应理解,本发明实施例的技术方案可以应用于各种通信系统,例如:长期演进(Long Term Evolution,LTE)系统、LTE频分双工(Frequency Division Duplex,FDD)系统、LTE时分双工(Time Division Duplex,TDD)、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)或全球互联微波接入(Worldwide Interoperability for Microwave Access,WiMAX)通信系统、5G系统,或者说新无线(New Radio,NR)系统,或者为后续演进通信系统。

如图1所示,本发明的一个实施例提供一种传输波束报告的方法100,该方法可以由移动终端执行,换言之,该方法可以由安装在移动终端的软件或硬件来执行,该方法包括如下步骤:
S104:移动终端分别向多个第一发射接收点发送对应的第一波束报告。
在多TRP(MTRP)场景中,CSI报告配置(CSI-ReportConfig)中基于组的波束报告(groupBasedBeamReporting)设置为“使能(enable)”时,进行增强。其中,MTRP场景的配置有多种方式,例如控制资源集(COntrol REsource SET,CORESET)的控制资源集池索引(CORESETPoolIndex)的有多个值、或至少1个非零值,又例如下行控制信息(DCI)指示的传输配置指示码点包含多个传输配置指示状态,又例如网络配置了其它小区或TRP的标识信息,在此不一一列举。TRP的标识信息,可以为CORESETPoolIndex,也可以为物理小区标识,或其它表征TRP的标识。当网络配置多个CORESETPoolIndex时,相同CORESETPoolIndex的控制资源集,属于同一个TRP。
移动终端可以分别向多个第一发射接收点发送对应的第一波束报告,其中,所述第一波束报告为所述第一发射接收点对应的参考信号的报告。例如,对于每个TRP,UE上报一个参考信号(Reference Signal,RS),例如最优的波束。波束,又可称为空域滤波器(spatial domain filter),空域接收滤波器(spatial domain receive filter),空域发送滤波器(spatial domain transmit filter)。第一发射接收点与RS的对应关系,可以通过网络进行配置或者UE进行上报。其中网络配置可以有多种实现方法,例如网络给RS配置TRP标识信息;又例如网络为TRP配置RS列表或传输配置指示(Transmission Configuration Indicator,TCI)列表,该RS列表或TCI列表中的RS即为TRP对应的RS;又例如该TRP对应的CORESET通过激活RS、配置RS等方式与RS关联,如激活RS的信令或配置RS的信令或将RS与CSI报告关联的信令由该CORESET对应的物理下行共享信道(Physical Downlink Shared Channel,PDSCH)发送,又如包含RS质量的CSI报告的上报由该CORESET触发的上行信道发送,这些关联的RS即为TRP对应的RS;在此不一一列举。
第一发射接收点接收对应的第一波束报告后,可以基于第一波束报告确定第一发射接收点用来向UE发送信道或信号的波束。在一种实现方式中, 所述第一波束报告和/或所述基于组的波束报告中的报告量为CSI-RS资源指示-信噪比(CSI-RS Resource Indicator-SINR,CRI-SINR)或ssb-Index-SINR或SRS资源指示(SRS resource indicator,sri)-SINR时,所述报告量的测量基于所述第一波束报告中的参考信号。在经过波束测量和波束报告后,网络可以基于报告量,对下行与上行链路的信道或参考信号做波束指示,用于网络与UE之间建立波束链路,实现信道或参考信号的传输。
例如,在存在TRP1、TRP2……TRPn的场景中,UE向TRP1发送TRP1对应的第一波束报告,TRP1对应的第一波束报告为TRP1对应的参考信号的报告。UE向TRP2发送TRP2对应的第一波束报告,TRP2对应的第一波束报告为TRP2对应的参考信号的报告……向TRPn发送TRPn对应的第一波束报告,TRPn对应的第一波束报告为TRPn对应的参考信号的报告,即只需要将某个TRP有关的波束上报给该TRP。
相比于移动终端向多个第一发射接收点均发送基于组的波束报告,所述基于组的波束报告中包含多个第一发射接收点对应的参考信号的报告的解决方案,即向TRP1、TRP2……TRPn均发送基于组的波束报告,所述基于组的波束报告中包含TRP1、TRP2……TRPn中所有参考信号的报告。本步骤可以在保证收发性能的基础上,节约波束报告的开销。
本发明的一个实施例提供一种传输波束报告的方法,通过分别向多个第一发射接收点发送对应的第一波束报告,其中,所述第一波束报告为所述第一发射接收点对应的参考信号的报告,能够在保证收发性能的基础上,节约波束报告的开销。
如图2所示,本发明的一个实施例提供一种传输波束报告的方法200,该方法可以由移动终端和/或网络设备执行,换言之,该方法可以由安装在移动终端和/或网络设备的软件或硬件来执行,该方法包括如下步骤:
S202:移动终端接收所述多个第一发射接收点对应的一个或多个波束报告配置,移动终端对所述参考信号信息对应的参考信号进行测量,生成第一 发射接收点对应的第一波束报告。
一种情况中,多个第一发射接收点中的一个向所述移动终端发送多个第一发射接收点对应的一个或多个波束报告配置,其中,所述波束报告配置中包括多个所述第一发射接收点对应的参考信号信息。另一种情况中,多个第一发射接收点分别向移动终端发送多个第一发射接收点对应的多个波束报告配置,其中,所述波束报告配置中包括所述第一发射接收点对应的参考信号信息;然后其中一个发射接收点发送关联信令,来确定多个所述波束报告配置之间的关联关系。移动终端接收所述多个第一发射接收点对应的一个或多个波束报告配置。
在一种实现方式中,第一发射接收点向所述移动终端发送一个波束报告配置,一个所述波束报告配置中包含多个所述第一发射接收点对应的参考信号信息,即一个所述波束报告配置中包含TRP1、TRP2……TRPn对应的参考信号信息。移动终端对所述参考信号信息对应的参考信号进行测量得到基于组的波束报告,所述基于组的波束报告中包含TRP1、TRP2……TRPn中所有参考信号的报告,对该基于组的波束报告进行拆分得到TRP1、TRP2……TRPn分别对应的第一波束报告。
在另一种实现方式中,第一发射接收点向所述移动终端发送L个波束报告配置,L大于1,一个所述波束报告配置中包含一个所述第一发射接收点对应的参考信号信息,即L与TRP的个数N相等。例如,N=2,L=2。移动终端对L个波束报告配置中包含的参考信号进行测量得到基于组的波束报告,所述基于组的波束报告中包含TRP1、TRP2……TRPn中所有参考信号的报告,对该基于组的波束报告进行拆分得到TRP1、TRP2……TRPn分别对应的第一波束报告。
在另一种实现方式中,第一发射接收点向所述移动终端发送L个波束报告配置,L大于1但小于TRP的个数N,即L个波束报告配置中有L1个波束报告配置中包含一个所述第一发射接收点对应的参考信号信息,有L2个 波束报告配置中包含多个所述第一发射接收点对应的参考信号信息,L1+L2=L。终端对该L1个波束报告配置中包含的参考信号和L2个波束报告配置中包含的参考信号进行测量得到基于组的波束报告,并对该基于组的波束报告进行拆分得到TRP1……TRPn分别对应的第一波束报告。
S204:移动终端分别向多个第一发射接收点发送对应的第一波束报告。
在多TRP场景中,移动终端可以分别向多个第一发射接收点发送对应的第一波束报告,其中,所述第一波束报告为所述第一发射接收点对应的参考信号的报告。第一发射接收点接收对应的第一波束报告后,可以基于第一波束报告确定第一发射接收点用来向UE发送信道或信号的波束。
在一种实现方式中,在所述波束报告配置为一个的情况下,所述波束报告配置中包含多个波束报告资源,所述波束报告资源对应于一个或多个所述第一发射接收点,在所述波束报告资源上,发送所述波束报告资源对应的第一发射接收点的第一波束报告。
在另一种实现方式中,在所述波束报告配置为多个的情况下,所述波束报告配置中包含一个或多个波束报告资源,所述波束报告资源对应于一个或多个所述第一发射接收点,在所述波束报告资源上,发送所述波束报告资源对应的第一发射接收点的第一波束报告。
在一种实现方式中,在所述波束报告配置包含多个所述波束报告资源的情况下,通过物理上行控制信道(Physical Uplink Control Channel,PUCCH)、物理上行共享信道(Physical Uplink Shared Channel,PUSCH)、空间相关信息、TCI、和TCI的码点中的至少一种对多个所述波束报告资源进行区分,来得到一个或多个所述第一发射接收点对应的波束报告资源。例如,配置中包含多个空间相关信息,或空间相关信息配了多个RS,或配了多个TCI,或TCI配了多个码点(code point),每个code point包含一个或数个RS。
在一种实现方式中,在所述波束报告配置包含多个所述波束报告资源的情况下,本步骤可以包括:轮流在多个所述波束报告资源中的部分波束报告 资源上发送所述第一发射接收点对应的第一波束报告。例如L个波束报告资源轮流发送,第一个周期在第一个波束报告资源发送对应的波束报告,第二个周期在第二个波束报告资源发送对应的波束报告,以此类推。
在一种实现方式中,在移动终端支持同时发送的情况下,同时发送所述第一发射接收点对应的第一波束报告。例如,这L个波束报告中的L3个波束报告的空域资源不同,当UE支持多波束同时发送时,UE可以同时将这L3个波束报告资源对应的多个波束报告分别发送至多个TRP,其中L3小于等于L。可选的,空域资源不同,可以为空间相关信息不同,或空间相关信息配了多个RS,或配了多个TCI,或TCI配了多个code point,每个code point包含一个或数个RS。
在一种实现方式中,在所述波束报告配置包含一个所述波束报告资源的情况下,所述方法还包括:共享频域资源并且对时域资源进行分割以将一个波束报告资源划分为多个所述波束报告资源。例如,L个波束报告资源配置在一起,即实际网络只配置了一个波束报告资源,网络和/或UE将其拆分为L个。其中,可以在频域资源上共享在时间上分割,例如在时间上均匀分割。即总时间资源为T,则时间资源的前T/L为第一个波束报告资源,T/L~2*T/L为第二个波束报告资源,以此类推。
在一种实现方式中,在所述波束报告配置为多个的情况下,通过关联信令确定多个所述波束报告配置之间的关联关系。例如,网络可以配置额外的信令来关联所述多个所述波束报告配置。
本发明的一个实施例提供一种传输波束报告的方法,通过分别向多个第一发射接收点发送对应的第一波束报告,其中,所述第一波束报告为所述第一发射接收点对应的参考信号的报告,能够在保证收发性能的基础上,节约波束报告的开销。
本发明的一个实施例提供一种传输波束报告的方法,通过接收所述多个第一发射接收点对应的一个或多个波束报告配置,其中,所述波束报告配置 中包括多个所述第一发射接收点对应的参考信号信息;对所述参考信号信息对应的参考信号进行测量,得到所述第一发射接收点对应的第一波束报告,为实现在保证收发性能的基础上节约波束报告的开销,设计了合理的信令配置。
本发明的一个实施例提供一种传输波束报告的方法,通过在所述波束报告配置为一个的情况下,所述波束报告配置中包含多个波束报告资源,或者在所述波束报告配置为多个的情况下,所述波束报告配置中包含一个或多个波束报告资源,所述波束报告资源对应于一个或多个所述第一发射接收点,所述分别向多个第一发射接收点发送对应的第一波束报告,包括:在所述波束报告资源上,发送所述波束报告资源对应的第一发射接收点的第一波束报告,为实现在保证收发性能的基础上节约波束报告的开销,设计了合理的信令配置。
如图3所示,本发明的一个实施例提供一种传输波束报告的方法300,该方法可以由移动终端执行,换言之,该方法可以由安装在移动终端的软件或硬件来执行,该方法包括如下步骤:
S302:在多个第一发射接收点对应于多个波束报告配置的情况下,根据所述多个波束报告配置,对多个第一发射接收点对应的多个第一波束报告进行整合以生成基于组的波束报告,通过单个空域滤波器或多个并行空域滤波器,同时发送或接收所述基于组的波束报告中包含的多个参考信号。
在本步骤中,当进行波束管理时,波束质量计算能够考虑多个TRP,由此保证收发性能。UE可以同时发送或接收所述多个波束报告配置中包含的RS。在随后的步骤中,UE在进行基于组的波束报告(groupBasedBeamReporting)上报时,将能够同时接收或发送的RS,拆分到多个第一波束报告中,在相应的波束报告资源中分别发送给对应的TRP。由此节约波束报告的开销。
在本步骤中可以基于锚点,对多个第一发射接收点对应的多个第一波束 报告进行整合以生成基于组的波束报告,其中,所述锚点为所述波束报告资源中的至少一个资源。即一个完整的groupBasedBeamReporting,从锚点开始统计,直到下次锚点出现前。因为当多个第一发射接收点对应了多个第一波束报告时,存在这些波束报告或波束报告配置中包含的RS的时域周期不同、频域资源或空域资源冲突等问题,还有这些波束报告配置以谁为主的问题,为了解决这些问题,需要一个锚点来确定一个完整的groupBasedBeamReporting的开始和结束。例如,多个波束报告配置中,以不同的波束报告配置为主、或以不同的波束报告配置为groupBasedBeamReporting的开始,很可能得到不同的groupBasedBeamReporting,即groupBasedBeamReporting包含的RS、RS的波束质量均可能不同,该分歧就需要锚点来解决。
在一种实现方式中,若多个波束报告配置(report setting)的周期不同,则完整的groupBasedBeamReporting中,每个report setting只采用最新的波束报告,将旧的波束报告替换掉。
在一种实现方式中,所述锚点由所述第一发射接收点的标识决定。
其中,所述第一发射接收点的标识包括:标识为0的发射接收点(TRP ID=0)、标识最大的发射接收点(highest TRP ID)、标识最小的发射接收点(lowest TRP ID)、标识为0的控制资源集(CORESET 0)关联的发射接收点、标识最大的控制资源集(highest CORESET ID)关联的发射接收点、标识最小的控制资源集(lowest CORESET ID)关联的发射接收点、网络指示的发射接收点和用户设备上报的发射接收点中的至少一者。其中,TRP ID为CORESET中的控制资源集池索引CORESETPoolIndex,或TRP对应点物理小区ID,或其它表征TRP的ID。
在一种实现方式中,所述锚点由网络指示或移动终端上报的资源或配置决定。
在一种实现方式中,所述锚点由所述波束报告资源或波束报告配置决定。
其中,所述波束报告资源或波束报告配置包括:最先或最后配置的资源或配置、所述波束报告资源或波束报告配置中的频域资源、所述波束报告资源或波束报告配置中的时域资源、所述波束报告资源或波束报告配置中空间相关信息或传输配置指示或传输配置指示中的参考信号中的至少一者。
可选地,所述波束报告资源或波束报告配置中的频域资源包括:所述波束报告资源或波束报告配置中最低的频域资源,所述波束报告资源或波束报告配置中最高的频域资源,所述波束报告资源或波束报告配置中资源最多的频域资源,例如资源单元(Resource element,RE)最多的频域资源,和所述波束报告资源或波束报告配置中资源最少的频域资源中的至少一者。
可选地,所述波束报告资源或波束报告配置中的时域资源包括:所述波束报告资源或波束报告配置中最远时刻的时域资源,所述波束报告资源或波束报告配置中最近时刻的时域资源,所述波束报告资源或波束报告配置中资源最多的时域资源,例如,正交频分复用(Orthogonal frequency division multiplexOFDM)符号、符号(symbol)、时隙(slot)等最多,和所述波束报告资源或波束报告配置中资源最少的时域资源中的至少一者。
可选地,所述波束报告资源或波束报告配置中空间相关信息或传输配置指示中的参考信号包括:CORESET的准共址(Quasi-colocation,QCL)的RS,其中,CORESET例如,CORESET ID=0的CORESET,最低CORESET ID的CORESET,最高CORESET ID的CORESET;最近时刻激活的TCI或该TCI中的RS,最近时刻使用的TCI或该TCI中的RS,最近时刻配置的TCI或该TCI中的RS;之前的波束报告中波束质量最好的RS;RS的频域资源,例如,最低、最高、资源最多或资源最少的频域资源;和RS的时域资源,例如,最远时刻的时域资源,最近时刻的时域资源,资源最多的时域资源,资源最少的时域资源;RS ID最大;RS ID最小;SSB优先;或CSI-RS优先中的至少一者。
在一种实现方式中,所述第一波束报告和/或所述基于组的波束报告中的 报告量为cri-SINR或cri-参考信号接收功率(RSRP)或ssb-Index-SINR或ssb-Index-RSRP或sri-SINR或sri-RSRP时,所述报告量的测量基于所述基于组的波束报告中的参考信号。
在一种实现方式中,在所述基于组的波束报告中波束测量时参考的参考信号为:与所述波束报告资源最近时刻的参考信号、所述基于组的波束报告开始前的最近时刻的参考信号、和所述基于组的波束报告内的参考信号中的至少一种。其中,与所述波束报告资源最近时刻的参考信号,即某个波束报告资源计算时,以当前时刻为参考,选取最近时刻的RS和其它波束报告或配置的RS。
在一种实现方式中,关于SINR的计算,所述第一波束报告和/或所述基于组的波束报告中一个参考信号对应多个信噪比。
考虑不同的TRP同时传输或发送的组合,例如:
对于两个TRP或UE配置两个天线面板(Panel)的场景,则一个RS最多可以上报2个SINR,即另一个TRP或panel传输或不传输。
对于N个TRP或UE配置N个Panel的场景,一个RS最多可以上报2的(N-1)次方个SINR,其中N大于1。例如,当N=3时,记另外两个TRP或Panel为A和B,由于2的(3-1)次方等于4,则此时存在4种情况,即A传输B传输、A传输B不传输、A不传输B传输、A不传输B不传输。
若TRP数目和UE配置的Panel数目不等,则基于TRP数目、Panel数目、TRP数目和Panel数目的较小值或较大值中的至少一者确定一个RS最多可以上报SINR的个数。由此,本发明的一个实施例提供一种传输波束报告的方法,为上报SINR提供了合理有效的解决方案。
UE处理信道状态信息(Channel State Information,CSI)报告的能力,即支持的同时计算CSI的数量N CPU,需要报告给网络。如果一个UE支持N CPU个同时CSI的计算意味着UE有N CPU个CSI处理单元(CSI processing unit,CPU)用于处理所有配置小区的CSI报告。
可用的CPU数量:在某个OFDM符号,如果已经有L个CPU被占用处理CSI报告,则UE还有N CPU-L个可用CPU。如果在该OFDM符号有N个CSI报告要开始占用CPU,第n=0,…,N-1个CSI报告需要占用
Figure PCTCN2021087209-appb-000001
个CPU,有可能可用的CPU数量少于N个CSI报告需要占用的CPU数量,则UE不需要更新N-M个低优先级的CSI报告,其中0≤M≤N是满足
Figure PCTCN2021087209-appb-000002
Figure PCTCN2021087209-appb-000003
的最大值。
在一种实现方式中,所述对多个第一发射接收点对应的多个第一波束报告进行整合以生成基于组的波束报告的步骤对应的CPU占用时间为以下占用时间中的至少一种:
占用时间1:在周期或半持续CSI且报告量不为空的情况下,占用CPU的起始符号为所述基于组的波束报告之前的最近一次信道或干扰测量的CSI-RS或CSI-干扰测量(CSI-IM)或SSB传输的各CSI-RS或CSI-IM或SSB资源中的最早符号,和/或,终止符号为传输所述基于组的波束报告的最后一个上行信道的最后符号。
占用时间2:在非周期CSI和由物理下行控制信道(Physical downlink control channel,PDCCH)激活的基于物理上行共享信道(Physical Uplink Shared Channel,PUSCH)的半持续CSI报告的首次传输,且报告量不为空的情况下,占用CPU的起始符号为所述基于组的波束报告触发的第一个CSI报告的PDCCH之后的第一个符号,和/或,终止符号为传输所述基于组的波束报告的最后一个PUSCH的最后符号。
占用时间3:起始符号为最近一个所述基于组的波束报告中用于L1-RSRP计算的信道测量的周期或半持续(P/SP)CSI-RS/SSB资源传输的最早符号,和/或,终止符号为最近一个所述基于组的波束报告中用于L1-RSRP计算的信道测量的CSI-RS/SSB资源传输的最后符号之后的Z′ 3个符号。
占用时间4:在非周期且报告量为空且未配置trs-Infor的情况下,占用CPU的起始符号为所述基于组的波束报告触发的第一个CSI报告的PDCCH 之后的第一个符号,和/或,终止符号为下列符号1-3任意一种或多种符号中的最后一个符号:
符号1:所述基于组的波束报告的触发第一个CSI报告的PDCCH之后的第一个符号之后的Z 3个符号。
符号2:所述基于组的波束报告的触发最后一个CSI报告的PDCCH之后的第一个符号之后的Z 3个符号。
符号3:最近一次用于所述基于组的波束报告的L1-RSRP计算的信道测量的CSI-RS/SSB资源传输的最后符号之后的Z′ 3个符号。
其中,在一种实现方式中,由PDCCH激活的基于PUSCH的半持续CSI(Semi-Persistent CSI,SP-CSI)报告的首次传输不适用于占用时间1;在一种实现方式中,由PDCCH激活的基于PUSCH的半持续CSI报告的首次传输适用于占用时间2;在一种实现方式中,由PDCCH激活的基于PUSCH的半持续CSI报告的首次传输不适用于占用时间3。
由此,本发明的一个实施例提供一种传输波束报告的方法,为CPU的衡量提供了合理有效的解决方案。
