高频拥有丰富的频谱资源，可以提高无线通信系统的传输效率。但是由于高频的载频高、路径损耗大，需要采用波束赋形将发送能量集中于接收端方向 以获得增益。一般来说，发送端包括Nt个发送波束，接收端包括Nr个接收波束，最多经过Nt*Nr次波束扫描就能选出最优波束。另外也可以采用分阶段波束扫描的方法：固定接收波束扫描发送波束或固定发送波束扫描接收波束，该方法可能需要Nt+Nr次波束扫描来选出次优波束。但是当Nt和Nr的取值较大时，上述两种波束扫描方法对资源的开销还是很大的。为此，可以采用AI的方式，利用历史发送波束来预测未来发送波束，和/或，利用历史接收波束来预测未来接收波束，或者，用历史发送接收波束对，预测未来发送接收波束对，比如用N个历史时刻的波束组(本申请中波束包括发送波束、接收波束、发送接收波束对)预测未来M个时刻的波束组，那么就可以减小M个未来时隙的参考信号发送，从而可以节省参考信号的资源开销。例如，利用N个参考时隙之前的第一波束参数信息组获取M个参考时隙之后的第二波束参数信息组。然而，在有些场景中，通信节点并不能有效地获得N个第一波束参数信息组，只能获得K个第一波束参数信息组，K小于N。因此，如何获取这种场景下的第二波束参数信息组，是一个亟需解决的问题。
本申请提供的波束参数信息的反馈、接收方法可以应用于多类无线通信系统中，例如长期演进(long term evolution，LTE)系统、第四代移动通信技术(4th-generation，4G)系统、第五代移动通信技术(5th-generation，5G)系统、LTE与5G混合架构系统、5G新无线电(New Radio，NR)系统、以及未来通信发展中出现的新的通信系统，如第六代移动通信技术(6th-generation，6G)系统等。图1示出了一实施例提供的一种无线通信系统的组网示意图。如图1所示，该无线通信系统包括终端设备110、接入网设备120和核心网设备130。

在一实施例中，传输包括发送或接收。比如发送数据或者信号，接收数据或者信号。
在一实施例中，为了计算信道状态信息或者进行信道估计，移动性管理，定位等，需要基站或者用户发送参考信号(Reference Signal，RS)，参考信号包括但不限于信道状态信息参考信号(Channel-State Information reference signal，CSI-RS)，它包括零功率的CSI-RS(Zero Power CSI-RS，ZP CSI-RS)和非零功率的CSI-RS(Non-Zero Power CSI-RS，NZP CSI-RS)，信道状态信息干扰测量信号(Channel-State Information-Interference Measurement，C SI-IM)，探测参考 信号(Sounding Reference Signal，SRS)，同步信号块(Synchronization Signals Block，SSB)、物理广播信道(Physical Broadcast Channel，PBCH)、同步信号块/物理广播信道(SSB/PBCH)，NZP CSI-RS可以用来测量信道或者干扰，CSI-RS也可以用来做跟踪，叫做跟踪参考信号(CSI-RS for Tracking，TRS)，而CSI-IM一般用来测量干扰，SRS用来测量上行信道。另外，用于传输参考信号的时频资源包括的资源元素(Resource Element，RE)集合称为参考信号资源，比如，CSI-RS resource，SRS resource，CSI-IM resource，SSB resource。在本申请中，SSB包括同步信号块和/或物理广播信道。
在一实施例中，在通信系统中，传输参考信号的资源可以称为参考信号资源，为了节省信令开销等，可能会把多个参考信号资源组合成一个集合(比如CSI-RS resource set，CSI-IM resource set，SRS resource set)，一个参考信号资源集合包括至少一个参考信号资源，而多个参考信号资源集合可以都来自同一个参考信号资源设置(比如CSI-RS resource setting，SRS resource setting，其中CSI-RS resource setting可能和CSI-IM resource setting合并，都称为CSI-RS resource setting)来配置参考信号参数信息。
在一实施例中，基站配置参考信号配置信息，所述参考信号配置信息用于指示参信号资源的时频位置，时域特性(比如周期的参考信号、非周期的参考信号，半持续的参考信号)，参考信号资源的集合，准共位置信息，参考信号资源索引，参考信号资源集合索引等。一套参考信号配置信息对应一套参考信号资源。参考信号资源用于获取信道状态信息，比如波束参数信息组，其中一个波束参数信息组中包括至少一个波束参数信息。其中，一套参考信号资源(或者称为测量资源信息)包括CN个信道测量资源(Channel Measurement Resource，CMR)信息和/或CM个干扰测量资源(Interference Measurement Resource，IMR)信息，CN和CM为正整数。基站在一个报告配置(report config)或报告设置(reporting setting)中配置测量资源信息。在一些示例中，一个信道测量资源信息包括至少一个信道参考信号资源设置，比如至少一个CSI-RS resource setting或至少一个SRS resource setting，一个干扰测量资源信息包括至少一个干扰参考信号资源设置，比如至少一个CSI-IM resource setting。在一些示例中，一个信道测量资源信息包括至少一个信道参考信号资源集合，比如至少一个CSI-RS resource set或至少一个SRS resource set，一个干扰测量资源信息包括至少一个干扰参考信号资源集合，比如至少一个CSI-IM resource set。在一些示例中，一个信道测量资源信息包括至少一个信道参考信号资源，比如至少一个CSI-RS resource或至少一个SRS resource，一个干扰测量资源信息包括至少一个干扰参考信号资源，比如至少一个CSI-IM resource。
在一实施例中，波束包括发送波束、接收波束、预编码、预编码矩阵、预 编码矩阵索引，接收波束和发送波束对，发送波束和接收波束对。波束可以为一种资源(例如发端预编码，收端预编码、天线端口，天线权重矢量，天线权重矩阵等)，波束索引可以被替换为资源索引，因为波束可以与一些时频资源进行传输上的绑定。波束也可以为一种传输(发送/接收)方式；传输方式可以包括空分复用、频域/时域分集等。接收波束指示是指，发送端可以通过当前参考信号资源(或参考信号资源索引)和天线端口，与UE反馈报告的参考信号资源(或基准参考信号资源，参考信号资源索引)和天线端口的准共址(Quasi-Co-Location Indicator，QCL)假设来进行指示。波束对包括一个发送波束和一个接收波束的组合。
在一实施例中，波束方向或者波束角度可以包括以下至少之一：到达角(Angle Of Arrival，AOA)、离开角(Angle Of Departure，AOD)、ZOD(Zenith angle Of Departure)、ZOA(Zenith angle Of Arrival)、由AOA，AOD，ZOD，ZOA至少一个角度构造的向量或者向量索引，离散傅里叶变化(Discrete Fourier Transformation，DFT)矢量、码本中的码字、发送波束索引、接收波束索引、发送波束组索引、接收波束组索引。在一实施例中，波束指一个空域滤波器或者一个空间接收/发送参数，空域滤波可以是以下至少之一：DFT矢量，预编码矢量，DFT矩阵，预编码矩阵，或者多个DFT线性组合构成的矢量，多个预编码矢量线性组合构成的矢量。
在一实施例中，特别是在高频传输时，由于载频比较高，路径损失大，需要用到波束赋形，将能量集中在朝终端的方向传播，从而需要用到波束管理。其中波束管理包括但不限于波束扫描、波束跟踪和波束恢复几个方面，需要解决的核心问题是如何通过尽可能低的控制开销获取准确的波束对。其中，波束扫描包括发送端波束扫描和/或接收端波束扫描。为了减小波束扫描的开销，可以通过两阶段的扫描。在一实施例中，波束训练可以包括第一阶段，第二阶段，第三阶段的训练。其中，在第一阶段中同时扫描发送端的波束和接收端的波束；而在第二阶段的波束扫描中会固定一个接收波束，并扫描不同的发送波束；第三阶段为固定一个发送波束，扫描不同的接收波束。在一个示例中，比如通过发送NT个波束，固定接收，重复参数repetition取值为off，然后测量其中的NT个波束对应的参考信号接收功率(Reference Signal Received Power，RSRP)，找到优选的L个进行上报。在一个示例中，通过发送1个波束，NR个接收波束接收，重复参数取值为on，然后测量其中的NR个波束对应的RSRP，找到最优的L个进行上报。在NR和NT都很大的时候，开销是非常大的，所以需要非常大的参考信号开销。这里，NR，NT为正整数。可以用AI的波束预测功能来减小波束扫描时的参考信号开销。其中，AI的波束预测包括空域波束预测和时域波束预测，或者空时波束预测。
在一些示例中，可以用到AI来实现空域波束预测，即只输入一个波束参数信息组，其中波束参数信息组包括L0个波束参数信息，根据L0波束参数信息预测另外一个波束信息组，这个波束信息组包括L1个波束参数信息，这里，L1个波束参数信息可以包括L0个波束参数信息，其中，L，L1，L0均为正整数，L0＜L1，且它们都是正整数，波束可以为发送波束、接收波束或发送接收波束对。每个波束可以对应一个波束方向。在一些示例中，空域波束预测可以通过AI模块实现，比如通过一个神经网络实现。L0个波束对应的波束参数信息组合成一个波束参数信息数组(第一波束参数信息数组)输入神经网络，神经网络输出L1个波束对应的波束参数信息数组(第二波束参数信息数组)，并将第二波束参数信息数组中的K个最大值对应的索引确定K个优选的波束。在一些示例中，也可以通过非AI的方式来实现空域波束预测，比如线性映射或者非线性映射等方式来实现空域波束预测。
在一些示例中，可以用到AI来实现时域波束预测，即只输入N个波束参数信息组，其中每个波束参数信息组包括L0个波束参数信息，根据N个第一波束参数信息组预测M个第二波束参数信息组。其中，M个第二波束参数信息组的每个波束参数信息组包括L1个波束参数信息。其中，N、M，L，L1，L0均为正整数，L0≤L1，且它们都是正整数，波束可以为发送波束、接收波束或发送接收波束对。每个波束可以对应一个波束方向。这里，N个第一波束参数信息组为参考时隙之前的波束参数信息，而M个第二波束参数信息组为参考时隙之后的波束参数信息。这里，当L0＝L1时为时域波束预测，当L0＜L1时为空时波束预测。在一些示例中，时域波束预测可以通过AI模块实现，比如通过一个神经网络实现。输入N个波束参数信息组，其中每个波束参数信息组包括L0个波束参数信息，将N*L0个波束参数信息合成一个更大的波束参数信息数组(第一波束参数信息数组)输入神经网络，神经网络输出M个波束参数信息组，其中每个波束参数信息组包括L1个波束参数信息，也可以将M*L1个波束参数信息组合成一个波束参数信息数组(第二波束参数信息数组)，对于M组波束里的每组波束，将其中K个最大波束参数信息对应的索引确定为该波束信息组的K个优选的波束。其中，L1一般来说大于等L0，且都为正整数。在一些示例中，也可以通过非AI的方式来实现时域波束预测，比如线性映射或者非线性映射等方式来实现时域波束预测。
在一些示例中，通过线上训练或者线下训练的方式获得神经网络的参数。比如通过输入至少一个样本和标签，训练神经网络模型获得神经网络参数。在一些示例中，样本为一个终端测量得到的一个第一波束参数信息数组，标签为一个终端测量得到的一个第一波束参数信息数组对应的第二波束参数信息数组。在训练网络时，第一波束参数信息数组和第二波束参数信息数组具有对应 关系，例如为一一对应关系。在进行神经网络部署或者测试阶段，通过将第一波束参数信息数组输入神经网络以输出一个预测的第二波束参数信息数组，比较预测的第二波束参数信息数组和标签对应的第二波束参数信息数组，就可以知道网络的预测性能，以及根据两者的损失函数来训练神经网络。
在一些示例中，将发送波束和/或接收波束索引按约定的方式编号，形成波束索引。其中，一个波束索引包括以下之一：发送波束索引，接收波束索引，发送接收波束对索引。一个波束索引对应着一个波束方向，或者波束方向对应的矢量或矩阵。终端接收参考信号(比如CSI-RS，SSB等)并测量每个波束对应的波束参数信息，组合多个波束对应的波束参数信息得到波束参数信息数组。一般来说，第一波束参数信息数组为第一波束集合对应的波束参数信息形成的波束参数信息数组，第二波束参数信息数组为第二波束集合对应的波束参数信息形成的波束参数信息数组。而第一波束集合为第二波束集合的一个子集合。
在一些示例中，需要对第一波束参数信息数组中的元素进归一化处理，以便于神经网络更快的收敛。所谓归一化是指将一个数组里的元素取值归一化到一个大于等于a，小于等于b的区间的一个值。在一个示例中，a＝-0.5，b＝0.5；在一个示例中，a＝0，b＝1；在一个示例中，将数组里的元素除以这个数组元素里的绝对值最大的数以实现归一化；在一个示例中，将数组里的元素除以这个数组元素里的方差以实现归一化；在一个示例中，将数组里的元素除以一个固定的值(比如所有样本里的所有元素的最大值)以实现归一化；在一个示例中，将数组里的元素除以一个统计的值(比如所有样本里的所有元素的统计的方差值)以实现归一化。对于索引值，比如波束索引，CRI，SSBRI等，可以通过独热编码(One-Hot Encoding)实现归一化。
在一些示例中，波束参数信息数组是一维的数组，比如是一个向量。在一些示例中，波束参数信息数组是二维的数组，比如是一个矩阵。在一些示例中，波束参数信息数组是大于二维的数组，比如是一个张量。其中，向量和矩阵也可以看成张量的一种特殊情况。
在一实施例中，波束参数信息为一个波束对应的层1的参考信号接收功率(L1 Reference Signal Received Power，L1-RSRP或RSRP)；在一实施例中，波束参数信息为一个波束对应的层1的参考信号信干噪比(L1Signal-to-Interference Noise Ratio，L1-SINR或SINR)；在一实施例中，波束参数信息为一个波束对应的参考信号接收质量(Reference Signal Received Quality，RSRQ)；在一实施例中，波束参数信息为一个波束对应的波束角度(AOA，ZOA，AOD，ZOD等至少之一，有时也分别称为水平到达角度，垂直到达角，水平离开角，垂直离开角)；在一实施例中，波束参数信息为一个波束对应的发送波 束索引；在一实施例中，波束参数信息为一个波束对应的接收波束索引；在一实施例中，波束参数信息为一个波束对应的发送波束和接收波束对索引(简称为波束对索引或波束对)；在一实施例中，波束参数信息为一个波束对应的波束域接收功率映射(Beam Domain Receive Power Map，BDRPM)；在一实施例中，波束参数信息为一个波束对应的信道状态信息参考信号资源指示(CSI-RS Resource Indicator，CRI)；在一实施例中，波束参数信息为一个波束对应的同步信号块资源指示(Synchronization Signals Block Resource Indicator，SSBRI)。在一实施例中，波束参数信息组为至少一个波束对应的以下波束参数信息的至少两个的组合：RSRP、RSRQ、SINR、波束角度、发送波束索引，接收波束索引，波束对索引、CRI，SSBRI等，在一个实施例中，一个波束参数信息组包括至少一个波束参数信息。在一实施例中，波束参数信息为RSRP、RSRQ、SINR之一的线性值。在一实施例中，波束参数信息为RSRP、RSRQ、SINR之一的对数值或者叫分贝值(DB)。
在一实施例中，波束参数信息可基于CSI-RS测量得到。在一实施例中，波束参数信息可基于SSB测量得到。在一实施例中，波束参数信息可基于SRS测量得到。
在一示例中，为了传输波束参数信息组，比如终端反馈波束参数信息，基站接收波束参数信息组。在一些示例中，波束参数信息组也是一种信道状态信息，需要在CSI报告定义的传输资源中传输。为了传输波束参数信息组，终端和基站定义一个CSI报告(CSI report或者CSI report congfig)，其中CSI报告至少定义了如下参数之一：用于反馈CSI的时频资源，CSI包括的报告质量reportQuantity，CSI反馈的时域类别reportConfigType，信道测量资源，干扰测量资源，测量的带宽大小等信息。其中CSI报告可以在上行传输资源上传输，其中上行传输资源包括物理上行共享信道(Physical Uplink Shared Channel，PUSCH)和PUCCH，而CSI report也包括时域特性，包括周期的CSI报告(periodic CSI report，P-CSI)，非周期的CSI报告(aperiodic CSI report，AP-CSI)，半持续的CSI报告(semi-persistent CSI report，SP-CSI)。一般来说，P-CSI传输的比特数目相对较小，在PUCCH上传输，而A-CSI传输的比特数较多，一般在PUSCH上传输，而SP-CSI可以基于PUSCH上传输，也可以基于PUCCH上传输。其中，基于PUCCH传输的P-CSI一般用高层信令(无线资源控制，Radio Resource Control，RRC)配置，基于PUCCH传输的SP-CSI也是用高层信令(RRC和/或MAC CE)配置或者激活，而基于PUSCH传输的SP-CSI或者A-CSI都是通过物理层信令(下行控制信息，Downlink control information，DCI)触发，而DCI一般在物理下行控制信道(Physical downlink control channel，PDCCH)上传输。在本申请实施例中，反馈波束参数信息组也可以称为传输波束参数信息 组或者发送波束参数信息组，比如把波束参数信息组承载在上行传输资源上进行反馈或者传输。所述上行传输资源和对应的CSI都是通过一个信道状态信息报告指示。在本申请实施例中，反馈一个CSI报告是指反馈所述CSI报告对应的波束参数信息组。
在一实施例中，基站通过高层信令和/或物理层信令给终端配置了NC个需要向基站反馈的CSI报告(CSI report)，每个CSI报告都有一个索引值(identity，ID)，称为CSI reportID，终端可以根据自己的计算能力或者处理能力，以及基站的要求选择NC个CSI报告中的MC个CSI报告。并根据上行反馈的资源，反馈该MC个CSI报告中的至少一个CSI报告，其中NC和MC为正整数，且MC≤NC。在一个示例中，需要反馈MC个CSI报告，但MC个报告中至少有两个报告的反馈资源是冲突的，两个报告的反馈资源冲突是指用于反馈两个报告对应的传输资源(比如PUCCH或者PUSCH)中至少有一个符号是相同的和/或至少有一个子载波是相同的。
下面，对波束参数信息的反馈、接收方法，通信节点，存储介质及其技术效果进行描述。
图2示出了一实施例提供的一种波束参数信息的反馈方法的流程示意图，如图2所示，本实施例提供的方法适用于第一通信节点。该方法包括如下步骤。
S110、接收N套参考信号配置信息和K套参考信号。
在一实施例中，接收K套参考信号的方法可以为：根据N套参考信号配置信息，接收K套参考信号。
第二通信节点传输了N套参考信号配置信息，传输了K套参考信号配置信息对应的K套参考信号。第一通信节点接收N套参考信号配置信息，并根据N套参考信号配置信息，接收了K套参考信号，K、N均为正整数、且K小于N。
K、N均为正整数、且K小于N，表示由于第二通信节点配置参考信号资源之间有冲突或者其它原因导致第二通信节点传输了数量小于N的K套参考信号，第一通信节点接收了K套参考信号。在实际的应用中，如果配置参考信号资源之间不存在冲突、也不存在其他影响因素，那么第二通信节点可以传输N套参考信号，第一通信节点接收了N套参考信号，即K等于N。当然在有的示例中，第二通信节点传输了N套参考信号，第一通信节点由于自身的能力或者信号不好等原因，只能有效接收K套参考信号。
在一实施例中，参考信号配置信息包括资源类别resourceType，这里资源类别定义了参考信号的时域传输特性，其中时域特性包括但不限于非周期(aperiodic)、周期(periodic)、半持续(semi-persistent)特性，分别表示传 输的参考信号是非周期传输的参考信号，周期传输的参考信号，或者半持续传输的参考信号，分别叫做周期参考信号，非周期参考信号，半持续参考信号。其中，周期参考信号或者半持续的参考信号都会通过高层信令配置一个周期和/或时隙偏置(slot offset)信息，这两个参数可以是联合编码的(比如通过高层信令periodicityAndOffset配置，通过获取这个参数，用户就可以知道周期或者半持续参考信号的传输周期，以及传输的时隙偏置)。在一个示例中，第二通信节点配置了N套参考信号配置信息。在这N套参考信号配置信息中，有K1个周期的参考信号，K2个非周期的参考信号，K3个半持续的参考信号。其中，K1，K2，K3为非负整数，且K1+K2+K3＝N。在一个示例中，第二通信节点配置了N套参考信号配置信息。在这N套参考信号配置信息中，资源的类别都是相同的，即，K1，K2，K3中有两个取值为零，比如都是周期的参考信号或都是非周期的参考信号或都是半持续的参考信号。在一个示例中，在这N套参考信号配置信息中，资源的类别至少有一个参考信号的资源类别和其它的另外一个参考信号的资源类别是不同的，比如K1，K2，K3中至少两个取值大于零。在一个示例中，第二通信节点需要配置和传输N＝4个CSI-RS，其中，CSI-RS可以是周期的，半持续的，非周期中的至少一种。比如在一种配置下，有两套周期的参考信号，一套非周期的参考信号，一套半持续的参考信号；在一种配置下，有三套半持续的参考信号，一套非周期的参考信号；在一种配置下，有两套周期的参考信号，两套非周期的参考信号；在一种配置下，有两套半持续的参考信号，两套周期的参考信号。
在一实施例中，一套参考信号包括以下之一：一个参考信号资源，一组参考信号资源，一个参考信号资源集合，一个参考信号资源配置对应的参考信号资源。例如，一套参考信号包括一个参考信号资源，比如一个CSI-RS resource，或一个SRS resource，或者一个SSB resource；在一实施例中，一套参考信号包括一组参考信号资源，比如一组CSI-RS resource，或一组SRS resource，或者一组SSB resource；在一实施例中，一套参考信号包括一个参考信号资源集合，比如一个CSI-RS resource set，或一个SRS resource set，或者一个SSB resource set；在一实施例中，一套参考信号包括一个参考信号资源配置对应的参考信号资源，比如一个CSI-RS resource config/setting对应的参考信号资源，或一个SRS resource config/setting对应的参考信号资源，或者一个SSB resource config/setting对应的参考信号资源。在这里，一组参考信号包括至少一个参考信号资源，多组参考信号资源可以在同一个参考信号资源集合中。
S120、根据K套参考信号，确定M个波束参数信息组。
S130、反馈M个波束参数信息组中的至少一个波束参数信息；K、M、N均为正整数、且K小于N。
在一些示例中，通信节点通过接收参考信号获得波束参数信息组，其中一个波束参数信息组可以包括一个或多个波束参数信息，一个波束参数信息对应一个波束。波束参数信息包括以下至少之一的参数：接收功率(比如L1-RSRP，RSRP，差分L1-RSRP，差分RSRP)，接收信干噪比(比如L1-SINR，SINR，差分L1-SINR，差分SINR)，BDRPM，RSRQ，以及波束对应的参考信号资源索引(CRI，SSBRI等)、波束的方向或角度，波束的索引(比如发送波束索引，接收波束索引，发送接收波束索引对)。第二通信节点在K个时隙发送用于波束参数信息测量的参考信号。第一通信节点在至少一个时隙分别接收K个时隙发送的参考信号，并根据接收的K个时隙发送的参考信号分别获得对应时隙的一个波束参数信息组Bi，i＝1，…，K。这里，K个时隙为参考时隙之前的时隙。在一实施例中，参考时隙包括以下之一：参考时隙为第一通信节点和第二通信节点约定的一个时隙，或者一个当前的时隙；或者第二通信节点指示的一个时隙；或者第二通信节点指示的一个时隙加一个固定偏置得到的时隙；或者第一通信节点收到第二通信节点指示信令的时隙加一个固定的偏置得到的时隙。
在一实施例中，第一通信节点不期望接收少于N套参考信号。也就是说，第二通信节点配置了N套参考信号配置信息，那么第一通信节点不期望第二通信节点传输少于N套参考信号配置信息对应的N套参考信号，或者第一通信节点期望能接收到N套参考信号。如果第一通信节点能收到N套参考信号，并根据N套参考信号获得其对应的N个波束参数信息组，根据N个波束参数信息组获取M个波束参数信息组。确定M个波束参数信息组的L个优选波束参数信息，M和N为正整数，且一般来说M不大于N，一个特例是M＝1。比如第二通信节点配置了N＝4套参考信号配置信息，那么就需要在一个或者多个时刻传输N＝4套参考信号。第一通信节点在一个或者多个时隙接收N＝4套参考信号。并通过获得的N＝4套参考信号通过一些列操作获得一个波束参数信息组。
根据N个波束参数信息组(比如第一波束参数信息组)获取M个波束参数信息组(比如第二波束参数信息组)。比如将N个波束参数信息组依次编码后输入到第一AI模块，第一AI模块输出M个波束参数信息组。在一些示例中，将波束参数信息编码包括但不限于以下之一，对波束参数信息组的元素进行归一化处理(比如将一个元素的范围归一化到区间[0，1]或[-0.5，0.5])，对波束参数信息组进行采样，对多个波束参数信息组进行联合操作。这里，N个波束参数信息组为参考时隙之前的波束参数信息组。M个波束参数信息组为参考时隙之后的波束参数信息组。N为大于1的整数，M为大于或等于1的整数。在一些示例中，根据N个波束参数信息组获取M个波束参数信息组，也可以根据其它非AI的方式获取，比如通过线性映射的方式，对N个波束参数信息组做滤波或者平均得到M个波束参数信息组。比如通过非线性映射的方式将N个波束 参数信息组处理为M个波束参数信息组。在有的示例中，N为大于M的正整数。在有的示例中，M是正整数，跟第一通信节点的能力有关，有的第一通信节点可以通过N个波束参数信息组获取1个波束参数信息组。有的第一通信节点可以根据N个波束参数信息组获取大于1个波束参数信息组。在一些示例中，根据N个波束参数信息组获取M个波束参数信息组，有以下之一的等价描述：根据N个波束参数信息组预测M个波束参数信息组；根据N个波束参数信息组处理为M个波束参数信息组；将N个波束参数信息组映射为M个波束参数信息组。
在一实施例中，还可以确定M个波束参数信息组对应的波束参数信息。包括，对第i个波束参数信息组，选择第i个波束参数信息组的波束参数信息最大的Li个波束信息参数所对应的波束为第i个波束信息组的优选波束。比如预测的第ni个时隙的优选波束参数。这里，Li和ni为正整数，i＝1，…，M。在一个示例中，所有的Li相同，比如为1，2，4，8等。在有的示例中，ni为参考时隙之后的时隙索引，随着i的增加升序排序。在一些示例中，将M个波束参数信息处理为M个CRI和/或L1-RSRP。在一些示例中，将M个波束参数信息处理为M个SSBRI和/或L1-RSRP。在一些示例中，将M个波束参数信息处理为M个CRI和/或L1-SINR。在一些示例中，将M个波束参数信息处理为M个SSBRI和/或L1-SINR。
在一实施例中，可以根据N个波束参数信息组获取M个波束参数信息组，并将M个波束参数信息组中的每个波束参数信息组分别处理为K0个波束参数信息。其中，1≤K0≤M。在有的示例中，也可以直接根据N个波束参数信息组获取K0个信道状态信息。即第一AI模块和第二AI模块直接合并为一个更大的AI模块。在一些示例中，可以直接根据N个接收的参考信号获取M个波束参数信息组或其对应的波束参数信息。
在一实施例中，虽然第一通信节点不期望接收少于N套参考信号，但是第二通信节点由于资源冲突或者其它的原因，只传输了N套参考信号中的K套参考信号，第一通信节点接收K套参考信号。第一通信节点可以根据K套参考信号，确定M个波束参数信息组。
在一实施例中，N套参考信号配置信息对应N套参考信号，K套参考信号为N套参考信号的一部分。在一实施例中，确定M个波束参数信息组可以采用AI的波束预测方式来实现，例如可以包括空域波束预测和时域波束预测，或者空时波束预测。对于空域波束预测，N套参考信号配置信息对应N套参考信号，N套参考信号属于同一个参考信号集合或者属于同一个参考信号配置。
在一实施例中，第一通信节点根据K套参考信号，确定M个波束参数信息 组的规则包括以下至少之一：
规则1)第一通信节点确定M个波束参数信息组为空。即第一通信节点不进行波束预测。
第二通信节点由于资源冲突或者其它的原因，只传输了N套参考信号中的K套参考信号，K小于N。第一通信节点接收K套参考信号，发现K套参考信号的套数比期望的N套参考信号少，无法通过K套参考信号对应的波束参数信息组获取参考时隙后的M个波束参数信息组。所以第一通信节点不进行通过K套参考信号对应的波束参数信息组获取M个波束参数信息组的操作。第一通信节点也不反馈参考时隙后的优选波束参数信息。
规则2)第一通信节点根据K套参考信号中的至少一套参考信号，确定M个波束参数信息组。

规则4)第一通信节点根据K套参考信号，确定K个第一波束参数信息组；将K个第一波束参数信息组处理为N个第二波束参数信息组；根据N个第二波束参数信息组，获取M个波束参数信息组(比如第三波束参数信息组)，M为正整数。
第二通信节点由于资源冲突或者其它的原因，只传输了N套参考信号中的K套参考信号，K小于N。第一通信节点接收K套参考信号，发现K套参考信号的套数比期望的N套参考信号少，第一通信节点根据自身的处理能力，确定是否可以根据K个波束参数信息组获取M个波束参数信息组。如果可以，第一通信节点根据K套参考信号，确定K个第一波束参数信息组；将K个第一波束参数信息组处理为N个第二波束参数信息组；根据N个第二波束参数信息组，获取M个波束参数信息组，否则，不进行通过K套参考信号对应的波束参数信息组获取M个波束参数信息组的操作，或者根据约定的方式获取K个波束参数信息组中的至少一个波束参数信息组对应的优选波束参数信息。
在一示例中，第一波束参数信息组包括的元素个数小于第二波束参数信息组包括的元素个数，第二波束参数信息组包括的元素个数小于或者等于波束参数信息组(比如第三波束参数信息组)包括的元素个数。
在一实例中，第一通信节点通过补零的方式，对K个第一波束参数信息组补零操作，获取N个第二波束参数信息组。比如根据传输K个第一波束参数信息组对应的参考信号的时隙，确定接收了N个波束参数信息组中的哪几个波束参数信息组，并对没有接收到的参考信号对应的波束参数信息组补零矩阵，一个零矩阵为L0*1维度的向量，或者为Lv*Lh维度的矩阵，其中L0，Lv，Lh为正整数，LvxLh＝L0分别表示为波束参数信息组中的元素个数，或者波束参数信息组中波束参数信息对应的水平波束和垂直波束的个数。

图3示出了一实施例提供的一种波束参数信息的接收方法的流程示意图，如图3所示，本实施例提供的方法适用于第二通信节点。该方法包括如下步骤。
S210、发送N套参考信号配置信息和K套参考信号。
在一实施例中，发送K套参考信号的方法可以为：根据N套参考信号配置信息，发送K套参考信号。
第二通信节点传输了N套参考信号配置信息，传输了K套参考信号配置信息对应的K套参考信号。第一通信节点接收N套参考信号配置信息，并根据N套参考信号配置信息，接收了K套参考信号，K、N均为正整数、且K小于N。
K、N均为正整数、且K小于N，表示由于第二通信节点配置参考信号资源之间有冲突或者其它原因导致第二通信节点传输了数量小于N的K套参考信号，第一通信节点接收了K套参考信号。在实际的应用中，如果配置参考信号资源之间不存在冲突、也不存在其他影响因素，那么第二通信节点可以传输N套参考信号，第一通信节点接收了N套参考信号，即K等于N。当然在有的示 例中，第二通信节点传输了N套参考信号，第一通信节点由于自身的能力或者信号不好等原因，只能有效接收K套参考信号。
在一实施例中，参考信号配置信息包括资源类别resourceType，这里资源类别定义了参考信号的时域传输特性，其中时域特性包括但不限于非周期(aperiodic)、周期(periodic)、半持续(semi-persistent)特性，分别表示传输的参考信号是非周期传输的参考信号，周期传输的参考信号，或者半持续传输的参考信号，分别叫做周期参考信号，非周期参考信号，半持续参考信号。其中，周期参考信号或者半持续的参考信号都会通过高层信令配置一个周期和/或时隙偏置(slot offset)信息，这两个参数可以是联合编码的(比如通过高层信令periodicityAndOffset配置，通过获取这个参数，用户就可以知道周期或者半持续参考信号的传输周期，以及传输的时隙偏置)。在一个示例中，第二通信节点配置了N套参考信号配置信息。在这N套参考信号配置信息中，有K1个周期的参考信号，K2个非周期的参考信号，K3个半持续的参考信号。其中，K1，K2，K3为非负整数，且K1+K2+K3＝N。在一个示例中，第二通信节点配置了N套参考信号配置信息。在这N套参考信号配置信息中，资源的类别都是相同的，即，K1，K2，K3中有两个取值为零，比如都是周期的参考信号或都是非周期的参考信号或都是半持续的参考信号。在一个示例中，在这N套参考信号配置信息中，资源的类别至少有一个参考信号的资源类别和其它的另外一个参考信号的资源类别是不同的，比如K1，K2，K3中至少两个取值大于零。在一个示例中，第二通信节点需要配置和传输N＝4个CSI-RS，其中，CSI-RS可以是周期的，半持续的，非周期中的至少一种。比如在一种配置下，有两套周期的参考信号，一套非周期的参考信号，一套半持续的参考信号；在一种配置下，有三套半持续的参考信号，一套非周期的参考信号；在一种配置下，有两套周期的参考信号，两套非周期的参考信号；在一种配置下，有两套半持续的参考信号，两套周期的参考信号。
在一实施例中，一套参考信号包括以下之一：一个参考信号资源，一组参考信号资源，一个参考信号资源集合，一个参考信号资源配置对应的参考信号资源。例如，一套参考信号包括一个参考信号资源，比如一个CSI-RS resource，或一个SRS resource，或者一个SSB resource；在一实施例中，一套参考信号包括一组参考信号资源，比如一组CSI-RS resource，或一组SRS resource，或者一组SSB resource；在一实施例中，一套参考信号包括一个参考信号资源集合，比如一个CSI-RS resource set，或一个SRS resource set，或者一个SSB resource set；在一实施例中，一套参考信号包括一个参考信号资源配置对应的参考信号资源，比如一个CSI-RS resource config/setting对应的参考信号资源，或一个SRS resource config/setting对应的参考信号资源，或者一个SSB resource config/setting 对应的参考信号资源。在这里，一组参考信号包括至少一个参考信号资源，多组参考信号资源可以包括在同一个参考信号资源集合中。
S220、接收至少一个波束参数信息，波束参数信息是第一通信节点根据K套参考信号确定出的M个波束参数信息组中的至少一个波束参数信息；K、M、N均为正整数、且K小于N。
在一实施例中，第二通信节点不期望发送少于N套参考信号。也就是说，第二通信节点配置了N套参考信号配置信息，那么第二通信节点不期望传输少于N套参考信号配置信息对应的N套参考信号。
在一实施例中，N套参考信号配置信息对应N套参考信号，K套参考信号为N套参考信号的一部分。在一实施例中，确定波束参数信息组可以采用AI的波束预测方式来实现，例如可以包括空域波束预测和时域波束预测，或者空时波束预测。对于空域波束预测，N套参考信号配置信息对应的N套参考信号属于同一个参考信号集合或者同一个参考信号配置。
