下面对本申请实施例提供的CSI测量和上报方法、装置、设备、系统及存储介质中涉及的一些概念和/或术语做一下解释说明。
1、灵活双工(Flexible duplex)
在部署传统的蜂窝网络时,基于可用的频谱,以及业务特性等,可采用频分双工(Frequency Division Duplex,FDD)或时分双工(Time Division Duplex,TDD)的双工方式。当采用FDD时,上行传输和下行传输位于不同的频点上,两者互不干扰,可同时进行。当采用TDD时,上行传输和下行传输位于同一个频点上,采用时分的方式交错进行。
为了更灵活地利用有限的频谱资源,以动态地匹配业务需求,提升资源利用效率,提出了灵活的双工方式。一种灵活双工方式为:网络侧全双工,即在同一时刻,上行传输和下行传输可在不同的频域位置同时进行,为避免上下行之间的干扰,可在对应不同传输方向的频域位置(对应双工子带)之间留出一定的保护频带(Guard Band);UE侧半双工,即与TDD一致,在同一时刻,只能作上行传输或下行传输,两者不可同时进行。可以理解的是,在这种双工方式下,网络侧在同一时刻的上行传输和下行传输只能针对不同的UE。
图2给出了上述灵活双工方式的示意图,网络侧将频域半静态划分为三个双工子带。在第三个时隙内,UE1和UE2分别作下行接收和上行发送。
2、CSI测量和上报
为了便于网络侧获取与某个UE之间的下行信道的特性(包括秩指示(Rank Indication,RI)/预编码矩阵指示(Precoding Matrix Indicator,PMI)/信道质量指示(Channel Quality Indicator,CQI)等),以更有效地调度针对此UE的下行数据传输,引入了CSI测量和上报机制。在NR中,对于CSI测量和上报机制作了泛化,将为UE侧配置时频跟踪资源,以及参考信号接收功率(Reference Signal Receiving Power,RSRP)测量资源等操作也纳入此机制。
基于CSI测量和上报的时域操作属性,以及承载CSI报告(Report)的上行信道类型,可以区分如下上报配置类型(Reporting Config Type):基于物理上行控制信道(Physical Uplink Control Channel,PUCCH)的周期性CSI(Periodic CSI on PUCCH)、基于PUCCH的半持续CSI(Semi-persistent CSI on PUCCH)、基于物理上行共享信道(Physical Uplink Shared Channel,PUSCH)的半持续CSI(Semi-persistent CSI on PUSCH)、基于PUSCH的非周期CSI(Aperiodic CSI on PUSCH)。基于各种Reporting Config Type可支持/使用的CSI-RS配置可知,CSI-RS资源的出现频度必须不小于CSI Report的上报频度。
基于CSI测量和上报的上报内容,可以区分如下CSI上报量(CSI Report Quantiy):取值可以为'none','cri-RI-PMI-CQI','cri-RI-i1','cri-RI-i1-CQI','cri-RI-CQI','cri-RSRP','cri-SINR','ssb-Index-RSRP','ssb-Index-SINR','cri-RI-LI-PMI-CQI'。
基于CSI测量和上报的上报信息的频域粒度,可以区分如下频域粒度(Frequency granularity):取值可以为宽带频域粒度(Wideband frequency-granularity),子带频域粒度(Sub-band frequency-granularity)。当需要针对CSI Sub-band(即在CSI Report Config中基于参数sub-band Size确定的子带;可选地,可进一步基于参数CSI上报频带(CSI-Reporting Band)确定CSI Sub-band集合)上报CQI和/或PMI时,认为对应子带频域粒度。
下面结合附图,通过一些实施例及其应用场景对本申请实施例提供的CSI测量和上报方法进行详细地说明。
在前述灵活双工方式下,当CSI测量和上报关联的CSI资源占用的部分或所有RE基于网络侧的配置或指示,不适合或无法用于下行传输时,UE如何进行CSI测量和上报,以提升CSI测量和上报的精度,或者降低CSI测量和上报的开销,目前并没有明确的解决方案。
本申请实施例中,在灵活双工方式下,为了提升CSI测量和上报的精度,或者降低CSI测量和上报的开销,UE可以根据网络侧配置的用于CSI测量和上报的CSI资源的冲突情况,执行与CSI测量和上报相关的操作。
具体的,本申请的一种方案一(即下述步骤202a和步骤202b及其相关方案),网络侧设备提供冗余的CSI测量和上报配置信息/配置资源,由UE根据CSI测量和上报配置信息/配置资源对应的CSI资源的冲突情况,选择其中的部分或所有CSI测量和上报配置信息/配置资源,以避免或降低冲突。
本申请的另一种方案二(即下述步骤202c至步骤202g及其相关方案),UE基于网络侧设备提供的CSI测量和上报配置信息/配置资源,根据CSI测量和上报配置信息/配置资源对应的CSI资源的冲突情况,在CSI测量和上报时执行相关操作,以避免或降低冲突。
可选地,本申请实施例中,这两种方案可以结合使用,例如,基于方案一,网络侧提供冗余的CSI测量和上报的配置信息/配置资源,由UE根据CSI测量和上报配置信息/配置资源对应的CSI资源的冲突情况,选择其中的部分或所有CSI测量和上报配置信息/配置资源,当UE应用的配置信息对应的CSI资源仍存在冲突时,UE可以进一步应用方案二,基于CSI测量和上报配置信息/配置资源对应的CSI资源的冲突情况,在CSI测量和上报时执行相关操作,以进一步避免或降低冲突。
具体的,本申请实施例提供一种CSI测量和上报方法,图3示出了本申请实施例提供的一种CSI测量和上报方法的流程图。如图3所示,本申请实施例提供的CSI测量和上报方法可以包括下述的步骤201和步骤202。
步骤201、UE获取目标配置信息。
本申请实施例中,上述目标配置信息指示用于CSI测量和上报的CSI资源。
可选地,本申请实施例中,UE获取目标配置信息的方式可以为以下任一项:预定义、预配置、协议约定、网络侧配置。
步骤202、UE根据目标配置信息对应的CSI资源的冲突情况,执行与CSI测量和上报相关的操作。
本申请实施例中,CSI资源的冲突情况可以理解为:CSI资源是否存在冲突,以及CSI资源的冲突程度。
可选地,本申请实施例中,CSI资源是否存在冲突的判断方式为:若一个CSI资源或该一个CSI
资源的预定义传输机会占用的RE满足预设条件,则该一个CSI资源存在冲突。其中,预设条件为RE位于网络侧配置的保护频带中,或被网络侧配置/指示为用于上行传输的RE或灵活RE。
需要说明的是,当某个RE位于网络侧配置的保护频带(Guard Band)中,或被网络侧配置/指示为用于上行传输的RE或灵活(Flexible)RE时,该某个RE被判断为非法,即该某个RE满足预设条件。
本申请实施例中,CSI资源的冲突程度可以理解为:CSI资源或CSI资源的预定义传输机会占用的RE被判断为非法的数目或比例,可以进一步理解为,CSI资源或CSI资源的预定义传输机会占用的所有RE中,被判断为非法的RE数目,或者被判断为非法的RE数目与所有RE数目的比例。
对于某个CSI上报配置(即CSI的配置信息),冲突程度可以理解为:基于此CSI上报配置关联/对应的各个CSI资源的冲突程度确定的单个取值,例如取各个CSI资源的冲突程度的平均值;或者,基于CSI上报配置关联的用于特定用途(例如用于信道测量)的各个CSI资源的冲突程度确定的单个取值,例如取各个CSI资源的冲突程度的平均值;或者,此CSI上报配置关联的各个CSI资源占用的所有RE中,被判断为非法的RE数目,或者被判断为非法的RE数目与所有RE数目的比例;或者,此CSI上报配置关联的用于特定用途的各个CSI资源占用的所有RE中,被判断为非法的RE数目,或者被判断为非法的RE数目与所有RE数目的比例;或者,此CSI资源(即CSI上报配置关联的各个CSI资源或CSI上报配置关联的用于特定用途的各个CSI资源)的预定义传输机会(Occasion)占用的所有RE中,被判断为非法的RE数目,或者被判断为非法的RE数目与所有RE数目的比例。需要说明的是,当上述数目或比例越小时,可以理解为冲突程度越轻或越小。
可选地,本申请实施例中,上述目标配置信息对应的CSI资源可以包括以下至少一项:
用于信道测量的非零功率信道状态信息参考信号(Non-Zero Power Channel State Information-Reference Signal,NZP CSI-RS)资源或资源集合;
用于干扰测量的NZP CSI-RS资源或资源集合;
同时用于信道测量和干扰测量的NZP CSI-RS资源或资源集合;
用于干扰测量的信道状态信息干扰测量(Channel State Information-Interference Measurement,CSI-IM)资源或资源集合。
可选地,在本申请实施例的一种实现方式中,上述步骤202具体可以通过下述的步骤202a实现。
步骤202a、在目标配置信息包括多套配置信息的情况下,UE从多套配置信息中确定第一配置信息,并基于第一配置信息对应的CSI资源,执行CSI测量和上报。
本申请实施例中,上述第一配置信息为多套配置信息中CSI资源不存在冲突或冲突程度最小的配置信息。
可以理解,网络侧配置多套配置信息(CSI Report Config),UE只选择关联/对应的CSI资源不存在冲突,或者冲突程度最轻或最小的CSI Report Config进行对应的CSI测量和上报。
可选地,本申请实施例中,上述步骤202a中的“UE从多套配置信息中确定第一配置信息”具体可以通过下述的步骤202a1或步骤202a2实现。
步骤202a1、UE将至少一套第二配置信息中的N套配置信息,确定为第一配置信息。
本申请实施例中,上述至少一套第二配置信息中的每套第二配置信息为多套配置信息中与一个时间单元关联、且CSI资源不存在冲突的配置信息,N为正整数。
步骤202a2、针对目标CSI上报类型,UE将至少一套第二配置信息中的N套配置信息,确定为第一配置信息。
本申请实施例中,假设与某套配置信息关联/对应的CSI资源,或者用于特定用途(例如用于信道测量)的CSI资源,或此CSI资源的预定义传输机会占用的RE位于某一时间单元(例如时隙)内,则认为此套配置信息与此时间单元关联。
当CSI资源为非周期(Aperiodic)CSI资源时,此CSI资源只对应单个传输机会(例如图4中,只涉及CSI资源的传输机会1),或者,此CSI资源不涉及传输机会的概念(因为只对应时域单次传输),上述描述应用于此CSI资源或此CSI资源对应的单个传输机会。
当CSI资源为周期性(Periodic)CSI资源或半持续(Semi-persistent)CSI资源时,此CSI资源对应多个传输机会(例如图4中,给出了此CSI资源对应的传输机会1和传输机会2,基于为此CSI资源配置的周期,在时间轴往前,可能还会有更多的传输机会与此CSI资源对应)。上述预定义传输机会为此多个传输机会中的一个或多个。例如,上述预定义传输机会为此CSI资源相对于CSI报告的传输时刻,不晚于CSI参考资源(reference resource)(时域对应单个下行slot)的单个最近的传输机会。
可选地,本申请实施例中,上述N套配置信息由UE根据以下至少一项确定:CSI上报类型信息、配置信息的标识信息。
可以理解,对于分别与某个时间单元关联,且关联的CSI资源不存在冲突的CSI Report Config(即上述至少一套第二配置信息),UE从中选择一套或多套CSI Report Config进行对应的CSI测量和上报。当候选的CSI Report Config数目多于所需数目(例如N)时,UE可以基于CSI Report Config ID(配置信息的标识信息)进行选择,例如选择CSI Report Config ID最小或最大的一套或多套CSI Report Config。可选地,UE也可以基于CSI上报类型信息选择CSI Report Config,例如对于各种CSI上报类型给出预定义的排序规则,并从中选择一套或多套CSI Report Config。可选地,当某种CSI上报类型对应的CSI Report Config数目多于所需数目时,UE可以进一步基于CSI Report Config ID进行选择。
对于分别与某个时间单元关联,且关联的CSI资源不存在冲突的CSI Report Config,针对某种CSI上报类型,UE从中选择一套或多套CSI Report Config进行对应的CSI测量和上报。
特别地,当多套配置信息中与一个时间单元关联的各个配置信息对应的CSI资源都存在冲突时,UE针对此时间单元,无需执行CSI测量和上报操作。
可选地,本申请实施例中,上述CSI上报类型信息基于以下至少一项确定:CSI上报量、CSI上报配置类型、CSI频域粒度、承载CSI报告的信道类型。
可选地,本申请实施例中,上述CSI上报量(Report Quantiy)取值可以包括以下至少一项:'none'、'cri-RI-PMI-CQI'、'cri-RI-i1'、cri-RI-i1-CQI'、'cri-RI-CQI'、'cri-RSRP'、'cri-SINR'、'ssb-Index-RSRP'、'ssb-Index-SINR'、'cri-RI-LI-PMI-CQI'。
可选地,本申请实施例中,上述CSI上报配置类型(Reporting Config Type)取值可以包括以下至少一项:由PUCCH承载的周期性CSI(Periodic CSI on PUCCH)、由PUCCH承载的半持续CSI(Semi-persistent CSI on PUCCH)、由PUSCH承载的半持续CSI(Semi-persistent CSI on PUSCH)、由PUSCH承载的非周期CSI(Aperiodic CSI on PUSCH)。
可选地,本申请实施例中,上述CSI频域粒度是针对上报量的频域粒度。CSI频域粒度(Frequency granularity)取值可以包括以下至少一项:宽带频域粒度(Wideband frequency-granularity),子带频域粒度(Sub-band frequency-granularity)。
可选地,本申请实施例中,上述承载CSI报告的信道类型取值可以包括以下至少一项:由PUCCH承载的CSI报告(CSI Reporting on PUCCH)、由PUSCH承载的CSI报告(CSI Reporting on PUSCH)。
可选地,本申请实施例中,上述步骤202a中的“UE从多套配置信息中确定第一配置信息”具体可以通过下述的步骤202a3或步骤202a4实现。

特别地,当多个CSI资源中用于特定测量的CSI资源都存在冲突时,UE针对第四配置信息无需执行CSI测量和上报操作。
步骤202b2、UE将至少一套第二CSI资源中的L套CSI资源,确定为目标CSI资源。
本申请实施例中,上述至少一套第二CSI资源为多套CSI资源中用于特定测量的CSI资源,L套CSI资源为至少一套第二CSI资源中冲突程度最小的CSI资源,L为正整数。

步骤202c、UE基于预设规则,在目标配置信息对应的CSI资源上执行CSI测量和上报。
本申请实施例中,UE在接收NZP CSI-RS或测量CSI-IM时,不对可能的冲突作额外的判断或假设。例如,UE假设与某套配置信息(CSI Report Config)关联的NZP CSI-RS资源或此NZP CSI-RS资源的预定义传输机会占用的各个RE上均存在有效的CSI-RS传输,和/或,UE假设与某套配置信息关联的CSI-IM资源或此CSI-IM资源的预定义传输机会占用的各个RE上均可测量到有效的干扰情况。

可选地,本申请实施例中,对于目标配置信息对应的Periodic/Semi-persistent CSI资源,UE可以为该CSI资源确定可用传输机会,并针对可用传输机会执行CSI测量和上报。对于目标配置信息对应的Aperiodic CSI资源,该CSI资源只对应单个传输机会,或不涉及传输机会的概念,即上述步骤202d的方案不适用Aperiodic CSI资源;或者,对于Aperiodic CSI资源,UE可以直接判断该资源或该资源对应的单个传输机会是否为可用传输机会。
可选地,本申请实施例中,上述步骤202d中的“UE为目标配置信息对应的CSI资源确定可用传输机会”具体可以通过下述的步骤202d1或步骤202d2实现。

步骤202d2、在目标配置信息未配置用于特定测量的时间限制信息的情况下,针对目标配置信息对应的用于特定测量的第四CSI资源,UE将第四CSI资源最近的一个或多个可用传输机会,确定为第四CSI资源的可用传输机会。
本申请实施例中,当CSI测量和上报对应的CSI Report Config配置了信道测量在时域上的限制(Time Restriction For Channel Measurements,应用于用作信道测量的CSI资源),或干扰测量在时域
上的限制(Time Restriction For Interference Measurements,应用于用作干扰测量的CSI资源)时,UE针对某个CSI资源只寻找最近的单个可用传输机会。当CSI测量和上报对应的CSI Report Config未配置信道测量在时域上的限制或干扰测量在时域上的限制时,UE针对某个CSI资源可寻找一个或多个可用传输机会(典型情况下寻找最近的一到多个可用传输机会,可基于UE实现确定),并在这一个或多个可用传输机会上作统一的测量,或者对这一个或多个可用传输机会中各个可用传输机会的测量结果取平均或作平滑。可选地,UE将针对多个可用传输机会获取的测量结果与历史测量结果取平均或作平滑。
可选地,本申请实施例中,在第四CSI资源为一个资源集合的情况下,一个资源集合对应一个可用传输机会,或者一个资源集合中的各个资源分别对应一个可用传输机会。
可以理解,在为某个CSI资源寻找可用传输机会时,如果此CSI资源对应单个资源集合(例如,NZP CSI-RS Resource Set,SSB Resource Set,CSI-IM Resource Set),既可以针对此资源集合统一寻找可用传输机会,也可以针对此资源集合中的各个资源分别寻找可用传输机会。

(1)在目标配置信息对应的CSI资源存在冲突,或者目标配置信息对应的CSI资源的冲突程度高于或不低于第一门限值的情况下,UE不执行/忽略目标配置信息对应的CSI上报;
可以理解,在方式(1)中,对于关联的CSI资源存在冲突的某套配置信息(CSI Report Config),或者冲突程度高于或不低于第一门限值的某套配置信息,UE可以忽略对应的CSI上报,即认为无需传输此套配置信息对应的CSI报告。
(2)在UE需要上报子带CSI(Sub-band CSI)的情况下,UE仅上报可用CSI子带对应的子带CSI;
可选地,本申请实施例中,UE是否需要上报子带CSI和/或宽带CSI,是基于目标配置信息确定,CSI可以包括RI、层指示(Layer Indicator,LI)、PMI、CQI、RSRP、信号干扰噪声比(Signal to Interference and Noise Ratio,SINR)等。
需要说明的是,本申请实施例中,对于CSI上报频带(CSI Reporting Band)内的某个CSI子带,如果某项CSI Report Config关联的CSI资源在此CSI子带内存在冲突,或者此项CSI Report Config在
此CSI子带内的冲突程度高于或不低于第一门限值,则认为此CSI子带不是可用CSI子带,或者为不可用CSI子带。

(4)在UE需要上报子带CSI的情况下,UE针对不可用CSI子带对应的子带CSI上报非法值;
本申请实施例中的非法值,可以理解为协议规定或高层信令配置的无效取值。在NR中,CQI index0对应Out-of-range,可以认为是针对CQI的非法值。对于除CQI之外的其它CSI信息,例如RI、LI、PMI、RSRP、SINR等,也可以协议规定或高层配置各自对应的非法值。
可以理解,在方式(4)中,当UE需要上报子带CSI时,在组织与CSI Report Config对应的CSI报告时,配置的CSI上报频带对应的各个CSI子带对应的子带CSI均包含在此CSI报告中,其中,被判断为不可用CSI子带的CSI子带对应的子带CSI设置为对应的非法值,被判断为可用CSI子带的CSI子带对应的子带CSI按现有规则测量和设置取值即可。
(5)在UE需要上报宽带CSI、且上报频带(CSI Reporting Band)内包含不可用CSI子带的情况下,UE针对宽带CSI上报非法值;
(6)在UE需要上报子带CSI的情况下,UE不更新不可用CSI子带对应的子带CSI;

UE上报第一CSI报告,该第一CSI报告为针对目标配置信息最近上报的CSI报告;
UE上报第二CSI报告,该第二CSI报告中的各项信息设置为对应的非法值或默认值。
本申请实施例中,在方式(8)中,UE不要求更新CSI报告,UE可以上报针对CSI Report Config最近上报的CSI报告,或者,UE针对CSI报告涉及的各项信息上报非法值(即无效取值,例如Out-of-range)、默认值(可对应较为保守的取值,由协议规定或高层信令配置,例如RI=1,CQI index=6等)。例如,对于某项配置为非周期的CSI Report Config,当UE针对此CSI Report Config从未上报过对应的CSI报告时,UE按照配置或规定的格式组织对应的CSI报告,但此CSI报告中包含的各项信息都设置为对应的非法值/默认值;当UE针对此CSI Report Config上报过对应的CQI报告时,直接重传此CQI报告,或者当此CQI报告上次传输的时刻相对于本次上报时刻之间的时间间隔小于或不超过预定义取值时重传此CQI报告,否则上报一个各项信息设置为非法值/默认值的CQI报告。
需要说明的是,在目标上报方式包括方式(7)和方式(2)的情况下:(a)当UE需要上报子带CSI时,UE仅上报可用CSI子带对应的子带CSI;(b)当UE需要上报宽带CSI时,UE基于目标子
带(CSI上报频带对应的各个CSI子带)对应的子带CSI确定上报的宽带CSI,CSI上报频带对应的CSI子带中可能存在不可用CSI子带,此时基于这个/这些不可用CSI子带的最近测量或上报的子带CSI,或者默认值,以及其它可用CSI子带对应的子带CSI,来推导宽带CSI。
需要说明的是,上述方式(2)可以与方式(3)组合使用(当基于对应的CSI Report Config,UE需要同时上报子带CSI以及宽带CSI时,UE可针对子带CSI和宽带CSI分别采用方式(2)和方式(3));上述方式(4)可以与方式(5)组合使用(当基于对应的CSI Report Config,UE需要同时上报子带CSI以及宽带CSI时,UE可针对子带CSI和宽带CSI分别采用方式(4)和方式(5));上述方式(6)可以与方式(7)组合使用(当基于对应的CSI Report Config,UE需要同时上报子带CSI以及宽带CSI时,UE可针对子带CSI和宽带CSI分别采用方式(6)和方式(7)),对于其它可能的方式组合使用不作限定(例如,上述方式(2)也可以与方式(7)结合使用,此时不可用CSI子带对应的子带CSI不作上报,但用于推导宽带CSI)。
基于上述方式(1),当UE需要上报CSI报告时,CSI报告内包含的各项信息对应的比特数,以及CSI报告的总比特数与现有技术一致;上述方式(3)/(4)/(5)/(6)/(7)/(8)并不改变现有技术中CSI报告的对应信息的比特数;上述方式(2)可能会改变现有技术中CSI报告的对应信息的比特数。当改变(或减少)比特数时,可以降低CSI上报开销。
