Since the goal of beam failure measurement is to know whether the downlink control channel can be correctly received by the terminal, the BLER value can achieve this goal well.
  • the configuration of the reference signal used for beam failure measurement can adopt an explicit configuration method in which the network informs the terminal through signaling, or the terminal implicitly configures it through a beam configuration method through control signaling, as follows:

Therefore, the beam quality may also continuously jump around the threshold. In order to avoid the ping-pong effect and frequent beam failure events, only when the beam measurement result is lower than the set threshold for a long enough time can the beam failure event be considered as occurring. It is possible to determine whether a beam failure event occurs by counting the number of times that the beam measurement is lower than the threshold.

场景3，Pcell在FR1(不需要BFR的频段)，Scell上只能进行下行链路DL的传输(DL-only Scell)；
场景4，Pcell在FR2(需要进行BFR的频段)，Scell上只能进行下行链路DL的传输(DL-only Scell)。
现有的Rel-15 NR系统的BFR机制在应用到Scell的时候只适用于场景1和场景2，不适用于场景2和场景3。
如果使用物理上行链路控制信道(Physical Uplink Control Channel，PUCCH)进行Scell BFR过程中的上报承载信道，则一种可能的方式是UE在Pcell上进行波束失败事件和候选波束的上报，在Pcell或Scell接收基站的波束失败恢复响应，但这种方式在场景2和场景4下的性能无法得到保障，因为Pcell自身可能也发生了波束失败。

随着低频段资源的变得稀缺，而毫米波频段具有更多的频谱资源，能够提供更大带宽， 成为了移动通信系统未来应用的重要频段。毫米波频段由于波长较短，具有与传统低频段频谱不同的传播特性，例如更高传播损耗，反射和衍射性能差等。因此通常会采用更大规模的天线阵列，以形成增益更大的赋形波束，克服传播损耗、确保系统覆盖。对于毫米波天线阵列，由于波长更短，天线阵子间距以及孔径更小，可以让更多的物理天线阵子集成在一个有限大小的二维天线阵列中；同时，由于毫米波天线阵列的尺寸有限，从硬件复杂度、成本开销以及功耗等因素考虑，无法采用低频段所采用的数字波束赋形方式，而是通常采用模拟波束与有限数字端口相结合的混合波束赋形方式。如图1所示的混合波束赋形收发架构图，设发送端有N T根天线，接收端有N R根天线，每根有单独的射频通道，而只有K条数字通道，且K远远小于N T和N R。
对于一个多天线阵列，其每根天线都有独立的射频链路通道，但共享同一个数字链路通道，每条射频链路允许对所传输信号进行独立的幅度和相位调整，所形成的波束主要通过在射频通道的相位和幅度调整来实现，称为模拟波束赋形信号。而全数字波束赋形的天线阵列的每根天线都有独立的数字链路通道，可以在基带控制每路信号的幅度和相位。
模拟波束赋形具有以下特点：
每根天线发送的信号一般通过移相器改变其相位；
由于器件能力的限制，模拟波束赋形都是整个带宽上进行赋形，无法像数字波束赋形针对部分子带单独进行赋形，因此，模拟波束赋形间通过时分复用(Testing Data Management，TDM)方式进行复用。
由于上述特点，模拟波束赋形的赋形灵活性方面要低于数字波束赋形，但模拟波束赋形的天线阵列所需要的数字链路要远低于数字波束赋形的天线阵列，因此在天线数量变得很大的情况下，模拟波束的天线阵列成本下降明显。
混合波束赋形结构在数字波束赋形灵活性和模拟波束赋形的低复杂度间做了平衡，具有支撑多个数据流和多个用户同时赋形的能力。同时，复杂度也控制在合理范围，因此成为毫米波传输的一种广泛采用方式，并成为5G NR系统最重要的传输方式。
对于采用高频段传输的系统，其物理下行控制信道(Physical Downlink Control Channel，PDCCH)可以采用模拟波束赋形传输来实现更高赋形增益和更大覆盖。用于下行控制PDCCH信道的无线资源被半静态分成多个控制资源集合(Control Resource SET，CORESET)，每个CORESET包含多个PDCCH信道的无线资源。基站可为每个CORESET半静态匹配一个发送波束方向，不同CORESET匹配不同方向波束。基站可以在不同CORESET中进行动态切换，从而实现波束的动态切换。当发送PDCCH的时候，基站可根据终端的信息，选择合适波束方向的CORESET。在接收端，终端在所配置的多个CORESET内进行盲检。对于每个候选的CORESET，终端将使用与CORESET发送波束对应的接收波束进行接收。
对于高频段的模拟波束赋形面临的一个重要挑战是传输信号的传播损耗大、被遮挡概率高。对于被遮挡的下行控制信道PDCCH，终端将无法准确获得下行传输的控制信息，从而接收性能下降，如速率下降、调度时延增加、用户体验下降等。一种可降低遮挡概率的方法是为CORESET配置多个方向的波束，可以使得PDCCH信道通过多个方向发送，避免在某个方向受到遮挡而导致链路不可靠的问题。然而采用这种方法带来新的问题是：由于终端对于PDCCH信道的盲检能力受限，使得配置给终端每个方向的CORESET数量会减少。例如在NR标准(Rel-15)中限制了每个终端在同一个激活的带宽部分(Bandwidth Part，BWP)中最多配置3个CORESET。理论上讲，如果发送波束角度扩展足够宽，能够覆盖整个小区覆盖角度区域，这样就不会出现波束遮挡的问题了。但为了获得更高的波束赋形增益，通常波束的覆盖角度较小，波束较窄。考虑到有限的CORESET数量以及窄波束特点，在高频段毫米波通信中，控制信道的角度覆盖范围有限，容易造成控制信道的覆盖空洞，无法保证控制信道可靠接收。
如果像LTE等通信系统似的，若为控制信道配置的下行波束都失败时，就认为无线链路失败，开启无线链路重建的过程，则除了增加时延外，还有可能会造成资源的浪费，因为换个发送波束和/或接收波束就有可能使得下行控制信号的接收质量可以满足要求。为了避免这种资源浪费和时延，在NR标准中，一种快速、可靠的波束失败检测和恢复过程被标准化，使得网络侧能够快速从波束失败中恢复传输过程，即波束失败恢复(Beam Failure Recovery，BFR)机制，具体的BFR机制参见以下实施例。
实施例一，波束失败恢复(BFR)机制的波束失败监测过程。
由于基站可通过多个下行控制信道波束发送PDCCH，因此下行波束失败被定义为：终端接收到的每一个下行控制信道波束的质量都低于规定阈值，使得终端无法有效地接收到PDCCH信道所发送的控制信息。
不失一般性，假设基站有M个波束用于下行控制信道发送，为每个波束配置专属的参考信号，终端通过测量M个波束的参考信号来判断下行控制信道是否满足接收质量要求。如果所有的M个波束的信道质量都低于所设立的阈值，终端将认为波束失败事件发生。
NR系统中波束失败的监测指标参数为误块率(Block Error Rate，BLER)，具体过程如下：终端测量与下行控制信道相同波束的参考信号性能，并根据所测量到参考信号的信道质量，推断出PDCCH信道的译码错误概率BLER，具体地，UE测量参考信号的参考信号接收功率(Reference Signal Receiving Power，RSRP)，根据RSRP与PDCCH BLER的映射关系曲线，推断出PDCCH的BLER。如果BLER值高于所设定阈值(例如，BLER＝10％)，则认为该波束失败。当终端测量到所有M个波束的BLER值都高于阈值，则认为波束失败事件发生。在测量BLER的过程中，不需要对PDCCH信道进行解调译码，只是测量所对应参考信号的性能，并根据参考信号的结果推测PDCCH信道的BLER。由 于波束失败测量的目标在于获知下行控制信道能否被终端正确接收，因此BLER值可以很好地达到这个目的。
用于波束失败测量(检测)的参考信号的配置，可以采用网络通过信令通知终端的显式配置方式，或者终端通过控制信令的波束配置方法来隐含配置，具体如下：
显式配置方式，基站通过信令给终端配置一个用于测量波束质量的参考信号集合，包括参考信号类型：同步信号块(Synchronization Signal Block，SSB)、信道状态信息参考信号(Chanel State Information Reference signal，CSI-RS)，发送功率、参考信号的资源指示、参考信号资源等都需要清晰地通过网络配置给终端；
隐含指示方式，用于测量波束质量的参考信号集合可以从所对应的CORESET资源的传输配置指示(Transmission Confiuration Indication，TCI)状态中推导出来。具体而言，对于涉及模拟波束赋形传输的CORESET，其TCI状态中会包括一个参考信号的配置信息，并且该参考信号对应的准共址QCL(Quasi co-location)类型为QCL-TypeD。如果网络没有为终端显式配置用于波束失败检测的参考信号，则终端可以对CORESET所配置的TCI状态中的参考信号进行测量，以判断是否发生波束失败。
无线移动通信的一个本质特性在于发送端和接收端的无线信道具有快速起伏变化的特性。因此，波束质量也有可能在阈值附近不断跳变。为了避免乒乓效应和经常出现波束失败事件，只有当波束测量结果低于所设定阈值的时间足够长才能认为发生波束失败事件。可以通过统计波束测量低于阈值的次数来判断是否发生波束失败事件。具体而言，每次传输中对下行控制信道的参考信号进行测量，当测量结果低于阈值，将被计数一次失败，而高于阈值计数一次成功；只有当连续失败的次数大于预先设置的值，才判定波束失败事件发生。
实施例二，波束失败恢复(BFR)机制的波束失败与新候选波束上报过程。
当终端测量得到波束失败事件发送以后，终端需要将该事件上报给基站，并上报新的候选波束信息。基站收到上报信息后，通过波束恢复过程尽快从波束失败中恢复，重新选择用于传输的新波束替代原有波束。新波束将被用于基站对上报失败事件的应答信息传输，以及后续基站与终端间数据和控制信息的传输。
为了能够让终端上报新的候选波束，网络需要给终端配置相应的参考信号资源集合，这些参考信号对应了候选波束集。终端通过测量参考信号集合，确定用于传输链路的收发波束对。当终端完成测量后，把新候选波束上报给网络，所选择的新候选波束需要满足性能门限要求：RSRP超过阈值。在标准中，终端只将一个新候选波束上报给基站。如果测量过程中发现有多个波束质量达到阈值要求，终端可以根据自身判断，选择其中一个上报给基站，比如，将最强波束上报。
在波束失败测量和恢复过程中，为了不影响常规的随机接入过程，用于波束失败恢复 的信道为PRACH信道。PRACH信道是终端用于初始接入网络时的上行同步和信息交换信道。通过PRACH信道发送上行前导序列，网络可以实现对终端的确认，上行同步的测量，竞争解决等功能。在5G NR中，系统支持多个PRACH信道，每个PRACH信道与一个SSB(Synchronization Signal Block)对应(不同SSB用不同发送方向的波束进行广播信息发送)，终端所选择的PRACH信道对应着下行最合适的SSB波束发送方向。因此，当候选下行波束对应的参考信号与上行PRACH信道建立起一一对应关系，则意味着基站通过检测到的PRACH信道获得终端上报的候选波束信息。PRACH信道可以采用竞争的物理层信道或者非竞争的专用物理层信道。终端将会被分配专用随机接入信道资源与随机接入前导序列，每个随机接入信道和前导序列都与一个SSB传输块的波束方向对应。一旦发生下行波束失败事件和新的候选波束被选定，将通过该候选波束所对应的随机接入信道和前导序列进行发送。
另一种可以用于波束失败恢复的机制为使用PUCCH进行候选波束的上报。在5G NR标准中PUCCH信道用于上行控制信令的传输，PUCCH信道将各种类型的上行控制信令上报给网络，包括了应答信息(Acknowledgement/Negative ACKnowledgement，ACK/NACK)，调度请求，信道状态信息(CSI)和波束测量结果等。一个终端可以配置多个PUCCH信道资源，每个PUCCH信道资源对应不同的物理资源、发送功率、负载能力以及负载类型。PUCCH信道发送波束由网络进行配置。相比于PRACH信道，PUCCH信道体现出更好的上报能力和灵活性，多个候选的波束及波束质量等更多信息可以通过PUCCH信道上报给网络。但是由于PUCCH信道性能更容易在上行时间同步、波束方向精确性等方面受到影响，当下行波束失败，PUCCH在可靠性和鲁棒性方面性能将无法得到保证，因此在标准化过程中PUCCH不用于作为上报信道。
实施例三，波束失败恢复(BFR)机制的波束失败恢复响应。
如上述实施例所述，每个终端被分配多个CORESET用于PDCCH的传输，每个CORESET被配置一个波束发送方向。这些原有的CORESET所对应的波束在波束恢复过程中不会变更。网络将为终端配置一个专用的CORESET，称为CORESET_BFR，用于波束恢复的控制信令传输。当终端测量并上报波束失败消息后，终端开始监听CORESET_BFR的PDCCH信道，并假设所用波束为上报的新候选波束。对应于终端上报过程，基站将在CORESET_BFR中用新波束发送PDCCH信道。当终端检测到PDCCH信道，将认为上报的波束失败事件以及新候选波束被基站正确接收。
当基站接收到波束失败事件上报，并在CORESET_BFR中发送了响应消息后，如果终端未收到RRC重配置消息(用于原来的CORESET集合的波束配置)，则CORESET_BFR将作为另一个用于调度的CORESET进行正常通信；如果终端收到RRC重配置消息，终端将根据信息获得CORESET集合的新波束配置，并且停止对CORESET_BFR监听。
在波束恢复过程中，原有的CORESET仍然使用原来配置的波束，终端也对原有波束方向的PDCCH信道进行监听。虽然终端已经向基站上报了所有控制信道都处于波束失败状态，但这个判断是基于10％的BLER测量结果得到的，终端在原来的PDCCH信道仍然有可能接收到控制信令消息。因此，当基站接收到波束失败上报，并在CORESET_BFR中发送了响应消息，基站和终端还可以继续使用原来配置的CORESET集合和波束参数进行通信，并可对下行控制信道的波束进行重配置。

实施例五，目标小区Tcell的确定。
方式一，对于每一个Scell，都采用预定义的方式确定Tcell。这个Tcell可以为PCell或Scell。一些可能的预定Tcell的方式有：
协议约定所有Cell对应的TCell都是PCell；
协议约定所有Cell对应的TCell都是频点低于预设数值的(例如，预设数值为6GHz，此时对应于NR系统Rel-15标准里的FR1)的一个Cell；
协议约定一个频段(band)内的所有Cell对应的TCell相同，这个TCell为一个预定义的Cell。例如，如果存在PCell，这个TCell为PCell；如果不存在PCell，这个TCell为频率最低的SCell。
方式二，基站通过信令向UE指示Scell对应的TCell。这个信令可以是RRC信令，和/或MAC-CE信令，和/或DCI信令。例如，基站向UE发送的BFR信令中包含了TCell的指示信息；在PRACH-ResourceDedicatedBFR中增加了一个字段，这个字段用来指示用来发送SCell的波束失败上报的TCell；基站为UE的每个Cell配置一个PRACH-ResourceDedicatedBFR，PRACH-ResourceDedicatedBFR中增加两个字段，一个字段用来指示SCell的标识，一个字段用来指示发送Scell的波束失败上报的Tcell的标识；基站向UE发送的RRC信令BeamFailureRecoveryConfig中增加了两个字段，一个字段用来指示SCell的标识(字段1)，一个字段用来指示发送Scell的波束失败响应的Tcell的标识(字段2)，这两个字段具有一一对应的关系，即字段2指示的第n个Tcell为字段1指示的第n个Scell对应的发送Scell的波束失败响应的TCell，其中n大于等于1，小于等于字段1指示的Scell数。
方式三，BFR-RS(用于波束失败恢复的候选波束对应的参考信号)与TCell具有相关联关系。如果一个Scell对应一个BFR-RS，UE根据该BFR-RS与TCell的关联关系确定进行该Scell波束失败上报的TCell；如果一个Scell对应多个BFR-RS，UE根据待上报的候选波束对应的BFR-RS以及该BFR-RS与TCell的关联关系确定进行该Scell波束失败上报的TCell。可以在协议里为一个BFR-RS定义一个相关联的Cell，如果该BFR-RS为UE上报的用于波束失败恢复的候选参考信号，则UE在与之相关联的Cell上发送波束失败上报。优选地，BFR-RS与TCell的关联关系可以是基站通过信令指示给UE的，该信令优选地为RRC信令。次优的，BFR-RS与TCell的关联关系通过MAC-CE或DCI指示给UE。
在方式三下，TCell取决于UE选择的用于波束失败恢复的候选波束。TCell可以与BFR-RS所在的Cell是不同的Cell。例如，对于SCell 1，UE选择的BFR-RS为Scell 2上 的参考信号，但该BFR-RS对应的TCell为SCell 3，则UE在SCell 3上发送关于SCell 1的波束失败上报。
该方式比较灵活，基站可以根据各载波的负荷、频点、信道质量等情况，为每个BFR-RS选择较优的TCell。
方式四，TCell是UE选择的候选BFR-RS所在的Cell。如果一个Scell只对应一个BFR-RS，则TCell为BFR-RS所在的Cell；如果一个Scell对应多个BFR-RS，TCell为UE确定出的待上报的候选波束对应的BFR-RS所在的Cell。
方式四下，TCell取决于UE选择的用于波束失败恢复的候选波束。这种方法要求TCell为一个同时包含了UL和DL配置的Cell，即TCell既可以进行上行链路的传输，也可以进行下行链路的传输。
方式五，基站在为UE配置CORESET-BFR时配置了CORESET-BFR对应的发送波束失败响应的TCell。
具体实施时，可以采用上述方式一至五的融合方案。例如，对于一些SCell采用方式一，对于另外一些Scell采用方式二或者方式三。具体地，对于预定义了TCell的SCell采用预定义的方式确定TCell，对于没有预定义TCell的SCell采用方式二的确定方式；对于预定义了TCell的SCell采用预定义的方式确定TCell，对于没有预定义TCell的SCell采用方式三的确定方式。

综上所述，现有的NR系统的BFR机制只能在主小区PCell上进行，暂无辅小区Scell上的波束失败响应的发送接收机制。如果基站和UE对于发送各个Cell的波束失败响应的发送波束的理解不一致，将有可能导致UE无法正确地接收波束失败响应，从而影响波束失败恢复的过程。本申请提出了一种波束失败响应发送接收方法，使得基站与UE可以使用相同的假设进行波束失败响应的发送和接收，从而保证波束失败响应的性能。
因此，本申请实施例提供了一种小区上的BFR机制，以保证在各种场景下都能进行小区的波束失败恢复；
基于所述BFR机制，本申请提供了一种波束失败响应发送接收方法，使得基站与UE可以使用相同的假设进行波束失败响应的发送和接收，从而保证波束失败响应的性能。
