背景技术
超宽带宽的高频段通信(也可以称为毫米波通信)，成为未来移动通信发展的重要方向，吸引了全球的学术界和产业界的目光。特别是，在当下日益拥塞的频谱资源和物理网大量接入时，毫米波的优势变得越来越有吸引力，在很多标准组织，比如电气和电子工程师协会(IEEE，Institute of Electrical and Electronics Engineers)、第三代合作伙伴计划(3GPP，3rd Generation Partnership Project)都开始展开相应的标准化工作。比如，在3GPP标准组，高频段通信凭借着其大带宽的显著优势将会成为5G新无线接入技术(New RAT，New Radio Access Technology)的重要创新点。
然而，高频段通信也面临着链路衰减的挑战。面对这些挑战，高频段通信***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(也可以称为定向波束通信)来获取高天线增益和对抗信号传输损耗，进而确保链路余量和提升通信鲁棒性。
然而高频段通信***中，定向波束通信在获得链路增益的同时，也降低了信号在空间传播的分集，从而可能会受终端移动和信道遮挡的影响，导致定向通信的鲁博性相对较差。在一些场景下，还会导致波束链路失败， 从而使得再次通信时的无线通信可靠性及及时性无法保证。对于此问题，相关技术尚无有效解决方案。

具体实施方式
下面结合附图及实施例对本公开再作进一步详细的描述。
超宽带宽的高频段通信由于其带宽的优势成为当下关注的重点。然而，高频段通信面临着包括传播路径损失大、空气吸收(尤其是氧气)吸收更大、雨衰影响较重等链路衰减的挑战。面对这些挑战，高频段通信***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，进而确保链路余量和提升通信鲁棒性。
其中，高频段通信***中，在天线权重(也称为预编码、波束)训练过程中，首先，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，接收端需要向发送端反馈信道状态信息，便于实现收发端在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，以提升整体的频谱效率。
目前，在高频段通信***中采用定向波束通信方式获得链路增益的同时，也降低了信号在空间传播的分集，从而可能会会受终端移动和信道遮挡的影响。在一些特定场景，比如在终端快速移动的场景，或者对于不连续接收(DRX)时，可能会导致波束链路失败，从而导致再次通信时无线通信可靠性及及时性无法保证。
需要说明的是：波束链路失败后可以进行无线接入流程，即执行RLF流程，但是该过程会给无线通信造成比较大的时延，所以波束链路失败后如何能够降低时延，并没有相关技术方案。
另外，对于承载波束链路的时频资源是否可以和其他业务共享复用，也没有给出有效的解决方案。
基于此，在本公开的各种实施例中：当波束链路失效时，第一通信节点使用分配的上行资源向第二通信节点发送通知第二通信节点波束链路失效的第一类上报信息，以便第二通信节点能够及时获知波束链路失效，从 而能够加速第一通信节点和第二通信节点发现一个有效的波束组合。
另外，为了节省资源，第一通信节点可以使用分配的上行资源发送上行参考信号和上行控制信令。
其中，实际应用时，所述上行是指：终端向基站发送信息的方向；相应地，下行是指基站向终端发送信息的方向。
所以，第一通信节点是指终端，第二通信节点是指基站。本公开实施例的方案，还可以理解为：基站向终端分配上行资源，用于承载波束恢复(用英文可以表达为beam recovery)信令。其中，为了减少资源的浪费，终端可以使用该上行资源发送上行参考信号或者其他上行控制信令(例如调度请求等)，但当发生BLF时使用该上行资源承载beam recovery信令。也就是说，发送beam recovery信令的优先级是最高的。
实施例一
本公开实施例提供的信息的上报方法，如图1所示，应用于第一通信节点，该方法包括：
步骤101：判定波束链路失效条件成立时，生成第一类上报信息；
这里，所述第一类上报信息至少用于通知第二通信节点波束链路失效。
实际应用时，所述波束链路失效条件，是指波束相关参数或者参数组合满足门限条件。举个例子来说，所述波束链路失效条件可以为如下：
1)O个未标示波束链路的质量大于或等于一个公共门限或者各自门限；
2)O个未标示波束链路的质量与K个已标示的波束链路质量和的差值或者比值大于或等于一个公共门限或者各自门限；
3)O个未标示波束链路与K个已标示的波束链路的时频信道响应的相关性、频域信道响应的相关性，或者空域相关性低于一个公共门限或者两两分别门限；
4)O个未标示波束链路的方位角与K个已标示的波束链路的方位角的差值或者比值大于一个公共门限或者两两分别门限；
5)K个已标示的波束链路质量小于一个公共门限或者各自门限；
6)全部已标示的波束链路质量小于一个公共门限或者各自门限；
7)距离上次控制信道/数据信道成功接收的时间累计大于一个公共门限或者各自门限；
8)未成功接收的累计次数大于一个公共门限或者各自门限；
9)波束分组的调整信息；
10)以上部分参数的加权值，或者加权相关值。
其中，实际应用时，所述已标示和未标示可以是通过对于参考信号的不同配置指示来实现的。O和K为正整数，可以根据需要确定其具体取值。
需要说明的是：本公开实施例并不对波束链路失效条件作限定，实际应用时，可以根据需要设置其它波束链路失效条件。
步骤102：使用已分配的第一上行资源向第二通信节点发送所述第一类上报信息。
所述第一类上报信息可以称为波束恢复信令。
实际应用时，波束恢复信令可以由两个比特或者四类参考信号序列构成，以表达链路是否失效，承载第一类上报信息的上行资源所关联的下行参考信号是否是新可用波束，即[链路失败，该关联下行参考信号是新可以用波束]，具体而言：
第一种情况：波束链路未失效(即non-BLF)时：上行资源可以用于承载PUCCH和/或SRS，进行上行波束训练。
此时，波束恢复信令的具体内容可以是：[链路失败，该关联下行参考信号是新可以用波束]＝[0,0]。
第二种情况：波束链路失效并且未发现潜在可用波束时:上行资源可以用于承载PUCCH，进行上行波束训练。
此时，波束恢复信令的具体内容可以是：[链路失败，该关联下行参考信号是新可以用波束]＝[1,0]。
第三种情况：波束链路失效，并且发现潜在可用波束。
此时，波束恢复信令的具体内容可以是：[链路失败，该关联下行参考信号是新可以用波束]＝[1,1]。
第四种情况：波束链路未失效(即non-BLF)时：发现一个有效下行波束。
此时，波束恢复信令的具体内容可以是：[链路未失败，该关联下行参考信号是新可以用波束]＝[0,1]。
实际应用时，根据波束恢复信令的具体内容，第二通信节点可以获知是上述哪种情况。
其中，第二通信节点获知关联下行参考信号有以下三种可能的方式：
1)发送波束恢复信令的时频资源位置，就关联下行参考信号
2)在承载波束恢复信令的PUCCH上已经显式承载关联；
3)第二通信节点确认承载波束恢复信令对应的请求后，第一通信节点可以在之后的位置PUCCH再上传关联下行参考信号。
其中，对于上述第二种方式，实际应用时，可以不需要所有分配的上行资源都用于发送波束恢复信令，可以由第二通信节点(即基站)和第一通信节点(终端)协商，用哪些资源来发送波束恢复信令，这样有利于降低基站的实现复杂度，给予基站一定的灵活性。换句话说，对于分配的上行资源，终端是不是可以用于做上行波束训练，这个是基站配置的，和/或终端有一个准则。
也就是说，一种实现方式是：上行波束资源可用于做波束训练，也可以用于进行波束恢复信令承载。但是不是所有这样的资源都需要具备这个功能，例如周期分配做波束训练的资源，某些资源上只能做正常的波束训练，某些资源终端可以根据当时的情况二选一(即用于上行波束训练或者承载波束恢复信令)。
基于此，实际应用时，所述第一上行资源是可以具有周期特征的，且满足时间约束。
其中，时间约束是指，所分配的第一上行资源仅在有限时间范围内是有效的，即所配置的第一上行资源(比如PUCCH)是具有实效性的，如此， 能节省不必要的资源花费。
其中，在一具体实施例中，该方法还可以包括：
使用第二上行资源执行以下操作至少之一：
发送上行参考信号；
发送上行控制信令；
其中，所述第二上行资源为所述第一上行资源的一个子集。
这里，当第二上行资源上需要发送上行参考信号和上行控制信令中至少之一与发送所述的第一类上报信息碰撞时，只发送所述第一类上报信息。换句话说，优先发送所述第一类上报信息。
实际应用时，所述上行参考信号可以包括以下之一：
DMRS；
SRS；
随机接入序列信号，即随机接入信道信号(RACH)；
已分配的专属序列。
其中，所述已分配的专属序列可以是对应PRACH-like。
实际应用时，上行参考信号还可以为相位追踪参考信号(PT-RS)。
在一具体实施例中，使用第二上行资源执行所述操作时，该方法还可以包括：
通过隐式或显示的方式，指示所述波束链路未失效。
其中，所述通过隐式的方式，指示所述波束链路未失效，包括：
使用特定序列，或者使用第一类上报信息中的保留字段，指示所述波束链路未失效。
在一具体实施例中，所述第一类上报信息还可以承载以下信息至少之一：
与承载所述第一类上报信息的时频资源所关联的下行参考信号是否是可用波束的指示信息；
所述第一通信节点的身份信息；
可用波束索引。
其中，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)；波束符号可以被替换为资源索引，这是因为波束可以与一些时频码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；所述传输方式可以包括空分复用、频域/时域分集等。
所述波束指示是指，第一通信节点可以通过当前参考信号和天线端口，与第二通信节点扫描或者第一通信节点反馈报告的参考信号(或基准参考信号)和天线端口满足准共址(QCL)假设来进行指示。
这里，所述QCL涉及的参数至少包括：多普勒扩展，多普勒平移，时延拓展，平均时延和平均增益。可能还包括：空间参数信息，例如到达角，接收波束的空间相关性，平均时延，时频信道响应的相关性(包括相位信息)。
所述身份信息可以是：介质访问控制(MAC)地址，小区无线网络临时标识(C-RNTI)，临时C-RNTI(TC-RNTI)，或第二通信节点(即基站)分配给第一通信节点(即终端)的专属ID等。当然，实际应用时，所述身份信息还可以是其它能够标识第一通信节点身份的其它信息，只要能够标识第一通信节点的身份即可，本公开实施例对此不作限定。
由于发现新潜在波束时，有多种类型的参考信号可以被使用，例如SS(例如主同步信号(SSS)、副同步信号(PSS))、CSI-RS、DMRS等。而为了便于管理和节省开销，可以将多种类型的参考信号进行联合编码，使用统一的序号，从而使得这些参考信号使用统一波束索引。举个例子来说，第二通信节点可以配置用于波束恢复的CSI-RS和SS资源进行联合编码，使用一个统一索引序号，承载在波束恢复信令上；例如ID：0-4 SS；5～15CSI-RS。
这样，采用联合编码时，至少两种类型的下行参考信号重新编号，使用统一索引。
其中，所述下行参考包括以下至少之一：
SS；DMRS；CSI-RS。
实际应用时，所述下行参考信号还可以包括以下至少之一：
小区参考信号(CRS)；
波束管理的信道状态信息参考信号；
信道状态信息干扰测量信号(CSI-IM)；
PT-RS；
移动相关参考信号(MRS)；
波束参考信号(BRS)；
波束细化参考信号(BRRS)；
RACH；
同步信号块(SS block)；
PSS；
SSS。
实际应用时，与承载所述第一类上报信息的时频资源所关联的DMRS可以满足以下条件至少之一：
为PBCH所关联的DMRS；
公共控制信道所关联的DMRS。
由于不同类型的参考信号的发送功率的不同，所以不同类型的参考信号所对应的反馈门限是可以不同的，也可以是可变的，或者门限可配置，这样，每种类型的下行参考信号满足以下条件至少之一：
每种类型的下行参考信号使用各自的专属测量门限；
每种类型的下行参考信号使用各自的专属上报门限。
实际应用时，当考虑波束关联(采用英文可以表达为beam correspondence)的情况时，在beam correspondence或存在信道互异性时，所述第一上行资源与所述索引存在上下行参考信号之间的绑定关系。
其中，波束恢复信令可以仅显示承载终端ID信息；或者，终端ID信号和下行参考信号之间联合编码，隐式体现终端ID信息。
这里，所述上下行参考信号之间的绑定关系(即关联关系)是指：上行参考信号的空间参数(spatial parameter)特性可以通过下行参考信号所经历信道的spatial parameter特性进行判定。反过来说，下行参考信号的spatial parameter特性可以通过上行参考信号所经历信道的spatial parameter特性进行判定。这种特性也称为满足QCL假设，或者满足空间互异性QCL假设。具体来说，上行参考信号发送波束可以通过下行参考信号所对应的接收波束来确定；下行参考信号发送波束可以通过上行参考信号所对应的接收波束来确定；上行参考信号接收波束可以通过下行参考信号所对应的发送波束来确定；下行参考信号接收波束可以通过上行参考信号所对应的发送波束来确定。
其中，所述接收波束是指：无需指示的接收端的波束，或者第一通信节点可以通过当前参考信号和天线端口，与第二通信节点扫描或者第一通信节点反馈报告的参考信号(或基准参考信号)和天线端口的QCL指示下的接收端的波束资源。
在无波束关联(non beam correspondence)或不存在信道互异性时，在第一上行资源中N个上行波束资源被分成一组，其中第一通信节点在所述上行资源分组中使用相同的上行预编码或者发送波束。
也就是说，在无波束关联或不存在信道互异性时，所述第一上行资源中，每N个上行波束资源被分成一组，形成M组；所述第一通信节点在每个分组中使用相同的上行预编码或者相同的发送波束；N、M均为大于或等于1的整数。
其中，所述分组是指：具有相同信道特性和/或传输方案的波束和相关的信道状态信息划分成一个集合。所以组也可以称为集合。
这里，所述信道特征，既包括物理传播信道特征，例如水平发送方位角，垂直发送方位角，水平接收方位角，垂直接收方位角等，也包括射频和基带电路的特征，例如天线阵子特征(element pattern)，天线组，天平面板，天线子阵列(antenna subarray)，收发单元(TXRU)，接收波束集合， 天线摆放，以及基带时偏，频偏和相位噪声等。
实际应用时，可以根据以下至少一种分组准则，将每N个上行波束资源分成一组(即每组准则包括以下任意一种以及任意几种的组合模式)：
接收方式；
接收波束组合；
天线组；
接收信号功率；
水平发送方位角；
垂直发送方位角；
水平接收方位角；
垂直接收方位角；
平均到达时间；
簇到达时间；
所述第一上行资源对应的接收资源；
预定复用方式；
TA参数；
CP长度；
空分复用方式；
准共位置关系。
实际应用时，波束链路失效条件成立时，是执行波束恢复流程还是执行无线接入流程，即执行RLF流程，可以将是否上行同步作为一个重要的判断指标。举个例子来说，在仅仅分配PUCCH资源用于波束恢复时，当上行同步时，执行波束恢复流程；当上行失去同步时，执行无线接入流程。
这里，当PUCCH和PRACH或PRACH-like资源同时被配置用于波束恢复时：PUCCH的使用条件是：有固定的UE ID并且上行同步；相应地，PRACH或PRACH-like使用条件是：没有固定的UE ID或者上行失去同步。
换句话说，当已分配承载所述第一类上报信息的专属资源，且上行同步时，所述第一类上报信息使用PUCCH承载；当上行失去同步时，第一通信节点执行无线链路失效RLF流程。
当未被分配承载所述第一类上报信息的专属资源，或者上行失去同步时，所述第一类上报信息使用PRACH或者PRACH-like承载。
其中，所述PRACH-like是指：通过长前导和序列的方法来承载信息，不同的序列标示不同的信息类型。这种模式，在上行不同步的情况下，可以有效保障上行信号的传输，并且避免对于其他用户上行信号的干扰。
在一具体实施例中，使用已分配的第一上行资源向第二通信节点发送所述第一类上报信息时，该方法还可以包括：
将所述第一类上报信息和调度请求信令联合编码，比如使用调度请求+1bit/2bit；
或者，将所述第一类上报信息和调度请求分配在相同的上行控制信令中。
对应地，本公开实施例还提供了一种信息的接收方法，应用于第二通信节点，如图2所示，该方法包括：
步骤201：接收第一通信节点发送的第一类上报信息；所述第一类上报信息是使用已分配的第一上行资源发送的；
步骤202：利用配置的时频域资源向所述第一通信节点发送确认信令；所述配置的时频域资源为下行控制信道搜索空间的时频域资源。
其中，所述第一类上报信息还承载一个可用波束信息时，利用配置的时频域资源向所述第一通信节点发送确认信令时，发送所述确认信令的发送波束为所述可用波束信息对应的发送波束。
所述第一类上报信息还承载至少两个可用波束信息时，发送所述确认信令的发送波束为以下之一：
第一个可用波束；
特定位置的可用波束；
在预先设定准则下，分别使用各可用波束发送(比如周期性地分别使用各可用波束发送)。
这里，实际应用时，第二通信节点(即基站)可以向第一通信节点(即终端)配置一个波束恢复配置信令，表示每个第一通信节点发送的波束恢复信令可以承载的波束的个数需要小于或等于L个。L为大于或等于1的整数。
当第一通信节点通过波束恢复信令(第一类上报信息)向第二通信节点反馈的可用发送波束仅一个时，第一通信节点默认将使用该发送波束所对应的下行接收波束进行接收。当向第二通信节点反馈至少两个可用发送波束信息时(需要说明，这些多个波束可以在一个信令中承载的，也可以通过多个时频域上的波束恢复信令分别承载)，按照特定准则基站将时分和/或频分来发送确认信令。
当可用的发送波束为至少两个时，至少两个发送波束分时发送确认信令。
举个例子来说，时间0～x1内，使用第一个波束(beam 1)；时间x1～x2内，使用第一个波束(beam2)；以此类推等等。
再比如，还可以是多个发送波束来轮询发。
本公开实施例提供的信息的传输方法，如图3所示，包括以下步骤：
步骤301：第一通信节点判定波束链路失效条件成立时，生成第一类上报信息；
这里，所述第一类上报信息至少用于通知第二通信节点波束链路失效；
步骤302：第一通信节点使用已分配的第一上行资源向第二通信节点发送所述第一类上报信息；
步骤303：第二通信节点接收到所述第一类上报信息后，利用配置的时频域资源向所述第一通信节点发送确认信令。
这里，所述配置的时频域资源为下行控制信道搜索空间的时频域资源。
需要说明的是：第一通信节点和第二通信节点的具体处理过程已在上 文详述，这里不再赘述。
本公开实施例提供的信息的上报、接收方法，判定波束链路失效条件成立时，第一通信节点生成第一类上报信息；所述第一类上报信息至少用于通知第二通信节点波束链路失效；使用已分配的第一上行资源向第二通信节点发送所述第一类上报信息；第二通信节点收到所述第一类上报信息后，利用配置的时频域资源向所述第一通信节点发送确认信令；所述配置的时频域资源为下行控制信道搜索空间的时频域资源，当波束链路失效时，由于第一通信节点及时通知了第二通信节点，所以就能够加速第一通信节点和第二通信节点发现一个有效的波束组合，即建立波束链路。
另外，使用第二上行资源执行以下操作至少之一：发送上行参考信号；发送上行控制信令(比如调度请求等)；其中，所述第二上行资源为所述第一上行资源的一个子集。如此，配置的承载波束链路的上行资源能够和其它业务能共享复用，大大节省了资源。
实施例二
为实现本公开实施例的方法，本实施例提供一种信息的上报装置，设置在第一通信节点上，如图4所示，所述装置包括：

其中，所述第二上行资源为所述第一上行资源的一个子集。
这里，实际应用时，当第二上行资源上需要发送上行参考信号和上行控制信令中至少之一与发送所述的第一类上报信息碰撞时，所述第一发送 单元42只发送所述第一类上报信息。换句话说，优先发送所述第一类上报信息。
在一具体实施例中，所述第一发送单元42，使用第二上行资源执行所述操作时，通过隐式或显示的方式，指示所述波束链路未失效。
其中，所述通过隐式的方式，指示所述波束链路未失效，包括：
所述第一发送单元42使用特定序列，或者使用第一类上报信息中的保留字段，指示所述波束链路未失效。
在一具体实施例中，所述第一发送单元42，还配置为使用已分配的第一上行资源向第二通信节点发送所述第一类上报信息时，
将所述第一类上报信息和调度请求信令联合编码，比如使用调度请求+1bit/2bit；
或者，将所述第一类上报信息和调度请求分配在相同的上行控制信令中。
上述实施例提供的信息的上报装置在进行信息的上报时，仅以上述各程序模块的划分进行举例说明，实际应用中，可以根据需要而将上述处理分配由不同的程序模块完成，即将装置的内部结构划分成不同的程序模块，以完成以上描述的全部或者部分处理。另外，上述实施例提供的信息的上报装置与信息的上报方法实施例属于同一构思，其具体实现过程详见方法实施例，这里不再赘述。
本公开实施例还提供了一种信息的上报装置，如图5所示，该信息的上报装置包括：处理器51和配置为存储能够在处理器51上运行的计算机程序的存储器52，
其中，所述处理器51配置为运行所述计算机程序时，执行：

下面结合具体实施例来进一步详细说明本公开。
具体实施例一
基站向终端配置了多个参考信号用于发现新波束，配置的多个参考信号包括SS block和CSI-RS。其中，SS block包括PSS、SSS和PBCH信号。
其中PBCH信号中存在与之关联的DMRS信号。
图9为本公开具体实施例一针对CSI-RS和SS的波束恢复信令示意图。如图9所示，在波束恢复信令窗口，可以使用多种类型的参考信号来发现潜在的可用波束，而可用波束信息将会被承载在波束恢复信令中。为了支持多种类型的参考信号，多种类型的参考信号即SS和CSI-RS(或者PBCH的DMRS)会被联合编码，使用一组共同的终端ID信息，即使用一个统一的索引序号。
具体实施例二
本实施例中，通过PUCCH承载波束恢复信令。
承载波束恢复信令的时频域资源，即波束恢复信令所在的时频资源的位置与终端ID信息关联，也就是通过解析相应的时频域资源，就可以知道是那个UE发送的波束恢复信令。
但是，在存在beam correspondence和不存在beam correspondence的两种情况下，用户的行为特征将会有调整。为了保证波束恢复的有效性，承载波束恢复信令的资源将具有周期特性，但是需要有一定的时间约束。即在基站配置该时频资源时，该时频资源仅在一个有限时间范围内有效。
图10a为本公开实施例在non beam correspondence时通过PUCCH承载波束恢复信令示意图。如图10a所示，当终端认为下行参考信号x可以发现一个有效的下行波束时，终端会尝试从其所对应的多个上行波束恢复资源窗口上发送波束恢复信令。终端会尝试在其不同时域下的PUCCH资源上切换对应的上行波束，来实现上行波束训练。基站在确认PUCCH有效接收后，会使用其所隐含指示的下行发送波束来发送波束恢复确认信令。即这种情况下，可将潜在波束发现的下行参考信号和多个不同时域的波束恢复 信令的时域资源关联。
图10b为本公开实施例在beam correspondence时通过PUCCH承载波束恢复信令示意图。如图10b所示，波束恢复信令专属的时频资源和可用于潜在波束发现的下行参考信号关联。同时，基站将会使用与该下行参考信号关联的发送波束所对应的接收波束来接收波束恢复信令。在波束链路失效发生时，终端将会使用与接收该下行参考信号所关联的上行发送波束/参考信号资源来发送波束恢复信令，但当波束链路未失效时，终端可以尝试使用与该下行参考信号所关联的上行发送波束所不同的发送波束来发送信令，可以用于上行波束训练和信道估计。
图10c为波束恢复信令可以使用hopping模式(即调频模式)对应上行资源示意图。在对应于关联相同的下行参考信号资源的同一终端的上行发送资源，在不同的时域单元上不必一致，可以满足特定的函数下进行跳转。这样可以在一定程度上避免波束恢复信令一致位于频域选择性信道衰落区。需要说明的，即使在beam correspondence场景下，也可以将承载的波束恢复信令的相关比特信息分配到不同的时频资源位置上来。
具体实施例三
在本实施例中，通过波束恢复信令字段进行上行信道估计和发送上行信令。
图11为本公开实施例通过波束恢复信令字段进行上行信道估计和发送上行信令示意图。如图11所示，波束恢复信令所关联的DMRS，可以用于上行波束训练或者基站端上行的参考信号接收功率(RSRP)估计。例如，信令为[链路失败，该关联下行参考信号是新可用波束]＝[1/0,0]，或者[该关联下行参考信号是新可用波束]＝[0](即，仅在波束链路失效时才发送该信令)。若指示波束链路失败未发生时，该字段可用于上行信道估计，可以提升上行信噪比，或者关联上行信道的RSRP反馈和调度请求。若在波束链路失效时，该模式意味着上行和下行的联合波束训练，在尚未发现有效下行链路时，终端就利用这些资源发起对于上行波束的扫描，加速整个波束恢复的进程。需要说明的是，在这种情况下，之后下行波束恢复确认信令 的搜索空间发送波束，需要和该信令所关联。
具体实施例四
在本实施例中，存在两个波束恢复信令的承载资源，其一是上行PUCCH，其二是PRACH/PRACH-like时频资源。如果若PUCCH和PRACH/PRACH-like资源同时被基站配置，用于承载波束恢复信令时，PUCCH使用条件的是：有固定的UE ID并且上行同步；PRACH或者PRACH-like使用条件是：没有固定的UE ID或者上行失步。此外，PUCCH可以通过显式或者隐式的方法来指示多种类型的参考信号索引，而PRACH/PRACH-like字段仅可以通过隐式关联的方法承载与SS block相关联的参考信号索引。
图12a为本公开实施例在non beam correspondence时波束恢复方法流程示意图。如图12a所示，在non beam correspondence这种情况下，PUCCH可以显式承载下行波束序号，上行重复发送的方法来探测上行有效波束。其中，下行波束索引有两个可行方法，其一首先指示参考信号类型，然后指示该参考信号索引；或者，通过联合编码的办法，直接指示所特定的参考信号类型。
图12b为本公开实施例在beam correspondence时波束恢复方法流程示意图。如图12b所示，在beam correspondence这种情况下，基站首先会默认承载上行波束恢复信令的时频资源和下行参考信号资源之间存在关联。因此，终端仅需在与该参考信号相关联的信令上承载波束恢复信令。
具体实施例五
本实施例描述波束恢复信令承载多个可用波束时，波束恢复确认信令的发送方法。图13为本公开实施例的波束恢复信令承载多波束下的波束恢复确认信令流程。Non beam correspondence和beam correspondence两种情况所关联的流程分别如图13a和图13b所示。
如图13a所示，在non beam correspondence时，终端指示的两个可用波 束信息会分别对应不同的搜索空间窗口。如果终端在搜索空间1窗口中已经收到基站信令，将放弃对于搜索空间2的搜索，并且会在基站所指定的时频资源位置下发送上行信令进行确认(甚至可以承载进一步的下行波束报告)。如果用户在搜索空间1中未收到基站确认信令后，会尝试在搜索空间2进行进一步搜索。
如图13b所示，在beam correspondence时，将存在两级的关联，即下行参考信号(CSI-RS和SS block)和PUCCH波束恢复信令之间的下行上行参考信号关联(这里，上行参考信号对应于PUCCH波束恢复信令的DMRS信号)，和PUCCH波束恢复信令和下行控制信道搜索空间之间的上行下行参考信号的关联。特别是对于后者而言，实现了与之前发送的下行CSI-RS或者SS block参考信号相关联，即PDCCH的DMRS信号与波束恢复信令所指示的CSI-RS或者SS block满足QCL假设。
综上所述，本公开实施例提供的技术方案，基站对终端配置波束恢复时频资源，用于承载波束恢复请求信令。在终端未发送波束链路失效时，终端可以使用该资源承载上行波束扫描(即发送上行参考信号)和发送上行控制信令；在终端发生波束链路失效，但是未发现有效下行波束链路时，终端会使用该资源承载波束恢复信令，并且进行上行波束训练，可以加速终端和基站发现一个有效波束组合；在终端发生波束链路失效并且发现有效下行波束链路时，终端可以在该时频资源上承载下行波束信息。通过本公开实施例的方案，一方面，终端可以在波束链路失效后快速的告知基站，通过利用专属上行资源加速波束恢复的进程；另一方面，在未承载波束恢复信令时，可以用于上行波束扫描(即发送上行参考信号)和上行控制信令的发送。
以上所述，仅为本公开的较佳实施例而已，并非用于限定本公开的保护范围。
工业实用性
本公开实施例提供的方案，第一通信节点判定波束链路失效条件成立；生成第一类上报信息；所述第一类上报信息至少用于通知第二通信节点波 束链路失效；使用已分配的第一上行资源向所述第二通信节点发送所述第一类上报信息；第二通信节点收到所述第一类上报信息后，利用配置的时频域资源向所述第一通信节点发送确认信令；所述配置的时频域资源为下行控制信道搜索空间的时频域资源，当波束链路失效时，由于第一通信节点及时通知了第二通信节点，所以就能够加速第一通信节点和第二通信节点发现一个有效的波束组合。
