Description

由用户设备执行的方法以及用户设备 技术领域
本发明涉及无线通信技术领域,具体涉及由用户设备执行的方法以及相应的用户设备。
背景技术
在Rel-15NR中,用户设备基于网络的配置信息,可以执行不同的下行信道测量(measurement)和信道状态信息上报(Channel State Indicator report,CSI report)。测量的配置和对应的上报方式通过上报配置来完成,在3GPP的协议中采用RRC参数CSI-ReportConfig来表示。具体地,上报配置包括如下三方面信息:
1)测量上报的数量,即有多少测量项需要向网络上报。
一个测量报告需要明确配置用户设备需要上报哪些测量项。例如,一个测量报告可以包括三项:信道质量指示(Channel Quality Indicator,CQI)、信道秩指示(Rank Indicator,RI)和信道预编码矩阵指示(Precoder Matrix Indicator,PMI),统称起来称为信道状态信息。测量报告也可以只包括一项,例如报告接收信号强度,称为参考信号接收功率(Reference Signal Received Power,RSRP)。RSRP同样是一项关键的测量,一般用在高层的无线资源管理(Radio Resource Management,RRM)。NR中在物理层引入了RSRP上报,用于波束管理(Beam Management,BM),称为L1-RSRP。
2)测量对象,即下行测量的物理资源
在RRC参数CSI-ReportConfig的配置信息中,上报配置和一个或者多个资源集合关联。具体地,一个测量资源配置和一个或者多个非零功率信道状态信息参考信号(Non Zero Power CSI Reference Signal,NZP-CSI RS)资源集合相关联,用户设备利用该NZP-CSIRS资源集合对下行信道的特性进行测量。NZP-CSI RS资源集合可以包括一组配置的CSI RS或者一组同步信号块(Synchronization Signal Block,SSB)。例如,用于波束管理的L1-RSRP测量上报即针对一组SSB或者一组NZP-CSI RS进行。
3)上报的方式,即利用何种上行物理信道承载CSI上报
在Rel-15NR中,用户设备的CSI上报可以分为三种类型:周期性CSI上报(Periodic CSI report)、半持续性CSI上报(Semi-persistent CSI report)和非周期性CSI上报(Aperiodic CSI report)。
对于周期性CSI上报,网络需要配置一定的上报周期。周期性CSI上报通过物理上行控制信道PUCCH来承载。因此,对于周期性CSI上报,资源配置信息需要配置用来上报的周期性PUCCH资源。
对于半持续性CSI上报,网络通过MAC CE激活或者去激活相应的CSI上报。半持续性CSI上报可以通过分配的PUCCH来承载,也可以通过分配的物理上行共享信道PUSCH来承载。PUSCH往往用来承载上报信息量比较大的半持续性CSI上报。
非周期性CSI上报通过下行控制信息DCI来触发。具体地,通过上行调度授权许可中的CSI request指示域来指示。该指示域最多包含6个比特,每种组合都对应一个配置的非周期性CSI上报,即最多可以触发63个不同的非周期性CSI上报(所有比特置0表示未触发非周期性CSI上报)。非周期性CSI上报通过PUSCH来承载。
在2021年12月3GPP RAN#94e全会上,关于人工智能/机器学习(Artificial Intelligence/Machine Learning,AI/ML)应用在NR空口(NR air interface)中的研究得到批准(参见非专利文献1)。该研究课题的案例(use case)主要包括如下三个方面:
1)CSI上报的增强,例如降低CSI上报的开销(overhead reduction)、提升CSI上报的准确性(improve accuracy)和CSI上报的预测(prediction)等;
2)波束管理的增强,例如时域上的波束预测、空域上开销和时延的降低和波束选择的准确性提升等;
3)不同场景下的定位准确性的增强(positioning accuracy enhancement),例如拥有密集非视距径(Non-Line of Sight,NLOS)的场景等。
本专利的方案是在NR空口中应用AI/ML时用户设备UE确定信道状态信息CSI上报优先级的一种方法,以及,用户设备UE确定非周期性CSI参考信号(CSI-RS)资源的一种方法。

NR中的参数集合(numerology)和NR中的时隙slot
参数集合numerology包含子载波间隔和循环前缀CP长度两方面含义。其中,NR支持5种子载波间隔,分别为15k,30k,60k,120k,240kHz(对应μ=0,1,2,3,4),表格4.2-1示出了支持的传输参数集合,具体如下所示。
表4.2-1 NR支持的子载波间隔
仅当μ=2时,即60kHz子载波间隔的情况下支持扩展(Extended)CP,其他子载波间隔的情况仅支持正常CP。对于正常(Normal)CP,每个时隙(slot)含有14个OFDM符号;对于扩展CP,每个时隙含有12个OFDM符号。对于μ=0,即15kHz子载波间隔,1个时隙=1ms;μ=1,即30kHz子载波间隔,1个时隙=0.5ms;μ=2,即60kHz子载波间隔,1个时隙=0.25ms,以此类推。
NR和LTE对于子帧(subframe)的定义相同,表示1ms。对于子载波间隔配置μ,1个子帧内(1ms)的slot编号可以表示为范围为0到1个系统帧(frame,时长10ms)内的slot编号可以表示为范围为0到其中,在不同子载波间隔μ的情况的定义如下表格所示。
表格4.3.2-1:正常CP时每个slot包含的符号数,每个系统帧包含的slot数,每个子帧包含的slot数
表格4.3.2-2:扩展CP时(60kHz)每个slot包含的符号数,每个系统帧包含的slot数,每个子帧包含的slot数
在NR载波上,系统帧(或者,简称为帧)的编号SFN范围为0至1023。
资源块RB和资源单元RE
资源块RB在频域上定义为个连续的子载波,例如对于15kHz的子载波间隔,RB在频域上为180kHz。对于子载波间隔15kHz×2μ,资源单元RE在频域上表示1个子载波,在时域上表示1个OFDM符号。
NR公共资源块(Common RB,CRB)
公共资源块CRB是针对参数集numerology定义的。对所有numerology,公共资源块CRB编号0的子载波0的中心频率都指向频域的同一个位置,这个位置称为“A点”(point A)。
NR资源栅格(resource grid)
在一个载波(carrier)的一个给定的传输方向上(用x表示,其中若x=DL则表示下行,若x=UL则表示上行),对每一个numerology都定义了一个资源栅格,其在频域上包含个子载波(即个资源块RB,每个资源块包含个子载波subcarrier),在时域上包含个OFDM符号(表示一个子帧内的OFDM符号数,具体取值和μ有关),其中指一个资源块RB中的子载波个数,满足资源栅格的最低编号的公共资源块(common resourceblock,CRB)由高层参数offsetToCarrier配置,频域资源块个数由高层参数carrierBandwidth配置。其中,对于给定的numerology以及高层参数offsetToCarrier,gNB通过专用信令(dedicated signaling)在ServingCellConfigCommon IE中配置小区特定(cell specific)的公共(common)offsetToCarrier。具体为:ServingCellConfigCommon中包括高层参数downlinkConfigCommon,在downlinkConfigCommon中包含offsetToCarrier的配置信息。
带宽片段(BWP)
在NR中,对每一个参数集numerology,可以定义一个或者多个带宽片段。每个BWP包含一个或者多个连续的CRB。假设某个BWP的编号为i,则其起点(或者,用来表示)和长度(或者,用来表示)必须同时满足以下关系:
即该BWP所包含的CRB必须位于所对应numerology的资源栅格内。使用CRB编号,表示BWP的最低编号的CRB到point A的距离,以RB为单位。
BWP内的资源块称为物理资源块(physical resource block,PRB),其编号为其中物理资源块0对应该BWP的最低编号的CRB,即CRB对于某个serving cell,gNB通过如下高层参数配置某个BWP:
1)子载波间隔;
2)CP长度;
3)高层参数locationAndBandwidth指示该BWP相对于资源栅格起始CRB的偏移值offset(RBstart)和该BWP频域上连续CRB的个数LRB,满足其中Ocarrier表示offsetToCarrier;其中,参数locationAndBandwidth指示一个RIV(Resource Indication Value,资源指示值)。RIV关于LRB和RBstart的计算关系为:如果那么 否则, 其中,并且,
4)该BWP的编号;
5)BWP公共和BWP专有的参数配置,例如下行BWP的PDCCH和PDSCH的配置等。
NR中的信道状态信息上报(CSI report)
在NR中,用户设备基于网络的配置信息,可以执行不同的下行信道测量(measurement)和信道状态信息上报(Channel State Indicatorreport,CSI report)。测量的配置和对应的上报方式通过上报配置来完成,在3GPP的协议中采用RRC参数CSI-ReportConfig来表示。
CSI上报的报告项目
一个测量报告需要明确配置用户设备需要上报哪些测量项。例如,一个测量报告可以包括三项:信道质量指示(Channel Quality Indicator,CQI)、信道秩指示(Rank Indicator,RI)和信道预编码矩阵指示(Precoder Matrix Indicator,PMI),统称起来称为信道状态信息。测量报告也可以只包括一项,例如报告接收信号强度,称为参考信号接收功率(Reference Signal Received Power,RSRP)。RSRP同样是一项关键的测量,一般用在高层的无线资源管理(Radio Resource Management,RRM)。NR中在物理层引入了RSRP上报,用于波束管理(Beam Management,BM),称为L1-RSRP。
CSI上报的物理测量资源
在RRC参数CSI-ReportConfig的配置信息中,上报配置和一个或者多个资源集合关联。具体地,一个测量资源配置和一个或者多个非零功率信道状态信息参考信号(Non Zero Power CSI Reference Signal,NZP-CSI RS)资源集合相关联,用户设备利用该NZP-CSIRS资源集合对下行信道的特性进行测量。NZP-CSI RS资源集合可以包括一组配置的CSI RS或者一组同步信号块(Synchronization Signal Block,SSB)。例如,用于波束管理的L1-RSRP测量上报即针对一组SSB或者一组NZP-CSI RS进行。
CSI上报的上报方式
在NR中,用户设备的CSI上报可以分为三种类型:周期性CSI上报(Periodic CSI report)、半持续性CSI上报(Semi-persistent CSI report)和非周期性CSI上报(Aperiodic CSI report)。
对于周期性CSI上报,网络需要配置一定的上报周期。周期性CSI上报通过物理上行控制信道PUCCH来承载。因此,对于周期性CSI上报,资源配置信息需要配置用来上报的周期性PUCCH资源。
对于半持续性CSI上报,网络通过MAC CE激活或者去激活相应的CSI上报。半持续性CSI上报可以通过分配的PUCCH来承载,也可以通过分配的物理上行共享信道PUSCH来承载。PUCCH资源是半静态周期性配置的。PUSCH往往用来承载上报信息量比较大的半持续性CSI上报。
非周期性CSI上报通过下行控制信息DCI来触发。具体地,通过上行调度授权许可中的CSI request指示域来指示。该指示域最多包含6个比特,每种组合都对应一个配置的非周期性CSI上报,即最多可以触发63个不同的非周期性CSI上报(所有比特置0表示未触发非周期性CSI上报)。非周期性CSI上报通过PUSCH来承载。
CSI上报的优先级
在NR中,用户设备UE需要确定每一个CSI上报的优先级数值。优先级数值越大,表示该CSI上报的优先级越低;优先级数值越小,表示该CSI上报的优先级越高。
人工智能/机器学习(AI/ML)
在本发明的说明书中,采用AI/ML模型(model)来表示在NR空口中应用了AI/ML技术。在CSI增强的案例中,AI/ML模型包括CSI生成模型(CSI generation model,或者称为编码器encoder或者自动编码器auto-encoder)和CSI重构模型(CSI reconstruction model,或者称为解码器decoder或者自动解码器auto-decoder)。在波束管理的增强案例中,当UE应用了AI/ML模型时,可以用于生成上报的波束测量信息。当网络应用AI/ML模型时,可以为UE配置两个参考信号集合。这两个集合可以是不同的,其中一个用于波束测量,另外一个集合表示需要上报的波束。
AI/ML技术可以分为如下5个方面:
1)AI/ML模型的训练(model training)
AI/ML模型的训练表示根据输入参数和输出参数的组合得到一个推理关系(例如,一个函数),用于后续的推理。以CSI生成模型为例,该模型可以由网络训练,或者由UE训练得到。该模型的输入参数是信道的原始数据(例如,信道的原始矩阵),输出参数是向网络上报的CSI。相反地,对于CSI重构模型,同样可以由网络训练,或者由UE训练得到。CSI重构模型的输入参数是上报的CSI,输出参数是信道的原始数据。
2)AI/ML模型的转移(model transfer)
如果CSI生成模型由网络训练,那么训练得到的CSI生成模型可以由网络发送给UE,用于UE的模型推理。模型的发送称为AI/ML模型的转移。
3)AI/ML模型的推理(model inference)
以CSI生成模型为例,UE使用了一个CSI生成模型生成CSI上报的过程即为AI/ML模型的推理过程。类似地,网络使用了一个CSI重构模型生成信道原始数据的过程也是AI/ML模型的推理。
4)AI/ML模型的监控(model monitoring)
网络或者UE需要对使用的AI/ML模型进行监控,以判断使用的模型是否适用于当前的信道状态。
5)AI/ML模型的更新(model update)
当网络或者UE认为模型不再适用时,将对AI/ML模型进行模型更新。
