具体实施方式
在下文中将结合附图对本发明的示范性实施例进行描述。为了清楚和简明起见，在说明书中并未描述实际实施方式的所有特征。然而，应该了解，在开发任何这种实际实施例的过程中必须做出很多特定于实施方式的决定，以便实现开发人员的具体目标，例如，符合与系统及业务相关的那些限制条件，并且这些限制条件可能会随着实施方式的不同而有所改变。此外，还应该了解，虽然开发工作有可能是非常复杂和费时的，但对得益于本公开内容的本领域技术人员来说，这种开发工作仅仅是例行的任务。
在此，还需要说明的一点是，为了避免因不必要的细节而模糊了本发明，在附图中仅仅示出了与根据本发明的方案密切相关的设备结构和/或处理步骤，而省略了与本发明关系不大的其他细节。
<第一实施例>
如前所述，TCI状态用于指示服务小区的下行波束，每个TCI状态对应于一个下行参考信号(CSI-RS或者SSB)，即对应于一个下行发射波束的方向。对于TCI状态的配置是通过无线资源控制(Radio Resource Control，RRC)参数配置TCI-state information element实现的，如图1所示。其中，tci-StateId表示TCI状态的标识(ID)，ServCellIndex表示UE的服务小区的ID，NZP-CSI-RS-ResourceId表示该TCI状态对应的CSI-RS资源的ID，SSB-Index表示该TCI状态对应的SSB的ID。
可以看出，该TCI状态信息元素中索引的参考信号均为下行参考信号，因此不能用于指示上行波束。为了解决这一问题，本实施例提出了一种统一(unified)TCI状态，其能够用于上行波束和下行波束两者。
图2示出了根据本申请的一个实施例的用于无线通信的电子设备 100的功能模块框图，如图2所示，电子设备100包括：获取单元101，被配置为从基站获取统一TCI状态的配置信息，其中，统一TCI状态用于指示下行波束和上行波束两者；以及执行单元102，被配置为基于该配置信息来执行波束管理相关的操作。
其中，获取单元101和执行单元102可以由一个或多个处理电路实现，该处理电路例如可以实现为芯片、处理器。并且，应该理解，图2中所示的电子设备中的各个功能单元仅是根据其所实现的具体功能而划分的逻辑模块，而不是用于限制具体的实现方式。
电子设备100例如可以设置在UE侧或者可通信地连接到UE。这里，还应指出，电子设备100可以以芯片级来实现，或者也可以以设备级来实现。例如，电子设备100可以工作为UE本身，并且还可以包括诸如存储器、收发器(图中未示出)等外部设备。存储器可以用于存储用户设备实现各种功能需要执行的程序和相关数据信息。收发器可以包括一个或多个通信接口以支持与不同设备(例如，基站、其他用户设备等等)间的通信，这里不具体限制收发器的实现形式。
在一个示例中，统一TCI状态的配置信息包括单独的上行TCI状态的配置信息和下行TCI状态的配置信息。例如，下行TCI状态可以利用现有架构中的TCI状态(以下也称为下行TCI状态)，并在此基础上另外定义上行TCI状态来指示上行波束的方向。在这种情况下，可以在PUSCH-Config中定义上行TCI状态的池。对于上行TCI状态的配置可以与图1类似，例如将tci-StateId替换为ul-tci-StateId，索引的参考信号替换为上行参考信号比如探测参考信号(Sounding Reference Signal，SRS)。
基站可以通过媒体接入控制控制元素(Media Access Control-Control Element，MAC CE)来激活或去激活下行波束，例如，可以将待激活或待去激活的下行波束对应的下行TCI状态的标识(ID)包括在MAC CE中发送给UE。类似地，基站也可以通过MAC CE来激活或去激活上行波束，例如，可以将待激活或待去激活的上行波束对应的上行TCI状态的ID包括在MAC CE中发送给UE。
执行单元102基于获取的配置信息执行波束管理相关的操作，例如用于移动性管理的波束测量、上报等。此外，执行单元102在接收到MAC  CE信令之后还执行波束的激活、去激活等。进一步地，当MAC CE激活的是数据波束时，执行单元102还被配置为基于基站发送的下行控制信息(Downlink Control Information，DCI)来动态地确定激活的数据波束中的一个作为物理下行共享信道(Physical Downlink Shared Channel,PDSCH)或物理上行共享信道(Physical Uplink Shared Channel,PUSCH)的发射波束。
此外，为了减少信令开销，可以设计使用单一的MAC CE来分别为上行和下行激活或去激活对应的上行TCI状态和下行TCI状态。例如，上行TCI状态和下行TCI状态至少部分地共用ID，获取单元101被配置为从基站获取包含目标TCI状态的标识的MAC CE，并在所获取的目标TCI状态的ID为共用ID的情况下，同时激活或去激活该共用ID对应的上行TCI状态和下行TCI状态。其中，目标TCI状态的ID为待激活或待去激活的TCI状态的ID。
图3示出了上行TCI状态和下行TCI状态部分地共用ID的情况的一个示例。在图3的示例中，假设RRC信令可以配置的上行TCI状态和下行TCI状态的最大数目均为128，随后MAC CE信令包括8个被激活的TCI状态的ID，图3中所示的由PUSCH-Config定义的上行TCI状态池和由PDSCH-Config定义的下行TCI状态池中有8个TCI状态的ID彼此相同。因此，在MAC CE信令中包括这8个ID的情况下，可以同时指示对应的8个下行TCI状态和8个上行TCI状态，从而由一条MAC CE信令同时实现上行波束和下行波束的激活或去激活。
在另一个示例中，可以对现有的TCI状态进行修改以获得统一TCI状态。例如，统一TCI状态的配置信息包括对上行参考信号和下行参考信号中的一个参考信号的索引。上行参考信号包括SRS，下行参考信号包括CSI-RS和SSB。其中，CSI-RS、SSB和SRS的准共址(Quasi-Co-Location，QCL)类型均为QCL-TypeD，即是关于空间接收滤波器的。
图4示出了统一TCI状态信息元素的示例。与图1相比，图4的示例中增加了对于SRS的索引。换言之，可以通过对SRS的索引来直接配置上行波束的TCI状态。
获取单元101还被配置为通过MAC CE或DCI来接收对于目标TCI 状态的指示。这里的目标TCI状态指的是待激活或者待去激活或者待指示的TCI状态，这里的TCI状态为统一TCI状态。例如，MAC CE或DCI中可以包括目标TCI状态的标识，比如图4中所示的U-tci-StateId。
其中，基站可以通过MAC CE信令来激活或去激活所配置的多个上行波束或下行波束中的一个或多个。当通过MAC CE激活控制波束比如PDCCH和PUCCH时，执行单元102被配置为激活PDCCH和PUCCH所在的控制资源集合(Control Resource Set,CORESET)上的相应的波束。当通过MAC CE激活数据波束时，执行单元102还被配置为基于基站发送的DCI来动态地确定激活的数据波束中的一个作为PDSCH或PUSCH的发射波束，此时，DCI指示的TCI状态为目标TCI状态。
在统一TCI状态包括对上行参考信号(比如SRS)的索引的情况下，执行单元102被配置为确定使用发射目标TCI状态所对应的上行参考信号的发射波束来进行上行信道比如PUCCH或PUSCH的发射，并且使用该发射波束来进行下行信道比如PDCCH或PDSCH的接收。
在统一TCI状态包括对下行参考信号(比如CSI-RS或SSB)的索引的情况下，执行单元103被配置为确定使用先前用于对目标TCI状态所对应的下行参考信号进行测量的接收波束来进行下行信道的接收，并且使用该接收波束来进行上行信道的发射。
此外，UE可以配备有多个天线面板，可以采用作为上行波束管理所使用的SRS资源集合的ID来作为各个天线面板的ID。在上行波束扫描时，每一个天线面板会被分配一个专属的SRS资源集合，并使用每个资源集合内的SRS资源进行上行波束扫描。
UE可以通过UE能力的信令告知网络侧比如基站它配备了多个天线面板，网络侧可以通过RRC信令配置或者MAC CE来激活该UE使用特定的某个天线面板或多个天线面板的组合来进行下行参考信号(CSI-RS或SSB)的测量，例如测量该天线面板或天线面板组合接收到的L1-RSRP(层1参考信号接收功率)或L1-SINR(层1信号干扰噪声比)。图5示出了一个特定天线面板对下行参考信号进行测量的示例。
换言之，执行单元102可以使用指定的一个或多个天线面板进行下行参考信号的测量。作为一种方式，获取单元101可以从基站获取所指定的一个或多个天线面板的信息，例如可以获取相应的SRS资源集合 ID。作为另一种方式，执行单元102可以自行确定一个或多个天线面板，并将这一个或多个天线面板的ID报告给基站，以便于后续的波束指示。
在这种情况下，如果统一TCI状态包括对下行参考信号(比如CSI-RS或SSB)的索引，则执行单元103确定要使用之前对该下行参考信号进行测量的天线面板和该天线面板上的波束来进行下行信道的接收。换言之，接收波束为所指定的一个或多个天线面板上的波束。此外，在下行参考信号的接收波束与SRS的发射波束对应的情况下，还使用该接收波束来进行上行信道的发射。
这样，本实施例的统一TCI状态能够支持UE的指定天线面板和波束的下行接收，并且统一TCI状态与特定的天线面板或天线面板的组合相关联。
类似地，如果统一TCI状态包括对上行参考信号(SRS)的索引，执行单元103也可以基于该SRS所在的SRS资源集合的ID来确定要进行上行信道的发射的天线面板和天线面板上的波束，并且还可以使用该发射波束来进行下行信道的接收。其中，该SRS所在的SRS资源集合的目的应该是用于Codebook或non-codebook传输的。
另一方面，如图6所示，电子设备100还包括发送单元103，被配置为在上行传输发生故障和/或辐射超过最大允许暴露(Maximum Permissible Exposure，MPE)的情况下，向基站上报目标TCI状态的ID，以使得基站基于该ID确定对应的天线面板。例如，发送单元103可以通过MAC CE或者RRC信令来进行上报。
由于UE的天线面板可能对人体造成过量的辐射或者发生故障，因此需要将存在问题的天线面板的信息报告给基站，这样基站可以暂停该天线面板的波束测量、上报等动作。即，基站可以指示UE不使用该天线面板进行上行传输。
发送单元103可以直接上报存在问题的天线面板的ID。在本实施例中，由于目标TCI状态与特定的一个或多个天线面板相关联，因此发送单元103也可以通过上报目标TCI状态的ID来向基站报告出问题的天线面板。
为了便于理解，图7示出了根据本实施例的UE与gNB之间的信息流程的一个示例。其中，gNB通过RRC信令向UE发送统一TCI状态 的配置信息，其中，统一TCI状态用于指示下行波束和上行波束两者。随后，gNB通过MAC CE信令激活一个或多个统一TCI状态，即，激活一个或多个上行波束以及一个或多个下行波束。对于数据信道，gNB还通过DCI来指示激活的多个数据波束中的一个用于PDSCH或PUSCH的发射。此外，在上行传输发生故障和/或MPE问题时，UE还通过MAC CE或RRC信令进行上报。
综上所述，根据本实施例的电子设备100通过应用指示下行波束和上行波束两者的统一TCI状态，使得能够利用统一TCI状态同时进行下行波束和上行波束管理，减小了信令开销。
<第二实施例>
图8示出了根据本申请的另一个实施例的电子设备200的功能模块框图，如图8所示，电子设备200包括：发送单元201，被配置为向UE发送统一TCI状态的配置信息，其中，统一TCI状态用于指示下行波束和上行波束两者；以及执行单元202，被配置为基于配置信息来执行波束管理相关的操作。
其中，发送单元201和执行单元202可以由一个或多个处理电路实现，该处理电路例如可以实现为芯片、处理器。并且，应该理解，图8中所示的电子设备中的各个功能单元仅是根据其所实现的具体功能而划分的逻辑模块，而不是用于限制具体的实现方式。
电子设备200例如可以设置在基站侧或者可通信地连接到基站。本申请中所述的基站也可以是收发点(Transmit Receive Point，TRP)或者接入点(Access Point,AP)。这里，还应指出，电子设备200可以以芯片级来实现，或者也可以以设备级来实现。例如，电子设备200可以工作为基站本身，并且还可以包括诸如存储器、收发器(未示出)等外部设备。存储器可以用于存储基站实现各种功能需要执行的程序和相关数据信息。收发器可以包括一个或多个通信接口以支持与不同设备(例如，UE、其他基站等等)间的通信，这里不具体限制收发器的实现形式。
在一个示例中，统一TCI状态的配置信息包括单独的上行TCI状态的配置信息和下行TCI状态的配置信息。例如，下行TCI状态可以利用现有架构中的TCI状态(以下也称为下行TCI状态)，并在此基础上另 外定义上行TCI状态来指示上行波束的方向。在这种情况下，可以在PUSCH-Config中定义上行TCI状态的池。对于上行TCI状态的配置可以与图1类似，例如将tci-StateId替换为ul-tci-StateId，索引的参考信号替换为上行参考信号比如探测参考信号(Sounding Reference Signal，SRS)。
如前所述，基站可以通过MAC CE来激活或去激活下行波束，例如，发送单元201还可以将待激活或待去激活的下行波束对应的下行TCI状态的ID包括在MAC CE中发送给UE。类似地，基站也可以通过MAC CE来激活或去激活上行波束，例如，发送单元201可以将待激活或待去激活的上行波束对应的上行TCI状态的ID包括在MAC CE中发送给UE。
执行单元202基于上述配置信息执行波束管理相关的操作，例如上下行波束的激活、指示等。进一步地，当MAC CE要激活的是数据波束时，执行单元202还被配置为通过DCI来动态地确定激活的数据波束中的一个作为PDSCH或PUSCH的发射波束。该DCI由发送单元201发送至UE。
此外，为了减少信令开销，可以设计使用单一的MAC CE来分别为上行和下行激活或去激活对应的上行TCI状态和下行TCI状态。例如，上行TCI状态和下行TCI状态至少部分地共用ID，发送单元201被配置为向UE发送包含作为共用ID的目标TCI状态的标识的MAC CE，以同时激活或去激活该共用ID对应的上行TCI状态和下行TCI状态。其中，目标TCI状态的ID为待激活或待去激活的TCI状态的ID。上行TCI状态和下行TCI状态部分地共用ID的情况的示例可返回参照图3，在此不再重复。
在另一个示例中，可以对现有的TCI状态进行修改以获得统一TCI状态。例如，统一TCI状态的配置信息包括对上行参考信号和下行参考信号中的一个参考信号的索引。上行参考信号包括SRS，下行参考信号包括CSI-RS和SSB。其中，CSI-RS、SSB和SRS的QCL类型均为QCL-TypeD，即是关于空间接收滤波器的。统一TCI状态信息元素的示例可返回参照图4，在此不再重复。
发送单元201还被配置为通过MAC CE或DCI来向UE发送对于目 标TCI状态的指示。这里的目标TCI状态指的是待激活或者待去激活或者待指示的TCI状态，这里的TCI状态为统一TCI状态。例如，MAC CE或DCI中可以包括目标TCI状态的标识，比如图4中所示的U-tci-StateId。
其中，基站可以通过MAC CE信令来激活或去激活所配置的多个上行波束或下行波束中的一个或多个。当通过MAC CE激活控制波束比如PDCCH和PUCCH时，执行单元202被配置为激活PDCCH和PUCCH所在的CORESET上的相应的波束。当通过MAC CE激活数据波束时，执行单元202还被配置为通过DCI来动态地确定激活的数据波束中的一个作为PDSCH或PUSCH的发射波束，此时，DCI指示的TCI状态为目标TCI状态。
如前所述，在统一TCI状态包括对上行参考信号(比如SRS)的索引的情况下，UE可以确定使用发射目标TCI状态所对应的上行参考信号的发射波束来进行上行信道比如PUCCH或PUSCH的发射，并且使用该发射波束来进行下行信道比如PDCCH或PDSCH的接收。
在统一TCI状态包括对下行参考信号(比如CSI-RS或SSB)的索引的情况下，UE可以确定使用先前用于对目标TCI状态所对应的下行参考信号进行测量的接收波束来进行下行信道的接收，并且使用该接收波束来进行上行信道的发射。
此外，UE可以配备有多个天线面板，可以采用作为上行波束管理所使用的SRS资源集合的ID来作为各个天线面板的ID。在上行波束扫描时，每一个天线面板会被分配一个专属的SRS资源集合，并使用每个资源集合内的SRS资源进行上行波束扫描。
UE可以通过UE能力的信令告知网络侧比如基站它配备了多个天线面板，基站可以通过RRC信令配置或者MAC CE来激活该UE使用特定的某个天线面板或多个天线面板的组合来进行下行参考信号(CSI-RS或SSB)的测量，例如测量该天线面板或天线面板组合接收到的L1-RSRP(层1参考信号接收功率)或L1-SINR(层1信号干扰噪声比)。
换言之，UE可以使用指定的一个或多个天线面板进行下行参考信号的测量。作为一种方式，UE可以从基站获取所指定的一个或多个天线面板的信息，例如可以获取相应的SRS资源集合ID。作为另一种方式， UE可以自行确定一个或多个天线面板，并将这一个或多个天线面板的ID报告给基站，以便于后续的波束指示。
在这种情况下，如果统一TCI状态包括对下行参考信号(比如CSI-RS或SSB)的索引，则UE确定要使用之前对该下行参考信号进行测量的天线面板和该天线面板上的波束来进行下行信道的接收。换言之，接收波束为所指定的一个或多个天线面板上的波束。此外，在下行参考信号的接收波束与SRS的发射波束对应的情况下，还使用该接收波束来进行上行信道的发射。
这样，本实施例的统一TCI状态能够支持UE的指定天线面板和波束的下行接收，并且统一TCI状态与特定的天线面板或天线面板的组合相关联。
类似地，如果统一TCI状态包括对上行参考信号(SRS)的索引，则UE也可以基于该SRS所在的SRS资源集合的ID来确定要进行上行信道的发射的天线面板和天线面板上的波束，并且还可以使用该发射波束来进行下行信道的接收。其中，该SRS所在的SRS资源集合的目的应该是用于Codebook或non-codebook传输的。
另一方面，如图9所示，电子设备200还包括接收单元203，被配置为从UE接收统一TCI状态的ID，以确定与该统一TCI状态对应的天线面板的上行传输发生故障和/或辐射超过MPE。例如，接收单元203可以通过MAC CE或者RRC信令来进行接收。
如前所述，由于UE的天线面板可能对人体造成过量的辐射或者发生故障，因此在接收到这样的报告之后，基站可以暂停该天线面板的波束测量、上报等动作。例如，发送单元201可以指示UE不使用该天线面板进行上行传输。
UE可以直接上报存在问题的天线面板的ID。在本实施例中，由于统一TCI状态与特定的一个或多个天线面板相关联，因此UE也可以通过上报统一TCI状态的ID来向基站报告出问题的天线面板。
根据本实施例的基站与UE之间的信息流程例如可以参照图7所示，在此不再重复。
综上所述，根据本实施例的电子设备200通过应用指示下行波束和 上行波束两者的统一TCI状态，使得能够利用统一TCI状态同时进行下行波束和上行波束管理，减小了信令开销。
<第三实施例>
在上文的实施方式中描述用于无线通信的电子设备的过程中，显然还公开了一些处理或方法。下文中，在不重复上文中已经讨论的一些细节的情况下给出这些方法的概要，但是应当注意，虽然这些方法在描述用于无线通信的电子设备的过程中公开，但是这些方法不一定采用所描述的那些部件或不一定由那些部件执行。例如，用于无线通信的电子设备的实施方式可以部分地或完全地使用硬件和/或固件来实现，而下面讨论的用于无线通信的方法可以完全由计算机可执行的程序来实现，尽管这些方法也可以采用用于无线通信的电子设备的硬件和/或固件。
图10示出了根据本申请的一个实施例的用于无线通信的方法的流程图，该方法包括：从基站获取统一TCI状态的配置信息(S11)，其中，统一TCI状态用于指示下行波束和上行波束两者；以及基于该配置信息来执行波束管理相关的操作(S12)。该方法例如可以在UE侧执行。
在一个示例中，统一TCI状态的配置信息包括单独的上行TCI状态的配置信息和下行TCI状态的配置信息。
例如，上行TCI状态与下行TCI状态至少部分地共用标识。虽然图中未示出，上述方法还包括从基站获取包含目标TCI状态的标识的媒体接入控制控制元素，并在所获取的目标TCI状态的标识为共用标识的情况下，同时激活或去激活该共用标识对应的上行TCI状态和下行TCI状态。
在另一个示例中，统一TCI状态的配置信息包括对上行参考信号和下行参考信号中的一个参考信号的索引。其中，上行参考信号包括SRS，下行参考信号包括CSI-RS和SSB。
虽然图中未示出，上述方法还可以包括通过MAC CE或DCI来接收对于目标TCI状态的指示。
