Description

一种信道状态信息的上报方法、用户设备和基站 技术领域
本发明涉及通信领域,尤其涉及一种信道状态信息的上报方法、用户设备和基站。
背景技术
在无线通信领域,信道状态信息(Channel State Information,CSI)是通信链路的信道属性,可以包括预编码矩阵指示(Precoding Matrix Indicator,PMI)、秩指示(Rank Indication,RI)以及信道质量指示(Channel Quality Indicator,CQI),用户设备(User Equipment,UE)可以通过信道测量向基站上报CSI,这样基站就可以根据UE上报的CSI进行下行调度。
目前,CSI的上报分为周期CSI上报和非周期CSI上报。针对非周期CSI上报,在第三代合作伙伴计划无线接入网(3rd Generation Partnership Project Radio Access NetWork,3GPP RAN)66次会议以前,UE最多有5个载波聚合,如果基站触发所有载波的非周期CSI上报,基站在通过下行物理控制信道(Physical Downlink Control Channel,PDCCH)承载向UE发送的控制信息中包括有2bits的4种状态的CSI请求字段,以调度UE不上报或者上报哪些CSI集合。例如,该2bits为00时表示基站此次并不触发非周期的CSI上报,01表示只触发调度上行载波的CSI,10表示触发调度高层配置的第一个CSI上报集合,11表示触发高层配置的第二个CSI上报集合,且每个集合中包括哪些载波的CSI都是固定的。
但是,在3GPP RAN66次会议上大数量成员载波的载波聚合研究项目被通过,希望可以支撑UE最多聚合32个载波同时工作,这样,如果继续采用4种状态的CSI请求字段来上报CSI,且每个CSI上报集合中包括哪些载波的CSI是固定的,如果要均衡UE上报CSI的负载,每个CSI集合会包括较少的CSI,那么有可能使得不同载波的CSI不能上报给基站,基站便不能获知到部分信道的信道测量 信息,使得CSI的上报不灵活。

图3为本发明又一实施例提供的一种用户设备的结构示意图;
图4为本发明又一实施例提供的一种基站的结构示意图。
具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
本发明实施例可以应用于长期演进(Long Term Evolution,LTE)***,或通用移动通信***陆地无线接入网(Universal Mobile Telecommunication System Territorial Radio Access Network,UTRAN)***,也可以应用于无线宽带(WIreless-Fidelity,WIFI)***等,本发明不做限定。
在本发明实施例中,用户设备(User Equipment,UE)可以为以下任意一种,并且UE可以是静态的,也可以是移动的。UE可以 包括但不限于:站台(Station)、移动台(Mobile Station)、用户单元(Subscriber Unit)、个人电脑(Personal Computer)、膝上型电脑(Laptop Computer)、平板电脑(Tablet Computer)、上网本(Netbook)、终端(Terminal)、蜂窝电话(Cellular Phone)、手持设备(Handheld)、无绳电话(Cordless Phone)、个人数字助理(Personal Digital Assistant,缩写:PDA)、数据卡(Data Card)、通用串行总线(Universal Serial Bus,缩写:USB)***设备、移动WiFi热点设备(MiFi Devices)、智能手表、智能眼镜、无线调制解调器(英文:Modem)、无线路由器、无线本地环路(Wireless Local Loop,缩写:WLL)台等;基站(NodeB)可以为LTE网络中的基站,或UTRAN网络中的基站等。
本发明下述实施例可以适用于大数量载波聚合的场景,例如UE最多可聚合32个载波同时工作。
本发明实施例提供一种信道状态信息的上报方法,如图1所示,包括:
101、UE接收基站发送的控制信息,所述控制信息包含第一CSI请求指示。
其中,控制信息可以是基站向UE发送的下行控制信息(Downlink Control Infornation,DCI),其中可包括CSI请求指示,用于调度UE上报非周期CSI或不上报非周期CSI,以便于基站根据UE上报的CSI获知信道的即时状态,使通信***适应当前的信道条件,在多天线***中为高可靠性高速率的通信提供保障。
CSI可以包括PMI、RI和CQI等,因此,对于CQI来说,也可以认为是周期CQI上报和非周期CQI上报。其中,从基站侧来看,非周期CQI的上报时机较为复杂,可能是当某个小区有下行数据需要发送时触发的,也可能是当UE需要发送数据的子帧正好与CQI上报时间相同,此时的CQI在物理上行共享信道(Physical Uplink Shared Channel,PUSCH)信道承载,为了得到更详细的CQI报告,基站会触发非周期上报模式等。
需要说明的是,本发明这里的CSI请求指示并不限定于以2个比特表示,例如当采用32载波聚合时,可以采用下行控制信息DCI不同的格式来表示,或采用DCI中携带的MCS表示不同的指示等等,本发明不做限定。
102、所述UE根据CSI请求指示与CSI集合类型的映射关系获取与所述第一CSI请求指示对应的第一CSI集合类型,其中,所述CSI请求指示用于指示所述UE上报非周期CSI。
其中,本发明实施例中的CSI集合类型可理解为用于指示CSI集合的指示信息,例如CSI请求指示(CSI request field)为“001”,与“001”对应的CSI集合类型为“触发高层配置的第一个CSI集合上报”。其中,CSI集合表示用于上报CSI的对象的集合;该对象例如可以是载波,CSI进程以及子帧集合中的至少一种。例如,这里的第一个CSI集合为对象可以是CSI进程与子帧集合。
当CSI请求指示用于调度UE上报非周期CSI时,由于在UE当中保存有CSI请求指示与CSI集合类型的映射关系,UE便可根据该映射关系获取相应的CSI,例如这里的映射关系可以是不同的CSI请求指示与不同的CQI集合类型之间的映射。不同的CSI集合类型对应不同的CSI集合。
其中,该映射关系可以是采用提前约定的方式在UE与基站中预先配置的,也可以是基站向UE发送配置信令通知给UE保存的,同样对于CSI请求指示与CSI集合来说,CSI请求指示的类型与CSI集合也可以是采用提前约定的方式在UE与基站中预先配置的,也可以是基站向UE发送配置信令通知给UE保存的。
需要说明的是,本发明中的CSI集合可以是多样的,例如可按照不同的波段对载波进行分组,这样载波上承载的CSI也就归属到了不同的载波组中了,也可按照载波进行分组,例如可将32个载波按照载波标识将前16个载波归为一组,将后16个载波归为一组,也可以按其他的方式进行分组,本发明不对此进行限定。
103、所述向所述基站发送CSI测量报告,所述CSI测量报告包 括与所述第一CSI集合类型对应的非周期CSI。
例如,在UE获取到CSI请求指示对应的非周期CQI之后,向基站发送携带有非周期CQI的CQI测量报告,以便基站根据该CQI测量报告获知信道的即时状态。
下面对上述步骤101~步骤103进行具体说明。
进一步的,若上述映射关系为基站为UE通过信令配置的,在所述UE获取第一CSI集合类型之前,上述方法还包括:
所述UE接收所述基站发送的第一配置信令,其中,所述第一配置信令包括所述映射关系;
进而,所述UE获取所述第一CSI集合类型包括:
所述UE根据从所述第一配置信令接收的所述映射关系,获取与所述第一CSI请求指示对应的第一CSI集合类型。
当然,如果采用的是提前约定的方式,所述UE获取所述第一CSI集合类型包括:
所述UE根据所述UE预配置的所述映射关系,获取与所述第一CSI请求指示对应的第一CSI集合类型。
需要说明的是,所述CSI集合类型可以为载波集合的CSI,其中,所述载波集合对应承载所述控制信息的载波,或者,所述载波集合为承载所述控制信息的载波可调度的载波;或者
所述CSI集合类型可以为小区集合的CSI,其中,所述小区集合对应承载所述控制信息的小区,或者,所述小区集合为承载所述控制信息的小区可调度的小区。
当所述CSI集合为基站向UE通过信令配置的时,在所述UE获取所述第一CSI集合类型之前,还包括:
所述UE接收所述基站发送的第二配置信令,所述第二配置信令包括所述第一CSI集合类型对应的CSI集合;
这样,在所述UE向所述基站发送所述CSI测量报告之前,还 包括:
所述UE获取与所述第一CSI集合类型对应的CSI集合,所述非周期CSI为所述CSI集合对应的CSI。
其中,这里的CSI集合类型例如可以为:触发高层配置的第一CSI集合、触发高层配置的第二CSI集合等,进而根据第一CSI集合对应的CSI获取CSI集合。
当所述CSI集合的类型采用提前约定的方式时,在所述UE向所述基站发送所述CSI测量报告之前,还包括:
所述UE获取所述UE预配置的所述第一CSI集合类型对应的CSI集合,所述非周期CSI为所述CSI集合对应的CSI。
此外,当所述CSI请求指示的类型采用的是基站向UE发送配置信令获取的时,在所述UE获取第一CSI集合类型之前,还包括:
所述UE接收所述基站发送的第三配置信令,其中,所述第三配置信令包括所述CSI请求指示的类型;
所述UE根据所述CSI请求指示的类型,确定所述控制信息包含的所述CSI请求指示。
当所述CSI请求指示的类型采用的时提前约定的方式时,在所述UE获取所述第一CSI集合类型之前,还包括:
所述UE根据所述UE预配置的所述CSI请求指示的类型,确定所述控制信息包含的所述CSI请求指示。
进一步的,上述步骤中的CSI集合的分组可以采用不同的分组规则,使得不同的CSI集合类型对应不同的CSI集合,例如该CSI集合类型可以为以下中的至少一项:
a1:将载波按照载波标识分组后的同一个载波组的CSI,或为按照小区标识分组后的同一个小区组的CSI。例如,对于32载波聚合来说,可将32载波中标识为1~16的前16个载波归为一组,将标识为17~32的后16个载波归为一组,或对于聚合的32个载波上的 小区,可将32个载波中标识为1~16的前16个小区归为一组,将标识为17~32的后16个小区归为一组;
b1:将不同小区按照归属不同的物理上行链路控制信息(Physical Uplink Control Channel,PUCCH)分组后,属于同一个PUCCH组的小区的下行载波的CSI。例如,目前的R13版本中的增强载波聚合(Carrier Aggregation,CA)可以配置多个PUCCH,也就是不同的载波的控制信息,如确认消息,CSI消息等可在不同的PUCCH上向基站反馈,这样可以按照不同小区将属于同一个PUCCH的载波归为一个PUCCH组,也即将同一PUCCH组的载波的CSI归为一个集合;
c1:将载波按照不同的波段(band)进行分组后属于同一波段或同一波段组合的载波的CSI。例如按照电磁波频谱划分时,可将波段分为长波、短波和超短波等,这样属于不同波段的载波归为一个集合,也就将载波上的CSI分到了不同的集合当中;也可以将短波和超短波归为一组等;
d1:授权频谱载波的CSI或非授权频谱载波的CSI,这样授权频谱的载波上发送的CSI归为一个CSI集合,非授权频谱的载波上发送的CSI归为一个CSI集合;
e1:在为每个载波配置至少一个CSI进程后,按照不同的进程对载波分组后的同一载波组的CSI,例如,对于传输模式(Transmission Mode,TM)10的UE来说,可在每个载波上配置多个CSI进程,而后按照不同的进程对载波进行分组,这样同一载波组的CSI可归为一个CSI集合;
f1:在为每个载波配置不同的子帧集合后,按照不同的子帧集合对载波分组后的同一载波组的CSI。例如,可以在为每个载波配置不同的子帧集合,针对子帧的干扰度将子帧集合进行分组,属于同一子帧集合的载波上的CSI可归为一个CSI集合;
g1:宽带CQI所属的CSI或子带CQI所属的CSI,即根据CQI上报时为宽带CQI还是子带CQI对CSI进行分组。
h1:归属于同一个下行物理控制信道(Physical Downlink Control Channel,PDCCH)或增强下行物理控制信道(Enhanced Physical Downlink Control Channel,ePDCCH)调度的载波的CSI。
i1:不同载波上归属于同一天线端口的CSI。比如不同载波上天线端口1上的CSI都归为同一个CSI集合。
当然,上述多种CSI分组规则也可以采用任意两种或两种以上的组合方式进行分组,本发明不做限定。
针对上述步骤中的CSI请求指示的配置也可采用不同的指示规则,用以指示不同的CSI集合,例如可以为以下中的任一项:
a2:针对大数量载波聚合例如32载波聚合来说,可采用至少3个比特来实现更多的CSI请求指示映射到不同的CSI集合,这样可采用不同的3个比特信息表示不同的CSI请求指示,例如采用011表示第一个CSI集合等;
b2:CSI请求指示可采用控制信息,具体可为下行控制信息DCI的不同格式(format)表示,例如可将DCI格式中的1D、2A、1C等不同的格式与不同类型的CSI集合进行映射,也即使用不同的DCI格式表示不同的CSI请求指示;
c2:CSI请求指示可采用以表征上行调度的信息或下行调度的信息表示,以区分不同的CSI集合。例如以00表示上行调度时对应一个CSI集合,以01表示下行调度时对应一个CSI集合;
d2:CSI请求指示可采用DCI携带的调制与编码策略(Modulation and Coding Scheme,MCS)表示,例如采用不同的调制方式指示不同的CSI集合,或不同的编码方式指示不同的CSI集合;
e2:CSI请求指示可采用基站用于发送物理下行控制信道(Physical Downlink Control Channel,PDCCH)或增强物理下行控制信道ePDCCH(enhanced Physical Downlink Control Channel)的载波的载波标识表示。例如,在32载波聚合中,采用基站与UE之间的预先约定或基站配置的方式,使用载波1、载波2和载波3上发 送PDCCH或ePDCCH分别映射不同的CSI集合,这样UE可根据接收到PDCCH或ePDCCH的载波信息确定不同的CSI集合;
f2:CSI请求指示可采用将PDCCH或ePDCCH分组后的PDCCH或ePDCCH组的标识表示,具体在对PDCCH或ePDCCH分组后,而后使用不同的PDCCH组的标识或ePDCCH组的标识表示不同的CSI请求指示,进而映射到不同的CSI集合;
g2:CSI请求指示可采用PDCCH或ePDCCH可调度的载波的组的标识表示,由于不同的PDCCH或ePDCCH可调度不同的载波,这样可以以属于同一PDCCH或ePDCCH的调度载波的组表示表示不同的CSI请求指示,进而映射到不同的CSI集合中;
h2:CSI请求指示可采用PDCCH所属的波段的标识表示不同的CSI请求指示,进而可将属于不同波段的载波上的CSI归为不同的CSI集合与CSI请求指示映射;
i2:CSI请求指示可采用调度上行发送或下行发送的资源的数量、或时域位置、或频域位置来表示,用以表示不同的CSI请求指示,进而映射到不同的CSI集合。
j2:CSI请求指示可采用DCI在公共搜索空间还是UE搜索空间来表示,用以暗示不同的CSI请求指示,进而映射到不同的CSI集合。例如,如果UE在公共搜索空间接收的CSI的发送请求表示映射的所有载波的CQI。
当然,以上多种CSI请求指示的表示规则也可以采用任意两种或两种以上的规则组合来实现。
当采用预先配置的方式或者基站向UE进行网络配置的方式为UE配置了不同的CSI请求指示和不同的CSI集合类型具备的CSI集合之后,也可以采用预先配置的方式或者基站向UE进行网络配置的方式为UE配置CSI请求指示与CSI集合类型之间的映射关系。该映射关系可以是CSI请求指示与CSI集合类型之间一一映射,也可以是一对多映射、多对一映射或多对多映射等。
而后,基站便可使用不同的CSI请求指示触发非周期的CSI上报,UE便按照映射关系向基站反馈不同的CSI。
举例来说,以上述规则a1和规则e2组合,当基站CSI请求指示采用基站用于发送PDCCH的载波的载波标识表示,CSI集合类型为触发高层配置的第一个CSI集合上报,该第一个CSI集合对应的CSI为将载波按照载波标识分组后的同一个载波组的CSI时,可使得基站在不同的载波上发送PDCCH表示触发不同的载波及不同载波个数的CSI。
比如UE可支持32载波聚合时,基站在载波1上发送PDCCH触发UE上报非周期CSI的请求指示表示UE需要上报第一个CSI集合,也就是CSI集合类型为第一个CSI集合,该第一个CSI集合的为所有32个载波的CSI,在载波2上发送PDCCH触发UE上报非周期CSI的请求指示表示UE需要上报第二个CSI集合,也就是CSI集合类型为第二个CSI集合,该第二个CSI集合为标识为1~16这前16个载波的CSI,在载波3上发送PDCCH触发UE上报非周期CSI的请求指示表示UE需要上报第三个CSI集合,也就是CSI集合类型为第三个CSI集合,该第三个CSI集合为标识为17~32这后16个载波的CSI。针对这一举例,CSI请求指示与CSI集合类型的映射关系可以如表1所示。
表1
Figure PCTCN2015076371-appb-000001
其中,‘00’和‘01’的指示方式可与现有技术相同,分别表示不触发UE上报非周期CSI和触发UE上报上行载波的CSI,‘1’、 ‘2’、‘3’表示载波的标识,不同的载波标识与不同的CSI集合映射。
再举例来说,以上述规则b1和规则a2组合,对于大数量载波聚合例如32载波聚合来说,当CSI集合类型对应的CSI集合为将不同小区按照归属不同的物理上行链路控制信息PUCCH分组后,属于同一个PUCC组的小区的下行载波的CSI,和CSI请求指示采用至少3个比特来实现更多的CSI请求指示(CSI request field)映射到不同的CSI集合类型时,具体可通过增加DCI中的CSI request field的bit个数,比如从2个bit增加到3个bit,用以表示触发不同的PDCCH组中的载波上报CSI。例如011表示基站触发UE上报第一个CSI集合上报,该第一个CSI集合对应第一个PUCCH组中的载波,100表示基站触发UE上报第二个CSI集合上报,该第二个CSI集合对应第二个PUCCH组中的载波的CSI,101表示基站触发UE上报第三个CSI集合上报,该第三个CSI集合对应第三个PUCCH组中的载波的CSI上报等。
再举例来说,采用规则c1和规则h2组合,当CSI集合类型对应的CSI集合为将载波按照不同的波段进行分组后属于同一波段或同一波段组合的载波的CSI,CSI请求指示采用PDCCH所属的波段的标识表示不同的CSI请求指示时,如果CSI请求指示为某一波段的标识,表示基站触发UE上报该波段的载波的CSI上报。
本发明实施例提供了一种信道状态信息的上报方法,可用于大数量载波聚合,通过UE接收基站发送的控制信息,所述控制信息包括第一CSI请求指示,且该第一CSI请求指示的表示方式与现有技术不同,可包含3个bit或其它指示信息,所述UE根据所述CSI请求指示与所述CSI集合类型的映射关系获取与所述第一CSI请求指示对应的第一CSI集合类型,其中,所述CSI请求指示用于指示所述UE上报非周期CSI,这里的CSI集合类型对应的CSI集合可以有多种,例如按不同载波、不同波段、不同PUCCH分组后的CSI集合,而后UE向所述基站发送CSI测量报告,所述CSI测量报告包括与所述CSI请求指示对应的CSI集合,这样一来,与现有技术 采用2个bit表示的4种CSI请求指示与4种CQI集合映射相比,本发明技术方案采用多种CSI请求指示方式和多种类型的CSI集合,可增加CSI请求指示的数量和不同类型的CSI集合的数量,这样对于大数量的载波聚合来说,使得CSI的上报更加灵活。
例如对于32载波聚合来说,相比现有技术中采用4种CSI请求指示,前2种指示分别表示不触发UE上报非周期CQI和上报上行载波的CQI,后两种指示分别与第一个CQI集合映射和第二个CQI集合映射,第一个CQI集合和第二个CQI集合会包括过多的CQI,但是这会造成UE上行PUSCH承载负载过重,上行PUSCH覆盖减少,但是如果采用本发明技术方案中的3个bit来表示更多的CQI集合时,可使得CQI在多种集合中上报,基站根据所需触发UE上报不同的CSI集合,会使得上行PUSCH承载较为均衡;如果现有技术采用每个CQI集合包含较少的CQI,会使得基站不能获知到部分信道的即时状态,不能获取更优选的信道状态,但是本发明采用多种类型的CQI,基站会根据所需获知到更多的信道状态信息,以便使通信***更好的适应当前的信道条件,在多天线***中为高可靠性高速率的通信提供保障。
相应的,对于基站侧来说,本发明实施例还提供一种信道状态信息的接收方法。其中,相同的内容可以参照上述实施例中的描述,本实施例不再赘述。如图2所示,该方法包括:
