本申请主张在2017年10月20日在中国提交的中国专利申请No.201710984041.2的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，尤其涉及一种非授权频段下的信息传输方法、终端及网络设备。
背景技术
在未来第五代(5th Generation，5G)通信系统中，或称为新空口(New Radio，NR)系统中，非授权频段(unlicensed band)可以作为授权频段(licensed band)的补充，以帮助运营商对服务进行扩容。为了与NR部署保持一致，并尽可能的最大化基于NR的非授权接入，非授权频段可以工作在5GHz、37GHz和60GHz频段。非授权频段的大带宽(80MHz或者100MHz)能够减小网络设备和终端的实施复杂度。由于非授权频段由多种无线接入技术(Radio Access Technology，RATs)共用，例如WiFi、雷达、长期演进授权频谱辅助接入(Long Term Evolution License Assisted Access，LTE-LAA)等，因此在某些国家或者区域，非授权频段在使用时必须符合某些规定(regulation)以保证所有设备可以公平的使用该资源，例如先听后说(Listen Before Talk，LBT)，最大信道占用时间(Maximum Channel Occupancy Time，MCOT)等规则。
在NR系统中，每个载波最大的信道带宽(Channel Bandwidth)可达到400MHz。但是考虑到终端能力，终端支持的最大带宽可以小于400MHz，且终端可以工作在多个小的带宽部分(Bandwidth Part，BWP)上。每个带宽部分对应于一个数值配置(Numerology)、带宽(Bandwidth)、频域位置(Frequency Location)。网络设备可以为终端配置多于一个BWP，这时网络设备需要告诉终端在哪一个BWP上工作，即激活(activate)哪一个BWP。BWP的激活或 去激活可以通过下行控制信息(Downlink Control Information，DCI)信令指示，终端在收到激活或去激活指令后，在相应的激活BWP(active BWP)上进行传输。其中，在非授权频段上，网络设备或者终端在激活BWP上传输前也需要进行信道侦听，当信道为空时，才可传输信息。当只针对激活的BWP进行信道侦听时，若侦听到信道为忙，则网络设备或者终端不能进行传输，但网络设备为终端配置其他未激活的BWP可能会空闲，这部分资源将会被浪费。
发明内容
本公开实施例提供了一种非授权频段下的信息传输方法、终端及网络设备，以解决相关技术中由于仅侦听激活的BWP，而造成其他可用但未激活的BWP资源浪费的问题。
第一方面，本公开实施例提供了一种非授权频段下的信息传输方法，应用于终端，包括：
对非授权频段中的第一带宽部分BWP的传输信道进行侦听，得到信道侦听结果；其中，第一BWP为接收到的上行授权调度信息和/或上行传输资源预配置信息对应的至少一个BWP；
若信道侦听结果指示第一BWP中存在传输信道空闲的BWP，则在传输信道空闲的BWP中选取至少一个BWP进行激活，得到第一激活BWP；
在第一激活BWP上，向网络设备发送信息。
第二方面，本公开实施例还提供了一种终端，包括：
第一侦听模块，用于对非授权频段中的第一带宽部分BWP的传输信道进行侦听，得到信道侦听结果；其中，第一BWP为接收到的上行授权调度信息和/或上行传输资源预配置信息对应的至少一个BWP；
第一处理模块，用于若信道侦听结果指示第一BWP中存在传输信道空闲的BWP，则在传输信道空闲的BWP中选取至少一个BWP进行激活，得到第一激活BWP；
第一发送模块，用于在第一激活BWP上，向网络设备发送信息。
第三方面，本公开实施例提供了一种终端，终端包括处理器、存储器以 及存储于存储器上并可在处理器上运行的计算机程序，计算机程序被处理器执行时实现上述的非授权频段下的信息传输方法的步骤。
第四方面，本公开实施例提供了一种非授权频段下的信息传输方法，应用于网络设备，包括：
向终端发送用于指示非授权频段中至少一个BWP的上行授权调度信息和/或上行传输资源预配置信息；
在所述至少一个BWP上接收终端发送的信息。
第五方面，本公开实施例提供了一种网络设备，包括：
配置模块，用于向终端发送用于指示非授权频段中至少一个BWP的上行授权调度信息和/或上行传输资源预配置信息；
第二接收模块，用于在所述至少一个BWP上接收终端发送的信息。
第六方面，本公开实施例提供了一种网络设备，网络设备包括处理器、存储器以及存储于存储器上并可在处理器上运行的计算机程序，处理器执行计算机程序时实现上述的非授权频段下的信息传输方法的步骤。
第七方面，本公开实施例提供了一种计算机可读存储介质，计算机可读存储介质上存储有计算机程序，计算机程序被处理器执行时实现上述的非授权频段下的信息传输方法的步骤。
这样，本公开实施例的非授权频段下的信息传输方法、终端及网络设备中，终端在非授权频段上针对多个配置的BWP进行侦听，在信道为空的BWP上进行传输。对于上行传输，终端在上行授权调度的至少一个BWP上进行侦听，对传输信道空闲的BWP进行激活得到第一激活BWP，并在第一激活BWP上向网络设备发送上行信息。这样通过对多个BWP进行侦听，在一个BWP忙时还可利用其它BWP进行传输，从而提高资源利用率。

如图1所示，本公开实施例的非授权频段下的信息传输方法，应用于终端，包括以下步骤：
步骤11：对非授权频段中的第一带宽部分BWP的传输信道进行侦听，得到信道侦听结果。
其中，第一BWP为接收到的上行授权调度信息和/或上行传输资源预配置信息对应的至少一个BWP；第一BWP指的是网络设备为终端调度或配置的BWP，指的是BWP的类型而非数目，网络设备可以为终端调度或配置一 个或至少两个BWP，这些BWP均可称为第一BWP。
其中，为了避免仅侦听某一个特定的BWP(如激活active BWP)而导致无法传输的问题，网络设备可为终端配置或调度至少两个BWP，终端可分别对配置或调度的至少两个BWP的部分或全部进行侦听，以获知各个BWP的传输信道的信道侦听结果，从而根据信道侦听结果，将传输信道空闲的BWP进行激活，得到相应的激活BWP。
步骤12：若信道侦听结果指示第一BWP中存在传输信道空闲的BWP，则在传输信道空闲的BWP中选取至少一个BWP进行激活，得到第一激活BWP。
若信道侦听结果指示第一BWP中存在传输信道空闲的BWP，则可在这些传输信道空闲的BWP中选取至少一个BWP进行激活，得到第一激活BWP，其中，选取数目可根据终端能力确定，如终端同时最多支持的激活BWP数目等。
步骤13：在第一激活BWP上，向网络设备发送信息。
终端在激活第一激活BWP后，在这些BWP上向网络设备发送上行信息。
其中，值得指出的是，终端可同时支持一个激活BWP，或至少两个激活BWP进行数据传输，下面本实施例将结合不同的终端能力对非授权频段下的信息传输方法做详细说明。
场景一、终端仅支持一个激活BWP
虽然终端同时仅支持一个激活BWP，但网络设备仍可为终端配置至少两个BWP作为候选传输资源。终端可每次仅侦听一个BWP，具体地，步骤11包括：依次对非授权频段中的第一带宽部分BWP中每个BWP的传输信道进行侦听，得到信道侦听结果。
其中，对于第一BWP的侦听顺序可按照以下方式实现：对非授权频段的第一BWP中上一次传输所使用的激活BWP的传输信道进行侦听；若侦听到激活BWP的传输信道为忙，则依次侦听第一BWP中的其他BWP，得到信道侦听结果。如图2所示，终端优先侦听上一次使用的激活BWP(如图2中BWP3)，若侦听到该BWP的传输信道为忙，则按照顺序依次侦听其他BWP(如图2中BWP1和BWP2)。
步骤12包括：将首次侦听到第一BWP中传输信道空闲的BWP进行激活，得到第一激活BWP。
终端按照上述方式依次对第一BWP中的BWP进行侦听，并将侦听到传输信道空闲的第一个BWP进行激活，得到第一激活BWP。具体地，终端同一时刻只能在一个active BWP上传输，终端在Pcell/PScell有一个active BWP，在Scell即非授权频段上有一个active BWP。为了在非授权频段上进行上行传输，终端在所有收到上行调度信息(UL grant)或上行预配置信息的BWP上按顺序进行侦听。如图2所示，优先侦听上一次的active BWP(如图中BWP3)，若该BWP的传输信道空闲，则激活该BWP的到第一激活BWP。若该BWP的传输信道为忙，则可以按顺序侦听其他BWP，将侦听到的第一个传输信道空闲的BWP(如图2中BWP1)进行激活，得到第一激活BWP。其中值得指出的是，在确定第一激活BWP后，即使还有其他剩余的BWP(如图2中的BWP2)未进行侦听，这时也无需再对其进行侦听。
场景二、终端支持至少两个激活BWP
具体地，步骤11包括：对非授权频段中的第一带宽部分BWP中的全部BWP的传输信道同时进行侦听，得到信道侦听结果。即终端对上行授权调度信息和/或上行传输资源预配置信息对应的所有BWP(configured BWP)进行侦听。
若终端接收到上行授权调度信息和/或上行传输资源预配置信息对应的的BWP数目等于终端最大支持的激活BWP时，步骤12包括：若信道侦听结果指示第一BWP中的全部BWP的传输信道均处于空闲状态，则将第一BWP中的全部BWP进行激活，得到第一激活BWP；或者，若信道侦听结果指示第一BWP中的部分BWP的传输信道空闲，则将传输信道空闲的全部BWP进行激活，得到第一激活BWP，并继续对第一BWP中的其他BWP的传输信道进行侦听，若侦听到其他BWP的传输信道空闲，则将其他BWP进行激活并补充至第一激活BWP中。
具体地，假设终端同一时刻可以在多个active BWP上传输时，终端在Pcell/PScell有多个(如Mp个)active BWP，在Scell即非授权频段上有Ms个active BWP。网络设备为终端配置Pcell/PScell上的BWP(configured BWP) 的个数是Cp，在Scell上配置的BWP的个数是Cs，即第一BWP中BWP的个数为Cs。其中，Mp≤Cp，Ms≤Cs。
其中，当Ms＝Cs时，若终端第一次侦听时侦听到第一BWP中的所有BWP的传输信道均为空闲，那么对第一BWP中的全部BWP进行激活，得到第一激活BWP。若终端在首次侦听时，侦听到第一BWP中的部分BWP的传输信道空闲，那么终端将传输信道空闲的所有BWP进行激活，得到第一激活BWP。进一步地，终端还可以继续对侦听到为忙的BWP进行侦听，在后续侦听到该BWP的传输信道空闲时将其进行激活，得到新的激活BWP并补充至第一激活BWP中。其中，值得指出的是，所有BWP之间是独立的，每个BWP的MCOT也是独立的，终端在每个BWP中MCOT的结束时间可能不一样。当在某个BWP的MCOT结束后，根据网络设备发送的上行授权调度和/或免授权(grant free)的数据确定是否还要继续侦听该BWP的传输信道。其中值得指出的是，该场景与场景一中侦听方式不同的是，终端不再按顺序依次对第一BWP中的每个BWP的传输信道进行侦听，而是同时在所有收到UL grant信息和/或者上行传输资源预配置信息对应的BWP上进行侦听，对所有侦听到传输信道空闲的BWP进行激活，得到第一激活BWP，此外，终端还进一步在侦听到传输信道为忙的BWP上继续侦听，直到侦听到该BWP的传输信道空闲或侦听超时。
若网络设备为终端调度的BWP数目大于终端最大支持的激活BWP时，步骤11还包括：在非授权频段中选取第一BWP中的第一预设数目Ms个BWP的传输信道同时进行侦听，得到信道侦听结果。其中，Ms为正整数，且小于非授权频段中第一BWP中BWP的总数。
步骤12包括：若信道侦听结果指示第一BWP中Ms个BWP的传输信道均处于空闲状态，则将Ms个BWP进行激活，得到第一激活BWP；或者，若信道侦听结果指示第一BWP的Ms个BWP中存在传输信道空闲的部分BWP，则将传输信道空闲的全部BWP进行激活，得到第一激活BWP，并继续对第一BWP中的其他BWP的传输信道进行侦听，若侦听到其他BWP的传输信道空闲，则将其他BWP进行激活并补充至第一激活BWP中。
具体地，假设终端同一时刻可以在多个active BWP上传输时，终端在 Pcell/PScell有多个(如Mp个)active BWP，在Scell即非授权频段上有Ms个active BWP。网络设备为终端配置Pcell/PScell上的BWP(configured BWP)的个数是Cp，在Scell上配置的BWP的个数是Cs，即第一BWP中BWP的个数为Cs。其中，Mp≤Cp，Ms≤Cs。当Ms＜Cs时，终端在第一BWP中选出Ms个BWP进行侦听，若侦听到这Ms个BWP的传输信道均为空闲，则对Ms个BWP进行激活得到第一激活BWP。若侦听到这Ms个BWP中仅有部分BWP(如Ms’个)的传输信道空闲，则将传输信道空闲的全部BWP进行激活得到第一激活BWP，同时终端还继续在第一BWP中除Ms’个BWP之外的其他BWP上侦听，从而另外选取Ms-Ms’个传输信道空闲的BWP补充至第一激活BWP中。其中值得指出的是，终端选取的Ms个BWP的方式有主动选取和被动选取两种，其中主动选取为网络设备向终端发送为其配置的所有BWP相应的UL grant，终端从这些BWP中选出Ms个进行侦听。被动选取为网络设备在为终端配置的BWP中选出Ns个BWP，将这Ns个BWP对应的UL grant发送至终端，终端在收到UL grant的BWP上进行侦听。
以上对终端仅支持一个激活BWP和至少两个激活BWP的场景中，网络设备如何侦听并确定第一激活BWP的方式进行了说明，另外，终端在对第一BWP进行侦听之前还包括：接收网络设备发送的非授权频段中至少一个BWP的上行授权调度信息和/或上行传输资源预配置信息；根据上行授权调度信息和/或上行传输资源预配置信息确定对应的第一BWP。即终端接收网络设备发送的上行授权调度信息和/或上行传输资源预配置信息，解析上行授权调度信息和/或上行传输资源预配置信息以确定第一BWP。如图3所示，网络设备需要提前向终端发送N个BWP对应的UL grant，其中，N≤Cs。这样终端在检测传输信道空闲的BWP后，可以按照终端发送的该BWP的UL grant或者按照上行传输资源预配置信息进行上行传输。其中，网络设备发送的不同BWP的UL grant的数据信息可以是一样的，即在不同的BWP调度传输相同的数据。
进一步地，步骤13包括：在激活第一激活BWP的下一个可用的传输时间单元内，在第一激活BWP上，向网络设备发送信息；其中，传输时间单元包括：时隙slot或微时隙mini-slot。终端在激活第一激活BWP后，在Scell 的下一个可用的传输时间单元内，在第一激活BWP上向网络设备发送上行信息。如图3所示，若网络设备的调度是基于slot的，则终端激活第一激活BWP后开始发送占用信号(reservation signal)，并从下一个slot开始按照UL grant信息发送上行信息。若网络设备的调度是基于mini-slot，则网络设备预先会针对各个BWP发送某一种或者几种mini-slot对应的UL grant信息，终端在激活第一激活BWP后发送reservation signal，并在下一个mini-slot允许传输的时刻开始进行上行传输。其中值得指出是，网络设备需要在全部发送了UL grant的BWP上进行接收，对于终端仅支持一个激活BWP的场景，网络设备一旦在某个BWP上接收到了数据，就意味着终端选择或者激活了该BWP，后续在该BWP的MCOT时间内网络设备仅需要在该BWP上接收数据即可。
本公开实施例的非授权频段下的信息传输方法中，对于上行传输，终端在非授权频段上针对多个配置的BWP进行侦听，将侦听到传输信道空闲的BWP进行激活，得到第一激活BWP，并在第一激活BWP上向网络设备发送上行信息，这样通过对多个BWP进行侦听，在一个BWP忙时还可利用其它BWP进行传输，从而提高资源利用率。

以上实施例从终端侧介绍了不同场景下的非授权频段的信息传输方法，下面将结合附图对与其对应的网络设备侧的非授权频段下的信息传输方法及终端做进一步介绍。
如图6所示，本公开实施例还提供了一种非授权频段下的信息传输方法，应用于网络设备，包括：
步骤61：向终端发送用于指示非授权频段中至少一个BWP的上行授权调度信息和/或上行传输资源预配置信息。

其中，传输时间单元包括：时隙slot或微时隙mini-slot。网络设备在向终端发送了上行授权调度信息和/或上行传输资源预配置信息后，需要在全部发送了UL grant的BWP上进行接收，一旦在某个BWP上接收到了数据，就意味着终端选择或者激活了该BWP，后续在该BWP的MCOT时间内网络设备仅需要在该BWP上接收数据即可。
以上实施例介绍了不同场景下的非授权频段的信息传输方法，下面将结合附图对与其对应的网络设备做进一步介绍。
如图7所示，本公开实施例的网络设备700，能实现上述实施例中向终端发送用于指示非授权频段中至少一个BWP的上行授权调度信息和/或上行传输资源预配置信息，在至少一个BWP上接收终端发送的信息方法的细节，并达到相同的效果，该网络设备700具体包括以下功能模块：

接收模块720，用于在至少一个BWP上接收终端发送的信息；其中，传输时间单元包括：时隙slot或微时隙mini-slot。
需要说明的是，应理解以上网络设备和终端的各个模块的划分仅仅是一种逻辑功能的划分，实际实现时可以全部或部分集成到一个物理实体上，也可以物理上分开。且这些模块可以全部以软件通过处理元件调用的形式实现；也可以全部以硬件的形式实现；还可以部分模块通过处理元件调用软件的形式实现，部分模块通过硬件的形式实现。例如，确定模块可以为单独设立的处理元件，也可以集成在上述装置的某一个芯片中实现，此外，也可以以程序代码的形式存储于上述装置的存储器中，由上述装置的某一个处理元件调用并执行以上确定模块的功能。其它模块的实现与之类似。此外这些模块全部或部分可以集成在一起，也可以独立实现。这里所述的处理元件可以是一种集成电路，具有信号的处理能力。在实现过程中，上述方法的各步骤或以上各个模块可以通过处理器元件中的硬件的集成逻辑电路或者软件形式的指 令完成。
