Description
本公开涉及通信技术领域,尤其涉及一种波束故障恢复请求发送方法、响应方法、装置及存储介质。
在NR(New Radio,新空口)技术中,波束故障恢复流程包括四个步骤:第一步,波束故障探测。基站显示或隐式地配置一个波束故障探测参考信号集合,UE(User Equipment,用户设备)监听该集合内的所有波束,如果这些波束都出现了故障,则认为出现了波束故障。第二步,候选波束识别。基站显示地配置一个候选波束参考信号集合,UE监听该集合内的所有波束,如果发现至少有一个波束的质量高于预配置的门限值,则认为发现了新的候选波束。第三步,BFRQ(Beam Failure Recovery Request,波束故障恢复请求)传输。当第一步和第二步都成立后,UE传输BFRQ给基站,以便将波束故障事件以及发现的可用的候选波束信息告知基站。第四步,UE监听基站对BFRQ的响应。
目前,可通过PRACH(Physical Random Access Channel,物理随机接入信道)用于BFRQ的传输。但由于PRACH资源的周期较长,导致传输BFRQ的周期长、时延大。

这里将详细地对示例性实施例进行说明,其示例表示在附图中。下面的描述涉及附图时,除非另有表示,不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反,它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
图1是根据一示例性实施例示出的一种波束故障恢复请求发送方法的流程图,该方法应用于终端,即该方法可由终端执行,如图1所示,该方法包括:
步骤101:在终端发生波束故障事件后,查找候选波束。
在一种可实现方式中,终端查找的候选波束为当前可用的候选波束。
步骤102:在查找到至少一个候选波束后,使用PUCCH(Physical Uplink Control CHannel,物理上行链路控制信道)资源向基站发送BFRQ,其中,PUCCH资源包括基站预先为终端分配的PUCCH资源或者预设格式的PUCCH资源。
在一种可实现方式中,BFRQ至少可包括波束故障事件,还可包括终端选择的候选波束的索引。
在一种可实现方式中,基站可以通过RRC(Radio Resource Control,无线资源控制)信令、MAC(Medium/Media Access Control,媒体访问控制)CE(控制元素)或物理层信令半静态地或动态地为终端配置用于传输BFRQ的PUCCH资源。
在一种可实现方式中,基站预先为终端分配的用于传输BFRQ的PUCCH资源可包括SR(Scheduling Request,调度请求)资源。
在一种可实现方式中,终端在发生波束故障事件后,可以在查找到一个候选波束后,使用PUCCH资源向基站发送BFRQ,还可以是查找到多个候选波束后,使用PUCCH资源向基站发送BFRQ。
在一种可实现方式中,在步骤102之后,终端可监听基站对BFRQ的响应消息,在监听到该响应消息后,接收该响应消息。
本公开的实施例的波束故障恢复请求发送方法,在终端发生波束故障并查找到候选波束后,使用基站预先为终端分配的PUCCH资源或使用预设格式的PUCCH资源向基站发送BFRQ,实现了使用PUCCH资源传输BFRQ的目的,使得传输BFRQ的时延较小,也使得基站可及时获知发生波束故障的终端以及该终端的候选波束,便于基站及时进行波束故障恢复流程。
图2是根据一示例性实施例示出的一种波束故障恢复请求发送方法的流程图,如图2所示,该方法在步骤101以及步骤102的基础上,还可包括:在步骤103中,接收基站发送的第一控制信令,该第一控制信令中指示了为终端分配的用于发送BFRQ的PUCCH资源,该PUCCH资源可包括时域资源、频域资源或码域资源中的至少一种,基站可以通过RRC信令、MAC CE或物理层信令半静态地或动态地为终端配置用于传输BFRQ的PUCCH资源。本实施例并不限定步骤103与步骤101、步骤102执行的先后顺序,图2仅示出了步骤103在步骤101以及步骤102之前执行的一种情况。
在一种可实现方式中,基站向终端发送的第一控制信令中还可以指示了PUCCH资源与终端的标识以及终端的候选波束的索引之间的对应关系,例如,在该第一控制信令中指示各PUCCH资源分别与某一终端的某一个候选波束对应。此外,该对应关系还可以是基站预先与终端约定好的,例如,该对应关系可以是协议中规定的。基于该对应关系,终端在要向基站发送BFRQ时,可根据自身的标识查找到基站为其分配的用于传输BFRQ的PUCCH资源。图3是根据一示例性实施例示出的一种波束故障恢复请求发送方法的流程图,在该方法中,使用PUCCH资源向基站发送BFRQ可包括:在步骤1021中,使用与终端的标识对应且与终端的候选波束的索引对应的PUCCH资源向基站发送BFRQ。基于此,基站在接收到该BFRQ后,即可根据候选波束的索引与PUCCH资源的对应关系获知终端的候选波束的索引,在该种情况下,终端在向基站发送BFRQ时,则无需在BFRQ中携带候选波束的信 息,而基站在接收到BFRQ后,基于发送该BFRQ的PUCCH资源与终端的标识之间的对应关系,可确定终端的标识,从而确定出该标识所标识的终端为发生波束故障的终端,还可确定出与该PUCCH资源对应的候选波束的索引,进而可根据该索引确定出发生波束故障的终端的候选波束。
在一种可实现方式中,基站向终端发送的第一控制信令中还可指示了PUCCH资源与终端的标识之间的对应关系,该对应关系还可以是基站预先与终端约定的,例如,该对应关系可以是协议中规定的。基于该对应关系,终端在要向基站发送BFRQ时,可根据自身标识查找基站为其分配的用于传输BFRQ的PUCCH资源。图4是根据一示例性实施例示出的一种波束故障恢复请求发送方法的流程图,如图4所示,在该方法中,使用PUCCH资源向基站发送BFRQ可包括:在步骤1022中,使用与终端的标识对应的PUCCH资源向基站发送BFRQ。基于此,基站在接收到BFRQ后,根据发送该BFRQ的PUCCH资源与终端的标识之间的对应关系可确定终端的标识,从而确定该标识所标识的终端为发生波束故障的终端。
图5是根据一示例性实施例示出的一种波束故障恢复请求发送方法的流程图,如图5所示,该方法在包括步骤101以及步骤102的基础上,还可包括:在步骤104中,接收基站发送的第二控制信令,该第二控制信令中指示了免授权传输资源池(也称grant free传输资源池,或免调度传输资源池),该资源池可以是基站为该终端分配的免授权传输资源池,还可以是基站为多个终端分配的免授权传输资源池。在终端有数据需要传输时,即可使用该资源池内的传输资源进行传输。第二控制信令例如RRC信令,基站可通过RRC信令半静态地为终端配置该传输资源池,该传输资源池中的传输资源可包括时域资源以及码域资源;在步骤105中,在向基站发送BFRQ时,或向基站发送BFRQ之后,使用免授权传输资源池中的传输资源向基站发送PUSCH(Physical Uplink Shared Channel,物理上行共享信道)消息,其中,PUSCH消息中包括终端的标识以及终端选择的候选波束的索引。需要说明的是,步骤104以及步骤105可发生在步骤101以及步骤102之前,还可发生在步骤101以及步骤102之后,图5仅示出了步骤104以及步骤105发生在步骤101以及步骤102之后的一种情况。在终端查找到一个候选波束即向基站发送BFRQ时,PUSCH消息中的候选波束的索引即为终端查找到的候选波束的索引,在终端查找到多个候选波束后再向基站发送BFRQ时,PUSCH消息中的候选波束的索引为终端从查找到的多个候选波束中选择的一个候选波束的索引。基站接收到该PUSCH消息后,可将PUSCH消息中的候选波束的索引对应的候选波束确定为终端的候选波束。基站还可根据PUSCH消息中的终端的标识来确定发生波束故障的终端。
在一种可实现方式中,波束故障恢复请求发送方法可包括:终端使用基站为其配置的PUCCH资源向基站上报波束故障事件,使用基站为其配置的免调度传输资源池中的传输资源向基站上报终端选择的一个候选波束的索引。以下结合图6,通过一个例子对该方法进行说明。如图6所示,在该例子中,基站通过RRC信令半静态地为终端配置用于传输BFRQ的SR资源,其中不同的UE(同终端)ID(标识)对应不同的时域资源和/或频域资源,除此之外,基站还通过RRC信令半静态地为UE配置一个grant free传输资源池。当UE发现波束故障事件并找到一个可用的候选波束后,UE根据自身的UE ID找到对应的SR资源传输BFRQ,该BFRQ可仅用于告知基站UE出现了波束故障事件。当UE在SR资源上发送BFRQ后,UE将在grant free传输资源池上发送PUSCH消息给基站,该PUSCH消息中可包括UE ID以及UE所选择的候选波束的索引。基站盲检SR,当接收到通过SR资源传输的BFRQ,发现某一个UE出现波束故障后,在grant free资源池上接收UE发送的PUSCH消息,当根据PUSCH消息识别出出现波束故障的UE以及其上报的候选波束的索引之后,基站可执行后续的波束故障恢复流程。
基于一种可实现方式,本公开还提供了一种波束故障恢复请求发送方法,该方法与图5所示的方法大致相同,其不同之处在于,在该方法中,PUSCH消息中包括终端的标识以及终端选择的至少一个 候选波束的索引,以及至少一个候选波束中每个候选波束的质量信息,该方法与图5所示的方法相同之处可参考上述对图5的所示的方法的描述。该方法在包括步骤101以及步骤102的基础上还可包括,接收基站发送的第二控制信令,第二控制信令中指示了免授权传输资源池;在向基站发送BFRQ时,或向基站发送BFRQ之后,使用免授权传输资源池中的传输资源向基站发送PUSCH消息,该PUSCH消息中包括终端的标识以及终端选择的至少一个候选波束的索引,以及至少一个候选波束中每个候选波束的质量信息,该质量信息例如候选波束对应的L1-RSRP(在物理层上测量出的RSRP(Reference Signal Receiving Power,参考信号接收功率))。
在一种可实现方式中,波束故障恢复请求发送方法可包括:终端使用基站为其配置的PUCCH资源向基站上报波束故障事件,使用基站为其配置的免调度传输资源池中的传输资源向基站上报终端选择的多个候选波束的质量信息,以下通过一个例子对该方法进行说明。在该例子中,基站通过RRC信令半静态地为UE配置用于传输BFRQ的SR资源,可包括时域资源和/或频域资源,不同的UE ID对应不同的时域资源和/或频域资源,除此之外,基站还通过RRC信令半静态地为UE配置一个grant free传输资源池。当UE发现波束故障事件并找到可用的候选波束后,UE根据自身的UE ID找到对应的SR资源传输BFRQ,该BFRQ可只用于告知基站UE出现了波束故障事件。当UE在SR资源上发送BFRQ后,UE将在grant free传输资源池上传输PUSCH,其中PUSCH上包括UE ID以及UE所选择的候选波束的具体信息,例如包括每一个候选波束所对应的L1-RSRP等。基站盲检SR,当发现某一个UE出现波束故障后,在grant free资源池上接收UE上报的候选波束的信息。当识别出出现波束故障的UE以及其上报的候选波束信息后,基站开始执行后续的波束故障恢复流程。
在终端使用免调度传输资源池中的传输资源向基站发送消息时,一方面由于基站不知道终端何时发送消息,可能会导致对终端消息的漏检;另一方面由于多个终端可能同时在一个资源上发送消息,基站可能不能正确解码终端发送的消息,为了确保终端发送的消息能够被基站正确解码,终端在使用免调度传输资源池中的传输资源发送PUSCH消息时可重复发送多次。如图7所示,使用免授权传输资源池中的传输资源向基站发送PUSCH消息还可包括:在步骤1051中,使用免授权传输资源池中的传输资源重复向基站发送PUSCH消息,直到发送PUSCH消息的次数达到阈值或接收到基站对PUSCH消息的反馈消息。该阈值可由终端与基站预先约定,还可以由基站为终端配置该阈值。
在一种可实现方式中,预设格式的PUCCH资源可包括:可携带多个比特的PUCCH格式的PUCCH资源,在使用该预设格式的PUCCH资源向基站发送BFRQ时,终端向基站发送的BFRQ中包括:终端选择的至少一个候选波束的索引以及该至少一个候选波束中每个候选波束的质量信息,该质量信息例如L1-RSRP。由于每个终端的PUCCH传输资源不同,因此基站在接收到终端发送的BFRQ后,可根据PUCCH资源获得终端的标识,从而确定发生波束故障的终端。其中,预设格式的PUCCH资源例如相关技术中用于上报候选波束的PUCCH格式的PUCCH资源,为了对用于传输BFRQ的PUCCH与用于上报候选波束的PUCCH进行区分,可在用于传输BFRQ的PUCCH资源的PUCCH格式中定义一个flag(标志位),例如定义一个1比特的标志位,使用该标志位来标识用于传输BFRQ的PUCCH资源。
图8是根据一示例性实施例示出的一种波束故障恢复请求响应方法的流程图,该方法应用于基站,即该方法可由基站执行,如图8所示,该方法包括:
步骤701:接收基于PUCCH资源传输的BFRQ,该PUCCH资源为基站预先为终端分配的PUCCH资源或者为预设格式的PUCCH资源。
在一种可实现方式中,基站可以通过RRC信令、MAC CE或物理层信令半静态地或动态地为终端配置用于传输BFRQ的PUCCH资源,而预设格式的PUCCH资源可以包括可携带多个比特的PUCCH资源,使得基站可及时获知发生波束故障的终端以及该终端的候选波束,便于基站及时进行波束故障 恢复流程。
在一种可实现方式中,基站预先为终端分配的PUCCH资源可包括SR资源。
在一种可实现方式中,基站可通过对来自终端的PUCCH消息进行盲检,确定PUCCH消息的内容是否包括BFRQ来获取到终端发送的BFRQ。
步骤702:确定发生波束故障的终端以及终端的候选波束。
在一种可实现方式中,基站可基于发送BFRQ的PUCCH资源来确定发生波束故障的终端,还可基于BFRQ中的终端标识来确定发生故障的终端。
步骤703:通过候选波束向终端发送对BFRQ的响应消息。
通过本公开的实施例的波束故障恢复请求响应方法,基站接收终端通过基站预先为其分配的PUCCH资源或预设格式的PUCCH资源传输的BFRQ,实现了通过PUCCH资源传输BFRQ的目的,使得传输BFRQ的时延较小。
图9是根据一示例性实施例示出的一种波束故障恢复请求响应方法的流程图,如图9所示,该方法在步骤701至步骤703的基础上还可包括:在步骤704中,向至少一个终端发送第一控制信令,该第一控制信令中指示了为至少一个终端分配的用于发送BFRQ的PUCCH资源。本实施例不对步骤704与步骤701至步骤703之间的执行顺序进行限定,图9仅示出了步骤704在步骤701之前执行的一种情况。该PUCCH资源可包括时域资源、频域资源或码域资源等,基站可以通过RRC信令、MAC CE或物理层信令半静态地或动态地为终端配置用于传输BFRQ的PUCCH资源。例如,当为终端分配的用于发送BFRQ的PUCCH资源为SR资源时,基站可以通过RRC信令半静态地为终端配置用于传输BFRQ的SR资源,包括时频域资源等,其中,每一个SR资源可与某一个终端的某一个候选波束的索引一一对应,如图10所示,SR资源A与编号为1的候选波束以及标识为1的UE对应,SR资源B与编号为2的候选波束以及标识为1的UE对应。
在一种可实现方式中,第一控制信令中还可指示了终端的标识与PUCCH资源以及终端的候选波束之间的对应关系,例如,在该第一控制信令中指示了各PUCCH资源与某一终端的某一个候选波束对应,此外,该对应关系还可以是基站预先与终端约定的。图11是根据一示例性实施例示出的一种波束故障恢复请求响应方法的流程图,如图11所示,确定发生波束故障的终端以及终端的候选波束可包括:在步骤7021中,确定与传输BFRQ的PUCCH资源对应的标识所标识的终端为发生波束故障的终端;传输BFRQ的PUCCH资源即为基站通过第一控制信令为终端分配的用于传输BFRQ的PUCCH资源中的一者,基站根据该PUCCH资源与终端的标识的对应关系可获知终端的标识,从而确定该标识所标识的终端即为发生波束故障的终端。在步骤7022中,确定与传输BFRQ的PUCCH资源对应且与终端的标识对应的候选波束的索引;在步骤7023中,根据候选波束的索引确定终端的候选波束。
在一种可实现方式中,第一控制信令中还可指示了终端的标识与PUCCH资源的对应关系,例如,该第一控制信令中可包括一个终端的标识与多个PUCCH资源的对应关系,该第一信令中还可包括多个终端的标识分别与多个PUCCH资源的对应关系。确定发生波束故障的终端可包括:确定与传输BFRQ的PUCCH资源对应的标识所标识的终端为发生波束故障的终端。本实施例的方法与图11所示的方法的不同之处在于,第一控制信令中并未指示终端的候选波束与终端的标识以及PUCCH资源的对应关系,故,在本实施例的方法中,在终端向基站发送BFRQ之后,终端还可向基站上报其自身的候选波束,基站根据终端上报的内容来获知终端的候选波束。
图12是根据一示例性实施例示出的一种波束故障恢复请求响应方法的流程图,如图12所示,该方法在步骤701至步骤703的基础上还可包括:在步骤705中,向终端发送第二控制信令,该第二控制信令中指示了免授权传输资源池;该第二控制信令例如RRC信令,基站可通过RRC信令半静态地为终端配置该传输资源池,该传输资源池中包括的传输资源可包括时域资源以及频域资源;在步骤706 中,在免授权传输资源池中的传输资源上接收终端发送的PUSCH消息,其中,PUSCH消息中包括终端的标识以及终端选择的候选波束的索引,通过步骤705以及步骤706即可实现终端向基站上报其候选波束的目的。此处的PUSCH消息可参考上述对图5所示的方法中对PUSCH消息的描述。需要说明的是,步骤706可以与步骤701同时执行,也可在步骤701之后执行,图12仅示出了步骤706在步骤701之后执行的一种情况。
图13是根据一示例性实施例示出的一种波束故障恢复请求响应方法的流程图,如图13所示,在该方法中,确定发生波束故障的终端以及终端的候选波束可包括:在步骤7025中,确定PUSCH消息中的标识所标识的终端为发生波束故障的终端;在步骤7026中,根据PUSCH消息中的候选波束的索引确定终端的候选波束。在该方法中,基站在接收PUSCH消息的同时,或接收到该PUSCH消息之前,接收终端上报的BFRQ,该BFRQ中可仅包括波束故障事件的信息。基站结合接收到的BFRQ以及PUSCH消息,即可确定发生波束故障的终端以及该终端对应的候选波束。
本公开还提供了另一种波束故障恢复请求响应方法,该方法与图12所示的方法的不同之处在于,在该方法中,PUSCH消息中包括终端的标识以及终端选择的至少一个候选波束的索引,以及该至少一个候选波束中每个候选波束的质量信息,该方法与图12所示的方法相同之处可参考上述对图12的所示的方法的描述。该方法在步骤701至703的基础上还可包括:向终端发送第二控制信令,该第二控制信令中指示了免授权传输资源池;在免授权传输资源池中的传输资源上接收终端发送的PUSCH消息,该PUSCH消息中包括终端的标识以及终端选择的至少一个候选波束的索引,以及该至少一个候选波束中每个候选波束的质量信息,该质量信息例如候选波束所对应的L1-RSRP。基站在接收到该PUSCH消息后,可根据各候选波束的质量信息以基站预设的筛选规则选择PUSCH消息中所指示的一个候选波束作为终端的候选波束。
关于上述实施例中的装置,其中各个模块执行操作的具体方式已经在有关该方法的实施例中进行了详细描述,此处将不做详细阐述说明。
图14是根据一示例性实施例示出的一种波束故障恢复请求发送装置的框图,该装置应用于终端,如图14所示,该装置150包括:查找模块151,用于在终端发生波束故障事件后,查找候选波束;第一发送模块152,用于在查找到至少一个候选波束后,使用PUCCH资源向基站发送BFRQ,PUCCH资源包括基站预先为终端分配的PUCCH资源或者预设格式的PUCCH资源。
图15是根据一示例性实施例示出的一种波束故障恢复请求发送装置的框图,如图15所示,该装置160在装置150的基础上还可包括:第一接收模块153,用于接收基站发送的第一控制信令,第一控制信令中指示了为终端分配的用于发送BFRQ的PUCCH资源。
在一种可实现方式中,第一控制信令中还可指示了PUCCH资源与终端的标识以及终端的候选波束的索引之间的对应关系,基于此,发送模块可用于:使用与终端的标识对应且与终端的候选波束的索引对应的PUCCH资源向基站发送BFRQ。
