波束失败检测的方法、装置及终端
交叉引用
本发明要求在2021年09月26日提交中国专利局、申请号为202111131971.6、发明名称为“波束失败检测的方法、装置及终端”的中国专利申请的优先权，该申请的全部内容通过引用结合在本发明中。
技术领域
本申请属于通信技术领域，具体涉及一种波束失败检测的方法、装置及终端。
背景技术
在5G通信系统中，终端(User Equipment，UE，也可以称作终端设备或者用户设备)可通过周期性的测量参考信号来实现对物理下行控制信道(Physical downlink control channel，PDCCH)的通信质量的监测，并在发现该信道不能提供可靠通信时，宣布波束失败。
但是，考虑到B52.6频段的非授权频谱，可能由于网络侧先听后说(Listen-Before-Talk，LBT)失败没有成功接入信道，进而导致波束失败检测参考信号(Beaming Failure Detection Reference Signal，BFD RS)无法发送，终端若仍然基于前述波束检测机制进行波束失败检测，会默认其发生了波束失败事件，从而降低了波束失败检测的准确率。
发明内容

下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”所区别的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”一般表示前后关联对象是一种“或”的关系。
值得指出的是，本申请实施例所描述的技术不限于长期演进型(Long Term Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，还可用于其他无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)和其他系统。本申请实施例 中的术语“系统”和“网络”常被可互换地使用，所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。以下描述出于示例目的描述了新空口(New Radio，NR)系统，并且在以下大部分描述中使用NR术语，但是这些技术也可应用于NR系统应用以外的应用，如第6代(6 th Generation，6G)通信系统。
图1示出本申请实施例可应用的一种无线通信系统的结构示意图。无线通信系统包括终端11和网络侧设备12。其中终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant，PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer，UMPC)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备(VUE)、行人终端(PUE)等终端侧设备，可穿戴式设备包括：智能手表、手环、耳机、眼镜等。需要说明的是，在本申请实施例并不限定终端11的具体类型。网络侧设备12可以是基站或核心网，其中，基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、WLAN接入点、WiFi节点、发送接收点(Transmitting Receiving Point，TRP)或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本申请实施例中仅以NR系统中的基站为例，但是并不限定基站的具体类型。
下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的技术方案进行详细地说明。
如图2所示，为本申请一示例性实施例提供的波束失败检测的方法200的流程示意图，该方法200可以但不限于由终端执行，具体可由安装于终端中的硬件和/或软件执行。本实施例中，所述方法200至少可以包括如下步骤。
S210，终端根据第一计数器和/或第二计数器，确定发生或未发生BF事 件。
本实施例中，所述终端可在物理层对用于波束失败检测的目标参考信号进行测量，并基于测量结果判断是否发生波束失败事件，但考虑到非授权频段在使用时必须符合监管条例以保证所有设备可以公平地共享该资源，例如传输前侦听信道(Listen Before Talk，LBT)、最大信道占用时间(Maximum Channel Occupancy Time，MCOT)等。在此以LBT为例，当网络侧(如基站等)需要发送目标参考信号等信息时，需先在指定无线信道上执行LBT，以对周围的无线传输环境进行能量检测(Energy Detection，ED)，当能量高于一定门限时，则判断传输信道为忙，网络侧不能进行发送。在此情况下，终端基于目标参考信号测量到的信道质量必然不满足传输需求，也就是终端会判定前述的指定无线信道不能提供可靠通信，进而宣布波束失败。但是此时实际并未发生波束失败。对此，本申请通过引入第一计数器，并根据第一计数器和/或第二计数器实现对波束失败的判断，可以提高波束失败检测的准确率。
基于此，在本实施例中，所述第一计数器与第一阈值对应，所述第一阈值为LBT失败对应的阈值。可选的，所述第一计数器为本申请新引入的计数器，用于实现对LBT失败次数的计数，在此情况下，所述第一计数器可以设置于物理层或媒体接入控制(Medium Access Control，MAC)层，也就是说，所述第一计数器可以是物理层计数器或MAC层计数器。
所述第二计数器与第二阈值对应，所述第二阈值为波束接收失败对应的阈值；也就是说，所述第二计数器用于对波束失败实例(beam failure instance，BFI，也可以理解为波束失败信息或波束失败指示等)进行计数，以使得终端基于第二计数器进行波束失败事件的判断。
一种实现方式中，所述第一阈值可以大于所述第二阈值，由此可以使得所述终端在基于所述第一阈值和所述第二阈值进行所述第一计数器和/或所述第二计数器计数时，提高计数结果的准确性，进而更加准确的区分波束失 败和LBT失败。
可以理解，所述第一计数器、所述第一阈值、所述第二计数器、所述第二阈值可以由协议约定、高层配置或网络侧配置实现，在此不做限制。
本实施例中，终端根据第一计数器和/或第二计数器，确定发生或未发生BF事件，由此，能够有效避免由于存在LBT失败而导致的BFI误增加的问题，进而提高波束失败检测的准确率。
如图3所示，为本申请一示例性实施例提供的波束失败检测的方法300的流程示意图，该方法300可以但不限于由终端执行，具体可由安装于终端中的硬件和/或软件执行。本实施例中，所述方法300至少可以包括如下步骤。
S310，终端根据第一计数器和/或第二计数器，确定发生或未发生BF事件。
其中，所述第一计数器与第一阈值对应，所述第一阈值为LBT失败对应的阈值；所述第二计数器与第二阈值对应，所述第二阈值为波束接收失败对应的阈值。
可以理解，S310的实现过了除了可参照方法实施例200中的相关描述之外，作为一种可能的实现方式，所述终端根据第一计数器和/或第二计数器，确定发生或未发生BF事件的方式可以包括以下(11)-(13)中的至少一项。
(11)在所述第一计数器的计数值不小于第一预定值的情况下，确定发生所述BF事件。也就是说，在所述第一计数器的计数值达到第一预定值时，所述终端可默认波束失败，以及开始波束失败恢复的流程。
例如，假设所述第一计数器的计数值为A、第一预定值为a，那么，如果A>＝a，可确定发生所述BF事件。
可选的，所述第一计数器的计数过程包括：所述终端在检测到的目标参考信号的误块率(Block Error Rate，BLER)大于所述第一阈值的情况下，所述第一计数器的计数值增加，例如所述第一计数器加1。
其中，所述第一计数器为MAC层计数器或物理层计数器。也就是说， 在所述第一计数器为MAC计数器或物理层计数器、且检测到的目标参考信号的BLER大于所述第一阈值的情况下，所述第一计数器的计数值均增加。
另外，所述目标参考信号可以包括但不限于信道状态信息-参考信号(Channel State Information Reference Signal，CSI-RS)、同步信号块(Synchronization Signal and PBCH block，SSB)或者其他的BFD-RS等，在此不做限制。
可选地，所述终端在检测到的目标参考信号的BLER大于所述第一阈值的情况下，所述终端上报LBT失败指示给所述终端的MAC层。
一种实现方式中，所述终端可在检测到目标参考信号的BLER大于所述第一阈值的情况下，所述终端判定LBT失败，上报LBT失败指示给所述终端的MAC层，以及将所述第一计数器的计数值增加。
(12)在所述第一计数器的计数值与所述第二计数器的计数值之和不小于第二预定值的情况下，确定发生所述BF事件，以及可开始波束失败恢复的流程。
例如，假设所述第一计数器的计数值为A、第二计数器的计数值为B、第二预定值为C，那么，如果A+B>＝C，可确定发生所述BF事件。
在此情况下，所述第一计数器的计数器可参照(11)中的相关描述。
所述第二计数器的计数过程可以包括以下(121)-(123)中的至少一项。
(121)在检测到的目标参考信号的BLER不大于所述第一阈值但大于所述第二阈值的情况下，所述第二计数器的计数值增加，例如，所述第二计数器的计数值加1。
(122)在所述第一计数器为MAC层计数器、且所述第一计数器的计数值达到第五预定值的情况下，所述第二计数器的计数值增加。
(123)在所述第一计数器为物理层计数器、且所述第一计数器的计数值不小于所述第五预定值的情况下，所述第二计数器的计数值增加。
(13)在所述第一计数器的计数值不小于第三预定值和/或所述第二计数 器的计数值不小于第四预定值的情况下，确定发生所述BF事件，以及可开始波束失败恢复的流程。
例如，假设所述第一计数器的计数值为A、第二计数器的计数值为B、第三预定值为a、第四预定值为b，那么，如果A>＝a，可确定发生所述BF事件，或者，如果B>＝b，可确定发生所述BF事件；或者，如果A>＝a、且B>＝b，可确定发生所述BF事件。
需要注意，本申请中提及的第一预定值、第二预定值、第三预定值、第四预定值、第五预定值等均可以由协议约定、高层配置或网络侧配置实现。此外，第一预定值、第二预定值、第三预定值、第四预定值、第五预定值可以相同也可以不同，在此不做限制。
当然，作为一种可能的实现方式，所述终端在确定发生BF事件的情况下，上报波束失败实例BFI给MAC层，和/或，重置所述第一计数器。
例如，当所述第一计数器为物理层计数器、且确定发生BF事件的情况下，上报BFI给MAC层，以及重置所述第一计数器。
又例如，当所述第一计数器为MAC层计数器、且确定发生BF事件的情况下，可取消上报BFI给MAC层，但需重置所述第一计数器。
S320，执行预定操作。
其中，所述预定操作包括以下(21)-(24)中的至少一项。
(21)所述终端的MAC层在接收到LBT失败指示的情况下，重置所述第一计数器。
(22)所述终端在所述第一计数器超时的情况下，重置所述第一计数器。
(23)所述终端的MAC层在接收到BFI的情况下，重置所述第二计数器。
(24)所述终端在所述第二计数器超时的情况下，重置所述第二计数器。
对于前述(21)-(24)可以理解的是，所述第一计数器和所述第二计数器之间可以为相互独立的计数器，也可以为相同的计数器，本实施例对此不 做限制。
另外，本实施例中提及的“重置”也可以理解为重启、复位、重新计数等，在此不做限制。
基于前述对波束失败检测的方法200/或300的描述，下面进一步结合如下示例对本实施例给出的波束失败检测过程进行说明，内容如下。
终端在物理层对用于波束失败检测的目标参考信号进行测量，并根据对目标参考信号的测量结果，以及第一计数器和/或第二计数器，来判断是否发生波束失败事件。其中，所述第一计数器与第一阈值对应、且所述第一阈值为与LBT失败对应的阈值，所述第二计数器与第二阈值对应、且所述第二阈值为波束接收失败对应的阈值。
基于此，如果所述终端在物理层测量的目标参考信号的BLER大于第一阈值，可判定由于LBT失败(也就是在原本应该发送目标参考信号的位置，由于监听到信道繁忙，网络侧没有发送该目标参考信号，导致所述终端测量的目标参考信号的BLER大于第一阈值)。
此时，所述终端可以开始或者重置所述第一计数器的计数值。例如，当第一计数器在MAC层为计MAC层计数器，所述终端可以上报LBT指示给MAC层，且第一计数器的计数值加1；或，当所述第一计数器在物理层计数，则所述第一计数器的计数值加1；当LBTF_timer(基于LBT指示的计时器，与波束失败恢复定时器(beam Failure Recovery Timer)对应)超时或者重新配置后，则所述第一计数器重置为0。
又例如，如果所述第一计数器达到第五预定值时(所述第一计数器可以在物理层或者MAC层)，则默认为发生了一次BFI事件，且所述第二计数器(BFI_COUNTER)+1，当第二计数器达到一定值时，MAC层触发波束失败流程。
或者，如果所述第一计数器达到第一预定时，直接宣布波束失败，触发波束失败恢复的流程(一般是在MAC层宣布)，随后，该第一计数器重置为 0。
或者，所述终端可以联合所述第一计数器和第二计数器(BFI_COUNTER计数器)，判断是否波束失败，并触发波束失败恢复的流程。前述的联合判断，可以包括如下(41)-(43)中的至少一项。
(41)两个计数器之和相加大于等于某一定值(如A+B>＝C)。
(42)两者同时满足大于等于相对应的定值(A>＝a且(and)B>＝b)。
(43)两者之一满足大于等于相对应的定值(A>＝a或(or)B>＝b)。
最后，在确定发生波束失败的情况下，将所述第一计数器重置为0。
本实施例中，进一步给出了终端联合第一计数器、第二计数器进行波束失败确定的相关过程，能够进一步提高波束失败检测结果的可靠性。
