在终端具有多个天线阵面时,网络侧设备在进行波束管理时,会向终端发送多个不同方向的波束用于终端的波束测量。网络侧设备通过为终端配置的不同CSI参考信号资源集向终端发送CSI参考信号,由于终端具备多个天线阵面,在接收网络侧设备发送的CSI参考信号时,终端只能从多个天线阵面中随机选择一个天线阵面用于接收并测量CSI参考信号,并将测量得到的测量结果进行上报。此后,网络侧设备后续的波束指示均是基于该CSI测量过程上报的测量结果进行的,如果终端在CSI测量过程中接收CSI参考信号使用的天线阵面传输质量较差,在终端上报测量结果之后,在后续网络侧设 备向终端发送下行数据时,若终端继续使用该较差的天线阵面进行接收,将会导致下行数据传输失败。
基于上述问题,如图1所示,本申请实施例提供一种CSI测量上报的系统,包括终端10和网络侧设备20;
终端10,用于根据预设的规则或网络侧设备的配置信息,确定天线端口参数;根据确定出的所述天线端口参数,接收并测量所述网络侧设备配置的至少一个资源单元中的CSI参考信号;根据对所述至少一个资源单元中的CSI参考信号进行测量的测量结果,生成上报参量并上报给所述网络侧设备。
网络侧设备20,用于向终端发送配置信息,以使所述终端根据所述配置信息确定接收并测量所述网络侧设备配置的至少一个资源单元中的CSI参考信号需要使用的天线端口参数;通过配置的至少一个资源单元向所述终端发送CSI参考信号,以使所述终端对所述CSI参考信号进行CSI测量并根据测量结果生成上报参量;接收所述终端上报的上报参量。
由于本申请实施例在CSI测量过程中,终端可以根据预设的规则或网络侧设备的配置信息确定用于接收CSI参考信号的天线端口参数,网络侧设备通过至少一个资源单元向终端发送CSI参考信号后,终端根据确定出的天线端口参数,接收并测量网络侧设备配置的至少一个资源单元中的CSI参考信号;这样,可以令终端使用所有的天线端口集合或天线阵面接收并测量CSI参考信号,进而对使用所有的天线端口集合或天线阵面获得的测量结果进行上报,使得网络设备侧获得相对较优的天线端口集合或天线阵面。在后续网络侧设备与终端通信过程中,网络设备侧可以配置终端使用较优的天线端口集合或天线阵面来进行下行数据的接收,进一步提高系统性能。
其中,本申请实施例的资源单元可以为CSI资源集(CSI Resource Setting)、CSI资源集中的CSI资源子集(CSI Resource set)、CSI资源中的至少一种;
需要说明的是,一个CSI资源集中可以包括多个CSI资源子集,一个CSI资源子集中又可以包括多个CSI资源。一个CSI资源子集可以是非零功率的CSI资源子集(NZP-CSI-RS-ResourceSet),零功率的CSI资源子集 (CSI-IM-ResourceSet),或者是由SSB资源组成的CSI资源子集(CSI-SSB-ResourceSet)。相应地,一个CSI资源可以是非零功率的CSI资源(NZP CSI-RS资源),零功率的CSI资源(CSI-IM资源),或者SSB资源。
本申请实施例的至少一个资源单元可以是至少一个CSI资源集,或者至少一个资源单元可以是同一个CSI资源集中的至少一个CSI资源子集,或者至少一个资源单元可以是同一个CSI资源集中的至少一个CSI资源,或者至少一个资源单元可以是同一个CSI资源子集中的至少一个CSI资源。
网络侧设备向终端发送CSI参考信号时,是通过配置的资源单元中的CSI资源承载CSI参考信号;
假设资源单元为CSI资源子集,若一个CSI资源子集中包括有多个CSI资源,则该资源单元中的CSI参考信号也有多个。
在网络侧设备为终端配置至少两个用于发送CSI参考信号的资源单元时,至少两个资源单元为具有相同或不同时域传输特性的资源单元;或至少两个资源单元为同一个周期性CSI资源集对应的至少两个CSI资源子集;或至少两个资源单元为同一个半持续CSI资源集对应的至少两个CSI资源子集;或至少两个资源单元为与一个非周期触发状态关联的或一个非周期CSI资源集对应的至少两个非周期CSI资源子集;或至少两个资源单元为同一个CSI资源集或CSI资源子集中包含的CSI资源。
本申请实施例终端在确定接收CSI参考信号的天线端口参数时,可以根据预先设定的规则进行确定,或者终端还可以根据网络侧设备发送的配置信息确定。下面针对不同的确定天线端口参数的方式分别进行说明。
方式一、终端根据预设的规则确定天线端口参数。
在该种方式下,终端预先存储预设的规则,在需要接收网络侧设备配置的至少一个资源单元中的参考信号时,终端根据预设的规则确定接收至少一个资源单元中的参考信号需要使用的天线端口参数。
一种可选的实施方式为,本申请实施例预设的规则包括下列规则中的至少一种:
规则1、根据资源单元或资源单元中的CSI参考信号的数量,确定不同资源单元或者资源单元中的CSI参考信号对应的天线端口参数相同或不同;
规则2、根据索引相同的至少两个资源单元或资源单元中的CSI参考信号,确定天线端口参数不同;
规则3、根据索引不同的至少两个资源单元或资源单元中的CSI参考信号,确定天线端口参数相同或不同;
规则4、根据空间QCL关系相同的至少两个资源单元或资源单元中的CSI参考信号,确定天线端口参数不同;
规则5、根据空间QCL关系不同的至少两个资源单元或资源单元中的CSI参考信号,确定天线端口参数相同或不同。
需要说明的是,在终端确定用于接收网络侧设备配置的至少一个资源单元中的CSI参考信号之前,网络侧设备向终端发送资源配置信息,终端根据网络侧设备发送的资源配置信息,可以确定网络侧设备为终端配置的资源单元的个数以及具体的资源单元。终端根据网络侧设备发送的资源配置信息,根据上述规则中的至少一个规则确定天线端口参数。
在网络侧设备为终端配置一个资源单元时,由于该资源单元中可以包括多个更小粒度的资源单元,在确定接收网络侧设备配置的一个资源单元中的CSI参考信号时,可以基于该资源单元中包括的更小粒度的资源单元,根据上述规则1~5中的至少一个规则确定需要使用的天线端口参数;
例如,网络侧设备为终端配置一个CSI资源子集,该CSI资源子集中包含多个CSI资源,则终端可以基于CSI资源子集中包含的多个CSI资源,依据上述规则1~5中的至少一个规则确定需要使用的天线端口参数。
若终端根据网络侧设备发送的资源配置信息,确定为终端配置至少两个资源单元时,终端可以根据上述规则1~规则5中至少一个规则确定天线端口参数;
针对上述规则1,终端根据资源单元或资源单元中的CSI参考信号的数量,确定至少两个资源单元对应的天线端口参数相同或不同;
当为终端配置特定数量的资源单元时,则终端确定使用相同或不同的接收天线端口参数来接收资源单元中的CSI参考信号;其中特定数量可以是在协议中预先规定的。例如,当资源单元个数为2时,如一个CSI资源集包含至少2个CSI资源子集,或者一个CSI资源子集包含至少2个CSI资源时,则终端确定使用不同的接收天线端口参数来接收资源单元中的CSI参考信号。又例如,当CSI资源单元个数为N时,终端确定使用相同或不同的天线端口参数来接收资源单元中的CSI参考信号。
另外,终端还可以根据上述规则1,根据确定资源单元或资源单元中的CSI参考信号的数量,确定资源单元中的CSI参考信号是网络侧设备使用相同或不同的天线端口参数发送的。例如,当资源单元个数为2时,如一个CSI资源集包含至少2个CSI资源子集,或者一个CSI资源子集包含至少2个CSI资源时,则终端确定资源单元中的CSI参考信号是网络侧设备使用不同的天线端口参数发送的;又例如,当CSI资源单元个数为N时,终端确定资源单元中的CSI参考信号是网络侧设备使用相同的天线端口参数发送的。
实施中,终端根据网络侧设备发送的资源配置信息,确定为终端配置的至少两个资源单元的索引;
针对上述规则2,终端根据索引相同的至少两个资源单元或资源单元中的CSI参考信号,确定至少两个资源单元对应的天线端口参数不同;
如果至少两个资源单元的索引相同,则表示网络侧设备通过两个相同的资源单元发送CSI参考信号,据此配置,终端可以确定使用不同的天线参数来接收至少两个资源单元中的CSI参考信号;例如,终端使用不同的接收天线阵面或不同的接收天线端口集合或不同的接收空间滤波器来对至少两个资源单元中的CSI参考信号进行接收,并基于此天线端口参数对至少两个资源单元中的CSI参考信号进行测量和上报。这样,网络侧设备就可以获知终端使用不同的天线端口参数对相同资源单元的测量结果,进而可以确定哪种用于接收CSI参考信号的天线端口参数性能更优。
针对上述规则3,终端根据索引不同的至少两个资源单元或资源单元中的 CSI参考信号,确定至少两个资源单元对应的天线端口参数相同或不同;
如果至少两个资源单元的索引不同,则终端可以使用相同或不同的天线端口参数来接收至少两个CSI资源单元中的CSI参考信号,这样,终端就可以根据测量结果确定哪个资源单元对应的发送信号更优。
实施中,终端根据网络侧设备发送的资源配置信息,确定为终端配置的至少两个资源单元的空间QCL关系;
针对上述规则4,终端根据空间QCL关系相同的至少两个资源单元或资源单元中的CSI参考信号,确定至少两个资源单元对应的天线端口参数不同;
当网络侧设备为终端配置的至少两个资源单元的空间QCL关系相同,则终端确定使用不同的接收天线端口参数来接收资源单元中的CSI参考信号。
另外,在网络侧设备为终端配置的至少两个资源单元的空间QCL关系相同时,终端还可以确定资源单元中的CSI参考信号是网络侧设备使用不同的天线端口参数发送的。
针对上述规则5,终端根据空间QCL关系不同的至少两个资源单元或资源单元中的CSI参考信号,确定至少两个资源单元对应的天线端口参数相同或不同;
当网络侧设备为终端配置的至少两个资源单元的空间QCL关系不同,则终端确定使用相同或不同的接收天线端口参数来接收资源单元中的CSI参考信号。
在网络侧设备为终端配置的至少两个资源单元的空间QCL关系不同时,终端还可以确定资源单元中的CSI参考信号是网络侧设备使用相同或不同的天线端口参数发送的。
另外,还可以预先定义每个资源单元对应的天线端口参数,在网络侧设备向终端发送资源配置信息之后,终端根据资源配置信息中包含的网络侧设备为终端配置的资源单元,根据资源单元与天线端口参数之间的对应关系,确定每个资源单元对应的天线端口参数。
另外,本申请实施例在根据预设的规则确定天线端口参数时,可以根据 预设的规则,从终端对应的备选天线端口参数中确定所述天线端口参数;
例如,假设为终端配置的备选天线端口参数为两个天线阵面时,终端可以根据预设的规则,从两个天线阵面中确定接收并测量至少一个资源单元中的CSI参考信号使用的天线阵面。
方式二、终端根据网络侧设备的配置信息确定天线端口参数。
实施中,网络侧设备向终端发送配置信息,终端根据网络侧设备发送的配置信息确定接收至少一个资源单元中的CSI参考信号使用的天线端口参数;

其中,高层信令参数包括以下至少一种:CSI上报集中的配置或其下面的参数配置、基于组的波束上报配置或其下面的参数配置、CSI资源单元中的配置或其下面的参数配置。
1、高层信令参数为CSI上报集中的配置或其下面的参数配置;
网络设备侧可以在CSI上报集(CSI-ReportConfig)中直接配置终端接收网络侧设备配置的至少一个资源单元中的CSI参考信号使用的天线端口参数。例如,在CSI上报集中配置终端使用哪一个或哪一组天线阵面或接收天线端口集合或接收滤波器来进行资源单元中CSI参考信号的测量和上报。例如,网络设备侧发送2个CSI上报集配置,2个CSI上报集配置和相同的CSI资源单元相关联,且2个CSI上报集配置中配置终端使用不同的天线端口参数来进行测量上报,这样网络设备侧就可以根据终端上报的测量结果确定哪个接收天线面阵的性能更优。
另外。还可以将接收天线端口参数配置于CSI上报集配置下面的IE中,例如IE groupBasedBeamReporting。
2、高层信令参数为基于组的波束上报配置或其下面的参数配置;
在R16协议中,基于组或不基于组的波束上报配置在IE groupBasedBeamReporting下面,如下所示:
本申请实施例可以将天线端口参数加入到groupBasedBeamReporting中,或者groupBasedBeamReporting下面的IE enabled配置中,或者disabled配置中或者nrofReportedRS配置中等。天线端口参数的IE,例如,可以称为antenna_info,也可以用其它的参数名称来代替。
例如,
又例如,
又或者
3、高层信令参数为CSI资源单元中的配置或其下面的参数配置;

关于antenna_info的具体内容,可以是,
antenna_info CHOICE{
相同接收天线端口参数,
不同接收天线端口参数,
}
又例如,
antenna_info CHOICE{
相同接收天线端口参数,CHOICE{
接收天线端口参数i
}
不同接收天线端口参数,CHOICE{

}
方式2、网络侧设备通过媒体接入层控制单元(MAC Control Element,MAC-CE)信令向所述终端发送配置信息;
方式3、网络侧设备通过下行控制信息(Downlink Control Information,DCI)向所述终端发送配置信息。
一种可选的实施方式为,网络侧设备向终端发送的配置信息包括:
用于指示终端使用相同或不同的天线端口参数接收并测量至少一个资源单元中的CSI参考信号的指示信息;或
天线端口参数;其中,所述天线端口参数为终端接收并测量所述至少一个资源单元中的CSI参考信号使用的天线端口参数。
例如,网络侧设备通过向终端发送配置信息,指示终端使用相同的天线端口参数接收并测量至少一个资源单元中的CSI参考信号;或
网络侧设备通过向终端发送配置信息,指示终端使用不同的天线端口参数接收并测量至少一个资源单元中的CSI参考信号;或
网络侧设备通过向终端发送配置信息,指示终端接收并测量至少一个资源单元中的CSI参考信号使用的天线端口参数;例如,网络侧设备指示终端使用天线阵面i和/或天线阵面j接收并测量至少一个资源单元中的CSI参考信号;或者网络侧设备指示终端使用天线端口组m和/或天线端口组n接收并测量至少一个资源单元中的CSI参考信号。
另外,网络侧设备还可以通知终端网络侧设备发送至少一个资源单元的CSI参考信号使用的天线端口参数;
例如,网络侧设备通知终端,网络侧设备使用相同的天线端口集合或传输配置指示(Transmission Configuration Indicator,TCI)来发送至少一个CSI资源单元中的CSI参考信号;或者,网络设备侧使用不同的天线端口集合或TCI来发送至少一个CSI资源单元中的CSI参考信号。
本申请实施例终端根据预设的规则或网络设备侧的配置信息,确定天线端口参数与至少一个资源单元的关联关系;
其中,在网络侧设备配置一个资源单元时,关联关系包括一个资源单元与天线端口参数相关联;
在网络侧设备配置至少两个资源单元时,关联关系包括下列关系中的至少一种:
至少两个资源单元与相同的天线端口参数相关联;
至少两个资源单元与不同的天线端口参数相关联;
至少两个资源单元分别对应一种天线端口参数。
例如,相关联指的是至少两个资源单元是由关联的天线端口参数去接收,或者,至少两个资源单元是由网络设备侧关联的天线端口参数来发送的。例如,网络侧设备配置两个资源单元,每个资源单元与一种天线端口参数相关联,例如第一个资源单元与一个接收天线阵面或接收天线端口组合关联,第二个资源单元与另一个接收天线阵面关联,待终端确定关联的天线端口参数以后,就可以使用天线端口参数指示的天线阵面来接收相应的资源单元。又例如,一个CSI资源子集包含至少两个CSI资源,每个CSI资源与一种天线端口参数相关联,或者前N/2个CSI资源和一种天线端口参数相关联,后N/2个CSI资源和另一种天线端口参数相关联。当终端确定关联的天线端口参数以后,就可以使用天线端口参数指示的天线阵面、天线端口集合或空间滤波器来接收相应的CSI资源。
本申请实施例终端在确定接收网络侧设备配置的至少一个资源单元中的CSI参考信号使用的天线端口参数之后,终端通过确定出的天线端口参数,接收并测量网络侧设备配置的至少一个资源单元中的CSI参考信号,并向网络侧设备发送上报参量;
一种可选的实施方式为,终端在通过确定出的天线端口参数,接收并测量网络侧设备配置的至少一个资源单元中的CSI参考信号时,终端在相同或不同的时域资源上接收网络侧设备配置的至少一个资源单元中的CSI参考信号;
其中,时域资源可以为一个时隙,或一个正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)符号、或大于一个时隙、或大于一个OFDM符号。
终端向网络侧设备发送的上报参量中至少包括得到所述测量结果所使用的天线端口参数;
例如,终端对网络侧设备配置的资源单元A中的CSI参考信号进行测量,并上报对资源单元A中的CSI参考信号测量得到的上报参量,则该上报参量 中包含接收资源单元A中的CSI参考信号使用的天线端口参数。另外,该上报参量中还可以包含网络侧设备发送资源单元A中的CSI参考信号使用的天线端口参数。
当配置至少两个资源单元时,每个资源单元中的CSI参考信号可以使用不同的天线端口参数进行接收,以及可以使用不同的天线端口参数进行发送,因此可以具有不同的测量结果。当至少两个资源单元和1个CSI上报集相关联时,会针对至少两个CSI资源单元上报测量结果。为了将不同的测量结果同时反馈给网络,可以规定终端按照如下方式进行CSI上报。
实施中,终端可以根据下列方式确定用于向网络侧设备发送的上报参量:
方式1、终端针对每个资源单元上报一个上报参量;
当终端接收每个资源单元中的CSI参考信号使用不同的接收天线端口参数,和/或网络侧设备使用不同的发送天线端口参数发送每个资源单元中的CSI参考信号时,或者,每个CSI资源单元的配置都不同时;终端确定针对每一个资源单元分别上报一个上报参量;
所述不同的接收或发送天线端口参数包括,网络设备侧直接指示终端使用不同的接收或发送天线端口参数来发送或接收资源单元,或者终端根据网络设备侧指示的接收或发送天线端口参数判断出2个资源单元的接收或发送天线端口参数是不同的(例如,一个是接收或发送天线端口参数为i,一个是接收或发送天线端口参数为j)。
方式2、终端根据所有资源单元上报一个上报参量;
例如,网络侧设备为终端配置多个资源单元,则终端对多个资源单元中的CSI参考信号进行测量,并针对该多个资源单元上报一个上报参量;
需要说明的是,终端针对一个资源单元中的CSI参考信号可以得到一个测量结果,则终端根据所有的资源单元对应的测量结果确定一个上报参量;具体的,可以将所有资源单元对应的测量结果进行计算确定一个上报参量,例如,利用多个测量的资源单元的接收功率值计算信道和干扰噪声功率比值作为上报参量,或者,可以将所有资源单元对应的测量结果中质量最优的测 量结果作为上报参量,例如,将所有资源单元的测量到的层1参考信号接收功率(Layer 1 Reference Signal Received Power,L1-RSRP)值进行比较,选出质量最优的L1-RSRP值作为上报参量。
方式3、终端针对每N/M个资源单元上报一个上报参量,N为资源单元的个数,M为网络配置或预定义的测量参数的个数;
当网络侧配置终端上报M个测量参数时(例如,基于非组的上报时M=1,2,3,4中的一个,或基于组的上报时M=2),终端侧会根据网络侧设备配置的N个资源单元上报M个上报参量。可以预先规定,终端根据每N/M个资源单元上报一个上报参量;
终端在根据每N/M个资源单元上报一个上报参量时,终端根据对N/M个资源单元中的CSI参考信号进行测量得到的测量结果确定一个上报参量,共确定M个上报参量进行上报。
其中,可以预定义测量参数的个数M的取值为2(例如基于组的上报),终端侧会根据网络侧设备配置的N个资源单元上报2个上报参量。可以预先规定,终端根据前N/2个资源单元上报一个上报参量,根据后N/2个资源单元上报一个上报参量。其中,N为偶数或N不为奇数。
本申请实施例终端向网络侧发送的上报参量可以是cri-RSRP,ssb-Index-RSRP,cri-SINR-r16,ssb-Index-SINR-r16,cri-RI-CQI,cri-RI-PMI-CQI,cri-RI-i1,cri-RI-i1-CQI,cri-RI-LI-PMI-CQI。除此之外,还可以包含CSI资源单元所使用的接收或发送天线端口参数,用于指示某个上报参量是基于哪种接收或发送天线端口参数进行测量的。这样,终端也可以在预设或网络侧设备侧配置的多种接收或发送天线端口参数中选出K个测量较优的进行反馈。
接收或发送天线端口参数可以使用如下方法上报,使用P比特分别代表至多2^P种接收或发送天线端口参数,例如P可以等于1,比特‘0’和‘1’分别表示使用相同接收或发送天线端口参数和使用不同接收或发送天线端口参数;N还可以大于等于2,每一个码点(codepoint)分别表示一个接收或发送天线端口参数,或者2个或以上接收或发送天线端口参数的组合。
当配置终端上报K个L1-RSRP值时,终端的上报内容可以是:
接收或发送天线端口参数或参数组合1,L1-RSRP value 1,接收或发送天线端口参数或参数组合2,L1-RSRP value 2,…..,接收或发送天线端口参数或参数组合K,L1-RSRP value K。
还可以将以上上报内容扩展到其它CSI上报中,例如层1-信号与干扰加噪声比(layer1-signal to interference plus noise ratio,L1-SINR),或者CSI参考信号资源指示(CSI-RS Resource Indicator,CRI),信道质量指示(Channel Quality Indication,CQI),预编码矩阵指示(Precoding Matrix Indicator,PMI),秩指示(Rank Indicator,RI)等的组合上报中,只需将L1-RSRP值替换成相应的CSI上报值即可。
终端将确定的上报参量上报给网络侧设备之后,网络侧设备可以根据终端发送的上报参量,从终端对应的多个天线端口参数中确定出终端用于接收下行数据的天线端口参数;
另外,网络侧设备还可以从多个天线端口参数中确定出用于向终端发送下行数据的天线端口参数。
