Description
本发明涉及通信领域。
为了缓解日趋紧张的频谱资源,新无线(New Radio,NR)引入了高频通信方式,以便增加通信系统可用的频率资源,进而提升系统容量。
应该注意,上面对技术背景的介绍只是为了方便对本发明的技术方案进行清楚、完整的说明,并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本发明的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
在frequency range 2(FR2),由于硬件的限制,在同一个正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)符号上,用户设备(User Equipment,UE)只能保证根据同一个准共址类型D参数(QCL type-D参数)的监听下行控制信道。
因此,现有的标准中规定了以下行为:
当信道状态信息参考信号(Channel State Information-Reference Signal,CSI-RS)与一个控制资源集(control-resource set,CORESET)关联的搜索空间(search space,SS)在相同的OFDM符号,并且,该CSI-RS与高层参数重复设置为“on”的一个NZP-CSI-RS-ResourceSet不关联时,UE认为(assume)该CSI-RS与在该CORESET内发送的物理下行控制信道解调参考信号(PDCCH DM-RS)是关于QCL-TypeD参数准共址(QCL)的,也就是说,UE在CSI-RS和CORESET发生时域重叠的情况下,根据该CORESET关联的QCL-typeD参数接收该CSI-RS。
例如,图1是现有的某个时隙slot n的一示意图。如图1所示,在时隙slot n中,UE在交叉线区域监听PDCCH candidate。该区域对应Search space#1(SS#1),并且SS#1与CORESET#1关联。在这个例子中,CORESET#1的激活TCI状态为TCI#1,TCI#1包括QCL-typeD参数QCL-typeD#1。CSI-RS在第二个符号发送。
由于发送CSI-RS的符号与交叉线区域有相同的OFDM符号,并且CORESET的优先级高于CSI-RS,因此,UE根据CORESET#1所对应的QCL-typeD参数(QCL-typeD#1)接收CSI-RS。
发明人发现,在某些场景中,例如,在高速火车-单频网(High speed train single frequency network,HST-SFN)场景中,终端设备一般置于高速列车中,而网络设备通常固定在铁轨两侧。当火车高速移动时(例如,高达330公里每小时),由于多普勒效应,终端设备与网络设备之间的通信质量会受到严重的影响,尤其是下行控制信道的可靠性会急剧下降。为了降低这方面的影响,一种解决方案是终端设备同时接收来自多个发送和接收点(Transmit-Receive Point,TRP)的相同的下行控制信道。为了能够从空间上区分出不同TRP,一个用于接收下行控制信道的CORESET需要与两个不同的空间方向关联,也就是说,一个CORESET会与两个不同QCL-typeD参数关联。
当待接收的CSI-RS与一个CORESET关联的搜索空间在相同的OFDM符号,并且该CORESET与两个不同的QCL-typeD参数关联时,目前没有方法能够确定用于接收该CSI-RS的空间方向。
本申请实施例提供一种无线通信的装置及方法,根据第一CSI-RS所关联的空间接收参数与CORESET所关联的不同的两个空间接收参数的关系,确定接收该第一CSI-RS使用的空间接收参数,这样,在该CORESET与不同的两个空间接收参数关联时,能够确定用于接收该第一CSI-RS的空间方向。

实施例1
本申请实施例提供一种无线通信的方法,应用于终端设备侧。图3是本申请实施例1的无线通信的方法的一示意图。如图3所示,该方法包括:
步骤301:根据第一信道状态信息参考信号(CSI-RS)所关联的空间接收参数与控制资源集(CORESET)所关联的不同的两个空间接收参数的关系,确定接收该第一信道状态信息参考信号使用的空间接收参数,其中,该第一信道状态信息参考信号 与该控制资源集关联的搜索空间集在时域上重叠;以及
步骤302:根据确定的该空间接收参数,接收该第一信道状态信息参考信号。
这样,在该CORESET与不同的两个空间接收参数关联时,能够确定用于接收该第一CSI-RS的空间方向。
在本申请实施例中,第一信道状态信息参考信号即第一CSI-RS是指待接收的CRI-RS。
在本申请实施例中,例如,第一CRI-RS是用于时频追踪的CSI-RS(CSI-RS for tracking)、用于波束管理的CSI-RS(CSI-RS for beam management)或者用于信道状态信息测量(CSI measurement)的CSI-RS。更具体地说,例如:
用于时频追踪的CSI-RS是指一个在CSI-RS集合中的CSI-RS资源,其中,该CSI-RS集合配置了高层参数“trs-info”(a CSI-RS resource in a NZP-CSI-RS-ResourceSet configured with higher layer parameter trs-Info)。
用于波束管理的CSI-RS是指一个在CSI-RS集合中的CSI-RS资源,其中,该CSI-RS集合配置了高层参数“重复”(a CSI-RS resource in a NZP-CSI-RS-ResourceSet configured with higher layer parameter repetition)。
用于信道状态信息测量的CSI-RS是指一个在CSI-RS集合中的CSI-RS资源,其中,该CSI-RS集合既没有配置高层参数“重复”也没有配置高层参数“trs-info”(a CSI-RS resource in a NZP-CSI-RS-ResourceSet configured without higher layer parameter trs-Info and without higher layer parameter repetition)。
在本申请实施例中,例如,第一CRI-RS是一个在CSI-RS集合中的CSI-RS资源,其中,该CSI-RS集合没有把高层参数“重复”配置为“开”(a CSI-RS resource associated with a NZP-CSI-RS-ResourceSet with the higher layer parameter other than repetition set to'on')。
在本申请实施例中,空间接收参数(Spatial Rx parameter)是终端设备用于接收信号的与空间相关的参数,例如,空间接收参数是QCL-TypeD参数。在本申请实施例中,以QCL-TypeD参数为例进行说明。
在本申请实施例中,例如,QCL-TypeD参数可以是一个信道状态信息参考信号,本申请实施例中称为第二信道状态信息参考信号,即第二CRI-RS;或者,QCL-TypeD参数可以是一个同步信号块(Synchronization Signal Block,SSB)。
在本申请实施例中,第一CSI-RS所关联的空间接收参数可以是一个,也可以是两个。
在本申请实施例中,控制资源集(CORESET)与不同的两个空间接收参数关联,这两个空间接收参数可以是不同的第二CRI-RS,或者,不同的SSB,或者,一个是第二CRI-RS,另一个是SSB。
在本申请实施例中,第一CSI-RS所关联的空间接收参数以及CORESET所关联的不同的两个空间接收参数可以是网络配置的。
在本申请实施例中,第一CRI-RS以及CORESET可以通过传输配置指示(transmission configuration indicator,TCI)状态而与空间接收参数关联。
例如,该CORESET被激活了两个TCI状态,分别为TCI#1和TCI#2,第一CRI-RS与TCI#3关联,而TCI#1所关联的用于指示QCL-typeD property的参考信号为CSI-RS#1,TCI#2所关联的用于指示QCL-typeD property的参考信号为CSI-RS#2,TCI#3所关联的用于指示QCL-typeD property的参考信号为CSI-RS#3,那么,第一CRI-RS所关联的空间接收参数为CSI-RS#3,该CORESET所关联的两个空间接收参数为CSI-RS#1和CSI-RS#2。
在本申请实施例中,该第一CSI-RS与该CORESET关联的搜索空间集在时域上重叠,例如,该第一CSI-RS与该CORESET位于相同的OFDM符号。
在本申请实施例中,该第一CSI-RS与该CORESET可以在相同的或不同的带内载波分量(intra-band component carriers)上。
在步骤301中,终端设备根据第一CSI-RS所关联的空间接收参数与CORESET所关联的不同的两个空间接收参数的关系,确定接收该第一CSI-RS使用的空间接收参数。以下,对具体的确定方法进行说明。
首先,考虑第一CSI-RS所关联的空间接收参数是一个空间接收参数的情况。
例如,当该第一CSI-RS所关联的一个空间接收参数与该CORESET所关联的两个空间接收参数均不同时,终端设备将该CORESET所关联的两个空间接收参数中的一个空间接收参数确定为接收该第一CSI-RS使用的空间接收参数。
在本申请实施例中,需要判断两个空间接收参数是否相同,例如,分别判断该第一CSI-RS所关联的一个空间接收参数与该CORESET所关联的两个空间接收参数是否相同。
例如,当一个空间接收参数为CSI-RS,另一个空间接收参数为SSB时,则认为这两个空间接收参数不同。
例如,当一个空间接收参数为一个CSI-RS,另一个空间接收参数为另一个CSI-RS时,并且这两个CSI-RS所关联的同步信号块不同时,则认为这两个空间接收参数不同。
在本申请实施例中,如上所述,当该第一CSI-RS所关联的一个空间接收参数与该CORESET所关联的两个空间接收参数均不同时,终端设备可以将该CORESET所关联的两个空间接收参数中的一个空间接收参数确定为接收该第一CSI-RS使用的空间接收参数,
例如,该CORESET所关联的两个空间接收参数中的一个空间接收参数是,根据该两个空间接收参数所关联的SSB的确定的。例如,该第一CSI-RS所关联的空间接收参数为一个SSB;该CORESET所关联的两个空间接收参数中的一个空间接收参数是,该CORESET所关联的两个空间接收参数中与该SSB关联的空间接收参数。
在步骤302中,根据确定的该空间接收参数,接收该第一CSI-RS。,
在本申请实施例中,接收该第一CSI-RS也可以称为检测该第一CSI-RS。具体的检测或接收方法可以参考相关技术。
下面举例进行说明。
图4是本发明实施例1的某个时隙slot n的一示意图。如图4所示,SS#1(搜索空间集合,search space set)与CORESET#1关联,CORESET#1与两个TCI状态TCI#1、TCI#2关联,或者说CORESET#1被激活了两个TCI状态(TCI#1,TCI#2)。如图4所示,该CSI-RS用于时频追踪,它与TCI#3关联。
另外,TCI#1所关联的用于指示QCL-typeD property的参考信号为CSI-RS#1,CSI-RS#1与SSB#1相关;TCI#2所关联的用于指示QCL-typeD property的参考信号为CSI-RS#2,CSI-RS#2与SSB#2相关;TCI#3所关联的用于指示QCL-typeD property的参考信号为SSB#1。
因此,CORESET#1所关联的QCL-typeD参数为CSI-RS#1和CSI-RS#2,该CSI-RS所关联的QCL-typeD参数为SSB#1。
虽然CSI-RS与CORESET#1都与SSB#1关联,但是CSI-RS与SSB的测量精度不同,UE不一定有能力同时接收它们。也就是说,UE不能根据为该CSI-RS配置的 QCL-typeD参数检测或接收该CSI-RS。这时,UE应当根据CORESET#1所对应的QCL-typeD参数检测或接收该CSI-RS。具体地说,由于CSI-RS对应的QCL-typeD参数为SSB#1,并且CSI-RS#1与SSB#1相关联,这时UE根据CSI-RS#1,即QCL-typeD#1检测或接收该CSI-RS。
这样,由于CSI-RS所配置的TCI状态所关联的SSB和接收该CSI-RS所关联的SSB是一致的,能够保证UE使用与其配置的空间方向相近的空间方向接收CSI-RS,保证CSI-RS的测量精度,有利于提升系统性能。
又例如,该CORESET所关联的两个空间接收参数中的一个空间接收参数是,根据该两个空间接收参数所关联的TCI状态确定的。例如,该CORESET所关联的两个空间接收参数中的一个空间接收参数是,该两个空间接收参数所关联的TCI状态的索引最小的空间接收参数。
下面举例进行说明。
图5是本发明实施例1的某个时隙slot n的另一示意图。如图5所示,SS#1与CORESET#1关联。CORESET#1与两个TCI状态TCI#1、TCI#2关联,或者说CORESET#1被激活了两个TCI状态(TCI#1,TCI#2)。如图5所示,该CSI-RS用于时频追踪,它与TCI#3关联。
另外,TCI#1所关联的用于指示QCL-typeD property的参考信号为CSI-RS#1,CSI-RS#1与SSB#1相关;TCI#2所关联的用于指示QCL-typeD property的参考信号为CSI-RS#2,CSI-RS#2与SSB#2相关;TCI#3所关联的用于指示QCL-typeD property的参考信号为SSB#1。
因此,CORESET#1所关联的QCL-typeD参数为CSI-RS#1和CSI-RS#2,CSI-RS所关联的QCL-typeD参数为SSB#3。
由于CSI-RS与CORESET#1对应不同的QCL-typeD参数,UE没有能力同时接收它们。也就是说,UE不能根据为该CSI-RS配置的QCL-typeD参数检测或接收该CSI-RS。这时,UE应当根据CORESET#1所对应的QCL-typeD参数检测或接收该CSI-RS。具体地说,UE根据与CORESET#1关联的索引(index)最小的TCI状态(TCI#1)所关联的QCL-typeD参数(QCL-typeD#1)检测或接收该CSI-RS。
这样,在NR系统中,索引较小的TCI状态一般用于确定default beam,更为重要。CSI-RS根据索引较小的TCI状态进行检测或接收,能够使其对更重要的空间方 向进行检测,有利于提升系统性能。
图6是本发明实施例1的某个时隙slot n的又一示意图。如图6所示,SS#1与CORESET#1关联。CORESET#1与两个TCI状态TCI#1、TCI#2关联,或者说CORESET#1被激活了两个TCI状态(TCI#1,TCI#2)。如图6所示,CSI-RS与TCI#3关联。
另外,TCI#1所关联的用于指示QCL-typeD property的参考信号为CSI-RS#1,CSI-RS#1与SSB#1相关;TCI#2所关联的用于指示QCL-typeD property的参考信号为CSI-RS#2,CSI-RS#2与SSB#2相关;TCI#3所关联的用于指示QCL-typeD property的参考信号为CSI-RS#3,CSI-RS#3与SSB#3相关。
因此,CORESET#1所关联的QCL-typeD参数为CSI-RS#1和CSI-RS#2,CSI-RS所关联的QCL-typeD参数为SSB#3。
由于CSI-RS与CORESET#1对应不同的QCL-typeD参数,UE没有能力同时接收它们。也就是说,UE不能根据为该CSI-RS配置的QCL-typeD参数检测或接收该CSI-RS。这时,UE应当根据CORESET#1所对应的QCL-typeD参数检测或接收该CSI-RS。具体地说,UE根据与CORESET#1关联的index最低的TCI状态(TCI#1)所对应的QCL-typeD参数(QCL-typeD#1)检测或接收该CSI-RS。
这样,在NR系统中,索引较小的TCI状态一般用于确定default beam,更为重要。CSI-RS根据索引较小的TCI状态进行检测或接收,能够使其对更重要的空间方向进行检测,有利于提升系统性能。
又例如,该CORESET所关联的两个空间接收参数中的一个空间接收参数是,根据该两个空间接收参数所关联的第二CSI-RS的索引确定的。例如,该CORESET所关联的两个空间接收参数中的一个空间接收参数是,该两个空间接收参数所关联的第二CSI-RS的索引最小的空间接收参数。例如,如图5和图6所示,UE根据与CORESET#1关联的索引(index)最小的CSI-RS(CSI-RS#1)所关联的QCL-typeD参数(QCL-typeD#1)检测或接收该CSI-RS。
这样,在NR系统中,索引较小的CSI-RS一般更为重要。根据索引较小的CSI-RS进行检测或接收,能够使其对更重要的空间方向进行检测,有利于提升系统性能。
以上说明的是当该第一CSI-RS所关联的一个空间接收参数与该CORESET所关联的两个空间接收参数均不同时,终端设备将该CORESET所关联的两个空间接收参 数中的一个空间接收参数确定为接收该第一CSI-RS使用的空间接收参数;也可以是,当该第一CSI-RS所关联的一个空间接收参数与该CORESET所关联的两个空间接收参数均不同时,终端设备将该CORESET所关联的两个空间接收参数确定为接收该第一CSI-RS使用的空间接收参数。
例如,该第一CSI-RS与两个空间接收参数关联,该两个空间接收参数中的一个空间接收参数与该CORESET所关联的两个空间接收参数均不同时,终端设备将该CORESET所关联的两个空间接收参数确定为接收该第一CSI-RS使用的空间接收参数。
图7是本发明实施例1的某个时隙slot n的又一示意图。如图7所示,SS#1与CORESET#1关联。CORESET#1与两个TCI状态(TCI#1、TCI#2)关联,或者说CORESET#1被激活了两个TCI状态(TCI#1,TCI#2)。如图7所示,CSI-RS与TCI#3、TCI#4关联。
另外,TCI#1所关联的用于指示QCL-typeD property的参考信号为CSI-RS#1,CSI-RS#1与SSB#1相关;TCI#2所关联的用于指示QCL-typeD property的参考信号为CSI-RS#2,CSI-RS#2与SSB#2相关;TCI#3所关联的用于指示QCL-typeD property的参考信号为CSI-RS#3,CSI-RS#3与SSB#1相关;TCI#4所关联的用于指示QCL-typeD property的参考信号为CSI-RS#4,CSI-RS#4与SSB#4相关。
因此,CORESET#1所关联的QCL-typeD参数为CSI-RS#1和CSI-RS#2,CSI-RS所关联的QCL-typeD参数为CSI-RS#3和CSI-RS#4。
由于CSI-RS与CORESET#1对应的QCL-typeD参数有一部分不完全相同,UE没有能力同时接收它们。也就是说,UE不能根据为该CSI-RS配置的QCL-typeD参数检测或接收该CSI-RS。这时,UE应当根据CORESET#1所关联的QCL-typeD参数检测或接收该CSI-RS。具体地说,由于CSI-RS配置了两个不同的QCL-typeD参数,UE根据CORESET#1所关联的两个QCL-typeD参数(QCL-typeD#1和QCL-typeD#2)检测或接收该CSI-RS。
这样,当CSI-RS与CORESET在时域重叠时,由于用于接收CSI-RS的QCL-typeD参数与CORESET相同,该CSI-RS可以用于测量CORESET的信道状态。另外,这种方法可以利用CSI-RS的配置信息区分CSI-RS的测量对象(也就是当CSI-RS所配置的TCI状态仅关联一个QCL-typeD参数时,该CSI-RS用于测量CORESET所关联 的一个QCL-typeD参数;当CSI-RS所配置的TCI状态关联两个QCL-typeD参数时,该CSI-RS与该CORESET共享相同的QCL-typeD),以便基站进行合理调整,保证测量精度,进而提升系统性能。
以上,针对该第一CSI-RS所关联的空间接收参数与该CORESET所关联的两个空间接收参数不同的情况进行了说明。下面,针对该第一CSI-RS所关联的空间接收参数与该CORESET所关联的两个空间接收参数相同的情况进行说明。
在步骤301中,例如,当该第一CSI-RS所关联的一个空间接收参数与该CORESET所关联的两个空间接收参数中的一个空间接收参数相同时,将该CSI-RS所关联的该空间接收参数确定为接收该第一CSI-RS使用的空间接收参数;和/或,当该第一CSI-RS所关联的两个空间接收参数与该CORESET所关联的两个空间接收参数分别相同时,将该CSI-RS所关联的该两个空间接收参数确定为接收该第一CSI-RS使用的空间接收参数。
在本申请实施例中,该CSI-RS所关联的一个空间接收参数与该CORESET所关联的两个空间接收参数中的一个空间接收参数相同,包括:
作为该第一CSI-RS所关联的一个空间接收参数的一个第二CSI-RS与作为该CORESET所关联的两个空间接收参数中的一个空间接收参数的一个第二CSI-RS相同;和/或,
该第一CSI-RS所关联的一个空间接收参数所关联的一个同步信号块(SSB)与该CORESET所关联的两个空间接收参数中的一个空间接收参数所关联的一个同步信号块相同。
以下进行示例性的说明。
图8是本发明实施例1的某个时隙slot n的又一示意图。如图8所示,SS#1与CORESET#1关联。CORESET#1与两个TCI状态TCI#、TCI#2关联,或者说CORESET#1被激活了两个TCI状态(TCI#1,TCI#2)。CSI-RS与TCI#3关联。
另外,TCI#1所关联的用于指示QCL-typeD property的参考信号为CSI-RS#1;TCI#2所关联的用于指示QCL-typeD property的参考信号为CSI-RS#2;TCI#3所关联的用于指示QCL-typeD property的参考信号为CSI-RS#1。
因此,CORESET#1所关联的QCL-typeD参数为CSI-RS#1和CSI-RS#2,CSI-RS所关联的QCL-typeD参数为CSI-RS#1。
由于CSI-RS所关联的QCL-typeD参数与CORESET#1所关联的其中一个QCL-typeD参数相同,因此,UE有能力接收该CSI-RS,也就是说,UE根据为该CSI-RS配置的QCL-typeD参数检测或接收该CSI-RS。
这样,在特定条件下,也就是当CSI-RS的一个QCL-typeD参数与CORESET的其中一个QCL-typeD参数相同时,UE能够根据为该CSI-RS系统配置的QCL-typeD参数接收该CSI-RS,避免行为模糊,能够保证CSI-RS的测量精度,有利于提升系统性能。
在本申请实施例中,该第一CSI-RS所关联的两个空间接收参数与该CORESET所关联的两个空间接收参数分别相同,包括:作为该第一CSI-RS所关联的两个空间接收参数的两个第二CSI-RS与作为该CORESET所关联的两个空间接收参数的两个第二CSI-RS分别相同;和/或,该第一CSI-RS所关联的两个空间接收参数所分别关联的两个同步信号块(SSB)与该CORESET所关联的两个空间接收参数所分别关联的两个同步信号块相同。
以下进行示例性的说明。
图9是本发明实施例1的某个时隙slot n的又一示意图。如图9所示,SS#1与CORESET#1关联。CORESET#1与两个TCI状态TCI#、TCI#2关联,或者说CORESET#1被激活了两个TCI状态(TCI#1,TCI#2)。CSI-RS与TCI#3、TCI#4关联。
另外,TCI#1所关联的用于指示QCL-typeD property的参考信号为CSI-RS#1;TCI#2所关联的用于指示QCL-typeD property的参考信号为CSI-RS#2;TCI#3所关联的用于指示QCL-typeD property的参考信号为CSI-RS#1;TCI#4所关联的用于指示QCL-typeD property的参考信号为CSI-RS#2
因此,CORESET#1所关联的QCL-typeD参数为CSI-RS#1和CSI-RS#2,CSI-RS所关联的QCL-typeD参数为CSI-RS#1和CSI-RS#2。
由于CSI-RS所关联的QCL-typeD参数与CORESET#1所关联的QCL-typeD参数相同,因此,UE有能力接收该CSI-RS,也就是说,UE根据为该CSI-RS配置的QCL-typeD参数检测或接收该CSI-RS。
这样,在特定条件下,也就是当CSI-RS的两个QCL-typeD参数与CORESET的两个QCL-typeD参数分别相同时,UE能够根据为该CSI-RS系统配置的QCL-typeD 参数接收该CSI-RS,避免行为模糊,能够保证CSI-RS的测量精度,有利于提升系统性能。
图10是本发明实施例1的某个时隙slot n的又一示意图。如图10所示,SS#1与CORESET#1关联。CORESET#1与两个TCI状态TCI#1、TCI#2关联,或者说CORESET#1被激活了两个TCI状态(TCI#1,TCI#2)。CSI-RS与TCI#3、TCI#4关联。
另外,TCI#1所关联的用于指示QCL-typeD property的参考信号为CSI-RS#1;其中CSI-RS#1与SSB#1相关;TCI#2所关联的用于指示QCL-typeD property的参考信号为CSI-RS#2;其中CSI-RS#2与SSB#2相关;TCI#3所关联的用于指示QCL-typeD property的参考信号为CSI-RS#1;其中CSI-RS#3与SSB#1相关;TCI#4所关联的用于指示QCL-typeD property的参考信号为CSI-RS#2;其中CSI-RS#4与SSB#2相关。
因此,CORESET#1所关联的QCL-typeD参数为CSI-RS#1和CSI-RS#2,CSI-RS所关联的QCL-typeD参数为CSI-RS#3和CSI-RS#4。
虽然CSI-RS所关联的QCL-typeD参数与CORESET#1所关联的QCL-typeD参数不相同,但是这些QCL-typeD参数所关联的SSB是相同的。因此,UE有能力接收该CSI-RS,也就是说,UE根据为该CSI-RS配置的QCL-typeD参数检测或接收该CSI-RS。
这样,在特定条件下,也就是当CSI-RS所关联的SSB与CORESET所关联的两个SSB分别相同时,UE能够根据为该CSI-RS系统配置的QCL-typeD参数接收该CSI-RS,避免行为模糊,能够保证CSI-RS的测量精度,有利于提升系统性能。
在本申请实施例中,在配置了面板(panel)信息的情况下,还可以结合面板信息来确定接收第一CSI-RS的空间接收参数。
图11是本申请实施例1的无线通信的方法的另一示意图。如图11所示,该方法包括:
步骤1101:根据第一CSI-RS所关联的空间接收参数以及该第一CSI-RS所关联的天线面板(panel)信息与CORESET所关联的两个空间接收参数以及该CORESET所关联的天线面板信息的关系,确定接收该第一CSI-RS使用的空间接收参数;以及
步骤1102:根据确定的该空间接收参数,接收该第一CSI-RS。
对于第一CSI-RS所关联的空间接收参数与该CORESET所关联的两个空间接收 参数中的一个空间接收参数不同的情况,例如,当一个空间接收参数关联的天线面板信息与另一个空间接收参数所关联的天线面板信息不同时,则认为这两个空间接收参数不同。
该CORESET所关联的两个空间接收参数中的一个空间接收参数是,根据该两个空间接收参数所关联的第二CSI-RS的天线面板信息确定的。
例如,该第一CSI-RS与一个天线面板信息关联;该CORESET所关联的两个空间接收参数中的一个空间接收参数是,该CORESET所关联的两个空间接收参数中与该天线面板信息关联的空间接收参数。
对于第一CSI-RS所关联的空间接收参数与该CORESET所关联的两个空间接收参数中的一个空间接收参数相同的情况,例如,在步骤1101中,当该第一CSI-RS所关联的一个空间接收参数与该CORESET所关联的两个空间接收参数中的一个空间接收参数相同,且该第一CSI-RS所关联的一个天线面板信息与该CORESET所关联的两个空间接收参数中的一个所关联的天线面板信息相同时,将该CSI-RS所关联的该空间接收参数确定为接收该第一CSI-RS使用的空间接收参数;和/或,当该第一CSI-RS所关联的两个空间接收参数与该CORESET所关联的两个空间接收参数分别相同,且该第一CSI-RS所关联的两个天线面板信息与该CORESET所关联的两个天线面板信息分别相同时,将该CSI-RS所关联的该两个空间接收参数确定为接收该第一CSI-RS使用的空间接收参数。
以下针对结合面板信息确定接收该第一CSI-RS使用的空间接收参数的情况进行示例性的说明。
图12是本发明实施例1的某个时隙slot n的又一示意图。如图12所示,SS#1与CORESET#1关联,CORESET#1与两个TCI状态TCI#1、TCI#2关联,或者说CORESET#1被激活了两个TCI状态(TCI#1,TCI#2)。如图4所示,该CSI-RS用于时频追踪,它与TCI#3关联。
另外,TCI#1所关联的用于指示QCL-typeD property的参考信号为CSI-RS#1,CSI-RS#1与SSB#1相关;TCI#2所关联的用于指示QCL-typeD property的参考信号为CSI-RS#2,CSI-RS#2与SSB#2相关;TCI#3所关联的用于指示QCL-typeD property的参考信号为SSB#1。TCI#1与panel#1关联;TCI#2与panel#2关联;TCI#3与panel#1关联。
因此,CORESET#1所关联的QCL-typeD参数为CSI-RS#1和CSI-RS#2,CSI-RS所关联的QCL-typeD参数为SSB#1。
虽然CSI-RS与CORESET#1都与SSB#1关联并且对应的panel信息相同,但是CSI-RS与SSB的测量精度不同,UE不一定有能力同时接收它们。也就是说,UE不能根据为该CSI-RS配置的QCL-typeD参数检测或接收该CSI-RS。这时,UE应当根据CORESET#1所关联的QCL-typeD参数检测或接收该CSI-RS。具体地说,由于CSI-RS#1与SSB#1相关,并且panel ID相同,UE根据CSI-RS#1(QCL-typeD#1)检测或接收该CSI-RS。
这样,由于CSI-RS所配置的TCI状态所关联的天线面板信息和接收该CSI-RS所关联的天线面板信息是一致的,能够保证UE使用与其配置的空间方向相近的空间方向接收CSI-RS,保证CSI-RS的测量精度,有利于提升系统性能。
图13是本发明实施例1的某个时隙slot n的又一示意图。如图13所示,SS#1与CORESET#1关联。CORESET#1与两个TCI状态TCI#1、TCI#2关联,或者说CORESET#1被激活了两个TCI状态(TCI#1,TCI#2)。如图5所示,该CSI-RS用于时频追踪,它与TCI#3关联。
另外,TCI#1所关联的用于指示QCL-typeD property的参考信号为CSI-RS#1,CSI-RS#1与SSB#1相关;TCI#2所关联的用于指示QCL-typeD property的参考信号为CSI-RS#2,CSI-RS#2与SSB#2相关;TCI#3所关联的用于指示QCL-typeD property的参考信号为SSB#1。TCI#1与panel#1关联;TCI#2与panel#2关联;TCI#3与panel#1关联。
因此,CORESET#1所关联的QCL-typeD参数为CSI-RS#1和CSI-RS#2,CSI-RS所关联的QCL-typeD参数为SSB#1。
由于CSI-RS与CORESET#1对应不同的QCL-typeD参数,UE没有能力同时接收它们。也就是说,UE不能根据为该CSI-RS配置的QCL-typeD参数检测或接收该CSI-RS。这时,UE应当根据CORESET#1所关联的QCL-typeD参数检测或接收该CSI-RS。具体地说,由于CSI-RS对应panel#1,UE根据与Panel#1关联的TCI状态所关联的QCL-typeD参数(QCL-typeD#1)检测或接收该CSI-RS。
这样,由于CSI-RS所配置的TCI状态所关联的天线面板信息和接收该CSI-RS所关联的天线面板信息是一致的,能够保证UE使用与其配置的空间方向相近的空间 方向接收CSI-RS,保证CSI-RS的测量精度,有利于提升系统性能。
图14是本发明实施例1的某个时隙slot n的又一示意图。如图14所示,SS#1与CORESET#1关联。CORESET#1与两个TCI状态TCI#1、TCI#2关联,或者说CORESET#1被激活了两个TCI状态(TCI#1,TCI#2)。如图6所示,CSI-RS与TCI#3关联。
另外,TCI#1所关联的用于指示QCL-typeD property的参考信号为CSI-RS#1,CSI-RS#1与SSB#1相关;TCI#2所关联的用于指示QCL-typeD property的参考信号为CSI-RS#2,CSI-RS#2与SSB#2相关;TCI#3所关联的用于指示QCL-typeD property的参考信号为CSI-RS#3,CSI-RS#3与SSB#3相关。TCI#1与panel#1关联;TCI#2与panel#2关联;TCI#3与panel#1关联。
因此,CORESET#1所关联的QCL-typeD参数为CSI-RS#1和CSI-RS#2,CSI-RS所关联的QCL-typeD参数为SSB#1。
由于CSI-RS与CORESET#1对应不同的QCL-typeD参数,UE没有能力同时接收它们。也就是说,UE不能根据为该CSI-RS配置的QCL-typeD参数检测或接收该CSI-RS。这时,UE应当根据CORESET#1所关联的QCL-typeD参数检测或接收该CSI-RS。具体地说,由于CSI-RS对应panel#1,UE根据与Panel#1关联的TCI state所关联的QCL-typeD参数(QCL-typeD#1)检测或接收该CSI-RS。
这样,由于CSI-RS所配置的TCI状态所关联的天线面板信息和接收该CSI-RS所关联的天线面板信息是一致的,能够保证UE使用与其配置的空间方向相近的空间方向接收CSI-RS,保证CSI-RS的测量精度,有利于提升系统性能。
图15是本发明实施例1的某个时隙slot n的又一示意图。如图15所示,SS#1与CORESET#1关联。CORESET#1与两个TCI状态(TCI#1、TCI#2)关联,或者说CORESET#1被激活了两个TCI状态(TCI#1,TCI#2)。CSI-RS与TCI#3、TCI#4关联。
另外,TCI#1所关联的用于指示QCL-typeD property的参考信号为CSI-RS#1,CSI-RS#1与SSB#1相关;TCI#2所关联的用于指示QCL-typeD property的参考信号为CSI-RS#2,CSI-RS#2与SSB#2相关;TCI#3所关联的用于指示QCL-typeD property的参考信号为CSI-RS#3,CSI-RS#3与SSB#1相关;TCI#4所关联的用于指示QCL-typeD property的参考信号为CSI-RS#4,CSI-RS#4与SSB#4相关。TCI#1与 panel#1关联;TCI#2与panel#2关联;TCI#3与panel#1关联;TCI#4与panel#2关联。
因此,CORESET#1所关联的QCL-typeD参数为CSI-RS#1和CSI-RS#2,CSI-RS所关联的QCL-typeD参数为SSB#1。
由于CSI-RS与CORESET#1对应不同的QCL-typeD参数,UE没有能力同时接收它们。也就是说,UE不能根据为该CSI-RS配置的QCL-typeD参数检测或接收该CSI-RS。这时,UE应当根据CORESET#1所关联的QCL-typeD参数检测或接收该CSI-RS。具体地说,由于CSI-RS配置了两个不同的QCL-typeD参数并且它们对应不同的panel,UE根据CORESET#1所关联的QCL-typeD参数(QCL-typeD#1和QCL-typeD#2)检测或接收该CSI-RS。
这样,当CSI-RS与CORESET在时域重叠时,由于用于接收CSI-RS的天线面板信息与CORESET的天线面板信息相同,该CSI-RS可以用于测量CORESET的信道状态。另外,这种方法可以利用CSI-RS的配置信息区分CSI-RS的测量对象(也就是当CSI-RS所配置的TCI状态仅关联一个天线面板信息时,该CSI-RS用于测量CORESET所关联的一个天线面板信息;当CSI-RS所配置的TCI状态关联两个天线面板信息时,该CSI-RS与该CORESET共享相同的天线面板信息),以便基站进行合理调整,保证测量精度,进而提升系统性能。
图16是本发明实施例1的某个时隙slot n的又一示意图。如图16所示,SS#1与CORESET#1关联。CORESET#1与两个TCI状态TCI#、TCI#2关联,或者说CORESET#1被激活了两个TCI状态(TCI#1,TCI#2)。CSI-RS与TCI#3关联。
另外,TCI#1所关联的用于指示QCL-typeD property的参考信号为CSI-RS#1;TCI#2所关联的用于指示QCL-typeD property的参考信号为CSI-RS#2;TCI#3所关联的用于指示QCL-typeD property的参考信号为CSI-RS#1。TCI#1与panel#1关联;TCI#2与panel#2关联;TCI#3与panel#1关联。
因此,CORESET#1所关联的QCL-typeD参数为CSI-RS#1和CSI-RS#2,CSI-RS所关联的QCL-typeD参数为CSI-RS#1。
由于CSI-RS所关联的QCL-typeD参数与CORESET#1所关联的其中一个QCL-typeD参数相同,并且相应地它们的panel ID也相同,因此,UE有能力接收该CSI-RS,也就是说,UE根据为该CSI-RS配置的QCL-typeD参数检测或接收该CSI-RS。
这样,在特定条件下,也就是当CSI-RS的两个QCL-typeD参数与CORESET的两个QCL-typeD参数分别相同,并且它们对应的天线面板信息也相同时,UE能够根据为该CSI-RS系统配置的QCL-typeD参数接收该CSI-RS,避免行为模糊,保证CSI-RS的测量精度,有利于提升系统性能。

另外,TCI#1所关联的用于指示QCL-typeD property的参考信号为CSI-RS#1;TCI#2所关联的用于指示QCL-typeD property的参考信号为CSI-RS#2;TCI#3所关联的用于指示QCL-typeD property的参考信号为CSI-RS#1;TCI#4所关联的用于指示QCL-typeD property的参考信号为CSI-RS#2。TCI#1与panel#1关联;TCI#2与panel#2关联;TCI#3与panel#1关联;TCI#4与panel#2关联。
这里,CORESET#1所关联的QCL-typeD参数为CSI-RS#1和CSI-RS#2,CSI-RS所关联的QCL-typeD参数为CSI-RS#1和CSI-RS#2。
由于CSI-RS所关联的QCL-typeD参数与CORESET#1所关联的QCL-typeD参数相同,并且相应地它们的panel ID也相同,因此,UE有能力接收该CSI-RS,也就是说,UE根据为该CSI-RS配置的QCL-typeD参数检测或接收该CSI-RS。
这样,在特定条件下,也就是当CSI-RS的两个QCL-typeD参数与CORESET的两个QCL-typeD参数分别相同,并且它们的天线面板信息也相同时,UE能够根据为该CSI-RS系统配置的QCL-typeD参数接收该CSI-RS,避免行为模糊,能够保证CSI-RS的测量精度,有利于提升系统性能。
图18是本发明实施例1的某个时隙slot n的又一示意图。如图18所示,SS#1与CORESET#1关联。CORESET#1与两个TCI状态TCI#1、TCI#2关联,或者说CORESET#1被激活了两个TCI状态(TCI#1,TCI#2)。CSI-RS与TCI#3、TCI#4关联。
另外,TCI#1所关联的用于指示QCL-typeD property的参考信号为CSI-RS#1;其中CSI-RS#1与SSB#1相关;TCI#2所关联的用于指示QCL-typeD property的参考信号为CSI-RS#2;其中CSI-RS#2与SSB#2相关;TCI#3所关联的用于指示QCL-typeD property的参考信号为CSI-RS#1;其中CSI-RS#3与SSB#1相关;TCI#4所关联的用于指示QCL-typeD property的参考信号为CSI-RS#2;其中CSI-RS#4与SSB#2相关。TCI#1与panel#1关联;TCI#2与panel#2关联;TCI#3与panel#1关联;TCI#4与panel#2关联。
因此,CORESET#1所关联的QCL-typeD参数为CSI-RS#1和CSI-RS#2,CSI-RS所关联的QCL-typeD参数为CSI-RS#1和CSI-RS#2。
虽然CSI-RS所关联的QCL-typeD参数与CORESET#1所关联的QCL-typeD参数不相同,但是这些QCL-typeD参数所关联的SSB是相同的,并且相应地它们的panel ID也相同,因此,UE有能力接收该CSI-RS,也就是说,UE根据为该CSI-RS配置的QCL-typeD参数检测或接收该CSI-RS。
这样,在特定条件下,也就是当CSI-RS所关联的SSB与CORESET所关联的两个SSB分别相同,并且它们的天线面板信息也相同时,UE能够根据为该CSI-RS系统配置的QCL-typeD参数接收该CSI-RS,避免行为模糊,能够保证CSI-RS的测量精度,有利于提升系统性能。
在本申请实施例中,该天线面板信息可以包括以下信息中的至少一个:显式地指示的面板标识(panel ID);天线端口分组信息;天线面板分组信息;以及与信道状态信息报告(CSI report)相关的信息。
由上述实施例可知,终端设备根据第一CSI-RS所关联的空间接收参数与CORESET所关联的不同的两个空间接收参数的关系,确定接收该第一CSI-RS使用的空间接收参数,这样,在该CORESET与不同的两个空间接收参数关联时,能够确定用于接收该第一CSI-RS的空间方向。
