在一些实施例中,对于Type I-MP-CB(Type I-Multiple Panels-Codebook,类型一多面板码本),可以支持的面板数Ng=2或Ng=4,每个面板关联一个CSI-RS资源,则CSI-RS资源个数K=Ng=2或K=Ng=4。当总的端口数PCSI-RS=48时,K=2且每个资源有24个端口;当PCSI-RS=64时,K=2且每个资源有32个端口,或K=4且每个资源有16个端口;当PCSI-RS=128时,K=4且每个资源有32个端口。Type I-MP-CB可Rank=1-4传输。
示例的,Type I-MP-CB的结构为:
其中,W1为:多面板中每个面板对应的SD向量(Space Domain-vector,空域向量)独立选择,其选择方式与Rel-15Type I码本模式1且PCSI-RS<16,Rank=1-4的SD向量选择方式相同。W2为:面板之间的共相位因子其中i=2,…,Ng,独立选择和宽带上报,且所有层对应的面板之间共相位因子相同;每个面板内的极化间共相位因子设计方式与Rel-15Type I单面板码本采用的共相位因子设计方式相同,且每个面板对应的极化间共相位因子相互独立。
在一些实施例中,基于Rel-15Type I SP CB模式1且PCSI-RS<16的单面板码本,指示所选的SD向量的开销为:其中,分别指示水平维SD向量和垂直维SD向量。若采用对于Rel-15Type I SP CB模式1指示所选的SD向量,当Ng=4时,总的SD向量反馈开销为
在一些实施例中,当面板数较大且总的天线端口数较少时,例如,Ng=4,PCSI-RS=64,每个天线面板对应的端口仅为16,发送天线波束变宽,使得UE(User Equipment,用户设备)选择的多个面板对应的SD向量可能存在相同。若终端所选的SD向量相同时,则只需要上报一个SD向量指示信息用于指示所选的SD向量即可,以避免相同SD向量的重复指示,从而减少CSI反馈开销。
图2A是根据本公开实施例示出的通信方法的交互示意图。如图2A所示,本公开实施例涉及通信方法,上述方法包括:
步骤S2101,网络设备102向终端101发送码本参数信息。
在一些实施例中,终端101接收码本参数信息。
在一些实施例中,码本参数信息用于指示终端所选面板码本对应的码本参数。
在一些实施例中,码本参数信息包括以下至少一项:Ng,N1,N2,O1,O2
示例的,其中Ng为网络设备所选当前多面板码本下支持的面板数量,N1为Ng个面板中单个面板对应水平维天线端口数,N2为Ng个面板中单个面板对应垂直维天线端口数,O1为当前多面本码本下的第一过采样因子,O2为当前多面板码本下的第二过采样因子。终端可以基于网络设备发送的码本参数信息确定如何上报所选的SD向量,以及上报该SD向量对应的比特开销。
在一些实施例中,码本参数信息的名称不做限定,其例如是“参数信息”、“码本数据信息”、“码本参考信息”等。
步骤S2102,终端101向网络设备102发送第一信息。
在一些实施例中,网络设备102接收第一信息。
在一些实施例中,第一信息用于指示Ng个第一面板中,N′g个第二面板对应的第一空域向量是否 相同,Ng为正整数,N′g为小于或等于Ng的正整数。
示例的,终端在进行SD向量指示时,先确定需要指示的SD向量中是否存在相同的SD向量,并向网络设备发送第一信息,该第一信息用于指示网络设备指示的Ng个第一面板中,N′g个第二面板对应的第一空域向量是否相同。其中,Ng为正整数,N′g为小于或等于Ng的正整数。例如,终端基于上述码本参数信息确定网络设备支持的面板数为4,终端触发SD向量上报时,确定该4个面板码本中存在2个面板码本的SD向量相同,则终端先向网络设备发送第一信息,该第一信息指示2个面板码本中的SD向量相同。
在一些实施例中,第一信息中包括面板码本的码本编号,示例的,当终端确定存在面板码本的SD向量相同时,通过第一信息指示存在N′g个面板码本中的SD向量相同,通过码本编号指示SD向量相同对应N′g个面板码本的码本编号。
在一些实施例中,第一信息的名称不做限定,其例如是“指示信息”、“SD向量重复信息”、“SD向量异同信息”等。
在一些实施例中,第一信息通过CSI的第一部分承载。
示例的,本实施例中第一信息包含在CSIPart 1中。通过CSIPart 1向网络设备指示终端所选N′g个面板码本中的SD向量是否相同。
在一些实施例中,该方法还包括:
根据Ng,确定第一信息的比特数。
示例的,本实施例中为避免SD向量的重复指示,并较少SD向量指示过程中的信号开销。基于Ng来确定第一信息传输过程中所需要消耗的比特数。示例的,可以在终端中设定Ng与第一信息开销比特数之间的映射关系,基于该映射关系确定当前Ng下,传输第一信息所需要消耗的比特数。例如,当Ng=2时,终端上报第一信息所消耗的比特数A=1bit;当Ng=4,终端上报第一信息所消耗的比特数A=4bit。
步骤S2103,终端101确定N′g个第二面板对应的第一空域向量相同,向网络设备102发送第二信息。
在一些实施例中,网络设备102接收第二信息。
在一些实施例中,第二信息用于指示终端所选N′g个第二面板对应的第一空域向量。
示例的,该第一空域向量为终端当前所选需要上报的N′g个第二面板对应的相同的一个空域向量。也即终端当前在N′g个第二面板中选择的需要上报的空域向量均相同。
在一些实施例中,第二信息的名称不做限定,其例如是“SD向量指示信息”、“相同SD向量指示信息”、“多面板对应一个空域向量的指示信息”。
在一些实施例中,第二信息的比特数为其中,N1为水平维天线端口数,N2为垂直维天线端口数,O1为第一过采样因子,O2为第二过采样因子。
示例的,本实施例中为减少SD向量上报过程中的指示开销,需要规定SD向量指示信息的信号开销。当确定终端所选N′g个面板中上报的SD向量相同时,传输第二信息所消耗的比特数为其中,N1为终端所选面板码本对应水平维天线端口数,N2为终端所选面板码本对应垂直维天线端口数,O1为第一过采样因子,O2为第二过采样因子。
示例的,若当前网络设备指示的码本参数信息中Ng=2,每个码本面本对应的CSI-RS(Channel State Information-Reference Signal,信道状态信息参考信号)资源端口数为32,且每个面板对应的水平维天线端口数和垂直维天线端口数均为4,也即N1=N2=4,则过采样因子O1=O2=4。若UE基于估计的下行信道信息选择出N′g=2个面板对应相同的SD向量,则UE上报A=1bit指示信息,指示该N′g个面板所选的SD向量相同,并向网络设备指示该相同的SD向量,其中SD向量的指示信息大小为对应的指示SD向量的总开销为9bits。若采用相关技术中的指示方式SD向量的指示总开销为:因此基于本实施例的SD向量指示方式相较于相关技术中的指示方式减少了7bits的传输开销。在避免相同SD向量重复指示的同时,减少SD向量的指示开销,保证系统性能。
在一些实施例中,第二信息通过CSI的第二部分承载。
示例的,本实施例中CSIPart 2中包括第二信息,终端通过CSIPart 2向网络设备指示N′g个面板对应的相同SD向量。
步骤S2104,终端101向网络设备102发送第三信息。
在一些实施例中,网络设备102接收第三信息。
在一些实施例中,第三信息用于指示Ng-N′g个第三面板对应的第二空域向量。
示例的,第一信息指示N′g个面板所选的SD向量相同,在终端101还需要指示其他面板中的第二空域向量时,需要通过第三信息对Ng-N′g个第三面板中的不同SD向量。
在一些实施例中,第三信息的比特数为其中,N1为水平维天线端口数,N2为垂直维天线端口数,O1为第一过采样因子,O2为第二过采样因子。
示例的,对于Ng-N′g个第三面板中的不同SD向量的指示信息开销,本实施例中采用确定存在其他不同SD向量的指示上报时,该第二空域向量对应指示信息的开销。
示例的,当UE在Ng个面板中所选的N′g个第二面板对应的SD向量相同,那么对于N′g个第二面板的SD向量上报,UE只上报一个SD向量的指示信息和第一信息,其中,第一信息用于指示N′g个第二面板对应的SD向量相同,SD向量的指示信息用于指示该相同的SD向量。此时,该指示信息的大小为然后UE分别上报剩下Ng-N′g个面板对应的SD向量指示信息,该指示信息的大小为则终端用于指示所选面板中对应的SD向量的总开销为:

示例的,当UE在Ng个面板中所选的N′g个第二面板对应的SD向量相同,那么对于N′g个第二面板的SD向量上报,UE只上报一个SD向量的指示信息和第一信息,其中,第一信息用于指示N′g个第二面板对应的SD向量相同,SD向量的指示信息用于指示该相同的SD向量。此时,该指示信息的大小为然后UE分别上报剩下Ng-N′g个面板对应的SD向量指示信息,该指示信息的大小为则终端用于指示所选面板中对应的SD向量的总开销为:
