具体实施方式
下面将参照附图来说明本公开的实施例。在本公开的一个附图或一种实施方式中描述的元素和特征可以与一个或更多个其它附图或实施方式中示出的元素和特征相结合。应当注意，为了清楚的目的，附图和说明 中省略了与本公开无关的、本领域普通技术人员已知的部件和处理的表示和描述。
下面参照图1说明根据本公开的一个实施例的用于无线通信的电子装置的配置示例。如图1所示，根据本实施例的用于无线通信的电子装置100包括处理电路110。处理电路110例如可以实现为特定芯片、芯片组或者中央处理单元(CPU)等。
根据本实施例的电子装置例如可以实现在用户设备(UE)侧。
处理电路110包括第一控制单元111和第二控制单元113。需要指出，虽然附图中以功能块的形式示出了第一控制单元111和第二控制单元113，然而应理解，各单元的功能也可以由处理电路作为一个整体来实现，而并不一定是通过处理电路中分立的实际部件来实现。另外，虽然图中以一个框示出处理电路，然而电子装置可以包括多个处理电路，并且可以各单元的功能分布到多个处理电路中，从而由多个处理电路协同操作来执行这些功能。
第一控制单元111被配置为进行控制以从基站接收关于带宽块集合的指示信息，该带宽块集合包括一个或更多个带宽块。
第二控制单元113被配置为进行控制以利用带宽块集合中的至少一个带宽块与基站通信。
例如，指示信息可以被包含在无线资源控制(RRC)信令中，并且指示信息可以指示被配置的带宽块的集合。在这种情况下，UE例如可以以免授权(grant-free)的方式通过所配置的多个带宽块中选择用于进行上行传输的带宽块。
或者，指示信息可以被包含在下行控制信息(DCI)中，并且指示信息可以指示被激活的带宽块的集合。在这种情况下，由基站侧在所配置的多个带宽块中确定被激活的一个或多个带宽块，并将被激活的带宽块的集合通知给UE。
被激活的带宽块为被配置的带宽块的子集，被激活的带宽块的集合数量取决于被配置的带宽块的数量。相应地，指示信息的位宽度可以是基于被配置的带宽块的数量确定的。
在描述根据本公开实施例的针对BWP集合的指示信息之前，作为比 较示例，首先描述DCI中用于指示BWP的指示信息的位宽度的确定方式。
用于指示BWP的指示信息的位宽度可以被确定为
Figure PCTCN2020070370-appb-000001
其中
Figure PCTCN2020070370-appb-000002
表示上取整。在n BWP,RRC≤3的情况下可以设置n BWP＝n BWP,RRC+1，在这种情况下，BWP指示相当于高层参数BWP-ID。或者，可以设置n BWP＝n BWP,RRC，假设所配置的BWP的数量为4，可以如下面的表1定义BWP指示。

BWP指示字段的值(2比特) BWP
00 由高层配置的第一BWP
01 由高层配置的第二BWP
10 由高层配置的第三BWP
11 由高层配置的第四BWP
与上面描述的针对BWP的指示信息不同，根据本实施例的指示信息所指示的是BWP的集合，其中每个集合可以包括一个或多个BWP。
同样假设所配置的BWP的数量为4，则BWP集合的数量为15。相应地，可以将指示信息的位宽度设置为4，并且例如可以如下面的表2定义BWP集合指示。
表2
指示字段的值(4比特) BWP集合
0000 由高层配置的第一BWP
0001 由高层配置的第二BWP
0010 由高层配置的第三BWP
0011 由高层配置的第四BWP
0100 第一和第二BWP
0101 第一和第三BWP
0110 第一和第四BWP

1100 第一和第三和第四BWP
1101 第二和第三和第四BWP
1110 第一和第二和第三和第四BWP
1111 保留
需要指出，BWP集合的指示信息的设置不限于上述示例，而是可以根据多种方式设置。例如，也可以以类似于位图的方式定义BWP集合指示，其中每个位对应于所配置的一个BWP，当某个位的值为1时表示相应的BWP被激活，如下面的表3所示。

0011 第三和第四BWP
1110 第一和第二和第三BWP
1101 第一和第二和第四BWP
1011 第一和第三和第四BWP
0111 第二和第三和第四BWP
1111 第一和第二和第三和第四BWP
0000 保留
上面说明了实施例中与多BWP的配置和激活有关的内容，接下来说明与利用多个BWP进行传输有关的内容。
根据一个实施例，第一控制单元111可以被配置为进行控制以检测目标带宽块上的前导信号或信道，该前导信号或信道包含与目标带宽块的未来占用时长有关的信息。
第二控制单元113可以被配置为进行控制以将与未来占用时长有关的信息通知给基站。除了与未来占用时长有关的信息之外，还可以将与目标带宽块的拥堵程度有关的信息通知给基站。
进一步地，第二控制单元113还可以被配置为进行控制以接收下行传输，该下行传输是基站基于目标带宽块的未来占用时长而发送的。
也就是说，UE可以通过检测前导信号或信道来起到报告信道可用性的作用，从而例如可以帮助基站进行BWP的选择以及相应CCA定时的选择等。通过这样做，例如在确定相同的或不同的信道接入技术(RAT)长期占用特定信道的情况下，基站可以省略进行不必要的信道检测，从而提高处理效率。
该过程可以被看作一种具有信道占用时长指示的增强的前导检测。顺带提及，可以只在由于LBT(先侦听后传输)失败而未能进行下行传输的BWP处进行前导检测，而能量检测可以应用于所试图接入的全部BWP。
信道占用信息的具体形式可以根据前导的类型而不同。例如，可以定义增强的新无线(NR)信道或信号，其指示占据信道的RAT内装置的例 如信道占用时长和拥堵水平。此外，前导的类型还可以包括例如802.11a/802.11ax前导，其中也可以指示占据信道的RAT内装置的信道占用时长和拥堵水平。
接下来更具体地说明根据信道占用信息进行下行传输的示例方式。
根据一个实施例，如果目标带宽块的占用结束时间比下行传输的计划开始时间晚一个时隙以内，则可以通过部分时隙传输(partial slot transmission)在目标带宽块上进行下行传输。如果目标带宽块的占用结束时间比下行传输的计划开始时间晚超过一个时隙，则不通过目标带宽块进行下行传输，即，可以舍弃对该目标带宽块的使用。
参照图9A和图9B的示例，其中图9A示出了在用户没有提供信道占用信息的情况下的传输示例，图9B示出了在用户提供信道占用信息的情况下的传输示例。
如图9A所示，在用户没有提供信道占用信息的情况下，在上行传输前，UE对各带宽块进行LBT，其中BWP#1的部分以及BWP#2的LBT失败，因此不在BWP#1和BWP#2上进行上行传输。类似地，在下行传输前，基站对各带宽块进行LBT，其中BWP#2的LBT失败，因此不在BWP#2上进行下行传输。
对于用户提供信道占用信息的情况，如图9B所示，在上行传输前，UE对各带宽块进行LBT，其中BWP#1的部分以及BWP#2的LBT失败，因此不在BWP#1和BWP#2上进行上行传输。然而，UE通过BWP#0向基站发送信道占用信息，其中指示BWP#1的信道占用时间，并且UE通过BWP#3向基站发送信道占用信息，其中指示BWP#2的信道占用时间。根据信道占用信息，基站可以确定BWP#1和BWP#2的信道占用停止时间。
由于BWP#1的占用结束时间比下行传输的计划开始时间早，因此基站可以在不进行LBT的情况下在BWP#1上进行下行传输。
另外，尽管图中未示出，如果BWP#1的占用结束时间比下行传输的计划开始时晚一个时隙以内，则可以通过部分时隙传输在BWP#1上进行下行传输。
对于BWP#2，由于其占用结束时间比下行传输的计划开始时间晚超过 一个时隙，因此基站不通过BWP#2进行下行传输。
此外，在获得了与未来占用时长有关的信息的情况下，基站可以基于目标带宽块的占用结束时间与下行传输的计划开始时间之间的间隔来确定是否针对目标带宽块进行用于下行传输的信道检测。
例如，如果UE的检测结果指示没有其他设备在占据目标带宽块，则基站可以不进行信道检测而直接使用目标带宽块继续下行传输。
此外，基站可以基于目标带宽块的占用结束时间与下行传输的计划开始时间之间的间隔来确定所要进行的信道检测的类型。作为示例，存在以下LBT类型：CAT1LBT,即不执行LBT；CAT2LBT,即执行LBT，不执行随机回退；CAT3LBT,即执行LBT，回退竞争窗大小固定；CAT4LBT,即执行LBT，回退竞争窗大小可变。
可以定义以下间隔：根据UE检测的前导信号而确定的目标带宽块的占用结束时间与所指定的下行传输的开始时间之间的间隔。例如，如果该间隔小于16μm，则可以在不进行LBT的情况下立即进行下行传输；如果该间隔小于在16μm与25μm之间，则可以进行单次的(one shot)LBT；如果该间隔>25μm，则可以进行CAT4LBT。需要指出，上述示例仅仅是说明性的而非限制性的。
上面描述的下行传输可以是在用户设备与基站对带宽块集合的共享占用时间(shared COT)内进行的。
该共享占用时间可以是由用户设备获得并共享给基站的。例如，在图9A和图9B所示的示例中，信道占用时间由UE获取，并且被分享给基站用于下行传输。
此外，共享占用时间也可以是由基站获得并共享给用户设备的。
参见图10A和图10B，其中图10A示出了在用户没有提供信道占用信息的情况下的传输示例，图10B示出了在用户提供信道占用信息的情况下的传输示例。
如图10A所示，信道占用时间由基站获取用于下行传输，并且分享给UE进行上行传输。在用户没有提供信道占用信息的情况下，在下行传输前，基站对各带宽块进行LBT，其中BWP#1的部分以及BWP#2的LBT失败，因此不在BWP#1和BWP#2上进行下行传输。接下来，在上行传 输前，UE对各带宽块进行LBT，并进行上行传输。然后，当在该信道占用时间内再次进行下行传输前，基站对各带宽块进行LBT，其中BWP#1的部分以及BWP#2的LBT失败，因此不在BWP#1和BWP#2上进行下行传输。
对于用户提供信道占用信息的情况，如图10B所示，在下行传输前，基站对各带宽块进行LBT，其中BWP#1的部分以及BWP#2的LBT失败，因此不在BWP#1和BWP#2上进行下行传输。接下来，在上行传输前，UE对各带宽块进行LBT，并进行上行传输。在该过程中，UE通过BWP#1向基站发送信道占用信息，其中指示BWP#1的信道占用时间，并且UE通过BWP#2向基站发送信道占用信息，其中指示BWP#2的信道占用时间。根据信道占用信息，基站可以确定BWP#1和BWP#2的信道占用停止时间。
当在该信道占用时间内再次进行下行传输时，由于BWP#1的占用结束时间比下行传输的计划开始时晚一个时隙以内，因此可以通过部分时隙传输在BWP#1上进行下行传输。
对于BWP#2，由于其占用结束时间比下行传输的计划开始时间晚超过一个时隙，因此基站不通过BWP#2进行下行传输。
需要指出，上述示例仅仅是说明性的而非限制性的。
此外，根据一个实施例，第二控制单元113可以被配置为进行控制以通过除目标带宽块之外的另一带宽块发送与未来占用时长有关的信息。
该另一带宽块包括与目标带宽块具有预设对应关系的带宽块，使得基站能够基于预定对应关系确定所述目标带宽块。
例如，该预设对应关系可以包括相邻关系。再次参照图9B，UE通过BWP#0向基站发送信道占用信息，其中指示与BWP#0相邻的BWP#1的信道占用时间，并且UE通过BWP#3向基站发送信道占用信息，其中指示BWP#3相邻的BWP#2的信道占用时间。此外，UE发送的指示信息中例如可以包括指示位以表明所BWP的邻接方向。或者，可以设置轮转的对应关系，例如通过BWP#0指示BWP#1的占用信息，通过BWP#1指示BWP#2的占用信息，通过BWP#2指示BWP#3的占用信息，通过BWP#3指示BWP#0的占用信息。
需要指出，预设对应关系不限于上述示例，而是可以包括任意预先设定的对应关系，只要其使得基站能够根据发送指示信息的BWP确定目标BWP即可。
此外，根据一个实施例，第二控制单元113还可以被配置为在利用目标带宽块进行上行传输的情况下，进行控制以发送前导信号或信道，该前导信号或信道包含与对目标带宽块的未来占用时长有关的信息。从而，其他装置能够确定当前装置对目标带宽块的占用情况。
此外，根据一个实施例，可以由基站确定目标带宽块的未来占用时长，并将目标带宽块的未来占用时长有关的指示信息发送至用户设备，例如，通过DCI以及/或者RRC信令向用户设备发送未来占用时长有关的指示信息，以便用户设备进行相应的数据传输。具体地，例如，基站通过向用户设备发送如RRC信令的高层信令以为用户设备配置多个带宽块，将被激活的带宽块的指示信息包含于下行控制信息中并通知给用户设备，以及确定被激活的目标带宽块的未来占用时长，并将未来占用时长的指示信息包含于下行控制信息中发送至用户设备，其中，未来占用时长对应于一定数量的时隙。

如果目标带宽块的占用结束时间比下行传输的计划开始时间晚一个时隙以内，则可以通过部分时隙传输在目标带宽块上进行下行传输。如果目标带宽块的占用结束时间比下行传输的计划开始时间晚超过一个时隙，则不通过目标带宽块进行下行传输。
根据一个实施例，第二控制单元113还可以被配置为基于目标带宽块的占用结束时间与下行传输的计划开始时间之间的间隔来确定是否针对目标带宽块进行用于下行传输的信道检测，并且/或者确定信道检测的类型。

[关于基站的应用示例]
图8是示出可以应用本公开内容的技术的gNB的示意性配置的示例的框图。gNB 2300包括一个或多个天线2310以及基站设备2320。基站设备2320和每个天线2310可以经由射频(RF)线缆彼此连接。
天线2310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2320发送和接收无线信号。如图8所示，gNB 2300可以包括多个天线2310。例如，多个天线2310可以与gNB 2300使用的多个频带兼容。虽然图8示出其中gNB 2300包括多个天线2310的示例，但是gNB 2300也可以包括单个天线2310。
基站设备2320包括控制器2321、存储器2322、网络接口2323以及无线通信接口2325。
