具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
参见图1，图1是本公开实施例提供的波束恢复处理方法的流程图，如图1所示，包括以下步骤。
步骤101，若满足预设触发条件，网络侧设备向移动终端发送第一指示消息，所述第一指示消息用于指示新的波束对链接BPL；所述预设触发条件为所述移动终端根据下行参考信号的测量结果确定启动波束恢复机制或所述网络侧设备根据上行参考信号测量结果确定启动波束恢复机制。
本公开实施例提供的波束恢复处理方法主要应用在无线通信系统中，用于判断无线链路是否传输质量变差，并进行波束的恢复处理。
可以理解的是，上述网络侧设备(也可称为MF接入设备)可以是基站，当然可以理解的是，上述基站的形式不限，可以是宏基站(Macro Base Station)、微基站(Pico Base Station)、Node B(3G移动基站的称呼)、增强型基站(ENB)、家庭增强型基站(Femto eNB或Home eNode B或Home eNB或HNEB)、中继站、接入点、RRU(Remote Radio Unit，远端射频模块)、RRH(Remote Radio Head，射频拉远头)等。
具体的，本实施例中，可以根据上行参考信号或下行参考信号的测量结果，确定无线链路是否传输质量变差，从而确定是否启动波束恢复机制。当 无线链路传输质量变差时，确定启动波束恢复机制，当无线链路成功时，确定无需启动波束恢复机制。
上述上行参考信号可以包括：上行业务信道的解调参考信号DMRS(De Modulation Reference Signal)和/或信道探测参考信号SRS(Sounding Reference Signal)等。
上述下行参考信号可以包括：下行业务信道的解调参考信号DMRS(De Modulation Reference Signal)和/或信道状态信息参考信号CSI-RS(Channel State Information-Reference Signal)等。
在本实施例中，网络侧设备可以直接对上行参考信号进行测量，从而监控波束质量，确定是否启动波束恢复机制。此外还可以由移动终端对下行参考信号进行测量，从而监控波束质量，并将监测的结果发送至网络侧设备，指示网络侧设备启动波束恢复机制。
无论是网络侧设备确定启动波束恢复机制，还是移动终端确定启动波束恢复机制，均会触发网络侧设备向移动终端发送第一指示消息，通过该第一指示消息指示新的BPL(Beam pair link)。应理解，指示新的BPL的数量可以根据实际需要进行设置，例如可以为一个BPL，也可以为多个PBL组成的PBL组。
步骤102，切换至所述新的BPL进行数据传输。
该步骤中，网络侧设备在发送完第一指示消息后，将会切换BPL，与此同时移动终端在接收上述第一指示消息后，将会根据第一指示消息所指示的BPL切换BPL，从而在新的BPL上进行数据传输。
这样，本公开实施例中，若满足预设触发条件，网络侧设备向移动终端发送第一指示消息，所述第一指示消息用于指示新的波束对链接BPL；所述预设触发条件为所述移动终端根据下行参考信号的测量结果确定启动波束恢复机制或所述网络侧设备根据上行参考信号测量结果确定启动波束恢复机制；切换至所述新的BPL进行数据传输。由于对上行参考信号或下行参考信号进行测量确定链路状态，并当链路传输质量变差需要启动波束恢复机制时，网络侧设备向移动终端发送第一指示信息，从而将移动终端和网络侧设备切换至新的BPL上进行数据传输，相对于相关技术通过高层监测链路状态，并发 起RRC重建，再进行波束训练，找到最优波束，恢复数据传输，本公开降低了波束恢复的时延。
应当说明的是，对于链路状态的监测可以由移动终端进行，也可以由网络侧设备进行。以下将以两种不同的实施方式进行详细说明：
在一实施方式中，若由网络侧设备根据上行参考信号的测量结果，确定是否启动波束恢复机制，则可以参照图2，图2是本公开实施例提供的波束恢复处理方法的流程图，如图2所示，上述步骤101之前，所述方法还包括：
步骤103，测量上行参考信号的第一测量指标。
该步骤中，上述第一测量指标的具体参数可以根据实际需要进行设置，例如本实施例中，上述第一测量指标包括参考信号接收功率RSRP(Reference Signal Receiving Power)、小区参考信号功率相对小区所有信号功率的比值RSRQ(Reference Signal Receiving Quality)、信噪比SNR(SIGNAL-NOISE RATIO)、信道质量指示CQI(Channel Quality Indicator)和传输混合自动重传请求的确认信息NACK中的至少一项。
在本实施例中，网络侧设备可以根据上述第一测量指标对上行参考信号进行测量，获得相应的结果。
步骤104，若所述上行参考信号的第一测量指标满足第一预设条件，则确定满足预设触发条件。
该步骤中，上述第一预设条件的内容可以根据实际需要进行设置。本实施例中，当所述第一测量指标包括参考信号接收功率RSRP、小区参考信号功率相对小区所有信号功率的比值RSRQ、信噪比SNR和信道质量指示CQI中的至少一项时，所述第一预设条件包括：在预设时间段内所述第一测量指标低于对应的预设门限值的次数大于第一预设值；当所述第一测量指标包括传输混合自动重传请求的确认信息NACK时，所述第一预设条件还包括：在所述预设时间段内产生所述NACK的次数大于所述第一预设值。
具体的，上述门限值的大小可以根据实际需要进行设置，且第一测量指标不同的参数对应的门限值的大小可以不同。应理解，在其他实施例中，上述第一预设条件还可以设置为在预设时间段内所述第一测量指标的具体参数的累计值的平均值是否低于对应的门限值，若是，则认为波束质量变差，确 定需要启动波束恢复机制。
当第一测量指标设置有多个参数时，可以是一个参数满足对应的第一预设条件，即可以确定需要启动波束恢复机制；也可以是所有的参数满足对应的第一预设条件，才可以确定需要启动波束恢复机制。此外，还可以是每当第一测量指标的一个参数满足对应的第一预设条件时，计数器加1，判断计数器的值是否大于第一预设值等方式均可实现，在此不再一一赘述。
本实施例中，可以灵活设置上述第一预设值的大小，提高波束质量变差的准确性和灵活性。
上述NACK指标用于业务信道的波束测量指标，是指终端接收下行业务信道PDSCH(Physical Downlink Shared Channel，物理下行共享信道)并解码错误，产生用于反馈给网络侧设备的HARQ信令NACK，来标识本次传输错误。每当产生一个NACK，可以控制计数器加1，判断在预设的时间段内计数器的值是否大于第一预设值，即可确定是否需要启动波束恢复机制。
在另一实施方式中，若由移动终端根据下行参考信号的测量结果，确定是否启动波束恢复机制，则可以参照图3，图3是本公开实施例提供的波束恢复处理方法的流程图，如图3所示，上述步骤101包括：步骤105，接收移动终端根据下行参考信号的第二测量指标的测量结果，向所述网络侧设备发送的目标数据。
该步骤中，上述第二测量指标的具体参数可以根据实际需要进行设置，例如本实施例中，上述第二测量指标包括参考信号接收功率RSRP、小区参考信号功率相对小区所有信号功率的比值RSRQ、信噪比SNR、信道质量指示CQI和传输混合自动重传请求的确认信息NACK中的至少一项。
在本实施例中，移动终端可以根据上述第二测量指标对下行参考信号进行测量，获得相应的结果，并根据测量的结果发送相应的目标数据，从而由网络侧设备根据该目标数据启动波束恢复机制。
步骤106，根据所述目标数据确定是否满足预设触发条件。
该步骤中，上述目标数据上报的方式可以根据实际需要进行设置。此外上述目标数据的内容也可以根据实际需要进行设置，例如，可以是直接告知网络侧设备启动波束恢复机制的消息，也可以是隐含告知网络侧设备是否启 动波束恢复机制的消息。以下对此进行详细说明：
在一实施例中，移动终端可以通过物理随机接入信道PRACH的随机接入前导码preamble进行上报，即上述目标数据可以为物理随机接入信道PRACH的随机接入前导码preamble。为了与传统随机接入过程中的preamble相区别，可以设计为新的type，例如新的时频发送图样等。即根据某种规则向基站进行不同空间方向的轮流波束发射。
具体的，移动终端向基站发送PRACH preamble，可以是beam sweeping的方式如：以原BPL的方向为中心，与该方向由相近到远离的顺序依次发射上行波束；或者与该方向由远离到相近的顺序依次发射上行波束；或者与该方向的相近和远离方向的某个跳变顺序来依次发射上行波束。
在另一实施例中，移动终端可以向网络侧设备发送request，即上述目标数据可以为移动终端向网络侧设备发送的request消息。
在一些可选的实施例中，在所述request消息携带指示启动波束恢复机制的第一信令和/或指示启动波束恢复机制所使用的BPL的第二信令；或者，所述preamble携带所述第一信令和/或所述第二信令。例如，所述第一信令中通过1个数据位bit指示是否启动波束恢复。所述第二信令中通过预设数量的数据位bit指示所述移动终端监测获得的启动波束恢复机制所使用的BPL。
应当说明的是，启动波束恢复机制所使用的BPL可以是一个，也可以是多个(即BPL组)。本实施例中，指示所述移动终端监测获得的启动波束恢复机制所使用的BPL可以为移动终端检测到的最优的BPL，也可以是移动终端从最优的BPL中推荐的BPL，具体地，移动终端上报的BPL可以与网络侧设备当前使用的最优BPL保持不变，也可以更改为其他BPL，在此不做进一步的限定。
具体的，当采用request消息发送到网络侧设备，并由网络侧设备根据request消息确定是否启动波束恢复机制时，request消息的发送方式可以根据实际需要进行设置，例如上述request消息在上行控制信道上承载发送，或者使用宽波束发送，或者使用多个窄波束同时发送。
进一步，在进行波束质量监测前，移动终端均需要进行接入无线网络，即接入网络侧设备提供的无线网络，建立BPL。具体的，参照图4，上述波 束恢复处理方法包括：
步骤401，向通过随机接入过程接入到网络侧设备的移动终端发送波束测量上报配置。
步骤402，接收所述移动终端基于所述波束测量上报配置进行波束训练所上报的结果。
步骤403，根据上报的结果确定最优的BPL进行数据传输。
步骤404，若满足预设触发条件，网络侧设备向移动终端发送第一指示消息，所述第一指示消息用于指示新的波束对链接BPL；所述预设触发条件为所述移动终端根据下行参考信号的测量结果确定启动波束恢复机制或所述网络侧设备根据上行参考信号测量结果确定启动波束恢复机制。
步骤405，切换至所述新的BPL进行数据传输。
本实施例中，上述最优的BPL即为发射波束Tx beam和接收波束Rx beam的方向对齐，获得最优的数据传输质量。找到最优BPL可以是多个，BPL来自相同或者不同的TRP(Transmission and Reception Point发送接收点)。这里不限制多个TRP是否归属于同一个基站。TRP对于BPL的维护以及使用，可以通过基站来进行控制或交互。
也就是说，在本实施例中，所述最优的BPL包括一个或多个目标BPL。其中每一目标BPL的可以有一套或者两套BPL，即每一所述目标BPL包括针对控制信道传输的控制信道BPL和/或针对业务信道传输的业务信道BPL；其中所有的所述目标BPL包括至少一个所述控制信道BPL和至少一个业务信道BPL。
具体的，针对控制信道传输的控制信道BPL通常采用宽波束发送，也可以采用多个窄波束联合发送。业务信道BPL通常采用一个窄波束发送，对此还可以采用多个窄波束进行联合发送。也就是说在本实施例中，所述多个目标BPL进行数据传输的方式包括：相同的信息并且使用相同的时频资源、频分复用FDM、时分复用TDM和码分复用CDM的传输方式中的至少一项。
进一步的，对于指示的新的波束对链接BPL中的内容可以根据实际需要进行设置，例如，在一实施例中，所述指示新的波束对链接BPL包括：指示新的业务信道BPL。在另一实施例中，所述指示新的波束对链接BPL还包括： 指示新的控制信道BPL。
此外，在指示新的业务信道BPL前，还可以对窄波束进行测量，确定最优的BPL，从而提高业务信道BPL传输的质量。参照图5所示，上述波束恢复处理方法包括：
步骤501，若满足预设触发条件，网络侧设备向所述移动终端发送第二指示消息，所述第二指示消息用于指示启动局部波束训练，所述局部波束训练为最优控制信道BPL内，进行窄波束训练。
步骤502，接收所述移动终端对所述窄波束训练所反馈的波束测量结果。
步骤503，根据所述波束测量结果确定最优窄波束，并将所述最优窄波束设定为所述新的业务信道BPL。
步骤504，向移动终端发送第一指示消息，所述第一指示消息用于指示新的波束对链接BPL；所述预设触发条件为所述移动终端根据下行参考信号的测量结果确定启动波束恢复机制或所述网络侧设备根据上行参考信号测量结果确定启动波束恢复机制。
步骤505，切换至所述新的BPL进行数据传输。
本实施例中，可以对最优的控制信道BPL内的窄波束进行波束训练，从而确定出最优的窄波束，将最优的窄波束指示为新的业务信道BPL，从而提高了业务信道BPL传输的质量。
针对不同的业务信道BPL和控制信道BPL的传输情况以及波束恢复情况，以下将以不同的实例进行阐述。
在建立BPL后，找到的最优BPL可以为多个，且多个BPL来自不同的TRP，该BPL具有两套，包括控制信道BPL和业务信道BPL。
如图6所示，两个TRP和移动终端之间分别建立了宽BPL(即控制信道BPL)和窄BPL(即业务信道BPL)。在宽BPL上可以发送相同的信息内容，从而在一个宽BPL被阻挡时，另一个BPL仍然可以正常使用。
如图7所示，业务信道的窄BPL被阻挡，但控制信道的宽BPL仍然能够连接，如图8所示，业务信道的窄BPL和控制信道的宽BPL均被阻挡。此时，移动终端上报request消息或发送preamble时，除了携带指示启动波束恢复机制的第一信令(如1bit指示启动)，还可以携带最优的PDCCH(Physical  Downlink Control Channel，物理下行控制信道)BPL和/或PDSCH BPL的第二信令。即，如果当前宽BPL质量仍然可以进行传输，可以继续使用。如果当前宽BPL虽然未中断但质量很差，或者当前宽BPL被阻挡了，那么此时request消息中要携带使用其他的新BPL的消息。
网络侧设备根据移动终端反馈的request消息，要向移动终端指示新的PDCCH波束和/或新的PDSCH波束。其中，新的PDCCH的波束可以是原来的宽BPL或者新的宽BPL；新的PDSCH波束可以是原来宽BPL中的其它窄BPL，或者新的宽BPL中的窄BPL。
此外，网络侧设备还可以向移动终端指示启动局部波束训练，例如在网络侧设备指示的宽BPL内，共包含3个窄波束，则对着3个窄波束进行轮流发射，即局部波束训练。移动终端接收后反馈最优的窄波束，从而确定在宽BPL内的新的窄BPL。本实施例中，通过网络侧设备的指示，从而确定最终的新BPL，能够更加快速和准确。
参照图9，图9是本公开实施例提供的波束恢复处理方法的流程图，如图9所示，该波束恢复处理方法，包括以下步骤。
步骤901，移动终端接收网络侧设备所发送的第一指示消息，所述第一指示消息为网络侧设备满足预设触发条件时向所述移动终端发送的消息；所述第一指示消息用于指示新的波束对链接BPL；所述预设触发条件为所述移动终端根据下行参考信号的测量结果确定启动波束恢复机制或所述网络侧设备根据上行参考信号测量结果确定启动波束恢复机制。
本公开实施例提供的波束恢复处理方法主要应用在无线通信系统中，用于判断无线链路是否传输质量变差，并进行波束的恢复处理。
可以理解的是，上述网络侧设备(也可称为MF接入设备)可以是基站，当然可以理解的是，上述基站的形式不限，可以是宏基站(Macro Base Station)、微基站(Pico Base Station)、Node B(3G移动基站的称呼)、增强型基站(ENB)、家庭增强型基站(Femto eNB或Home eNode B或Home eNB或HNEB)、中继站、接入点、RRU(Remote Radio Unit，远端射频模块)、RRH(Remote Radio Head，射频拉远头)等。
具体的，本实施例中，可以根据上行参考信号或下行参考信号的测量结 果，确定无线链路是否传输质量变差，从而确定是否启动波束恢复机制。当无线链路传输质量变差时，确定启动波束恢复机制，当无线链路未变差时，确定无需启动波束恢复机制。
上述上行参考信号可以包括：上行业务信道的解调参考信号DMRS(De Modulation Reference Signal)和/或信道探测参考信号SRS(Sounding Reference Signal)等。
上述下行参考信号可以包括：下行业务信道的解调参考信号DMRS(De Modulation Reference Signal)和/或信道状态信息参考信号CSI-RS(Channel State Information-Reference Signal)等。
在本实施例中，网络侧设备可以直接对上行参考信号进行测量，从而监控波束质量，确定是否启动波束恢复机制。此外还可以由移动终端对下行参考信号进行测量，从而监控波束质量，并将监测的结果发送至网络侧设备，指示网络侧设备启动波束恢复机制。
无论是网络侧设备确定启动波束恢复机制，还是移动终端确定启动波束恢复机制，均会触发网络侧设备向移动终端发送第一指示消息，通过该第一指示消息指示新的BPL。应理解，指示新的BPL的数量可以根据实际需要进行设置，例如可以为一个BPL，也可以为多个PBL组成的PBL组。
步骤902，根据所述第一指示消息切换所述新的BPL进行数据传输。
该步骤中，网络侧设备在发送完第一指示消息后，将会切换BPL，与此同时移动终端在接收上述第一指示消息后，将会根据第一指示消息所指示的BPL切换BPL，从而在新的BPL上进行数据传输。
这样，本公开实施例中，移动终端接收网络侧设备所发送的第一指示消息，所述第一指示消息为网络侧设备满足预设触发条件时向所述移动终端发送的消息；所述第一指示消息用于指示新的波束对链接BPL；所述预设触发条件为所述移动终端根据下行参考信号的测量结果确定启动波束恢复机制或所述网络侧设备根据上行参考信号测量结果确定启动波束恢复机制；根据所述第一指示消息切换所述新的BPL进行数据传输。由于对上行参考信号或下行参考信号进行测量确定链路状态，并当链路传输质量变差需要启动波束恢复机制时，网络侧设备向移动终端发送第一指示信息，从而将移动终端和网 络侧设备切换至新的BPL上进行数据传输，相对于相关技术通过高层监测链路状态，并发起RRC重建，再进行波束训练，找到最优波束，恢复数据传输，本公开降低了波束恢复的时延。
在一些可选的实施例中，应当说明的是，对于链路状态的监测可以由移动终端进行，也可以由网络侧设备进行。以下移动终端进行链路状态的监测进行详细说明：
在一些可选的实施例中，参照图10，在上述步骤901之前，所述方法还包括：

在本实施例中，移动终端可以根据上述第二测量指标对下行参考信号进行测量，获得相应的结果，并根据测量的结果发送相应的目标数据，从而由网络侧设备根据该目标数据启动波束恢复机制。
步骤904，若所述下行参考信号的第二测量指标满足第二预设条件，根据第二测量指标的测量结果向网络侧设备发送目标数据，所述目标数据用于：网络侧设备确定是否满足预设触发条件。
该步骤中，上述第二预设条件的内容可以根据实际需要进行设置，例如本实施例中，当所述第二测量指标包括参考信号接收功率RSRP、小区参考信号功率相对小区所有信号功率的比值RSRQ、信噪比SNR和信道质量指示CQI中的至少一项时，所述第二预设条件包括：在预设时间段内所述第二测量指标低于对应的预设门限值的次数大于第二预设值；

上述目标数据上报的方式可以根据实际需要进行设置。此外上述目标数据的内容也可以根据实际需要进行设置，例如，可以是直接告知网络侧设备 启动波束恢复机制的消息，也可以是隐含告知网络侧设备是否启动波束恢复机制的消息。以下对此进行详细说明：
在一实施例中，移动终端可以通过物理随机接入信道PRACH的随机接入前导码preamble进行上报，即上述目标数据可以为物理随机接入信道PRACH的随机接入前导码preamble。为了与传统随机接入过程中的preamble相区别，可以设计为新的type，例如新的时频发送图样等。即根据某种规则向基站进行不同空间方向的轮流波束发射。
具体的，移动终端向基站发送PRACH preamble，可以是beam sweeping的方式如：以原BPL的方向为中心，与该方向由相近到远离的顺序依次发射上行波束；或者与该方向由远离到相近的顺序依次发射上行波束；或者与该方向的相近和远离方向的某个跳变顺序来依次发射上行波束。
在另一实施例中，移动终端可以向网络侧设备发送request，即上述目标数据可以为移动终端向网络侧设备发送的request消息。
在一些可选的实施例中，在所述request消息携带指示启动波束恢复机制的第一信令和/或指示启动波束恢复机制所使用的BPL的第二信令；或者，所述preamble携带所述第一信令和/或所述第二信令。例如，所述第一信令中通过1个数据位bit指示是否启动波束恢复。所述第二信令中通过预设数量的数据位bit指示所述移动终端监测获得的启动波束恢复机制所使用的BPL。
应当说明的是，启动波束恢复机制所使用的BPL可以是一个，也可以是多个(即BPL组)。本实施例中，指示所述移动终端监测获得的启动波束恢复机制所使用的BPL可以为移动终端检测到的最优的BPL，也可以是移动终端从最优的BPL中推荐的BPL，具体地，移动终端上报的BPL可以与网络侧设备当前使用的最优BPL保持不变，也可以更改为其他BPL，在此不做进一步的限定。
具体的，当采用request消息发送到网络侧设备，并由网络侧设备根据request消息确定是否启动波束恢复机制时，request消息的发送方式可以根据实际需要进行设置，例如上述request消息在上行控制信道上承载发送，或者使用宽波束发送，或者使用多个窄波束同时发送。

步骤905，接收所述网络侧设备发送的波束测量上报配置。
步骤906，根据所述波束测量上报配置向所述网络侧设备发送进行波束训练的结果，所述进行波束训练的结果用于：所述网络侧设备确定最优的BPL进行数据传输。
本实施例中，上述最优的BPL即为发射波束Tx beam和接收波束Rx beam的方向对齐，获得最优的数据传输质量。找到最优BPL可以是多个，BPL来自相同或者不同的TRP(Transmission and Reception Point发送接收点)。这里不限制多个TRP是否归属于同一个基站。TRP对于BPL的维护以及使用，可以通过基站来进行控制或交互。
也就是说，在本实施例中，所述最优的BPL包括一个或多个目标BPL。其中每一目标BPL的可以有一套或者两套BPL，即每一所述目标BPL包括针对控制信道传输的控制信道BPL和/或针对业务信道传输的业务信道BPL；其中所有的所述目标BPL包括至少一个所述控制信道BPL和至少一个所述业务信道BPL。
具体的，针对控制信道传输的控制信道BPL通常采用宽波束发送，也可以采用多个窄波束联合发送。业务信道BPL通常采用一个窄波束发送，对此还可以采用多个窄波束进行联合发送。也就是说在本实施例中，所述多个目标BPL进行数据传输的方式包括：相同的信息并且使用相同的时频资源、频分复用FDM、时分复用TDM和码分复用CDM的传输方式中的至少一项。
进一步的，对于指示的新的波束对链接BPL中的内容可以根据实际需要进行设置，例如，在一实施例中，所述指示新的波束对链接BPL包括：指示新的业务信道BPL。在另一实施例中，所述指示新的波束对链接BPL还包括：指示新的控制信道BPL。
此外，在指示新的业务信道BPL前，还可以对窄波束进行测量，确定最优的BPL，从而提高业务信道BPL传输的质量。参照图12所示，在上述步骤901之前，所述方法还包括以下步骤。
步骤907，接收网络侧设备发送的第二指示消息，所述第二指示消息用 于指示启动局部波束训练，所述局部波束训练为最优控制信道BPL内，进行窄波束训练；

如图6所示，两个TRP和移动终端之间分别建立了宽BPL(即控制信道BPL)和窄BPL(即业务信道BPL)。在宽BPL上可以发送相同的信息内容，从而在一个宽BPL被阻挡时，另一个BPL仍然可以正常使用。
如图7所示，业务信道的窄BPL被阻挡，但控制信道的宽BPL仍然能够连接，如图8所示，业务信道的窄BPL和控制信道的宽BPL均被阻挡。此时，移动终端上报request消息或者发送所述preamble时，除了携带指示启动波束恢复机制的第一信令(如1bit指示启动)，还可以携带最优的PDCCH(Physical Downlink Control Channel，物理下行控制信道)BPL和/或PDSCH BPL的第二信令。即，如果当前宽BPL质量仍然可以进行传输，可以继续使用。如果当前宽BPL虽然未中断但质量很差，或者当前宽BPL被阻挡了，那么此时request消息中要携带使用其他的新BPL的消息。
网络侧设备根据移动终端反馈的request消息，要向移动终端指示新的PDCCH波束和/或新的PDSCH波束。其中，新的PDCCH的波束可以是原来的宽BPL或者新的宽BPL；新的PDSCH波束可以是原来宽BPL中的其它窄BPL，或者新的宽BPL中的窄BPL。
此外，网络侧设备还可以向移动终端指示启动局部波束训练，例如在网络侧设备指示的宽BPL内，共包含3个窄波束，则对着3个窄波束进行轮流 发射，即局部波束训练。移动终端接收后反馈最优的窄波束，从而确定在宽BPL内的新的窄BPL。本实施例中，通过网络侧设备的指示，从而确定最终的新BPL，能够更加快速和准确。
