Abstract

提供了一种波束状态检测方法及终端。该波束状态检测方法，应用于终端，包括：对指示信息进行监控，指示信息由终端在未检测到用于进行波束失败检测的参考信号时生成；若监控到指示信息，根据指示信息进行波束状态检测。

Description

波束状态检测方法及终端
相关申请的交叉引用
本申请主张在2018年6月15日在中国提交的中国专利申请号No.201810623951.2的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，特别涉及一种波束状态检测方法及终端。
背景技术
用户设备(User Equipment，UE)(也称终端)的媒体接入控制(Medium Access Control，MAC)实体接收来自物理层的波束失败指示(beam failure instance indication)。MAC实体每次接收到该波束失败指示后，启动或重启动波束失败检测定时器(beam Failure Detection Timer)，并将波束失败检测计数器(BFI_COUNTER)进行累加。若波束失败检测定时器超时，波束失败计数器重置(如，设置为“0”值)。当波束失败计数器达到网络配置的门限值(如，beam Failure Instance Max Count)的时候，MAC实体认为发生了波束失败，从而触发波束失败恢复过程(如，通过触发随机接入过程进行波束恢复)。
对于非授权的频段，发送端在发送信号之前需要监听该频段是否被占用，如果没有被占用，则发送端可以进行信号的发送，网络侧在发送给UE的波束失败检测(Beam Failure Detection，BFD)测量用的参考信号(如，同步信号块(Synchronous Signal Block，SSB)和/或信道状态信息参考信号(Channel State Information–Reference Signal，CSI-RS))的时候，如果频点被占用了，则网络侧不会发送该参考信号。在BFD用的参考信号没有被发送的情况，终端测量得到的测量结果值会很差，而实际在发送BFD用的参考信号的情况，该测量结果值会好。上述情况会导致UE错误的将信道质量判断为差而指示“beam failure instance indication”，从而会导致错误判断该监测的波束出现问题。

具体实施方式
为使本公开的目的、技术方案和优点更加清楚，下面将结合附图及具体实施例对本公开进行详细描述。
本公开针对没有结合参考信号的实际发送情况进行信道质量的判断，易发生波束状态误判的问题，提供一种波束状态检测方法及终端。
如图1所示，本公开实施例提供的波束状态检测方法，应用于终端，包括：
步骤101，对指示信息进行监控；
其中，所述指示信息由终端在未检测到用于进行波束失败检测的参考信号时生成；本公开实施例中，引入在未检测到用于进行波束失败检测的参考信号时生成的指示信息这一特征，终端会对用于进行波束失败检测的参考信号进行检测，当没有检测到该参考信号时，便会生成未检测到参考信号的指示信息，需要说明的是，上述提到的参考信号为同步信号块(SSB)和/或信道状态信息参考信号(CSI-RS)。
步骤102，若监控到所述指示信息，根据所述指示信息进行波束状态检测。
需要说明的是，当监控到有该指示信息时，表明终端没有检测到用于进行波束失败检测的参考信号，终端根据此种情况再进行波束状态检测，以尽可能保证波束状态检测的准确性；此处的波束状态检测主要是进行波束失败检测。
需要说明的是，本公开实施例中因引入了在未检测到用于进行波束失败检测的参考信号时生成的指示信息这一参数，需要为这一参数设置一计数器，即所述指示信息对应的计数器(如，NO_RS_COUNTER)，且为该计数器设置一预设门限(即计数值的最大门限)，该预设门限由网络侧设备配置或协议约定。
进一步地，步骤102在具体实现方式时，采用如下方式中的至少一项：
A1、在检测到所述指示信息后，进行目标计数器的设置；
需要说明的是，所述目标计数器包括：所述指示信息对应的计数器和波束失败检测计数器中的至少一项；
具体地，在目标计数器包括所述指示信息对应的计数器时，进行目标计数器的设置的实现方式为：对所述指示信息对应的计数器进行计数，需要说明的是，此处计数器进行计数指的是为计数器加1的操作。具体的实现为：当终端每监控到1个未检测到的测量波束失败检测的参考信号的指示信息后，终端将该未检测到的测量波束失败检测的参考信号的指示信息对应的计数器的计数值加1。
具体地，在目标计数器包括波束失败检测计数器时，进行目标计数器的设置的实现方式为：维持波束失败检测计数器的计数值不变；或
重置所述波束失败检测计数器的计数值。
具体的实现为，当终端每监控到1个未检测到的测量波束失败检测的参考信号的指示信息后，终端将当前的波束失败检测计数器(BFI_COUNTER)维持不变(即保持当前计数值不变)或重置该波束失败检测计数器(即设置波束失败检测计数器为初始值，如“0”)。
A2、当所述指示信息对应的计数器的计数值达到预设门限时，进行波束失败检测计数器的设置；
需要说明的是，指示信息对应的计数器的计数值达到预设门限指的是计数器的计数值大于或等于预设的最大门限值；进行波束失败检测计数器的设置的具体方式为：重置所述波束失败检测计数器的计数值；或
对所述波束失败检测计数器进行计数。
例如，在指示信息对应的计数器的计数值达到预设门限时，终端重置当前的波束失败检测计数器(即设置波束失败检测计数器为初始值，如“0”)或将波束失败检测计数器的计数值进行加1处理。
A3、当满足检测到所述指示信息和所述指示信息对应的计数器的计数值达到预设门限中的至少一项时，进行波束失败检测定时器的设置；
需要说明的是，在此种方式下进行波束失败检测定时器的设置可以采用如下方式中的一项实现：
A31、维持波束失败检测定时器的计数值不变；
A32、停止运行所述波束失败检测定时器；
A33、启动或重启动所述波束失败检测定时器。
例如，当终端每监控到1个未检测到的测量波束失败检测的参考信号的指示信息后，终端将当前的波束失败检测定时器(beam Failure Detection Timer)维持不变(即保持当前计数值不变，并继续运行)，或停止该波束失败检测定时器(即设置为初始值，如“0”，并停止运行该定时器)，或启动(若波束失败检测定时器之前没有启动，此处称之为启动)波束失败检测定时器，或重启动(若波束失败检测定时器之前已经启动，此处称之为重启动)波束失败检测定时器。
例如，在指示信息对应的计数器的计数值达到预设门限时，将当前的波束失败检测定时器维持不变(即保持当前计数值不变，并继续运行)，或停止该波束失败检测定时器(即设置为初始值，如“0”，并停止运行该定时器)，或启动(若波束失败检测定时器之前没有启动，此处称之为启动)波束失败检测定时器，或重启动(若波束失败检测定时器之前已经启动，此处称之为重启动)波束失败检测定时器。
A4、当所述指示信息对应的计数器的计数值达到预设门限时，确定波束状态为波束失败；
在此种方式下，只要获取到指示信息对应的计数器的计数值大于或等于预设门限(即预设的最大门限值)，就可以直接确定为波束失败。
A5、当波束失败检测定时器超时，重置所述指示信息对应的计数器的计数值；
需要说明的是，此种实现方式在波束失败检测定时器超时，将所述指示信息对应的计数器的计数值设置为初始值，如“0”。
需要说明的是，因终端的物理层会通过对波束接收，得到波束失败指示，进一步地，本公开实施例的步骤102在具体实现方式时，还包括：
获取波束失败指示；
根据所述波束失败指示和所述指示信息，进行波束状态检测。
具体地，根据所述波束失败指示和所述指示信息，进行波束状态检测可以采用如下方式实现：
A6、当检测到波束失败指示，重置所述指示信息对应的计数器的计数值。
此种实现方式具体为：当终端每检测到1个波束失败指示(如，“beam  failure instance indication”)后，终端将指示信息对应的计数器重置(即设置为初始值，如“0”)。
需要说明的是，本公开实施例中终端在执行步骤102时，可以采用上述的A1-A6中的一项或多项的任意组合实现。
这里还需要说明的是，终端对波束状态检测还包括以下行为：
B1、当终端检测到1个波束失败指示后，终端将波束失败检测计数器进行累加(如，BFI_COUNTER＝BFI_COUNTER+1)；
B2、当终端检测到1个波束失败指示后，终端启动或重启动波束失败检测定时器；
B3、当波束失败检测定时器超时时，将波束失败检测计数器重置(如，设置为“0”值)；
B4、当波束失败检测计数器达到最大计数门限值(如，波束失败检测计数器的计数值大于或等于最大计数门限值)，终端认为该检测的波束发生了波束失败；
需要说明的是，此方式下的波束失败检测计数器的最大计数门限值由网络侧设备配置或协议约定。
还需要说明的是，当进行波束状态检测之后，发生波束失败时，终端会触发波束失败恢复过程。
需要说明的是，本公开实施例，终端可以根据在未检测到参考信号时是否生成指示信息这一参数进行波束状态的监测，从而让终端的波束状态检测的结果更接近测量波束失败检测用的参考信号发送情况的波束状态，减少误判出现波束失败的概率，保证了波束状态检测的准确性，进而保证了网络通信的可靠性。
