Description

传输信道状态信息的方法和设备 技术领域
本发明涉及通信领域,并且更具体地,涉及传输信道状态信息的方法和设备。
背景技术
长期演进(Long Term Evolution,简称为“LTE”)系统中采用共享信道的方式发送数据,同样码元信号在不同的频率资源上传输,它的衰落和干扰是不相同的,而且还在不断变化。对下行数据,为了使基站(Evolutional Node B,简称为“eNB”)选择合适的频率资源及让用户设备(User Equipment,简称为“UE”)能够较好的接收数据,eNB会在整个小区带宽上发送下行参考信号,然后UE按照上层指示测量全部或部分带宽的小区参考信号的信道质量状态,并通过信道状态信息(Channel State Information,简称为“CSI”)反馈给eNB。eNB根据UE所上报的CSI,选择合适的时频资源及调制编码方式(Modulation and Coding Scheme,简称为“MCS”)传输下行数据。
现在,第三代合作伙伴计划(3rd Generation Partnership Project,简称为“3GPP”)引入了辅助授权频段接入(License Assisted Access,简称为“LAA”)小区,与正常小区做载波聚合(Carrier Aggregation,简称为“CA”),但是LAA小区只能作为辅小区(Scell)。与正常小区不同的是,LAA小区所使用的是非授权的频段,任何人都可以使用这些频段进行通信,从而对LAA小区带来干扰,所以LAA小区的数据传输可靠度相对比较低。与此相对,使用授权频谱的小区,称为正常(Normal)小区,这些小区所使用的频率是经过官方授权的,所以干扰是可控的,数据传输相对可靠。同时3GPP规定,无论是eNB还是UE,它们在发送任何数据前都要先完成(Listen Before Talk,简称为“LBT”)过程,如果LBT成功,则数据正常发送;否则,数据不能发送。这个规定同样适用于下行参考信号。如果UE在测量下行参考信号时,由于eNB之前一直没有LBT成功,那么UE在CSI上报时,就会上报一个之前测量的值。
随着服务小区中的用户越来越多,但PUCCH资源又是有限的,如何实现非授权小区的CSI的有效上报是目前需要解决的重要问题。

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付出创造性劳动的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。
应理解,本发明实施例的技术方案可以应用于各种通信系统,例如:全球移动通讯(Global System of Mobile Communication,简称为“GSM”)系统、码分多址(Code Division Multiple Access,简称为“CDMA”)系统、宽带码分多址(Wideband Code Division Multiple Access,简称为“WCDMA”)系统、长期演进(Long Term Evolution,简称为“LTE”)系统、LTE频分双工(Frequency Division Duplex,简称为“FDD”)系统、LTE时分双工(Time Division Duplex,简称为“TDD”)、通用移动通信系统(Universal Mobile Telecommunication System,简称为“UMTS”)、以及未来的5G通信系统等。
应理解,在本发明实施例中,终端设备(Terminal Equipment)也可称之为用户设备、移动台(Mobile Station,简称为“MS”)、移动终端(Mobile Terminal)等,该用户设备可以经无线接入网(Radio Access Network,简称为“RAN”)与一个或多个核心网进行通信,例如,用户设备可以是移动电话(或称为“蜂窝”电话)、具有移动终端的计算机等,例如,可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置,以及未来5G网络中的终端设备或者未来演进的PLMN网络中的终端设备等。
还应理解,在本发明实施例中,网络设备可以是用于与用户设备进行通信的设备,该网络设备可以是GSM系统或CDMA中的基站(Base Transceiver Station,简称为“BTS”),也可以是WCDMA系统中的基站(NodeB,简称为“NB”),还可以是LTE系统中的演进型基站(Evolutional Node B,简称为“eNB”或“eNodeB”),或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络中的网络侧设备或未来演进的PLMN网络中的网络设备等。
在本发明实施例中,信道状态信息(Channel State Information,简称为“CSI”)主要包括信道质量指示(Channel Quality Indicator,简称为“CQI”)、预编码矩阵指示(Precoding Matrix Indicator,简称为“PMI”)、分集指示(Rank Indication,简称为“RI”)和预编码类型指示(Precoding Type Indicator,简 称为“PTI”)。本发明实施例中的CSI资源可以理解为CQI资源。
CSI上报的方式主要有两种:一种是通过物理上行共享信道(Physical Uplink Shared Channel,简称为“PUSCH”)上报非周期性CSI;一种是通过物理上行控制信道(Physical Uplink Shared Channel,简称为“PUCCH”)上报周期性CSI。对于非授权小区的非周期性CSI来说,UE如果在子帧N触发了非周期性CSI,那么需要等待到子帧N+k(K>=4)才能进行CSI上报。对于非授权小区的周期性CSI来说,eNB会预先给UE配置非授权小区周期性CSI资源,UE会在eNB所分配的CSI资源上进行周期性CSI上报。
图1是根据本发明实施例的传输信道状态信息CSI的方法的示意性流程图。该方法可以由终端设备执行,该方法应用于非授权小区。如图1所示,该方法100包括:
S110,第一设备确定非授权小区的CSI;
S120,该第一设备在第一传输资源上向第二设备发送该非授权小区的CSI,其中,该第一传输资源包括该第二设备为服务小区配置的第二传输资源,该服务小区不包括该非授权小区。
具体来说,第一设备确定非授权小区的CSI,在非授权小区可用时在第一传输资源上向第二设备发送该非授权小区的CSI,其中,该第一传输资源包括该第二设备为不包括该非授权小区的服务小区配置的第二传输资源。
需要说明的是,在本发明实施例中,第一设备为终端设备或称为用户设备,第二设备为网络设备或设备与设备通信(Device-to-Device,简称为“D2D”)通信中的终端设备。授权小区也可以称为正常小区(Normal Cell)可以为现有LTE系统中的LTE小区,非授权小区可以为授权辅助接入小区(License Assisted Access,简称为“LAA”)小区(LAA Cell),和/或Standalone LAA小区。
在本发明实施例中,在非授权小区被激活时,可以认为该非授权小区可用,在网络设备或者进行D2D通信的终端设备获取到非授权小区的频率资源时也可以认为该非授权小区可用。终端设备可以通过接收非授权小区的数据或信令或信号获知非授权小区可用,或,终端设备可以接收网络设备或者进行D2D通信的终端设备发送的指示信息或信号获知非授权小区可用。
因此,根据本发明实施例的传输信道状态信息的方法,第一设备可以在服务小区的传输资源上向第二设备上报非授权小区的信道状态信息,该服务 小区不包括该非授权小区。由此,即使在服务小区中的用户较多时,也能实现非授权小区的传输信道状态信息的快速甚至密集的上报,提升下行传输效率。
可选地,在S110中,该第一传输资源中还包括该第二设备为该非授权小区配置的用于周期性上报CSI的传输资源,也就是说,本发明实施例中的非授权小区可以同时通过自身的传输资源和其他服务小区上配置的传输资源进行CSI的上报。换句话说,第一设备可以使用自己其他服务小区(包括Normal Cell和非授权小区)的传输资源来传输非授权小区的CSI,也可以使用其他设备的服务小区(包括Normal Cell和非授权小区)的传输资源来传输非授权小区的CSI。由此,在其他服务小区的传输资源比较密集或者非授权小区可以用多个其他服务小区上配置的传输资源时,能够实现非授权小区的CSI的快速甚至密集的上报。
在本发明实施例中,可选地,第一设备可以与第二设备事先约定,只要是在非授权小区可用的时间段内存在能够用于传输信道状态信息的传输资源,第一设备就可以在这部分传输资源上上报可用非授权小区的信道状态信息,并且上报过程中采用的上报方式,例如是采用全带宽CQI上报还是子带宽CQI上报,均可以事先进行约定。
进一步地,该第一设备可以接收该第二设备发送的资源配置信息;相应地,第一设备根据接收到的资源配置信息,确定该第一传输资源。也就是说,第二设备可以给第一设备配置具体可用的传输资源,以方便该第一设备在配置的传输资源上进行CSI的上报。
需要说明的是,在第一设备使用其他设备的传输资源来传输非授权小区的CSI时,第一设备需要接收该第二设备发送的无线资源控制(Radio Resource Control,简称为“RRC”)重配置消息,该RRC重配置消息包括该资源配置信息。
在本发明实施例中,第二设备将其他设备的传输资源配置给第一设备作为上报CSI的传输资源,可以按照图2所示的方法进行,图2中仅以终端设备与网络设备进行通信,终端设备需要上报CQI为例进行描述,图2中的终端设备A可对应本发明实施例中的第一设备,基站eNB可对应本发明实施例中的第二设备,终端设备B可对应本发明实施例中的其他设备。如图2所示,该方法200包括:
S201,基站eNB向终端设备A发送RRC重配置消息1,同时向终端设备B发送RRC重配置消息2;
S202,基站接收终端设备A发送的RRC重配置完成消息和终端设备B发送的RRC重配置完成消息;
S203,基站在非授权小区向终端设备A发送下行数据;
具体地,完成相关配置后,非授权小区就可以向终端设备A发送数据。
S204,基站接收终端设备A发送的非授权小区的CQI;
具体地,完成相关配置后,终端设备A可以向基站进行非授权小区的CQI的上报。
应理解,如果需要为终端设备配置时间窗口,终端设备A和终端设备B需配置相同的时间窗口。并且如果终端设备A的非授权小区可用,那么相应的终端设备B的周期性CSI资源就不能传输自己的CQI,而是让终端设备A上报非授权小区的CQI。
并且,可选地,终端设备B可以通过物理层消息或媒体接入控制(Media Access Control,简称为“MAC”)消息或RRC消息获知终端设备A的非授权小区可用。终端设备B还可以自行判断终端设备A的非授权小区可用,例如,终端设备B可以通过测量接收的信号强度指示(Received Signal Strength Indication,简称为“RSSI”)值,如果测量的RSSI值大于一定门限,则认为终端设备A的非授权小区可用,否则认为终端设备A的非授权小区不可用。
可选地,可以按照下面描述的方式对终端设备A和终端设备B进行具体参数的配置:
Figure PCTCN2015090569-appb-000001
Figure PCTCN2015090569-appb-000002
其中,cqi-pmi-ConfigIndex指示了非授权小区周期性CSI资源的时频资源位置,periodicityFactor为H,通过cqi-pmi-ConfigIndex查询现有通信标准中的表7.2.2-1A,即可以获取Npd和NOFFSET,CQI
表7.2.2-1A
Figure PCTCN2015090569-appb-000003
进一步地,如果终端设备B采用的传输模式是TM10,则可以按照下面的方式为终端设备A配置终端设备B的Normal Cell的一个或多个CSI进程的周期性CSI资源:
Figure PCTCN2015090569-appb-000004
Figure PCTCN2015090569-appb-000005
其中,cqi-pmi-ConfigIndex指示了非授权小区周期性CSI资源的时频资源位置,其具体取值可以查看现有通信标准中表7.2.2-1A。
因此,本发明实施例的传输信道状态信息的方法,设备可以通过其他设备上配置的传输资源发送非授权小区的CSI。由此,可以无需给该设备的非授权小区配置CSI传输资源,可以节省传输资源,并能够实现非授权小区的信道状态信息的快速甚至密集的上报,提高下行传输效率。
在本发明实施例中,可选地,如图3所示,该方法100还包括:
S130,该第一设备确定时间窗口;
S140,该第一设备根据该时间窗口,确定该第一传输资源;
其中,该第一传输资源在时域上对应的时间段在该预设时间窗口对应的时间段内。
也就是说,可以给第一设备配置一个窗口开关,在窗口开放期间,如果非授权小区可用,则窗口开放期间的传输资源用于传输非授权小区的CSI。如果非授权小区不可用,则继续传输原来服务小区的CSI。
并且,当在时间窗口开放期间,有多个能够用于传输CSI的资源时,第二设备还可以通过资源指示信息指示具体哪个/些资源可以配置给第一设备用于传输非授权小区的CSI。
可选地,该第一设备接收到的该资源配置信息中可以包括时间窗口信息,第一设备可以根据该时间窗口信息,确定该时间窗口的子帧偏置和/或时间长度和/或周期。也就是说,第一设备可以根据接收到的时间窗口信息确定时间窗口的打开时机、时间窗口打开一次持续的时间以及时间窗口重复打开的周期等。
下面以基站eNB与终端设备UE进行通信为例进行说明,如图4所示,eNB根据业务需求给一个UE配置了两个辅小区SCell和一个主小区PCell,其中,PCell是Normal Cell,两个SCell分别是Normal Cell和LAA Cell,并且为两个Normal Cell都分配了不同的周期性CSI资源。同时还给UE配置了一个CQI窗口持续时间(CQI-LAAonDurationTimer)定时器,在CQI-LAAonDurationTimer定时器运行期间,如果LAA Cell可用,如LAA Cell对应的加粗线部分,那么UE通过这两个Normal Cell的CSI资源中对应的时间段在CQI-LAAonDurationTimer定时器运行期间的这部分CSI资源上传输LAA Cell的周期性CQI,如CSI资源3、4、5和6,CSI资源10、11和12。eNB为UE配置时间窗口时,可以按照下面的方式进行配置:

其中,ScellIndex表示LAA Cell的序号;cqi-LAAWindowInfo表示窗口开关,Period表示窗口开关的周期;Offset表示窗口开关的子帧偏置;CQI-LAAonDurationTimer表示窗口开的时间长度;widebandCQI表示全带宽;subbandCQI表示子带宽,k表示轮询次数。
可选的,窗口开关打开可通过以下公式得出:

其中,nf为SFN系统帧号,ns为一个子帧号,NOFFSET,LAAWindow为窗口开关的子帧偏置Offset,Nperiod为窗口开关的周期Period。窗口打开时,启动或重启CQI-LAAonDurationTimer定时器,定时器超时则窗口开关关闭。
如果eNB给一个UE配置多个非授权小区,不同非授权小区的时间窗口可以一样,也可以不一样,那么这些非授权小区所使用的其他服务小区的周期性CSI资源,同样可以是互不不同的,也可以是完全相同的或部分相同的。
进而,如图5所示,S120包括:
S121,接收优先级信息;
S122,根据该优先级信息,确定该非授权小区的优先级;
S123,在该非授权小区的优先级为最高优先级时,在该第一传输资源上发送该非授权小区的CSI。
也就是说,在多个非授权小区占用相同的传输资源时,可以优先发送优先级最高的那个非授权小区的CSI,应理解,也可以不发送优先级最高的那个非授权小区的CSI,而发送次高优先级的非授权小区的CSI或者其他优先级的非授权小区。并且非授权小区的优先级由第二设备配置,例如,可以根据非授权小区的标识ID来区分非授权小区的优先级,同一个非授权小区相对于不同的设备优先级可能各不相同。
可选地,在该第一设备发送多个非授权小区的CSI时,该第一传输资源与该第一设备发送该多个非授权小区中其他非授权小区的CSI的传输资源不同,例如,可以给不同的非授权小区配置不同的时间窗口,任意两个时间窗口没有交叠,或者,第二设备可以通过资源配置保证不同非授权小区用于上报CSI的传输资源不冲突,比如,非授权小区1和非授权小区2都抢占同一个Normal Cell的CSI资源,可以配置非授权小区1占用奇数子帧的CSI资源,非授权小区2占用偶数子帧的CSI资源,或者,配置非授权小区1占用偶数子帧的CSI资源,非授权小区2占用奇数子帧的CSI资源,但本发明并不限于此。
在本发明实施例中,可选地,如图6所示,该方法100还包括:
S150,该第一设备确定CSI上报方式;
其中,S120具体为:根据该CSI上报方式,在该第一传输资源上发送该非授权小区的CSI。
可选地,第一设备可以根据通信标准规定的CSI上报方式进行非授权小区的CSI的上报;第一设备还可以接收第二设备发送的CSI上报方式指示信息,根据该CSI上报方式指示信息确定该CSI上报方式。
可选地,该CSI上报方式指示信息可以采用与现有技术相同的指示方式,并且当该CSI上报方式指示信息指示第一设备采用全带宽CSI上报或子带宽CSI上报时,第一设备可以采用现有技术中全带宽CSI上报和子带宽CSI上报的具体实现方式进行CSI的上报。
举例来说,一个非授权小区使用一个或多个Normal Cell的周期性CSI 资源传输非授权小区的CQI,它们的相关配置,如全带宽和子带宽的轮询次数,可以相同也可以不同,下面以eNB与UE进行通信为例进行说明,具体可以体现在以下几个方面:
(1)如果Normal Cell只配置全带宽CQI上报,那么非授权小区在Normal Cell的CSI资源上同样只上报全带宽CQI。
(2)如果Normal Cell只配置全带宽CQI上报,而非授权小区在Normal Cell的CSI资源上上报全带宽CQI和子带宽CQI,那么eNB通过RRC消息把相应的消息内容,如非授权小区的全带宽CQI周期(Period)和偏置(Offset),子带宽CQI的轮询次数等通知UE。其中,子带宽的轮询次数可以理解为:全带宽上报周期与子带宽上报周期的比值减去1得到的结果除以子带宽组数的向上取整。该子带宽组数等于下行带宽资源块(Resource Block,简称为“RB”)数与子带数的比值与子带所占的RB数的比值。Offset可以为时隙偏置或子帧偏置,具体指CQI上报的具体时隙或子帧位置。
(3)如果Normal Cell配置了全带宽CQI和子带宽CQI上报,那么非授权小区采用相同配置,即非授权小区的全带宽CQI周期和偏置,子带宽CQI的轮询次数等都与Normal Cell的配置一样。
(4)如果Normal Cell配置了全带宽CQI和子带宽CQI上报,那么非授权小区采用不同的配置,即非授权小区的全带宽CQI周期和偏置,子带宽CQI的轮询次数等,具体的配置由eNB通过RRC消息通知UE。
在本发明实施例中,可选地,该第二传输资源对应的CSI进程为该服务小区中一个服务小区的部分CSI进程;或者该第二传输资源对应的CSI进程为该服务小区中多个服务小区的部分CSI进程。
具体来说,针对传输模式10,每一个服务小区可能为UE配置多种上报模式,它们对应不同的CSI进程,不同的进程ID分配不同周期和偏置的周期性CSI资源。为此,eNB可以将一个服务小区的部分CSI资源配置给非授权小区,由此可以在传输非授权小区的CSI时,不影响该服务小区的CSI的传输,eNB也可以将不同Normal Cell的部分CSI进程对应的传输资源配置给非授权小区。如果在这些资源上非授权小区可用,那么就上报非授权小区的CSI;否则,上报原来服务小区的CSI。
举例来说,如图7所示,eNB根据业务需求给UE配置了一个SCell和一个PCell,其中PCell是Normal Cell,SCell是LAA Cell。并且为Normal Cell 配置了两种不同CSI进程的周期性CSI资源,然后配置其中的一个或多个CSI进程标识(CQI-LAAExtToLAAId)的周期性CSI资源作为LAA Cell的周期性CSI资源,如CSI资源1、3、5、7等,和/或,CSI资源2、4、6、8等。如果LAA Cell可用,即图中粗线部分,则CSI资源就用来传输LAA Cell的周期性CSI,即CSI资源3和4,CSI资源10和12。
在本发明实施例中,针对传输模式10,可以按照以下方式给LAA Cell配置传输资源:
Figure PCTCN2015090569-appb-000009
Figure PCTCN2015090569-appb-000010
在本发明实施例中,可选地,一个非授权小区使用另一个或多个Normal Cell的不同CSI进程的周期性CSI资源传输非授权小区的CQI时,它们的相关配置,如全带宽和子带宽的轮询次数,可以相同也可以不同。这种相同可以体现为:
(1)如果Normal Cell只配置全带宽CQI上报,那么非授权小区在Normal Cell的CSI资源上同样只上报全带宽CQI。
(2)如果Normal Cell只配置全带宽CQI上报,而非授权小区在Normal Cell的CSI资源上上报全带宽CQI和子带宽CQI,那么eNB通过RRC消息把相应的消息内容,如非授权小区的全带宽CQI周期和偏置,子带宽CQI的轮询次数等,通知UE。
(3)如果Normal Cell配置了全带宽CQI和子带宽CQI上报,那么非授权小区采用相同配置,即非授权小区的全带宽CQI周期和偏置,子带宽CQI的轮询次数等都与Normal Cell的配置一样。
(4)如果Normal Cell配置了全带宽CQI和子带宽CQI上报,那么非授权小区采用不同的配置,即非授权小区的全带宽CQI周期和偏置,子带宽CQI的轮询次数等,具体的配置由eNB通过RRC消息通知UE。
在本发明实施例中,可选地,非授权小区的非周期性CSI上报可以通过周期性CSI资源进行上报,这些周期性CSI资源可选的可以为本发明实施例中的第二传输资源。现有技术中在采用非周期性CSI上报时,如果UE在子帧N触发了非周期性CSI,那么需要等到子帧N+k(k>=4)才能进行CSI的上报,这样会影响eNB下行数据传输。而如果采用本发明实施例的方法,UE在子帧N触发了非授权小区的非周期性CSI后,如果在编号小于N+k的子帧中存在其他服务小区的CSI传输资源,UE可以在该子帧上进行CSI的上报,而不必等到子帧N+k时进行上报,由此,在进行非授权小区的非周期性CSI上报时,能够降低传输时延。
因此,根据本发明实施例的传输信道状态信息的方法,第一设备可以在服务小区的传输资源上向第二设备上报非授权小区的信道状态信息,该服务小区不包括该非授权小区。由此,即使在服务小区中的用户较多时,也能实现非授权小区的信道状态信息的快速甚至密集的上报,提升下行传输效率。
以上结合图1至图7从第一设备侧详细描述了根据本发明实施例的传输信道状态信息的方法,下面将结合图8和图9从第二设备侧详细描述根据本发明实施例的传输信道状态信息的方法,应理解,第一设备侧描述的第二设备与第一设备的交互及相关特性、功能等与第二设备侧的描述相应,为了简洁,适当省略重复的描述。
图8是根据本发明另一实施例的传输信道状态信息的方法的示意性流程图,该方法应用于非授权小区,如图8所示,该方法300包括:
S310,第二设备接收第一设备在第一传输资源上发送的非授权小区的CSI,其中,该第一传输资源包括该第二设备为服务小区配置的第二传输资源,该服务小区不包括该非授权小区。
S320,该第二设备根据该CSI,向该第一设备发送数据。
具体来说,第二设备接收第一设备在包括该第二设备为服务小区配置的第二传输资源的第一传输资源上发送的非授权小区的CSI,该服务小区不包括该非授权小区,并根据该CSI向该第一设备发送数据。
需要说明的是,在本发明实施例中,第一设备为终端设备或称为用户设备,第二设备为网络设备或设备与设备通信(Device-to-Device,简称为“D2D”)通信中的终端设备。授权小区也可以称为正常小区(Normal Cell)可以为现有LTE系统中的LTE小区,非授权小区可以为授权辅助接入小区(License Assisted Access,简称为“LAA”)小区(LAA Cell),也可以为Standalone LAA小区。
在本发明实施例中,在非授权小区被激活时,可以认为该非授权小区可用,在网络设备或者进行D2D通信的终端设备获取到非授权小区的频率资源时也可以认为该非授权小区可用。终端设备可以通过接收非授权小区的数据或信令或信号获知非授权小区可用,或终端设备可以接收网络设备或者进行D2D通信的终端设备发送的指示信息或信号获知非授权小区可用。
因此,根据本发明实施例的传输信道状态信息的方法,第二设备可以接收第一设备在服务小区的传输资源上上报的非授权小区的信道状态信息,该服务小区不包括该非授权小区。由此,即使在服务小区中的用户较多时,也能实现非授权小区的信道状态信息的快速甚至密集的上报,提升下行传输效率。
在本发明实施例中,可选地,第一设备可以与第二设备事先约定,只要 是在非授权小区可用的时间段内存在能够用于传输信道状态信息的传输资源,第一设备就可以在这部分传输资源上上报可用非授权小区的信道状态信息,并且上报过程中采用的上报方式,例如是采用全带宽CQI上报还是子带宽CQI上报,均可以事先进行约定。
在本发明实施例中,可选地,该第二设备向该第一设备发送资源配置信息,以便于该第一设备根据该资源配置信息确定该第一传输资源。也就是说,第二设备可以给第一设备配置具体可用的传输资源,以方便该第一设备在配置的传输资源上进行CSI的上报。
在本发明实施例中,可选地,该资源配置信息还包括时间窗口信息,以便于该第一设备根据该时间窗口信息确定时间窗口,并根据该时间窗口确定该第一传输资源。
在本发明实施例中,可选地,该窗口信息包括下列信息中的至少一种:该时间窗口的子帧偏置、时间长度和周期。
在本发明实施例中,可选地,该第二设备可以向该第一设备发送CSI上报方式指示信息,以便于该第一设备根据该CSI上报方式指示信息确定该CSI上报方式。
可选地,如图9所示,该方法还包括:
S330,该第二设备向该第一设备发送优先级信息,以便于该第一设备根据该优先级信息确定该非授权小区的优先级;
相应地,S310为:该第二设备接收该第一设备确定该非授权小区的优先级为最高优先级时,在该第一传输资源上发送该非授权小区的CSI。
在本发明实施例中,可选地,该第一设备在发送多个非授权小区的CSI时,该第一传输资源与该第一设备用于发送多个非授权小区中其它非授权小区的传输资源不同。
可选地,在S310中,该第二传输资源对应的CSI进程为该服务小区中一个服务小区的部分CSI进程。
可选地,在S310中,该第二传输资源对应的CSI进程为该服务小区中多个服务小区的部分CSI进程。
可选地,在S310中,该服务小区为除该第一设备之外的其他设备的服务小区。
在本发明实施例中,可选地,在服务小区为除该第一设备之外的其他设 备的服务小区时,该第二设备向该第一设备发送无线资源控制RRC重配置消息,该RRC重配置消息包括该资源配置信息。
可选地,在S310中,该服务小区为该第一设备的服务小区。
在本发明实施例中,可选地,在该服务小区为该第一设备的服务小区时,该第二设备接收该第一设备在确定该非授权小区不可用时,在该第二传输资源上发送的该服务小区的CSI。
可选地,在S310中,该第一传输资源还包括该第二设备为该非授权小区配置的用于周期性上报CSI的传输资源。
也就是说,本发明实施例中的非授权小区可以同时通过自身的传输资源和其他服务小区上配置的传输资源进行CSI的上报。换句话说,第一设备可以使用自己其他服务小区(包括Normal Cell和非授权小区)的传输资源来传输非授权小区的CSI,也可以使用其他设备的服务小区(包括Normal Cell和非授权小区)的传输资源来传输非授权小区的CSI。由此,在其他服务小区的传输资源比较密集或者非授权小区可以用多个其他服务小区上配置的传输资源时,能够实现非授权小区的CSI的快速甚至密集的上报。
在本发明实施例中,可选地,第一设备的非授权小区的非周期性CSI上报可以通过周期性CSI资源进行上报,这些周期性CSI资源可选的可以为本发明实施例中的第二传输资源。现有技术中在采用非周期性CSI上报时,如果UE在子帧N触发了非周期性CSI,那么需要等到子帧N+k(k>=4)才能进行CSI的上报,这样会影响eNB下行数据传输。而如果采用本发明实施例的方法,UE在子帧N触发了非授权小区的非周期性CSI后,如果在编号小于N+k的子帧中存在其他服务小区的CSI传输资源,UE可以在该子帧上进行CSI的上报,而不必等到子帧N+k时进行上报,由此,在进行非授权小区的非周期性CSI上报时,能够降低传输时延。
因此,根据本发明实施例的传输信道状态信息的方法,第二设备可以接收第一设备在服务小区的传输资源上上报的非授权小区的信道状态信息,该服务小区不包括该非授权小区。由此,即使在服务小区中的用户较多时,也能实现非授权小区的信道状态信息的快速甚至密集的上报,提升下行传输效率。

因此,本发明实施例的传输信道状态信息的设备可以在服务小区的传输资源上向第二设备上报非授权小区的信道状态信息,该服务小区不包括该非授权小区,由此,即使在服务小区中的用户较多时,也能实现非授权小区的信道状态信息的快速甚至密集的上报,提升下行传输效率。

因此,本发明实施例的传输信道状态信息的设备可以在服务小区的传输资源上向第二设备上报非授权小区的信道状态信息,该服务小区不包括该非授权小区,由此,即使在服务小区中的用户较多时,也能实现非授权小区的信道状态信息的快速甚至密集的上报,提升下行传输效率。
