具体实施方式
在下文中将结合附图对本公开的示范性实施例进行描述。为了清楚和简明起见，在说明书中并未描述实际实施方式的所有特征。然而，应该了解，在开发任何这种实际实施例的过程中必须做出很多特定于实施方式的决定，以便实现开发人员的具体目标，例如，符合与系统及业务相关的那些限制条件，并且这些限制条件可能会随着实施方式的不同而有所改变。此外，还应该了解，虽然开发工作有可能是非常复杂和费时的，但对得益于本公开内容的本领域技术人员来说，这种开发工作仅仅是例行的任务。
在此，还需要说明的一点是，为了避免因不必要的细节而模糊了本 公开，在附图中仅仅示出了与根据本公开的方案密切相关的设备结构和/或处理步骤，而省略了与本公开关系不大的其它细节。
下面结合附图详细说明根据本公开的实施例。
图1示出了根据本公开的一个实施例的用于无线通信的电子设备100的功能模块框图，如图1所示，电子设备100包括：第一接收单元102，可以被配置成从为电子设备100提供服务的基站接收用于监测波束是否故障的下行信号；以及第一判定单元104，可以被配置为在下行信号中的任一下行信号所表征的信道质量以预定偏差值低于由电子设备确定的候选下行信号所表征的信道质量的次数达到第一计数值时，判定与该任一下行信号对应的波束为故障波束，并且向基站发送波束故障恢复请求，以对故障波束进行恢复。
其中，第一接收单元102和第一判定单元104可以由一个或多个处理电路实现，该处理电路例如可以实现为芯片。
电子设备100例如可以设置在用户设备(UE)侧或者可通信地连接到UE。这里，还应指出，电子设备100可以以芯片级来实现，或者也可以以设备级来实现。例如，电子设备100可以工作为用户设备本身，并且还可以包括诸如存储器、收发器(图中未示出)等外部设备。存储器可以用于存储用户设备实现各种功能需要执行的程序和相关数据信息。收发器可以包括一个或多个通信接口以支持与不同设备(例如，基站、其他用户设备等等)间的通信，这里不具体限制收发器的实现形式。
监测波束是否故障指的是监测电子设备100和基站之间的、利用该波束进行通信的链路是否存在故障。在下文中，有时也将波束故障称为波束失败。
作为示例，用于监测波束是否故障的下行信号可以是用于监测波束是否故障的下行参考信号(该下行参考信号可以是周期性的CSI-RS(信道状态信息参考信号)或者SSB(同步信号块))。可以将用于监测波束是否故障的下行信号简称为BFD RS(波束失败检测参考信号)，BFD RS可以被包括在称为q0的参考信号集合(该参考信号集合由CSI-RS和/或SSB构成)中。参考信号集合q0可以包含最多两个BFD RS(分别标记为RS0和RS1)，其中每一个BFD RS都会和一个CORESET(控制信道资源集)的DMRS(解调参考信号)是QCL(准共址)关系，并且每个 BFD RS可以是CSI-RS或者SSB。上述“任一下行信号”可以是例如RS0和RS1中的任一信号，例如，“任一”可以指以下三种情况：只有RS0、只有RS1、以及RS0和RS1两者，相应地，“与该任一下行信号对应的波束为故障波束”可以指以下三种情况：与RS0对应的波束(链路)故障、与RS1对应的波束(链路)故障、以及与RS0对应的波束和与RS1对应的波束(链路)两者均故障。
作为示例，下行信号所表征的信道质量可以是基站与电子设备100之间的、利用与该下行信号对应的波束进行通信的链路的信道质量。例如，由电子设备100来估算该信道质量。
作为示例，可以利用误块率(BLER)来表征信道质量。本领域技术人员可以理解，当使用BLER表征信道质量时，下行信号所表征的信道质量低于候选下行信号所表征的信道质量指的是利用与该下行信号对应的波束进行通信的链路的BLER高于利用与候选下行信号对应的波束进行通信的链路的BLER。
作为示例，可以利用L1-RSRP(物理层的参考信号接收强度)来表征信道质量。本领域技术人员可以理解，当使用L1-RSRP表征信道质量时，下行信号所表征的信道质量低于候选下行信号所表征的信道质量指的是利用与该下行信号对应的波束进行通信的链路的L1-RSRP低于利用与候选下行信号对应的波束进行通信的链路的L1-RSRP。
作为示例，可以利用L1-SINR(物理层的信干噪比)来表征信道质量。本领域技术人员可以理解，当使用L1-SINR表征信道质量时，下行信号所表征的信道质量低于候选下行信号所表征的信道质量指的是利用与该下行信号对应的波束进行通信的链路的L1-SINR低于利用与候选下行信号对应的波束进行通信的链路的L1-SINR。
本领域技术人员还可以想到表征信道质量的其他方式，在此不再累述。
作为示例，电子设备100可以根据应用场景动态地确定候选下行信号。作为示例，电子设备100可以基于从基站接收的预定信道质量指标来确定候选下行信号。例如，基站预先定义一个预定信道质量值，电子设备100通过测量得知基站与电子设备100之间的、通过某一波束进行通信的链路的信道质量高于该预定信道质量值时，电子设备100可以将 与该波束对应的下行信号确定为候选下行信号。本领域技术人员还可以想到确定候选下行信号的其他方式，在此不再累述。
作为示例，本领域技术人员可以根据经验或实际需要或应用场景等确定预定偏差值。作为示例，预定偏差值可以是候选下行信号所表征的信道质量的5％或10％等等。
作为示例，本领域技术人员可以根据经验或实际需要或应用场景等确定第一计数值。
在根据本公开的实施例中，因为电子设备100在判定下行信号中的任一下行信号所对应的波束出现故障时就发送波束故障恢复请求(波束失败恢复请求)、而不是在每个下行信号所对应的波束都出现故障时才发送波束故障恢复请求，因此，可以将本公开的实施例中的波束故障恢复(波束失败恢复，BFR)称为部分波束故障恢复(部分波束失败恢复)。
作为示例，下行信号所表征的信道质量以预定偏差值低于由候选下行信号所表征的信道质量为层1(物理层)的与部分波束故障恢复相关的事件。
作为示例，在任一下行信号(例如，RS0和RS1中的任一信号)所表征的信道质量以预定偏差值低于由候选下行信号所表征的信道质量时，电子设备100的物理层给MAC(媒体接入控制)层发送一个BFI(波束失败实例)，并将MAC层所保留的与该任一下行信号对应的计数器的计数值加1，当收到来自物理层的与该一个下行信号对应的BFI积累达到第一计数值后，MAC层发送BFR请求，即，电子设备100向基站发送波束故障恢复请求，以对故障波束进行恢复。
图2A和2B示出了现有技术中的波束故障恢复的处理示例。在图2A中，当电子设备检测到q0中的仅仅由RS0所表征的信道质量低于预定门限值并且低于预定门限值的次数累积达到预定次数时，电子设备的物理层并不会向MAC层通知BFI。在图2B中，仅有当RS0和RS1所表征的信道质量都低于预定门限值时，电子设备的物理层才会向MAC层通知BFI，并且使得MAC层所保留的计数器的计数值加1，以及在计数值达到预定计数值时，向基站发送BFR请求。即，在现有技术中，当例如仅有一个下行参考信号(例如，RS0)对应的波束处于波束故障的状态下，电子设备不能进行波束故障恢复。
然而，根据本公开实施例的电子设备100能够在与基站之间的部分链路出现波束故障时(例如，利用与RS0对应的波束进行通信的链路和利用与RS1对应的波束进行通信的链路中的任一链路出现故障时)，提前进行部分波束故障恢复，使得全部链路失败的可能性被大大降低，从而能够有效地提升通信质量。此外，电子设备100能够基于其自身确定的候选下行信号来判定波束是否故障，因此，使得电子设备100具有一定的自主性。
作为示例，第一判定单元104可以被配置为通过在时间上紧挨判定故障波束之后的上行控制信道的时机来发送波束故障恢复请求，即在判定波束故障之后出现的第一个上行控制信道的时机发送波束故障恢复请求。其中，波束故障恢复请求包括表征故障波束的ID的信息。
作为示例，第一判定单元104可以被配置为在电子设备100具有下行波束和上行波束的对称性并且上述上行控制信道对应于故障波束时，放弃在时间上紧挨判定故障波束之后的上行控制信道的时机发送波束故障恢复请求，而是在下一上行控制信道的时机发送波束故障恢复请求。
作为示例，上行控制信道可以是物理上行控制信道PUCCH。
例如，当电子设备100具有下行波束(即，下行接收波束)和上行波束(即，上行发送波束)的对称性并且在时间上紧挨判定故障波束之后的PUCCH机会被配置的PUCCH-SpatialRelationInfo(空间关系信息)使用的上行发送波束正好是下行接收失败的波束(即，故障波束)时，电子设备100放弃在该次PUCCH中发送波束故障恢复请求，并使用下一次PUCCH的时机发送波束故障恢复请求，这样可以防止使用在时间上紧挨判定故障波束之后的PUCCH导致波束故障恢复请求传输失败。例如，下行波束和上行波束的对称性指的是电子设备100利用下行接收波束作为上行发送波束，来进行上行传输。
作为示例，第一判定单元104可以被配置为将下行信号的ID与PUCCH中的调度请求(Scheduling Request,SR)资源的ID相关联，以通过调度请求资源的ID表征与任一下行信号对应的故障波束的ID。通过该方式，电子设备100能够利用PUCCH向基站发送有关故障波束的ID的信息。
例如，下行信号的ID可以包括RS0的ID和RS1的ID。
例如，如果通过RRC(无线资源控制)配置将RS0的ID和RS1的ID与SR资源0和SR资源1相关联，那么电子设备100可以根据与故障波束对应的BFD RS(RS0或RS1)选择SR资源0或1，从而通过SR资源的ID表征故障波束的ID。
在NR系统中，目前定义的PUCCH format包括format 0、format 1、format 2、format 3以及format 4。其中format 0是根据生成PUCCH的循环移位的序列来承载信息，所以能承载的信息比较少，但是比较小巧灵活。format1可以通过一定的有效载荷来承载少量的信息。
作为示例，第一判定单元104可以被配置为通过设定PUCCH format 0中的预定循环移位序列的参数来表征故障波束的ID。通过该方式，电子设备100能够利用PUCCH向基站发送有关故障波束的ID的信息。
例如，电子设备100可以通过设置PUCCH format 0的循环移位序列的参数M_CS来表征故障波束的ID。例如，通过设置M_CS为第一值代表与RS0对应的波束出现故障，设置M_CS为第二值代表与RS1对应的波束出现故障，其中，第一值不同于第二值。
作为示例，第一判定单元104可以被配置为通过在PUCCH format 1中使用预定信息位来表征故障波束的ID。通过该方式，电子设备100能够利用PUCCH向基站发送有关故障波束的ID的信息。
例如，电子设备100可以通过在PUCCH format 1中的预定信息位b(x)来表征故障波束的ID，例如，令b(x)＝0代表与RS0对应的波束出现故障，以及令b(x)＝1代表与RS1对应的波束出现故障。
需要说明的是，尽管上文中描述了电子设备100可以利用PUCCH将有关故障波束的ID的信息发送给基站的情况，然而，电子设备100可以仅利用PUCCH将指示出现了波束故障的波束故障恢复请求(该波束故障恢复请求不包括有关故障波束的ID的信息，即该波束故障恢复请求没有明确指示哪个波束出现故障)发送给基站，即，电子设备100不利用PUCCH将有关故障波束的ID的信息发送给基站。在电子设备100不利用PUCCH将有关故障波束的ID的信息发送给基站的情况下，电子设备100可以利用MAC CE(媒体接入控制控制元素)将有关故障波束的ID的信息发送给基站。
作为示例，第一判定单元104可以被配置为还将关于候选下行信号的 信息发送给基站，并且使用候选下行信号所对应的波束替代故障波束。
作为示例，第一判定单元104可以被配置为利用MAC CE将关于候选下行信号的信息发送给基站。
由于候选下行信号是由电子设备100所选择确定的，因此，使得电子设备100可以不使用由基站指定的波束、而是主动启用候选下行信号所对应的波束来替代故障波束。
作为示例，第一判定单元104可以被配置为经由下行控制信道接收到基站确认对关于候选下行信号的信息的正确解码之后，使用候选下行信号所对应的波束替代故障波束。
作为示例，下行控制信道例如为PDCCH(物理下行控制信道)。
图3是示出根据本公开实施例的部分波束故障恢复处理的示例的图。图3示出了与集合q0中包括的RS0和RS1分别对应的波束(分别用RS0和RS1标记)、以及与候选下行信号RS2对应的波束(用RS2标记)，为了方便，下面以与RS0对应的波束为故障波束为例进行描述。与RS0对应的计数器的计数值初始为0，并且假设预定偏差值是RS2所表征的信道质量的5％。每当RS0所表征的信道质量以预定偏差值低于RS2所表征的信道质量时，将与RS0对应的上述计数值加上1(图3中的(1)和(2))。在RS0所表征的信道质量以预定偏差值低于RS2所表征的信道质量的次数达到第一计数值(例如，第一计数值为3)时，电子设备100判定与RS0对应的波束为故障波束(图3中的(3))，并且通过PUCCH向基站发送波束故障恢复请求(图3中的(4))。在基站从电子设备100接收到波束故障恢复请求之后，基站通过PDCCH调度PUSCH(物理上行共享信道)(图3中的(5))，电子设备100可以通过该PUSCH承载MAC CE以向基站传输关于候选下行信号的信息(在电子设备100仅利用PUCCH将指示出现了波束故障的波束故障恢复请求发送给基站，而没有利用PUCCH将有关故障波束的ID的信息发送给基站的情况下，MAC CE还可以包括有关故障波束的ID的信息)(图3中的(6))。当基站接收到该MAC CE后，基站经由PDCCH向电子设备100发送对该MAC CE正确解码的确认，该PDCCH应该使用与调度上述PUSCH相同的HARQ(混合自动重传请求)处理ID并且反转NDI(New data indicator，新数据指示符)这个信息位(图3中的(7))。当电子设备100经由PDCCH 收到基站确认对该MAC CE的正确解码后，知道与故障波束对应的下行信号(例如，RS0)或者该下行信号对应的CORESET启用了所上报的候选下行信号(RS2)对应的波束，从而使用候选下行信号所对应的波束替代故障波束(图3中的(8))。
与RS1对应的波束(链路)故障、以及与RS0对应的波束和与RS1对应的波束(链路)两者均故障时的部分波束故障恢复处理可以参照图3的部分波束故障恢复处理，这里不再累述。
根据本公开的另一个方面，还提供了一种用于无线通信的电子设备。
图4示出了根据本公开的另一个实施例的用于无线通信的电子设备400的功能模块框图，如图4所示，电子设备400包括：第二接收单元402，其可以被配置为从为电子设备400提供服务的基站接收用于监测波束是否故障的下行信号，以及第二判定单元404，其可以被配置为在满足(1)下行信号中的任一下行信号所表征的信道质量低于第一阈值的次数达到第二计数值和(2)如果在信道质量低于第一阈值的次数达到第二计数值之前、信道质量低于第二阈值的次数达到第三计数值中的任一个条件时，判定与该任一下行信号对应的波束为故障波束，并且向基站发送波束故障恢复请求，以对故障波束进行恢复，其中，第二阈值低于第一阈值，并且第三计数值小于第二计数值。
其中，第二接收单元402和第二判定单元404可以由一个或多个处理电路实现，该处理电路例如可以实现为芯片。
电子设备400例如可以设置在UE侧或者可通信地连接到UE。这里，还应指出，电子设备400可以以芯片级来实现，或者也可以以设备级来实现。例如，电子设备400可以工作为用户设备本身，并且还可以包括诸如存储器、收发器(图中未示出)等外部设备。存储器可以用于存储用户设备实现各种功能需要执行的程序和相关数据信息。收发器可以包括一个或多个通信接口以支持与不同设备(例如，基站、其他用户设备等等)间的通信，这里不具体限制收发器的实现形式。
有关用于监测波束是否故障的下行信号、任一下行信号等可参见关于电子设备100中相应部分的描述。在下文中，还以RS0和RS1为例来表示用于监测波束是否故障的下行信号。
作为示例，可以利用误块率(BLER)来表征信道质量。本领域技术 人员可以理解，当使用BLER表征信道质量时，下行信号所表征的信道质量低于预定阈值(第一阈值或第二阈值)指的是利用与该下行信号对应的波束进行通信的链路的BLER高于预定阈值。
作为示例，可以利用L1-RSRP(物理层的参考信号接收强度)来表征信道质量。本领域技术人员可以理解，当使用L1-RSRP表征信道质量时，下行信号所表征的信道质量低于预定阈值指的是利用与该下行信号对应的波束进行通信的链路的L1-RSRP低于预定阈值。
作为示例，可以利用L1-SINR(物理层的信干噪比)来表征信道质量。本领域技术人员可以理解，当使用L1-SINR表征信道质量时，下行信号所表征的信道质量低于预定阈值指的是利用与该下行信号对应的波束进行通信的链路的L1-SINR低于预定阈值。
本领域技术人员还可以想到表征信道质量的其他方式，在此不再累述。
作为示例，本领域技术人员可以根据经验或实际需要或应用场景等确定第一阈值、第二计数值、第二阈值、第三计数值。
在电子设备400中，除了设置条件(1)下行信号中的任一下行信号所表征的信道质量低于第一阈值的次数达到第二计数值之外，还设置了条件(2)如果在信道质量低于第一阈值的次数达到第二计数值之前、信道质量低于第二阈值的次数达到第三计数值，并且，第二阈值低于第一阈值，以及第三计数值小于第二计数值。设置条件(2)可以满足VIP用户对于通信链路的较高通信质量的需求。
在根据本公开的实施例的电子设备400中，因为电子设备400在判定满足条件(1)和(2)中的任一个条件时(即，下行信号中的任一下行信号所对应的波束出现故障时)就发送波束故障恢复请求、而不是在每个下行信号所对应的波束都出现故障时才发送波束故障恢复请求，因此，电子设备400所涉及的波束故障恢复为部分波束故障恢复。
作为示例，下行信号所表征的信道质量低于预定阈值(第一阈值或第二阈值)为层1(物理层)的与部分波束故障恢复相关的事件。
下文中还以任一下行信号为RS0为例来进行描述。在RS0所表征的信道质量低于第一阈值时，电子设备400的物理层给MAC层发送一个 BFI，并将MAC层所保留的与第一阈值对应的第一计数器的计数值加1，以及在RS0所表征的信道质量低于第二阈值时，电子设备400的物理层给MAC层发送一个BFI，并将MAC层所保留的与第二阈值对应的第二计数器的计数值加1；电子设备400在判定满足条件(1)和(2)中的任一个条件时，MAC层发送BFR请求，即，电子设备400向基站发送波束故障恢复请求，以对故障波束进行恢复。
根据本公开实施例的电子设备400能够在与基站之间的部分链路出现波束故障时(例如，利用与RS0对应的波束进行通信的链路和利用与RS1对应的波束进行通信的链路中的任一链路出现故障时)，提前进行部分波束故障恢复，使得全部链路失败的可能性被大大降低，从而能够有效地提升通信质量；并且通过设置条件(2)能够满足VIP用户对于通信链路的较高通信质量的需求。
作为示例，第二判定单元404可以被配置为通过在时间上紧挨判定故障波束之后的上行控制信道的时机来发送波束故障恢复请求，即在判定波束故障之后出现的第一个上行控制信道的时机发送波束故障恢复请求，并且波束故障恢复请求包括有关故障波束的ID的信息。
作为示例，第二判定单元404可以被配置为在电子设备400具有下行波束和上行波束的对称性并且上述上行控制信道对应于故障波束时，放弃在时间上紧挨判定故障波束之后的上行控制信道的时机发送波束故障恢复请求，而是在下一上行控制信道的时机发送波束故障恢复请求。
作为示例，上行控制信道可以是物理上行控制信道PUCCH。
例如，当电子设备400具有下行波束(即，下行接收波束)和上行波束(即，上行发送波束)的对称性并且在时间上紧挨判定故障波束之后的PUCCH机会被配置的PUCCH-SpatialRelationInfo使用的上行发送波束正好是下行接收失败的波束(即，故障波束)时，电子设备400放弃在该次PUCCH中发送波束故障恢复请求，并使用下一次PUCCH的时机发送波束故障恢复请求，这样可以防止使用在时间上紧挨判定故障波束之后的PUCCH导致波束故障恢复请求传输失败。例如，下行波束和上行波束的对称性指的是电子设备400利用下行接收波束作为上行发送波束，来进行上行传输。
作为示例，第二判定单元404可以被配置为将下行信号的ID与 PUCCH中的调度请求资源的ID相关联，以通过调度请求资源的ID表征与任一下行信号对应的故障波束的ID。通过该方式，电子设备400能够利用PUCCH向基站发送有关故障波束的ID的信息。
例如，下行信号的ID可以包括RS0的ID和RS1的ID。
例如，如果通过RRC(无线资源控制)配置将RS0的ID和RS1的ID与SR资源0和SR资源1相关联，那么电子设备400可以根据与故障波束对应的BFD RS(RS0或RS1)选择SR资源0或1，从而通过SR资源的ID表征故障波束的ID。
作为示例，第二判定单元404可以被配置为通过设定PUCCH format 0中的预定循环移位序列的参数来表征故障波束的ID。通过该方式，电子设备400能够利用PUCCH向基站发送有关故障波束的ID的信息。
例如，电子设备400可以通过设置PUCCH format 0的循环移位序列的参数M_CS来表征故障波束的ID。例如，通过设置M_CS为第一值代表与RS0对应的波束出现故障，设置M_CS为第二值代表与RS1对应的波束出现故障，其中，第一值不同于第二值。
作为示例，第二判定单元404可以被配置为通过在PUCCH format 1中使用预定信息位来表征故障波束的ID。通过该方式，电子设备400能够利用PUCCH向基站发送有关故障波束的ID的信息。
例如，电子设备400可以通过在PUCCH format 1中的预定信息位b(x)来表征故障波束的ID，例如，令b(x)＝0代表与RS0对应的波束出现故障，以及令b(x)＝1代表与RS1对应的波束出现故障。
作为示例，电子设备400可以使用由基站指定的新波束替代故障波束来进行通信。作为示例，第二判定单元404可以被配置为基于与基站通过MAC CE更新的信息所对应的波束，替代故障波束。
作为示例，当基站收到来自电子设备400的波束故障恢复请求后，基站可以通过PDCCH调度PDSCH(物理下行共享信道)，并可以在PDSCH中承载MAC CE，该MAC CE更新与电子设备400上报的BFD RS所对应的CORESET的TCI(传输配置指标)状态，即更新与该CORESET对应的波束信息，从而去激活与所上报的BFD RS对应的故障波束，并为该CORESET启用新的波束。
当电子设备400收到该MAC CE后，电子设备400向基站发送承载该MAC CE的PDSCH的HARQ-ACK信息，并且在预定的时间(例如，3ms)时间后认为该更新的CORESET波束生效，并将第一计数器和第二计数器的计数值重置为零。
图5是示出根据本公开另一实施例的部分波束故障恢复处理的示例的图。图5示出了与集合q0中包括的RS0和RS1分别对应的波束(分别用RS0和RS1标记)，与RS0对应的第一计数器和第二计数器的计数值初始均为零。图5中以任一下行信号为RS0为例来进行描述。在RS0所表征的信道质量低于第一阈值时，将与第一阈值对应的第一计数器的计数值加1，以及在RS0所表征的信道质量低于第二阈值时，将与第二阈值对应的第二计数器的计数值加1(图5中的(1))；电子设备400在判定满足前述条件(1)和(2)中的任一个条件(图5中的(2)，在图5的(2)中，将条件(1)和(2)简写为条件1和2)时，通过PUCCH向基站发送波束故障恢复请求(图5中的(3))。当基站收到来自电子设备400的波束故障恢复请求后，基站可以通过PDCCH调度PDSCH(图5中的(4))，并可以在PDSCH中承载MAC CE，该MAC CE更新与电子设备400上报的RS0所对应的CORESET的TCI状态(图5中的(5))，从而去激活与所上报的RS0对应的故障波束，并为该CORESET启用新的波束。
与RS1对应的波束(链路)故障、以及与RS0对应的波束和与RS1对应的波束(链路)两者均故障时的部分波束故障恢复处理可以参照图5的部分波束故障恢复处理，这里不再累述。
根据本公开的另一个方面，还提供了一种用于无线通信的电子设备。
