然而，高频段通信也面临着链路衰减的挑战，具体而言，包括传播路径损失大、空气(尤其是氧气)吸收更大、雨衰影响较重等。面对这些挑战，高频段通信系统可以利用高频段波长较短和易于天线集成等特点，通过多天线阵列和波束赋形方案来获取高天线增益和对抗信号传输损耗，进而以确保链路余量和提升通信鲁棒性。
在天线权重(也称为，预编码、波束)训练过程中，高频段发送端发送训练导频，接收端接收信道并执行信道估计。然后，高频段接收端需要 向训练发送端反馈信道状态信息，便于实现收发端从可选的收发端天线权重对中，找到可以用于多路数据传输所需要的多组收发端天线权重对，提升整体的频谱效率。

本实施例提供了一种信道相关信息的反馈方法，侧重于在触发条件下的用户主动反馈信道质量信息(相当于上述实施例中的参考信号相关的信息)应用于第一通信节点(即UE用户端)，该方法包括：根据波束相关参数集合中的K个元素的触发第一类门限生成第一类信令；向第一通信节点所述发送所述第一类信令；其中，K是大于或等于1的整数。该流程，也可以被称为波束恢复，或者用户主动的波束上报。
其中，所述的波束相关参数集合，用于信道质量判决，波束相关参数集合包括以下至少之一：N个第一类波束链路的质量；N个第一类波束链路的质量与K个第二类的波束链路质量和的差值或者比值；N个第一类波束链路与K个第二类的波束链路的时频信道响应的相关性、或者频域信道响应的相关性，空域相关性；N个第一类波束链路的方位角与K个第二类的波束链路的方位角的差值或者比值；K个第二类波束链路质量；全部第二类波束链路质量；距离上次上行控制信道或数据信道成功接收的时间累计；未成功接收的累计次数；波束分组的调整信息；所述波束相关参数集 合所包括的各个参数的加权值或者加权相关值。在一实施例中，所述信道质量判决，可以是要求波束相关参数集合中的元素连续C次触发判决门限，其中C是基站配置量，或者预定义量。其中，C为大于或等于1的整数

其中N，S，S1是大于或等于1的整数，并且S1小于或等于S。
在一实施例中，所述波束链路对应于以下之一：发送波束、接收波束、收发波束对、波束组、接收波束组、发送波束组、接收模式、天线组合，控制信道，下行参考信号，上行参考信号。

此外，第一类信令，可以称为波束恢复请求信令，包括参考信号索引，可选波束序号，或者相关联的信道状态信息(例如RSRP)。第一类信令，可以通过如下的信道传输之一或组合进行传输：物理上行控制信道(PUCCH)，物理随机接入信道(PRACH)，其中，物理随机接入信道，为基于竞争的物理随机接入信道或者免竞争的专属物理随机接入信道。
图10是本发明实施例提供的基于触发条件的信道质量反馈的流程示意图。基站配置周期的CSI-RS，用于检测波束失败。若所述的CSI-RS所关联下的BLER性能大于或者大于等于判决门限后，UE端判定波束失败事件 成立(beam failure detection)。此外，基站配置同步块(SS block，SSB)和周期的CSI-RS资源，构成第一类波束链路质量。如果所述的第一类波束链路质量中一个CSI-RS资源所关联的信道质量(例如BLER或者RSRP)触发门限后，UE端宣布发现了新的备选波束(new candidate beam)。
当全部的第二类波束链路质量(CSI-RS)触发门限，并且存在一个第一类波束链路质量(例如CSI-RS，或者SS block)触发门限，用户可以启动第一类信令发送流程，即在对应上行资源上，可以发送第一类信令，例如波束恢复请求信令。
在一实施例中，侧重于第一类信令发送的约束条件，考虑在触发条件满足，或者波束失败(beam failure)的情况下，用户会从备选的波束集合(即已配置的可选波束，第一类波束链路)中选择新的可用波束。但是，需要对于用户端的行为进行限制，可以确保UE在有效的时间约束和次数约束下，快速执行波束恢复流程，进而确保波束恢复性能，防止波束恢复时间过长，UE长时间等待有效波束。
对于第一类信令，包括如下配置信息之一或组合：第一类信令次数门限，累计时间门限。
在一实施例中，上述配置约束条件如下：若配置信息为第一类信令次数门限时，第一类信令次数超过所述的第一类信令次数门限，第二通信节点停止发送第一类信令；或者，若配置信息为累计时间门限时，所关联的计时单元超过所述的累计时间门限，第二通信节点停止发送第一类信令；或者，若配置信息为累计时间门限和第一类信令次数门限时，所关联的计时单元超过所述的累计时间门限，和/或第一类信令次数超过所述的第一类信令次数门限，第二通信节点停止发送第一类信令。
此外，考虑第一类信令无法有效发送，(即发生波束恢复失败后)，还包括至少如下之一：在第二通信节点向第一通信节点发送的第一类信令的 次数，或者累计时间，或者组合，超过门限后，第二通信节点向高层告知第A类信息；在第二通信节点向第一通信节点发送的第一类信令的次数，或者累计时间，或者组合，超过门限后的Y个时间单位之内，第二通信节点向高层告知第A类信息；其中，Y为大于或等于0的整数。所述的第A类信息，表示波束恢复失败，和/或表示无线链路失效的触发条件。
需要说明，关于累计时间的计算起点约束。对于第一类信令发送的约束而言，累计时间的起始点可以为如下之一：1)检测到所关联的链路或者波束失效时刻，或者检测到所关联的链路或者波束失效时刻所关联的时间窗的标记时刻；2)波束失效检测结果触发门限时刻，或者波束失效检测结果触发门限时刻所关联的时间窗的标记时刻3)第一次发送第一类信令时刻，或者第一次发送第一类信令时刻所关联的时间窗的标记时刻；4)第二通信节点配置用于承载第一类信令的上行资源的时刻，或者第二通信节点配置用于承载第一类信令的上行资源的时刻所关联的时间窗的标记时刻；5)第一类信令承载的参考信号索引的发送时刻，或者第一类信令承载的参考信号索引的发送时刻所关联的时间窗的标记时刻；6)第一次使用PUCCH发送第一类信令的时刻，或者第一次使用PUCCH发送第一类信令所关联的时间窗的标记时刻；7)第一次使用PRACH发送第一类信令的时刻，或者第一次使用PRACH发送第一类信令所关联的时间窗的标记时刻；其中，所述的时间窗标记时刻是指，所述的时间窗的开始时刻、或者中间时刻、或者结束时刻。
在一实施例中，第一类信令的发送次数包括至少如下之一：1)所述的第一类信令次数，指使用PUCCH资源的发送第一类信令次数；2)所述的第一类信令次数，指使用PRACH资源的发送第一类信令次数；3)所述的第一类信令次数，指使用PRACH发送第一类信令次数和PUCCH资源的发送第一类信令次数的总和。
在一实施例中，侧重于第一类信令关联的PRACH资源的配置方法，由于第一类信令涉及使用PRACH，而在初始接入阶段已经有PRACH资源已经被预先配置，所以对于UE而言，应该限制用于发送第一类信令的PRACH资源配置。另外，因为在初始接入阶段PRACH仅会和SS block关联，但是对于第一类信令而言，可以与CSI-RS，SS block或者CSI-RS和SS block关联。因此，对于基站配置CSI-RS和SS block时，需要满足一定的UE端的假设，以便于UE支持相关的测量和第一类信令的上报。
对于PRACH资源分配限制，支持如下至少之一：若N个所述的PRACH所关联的下行参考信号满足信道特性假设时，则N个PRACH资源分配在相同的时域单元，或者支持频分FDM；第一通信节点，不希望所关联的下行参考信号满足信道特性假设的PRACH分配在不同的时域单元；其中，所述的时域单元，包括时隙、子帧、符号或者符号集合。在一实施例中，下行参考信号包括如下之一或者组合：CSI-RS，SS block。
PRACH资源有如下特征，包括如下至少之一：第一类信令的PRACH所关联的SS block的对应的初始接入的PRACH的时域位置，确定第一类信令的PRACH资源的时域位置；其中，所述的初始接入的PRACH的时域位置，是由第一通信节点向第二通信节点发送的初始接入的PRACH的配置信令实现；而，时域位置，即时域偏置信息。
第一类信令的PRACH所关联的SS block的对应的初始接入的PRACH资源，确定第一类信令的PRACH资源；第一类信令的PRACH所关联的CSI-RS的满足相同信道特征假设的SS block的对应的初始接入的PRACH的时域位置，确定第一类信令的PRACH资源的时域位置；第一类信令的PRACH所关联的CSI-RS的满足相同信道特征假设的SS block的对应的初始接入的PRACH资源，确定第一类信令的PRACH资源。
第一通信节点，不希望第一类信令的PRACH所关联的SS block的对 应的初始接入的PRACH的时域偏置，与第一类信令的PRACH资源的时域偏置不同；或者，第一通信节点，不希望第一类信令的PRACH所关联的SS block的对应的初始接入的PRACH的时频偏置，与第一类信令的PRACH资源的时频偏置不同。
时频偏置的基准，可以为每个SS block burst的首个SS block所在的OFDM符号(或者该OFDM符号的首个资源单元(resource element,RE))，或者首个SS block所在的部分带宽(bandwidth part,BWP)的首个资源单元(resource element,RE)。
第一通信节点，不希望第一类信令的PRACH所关联的CSI-RS的满足相同信道特征假设的SS block的对应的初始接入的PRACH的时域偏置，与第一类信令的PRACH资源的时域位置不同；或者，第一通信节点，不希望第一类信令的PRACH所关联的CSI-RS的满足相同信道特征假设的SS block的对应的初始接入的PRACH的时频偏置，与第一类信令的PRACH资源的时频位置不同；
在一实施例中，从预配置集合中选择部分集合，用于PRACH-beam recovery，其特征包括如下至少之一或组合：第二通信节点向第一通信节点发送第二类信令，从已配置或者预定义的PRACH资源中，指示其中V个PRACH资源，用于指示第一类信令所关联的PRACH资源的时域和/或频域位置；第二通信节点向第一通信节点发送第三类信令，从已配置或者预定义的CSI-RS资源和/或SS block中，指示其中T个CSI-RS资源和/或SS block，与第一类信令的PRACH资源关联；第一类信令所关联的PRACH，使用第一类信令的PRACH所关联的SS block的对应的初始接入的PRACH资源；或者，第一通信节的默认配置如下：第一类信令所关联的PRACH，使用第一类信令的PRACH所关联的SS block的对应的初始接入的PRACH资源；第一类信令所关联的PRACH，使用第一类信令的PRACH所关联的 CSI-RS的满足相同信道特征假设的SS block的对应的初始接入的PRACH资源；或者，第一通信节的默认配置如下：第一类信令所关联的PRACH，使用第一类信令的PRACH所关联的CSI-RS的满足相同信道特征假设的SS block的对应的初始接入的PRACH资源；其中，V和T是大于或等于1的整数。在一实施例中，从已有集合中选择特定集合，可以使用比特地图的方法。如果比特地图中比特位指为特定值(例如1)时，表示指示所述比特所关联的PRACH资源。
例如，基站已配置了16个周期的CSI-RS资源，而其中4个周期性的CSI-RS资源服务于当前的传输波束(即，第二类波束链路，serving beam)，而其余的12个周期的CSI-RS资源用于发现新波束(即，第一类波束链路，new candidate beam identification)。使用比特地图来选择已配置16个周期的CSI-RS资源的4个资源，即比特地图为16’b1111_0000_0000_0000，来表示第二类波束链路；另外，用16个周期的CSI-RS资源中的12资源，即比特地图为16’b0000_1111_1111_1111来选择已配置的另外的12个资源。
如果CSI-RS与SS block存在一对一对应关系，则比特地图为16’b0000_1111_1111_1111所对应的SS block所关联的PRACH资源，将会被配置作为第一类信令的专属上报资源。
如果每四个CSI-RS与一个SS block关联时，SS block所关联的PRACH时频资源将该四个CSI-RS关联，但是每个CSI-RS将会被配置或者按照预定义规则来使用4个不同的序列来进行区分。
此外，在支持配置多个QCL的CSI-RS和SS block的情况下，可以以SS block关联的PRACH为基准，然后以特定的频域步进量，来实现满足QCL关系的CSI-RS和SS block的配置。具体而言，第二通信节点向第一通信节点配置频域步进量，指示位于相同时域单元下的PRACH之间的频域间隔。多个QCL的CSI-RS使用相同的序列，但是通过不同的频域资源来 支持基站端对于CSI-RS资源的区分。
图11是本发明实施例提供的参考信号与PRACH资源关联方法的示意图。假定，系统配置了4个CSI-RS资源作为第二类波束链路(即new candidate beam identification)，而该四个CSI-RS资源共同与一个SS block满足信道特征假设(例如spatial QCL)。根据初始接入时SS block和PRACH的配置方法，CSI-RS资源与在相同时域资源，但是不同频域资源的PRACH进行一一映射。其中，第一个CSI-RS直接与SS block所关联的PRACH关联，而其余的CSI-RS依次与其他频域位置的PRACH关联。在一实施例中，如果对于SS block下，仅仅有一个CSI-RS被配置，这默认关联与之间满足关联关系的PRACH，即图中的PRACH-0。
此外，PUCCH和PRACH都可以用于承载第一类信令，可以共享一些相同配置，或者使用相同的配置或者模式，包括如下至少之一或组合：第二通信节点响应窗口持续时间；第二通信节点响应窗口与第一类信令之间的时间偏置；CORESET资源；搜索空间。
在一实施例中，第一通信节点(UE)基于准则反馈小于基站配置反馈限度的行为。
通过接收第二通信节点(即，基站端)发送的参考信号，第一通信节点(即，UE端)确定参考信号相关索引，参考信号接收功率，或者参考信号相关索引和参考信号接收功率，在一实施例中，将所述的参考信号相关索引，或者参考信号接收功率，或者参考信号相关索引和参考信号接收功率，报告给第二通信节点。需要说明，这里参考信号相关索引，是用于指示发送波束信息，因此该报告可以称为波束报告(beam reporting)。通过对于参考信号资源的指示，例如CSI-RS resource或者SS block，来实现对于发送波束或者发送端空间滤波器的指示上报(例如，指示有效波束索引)。
需要说明的，参考信号接收功率，是指RSRP(Reference Signal Received  Power)，为了便于讨论，本专利下文中使用RSRP来代替参考信号接收功率的描述。
在波束报告时，基站配置的参考信号相关索引的反馈数目N，而UE端反馈所述的被报告的参考信号相关索引的数目M，其中M小于或等于N，而M和N是大于或等于0的整数。在一实施例中，对于参考信号相关索引的反馈准则包括如下至少之一或组合：1)所述参考信号所关联的参考信号接收功率相对于最大的参考信号接收功率的差值，小于或者等于门限T-1；在一实施例中，T-1是第二通信节点配置，或者由差分的参考信号接收功率变化范围确定，或者在标准预定义；2)所述参考信号所关联的参考信号接收功率，相对于所述参考信号所在分组内最大参考信号接收功率的差值或者特定参考信号下的参考信号接收功率的差值，小于或者等于门限T-2；在一实施例中，T-2是第二通信节点配置，或者由差分的参考信号接收功率变化范围确定，或者在标准预定义；3)所述参考信号所关联的参考信号接收功率，相对于差分参考信号接收功率的参考功率的差值，小于或者等于门限T-3；在一实施例中，T-3是第二通信节点配置，或者由差分的参考信号接收功率变化范围确定，或者在标准预定义；4)所述参考信号所关联的参考信号接收功率，大于或者大于等于门限T-4；在一实施例中，T-4是第二通信节点配置，或者由差分的参考信号接收功率变化范围确定，或者在标准预定义。
例如，基站端配置了8个CSI-RS resource用于波束训练，而后配置相关资源用于UE端反馈beam reporting，其中允许反馈4个波束资源。经过对于8个CSI resource进行信道测量后，UE端获得了相对应的RSRP结果如表1所述。其中CRI，为CSI-RS resource indication。
表1
CRI-0 -79dBm
CRI-1 -60dBm
CRI-2 -96dBm
CRI-3 -74dBm
CRI-4 -95dBm
CRI-5 -130dBm
CRI-6 -110dBm
CRI-7 -86dBm
根据反馈4个波束资源的限制，{CRI-0,CRI-1,CRI-3,CRI-7}以及其相应的RSRP测量结果可以被反馈给基站端。比如：
情况1：若基站端配置了一个反馈的最小门限，即-85dB，则CRI-7将不能满足该门限限制，则用户端仅反馈如下信息:{[CRI-0,-79dBm],[CRI-1,-60dBm],[CRI-3,-74dBm]}。
情况2：UE端使用4-bit差分上报，每个bit的步进为-1dB，并且最大的接收信号功率为绝对值报告，而其他报告基于其的相对值。具体而言，我们有如下的差分表格如下表2所示。
表2
Figure PCTCN2018097523-appb-000001
当执行判定准则“所述参考信号所关联的参考信号接收功率相对于最大的参考信号接收功率的差值”，而判定门限基于差分表格的变化范围15个dB时。在UE端，由于最大的RSRP值为-60dBm,因此仅反馈-75dBm及其以上的波束，所以报告{[CRI-1,-60dBm],[CRI-3,-14dBm(i.e.,4’b1110)]}，而其他波束均不满足该准则。
情况3：UE端使用4-bit差分报告，每个bit的步进量为-1dB。并且，最大的接收信号功率为绝对值，而其他报告是基于与之接收功率最接近并且已经可上报的RSRP的差分报告。在UE端，最大的RSRP值为-60dBm，因此，首先差分反馈[CRI-3,-14dBm(i.e.,4’b1110)]，然后基于-74dBm再进行差分上报[CRI-0,-5dBm(i.e.,4’b0101)]，再然后，基于-79dBm再进行差分报告[CRI-7,-7dBm(i.e.,4’b0111)]。在该情况下，UE端报告信息如下：{{[CRI-1,-60dBm],[CRI-3,-14dBm(i.e.,4’b1110)],[CRI-0,-5dBm(i.e.,4’b0101)],[CRI-7,-7dBm(i.e.,4’b0111)]}。
需要说明，如果实际差分报告中参考RSRP测量值与报告值不符号时，应该以报告值中的参考RSRP作为基准进行差分报告。
在一实施例中，第一通信节点(UE)反馈波束报告分为两个不同部分，进行区分性的反馈。
对于波束报告而言，不同的内容下报告的紧迫性和优先级是不同的。因此，建议，将报告的内容才分成两级或者多级，其中每一个级别下有所对应的信息内容和调制编码模式，从而实现对于波束报告的灵活性的要求。
所述的波束报告内容，由第一信息和第二信息构成。其中，第一信息是由如下信息至少之一或组合构成：参考信号相关索引的数目；参考信号分组的数目；参考信号分组的组索引；分组中最大的参考信号的接收功率值；最大的参考信号接收功率值；差分报告中绝对的参考信号接收功率值；差分报告中绝对的参考信号接收功率值所关联的参考信号相关索引；第二通信节点指定的参考信号相关索引；第二通信节点指定的参考信号下的参考信号接收功率值。
此外，第二信息是有由参考信号相关索引和/或参考信号接收功率构成。在一实施例中，对于参考信号分组，也被称为波束分组(beam group)的准则包括如下至少之一或组合：参考信号分组内，不同参考信号不能同时接收；参考信号分组内部，不同参考信号能同时接收；参考信号分组内部， W1个不同参考信号能同时接收；参考信号分组之间，不同参考信号不能同时接收；参考信号分组之间，不同参考信号能同时接收；参考信号分组之间，W2个不同参考信号能同时接收；其中，W1和W2为大于或等于1的正整数。在一实施例中，W1和W2需要由UE告知给基站，或者基站根据UE的能力确定。
在一实施例中，在第二信息中，参考信号接收功率为相对接收功率；或者，在第二信息中，参考信号相关索引用比特地图指示；或者，第一信息的调制编码方式，与第二信息的调制编码方式不同。
在一实施例中，对于第一信息和第二信息，有如下配置之一：第一信息和第二信息均使用PUCCH资源反馈；第一信息和第二信息均使用PUSCH资源反馈；第一信息使用PUCCH资源反馈，而第二信息使用PUSCH反馈。
如果第一信息使用PUCCH资源反馈，而第二信息使用PUSCH反馈时，第二通信节点不能配置差分参考信号接收功率反馈；或者，第二通信节点能配置差分参考信号接收功率反馈；或者，第一通信节点，不希望第二通信节点配置差分参考信号接收功率反馈；或者，第一通信节点，希望第二通信节点配置绝对参考信号接收功率反馈。
图12是本发明实施例提供的在波束报告反馈方法的示意图一。根据表1所述描述的UE端的RSRP测量结果，UE将反馈内容分成两个部分，即第一报告部分及第二报告部分，其中，第一报告部分包括第一信息，第二报告部分中包括第二信息。其中，第一信息，承载最强的RSRP下的参考信号索引，和该索引下的RSRP；而，第二信息，承载其他的参考信号索引和该索引的RSRP。在一实施例中，第二信息采用差分RSRP报告，而第一信息使用绝对RSRP报告，并且报告结果作为第二报告中差分RSRP的参考值或者参考值之一。
图13是本发明实施例提供的在波束报告反馈方法的示意图二。根据表1所述的UE端的RSRP测量结果，并且根据分组准则“参考信号分组内部，不同参考信号能同时接收；参考信号分组之间，不同参考信号不能同时接收”。具体而言，根据该准则，UE将{CRI-1,CRI-3}分成第一个波束分组；而{CRI-0，CRI-7}作为第二波束分组，其中分组内不同参考信号可以同时接收，例如通过一个空间接收滤波器或者两个空间接收滤波器。
在一实施例中，UE将反馈内容分成两个部分，即第一报告部分及第二报告部分，其中，第一报告部分包括第一信息，第二报告部分中包括第二信息。其中，第一信息承载了第一波束分组(等价于参考信号分组)和第二波束分组下的最强的RSRP的CRI信息和其RSRP；而第二信息，承载所述分组各自的其他CRI信息以及其在以各自分组内绝对RSRP为参考的差分RSRP报告。
本一实施例中，波束分组下的差分参考信号接收信号功率反馈。
在参考信号分组，或者波束分组下，为了节省反馈开销，有必要引入差分的RSRP反馈方法。在一实施例中，该方法需要明确在分组，特别是多个分组下，参考RSRP的确定与分组之间的关系问题。具体而言，包括如下至少之一或组合：
a)参考信号分组内，X个参考信号下反馈差分参考信号接收功率；
b)从D个参考信号分组中，每个分组选择Y个参考信号，则所述的参考信号下反馈差分参考信号接收功率；
c)在参考信号分组内部和参考信号分组之间，J个参考信号下反馈差分参考信号接收功率；
其中X，Y，D，J为大于或等于1的正整数。
情况a)，在参考信号分组内，X个参考信号下反馈差分参考信号接收功率时，则所述的差分参考信号接收功率的参考功率可以是以下至少之一： 所述分组内，特定参考信号的参考信号接收功率；所述分组外，特定参考信号的参考信号接收功率；基站配置的差分参考信号接收功率报告的参考值；所述的X个参考信号内，特定参考信号的参考信号接收功率。
在一实施例中，特定参考信号相当于上述实施例中的指定参考信号。
情况b)，在从D个参考信号分组中，每个分组选择Y个参考信号，所述的参考信号下反馈差分参考信号接收功率时，所述的差分参考信号接收功率的参考功率可以是以下至少之一：所述D个参考信号分组内，特定参考信号的参考信号接收功率；所述D个参考信号分组外，特定参考信号的参考信号接收功率；基站配置的差分参考信号接收功率报告的参考值；从所述的D个参考信号分组的Y个参考信号内，特定参考信号的参考信号接收功率。
情况c)，在参考信号分组内部和参考信号分组之间，J个参考信号下反馈差分参考信号接收功率时：
所述的差分参考信号接收功率的参考功率可以是以下至少之一：所述J个参考信号下，特定参考信号的参考信号接收功率；基站配置的差分参考信号接收功率报告的参考值。所述J个参考信号外，特定参考信号的参考信号接收功率。
对于上述的情况a)到情况c)中，所述的特定参考信号为分组内部参考信号下，具有最大或者最小参考信号接收功率的参考信号；或者，所述的特定参考信号为所有参考信号下，具有最大或者最小参考信号接收功率的参考信号。
此外，对于差分参考信号接收功率反馈而言，除了参考值外，差分报告的步进量也非常重要。而，所述的差分参考信号接收功率下的步进量，可以通过以下至少之一或组合进行配置：预定义的步进量；根据差分参考信号接收功率的参考功率，确定步进量；根据差分参考信号接收功率的 参考功率和第二通信节点配置的门限，确定步进量。
而执行差分参考信号接收功率反馈的条件，包括至少如下之一：1)
参考信号类型；2)所述的参考信号数目。例如，对于同时支持CSI-RS和SS block进行反馈时，可以仅CSI-RS支持差分报告，而SS block不支持差分报告。或者，CSI-RS和SS block可以分别进行差分报告，这意味着CSI-RS和SS block在差分报告时，RSRP的参考值可以不相关。
例如，基站端配置了6个CSI-RS resource用于波束训练，而后配置相关资源用于UE端反馈beam reporting，其中允许反馈2个波束资源，并所述的2个波束资源需要满足可以同时接收的假设，即反馈一个波束分组。经过对于6个CSI resource进行信道测量后，UE端获得了相对应的RSRP结果如表3所述。同时，CRI-0和CRI-5可以同时接收，CRI-1和CRI-2和CRI-3和CRI-4可以同时接收。
表3
CRI-0 -79dBm
CRI-1 -60dBm
CRI-2 -66dBm
CRI-3 -74dBm
CRI-4 -95dBm
CRI-5 -100dBm
UE端选择了{CRI-1和CRI-2}执行波束分组上报，这时，CRI-1作为在该分组内部具有最大RSRP的参考信号索引，RSRP值{-60dBm}采用绝对或者非差分的RSRP报告；而，CRI-2的RSRP值[-66dBm]使用相对的RSRP报告。根据表2所描述的差分步进关系，则CRI-2下的相关报告为[CRI-2,-6dBm(i.e.,4’b0110)]。因此，该报告的内容信息如下：{[CRI-1,-60dBm],[CRI-2,-6dBm(i.e.,4’b0110)]}
若基站配置了UE执行4个波束资源反馈，并所述的4个波束资源需要 满足可以同时接收的假设，即反馈一个波束分组。同时，基站配置了波束选择的下限为-90dBm。当差分的步进配置为：分组内部最高的RSRP和基站配置下限的差值时，考虑一共有4-bit可以使用，则步进量计算公式如下：
Step value＝{Max of RSRP–Threshold}/(2^n-1)
其中，Step value表示步进量；Max of RSRP表示最大的RSRP或者是分组内最大的RSRP，或者是参考的RSRP值；Threshold，表示基站配置的门限；而n表示差分报告的比特数。带入公式后，我们有步进量为(-60-(-90))/15＝2dB。另外，考虑CRI-4不满足门限要求，所以UE端仅报告了3个波束信息(即3个参考波束索引)。具体报告信息如下：{[CRI-1,-60dBm],[CRI-2,-6dBm(i.e.,4’b0011)]}{[CRI-3,-14dBm(i.e.,4’b0111)]}。
在一实施例中，第二通信节点(gNB)指示下的波束反馈。
对于基站配置的用于波束训练的参考信号，优先级可能不同。这主要是因为，一些参考信号可以是用于支持当前的服务波束或者可选波束集合；而，其他参考信号，可能仅仅是用于一般意义上的波束训练，发现新的潜在波束。在这种情况下，基站可以指定特定波束，要求UE一定进行上报，或者优先上报。
对于所述的第二通信节点(即基站)发送的参考信号，第二通信节点的配置参考信号的报告模式，其中报告模式包括如下至少之一或组合：第一报告模式；第二类报告模式；其中，第一报告模式比第二类报告模式有更高的优先级(或者，要求一定反馈波束报告)；或者，在第一报告模式下的门限，小于第二类报告模式下的门限。具体而言，在第一报告模式下，报告所关联的参考信号的参考信号相关索引和/或参考信号接收功率；在第二类报告模式下，可以报告或者可以不报告，所关联的参考信号的参考信号相关索引和/或参考信号接收功率。
在一实施例中，由于第一报告模式下参考信号一定需要被反馈，所以UE端可以不同反馈其对应的索引信息，而直接通过隐式的方法来反馈对应 关系，例如通过参考信号接收功率的顺序位置指示所述的参考信号索引。
对于如何来支持差分RSRP报告而言，第一报告模式与第二类报告模式，分别执行差分参考信号接收功率反馈；或者，第一报告模式下，使用绝对参考信号接收功率反馈，而第二类报告模式下，使用差分参考信号接收功率反馈；或者，第二类报告模式下，使用绝对参考信号接收功率反馈，而第一报告模式下，使用差分参考信号接收功率反馈。在一实施例中，第一报告模式与第二类报告模式，分别执行差分参考信号接收功率反馈，或者差分报告中步进量不同，或者步进量可以分别被配置。
在一实施例中，侧重于根据UE的能力来限制基站配置范围。
根据UE端能力的不同，基站侧可以配置的参数需要进行有效的限制，这一方面可以节省配置信令的开销，同时，也会利于信道质量反馈时不必要反馈资源的花费，和避免配置用户端无法支持的配置行为。
本发明实施例提供了一种配置信息的方法，应用于第二通信节点，包括如下至少之一：
由第一通信节点的能力，第二通信节点确定配置约束，涉及至少如下之一或组合：物理上行控制信道(PUCCH)，物理随机接入信道(PRACH)，波束恢复的物理随机接入信道(PRACH)，第一类信令次数门限，累计时间门限。
在一实施例中，第一通信节点的能力涉及如下至少之一或组合：支持波束关联(beam correspondence)；支持非波束关联(non beam correspondence)；支持部分波束关联；天线参数。
在一实施例中，所关联的下行参考信号满足信道特性假设的物理随机接入信道(PRACH)分配在相同的时域单元。其中，所述的时域单元，包括时隙、子帧、符号或者符号集合。
在一实施例中，所述的天线参数，包括如下之一或组合：
1)天线端口的数目；
2)2-D天线组码本的维度大小和2-D天线组码本的个数；
3)天线组下的2D波束码本的维度大小和2-D波束码本个数；
4)面向大带宽的码本的维度大小和面向大带宽的码本的个数；
5)面向小带宽的码本的维度大小和面向小带宽的码本的个数；
6)面向极化的码本的维度大小和面向极化的码本的个数；
7)码本量化的精度大小；
8)下行接收码本是否和2)～5)中全部或任一码本之间关联；
9)天线面板的个数；
10)天线面板的行数；
11)天线面板的列数；
12)天线面板的拓扑形状；
13)天线面板下的天线元素的行数；
14)天线面板下的天线的列数；
15)天线极化特征。
综上所述，基于本发明实施例提供的技术方案，对于用户主动的波束上报和基站指示的波束上报进行配置限制和绑定配置，具体包括，对于PRACH和PUCCH资源配置的限定和捆绑，用户主动的波束上报的时间约束配置，基站指示的波束反馈和分组反馈下RSRP差分报告和绝对RSRP报告的配合方法，可以有效提升波束上报的效率和节省配置和实际现实下的花销。
