Description

电子设备、无线通信方法和计算机可读存储介质
本申请要求于2020年8月19日提交中国专利局、申请号为202010836807.4、发明名称为“电子设备、无线通信方法和计算机可读存储介质”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本公开的实施例总体上涉及无线通信领域，具体地涉及电子设备、无线通信方法和计算机可读存储介质。更具体地，本公开涉及一种作为无线通信***中的网络侧设备的电子设备、一种作为无线通信***中的用户设备的电子设备、一种由无线通信***中的网络侧设备执行的无线通信方法、一种由无线通信***中的用户设备执行的无线通信方法以及一种计算机可读存储介质。
背景技术
在包括NTN(Non-terrestrial network，非地面网络)的无线通信***中，卫星设备可以产生多个波束。进一步，一个PCI(Physical Cell ID，物理小区ID)可以对应于多个波束。这样一来，在波束切换时无需进行小区切换，从而避免频繁的同步和RRC重连等操作。
此外，波束与频域资源可以具有绑定关系，这里的频域资源包括但不限于BWP(Bandwidth Part，带宽部分)。也就是说，特定的波束只能在具有绑定关系的BWP上进行传输。
因此，在包括NTN的无线通信***中，在频域资源与波束绑定的情况下，网络侧设备如何向用户设备指示用于上行传输或者下行传输的频域资源和波束是需要解决的技术问题。此外，如果只为用户设备激活了一个下行BWP，由于BWP与波束具有绑定关系，那么下行控制信息和下行数据信息需要采用相同的波束。类似地，如果只为用户设备激活了一个上行BWP，由于BWP与波束具有绑定关系，那么上行控制信息和上行数据信息需要采用相同的波束。因此，在这种情况下，如何保证上行控制信息和上行数据信息的波束一致、如何保证下行控制信息和下行数据信息的波束一致也是需要解决的技术问题。
因此，有必要提出一种技术方案，以解决以上技术问题中的至少一个。
发明内容
这个部分提供了本公开的一般概要，而不是其全部范围或其全部特征的全面披露。
本公开的目的在于提供一种电子设备、无线通信方法和计算机可读存储介质，以在波束和频域资源绑定的情况下改进对波束和频域资源的指示过程。
根据本公开的一方面，提供了一种电子设备，包括处理电路，被配置为：生成第一下行控制信令，其中，所述第一下行控制信令包括第一频域指示信息和第一波束指示信息，并且所述第一频域指示信息所指示的频域资源和与所述第一波束指示信息所指示的波束相对应的频域资源相同；以及向用户设备发送所述第一下行控制信令。
根据本公开的另一方面，提供了一种电子设备，包括处理电路，被配置为：接收第一下行控制信令，所述第一下行控制信令包括第一频域指示信息和第一波束指示信息；以及在所述第一频域指示信息所指示的频域资源和与所述第一波束指示信息所指示的波束相对应的频域资源相同的情况下，在所述频域资源上根据所述波束接收下行信息或者发送上行信息。
根据本公开的另一方面，提供了一种无线通信方法，包括：生成第一下行控制信令，其中，所述第一下行控制信令包括第一频域指示信息和第一波束指示信息，并且所述第一频域指示信息所指示的频域资源和与所述第一波束指示信息所指示的波束相对应的频域资源相同；以及向用户设备发送所述第一下行控制信令。
根据本公开的另一方面，提供了一种无线通信方法，包括：接收第一下行控制信令，所述第一下行控制信令包括第一频域指示信息和第一波束指示信息；以及在所述第一频域指示信息所指示的频域资源和与所述第一波束指示信息所指示的波束相对应的频域资源相同的情况下，在所述频域资源上根据所述波束接收下行信息或者发送上行信息。
根据本公开的另一方面，提供了一种计算机可读存储介质，包括可执行计算机指令，所述可执行计算机指令当被计算机执行时使得所述计算 机执行根据本公开所述的无线通信方法。
根据本公开的另一方面，提供了一种计算机程序，所述计算机程序当被计算机执行时使得所述计算机执行根据本公开所述的无线通信方法。
使用根据本公开的电子设备、无线通信方法和计算机可读存储介质，下行控制信令中包括频域指示信息和波束指示信息，频域指示信息指示的频域资源和与波束指示信息指示的波束相对应的频域资源相同。这样一来，可以在波束与频域资源绑定的情况下正确地对波束和频域资源进行指示，以防止频域指示信息指示的频域资源和与波束指示信息指示的波束相对应的频域资源不相同而导致用户设备无法正常接收或发送。
从在此提供的描述中，进一步的适用性区域将会变得明显。这个概要中的描述和特定例子只是为了示意的目的，而不旨在限制本公开的范围。

具体实施方式
现在参考附图来更加充分地描述本公开的例子。以下描述实质上只是示例性的，而不旨在限制本公开、应用或用途。
提供了示例实施例，以便本公开将会变得详尽，并且将会向本领域技术人员充分地传达其范围。阐述了众多的特定细节如特定部件、装置和方法的例子，以提供对本公开的实施例的详尽理解。对于本领域技术人员而言将会明显的是，不需要使用特定的细节，示例实施例可以用许多不同的形式来实施，它们都不应当被解释为限制本公开的范围。在某些示例实施例中，没有详细地描述众所周知的过程、众所周知的结构和众所周知的技术。
将按照以下顺序进行描述：
1.场景的描述；
2.网络侧设备的配置示例；
3.用户设备的配置示例；
4.方法实施例；
5.应用示例。
<1.场景的描述>
图1是示出根据本公开的实施例的每个小区被配置多个波束的场景的示意图。如图1所示，每个PCI可以对应多个波束。例如，PCI1可以对应波束1、波束2、波束3、波束4和波束5，PCI2可以对应波束6和波束7，PCI3可以对应波束8、波束9、波束10、波束12和波束14。
图2是示出根据本公开的实施例的波束与频域资源绑定的场景的示意图。图2中示出了一个NTN小区的覆盖范围。该NTN小区的覆盖范围在地理位置上被划分成多个区域。这里，虽然图2示出了每个区域的形状为六边形并且每个区域的大小相同的示例，但是本公开并不限于此。此外，该NTN小区采用了频率复用的技术，并且频率复用因子为3。也就是说，频域资源被划分为BWP1、BWP2和BWP3。相邻的区域采用不同的BWP从而避免干扰。
众所周知，网络侧设备的发射波束可以用下行参考信号标识来表示，下行参考信号包括但不限于SSB(Synchronization Signal Block，同步信号块)和CSI-RS(Channel State Information-Reference Signal，信道状态信息参考信号)。对于用于初始接入的BWP(也被称为BWP0)，所有的SSB都可以在该BWP0上传输。也就是说，用户设备通过检测BWP0上的所有SSB从而进行同步。如图2所示，SSB1、SSB2和SSB3表示的波束都可以在BWP0上传输。对于除BWP0以外的其它BWP，其与CSI-RS表示的波束具有对应关系(也被称为绑定关系)。具体地，针对特定的区域，BWP与CSI-RS表示的下行发射波束具有一一对应的关系。
如图2所示，在竖条形区域示出的BWP1中，BWP1与CSI-RS1具有绑定关系。也就是说，针对该竖条形区域中的用户设备，网络侧设备将利用BWP1和由CSI-RS1表示的下行发射波束来向该用户设备发送下行信息。再如，在横条形区域示出的BWP3中，BWP3与CSI-RS3具有绑定关系。也就是说，针对该横条形区域中的用户设备，网络侧设备将利用BWP3和由CSI-RS3表示的下行发射波束来向该用户设备发送下行信息。 又如，在网格区域示出的BWP2中，BWP2与CSI-RS2具有绑定关系。也就是说，针对该网格区域中的用户设备，网络侧设备将利用BWP2和由CSI-RS2表示的下行发射波束来向该用户设备发送下行信息。
值的注意的是，BWP与CSI-RS的一一对应关系仅针对特定的区域。例如，在图2中空白的BWP1中，可以采用除CSI-RS1表示的波束以外的其它波束，该其它波束与CSI-RS1表示的波束不相邻。
如上所述，图2以频域资源为BWP为例说明了频域资源与下行发射波束进行绑定的情形。在上行中频域资源也可以与波束进行绑定。例如，用于上行的BWP可以与用户设备的上行发射波束进行绑定。即，用户设备的上行BWP与上行发射波束具有一一对应的关系。同样地，可以用上行参考信号标识来表示上行波束，上行参考信号包括但不限于SRS(Sounding Reference Signal，测量参考信号)。
此外，图2示出了频率复用因子为3的情形，但是本公开对频率复用因子的数值不进行限制。
本公开针对这样的场景提出了一种无线通信***中的电子设备、由无线通信***中的电子设备执行的无线通信方法以及计算机可读存储介质，以在波束和频域资源绑定的情况下改进对波束和频域资源的指示过程。
根据本公开的无线通信***可以是5G NR(New Radio，新无线)通信***。进一步，根据本公开的无线通信***可以包括NTN。可选地，根据本公开的无线通信***还可以包括TN(Terrestrial network，地面网络)。
根据本公开的网络侧设备可以是任何类型的基站设备，例如可以是eNB，也可以是gNB(第5代通信***中的基站)。此外，根据本公开的网络侧设备可以位于地面上，也可以位于卫星设备上。也就是说，可以利用卫星设备为用户设备提供服务。在为用户设备提供服务的卫星设备是透明卫星设备的情况下，网络侧设备可以位于地面上；在为用户设备提供服务的卫星设备是非透明卫星设备的情况下，网络侧设备可以位于该卫星设备上。
根据本公开的用户设备可以是移动终端(诸如智能电话、平板个人计算机(PC)、笔记本式PC、便携式游戏终端、便携式/加密狗型移动路由器和数字摄像装置)或者车载终端(诸如汽车导航设备)。用户设备还 可以被实现为执行机器对机器(M2M)通信的终端(也称为机器类型通信(MTC)终端)。此外，用户设备可以为安装在上述终端中的每个终端上的无线通信模块(诸如包括单个晶片的集成电路模块)。
<2.网络侧设备的配置示例>
图3是示出根据本公开的实施例的电子设备300的配置的示例的框图。这里的电子设备300可以作为无线通信***中的网络侧设备，具体地可以作为无线通信***中的基站设备。
如图3所示，电子设备300可以包括第一生成单元310和通信单元320。
这里，电子设备300的各个单元都可以包括在处理电路中。需要说明的是，电子设备300既可以包括一个处理电路，也可以包括多个处理电路。进一步，处理电路可以包括各种分立的功能单元以执行各种不同的功能和/或操作。需要说明的是，这些功能单元可以是物理实体或逻辑实体，并且不同称谓的单元可能由同一个物理实体实现。
根据本公开的实施例，第一生成单元310可以生成第一下行控制信令。这里，第一生成单元310生成的第一下行控制信令可以包括第一频域指示信息和第一波束指示信息，并且第一频域指示信息所指示的频域资源和与第一波束指示信息所指示的波束相对应的频域资源相同。
根据本公开的实施例，电子设备300可以通过通信单元320向用户设备发送第一生成单元310生成的第一下行控制信令。
由此可见，根据本公开的实施例的电子设备300，下行控制信令中包括频域指示信息和波束指示信息，频域指示信息指示的频域资源和与波束指示信息指示的波束相对应的频域资源相同。这样一来，可以在波束与频域资源绑定的情况下正确地对波束和频域资源进行指示，以防止频域指示信息指示的频域资源和与波束指示信息指示的波束相对应的频域资源不相同而导致用户设备无法正常接收或发送。
根据本公开的实施例，第一下行控制信令可以包括用于下行调度的下行控制信令(即用于控制下行传输的信令)和用于上行调度的下行控制信令(即用于控制上行传输的信令)。在第一下行控制信令是用于下行调度的下行控制信令的情况下，第一下行控制信令包括的第一频域指示信息用于指示下行频域资源，第一下行控制信令包括的第一波束指示信息用于指示下行发射波束。类似地，在第一下行控制信令是用于上行调度的下行 控制信令的情况下，第一下行控制信令包括的第一频域指示信息用于指示上行频域资源，第一下行控制信令包括的第一波束指示信息用于指示上行发射波束。
根据本公开的实施例，频域资源包括但不限于BWP。频域指示信息可以包括频域资源的标识信息。例如，在频域资源为BWP的情况下，第一频域指示信息可以为BWP ID。
根据本公开的实施例，可以用参考信号来表示波束。例如，可以用下行参考信号来表示下行发射波束，下行参考信号例如为CSI-RS。用于指示下行发射波束的第一波束指示信息可以为TCI(Transmission Configuration Indicator，传输配置指示)状态，这是因为TCI状态与下行参考信号存在对应关系，因此根据TCI状态可以确定唯一的准共位类型D(QCL type D)的下行参考信号，从而可以确定下行发射波束。类似地，可以用上行参考信号来表示上行发射波束，上行参考信号例如为SRS。用于指示上行发射波束的第一波束指示信息可以为SpatialRelationInfo(空间关系信息)或者SRI(SRS Resource Indicator，SRS资源指示)，这是因为SpatialRelationInfo或者SRI与上行参考信号SRS存在对应关系，因此根据SpatialRelationInfo或者SRI可以确定唯一的上行参考信号，从而可以确定上行发射波束。此外，如果TCI与上行参考信号存在对应关系，则用于指示上行发射波束的第一波束指示信息也可以为TCI。
根据本公开的实施例，如图3所示，电子设备300还可以包括配置单元330，用于配置频域资源与波束之间的对应关系。根据本公开的实施例，下行频域资源与下行发射波束之间具有对应关系，而上行频域资源与上行发射波束之间具有对应关系。配置单元330可以配置这样的对应关系。进一步，电子设备300可以通过通信单元320向用户设备发送这样的对应关系。例如，电子设备300可以通过RRC信令承载这样的对应关系。
例如，在第一下行控制信令是用于下行调度的下行控制信令、频域资源为BWP、用CSI-RS来表示波束、并且用TCI状态来表示第一波束指示信息的情况下，配置单元330生成的对应关系中的一个可以如下所示。
TCI-State::＝SEQUENCE{
tci-StateId TCI#1,
qcl-Type1 QCL-Info,
}
QCL-Info::＝SEQUENCE{
bwp-Id BWP#1
referenceSignal CHOICE{
csi-rs NZP-CSI-RS-Resource#3,
},
qcl-Type ENUMERATED{typeD},
...
}
如上所述，在该对应关系中，TCI状态ID为TCI状态1，其指示的下行发射波束为CSI-RS资源3表示的下行发射波束，CSI-RS资源3所在的频域资源为BWP1。也就是说，通过这样的对应关系，用户设备可以确定CSI-RS资源3表示的下行发射波束与BWP1存在绑定关系。进一步，配置单元330生成的对应关系中可以包括多个这样对应关系，从而为用户设备配置下行发射波束与下行频域资源之间的对应关系。
以上说明了配置单元330配置下行发射波束与下行频域资源之间的对应关系的一个示例。配置单元330还可以以类似的方式为用户设备配置上行发射波束与上行频域资源之间的对应关系，本公开对此不再赘述。
根据本公开的实施例，第一下行控制信令可以是DCI(Downlink Control Information，下行控制信息)。
在DCI为用于下行调度的DCI的情况下，在配置单元330配置了下行发射波束与下行频域资源之间的对应关系之后，第一生成单元310可以生成DCI，该DCI包括BWP ID和TCI状态，并且BWP ID所指示的下行BWP与TCI状态指示的下行发射波束对应的下行BWP相同。类似地，在DCI为用于上行调度的DCI的情况下，在配置单元330配置了上行发射波束与上行频域资源之间的对应关系之后，第一生成单元310可以生成DCI，该DCI包括BWP ID和SpatialRelationInfo/SRI，并且BWP ID所指示的上行BWP与SpatialRelationInfo/SRI指示的上行发射波束对应的上行BWP相同。
在本领域中，用于下行调度的DCI中的下行BWP通常用于指示下行数据信息和下行控制信息的下行频域资源，DCI中的TCI状态通常用于指示下行数据信息的下行发射波束。由于下行BWP和TCI状态是分别指 示的，因此在下行BWP与下行发射波束进行绑定的情况下无法保证下行BWP和与TCI状态指示的下行发射波束对应的下行BWP是相同的。根据本公开的实施例，第一生成单元310在生成DCI时使得下行BWP和与TCI状态指示的下行发射波束对应的下行BWP相同，从而可以在下行BWP与下行发射波束进行绑定的情况下对下行BWP和下行发射波束进行正确的指示。这种优势对于用于上行调度的DCI同样适用。
下面将针对DCI是用于下行调度的DCI和DCI是用于上行调度的DCI两种情形来分别描述本公开的实施例。
根据本公开的实施例，在DCI为用于下行调度的DCI的情况下，可以用第一频域指示信息指示用于下行数据信息(利用PDSCH承载)和下行控制信息(利用PDCCH承载)的下行频域资源，并且可以用第一波束指示信息指示用于下行数据信息的下行发射波束。
根据本公开的实施例，电子设备300可以用隐性的方式指示用于下行控制信息的下行发射波束。例如，电子设备300和用户设备约定用于下行控制信息的下行发射波束与用于下行数据信息的下行发射波束相同。
根据本公开的实施例，如图3所示，电子设备300还可以包括处理单元340，用于确定用于发送下行数据信息和用于发送下行控制信息的下行发射波束和下行频域资源，还用于确定用户设备用于发送上行数据信息和用于发送上行控制信息的上行发射波束和上行频域资源，并根据用户设备用于发送上行数据信息和用于发送上行控制信息的上行发射波束和上行频域资源确定用于接收上行数据信息和用于接收上行控制信息的上行接收波束和上行频域资源。
根据本公开的实施例，在处理单元340确定了用于发送下行数据信息和用于发送下行控制信息的下行频域资源的情况下，电子设备300可以利用DCI中的第一频域指示信息来指示这样的下行频域资源。进一步，在处理单元340确定了用于发送下行数据信息的下行发射波束的情况下，电子设备300可以利用DCI中的第一波束指示信息来指示这样的下行发射波束。进一步，处理单元340可以确定用于发送下行控制信息的下行发射波束与用于发送下行数据信息的下行发射波束相同。
如图3所示，电子设备300还可以包括下行信息生成单元350，用于生成下行数据信息和下行控制信息。根据本公开的实施例，电子设备300可以在处理单元340确定的下行频域资源上根据处理单元340确定的下行 发射波束发送下行信息生成单元350生成的下行数据信息和下行控制信息。
例如，DCI包括TCI1和BWP1，则电子设备300可以在BWP1上利用TCI1表示的下行发射波束发送下行控制信息和下行数据信息，用户设备可以根据TCI1表示的下行发射波束确定对应的下行接收波束，并在BWP1上利用该下行接收波束接收下行控制信息和下行数据信息。
图4是示出根据本公开的实施例的对波束和频域资源进行指示的信令流程图，在图4中，基站可以由电子设备300来实现。如图4所示，在步骤S401中，基站向UE发送RRC配置，以配置下行发射波束与下行频域资源之间的绑定关系。在步骤S402中，基站向UE发送DCI，其中包括第一频域指示信息和第一波束指示信息。在步骤S403中，UE根据DCI的指示确定PDSCH的下行发射波束和下行频域资源以及PDCCH的下行频域资源，并将PDCCH的下行发射波束确定为与PDSCH的下行发射波束相同。在步骤S404中，基站向UE发送PDCCH。在步骤S405中，UE根据PDCCH的下行发射波束和下行频域资源对PDCCH进行盲检。在步骤S406中，基站向UE发送PDSCH。在步骤S407中，UE根据PDSCH的下行发射波束和下行频域资源对PDSCH进行接收。如上所示，图4示出了在DCI是用于下行调度的DCI、并且基站用隐性的方式指示PDCCH的下行发射波束的情况下对波束和频域资源进行指示的信令流程图。
根据本公开的实施例，电子设备300也可以用显性的方式来指示用于发送下行控制信息的下行发射波束。例如，下行信息生成单元350可以生成下行数据信息以使得下行数据信息包括用于指示下行控制信息的下行发射波束的波束指示信息，该下行控制信息的下行发射波束与第一波束指示信息所指示的下行发射波束相同。可选地，可以用下行数据信息中包括的MAC CE来承载用于指示下行控制信息的下行发射波束的波束指示信息。这里，用于指示下行控制信息的下行发射波束的波束指示信息也可以是TCI状态。
根据本公开的实施例，在处理单元340确定了用于发送下行数据信息和用于发送下行控制信息的下行频域资源的情况下，电子设备300可以利用DCI中的第一频域指示信息来指示这样的下行频域资源。进一步，在处理单元340确定了用于发送下行数据信息的下行发射波束的情况下，电子设备300可以利用DCI中的第一波束指示信息来指示这样的下行发射波束。进一步，处理单元340可以确定用于发送下行控制信息的下行发射波 束与用于发送下行数据信息的下行发射波束相同。而电子设备300可以利用生成单元350生成的下行数据信息中包括的波束指示信息来指示下行控制信息的下行发射波束。
根据本公开的实施例，电子设备300可以在处理单元340确定的下行频域资源上根据处理单元340确定的下行发射波束发送下行信息生成单元350生成的下行数据信息和下行控制信息。
根据本公开的实施例，在利用参考信号标识来表示波束的情况下，即用下行参考信号标识来表示第一波束指示信息所指示的波束以及用于指示下行控制信息的波束，则第一波束指示信息中包括的参考信号与用于指示下行控制信息的波束的波束指示信息中包括的参考信号可以相同。
例如，DCI包括TCI1和BWP1，则电子设备300可以在BWP1上利用TCI1表示的下行发射波束发送下行控制信息和下行数据信息，下行数据信息包括MAC CE，该MAC CE包括TCI1。DCI中的TCI1和下行数据信息中的MAC CE中的TCI1表示的参考信号标识相同。用户设备可以根据TCI1表示的下行发射波束确定对应的下行接收波束，并在BWP1上利用该下行接收波束接收下行数据信息。进一步，用户设备确定下行数据信息中包括的MAC CE中也包括TCI1，该TCI1表示的下行发射波束与DCI中的TCI1表示的下行发射波束相同，从而根据TCI1表示的下行发射波束确定对应的下行接收波束，并在BWP1上利用该下行接收波束接收下行控制信息。
根据本公开的实施例，第一波束指示信息中包括的参考信号与用于指示下行控制信息的波束的波束指示信息中包括的参考信号可以具有准共位(Quasi-Colocation,QCL)的关系。这里，两个不同的参考信号具有准共位的关系指的是：这两个参考信号不同，但是这两个参考信号所表示的波束是相同的。
例如，DCI包括TCI1和BWP1，则电子设备300可以在BWP1上利用TCI1表示的下行发射波束发送下行控制信息和下行数据信息，下行数据信息包括MAC CE，该MAC CE包括TCI2。DCI中的TCI1和下行数据信息中的MAC CE中的TCI2表示的参考信号具有准共位的关系。用户设备可以根据TCI1表示的下行发射波束确定对应的下行接收波束，并在BWP1上利用该下行接收波束接收下行数据信息。进一步，用户设备确定下行数据信息中包括的MAC CE中包括TCI2，该TCI2表示的下行发射波束与DCI中的TCI1表示的下行发射波束相同，从而根据TCI2表示的 下行发射波束确定对应的下行接收波束，并在BWP1上利用该下行接收波束接收下行控制信息。
上述的TCI1和TCI2的配置可以如下所示。
TCI-State::＝SEQUENCE{
tci-StateId TCI#1,
qcl-Type1 QCL-Info,
}
QCL-Info::＝SEQUENCE{
bwp-Id BWP#1
referenceSignal CHOICE{
csi-rs NZP-CSI-RS-Resource#3,
},
qcl-Type ENUMERATED{typeD},
...
}
TCI-State::＝SEQUENCE{
tci-StateId TCI#2,
qcl-Type1 QCL-Info,
}
QCL-Info::＝SEQUENCE{
referenceSignal CHOICE{
ssb SSB-Index#3,
},
qcl-Type ENUMERATED{typeD},
...
}
如上所述，TCI1表示的参考信号为CSI-RS资源3，TCI2表示的参 考信号为SSB3。虽然CSI-RS资源3与SSB3不同，但是CSI-RS资源3与SSB3表示的下行发射波束相同。
图5是示出根据本公开的实施例的对波束和频域资源进行指示的信令流程图，在图5中，基站可以由电子设备300来实现。如图5所示，在步骤S501中，基站向UE发送RRC配置，以配置下行发射波束与下行频域资源之间的绑定关系。在步骤S502中，基站向UE发送DCI，其中包括第一频域指示信息和第一波束指示信息。在步骤S503中，UE根据DCI的指示确定PDSCH的下行发射波束和下行频域资源以及PDCCH的下行频域资源。在步骤S504中，基站向UE发送PDSCH。在步骤S505中，UE根据PDSCH的下行发射波束和下行频域资源对PDSCH进行接收，并根据PDSCH中的MAC CE确定PDCCH的下行发射波束，该PDCCH的下行发射波束与PDSCH的下行发射波束相同。在步骤S506中，基站向UE发送PDCCH。在步骤S507中，UE根据PDCCH的下行发射波束和下行频域资源对PDCCH进行盲检。如上所示，图5示出了在DCI是用于下行调度的DCI、并且基站用显性的方式指示PDCCH的下行发射波束的情况下对波束和频域资源进行指示的信令流程图。
在本领域中，下行控制信息的下行发射波束和下行数据信息的下行发射波束是分别进行指示的，因此在只激活了一个下行BWP的情况下无法保证下行控制信息的下行发射波束和下行数据信息的下行发射波束是相同的。如上所述，根据本公开的实施例，电子设备300可以使得下行控制信息的下行发射波束与下行数据信息的下行发射波束相同，并可以利用隐性的或者显性的方式来表示下行控制信息的下行发射波束，从而确保下行控制信息的下行发射波束和下行数据信息的下行发射波束相同。
根据本公开的实施例，在存在需要调度的下行信息的情况下，第一生成单元310可以如上所述生成DCI，并根据需要调度的下行信息确定DCI中的其它字段的状态或者数值，从而用户设备可以根据该DCI进行下行数据信息和下行控制信息的接收。此外，在没有需要调度的下行信息的情况下，第一生成单元310可以如上所述生成DCI，并将除第一频域指示信息和第一波束指示信息以外的至少部分字段设置为特定值。例如，第一生成单元310可以将指示下行数据信息所在的时域和频域资源的字段、HARQ进程编号的字段等设置为特定值。特定值包括但不限于全0或全1。这样一来，用户设备可以确定该DCI仅用于指示下行频域资源和下行发射波束，而无需解调下行数据信息或者下行控制信息。
根据本公开的实施例，在DCI为用于上行调度的DCI的情况下，可以用第一频域指示信息指示用于上行数据信息(利用PUSCH承载)和上行控制信息(利用PUCCH承载)的上行频域资源，并且可以用第一波束指示信息指示用于上行数据信息的上行发射波束。
根据本公开的实施例，电子设备300可以用隐性的方式指示用于上行控制信息的上行发射波束。例如，电子设备300和用户设备约定用于上行控制信息的上行发射波束与用于上行数据信息的上行发射波束相同。
根据本公开的实施例，在处理单元340确定了用于发送上行数据信息和用于发送上行控制信息的上行频域资源的情况下，电子设备300可以利用DCI中的第一频域指示信息来指示这样的上行频域资源。进一步，在处理单元340确定了用于发送上行数据信息的上行发射波束的情况下，电子设备300可以利用DCI中的第一波束指示信息来指示这样的上行发射波束。进一步，处理单元340可以确定用于发送上行控制信息的上行发射波束与用于发送上行数据信息的上行发射波束相同。
根据本公开的实施例，电子设备300可以根据处理单元340确定的上行发射波束确定相应的上行接收波束，并可以在处理单元340确定的上行频域资源上根据上行接收波束接收上行数据信息和上行控制信息。
例如，DCI包括SpatialRelationInfo1/SRI1和BWP1，则用户设备可以在BWP1上利用SpatialRelationInfo1/SRI1表示的上行发射波束发送上行控制信息和上行数据信息，电子设备300可以根据SpatialRelationInfo1/SRI1表示的上行发射波束确定对应的上行接收波束，并在BWP1上利用该上行接收波束接收上行控制信息和上行数据信息。
图6是示出根据本公开的实施例的对波束和频域资源进行指示的信令流程图，在图6中，基站可以由电子设备300来实现。如图6所示，在步骤S601中，基站向UE发送RRC配置，以配置上行发射波束与上行频域资源之间的绑定关系。在步骤S602中，基站向UE发送DCI，其中包括第一频域指示信息和第一波束指示信息。在步骤S603中，UE根据DCI的指示确定PUSCH的上行发射波束和上行频域资源以及PUCCH的上行频域资源，并将PUCCH的上行发射波束确定为与PUSCH的上行发射波束相同。在步骤S604中，UE根据PUCCH的上行发射波束和上行频域资源向基站发送PUCCH。在步骤S605中，UE根据PUSCH的上行发射波束和上行频域资源向基站发送PUSCH。如上所示，图6示出了在DCI是用于上行调度的DCI、并且基站用隐性的方式指示PUCCH的上行发射波 束的情况下对波束和频域资源进行指示的信令流程图。
在本领域中，上行控制信息的上行发射波束和上行数据信息的上行发射波束是分别进行指示的，因此在只激活了一个上行BWP的情况下无法保证上行控制信息的上行发射波束和上行数据信息的上行发射波束是相同的。如上所述，根据本公开的实施例，电子设备300可以使得上行控制信息的上行发射波束与上行数据信息的上行发射波束相同，并可以利用隐性的方式来表示上行控制信息的上行发射波束，从而确保上行控制信息的上行发射波束和上行数据信息的上行发射波束相同。
根据本公开的实施例，在存在需要调度的上行信息的情况下，第一生成单元310可以如上所述生成DCI，并根据需要调度的上行信息确定DCI中的其它字段的状态或者数值，从而用户设备可以根据该DCI进行上行数据信息和上行控制信息的发送。此外，在没有需要调度的上行信息的情况下，第一生成单元310可以如上所述生成DCI，并将除第一频域指示信息和第一波束指示信息以外的至少部分字段设置为特定值。例如，第一生成单元310可以将指示上行数据信息所在的时域和频域资源的字段、HARQ进程编号的字段等设置为特定值。特定值包括但不限于全0或全1。这样一来，用户设备可以确定该DCI仅用于指示上行频域资源和上行发射波束，而无需发送上行数据信息或者上行控制信息。
如上所述详细描述了根据本公开的实施例的第一下行控制信令。
根据本公开的实施例，如图3所示，电子设备300还可以包括第二生成单元360，用于生成第二下行控制信令。第二下行控制信令可以包括第二波束指示信息，第二波束指示信息用于指示下行控制信息的波束或者用于指示上行控制信息的波束。
根据本公开的实施例，电子设备300可以通过通信单元320向用户设备发送第二生成单元360生成的第二下行控制信令。
根据本公开的实施例，第二下行控制信令可以为用于下行激活的下行控制信令(即用于控制下行传输的信令)，也可以为用于上行激活的下行控制信令(即用于控制上行传输的信令)。在第二下行控制信令为用于下行激活的下行控制信令的情况下，第二下行控制信令包括的第二波束指示信息用于指示下行控制信息的下行发射波束。在第二下行控制信令为用于上行激活的下行控制信令的情况下，第二下行控制信令包括的第二波束指示信息用于指示上行控制信息的上行发射波束。
与第一波束指示信息类似，第二波束指示信息可以为TCI状态，也可以为SpatialRelationInfo或者SRI。
根据本公开的实施例，第二下行控制信令可以为MAC CE。
在MAC CE为用于下行激活的MAC CE的情况下，该MAC CE包括TCI状态，该TCI状态用于指示下行控制信息的下行发射波束。类似地，在MAC CE为用于上行激活的MAC CE的情况下，该MAC CE包括SpatialRelationInfo，并且SpatialRelationInfo指示上行控制信息的上行发射波束。
下面将分别针对MAC CE为用于下行激活的MAC CE和用于上行激活的MAC CE来分别描述本公开的实施例。
在MAC CE为用于下行激活的MAC CE的情况下，根据本公开的实施例，配置单元330在确定了用于下行控制信息的下行发射波束之后，可以确定用于下行控制信息的下行频域资源为与下行控制信息的下行发射波束相对应的频域资源。进一步，配置单元330可以确定用于下行数据信息的下行频域资源与用于下行控制信息的下行频域资源相同，并且用于下行数据信息的下行发射波束与用于下行控制信息的下行发射波束相同。也就是说，电子设备300可以隐形的指示用于下行数据信息的下行频域资源和下行发射波束，即电子设备300和用户设备约定好用于下行数据信息的下行频域资源与用于下行控制信息的下行频域资源相同，用于下行数据信息的下行发射波束与用于下行控制信息的下行发射波束相同。
根据本公开的实施例，下行信息生成单元350可以生成下行控制信息和下行数据信息。电子设备300可以通过通信单元320在配置单元330确定的下行频域资源上利用配置单元330确定的下行发射波束发送下行数据信息和下行控制信息。进一步，用户设备可以根据MAC CE确定用于发送下行控制信息和下行数据信息的下行发射波束，并确定相应的下行接收波束，从而利用该下行接收波束以及下行频域资源接收下行控制信息和下行数据信息。
例如，MAC CE包括TCI状态1，该TCI状态1对应的参考信号为CSI-RS资源3，CSI-RS资源3表示的下行发射波束对应的下行频域资源为BWP1，则电子设备300可以在BWP1上利用CSI-RS资源3表示的下行发射波束发送下行控制信息和下行数据信息。
图7是示出根据本公开的实施例的对波束和频域资源进行指示的信 令流程图。在图7中，基站可以由电子设备300来实现。如图7所示，在步骤S701中，基站向UE发送RRC配置，以配置下行发射波束与下行频域资源之间的绑定关系。在步骤S702中，基站向UE发送MAC CE，其中包括第二波束指示信息。在步骤S703中，UE根据MAC CE的指示确定PDCCH的下行发射波束以及与该下行发射波束对应的下行频域资源，并将PDSCH的下行发射波束和下行频域资源确定为与PDCCH的下行发射波束相同和下行频域资源相同。在步骤S704中，基站向UE发送PDCCH。在步骤S705中，UE根据PDCCH的下行发射波束和下行频域资源对PDCCH进行盲检。在步骤S706中，基站向UE发送PDSCH。在步骤S707中，UE根据PDSCH的下行发射波束和下行频域资源对PDSCH进行接收。如上所示，图7示出了在MAC CE是用于下行激活的MAC CE的情况下对波束和频域资源进行指示的信令流程图。
在MAC CE为用于上行激活的MAC CE的情况下，根据本公开的实施例，配置单元330在确定了用于上行控制信息的上行发射波束之后，可以确定用于上行控制信息的上行频域资源为与上行控制信息的上行发射波束相对应的频域资源。进一步，配置单元330可以确定用于上行数据信息的上行频域资源与用于上行控制信息的上行频域资源相同，并且用于上行数据信息的上行发射波束与用于上行控制信息的下行发射波束相同。也就是说，电子设备300可以隐形的指示用于上行数据信息的上行频域资源和上行发射波束，即电子设备300和用户设备约定好用于上行数据信息的上行频域资源与用于上行控制信息的上行频域资源相同，用于上行数据信息的上行发射波束与用于上行控制信息的上行发射波束相同。
根据本公开的实施例，用户设备可以根据MAC CE的指示确定用于上行控制信息和上行数据信息的上行发射波束和上行频域资源，并在上行频域资源上利用上行发射波束发送上行控制信息和上行数据信息。电子设备300可以根据上行发射波束确定相应的上行接收波束，并在上行频域资源上利用上行接收波束接收上行数据信息和上行控制信息。
例如，MAC CE包括SpatialRelationInfo1，该SpatialRelationInfo1对应的参考信号为SRS资源3，SRS资源3表示的上行发射波束对应的上行频域资源为BWP1，则用户设备可以在BWP1上利用SRS资源3表示的上行发射波束发送上行控制信息和上行数据信息。
图8是示出根据本公开的实施例的对波束和频域资源进行指示的信令流程图。在图8中，基站可以由电子设备300来实现。如图8所示，在 步骤S801中，基站向UE发送RRC配置，以配置上行发射波束与上行频域资源之间的绑定关系。在步骤S802中，基站向UE发送MAC CE，其中包括第二波束指示信息。在步骤S803中，UE根据MAC CE的指示确定PUCCH的上行发射波束以及与该上行发射波束对应的上行频域资源，并将PUSCH的上行发射波束和上行频域资源确定为与PUCCH的上行发射波束相同和上行频域资源相同。在步骤S804中，UE根据PUCCH的上行发射波束和上行频域资源发送PUCCH。在步骤S805中，UE根据PUSCH的上行发射波束和上行频域资源发送PUSCH。如上所示，图8示出了在MAC CE是用于上行激活的MAC CE的情况下对波束和频域资源进行指示的信令流程图。
在本领域中，用于下行激活的MAC CE中的TCI状态通常用于指示下行控制信息的下行发射波束。因此在下行BWP与下行发射波束进行绑定的情况下无法保证下行BWP和与TCI状态指示的下行发射波束对应的下行BWP是相同的。此外，在只有一个下行BWP被激活的情况下无法保证下行控制信息的下行发射波束与下行数据信息的下行发射波束相同。根据本公开的实施例，在MAC CE指示下行控制信息的下行发射波束的情况下，电子设备300和用户设备可以约定下行控制信息的下行频域资源为与下行控制信息的下行发射波束对应的下行频域资源，并且下行数据信息的下行发射波束和下行数据信息的下行频域资源与下行控制信息相同，从而可以保证在下行发射波束与下行频域资源绑定的情况下对下行发射波束和下行频域资源的正确指示。这样的优势对于上行调度同样适用。
如上所述详细描述了根据本公开的实施例的第二下行控制信令。
根据本公开的实施例，如图3所示，电子设备300还可以包括第三生成单元370，用于生成第三下行控制信令。第三下行控制信令可以包括第三频域指示信息以及第三波束信息，第三频域指示信息用于指示下行控制信息和下行数据信息的频域资源、或者用于指示上行控制信息和上行数据信息的频域资源，第三波束指示信息用于指示下行控制信息和下行数据信息的波束、或者用于指示上行控制信息和上行数据信息的波束。
根据本公开的实施例，电子设备300可以通过通信单元320向用户设备发送第三生成单元370生成的第三下行控制信令。
根据本公开的实施例，第三下行控制信令可以包括用于下行配置的下行控制信令(即用于控制下行传输的信令)和用于上行配置的下行控制信令(即用于控制上行传输的信令)。在第三下行控制信令是用于下行配 置的下行控制信令的情况下，第三下行控制信令包括的第三频域指示信息用于指示下行数据信息和下行控制信息的下行频域资源，第三下行控制信令包括的第三波束指示信息用于指示下行控制信息和下行数据信息的下行发射波束。类似地，在第三下行控制信令是用于上行配置的下行控制信令的情况下，第三下行控制信令包括的第三频域指示信息用于指示上行控制信息和上行数据信息的上行频域资源，第三下行控制信令包括的第三波束指示信息用于指示上行控制信息和上行数据信息的上行发射波束。
根据本公开的实施例，频域资源包括但不限于BWP。频域指示信息可以包括频域资源的标识信息。例如，在频域资源为BWP的情况下，第三频域指示信息可以为BWP ID。
根据本公开的实施例，第三波束指示信息可以为TCI状态，也可以为SpatialRelationInfo或者SRI。
根据本公开的实施例，第三下行控制信令可以为RRC信令。下面将分别针对RRC信令为针对下行配置的RRC信令和针对上行配置的RRC信令来分别描述本公开的实施例。
在RRC信令为针对下行配置的RRC信令的情况下，根据本公开的实施例，电子设备300可以通过RRC信令针对每个服务小区设置默认的下行频域资源和下行发射波束。例如，电子设备300可以通过RRC信令中的firstActiveDownlinkBWP-Id字段来携带针对该服务小区的下行频域资源。此外，可以在RRC信令中新增一个TCIassociated with firstActiveDownlinkBWP-Id字段来携带针对该服务小区的下行发射波束。
根据本公开的实施例，电子设备300可以确定用户设备当前的服务小区，并将针对该服务小区设置的默认的下行发射波束确定为下行数据信息和下行控制信息的下行发射波束，将针对该服务小区设置的默认的下行频域资源确定为下行数据信息和下行控制信息的下行频域资源。进一步，电子设备300可以通过通信单元320在下行控制信息和下行数据信息的下行频域资源上根据下行控制信息和下行数据信息的下行发射波束发送下行控制信息和下行数据信息。
这样一来，在用户设备接收到RRC重配信息或者服务小区激活之后，可以根据针对该服务小区设置的默认的下行发射波束确定相应的下行接收波束，并在针对该服务小区设置的默认的下行频域资源上利用该下行接收波束接收下行数据信息和下行控制信息。
在RRC信令为针对上行配置的RRC信令的情况下，根据本公开的实施例，电子设备300可以通过RRC信令针对每个服务小区设置默认的上行频域资源和上行发射波束。例如，电子设备300可以通过RRC信令中的firstActiveUplinkBWP-Id字段来携带针对该服务小区的上行频域资源。此外，可以在RRC信令中新增一个spatialRelationInfo associated with firstActiveUplinkBWP-Id字段来携带针对该服务小区的上行发射波束。
根据本公开的实施例，电子设备300可以确定用户设备当前的服务小区，并将针对该服务小区设置的默认的上行发射波束确定为上行数据信息和上行控制信息的上行发射波束，将针对该服务小区设置的默认的上行频域资源确定为上行数据信息和上行控制信息的上行频域资源。
这样一来，在用户设备接收到RRC重配信息或者服务小区激活之后，可以在针对该服务小区设置的默认的上行频域资源上利用针对该服务小区设置的默认的上行发射波束发送上行数据信息和上行控制信息。这样一来，电子设备300可以根据上行发射波束确定相应的上行接收波束，并且在针对该服务小区设置的默认的上行频域资源上利用该上行接收波束接收上行数据信息和上行控制信息。
如上所述详细描述了根据本公开的实施例的第三下行控制信令。
如上所述，分别描述了根据本公开的实施例的第一下行控制信令(DCI)、第二下行控制信令(MAC CE)和第三下行控制信令(RRC)。本领域技术人员可以根据需求对这三种下行控制信令进行任意组合。也就是说，电子设备300可以使用上述三种下行控制信令中的一种或更多种来实现频域资源和波束的指示。下面将描述两个非限制性的示例。
例如，电子设备300通过DCI来设置下行控制信息和下行数据信息的下行频域资源、以及下行数据信息的下行发射波束，并与用户设备约定下行控制信息的下行发射波束与下行数据信息的下行发射波束相同。在需要对下行控制信息的下行发射波束进行切换的情况下，电子设备300可以通过MAC CE来通知用户设备，并与用户设备约定下行控制信息的下行频域资源也切换为与下行控制信息的下行发射波束对应的下行频域资源，下行数据信息的下行频域资源与下行控制信息的下行频域资源相同，下行数据信息的下行发射波束与下行控制信息的下行发射波束相同。
再如，电子设备300通过RRC来为每个服务小区设置默认的下行频域资源和下行发射波束。在需要对下行频域资源或者下行发射波束进行切 换的情况下，电子设备300可以通过DCI来设置下行控制信息和下行数据信息的下行频域资源、以及下行数据信息的下行发射波束，并与用户设备约定下行控制信息的下行发射波束与下行数据信息的下行发射波束相同。
由此可见，根据本公开的实施例，可以在频域资源与波束绑定的情况下对频域资源和波束进行正确的指示，并可以保持数据信息与控制信息的频域资源和波束的一致性。此外，根据本公开的实施例，可以在对现有的信令不做改动只做约束的情况下或者对现有的信令做出很小的改动的情况下实现上述目的。
<3.用户设备的配置示例>
图9是示出根据本公开的实施例的无线通信***中的用作用户设备的电子设备900的结构的框图。
如图9所示，电子设备900可以包括通信单元910、解码单元920和处理单元930。
这里，电子设备900的各个单元都可以包括在处理电路中。需要说明的是，电子设备900既可以包括一个处理电路，也可以包括多个处理电路。进一步，处理电路可以包括各种分立的功能单元以执行各种不同的功能和/或操作。需要说明的是，这些功能单元可以是物理实体或逻辑实体，并且不同称谓的单元可能由同一个物理实体实现。
根据本公开的实施例，电子设备900可以通过通信单元910接收第一下行控制信令。这里，电子设备900可以从网络侧设备，例如基站设备接收第一下行控制信令。
根据本公开的实施例，解码单元920用于对来自网络侧设备的下行数据信息或者下行控制信息进行解码。例如，解码单元920可以对第一下行控制信令进行解码以获得第一下行控制信令包括的第一频域指示信息和第一波束指示信息。
根据本公开的实施例，处理单元930可以确定用于接收信息的频域资源和波束以及用于发送信息的频域资源和波束，包括接收下行控制信息的下行接收波束和下行频域资源、接收下行数据信息的下行接收波束和下行频域资源、发送上行控制信息的上行发射波束和上行频域资源、发送上行数据信息的上行发射波束和上行频域资源。
根据本公开的实施例，在解码单元920获取了第一波束指示信息和第一频域指示信息之后，电子设备900可以确定第一频域指示信息所指示 的频域资源和与第一波束指示信息所指示的波束相对应的频域资源是否相同。进一步，在第一频域指示信息所指示的频域资源和与第一波束指示信息所指示的波束相对应的频域资源相同的情况下，处理单元930可以确定该频域资源为接收下行信息或者发送上行信息的频域资源，从而电子设备900可以通过通信单元910在该频域资源上根据第一波束指示信息指示的波束接收下行信息或者发送上行信息。
根据本公开的实施例，电子设备900可以从网络侧设备获取下行发射波束与下行频域资源之间的绑定关系以及上行发射波束与上行频域资源之间的绑定关系，例如通过RRC信令获取上述绑定关系，从而可以根据绑定关系来确定与第一波束指示信息所指示的波束相对应的频域资源。
根据本公开的实施例，在电子设备900确定第一频域指示信息所指示的频域资源和与第一波束指示信息所指示的波束相对应的频域资源不同的情况下，处理单元930可以将与第一波束指示信息所指示的波束对应的频域资源确定为接收下行信息或者发送上行信息的频域资源，从而电子设备900可以在与第一波束指示信息所指示的波束相对应的频域资源上根据第一波束指示信息所指示的波束接收下行信息或者发送上行信息。也就是说，电子设备900可以忽略第一频域指示信息所指示的频域资源，而以第一波束指示信息所指示的波束对应的频域资源为准。
如上所述，根据本公开的实施例，电子设备900可以确定第一频域指示信息所指示的频域资源是否和与第一波束指示信息指示的波束对应的频域资源相同，从而保证了在频域资源与波束绑定的情况下对频域资源和波束的正确指示。
根据本公开的实施例，第一下行控制信令可以为DCI。下面将分别针对DCI为用于下行调度的DCI和用于上行调度的DCI对本公开的实施例进行说明。
在DCI为用于下行调度的DCI的情况下，并且在第一频域指示信息所指示的频域资源和与第一波束指示信息所指示的波束相对应的频域资源相同的情况下，处理单元930可以确定下行控制信息和下行数据信息的下行频域资源为该频域资源，并且确定下行数据信息的下行发射波束为第一波束指示信息指示的波束。进一步，处理单元930可以确定下行控制信息的下行发射波束与下行数据信息的下行发射波束相同，从而可以确定下行控制信息的下行接收波束与下行数据信息的下行接收波束相同。进一步，电子设备900可以在下行控制信息的下行频域资源上利用下行控制信 息的下行接收波束接收下行控制信息，并可以在下行数据信息的下行频域资源上利用下行数据信息的下行接收波束接收下行数据信息。也就是说，电子设备900可以根据网络侧设备的隐性指示来确定下行控制信息的下行发射波束。
根据本公开的实施例，在第一频域指示信息所指示的频域资源和与第一波束指示信息所指示的波束相对应的频域资源相同的情况下，处理单元930也可以确定下行控制信息和下行数据信息的下行频域资源为该频域资源，并且确定下行数据信息的下行发射波束为第一波束指示信息指示的波束。进一步，处理单元930可以根据下行数据信息的下行发射波束确定相应的下行接收波束，并在下行数据信息的下行频域资源上根据下行数据信息的下行接收波束接收下行数据信息。进一步，解码单元920可以对下行数据信息进行解码以确定用于指示下行控制信息的下行发射波束的波束指示信息。这里，电子设备900可以确定下行控制信息的下行发射波束与第一波束指示信息所指示的波束是否相同。进一步，在下行控制信息的下行发射波束与第一波束指示信息所指示的波束相同的情况下，处理单元930可以确定下行控制信息的下行发射波束为该下行发射波束。进一步，电子设备900可以根据下行控制信息的下行发射波束确定相应的下行接收波束，并在下行控制信息的下行频域资源上利用该下行接收波束接收下行控制信息。也就是说，电子设备900可以根据网络侧设备的显性指示来确定下行控制信息的下行发射波束。
根据本公开的实施例，在利用参考信号标识来表示第一波束指示信息所指示的波束以及用于指示下行控制信息的波束的情况下，电子设备900可以根据下述方式来确定下行控制信息的下行发射波束与第一波束指示信息所指示的波束是否相同。具体地，在第一波束指示信息中包括的参考信号与用于指示下行控制信息的下行发射波束的波束指示信息中包括的参考信号相同或者具有准共位的关系的情况下，电子设备900可以确定下行控制信息的下行发射波束与第一波束指示信息所指示的波束相同。
如图9所示，电子设备900还可以包括延迟时间确定单元940，用于在下行频域资源与下行发射波束发生变化的情况下确定延迟时间。根据本公开的实施例，当来自网络侧设备的下行控制信令所指示的下行频域资源与之前的下行频域资源不同时，可以认为下行频域资源发生了变化。类似地，当来自网络侧设备的下行控制信令所指示的下行发射波束与之前的下行发射波束不同时，可以认为下行发射波束发生了变化。
在电子设备900根据网络侧设备的隐性指示来确定下行控制信息的下行发射波束的情况下，当下行频域资源与下行发射波束发生变化时，延迟时间确定单元940可以根据频域资源切换的时延和波束切换的时延中的至少一者确定延迟时间。进一步，延迟时间确定单元940可以将频域资源切换的时延和波束切换的时延中的较大值确定为延迟时间。
根据本公开的实施例，电子设备900在不晚于接收到第一下行控制信令之后的延迟时间内，切换下行频域资源和下行发射波束。这里，切换下行频域资源指的是电子设备900的处理单元930将用于接收下行信息的下行频域资源由原来的下行频域资源切换为新的下行频域资源，切换下行发射波束指的是电子设备900的处理单元930确定新的用于发送下行信息的下行发射波束，并根据新的下行发射波束确定相应的新的下行接收波束。
这里，频域资源切换的时延例如可以为BWP gap(BWP间隔)、BWP switch delay(BWP切换时延)等参数，波束切换的时延例如可以为TCI gap(TCI间隔)、timeDurationForQCL(QCL时间段)等参数。
根据本公开的实施例，在电子设备900根据网络侧设备的显性指示来确定下行控制信息的下行发射波束并且电子设备900不需要对下行数据信息进行反馈的情况下，延迟时间确定单元940可以根据频域资源切换的时延和波束切换的时延中的至少一者确定延迟时间。进一步，延迟时间确定单元940可以将频域资源切换的时延和波束切换的时延中的较大值确定为延迟时间。

根据本公开的实施例，电子设备900可以通过通信单元910向网络侧设备发送反馈信息，并在不晚于发送反馈信息之后的延迟时间内，切换下行频域资源和下行发射波束。
在本领域中，下行频域资源的切换和下行发射波束的切换是分开执行的。也就是说，在频域资源切换的时延之前切换下行频域资源，在波束切换的时延之前切换下行发射波束。根据本公开的实施例，完善了在频域资源与波束绑定的情况下频域资源和波束的切换时序。
在DCI为用于上行调度的DCI的情况下，并且在第一频域指示信息所指示的频域资源和与第一波束指示信息所指示的波束相对应的频域资源相同的情况下，处理单元930可以确定上行控制信息和上行数据信息的上行频域资源为该频域资源，并且确定上行数据信息的上行发射波束为第一波束指示信息指示的波束。进一步，处理单元930可以确定上行控制信息的上行发射波束与上行数据信息的上行发射波束相同。进一步，电子设备900可以在上行控制信息的上行频域资源上利用上行控制信息的上行发射波束发送上行控制信息，并可以在上行数据信息的上行频域资源上利用上行数据信息的上行发射波束发送上行数据信息。也就是说，电子设备900可以根据网络侧设备的隐性指示来确定上行控制信息的上行发射波束。
根据本公开的实施例，延迟时间确定单元940还可以在上行频域资源与上行发射波束发生变化的情况下确定延迟时间。根据本公开的实施例，当来自网络侧设备的下行控制信令所指示的上行频域资源与之前的上行频域资源不同时，可以认为上行频域资源发生了变化。类似地，当来自网络侧设备的下行控制信令所指示的上行发射波束与之前的上行发射波束不同时，可以认为上行发射波束发生了变化。
当上行频域资源与上行发射波束发生变化时，延迟时间确定单元940可以根据频域资源切换的时延和波束切换的时延中的至少一者确定延迟时间。进一步，延迟时间确定单元940可以将频域资源切换的时延和波束切换的时延中的较大值确定为延迟时间。
