Description

一种反馈信道状态信息CSI的方法及装置
本申请要求于2015年08月14日提交中国专利局、申请号PCT/CN2015/087091、发明名称为“一种反馈信道状态信息CSI的方法及装置”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本发明涉及通信技术领域,尤其涉及一种反馈信道状态信息的方法及装置。
背景技术
随着移动通信技术的发展,用户业务量和数据吞吐量不断增加,3G(the 3rd Generation,第三代移动通信系统)已不能完全满足用户要求。因此,3GPP(the 3rd Generation Partner Project,第三代合作伙伴计划)系统应用而生,3GPP系统致力于研究3GPP LTE(Long Term Evolution,长期演进)系统,作为3G系统的演进。
LTE-Advanced是在LTE基础上的技术演进,其支持与LTE系统的后向兼容性。在2007年召开的会议上LTE-Advanced已成为一个共享的概念。为了提供更高的数据速率,支持更多的用户业务和新的服务,LTE-Advanced在频点、带宽、峰值速率及兼容性等方面都有新的需求。利用MIMO(Multiple Input Multiple Output,多天线)技术能够有效提高系统性能,一方面MIMO技术能够获得分集增益,数据传输更加棒;另一方面,MIMO技术能够实现空间复用,即多个数据流的同时传输,使得频谱效率大幅提高。
MIMO技术一般需要在发射端获得CSI(Channel State Information,信道状态信息),但是,在发射端获取CSI一般通过信道的互易性或者反馈,在一些情况下,例如,FDD(Frequency Division Dual,频分双工)系统下,信道互易性较差,因此,一般通过CSI反馈获得。

CSI进程1 第一参考信号资源
CSI进程2 第二参考信号资源
CSI进程3 第三参考信号资源
从表1的CSI进程配置信息可以看出,CSI进程配置信息包括3个CSI进程,针对CSI进程1,根据第一参考信号资源,测量参考信号,获得第一CSI1;针对CSI进程2,根据第二参考信号资源,测量参考信号,获得第一CSI2;针对CSI进程3,根据第三参考信号资源,测量参考信号,获得第一CSI3;可以发送第一CSI1、第一CSI2,及第一CSI3;或者,也可以根据第一CSI1、第一CSI2,及第一CSI3确定出第二CSI,再发送第二CSI。
上述只是对步骤100-步骤120的一个举例说明,并不限定于此。
现有技术中,不管在任何场景下,第一CSI中都包括CQI(Channel Quality Indicator,信道质量指示),但是,在有些情况下,第一CQI中不需要包括CQI,如果按照现有技术仍要包括CQI的话,会存在资源浪费的缺陷,因此,为了避免资源浪费,本发明实施例中,第一CSI不包括CQI。
现有技术中,一个CSI进程只能与一个参考信号资源相关联,需要测量的参考信号较多时,则需要配置多个CSI进程。但是由于每个接收端可配置的CSI进程数量有限,因此,为了避免CSI进程数量限制以及提高资源利用率,至少一个CSI进程包括第一CSI进程,第一CSI进程与至少两个参考信号资源相关联。
此时,接收端在根据与任意一CSI进程相关联的参考信号资源,获得第一CSI时,可选的,可以采用如下方式:
接收端根据与第一CSI进程相关联的至少两个参考信号资源中的每一个 参考信号资源,分别获取第一CSI。
例如,CSI进程配置信息可以如表2所示。
表2 CSI进程配置信息
CSI进程 参考信号资源
CSI进程1 第一参考信号资源、第二参考信号资源
CSI进程2 第三参考信号资源、第四参考信号资源
CSI进程3 第五参考信号资源、第六参考信号资源、第七参考信号资源
从表1的CSI进程配置信息可以看出,CSI进程配置信息包括3个CSI进程,针对CSI进程1,根据第一参考信号资源,测量参考信号,获得第一CSI1,根据第二参考信号资源,测量参考信号,获得第一CSI2;针对CSI进程2,根据第三参考信号资源,测量参考信号,获得第一CSI3,根据第四参考信号资源,测量参考信号,获得第一CSI4;针对CSI进程3,根据第五参考信号资源,测量参考信号,获得第一CSI5,根据第六参考信号资源,测量参考信号,获得第一CSI6,根据第七参考信号资源,测量参考信号,获得第一CSI7。
本发明实施例中,可选的,与同一个CSI进程相关联的参考信号资源包括第一参考信号资源和第二参考信号资源,根据第一参考信号资源获取的第一CSI,与根据第二参考信号资源获取的第一CSI所包括的内容不相同。
其中,第一CSI所包括的内容可以为如下至少一种信息:RI(Rank Indicator,秩指示)、PMI(Precoding Matrix Indicator,预编码矩阵指示)、CQI、波束指示BI(Beam Indicator,波束指示),及PI(CSI-Process indicator,CSI进程指示)。
例如,第一CSI1包含PMI,第一CSI2包含RI和CQI;或者,第一CSI1包含PMI,第一CSI2包含PMI和CQI。
当然,一个CSI进程与至少两个参考信号资源相关联时,根据每一个参考信号资源获得的第一CSI所包括的参数是相同的,但是参数具体的值可以不同。
例如,CSI进程与3个参考信号资源相关联:第一参考信号资源、第二参考信号资源和第三参考信号资源,根据第一参考信号资源,获得第一CSI1;根据第二参考信号资源,获得第一CSI2;根据第三参考信号资源,获得第一CSI3,第一CSI1包括RI1/PMI1、CQI1;第一CSI2包括RI2/PMI2、CQI2;第一CSI3包括RI3/PMI3、CQI3,虽然第一CSI、第一CSI2和第一CSI3都包括RI/PMI和CQI,但是,RI1/PMI1、RI2/PMI2和RI3/PMI3的具体值可以不同,CQI1、CQI2和CQI3的具体值也可以不同。
本发明实施例中,可选的,与任意一CSI进程相关联的至少两个参考信号资源中的任意两个不同的参考信号资源所对应的至少一种如下信息不同:
时间信息、频率信息、天线端口信息、周期信息、预编码信息、OCC(Orthogonal Cover Code,正交掩码)码信息。
例如,有2个参考信号资源:第一参考信号资源、第二参考信号资源,其中:第一参考信号资源和第二参考信号资源对应的频率信息不同;或者,也可以是第一参考信号资源和第二参考信号资源对应的天线端口信息不同;或者,也可以是第一参考信号资源和第二参考信号资源对应的周期信息不同;或者,也可以是第一参考信号资源和第二参考信号资源对应的预编码信息不同。
现有技术中,若每一个参考信号资源都都要反馈CQI,但是,在有些情况下不需要反馈CQI,如果仍然反馈CQI的话,会存在浪费资源的缺陷,因此,为了避免资源浪费,一个CSI进程与至少两个参考信号资源相关联的话,根据至少两个参考信号资源分别获取的第一CSI中的至少一个第一CSI不包括CQI。
例如,CSI进程1与第一参考信号资源、第二参考信号资源和第三参考信号资源相关联,根据第一参考信号资源获得第一CSI1、根据第二参考信号资源获得第一CSI2、根据第三参考信号资源获得第一CSI3,如果当前场景下CSI中不需要包括CQI,则为了避免资源浪费,第一CSI1、第一CSI2和第一CSI3中可以有一个CSI不包括CQI,或者,也可以有两个CSI不包括CQI, 或者,也可以有三个CSI不包括CQI。
本发明实施例中,CSI进程配置信息包括至少两个CSI进程,至少两个CSI进程中的任意一CSI进程与至少一个参考信号资源相关联。
此时,根据与任意一CSI进程相关联的参考信号资源,获得第一CSI时,可选的,可以采用如下方式:
根据与任意一CSI进程相关联的至少一个参考信号资源中的任意一参考信号资源,分别获取第一CSI。
也就是说如果一个CSI进程与一个参考信号资源相关联的话,则获取一个第一CSI,如果一个CSI进程与N个参考信号资源相关联的话,则获取N个第一CSI,N大于或者等于2。
例如,CSI进程配置信息可以如表3所示。
表3 CSI进程配置信息
CSI进程 参考信号资源
CSI进程1 第一参考信号资源
CSI进程2 第二参考信号资源、第三参考信号资源
CSI进程3 第四参考信号资源、第五参考信号资源、第六参考信号资源
从表3的CSI进程配置信息可以看出,CSI进程配置信息包括3个CSI进程,针对CSI进程1,根据第一参考信号资源,测量参考信号,获得第一CSI1;针对CSI进程2,根据第二参考信号资源,测量参考信号,获得第一CSI2,根据第三参考信号资源,测量参考信号,获得第一CSI3;针对CSI进程3,根据第四参考信号资源,测量参考信号,获得第一CSI4;,根据第五参考信号资源,测量参考信号,获得第一CSI5,根据第六参考信号资源,测量参考信号,获得第一CSI6。
然后,可以将第一CSI1、第一CSI2、第一CSI3、第一CSI4、第一CSI5和第一CSI6都进行反馈,或者,从第一CSI1、第一CSI2、第一CSI3、第一CSI4、第一CSI5和第一CSI6中选择出一个第一CSI进行反馈,或者,将第一CSI1、第一CSI2、第一CSI3、第一CSI4、第一CSI5和第一CSI6合成进 行反馈。
本发明实施例中,接收端根据第一CSI确定第二CSI时,可选的,可以采用如下方式:
接收端从获得的至少两个第一CSI中选择出第一CSI,将选择出的第一CSI作为第二CSI;或者
接收端将获得的至少两个第一CSI合成第二CSI。
其中,从获得的至少两个第一CSI中选择第一CSI时,可以从获得的至少两个第一CSI中选择出符合条件的第一CSI,将符合条件的第一CSI作为选择出的第一CSI。
其中,符合条件的第一CSI可以满足如下至少一个条件的第一CSI:
CQI为最大值、吞吐量为最大值、SINR(Signal to Interference plus Noise Ratio,信号与干扰加噪声比)为最大值。
仍以表3所描述的CSI进程配置信息为例进行说明。
例如,根据表3所描述的CSI进程配置信息,可以得出6个第一CSI:第一CSI1、第一CSI2、第一CSI3、第一CSI4、第一CSI5、第一CSI6,其中,6个第一CSI中第一CSI3的吞吐量为最大值,则将第一CSI3作为第二CSI,并将第二CSI发送;如果第一CSI6的吞吐量为最大值,则将第一CSI6作为第二CSI,并将第二CSI发送。
又例如,根据参考信号资源获得第一CSI1,第一CSI2,第一CSI1对应水平向信道参数,第一CSI2对应垂直向信道参数;其中,第一CSI1包括RI1、PMI1,第一CSI2包括RI2、PMI2;其中,PMI1对应预编码矩阵W1,PMI2对应预编码矩阵W2,则第二CSI中的PMI对应的预编码矩阵为
Figure PCTCN2015093280-appb-000001
其中,
Figure PCTCN2015093280-appb-000002
为克罗内科运算符,也可以通过R11*RI2获得第二CSI对应的RI,其中,*为乘法运算符。可选的,第二CSI对应的CQI根据第二CSI对应的PMI获得。
其中,当预编码矩阵W1为一列时,PMI1对应的就不是一个矩阵,而是一个向量了,因此,PMI1可以是与预编码矩阵相对应,也可以是与向量相对 应。
同理,当预编码矩阵W2为一列时,PMI2对应的就不是一个矩阵,而是一个向量了,因此,PMI2可以是与预编码矩阵相对应,也可以是与向量相对应。
需要说明的是,上述描述的第一CSI1,第一CSI2分别对应水平向信道参数和垂直向信道参数,只是一种具体的情况,并不限定于第一CSI1只能对应水平向信道参数,第一CSI2只能对应垂直向信道参数。
其中,第二CSI所包括的内容可以为如下至少一种信息:
RI、PMI、CQI、BI,及PI。
在有些场景下,发送的第二CSI不需要包括CQI,如果仍然包括CQI的话,会存在浪费资源的缺陷,因此,为了避免资源浪费,第二CSI不包括CQI。
上面描述了第一CSI或者第二CSI不包括CQI,但是,第一CSI或者第二CSI可以包括如下内容:
例如,第一CSI包括RI和/或PMI;或者,第二CSI包括RI和/或PMI。
当然,如果CSI进程配置信息包括至少两个CSI进程时,至少一个CSI进程包括第一CSI进程,第一CSI进程与两个参考信号资源相关联。
例如,CSI进程配置信息可以如表4所示。
表4 CSI进程配置信息
CSI进程 参考信号资源
CSI进程1 第一参考信号资源、第二参考信号资源
CSI进程2 第三参考信号资源、第四参考信号资源
CSI进程3 第五参考信号资源、第六参考信号资源
为了对于干扰信号做测量,任意一CSI进程还与干扰测量资源相关联。
接收端根据与任意一CSI进程相关联的参考信号资源,获得第一CSI时,可选的,可以采用如下方式:
接收端根据与任意一CSI进程相关联的参考信号资源和干扰测量资源,获得第一CSI。
可选的,至少一个CSI进程包括第一CSI进程,第一CSI进程还与至少两个干扰测量资源相关联;
可选的,此时,接收端根据与任意一CSI进程相关联的参考信号资源,获得第一CSI时,可以采用如下方式:
接收端根据与第一CSI进程相关联的参考信号资源和至少两个干扰测量资源,获得第一CSI。
本发明实施例中,可选的,接收端未被配置至少两个子帧集。
为了提高CSI测量与反馈配置的灵活性,以及便于测得多个资源或者用户相互之间的干扰,或者小区内以及小区外用户之间的干扰,提高CSI的测量精度,本发明实施例中,可选的,接收端被配置至少两个子帧集,其中,至少两个子帧集包括第一子帧集,第一子帧集与至少两个干扰测量资源相关联。
或者,也可以是每个子帧集与至少两个干扰测量资源相关联。
需要说明的是,上述所说的至少两个干扰测量资源可以对应同一个CSI进程。
本发明实施例中,可选的,接收端被配置至少两个子帧集,其中,至少两个子帧集包括第二子帧集,第二子帧集与至少一个参考信号资源相关联。
可选的,与所述CSI进程相关联的至少一个参考信号资源中至少包含两个参考信号资源对应同一个子帧集。
本发明实施例中,可选的,子帧集为CSI子帧集,或者,也可以是其他子帧。
本发明实施例中,可选的,与CSI进程相关联的参考信号资源与干扰测量资源的数量相同。
本发明实施例中,可选的,与任意一CSI进程相关联的参考信号资源与干扰测量资源对应,其中一个参考信号资源与一个干扰测量资源相对应,且参考信号资源中的任意两个不同的参考信号资源所对应的干扰测量资源不相同。
例如,第一参考信号资源对应第一干扰测量资源,第二参考信号资源对应第二干扰测量资源。
可选的,与所述CSI进程相关联的至少一个参考信号资源中包含一个参考信号资源与至少两个干扰测量资源相对应。例如,第三参考信号资源与第三干扰测量资源以及第四干扰测量资源相关联。
本发明实施例中,可选的,CSI进程配置信息包括至少两个CSI进程,至少两个CSI进程中的任意一CSI进程与至少一个参考信号资源相关联,其中,至少一个CSI进程对应的参考信号资源与发送的CSI不相关,或者,其中,至少一个CSI进程对应的参考信号资源对应的CSI与另外一个CSI进程相关联。
例如,CSI进程配置信息包括第一CSI进程和第二CSI进程,其中第一CSI进程与第一参考信号资源相关联,第二CSI进程与第二参考信号资源相关联,根据第一参考信号资源获得第一CSI1,根据第二参考信号获得第一CSI2;反馈的CSI可以为第一CSI1,此时,第一CSI1可以在第一CSI进程中反馈,也可以在第二CSI进程中反馈,或者由第一CSI1和第一CSI2合成一个第二CSI,并在第一CSI进程中反馈。
在实际应用中,发送CSI需要用到反馈资源,因此,进一步的,任意一CSI进程还与反馈资源相关联;
可选的,反馈资源至少包括其中一个:CSI的内容、CSI对应的时域资源、CSI对应的频域资源、CSI对应的反馈周期、CSI对应的PUSCH(Physical Uplink Shared Channel,物理上行共享信道)资源,及CSI对应的PUCCH(Physical Uplink Control CHannel,物理上行链路控制信道)资源。
可选的,CSI的内容包括PMI、RI、CQI、BI、PI中的至少一种。此时,发送第一CSI时,可选的,可以采用如下方式:
根据与至少一个CSI进程相关联的反馈资源,发送第一CSI;
此时,发送第二CSI时,可选的,可以采用如下方式:
根据与至少一个CSI进程相关联的反馈资源,发送第二CSI。
现有技术中,每一个CSI进程得到的CSI都要进行反馈,例如,CSI进程1得到一个CSI,为第一CSI1;CSI进程2得到一个CSI,为第一CSI2;CSI进程3得到一个CSI,为第一CSI3;第一CSI1、第一CSI2和第一CSI3均需要进行反馈,第一CSI1在CSI进程1对应的反馈资源1上进行反馈、第一CSI2在CSI进程2对应的反馈资源2上进行反馈,第一CSI3在CSI进程3对应的反馈资源3上进行反馈,但是,在有些场景下,只需要从第一CSI1、第一CSI2和第一CSI3中选择出一个第一CSI进行反馈,或者是将第一CSI1、第一CSI2和第一CSI3合成一个第二CSI进行反馈,那么,此时,就没必要给每一个CSI进程配置对应的反馈资源。
因此,为了避免资源浪费,可以对m个CSI进程配置n个相关联的反馈资源,m大于或者等于1,n大于或者等于1且小于m。
例如,CSI进程配置信息包括2个CSI进程,第一CSI进程与第一参考信号资源和反馈资源相关联,第二CSI进程与第二参考信号资源相关联,第一CSI进程根据第一参考信号资源,得到第一CSI1,第二CSI进程根据第二参考信号资源,得到第一CSI2;从第一CSI1和第一CSI2中选择出符合条件的第一CSI是第一CSI1,则将第一CSI1在与第一CSI进程相关联的反馈资源上进行反馈;或者,从第一CSI1和第一CSI2中选择出符合条件的第一CSI是第一CSI2,则将第一CSI2在与第一CSI进程相关联的反馈资源上进行反馈;或者,将第一CSI1和第一CSI2合成第二CSI,则将第二CSI在与第一CSI进程相关联的反馈资源上进行反馈。
进一步的,还需要说明反馈的第一CSI是哪个CSI进程得到的,例如,可以携带得到反馈的第一CSI的CSI进程的标识。
当然,也可以与反馈资源相关联的CSI进程,和与反馈的第一CSI相关联的CSI进程,不是同一CSI进程的情况下,再说明反馈的第一CSI是哪个CSI进程得到的。
例如,CSI进程配置信息包括2个CSI进程,2个CSI进程均有对应的标识,第一CSI进程与第一参考信号资源和反馈资源相关联,第二CSI进程与 第二参考信号资源相关联,第一CSI进程根据第一参考信号资源,得到第一CSI1,第二CSI进程根据第二参考信号资源,得到第一CSI2,从第一CSI1和第一CSI2中选择出的是第一CSI1,则将第一CSI1在与第一CSI进程相关联的反馈资源上进行反馈,此时,可以在反馈第一CSI1的时候,携带第一CSI进程的标识,当然,也可以不携带;从第一CSI1和第一CSI2中选择出的是第一CSI2,则将第一CSI2在与第一CSI进程相关联的反馈资源上进行反馈,此时,可以在反馈第一CSI2的时候,携带第二CSI进程的标识。
从上述举例就可以看出,如果第一CSI进程和第二CSI进程都配置反馈资源的话,存在资源浪费的情况,因此,如果只是第一CSI进程和第二CSI进程中的只有一个CSI进程与反馈资源相关的话,会避免资源浪费,提高资源的利用率。
当一个CSI进程与多个参考信号资源相关联时,如果不知道该CSI进程与几个参考信号资源相关联的话,可能不会利用与该CSI进程相关联的所有参考信号资源去测量,这样,存在资源浪费的情况。
例如,第一CSI进程与2个参考信号资源相关联:第一参考信号资源和第二参考信号资源,由于不知道与2个参考信号资源相关联,只根据第一参考信号资源测量,得到第一CSI1,这样,第二参考信号资源就存在浪费的情况。
因此,为了避免资源浪费,CSI进程配置信息还包括,与至少一个CSI进程中的每一个CSI进程分别相关联的参考信号资源的数量;
此时,根据与任意一CSI进程相关联的参考信号资源,获得第一CSI时,可选的,可以采用如下方式:
根据与任意一CSI进程对应的数量的参考信号资源中的每一个参考信号资源,分别获得对应的第一CSI。
本发明实施例中,可选的,接收CSI进程配置信息时,可以采用如下方式:
通过RRC(Radio Resource Control,无线资源控制)消息或者DCI (Downlink Control Information,下行控制信息),接收CSI进程配置信息。
上述描述的是,接收端接收到的CSI进程配置信息包括的CSI进程与参考信号资源相关联,但是,在实际应用中,接收端还可能接收到其他CSI进程配置信息,其他CSI进程配置信息包括的CSI进程可以不予参考信号资源相关联,与干扰测量资源相关联,或者,与反馈资源相关联,或者,与干扰测量资源和反馈资源相关联。
也就是说,接收端配置的CSI进程可能与参考信号资源相关联,或者,也可能不与参考信号资源相关联,在不与参考信号资源相关联的情况下,可能与干扰测量资源,和/或反馈资源相关联。
本发明实施例中所说的参考信号可以是CSI参考信号,也可以是其它参考信号,在此不做具体限定。
参阅图2所示,本发明实施例中,反馈CSI的一种流程如下:
步骤200:发送端发送CSI进程配置信息,CSI进程配置信息包括至少一个CSI进程,至少一个CSI进程中的任意一CSI进程分别与参考信号资源相关联;
步骤210:发送端接收第一CSI,或者,发送端接收第二CSI,第二CSI是根据第一CSI确定的;第一CSI是根据与任意一CSI进程相关联的参考信号资源获得的。
以表1为例进行说明。从表1的CSI进程配置信息可以看出,CSI进程配置信息包括3个CSI进程,针对CSI进程1,接收端根据第一参考信号资源,测量参考信号,获得第一CSI1;针对CSI进程2,接收端根据第二参考信号资源,测量参考信号,获得第一CSI2;针对CSI进程3,接收端根据第三参考信号资源,测量参考信号,获得第一CSI3;则发送端接收到的可以是第一CSI1、第一CSI2,及第一CSI3;或者,接收到的也可以是根据第一CSI1、第一CSI2,及第一CSI3确定出的第二CSI。
上述只是对步骤200-步骤210的一个举例说明,并不限定于此。
现有技术中,不管在任何场景下,第一CSI中都包括CQI,但是,在有 些情况下,第一CQI中不需要包括CQI,如果按照现有技术仍要包括CQI的话,会存在资源浪费的缺陷,因此,为了避免资源浪费,本发明实施例中,第一CSI不包括CQI。
现有技术中,一个CSI进程只能与一个参考信号资源相关联,需要测量的参考信号较多时,则需要配置多个CSI进程。但是由于每个接收端可配置的CSI进程数量有限,因此,为了避免CSI进程数量限制以及提高资源利用率,至少一个CSI进程包括第一CSI进程,第一CSI进程与至少两个参考信号资源相关联。
本发明实施例中,可选的,至少两个参考信号资源包括第一参考信号资源和第二参考信号资源,根据第一参考信号资源获取的第一CSI,与根据第二参考信号资源获取的第一CSI内容不相同。
其中,第一CSI所包括的内容可以为如下至少一种信息:
RI、PMI、CQI、BI,及PI。
例如,第一CSI1包含PMI,第一CSI2包含RI和CQI;或者,第一CSI1包含PMI,第一CSI2包含PMI和CQI。
也就是说,如果一个CSI进程与多个参考信号资源相关联的话,根据每一个参考信号资源获得的第一CSI所包括的参数是相同的,但是参数具体的值可以不同。
例如,CSI进程与3个参考信号资源相关联:第一参考信号资源、第二参考信号资源和第三参考信号资源,根据第一参考信号资源,获得第一CSI1;根据第二参考信号资源,获得第一CSI2;根据第三参考信号资源,获得第一CSI3,第一CSI1包括RI1/PMI1、CQI1;第一CSI2包括RI2/PMI2、CQI2;第一CSI3包括RI3/PMI3、CQI3,虽然第一CSI、第一CSI2和第一CSI3都包括RI/PMI和CQI,但是,RI1/PMI1、RI2/PMI2和RI3/PMI3的具体值可以不同,CQI1、CQI2和CQI3的具体值也可以不同。
本发明实施例中,可选的,至少两个参考信号资源中的任意两个不同的参考信号资源所对应的至少一种如下信息不同:
时间信息、频率信息、天线端口信息、周期信息、预编码信息,及OCC码信息。
例如,有2个参考信号资源:第一参考信号资源、第二参考信号资源,其中:第一参考信号资源和第二参考信号资源对应的频率信息不同;或者,也可以是第一参考信号资源和第二参考信号资源对应的天线端口信息不同;或者,也可以是第一参考信号资源和第二参考信号资源对应的周期信息不同;或者,也可以是第一参考信号资源和第二参考信号资源对应的预编码信息不同。
本发明实施例中,可选的,CSI进程配置信息包括至少两个CSI进程,至少两个CSI进程中的任意一CSI进程与至少一个参考信号资源相关联。
例如,CSI进程配置信息可以如表3所示。
本发明实施例中,第二CSI可以从至少两个第一CSI中选择出的,也可以是由至少两个第一CSI合成的。
其中,从至少两个第一CSI中选择出的第一CSI,可以为满足如下至少一个条件的第一CSI:
CQI为最大值、吞吐量为最大值、SINR(Signal to Interference plus Noise Ratio,信号与干扰加噪声比)为最大值。
仍以表3所描述的CSI进程配置信息为例进行说明。
例如,根据表3所描述的CSI进程配置信息,可以得出6个第一CSI:第一CSI1、第一CSI2、第一CSI3、第一CSI4、第一CSI5、第一CSI6,其中,6个第一CSI中第一CSI3的吞吐量为最大值,则将第一CSI3作为第二CSI,并将第二CSI发送;如果第一CSI6的吞吐量为最大值,则将第一CSI6作为第二CSI。
又例如,根据参考信号资源获得第一CSI1,第一CSI2,第一CSI1对应水平向信道参数,第一CSI2对应垂直向信道参数;其中,第一CSI1包括RI1、PMI1,第一CSI2包括RI2、PMI2;其中,PMI1对应预编码矩阵W1,PMI2对应预编码矩阵W2,则第二CSI中的PMI对应的预编码矩阵为
Figure PCTCN2015093280-appb-000003
其中,
Figure PCTCN2015093280-appb-000004
为克罗内科运算符,也可以通过R11*RI2获得第二CSI对应的RI,其中,*为乘法运算符。可选的,第二CSI对应的CQI根据第二CSI对应的PMI获得。
其中,当预编码矩阵W1为一列时,PMI1对应的就不是一个矩阵,而是一个向量了,因此,PMI1可以是与预编码矩阵相对应,也可以是与向量相对应。
同理,当预编码矩阵W2为一列时,PMI2对应的就不是一个矩阵,而是一个向量了,因此,PMI2可以是与预编码矩阵相对应,也可以是与向量相对应。
需要说明的是,上述描述的第一CSI1,第一CSI2分别对应水平向信道参数和垂直向信道参数,只是一种具体的情况,并不限定于第一CSI1只能对应水平向信道参数,第一CSI2只能对应垂直向信道参数。
其中,第二CSI所包括的内容可以为如下至少一种信息:
RI、PMI、CQI、BI,及PI。
现有技术中,每一个CSI中都包括CQI,但是,在有些情况下不需要包括CQI,如果仍然包括CQI的话,会存在浪费资源的缺陷,因此,为了避免资源浪费,第二CSI不包括CQI。
上面描述了第一CSI或者第二CSI不包括CQI,但是,第一CSI或者第二CSI可以包括如下内容:
第一CSI包括RI和/或PMI;或者,第二CSI包括RI和/或PMI。
当然,如果CSI进程配置信息包括至少两个CSI进程时,本发明实施例中,至少一个CSI进程包括第一CSI进程,第一CSI进程与两个参考信号资源相关联。
例如,CSI进程配置信息可以如表4所示。
本发明实施例中,进一步的,任意一CSI进程还与干扰测量资源相关联。
本发明实施例中,进一步的,任意一CSI进程还与至少两个干扰测量资源相关联。
本发明实施例中,可选的,发送端未对特定接收端配置至少两个子帧集。
为了提高CSI测量与反馈配置的灵活性,以及便于测得多个资源或者用户相互之间的干扰,或者小区内以及小区外用户之间的干扰,提高CSI的测量精度,本发明实施例中,可选的,发送端对特定接收端配置至少两个子帧集,其中,至少两个子帧集包括第一子帧集,第一子帧集与至少两个干扰测量资源相关联。
或者,也可以是每个子帧集与至少两个干扰测量资源相关联。
需要说明的是,上述所说的至少两个干扰测量资源可以对应同一个CSI进程。
本发明实施例中,可选的,发送端对特定接收端配置至少两个子帧集,其中,至少两个子帧集包括第二子帧集,第二子帧集与至少一个参考信号资源相关联。
可选的,与所述CSI进程相关联的至少一个参考信号资源中至少包含两个参考信号资源对应同一个子帧集。
本发明实施例中,可选的,子帧集为CSI子帧集,或者,也可以是其他子帧。
本发明实施例中,可选的,与CSI进程相关联的参考信号资源与干扰测量资源的数量相同。
本发明实施例中,可选的,与任意一CSI进程相关联的参考信号资源与干扰测量资源对应,其中一个参考信号资源与一个干扰测量资源相对应,且参考信号资源中的任意两个不同的参考信号资源所对应的干扰测量资源不相同。
例如,第一参考信号资源对应第一干扰测量资源,第二参考信号资源对应第二干扰测量资源。
可选的,与所述CSI进程相关联的至少一个参考信号资源中包含一个参考信号资源与至少两个干扰测量资源相对应。例如,第三参考信号资源与第三干扰测量资源以及第四干扰测量资源相关联。
本发明实施例中,可选的,CSI进程配置信息包括至少两个CSI进程,至少两个CSI进程中的任意一CSI进程与至少一个参考信号资源相关联,其中,至少一个CSI进程对应的参考信号资源与发送的CSI不相关,或者,其中,至少一个CSI进程对应的参考信号资源对应的CSI与另外一个CSI进程相关联。
例如,CSI进程配置信息包括第一CSI进程和第二CSI进程,其中第一CSI进程与第一参考信号资源相关联,第二CSI进程与第二参考信号资源相关联,第一CSI1是根据第一参考信号资源获得的,第一CSI2是根据第二参考信号获得的;反馈的CSI可以为第一CSI1,此时,第一CSI1可以在第一CSI进程中反馈,也可以在第二CSI进程中反馈,或者由第一CSI1和第一CSI2合成一个第二CSI,并在第一CSI进程中反馈。
在实际应用中,发送CSI需要用到反馈资源,因此,进一步的,任意一CSI进程还与反馈资源相关联。
可选的,反馈资源至少包括其中一个:CSI的内容、CSI对应的时域资源、CSI对应的频域资源、CSI对应的反馈周期、CSI对应的PUSCH(Physical Uplink Shared Channel,物理上行共享信道)资源,及CSI对应的PUCCH(Physical Uplink Control Channel,物理上行链路控制信道)资源。
可选的,CSI的内容包括PMI、RI、CQI、BI、PI中的至少一种。
现有技术中,每一个CSI进程得到的CSI都要进行反馈,例如,CSI进程1得到一个CSI,为第一CSI1;CSI进程2得到一个CSI,为第一CSI2;CSI进程3得到一个CSI,为第一CSI3;第一CSI1、第一CSI2和第一CSI3均需要进行反馈,第一CSI1在CSI进程1对应的反馈资源1上进行反馈、第一CSI2在CSI进程2对应的反馈资源2上进行反馈,第一CSI3在CSI进程3对应的反馈资源3上进行反馈,但是,在有些场景下,只需要从第一CSI1、第一CSI2和第一CSI3中选择出一个第一CSI进行反馈,或者是将第一CSI1、第一CSI2和第一CSI3合成一个第二CSI进行反馈,那么,此时,就没必要给每一个CSI进程配置对应的反馈资源,即不是每一个CSI进程都与反馈资 源相关联。
因此,为了避免资源浪费,发送端在接收第一CSI或者接收第二CSI时,接收根据m个CSI进程配置的n个相关联的反馈资源发送的第一CSI或者第二CSI,m大于或者等于1,n大于或者等于1且小于m。
例如,CSI进程配置信息包括2个CSI进程,第一CSI进程与第一参考信号资源和反馈资源相关联,第二CSI进程与第二参考信号资源相关联,第一CSI1是根据第一CSI进程的第一参考信号资源得到的,第一CSI2是根据第二CSI进程的第二参考信号资源得到的;发送端接收到的是从第一CSI1和第一CSI2中选择出符合条件的第一CSI1,其中,第一CSI1是在与第一CSI进程相关联的反馈资源上进行反馈的;或者发送端接收到的是从第一CSI1和第一CSI2中选择出符合条件的第一CSI是第一CSI2,其中,第一CSI2是在与第一CSI进程相关联的反馈资源上进行反馈的;或者,发送端接收到的是由第一CSI1和第一CSI2合成得到的第二CSI,,其中,第二CSI是在与第一CSI进程相关联的反馈资源上进行反馈的。
需要说明的是,还需要说明反馈的第一CSI是哪个CSI进程得到的,例如,可以携带得到反馈的第一CSI的CSI进程的标识。
当然,也可以与反馈资源相关联的CSI进程,和与反馈的第一CSI相关联的CSI进程,不是同一CSI进程的情况下,再说明反馈的第一CSI是哪个CSI进程得到的。
例如,CSI进程配置信息包括2个CSI进程,2个CSI进程均有对应的标识,第一CSI进程与第一参考信号资源和反馈资源相关联,第二CSI进程与第二参考信号资源相关联,第一CSI1是根据第一CSI进程的第一参考信号资源得到的,第一CSI2是根据第二CSI进程的第二参考信号资源得到的,从第一CSI1和第一CSI2中选择出的是第一CSI1,则发送端接收到的第一CSI1是在与第一CSI进程相关联的反馈资源上进行反馈的,此时,可以在反馈第一CSI1的时候,携带第一CSI进程的标识,当然,也可以不携带;从第一CSI1和第一CSI2中选择出的是第一CSI2,则发送端接收到的第一CSI2是在 与第一CSI进程相关联的反馈资源上进行反馈,此时,可以在反馈第一CSI2的时候,携带第二CSI进程的标识。
从上述举例就可以看出,如果第一CSI进程和第二CSI进程都配置反馈资源的话,存在资源浪费的情况,因此,如果只是第一CSI进程和第二CSI进程中的只有一个CSI进程与反馈资源相关的话,会避免资源浪费,提高资源的利用率。
当一个CSI进程与多个参考信号资源相关联时,如果不知道该CSI进程与几个参考信号资源相关联的话,可能不会利用与该CSI进程相关联的所有参考信号资源去测量,这样,存在资源浪费的情况。
例如,第一CSI进程与2个参考信号资源相关联:第一参考信号资源和第二参考信号资源,由于不知道与2个参考信号资源相关联,只根据第一参考信号资源测量,得到第一CSI1,这样,第二参考信号资源就存在浪费的情况。
因此,为了避免资源浪费,CSI进程配置信息还包括,与至少一个CSI进程中的每一个CSI进程分别相关联的参考信号资源的数量。
本发明实施例中,可选的,发送端发送CSI进程配置信息时,可以采用如下方式:
发送端通过RRC消息或者DCI,发送CSI进程配置信息。
上述描述的是,发送端发送的CSI进程配置信息包括的CSI进程与参考信号资源相关联,但是,在实际应用中,发送端还可能发送其他CSI进程配置信息,其他CSI进程配置信息包括的CSI进程可以不予参考信号资源相关联,与干扰测量资源相关联,或者,与反馈资源相关联,或者,与干扰测量资源和反馈资源相关联。
也就是说,接收端配置的CSI进程可能与参考信号资源相关联,或者,也可能不与参考信号资源相关联,在不与参考信号资源相关联的情况下,可能与干扰测量资源,和/或反馈资源相关联。
可选的,一个CSI进程与多个干扰测量资源相关联,或者,一个CSI进 程与多个反馈资源相关联。
本发明实施例中所说的参考信号可以是CSI参考信号,也可以是其它参考信号,在此不做具体限定。

3:第一CSI或者第二CSI不包括CQI;
4:与至少两个参考信号资源相关联;

其中,符合条件的第一CSI可以满足如下至少一个条件的第一CSI:

参阅图4所示,本发明实施例中,反馈CSI的一种流程如下:
步骤400:发送端发送CSI进程配置信息,其中,CSI进程配置信息包括CSI进程类型信息,任意一CSI进程与参考信号资源相关联,任意一CSI进程属于CSI进程类型信息对应的CSI进程类型;
步骤410:发送端接收第一CSI;或者,发送端接收第二CSI,第二CSI是根据第一CSI确定的;第一CSI是根据与任意一CSI进程相关联的参考信号资源获得的。

需要说明的是,上述描述的只是CSI进程配置信息的几种具体的例子,并不限定于上述几种形式。
可选的,CSI进程类型信息包括下列信息中的至少一个:
与任意一CSI进程相关联的参考信号资源的数量、第一CSI所包括的信息、第二CSI所包括的信息、第二CSI的生成方式信息。
第一CSI所包括的信息,可选的,可以指第一CSI包括CQI、PMI、RI中的至少一种。
同理,第二CSI所包括的信息,可选的,可以指第二CSI包括CQI、PMI、RI中的至少一种。
可选的,第二CSI的生成方式信息指的是第二CSI是从第一CSI中选择得到的,还是根据第一CSI合成得到的。
可选的,第二CSI的确定类型指的是第二CSI是从第一CSI中选择得到的,还是根据第一CSI合成得到的。
本发明实施例中,可选的,CSI进程类型信息包括下列信息中的至少一个:

例如,子帧集序号为CCSI,0和CCSI,1

其中,第二CSI可以是至少两个第一CSI中符合条件的第一CSI,符号条件的第一CSI可以指满足如下至少一个条件的第一CSI:
CQI为最大值、吞吐量为最大值、SINR为最大值。
以表3所描述的CSI进程配置信息为例进行说明。
例如,根据表3所描述的CSI进程配置信息,可以得出6个第一CSI:第一CSI1、第一CSI2、第一CSI3、第一CSI4、第一CSI5、第一CSI6,其中,6个第一CSI中第一CSI3的吞吐量为最大值,则将第一CSI3作为第二CSI;如果6个第一CSI中第一CSI6的吞吐量为最大值,则将第一CSI6作为第二CSI。
本发明实施例中所说的参考信号可以是CSI参考信号,也可以是其它参考信号,在此不做具体限定。
在该方案中,由于CSI进程配置信息指示的是CSI进程类型信息,不是说每一个CSI进程是怎么样配置的,这样,提高了反馈CSI的效率,并降低了资源的消耗,提高资源的利用率。
本发明又一个实施例中,接收端在获得第一CSI的时候,具体为,接收端测量n个CSI-RS(Reference Signal,参考信号)以获得测量结果。
可选的,在接收端对该CSI-RS测量的过程中,每个CSI-RS都是对应某个CSI进程的。
例如,基站和用户设备确定共有k个CSI进程,其中,每个CSI进程均包含至少一个CSI-RS。
应理解,这里基站和用户设备确定共有k个CSI进程时,可以是基站和用户设备协商确定得到的;或者,也可以是基站或用户设备中的一个根据信道特性或者其它参数确定,,再通过信令或隐含指示的方式通知对方;或者,也可以是接收其它网元的信令,通过其它网元的信令来确定的。
需要说明的是,每个CSI进程均包含至少一个CSI-RS是指,基站和用户设备确定的一个CSI进程实际配置了至少一个CSI-RS。
要说明的是,用户设备测量n个信道状态信息参考信号CSI-RS以获得测量结果是指,即用户设备接收CSI-RS,并对接收的CSI-RS进行测量,以获得测量结果。
用户设备根据CSI-RS确定n个CSI,其中,每个CSI-RS对应一个CSI; 这里的确定是根据测量结果确定的,也可以直接根据接收到的CSI-RS确定的。通常,测量一个CSI-RS就确定出一个CSI。
进一步的,用户设备还要确定反馈CSI的方式。
在确定反馈CSI的方式的时候,可选的,可以是根据基站的配置确定的,具体可以是基站根据信令显式确定,或其它隐式地确定。
例如,用户设备接收一个配置信令,,具体在接收时可以通过字符串的长短或配置的进程特征接收。
一个实施例中,每个RS一一对应一个CSI-RS反馈资源。每个反馈资源用于反馈用户设备测量对应的CSI-RS后得到的CSI,但是,这样存在资源浪费的情况。
一个实施例中,有些参数在反馈的过程中是可以合并以节省资源的,例如,有两个CSI-RS分别为CSI-RS(A)和CSI-RS(B);CSI-RS(A)对应第一反馈资源,CSI-RS(B)对应第二反馈资源,用户设备测量CSI-RS(A)和CSI-RS(B)以获得测量结果,进一步获得根据CSI-RS(A)测量得到的CSI(A)和根据第二CSI-RS测量得到的CSI(B)。CSI(A)的PMI可以和CSI(B)的PMI联合反馈,在用户设备和eNB确认的情况下,用户设备可以在第一反馈资源中反馈CSI(A)中除PMI以外的参数,在第二反馈资源中反馈CSI(B)中除PMI以外的参数,还在第一反馈资源或第二反馈资源中的一个中反馈联合PMI。
应理解,联合PMI可以是同时包括第一PMI和第二PMI,也可以是一个合成的PMI。这样,基站就可以根据第一PMI和第二PMI分别确定第一PMI指示的第一预编码矩阵和第二PMI指示的第二预编码矩阵;或直接根据合成的PMI确定合成的预编码矩阵。这里第一PMI是第一CSI中的PMI,第二PMI是第二CSI中的PMI。
又例如,CSI(A)的CQI可以和CSI(B)的CQI联合反馈。用户设备可以在第一反馈资源中反馈CSI(A)中除CQI以外的参数,在第二反馈资源中反馈CSI(B)中除CQI以外的参数,还在第一反馈资源或第二反馈资源中的一个中反馈联合CQI。
应理解,联合CQI可以是同时包括第一CQI和第二CQI,也可以是一个合成的CQI,或第一CQI或第二CQI中的一个。这里第一CQI是第一CSI中的CQI,第二CQI是第二CSI中的CQI。
又一个实施例中,与每个CSI-RS一一对应一个反馈资源的实施例不同的是,在某些情况下,用户设备确定出多个CSI-RS可能对应同一个反馈资源,每个CSI-RS的反馈资源用于反馈用户设备测量对应的CSI-RS后得到的CSI。
例如,有两个CSI-RS分别为CSI-RS(C)和CSI-RS(D),CSI-RS(C)和CSI-RS(D)对应同一个反馈资源,在这种情况下,PMI可以采用上述的联合反馈方式,CQI也可以采用上述联合的反馈方式,RI或其它参数可以在同一资源上反馈。用户设备根据反馈方式向eNB发送n个CSI。
本发明实施例中,进一步的,CSI进程类型信息对应的CSI进程类型包括第六CSI进程类型,第六CSI进程类型包括的CSI进程满足如下规则:
CSI进程与一个参考信号资源和一个干扰测量资源相关联。
本发明实施例中,进一步的,CSI进程类型信息对应的CSI进程类型包括第七CSI进程类型,第七CSI进程类型包括的CSI进程满足如下规则:
CSI进程与至少一个参考信号资源和至少两个干扰测量资源相关联。
本发明实施例中,进一步的,CSI进程类型信息对应的CSI进程类型包括第八CSI进程类型,第八CSI进程类型包括的CSI进程满足如下规则:
CSI进程与至少两个参考信号资源和至少一个干扰测量资源相关联。
本发明实施例中,进一步的,CSI进程类型信息对应的CSI进程类型包括第九CSI进程类型,第九CSI进程类型包括的CSI进程满足如下规则:
CSI进程与至少一个参考信号资源相关联,与干扰测量资源不相关联。
需要说明的是,基站可以是eNB(evolved Node B,演进型基站),也可以是BS(Base Station,基站),随着通信技术的发展,也可以是其它网络架构下的基站。
用户设备可以是UE(User Equipment),具体如手机、pad(Portable Android Device,平板电脑)等职能设备。
