Description

波束失败检测资源分配方法、装置及存储介质 技术领域
本公开涉及通信技术领域，尤其涉及波束失败检测资源分配方法、装置及存储介质。
背景技术
在新无线技术(New Radio，NR)通信系统中，为了保证覆盖范围以及抵抗路径损耗，通常需要基于波束(beam)进行数据的发送和接收。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，当终端发生移动，或者天线方向发生旋转时，当前配置给终端用于发送和接收的波束可能会出现波束失败的问题。
相关技术中，终端使用成员载波(Component Carrier，CC)/带宽部分(bandwidth part，BWP)控制信道资源集合(CORESET)的准共址(quasi co-location，QCL)的传输配置(transmission configuration indication，TCI)状态对应的参考信号(Reference Signal，RS)作为波束失败检测的资源。用于检测波束失败的RS资源也称为波束失败检测(beam failure detection，BFD)RS资源。其中，若终端检测到BFD RS资源中全部BFD RS的信道质量都低于预设阈值，则说明发生了波束失败。
目前，能够供终端选择作为BFD RS的RS资源数量可能会多于终端支持配置的RS资源数量，此种情况下如何选择用于波束失败检测的RS资源，是需要解决的问题。
发明内容
为克服相关技术中存在的问题，本公开提供一种波束失败检测资源分配方法、装置及存储介质。
根据本公开实施例的第一方面，提供一种波束失败检测资源分配方法，包括确定网络设备为终端配置的控制信道资源集合；在所述控制信道资源集合的数量大于终端支持的波束失败检测资源数量时，选择所述波束失败检测资源数量个目标控制信道资源集合；将选择的目标控制信道资源集合的准共址传输配置状态对应的参考信号资源，作为波束失败检测参考信号资源。
根据本公开实施例的第二方面，提供一种波束失败检测资源分配装置，包括确定单元，被配置为确定网络设备为终端配置的控制信道资源集合；选择单元，被配置为在所述控制信道资源集合的数量大于终端支持的波束失败检测资源数量时，选择所述波束失败检测资 源数量个目标控制信道资源集合；检测单元，被配置为将选择的目标控制信道资源集合的准共址传输配置状态对应的参考信号资源，作为波束失败检测参考信号资源。
本公开的实施例提供的技术方案可以包括以下有益效果：在控制信道资源集合的数量大于终端支持的波束失败检测资源数量时，选择终端支持的波束失败检测资源数量个目标控制信道资源集合，并将选择的目标控制信道资源集合的准共址传输配置状态对应的参考信号资源，作为波束失败检测参考信号资源，实现用于波束失败检测的RS资源的确定。
应当理解的是，以上的一般描述和后文的细节描述仅是示例性和解释性的，并不能限制本公开。

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。
本公开实施例提供的波束失败请求资源分配方法可应用于图1所示的无线通信系统中。参阅图1所示，该无线通信系统中包括网络设备和终端。终端通过无线资源与网络设备相连接，并进行数据传输。
可以理解的是，图1所示的无线通信系统仅是进行示意性说明，无线通信系统中还可包括其它网络设备，例如还可以包括核心网设备、无线中继设备和无线回传设备等，在图 1中未画出。本公开实施例对该无线通信系统中包括网络设备数量和终端数量不做限定。
进一步可以理解的是，本公开实施例无线通信系统，是一种提供无线通信功能的网络。无线通信系统可以采用不同的通信技术，例如码分多址(code division multiple access,CDMA)、宽带码分多址(wideband code division multiple access，WCDMA)、时分多址(time division multiple access，TDMA)、频分多址(frequency division multiple access，FDMA)、正交频分多址(orthogonal frequency-division multiple access，OFDMA)、单载波频分多址(single Carrier FDMA，SC-FDMA)、载波侦听多路访问/冲突避免(Carrier Sense Multiple Access with Collision Avoidance)。根据不同网络的容量、速率、时延等因素可以将网络分为2G(英文：generation)网络、3G网络、4G网络或者未来演进网络，如5G网络，5G网络也可称为是新无线网络(New Radio，NR)。为了方便描述，本公开有时会将无线通信网络简称为网络。
进一步的，本公开中涉及的网络设备也可以称为无线接入网设备。该无线接入网设备可以是：基站、演进型基站(evolved node B，基站)、家庭基站、无线保真(wireless fidelity，WIFI)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等，还可以为NR系统中的gNB，或者，还可以是构成基站的组件或一部分设备等。应理解，本公开的实施例中，对网络设备所采用的具体技术和具体设备形态不做限定。在本公开中，网络设备可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域(小区)内的终端进行通信。此外，当为车联网(V2X)通信系统时，网络设备还可以是车载设备。
进一步的，本公开中涉及的终端，也可以称为终端设备、用户设备(User Equipment，UE)、移动台(Mobile Station，MS)、移动终端(Mobile Terminal，MT)等，是一种向用户提供语音和/或数据连通性的设备，例如，终端可以是具有无线连接功能的手持式设备、车载设备等。目前，一些终端的举例为：智能手机(Mobile Phone)、口袋计算机(Pocket Personal Computer，PPC)、掌上电脑、个人数字助理(Personal Digital Assistant，PDA)、笔记本电脑、平板电脑、可穿戴设备、或者车载设备等。此外，当为车联网(V2X)通信系统时，终端设备还可以是车载设备。应理解，本公开实施例对终端所采用的具体技术和具体设备形态不做限定。
在NR中，特别是通信频段在frequency range 2时，由于高频信道衰减较快，为了保证覆盖范围，终端和网络设备之间需要使用基于波束(beam)的发送和接收。
在NR中，由于控制信道也需要使用基于波束的发送和接收，当终端发生移动，或者天线方向发生旋转时，当前配置给终端用于发送和接收的波束可能会出现问题，即出现了波束失败的问题。例如，当前配置给终端的用于发送接收物理下行控制信道(physical downlink control channel，PDCCH)的发射波束或接收波束可能会出现问题，即出现了beam failure的问题。目前标准定义了用于检测beam failure的RS资源。用于检测beam failure的RS资源也称为波束失败检测(beam failure detection，BFD)RS资源。其中，若终端检测到BFD RS资源中全部BFD RS的信道质量都低于预设阈值，则说明发生了beam failure。
相关技术中，BFD RS资源可以由网络设备为终端配置，例如网络设备为终端配置2个或3个BFD RS资源。在网络设备没有为终端配置BFD RS资源时，终端可以使用成员载波(Component Carrier，CC)/带宽部分(bandwidth part，BWP)控制信道资源集合(CORESET)的准共址(quasi co-location，QCL)的传输配置(transmission configuration indication，TCI)状态对应的RS资源作为BFD RS资源。然而，针对单个发送接收点(transmission-reception point，TRP)，在每个CC/BWP上，网络设备最多可以给终端配置3个控制信道资源集合(CORESET)，每个CORESET对应一个TCI状态。而针对多TRP(multi-TRP)在每个CC/BWP上，网络设备最多可以给终端配置5个CORESET，每个CORESET对应一个TCI状态。即，能够供终端选择作为BFD RS的RS资源数量可能会多于终端支持配置的RS资源数量，此种情况下如何选择用于波束失败检测的RS资源，是需要解决的问题。
有鉴于此，本公开实施例提供一种波束失败检测资源分配方法，在该波束失败检测资源分配方法中，在CORESET的数量大于终端支持的BFD RS资源数量时，选择匹配BFD RS资源数量的目标CORESET，并将选择的目标CORESET的QCL的TCI状态对应的RS资源作为BFD RS资源。例如，网络设备为终端配置的终端支持的BFD RS资源数量为2，但是网络设备并未给终端配置对应的BFD RS资源时，终端可以在3个CORESET或5个CORESET中针对每个TRP选择2个CORESET作为目标CORESET，并使用2个目标CORESET的QCL的TCI状态对应的RS资源作为BFD RS资源。
图2是根据一示例性实施例示出的一种BFD RS资源分配方法的流程图，如图2所示，BFD RS资源分配方法用于终端中，包括以下步骤。
在步骤S11中，确定网络设备为终端配置的CORESET。
本公开实施例中网络设备为终端配置的CORESET可以是3个，也可以是5个。例如， 针对单个TRP，在每个CC/BWP上，网络设备最多可以给终端配置3个CORESET，每个CORESET对应一个TCI状态。而针对multi-TRP，在每个CC/BWP上，网络设备最多可以给终端配置5个CORESET。
在步骤S12中，在CORESET的数量大于终端支持的BFD RS资源数量时，选择BFD RS资源数量个目标CORESET。
通常，终端支持的BFD RS资源数量为2个或3个。在终端支持的BFD RS资源数量为2个时，单TRP配置3个CORESET数量的情况以及multi-TRP配置5个CORESET数量的情况，均可以理解为是CORESET的数量大于终端支持的BFD RS资源数量。
在CORESET的数量大于终端支持的BFD RS资源数量时，选择BFD RS资源数量个目标CORESET。例如，终端支持的BFD RS资源数量最大为2，但是网络设备并未给终端配置对应的BFD RS资源时，但网络设备给终端配置了3个CORESET或5个CORESET，那么终端可以在3个CORESET或5个CORESET中针对每个TRP选择2个CORESET作为目标CORESET。
在步骤S13中，将选择的目标CORESET的QCL的TCI状态对应的RS资源作为BFD RS资源。
例如上述示例中，本公开实施例中可以使用2个目标CORESET的QCL的TCI状态对应的RS资源作为BFD RS资源。
本公开实施例中，在CORESET的数量大于终端支持的BFD RS资源数量时，选择匹配BFD RS资源数量的目标CORESET，并将选择的目标CORESET的QCL的TCI状态对应的RS资源作为BFD RS资源，实现CORESET的数量大于终端支持的BFD RS资源数量时BFD RS资源的确定。
本公开实施例中，在多个CORESET中选择终端支持的BFD RS资源数量的目标CORESET时，可以对终端配置的多个CORESET进行分组，将属于同一TRP的CORESET划分为一组，然后依据分组后每一组内的CORESET的数量选择目标CORESET。
图3是根据一示例性实施例示出的一种选择终端支持的BFD RS资源数量的目标CORESET的实施流程图。参阅图3所示，包括如下步骤。
在步骤S121中，对终端配置的多个CORESET进行分组，将属于同一TRP的CORESET划分为一组。
在步骤S122中，依据分组后每一组内的CORESET的数量选择目标CORESET。
本公开实施例中，在对终端配置的多个CORESET进行分组时，可以通过CORESET 中是否配置有高层信令标识(higher layer signaling index)区分是否属于同一TRP并进行分组，以便将属于同一TRP的CORESET划分为一组。对CORESET进行分组后，可以针对每一TRP分别进行目标CORESET的选择。
图4是根据一示例性实施例示出的一种对终端配置的多个CORESET进行分组的流程图。参阅图4所示，包括如下步骤。
在步骤S1211中，判断配置的CORESET是否配置有higher layer signaling index。
若CORESET配置有higher layer signaling index则执行步骤S1212a。若CORESET未配置higher layer signaling index，则执行步骤S1212b。
在步骤S1212a中，若CORESET配置有higher layer signaling index，则将配置有同一higher layer signaling index的CORESET划分为同一组；
在步骤S1212b中，若CORESET未配置higher layer signaling index，则将全部的CORESET划分为一组。
本公开实施例中对CORESET进行分组后，可针对得到的各CORESET组内的CORESET数量，选择目标CORESET。一种实施方式中，在组内CORESET数量小于或等于终端支持的BFD RS资源数量时，选择组内的全部CORESET作为目标CORESET。另一种实施方式中，在组内CORESET数量大于终端支持的BFD RS资源数量时，按照指定优先级顺序选择终端支持的BFD RS资源数量个CORESET为目标CORESET。
本公开实施例中上述指定优先级顺序可以是预先设定的，例如可以是如下优先级顺序中的一种或多种：CORESET标识(ID)序号从小到大的优先级顺序；小区级别搜索空间(cell common search space)CORESET、用户组级别搜索空间(group common search space)CORESET和用户指定搜索空间(user specific search space)CORESET的优先级从高到低的优先级顺序；终端监测CORESET周期时长从小到大的优先级顺序。
本公开实施例中以终端支持的BFD RS资源数量为2个，组内CORESET数量为3个的情况为例进行说明。
按照CORESET ID序号从小到大的优先级顺序进行目标CORESET选择时，选择CORESET ID小的，丢弃CORESET ID最大的。比如CORESET ID为0，1，2，则选择CORESET ID为0，1的，丢弃CORESET ID为2的。当然，本公开实施例中，也可以按照CORESET ID序号从大到小的优先级顺序进行目标CORESET选择，即选择CORESET ID大的，丢弃CORESET ID最小的。
按照cell common search space CORESET、group common search space CORESET和 user specific search space CORESET的优先级从高到低的优先级顺序进行目标CORESET选择时，针对小区内所有终端的CORESET的优先级最高，例如，用于指示SIB1的时频资源的Type0-PDCCH CSS set，用于指示其它系统信息时频资源的Type0A-PDCCH CSS set，用于指示随机接入资源的Type1-PDCCH CSS set，用于指示寻呼时频资源的Type2-PDCCH CSS set等优先级最高，优先选择cell common search space CORESET作为目标CORESET。用于指示终端传输的时隙格式和功率控制的Type3-PDCCH CSS set等针对一组终端的CORESET优先级其次。针对某个特定终端的user specific search space CORESET优先级最低。即选择cell common search space CORESET和group common search space CORESET，丢弃user specific search space CORESET。当然，本公开实施例中，也可以是按照user specific search space CORESET、group common search space CORESET和cell common search space CORESET优先级从高到低的优先级顺序进行目标CORESET选择。例如，可以选择user specific search space CORESET和group common search space CORESET，丢弃cell common group common search space CORESET。
本公开实施例中按照终端监测CORESET周期时长从小到大的优先级顺序选择目标CORESET时，可以选择终端监测CORESET周期时长最小的两个CORESET。由于网络设备会配置终端去监测每个CORESET，故周期越小监测越频繁，所以本公开实施例中选择周期最小的两个CORESET作为目标CORESET。当然，本公开实施例中也可以按照终端监测CORESET周期时长从大到小的优先级顺序选择目标CORESET，即选择监测CORESET周期时长最大的两个CORESET作为目标CORESET。
可以理解的是，本公开上述实施例中按照指定优先级顺序进行目标CORESET选择的实施过程，可以适用于单个TRP配置的CORESET数量大于终端支持的BFD RS资源数量的情况。例如，单个TRP配置的CORESET数量为3个，终端支持的BFD RS资源数量为2个的情况下，可按照上述优先级顺序进行目标CORESET的选择，并将选择的目标CORESET的QCL的TCI状态对应的RS资源作为BFD RS资源。
进一步可以理解的是，本公开上述实施例中对CORESET按照higher layer signaling index进行分组，并按照分组后的CORESET数量选择目标CORESET的实施方式，可以适用于multi-TRP配置的CORESET数量大于终端支持的BFD RS资源数量的情况。
本公开上述实施例中提供的BFD RS资源分配方法，在终端配置的CORESET数量大于终端支持的BFD RS资源数量时，选择匹配终端支持的BFD RS资源数量的CORESET作为目标CORESET，并将选择的目标CORESET的QCL的TCI状态对应的RS资源作为 BFD RS资源，实现用于BFD RS资源的确定。
基于相同的构思，本公开实施例还提供一种BFD RS资源分配装置。
可以理解的是，本公开实施例提供的BFD RS资源分配装置为了实现上述功能，其包含了执行各个功能相应的硬件结构和/或软件模块。结合本公开实施例中所公开的各示例的单元及算法步骤，本公开实施例能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设计约束条件。本领域技术人员可以对每个特定的应用来使用不同的方法来实现所描述的功能，但是这种实现不应认为超出本公开实施例的技术方案的范围。
图5是根据一示例性实施例示出的一种BFD RS资源分配装置框图。参照图5，该BFD RS资源分配装置100包括确定单元101、选择单元102和检测单元103。
确定单元101被配置为确定网络设备为终端配置的CORESET。选择单元102，被配置为在CORESET的数量大于终端支持的BFD RS资源数量时，选择BFD RS资源数量个目标CORESET。检测单元103，被配置为将选择的目标CORESET的QCL的TCI状态对应的RS资源，作为BFD RS资源。
一种实施方式中，选择单元102，被配置为采用如下方式选择BFD RS资源数量个目标CORESET：对配置的CORESET进行分组，其中，属于同一TRP的CORESET划分为一组。依据分组后每一组内的CORESET数量选择目标CORESET。
另一种实施方式中，选择单元102被配置为采用如下方式对配置的CORESET进行分组：判断配置的CORESET是否配置有higher layer signaling index。若CORESET配置有higher layer signaling index，则将配置有同一higher layer signaling index的CORESET划分为同一组。若CORESET未配置higher layer signaling index，则将全部的CORESET划分为一组。
又一种实施方式中，选择单元102采用如下方式依据分组后每一组内的CORESET数量选择目标CORESET：
在组内CORESET数量小于或等于终端支持的BFD RS资源数量时，选择组内的全部CORESET为目标CORESET。在组内CORESET数量大于终端支持的BFD RS资源数量时，按照指定优先级顺序选择BFD RS资源数量个CORESET为目标CORESET。
其中，指定优先级顺序包括以下一种或多种：CORESET ID序号从小到大的优先级顺序。cell common search space CORESET、group common search space CORESET和user specific search space CORESET的优先级从高到低的优先级顺序。终端监测CORESET周 期时长从小到大的优先级顺序。
