Description

辅服务小区波束失败的上报方法，装置和存储介质 技术领域
本公开涉及通信技术领域，尤其涉及一种辅服务小区波束失败的上报方法，装置和存储介质。
背景技术
在NR(New Radio，新的无线技术)中，特别是通信频段在frequency range2(6GHz以上)时，由于高频信道衰减较快，为了保证覆盖范围，需要使用基于波束的发送和接收。而在NR中，由于控制信道也需要使用基于波束的发送和接收，当用户设备发生移动，或者天线方向发生旋转时，当前配置给用户设备的用户用于接收PDCCH(Physical Downlink Control Channel，物理下行控制信道)的Rx beam(接收波束)可能会出现beam failure(波束失败)的问题。
目前的协议标准定义了用于检测beam failure的RS(Reference Signal，参考信号)资源，当用户设备检测到这些RS资源中所有RS上的信道质量都低于一个阈值threshold#1时，说明发生了beam failure。这时用户设备要根据基站配置的确定candidate beam(候选波束)的RS资源，检测该资源中的RS是否有L1-RSRP(L1-Reference Signal Received Power，层一的参考信号接收功率)满足阈值threshold#2的RS，若有，则用户设备在该RS对应的随机接入时频资源上发送该RS对应的随机接入前导码，隐性的告知基站该用户设备在该服务小区上发生了beam failure，并找到了新的波束(即该随机接入时频码资源对应的RS使用的波束)。随后，用户设备检测基站发送的响应消息，等待波束恢复。
但是，上述过程只是定义了用户设备的PCell(Primary cell，主服务小区)上的beam failure上报和恢复过程，而针对用户设备的SCell(Secondary Cell，辅服务小区)上的beam failure如何上报以及恢复，现有技术还未做考虑。

具体实施方式
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。
首先值得说明的是，本文中的符号“/”表示或者关系，例如“A/B”即为A或者B的含义，又例如，后文出现的“第一辅服务小区的PUCCH/PUSCH/PRACH是否可用”，应理解为“第一辅服务小区的PUCCH或者PUSCH或者PRACH是否可用”的含义，后文其他部分出现时，不再做具体说明。
进一步对本公开实施例的应用场景进行说明。本公开以下实施例可以应用于无线通信网络，例如：5G NR(New Radio)系统，LTE系统、LTE-A(Long Term Evolution Advanced，先进的长期演进)系统，及其进一步的演进网络。
无线通信网络中包括基站和用户设备。其中，基站可以是与用户设备或其它通信站点如中继站点进行通信的设备。基站可以提供特定物理区域的通信覆盖。例如，基站具体可以是5G NR系统的gNB，LTE系统中的演进型基站(EvolvedNode B，简称为ENB或eNodeB)；或者，也可以是无线通信网络中的提供接入服务的其他接入网设备。
在本公开实施例中，用户设备可以分布于整个无线通信网络中，每个用户设备可以是静态的或移动的。例如，该用户设备可以为蜂窝电话，个人数字助理(Personal Digital Assistant，PDA)，手持设备(Handheld)，膝上型电脑(Laptop Computer)等无线通信设备；该用户设备还可以是应用于机器间(Machine to Machine，M2M)通信的M2M终端，例如可以是智能电表、智能家电等支持M2M通信的设备。另外，值得说明的是，随着新一代AR(Augmented Reality，增强现实)和VR(Virtual Reality，虚拟现实)技术，以及车车通信等新型互联网应用的不断涌现，无线通信网络的部署场景越来越广，因此，用户设备类型也更加多种多样，本公开对此不做限定。
基于上述应用场景，下面对本公开实施例提供的一种辅服务小区波束失败的上报方法进行说明。
图1是本公开一示例性实施例示出的一种辅服务小区波束失败的上报方 法的流程图，该方法应用于用户设备，如图1所示，可以包括以下步骤：
在步骤S11中，确定用户设备的第一辅服务小区发生波束失败。
其中，该第一辅服务小区是该用户设备的任一辅服务小区。
在步骤S12中，确定用于向基站发送上报消息的目标服务小区。
其中，所述上报消息用于通知所述基站所述第一辅服务小区发生波束失败。
在具体实施时，在相应的条件下，该目标服务小区可以是该第一辅服务小区自身，也可以是用户设备的除第一辅服务小区以外的其他服务小区，后文将对用户设备各个服务小区能够作为所述目标服务小区的条件进行详细说明。
在步骤S13中，在所述目标服务小区上发送所述上报消息。
具体地，该用户设备可以接收所述基站发送的配置信令，并根据所述配置信令使用所述目标服务小区配置的PUCCH/PUSCH/PRACH发送所述上报消息的时频码资源。
另外，步骤S12确定的目标服务小区不同，上报消息通知基站第一辅服务小区发生波束失败的方式也可能不同，后文将具体说明。
采用上述方法步骤，当用户设备的任一辅服务小区发生波束失败时，可以确定用于发送通知基站该辅服务小区发生波束失败的上报消息的目标服务小区，其中，该目标服务小区具体可以是用户设备的除该辅服务小区以外的其他小区，在此种情况下，用户设备可以通过跨载波的方式在其他小区上发送上报该辅服务小区发生波束失败的消息，并且，在该辅服务小区自身的PUCCH/PUSCH/PRACH可用的情况下，还可以将该辅服务小区作为目标服务小区发送上报消息。从而确保了在用户设备的辅服务小区发生波束失败时，也能够正确的通知到基站。
下面对上述步骤进行详细说明，图2是本公开一示例性实施例示出的一种辅服务小区波束失败的上报方法的流程图，如图2所示，包括：
在步骤S11中，确定用户设备的第一辅服务小区发生波束失败。
在步骤S121中，在所述第一辅服务小区属于主小区基站控制的主小区组(MCG,Master Cell Group)的情况下，将所述用户设备的主服务小区作为用 于发送通知基站所述第一辅服务小区发生波束失败的上报消息的目标服务小区。
在步骤S13中，在所述目标服务小区上发送所述上报消息。
也就是说，图1中所示的步骤S12具体可以为步骤S121：在所述第一辅服务小区属于主小区基站控制的主小区组的情况下，将所述用户设备的主服务小区为用于发送通知基站所述第一辅服务小区发生波束失败的上报消息的目标服务小区。
图2只是本公开实施例一种可能的实现方式，在具体实施时，若所述第一辅服务小区属于辅服务基站控制的辅小区组(SCG，Secondary Cell Group)，则还可以将用户设备的主辅服务小区(PScell，Primary Secondary Cell)为用于发送通知基站所述第一辅服务小区发生波束失败的上报消息的目标服务小区。此外，用户设备的其他配置了PUCCH(Physical Uplink Control Channel，物理上行控制信道)/PUSCH(Physical Uplink Shared Channel，物理上行共享信道)/PRACH(Physical Random Access Channel，物理随机接入信道)的服务小区也可以作为发送所述上报消息的目标服务小区。
综上，步骤S13可以包括：将所述用户设备的主服务小区作为所述目标服务小区，其中，所述第一辅服务小区属于主小区基站控制的主小区组；或者，将所述用户设备的主辅服务小区作为所述目标服务小区，其中，所述第一辅服务小区属于辅服务基站控制的辅小区组；或者，将所述用户设备的除所述第一辅服务小区，所述主服务小区和所述主辅服务小区以外的其他配置了物理上行控制信道PUCCH/物理上行共享信道PUSCH/物理随机接入信道PRACH的服务小区作为所述目标服务小区。在具体实施时，可以对用户设备用于发送通知发生波束失败的上报消息的目标服务小区进行预先配置，这样，用户设备在确定任一辅服务小区发生波束失败后，直接可以根据配置确定目标服务小区。
下面对在以用户设备的第一辅服务小区以外的其他服务小区作为目标服务小区的情况下，上报消息具体如何发送进行详细说明：
方式一、将所述上报消息承载到所述目标服务小区的PUCCH/PUSCH上用于发送层一的参考信号接收功率L1-RSRP的序列值上，其中，所述上 报消息包括所述第一辅服务小区的小区标识以及用于指示发生波束失败的指示信息。
可选地，所述指示信息包括所述第一辅服务小区的一个或多个参考信号RS的标识和一个或多个参考信号RS的L1-RSRP，并且，当所述第一辅服务小区的用于检测波束失败的RS的L1-RSRP的比特值全部为预设比特值时，表明发生波束失败。也就是说，基站在接收到该上报消息后，可以通过该指示信息确定用户设备有服务小区发生波束失败，并通过该小区标识确定是该第一辅服务小区发生波束失败。
值得说明的是，现有技术中，L1-RSRP的上报是用7bit指示多个波束中L1-RSRP最强的波束的L1-RSRP绝对值，其他各个波束的L1-RSRP值使用与该最强L1-RSRP的相对值来指示，每个波束的相对值使用4bit来指示。而上述方式一是复用L1-RSRP的发送方法，使用发送L1-RSRP的比特的其中一个序列值来表示波束失败，例如，为了指示某个波束的波束失败，如果这个波束不是L1-RSRP最强的波束，则可以设定4bit其中一个序列值比如0000表示为该波束发生波束失败。如果这个波束是L1-RSRP最强的波束，则可以设定7bit其中一个序列值比如0000000表示为该波束发生波束失败。
方式二、将所述上报消息承载到所述目标服务小区的PUCCH/PUSCH上用于反馈信道质量指示CQI的序列值上，所述上报消息包括所述第一辅服务小区的小区标识以及所述第一辅服务小区的信道质量信息，当所述第一辅服务小区在信道质量低于预设阈值时，表明发生波束失败。
示例地，该信道质量信息可以包括第一辅服务小区的用于检测波束失败的RS上的CQI值，这样，本公开实施例可以设计为，在该第一辅服务小区的用于检测波束失败的RS上的CQI值全部低于预设阈值时，认为第一辅服务小区发生波束失败，该确定服务小区发生波束失败的条件具体可以在用户设备和基站之间事先约定。
方式三、将所述上报消息承载到所述目标服务小区的PUCCH/PUSCH上的调度请求SR的资源上，所述上报消息包括所述第一辅服务小区的小区标识以及用于指示发生波束失败的指示信息。
也就是说，可以复用SR资源，设计相应的指示信息，将指示信息与小 区标识作为上报消息发送给基站，通知是该第一辅服务小区发生波束失败。该指示信息可以参照方式一中复用L1-RSRP的方法，利用特定的比特值指示发生波束失败，此处不再赘述。
方式四、在所述目标服务小区的PUCCH/PUSCH上发送预定格式的上报消息，所述预定格式指定了PUCCH/PUSCH上承载所述上报消息的比特，以及用于表示所述第一辅服务小区的小区标识的比特值，以及表示用于指示发生波束失败的指示信息的比特值。
也就是说，方式一和方式三均复用了现有的发送资源，本公开实施例也可以设计专门用于指示波束失败的消息格式，在PUCCH/PUSCH上发送所述预定义格式的上报消息。
方式五、接收基站发送的预设PRACH时频码资源，所述预设PRACH时频资源用于发送所述第一辅服务小区发生波束失败的上报信息，并在所述预设PRACH时频资源上发送预设的随机接入前导码，以通知所述基站所述用户设备的所述第一辅服务小区发生波束失败。
也就是说，对于配置有PRACH的目标服务小区，则可以使用免竞争contention free的随机接入前导码(即上述预设的随机接入前导码)作为上报消息，在预设的PRACH时频资源上发送该随机接入前导码，该预设的PRACH时频资源是基站分配给用户设备专门发送通知第一辅服务小区发生波束失败的上报消息的资源，这样，基站只要在该预设的PRACH时频资源上接收到预设的随机接入前导码，则认为该第一辅服务小区发生波束失败。
在另一种可能的实现方式中，用户设备还可以使用第一辅服务小区的基于竞争contention based的随机接入前导码作为上报消息，在目标服务小区的PRACH时频资源上发送，以通知所述基站所述用户设备的所述第一辅服务小区发生波束失败。
可选地，除了将用户设备的除所述第一辅服务小区以外的其他服务小区作为目标服务小区，本公开实施例还可以在第一辅服务小区的PUCCH/PUSCH/PRACH可用的情况下，确定所述第一辅服务小区为所述目标服务小区，并在所述第一辅服务小区的PUCCH/PUSCH/PRACH资源上发送所述上报消息。示例地，图3是本公开一示例性实施例示出的一种辅服务 小区波束失败的上报方法的流程图，如图3所示，包括：
在步骤S11中，确定用户设备的第一辅服务小区发生波束失败。
在步骤S122中，确定所述第一辅服务小区的上的PUCCH/PUSCH/PRACH是否可用。
示例地，该用户设备可以通过以下两种方式确定第一辅服务小区的上的PUCCH/PUSCH/PRACH是否可用：
方式一、接收所述基站发送的指示消息，根据所述指示消息确定所述第一辅服务小区上的PUCCH/PUSCH/PRACH是否可用。
具体地，基站可以在确定用户设备在第一辅服务小区的下行接收失败时，判断是否能接收到用户设备在第一辅服务小区的PUCCH/PUSCH/PRACH上发送的上行信息，如果能接收到，则表明第一辅服务小区上的PUCCH/PUSCH/PRACH可用，在这种情况下，基站可以通过其他服务小区上的PDCCH或PDSCH来发送指示消息告知用户设备该第一辅服务小区上的PUCCH/PUSCH/PRACH还可用。因此，用户设备在接收到基站发送的该指示消息时，即可确定第一辅服务小区上的PUCCH/PUSCH/PRACH可用。
方式二、判断所述用户设备自身的接收和发送是否存在互易性，在所述用户设备自身的接收和发送不存在互易性时，确定所述第一辅服务小区上的PUCCH/PUSCH可用。
值得说明的是，互易性指的是，天线用作发信天线时的参数，与用作收信天线的参数保持不变。若用户设备自身的接收和发送存在互易性，则用户设备在下行失败时，上行大概率也会发生失败，若用户设备自身的接收和发送不存在互易性，则可认为用户设备在下行失败时，上行的PUCCH/PUSCH/PRACH仍然可用。
在步骤S123中，在所述第一辅服务小区上的PUCCH/PUSCH/PRACH可用时，将所述第一辅服务小区作为所述目标服务小区。
在步骤S131中，在所述第一辅服务小区的PUCCH/PUSCH/PRACH资源上发送所述上报消息。
也就是说，图1中所示的步骤S12可以包括：确定所述第一辅服务小区的上的PUCCH/PUSCH/PRACH是否可用；在所述第一辅服务小区上的 PUCCH/PUSCH/PRACH可用时，将所述第一辅服务小区作为所述目标服务小区。并且步骤S13包括：在所述第一辅服务小区的PUCCH/PUSCH/PRACH资源上发送所述上报消息。
下面对在以第一辅服务小区作为目标服务小区的情况下，上报消息具体如何发送进行详细说明：
方式一、在第一辅服务小区的PUCCH/PUSCH可用的情况下，将所述上报消息承载到所述第一辅服务小区的PUCCH/PUSCH上用于发送L1-RSRP的序列值上，其中，所述第一辅服务小区上的PUCCH/PUSCH可用。
具体地，所述上报消息可以包括所述第一辅服务小区的一个或多个参考信号RS的标识和一个或多个参考信号RS的L1-RSRP，当所述第一辅服务小区的用于检测波束失败的RS的L1-RSRP的比特值全部为预设比特值时，表明所述第一辅服务小区发生波束失败。
方式二、在第一辅服务小区的PUCCH/PUSCH可用的情况下，将所述上报消息承载到所述第一辅服务小区的PUCCH/PUSCH上用于反馈信道质量指示CQI的序列值上，其中，所述上报消息包括所述第一辅服务小区的信道质量信息，当所述第一辅服务小区的信道质量低于预设阈值时，表明所述第一辅服务小区发生波束失败，其中，所述第一辅服务小区上的PUCCH/PUSCH可用。
示例地，该信道质量信息可以包括第一辅服务小区的用于检测波束失败的RS上的CQI值，这样，本公开实施例可以设计为，在该第一辅服务小区的用于检测波束失败的RS上的CQI值全部低于预设阈值时，认为第一辅服务小区发生波束失败，该确定服务小区发生波束失败的条件具体可以在用户设备和基站之间事先约定。
图4是本公开一示例性实施例示出的一种辅服务小区波束失败的上报方法的流程图，如图4所示，包括：
在步骤S11中，确定用户设备的第一辅服务小区发生波束失败。
在步骤S124中，在所述第一辅服务小区上的PRACH可用时，将所述第一辅服务小区作为所述目标服务小区。
在步骤S132中，在所述第一辅服务小区上检测是否存在新的候选波束对应的参考信号RS。
在步骤S133中，若所述用户设备检测到新的候选波束对应的RS，则在所述新的候选波束的RS对应的所述第一辅服务小区的PRACH时频资源上发送对应的随机接入前导码，以通知所述基站所述用户设备的所述第一辅服务小区发生波束失败。
也就是说，在该用户设备的第一辅服务小区上的PRACH可用，且该用户设备检测到新的候选波束对应的参考信号RS的情况下，则用户设备可以在该RS对应的随机接入时频资源上发送该RS对应的随机接入前导码，隐性的告知基站该用户设备在该第一辅服务小区上发生了波束失败，并找到了新的波束(即该随机接入时频码资源对应的RS使用的波束)，以便基站可以利用该新的波束对该第一辅服务小区进行波束恢复。
图5是本公开一示例性实施例示出的一种辅服务小区波束失败的上报方法的流程图，如图5所示，包括：
在步骤S11中，确定用户设备的第一辅服务小区发生波束失败。
在步骤S122中，确定所述第一辅服务小区的上的PUCCH/PUSCH/PRACH是否可用。
