技术领域
本申请涉及通信技术领域,尤其涉及一种测量上报方法及装置。
背景技术
目前,当网络侧设备部署了多个TRP(TRansmission Point,传输点),且终端具有多个接收天线阵面(panel)时,终端可以同时接收多个TRP的信号,即可以同时接收具有多个不同QCL-TypeD(Quasi-Co-Location type D,准共址类型D)参数的信号。
然而,在现有技术中,基于组的波束上报和不基于组的波束上报中,终端均不清楚CSI(Channel State Indication,信道状态信息)测量集中的CSI-RS(Channel State Indication Reference Signal,信道状态指示参考信号)来自哪个TRP,因此上报的2个或至多4个波束可能由相同的TRP发送,或不同的TRP发送。例如,在TRP传输场景下,终端按照L1-RSRP(Layer-1Reference Signal Receiveing Power,层1参考信号接收功率)最大值上报的波束可能是来自同一个TRP,即适合单TRP传输时的测量结果,也即不能为多TRP传输提供有效的测量结果。
可见,现有技术中没有针对多个TRP多panel场景下的测量上报进行考虑,即亟需一种多TRP场景下的波束测量上报方法。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚明白,下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。在不冲突的情况下,本申请中的实施例及实施例中的特征可以相互任意组合。并且,虽然在流程图中示出了逻辑顺序,但是在某些情况下,可以以不同于此处的顺序执行所示出或描述的步骤。
为了更好的理解本方案,下面对涉及的一些过程以及名词进行说明:
1、终端设备:
本申请实施例涉及的终端设备,可以是指向用户提供语音和/或数据连通性的设备,具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备等。在不同的系统中,终端设备的名称可能也不相同,例如在5G系统中,终端设备可以称为用户设备(User Equipment,UE)。无线终端设备可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网(Core Network,CN)进行通信,无线终端设备可以是移动终端设备,如移动电话(或称为“蜂窝”电话)和具有移动终端设备的计算机,例如,可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置,它们与无线接入网交换语言和/或数据。例如,个人通信业务(Personal Communication Service,PCS)电话、无绳电话、会话发起协议(Session Initiated Protocol,SIP)话机、无线本地环路(Wireless Local Loop,WLL)站、个人数字助理(Personal Digital Assistant,PDA)等设备。无线终端设备也可以称为系统、订户单元(subscriber unit)、订户站(subscriber station),移动站(mobile station)、移动台(mobile)、 远程站(remote station)、接入点(access point)、远程终端设备(remote terminal)、接入终端设备(access terminal)、用户终端设备(user terminal)、用户代理(user agent)、用户装置(user device),本申请实施例中并不限定。
2、网络侧设备:
本申请实施例涉及的网络侧设备,可以是基站,该基站可以包括多个为终端提供服务的小区。根据具体应用场合不同,基站又可以称为接入点,或者可以是接入网中在空中接口上通过一个或多个扇区与无线终端设备通信的设备,或者其它名称。网络侧设备可用于将收到的空中帧与网际协议(Internet Protocol,IP)分组进行相互更换,作为无线终端设备与接入网的其余部分之间的路由器,其中接入网的其余部分可包括网际协议(IP)通信网络。网络侧设备还可协调对空中接口的属性管理。例如,本申请实施例涉及的网络侧设备可以是全球移动通信系统(Global System for Mobile communications,GSM)或码分多址接入(Code Division Multiple Access,CDMA)中的网络侧设备(Base Transceiver Station,BTS),也可以是带宽码分多址接入(Wide-band Code Division Multiple Access,WCDMA)中的网络侧设备(NodeB),还可以是长期演进(long term evolution,LTE)系统中的演进型网络侧设备(evolutional Node B,eNB或e-NodeB)、5G网络架构(next generation system)中的5G基站(gNB),也可以是家庭演进基站(Home evolved Node B,HeNB)、中继节点(relay node)、家庭基站(femto)、微微基站(pico)等,本申请实施例中并不限定。在一些网络结构中,网络侧设备可以包括集中单元(centralized unit,CU)节点和分布单元(distributed unit,DU)节点,集中单元和分布单元也可以地理上分开布置。
具体的,网络侧设备与终端设备之间可以各自使用一或多根天线进行多输入多输出(Multi Input Multi Output,MIMO)传输,MIMO传输可以是单用户MIMO(Single User MIMO,SU-MIMO)或多用户MIMO(Multiple User MIMO,MU-MIMO)。根据根天线组合的形态和数量,MIMO传输可以是2D-MIMO、3D-MIMO、FD-MIMO或massive-MIMO,也可以是分集传输或 预编码传输或波束赋形传输等。
3、CSI上报的过程:
在现有协议中,网络侧设备可以为终端配置CSI资源集合(CSI Resource Setting,信道状态信息资源集),其对应高层参数可表示为CSI-ResourceConfig;以及CSI上报集合(Reporting Setting),其对应高层参数可表示为CSI-ReportConfig,以用于CSI的测量和上报。其中,每个CSI上报集合和至多3个CSI资源集合相关联,并且配置一个上报量(report Quantity)用于指示终端上报的内容。具体的,上报量包含以下部分或全部:L1-RSRP(Layer-1Reference Signal Receiveing Power,层1参考信号接收功率),其对应高层参数‘cri-RSRP’或‘ssb-Index-RSRP’;以及,L1-SINR(Layer-1Signal to Interference plus Noise Ratio,层1信号与干扰加噪声比),其对应高层参数‘cri-SINR’或‘ssb-Index-SINR’);以及,CQI(Channel Quality Indication,信道质量指示),PMI(Precoding Matrix Indicator,预编码矩阵指示),RI(Rank Indication,秩指示),CRI(CSI reference signal Resource Indication,CSI-RS资源指示),SSBRI(Synchronization Signal Block Resource Indicator,同步信号块资源指示)等。
终端设备可以针对CSI上报集合所关联的CSI资源集合进行测量,并按照CSI上报集合中配置的上报量进行上报。
4、波束上报:
L1-RSRP和L1-SINR均为波束管理过程中针对波束质量的上报参数,其上报过程采用如上所述的CSI上报的过程。
进一步地,网络侧设备还可以配置终端进行基于组的波束上报(group based beam reporting),和不基于组的波束上报(non-group based beam reporting)。即在CSI上报集合配置(CSI-ReportConfig)中包含参数groupBasedBeamReporting,具体的,上报的波束个数是可以配置的,即参数nrofReportedRS,上报的波束个数至多4个。
然而,如前所述,现有技术中,并没有针对多个TRP多panel场景下的 测量上报进行考虑。例如,在现有的基于组的波束上报和不基于组的波束上报中,终端均不清楚CSI测量集中的CSI-RS来自哪个TRP,因此上报的2个或至多4个波束可能由相同的TRP发送,或不同的TRP发送。例如,在TRP传输场景下,终端按照L1-RSRP最大值上报的波束可能总是来自同一个TRP,也即适合单TRP传输时的侧结果,因此不能为多TRP传输提供有效的测量结果。
鉴于此,本申请提供一种测量上报方法,通过该方法可以实现在多TRP场景下的波束测量上报方法,使得终端可以上报有利于多TRP同时传输所需要的测量结果。
请参见图1,图1为本申请实施例中的一种测量上报方法的流程示意图。
步骤101:根据网络侧设备的配置,确定每个CSI-RS组用于测量时的QCL-TypeD参数以及用于测量时的测量集合。
在本申请实施例中,网络侧设备可以为终端配置一个CSI资源集合,也可以为终端配置两个CSI资源集合,从而终端可以基于网络侧设备的配置,确定每个信道状态指示参考信号CSI-RS组用于测量时的QCL-TypeD参数以及用于测量时的测量集合。
需要说明的是,在本申请的所有实施例中,CSI资源集合(即CSI resource setting)可以配置多个CSI-RS资源集(即CSI resource set),每个CSI-RS资源集为一个CSI-RS资源组。或者,一个CSI资源集合可以配置一个CSI-RS资源集,一个CSI-RS资源集配置多个CSI-RS资源子集,每个CSI-RS资源子集为一个CSI-RS资源组;或者,一个CSI资源集合可以配置一个CSI-RS资源集,一个CSI-RS资源集中包含多个CSI-RS资源,通过高层信令参数或组索引或物理小区ID隐式地将多个CSI-RS资源分成多个CSI-RS资源组。
并且,后文中为了便于描述,均以CSI-RS资源组为例进行说明。在实际实施过程中,可以基于前述的CSI资源集或者CSI资源集合表述本方案提供的测量上报方法,本申请对此不作限制。此外,需要说明的是,在本申请实施例中,CSI-RS组可以理解为CSI-RS资源组。
本申请所有实施例中的CSI-RS资源也可以用SSB资源代替,即CSI resource setting或CSI resource set包含其中资源为SSB(Synchronization Signal Block,同步信号块)的情况。

(3)基于与CSI-RS资源关联的高层参数配置取值由小到大的顺序确定的第m个CSI-RS组。
(4)基于每个CSI-RS组中具有最小索引的CSI-RS资源的索引由小到大的顺序确定的第m个CSI-RS组。
可见,在本申请实施例中,可以采用多种方式确定第m个CSI-RS组,提供了多种实施方案,增强了本申请所提供的方案的可实施性。
步骤102:基于QCL-TypeD参数对测量集合进行测量,确定N组测量上报值;N为不小于1的正整数。
在本申请实施例中,可以根据确定的QCL-TypeD参数接收CSI-RS资源,确定L1-RSRP或L1-SINR测量值,然后根据L1-RSRP或L1-SINR,确定N组测量上报值中包含的CSI-RS资源指示CRI或同步信号块资源指示SSBRI。
在本申请实施例中,根据CSI-RS资源所对应的K个CSI-RS组的L1-RSRP或L1-SINR测量值进行从高到低的排序,确定N组中任一组测量上报值包含的CRI或SSBRI。
例如,上报的第1组CRI/SSBRI对应每个CSI-RS组中具有最大L1-RSRP或L1-SINR值的CSI-RS资源;上报的第2组CRI/SSBRI为每个CSI-RS组中具有次大L1-RSRP或L1-SINR值的CSI-RS资源,依次类推,从而确定上报的N组测量值。
在具体的实施过程中,终端上报的第z组CRI/SSBRI为每个CSI-RS组中具有最z大L1-RSRP值的CSI-RS资源。其中,z的取值为0-N任一值,终端从K个CSI-RS资源隐式组或CSI资源集中分别选出L1-RSRP值最大的波束,即(CSI-RS资源)作为第1组测量上报值。然后从K个CSI-RS资源隐式组或CSI资源集中分别选出L1-RSRP值次大的波束即CSI-RS资源作为第2组测量结果;以此类推,直到从K个CSI-RS资源隐式组或CSI资源集中分别选出L1-RSRP值第N大的波束(CSI-RS资源)作为第N组测量结果。每组测量结果的第m(k=1,2,…,K)个测量值来自第m(k=1,2,…,K)个CSI-RS资源隐式组或CSI资源集。如果一个CSI-RS资源和多个CSI-RS资源隐式组或CSI资源集关联,例如和第k1个和第k2个CSI-RS资源隐式组或CSI资源集关联,则该CSI-RS资源对应的测量结果在上报时可以出现在每组测量结果的第k1和第k2个位置上。本方法中的上报方法也可以叫组间上报。
在本申请实施例中,还可以对CSI-RS资源所对应的单个CSI-RS组所包括L1-RSRP或L1-SINR上报值进行排序,基于每个CSI-RS组的组内最大L1-RSRP或L1-SINR值,确定N组中任一组测量上报值包含的CRI或SSBRI。
例如,上报的第1组CRI/SSBRI为某个CSI-RS组中具有最大L1-RSRP或L1-SINR值的CSI-RS资源;上报的第2组CRI/SSBRI为某个CSI-RS组中 具有次大L1-RSRP或L1-SINR值的CSI-RS资源,依次类推,从而确定上报的N组测量上报值。
可见,在本公开实施例中可以将K组中所有的最大L1-RSRP或L1-SINR值所对应的CSI-RS资源作为一组测量上报值,即采用组间上报方式确定测量上报值;也可以将K组中任一组中最大L1-RSRP或L1-SINR值所对应的CSI-RS资源作为一组测量上报值,即采用组内上报方式确定测量上报值。很显然,本申请实施例提供了组内上报方式和组间上报方式的具体实施方式,增强了方案的可实施性。
在具体的实施过程中,上报的第z组CRI/SSBRI为第z个CSI-RS组中具有前M大L1-RSRP值的CSI-RS资源,n属于0-N中任一值,例如当N=K时,第一组上报值对应网络设备侧配置的第一个CSI-RS资源隐式组或CSI资源集即CSI-RS组中L1-SINR值较大的M个CSI-RS资源对应的CRI/SSBRI;第二组上报值对应网络设备侧配置的第二个CSI-RS组中L1-SINR值较大的M个CSI-RS资源对应的CRI/SSBRI;以此类推,直到确定第N组上报值对应网络设备侧配置的第N个CSI-RS组中L1-SINR值较大的M个CSI-RS资源对应的CRI/SSBRI。当N<K时,终端还可以选择L1-RSRP取值相对较大的N组上报。例如,按照组内最大L1-SINR排序选择N组,或者按照每组第M大L1-RSRP排序选择N组。本方法中的上报方法也可以叫组内上报。此时,需要求N<=K,M<=P。其中,P为不小于1的正整数。
在本申请实施例中还可以根据网络侧设备的指示信息,确定N组测量上报值;具体的,若确定指示信息为终端确定在CSI-RS组内进行测量值上报,则N组测量上报值包括基于对CSI-RS资源所对应的K个CSI-RS组所包括L1-RSRP或L1-SINR上报值进行从高到低的排序,所确定的每一组测量上报值所包含的CRI或SSBRI。
具体的,若指示信息为终端确定在CSI-RS组间进行测量值上报,则N组测量上报值包括基于CSI-RS资源所对应的单个CSI-RS组所包括L1-RSRP或L1-SINR上报值进行排序,并基于每个CSI-RS组的组内最大L1-RSRP或 L1-SINR值,所确定的每一组测量上报值所包含的CRI或SSBRI。
可选地,当网络侧设备没有配置或指示终端进行组内上报或组间上报,终端默认采用组间测量值上报,即按照前述进行上报。可选地,终端可以在上报时指示本次上报为组内上报或组间上报。
在本申请实施例中,终端还可以先确定满足条件的CSI-RS资源对,从而在确定的CSI-RS资源对中确定N组测量上报值。可选的,此步骤还可以在步骤101之前执行。在本申请实施例中,可以采用但不限于以下方式确定满足条件的CSI-RS资源对:
方式A:
在本申请实施例中,终端可以根据预定义的规则,确定不同CSI-RS资源组内的资源可被同时接收到;或者,同一CSI-RS资源组内的资源可被同时接收到,以确定可同时被接收的CSI-RS资源对的集合。
方式B:
在本申请实施例中,终端可以确定每个QCL-TypeD参数与终端接收空域滤波器的关联关系;其中,关联关系是终端基于之前测量结果确定的,并且,当在接收两个CSI-RS资源时,使用不同天线阵面或天线组来同时接收2个CSI-RS资源,且获得基于两个CSI-RS资源的QCL-TypeD参数以及关联关系所确定的预期的测量结果,则可以确定两个CSI-RS资源可以被同时收到,从而可以确定可同时被接收的CSI-RS资源对的集合。
方式C:
在本申请实施例中,当网络侧设备配置终端进行组间上报或者终端未收到网络侧设备的配置时,则确定进行组间上报,且终端在K个CSI-RS资源组间分别选择可同时收到的特定CSI-RS资源;或者,当网络侧设备配置终端进行组内上报,则终端在每个CSI-RS资源组内选择可同时收到的特定CSI-RS资源,以确定可同时被接收的CSI-RS资源对的集合。
例如,假设第一个CSI-RS资源隐式组或CSI资源集包含的波束(即CSI-RS资源)为[a1,a2,…,a4];第二个CSI-RS资源隐式组或CSI资源集包 含的波束(CSI-RS资源)为[b1,b2,…,b4]。
若终端确定进行组间上报,则根据终端实现或者网络侧设备的配置确定可以同时收到的组间波束对为:[a1,b1]、[a1,b2]、[a2,b1]、[a3,b3]、[a3,b4]、[a4,b2]、[a4,b4]。具体的,若根据预定义的规则可以确定任意两个组间波束对均可以同时收到,即至多4*4=16个波束对。此外,还可以认为[ai,bj]和[bj,ai]为不同的波束对,则此时终端可以同时收到的波束对的数值为以上确定的数值的2倍。
若终端确定进行组内上报,则根据终端实现或者网络侧设备的配置确定可以同时收到的组内波束对为[a1,a3]、[a1,a4]、[a2,a3]、[a2,a4]、[a3,a4]、[a4,a1]、[b1,b4]以及[b2,b4]。如果根据预定义的规则可以确定任意2个组内波束对均可以被同时收到,或者确定任意2个组内波束对均不能被同时收到,即0对。此外,还可以认为[ai,aj]和[aj,ai]为不同的波束对,[bi,bj]和[bj,bi]为不同的波束对。
在本申请实施例中,当确定可同时被接收的CSI-RS资源对集合后,可以基于可同时被接收的CSI-RS资源对集合,确定上报中包含的波束对(即CSI-RS资源对),使得上报的N组或N对波束对不完全相同。
在一种可能的实施方式中,终端可以将可同时被接收的CSI-RS资源对的集合中第s个L1-RSRP的CSI-RS资源,确定为第s组测量上报值中的第一个测量上报值;并将与第一个CSI-RS资源可同时被接收的CSI-RS资源对的集合中第s个L1-RSRP的CSI-RS资源,确定为第s组测量上报值中第二个测量上报值。
具体的,可以将可同时被接收的CSI-RS资源对的集合中,每一个第s组中的第一个测量上报值和第二个测量上报值,作为N组测量上报值;其中,s为基于L1-RSRP的值大小确定的顺序序号。
在具体的实施过程中,可以对L1-RSRP的值大小确定的顺序序号,其中,L1-RSRP的值可以是所有CSI-RS资源隐式组或CSI资源集内的CSI-RS资源上的L1-RSRP值的CSI-RS资源,也可以是限定是第一个CSI-RS资源隐式组 或CSI资源集中的CSI-RS资源上的L1-RSRP值,本申请实施例中不做限制。具体的,可以将L1-RSRP的值最大的顺序序号确定为1,将L1-RSRP的值次大的顺序序号确定为2,依次类推,确定L1-RSRP值所对应的顺序序号。
可见,当s为1时,第一组测量上报值即为L1-RSRP的值最大所对应的CSI-RS资源。也就是说,终端确定第一组测量上报值的第一个CSI-RS资源为可同时被接收的CSI-RS资源对的集合中具有最大L1-RSRP的波束,第二个CSI-RS资源为可以和第一个CSI-RS资源一起同时被终端接收的CSI-RS中具有最大L1-RSRP的波束,在确定第一组测量上报值后,在可同时被接收的CSI-RS资源对集合中删除该CSI-RS资源对。具体的,在确定第二组测量上报值时,所用方法和确定第一组测量上报值是相同的,但是删除第一组CSI-RS资源对后更新的可同时被接收的CSI-RS资源对集合所确定上报的第二组上报测量值,依次类推,从而可以确定上报测量值。
在一种可能的实施方式中,还可以确定可同时被接收的CSI-RS资源对的集合中,一个CSI-RS资源对中两个CSI-RS的L1-RSRP之和所对应的值从由高到低所确定的顺序值。然后按照顺序值,确定与顺序值一一对应的每一组测量上报值,并基于所有CSI-RS资源对所对应的测量上报值,确定N组测量上报值;其中,T为小于N的正整数。具体地,终端在集合S(S为满足条件的CSI-RS资源对)中选择一个CSI-RS资源对中2个CSI-RS的L1-RSRP之和最大的CSI-RS资源对作为第一组测量上报值,选择S中一个CSI-RS资源对中2个CSI-RS的L1-RSRP之和具有次大值的CSI-RS资源对作为第二组测量上报值,以此类推,直到选出N组测量上报对为止。
可见,在本申请实施例中,为了降低反馈开销,当确定的CSI资源对为[bj,ai]时,在实际上报时还可以将其调整为[ai,bj]。也即第一个CSI-RS资源来自具有较小的CSI-RS资源隐式组索引值或高层参数值,或者具有较小CSI资源集索引的CSI资源集。
也就是说,可以保证终端上报的N个CSI-RS资源对即测量上报值不完全相同,从而可以在一次上报中提供更多的波束信息,降低反馈开销。
在本申请实施例中,当确定N组测量上报值之后,可以根据N组测量上报值,确定N组测量值对应的差值,并基于差值确定N组测量上报值的上报格式,采用上报格式将N组测量上报值上报给网络侧设备。
在本申请实施例中,当确定N组测量上报值之后,可以确定N组测量值对应的差值,并根据差值确定N组测量上报值的上报格式为组内差分格式或组间差分格式。
在本申请实施例中,可以采用但不限于以下确定N组测量值对应的差值:
方式1:
在一示例性实施例中,确定N组测量上报值中每组测量上报值所包括的第2到第w个测量上报值均为与组内第一个测量上报值的差值,w为不小于2的正整数。
方式2:
在一示例性实施例中,确定N组测量上报值中第一组测量上报值为测量得到的L1-RSRP值或L1-SINR值;除第一组测量上报值外的第q组中的测量上报值的第r个测量上报值与第一组测量上报值中的第r个测量上报值的差值;r为0至w中的任一值。
方式3:
在一示例性实施例中,确定N组测量上报值中第一组中的第一个测量上报值为测量得到的L1-RSRP值或L1-SINR值,第一组中除第一个测量上报值之外的测量上报值,以及除第一组以外的测量上报值为与第一组测量上报值的第一个测量上报值的差值;其中,r为0至w中的任一值。
方式4:
在一示例性实施例中,确定N组测量上报值中第一组中的第一个测量上报值为测量得到的L1-RSRP值或L1-SINR值,以及除第一组中的第一个测量上报值外的其它测量上报值为与第一组测量上报值中的第一个测量上报值的差值;其中,r为0至w中的任一值。
在本申请实施例中,可以通过PUCCH(physical uplink control channel, 物理上行控制信道)或PUSCH(physical uplink shared channel,物理上行共享信道),将N组测量上报值以组内差分上报格式或组间上报格式上报给网络侧设备。
在具体的实施过程中,假设终端上报的测量上报值为4组,且每组包括2个测量值,即终端上报的8个L1-RSRP值分别是RSRP#1,RSRP#2,RSRP#3,RSRP#4,RSRP#5,RSRP#6,RSRP#7,RSRP#8;类似地,在L1-SINR上报中,8个上报值分别是SINR#1,SINR#2,SINR#3,SINR#4,SINR#5,SINR#6,SINR#7,SINR#8。
具体的,在差分上报中,一个或多个(例如最大的一个或多个)测量值采用直接上报的方式,即直接将前述一个或多个测量值上报,可以将该测量值称为非差分测量值,而除所述非差分测量值之外的其它测量值采用差分上报,可以将该测量值称为差分测量值。具体的,直接上报的测量值使用a比特进行量化,差分测量值采用b比特进行量化。例如a=7,b=4。
然而,在一次上报中,如果直接上报的测量值即非差分测量值和差分上报的测量值即差分测量值出现的位置不固定,基站将不能正确解读各个测量值。
例如,假设RSRP#1采用7比特量化,其它RSRP采用4比特量化,CRI/SSBRI共32比特,则终端在一次上报中上报67比特,则基站在收到终端上报的UCI后,可以确定前32比特代表CRI/SSBRI,例如每个CRI/SSBRI为4比特,共8个CRI/SSBRI,第33-39个比特对应RSRP#1,40-43比特对应RSRP#2,…以此类推。如果在某次上报中RSRP#2的测量值最大,且其采用的是直接上报的上报方式,而其它测量值采用差分上报的方式,基站仍然收到67比特,则按照Rel-15的方法进行解读,即认为前32比特代表CRI/SSBRI,第33-39个比特对应RSRP#1,40-43比特对应RSRP#2,…以此类推,这样的方式,导致错误地解读了RSRP#1和RSRP#2。
基于前述存在的问题,本申请实施例中在将N组测量上报值以差分上报的方式上报给网络侧设备时,例如以组内差分上报格式或组间上报格式,将N 组测量值上报给网络侧设备,还针对上报方式提供了相应的设计,从而使得基站可以正确解读上行控制信息,进而准确的获得N组测量上报值。
在本申请实施例中,可以采用但不限于以下方式进行差分上报:
方式1:
在本申请实施例中,当上报格式为组内差分时,上报N组测量上报值时,在UCI中增加的预设T比特指示一个组内非差分测量值出现的位置;非差分测量值用于表征一个组内最大测量值。
可选的,若确定上报格式为组内差分,即确定N组测量上报值中每组的第i个测量值外的测量值,均与组内的第i个测量值进行差分,i为大于或等于1的正整数。
具体的,N组测量上报值中每个组内的M个测量值分别对应K个CSI-RS资源组,当M=K时,每组的M个测量值与K个CSI-RS资源组一一对应。
在本申请实施例中,上报N组测量上报值时,可以在UCI中增加的预设T比特指示一个组内非差分测量值出现的位置。
具体的,预设T比特的T基于以下公式确定:
Figure PCTCN2022081497-appb-000001
其中,N用于表征测量上报值的组数,M用于表征每组测量上报值的个数,
Figure PCTCN2022081497-appb-000002
用于表征向上取整操作的运算符。
例如,当N=4,M=2时,即可以确定T为4,即在上行控制信息中增加4个比特,每个比特指示一个组内的非差分测量值出现的位置。例如,1和0分别表示非差分测量值出现在组内的第1个或第2个测量值上。又如,当N=4,M=4时,即可以确定T为8,即在上行控制信息中增加8个比特,每2个比特对应一个组内的非差分测量值的出现位置,即一个码点(00,01,10或11)对应一个出现位置。
在本申请实施例中,增加的T比特的位置可以在CRI/SSBRI和/或L1-RSRP/L1-SINR之后,或者之前,或者出现在每一组上报的CRI之前或之后,或者出现在每一组上报的L1-RSRP/L1-SINR之前或之后都可以,本申请 实施例不做限定。
例如,增加的T的比特出现在CRI/SSBRI和/或L1-RSRP之前,当N=4,M=2时,上报的格式请参阅表1:
Figure PCTCN2022081497-appb-000003
表1
其中,编号#1和#2为第一组,#3和#4为第二组,#5和#6为第三组,#7和#8为第四组,每个比特指示一个组内的差分测量值出现的位置。例如,差分测量值出现位置指示为0110,则可以确定第一组中的第二个测量值,第二组中的第一个测量值,第三组中的第一个测量值和第四组中的第二个测量值为差分测量值,即对应RSRP#2,RSRP#3,RSRP#5,RSRP#8。
方式2:
在本申请实施例中,上报N组测量上报值时,在UCI中增加的预设T比特指示一个组内差分测量值出现的位置,其中,所述T基于测量上报值的组数以及每组测量上报值的个数对应确定。
可选的,当确定N组测量上报值中每组的第j个测量值(除第i组外)与第i组的第j个测量值进行差分,其中j=1,2,…,M;i=1,2,…,N。
在本申请实施例中,可以基于以下公式确定T:
Figure PCTCN2022081497-appb-000004
其中,N用于表征测量上报值的组数,M用于表征每组测量上报值的个数,
Figure PCTCN2022081497-appb-000005
用于表征向上取整操作的运算符。
与方式1中方法类似,增加
Figure PCTCN2022081497-appb-000006
比特表示差分测量值出现位置,增加的比特可以出现在CRI/SSBRI和/或L1-RSRP/L1-SINR之后。例如,当N=2,M=2时,则可以确定第一预设个数为2,即增加了2比特,且这两个比特分别代表第1个测量值和第2个测量值针对哪个组做差分。进一步地,当确定增加了2个比特,且若2个比特中的一个比特为0,另一个比特为1,则其中,比特为0表示针对第一组做差值,比特为1表示针对第二组做差值;当2个比特为均0时,表示每组的第一个测量值均针对第一组的第一个测量值做差分,每组的第2个测量值均针对第一组的第2个测量值做差分。
又如,当N=4,M=2,则可以确定第一预设个数为4,即增加了4比特,且该比特也分别代表第1个和第2个测量值针对哪个组做差分,例如以每2个比特表示一个测量值的差分位置。如4比特分别为0110,则可以确定01表示第一个测量值针对第2组做差分,10表示第二个测量值针对第3组做差分。
方式3:
在本申请实施例中,当上报格式为组间差分时,上报N组测量上报值时,在UCI中增加的T比特指示差分测量值出现的位置;差分测量值用于表征一个组内除最大测量值外的测量值。
具体的,组间差分具体为第一组的第一个测量值以外的测量值,以及除第一组外的测量值,均与第一组的第1个测量值进行差分。以及,该组间差分方式可以进一步扩展为:第一组的第一个测量值以外的测量值,以及除第一组外的测量值,均与第一组的第2个测量值进行差分。
例如,T为1,则当该比特为0时,表示针对第一组的第2个测量值进行差分,该比特为1时,表示针对第一组的第1个测量值进行差分。
需要说明的是,上述方式1、方式2以及方式3的实施中,每组测量上报 值和CSI-RS资源组有固定的关联关系,即在L1-RSRP上报时,多个L1-RSRP值始终按照固定的顺序排列,例如前面提到的N=4,M=2时,RSRP#1,RSRP#2,RSRP#3,RSRP#4,RSRP#5,RSRP#6,RSRP#7,RSRP#8分别对应第1,2,1,2,1,2,1,2个CSI-RS资源组,类似的,CRI/SSBRI或L1-SINR也是值始终按照固定的顺序排列。
方式4:
在本明实施例中,当上报格式为组内差分或组间差分时,上报N组测量上报值时,在UCI中的预设个数的比特中指示测量值与CSI-RS资源组的关联关系;或者,用于指示对应的CSI-RS资源组是否调换顺序。
示例性的,预设个数的比特可以基于确定T比特的方式确定,例如,N=4,M=2时,则可以确定第二预设个数为8,具体的,可以用比特映射(bitmap)的方式指示每个测量值或CRI/SSBRI与2个CSI-RS资源组(如CSI resource set)的关联关系,如0表示第一个CSI-RS资源组,1表示第二个CSI-RS资源组。例如,对于组内差分,01100110表示上报的8个测量值分别对应第1、2、2、1、1、2、2、1个CSI-RS资源组。
仍然以N=4,M=2为例,当采用组内差分时,可以每组采用1比特指示该组的测量值是否换顺序,如‘1’表示顺序调换,‘0’表示顺序未调换。例如,原本每组2个测量值分别对应第一个和第二个CSI-RS资源组,如果指示调换顺序,则表示目前第一个测量值为第二个CSI-RS资源组,而第二个测量值对应第一个CSI-RS资源组。在这种情况下,组内的L1-RSRP或L1-SINR始终按照从大到小的顺序排列。
具体的,对于组间差分,也可以用1比特指示第一组的2个测量值是否调换顺序,方法和组内差分是类似的,由于其他组均为针对第一组一个测量值的差分测量值,无需换序,因此这种方式无需为其它组指示顺序调换情况。
在实际实施过程中,请参阅表2,表2示出了多种上报方法的UCI开销对比,其中,其中K表示每个CSI-RS资源组中的CSI-RS资源或SSB资源的数量,一个CSI-RS资源组可以是一个CSI resource set。
Figure PCTCN2022081497-appb-000007
表2
从表2可以看出,在多TRP场景下支持基于组的波束上报后,相比现有技术的UCI负载显著增加,因此,本申请实施例还提供了降低上行控制信息负载的方案。
在本申请实施例中,可以确定上报N组测量值中每个差分测量值或每个测量值的上报比特数,然后可以基于上报比特数和预设上报规则,将N组测量值上报给网络侧设备。
可选的,可以考虑节省L1-RSRP或L1-SINR开销,来降低UCI负载。示例性的,每个差分测量值在上报时采用更低的开销,即由现有的4比特可以降低为0,1,2或3比特,即上报N组测量值中每个差分测量值的上报比特数可以为0,1,2或3比特。具体的,上报N组测量值中每个差分测量值的上报比特数降低为几个比特可以在协议中预先规定,或者由高层信令配置,或者由终端自行决定,本申请实施例中不做限定。
示例性的,差分测量值采用0比特上报,也就是说,在上报时仅上报直接测量值,差分测量值不进行上报,即上报N组测量值中每个差分测量值的上报比特数降为0比特。即当N=4,M=2时,当采用组内差分时,每组中一个波束(采用差分形式上报的波束)只上报CRI/SSBRI,而不上报对应的L1-RSRP或L1-SINR。
示例性的,差分测量值采用1比特上报。也就是说,在上报时仅上报直接测量值,差分测量值仅上报1个测量值,即上报N组测量值中每个差分测量值的上报比特数降为1比特。在采用组内差分时,每组第2到M个波束(CRI/SSBRI),或者L1-RSRP或L1-SINR取值第2大到第M大的波束,对应的L1-RSRP或L1-SINR采用更粗的粒度上报(如1比特),如果第二个波束和第一个波束的差距在XdB内,第二个波束为1,否则为0;反过来也是可以的,例如差距在XdB内,第二个波束为0,否则为1。
这样,相比之前采用差分上报的形式,每个差分的波束对应的测量值可以减少3比特开销。此外,X可以在协议中预先定义好的值,如8dB,还可以是RRC信令配置的值,本申请实施例中不做限制。
示例性的,差分测量值采用2或3比特上报,也就是说,即上报N组测量值中每个差分测量值的上报比特数降为2或3比特。此时可以配置或预定义Y个差值,或者门限值,如果差分测量值落在哪个区间则上报相应的值。
例如,上报N组测量值中每个差分测量值的上报比特数为2,定义2个差值分别是Y1和Y2,参阅表3,表3为上报N组测量值中每个差分测量值的上报比特数为2所对应确定的上报值。
Figure PCTCN2022081497-appb-000008
表3
又如,上报N组测量值中每个差分测量值的上报仍然为2比特,定义3个差值分别是Y1、Y2和Y3,参阅表4,表4为上报N组测量值中每个差分测量值的上报比特数为3所对应确定的上报值。
Figure PCTCN2022081497-appb-000009
表4
又如,上报N组测量值中每个差分测量值的上报为3比特,可以定义至多7个差值(或门限)分别是Y1、Y2、Y3、Y4、Y5、Y6、Y7,参阅表5,表5为上报N组测量值中每个差分测量值的上报比特数为3所对应确定的上报值。
Figure PCTCN2022081497-appb-000010
表5
可选的,还可以考虑降低CRI/SSBRI的开销,来降低UCI的负载。例如2个波束的gap大于ZdB时,只上报第一个CRI,否则上报2个CRI。Z可以 在协议中预先定义好的值,如8dB,还可以是RRC信令配置的值,本申请实施例中不做限定。当差距过大时,则表示采用差分形式上报的波束质量较差,无法为终端提供服务,因此可以不上报相应的CRI/SSBRI。类似地,对应的L1-RSRP或L1-SINR也可以不上报。
为了便于本领域技术人员理解,以下列举几种可能的方式来说明测量上报的技术方案,应该理解的是,以下举例只是示意性的说明,其并不对本申请实施例构成限定,除去以下所列举的方式,在具体实施过程中还可以再采用其它的方式,本文中并不穷举。
实施例一:
在本实施例中,若网络侧设备为终端配置一个CSI资源集合,且CSI资源集合包括多个CSI资源集,每个CSI-RS资源集合包含多个CSI-RS资源组,每个CSI资源集对应1个TRP。也就是说,实施例一以一个CSI reporting setting,即CSI上报集合和一个CSI资源集合为例进行说明。
在一种可能的实施方式中,CSI资源集合可以包含多个CSI-RS资源,每个CSI-RS资源在配置时包括与其对应的TRP相关的高层参数,例如,CSI-RS资源中包含高层参数CORESETPoolIndex,或者组索引,或者其它高层参数,或者物理小区索引(physical cell ID)。
需要说明的是,该高层参数的取值至多有K个,即隐式地将CSI-RS资源分为K组,每组P个CSI-RS资源。例如,K的取值例如是2,表示2个TRP。此时,K个CSI-RS资源隐式组可以包含在一个CSI资源集合中。在这种隐式分组下,还支持在一个CSI-RS资源中配置两个或以上TRP相关的高层参数,例如配置2个组索引,又或者包含一个高层参数的2个或以上取值,例如参数CORESETPoolIndex取值为0和1。即这样的表述方式可以表示一个CSI-RS资源和2个或以上TRP关联,例如TRP1和TRP2均在此CSI-RS资源上发送参考信号。可选地,可以为此CSI-RS资源配置2个或以上QCL-TypeD参数。
此外,还需要说明的是,在本申请所有实施例中,均可以假设每组CSI-RS资源的数量是相等的,该假设仅仅为了便于描述,也就是说,本申请中的方 法也可以扩展到每组CSI-RS资源数不相等的情况。
在本申请实施例中,若网络侧设备配置终端进行L1-RSRP测量上报,则终端可以根据以下方法确定终端的测量上报行为:
步骤a:终端根据网络侧设备配置,确定每个CSI-RS资源上QCL-TypeD参数,根据确定的QCL-TypeD参数接收CSI-RS,并测量确定每个CSI-RS的接收功率,以确定L1-RSRP值。
在本申请实施例中,在测量每个CSI-RS资源对应的L1-RSRP值时,终端可以将每个CSI-RS资源组用于信道测量,从而可以直接根据用于信道测量的CSI-RS组中,网络侧设备预先为每个CSI-RS资源配置的QCL-TypeD参数,对CSI-RS资源进行接收,从而可以测量确定每个CSI-RS的接收功率,以确定L1-RSRP值。
在本申请实施例中,CSI资源集还包括其它CSI-RS的显式分组,具体的显示分组例如是一个CSI资源集合显式地配置2个CSI资源集,或者一个CSI资源集合包含2个CSI资源子集(即resource subset),或者一个CSI资源集包含2个CSI资源子集(即CSI resource subset)等等,本申请实施例中不做限制。
在该实施例中,在测量每个CSI-RS资源对应的L1-RSRP值时,终端将每个CSI-RS资源隐式组或CSI资源集用于信道测量。
步骤b:终端确定N组测量上报值中包含的CRI或SSBRI。
在本申请实施例中,当终端确定L1-RSRP值后,可以基于L1-RSRP值确定N组测量上报值中包含的CRI或SSBRI。
具体的,确定测量上报值的方式可以参见步骤102中所描述的组间上报方式和组内上报方式确定测量上报值,这里不再赘述。
在具体的实施过程中,若一个CSI-RS资源和多个CSI-RS资源隐式组或CSI资源集关联,例如和第1个和第2个CSI-RS资源隐式组或CSI资源集关联,则该CSI-RS资源对应的测量结果在上报时可以出现在每组测量结果的第1和第2个位置上。
步骤c:终端确定N组测量上报值中CRI或SSBRI对应的L1-RSRP测量值。
在本申请实施例中,在通过步骤a和步骤b确定哪些波束(CRI或SSBRI)对应的L1-RSRP需要上报以后,对其测量值进行量化上报。其中部分测量值采用直接量化上报方式,另外的测量值采用和其它未量化的测量值的差分量化进行上报。
可以从上报的N组测量值中,确定每组第2到第w个测量值均为与组内第一个测量值的差值,其中,w为不小于2的正整数。
在一种可能的实施方式中,在上报的N组测量值中,确定N组测量上报值中第一组测量上报值为测量得到的L1-RSRP值或L1-SINR值;除第一组测量上报值外的第q组的测量上报值的第r个上报值与第一组测量上报值的第r个测量上报值的差值。可见,若采用组间上报方式,则可以理解为在每个TRP上报的多个波束之间执行差分。
在一种可能的实施方式中,在上报的N组测量值中,确定N组测量上报值中第一组中的第一个测量上报值为测量得到的L1-RSRP值或L1-SINR值,第一组的除第一个测量上值之外的上报值,以及除第一组以外的上报值为与第一组测量上报值的第1上报值的差值;其中,r为0至w中的任一值。
在一种可能的实施方式中,确定N组测量上报值中第一组中的第一个测量上报值为测量得到的L1-RSRP值或L1-SINR值,以及除第一组中的第一个测量上报值外的其它上报值为与第一组测量上报值的第1个测量上报值的差值;其中,r为0至w中的任一值。
步骤d:终端通过PUCCH或PUSCH,将N组测量上报值中CRI或SSBRI对应的L1-RSRP测量值上报给网络侧设备。
需要说明的是,在本申请实施例中,若网络侧设备配置终端进行L1-SINR测量上报,可以将以上所有步骤中的L1-RSPR替换成L1-SINR即可实现。
实施例二:
在本实施例中,CSI上报集合和CSI资源集合的配置和实施例1是相同的, 即网络侧设备为终端配置1个CSI上报集合,此CSI上报集合对应1个CSI资源集合。该CSI资源集合包含K个CSI resource set即CSI资源集即K个CSI-RS组,每个CSI资源集包含P个CSI-RS资源,每个CSI资源集对应1个TRP,即由对应的TRP发出或者用于终端测量对应的TRP的信道或干扰。或者,该CSI资源集合包含K*P个CSI-RS资源,每个CSI-RS资源在配置时有一个TRP相关的高层参数,例如在CSI-RS资源中包含高层参数CORESETPoolIndex,或者组索引,或者其它高层参数,此高层参数的取值至多有K个,即隐式地将CSI-RS资源分为K组,每组P个CSI-RS资源。K的典型取值例如是2,表示2个TRP。在这种隐式分组下,还支持在一个CSI-RS资源中配置两个或以上TRP相关的高层参数,例如配置2个组索引,又或者包含一个高层参数的2个或以上取值,例如参数CORESETPoolIndex取值为0和1。在这种情况下,表示一个CSI-RS资源和2个或以上TRP关联,例如TRP1和TRP2均在此CSI-RS资源上发送参考信号。可选地,可以为此CSI-RS资源配置2个或以上QCL-TypeD参数。
在实施例中,终端上报的L1-SINR是将每个CSI-RS资源隐式组或CSI资源集用于信道测量和干扰测量。也即一个CSI-RS资源隐式组或CSI资源集既用于信道测量又可以用于干扰测量。此时测出的干扰情况为终端经历的干扰的集合,也即所有干扰。本实施例给出一种测量特定干扰(例如小区间或TRP间的干扰)的测量方法。需要说明的是,在本申请实施例中,一个CSI-RS资源隐式组或CSI资源集简称为一个CSI-RS组。
请参见附图2,图2为以CSI-RS组1和CSI-RS组2分别和TRP1和TRP2关联为例,也即TRP1在CSI-RS组1中的CSI-RS资源上发送参考信号,TRP2在CSI-RS组2中的CSI-RS资源上发送信号。
在具体的实施过程中,TRP1在CSI-RS组1中的CSI-RS资源上发送参考信号的同时会对终端接收TRP2上的信号产生干扰,类似地,TRP2在CSI-RS组2中的CSI-RS资源上发送参考信号的同时会对终端接收TRP1上的信号产生干扰。因此,在进行L1-SINR测量时,终端可以根据CSI-RS组1来进行 TRP1的信道测量和TRP2的干扰测量;以及,根据CSI-RS组2来进行TRP2的信道测量和TRP1的干扰测量。
在本实施例中,具体的测量上报方法为:
步骤f:终端根据网络侧设备配置确定每个CSI-RS资源上QCL-TypeD参数,根据确定的QCL-TypeD参数接收CSI-RS,并测量确定每个CSI-RS的接收功率,以确定L1-SINR值。
具体的,可以采用但不限于以下两种方式确定L1-SINR值:
方式一:
在本实施例中,以K=2为例,网络侧设备为CSI-RS组1和CSI-RS组2中的每个CSI-RS资源配置2个QCL-TypeD参数,假设第一个QCL-TypeD参数表示CSI-RS资源在用于信道测量时的QCL,假设第二个QCL-TypeD参数表示CSI-RS资源在用于干扰测量时的QCL。
在具体的实施过程中,终端可以将CSI-RS组1用于信道测量,CSI-RS组2用于干扰测量,此时可以测出TRP2对TRP1的干扰。具体地,假设CSI-RS组1中的CSI-RS资源数量和CSI-RS组2中的CSI-RS资源数量是相等的。
需要说明的是,在本申请所有实施例中,CSI-RS资源包括NZP(Non-zero Power非零功率CSI-RS资源和SSB(Synchronization Signal Block,同步信号块)。
在具体的实施过程中,针对CSI-RS组1中的一个CSI-RS资源,在测量时,终端可以使用CSI-RS该资源上网络侧设备配置的第一个QCL-TypeD来接收并测量该CSI-RS资源,作为第一个CSI-RS组对应的TRP的一个信道测量值(例如标记为M1)。与此同时,可以使用网络侧设备配置的第二个QCL-TypeD参数来接收测量该CSI-RS资源,作为第二个CSI-RS组对应的TRP的一个干扰测量值(例如标记为M2)。
在具体的实施过程中,采用相同或相似的方式,针对CSI-RS组2中的一个对应CSI-RS资源,也即与CSI-RS组1中的测量的CSI-RS资源相对应的CSI-RS资源。在测量时,终端使用该CSI-RS资源上网络侧设备配置的第一个QCL-TypeD来接收并测量该CSI-RS资源,作为第二个CSI-RS组对应的 TRP的一个信道测量值(例如标记为M3)。与此同时,使用网络侧设备配置的第二个QCL-TypeD参数来接收测量该CSI-RS资源,作为第一个CSI-RS组对应的TRP的一个干扰测量值(例如标记M4)。
在本实施例中,当终端在测量第一个CSI-RS组对应的TRP上的L1-SINR值时,使用测量值M1和M4,为了可以基于M4更准确确定干扰情况,可以假设测量信道和测量干扰时的QCL-TypeD参数相同,也即CSI-RS组2中CSI-RS的第二个QCL-TypeD参数,和CSI-RS组1中对应的CSI-RS的第一个QCL-TypeD参数配置成相同值。
具体的,采用相同的方式,当终端在测量第二个CSI-RS组对应的TRP上的L1-SINR值时,使用测量值M3和M2,为了可以基于M2更准确的确定干扰情况,可以假设测量信道和测量干扰时的QCL-TypeD参数相同,也即CSI-RS组1中一个CSI-RS的第二个QCL-TypeD参数,和CSI-RS组2中对应的CSI-RS的第一个QCL-TypeD参数配置成相同值。
需要说明的是,在本申请所有实施例中,在进行L1-SINR测量时,若CSI-RS组为CSI资源集或者显式配置的CSI-RS组,则对应的CSI-RS资源指的是2个CSI资源集配置中具有相同顺序值的2个CSI-RS资源。例如,第一个CSI-RS资源集中配置的第4个CSI-RS资源和第二个CSI-RS资源集中配置的第4个CSI-RS资源是对应的。具体的,若CSI-RS组为CSI-RS资源隐式组,对应的CSI-RS资源指的是2个隐式组中CSI-RS资源按照索引值由低到高排序后,具有相同顺序值的2个CSI-RS资源。所述2个CSI-RS资源隐式组,指的是同一个CSI资源集合中的2个CSI-RS资源隐式组,也可以是不同的CSI资源集合中的2个CSI-RS资源隐式组。
方式二:
同样以K=2为例,网络侧设备为CSI-RS组1和CSI-RS组2中的每个CSI-RS资源配置1个QCL-TypeD参数,在测量每个CSI-RS资源时,终端使用网络侧设备配置的QCL-TypeD参数用来进行信道测量,同时使用一个预定义的QCL-TypeD参数来进行干扰测量。
在本实施例中,终端可以将CSI-RS组1用于信道测量,CSI-RS组2用于干扰测量,则可以测出TRP2对TRP1的干扰。具体地,假设CSI-RS组1中的CSI-RS资源数量和CSI-RS组2中的CSI-RS资源数量是相等的。
在本实施例中,针对CSI-RS组1中的一个CSI-RS资源,在测量时,终端使用该资源上网络侧设备配置的QCL-TypeD来接收并测量该CSI-RS资源,作为第一个CSI-RS组对应的TRP的一个信道测量值(例如标记为M1)。与此同时,使用CSI-RS组2中对应的CSI-RS资源配置的QCL-TypeD参数来接收测量该CSI-RS资源,作为第二个CSI-RS组对应的TRP的一个干扰测量值(例如标记为M2)。
具体的,采用相同的方式,针对CSI-RS组2中的对应的CSI-RS资源,也即与CSI-RS组1中的测量的CSI-RS资源相对应的CSI-RS资源。在测量时,终端使用该资源上网络侧设备配置的QCL-TypeD来接收并测量该CSI-RS资源,作为第二个CSI-RS组对应的TRP的一个信道测量值(例如标记为M3)。与此同时,使用CSI-RS组1中对应的CSI-RS资源配置的QCL-TypeD参数来接收测量该CSI-RS资源,作为第一个CSI-RS组对应的TRP的一个干扰测量值(例如标记为M4)。
具体的,当终端在测量CSI-RS组1对应的TRP上的L1-SINR值时,使用测量值M1和M4共同确定L1-SINR值。以及,当终端在测量CSI-RS组2对应的TRP上的L1-SINR值时,使用测量值M3和M2共同确定L1-SINR值。
在本实施例中,网络侧设备还可以配置或指示终端在测量时的一些假设或限制,例如使用相同或不同的panel来接收2个CSI-RS资源隐式组或CSI资源集或CSI-RS资源;或者使用相同或不同的空间接收滤波器来接收2个CSI-RS资源隐式组或CSI资源集或CSI-RS资源;或者指示终端在测量CSI-RS组1时将CSI-RS组2进行叠加处理还是做干扰处理,类似地,可以指示终端在测量CSI-RS组2时将CSI-RS组1进行叠加处理还是做干扰处理。
在网络侧设备配置或不配置以上假设或限制的情况下,终端还可以在上报测量结果的同时上报以上测量假设或限制。
步骤g:终端确定N组测量上报值中包含的CRI或SSBRI。
在本实施例中,终端根据实施例一中的步骤b中的方法确定上报的N组测量值中包含的CRI或SSBRI,这里不再赘述。
步骤h:终端确定N组测量上报值中CRI或SSBRI对应的L1-RSRP测量值。
在本实施例中,终端根据实施例一中的步骤c中的确定差值的方式确定测量值,具体的,可以将实施例一中的步骤c中的L1-RSRP替换为L1-SINR进行处理,这里不再赘述。
步骤i:终端通过PUCCH或PUSCH,将N组测量上报值中CRI或SSBRI对应的L1-RSRP测量值上报给网络侧设备。
实施例三:

在本实施例中,网络侧设备为终端配置1个CSI上报集合,此CSI上报集合对应2个CSI资源集合,每个CSI资源集合包含K个CSI-RS组(显式组或隐式组),且仅用于L1-SINR的上报。
