1、关于多TRP传输技术
3GPP Rel-15提出了多发送接收点/多天线面板(multi-TRP/multi-panel)的场景,多TRP传输可以增加传输的可靠性及吞吐量性能,例如UE可以接收来自于多个TRP的相同数据或不同数据。目前定义了Type I的多天线面板码本,包括如图2所示的三种多TRP传输场景:
图2中的(1)为同一TRP内的多天线面板的传输场景;
图2中的(2)为多TRP间的多TRP/panel传输,理想回程线路(backhaul)的传输场景;
图2中的(3)为多TRP间的多TRP/panel传输,非理想回程线路的传输场景。
多TRP的传输方案可以有如下几种:
1)多TRP共同发送一个PDSCH
■每个TRP发送一个传输块(transport block,TB)的不同层;
■每个TRP发送一个TB,不同的TRP发送不同的TB;
■各TRP以重复(repetition on)的方式发送同一个TB;
2)多TRP发送多个PDSCH,每个TRP发送一个PDSCH
在现有的信道状态信息(channel state information,CSI)框架中,CSI报告与CSI资源的关系可以配置为:
1)周期CSI报告(P-CSI):仅用于周期CSI资源的报告,且仅能在PUCCH上传输;
2)半持续CSI报告(SP-CSI):可用于周期/半持续CSI资源的报告,在PUCCH或PUSCH上传输;
3)非周期CSI报告(AP-CSI):可用于周期/半持续/非周期CSI资源的报告,且仅在PUSCH上传输;
CSI报告包含CSI-RS索引(channel state information reference signal index,CRI)、SSB块资源索引(synchronization signal block resource index,SSBRI)、层1(L1)指示、层1-参考信号接收功率(L1reference signal received power,L1-RSRP)、层1-信号加干扰噪声比(L1 signal to interference plus noise ratio,L1-SINR)、预编码秩指示(recoding matrix indicator,PMI)、信道质量指示(channel quality indicator,CQI)、秩指示(rank indicator,RI)中的至少一项。波束报告作为CSI报告的一种格式,包含但不限于CRI、SSBRI、层1指示、L1-RSRP、L1-SINR。
在R15/16中,多TRP间多TRP/panel传输方案下波束报告方案有如下两种:
1)基于组(group based)的波束报告
波束报告中包含两个CRI/SSBRI及其对应的L1-RSRP/L1-SINR,其中两个CRI/SSBRI所指示的发送波束需满足被UE同时接收的要求。
2)不基于组(non-group based)的波束报告
波束报告中最多包含N(N=1/2/4)个L1-RSRP/L1-SINR最好的CRI/SSBRI,无需满足被UE同时接收的要求。
3GPP Rel-16标准化了多发送接收点/多天线面板(multi-TRP/multi-panel)场景, 可以增加传输的可靠性及吞吐量性能,例如UE可以接收来自于多个TRP的相同数据或不同数据。多TRP间可以分为理想回程线路(ideal backhaul)和非理想回程线路(non-ideal backhaul)。非理想回程线路时,多TRP间交互信息存在较大时延,比较适合独立调度,ACK/NACK和CSI报告分别向各TRP反馈。通常适用于多DCI调度,即每个TRP发送各自的PDCCH,每个PDCCH调度各自的PDSCH,为UE配置的多个控制资源集(CORESET)关联到不同的RRC参数控制资源集池索引(CORESETPoolIndex),对应不同的TRP。多个下行控制信息(downlink control information,DCI)调度的多个PDSCH在时频资源上可能是不重叠、部分重叠、完全重叠的。在重叠的时频资源上,每个TRP根据各自的信道进行独立预编码,UE按照非相干联合传输(non-coherent joint transmission,NCJT)的方式接收属于多个PDSCH的多层数据流。
理想回程线路时,多TRP之间可以实时交互调度信息和UE的反馈信息,除了可以通过上述的多DCI调度多PDSCH,还可以单DCI调度PDSCH,包括如下一些传输方案:
空分复用(space division multiplexing,SDM):同一TB(传输块)的不同数据层来自不同TRP的NCJT传输。
频分复用(frequency division multiplexing,FDM):同一TB同一RV映射的不同频域资源发自不同TRP或同一TB的不同冗余版本(redundancy version,RV)映射到不同频域资源并发自不同TRP。
时分复用(time division multiplexing,TDM):同一TB的不同RV的多次重复来自不同TRP,例如在一个时隙内的重复,或多个时隙的重复。
此时ACK/NACK反馈和CSI报告可以向任意一个TRP进行反馈。
R17中将对增强多TRP间多TRP/panel同时传输的波束报告方法做进一步的定义与阐述。
在3GPP R17支持mTRP场景中的PDCCH重复(repetition)传输方案,该方案只能应用在单DCI调度中。
RRC信令显式配置PDCCH所在的两个SS set(search space set)相互关联。
两个SS set不限制是关联到同一个或不同的CORESET。不限制两个SS set所关联的CORESET的TCI state是否相同或不同。
UE不期望第三个监听的SS set关联到上述两个相互关联的SS set中任意一个。
两个相互关联的SS set具有相同的周期、偏移(offset)、持续时长(duration)、监听时机(monitoring occasion)数量、AL等。
一个SS set的第n个监听时机(monitoring occasion)关联另一个SS set的第n个monitoring occasion,两个PDCCH候选(candidate)具有相同的候选索引(candidate index)。
不支持inter-slot PDCCH repetition。
上述SS set仅可以是用户设备专用搜索空间(UE-specific search space,USS)和Type3公共搜索空间(common search space,CSS)。
RRC参数recoverySearchSpaceId所配置的SS set不与其它SS set相关联。
在3GPP R17支持了多TRP场景中一个DCI动态调度时分复用(TDM)方式的PUSCH repetition传输方案。
对于每个PUSCH重复分别使用对应不同TRP的多个发送波束(spatial relation)进行发送,以提高PUSCH传输的可靠性。
对于Type A(slot-level)的PUSCH重复来说,一次PUSCH重复是指每个时隙内的一个PUSCH传输时机;对于Type B的PUSCH重复,一次PUSCH重复则为名义重复(nominal repetition)。
DCI中可以指示两套波束(spatial relation)、预编码矩阵、功控参数等,并且在DCI中增加一个2bit的新指示域以支持在STRP和MTRP之间动态切换,以及灵活交换PUSCH重复发送波束的先后顺序。
各次PUSCH重复与波束的映射关系可由RRC参数配置为轮流映射(cyclic mapping)和连续映射(sequential mapping)。
在3GPP R17支持了多TRP场景中的PUCCH repetition的传输方案。
网络给PUCCH资源或PUCCH group激活两个波束,则该PUCCH各次重复采用两个波束发送。
各次PUCCH重复与波束的映射关系可由RRC参数配置为轮流映射和连续映射。
在3GPP R17支持PDCCH系统帧号(system frame number,SFN)和PDSCH SFN传输方案。
RRC信令配置PDCCH或PDSCH的SFN传输方案。其中,PDCCH只能是在USS或Type3CSS上监听。
MAC CE命令可以激活2个TCI state,用于PDCCH使用2个波束进行SFN传输。
SFN传输方案中包括scheme1(UE高级接收机)和预补偿。其中,SFN PDCCH(scheme1)可以调度STRP PDSCH(UE能力),SFN PDCCH(scheme1,预补偿)可以调度SFN PDSCH(scheme1or预补偿,两个模式一一对应调度),STRP PDCCH(仅与USS或CSS type3相关联)可以调度STRP PDSCHorSFN PDSCH(scheme1+预补偿),STRP PDCCH与CSS或CSS+USS相关联可以调度STRP PDSCH。但是,SFN PDCCH不能调度3GPP R16中的PDSCH传输方案。
需要说明的是,本申请中提及的波束信息,也可以称为:波束的标识信息、空间关系(spatial relation)信息、空域发送滤波器(spatial domain transmission filter)信息、空域接收滤波器(spatial domain reception filter)信息、空域滤波器(spatial filter)信息、传输配置指示状态(TCI state)信息、准共址(QCL)信息、QCL参数等。其中,下行波束信息通常可使用TCI state信息或QCL信息表示。上行波束信息通常可使用TCI state信息或spatial relation信息表示。
下面结合附图,通过一些实施例及其应用场景对本申请实施例提供的信息指示方法进行详细地说明。
如图3所示,本申请实施例提供一种信息指示方法,该方法应用于如图1所示的无线通信系统,该方法可以由UE和网络侧设备执行。该方法包括下述的步骤201-步骤203。
步骤201、网络侧设备向UE发送第一指示信息。
其中,上述第一指示信息可以用于指示网络侧设备的空域相关信息发生变化。
步骤202、UE从网络侧设备接收第一指示信息。
步骤203、UE根据第一指示信息,执行或不执行以下至少一项操作:
监听与第一指示信息相关的资源;
对与第一指示信息相关的信号或波束测量和测量结果上报;
接收与第一指示信息相关的下行数据。
本申请实施例中,在网络侧设备的空域相关信息发生变化时,网络侧设备可以向终端发送上述第一指示信息,从而在UE接收到该第一指示信息之后,终端可以根据该第一指示信息,准确地执行或不执行与网络侧设备相关的操作。
需要说明的是,本申请实施例中,上述网络侧设备的空域相关信息发生变化可以为TRP的状态即将发生变化。可选地,TRP的状态即将发生变化可以包括以下至少一项:网络侧设备即将关闭某个TRP,网络侧设备即将开启某个TRP,网络侧设备即将从一个TRP切换至另一个TRP等。即,上述第一指示信息可以通过指示空域相关信息发生变化,指示网络侧设备即将关闭某个TRP,网络侧设备即将开启某个TRP,网络侧设备即将从一个TRP切换至另一个TRP中的至少一项。
在一种可能的实施方式中,上述第一指示信息中可以包括一个域,该域用于指示该第一指示信息指示的是网络侧设备关闭某个TRP,网络侧设备开启某个TRP,还是网络侧设备从一个TRP切换至另一个TRP。在另一种可能的实施方式中,可以协议预定义该第一指示信息指示的是网络侧设备关闭某个TRP,网络侧设备开启某个TRP,还是网络侧设备从一个TRP切换至另一个TRP。
当负载较低时,网络侧设备可以通过关闭某个TRP,进行节能,如此与即将关闭的TRP相关的UE执行测量和测量结果上报等行为都会受到影响。本申请实施例中,网络侧设备可以通过上述第一指示信息,将即将关闭的TRP相关的空域相关信息等通知UE,从而可以避免UE执行不必要的测量和测量结果上报等操作。
其中,当网络侧关闭某个TRP时,相当于进入TRP休眠(dormancy)状态。
需要说明的是,网络侧设备尽量不会关闭最小的(lowest)控制资源集(control resource set,CORESET)标识(identifier,ID)所关联的CORESET所对应的TRP,以保证UE能找到合适的准共址(quasi co-location,QCL)资源。如果网络侧设备即将关闭最小的CORESET ID指示的CORESET所对应的TRP,那么在发送数据时,网络侧设备(例如gNB)采用处于开启状态的TRP所对应的TCI state,发送下行数据,并通过媒体接入控制(medium access control,MAC)控制单元(control element,CE)或者下行控制信息(downlink control information,DCI)指示更新下行的TCI state。从而UE根据网络侧设备指示的处于开启状态的TRP对应的TCI state,接收物理下行控制信道(physical downlink control channel,PDCCH)重复(repetition)。如,在Multi-TRP场景下,存在TRP0和TRP1,当网络侧设备进入节能状态之后,预计关闭TRP0,则网络侧设备可以通过DCI告知UE,TRP0的TCI State即将更改为TRP1的TCI State,所以后续UE可以根据TRP1的TCI State接收下行数据。
可选地,本申请实施例中,上述第一指示信息可以包括以下至少一项:
附加(additional)物理小区标识符(physical cell identifier,PCI),附加PCI与UE的服务小区PCI不同;
波束索引;
波束组索引;
波束集索引;
特殊的(special)传输配置指示状态(transmission configuration indicator state,TCI state);
特定的(specific)TCI state;
默认的(default)TCI state;
搜索空间集组(search space set group,SSSG)切换指示,该SSSG切换指示用于指示SSSG的切换。
可选地,本申请实施例中,上述附加PCI的数量可以为一个或多个,每个附加PCI可以与以下任一项存在关联关系:
控制资源集池索引(coresetPoolIndex);
TCI state;
TCI state组(group)。
需要说明的是,本申请实施例中,coresetPoolIndex,TCI state或TCI state组可以对应一个TRP,因此,在UE接收到第一指示信息之后,UE可以根据附加PCI关联的coresetPoolIndex,TCI state或TCI state组,确定是哪个TRP的状态发生变化。
可选地,本申请实施例中,网络侧设备可以通过TCI State配置中的TCI State组标识(identifier,ID),对为UE配置的TCI State进行分组。
可选地,本申请实施例中,上述关联关系可以由网络侧设备通过无线资源控制(radio resource control,RRC)信令配置。例如,上述关联关系可以由网络侧设备通过RRC信令提前配置给UE。
可选地,本申请实施例中,一个波束组包含的波束满足以下任意一项:
由网络侧设备通过RRC信令向UE预配置;
由网络侧设备通过MAC CE更改。
可以理解,上述波束组可以为波束组索引指示的波束组。
在一些实施例中,上述波束索引,波束组索引和波束集索引可以通过其编号直接指示,也可以通过位图(bitmap)的形式指示。例如,不同的波束组分别对应不同的TRP,即beam group 0与TRP0对应,beam group 1与TRP1对应,则bitmap有两个位,分别对应了beam group 0和beam group 1,当bitmap显示为10时,表示TRP0开启,TRP1被关闭;当bitmap显示为11时,表示TRP0和TRP1均开启。
本申请实施例中,不同的波束(beam)或波束组(beam group)对应不同的TRP。网络侧设备可以通过该波束的波束索引指示该波束对应的TRP的状态发生变化,或者,通过该波束组的波束组索引指示该波束组对应的TRP的状态发生变化。例如,网络侧设备通过波束索引或波束组索引指示该波束或波束组对应的TRP即将被关闭。
需要说明的是,本申请实施例是以网络侧设备即将关闭TRP为例对本申请的信息指示方法进行示例性说明的,对于网络侧即将开启TRP和/或从一个TRP切换至另一个TRP,其实现方式与网络侧设备即将关闭TRP的实现方式相同。为避免重复,本申请实施例不予赘述。
本申请实施例中,属于同一个TRP的波束可以放在一个波束集(beam set)中,或者一个面板(panel)对应的波束放在一个波束集中。如此,当TRP的状态发生变化时,可以通过第一指示信息中的波束集索引,指示该波束集索引指示的波束集对应的TRP的状态发生变化。例如,网络侧设备可以通过第一指示信息中的波束集索引指示去激活该波束集,从而指示关闭该波束集对应的TRP。
需要说明的是,本申请实施例中,去激活也可以被描述为去使能(disable),使无效。具体可以根据实际使用需求确定,本申请实施例不作限定。
可选地,本申请实施例中,可以通过波束集索引对应的bitmap指示该波束集发生变化,从而指示该波束集对应的TRP状态发生变化,如此可以节省第一指示信息中指示网络侧设备的空相关信息发生变化所使用的比特数。
本申请实施例中,在第一指示信息包括特殊的TCI State,特定的TCI State,或者默认的TCI state的情况下,第一指示信息可以指示切换至该特殊的TCI State,特定的TCI State,或者默认的TCI state,即默认进入了TRP休眠(dormancy)状态。如此,UE可以按照该特殊的TCI State,特定的TCI State,或者默认的TCI state进行下行接收和上行传输等操作。即,UE可以通过该特殊的TCI State,特定的TCI State,或者默认的TCI state对应的TRP,进行下行接收和上行传输等操作,而其余TCI state对应的TRP则无需再进行相关的测量和测量结果上报等行为。
需要说明的是,在第一指示信息包括特殊的TCI State,特定的TCI State,或者默认的TCI state的情况下,默认关闭编号为非0的TRP。
可选地,本申请实施例中,不同SSSG由网络侧设备通过RRC信令关联到不同的控制资源集池索引,TCI state,或TCI state组。而不同的控制资源集池索引,TCI state,或TCI state组对应不同的TRP,因此,不同的SSSG与不同的TRP具有关联关系,即不同的SSSG可以对应不同的TRP,也可以称为不同的SSSG与不同的TRP绑定,从而网络侧设备可以通过SSSG切换指示,指示SSSG的切换,进而指示TRP切换。
以不同SSSG关联不同的控制资源集池索引(coresetPoolIndex)为例,SSSG0={ss0,ss1,ss2,ss3}与coresetPoolIndex{0,1}相关联,SSSG1={ss0,ss1}与coresetPoolIndex{0}相关联。
示例性地,假设SSSG1和TRP1绑定,SSSG2和TRP1、TRP2绑定,并且默认SSSG1所对应的TRP1永远不会被关闭,即TRP1为默认一直开启的TRP。那么,当第一指示信息指示从SSSG2切换到SSSG1时,可以指示TRP2即将被关闭。
可选地,本申请实施例中,上述第一指示信息可以用于指示以下至少一项:
更改待去激活的控制资源集池索引(coresetPoolIndex)所关联的TCI state;
关闭搜索空间关联配置;
开启搜索空间关联配置;
指示网络侧设备为单发送接收点(single transmission reception point,STRP或S-TRP)或者多发送接收点(multiple transmission reception point,MTRP或M-TRP),示例性地,可以通过DCI中的2比特(bit)指示网络侧设备为STRP还是MTRP;
去激活第一物理上行控制信道(physical uplink control channel,PUCCH)的空域相关信息,该第一PUCCH为待去激活的控制资源集池索引,TCI state,或TCI state组所关联的PUCCH。
可选地,本申请实施例中,上述搜索空间关联配置为Searchspacelinking。其中,Searchspacelinking是RRC信令中的一个域,如果在RRC信令中配置了Searchspacelinking,则默认为网络侧设备处于MTRP场景。如此,当网络侧设备进入节能模式时,需要从MTRP场景切换为STRP场景,那么需要取消searchspacelinking的配置,因此网络侧设备可以通过上述第一指示信息取消Searchspacelinking配置,即取消两个搜索空间的关联关系。相应的,当网络侧设备退出节能模式时,需要从STRP场景切换为MTRP场景时,网络侧设备可以通过第一指示信息指示Searchspacelinking, 即增加两个搜索空间的关联关系。
可选地,上述第一指示信息可以承载于MAC CE,组公共(group common)DCI,UE特定(specific)DCI,或者RRC信令。
可选地,本申请实施例中,上述第一指示信息的生效时刻可以存在三种情况,分别为下述的情况一、情况二和情况三。下面分别对这三种情况进行示例性地说明。
情况一:在第一指示信息包含在第二指示信息之内的情况下,第一指示信息的生效时刻与第二指示信息的生效时刻相同。
其中,第二指示信息为网络侧设备的模式切换的指示信息。
情况二:在第一指示信息包含于第二指示信息(网络侧设备的模式切换的指示信息)之外的情况下,第一指示信息的生效时刻为以下任意一项:
第一指示信息所在时隙之后的第X个时隙(slot),X为正整数;

第一指示信息所在时隙之后的第X个帧(frame);
距离第一指示信息所在时隙最近的可用生效位置;

第二指示信息所在时隙之后的第Y个子帧;
第二指示信息所在时隙之后的第Y个帧;
第一定时器超时的时刻,第一定时器在UE接收到第一指示信息时启动。
可以理解,上述第一定时器可以为用于给第一指示信息的生效时刻计时的定时器,当UE接收到该第一指示信息时,第一定时器启动,当第一定时器超时,第一指示信息生效。
可选地,本申请实施例中,上述可用生效位置可以为网络侧设备预先指示的,或者协议预定义(规定)的。

可以理解,上述与第一指示信息相关的资源可以包括上述SSSG切换指示所指示的SSSG关联的coresetPoolIndex所对应的TRP相关的资源,包括与该TRP相关的PDCCH,下行参考信号等等。
另外,上述候选PDCCH与附加PCI对应的SSB冲突是指候选PDCCH所占用的资源与传输附加PCI对应的SSB的资源冲突。
可选地,在一些实施例中,上述UE根据第一指示信息,执行或不执行测量与第一指示信息相关的信号或波束,并进行测量结果上报,包括以下至少一项:

需要说明的是,上述PUCCH重复与附加PCI对应的SSB冲突是指:传输PUCCH重复的资源与传输附加PCI对应的SSB的资源冲突。
本申请实施例中,在波束索引,波束组索引或波束集索引对应的TRP关闭的情况下,UE可以取消对第一波束对应方向的参考信号的测量和测量结果上报,和/或,取消对第一波束的测量和测量结果上报。在波束索引,波束组索引或波束集索引对应的TRP开启的情况下,UE可以开启对第一波束对应方向的参考信号的测量和测量结果上报,和/或,开启对第一波束的测量和测量结果上报。

默认的波束;
特殊的波束;
特定的搜索空间集组(SSSG)。
可选地,本申请实施例中,上述默认联合HARQ-ACK反馈切换为单独HARQ-ACK反馈可以为协议预定义的。
示例性地,假设SSSG1和TRP1绑定,SSSG2与TRP1和TRP2绑定,默认SSSG1所对应的TRP1不会关闭,即TRP1是默认一直开启的TRP。当第一指示信息指示从SSSG2切换到SSSG1时,TRP2将被关闭。在协议规定从MTRP场景切换到STRP场景的情况下,联合HARQ-ACK反馈切换为单独HARQ-ACK反馈,此时UE仅需上报 TRP1所对应的HARQ-ACK码本。
可选地,本申请实施例中,在配置的HARQ-ACK反馈方式为联合HARQ-ACK反馈的情况下,若第一指示信息指示网络侧设备即将切换至特定的波束、特殊的波束、默认的波束,统一的(unified)波束、或搜索空间(search space)对应的TRP时,默认去使能(disable)联合HARQ-ACK反馈,即更改为单独HARQ-ACK反馈。
可选地,本申请实施例中,在配置的HARQ-ACK反馈方式为单独HARQ-ACK反馈的情况下,取消上报待去激活的控制资源集池索引,TCI state,或TCI state组所对应的下行调度的HARQ-ACK反馈信息。具体地,取消上报待去激活的控制资源集池索引,TCI state,或TCI state组所对应的TRP的HARQ-ACK反馈信息。
可选地,在一些实施例中,上述UE根据第一指示信息,执行或不执行接收与第一指示信息相关的下行数据,包括:
UE按照根据第一指示信息指示的TCI state或波束方向接收下行数据。
其中,上述第一指示信息指示的TCI state可以为更改后的TCI state,第一指示信息指示的波束方向可以为特殊的TCI state的波束方向,特有的TCI state的波束方向,或者默认的TCI state的波束方向。
本申请实施例中,由于网络侧设备的空域相关信息与网络侧设备的状态相关联,且第一指示信息指示网络侧设备的空域相关信息发生变化,因此在UE接收到上述第一指示信息之后,UE可以根据变更后的空域相关信息,确定网络侧设备变化后的状态,从而可以根据网络侧设备变化后的状态,准确地执行或不执行与网络侧设备相关的操作,进而可以避免执行不必要的操作。
下面再结合具体的实施例对本申请提供的信息指示方法进行示例性地说明。
实施例1:
假设网络侧设备通过RRC信令向UE配置了不同的SSSG与不同的CORESETPoolIndex相关联,如:
SSSG0={SS0,SS1},SSSG0包含了SS0,SS1,对应了CORESETPoolIndex{0},其中,
SS0关联的controlResourceSetId是CORESET0,CORESET0关联的coresetPoolIndex是0,SS1关联的controlResourceSetId是CORESET1,CORESET1关联的coresetPoolIndex是0;
SSSG1={SS0,SS1,SS2,SS3},SSSG0包含了SS0至SS3,对应了CORESETPoolIndex{0,1},其中,
SS0关联的controlResourceSetId是CORESET0,CORESET0关联的coresetPoolIndex是0,SS1关联的controlResourceSetId是CORESET1,CORESET1关联的coresetPoolIndex是0,SS2关联的controlResourceSetId是CORESET2,CORESET2关联的coresetPoolIndex是1,SS3关联的controlResourceSetId是CORESET3,CORESET3关联的coresetPoolIndex是1。
当网络整体负载较低时,网络侧设备给UE发送第一指示信息(例如,DCI 2_0),显示指示SSSG从SSSG1切换到SSSG0,则UE默认CORESETPoolIndex为1的CORESETPoolIndex所对应的TRP被关闭,则与该TRP相关的参考信号无需进一步测量和测量结果上报,同时也取消该TRP对应的HARQ-ACK反馈。
实施例2:
网络侧设备在TCI State配置中增加了一个TCI State group Id,从而可以给配置的TCI State进行分组。假设TCI State group 0与TRP A关联,TCI State group1与TRP B相关联。当网络侧设备准备进入节能状态时,准备关闭TRP A以进行节能,网络侧设备可以向UE发送第一指示信息,用bitmap的形式指示TCI State group 0无效,从而UE默认暂停与TRP A相关的测量和测量结果上报等操作。
