技术领域
本申请属于通信技术领域，具体涉及一种波束检测方法、终端及网络侧设备。
背景技术
通常，终端会周期性地接收波束失败检测参考信号(Beam Failure Detection-Reference Signal，RS，BFD-RS)并进行测量，并根据测量结果判断是否发生波束失败事件。在一些场景中，网络侧设备可能由于一些原因而无法发送BFD-RS，例如，在非授权频谱中，网络侧设备可能由于先听后说(Listen Before Talk，LBT)失败没有成功接入信道，BFD-RS无法发送。然而，根据相关技术中的方案，终端依然会默认发生了波束失败事件，并上报波束失败实例(Beam Failure Instance，BFI)。这样大大的增加了BFI的概率，使得终端认为波束失败而发起波束失败恢复流程，消耗较多的通信资源。
发明内容

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波束检测方法进行详细地说明。
如图2所示，本申请实施例提供一种波束检测方法200，该方法可以由终端执行，换言之，该方法可以由安装在终端的软件或硬件来执行，该方法包括如下步骤。
S202：终端优先通过优先级最高的传输配置指示(Transmission Configuration Indicator，TCI)状态(state)检测波束失败检测参考信号(Beam Failure Detection-Reference Signal，RS，BFD-RS)。
其中，所述终端被配置有多个TCI状态，所述多个TCI状态中的每个TCI状态对应有优先级。该实施例中，网络侧设备可以为每个TCI状态配置优先级；或者，该TCI状态对应的优先级可以等同于BFD-RS的优先级，其中，网络侧设备可以为BFD-RS配置优先级，BFD-RS的配置中可以包括TCI状态。
该实施例执行之前，终端和网络侧设备之间可能已经经过了波束训练过程，从而确定出最优的波束，该最优的波束可以是上述优先级最高的TCI状态对应的波束。
该实施例中，终端优先通过优先级最高的TCI状态检测BFD-RS，同时，终端也会优先通过该优先级最高的TCI状态接收数据和信令等。对于网络侧设备而言，网络侧设备也会优先通过上述优先级最高的TCI状态发送BFD-RS，优先通过上述优先级最高的TCI状态向终端发送数据和信令等。
S204：若通过所述优先级最高的TCI状态未检测到BFD-RS，则通过次优先级的TCI状态检测BFD-RS，或通过多个TCI状态检测多个BFD-RS，并根据所述多个BFD-RS的信号质量选择BFD-RS链接。
上述BFD-RS可以是周期性发送的，因此，该步骤中提到的未检测到BFD-RS，可以是在一个检测周期内未检测到BFD-RS；还可以是在多个连续的周期内均未检测到BFD-RS。该实施例中提到的未检测到BFD-RS，可以是检测的BFD-RS的信号质量低于一定阈值，该信号质量可以通过参考信号接收功率(Reference Signal Receiving Power，RSRP)，信干噪比(Signal to Interference plus Noise Ratio，SINR)，误块率(BLock Error Rate，BLER)等参数指标进行判断。
该步骤中提到的次优先级可以是第二高优先级。
该实施例例如，网络侧设备为终端配置有TCI状态1，TCI状态2和TCI状态3，TCI状态1的优先级最高，TCI状态3的优先级最低。终端优先通过TCI状态1对应的波束检测BFD-RS及接收数据和信令等；后续若通过TCI状态1对应的波束没有检测到BFD-RS，则通过TCI状态2对应的波束检测BFD-RS以及接收数据和信令等；或者，同时通过TCI状态1，TCI状态2和TCI状态3对应的波束检测BFD-RS，终端若检测到TCI状态2对应的波束上的BFD-RS的信号质量最高，则后续通过TCI状态2对应的波束检测BFD-RS以及接收数据和信令等。
本申请实施例提供的波束检测方法，网络侧设备为终端配置多个TCI状态，每个TCI状态对应有优先级，终端优先通过优先级最高的TCI状态检测BFD-RS，若后续通过优先级最高的TCI状态未检测到BFD-RS，则可以通过次优先级的TCI状态检测BFD-RS，或同时通过多个TCI状态检测多个BFD-RS，并根据多个BFD-RS的信号质量选择BFD-RS链接，本申请实施例可以减少或避免终端发起波束失败恢复流程，便于节约通信资源，提高通信效率。
可选地，在实施例200的基础上，所述方法还包括：所述终端通过第一 TCI状态对应的波束发送反馈信息，所述反馈信息用于确定所述第一TCI状态对应的波束是否发生波束失败，所述第一TCI状态是为所述终端配置的多个TCI状态之一。
该实施例例如，终端在通过优先级最高的TCI状态检测BFD-RS时，终端可以通过优先级最高的TCI状态对应的波束发送反馈信息，这样，网络侧设备即可根据是否接收到反馈信息，或者是根据反馈信息的内容，来确定优先级最高的TCI状态对应的波束的质量。
具体例如，反馈信息占用1比特，终端周期性的发送1比特反馈信息，告诉网络侧设备当前优先级最高的TCI状态对应的波束链接是好的。若网络侧设备在某个周期未接收到反馈信息，或者是多个连续的周期未接收到反馈信息，则认为优先级最高的TCI状态对应的波束出现问题，网络侧设备可以通过次优先级的TCI状态对应的波束发送BFD-RS以及数据和信令等。
又例如，反馈信息占用1比特，终端周期性发送反馈信息，或者是在网络侧设备的触发下发送反馈信息，“1”代表当前优先级最高的TCI状态对应的波束链接是好的；“0”代表当前优先级最高的TCI状态对应的波束链接质量不佳。
可以理解，上述第一TCI状态可以称作是终端当前使用的TCI状态，不仅包括优先级最高的TCI状态，还可以包括S204之后终端检测使用的次优先级的TCI状态等。
可选地，所述终端通过第一TCI状态对应的波束发送反馈信息包括：所述终端根据第一原则，通过第一TCI状态对应的波束发送反馈信息；其中，所述第一原则包括如下之一：1)周期性发送，所述周期可以由网络侧设备配置或协议预定义；2)根据网络侧设备的触发，非周期或周期性发送。
上述提到的网络侧设备配置或网络侧设备触发，可由RRC直接配置；也可由RRC配置，下行控制信息(Downlink Control Information，DCI)选择一种情况；也可由DCI直接配置。
可选地，所述方法还包括：所述终端接收第一配置信息，所述第一配置 信息用于配置所述反馈信息相关的如下至少之一：起始时刻，中止时刻，持续时间，周期，间隔，时频位置。
所述终端根据第一原则，通过第一TCI状态对应的波束发送反馈信息包括：所述终端根据第一原则，通过第一TCI状态对应的波束在第一信道上发送反馈信息；其中，所述第一信道包括如下1)和2)至少之一：
1)与所述第一TCI状态对应的波束相对应的物理随机接入信道(Physical Random Access Channel，PRACH)。例如，终端在PRACH上反馈信息，该PRACH与BFD-RS(如同步信号/物理广播信道信号块(Synchronization Signal and PBCH block，SSB)/CSI-RS)有对应关系，BFD-RS与第一TCI状态也存在对应关系，例如，BFD-RS与TCI状态是一一对应关系。此时，反馈信息可以是前导码(Preamble)序列，不再需要携带额外信息或者比特，便于节约信令资源开销。网络侧设备接收收到PRACH后，就知道其对应哪个BFD-RS的哪个TCI状态。
2)物理上行信道；其中，所述物理上行信道与所述第一TCI状态存在对应关系或不存在对应关系。该物理上行信道可以包括物理上行控制信道(Physical Uplink Control Channel，PUCCH)或物理上行共享信道(Physical Uplink Shared Channel，PUSCH)等。该反馈信息可以显式指示，即用比特数显式指示；该反馈信息还可以隐示指示，例如，用序列长度，序列循环移位，序列位置等隐式指示。
在所述物理上行信道与所述第一TCI状态存在对应关系的情况下，网络侧设备接收收到物理上行信道后，就知道其对应哪个BFD-RS的哪个TCI状态，无需额外的信令再来指示TCI状态，便于节约信令资源开销。
前文实施例提到终端通过优先级最高的TCI状态检测BFD-RS时，终端可以通过优先级最高的TCI状态对应的波束发送反馈信息，终端在发送反馈信息后，终端还可以在一定时间内通过优先级最高的TCI状态检测BFD-RS，若没有检测到相应BFD-RS，则在后续固定时间段内的次优先级或者第二优先级对应的BFD-RS上检测BFD-RS，该后续固定时间段可以为协议预定义。 该实施例中，网络侧设备可以根据是否收到反馈信息，在不同优先级的beam上发送信息。即，若网络侧设备收到反馈信息，则还是发送优先级最高的BFD-RS。若没有收到反馈信息，则发送次优先级或者第二优先级的RS。
或者，终端在一定时间内通过优先级最高的TCI状态检测BFD-RS，若没有检测到相应BFD-RS，则终端在一定时间内同时检测多个BFD-RS，根据收到的信号质量，选择相应的BFD-RS链接。所述信号质量可以通过RSRP/SINR/BLER等参数指标进行判断。该参数指标可以为协议预定义，或者终端自我实现。该实施例中，网络侧设备根据是否收到反馈信息或者反馈信息指示终端收到的信号质量不好，则网络侧设备在所有配置的beam上发送信息。
上述两个例子中提到的网络侧设备根据是否收到反馈信息。该判定标准可以为每次网络侧设备没有收到反馈信息，则发送次优先级或者第二优先级的BFD-RS；或者，网络侧设备没有收到的反馈信息满足一定条件，则发送次优先级或者第二优先级的BFD-RS。
所述网络侧设备没有收到的反馈信息满足一定条件。可以为在固定时间内没有收到固定数目的反馈信息，该固定时间以及固定数目由协议预定义。在一个具体的例子中，可以设置计数器，由协议预定义/网络侧设备预配置定时器时长以及计数器最大值。网络侧设备没收到反馈信号则计数器+1，然后定时器重置计时。若定时器时长内收到了反馈，则计数器重置清零。
可选地，前文各个实施例提到了网络侧设备为终端配置多个TCI状态及优先级，以下将分两个例子进行说明。
在一个例子中，所述终端可以通过接收第二配置信息获得，所述第二配置信息用于为所述终端配置BFD-RS，为所述终端配置的BFD-RS包括所述多个TCI状态，所述多个TCI状态中的每个TCI状态对应有优先级。例如，第二配置信息为终端配置多个或多组BFD-RS，每个或组BFD-RS对应一个TCI状态。该例子中，网络侧设备可以通过第二配置信息显式配置多个TCI状态以及每个TCI状态对应有优先级。
在另一个例子中，所述终端可以通过接收第三配置信息获得，所述第三配置信息用于为所述终端配置控制资源集(Control Resource SET，CORESET)，所述CORESET中包括所述多个TCI状态，所述多个TCI状态中的每个TCI状态对应有优先级。该例子例如，BFD-RS由物理下行控制信道(Physical Downlink Control Channel，PDCCH)对应的激活的多个TCI state中优先级最高的TCI state确定。即，网络侧设备预配置的CORESET中有多个TCI state，并配置相应的优先级。该例子中，网络侧设备可以通过第三配置信息隐式配置多个TCI状态以及每个TCI状态对应有优先级。
可选地，所述多个TCI状态中，每个TCI状态对应优先级是通过指示信息直接指示的；或者是根据每个TCI状态的标识大小或配置的先后顺序确定的，例如，TCI状态的标识越小，优先级越高；TCI状态配置越前，优先级越高等。
上述多个TCI状态的个数，以及优先级配置可动态更新。该更新由网络侧设备执行，可以通过无线资源控制(Radio Resource Control，RRC)或媒体接入控制控制单元(Media Access Control Control Element，MAC CE)进行更新。
在一个例子中，所述方法还包括：所述终端接收配置更新消息，所述配置更新消息用于更新如下至少之一：所述多个TCI状态的数量；所述多个TCI状态中，至少一个TCI状态对应的优先级。
为详细说明本申请实施例提供的波束检测方法，以下将结合几个具体的实施例进行说明。
实施例一
该实施例执行之前，网络侧设备(如基站)对BFD-RS的配置如下：基站对每个BFD-RS或者CORESET配置多个TCI状态(state)(假设3个beam：beam1，beam2，beam3)。每个TCI state配置相应的优先级(假设优先级顺序为beam1>beam2>beam3)。
需要说明的是，RRC动态配置CORESET的TCI state信息，一般情况下 指该多个TCI state是相邻的波束(beam)。
基站优先在TCI state优先级最高的beam上传输信息(假设为beam 1)，用户设备(User Equipment，UE，也简称为终端)也优先在TCI state优先级最高的beam(beam1)上接收信息。该TCI state的个数，以及优先级顺序可以由网络侧RRC层动态控制。
基站对UE上传反馈信息的配置：1，基站预配置UE上传反馈信号的周期；2，或者基站通过某种方式触发UE上传反馈信息，该触发方式可以由RRC直接配置。也可由RRC配置，DCI选择来实现。也可由DCI直接配置。所述配置包括如下1)至5)至少一种。
1)反馈信息的起始。
2)反馈信息的中止时刻。
3)反馈信息的持续时间。
4)反馈信息的周期/间隔。
5)反馈信息的时频位置。
该实施例包括如下步骤：
步骤1：UE检测BFD-RS信号(在beam1上)，该BFD-RS与CORESET中的最高优先级的TCI state是类型D准共址(Quasi co-location(QCL)type D)关系。
步骤2：UE会在一定时间内/或者周期性的一直上报当前的beam信息。告诉基站当前的beam链接是否成功。该上报可基于如下1)或2)中的信道。
1)可以通过PRACH上传反馈信息。该PRACH与BFD-RS(SSB)有对应关系。此时，反馈信息就是Preamble序列，不再需要携带额外信息或者比特。基站收到PRACH后，就知道其对应哪个BFD-RS(SSB)。
2)可以通过PUCCH/PUSCH上传反馈信息。该信道可以与BFD-RS有对应关系，即类似PRACH信道与SSB信道的对应关系。该信道也可以与BFD-RS没有对应关系，其在BFD-RS对应的beam上(beam1)上传反馈信息。
该反馈信息可以显示指示，即用比特数显式指示；该反馈信息可以隐式 指示，即用序列长度，序列循环移位，序列位置等隐式指示。
步骤3：基站如果收到了UE上传的反馈信息，证明该beam并没有失败(failure)，因此基站继续在TCI state优先级最高的beam上(beam 1)传输信息。基站如果没有收到UE上传的反馈信息，证明该beam失败，因此基站在下一个优先级的beam(beam2)上传输信息。其中，基站没有收到UE上传的反馈信息的判定标准可为如下之一：
1、每次基站没有收到反馈信息，则发送次优先级或者第二优先级的RS。
2、基站没有收到的反馈信息满足一定条件，则发送次优先级或者第二优先级的RS。
上述条件可以为：在固定时间内没有收到固定数目的反馈信息，该固定时间以及固定数目可以由协议预定义。或者，可以设置计数器，由协议预定义/基站预配置计时器时长以及计数器最大值。基站没收到反馈信息则计数器+1，然后计时器重置计时。若计时器时长内收到了反馈信息，则计数器重置清零。
步骤4：UE在一定时间内检测优先级最高的beam(beam1)，若检测到该beam信息，则证明没有形成beam failure事件，继续使用beam1连接进行数据传输；若没有检测到该beam信息，则继续检测次优先级的beam(beam2)信息，若成功检测到beam2，则UE后续使用beam2进行数据接收。或者，UE在一定时间内同时检测多个BFD-RS，根据收到的信号质量，选择相应的BFD-RS链接。
实施例二
该实施例执行之前的配置过程参见实施例一，该实施例包括如下步骤：
步骤1：UE检测BFD-RS信号(在beam1上)，该BFD-RS与CORESET中的最高优先级的TCI state QCL type D的关系。
步骤2：UE会在一定时间内/或者周期性的一直上报当前的beam信息。告诉基站当前的beam链接是否成功。该上报可基于如下1)或2)中的信道。
1)可以通过PRACH上传反馈信息。该PRACH与BFD-RS(SSB)有 对应关系。此时，反馈信息就是Preamble序列，不再需要携带额外信息或者bit。基站收到PRACH后，就知道其对应哪个BFD-RS(SSB)。
2)可以通过PUCCH/PUSCH上传反馈信息。该信道可以与BFD-RS有对应关系，即类似PRACH信道与SSB信道的对应关系。该信道也可以与BFD-RS没有对应关系，其在BFD-RS对应的beam上(beam1)上传反馈信息。
该反馈信息可以显示指示，即用比特数显式指示；该反馈信息可以隐式指示，即用序列长度，序列循环移位，序列位置等隐式指示。
步骤3：基站如果收到了UE上传的反馈信息，但是反馈信息显示当前链接的beam信号质量不好，或者基站没有收到UE上传的反馈信息。则基站在所有优先级的beam上传输信息，即类似PDCCH重复(repetion)，PDCCH携带其他信息一致，但是对应的beam不一致。
步骤4：UE在一定时间内检测优先级最高的beam(beam1)，若检测到该beam信息，则证明没有形成beam failure事件，继续使用beam1连接进行数据传输；若没有检测到该beam信息，则继续检测次优先级的beam(beam2)信息，若成功检测到beam2，则UE后续使用beam2进行数据接收。或者，UE在一定时间内同时检测多个BFD-RS，根据收到的信号质量，选择相应的BFD-RS链接。
