Description

信道状态信息的上报方法、装置、终端及存储介质 技术领域
本申请涉及无线通信领域,特别涉及一种信道状态信息的上报方法、装置、终端及存储介质。
背景技术
在5G新空口(New Radio,NR)中,网络设备可以为终端设备配置非连续接收(Discontinuous Reception,DRX)功能。终端设备在DRX活跃时间(Active Time),可以进行信道状态信息(Channel State Information,CSI)的上报,使得网络设备能够获得下行传输的信道状况和干扰情况。
在上报CSI之前,终端设备需要通过CSI参考信号(CSI-RS)对下行传输信道进行测量。为了增强DRX,NR Rel-16讨论通过:对于一个媒体接入控制(Media Access Control,MAC)实体,由配置一个DRX组(group)变更为配置两个DRX组。每个DRX组有其对应的激活期(Active Time),每个DRX组可以对应一个或者多个载波(carrier)。
针对上述两个DRX组的配置,上报CSI的载波和被测量的载波可能会位于不同的DRX组,两个载波是否处于激活期的情况也不同。对于终端设备是否需要上报CSI的问题,相关技术尚未提供较好的解决方案。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚,下面将结合附图对本申请实施方式作进一步地详细描述。
首先,对本申请实施例中涉及的名词进行简单介绍:
信道状态信息(Channel State Information,CSI):是通信链路的一种信道属性。它描述了信号在每条传输路径上的衰弱因子,即信道增益矩阵H中每个元素的值,如信号散射(Scattering),环境衰弱(fading,multipath fading or shadowing fading),距离衰减(power decay of distance)等信息。CSI可以使通信系统适应当前的信道条件,在多天线系统中为高可靠性高速率的通信提供了保障。
非连续接收(Discontinuous Reception,DRX):DRX可以让终端周期性的在某些时候进入休眠期,不去监听物理下行控制信道(Physical Downlink Control Channel,PDCCH)调度信息(或称PDCCH子帧)。而在终端需要监听PDCCH调度信息的时候,则从休眠期中唤醒(wake up),这样就可以使终端达到省电的目的。
DRX的基本机制是为处于无线资源控制连接态(Radio Resource Control_CONNECTED,RRC_CONNECTED)态的终端配置一个DRX周期(DRX cycle)。DRX周期由“激活态(On Duration)”和“休眠态(Opportunity  for DRX)”组成:在“激活态”的时间内,终端监听并接收PDCCH调度信息;在“休眠态”时间内,终端不接收下行信道的数据以节省功耗。从图1可以看出,在时域上,时间被划分成一个个连续的DRX周期(Cycle)。当终端在“激活态”期间收到一个调度消息时,终端会启动一个DRX的非活跃态定时器(DRX-Inactivity Timer)并在该期间的每一个子帧监听PDCCH调度信息;如果DRX-Inactivity Timer正在运行,那么即便原本配置的On Duration时间已经结束,终端仍然需要继续监听下行的PDCCH子帧,直到DRX-Inactivity Timer的超时。
一个DRX周期等于终端的唤醒时间和休眠时间的总和,唤醒时间即为一个周期内的激活态的时长,休眠时间即为一个周期内的休眠期的时长。在通信系统里,系统可以根据不同的业务场景,终端分别配置有短周期(short cycle),或者长周期(long cycle),如图2所示。长周期的休眠时期比短周期的休眠时期长,或者说,长周期的休眠时长占比比短周期的休眠时长占比大。在DRX非活跃态定时器超时之后,若终端配置有短周期,则终端进入短周期,否则进入长周期。对于配置了短周期的场景,DRX非活跃态定时器超时后,终端进入短周期的行为通常是因为网络在发送一个大数据包后又发送了一系列小数据包,比如,web浏览等非实时业务,下载一个主页面后紧跟着下载一系列小的对象。故对于短周期可以认为是一种高活跃状态。
图3示出了本申请一个示例性实施例提供的通信系统的框图,该通信系统可以包括:接入网12和终端设备14。
接入网12中包括若干个网络设备120。网络设备120可以是基站,所述基站是一种部署在接入网中用以为终端提供无线通信功能的装置。基站可以包括各种形式的宏基站,微基站,中继站,接入点等等。在采用不同的无线接入技术的系统中,具备基站功能的设备的名称可能会有所不同,例如在LTE系统中,称为eNodeB或者eNB;在5G NR-U系统中,称为gNodeB或者gNB。随着通信技术的演进,“基站”这一描述可能会变化。为方便本申请实施例中,上述为终端设备14提供无线通信功能的装置统称为网络设备。
终端设备14可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备,以及各种形式的用户设备,移动台(Mobile Station,MS),终端(terminal device)等等。为方便描述,上面提到的设备统称为终端。网络设备120与终端设备14之间通过某种空 口技术互相通信,例如Uu接口。
本申请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,GSM)系统、码分多址(Code Division Multiple Access,CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)系统、通用分组无线业务(General Packet Radio Service,GPRS)、长期演进(Long Term Evolution,LTE)系统、LTE频分双工(Frequency Division Duplex,FDD)系统、LTE时分双工(Time Division Duplex,TDD)系统、先进的长期演进(Advanced long Term Evolution,LTE-A)系统、新无线(New Radio,NR)系统、NR系统的演进系统、非授权频段上的LTE(LTE-based access to Unlicensed spectrum,LTE-U)系统、NR-U系统、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access,WiMAX)通信系统、无线局域网(Wireless Local Area Networks,WLAN)、无线保真(Wireless Fidelity,WiFi)、下一代通信系统或其他通信系统等。
通常来说,传统的通信系统支持的连接数有限,也易于实现,然而,随着通信技术的发展,移动通信系统将不仅支持传统的通信,还将支持例如,设备到设备(Device to Device,D2D)通信,机器到机器(Machine to Machine,M2M)通信,机器类型通信(Machine Type Communication,MTC),车辆间(Vehicle to Vehicle,V2V)通信以及车联网(Vehicle to Everything,V2X)系统等。本申请实施例也可以应用于这些通信系统。
图4示出了本申请一个示例性实施例提供的信道状态信息的上报方法的流程图,该方法可以应用于如图3所示的终端设备中。该方法包括:
步骤410,根据测量的CSI参考信号是否位于第一DRX组的激活期内,确定是否上报CSI;
网络设备可以为终端设备配置DRX功能,使终端设备非连续地监听PDCCH,以达到节省终端设备电量的目的。
在DRX模式下,网络设备会为终端设备配置一个DRX周期,一个DRX周期包括激活期(Active Time)和非激活期,在激活期内,终端设备监听并接收PDCCH,在非激活期内,终端设备进入休眠状态,不去监听PDCCH以减少终端设备的功耗。
在载波聚合(Carrier Aggregation,CA)场景下,终端设备可以配置有至少两个DRX组,即,对于一个MAC实体,配置有至少两个DRX组。第一DRX组是至少两个DRX组中的一个。
可选地,CA场景下,存在一个主小区(Primary Cell,PCell)和至少一个辅小区(Secondary Cell,SCell),DRX组a默认配置给所有的服务小区。网络设备可以配置SCell中的SCell 2、SCell3、SCell4DRX组b,在这种情况下,SCell2、SCell3、SCell4的DRX参数采用DRX组b的参数,其他服务小区如PCell和SCell1的DRX参数采用DRX组a的参数。示例性的,终端设备在SCell 2、SCell3、SCell4中的一个服务小区上测量CSI时,即CSI参考信号配置在SCell2、SCell3、SCell4中的一个服务小区上时,终端设备将采用DRX组b对应的DRX参数进行CSI测量,即第一DRX组是DRX组b。示例性的,终端设备在PCell或SCell1上测量CSI时,即CSI参考信号配置在PCell或SCell1上时,终端设备将采用DRX组a对应的DRX参数进行CSI测量,即第一DRX组是DRX组a。上述PCell和SCell1-SCell4均为终端设备所配置的服务小区。
在上述示例中,终端设备上报CSI的物理资源可以采用DRX组a关联的服务小区(serving cell),也可以采用DRX组b关联的辅小区(SCell)。本实施例针对的情况是:终端设备上报CSI采用的第二DRX组关联的SCell,与测量CSI的服务小区对应的第一DRX组是不同的DRX组。即,本实施例针对的情况为:第一DRX组是DRX组b,第二DRX是DRX组a;或,第一DRX组是DRX组a,第二DRX是DRX组b。
终端设备使用第一DRX组对应的DRX参数,在第一DRX组的时域位置上进行CSI测量。示例性的,CSI参考信号配置在一个服务小区内,该服务小区采用第一DRX组对应的DRX参数。
可选地,终端设备能够从网络设备处接收用于估计信道的CSI参考信号,计算CSI,并将CSI上报至网络设备。终端设备测量CSI可以包括:终端设备接收CSI参考信号,以及终端设备基于接收到的CSI参考信号来计算CSI。
需要说明的是,终端设备可以是在第一DRX组的激活期内进行CSI测量,也可以在第一DRX组的非激活期内进行CSI测量。终端设备可以根据进行CSI测量的时域位置是位于第一DRX组的激活期内,还是非激活期内,判断是否需要上报CSI。
可选地,终端设备在DRX模式下的激活期包括如下几种情况:
一、非连续接收的持续时间定时器DRX-onDurationTimer,非连续接收的非活跃态定时器DRX-InactivityTimer,非连续接收的下行链路重传定时器DRX-RetransmissionTimerDL,非连续接收的上行链路重传定时器DRX-RetransmissionTimerUL以及随机接入-竞争解决定时器RA-ContentionResolutionTimer这5个定时器中的任何一个定时器正在运行。
二、终端设备在物理上行控制信道(Physical Uplink Control Channel,PUCCH)上发送了调度请求(Scheduling Request,SR),且SR当前处于待定(pending)状态。
三、在基于竞争的随机接入过程中,终端设备在成功接收到随机接入响应后还没有接收到小区无线网络临时标识(Cell-Radio Network Temporary Identifier,C-RNTI)加扰的PDCCH指示的一次初始传输。
可选地,关于上述DRX-onDurationTimer的启动,终端设备会根据当前是处于短DRX周期(short DRX cycle)还是长DRX周期(long DRX cycle),来决定启动该定时器的时间。
情况一:当前处于短DRX周期。
当前子帧满足[(SFN×10)+subframe number]modulo(DRX-ShortCycle)=(DRX-StartOffset)modulo(DRX-ShortCycle),则终端设备在当前子帧开始的DRX-SlotOffset个时隙(slot)之后的时刻启动drx-onDurationTimer。
其中,SFN是系统帧号(System Frame Number),subframe number是当前子帧的子帧号;DRX-ShortCycle是短DRX周期;DRX-StartOffset是DRX周期开始的子帧偏移。
情况二:当前处于长DRX周期。
当前子帧满足[(SFN×10)+subframe number]modulo(DRX-LongCycle)=DRX-StartOffset,则终端设备在当前子帧开始的DRX-SlotOffset个时隙(slot)之后的时刻启动drx-onDurationTimer。
其中,SFN是系统帧号(System Frame Number),subframe number是当前子帧的子帧号;DRX--Long Cycle是长DRX周期;DRX-StartOffset是DRX周期开始的子帧偏移。
CSI指的是在无线通信领域中,通信链路的信道属性。网络设备可以基于从终端设备反馈的CSI来发送数据信号。CSI可以包括一条或若干条信息,如秩指示符(Rank Indicator,RI)、预编码矩阵指示符(Pre-coding Matrix Indicator,PMI)、 信道质量信息(Channel Quality Indicator,CQI)、CSI参考信号资源指示符(CSI-RS Resource Indicator,CRI)等,本申请对CSI包括的信息不进行限制。
示例性的,CSI包括CQI。CQI被提供给网络设备,以便当网络设备发送数据时,提供与将应用哪种调制和编码方案(Modulation and Coding Scheme,MCS)有关的指导信息,以便于链路自适应。在网络设备与终端设备之间存在高无线质量的通信的情况下,终端设备可以反馈高CQI值,并且网络设备可以通过应用相对高的调制阶数和低信道编码率来发送数据。在相反的情况下,终端设备可以反馈低CQI值,并且网络设备可以通过应用相对低的调制阶数和高信道编码率来发送数据。
示例性的,CSI包括PMI。PMI被提供给网络设备,以便在网络设备已安装了多个天线时,提供与将应用哪种多入多出(Multiple-Input Multiple-Output,MIMO)预编码方案有关的指导。
步骤420,在确定上报CSI的情况下,在第二DRX组的时域位置上,上报CSI。
其中,第二DRX组是至少两个DRX组中的另一个。终端设备配置有至少两个DRX组,测量CSI的载波位于第一DRX组,预备用来上报CSI的载波位于第二DRX组。
可选地,CA场景下,DRX组a默认配置给所有的服务小区。网络设备可以配置SCell中的SCell 2、SCell3、SCell4DRX组b,在这种情况下,SCell2、SCell3、SCell4的DRX参数采用DRX组b的参数,其他服务小区如PCell和SCell1的DRX参数采用DRX组a的参数。示例性的,终端设备在SCell 2、SCell3、SCell4中的一个服务小区上上报CSI时,终端设备将采用DRX组b对应的DRX参数进行上报,即第二DRX组是DRX组b。示例性的,终端设备在PCell或SCell1上上报CSI时,终端设备将采用DRX组a对应的DRX参数进行上报,即第二DRX组是DRX组a。上述PCell和SCell1-SCell4均为终端设备所配置的服务小区。
在上述示例中,终端设备上报CSI的物理资源可以采用DRX组a关联的服务小区(serving cell),也可以采用DRX组b关联的辅小区(SCell)。本实施例针对的情况是:终端设备上报CSI采用的第二DRX组关联的SCell,与测量CSI的服务小区对应的第一DRX组是不同的DRX组。即,本实施例针对的情况为:第一DRX组是DRX组b,第二DRX是DRX组a;或,第一DRX组是DRX 组a,第二DRX是DRX组b。
终端设备在完成CSI测量后,确定可以进行CSI上报后,可以在第二DRX组的时域位置上,对测量到的CSI进行上报。可选地,终端设备是在第二DRX组的激活期的时域位置上,上报CSI。
综上,本实施例提供的方法,当终端设备配置有至少两个DRX组时,终端设备可以根据测量的CSI参考信号是否位于激活期,确定是否要上报CSI,从而终端设备可以根据该方法有效地上报CSI,避免了由于测量CSI和上报CSI处于不同的DRX组,终端设备无法判断是否需要上报CSI的情况,保障了传输的准确性。
图5示出了本申请一个示例性实施例提供的信道状态信息的上报方法的流程图,本实施例可以单独实施,也可以与图4的实施例结合实施。在本实施例中,包括如下步骤:
步骤510,在CSI参考信号位于第一DRX组的激活期内的情况下,确定上报CSI。
终端设备测量CSI的载波位于第一DRX组的激活期,则终端设备确定向网络设备上报CSI。
步骤520,上报CSI。
其中,第二DRX组是至少两个DRX组中的另一个。终端设备配置有至少两个DRX组,测量CSI的载波位于第一DRX组,预备用来上报CSI的载波位于第二DRX组。
终端设备在完成CSI测量后,确定可以进行CSI上报后,可以在第二DRX组的时域位置上,也可以在第一DRX组的时域位置上,对测量到的CSI进行上报。
可选地,上报CSI的资源位于第二DRX组的时域位置上存在两种情况:
一、上报CSI的资源位于第二DRX组的激活期的时域位置上;
终端设备则会在第二DRX组的激活期的时域位置上,上报CSI。
二、上报CSI的资源位于第二DRX组的非激活期的时域位置上;
终端设备则会更换上报CSI的时域位置,在第一DRX组的激活期的时域位置上,上报CSI。
示例性的,结合参考图6,终端设备配置两个DRX组:DRX group#1和DRX  group#2。由于不同的载波对应不同的DRX组,假设DRX group#1只有一个载波,DRX group#2也只有一个载波。
对于CSI的测量和上报,如图6所示,DRX group#1即为第一DRX组,DRX group#2即为第二DRX组。在周期/半持续调度CSI上报时刻,测量CSI的第一载波处于DRX group#1的激活期。上报CSI的第二载波位置在DRX group#2的非激活期。由于CSI参考信号位于第一DRX组的激活期,终端设备将上报该CSI。
综上,本实施例提供的方法,当终端设备配置有至少两个DRX组时,终端设备可以根据测量的CSI参考信号是否位于激活期,确定是否要上报CSI,从而终端设备可以根据该方法有效地上报CSI,避免了由于测量CSI和上报CSI处于不同的DRX组,终端设备无法判断是否需要上报CSI的情况,保障了传输的准确性。
本实施例提供的方法,在CSI参考信号位于激活期的情况下,终端设备确定上报CSI,以便网络设备能够调度处于激活期的第一载波的数据,提高了传输的有效性。
图7示出了本申请一个示例性实施例提供的信道状态信息的上报方法的流程图,本实施例可以单独实施,也可以与图4或图5的实施例结合实施。在本实施例中,包括如下步骤:
步骤710,在CSI参考信号不位于第一DRX组的激活期内的情况下,确定不上报CSI。
终端设备测量CSI的载波不位于第一DRX组的激活期,则终端设备确定不向网络设备上报CSI。
可选地,上报CSI的资源位于第二DRX组的时域位置上存在两种情况:
一、上报CSI的资源位于第二DRX组的激活期的时域位置上;
二、上报CSI的资源位于第二DRX组的非激活期的时域位置上;
针对上述两种情况,终端设备都不会向网络设备上报CSI。
示例性的,结合参考图8,终端设备配置有两个DRX group:DRX group#1和DRX group#2。不同的载波对应不同的DRX group,假设DRX group#1只有一个载波,DRX group#2也只有一个载波。
对于CSI的测量和上报,如图所示,DRX group#1即为第二DRX组,DRX  group#2即为第一DRX组。在周期/半持续调度CSI上报时刻,测量CSI的第一载波处于DRX group#2的非激活期,上报CSI的第二载波在DRX group#1的激活期。终端设备将不对该CSI进行上报。
综上,本实施例提供的方法,当终端设备配置有至少两个DRX组时,终端设备可以根据测量的CSI参考信号是否位于激活期,确定是否要上报CSI,从而终端设备可以根据该方法有效地上报CSI,避免了由于测量CSI和上报CSI处于不同的DRX组,终端设备无法判断是否需要上报CSI的情况,保障了传输的准确性。
本实施例提供的方法,在CSI参考信号位于非激活期的情况下,由于网络设备无法给不处于激活期的第一载波调度数据,不上报CSI,避免了多余的传输开销。

示例性的,CSI是周期CSI,终端设备通过物理上行控制信道(Physical Uplink Control Channel,PUCCH)资源上报CSI。
示例性的,CSI是半持续CSI,终端设备通过PUSCH资源,或,PUCCH资源上报CSI。
