Description

波束失败检测参考信号资源的确定方法、装置及存储介质
本申请要求2022年10月28日提交的申请号为PCT/CN2022/128420、发明名称为“波束失败检测参考信号资源的确定方法、装置及存储介质”的发明专利申请的优先权。以上专利申请的全部公开内容以引用方式并入于此。
技术领域
本公开涉及通信技术领域，尤其涉及一种波束失败检测参考信号资源(Beam failure detection reference signal，BFD-RS)的确定方法、装置及存储介质。
背景技术
在新无线技术(New Radio，NR)中，例如通信频段在frequency range 2时，由于高频信道衰减较快，为了保证覆盖范围，需要使用基于波束(beam)的发送和接收。但是，由于信道的突然波动、故障或中断，建筑物的遮挡、终端的移动等因素的影响，有时会发生波束失败，此时终端需要进行波束失败检测。
相关技术中，网络设备通过为终端配置波束失败检测参考信号资源集合(beam failure detection reference signal set，BFD-RS set)进行波束失败检测。如果网络设备没有显式的配置BFD-RS set，终端会根据网络设备为终端配置的控制资源集(Control Resource Set，CORESET)的传输配置指示(Transmission Configuration Indication，TCI)状态对应的信道状态信息参考信号(Channel-Slate Information Reference Signal，CSI-RS)来确定BFD-RS set。
当网络设备有多个发送接收点(Transmission Reception Point，TRP)，并使用多个TRP为终端发送PDCCH时，单个下行控制信令(single downlink control information，S-DCI)可以使用多个波束发送。在针对多个波束发送同一DCI信令的场景中，终端如何确定BFD-RS set，是需要解决的问题。

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。
本公开实施例提供的波束失败检测参考信号资源的确定方法可应用于图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)、客户前置设备(Customer Premise Equipment，CPE)，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。
在新无线技术(New Radio，NR)中，例如通信频段在frequency range 2时，由于高频信道衰减较快，为了保证覆盖范围，需要使用基于波束(beam)的发送和接收。
终端对于物理下行控制信道(Physical Downlink Control Channel，PDCCH)接收，通过基站为控制资源集Control Resource Set，CORESET)配置传输配置指示(Transmission Configuration Indication，TCI)状态来指示PDCCH的准共址(Quasi co-location，或Quasi co-located，QCL)信息。其中，准共址信息包括QCL Type D，即接收空间参数，俗称波束。终端在获得了CORESET的TCI state之后，由于信道的突然波动、故障或中断，建筑物的遮挡、终端的移动等因素的影响，导致当前的TCI state不合适，有时会发生波束失败，此时终端需要进行波束失败检测。
相关技术中，网络设备通过为终端配置波束失败检测参考信号资源集合(beam failure  detection reference signal set，BFD-RS set)进行波束失败检测。当针对小区进行波束失败检测时，针对一个服务小区的一个带宽部分(BandWidth Part，BWP)，配置一个参考信号集合q0。当针对TRP进行失败检测时，针对一个服务小区的一个BWP，配置两个参考信号集合(q0，0)和(q0，1)。如果网络设备没有显式的为终端配置q0，终端会根据网络设备为终端配置的CORESET的TCI state对应的信道状态信息参考信号(Channel-Slate Information Reference Signal，CSI-RS)来确定BFD-RS set。如果网络设备没有显式的为终端配置(q0，0)和(q0，1)，终端终端先基于CORESET池索引Pool Index确定两组CORESET，再针对每组CORESET中所有CORESET的TCI state对应的CSI-RS确定各组用于失败检测的资源。
当网络设备有多个发送接收点(Transmission Reception Point，TRP)且基于多个下行控制信令(Multi downlink control information，M-DCI)，并使用多个TRP为终端发送PDCCH时，每个TRP通过各自对应的DCI发送与各自TRP相关的传输资源指示以及TCI state。而多个CORESET中每个CORESET会配置一个CORESET Pool Index，不同CORESET Pool Index对应不同TRP。此时，BFD-RS set可以根据CORESET Pool Index包含的CORESET来确定。
当网络设备有多个TRP且基于单个下行控制信令(single downlink control information，S-DCI)，并使用多个TRP为终端发送PDCCH时，S-DCI可以使用多个波束发送，S-DCI发送多个TRP相关的传输资源指示以及TCI state，终端不知道哪个DCI是哪个TRP发送的。
因此，在针对多个波束发送同一DCI信令的场景中，终端如何确定BFD-RS set，是需要解决的问题。
基于此，本公开实施例提供一种波束失败检测参考信号资源的确定方法，终端接收网络设备发送的第一配置信息，其中，第一配置信息用于配置至少一个CORESET，至少一个CORESET对应至少一个TCI状态。从而终端可以基于至少一个CORESET对应的至少一个TCI状态，确定至少一个BFD-RS set包含的参考信号，进一步的对BFD-RS set包含的参考信号进行波束失败检测，提高基于多TRP的波束失败恢复成功率。
图2是根据一示例性实施例示出的一种波束失败检测参考信号资源的确定方法的流程图，如图2所示，波束失败检测参考信号资源的确定方法用于终端中，包括以下步骤。
在步骤S11中，接收网络设备发送的第一配置信息，第一配置信息用于配置至少一个CORESET，至少一个CORESET对应至少一个TCI状态。
在步骤S12中，基于至少一个CORESET对应的至少一个TCI状态，确定至少一个BFD-RS set包含的参考信号。
其中，至少一个CORESET中每一个CORESET对应至少一个TCI状态。至少一个TCI状态中每一个TCI状态包含有一个参考信号，一个或多个TCI状态包含的参考信号构成一个BFD-RS set。
在本公开实施例中，终端接收网络设备发送的第一配置信息，其中，第一配置信息用于配置至少一个CORESET，至少一个CORESET对应至少一个TCI状态。从而终端可以基于至少一个CORESET对应的至少一个TCI状态，确定至少一个BFD-RS set包含的参考信号，进一步的对BFD-RS set包含的参考信号进行波束失败检测，提高基于多TRP的波束失败恢复成功率。
一些实施例中，BFD-RS set包含的参考信号为至少一个TCI状态指示的QCL Type D对应的参考信号。
在本公开实施例提供的一种波束失败检测参考信号资源的确定方法中，至少一个CORESET中每个CORESET具有对应的CORESET组，基于CORESET组中至少一个CORESET对应的至少一个TCI状态，确定至少一个BFD-RS set包含的参考信号。如图3所示，图3是根据一示例性实施例示出的一种波束失败检测参考信号资源的确定方法的流程图，包括以下步骤。

在本公开实施例中，基于CORESET组中至少一个CORESET对应的至少一个TCI状态，确定至少一个BFD-RS set包含的参考信号，进一步的终端能够对每个BFD-RS set包含的参考信号进行波束失败检测，提高基于多TRP的波束失败恢复成功率。
图4是根据一示例性实施例示出的一种波束失败检测参考信号资源的确定方法的流程图，如图4所示，包括以下步骤。
在步骤S31中，接收网络设备发送的第一配置信息，第一配置信息用于配置至少一个CORESET，至少一个CORESET对应至少一个TCI状态。
在步骤S32中，确定至少一个CORESET中每个CORESET具有对应的CORESET组。
在步骤S33中，基于CORESET组中至少一个CORESET对应的至少一个TCI状态，确定至少一个BFD-RS set包含的参考信号。
在本公开实施例中，确定至少一个CORESET中每个CORESET具有对应的CORESET组，并基于CORESET组中至少一个CORESET对应的至少一个TCI状态，确定至少一个 BFD-RS set包含的参考信号，进一步的终端能够对每个BFD-RS set包含的参考信号进行波束失败检测，提高基于多TRP的波束失败恢复成功率。
在本公开实施例中，步骤S32中，确定至少一个CORESET中每个CORESET具有对应的CORESET组，进一步的在步骤S33中终端可以基于CORESET组中至少一个CORESET对应的至少一个TCI状态，确定至少一个BFD-RS set包含的参考信号。而确定至少一个CORESET中每个CORESET具有对应的CORESET组的方法可以有很多种方式，本公开实施例中通过以下实施例所述的多个方案对这些方式分别进行说明。需要说明，本公开实施例中的多个方案是可以各自独立被实施例的，也可以是其中的任意一个实施例结合其他实施例一起被实施。
在本公开实施例提供的一种波束失败检测参考信号资源的确定方法中，至少一个CORESET对应至少一个TCI状态，至少一个CORESET中不同CORESET类型的CORESET对应的TCI状态不同。
其中，一个CORESET对应一种CORESET类型，至少一个CORESET对应一种CORESET类型或多种CORESET类型，至少一个CORESET中不同的CORESET对应相同的CORESET类型或不同的CORESET类型。
在一些实施例中，至少一个CORESET对应至少一个TCI状态，包括以下至少一项：
一.至少一个CORESET中第一CORESET类型的CORESET对应第一TCI状态和第二TCI状态；
二.至少一个CORESET中第二CORESET类型的CORESET对应第一TCI状态和第二TCI状态中的第一个TCI状态；
三.至少一个CORESET中第三CORESET类型的CORESET对应第一TCI状态和第二TCI状态中的第二个TCI状态；
四.至少一个CORESET中第四CORESET类型的CORESET对应第三TCI状态。
在本公开实施例中，至少一个CORESET对应至少一个TCI状态可以包括上述一至四中的任意一项或多项，具有多种组合形式，本公开实施例对此不进行限定，也不再一一列举。
其中，第二CORESET类型的CORESET对应第一TCI状态和第二TCI状态中的第一个TCI状态可以为第一TCI状态和第二TCI状态中的任意一个TCI状态。第三CORESET类型的CORESET对应第一TCI状态和第二TCI状态中的第二个TCI状态与第二CORESET类型的CORESET对应的TCI状态不同。
在本公开实施例中除另有说明外，第一TCI状态和第二TCI状态均指统一(unified)传 输配置指示状态(indicated Transmission Configuration Indicator，indicated TCI state)。indicated TCI state可以适用于终端的至少两项信道和/或其解调参考信号(Demodulation Reference Signal，DMRS)的传输。其中两项信道是指PDCCH，物理下行共享信道(Physical Downlink Shared Channel，PDSCH)，物理下行控制信道(Physical Downlink Control Channel，PDCCH)和物理上行共享信道(Physical Uplink Shared Channel，PUSCH)中的至少两项。
其中，第一TCI状态和第二TCI状态可以包括上下行联合(joint)TCI状态，和/或，下行(DL)TCI状态。
在本公开实施例中，每个CORESET具有对应的TCI状态和CORESET类型，通过为不同CORESET配置不同的TCI状态，以便终端可以基于至少一个CORESET对应的至少一个TCI状态，确定至少一个BFD-RS set包含的参考信号，进一步的对BFD-RS set包含的参考信号进行波束失败检测，提高基于多TRP的波束失败恢复成功率。
在本公开实施例提供的一种波束失败检测参考信号资源的确定方法中，CORESET组基于至少一个CORESET的CORESET组标识或CORESET池索引确定；或，CORESET组基于至少一个CORESET的CORESET类型确定。
一示例性实施方式中，当CORESET组基于至少一个CORESET的CORESET组标识或CORESET池索引确定时，由于至少一个CORESET的CORESET组标识或CORESET池索引为网络设备配置，因此在本公开实施例中可以认为CORESET组由网络设备配置。
