本申请涉及无线通信网络,例如涉及一种信道测量方法和装置。
在无线通信领域,路径损耗会随着载频的升高而增加,特别是在高频通信中,路径损耗问题对性能的影响会更加突出。为了保证覆盖,一般会使用多阵子阵列天线以获得波束赋型增益,用波束赋型增益来弥补路径损耗的影响。而为了获得波束增益,需要根据用户终端所处的信道选择与用户终端信道匹配的最佳波束。
第五代移动通信(5th Generation,5G)的新无线接入技术(New Radio Access Technology,NR)的发布(Release)15版本中采用的是基于参考信号接收功率(Reference signal received power,RSRP)选择波束的方法,即把接收功率最大的波束作为用户的发送或接收波束。而这种方法没有考虑同频干扰的影响,所以在干扰影响较大的场景,基于RSRP的方法并不能很好地准确选择波束。

下文中将结合附图对本申请的实施例进行详细说明。
在无线通信技术中,提出了通过多阵子阵列天线进行多波束赋型,从而提高波束增益,弥补路径损耗的方案。如图1所示,图1为一实施例提供的多波束传输示意图,在图1中,基站和终端之间分别通过多阵子阵列天线实现了多波束。为了获得波束增益,需要根据终端所处的信道选择与终端信道匹配的最佳波束。采用的波束选择方法是基于RSRP进行选择的,但由于基站和终端进行了多波束赋型,同频的其他波束会对所需选择的波束产生干扰,从而影响波束的选择。因此就需要对波束的信道信息和干扰信息进行准确地测量,从而根据测量结果实现波束的准确选择。
图2为一实施例提供的一种信道测量方法的流程图,如图2所示,本实施例提供的方法包括如下步骤。
步骤S2010,配置测量资源信息,测量资源信息用于获取信道状态信息,其中,测量资源信息包括N个信道测量资源信息和M个干扰测量资源信息,N和M为正整数。
本实施例提供的信道测量方法应用于无线通信***中的基站设备,简称基站。基站为终端分配各种传输资源,以及向终端发送各种配置信息,以使终端确定传输所使用的资源和所需执行的各种测量或传输指令。
在基站和终端通过多阵子阵列天线实现多波束赋型时,终端需要对基站赋型的多个波束进行测量,并向基站传输测量到的各波束的状态,从而使基站选 择增益最大的波束作为最佳波束与终端建立信道进行数据传输。终端对各波束的RSRP进行测量并反馈,也即将接收功率最大的波束作为终端所使用的的波束,但这样没有考虑到同频的其他波束的干扰,从而可能影响波束的选择。
为了解决上述问题,在本实施例中,基站配置测量资源信息,测量资源信息用于获取信道状态信息。其中,测量资源信息包括N个信道测量资源(Channel Measurement Resource,CMR)信息和M个干扰测量资源(Interference Measurement Resource,IMR)信息,N和M为正整数。基站在一个报告配置(report config)或报告设置(reporting setting)中配置测量资源信息。其中N个CMR信息用于使终端对各波束的信道状态进行测量,M个IMR信息用于使终端对各波束所受到的干扰进行测量。
CMR信息(CMR setting或者CMR config)包括信道测量资源集合(CMR set)和/或信道测量资源子集合(CMR sub set),一个信道测量资源集合包括至少一个信道测量资源子集合,一个信道测量资源集合包括至少一个信道测量资源,一个信道测量资源子集合包括至少一个信道测量资源。其中,信道测量资源表示用于信道测量的参考信号资源,包括但不限于信道状态信息-参考信号(Channel State Information-Reference Signal,CSI-RS)资源、同步信号块(Synchronization Signals Block,SSB)资源、物理广播信道(Physical Broadcast Channel,PBCH)资源、同步广播块/物理广播信道(SSB/PBCH)资源,上行探测参考信号(Sounding reference signal,SRS)资源。其中CSI-RS资源主要是指非零功率信道状态信息-参考信号(Non Zero Power Channel State Information-Reference Signal,NZP-CSI-RS)资源。当信道测量资源集合只包括一个信道测量资源子集合时,信道测量资源信息为信道测量资源集合,否则可以是信道测量资源子集合。
在本申请一实施例中,每个信道测量资源子集合内的信道测量资源具有相同的空间特性,和/或不同信道测量资源子集合间的信道测量资源具有不同的空间特性。
一个具体的信道测量资源配置方法如下:第l个信道测量资源集合根据预定的方式,比如空间特性分成Kl个信道测量资源子集合,Kl为正整数,l=1,…,N。其中,信道测量资源子集合中包括至少一个信道测量资源,信道测量资源子集合内包括的信道测量资源有相同的空间特性,而不同信道测量资源子集合间的信道测量资源有不同的空间特性。比如将一个信道测量资源集合分成K个子集合,第i个信道测量资源子集合包括Li个信道测量资源,其中第Li个信道测量资源子集合里的信道测量资源都有相同的空间特性,而第Li个信道测量资源子集合里的一个信道测量资源和第Lj个信道测量资源子集合里的一个信道测量 资源有不同的空间特性,i,j=1,…,K,且i不等于j。这里,每个信道测量资源集合包含的信道测量资源子集合的数目可以不同,也可以相同,每个信道测量资源子集合包含的信道测量资源数目也可以相同或者不同。这里还可以根据高层信令配置信道测量资源集合中的信道测量资源子集合。
信道测量资源集合和/或信道测量资源子集合包含的信道测量资源标识(Identify,ID)是统一排序的或者整体排序的,所以信道测量资源集合和/或信道测量资源子集合包含的信道测量资源ID是唯一编号的,不会有重复的ID。
IMR信息(IMR setting或者IMR config)包括干扰测量资源集合(IMR set)、干扰测量资源子集合(IMR sub set)、干扰测量资源子子集合(IMR sub sub set)中的至少一种。一个干扰测量资源集合包括至少一个干扰测量资源子集合,一个干扰测量资源集合包括至少一个干扰测量资源,一个干扰测量资源子集合包括至少一个干扰测量资源子子集合,一个干扰测量资源子子集合包括至少一个干扰测量资源。其中,干扰测量资源表示用于干扰测量的参考信号资源,包括但不限于用于测量干扰的非零功率信道状态信息-参考信号(Non Zero Power Channel State Information-Reference Signal,NZP-CSI-RS)资源,信道状态信息干扰测量(Channel State Information-Interference Measurement,CSI-IM)资源,零功率信道状态参考信号(Zero Power Channel State Information-Reference Signal,ZP-CSI-RS)资源。其中,NZP-CSI-RS干扰测量资源中会配置序列资源即配置测量参考信号,根据NZP-CSI-RS干扰测量资源中的测量参考信号得到干扰的功率。CSI-IM干扰测量资源中不会配置序列资源即也不配置测量参考信号,CSI-IM干扰测量资源上接收的功率即为干扰的功率,一般来说,也没有准共位置之类的参数配置。例如:IMR信息包括M个干扰测量资源集合,M个信息干扰测量资源集合包括的所有干扰测量资源子集合的个数之和为M1,和/或,M个干扰测量资源集合包括的所有干扰测量资源子子集合的个数之和为M2。那么M1和/或M2大于1。当干扰测量资源集合只包括一个干扰测量资源子集合时,干扰测量资源信息为干扰测量资源集合,否则可以是干扰测量资源子集合。如果干扰测量资源子集合被分成了干扰测量资源子子集合,那么干扰测量资源信息为干扰测量资源子子集合。
在本申请一实施例中,每个干扰测量资源子集合内的干扰测量资源具有相同的空间特性,和/或不同干扰测量资源子集合间的干扰测量资源具有不同的空间特性。
一个具体的干扰测量资源配置方法如下:干扰测量资源信息包括干扰测量资源集合和/或干扰测量资源子集合和/或干扰测量资源子子集合;当干扰测量资源信息为干扰测量资源集合时,第l个干扰测量资源集合根据空间特性分成Ol 个干扰测量资源子集合,Ol为正整数,l=1,…,M。其中,干扰测量资源子集合中包括至少一个干扰测量资源,干扰测量资源子集合内包括的干扰测量资源有相同的空间特性,而不同干扰测量资源子集合间的干扰测量资源有不同的空间特性。比如将这个干扰测量资源集合分成O个子集合,第i个干扰测量资源子集合包括Li个IMR,其中第Li个干扰测量资源子集合里的干扰测量资源都有相同的空间特性,而第Li个干扰测量资源子集合里的一个干扰测量资源和第Lj个干扰测量资源子集合里的一个干扰测量资源有不同的空间特性,i,j=1,…,K,且i不等于j。这里,每个干扰测量资源集合保护的干扰测量资源子集合的数目可以不同,也可以相同,干扰测量资源子集合可以分成至少一个干扰测量资源子子集合。
干扰测量资源集合和/或干扰测量资源子集合包含的干扰测量资源ID是统一排序的或者整体排序的,所以干扰测量资源集合和/或干扰测量资源子集合包含的干扰测量资源ID是唯一编号的,不会有重复的ID。
例如:N个信道测量资源信息包括以下之一的具体配置:A1:N个信道测量资源集合,每个信道测量资源集合包括至少一个信道测量资源,每个信道测量资源集合只有一个信道测量资源子集合。A2:N=1个信道测量资源集合,每个信道测量资源集合被分成K个信道测量资源子集合,每个信道测量资源子集合包括至少一个信道测量资源子子集合。A3:N>1个信道测量资源集合,第i个信道测量资源集合被分成Ki个信道测量资源子集合,每个信道测量资源子集合包括至少一个信道测量资源,i=1,…,N。

在配置了测量资源信息后,基站即可向终端发送测量资源信息。基站可以通过任一种下行控制信道向终端发送测量资源信息。
当终端接收到测量资源信息后,即可根据测量资源信息中包括的N个信道测量资源信息和M个干扰测量资源信息分别对信道和干扰进行测量。
终端接收基站配置的信道测量资源信息和干扰测量资源信息,并获取信道测量资源信息和干扰测量资源信息的关联信息,并用信道测量资源信息和干扰测量资源信息以及它们的关联关系计算信道状态信息。比如用第i个信道测量资源子集合的信道测量资源和第j个干扰测量资源子集合的干扰测量资源计算信道状态信息,其中,第i个信道测量资源子集合(集合)和第j个干扰测量资源子集合(集合)具有关联关系,i=1,…,N,j=1,…,M,N和M分别为信道测量资源子集合(集合)和干扰测量资源子集合(集合)的个数。
可选地,基站在发送测量资源信息后,还可以接收终端发送的信道状态信息,信道状态信息包括信道相关参数和/或干扰相关参数。当基站接收到终端发送的信道状态信息,即可确定基站发出的各波束对于终端的信道状态和干扰情况,从而基站可以选择出最优波束与终端建立通信连接实现数据传输。
基站接收到终端发送的测量到的各种参数,即信道状态信息,信道状态信息包括信道相关参数和/或干扰相关参数。其中信道相关参数是终端响应于信道测量资源而测量出的参数,干扰相关参数是终端响应于干扰测量资源而测量出的参数。

比如,信道测量资源信息的重复参数取值为on,那么与之关联的干扰测量资源信息的重复参数取值为on。例如,根据信道测量资源子集合的重复参数取 值确定干扰测量资源子集合和/或干扰测量资源子子集合的重复参数取值;根据信道测量资源的重复参数取值确定干扰测量资源子集合和/或干扰测量资源子子集合的重复参数取值。
由于基站在向终端发送测量资源信息时,并不知道终端需要传输的信道状态信息的总比特数目,因此基站无法准确调度上行资源。另外,终端在传输信道状态信息时,还需要向基站传输除了信道相关参数和干扰相关参数外的信道状态信息(Channel State Information,CSI)相关的参数,混合自动重传(Hybrid automatic repeat request,HARQ)等相关参数。其中信道相关参数和干扰相关参数外的CSI(在本文中把信道相关参数和干扰相关参数外的CSI参数统称为信道质量相关参数)包括但不限于以下至少之一,信道质量指示(Channel Quality Indicator,CQI),预编码矩阵指示(precoding matrix indicator,PMI),信道状态信息参考信号资源指示(CSI-RS resource indicator,CRI),层指示(layer indicator,LI),秩指示(rank indicator,RI)。当终端在完成信道状态信息的检测后,当上行资源无法传输所有信道状态信息时,需要对部分信道状态信息进行舍弃。
那么就需要对信道状态信息进行优先级排序,其中CSI的相关参数的优先级包括以下至少之一:
IQI的优先级不高于RSRP的优先级。
IMRI的优先级不高于CRI或SSBRI的优先级。
IMRI的优先级不低于RI的优先级。
IMRI的优先级不低于PMI的优先级。
IMRI的优先级不低于LI的优先级。
IMRI的优先级不低于CQI的优先级。
IMRI的优先级高于IQI和/或Differential IQI的优先级。
IMRI的优先级高于RSRP和/或Differential RSRP的优先级。
RSRP的优先级不低于IQI和/或Differential IQI的优先级。
Differential IQI的优先级不高于Differential RSRP的优先级。
IQI和/或Differential IQI的优先级高于RI和/或LI的优先级;
IQI和/或Differential IQI的优先级高于PMI和/或CQI的优先级。
终端根据上述的优先级对CSI相关的参数进行编码,并有可能在编码率要求达不到***要求时,对优先级低的参数进行舍弃直到达到***编码率的要求。基站根据上述的优先级对CSI相关参数进行解码那么接收终端发送的信道状态 信息,包括如下情况至少之一:
当IMRI由CRI确定时,接收CRI;
当IMRI由SSBRI确定时,接收SSBRI;
接收至少一个CRI、RSRP和/或差分RSRP;
接收至少一个CRI、IQI和/或差分IQI;
接收至少一个CRI、RSRP和/或差分RSRP、IQI和/或差分IQI;
接收至少一个SSBRI、RSRP和/或差分RSRP;
接收至少一个SSBRI、IQI和/或差分IQI;
接收至少一个SSBRI、RSRP和/或差分RSRP、IQI和/或差分IQI;
接收至少一个IMRI、RSRP和/或差分RSRP;
接收至少一个IMRI、IQI和/或差分IQI;
接收至少一个IMRI、RSRP和/或差分RSRP、IQI和/或差分IQI;
接收至少一个CRI、至少一个IMRI、RSRP和/或差分RSRP;
接收至少一个CRI、至少一个IMRI、IQI和/或差分IQI;
接收至少一个CRI、至少一个IMRI、RSRP和/或差分RSRP、IQI和/或差分IQI。
在一实施例中,接收终端发送的信道状态信息,可以接收终端通过上行资源传输的信道状态信息,其中信道状态信息中的信道相关参数和干扰相关参数需要采用一定的编码方式进行编码处理,那么基站就可以采用与终端对应的解码方式实现解码。上行资源包括物理上行信道,高层信令。其中,物理上行信道至少包括以下之一:物理上行共享信道(Physical uplink shared channel,PUSCH)、物理上行控制信道(Physical uplink control channel,PUCCH),物理随机接入信道(Physical random-access channel,PRACH)。高层信令包括无线资源控制(Radio Resource Control,RRC)信令和媒体接入控制层控制单元(Media Access Control control element,MAC CE)信令。这里的上行资源都可以用于传输信道状态信息。
为了便于描述在一个报告中如何传输信道状态信息,需要先对的信道状态信息进行编码。在编码前需要确定信道状态信息各个变量的比特数目。首先,当前标准中已经定了CRI、SSBRI、RSRP等参数的比特数目,如表1所示。
表1
表2和表3示出IMRI、IQI、Differential IQI的比特数目。其中表2不包括IMRI,因为IMRI可能由CRI隐含传输。
表2
表3
或者所有的信道状态信息的位宽合并为一个表4。
表4
需要说明的是,如果IMRI由CRI或者SSBRI隐含指示,那么表4用表5的形式替换:
表5
在知道信道状态信息的传输比特后,以及它们的优先级后就可以对信道状态信息进行编码,并将编码后的信道状态信息在上行资源中传输给基站。
对信道状态信息进行编码的具体方法可以采用如下三种方式进行:
1)信道状态信息中的信道相关参数和干扰相关参数在一个编码块里联合编码。
此时,上行资源为PUCCH,信道状态信息中的信道相关参数和干扰相关参 数联合编码,具体的编码方式如表6所示。
表6
2)信道状态信息中的信道相关参数和干扰相关参数在两个编码块里独立编码。
此时,上行资源为PUCCH,信道状态信息中的信道相关参数和干扰相关参数独立编码,如图表7和表8所示,其中表7为信道相关参数的编码方式,表8为干扰相关参数的编码方式。
表7
表8
3)信道状态信息包括RSRP和IQI时,RSRP在第一部分编码块中编码,IQI在第二部分编码块的宽带或子带部分编码;信道状态信息包括差分RSRP和IQI时,差分RSRP在第一部分编码块中编码,IQI在第二部分编码块的宽带或子带部分编码;信道状态信息包括RSRP和差分IQI时,RSRP在第一部分编码块中编码,差分IQI在第二部分编码块的宽带或子带部分编码;信道状态信息包括差分RSRP和差分IQI时,差分RSRP在第一部分编码块中编码,差分IQI在第二部分编码块的宽带或子带部分编码;信道状态信息包括IQI但不包括RSRP和/或差分RSRP时,IQI在第一部分编码块中编码;信道状态信息包括差分IQI但不包括RSRP和/或差分RSRP时,差分IQI在第一部分编码块中编码;其中,第一部分编码块的传输优先级高于第二部分编码块的传输优先级。也就是终端 完成编码后,优先传输第一部分编码块中编码的信息。
其中,CRI、SSBRI、IMIR至少之一在第一部分编码块中编码,如表9所示,IQI、RSRP、Differential IQI、Differential RSRP至少之一在第二部分编码块中编码,如表10所示。
表9
表10
需要说明的是,如果IQI和RSRP只有一个存在时,可以只在第一部分编码块中编码。终端通过表6-表10的方式对信道状态信息进行编码,如果还存在其 他CSI参数也可以一起进行编码,将编码后的数据进行调制,资源映射等操作后在PUCCH上传输给基站,基站在PUCCH资源上接收信道状态信息,并通过解调、解码等一系列操作获得波束赋形相关的参数。
另外,如果在PUSCH上传输,那么除了表6-表10外还可能存在其他编码方式,例如表11-表13所示的编码形式。其中表11中,所有的信道状态信息在CSI报告的第一部分编码块里编码;表12中,以下参数至少之一在CSI报告的第一部分编码块里编码,CRI、SSBRI、IMRI、RSRP,Differential RSRP;表13表示以下参数至少之一在CSI报告的第二部分编码块的宽带部分进行编码:IQI和Differential IQI。
表11
表12
表13
即,对于PUSCH传输,包括如下特征之一:
信道相关参数和干扰相关参数都在CSI报告的第一部分编码块联合编码,或CRI、SSBRI、IMR以及RSRP、Differential RSRP至少之一在CSI报告的第一部分编码块编码,而IQI、Differential IQI至少之一在CSI报告的第一部分编码块宽带部分或CSI报告的第一部分编码块子带部分编码。
终端通过表6-表13的方式对信道状态信息进行编码,如果还存在其它CSI参数也可以一起进行编码,将编码后的数据进行调制,资源映射等操作后在PUSCH上传输给基站,基站在PUSCH资源上接收信道状态信息,并通过解调、解码等一系列操作获得波束赋形相关的参数。
需要说明的是,终端也可以通过表6-表13的方式对信道状态信息进行编码,并将一些信道状态信息在PUCCH上传输,而另外一部分信道状态信息在PUSCH上或者高层信令上传输。
需要说明的是,表6-表13只是对信道状态信息编码的一些实施例,也可以有其它的对信道状态信息进行任意组合和拆分的编码方式,这里不一一例举。
图4为一实施例提供的另一种信道测量方法的流程图,如图4所示,本实施例提供的方法包括如下步骤。
步骤S4010,接收测量资源信息,其中,测量资源信息包括N个信道测量 资源信息和M个干扰测量资源信息,N和M为正整数。
本实施例提供的信道测量方法应用于无线通信***中的终端设备,简称终端。终端根据基站分配的传输资源完成数据传输,并且接收基站发送的各种配置信息,根据各种配置信息确定传输所需资源,并执行各种配置信息所指示的测量指令。
在基站和终端通过多阵子阵列天线实现多波束赋型时,终端需要对基站赋型的多个波束进行测量,并向基站传输测量到的各波束的状态,从而使基站选择增益最大的波束作为最佳波束与终端建立信道进行数据传输。终端对各波束的RSRP进行测量并传输,也即将接收功率最大的波束作为终端所使用的的波束,但这样没有考虑到同频的其他波束的干扰,从而可能影响波束的选择。
为了解决上述问题,在本实施例中,终端接收基站发送的测量资源信息,其中,测量资源信息包括N个信道测量资源信息和M个干扰测量资源信息,N和M为正整数。
测量资源信息,以及测量资源信息中N个信道测量资源信息和M个干扰测量资源信息的具体含义和相互关系在图2所示实施例中已经详细说明,此处不再赘述。
步骤S4020,根据测量资源信息获取信道状态信息,信道状态信息包括信道相关参数和/或干扰相关参数。
终端接收到测量资源信息后,即可根据测量资源信息中包括的N个信道测量资源信息和M个干扰测量资源信息分别对信道和干扰进行测量,获取信道状态信息,信道状态信息包括信道相关参数和/或干扰相关参数。
信道状态信息的含义和信道相关参数和干扰相关参数的关系在图2所示实施例中已经详细说明,此处不再赘述。
步骤S4030,向基站传输信道状态信息。
终端在获取到信道状态信息后,向基站传输信道状态信息。基站接收到终端发送的测量到的各种参数,即信道状态信息,信道状态信息包括信道相关参数和/或干扰相关参数。其中信道相关参数是终端响应于信道测量资源而测量出的参数,干扰相关参数是终端响应于干扰测量资源而测量出的参数。当基站接收到终端发送的信道状态信息,即可确定基站发出的各波束对于终端的信道状态和干扰情况,从而基站可以选择出最优波束与终端建立通信连接实现数据传输。
对于图4所示实施例,信道测量资源和干扰测量资源的组成、相互关系,信道相关参数和干扰相关参数的组成,相互关系,基站如何向基站传输信道状 态信息,以及如何编码信道状态信息的具体方法已经在上述实施例中进行了详细说明,此处不再赘述。
需要说明的是,本申请实施例中,仅以基站配置测量资源信息,向终端测量资源信息后接收终端发送的信道状态信息为例进行了说明,也即通过上行资源传输信道状态信息。但实际上,由于终端也支持多波束赋形,对于基站和终端而言,同样可以通过下行资源传输信道状态信息,即基站向终端传输信道状态信息,使得终端选择适合的上行波束,具体的方法与本申请实施例提供的方法类似,区别仅在于将上行资源变为下行资源,本领域技术人员均能根据本申请所提供的信道测量方法,在下行资源上实现信道状态信息的传输,本实施例中不再赘述。
另外,对于同一个接收端,在相同的符号上使用相同的接收波束进行接收信号,这在多个发射接收点(Transmission and Reception Point,TRP)联合传输的时候并不能很好地根据不同TRP对应的信道特征来灵活地接收信道或者信号。为此本申请实施例还提供一种空间接收参数的确定方法。
本申请实施例中的一种空间接收参数的确定方法包括:确定A类信道和/或信号关联的组信息;
根据确定的A类信道和/或信号关联的组信息,确定如下至少之一:A类信道和/或信号中的至少一类信道和/或信号的空间接收参数,A类信道和/或信号的传输方式;
其中A类信道和/或信号占有的时域资源之间的交集非空,A为大于或等于2的正整数。
在本申请实施例中,确定A类信道和/或信号关联组信息;根据A类信道和/或信号关联的组信息,确定A类信道和/或信号中的至少一类信道和/或信号的空间接收参数。
根据确定的A类信道和/或信号关联的组信息,确定A类信道和/或信号中的至少一类信道和/或信号的空间接收参数,包括如下至少之一:
A类信道和/或信号关联的组信息相同时,A类信道和/或信号关于空间接收参数满足准共址关系;
A类信道和/或信号关联的组信息相同时,A类信道和/或信号在交集部分关于空间接收参数满足准共址关系;

A类信道和/或信号关联的组信息不同时,A类信道和/或信号在交集部分分别关联一个空间接收参数。
下面以A=2为例进行说明,下述的描述中A类信道和/或信号关联的组信息相同时满足如下关系,如果A类信道和/或关联的组信息不同时,不需要满足如下关系。
情况1:当调度PDSCH的下行控制信息(Downlink Control Information,DCI)和物理下行共享信道(Physical Downlink shared channel,PUSCH)之间的间距小于预定阀值,PDSCH和控制资源集合(Control resource set,CORESET)之间时域交集非空(CORESET是配置为用于传输下行控制信息的时频资源块),PDSCH和CORESET的'QCL-TypeD'(即空间接收参数)不同,PDSCH和CORESET关联相同的组信息时,优先接收CORESET中的物理下行控制信道(Physical Downlink control channel,PUCCH)。此时PDSCH的'QCL-TypeD'是距离PDSCH最近的时间单元中关联至少一个要检测的搜索空间具有最低CORESETID且在PDSCH所在的载波组件(Carrier Component,CC)中的CORESET的'QCL-TypeD'。

情况3:如果终端配置的CSI-RS资源和SS/PBCH资源块占有的OFDM时域符号交集非空,并且CSI-RS资源和SS/PBCH资源块有相同的组ID,如果'QCL-TypeD'有被应用,那么CSI-RS和SS/PBCH资源块是关于'QCL-TypeD'满足准共址关系。
情况4:如果终端接收的PDSCH的DMRS和SS/PBCH资源块占有的OFDM符号交集非空,PDSCH的DMRS和SS/PBCH资源块有相同的组ID,且如果'QCL-TypeD'被配置了,那么DM-RS和SS/PBCH资源块是关于'QCL-TypeD'满足准共址关系。

在一实施例中,在上述情况1~5中,当A类信道和/或信号关联的组信息不同时,他们之间不需要关于空间接收参数满足准共址关系。
