Description

用于无线通信的电子设备和方法、计算机可读存储介质
本申请要求于2018年7月31日提交中国专利局、申请号为201810867254.1、发明名称为“用于无线通信的电子设备和方法、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
本申请涉及无线通信技术领域，具体地涉及非授权频段上的传输技术。更具体地，涉及用于无线通信的电子设备、方法以及计算机可读存储介质。
背景技术
用户设备(User Equipment，UE)在接入非授权频段需要执行信道检测比如先听后说(Listen Before Talk，LBT)以确定非授权信道是否空闲。在信道检测指示非授权信道空闲的情况下，UE才能成功接入非授权频段来进行传输。如果信道检测指示非授权信道被占用，则UE需要随机回退并再次执行信道检测，直到信道检测指示非授权信道空闲。但是，对于一些延迟敏感的场景比如超可靠低延时通信(Ultra Reliable and Low Latency Communication，URLLC)，这是不合适的。
在UE接入非授权频段后，例如可以持续占用信道达最大信道占用时间(Maximum Channel Occupancy Time，MCOT)的长度。
此外，在非正交多址接入(Non-Orthogonal Multiple Access，NOMA)架构中，多个UE可以接入相同的时频资源。

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。

<第一实施例>
图1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1所示，该电子设备100包括：生成单元101，在UE成功接入非授权频段的情况下，生成表示是否允许与其他UE共享该UE的COT的指示；以及发送单元102，被配置为将该指示发送至基站或其他UE。
其中，生成单元101和发送单元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。并且，应该理解，图1中所示的装置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。这同样适用于随后要描述的其他电子设备的示例。
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可以工作为用户设备本身，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。这同样适用于随后要描述的其他电子设备的示例。
在非授权频段上，在UE要发送数据的情况下，其执行信道检测比如LBT，当LBT指示信道空闲时，UE接入非授权频段。此时，UE可以使用非授权信道进行最长时间为MCOT的数据传输。但是，在一些情况下，UE可能只有很短的上行传输突发，从而只需要占用短于MCOT的时间。本申请的电子设备100可以将该MCOT中剩余的时间共享给其他UE，从而提高了非授权频段的资源利用效率。
例如，共享包括其他UE在本UE的COT内接入本UE所接入的频谱资源而不执行信道检测或仅执行简化版本的信道检测。在本申请中，为了便于区分，本UE指的是提供共享COT的UE，其他UE是共享该COT的UE。例如，本UE在接入非授权频段时，可能需要执行Cat 4 LBT，其他UE在共享本UE的COT时可以仅执行25μs LBT或者不执行LBT，这取决于其他UE与本UE之间的传输间隔。该共享可以通过基站调度来实现，也可以由本UE通过直通链路(sidelink)指示其他UE来实现。
在一个示例中，发送单元102可以将上述指示包含在上行控制信息(Uplink Control Information，UCI)中，以发送至基站。例如，可以在UCI中增加1比特信息位来用于该指示。当该信息位为1时，表示允许与其他UE共享本UE的COT，当该信息位为0时，表示不允许与其他UE共享本UE的COT，或者进行相反的定义。或者，可以复用UCI中的COT共享指示来发送所述指示，其中，COT共享指示表示是否允许基站共享UE的COT来发送控制指令。即，UCI中的COT共享指示本来用于指示基站是否能够共享本UE的COT来发送下行控制信息比如针对本UE的ACK/NACK等，在本实施例中，该COT共享指示还用于指示是否允许其他UE共享本UE的COT。例如，当该COT共享指示设置为1时，表示允许基站和其他UE共享本UE的COT，当该COT共享指示设置为0时，表示不允许基站和其他UE共享本UE的COT，或者进行相反的定义。
此外，在允许与其他UE共享本UE的COT的情况下，发送单元102还被配置为将本UE的MCOT持续时段、最大信道占用截止时间、优先级、可用于共享的时隙中的至少一个的信息发送至基站。例如，这些信息可以包括在UCI中以发送至基站。基站使用这些信息为其他UE以及/或者基站本身调度本UE的剩余COT。基站和/或其他UE在本UE的COT内接入本UE的频谱资源时，可以不执行信道检测或者仅执行简化 版本的信道检测，从而能够降低延迟，满足对延时敏感的业务的需求，同时也提高了非授权频段的资源利用效率。
在另一个示例中，发送单元102还可以将是否允许其他UE共享COT的指示直接发送给其他UE。例如，可以通过在两个UE之间的D2D链接来实现这一点。发送单元102可以将上述指示包括在直通链路控制信息(Sidelink Control Information，SCI)中发送给其他UE。此外，以上所述的本UE的MCOT持续时段、最大信道占用截止时间、优先级、可用于共享的时隙中的至少一个的信息也可以包括在SCI中发送给其他UE。其他UE在接收到来自本UE的SCI中的指示之后，可以确定是否能够共享本UE的COT，并且在能够共享的情况下，在本UE的COT内接入本UE的频谱资源进行数据传输而不执行信道检测或者仅执行简化版本的信道检测。
综上所述，根据本实施例的电子设备100能够通过表示是否允许与其他UE共享本UE的COT的指示与其他UE共享COT，一方面提高了非授权频段的频谱效率，另一方面提供了一种低延迟传输的方式。
<第二实施例>
图2示出了根据本申请的另一个实施例的用于无线通信的电子设备200的功能模块框图，如图2所示，该电子设备200包括：获取单元201，被配置为从成功接入非授权频段的UE获取表示是否允许其他UE共享本UE的COT的指示；以及调度单元202，被配置为在所述指示表示允许其他UE共享本UE的COT的情况下，在COT内为其他UE调度本UE所接入的频谱资源。
类似地，获取单元201和调度单元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。并且，应该理解，图2中所示的装置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可以设置在基站侧或者可通信地连接到基站。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，用户设备、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，获取单元201通过UCI来获取所述指示。例如，该指示可以用UCI中增加的1比特信息位来表示。该该信息位为1时，表示允许与其他UE共享本UE的COT，当该信息位为0时，表示不允许与其他UE共享本UE的COT，或者进行相反的定义。或者，与第一实施例中类似地，也可以复用UCI中的COT共享指示来发送所述指示。当该COT共享指示设置为1时，表示允许基站和其他UE共享本UE的COT，当该COT共享指示设置为0时，表示不允许基站和其他UE共享本UE的COT，或者进行相反的定义。
此外，获取单元201还可以从UE获取该UE的MCOT持续时段、最大信道占用截止时间、优先级、可用于共享的时隙中的至少一个的信息，以供调度单元202在调度时使用。
在上述指示表示允许其他UE和/或者基站共享本UE的COT的情况下，调度单元202例如在本UE的剩余COT内为其他UE或基站调度本UE所接入的频谱资源，基站或其他UE可以不执行信道检测或者仅执行简化版本的信道检测而接入该频谱资源。
此外，调度单元202还可以被配置为通过下行控制信息(Downlink Control Information，DCI)向其他UE指示要共享本UE的COT，换言之，通知其他UE随后要接入的时频资源是由已经进行了信道检测的UE提供用于共享的，以使得其他UE在所共享的COT内接入频谱资源时不执行信道检测或者仅执行简化版本的信道检测。
为了便于理解，图3示出了UE2和基站共享UE1的COT的一个示意图。如图3所示，UE1通过执行Cat 4 LBT而成功接入非授权频段并完成上行传输，该上行传输可以是自发上行链路(Autonomous uplink transmission，AUL)传输，也可以是调度上行链路(Scheduled uplink transmission，SUL)传输。此时，UE1的MCOT还没有结束，UE1希望与其他UE共享其COT，因此例如通过UCI中包括的指示来通知基站。在图3所示的示例中，UE1还允许与基站共享其COT。因此，基站接入UE1的频谱资源来进行下行传输，图3中示出了基站在进行下行传输之 前执行了25μs LBT，但是这仅是一个示例，基站也可以不执行LBT。是否执行LBT例如可以取决于UE1的上行传输与基站的下行传输之间的间隔。基站的下行传输例如发送DCI，包括对UE1的上行传输的反馈以及对UE2的控制和调度信息等，或者，基站也可以发送下行数据。接下来，UE2在基站的调度下接入UE1的频谱资源来进行上行传输。类似地，UE2可以执行25μsLBT或者不执行LBT。
此外，图4示出了UE2共享UE1的COT的一个示意图。图4与图3的区别在于基站不共享UE1的COT，UE2的下行调度可能是基站通过接入其他频谱资源来实现的，因此图4中的斜线填充部分表示没有执行传输的时间段。
图5示出了UE1和UE2处于D2D连接中的情况下，UE2共享UE1的COT的一个示意图。在该示例中，UE1通过SCI指示UE2可以共享UE1的COT，以使得UE2可以接入UE1的频谱资源而仅需执行25μs LBT或者不执行LBT。
根据本实施例的电子设备200能够实现多个UE之间的COT共享，从而提高了非授权频段的频谱利用效率，并减小了时延。
<第三实施例>
图6示出了根据本申请的另一个实施例的用于无线通信的电子设备300的功能模块框图，如图6所示，电子设备300包括：生成单元301，被配置为在UE成功接入非授权频段的情况下，生成表示在MCOT内是否支持多个切换点的指示，其中，切换点表示上行传输和下行传输之间的切换；以及发送单元302，被配置为将该指示包括在UCI中，以发送至基站。
类似地，生成单元301和发送单元302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。电子设备300例如可以设置在UE侧或者可通信地连接到UE。
这里，通过在MCOT内支持多个切换点，可以实现更灵活的传输。在一个示例中，发送单元302被配置为在UCI中增加1比特信息位来用于上述指示。该该信息位为1时，表示支持多个切换点，该信息位为0 时，表示不支持多个切换点，或者进行相反的定义。另外，也可以复用UCI中的COT共享指示来发送该指示，其中，COT共享指示表示是否允许基站共享UE的COT来发送控制指令。例如，当该COT共享指示设置为1时，表示支持多个切换点，当该COT共享指示设置为0时，表示不支持多个切换点，或者进行相反的定义。
在所述指示表示在MCOT内支持多个切换点的情况下，发送单元302还将UE的MCOT持续时段、最大信道占用截止时间、优先级、可用于共享的时隙中的至少一个的信息发送至基站。这些信息例如可以包含在UCI中。
当所述指示表示支持多个切换点时，同时意味着本UE允许其他UE和基站共享本UE的COT，这些UE和基站在接入本UE所接入的频谱资源时不执行信道检测或者执行简化版本的信道检测。
此外，在基站的调度下，除了其他UE，本UE也可以在MCOT范围内再次接入本UE所接入的频谱资源。本UE再次接入该频谱资源时不执行信道检测或者执行简化版本的信道检测。图7示出了UE1再次接入UE1之前所接入的频谱资源的一个示例的示意图。可以看出，在基站执行完下行传输之后，UE1再次接入频谱资源进行上行传输，此时UE1可以不执行LBT或者执行25μs LBT。在图7的示例中，存在两个切换点，但是并不限于此，还可以存在更多的切换点。
根据本实施例的电子设备300可以支持在MCOT内存在多个切换点，从而实现对频谱资源的更灵活的使用，提高频谱利用效率。
<第四实施例>
图8示出了根据本申请的另一个实施例的用于无线通信的电子设备400的功能模块框图，如图8所示，电子设备400包括：获取单元401，被配置为从成功接入非授权频段的UE获取表示在MCOT内是否支持多个切换点的指示，其中，切换点表示上行传输和下行传输之间的切换；以及调度单元402，被配置为基于该指示在MCOT内进行UE所接入的频谱资源的调度。
类似地，获取单元401和调度单元402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。电子设备400例如可以设置在基站侧或者可通信地连接到基站。
在一个示例中，所述指示用UCI中增加的1比特信息位来表示。该该信息位为1时，表示支持多个切换点，该信息位为0时，表示不支持多个切换点，或者进行相反的定义。另外，所述指示也可以用UCI中的COT共享指示来表示，其中，COT共享指示表示是否允许基站共享UE的COT来发送控制指令。例如，当该COT共享指示设置为1时，表示支持多个切换点，当该COT共享指示设置为0时，表示不支持多个切换点，或者进行相反的定义。
此外，在所述指示表示支持多个切换点的情况下，获取单元401还被配置为从UE获取其MCOT持续时段、最大信道占用截止时间、优先级、可用于共享的时隙中的至少一个的信息。这些信息例如可以包含在UCI中。
如第三实施例中所述，支持多个切换点意味着允许多个UE共享一个UE的COT。相应地，调度单元402为其调度所述频谱资源的UE在接入该频谱资源时不执行信道检测或者执行简化版本的信道检测。例如，调度单元402还被配置为通过DCI来指示被调度的UE在MCOT内接入频谱资源时不执行信道检测或者执行简化版本的信道检测。此外，如图7所示，被调度的UE可以是发送支持多个切换点的指示的UE，也可以是其他UE。
根据本实施例的电子设备400能够支持MCOT内的多个切换点，从而实现对频谱资源的更灵活的使用，提高频谱利用效率。
<第五实施例>
图9示出了根据本申请的另一个实施例的用于无线通信的电子设备500的功能模块框图，如图9所示，电子设备500包括：获取单元501，被配置为在第一NOMA-UE成功接入非授权频段的情况下，获取第一NOMA-UE的COT共享信息；以及提供单元502，被配置为将COT共享信息提供给要接入相同的频谱资源的至少一个第二NOMA-UE，以使得至少一个NOMA-UE在第一NOMA-UE的COT内接入频谱资源而不执行信道检测或者仅执行简化版本的信道检测。
类似地，获取单元501和提供单元502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。电子设备500例如可以设置在基站侧或者可通信地连接到基站。
如前所述，在NOMA架构中，多个UE可以使用相同的时频资源进行数据传输。因此，在非授权频段中，当一个UE的信道检测指示信道可用时，使用相同的时频资源的其他UE可以共享该UE的COT，即在该UE的COT内可以接入与该UE相同的频谱资源而不执行信道检测或者执行简化版本的信道检测。应该理解，本实施例中的第一NOMA-UE和第二NOMA-UE仅是为了区分提供COT共享的NOMA-UE与执行COT-共享(即共享其他UE的COT)的NOMA-UE，并不具有顺序上的或其他方面的含义。
相应地，获取单元501从成功接入非授权频段的第一NOMA-UE获取其COT共享信息。在一个示例中，COT共享信息可以包括如下中的一个或多个：MCOT持续时段、最大信道占用截止时间、优先级、可用于共享的时隙。COT共享信息例如可以包括在UCI中。
其中，提供单元502可以被配置为通过物理下行控制信道(Physical Downlink Control Channel，PDCCH)或者广播信道向至少一个第二NOMA-UE提供COT共享信息。当通过PDCCH提供COT共享信息时，该COT共享信息例如可以包含在DCI中。当通过广播信道提供COT共享信息时，该COT共享信息例如可以包括在广播消息中。
其中，至少一个第二NOMA-UE可以与第一NOMA-UE同时尝试接入非授权频段，也可以在第一NOMA-UE之后尝试接入非授权频段。换言之，基站可以同时为第一NOMA-UE与至少一个第二NOMA-UE调度相同的频谱资源，也可以先为第一NOMA-UE调度该频谱资源，随后为至少第二NOMA-UE调度该频谱资源。
在至少一个第二NOMA-UE与第一NOMA-UE同时尝试接入非授权频段的情况下，这些NOMA-UE例如可以同时执行信道检测。为了便于理解，图10示出了同时尝试接入的情况下，各个NOMA-UE的操作的示例。在图10中，共有N个UE同时尝试接入。
非限定性地，例如第一NOMA-UE(图10中示出为UE1)的信道检测(图10中为LBT)首先成功，即其LBT结果指示信道空闲，从而 第一NOMA-UE首先成功接入非授权频段，根据本实施例，第一NOMA-UE将其COT共享信息提供给获取单元501。提供单元502随后将该COT共享信息提供给其他NOMA-UE，即至少一个第二NOMA-UE(图10中示出为UE2至UEN)。至少一个第二NOMA-UE根据该COT共享信息接入所调度的频谱资源而不再执行信道检测或者仅执行简化版本的信道检测。
此外，这里虽然示出了提供单元502向至少一个第二NOMA-UE提供COT共享信息的示例，但是并不限于此，替代地，提供单元502还可以被配置为向至少一个第二NOMA-UE提供指示接入的信息。至少一个第二NOMA-UE在接收到该指示接入的信息后，可以接入所调度的频谱资源而不再执行信道检测或者仅执行简化版本的信道检测。从图10中可以看出，UE2至UEN的MCOT可以小于或者等于UE1的MCOT。
为了进一步提高效率，提供单元502还被配置为指示第一NOMA-UE和至少一个第二NOMA-UE设置定时器，在定时器期满时第一NOMA-UE还未成功接入非授权频段的情况下，至少一个第二NOMA-UE确定不进行COT共享。换言之，在定时器期满后，至少一个第二NOMA-UE不再共享其他NOMA-UE的COT。其中，定时器的定时时长例如可以由提供单元502进行指定。此外，为了实现这一功能，还可以由提供单元502在基站侧设置定时器，在接收到COT共享信息时定时器已经过期的情况下，提供单元502不向任何NOMA-UE提供COT共享信息以及/或者指示接入的信息。
作为另一个示例，提供单元502还可以被配置为向第一NOMA-UE和至少一个第二NOMA-UE指示其要执行的信道检测的类型。其中，第一NOMA-UE被指示执行完整的信道检测，至少一个第二NOMA-UE被指示执行简化版本的信道检测或者不执行信道检测。其中，提供单元502可以根据NOMA-UE的能力指示其要执行的信道检测的类型，或者随机地指定。
仍然参照图10的示例，例如UE1被指示执行完整的LBT，其他UE被指示执行25μs LBT或者不执行LBT(即图10中的UE2至UEN的LBT可以省略或者与UE1的LBT具有不同的类型)。在这种情况下，至少一个第二NOMA-UE等待第一NOMA-UE的信道检测完成并经由基站获取来自第一NOMA-UE的COT共享信息。
类似地，为了进一步提高效率，提供单元502也可以被配置为指示第一NOMA-UE和至少一个第二NOMA-UE设置定时器，在定时器期满时第一NOMA-UE还未成功接入非授权频段的情况下，至少一个第二NOMA-UE确定不进行COT共享。或者，为了实现这一功能，还可以由提供单元502在基站侧设置定时器，在接收到COT共享信息时定时器已经过期的情况下，提供单元502不向任何NOMA-UE提供COT共享信息以及/或者指示接入的信息。此时，至少一个第二NOMA-UE自行执行信道检测。
在另一种场景下，第一NOMA-UE首先尝试接入非授权频段，至少一个第二NOMA-UE随后尝试接入非授权频段，换言之，基站在不同的定时处调度第一NOMA-UE和至少一个第二NOMA-UE。图11示出了这种NOMA-UE不同时尝试接入的情况下，各个NOMA-UE的操作的示例。
在图11的示例中，UE1首先进行LBT并成功接入信道，在经过一段时间之后，UEN、UE3和UE2等相继要接入信道。在UE1的MCOT内，UE2至UEN可以不执行LBT而直接接入信道。
相应地，本实施例也公开了一种NOMA-UE侧的装置，该装置可以包括提供单元，被配置为在信道检测指示信道空闲的情况下向基站提供COT共享信息。此外，该NOMA-UE侧的装置还可以包括获取单元，被配置为获取来自基站的COT共享信息或者指示接入的信息，以在不执行信道检测或者仅执行简化版本的信道检测的情况下接入频谱资源。
在一个示例中，该NOMA-UE侧的装置还包括定时器，被配置为在接收到来自基站的调度时启动定时器并且在定时器期满时启动信道检测。
类似地，提供单元和获取单元以及定时器均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。
根据本实施例的电子设备500能够实现被调度了相同的频谱资源的多个NOMA-UE之间的COT共享。
<第六实施例>
图12示出了根据本申请的另一个实施例的用于无线通信的电子设备600的功能模块框图，如图12所示，电子设备600包括：信道检测单元601，被配置为通过信道检测使得电子设备600所在的第一NOMA-UE尝试接入非授权频段；以及发送单元602，被配置为在第一NOMA-UE成功接入非授权频段的情况下，通过PSCCH向至少一个第二NOMA-UE发送第一NOMA-UE的COT共享信息，其中，至少一个第二NOMA-UE基于该COT共享信息在第一NOMA-UE的COT内接入与第一NOMA-UE相同的频谱资源，而不执行信道检测或者仅执行简化版本的信道检测。
类似地，信道检测单元601和发送单元602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。电子设备600例如可以设置在UE侧或者可通信地连接到UE。
该实施例与第五实施例的区别在于，第一NOMA-UE通过D2D通信中的直通链路向至少一个第二NOMA-UE发送COT共享信息。因此，COT共享信息通过PSCCH进行传输。
例如，COT共享信息可以包括在SCI中进行传输。例如，COT共享信息可以包括如下中的一个或多个：MCOT持续时段、最大信道占用截止时间、优先级、可用于共享的时隙。此外，COT共享信息还可以包括该共享的COT所针对的时频资源的信息。
在D2D场景中，PSCCH传输使用从预定资源池中选择的资源并且UE被分配时频资源用来发送或检测PSCCH。当至少一个第二NOMA-UE检测PSCCH时，如果接收到来自UE1的COT共享信息，则可以接入相应的时频资源开始上行传输而不执行信道检测或者执行简化版本的信道检测。
此外，如图12中的虚线框所示，电子设备600还可以包括：接收单元603，被配置为经由PSCCH接收来自第二NOMA-UE的共享信息，并且，电子设备600基于该共享信息来接入频谱资源而不执行信道检测或者仅执行简化版本的信道检测。根据本实施例的电子设备能够应用于以上参照图10和图11所示的同时尝试接入和不同时尝试接入的两种场景。
本实施例的电子设备600能够实现被调度了相同的频谱资源的多个 NOMA-UE之间的COT共享。
<第七实施例>

类似地，该指示可以用UCI中增加的1比特信息位表示，或者用UCI中的COT共享指示来表示。
此外，上述方法还可以包括：通过DCI指示被调度的UE在MCOT内接入所述频谱资源时不执行信道检测或者执行简化版本的信道检测。
图17示出了根据本申请的另一个实施例的用于无线通信的方法的流程图，如图17所示，该方法包括：在第一NOMA-UE成功接入非授权频段的情况下，获取第一NOMA-UE的COT共享信息(S51)；以及将该COT共享信息提供给要接入相同的频谱资源的至少一个第二NOMA-UE，以使得至少一个第二NOMA-UE在第一NOMA-UE的COT内接入所述频谱资源而不执行信道检测或仅执行简化版本的信道检测(S52)。该方法可以在基站侧执行。

[关于基站的应用示例]
(第一应用示例)
图19是示出可以应用本公开内容的技术的eNB或gNB的示意性配置的第一示例的框图。注意，以下的描述以eNB作为示例，但是同样可以应用于gNB。eNB 800包括一个或多个天线810以及基站设备820。基站设备820和每个天线810可以经由RF线缆彼此连接。
天线810中的每一个均包括单个或多个天线元件(诸如包括在多输入多输出(MIMO)天线中的多个天线元件)，并且用于基站设备820发 送和接收无线信号。如图19所示，eNB 800可以包括多个天线810。例如，多个天线810可以与eNB 800使用的多个频带兼容。虽然图19示出其中eNB 800包括多个天线810的示例，但是eNB 800也可以包括单个天线810。
基站设备820包括控制器821、存储器822、网络接口823以及无线通信接口825。
控制器821可以为例如CPU或DSP，并且操作基站设备820的较高层的各种功能。例如，控制器821根据由无线通信接口825处理的信号中的数据来生成数据分组，并经由网络接口823来传递所生成的分组。控制器821可以对来自多个基带处理器的数据进行捆绑以生成捆绑分组，并传递所生成的捆绑分组。控制器821可以具有执行如下控制的逻辑功能：该控制诸如为无线资源控制、无线承载控制、移动性管理、接纳控制和调度。该控制可以结合附近的eNB或核心网节点来执行。存储器822包括RAM和ROM，并且存储由控制器821执行的程序和各种类型的控制数据(诸如终端列表、传输功率数据以及调度数据)。
网络接口823为用于将基站设备820连接至核心网824的通信接口。控制器821可以经由网络接口823而与核心网节点或另外的eNB进行通信。在此情况下，eNB 800与核心网节点或其他eNB可以通过逻辑接口(诸如S1接口和X2接口)而彼此连接。网络接口823还可以为有线通信接口或用于无线回程线路的无线通信接口。如果网络接口823为无线通信接口，则与由无线通信接口825使用的频带相比，网络接口823可以使用较高频带用于无线通信。
无线通信接口825支持任何蜂窝通信方案(诸如长期演进(LTE)和LTE-先进)，并且经由天线810来提供到位于eNB 800的小区中的终端的无线连接。无线通信接口825通常可以包括例如基带(BB)处理器826和RF电路827。BB处理器826可以执行例如编码/解码、调制/解调以及复用/解复用，并且执行层(例如L1、介质访问控制(MAC)、无线链路控制(RLC)和分组数据汇聚协议(PDCP))的各种类型的信号处理。代替控制器821，BB处理器826可以具有上述逻辑功能的一部分或全部。BB处理器826可以为存储通信控制程序的存储器，或者为包括被配置为执行程序的处理器和相关电路的模块。更新程序可以使BB处理器826的功能改变。该模块可以为插入到基站设备820的槽中的卡或刀 片。可替代地，该模块也可以为安装在卡或刀片上的芯片。同时，RF电路827可以包括例如混频器、滤波器和放大器，并且经由天线810来传送和接收无线信号。
如图19所示，无线通信接口825可以包括多个BB处理器826。例如，多个BB处理器826可以与eNB 800使用的多个频带兼容。如图19所示，无线通信接口825可以包括多个RF电路827。例如，多个RF电路827可以与多个天线元件兼容。虽然图19示出其中无线通信接口825包括多个BB处理器826和多个RF电路827的示例，但是无线通信接口825也可以包括单个BB处理器826或单个RF电路827。
在图19所示的eNB 800中，电子设备200、400和500的收发器可以由无线通信接口825实现。功能的至少一部分也可以由控制器821实现。例如，控制器821可以通过执行获取单元201和调度单元202的功能来实现已成功接入非授权频段的UE的COT的共享，可以通过执行获取单元401和调度单元402的功能来支持MCOT内的多个切换点，可以通过执行获取单元501和提供单元502的功能实现多个NOMA-UE之间的COT共享。
(第二应用示例)
图20是示出可以应用本公开内容的技术的eNB或gNB的示意性配置的第二示例的框图。注意，类似地，以下的描述以eNB作为示例，但是同样可以应用于gNB。eNB 830包括一个或多个天线840、基站设备850和RRH 860。RRH 860和每个天线840可以经由RF线缆而彼此连接。基站设备850和RRH 860可以经由诸如光纤线缆的高速线路而彼此连接。
天线840中的每一个均包括单个或多个天线元件(诸如包括在MIMO天线中的多个天线元件)并且用于RRH 860发送和接收无线信号。如图20所示，eNB 830可以包括多个天线840。例如，多个天线840可以与eNB 830使用的多个频带兼容。虽然图20示出其中eNB 830包括多个天线840的示例，但是eNB 830也可以包括单个天线840。
基站设备850包括控制器851、存储器852、网络接口853、无线通信接口855以及连接接口857。控制器851、存储器852和网络接口853与参照图19描述的控制器821、存储器822和网络接口823相同。
无线通信接口855支持任何蜂窝通信方案(诸如LTE和LTE-先进)，并且经由RRH 860和天线840来提供到位于与RRH 860对应的扇区中的终端的无线通信。无线通信接口855通常可以包括例如BB处理器856。除了BB处理器856经由连接接口857连接到RRH 860的RF电路864之外，BB处理器856与参照图19描述的BB处理器826相同。如图20所示，无线通信接口855可以包括多个BB处理器856。例如，多个BB处理器856可以与eNB 830使用的多个频带兼容。虽然图20示出其中无线通信接口855包括多个BB处理器856的示例，但是无线通信接口855也可以包括单个BB处理器856。
