步骤201、确定配置信息。
在本公开的一个实施例之中,该配置信息可以包括以下至少一种:
至少一个用于指示第一终端设备和第二终端设备之间的SL波束的第一指示信息,其中,该第二终端设备与第一终端设备通过SL通信;
至少一个SL波束对应承载的侧行链路波束失败检测参考信号(Sidelink Beam Failure Detection Reference Signal,SL-BFD-RS);
至少一个第一配置,该第一配置用于进行侧行链路波束失败检测(Sidelink Beam Failure Detection,SL-BFD);
至少一个第二配置,该第二配置用于进行侧行链路波束失败恢复(Sidelink Beam Failure Recovery,SL-BFR)。
其中,在本公开的一个实施例之中,上述的第一指示信息可以为SL波束对应的(SL)传输配置指示(Transmission Configuration Indicator,TCI)。
上述的第一配置可以包括以下至少一种:
预设时长;
第一门限值(如可以为波束失败最大值);
其中,该第一门限值用于:当测量到波束失败(Beam Failure,BF)发生次数达到该第一门限值,或者,当测量到在该预设时长内BF发生次数达到该第一门限值,则确定发生SL波束失败。
上述的第二配置可以包括以下至少一种:
至少一个候选恢复波束的标识;
至少一个候选恢复波束对应承载的参考信号;
用于波束恢复的第二门限值。
其中,该第二门限值具体可以用于从候选恢复波束中确定出激活的候选恢复波束,以便当发生SL波束失败时,可以基于该激活的候选恢复波束来恢复波束传输。示例的,如可以将测量结果大于第二门限值的候选恢复波束中的任一个或任多个候选恢复波束确定为激活的候选恢复波束。
进一步地,在本公开的一个实施例之中,不同的SL-BFD-RS可以对应不同的第一配置;和/或,不同的SL-BFD-RS可以对应不同的第二配置。其中,每个第一配置用于对其对应的SL-BFD-RS进行SL-BFD,每个第二配置用于对其对应的SL-BFD-RS进行SL-BFR。
示例的,如SL-BFD-RS#1可以对应第一配置#1和第二配置#1;SL-BFD-RS#2可以对应第一配置#2和第二配置#2。则此时,第一配置#1可以用于对SL-BFD-RS#1进行SL-BFD(即可以用第一配置#1中的预设时长和/或第一门限值来对SL-BFD-RS#1进行SL-BFD),第二配置#1可以用于对SL-BFD-RS#1进行SL-BFR(即可以用第二配置#1中的候选恢复波束和/或第二门限值来对SL-BFD-RS#1进行SL-BFD),第一配置#2可以用于对SL-BFD-RS#2进行SL-BFD(即可以用第一配置#2中的预设时长和/或第一门限值来对SL-BFD-RS#2进行SL-BFD),第二配置#2可以用于对SL-BFD-RS#2进行SL-BFR(即可以用第二配置#2中的候选恢复波束和/或第二门限值来对SL-BFD-RS#2进行SL-BFD)。
步骤202、响应于基于配置信息确定SL波束失败,触发SL波束失败恢复流程。
其中,在本公开的一个实施例之中,该基于配置信息确定SL波束失败的方法可以为:
测量SL-BFD-RS并确定BF发生次数是否满足预设条件,响应于确定BF发生次数满足预设条件,确定SL波束失败。
其中,在本公开的一个实施例之中,具体可以基于第一配置来测量SL-BFD-RS以确定BF发生次数是否满足预设条件。该预设条件可以为:BF发生次数超过第一门限值,和/或,在预设时长内BF发 生次数超过第一门限值。
具体的,第一终端设备在测量SL-BFD-RS的过程中,可以检测是否发生了BF,并对BF发生次数进行计数,其中,当第一终端设备的物理层接收到第一终端设备的其他层发送的SL波束失败指示(Beam Failure Indication,BFI)时,则确认检测到发生了BF,由此,通过统计第一终端设备接收到SL BFI指示的次数即可实现对BF发生次数的计数。其中,当BF发生次数达到第一门限值时,则确定满足预设条件,否则,确定不满足预设条件。
或者,第一终端设备在测量SL-BFD-RS的过程中,若检测到初次发生BF,则启动定时器并开始对BF发送次数进行计数,其中,该定时器的定时时长为上述预设时长,以及,当定时器启动期间,BF发生次数达到第一门限值时,则确定满足预设条件,否则,确定不满足预设条件。需要说明的是,当基于定时器测量SL-BFD-RS时,若该定时器超时,则会将BF发生次数的计数值置零,以防止此次的BF发生次数的计数值影响下一次SL-BFD-RS测量过程中的BF发生次数的计数。
以及,当确定出BF发生次数满足预设条件时,则说明发生SL波束失败,此时即需要触发SL波束失败恢复流程以进行波束恢复,其中,关于第一终端设备具体如何触发SL波束失败恢复流程的详细内容会在后续实施例进行介绍。
