Description

传输配置状态激活方法、装置及存储介质 技术领域
本公开涉及通信技术领域，尤其涉及传输配置状态激活方法、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)进行数据传输。基于波束进行数据传输过程中，网络设备(例如基站)通过信令指示传输配置(Transmission Configuration Indication，TCI)状态，进而指示终端的接收波束或发送波束。
相关技术中，网络设备基于终端上报的测量结果确定多个TCI状态，并通过无线资源控制(Radio Resource Control，RRC)信令将所述多个TCI状态通知给终端。然后针对每个成员载波(Component Carrier，CC)即服务小区/带宽部分(bandwidth part，BWP)，通过媒体接入控制(Medium Access Control，MAC)控制单元(Control Element，CE)在多个TCI状态中指示需要激活的TCI状态。如果终端配置的服务小区/BWP较多时，基站需要发送很多个MAC CE信令去激活各个服务小区/BWP上的TCI状态配置，这样使得信令开销较多。

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TCI状态激活方法可应用于图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。
相关技术中，下行(Downlink，DL)的物理下行控制信道(physical downlink control channel，PDCCH)或物理下行共享信道(physical downlink shared channel，PDSCH)的波束管理(beam management)过程如下：终端与网络设备随机接入完成，并建立好RRC连接之后，终端按照网络设备的测量配置进行测量之后，上报beam的测量结果给网络设备，包括beam的参考信号(Reference Signal，RS)类型和RS索引(index)和层1参考信号接收功率(Layer1-Reference Signal Receiving Power，L1-RSRP)或层1的信号与干扰和噪声比(Signal to Interfere&Noise Ratio，L1-SINR)。网络设备根据终端上报的测量结果确定多个TCI状态。TCI状态包括TCI状态的标识(ID)，以及TCI状态对应的RS类型和RS index。目前TCI状态的数目最多是64个。网络设备通过RRC信令将这64个TCI状态通知给终端，包括TCI状态ID和对应的RS类型和RS index。TCI状态如下表1所示，终端通过TCI状态可确定出接收波束。
表1
Figure PCTCN2019107036-appb-000001
其中，针对PDCCH，网络设备使用MAC CE激活64个TCI状态中的1个TCI状态， 并指示给终端。针对PDSCH，网络设备使用MAC CE激活TCI状态集合(64个TCI状态中的8个TCI状态)，并指示给终端。网络设备再使用下行控制信息(Downlink Control Information，DCI)信令从激活的8个TCI状态中指示其中一个给终端用于终端接收PDSCH。DCI信令中调度的PDSCH的TCI状态，即告知终端接收该PDSCH使用的接收beam要与终端接收该TCI状态中的RS时接收信号最强时使用的接收beam一样。
相关技术中，针对每个CC/BWP使用单独MAC CE激活TCI状态。在多个CC/BWP场景中，针对每个CC/BWP使用单独MAC CE激活TCI状态，信令开销较大。
有鉴于此，本公开提供一种TCI状态激活方法。本公开提供的TCI状态激活方法中，通过一个MAC CE激活同一频段(band)上所有CC/BWP上的PDCCH的TCI状态或所有CC/BWP上的PDSCH的TCI状态集合。
图2是根据一示例性实施例示出的一种TCI状态激活方法的流程图，如图2所示，TCI状态激活方法用于网络设备中，包括以下步骤S11和步骤S12。
在步骤S11中，在终端的同一band上的全部服务小区中选择一个支持发送MAC CE的服务小区。
本公开中对应某个终端，在同一band上配置有多个服务小区(即CC)，每个服务小区上都有一个初始带宽部分(initial BWP)或激活带宽部分(active BWP)。本公开中，网络设备在该同一band上的全部服务小区中选择一个支持发送MAC CE的服务小区，并利用选择的服务小区上的该终端的initial BWP或active BWP上的MAC CE信令激活TCI状态。
本公开中，网络设备选择服务小区时，一方面，网络设备在终端的同一band上的全部服务小区中随机选择一个服务小区，或者在终端的同一band上的全部服务小区中选择指定服务小区。本公开中，网络设备选择的指定服务小区例如为同一band上全部服务小区中载频为最低频的服务小区。或网络设备选择的指定服务小区为同一band上全部服务小区中的主辅小区(PSCell)或主小区(PCell)。或网络设备选择的指定服务小区为非授权频谱上检测到信道空闲的服务小区，即当该频段为非授权频段时，网络设备需要针对该频段上终端的各个服务小区分别进行先听后说的信道检测过程，只有检测到信道空闲的服务小区才能用于发送，所以指定服务小区必须是检测到信道空闲的服务小区。
本公开中，网络设备通过一个服务小区发送的MAC CE信令激活TCI状态。MAC CE激活的TCI状态可以是PDCCH的TCI状态或PDSCH的TCI状态集合。
一种实施方式中，网络设备需将全部TCI状态(例如64个TCI状态)预先通知给终端。例如网络设备基于RRC信令将全部TCI状态预先通知给终端。通过MAC CE信令激活的TCI状态为全部TCI状态中的一个TCI状态或TCI状态集合。
在步骤S12中，利用选择的服务小区发送用于激活TCI状态的MAC CE信令。
本公开中，网络设备在终端的同一band上的全部服务小区中选择一个服务小区发送用于激活全部服务小区TCI状态的MAC CE信令，能够降低信令开销。
图3是根据一示例性实施例示出的一种TCI状态激活方法的流程图，如图3所示，TCI状态激活方法用于终端中，包括以下步骤S21和步骤S22。
在步骤S21中，接收用于激活TCI状态的MAC CE信令。
本公开中对应某个终端，在同一band上配置有多个服务小区即CC，每个服务小区上都有一个初始带宽部分(initial BWP)或激活带宽部分(active BWP)。本公开一方面，终端确定支持MAC CE信令接收和发送的服务小区，并通过确定的服务小区接收MAC CE信令。其中，终端利用确定的服务小区的initial BWP或active BWP来接收MAC CE信令。
其中，终端采用如下方式之一确定用于接收MAC CE信令的服务小区：在终端的同一频段上的全部服务小区中接收所有支持发送MAC CE的服务小区发送的MAC CE。或基于网络设备为终端预配置的服务小区作为接收MAC CE信令的服务小区。或默认将同一频段上全部服务小区中的主辅小区或主小区或载频处在最低频位置的服务小区或检测到信道空闲的非授权频谱小区作为接收MAC CE信令的服务小区。
本公开中，终端接收的MAC CE信令用于激活TCI状态，该TCI状态可以是PDCCH的TCI状态或PDSCH的TCI状态集合。
在步骤S22中，将接收到的MAC CE激活的TCI状态作为同一band上的全部服务小区的TCI状态。
本公开一示例中，终端预先接收网络设备发送的RRC信令，基于RRC信令确定出全部TCI状态。在接收到MAC CE信令后，将MAC CE激活的TCI状态作为同一band上的全部服务小区的PDCCH的TCI状态。或者将MAC CE激活的TCI状态集合作为同一band上的全部服务小区的PDSCH的TCI状态集合。
本公开中，终端接收MAC CE，将接收到的MAC CE激活的TCI状态作为同一band上的全部服务小区的TCI状态，能够减少信令开销。
进一步的，本公开中终端还需确定同一band上的全部服务小区。
一种实施方式中，本公开由网络设备预先发送用于通知终端全部服务小区中每个服务小区的带宽以及载频位置的配置消息，以使终端通过每个服务小区的带宽以及载频位置，确定同一band上的全部服务小区。
图4是根据一示例性实施例示出的一种确定同一band上全部服务小区的方法流程图，如图4所示，确定同一band上全部服务小区的方法用于网络设备中，包括步骤S31。
在步骤S31中，发送配置消息，配置消息用于指示终端全部服务小区中每个服务小区的带宽以及载频位置。
本公开一示例中，网络设备基于系统消息和/或RRC信令发送配置消息。
进一步的，本公开中网络设备发送配置消息后，可执行选择服务小区以及发送MACCE信令的步骤。可以理解的是，本公开中网络设备在每次选择服务小区以及发送MAC CE信令的过程中，不限定是否执行发送配置消息的步骤，可以是每次都执行发送配置消息的步骤，也可以是执行一次发送配置消息的步骤。
本公开中网络设备向终端发送指示终端全部服务小区中每个服务小区的带宽以及载频位置的配置消息，使得终端能够确定出同一band的全部服务小区。
图5是根据一示例性实施例示出的一种确定同一band上全部服务小区的方法流程图，如图5所示，确定同一band上全部服务小区的方法用于终端中，包括步骤S41至步骤S42。
在步骤S41中，接收配置消息，配置消息用于指示终端全部服务小区中每个服务小区的带宽以及载频位置。
配置消息包括系统信息和/或服务小区配置消息，当是主小区的话，其带宽和载频位置是终端接收系统信息获得的，如果是辅小区的话，则是通过主小区发送的辅服务小区配置消息获得的。
本公开一示例中，终端基于系统信息和/或RRC信令接收配置消息。
在步骤S42中，基于每个服务小区的带宽以及载频位置，确定同一band的全部服务小区。
进一步的，本公开中终端接收配置消息并确定同一band的全部服务小区后，可执行接收用于激活TCI状态的MAC CE信令，以及将MAC CE信令激活的TCI状态作为同一band的全部服务小区的TCI状态的步骤。可以理解的是，本公开中终端在每次接收MACCE信令以及将MAC CE信令激活的TCI状态作为同一band的全部服务小区的TCI状态的过程中，不限定是否执行接收配置消息并确定同一band的全部服务小区的步骤，可以 是每次都执行接收配置消息并确定同一band的全部服务小区的步骤，也可以是执行一次接收配置消息并确定同一band的全部服务小区的步骤。
本公开中，终端接收网络设备发送的用于指示终端全部服务小区中每个服务小区的带宽以及载频位置的配置消息，确定出同一band的全部服务小区，进而将同一band的全部服务小区的TCI状态均采用接收到的MAC CE激活的TCI状态，节省信令开销。
进一步的，本公开中，在需要更新激活的TCI状态时，例如，终端信道条件发生变化(根据终端反馈的测量结果确定出新的TCI状态)，终端发生BWP切换、终端发生辅小区(SCell)切换、终端发生PCell或PSCell切换、终端发生PCell或PScell链路失败以及终端发生服务小区波束失败(beam failure)，可由网络设备重新发送激活TCI状态的MAC CE。
本公开中为区分更新前后的不同MAC CE、TCI状态、发送MAC CE的服务小区，将更新前涉及的MAC CE称为第一MAC CE。第一MAC CE激活的TCI状态称为第一TCI状态。为发送第一MAC CE选择的服务小区称为第一服务小区。将进行TCI状态更新时涉及的MAC CE称为第二MAC CE。第二MAC CE激活的TCI状态称为第二TCI状态。为发送第二MAC CE选择的服务小区称为第二服务小区。
图6是根据一示例性实施例示出的一种TCI状态激活方法的流程图，如图6所示，TCI状态激活方法用于网络设备中，包括步骤S51至步骤S54。其中，步骤S51、步骤S52、步骤S53和步骤S31、步骤S32和步骤S33相同，本公开在此不再详述。
在步骤S54中，发送第二MAC CE信令，所述第二MAC CE信令用于激活第二TCI状态。
本公开中，网络设备在发送第二MAC CE信令之前，需确认需要更新TCI状态，即需要激活第二TCI状态。其中，需要激活第二TCI状态可以理解为是发生如下事件之一或组合：终端信道条件发生变化(根据终端反馈的测量结果确定)，终端发生BWP切换、终端发生辅小区(SCell)切换、终端发生PCell或PSCell切换、终端发生PCell或PSCell链路失败以及终端发生服务小区波束失败(beam failure)。
本公开中，在终端需要进行TCI状态更新时，网络设备重新发送新的MAC CE信令(第二MAC CE信令)，以激活新的TCI状态，便于终端进行TCI状态更新。
本公开中，网络设备向终端发送第二MAC CE信令后，终端在接收到MAC CE信令之后，则可将第一TCI状态更新为第二MAC CE信令激活的第二TCI状态。
然而，终端在发生BWP切换、辅小区(SCell)切换、PCell或PSCell切换、PCell或PSCell链路失败以及服务小区波束失败(beam failure)时，终端如何进行TCI状态的处理，是需要解决的问题。本公开以下将示例性的针对此种情况进行说明。
情形一：发生BWP切换
图7是根据一示例性实施例示出的一种TCI状态激活方法的流程图。如图7所示，TCI状态激活方法用于终端中，包括步骤S61至步骤S69。
在步骤S61中，接收配置消息，配置消息用于指示终端全部服务小区中每个服务小区的带宽以及载频位置。
在步骤S62中，基于每个服务小区的带宽以及载频位置，确定同一band的全部服务小区。
在步骤S63中，在全部服务小区中确定一个第一服务小区，利用第一服务小区的initial BWP或active BWP来接收用于激活第一TCI状态的第一MAC CE信令。
在步骤S64中，将第一MAC CE信令激活的第一TCI状态作为同一band的全部服务小区的TCI状态。
在步骤S65中，确定发生BWP切换，确定是否接收到网络设备发送的用于激活第二TCI状态的第二MAC CE信令。
本公开中，若在同一band的全部服务小区中任意服务小区上发生BWP切换，则确定发生BWP切换。本公开中，终端发生BWP切换可以理解为是终端收到了网络设备新调度的BWP，并由原BWP切换到新调度的BWP上。
本公开中，第一MAC CE信令激活的第一TCI状态为PDCCH的TCI状态或者PDSCH的TCI状态集合。相应的，第二MAC CE信令激活的第二TCI状态为PDCCH的TCI状态或者PDSCH的TCI状态集合。
本公开中终端未接收到网络设备发送的用于激活第二TCI状态的第二MAC CE信令，且第一MAC CE信令激活的第一TCI状态为PDCCH的TCI状态时，执行步骤S66。本公开中终端未接收到网络设备发送的用于激活第二TCI状态的第二MAC CE信令，且第一MAC CE信令激活的第一TCI状态为PDSCH的TCI状态集合时，执行步骤S67和步骤S68。
在步骤S66中，在切换后的BWP上，利用第一TCI状态接收在切换后的BWP上所发送的PDCCH。
在步骤S67中，接收DCI信令。
本公开中，接收的DCI信令用于指示第一TCI状态中的一个TCI状态，而该DCI信令是在该服务小区上切换前的BWP上接收，或是在该服务小区上切换后的BWP上接收，或是在其它服务小区上的BWP上接收(比如跨载波调度的情况下)。第一TCI状态为PDSCH的TCI状态集合时，接收的DCI信令用于指示TCI状态集合中的一个TCI状态。
在步骤S68中，利用DCI指示的TCI状态接收在切换后的BWP上所发送的PDSCH。
本公开中在终端接收到网络设备发送的用于激活第二TCI状态的第二MAC CE信令时，执行步骤S69。
在步骤S69中，将第一MAC CE信令激活的第一TCI状态更新为第二MAC CE信令激活的第二TCI状态。
本公开中，在终端的任意服务小区发生BWP切换时，网络设备调度新的BWP上的RB给终端发送PDSCH，那么如果在此期间没有新的MAC信令来激活新的TCI状态(或TCI状态集合)。对于PDCCH，终端在新的BWP上基于之前MAC信令激活的BWP上的PDCCH的TCI状态来接收新的BWP上发送的PDCCH。而对于PDSCH的TCI状态集合，也是使用之前MAC信令激活的BWP上的PDSCH的TCI状态集合。而用于指示从MAC信令激活的TCI状态集合中的一个TCI状态来接收PDSCH的DCI信令：可能由切换前的BWP发送，也可能在终端切换到新的BWP后由新的BWP发送，或者当为跨载波调度情况下由其它服务小区上的BWP发送。终端结合用于调度新的BWP上的PDSCH的DCI信令和原MAC信令激活的TCI状态集合来确定用于接收新的BWP上的PDSCH的TCI状态。直到有新的MAC信令重新激活新的PDCCH的TCI状态或新的PDSCH的TCI状态集合为止。
情形二：发生SCell切换
图8是根据一示例性实施例示出的一种TCI状态激活方法的流程图。如图8所示，TCI状态激活方法用于终端中，包括步骤S71至步骤S76。
在步骤S71中，接收配置消息，配置消息用于指示终端全部服务小区中每个服务小区的带宽以及载频位置。
在步骤S72中，基于每个服务小区的带宽以及载频位置，确定同一band的全部服务小区。
在步骤S73中，在全部服务小区中确定一个第一服务小区，利用第一服务小区的initial BWP或active BWP来接收用于激活第一TCI状态的第一MAC CE信令。
在步骤S74中，将第一MAC CE信令激活的第一TCI状态作为同一band的全部服务小区的TCI状态。
在步骤S75中，确定发生SCell切换。
本公开中，终端在同一band的全部SCell中任意一SCell发生切换，确定发生SCell切换。
在步骤S76中，在切换后的SCell上复用切换前的SCell上的第一TCI状态。
本公开中，第一MAC CE信令激活的第一TCI状态为PDCCH的TCI状态或者PDSCH的TCI状态集合。相应的，第二MAC CE信令激活的第二TCI状态为PDCCH的TCI状态或者PDSCH的TCI状态集合。
本公开中，当同一band下的其中一个SCell发生SCell切换时，切换后的SCell也需要复用原SCell上第一MAC CE信令激活的PDCCH的TCI状态和PDSCH的TCI状态集合。
情形三：发生PSCell或PCell切换
图9是根据一示例性实施例示出的一种TCI状态激活方法的流程图。如图9所示，TCI状态激活方法用于终端中，包括步骤S81至步骤S86。
在步骤S81中，接收配置消息，配置消息用于指示终端全部服务小区中每个服务小区的带宽以及载频位置。
在步骤S82中，基于每个服务小区的带宽以及载频位置，确定同一band的全部服务小区。
在步骤S83中，在全部服务小区中确定一个第一服务小区，利用第一服务小区的initial BWP或active BWP来接收用于激活第一TCI状态的第一MAC CE信令。
在步骤S84中，将第一MAC CE信令激活的第一TCI状态作为同一band的全部服务小区的TCI状态。
在步骤S85中，确定发生PSCell或PCell切换。
在步骤S86中，接收第二MAC CE信令，并将全部服务小区的第一TCI状态更新为第二MAC CE信令激活的第二TCI状态。
本公开中，第一MAC CE信令激活的第一TCI状态为PDCCH的TCI状态或者PDSCH的TCI状态集合。相应的，第二MAC CE信令激活的第二TCI状态为PDCCH的TCI状 态或者PDSCH的TCI状态集合。
本公开中，当同一band下的PSCell或PCell发生切换时，需要重新对TCI状态进行配置，所以需要对该band上所有CC/BWP的TCI状态进行更新，即使用新的RRC信令、MAC CE信令等进行TCI状态配置。
情形四：发生beam failure
图10是根据一示例性实施例示出的一种TCI状态激活方法的流程图。如图10所示，TCI状态激活方法用于终端中，包括步骤S91至步骤S96。
在步骤S91中，接收配置消息，配置消息用于指示终端全部服务小区中每个服务小区的带宽以及载频位置。
在步骤S92中，基于每个服务小区的带宽以及载频位置，确定同一band的全部服务小区。
在步骤S93中，在全部服务小区中确定一个第一服务小区，利用第一服务小区的initial BWP或active BWP来接收用于激活第一TCI状态的第一MAC CE信令。
在步骤S94中，将第一MAC CE信令激活的第一TCI状态作为同一band的全部服务小区的TCI状态。
在步骤S95中，确定存在发生beam failure的服务小区，重新确定发生beam failure的服务小区的TCI状态。
本公开中，当同一band下的其中一个服务小区发生beam failure时，相当于该SCell上的PDCCH的TCI状态需要更新了，那么终端重新确定接收该SCell上的PDCCH的TCI状态或PDSCH的TCI状态集合。
其中，PDCCH的TCI状态可以是终端通过测量自行确定。比如一方面，终端检测用于新的beam发现的SSB发现RSRP和/或SINR较高，则在该SSB对应的物理随机接入信道(Physical Random Access Channel，PRACH)发送对应的随机接入前导码，则网络设备就能够确定使用该SSB相同的波束给该终端发送PDCCH或PDSCH比较合适。另一方面，也可以是终端通过测量然后将测量结果上报给网络设备，或将选择出的一个新的beam ID上报给网络设备，然后网络设备使用终端上报的一个或多个中的一个或多个来给终端发送PDCCH或PDSCH。
在步骤S96中，确定是否接收到网络设备发送的用于激活第二TCI状态的第二MACCE信令。
在终端未接收到第二MAC CE激活的第二TCI状态时，执行步骤S97。在终端接收到第二MAC CE激活的第二TCI状态时，执行步骤S98。
在步骤S97中，将全部服务小区中除发生beam failure的服务小区以外的其它服务小区的TCI状态更新为发生beam failure的服务小区重新确定的TCI状态，或者将全部服务小区中除发生beam failure的服务小区以外的其它服务小区的TCI状态保持不变。
在步骤S98中，将第一MAC CE信令激活的第一TCI状态更新为第二MAC CE信令激活的第二TCI状态。
本公开中，同一band下的其中一个服务小区发生beam failure时，终端重新确定接收该SCell上的PDCCH的TCI状态或PDSCH的TCI状态集合。其中PDCCH的TCI状态可以是终端通过测量确定。在这个过程中，由于不是MAC CE信令给该发生beam failure的SCell重新激活新的TCI状态，故该band下除发生beam failure以外的其它服务小区可以有两种选择：一种继续使用之前MAC信令激活的TCI状态或TCI状态集合。另一种是使用与beam failure的服务小区相同的TCI状态。待基站使用新的MAC信令给发生beam failure的服务小区激活新的TCI状态时，则同一band下所有的服务小区即CC/BWP都使用新的MAC激活的TCI状态。
情形五：发生链路失败
终端发生链路失败表明终端的PCell或PSCell的PDCCH的TCI状态需要更新。这种情况下，在没有接收到第二MAC CE激活的第二TCI状态之前，除PCell或PSCell之外的服务小区的TCI状态同样可以有两种方法：一是继续使用第一MAC CE激活的第一TCI状态；二是使用与重新确定的PCell或PSCell中的TCI状态相同的TCI状态。
图11是根据一示例性实施例示出的一种TCI状态激活方法的流程图。如图11所示，TCI状态激活方法用于终端与网络设备交互过程中，包括步骤S101至步骤S109。
在步骤S101中，网络设备在终端的同一band上的全部服务小区中选择一个第一服务小区，选择的第一服务小区支持发送MAC CE信令。
在步骤S102中，网络设备利用选择的一个第一服务小区发送第一MAC CE信令，第一MAC CE信令用于激活第一TCI状态。终端接收第一MAC CE。
在步骤S103中，网络设备发送配置消息，配置消息用于指示终端全部服务小区中每个服务小区的带宽以及载频位置。终端接收网络设备发送的配置消息。
在步骤S104中，终端根据配置消息中每个服务小区的带宽以及载频位置，确定同一 band的全部服务小区。
可以理解的是，本公开中步骤S103和步骤S104为可选步骤，步骤S103和S104可以在步骤S101之前发生。例如，终端采用预定义方式确定同一band的全部服务小区时，无需执行步骤S103和步骤S104。
在步骤S105中，终端将第一TCI状态作为同一band上的全部服务小区的TCI状态。
本公开中，终端将第一TCI状态作为同一band上的全部服务小区的TCI状态之后，根据实际应用场景可包括如下步骤。
在步骤S106a中，若在任意服务小区上确定发生BWP切换，且未接收到第二MAC CE信令，则在切换后的BWP上，利用第一TCI状态接收在切换后的BWP上所发送的物理下行控制信道。若接收到第二MAC CE信令，将第一TCI状态更新为第二TCI状态。
在步骤S106b中，若在任意服务小区上确定发生BWP切换，且未接收到第二MAC CE信令，则接收DCI，DCI用于指示第一TCI状态中的一个TCI状态。利用DCI指示的TCI状态接收在切换后的BWP上所发送的物理下行共享信道。若接收到第二MAC CE信令，将第一TCI状态更新为第二TCI状态。
在步骤S107中，若确定发生SCell切换，则在切换后的SCell上复用切换前的SCell上的第一TCI状态。
在步骤S108中，若确定发生PCell或PSCell切换，则接收第二MAC CE信令，并将全部服务小区的第一TCI状态更新为第二MAC CE信令激活的第二TCI状态。
在步骤S109中，若确定存在发生beam failure的服务小区，则重新确定发生beam failure的服务小区的TCI状态。若未接收到第二MAC CE信令激活的第二TCI状态，将全部服务小区中除发生beam failure的服务小区以外的其它服务小区的TCI状态更新为发生beam failure的服务小区重新确定的TCI状态。或者将全部服务小区中除发生beam failure的服务小区以外的其它服务小区的TCI状态保持不变。若接收到第二MAC CE信令，将第一TCI状态更新为第二TCI状态。
可以理解的是，本公开中用于终端与网络设备交互过程中的TCI状态激活方法中，对于终端和网络设备分别具有本公开以上实施例中涉及的针对终端和网络设备实施TCI状态激活过程中的方法。对于本公开中终端与网络设备交互过程中的TCI状态激活方法描述不够详尽的地方，可参阅相关实施例的描述，在此不再赘述。
