下面结合附图介绍本公开的实施例。本公开的一些实施例提供的配置物理下行控制信道的方法、用户设备和网络侧设备可以应用于无线通信***中。该无线通信***可以为采用5G***,或者演进型长期演进(Evolved Long Term Evolution,eLTE)***,或者后续演进通信***。
请参见图1,图1是本公开的一些实施例可应用的一种网络***的结构图,如图1所示,包括终端11和至少一个基站12,其中,终端11可以是用户终端(User Equipment,UE)或者其他终端侧设备,例如:手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant,简称PDA)、移动上网装置(Mobile Internet Device,MID)或可穿戴式设备(Wearable Device)等终端侧设备,需要说明的是,在本公开的一些实施例中并不限定终端11的具体类型。上述基站12可以是 4G基站,或者5G基站,或者以后版本的基站,或者其他通信***中的基站,或者称之为节点B,演进节点B,或者所述领域中其他词汇,只要达到相同的技术效果,所述基站不限于特定技术词汇。另外,上述基站12可以是主基站(Master Node,MN),或者辅基站(Secondary Node,SN)。需要说明的是,在本公开的一些实施例中仅以5G基站为例,但是并不限定基站的具体类型。
请参见图2,图2是本公开的一些实施例提供的无线链路恢复方法的流程图,该方法应用于终端,如图2所示,包括以下步骤:
步骤201、进行RLM。
其中,该步骤可以是对多个指定小区进行RLM,通过RLM以判断这些指定小区是否发生RLF。
本公开的一些实施例中,一个服务基站可以存在一个或者多个指定小区(也可以称作特定小区)。另外,服务基站存在的指定小区可以是基站配置的,也可以是协议中定义的,例如:协议可以预先定义PCell、PScell和/或物理上行链路控制信道(Physical Uplink Control Channel,PUCCH)Scell为指定小区,其中,PUCCH Scell可以是指为所述UE配置了PUCCH的辅小区。
需要说明的是,本公开的一些实施例,对通过RLM判定小区发生RLF的方式不作限定,下面以一种判定小区发生RLF的方式进行举例:
对指定小区进行RLM可以是测量指定小区的物理下行控制信道(Physical Downlink Control Channel,PDCCH)对应的小区参考信号(Cell Reference Signal,CRS)的信号与干扰加噪声比(Signal to Interference plus Noise Ratio,SINR)。当终端物理层(L1)测量到该指定小区的PDCCH对应的CRS参考信号的SINR低于一定门限,则认定该无线链路失步(out-of-sync);物理层通知高层(例如:RRC层,L3)一个out-of-sync指示,如果RRC层连续N310(N310为一预配置数值,例如:3、5或者10)个out-of-sync指示,则终端RRC层开启一个定时器T310。在T310开启后,如果物理层测量的该指定小区的PDCCH对应的CRS参考信号高于一定门限则认定该无线链路同步(in-sync),则物理层通知高层(RRC层)一个in-sync指示,如果RRC层连续N311(N311为另一个预配置数值,例如:2、6或者10)个in-sync 指示,则终端停止定时器T310的运行。但如果定时器T310运行超时了,则终端判定该指定小区发生RLF。
当然,本公开的一些实施例中,也可以采用LTE***中RLM和RLF机制来判定小区是否发生RLF。
步骤202、在监测到多个指定小区发生RLF的情况下,发起无线链路恢复流程,和/或,在监测到指定小区发生RLF的情况下,进行该指定小区的RLF上报。
该步骤中,上述多个指定小区可以是不同服务基站的多个小区,例如:双连接场景中,当监测到主基站的指定小区发生RLF,以及辅助基站的指定小区发生RLF时,则可以发起无线链路恢复流程。或者,上述多个指定小区可以是同一个基站的多个指定小区,例如:单连接场景中,服务基站的多个指定小区发生RLF,则可以发起无线链路恢复流程。
上述步骤中,由于在监测到多个指定小区发生RLF的情况下,才发起无线链路恢复流程,这样可以避免终端频繁执行的无线链路恢复流程,以减少终端数据中断的频次,进而提高终端的通信性能。另外,在监测到多个指定小区发生RLF时,终端可以确认为终端RLF(或者称作UE RLF)或小区组RLF,并发起无线链路恢复流程,这样可以避免终端频繁发生UE RLF或小区组RLF。其中,上述小区组RLF可以是辅小区组(Secondary Cell Group,SCG)RLF或者主小区组(Master Cell Group,MCG)RLF。
另外,本公开的一些实施例中,对不存在多个指定小区发生RLF的情况不作限定,例如:终端存在两个服务基站,每个服务基站存在一个指定小区,这样其中一个服务基站的指定小区未发生RLF,则可以继续执行步骤201,或者结束流程。
上述在监测到指定小区发生RLF的情况下,进行该指定小区的RLF上报可以是,监测到一个指定小区发生RLF的情况下,则进行该指定小区的RLF上报,例如:上报该指定小区或者该指定小区的服务基站发生RLF;或者,可以是监测到某一服务基站的多个指定小区(例如:全部指定小区)发生RLF的情况下,则进行该指定小区的RLF上报,例如:上报该指定小区的服务基站发生RLF。这样相比相关技术,只有监测到小区发生RLF,则发起无线链 路恢复流程,本公开的一些实施例中,可以避免终端频繁执行的无线链路恢复流程,以减少终端数据中断的频次,进而提高终端的通信性能。
另外,进行该指定小区的RLF上报(例如:上报该指定小区或者该指定小区的服务基站发生RLF)后,网络侧可以将该指定小区或者该服务基站从终端的小区列表或者基站列表中去除,以避免终端继续在该指定小区或者该服务基站的小区进行接收和发送,以节约终端功耗,另外,还可以避免该服务基站继续调度终端进行数据传输,或者该服务基站在该指定小区中继续调度终端进行数据传输,降低干扰,提升资源利用率。当然,网络侧还可以为终端配置新的服务基站或者小区,提升终端吞吐量。
需要说明的是,步骤202中的和/或表示步骤202可以包括如下三种情况:
在监测到多个指定小区发生无线链路失败RLF的情况下,发起无线链路恢复流程;或者
在监测到指定小区发生RLF的情况下,进行该指定小区的RLF上报;或者
在监测到多个指定小区发生无线链路失败RLF的情况下,发起无线链路恢复流程,和,在监测到指定小区发生RLF的情况下,进行该指定小区的RLF上报。
需要说明的是,本公开的一些实施例中提供的上述方法可以应用于5G NR***,但对此不作限定,只要能够实现基本相同的功能,适用于其他通信***,例如:可以应用4G或者6G***或者其他应用无线链路恢复流程的通信***等等。
本公开的一些实施例中,进行RLM;在监测到多个指定小区发生无线链路失败RLF的情况下,发起无线链路恢复流程,和/或,在监测到指定小区发生RLF的情况下,进行该指定小区的RLF上报。这样相比相关技术单一小区发生RLF后,则发起无线链路恢复流程,本公开的一些实施例,可以提高终端的通信性能。
请参见图3,图3是本公开的一些实施例提供的无线链路恢复方法的另一示例的流程图,该方法应用于终端,如图3所示,包括以下步骤:
步骤301、进行RLM。
步骤302、在监测到多个指定小区发生无线链路失败RLF的情况下,发起无线链路恢复流程。
作为一种可选的实施方式,所述进行RLM,包括:
在所述终端工作于双连接模式或者多连接模式的情况下,对每个服务基站的指定小区进行RLM;或者
在所述终端工作于单连接模式的情况下,对服务基站的多个指定小区进行RLM。
该实施方式中,可以实现双连接模式或者多连接模式下,对每个服务基站的指定小区进行RLM,以判定这些指定小区是否发生RLF。
由于每个服务基站的指定小区进行RLM,终端发起无线链路恢复流程时需要参考更多服务基站的信号强度,以进一步避免终端频繁发起无线链路恢复流程。
另外,在双连接模式或者多连接模式下,每个服务基站可以存在一个或者多个指定小区,且不同服务基站存在的指定小区的数量可以相同或者不同,对此不作限定。例如:所述对每个服务基站的指定小区进行RLM,包括:
对每个服务基站的一个指定小区进行RLM;或者
对每个服务基站的多个指定小区进行RLM。
其中,对每个服务基站的一个指定小区进行RLM可以实现在多个服务基站的指定小区发生RLF时,才发起无线链路恢复流程,以进一步避免终端频繁发起无线链路恢复流程。例如:双连接模式下主基站的指定小区和辅基站的指定小区都发生RLF时,才发起无线链路恢复流程。
而上述对每个服务基站的多个指定小区进行RLM可以是,每个服务基站存在多个指定小区进行的,这样可以实现基于更多指定小区的RLF来判定是否发起无线链路恢复流程。例如:主基站有两个指定小区,而辅基站有两个或者三个指定小区,这样当主基站的至少一个指定小区发生RLF,以及辅基站的至少一个指定小区发生RLF时,才发起无线链路恢复流程。可选的,可以是所有指定小区均发生RLF时,才发起无线链路恢复流程。
另外,上述实施方式中,还可以实现在单连接模式下,对服务基站的多个指定小区进行RLM,从而实现在该服务基站多个或者所有指定小区发生 RLF时,才发起无线链路恢复流程,以进一步避免终端频繁发起无线链路恢复流程。
可选的,一种实施方式,所述在监测到多个指定小区发生RLF的情况下,发起无线链路恢复流程,包括:
在监测到多个服务基站的指定小区发生RLF的情况下,发起无线链路恢复流程。
其中,上述监测到多个服务基站的指定小区发生RLF可以是,检测多个服务基站均存在发生RLF的指定小区。但这里并不限定这多个服务基站的所有指定小区均发生RLF。由于监测到多个服务基站的指定小区发生RLF的情况下,才发起无线链路恢复流程,从而可以进一步避免终端频繁发起无线链路恢复流程。当然,在一种可选的实施方式,可以是多个或所有服务基站的所有指定小区均发生RLF时,才发起无线链路恢复流程,这样可以使得终端的通信性能更佳。
所述终端工作于双连接模式或者多连接模式,所述在监测到多个服务基站的指定小区发生RLF的情况下,发起无线链路恢复流程,可以包括:
若每个服务基站存在一个指定小区,则在监测多个指定小区发生RLF的情况下,发起无线链路恢复流程;或者
若每个服务基站存在多个指定小区,则在监测到每个服务基站的多个指定小区发生RLF的情况下,发起无线链路恢复流程。
在每个服务基站存在一个指定小区的情况下,上述在监测多个指定小区发生RLF可以是,监测到多个服务基站的指定小区发生RLF,因为,每个服务基站配置一个指定小区。可选的,可以是检测到所有服务基站的指定小区均发生RLF,才发起无线链路恢复流程,这样可以避免当主服务基站(例如:MN)PCell上RLF时,即使辅服务基站(例如:SN)PScell上的信号质量还很好,UE和网络侧的连接也发生中断的情况,进而可以使得终端的通信性能更佳。
需要说明的是,在每个服务基站配置多个指定小区的情况下,上述在监测到每个服务基站的多个指定小区发生RLF,并不限定某服务基站发生RLF的指定小区的数量等于该服务基站存在的指定小区的数量。例如:某服务基 站存在三个指定小区,则监测到该服务基站的两个指定小区发生RLF时,则认为监测到该服务基站的多个指定小区发生RLF。当然,本公开的一些实施例中,可选的是监测每个服务基站的所有指定小区均发生RLF,对发起无线链路恢复流程,这样可以使得终端的通信性能更佳。
当然,本公开的一些实施例中,还存在其他场景,例如:在双连接模式或者多连接模式下,某些服务基站只有一个指定小区,而另一些服务基站存在多个指定小区,则可以是在监测到只有一个指定小区的服务基站的指定小区发生RLF,以及存在多个指定小区的服务基站的多个指定小区发生RLF,则发起无线链路恢复流程,这样可以提高终端的灵活性,以适应不同的场景或者业务需求。
可选的,另一种实施方式,所述在监测到多个指定小区发生RLF的情况下,发起无线链路恢复流程,包括:
在监测到主基站的多个指定小区发生RLF的情况下,发起无线链路恢复流程,其中,所述主基站为所述双连接模式或者所述多连接模式下的主基站,或者所述主基站为所述单连接模式中的服务基站。
该实施方式中,可以实现只要主基站的多个指定小区发生RLF,则终端发起无线链路恢复流程,这样可以使得终端更加灵活地发起无线链路恢复流程,但可以避免频繁发起无线链路恢复流程,使得终端的通信性能更佳。
需要说明的是,在监测到主服务基站的多个指定小区发生RLF的情况下,发起无线链路恢复流程可以是,主服务基站的所有指定小区发生RLF的情况下,发起无线链路恢复流程。当然,如果主服务基站存在三个或者三个以上的指定小区,则也可以是监测到主服务基站两个或者两个以上的指定小区发生RLF,则发起无线链路恢复流程,对此不作限定。
可选的,所述在监测到多个指定小区发生RLF的情况下,发起无线链路恢复流程,包括:
在监测到多个指定小区发生RLF时,启动定时器;
在所述定时器运行期间,执行小区选择过程;
若选择符合特定条件的小区,则针对该小区执行无线资源控制(Radio Resource Control,RRC)连接重建过程。
其中,上述定时器可以是网络配置的,或者协议中定义的,对此不作限定。
该实施方式中,可以实现在定时器运行期间若选择符合特定条件的小区,则针对该小区执行RRC连接重建过程,以恢复无线链路,这样可以提高恢复无线链路的成功率。其中,上述符合特定条件的小区可以是找到合适的小区,例如:找到信号强度高于一定门限的小区,或者查找到信道质量满足一定条件的小区等,对此不作限定。当然,上述特定小区可以是终端预先配置的,或者网络配置的,或者协议预先定义的等。
当然,本公开的一些实施例中,发起无线链路恢复流程并不限定通过上述方式发起,例如:还可以是不启动上述定时器,只要找到适合的小区,则针对该小区发起RRC连接重建过程。
可选的,上述方法还可以包括如下步骤:
步骤303、在监测到指定小区发生RLF的情况下,进行该指定小区的RLF上报。
其中,步骤303中的指定小区可以是发生RLF的一个或者多个指定小区。另外,步骤303中可以是在监测到指定小区发生RLF的情况下,在与该指定小区不同的一个或者多个其他小区中,进行该指定小区的RLF上报。例如:第一指定小区发生RLF,则可以在其他未发生RLF的一个或者多个小区进行第一指定小区的RLF上报。从而可以提高上报的成功率。
需要说明的是,本实施例中,对步骤303与步骤301的时序不作限定,例如:303可以是在步骤301之后选择,也可以是在执行步骤301的过程中执行步骤303,因为,步骤301可以对多个指示小区,以及对多个服务基站的指定小区进行RLM,这样在监测过程中可以满足了上报条件,从而步骤303可以进行相应的上报。另外,本实施例中可以包括步骤302和步骤303中的至少一项,也就是说,一种实施方式中可以只包括步骤302或者步骤303,在另一种实施方式中,可以包括步骤302和步骤303。
在一种实施方式中,步骤303可以包括:
若每个服务基站存在一个指定小区,在监测到指定小区发生RLF时,向网络侧上报该指定小区对应的服务基站发生RLF。
其中,上述在监测到指定小区发生RLF时,向网络侧上报该指定小区对应的服务基站发生RLF可以是,监测到某个指定小区发生RLF,但还存在至少一个服务基站的指定小区未发生RLF,则向网络侧上报该指定小区对应的服务基站发生RLF。这样上报该服务基站发生RLF后,网络侧可以将该服务基站从终端的服务基站列表中去除,以避免终端继续在该服务基站的小区进行接收和发送,以节约终端功耗,另外,还可以避免该服务基站继续调度终端进行数据传输,降低干扰,提升资源利用率。当然,网络侧还可以为终端配置新的服务基站,提升终端吞吐量。
在另一种实施方式中,步骤303可以包括:
若每个服务基站存在多个指定小区,在监测到第一指定小区发生RLF时,且所述第一指定小区对应的服务基站还存在未发生RLF的第二指定小区,则向网络侧上报所述第一指定小区发生RLF。
其中,上述第一指定小区可以是任意服务基站中的某一指定小区,同理,上述第二指定小区可以是服务基站中未发生RLF的指定小区。也就是说,当某一服务基站中一指定小区发生RLF时,若该服务基站还存在至少一个未发生RLF的指定小区,则向网络侧上报第一指定小区发生RLF。这样上报第一指定小区发生RLF后,网络侧可以将第一指定小区的服务小区列表中去除,以避免终端继续在第一指定小区进行接收和发送,以节约终端功耗,另外,还可以避免第一指定小区的服务基站在该小区内继续调度终端进行数据传输,降低干扰,提升资源利用率。当然,网络侧还可以为终端配置新的小区,提升终端吞吐量。
在另一种实施方式中,步骤303可以包括:
在所述终端工作于双连接模式或者多连接模式的情况下,若每个服务基站存在多个指定小区,在监测到辅基站的多个指定小区发生RLF时,则向网络侧上报辅基站发生RLF。
该实施方式中,可以实现在监测到辅基站的多个指定小区发生RLF时,则向网络侧上报辅基站发生RLF,例如:辅基站的所有指定小区或者部分指定小区(该部分指定小区为至少两个指定小区)均发生RLF时,向网络侧上报辅基站发生RLF。这样上报该辅基站发生RLF后,网络侧可以将该辅基站 从终端的辅基站列表中去除,以避免终端继续在该辅基站的小区进行接收和发送,以节约终端功耗,另外,还可以避免该辅基站继续调度终端进行数据传输,降低干扰,提升资源利用率。当然,网络侧还可以为终端配置新的辅基站,提升终端吞吐量。需要说明的是,该实施方式中,辅基站的多个指定小区发生RLF时,则向网络侧上报辅基站发生RLF,这里可以不考虑是否还存在其他服务基站有未发生RLF的指定小区,也说是的,如果辅基站的多个指定小区发生RLF,不管是否还存在其他服务基站有未发生RLF的指定小区,终端均可以向网络侧上报辅基站发生RLF。
在另一种实施方式中,步骤303可以包括:
在所述终端工作于双连接模式或者多连接模式的情况下,若每个服务基站存在多个指定小区,在监测到第一服务基站的多个指定小区发生RLF时,且还存在第二服务基站有未发生RLF的指定小区,则向网络侧上报第一服务基站发生RLF。
其中,上述第一服务基站可以是主基站或者辅基站。该实施方式中,可以实现若检测到一个服务基站的多个指定小区发生RLF,如果还存在有未发生RLF的指定小区的服务基站,则终端向网络侧上报第一服务基站发生RLF。其中,该实施方式的有益效果,可以参见上述上报服务基站发生RLF的有益效果,此处不作赘述。
在另一种实施方式中,步骤303可以包括:
在监测到指定小区发生RLF的情况下,在与该指定小区不同的一个或者多个其他小区中,向网络侧上报该指定小区或者该指定小区的服务基站发生RLF。
该实施方式中,可以实现一个小区发生RLF时,可以在其他小区中进行该小区的RLF上报,从而可以提高上报的成功率。另外,该实施方式中,上述向网络侧上报该指定小区或者该指定小区的服务基站发生RLF可以参见,上述四种上报小区或者基站发生RLF的情况。例如:若每个服务基站存在一个指定小区,在监测到第一指定小区发生RLF时,在第二指定小区向网络侧上报第一指定小区对应的服务基站发生RLF;或者,若每个服务基站存在多个指定小区,在监测到第一指定小区发生RLF时,且所述第一指定小区对应 的服务基站还存在未发生RLF的第二指定小区,则在第二指定小区或者其他服务基站的小区向网络侧上报所述第一指定小区发生RLF;或者,在所述终端工作于双连接模式或者多连接模式的情况下,若每个服务基站存在多个指定小区,在监测到第一辅基站的多个指定小区发生RLF时,则在第二辅基站或者主基站的小区向网络侧上报第一辅基站发生RLF;或者在所述终端工作于双连接模式或者多连接模式的情况下,若每个服务基站存在多个指定小区,在监测到第一服务基站的多个指定小区发生RLF时,且还存在第二服务基站有未发生RLF的指定小区,则在第二服务基站或者其他服务基站的小区向网络侧上报第一服务基站发生RLF。
可选的,在上述多种实施方式中,所述终端通过配置的调度请求(Scheduling Request,SR)资源向网络侧上报指定小区或者服务基站发生RLF;或者
所述终端通过配置的随机接入信道(Random Access Channel,RACH)资源向网络侧上报指定小区或者服务基站发生RLF。
其中,终端可以预先被配置有上述SR资源或者RACH资源,其中,该配置可以由网络配置,或者协议预先定义。该实施方式中,可以实现通过SR资源或者RACH资源向网络侧上报指定小区或者服务基站发生RLF,从而不需要配置额外的资源,以节约资源利用率。
可选的,所述终端配置有SR资源或者RACH资源与指定小区的映射关系,其中,同一个指定小区对应一个或者多个SR资源,或者同一个指定小区对应一个或者多个RACH资源;和/或,配置有SR资源或者RACH资源与服务基站的映射关系,其中,同一个服务基站对应一个或者多个SR资源,或者同一个服务基站对应一个或者多个RACH资源;
所述终端通过指定小区对应的SR资源中的一个或者多个SR资源上报该指定小区发生RLF;或者
所述终端通过指定小区对应的RACH资源中的一个或者多个RACH资源上报该指定小区发生RLF;或者
所述终端通过服务基站对应的SR资源中的一个或者多个SR资源上报该服务基站发生RLF;或者
所述终端通过服务基站对应的RACH资源中的一个或者多个RACH资源上报该服务基站发生RLF。
其中,上述SR资源或者RACH资源与指定小区的映射关系,以及SR资源或者RACH资源与服务基站的映射关系可以是,一一映射关系或者一对多映射关系,也就是说,可以为每个指定小区配置一个或者多个SR资源或RACH资源,或者可以为每个基站配置一个或者多个SR资源或RACH资源。当然,每个指定小区或者基站配置的SR资源或RACH资源的个数可以是相同的或者不同的,对此不作限定。
另外,上述通过指定小区对应的SR资源中的一个或者多个SR资源上报该指定小区发生RLF可以是,通过该指定小区对应的所有SR资源中的一个或者多个SR资源上报该指定小区发生RLF,例如:某一指定小区配置有3个SR资源,则可以通过这3个SR资源中的1个、2个或者3个SR资源进行上报。另外,选择多个SR资源或多个RACH资源中如何选择上报的资源可以存在多种实施方式,例如:先到先用,或者信号好的优先用,或者多个一起用,一个失败了再用另外一个等,对此不作限定。
该实施方式中,可以实现当终端需要上报小区RLF或基站RLF时,利用与该小区或基站对应的SR资源或RACH资源进行上报,以使得网络侧更加容易确定发生RLF的小区或者基站,以提高网络工作效率。另外,通过个SR资源或者RACH资源上报,可以是发送对应的SR或RACH,以向网络侧上报指定小区或者基站发生RLF。
作为一种可选的实施方式,所述多个指定小区中存在与多个小区的PUCCH对应的指定小区,所述终端通过该指示小区对应的多个小区的PUCCH中的至少一个PUCCH上报该指定小区的信道质量指示(Channel Quality Indicator,CQI)信息。
其中,上述与多个小区的PUCCH对应的指定小区可以是,该指示小区的CQI信息可以承载在多个小区的PUCCH上传输.如果使用这多个小区的PUCCH中的多条PUCCH上传输CQI信息时,多条PUCCH上传输CQI信息是相同的,也就是说,进行冗余备份传输,多条PUCCH使用多个小区的资源进行传输。通过该实施方式的冗余上报,保证网络对CQI信息的接收,便 于网络及时发现下行链路质量恶化。另外,该实施方式中,上述指示小区对应的多个小区的PUCCH,其中,这多个小区包括该指示小区本身,以及其他小区。
另外,上述CQI信息可以反映小区下行链路的质量。上述终端通过指定小区对应的多个小区的PUCCH中的至少一条PUCCH上报该指定小区的CQI信息可以是,终端可以通过多个小区中的一个或者多个小区的PUCCH上报该指定小区的CQI信息。
该实施方式中,可以实现为同一指定小区配置多个PUCCH,且这多个PUCCH属于不同的小区,例如:终端被配置了两个指定小区(可以属于同一个或多个基站)进行RLM,如Cell1和Cell2;这样终端可以被配置在Cell1的PUCCH上传输cell1和cell2的CQI信息;同时,被配置在cell2的PUCCH上传输cell1和cell2的CQI信息;这样,终端可以在cell1的PUCCH上传输cell1和cell2的CQI信息,以及可以在cell2的PUCCH上传输cell1和cell2的CQI信息。这样可以避免小区信号质量不好时,在本小区上报CQI,网络无法接收,通过该实施方式的冗余上报,保证网络对CQI信息的接收,便于网络及时发现下行链路质量恶化。
作为一种可选的实施方式,所述进行RLM之后,所述方法还包括:
在一个指定小区发生波束失败的情况下,通过另一个指定小区的RACH资源上报所述一个指定小区的发生波束失败的通知消息;
若上报所述一个指定小区的发生波束失败的通知消息的上报次数达到预设最大次数,且上报仍未成功,则发起无线链路恢复流程。
其中,上述一个指定小区可以是任意发生波束失败的指定小区(Beam failure),则上述另一个指定小区可以是终端选择的信道质量较好或者最好的指定小区,从而通过信道质量较好或者最好的指定小区上报波束失败。可选的,多个指定小区配置有RACH资源,所述另一个指定小区为所述终端在配置有RACH资源的多个指定小区中选择的指定小区,如选择这多个指定小区中信道质量较好或者最好的指定小区,从而可以实现一旦发生波束失败,终端选择信号质量好的指定小区上报,从而减少RACH尝试达到最大次数,仍未上报成功的概率。
另外,上述若上报所述一个指定小区的发生波束失败的通知消息的上报次数达到预设最大次数,且上报仍未成功,则发起无线链路恢复流程可以是,上报上述指定小区的发生波束失败的通知消息达到预设最大次数,但一直没有上报成功,从而终端可以判定UE RLF,进而发起无线链路恢复流程。这样可以实现避免终端频繁执行的无线链路恢复流程,以减少终端数据中断的频次,进而提高终端的通信性能。其中,上述预设最大次数可以是终端预先配置的,或者协议中预先定义的,或者网络预先配置的等。
另外,该实施方式中,可以实现终端可以在两种情况下发起无线链路恢复流程,一种是步骤302的情况,另一种该实施方式提供的情况,以提高终端发起无线链路恢复流程的灵活性。需要说明的是,该实施方式中发起的无线链路恢复流程可以参见步骤302中的发起的无线链路恢复流程,此处不作赘述。
本实施例中,在图2所示的实施例的基础上增加了多种可选的实施方式,且均可以提高终端的通信性能,以及还可以达到节约终端功耗,以及提高资源利用率等有益效果。
下面以多个实施例,对本公开的一些实施例提供的无线链路恢复方法进行举例说明:
例1:
UE被配置工作于多/双连接模式:1个MN和X个SN;当X=1时为双连接,当X>1时为多连接;
对于每一个服务基站,UE可以基于PSCell上的RLM和RLF机制,针对一个指定小区(如:Pcell或PScell)进行RLM;
当UE最后一个服务基站被判定RLF时(其他服务基站在此前已经被判定为RLF),UE在定时器T运行期间,执行小区选择过程,若找到合适的小区,UE执行RRC连接重建过程,其中,上述定时器T可以是在最后一个服务基站被判定RLF时启动的,该定时器T的时长可以是网络配置的,或者协议中定义的。
可选地,当UE的某个服务基站被判定RLF时,如果至少还有一个服务基站未被判定RLF时,UE上报node RLF(不论失败的是MN还是SN);
该方案可以避免相关方案中,当MN PCell上RLF时,即使SN PScell上的信号质量还很好,UE和NW侧的连接也发生中断。

可选地,当UE的某个服务基站的全部指定小区均被判定为RLF,但至少还有一个服务基站的一个指定小区未被判定RLF时,UE上报node RLF(不论失败的基站是MN还是SN)。
可选地,当UE的某个服务基站的一个指定小区被判定为RLF,但至少 还有一个该服务基站的指定小区未被判定RLF时,UE上报cell RLF。
例4:终端被配置了进行RLM的指定小区的CQI信息在多个cell的PUCCH上上报;
