在无线通信领域，路径损耗会随着载频的升高而增加，特别是在高频通信中，路径损耗问题对性能的影响会更加突出。为了保证覆盖，一般会使用多阵子阵列天线以获得波束赋型增益，用波束赋型增益来弥补路径损耗的影响。而为了获得波束增益，需要根据用户终端所处的信道选择与用户终端信道匹配的最佳波束。

具体实施方式
下文中将结合附图对本申请的实施例进行详细说明。
在无线通信技术中，提出了通过多阵子阵列天线进行多波束赋型，从而提高波束增益，弥补路径损耗的方案。如图1所示，图1为一实施例提供的多波束传输示意图，在图1中，基站和终端之间分别通过多阵子阵列天线实现了多波束。为了获得波束增益，需要根据终端所处的信道选择与终端信道匹配的最佳波束。采用的波束选择方法是基于RSRP进行选择的，但由于基站和终端进行了多波束赋型，同频的其他波束会对所需选择的波束产生干扰，从而影响波束的选择。因此就需要对波束的信道信息和干扰信息进行准确地测量，从而根据测量结果实现波束的准确选择。
图2为一实施例提供的一种信道测量方法的流程图，如图2所示，本实施例提供的方法包括如下步骤。
步骤S2010，配置测量资源信息，测量资源信息用于获取信道状态信息，其中，测量资源信息包括N个信道测量资源信息和M个干扰测量资源信息，N和M为正整数。
本实施例提供的信道测量方法应用于无线通信系统中的基站设备，简称基站。基站为终端分配各种传输资源，以及向终端发送各种配置信息，以使终端确定传输所使用的资源和所需执行的各种测量或传输指令。
在基站和终端通过多阵子阵列天线实现多波束赋型时，终端需要对基站赋型的多个波束进行测量，并向基站传输测量到的各波束的状态，从而使基站选 择增益最大的波束作为最佳波束与终端建立信道进行数据传输。终端对各波束的RSRP进行测量并反馈，也即将接收功率最大的波束作为终端所使用的的波束，但这样没有考虑到同频的其他波束的干扰，从而可能影响波束的选择。
为了解决上述问题，在本实施例中，基站配置测量资源信息，测量资源信息用于获取信道状态信息。其中，测量资源信息包括N个信道测量资源(Channel Measurement Resource，CMR)信息和M个干扰测量资源(Interference Measurement Resource，IMR)信息，N和M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。其中N个CMR信息用于使终端对各波束的信道状态进行测量，M个IMR信息用于使终端对各波束所受到的干扰进行测量。
CMR信息(CMR setting或者CMR config)包括信道测量资源集合(CMR set)和/或信道测量资源子集合(CMR sub set)，一个信道测量资源集合包括至少一个信道测量资源子集合，一个信道测量资源集合包括至少一个信道测量资源，一个信道测量资源子集合包括至少一个信道测量资源。其中，信道测量资源表示用于信道测量的参考信号资源，包括但不限于信道状态信息-参考信号(Channel State Information-Reference Signal，CSI-RS)资源、同步信号块(Synchronization Signals Block，SSB)资源、物理广播信道(Physical Broadcast Channel，PBCH)资源、同步广播块/物理广播信道(SSB/PBCH)资源，上行探测参考信号(Sounding reference signal，SRS)资源。其中CSI-RS资源主要是指非零功率信道状态信息-参考信号(Non Zero Power Channel State Information-Reference Signal，NZP-CSI-RS)资源。当信道测量资源集合只包括一个信道测量资源子集合时，信道测量资源信息为信道测量资源集合，否则可以是信道测量资源子集合。
在本申请一实施例中，每个信道测量资源子集合内的信道测量资源具有相同的空间特性，和/或不同信道测量资源子集合间的信道测量资源具有不同的空间特性。
一个具体的信道测量资源配置方法如下：第l个信道测量资源集合根据预定的方式，比如空间特性分成Kl个信道测量资源子集合，Kl为正整数，l＝1，…，N。其中，信道测量资源子集合中包括至少一个信道测量资源，信道测量资源子集合内包括的信道测量资源有相同的空间特性，而不同信道测量资源子集合间的信道测量资源有不同的空间特性。比如将一个信道测量资源集合分成K个子集合，第i个信道测量资源子集合包括Li个信道测量资源，其中第Li个信道测量资源子集合里的信道测量资源都有相同的空间特性，而第Li个信道测量资源子集合里的一个信道测量资源和第Lj个信道测量资源子集合里的一个信道测量 资源有不同的空间特性，i，j＝1，…，K，且i不等于j。这里，每个信道测量资源集合包含的信道测量资源子集合的数目可以不同，也可以相同，每个信道测量资源子集合包含的信道测量资源数目也可以相同或者不同。这里还可以根据高层信令配置信道测量资源集合中的信道测量资源子集合。
信道测量资源集合和/或信道测量资源子集合包含的信道测量资源标识(Identify，ID)是统一排序的或者整体排序的，所以信道测量资源集合和/或信道测量资源子集合包含的信道测量资源ID是唯一编号的，不会有重复的ID。
IMR信息(IMR setting或者IMR config)包括干扰测量资源集合(IMR set)、干扰测量资源子集合(IMR sub set)、干扰测量资源子子集合(IMR sub sub set)中的至少一种。一个干扰测量资源集合包括至少一个干扰测量资源子集合，一个干扰测量资源集合包括至少一个干扰测量资源，一个干扰测量资源子集合包括至少一个干扰测量资源子子集合，一个干扰测量资源子子集合包括至少一个干扰测量资源。其中，干扰测量资源表示用于干扰测量的参考信号资源，包括但不限于用于测量干扰的非零功率信道状态信息-参考信号(Non Zero Power Channel State Information-Reference Signal，NZP-CSI-RS)资源，信道状态信息干扰测量(Channel State Information-Interference Measurement，CSI-IM)资源，零功率信道状态参考信号(Zero Power Channel State Information-Reference Signal，ZP-CSI-RS)资源。其中，NZP-CSI-RS干扰测量资源中会配置序列资源即配置测量参考信号，根据NZP-CSI-RS干扰测量资源中的测量参考信号得到干扰的功率。CSI-IM干扰测量资源中不会配置序列资源即也不配置测量参考信号，CSI-IM干扰测量资源上接收的功率即为干扰的功率，一般来说，也没有准共位置之类的参数配置。例如：IMR信息包括M个干扰测量资源集合，M个信息干扰测量资源集合包括的所有干扰测量资源子集合的个数之和为M1，和/或，M个干扰测量资源集合包括的所有干扰测量资源子子集合的个数之和为M2。那么M1和/或M2大于1。当干扰测量资源集合只包括一个干扰测量资源子集合时，干扰测量资源信息为干扰测量资源集合，否则可以是干扰测量资源子集合。如果干扰测量资源子集合被分成了干扰测量资源子子集合，那么干扰测量资源信息为干扰测量资源子子集合。
在本申请一实施例中，每个干扰测量资源子集合内的干扰测量资源具有相同的空间特性，和/或不同干扰测量资源子集合间的干扰测量资源具有不同的空间特性。
一个具体的干扰测量资源配置方法如下：干扰测量资源信息包括干扰测量资源集合和/或干扰测量资源子集合和/或干扰测量资源子子集合；当干扰测量资源信息为干扰测量资源集合时，第l个干扰测量资源集合根据空间特性分成Ol 个干扰测量资源子集合，Ol为正整数，l＝1，…，M。其中，干扰测量资源子集合中包括至少一个干扰测量资源，干扰测量资源子集合内包括的干扰测量资源有相同的空间特性，而不同干扰测量资源子集合间的干扰测量资源有不同的空间特性。比如将这个干扰测量资源集合分成O个子集合，第i个干扰测量资源子集合包括Li个IMR，其中第Li个干扰测量资源子集合里的干扰测量资源都有相同的空间特性，而第Li个干扰测量资源子集合里的一个干扰测量资源和第Lj个干扰测量资源子集合里的一个干扰测量资源有不同的空间特性，i，j＝1，…，K，且i不等于j。这里，每个干扰测量资源集合保护的干扰测量资源子集合的数目可以不同，也可以相同，干扰测量资源子集合可以分成至少一个干扰测量资源子子集合。
干扰测量资源集合和/或干扰测量资源子集合包含的干扰测量资源ID是统一排序的或者整体排序的，所以干扰测量资源集合和/或干扰测量资源子集合包含的干扰测量资源ID是唯一编号的，不会有重复的ID。
例如：N个信道测量资源信息包括以下之一的具体配置：A1：N个信道测量资源集合，每个信道测量资源集合包括至少一个信道测量资源，每个信道测量资源集合只有一个信道测量资源子集合。A2：N＝1个信道测量资源集合，每个信道测量资源集合被分成K个信道测量资源子集合，每个信道测量资源子集合包括至少一个信道测量资源子子集合。A3：N>1个信道测量资源集合，第i个信道测量资源集合被分成Ki个信道测量资源子集合，每个信道测量资源子集合包括至少一个信道测量资源，i＝1，…，N。
M个干扰测量信息包括以下之一的具体配置：B1：M个干扰测量资源集合，每个干扰测量资源集合包括至少一个干扰测量资源，每个干扰测量资源集合只有一个干扰测量资源子集合。B2：M＝1个干扰测量资源集合，每个干扰测量资源集合被分成O个干扰测量资源子集合，每个干扰测量资源子集合包括至少一个干扰测量资源，或，每个干扰测量资源子集合被划分成至少一个干扰测量资源子子集合。B3：M>1个干扰测量资源集合，第i个干扰测量资源集合被分成Oi个干扰测量资源子集合，每个干扰测量资源子集合包括至少一个干扰测量资源，i＝1，…，M，或，每个干扰测量资源子集合被划分成至少一个干扰测量资源子子集合。
信道测量资源信息的任何一个配置A1、A2、A3中的一个信道测量资源集合或者信道测量资源子集合可以与干扰测量资源信息的任何一个配置B1、B2、B3中的一个干扰测量资源集合或者干扰测量资源子集合，或干扰测量资源子子集合关联。在一实施例中，A1中的一个信道测量资源集合与B1中的一个干扰测量资源集合关联；A2中的一个信道测量资源子集合与B2中的一个干扰测量 资源子集合和/或干扰测量资源子子集合关联；A3中的一个信道测量资源子集合与B3中的一个干扰测量资源子集合和/或干扰测量资源子子集合关联；A2中的一个信道测量资源子集合与B3中的一个干扰测量资源子集合和/或干扰测量资源子子集合关联。具体哪个信道测量资源子集合(集合)与哪个干扰测量资源子集合(集合)关联或对应，由预先定义，或者基站配置，或者信令确定，信令包括物理层信令和/或高层信令。
图3为一实施例提供的CMR和IMR资源的关联关系示意图。
步骤S2020，发送测量资源信息。
在配置了测量资源信息后，基站即可向终端发送测量资源信息。基站可以通过任一种下行控制信道向终端发送测量资源信息。
当终端接收到测量资源信息后，即可根据测量资源信息中包括的N个信道测量资源信息和M个干扰测量资源信息分别对信道和干扰进行测量。
终端接收基站配置的信道测量资源信息和干扰测量资源信息，并获取信道测量资源信息和干扰测量资源信息的关联信息，并用信道测量资源信息和干扰测量资源信息以及它们的关联关系计算信道状态信息。比如用第i个信道测量资源子集合的信道测量资源和第j个干扰测量资源子集合的干扰测量资源计算信道状态信息，其中，第i个信道测量资源子集合(集合)和第j个干扰测量资源子集合(集合)具有关联关系，i＝1，…，N，j＝1，…，M，N和M分别为信道测量资源子集合(集合)和干扰测量资源子集合(集合)的个数。
可选地，基站在发送测量资源信息后，还可以接收终端发送的信道状态信息，信道状态信息包括信道相关参数和/或干扰相关参数。当基站接收到终端发送的信道状态信息，即可确定基站发出的各波束对于终端的信道状态和干扰情况，从而基站可以选择出最优波束与终端建立通信连接实现数据传输。
基站接收到终端发送的测量到的各种参数，即信道状态信息，信道状态信息包括信道相关参数和/或干扰相关参数。其中信道相关参数是终端响应于信道测量资源而测量出的参数，干扰相关参数是终端响应于干扰测量资源而测量出的参数。

信道状态信息-参考信号资源指示(CSI-RS Resource Indicator，CRI)取值为i表示第i个CSI-RS资源，i＝0，1，...N，N为CSI-RS资源的个数。而同步信号块资源指示(SSBRI，Synchronization Signals Block Resource Indicator)取值为i表示第i个SSB和/或PBCH资源，i＝0，1，...N1，N1为SSB的资源的个数。干扰测量资源指示(IMRI，Interference Measurement Resource)取值为i表示第i个IMR资源，i＝0，1，...N1，N1为IMR的资源的个数。
本实施例提供的信道测量方法，首先配置测量资源信息，测量资源信息用于获取信道状态信息，其中，测量资源信息包括N个信道测量资源信息和M个干扰测量资源信息，N和M为正整数，然后向终端发送测量资源信息，使得终端能够对基站生成的多个波束的信道情况和干扰情况进行测量，能更好地反映干扰在波束管理中的作用，从而能选择更优的波束以提高系统性能。
在一实施例中，配置测量资源信息时，还可以根据预设规则确定N个信道测量资源信息和M个干扰测量资源信息的关联关系。N个信道测量资源信息和M个干扰测量资源信息的关联关系可以预设于基站中，也可以预设于终端中。若关联关系预设于基站中，则基站在确定了关联关系后，向终端发送第一信令，第一信令用于确定N个信道测量资源信息和M个干扰测量资源信息的关联关系。N个信道测量资源信息和M个干扰测量资源信息的关联关系也可称为关联关系。这里的关联关系包括如下至少一种：一个参数的取值根据另一个参数的取值得到；一个参数的取值范围根据另一个参数的取值或者取值范围得到；两个参数的某些取值组合不能同时出现；参数1的配置信息中配置为参数1关联 的参数2；通过第一信令和/或预定规则确定两个参数之间的关系。

N个信道测量资源信息和M个干扰测量资源信息的关联关系包括至少以下之一：信道测量资源信息中的一个信道测量资源和干扰测量资源信息中的一个干扰测量资源有关联关系；信道测量资源信息中的一个信道测量资源子集合和干扰测量资源信息中的一个干扰测量资源子集合有关联关系；信道测量资源信息中的一个信道测量资源子集合和干扰测量资源信息中的一个干扰测量资源子子集合有关联关系；信道测量资源信息中的一个信道测量资源集合和干扰测量资源信息中的一个干扰测量资源集合有关联关系。其中，具有关联关系的信道测量资源信息和干扰测量资源信息能同时发送或具有关联关系的信道测量资源信息和干扰测量资源信息具有相同的空间特性。
空间特性包括以下至少之一：准共位置(quasi co-location，QCL)，传输配置指示(transmission configuration indication，TCI)，传输配置状态(transmission configuration state)，QCL类型D(QCL Type D)，接收空间特性，发送空间特性，接收波束组，发送波束组，接收波束，发送波束，空间接收参数(Spatial Rx  Parameter)。空间特性相同是指上述至少空间特性参数之一取值相同。在一实施例中，空间特性主要包括QCL Type D或空间接收参数(Spatial Rx Parameter)。
两个参考信号之间的关于一类准共址参数满足准共址关系包括以下至少之一：一个参考信号的准共址参数可以根据另一个参考信号的准共址参数获取；两个参考信号的关于一类准共址参数的准共址参考信号相同，比如，CSI-RS1关于空间接收参数的准共址参考信号为CSI-RS3，CSI-RS2关于空间接收参数的准共址参考信号为CSI-RS3，则CSI-RS1和CSI-RS2关于空间接收参数满足准共址关系。
在一实施例中，干扰测量资源信息的空间特性由与干扰测量资源信息关联的信道测量资源信息的空间特性确定。这里的干扰测量资源信息主要包括至少以下之一：NZP CSI-RS资源，NZP CSI-RS资源集合，NZP CSI-RS资源子集合，NZP CSI-RS资源子子集合。
在一实施例中，干扰测量资源信息的空间特性对应的参考导频由干扰测量资源信息关联的信道测量资源信息的空间特性对应的参考导频确定。比如，信道测量资源信息的空间特性取值为A，对应的空间特性参考导频为B，那么与之关联的干扰测量资源信息的空间特性的取值也为A，对应的空间特性参考导频也为B。即干扰测量资源信息的空间特性取值和与之关联的信道测量资源信息的空间特性取值相同，对应的空间特性参考导频相同，具体地比如信道测量资源子集合的空间特性和与这个信道测量资源子集合关联的(对应的)干扰测量资源子集合或信道干扰资源子子集合具有相同的空间接收参数。
在一实施例中，信道测量资源信息和干扰测量资源信息包括重复参数(repetition)。
干扰测量资源信息和干扰测量资源信息的重复参数由以下任一种方式确定：干扰测量资源集合的重复参数由干扰测量资源集合关联的信道测量资源集合的重复参数确定；干扰测量资源子集合的重复参数由干扰测量资源子集合关联的信道测量资源子集合的重复参数确定；干扰测量资源子子集合的重复参数由干扰测量资源子集合关联的信道测量资源子集合的重复参数确定；干扰测量资源集合的重复参数和干扰测量资源集合关联的信道测量资源集合的重复参数由独立的高层参数确定；干扰测量资源子集合的重复参数和干扰测量资源子集合关联的信道测量资源子集合的重复参数由独立的高层参数确定；干扰测量资源子子集合的重复参数由干扰测量资源子子集合关联的信道测量资源子集合的重复参数由独立的高层参数确定。
比如，信道测量资源信息的重复参数取值为on，那么与之关联的干扰测量资源信息的重复参数取值为on。例如，根据信道测量资源子集合的重复参数取 值确定干扰测量资源子集合和/或干扰测量资源子子集合的重复参数取值；根据信道测量资源的重复参数取值确定干扰测量资源子集合和/或干扰测量资源子子集合的重复参数取值。
由于基站在向终端发送测量资源信息时，并不知道终端需要传输的信道状态信息的总比特数目，因此基站无法准确调度上行资源。另外，终端在传输信道状态信息时，还需要向基站传输除了信道相关参数和干扰相关参数外的信道状态信息(Channel State Information，CSI)相关的参数，混合自动重传(Hybrid automatic repeat request，HARQ)等相关参数。其中信道相关参数和干扰相关参数外的CSI(在本文中把信道相关参数和干扰相关参数外的CSI参数统称为信道质量相关参数)包括但不限于以下至少之一，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资源指示(CSI-RS resource indicator，CRI)，层指示(layer indicator，LI)，秩指示(rank indicator，RI)。当终端在完成信道状态信息的检测后，当上行资源无法传输所有信道状态信息时，需要对部分信道状态信息进行舍弃。
那么就需要对信道状态信息进行优先级排序，其中CSI的相关参数的优先级包括以下至少之一：
IQI的优先级不高于RSRP的优先级。
IMRI的优先级不高于CRI或SSBRI的优先级。
IMRI的优先级不低于RI的优先级。
IMRI的优先级不低于PMI的优先级。
IMRI的优先级不低于LI的优先级。
IMRI的优先级不低于CQI的优先级。
IMRI的优先级高于IQI和/或Differential IQI的优先级。
IMRI的优先级高于RSRP和/或Differential RSRP的优先级。
RSRP的优先级不低于IQI和/或Differential IQI的优先级。
Differential IQI的优先级不高于Differential RSRP的优先级。
IQI和/或Differential IQI的优先级高于RI和/或LI的优先级；
IQI和/或Differential IQI的优先级高于PMI和/或CQI的优先级。
终端根据上述的优先级对CSI相关的参数进行编码，并有可能在编码率要求达不到系统要求时，对优先级低的参数进行舍弃直到达到系统编码率的要求。基站根据上述的优先级对CSI相关参数进行解码那么接收终端发送的信道状态 信息，包括如下情况至少之一：
当IMRI由CRI确定时，接收CRI；
当IMRI由SSBRI确定时，接收SSBRI；
接收至少一个CRI、RSRP和/或差分RSRP；
接收至少一个CRI、IQI和/或差分IQI；
接收至少一个CRI、RSRP和/或差分RSRP、IQI和/或差分IQI；
接收至少一个SSBRI、RSRP和/或差分RSRP；
接收至少一个SSBRI、IQI和/或差分IQI；
接收至少一个SSBRI、RSRP和/或差分RSRP、IQI和/或差分IQI；
接收至少一个IMRI、RSRP和/或差分RSRP；
接收至少一个IMRI、IQI和/或差分IQI；
接收至少一个IMRI、RSRP和/或差分RSRP、IQI和/或差分IQI；
接收至少一个CRI、至少一个IMRI、RSRP和/或差分RSRP；
接收至少一个CRI、至少一个IMRI、IQI和/或差分IQI；
接收至少一个CRI、至少一个IMRI、RSRP和/或差分RSRP、IQI和/或差分IQI。
在一实施例中，接收终端发送的信道状态信息，可以接收终端通过上行资源传输的信道状态信息，其中信道状态信息中的信道相关参数和干扰相关参数需要采用一定的编码方式进行编码处理，那么基站就可以采用与终端对应的解码方式实现解码。上行资源包括物理上行信道，高层信令。其中，物理上行信道至少包括以下之一：物理上行共享信道(Physical uplink shared channel，PUSCH)、物理上行控制信道(Physical uplink control channel，PUCCH)，物理随机接入信道(Physical random-access channel，PRACH)。高层信令包括无线资源控制(Radio Resource Control，RRC)信令和媒体接入控制层控制单元(Media Access Control control element，MAC CE)信令。这里的上行资源都可以用于传输信道状态信息。
为了便于描述在一个报告中如何传输信道状态信息，需要先对的信道状态信息进行编码。在编码前需要确定信道状态信息各个变量的比特数目。首先，当前标准中已经定了CRI、SSBRI、RSRP等参数的比特数目，如表1所示。
表1
Figure PCTCN2020086141-appb-000001
其中，
Figure PCTCN2020086141-appb-000002
为CSI-RS所在的CSI-RS资源集合中的CSI-RS个数，
Figure PCTCN2020086141-appb-000003
为SS/PBCH对应的SS/PBCH资源集合中的SS/PBCH块个数。
表2和表3示出IMRI、IQI、Differential IQI的比特数目。其中表2不包括IMRI，因为IMRI可能由CRI隐含传输。
表2
Figure PCTCN2020086141-appb-000004
表3
Figure PCTCN2020086141-appb-000005
其中，
Figure PCTCN2020086141-appb-000006
为干扰测量资源子集合的个数和/干扰测量资源集合的个数，a，b为正整数。例如a＝7、b＝4。
或者所有的信道状态信息的位宽合并为一个表4。
表4
Figure PCTCN2020086141-appb-000007
需要说明的是，如果IMRI由CRI或者SSBRI隐含指示，那么表4用表5的形式替换：
表5
Figure PCTCN2020086141-appb-000008
在知道信道状态信息的传输比特后，以及它们的优先级后就可以对信道状态信息进行编码，并将编码后的信道状态信息在上行资源中传输给基站。
对信道状态信息进行编码的具体方法可以采用如下三种方式进行：
1)信道状态信息中的信道相关参数和干扰相关参数在一个编码块里联合编码。
此时，上行资源为PUCCH，信道状态信息中的信道相关参数和干扰相关参 数联合编码，具体的编码方式如表6所示。
表6
Figure PCTCN2020086141-appb-000009
2)信道状态信息中的信道相关参数和干扰相关参数在两个编码块里独立编码。
此时，上行资源为PUCCH，信道状态信息中的信道相关参数和干扰相关参数独立编码，如图表7和表8所示，其中表7为信道相关参数的编码方式，表8为干扰相关参数的编码方式。
表7

Figure PCTCN2020086141-appb-000011
表8
Figure PCTCN2020086141-appb-000012
3)信道状态信息包括RSRP和IQI时，RSRP在第一部分编码块中编码，IQI在第二部分编码块的宽带或子带部分编码；信道状态信息包括差分RSRP和IQI时，差分RSRP在第一部分编码块中编码，IQI在第二部分编码块的宽带或子带部分编码；信道状态信息包括RSRP和差分IQI时，RSRP在第一部分编码块中编码，差分IQI在第二部分编码块的宽带或子带部分编码；信道状态信息包括差分RSRP和差分IQI时，差分RSRP在第一部分编码块中编码，差分IQI在第二部分编码块的宽带或子带部分编码；信道状态信息包括IQI但不包括RSRP和/或差分RSRP时，IQI在第一部分编码块中编码；信道状态信息包括差分IQI但不包括RSRP和/或差分RSRP时，差分IQI在第一部分编码块中编码；其中，第一部分编码块的传输优先级高于第二部分编码块的传输优先级。也就是终端 完成编码后，优先传输第一部分编码块中编码的信息。
其中，CRI、SSBRI、IMIR至少之一在第一部分编码块中编码，如表9所示，IQI、RSRP、Differential IQI、Differential RSRP至少之一在第二部分编码块中编码，如表10所示。
表9
Figure PCTCN2020086141-appb-000013
表10
Figure PCTCN2020086141-appb-000014
需要说明的是，如果IQI和RSRP只有一个存在时，可以只在第一部分编码块中编码。终端通过表6-表10的方式对信道状态信息进行编码，如果还存在其 他CSI参数也可以一起进行编码，将编码后的数据进行调制，资源映射等操作后在PUCCH上传输给基站，基站在PUCCH资源上接收信道状态信息，并通过解调、解码等一系列操作获得波束赋形相关的参数。
另外，如果在PUSCH上传输，那么除了表6-表10外还可能存在其他编码方式，例如表11-表13所示的编码形式。其中表11中，所有的信道状态信息在CSI报告的第一部分编码块里编码；表12中，以下参数至少之一在CSI报告的第一部分编码块里编码，CRI、SSBRI、IMRI、RSRP，Differential RSRP；表13表示以下参数至少之一在CSI报告的第二部分编码块的宽带部分进行编码：IQI和Differential IQI。
表11
Figure PCTCN2020086141-appb-000015
表12
Figure PCTCN2020086141-appb-000016
Figure PCTCN2020086141-appb-000017
表13
Figure PCTCN2020086141-appb-000018
即，对于PUSCH传输，包括如下特征之一：
信道相关参数和干扰相关参数都在CSI报告的第一部分编码块联合编码，或CRI、SSBRI、IMR以及RSRP、Differential RSRP至少之一在CSI报告的第一部分编码块编码，而IQI、Differential IQI至少之一在CSI报告的第一部分编码块宽带部分或CSI报告的第一部分编码块子带部分编码。
终端通过表6-表13的方式对信道状态信息进行编码，如果还存在其它CSI参数也可以一起进行编码，将编码后的数据进行调制，资源映射等操作后在PUSCH上传输给基站，基站在PUSCH资源上接收信道状态信息，并通过解调、解码等一系列操作获得波束赋形相关的参数。
需要说明的是，终端也可以通过表6-表13的方式对信道状态信息进行编码，并将一些信道状态信息在PUCCH上传输，而另外一部分信道状态信息在PUSCH上或者高层信令上传输。
需要说明的是，表6-表13只是对信道状态信息编码的一些实施例，也可以有其它的对信道状态信息进行任意组合和拆分的编码方式，这里不一一例举。
图4为一实施例提供的另一种信道测量方法的流程图，如图4所示，本实施例提供的方法包括如下步骤。
步骤S4010，接收测量资源信息，其中，测量资源信息包括N个信道测量 资源信息和M个干扰测量资源信息，N和M为正整数。
本实施例提供的信道测量方法应用于无线通信系统中的终端设备，简称终端。终端根据基站分配的传输资源完成数据传输，并且接收基站发送的各种配置信息，根据各种配置信息确定传输所需资源，并执行各种配置信息所指示的测量指令。
在基站和终端通过多阵子阵列天线实现多波束赋型时，终端需要对基站赋型的多个波束进行测量，并向基站传输测量到的各波束的状态，从而使基站选择增益最大的波束作为最佳波束与终端建立信道进行数据传输。终端对各波束的RSRP进行测量并传输，也即将接收功率最大的波束作为终端所使用的的波束，但这样没有考虑到同频的其他波束的干扰，从而可能影响波束的选择。
为了解决上述问题，在本实施例中，终端接收基站发送的测量资源信息，其中，测量资源信息包括N个信道测量资源信息和M个干扰测量资源信息，N和M为正整数。
测量资源信息，以及测量资源信息中N个信道测量资源信息和M个干扰测量资源信息的具体含义和相互关系在图2所示实施例中已经详细说明，此处不再赘述。
步骤S4020，根据测量资源信息获取信道状态信息，信道状态信息包括信道相关参数和/或干扰相关参数。
终端接收到测量资源信息后，即可根据测量资源信息中包括的N个信道测量资源信息和M个干扰测量资源信息分别对信道和干扰进行测量，获取信道状态信息，信道状态信息包括信道相关参数和/或干扰相关参数。
信道状态信息的含义和信道相关参数和干扰相关参数的关系在图2所示实施例中已经详细说明，此处不再赘述。
步骤S4030，向基站传输信道状态信息。
终端在获取到信道状态信息后，向基站传输信道状态信息。基站接收到终端发送的测量到的各种参数，即信道状态信息，信道状态信息包括信道相关参数和/或干扰相关参数。其中信道相关参数是终端响应于信道测量资源而测量出的参数，干扰相关参数是终端响应于干扰测量资源而测量出的参数。当基站接收到终端发送的信道状态信息，即可确定基站发出的各波束对于终端的信道状态和干扰情况，从而基站可以选择出最优波束与终端建立通信连接实现数据传输。
对于图4所示实施例，信道测量资源和干扰测量资源的组成、相互关系，信道相关参数和干扰相关参数的组成，相互关系，基站如何向基站传输信道状 态信息，以及如何编码信道状态信息的具体方法已经在上述实施例中进行了详细说明，此处不再赘述。
需要说明的是，本申请实施例中，仅以基站配置测量资源信息，向终端测量资源信息后接收终端发送的信道状态信息为例进行了说明，也即通过上行资源传输信道状态信息。但实际上，由于终端也支持多波束赋形，对于基站和终端而言，同样可以通过下行资源传输信道状态信息，即基站向终端传输信道状态信息，使得终端选择适合的上行波束，具体的方法与本申请实施例提供的方法类似，区别仅在于将上行资源变为下行资源，本领域技术人员均能根据本申请所提供的信道测量方法，在下行资源上实现信道状态信息的传输，本实施例中不再赘述。
另外，对于同一个接收端，在相同的符号上使用相同的接收波束进行接收信号，这在多个发射接收点(Transmission and Reception Point，TRP)联合传输的时候并不能很好地根据不同TRP对应的信道特征来灵活地接收信道或者信号。为此本申请实施例还提供一种空间接收参数的确定方法。
本申请实施例中的一种空间接收参数的确定方法包括：确定A类信道和/或信号关联的组信息；
根据确定的A类信道和/或信号关联的组信息，确定如下至少之一：A类信道和/或信号中的至少一类信道和/或信号的空间接收参数，A类信道和/或信号的传输方式；
其中A类信道和/或信号占有的时域资源之间的交集非空，A为大于或等于2的正整数。
在本申请实施例中，确定A类信道和/或信号关联组信息；根据A类信道和/或信号关联的组信息，确定A类信道和/或信号中的至少一类信道和/或信号的空间接收参数。
根据确定的A类信道和/或信号关联的组信息，确定A类信道和/或信号中的至少一类信道和/或信号的空间接收参数，包括如下至少之一：
A类信道和/或信号关联的组信息相同时，A类信道和/或信号关于空间接收参数满足准共址关系；
A类信道和/或信号关联的组信息相同时，A类信道和/或信号在交集部分关于空间接收参数满足准共址关系；
A类信道和/或信号关联的组信息不同时，A类信道和/或信号分别关联一个空间接收参数；
A类信道和/或信号关联的组信息不同时，A类信道和/或信号在交集部分分别关联一个空间接收参数。
下面以A＝2为例进行说明，下述的描述中A类信道和/或信号关联的组信息相同时满足如下关系，如果A类信道和/或关联的组信息不同时，不需要满足如下关系。
情况1:当调度PDSCH的下行控制信息(Downlink Control Information，DCI)和物理下行共享信道(Physical Downlink shared channel，PUSCH)之间的间距小于预定阀值，PDSCH和控制资源集合(Control resource set，CORESET)之间时域交集非空(CORESET是配置为用于传输下行控制信息的时频资源块)，PDSCH和CORESET的'QCL-TypeD'(即空间接收参数)不同，PDSCH和CORESET关联相同的组信息时，优先接收CORESET中的物理下行控制信道(Physical Downlink control channel，PUCCH)。此时PDSCH的'QCL-TypeD'是距离PDSCH最近的时间单元中关联至少一个要检测的搜索空间具有最低CORESETID且在PDSCH所在的载波组件(Carrier Component，CC)中的CORESET的'QCL-TypeD'。
情况2：如果UE被配置CSI-RS资源和一个搜索空间集合(a search space set)关联的CORESET有至少一个相同的正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号，且CSI-RS和CORESET有相同的组ID，如果'QCL-TypeD'被配置了，终端假设CSI-RS和这些搜索空间集合关联的CORESET包含的所有PDCCH的解调参考信号(Demodulation Reference Sgnal，DMRS)关于’QCL-TypeD’满足准共址关系，这个也可以应用于CSI-RS和CORESET在不同带内跃迁组载波(intra-band component carriers)的情况。
情况3：如果终端配置的CSI-RS资源和SS/PBCH资源块占有的OFDM时域符号交集非空，并且CSI-RS资源和SS/PBCH资源块有相同的组ID，如果'QCL-TypeD'有被应用，那么CSI-RS和SS/PBCH资源块是关于'QCL-TypeD'满足准共址关系。
情况4：如果终端接收的PDSCH的DMRS和SS/PBCH资源块占有的OFDM符号交集非空，PDSCH的DMRS和SS/PBCH资源块有相同的组ID，且如果'QCL-TypeD'被配置了，那么DM-RS和SS/PBCH资源块是关于'QCL-TypeD'满足准共址关系。
情况5：如果终端被配置成单载波或载波聚合(Carrier Aggregation，CA)模式，属于多个CORESET的PDCCH的检测机会(occasion)之间的交集非空，且这些CORESET具有相同的组索引，则终端检测其中一个CORESET和与这个CORESET之间满足QCL-TypeD的CORESET中的PDCCH。
上述组ID为如下至少之一：下行控制信道元素组索引，传输配置指示(Transmission Configuration Indicator TCI)状态组索引，天线组索引，信道和/或信号组索引，信道和/或信号的参数值组索引。其中下行控制信道元素包括如下之一：CORESET，搜索空间集合，搜索空间，候选PDCCH。比如不同的组对应不同的TRP。
上述A类信道和/或信号之间的交集非空且具有相同的组索引时，A类信道和/或信号之间关于QCL-typeD(即空间接收参数)满足准共址关系，本实施例也不排除，A类信道和/或信号之间的交集非空且具有相同的组索引时，A类信道和/或信号之间关于QCL-typeD(即空间接收参数)的准共址参考信号构成的集合中，包括的参考信号的个数小于第三预定门限，或者A类信道和/或信号之间关于QCL-typeD(即空间接收参数)的准共址参考信号构成的集合中，包括的不满足准共址关系的参考信号的个数小于第三预定门限，比如对于一个TRP终端可以打出多于一个的接收波束。
A类信道和/或信号之间的交集非空且具有不同的组索引，A类信道和/或信号之间关于QCL-typeD(即空间接收参数)不需要满足准共址关系，A类信道和/或信号之间关于QCL-typeD(即空间接收参数)的准共址参考信号构成的集合中，包括的不满足准共址关系的参考信号的个数小于第四预定门限，其中第四门限大于第三预定门限，比如终端对于每个TRP终端可以打出预定个数个接收波束，终端对于两个TRP终端可以打出的接收波束的个数大于终端对于一个TRP终端可以打出的接收波束的个数。
在一实施例中，一个信道和/或信号关联一个下行控制信道元素组，包括如下至少之一：
调度信道和/或信号的物理层控制信道在下行控制信道元素组中传输；
调度信道和/或信号的高层信令包括在下行控制信道元素组中传输的控制信道调度的下行数据信道中；比如调度周期或者半持续信道和/或信号的RRC/MAC-CE命令包括在一个CORESET组1的PDCCH中，则称这些周期或者半持续信道和/或信号关联的CORESET组为CORESET组1。
在一实施例中，在上述情况1～5中，当A类信道和/或信号关联的组信息不同时，他们之间不需要关于空间接收参数满足准共址关系。
在一实施例中，A类信道和/或信号关联的组信息不同时，包括如下特征至少之一：
A类信道和/或信号关联的组信息不同且A类信道和/或信号关于空间接收参数的准共址参考信号构成的集合中不满足准共址关系的参考信号的个数大于G 时，根据组信息的优先级，传输A类信道和/或信号中的B类信道和/或信号，其中B值为小于A值的正整数；

其中G，H是大于或者等于1的正整数，和/或根据以下信息至少之一获取G值：下行控制信道元素组，TCI状态组，天线组，信道和/或信号组，和/或H小于G。
比如相同组的信道和/或信号由同一个TRP发送，不同组的信道和/或信号由不同TRP发送。
比如CORESET组有两个，分别对应一个TRP，两类信道和/或信号关联的组信息不同且两类信道和/或信号关于空间接收参数的准共址参考信号构成的集合中不满足准共址关系的参考信号的个数小于或者等于2时，传输两类信道和/或信号；
比如CORESET组有两个，分别对应一个TRP，两类信道和/或信号关联的组信息相同且两类信道和/或信号关于空间接收参数的准共址参考信号构成的集合中不满足准共址关系的参考信号的个数大于1时，传输两类信道和/或信号中的一类信道和/或信号；
需要说明的是，本申请说明书中的所有部分的传输包括发送和/或接收，在信道和/或信号的发送端就是发送，在信道和/或信号的接收端就是接收。
在本申请实施例中，确定A类信道和/或信号关联的组信息；
根据A类信道和/或信号关联的组信息，确定A类信道和/或信号的传输方式包括如下至少之一：
A类信道和/或信号关联的组信息不同且A类信道和/或信号关于空间接收参数不满足准共址关系时，根据组信息的优先级，传输A类信道和/或信号中的B类信道和/或信号，其中B值为小于A值的正整数；比如组信息索引最小的信道和/或信号的优先级最高。比如不同的组信息对应不同的TRP。
在本申请实施例中，A类信道和/或信号占有的时域资源之间的交集非空时，传输A类信道和/或信号中的B类信道和/或信号，根据A类信道和/或信号关于空间接收参数的准共址参考信号构成的参考信号集合中，包括的参考信号的个数和第一预定值的关系，确定B值。比如A类信道和/或信号关于空间接收参数的准共址参考信号构成的参考信号集合中，包括的参考信号的个数大于第一预定值，B值小于A值或者根据A类信道和/或信号关联的组信息之间的关系确定B值，否则B值等于A值。
