Description

波束失败确定方法、装置、设备及存储介质 技术领域
本申请涉及移动通信领域，特别涉及一种波束失败确定方法、装置、终端及介质。
背景技术
在新空口(New Radio，NR)系统中，特别是通信频段在频段范围2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(beam)的发送和接收。
而在NR系统中，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(User Equipment，UE)发生移动，或者天线方向发生旋转时，当前配置给UE的用于发送接收物理下行控制信道(Physical Downlink Control Channel，PDCCH)的接收波束或发送波束可能会出现问题，即出现了波束失败的问题。目前的通信协议定义了用于检测波束失败的参考信号资源集合q0，当UE检测到这些参考信号资源集合中所有参考信号上的无线链路质量都低于一个门限值#1时，说明发生了波束失败。这时，UE要根据基站配置的确定候选波束的参考信号资源集合q1，检测参考信号资源集合中的各个参考信号中是否有参考信号接收功率(Reference Signal Received Power，RSRP)满足门限值#2的参考信号。若有，则UE在告知基站发生波束失败时，也可以告知新的候选波束，供基站为终端配置新的波束。

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。
在本公开以下的所有实施例中，虽然不同的步骤采用了数字来进行编号，但是这些编号都只是为了使得文字更为清楚的目的而进行的编号，并非是对于步骤的执行顺序和时隙的限定。本公开的所有实施例中，这些编号的步骤可以被单独实施，也可以被任何组合在一起实施；当这些步骤被任意组合在一起实施时，其执行顺序并不受到编号的数字的限制，即其可以以任意的顺序被执行。
首先对本申请涉及的若干个技术术语进行简介：
随机接入过程
随机接入过程是指从终端设备发送前导码开始尝试接入网络到与网络间建立起基本的信令连接之前的过程，随机接入过程是对于任意一个蜂窝通信系统的最基本要求之一，用于使终端设备与网络侧建立数据通信。
随机接入过程分为：四步(4-step)随机接入和两步(2-step)随机接入。
四步随机接入
图1示出了在基于竞争的随机接入过程中，随机接入过程的4个步骤包括：
(1)终端设备设备向网络设备发送消息1：前导码(preamble)。
终端设备向网络设备发送前导码(preamble)，网络设备据此估计终端设备的传输时延以实现上行同步。
(2)网络设备向终端设备发送消息2：随机接入响应(Random Access Response,RAR)。
网络设备基于上述步骤(1)中估计得到的传输时延，发送时间提前(timing advance)命令，以调整终端设备的发送时间。消息2由网络设备的媒体接入控制层(Media Access Control，MAC)组织，并由下行共享信道(Down Link Share Channel，DL_SCH)承载。
网络设备采用物理下行控制信道(Physical Downlink Control Channel，PDCCH)调度消息2，并通过C-RNTI或RA-RNTI进行寻址(也称加扰)，RA-RNTI由承载消息1的物理随机接入信道(Physical Random Access Channel，PRACH) 时频资源位置确定。消息2包含上行传输定时提前量，为消息3分配上行资源和临时C-RNTI。
(3)终端设备向网络设备发送消息3：第一次调度传输。
终端设备在收到消息2后，在分配的上行资源上传输消息3，通过物理上行共享信道(Physical Uplink Share Channel，PUSCH)向网络设备发送用户设备身份(User Equipment Identify，UE ID)。
(4)网络设备向终端设备发送消息4：竞争解决消息。
网络设备在物理下行共享信道(Physical Downlink Share Channel，PDSCH)上发送给终端设备的竞争解决消息。
两步随机接入
在基于竞争的随机接入的过程中，可以将4步的随机接入过程合并成2步的随机接入过程，结合图2，合并后包括消息A和消息B，相关步骤包括：
(1)终端设备向网络设备发送消息A。
(2)网络设备接收到终端设备发送的消息A后，向终端设备发送消息B。
可选地，消息A包括消息1和消息3的内容，也即消息A包括：前导码和UE ID，UE ID可以是：小区无线网络临时标识符(Cell Radio Network Temporary Identifier，C-RNTI)、临时C-RNTI、随机接入无线网络临时标识符(Random Access Radio Network Temporary Identifier，RA-RNTI)、非接入层(Non-Access Stratum)UE ID中的一种。
可选地，消息B包括消息2和消息4的内容，也即消息B包括：随机接入响应和竞争解决消息。
图3示出了本公开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。为方便本公开实施例中的描述，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。在车联网通信中，网络设备还可以是车载终端设备。
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、计算设备或物联网(Internet of Things，IoT)设备或工业物联网(Industry Internet of Things，IIoT)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。
本公开实施例的技术方案可以应用于各种通信系统，例如：频分双工(Frequency Division Duplex，FDD)系统、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。本公开实施例也可以应用于这些通信系统。
对于终端的每个服务小区包括：主小区(Primary Cell，Pcell)，主辅小区(Primary Secondary Cell，PScell)，辅小区(Secondary Cell，SCell)的每个带宽部分(Bandwidth Part，BWP)上，最多只配置1个q0和1个q1，q0是用于波束失败检测的参考信号资源集合，q1是用于候选波束发现的参考信号资源集合。即使是对于一个服务小区的激活BWP上，终端被配置了多个TRP来发送PDCCH的情况，也是只针对服务小区来配置1个q0和1个q1。那么就存在一个技术问题：由于q0和q1都是针对服务小区来配置的，不区分服务小区的多个TRP。但实际上，当终端被配置为要监测该服务小区的多个TRP的PDCCH时，可能TRP1的PDCCH发生波束失败，而TRP2的波束链路正常，由于基站不知道UE侧的波束情况，就会继续使用TRP1和TRP2为终端发送PDCCH。若TRP1和TRP2发送的PDCCH指示内容一样，即TRP1是为了重复发送TRP2的PDCCH，那么TRP1发生了波束失败就会影响PDCCH的可靠性。如果TRP1发送的PDCCH只是为了调度TRP1的PDSCH或PUSCH，那么TRP1发生了波束失败就会影响PDCCH资源和PDSCH/PUSCH资源的浪费，以及增大终端监测没必要的PDCCH的功耗。
图4示出了本申请一个实施例提供的波束失败确定方法的流程图。该方法应用于如图1所示的终端中来举例说明。该方法包括：
步骤402：确定用于波束失败检测的N个参考信号资源集合，以及每个参考信号资源集合对应的TRP标识；
N个参考信号资源集合中存在不同的至少两个参考信号资源集合，至少两个参考信号资源集合对应的TRP标识不同，且至少两个参考信号资源集合对应的物理小区标识相同。
示意性的，存在参考信号资源集合1对应TPR1，参考信号资源集合2对应TRP2。其中，TRP1和TRP2是不同的两个TRP，且TRP1和TRP2均对应同一个服务小区1。
N个参考信号资源集合与N个TRP标识的对应关系，可以为如下四种方式中的任意一种：
·TRP标识包括控制资源集索引标识(CORESET pool index)，控制资源集索引标识与TRP一一对应；
·TRP标识包括参考信号资源集合索引，参考信号资源集合索引与TRP一一对应；
·TRP标识包括参考信号资源索引，参考信号资源索引与TRP一一对应；
·TRP标识包括TRP编号。
示意性的，物理小区标识包括：终端的服务小区和/或邻小区的物理小区标识。
示意性，参考信号资源包含：同步信号块(Synchronization Signal Block，SSB)、信道状态信息参考信号(Channel-Slate Information Reference Signal，CSI-RS)、定位参考信号(Positioning Reference Signal，PRS)、追踪参考信号(Tracking Reference Signal，TRS)、探测参考信号(Sounding Reference Signal，SRS)中的至少一种。
综上所述，本实施例提供的方法，通过为终端设置至少两个参考信号资源集合，至少两个参考信号资源集合对应的TRP标识不同，且物理小区标识相同，能够在同一个服务小区的多个TRP中的某一个TRP发生波束失败时，终端也能准确判断出该TRP的波束失败事件，进而向基站准确上报波束失败确定，避免通信资源的浪费。
在基于图4的一个可选实施例中，上述步骤402可采用如下三种方式中的至少一种来实现：
1、网络设备向终端发送第一配置信息，第一配置信息用于配置N个参考信号资源集合，以及N个参考信号资源集合对应的TRP标识。终端接收来自网络设备的第一配置信息，根据第一配置信息确定用于波束失败检测的N个参考信号资源集合。表一示意性的给出了N个参考信号资源集合。
表一
集合 TRP
参考信号资源集合1 TRP ID 1
参考信号资源集合2 TRP ID 2
2、终端确定默认的N个参考信号资源集合，以及N个参考信号资源集合对应的TRP标识。
对于该N个TRP中的每个TRP，默认的参考信号资源集合是目标TCI状态对应的参考信号资源集合，目标TCI状态是为终端配置的监测该TRP对应的CORESET上的PDCCH时的传输配置指示(Transmission Configuration Indication，TCI)状态。
比如，对于TRP1，与TRP1对应的默认的参考信号资源集合包含TCI状态1对应的参考信号资源，TCI状态1是为终端配置的监测TRP1对应的CORESET上的PDCCH时的TCI状态。又比如，对于TRP2，与TRP2对应的默认的参考 信号资源集合包含TCI状态2对应的参考信号资源，TCI状态2是为终端配置的监测TRP2对应的CORESET上的PDCCH时的TCI状态。表二示意性的给出了N个参考信号资源集合。
表二
集合 TCI状态 TRP
参考信号资源集合0 TCI状态0 TRP ID 1
参考信号资源集合1 TCI状态1 TRP ID 2
参考信号资源集合5 TCI状态5 TRP ID 3
可以理解的是，表二中的每一个元素都是独立存在的，这些元素被示例性的列在同一张表格中，但是并不代表表格中的所有元素必须根据表格中所示的同时存在。其中每一个元素的值，是不依赖于表二中任何其他元素值。因此本领域内技术人员可以理解，该表二中的每一个元素的取值都是一个独立的实施例。
3、网络设备向终端发送第二配置信息，第二配置信息用于配置N个参考信号资源集合中的第一部分参考信号资源集合，以及第一部分参考信号资源集合对应的TRP标识。终端接收来自网络设备的第二配置信息，根据第二配置信息确定第一部分参考信号资源集合。此外，终端还确定默认的第二部分参考信号资源集合，第二部分参考信号资源集合是N个参考信号资源集合中除第一部分参考信号资源集合之外的剩余集合。
图5示出了本申请一个实施例提供的波束失败确定方法的流程图。该方法应用于如图1所示的终端中来举例说明。该方法包括：
步骤502：终端确定用于波束失败检测的N个参考信号资源集合，以及每个参考信号资源集合对应的TRP标识。
N个参考信号资源集合中存在不同的至少两个参考信号资源集合，至少两个参考信号资源集合对应的TRP标识不同，且至少两个参考信号资源集合对应的物理小区标识相同。
示意性的，存在参考信号资源集合1对应TPR1，参考信号资源集合2对应TRP2。其中，TRP1和TRP2是不同的两个TRP，且TRP1和TRP2均对应同一个服务小区1。
N个参考信号资源集合与N个TRP标识的对应关系，可以为如下四种方式中的任意一种：
·TRP标识包括控制资源集索引标识(CORESET pool index)，控制资源集索引标识与TRP一一对应；
·TRP标识包括参考信号资源集合索引，参考信号资源集合索引与TRP一一对应；
·TRP标识包括参考信号资源索引，参考信号资源索引与TRP一一对应；
·TRP标识包括TRP编号。
步骤504：当至少两个参考信号资源集合中的第一参考信号资源集合中的参考信号满足波束失败条件时，终端确定第一参考信号资源集合对应的第一TRP 发生波束失败。
示意性的，波束失败条件包括：参考信号的无线链路质量低于门限值。
可选地，参考信号的无线链路质量采用：L1-参考信号接收功率(Reference Signal Received Power，RSRP)表征。可选地，参考信号的无线链路质量采用：L1-信干噪比(Signal-to-Interference-and-Noise Ratio，SINR)表征。
步骤506：在第一TRP发生波束失败时，终端向网络设备发送波束失败恢复请求。
波束失败恢复请求用于指示第一TRP发生波束失败，或者，用于指示存在TRP发生波束失败但是不指示是哪个TRP发生波束失败，在后续信令中再指示哪个TRP发生波束失败。
综上所述，本实施例提供的方法，通过在第一TRP发生波束失败时，由终端向网络设备发送波束失败恢复请求，能够在多个TRP发送的场景下的某一个TRP发生波束失败时，终端准确地向网络设备发送波束失败恢复请求。
在基于图5的可选实施例中，步骤506存在两种发送方式：
方式一，通过随机接入时频资源来发送波束失败恢复请求，如下图6所示实施例；
方式二，通过物理上行控制信道(Physical Uplink Control Channel，PUCCH)上承载的SR发送波束失败恢复请求，如下图7所示实施例。
针对波束失败恢复请求的第一种发送方式(随机接入时频资源)：
图6示出了本申请一个实施例提供的波束失败确定方法的流程图。该方法应用于图1所示的终端和网络设备中来举例说明。该方法包括：
步骤502：终端确定用于波束失败检测的N个参考信号资源集合，以及每个参考信号资源集合对应的TRP标识。
N个参考信号资源集合中存在不同的至少两个参考信号资源集合，至少两个参考信号资源集合对应的TRP标识不同，且至少两个参考信号资源集合对应的物理小区标识相同。
步骤504：当至少两个参考信号资源集合中的第一参考信号资源集合中的参考信号满足波束失败条件时，终端确定第一参考信号资源集合对应的第一TRP发生波束失败。
步骤506-1：终端在第一TRP发生波束失败时，在第一随机接入时频资源上发送第一随机接入前导码，第一随机接入前导码用于指示波束失败恢复请求。
在上述实施例中，步骤506-1为本申请实施例提供的一种波束失败时发送第一随机接入前导码的方法；步骤506-1可以单独被执行，也可以结合本公开中任意一个步骤一起执行。
波束失败恢复请求用于指示第一TRP发生波束失败，或者，用于指示存在TRP发生波束失败，但是不指示是哪个TRP发生波束失败，在后续信令中再指示哪个TRP发生波束失败。第一随机接入前导码是多个随机接入前导码中被分 配用于指示波束失败恢复请求的前导码。
本步骤包括但不限于如下实现方式中的至少一种：
·在第一TRP发生波束失败且第一TRP是PCell的TRP时，在第一随机接入时频资源上发送第一随机接入前导码；
·在第一TRP发生波束失败且第一TRP是PScell的TRP时，在第一随机接入时频资源上发送第一随机接入前导码。
在发生波束失败的TRP为PCell或PScell的TRP，且属于PCell或PScell的任意TRP发生波束失败时，都使用第一随机接入时频资源发送波束失败恢复请求。
·在第一TRP发生波束失败且第一TRP是PCell中配置了终端的CORESET#0的TRP时，在第一随机接入时频资源上发送第一随机接入前导码；
·在第一TRP发生波束失败且第一TRP是PScell中配置了终端的CORESET#0的TRP时，在第一随机接入时频资源上发送第一随机接入前导码。
需要说明的是，配置了终端的CORESET#0是表示在第一TRP发生波束失败之前，终端接收来自第一TRP的CORESET#0的指示信息。
针对第一随机时频资源：
示意性的，上述第一随机接入时频资源可以是第一TRP对应的随机接入时频资源，也可以是第二TRP对应的随机接入时频资源。随机接入时频资源，可简称为随机接入资源。
针对第一随机时频资源是第一TRP自身对应的随机接入时频资源的情形：
第一随机接入时频资源是第一TRP发送的第一SSB对应的随机接入时频资源。终端确定第一随机接入时频资源的方法可以包括：
1、第一TRP对应的CORESETpoolindex索引标识对应的至少一个CORESET的TCI状态对应的参考信号资源为第一SSB，将第一SSB的随机接入时频资源确定为第一随机接入时频资源。也即，第一SSB是第一TRP对应的CORESETpoolindex索引标识对应的至少一个CORESET的TCI状态对应的参考信号资源。
2、第一TRP对应的CORESETpoolindex索引标识对应的至少一个CORESET的TCI状态对应的参考信号资源为第一CSI-RS，第一SSB与第一CSI-RS对应，将第一SSB的随机接入时频资源确定为第一随机接入时频资源。也即，第一CSI-RS是第一TRP对应的CORESET索引标识对应的至少一个CORESET的TCI状态对应的参考信号资源。
3、网络设备直接指示了第一TRP对应的第一SSB，或，直接指示了第一TRP对应的CORESETpoolindex索引标识对应的第一SSB。
针对第一随机时频资源是其它TRP对应的随机接入时频资源的情形：
第一随机接入时频资源是第二SSB对应的随机接入时频资源，第二SSB是配置了终端的CORESET#0的TRP发送的SSB。配置了终端的CORESET#0的TRP与第一TRP可以相同，也可以不同。示意性的，若发生波束失败的第一TRP自身配置了CORESET#0，则优先使用自身的随机接入资源。
此时，所述方法还包括：
在两步随机接入过程中的消息A的PUSCH中发送标识信息，标识信息用于指示第一TRP的标识；或，在四步随机接入过程中的消息3的PUSCH中发送标识信息。
也即，终端通过消息A或消息1中的第一随机接入前导码通知网络设备发生了波束失败，还通过消息A或消息3通知网络设备发生了波束失败的TRP是第一TRP。
示意性的，标识信息包括如下至少之一：
第一TRP对应的控制资源集索引标识；
第一TRP对应的参考信号资源集合索引或参考信号资源索引；
第一TRP的标识；
第一TRP的小区标识。
示意性的，参考信号资源包含：SSB、CSI-RS、PRS、TRS、SRS中的至少一种。
示意性的，第一TRP包含一个或多个TRP，第一TRP包含多个TRP时，需要指示第一TRP中每个TRP的标识信息。多个TRP可以属于不同小区；多个TRP也可以属于同一小区，当多个TRP属于同一小区时，如果该小区还有没发生波束失败的TRP，那么指示发生了波束失败的多个TRP的标识信息；当该小区内所有TRP发生波束失败时，可以分别指示发生了波束失败的多个TRP的标识信息或者直接指示该小区的标识信息。
在一个可选的实现方式中，网络设备还向终端配置有用于发现候选波束的第二参考信号资源集合，当第二参考信号资源集合中存在参考信号的无线链路质量大于门限值时，确定该参考信号对应的候选波束为目标候选波束。
也即，目标候选波束对应的参考信号的无线链路质量大于门限值，该参考信号是用于发现候选波束的第二参考信号资源集合中的参考信号。无线链路质量采用L1-RSRP或L1-SINR来表示。
此时，第一随机接入时频资源是与目标候选波束对应的SSB对应的随机接入时频资源。
示意性的，目标候选波束对应的SSB是由第一TRP或第二TRP发送的SSB。当目标候选波束对应的SSB是第二TRP发送的SSB时，终端还在两步随机接入过程中的消息A的PUSCH中发送标识信息，标识信息用于指示第一TRP；或，在四步随机接入过程中的消息3的PUSCH中发送标识信息。
步骤508：网络设备在第一随机接入时频资源上接收第一随机接入前导码；
网络设备在接收到终端发送的第一随机接入前导码后，确定终端发生了波束失败。
步骤510：网络设备确定第一TRP。
在第一随机接入时频资源是第一SSB的随机接入时频资源时，网络设备根据第一随机接入时频资源对应的第一SSB，确定第一TRP发生波束失败。
其中，第一SSB与第一TRP存在对应关系。比如，第一SSB是第一TRP对应的CORESETpoolindex索引标识对应的至少一个CORESET的TCI状态对应的参考信号资源。又比如，第一SSB与第一CSI-RS对应，将第一SSB的随 机接入时频资源确定为第一随机接入时频资源。也即，第一CSI-RS是第一TRP对应的CORESETpoolindex索引标识对应的至少一个CORESET的TCI状态对应的参考信号资源。再比如，网络设备直接指示了第一TRP对应的第一SSB，或，直接指示了第一TRP对应的CORESETpoolindex索引标识对应的第一SSB。
在第一随机接入时频资源是第二SSB或其它TRP发送的SSB的情况下，网络设备还在两步随机接入过程中的消息A的PUSCH中接收标识信息，根据标识信息确定第一TRP；或，网络设备在四步随机接入过程中的消息3的PUSCH中接收标识信息，网络设备根据标识信息确定第一TRP。
在一个可选的实现方式中，网络设备还向终端配置有用于发现候选波束的第二参考信号资源集合。在第一随机接入时频资源是是与目标候选波束对应的SSB对应的随机接入时频资源时，网络设备根据第一随机接入时频资源对应的SSB，确定出目标候选波束。
步骤512：网络设备针对第一TRP，为终端进行波束失败恢复。
在存在终端上报的目标候选波束时，网络设备根据目标候选波束为终端进行波束失败恢复，比如将目标候选波束指定为恢复后的波束。在不存在终端上报的目标候选波束时，由网络设备自行指定波束为恢复后的波束，或网络设备指示终端进行波束管理测量和上报，并基于上报结果指定恢复后的波束。
综上所述，本实施例提供的方法，通过在第一TRP发生波束失败时，终端采用第一随机接入时频资源发送第一随机接入前导码，同时通过第一随机接入时频资源或标识信息来指示第一TRP，从而使得网络设备能够准确获知第一TRP发生了波束失败，网络设备能够针对第一TRP为终端进行波束失败恢复。
