备约定QCL类型,例如为以上QCL type X,此时TCI状态中不需要QCL类型的指示信息。
例如,参考信号ID可以用于确定作为上行信号的QCL参考的信号,例如用于确 定上行信号的发送波束或者发送panel的参考信号。终端设备可以根据参考信号的发送或接收波束,确定上行信号的发送波束。
例如,参考服务小区和参考BWP ID可以用于确定参考信号ID所指示的参考信号所在的载波和BWP。
其中,在本申请实施例中,该功率控制参数包括以下中的至少一项:用于确定目标接收功率P 0的参数,用于确定路损加权因子a的参数,用于路损测量的参考信号,闭环功率控制进程的索引。
例如,用于确定目标接收功率P 0的参数和用于确定路损加权因子a的参数可以用同一个参数集合来确定(例如前述P0-AlphaSetId对应的一个P0-AlphaSet可以包含这两个参数);
例如,用于路损测量的参考信号可以是SSB或者CSI-RS。
例如,闭环功率控制进程的索引可以是终端和网络设备约定的l的取值中的一个,例如0-1或0-3。
2.终端设备根据为PUSCH配置的目标TCI状态,以及对应关系,确定PUSCH的功率控制参数,其中M个TCI状态包含目标TCI状态。
其中,在本申请实施例中,终端根据目标TCI状态和对应关系,确定与目标TCI状态对应的功率控制参数,作为PUSCH的功率控制参数。
其中,终端可以根据以下方式一来确定目标TCI状态:
(1)根据网络设备发送的RRC信令确定M个TCI状态以及至少一个TCI状态与PUSCH功率控制参数的对应关系;
(2)根据MAC CE从M个TCI状态中激活K个TCI状态用于PUSCH传输,其中K小于等于M。
(3)根据DCI中的TCI状态指示信息从K个TCI状态中确定目标TCI状态,其中TCI状态指示信息的每个指示值对应K个TCI状态中的一个或多个TCI状态。如果网络设备没有发送MAC CE,则TCI状态指示信息用于从M个TCI状态中确定目标TCI状态。
需要说明的是,方式一可以用于调度PUSCH的DCI中包含TCI状态指示信息的情况,例如DCI format 0_1。可选地,DCI与PUSCH之间的时间间隔需要大于或等于一定的门限值。该门限值可以是终端上报的值或者网络设备配置的值。
其中,终端可以根据以下方式二来确定目标TCI状态:
目标TCI状态为MAC CE激活的K个用于PUSCH传输的TCI状态中TCI状态ID最低的TCI状态,或者,为MAC CE激活的用于PUSCH传输的TCI状态中的第一个TCI状态,或者,为TCI状态指示信息中最低的取值(例如,如果信息有3个比特,则为000)所指示的TCI状态,或者,为RRC配置的M个TCI状态中TCI状态ID最 低的TCI状态,或者,为承载DCI的PDCCH所在的CORESET所用的TCI状态。
需要说明的是,方式二可以用于调度PUSCH的DCI中不包含TCI状态指示信息的情况,或者用于DCI与PUSCH之间的时间间隔小于一定门限值的情况。该门限值可以是终端上报的值或者网络设备配置的值。
其中,在本申请实施例中,如果TCI状态与PUSCH功率控制参数的对应关系没有配置给终端,例如,终端没有接收到相应的RRC参数,则终端设备可以将网络设备配置的功率控制参数候选集合中索引最低的功率控制参数确定为PUSCH的功率控制参数。例如,终端设备可以采用PathlossReferenceRS-Id=0对应的路损测量参考信号,采用P0-AlphaSetId=0对应的P0-AlphaSet中的参数确定P0和alpha,采用close loop index=0对应的闭环功率控制进程。
其中,在本申请实施例中,可以对PUSCH的功率控制参数进行以下说明。
例如,如果目标TCI状态所指示的QCL参考信号是一个上行信号(如SRS),则根据本发明确定的PUSCH的功率控制参数与目标TCI状态所指示的QCL参考信号的功率控制参数相同。这里的功率控制参数可以只包含pathloss RS,也可以包含其他功率控制参数。
例如,如果功率控制参数为用于路损测量的下行参考信号,目标TCI状态所指示的QCL参考信号是一个下行信号,则PUSCH的路损测量参考信号与目标TCI状态所指示的QCL参考信号相同。
实施例2:(PUCCH)
1.终端设备根据高层信令确定至少一个TCI状态与PUCCH功率控制参数的对应关系。具体的配置方式参考上述实施例1。
2.终端设备根据为PUCCH配置的目标TCI状态,以及对应关系,确定与目标TCI状态对应的功率控制参数,作为PUCCH的功率控制参数。
作为一种可选的实施例,终端设备可以通过RRC信令确定M个TCI状态,并根据MAC CE激活其中的一个用于PUCCH传输的TCI状态,作为目标TCI状态。其中,MAC CE可以携带目标TCI状态对应的TCI状态ID(称为目标TCI状态ID)。
作为一种可选的实施例,如果终端没有接收到用于激活TCI状态的MAC CE,则目标TCI状态为一个预设的TCI状态,例如,为RRC配置的M个TCI状态中TCI状态ID最低的TCI状态(例如TCI状态ID=0对应的TCI状态)。
作为一种可选的实施例,如果TCI状态与PUCCH功率控制参数的对应关系没有配置给终端,例如,终端没有接收到相应的RRC参数,则终端设备可以将网络设备配置的功率控制参数候选集合中索引最低的功率控制参数确定为PUCCH的功率控制参数。例如,终端设备可以采用PathlossReferenceRS-Id=0对应的路损测量参考信号,采 用P0-SetId=0对应的P0-Set中的参数确定P0,采用close loop index=0对应的闭环功率控制进程。
其中,在本申请实施例中,可以对PUCCH的功率控制参数进行以下说明。
例如,如果目标TCI状态所指示的QCL参考信号是一个上行信号(如SRS),则根据本发明确定的PUCCH的功率控制参数与目标TCI状态所指示的QCL参考信号的功率控制参数相同。这里的功率控制参数可以只包含pathloss RS,也可以包含其他功率控制参数。
例如,如果功率控制参数为用于路损测量的下行参考信号,目标TCI状态所指示的QCL参考信号是一个下行信号,则PUCCH的路损测量参考信号与目标TCI状态所指示的QCL参考信号相同。
作为一种可选的实施例,终端设备可以接收高层信令配置的载波集合,当终端接收到用于激活一个PUCCH传输的目标TCI状态(该TCI状态的ID称为目标TCI状态ID)的MAC CE后,载波集合中的每个载波上的目标BWP中与该PUCCH采用相同PUCCH资源(或者相同的PUCCH资源ID)的PUCCH都采用所激活的目标TCI状态,或者,载波集合中的每个载波上的目标BWP中与该PUCCH采用相同PUCCH资源(或者相同的PUCCH资源ID)的PUCCH都采用目标TCI状态ID来获得目标TCI状态,从而确定自身的功率控制参数。其中,目标BWP为与该PUCCH所在的BWP的BWP ID相同的BWP,或者为每个载波上当前被激活的BWP。
实施例3:(SRS)
1.终端设备根据高层信令确定至少一个TCI状态与SRS功率控制参数的对应关系。具体的配置方式参考实施例1。
2.终端设备根据为SRS配置的目标TCI状态,以及对应关系,确定SRS的功率控制参数,其中至少一个TCI状态包含目标TCI状态。
作为一种可选的实施例,可以采用以下方法之一:
方法1:目标TCI状态为RRC配置的一个用于SRS传输的TCI状态,或者为MAC CE指示的一个用于SRS传输的TCI状态,或者为承载SRS的SRS资源所在的SRS资源集合中的一个预设SRS资源所对应的TCI状态。
其中,MAC CE可以携带目标TCI状态对应的TCI状态ID(称为目标TCI状态ID)。
其中,承载SRS的SRS资源所在的SRS资源集合中的一个预设SRS资源可以是该SRS资源集合中最早传输的SRS资源,或者该SRS资源集合中SRS资源ID最低的SRS资源。终端可以将网络设备为该预设SRS资源配置的TCI状态作为目标TCI状态,从而确定SRS的功率控制参数。
其中,SRS资源集合中的所有SRS资源都采用该预设SRS资源对应的TCI状态作为目标TCI状态,从而确定相同的功率控制参数。
例如,终端设备可以将网络设备为预设SRS资源配置的TCI状态所对应的功率控制参数,作为SRS资源集合中所有SRS资源的功率控制参数。
方法2:上行信号为准持续性SRS,此时目标TCI状态为用于激活SRS的MAC CE所指示的一个用于SRS传输的TCI状态。
方法3:上行信号为非周期性SRS,此时目标TCI状态为用于触发非周期性SRS的DCI所指示的TCI状态。具体的,可以通过DCI中的TCI状态指示信息指示目标TCI状态,也可以通过DCI中的SRS触发信令来指示目标TCI状态。
作为一种可选的实施例,如果TCI状态与SRS功率控制参数的对应关系没有配置给终端,例如,终端没有接收到相应的RRC参数,则终端设备可以将网络设备配置的功率控制参数候选集合中索引最低的功率控制参数确定为SRS的功率控制参数。例如,终端设备可以采用PathlossReferenceRS-Id=0对应的路损测量参考信号,采用P0-AlphaSetId=0对应的P0-AlphaSet中的参数确定P0和alpha,采用close loop index=0对应的闭环功率控制进程。
其中,在本申请实施例中,可以对SRS的功率控制参数进行以下说明,具体实施方式参考实施例2。
作为一种可选的实施例,终端设备可以接收高层信令配置的载波集合,当终端接收到用于激活一个SRS的目标TCI状态(该TCI状态的ID称为目标TCI状态ID)的MAC CE后,载波集合中每个载波上的目标BWP中与承载该SRS的SRS资源采用相同SRS资源ID的SRS资源都采用所激活的目标TCI状态,或者,载波集合的每个载波上的目标BWP中与承载SRS的SRS资源采用相同SRS资源ID的SRS资源都采用目标TCI状态ID来获得自身的目标TCI状态,从而确定自身的功率控制参数。目标BWP为与该SRS所在的BWP的BWP ID相同的BWP,或者为每个载波上当前被激活的BWP。
通过上述实施例,终端可以根据网络设备配置的TCI状态来确定功率控制参数,而且不同的上行信号类型可以采用不同的功率控制参数确定方式,从而支持用不同的发送波束发送上行信号时,可以确定不同的功率控制参数,以得到适合当前传输的发送功率。
