Description

传输配置指示状态的确定方法、装置及存储介质 技术领域
本公开涉及通信技术领域，尤其涉及一种传输配置指示状态(Transmission Configuration Indicator，TCI)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。
相关技术中，为减少信令开销，引入了统一传输配置指示状态(unified Transmission Configuration Indicator，unified TCI state)的使用。统一TCI状态可以是上行和下行分开指示，或者上下行联合指示。即网络设备如果指示一个用于下行的TCI状态，那么该TCI状态可以适用于终端的物理下行共享信道(Physical Downlink Shared Channel，PDSCH)和/或其相应的DMRS、和至少一部分物理下行控制信道(Physical Downlink Control Channel，PDCCH)和/或其相应的DMRS，以及至少一部分信道状态信息参考信号(Channel State Information-Reference Signal，CSI-RS)。网络设备如果指示一个用于上行的TCI状态，那么该TCI状态可以适用于终端的物理上行共享信道(Physical Uplink Shared Channel，PUSCH)和/或其相应的DMRS、和至少一部分物理上行控制信道(Physical Uplink Control Channel，PUCCH)和/或其相应的DMRS，以及一部分探测参考信号(Sounding Reference Signal，SRS)。网络设备如果指示一个联合TCI状态，则该联合TCI状态可以同时适用于上行和下行信道和/或参考信号。

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。
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。
相关技术中，为减少信令开销，引入了统一传输配置指示状态(unified Transmission Configuration Indicator，unified TCI state)的使用。统一TCI状态可以是上行和下行分开指示，或者上下行联合指示。即网络设备如果指示一个用于下行的TCI状态，那么该TCI状态可以适用于终端的物理下行共享信道(Physical Downlink Shared Channel，PDSCH)和/或其相应的DMRS、和至少一部分物理下行控制信道(Physical Downlink Control Channel，PDCCH)和/或其相应的DMRS，以及至少一部分信道状态信息参考信号(Channel State Information-Reference Signal，CSI-RS)。网络设备如果指示一个用于上行的TCI状态，那么该TCI状态可以适用于终端的物理上行共享信道(Physical Uplink Shared Channel，PUSCH)和/或其相应的DMRS、和至少一部分物理上行控制信道(Physical Uplink Control Channel，PUCCH)和/或其相应的DMRS，以及至少一部分探测参考信号(Sounding Reference Signal，SRS)。网络设备如果指示一个联合TCI状态，则该联合TCI状态可以同时适用于上行和下行信道和/或参考信号。
相关技术只适用于单发送接收点(Single Transmission Reception Point，S-TRP)的情况。
发明人注意到，在多发送接收点(Multi Transmission Reception Point，M-TRP)场景下，对于配置了具有链接关系的两个搜索空间集(Search Space set，SS set)来说，若指示多个TCI状态时，两个搜索空间集可以分别采用一个TCI状态。但如果仅指示了一个TCI状态时，被配置了链接关系的两个搜索空间集内PDCCH候选集的监测如何进行，是需要解决的问题。
本公开实施例提供的TCI状态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。
相关技术中，PDCCH和/或PDCCH的DMRS、PDSCH和/或PDSCH的DMRS、PUCCH和/或PUCCH的DMRS、PUSCH和/或PUSCH的DMRS，和/或参考信号等利用的波束都是被独立指示的。其中，参考信号可以包括CSI-RS、SRS、定位参考信号(Positioning Reference Signal，PRS)，相位参考信号(tracking reference signal，TRS)等等。例如，CSI-RS 可以包括用于信道状态信息测量的CSI-RS、用于波束测量的CSI-RS或用于路径损失估计的CSI-RS。SRS可以包括用于基于码本或非码本的信道状态信息测量的SRS、用于波束测量的SRS或用于定位测量的SRS。
通常情况下，PDCCH和/或PDCCH的DMRS，以及PUCCH和/或PUCCH的DMRS分别通过MAC CE来激活一个波束，而PDSCH和/或PDSCH的DMRS，以及PUSCH和/或PUSCH的DMRS分别通过DCI信令来指示各自对应的波束。
这里的波束可以通过TCI状态或spatialrelationinfo(空间关系)来指示。其中PDCCH对应的TCI状态包含PDCCH和/或其DMRS对应的TCI状态，即该TCI状态用于PDCCH和/或其DMRS的接收。同理，PDSCH对应的TCI状态包含PDSCH和/或其DMRS对应的TCI状态，即该TCI状态用于PDSCH和/或其DMRS的接收；PUCCH对应的TCI状态或spatialrelationinfo包含PUCCH和/或其DMRS对应的TCI状态或spatialrelationinfo，即该TCI状态或spatialrelationinfo用于PUCCH和/或其DMRS的发送；PUSCH对应的TCI状态或spatialrelationinfo包含PUSCH和/或其DMRS对应的TCI状态或spatialrelationinfo，即该TCI状态或spatialrelationinfo用于PUSCH和/或其DMRS的发送。
进一步的，为减少信令开销，另一种相关技术中，引入了统一传输配置指示状态(unified Transmission Configuration Indicator，unified TCI state)的使用。统一TCI状态可以是上行和下行分开指示，或者上下行联合指示。即网络设备如果指示一个用于下行的TCI状态(DL TCI state)，那么该TCI状态可以适用于终端的物理下行共享信道(Physical Downlink Shared Channel，PDSCH)和/或其相应的DMRS，和至少一部分物理下行控制信道(Physical Downlink Control Channel，PDCCH)，以及一部分信道状态信息参考信号(Channel State Information-Reference Signal，CSI-RS)。网络设备如果指示一个用于上行的TCI状态(UL TCI state)，那么该TCI状态可以适用于终端的物理上行共享信道(Physical Uplink Shared Channel，PUSCH)和/或其相应的DMRS，和至少一部分物理上行控制信道(Physical Uplink Control Channel，PUCCH)和/或其相应的DMRS，以及至少一部分探测参考信号(Sounding Reference Signal，SRS)。网络设备如果指示一个联合TCI状态(Joint TCI state)，则该联合TCI状态可以同时适用于上行和下行信道/参考信号。
但是，相关技术只适用于单发送接收点(Single Transmission Reception Point，S-TRP)的情况，没有考虑多发送接收点(Multi Transmission Reception Point，M-TRP)的情况。
对于配置了PDCCH的传输模式为单频网络(Single Frequency Network，SFN)传输模式来说，由于SFN传输方式指来自M-TRP的传输，每个TRP在相同的资源上发送相同的 信号，也即PDCCH在相同的时域资源频域资源和DMRS端口上使用多个TCI状态的准共址QCL假设进行传输。对于关联了两个TCI状态的CORESET的PDCCH接收，当SFN传输方式为SFN A时，终端直接采用多个TCI状态对应的QCL假设；当SFN传输方式为SFN B时，终端不采用最后一个TCI状态对应的QCL假设中的多普勒偏移和多普勒扩展参数。
在单DCI且M-TRP场景下，一个MAC CE和/或DCI信令可以指示多个TCI状态。若指示多个TCI状态时，可以直接采用多个TCI状态监测关联了两个TCI状态的控制资源集的PDCCH。但如果仅指示了一个TCI状态时，关联了两个TCI状态的控制资源集的PDCCH候选资源的监测如何进行，是需要解决的问题。
基于此，本公开实施例提供了一种TCI的确定方法，在终端基于网络设备发送的第一信息确定进行PDCCH传输时所使用的传输方式为SFN传输方式时，基于网络设备发送的第二信息确定第一控制资源集与至少两个TCI状态的关联关系。从而，由于终端和网络设备均能够确定与第一控制资源集关联的至少两个TCI状态，进一步的终端和网络设备能够使用一致的TCI状态进行PDCCH的传输，提高了基于TCI状态的M-TRP传输的信号质量。
值得说明的是，本公开实施例中涉及的TCI状态除另有说明外均是指unified TCI state。
图2是根据一示例性实施例示出的一种TCI的确定方法的流程图，如图2所示，TCI的确定方法用于终端中，包括以下步骤。
