Description

信道状态信息的报告方法、装置及终端
交叉引用
本发明要求在2020年10月20日提交中国专利局、申请号为202011126978.4、发明名称为“反馈信息传输方法、终端及网络设备”的中国专利申请的优先权,该申请的全部内容通过引用结合在本发明中。
技术领域
本申请属于无线通信技术领域,具体涉及一种信道状态信息的报告方法、装置及终端。
背景技术
5G新空口(NewRadio,NR)通信系统中提出了多发送接收点/多天线面板(multi-TRP/multi-Panel)的通信场景,用以增强传输的可靠性和吞吐量性能,例如,终端可以接收来自于多个TRP的相同数据或不同数据。
其中,对于多TRP间多TRP/panel的传输场景,如果采用基于组(group based)的波束报告方案,虽能保证信道状态信息(Channel State Information,CSI)报告中的两个CSI-RS资源指示(CSI-Reference Signal Resource Indicator,CRI)/同步信号块资源指示(Synchronization Signal and PBCH blockResource Indicator,SSB RI)所指示的发送波束能被终端同时接收,但由于该方案未对TRP侧能否同时发送进行限制,从而可能出现CSI报告的两个CRI/SSBRI来自于同一个TRP,导致多TRP不能同时发送。如果采用非基于组的波束报告方案,终端会根据多个面板的测量结果,选择其中n(n=1/2/4)个质量最佳的波束及其对应的层1-参考信号接收功率(Layer 1 reference signal received power,L1-RSRP)在每个CSI报告中进行上报,但由于未限制质量最佳的波束是否需对应不同的接收面板,因此非基于组的波束报告方案不能保证上报的波束能被终端同时接收。
因此,无论是基于组的波束报告方案,还是非基于组的波束报告方案,均无法实现多TRP间多TRP/panel的同时传输。

图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括终端11和网络侧设备12。其中,终端11也可以称作终端设备或者用户终端(User Equipment,UE),终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant,PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer,UMPC)、移动上网装置(Mobile Internet  Device,MID)、可穿戴式设备(Wearable Device)或车载设备(VUE)、行人终端(PUE)等终端侧设备,可穿戴式设备包括:手环、耳机、眼镜等。需要说明的是,在本申请实施例并不限定终端11的具体类型。网络侧设备12可以是基站或核心网,其中,基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station,BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set,BSS)、扩展服务集(Extended Service Set,ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、WLAN接入点、WiFi节点、TRP或所述领域中其他某个合适的术语,只要达到相同的技术效果,所述基站不限于特定技术词汇,需要说明的是,在本申请实施例中仅以NR系统中的基站为例,但是并不限定基站的具体类型。
下面结合附图,通过具体的实施例及其应用场景对本申请实施例提供的技术方案进行详细地说明。
如图2所示,为本申请一示例性实施例提供的信道状态信息的报告方法200的流程示意图,该方法200可以应用但不限于终端,具体可由安装于终端中的硬件和/或软件执行。所述方法200至少包括以下步骤。
S210,从各目标资源组中选取一个或多个目标资源。
其中,所述目标资源至少可以包括CSI-RS资源和/或SSB资源等。所述CSI-RS资源包括周期性CSI-RS、非周期性CSI-RS资源、半持续CSI-RS资源中的至少一个,所述SSB资源为周期性资源。
一种实现方式中,各个目标资源组的时域特性可以为以下(1)-(5)中的任一种。
(1)各组的CSI-RS资源或SSB资源均为周期性。
(2)部分组的CSI-RS资源配置为周期性或SS/PBCH块资源,另一部分组的CSI-RS资源配置为半持续性。
(3)部分组的CSI-RS资源配置为周期性或SS/PBCH块资源,另一部分组CSI-RS资源配置为非周期性。
(4)各组的CSI-RS资源都配置为半持续性。
(5)部分组CSI-RS资源配置为半持续性,另一部分组的CSI-RS资源配置为非周期性。
各所述目标资源组分别对应不同的目标TRP,所述目标TRP为所述终端上报CSI报告的TRP。本实施例中,通过将目标资源组与目标TRP对应,能够保证CSI报告中反馈的目标资源(如CRI、SSB RI)所对应的波束能被多个目标TRP同时发送,提高多TRP间的同时传输性能。
可以理解的是,在多-下行控制信息(Multiply-Downlink Control Information,Multi-DCI)场景下,终端可根据控制资源集索引(CORESETPoolindex)确定各目标TRP所关联的目标资源组。在单-DCI(S-DCI)的场景下,由于没有CORESETPoolindex的定义,因此,终端只知道网络侧设备配置了多个目标资源组,并不知道目标资源组与目标TRP之间的对应关系,但考虑到终端配备了多个接收面板,因此,终端依旧可同时接收多个CSI-RS。
进一步,所述目标资源组可根据接收到的资源指示信息确定。一种实现方式中,网络侧设备可配置N个目标资源,并通过所述资源指示信息指示M组目标资源组给所述终端,N≥M。其中,每个所述目标资源组可包括预设数量个目标资源,所述预设数量为N/M的向上取整,或者,所述预设数量为N/M的向下取整,其中,N为网络侧设备配置的目标资源的总数量,M为所述目标资源组的总数量。
本实施例中,所述资源指示信息可通过无线资源控制(Radio Resource Control,RRC)、媒体访问控制控制单元(Medium Access Control-Control Element,MAC CE)或下行控制信息(Downlink Control Information,DCI)传输。
S220,根据各所述目标资源,确定第一信道状态信息CSI报告。
其中,所述第一CSI报告中可以包括有CSI-RS资源指示(CSI-RSResource  Indicator,CRI)、SSB资源指示(SSBRI)、层1-参考信号接收功率(L1-RSRP)、层1-信号加干扰噪声比(L1-SINR)、预编码矩阵秩指示(Precoding Matrix Indicator,PMI)、信道质量指示(Channel Quality Indicator,CQI)、秩指示(Rank Indicator,RI)中的至少一项。另外,需要理解的是,后续实施例中提及的波束报告为CSI报告的一种格式,与所述CSI报告类似,所述波束报告中也可包含但限于CRI、SSBRI、L1-RSRP、L1-SINR等。
S230,反馈所述第一CSI报告。
其中,如果所述终端具有O个接收面板,那么,所述终端能同时接收O个目标参考信号。相应的,在根据各所述目标资源确定的第一CSI报告的情况下,所述第一CSI报告可以包括多个目标资源,也就是,终端可反馈多个目标资源,如CRI/SSB RI等,一个目标资源对应一个目标资源组,从而确保所述终端能够同时接收多个CSI-RS参考信号或/和SSB同步信号等。
示例性的,如图3所示,为终端向两(K=2)个目标TRP反馈CSI报告的原理图,其中包括配置两个CSI report setting或一个CSI report setting关联两个CSI上报的情况。如图3所示,假设网络侧设备共配置4个目标资源,如CSI-RS资源,即N=4,将4个CSI-RS资源分为两个目标资源组,即M=2。在Multi-DCI场景下,终端可知CORESETPoolindex=0(TRP1)所关联的目标资源组1包含CSI-RS#1和CSI-RS#2,CORESETPoolindex=1(TRP2)所关联的目标资源组2包含CSI-RS#3和CSI-RS#4;在S-DCI的场景下,无CORESETPoolindex的定义,终端只知道网络侧设备配置了两个目标资源组,不知道每个目标资源组具体与哪个目标TRP关联。但由于终端配备了两个接收面板,即O=2,因此终端可同时接收两个CSI-RS。
在模式一(即前述的预定模式)下,即配置两个CSI report setting且每个CSI report setting都配置为未使能基于组的波束报告(groupBasedBeamReporting=disabled),其中,每个CSI report setting仅关联一个目标资源组,而这个目标资源组中的目标资源属于某个目标TRP。在每 一个CSI报告发起后,终端会从与其关联的目标资源组中分别选择1或2个CRI,以确定CSI报告(即第一CSI报告),并向其对应的目标TRP进行上报。由于终端向某个目标TRP上报的CRI都对应于该TRP的某个CSI-RS资源,因此向不同目标TRP上报的CRI满足同时发送的条件。
在模式二下,即配置一个或两个CSI report setting且每个CSI report setting都配置为使能基于组的波束报告(groupBasedBeamReporting=enabled),其中,每个CSI report setting关联多个目标资源组。在每个CSI报告发起后,终端分别从目标资源组1和目标资源组2选择1个CRI,以确定CSI报告(即第一CSI报告),并向其对应的目标TRP进行上报。由于终端选择的波束对中的每一个波束都来自于不同的目标TRP且groupBasedBeamReporting=enabled,因此该波束对可被两个目标TRP同时发送,被配置多个面板的UE同时接收。
本实施例给出的方法200中,终端根据资源指示信息确定目标资源组,进而从每个目标资源组选取一个或多个目标资源,以实现CSI报告的反馈,由此,本实施例通过资源配置的方式,使得终端向目标TRP上报的CSI报告中的目标资源对应于目标TRP的CSI-RS资源等,从而有效的增强了多TRP间多TRP/panel的同时传输能力,如终端的同时接收能力、多TRP的同时发送能力等。
如图4所示,为本申请一示例性实施例提供的信道状态信息的报告方法400的流程示意图,该方法400可以应用但不限于终端,具体可由安装于终端中的硬件和/或软件执行。所述方法400至少包括以下步骤。

(1)基于第二CSI报告中的CRI,按照一对一配对方式从各目标资源组 中选取一个或多个目标资源。
其中,与所述第一CSI报告类似,所述第二CSI报告也是基于所述目标资源组确定的,所述第二CSI报告的反馈时间早于所述第一CSI报告的反馈时间。所述一对一配对方式包括对应位置配对和交叉位置配对。
(2)基于第二CSI报告中的CRI,按照一对多配对方式从各目标资源组中选取一个或多个目标资源。
(3)基于第二CSI报告中的CRI,按照完全配对方式从各目标资源组中选取一个或多个目标资源。
其中,所述预定模式(也即前述方法200中所述的模式一)包括如下方式的组合:配置有一个或多个CSI报告配置;每个所述CSI报告配置(CSI report setting)配置一个或多个上行传输资源(如PUCCH/PUSCH资源);每个所述CSI报告配置均为未使能基于组的波束报告(也就是,groupBasedBeamReporting=disabled);每个所述CSI报告配置分别关联一个所述目标资源组。
S420,根据各所述目标资源,确定第一信道状态信息CSI报告。
其中,S420中的实现过程除可参照前述S220中的详细描述之外,一种可能的实现方式中,在所述第一CSI报告中包括所述终端选择、且需要上报的目标波束的情况下,所述第一CSI报告需满足以下条件(1)-(3)中的至少一个。
(1)将相互关联的所述第一CSI报告和第二CSI报告中的CRI进行组合获得的CRI组合中,至少存在一个CRI组合被所述终端同时接收。
其中,与所述第一CSI报告类似,所述第二CSI报告是基于所述目标资源组确定的,且所述第二CSI报告的反馈时间早于所述第一CSI报告的反馈时间。一种实现方式中,对CSI报告进行相互关联的方式可以包括:在网络侧设备配置CSI报告时,通过设置同一ID进行关联。
本实施例中,在对第一CSI报告和第二CSI报告中的CRI进行组合时, 可采用如S410中所述的一对一配对方式、一对多配对方式或完全配对方式,本实施例对此不做限制。
(2)所述第一CSI报告为基本波束上报。
(3)在所述第一CSI报告为非基本波束上报的情况下,所述第一CSI报告中的CRI与预定基本波束上报中的CRI被所述终端同时接收,其中,所述预定基本波束可以根据实际需求进行设定,例如,在所述第一CSI报告为非基本波束上报的情况下,所述预定基本波束可以是所述第二CSI报告。
另外,在前述(1)-(3)中的实现方式中,所述目标波束可根据以下(1)和(2)中的至少一项确定。
(1)第二CSI报告中的波束。
(2)预配置的上行传输或下行传输对应的波束。其中,所述上行传输可以包括物理上行共享信道(PUSCH)或物理上行控制信道(PUCCH),所述下行传输可以包括物理下行共享信道(PDSCH)或物理下行控制信道(PDCCH)。
另一种可能的实现方式中,在所述终端完成对第二CSI报告上报、且所述第二CSI报告中包括的多个CRI被同时接收的情况下,与所述第二CSI报告关联的第一CSI报告满足以下条件(1)-(3)中的至少一项。
(1)所述第一CSI报告中包括的CRI,与所述第二CSI报告中包括的CRI至少部分相同。
(2)在所述第一CSI报告和所述第二CSI报告中不存在相同的CRI的情况下,所述第一CSI报告中的指定CRI与所述第二CSI报告中的指定CRI被所述终端同时接收。
(3)所述第一CSI报告中包括的多个CRI被终端同时接收。
基于前述实现方式,在所述第一CSI报告中包括的多个CRI被同时接收的情况下,或者,在对所述第一CSI报告中的CRI与第二CSI报告中的CRI进行组合时,存在被同时接收的CRI组合的情况下,所述第一CSI报告中包 括的指定内容根据预定传输方案假设进行确定,所述指定内容为所述第一CSI报告中CRI、PMI、RI、CQI中的一个或多个。
其中,所述预定传输方案假设包括非相干联合传输(NCJT)或动态传输点选择(DPS)。
本实施例中,所述第一CSI报告中包括的指定内容根据预定传输方案假设进行确定的确定过程,包括:根据所述第一CSI报告中的第一指定内容,和/或所述第二CSI报告中的第一指定内容,确定目标内容,其中,所述第一指定内容为CRI、PMI、RI、CQI中的一个或多个;将所述第一CSI报告中的第一指定内容替换为所述目标内容。
例如,假设预定传输方案假设为NCJT,在此情况下,所述第一CSI报告中包括第一指定内容CRI为A1,CQI为B1,与所述第一CSI报告关联的第二CSI报告中包括第一指定内容CRI为A2,CQI为B2,那么根据A1和A2计算得到的目标内容联合CQI为B3,那么可以将所述第一CSI报告中的B1替换为B3,反馈替换后的第一CSI报告。
本实施例中,所述预定传输方案假设可以通过如下方式(1)-(3)中的任一项进行指示。

(2)协议约定。

其中,所述预定波束可以根据需求设定,例如,可以选择L1-RSRP值高的波束作为预定波束。一种实现方式中,针对向多个TRP上报的波束不满足被终端同时接收的情况,可定义终端行为如下:对于部分能同时接收的波束正常接收其承载的数据,而对于不能同时接收的部分波束,终端可接收预定波束承载的数据。
基于前述方法400的描述,下面结合不同的示例对方法400的实现过程进行进一步介绍。
示例性1
假设在模式一(即前述的预定模式)下,网络侧配置的目标资源(如CSI-RS资源)总数为6,共分成两个目标资源组,每个目标资源组包含3个CSI-RS资源,当CSI报告发起时,终端可选择2个CRI进行上报。
结合参阅表1、图5a、图5b所示(虚线箭头表示CSI报告的发起,实线箭头表示CSI-RS信号),终端在时间t1~t2之间从左向右移动。在t1时刻,Report#1发起时,终端侧根据测量结果从Report#1关联的CSI resource setting中所有CSI-RS资源(CSI-RS#1~3)中选择两个CRI向TRP1进行上报,如表1中第一行所示选择了CRI#1和CRI#2。在TRP1接收到CSI报告时,可以根据一定规则(如根据L1-RSRP值进行选择)在两个CRI中选择其余一个作为PDSCH传输的发送波束。

在t2时刻,Report#2发起时,终端侧根据测量结果从Report#2关联的CSI resource setting中所有CSI-RS资源(CSI-RS#4~6)中选择两个CRI向TRP2进行上报,在对关联的两个CSI报告进行波束选择的过程中,终端需选择出满足下列条件中的波束:
关联的CSI报告1(如前述的第二CSI报告)中所选择的CRI与关联的CSI报告2(如前述的第一CSI报告)中选择的CRI组合(如一对一配对方式、一对多配对方式、完全配对方式),至少存在一个CRI组合能被终端同时接收。
结合表1,假设终端在Report#1发起后根据上述条件确定了上报波束CRI#1和CRI#2。在Report#2发起时,终端会根据Report#1中的波束内容从CRI#4~6中选择出与CRI#1、CRI#2两两组合后,存在多个组合满足同时接收的两个CRI。结合表1中的内容,波束对应的具体关系可举例如下:
(1)当采用一对一配对方式中的对应位置配对方式时,可上报的波束为(CRI#5,CRI#6)或(CRI#5,CRI#4)。
(2)当采用一对一交叉位置配对方式时,可上报的波束为(CRI#6,CRI#5)或(CRI#4,CRI#5)。
(3)当采用一对多的配对方式时,对于report1中的CRI#2,report2可按照一定规则从CRI#6、CRI#5、CRI#4中挑出两个进行上报,比如选择 L1-RSRP较高的CRI;对于report1中的CRI#1,report2则只会上报CRI#5。
(4)当采用完全匹配时,即任意组合均可实现同时传输时,没有满足前述上报条件的波束。
应注意,在前述方式中,如果存在多个满足对应关系的波束组合时,可根据一定规则再次进行选择,比如选择L1-RSRP高的组合。
示例2
假设在模式二(可参阅方法200中的对应描述)下,在图6a中,假设TRP1和TRP2之间的链路是理想回传线路,每次CSI报告的波束内容都能被终端同时接收且来自于不同的TRP,而TRP间可通过理想回传线路共享波束报告,从而其可实现多TRP的同时传输。但在TRP间的非理想回传线路,在TRP间不能及时共享波束信息的情况下,通常采用向两个TRP分别进行波束上报。本示例2可提高向两个TRP分别上报的波束满足同时接收的概率,从而增强非理想回传线路下多TRP的同时传输能力。

结合图6a、图6b和表2,在t1时刻,Report#1发起时,终端根据测量结果分别从每个CSI resource setting关联的所有CSI-RS资源中选择一个CRI,共组成两个可同时被终端接收的波束对,随后终端根据每组波束对的测量结果选择出(CRI#1和CRI#3)向TRP1进行上报,如表2中第一行所示。在 TRP1接收到CSI报告时,根据CRI所属的CSI-RS资源组,TRP1可以确定属于自身的CSI-RS资源指示为CRI#1和发送波束。
在t2时刻,Report#2发起时,终端测量统计得到4个可同时被终端接收的波束对,随后终端需要选择出至少满足下列条件中的一个的波束对(CRI#x,CRI#y):
(CRI#x,CRI#y)与(CRI#1,CRI#3)组合,4个组合中(CRI#x,CRI#1)、(CRI#x,CRI#3)、(CRI#1,CRI#y)、(CRI#3,CRI#y)至少存在一个能被终端同时接收。
经过前述选择:
(1)若无满足条件的波束对,终端会根据波束对的测量结果从所有满足能被终端同时接收的波束对(即表2中的4对波束)中选择一对向TRP2上报,但在这种情况下,无法保证多个TRP的发送波束能被终端同时接收。对此,对于部分能同时接收的波束终端正常接收其承载的数据,而对于不能同时接收的部分波束,终端可根据一定规则选择只对其中一个波束承载的数据进行接收,比如选择L1-RSRP值高的。
(2)若存在满足条件的波束对且仅有一对时,终端会将其进行上报。
(3)若存在多对满足条件的波束,终端会根据一定规则再次进行选择,比如根据测量结果(如L1-RSRP)或满足同时接收的组合数,选择出一对波束进行上报。在表2中的第2行,终端最终选择了(CRI#2,CRI#4)进行上报。TRP2接收到report2后,TRP2可根据资源配置得知属于自身的CSI-RS资源指示为CRI#4,由于(CRI#1和CRI#4)在当前报告的测量中显示能被终端同时接收,因此TRP1和TRP2在当下便可实现同时传输。但是若report2选择了(CRI#2,CRI#3)向TRP2报告,会导致TRP1和TRP2分别对应的CRI#1和CRI#3在当前可能无法被终端同时接收。
应注意,后续report的操作方式与Report#2相同,按照相同的波束选择条件与上报机制进行即可,在此不再赘述。
示例3
示例3中的CSI-RS资源、资源分组和报告配置方法可参照示例2中的描述(模式一)。
参阅图7a,在multi-DCI的场景下,网络侧设备可以与终端提前约定,定义与CORESETPoolindex=0关联的TRP为基本TRP,向基本TRP进行的波束上报为基本波束上报,即在本实例中TRP1为基本TRP,也就是,向TRP1上报的波束报告为基本波束报告。因此,结合参阅表3,在t1时刻,Report#1上报的(CRI#1,CRI#3)为基本波束,t2和t3时刻发起的向TRP2上报的Report#2和Report#3为非基本波束上报,其报告内容中的CRI需要始终与基本波束上报中的CRI(即(CRI#1,CRI#3))两两组合后,至少存在一个CRI组合能被终端同时接收。

另外,上报时的所有的波束对应关系可参示例2中的描述,而本示例3中以完全配对方式为对应条件进行的波束选择和上报。当存在多个能与基本 波束上报中的CRI被同时接收的波束对存在时,终端会根据一定规则再次进行选择,择出两个CRI并进行上报,比如选择L1-RSRP最高的。
在t4时刻,向TRP1上报的Report#4发起,由于Report#4为基本波束上报,因此其波束选择不受限制,而t5时刻发起的Report#5需要根据Report#4的波束报告内容进行波束选择。
示例4
本示例4中的CSI-RS资源、资源分组和报告配置方法如方法200中的示例(模式二)所述,为避免重复,在此不再赘述。
与示例2相同,本示例4主要是针对TRP间是非理想回传线路的情况。在TRP间不能及时共享波束信息的情况下,通常采用向两个TRP分别进行波束上报。本示例4可提高向两个TRP分别上报的波束满足同时接收的概率,从而增强非理想回传线路下多TRP的同时传输能力。

在multi-DCI的场景下,网络侧设备与终端提前约定,定义与CORESETPoolindex=0关联的TRP为基本TRP,向基本TRP进行的波束上报为基本波束上报,即在本实例中TRP1为基本TRP,向TRP1上报的波束报告为基本波束报告。如图7b所示,在t1时刻,Report#1上报的(CRI#1,CRI#3)为基本波束对,t2和t3时刻发起向TRP2上报的Report#2和Report#3为非基 本波束上报,其报告内容中的CRI需要始终与基本波束上报中的CRI,即(CRI#1,CRI#3)能同时接收。当存在多个能与基本波束上报中的CRI能同时接收的波束对存在,则终端会根据测量结果,例如L1-RSRP再次进行选择,择出一对进行上报,如表4中的第2行所示。在t4时刻,向TRP1上报的Report#4发起,由于Report#4为基本波束上报,因此其波束选择不受限制,而t5时刻发起的Report#5需要根据Report#4的波束报告内容进行波束选择。
示例5
本示例5中的CSI-RS资源、资源分组和报告配置方法如方法200中的示例(模式二)所述,为避免重复,在此不再赘述。
与示例2相同,本示例5是针对TRP间是非理想回传线路的情况。在TRP间不能及时共享波束信息的情况下,通常采用向两个TRP分别进行波束上报。本示例5可提高向两个TRP分别上报的波束满足同时接收的概率,从而增强非理想回传线路下多TRP的同时传输能力。

在multi-DCI TRP的场景下,如表5中所示,在TRP1进行CSI上报波束对(CRI#1,CRI#3),且TRP1根据资源分组,可确定属于自身的波束为CRI#1的情况下,与之相关联的CSI报告2至少需要满足以下一个条件:
(1)CSI报告2中关联到TRP1的部分与CSI报告1中相同,如表5中的第三行所示。由于CSI报告2中的波束对是能同时被UE接收的,且其包含CRI#1,因此CSI报告2中关联到TRP2的部分能与CSI报告1中关联到TRP1的部分实现同时传输。
(2)CSI报告2中关联到TRP1的部分与CSI报告1中不同,CSI报告2中关联到TRP2的部分与CSI报告1中关联到TRP1中的部分能够同时接收,如表5中的第四行所示。终端根据测量结果从两对满足同时接收的波束对中选择了(CRI#2,CRI#4)进行上报,由于CSI报告2中不包含CRI#1,为了保证同时传输,需要CSI报告2中关联到TRP2的部分与CRI#1能够同时接收,而(CRI#1,CRI#4)能被终端同时接收。
本实施例给出的方法400中,通过提供不同的波束选择与上报方式,有效提高了向多个TRP分别上报的波束满足同时接收的概率,从而增强非理想回传线路下多TRP的同时传输能力。
如图8所示,为本申请一示例性实施例提供的信道状态信息的报告方法800的流程示意图,该方法800可以应用但不限于终端,具体可由安装于终端中的硬件和/或软件执行。所述方法800至少包括以下步骤。
S810,从各目标资源组中选取一个或多个目标资源。
其中,关于S810的实现过程可参照前述方法实施例200-400中的相关描述,为避免重复,在此不再赘述。
S820,开启预配置的报告延迟窗。
其中,可在任意CSI报告发起时便开启所述报告延迟窗。本实施例中,位于同一所述报告延迟窗(delay window)内的多个CSI报告相同,或者, 位于同一所述报告延迟窗内的多个CSI报告中的CRI和/或SSB RI相同。例如,在窗口内所有CSI报告的内容均相同或基于不同传输时刻下相同的n(n<=N)组CSI或SS/PBCH资源而获得的波束组或CSI(即CRI/SSBRI相同,但PMI、CQI等CSI参数可不同)。
一种实现方式中,所述报告延迟窗可为绝对时间窗口(如周期性/半持续性CSI报告))或相对时间窗口(如非周期CSI报告)。另外,所述报告延迟窗可通过以下(1)-(5)中的任一方式确定。
(1)所述终端与网络侧设备协商确定。
(2)隐式获取。
(3)RRC指示。
(4)MAC CE指示。
(5)DCI指示。
可以理解为,所述报告延迟窗可以通过RRC、DCI、MAC CE单独指示,也可以与触发上报的信令同时指示,例如,在所述报告延迟窗通过所述DCI指示的情况下,所述报告延迟窗通过所述DCI中的CSI终端请求域指示。
示例性的,假设CSI报告相同、且采用前述模式二中所述的CSI报告配置方式,那么,请结合参阅图9a和图9b所示,由于周期性CSI上报的时域资源是RRC配置,是提前可知的且能保持较长时间,因此基于一个关联两个CSI上报的周期性CSI resport setting和两个周期性的CSI report setting的报告延迟窗口是绝对窗口。其中,一个关联两个CSI上报的周期性CSI resport setting的延迟窗口的长度设置为两次CSI上报间的时间间隔,即timeoffset,两个周期性的CSI report setting的延迟窗口长度为两个CSI report setting间的时间间隔。
S830,根据各所述目标资源,确定第一信道状态信息CSI报告。
其中,S830的实现过程除可参照前述各方法实施例中的相关描述之外,一种实现方式中,S830中所述的根据各所述目标资源,确定第一CSI报告的 实现过程至少可以包括:根据各所述目标资源以及第二CSI报告,确定所述第一CSI报告;其中,所述第二CSI报告的确定过程可参照前述第一CSI报告的描述,在此不再赘述,所述第二CSI报告的反馈时间早于所述第一CSI报告、且所述第二CSI报告的反馈时间以及所述第一CSI报告的反馈时间均位于所述报告延迟窗内。
示例性的,假设第二CSI报告中的CRI#1、CRI#2能被同时接收,那么基于目标资源确定的第一CSI报告中包括的CRI#x、CRI#y,与第二CSI报告中的CRI#1、CRI#2的组合,至少部分能被同时接收。
示例性的,再次参阅图9a和9b,由于在CSI上报之前所有CSI-RS都已接收并测量,在这种情况下,处于同一个报告延迟窗口内的CSI报告内容相同,如图9a和9b中的Report#1和Report#2,但超出报告延迟窗口后的CSI报告则不再需要满足CSI报告内容相同的条件,如图9a和9b中的Report#2和Report#3。
由于groupBasedBeamReporting=enabled,因此终端会上报一对能被同时接收的波束,而两次CSI报告内容相同,则TRP1和TRP2可根据接收到的波束进行同时传输。需要注意的是,该有效波束对会一直工作,直至下一个处于同一报告延迟窗口的两次报告出现的时刻或者TRP之间的回传信息到达的时刻。
由于半持续CSI上报是基于MAC CE激活的周期性CSI上报,因此其时域特性仍可提前协调得知,因此其对应的报告延迟窗口是绝对窗口。
此外,如图9c所示,为一个关联两个CSI上报的非周期CSI report setting的延迟窗口示意图。由于非周期CSI报告是由DCI触发的,网络侧设备无法固定非周期CSI报告的触发时间,因此非周期CSI报告的报告延迟窗口是相对窗口,其起始点为非周期CSI报告触发时刻,长度由网络配置或由终端能力决定。与图9a和9b相同,由于在CSI上报之前所有CSI-RS都已接收并测量,因此在这种情况下处于同一个延迟窗口内的CSI报告内容相同。
假设网络侧设备共配置2个CSI-RS资源(即目标资源),将2个CSI-RS资源分为两组,每组分别各有一个CSI-RS资源。那么,参阅图9d:
在t3时刻,Report#1发起,终端根据测量后的结果向TRP1进行上报,CSI报告内容中的CSI-RS资源指示为(CRI#1,CRI#2)。
在t4时刻,终端接收到CSI-RS#1。
在t5时刻,Report#2发起,终端根据测量后的结果向TRP1进行上报,由于仅有两个CSI-RS资源,因此CSI报告内容中的CSI-RS资源指示仍为(CRI#1,CRI#2)。
虽然两次CSI报告都存在一个报告延迟窗口中且反馈的CRI相同,但在当前情况下,由于CSI-RS#1是重新发送的,使得两次CSI报告中的CQI、RI以及PMI等其余CSI报告内容可能不同。因此,若报告延迟窗口中存在多个基于不同时刻的相同CSI-RS资源的CSI报告,仅需要保证CSI报告内容中的CRI/SSBRI相同。CRI/SSBRI相同则表明两次报告所选择的波束相同,由于在group-based beam report中,每个CSI报告的波束对都是能被UE同时接收的,因此TRP1和TRP2根据接收到的波束可实现同时传输。
S840,反馈所述第一CSI报告。
其中,S840的实现过程可参照前述S230、S430中的描述,为避免重复,在此不再赘述。
本实施例给出的方法800中,在目标资源组的基础上,进一步基于报告延迟窗进行波束的选择和上报,由此,能够进一步增强了多TRP间多TRP/panel的同时传输能力。
如图10所示,为本申请一示例性实施例提供的信道状态信息的报告方法1000的流程示意图,该方法1000可以应用但不限于终端,具体可由安装于终端中的硬件和/或软件执行。所述方法1000至少包括以下步骤。
S1010,从各目标资源组中选取一个或多个目标资源。
S1020,根据各所述目标资源,确定第一信道状态信息CSI报告。
其中,S1010和S1020中的实现过程可参照各方法实施例中的相关描述,为避免重复,在此不再赘述。
S1030,反馈所述第一CSI报告。
其中,S1030的实现过程除可参照各方法实施例中的相关描述之外,一种实现方式中,所述反馈第一CSI报告包括:在所述终端上报联合处理多个CSI报告所需时间、且所述第一CSI报告与其他CSI报告关联的情况下,按照多个CSI报告联合处理所需时间处理所述第一CSI报告,所述其他CSI报告为除所述第一CSI报告之外的CSI报告。
另一种实现方式中,在按照预定义的CSI处理时间处理第一CSI报告、且预定义的CSI处理窗口中仅存在一个第一CSI报告的情况下,反馈所述第一CSI报告。
其中,前述的CSI处理时间包括与其他CSI报告无关联情况下的CSI处理时间,所述其他CSI报告为除所述第一CSI报告之外的CSI报告。所述CSI处理时间窗口为CSI报告发起到上报所需要的计算处理时间。
示例性的,下面结合图11a至图11c对前述的CSI处理时间以及CSI处理窗口进行介绍。
请结合参阅图11a,一个CSI报告处理窗口的起始位置为CSI报告的发起时刻,即t1时刻,终点位置为与之相关联的最后一个RS计算结束的时刻,即t2时刻。其中,Δt表示处理时延。两个CSI报告联合处理时间窗口的起始位置为第一个CSI报告发起的时刻,即t1时刻,终点位置为与两个CSI报告相关联所有RS中的最后一个RS计算结束的时刻,即t4时刻。不同CSI报告所需要的处理时间长度不同,为了保证窗口的通用性,可将窗口长度设置为略大于统计得到的窗口长度最大值的一个固定值,如图11a中的一个CSI报告处理窗口长度可设置为一个略大于t2-t1的固定值。
当任意CSI报告发起时,CSI处理时间窗口便开启。当两次CSI报告的 时间间隔小于一个CSI报告处理窗口的长度时,即在一个CSI处理时间窗口中存在两次CSI报告时,如图11b中的Report#2和Report#3所示。在这种情况下,若Report#2和Report#3所关联的CSI-RS资源或SS/PBCH块资源不同,终端则会按照一定规则仅选择一个CSI报告进行上报,比如根据CSI报告的发起时间,选择发起时间早的进行上报;或者根据CSI报告所关联的CSI-RS资源或SS/PBCH块资源的测量情况,选择一个测量结果较好的CSI报告进行上报。
对于CSI处理时间窗口的时间线定义为多个CSI报告联合处理的情况,由于在CSI处理窗口内多个CSI报告所需要的测量并统计的结果都已得到,因此可允许多个CSI报告在一个CSI处理时间窗口内进行上报,如图11c所示。
如图12所示,为本申请一示例性实施例提供的信道状态信息的报告方法1200的流程示意图,该方法1200可以应用但不限于网络侧设备,具体可由安装于网络侧设备中的硬件和/或软件执行。所述方法1200至少包括以下步骤。
S1210,发送资源指示信息给终端,所述资源指示信息用于向终端指示多个目标资源组,使得所述终端基于所述多个目标资源组上报第一CSI报告,各所述目标资源组分别对应不同的目标TRP。
其中,关于S1210的实现过程可参照前述方法200、400、700、1000中的相关描述,为避免重复,在此不再赘述。
本实施例给出的方法1200中,通过资源配置的方式,使得终端向目标TRP上报的CSI报告中的目标资源对应于目标TRP的CSI-RS资源等,从而有效的增强了多TRP间多TRP/panel的同时传输能力,如终端的同时接收能力、多TRP的同时发送能力等。
作为一种可能的实现方式,所述目标资源包括信道状态信息-参考信号 CSI-RS资源和/或SSB资源。
作为另一种可能的实现方式,每个所述目标资源组中包括预设数量个目标资源,所述预设数量为N/M的向上取整,或者,所述预设数量为N/M的向下取整,N≥M,所述N为所述网络侧设备配置的目标资源的总数量,M为所述资源指示信息指示的目标资源组的总数量。
作为又一种可能的实现方式,所述资源指示信息通过无线资源控制RRC、媒体访问控制控制单元MAC CE或下行控制信息DCI传输。
作为又一种可能的实现方式,所述方法还包括:在上报的多个CSI报告中存在CSI报告冲突、且预配置的CSI处理时间为所述终端处理一个CSI报告所需时间的情况下,根据CSI处理能力配置所述CSI报告时间间隔,其中,所述CSI处理能力是由所述终端上报的,所述CSI报告时间间隔不小于所述CSI处理能力对应的时间。
作为又一种可能的实现方式,所述方法还包括:在上报的多个CSI报告中存在CSI报告冲突、且预配置的CSI处理时间为所述终端处理多个CSI报告所需时间的情况下,按照所述终端处理多个所述CSI报告关联的所有RS中的最后一个RS所需要的时间,计算目标CSI处理时间;根据目标CSI处理时间配置CSI报告时间间隔。
需要说明的是,本申请实施例提供的前述各方法实施例中,执行主体可以为信道状态信息的报告装置,或者,该信道状态信息的报告装置中的用于执行信道状态信息的报告方法的控制模块。后续部分中,本申请实施例中以信道状态信息的报告装置执行信道状态信息的报告方法为例,说明本申请实施例提供的信道状态信息的报告装置。
