具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
图1示出了本申请一个示例性实施例提供的通信系统的框图，该通信系统可以包括：接入网12和终端设备14。
接入网12中包括若干个网络设备120。网络设备120可以是基站，所述基站是一种部署在接入网中用以为终端设备提供无线通信功能的装置。基站可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同，例如在LTE系统中，称为eNodeB或者eNB；在5G NR-U系统中，称为gNodeB或者gNB。随着通信技术的演进，“基站”这一描述可能会变化。为方便本申请实施例中的描述，上述为终端设备14提供无线通信功能的装置统称为网络设备。
终端设备14可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备，以及各种形式的用户设备，移动台(Mobile Station，MS)，终端(terminal device)等等。为方便描述，上面提到的设备统称为终端设备。网络设备120与终端设备14之间通 过某种空口技术互相通信，例如Uu接口。
本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile Communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)系统、先进的长期演进(Advanced long Term Evolution，LTE-A)系统、新无线(New Radio，NR)系统、NR系统的演进系统、非授权频段上的LTE(LTE-based access to Unlicensed spectrum，LTE-U)系统、NR-U系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统、无线局域网(Wireless Local Area Networks，WLAN)、无线保真(Wireless Fidelity，WiFi)、下一代通信系统或其他通信系统等。
通常来说，传统的通信系统支持的连接数有限，也易于实现，然而，随着通信技术的发展，移动通信系统将不仅支持传统的通信，还将支持例如，设备到设备(Device to Device，D2D)通信，机器到机器(Machine to Machine，M2M)通信，机器类型通信(Machine Type Communication，MTC)，车辆间(Vehicle to Vehicle，V2V)通信以及车联网(Vehicle to Everything，V2X)系统等。本申请实施例也可以应用于这些通信系统。
在5G NR系统中，上述网络设备120可以替换实现为N个传输接收点(Transmission Reception Point，TRP)。
图2示出了本申请一个示例性实施例提供的基于多个TRP或多个天线面板(multi-TRP/panel)的数据传输的示意图。
终端设备210处于服务小区(serving cell)之中，也处于邻小区(neighboring cell)之中。
其中，每个小区可以由不止一个TRP来覆盖。如图所示，serving cell由TRP1和TRP2联合覆盖，从而增大了serving cell的覆盖半径。neighboring cell由TRP3覆盖。
每个TRP可以设置有一个以上的天线面板(panel)。不同的天线面板的朝 向可以不同，从而可以收发不同传输方向的波束，从而实现多空间分集。网络设备可以使用多个panel(该多个panel可以来自同一个TRP或不同的TRP)同时向终端设备210发送PDCCH。这种情况下，不同panel的发送方向不一样，所以终端设备210也需要使用不同的panel来接收PDCCH，那么网络设备需要指示不同的传输配置指示(Transmission Configuration Indication，TCI)状态给终端设备，每个TCI状态对应终端设备的每个panel上的一个接收波束方向。通过上述基于波束(beam)的发送和接收方式，可以保证覆盖范围。
当终端设备210移动到小区边缘时，可能panel#1上测得服务小区的性能好，而panel#2测得邻小区的性能好，则终端设备210继续留在服务小区或者切换到邻小区，吞吐量都达不到最优，因为终端可能在两个cell覆盖范围的重叠位置，则最优的办法为不同cell同时基于波束与终端设备210进行数据传输，且波束动态切换。而由于不同cell之间通信会带来延时，所以inter-cell multi-TRP为终端设备210服务时，使用多下行控制信息(Downlink Control Information，DCI)信令的方式，也即multi-DCI方式，各个cell各自发送DCI调度(Physical Downlink Shared Channel，PDSCH)物理下行共享信道或(Physical Uplink Shared Channel，PUSCH)物理上行共享信道等信道传输，也就是说，邻小区也需要发送DCI信令给终端，DCI信令是通过(Physical Downlink Control Channel，PDCCH)物理下行控制信道发送的。
具体地，网络设备可以通过信令指示TCI状态，从而告知终端设备210接收时需要使用的接收波束。其中，每个TCI状态对应一个参考信号(Reference Signal，RS)标识，该RS既可以是非零功率信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)，也可以是同步信号块(Synchronization Signal Block，SSB)或探测参考信号(Sounding Reference Signal，SRS)。
图3示出了本申请一个示例性实施例提供的波束失败的检测方法的流程图，以该方法应用于如图1所示的终端设备中为例进行说明，如图3所示，该方法包括：
步骤301，确定用于第一邻小区波束失败beam failure检测的目标参考信号资源。
目标参考信道资源可以是基站向终端设备专门配置的用于检测第一邻小区 beam failure的参考信号资源，也可以是默认参考信号资源。
其中，针对基站配置参考信号资源和默认参考信号资源分别进行说明：
第一，目标参考信号资源的时频资源位置为基站向终端设备配置的，终端设备接收配置指令，该配置指令中包括目标信息字段，目标信息字段用于指示接收目标参考信号资源的时频资源位置，其中，目标参考信号资源包括一个或多个参考信号资源内，终端设备根据该配置指令在配置指令指示的时频资源位置上检测目标参考信号资源。
在一种可能的实施方式中，配置指令为终端设备所在的服务小区的基站向终端设备发送的指令，且该配置指令可以是无线资源控制(Radio Resource Control，RRC)信令，即服务小区的基站通过RRC信令配置用于检测第一邻小区beam failure的RS资源。在一些实施例中，在进行RS资源配置过程中，基站还需要告知终端设备接收RS资源所需的信息，如：第一邻小区ID，该ID可以是物理小区标识Physical Cell ID；或该ID为第一邻小区在为该终端提供服务的多个服务小区和/或邻小区中的小区编号，RS ID，RS类型，以及该RS对应的时频资源位置中的一项或多项信息。
第二，目标参考信号资源包括默认参考信号资源。在一些实施例中，当服务小区的基站未向终端设备配置用于对第一邻小区进行beam failure检测的RS资源时，终端设备使用默认的RS资源。在一些实施例中，默认RS资源包括终端接收该第一邻小区发送的控制资源集合(Control Resource Set，CORESET)时使用的TCI状态对应的RS资源。在一种可能的实施方式中，每个CORESET对应一个TCI状态，每个TCI状态对应一个RS资源。
在一种可能的实施方式中，终端设备通过TCI状态来确定接收波束时，基站通过RRC信令通知终端设备至少一个TCI状态，包括TCI状态的标识及其对应的RS类型和RS标识，终端设备接收PDCCH时使用的接收波束与接收该TCI状态对应的RS时接收功率最强时所使用的接收波束相同。也即，TCI状态用于指示终端设备接收PDCCH或PDSCH时，使用与接收基站发送的目标RS一样的接收beam；或指示终端设备发送PUCCH或PUSCH时，使用与发送目标RS一样的发送beam。
在一些实施例中，当终端设备被配置的需要接收的第一邻小区的CORESET中包括n个CORESET时，终端设备确定第一邻小区的n个CORESET中的m个CORESET，并确定m个CORESET的TCI状态对应的RS资源为默认参考信 号资源，其中，m、n为正整数，且m＜n。
在一些实施例中，终端设备从n个CORESET中，选择CORESET ID最小的m个CORESET的TCI状态对应的RS资源用于进行beam failure检测。
步骤302，根据目标参考信号资源对第一邻小区进行beam failure检测。
响应于目标参考信号资源的信道质量低于第一门限，确定第一邻小区发生beam failure。
在一些实施例中，当UE检测到第一邻小区所有需要被检测的目标RS资源的信道质量都低于第一门限时，则确定第一邻小区发生了beam failure。
在一些实施例中，信道质量包括层1参考信号接收功率(L1Reference Signal Receiving Power，L1-RSRP)，和/或，信道质量包括层1信号干扰噪声比(L1Signal-to-Interference and Noise Ratio，L1-SINR)。
在一些实施例中，当UE检测到第一邻小区发生beam failure时，根据基站的配置检测第一邻小区的候选波束对应的候选RS资源，响应于候选波束对应的候选RS资源中，第一候选RS资源的参考信号接收功率(Reference Signal Receiving Power，RSRP)达到第二门限，则将第一候选RS资源对应的候选波束方向作为第一邻小区的新波束方向。
综上所述，本申请实施例提供的波束失败的检测方法，通过配置的目标参考信号资源，或者默认的参考信号资源实现终端对邻小区的波束失败检测，提供了邻小区的波束失败检测方法。
图4是本申请另一个示例性实施例提供的波束失败的检测方法的流程图，以该方法应用于如图1所示的终端设备和网络设备中为例进行说明，如图4所示，该方法包括：
步骤401，网络设备向终端设备发送配置信令，配置信令中包括目标信息字段，目标信息字段用于指示接收目标参考信号资源的时频资源位置。
在一些实施例中，目标RS资源用于终端对第一邻小区进行波束失败检测。
在一些实施例中，该网络设备可以是终端设备所在服务小区的基站，由该基站向终端设备进行目标RS资源的配置。
在一些实施例中，该配置指令可以是RRC信令，即服务小区的基站通过RRC信令配置用于检测第一邻小区beam failure的RS资源。在一些实施例中，在进行RS资源配置过程中，基站还需要告知终端接收RS资源所需的信息，如： 第一邻小区ID，RS ID，RS类型，以及该RS对应的时频资源位置中的一项或多项信息。
步骤402，终端设备接收配置信令。
在一些实施例中，目标参考信号资源包括一个或多个参考信号资源。
步骤403，终端设备确定用于第一邻小区beam failure检测的目标参考信号资源。
终端设备根据配置信令中指示的时频资源位置接收目标RS资源。
步骤404，终端设备根据目标参考信号资源对第一邻小区进行beam failure检测。
响应于目标参考信号资源的信道质量低于第一门限，确定第一邻小区发生beam failure。
在一些实施例中，当UE检测到第一邻小区所有需要被检测的目标RS资源的信道质量都低于第一门限时，则确定第一邻小区发生了beam failure。
在一些实施例中，当UE检测到第一邻小区发生beam failure时，根据基站的配置检测第一邻小区的候选波束对应的候选RS资源，响应于候选波束对应的候选RS资源中，第一候选RS资源的RSRP达到第二门限，则将第一候选RS资源对应的候选波束方向作为第一邻小区的新波束方向。
综上所述，本申请实施例提供的波束失败的检测方法，通过配置的目标参考信号资源，或者默认的参考信号资源实现对邻小区的波束失败检测，提供了邻小区的波束失败检测方法。
在一个可选的实施例中，UE在检测到第一邻小区beam failure时，还需要将beam failure信息上报至网络设备，图5是本申请一个示例性实施例提供的波束失败的上报方法流程图，以该方法应用于终端设备中为例进行说明，如图5所示，该方法包括：
步骤501，确定用于第一邻小区波束失败beam failure检测的目标参考信号资源。
目标参考信道资源可以是基站向终端设备专门配置的用于第一邻小区beam failure检测的参考信号资源，也可以是默认参考信号资源。
其中，针对基站配置参考信号资源和默认参考信号资源分别进行说明：
第一，目标参考信号资源的时频资源位置为基站向终端设备配置的，终端 设备接收配置指令，该配置指令中包括目标信息字段，目标信息字段用于指示接收目标参考信号资源的时频资源位置；
第二，目标参考信号资源包括默认参考信号资源。
步骤502，响应于目标参考信号资源的信道质量低于第一门限，确定第一邻小区发生beam failure。
在一些实施例中，当UE检测到第一邻小区所有需要被检测的目标RS资源的信道质量都低于第一门限时，则确定第一邻小区发生了beam failure。
步骤503，向服务小区上报第一邻小区的beam failure信息。
服务小区包括主小区(Primary Cell，PCell)或主辅小区(Primary Secondary Cell，PScell)或配置有PUCCH的辅小区(Secondary Cell，SCell)。
步骤504，向第二邻小区上报beam failure信息。
第二邻小区为主邻小区或主辅邻小区，比如有多个邻小区为终端提供服务，而其中有一个邻小区设置为终端的主邻小区或主辅邻小区。
值得注意的是，上述步骤503和步骤504，可以仅执行步骤503，也可以仅执行步骤504，还可以同时执行步骤503和步骤504。
在一些实施例中，beam failure信息的上报可以是在检测到第一邻小区发生beam failure后执行的，也可以是在检测到第一邻小区发生beam failure，并检测到第一邻小区的新波束方向后执行的。当beam failure信息的上报在检测到第一邻小区发生beam failure后直接执行时，该beam failure信息用于指示第一邻小区发生beam failure；当beam failure信息的上报在检测到第一邻小区的新波束方向后执行时，beam failure信息用于指示第一邻小区发生beam failure，以及第一邻小区的新beam方向。
在一些实施例中，在对beam failure信息进行上报时，可以通过PUCCH进行上报，也可以通过PUSCH进行上报。
对PUCCH上报beam failure信息和PUSCH上报beam failure信息分别进行说明：
第一、通过PUCCH上报beam failure信息
在一些实施例中，通过PUCCH上报beam failure信息时，beam failure信息用于指示存在第一邻小区发生beam failure，其中，上报第一邻小区beam failure的方式与上报服务小区beam failure的方式可以是相同的也可以是不同的。
其中，当上报第一邻小区beam failure的方式与上报服务小区beam failure 的方式相同时，在服务小区的beam failure的上报过程中，使用PUCCH中用于波束失败恢复(Beam Failure Recovery，BFR)的调度请求(Scheduling Request，SR)进行上报，则上报第一邻小区发生beam failure时使用的调度请求，与上报服务小区发生beam failure时使用的调度请求，时频域资源和码字指示方法相同，即，上报第一邻小区发生beam failure与上报服务小区发生beam failure共用同一个SR。
当上报第一邻小区beam failure的方式与上报服务小区beam failure的方式不同时，不同点包括如下情况中的至少一种：
1)上报第一邻小区发生beam failure时使用的调度请求，与上报服务小区发生beam failure时使用的调度请求，时频域资源不同；
即，上报第一邻小区发生beam failure时使用的SR的时域资源与上报服务小区发生beam failure时SR的时域资源不同；和/或，上报第一邻小区发送beam failure时使用的SR的频域资源与上报服务小区发生beam failure时SR的频域资源不同。
2)上报第一邻小区发生beam failure时使用的SR与上报服务小区发送beam failure时使用的SR码字指示方法不同。
在一些实施例中，调度请求中包括指示字段，当该指示字段取第一取值，则该指示字段用于指示邻小区发生beam failure；当指示字段取第二取值时，则表示服务小区发生beam failure。也即，在SR码字的原有基础上增加一个指示字段，用于区分SR的指示对象为服务小区还是邻小区。
以该指示字段为1bit为例，如：当指示字段取值为1时，则表示SR针对邻小区发生beam failure进行指示，当指示字段取值为0时，则表示SR针对服务小区发生beam failure进行指示。
在一些实施例中，当服务小区和第一邻小区用于BFR的SR存在资源碰撞，且仅1bit字段可用于指示beam failure时，优先发送服务小区的SR。
以该指示字段为2bit为例，如：当指示字段取值为00，则表示存在上行数据需要发送，01则表示服务小区发生beam failure，10则表示邻小区发生beam failure，11则表示同时存在上行数据需要发送，且服务小区和/或邻小区发生beam failure。
第二、通过PUSCH上报beam failure信息
在一些实施例中，通过PUSCH上报beam failure信息时，beam failure信息 用于指示第一邻小区的小区编号，也即，通过PUSCH上报发生beam failure的第一邻小区的小区编号。在一些实施例中，通过PUSCH发送指示信令，该指示信令中包括发生beam failure的第一邻小区的小区编号。在一些实施例中，通过PUSCH上的媒体介入控制控制单元MAC CE信令发送发生beam failure的第一邻小区的小区编号。
在一些实施例中，服务小区与邻小区联合编号；或，服务小区与邻小区独立编号。
当服务小区与邻小区联合编号时，从服务小区与邻小区的联合编号中确定第一邻小区的小区编号；或，当服务小区与邻小区独立编号时，从邻小区的独立编号中确定第一邻小区的小区编号。
示意性的，当服务小区与邻小区联合编号，则邻小区也使用SCell编号依次取值1，2，3，…；当服务小区与邻小区独立编号，则邻小区的编号为邻小区(Neighboring Cell，NCell)编号，依次取值0，1，2，3，…。
在一些实施例中，通过PUSCH上报beam failure信息时，可以在确定第一邻小区发生beam failure后，通过PUSCH上报第一邻小区的小区编号，也即，上述指示信令中包括第一邻小区的小区编号；也可以确定第一邻小区发生beam failure，且确定第一邻小区的新波束方向后，通过PUSCH上报第一邻小区的小区编号，以及指示第一邻小区的新波束方向；还可以确定第一邻小区发生beam failure时，通过PUSCH上报第一邻小区的小区编号，并指示第一邻小区无新波束方向。
终端在检测到第一邻小区发生beam failure时，检测第一邻小区的候选波束对应的候选RS资源，并响应于第一候选RS资源对应的参考信号接收功率RSRP达到第二门限时，通过PUSCH上报新波束方向指示信息，新波束方向指示信息包括第一候选参考信号资源对应的参考信号资源编号；或，通过PUSCH上报新波束方向指示信息，新波束方向指示信息用于指示无新波束方向，在一些实施例中，当检测第一邻小区的候选波束对应的候选RS资源时，未检测到RSRP达到第二门限的候选RS资源时，通过新波束方向指示信息指示第一邻小区无新波束方向。
步骤505，向第一邻小区上报beam failure信息。
在一些实施例中，向第一邻小区上报beam failure信息时，可以通过物理随机接入信道(Physical Random Access Channel，PRACH)向第一邻小区上报beam  failure信息，该beam failure信息用于指示第一邻小区发生beam failure。在一些实施例中，终端在检测到第一邻小区发生beam failure之后，检测第一邻小区的候选波束对应的候选RS资源，当存在第二候选RS资源对应的参考信号接收功率RSRP达到第二门限时，终端根据该RS资源对应的PRACH时频码资源，在相应的PRACH时频资源上发送相应的随机接入前导码，即发送beam failure信息指示告知第一邻小区发生beam failure。
在一些实施例中，上述第二候选RS资源与第一候选RS资源可以是同一个候选RS资源，也可以是不同的候选RS资源，本申请实施例对此不加以限定。
在一些实施例中，向第一邻小区上报beam failure信息时，当终端设备与网络设备之间的上下行信道不对称时，也可以通过PUCCH或PUSCH上报；当终端设备与网络设置之间的上下行信道对称时，则通过PUCCH或PUSCH上报beam failure信息会由于beam failure而发送失败。
综上所述，本申请实施例提供的波束失败的检测方法，通过配置的目标参考信号资源，或者默认的参考信号资源实现对邻小区的波束失败检测，提供了邻小区的波束失败检测方法。
本实施例提供的方法，通过PUCCH或PUSCH上报beam failure信息，从而服务小区的网络设备或者邻小区的网络设备能够接收到邻小区的beam failure信息，对邻小区发生的beam failure进行获知，并从而实现beam failure的恢复。
图6是本申请一个示例性实施例提供的波束失败的检测方法的流程图，以该方法应用于如图1所示的终端设备和网络设备中为例，如图6所示，该方法包括：
步骤601，终端设备确定用于第一邻小区beam failure检测的目标参考信号资源。
目标参考信道资源可以是基站向终端设备专门配置的用于第一邻小区beam failure检测的参考信号资源，也可以是默认参考信号资源。
步骤602，响应于目标参考信号资源的信道质量低于第一门限，终端设备确定第一邻小区发生beam failure。
在一些实施例中，当UE检测到第一邻小区所有需要被检测的目标RS资源的信道质量都低于第一门限时，则确定第一邻小区发生了beam failure。
步骤603，终端设备上报第一邻小区的beam failure信息。
在一些实施例中，终端设备可以向服务小区的网络设备上报第一邻小区的beam failure信息，也可以向邻小区的网络设备上报第一邻小区的beam failure信息，还可以既向服务小区的网络设备上报第一邻小区的beam failure信息，又向邻小区的网络设备上报第一邻小区的beam failure信息。其中，终端设备可以向第一邻小区本身上报beam failure信息，也可以向第二邻小区上报beam failure信息。
步骤604，网络设备接收终端上报的beam failure信息。
在一些实施例中，该网络设备可以是终端设备的服务小区对应的网络设备，也可以是终端设备的邻小区对应的网络设备。
在一些实施例中，在接收beam failure信息时，当网络设备为服务小区的网络设备，或第二邻小区的网络设备时，可以通过PUCCH接收beam failure信息，也可以通过PUSCH接收beam failure信息。
对通过PUCCH接收beam failure信息和通过PUSCH接收beam failure信息分别进行说明：
第一、通过PUCCH接收beam failure信息
使用PUCCH中用于BFR的SR进行上报。其中，上报第一邻小区发生beam failure时使用的调度请求，与上报服务小区发生beam failure时使用的调度请求，时频域资源和码字指示方法相同；或，上报第一邻小区发生beam failure时使用的调度请求，与上报服务小区发生beam failure时使用的调度请求时频域资源不同；或，上报第一邻小区发生beam failure时使用的调度请求，与上报服务小区发生beam failure时使用的调度请求码字指示方法不同。
第二、通过PUSCH接收beam failure信息
在一些实施例中，从PUSCH接收指示信令，指示信令中包括发生beam failure的第一邻小区的小区编号。
在一些实施例中，服务小区与邻小区联合编号；或，服务小区与邻小区独立编号。
当服务小区与邻小区联合编号时，从联合编号中确定指示信令中指示的小区编号对应的第一邻小区；或，当服务小区与邻小区独立编号时，从邻小区的独立编号中确定指示信令中指示的小区编号对应的第一邻小区。
在一些实施例中，指示信令中还包括新波束方向指示信息。其中，该新波束方向指示信息包括第一候选参考信号资源的参考信号资源编号，第一候选参 考信号资源为参考信号接收功率达到第二门限的候选信号资源；或，新波束方向指示信息用于指示第一邻小区无新波束方向，也即，未检测到候选参考信号资源的参考信号接收功率达到第二门限。
在一些实施例中，当网络设备为第一邻小区的网络设备时，可以通过PRACH接收beam failure信息，该beam failure信息用于指示第一邻小区本身与终端设备之间发生beam failure。
综上所述，本申请实施例提供的波束失败的检测方法，通过配置的目标参考信号资源，或者默认的参考信号资源实现对邻小区的波束失败检测，提供了邻小区的波束失败检测方法。
本实施例提供的方法，通过PUCCH或PUSCH上报beam failure信息，从而服务小区的网络设备或者邻小区的网络设备能够接收到邻小区的beam failure信息，对邻小区发生的beam failure进行获知，并从而实现beam failure的恢复。
