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2019年1月9日提交中国专利局、申请号为201910020174.7、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带宽块(Bandwidth Part，BWP)切换技术。更具体地，涉及一种用于无线通信的电子设备和方法以及计算机可读存储介质。
背景技术
新无线电(New Radio，NR)作为针对长期演进(Long Term Evolution，LTE)的下一代的无线接入方式，是与LTE不同的无线接入技术(Radio Access Technology，RAT)。NR是能够应对包括增强移动宽带(Enhanced mobile broadband，eMBB)、大规模机器类型通信(Massive machine type communications，mMTC)以及超可靠和低延迟通信(Ultra reliable and low latency communications，URLLC)的各种用例(use case)的接入技术。
由于NR的新特征比如更宽的带宽、灵活的配置等，在NR中引入了BWP的概念。这是因为，一些用户设备(User Equipment，UE)可能不需要如此宽的带宽或者不能支持如此宽的带宽，因此通过BWP技术使其仅利用一部分带宽，从而提高了系统的灵活性和兼容性。并且，BWP技术还可以降低UE的能耗。在NR中，分配给一个次系统的带宽可以动态变化，因此会涉及BWP之间的切换。对于非授权频段上的通信而言，由于需要执行信道检测以确定待切换到的频段是否可用，因此比授权频段上的BWP切换的过程更为复杂。
发明内容
在下文中给出了关于本发明的简要概述，以便提供关于本发明的某些方面的基本理解。应当理解，这个概述并不是关于本发明的穷举性概述。它并不是意图确定本发明的关键或重要部分，也不是意图限定本发明的范围。其目的仅仅是以简化的形式给出某些概念，以此作为稍后论述的更详细描述的前序。
根据本申请的一个方面，提供了一种用于无线通信的电子设备，包括：处理电路，被配置为：从基站获取针对非授权频段上的特定BWP的多个控制资源集合的信息，其中，所述多个控制资源集合分布在所述特定BWP中的以预定带宽划分的各个带宽单位中；以及基于至少一个控制资源集合来执行物理下行控制信道的接收。
根据本申请的另一个方面，提供了一种用于无线通信的方法，包括：从基站获取针对非授权频段上的特定BWP的多个控制资源集合的信息，其中，所述多个控制资源集合分布在所述特定BWP中的以预定带宽划分的各个带宽单位中；以及基于至少一个控制资源集合来执行物理下行控制信道的接收。
根据本申请的一个方面，提供了一种用于无线通信的电子设备，包括：处理电路，被配置为：生成针对非授权频段上的特定BWP的多个控制资源集合的信息，其中，所述多个控制资源集合分布在所述特定BWP中的以预定带宽划分的各个带宽单位中；以及将所述多个控制资源集合的信息提供给用户设备。
根据本申请的另一个方面，提供了一种用于无线通信的方法，包括：生成针对非授权频段上的特定BWP的多个控制资源集合的信息，其中，所述多个控制资源集合分布在所述特定BWP中的以预定带宽划分的各个带宽单位中；以及将所述多个控制资源集合的信息提供给用户设备。
依据本发明的其它方面，还提供了用于实现上述用于无线通信的方法的计算机程序代码和计算机程序产品以及其上记录有该用于实现上述用于无线通信的方法的计算机程序代码的计算机可读存储介质。
根据本申请的电子设备和方法通过将多个控制资源集合分布在BWP中的各个带宽单位中，可以将非授权频段上的BWP间的切换精确到带宽单位，提高了灵活性。

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，BWP是NR中引入的新技术。当BWP应用于非授权频段时，由于非授权频段资源利用的非连续性比如设置有最大信道占用时 间(Maximum Channel Occupancy Time，MCOT)和机会性比如存在与其他通信系统共存而引起的竞争，用户对于BWP的占用是不确定的。用户在使用BWP的资源进行通信时，需要首先进行信道检测以确认当前信道是可用的。例如在当前BWP不能满足通信要求时，用户可能需要切换到其他的BWP来继续通信，其中，切换表示当前BWP的去激活和其他BWP的激活。在信道检测指示该其他BWP仅有一部分可用时，期望仍然能够切换到该部分进行通信，并且期望能够快速高效地进行切换和控制信息的传输。本实施例意在至少部分地解决这些问题。
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，被配置为生成针对非授权频段上的特定BWP的多个控制资源集合(Control Resource Set，CORESET)的信息，其中，所述多个CORESET分布在特定BWP中的以预定带宽划分的各个带宽单位中；以及提供单元102，被配置为将所述多个CORESET提供给用户设备。
其中，生成单元101和提供单元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100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。这同样适用于随后关于基站侧的电子设备其他配置示例的描述。
CORESET是NR中新引入的概念，其指示物理下行控制信道(Physical downlink control channel，PDCCH)的频域和时域的范围。在一个示例中，CORESET的信息比如CORESET的时域参数和频域参数可以经由无线资源控制(Radio Resource Control，RRC)信令来提供给UE。
在本实施例中，以预定带宽将特定BWP划分为多个带宽单位，在每个带宽单位中均分布有CORESET。这样，可以缩小PDCCH盲检的范围，减小计算负荷。作为示例，预定带宽可以为20MHz，其中，还可以以20MHz为单位来执行信道检测比如先听后说(Listen Before Talk，LBT)。
图2示出了BWP中的多个CORESET的示例图。其中，BWP被分为6个带宽单位，每一个带宽单位的带宽范围为20MHz，且每一个带宽单位中分布有CORESET，在图中用斜线填充部分示出。应该理解，图2所示的BWP和带宽单位仅是示例，并不限于此。
UE在执行PDCCH的接收时，可以基于单个带宽单位的CORESET来执行，从而使得盲检范围限于一个带宽单位中。
在非授权频段上执行BWP切换时，例如期望由当前BWP切换到新BWP(例如，上述特定BWP)，需要先对该新BWP进行信道检测比如LBT。相应地，如图3所示，电子设备100还可以包括执行单元103，被配置为对特定BWP执行信道检测，并且在信道检测的结果指示特定BWP至少部分可用的情况下将非授权频段上的通信切换到特定BWP。
对于具体的切换过程，可以先执行针对新BWP的LBT，然后执行基于下行控制信息(Downlink Control Information，DCI)的触发或者基于定时器的触发来切换到新BWP。图4示出了该切换机制下基站侧的操作的一个示意图，其中，当前BWP为BWP1，带宽为20MHz，新BWP为BWP2，带宽为120MHz。
在执行切换时，首先对BWP2执行LBT，具体地，以20MHz带宽为单位执行LBT。在LBT指示至少一个带宽单位可用的情况下，基站使用当前BWP向UE发送DCI以触发切换，随后切换到新BWP。可以看出，在该过程中，需要执行多达3次的射频切换，即，从当前BWP切换到新BWP执行LBT，切换回来发送DCI以及最终切换到新BWP，而这会引起较长的切换时延Y。在该过程中，DCI例如用于向UE指示新BWP的指示符(indicator)，以使得UE能够获知将切换到哪个BWP。
在一个示例中，为了减少射频切换的次数，可以省略上述DCI的发送，而是采用预配置的方式来通知UE新的BWP。例如，生成单元101还被配置为生成预配置BWP切换表，提供单元102将其提供给UE，以 使得UE在要执行BWP切换的情况下，按照预配置BWP切换表中的BWP切换顺序确定要切换到的BWP。在基站侧，同样按照该预配置BWP切换表来执行BWP切换，从而可以在不发送DCI的情况下，基站和UE切换到同一BWP。在该示例中，上述特定BWP为要切换到的BWP。上述预配置的BWP切换表可以经由RRC信令提供给UE。
图5示出了在省略DCI的情况下BWP切换的示意图。与图4相比，图5的示例中不需要切换回当前BWP发送DCI以及最终切换到新BWP的操作，从而可以减少射频切换的次数，减小时延。
此外，在LBT完成的定时与实际传输开始之间的时段内，为了保留相应的信道，提供单元102可以在新BWP上发送信道占用信号，比如伪(Dummy)信号，如图5中的点填充部分所示。
在该示例中，虽然针对每一个带宽单位中分布有CORESET的BWP进行了描述，但是并不限于此，省略DCI而采用预配置的方式来通知UE新的BWP的方案也可以应用于任何其他BWP。
在另一个示例中，基站保留基于DCI的触发，即，生成单元101生成DCI，提供单元102将其提供给UE。并且，为了支持BWP中的非连续频率资源分配，该DCI中包括新BWP(即，上述特定BWP)的指示符以及一个或多个带宽单位的指示信息。UE接收到该DCI信息中，可以获知将要切换到哪个BWP的哪个或哪些带宽单位上，并且基于例如经由RRC信令获取的CORESET的信息来在相应带宽单位上接收PDCCH。
在基站以带宽单位为单位对新BWP执行LBT时，LBT的结果可能指示有些带宽单位可用，而有些带宽单位被占用，可用的带宽单位可能是不连续的，如图6所示，其中，第1个和第4个带宽单位上的LBT结果指示相应的带宽单位被占用。在这种情况下，上述DCI可以包含指示该结果的指示信息并提供给UE，以使得UE可以不监视第1个和第4个带宽单位。
例如，上述指示信息可以用比特数等于带宽单位的数量的位图表示。在图6的示例中，例如可以将指示信息设置为011011，UE在收到该指示信息后，可以解析出第1个和第4个带宽单位不可用。应该理解，指示信息的格式并不限于此，而是可以采用其他任何格式。
另外，返回参照图5，当针对新BWP的LBT的结果指示某些带宽单位被占用时，基站可以不在这些带宽单位上发送信道占用信号。
另一方面，在非授权频段上执行BWP切换时，还可以先执行基于DCI的触发或者基于定时器的触发然后执行信道检测。在这种情况下，为了使得DCI的指示与信道检测结果所检测到的实际能够使用的频段更一致，可以采用两次DCI通知的方案，即，基站先通过一个DCI通知新的BWP的指示符，然后执行LBT，在LBT完成后通过另一个DCI通知可以接入的一个或多个带宽单位的指示信息。
例如，生成单元101生成第一DCI，该第一DCI包含新BWP(即，上述特定BWP)的指示符；提供单元102将该第一DCI提供给UE；执行单元103对新BWP执行信道检测；生成单元102生成第二DCI，该第二DCI包含新BWP的信道检测结果指示可用的一个或多个带宽单位的指示信息；以及提供单元102将该第二DCI提供给UE。
为了便于理解，图7示出了上述两次DCI通知的方案的基站侧的操作的示意图。如图所示，针对BWP2的LBT结果指示第1和第4带宽单位不可用，因此第二DCI中可以包含指示该结果的信息，随后基站切换到BWP2的第2、3、5和6个带宽单位。
综上所述，通过在BWP的每个带宽单位中分布CORESET，可以将非授权频段上的BWP间的切换精确到带宽单位，提高了调度的灵活性，并且还降低了PDCCH盲检的复杂度，降低了时延。
<第二实施例>
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200的功能模块框图。如图8所示，该电子设备200包括：获取单元201，被配置为从基站获取针对非授权频段上的BWP的多个CORESET的信息，其中，所述多个CORESET分布在该特定BWP中的以预定带宽划分的各个带宽单位中；以及执行单元202，被配置为基于至少一个CORESET来执行PDCCH的接收。
其中，获取单元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。并且，应该理解，图8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200例如可以设置在用户设备(UE)侧或者可通信地连接到UE。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。这同样适用于随后关于用户设备侧的电子设备的其他配置示例的描述。
例如，获取单元201可以经由RRC信令来获取所述多个CORESET的信息。例如，特定BWP为要切换到的BWP，UE在获取到其多个CORESET的信息之后，可以解析出各个带宽单位中PDCCH的时频资源位置，从而可以根据至少一个CORESET来执行PDCCH的接收。与第一实施例中相同，带宽单位的预定带宽可以为20MHz。
在非授权频段上执行BWP切换时，可以先执行信道检测比如LBT，然后执行基于DCI或定时器的触发。在一个示例中，基站在执行LBT之后不发送DCI来通知要切换到的BWP，获取单元101可以从基站获取预配置BWP切换表，该切换表中包含预先确定的BWP切换的顺序，执行单元102在要执行BWP切换的情况下，按照该预配置BWP切换表中的BWP切换顺序确定要切换到的BWP。在基站侧，同样按照该预配置BWP切换表来执行BWP切换，从而可以在不发送DCI的情况下，基站和UE切换到同一BWP。在该示例中，上述特定BWP为要切换到的BWP。即，获取单元101获取要切换到的BWP的多个CORESET的信息。此外，获取单元101可以经由RRC信令来获取预配置BWP切换表。
在另一个示例中，基站保留基于DCI的触发，相应地，获取单元101被配置为从基站获取DCI，并且为了支持BWP中的非连续频率资源分配，该DCI中包括新BWP(即，上述特定BWP)的指示符以及一个或多个带宽单位的指示信息，执行单元102根据该DCI将非授权频段上的通信切换到新BWP的一个或多个带宽单位上。例如，上述指示信息可 以用比特数等于带宽单位的数量的位图表示。
另一方面，在非授权频段上执行BWP切换时，还可以先执行基于DCI的触发或者基于定时器的触发然后执行信道检测。在这种情况下，为了使得DCI的指示与信道检测结果所检测到的实际能够使用的频段更一致，可以采用两次第一实施例中所述的两次DCI通知的方案。
相应地，获取单元101被配置为：接收来自基站的第一DCI，该第一DCI包含新BWP(即，上述特定BWP)的指示符；接收来自基站的第二DCI，该第二DCI包含新BWP的第一或多个带宽单位的指示信息。执行单元102被配置为根据第一DCI和第二DCI将非授权频段上的通信切换到新BWP的一个或多个带宽单位上。
综上所述，通过在BWP的每个带宽单位中分布CORESET，可以将非授权频段上的BWP间的切换精确到带宽单位，提高了调度的灵活性，并且还降低了PDCCH盲检的复杂度，降低了时延。

本领域的技术人员应当理解，这种存储介质不局限于图18所示的其中存储有程序、与设备相分离地分发以向用户提供程序的可移除介质1811。可移除介质1811的例子包含磁盘(包含软盘(注册商标))、光盘(包含光盘只读存储器(CD-ROM)和数字通用盘(DVD))、磁光盘(包含迷你盘(MD)(注册商标))和半导体存储器。或者，存储介质可以是ROM 1802、存储部分1808中包含的硬盘等等，其中存有程序，并且与包含它们的设备一起被分发给用户。
还需要指出的是，在本发明的装置、方法和系统中，各部件或各步骤是可以分解和/或重新组合的。这些分解和/或重新组合应该视为本发明的等效方案。并且，执行上述系列处理的步骤可以自然地按照说明的顺序按时间顺序执行，但是并不需要一定按时间顺序执行。某些步骤可以并行或彼此独立地执行。
最后，还需要说明的是，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者设备所固有的要素。此外，在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括所述要素的过程、方法、物品或者设备中还存在另外的相同要素。
以上虽然结合附图详细描述了本发明的实施例，但是应当明白，上面所描述的实施方式只是用于说明本发明，而并不构成对本发明的限制。对于本领域的技术人员来说，可以对上述实施方式作出各种修改和变更而没有背离本发明的实质和范围。因此，本发明的范围仅由所附的权利要求及其等效含义来限定。
