下面结合附图介绍本申请的实施例。本申请实施例提供的模式指示方法、终端设备及网络设备可以应用于无线通信系统中。该无线通信系统可以为采用第五代(5th Generation,5G)移动通信技术的系统(以下均简称为5G系统),所述领域技术人员可以了解,5G NR系统仅为示例,不为限制。
参见图1,图1是本申请实施例可应用的一种网络系统的结构图,如图1所示,包括用户终端11和基站12,其中,用户终端11可以是用户设备(User Equipment,UE),例如:可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant,简称PDA)、移动上网装置(Mobile Internet Device,MID)或可穿戴式设备(Wearable Device)等终端侧设备,需要说明的是,在本申请实施例中并不限定用户终端11的具体类型。上述基站12可以是5G及以后版本的基站(例如:gNB、5G NR NB),或者其他通信系统中的基站,或者称之为节点B,需要说明的是,在本申请实施例中仅以5G基站为例,但是并不限定基站12 的具体类型。
首先对与本公开实施例相关的一些概念进行说明如下。
1、信道状态信息(Channel State Information,CSI)
CSI的反馈决定了多输入多输出(User Multiple-Input Multiple-Output,MIMO)传输的性能,因此在整个MIMO设计中具有举足轻重的作用。长期演进(Long Term Evolution,LTE)系统中在不同的标准化版本(Rel-8~Rel-14)中定义了多种不同的反馈类型以支持不同MIMO传输方案的CSI信道信息反馈。这种设计导致了不同传输方案以及信息反馈的分散和复杂化。在第五代(5Generation,5G)通信系统中为了避免引入多种反馈类型/子反馈类型,考虑设计统一的CSI反馈框架。系统设计通过将CSI测量和CSI反馈方式进行解耦,将测量资源和测量操作与具体上报操作分离,以更加灵活方式支持不同的MIMO传输方式在多种场景和多种频带应用。另外,对于5G系统新出现的波束管理需求,还需要上报波束指示及相应的参考信号测量功率(Reference Signal Received Power,RSRP)等信息。
在新空口(New Radio,NR)系统中,CSI可以包括信道质量指示(Channel Quality Indicator,CQI)、预编码矩阵指示(Precoding Matrix Indicator,PMI)、信道状态信息参考信号(Channel State Information-Reference Signal,CSI-RS)资源指示(CRI)、同步信号(Synchronization Signal,SS)/物理广播信道(Physical Broadcast Channel,PBCH)块资源指示(SSBRI)、层指示(LI)、秩指示(Rank Indication,RI)以及L1-RSRP。其中,SSBRI、LI和L1-RSRP是在LTE系统的CSI反馈基础上新增的反馈量。LI用于指示PMI中最强的列,用于相位跟踪参考信号(Phase tracking reference signal,PT-RS)映射。SSBRI和L1-RSRP用于波束管理,一个指示波束索引,另一个指示波束强度。
根据上述将CSI测量和CSI反馈解耦的原则,系统将为每个用户设备(User Equipment,UE,也称终端或终端设备)配置N≥1个用于上报不同测量结果的上报反馈设置(Reporting Setting),以及M≥1个CSI-RS测量资源设置(Resource Setting)。每个Reporting Setting关联至1个或多个Resource Retting,用于信道和干扰测量与上报,这样可以根据不同终端需求和应用场景,灵活设置不同测量集合与上报组合。如图2所示,对于某个终端,设置了三个测 量集合,分别对应于不同CSI-RS的测量资源组合;同时,该终端还配置了两种上报设置,对于设置0上报三个测量集合的结果,而设置1则上报一个测量集合的结果。
以上过程是针对单传输点(Transmission Reference Point,TRP)是传输设计的,不能反映M-TRP传输时的信道质量。针对这一问题,第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)在Rel-17中设立了关于M-TRP CSI反馈增强的议题。根据目前的标准化讨论结论,在M-TRP的CSI测量过程中,使用一个资源集(resource set)中的若干资源(resource)作为参与协作的各TRP的信道测量资源(Channel Measurement Resources,CMR)。终端基于对上述resource的测量,按照不同的传输方案假设计算并上报相应的CSI。
在上述过程中,尚未明确的问题包括:
a、CSI上报配置过程中如何将resource和TRP对应。例如终端至少应当知道,哪些resource与另外哪一些resource不属于同一个TRP;
b、终端在CSI计算和上报中,如何体现出CSI与终端选择的TRP以及传输方案之间的对应关系;或者说,终端如何上报其推荐的TRP以及推荐的传输方案。
2、准共址(Quasi Co-Location,QCL)
传输配置指示(Transport Configuration Indication,TCI)状态(state)指示及QCL:CSI RS的TCI state包含最多两种QCL类型,每种QCL类型对应于一个参考信号。
本公开实施例提供了信息上报、接收方法、终端设备及网络设备,用以解决相关技术中的针对多点协作传输的CSI计算与上报的过程中,无法体现CSI与终端选择的TRP的对应关系,无法保证网络传输可靠性的问题。
其中,方法和装置是基于同一申请构思的,由于方法和装置解决问题的原理相似,因此装置和方法的实施可以相互参见,重复之处不再赘述。

S21、空分复用(SDM);
此种情况指的是,当没有用DCI指示终端设备时,该DCI字段“时域资源分配”指示包含PDSCH-TimeDomainResourceAllocation-r16中的repetitionNumber-r16的字段,并且用DCI字段“传输配置指示”和DCI中两个CDM组内的DMRS端口的码点中的两个TCI状态指示字段“天线端口”。
S22、频分复用(FDM)方式A;
此种情况指的是,对于由设置为“FDM方式A”的更高层参数RepetitionScheme-r16配置的终端设备,并且当在DCI字段“传输配置指示”和DCI字段“天线端口”中的一个CDM组内的DMRS端口的码点中用两个TCI状态指示终端设备。

进一步需要说明的是,本公开的至少一个实施例中,步骤S301的具体实现方式为:
接收网络设备发送的分组配置信息,根据所述分组配置信息,确定用于信道测量的资源配置信息。
需要说明的是,该分组配置信息指的是网络设备告知终端设备如何进行分组的配置,以便终端设备明确网络设备侧是如何进行资源分组的,本公开的至少一个实施例中,将用于信道测量的资源集分成至少两组。
进一步需要说明的是,所述分组配置信息,包括以下任一项:
A11、用于信道测量的资源集中的每个资源所对应的组标识信息;
需要说明的是,当网络设备告知终端每个资源所对应的组标识信息后,终端设备便可根据该组标识信息,确定每个资源具体属于哪个组,此种情况下,终端获取到几个组标识信息,则用于信道测量的资源集便被分成几组,同时终端也能确定每组中有多少个资源。
A12、每个资源组的大小;
需要说明的是,此种情况是,网络设备告知终端设备每个资源组的大小,终端依据该资源组的大小,进行资源组中所包含的资源的确定。若网络设备配置了M个资源组,每个资源组中的资源个数分别为N 1,…,N M,则终端设备确定编号1至N 1的一组资源为第一组;编号N 1+1至N 1+N 2的一组资源为第二组;依次类推,编号N 1+N 2+…+N M-1+1至N 1+N 2+…+N M的一组资源为第N M组。
例如,网络设备将用于信道测量的资源组中的资源分成2组,则终端设备最终确定,编号1至N 1的一组资源为第一组,编号N 1+1至N 1+N 2的一组资源为第二组。
A13、用于信道测量的资源集中的资源对应的比特位图(bitmap);
需要说明的是,此种方式是网络设备直接以bitmap方式,告知终端设备 每个资源的分组编号,终端设备依据该分组编号确定用于信道测量的资源集被分成几组,同时终端也能确定每组中有多少资源。
假设用于信道测量的资源集中的资源编号为1至R,用长度为R的bitmap指示每个资源所属的分组,则该bitmap的第r(r=1,…,R)个元素的取值即为第r个资源所属的资源分组标识。
例如,,网络设备将用于信道测量的资源组中的资源分成2组,则bitmap的第1个元素的取值即为第1个资源的资源分组标识(例如,该资源分组标识为1或者2),bitmap的第2个元素的取值即为第2个资源的资源分组标识(例如,该资源分组标识为1或者2),依此类推。
A14、用于信道测量的资源集中的资源的准共址QCL关系;
需要说明的是,此种情况下,所述根据所述分组配置信息,确定用于信道测量的资源配置信息,包括:
对于信道测量的资源集中的第一资源和第二资源,若所述第一资源和所述第二资源与第一参考信号具有第一类型的QCL关系,则确定第一资源和第二资源属于同一个资源组;
其中,所述第一类型包括以下一项:
类型A;
类型B;
类型C;
类型D;
类型A和类型D;
类型C和类型D。
也就是说,此种情况指的是,对于用于信道测量的资源集中的任意两个资源,如果其与同一个参考信号具有第一类型的QCL关系(或者说在这两个资源的TCI状态中第一类型所对应的参考信号相同)则这两个资源处于相同的分组。
进一步还需要说明的是,所述分组配置信息中还包括:指示至少两个资源组中的第一资源组中的资源用进行单点传输的传输方式获取CSI的标识信息。
也就是说,分组配置信息还可以用于指示若干个资源组中所包含的资源只能用进行单点传输的传输方式获取CSI。
进一步需要说明的是,所述上报配置的配置方式包括以下至少一项:
B11、网络设备配置;
B12、预定义;
B13、终端上报配置;
需要说明的是,此种情况指的是,终端设备推荐上报时可使用的上报配置集合,由网络设备从终端推荐的上报配置集合中选择上报配置并通知给终端设备。
B14、根据资源配置信息确定;
需要说明的是,此种情况指的是:如果根据网络设备的配置,该资源集中的所有资源只能用单点传输的传输方式进行CSI的获取,则终端只能上报若干个基于单点传输的传输方式所获取的CSI。
进一步地,所述上报配置包括以下至少一项:
C11、上报至少一个基于单点传输的传输方式所获取的CSI;
C12、上报至少一个基于多点传输的传输方式所获取的CSI。
进一步需要说明的是,在所述上报配置包括:上报至少一个基于多点传输的传输方式所获取的CSI的情况下,所述根据所述资源配置信息和所述上报配置,获取至少一个CSI,包括:
从所述至少两个资源组中选择至少两组,并从所述至少两组中的每组中分别选择一个资源进行信道测量,获取对应的CSI。
也就是说,此种情况下,终端设备需要从M(M大于或等于2)个资源组中选出至少两组,并从中分别选择出一个资源进行信道测量;然后终端假设数据按照某种类型的多点传输方式通过上述多个资源对应的信道传输;终端设备基于以上假设计算相应的CSI。
进一步需要说明的是,在所述上报配置包括:上报至少一个基于单点传输的传输方式所获取的CSI的情况下,所述根据所述资源配置信息和所述上报配置,获取至少一个CSI,包括:
从第一资源中选择一个第二资源进行信道测量,获取对应的CSI;
其中,所述第一资源为所有能够用于基于单点传输的传输方式所获取的CSI的资源,或者所述第一资源为网络设备配置的所有资源。
需要说明的是,该能够用于基于单点传输的传输方式所获取的CSI的资源是由网络设备配置的,在网络设备没有额外配置的情况下,该第一资源便为网络设备配置的所有资源。
也就是说,此种情况下,终端设备需要从第一资源中选出一个资源,并用该资源进行信道测量;然后终端设备假设数据按照某种类型的单点传输方式通过上述资源对应的信道传输;终端设备基于以上假设计算相应的CSI。
需要说明的是,网络设备配置的所有资源组中,可以只有基于单点传输的传输方式的资源,也可以只有基于多点传输的传输方式的资源,或者,还可以由同时有基于单点传输的传输方式的资源和基于多点传输的传输方式的资源,针对不同传输方式的资源,终端设备可以采用的上报配置不同,而对应的目标CSI中的第一信息的个数也不同,下面对不同的情况分别说明如下。

Figure PCTCN2021141162-appb-000026
例如,第一个资源组中有4个资源,第二个资源组也有4个,通过CSI的上报配置确定的从两个资源组中各取一个资源构成的组合中,能用于多点传输假设的组合有8个,则可以用3比特CRI进行指示。
