背景技术
在波束管理中,终端设备可以对网络设备的多个发送波束或自身的多个接收波束进行测量,得到波束测量信息,并根据不同的应用场景确定向网络设备上报的CSI信息中是否为波束测量信息。例如,当终端设备测量基站的多个发送波束,或测量网络设备的多个发送波束以及自身的多个接收波束时,终端设备向网络设备上报的CSI信息中为波束测量信息;当网络设备固定一个发送波束,终端设备在该发送波束上测量自身的多个接收波束时,终端设备向网络设备上报的CSI信息为无内容,即不向网络设备上报波束测量信息。
通常,终端设备在进行波束测量时,需要占用终端设备中CSI处理单元,并确定CSI处理单元的占用时间。然而,在波束管理中,相关技术还无法确定CSI处理单元的占用时间。

具体实施方式
在波束管理中,网络设备(例如传输接收点(Transmission Reception Point,TRP))可以有多个发送波束,终端设备也可以有多个接收波束。通常,终端设备在与基站通信之前,可以对网络设备的多个发送波束或自身的多个接收波束进行测量,以确定与网络设备通信时网络设备使用的最佳发送波束或自身使用的最佳接收波束。
终端设备在进行波束测量时,可以由网络设备通过配置同步信号块(Synchronisation Signal Block,SSB)资源或信道状态信息参考信号 (Channel State Information-Reference Signals,CSI-RS)资源实现,其中,不同的SSB资源或CSI-RS资源上的信号可以通过不同的发送波束发送,终端设备可以根据接收到的信号强度等参数实现波束测量。
以下以三种典型的应用场景为例进行说明:
第一种应用场景,终端设备对网络设备的多个发送波束和自身的多个接收波束进行测量。
具体地,终端设备可以在网络设备的每一个发送波束上,扫描自身的多个接收波束,根据多个接收波束接收到的信号强度等参数,确定每一个发送波束对应的最佳接收波束,基于这些最佳接收波束,可以确定对应的一个或多个发送波束。
第二种应用场景,终端设备对网络设备的多个发送波束进行测量。
具体地,终端设备可以固定一个接收波束,在该接收波束上,可以扫描网络设备的多个发送波束,根据从多个发送波束接收到的信号强度等参数,确定一个或多个最佳发送波束。
第二种应用场景可以视为上述第一种应用场景的特例,相较于第一种应用场景而言,可以实现小范围的更为精确的发送波束扫描。
第三种应用场景:终端设备对自身的多个接收波束进行测量。
具体地,网络设备可以固定一个发送波束,终端设备在网络设备固定的发送波束上,扫描自身的多个接收波束,根据多个接收波束接收到的信号强度等参数,确定一个或多个最佳接收波束。
上述第一种应用场景为上述第二种应用场景和上述第三种应用场景的组合。终端设备在上述三种应用场景下进行波束测量后,可以得到相应的波束测量信息,并记录在终端设备中。其中,在上述第一种应用场景和第二种应用场景下,终端设备可以将波束测量信息作为CSI信息上报给网络设备,以便网络设备可以使用合适的发送波束与终端设备通信。在上述第三种应用场景下,由于网络设备的发送波束固定,因此,终端设备向网络设备上报的CSI信息为无内容,即不将波束测量信息上报给网络设备,这样,当网络设备使用固定的发送波束与终端设备通信时,终端设备可以基于本地记录的波束测量信息选择合适的接收波束。
终端设备在将波束测量信息以CSI报告的方式上报给网络设备之前,网络设备可以向终端设备指示CSI报告配置。
具体地,网络设备可以向终端设备发送无线资源控制(Radio Resource Control,RRC)信令,并将CSI报告配置(CSI-Report Config)携带在RRC信令中。其中,在波束管理中,CSI报告配置中报告量(reportQuantity)的配置选项主要可以包括:cri-参考信号接收功率(cri-Reference Signal Receiving Power,cri-RSRP)、ssb-Index-RSRP,或,none。
终端设备在接收到网络设备指示的CSI报告配置后,可以基于指示得到相应的波束测量信息。
终端设备在得到波束测量信息时,通常需要占用终端设备中的CSI处理单元。其中,如果终端设备可以同时支持N个CSI的计算,意味着终端设备具有N个CSI处理单元,在一个给定的正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)符号中,如果终端设备中有L个CSI处理单元被占用,那么,终端设备就有N-L个可用的CSI处理单元。
然而,在波束管理中,相关技术还无法明确CSI处理单元的占用时间。
有鉴于此,本公开实施例提供一种确定信道状态信息CSI处理单元占用时间的方法、终端设备,该方法应用于终端设备,包括:根据CSI报告配置中的CSI报告类型,确定所述CSI处理单元的占用时间,所述CSI报告类型包括所述终端设备向网络设备上报的CSI信息为波束测量信息,或向所述网络设备上报的CSI信息为无内容且信道状态信息参考信号CSI-RS资源不用于跟踪参考信号TRS测量。
本公开实施例所述的CSI信息为无内容,可以理解为CSI报告配置中的报告量可以设置为none。
这样,在波束管理中,在向网络设备上报的CSI信息为波束测量信息以及上报的CSI信息为无内容且CSI-RS资源不用于TRS测量两种应用场景下,确定终端设备中CSI处理单元的占用时间时,可以基于本公开实施例提供的技术方案,明确CSI处理单元的占用时间,终端设备和网络设备的行为更加清晰。
下面将结合本公开实施例中的附图,对本公开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公开一部分实施例,而不是全部的实施例。基于本公开中的实施例,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,都属于本公开保护的范围。
本公开的技术方案,可以应用于各种通信系统,例如:全球移动通讯系统(Global System of Mobile communication,GSM),码分多址(Code Division Multiple Access,CDMA)系统,宽带码分多址(Wideband Code Division Multiple Access,WCDMA),通用分组无线业务(General Packet Radio Service,GPRS),长期演进(Long Term Evolution,LTE)/增强长期演进(Long Term Evolutionadvanced,LTE-A),新空口(New Radio,NR)等。
终端设备可以理解为用户端(User Equipment,UE),也可称之为移动终端(Mobile Terminal)、移动用户设备等,可以经无线接入网(例如,Radio Access Network,RAN)与一个或多个核心网进行通信,用户设备可以是移动终端,如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机,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,用户设备也可以是无人机、飞行器等飞行设备,它们与无线接入网交换语言和/或数据。
基站,可以是GSM或CDMA中的基站(Base Transceiver Station,BTS),也可以是WCDMA中的基站(NodeB),还可以是LTE中的演进型基站(eNB或e-NodeB,evolutional Node B)及5G基站(gNB),本公开并不限定,但为描述方便,下述实施例以gNB为例进行说明。
本公开的应用场景至少可以包括两种应用场景,即终端设备对网络设备的多个发送波束进行测量,终端设备对自身的多个发送波束进行测量。在这两种应用场景下,终端设备可以基于本公开实施例提供的技术方案,明确终端设备中CSI处理单元的占用时间。
以下结合附图,详细说明本公开各实施例提供的技术方案。
图1为本公开的一个实施例确定信道状态信息CSI处理单元占用时间的方法的流程示意图,所述方法应用于终端设备,所述方法如下所述。
S102:根据CSI报告配置中的CSI报告类型,确定所述CSI处理单元的 占用时间。
在S102中,在波束测量的应用场景下,在确定CSI处理单元的占用时间时,可以根据CSI报告配置中的CSI报告类型,确定所述CSI处理单元的占用时间。
本公开实施例中,网络设备配置的CSI报告类型可以包括两种,一种是终端设备向网络设备上报的CSI信息为波束测量信息,另一种是终端设备向网络设备上报的CSI信息为无内容,且CSI-RS资源不用于跟踪参考信号(Tracking Reference Signal,TRS),即与该CSI报告配置关联的CSI资源配置中的CSI-RS资源集CSI-RS-ResourceSet的高层参数trs-Info没有被配置。其中,终端设备向网络设备上报的CSI信息为无内容,可以理解为终端设备不向网络设备上报波束测量信息。
所述波束测量信息可以包括SSB的资源编号对应的波束测量量,或CSI-RS的资源编号对应的波束测量量,所述波束测量量可以包括L1-RSRP,也可以包括L1-参考信号接收质量(L1-Reference Signal Receiving Quality,L1-RSRQ)以及L1-信号与干扰加噪声比(L1-Signal to Interference plus Noise Ratio,L1-SINR)中的至少一种。
终端设备向网络设备上报波束测量信息可以对应终端设备对网络设备的多个发送波束进行测量的应用场景,此时,终端设备需要向网络设备报告测量的发送波束信息。
终端设备向网络设备上报的波束测量信息为无内容且CSI-RS资源不用于TRS测量,可以对应终端设备对自身的多个发送波束进行测量的应用场景,此时,终端设备不需要向网络设备报告测量的接收波束信息。
在本公开的一个实施例中,当CSI报告类型为向网络设备上报波束测量信息时,确定CSI处理单元的占用时间,可以包括:
根据所述CSI报告的时域特征,确定所述CSI处理单元的占用时间。
本实施例中,当终端设备向网络设备上报的CSI信息为波束测量信息时,可以基于CSI报告的时域特证,确定CSI处理单元的占用时间。其中,当终端设备向网络设备上报的CSI信息为波束测量信息时,对应的CSI报告配置中的报告量可以设置为cri-RSRP、ssb-Index-RSRP。
CSI报告的时域特征可以包括两种,一种可以是周期或半持续,另一种可以是非周期,其中,当CSI报告的时域特征为周期或半持续时,可以是基于SSB资源的周期或半持续CSI报告,也可以是基于周期CSI-RS资源的周期或半持续CSI报告,还可以是基于半持续的CSI-RS资源的周期或半持续CSI报告;当CSI报告的时域特征是非周期时,可以是基于SSB资源的非周期CSI报告,也可以是基于周期CSI-RS资源的非周期CSI报告,还可以是基于半持续或非周期CSI-RS资源的非周期CSI报告,这里不做具体限定。
下面将分别针对CSI报告两种不同的时域特征,说明如何确定CSI处理单元的占用时间。
在一种实现方式中,当CSI报告的时域特征为周期或半持续时,确定CSI处理单元的占用时间,可以包括:
CSI处理单元的占用时间从CSI资源中第一个OFDM符号开始,到用于传输CSI报告的物理上行链路共享信道(Physical Uplink Shared Channel,PUSCH)或物理上行链路控制信道(Physical Uplink Control Channel,PUCCH)的最后一个OFDM符号为止。
所述CSI资源为距离所述PUSCH或所述PUCCH第一个OFDM符号之前的Z’个OFDM符号最近一次发送的CSI资源。
在一个实施例中,所述CSI资源可以包括一种资源,该一种资源可以包括所述CSI报告配置关联的一个CSI资源配置(CSI-ResourceConfig)中配置的至少一个SSB资源或至少一个CSI-RS资源。
在另一个实施例中,所述CSI资源也可以包括多种资源,该多种资源可以包括所述CSI报告配置关联的一个CSI资源配置中配置的至少一个SSB资源或至少一个CSI-RS资源,以及,所述CSI报告配置关联的另一个CSI资源配置中配置的至少一个干扰测量资源或至少一个接收的信号强度指示(Received Signal Strength Indication,RSSI)测量资源。
也就是说,所述CSI资源需要包含至少一个SSB资源或至少一个CSI-RS资源,在此基础上,还可以包括至少一个干扰测量资源或至少一个RSSI测量资源。其中,所述SSB资源或CSI-RS资源可以用于参考信号接收功率的测量,所述参考信号接收功率可以是L1-RSRP,还可以是L1-SINR对应的分子,所 述干扰测量资源可以用于噪声和干扰功率的测量,所述RSSI测量资源可以用于RSSI的测量。
需要说明的是,当所述CSI资源中包括一种资源时,所述CSI资源中第一个OFDM符号可以理解为至少一个SSB资源或至少一个CSI-RS资源中的第一个OFDM符号;当所述CSI资源中包括多种资源时,该多种资源为一次发送,所述CSI资源中第一个OFDM符号可以理解为该多种资源中最先发送的资源的第一个OFDM符号。
所述Z’可以理解为终端设备计算波束测量信息所需的OFDM符号数。
本公开实施例中,Z’可以通过表1确定的BR i得到。
表1
Figure PCTCN2019101974-appb-000001
为了便于理解CSI处理单元的占用时间,可以参考图2。
图2中,假设终端设备(对应上行)的子载波间隔和网络设备(对应下行)的子载波间隔不同。其中,每个小方块代表一个OFDM符号。
在下行链路的OFDM符号中,从左往右第2个至第5个OFDM符号为CSI资源的OFDM符号,该CSI资源为距离传输CSI报告的PUSCH或PUCCH第一个OFDM符号前的Z’个OFDM符号最近一次发送的CSI资源。
在上行链路的OFDM符号中,从右往左第2个和第3个OFDM符号为用于传输CSI报告的PUCCH或PUSCH的OFDM符号。
从图2中可以看出,CSI处理单元的占用时间从CSI资源的第一个OFDM符号开始,到用于PUSCH或PUCCH的最后一个OFDM符号为止。
总的来说,当终端设备向网络设备上报波束测量信息时,若CSI报告的 时域特征为周期或半持续,则CSI处理单元的占用时间从传输该CSI报告的PUSCH或PUCCH的第一个OFDM符号之前的Z’个OFDM符号时长的最近一次发送的CSI资源的第一个OFDM符号开始(如果存在),到传输该CSI报告的PUSCH或PUCCH的最后一个OFDM符号为止。
在另一种实现方式中,当CSI报告的时域特征为非周期时,确定CSI处理单元的占用时间,可以包括:
CSI处理单元的占用时间从触发CSI报告的物理下行链路控制信道(Physical Downlink Control Channel,PDCCH)之后的第一个OFDM符号开始,到传输CSI报告的PUSCH的最后一个OFDM符号为止。
触发CSI报告的PDCCH中可以包含下行控制信息(Downlink Control Information,DCI),网络设备可以通过DCI中的CSI请求字段(CSI request field)触发CSI报告。
为了便于理解CSI处理单元的占用时间,可以参见图3。
图3中,假设终端设备的子载波间隔和网络设备的子载波间隔不同,每个小方块代表一个OFDM符号。
在下行链路的OFDM符号中,从左往右第2个至第5个OFDM符号为CSI资源的OFDM符号,第7个和第8个OFDM符号为用于触发CSI报告的PDCCH的OFDM符号。
在上行链路的OFDM符号中,从右往左第2个和第3个OFDM符号可以是用于传输CSI报告的PUSCH的OFDM符号。
从图3中可以看出,CSI处理单元的占用时间从触发该CSI报告的PDCCH之后的第一个OFDM符号开始,到传输该CSI报告的PUSCH的最后一个OFDM符号为止。
需要说明的是,当CSI报告的时域特征为基于非周期CSI资源的非周期时,当CSI处理单元的占用时间满足以下条件时,才会更新CSI报告。
第一:如果考虑定时提前量,则传输CSI报告的PUSCH或PUCCH的第一个上行OFDM符号不早于第Z ref个OFDM符号,且不早于第Z’ ref个OFDM符号时;
第二:所述CSI资源的最后一个OFDM符号与传输CSI报告的PUSCH或 PUCCH的第一个OFDM符号之间的符号数大于等于Z’,且,从触发CSI报告的PDCCH的第一个OFDM符号到用于传输CSI报告的PUSCH或PUCCH的第一个OFDM符号之间的符号数大于等于Z。
也就是说,在能够保证计算得到波束测量信息的情况下,才会更新CSI报告。
Z ref可以定义为循环前缀(Cyclic Prefix,CP)的起始时刻在用于触发CSI报告的PDCCH最后一个OFDM符号之后T=(Z)(2048+144)κ2 T c(秒)的下一个上行OFDM符号。
当CSI报告为基于非周期CSI-RS资源的CSI报告时,Z’ ref可以定义为CP的起始时刻在信道测量的非周期CSI-RS资源、干扰测量的非周期CSI-IM(CSI Interference Measurement)资源以及干扰测量的非周期NZP(Non-zero Power,非零功率)CSI-RS资源三者中最后一个OFDM符号后T′=(Z′)(2048+144)κ2 T′ c(秒)的下一个上行OFDM符号。
为了便于理解Z ref和Z’ ref,可以参见图4。
图4中,假设终端设备和网络设备使用的子载波间隔相同,则,Z ref可以表示为PDCCH的最后一个OFDM符号的T时长后的第一个OFDM符号,Z’ ref可以表示为CSI-RS资源以及CSI-IM资源中最后一个OFDM符号的T’时长后的第一个OFDM符号。
Z’可以表示计算波束测量信息的OFDM符号数,与上述第一种实现方式中记载的Z’相同。
Z与Z’相关,其中,Z’可以通过上述记载的表1确定RB i得到,Z与Z’的差值可以为固定值,该固定值可以与相关技术中规定的CSI报告中的Z 1和Z 1’的差值相同,或与Z 2和Z 2’的差值相同。
如下表2和表3所示。在表2和表3中,μ=1,2,3,4分别对应于子载波间隔15KHz,30KHz,60KHz,120kHz。其中,表2适用于低时延要求的应用场景,表3适用于高时延要求的应用场景。

表3

基于上述表2和表3,在已知Z’的情况下,可以确定得到相应的Z。
例如,在低时延30KHz子载波间隔的场景下,若基于上述表1确定Z’为8,则根据表2中与30KHz子载波间隔对应的Z 1和Z 1’,可以得到Z=Z 1-Z 1’+Z’=10。

根据所述CSI报告的时域特征以及物理上行链路资源的配置情况,确定所述CSI处理单元的占用时间,所述物理上行链路资源为PUCCH资源或PUSCH资源。
本实施例中,可以基于CSI报告的时域特征以及物理上行链路资源(PUCCH资源或PUSCH资源)的配置情况,确定CSI处理单元的占用时间。 其中,本实施例对应的CSI报告配置中的报告量可以设置为none。
当终端设备向网络设备上报的CSI信息为无内容时,CSI报告的时域特征也可以包括两种,一种可以是周期或半持续,另一种可以是非周期,其中,当CSI报告的时域特征是周期或半持续时,可以是基于SSB资源的周期或半持续CSI报告,也可以是基于周期CSI-RS资源的周期或半持续CSI报告,还可以是基于半持续的CSI-RS资源的半持续CSI报告;当CSI报告的时域特征是非周期时,可以是基于SSB资源的非周期CSI报告,也可以是基于周期或半持续CSI-RS资源的非周期CSI报告,还可以是基于非周期CSI-RS资源的非周期CSI报告,这里不做具体限定。
所述物理上行链路资源的配置情况可以包括两种,一种是网络设备已为终端设备配置物理上行链路资源,即存在PUCCH资源或PUSCH资源,另一种是网络设备没有为终端设备配置物理上行链路资源,即不存在PUCCH资源和PUSCH资源,其中,当网络设备为终端设备配置的物理上行链路资源为0时,可以理解为网络设备没有为终端设备配置物理上行链路资源。
下面将分别针对CSI报告两种不同的时域特征以及两种不同的物理上行链路资源配置情况,说明如何确定CSI报告的占用时间。
在第一种实现方式中,当CSI报告的时域特征为周期或半持续,且网络设备已配置物理上行链路资源时,确定CSI处理单元的占用时间,可以包括:
CSI处理单元的占用时间从CSI资源中第一个OFDM符号开始,到配置的所述CSI报告的周期或半持续PUCCH或PUSCH的第(1+x)个OFDM符号为止;或,

所述CSI资源可以为距离所述PUSCH或所述PUCCH第一个OFDM符号之前的Z’个OFDM符号最近一次发送的至少一个CSI资源中最早的CSI资源。

所述Z’与上述第一个实施例中记载的Z’相同,即为计算波束测量信息所需的OFDM符号数。所述Z’具体可以根据上述记载的表1确定的BR i得到,这里也不再重复说明。
所述x为整数,其中,x=-1表示配置该CSI报告的PUSCH或PUCCH第一个OFDM符号的前一个OFDM符号,CSI处理单元的占用时间从CSI资源中第一个OFDM符号开始,到配置的CSI报告的周期或半持续PUCCH或PUSCH的前一个OFDM符号为止。
x=0表示配置该CSI报告的PUSCH或PUCCH的第一个OFDM符号,CSI处理单元的占用时间从CSI资源中第一个OFDM符号开始,到配置的CSI报告的周期或半持续PUCCH或PUSCH的第一个OFDM符号为止。
x=1表示配置该CSI报告的PUSCH或PUCCH第一个OFDM符号的后一个OFDM符号,CSI处理单元的占用时间从CSI资源中第一个OFDM符号开始,到配置的CSI报告的周期或半持续PUCCH或PUSCH第一个OFDM符号的后一个OFDM符号为止。
……,以此类推。
为了便于理解CSI处理单元的占用时间,可以以x=-1为例进行说明。请参考图5。
图5中,假设终端设备的子载波间隔和网络设备的子载波间隔不同,每个小方块代表一个OFDM符号。
在下行链路的OFDM符号中,从左往右第2个至第5个OFDM符号为CSI资源的OFDM符号,该CSI资源距离配置CSI报告的PUSCH或PUCCH第一个OFDM符号的前Z’个OFDM符号最近一次发送的CSI资源,第7个和第8个OFDM符号表示用于触发CSI报告的PDCCH的OFDM符号。
在上行链路的OFDM符号中,从右往左第2个和第3个OFDM符号为用于配置CSI报告的PUCCH或PUSCH的OFDM符号。
从图5中可以看出,CSI处理单元的占用时间从CSI资源的第一个OFDM符号开始,到配置CSI报告的周期或半持续PUCCH或PUSCH的前一个OFDM符号为止。
总的来说,当CSI报告为周期或半持续,且网络设备已配置物理上行链路资源时,CSI处理单元的占用时间从配置的周期或半持续PUSCH/PUCCH第一个符号之前的Z’个OFDM符号时长的最近一次发送的CSI资源的第一个OFDM符号开始(如果存在),到配置该CSI报告的周期或半持续PUSCH/PUCCH第一个OFDM符号+x个OFDM符号位置,或到配置的CSI报告的周期或半持续PUCCH/PUSCH的最后一个OFDM符号为止,其中,x为整数。
所述CSI资源还可以是不晚于所述CSI报告对应的CSI参考资源的最近一次发送的至少一个CSI资源中的最早的CSI资源。其中,所述CSI参考资源可以是相关技术的标准中定义的参考资源,也可以与周期或半持续发送的CSI-RS资源有关。当所述CSI参考资源与周期或半持续发送的CSI-RS资源有关时,所述CSI参考资源可以是每次发送的至少一个CSI-RS资源中第一个CSI-RS资源的第一个OFDM符号,或每次发送的至少一个CSI-RS资源中最后一个CSI-RS资源的最后一个OFDM符号。
为了便于理解,可以参见图6。

从图6可以看出,CSI处理单元的占用时间从CSI资源的第一个OFDM符号开始,到配置的CSI报告的的PUCCH或PUSCH的最后一个OFDM符号为止。其中,所述CSI资源为不晚于CSI报告对应的CSI参考资源的最近一次发送的CSI资源,所述CSI参考资源定义与每次发送的CSI-RS资源有关。
在第二种实现方式中,当CSI报告的时域特征为周期或半持续,且网络设备已配置或没有配置所述物理上行链路资源时,确定CSI处理单元的占用时间,可以包括:
CSI处理单元的占用时间从CSI资源的第一个OFDM符号开始,到所述CSI资源的最后一个OFDM符号之后的(Z’+y)个OFDM符号为止。

所述y为大于等于0的整数,其中,y=0表示CSI资源最后一个OFDM符号后的Z’个OFDM符号,CSI处理单元的占用时间从CSI资源中第一个OFDM符号开始,到CSI资源中最后一个OFDM符号之后的Z’个OFDM符号为止。
y=1表示CSI资源最后一个OFDM符号后的(Z’+1)个OFDM符号,CSI处理单元的占用时间从CSI资源中第一个OFDM符号开始,到CSI资源中最后一个OFDM符号之后的(Z’+1)个OFDM符号为止。
……,以此类推。
为了便于理解CSI处理单元的占用时间,可以以y=0为例进行说明。请参考图7。
图7中,假设终端设备的子载波间隔和网络设备的子载波间隔不同,每个小方块代表一个OFDM符号。
在下行链路的OFDM符号中,从左往右第2个至第5个OFDM符号为一次发送的CSI资源的OFDM符号。

从图7中可以看出,CSI处理单元的占用时间从CSI资源的第一个OFDM符号开始,到该CSI资源最后一个OFDM符号之后的Z’个OFDM符号为止。
总的来说,当CSI报告为周期或半持续,且网络设备已配置或没有配置物理上行链路资源时,CSI处理单元的占用时间从每次发送的CSI资源的第一个OFDM符号开始,到该CSI资源的最后一个OFDM符号之后的Z’个OFDM符号+y个OFDM符号为止,与配置CSI报告的物理上行链路资源(即PUCCH资源或PUSCH资源)无关。
所述CSI资源还可以是不晚于所述CSI报告对应的CSI参考资源的最近 一次发送的至少一个CSI资源中最早的CSI资源。所述CSI参考资源与上述记载的CSI参考资源相同,这里不再重复说明。
为了便于理解,可以参见图8。
图8中,假设终端设备的子载波间隔和网络设备的子载波间隔不同,每个小方块代表一个OFDM符号。
从图8可以看出,CSI处理单元的占用时间从CSI资源的第一个OFDM符号开始,到所述CSI资源的最后一个符号之后的Z’个符号为止,其中y=0。所述CSI资源为不晚于所述CSI报告对应的CSI参考资源的最近一次发送的CSI资源,所述CSI参考资源为相关技术的标准中定义的CSI参考资源。
需要说明的是,在上述两种实现方式中,即当CSI报告的时域特征为周期或半持续时,CSI资源的测量周期和时隙偏移,可以与所述CSI报告资源的发送周期和时隙偏移保持一致。
所述CSI资源需要包括与所述CSI报告配置关联的CSI资源配置中的至少一个SSB资源或至少一个CSI-RS资源,在此基础上,还可以包括与所述CSI报告配置关联的CSI资源配置中的至少一个干扰测量资源或至少一个RSSI测量资源。网络设备在为终端设备配置与CSI报告配置相关的CSI资源后,终端设备在进行波束测量时,对CSI资源的测量周期和时隙偏移,可以与网络设备配置CSI资源的发送周期和时隙偏移相同,无需额外规定终端设备对CSI资源的测量周期和时隙偏移。

所述Z与上述第一个实施例中记载的Z相同,即Z与所述Z’相关,Z可以基于Z’,结合上述记载的表2和表3确定得到。
所述n为大于等于0的整数。
当CSI处理单元的占用时间从触发所述CSI报告的PDCCH之后的第一个OFDM符号开始,到第一OFDM符号和第二OFDM符号中其中一个为止时,为了便于理解,可以参考图9。
图9中,假设终端设备的子载波间隔和网络设备的子载波间隔不同,每个小方块代表一个OFDM符号。
在下行链路的OFDM符号中,从左往右第2个至第5个OFDM符号为一次发送的CSI资源的OFDM符号。

需要说明的是,上述各实施例中,触发的上报波束测量信息或上报的CSI信息为无内容且CSI-RS资源不用于TRS测量的非周期CSI报告均为触发一个非周期CSI报告。当一个DCI触发多个非周期CSI报告,且其中一个CSI报告为上报波束测量信息或上报的CSI信息为无内容且CSI-RS资源不用于TRS测量的非周期CSI报告时,按相关技术中的触发多个非周期CSI报告的规则确定Z或Z’,即Z=max(Z(m)),Z’=max(Z’(m))。
在本公开的一个特殊实施例中,当所述CSI报告类型为向所述网络设备上报的波束测量信息为无内容且CSI-RS资源不用于TRS测量时,还可以确定 不占用CSI处理单元,即CSI处理单元的占用时间为零。在这种情况下,可以使用终端设备中的其他处理单元计算CSI。
在本公开实施例提供的技术方案,在波束管理中,在确定终端设备中CSI处理单元的占用时间时,可以根据CSI报告配置中的CSI报告类型,确定所述CSI处理单元的占用时间,所述CSI报告类型包括所述终端设备向网络设备上报的CSI信息为波束测量信息,或向所述网络设备上报的CSI信息为无内容且信道状态信息参考信号CSI-RS资源不用于跟踪参考信号TRS测量。这样,在波束管理中,在向网络设备上报的CSI信息为波束测量信息以及上报的CSI信息为无内容且CSI-RS资源不用于TRS测量两种应用场景下,确定终端设备中CSI处理单元的占用时间时,可以基于本公开实施例提供的技术方案,明确CSI处理单元的占用时间,终端设备和网络设备的行为更加清晰。

为了便于理解,可以参见图12和图13。
在图12中,CSI处理单元的占用时间可以从CSI资源(每次发送CSI资源配置中的CSI资源集的一组CSI资源)中第一个OFDM符号开始,到这次发送的最后一个CSI-RS资源的最后一个OFDM符号之后的Z’个OFDM符号为止,其中y=0,Z’的定义可以与上述图1所示实施例中记载的Z’相同,但是,但在本公开实施例中,Z’是由以下表4和表5确定得到。

需要说明的是,终端设备进行的无CSI报告的波束测量的周期与时隙偏 移,可以与CSI资源配置中配置的周期CSI-RS或半持续CSI-RS的周期与时隙偏移一致,即每次发送CSI资源配置中的CSI-RS资源集的一组CSI-RS资源且重复设置为“on”,UE都可以进行一次无CSI报告的波束测量CSI报告的波束测量周期和时隙偏移,与周期或半持续的所述CSI-RS资源的发送周期和时隙偏移一致。
本公开实施例提供的技术方案,在波束管理中,在没有配置CSI报告配置的应用场景下,在确定终端设备中CSI处理单元的占用时间时,可以基于本公开实施例提供的技术方案,明确CSI处理单元的占用时间,终端设备和网络设备的行为更加清晰。

在根据小区级配置的目标接收功率与终端设备特定的目标接收功率确定PUCCH目标接收功率时,可以将所述小区级配置的目标接收功率与所述终端设备特定的目标接收功率的和作为所述PUCCH的目标接收功率。
本公开实施例中,P O_UE_PUCCH的取值可以是0;P O_NOMINAL_PUCCH的取值可以是高层配置参数小区级目标接收功率p0-nominal的取值。
在一种实现方式中,若高层未配置p0-nominal,P O_NOMINAL_PUCCH的取值可以默认为0;
在一种实现方式中,若高层未配置p0-nominal,P O_NOMINAL_PUCCH的取值可以是前导目标接收功率和消息3与所述前导目标接收功率的偏移量之和,具体可以由如下公式表示:
P O_NOMINAL_PUSCH,f,c(0)=P O_PREPREAMBLE_Msg3
其中,P O_PRE表示前导目标接收功率preambleReceivedTargetPower,Δ PREAMBLE_Msg3表示消息3偏移量msg3-DeltaPreamble;preambleReceivedTargetPower和msg3-DeltaPreamble均由高层配置。
本公开实施例,可以在终端设备成功接收到来自网络设备的链路恢复响应之后,至终端设备成功接收到PUCCH空间相关信息MAC CE激活或RRC重配置之前的时间内,当PUCCH传输使用的空间滤波参数同PRACH相同,且PRACH为基于竞争的PRACH时,能够根据小区级配置的目标接收功率与终端设备特定的目标接收功率,明确PUCCH的目标接收功率。
