Description

一种波束失败的处理方法及装置
相关申请的交叉引用
本申请要求在2019年07月30日提交中国专利局、申请号为201910696132.5、申请名称为“一种波束失败的处理方法及装置”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域,尤其涉及一种波束失败的处理方法及装置。
背景技术
为了提供给终端更高的传输速率,现有的无线通信系统中引入了载波聚合(carrier aggregation,CA)技术。CA技术是指为终端同时分配多个载波,终端设备从而能够在多个载波上同时进行数据传输,从而提高数据传输速率。其中,多个载波中一般包括一个主载波、一个或多个辅载波。工作在主载波的小区为主小区(primary cell,PCell),PCell是终端设备初始接入时的小区,PCell所在基站负责与终端设备之间进行无线资源控制(radio resource control,RRC)通信。工作在辅载波的小区为辅小区(secondary cell,SCell),SCell可以为终端设备提供额外的无线资源。
未来的通信系统支持的工作频段提升至6GHz以上的高频段。在高频段通信时,由于无线信号的波长较短,信号传播容易被阻挡,导致信号传播损耗较大。为此,5G系统中将采用波束赋形(beamforming,BF)技术来获得具有良好方向性的波束,以提升天线增益,改善接收端的信干噪比(signal to interference plus noise ratio,SINR)。目前,基站与终端设备采用波束通信之前,会采用波束扫描(beam sweeping)过程来确定网络设备和终端设备之间通信时使用的波束对(发送波束和接收波束)。
然而,当无线信号的传输过程中出现遮挡(比如人体、车辆、建筑物等)时,可能导致原本相互对准的波束之间发生失准,从而导致链路质量迅速下降或中断,使得终端设备进入链路失败(radio link failure,RLF)。为此,终端设备测量到当前的接收波束信道质量较差时,需要发起波束失败恢复过程。具体的,终端设备可以在基站配置的接收波束中接收来自基站的多个波束失败检测参考信号(beam failure detection reference signal,BFD RS),并根据接收到的多个波束失败检测参考信号的信号质量确定是否满足波束失败触发条件。一旦满足波束失败触发条件,终端设备则可以确定该接收波束不适合通信,从而可以向基站发送波束失败恢复请求(beam failure recovery request,BFRQ)。基站收到该波束失败恢复请求后,可以通过高层信令为终端设备重新配置接收波束以及发送波束。
目前,只是提出了上述具体的波束失败恢复过程,但是对于涉及多小区的场景下,主小区和辅小区同时出现波束失败时,如何进行波束恢复,还没有一个解决方案,是一个亟待解决的问题。

具体实施方式
下面结合说明书附图对本申请实施例做详细描述。
本申请实施例可以应用于各种移动通信系统,例如:新无线(new radio,NR)系统、长期演进(long term evolution,LTE)系统、先进的长期演进(advanced long term evolution,LTE-A)系统、通用移动通信系统(universal mobile telecommunication system,UMTS)、演进的长期演进(evolved long term evolution,eLTE)系统、未来通信系统等其它通信系统,具体的,在此不做限制。
为便于理解本申请实施例,首先以图1中示出的通信系统为例详细说明适用于本申请实施例的通信系统。图1示出了适用于本申请实施例提供的方法的通信系统的示意图。如图1所示,该通信系统包括网络设备和终端设备。基于图1所示的系统架构,以5G NR系统为例,5G NR系统主要通过天线阵列对信号进行波束赋形,实现通过波束为终端设备提供数据传输服务。
在图1所示的架构中,当发生波束失败(比如由于信道突然波动、意外障碍中断、终端设备位置变动等因素影响,导致网络设备与终端设备之间的波束失准),终端设备将无法解码任何下行链路(downlink,DL)信号,网络设备将无法解码任何上行链路(uplink,UL)信号,使得终端设备处于无线链路失败(radio link failure,RLF)状态。针对波束失败,目前提出一种波束失败恢复方法,其主要原理是:终端设备根据波束测量结果,确定发生波束失败时,通过随机接入资源向网络设备发送BFRQ。网络设备接收到BFRQ之后,向终端设备发送波束失败恢复响应(beam failure recovery response,BFRR)。终端设备在发送BFRQ之后,如果在协议规定的时间窗内成功接收到BFRR,则认为波束失败恢复成功,否则认为波束失败没有恢复成功。
网络设备发送BFRR之后,还可以通过高层信令向终端设备指示新的波束对。终端设备与网络设备可以使用新的波束对进行通信。
当终端设备存在多个小区时,上述波束恢复方法只适用于主小区的波束恢复。基于此,本申请实施例提供一种方法,用于解决当辅小区与主小区同时波束失败时,如何恢复波束的问题。
在本申请实施例中,终端设备,为具有无线收发功能的设备或可设置于该设备的芯片。其中,所述具有无线收发功能的设备也可以称为用户设备(user equipment,UE)、接入终端、用户单元、用户站、移动站、远方站、远程终端、移动设备、用户终端、用户代理或用户装置。在实际应用中,本申请的实施例中的终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality,VR)终端、增强现实(augmented reality,AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中 的无线终端、智慧家庭(smart home)中的无线终端等等。本申请的实施例对应用场景不做限定。本申请中将前述具有无线收发功能的设备及可设置于该设备中的芯片统称为终端设备。
在本申请实施例中,网络侧设备可以为各种制式下无线接入设备,例如演进型节点B(evolved Node B,eNB)、无线网络控制器(radio network controller,RNC)或节点B(Node B,NB)、基站控制器(base station controller,BSC)、基站收发台(base transceiver station,BTS)、家庭基站(例如,home evolved NodeB,或home Node B,HNB)、基带单元(baseband unit,BBU),无线保真(wireless fidelity,WIFI)系统中的接入点(access point,AP)、无线中继节点、无线回传节点、传输点(transmission and reception point,TRP或者transmission point,TP)等,还可以为5G(NR)系统中的gNB或传输点(TRP或TP),5G系统中的基站的一个或一组(包括多个天线面板)天线面板,或者,还可以为构成gNB或传输点的网络节点,如基带单元(BBU),或在一些部署中,gNB可以包括集中式单元(centralized unit,CU)和DU。gNB还可以包括有源天线单元(active antenna unit,简称AAU)。CU实现gNB的部分功能,DU实现gNB的部分功能,比如,CU负责处理非实时协议和服务,实现无线资源控制(radio resource control,RRC),分组数据汇聚层协议(packet data convergence protocol,PDCP)层的功能。DU负责处理物理层协议和实时服务,实现无线链路控制(radio link control,RLC)层、媒体接入控制(media access control,MAC)层和物理(physical,PHY)层的功能。AAU实现部分物理层处理功能、射频处理及有源天线的相关功能。由于RRC层的信息最终会变成PHY层的信息,或者,由PHY层的信息转变而来,因而,在这种架构下,高层信令,如RRC层信令,也可以认为是由DU发送的,或者,由DU+AAU发送的。可以理解的是,网络设备可以为包括CU节点、DU节点、AAU节点中一项或多项的设备。此外,可以将CU划分为接入网(radio access network,RAN)中的网络设备,也可以将CU划分为核心网(core network,CN)中的网络设备,本申请对此不做限定。
另外,在本申请实施例中,第一小区和第二小区均波束失败时,终端设备可以中止其中一个小区的波束失败恢复流程。需要说明的是,此处的“中止”,可以是指暂停该小区的波束失败恢复流程,待另外一个小区的波束恢复成功之后,继续该小区的波束失败恢复流程。
另外,在本申请实施例中,第一小区和第二小区均波束失败时,终端设备还终止其中一个小区的波束失败恢复流程。需要说明的是,此处的“终止”,可以是指结束该小区的波束失败恢复流程,待另外一个小区的波束恢复成功之后,不再继续该小区的波束失败恢复流程。
在本申请实施例中,第一小区和第二小区均波束失败时,终端设备可以终止其中一个小区的波束失败恢复流程。需要说明的是,此处的“终止”,可以是指直接结束该小区的波束失败恢复流程,后续可以重新发起该小区的波束失败恢复流程,或者不再执行该小区的波束失败恢复流程。
需要说明的是,本申请实施例可以应用于多个小区同时为终端设备服务的场景,包括但不限于CA场景、多TRP场景、双连接(Dual Connectivity)场景以及协同多点传输(Coordinated Multiple Points,CoMP)场景等,在此不再逐一举例说明。
本申请实施例描述的网络架构以及业务场景是为了更加清楚的说明本申请实施例的 技术方案,并不构成对于本申请实施例提供的技术方案的限定,本领域普通技术人员可知,随着网络架构的演变和新业务场景的出现,本申请实施例提供的技术方案对于类似的技术问题,同样适用。
参见图2,为本申请实施例提供的一种波束失败的处理方法流程示意图,该方法包括:
步骤201:终端设备确定第一小区的波束失败,在所述第一小区的波束失败恢复成功之前,若确定第二小区的波束失败,则中止或终止所述第一小区和所述第二小区中的辅小区的波束失败恢复流程。
可选的,终端设备确定第二小区的波束失败时,发起或继续所述第一小区和所述第二小区中的主小区的波束失败恢复流程。
其中,所述第一小区为主小区,所述第二小区为辅小区,或者,所述第一小区为辅小区,所述第二小区为主小区。为了描述方便,本申请实施例下文中的描述中,如果出现“主小区”,在没有特别说明的情况下,该“主小区”指的是第一小区和第二小区中的主小区,例如,如果第一小区是主小区,那么该“主小区”指的是第一小区,相应的,如果第二小区是主小区,那么该“主小区”指的是第二小区。相应的,本申请实施例下文中的描述中,如果出现“辅小区”,在没有特别说明的情况下,该“辅小区”指的是第一小区和第二小区中的辅小区,例如,如果第一小区是辅小区,那么该“辅小区”指的是第一小区,相应的,如果第二小区是辅小区,那么该“辅小区”指的是第二小区。
需要说明的是,步骤201中,终端设备在第一小区的波束失败恢复成功之前,确定第二小区的波束失败,可以是指以下任一种场景。第一种可能的场景,如图3所示,终端设备先在第一小区中确定第一小区的波束失败,并在发送第一小区的波束失败恢复请求之前,确定第二小区的波束失败。其中,波束失败恢复请求用于指示第一小区的波束失败,或者用于请求对波束失败进行恢复。
第二种可能的场景,如图4所示。终端设备先在第一小区中确定第一小区的波束失败,并发送第一小区的波束失败恢复请求。终端设备在接收到第一小区的波束失败恢复请求响应之前,确定第二小区的波束失败,该波束失败恢复请求响应用于响应所述第一小区的波束失败恢复请求。
本申请实施例中,终端设备确定第一小区或者第二小区的波束失败的方式可以不作限定。例如,在第一小区中,终端设备可以周期性地检测网络设备发送的波束失败检测参考信号(beam failure detection reference signal,BFD RS),如果BFD RS的信号质量小于设定的波束失败门限,则可以确定发生一次波束失败实例(beam failure instanc)。如果连续N次出现波束失败实例,则终端设备确定第一小区发生波束失败。N的值根据协议规定。
以上仅是终端设备确定波束失败的方式举例,本申请还可以应用其它方式来确定是否发生波束失败,在此不再逐一举例说明。
本申请实施例中,终端设备中止或终止辅小区的波束失败恢复流程时,可以不在辅小区中执行波束失败检测,即可以执行以下一项或多项:
所述终端设备中止或终止所述辅小区的波束失败检测定时器并复位;
所述终端设备中止或终止所述辅小区的波束失败检测计数器并复位;
所述终端设备不向所述网络设备发送所述辅小区的波束失败恢复请求信息,所述波束失败恢复请求信息用于指示所述辅小区的波束失败。
需要说明的是,波束失败检测定时器用来计时预设的时间;波束失败检测计数器用来在预设时间内对上述波束失败实例个数计数;当波束失败检测定时器未超期时,且波束失败检测计数器计数值大于一预设值时,则认为发生波束失败。
本申请实施例中,终端设备中止或终止辅小区的波束失败恢复流程的同时,为主小区执行波束恢复过程。具体的,终端设备确定主小区的波束失败后,可以在网络设备预配置的波束测量资源集合中选择一个满足预设条件的资源,并通过该资源关联的随机接入资源中发送BFRQ。当终端设备成功接收到来自网络设备的BFRR时,可以确定主小区的波束失败恢复成功。
步骤202:终端设备确定所述第一小区和所述第二小区中的主小区的波束失败恢复成功后,向网络设备发送第一信息。
其中,所述第一信息用于指示所述第一小区和所述第二小区中的辅小区的波束失败。第一信息也可以称为BFRQ等名称,本申请实施例对第一信息的名称并不限定,在此不再逐一举例说明。
需要说明的是,本申请实施例对第一信息中携带的内容并不限定,举例来说,第一信息可以包括以下任意一种或多种的组合:辅小区的波束失败的原因;辅小区的标识;新的可用波束的标识。
其中,辅小区的标识可以是任意用来标识小区的信息。类似的,新的可用波束也可以用波束ID来指示。新的可用波束,是终端设备在确定辅小区发生波束失败时,从备选波束的集合中选择出的满足预设条件的备选波束。终端设备期望网络设备采用新的可用波束向终端设备发送下行信息。其中,备选波束集合是网络设备配置给终端的。预设条件可以是波束质量高于设定备选波束质量门限等,本申请实施例对此并不限定。
一种可能的实现方式中,本申请实施例中,终端设备可以在主小区中,通过专用(dedicated)调度请求向网络设备发送第一信息。当然以上只是示例,终端设备还可以通过其他方式发送第一信息,在此不再赘述。
步骤203:网络设备接收来自终端设备的第一信息。
步骤204:网络设备根据所述第一信息恢复所述终端设备在所述辅小区中的波束。
通过上面的流程,在确定第一小区的波束失败,在所述第一小区的波束失败恢复成功之前,如果确定第二小区的波束失败,则可以中止或终止其中的辅小区的波束失败恢复流程,优先执行其中的主小区的波束失败恢复流程,从而可以保证主小区优先恢复正常通信。
步骤204中,网络设备还可以向终端设备指示辅小区中的新的可用波束,以及指示主小区中的新的可用波束。网络设备具体如何指示主小区中的新的可用波束,可以参考现有技术中的描述,本申请实施例在此不再赘述。
网络设备指示辅小区中的新的可用波束时,一种可能的实现方式中,网络设备可以显式的向终端设备指示辅小区中的新的可用波束。具体的,网络设备接收到第一信息之后,可以向终端设备发送第二信息,第二信息用于指示第一波束。其中,第一波束是终端设备在辅小区中新的可用波束,终端设备可以在所述辅小区中使用所述第一波束接收来自所述网络设备的下行数据。
网络设备可以通过多种方式发送第二信息。第一种可能的实现方式中,网络设备可以在主小区中向终端设备发送第二信息。在该实现方式下,网络设备可以通过无线资源控制 (radio resource control,RRC)信令,或者媒体接入控制(medium access control,MAC)控制元素(Control Element,CE)信令,或者下行控制信息(downlink control information,DCI)发送第二信息。
其中,RRC信令和MAC-CE信令通过物理下行共享信道(physical downlink shared channel,PDSCH)承载;DCI通过物理下行控制信道(physical downlink control channel,PDCCH)承载。
在该实现方式下,第一波束可以为网络设备选择的波束,具体如何选择,本申请实施例对此并不限定。当然,第一波束也可以通过其他方式确定,在此不再逐一举例说明。
在该实现方式下,终端设备可以在主小区中接收来自网络设备的第二信息,并使用第二信息指示的第一波束,在辅小区中接收来自所述网络设备的下行数据。
第二种可能的实现方式中,网络设备可以在第三小区中向终端设备发送第二信息。第三小区为未发生波束失败的辅小区,第三小区为除了第一小区和第二小区之外的小区。
在该实现方式下,网络设备可以通过RRC信令,或者MAC-CE信令,或者DCI在第三小区中向终端设备发送第二信息。
同样的,在该实现方式下,第一波束可以为网络设备选择的波束,具体如何选择,本申请实施例对此并不限定。当然,第一波束也可以通过其他方式确定,在此不再逐一举例说明。
本申请实施例中,网络设备也可以隐式的向终端设备指示辅小区中的新的可用波束。在该实现方式下,终端设备发送的第一信息通过第一资源发送,所述第一资源与第一波束具有关联关系,该关联关系是预先配置的。网络设备接收到第一信息之后,使用第一信息关联的第一波束向终端设备发送下行数据。当终端设备通过第一波束正确接收到下行信息时,表明第一波束可以在辅小区中使用,终端设备从而可以将所述第一波束作为所述终端设备在所述辅小区中新的可用波束。通过这种方法,可以实现加速辅小区波束失败恢复流程。
举例来说,网络设备接收到第一信息之后,网络设备在辅小区中使用第一波束发送PDCCH,终端设备如果使用第一波束成功接收到网络设备发送的PDCCH,则确定第一波束为在所述辅小区中新的可用波束。
另一种可能的实现方式中,终端设备发送第一信息所使用的第三波束,和第一波束存在关联关系。网络设备接收到第一信息之后,可以将与第三波束关联的波束作为第一波束。其中,第三波束和第一波束的关联关系是预先配置的。
本申请实施例中,终端设备确定第一小区的波束失败,在所述第一小区的波束失败恢复成功之前,若确定第二小区的波束失败,终端设备也可以中止或终止所述第一小区和所述第二小区中的主小区的波束失败恢复流程,具体可以参考以下描述。

其中,所述第一小区为主小区,所述第二小区为辅小区,或者,所述第一小区为辅小 区,所述第二小区为主小区。为了描述方便,本申请实施例下文中的描述中,如果出现“主小区”,在没有特别说明的情况下,该“主小区”指的是第一小区和第二小区中的主小区,例如,如果第一小区是主小区,那么该“主小区”指的是第一小区,相应的,如果第二小区是主小区,那么该“主小区”指的是第二小区。相应的,本申请实施例下文中的描述中,如果出现“辅小区”,在没有特别说明的情况下,该“辅小区”指的是第一小区和第二小区中的辅小区,例如,如果第一小区是辅小区,那么该“辅小区”指的是第一小区,相应的,如果第二小区是辅小区,那么该“辅小区”指的是第二小区。
步骤501中,终端设备在第一小区的波束失败恢复成功之前,确定第二小区的波束失败,可以是指图3或图4所描述的任一种场景,在此不再赘述。
在该实现方式中,终端设备中止或终止主小区的波束失败恢复流程的同时,为辅小区执行波束恢复过程。具体的,终端设备确定辅小区的波束失败后,终端设备可以在主小区中,通过专用(dedicated)调度请求向网络设备发送辅小区的波束失败恢复请求,辅小区的波束失败请求信息用于指示辅小区的波束失败,或者用于请求恢复辅小区的波束。当然以上只是示例,终端设备还可以通过其他方式发送辅小区的波束失败恢复请求,在此不再赘述。当终端设备成功接收到来自网络设备针对辅小区的波束失败恢复请求的BFRR时,可以确定辅小区的波束失败恢复成功。
步骤502:终端设备确定所述第一小区和所述第二小区中的辅小区的波束失败恢复成功后,向网络设备发送波束失败信息。
其中,所述波束失败信息用于指示所述第一小区和所述第二小区中的主小区的波束失败。波束失败信息也可以称为BFRQ等名称,本申请实施例对波束失败信息的名称并不限定,在此不再逐一举例说明。
需要说明的是,本申请实施例对波束失败信息中携带的内容并不限定,举例来说,波束失败信息可以包括以下任意一种或多种的组合:主小区的波束失败的原因;主小区的标识。
步骤503:网络设备接收来自终端设备的波束失败信息。
步骤504:网络设备根据所述波束失败信息恢复所述终端设备在所述主小区中的波束。
网络设备具体如何实现主小区的波束失败恢复,以及辅小区的波束失败恢复可以参考图2所示的流程中的描述,在此不再赘述。
本申请实施例中,终端设备确定第一小区的波束失败,且确定第二小区的波束失败时,也可以同时为第一小区和第二小区进行波束恢复,下面详细描述。
参见图6,为本申请实施例提供的一种波束失败的处理方法流程示意图,该方法包括:
步骤601:终端设备确定第一小区的波束失败,在所述第一小区的波束失败恢复成功之前,若确定第二小区的波束失败,则中止或终止所述第一小区的波束失败恢复流程,并向网络设备发送第三信息。
其中,所述第三信息至少用于指示所述第一小区和所述第二小区中的主小区的波束失败,或者第三信息至少用于指示恢复所述第一小区和所述第二小区中的主小区的波束。第三信息也可以为BFRQ等,本申请实施例对第三信息的名称并不限定,在此不再逐一举例说明。所述第一小区为主小区,所述第二小区为辅小区,或者,所述第一小区为辅小区,所述第二小区为主小区。为了描述方便,本申请实施例下文中的描述中,如果出现“主小 区”,在没有特别说明的情况下,该“主小区”指的是第一小区和第二小区中的主小区。相应的,如果出现“辅小区”,在没有特别说明的情况下,该“辅小区”指的是第一小区和第二小区中的辅小区。
需要说明的是,在该步骤中存在两种可能的场景,下面分别进行描述。
场景一,终端设备先在第一小区中确定第一小区的波束失败,并在确定第二小区的波束失败之前,已经发送第一小区的波束失败恢复请求,第一小区的波束失败请求信息用于指示第一小区的波束失败,或者用于请求恢复第一小区的波束。
场景一中的情况一:在第一小区是辅小区的情况下,终端设备可以中止或终止所述第一小区的波束失败恢复流程。此时,在该场景下,终端设备发送的第三信息可以至少用于指示主小区的波束失败。
需要说明的是,在第三信息只用于指示主小区的波束失败时,终端设备确定主小区的波束失败恢复成功后,在中止或终止所述第一小区的波束失败恢复流程的情况下,终端设备可以继续所述第一小区的波束失败恢复流程;在终止所述第一小区的波束失败恢复流程的情况下,终端设备可以重新发起所述第一小区的波束失败恢复流程。
场景一中的情况二:在第一小区是主小区的情况下,终端设备可以中止或终止所述第一小区的波束失败恢复流程。此时,在该场景下,终端设备发送的第三信息可以用于指示所述第一小区和所述第二小区的波束失败。
在该情况下,终端设备可以同时对所述第一小区和所述第二小区进行波束失败恢复。
当然,在该情况下,第三信息也可以只用于指示主小区的波束失败,本申请实施例对此并不限定。
场景二,终端设备确定第二小区的波束失败时,还未发送第一小区的波束失败请求信息,此时终端设备可以不再发送第一小区的波束失败请求信息。
需要说明的是,本申请实施例对第三信息中携带的内容并不限定,举例来说,第三信息可以包括以下任意一种或多种的组合:主小区的波束失败的原因;主小区的标识;辅小区的波束失败的原因;辅小区的标识;辅小区中新的可用波束的标识。
一种可能的实现方式中,当第三信息用于指示所述第一小区的波束失败,以及用于指示所述第二小区的波束失败时,所述终端设备可以通过第二资源向所述网络设备发送所述第三信息。

第二资源可以为所述网络设备为所述终端设备预配置的,也可以是网络设备为所述终端设备半静态激活的,也可以是网络设备为所述终端设备动态指示的,本申请实施例对此并不限定。
一种可能的实现方式中,当第三信息用于指示所述第一小区和第二小区中的主小区的波束失败时,所述终端设备可以通过随机接入时频资源向所述网络设备发送所述第三信息。
一种可能的实现方式中,当第三信息用于指示所述第一小区和第二小区中的辅小区的波束失败时,所述终端设备可以通过调度请求资源向所述网络设备发送所述第三信息。
步骤602:网络设备接收来自终端设备的第三信息。
步骤603:网络设备向终端设备发送第四信息。
其中,所述第四信息用于响应第三信息。举例来说,第三信息为BFRQ或者通过调度请求资源发送的调度请求(scheduling request,SR)时,第四信息可以为BFRR,其它情况不再赘述。
本申请实施例中,网络设备发送第四信息之后,网络设备还可以向终端设备指示辅小区中的新的可用波束,以及指示主小区中的新的可用波束。网络设备具体如何指示主小区中的新的可用波束,可以参考现有技术中的描述,本申请实施例在此不再赘述。

网络设备可以通过多种方式发送第五信息。第一种可能的实现方式中,网络设备可以在主小区中向终端设备发送第五信息。在该实现方式下,网络设备可以通过RRC信令,或者MAC-CE信令,或者DCI在主小区中发送第五信息。
其中,RRC信令和MAC-CE信令通过物理下行共享信道(physical downlink shared channel,PDSCH)承载;DCI通过物理下行控制信道(physical downlink control channel,PDCCH)承载。
在该实现方式下,第二波束可以为网络设备选择的波束,具体如何选择,本申请实施例对此并不限定。当然,第二波束也可以通过其他方式确定,在此不再逐一举例说明。
在该实现方式下,终端设备可以在主小区中接收来自网络设备的第五信息,并使用第二信息指示的第二波束,在辅小区中接收来自所述网络设备的下行信息。
第二种可能的实现方式中,网络设备可以在第三小区中向终端设备发送第五信息。第三小区为未发生波束失败的辅小区,第三小区为除了第一小区和第二小区之外的小区。
在该实现方式下,网络设备可以通过RRC信令,或者MAC-CE信令,或者DCI在第三小区中向终端设备发送第五信息。
同样的,在该实现方式下,第二波束可以为网络设备选择的波束,具体如何选择,本申请实施例对此并不限定。当然,第二波束也可以通过其他方式确定,在此不再逐一举例说明。
本申请实施例中,网络设备也可以隐式的向终端设备指示辅小区中的新的可用波束。在该实现方式下,终端设备发送的第三信息通过第二资源发送,所述第二资源与第二波束具有关联关系。网络设备接收到第三信息之后,使用第三信息关联的第二波束向终端设备发送下行数据。当终端设备通过第二波束接收到下行信息时,确定所述第二波束为所述终端设备在所述辅小区中新的可用波束。

另一种可能的实现方式中,终端设备发送第三信息所使用的第四波束,和第二波束存在关联关系。网络设备接收到第三信息之后,可以将与第四波束关联的波束作为第二波束。 其中,第四波束和第二波束的关联关系是预先配置的。
步骤604:终端设备接收来自网络设备的第四信息。
通过上面的流程,在确定第一小区的波束失败,在所述第一小区的波束失败恢复成功之前,如果确定第二小区的波束失败,则可以中止或终止所述第一小区的波束失败恢复流程,并至少恢复其中的主小区的波束,从而可以保证主小区恢复正常通信。进一步的,如果在恢复主小区的波束的同时,恢复其中的辅小区的波束,可以提高波束失败恢复效率,降低波束恢复的时延,提高辅小区的鲁棒性。
本申请实施例还提供一种波束失败的处理方法,下面详细描述。
参见图7,为本申请实施例提供的一种波束失败的处理方法流程示意图,该方法包括:
步骤701:终端设备确定第一小区的波束失败,在所述第一小区的波束失败恢复成功之前,若确定第二小区的波束失败,向网络设备发送第六信息。

图7所示的流程中,可以存在多种不同的场景,下面分别进行描述。

在场景一中,终端设备通过中止或终止辅小区的波束失败恢复流程,实现优先恢复主小区的波束失败,可以保证主小区优先恢复正常通信。
在场景一中,终端设备可以从预设的备选波束集合中选择一个波束作为第一波束,并通过所述第一波束,在与所述第一波束关联的随机接入资源中向所述网络设备发送所述第六信息。
当终端设备接收到来自网络设备的第七信息,可以确定主小区的波束失败恢复成功。
进一步的,在场景一中,主小区的波束失败恢复成功后,在中止所述第一小区的波束失败恢复流程的情况下,终端设备可以继续所述第一小区的波束失败恢复流程;在终止所述第一小区的波束失败恢复流程的情况下,终端设备可以重新发起所述第一小区的波束失败恢复流程。

场景二:第一小区是辅小区,第二小区是主小区,终端设备先在第一小区中确定第一小区的波束失败,并在确定第二小区的波束失败之前,还没有发送第一小区的波束失败恢复请求。
在场景二中,终端设备在第二小区的波束失败恢复之前,不再发送第一小区的波束失败恢复请求。此时,在该场景下,终端设备发送的第六信息可以用于指示主小区的波束失败。终端设备具体如何发送第六信息,可以参考场景一中的描述,在此不再赘述。
在场景二中,终端设备通过不执行辅小区的波束失败恢复流程,实现优先恢复主小区的波束失败,可以保证主小区优先恢复正常通信。
进一步的,在场景二中,主小区的波束失败恢复成功后,终端设备可以执行所述第一小区的波束失败恢复流程,实现恢复所述第一小区的波束失败。

场景四:第一小区是辅小区,第二小区是主小区;或者,第一小区是主小区,第二小区是辅小区。
在场景四中,终端设备先在第一小区中确定第一小区的波束失败,并在确定第二小区的波束失败之前,无论是否已经发送第一小区的波束失败恢复请求,终端设备可以终止所述第一小区的波束失败恢复流程。此时,在该场景下,终端设备发送的第六信息可以用于指示主小区的波束失败以及用于指示辅小区的波束失败。
在场景四中,终端设备通过第六信息同时执行主小区与辅小区的波束失败恢复流程,可以保证主小区与辅小区同时恢复正常通信。

本申请实施例中,网络设备发送第七信息之后,网络设备还可以向终端设备指示辅小区中的新的可用波束,以及指示主小区中的新的可用波束。网络设备具体如何指示主小区中的新的可用波束,可以参考现有技术中的描述,本申请实施例在此不再赘述。
网络设备可以显式的向终端设备指示辅小区中的新的可用波束。具体的,网络设备可以向终端设备发送第九信息,第九信息用于指示第五波束。其中,第五波束是终端设备在 辅小区中新的可用波束,终端设备可以在所述辅小区中使用所述第五波束接收来自所述网络设备的下行信息。
网络设备可以通过多种方式发送第九信息。第一种可能的实现方式中,网络设备可以在主小区中向终端设备发送第九信息。在该实现方式下,网络设备可以通过RRC信令,或者MAC-CE信令,或者DCI在主小区中发送第五信息。
在该实现方式下,第五波束可以为网络设备选择的波束,具体如何选择,本申请实施例对此并不限定。当然,第五波束也可以通过其他方式确定,在此不再逐一举例说明。
