Description

一种信息传输方法、装置及设备 技术领域
本发明涉及无线通信技术领域,尤其涉及一种信息传输方法、装置及设备。
背景技术
在宽带码分多址(Wideband Code Division Multiple Access,WCDMA)系统中,为了提高用户设备(User Equipment,UE)的数据传输速率,以及增强边缘UE接收信号的信干燥比,小区可以为UE配置下行多输入多输出(Multiple Input Multiple Output,MIMO)传输方式。
当UE处于服务小区的时候,如果服务小区发射MIMO信号,UE需要知道小区采用的预编码信息(PCI,Pre-Coding Information),才能正确解调出MIMO信号。
当UE处于服务小区和邻小区的边界时,会收到来自邻小区的干扰信号。为了提高对服务小区的信号的接收质量,UE可以对邻小区进行干扰处理,处理的方式包括干扰消除、干扰抑制等。对于MIMO干扰信号,UE需要知道MIMO干扰信号所使用的PCI,以便进行干扰消除或者干扰抑制操作。如果UE不知道MIMO干扰信号所使用的PCI,则无法对MIMO干扰信号进行正确的建模,进行干扰消除或者干扰抑制的效果会很差。
小区在发送用于进行信道估计的导频信号时,需要基于虚拟天线映射(Virtual Antenna Mapping,VAM)矩阵对导频信号进行预编码。如图1所示,假设主导频信号为P0,辅导频信号为P1,数据流1信号为x1,数据流2信号为x2,VAM矩阵为S,用于对数据流信号进行预编码的矩阵为B,B为已知的预编码矩阵组中的任意一个矩阵,信道矩阵为H,则图2中的主导频信号P0、辅导频信号P1在UE侧的接收信号y1、y2可以表示为:
Figure PCTCN2015088326-appb-000001
可见,基于已知的接收信号y1,y2,和已知的发送导频信号P0、P1,UE可以得出HS。
图2中的数据流信号x1、x2在UE侧的接收信号z1、z2可以表示为:
Figure PCTCN2015088326-appb-000002
Figure PCTCN2015088326-appb-000003
上式(2)对应两个发送数据流信号,(3)对应一个发送数据流信号。可见,UE若要正确解调出x1、x2,需要知道H,而UE通过接收的导频信号,只能估计出HS,显然,UE将无法进行数据信号的正确解调。
如图2所示,为另外一种MIMO发射方式,在这种发射方式下,导频信号的发射采用上述式(1)的发射方式,对于数据信号,分别采用S-1B和基于导频信号能够估计出的HS进行预编码,如下式:
Figure PCTCN2015088326-appb-000004
Figure PCTCN2015088326-appb-000005
上式(4)对应两个发送数据流信号,(5)对应一个发送数据流信号。可见,UE若要正确解调出x1、x2,不仅需要基于导频信号估计出HS,还需要知道S-1B,UE在不知道S-1B的情况下无法进行数据信号的正确解调。
综上,在WCDMA的MIMO传输方式下,UE无法进行数据信号的正确解调,从而导致无法正确接收服务小区的信号,并无法对邻小区信号进行有效的干扰消除或者干扰抑制。

如图8所示,为本发明一实施例提供的信息传输方法流程图,包括以下步骤:
S801:网络侧设备确定发送MIMO信号的至少一个小区的VAM矩阵信息。
这里的至少一个小区可以包括UE的服务小区和/或邻小区。
这里的网络侧设备可以是RNC,或基站。
基于MIMO发射方式的不同,这里的VAM矩阵信息可以有两种体现形式:一种是直接指示小区所采用的VAM矩阵的信息;另一种是指示小区所采用的预编码码本组的信息,该预编码码本组为基于VAM矩阵和能够使用的预编码矩阵集合生成的码本集合,用于对MIMO信号进行解调。以下实施例二中将会对VAM矩阵信息的指示作具体说明,这里不再详述。
S802:网络侧设备将所述至少一个小区的VAM矩阵信息通知给UE。
这里,当网络侧设备为RNC时,RNC可以通过无线资源控制(Radio  Resource Control,RRC)信令,将所述至少一个小区的VAM矩阵信息通知给UE。当网络侧设备为基站时,该基站通过物理层信令将VAM矩阵信息通知给UE,该物理层信令包括广播信令或专用控制信令。
S803:针对任一小区,所述UE基于该小区的VAM矩阵信息,对接收的该小区的MIMO信号进行解调。
这里,若VAM矩阵信息中指示了具体的VAM矩阵,UE可以基于该VAM矩阵估计出信道矩阵,基于估计出的信道矩阵进行数据信号解调。若VAM矩阵信息中指示了预编码码本组,则可以基于该预编码码本组进行数据信号解调。详见下述实施例二的描述。
下面,以网络侧设备为RNC为例,介绍下本发明实施例的具体实施过程。
如图9所示,为本发明另一实施例提供的信息传输方法流程图,包括以下步骤:
S901:RNC确定发送MIMO信号的至少一个小区的VAM矩阵信息。
这里,RNC确定发送MIMO信号的至少一个小区的VAM矩阵信息可以包括以下两种情况中的一种或两种:
情况一:RNC确定管理的至少一个基站(NodeB)下的小区的VAM矩阵信息。
在这种情况下,RNC可以确定管理的部分或全部基站下的小区的VAM矩阵信息。另外,RNC可以确定管理的至少一个基站中每个基站下的一个或多个小区(至少一个小区)的VAM矩阵信息。
在具体实施中,RNC可以有两种方式确定管理的至少一个基站下的小区的VAM矩阵信息,分别为:
方式一:RNC接收所述至少一个基站分别发送的小区的VAM矩阵信息;
在这种方式下,由基站配置覆盖的小区的VAM矩阵信息,并通知给RNC。
方式二:RNC为管理的所述至少一个基站下的小区分别配置所述VAM矩阵信息。
在这种方式下,RNC为管理的部分或全部基站中,每个基站下的至少一 个小区分别配置所述VAM矩阵信息。
在具体实施中,RNC为小区配置VAM矩阵信息后,将该小区的VAM矩阵信息通知给该小区所属的基站,从而小区可以获取到该VAM矩阵信息,使用该VAM矩阵信息与UE之间进行MIMO传输。
情况二:RNC确定其它RNC管理的至少一个基站下的小区的VAM矩阵信息。
在具体实施中,RNC可以通过与其它RNC进行交互,接收其它RNC发送的该其它RNC管理的基站下的小区的VAM矩阵信息。
S902:所述RNC通过RRC信令,将所述至少一个小区的VAM矩阵信息通知给UE。
该步骤中,RNC通过RRC信令,将确定的至少一个小区的VAM矩阵信息通知给UE,以便UE使用VAM矩阵信息对接收的MIMO信号进行解调。
S903:针对任一小区,所述UE基于该小区的VAM矩阵信息,对接收的该小区的多输入多输出MIMO信号进行解调。
在具体实施中,针对服务小区的VAM矩阵信息,UE可以使用该VAM矩阵信息对接收的服务小区的MIMO信号进行解调。针对邻小区的VAM矩阵信息,UE可以使用该VAM矩阵信息对邻小区的MIMO信号进行解调,以便实现邻小区干扰消除或者干扰抑制。
基于进行MIMO发射方式的不同,上述S901~S903中的VAM矩阵信息可以有两种体现方式:
一、直接指示小区所采用的VAM矩阵的信息;
小区的VAM矩阵信息可以包括以下信息中的一种或多种:
用于指示VAM矩阵的标识信息;
用于指示VAM矩阵所采用的相位的标识信息;
该小区的标识信息。
在上述信息中,小区的标识信息用于区分不同的VAM矩阵所对应的小区;
VAM矩阵的标识信息具体可以是VAM矩阵的序号等能区分不同VAM矩阵的标识信息,比如,可以预先定义N个VAM矩阵{S1,S2,…Sn,…,SN},只需要向UE通知VAM矩阵的序号n,UE即可获知具体的VAM矩阵;
用于指示VAM矩阵所采用的相位的标识信息可以是指VAM矩阵所采用的相位的序号等区分不同相位的标识信息。具体说明如下:
对于2×2MIMO(即两发两收)传输形式,VAM矩阵可表示为:
Figure PCTCN2015088326-appb-000006
可见,VAM矩阵S可以由第一相位
Figure PCTCN2015088326-appb-000007
和第二相位θ来确定。
在具体实施中,可以定义N个相位组合
Figure PCTCN2015088326-appb-000008
RNC将选中的相位组合的序号n通知给UE,UE即可确定Sn;还可以定义K个第一相位序号
Figure PCTCN2015088326-appb-000009
J个第二相位序号{θ12,...,θj...,θJ},RNC将选中的第一相位序号k和第二相位序号j通知给UE,UE即可确定
Figure PCTCN2015088326-appb-000010
基于上述VAM矩阵信息进行MIMO信号解调的说明:
假设主导频信号为P0,辅导频信号为P1,数据流1信号为x1,数据流2信号为x2,VAM矩阵为S,用于对数据流信号进行预编码的矩阵为B,B为已知的预编码矩阵组中的任意一个矩阵,信道矩阵为H,则发送的主导频信号P0、辅导频信号P1对应的UE侧的接收信号y1、y2可以表示为:
Figure PCTCN2015088326-appb-000011
可见,基于已知的接收信号y1,y2,和已知的发送导频信号P0、P1,UE得出HS,通过本发明实施例介绍的上述方案,UE可以获知VAM矩阵S,从而可以解出信道矩阵H。
数据流x1、x2在UE侧的接收信号z1、z2可以表示为:
Figure PCTCN2015088326-appb-000012
Figure PCTCN2015088326-appb-000013
上式(2)对应两个发送数据流信号,(3)对应一个发送数据流信号。可见,UE基于解出的信道矩阵H,以及已知的预编码矩阵组中的任意一个矩阵B,可以正确解调出接收信号z1、z2。
二、指示小区所采用的预编码码本组的信息,该预编码码本组为基于VAM矩阵和能够使用的预编码矩阵集合生成的码本集合,用于对MIMO信号进行解调。
VAM矩阵信息可以包括以下信息中的一种或多种:
所述预编码码本组的标识信息;
用于生成所述预编码码本组的VAM矩阵的信息;
该小区的标识信息。
在该方式下,导频信号仍采用上述式(1)的发射方式,对于数据信号,分别采用S-1B和基于导频信号能够估计出的HS进行预编码,如下式:
Figure PCTCN2015088326-appb-000014
Figure PCTCN2015088326-appb-000015
上式(4)对应两个发送数据流信号,(5)对应一个发送数据流信号。可见,UE可以基于导频信号估计出HS,通过本发明实施例介绍的上述方案,UE可以获知VAM矩阵S,从而可以得到S-1B,基于S-1B和HS,UE可以对接收的数据信号进行正确地建模,从而解调出接收的数据信号。
上式中,S-1B即为所述预编码码本组;在具体实施中,RNC可以通知UE发射MIMO信号的小区使用的预编码码本组S-1B,每个预编码码本组由1个S-1和一组B相乘得到。
在具体实施中,可以预先定义N个预编码码本组:{S1 -1B,S2 -1B,…,Sn -1B…,SN -1B},RNC只需要向UE通知预编码码本组的序号n,UE即可获 知具体的Sn -1B。另外,由于预编码码本组中的B是一个固定的矩阵组中的矩阵,因此RNC可以仅向UE通知VAM矩阵S的信息,这时,通知VAM矩阵的信息可以包括上述介绍的VAM矩阵的标识信息,或VAM矩阵所采用的相位的标识信息等。
以下实施例三和实施例四分别以网络侧设备为服务小区和邻小区为例进行介绍,具体实施与实施例二重复之处,比如VAM矩阵信息的体现形式及利用方式,将不再赘述。
如图10所示,为本发明又一实施例提供的信息传输方法流程图,包括以下步骤:
S1001:基站确定发送MIMO信号的至少一个小区的VAM矩阵信息;
这里,所述至少一个小区包括UE的服务小区和/或至少一个邻小区。
可选地,若所述基站为服务基站,则所述至少一个小区可以包括所述UE的服务小区和邻小区;若所述基站为邻基站,则所述至少一个小区可以包括所述邻基站覆盖的至少一个小区。
也即,服务基站除可以向UE发送该UE的服务小区的VAM矩阵信息外,还可以向UE发送该UE的至少一个邻小区的VAM矩阵信息,这里的至少一个邻小区可以是该服务基站覆盖下的小区,也可以是邻基站覆盖下的小区;另外,服务基站具体可以通过UE的服务小区向UE发送所述至少一个小区的VAM矩阵信息。
邻基站可以只向UE发送该邻基站覆盖的至少一个小区的VAM矩阵信息。当然,邻基站也可以向UE发送该邻基站获取的其它基站下的小区的VAM矩阵信息。具体地,该邻基站可以通过覆盖下的一个或多个小区(UE的邻小区)向该UE发送至少一个小区的VAM矩阵信息。
在具体实施中,基站可以获取RNC配置的所述至少一个小区的VAM矩阵信息;在这种方式下,RNC配置管理的至少一个基站下的小区的VAM矩阵信息,还可以接收其它RNC发送的该其它RNC配置的小区的VAM矩阵信息,RNC将自己配置的和/或其它RNC发送的VAM矩阵信息发送给管理的至 少一个基站。
或者,基站为自身覆盖的至少一个小区配置VAM矩阵信息,并获取其它基站配置的至少一个小区的VAM矩阵信息。
这里,基站获取其它基站配置的至少一个小区的VAM矩阵信息的方式可以是:获取RNC发送的其它基站下的至少一个小区的VAM矩阵信息。在具体实施中,任一基站可以将配置的至少一个小区的VAM矩阵信息上报给对应的RNC,该RNC可以将该任一基站配置的至少一个小区的VAM矩阵信息发送给管理的其它基站,或者将该任一基站配置的至少一个小区的VAM矩阵信息发送给其它RNC,由其它RNC发送给其它RNC管理下的基站。
S1002:基站通过物理层信令,将所述至少一个小区的VAM矩阵信息通知给UE。
这里的物理层信令可以包括广播信令,或者专用控制信令,比如通过高速共享控制信道(High Speed-Shared Control Channel,HS-SCCH)通知给UE。
S1003:针对所述至少一个小区中的任一小区,所述UE基于该小区的VAM矩阵信息,对接收的该小区的多输入多输出MIMO信号进行解调。
具体地,若所述至少一个小区包括服务小区,则UE基于服务小区的VAM矩阵信息,对接收的该服务小区的MIMO信号进行解调;若所述至少一个小区包括邻小区,则UE基于邻小区的VAM矩阵信息,对接收的该邻小区的MIMO信号进行解调。
如图11所示,为本发明再一实施例提供的信息传输方法流程图,包括以下步骤:
S1101:服务基站确定发送MIMO信号的至少一个小区的VAM矩阵信息;所述至少一个小区包括UE的服务小区和/或至少一个邻小区;所述至少一个邻小区包括所述服务基站覆盖下的小区和/或所述UE的邻基站覆盖下的小区。
S1102:所述服务基站通过UE的服务小区,将所述至少一个小区的VAM矩阵信息通知给UE。
S1103:若所述至少一个小区包括服务小区,则UE基于服务小区的VAM 矩阵信息,对接收的该服务小区的MIMO信号进行解调;若所述至少一个小区包括邻小区,则UE基于邻小区的VAM矩阵信息,对接收的该邻小区的MIMO信号进行解调,以便实现邻小区干扰消除或者干扰抑制。
如图12所示,为本发明又一实施例提供的信息传输方法流程图,包括以下步骤:
S1201:UE的邻基站确定发送MIMO信号的至少一个小区的VAM矩阵信息;所述至少一个小区包括所述UE的至少一个邻小区;所述至少一个邻小区为所述邻基站覆盖下的小区。
S1202:所述邻基站通过覆盖下的小区,将所述至少一个小区的VAM矩阵信息通知给UE。
这里,邻基站可以通过覆盖下的一个小区,将所述至少一个小区的VAM矩阵信息都通知给UE,也可以分别通过所述至少一个小区中的每个小区,将每个小区自身的VAM矩阵信息通知给UE。
