Description

传输信道状态信息-参考信号CSI-RS的方法及装置 技术领域
本发明实施例涉及通信技术,尤其涉及一种传输信道状态信息-参考信号(Channel State Information-Reference Signal,简称CSI-RS)的方法及装置。
背景技术
随着用户终端数量的不断增加,而目前长期演进系统(Long Term Evolution Advanced,简称LTE)Release12中基站仅仅支持最多8个CSI-RS端口,这种情况造成LTE系统的吞吐量比较低,因此增加基站的CSI-RS端口个数是提高系统吞吐量的有效手段。
对于LTE Release12中,基站支持8个CSI-RS端口的情况,通常在一个物理资源块(Physical Resource Block,简称PRB)对中存在五种配置模式,每种配置模式为8个CSI-RS端口与资源元素(Resource Element,简称RE)的一种对应关系,其中端口与REs之间具有相应的对应关系,更多的CSI-RS端口与有限的资源元素(Resource Element,简称RE)如何对应是亟待解决的问题。
现有技术中,通过下面的方式来解决CSI-RS端口与RE的对应问题,若目前端口数增加到12个,12个端口序号从0-11,在一个子帧中端口0-7仍然采用8个端口的五种配置模式,在另一个子帧中端口8-11则采用8个端口中前4个端口所对应的RE进行CSI-RS信号的传输。
然而,现有技术增加的端口只能在另一个子帧中发送CSI-RS信号,导致用户终端不能及时接收到CSI-RS信号,进而造成信道估计效率较低的问题;并且信道的时间域变化较大时,对信道估计的性能也造成较大的影响,进而影响系统性能。

针对当前LTE演进系统三维多入多出(Full-Dimension Multiple Input Multiple Output,简称FD-MIMO),需要扩展基站的端口;由于如果继续扩大CSI-RS端口占用的RE,同时无法改变其他参考信号占用RE的情况,会导致用于发送数据的TE数目减少,反而会降低系统的吞吐量,因此,基站基于扩展的端口所采用的配置模式占用的RE和基于8个端口所采用的配置模式所占用的RE保持一致,不再继续扩大占用RE的数目。下面以12个CSI-RS端口和16个CSI-RS端口分别为例进行说明:
一种情况,第一配置模式包括12个CSI-RS端口,则基站基于一个PRB对确定CSI-RS的第一配置模式,包括:所述基站按照端口号的顺序确定所述第一配置模式的前8个CSI-RS端口占用任一种所述第二配置模式所占用的全部RE,所述第一配置模式的后4个CSI-RS端口占用其他一种或其他多种所述第二配置模式所占用的部分RE。
图3A为本发明一实施例提供的基于12个CSI-RS端口在一个PRB对中的配置模式一,如图3A所示,一、基于12个CSI-RS端口的第一配置模式 可以是:第二配置模式0中的8个端口0-7所占用的RE,现在均由12个端口中的前8个端口占用,后4个端口使用第二配置模式1所占用的RE,新的端口8、9、10、11分别对应原8个端口中的2、3、6、7;二、基于12个CSI-RS端口的第一配置模式可以是:第二配置模式3中的8个端口0-7所占用的RE,现在均由12个端口中的前8个端口占用,后4个端口使用第二配置模式4所占用的RE,新的端口8、9、10、11分别对应原8个端口中的0、1、4、5;三、基于12个CSI-RS端口的第一配置模式可以是:第二配置模式2中的8个端口0-7所占用的RE,现在均由12个端口中的前8个端口占用,后4个端口使用第二配置模式4所占用的RE,新的端口8、9、10、11分别对应原8个端口中的0、1、4、5。因此,在图3A中目前包括有三种基于12个CSI-RS端口的第一配置模式。

图3C为本发明一实施例提供的基于12个CSI-RS端口在一个PRB对中的配置模式三,如图3C所示,一、基于12个CSI-RS端口的第一配置模式可以是:第二配置模式0中的8个端口0-7所占用的RE,现在均由12个端口中的前8个端口占用,后4个端口使用第二配置模式1所占用的RE,新的端口8、9、10、11分别对应原8个端口中的2、3、6、7;二、基于12个CSI-RS端口的第一配置模式可以是:第二配置模式2中的8个端口0-7所占用的RE, 现在均由12个端口中的前8个端口占用,后4个端口使用第二配置模式4所占用的RE,新的端口8、9、10、11分别对应原8个端口中的0、1、4、5;三、基于12个CSI-RS端口的第一配置模式可以是:第二配置模式3中的8个端口0-7所占用的RE,现在均由12个端口中的前8个端口占用,后4个端口使用第二配置模式4所占用的RE,新的端口8、9、10、11分别对应原8个端口中的2、3、6、7。因此,在图3C中目前包括有三种基于12个CSI-RS端口的第一配置模式。
图3D为本发明一实施例提供的基于12个CSI-RS端口在一个PRB对中的配置模式四,如图3D所示,一、基于12个CSI-RS端口的第一配置模式可以是:第二配置模式0中的8个端口0-7所占用的RE,现在均由12个端口中的前8个端口占用,后4个端口使用第二配置模式1所占用的RE,新的端口8、9、10、11分别对应原8个端口中的2、3、6、7;二、基于12个CSI-RS端口的第一配置模式可以是:第二配置模式2中的8个端口0-7所占用的RE,现在均由12个端口中的前8个端口占用,后4个端口使用第二配置模式4所占用的RE,新的端口8、9、10、11分别对应原8个端口中的2、3、6、7;三、基于12个CSI-RS端口的第一配置模式可以是:第二配置模式1中的8个端口0-7所占用的RE,现在均由12个端口中的前8个端口占用,后4个端口使用第二配置模式4所占用的RE,新的端口8、9、10、11分别对应原8个端口中的0、1、4、5。因此,在图3D中目前包括有三种基于12个CSI-RS端口的第一配置模式。
另一种情况,所述第一配置模式包括16个CSI-RS端口;则所述基站基于一个PRB对,确定CSI-RS的第一配置模式,包括:所述基站按照端口号的顺序确定所述第一配置模式的前8个CSI-RS端口占用任一种所述第二配置模式所占用的全部RE,所述第一配置模式的后8个CSI-RS端口占用另一种所述第二配置模式所占用的全部RE;或者所述第一配置模式的后8个CSI-RS端口占用其他多种所述第二配置模式所占用的部分资源元素RE。

图4B为本发明一实施例提供的基于16个CSI-RS端口在一个PRB对中的配置模式二,如图4B所示,一、基于16个CSI-RS端口的第一配置模式可以是:第二配置模式0中的8个端口0-7所占用的RE,现在均由12个端口中的前8个端口占用,后8个端口使用第二配置模式1所占用的RE;二、基于16个CSI-RS端口的第一配置模式可以是:第二配置模式3中的8个端口0-7所占用的RE,现在均由12个端口中的前8个端口占用,后8个端口使用第二配置模式4所占用的RE。因此,在图3A中目前包括有三种基于12个CSI-RS端口的第一配置模式。剩下的RE可以对应的端口8-15。
可选地,第一配置模式包括12或16个CSI-RS端口;则所述基站基于一个PRB对确定CSI-RS的第一配置模式,包括:
基站确定时域或者频域方向上多个PRB对中所述第二配置模式未被聚合的部分RE或者全部RE,并建立所述未被聚合的部分RE或者全部RE与第一配置模式的CSI-RS端口的对应关系。
进一步地,基站确定时域或者频域方向上所述多个PRB对中的所述第一配置模式的总数目。
比如:结合图3A-图3C,基站确定三个PRB对中第二配置模式未被聚合的RE,图3A中

对应的RE未被聚合,图4B中
Figure PCTCN2015091211-appb-000007
