为了便于叙述，在本申请中，对于参考信号的测量，也称为对于导频的测量，简称导频测量；对于参考信号的测量上报，也称为对于导频的测量上报，简称为导频测量上报或者测量上报。对于导频测量的上报设置，简称为上报设置。
在上述无线通信系统中，对于导频测量上报，从时域的角度，可以分为非周期性测量上报，周期性测量上报，以及半静态测量上报。
非周期性测量上报是是动态触发的；通过高层，例如无线资源控制(radio resource control,RRC)层，配置测量上报参数，通过MAC-CE(media access control control element，媒体接入控制控制元素)或DCI(downlink control information，下行控制信息)动态的激活上报测量上报参数；例如在用户的移动过程中，当基站检测到当前链路信号质量较差时，动态触发用户进行邻区的测量及上报。
周期性测量上报是指以特定的时间间隔周期性的上报测量上报参数；通过高层(例如RRC层)配置测量上报参数、及上报周期；例如用户接入基站后，会接收基站发送的测量配置，其中包括了需要周期性上报的测量上报参数，终端会根据上报周期周期性得上报上述测量上报参数的值。
半静态测量上报是指测量上报是可以动态激活和去激活的；通过高层(例如RRC层)配置测量上报参数、及上报周期，通过MAC-CE或DCI动态的激活或去激活上述测量上报参数的上报；当激活时，该测量上报类似于周期性测量上报；当去激活时，不需要上述测量上报参数的上报。
在上述无线通信系统中，对于导频测量上报，从频域的角度，可以分为全带宽(wideband)测量上报，部分带宽(partial band)测量上报，以及子带(subband)测量上报。
全带宽测量上报是指针对服务基站的整个工作频段的测量上报；例如当前工作频段为10MHz，用户需要对全带宽的导频进行测量及合并，上报针对全带宽的测量上报参数的值。
部分带宽测量上报是指针对服务基站的部分工作频段的测量上报；例如服务基站可支持不同的业务类型服务，不同的业务类型占用整个工作频段的部分带宽，根据用户的当前业务类型，只需要上报针对部分带宽的测量上报参数的值。
子带测量上报是指将服务基站的整个工作频段划分为多个子带，由基站或用户侧选取所上报的针对一个或多个子带的测量上报参数的值。
在上述无线通信系统中使用波束进行传输，可以实现更高的天线阵列增益。在使用波束进行通信的过程中，需要对波束进行管理，例如如何选择通信质量较佳的波束，如何建立波束的通信链路，如何优化所选择波束来提供通信信道容量等。为了实现有效的波束管理，可以通过对导频的测量实现波束管理。例如：基站通过不同的波束发送导频(可以简单地理解为在不同方向上发送导频)，终端测量不同波束上的导频以获得各个波束上导频的测量结果，并将测量结果反馈给基站，以便进行波束管理。上述利用不同波束发送的导频可以是CSI-RS。
导频的测量上报既可用于波束管理也可用于链路自适应调度。作为一种可选的设计，终端上报的测量上报参数可以包括以下一种或多种：
1)接收波束指示：用于指示用户侧或基站侧接收波束索引或编号。接收波束指示可以指示一个接收波束，也可以指示多个接收波束。接收波束指示可以使用逻辑标识表达。其中，该逻辑标识可以标识单个波束，或者可以标识一组波束。例如该逻辑标识可以是波束的标识。当逻辑标识用于标识一组波束时，该逻辑标识可以认为是一种组标识。例如一个接收波束集的标识，或者一接收天线组的标识。通常，组标识可以是BPL的标识，或者QCL的标识。通常，归为一组的标识具有某种或者某些相同或者相似的通信特征或者空间特性。接收波束指示也可以称为接收波束索引指示，接收波束索引指示是一种波束索引指示。
2)发送波束指示：用于指示用户侧或基站侧发送波束索引或编号。发送波束指示可以指示一个发送波束，也可以指示多个发送波束。与接收波束指示类似的，可以使用逻辑标识表达，相关内容请参见接收波束指示的相关内容。作为另一种可选的方式，发送波束指示还可以使用参考信号的资源标识，或者天线端口号来标识。例如：使用CSI-RS的资源标识或者天线端口号来标识发送波束，或者使用CSI-RS的资源标识和天线端口号的组合来标识发送波束。发送波束指示也可以称为发送波束索引指示，发送波束索引指示是一种波束索引指示。
3)波束质量(beam quality)：用于体现波束的质量。波束质量可以使用参考信号的接收功率来表示，例如层一CSI-RS接收功率(L1CSI-RS reference signal received power,L1CSI-RS RSRP),即在终端的天线连接处测得的CSI-RS的线性平均功率，单位为瓦特[W]。
4)空分特性(spatial parameters)：用于指示基站与用户之传输信道的空间特性。例如：平均到达角度(mean zenith angle of arrival)或者平均到达角(mean angle of arrival)可以理解为是一种空分特性。
5)资源选取指示(resource selection indicator，RSI)，用于指示当前测量上报对应的导频的资源集合，或者导频资源，或者导频端口，或者导频资源的波束信息。例如，资源选取指示可以参考LTE中的信道状态信息参考信号资源指示(channel state information reference singal resource indicator，CRI)。
6)秩指示(rank indicator，RI)，用于指示当前用户可采用的传输层数。
7)预编码矩阵指示(precoding matrix indicator，PMI)，用于指示当前用户可采用的预编码信息。例如，对于下行传输，当基站只有一个天线面板(antenna panel)时，PMI可以分为2个部分，一部分为长期的信道质量的预编码信息或波束选取(可用W1表示)，另一部分为短期/瞬时的信道质量的预编码信息(可用W2表示)；当基站采用多个天线面板时，PMI可以分为3个部分，一部分为W1，一部分为W2，另一部分为多个天线面板之间的带宽或者子带的相位信息(co-phasing factor)(可用W3表示)。其中，W3可以独立上报，也可以嵌入到W1或W2内联合上报。W1有时也称为第一PMI，W2有时也称为第二PMI。
8)信道质量(channel quality，CQ)，用于指示当前用户的信道质量。例如可以参考LTE中的信道质量指示(channel quality indicator,CQI。信道质量可量化为调制编码方案(modulaiton and coding scheme，MCS)的等级指示。
9)基于线性合并码本的预编码(反馈)，用于指示最终的预编码信息。例如，对于两级码本反馈，W1用于反馈选取的多个波束指示，W2用于指示W1所选取的多个波束的一组或多组加权向量，通过上述2个部分可以联合指示最终的预编码信息。
10)协方差矩阵(反馈)，用于指示长期的、宽带的信道协方差矩阵。
11)混合CSI(反馈)，用于指示基于线性合并码本的预编码与基于波束成形的CSI-RS(beamformed CSI-RS)测量的联合反馈。
12)干扰量(反馈)，用于指示小区内配对用户的干扰量，或者小区间干扰量，或者波束间干扰量。
对于上述参考信号(导频)的测量，可以由网络侧为终端下发测量配置(measurement setting)。例如，测量配置可以包括一个或多个链接(link)，该链接对应一个上报设置(reporting setting)和一个资源设置(resource setting)；每一个资源设置(resource setting)包括一个或多个资源集合(resource sets)，每个资源集合(resource sets)进一步包括一个或多个导频(例如：CSI-RS)资源，每个导频资源对应一个资源索引，用于唯一标识该导频资源。该测量配置可以用于上述波束测量，也可以用于上述导频测量。根据不同的测量需求，终端所需要上报的测量上报参数不同。例如，对于P2波束扫描，需要上报发送波束指示，对于P3波束扫描，需要上报接收波束指示。因此，终端具体上报的测量上报参 数会根据网络应用场景或者波束扫描的模式不同而发生变化。通过上述测量配置，可以运用于波束管理，以及链路自适应调度。
在本申请中，索引可以理解为一种标识，索引也可以称为编号。
作为一种简化的理解，资源设置可以理解为指示参考信号(导频)在哪些资源(例如频域资源，时域资源，或者空间资源)上传输，上报设置可以理解为指示要上报的测量上报参数，链接可以理解为测量资源设置和测量报告设置的关联关系。通过上述测量配置，终端可以知道测量特定资源上传输的参考信号需要获得哪些测量上报参数，以及如何获得这些测量上报参数的值，并且以何种方式上报。
以下给出如何配置终端需要上报哪些测量上报参数的方法示意。图4中的基站和终端可以是图2和图3中的基站和终端，图4的网络场景可以如图1所示。
如图4的S101和S102所示：
S101：终端向基站发送上报能力。
上述发送功能可以由终端的收发机实现。
换而言之，基站从终端接收上报能力。上述接收功能可以由基站的收发机实现。
上报能力可以理解为测量能力，测量上报能力。作为一种示例，上报能力包括：终端可支持的最大工作带宽、终端的接收天线个数等。
可选的，终端可以通过RRC信令或者物理层信令向基站发送上述测量能力信息。
S102：基站向终端发送包括一个或多个上报设置(reporting setting)的测量配置。
上述发送功能可以由基站的收发机实现。
换而言之，在S102部分，终端从基站接收上述测量配置。上述接收功能可以由终端的收发机实现。
上述上报设置包含在测量配置(measurement setting)消息内，每一个上报设置(reporting setting)包括以下信息中的一个或多个：上报设置的索引，用于唯一标识一个上报设置；导频测量上报的时域特性(例如：周期的，非周期的，半静态的)；导频测量及上报的频域粒度(例如：终端决策的子带反馈，基站配置的子带反馈，全带宽反馈，部分带宽反馈)；测量上报的内容(例如：PMI，RI，CQI，CRI)；波束扫描方法的指示信息；可选的，测量配置还可以包括测量限制，码本配置，如果为周期性上报，每一个上报设置(reporting setting)还包括上报量所对应的上报周期及上报时间偏移量。
在本申请中，可以认为测量上报参数是被包括在测量配置中的，或者可以认为测量上报参数是被包括在上报设置中的。
其中，测量限制是针对上报设置而配置的，用于通知用户当前的测量行为，例如，是基于单次采样点的测量结果还是基于一段时间内的测量平均结果；码本配置用于指示PMI上报应采用的码本集合索引。时域特性是针对上报设置而配置的，适用于上报设置所包含的所有测量上报参数；频域特性是针对测量上报参数而配置的，例如上述的测量上报参数3)、4)、7)、8)、9)、10)、11)、12)可配置频域特性。
可选的，测量配置可以通过高层信令发送至终端。例如，该高层信令可以是无线资源控制(radio resource control，RRC)信令。
作为一种可选的设计，终端接收到测量配置后，可以根据测量配置进行测量。如图4的S103和S104所示：
S103：基站发送参考信号(导频)；
S103的发送功能可以由基站的收发机实现。
S104：终端对上述参考信号进行测量，获取多个测量上报参数的值。
S104中测量和获取功能可以由终端的处理器和收发机实现。
作为另一种可选的设计，终端接收到测量配置后，并不立即根据测量配置进行测量上报，还需要等待基站发送的上报激活指示来确定是否开启测量配置中测量上报参数的上报。
例如：在将测量配置发送至终端后，基站可以根据参考信号的功能，或者当前的传输模式，或者，应用场景，或者波束扫描模式向终端发送上报激活指示，用于激活终端需要上报的测量上报参数，即激活终端对于该测量上报参数的上报行为。如图4中S105所示：
S105：基站向终端发送上报激活指示。
S105的发送功能可以由基站的收发机实现。
换而言之，终端从基站接收上报激活指示。该接收功能可以由终端的收发机实现。
其中，上述上报激活指示可以理解为对于是否要对测量上报参数进行上报的开关。例如测量配置中指示了需要上报测量上报参数1，测量上报参数2，测量上报参数3，上述上报激活指示可以指示激活测量上报参数1和2，则终端会根据测量配置对测量上报参数1和2进行上报，而不进行测量上报参数3的上报。
可选的，基站可以通过RRC信令，MAC-CE，或者DCI向终端发送上报激活指示。
可以理解，S102部分中的测量配置或者上报设置也可以认为是一种上报激活指示，此时S105部分无需执行。
作为一种可选的实施方式，当参考信号的功能，或者当前的传输模式，或者，应用场景，或者波束扫描模式发生变化时，基站可以再次执行S103，以改变终端的测量上报参数。例如，可以关闭一些激活的测量上报参数，或者打开一些新的测量上报参数。其中，关闭可以理解为去激活，打开可以理解为激活。
之后，终端可以根据上述上报设置上报测量上报参数。例如：
S106：终端向基站发送测量上报参数的值。
S106中的发送功能可以由终端的收发机实现。
换而言之，基站从终端接收测量上报参数的值。该接收功能可以由基站的收发机实现。
终端可以根据上报设置向基站发送测量上报参数的值。
作为一种可选的设计，终端可以根据测量上报参数以及其对应的上报周期或者上报时间偏移量来上报测量上报参数。例如：终端根据测量配置可知在第K个子帧需要上报CQ，PMI，接收波束指示，波束质量，则终端可以在第K个子帧上报上述CQ，PMI，接收波束指示和波束质量。
作为一种可选的设计，可以对上报测量上报参数的方式进行约定。例如，可以约定测量上报类型，简称上报类型。终端在上报测量上报参数时，需要按照上报类型中所规定的测量上报参数进行上报。例如，终端根据测量配置可知在第K个子帧需要上报CQ，PMI，接收波束指示，波束质量；如果存在测量上报类型X，测量上报类型X规定终端可以在一 个子帧内同时上报CQ，PMI和波束质量，且不存在一种测量上报类型规定终端可以在一个子帧内同时上报CQ，PMI，波束质量和接收波束指示，则终端将按照测量上报类型X在第K个子帧上报CQ，PMI和波束质量，而不会上报接收波束指示。
上报类型的一种可选的设计如下：
上报类型1：波束索引指示(波束指示)；该上报类型用于告知基站，对于终端哪些接收/发送波束是最好的，或者符合质量要求的，或者是可用的。波束索引指示可指示一个或多个(例如N个)接收/发送波束。数目N可以由通信标准规定或者由基站通过RRC,MAC-CE,DCI等信令通知，或终端自主选择的一个或多个(例如N个)接收/发送波束。
上报类型2：信道质量；该上报类型用于告知基站信道或者波束质量。作为一种可选的实现方式：终端选取最好的一个波束对(即该终端的接收波束和它所收到的基站的一个最好的发送波束)，上报波束对的信道质量；作为另一种可选的实现方式：基站配置的一个或多个(例如N个)波束的导频资源，终端侧按照基站配置依照基站配置的顺序上报一个或多个(例如N个)波束的信道质量，。其中，信道质量可以是层一参考信号接收功率(layer 1 reference signal received power,L1-RSRP)，或者是层一参考信号接收质量(layer1 reference signal received quality，L1-RSRQ),或者CQI。

波束索引指示可以是接收波束索引指示，也可以是发送波束索引指示，也可以是发送波束索引指示和接收波束索引指示。
波束索引指示可以用资源设置ID(identity)，也可以是资源集合ID，也可以是参考与信号资源ID，也可以是端口号ID，还可以是资源设置ID、资源集合ID、参考与信号资源ID、端口号ID的各种组合，也可以是同步信号块时间索引(SS block time index,SS means Synchronization signal)来表示。
在本申请中，ID可以表示标识的意思。
接收波束索引指示可以是终端接收波束集合，也可以是终端接收波束，也可以是终端接收天线组，也可以是终端接收天线。也可以是接收波束集合与接收天线组的各种组合。

根据测量配置，可能会出现终端需要同时向基站上报多个测量上报参数的情况。如果用于上报测量上报参数的资源不足，或者多个测量上报参数之间存在信息冗余的情况，则可以理解为测量上报发生了冲突。
当测量上报发生冲突时，终端可以在多个测量上报参数中按照上报规则选择部分的测量上报参数进行上报，即终端向基站发送多个测量上报参数中部分测量上报参数的值，上述部分测量上报参数满足上报规则。其中部分测量上报参数可以是一个也可以是多个。

上述上报规则4-6可以认为是一种频域的上报规则。
上报规则7：第一类测量上报参数优先级高于第二类测量上报参数，即第一类测量上报参数优先于第二类测量上报参数；例如，当终端根据测量配置可知在第K个子帧需要接收波束和RI，则终端优先上报接收波束索引标识。其中，上报测量参数1)、2)、5)为第一类测量上报参数，上报测量参数3)、6)、7)、8)为第二类测量上报参数。
上报规则8：第二类测量上报参数优先级高于第三类测量上报参数，即第二类测量上报参数优先于第三类测量上报参数。例如上报测量参数3)、6)、7)、8)为第二类测量上报参数，上报测量参数4)，9)，11)，12)为第三类测量上报参数。

基于以上多种上报规则，在多种规则同时满足，需要约定多种规则的处理方式：
可选的处理方法一：首先根据用户的上报时域特性处理；如果上报时域特性优先级相同时，根据上报内容处理；如果上报内容优先级相同时，根据上报类型处理；
可选的处理方法二：将各种上报规则进行加权处理，合并后值大的上报优先级高于值小的测量上报参数；例如：优先级值＝a*时域特性上报规则+b*频域特性上报规则+c*上报内容上报规则+d*上报类型上报规则+e*配置信息上报规则；其中，a,b,c,d,e>＝0，具体取值可由基站配置，也可是协议事先约定；其中，不同的时域特性、不同的频域特性、不同的上报内容、不同的上报类型、不同的配置信息可取相同的值，也可取不同的值，例如，周期性和半静态时域特性为1，非周期性时域特性为2；具体的，假设为用户配置了两个测量上报设置，周期性测量上报设置1包含上报量接收波束索引指识和全带宽信道质量；非周期性测量上报设置2包含全带宽PMI和RI；当这两个上报设置的测量上报参数发生在同一时刻，计算其所对应的优先级值：上报设置1优级级值＝a*周期性权值+b*全带宽权 值+c*第一类上报内容权值+d*上报类型3权值；上报设置2优级级值＝a*非周期性权值+b*全带宽权值+c*第二类上报内容权值+d*上报类型7权值；如果上报设置1优级级值大于上报设置2优级级值，则终端只上报上报设置1所对应的测量上报参数。如果上报设置2优级级值大于上报设置1优级级值，则终端只上报上报设置2所对应的测量上报参数。
在上述方法中，终端可以按需反馈各个空间资源上的导频的测量结果给基站，便于基站自适应各个空间资源的数据传输调度和空间资源管理，从而提高无线通信系统的性能。另外该方法在实现上简单、优雅(elegant)，可以兼容CSI测量上报。
